Dominant individuals report high levels of self-sufficiency, self-esteem, and authoritarianism. The lay stereotype suggests that such individuals ignore information from others, preferring to make their own choices. However, the nonhuman animal literature presents a conflicting view, suggesting that dominant individuals are avid social learners, whereas subordinates focus on learning from private experience. Whether dominant humans are best characterized by the lay stereotype or the animal view is currently unknown. Here, we present a "social dominance paradox": using self-report scales and computerized tasks, we demonstrate that socially dominant people explicitly value independence, but, paradoxically, in a complex decision-making task, they show an enhanced reliance (relative to subordinate individuals) on social learning. More specifically, socially dominant people employed a strategy of copying other agents when the agents' responses had a history of being correct. However, in humans, two subtypes of dominance have been identified: aggressive and social. Aggressively dominant individuals, who are as likely to "get their own way" as socially dominant individuals but who do so through the use of aggressive or Machiavellian tactics, did not use social information, even when it was beneficial to do so. This paper presents the first study of dominance and social learning in humans and challenges the lay stereotype in which all dominant individuals ignore others' views. The more subtle perspective we offer could have important implications for decision making in both the boardroom and the classroom. Copyright © 2014 Elsevier Ltd. All rights reserved.

Full Text Available AIM:To study the distribution of the dominant eye in people with myopia and astigmatism and the relationship between dominant eye and the two. METHODS:Three hundred and eighty patients who went our hospital for optometry consecutively were enrolled, using hole-in-card method to detect the dominant eye. The records of age, gender, vision acuity and other related information were analyzed by SPSS 11.0 software. RESULTS: 1Most of the dominant eyes were right eyes which accounted for 66.84%, and the ametropia degree on right eyes was relatively higher; 2Dominant eyes had no significant association with gender, age and uncorrected vision acuity(P>0.05; 3There was no significant correlation between the dominant eyes and ametropia degree(P>0.05. But in the group which the difference of cylinder degree between two eyes were ≥1D, only 20% of the dominant eyes had higher ametropia degree, which was different from the other two groups. CONCLUSION:High cylinder of anisometropia may affect the choice of the dominant eye. High sphere of anisometropia may be the result of the choice of dominant eye.

A Qualitative Exploration of Gender Identity in Young People who identify as Neither Male nor Female
Boddington, Ellen
2016-01-01
The dominant approach to categorising gender in western cultures, follows a binary\\ud system, where the gender of an individual must be either male or female. However,\\ud some individuals feel that their gender identity is neither male nor female, and may\\ud define themselves as non-binary. Non-binary gender has predominantly been\\ud encompassed within wider transgender research and, therefore, little is known about\\ud how young people who identify as non-binary describe their gender identity...

System reliability analysis using dominant failure modes identified by selective searching technique
International Nuclear Information System (INIS)
Kim, Dong-Seok; Ok, Seung-Yong; Song, Junho; Koh, Hyun-Moo
2013-01-01
The failure of a redundant structural system is often described by innumerable system failure modes such as combinations or sequences of local failures. An efficient approach is proposed to identify dominant failure modes in the space of random variables, and then perform system reliability analysis to compute the system failure probability. To identify dominant failure modes in the decreasing order of their contributions to the system failure probability, a new simulation-based selective searching technique is developed using a genetic algorithm. The system failure probability is computed by a multi-scale matrix-based system reliability (MSR) method. Lower-scale MSR analyses evaluate the probabilities of the identified failure modes and their statistical dependence. A higher-scale MSR analysis evaluates the system failure probability based on the results of the lower-scale analyses. Three illustrative examples demonstrate the efficiency and accuracy of the approach through comparison with existing methods and Monte Carlo simulations. The results show that the proposed method skillfully identifies the dominant failure modes, including those neglected by existing approaches. The multi-scale MSR method accurately evaluates the system failure probability with statistical dependence fully considered. The decoupling between the failure mode identification and the system reliability evaluation allows for effective applications to larger structural systems

Identify the dominant variables to predict stream water temperature
Chien, H.; Flagler, J.
2016-12-01
Stream water temperature is a critical variable controlling water quality and the health of aquatic ecosystems. Accurate prediction of water temperature and the assessment of the impacts of environmental variables on water temperature variation are critical for water resources management, particularly in the context of water quality and aquatic ecosystem sustainability. The objective of this study is to measure stream water temperature and air temperature and to examine the importance of streamflow on stream water temperature prediction. The measured stream water temperature and air temperature will be used to test two hypotheses: 1) streamflow is a relatively more important factor than air temperature in regulating water temperature, and 2) by combining air temperature and streamflow data stream water temperature can be more accurately estimated. Water and air temperature data loggers are placed at two USGS stream gauge stations #01362357and #01362370, located in the upper Esopus Creek watershed in Phonecia, NY. The ARIMA (autoregressive integrated moving average) time series model is used to analyze the measured water temperature data, identify the dominant environmental variables, and predict the water temperature with identified dominant variable. The preliminary results show that streamflow is not a significant variable in predicting stream water temperature at both USGS gauge stations. Daily mean air temperature is sufficient to predict stream water temperature at this site scale.

To identify relationships between self-reported limb preferences and performance measures for determining limb dominance in adolescent female basketball players. Cross-sectional cohort study. Forty adolescent female basketball players. Participants provided self-reported preferred kicking and jumping limbs, then completed 3 trials of a single-limb countermovement hop (HOPVER) and unilateral triple hop for distance (HOPHOR) on each limb. Each test was used to independently define limb dominance by the limb that produced the largest maximum vertical height and horizontal distance, respectively. Chi-square tests for independence identified a significant relationship between self-reported preferred kicking and jumping legs (χ = 7.41, P = 0.006). However, no significant relationships were found when comparing self-reported preference to measures of performance during the HOPHOR (χ = 0.33, P = 0.57) or HOPVER (χ = 0.06, P = 0.80). In addition, the 2 performance measures did not consistently produce the same definition of limb dominance among individuals (χ = 1.52, P = 0.22). Self-selection of the dominant limb is unrelated to performance. Furthermore, limb dominance, as defined by vertical jump height, is unrelated to limb dominance defined by horizontal jump distance. The results of this study call into question the validity of consistently defining limb dominance by self-reported measures in adolescent female basketball players.

A thorough understanding of why we hold a cell phone to a particular ear may be of importance when studying the impact of cell phone safety. To determine if there is an obvious association between sidedness of cell phone use and auditory hemispheric dominance (AHD) or language hemispheric dominance (LHD). It is known that 70% to 95% of the population are right-handed, and of these, 96% have left-brain LHD. We have observed that most people use their cell phones in their right ear. An Internet survey was e-mailed to individuals through surveymonkey.com. The survey used a modified Edinburgh Handedness Inventory protocol. Sample questions surveyed which hand was used to write with, whether the right or left ear was used for phone conversations, as well as whether a brain tumor was present. General community. An Internet survey was randomly e-mailed to 5000 individuals selected from an otology online group, patients undergoing Wada testing and functional magnetic resonance imaging, as well as persons on the university listserv, of which 717 surveys were completed. Determination of hemispheric dominance based on preferred ear for cell phone use. A total of 717 surveys were returned. Ninety percent of the respondents were right handed, and 9% were left handed. Sixty-eight percent of the right-handed people used the cell phone in their right ear, 25% in the left ear, and 7% had no preference. Seventy-two of the left-handed respondents used their left ear, 23% used their right ear, and 5% had no preference. Cell phone use averaged 540 minutes per month over the past 9 years. An association exists between hand dominance laterality of cell phone use (73%) and our ability to predict hemispheric dominance. Most right-handed people have left-brain LHD and use their cell phone in their right ear. Similarly, most left-handed people use their cell phone in their left ear. Our study suggests that AHD may differ from LHD owing to the difference in handedness and cell phone ear use

Identifying Indigenous Peoples globally is complex and contested despite there being an estimated 370 million living in 70 countries. The specific context and use of locally relevant and clear definitions or characterizations of Indigenous Peoples is important for recognizing unique health risks Indigenous Peoples face, for understanding local Indigenous health aspirations and for reflecting on the need for culturally disaggregated data to plan meaningful research and health improvement programs. This paper explores perspectives on defining Indigenous Peoples and reflects on challenges in identifying Indigenous Peoples. Literature reviews and Internet searches were conducted, and some key experts were consulted. Pragmatic and political definitions by international institutions, including the United Nations, are presented as well as characterizations of Indigenous Peoples by governments and academic researchers. Assertions that Indigenous Peoples have about definitions of indigeneity are often related to maintenance of cultural integrity and sustainability of lifestyles. Described here are existing definitions and interests served by defining (or leaving undefined) such definitions, why there is no unified definition and implications of "too restrictive" a definition. Selected indigenous identities and dynamics are presented for North America, the Arctic, Australia and New Zealand, Latin America and the Caribbean, Asia and Africa. While health researchers need to understand the Indigenous Peoples with whom they work, ultimately, indigenous groups themselves best define how they wish to be viewed and identified for research purposes.

Self-identified Obese People Request Less Money: A Field Experiment.
Proestakis, Antonios; Brañas-Garza, Pablo
2016-01-01
Empirical evidence suggests that obese people are discriminated in different social environments, such as the work place. Yet, the degree to which obese people are internalizing and adjusting their own behavior as a result of this discriminatory behavior has not been thoroughly studied. We develop a proxy for measuring experimentally the "self-weight bias" by giving to both self-identified obese ( n = 90) and non-obese ( n = 180) individuals the opportunity to request a positive amount of money after having performed an identical task. Consistent with the System Justification Theory, we find that self-identified obese individuals, due to a preexisting false consciousness , request significantly lower amounts of money than non-obese ones. A within subject comparison between self-reports and external monitors' evaluations reveals that the excessive weight felt by the "self" but not reported by evaluators captures the self-weight bias not only for obese but also for non-obese individuals. Linking our experimental results to the supply side of the labor market, we argue that self-weight bias, as expressed by lower salary requests, enhances discriminatory behavior against individuals who feel, but may not actually be, obese and consequently exacerbates the wage gap across weight.

Following on from the studies by McManus and Cornish [(1997). Fractionating handedness in mental retardation: What is the role of the cerebellum? Laterality, 2(2), 81-89] and Cornish, Pigram, and Shaw [(1997). Do anomalies of handedness exist in children with fragile-X syndrome? Laterality, 2(2), 91-101], the aim of this paper was to determine laterality in people with fragile X syndrome (FXS). The sample comprised three study groups: the first with 30 people with FXS (mean age 17.9 years), the second 34 people with various intellectual disabilities (ID, mean age 20.9 years), and the third 160 people with typical development (mean age 14.7 years). Laterality was assessed with a test adapted for this study. The results confirm the preponderance of right-handedness (93.3%) in people with FXS and present new data regarding footedness and sensory dominance (eyedness and earedness), indicating inconsistent footedness and ocular cross-dominance. Almost three-quarters (73.5%) of people with other ID were right-handed. The results corroborate those of McManus and Cornish (1997). People with FXS tend to be right-handed but have ocular cross-dominance.

Symptoms guide disease management, and patients frequently report HIV-related symptoms, but HIV symptom patterns reported by patients have not been described in the era of improved antiretroviral treatment. The objectives of our study were to investigate the prevalence and burden of symptoms in people living with HIV and attending an outpatient clinic. The prevalence, burden, and bothersomeness of symptoms reported by patients in routine clinic visits during 2011 were assessed using the 20-item HIV Symptom Index. Principal component analysis was used to identify symptom clusters and relationships between groups using appropriate statistic techniques. Two main clusters were identified. The most prevalent and bothersome symptoms were muscle aches/joint pain, fatigue, and poor sleep. A third of patients had seven or more symptoms, including the most burdensome symptoms. Even with improved antiretroviral drug side-effect profiles, symptom prevalence and burden, independent of HIV viral load and CD4+ T cell count, are high. PMID:26790340

The relative importance of fuel, topography, and weather on fire spread varies at different spatial scales, but how the relative importance of these controls respond to changing spatial scales is poorly understood. We designed a “moving window” resampling technique that allowed us to quantify the relative importance of controls on fire spread at continuous spatial scales using boosted regression trees methods. This quantification allowed us to identify the threshold value for fire size at which the dominant control switches from fuel at small sizes to weather at large sizes. Topography had a fluctuating effect on fire spread across the spatial scales, explaining 20–30% of relative importance. With increasing fire size, the dominant control switched from bottom-up controls (fuel and topography) to top-down controls (weather). Our analysis suggested that there is a threshold for fire size, above which fires are driven primarily by weather and more likely lead to larger fire size. We suggest that this threshold, which may be ecosystem-specific, can be identified using our “moving window” resampling technique. Although the threshold derived from this analytical method may rely heavily on the sampling technique, our study introduced an easily implemented approach to identify scale thresholds in wildfire regimes.

Social dominance orientation (SDO), one's degree of preference for inequality among social groups, is introduced. On the basis of social dominance theory, it is shown that (a) men are more social dominance-oriented than women, (b) high-SDO people seek hierarchy-enhancing professional roles and low-SDO people seek hierarchy-attenuating roles, (c) SDO was related to beliefs in a large number of social and political ideologies that support group-based hierarchy (e.g., meritocracy and racism) and...

People who identify as lesbian, gay, bisexual and transgender (LGBT) can face many challenges in society including accessing education, care and support appropriate to individual needs. However, there is a growing and evolving evidence base about the specific needs of people with intellectual disabilities (ID) in this regard. The aim of this review was to explore the experiences of people with ID who identified as LGBT through an examination of studies that addressed their views and highlighted specific issues, concerns and service responses. A comprehensive search of relevant databases from February 1995 to February 2015 was conducted. Studies were identified that met specific criteria that included: empirical peer reviewed studies, the use of recognised research methods and focused on people with ID whom identified as LGBT. The search yielded 161 papers in total. The search was narrowed and 37 papers were screened using rigorous inclusion and exclusion criteria. Finally, 14 papers were considered suitable for the review. The data were analysed and key themes identified that included accessing health services, gender and sexual identity, attitudes of people with ID regarding their LGBT status, and education, supports and therapeutic interventions. There is a need for service providers and carers to be more responsive to the concerns of people with ID who identify as LGBT to improve their health and well-being by reducing stigma and discrimination and by increasing awareness of their care and support needs. The implications are discussed in terms of policy, education, research and practice developments. Copyright © 2016 Elsevier Ltd. All rights reserved.

Non-domination and democratic legitimacy
DEFF Research Database (Denmark)

2015-01-01
While many regard equality as the moral foundation of democracy, republican theory grounds democracy in freedom as non-domination. The grounding of democracy in freedom has been criticized for relying on either an Aristotelian perfectionism or a Rousseauian equation of the people...... in their collective capacity and the people understood severally. The republican theory of freedom and democracy has the resources to meet these criticisms. But the most systematic elaboration of republicanism, that of Philip Pettit, achieves this by turning the relationship between freedom and democracy...

Over the last years, several initiatives on early detection and intervention have been put in place to proactively identify health and social problems in (frail) older people. An overview of the initiatives currently available in the Netherlands is lacking, and it is unknown whether they meet the preferences and needs of older people. Therefore, the objectives of this study were threefold: 1. To identify initiatives on early detection and intervention for older people in the Netherlands and compare their characteristics; 2. To explore the experiences of professionals with these initiatives; and 3. To explore to what extent existing initiatives meet the preferences and needs of older people. We performed a qualitative descriptive study in which we conducted semi-structured interviews with seventeen experts in preventive elderly care and three group interviews with volunteer elderly advisors. Data were analysed using the framework analysis method. We identified eight categories of initiatives based on the setting (e.g. general practitioner practice, hospital, municipality) in which they were offered. Initiatives differed in their aims and target groups. The utilization of peers to identify problems and risks, as was done by some initiatives, was seen as a strength. Difficulties were experienced with identifying the target group that would benefit from proactive delivery of care and support most, and with addressing prevalent issues among older people (e.g. psychosocial issues, self-reliance issues). Although there is a broad array of initiatives available, there is a discrepancy between supply and demand. Current initiatives insufficiently address needs of (frail) older people. More insight is needed in "what should be done by whom, for which target group and at what moment", in order to improve current practice in preventive elderly care.

Challenging dominant norms of masculinity for HIV prevention.
MacPhail, Catherine
2003-01-01
Within South Africa there is a growing HIV epidemic, particularly among young heterosexual people. A recent report (NMF/HSRC, 2002) indicates that levels of HIV infection among young people aged 15-24 years are 9.3% although other studies in more specific locations have shown levels to be higher than this. One of the best means of developing successful and innovative HIV prevention programmes for young people is to enhance our understandings of youth sexuality and the manner in which dominant norms contribute to the spread of sexually transmitted diseases. Social norms of masculinity are particularly important in this regard, as the manner in which 'normal' men are defined such as through acquisition of multiple partners, power over women and negative attitudes towards condoms, are often in conflict with the true emotional vulnerabilities of young men. Given the strong influence of peer groups on young people and the belief that one of the solutions to behaviour change lies in peer renegotiation of dominant norms, there is the need to begin to investigate young men who challenge dominant norms of masculinity. It is in investigating their points of view that a platform for the deconstruction of stereotypical masculinities and the reconstruction of new norms can be formed. The paper begins to consider these counter normative ideas through highlighting the discussions of young South African men aged 13-25 years in focus groups and in-depth individual interviews conducted in Gauteng Province. It is apparent that among this group there are young men challenging normative views of masculinity in a manner that could be harnessed within HIV prevention initiatives.

The conventional approach to identifying the defective gene in a family with an inherited disease is to find the disease locus through family studies. However, the rapid development and decreasing cost of next generation sequencing facilitates a more direct approach. Here, we report the identification of a frameshift mutation in LAMB3 as a cause of dominant hypoplastic amelogenesis imperfecta (AI). Whole-exome sequencing of three affected family members and subsequent filtering of shared variants, without prior genetic linkage, sufficed to identify the pathogenic variant. Simultaneous analysis of multiple family members confirms segregation, enhancing the power to filter the genetic variation found and leading to rapid identification of the pathogenic variant. LAMB3 encodes a subunit of Laminin-5, one of a family of basement membrane proteins with essential functions in cell growth, movement and adhesion. Homozygous LAMB3 mutations cause junctional epidermolysis bullosa (JEB) and enamel defects are seen in JEB cases. However, to our knowledge, this is the first report of dominant AI due to a LAMB3 mutation in the absence of JEB.

Participation rates of older people in resistance training (RT) are low despite increasing research showing many health benefits. To increase the number of older people participating in RT it is important to know what would motivate people to become involved, what motivates those who participate to continue, and the factors preventing many older people from commencing participation. To investigate these issues, a questionnaire was mailed to three groups of older people: (1) those receiving home care services, (2) members of a peak non-government seniors' organisation and (3) those participating in a specific gym-based RT programme. In total, 1327 questionnaires were returned (response rate = 42.5%). To feel good physically and mentally were the main reasons motivating participation among all three groups, and falls prevention was identified as an important motivator for the home care respondents. Pain, injury and illness were the main barriers to participating, or continuing to participate. However, medical advice was a factor influencing participation commencement. The results suggest organisations providing RT programmes for older people should tailor the promotion and delivery of programmes to address key motivators and barriers specific to each group to increase the proportion of older people initiating and continuing to engage in RT.

To describe a child-centered approach to identifying content for a novel self-report questionnaire for assessing vision-related quality of life (QoL) of visually impaired (VI) or blind (BL) children and young people. Questionnaire development. A stratified random patient sample of children and young people who are VI/BL (visual acuity in the better eye Snellen people who are VI/BL and aged 10 to 17 years (N=29). Individual interviews were conducted with a stratified random sample of 32 children and young people, aged 10 to 15 years, who were VI/BL. The interviews followed a topic guide based on vision-related issues identified from a focus group of affected children and young people, combined with a literature review and consultations with professionals. Collaborative qualitative thematic analysis was undertaken and used to derive draft items of the instrument, using the children's own language wherever possible. Items were reduced, rephrased, and refined through individual consultation, as well as an expert reference group of children and young people who were VI/BL, and supplemented by the research team's consensus. A draft 47-item instrument. A total of 874 potential questionnaire items were initially generated spanning the following domains: social relations, acceptance, and participation; independence and autonomy; psychological and emotional well-being; future-aspirations and fears; functioning-home, school, and leisure; and treatment of eye condition. This was eventually reduced to a 47-item instrument with each item presented as a vignette describing a QoL issue from an "illustrative" child's perspective. Thus, the responding child reports on how much he/she is presently like and how much he/she wishes to be like that child, using a 4-point Likert-type scale. We demonstrate that a child-centered approach to identifying the content for a self-report vision-related QoL questionnaire is feasible. We suggest this approach is critical to accurately capturing

Perceived breast cancer risk: heuristic reasoning and search for a dominance structure.
Katapodi, Maria C; Facione, Noreen C; Humphreys, Janice C; Dodd, Marylin J
2005-01-01
Studies suggest that people construct their risk perceptions by using inferential rules called heuristics. The purpose of this study was to identify heuristics that influence perceived breast cancer risk. We examined 11 interviews from women of diverse ethnic/cultural backgrounds who were recruited from community settings. Narratives in which women elaborated about their own breast cancer risk were analyzed with Argument and Heuristic Reasoning Analysis methodology, which is based on applied logic. The availability, simulation, representativeness, affect, and perceived control heuristics, and search for a dominance structure were commonly used for making risk assessments. Risk assessments were based on experiences with an abnormal breast symptom, experiences with affected family members and friends, beliefs about living a healthy lifestyle, and trust in health providers. Assessment of the potential threat of a breast symptom was facilitated by the search for a dominance structure. Experiences with family members and friends were incorporated into risk assessments through the availability, simulation, representativeness, and affect heuristics. Mistrust in health providers led to an inappropriate dependence on the perceived control heuristic. Identified heuristics appear to create predictable biases and suggest that perceived breast cancer risk is based on common cognitive patterns.

Status Decreases Dominance in the West but Increases Dominance in the East.
Kuwabara, Ko; Yu, Siyu; Lee, Alice J; Galinsky, Adam D
2016-02-01
In the experiments reported here, we integrated work on hierarchy, culture, and the enforcement of group cooperation by examining patterns of punishment. Studies in Western contexts have shown that having high status can temper acts of dominance, suggesting that high status may decrease punishment by the powerful. We predicted that high status would have the opposite effect in Asian cultures because vertical collectivism permits the use of dominance to reinforce the existing hierarchical order. Across two experiments, having high status decreased punishment by American participants but increased punishment by Chinese and Indian participants. Moreover, within each culture, the effect of status on punishment was mediated by feelings of being respected. A final experiment found differential effects of status on punishment imposed by Asian Americans depending on whether their Asian or American identity was activated. Analyzing enforcement through the lens of hierarchy and culture adds insight into the vexing puzzle of when and why people engage in punishment. © The Author(s) 2015.

Full Text Available Abstract Background Leopards are the most widely distributed of the large cats, ranging from Africa to the Russian Far East. Because of habitat fragmentation, high human population densities and the inherent adaptability of this species, they now occupy landscapes close to human settlements. As a result, they are the most common species involved in human wildlife conflict in India, necessitating their monitoring. However, their elusive nature makes such monitoring difficult. Recent advances in DNA methods along with non-invasive sampling techniques can be used to monitor populations and individuals across large landscapes including human dominated ones. In this paper, we describe a DNA-based method for leopard individual identification where we used fecal DNA samples to obtain genetic material. Further, we apply our methods to non-invasive samples collected in a human-dominated landscape to estimate the minimum number of leopards in this human-leopard conflict area in Western India. Results In this study, 25 of the 29 tested cross-specific microsatellite markers showed positive amplification in 37 wild-caught leopards. These loci revealed varied levels of polymorphism (four-12 alleles and heterozygosity (0.05-0.79. Combining data on amplification success (including non-invasive samples and locus specific polymorphisms, we showed that eight loci provide a sibling probability of identity of 0.0005, suggesting that this panel can be used to discriminate individuals in the wild. When this microsatellite panel was applied to fecal samples collected from a human-dominated landscape, we identified 7 individuals, with a sibling probability of identity of 0.001. Amplification success of field collected scats was up to 72%, and genotype error ranged from 0-7.4%. Conclusion Our results demonstrated that the selected panel of eight microsatellite loci can conclusively identify leopards from various kinds of biological samples. Our methods can be used to

To examine discrimination and resilience experiences of people who identify as transgender and establish potential health service responses. People who identify as transgender face many challenges in society in terms of the knowledge, understanding and acceptance of a person's gender identity. A narrative review of quantitative empirical research. A comprehensive search of CINAHL, MEDLINE, PsycINFO and Sociological Abstracts electronic databases from 2006-2016 was conducted. The search yielded 1,478 papers and following the application of rigorous inclusion and exclusion criteria a total of 19 papers were included in the review. The findings reveal that there is a need to ensure that the needs of transgender people are represented, fully integrated and clearly linked to outcomes that improve their health and quality of life. Discrimination experiences can result in poorer health outcomes; however, many people have developed resilience and positive coping strategies. Nurses need to recognise and respond appropriately to the care and treatment needs of this population. Comprehensive nursing assessments and plans of care that encompass all aspects of the person should be in place supported by clear policy guidelines and evidence-based research. The education requirements of practitioners are outlined. © 2017 John Wiley & Sons Ltd.

When does "economic man" dominate social behavior?
Camerer, Colin F; Fehr, Ernst
2006-01-06
The canonical model in economics considers people to be rational and self-regarding. However, much evidence challenges this view, raising the question of when "Economic Man" dominates the outcome of social interactions, and when bounded rationality or other-regarding preferences dominate. Here we show that strategic incentives are the key to answering this question. A minority of self-regarding individuals can trigger a "noncooperative" aggregate outcome if their behavior generates incentives for the majority of other-regarding individuals to mimic the minority's behavior. Likewise, a minority of other-regarding individuals can generate a "cooperative" aggregate outcome if their behavior generates incentives for a majority of self-regarding people to behave cooperatively. Similarly, in strategic games, aggregate outcomes can be either far from or close to Nash equilibrium if players with high degrees of strategic thinking mimic or erase the effects of others who do very little strategic thinking. Recently developed theories of other-regarding preferences and bounded rationality explain these findings and provide better predictions of actual aggregate behavior than does traditional economic theory.

Brazilian Credit Union Member Groups: Borrower-dominated, Saver-dominated or Neutral Behavior?
Directory of Open Access Journals (Sweden)
Valéria Gama Fully Bressan
2013-01-01
Full Text Available Theoretical models concerning Credit Unions (CUs suggest that the type of CU domination determines the way it allocates the monetary value it generates. A borrower- (saver- dominated CU benefits borrower (saver members at the expenses of saver (borrower members, and a neutral CU equally benefits its member groups.This paper applies direct measure of monetary benefits to each member group (Patin & McNiel, 1991a to testfor the existence of dominated behavior in Brazilian CUs, and is the first to apply panel data regressions to identify the determinants of CUs behavior. We use a unique panel data with 40,664 observations taken from 533 CUs affiliated with the largest Brazilian cooperative network. Results indicate Brazilian CUs are dominated by borrowers, but behave close to neutrality. Panel regression estimates show that common or multiple bond type,size and overdue loans of a CU have no effect on its behavior, the greater the total amount of loans over social capital and adjusted equity over total assets are the more likely a CU is borrower dominated, and the greater the age and current operational expenses over total asset of a CU are the more likely a CU is saver dominated.

Hand dominance in upper extremity musculoskeletal disorders.
Shiri, Rahman; Varonen, Helena; Heliövaara, Markku; Viikari-Juntura, Eira
2007-05-01
To investigate the role of hand dominance in common upper extremity musculoskeletal disorders (UEMSD) in a population study. The target population consisted of a representative sample of people aged 30 years or older residing in Finland during 2000-2001. Of the 7977 eligible subjects, 6254 (78.4%) were included in the study. The prevalence of UEMSD was as follows: rotator cuff tendinitis 3.8%, bicipital tendinitis 0.5%, lateral epicondylitis 1.1%, medial epicondylitis 0.3%, carpal tunnel syndrome (CTS) 3.8%, and surgery due to CTS 1.3%. CTS was 2.5 times as prevalent in women as men, whereas the other UEMSD were as common in both sexes. Rotator cuff and bicipital tendinitis and medial epicondylitis were more prevalent in the dominant arm only in women, whereas lateral epicondylitis was more prevalent in the dominant elbow in both sexes. The higher prevalence of rotator cuff and bicipital tendinitis in the dominant side persisted beyond working age. The prevalence of CTS did not differ by hand dominance. Dominant hand had been operated more frequently for CTS in women. Our findings show that UEMSD are more prevalent in the dominant than nondominant arm mainly in women. For shoulder tendinitis, the difference persists throughout adult age. Physical load factors may have long-lasting effects on the shoulder and they may play a greater role in women than men.

To prospectively evaluate the accuracy of a predictive model to identify homeless people at risk of representation to an emergency department. A prospective cohort analysis utilised one month of data from a Principal Referral Hospital in Melbourne, Australia. All visits involving people classified as homeless were included, excluding those who died. Homelessness was defined as living on the streets, in crisis accommodation, in boarding houses or residing in unstable housing. Rates of re-presentation, defined as the total number of visits to the same emergency department within 28 days of discharge from hospital, were measured. Performance of the risk screening tool was assessed by calculating sensitivity, specificity, positive and negative predictive values and likelihood ratios. Over the study period (April 1, 2009 to April 30, 2009), 3298 presentations from 2888 individuals were recorded. The homeless population accounted for 10% (n=327) of all visits and 7% (n=211) of all patients. A total of 90 (43%) homeless people re-presented to the emergency department. The predictive model included nine variables and achieved 98% (CI, 0.92-0.99) sensitivity and 66% (CI, 0.57-0.74) specificity. The positive predictive value was 68% and the negative predictive value was 98%. The positive likelihood ratio 2.9 (CI, 2.2-3.7) and the negative likelihood ratio was 0.03 (CI, 0.01-0.13). The high emergency department re-presentation rate for people who were homeless identifies unresolved psychosocial health needs. The emergency department remains a vital access point for homeless people, particularly after hours. The risk screening tool is key to identify medical and social aspects of a homeless patient's presentation to assist early identification and referral.

Agents with left and right dominant hemispheres and quantum statistics
Ezhov, Alexandr A.; Khrennikov, Andrei Yu.
2005-01-01
We present a multiagent model illustrating the emergence of two different quantum statistics, Bose-Einstein and Fermi-Dirac, in a friendly population of individuals with the right-brain dominance and in a competitive population of individuals with the left-brain hemisphere dominance, correspondingly. Doing so, we adduce the arguments that Lefebvre’s “algebra of conscience” can be used in a natural way to describe decision-making strategies of agents simulating people with different brain dominance. One can suggest that the emergence of the two principal statistical distributions is able to illustrate different types of society organization and also to be used in order to simulate market phenomena and psychic disorders, when a switching of hemisphere dominance is involved.

Left- or right-handedness is a common human trait, and it has been previously reported that human nasal airflow dominance correlates with hand dominance. Any relationship between hand dominance and nasal airflow dominance would be unusual. This study aimed to measure nasal airflow and look for any relationship to handedness. The modified Glatzel mirror was used to record the dominant nasal passage at 15-minute intervals over a 6-hour period in 29 healthy participants consisting of 15 left-handers and 14 right-handers. In left-handers, the percentage of time that the left nasal passage was dominant ranged from 0 to 100 per cent. In right-handers, the percentage of time that the right nasal passage was dominant ranged from 4.2 to 95.8 per cent. No correlation between nasal airflow dominance and hand dominance was identified. The results do not support the hypothesis that nasal airflow and handedness are related.

Full Text Available Considering how people perceive risks to their livelihoods from local wildlife is central to (i understanding the impact of crop damage by animals on local people and (ii recognising how this influences their interactions with, and attitudes towards, wildlife. Participatory risk mapping (PRM is a simple, analytical tool that can be used to identify and classify risk within communities. Here we use it to explore local people's perceptions of crop damage by wildlife and the animal species involved. Interviews (n = 93, n = 76 and seven focus groups were conducted in four villages around Budongo Forest Reserve, Uganda during 2004 and 2005. Farms (N = 129 were simultaneously monitored for crop loss. Farmers identified damage by wildlife as the most significant risk to their crops; risk maps highlighted its anomalous status compared to other anticipated challenges to agricultural production. PRM was further used to explore farmers' perceptions of animal species causing crop damage and the results of this analysis compared with measured crop losses. Baboons (Papio anubis were considered the most problematic species locally but measurements of loss indicate this perceived severity was disproportionately high. In contrast goats (Capra hircus were considered only a moderate risk, yet risk of damage by this species was significant. Surprisingly, for wild pigs (Potamochoerus sp, perceptions of severity were not as high as damage incurred might have predicted, although perceived incidence was greater than recorded frequency of damage events. PRM can assist researchers and practitioners to identify and explore perceptions of the risk of crop damage by wildlife. As this study highlights, simply quantifying crop loss does not determine issues that are important to local people nor the complex relationships between perceived risk factors. Furthermore, as PRM is easily transferable it may contribute to the identification and development of

Self-disclosing my ostomy to the dominant culture: an autoethnography.
Frohlich, Dennis Owen
2012-01-01
Living with an ostomy is a major change to a person's body and poses difficult questions about how to disclose personal medical information to others. This autoethnography examines my time with an ostomy through the lens of co-cultural theory and sheds light on how people with ostomies communicate with the dominant culture, in this case people without ostomies. I discuss how my communication goals and approaches evolved over time.

This study explored the personalized and collective participation needs of people with acquired brain injury (ABI) living in a future shared community smart home. An action research study was conducted with 16 persons, seven with ABI, four caregivers and five rehabilitation or smart home healthcare providers. Twelve interviews and two focus groups were conducted, audiotaped, transcribed and analyzed for content. Seventy personalized and 18 collective participation needs were reported related to daily and social activities. Personalized needs concerned interpersonal relationships, general organization of activities, leisure, housing, fitness and nutrition. Collective needs related mainly to housing, general organization of activities and nutrition. Personalized and collective participation needs of people with ABI planning to live in a community smart home are diverse and concern daily as well as social activities. Implications for Rehabilitation To meet participation needs of people with ABI, the design of smart homes must consider all categories of daily and social activities. Considering personalized and collective needs allowed identifying exclusive examples of each. As some persons with ABI had difficulty identifying their needs as well as accepting their limitations and the assistance required, rehabilitation professionals must be involved in needs identification.

Full Text Available Customer relationship management (CRM is a popular field of research at the intersection of a number of disciplines such as marketing, business management, information technologies and computer sciences, closely followed by scholars, company executives, and consultant firms. The current global competitive environment leads firms to develop and strengthen their relations with their customers, their most valuable assets. Long-term, mutually beneficial relations that businesses build with their customers provide an important competitive advantage against competitors. An effective and efficient customer relationship management would turn into customer satisfaction and loyalty, lower costs, and higher shareholder value for the firms. The aim of this study is to identify the dominant perspective and its sub-concepts used on scholars’ conceptualization of CRM employed in customer relationship management literature. With this purpose, a literature review was conducted for the period of 2000-2010. The results of the study show that customer relationship management was mostly conceptualized as a strategy by the scholars.

Essentials Three dominant variants for the autosomal recessive bleeding disorder type-8 have been described. To date, there has been no phenotype/genotype correlation explaining their dominant transmission. Proline plays an important role in P2Y12R ligand binding and signaling defects. P2Y12R homodimer formation is critical for the receptor function and signaling. Background Although inherited platelet disorders are still underdiagnosed worldwide, advances in molecular techniques are improving disease diagnosis and patient management. Objective To identify and characterize the mechanism underlying the bleeding phenotype in a Caucasian family with an autosomal dominant P2RY12 variant. Methods Full blood counts, platelet aggregometry, flow cytometry and western blotting were performed before next-generation sequencing (NGS). Detailed molecular analysis of the identified variant of the P2Y12 receptor (P2Y12R) was subsequently performed in mammalian cells overexpressing receptor constructs. Results All three referred individuals had markedly impaired ADP-induced platelet aggregation with primary wave only, despite normal total and surface P2Y12R expression. By NGS, a single P2RY12:c.G794C substitution (p.R265P) was identified in all affected individuals, and this was confirmed by Sanger sequencing. Mammalian cell experiments with the R265P-P2Y12R variant showed normal receptor surface expression versus wild-type (WT) P2Y12R. Agonist-stimulated R265P-P2Y12R function (both signaling and surface receptor loss) was reduced versus WT P2Y12R. Critically, R265P-P2Y12R acted in a dominant negative manner, with agonist-stimulated WT P2Y12R activity being reduced by variant coexpression, suggesting dramatic loss of WT homodimers. Importantly, platelet P2RY12 cDNA cloning and sequencing in two affected individuals also revealed three-fold mutant mRNA overexpression, decreasing even further the likelihood of WT homodimer formation. R265 located within extracellular loop 3 (EL3) is

2015-01-01
We studied play behavior of customers of betting offices. A study included 216 people who were surveyed using the Canadian problem gambling index. According to the results of the test, we stratified the sample by the risk of pathological gambling. The high prevalence of people with medium and high risk of pathological gambling was identified. Significant differences in the characteristics of gambling behavior were found. We described the qualitative and quantitative indicators of gaming activity that proved the appearance of the addicted dominant in the high-risk group (changes in the motivational sphere, financial loss, using alternative forms of the game, the regular play activity and low level of the reflection of problems caused by the game).

Prejudice, Social Dominance, and Similarity among People who Favor Integration of Minorities.
Martínez, Carmen; Saiz, José; Angosto, Josefa
2016-04-12
This study examines differences in prejudice, perceived similarity, and social dominance in members of the majority who favor integration as a means of minority acculturation. A total of 342 non-Gypsy Spanish participants filled out a questionnaire about their relationship to one of three outgroups: Maghrebians, Gypsies, and Latin Americans. Hierarchical cluster analysis showed that a three-cluster solution was most fitting for every outgroup. ANOVAs applied to the three clusters indicated significant differences in prejudice, perceived similarity, and social dominance. Referring to Gypsies the largest effect size was observed in manifest prejudice (η2 = .63), in Maghrebians, the largest effect size was observed in subtle prejudice (η2 =.77), while for Latin Americans, perceived similarity had the largest effect size η2 ( = .60). The results reveal a need to modify existing measures of integration; we recommend using questionnaires to measure behaviors that members of the majority would be willing to implement.

This article proposes the development of an intersectional life course perspective that is capable of exploring the links between structural inequalities and the lived experience of aging among racialized older people. Merging key concepts from intersectionality and life course perspectives, the authors suggest an analytic approach to better account for the connections between individual narratives and systems of domination that impinge upon the everyday lives of racialized older people. Our proposed intersectional life course perspective includes four dimensions: 1) identifying key events and their timing, 2) examining locally and globally linked lives, 3) exploring categories of difference and how they shape identities, 4) and assessing how processes of differentiation, and systems of domination shape the lives, agency and resistance among older people. Although applicable to various forms of marginalization, we examine the interplay of racialization, immigration, labour and care in later life to highlight relationships between systems, events, trajectories, and linked lives. The illustrative case example used in this paper emerged from a larger critical ethnographic study of aging in the Filipino community in Montreal, Canada. We suggest that an intersectional life course perspective has the potential to facilitate a deeper understanding of the nexus of structural, personal and relational processes that are experienced by diverse groups of older people across the life course and into late life.

A Boundary Property for Upper Domination
AbouEisha, Hassan M.
2016-08-08
An upper dominating set in a graph is a minimal (with respect to set inclusion) dominating set of maximum cardinality.The problem of finding an upper dominating set is generally NP-hard, but can be solved in polynomial time in some restricted graph classes, such as P4-free graphs or 2K2-free graphs.For classes defined by finitely many forbidden induced subgraphs, the boundary separating difficult instances of the problem from polynomially solvable ones consists of the so called boundary classes.However, none of such classes has been identified so far for the upper dominating set problem.In the present paper, we discover the first boundary class for this problem.

Full Text Available Dominance is referred to the level of influence that a person has in a conversation. Dominance is an important research area in social psychology, but the problem of its automatic estimation is a very recent topic in the contexts of social and wearable computing. In this paper, we focus on the dominance detection of visual cues. We estimate the correla¬tion among observers by categorizing the dominant people in a set of face-to-face conversations. Different dominance indicators from gestural communication are defined, manually annotated, and compared to the observers’ opinion. Moreover, these indicators are automatically extracted from video sequences and learnt by using binary classifiers. Results from the three analyses showed a high correlation and allows the categorization of dominant people in public discussion video sequences.

Frail and dependent older people in resource-poor settings are poorly served by health systems that lack outreach capacity. The COPE (Caring for Older PEople) multidimensional assessment tool is designed to help community health workers (CHWs) identify clinically significant impairments and deliver evidence-based interventions Older people (n = 150) identified by CHWs as frail or dependent, were assessed at home by the CHW using the structured COPE assessment tool, generating information on impairments in nutrition, mobility, vision, hearing, continence, cognition, mood and behaviour. The older people were reassessed by local physicians who reached a clinical judgment regarding the presence or absence of the same impairments based upon clinical examination guided by the EASY-Care assessment tool. The COPE tool was considered easy to administer, and gave CHWs a sense of empowerment to understand and act upon the needs of older people. Agreement between COPE assessment by CHW and clinician assessors was modest (ranged from 45.8 to 91.3 %) for most impairments. However, the prevalence of impairments was generally higher according to clinicians, particularly for visual impairment (98.7 vs 45.8 %), cognitive impairment (78.4 vs. 38.2 %) and depression (82.0 vs. 59.9 %). Most cases identified by WHO-COPE were clinician confirmed (positive predictive values - 72.2 to 98.5 %), and levels of disability and needs for care among those identified by COPE were higher than those additionally identified by the clinician alone. The COPE is a feasible tool for the identification of specific impairments in frail dependent older people in the community. Those identified are likely to be confirmed as having clinically relevant problems by clinicians working in the same service, and the COPE may be particularly effective at targeting attention upon those with the most substantial unmet needs.

Hand dominance in orthopaedic surgeons.
LENUS (Irish Health Repository)
Lui, Darren F
2012-08-01
Handedness is perhaps the most studied human asymmetry. Laterality is the preference shown for one side and it has been studied in many aspects of medicine. Studies have shown that some orthopaedic procedures had poorer outcomes and identified laterality as a contributing factor. We developed a questionnaire to assess laterality in orthopaedic surgery and compared this to an established scoring system. Sixty-two orthopaedic surgeons surveyed with the validated Waterloo Handedness Questionnaire (WHQ) were compared with the self developed Orthopaedic Handedness Questionnaire (OHQ). Fifty-eight were found to be right hand dominant (RHD) and 4 left hand dominant (LHD). In RHD surgeons, the average WHQ score was 44.9% and OHQ 15%. For LHD surgeons the WHQ score was 30.2% and OHQ 9.4%. This represents a significant amount of time using the non dominant hand but does not necessarily determine satisfactory or successful dexterity transferable to the operating room. Training may be required for the non dominant side.

This article describes interactive learning about independent living for people with disabilities and features the partnership of the College of Nursing and a Center for Independent Living (CIL). Using qualitative descriptive approach, students' written reflections were analyzed. Through "Xtreme Challenge," 82 undergraduate nursing students participated in aspects of independent living as well as identifying barriers. Students were engaged and learned to consider the person before the disability. Moreover, students valued the activity leaders' openness, which facilitated understanding the point of view of a person with disability. The value of partnership was evident as it allowed students to participate in active learning, which led to growth in the affective domain. Students became aware of potential education resources through the CIL. This article will guide educators in designing experiences that teach nursing care at the individual, family, and community level for people living with disabilities. © 2015 Association of Rehabilitation Nurses.

Full Text Available The ‘aging well’ discourse advances the idea of making older people responsible for their capability to stay healthy and active. In the context of an increased ageing population, which poses several challenges to countries’ government, this discourse has become dominant in Europe. We explore the way older people are visually represented on websites of organizations for older people in seven European countries (Finland, UK, the Netherlands, Spain, Italy, Poland and Romania, using an analytical approached based on visual content analysis, inspired by the dimensional model of national cultural differences from the Hofstede model (1991; 2001; 2011. We used two out of the five Hofstede dimensions: Individualism/Collectivism (IDV and Masculinity/Femininity (MAS. The results demonstrated that in all seven countries older people are mostly visually represented as healthy/active, which reflects a dominant ‘ageing well’ discourse in Europe. The results also demonstrated that in most cases older people tend to be represented together with others, which is not consonant with the dominant ‘ageing well’ discourse in Europe. A last finding was that the visual representation of older people is in about half of the cases in line with these Hofstede dimensions. We discuss the implications of these findings claiming that the ‘ageing well’ discourse might lead to ‘visual ageism’. Organizations could keep this in mind while using pictures for their website or in other media and consider to use various kind of pictures, or to avoid using pictures of older people that stigmatize, marginalize or injure. They could look into the cultural situatedness and intersectional character of age relations and consider alternative strategies of both visibility and invisibility to talk with and about our ageing societies.

Falls and near falls are common among people with Parkinson's (PwP). To date, most wearable sensor research focussed on fall detection, few studies explored if wearable sensors can detect instability. Can instability (caution or near-falls) be detected using wearable sensors in comparison to video analysis? Twenty-four people (aged 60-86) with and without Parkinson's were recruited from community groups. Movements (e.g. walking, turning, transfers and reaching) were observed in the gait laboratory and/or at home; recorded using clinical measures, video and five wearable sensors (attached on the waist, ankles and wrists). After defining 'caution' and 'instability', two researchers evaluated video data and a third the raw wearable sensor data; blinded to each other's evaluations. Agreement between video and sensor data was calculated on stability, timing, step count and strategy. Data was available for 117 performances: 82 (70%) appeared stable on video. Ratings agreed in 86/117 cases (74%). Highest agreement was noted for chair transfer, timed up and go test and 3 m walks. Video analysts noted caution (slow, contained movements, safety-enhancing postures and concentration) and/or instability (saving reactions, stopping after stumbling or veering) in 40/134 performances (30%): raw wearable sensor data identified 16/35 performances rated cautious or unstable (sensitivity 46%) and 70/82 rated stable (specificity 85%). There was a 54% chance that a performance identified from wearable sensors as cautious/unstable was so; rising to 80% for stable movements. Agreement between wearable sensor and video data suggested that wearable sensors can detect subtle instability and near-falls. Caution and instability were observed in nearly a third of performances, suggesting that simple, mildly challenging actions, with clearly defined start- and end-points, may be most amenable to monitoring during free-living at home. Using the genuine near-falls recorded, work continues to

An FFQ developed by the Center for Alaska Native Health Research for studies in Yup'ik people includes market foods and subsistence foods such as moose, seal, waterfowl and salmon that may be related to disease risk. Because the FFQ contains >100 food items, we sought to characterize dietary patterns more simply for use in ongoing pharmacogenomics studies. Exploratory factor analysis was used to derive a small number of 'factors' that explain a substantial amount of the variation in the Yup'ik diet. We estimated factor scores and measured associations with demographic characteristics and biomarkers. South-west Alaska, USA. Yup'ik people (n 358) aged ≥18 years. We identified three factors that each accounted for ≥10 % of the common variance: the first characterized by 'processed foods' (e.g. salty snacks, sweetened cereals); the second by 'fruits and vegetables' (e.g. fresh citrus, potato salad); and the third by 'subsistence foods' (seal or walrus soup, non-oily fish). Participants from coastal communities had higher values for the 'subsistence' factor, whereas participants from inland communities had higher values for the 'fruits and vegetables' factor. A biomarker of marine intake, δ 15N, was correlated with the 'subsistence' factor, whereas a biomarker of corn- and sugarcane-based market food intake, δ 13C, was correlated with 'processed foods'. The exploratory factor analysis identified three factors that appeared to reflect dietary patterns among Yup'ik based on associations with participant characteristics and biomarkers. These factors will be useful for chronic disease studies in this population.

On the Dominance of Attitude Emotionality.
Rocklage, Matthew D; Fazio, Russell H
2016-02-01
Many situations in our lives require us to make relatively quick decisions as whether to approach or avoid a person or object, buy or pass on a product, or accept or reject an offer. These decisions are particularly difficult when there are both positive and negative aspects to the object. How do people go about navigating this conflict to come to a summary judgment? Using the Evaluative Lexicon (EL), we demonstrate across three studies, 7,700 attitude expressions, and nearly 50 different attitude objects that when positivity and negativity conflict, the valence that is based more on emotion is more likely to dominate. Furthermore, individuals are also more consistent in the expression of their univalent summary judgments when they involve greater emotionality. In sum, valence that is based on emotion tends to dominate when resolving ambivalence and also helps individuals to remain consistent when offering quick judgments. © 2015 by the Society for Personality and Social Psychology, Inc.

Upper Domination: Towards a Dichotomy Through Boundary Properties
AbouEisha, Hassan M.
2017-07-14
An upper dominating set in a graph is a minimal dominating set of maximum cardinality. The problem of finding an upper dominating set is generally NP-hard. We study the complexity of this problem in finitely defined classes of graphs and conjecture that the problem admits a complexity dichotomy in this family. A helpful tool to study the complexity of an algorithmic problem is the notion of boundary classes. However, none of such classes has been identified so far for the upper dominating set problem. We discover the first boundary class for this problem and prove the dichotomy for monogenic classes.

Meeting the needs of the growing number of older people is a challenge for health and social care services. Home-based interventions aiming to modify health-related behaviours of frail older people have the potential to improve functioning and well-being. Previous reviews have focused on whether such interventions are effective, rather than what might make them effective. Recent advances in behavioural science make possible the identification of potential 'active ingredients' of effective interventions, such as component behaviour change techniques (BCTs), and intended intervention functions (IFs; e.g. to educate, to impart skills). This paper reports a protocol for a systematic review that seeks to (a) identify health behaviour change interventions for older frail people, (b) describe the content of these interventions, and (c) explore links between intervention content and effectiveness. The protocol is reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) 2015 guidelines. Studies will be identified through a systematic search of 15 electronic databases, supplemented by citation tracking. Studies will be retained for review where they report randomised controlled trials focusing on home-based health promotion delivered by a health professional for frail older people in community settings, written in English, and either published from 1980 onwards, or, for registered trials only, unpublished but completed with results obtainable from authors. Interventions will be coded for their content (BCTs, IFs) and for evidence of effectiveness (outcome data relating to behavioural and health outcomes). Analyses will describe characteristics of all interventions. Interventions for which effectiveness data are available will be categorised into those showing evidence of effectiveness versus those showing no such evidence. The potential for each intervention characteristic to contribute to change in behaviour or

Complex physically-based environmental models are being increasingly used as the primary tool for watershed planning and management due to advances in computation power and data acquisition. Model sensitivity analysis plays a crucial role in understanding the behavior of these complex models and improving their performance. Due to the non-linearity and interactions within these complex models, Global sensitivity analysis (GSA) techniques should be adopted to provide a comprehensive understanding of model behavior and identify its dominant controls. In this study we adopt a multi-basin multi-criteria GSA approach to systematically assess the behavior of the Modélisation Environmentale-Surface et Hydrologie (MESH) across various hydroclimatic conditions in Canada including areas in the Great Lakes Basin, Mackenzie River Basin, and South Saskatchewan River Basin. MESH is a semi-distributed physically-based coupled land surface-hydrology modelling system developed by Environment and Climate Change Canada (ECCC) for various water resources management purposes in Canada. We use a novel method, called Variogram Analysis of Response Surfaces (VARS), to perform sensitivity analysis. VARS is a variogram-based GSA technique that can efficiently provide a spectrum of sensitivity information across a range of scales within the parameter space. We use multiple metrics to identify dominant controls of model response (e.g. streamflow) to model parameters under various conditions such as high flows, low flows, and flow volume. We also investigate the influence of initial conditions on model behavior as part of this study. Our preliminary results suggest that this type of GSA can significantly help with estimating model parameters, decreasing calibration computational burden, and reducing prediction uncertainty.

Total Domination Versus Paired-Domination in Regular Graphs
Directory of Open Access Journals (Sweden)
Cyman Joanna
2018-05-01
Full Text Available A subset S of vertices of a graph G is a dominating set of G if every vertex not in S has a neighbor in S, while S is a total dominating set of G if every vertex has a neighbor in S. If S is a dominating set with the additional property that the subgraph induced by S contains a perfect matching, then S is a paired-dominating set. The domination number, denoted γ(G, is the minimum cardinality of a dominating set of G, while the minimum cardinalities of a total dominating set and paired-dominating set are the total domination number, γt(G, and the paired-domination number, γpr(G, respectively. For k ≥ 2, let G be a connected k-regular graph. It is known [Schaudt, Total domination versus paired domination, Discuss. Math. Graph Theory 32 (2012 435–447] that γpr(G/γt(G ≤ (2k/(k+1. In the special case when k = 2, we observe that γpr(G/γt(G ≤ 4/3, with equality if and only if G ≅ C5. When k = 3, we show that γpr(G/γt(G ≤ 3/2, with equality if and only if G is the Petersen graph. More generally for k ≥ 2, if G has girth at least 5 and satisfies γpr(G/γt(G = (2k/(k + 1, then we show that G is a diameter-2 Moore graph. As a consequence of this result, we prove that for k ≥ 2 and k ≠ 57, if G has girth at least 5, then γpr(G/γt(G ≤ (2k/(k +1, with equality if and only if k = 2 and G ≅ C5 or k = 3 and G is the Petersen graph.

This study tests specific competing hypotheses from social dominance theory/realistic conflict theory (RCT) versus system justification theory about the role of social status. In particular, it examines whether system justification belief and effects are stronger among people with low socioeconomic status, and in less socially developed and unequal nations than among better-off people and countries. A cross-national survey was carried out in 19 nations from the Americas, Western and Eastern Europe, Asia, and Oceania using representative online samples ( N = 14,936, 50.15% women, M age = 41.61 years). At the individual level, system justification beliefs, right-wing authoritarianism, social dominance orientation, national identification, sociopolitical conservatism, sex, age, and social status were measured. At the national level, the human development index and the Gini index were used. Multilevel analyses performed indicated that results fit better with the social dominance/RCT approach, as system justification was higher in high-status and developed nations; further, associations between legitimizing ideologies and system justification were stronger among high-status people.

Person-centered health and community health perspectives on its needs and resources are mandatory in healthcare policies in highly cultural diverse contexts. From this point of view, epidemiology needs to be centered not only on the disease, but also on the health diagnosis and its context, including the points of view of people and the community about their problems and needs. This article describes and qualitatively analyzes the views of adults with self-identified mental health disorders (MHD) in rural regions on the coast, highlands, and jungle of Peru, as causal factors, personal resources, and healthcare expectations from health facilities, using the narrative approach of ideographic formulation proposed by the World Psychiatric Association. The database of mental health epidemiological studies from the National Mental Health Institute was used. The qualitative analysis on answers from 235 people reveals that a large part of MHD is linked to the dynamics of troubled families and to the loss of loved ones. The presence of scarce community resources that help overcome these problems is noted. Counseling is stressed among the expectations of healthcare at facilities; nevertheless, many people do not know what to expect from such healthcare. We believe that the narrative approach is an important tool as regards to community- and person-centered medicine and intervention strategy planning.

Purpose To study the phenotype in two families with genetically identified autosomal dominant retinitis pigmentosa (adRP) focusing on macular structure and function. Methods Clinical data were collected at the Department of Ophthalmology, Lund University, Sweden, for affected and unaffected family members from two pedigrees with adRP. Examinations included optical coherence tomography (OCT), full-field electroretinography (ffERG), and multifocal electroretinography (mfERG). Molecular genetic screening was performed for known mutations associated with adRP. Results The mode of inheritance was autosomal dominant in both families. The members of the family with a mutation in the PRPF31 (p.IVS6+1G>T) gene had clinical features characteristic of RP, with severely reduced retinal rod and cone function. The degree of deterioration correlated well with increasing age. The mfERG showed only centrally preserved macular function that correlated well with retinal thinning on OCT. The family with a mutation in the RHO (p.R135W) gene had an extreme intrafamilial variability of the phenotype, with more severe disease in the younger generations. OCT showed pathology, but the degree of morphological changes was not correlated with age or with the mfERG results. The mother, with a de novo mutation in the RHO (p.R135W) gene, had a normal ffERG, and her retinal degeneration was detected merely with the reduced mfERG. Conclusions These two families demonstrate the extreme inter- and intrafamilial variability in the clinical phenotype of adRP. This is the first Swedish report of the clinical phenotype associated with a mutation in the PRPF31 (p.IVS6+1G>T) gene. Our results indicate that methods for assessment of the central retinal structure and function may improve the detection and characterization of the RP phenotype. PMID:27212874

When Inequality Fails: Power, Group Dominance, and Societal Change
Directory of Open Access Journals (Sweden)
Felicia Pratto
2013-12-01
Full Text Available Social dominance theory was developed to account for why societies producing surplus take and maintain the form of group-based dominance hierarchies, in which at least one socially-constructed group has more power than another, and in which men are more powerful than women and adults more powerful than children. Although the theory has always allowed for societies to differ in their severity of group-based dominance and how it is implemented, it has predicted that alternative forms of societal organization will occur rarely and not last. This paper revisits aspects of the theory that allow for the possibility of societal alternatives and change. We also consider boundary conditions for the theory, and whether its current theoretical apparatus can account for societal change. By expanding the typical three-level dynamic system to describe societies (micro-meso-macro into four levels (including meta to consider how societies relate to one another, we identify political tensions that are unstable power structures rather than stable hierarchies. In research on institutions, we identify smaller-scale alternative forms of social organization. We identify logical, empirical, and theoretical shortcomings in social dominance theory’s account of stability and change, consider alternative forms of social organization, and suggest fruitful avenues for theoretical extension.

People with SCI in Vietnam had significantly higher general life satisfaction than participants in India and Sri Lanka. Significant differences were identified in several demographic and life situation variables among the three Asian countries. With regard to "Traditional", "Universal", and "Personal" life values significant differences among three participating countries were identified in all domains. No significant relationships were identified between life satisfaction and life values for people with SCI in India, Vietnam, or Sri Lanka. It could be presumed that particular demographic and life situation variables are more powerful factors of life satisfaction following SCI than the dominant culture of a country expressed by life values.

Analysis of U.S. census data provides evidence that decreased labor force participation of older people, 1980 to 1970, was due to the disproportionate growth in numbers of persons aged 65 or older and the growing economic dominance of industries that provide relatively few opportunities for older people's participation.

Does Social Media Benefit Dominant or Alternative Water Discourses?
Directory of Open Access Journals (Sweden)
María Mancilla-García
2015-06-01
Full Text Available Political ecology and cognate fields have highlighted the social constructedness of different water discourses, exposing them as the product of a particular view of nature with underpinning interests and political consequences. Integrated Water Resources Management, technical approaches, or the privatisation of drinking water services have enjoyed dominant positions, being able to determine what constitutes common sense. This has excluded numerous other alternative approaches, such as those championed by indigenous peoples. Social media, through its easy accessibility and its emphasis on visual, interactive, and short communication forms, bears the promise to challenge dominant discourses. Whether social media benefits dominant or alternative discourses has not yet been explored by the political ecology literature to which this article contributes. The article conducts a qualitative analysis of the use of two of the main social networking services (Facebook and Twitter by nine organisations working on water. Organisations were selected considering their likelihood to champion different water discourses. The article analyses the formats used, the place of communities, and the kind of language employed. It argues that while social media presents an interesting potential for alternative discourses, it also offers important tools for dominant discourses to consolidate themselves. The article concludes that social media does not structurally challenge the status quo and suggests avenues for future research.

The positive and negative framing of affirmative action: a group dominance perspective.
Haley, Hillary; Sidanius, Jim
2006-05-01
Using a sample of 328 White, Latino, and Black Los Angeles County adults, the authors examined the tendency to employ various affirmative action "frames" (e.g., affirmative action as a "tie-breaking" device or as a quota-based policy). All three groups agreed about which frames cast affirmative action in a positive light and which cast it in a negative light. Although minorities had a tendency to frame affirmative action in terms that most people find morally acceptable, Whites had a tendency to frame affirmative action in terms most people find unacceptable. In addition, compared to minorities, Whites were less supportive of affirmative action regardless of how it was framed. LISREL modeling also was employed to test two competing models regarding predictors of the tendency to use frames that one personally finds to be relatively negative versus positive. Consistent with the expectations of social dominance theory and a motivated cognition perspective, the authors found that social dominance orientation (SDO) had significant net direct and indirect effects on one's framing of affirmative action.

Faces automatically draw attention, allowing rapid assessments of personality and likely behaviour. How we respond to people is, however, highly dependent on whether we know who they are. According to face processing models person knowledge comes from an extended neural system that includes structures linked to episodic memory. Here we use scalp recorded brain signals to demonstrate the specific role of episodic memory processes during face processing. In two experiments we recorded Event-Related Potentials (ERPs) while participants made identify, familiar or unknown responses to famous faces. ERPs revealed neural signals previously associated with episodic recollection for identify but not familiar faces. These findings provide novel evidence suggesting that recollection is central to face processing, providing one source of person knowledge that can be used to moderate the initial impressions gleaned from the core neural system that supports face recognition.

The dominance behavioral system has been conceptualized as a biologically based system comprising motivation to achieve social power and self-perceptions of power. Biological, behavioral, and social correlates of dominance motivation and self-perceived power have been related to a range of psychopathological tendencies. Preliminary evidence suggests that mania and risk for mania (manic temperament) relate to the dominance system. Four studies examine whether manic temperament, measured with the Hypomanic Personality Scale (HPS), is related to elevations in dominance motivation, self-perceptions of power, and engagement in socially dominant behavior across multiple measures. In Study 1, the HPS correlated with measures of dominance motivation and the pursuit of extrinsically-oriented ambitions for fame and wealth among 454 undergraduates. In Study 2, the HPS correlated with perceptions of power and extrinsically-oriented lifetime ambitions among 780 undergraduates. In Study 3, the HPS was related to trait-like tendencies to experience hubristic (dominance-related) pride, as well as dominance motivation and pursuit of extrinsically-oriented ambitions. In Study 4, we developed the Socially Dominant Behavior Scale to capture behaviors reflecting high power. The scale correlated highly with the HPS among 514 undergraduates. The studies rely on self-ratings of manic temperament and dominance constructs, and findings have not yet been generalized to a clinical sample. Taken together, results support the hypothesis that manic temperament is related to a focus on achieving social dominance, ambitions related to achieving social recognition, perceptions of having achieved power, tendencies to experience dominance-related pride, and engagement in social behaviors consistent with this elevated sense of power.

It is unknown if people who consider themselves as active have the ability to identify what is considered moderate intensity. Methods: Fifty-one participants who reported achieving a minimum 150 minutes per week at a minimum of moderate intensity PA were recruited through a local fitness facility. All participants underwent a single assessment involving questionnaires, clinical measures, and a treadmill test to measure the ability to perceive moderate intensity. Following the visit, participants' PA level was evaluated by heart rate monitor, while exercising, for 7 consecutive days. Results: Eighty percent of participants overestimated moderate intensity on the treadmill test; they were at vigorous intensity compared to what is considered moderate. Only 11.8% of participants accurately identified moderate intensity; all of them were women (P=0.03, had a high level of education (P=0.04, and knew that moderate intensity was the minimum intensity recommended by health organizations (P<0.01. Only 69.2% of participants reached the aerobic component of the International Physical Activity Guidelines with no significant advantage for those correctly identifying moderate intensity.

The aim of this research was to explore nurses' perceptions of the attributes of quality care and the factors that facilitate or hinder high-quality nursing care in long-term care. The quality of care for older people living in long-term care has been identified as an issue of concern in many nursing research studies. While many factors have been identified, it is difficult to determine key factors from current research. The study was a qualitative exploration of nurses' perceptions of quality care for older people and the factors that facilitate or hinder quality care. It involved 20 interviews with nurses. Respondents were asked to illustrate their accounts with examples from practice. This phase of the research was guided by the principles of hermeneutic phenomenology and the analysis process by Van Manen. The findings indicated that nurses perceived quality care for older people in Ireland as holistic, individualized and focused on promoting independence and choice. The research revealed, however, that care in many practice areas was not individualized, patient choice and involvement in decision making was limited and some areas engendered dependency. While staffing was identified as a factor which had an impact on the provision of patient choice, other issues, such as the motivation of staff, the role of the ward manager and the dominance of routine were also highlighted. There is a need to review organizational approaches to care, develop patient centred approaches to care and provide educational support for managers. This research focuses on care for older people; it helps practitioners identify key factors in the provision of quality care for older people living in long-term care.

As the only connecting term between water balance and energy budget in the earth-atmospheric system, evapotranspiration (ET) is considered the most excellent indicator for the activity for the water and energy cycle. Under the background of global change, regional ET estimates, components partitioning as well as their spatial and temporal patterns recognition are of great importance in understanding the hydrological processes and improving water management practices. This is particularly true for the Tibetan Plateau (TP), one of most sensitive and vulnerable region in response to the environment change in the earth. In this study, with flux site observation data and monthly ET data from the monthly water balance method incorporating the terrestrial water storage changes from the Gravity Recovery and Climate Experiment satellite (GRACE) production as the multiple validations, the long-term daily ET in the TP was retrieved by a modified Penman-Monteith-Leuning (PML) model with considering evapotranspiration over snow covered area during 1982-2012. The spatial and temporal changes of partitioned three components of ET, i.e., soil evaporation (Es), transpiration through the stomata of plant (Ec) and canopy interception (Ei), were investigated in the TP. Meanwhile, how the ET components contribute to ET changes and respond to the change in environmental factors in the TP was revealed and discussed. The results indicate that Es dominates ET in most areas of the TP with the mean annual ratio of 65.7%, except southeastern regions where the vegetation coverage is high. Although regional average ET and three main components all present obvious increase trends during the past decades, high spatial heterogeneity for their trends are identified in the TP. Moreover, a mixed changing pattern can be apparently found for Es in southeastern area, Ec and Ei in northwestern and southeastern area. Spatially, the ET variation are mainly attributed to change in Es, followed by Ec and Ei

Relating 2-Rainbow Domination To Roman Domination

Full Text Available For a graph G, let R(G and yr2(G denote the Roman domination number of G and the 2-rainbow domination number of G, respectively. It is known that yr2(G ≤ R(G ≤ 3/2yr2(G. Fujita and Furuya [Difference between 2-rainbow domination and Roman domination in graphs, Discrete Appl. Math. 161 (2013 806-812] present some kind of characterization of the graphs G for which R(G − yr2(G = k for some integer k. Unfortunately, their result does not lead to an algorithm that allows to recognize these graphs efficiently. We show that for every fixed non-negative integer k, the recognition of the connected K4-free graphs G with yR(G − yr2(G = k is NP-hard, which implies that there is most likely no good characterization of these graphs. We characterize the graphs G such that yr2(H = yR(H for every induced subgraph H of G, and collect several properties of the graphs G with R(G = 3/2yr2(G.

The paired-domination and the upper paired-domination numbers of graphs

Full Text Available In this paper we continue the study of paired-domination in graphs. A paired-dominating set, abbreviated PDS, of a graph \\(G\\ with no isolated vertex is a dominating set of vertices whose induced subgraph has a perfect matching. The paired-domination number of \\(G\\, denoted by \\(\\gamma_{p}(G\\, is the minimum cardinality of a PDS of \\(G\\. The upper paired-domination number of \\(G\\, denoted by \\(\\Gamma_{p}(G\\, is the maximum cardinality of a minimal PDS of \\(G\\. Let \\(G\\ be a connected graph of order \\(n\\geq 3\\. Haynes and Slater in [Paired-domination in graphs, Networks 32 (1998, 199-206], showed that \\(\\gamma_{p}(G\\leq n-1\\ and they determine the extremal graphs \\(G\\ achieving this bound. In this paper we obtain analogous results for \\(\\Gamma_{p}(G\\. Dorbec, Henning and McCoy in [Upper total domination versus upper paired-domination, Questiones Mathematicae 30 (2007, 1-12] determine \\(\\Gamma_{p}(P_n\\, instead in this paper we determine \\(\\Gamma_{p}(C_n\\. Moreover, we describe some families of graphs \\(G\\ for which the equality \\(\\gamma_{p}(G=\\Gamma_{p}(G\\ holds.

Social dominance and ethical ideology: the end justifies the means?
Wilson, Marc Stewart
2003-10-01
Although many social psychological researchers have tried to identify the antecedents of unethical or immoral behavior, investigators have little considered the content of ethical beliefs that associate with important personality variables such as authoritarianism (B. Altemeyer, 1981, 1996) and social dominance orientation (SDO; J. Sidanius, 1993). Previous studies suggest that authoritarianism is associated with the rejection of relativistic standards for moral actions and--to a lesser extent--the idealistic belief that moral actions should not harm others (J. W. McHoskey, 1996). In the present study, 160 New Zealand University students completed measures of SDO (J. Sidanius), Right Wing Authoritarianism (RWA, B. Altemeyer, 1981), and two subscales of ethical ideology: Relativism and Idealism (D. R. Forsyth, 1980). As expected, SDO showed a negative relationship with Idealism, a belief that actions should not harm others. But, contrary to expectations, SDO showed no consistent association with relativism, a belief that the moralities of actions are not comparable. On the basis of those findings, people with high SDO might be described as "ruthless" in their pursuit of desirable goals and are indifferent about whether the morality of different actions can be compared or even matter.

Dominating biological networks.
Directory of Open Access Journals (Sweden)
Tijana Milenković
Full Text Available Proteins are essential macromolecules of life that carry out most cellular processes. Since proteins aggregate to perform function, and since protein-protein interaction (PPI networks model these aggregations, one would expect to uncover new biology from PPI network topology. Hence, using PPI networks to predict protein function and role of protein pathways in disease has received attention. A debate remains open about whether network properties of "biologically central (BC" genes (i.e., their protein products, such as those involved in aging, cancer, infectious diseases, or signaling and drug-targeted pathways, exhibit some topological centrality compared to the rest of the proteins in the human PPI network.To help resolve this debate, we design new network-based approaches and apply them to get new insight into biological function and disease. We hypothesize that BC genes have a topologically central (TC role in the human PPI network. We propose two different concepts of topological centrality. We design a new centrality measure to capture complex wirings of proteins in the network that identifies as TC those proteins that reside in dense extended network neighborhoods. Also, we use the notion of domination and find dominating sets (DSs in the PPI network, i.e., sets of proteins such that every protein is either in the DS or is a neighbor of the DS. Clearly, a DS has a TC role, as it enables efficient communication between different network parts. We find statistically significant enrichment in BC genes of TC nodes and outperform the existing methods indicating that genes involved in key biological processes occupy topologically complex and dense regions of the network and correspond to its "spine" that connects all other network parts and can thus pass cellular signals efficiently throughout the network. To our knowledge, this is the first study that explores domination in the context of PPI networks.

Extrinsic versus intrinsic hand muscle dominance in finger flexion.
Al-Sukaini, A; Singh, H P; Dias, J J
2016-05-01
This study aims to identify the patterns of dominance of extrinsic or intrinsic muscles in finger flexion during initiation of finger curl and mid-finger flexion. We recorded 82 hands of healthy individuals (18-74 years) while flexing their fingers and tracked the finger joint angles of the little finger using video motion tracking. A total of 57 hands (69.5%) were classified as extrinsic dominant, where the finger flexion was initiated and maintained at proximal interphalangeal and distal interphalangeal joints. A total of 25 (30.5%) were classified as intrinsic dominant, where the finger flexion was initiated and maintained at the metacarpophalangeal joint. The distribution of age, sex, dominance, handedness and body mass index was similar in the two groups. This knowledge may allow clinicians to develop more efficient rehabilitation regimes, since intrinsic dominant individuals would not initiate extrinsic muscle contraction till later in finger flexion, and might therefore be allowed limited early active motion. For extrinsic dominant individuals, by contrast, initial contraction of extrinsic muscles would place increased stress on the tendon repair site if early motion were permitted. © The Author(s) 2016.

Full Text Available Primary open-angle glaucoma (POAG is a clinically important and genetically heterogeneous cause of progressive vision loss as a result of retinal ganglion cell death. Here we have utilized trio-based, whole-exome sequencing to identify the genetic defect underlying an autosomal dominant form of adult-onset POAG segregating in an African-American family. Exome sequencing identified a novel missense variant (c.418C>T, p.Arg140Trp in exon-5 of the gene coding for epidermal growth factor (EGF containing fibulin-like extracellular matrix protein 1 (EFEMP1 that co-segregated with disease in the family. Linkage and haplotype analyses with microsatellite markers indicated that the disease interval overlapped a known POAG locus (GLC1H on chromosome 2p. The p.Arg140Trp substitution was predicted in silico to have damaging effects on protein function and transient expression studies in cultured cells revealed that the Trp140-mutant protein exhibited increased intracellular accumulation compared with wild-type EFEMP1. In situ hybridization of the mouse eye with oligonucleotide probes detected the highest levels of EFEMP1 transcripts in the ciliary body, cornea, inner nuclear layer of the retina, and the optic nerve head. The recent finding that a common variant near EFEMP1 was associated with optic nerve-head morphology supports the possibility that the EFEMP1 variant identified in this POAG family may be pathogenic.

Brain lateralization is a common term used to describe dominance of one brain hemisphere over another for a specific function. The right hand dominance in writing, controlled by the left hemisphere, is preceded by development of communicative gesticulation and followed by development of speech in the same hemisphere. We assumed that some people are not aware of their own capability of using the other hand for tasks involving fine motor sequential movements. To prove this hypothesis, the participants were asked to perform one trained task (writing) and one less-trained task (drawing) with a dominant and a non-dominant hand. The final sample was comprised of 1189 children from 14 elementary schools and 8 high schools in the Osijek area, of which 685 elementary school children were attending 1st to 4th grade and 504 high school children were attending 3rd and 4th grade. The participants were asked to write two words, draw a specific object (a vase with flowers) and fill out a questionnaire with 10 questions concerning the classification of handedness and cerebral hemisphere dominance. The self-reported cerebral lateralization assessed in the questionnaire was compared with the drawing and the writing performance. The self-reported and objectively measured hand dominance deviated in the cases of the ambidextrous who consider themselves right-handers. Given the fact that the number of ambidextrous persons was greater in elementary schools than in high schools, we concluded how training of the right hand decreases the ability of using both hands equally for either of the tested functions - writing and drawing.

Learning preferences and attitudes by multi-criteria overlap dominance and relevance functions
DEFF Research Database (Denmark)
Franco de los Ríos, Camilo; Hougaard, Jens Leth; Nielsen, Kurt
2018-01-01
This paper proposes an interval-valued multi-criteria method for learning preferences and attitudes, identifying priorities with maximal robustness for decision support. The method is based on the notion of weighted overlap dominance, formalized by means of aggregation operators and interval......-valued fuzzy sets. The procedure handles uncertainty by estimating the likelihood of dominance among pairs of alternatives, inducing an attitude-based system of dominance and indifference relations. This system allows conflicting situations of indifference/dependency to arise, which need to be resolved...... for properly identifying preferences under any attitude. In order to do so, relevance functions are examined over the whole system of relations, obtaining a weak preference order together with its associated attitude and robustness index. As a result, the proposed method allows learning preferences...

Describing the organization of dominance relationships by dominance-directed tree method.
Izar, Patrícia; Ferreira, Renata G; Sato, Takechi
2006-02-01
Methods to describe dominance hierarchies are a key tool in primatology studies. Most current methods are appropriate for analyzing linear and near-linear hierarchies; however, more complex structures are common in primate groups. We propose a method termed "dominance-directed tree." This method is based on graph theory and set theory to analyze dominance relationships in social groups. The method constructs a transitive matrix by imposing transitivity to the dominance matrix and produces a graphical representation of the dominance relationships, which allows an easy visualization of the hierarchical position of the individuals, or subsets of individuals. The method is also able to detect partial and complete hierarchies, and to describe situations in which hierarchical and nonhierarchical principles operate. To illustrate the method, we apply a dominance tree analysis to artificial data and empirical data from a group of Cebus apella. Copyright 2006 Wiley-Liss, Inc.

Praise for regret: People value regret above other negative emotions
Saffrey, Colleen; Summerville, Amy; Roese, Neal J.
2008-01-01
What do people think about the emotion of regret? Recent demonstrations of the psychological benefits of regret have been framed against an assumption that most people find regret to be aversive, both when experienced but also when recalled later. Two studies explored lay evaluations of regret experiences, revealing them to be largely favorable rather than unfavorable. Study 1 demonstrated that regret, but not other negative emotions, was dominated by positive more than negative evaluations. ...

The objective of this systematic review was to identify primary health-care or aged-care strategies that have or could support the well-being of older Indigenous peoples. A search was undertaken of primary databases including Medical Literature Analysis and Retrieval System Online and Cumulative Index to Nursing and Allied Health Literature. Papers which reported on the perspectives of older Indigenous peoples, community members and provider participants were included. Findings were pooled using a meta-aggregative approach. Three high-level synthesised findings - maintaining Indigenous identity, promoting independence and delivering culturally safe care - were believed to be important for supporting the well-being of older Indigenous peoples. As physical independence often diminishes with age, having the support of culturally safe primary health-care and aged-care services that understand the importance of maintaining an Indigenous identity and promoting independence will be crucial for the well-being of older Indigenous peoples. © 2016 AJA Inc.

The dominance behavioral system has been conceptualized as a biologically based system comprising motivation to achieve social power and self-perceptions of power. Biological, behavioral, and social correlates of dominance motivation and self-perceived power have been related to a range of psychopathological tendencies. Preliminary evidence suggests that mania and risk for mania (manic temperament) relate to the dominance system.

Full Text Available Problem Statement. Teaching style is the expression (form of expression of preferred behavioral modalities who return with some regularity in the work of teacher (E.Geissler, Purpose of Study. The intention of this paper is to identify a pattern of expression interact between two dimensions-professional of primary school teachers: the dominant teaching style and the dominant authority type of each teacher. I opted for a classification according to the particular act of communication: emotional-improvising style, emotional-methodical style, rational-improvising style and rational-methodical style. Methods. To identify the dominant teaching style was built a questionnaire consisting of 16 questions. The second questionnaire was proposed for a self-evaluative kind of authority expressed in the daily professional work. To identify the dominant type of authority were updated two classifications: traditional axis authoritarian - democratic - laissez-faire and a classification inspired by John RP French and B. Raven expert authority, rewards, position and personal. In this investigation were involved 30 teachers for primary education. Findings and Results. Exists a moderate correlation between rational-improvising style and authoritarian and position styles of authority. Also, indicates significant statistical connection between rational-improviser teaching style and authoritarian, democratic and expert teacher’s authority. The indexes indicate statistical connections moderate correlation between rational-methodical style and personal authority. The indexes of correlation indicates significant statistical link between emotional-improvisational style teaching styles and reward and expert authority. The indexes indicate statistical connections moderate correlation between emotional-style improvisation and styles of authority laissez-faire, and his model.

A New Algorithm Using the Non-Dominated Tree to Improve Non-Dominated Sorting.
Gustavsson, Patrik; Syberfeldt, Anna
2018-01-01
Non-dominated sorting is a technique often used in evolutionary algorithms to determine the quality of solutions in a population. The most common algorithm is the Fast Non-dominated Sort (FNS). This algorithm, however, has the drawback that its performance deteriorates when the population size grows. The same drawback applies also to other non-dominating sorting algorithms such as the Efficient Non-dominated Sort with Binary Strategy (ENS-BS). An algorithm suggested to overcome this drawback is the Divide-and-Conquer Non-dominated Sort (DCNS) which works well on a limited number of objectives but deteriorates when the number of objectives grows. This article presents a new, more efficient algorithm called the Efficient Non-dominated Sort with Non-Dominated Tree (ENS-NDT). ENS-NDT is an extension of the ENS-BS algorithm and uses a novel Non-Dominated Tree (NDTree) to speed up the non-dominated sorting. ENS-NDT is able to handle large population sizes and a large number of objectives more efficiently than existing algorithms for non-dominated sorting. In the article, it is shown that with ENS-NDT the runtime of multi-objective optimization algorithms such as the Non-Dominated Sorting Genetic Algorithm II (NSGA-II) can be substantially reduced.

Taking performance-enhancing drugs (PEDs) can cause serious and irreversible health consequences, which can ultimately lead to premature death. Some young people may take PEDs without fully understanding the ramifications of their actions or based on the advice from others. The purpose of this systematic review was to identify the main factors that predicted doping among young people. The literature was systematically reviewed using search engines, manually searching specialist journals, and pearl growing. Fifty-two studies, which included 187,288 young people aged between 10 and 21 years of age, 883 parents of adolescent athletes, and 11 adult coaches, who were interviewed regarding young athletes, were included in this review. Nine factors predicted doping among young people: gender; age; sports participation; sport type; psychological variables; entourage; ethnicity; nutritional supplements; and health harming behaviors. In regards to psychological variables, 22 different constructs were associated with doping among young people. Some psychological constructs were negatively associated with doping (e.g., self-esteem, resisting social pressure, and perfectionist strivings), whereas other were positively associated with doping (e.g., suicide risk, anticipated regret, and aggression). Policy makers and National Anti-Doping Organizations could use these findings to help identify athletes who are more at risk of doping and then expose these individuals to anti-doping education. Based on the current findings, it also appears that education programs should commence at the onset of adolescence or even late childhood, due to the young age in which some individuals start doping.

Full Text Available Background: International Classification of Diseases, 10th Revision codes (ICD-10 for autosomal dominant polycystic kidney disease (ADPKD is used within several administrative health care databases. It is unknown whether these codes identify patients who meet strict clinical criteria for ADPKD. Objective: The objective of this study is (1 to determine whether different ICD-10 coding algorithms identify adult patients who meet strict clinical criteria for ADPKD as assessed through medical chart review and (2 to assess the number of patients identified with different ADPKD coding algorithms in Ontario. Design: Validation study of health care database codes, and prevalence. Setting: Ontario, Canada. Patients: For the chart review, 201 adult patients with hospital encounters between April 1, 2002, and March 31, 2014, assigned either ICD-10 codes Q61.2 or Q61.3. Measurements: This study measured positive predictive value of the ICD-10 coding algorithms and the number of Ontarians identified with different coding algorithms. Methods: We manually reviewed a random sample of medical charts in London, Ontario, Canada, and determined whether or not ADPKD was present according to strict clinical criteria. Results: The presence of either ICD-10 code Q61.2 or Q61.3 in a hospital encounter had a positive predictive value of 85% (95% confidence interval [CI], 79%-89% and identified 2981 Ontarians (0.02% of the Ontario adult population. The presence of ICD-10 code Q61.2 in a hospital encounter had a positive predictive value of 97% (95% CI, 86%-100% and identified 394 adults in Ontario (0.003% of the Ontario adult population. Limitations: (1 We could not calculate other measures of validity; (2 the coding algorithms do not identify patients without hospital encounters; and (3 coding practices may differ between hospitals. Conclusions: Most patients with ICD-10 code Q61.2 or Q61.3 assigned during their hospital encounters have ADPKD according to the clinical

Full Text Available A variant in a transcription factor gene, POU4F3, is responsible for autosomal dominant nonsyndromic hereditary hearing loss, DFNA15. To date, 14 variants, including a whole deletion of POU4F3, have been reported to cause HL in various ethnic groups. In the present study, genetic screening for POU4F3 variants was carried out for a large series of Japanese hearing loss (HL patients to clarify the prevalence and clinical characteristics of DFNA15 in the Japanese population. Massively parallel DNA sequencing of 68 target candidate genes was utilized in 2,549 unrelated Japanese HL patients (probands to identify genomic variations responsible for HL. The detailed clinical features in patients with POU4F3 variants were collected from medical charts and analyzed. Novel 12 POU4F3 likely pathogenic variants (six missense variants, three frameshift variants, and three nonsense variants were successfully identified in 15 probands (2.5% among 602 families exhibiting autosomal dominant HL, whereas no variants were detected in the other 1,947 probands with autosomal recessive or inheritance pattern unknown HL. To obtain the audiovestibular configuration of the patients harboring POU4F3 variants, we collected audiograms and vestibular symptoms of the probands and their affected family members. Audiovestibular phenotypes in a total of 24 individuals from the 15 families possessing variants were characterized by progressive HL, with a large variation in the onset age and severity with or without vestibular symptoms observed. Pure-tone audiograms indicated the most prevalent configuration as mid-frequency HL type followed by high-frequency HL type, with asymmetry observed in approximately 20% of affected individuals. Analysis of the relationship between age and pure-tone average suggested that individuals with truncating variants showed earlier onset and slower progression of HL than did those with non-truncating variants. The present study showed that variants

Drowning is a major public health issue, with risk increasing during times of flood. Driving though floodwater is a major risk factor for flood-related drowning and injury, and despite widespread public health campaigns, many people continue to undertake this risky behaviour and require rescue. We aimed to identify key challenges faced by emergency services personnel when rescuing those who have driven into floodwater, and to identify strategies for supporting rescuers in this important role. Australian flood rescue operators (N=8) who had previously rescued a driver who had driven through floodwater, participated in semi-structured interviews. Data were analysed using thematic analysis. Four challenges emerged from their experiences: Involvement of untrained personnel, varying information provided by emergency telephone operators, behaviour of drivers complicating the rescue, people sightseeing floods or flood rescues, or ignoring closed roads providing sources of distraction and frustration. We propose five strategies for translating these results into practice, including: training and protocol development for (1) emergency personnel and (2) telephone operators, (3) training for rescuers regarding non-compliant rescuees, (4) educating the public, and (5) increasing compliance with closed roads. Current findings provide valuable insights into how rescuers can be supported in performing their roles, and implementation of these strategies has the potential to reduce fatalities occurring due to driving through floodwater. SO WHAT?: The strategies presented have the potential to reduce the frequency and improve the outcomes of floodwater rescues, aiding in the prevention of injury and death.

As teenagers have easy access to both radio programs and cell phones, the current study used these tools so that young people could anonymously identify questions about sex and other related concerns in the urban environment of the Democratic Republic of Congo. The purpose of this healthcare intervention was to identify and address concerns raised by young people, which are related to sexual health, and which promote youth health. This healthcare intervention was conducted over a six month period and consisted of a survey carried out in Kinshasa. This focused on 14 to 24 old young people using phone calls on a radio program raising concerns related to sexuality. The radio program was jointly run by a journalist and a health professional who were required to reply immediately to questions from young people. All sexual health concerns were recorded and analyzed. Forty programs were broadcast in six months and 1,250 messages and calls were recorded: 880 (70%) from girls and 370 (30%) from boys, which represents an average of 32 interventions (of which 10 calls and 22 messages) per broadcast. Most questions came from 15-19- and 20-24-year-old girls and boys. Focus of girls' questions: menstrual cycle calculation and related concerns accounted for the majority (24%); sexual practices (16%), love relationships (15%) and virginity (14%). Boys' concerns are masturbation (and its consequences) (22%), sexual practices (19%), love relationships (18%) and worries about penis size (10%). Infections (genital and STI) and topics regarding HIV represent 9% and 4% of the questions asked by girls against 7% and 10% by boys. Concerns were mainly related to knowledge, attitudes and competences to be developed. Concerns and sexual practices raised by teens about their sexual and emotional life have inspired the design of a practical guide for youth self-training and have steered the second phase of this interactive program towards supporting their responsible sexuality.

Some of the needs that people with dementia and their informal carers currently perceive as insufficiently met by regular care and support services might be alleviated, or even be met, using modern Information and Communication Technology (ICT). The study described in this chapter was designed to provide an insight into the state of the art in ICT solutions that could contribute to meet the most frequently mentioned unmet needs by people with dementia and their informal carers. These needs can be summarized as (1) the need for general and personalized information; (2) the need for support with regard to symptoms of dementia; (3) the need for social contact and company; and (4) the need for health monitoring and perceived safety. Databases that were searched include PubMed, Cinahl, Psychinfo, Google (Scholar), INSPEC and IEEE. In total 22 websites and 46 publications were included that satisfied the following criteria: the article reports on people with dementia and/or their informal carers and discusses an ICT device that has been tested within the target group and has proven to be helpful. Within the first need area 18 relevant websites and three studies were included; within the second need area 4 websites and 20 publications were included. Within the third and fourth need area 11 and 12 publications were included, respectively. Most articles reported on uncontrolled studies. It is concluded that the informational websites offer helpful information for carers but seem less attuned to the person with dementia and do not offer personalized information. ICT solutions aimed at compensating for disabilities, such as memory problems and daily activities, demonstrate that people with mild to moderate dementia are capable of handling simple electronic equipment and can benefit from it in terms of more confidence and enhanced positive affect. Instrumental ICT support for coping with behavioural and psychological changes in dementia is relatively disregarded as yet, while

Attitudes toward group-based inequality: social dominance or social identity?
Schmitt, Michael T; Branscombe, Nyla R; Kappen, Diane M
2003-06-01
In five studies we explored how the context in which people think about the social structure and the implications of the social structure for one's in-group affect attitudes toward inequality. In Studies 1 and 2 we found that social dominance orientation (SDO) scores reflect attitudes toward specific types of inequality that are salient in context. Consistent with social identity theory, in Studies 3 to 5 we found that SDO scores reflected the interests of specific group identities. Indeed, when we compared existing privileged and disadvantaged groups, and when we manipulated in-group status, we found that participants held more positive attitudes toward inequality when the in-group was privileged, compared to when the in-group was disadvantaged. Across all of our studies, results were consistent with the contention that attitudes toward inequality are group-specific and depend on the social-structural position of salient in-groups. We discuss the implications of our findings for social dominance theory.

2018-05-01
Most dendroecological studies focus on dominant trees, but little is known about the growing season of trees belonging to different size classes and their sensitivity to biotic factors. The objective of this study was to compare the dynamics of xylem formation between dominant and suppressed trees of Abies fabri of similar age growing in the Gongga Mountains, southeastern Tibetan Plateau, and to identify the association between xylem growth and climate. The timing and duration of xylogenesis in histological sections were investigated weekly during the 2013-2015 growing seasons. Our investigation found that timing and duration of xylogenesis varied with canopy position and its associated tree size. Xylogenesis started 6-14 days earlier, and ended 5-11 days later in dominant trees than in suppressed trees, resulting in a significantly longer growing season. Dominant trees also exhibited higher temperature sensitivity of tracheid production rate than suppressed trees. The observed differences in xylogenesis among trees suggested that competition affects tree growth by reducing the growing period in suppressed trees. Representative climate-growth relationships should involve trees of all size classes when evaluating the effects of the environment on forest dynamics. © 2018 Botanical Society of America.

Objectives To identify key health outcomes, beyond morbidity and mortality, regarded as important in children and young people with neurodisability, and their parents. Design Qualitative research incorporating a thematic analysis of the data supported by the Framework Approach; the International Classification of Functioning, Disability and Health (ICF) provided a theoretical foundation. Setting The study was conducted in community settings. Participants Participants were 54 children and young people with neurodisability: 50 participated in focus groups, and 4 in interviews; 53 parents participated: 47 in focus groups and 6 in interviews. Children/young people and parents were recruited through different networks, and were not related. Results Children/young people and parents viewed health outcomes as inter-related. Achievement in some outcomes appeared valued to the extent that it enabled or supported more valued domains of health. Health outcomes prioritised by both young people and parents were: communication, mobility, pain, self-care, temperament, interpersonal relationships and interactions, community and social life, emotional well-being and gaining independence/future aspirations. Parents also highlighted their child's sleep, behaviour and/or safety. Conclusions Those responsible for health services for children/young people with neurodisability should take account of the aspects of health identified by families. The aspects of health identified in this study provide a basis for selecting appropriate health indicators and outcome measures. PMID:24747792

Full Text Available Taibi Kahler wrote in 1974 a theory about five main drivers that could explain people’s motivation and a series of positive and negative behavior patterns: Be Strong, Be Perfect, Hurry Up, Try Hard and Please People. Of course, we consider there is no absolute positive or negative behavior, since (1 everything needs to be analyzed by taking into account the context and (2 any behavior pattern can mean a series of advantages as long as people understand their own values, beliefs, attitudes and behaviors. It would be interesting to link Kahler’s drivers to the educational process, in order to be able to adapt our courses and our teaching styles to students’ requirements and also to the requirements in the labor market. Our paper is built on literature review and a questionnaire applied to a sample of 607 students in Bucharest University of Economic Studies, Romania. Information was processed with Microsoft Excel 2013, in order to look at the main working styles our students have, at the main explanations for the differences between them and in order to test a series of hypotheses. We were interested to look at the main traits of the current generation of students in our university: dominant drivers, roles of managers and specialists, the attractiveness of the entrepreneurial career path, etc. and at a series of patterns (i.e. gender-related differences. We consider results of this study are useful both for teaching and research purposes. In terms of teaching, we plan to adapt our educational methods in order to improve the educational process.

Dominance relationships among siamang males living in multimale groups.
Morino, Luca
2016-03-01
Intense intolerance among males is considered to be an important mechanism maintaining the uni-male organization traditionally attributed to socially monogamous gibbons. Long-term field work, however, has revealed the existence of stable, socially polyandrous groups in at least two populations, raising questions about the mechanism that allows two adult males to co-reside in the same group. I collected 21 months of behavioral data on 7 two-male groups of wild siamangs (Symphalangus syndactylus) in southern Sumatra (Indonesia) to test the hypothesis that dominance relationships regulate the interactions of adult male siamangs and ultimately facilitate multi-male social groups. A dominant male could clearly be identified in each dyad, based on a consistent direction of agonistic interactions, displacements and the maintenance of an advantageous position in the canopy. Males identified as dominant enjoyed greater social access to the resident female and monopolized copulations. These results suggest that gibbons possess the psycho-social flexibility to regulate intra-sexual aggression and live in multi-male social units under certain social conditions. I discuss the effects that relatedness between males and female choice have in determining this grouping pattern, and the role of male intolerance in the maintenance of primate mating systems. © 2015 Wiley Periodicals, Inc.

A subset of older people is at increased risk of hospitalization and dependency. Emerging evidence suggests that immunosenescence reflected by an inverted CD4:8 ratio and cytomegalovirus (CMV) seropositivity plays an important role in the pathophysiology of functional decline. Nevertheless, the relation between CD4:8 ratio and functional outcome has rarely been investigated. Here, CD4:8 ratio and T-cell phenotypes of 235 community-dwelling persons aged ≥81.5 years in the BELFRAIL study and 25 younger persons (mean age 28.5 years) were analyzed using polychromatic flow cytometry. In the elderly persons, 7.2% had an inverted CD4:8 ratio, which was associated with CMV seropositivity, less naive, and more late-differentiated CD4+ and CD8+ T cells. However, 32.8% had a CD4:8 ratio >5, a phenotype associated with a higher proportion of naive T cells and absent in young donors. In CMV seropositives, this subgroup had lower proportions of late-differentiated CD4+ and CD8+ T cells and weaker anti-CMV immunoglobulin G reactivity. This novel naive T-cell-dominated phenotype was counterintuitively associated with a higher proportion of those with impaired physical functioning in the very elderly people infected with CMV. This underscores the notion that in very elderly people, not merely CMV infection but also the state of its accompanying immune dysregulation is of crucial importance with regard to physical impairment. © The Author 2014.

From nature-dominated to human-dominated environmental changes
Messerli, Bruno; Grosjean, Martin; Hofer, Thomas; Núñez, Lautaro; Pfister, Christian
2000-01-01
To what extent is it realistic and useful to view human history as a sequence of changes from highly vulnerable societies of hunters and gatherers through periods with less vulnerable, well buffered and highly productive agrarian-urban societies to a world with regions of extreme overpopulation and overuse of life support systems, so that vulnerability to climatic-environmental changes and extreme events is again increasing? This question cannot be fully answered in our present state of knowledge, but at least we can try to illustrate, with three case studies from different continents, time periods and ecosystems, some fundamental changes in the relationship between natural processes and human activities that occur, as we pass from a nature-dominated to a human dominated environment. 1. Early-mid Holocene: Nature dominated environment — human adaptation, mitigation, and migration. In the central Andes, the Holocene climate changed from humid (10,800-8000 BP) to extreme arid (8000-3600 BP) conditions. Over the same period, prehistoric hunting communities adopted a more sedentary pattern of resource use by settling close to the few perennial water bodies, where they began the process of domesticating camelids around 5000 BP and irrigation from about 3100 BP. 2. Historical period: An agrarian society in transition from an "enduring" to an innovative human response. Detailed documentary evidence from Western Europe may be used to reconstruct quite precisely the impacts of climatic variations on agrarian societies. The period considered spans a major transition from an apparently passive response to the vagaries of the environment during the 16th century to an active and innovative attitude from the onset of the agrarian revolution in the late 18th century through to the present day. The associated changes in technology and in agricultural practices helped to create a society better able to survive the impact of climatic extremes. 3. The present day: A human dominated

In this paper, we discuss the characteristics of microaggressions based on minority language(s) as a form of discriminatory practice against non-dominant students in the mathematics context. Microaggressions are subtle, brief, and commonplace verbal, behavioral, or visual negative slights or insults toward people of color. We extend the concept of microaggression to include discrimination based on a minority language. We draw on our work with Latinas/os in the USA to demonstrate the occurrence of microaggressions in the teaching act. Revealing microaggressions based on language has the potential of creating more equitable learning environments for non-dominant students and can point to possible directions for future research and improvements in the preparation of teachers who serve non-dominant students who speak a language other than the school's official language.

In 2010, two global networks of people living with HIV, the International Community of Women Living with HIV (ICW Global) and the Global Network of People living with HIV (GNP+) were invited to review a draft strategic framework for the global scale up of prevention of vertical transmission (PVT) through the primary prevention of HIV and the prevention of unintended pregnancies among women living with HIV. In order to ensure recommendations were based on expressed needs of people living with HIV, GNP+ and ICW Global undertook a consultation amongst people living with HIV which highlighted both facilitators and barriers to prevention services. This commentary summarizes the results of that consultation. The consultation was comprised of an online consultation (moderated chat-forum with 36 participants from 16 countries), an anonymous online e-survey (601 respondents from 58 countries), and focus-group discussions with people living with HIV in Jamaica (27 participants). The consultation highlighted the discrepancies across regions with respect to access to essential packages of PVT services. However, the consultation participants also identified common barriers to access, including a lack of trustworthy sources of information, service providers' attitudes, and gender-based violence. In addition, participant responses revealed common facilitators of access, including quality counselling on reproductive choices, male involvement, and decentralized services. The consultation provided some understanding and insight into the participants' experiences with and recommendations for PVT strategies. Participants agreed that successful, comprehensive PVT programming require greater efforts to both prevent primary HIV infection among young women and girls and, in particular, targeted efforts to ensure that women living with HIV and their partners are supported to avoid unintended pregnancies and to have safe, healthy pregnancies instead. In addition to providing the insights

The power domination problem is an optimization problem that has emerged together with the development of the power networks. It is important to control the voltage and current in all the nodes and links in a power network. Measuring devices are expensive, which is why there is a tendency to place a minimum number of devices in a power network so that the network remains fully supervised. The k-power domination is a generalization of the power domination. The thesis represents the rules of th...

Functional Anatomy of Writing with the Dominant Hand
Najee-ullah, Muslimah ‘Ali; Hallett, Mark
2013-01-01
While writing performed by any body part is similar in style, indicating a common program, writing with the dominant hand is particularly skilled. We hypothesized that this skill utilizes a special motor network supplementing the motor equivalence areas. Using functional magnetic resonance imaging in 13 normal subjects, we studied nine conditions: writing, zigzagging and tapping, each with the right hand, left hand and right foot. We identified brain regions activated with the right (dominant) hand writing task, exceeding the activation common to right-hand use and the writing program, both identified without right-hand writing itself. Right-hand writing significantly differed from the other tasks. First, we observed stronger activations in the left dorsal prefrontal cortex, left intraparietal sulcus and right cerebellum. Second, the left anterior putamen was required to initiate all the tested tasks, but only showed sustained activation during the right-hand writing condition. Lastly, an exploratory analysis showed clusters in the left ventral premotor cortex and inferior and superior parietal cortices were only significantly active for right-hand writing. The increased activation with right-hand writing cannot be ascribed to increased effort, since this is a well-practiced task much easier to perform than some of the other tasks studied. Because parietal-premotor connections code for particular skills, it would seem that the parietal and premotor regions, together with basal ganglia-sustained activation likely underlie the special skill of handwriting with the dominant hand.

Resting tremor is one of the cardinal motor features of Parkinson's disease (PD). Several lines of evidence suggest resting tremor may have different underlying pathophysiological processes from those of bradykinesia and rigidity. The current study aims to identify white matter microstructural abnormalities associated with resting tremor in PD. We recruited 60 patients with PD (30 with tremor-dominant PD and 30 with nontremor-dominant PD) and 26 normal controls. All participants underwent clinical assessment and diffusion tensor MRI. We used tract-based spatial statistics to investigate white matter integrity across the entire white matter tract skeleton. Compared with both healthy controls and the nontremor-dominant PD patients, the tremor-dominant PD patients were characterized by increased mean diffusivity (MD) and axial diffusivity (AD) along multiple white matter tracts, mainly involving the cerebello-thalamo-cortical (CTC) pathway. The mean AD value in clusters with significant difference was correlated with resting tremor score in the tremor-dominant PD patients. There was no significant difference between the nontremor-dominant PD patients and controls. Our results support the notion that resting tremor in PD is a distinct condition in which significant microstructural white matter changes exist and provide evidence for the involvement of the CTC in tremor genesis of PD.

Language dominance in the right hemisphere is rare. Therefore, the organization of essential language sites in the dominant right hemisphere is unclear, especially compared with cases involving the more prevalent left dominant hemisphere. The authors reviewed the medical records of 15 patients who underwent awake craniotomy for tumor or epilepsy surgery and speech mapping of right hemisphere perisylvian language areas at the University of California, San Francisco. All patients were determined to have either complete right-sided or bilateral language dominance by preoperative Wada testing. All patients but one were left-handed. Of more than 331 total stimulation sites, 27 total sites were identified as essential for language function (14 sites for speech arrest/anarthria; 12 for anomia; and 1 for alexia). While significant interindividual variability was observed, the general pattern of language organization was similar to classic descriptions of frontal language production and posterior temporal language integration for the left hemisphere. Speech arrest sites were clustered in the ventral precentral gyrus and pars opercularis. Anomia sites were more widely distributed, but were focused in the posterior superior and middle temporal gyri as well as the inferior parietal gyrus. One alexia site was found over the superior temporal gyrus. Face sensory and motor cortical sites were also identified along the ventral sensorimotor strip. The prevalence and specificity of essential language sites were greater in unilateral right hemisphere-dominant patients, compared with those with bilateral dominance by Wada testing. The authors' results suggest that the organization of language in right hemisphere dominance mirrors that of left hemisphere dominance. Awake speech mapping is a safe and reliable surgical adjunct in these rare clinical cases and should be done in the setting of right hemisphere dominance to avoid preventable postoperative aphasia.

Authoritarianism, dominance and assertiveness.
Ray, J J
1981-08-01
It is shown that there are definitions of the three constructs of authoritarianism, dominance and assertiveness which read very similarly; so much so that no distinction is immediately evident. It is proposed that authoritarianism might be conceived as aggressive dominance and at least some types of assertiveness as nonaggressive dominance. A new scale of Dominance suitable for general population use was produced, and compared with the existing Ray (1976) behavior inventory of authoritarianism. Both scales showed highly significant correlations with peer rated dominance and submission (the latter being negative in sign) but only the authoritarianism scale showed significant correlations with rated aggressiveness and rigidity. It was concluded that the new definitions could be operationalized into valid scales.

In this review we explore the provision of assistive technology products and services currently available for people with dementia within the United Kingdom. A scoping review of assistive technology products and services currently available highlighted 171 products or product types and 331 services. In addition, we assimilated data on the amount and quality of information provided by assistive technology services alongside assistive technology costs. We identify a range of products available across three areas: assistive technology used 'by', 'with' and 'on' people with dementia. Assistive technology provision is dominated by 'telecare' provided by local authorities, with services being subject to major variations in pricing and information provision; few currently used available resources for assistive technology in dementia. We argue that greater attention should be paid to information provision about assistive technology services across an increasingly mixed economy of dementia care providers, including primary care, local authorities, private companies and local/national assistive technology resources. © The Author(s) 2014.

Identifying people from gait pattern with accelerometers
Ailisto, Heikki J.; Lindholm, Mikko; Mantyjarvi, Jani; Vildjiounaite, Elena; Makela, Satu-Marja
2005-03-01
Protecting portable devices is becoming more important, not only because of the value of the devices themselves, but for the value of the data in them and their capability for transactions, including m-commerce and m-banking. An unobtrusive and natural method for identifying the carrier of portable devices is presented. The method uses acceleration signals produced by sensors embedded in the portable device. When the user carries the device, the acceleration signal is compared with the stored template signal. The method consists of finding individual steps, normalizing and averaging them, aligning them with the template and computing cross-correlation, which is used as a measure of similarity. Equal Error Rate of 6.4% is achieved in tentative experiments with 36 test subjects.

Ageing, sexuality and enhancement among Yoruba people in south western Nigeria.
Agunbiade, Ojo Melvin; Ayotunde, Titilayo
2012-01-01
Sexual health across the life course is influenced by biological and psychosocial factors. The paper explores sexuality and associated practices among older Yoruba people with a view to identifying the implications of cultural beliefs and practices for sexual health in later life. A total of 64 vignette-based in-depth interviews and 12 focus-group discussions were held with older adults (50-75 years) in two Yoruba communities in south western Nigeria. Findings portray sexuality as an important aspect of old age, with sexual intercourse being construed as having physical and spiritual consequences. This same perspective also emerged as participants' attributed factors affecting sexual desire in old age to religious beliefs, poverty, ill health and the non-availability of a partner. Gender differences were dominant on sexual desire and pleasure in old age. Participants' views on causes of sexual dysfunction identified biological, psychosocial and spiritual factors. Sexual decline in old age was considered redeemable with the support of biomedical and traditional medicines. However, only traditional medicine was considered beneficial in addressing sexual dysfunctions that had spiritual dimensions.

Extraction of Protein-Protein Interaction from Scientific Articles by Predicting Dominant Keywords.
Koyabu, Shun; Phan, Thi Thanh Thuy; Ohkawa, Takenao
2015-01-01
For the automatic extraction of protein-protein interaction information from scientific articles, a machine learning approach is useful. The classifier is generated from training data represented using several features to decide whether a protein pair in each sentence has an interaction. Such a specific keyword that is directly related to interaction as "bind" or "interact" plays an important role for training classifiers. We call it a dominant keyword that affects the capability of the classifier. Although it is important to identify the dominant keywords, whether a keyword is dominant depends on the context in which it occurs. Therefore, we propose a method for predicting whether a keyword is dominant for each instance. In this method, a keyword that derives imbalanced classification results is tentatively assumed to be a dominant keyword initially. Then the classifiers are separately trained from the instance with and without the assumed dominant keywords. The validity of the assumed dominant keyword is evaluated based on the classification results of the generated classifiers. The assumption is updated by the evaluation result. Repeating this process increases the prediction accuracy of the dominant keyword. Our experimental results using five corpora show the effectiveness of our proposed method with dominant keyword prediction.

Men's sex-dominance inhibition: do men automatically refrain from sexually dominant behavior?
Kiefer, Amy K; Sanchez, Diana T
2007-12-01
Men receive conflicting messages about their sexual roles in heterosexual relationships. Men are socialized to initiate and direct sexual activities with women; yet societal norms also proscribe the sexual domination and coercion of women. The authors test these competing hypotheses by assessing whether men inhibit the link between sex and dominance. In Studies 1a and b, using a subliminal priming procedure embedded in a lexical decision task, the authors demonstrate that men automatically suppress the concept of dominance following exposure to subliminal sex primes relative to neutral primes. In Studies 2 and 3, the authors show that men who are less likely to perceive sexual assertiveness as necessary, to refrain from dominant sexual behavior, and who do not invest in masculine gender ideals are more likely to inhibit dominant thoughts following sex primes. Implications for theories of automatic cognitive networks and gender-based sexual roles are discussed.

Full Text Available Several studies indicate that dietary habits are associated with mental health. We are interested in identifying not a specific single nutrient/food group but the population preferring specific food combinations that can be related to mental health. Very few studies have examined relationships between dietary patterns and multifaceted mental states using cluster analysis. The purpose of this study was to investigate population-level dietary patterns associated with mental state using cluster analysis. We focused on depressive state, sleep quality, subjective well-being, and impulsive behaviors using rating scales. Two hundred and seventy-nine Japanese middle-aged people participated in the present study. Dietary pattern was estimated using a brief self-administered diet-history questionnaire (the BDHQ. We conducted K-means cluster analysis using thirteen BDHQ food groups: milk, meat, fish, egg, pulses, potatoes, green and yellow vegetables, other vegetables, mushrooms, seaweed, sweets, fruits, and grain. We identified three clusters characterized as "vegetable and fruit dominant," "grain dominant," and "low grain tendency" subgroups. The vegetable and fruit dominant group showed increases in several aspects of subjective well-being demonstrated by the SF-8. Differences in mean subject characteristics across clusters were tested using ANOVA. The low frequency intake of grain group showed higher impulsive behavior, demonstrated by BIS-11 deliberation and sum scores. The present study demonstrated that traditional Japanese dietary patterns, such as eating rice, can help with beneficial changes in mental health.

Whether and how societal structures shape individual psychology is a foundational question of the social sciences. Combining insights from evolutionary biology, economy, and the political and psychological sciences, we identify a central psychological process that functions to sustain group-based hierarchies in human societies. In study 1, we demonstrate that macrolevel structural inequality, impaired population outcomes, socio-political instability, and the risk of violence are reflected in the endorsement of group hegemony at the aggregate population level across 27 countries ( n = 41,824): The greater the national inequality, the greater is the endorsement of between-group hierarchy within the population. Using multilevel analyses in study 2, we demonstrate that these psychological group-dominance motives mediate the effects of macrolevel functioning on individual-level attitudes and behaviors. Specifically, across 30 US states ( n = 4,613), macrolevel inequality and violence were associated with greater individual-level support of group hegemony. Crucially, this individual-level support, rather than cultural-societal norms, was in turn uniquely associated with greater racism, sexism, welfare opposition, and even willingness to enforce group hegemony violently by participating in ethnic persecution of subordinate out-groups. These findings suggest that societal inequality is reflected in people's minds as dominance motives that underpin ideologies and actions that ultimately sustain group-based hierarchy.

Real or symbolic domination: New revision of La Domination masculine
Directory of Open Access Journals (Sweden)
Tassadit Yacine
2017-07-01
Full Text Available This paper does a rereading of Pierre Bourdieu’s Masculine Domination (1998, from the context in which it was developed. Thus, we rely on the work carried out during the 50s in Algeria (Sociologie de l'Algérie, 1958, Esquisse d'une théorie de la pratique, 1972 and Le Sens pratique, 1980 and later in France, to show that Masculine Domination was not born spontaneously, but as a result of a long decantation enriched by field experiences and the theoretical advances of the author’s concepts. If it is true that the situation of the women described in Sociologie de l'Algérie is the result of empirical research, it is less so for Masculine Domination, whose analysis retakes the concepts forged by the social anthropologist, such as habitus and symbolic domination. In this way, this article proposes a rereading of this work through the analysis of the work that preceded it in the field.

Current literature has indicated a concern about standards of maternity care experienced by pregnant women who are seeking asylum. As the next generation of midwives, it is important that students are educated in a way that prepares them to effectively care for these women. To understand how this can be achieved, it is important to explore what asylum seeking means to midwifery students. This article is the first of three parts and reports on one objective from a wider doctorate study. It identifies dominant discourses that influenced the perceptions of a group of midwifery students' about the pregnant asylum seeking woman. The study was designed from a social constructivist perspective, with contextual knowledge being constructed by groups of people, influenced by underpinning dominant discourses, depending on their social, cultural and historical positions in the world. In a United Kingdom University setting, during year two of a pre-registration midwifery programme, eleven midwifery students participated in the study. Two focus group interviews using a problem based learning scenario as a trigger for discussion were conducted. In addition, three students were individually interviewed to explore issues in more depth and two students' written reflections on practice were used to generate data. Following a critical discourse analysis, dominant discourses were identified which appeared to influence the way in which asylum seekers were perceived. The findings suggested an underpinning ideology around the asylum seeker being different and of a criminal persuasion. Although the pregnant woman seeking asylum was considered as deserving of care, the same discourses appeared to influence the way in which she was constructed. However, as the study progressed, through reading alternative sources of literature, some students appeared to question these discourses. These findings have implications for midwifery education in encouraging students to challenge negative discourses

Molecular Diagnostics in Autosomal Dominant Polycystic Kidney Disease: Utility and Limitations
Zhao, Xiao; Paterson, Andrew D.; Zahirieh, Alireza; He, Ning; Wang, Kairong; Pei, York
2008-01-01
Background and objectives: Gene-based mutation screening is now available and has the potential to provide diagnostic confirmation or exclusion of autosomal dominant polycystic kidney disease. This study illustrates its utility and limitations in the clinical setting. Design, setting, participants, & measurements: Using a molecular diagnostic service, genomic DNA of one affected individual from each study family was screened for pathologic PKD1 and PKD2 mutations. Bidirectional sequencing was performed to identify sequence variants in all exons and splice junctions of both genes and to confirm the specific mutations in other family members. In two multiplex families, microsatellite markers were genotyped at both PDK1 and PKD2 loci, and pair-wise and multipoint linkage analysis was performed. Results: Three of five probands studied were referred for assessment of renal cystic disease without a family history of autosomal dominant polycystic kidney disease, and two others were younger at-risk members of families with autosomal dominant polycystic kidney disease being evaluated as living-related kidney donors. Gene-based mutation screening identified pathogenic mutations that provided confirmation or exclusion of disease in three probands, but in the other two, only unclassified variants were identified. In one proband in which mutation screening was indeterminate, DNA linkage studies provided strong evidence for disease exclusion. Conclusions: Gene-based mutation screening or DNA linkage analysis should be considered in individuals in whom the diagnosis of autosomal dominant polycystic kidney disease is uncertain because of a lack of family history or equivocal imaging results and in younger at-risk individuals who are being evaluated as living-related kidney donors.

Discourses of Linguistic dominance: A Historical Consideration of French Language Ideology
Kasuya, Keisuke
2001-07-01
The paper offers a historical perspective on the linguistic and cultural imperialism embedded in the struggle to maintain French as a leading international language. France was the nation-state where the ideology of national language was first clearly formulated and directly extended to overseas colonies. This shows the close relationship between linguistic nationalism and imperialism. It was believed that French was the language of universal human reason and had the power to civilize people who spoke it. This myth of the "clarté française" and the "mission civilisatrice" had a strong influence on various kinds of metalinguistic discourses that created the taken-for-granted representation of French as dominant language. It is the essential strategy of language dominance to establish the hierarchy of languages as if it were natural order of things. When French was obliged to yield the status of international language to English, there emerged the ideology of "Francophonie" which tried to defend its privilege against the monopoly of English, but the same ideology is also directed against minorities' claims for their own linguistic human right. It could be said that these discourses form a recursive prototype of language dominance whose variations are to be found in other shapes almost all over the world.

Full Text Available BACKGROUND AND OBJECTIVE: From the viewpoint of Traditional Persian Medicine (TPM, temperament of each person influences his physical and physiological properties such as body dimensions. The aim of this study is to review the reasons behind the diversity of human anthropometric measurements and their status in identifying temperament of people. METHODS: In this descriptive study, we searched online databases such as Sid.ir, PubMed, Scopus, Magiran.com and Google Scholar for Persian key words such as "Anthropometry", "ergonomics" and "temperament" and their English equivalent. Authentic TPM books such as "The Canon of Medicine" by Avicenna, "Complete Book of the Medical Art" by al-Majusi, "al-Mansouri fi al-Tibb" (The book on medicine dedicated to al-Mansur by Zakariya al-Razi, " Kholasa't ol Hikma" (summary of wisdom by Aghili Khorasani, “Zakhireh kharazmshahi”(The treasure of Kharazm Shah by Ismail Jurjani and "Bahr al-jawahir" (sea jewels were also studied. FINDINGS: Results of the study demonstrated that there is a direct relationship between weight gain, BMI and dimensions of soft tissue which are primarily signs of obesity and fat gain and cardiovascular diseases and diabetes. Since increase in the aforementioned indices can be a sign of coldness and wetness of temperament, one can argue that people with cold and wet temperament are more susceptible to such diseases. In references of TPM, temperament is mentioned as an agent that changes body dimensions and among the indices that identify temperament, "shape of organs" and "physique" is related to anatomic dimensions of body and obesity and thinness condition, receptively. Magnitude of chest and other organs is a sign of hotness; thinness is a sign of dryness; dominance of muscle tissue is a sign of hotness and wetness and dominance of adipose tissue is a sign of coldness and wetness of temperament. CONCLUSION: According to the results of the present study, variety of anthropometric

The Pricing Strategies and the Dominant Technology Modes
Directory of Open Access Journals (Sweden)
Kramarenko Anna О.
2017-11-01
Full Text Available The article is aimed at defining the basic approaches to pricing that correspond to the modern technological mode, as well as the prospects of substituting them with new strategies in the process of evolution of technology and socio-economic development. The technological evolution within the terms of cyclic substitution of the dominant technological ways together with periodicity of domination of the single pricing strategies have been considered. It was identified that in the process of transition to the sixth technological mode, the core of which is the high-tech and the science-driven types of economic activity, the strategies of premium pricing are at the forefront, due to their significant profitability in conditions of the fast updating of assortment of products and the particular characteristics of products and services. It has been substantiated that the dominance of premium pricing creates an inflationary effect, especially in the terms of innovative economic activities, which are potentially the basis for active implementation of technologies of the new mode.

Perfect secure domination in graphs
Directory of Open Access Journals (Sweden)
S.V. Divya Rashmi
2017-07-01
Full Text Available Let $G=(V,E$ be a graph. A subset $S$ of $V$ is a dominating set of $G$ if every vertex in $Vsetminus S$ is adjacent to a vertex in $S.$ A dominating set $S$ is called a secure dominating set if for each $vin Vsetminus S$ there exists $uin S$ such that $v$ is adjacent to $u$ and $S_1=(Ssetminus{u}cup {v}$ is a dominating set. If further the vertex $uin S$ is unique, then $S$ is called a perfect secure dominating set. The minimum cardinality of a perfect secure dominating set of $G$ is called the perfect secure domination number of $G$ and is denoted by $gamma_{ps}(G.$ In this paper we initiate a study of this parameter and present several basic results.

We used a Support Vector Machine (SVM) classifier to assess hemispheric pattern of language dominance of 47 individuals categorized as non-typical for language from their hemispheric functional laterality index (HFLI) measured on a sentence minus word-list production fMRI-BOLD contrast map. The SVM classifier was trained at discriminating between Dominant and Non-Dominant hemispheric language production activation pattern on a group of 250 participants previously identified as Typicals (HFLI strongly leftward). Then, SVM was applied to each hemispheric language activation pattern of 47 non-typical individuals. The results showed that at least one hemisphere (left or right) was found to be Dominant in every, except 3 individuals, indicating that the "dominant" type of functional organization is the most frequent in non-typicals. Specifically, left hemisphere dominance was predicted in all non-typical right-handers (RH) and in 57.4% of non-typical left-handers (LH). When both hemisphere classifications were jointly considered, four types of brain patterns were observed. The most often predicted pattern (51%) was left-dominant (Dominant left-hemisphere and Non-Dominant right-hemisphere), followed by right-dominant (23%, Dominant right-hemisphere and Non-Dominant left-hemisphere) and co-dominant (19%, 2 Dominant hemispheres) patterns. Co-non-dominant was rare (6%, 2 Non-Dominant hemispheres), but was normal variants of hemispheric specialization. In RH, only left-dominant (72%) and co-dominant patterns were detected, while for LH, all types were found, although with different occurrences. Among the 10 LH with a strong rightward HFLI, 8 had a right-dominant brain pattern. Whole-brain analysis of the right-dominant pattern group confirmed that it exhibited a functional organization strictly mirroring that of left-dominant pattern group.

Elucidating dominant pathways of the nano-particle self-assembly process.
Zeng, Xiangze; Li, Bin; Qiao, Qin; Zhu, Lizhe; Lu, Zhong-Yuan; Huang, Xuhui
2016-09-14
Self-assembly processes play a key role in the fabrication of functional nano-structures with widespread application in drug delivery and micro-reactors. In addition to the thermodynamics, the kinetics of the self-assembled nano-structures also play an important role in determining the formed structures. However, as the self-assembly process is often highly heterogeneous, systematic elucidation of the dominant kinetic pathways of self-assembly is challenging. Here, based on mass flow, we developed a new method for the construction of kinetic network models and applied it to identify the dominant kinetic pathways for the self-assembly of star-like block copolymers. We found that the dominant pathways are controlled by two competing kinetic parameters: the encounter time Te, characterizing the frequency of collision and the transition time Tt for the aggregate morphology change from rod to sphere. Interestingly, two distinct self-assembly mechanisms, diffusion of an individual copolymer into the aggregate core and membrane closure, both appear at different stages (with different values of Tt) of a single self-assembly process. In particular, the diffusion mechanism dominates the middle-sized semi-vesicle formation stage (with large Tt), while the membrane closure mechanism dominates the large-sized vesicle formation stage (with small Tt). Through the rational design of the hydrophibicity of the copolymer, we successfully tuned the transition time Tt and altered the dominant self-assembly pathways.

Based on the previous studies, we know that the hemispheric lateralization defects, increase the probability of psychological disorders. We also know that dominant limb is controlled by dominant hemisphere and limb preference is used as an indicator for hemisphere dominance. In this study we attempted to explore the hemispheric dominance by the use of three limbs (hand, foot and eye). We performed this survey on two samples, psychiatric patients compared with normal population. For this purpose, knowing that the organ dominance is stabilized in adolescence, and age has no effect on the people above 15, we used 48 high school girls and 65 boys as the final samples of normal population. The patient group included 57 male and 26 female who were chronic psychiatric patients. The result shows that left-eye dominance is more in patients than the normal group (P=0.000) but the handedness and footedness differences are not significance. In psychotic, bipolar and depressive disorders, eye dominance had significant difference (P=0.018). But this is not true about hand and foot dominance. Our findings proved that generally in psychiatric patients, left-eye dominance is more common, left-eye dominance is also more in psychotic and depressive disorders. It is less common in bipolar disorders.

Guided by Beck's (1967) cognitive theory of depression, we assessed whether perceived family functioning (PFF) mediated the relationship between depressive symptomatology and help-seeking inclinations. Study 1 included 130 Spanish-Dominant Hispanics and Study 2 included 124 Non-Hispanic Whites obtained using online crowd sourcing. Participants completed measures of depressive symptomatology, PFF, and several scales measuring aspects of help seeking inclinations and self-stigma. Study 2 also included an experiment. With an eye toward potential future interventions, we assessed the malleability of PFF. Specifically, participants were randomly assigned to recall positive or negative family experiences and then PFF was measures for a second time. Both studies found PFF mediates the relationship between depressive symptomatology and the help seeking scales. Among non-depressed people, the positive manipulation improved PFF; however, among participants with elevated depressive symptomatology, writing about a positive family experience worsened PFF. With the exception of the experiment, most of the data were cross-sectional. For the experiment, it is possible that different manipulations or primes could have different effects. Whether investigating responses from Spanish-Dominant Hispanics or Non-Hispanic Whites, PFF mediates the negative relationship between heightened depressive symptomatology and familial help-seeking beliefs, as well as self-stigma. However, even though the mediation analysis offers preliminary support that increasing PFF can potentially increase help-seeking behaviors of Hispanic and Non-Hispanic White people with depression, the results of the interaction analysis, specifically the negative impact of writing about positive family memories on people with elevated depression, illustrates the challenges of persuading people with depression.

The socialization of dominance: peer group contextual effects on homophobic and dominance attitudes.
Poteat, V Paul; Espelage, Dorothy L; Green, Harold D
2007-06-01
Using the framework of social dominance theory, the current investigation tested for the contextual effects of adolescent peer groups on individuals' homophobic and social dominance attitudes. Results from multilevel models indicated that significant differences existed across peer groups on homophobic attitudes. In addition, these differences were accounted for on the basis of the hierarchy-enhancing or -attenuating climate of the group. A group socialization effect on individuals' social dominance attitudes over time was also observed. Furthermore, the social climate of the peer group moderated the stability of individuals' social dominance attitudes. Findings support the need to examine more proximal and informal group affiliations and earlier developmental periods in efforts to build more comprehensive theoretical models explaining when and how prejudiced and dominance attitudes are formed and the way in which they are perpetuated.

The Theory of Planned Behavior was used to identify the key behavioural, normative and control beliefs underlying intentions to test regularly for chlamydia among young people living in socially and economically deprived areas - a high-risk group for infection. Participants (N = 278, 53% male; mean age 17 years) were recruited from a vocational college situated in an area in the most deprived national quintile (England). Participants completed measures of behavioural, normative and control beliefs, plus intention to test regularly for chlamydia. The behavioural, normative and control beliefs most strongly correlated with intentions to test regularly for chlamydia were beliefs about stopping the spread of infection, partners' behaviour and the availability of testing. These beliefs represent potential targets for interventions to increase chlamydia testing among young people living in deprived areas. © The Author(s) 2013.

The Long-Term Effects of Racial Microaggressions on People of Color in STEM
Smith, William
2017-10-01
People of Color experience acute or chronic stress from discriminatory treatment and racial microaggressions, decreasing their biopsychosocial health. Racial microaggressions include but are not limited to merciless and mundane exclusionary messages, being treated as less than fully human, and civil and human rights violations. Racial microaggressions are key to understanding increases in Racial Battle Fatigue (Smith, 2004) resulting from the psychological and physiological stress that racially marginalized individuals/groups experience in response to specific race-related interactions between them and the surrounding dominant environment. Race-related stress taxes and exceeds available resilient coping resources for People of Color, while many Whites easily build sociocultural and economic environments and resources that shield them from race-based stress and threats to their racial entitlements.What is at stake, here, is the quest for equilibrium versus disequilibrium in a society that marginalizes human beings into substandard racial groups. Identifying and counteracting the biopsychosocial and behavioral consequences of actual or perceived racism, gendered-racism, and Racial Battle Fatigue is a premier challenge of the 21st Century. The term "racial microaggressions" was introduced in the 1970's to help psychiatrists and psychologists understand the enormity and complications of the subtle but constant racial blows faced by People of Color. Today, racial microaggressions continue to contribute to the negative workplace experiences of women, people of color, and other marginalized groups in astronomy and planetary science (Clancy et al. 2017). This presentation will focus on the definition, identification, and long-term effects of racial microaggressions and the resultant racial battle fatigue in STEM work environments.

The size of clusters in a neutrino-dominated universe

White, S.D.M.; Davis, M.; Frenk, C.S.

Quite soon after the first collapse of structure almost half the matter in a neutrino-dominated universe is expected to reside in clusters. The masses and binding energies of these neutrino clusters are too large for them to be identified with observed galaxy clusters. Even if such objects were able to suppress all galaxy formation, their X-ray emission would, however, make them highly visible if more than 2.5 per cent of their mass was in ordinary matter. Such a low baryon density leads to insufficient cooling for galaxies to form in pancakes. A neutrino-dominated universe appears to conflict with observation irrespective of the details of the processes which govern galaxy formation. (author)

Full Text Available This paper reports on a Critical Discourse Analysis study situated within a postcolonial theoretical framework and informed by Foucauldian analysis and the lens of governmentality. The study examined official Canadian immigration documents and guidelines. Findings suggest that discourses of risk and protection are used to mask dominant health discourses that construct immigration applicants with disabilities as the "inadmissible Other". Implications for social work and other helping professions involved in facilitating immigration and settlement for newcomers with disabilities are discussed, and suggestions for future directions in research are offered.

Elitism and Stochastic Dominance
Bazen, Stephen; Moyes, Patrick
2011-01-01
Stochastic dominance has typically been used with a special emphasis on risk and inequality reduction something captured by the concavity of the utility function in the expected utility model. We claim that the applicability of the stochastic dominance approach goes far beyond risk and inequality measurement provided suitable adpations be made. We apply in the paper the stochastic dominance approach to the measurment of elitism which may be considered the opposite of egalitarianism. While the...

Daily streamflow information is critical for solving various hydrologic problems, though observations of continuous streamflow for model calibration are available at only a small fraction of the world’s rivers. One approach to estimate daily streamflow at an ungauged location is to transfer rainfall–runoff model parameters calibrated at a gauged (donor) catchment to an ungauged (receiver) catchment of interest. Central to this approach is the selection of a hydrologically similar donor. No single metric or set of metrics of hydrologic similarity have been demonstrated to consistently select a suitable donor catchment. We design an experiment to diagnose the dominant controls on successful hydrologic model parameter transfer. We calibrate a lumped rainfall–runoff model to 83 stream gauges across the United States. All locations are USGS reference gauges with minimal human influence. Parameter sets from the calibrated models are then transferred to each of the other catchments and the performance of the transferred parameters is assessed. This transfer experiment is carried out both at the scale of the entire US and then for six geographic regions. We use classification and regression tree (CART) analysis to determine the relationship between catchment similarity and performance of transferred parameters. Similarity is defined using physical/climatic catchment characteristics, as well as streamflow response characteristics (signatures such as baseflow index and runoff ratio). Across the entire US, successful parameter transfer is governed by similarity in elevation and climate, and high similarity in streamflow signatures. Controls vary for different geographic regions though. Geology followed by drainage, topography and climate constitute the dominant similarity metrics in forested eastern mountains and plateaus, whereas agricultural land use relates most strongly with successful parameter transfer in the humid plains.

Urban Bird Feeders Dominated by a Few Species and Individuals
Directory of Open Access Journals (Sweden)
Josie A. Galbraith
2017-08-01
Full Text Available The practice of garden bird feeding is a global phenomenon, involving millions of people and vast quantities of food annually. Many people engage in the practice of feeding assuming that birds gain some benefit from the food they provide, yet recent studies have revealed the potential for detrimental impacts as well. However, there is still a paucity of information on the impacts of feeding, including the ubiquity of these impacts among and within feeder-visiting species. Consistency in feeder use among birds is likely an important determinant of this. Individual birds and species that make frequent use of feeders are more likely to experience both the benefits and detrimental impacts of supplementary food. We investigated patterns of feeder use by garden birds visiting experimental feeding stations in Auckland, New Zealand, with the specific aim of determining whether use of supplementary food was consistent or variable among individuals and species. We used camera traps as well as Radio Frequency Identification (RFID technology to examine intra- and interspecific feeder visitation patterns and to discern species associations. Eleven bird species were detected using feeding stations, however, two introduced species (house sparrow Passer domesticus and spotted dove Streptopelia chinensis dominated visitation events. These species were present at feeders most frequently, with the largest conspecific group sizes. Significant associations were detected among a number of species, suggesting interspecific interactions are important in determining feeder use. We also found within-species differences in feeder use for all focal species, with individual variation greatest in house sparrows. Furthermore, season had an important influence on most visitation parameters. The observed individual and species-specific differences in supplementary food resource use imply that the impacts of garden bird feeding are not universal. Crucially, particularly given

Perceiving groups: The people perception of diversity and hierarchy.
Phillips, L Taylor; Slepian, Michael L; Hughes, Brent L
2018-05-01
The visual perception of individuals has received considerable attention (visual person perception), but little social psychological work has examined the processes underlying the visual perception of groups of people (visual people perception). Ensemble-coding is a visual mechanism that automatically extracts summary statistics (e.g., average size) of lower-level sets of stimuli (e.g., geometric figures), and also extends to the visual perception of groups of faces. Here, we consider whether ensemble-coding supports people perception, allowing individuals to form rapid, accurate impressions about groups of people. Across nine studies, we demonstrate that people visually extract high-level properties (e.g., diversity, hierarchy) that are unique to social groups, as opposed to individual persons. Observers rapidly and accurately perceived group diversity and hierarchy, or variance across race, gender, and dominance (Studies 1-3). Further, results persist when observers are given very short display times, backward pattern masks, color- and contrast-controlled stimuli, and absolute versus relative response options (Studies 4a-7b), suggesting robust effects supported specifically by ensemble-coding mechanisms. Together, we show that humans can rapidly and accurately perceive not only individual persons, but also emergent social information unique to groups of people. These people perception findings demonstrate the importance of visual processes for enabling people to perceive social groups and behave effectively in group-based social interactions.

Lynch syndrome (hereditary nonpolypsis colorectal cancer or HNPCC) is a common cancer predisposition syndrome. Predisposition to cancer in this syndrome results from increased accumulation of mutations due to defective mismatch repair (MMR) caused by a mutation in one of the mismatch repair genes MLH1, MSH2, MSH6 or PMS2/scPMS1. To better understand the function of Mlh1-Pms1 in MMR, we used Saccharomyces cerevisiae to identify six pms1 mutations (pms1-G683E, pms1-C817R, pms1-C848S, pms1-H850R, pms1-H703A and pms1-E707A) that were weakly dominant in wild-type cells, which surprisingly caused a strong MMR defect when present on low copy plasmids in an exo1Δ mutant. Molecular modeling showed these mutations caused amino acid substitutions in the metal coordination pocket of the Pms1 endonuclease active site and biochemical studies showed that they inactivated the endonuclease activity. This model of Mlh1-Pms1 suggested that the Mlh1-FERC motif contributes to the endonuclease active site. Consistent with this, the mlh1-E767stp mutation caused both MMR and endonuclease defects similar to those caused by the dominant pms1 mutations whereas mutations affecting the predicted metal coordinating residue Mlh1-C769 had no effect. These studies establish that the Mlh1-Pms1 endonuclease is required for MMR in a previously uncharacterized Exo1-independent MMR pathway.

Access to adequate housing consistent with personal preferences and needs is a human right and supports recovery from psychosis. This study aimed to: (1) describe people with psychosis living in different housing types, and their preferences and needs; (2) explore selected demographic and social inclusion correlates in relation to housing; and (3) compare two subgroups - participants living in supported group accommodation and supported housing - on key demographic, functional, clinical and social inclusion variables. Current housing, preferences, needs and assistance, and housing-related social inclusion variables were assessed in a two-phase prevalence survey conducted within seven catchment areas across five Australian states. Two supported housing models were compared: supported group accommodation and supported housing (rental accommodation with in-reach support). Descriptive statistics were used. Of the total participants (n = 1825), one half were living in public or private rented housing (48.6%) and 22.7% were waiting for public housing. Despite being the preferred form of housing, only 13.1% were living in their own home. One in 20 participants (5.2%) was currently homeless; 12.8% had been homeless in the previous 12 months. Residents of supported group accommodation felt safer in their locality than those in supported housing, but experienced less privacy and choice. Although fewer participants were homeless compared with the first Australian survey of psychosis, the proportion remains high. Housing difficulties are experienced by people with psychoses living in various accommodation and concern housing adequacy and safety as well as autonomy and choice. Access to public housing is restricted compared with the identified need. Since residents of supported group accommodation felt safer in their locality than those in supported housing, but experienced less privacy and choice, each supported housing model may offer different advantages to people with

Full Text Available A path π = (v1, v2, . . . , vk+1 in a graph G = (V,E is a downhill path if for every i, 1 ≤ i ≤ k, deg(vi ≥ deg(vi+1, where deg(vi denotes the degree of vertex vi ∈ V. The downhill domination number equals the minimum cardinality of a set S ⊆ V having the property that every vertex v ∈ V lies on a downhill path originating from some vertex in S. We investigate downhill domination numbers of graphs and give upper bounds. In particular, we show that the downhill domination number of a graph is at most half its order, and that the downhill domination number of a tree is at most one third its order. We characterize the graphs obtaining each of these bounds

Like most social animals, crayfish readily form dominance relationships and linear social hierarchies when competing for limited resources. Competition often entails dyadic aggressive interactions, from which one animal emerges as the dominant and one as the subordinate. Once dominance relationships are formed, they typically remain stable for extended periods of time; thus, access to future resources is divided unequally among conspecifics. We previously showed that firmly established dominance relationships in juvenile crayfish can be disrupted by briefly adding a larger conspecific to the original pair. This finding suggested that the stability of social relationships in crayfish was highly context-dependent and more transient than previously assumed. We now report results that further identify the mechanisms underlying the destabilization of crayfish dominance relationships. We found that rank orders remained stable when conspecifics of smaller or equal size were added to the original pair, suggesting that both dominant and subordinate must be defeated by a larger crayfish in order to destabilize dominance relationships. We also found that dominance relationships remained stable when both members of the original pair were defeated by larger conspecifics in the absence of their original opponent. This showed that dominance relationships are not destabilized unless both animals experience defeat together. Lastly, we found that dominance relationships of pairs were successfully disrupted by larger intruders, although with reduced magnitude, after all chemical cues associated with earlier agonistic experiences were eliminated. These findings provide important new insights into the contextual features that regulate the stability of social dominance relationships in crayfish and probably in other species as well. © 2016 Marine Biological Laboratory.

Nemaline myopathy (NEM) is one of the three major forms of congenital myopathy and is characterized by diffuse muscle weakness, hypotonia, respiratory insufficiency, and the presence of nemaline rod structures on muscle biopsy. Mutations in troponin T1 (TNNT1) is 1 of 10 genes known to cause NEM. To date, only homozygous nonsense mutations or compound heterozygous truncating or internal deletion mutations in TNNT1 gene have been identified in NEM. This extended family is of historical importance as some members were reported in the 1960s as initial evidence that NEM is a hereditary disorder. Proband and extended family underwent Sanger sequencing for TNNT1. We performed RT-PCR and immunoblot on muscle to assess TNNT1 RNA expression and protein levels in proband and father. We report a novel heterozygous missense mutation of TNNT1 c.311A>T (p.E104V) that segregated in an autosomal dominant fashion in a large family residing in the United States. Extensive sequencing of the other known genes for NEM failed to identify any other mutant alleles. Muscle biopsies revealed a characteristic pattern of nemaline rods and severe myofiber hypotrophy that was almost entirely restricted to the type 1 fiber population. This novel mutation alters a residue that is highly conserved among vertebrates. This report highlights not only a family with autosomal dominant inheritance of NEM, but that this novel mutation likely acts via a dominant negative mechanism. © 2017 The Authors.

Resting tremor is one of the cardinal motor features of Parkinson's disease (PD). Several lines of evidence suggest resting tremor may have different underlying pathophysiological processes from those of bradykinesia and rigidity. The current study aims to identify white matter microstructural abnormalities associated with resting tremor in PD. We recruited 60 patients with PD (30 with tremor-dominant PD and 30 with nontremor-dominant PD) and 26 normal controls. All participants underwent clinical assessment and diffusion tensor MRI. We used tract-based spatial statistics to investigate white matter integrity across the entire white matter tract skeleton. Compared with both healthy controls and the nontremor-dominant PD patients, the tremor-dominant PD patients were characterized by increased mean diffusivity (MD) and axial diffusivity (AD) along multiple white matter tracts, mainly involving the cerebello-thalamo-cortical (CTC) pathway. The mean AD value in clusters with significant difference was correlated with resting tremor score in the tremor-dominant PD patients. There was no significant difference between the nontremor-dominant PD patients and controls. Our results support the notion that resting tremor in PD is a distinct condition in which significant microstructural white matter changes exist and provide evidence for the involvement of the CTC in tremor genesis of PD.

Full Text Available A Roman dominating function (or just RDF on a graph G = (V,E is a function f : V → {0, 1, 2} satisfying the condition that every vertex u for which f(u = 0 is adjacent to at least one vertex v for which f(v = 2. The weight of an RDF f is the value f(V (G = Pu2V (G f(u. The Roman domination number of a graph G, denoted by R(G, is the minimum weight of a Roman dominating function on G. A graph G is Roman domination stable if the Roman domination number of G remains unchanged under removal of any vertex. In this paper we present upper bounds for the Roman domination number in the class of Roman domination stable graphs, improving bounds posed in [V. Samodivkin, Roman domination in graphs: the class RUV R, Discrete Math. Algorithms Appl. 8 (2016 1650049].

On the dominant noise components of tactical aircraft: Laboratory to full scale
Tam, Christopher K. W.; Aubert, Allan C.; Spyropoulos, John T.; Powers, Russell W.
2018-05-01
This paper investigates the dominant noise components of a full-scale high performance tactical aircraft. The present study uses acoustic measurements of the exhaust jet from a single General Electric F414-400 turbofan engine installed in a Boeing F/A-18E Super Hornet aircraft operating from flight idle to maximum afterburner. The full-scale measurements are to the ANSI S12.75-2012 standard employing about 200 microphones. By comparing measured noise spectra with those from hot supersonic jets observed in the laboratory, the dominant noise components specific to the F/A-18E aircraft at different operating power levels are identified. At intermediate power, it is found that the dominant noise components of an F/A-18E aircraft are essentially the same as those of high temperature supersonic laboratory jets. However, at military and afterburner powers, there are new dominant noise components. Their characteristics are then documented and analyzed. This is followed by an investigation of their origin and noise generation mechanisms.

People into Employment: supporting people with disabilities and carers into work.
Arksey, Hilary
2003-05-01
Carers and people with disabilities are two disadvantaged groups at risk of social exclusion. Work is an important route to social inclusion, but carers and people with disabilities are under-represented in the work force. The present paper reports key findings from a new study that evaluated People into Employment (PIE), a pilot employment project in the north-east of England designed to support people with disabilities, carers and former carers in gaining mainstream work. The study aimed to identify what clients, partner agencies and employers perceived to be PIE's most important services, its strengths and areas where there was scope for further development. The study collected quantitative and qualitative data at the mid-point and at the end of the project through two questionnaire surveys, and interviews with PIE clients, the project development officer, partner agencies and employers. Drawing on the 'pathway model', the findings show that PIE's interventions included mobilising, matching, mediating and supporting activities. Key ingredients in PIE's success include: tailor-made job-search activities and training; adjusting the pace at which people move towards sustained employment; recognising and responding to the differing needs of people with disabilities, carers and former carers; confidence boosting; accompanying clients to job interviews; good job matching; and ongoing practical and emotional support for both clients and employers. Rudimentary calculations suggest that the cost per job to the project is less than the cost per job for large national projects. Overall, these findings illustrate how access to employment via flexible job-search services geared up to the local labour market can successfully promote social inclusion for carers and people with disabilities.

Genetic Dominance & Cellular Processes
Seager, Robert D.
2014-01-01
In learning genetics, many students misunderstand and misinterpret what "dominance" means. Understanding is easier if students realize that dominance is not a mechanism, but rather a consequence of underlying cellular processes. For example, metabolic pathways are often little affected by changes in enzyme concentration. This means that…

Drug Policy and Indigenous Peoples.
Burger, Julian; Kapron, Mary
2017-06-01
This paper identifies the principal concerns of indigenous peoples with regard to current international treaties on certain psychoactive substances and policies to control and eradicate their production, trafficking, and sale. Indigenous peoples have a specific interest in the issue since their traditional lands have become integrated over time into the large-scale production of coca, opium poppy, and cannabis crops, in response to high demand from the American and European markets, among others. As a consequence, indigenous peoples are persecuted because of their traditional use of these and other plant-based narcotics and hallucinogens. They are also victims of the drug producers who remove them from their lands or forcibly recruit them into the production process. As indigenous peoples are caught in the violent world of illicit drug production, law enforcement often targets them first, resulting in disproportionate rates of criminalization and incarceration.

Differential expression of social dominance as a function of age and maltreatment experience.
Teisl, Michael; Rogosch, Fred A; Oshri, Assaf; Cicchetti, Dante
2012-03-01
Recent perspectives on social dominance in normative populations have suggested a developmental progression from using primarily coercive strategies to incorporation of more socially competent strategies to attain material and social resources. Parental influences on the resource control strategies children use have been proposed but not investigated empirically. The present study examined age- and gender-related differences in dominance strategies in 470 children from high-risk neighborhoods who were between 6 and 13 years of age, approximately half of whom had experienced maltreatment. A Q-sort measure of social dominance was developed and received preliminary support. Consistent with predictions from resource control theory, age-related differences in dominance-related behavior were demonstrated in both nonmaltreated and maltreated children. Maltreated children were more likely than nonmaltreated children to be identified as dominant bullies at any age. Dominance and bullying were not more likely to be associated for children who had experienced physical and sexual abuse relative to those who were neglected or emotionally maltreated. Results are discussed in terms of the influence of maltreatment on the social development of children, and intervention approaches for limiting these deleterious effects are recommended.

Mapping the evidence for the prevention and treatment of eating disorders in young people
2014-01-01
Abstract Eating disorders often develop during adolescence and young adulthood, and are associated with significant psychological and physical burden. Identifying evidence-based interventions is critical and there is need to take stock of the extant literature, to inform clinical practice regarding well-researched interventions and to direct future research agendas by identifying gaps in the evidence base. Aim To investigate and quantify the nature and distribution of existing high-quality research on the prevention and treatment of eating disorders in young people using evidence mapping methodology. Method A systematic search for prevention and treatment intervention studies in adolescents and young adults (12–25 years) was conducted using EMBASE, PSYCINFO and MEDLINE. Studies were screened and mapped according to disorder, intervention modality, stage of eating disorder and study design. Included studies were restricted to controlled trials and systematic reviews published since 1980. Results The eating disorders evidence map included 197 trials and 22 systematic reviews. Prevention research was dominated by trials of psychoeducation (PE). Bulimia nervosa (BN) received the most attention in the treatment literature, with cognitive behavioural therapy (CBT) and antidepressants the most common interventions. For anorexia nervosa (AN), family based therapy (FBT) was the most studied. Lacking were trials exploring treatments for binge eating disorder (BED) and eating disorder not otherwise specified (EDNOS). Relapse prevention strategies were notably absent across the eating disorders. Conclusions Despite substantial literature devoted to the prevention and treatment of eating disorders in young people, the evidence base is not well established and significant gaps remain. For those identified as being at-risk, there is need for prevention research exploring strategies other than passive PE. Treatment interventions targeting BED and EDNOS are required, as are

Full Text Available The purpose of this study was to compare unilateral squat strength of the dominant and non-dominant leg in young adult men and women. Seventeen apparently healthy men (mean mass 90.5 ± 20.9 kg and age 21.7 ± 1.8 yrs and 25 women (mean mass 62.2 ± 14.5 kg and age 21.9 ± 1.3 yrs completed the study. To determine unilateral strength, the subjects completed a one repetition maximum (1RM modified unilateral squat (MUS on the dominant and non-dominant leg. The subjects completed the squat to a depth that attained a 90º angle at the knee. This exercise was executed by placing the top of the metatarsophalangeal area of the foot of the uninvolved leg on a support bar behind the subject to isolate the use of the lead leg. Paired samples t-test revealed no significant difference between the men's 1RM mean strength on the dominant (107.0 ± 21.4 kg and non-dominant (106.0 ± 21.4 kg leg with a mean side-to-side difference (comparing the stronger to the weaker leg of 2.8 %. Leg strength symmetry was also found between the women's 1RM mean strength on the dominant (45.3 ± 12.5 kg and non-dominant (45.0 ± 12.4 kg leg with a mean side-to-side difference of 5.0 %. The data indicate that unilateral squat strength, measured in a weight bearing stance, is similar in the dominant and non-dominant leg in apparently healthy young adult men and women

Neural mechanisms of social dominance
Watanabe, Noriya; Yamamoto, Miyuki
2015-01-01
In a group setting, individuals' perceptions of their own level of dominance or of the dominance level of others, and the ability to adequately control their behavior based on these perceptions are crucial for living within a social environment. Recent advances in neural imaging and molecular technology have enabled researchers to investigate the neural substrates that support the perception of social dominance and the formation of a social hierarchy in humans. At the systems' level, recent studies showed that dominance perception is represented in broad brain regions which include the amygdala, hippocampus, striatum, and various cortical networks such as the prefrontal, and parietal cortices. Additionally, neurotransmitter systems such as the dopaminergic and serotonergic systems, modulate and are modulated by the formation of the social hierarchy in a group. While these monoamine systems have a wide distribution and multiple functions, it was recently found that the Neuropeptide B/W contributes to the perception of dominance and is present in neurons that have a limited projection primarily to the amygdala. The present review discusses the specific roles of these neural regions and neurotransmitter systems in the perception of dominance and in hierarchy formation. PMID:26136644

[Factors influencing self-perception of overweight people].
Makara-Studzińska, Marta; Podstawka, Danuta; Goclon, Karolina
2013-11-01
Shaping of self-perception is among others influenced by physical, interpersonal, emotional, and cultural factors. In self-perception of overweight people an important role is played by interpersonal factors, which include the opinions of others and the relationship with the surrounding. The evaluation of the body image is also affect by sociocultural factors including the media, which create an unrealistic and impossible to achieve ideal of beauty. Contemporary ideal of beauty, where a slim figure is dominant, more frequently contributes to the occurrence of discrimination and stigmatization of overweight people. This phenomenon causes negative self-perception leading to the occurrence of such emotional problems as low self-esteem, lack of confidence, depression and anxiety disorders. Overweight children and adolescents are also frequently stigmatized and discriminated because of their body weight, which results in the development of a negative body image that may lead to low self-esteem and symptoms of depression.

Full Text Available The issue of young people aged 15–24 that are part of NEET (Not in Education, Employment or Training, is of particular interest for researchers and policy makers, since the social exclusion has strong negative impact on basic needs of persons. Determination of the extent of above social phenomenon is a base for analyses and policy making aiming at coping with it. This paper reports results of 10 years’ dataset analysis concerning the young people aged 15–24 in Macedonia that are part of NEET. Young people who are identified as a NEET are with very high risk of becoming vulnerable group for poverty and social exclusion. The status of these people is more and more important across Europe and their inclusion in the society is a crucial policy goal at European level. Data reported here urge the need for continuous, effective and well targeted support to youth with the aim of providing sustainable inclusion of them in education and labour market. This inclusion requires long term strategies for increasing of youth educational skills, competencies and employability. These strategies have to be focused on effective trainings for performing auxiliary tasks related to the use of emerging technologies that are expected to be dominant in the 21st century, by creating new type of professional education.

BACKGROUND: Alcoholic hepatitis is a form of alcoholic liver disease, characterised by steatosis, necroinflammation, fibrosis, and potential complications to the liver disease. Typically, alcoholic hepatitis presents in people between 40 and 50 years of age. Alcoholic hepatitis can be resolved...... if people abstain from drinking, but the risk of death will depend on the severity of the liver damage and abstinence from alcohol. Glucocorticosteroids are used as anti-inflammatory drugs for people with alcoholic hepatitis. Glucocorticosteroids have been studied extensively in randomised clinical trials...... in order to assess their benefits and harms. However, the results have been contradictory. OBJECTIVES: To assess the benefits and harms of glucocorticosteroids in people with alcoholic hepatitis. SEARCH METHODS: We identified trials through electronic searches in Cochrane Hepato-Biliary's (CHB) Controlled...

Callosal tracts and patterns of hemispheric dominance: a combined fMRI and DTI study.
Häberling, Isabelle S; Badzakova-Trajkov, Gjurgjica; Corballis, Michael C
2011-01-15
Left-hemispheric dominance for language and right-hemispheric dominance for spatial processing are distinctive characteristics of the human brain. However, variations of these hemispheric asymmetries have been observed, with a minority showing crowding of both functions to the same hemisphere or even a mirror reversal of the typical lateralization pattern. Here, we used diffusion tensor imaging and functional magnetic imaging to investigate the role of the corpus callosum in participants with atypical hemispheric dominance. The corpus callosum was segmented according to the projection site of the underlying fibre tracts. Analyses of the microstructure of the identified callosal segments revealed that atypical hemispheric dominance for language was associated with high anisotropic diffusion through the corpus callosum as a whole. This effect was most evident in participants with crowding of both functions to the right. The enhanced anisotropic diffusion in atypical hemispheric dominance implies that in these individuals the two hemispheres are more heavily interconnected. Copyright © 2010 Elsevier Inc.

Women's experiences of important others in a pregnancy dominated by intimate partner violence.
Engnes, Kristin; Lidén, Eva; Lundgren, Ingela
2013-09-01
Being exposed to intimate partner violence (IPV) during pregnancy is a difficult and complex situation. Despite this, there are few studies describing women's own needs for help and support. The aim of this study is to gain a deeper understanding of women's experiences of important others in relation to changing their life situation in a pregnancy dominated by IPV. The study has a qualitative phenomenological design. The data were collected through in-depth interviews with seven Norwegian women, who were exposed to IPV during pregnancy. Being pregnant and exposed to violence in relation to important others means confronting present life, life history and future life. The essence implies striving for control in an uncontrolled situation, where other people might be experienced as both a rescuer and a risk. This is further described in four constitutions: the child needs protection; my mother is always present for me; an exhausted run for help; and a reduced, but important social network. For women exposed to violence, pregnancy can offer an opportunity for change. Midwives play a unique role in relation to care and continuity in this phase of life, as they can support pregnant women, help to identify their needs, possibilities for action and advise them about appropriate services. Midwives can encourage and support women to find people whom they can trust and who can offer assistance. It is vital that midwives ask about the women's relationship to the baby and their social networks, especially the relationship with their mothers. Ethical considerations: During the whole study process, guidelines for research on violence against women were followed, to respect the integrity, security and confidentiality of the participants. The study is ethically approved. © 2012 The Authors. Scandinavian Journal of Caring Sciences © 2012 Nordic College of Caring Science.

Molecular correlates of social dominance: a novel role for ependymin in aggression.
Directory of Open Access Journals (Sweden)
Lynne U Sneddon
2011-04-01
Full Text Available Theoretical and empirical studies have sought to explain the formation and maintenance of social relationships within groups. The resulting dominance hierarchies have significant fitness and survival consequences dependent upon social status. We hypothesised that each position or rank within a group has a distinctive brain gene expression profile that correlates with behavioural phenotype. Furthermore, transitions in rank position should determine which genes shift in expression concurrent with the new dominance status. We used a custom cDNA microarray to profile brain transcript expression in a model species, the rainbow trout, which forms tractable linear hierarchies. Dominant, subdominant and submissive individuals had distinctive transcript profiles with 110 gene probes identified using conservative statistical analyses. By removing the dominant, we characterised the changes in transcript expression in sub-dominant individuals that became dominant demonstrating that the molecular transition occurred within 48 hours. A strong, novel candidate gene, ependymin, which was highly expressed in both the transcript and protein in subdominants relative to dominants, was tested further. Using antibody injection to inactivate ependymin in pairs of dominant and subdominant zebrafish, the subdominant fish exhibited a substantial increase in aggression in parallel with an enhanced competitive ability. This is the first study to characterise the molecular signatures of dominance status within groups and the first to implicate ependymin in control of aggressive behaviour. It also provides evidence for indirect genetic effect models in which genotype/phenotype of an individual is influenced by conspecific interactions within a group. The variation in the molecular profile of each individual within a group may offer a new explanation of intraspecific variation in gene expression within undefined groups of animals and provides new candidates for empirical

Cyclic AMP responsive element-binding protein 3-like 3 (CREB3L3) is a novel candidate gene for dominant hypertriglyceridemia. To date, only 4 kindred with dominant hypertriglyceridemia have been found to be carriers of 2 nonsense mutations in CREB3L3 gene (245fs and W46X). We investigated a family in which hypertriglyceridemia displayed an autosomal dominant pattern of inheritance. The proband was a 49-year-old woman with high plasma triglycerides (≤1300 mg/dL; 14.68 mmol/L). Her father had a history of moderate hypertriglyceridemia, and her 51-year-old brother had triglycerides levels as high as 1600 mg/dL (18.06 mmol/L). To identify the causal mutation in this family, we analyzed the candidate genes of recessive and dominant forms of primary hypertriglyceridemia by direct sequencing. The sequencing of CREB3L3 gene led to the discovery of a novel minute frame shift mutation in exon 3 of CREB3L3 gene, predicted to result in the formation of a truncated protein devoid of function (c.359delG-p.K120fsX20). Heterozygosity for the c.359delG mutation resulted in a severe phenotype occurring later in life in the proband and her brother and a good response to diet and a hypotriglyceridemic treatment. The same mutation was detected in a 13-year-old daughter who to date is normotriglyceridemic. We have identified a novel pathogenic mutation in CREB3L3 gene in a family with dominant hypertriglyceridemia with a variable pattern of penetrance. © 2015 American Heart Association, Inc.

Characteristics and trends of self-harming behaviour in young people.
Cleaver, Karen
Deliberate self-harm is recognized as a serious public health issue in young people. There is evidence that young people who self-harm are more likely to repeat self-harm, and this in turn increases their risk of completed suicide. Prevalence studies have identified that the rate of self-harm among young people is on the increase, information largely based on data arising from review and analysis of hospital attendances. However, community-based studies indicate that the prevalence is much higher, with those seen in emergency departments representing the 'tip of the iceberg' (Hawton and Rodham, 2006). Young people's motives for self-harm are discussed, as are research findings which indicate that nurses can have negative attitudes towards patients who self-harm. The article considers the implications of this for young people and identifies areas for future research.

To describe and compare the perceived social provision for a group reporting never feeling lonely with that of a group reporting feeling lonely and to explore the meaning of loneliness. Participants (N = 101) were recruited from geriatric wards. Inclusion criteria were as follows: aged 65 years or more, the absence of dementia, one or more chronic physical disorders and plans to be discharged from the hospital to their home. The mean age was 81.3 years (range: 65-96 years), 68% were women, and 66% lived alone. Assessments of social provisions and loneliness were collected by a subjective report using the Social Provision Scale (SPS), and the Montgomery-Aasberg Depression Rating Scale (MADRS) was used to assess depression. The participants were also asked whether they felt lonely and were then asked to describe the meaning of loneliness if they had indicated feeling lonely. Narratives were then condensed by the participants into short sentences. Seventy-five per cent of the participants reported feeling lonely, of these 54% were living alone, and 18% identified with depression. Three subscales of SPS scores were significantly lower in the lonely group: attachment (p loneliness was dominated by emptiness and negative emotions. The following themes were identified: Emotions were dominated by sadness, anxiety and restlessness, anger and guilt. Relationships were dominated by being left alone, being confined and feeling useless. Existential dimensions were characterised by emptiness, endless boredom, isolation and the potential for change. The study shows that loneliness is prevalent among older people suffering from chronic physical illness and confirms the complexity of the concept. A mixed-methods design contributed to nuanced and detailed information about the meaning of loneliness. © 2013 Nordic College of Caring Science. Published by Blackwell Publishing Ltd.

Dominant Capital and the New Wars
Directory of Open Access Journals (Sweden)
Shimshon Bichler
2015-08-01
Full Text Available The recent shift from global villageism to the new wars revealed a deep crisis in heterodox political economy. The popular belief in neoliberal globalization, peace dividends, fiscal conservatism and sound finance that dominated the 1980s and 1990s suddenly collapsed. The early 2000s brought rising xenophobia, growing military budgets and policy profligacy. Radicals were the first to identify this transition, but their attempts to explain it have been bogged down by two major hurdles: (1 most writers continue to apply nineteenth century theories and concepts to twenty-first century realities; and (2 few seem to bother with empirical analysis. This paper offers a radical alternative that is both theoretically new and empirically grounded. We use the new wars as a stepping stone to understand a triple transformation that altered the nature of capital, the accumulation of capital and the unit of capital. Specifically, our argument builds on a power understanding of capital that emphasizes differential accumulation by dominant capital groups. Accumulation, we argue, has little to do with the amassment of material things measured in utils or abstract labor. Instead, accumu-lation, or capitalization, represents a commodification of power by leading groups in society. Over the past century, this power has been restructured and concentrated through two distinct regimes of differential accumulationbreadth and depth. A breadth regime relies on proletarianization, on green-field investment and, particularly, on mergers and acquisitions. A depth regime builds on redistribution through stagflationthat is, on differential inflation in the midst of stagnation. In contrast to breadth which presupposes some measure of growth and stability, depth thrives on accumulation through crisis. The past twenty years were dominated by breadth, buttressed by neoliberal rhetoric, globalization and capital mobility. This regime started

Full Text Available This research aims to test the fiscal dominance hypothesis for Pakistan through a bivariate structural vector auto regression (SVAR specification, covering time period 1977 – 2016. This study employs real primary deficit (non interest government expenditures minus total revenues and real primary liabilities (sum of monetary base and domestic public debt as indicators of fiscal measures and monetary policy respectively. A structural VAR is retrieved both for entire sample period and four sub periods (1977 – 1986, 1987 – 1997, 1998 – 2008, and 2009 – 2016. This study identifies the presence of fiscal dominance for the entire sample period and the sub period from 1987 – 2008. The estimates reveal an interesting phenomenon that fiscal dominance is significant in the elected regimes and weaker in the presence of military regimes in Pakistan. From a policy perspective, this research suggests increased autonomy of central bank to achieve long term price stability and reduced administration costs to ensure efficient democratic regime in Pakistan.

The present study examined the effects of reading submission- and dominance-themed erotica on attitudes toward women and rape, ideal partner preferences, and subjective sexual arousal. Heterosexual male (n = 241) and female (n = 240) participants read one of three erotic stories depicting male dominance, female dominance, or no dominance, or a fourth nonerotic control story. First, we found that after reading about a sexually dominant man, women reported increased benevolent sexism compared to men, and men reported increased rape myth acceptance compared to women. Second, men and women showed a similar level of preference for partner dominance after reading about a sexually dominant woman. This was in contrast to the typical pattern revealed in all other conditions, whereby women were more likely to favor dominant partners relative to men. Finally, we found no evidence to support the hypothesis that the story describing male dominance would be the most arousing. Rather, all three erotic stories were equally sexually arousing compared to the control condition, and men and women did not differ in the extent to which the erotic stories aroused them. Theoretical and practical implications are discussed.

Sensation seeking in opium abusers compared to normal people
Directory of Open Access Journals (Sweden)
2004-05-01
Full Text Available Recent research shows that it is possible to identify people at risk of substance abuse using some personality variables. Identification of these people might help social planners to deal with these people specifically in their prevention attempts. The aim of this study was to compare the sensation seeking of opium addicted and non-addicted people using the sensation seeking scale. Such a comparison might help to identify personality variables that are effective in turning toward substance abuse. In order to measure the sensation seeking of subjects “Sensation Seeking Scale” (SSS were used. 31 opium abusers were matched to 31 normal controls according to the following variables: age, education, father and mother education. Results showed that opium abusers obtain higher scores on the total sensation seeking score ,“variety seeking” and “experience seeking” subscales.

Social dominance orientation (SDO) has been theorized as a stable, early-emerging trait influencing outgroup evaluations, a view supported by evidence from cross-sectional and two-wave longitudinal research. Yet, the limitations of identifying causal paths with cross-sectional and two-wave designs are increasingly being acknowledged. This article presents the first use of multi-wave data to test the over-time relationship between SDO and outgroup affect among young people. We use cross-lagged and latent growth modeling (LGM) of a three-wave data set employing Norwegian adolescents (over 2 years, N = 453) and a five-wave data set with American university students (over 4 years, N = 748). Overall, SDO exhibits high temporal rank-order stability and predicts changes in outgroup affect. This research represents the strongest test to date of SDO's role as a stable trait that influences the development of prejudice, while highlighting LGM as a valuable tool for social and political psychology. © 2016 by the Society for Personality and Social Psychology, Inc.

Punctate palmoplantar keratoderma type 1 (PPPK1) is a rare autosomal dominant inherited skin disease, characterized by multiple hyperkeratotic lesions on the palms and soles. The causative gene for PPPK1 has been identified as AAGAB, which encodes α- and γ-adaptin-binding protein p34. We describe the clinical features in three unrelated families with PPPK1, and report three recurrent causative mutations in AAGAB. © 2017 British Association of Dermatologists.

A dominance hierarchy of auditory spatial cues in barn owls.
Directory of Open Access Journals (Sweden)
Ilana B Witten
2010-04-01
Full Text Available Barn owls integrate spatial information across frequency channels to localize sounds in space.We presented barn owls with synchronous sounds that contained different bands of frequencies (3-5 kHz and 7-9 kHz from different locations in space. When the owls were confronted with the conflicting localization cues from two synchronous sounds of equal level, their orienting responses were dominated by one of the sounds: they oriented toward the location of the low frequency sound when the sources were separated in azimuth; in contrast, they oriented toward the location of the high frequency sound when the sources were separated in elevation. We identified neural correlates of this behavioral effect in the optic tectum (OT, superior colliculus in mammals, which contains a map of auditory space and is involved in generating orienting movements to sounds. We found that low frequency cues dominate the representation of sound azimuth in the OT space map, whereas high frequency cues dominate the representation of sound elevation.We argue that the dominance hierarchy of localization cues reflects several factors: 1 the relative amplitude of the sound providing the cue, 2 the resolution with which the auditory system measures the value of a cue, and 3 the spatial ambiguity in interpreting the cue. These same factors may contribute to the relative weighting of sound localization cues in other species, including humans.

Increasing demands are being placed on emergency departments in Australia and there is a view that older Australians are more likely than other age groups to attend for non-urgent conditions. The objective of this paper is to compare and contrast administrative data with the views of hospital staff and older people with regard to their presentation at two emergency departments in metropolitan Adelaide and how this aligns with the Australian Institute of Health and Welfare definition of 'potentially avoidable general practitioner-type presentations'. The study used three sources of data from two emergency departments: hospital data for the financial year 2010-11 for patients aged 65 years and over and identified as triage category four or five; three focus groups with medical, nursing and allied staff from these two hospitals; and interviews with 58 older people who presented at the two emergency departments over a two-week period. The hospital administrative data provided a very limited insight into why older people attended the emergency department, other than the medical diagnosis. Professional staff identified individual determinants, societal determinants and the health services system as explanations. Older people attended the emergency department for a range of reasons that may not necessarily reflect the opinions of health professionals. For many older people the emergency department was an appropriate place to attend considering their condition, though some presentations could be circumvented with appropriate and increased services in the community. However, as many older people suffer comorbidities, careful consideration needs to be given as to the best possible practices to achieve this.

Algal Diet of Small-Bodied Crustacean Zooplankton in a Cyanobacteria-Dominated Eutrophic Lake.
Directory of Open Access Journals (Sweden)
Ilmar Tõnno
Full Text Available Small-bodied cladocerans and cyclopoid copepods are becoming increasingly dominant over large crustacean zooplankton in eutrophic waters where they often coexist with cyanobacterial blooms. However, relatively little is known about their algal diet preferences. We studied grazing selectivity of small crustaceans (the cyclopoid copepods Mesocyclops leuckarti, Thermocyclops oithonoides, Cyclops kolensis, and the cladocerans Daphnia cucullata, Chydorus sphaericus, Bosmina spp. by liquid chromatographic analyses of phytoplankton marker pigments in the shallow, highly eutrophic Lake Võrtsjärv (Estonia during a seasonal cycle. Copepods (mainly C. kolensis preferably consumed cryptophytes (identified by the marker pigment alloxanthin in gut contents during colder periods, while they preferred small non-filamentous diatoms and green algae (identified mainly by diatoxanthin and lutein, respectively from May to September. All studied cladoceran species showed highest selectivity towards colonial cyanobacteria (identified by canthaxanthin. For small C. sphaericus, commonly occuring in the pelagic zone of eutrophic lakes, colonial cyanobacteria can be their major food source, supporting their coexistence with cyanobacterial blooms. Pigments characteristic of filamentous cyanobacteria and diatoms (zeaxanthin and fucoxanthin, respectively, algae dominating in Võrtsjärv, were also found in the grazers' diet but were generally avoided by the crustaceans commonly dominating the zooplankton assemblage. Together these results suggest that the co-occurring small-bodied cyclopoid and cladoceran species have markedly different algal diets and that the cladocera represent the main trophic link transferring cyanobacterial carbon to the food web in a highly eutrophic lake.

Hereditary motor and sensory neuropathy with proximal dominance (HMSN-P) has been reported as a rare type of autosomal dominant adult-onset Charcot-Marie-Tooth disease. HMSN-P has been described only in Japanese descendants since 1997, and the causative gene has not been found. To identify the genetic cause of HMSN-P in a Korean family and determine the pathogenic mechanism. Genetic and observational analysis. Translational research center for rare neurologic disease. Twenty-eight individuals (12 men and 16 women) from a Korean family with HMSN-P. Whole-exome sequencing, linkage analysis, and magnetic resonance imaging. Through whole-exome sequencing, we revealed that HMSN-P is caused by a mutation in the TRK-fused gene (TFG). Clinical heterogeneities were revealed in HMSN-P between Korean and Japanese patients. The patients in the present report showed faster progression of the disease compared with the Japanese patients, and sensory nerve action potentials of the sural nerve were lost in the early stages of the disease. Moreover, tremor and hyperlipidemia were frequently found. Magnetic resonance imaging of the lower extremity revealed a distinct proximal dominant and sequential pattern of muscular involvement with a clearly different pattern than patients with Charcot-Marie-Tooth disease type 1A. Particularly, endoneural blood vessels revealed marked narrowing of the lumen with swollen vesicular endothelial cells. The underlying cause of HMSN-P proves to be a mutation in TFG that lies on chromosome 3q13.2. This disease is not limited to Japanese descendants, and marked narrowing of endoneural blood vessels was noted in the present study. We believe that TFG can affect the peripheral nerve tissue.

Full Text Available This paper is the result of a three-month monitoring of Serbian television commercials which aimed to study the way elderly people are represented in the media. Elderly people appear in only six commercials, more often as a functional part of a series than as protagonists. Yet in spite of the small number of commercials in which they appear, it is easy to identify the stereotypes which are translated from a social paradigm into the sphere of the media. The stereotypes on which commercials are based belong for the most part to the corpus of negative stereotypes of elderly people as hopelessly behind the times, feeble, lonely, irritating, cantankerous, etc. Some positive stereotypes are also evident, but they are mostly limited to a perception of elderly people as kindly givers of useful advice. It is interesting to note that the "cantankerous people next door" are as a rule anonymous elderly people, as are those "lost in time and space", who are mostly elderly women. In contrast, those who let their careers and images be associated with a certain product, in order to pass on their great experience and knowledge, are as a rule famous persons. Just as it is possible to make a distinction between commercials depending on whether or not the products advertised are targeted at the elderly – which they rarely are – and whether elderly people appear in leading or supporting roles, in order to make viewers laugh or annoy them, so it is possible to distinguish between the "real-life principle", which involves the translation of the society’s dominant attitudes into commercials, and "commercial reality", which either makes old age invisible or "masks" it so that it is pleasant to the eye. The reason that old people are absent from television commercials or are mostly represented in a negative light is to be found in the low purchasing power of this age group, but also in the fact that advertising in Serbia developed practically overnight, and

Full Text Available In quantitative genetics, the average effect at a single locus can be estimated by an additive (A model, or an additive plus dominance (AD model. In the presence of dominance, the AD-model is expected to be more accurate, because the A-model falsely assumes that residuals are independent and identically distributed. Our objective was to investigate the accuracy of an estimated average effect (α^ in the presence of dominance, using either a single locus A-model or AD-model. Estimation was based on a finite sample from a large population in Hardy-Weinberg equilibrium (HWE, and the root mean squared error of α^ was calculated for several broad-sense heritabilities, sample sizes, and sizes of the dominance effect. Results show that with the A-model, both sampling deviations of genotype frequencies from HWE frequencies and sampling deviations of allele frequencies contributed to the error. With the AD-model, only sampling deviations of allele frequencies contributed to the error, provided that all three genotype classes were sampled. In the presence of dominance, the root mean squared error of α^ with the AD-model was always smaller than with the A-model, even when the heritability was less than one. Remarkably, in the absence of dominance, there was no disadvantage of fitting dominance. In conclusion, the AD-model yields more accurate estimates of average effects from a finite sample, because it is more robust against sampling deviations from HWE frequencies than the A-model. Genetic models that include dominance, therefore, yield higher accuracies of estimated average effects than purely additive models when dominance is present.

To investigate how older people effectively identify, select and learn to use mobile communications technologies to enhance communication and safety, and support independent living. One hundred and fifty-three older South Australians participated in a purpose-designed survey questionnaire. Older people relied on family and friends for information and advice (76%), and their children's assistance with buying (45%) and learning to use (48%) new technology. The most preferred learning method was face-to-face training (56%). Less than half (44%) were interested in trying out new designs/applications, functions and capabilities that could assist with independent living. The highest need was for personal security and emergencies (88%). Findings suggest that the family and friends of older people play an important role in identifying, selecting and learning to use mobile communication technologies. The safety and emergency capabilities of mobile communications technologies were more important than having functions that could assist with independent living. © 2014 ACOTA.

The prevention of diabetes and cardiovascular disease in people with schizophrenia.
Holt, R I G
2015-08-01
Primary prevention of diabetes and cardiovascular disease is an important priority for people with schizophrenia. This review aims to identify lifestyle and pharmacological interventions that reduce diabetes and cardiovascular disease in people with schizophrenia. PubMed and other electronic databases were searched to identify relevant articles. Lifestyle interventions that focus on diet and physical activity reduce the incidence of diabetes. Similar programmes in people with schizophrenia have led to significant weight loss and may reasonably be expected to reduce diabetes in the long-term. Metformin may be considered when lifestyle change is not feasible or effective. Lifestyle interventions, particularly smoking cessation, are likely to be effective in reducing cardiovascular disease in people with schizophrenia. Although cardiovascular prevention trials with statins have not been performed in people with schizophrenia, similar reductions in cholesterol has been seen as in the general population and statins should be considered for those at high risk. Traditional cardiovascular risk prediction models perform well in identifying those at high cardiovascular risk, but bespoke prediction models using data from people with schizophrenia perform better. Reducing diabetes and cardiovascular disease requires a coordinated and concerted effort from mental and physical health teams working across primary and secondary care. © 2015 John Wiley & Sons A/S.

The relationship between home hazards and falls in older Malaysian people is not yet fully understood. No tools to evaluate the Malaysian home environment currently exist. Therefore, this study aimed to pilot the Home Falls and Accidents Screening Tool (HOME FAST) to identify hazards in Malaysian homes, to evaluate the feasibility of using the HOME FAST in the Malaysian Elders Longitudinal Research (MELoR) study and to gather preliminary data about the experience of falls among a small sample of Malaysian older people. A cross-sectional pilot study was conducted. An urban setting in Kuala Lumpur. 26 older people aged 60 and over were recruited from the control group of a related research project in Malaysia, in addition to older people known to the researchers. The HOME FAST was applied with the baseline survey for the MELoR study via a face-to-face interview and observation of the home by research staff. The majority of the participants were female, of Malay or Chinese ethnicity and living with others in a double-storeyed house. Falls were reported in the previous year by 19% and 80% of falls occurred at home. Gender and fear of falling had the strongest associations with home hazards. Most hazards were detected in the bathroom area. A small number of errors were detected in the HOME FAST ratings by researchers. The HOME FAST is feasible as a research and clinical tool for the Malaysian context and is appropriate for use in the MELoR study. Home hazards were prevalent in the homes of older people and further research with the larger MELoR sample is needed to confirm the validity of using the HOME FAST in Malaysia. Training in the use of the HOME FAST is needed to ensure accurate use by researchers. Published by the BMJ Publishing Group Limited.

Understanding "people" people.
Butler, Timothy; Waldroop, James
2004-06-01
Nearly all areas of business--not just sales and human resources--call for interpersonal savvy. Relational know-how comprises a greater variety of aptitudes than many executives think. Some people can "talk a dog off a meat truck," as the saying goes. Others are great at resolving interpersonal conflicts. Some have a knack for translating high-level concepts for the masses. And others thrive when they're managing a team. Since people do their best work when it most closely matches their interests, the authors contend, managers can increase productivity by taking into account employees' relational interests and skills when making personnel choices and project assignments. After analyzing psychological tests of more than 7,000 business professionals, the authors have identified four dimensions of relational work: influence, interpersonal facilitation, relational creativity, and team leadership. This article explains each one and offers practical advice to managers--how to build a well-balanced team, for instance, and how to gauge the relational skills of potential employees during interviews. To determine whether a job candidate excels in, say, relational creativity, ask her to describe her favorite advertising campaign, slogan, or image and tell you why she finds it to be so effective. Understanding these four dimensions will help you get optimal performance from your employees, appropriately reward their work, and assist them in setting career goals. It will also help you make better choices when it comes to your own career development. To get started, try the authors' free online assessment tool, which will measure both your orientation toward relational work in general and your interest level in each of its four dimensions.

The paradox of helping: Contradictory effects of scaffolding people with aphasia to communicate.
Directory of Open Access Journals (Sweden)

Full Text Available When interacting with people with aphasia, communication partners use a range of subtle strategies to scaffold, or facilitate, expression and comprehension. The present article analyses the unintended effects of these ostensibly helpful acts. Twenty people with aphasia and their main communication partners (n = 40 living in the UK were video recorded engaging in a joint task. Three analyses reveal that: (1 scaffolding is widespread and mostly effective, (2 the conversations are dominated by communication partners, and (3 people with aphasia both request and resist help. We propose that scaffolding is inherently paradoxical because it has contradictory effects. While helping facilitates performing an action, and is thus enabling, it simultaneously implies an inability to perform the action independently, and thus it can simultaneously mark the recipient as disabled.

Graph products have turned out to be a good model of interconnection networks. This motivated us to study the Cartesian product of graphs G with connected domination number, γc(G=2,3 and characterize such graphs. Also, we characterize the k−γ-vertex (edge critical graphs and k−γc-vertex (edge critical graphs for k=2,3 where γ denotes the domination number of G. We also discuss the vertex criticality in grids.

Identifying indicators of illegal behaviour: carnivore killing in human-managed landscapes.
St John, Freya A V; Keane, Aidan M; Edwards-Jones, Gareth; Jones, Lauren; Yarnell, Richard W; Jones, Julia P G
2012-02-22
Managing natural resources often depends on influencing people's behaviour, however effectively targeting interventions to discourage environmentally harmful behaviours is challenging because those involved may be unwilling to identify themselves. Non-sensitive indicators of sensitive behaviours are therefore needed. Previous studies have investigated people's attitudes, assuming attitudes reflect behaviour. There has also been interest in using people's estimates of the proportion of their peers involved in sensitive behaviours to identify those involved, since people tend to assume that others behave like themselves. However, there has been little attempt to test the potential of such indicators. We use the randomized response technique (RRT), designed for investigating sensitive behaviours, to estimate the proportion of farmers in north-eastern South Africa killing carnivores, and use a modified logistic regression model to explore relationships between our best estimates of true behaviour (from RRT) and our proposed non-sensitive indicators (including farmers' attitudes, and estimates of peer-behaviour). Farmers' attitudes towards carnivores, question sensitivity and estimates of peers' behaviour, predict the likelihood of farmers killing carnivores. Attitude and estimates of peer-behaviour are useful indicators of involvement in illicit behaviours and may be used to identify groups of people to engage in interventions aimed at changing behaviour.

Self-determination and older people--a concept analysis.
Ekelund, Christina; Dahlin-Ivanoff, Synneve; Eklund, Kajsa
2014-03-01
Self-determination has emerged as an important concept within health care, used to emphasize clients' control and independence as they participate in rehabilitation. To strengthen clients' self-determination is a central aim in occupational therapy. However, there is a lack of a clear definition of self-determination concerning community-dwelling older people. The definition should be flexible in different contexts, such as cultural. To define and clarify the concept of self-determination in relation to community-dwelling frail older people. Walker & Avant's analysis procedure was carried out to identify textual attributes to the concept of self-determination, supplemented by a content analysis of 21 articles that were used to define and further justify the textual attributes. Self-determination was used in diverse contexts for community-dwelling older people, concerning: decision-making in everyday life, professionals' views, health, and legal/ethical rights. Different textual attributes were identified, to propose a conceptual definition of self-determination in relation to community-dwelling frail older people: A process in which a person has control and legal/ethical rights, and has the knowledge and ability to make a decision of his/her own free choice. This concept analysis has contributed to clarifying the concept for the convenience of research with community-dwelling frail older people.

Full Text Available The combined effect of environment and diet in shaping the gut microbiota remain largely unknown. This knowledge, however, is important for animal welfare and safe food production. For these reasons we determined the effect of experimental units on the chicken caecum microbiota for a full factorial experiment where we tested the combined effect of room, diet and antimicrobial treatment. By Illumina Deep sequencing of the 16S rRNA gene, we found that diet mainly affected the dominant microbiota, while the room as a proxy for environment had major effects on the non-dominant microbiota (p=0.006, Kruskal Wallis test. We therefore propose that the dominant and non-dominant microbiotas are shaped by different experimental units. These findings have implications both for our general understanding of the host-associated microbiota, and for setting up experiments related to specific targeting of pathogens.

The People`s Republic of China (hereafter referred to as China) is the largest producer and consumer of coal in the world. The dominance of coal in China`s energy balance has come at a high price to the environment. With the recent attention given to global warming issues, China`s energy consumption and production practices have become the subject of much concern. Of particular concern is China`s ability to reduce CO{sub 2} emissions by constraining coal use and the impact such policies will likely have on the Chinese economy. The study is divided into two reports. Volume 1 focuses on the full coal fuel cycle, emissions, and environmental effects. This report (Volume 2) analyzes various CO{sub 2} mitigation strategies and determines their effect on economic growth. Contrary to what some analysts have claimed, the current work suggests that it would not be costly for the Chinese to reduce CO{sub 2} emissions. In fact, some strategies were accompanied by increases in China`s energy and economic efficiency, which actually stimulated economic growth.

Genomewide association studies sometimes identify loci at which both the number and identities of the underlying causal variants are ambiguous. In such cases, statistical methods that model effects of multiple SNPs simultaneously can help disentangle the observed patterns of association and provide information about how those SNPs could be prioritized for follow-up studies. Current multi-SNP methods, however, tend to assume that SNP effects are well captured by additive genetics; yet when genetic dominance is present, this assumption translates to reduced power and faulty prioritizations. We describe a statistical procedure for prioritizing SNPs at GWAS loci that efficiently models both additive and dominance effects. Our method, LLARRMA-dawg, combines a group LASSO procedure for sparse modeling of multiple SNP effects with a resampling procedure based on fractional observation weights; it estimates for each SNP the robustness of association with the phenotype both to sampling variation and to competing explanations from other SNPs. In producing a SNP prioritization that best identifies underlying true signals, we show that: our method easily outperforms a single marker analysis; when additive-only signals are present, our joint model for additive and dominance is equivalent to or only slightly less powerful than modeling additive-only effects; and, when dominance signals are present, even in combination with substantial additive effects, our joint model is unequivocally more powerful than a model assuming additivity. We also describe how performance can be improved through calibrated randomized penalization, and discuss how dominance in ungenotyped SNPs can be incorporated through either heterozygote dosage or multiple imputation.

Consumers, health insurance and dominated choices.
Sinaiko, Anna D; Hirth, Richard A
2011-03-01
We analyze employee health plan choices when the choice set offered by their employer includes a dominated plan. During our study period, one-third of workers were enrolled in the dominated plan. Some may have selected the plan before it was dominated and then failed to switch out of it. However, a substantial number actively chose the dominated plan when they had an unambiguously better choice. These results suggest limitations in the ability of health reform based solely on consumer choice to achieve efficient outcomes and that implementation of health reform should anticipate, monitor and account for this consumer behavior.

Whole-exome sequencing identifies USH2A mutations in a pseudo-dominant Usher syndrome family.
Zheng, Sui-Lian; Zhang, Hong-Liang; Lin, Zhen-Lang; Kang, Qian-Yan
2015-10-01
Usher syndrome (USH) is an autosomal recessive (AR) multi-sensory degenerative disorder leading to deaf-blindness. USH is clinically subdivided into three subclasses, and 10 genes have been identified thus far. Clinical and genetic heterogeneities in USH make a precise diagnosis difficult. A dominant‑like USH family in successive generations was identified, and the present study aimed to determine the genetic predisposition of this family. Whole‑exome sequencing was performed in two affected patients and an unaffected relative. Systematic data were analyzed by bioinformatic analysis to remove the candidate mutations via step‑wise filtering. Direct Sanger sequencing and co‑segregation analysis were performed in the pedigree. One novel and two known mutations in the USH2A gene were identified, and were further confirmed by direct sequencing and co‑segregation analysis. The affected mother carried compound mutations in the USH2A gene, while the unaffected father carried a heterozygous mutation. The present study demonstrates that whole‑exome sequencing is a robust approach for the molecular diagnosis of disorders with high levels of genetic heterogeneity.

Full Text Available Introduction: Sufficient high quality dietary protein intake is required to prevent or treat sarcopenia in elderly people. Therefore, the intake of specific protein sources as well as their timing of intake are important to improve dietary protein intake in elderly people. Objectives: to assess the consumption of protein sources as well as the distribution of protein sources over the day in community-dwelling, frail and institutionalized elderly people. Methods: Habitual dietary intake was evaluated using 2- and 3-day food records collected from various studies involving 739 community-dwelling, 321 frail and 219 institutionalized elderly people. Results: Daily protein intake averaged 71 ± 18 g/day in community-dwelling, 71 ± 20 g/day in frail and 58 ± 16 g/day in institutionalized elderly people and accounted for 16% ± 3%, 16% ± 3% and 17% ± 3% of their energy intake, respectively. Dietary protein intake ranged from 10 to 12 g at breakfast, 15 to 23 g at lunch and 24 to 31 g at dinner contributing together over 80% of daily protein intake. The majority of dietary protein consumed originated from animal sources (≥60% with meat and dairy as dominant sources. Thus, 40% of the protein intake in community-dwelling, 37% in frail and 29% in institutionalized elderly originated from plant based protein sources with bread as the principle source. Plant based proteins contributed for >50% of protein intake at breakfast and between 34% and 37% at lunch, with bread as the main source. During dinner, >70% of the protein intake originated from animal protein, with meat as the dominant source. Conclusion: Daily protein intake in these older populations is mainly (>80% provided by the three main meals, with most protein consumed during dinner. More than 60% of daily protein intake consumed is of animal origin, with plant based protein sources representing nearly 40% of total protein consumed. During dinner, >70% of the protein intake originated from

Full Text Available To examine when the manufacturer and dominant retailer open their own Internet stores and how setting prices to ensure opening Internet stores are profitable. We consider a two-echelon supply chain with one manufacturer and one dominant retailer. The retailer has a physical store in a monopolist market. Depending on whether the Internet stores are opened successfully by them, we firstly obtain equilibrium prices and profits under four possible supply chain structures. Secondly, we identify several strategic conditions when it is optimal to open an Internet store for the manufacturer and dominant retailer and discuss its implications. It is interesting to note that multichannel retailing is not necessarily the best strategy for the dominant retailer. In addition, we investigate the impacts of problem parameters (the dominant retailer’s bargaining power and consumers’ disutility of purchasing a product from Internet store on the manufacturer and dominant retailer’s pricing policies. We find that the manufacturer’s optimal price at her Internet store is not always being lower than the dominant retailer’s. Finally, we conduct numerical examples to illustrate the theoretical results.

2009-01-01
Identification of the language dominant hemisphere is important in cases necessary for partial encephalotomy due to epilepsy and tumor. Functional MRI (fMRI) essentially detects oxy-Hb/deoxy-Hb ratio in the brain region resulted from blood flow change and near-infrared spectroscopy (NIRS), the Hb level change in the tissue, in which the image can be detected by light-receiving proves of NIR-light (780-1500 nm wavelength) irradiated and passed through the tissues. This paper describes the comparison of the two methods for determination of language dominance with reference to that identified by Wada test, a gold standard but inconvenient for both operators and patients. Subjects are 11 brain tumor and 11 epilepsy patients (M 10/F 12, av. age of 36.7 y, 19 right-handed), whose dominances are successfully determined previously by Wada test. fMRI is conducted with 3T machine (General Electric, USA) with phased-array coil in patients receiving various language tasks, and data are processed by Dr. View (Asahi Kasei) to calculate the laterality index for the dominance. NIRS is conducted with Hitachi-Medico ETG-4000 with 695 and 830 nm IR in patients receiving other different language tasks, on whose frontotemporal region of head surface 12-channel probes are equipped. Data are processed by the equipped software to calculate the difference of oxy-Hb change rates between the two hemispheres for the dominance determination. Consistency of fMRI in determining the dominance with Wada test is found 86.3% and of NIRS, 72.7%, which suggests the latter can be only supplementary to the former. However, NIRS is noted to be useful in atypical cases like those with right or bilateral dominance. (K.T.)

Previous studies have found that transgender, lesbian, and bisexual people report poorer mental health relative to heterosexuals. However, available research provides little information about mental health service access among the highest need groups within these communities: bisexual women and transgender people. This study compared past year unmet need for mental health care and untreated depression between four groups: heterosexual cisgender (i.e., not transgender) women, cisgender lesbians, cisgender bisexual women, and transgender people. This was a cross-sectional Internet survey. We used targeted sampling to recruit 704 sexual and gender minority people and heterosexual cisgendered adult women across Ontario, Canada. To ensure adequate representation of vulnerable groups, we oversampled racialized and low socioeconomic status (SES) women. Trans participants were 2.4 times (95% confidence intervals [CI] = 1.6-3.8, p mental healthcare as cisgender heterosexual women. Trans participants were also 1.6 times (95% CI = 1.0-27, p = 0.04) more likely to report untreated depression. These differences were not seen after adjustment for social context factors such as discrimination and social support. We conclude that there are higher rates of unmet need and untreated depression in trans and bisexual participants that are partly explained by differences in social factors, including experiences of discrimination, lower levels of social support, and systemic exclusion from healthcare. Our findings suggest that the mental health system in Ontario is not currently meeting the needs of many sexual and gender minority people.

Perceptions of sex education for young people in Lesotho.
Mturi, Akim J; Hennink, Monique M
2005-03-01
This study aimed to identify the views of young people, parents and teachers concerning sex education in Lesotho. It was conducted at a time when the national government was considering the introduction of Population and Family Life Education, which includes sex education, into the national school curriculum. Forty-six focus group discussions were held with young people (10), parents (30) and teachers (6) to identify current sources of sex education and views of the proposed introduction of school-based sex education in Lesotho. Findings show the limited and problematic sources of sex education for adolescents in Lesotho. They also highlight broad support for the introduction of sex education in the national school curriculum among young people, parents and teachers. Of key importance for the development of a sex education curriculum is the balance between providing young people with information and developing their skills in sexual empowerment and negotiating sexual pressure. The use of pupil-centred interactive pedagogies was seen as essential. Teachers, however, highlighted the need for training in the delivery of sex education, which includes instruction on course materials, teaching methodologies and developing sensitivity to teaching sexual issues to young people.

We identify the Dresselhaus spin-orbit coupling as the source of the dominant spin-relaxation mechanism in the impurity band of a wide class of n-doped zinc blende semiconductors. The Dresselhaus hopping terms are derived and incorporated into a tight-binding model of impurity sites, and they are shown to unexpectedly dominate the spin relaxation, leading to spin-relaxation times in good agreement with experimental values. This conclusion is drawn from two complementary approaches: an analytical diffusive-evolution calculation and a numerical finite-size scaling study of the spin-relaxation time.

The main signs of ageing in people with intellectual disability.
Wark, Stuart; Hussain, Rafat; Edwards, Helen
2016-12-01
Investigations around ageing with an intellectual disability have increased substantially in the past three decades. A research gap continued to exist regarding the detection of ageing issues in this cohort of people, particularly in rural areas where access to specialist support continued to be limited. The purpose of this study was to identify the main signs of ageing in rural people with intellectual disabilities. A multi-round Delphi design was used to examine what signs of ageing were observed by disability support staff, who assisted people with intellectual disability. The project was conducted across nine of the ten rural regions (as defined by the government funding body) in New South Wales (NSW). There were 31 participants representing 14 non-government organisations. The group was composed of 26 women and 5 men, with a mean age of 47 years, who averaged 10-year experience with people with intellectual disabilities. The objective was to gain the direct input of rurally based disability workers to identify the main signs of ageing in people with intellectual disabilities. Thirty-two specific signs of ageing, including emerging mental health issues, grief, loss of identity and aggression, were identified. A thematic analysis indicated two main categories: mental/emotional functioning and physical functioning. When carers have the information and skills needed to identify the main signs of ageing, they can more accurately recognise and address potential problems in a timely manner. Such understandings have the potential to reduce premature admissions to residential aged-care. © 2016 National Rural Health Alliance Inc.

Human and peoples' rights: social representations among Cameroonian students.
Pirttilä-Backman, Anna-Maija; Kassea, Raul; Sakki, Inari
2009-12-01
Social representations of human and peoples' rights were studied among Cameroonian university students (N = 666) with a questionnaire based on the UN Declaration of Human Rights and the African Charter on Human and Peoples' Rights and Duties. The respondents were asked how important and how well realized they regarded the 39 human and peoples' rights to be. A 13-factor model provided the best fit with Cameroonian students' perceptions of human and peoples' rights. Taken as a whole, our results are in line with previous quantitative studies on human rights, confirming structural similarity but also country-specific variation in the aggregation of specific rights. Moreover, our data showed that Cameroonian students value human and peoples' rights highly (M = 6.18), whereas their fulfillment is not regarded as highly (M = 5.09). Same law for all, equality and freedom, and right to work and living were highly appreciated but lowly realized rights. Higher than average in importance and realization were right to education and self-fulfillment, right to marriage and property, peoples' social and political basic rights and right to life and safety. Low in importance and realization were peoples' right to their country's natural resources and independence, right to meetings, and right to express opinion. Women appreciated the rights more than men and thought of their rights as better realized compared to men. We suggest that when women say that their rights are better fulfilled than men do, it is in comparison with the older generation, who are still very dependent on men. Nowadays, thanks to education and urbanization, young women have wider choices or opportunities for marriage and jobs. Men may feel frustrated in the context of political liberalization because the freedoms are more theoretical than fulfilled; the economic crises and cultural changes have hindered their economic domination and their prerogatives.

Full Text Available Objective: The aim of this study was to compare the plantar pressure distribution of dominant and non-dominant legs of females who were participated in the kata and kumite national team. Methods: Twelve kumite and 8 kata female athletes of the Karate national team participated in this study. Plantar pressure was measured using emed platform during barefoot walking. After dividing the foot into 10 masks, peak pressure, pressure-time integral, maximum force and force-time integral were calculated. Wilcoxon and U-Mann-Witney tests were used to analyze parameters at a significance level of p ≤ 0.05. Results: In comparison of kata and kumite teams it was found that, kata plantar pressure parameters in Metatarsal-2 (p=0.05 and Metatarsals-3, 4, 5 (p=0.04 were significantly less than those in kumite. Also, in comparison of dominant and non-dominant leg, plantar pressure parameters of dominant leg were less in Metatarsal-2 (p=0.04 and more in Bigtoe (p=0.04 and Toes-3, 4, 5 (p=0.03 than those in the non-dominant leg. Conclusion: Results may be indicative different of natures of the two athletic fields in that Kumite has a higher impact on plantar pressure due to higher mechanical loads. Furthermore, the unequal use of the legs may affect plantar pressure because of leg dominance. Thus, further and more comprehensive studies are necessary to prevent exercise-induced adaptations in professional levels and their treatments.

Praise for regret: People value regret above other negative emotions.
Saffrey, Colleen; Summerville, Amy; Roese, Neal J
2008-03-01
What do people think about the emotion of regret? Recent demonstrations of the psychological benefits of regret have been framed against an assumption that most people find regret to be aversive, both when experienced but also when recalled later. Two studies explored lay evaluations of regret experiences, revealing them to be largely favorable rather than unfavorable. Study 1 demonstrated that regret, but not other negative emotions, was dominated by positive more than negative evaluations. In both studies 1 and 2, although participants saw a great deal of benefit from their negative emotions, regret stood out as particularly beneficial. Indeed, in study 2, regret was seen to be the most beneficial of 12 negative emotions on all five functions of: making sense of past experiences, facilitating approach behaviors, facilitating avoidance behaviors, gaining insights into the self, and in preserving social harmony. Moreover, in study 2, individuals made self-serving ascriptions of regret, reporting greater regret experiences for themselves than for others. In short, people value their regrets substantially more than they do other negative emotions.

Beam halo formation from space-charge dominated beams in uniform focusing channels
International Nuclear Information System (INIS)
O'Connell, J.S.; Wangler, T.P.; Mills, R.S.; Crandall, K.R.
1993-01-01
In space-charge dominated beams the nonlinear space-charge forces produce a filamentation pattern, which results in a 2-component beam consisting of an inner core and an outer halo. The halo is very prominent in mismatched beams, and the potential for accelerator activation is of concern for a next generation of cw, high-power proton linacs that could be applied for intense neutron generators to process nuclear materials. We present new results about beam halo and the evolution of space-charge dominated beams from multiparticle simulation of initial laminar beams in a uniform linear focusing channel, and from a model consisting of single particle interactions with a uniform-density beam core. We study the energy gain from particle interactions with the space-charge field of the core, and we identify the resonant characteristic of this interaction as the basic cause of the separation of the beam into the two components. We identify three different particle-trajectory types, and we suggest that one of these types may lead to continuous halo growth, even after the halo is removed by collimators

Hypothalamic digoxin, hemispheric chemical dominance, and eating behavior.
Kurup, Ravi Kumar; Kurup, Parameswara Achutha
2003-08-01
The isoprenoid pathway produces an endogenous membrane Na+-K+ ATPase inhibitor, digoxin, which can regulate neurotransmitter and amino acid transport. Digoxin synthesis and neurotransmitter patterns were assessed in eating disorders. The patterns were compared in those with right hemispheric and left hemispheric dominance. The serum HMG CoA reductase activity, RBC membrane Na+-K+ ATPase activity, serum digoxin, magnesium, tryptophan catabolites (serotonin, quinolinic acid, strychnine, and nicotine), and tyrosine catabolites (morphine, dopamine, and noradrenaline) were measured in anorexia nervosa, bulimia nervosa, right hemispheric dominant, left hemispheric dominant, and bihemispheric dominant individuals. Digoxin synthesis was increased with upregulated tryptophan catabolism and downregulated tyrosine catabolism in those with anorexia nervosa and right hemispheric chemical dominance. Digoxin synthesis was reduced with downregulated tryptophan catabolism and upregulated tyrosine catabolism in those with bulimia nervosa and left hemispheric chemical dominance. The membrane Na+-K+ ATPase activity and serum magnesium were decreased in anorexia nervosa and right hemispheric chemical dominance while they were increased in bulimia nervosa and left hemispheric chemical dominance. Hypothalamic digoxin and hemispheric chemical dominance play a central role in the regulation of eating behavior. Anorexia nervosa represents the right hemispheric chemically dominant/hyperdigoxinemic state and bulimia nervosa the left hemispheric chemically dominant/hypodigoxinemic state.

Do axes of rotation change during fast and slow motions of the dominant and non-dominate arms?
Directory of Open Access Journals (Sweden)
Pagano Christopher
2011-12-01
Full Text Available The velocity-dependent change in rotational axes observed in the control of unconstrained 3D arm rotations for the dominant limb seems to conform to a minimum inertia resistance (MIR principle [4]. This is an efficient biomechanical solution that allows for the reduction of torques. We tested whether the MIR principle governs rotating movement when subjects were instructed to maintain the shoulder-elbow joint axis close to horizontal for both dominant and non dominant limbs. Subjects (n=12 performed externalinternal rotations of their arms in two angular positions (90° versus 150°, two angular velocities (slow (S versus fast (F, and in two sensory conditions (kinaesthetic (K versus visuo- kinaesthetic (VK. We expected more scattered displacements of the rotation axis employed for rotating the non dominant limb compared to the dominant limb. The results showed that the rotational axis of a multiarticulated limb coincided with SH-EL at S & F velocity for both arms.

Background This study tested whether the 2D face evaluation model proposed by Oosterhof and Todorov can parsimoniously account for why some faces are perceived as more criminal-looking than others. The 2D model proposes that trust and dominance are spontaneously evaluated from features of faces. These evaluations have adaptive significance from an evolutionary standpoint because they indicate whether someone should be approached or avoided. Method Participants rated the emotional state, personality traits, and criminal appearance of faces shown in photographs. The photographs were of males and females taken under naturalistic conditions (i.e., police mugshots) and highly controlled conditions. In the controlled photographs, the emotion display of the actor was systematically varied (happy expression, emotionally neutral expression, or angry expression). Results Both male and female faces rated high in criminal appearance were perceived as less trustworthy and more dominant in police mugshots as well as in photographs taken under highly controlled conditions. Additionally, emotionally neutral faces were deemed as less trustworthy if they were perceived as angry, and more dominant if they were morphologically mature. Systematically varying emotion displays also affected criminality ratings, with angry faces perceived as the most criminal, followed by neutral faces and then happy faces. Conclusion The 2D model parsimoniously accounts for criminality perceptions. This study extends past research by demonstrating that morphological features that signal high dominance and low trustworthiness can also signal high criminality. Spontaneous evaluations regarding criminal propensity may have adaptive value in that they may help us to avoid someone who is physically threatening. On the other hand, such evaluations could inappropriately influence decision making in criminal identification lineups. Hence, additional research is needed to discover whether and how people can avoid

Cardiac fibrillation is a major clinical and societal burden. Rotors may drive fibrillation in many cases, but their role and patterns are often masked by complex propagation. We used Singular Value Decomposition (SVD), which ranks patterns of activation hierarchically, together with Wiener-Granger causality analysis (WGCA), which analyses direction of information among observations, to investigate the role of rotors in cardiac fibrillation. We hypothesized that combining SVD analysis with WGCA should reveal whether rotor activity is the dominant driving force of fibrillation even in cases of high complexity. Optical mapping experiments were conducted in neonatal rat cardiomyocyte monolayers (diameter, 35 mm), which were genetically modified to overexpress the delayed rectifier K+ channel IKr only in one half of the monolayer. Such monolayers have been shown previously to sustain fast rotors confined to the IKr overexpressing half and driving fibrillatory-like activity in the other half. SVD analysis of the optical mapping movies revealed a hierarchical pattern in which the primary modes corresponded to rotor activity in the IKr overexpressing region and the secondary modes corresponded to fibrillatory activity elsewhere. We then applied WGCA to evaluate the directionality of influence between modes in the entire monolayer using clear and noisy movies of activity. We demonstrated that the rotor modes influence the secondary fibrillatory modes, but influence was detected also in the opposite direction. To more specifically delineate the role of the rotor in fibrillation, we decomposed separately the respective SVD modes of the rotor and fibrillatory domains. In this case, WGCA yielded more information from the rotor to the fibrillatory domains than in the opposite direction. In conclusion, SVD analysis reveals that rotors can be the dominant modes of an experimental model of fibrillation. Wiener-Granger causality on modes of the rotor domains confirms their

Full Text Available The central feature of Athenian citizens' rights, that is, people's participation in government, is also enshrined in the South African Constitution. This article argues for the Athenian style of participatory democracy as a viable model of participation in governing South African schools. The author claims that 'people's education', which had its origins in the principles of the Freedom Charter¹ - was diluted during the negotiationsfor South Africa's new democratic government. As a result, the political and educational ideal of 'people's education for 'people's power' has given way to democratic elitism in post-apartheid South African schools.

Full Text Available Cardiovascular problem is one of the leading cause of death in Malaysia and now invaded to the sub-urban and rural areas. To prevent and control of this problem, several main risk factors needed to be known and shall be reexamined and ranked according to the priority. The objectives of this research paper was to identify several dominant risk factor related to cardiovascular problem. A cross sectional study was carried out from March 2000 – June 2001 on a total of 8159 rural population aged 18 and above to measure the prevalence of the common cardiovascular risk factors. Those risk factors are systolic blood pressure, diastolic blood pressure, serum cholesterol level, obesity index, blood glucose level, smoking, physical activity and mental stress. Overall prevalence of common cardiovascular risk factors were higher, dominated by physical inactivity (65.7%, hypercholesterolemia – TC:HC (62.3%, mental stress (55.5% and obesity (53.7%. Smoking was also high at 49.9% especially among men. However systolic hypertension, diastolic hypertension and diabetes mellitus; although increased by age, its prevalence is relatively low at 23.7%, 19.2%, and 6.3% respectively. Cardiovascular risk factors related to lifestyle are much evidenced as compared to risk factors related to the biological influence. Therefore, all initiatives in community health intervention should be mobilized specifically on prevention and control of lifestyle-related risk factors.

Forecasting cyanobacteria dominance in Canadian temperate lakes.
Persaud, Anurani D; Paterson, Andrew M; Dillon, Peter J; Winter, Jennifer G; Palmer, Michelle; Somers, Keith M
2015-03-15
Predictive models based on broad scale, spatial surveys typically identify nutrients and climate as the most important predictors of cyanobacteria abundance; however these models generally have low predictive power because at smaller geographic scales numerous other factors may be equally or more important. At the lake level, for example, the ability to forecast cyanobacteria dominance is of tremendous value to lake managers as they can use such models to communicate exposure risks associated with recreational and drinking water use, and possible exposure to algal toxins, in advance of bloom occurrence. We used detailed algal, limnological and meteorological data from two temperate lakes in south-central Ontario, Canada to determine the factors that are closely linked to cyanobacteria dominance, and to develop easy to use models to forecast cyanobacteria biovolume. For Brandy Lake (BL), the strongest and most parsimonious model for forecasting % cyanobacteria biovolume (% CB) included water column stability, hypolimnetic TP, and % cyanobacteria biovolume two weeks prior. For Three Mile Lake (TML), the best model for forecasting % CB included water column stability, hypolimnetic TP concentration, and 7-d mean wind speed. The models for forecasting % CB in BL and TML are fundamentally different in their lag periods (BL = lag 1 model and TML = lag 2 model) and in some predictor variables despite the close proximity of the study lakes. We speculate that three main factors (nutrient concentrations, water transparency and lake morphometry) may have contributed to differences in the models developed, and may account for variation observed in models derived from large spatial surveys. Our results illustrate that while forecast models can be developed to determine when cyanobacteria will dominate within two temperate lakes, the models require detailed, lake-specific calibration to be effective as risk-management tools.

Evidence-based practice relies on clinicians to translate research evidence for individual clients. This study, the initial phase of a broader research project, examines the textual resources of such translations by analyzing how people with acquired cognitive-communication disorders (ACCD) and their life worlds have been represented in Communication Sciences and Disorders (CSD) research articles. Using textual analysis, we completed a categorical analysis of 6,059 articles published between 1936 and 2012, coding for genre, population, and any evidence of thick representations of people and their life worlds, and a discourse analysis of representations used in 56 ACCD research articles, identifying thin and thick representations in 4 domains (derived from the International Classification of Functioning, Disability, and Health) and across article sections. The categorical analysis identified a higher percentage of ACCD articles with some evidence of thick representation (30%) compared with all CSD articles (12%) sampled. However, discourse analysis of ACCD research articles found that thick representations were quite limited; 34/56 articles had thin representational profiles, 19/56 had mixed profiles, and 3/56 had thick profiles. These findings document the dominance of thin representations in the CSD literature, which we suggest makes translational work more difficult. How clinicians translate such evidence will be addressed in the next research phase, an interview study of speech-language pathologists.

Narcissism, Bullying, and Social Dominance in Youth: A Longitudinal Analysis.
Reijntjes, Albert; Vermande, Marjolijn; Thomaes, Sander; Goossens, Frits; Olthof, Tjeert; Aleva, Liesbeth; Van der Meulen, Matty
2016-01-01
A few previous studies have shown that narcissistic traits in youth are positively associated with bullying. However, research examining the developmental relationship between narcissism and bullying is lacking. Moreover, it is unclear whether narcissists constitute a homogeneous group and whether the bullying of narcissistic youth results in establishing social dominance over peers. The present work addresses these gaps. Children (N = 393; M age = 10.3; 51% girls) were followed during the last 3 years of primary school. Person-centered analyses were used to examine whether groups with distinct developmental trajectories for narcissism and two bullying forms (direct and indirect) can be identified, and how these trajectories are related. Multiple groups emerged for all constructs examined. For girls, higher narcissism was neither related to more intense bullying, nor to higher social dominance. In contrast, highly narcissistic boys were more likely than their peers to show elevated direct bullying, and in particular elevated indirect bullying. Hence, high narcissism is a risk factor for bullying in boys, but not in girls. However, narcissism is not always accompanied by high bullying, given that many boys on the high bullying trajectories were not high in narcissism. Results show that among narcissistic youth only those who engage in high levels of bullying are high in social dominance.

Most research links (racial) essentialism to negative intergroup outcomes. We propose that this conclusion reflects both a narrow conceptual focus on biological/genetic essence and a narrow research focus from the perspective of racially dominant groups. We distinguished between beliefs in biological and cultural essences, and we investigated the implications of this distinction for support of social justice policies (e.g., affirmative action) among people with dominant (White) and subordinated (e.g., Black, Latino) racial identities in the United States. Whereas, endorsement of biological essentialism may have similarly negative implications for social justice policies across racial categories, we investigated the hypothesis that endorsement of cultural essentialism would have different implications across racial categories. In Studies 1a and 1b, we assessed the properties of a cultural essentialism measure we developed using two samples with different racial/ethnic compositions. In Study 2, we collected data from 170 participants using an online questionnaire to test the implications of essentialist beliefs for policy support. Consistent with previous research, we found that belief in biological essentialism was negatively related to policy support for participants from both dominant and subordinated categories. In contrast, the relationship between cultural essentialism and policy support varied across identity categories in the hypothesized way: negative for participants from the dominant category but positive for participants from subordinated categories. Results suggest that cultural essentialism may provide a way of identification that subordinated communities use to mobilize support for social justice.

Young people who are being bullied - do they want general practice support?
Scott, Emma; Dale, Jeremy; Russell, Rachel; Wolke, Dieter
2016-08-22
Childhood bullying is a major risk factor for health, education and social relationships, with effects persisting into adulthood. It affects half of all children at some point, with 10-14 % experiencing bullying that lasts for years. With the advent of cyberbullying, it can happen at all times and places. There have been calls for GPs to take a more active role in identifying and supporting young people who are being bullied. This paper explores young people's and parents' opinions about whether general practice should be involved in identifying and supporting young people who are being bullied. Two hundred six young people (85.9 % female, mean ± sd age 16.2 ± 3.2 years) and 44 parents were recruited through established bullying charity websites and their social media channels to complete an online questionnaire comprising multiple-choice questions and unlimited narrative responses. Questionnaire responses were analysed by age and gender using descriptive statistics. A descriptive analysis of the narrative responses was undertaken and key themes identified. Young people (90.8 %) and parents (88.7 %) thought it was important for GPs to be better able to recognise and help young people who are being bullied. Most recognised the link between bullying and health. The doctor's independence was seen as advantageous. Young people preferred completing a screening questionnaire to disclose experience of being bullied than being asked directly. They expressed concerns about how questions would be asked and whether information would be shared with parents/guardians. Parents were supportive of the use of a screening questionnaire, and most expected their child's disclosure to be shared with them. Young people and parents recruited through anti-bullying websites and social media would welcome greater GP involvement in identifying and supporting young people who are being bullied and their families, provided it is offered in a caring, compassionate and

The aims of our study were to compare the dominant (DOM) and non-dominant (NDOM) shoulders of high-level volleyball athletes and identify possible associations of shoulder adaptations with spike speed (SS) and shoulder pathology. A total of 22 male volleyball players from two teams participating in the first division of the Cypriot championship underwent clinical shoulder tests and simple measurements around their shoulder girdle joints bilaterally. SS was measured with the use of a sports speed radar. Compared with the NDOM side, the DOM scapula was more lateralised, the DOM dorsal capsule demonstrated greater laxity, the DOM dorsal muscles stretching ability was compromised, and the DOM pectoralis muscle was more lengthened. Players with present or past DOM shoulder pain demonstrated greater laxity in their DOM dorsal capsule, tightening of their DOM inferior capsule, and lower SS compared with those without shoulder pain. Dorsal capsule measurements bilaterally were significant predictors of SS. None of the shoulder measurements was associated with team roles or infraspinatus atrophy, while scapular lateralisation was more pronounced with increasing years of experience, and scapular antetilting was greater with increasing age. Adaptations of the DOM shoulder may be linked to pathology and performance. We describe simple shoulder measurements that may have the potential to predict chronic shoulder injury and become part of injury prevention programmes. Detailed biomechanical and large prospective studies are warranted to assess the validity of our findings and reach more definitive conclusions.

Maintaining independent mobility is fundamental to independent living and to the quality of life of older people. Robotic and sensor technologies may offer a lot of potential and can make a significant difference in the lives of older people and to their primary caregivers. The aim of this study was to provide a presentation of the methods that are used up till now for analysis and evaluation of human mobility utilizing sensor technologies and to give the state of the art in robotic platforms for supporting older people with mobility limitations. The literature was reviewed and systematic reviews of cohort studies and other authoritative reports were identified. The selection criteria included (1) patients with age ≥60 years; (2) patients with unstable gait, with or without recurrent falls; (3) patients with slow movements, short strides, and little trunk movement; (4) sensor technologies that are currently used for mobility evaluation; and (5) robotic technologies that can serve as a supporting companion for older people with mobility limitations. One hundred eighty-one studies published up until February 2017 were identified, of which 36 were included. Two categories of research were identified from the review regarding the robot and sensor technologies: (1) sensor technologies for mobility analysis and (2) robots for supporting older people with mobility limitations. Potential for robotic and sensor technologies can be taken advantage of for evaluation and support at home for elder persons with mobility limitations in an automated way without the need of the physical presence of any medical personnel, reducing the stress of caregivers.

Full Text Available Problem Statement: The aim of this study was to compare the ball velocity in different kicking conditions with dominant and non-dominant leg in junior soccer players.Approach: Sixteen junior soccer players (age 17.6±0.6yr, height 1.76±0.06m, and weight 67.9±5.2kg participated in this study. All participants kicked a soccer ball three times in seven conditions with the dominant and non-dominant leg. 1 Kicking the ball from 11m straight forwards, 2 and 3 kicking the ball from 11m to the left and right side of the goal, 4 and 5 kicking the ball straight forwards from 11m after a pass from the left and right side, 6 and 7 kicking the ball straight forwards from 11m after a pass that came from a diagonal position (45º from the left and right side. The highest ball velocity was used for analysis.Results: Significant differences were found in ball velocity between the dominant and non-dominant leg in all conditions (p<0.001. For the dominant leg also significant differences were found in the kicking of eleven meters (ideal conditions compared with: the perpendicular passing kick after the ball on the right (p=0.0024 and left (p=0.0080 and also with a diagonal kick after pass (45 ° of the ball on the right (p=0.0017 and left (p = 0.0381. Significant differences in the kicking with the non-dominant leg were found when kicking from eleven meters to the right side of the goal in comparison to: the kick under the same conditions, to the left side of the goal (p=0.0243 after pass and shot from the left side perpendicular (p=0.0222.Conclusions/Recommendations: kicking velocity is influenced very much under different conditions when kicking with the dominant leg while for the non-dominant leg this influence was small, because the non-dominant leg is less trained, so the values of velocity in different conditions, in addition to being the lowest, are closer than those obtained with the dominant leg

Barriers and facilitators to mobile phone use for people with aphasia.
Greig, Carole-Ann; Harper, Renée; Hirst, Tanya; Howe, Tami; Davidson, Bronwyn
2008-01-01
Mobile phone use increases social participation. People with the communication disorder of aphasia are disadvantaged in the use of information and communication technology such as mobile phones and are reported to be more socially isolated than their peers. The World Health Organization's International Classification of Functioning, Disability and Health provides a framework to address the impact of environmental factors on individual participation. The aim of this preliminary study was to identify the barriers and facilitators to mobile phone use for people with aphasia. A qualitative descriptive study involving two phases was conducted: (1) semi-structured interviews with 6 individuals with aphasia who owned or expressed a desire to own a mobile phone; (2) structured observations of key scenarios identified in the interviews of 3 participants who were sampled from the interview study. Results identified 18 barriers and 9 facilitators to mobile phone use. Key barriers and facilitators were identified in the areas of design and features, written support and training, and communicative partners. Mobile phone use can be problematic for people with aphasia. Intervention needs to address the barriers and utilise the facilitators to mobile phone use for this population. Further research is required to inform policy and intervention programs to ensure that people with aphasia have access to this technology.

A framework within sexual and reproductive health is presented to understand the mental health issues of the population of lesbian, gay and bisexual (LGB) adolescents and young people. Different ways of understanding the nature of internalized homophobia were developed. On the other hand, in suicidology studies it is understood that the risk of suicide consists of the steps of ideation, planning and attempted suicide, and that there is an increased risk of suicide in the LGB population. Numerous factors have been associated with suicide risk in this population, one of the main internalized homophobia and other mental health problems. By means of a literature review, to establish the possible relationship between internalized homophobia and ideation and attempted suicide in the LGB population, as well as to identify the mental health problems associated to suicide risk in sexually diverse communities. Articles in English and Spanish, mainly within the last five years, were reviewed. They included articles in peer reviewed journals, and databases, such as Google Scholar, Redalyc, Byreme, Ovid, Science Direct, Taylor and Francis, MEDLINE, Scopus, PsycINFO, and Ebsco. It was found in the available literature that internalized homophobia is associated with suicide ideation and attempts in adults. A state of science of the major mental health problems associated with suicide risk in young LGB people reported contradictory findings. While some studies showed an association between depression, anxiety and distress and suicidal ideation and attempts, in others, the data do not allow such a conclusion. The theoretical framework presents the most important conceptualizations of suicide risk and emphasizes the social type. It identifies issues of suicide prevention, protective factors that contribute towards this, as well as elements of psychotherapy for LGB consultants. It concludes and discusses the importance of studying the sexually diverse as regards determining factors

THE ACTIVE FUTURE OF THE AGED PEOPLE IN SPAIN

ANTONIO GUTIÉRREZ RESA
2015-11-01
Full Text Available In the following article we try to establish the foundations that support “the active future of the aged people in Spain”. We base our work on data from the National Institute of Statistics (INE, the Statistics Annuary of Spain, the Information System of the System for Autonomy and Dependency Caring (SISAAD and the Aged People Observatory-Institute of Aged People and Social Services (IMSERSO. Actually, one can notice that, if human beings are linked to production and utility, after 65–70 years of age, the possibilities of happiness can be accomplished now. We try to show that, with the number of people aged over 65 (8 million people in Spain increasing more than any other group and in acceptable health conditions, the context is more reasonable and facilitates an active future of the aged people. That is, the development of a process of optimization of health, participation and security opportunities, aiming at bettering the quality of life according as people age. We maintain that aging is not necessarily negative, the chronological age being a more and more unsatisfactory criterion. In the following pages we show the undeniable reality that we are going to live longer and probably in better conditions. Nevertheless, according to our data, it is convenient to distinguish from now on between people of 65 to 79 years and people of 80 and more. This stems, above all, from the domination of the dependency situations which go unsolved in Spain, despite the Law No. 6 of 2006. The article presents those services (IMSERSO which promote the active ageing: nurseries and clubs, vacations and thermal therapy, universities for aged people, accessibility programs and telealarms. Also presented are those services of familial solidarity promotion and maintaining: home help, residences, day nurseries and familial support services. The available data show the insufficiency of the aforementioned services in Spain. Therefore, we can say that the clearly pro

Research with and by people with learning disabilities.
Durell, Shirley
Many people with learning disabilities are frequently excluded from active involvement in research and, as a result, along with researchers, have questioned research processes. These discussions have influenced how research is undertaken by, and with, people who have learning disabilities. Learning disability research is now increasingly framed as inclusive. This article explores the development of inclusive learning disability research by tracing its background and influences, identifying key characteristics and highlighting some of the challenges in its application. It demonstrates how inclusive research can give people with learning disabilities a voice that will help to inform practice.

Indigenous older peoples' voices and experiences remain largely absent in the dominant models and critical scholarship on aging and late life. This article examines the relevance of the model of successful aging for Indigenous peoples in North America. This article presents the results of a review of the published conceptual literature on successful aging among Indigenous peoples. Our intent was to explore the current state of the field of successful aging among Indigenous peoples and suggest dimensions that may be more reflective of Indigenous voices and experiences that leads to a more inclusive model of successful aging. Based on our review, we suggest four dimensions that may broaden understandings of successful aging to be more inclusive of Indigenous older people: health and wellness, empowerment and resilience, engagement and behavior, and connectedness. Our review suggests that Indigenous peoples' voices and experiences are beginning to be included in academic literature on successful aging. However, we suggest that understandings of successful aging be broadened based on our summative findings and a process of community involvement. Such processes can lead to the development of models that are more inclusive to a wide range of older people, including Indigenous older peoples. © The Author 2016.

Evidence Map of Prevention and Treatment Interventions for Depression in Young People
Directory of Open Access Journals (Sweden)
Patrick Callahan
2012-01-01
Full Text Available Introduction. Depression in adolescents and young people is associated with reduced social, occupational, and interpersonal functioning, increases in suicide and self-harm behaviours, and problematic substance use. Age-appropriate, evidence-based treatments are required to provide optimal care. Methods. “Evidence mapping” methodology was used to quantify the nature and distribution of the extant high-quality research into the prevention and treatment of depression in young people across psychological, medical, and other treatment domains. Results. Prevention research is dominated by cognitive-behavioral- (CBT- based interventions. Treatment studies predominantly consist of CBT and SSRI medication trials, with few trials of other psychological interventions or complementary/alternative treatments. Quality studies on relapse prevention and treatment for persistent depression are distinctly lacking. Conclusions. This map demonstrates opportunities for future research to address the numerous evidence gaps for interventions to prevent or treat depression in young people, which are of interest to clinical researchers, policy makers, and funding bodies.

Full Text Available Organization and accounting should be based on accounting principles, which must ensure qualitative preparation of the financial statements. In this case an important role is played by the principle of domination of essence over form. Here is analyzed the main factors of its development and dissemination. Also it is determined the role of IFRS in the spreading of the principle of domination of essence over form in the world and its fixation on the level of normative regulation of accounting in certain countries, including Ukraine. It is defined theoretical preconditions for identifying and removing the existing obstacles in the application of the principle of domination of essence over form in the practice of management, which will ensure qualitative preparation of the financial statements. It is offered to use the principle of property rights theory, the theory of rent and the agency theory to solve the problem of disseverance between owner and manager.

[Dominating motivation in systemic memory mechanisms].
Sudakov, K V
2005-01-01
The materials provided in the article support the key role of dominating motivation in the systemic processes of fixation and opening of memory mechanisms. The activating mechanisms of dominating motivations in the systemic architectonics of behavioural acts provide the basis for development of a multicomponent acceptor apparatus of an action outcomes broadly represented in various analysing brain sections. As result of enhancement of action outcomes on acceptors structures, molecular behaviour engrammes form within the functional systems. It is these molecular engrammes that are opened by dominating motivations in the same spatial-temporal sequence in which training takes place, and determine deliberate actions of animals. It was demonstrated that dominating motivation opens genetic information with an approximating-exploratory reaction under strong activation of early genes expression, in particular, of c-fos gene protein. Inherent motivation reactions are not blocked by inhibitors of proteins synthesis, by cycloheximide, in particular. In the process of training animals, i.e., satisfaction of the demands which are the basis of dominating motivations, expression of early genes in reduced, while expression of late genes is initiated. In this case, blockators of protein synthesis begin to produce strong inhibiting impact on behaviour of animals.

The aim of this study was to determine the rate of change in falls risk and balance and mobility performance in people with Alzheimer disease (AD) compared with those of healthy older people over a 1-yr period. A 1-yr follow-up study of change in levels of falls risk, balance, and mobility performance in 15 community-dwelling older people with mild to moderate AD and 15 healthy age-matched older people was conducted. Each participant completed a comprehensive assessment of balance and mobility, falls and falls risk, and level of physical activity at baseline and 1 yr later. The rate of increase in the number of falls and risk of falling was greater in people with AD. The rate of deterioration on a number of balance and mobility measures was also significantly greater in people with AD compared with the healthy older people. People with mild to moderate AD have an increased rate of decline in falls risk, balance, and mobility over a 12-mo period compared with age-matched healthy older people. Given this increased rate of decline, intermittent review of falls, balance and mobility, and interventions to address identified contributory risk factors should be considered by health practitioners.

To report on the views of people with dementia who live in care homes and their family carers on aspects of design that are important to them, and discuss these in relation to developing physical care environments that respond to the wishes of people with dementia and their family carers. Six focus groups were held: two in Northern Ireland and four in Scotland. A total of 40 people participated in the focus groups. Twenty nine people were with dementia (24 female and five male), and 11 were family carers (10 female and one male). Carers discussed the features of a building they took into account when selecting a care home, and discussed this in relation to 'bricks and mortar versus people'. Key themes reported by people with dementia and their family carers included how the space in the environment is used, for example, what happens in the building and the presence or absence of certain design features. Outside space and wayfinding aids were identified as positive features of the home, along with a general lack of concern about ensuite provision. The results demonstrate the complexity of building design as it must provide living space acceptable to people with dementia living there and family members who visit, as well as provide a workable environment for staff. The findings highlight areas that should be considered by care home teams involved in the build of a new home or the redevelopment of an existing care home.

Cerebral autosomal dominant arteriopathy with sub cortical infarcts and leucoencephalopathy (CASADIL) is a systemic hereditary, vascular disease that involves small arteries. Recurrent ischemia, pseudo bulbar paralysis and dementia are characteristic. Other manifestations include migraine and depression. We report an Argentine family with VI generations with evidence of disease in IV. MR examinations were performed on 21 family members (both symptomatic and asymptomatic). The main findings on MR on symptomatic and asymptomatic patients were small lesions with high signal on T2 localised in periventricular white matter, brain stem, basal ganglia and thalamus, and confluent patches on white matter although with high signal on T2 images, usually symmetric. In conclusion we can assess that diffuse myelin loss and small infarcts occurring in cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy well demonstrated with MR. In addition, some of the abnormalities in pre symptomatic patients can be identified on MR images. (author)

Hypothalamic digoxin, hemispheric chemical dominance and sarcoidosis.
Ravi Kumar, A; Kurup, Parameswara Achutha
2004-06-01
The isoprenoid pathway produces three key metabolites: endogenous digoxin (membrane sodium-potassium ATPase inhibitor, immunomodulator and regulator of neurotransmitter/amino acid transport), dolichol (regulates N-glycosylation of proteins) and ubiquinone (free radical scavenger). The role of the isoprenoid pathway in the pathogenesis of sarcoidosis in relation to hemispheric dominance was studied. The isoprenoid pathway-related cascade was assessed in patients with systemic sarcoidosis with pulmonary involvement. The pathway was also assessed in patients with right hemispheric, left hemispheric and bihemispheric dominance for comparison to find out the role of hemispheric dominance in the pathogenesis of sarcoidosis. In patients with sarcoidosis there was elevated digoxin synthesis, increased dolichol and glycoconjugate levels and low ubiquinone and elevated free radical levels. There was also an increase in tryptophan catabolites and a reduction in tyrosine catabolites. There was an increase in the cholesterol:phospholipid ratio and a reduction in the glycoconjugate level of red blood cell (RBC) membrane in this group of patients. The same biochemical patterns were obtained in individuals with right hemispheric dominance. In individuals with left hemispheric dominance the patterns were reversed. Endogenous digoxin, by activating the calcineurin signal transduction pathway of T cells, can contribute to immune activation in sarcoidosis. An altered glycoconjugate metabolism can lead to the generation of endogenous self-glycoprotein antigens in the lung as well as other tissues. Increased free radical generation can also lead to immune activation. The role of a dysfunctional isoprenoid pathway and endogenous digoxin in the pathogenesis of sarcoidosis in relation to right hemispheric chemical dominance is discussed. All the patients with sarcoidosis were right-handed/left hemispheric dominant according to the dichotic listening test, but their biochemical patterns

Hypothalamic digoxin, hemispheric chemical dominance, and creativity.
Kurup, Ravi Kumar; Kurup, Parameswara Achutha
2003-04-01
The human hypothalamus produces an endogenous membrane Na(+)-K+ ATPase inhibitor, digoxin, which regulates neuronal transmission. The digoxin status and neurotransmitter patterns were studied in creative and non-creative individuals, as well as in individuals with differing hemispheric dominance, in order to find out the role of cerebral dominance in this respect. The activity of HMG CoA reductase and serum levels of digoxin, magnesium, tryptophan catabolites, and tyrosine catabolites were measured in creative/non-creative individuals, and in individuals with differing hemispheric dominance. In creative individuals there was increased digoxin synthesis, decreased membrane Na(+)-K+ ATPase activity, increased tryptophan catabolites (serotonin, quinolinic acid, and nicotine), and decreased tyrosine catabolites (dopamine, noradrenaline, and morphine). The pattern in creative individuals correlated with right hemispheric dominance. In non-creative individuals there was decreased digoxin synthesis, increased membrane Na(+)-K+ ATPase activity, decreased tryptophan catabolites (serotonin, quinolinic acid, and nicotine), and increased tyrosine catabolites (dopamine, noradrenaline, and morphine). This pattern in non-creative individuals correlated with that obtained in left hemispheric chemical dominance. Hemispheric chemical dominance and hypothalamic digoxin could regulate the predisposition to creative tendency.

Hypothalamic digoxin, hemispheric chemical dominance, and spirituality.
Kurup, Ravi Kumar; Kurup, Parameswara Achutha
2003-03-01
The isoprenoid pathway was assessed in atheistic and spiritually inclined individuals. The pathway was also assessed in individuals with differing hemispheric dominance to assess whether hemispheric dominance has a correlation with spiritual and atheistic tendency. HMG CoA reductase activity, serum digoxin, RBC membrane Na(+)-K+ ATPase activity, serum magnesium, and tyrosine/tryptophan catabolic patterns were assessed in spiritual/atheistic individuals and in those differing hemispheric dominance. In spiritually-inclined individuals, there was increased digoxin synthesis, decreased membrane Na(+)-K+ ATPase activity, increased tryptophan catabolites (serotonin, quinolinic acid, and nicotine), and decreased tyrosine catabolites (dopamine, noradrenaline, and morphine). The pattern in spiritually-inclined individuals correlated with right hemispheric chemical dominance. In atheistic individuals there was decreased digoxin synthesis, increased membrane Na(+)-K+ ATPase activity, decreased tryptophan catabolities (serotonin, quinolinic acid, and nicotine), and increased tyrosine catabolites (dopamine, noradrenaline, and morphine). This pattern in atheistic individuals correlated with that obtained in left hemispheric chemical dominance. Hemispheric chemical dominance and hypothalamic digoxin could regulate the predisposition to spirituality or atheism.

A quantitative analysis of secondary RNA structure using domination based parameters on trees
Directory of Open Access Journals (Sweden)

2006-03-01
Full Text Available Abstract Background It has become increasingly apparent that a comprehensive database of RNA motifs is essential in order to achieve new goals in genomic and proteomic research. Secondary RNA structures have frequently been represented by various modeling methods as graph-theoretic trees. Using graph theory as a modeling tool allows the vast resources of graphical invariants to be utilized to numerically identify secondary RNA motifs. The domination number of a graph is a graphical invariant that is sensitive to even a slight change in the structure of a tree. The invariants selected in this study are variations of the domination number of a graph. These graphical invariants are partitioned into two classes, and we define two parameters based on each of these classes. These parameters are calculated for all small order trees and a statistical analysis of the resulting data is conducted to determine if the values of these parameters can be utilized to identify which trees of orders seven and eight are RNA-like in structure. Results The statistical analysis shows that the domination based parameters correctly distinguish between the trees that represent native structures and those that are not likely candidates to represent RNA. Some of the trees previously identified as candidate structures are found to be "very" RNA like, while others are not, thereby refining the space of structures likely to be found as representing secondary RNA structure. Conclusion Search algorithms are available that mine nucleotide sequence databases. However, the number of motifs identified can be quite large, making a further search for similar motif computationally difficult. Much of the work in the bioinformatics arena is toward the development of better algorithms to address the computational problem. This work, on the other hand, uses mathematical descriptors to more clearly characterize the RNA motifs and thereby reduce the corresponding search space. These

The central goal of presurgical language mapping is to identify brain regions that subserve cortical language function to minimize postsurgical language deficits. Presurgical language mapping in patients with epilepsy presents a key challenge because of the atypical pattern of hemispheric language dominance found in this population, with higher incidences of bilateral and right-biased language dominance than typical. In this prospective study, we combine magnetoencephalography with a panel of tasks designed to separately assess receptive and expressive function to provide a sensitive measure of language function in 15 candidates for resective surgery. We report the following: 4 of 15 patients (27%) showed left hemisphere dominance across all tasks, 4 of 15 patients (27%) showed right hemisphere dominance across all tasks, and 7 of 15 (46%) showed discordant language dominance, with right-dominant receptive and left-dominant expressive language. All patients with discordant language dominance showed this right-receptive and left-expressive pattern. Results provide further evidence supporting the importance of using a panel of tasks to assess separable aspects of language function. The clinical relevance of the findings is discussed, especially about current clinical operative measures for assessing language dominance, which use single hemisphere procedure (intracarotid amobarbital procedure and awake intraoperative stimulation) for determining language laterality.

AR4VI: AR as an Accessibility Tool for People with Visual Impairments.
Coughlan, James M; Miele, Joshua
2017-10-01
Although AR technology has been largely dominated by visual media, a number of AR tools using both visual and auditory feedback have been developed specifically to assist people with low vision or blindness - an application domain that we term Augmented Reality for Visual Impairment (AR4VI). We describe two AR4VI tools developed at Smith-Kettlewell, as well as a number of pre-existing examples. We emphasize that AR4VI is a powerful tool with the potential to remove or significantly reduce a range of accessibility barriers. Rather than being restricted to use by people with visual impairments, AR4VI is a compelling universal design approach offering benefits for mainstream applications as well.

Genes and Mutations Causing Autosomal Dominant Retinitis Pigmentosa
Daiger, Stephen P.; Bowne, Sara J.; Sullivan, Lori S.
2015-01-01
Retinitis pigmentosa (RP) has a prevalence of approximately one in 4000; 25%–30% of these cases are autosomal dominant retinitis pigmentosa (adRP). Like other forms of inherited retinal disease, adRP is exceptionally heterogeneous. Mutations in more than 25 genes are known to cause adRP, more than 1000 mutations have been reported in these genes, clinical findings are highly variable, and there is considerable overlap with other types of inherited disease. Currently, it is possible to detect disease-causing mutations in 50%–75% of adRP families in select populations. Genetic diagnosis of adRP has advantages over other forms of RP because segregation of disease in families is a useful tool for identifying and confirming potentially pathogenic variants, but there are disadvantages too. In addition to identifying the cause of disease in the remaining 25% of adRP families, a central challenge is reconciling clinical diagnosis, family history, and molecular findings in patients and families.

Social marketing targeting Indigenous peoples: a systematic review.
Kubacki, Krzysztof; Szablewska, Natalia
2017-09-07
Social marketing is a discipline focused on the application of marketing principles to induce socially desirable behaviour change. As social marketing remains one of the main behaviour change approaches pursued by governments and international organisations, it is important to consider its use in relation to vulnerable groups that are particularly exposed to discriminatory practices, marginalisation, exclusion and destitution. The aim of this systematic review is to identify the extent to which Andreasen's (2002) six social marketing benchmark criteria were reported in social marketing interventions targeting Indigenous peoples. A total of 20 articles covering 13 social marketing interventions were identified for review. Although none of the interventions gave evidence that they addressed all six of the benchmark criteria, they appear to have been effective in challenging some of the issues faced by Indigenous peoples. However, the criteria of segmentation, exchange and competition remain underused in the identified interventions. Social marketing interventions targeting Indigenous peoples tend to rely on television and radio advertising, showing potential for more use of product, place and price to influence, facilitate and maintain socially desirable behaviour change. © The Author 2017.

Hereditary spastic paraplegias (HSP) are genetically exceedingly heterogeneous. To date, 37 genetic loci for HSP have been described (SPG1-41), among them 16 loci for autosomal dominant disease. Notwithstanding, further genetic heterogeneity is to be expected in HSP, as various HSP families do not link to any of the known HSP loci. In this study, we aimed to map the disease locus in a German family segregating autosomal dominant complicated HSP. A genome-wide linkage analysis was performed using the GeneChip Mapping 10Kv2.0 Xba Array containing 10,204 SNP markers. Suggestive loci were further analyzed by mapping of microsatellite markers. One locus on chromosome 12q23-24, termed SPG36, was confirmed by high density microsatellite fine mapping with a significant LOD score of 3.2. SPG36 is flanked by markers D12S318 and D12S79. Linkage to SPG36 was excluded in >20 additional autosomal dominant HSP families. Candidate genes were selected and sequenced. No disease-causing mutations were identified in the coding regions of ATXN2, HSPB8, IFT81, Myo1H, UBE3B, and VPS29. SPG36 is complicated by a sensory and motor neuropathy; it is therefore the eighth autosomal dominant subtype of complicated HSP. We report mapping of a new locus for autosomal dominant hereditary spastic paraplegia (HSP) (SPG36) on chromosome 12q23-24 in a German family with autosomal dominant HSP complicated by peripheral neuropathy.

Full Text Available The aim of this study was to determine the functional relationship between dominant and non-dominant hand in the strength endurance motor task - hand grip, in the referent population of healthy and young persons. For the purpose of the research we have implemented the method of isometric dynamometry and standardized hand grip test. The study included 48 participants, 23 of them being of female and 25 of male gender. The analysis of variance (ANOVA was used to determine the difference between the sets of variables in the function of gender and functional dimorphism, while the Bonferroni criterion was applied to determine the differences between pairs of individual variables. The difference between the maximum hand grip of dominant and non-dominant hand in female participants amounted to 9.28%, and in male ones 7.39% in favor of the dominant hand. There is no statistically significant difference between nondominant and dominant hand regarding the force endurance time aspect at 30%, 50% and 80% out of the maximum hand grip level, as well as at the absolute and relative force impulse indicators as an endurance measure. The value of gender dimorphism in relation to the absolute indicators of force momentum at 30%, 50% and 80% out of the maximum hand grip level in female participants is 0.9714, 0.9145, 0.9301, and in male participants 0.9515, 0.8264 and 0.8606. The force momentum indicators value at 30%, 50% and 80% out of the maximum hand grip level in female participants is ImpF30%=21167.58±6923.67 Ns, ImpF50%=10846.94±3800.56 Ns and ImpF80%=5438.46±1993.12 Ns, and in male participants ImpF30%=17734.03±6881.92 Ns, ImpF50%=13903.61±3437.76 Ns and ImpF80%=5117.53±1894.78 Ns. The obtained results can be used as the criteria for further research in special education and rehabilitation, medical and professional rehabilitation.

Employment of people with disabilities: Implications for HR management practices
Directory of Open Access Journals (Sweden)
P. Gida
2007-12-01
Full Text Available Purpose: The purpose of this paper is to, firstly, present the findings of an empirical study in which the human resource management practices associated with the employment of people with disabilities were investigated. The human resource management challenges related to employment of people with disabilities were also identified in the empirical study and are presented in this paper. A further purpose of this paper is to propose a number of recommendations focused on human resource management practices and principles aimed at assisting managers and human resource management specialists in their endeavours to effectively deal with the employment of people with disabilities. Design/Methodology/Approach: This paper is based on an empirical study in which interviews were conducted with respondents from 19 different organisations identified in the Financial Mail's 'Top 100 Organisations in South Africa' list. Findings: The findings from the empirical study suggest that very few organisations are dealing with the employment of people with disabilities as a priority in their equity strategies. Where attention is being given to this issue, respondents seem to either address it as a legal compliance issue or a social responsibility 'project'. Furthermore, very little has been done to review current human resource management practices to determine whether they are discriminatory towards people with disabilities. Based on the insights gained from these findings and in line with best practice principles identified in the relevant literature, a number of recommendations focusing on human resource management practices and principles in relation to the employment of people with disabilities are proposed. Implications: This paper provides a number of practical steps to consider as part of an organisation's response to equity strategies related to the employment of people with disabilities.

Understandings of depression: an interview study of Yoruba, Bangladeshi and White British people.
Lavender, Hilary; Khondoker, Abul Hussain; Jones, Roger
2006-12-01
Depression remains a major public health problem, but little is known about the views and understandings of depression held by many ethnic groups. Aim. To explore views and understandings of depression in three ethnic groups-Yoruba, Sylheti-speaking Bangladeshi and White British-living in South London. Qualitative, semi-structured interviews, using vignettes describing depressed individuals. General practice and the community in Southwark, South London, UK. Participants. 20 Yoruba, 20 Bangladeshi and 20 White British people, recruited from primary care. Interviews (in English for Yoruba and White British, in Sylheti for the Bangladeshi participants) were recorded and transcribed. Atlas ti software was used to organize the data. Views on the causes and cures for depression were diverse. A diagnosis of depression can have adverse social consequences in all groups. Magic had a role in both causation and cure in the Yoruba and to a lesser extent in the Bangladeshi groups. Religion was important for many people in all groups. Family factors were dominant in the Bangladeshi participants, whilst the White British often identified more 'psychological' causes of depression. Coping methods and health-seeking behaviours included religion, family, friends and neighbours, and becoming more active. Formal psychiatric interventions and taking antidepressants were not priorities. Cultural models of depression, including its causes and treatment, are diverse, and are different among cultural groups. This study raises questions about the value of Western approaches to mild and moderate depression in these groups of patients.

Identifying the key concerns of Irish persons with intellectual disability.
García Iriarte, Edurne; O'Brien, Patricia; McConkey, Roy; Wolfe, Marie; O'Doherty, Siobhain
2014-11-01
Internationally, people with intellectual disability are socially marginalized, and their rights under the United Nations Convention for the Rights of Persons with Disabilities (CRPD) are often ignored. This paper aims to define the key concerns of adults with an intellectual disability in relation to their participation in society using an inclusive research strategy for both data gathering and data analysis. A national study involving 23 focus groups and 168 persons was conducted on the island of Ireland with people with intellectual disability as co-facilitators. A thematic content analysis was undertaken of the verbatim transcripts initially by university co-researchers, and 19 themes were identified. Co-researchers with intellectual disability joined in identifying the eight core themes. These were as follows: living options, employment, relationships, citizenship, leisure time, money management, self-advocacy, and communication. The concerns are discussed within the framework of the CRPD, and implications for transforming service policy are drawn. Why we did the research In many countries, people with intellectual disability have difficulties doing things other people without disabilities do, for example to study, to get a job or to live independently. They also find that their rights are not respected under the Convention on the Rights of Persons with Disabilities (the Convention). We did this study to Learn what are the main issues for adults with intellectual disability in Ireland. Do research with people with intellectual disability. How we did the research People with intellectual disability and their supporters worked with university researchers to plan and do the research. We met with people in groups and 168 people told us about things important to them. What we found out We found that there were very important things that people talked about in the groups. We chose the most important: living options, employment, relationships, rights, leisure, money

Factors influencing cancer treatment decision-making by indigenous peoples: a systematic review.
Tranberg, Rona; Alexander, Susan; Hatcher, Deborah; Mackey, Sandra; Shahid, Shaouli; Holden, Lynda; Kwok, Cannas
2016-02-01
We aim to systematically review studies that identify factors influencing cancer treatment decision-making among indigenous peoples. Following the outline suggested by the Preferred Reporting Items for Systematic Review and Meta-analysis, a rigorous systematic review and meta-synthesis were conducted of factors that influence cancer treatment decision-making by indigenous peoples. A total of 733 articles were retrieved from eight databases and a manual search. After screening the titles and abstracts, the full text of 26 articles were critically appraised, resulting in five articles that met inclusion criteria for the review. Because the five articles to be reviewed were qualitative studies, the Critical Appraisal Skills Program toolkit was used to evaluate the methodological quality. A thematic synthesis was employed to identify common themes across the studies. Multiple socio-economic and cultural factors were identified that all had the potential to influence cancer treatment decision-making by indigenous people. These factors were distilled into four themes: spiritual beliefs, cultural influences, communication and existing healthcare systems and structures. Although existing research identified multiple factors influencing decision-making, this review identified that quality studies in this domain are scarce. There is scope for further investigation, both into decision-making factors and into the subsequent design of culturally appropriate programmes and services that meet the needs of indigenous peoples.

Highly dominating, highly authoritarian personalities.
Altemeyer, Bob
2004-08-01
The author considered the small part of the population whose members score highly on both the Social Dominance Orientation scale and the Right-Wing Authoritarianism scale. Studies of these High SDO-High RWAs, culled from samples of nearly 4000 Canadian university students and over 2600 of their parents and reported in the present article, reveal that these dominating authoritarians are among the most prejudiced persons in society. Furthermore, they seem to combine the worst elements of each kind of personality, being power-hungry, unsupportive of equality, manipulative, and amoral, as social dominators are in general, while also being religiously ethnocentric and dogmatic, as right-wing authoritarians tend to be. The author suggested that, although they are small in number, such persons can have considerable impact on society because they are well-positioned to become the leaders of prejudiced right-wing political movements.

2009-03-01
Full Text Available Abstract Background Plantar hyperkeratotic lesions are common in older people and are associated with pain, mobility impairment and functional limitations. However, little has been documented in relation to the frequency or distribution of these lesions. The aim of this study was to document the occurrence of plantar hyperkeratotic lesions and the patterns in which they occur in a random sample of older people. Methods A medical history questionnaire was administered to a random sample of 301 people living independently in the community (117 men, 184 women aged between 70 and 95 years (mean 77.2, SD 4.9, who also underwent a clinical assessment of foot problems, including the documentation of plantar lesion locations, toe deformities and the presence and severity of hallux valgus. Results Of the 301 participants, 180 (60% had at least one plantar hyperkeratotic lesion. Those with plantar lesions were more likely to be female (χ2 = 18.75, p 2 = 6.15, p vs 36.3 ± 8.4°; t = 2.68, df = 286, p vs 4.8 ± 1.3 hours, t = -2.46, df = 299, p = 0.01. No associations were found between the presence of plantar lesions and body mass index, obesity, foot posture, dominant foot or forefoot pain. A total of 53 different lesions patterns were observed, with the most common lesion pattern being "roll-off" hyperkeratosis on the medial aspect of the 1st metatarsophalangeal joint (MPJ, accounting for 12% of all lesion patterns. "Roll-off" lesions under the 1st MPJ and interphalangeal joint were significantly associated with moderate to severe hallux valgus (p p Conclusion Plantar hyperkeratotic lesions affect 60% of older people and are associated with female gender, hallux valgus, toe deformity, increased ankle flexibility and time spent on feet, but are not associated with obesity, limb dominance, forefoot pain or foot posture. Although there are a wide range of lesion distribution patterns, most can be classified into medial, central or lateral groups. Further

European dominant position and american monopolization: a unifying approach from basic game theory
Directory of Open Access Journals (Sweden)
Pier Luigi Parcu
2006-06-01
Full Text Available In this paper we explore the meaning of some fundamental legal definitions of Europeanand American antitrust using basic concepts of game theory. Important definitions in EU law likedominant position of a firm, abuse of such a dominant position, special responsibility of thedominant firm, or in US law like monopoly or monopolization offence, acquire more precisemeaning and operational content. Moreover they look closer than usually contended.In a competition game, in which there is a truly monopolistic/dominant firm (MDF andcompetition law is respected, we state in a formal theorem that an MDF has a dominant strategy, soits choices should never be a source of ex post regret. Other players of the game, understanding andanticipating the realization of this dominant strategy, will optimize their behaviour taking it intoaccount and thus be more able to select a best solution among all possible outcomes.In this context which kind of behaviours can an MDF adopt to defend its market shares andeconomic position? Following the US Supreme Court and EU Court of Justice an MDF mustcompete using normal methods of competition, superior product or business acumen, therefore weargue that market power, whatever its origin, can be defended only through competition on themerit. This definition has practical consequences: unpredictable behaviours and actions that anormal firm would not adopt might be identified as illegal abuses of dominant position ormonopolization offences, also this idea is formalized in a theorem.

Methods dialectic approach to the cognition of social phenomena allowing to analyze them in their historical development and functioning in the context of the integrity of subjective and objective factors this determines the choice of the research methods systemicstructural formallegal and comparative. Results The first part of this chapter will explain the way in which people in societies different from our own were subject to other motivations in situations where selfinterest would tend to dominate in our society. The reasoning is based on three examples one drawn from the history of Ancient Rome one from the High Middle Ages of the European society and one from a contemporary nonWestern culture. The second part of the chapter analyzes the reason why material selfinterest maximizing became a dominant motivation in the modern Western society. The works on historical sociology attribute this development to Calvinism but this hypothesis suffers from some serious defects. In the article we prove that the modern sensibility resulted from much longeracting trends specifically secularization urbanization and commercialization. The final section of the chapter explores the relationship between the Westrsquos prevailing norm of selfinterest maximization and the particular norms that have been discussed in microeconomic theory. It argues that some of these norms are internal to the prevailing one and are thus explicable in terms of material selfinterest but that others reflect additional norms in the general society that exist alongside and sometimes in competition with the prevailing norm of selfinterest maximization. The historicallybased view that selfinterest maximizing is a prevailing norm rather than a human universal allows these other norms to be acknowledged in a plausible and realistic manner rather than being explained away by a

SOME CONSIDERATIONS ON ABUSE OF DOMINANT POSITION
Directory of Open Access Journals (Sweden)
Ovidiu Maican
2007-12-01
Full Text Available Article 82 (formerly 86 EC contains four essential elements (an undertaking, a dominant position, an abuse of that position and the abuse must affect trade between member states. The term undertakings is subject to the same broad interpretation as that applied to article 81 (formerly 85 EC and covers the same activities, both public and private.The Community interest must be also taken into account. Although it is not clear precisely what this element of article 86 requires, it will clearly curtail the scope of the exception provided under this article. Although abusive behavior of undertakings in a dominant position is prohibited, it must be recalled that merely being in a strong position is not a problem in itself. It is necessary for major players in a market to be aware of their position because practices which would not fall foul of article 82 (formerly 86 EC, where an undertaking is not dominant, will do so where dominance is established. A refusal to deal by a non-dominant undertaking would not be an abuse within article 82 (formerly 86 EC, but it will be so where the undertaking is dominant.

Increasing levels of carbon dioxide in the atmosphere put shallow, warm-water coral reef ecosystems, and the people who depend upon them at risk from two key global environmental stresses: 1) elevated sea surface temperature (that can cause coral bleaching and related mortality), and 2) ocean acidification. These global stressors: cannot be avoided by local management, compound local stressors, and hasten the loss of ecosystem services. Impacts to people will be most grave where a) human dependence on coral reef ecosystems is high, b) sea surface temperature reaches critical levels soonest, and c) ocean acidification levels are most severe. Where these elements align, swift action will be needed to protect people's lives and livelihoods, but such action must be informed by data and science. Designing policies to offset potential harm to coral reef ecosystems and people requires a better understanding of where CO2-related global environmental stresses could cause the most severe impacts. Mapping indicators has been proposed as a way of combining natural and social science data to identify policy actions even when the needed science is relatively nascent. To identify where people are at risk and where more science is needed, we map indicators of biological, physical and social science factors to understand how human dependence on coral reef ecosystems will be affected by globally-driven threats to corals expected in a high-CO2 world. Western Mexico, Micronesia, Indonesia and parts of Australia have high human dependence and will likely face severe combined threats. As a region, Southeast Asia is particularly at risk. Many of the countries most dependent upon coral reef ecosystems are places for which we have the least robust data on ocean acidification. These areas require new data and interdisciplinary scientific research to help coral reef-dependent human communities better prepare for a high CO2 world.

Managing young people with self-harming or suicidal behaviour.
Fisher, Gemma
2016-02-01
This literature review aimed to determine the risk factors being used to identify children and young people who are at increased risk of engaging in self-harm and suicidal behaviour, so that optimal care can be provided for this patient group in children's medical ward settings. The two main themes that emerged were mental and neurodevelopmental disorders, and external factors. Management strategies to aid healthcare professionals in caring for this patient group were also identified. The review concludes by highlighting the need to provide healthcare professionals with continuing education about the mental health problems of children and young people, including risk factors and management strategies.

Domination, self-determination and circular organizing
Romme, A.G.L.
2002-01-01
The emergence of self-organizing forms of control, based on the idea of self-determination, have challenged traditional forms of control based on the concept of domination. As such, self-determination has been put forward as an alternative rather than as a complement to domination. This paper

Pressure transmitter surveillance: the dominant real pole case
International Nuclear Information System (INIS)
Blazquez, J.; Ballestrin, J.
1995-01-01
There are about 500 pressure transmitters in a nuclear power plant. Due to Safety requirements, some of them must be specially surveilled. Sensor response time to a pressure ramp is the usual quantity to be measured. Response time, τ r , reflects the dynamics of the sensor and the sensing line. A real pole is due to the inner sensor structure, but the complex pole stands for the sensing line too. The real pole usually is the dominant in most sensors. On line monitoring noise analysis regards simultaneously both, the sensor and the sensing line, but the noise signal contains not only the sensor poles, but many others coming from the plant, so must be conditioned previously and the determination of τ r is not free of systematic errors. That is the price to be paid for non disturbing the plant. When the real pole is dominant, the sensing line contribution is negligible, so the on line noise monitoring methods are supported by the laboratory experiments and the real pole border in the PSD is properly identified. The mean square frequency results proportional to τ r -1 , so manual techniques are designed for response time surveillance made by non noise plant's maintenance technicians. (author)

Urban transitions: on urban resilience and human-dominated ecosystems.
Ernstson, Henrik; van der Leeuw, Sander E; Redman, Charles L; Meffert, Douglas J; Davis, George; Alfsen, Christine; Elmqvist, Thomas
2010-12-01
Urbanization is a global multidimensional process paired with increasing uncertainty due to climate change, migration of people, and changes in the capacity to sustain ecosystem services. This article lays a foundation for discussing transitions in urban governance, which enable cities to navigate change, build capacity to withstand shocks, and use experimentation and innovation in face of uncertainty. Using the three concrete case cities--New Orleans, Cape Town, and Phoenix--the article analyzes thresholds and cross-scale interactions, and expands the scale at which urban resilience has been discussed by integrating the idea from geography that cities form part of "system of cities" (i.e., they cannot be seen as single entities). Based on this, the article argues that urban governance need to harness social networks of urban innovation to sustain ecosystem services, while nurturing discourses that situate the city as part of regional ecosystems. The article broadens the discussion on urban resilience while challenging resilience theory when addressing human-dominated ecosystems. Practical examples of harnessing urban innovation are presented, paired with an agenda for research and policy.

Indigenous Peoples, especially women and children, are affected disproportionately by malnutrition and diet-related health problems. Addressing this requires an investigation of the structural conditions that underlie unequal access to resources and loss of traditional lifestyles and necessitates inclusive approaches that shed light onto these issues and provide strategies to leverage change. Indigenous Peoples' food systems are inextricably connected to land, which in turn is interwoven with issues of self-determination, livelihoods, health, cultural and spiritual heritage, and gender. Ongoing loss of land and the dominant agri-food model further threaten Indigenous Peoples' food systems. Continuing gender-based discrimination undermines the self-determination and rights of women and negatively impacts their health, nutritional status, and overall well-being, as well as the well-being of households and communities. We suggest that feminist political ecology and modern matriarchal studies provide holistic interlinking frameworks for investigating underlying issues of power and inequality. We further argue that a focus on the principles of respect, responsibility, and relationships, and an openness to different worldviews, can facilitate a bridging of Indigenous and Western approaches in research and community action conducted in partnership with Indigenous Peoples. This can contribute to creating new ways of knowing regarding Indigenous Peoples' food systems, equally valuing both knowledge systems. Indigenous Peoples' rights, right to food, and food sovereignty are frames that, despite some tensions, have the common goal of self-determination. Through their ability to inform, empower, and mobilize, they provide tools for social movements and communities to challenge existing structural inequalities and leverage social change. © 2018 John Wiley & Sons Ltd.

Purpose Mutational load of susceptibility variants has not been studied on a genomic scale in a clinical population, nor has the potential to identify these mutations as incidental findings during clinical testing been systematically ascertained. Methods Array comparative genomic hybridization, a method for genome-wide detection of DNA copy-number variants, was performed clinically on DNA from 9,005 individuals. Copy-number variants encompassing or disrupting single genes were identified and analyzed for their potential to confer predisposition to dominant, adult-onset disease. Multigene copy-number variants affecting dominant, adult-onset cancer syndrome genes were also assessed. Results In our cohort, 83 single-gene copy-number variants affected 40 unique genes associated with dominant, adult-onset disorders and unrelated to the patients’ referring diagnoses (i.e., incidental) were found. Fourteen of these copy-number variants are likely disease-predisposing, 25 are likely benign, and 44 are of unknown clinical consequence. When incidental copy-number variants spanning up to 20 genes were considered, 27 copy-number variants affected 17 unique genes associated with dominant, adult-onset cancer predisposition. Conclusion Copy-number variants potentially conferring susceptibility to adult-onset disease can be identified as incidental findings during routine genome-wide testing. Some of these mutations may be medically actionable, enabling disease surveillance or prevention; however, most incidentally observed single-gene copy-number variants are currently of unclear significance to the patient.

To examine the effects of women's subjective definitions of wife abuse and of their general attitudes to acceptance of male dominance on the occurrence of domestic violence. A case-control survey was conducted in the public health center of Babol University of Medical Sciences from November 2002 to October 2003. The Abuse Assessment Screen Form was used to identify partner violence, and the Abuse Definition Form and Abuse Attitude Form were applied to measure how the women defined wife abuse and their attitudes to male dominance. Women with positive attitudes to male dominance had experienced more physical and emotional abuse than those with negative attitudes toward male dominance (p family income were important risk factors for domestic violence, the strongest predictor of physical abuse was a positive attitude to male dominance. A positive attitude of women to male dominance increases the acceptance and frequency of partner violence. This finding shows the need to raise the educational levels of women and raise their awareness of their rights. This could convert an attitude of male dominance to equality of men and women.

Young people's attitudes towards illicit drugs: A population-based study.
Friis, Karina; Østergaard, Jeanette; Reese, Sidsel; Lasgaard, Mathias
2017-12-01
Previous studies indicate that young people who have positive attitudes towards illicit drugs are more inclined to experiment with them. The first aim of our study was to identify the sociodemographic and risk behaviour characteristics of young people (16-24 years) with positive attitudes towards illicit drug use. The second aim was to identify the characteristics of young people with positive attitudes towards illicit drugs among those who had never tried drugs, those who had tried cannabis but no other illicit drugs, and those who regularly used cannabis and/or had tried other illicit drugs. The analysis was based on a population-based survey from 2013 ( N = 3812). Multiple logistic regression was used to analyse the association between sociodemographic and risk behaviour characteristics and positive attitudes towards illicit drugs. Young men had twice the odds of having positive attitudes towards illicit drug use compared with young women (AOR = 2.1). Also, young age, being single, being employed, smoking tobacco, practising unprotected sex, and experimental cannabis use were associated with positive attitudes towards illicit drug use. Finally, use of cannabis at least 10 times during the previous year and/or use of other illicit drugs had the strongest association with positive attitudes to illicit drug use (AOR = 6.0). Young people who have positive attitudes towards illicit drug use are characterized by a broad range of risky behaviours. These findings may help to identify young people at risk of initiating illicit drug use and thereby support the development and implementation of prevention programmes.

Transmasculine people assigned female sex at birth but who do not identify with this classification have traditionally received little consideration in the voice literature. Some voice researchers and clinicians suggest that transmasculine people do not need attention because testosterone treatment leads to a satisfactory masculinization of their voice organs and voices. Others, however, argue that transmasculine people are a heterogeneous group whose members might not share the same body type, gender identity or desire for medical approaches to gender transitioning. Therefore, testosterone-induced voice changes may not necessarily meet the needs and expectations of all transmasculine people. To evaluate the gender-related discursive and empirical data about transmasculine people's vocal situations to identify gaps in the current state of knowledge and to make suggestions for future voice research and clinical practice. A comprehensive review of peer-reviewed academic and clinical literature was conducted. Publications were identified by searching seven electronic databases and bibliographies of relevant articles. Thirty-one publications met inclusion criteria. Discourses and empirical data were analysed thematically. Potential problem areas that transmasculine people may experience were identified and the quality of evidence appraised. The extent and quality of voice research conducted with transmasculine people so far was found to be limited. There was mixed evidence to suggest that transmasculine people's vocal situations could be regarded as problematic. The diversity that characterizes the transmasculine population received little attention and the complexity of the factors that contribute to a successful or unsuccessful vocal communication of gender in this group appeared to be under-researched. While most transmasculine people treated with testosterone can expect a lowering of their pitch, it remains unclear whether the extent of the pitch change is enough

The purpose of this study is to describe recessive alleles in strictly dominant genes. Identifying recessive mutations in genes for which only dominant disease or risk alleles have been reported can expand our understanding of the medical relevance of these genes both phenotypically and mechanistically. The Saudi population is enriched for autozygosity, which enhances the homozygous occurrence of alleles, including pathogenic alleles in genes that have been associated only with a dominant inheritance pattern.Exome sequencing of patients from consanguineous families with likely recessive phenotypes was performed. In one family, the genotype of the deceased children was inferred from their parents due to lack of available samples.We describe the identification of 11 recessive variants (5 of which are reported here for the first time) in 11 genes for which only dominant disease or risk alleles have been reported. The observed phenotypes for these recessive variants were novel (e.g., FBN2-related myopathy and CSF1R-related brain malformation and osteopetrosis), typical (e.g., ACTG2-related visceral myopathy), or an apparently healthy state (e.g., PDE11A), consistent with the corresponding mouse knockout phenotypes.Our results show that, in the era of genomic sequencing and

An Observational Study of Suicide Death in Homeless and Precariously Housed People in Toronto.
Sinyor, Mark; Kozloff, Nicole; Reis, Catherine; Schaffer, Ayal
2017-07-01
Homelessness has been identified as an important risk factor for suicide death, but there is limited research characterising homeless people who die by suicide. The goal of this study is to identify personal, clinical, and suicide method-related factors that distinguish homeless and precariously housed people who die from suicide from those who are not homeless at the time of suicide. Coroner records were reviewed for all suicide deaths in Toronto from 1998 to 2012. Data abstracted included housing status as well as other demographics, clinical variables such as the presence of mental illness, and suicide method. Of 3319 suicide deaths, 60 (1.8%) were homeless and 230 (6.9%) were precariously housed. Homeless and precariously housed people were each younger than nonhomeless people ( P suicide note. Homeless people and precariously housed were more likely to have died by fall/jump than nonhomeless people (62%, 57%, and 29%, respectively). Homeless and precariously housed people are overrepresented among suicide deaths in a large urban center and differ demographically, clinically, and in their suicide method from nonhomeless people who die by suicide. Targeted suicide prevention strategies should aim to address factors specific to homeless people.

Services for people with communication disability in Fiji: barriers and drivers of change.
Hopf, Suzanne C; McLeod, Sharynne
2015-01-01
The World Health Organization's World report on disability calls upon all nations to 'remove the barriers which prevent [people with disabilities] from participating in their communities; getting a quality education, finding decent work, and having their voices heard' (p. 5). People with communication disability (PWCD), as a consequence of their atypical communication, may be more likely to be excluded from society, and denied their basic human rights, than other people with disability. Fiji, a multicultural and multilingual nation in the south-western Pacific Ocean, has limited services for PWCD. Service providers in Fiji include disability care workers, special education teachers, traditional healers, and a small number of visiting volunteer speech-language pathologists. This paper outlines the historical and current barriers to, and drivers of change for, service development for PWCD in Fiji. Five barriers to service development for PWCD in Fiji were identified. (1) A major structural barrier is the small population size to develop appropriate infrastructure including professional education programs. (2) Geographical barriers include the dispersed geography across 300 islands, low population density, the rural-urban divide, and risk of disaster from cyclones and flooding. (3) Linguistic diversity, while culturally important, can present a barrier to the provision of quality services that are available in the languages spoken by PWCD. (4) Cultural barriers include historical political instability, although Fiji has become more stable due to the recent democratic elections. The social climate affects development of services that are appropriate for different dominant cultural groups. (5) Financial barriers include low gross domestic product, low financial security and low human development index; however, the financial outlook for Fiji is steadily improving due to the change in political stability. Three levels of drivers of change were identified. Macro

Large rivers in continents have a characteristic of slow rise and fall in water levels during floods or the wet season due to a wide drainage basin. A gentle river gradient and large water discharge have relatively large tidal ranges at the river mouth, resulting in large backwater effects further upstream. The result of the Mekong River survey (386 riverbed sediments, river topography, CTD, and biofacies) shows that the distributary channels of the Mekong River delta in Vietnam are divided into two parts: the landward river-dominated tract (RDT) and seaward tide-dominated tract (TDT). The RDT is characterized by a highly variable and deepening trend in water depth and coarse-grained sediments with a fining trend downstream. The TDT is characterized by a shallowing trend in water depth with river-widening, smooth riverbeds, a straight shape, and heterolithic f- to vf-sand and mud alternation (tidal thythmite). The boundary of both tracts is sharply identified by sediment facies and river morphology. Sediment facies indicates that the dominant sedimentary process of bottom sediments is "bedload" in the RDT and "suspension" in the TDT. Daily tidal changes are observed through the year, while water-level changes during the flood/wet season are limited in the TDT. Saltwater intrusion is limited within the seaward part of the TDT alone ( 50 km), close to final bifurcation points. However, brackish-water biofacies is observed in the TDT mainly due to diluted brackish water and/or tolerance to the freshwater environment. These characteristics are also found in the Yangtze; the distance of the TDT/RDT boundary from the river mouth is ca. 100 km in the Mekong, and 200 km in the Yangtze. The preservation potential of sediments in a TDT is low in a progradational system, and high in abandoned channels. The early Holocene transgressive estuary system in the incised valley of the Yangtze formed during the Last Glacial Maximum was composed of 20 m-thick fine-grained heterolithic

Increasing participation of people with learning disabilities in bowel screening.
Gray, Jonathan
2018-03-08
Learning disability nurses have a key role in addressing the health inequalities experienced by people with learning disabilities. People with learning disabilities are less likely to participate in bowel screening than other sectors of the population, despite there being evidence of this population being at an increased risk of developing bowel cancer. There are a range of barriers at individual and systemic levels that impact on participation in bowel screening by people with learning disabilities. Actions to address these barriers have been identified in the literature and learning disability nurses are a key agent of change in enabling people with learning disabilities to participate in the national screening programmes.

EDAR mutation in autosomal dominant hypohidrotic ectodermal dysplasia in two Swedish families
Directory of Open Access Journals (Sweden)
Schmitt-Egenolf Marcus
2006-11-01
Full Text Available Abstract Background Hypohidrotic ectodermal dysplasia (HED is a genetic disorder characterized by defective development of teeth, hair, nails and eccrine sweat glands. Both autosomal dominant and autosomal recessive forms of HED have previously been linked to mutations in the ectodysplasin 1 anhidrotic receptor (EDAR protein that plays an important role during embryogenesis. Methods The coding DNA sequence of the EDAR gene was analyzed in two large Swedish three-generational families with autosomal dominant HED. Results A non-sense C to T mutation in exon 12 was identified in both families. This disease-specific mutation changes an arginine amino acid in position 358 of the EDAR protein into a stop codon (p.Arg358X, thereby truncating the protein. In addition to the causative mutation two polymorphisms, not associated with the HED disorder, were also found in the EDAR gene. Conclusion The finding of the p.Arg358X mutation in the Swedish families is the first corroboration of a previously described observation in an American family. Thus, our study strengthens the role of this particular mutation in the aetiology of autosomal dominant HED and confirms the importance of EDAR for the development of HED.

The morphological classification of heartbeats as dominant and non-dominant in ECG signals
International Nuclear Information System (INIS)
Chiarugi, Franco; Emmanouilidou, Dimitra; Tsamardinos, Ioannis
2010-01-01
Surface electrocardiography (ECG) is the art of analyzing the heart's electrical activity by applying electrodes to certain positions on the body and measuring potentials at the body surface resulting from this electrical activity. Usually, significant clinical information can be obtained from analysis of the dominant beat morphology. In this respect, identification of the dominant beats and their averaging can be very helpful, allowing clinicians to carry out the measurement of amplitudes and intervals on a beat much cleaner from noise than a generic beat selected from the entire ECG recording. In this paper a standard clustering algorithm for the morphological grouping of heartbeats has been analyzed based on K-means, different signal representations, distance metrics and validity indices. The algorithm has been tested on all the records of the MIT-BIH Arrhythmia Database (MIT-BIH AD) obtaining satisfying performances in terms of averaged dominant beat estimation, but the results have not been fully satisfactory in terms of sensitivity and specificity. In order to improve the clustering accuracy, an ad hoc algorithm based on a two-phase decision tree, which integrates additional specific knowledge related to the ECG domain, has been implemented. Similarity features extracted from every beat have been used in the decision trees for the identification of different morphological classes of ECG beats. The results, in terms of dominant beat discrimination, have been evaluated on all annotated beats of the MIT-BIH AD with sensitivity = 99.05%, specificity = 93.94%, positive predictive value = 99.32% and negative predictive value = 91.69%. Further tests have shown a very slight decrement of the performances on all detected beats of the same database using an already published QRS detector, demonstrating the validity of the algorithm in real unsupervised clustering situations where annotated beat positions are not available but beats are detected with a high

Urban Kampong is a spontaneous settlement growing in several big cities within developing countries including Indonesia. This settlement is developed by low-income people without any plan. Therefore there is no specific housing pattern in the settlement. The characteristics of the settlements is dominated by Javanese traditional roof typology and narrow path with minimal public open spaces. People's creativity in building their houses often uses second hand building materials that make their houses look specific. Besides, infrastructure facilities within Kampong Settlement are very poor. Because the poor living in Urban Kampong have to adjust their live with minimum infrastructure facilities available, they have to be creative in using all facilities available. Through the creativities of low-income people living in Urban Kampong the research will show how the inhabitants can be empowered by exploring inhabitant's creativities and consequently the environmental quality within Urban Kampong can be improved as well.

Fuzzy ranking based non-dominated sorting genetic algorithm-II for network overload alleviation
Directory of Open Access Journals (Sweden)
Pandiarajan K.
2014-09-01
Full Text Available This paper presents an effective method of network overload management in power systems. The three competing objectives 1 generation cost 2 transmission line overload and 3 real power loss are optimized to provide pareto-optimal solutions. A fuzzy ranking based non-dominated sorting genetic algorithm-II (NSGA-II is used to solve this complex nonlinear optimization problem. The minimization of competing objectives is done by generation rescheduling. Fuzzy ranking method is employed to extract the best compromise solution out of the available non-dominated solutions depending upon its highest rank. N-1 contingency analysis is carried out to identify the most severe lines and those lines are selected for outage. The effectiveness of the proposed approach is demonstrated for different contingency cases in IEEE 30 and IEEE 118 bus systems with smooth cost functions and their results are compared with other single objective evolutionary algorithms like Particle swarm optimization (PSO and Differential evolution (DE. Simulation results show the effectiveness of the proposed approach to generate well distributed pareto-optimal non-dominated solutions of multi-objective problem

Hypothalamic digoxin, hemispheric chemical dominance, and the tridosha theory.
Kurup, Ravi Kumar; Kurup, Parameswara Achutha
2003-05-01
Ayurveda, the traditional Indian System of Medicine, deals with the theory of the three tridosha states (both physical and psychological): Vata, Pitta, and Kapha. They are the three major human constitutional types that both depend on psychological and physical characteristics. The Pitta state is described as a critical, discriminative, and rational psychological state of mind, while the Kapha state is described as being dominant for emotional stimuli. The Vata state is an intermediate unstable shifting state. The Pitta types are of average height and built with well developed musculature. The Vata types are thin individuals with low body mass index. The Kapha types are short stocky individuals that tend toward obesity, and who are sedentary. The study assessed the biochemical differences between right hemispheric dominant, bihemispheric dominant, and left hemispheric dominant individuals, and then compared this with the patterns obtained in the Vata, Pitta, and Kapha states. The isoprenoid metabolites (digoxin, dolichol, and ubiquinone), glycoconjugate metabolism, free radical metabolism, and the RBC membrane composition were studied. The hemispheric chemical dominance in various systemic diseases and psychological states was also investigated. The results showed that right hemispheric chemically dominant/Kapha state had elevated digoxin levels, increased free radical production and reduced scavenging, increased tryptophan catabolites and reduced tyrosine catabolites, increased glycoconjugate levels and increased cholesterol: phospholipid ratio of RBC membranes. Left hemispheric chemically dominant/Pitta states had the opposite biochemical patterns. The patterns were normal or intermediate in the bihemispheric chemically dominant/Vata state. This pattern could be correlated with various systemic and neuropsychiatric diseases and personality traits. Right hemispheric chemical dominance/Kapha state represents a hyperdigoxinemic state with membrane sodium

Foam topology. Bending versus stretching dominated architectures
International Nuclear Information System (INIS)
Deshpande, V.; Ashby, M.; Fleck, N.
2000-01-01
Cellular solids can deform by either the bending or stretching of the cell walls. While most cellular solids are bending-dominated, those that are stretching-dominated are much more weight-efficient for structural applications. In this study we have investigated the topological criteria that dictate the deformation mechanism of a cellular solid by analysing the rigidity (or otherwise) of pin-jointed frameworks comprising inextensional struts. We show that the minimum node connectivity for a special class of lattice structured materials to be stretching-dominated is 6 for 2D foams and 12 for 3D foams. Similarly, sandwich plates comprising of truss cores faced with planar trusses require a minimum node connectivity of 9 to undergo stretching-dominated deformation for all loading states. (author)

Hypothalamic digoxin, hemispheric chemical dominance, and sleep.
Kurup, Ravi Kumar; Kurup, Parameswara Achutha
2003-04-01
The isoprenoid path way produces endogenous digoxin, a substance that can regulate neurotransmitter and amino acid transport. Digoxin synthesis and neurotransmitter patterns were assessed in individuals with chronic insomnia. The patterns were compared in those with right hemispheric and left hemispheric dominance. The activity of HMG GoA reductase and serum levels of digoxin, magnesium, tryptophan catabolites, and tyrosine catabolites were measured in individuals with chronic insomnia and in individuals with differing hemispheric dominance. Digoxin synthesis was increased with upregulated tryptophan catabolism (increased levels of serotonin, strychnine, and nicotine), and downregulated tyrosine catabolism (decreased levels of dopamine, noradrenaline, and morphine) in those with chronic insomnia and right hemispheric chemical dominance. Digoxin synthesis was reduced with downregulated tryptophan catabolism (decreased levels of serotonin, strychnine, and nicotine) and upregulated tyrosine catabolism (increased levels of dopamine, noradrenaline, and morphine) in those with normal sleep patterns and left hemispheric chemical dominance. Hypothalamic digoxin plays a central role in the regulation of sleep behavior. Hemispheric chemical dominance in relation to digoxin status is also crucial.

Full Text Available Advertising strategies are some factors in the content and form of advertisements which are intended to have certain effects on ad viewers or potential customers. These effects could be defined as the kind of cognitive responses they are expected to elicit in their audiences. This study examined 39 Iranian TV commercials in seven product categories to identify the most dominant strategies used by the advertisers and investigated the effect of product type on the selection and use of these strategies. The results showed that Iranian TV commercials used a mixture of analytic and effective cognitive strategies among which “elaborating on the reasons to buy”, “explaining the quality appeal” are the most favorite analytic based strategies and use of emotion and mood arising words is the most dominant affective based advertising method. The results also endorse significant effect of product type on types of strategies employed in the ads.

Computers are increasingly used to improve prescribing decisions in the management of long-term conditions however the effects on asthma prescribing remain unclear. We aimed to synthesise the evidence for the use of computerised alerts that identify excessive prescribing of short-acting beta 2 -agonists (SABAs) to improve asthma management for people with asthma. MEDLINE, CINAHL, Embase, Cochrane and Scopus databases (1990-2016) were searched for randomised controlled trials using electronic alerts to identify excessive prescribing of SABAs for people with asthma in primary care. Inclusion eligibility, quality appraisal (Cochrane risk of bias tool) and data extraction were performed by two independent reviewers. Findings were synthesised narratively. A total of 2035 articles were screened and four trials were eligible. Three studies had low risk of bias: one reported a positive effect on our primary outcome of interest, excessive SABA prescribing; another reported positive effects on the ratio of inhaled corticosteroid (ICS)-SABA prescribing, and asthma control; a third reported no effect on outcomes of interest. One study at high risk of bias reported a reduction in exacerbations and primary care consultations. There is some evidence that electronic alerts reduce excessive prescribing of SABAs, when delivered as part of a multicomponent intervention in an integrated health care system. However due to the variation in health care systems, intervention design and outcomes measured, further research is required to establish optimal design of alerting and intervening systems.

A prevalence of gambling disorders is diversified depending on the region of the world. Almost three quarters of pathological gamblers had never sought a professional treatment as well as an assistance in self-help groups. Reasons why they do not initiate a treatment are complex. The aim of the article is to compare barriers to the treatment for people with gambling disorders found in presented study and barriers to alcohol and drug treatment identified in the available literature. The semi structured interviews were applied and conducted with people with gambling disorders, social workers, therapists employed in the addiction treatment facilities, General Practitioners and psychiatrists. Selection of the respondents was based on purposive sampling. In total, 90 interviews were completed. Respondents identified individual barriers as well as structural ones. Individual barriers include internal resistance and a fear of the treatment. In turn structural barriers apply to the organization of the therapy, infrastructure, personnel, and the therapeutic program. A comparison of barriers experienced by people with gambling disorders and substance use disorders showed that they are largely similar, but people with gambling disorders also experience specific barriers. Empirical studies focused specifically on treatment needs of people experiencing gambling disorders may improve an offer of help for them. More adequate treatment options could contribute to the increasing in the number of people who start the treatment. It can result in improving their quality of life and may have positive impact on public health.

Cancer in indigenous people in Latin America and the Caribbean: a review.
Moore, Suzanne P; Forman, David; Piñeros, Marion; Fernández, Sdenka M; de Oliveira Santos, Marceli; Bray, Freddie
2014-02-01
Cancer is a leading cause of death in Latin America but there have been few assessments of the cancer burden for the 10% of the population who are indigenous. Evidence from other world regions suggests cancer survival is poorer for indigenous people than for others due to a greater incidence of case-fatal cancers, later stage at diagnosis, and less cancer treatment. A status report on the cancer profile of indigenous people in Latin America and the Caribbean (LAC) is therefore clearly warranted. We undertook a systematic review of the peer-reviewed literature in academic databases, and considered evidence from cancer registries from 1980, to assess cancer epidemiology among indigenous people in LAC. We identified 35 peer-reviewed articles pertaining to cancer in indigenous people. Rates of cervical cancer in parts of Brazil, Ecuador, and Guyana, stomach cancer rates in regions of Chile and gallbladder rates in Chile and Bolivia, were higher for indigenous compared to others. Breast cancer rates were lower in Ecuador, Brazil, and Chile. Six cancer registries in Brazil provided incidence data but no other reports of incidence, mortality, or survival were identified. There was a paucity of data surrounding the cancer burden of indigenous people in LAC. In view of predicted increases in cancer rates in ensuing decades, and the disparities in burden already experienced by indigenous people in the region, it is imperative that cancer profiles are obtained and cancer control measures identified and prioritized. © 2013 The Authors.

Human Rights and Indigenous Peoples
Directory of Open Access Journals (Sweden)
Garth Nettheim
2009-09-01
Full Text Available The paper begins by noting the low level of reference to Indigenous Australians in the Commonwealth Constitution at the start of Federation, and goes on to discuss the limits to what was achieved by the 1967 amendments. The situation represents a marked contrast with the USA and Canada in terms of treaties and constitutional recognition. In Australia, particularly during the period of the ‘Reconciliation’ process in the 1990s, important steps were taken by Indigenous Australians to identify items of ‘unfinished business’ in a ‘Statement of Indigenous Rights’. But there has been limited progress to meet these aspirations. And Australian law still lacks a tradition of recognition of human rights generally, let alone Indigenous rights. International law, too, largely lacked recognition of human rights, generally prior to the adoption in 1945 of the Charter of the United Nations. The brief references in the Charter were subsequently developed in a range of declarations and of treaties. These applied to people generally, with scant reference to Indigenous peoples. But, since the 1970s, there has been growing international recognition of the rights of Indigenous peoples under existing declarations and treaties. Since the 1990s, in particular, the UN system has established specific mechanisms for addressing such issues. On 13 September 2007, the General Assembly finally adopted a Declaration on the Rights of Indigenous Peoples.

An efficient non-dominated sorting method for evolutionary algorithms.
Fang, Hongbing; Wang, Qian; Tu, Yi-Cheng; Horstemeyer, Mark F
2008-01-01
We present a new non-dominated sorting algorithm to generate the non-dominated fronts in multi-objective optimization with evolutionary algorithms, particularly the NSGA-II. The non-dominated sorting algorithm used by NSGA-II has a time complexity of O(MN(2)) in generating non-dominated fronts in one generation (iteration) for a population size N and M objective functions. Since generating non-dominated fronts takes the majority of total computational time (excluding the cost of fitness evaluations) of NSGA-II, making this algorithm faster will significantly improve the overall efficiency of NSGA-II and other genetic algorithms using non-dominated sorting. The new non-dominated sorting algorithm proposed in this study reduces the number of redundant comparisons existing in the algorithm of NSGA-II by recording the dominance information among solutions from their first comparisons. By utilizing a new data structure called the dominance tree and the divide-and-conquer mechanism, the new algorithm is faster than NSGA-II for different numbers of objective functions. Although the number of solution comparisons by the proposed algorithm is close to that of NSGA-II when the number of objectives becomes large, the total computational time shows that the proposed algorithm still has better efficiency because of the adoption of the dominance tree structure and the divide-and-conquer mechanism.

Scottish fold cats, named for their unique ear shape, have a dominantly inherited osteochondrodysplasia involving malformation in the distal forelimbs, distal hindlimbs and tail, and progressive joint destruction. This study aimed to identify the gene and the underlying variant responsible for the osteochondrodysplasia. DNA samples from 44 Scottish fold and 54 control cats were genotyped using a feline DNA array and a case-control genome-wide association analysis conducted. The gene encoding a calcium permeable ion channel, transient receptor potential cation channel, subfamily V, member 4 (TRPV4) was identified as a candidate within the associated region and sequenced. Stably transfected HEK293 cells were used to compare wild-type and mutant TRPV4 expression, cell surface localisation and responses to activation with a synthetic agonist GSK1016709A, hypo-osmolarity, and protease-activated receptor 2 stimulation. The dominantly inherited folded ear and osteochondrodysplasia in Scottish fold cats is associated with a p.V342F substitution (c.1024G>T) in TRPV4. The change was not found in 648 unaffected cats. Functional analysis in HEK293 cells showed V342F mutant TRPV4 was poorly expressed at the cell surface compared to wild-type TRPV4 and as a consequence the maximum response to a synthetic agonist was reduced. Mutant TRPV4 channels had a higher basal activity and an increased response to hypotonic conditions. Access to a naturally-occurring TRPV4 mutation in the Scottish fold cat will allow further functional studies to identify how and why the mutations affect cartilage and bone development.

To identify the genetic cause of disease in 2 previously unreported families with forms of distal hereditary motor neuropathies (dHMNs). The first family comprises individuals affected by dHMN type V, which lacks the cardinal clinical feature of vocal cord paralysis characteristic of dHMN-VII observed in the second family. Next-generation sequencing was performed on the proband of each family. Variants were annotated and filtered, initially focusing on genes associated with neuropathy. Candidate variants were further investigated and confirmed by dideoxy sequence analysis and cosegregation studies. Thorough patient phenotyping was completed, comprising clinical history, examination, and neurologic investigation. dHMNs are a heterogeneous group of peripheral motor neuron disorders characterized by length-dependent neuropathy and progressive distal limb muscle weakness and wasting. We previously reported a dominant-negative frameshift mutation located in the concluding exon of the SLC5A7 gene encoding the choline transporter (CHT), leading to protein truncation, as the likely cause of dominantly-inherited dHMN-VII in an extended UK family. In this study, our genetic studies identified distinct heterozygous frameshift mutations located in the last coding exon of SLC5A7 , predicted to result in the truncation of the CHT C-terminus, as the likely cause of the condition in each family. This study corroborates C-terminal CHT truncation as a cause of autosomal dominant dHMN, confirming upper limb predominating over lower limb involvement, and broadening the clinical spectrum arising from CHT malfunction.

Full Text Available Given a graph $G$, the total dominator coloring problem seeks a proper coloring of $G$ with the additional property that every vertex in the graph is adjacent to all vertices of a color class. We seek to minimize the number of color classes. We initiate to study this problem on several classes of graphs, as well as finding general bounds and characterizations. We also compare the total dominator chromatic number of a graph with the chromatic number and the total domination number of it.

Full Text Available Context: Congenital cataracts are one of the common eye disorders leading to visual impairment or blindness in children worldwide. We found a Chinese family with autosomal dominant pulverulent cataract. Aims: To identify the pathogenic gene mutation in a Chinese family with autosomal dominant inherited pulverulent cataract. Subjects and Methods: After obtained informed consent, detailed ophthalmic examinations were carried out; genomic DNAs were obtained from seven family members in a three-generation Chinese family with three affected. All exons of candidate genes were amplified by polymerase chain reaction and were sequenced performed by bidirectional sequencing. Results: By sequencing the encoding regions of the candidate genes, a missense mutation (c. 176C>T was detected in gap junction protein alpha 3 genes (GJA3, which resulted in the substitution of highly conserved proline by leucine at codon 59 (p.P59L. The mutation co-segregated with all patients and was absent in 100 normal Chinese controls. Conclusions: The study identified a missense mutation (c. 176C>T in GJA3 gene associated with autosomal dominant congenital pulverulent cataract in a Chinese family. It gave further evidence of phenotype heterogeneity for P59L mutation in GJA3 associated with congenital cataract.

Full Text Available Abstract Background Colon cancer has been classically described by clinicopathologic features that permit the prediction of outcome only after surgical resection and staging. Methods We performed an unsupervised analysis of microarray data from 326 colon cancers to identify the first principal component (PC1 of the most variable set of genes. PC1 deciphered two primary, intrinsic molecular subtypes of colon cancer that predicted disease progression and recurrence. Results Here we report that the most dominant pattern of intrinsic gene expression in colon cancer (PC1 was tightly correlated (Pearson R = 0.92, P -135 with the EMT signature-- both in gene identity and directionality. In a global micro-RNA screen, we further identified the most anti-correlated microRNA with PC1 as MiR200, known to regulate EMT. Conclusions These data demonstrate that the biology underpinning the native, molecular classification of human colon cancer--previously thought to be highly heterogeneous-- was clarified through the lens of comprehensive transcriptome analysis.

Young people's perspectives on health-related risks
Directory of Open Access Journals (Sweden)
Grace Elisabeth Spencer
2008-07-01
Full Text Available Drawing upon current socio-cultural understandings of risk, this study highlights the disjunction between the expert risk discourses that permeate official public health policy and practice, and young people’s own perspectives on health and risk. Data were collected from young people aged 14-16 years through the use of group and individual interviews in a school and community youth centre setting. Findings from this study question the saliency of expert-defined health-related risks to young people’s everyday lives. Young people in this study saw health as closely linked to ‘being happy’. Friendships and a sense of personal achievement were particularly important to participants’ health and well-being. When accounting for their participation in health-related practices identified as ‘risky’ in government policy – such as smoking, alcohol and substance use – young people emphasised the levels of pressure they experienced. Sources of pressure included arguments and bullying, school work, and negative stereotypes of young people in general. These areas indicated young people’s concerns that reach beyond the official prescriptions permeating current health policy.

Our study was initiated to evaluate whether there are differences between the two sides, depending on hand dominance, in densitometry values and quantitative ultrasound parameters (QUS) of the lower limb. One hundred and six women and 44 men were involved. The hand dominance was determined by interview. The bone mineral density (BMD) of the left and the right femoral necks and the calcanei were measured by dual-energy X-ray absorpiometry (DXA). The QUS examination consisted of measuring the attenuation (BUA), the speed of the ultrasound (SOS) and quantitative ultrasound index (QUI) transversing the left and right calcanei. The density of the neck of femur of the non-dominant side did not differ from that of the dominant side. On the other hand, BMD, BUA and the QUI of the calcaneus were higher on the non-dominant side in both genders (p < 0.05 for each parameter). No similar differences were seen for the SOS values. Our study has confirmed the side-to-side differences of the calcaneus in both genders, lower values were found on the dominant side. No similar differences were seen on the femur. The AUC values seemed to be higher on the dominant side, however, these differences were not strictly significant. In the case of peripheral site (heel) measurements, the practical significance of our observations is that they raise the possibility of performing peripheral DXA and QUS examinations of the calcaneus on the dominant side of the patient according to handedness.

Houses built in New England within the last six years, equal to or exceeding energy-efficiency standards from Energy Crafted Homes (ECH) or from DOE's Energy Star Homes are termed energy-efficient for this study. An assumption is that people who purchase houses being newly constructed may request special features including more energy-efficient features. The average house being constructed today is not as energy-efficient as it could easily be; therefore, owners of recently constructed energy-efficient houses may be termed early-adopters of an innovation. It has been demonstrated that early adopters have different personal attitudes and perceptions of an innovation compared to later-adopters. Both types of adopters--owners of recently constructed energy-efficient or energy-inefficient houses, have been surveyed in New England to determine whether their differences are significant enough to be used in identifying future potential early-adopters. Solar houses also are usually energy-efficient, and should be termed an innovation

Heavy-ion dominance near Cluster perigees
Ferradas, C. P.; Zhang, J.-C.; Kistler, L. M.; Spence, H. E.
2015-12-01
Time periods in which heavy ions dominate over H+ in the energy range of 1-40 keV were observed by the Cluster Ion Spectrometry (CIS)/COmposition DIstribution Function (CODIF) instrument onboard Cluster Spacecraft 4 at L values less than 4. The characteristic feature is a narrow flux peak at around 10 keV that extends into low L values, with He+ and/or O+ dominating. In the present work we perform a statistical study of these events and examine their temporal occurrence and spatial distribution. The observed features, both the narrow energy range and the heavy-ion dominance, can be interpreted using a model of ion drift from the plasma sheet, subject to charge exchange losses. The narrow energy range corresponds to the only energy range that has direct drift access from the plasma sheet during quiet times. The drift time to these locations from the plasma sheet is > 30 h, so that charge exchange has a significant impact on the population. We show that a simple drift/loss model can explain the dependence on L shell and MLT of these heavy-ion-dominant time periods.

Ethnic people of the Himalayan regions of India, Nepal, Bhutan and China consume a variety of indigenous fermented milk products made from cows milk as well as yaks milk. These lesser-known ethnic fermented foods are dahi, mohi, chhurpi, somar, philu and shyow. The population of lactic acid bacteria (LAB) ranged from 10(7) to 10(8) cfu/g in these Himalayan milk products. A total of 128 isolates of LAB were isolated from 58 samples of ethnic fermented milk products collected from different places of India, Nepal and Bhutan. Based on phenotypic characterization including API sugar test, the dominant lactic acid bacteria were identified as Lactobacillus bifermentans, Lactobacillus paracasei subsp. pseudoplantarum, Lactobacillus kefir, Lactobacillus hilgardii, Lactobacillus alimentarius, Lactobacillus paracasei subsp. paracasei, Lactobacillus plantarum, Lactococcus lactis subsp. lactis, Lactococcus lactis subsp. cremoris and Enterococcus faecium. LAB produced a wide spectrum of enzymes and showed high galactosidase, leucine-arylamidase and phosphatase activities. They showed antagonistic properties against selected Gram-negative bacteria. None of the strains produced bacteriocin and biogenic amines under the test conditions used. Most strains of LAB coagulated skim milk with a moderate drop in pH. Some strains of LAB showed a high degree of hydrophobicity, suggesting these strains may have useful adhesive potential. This paper is the first report on functional lactic acid bacterial composition in some lesser-known ethnic fermented milk products of the Himalayas.

Discrimination in the health care system has a direct negative impact on health and wellbeing. Experiences of discrimination are considered a root cause for the health inequalities that exist among Indigenous peoples. Experiences of discrimination are commonplace, with patients noting abusive treatment, stereotyping, and a lack of quality in the care provided, which discourage Indigenous people from accessing care. This research project examined the perspectives of health care providers and decision-makers to identify what challenges they see facing Indigenous patients and families when accessing health services in a large city in southern Ontario. Discrimination against Indigenous people was identified as major challenges by respondents, noting that it is widespread. This paper discusses the three key discrimination subthemes that were identified, including an unwelcoming environment, stereotyping and stigma, and practice informed by racism. These findings point to the conclusion that in order to improve health care access for Indigenous peoples, we need to go beyond simply making health services more welcoming and inclusive. Practice norms shaped by biases informed by discrimination against Indigenous people are widespread and compromise standards of care. Therefore, the problem needs to be addressed throughout the health care system as part of a quality improvement strategy. This will require not only a significant shift in the attitudes, knowledge, and skills of health care providers, but also the establishment of accountabilities for health care organizations to ensure equitable health services for Indigenous peoples.

Perceptions of disaster preparedness among older people in South Korea.
Yoo, Myoungran; Lee, Mijung; Tullmann, Dorothy
2016-03-01
Older people are a major vulnerable population. During disasters, given their physical frailty, lower social status, loss of medications and medical care, the vulnerability of older people increases. The purpose of this study was to examine the perceptions of older people in Korea on various aspects of disaster preparedness to better understand their special needs and to facilitate appropriate disaster planning. The study was qualitative and used focus group interviews with 12 older people in one major city and one rural area of South Korea. Four themes were identified by the analysis of the interviews: defenceless state, reality of accepting limitations, strong will to live, importance of disaster preparedness governmental efforts for the older people. Findings indicated that preparation of shelters and transportation was critical to help older people survive in times of disasters and suggested that there should be active involvement of the government in terms of disaster planning, managing and preparing older people for disasters. In addition, healthy older people can be assets to disaster relief efforts by providing practical and emotional support for the most fragile older people. Older people can also provide knowledge of their special needs to the government to improve their disaster response policy. © 2015 John Wiley & Sons Ltd.

Studies have documented the perceived needs of carers of people with psychosis but most recruitment has utilised convenience sampling resulting in limited understanding of carers' needs. This longitudinal study was conducted within the second Australian prevalence study of psychosis, aiming to obtain generalisable findings regarding perceived needs of carers of people with psychosis. Semi-structured interviews were conducted with 98 carers of people with psychosis recruited in the Australian prevalence study of psychosis. Seventy-eight of the carers were reinterviewed 1 year later to measure changes in their perceived needs. Correlational and paired T tests were conducted to identify relationships between perceived needs and carer's health and well-being, and changes in levels of perceived needs over time. Qualitative responses were structurally coded by segmentation according to the Carers' and Users' Expectations of Services-Carer version. Thematic analysis of common words and phrases was undertaken to identify key themes concerning carers' perceived needs. There was minimal improvement in carers' perceived needs over time and their needs were closely related to their perception of their own social connectedness, psychological health and quality of life. Five themes were identified: Greater involvement of carers in the treatment plan, provision of relevant information to carers, multiple biopsychosocial support for carers, well-being and independence interventions for people with psychosis, and choice to care and alternate caring arrangements. Although policy recognises the need to support carers, findings show that focused interventions are required to address carers' perceived needs more holistically in current mental health services. To support carers' recovery, services need to include carers in treatment planning, and consider ways to address their needs and improve their own health and well-being. © 2017 John Wiley & Sons Ltd.

2013-09-01
The burden of tuberculosis (TB) in the estimated 370 million indigenous peoples worldwide is unknown. To conduct a literature review to summarize the TB burden in indigenous peoples, identify gaps in current knowledge, and provide the foundation for a research agenda prioritizing indigenous health within TB control. A systematic literature review identified articles published between January 1990 and November 2011 quantifying TB disease burden in indigenous populations worldwide. Among the 91 articles from 19 countries included in the review, only 56 were from outside Australia, Canada, New Zealand and the United States. The majority of the studies showed higher TB rates among indigenous groups than non-indigenous groups. Studies from the Amazon generally reported the highest TB prevalence and incidence, but select populations from South-East Asia and Africa were found to have similarly high rates of TB. In North America, the Inuit had the highest reported TB incidence (156/100000), whereas the Metis of Canada and American Indians/Alaska Natives experienced rates of indigenous groups. Where data exist, indigenous peoples were generally found to have higher rates of TB disease than non-indigenous peoples; however, this burden varied greatly. The paucity of published information on TB burden among indigenous peoples highlights the need to implement and improve TB surveillance to better measure and understand global disparities in TB rates.

Full Text Available Abstract Background Case descriptions suggest IBS patients are more likely to have other disorders, including migraine, fibromyalgia, and depression. We sought to examine the prevalence of these conditions in cohorts of people with and without IBS. Methods The source of data was a large U.S. health plan from January 1, 1996 though June 30, 2002. We identified all people with a medical claim associated with an ICD-9 code for IBS. A non-IBS cohort was a random sample of people with an ICD-9 code for routine medical care. In the cohorts, we identified all claims for migraine, depression, and fibromyalgia. We estimated the prevalence odds ratios (PORs of each of the three conditions using the Mantel-Haenszel method. We conducted quantitative sensitivity analyses to quantify the impact of residual confounding and in differential outcome identification. Results We identified 97,593 people in the IBS cohort, and a random sample of 27,402 people to compose the non-IBS comparison cohort. With adjustment, there was a 60% higher odds in the IBS cohort of having any one of the three disorders relative to the comparison cohort (POR 1.6, 95% CI 1.5 – 1.7. There was a 40% higher odds of depression in the IBS cohort (POR 1.4, 95% CI 1.3 – 1.4. The PORs for fibromyalgia and migraine were similar (POR for fibromyalgia 1.8, 95% CI 1.7 – 1.9; POR for migraine 1.6, 95% CI 1.4 – 1.7. Differential prevalence of an unmeasured confounder, or imperfect sensitivity or specificity of outcome detection would have impacted the observed results. Conclusion People in the IBS cohort had a 40% to 80% higher prevalence odds of migraine, fibromyalgia, and depression.

Full Text Available Dominance is defined as the preferential access to limited resources. The present study aimed to characterise dominance in a non-aggressive flatfish species, the Senegalese sole (Solea senegalensis by 1 identifying dominance categories and associated behaviours and 2 linking dominance categories (dominant and subordinate with the abundance of selected mRNA transcripts in the brain. Early juveniles (n = 74, 37 pairs were subjected to a dyadic dominance test, related to feeding, and once behavioural phenotypes had been described the abundance of ten selected mRNAs related to dominance and aggressiveness was measured in the brain. Late juveniles were subjected to two dyadic dominance tests (n = 34, 17 pairs, related to feeding and territoriality and one group test (n = 24, 4 groups of 6 fish. Sole feeding first were categorized as dominant and sole feeding second or not feeding as subordinate. Three social behaviours (i. "Resting the head" on another fish, ii. "Approaching" another fish, iii. "Swimming above another" fish were associated with dominance of feeding. Two other variables (i. Total time occupying the preferred area during the last 2 hours of the 24 h test, ii. Organisms occupying the preferred area when the test ended were representative of dominance in the place preference test. In all tests, dominant fish compared to subordinate fish displayed a significantly higher number of the behaviours "Rest the head" and "Approaches". Moreover, dominant sole dominated the sand at the end of the test, and in the group test dominated the area close to the feed delivery point before feed was delivered. The mRNA abundance of the selected mRNAs related to neurogenesis (nrd2 and neuroplasticity (c-fos in dominant sole compared to subordinate were significantly different. This is the first study to characterise dominance categories with associated behaviours and mRNA abundance in Senegalese sole and provides tools to study dominance related problems in

Why large cells dominate estuarine phytoplankton
Cloern, James E.
2018-01-01
Surveys across the world oceans have shown that phytoplankton biomass and production are dominated by small cells (picoplankton) where nutrient concentrations are low, but large cells (microplankton) dominate when nutrient-rich deep water is mixed to the surface. I analyzed phytoplankton size structure in samples collected over 25 yr in San Francisco Bay, a nutrient-rich estuary. Biomass was dominated by large cells because their biomass selectively grew during blooms. Large-cell dominance appears to be a characteristic of ecosystems at the land–sea interface, and these places may therefore function as analogs to oceanic upwelling systems. Simulations with a size-structured NPZ model showed that runs of positive net growth rate persisted long enough for biomass of large, but not small, cells to accumulate. Model experiments showed that small cells would dominate in the absence of grazing, at lower nutrient concentrations, and at elevated (+5°C) temperatures. Underlying these results are two fundamental scaling laws: (1) large cells are grazed more slowly than small cells, and (2) grazing rate increases with temperature faster than growth rate. The model experiments suggest testable hypotheses about phytoplankton size structure at the land–sea interface: (1) anthropogenic nutrient enrichment increases cell size; (2) this response varies with temperature and only occurs at mid-high latitudes; (3) large-cell blooms can only develop when temperature is below a critical value, around 15°C; (4) cell size diminishes along temperature gradients from high to low latitudes; and (5) large-cell blooms will diminish or disappear where planetary warming increases temperature beyond their critical threshold.

Background: People with intellectual disabilities (ID) are as likely as the general population to find themselves in the situation of having to identify and/or describe a perpetrator's face to the police. However, limited verbal and memory abilities in people with ID might prevent them to engage in standard police procedures. Method: Two…

Why social dominance theory has been falsified.
Turner, John C; Reynolds, Katherine J
2003-06-01
Schmitt, Branscombe and Kappen (2003) and Wilson and Lui (2003) present a persuasive series of studies which raise major problems for the conceptualization of social dominance orientation in social dominance theory. Building on these and other data in the literature, this commentary summarizes six fundamental criticisms which can be made of the theory. We conclude that social dominance theory is flawed by conceptual inconsistencies and has been disconfirmed empirically in relation to its key hypothesis of behavioural asymmetry. The reaction of subordinate groups to the social hierarchy is better explained by social identity theory.

The 4C framework for making reasonable adjustments for people with learning disabilities.
Marsden, Daniel; Giles, Rachel
2017-01-18
Background People with learning disabilities experience significant inequalities in accessing healthcare. Legal frameworks, such as the Equality Act 2010, are intended to reduce such disparities in care, and require organisations to make 'reasonable adjustments' for people with disabilities, including learning disabilities. However, reasonable adjustments are often not clearly defined or adequately implemented in clinical practice. Aim To examine and synthesise the challenges in caring for people with learning disabilities to develop a framework for making reasonable adjustments for people with learning disabilities in hospital. This framework would assist ward staff in identifying and managing the challenges of delivering person-centred, safe and effective healthcare to people with learning disabilities in this setting. Method Fourth-generation evaluation, collaborative thematic analysis, reflection and a secondary analysis were used to develop a framework for making reasonable adjustments in the hospital setting. The authors attended ward manager and matron group meetings to collect their claims, concerns and issues, then conducted a collaborative thematic analysis with the group members to identify the main themes. Findings Four main themes were identified from the ward manager and matron group meetings: communication, choice-making, collaboration and coordination. These were used to develop the 4C framework for making reasonable adjustments for people with learning disabilities in hospital. Discussion The 4C framework has provided a basis for delivering person-centred care for people with learning disabilities. It has been used to inform training needs analyses, develop audit tools to review delivery of care that is adjusted appropriately to the individual patient; and to develop competencies for learning disability champions. The most significant benefit of the 4C framework has been in helping to evaluate and resolve practice-based scenarios. Conclusion Use of

The aim of the study was to determine the applicability of magnetic stimulation and magnetic motor evoked potentials (MEPs) in motor asymmetry studies by obtaining quantitative and qualitative measures of efferent activity during low intensity magnetic stimulation of the dominant and non-dominant lower extremities. Magnetic stimulation of the tibial nerve in the popliteal fossa was performed in 10 healthy male right-handed and right-footed young adults. Responses were recorded from the lateral head of the gastrocnemius muscles of the right and left lower extremities. Response characteristics (duration, onset latency, amplitude) were analyzed in relation to the functional dominance of the limbs and in relation to the direction of the current in the magnetic coil by use of the Wilcoxon pair sequence test. The CCW direction of coil current was related to reduced amplitudes of recorded MEPs. Greater amplitudes of evoked potentials were recorded in the non-dominant extremity, both in the CW and CCW coil current directions, with the statistical significance of this effect (p=0.005). No differences in duration of response were found in the CW current direction, while in CCW the time of the left-side response was prolonged (p=0.01). In the non-dominant extremity longer onset latencies were recorded in both current directions, but only for the CW direction the side asymmetries showed a statistical significance of p=0.005. In the dominant extremity the stimulation correlated with stronger paresthesias, especially using the CCW direction of coil current. The results indicate that low intensity magnetic stimulation may be useful in quantitative and qualitative research into the motor asymmetry.

Nurses' understandings of suitable footwear for older people.
Borland, Andrea; Martin, Caroline Hollins; Locke, John
2013-01-01
The purpose of this paper is to gain insight into nurses' understandings of what constitutes suitable footwear for older people in care homes. An exploratory descriptive qualitative survey was carried out of 20 registered nurses employed in six Scottish care homes for older people. Data were collected using a semi-structured questionnaire that included five open-ended questions. Content analysis was used to theme footwear perceptions. Participants had several views about what encompasses safe footwear; some were erroneous. The link between inappropriate footwear and falls was recognised by 80 per cent of respondents, but some were unclear about the features that effect or inhibit safety. No UK or international standardised guidelines were identified that advise nurses about appropriate footwear for older people. It is unknown whether respondents represent the nurse population because findings are restricted by a small sample size. Nonetheless, the group showed variable understanding of what constitutes safe footwear for older people and links with fall prevention. Improved nurse-education about what comprises safe footwear and the links with falls prevention in older people is required. Structured guidelines to direct nurse educators about what to teach student nurses about appropriate footwear for older people may work towards reducing falls. No guidelines to direct nurses about appropriate footwear for older people in care homes have been written. Key points have been developed.

Footwear Experiences of People With Chronic Musculoskeletal Diseases.
Hendry, Gordon J; Brenton-Rule, Angela; Barr, Georgina; Rome, Keith
2015-08-01
Foot pain and deformities are frequently reported by people with chronic musculoskeletal diseases, but only limited research has been conducted to explore the key issues concerning footwear difficulties in this population. The aim of this study is to explore, identify, and describe the main issues surrounding the footwear experiences of people with chronic musculoskeletal diseases. A qualitative manifest content analysis of open-ended survey responses concerning footwear experiences was conducted from a national footwear survey of people with chronic musculoskeletal diseases in New Zealand. Eighty-five respondents submitted usable responses. Specific statements in the text were identified as units of analysis prior to coding and organizing these units into emerging mutually exclusive categories. Content analysis was independently undertaken by 3 researchers, and the final categories and coding were achieved through consensus. Frequencies of assigned units of analysis were calculated in order to obtain a quantitative description for each category. Four categories encompassing a total of 9 subcategories related to the footwear experiences of respondents emerged from the qualitative data content analysis: difficulty finding appropriate footwear; dissatisfaction with therapeutic footwear provision and foot care access; high costs of footwear, foot care, and self-care; and satisfaction with therapeutic footwear and foot care. Key categories describing the important issues surrounding the footwear experiences of respondents with chronic musculoskeletal diseases were identified, which may provide important targets for improving footwear and foot care services and self-management strategies. © 2015, American College of Rheumatology.

Full Text Available BACKGROUND: Chromatin organizational and topological plasticity, and its functions in gene expression regulation, have been strongly revealed by the analysis of nucleolar dominance in hybrids and polyploids where one parental set of ribosomal RNA (rDNA genes that are clustered in nucleolar organizing regions (NORs, is rendered silent by epigenetic pathways and heterochromatization. However, information on the behaviour of dominant NORs is very sparse and needed for an integrative knowledge of differential gene transcription levels and chromatin specific domain interactions. METHODOLOGY/PRINCIPAL FINDINGS: Using molecular and cytological approaches in a wheat-rye addition line (wheat genome plus the rye nucleolar chromosome pair 1R, we investigated transcriptional activity and chromatin topology of the wheat dominant NORs in a nucleolar dominance situation. Herein we report dominant NORs up-regulation in the addition line through quantitative real-time PCR and silver-staining technique. Accompanying this modification in wheat rDNA trascription level, we also disclose that perinucleolar knobs of ribosomal chromatin are almost transcriptionally silent due to the residual detection of BrUTP incorporation in these domains, contrary to the marked labelling of intranucleolar condensed rDNA. Further, by comparative confocal analysis of nuclei probed to wheat and rye NORs, we found that in the wheat-rye addition line there is a significant decrease in the number of wheat-origin perinucleolar rDNA knobs, corresponding to a diminution of the rDNA heterochromatic fraction of the dominant (wheat NORs. CONCLUSIONS/SIGNIFICANCE: We demonstrate that inter-specific interactions leading to wheat-origin NOR dominance results not only on the silencing of rye origin NOR loci, but dominant NORs are also modified in their transcriptional activity and interphase organization. The results show a cross-talk between wheat and rye NORs, mediated by ribosomal chromatin

Reefs and People at Risk Increasing levels of carbon dioxide in the atmosphere put shallow, warm-water coral reef ecosystems, and the people who depend upon them at risk from two key global environmental stresses: 1) elevated sea surface temperature (that can cause coral bleaching and related mortality), and 2) ocean acidification. These global stressors: cannot be avoided by local management, compound local stressors, and hasten the loss of ecosystem services. Impacts to people will be most grave where a) human dependence on coral reef ecosystems is high, b) sea surface temperature reaches critical levels soonest, and c) ocean acidification levels are most severe. Where these elements align, swift action will be needed to protect people’s lives and livelihoods, but such action must be informed by data and science. An Indicator Approach Designing policies to offset potential harm to coral reef ecosystems and people requires a better understanding of where CO2-related global environmental stresses could cause the most severe impacts. Mapping indicators has been proposed as a way of combining natural and social science data to identify policy actions even when the needed science is relatively nascent. To identify where people are at risk and where more science is needed, we map indicators of biological, physical and social science factors to understand how human dependence on coral reef ecosystems will be affected by globally-driven threats to corals expected in a high-CO2 world. Western Mexico, Micronesia, Indonesia and parts of Australia have high human dependence and will likely face severe combined threats. As a region, Southeast Asia is particularly at risk. Many of the countries most dependent upon coral reef ecosystems are places for which we have the least robust data on ocean acidification. These areas require new data and interdisciplinary scientific research to help coral reef-dependent human communities better prepare for a high CO2 world. PMID:27828972

A profile of technology-assisted children and young people in north west England.
Kirk, Susan
2008-11-01
To obtain a profile of children and young people in north west England who needed the ongoing support of medical technology. As part of a larger study, 28 community children's nursing teams in the north west of England were asked to profile the children and young people on their caseloads who needed the ongoing support of medical technology. Twenty-five teams returned data, from which a total of 591 children and young people were identified. The most prevalent technology used was gastrostomy/jejunostomy, which was used by more than two-thirds of the sample. Over a quarter of the children/young people were supported by more than one technology. The majority of the children/young people were seven years old or younger Although most had used the technology for five years or less (71 per cent), there were 164 children/ young people who had been technology-assisted for six or more years. Although there are limitations in this study, the data is nevertheless useful for planning future services and support, including identifying the numbers of young people who will be transferring to adult services. A more efficient means of collecting these data would be to systematically record long-term conditions and technology assistance in electronic health records.

A4 see-saw models and form dominance
International Nuclear Information System (INIS)
Chen, M-C; King, Stephen F.
2009-01-01
We introduce the idea of Form Dominance in the (type I) see-saw mechanism, according to which a particular right-handed neutrino mass eigenstate is associated with a particular physical neutrino mass eigenstate, leading to a form diagonalizable effective neutrino mass matrix. Form Dominance, which allows an arbitrary neutrino mass spectrum, may be regarded as a generalization of Constrained Sequential Dominance which only allows strongly hierarchical neutrino masses. We consider alternative implementations of the see-saw mechanism in minimal A 4 see-saw models and show that such models satisfy Form Dominance, leading to neutrino mass sum rules which predict closely spaced neutrino masses with a normal or inverted neutrino mass ordering. To avoid the partial cancellations inherent in such models we propose Natural Form Dominance, in which a different flavon is associated with each physical neutrino mass eigenstate.

Autosomal-dominant osteopetrosis: An incidental finding
Directory of Open Access Journals (Sweden)
Rajathi Maria
2010-01-01
Full Text Available Osteopetrosis is a descriptive term that refers to a group of rare, heritable disorders of the skeleton. Osteopetrotic conditions vary greatly in their presentation and severity, from just as an incidental finding on radiographs to causing life-threatening complications such as bone marrow suppression. It is caused by failure of osteoclast development and function. Osteopetrosis can be inherited as autosomal-recessive, autosomal-dominant or as X-linked traits, with the most severe forms being the autosomal-recessive ones. The severity of the disease is mild to moderate in the autosomal-dominant forms, with normal life expectancy. Diagnosis is largely based on clinical and radiographic evaluation. The present paper reports a case of autosomal-dominant osteopetrosis complicated by osteomyelitis with a short review of the condition.

The experience of women in male-dominated occupations: A constructivist grounded theory inquiry
Directory of Open Access Journals (Sweden)
Phiona Martin
2013-06-01
Full Text Available Orientation: Women in male-dominated occupations face unique challenges and use distinct coping strategies affecting their motivation and retention in these occupations. Research purpose: The purpose was to explore the experiences of women working in maledominated occupations to clarify the challenges they face and identify coping strategies that enable them to continue on their career paths. Motivation for the study: Many women who choose male-dominated careers soon change in favour of more female-dominated or gender-balanced career paths. An understanding of women’s experiences may facilitate strategies geared towards their motivation and retention in male-dominated occupations. Research design, approach and method: The authors conducted this exploratory qualitative study from a constructivist grounded theory perspective. They used a purposive sample of five women and conducted in-depth unstructured interviews. They analysed data using a constructivist grounded theory methodology. Main findings: The authors found that formal and covert organisational practices, which upheld gender discrimination and bias, were the main challenges that women face. These practices included the inadequate accommodation of women’s unique physical, identity and work-life balance needs. Elements of women’s resilience included the use of femininity, adopting male characteristics, mentorship and intrinsic motivational factors. Practical/managerial implications: The findings may guide organisations to develop and implement policies, strategies and initiatives geared towards attracting, integrating, retaining, supporting and motivating women who are, or wish to be, employed in historically maledominated occupations. Contribution/value-add: This study contributes to an evolving body of knowledge aimed at understanding how to integrate and retain women in male-dominated occupations better.

Paresthesia-dominant and pain-dominant subgroups have been noted in carpal tunnel syndrome (CTS), a peripheral neuropathic disorder characterized by altered primary somatosensory/motor (S1/M1) physiology. We aimed to investigate whether brain morphometry dissociates these subgroups. Subjects with CTS were evaluated with nerve conduction studies, whereas symptom severity ratings were used to allocate subjects into paresthesia-dominant (CTS-paresthesia), pain-dominant (CTS-pain), and pain/paresthesia nondominant (not included in further analysis) subgroups. Structural brain magnetic resonance imaging data were acquired at 3T using a multiecho MPRAGE T1-weighted pulse sequence, and gray matter cortical thickness was calculated across the entire brain using validated, automated methods. CTS-paresthesia subjects demonstrated reduced median sensory nerve conduction velocity (P = 0.05) compared with CTS-pain subjects. In addition, cortical thickness in precentral and postcentral gyri (S1/M1 hand area) contralateral to the more affected hand was significantly reduced in CTS-paresthesia subgroup compared with CTS-pain subgroup. Moreover, in CTS-paresthesia subjects, precentral cortical thickness was negatively correlated with paresthesia severity (r(34) = -0.40, P = 0.016) and positively correlated with median nerve sensory velocity (r(36) = 0.51, P = 0.001), but not with pain severity. Conversely, in CTS-pain subjects, contralesional S1 (r(9) = 0.62, P = 0.042) and M1 (r(9) = 0.61, P = 0.046) cortical thickness were correlated with pain severity, but not median nerve velocity or paresthesia severity. This double dissociation in somatotopically specific S1/M1 areas suggests a neuroanatomical substrate for symptom-based CTS subgroups. Such fine-grained subgrouping of CTS may lead to improved personalized therapeutic approaches, based on superior characterization of the linkage between peripheral and central neuroplasticity.

Enjoyment of exercise among people with arthritis: An inductive thematic analysis.
Kibblewhite, Julia R; Treharne, Gareth J; Stebbings, Simon; Hegarty, Roisin Sm
2017-09-01
Past research into exercise among people with long-term health conditions has paid surprisingly little attention to the concept of enjoyment. This study explored enjoyment of exercise among people with arthritis. Semi-structured interviews were held with 12 participants aged 20-85 years. The transcripts were analysed using inductive thematic analysis. Four themes were identified: enjoyment of exercise in relation to other people, benefits of exercise in relation to enjoyment, working around barriers to enjoy exercise and finding an enjoyable balance to exercise. These themes highlight the relevance of enjoyment and how it could feature in advice about exercise for people with arthritis.

A motivation-based explanatory model of street drinking among young people.
Martín-Santana, Josefa D; Beerli-Palacio, Asunción; Fernández-Monroy, Margarita
2014-01-01
This social marketing study focuses on street drinking behavior among young people. The objective is to divide the market of young people who engage in this activity into segments according to their motivations. For the three segments identified, a behavior model is created using the beliefs, attitudes, behavior, and social belonging of young people who engage in street drinking. The methodology used individual questionnaires filled in by a representative sample of young people. The results show that the behavior model follows the sequence of attitudes-beliefs-behavior and that social belonging influences these three variables. Similarly, differences are observed in the behavior model depending on the segment individuals belong to.

Neural underpinnings of the identifiable victim effect: affect shifts preferences for giving.
Genevsky, Alexander; Västfjäll, Daniel; Slovic, Paul; Knutson, Brian
2013-10-23
The "identifiable victim effect" refers to peoples' tendency to preferentially give to identified versus anonymous victims of misfortune, and has been proposed to partly depend on affect. By soliciting charitable donations from human subjects during behavioral and neural (i.e., functional magnetic resonance imaging) experiments, we sought to determine whether and how affect might promote the identifiable victim effect. Behaviorally, subjects gave more to orphans depicted by photographs versus silhouettes, and their shift in preferences was mediated by photograph-induced feelings of positive arousal, but not negative arousal. Neurally, while photographs versus silhouettes elicited activity in widespread circuits associated with facial and affective processing, only nucleus accumbens activity predicted and could statistically account for increased donations. Together, these findings suggest that presenting evaluable identifiable information can recruit positive arousal, which then promotes giving. We propose that affect elicited by identifiable stimuli can compel people to give more to strangers, even despite costs to the self.

Feng Jiang
Full Text Available To investigate the association between ocular sensory dominance and interocular refractive error difference (IRED.A total of 219 subjects were recruited. The refractive errors were determined by objective refraction with a fixation target located 6 meters away. 176 subjects were myopic, with 83 being anisometropic (IRED ≥ 0.75 D. 43 subjects were hyperopic, with 22 being anisometropic. Sensory dominance was measured with a continuous flashing technique with the tested eye viewing a Gabor increasing in contrast and the fellow eye viewing a Mondrian noise decreasing in contrast. The log ratio of Mondrian to Gabor's contrasts was recorded when a subject just detected the tilting direction of the Gabor during each trial. T-test was used to compare the 50 values collected from each eye, and the t-value was used as a subject's ocular dominance index (ODI to quantify the degree of ocular dominance. A subject with ODI ≥ 2 (p < 0.05 had clear dominance and the eye with larger mean ratio was the dominant one. Otherwise, a subject had an unclear dominance.The anisometropic subjects had stronger ocular dominance in comparison to non-anisometropic subjects (rank-sum test, p < 0.01 for both myopic and hyperopic subjects. In anisometropic subjects with clear dominance, the amplitude of the anisometropia was correlated with ODI values (R = 0.42, p < 0.01 in myopic anisometropic subjects; R = 0.62, p < 0.01 in hyperopic anisometropic subjects. Moreover, the dominant eyes were more myopic in myopic anisometropic subjects (sign-test, p < 0.05 and less hyperopic in hyperopic anisometropic subjects (sign-test, p < 0.05.The degree of ocular sensory dominance is associated with interocular refractive error difference.

Gregor Wolbring
2016-09-01
Full Text Available Genetic researchers are advancing in their abilities to extract precise genetic information from biological and human entities bringing genetic research steps closer to accurately modifying genes of biological entities, including that of humans. In this analytical essay, we focus on the discussions about precision genetic intervention that have taken place since March 2015 as they pertain to disabled people. We focus on two areas; one being the role of disabled people in the recent gene editing discussions and the second being the utility of existing legal instruments. Within our first focus we address the following questions: (a What is the visibility of disabled people in the gene-editing discussions that have taken place since March 2015? (b What has been the impact of those discussions on disabled people? (c Were social problems which disabled people face taken into account in those discussions; (d How does the reality of engagement with disabled people in these discussions fit with science, technology and innovation governance discourses that ask for more stakeholder, bottom up and anticipatory involvement? Within our second focus we address the following questions: (a What is the utility of the United Nations Convention on the Right of Persons with Disabilities (UNCRPD; and (b What is the utility of existing legal instruments covering genetic interventions: for preventing negative social consequences of genetic engineering developments for disabled people. We argue that (a the genetic engineering debates since March 2015 have portrayed disabled people dominantly through a medical lens; (b that the governance of science, technology and innovation of genetic engineering including anticipatory governance and responsible innovation discourses has not yet engaged with the social impact of gene editing on disabled people; (c that few scholars that focus on the social situation of disabled people are visible in the governance discussions of gene

Full Text Available Abstract Background The Signal-to-Noise-Ratio (SNR is often used for identification of biomarkers for two-class problems and no formal and useful generalization of SNR is available for multiclass problems. We propose innovative generalizations of SNR for multiclass cancer discrimination through introduction of two indices, Gene Dominant Index and Gene Dormant Index (GDIs. These two indices lead to the concepts of dominant and dormant genes with biological significance. We use these indices to develop methodologies for discovery of dominant and dormant biomarkers with interesting biological significance. The dominancy and dormancy of the identified biomarkers and their excellent discriminating power are also demonstrated pictorially using the scatterplot of individual gene and 2-D Sammon's projection of the selected set of genes. Using information from the literature we have shown that the GDI based method can identify dominant and dormant genes that play significant roles in cancer biology. These biomarkers are also used to design diagnostic prediction systems. Results and discussion To evaluate the effectiveness of the GDIs, we have used four multiclass cancer data sets (Small Round Blue Cell Tumors, Leukemia, Central Nervous System Tumors, and Lung Cancer. For each data set we demonstrate that the new indices can find biologically meaningful genes that can act as biomarkers. We then use six machine learning tools, Nearest Neighbor Classifier (NNC, Nearest Mean Classifier (NMC, Support Vector Machine (SVM classifier with linear kernel, and SVM classifier with Gaussian kernel, where both SVMs are used in conjunction with one-vs-all (OVA and one-vs-one (OVO strategies. We found GDIs to be very effective in identifying biomarkers with strong class specific signatures. With all six tools and for all data sets we could achieve better or comparable prediction accuracies usually with fewer marker genes than results reported in the literature using the

Fast Reduction Method in Dominance-Based Information Systems
Li, Yan; Zhou, Qinghua; Wen, Yongchuan
2018-01-01
In real world applications, there are often some data with continuous values or preference-ordered values. Rough sets based on dominance relations can effectively deal with these kinds of data. Attribute reduction can be done in the framework of dominance-relation based approach to better extract decision rules. However, the computational cost of the dominance classes greatly affects the efficiency of attribute reduction and rule extraction. This paper presents an efficient method of computing dominance classes, and further compares it with traditional method with increasing attributes and samples. Experiments on UCI data sets show that the proposed algorithm obviously improves the efficiency of the traditional method, especially for large-scale data.

2014-06-01
Fungal spores are widespread and common in the atmosphere. In this study, we use a metagenomic approach to study the fungal diversity in six total air samples collected from April to May 2012 in Seoul, Korea. This springtime period is important in Korea because of the peak in fungal spore concentration and Asian dust storms, although the year of this study (2012) was unique in that were no major Asian dust events. Clustering sequences for operational taxonomic unit (OTU) identification recovered 1,266 unique OTUs in the combined dataset, with between 223᾿96 OTUs present in individual samples. OTUs from three fungal phyla were identified. For Ascomycota, Davidiella (anamorph: Cladosporium) was the most common genus in all samples, often accounting for more than 50% of all sequences in a sample. Other common Ascomycota genera identified were Alternaria, Didymella, Khuskia, Geosmitha, Penicillium, and Aspergillus. While several Basidiomycota genera were observed, Chytridiomycota OTUs were only present in one sample. Consistency was observed within sampling days, but there was a large shift in species composition from Ascomycota dominant to Basidiomycota dominant in the middle of the sampling period. This marked change may have been caused by meteorological events. A potential set of 40 allergy-inducing genera were identified, accounting for a large proportion of the diversity present (22.5᾿7.2%). Our study identifies high fungal diversity and potentially high levels of fungal allergens in springtime air of Korea, and provides a good baseline for future comparisons with Asian dust storms.

Sibling rivalry: training effects, emergence of dominance and incomplete control.
Benhaiem, Sarah; Hofer, Heribert; Kramer-Schadt, Stephanie; Brunner, Edgar; East, Marion L
2012-09-22
Within-brood or -litter dominance provides fitness-related benefits if dominant siblings selfishly skew access to food provided by parents in their favour. Models of facultative siblicide assume that dominants exert complete control over their subordinate sibling's access to food and that control is maintained, irrespective of the subordinate's hunger level. By contrast, a recent functional hypothesis suggests that subordinates should contest access to food when the cost of not doing so is high. Here, we show that within spotted hyena (Crocuta crocuta) twin litters, dominants most effectively skew access to maternal milk in their favour when their aggression prompts a highly submissive response. When hungry, subordinates were less submissive in response to aggression, thereby decreasing lost suckling time and increasing suckling time lost by dominants. In a species where adult females socially dominate adult males, juvenile females were more often dominant than males in mixed-sex litters, and subordinate sisters used more effective counter-tactics against dominant brothers than subordinate brothers against dominant sisters. Our results provide, to our knowledge, the first evidence in a mammal that dominant offspring in twin litters do not exert complete control over their sibling's access to resources (milk), and that sibling dominance relationships are influenced by sibling sex and training effects.

By means of a combined use of the type Ia supernovae and H(z) data tests, together with the study of the asymptotic properties in the equivalent phase space — through the use of the dynamical systems tools — we demonstrate that the bulk viscous matter-dominated scenario is not a good model to explain the accepted cosmological paradigm, at least, under the parametrization of bulk viscosity considered in this paper. The main objection against such scenarios is the absence of conventional radiation and matter-dominated critical points in the phase space of the model. This entails that radiation and matter dominance are not generic solutions of the cosmological equations, so that these stages can be implemented only by means of unique and very specific initial conditions, i. e., of very unstable particular solutions. Such a behavior is in marked contradiction with the accepted cosmological paradigm which requires of an earlier stage dominated by relativistic species, followed by a period of conventional non-relativistic matter domination, during which the cosmic structure we see was formed. Also, we found that the bulk viscosity is positive just until very late times in the cosmic evolution, around z < 1. For earlier epochs it is negative, been in tension with the local second law of thermodynamics.

What matters most to people in musculoskeletal physiotherapy consultations? A qualitative study.
Stenner, Rob; Palmer, Shea; Hammond, Ralph
2018-06-01
Person-centred approaches to care require clinicians to engage in trying to understand the full range of problems and concerns, treatment and investigation requests, and emotional and social issues that people bring to the consultation. If, however, the main issues of importance are not openly declared and discussed they cannot be addressed. This is likely to result in people receiving the care that clinicians think they need, rather than care based on individual needs and preferences. To understand people's abilities to express the issues of importance to them within a consultation and clinicians' abilities to acknowledge and address those issues. A qualitative study using an interpretive phenomenological approach. Fifteen people and their physiotherapists were interviewed and their consultations recorded. The resulting data sets were analysed to identify and report themes within the data. The findings revealed that people present with what are often simple issues, but which are sometimes expressed in an unstructured way in clinical encounters and are often difficult for clinicians to establish. Three linked themes emerged: (1) clear versus unstructured agendas; (2) people need information and understanding; and (3) developing a sense of collaboration. The issues of importance that people bring to a consultation are varied and often vague. This research highlights the importance of communication to elicit, identify and address the issues of importance to people in clinical encounters to ensure a positive experience and outcome for both the individual person and clinician. Achieving desirable health outcomes is more likely when people are supported to think about their priorities and 'what matters to them'. Copyright © 2018 Elsevier Ltd. All rights reserved.

Psychosocial and Mental Health Problems of Older People in Postearthquake Nepal.
Adhikari, Ramesh P; Upadhaya, Nawaraj; Paudel, Sasmita; Pokhrel, Ruja; Bhandari, Nagendra; Cole, Laura; Koirala, Suraj
2017-03-01
To identify community perceptions on psychosocial and mental health problems of older people in postearthquake situation in Nepal. A qualitative methodology was adopted to explore the experience and opinions of older people, social workers, school teachers, health workers, and nongovernmental organization workers on the psychosocial and mental health problems of older people in Nepal, using key informant interviews. Major local vocabulary for older peoples' psychosocial and mental health problems were "bichalan" (variation in mood and feeling), "ekohoro" (becoming single minded), "athmabiswasko kami" (low self-esteem), and "bina karan rune" (crying without any reason). The major causes attributed to older people's problems were physical injury, disability, family conflict, and economic problems. Forgetfulness, tiredness, loss of concentration, restlessness, and isolation were observed in older people since the 2015 earthquake. The findings suggest that earthquake had negative impact on older people's psychosocial well-being; however, little support or treatment options have been made available to these individuals. The tailor-made community-based psychosocial and mental health programs for older people are needed.

A dominant EV71-specific CD4+ T cell epitope is highly conserved among human enteroviruses.
Directory of Open Access Journals (Sweden)
Ruicheng Wei
Full Text Available CD4+ T cell-mediated immunity plays a central role in determining the immunopathogenesis of viral infections. However, the role of CD4+ T cells in EV71 infection, which causes hand, foot and mouth disease (HFMD, has yet to be elucidated. We applied a sophisticated method to identify promiscuous CD4+ T cell epitopes contained within the sequence of the EV71 polyprotein. Fifteen epitopes were identified, and three of them are dominant ones. The most dominant epitope is highly conserved among enterovirus species, including HFMD-related coxsackieviruses, HFMD-unrelated echoviruses and polioviruses. Furthermore, the CD4+ T cells specific to the epitope indeed cross-reacted with the homolog of poliovirus 3 Sabin. Our findings imply that CD4+ T cell responses to poliovirus following vaccination, or to other enteroviruses to which individuals may be exposed in early childhood, may have a modulating effect on subsequent CD4+ T cell response to EV71 infection or vaccine.

Autosomal dominant cortical tremor, myoclonus and epilepsy.
Striano, Pasquale; Zara, Federico
2016-09-01
The term 'cortical tremor' was first introduced by Ikeda and colleagues to indicate a postural and action-induced shivering movement of the hands which mimics essential tremor, but presents with the electrophysiological findings of cortical reflex myoclonus. The association between autosomal dominant cortical tremor, myoclonus and epilepsy (ADCME) was first recognized in Japanese families and is now increasingly reported worldwide, although it is described using different acronyms (BAFME, FAME, FEME, FCTE and others). The disease usually takes a benign course, although drug-resistant focal seizures or slight intellectual disability occur in some cases. Moreover, a worsening of cortical tremor and myoclonus is common in advanced age. Although not yet recognized by the International League Against Epilepsy (ILAE), this is a well-delineated epilepsy syndrome with remarkable features that clearly distinguishes it from other myoclonus epilepsies. Moreover, genetic studies of these families show heterogeneity and different susceptible chromosomal loci have been identified.

Should people with unhealthy lifestyles pay higher health insurance premiums?
Buchanan, David R
2011-02-01
This commentary sets the article by Dubois on the ethical justification for charging higher insurance premiums for people with unhealthy lifestyles in the context of US health care reform. It reviews the relevance and strength of normative concerns identified by Dubois about the acceptability of such differentiated "means-tested" plans. It identifies key issues involving whether certain health behaviors matter ethically, and if so, the grounds that would justify an obligation for people to take action. The article frames the answer in terms of the need to achieve an ethically acceptable balance between the principle of equality and principle of merit and concludes with four ethical standards to focus the terms of the debate.

Self-Blame and Commodification of Unemployed Young People
DEFF Research Database (Denmark)
Pultz, Sabina
Young people face the risk of unemployment in a labor market characterized by a drift towards precarious employment (Kalleberg, 2013). Building on poststructuralist theory this study documents how young unemployed people’s understanding of unemployment is affected by neoliberal discourses, also...... reflected in the technologies applied by the institutions in the employment area. As a result, responsibility for unemployment is increasingly placed on the individual and self-blame is promoted as the predominant explanation. This qualitative study consists of a combination of field observations made...... people experience their situation and position themselves in regards to this normative encouragement to blame themselves. Personal branding and networking are identified as strategies enforced by the employment system and can be viewed as technologies of the self encouraging young people to commodify...

Modelling complex social behavior in the laboratory is challenging and requires analyses of dyadic interactions occurring over time in a physically and socially complex environment. In the current study, we approached the analyses of complex social interactions in group-housed male CD1 mice living in a large vivarium. Intensive observations of social interactions during a 3-week period indicated that male mice form a highly linear and steep dominance hierarchy that is maintained by fighting and chasing behaviors. Individual animals were classified as dominant, sub-dominant or subordinate according to their David’s Scores and I& SI ranking. Using a novel dynamic temporal Glicko rating method, we ascertained that the dominance hierarchy was stable across time. Using social network analyses, we characterized the behavior of individuals within 66 unique relationships in the social group. We identified two individual network metrics, Kleinberg’s Hub Centrality and Bonacich’s Power Centrality, as accurate predictors of individual dominance and power. Comparing across behaviors, we establish that agonistic, grooming and sniffing social networks possess their own distinctive characteristics in terms of density, average path length, reciprocity out-degree centralization and out-closeness centralization. Though grooming ties between individuals were largely independent of other social networks, sniffing relationships were highly predictive of the directionality of agonistic relationships. Individual variation in dominance status was associated with brain gene expression, with more dominant individuals having higher levels of corticotropin releasing factor mRNA in the medial and central nuclei of the amygdala and the medial preoptic area of the hypothalamus, as well as higher levels of hippocampal glucocorticoid receptor and brain-derived neurotrophic factor mRNA.

People with severe mental illnesses die early from cardiovascular disease. Evidence is lacking regarding effective primary care based interventions to tackle this problem. To identify current procedures for, barriers to, and facilitators of the delivery of primary care based interventions for lowering cardiovascular risk for people with severe mental illnesses. 75 GPs, practice nurses, service users, community mental health staff and carers in UK GP practice or community mental health settings were interviewed in 14 focus groups which were audio-recorded, transcribed and analysed using Framework Analysis. Five barriers to delivering primary care based interventions for lowering cardiovascular risk in people with severe mental illnesses were identified by the groups: negative perceptions of people with severe mental illnesses amongst some health professionals, difficulties accessing GP and community-based services, difficulties in managing a healthy lifestyle, not attending appointments, and a lack of awareness of increased cardiovascular risk in people with severe mental illnesses by some health professionals. Identified facilitators included involving supportive others, improving patient engagement with services, continuity of care, providing positive feedback in consultations and goal setting. We identified a range of factors which can be incorporated in to the design, delivery and evaluation of services to reduce cardiovascular risk for people with severe mental illnesses in primary care. The next step is determining the clinical and cost effectiveness of primary care based interventions for lowering cardiovascular risk in people with severe mental illnesses, and evaluating the most important components of such interventions.

Complex health service needs for people who are homeless.
Moore, Gaye; Manias, Elizabeth; Gerdtz, Marie Frances
2011-11-01
Homeless people face many challenges in accessing and utilising health services to obtain psychosocial supports offered in hospital and community settings. The complex nature of health issues is compounded by lack of accessibility to services and lack of appropriate and safe housing. To examine the perceptions and experiences of homeless people in relation to their health service needs as well as those of service providers involved with their care. A purposive sampling approach was undertaken with a thematic framework analysis of semi-structured interviews. Participants. Interviews were undertaken with 20 homeless people who accessed the emergency department in an acute hospital in Melbourne, Australia and 27 service providers involved in hospital and community care. Six key themes were identified from interviews: complexity of care needs, respect for homeless people and co-workers, engagement as a key strategy in continued care, lack of after-hour services, lack of appropriate accommodation and complexity of services. Findings revealed the complex and diverse nature of health concerns in homeless people. The demand on hospital services continues to increase and unless government policies take into consideration the psychosocial demands of the communities most vulnerable people efforts to divert hospital demand will continue to fail.

Children and young people's perceptions of energy drinks: A qualitative study.
Visram, Shelina; Crossley, Stephen J; Cheetham, Mandy; Lake, Amelia
2017-01-01
Consumption of soft drinks is declining in many countries, yet energy drink sales continue to increase, particularly amongst young consumers. Little is currently known about the drivers behind these trends. Energy drinks are high in sugar and caffeine, and evidence indicates that regular or heavy use by under 18s is likely to be detrimental to health. This study aimed to explore children and young people's attitudes and perceptions in relation to energy drinks in a UK context. Eight focus groups were conducted with pupils aged 10-11 years (n = 20) and 13-14 years (n = 17) from four schools in northern England. A sub-sample also took part in a mapping exercise to generate further insights. Data were analysed using the constant comparative approach. Energy drinks were reportedly consumed in a variety of public and private places, generally linked to social activities, sports and computer gaming (particularly amongst boys). Participants demonstrated strong brand awareness and preferences that were linked to taste and perceived value for money. The relatively low price of energy drinks and their widespread availability were identified as key factors, along with gendered branding and marketing. Some participants demonstrated a critical approach to manufacturers' claims and many were keen to become better informed, often through school- or peer-based interventions. Other potential interventions included age restrictions, voluntary schemes involving retailers and improved labelling. The lack of a single dominant factor in participants' consumption choices suggests that there is unlikely to be a 'silver bullet' in attempting to address this issue. However, the findings provide support for policy-level interventions that seek to change the behaviours of manufacturers and retailers as well as consumers, and actively involve children and young people where possible.

Evidence of multisensory plasticity: Asymmetrical medial geniculate body in people with one eye
Directory of Open Access Journals (Sweden)
Stefania S. Moro
2015-01-01
Conclusions: volume asymmetry in the MGB in people with one eye may represent increased interactions between the left MGB and primary auditory cortex. This interaction could contribute to increased auditory and other left hemisphere-dominant processing, including language, as compensation for the loss of one half of visual inputs early in life. The positive correlation between MGB and LGN volume is not due to space constraints but rather indicates increased plasticity in both auditory and visual sensory systems following early eye enucleation.

Almost stochastic dominance for poverty level in Central Java Province
Slamet, Isnandar; Agus Wibowo, Aryanto; Roswitha, Mania
2017-12-01
The criteria for the domination of the distribution function has been used in the investment issues, momentum, agricultural production, and so on. One criteria of domination is stochastic dominance (SD). When this criteria is applied to the dominating area that has smaller value than the dominated area, then almost stochastic dominance (ASD) can be used. It this research, we apply the ASD criteria on data of expenditure per capita based on districts/cities in Central Java. Furthermore, we determine which year the expenditure per capita in the period 2009-2013 is the most dominating to know the level of poverty in Central Java. From the discussion, it can be concluded that the expenditure per capita in Central Java in 2013 dominates expenditure per capita in Central Java in 2009-2012. In other words, the level of poverty in Central Java in 2013 is lower than in 2009-2012.

Because eating habits are inseparably linked with people's physical health, effective behaviour interventions are highly demanded to promote healthy eating among older people. The aim of this systematic review was to identify effective diet interventions for older people and provide useful evidence and direction for further research. Three electronic bibliographic databases-PubMed, Scopus and Web of Science Core Collection were used to conduct a systematic literature search based on fixed inclusion and exclusion criteria. English language peer-reviewed journal articles published between 2011 and 2016 were selected for data extraction and quality assessment. Finally, a total of 16 studies were identified. The studies' duration ranged from three weeks to seven years. The majority of studies were carried out in European countries. Seven studies had a moderate quality while the remaining studies were at a less than moderate level. Three dietary educational interventions and all meal service related interventions reported improvements in older people's dietary variety, nutrition status, or other health-related eating behaviours. Multicomponent dietary interventions mainly contributed to the reduction of risk of chronic disease. The results supported that older people could achieve a better dietary quality if they make diet-related changes by receiving either dietary education or healthier meal service. Further high-quality studies are required to promote healthy eating among older people by taking regional diet patterns, advanced information technology, and nudging strategies into account.

2010-01-01
We present a case of right hemispheric dominance for sign language but left hemispheric dominance for reading, in a left-handed deaf patient with epilepsy and left mesial temporal sclerosis. Atypical language laterality for ASL was determined by preoperative fMRI, and congruent with ASL modified WADA testing. We conclude that reading and sign language can have crossed dominance and preoperative fMRI evaluation of deaf patients should include both reading and sign language evaluations.

The Lower Mekong River basin, including Tonle Sap Lake (TSL), is the largest inland fishery in the world and a dominant source of protein and income for much of Southeast Asia. Maintaining ecosystem productivity in the face of large-scale environmental change from hydroelectric dams and climate change is critical for economic and social well-being in the region. Yet, we currently lack the most basic understanding of how hydrologic variation relates to fisheries production, nutritional quality, and ultimately livelihoods of people. We will describe past, present, and future research to establish mechanistic connections between the hydrology, ecology, and sustainability of the Mekong ecosystem. Past research includes application of a state-space oxygen mass balance model and continuous dissolved oxygen measurements from four locations to provide the first estimates of gross primary productivity (GPP) and ecosystem respiration (ER) for the Tonle Sap. GPP averaged 4.1 × 2.3 g O2 m-3 d-1 with minimal differences among sites, while ER averaged 24.9 × 20.0 g O2 m-3 d-1, but had greater than six-fold variation among sites. Using our measurements of GPP, we calibrated a hydrodynamic-productivity model and predicted aquatic net primary production of 2.0 × 0.2 g C m-2 d-1 (2.4 × 0.2 million tonnes C y-1). Present research is using stable isotope and fatty acid methyl ester biomarkers to investigate basal carbon sources to the fishery, focusing specifically on the role of biogenic methane oxidation in supporting the food web. Individuals a wide variety of taxa had tissue carbon isotope values (δ13C) ranging from -36 to -57 per mil. These extremely depleted values are best explained by utilization of biogenic methane by methane oxidizing bacteria (MOB) and subsequent grazing of these bacterial by benthic insects and ultimately fishes. The presence of MOB in the food web was confirmed by identifying 16:1ω8 and 18:1ω8 FAME biomarkers specific to these bacteria in fish

To assess the role that social contextual factors exert on the way people with disproportionate short stature (dwarfism) cope with the negative consequences of discrimination. Using multigroup structural equation modeling, we compare the coping process of people with dwarfism from Spain (N = 63) and the USA (N = 145), two countries that differ in the role played by organizations offering support to people with dwarfism. In Spain, where organizational support is recent, a coping approach aimed at achieving integration with the majority group through limb-lengthening surgery prevails; in the USA, where the long-standing organization of people with dwarfism encourages pride in being a "little person" and positive intragroup contact, a coping strategy based on empowering the minority group dominates. Both strategies, each in its own context, are effective at protecting psychological well-being from the negative consequences of stigmatization; however, they exert their positive effects through different processes.

Radiation-induced dominant skeletal mutations in mice
International Nuclear Information System (INIS)
Selby, P.B.
1979-01-01
Skeletons were chosen for the attempt to determine the overall damage by radiation to one body system largely bacause they can be prepared readily for detailed study. Dominant mutations were of special interest because they are the type of mutations that would account for almost all damage induced in the early generations. The male offsprings derived from spermatogonial irradiation were used in the mutation-rate experiment, and the mutation frequency of 1.4% per gamete was found. The general dominant skeletal mutations are 1) the fusions of bones or other changes in individual bones, 2) the gross changes in bone shapes, usually caused by incomplete or too extensive bone growth, or 3) the shifts in the relative positions of bones. The recessive lethality in the period between implantation and birth can be recognized by the expected high death rate of implants in approximately 1/4 of the crosses that are between heterozygotes for a given mutation. The recessive lethal mutations may account for an important fraction of human genetic disorders owing to their dominant deleterious effects which represent only a small fraction, but because of their easy detection, they have been studied more than other dominants. At least 45, or 27%, of 164 dominant visibles in mice, ignoring those concerned with enzyme polymorphisms and immunological traits, appear to be recessive lethals. (Yamashita, S.)

Full Text Available Research investigating the psychological difficulties experienced by people with Parkinson's disease (PD is dominated by individualistic neurobiological and psychological perspectives. Therefore, this opinion paper draws on a reformulation of the social model of disability, Thomas' (1999 and (2007 social relational approach to disablism, to offer an alternative way of conceptualising psychological difficulties experienced by people with PD. This opinion paper explores the ways in which socially imposed restrictions and stigma may contribute to psychological difficulties by using Thomas' (2007 concept of psychoemotional disablism. By using the lens of psychoemotional disablism, this paper demonstrates that people with PD can be exposed to stigmatising attitudes and interactions which could contribute to restrictions, feelings of shame, and psychological difficulties such as depression. Accordingly, it is argued that further attention to the link between psychological difficulties and social dimensions of disablism in PD is needed in both research arenas and clinical practice to broaden understandings and interventions for people with PD.

Behavioral and social cognitive processes in preschool children's social dominance.
Pellegrini, Anthony D; Van Ryzin, Mark J; Roseth, Cary; Bohn-Gettler, Catherine; Dupuis, Danielle; Hickey, Meghan; Peshkam, Annie
2011-01-01
This longitudinal, naturalistic study addressed behavioral and social cognitive processes implicated in preschool children's social dominance. In the first objective, we examined the degree to which peer aggression, affiliation, and postaggression reconciliation predicted social dominance across a school year. Consistent with predictions, all three predicted dominance early in the year while only affiliation predicted dominance later in the year, suggesting that aggression, affiliation, and reconciliation were used to establish social dominance where affiliation was used to maintain it. In the second, exploratory, objective we tested the relative importance of social dominance and reconciliation (the Machiavellian and Vygotskian intelligence hypotheses, respectively) in predicting theory of mind/false belief. Results indicated that social dominance accounted for significant variance, beyond that related to reconciliation and affiliation, in predicting theory of mind/false belief status. Results are discussed in terms of specific behavioral and social cognitive processes employed in establishing and maintaining social dominance. © 2011 Wiley-Liss, Inc.

Impact of social media on the health of children and young people.
Richards, Deborah; Caldwell, Patrina H Y; Go, Henry
2015-12-01
This paper reviews the literature on the impact of social media on the health of children and young people. Relevant papers were identified from Medline, Embase and PsycINFO databases. The studies identified that the health impact of social media on children and young people was greatest on mental health and specifically in the areas of self-esteem and well-being, with related issues around cyberbullying and 'Facebook Depression', with an association between the use of social media and self-esteem and body image. However, it is difficult to determine the cause and effect, which is likely to be related to the nature of the young person. There is little work on the impact of social media on younger children. More research is needed to identify those most at risk of harm from social media and risk mitigation strategies to assist health-care professionals to provide essential education for parents and young people. © 2015 The Authors.

Recent studies propose two theories explaining the particular mechanisms of mate choice. Theory of homogamy suggests that individuals prefer partners with personality traits similar to their own. In contrast, theory of complementarity states that people choose mates with opposite personality traits. The main aims of this study were i) to test homogamy and complementarity of dominance in long-term heterosexual and homosexual male couples and ii) to examine whether this similarity predicts high...

Regular participation in resistance training is important for older people to maintain their health and independence, yet participation rates are low. The study aimed to identify motivators and barriers to older people participating in resistance training. A systematic review was conducted including quantitative, qualitative, and mixed-method studies. Searches generated 15,920 citations from six databases, with 14 studies (n = 1,937 participants) included. In total, 92 motivators and 24 barriers were identified. Motivators specific to participating in resistance training included preventing deterioration (disability), reducing risk of falls, building (toning) muscles, feeling more alert, and better concentration. Looking too muscular and thinking participation increased the risk of having a heart attack, stroke, or death, despite the minimal likelihood of these occurring, were barriers. The analysis indicates that increasing participation in resistance training among older people should focus on the specific benefits valued by older people and the dissemination of accurate information to counter misperceptions.

Over the years neoliberal ideology and discourse have become intricately connected to making science people. Science educators work within a complicated paradox where they are obligated to meet neoliberal demands that reinscribe dominant, hegemonic assumptions for producing a scientific workforce. Whether it is the discourse of school science, processes of being a scientist, or definitions of science particular subjects are made intelligible as others are made unintelligible. This paper resides within the messy entanglements of feminist poststructural and new materialist perspectives to provoke spaces where science educators might enact ethicopolitical hesitations. By turning to and living in theory, the un/making of certain kinds of science people reveals material effects and affects. Practicing ethicopolitical hesitations prompt science educators to consider beginning their work from ontological assumptions that begin with abundance rather than lack.

Adults with intellectual disability experience substantial health inequities. Public health research aiming to improve the lives of this population group is needed. We sought to investigate the extent to which a sample of international public health research includes and identifies people with intellectual disability. In this systematic review, we examined a select number of public health journals to determine (1) how often people with intellectual disability are explicitly included in randomised controlled trials (RCTs) and cohort studies and (2) how the presence of intellectual disability is identified and reported. Among eligible articles in these selected public health journals, it was found that cohort studies passively exclude people with intellectual disability, while RCTs actively exclude this population. Most general population articles that explicitly identified people with intellectual disability did so through self-report or proxy report and databases. A more extensive and adequate evidence base relating to the health of this overlooked population group is needed. A useful first step would be for researchers specialising in intellectual disability to identify how we can best assist mainstream researchers to include and identify people with intellectual disability in their population-level studies. © Royal Society for Public Health 2014.

Academic literature analyzing the Bureau of Land Management (BLM) land-use subgovernment stops at the Taylor Grazing Act and concludes that the historical development of administering grazing on public lands led to the capture of the BLM by ranching interests. Using a two-pronged methodological approach of process tracing and elite interviews this dissertation seeks to advance our collective knowledge of subgovernment theory by (a) clarifying the impact executive decision-making has on subgovernments and (b) identifying the conditions under which strategically competitive behavior between two competing subgovernment actors occurs. The dissertation seeks to update the literature by explaining what has caused the BLM to shift from a rancher-dominated agency to an energy dominated agency by identifying conditions under which subgovernment actors strategically respond to a political conflict. The research poses two questions: (1) how have executive actions disrupted an existing balance of power in a so-called "strong corner" of an entrenched subgovernment system and (2) what happens when conflict and competition break out between allied members of the system? Analysis indicates that as the BLM responded to Executive actions emphasizing domestic energy production, a conflict emerged between traditional allies: ranching and energy. Triggered by the unintended consequence of awakening long-dormant legislation, split-estate energy development---where property rights are severed between private surface and federal mineral estates---expanded across the West. In turn, this expansion helped establish the conditions for conflict and in doing so disrupted the balance of power between large public resource use interests in the relatively stable land-use subgovernment of the BLM. Indicative of energy's emerging dominance of the BLM's subgovernment, split-estate energy development led ranching interests to seek the protection of their Western state legislatures. This shift in

Behavioral Profile Predicts Dominance Status in Mountain Chickadees.
Fox, Rebecca A; Ladage, Lara D; Roth, Timothy C; Pravosudov, Vladimir V
2009-06-01
Individual variation in stable behavioral traits may explain variation in ecologically-relevant behaviors such as foraging, dispersal, anti-predator behavior, and dominance. We investigated behavioral variation in mountain chickadees (Poecile gambeli), a North American parid that lives in dominance-structured winter flocks, using two common measures of behavioral profile: exploration of a novel room and novel object exploration. We related those behavioral traits to dominance status in male chickadees following brief, pair-wise encounters. Low-exploring birds (birds that visited less than four locations in the novel room) were significantly more likely to become dominant in brief, pairwise encounters with high-exploring birds (i.e., birds that visited all perching locations within a novel room). On the other hand, there was no relationship between novel object exploration and dominance. Interestingly, novel room exploration was also not correlated with novel object exploration. These results suggest that behavioral profile may predict the social status of group-living individuals. Moreover, our results contradict the idea that novel object exploration and novel room exploration are always interchangeable measures of individuals' sensitivity to environmental novelty.

Hypothalamic digoxin, hemispheric chemical dominance, and peptic ulcer disease.
Kurup, Ravi Kumar; Kurup, Parameswara Achutha
2003-10-01
The isoprenoid pathway produces three key metabolites--endogenous digoxin-like factor (EDLF) (membrane sodium-potassium ATPase inhibitor and regulator of neurotransmitter transport), ubiquinone (free radical scavenger), and dolichol (regulator of glycoconjugate metabolism). The pathway was assessed in peptic ulcer and acid peptic disease and its relation to hemispheric dominance studied. The activity of HMG CoA reductase, serum levels of EDLF, magnesium, tryptophan catabolites, and tyrosine catabolites were measured in acid peptic disease, right hemispheric dominant, left hemispheric dominant, and bihemispheric dominant individuals. All the patients with peptic ulcer disease were right-handed/left hemispheric dominant by the dichotic listening test. The pathway was upregulated with increased EDLF synthesis in peptic ulcer disease (PUD). There was increase in tryptophan catabolites and reduction in tyrosine catabolites in these patients. The ubiquinone levels were low and free radical production increased. Dolichol and glycoconjugate levels were increased and lysosomal stability reduced in patients with acid peptic disease (APD). There was increase in cholesterol:phospholipid ratio with decreased glyco conjugate levels in membranes of patients with PUD. Acid peptic disease represents an elevated EDLF state which can modulate gastric acid secretion and the structure of the gastric mucous barrier. It can also lead to persistence of Helicobacter pylori infection. The biochemical pattern obtained in peptic ulcer disease is similar to those obtained in left-handed/right hemispheric chemically dominant individuals. But all the patients with peptic ulcer disease were right-handed/left hemispheric dominant by the dichotic listen ing test. Hemispheric chemical dominance has no correlation with handedness or the dichotic listening test. Peptic ulcer disease occurs in right hemispheric chemically dominant individuals and is a reflection of altered brain function.

Photosynthesis in Hydrogen-Dominated Atmospheres
Bains, William; Seager, Sara; Zsom, Andras
2014-01-01
The diversity of extrasolar planets discovered in the last decade shows that we should not be constrained to look for life in environments similar to early or present-day Earth. Super-Earth exoplanets are being discovered with increasing frequency, and some will be able to retain a stable, hydrogen-dominated atmosphere. We explore the possibilities for photosynthesis on a rocky planet with a thin H2-dominated atmosphere. If a rocky, H2-dominated planet harbors life, then that life is likely to convert atmospheric carbon into methane. Outgassing may also build an atmosphere in which methane is the principal carbon species. We describe the possible chemical routes for photosynthesis starting from methane and show that less energy and lower energy photons could drive CH4-based photosynthesis as compared with CO2-based photosynthesis. We find that a by-product biosignature gas is likely to be H2, which is not distinct from the hydrogen already present in the environment. Ammonia is a potential biosignature gas of hydrogenic photosynthesis that is unlikely to be generated abiologically. We suggest that the evolution of methane-based photosynthesis is at least as likely as the evolution of anoxygenic photosynthesis on Earth and may support the evolution of complex life. PMID:25411926

The aim of the current study was to create a typology of patients with first-episode psychosis based on sociodemographic and clinical characteristics, service use and outcomes using cluster analysis. Data from all respondents who were accepted into the Early Psychosis Intervention Programme (EPIP), Singapore from 2007 to 2011 were analysed. A two-step clustering method was carried out to classify the patients into distinct clusters. Two clusters were identified. Cluster 1 comprised largely of younger people with mean age of 25.5 (6.0) years at treatment contact, who were predominantly male (55.3%), single (98.3%) and living with parents (86.3%). Cluster 1 had a higher proportion of people diagnosed with the schizophrenia spectrum disorder (71.4%) and with a positive family history of psychiatric illness. Patients in cluster 2 were generally older with a mean age of 33.6 (4.7) years and the majority were women (74.2%). Cluster 1 had people with higher Positive and Negative Syndrome Scale (PANSS) scores at baseline as compared with cluster 2. After a 1-year follow up, their scores were still poorer than their counterparts in cluster 2, especially for PANSS negative score. The functioning level of people in cluster 1 showed less improvement than the people in cluster 2 after a year of treatment. There is a compelling need to develop new therapies and intensively treat young people presenting with psychosis as this group tends to have poorer outcomes even after 1 year of treatment. © 2014 Wiley Publishing Asia Pty Ltd.

Genomic Analysis and Surveillance of the Coronavirus Dominant in Ducks in China.
Directory of Open Access Journals (Sweden)
Qing-Ye Zhuang
Full Text Available The genetic diversity, evolution, distribution, and taxonomy of some coronaviruses dominant in birds other than chickens remain enigmatic. In this study we sequenced the genome of a newly identified coronavirus dominant in ducks (DdCoV, and performed a large-scale surveillance of coronaviruses in chickens and ducks using a conserved RT-PCR assay. The viral genome harbors a tandem repeat which is rare in vertebrate RNA viruses. The repeat is homologous to some proteins of various cellular organisms, but its origin remains unknown. Many substitutions, insertions, deletions, and some frameshifts and recombination events have occurred in the genome of the DdCoV, as compared with the coronavirus dominant in chickens (CdCoV. The distances between DdCoV and CdCoV are large enough to separate them into different species within the genus Gammacoronavirus. Our surveillance demonstrated that DdCoVs and CdCoVs belong to different lineages and occupy different ecological niches, further supporting that they should be classified into different species. Our surveillance also demonstrated that DdCoVs and CdCoVs are prevalent in live poultry markets in some regions of China. In conclusion, this study shed novel insight into the genetic diversity, evolution, distribution, and taxonomy of the coronaviruses circulating in chickens and ducks.

An overall approach to health care for indigenous peoples.
King, Malcolm
2009-12-01
Indigenous peoples across all the continents of the globe live with major gaps in health status and health outcomes associated with well-described social determinants of health, such as poverty and poor education. Indigenous peoples face additional health determinant issues associated with urbanization, isolation from traditional territories, and loss of cultural continuity. Indigenous children are particularly vulnerable as they grow up in isolation from their cultural and social roots and yet are also separated from the mainstream environment of their society. Programs to address these difficult health issues should be viewed as complex clinical interventions with health researchers, social scientists, and clinicians working together with Indigenous peoples to identify the most pressing needs and most appropriate and workable solutions that will result in effective policies and practices.

Iron is the fourth most abundant element in the Earth's crust and is potentially one of the most abundant energy sources on the earth as an electron donor for chemolithoautotrophic growth coupled to Fe(II) oxidation. Despite the rapid abiotic oxidation rate of iron, many microbes have adapted to feeding off this fleeting energy source. One such bacterial class is the Zetaproteobacteria. Iron-dominated microbial mat material was collected with a small-scale syringe sampler from Loihi Seamount, Hawaii. From this sample, gDNA was extracted and prepared for paired-end Illumina sequencing. Reconstruction of SSU rDNA genes using EMERGE allowed for comparison to previous SSU rDNA surveys. Clone libraries and qPCR show these microbial mats to be dominated by Zetaproteobacteria. Results from our in silico reconstruction confirm these initial findings. RDP classification of the EMERGE reconstructed sequences resulted in 44% of the community being identified as Zetaproteobacteria. The most abundant SSU rDNA has 99% similarity to Zeta OTU-2, and only a 94% similarity to M. ferrooxidans PV-1. Zeta OTU-2 has been shown to be the most cosmopolitan population in iron-dominated hydrothermal systems from across Pacific Ocean. Metagenomic assembly has resulted in many contigs with high identity to M. ferrooxidans as identified, by BLAST. However, with large differences in SSU rRNA similarity, M. ferrooxidans PV-1 is not an adequate reference. Current work is focusing on reconstruction of the dominant microbial mat member, without the use of a reference genome through an iterative assembly approach. The resulting 'pan-genome' will be compared to other Zetaproteobacteria (at the class level) and the functional ecology of this cosmopolitan microbial mat community member will be extrapolated. Thus far, we have detected multiple housekeeping genes involved in DNA replication, transcription and translation. The most abundant metabolic gene we have found is Aconitase, a key enzyme in the

Information needs of people with asthma.
Kong, Ming Ley; Armour, Carol; LeMay, Kate; Smith, Lorraine
2014-06-01
To describe the information needs of a group of Australians with asthma and the extent to which their needs had been met. A self-administered survey was completed by people with asthma either presenting at community pharmacies or registered with a medical research institute database. The survey questions were developed based on a review of the literature, and included questions regarding participants' information needs about their asthma, their sources of asthma information and the extent to which these information needs had been met. The responses concerning information needs were analysed thematically. Responses concerning sources of asthma information and the extent to which needs were met were analysed using descriptive and correlational statistics. Seventy-one people completed the survey. Key information needs that were identified included medications, management of asthma, asthma triggers, cure, aetiology of asthma and latest research. A third of participants reported having only 'very little', 'a little' or 'some' of their information needs met. The most common source of information was from a doctor (94% respondents), followed by a pharmacist or pharmacy assistant (56%). Insights into the information needs of people with asthma have been provided. In light of the level of unmet information needs of people with asthma, and the types of information sought, pharmacists are in an ideal position to close the information gap and promote optimal asthma self-management practices. © 2013 Royal Pharmaceutical Society.

A Systematic Review of Suicidality in People with Intellectual Disabilities.
Dodd, Philip; Doherty, Ailbhe; Guerin, Suzanne
2016-01-01
Suicidality in people with intellectual disability has not been extensively researched. To identify the nature of the research that has actually been conducted on this topic. A search of research databases was conducted according to predefined criteria. Key information was extracted and rated for methodological merit. Twenty-four studies met the inclusion criteria for this systematic review. The aspects of suicidality investigated, which varied among studies, included suicidal attempts, behavior, ideation, and completed suicide. Thirteen studies highlighted risk factors for suicidality in this population. The most frequently noted risk factors were a concurrent mental health difficulty and the level of intellectual disability. Eight studies referred to people with intellectual disabilities' understanding of the concept of death or suicide. Various methodological issues were identified in the studies included. In what we believe to be first systematic review of suicidality in people with intellectual disabilities, it was apparent that well-designed, standardized research studies on the topic are scarce. There is consequently limited evidence to guide prevention and intervention strategies for suicidality in this population.

Two contrasting views of handedness can be described as 1) complementary dominance, in which each hemisphere is specialized for different aspects of motor control, and 2) global dominance, in which the hemisphere contralateral to the dominant arm is specialized for all aspects of motor control. The present study sought to determine which motor lateralization hypothesis best predicts motor performance during common bilateral task of stabilizing an object (e.g. bread) with one hand while applying forces to the object (e.g. slicing) using the other hand. We designed an experimental equivalent of this task, performed in a virtual environment with the unseen arms supported by frictionless air-sleds. The hands were connected by a spring, and the task was to maintain the position of one hand, while moving the other hand to a target. Thus, the reaching hand was required to take account of the spring load to make smooth and accurate trajectories, while the stabilizer hand was required to impede the spring load to keep a constant position. Right-handed subjects performed two task sessions (right hand reach and left hand stabilize; left hand reach and right hand stabilize) with the order of the sessions counterbalanced between groups. Our results indicate a hand by task-component interaction, such that the right hand showed straighter reaching performance while the left showed more stable holding performance. These findings provide support for the complementary dominance hypothesis and suggest that the specializations of each cerebral hemisphere for impedance and dynamic control mechanisms are expressed during bilateral interactive tasks.

Full Text Available People with severe mental illnesses die early from cardiovascular disease. Evidence is lacking regarding effective primary care based interventions to tackle this problem.To identify current procedures for, barriers to, and facilitators of the delivery of primary care based interventions for lowering cardiovascular risk for people with severe mental illnesses.75 GPs, practice nurses, service users, community mental health staff and carers in UK GP practice or community mental health settings were interviewed in 14 focus groups which were audio-recorded, transcribed and analysed using Framework Analysis.Five barriers to delivering primary care based interventions for lowering cardiovascular risk in people with severe mental illnesses were identified by the groups: negative perceptions of people with severe mental illnesses amongst some health professionals, difficulties accessing GP and community-based services, difficulties in managing a healthy lifestyle, not attending appointments, and a lack of awareness of increased cardiovascular risk in people with severe mental illnesses by some health professionals. Identified facilitators included involving supportive others, improving patient engagement with services, continuity of care, providing positive feedback in consultations and goal setting.We identified a range of factors which can be incorporated in to the design, delivery and evaluation of services to reduce cardiovascular risk for people with severe mental illnesses in primary care. The next step is determining the clinical and cost effectiveness of primary care based interventions for lowering cardiovascular risk in people with severe mental illnesses, and evaluating the most important components of such interventions.

Adolescents with perinatal HIV (PHIV) may be at higher risk of anxiety and depression than HIV negative young people. We investigated prevalence of anxiety and depression symptoms in 283 PHIV and 96 HIV-affected (HIV-negative) young people in England recruited into the Adolescents and Adults Living with Perinatal HIV (AALPHI) cohort. We used Hospital Anxiety and Depression Scale (HADS) scores and linear regression investigated predictors of higher (worse) scores.115 (41%) and 29 (30%) PHIV and HIV-affected young people were male, median age was 16 [interquartile range 15,18] and 16 [14,18] years and 241 (85%) and 71 (74%) were black African, respectively. There were no differences in anxiety and depression scores between PHIV and HIV-affected participants. Predictors of higher anxiety scores were a higher number of carers in childhood, speaking a language other than English at home, lower self-esteem, ever thinking life was not worth living and lower social functioning. Predictors of higher depression scores were male sex, death of one/both parents, school exclusion, lower self-esteem and lower social functioning. In conclusion, HIV status was not associated with anxiety or depression scores, but findings highlight the need to identify and support young people at higher risk of anxiety and depression..

Load estimation from planar PIV measurement in vortex dominated flows
McClure, Jeffrey; Yarusevych, Serhiy
2017-11-01
Control volume-based loading estimates are employed on experimental and synthetic numerical planar Particle Image Velocimetry (PIV) data of a stationary cylinder and a cylinder undergoing one degree-of-freedom (1DOF) Vortex Induced Vibration (VIV). The results reveal the necessity of including out of plane terms, identified from a general formulation of the control volume momentum balance, when evaluating loads from planar measurements in three-dimensional flows. Reynolds stresses from out of plane fluctuations are shown to be significant for both instantaneous and mean force estimates when the control volume encompasses vortex dominated regions. For planar measurement, invoking a divergence-free assumption allows accurate estimation of half the identified terms. Towards evaluating the fidelity of PIV-based loading estimates for obtaining the forcing function unobtrusively in VIV experiments, the accuracy of the control volume-based loading methodology is evaluated using the numerical data with synthetically generated experimental PIV error, and a comparison is made between experimental PIV-based estimates and simultaneous force balance measurements.

In the interest of preventing or postponing dependency on care and assistance for as long as possible, preventive home visits to people aged over 70 years living at home were conducted by registered nurses. Assessment of the functional health of people over 70 years of age and counseling or information carried out based on the identified problem areas and resources. A multidimensional nursing assessment through self-evaluation was applied for 345 people aged over 70 years. The sample of people investigated showed a high level of competence in self-care; however, a large number of functional health impairments could be identified that are reflected in the high requirement for counseling and information. It became evident that recruiting of study participants was difficult and that care by family members was an important resource for people aged over 70 years. From this it was recommended that in the future sustainable advertising efforts should be conducted and special attention needs to be given to counseling and information for family members in preventive home visits.

There is a high prevalence of stress, depression, and burn-out in medical students. Medical students differ widely in personality traits, self-perceptions, and values that may have an impact on their well-being. This study aimed to investigate variability in their personality profiles in relation to their potential for well-being and resilience. Participants were 808 medical students from The University of Queensland. An online questionnaire collected socio-demographics and the Temperament and Character Inventory to assess personality traits. Latent profile analyses identified students' trait profiles. Two distinct personality profiles were identified. Profile 1 ("Resilient") characterized 60% of the sample and was distinguished by low Harm Avoidance combined with very high Persistence, Self-Directedness and Cooperativeness compared to Profile 2 ("Conscientious"). Both Profiles had average levels of Reward Dependence and Novelty Seeking and low levels of Self-Transcendence. Profiles did not differ by age, gender, or country of birth, but rural background students were more likely to have Profile 1. While both Profiles indicate mature and healthy personalities, the combination of traits in Profile 1 is more strongly indicative of well-being and resilience. Finding two distinct profiles of personality highlights the importance of considering combinations of traits and how they may interact with medical students' potential for well-being. Although both profiles of students show healthy personalities, many may lack the resilience to maintain well-being over years of medical training. Programs that develop character and personality self-awareness would enhance their well-being and prepare them to promote the health of their patients.

Xiang, Tao; Christensen, Ole Fredslund; Vitezica, Zulma Gladis; Legarra, Andres
2018-05-09
Dominance genetic effects are rarely included in pedigree-based genetic evaluation. With the availability of single nucleotide polymorphism markers and the development of genomic evaluation, estimates of dominance genetic effects have become feasible using genomic best linear unbiased prediction (GBLUP). Usually, studies involving additive and dominance genetic effects ignore possible relationships between them. It has been often suggested that the magnitude of functional additive and dominance effects at the quantitative trait loci are related, but there is no existing GBLUP-like approach accounting for such correlation. Wellmann and Bennewitz showed two ways of considering directional relationships between additive and dominance effects, which they estimated in a Bayesian framework. However, these relationships cannot be fitted at the level of individuals instead of loci in a mixed model and are not compatible with standard animal or plant breeding software. This comes from a fundamental ambiguity in assigning the reference allele at a given locus. We show that, if there has been selection, assigning the most frequent as the reference allele orients the correlation between functional additive and dominance effects. As a consequence, the most frequent reference allele is expected to have a positive value. We also demonstrate that selection creates negative covariance between genotypic additive and dominance genetic values. For parameter estimation, it is possible to use a combined additive and dominance relationship matrix computed from marker genotypes, and to use standard restricted maximum likelihood (REML) algorithms based on an equivalent model. Through a simulation study, we show that such correlations can easily be estimated by mixed model software and accuracy of prediction for genetic values is slightly improved if such correlations are used in GBLUP. However, a model assuming uncorrelated effects and fitting orthogonal breeding values and dominant

The new caring: financial asset management and older people.
Tilse, Cheryl; Wilson, Jill; Setterlund, Deborah; Rosenman, Linda
2007-10-01
Increasing longevity and the growing proportion of the aged in the population in most countries have served to focus on the question of how governments and older people can finance living, health, and care options in retirement. Prudent management of income and assets is an increasingly complex and important aspect of aging as assets and expectations of self-financing increase. Although many informal caregivers act as asset managers and/or substitute decision-makers for older people, little attention has been paid to this increasingly important aspect of care. This paper summaries key findings of a broad research program exploring family involvement in the management of older people's assets and the practices that constitute good practice as well as financial mismanagement and abuse. It identifies multi-level and multi-strategy responses needed to address the issues raised by the research and outlines an innovative community demonstration project aimed at improving financial management practices in relation to older people's assets.

Full Text Available L M G Steuten1, K M M Lemmens2, A P Nieboer2, H JM Vrijhoef31Maastricht University Medical Centre, School for Care and Public Health Research, Department of Health, Organisation, Policy and Economics, Maastricht, The Netherlands; 2Erasmus University Medical Centre, Institute of Health Policy and Management, Rotterdam, The Netherlands; 3Maastricht University Medical Centre, School for Care and Public Health Research, Department of Integrated Care, Maastricht, The NetherlandsObjective: To review published evidence regarding the cost effectiveness of multi-component COPD programs and to illustrate how potentially cost effective programs can be identified.Methods: Systematic search of Medline and Cochrane databases for evaluations of multi-component disease management or chronic care programs for adults with COPD, describing process, intermediate, and end results of care. Data were independently extracted by two reviewers and descriptively summarized.Results: Twenty articles describing 17 unique COPD programs were included. There is little evidence for significant improvements in process and intermediate outcomes, except for increased provision of patient self-management education and improved disease-specific knowledge. Overall, the COPD programs generate end results equivalent to usual care, but programs containing ≥3 components show lower relative risks for hospitalization. There is limited scope for programs to break-even or save money.Conclusion: Identifying cost effective multi-component COPD programs remains a challenge due to scarce methodologically sound studies that demonstrate significant improvements on process, intermediate and end results of care. Estimations of potential cost effectiveness of specific programs illustrated in this paper can, in the absence of ‘perfect data’, support timely decision-making regarding these programs. Nevertheless, well-designed health economic studies are needed to decrease the current decision

F1 hybrid male sterility is thought to result from interactions between loci on the X chromosome and dominant-acting loci on the autosomes. While X-linked loci that contribute to hybrid male sterility have been precisely localized in many animal taxa, their dominant autosomal interactors have been more difficult to localize precisely and/or have been shown to be of relatively smaller effect. Here, we identified and mapped at least four dominant autosomal factors contributing to hybrid male st...

Faces automatically draw attention, allowing rapid assessments of personality and likely behaviour. How we respond to people is, however, highly dependent on whether we know who they are. According to face processing models person knowledge comes from an extended neural system that includes structures linked to episodic memory. Here we use scalp recorded brain signals to demonstrate the specific role of episodic memory processes during face processing. In two experiments we recorded Event-Rel...

No previous published research has examined the applicability of varying methods for identifying young people who are at high risk of experiencing unintended pregnancy and acquiring HIV infection. This study compares three surveys of young people aged 15-24 in Port-au-Prince, Haiti, in terms of their sociodemographic characteristics and sexual behaviors and the surveys'usefulness for identifying young people at high risk and for program planning. The surveys consist of responses from: a representative sample of young people in the 2005-06 Haiti Demographic and Health Survey (HDHS), a 2004 facility-based study, and a 2006-07 venue-based study that used the Priorities for Local AIDS Control Efforts (PLACE) method. The facility-based and PLACE studies included larger proportions of single, sexually experienced young people and people who knew someone with HIV/ AIDS than did the HDHS. More respondents in the PLACE sample had multiple sex partners in the past year and received money or gifts in return for sex, compared with respondents in the facility study. At first and last sex, more PLACE respondents used contraceptives, including condoms. Experience of pregnancy was most commonly reported in the data from the facility-based sample; however, more ever-pregnant PLACE respondents than others reported ever having terminated a pregnancy. Program managers seeking to implement prevention activities should consider using facility- or venue-based methods to identify and understand the behaviors of young people at high risk.

Hypothalamic digoxin, hemispheric chemical dominance, and interstitial lung disease.
Kurup, Ravi Kumar; Kurup, Parameswara Achutha
2003-10-01
The isoprenoid pathway produces three key metabolites--endogenous digoxin, dolichol, and ubiquinone. This was assessed in patients with idiopathic pulmonary fibrosis and in individuals of differing hemispheric dominance to find out the role of hemispheric dominance in the pathogenesis of idiopathic pulmonary fibrosis. All 15 cases of interstitial lung disease were right-handed/left hemispheric dominant by the dichotic listening test. The isoprenoidal metabolites--digoxin, dolichol, and ubiquinone, RBC membrane Na(+)-K+ ATPase activity, serum magnesium, tyrosine/tryptophan catabolic patterns, free radical metabolism, glycoconjugate metabolism, and RBC membrane composition--were assessed in idiopathic pulmonary fibrosis as well as in individuals with differing hemispheric dominance. In patients with idiopathic pulmonary fibrosis there was elevated digoxin synthesis, increased dolichol and glycoconjugate levels, and low ubiquinone and elevated free radical levels. There was also an increase in tryptophan catabolites and a reduction in tyrosine catabolites. There was an increase in cholesterol phospholipid ratio and a reduction in glycoconjugate level of RBC membrane in patients with idiopathic pulmonary fibrosis. Isoprenoid pathway dysfunction con tributes to the pathogenesis of idiopathic pulmonary fibrosis. The biochemical patterns obtained in interstitial lung disease are similar to those obtained in left-handed/right hemispheric chemically dominant individuals by the dichotic listening test. However, all the patients with interstitial lung disease were right-handed/left hemispheric dominant by the dichotic listening test. Hemispheric chemical dominance has no correlation with handedness or the dichotic listening test. Interstitial lung disease occurs in right hemispheric chemically dominant individuals and is a reflection of altered brain function.

Nutritional strategies to reduce falls risk in older people.
Nash, Louise; Bergin, Nick
2018-03-23
A literature review found an association between increased falls risk and malnutrition, sarcopenia, vitamin D deficiency and dehydration. Strategies to identify, prevent and treat these conditions can help to reduce falls risk in at-risk groups such as frail, older people. Nurses can reduce falls risk in older people by raising awareness of risk factors and embedding nutritional strategies in local falls reduction strategies. ©2018 RCN Publishing Company Ltd.

The Vulnerability of Some Networks including Cycles via Domination Parameters
Directory of Open Access Journals (Sweden)
Tufan Turaci
2016-01-01
Full Text Available Let G=(V(G,E(G be an undirected simple connected graph. A network is usually represented by an undirected simple graph where vertices represent processors and edges represent links between processors. Finding the vulnerability values of communication networks modeled by graphs is important for network designers. The vulnerability value of a communication network shows the resistance of the network after the disruption of some centers or connection lines until a communication breakdown. The domination number and its variations are the most important vulnerability parameters for network vulnerability. Some variations of domination numbers are the 2-domination number, the bondage number, the reinforcement number, the average lower domination number, the average lower 2-domination number, and so forth. In this paper, we study the vulnerability of cycles and related graphs, namely, fans, k-pyramids, and n-gon books, via domination parameters. Then, exact solutions of the domination parameters are obtained for the above-mentioned graphs.

Reactions of teachers versus non-teachers toward people who stutter.
Li, Jian; Arnold, Hayley S
2015-01-01
The primary purpose of this study was to assess whether kindergarten through twelfth grade teachers differ from people in non-teaching occupations in their reactions to people who stutter (PWS). Taking differences in age and education into account, we compared reactions to PWS between 263 teachers and 1336 non-teachers in the United States based on their responses on the Public Opinion Survey on Human Attributes-Stuttering (POSHA-S, St. Louis, 2012). Findings indicated that teachers use a greater number and variety of information sources about PWS than the general public and that male teachers do so even more than female teachers. With regard to the other POSHA-S components, accommodating/helping, knowledge/experience, and sympathy/social distancing of PWS, teachers' responses were not significantly different from their non-teaching counterparts. Regardless of occupation, women reported reactions to PWS that are considered more accommodating and helpful to PWS than the reported reactions of men. Readers should be able to: (1) identify the challenges that students who stutter encounter in the K-12 school setting, (2) identify recommended ways teachers can react to their students who stutter, (3) summarize findings regarding teachers' reactions to people who stutter (PWS), and (4) identify key variables that are associated with reactions to PWS.

The purpose of this study was to identify and analyse currently available knowledge on information needs of people with diabetes mellitus, also considering possible differences between subgroups and associated factors. Twelve databases including MEDLINE, EMBASE and the Cochrane Library were searched up until June 2015. Publications that addressed self-reported information needs of people with diabetes mellitus were included. Each study was assessed by using critical appraisal tools, e.g. from the UK National Institute for Health and Care Excellence. Extraction and content analysis were performed systematically. In total, 1993 publications were identified and 26 were finally included. Nine main categories of information needs were identified, including 'treatment-process', 'course of disease', 'abnormalities of glucose metabolism' and 'diabetes through the life cycle'. Differences between patient subgroups, such as type of diabetes or age, were sparsely analysed. Some studies analysed associations between information needs and factors such as participation preferences or information seeking. They found, for example, that information needs on social support or life tasks were associated with information seeking in Internet forums. Information needs in people with diabetes mellitus, appear to be high, yet poorly investigated. Research is needed regarding differences between diverse diabetes populations, including gender aspects or changes in information needs during the disease course. The review protocol has been registered at Prospero ( CRD42015029610 ).

Pacific people in New Zealand are a minority ethnic population identified in national prevalence studies as having the highest risk of developing gambling problems. As earlier studies identified some links between culture and gambling for this population, our study aimed to deepen understanding of these links and their role in explaining the disproportionate gambling harms experienced by Pacific people. To achieve this aim we employed intersectionality as a theoretical framework to explore the culture-gambling intersection for this population group. We analysed data from a subset of focus groups conducted for a broad study of gambling harms in New Zealand. The subset was selected based on the presence of individuals knowledgeable about Pacific people's gambling behaviours, including staff from Pacific problem gambling treatment services who provided examples from a cultural perspective. We identified themes at a latent level via an interpretive process to identify underlying cultural contexts of gambling harms. Findings indicated that whilst harms experienced by Pacific people were similar to those identified amongst the general population, the cultural contexts in which some harms manifested were complex. This paper contributes to the existing knowledge base about gambling harms for Pacific people in relation to six culture-gambling intersecting themes that emerged from the data: collectivism, gift-giving, gambling-based fundraising, patriarchy, beliefs about blessings, and sports celebrities. Findings are discussed in relation to the current knowledge of gambling and conceptualisations of gambling harm within Pacific communities. Implications for culturally appropriate harm minimisation strategies and prevention interventions for this population are suggested.

Supportive care for older people with frailty in hospital: An integrative review.
Nicholson, Caroline; Morrow, Elizabeth M; Hicks, Allan; Fitzpatrick, Joanne
2017-01-01
Growing numbers of older people living with frailty and chronic health conditions are being referred to hospitals with acute care needs. Supportive care is a potentially highly relevant and clinically important approach which could bridge the practice gap between curative models of care and palliative care. However, future interventions need to be informed and underpinned by existing knowledge of supportive care. To identify and build upon existing theories and evidence about supportive care, specifically in relation to the hospital care of older people with frailty, to inform future interventions and their evaluation. An integrative review was used to identify and integrate theory and evidence. Electronic databases (Cochrane Medline, EMBASE and CIHAHL) were searched using the key term 'supportive care'. Screening identified studies employing qualitative and/or quantitative methods published between January 1990 and December 2015. Citation searches, reference checking and searches of the grey literature were also undertaken. Literature searches identified 2733 articles. After screening, and applying eligibility criteria based on relevance to the research question, studies were subject to methodological quality appraisal. Findings from included articles (n=52) were integrated using synthesis of themes. Relevant evidence was identified across different research literatures, on clinical conditions and contexts. Seven distinct themes of the synthesis were identified, these were: Ensuring fundamental aspects of care are met, Communicating and connecting with the patient, Carer and family engagement, Building up a picture of the person and their circumstances, Decisions and advice about best care for the person, Enabling self-help and connection to wider support, and Supporting patients through transitions in care. A tentative integrative model of supportive care for frail older people is developed from the findings. The findings and model developed here will inform

Full Text Available The purpose of the current study was to identify the functional significance of conflicting stereotypes and to identify the dominant category in such conflicts. In the present research we examined the conflicting crossed-categories of age and wealth with regard to warmth and competence perceptions. It was found (Pilot Study and Study 1 that the old-rich targets presented a conflicting stereotype group in the perception of warmth, whereas young-poor targets presented a conflicting stereotype group in the perception of competence. In addition, the old stereotype dominated the warmth evaluation of old-rich targets, whereas the poor stereotype dominated the competence evaluation of young-poor targets. In Study 2, participants provided warmth and competence evaluations after they learned about the targets’ behaviors which demonstrated high or low warmth and high or low competence. The results suggest that for the warmth evaluation of the old-rich target the category that did not match the behavior (i.e., contradicted the stereotype expectation was more salient and drove judgments. However, the effect of stereotype expectation violation was not found in the competence evaluation of the young-poor target. The results are discussed in terms of their implications for understanding factors that activate and inhibit stereotyped perceptions.

Health professionals’ knowledge and attitudes toward older people in primary care in Saudi Arabia
Alamri, Badrya H.; Xiao, Lily D.
2017-01-01
Previous international studies have indicated that a range of factors influence knowledge and attitudes toward older people were education, past work experiences, and social contact with healthy older people. This article reports on the findings of a literature review in relation to attitudes toward older people among health professionals working in primary healthcare centers in Saudi Arabia. The findings of this narrative literature are reported through 5 themes: the instruments used in the selected studies to measure attitudes toward older people; the instruments used to measure knowledge on ageing; attitudes toward older people; knowledge of the care of older people; and factors that influence knowledge and attitudes toward older people. Further investigation is needed to identify the level of knowledge on ageing, attitudes toward older people, and the factors which affect health professionals’ knowledge and attitudes toward older people in primary healthcare centers in Saudi Arabia.

Building on an existing theoretical shared primary care/specialist care framework to (1) develop a unique typology of care for people living with human immunodeficiency virus (HIV) in Ontario, (2) assess sensitivity of the typology by varying typology definitions, and (3) describe characteristics of typology categories. Retrospective population-based observational study from April 1, 2009, to March 31, 2012. A total of 13,480 eligible patients with HIV and receiving publicly funded health care in Ontario. We derived a typology of care by linking patients to usual family physicians and to HIV specialists with five possible patterns of care. Patient and physician characteristics and outpatient visits for HIV-related and non-HIV-related care were used to assess the robustness and characteristics of the typology. Five possible patterns of care were described as low engagement (8.6%), exclusively primary care (52.7%), family physician-dominated comanagement (10.0%), specialist-dominated comanagement (30.5%), and exclusively specialist care (5.2%). Sensitivity analyses demonstrated robustness of typology assignments. Visit patterns varied in ways that conform to typology assignments. We anticipate this typology can be used to assess the impact of care patterns on the quality of primary care for people living with HIV. Copyright © 2015 Elsevier Inc. All rights reserved.

To investigate whether the ocular dominance affects laterality in the activity of the primary visual cortex, we examined the relationship between the ocular dominance and latency or dipole moment measured by checkerboard-pattern and magnetoencephalography in 11 right-handed healthy male participants. Participants with left-eye dominance showed a dipole moment of 21.5+/-6.1 nAm with left-eye stimulation and 16.1+/-3.6 nAm with right, whereas those with right-eye dominance showed a dipole moment of 18.0+/-5.2 and 21.5+/-2.7 nAm with left-eye and right-eye stimulation of the infero-medial quadrant visual field, respectively. Thus, the dipole moment was higher when the dominant eye was stimulated, which implies that ocular dominance is regulated by the ipsilateral occipital lobe.

BACKGROUND: Homeless people have elevated mortality, especially due to external causes. We aimed to examine suicide and unintentional injury mortality levels and identify predictors in the homeless population. METHODS: A nationwide, register-based cohort study of homeless people aged 16 years...... and older was carried out using the Danish Homeless Register, 1999-2008. RESULTS: In all, 32 010 homeless people (70.5% men) were observed. For men, the mortality rate was 174.4 [95% confidence interval (CI) = 150.6-198.1] per 100 000 person-years for suicide and 463.3 (95% CI = 424.......6-502.0) for unintentional injury. For women, the corresponding rates were 111.4 (95% CI = 81.7-141.1) for suicide and 241.4 (95% CI = 197.6-285.1) for unintentional injury. Schizophrenia spectrum, affective, personality and substance use disorders were strongly associated with increased risk of suicide; the highest risk...

The meaning of work in people with severe mental illness (SMI) in Iran.
Khalaf Beigi, Mitra; Mohammadi Shahbolaghi, Farahnaz; Rassafiani, Mehdi; Haghgoo, Hojjat-Allah; Taherkhani, Hamid
2015-01-01
Work is the key component for most people in regard to financial, social and wellbeing matters. Employment is an important factor underpinning mental health disorders. However, unemployment remains an unsolved issue worldwide. Numerous studies have focused on employment outcomes in people with severe mental illness (SMI) but, only a few have explored their perspective on employment. Therefore, this study aimed to clarify the meaning of work among clients with SMI in Iran. A qualitative research approach was used to conduct this research. Ten participants who were consumers of mental health services took part in this study. Data were analyzed by inductive content analysis approach. Four themes emerged from data including: acquiring identity, work as a drive, passing the time and financial independence. Meaning of work in studied people with SMI was probably similar to the general population. The different finding in this study refers to the dominancy of family relationships and spiritual believes which could cover some problems and in turn affect the meaning of work. Highlighting these meanings could direct mental health professionals to better planning for their clients have better understanding of their clients' work future and in turn provide more precise plan for them.

Hypothalamic digoxin, hemispheric chemical dominance, and chronic bronchitis emphysema.
Kurup, Ravi Kumar; Kurup, Parameswara Achutha
2003-09-01
The isoprenoid pathway produces three key metabolites--endogenous digoxin (membrane sodium-potassium ATPase inhibitor, immunomodulator, and regulator of neurotransmitter/amino acid transport), dolichol (regulates N-glycosylation of proteins), and ubiquinone (free radical scavenger). This was assessed in patients with chronic bronchitis emphysema. The pathway was also assessed in patients with right hemispheric, left hemispheric, and bihemispheric dominance to find the role of hemispheric dominance in the pathogenesis of chronic bronchitis emphysema. All the 15 patients with chronic bronchitis emphysema were right-handed/left hemispheric dominant by the dichotic listening test. In patients with chronic bronchitis emphysema there was elevated digoxin synthesis, increased dolichol, and glycoconjugate levels, and low ubiquinone and elevated free radical levels. There was also an increase in tryptophan catabolites and a reduction in tyrosine catabolites. There was an increase in cholesterol:phospholipid ratio and a reduction in glycoconjugate levels of RBC membrane in patients with chronic bronchitis emphysema. The same biochemical patterns were obtained in individuals with right hemispheric dominance. Endogenous digoxin by activating the calcineurin signal transduction pathway of T-cell can contribute to immune activation in chronic bronchitis emphysema. Increased free radical generation can also lead to immune activation. Endogenous synthesis of nicotine can contribute to the pathogenesis of the disease. Altered glycoconjugate metabolism and membranogenesis can lead to defective lysosomal stability contributing to the disease process by increased release of lysosomal proteases. The role of an endogenous digoxin and hemispheric dominance in the pathogenesis of chronic bronchitis emphysema and in the regulation of lung structure/function is discussed. The biochemical patterns obtained in chronic bronchitis emphysema is similar to those obtained in left

Very little is known about the experiences of lesbian, gay, bisexual, and transgender (LGBT) people in relation to mental health services. Therefore, the overall aim of the current research was to explore LGBT people\\'s experiences of mental health service provision in Ireland. The objectives were to identify barriers and opportunities, to highlight service gaps, and to identify good practice in addressing the mental health and well-being of LGBT people. A mixed methods research design using quantitative and qualitative approaches was deployed. A multipronged sampling strategy was used and 125 respondents responded to the questionnaire. A subset of phase 1 (n = 20) were interviewed in the qualitative phase. Quantitative data was analyzed using descriptive statistics. Qualitative data were analyzed thematically. The sample consisted of LGBT people (n = 125) over 18 years of age living in Ireland. Over three-quarters (77%) had received a psychiatric diagnosis. Findings include that whilst 63% of respondents were able to be \\'out\\' to practitioners, 64% felt that mental health professionals lacked knowledge about LGBT issues and 43% felt practitioners were unresponsive to their needs. Finally, respondent recommendations about how mental health services may be more responsive to LGBT people\\'s needs are presented.

Global Equity and Justice Issues for Young People During the First Three Decades of Life.
Petersen, Anne; Koller, Silvia H; Motti-Stefanidi, Frosso; Verma, Suman
This chapter takes a global perspective on equity and justice during development from childhood into adulthood. Globally, the population of young people is booming with the most rapid growth among young people in the poorest countries. While already faced with significant issues related to development and thriving, this population boom also exacerbates equity and justice for these children. Given this urgent situation, this chapter builds from the large body of minority world research, as well as the emergent majority world research, to argue that in order to turn the youth bulge into a demographic dividend, researchers must utilize a positive development framing rather than the more dominant problem-focused framing in studying these issues. The structural challenges confronting young people growing up in contexts marked by poverty; weak systems and institutions, especially those serving education, health, and justice; weak political and governance systems; and continual conflict must also be addressed by global and national governmental bodies. This chapter will emphasize the strengths and opportunities of the majority world, highlighting some of the strong, emergent examples of programs that support and develop the strengths of young people. We conclude with a discussion of appropriate support required from the minority and majority worlds that would further strengthen young people globally and enable them to become leaders of a more just, equitable world. © 2016 Elsevier Inc.

Arguing from a sociobiological perspective, Sidanius and Pratto (1999) have shown that the male/female difference in social dominance orientation (SDO) is largely invariant across cultural, situational and contextual boundaries. The main objective of this study was to test the validity of Social Dominance Theory (SDT) by contrasting it with a model derived from Social Identity Theory (SIT). More specifically, while SIT predicts that gender identification mediates the effect of gender on SDO, SDT predicts the reverse. According to SDT, the degree to which men and women endorse status legitimizing ideology should determine to what extent they identify with their gender group. Using structural equation modelling, the results provide strong support for the SIT model and no support for SDT predictions. Implications of these results for social dominance theory and its sociobiologically based invariance hypothesis are discussed.

Full Text Available In 1947, von Neumann and Morgenstern introduced the well-known expected utility and the related axiomatic system (see von Neumann and Morgenstern (1953. It is widely used in economics, for example, financial economics. But the well-known Allais paradox (see Allais (1979 shows that the linear expected utility has some limitations sometimes. Because of this, Peng proposed a concept of nonlinear expected utility (see Peng (2005. In this paper we propose a concept of stochastic dominance under the nonlinear expected utilities. We give sufficient conditions on which a random choice X stochastically dominates a random choice Y under the nonlinear expected utilities. We also provide sufficient conditions on which a random choice X strictly stochastically dominates a random choice Y under the sublinear expected utilities.

Understanding patterns of plant population mortality during extreme weather events is important to conservation planners because the frequency of such events is expected to increase, creating the need to integrate climatic uncertainty into management. Dominant plants provide habitat and ecosystem structure, so changes in their distribution can be expected to have cascading effects on entire communities. Observing areas that respond quickly to climate fluctuations provides foresight into future ecological changes and will help prioritize conservation efforts. We investigated patterns of mortality in six dominant plant species during a drought in the southwestern United States. We quantified population mortality for each species across its regional distribution and tested hypotheses to identify ecological stress gradients for each species. Our results revealed three major patterns: (1) dominant species from diverse habitat types (i.e., riparian, chaparral, and low- to high-elevation forests) exhibited significant mortality, indicating that the effects of drought were widespread; (2) average mortality differed among dominant species (one-seed juniper[Juniperus monosperma (Engelm.) Sarg.] 3.3%; manzanita[Arctostaphylos pungens Kunth], 14.6%; quaking aspen[Populus tremuloides Michx.], 15.4%; ponderosa pine[Pinus ponderosa P. & C. Lawson], 15.9%; Fremont cottonwood[Populus fremontii S. Wats.], 20.7%; and pinyon pine[Pinus edulis Engelm.], 41.4%); (3) all dominant species showed localized patterns of very high mortality (24-100%) consistent with water stress gradients. Land managers should plan for climatic uncertainty by promoting tree recruitment in rare habitat types, alleviating unnatural levels of competition on dominant plants, and conserving sites across water stress gradients. High-stress sites, such as those we examined, have conservation value as barometers of change and because they may harbor genotypes that are adapted to climatic extremes.

AR4VI: AR as an Accessibility Tool for People with Visual Impairments
Coughlan, James M.; Miele, Joshua
2017-01-01
Although AR technology has been largely dominated by visual media, a number of AR tools using both visual and auditory feedback have been developed specifically to assist people with low vision or blindness – an application domain that we term Augmented Reality for Visual Impairment (AR4VI). We describe two AR4VI tools developed at Smith-Kettlewell, as well as a number of pre-existing examples. We emphasize that AR4VI is a powerful tool with the potential to remove or significantly reduce a r...

Recent developments in suicide prevention among the Indigenous peoples of Australia.
Dudgeon, Pat; Holland, Christopher
2018-04-01
Suicide is an Aboriginal and Torres Strait Islander (hereafter 'Indigenous') population health issue. Over 2015-2016, the Aboriginal and Torres Strait Islander Suicide Prevention Project (ATSISPEP) aimed to identify success factors in Indigenous suicide prevention. For non-Indigenous practitioners working with indigenous clients at risk of suicide, ATSISPEP identified important considerations to make treatment more effective. The start is acknowledging the differences in the historical, cultural, political, social and economic experiences of Indigenous peoples, and their greater exposure to trauma, psychological distress and risks to mental health. These mental health difficulties are specific and more prevalent amongst Indigenous peoples and communities due to the ongoing impacts of colonisation in Australia including a range of social determinants impacting on the well-being of Indigenous peoples today. Working effectively with Indigenous clients also includes being able to establish culturally safe work environments, and the ability of non-Indigenous practitioners to work in a culturally competent and trauma-informed manner. There are also considerations regarding time protocols and client follow-up. Further, postvention responses might be required. Supporting selective suicide prevention activity among younger people (and other groups at increased risk) and community-level work is an important complement to working with Indigenous individuals at risk of suicide.

Social Dominance Theory (Sidanius & Pratto, 1999) stress that systematic inter group discrimination is related to social ideologies that contribute to coordinate institutions and individuals behaviors. The acceptance of inequity legitimating ideologies is partially determined for individuals general desire of group based domination. This desire is captured by Social Orientation Domination construct -SDO. Pursuing the objective of exploring SDO levels and its relationship with variables su...

Aggression as Positive Reinforcement in People with Intellectual Disabilities
May, Michael E.
2011-01-01
From an applied behavior-analytic perspective, aggression in people with intellectual disabilities is mostly maintained by social reinforcement consequences. However, nonsocial consequences have also been identified in functional assessments on aggression. Behaviors producing their own reinforcement have been labeled "automatic" or "nonsocial" in…

Anophthalmia/microphthalmia (A/M) is a developmental ocular malformation defined as complete absence or reduction in size of the eye. A/M is a heterogenous disorder with numerous causative genes identified; however, about half the cases lack a molecular diagnosis. We undertook whole exome sequencing in an A/M family with two affected siblings, two unaffected siblings, and unaffected parents; the ocular phenotype was isolated with only mild developmental delay/learning difficulties reported and a normal brain magnetic resonance imaging (MRI) in the proband at 16 months. No pathogenic mutations were identified in 71 known A/M genes. Further analysis identified a shared heterozygous mutation in COL4A1, c.2317G>A, p.(Gly773Arg) that was not seen in the unaffected parents and siblings. Analysis of 24 unrelated A/M exomes identified a novel c.2122G>A, p.(Gly708Arg) mutation in an additional patient with unilateral microphthalmia, bilateral microcornea and Peters anomaly; the mutation was absent in the unaffected mother and the unaffected father was not available. Mutations in COL4A1 have been linked to a spectrum of human disorders; the most consistent feature is cerebrovascular disease with variable ocular anomalies, kidney and muscle defects. This study expands the spectrum of COL4A1 phenotypes and indicates screening in patients with A/M regardless of MRI findings or presumed inheritance pattern. © 2014 John Wiley & Sons A/S.

Massage therapy for people with HIV/AIDS.
Hillier, Susan L; Louw, Quinette; Morris, Linzette; Uwimana, Jeanine; Statham, Sue
2010-01-20
Infection with human immunodeficency virus (HIV) and acquired immunodeficency syndrome (AIDS) is a pandemic that has affected millions of people globally. Although major research and clinical initiatives are addressing prevention and cure strategies, issues of quality of life for survivors have received less attention. Massage therapy is proposed to have a positive effect on quality of life and may also have a positive effect on immune function through stress mediation. The objective of this systematic review was to examine the safety and effectiveness of massage therapy on quality of life, pain and immune system parameters in people living with HIV/AIDS. A comprehensive search strategy was devised incorporating appropriate terms for HIV/AIDS, randomised controlled trials (RCTs), massage therapy and the pertinent measures of benefit. All electronic databases identified were searched in November 2008, including Cochrane Group Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, SCIENCE CITATION INDEX, AIDSLINE, AIDSearch, CINAHL, HEALTHSTAR, PsycLIT, AMED, Current Contents, AMI, NLM GATEWAY, LILACS, IndMed, SOCIOFILE, SCI, SSCI, ERIC and DAI. We also reviewed relevant published and unpublished conference abstracts and proceedings and scrutinised reference lists from pertinent journals. There were no language or date restrictions. Studies were identified by two reviewers based on trial design (RCTs) and participants (ie, people of any age with HIV/AIDS, at any stage of the disease) who had undergone an intervention that included massage therapy for the identified aims of improving quality of life and activity and participation levels, improving immune function, reducing pain and improving other physiological or psychological impairments. Two reviewers independently identified included studies and extracted relevant data. Two other reviewers independently reviewed the included studies for risk of bias. All data and risk of bias

In the context of a U.S. dominant masculinity ideology, which devalues men who are not heterosexually identified, many gay, bisexual and questioning (GBQ) adolescent males must develop their own affirming and health-promoting sense of masculinity. In order to promote the well-being of GBQ young men, exploration of their reactions and responses to dominant images of masculinity is needed. We qualitatively analyzed interviews with 39 GBQ African American, Latino, and European American male adolescents (15–23 years old). Participants reported a range of responses to traditional masculinity ideologies, most of which centered on balancing presentations of masculine and feminine characteristics. Negotiation strategies served a variety of functions, including avoiding anti-gay violence, living up to expected images of masculinity, and creating unique images of personhood free of gender role expectations. These data suggest a complex picture of GBQ male adolescents’ management of masculinity expectations and serve as a basis for culturally and developmentally specific HIV prevention programs.

Optimising nutrition for older people with dementia.
Cole, Delwyn
This article explores interventions that can be undertaken to establish and maintain adequate nutritional intake in older people with dementia. This is often a problem, particularly in the later stages of the disease. A literature review was conducted, which identified 12 articles for inclusion. Most of these articles described interventions to maintain adequate nutritional intake in older adults with dementia. Although no standardised intervention was reported, some approaches did appear to be more successful than others. Further research is required on how nurses and nursing assistants can help older people with dementia to maintain adequate nutrition. Staff need more time and training to improve nutritional intake in this group of patients. In addition, enhanced vigilance with respect to eating difficulties and food consumption is necessary.

We assess life history from birth to death in male mandrills (Mandrillus sphinx) living in a semifree-ranging colony in Gabon, using data collected for 82 males that attained at least the age of puberty, including 33 that reached adulthood and 25 that died, yielding data for their entire lifespan. We describe patterns of mortality and injuries, dominance rank, group association, growth and stature, and secondary sexual character expression across the male lifespan. We examine relationships among these variables and investigate potential influences on male life history, including differences in the social environment (maternal rank and group demography) and early development, with the aim of identifying characteristics of successful males. Sons of higher-ranking females were more likely to survive to adulthood than sons of low-ranking females. Adolescent males varied consistently in the rate at which they developed, and this variation was related to a male's own dominance rank. Males with fewer peers and sons of higher-ranking and heavier mothers also matured faster. However, maternal variables were not significantly related to dominance rank during adolescence, the age at which males attained adult dominance rank, or whether a male became alpha male. Among adult males, behavior and morphological development were related to a male's own dominance rank, and sons of high-ranking females were larger than sons of low-ranking females. Alpha males were always the most social, and the most brightly colored males, but were not necessarily the largest males present. Finally, alpha male tenure was related to group demography, with larger numbers of rival adult males and maturing adolescent males reducing the time a male spent as alpha male. Tenure did not appear to be related to characteristics of the alpha male himself. 2006 Wiley-Liss, Inc.

Hypothalamic digoxin, hemispheric chemical dominance, and mesenteric artery occlusion.
Kurup, Ravi Kumar; Kurup, Paramesware Achutha
2003-12-01
The role of the isoprenoid pathway in vascular thrombosis, especially mesenteric artery occlusion and its relation to hemispheric dominance, was assessed in this study. The following parameters were measured in patients with mesenteric artery occlusion and individuals with right hemispheric, left hemispheric, and bihemispheric dominance: (1) plasma HMG CoA reductase, digoxin, dolichol, ubiquinone, and magnesium levels; (2) tryptophan/tyrosine catabolic patterns; (3) free radical metabolism; (4) glycoconjugate metabolism; and (5) membrane composition. In patients with mesenteric artery occlusion there was elevated digoxin synthesis, increased dolichol and glycoconjugate levels, low ubiquinone, and elevated free radical levels. The RBC membrane Na(+)-K+ ATPase activity and serum magnesium were decreased. There was also an increase in tryptophan catabolites and reduction in tyrosine catabolites in the serum. There was an increase in cholesterol:phospholipid ratio and a reduction in glycoconjugate level of RBC membrane in these patients. The biochemical patterns obtained in mesenteric artery occlusion is similar to those obtained in left-handed/right hemispheric dominant individuals by the dichotic listening test. But all the patients with mesenteric artery occlusion were right-handed/left hemispheric dominant by the dichotic listening test. Hemispheric chemical dominance has no correlation with handedness or the dichotic listening test. Mesenteric artery occlusion occurs in right hemispheric chemically dominant individuals and is a reflection of altered brain function. Hemispheric chemical dominance may thus control the risk for developing vascular thrombosis in individuals.

Different Vocal Parameters Predict Perceptions of Dominance and Attractiveness.
Hodges-Simeon, Carolyn R; Gaulin, Steven J C; Puts, David A
2010-12-01
Low mean fundamental frequency (F(0)) in men's voices has been found to positively influence perceptions of dominance by men and attractiveness by women using standardized speech. Using natural speech obtained during an ecologically valid social interaction, we examined relationships between multiple vocal parameters and dominance and attractiveness judgments. Male voices from an unscripted dating game were judged by men for physical and social dominance and by women in fertile and non-fertile menstrual cycle phases for desirability in short-term and long-term relationships. Five vocal parameters were analyzed: mean F(0) (an acoustic correlate of vocal fold size), F(0) variation, intensity (loudness), utterance duration, and formant dispersion (D(f), an acoustic correlate of vocal tract length). Parallel but separate ratings of speech transcripts served as controls for content. Multiple regression analyses were used to examine the independent contributions of each of the predictors. Physical dominance was predicted by low F(0) variation and physically dominant word content. Social dominance was predicted only by socially dominant word content. Ratings of attractiveness by women were predicted by low mean F(0), low D(f), high intensity, and attractive word content across cycle phase and mating context. Low D(f) was perceived as attractive by fertile-phase women only. We hypothesize that competitors and potential mates may attend more strongly to different components of men's voices because of the different types of information these vocal parameters provide.

Older people's experiences of dream coaching.
Wadensten, Barbro
2009-12-01
Recalling and talking about dreams could initiate dream work among older people and provide an opportunity for self-confrontation and personal growth, which could in turn promote gerotranscendental development. The present article describes older people's opinions about participating in a dream-coaching group; it also briefly describes the theoretical foundation of dream coaching. The study aim was to investigate older people's experience of participating in a dream-coaching group based on Jungian psychology. A descriptive design was used. Retrospective interviews were explored using qualitative content analysis. The participants were satisfied with the arrangement of the dream-coaching groups. All participants believed that they had recalled their dreams and thought much more about their dreams during the period in which the dream-coaching group met. Three diverse appraisals of participating in a dream-coaching group, which had different effects on the participants, were identified: "An activity like any other activity," "An activity that led to deeper thoughts about the meaning of dreams," and "An activity that led to deeper thoughts both about the meaning of dreams and about how dreams can improve one's understanding of the life situation." It is possible to arrange dream-coaching groups for older people and could be a way to promote personal development using this type of intervention. The study provides some guidance as to how such a group could be organized, thus facilitating use of dream-coaching groups in gerontological care.
