Satisfying relationships are important to the well-being of individuals and families. Because of increased longevity, many couples are staying together for extended periods of time. Thus, it is valuable to understand the factors that contribute to a sense of satisfaction among partners in lasting relationships. Relatively little attention has been paid in the research literature to relationships among older couples who have remained together for many years. Even less attention has been paid to the lasting relationships of couples of color and to gay male and lesbian couples. This paper focuses on understanding the factors that contribute to satisfaction of partners in the long-term relationships of a purposive sample of heterosexual and same-sex couples. Data was collected through in-depth interviews with 216 partners in 108 relationships that had lasted an average of 30 years. Using logistic regression analysis, two factors were identified as predictive of satisfaction during the recent years of these relationships: containment of relational conflict and psychologically intimate communication between partners. Based on these findings, a theoretical model for understanding satisfaction in lasting relationships is discussed.

Full Text Available Abstract Background Discrepancies between parents and children in their assessment of children's mental health affect the evaluation of need for services and must be taken seriously. This article presents the differences between parents' and children's reports of the children's symptoms and social impairment, based on the results of the Strengths and Difficulties Questionnaire (SDQ. The interrelationship between relational aspects and socio-demographic factors with patterns of disagreement are explored. Methods Differences in the prevalence and means of SDQ symptom and impact scores were obtained from 8,154 primary school children, aged between 10 and 13 years, and their parents. Agreement between matched pairs was measured using Pearson's and Spearman's rho correlations. Socio-demographic variables, communication patterns and parental engagement were analysed as possible correlates of informant discrepancies using bivariate and multivariate logistic regression models. Results In general, although children reported more symptoms, they reported less impact of perceived difficulties than parents. The parents were more consistent in their evaluation of symptoms and impact than were the children. Exploration of highly discrepant subgroups showed that, when children reported the most symptoms and impact, qualitative aspects of the parent-child relationship and family structure seemed to be more powerful predictors of disagreement than were gender of the child and socio-demographic variables. When parents reported the most symptoms and impact, low parental educational level, low income and male gender of the child played an additional role. Conclusions Our findings underline the importance of paying attention to child reports of emotional-behavioural difficulties, particularly when parents do not identify these problems. Considerations on what meaning parent-child discrepancy might have in the context of the parent-child relationship or the family

To explore the factors that contribute to children's screen-related sedentary (S-RS) behaviors. Elementary schools. A random sample of children in grades five and six and their parents. The outcome measure was children's S-RS activity level measured by a self-administered questionnaire. A full spectrum of potential contributing factors for children's S-RS behaviors was obtained through surveys. Multilevel linear regression methods were used to determine the associations between these factors and children's screen time (hours per day) and results were expressed as regression coefficients (g). Of 955 child-parent pairs in 14 participating schools, 508 pairs (53%) completed the surveys. At an intrapersonal level, protective factors included being a girl (g = -.71); belonging to a sports team inside (g = -.56) or outside (g = -.49) of school; having a negative attitude toward S-RS activities (g = -.13); and having a positive attitude toward physical activity (g = .48). At the interpersonal and social levels, parental leisure S-RS behaviors (g = .32) were positively associated, whereas strict parental rules on computer use (g = -.27) and family income (g = -.32) were inversely correlated with S-RS behavior. At the environmental level, the presence of TVs in children's bedrooms (g = .44) and owning videogame devices (g = .58) increased the risk of S-RS behaviors, whereas after school programs (g = - .86) and schools' participation in the Turn Off the Screen Week campaign (g = -.91) decreased the risk. Public health interventions should target multilevel factors, including increasing children's awareness, promoting parental involvement in healthy lifestyle pursuits, and creating less screenogenic environments.

To examine correlates of suicide attempts among American Indian adolescents living on reservations in New Mexico. Cross-sectional American Indian adolescents attending school in New Mexico, grades 6 to 12. Data from the Search Institute Profiles of Student Life Attitudes and Behaviors survey related to suicide attempts and student assets and risk behaviors. Hypothesized predictor variables derived from 39 survey questions were tested against one outcome variable relating to prior suicide attempts. Of 690 American Indian students included in the study, 24.2% indicated having attempted suicide one or more times in their lives. Salient assets included having neighbors who cared about them, adults who made them feel important, and having friends who did well in school. Notable risk factors were feeling depressed, drug and alcohol use, and having been the victim of violence. Adolescent suicide continues to be a major concern for American Indians. A focus on strengthening parent-child relationships and community support for families may increase resiliency among youth at risk.

Psychopathic traits reflect deficits in behavioral, affective, and interpersonal functioning (Cooke & Michie, 2001). Children with poor inhibitory control may display these traits. Maternal sensitivity and attachment have been implicated in psychopathic traits, but whether they may reduce the likelihood of psychopathic trait expression in adolescence for uninhibited children is largely unknown. The current study attempted to shed light on this issue. Data came from 957 adolescents, followed from 54 months through 15 years. Findings demonstrated that maternal sensitivity was associated with a reduced likelihood of psychopathic traits for males with low inhibitory control. For females, secure attachment mediated the interaction of sensitivity and inhibitory control to psychopathic traits. The current study offers insight into the temperamental traits, parenting, and relational processes involved in psychopathic trait expression during adolescence.

Over a period of time, the author arrived at a few tentative postulates concerning empathy and related processes based on some of his experiences and observations. The central theme of these postulates is, firstly, that interpersonal interaction is an interaction of the personal-space fields. Secondly, empathy, therapeutic benefit, and the professional stress are all related to the same process of interpersonal interaction. This interaction takes place as an enmeshment of personal spaces of the interacting individuals, and involves transfer of a wide range of information in the affective, cognitive, and other areas. This is because the personal spaces have fieldlike qualities analogous to what Kurt Lewin described. Thus, such phenomena as empathy, therapeutic benefit, professional stress are all consequences of the same process. It is possible to substantiate these postulates by diverse evidences in the published literature. The natural consequences of such an interpersonal interaction are empathic understanding, transfer of mood states (like hope, distress or expectancy), affective states (like anxiety, sadness, anger or hostility), ideas, images and even attitudes and values, etc. This phenomenon of transfer can explain such processes as therapeutic benefit in individual and group settings, professional stress, shared delusions, and even experimenter bias. Whether one becomes aware of such transferred information or not depends upon the intent and sensitivity of the participants.

To explore the effect of health-related and contextual factors on presenteeism, absenteeism, and overall work productivity loss in patients with active ankylosing spondylitis (AS). Consecutive patients with AS starting their first tumor necrosis factor inhibitor and in paid employment were eligible. Patients completed the Work Productivity and Activity Impairment (WPAI) questionnaire for AS to assess presenteeism, absenteeism, and overall work productivity loss in the previous 7 days. In addition, they answered questions about work characteristics (type, characteristics of workplace, satisfaction of contacts with colleagues, and importance of work in life) and health status [Bath AS Functional Index (BASFI), AS Disease Activity Score-C-reactive protein (ASDAS-CRP)]. Physicians assessed the Bath Ankylosing Spondylitis Metrology Index, presence of articular and extraarticular manifestations, comorbidities, and laboratory indicators of inflammation. Stepwise regression models were computed to determine which work-related and health-related factors contributed to WPAI outcomes. The study included 80 patients. The WPAI presenteeism, absenteeism, and overall work productivity loss scores were 49.1%, 30.2%, and 53.1%, respectively. Presenteeism was associated with higher BASFI, female sex, and poor quality of contact with colleagues. Absenteeism was associated with increasing age, current smoking status, higher ASDAS-CRP, and low importance of work for life. Overall work productivity loss was associated with female sex, higher BASFI, past adaptation of job because of illness, number of working hours, and manual profession. Both health-related and contextual factors contribute to work limitations in patients with AS and suggest additional opportunities for improvement by addressing the working environment.
Understanding the relative contributions of direct environmental effects and passive genotype-environment correlations in the association between familial risk factors and child disruptive behavior disorders.

Previous work reports an association between familial risk factors stemming from parental characteristics and offspring disruptive behavior disorders (DBDs). This association may reflect (a) the direct effects of familial environment and (b) a passive gene-environment correlation (r(GE)), wherein the parents provide both the genes and the environment. The current study examined the contributions of direct environmental influences and passive r(GE) by comparing the effects of familial risk factors on child DBDs in genetically related (biological) and non-related (adoptive) families. Participants were 402 adoptive and 204 biological families. Familial environment was defined as maternal and paternal maladaptive parenting and antisociality, marital conflict and divorce; offspring DBDs included attention deficit hyperactivity disorder (ADHD), conduct disorder (CD) and oppositional defiant disorder (ODD). Mixed-level regressions estimated the main effects of familial environment, adoption status and the familial environment by adoption status interaction term, which tested for the presence of passive r(GE). There was a main effect of maternal and paternal maladaptive parenting and marital discord on child DBDs, indicating a direct environmental effect. There was no direct environmental effect of maternal or paternal antisociality, but maternal and paternal antisociality had stronger associations with child DBDs in biological families than adoptive families, indicating the presence of a passive r(GE). Many familial risk factors affected children equally across genetically related and non-related families, providing evidence for direct environmental effects. The relationship of parental antisociality and offspring DBDs was best explained by a passive r(GE), where a general vulnerability toward externalizing psychopathology is passed down by the parents to the children.

Full Text Available Objectives: Reports are indicating of increasing trend of aging and disability in the developing countries while such disabilities are decreasing within the developed countries. This study designed to evaluate the disability and some of its related factors among the elderly population (65 and older in Kashan, Iran. Methods & Materials: A cross-sectional analytical study was conducted on a multi-stage random sample of 350 elderly people (65 year and older in Kashan. The WHO-DAS-II was used as the generic disability measure. The questionnair had 48 questions. The range of score could be between 0-144. Chi-square, t-test analysis and ANOVA were utilized to check significant differences between subgroups. Results: 61% were men and 12% were living lonely. One fourth had some type of addiction, the majority were ilitrate and two thired had not regular phisycal activity.Twenty percent of the old people had a modereate disability and 4.3% were extremely disabled. A significant relationship was found between the disability and variables such as sex, age, living style, needing help, marriage status, living location, addiction, job, level of physical activity, education, and having multiple diseases. Conclusion: In conclusion, geriatric population in Iran, has a lower levels of disability in compare to those of other developed countries. Need of geriatric cares must be be increasing, since the populationpattern of elderly people is increasing in Iran. Female and ilitrate elders were sufering of more disability. These findings indicated the nessesity to more attention to these voulnarable subgroups of population.

This study examined juvenile justice-involved youths' understanding and appreciation of the Miranda warnings' rights to silence and legal counsel using the Miranda Rights Comprehension Instruments (Goldstein, Zelle, & Grisso, 2012). It also examined the relationships between totality of circumstances factors and understanding and appreciation of rights. Data were collected from 183 youths (140 boys) in pre- and postadjudication facilities in 2 states. Overall, youths demonstrated greater difficulty on measures of appreciation than understanding, with particular deficits in their abilities to comprehend the abstract concept of the right to silence. Results varied slightly by instrument, highlighting the importance of a multimodal assessment of these complex abilities. Examination of totality of circumstances factors identified relationships between some factors (e.g., age, verbal IQ, academic achievement) and Miranda comprehension, but revealed that other factors (e.g., gender, number of previous arrests) were not significantly related to Miranda understanding or appreciation. The findings support a nuanced conceptualization of Miranda rights comprehension that acknowledges the complexity of understanding and appreciating the warnings. Empirical analyses also support the continued use of some totality of circumstances factors and abandonment of others. Findings underscore the necessity of multimodal assessment and interpretation when conducting capacity to waive Miranda rights evaluations. (c) 2015 APA, all rights reserved).

We describe how we think of identity as relational, distributed, performed, and fluid, and we illustrate the use of this conceptualization within a narrative worldview. Drawing on the work of Michael White, we describe how this relational view of identity leads to therapeutic responses that give value to interconnection across multiple contexts and that focus on becoming rather than on being. We show how a narrative worldview helps focus on the relational, co-evolving perspective that was the basis of our early attraction to family therapy. We offer detailed examples from our work of practices that help us stay firmly situated in a relational worldview that is counter to the pervasive influence of individualism in our contemporary culture. © 2016 Family Process Institute.

Mermin, N David
In It's About Time, N. David Mermin asserts that relativity ought to be an important part of everyone's education--after all, it is largely about time, a subject with which all are familiar. The book reveals that some of our most intuitive notions about time are shockingly wrong, and that the real nature of time discovered by Einstein can be rigorously explained without advanced mathematics. This readable exposition of the nature of time as addressed in Einstein's theory of relativity is accessible to anyone who remembers a little high school algebra and elementary plane geometry. The book evolved as Mermin taught the subject to diverse groups of undergraduates at Cornell University, none of them science majors, over three and a half decades. Mermin's approach is imaginative, yet accurate and complete. Clear, lively, and informal, the book will appeal to intellectually curious readers of all kinds, including even professional physicists, who will be intrigued by its highly original approach.

The authors conducted a survey of university students' understanding level about words related to nuclear power before and after Fukushima Daiichi Power Plant accident, and analyzed the difference between before and after the accident. The results show that university students' understanding level improved after the accident, especially in the case of reported words by mass media. Understanding level of some nuclear power security words which were not reported so much by mass media also improved. That may be caused by rising of people's concern about nuclear power generation after the accident, and there is a possibility that the accident motivated people to access such words via internet, journals, etc. (author)

Age-related maculopathy (ARM) is the leading cause of blindness in the elderly. Although beneficial therapeutic strategies have recently begun to emerge, much remains unclear regarding the etiopathogenesis of this disorder. Epidemiologic studies have enhanced our understanding of ARM, but the data, often conflicting, has led to difficulties with drawing firm conclusions with respect to risk for this condition. As a consequence, we saw a need to assimilate the published findings with respect to risk factors for ARM, through a review of the literature appraising results from published cross-sectional studies, prospective cohort studies, case series, and case control studies investigating risk for this condition. Our review shows that, to date, and across a spectrum of epidemiologic study designs, only age, cigarette smoking, and family history of ARM have been consistently demonstrated to represent risk for this condition. In addition, genetic studies have recently implicated many genes in the pathogenesis of age-related maculopathy, including Complement Factor H, PLEKHA 1, and LOC387715\\/HTRA1, demonstrating that environmental and genetic factors are important for the development of ARM suggesting that gene-environment interaction plays an important role in the pathogenesis of this condition.

Undreiu, Lucian M.
In most liberal arts colleges the prerequisites for College Physics, Introductory or Calculus based, are strictly related to Mathematics. As a state of fact, the majorities of the students perceive Physics as a conglomerate of mathematical equations, a collection of facts to be memorized and they regard Physics as one of the most difficult subjects. A change of this attitude towards Physics, and Science in general, is intrinsically connected with the promotion of conceptual understanding and stimulation of critical thinking. In such an environment, the educators are facilitators, rather than the source of knowledge. One good way of doing this is to challenge the students to think about what they see around them and to connect physics with the real world. Motivation occurs when students realize that what was learned is interesting and relevant. Visual teaching aids such as educational videos or computer simulations, as well as computer-assisted experiments, can greatly enhance the effectiveness of a science lecture or laboratory. Difficult topics can be discussed through animated analogies. Special Relativity is recognized as a challenging topic and is probably one of the most misunderstood theories of Physics. While understanding Special Relativity requires a detachment from ordinary perception and every day life notions, animated analogies can prove to be very successful in making difficult topics accessible.

In this article, we elaborate on 10 current research questions related to the "teaching games for understanding" (TGfU) approach with the objective of both developing the model itself and fostering game understanding, tactical decision making, and game-playing ability in invasion and net/wall games: (1) How can existing scientific approaches from different disciplines be used to enhance game play for beginners and proficient players? (2) How can state-of-the-art technology be integrated to game-play evaluations of beginners and proficient players by employing corresponding assessments? (4) How can complexity thinking be utilized to shape day-to-day physical education (PE) and coaching practices? (5) How can game making/designing be helpfully utilized for emergent learning? (6) How could purposeful game design create constraints that enable tactical understanding and skill development through adaptive learning and distributed cognition? (7) How can teacher/coach development programs benefit from game-centered approaches? (8) How can TGfU-related approaches be implemented in teacher or coach education with the goal of facilitating preservice and in-service teachers/coaches' learning to teach and thereby foster their professional development from novices to experienced practitioners? (9) Can the TGfU approach be considered a helpful model across different cultures? (10) Can physical/psychomotor, cognitive, affective/social, and cultural development be fostered via TGfU approaches? The answers to these questions are critical not only for the advancement of teaching and coaching in PE and sport-based clubs, but also for an in-depth discussion on new scientific avenues and technological tools.

The behaviour of children in foster care is influenced by a variety of factors including previous experiences of maltreatment and adverse parenting, as well as the impact of separation from birth parents and placement in care. These factors make it difficult for foster parents to accurately interpret the child's behavioural cues, a necessary precursor to sensitive parenting. The relational learning framework introduced in this article, drawing on attachment theory, facilitates the foster parents' access to some features of the child's mental representations, or internal working model, which may be pivotal in understanding the child's behaviour and therefore successfully managing it. Recent studies suggest that parents' ability to understand the child's psychological perspective, or mental state, is related to the child's cognitive and social development. This article presents a method to enhance the foster parents' understanding of the child's psychological perspective. The model is currently being evaluated for use with foster parents, mental health and social work practitioners. © The Author(s) 2014.
Full Text Available We present a model of disease transmission on a regular and small world network and compare different control options. Comparison is based on a total cost of epidemic, including cost of palliative treatment of ill individuals and preventive cost aimed at vaccination or culling of susceptible individuals. Disease is characterized by pre-symptomatic phase, which makes detection and control difficult. Three general strategies emerge: global preventive treatment, local treatment within a neighborhood of certain size and only palliative treatment with no prevention. While the choice between the strategies depends on a relative cost of palliative and preventive treatment, the details of the local strategy and, in particular, the size of the optimal treatment neighborhood depend on the epidemiological factors. The required extent of prevention is proportional to the size of the infection neighborhood, but depends on time till detection and time till treatment in a non-nonlinear (power law. The optimal size of control neighborhood is also highly sensitive to the relative cost, particularly for inefficient detection and control application. These results have important consequences for design of prevention strategies aiming at emerging diseases for which parameters are not nessecerly known in advance.

This study compared the relative response of various screen-film and computed radiography (CR) systems to diagnostic radiation exposure. An analytic model was developed to calculate the total energy deposition within the depth of screen and the readout signal generated from this energy for the x-ray detection system. The model was used to predict the relative sensitivity of several screen-film and CR systems to scattered radiation as a function of various parameters, such as x-ray spectra, phantom thickness, phosphor composition, screen thickness, screen configuration (single front screen, single back screen, screen pair), and readout conditions. In addition, measurements of the scatter degradation factor (SDF) for different screen systems by using the beam stop technique with water phantoms were made to verify the model results. Theoretically calculated values of SDF were in good agreement with experimental data. These results are consistent with the common observation that rare-earth screens generally produce better image quality than calcium tungstate screens and the CR screen.

Full Text Available This study was designed to address individual differences in aided speech understanding among a relatively large group of older adults. The group of older adults consisted of 98 adults (50 female and 48 male ranging in age from 60 to 86 (mean = 69.2. Hearing loss was typical for this age group and about 90% had not worn hearing aids. All subjects completed a battery of tests, including cognitive (6 measures, psychophysical (17 measures, and speech-understanding (9 measures, as well as the Speech, Spatial and Qualities of Hearing (SSQ self-report scale. Most of the speech-understanding measures made use of competing speech and the non-speech psychophysical measures were designed to tap phenomena thought to be relevant for the perception of speech in competing speech (e.g., stream segregation, modulation-detection interference. All measures of speech understanding were administered with spectral shaping applied to the speech stimuli to fully restore audibility through at least 4000 Hz. The measures used were demonstrated to be reliable in older adults and, when compared to a reference group of 28 young normal-hearing adults, age-group differences were observed on many of the measures. Principal-components factor analysis was applied successfully to reduce the number of independent and dependent (speech understanding measures for a multiple-regression analysis. Doing so yielded one global cognitive-processing factor and five non-speech psychoacoustic factors (hearing loss, dichotic signal detection, multi-burst masking, stream segregation, and modulation detection as potential predictors. To this set of six potential predictor variables were added subject age, Environmental Sound Identification (ESI, and performance on the text-recognition-threshold (TRT task (a visual analog of interrupted speech recognition. These variables were used to successfully predict one global aided speech-understanding factor, accounting for about 60% of the variance.
Full Text Available The goal of this article is to answer the question in what way relational marketing and in particular, the concept of relational benefits, as well as quality of relation may influence the transfer of knowledge and technologies from universities to business. Another goal is to highlight significant, future directions of research in this area. Integration of the theory of relational marketing and technology transfer may create a new framework for fuller understanding of the ties between science and business. Research in this area may contribute to the expansion and development of the theory of relational marketing, which until now was limited to the analysis of relations within a single sector. The results of conducted research show that ties characterized by high relational engagement are common, recognized by both academic and business environment as precious and play an important role in stimulating innovations. The quality of relations and relational benefits may play an important role in building long-term ties between universities and the industry. Integration of behavioural theories with the theory of technology transfer may contribute to a better understanding of the behaviour of particular participants of the transfer on the individual level.
The author's purpose in this article is to describe the effectiveness of video-cued narrative reflection as a research approach for accessing relational, practice-based, and lived understandings. Video-cued narrative reflection provides moment-by-moment access to tacit experience. The immediate nature of the videotape captures emotional nuances, embodied perceptions, spatial influences, relational understandings, situational factors, and temporal manifestations. By watching videotaped interactions, participants are able to re-collect, re-experience, and interpret their life world. Video-cued narrative reflection allows participants to be simultaneously engaged and reflective while describing significant understandings. By inserting audiotaped reflective commentary of participants into the original videotape transcript, contextual meanings can be located and articulated more easily. Although not appropriate for all types of research, this approach offers promise for certain studies.

This study proposes a psychometric approach to assess the General Factor of Personality (GFP) to explain the whole personality. This approach defends the existence of one basic factor that represents the overall personality. The General Factor of Personality Questionnaire (GFPQ) is presented to measure the basic, combined trait of the complete personality. The questionnaire includes 20 items and is constituted by two scales with 10 items each one: the Extraversion Scale (ES) and the Introversion Scale (IS). The GFPQ shows adequate internal consistency and construct validity, while the relationships with the personality factors of other models and with psychopathology are as expected. It correlates positively and significantly with Extraversion (E) and Psychoticism (P), and negatively with Neuroticism (N) of Eysenck's EPQ (Eysenck Personality Questionnaire); it correlates positively and significantly with the Sensation Seeking Scaled (SSS) of Zuckerman, and is inside the expected direction with Sensitivity to Reward (SR) and Sensitivity to Punishment (SP) of the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ), which represent the approach and avoidance trends of behavior, respectively. It not only relates negatively with the personality disorders of the anxiety spectrum, but also with the emotional disorders in relation to anxiety and depression, and it relates positively with the antisocial personality disorder.

We report quantitative relations between corruption level and economic factors, such as country wealth and foreign investment per capita, which are characterized by a power law spanning multiple scales of wealth and investment per capita. These relations hold for diverse countries, and also remain stable over different time periods. We also observe a negative correlation between level of corruption and long-term economic growth. We find similar results for two independent indices of corruption, suggesting that the relation between corruption and wealth does not depend on the specific measure of corruption. The functional relations we report have implications when assessing the relative level of corruption for two countries with comparable wealth, and for quantifying the impact of corruption on economic growth and foreign investment.

Full Text Available The article aims to identify the role of the Baltic factor in Russia-France relations. Despite the fact that the Baltic Sea region (BSR no longer plays an important role in Russia-France bilateral relations, the authors attach significance to analysing the dynamics and changes of the BSR role in European politics in the post- Napoleonic period. The authors compare the Russian and the July Monarchies (1830—1848 in the context of the current Vienna system of international relations. The article describes the role of the 1830—1831 uprising in Poland, which was an event of particular importance. The monarchies of the two countries had to take into account new social phenomena, which were more pronounced in France. After the suppression of the uprising in the Polish part of the Russian Empire, Polish emigrants residing in France became the stumbling block for the development of Russia- France relations. The article explores the role of P. de Barante, Ambassador of France to Russia and describes France and Russia’s trade and economic interests in the Baltic Sea region. The authors conclude that the specificity of Russia-France bilateral relations became more apparent during the First and Second World Wars. However, the Baltic factor has lost its relevance over time.

Verbal coercion (VC) is a common sexual assault (SA) tactic whereby men and women can be victims or perpetrators. College study abroad students report engagement in casual sex, alcohol consumption, and immersion in a sexualized environment (eg, an environment that supports or encourages sexual activity); factors highly associated with SA in general. The purpose of this study was to examine casual sex, alcohol use, and sexualized environments with VC victimization (VCV) and perpetration (VCP) while abroad. Study abroad students (N = 130) completed questionnaires on alcohol use, casual sex, immersion in a sexualized environment, and VC experiences. Participants were more likely to report both VCV and VCP while abroad if they immersed themselves in a sexualized environment; identifying as male was associated with VCP. Results can inform intervention by providing directors with specific constructs to discuss in pre-departure meetings, such as the influence of the environment on VC.
Full Text Available It is apparent that IT resources are important for organisations. It is also clear that organisations unique competencies, their IT-related capabilities, leverage the IT resources uniquely to create and sustain competitive advantage. However, IT resources are dynamic, and evolve at an exponential rate. This means that organisations will need to sustain their competencies to leverage opportunities offered by new IT resources. Research on ways to sustain IT-related capabilities is limited and a deeper understanding of this situation is important. Amongst other factors, a possible reason for this lack of progress in this area could be due to the lack of validated measurement items of the theoretical constructs to conduct such studies. We suggest an environment in which organisations could build new and sustain their existing IT-related capabilities. We then report on the development of valid and reliable measures for this environment. The validated measures would be useful in extending our understanding on how firms could sustain their IT-related capabilities. This effort will provide a deeper understanding of how firms can secure sustainable IT-related business value from their acquired IT resources.

Full Text Available Abstract Background Depression is one of the most common mental disorders in Western countries and is related to increased morbidity and mortality from medical conditions and decreased quality of life. The sociodemographic factors of age, gender, marital status, education, immigrant status, and income have consistently been identified as important factors in explaining the variability in depression prevalence rates. This study evaluates the relationship between depression and these sociodemographic factors in the province of Ontario in Canada using the Canadian Community Health Survey, Cycle 1.2 (CCHS-1.2 dataset. Methods The CCHS-1.2 survey classified depression into lifetime depression and 12-month depression. The data were collected based on unequal sampling probabilities to ensure adequate representation of young persons (15 to 24 and seniors (65 and over. The sampling weights were used to estimate the prevalence of depression in each subgroup of the population. The multiple logistic regression technique was used to estimate the odds ratio of depression for each sociodemographic factor. Results The odds ratio of depression for men compared with women is about 0.60. The lowest and highest rates of depression are seen among people living with their married partners and divorced individuals, respectively. Prevalence of depression among people who live with common-law partners is similar to rates of depression among separated and divorced individuals. The lowest and highest rates of depression based on the level of education is seen among individuals with less than secondary school and those with "other post-secondary" education, respectively. Prevalence of 12-month and lifetime depression among individuals who were born in Canada is higher compared to Canadian residents who immigrated to Canada irrespective of gender. There is an inverse relation between income and the prevalence of depression (p Conclusion The patterns uncovered in this

There is evidence of heightened vulnerability to nonfatal suicidal behaviors among LGBT populations yet a paucity of studies into fatal behaviors. The specific aim of this article was to identify factors related to suicide in LGBT individuals in Australia. The psychological autopsy (PA) method with a matched case-control study design was used. PA interviews were conducted with 27 next-of-kin of an LGBT person that had died by suicide. Three living LGBT controls per suicide case, matched by age and gender, were also interviewed. The key factors relating to suicide in LGBT people were a lack of acceptance by family and self (reflected in higher internalized homophobia and shame), negative feelings about own sexuality/gender, and dissatisfaction with appearance. LGBT people who died by suicide also tended to go through coming out milestones 2 years earlier than controls. There was a higher prevalence of aggressive behaviors and a more predominant history of physical and sexual abuse. Additionally, there was greater incidence of depression and anxiety and alcohol and substance use disorders. Specific predictive factors for suicide in LGBT populations in Australia were identified, including significantly poorer mental health outcomes and more violence across an array of measures.

The 1974 amendments to the Labor Management Relations Act have created new problems of statutory interpretation in the rapidly evolving area of health care labor law. By including nonprofit hospitals under the auspices of the Act, the amendments have opened up a new area for unionization and have given rise to questions concerning the types of bargaining units that are appropriate in health care facilities. In the following article, the authors discuss these questions and other current issues in health care labor relations law. The issues include the determination of relevant bargaining units, the status of state nursing associations as labor organizations, and the ten-day strike notice requirement of the Labor Management Relations Act.
Full Text Available In this study, we propose a Bilateral Double Motive framework of stakeholder cooperation in complex projects. The framework analyses and explains dyadic promoter-stakeholder relationships at a micro level by acknowledging both transactional and relational motives. We demonstrate the framework’s usefulness by illustrating its explanatory power in two instances of cooperation and two of non-cooperation within two health information technology projects. The study contributes to project management theory through its combined focus on transactional and relational motives. Further, the study contributes to practice by providing a tool for planning and evaluating cooperation in health Information Technology projects and similar complex multi-stakeholder environments.

With abundant energy levels of 4f electron configurations, trivalent lanthanide ions (Ln3+) are endowed with unique and fascinating luminescent properties. Inheriting the native transition behaviour of the lanthanide ions, Ln3+ based nanomaterials have aroused great interest for a wide range of applications, including lighting and displays, optical fibers and amplifiers, responsive luminescent stains for biomedical analysis, in vivo and in vitro imaging, and enhancement for silicon solar cell devices. It should be noted that the application depends completely on the corresponding luminescent behaviour. To deepen the understanding of the luminescent mechanism is important for the developing of the field and the design of new Ln3+ based luminescent materials toward applications. In this review, we focused mainly on the recent developments on upconversion (UC) emission studies. Firstly, the emphasis was put on the introduction of basic luminescent properties of Ln3+ with f-f transitions, and then the corresponding mechanisms and properties of UC emission were discussed in detail, the potential researches with respect to UC mechanisms and properties were finally outlined.

Full Text Available Acute kidney injury (AKI is a serious problem during pregnancy. Once occurred, it brings about devastating maternal and fetal outcomes. Among developed nations, the trend of pregnancy-related AKI (PRAKI is on a decline due to the advances in obstetrics care and the legality of abortion. On the contrary, this situation remains one of the major health problems in the developing countries. Though some improvements have been observed, PRAKI still causes high maternal morbidity and mortality, leading to fetal losses. This article aims to review current studies with regards to obstetrics related AKI. Most of the studies in this review were carried out in observational, both prospective and retrospective, studies. Results demonstrated a variety of major PRAKI causes such as hypertensive disorders in pregnancy, obstetric hemorrhage, sepsis, thrombotic microangiopathy and acute fatty liver in pregnancy. Aside from awareness of the etiologies of PRAKI, understanding the physiological renal adaptation during pregnancy is crucial for early detection, diagnosis, and proper management to prevent the obstetric complications.

We present a way of teaching Einstein's special relativity. It starts with Galileo's relativity, the learners know from previous lectures. The lecture underlines that we can have three transformation equations for the space-time coordinates of the same event, which lead to absolute clock readings, time intervals and lengths (Galileo's relativity), to absolute clock readings but to relative time intervals and lengths (up-to-date Galileo transformations) and to relative clock readings time inte...

Improving a patient's ability to form and maintain satisfactory interpersonal relations is an important goal in many therapies. A mentalization-based approach to treatment is ideally suited to achieve this end to the extent it's designed to help improve a patient's ability to form more nuanced guesses about why others act as they do, based on a more accurate "read" of that individual's beliefs and desires. Interpersonal difficulties often issue when patients remain insistent on their own interpretation of another's motives that fly in the face of that individual's understanding of what is "driving" them. Helping patients explore the basis upon which they'd formed their conclusions about others goes a ways toward opening their mind to the possibility that things are a bit more complicated than first imaged. This in turn leads to greater curiosity and willingness to explore their own narratives and perceptions.

The purpose of this paper is to understand the influence of organizational factors on occupational accident causation. A field study was undertaken and focused on the phase of concreting the floors of a residential block in a building project in Brazil. The methodological approach was based on the analysis of carpenters' work practices and of the workers' accounts of minor falls. Observations were noted on work practices over this stage. Furthermore, interviews were conducted with the workers hired by the subcontractors and with professionals working for the main contractor. The results show that falls were related to the introduction of new building technology and its use by the workforce. The production planning and organization of activities by the subcontracted firms also led to temporary demands that were additional determining factors for falls on site. The work analysis reveals the need to consider organizational factors in prevention practices.

A biomarker can be a substance or structure measured in body parts, fluids or products that can affect or predict disease incidence. As age-related macular degeneration (AMD) is the leading cause of blindness in the developed world, much research and effort has been invested in the identification of different biomarkers to predict disease incidence, identify at risk individuals, elucidate causative pathophysiological etiologies, guide screening, monitoring and treatment parameters, and predict disease outcomes. To date, a host of genetic, environmental, proteomic, and cellular targets have been identified as both risk factors and potential biomarkers for AMD. Despite this, their use has been confined to research settings and has not yet crossed into the clinical arena. A greater understanding of these factors and their use as potential biomarkers for AMD can guide future research and clinical practice. This article will discuss known risk factors and novel, potential biomarkers of AMD in addition to their application in both academic and clinical settings. PMID:27156982

Alpha-1-antitrypsin deficiency (AATD) is an orphan disease that predisposes individuals to COPD and liver disease. The following is a comprehensive review of AATD from epidemiology to treatment for physicians who treat COPD or asthma. Areas covered: In this comprehensive review of alpha-1-antitrypsin deficiency, we describe the historical perspective, genetics, epidemiology, clinical presentation and symptoms, screening and diagnosis, and treatments of the condition. Expert commentary: The two most important directions for advancing the understanding of AATD involve improving detection of the condition, especially in asymptomatic patients, and advancing knowledge of treatments directed specifically at AATD-related conditions. With regard to treatment for AATD-related conditions, research must continue to explore the implications and importance of augmentation therapy as well as consider new implementations that may prove more successful taking into consideration not only factors of pulmonary function and liver health, but also product availability and financial viability.

Full Text Available Automobile drivers fine themselves affected by series psychological factors which are directly related to traffic accidents. In this study we intend to investigate these variables, basing our work on the most convenient sources of information, coming from the police, the General Direction of Traffic, the courts, insurance companies, the Red Cross, Social Security, and forensics. Neither could we ignore the influence which certain forces hold over people´s mental health; this can sometimes intensely affect how they drive. In fact, in the most diverse situations we can observe the way in which a person carries out a task can be conditioned by the presence of other person who may have no direct relationship to him. Society has established its limitations and rules, but speed itself feels omnipotence when imposing controls over the most profound behavior in others; man in usually not conscious of these controls. People generally drive their automobiles in a way similar to their habitual behavior and their personality traits. Nevertheless, it is also important to consider the adaptation of their way of driving to their state of mind at any given moment. The majority of subjects tend to adapt their driving to their emotional state.

Some patients are hesitant to disclose when they are experiencing pain. However, the reasons for this, such as stoicism and concern about being a bother to others, are poorly understood. If patient pain goes unrecognized during clinical encounters, patients may also be at greater risk for pain-related crises, use of hospice/palliative care on-call services, and in-patient transfers. This is an evidence-informed development of a practice-oriented conceptual model to understand and address patient reluctance to admit pain. We used a review of the available evidence to better understand the various factors that contribute to an unwillingness to disclose one's pain, create a conceptual model, and identify relevant assessment measures that may be useful to practitioners. Our review identified six primary attitudes and beliefs that contribute to patient reluctance to openly admit pain: (a) stigma; (b) stoicism; (c) cautiousness; (d) fatalism; (e) bother; and (f) denial. Four assessment measures that address elements of barriers to pain-related communication and four measures of nonverbal signs of pain were also identified and reviewed. Based on the model, social workers and other palliative care providers should consistently and vigilantly inquire about how comfortable patients are about discussing their own pain. Implications for practice and research are presented.

Due to increased demands for greater stringency in relation to hygiene and safety issues associated with fresh food products, coupled with ever-increasing demands by retailers for cost-effective extensions to product shelf-lives and the requirement to meet consumer expectations in relation to convenience and quality, the food packaging industry has rapidly developed to meet and satisfy expectations. One of the areas of research that has shown promise, and had success, is modified atmosphere packaging (MAP). The success of MAP-fresh meat depends on many factors including good initial product quality, good hygiene from the source plants, correct packaging material selection, the appropriate gas mix for the product, reliable packaging equipment, and maintenance of controlled temperatures and humidity levels. Advances in plastic materials and equipment have propelled advances in MAP, but other technological and logistical considerations are needed for successful MAP systems for raw chilled meat. Although several parameters critical for the quality of MA packed meat have been studied and each found to be crucial, understanding of the interactions between the parameters is needed. This review was undertaken to present the most comprehensive and current overview of the widely available, scattered information about the various integrated critical factors responsible for the quality and shelf life of MA packed meat with an interest to stimulate further research to optimize different quality parameters.

Soil Organic Carbon (SOC) constitutes the largest terrestrial carbon pool. The understanding of its dynamics and the environmental factors that influence its behaviour as sink or source of atmospheric CO 2 is crucial to quantify the carbon budget at the global scale. At the European scale, most of the existing studies to account for SOC stocks are centred in the fitting of predictive model to ascertain the distribution of SOC. However, the development of methodologies for monitoring and identifying the environmental factors that control SOC storage in Europe remains a key research challenge. Here we present a modelling procedure for mapping and monitoring SOC contents that uses Visible-Near Infrared (VNIR) spectroscopic measurements and a series of environmental covariates to ascertain the key environmental processes that have a major contribution into SOC sequestration processes. Our results show that it follows a geographically non-stationary process in which the influencing environmental factors have different weights depending on the spatial location. This implies that SOC stock modelling should not rely on a single model but on a combination of different statistical models depending on the environmental characteristics of each area. A cluster classification of European soils in relation to those factors resulted in the determination of four groups for which specific models have been obtained. Differences in climate, soil pH, content of coarse fragments or land cover type are the main factors explaining the differences in SOC in topsoil from Europe. We found that climatic conditions are the main driver of SOC storage at the continental scale, but we also found that parameters like land cover type influence SOC content found at the local scales in certain areas. Our methodology developed at continental scale could be used in future research aimed to improve the predictive performance of SOC assessments at European scale. Copyright © 2017 Elsevier B.V. All

Asthma is a leading cause of chronic disease-related school absenteeism. Few data exist on how information on absenteeism might be used to identify children for interventions to improve asthma control. This study investigated how asthma-related absenteeism was associated with asthma control, exacerbations, and associated modifiable risk factors using a sample of children from 35 states and the District of Columbia. The Behavioral Risk Factor Surveillance System Child Asthma Call-back Survey is a random-digit dial survey designed to assess the health and experiences of children aged 0-17 years with asthma. During 2014-2015, multivariate analyses were conducted using 2006-2010 data to compare children with and without asthma-related absenteeism with respect to clinical, environmental, and financial measures. These analyses controlled for sociodemographic and clinical characteristics. Compared with children without asthma-related absenteeism, children who missed any school because of asthma were more likely to have not well controlled or very poorly controlled asthma (prevalence ratio=1.50; 95% CI=1.34, 1.69) and visit an emergency department or urgent care center for asthma (prevalence ratio=3.27; 95% CI=2.44, 4.38). Mold in the home and cost as a barrier to asthma-related health care were also significantly associated with asthma-related absenteeism. Missing any school because of asthma is associated with suboptimal asthma control, urgent or emergent asthma-related healthcare utilization, mold in the home, and financial barriers to asthma-related health care. Further understanding of asthma-related absenteeism could establish how to most effectively use absenteeism information as a health status indicator. Published by Elsevier Inc.

Developmental precursors to children’s early understanding of gratitude were examined. A diverse group of 263 children were tested for emotion and mental state knowledge at ages 3 and 4, and their understanding of gratitude was measured at age 5. Children varied widely in their understanding of gratitude, but most understood some aspects of gratitude-eliciting situations. A model-building path analysis approach was used to examine longitudinal relations among early emotion and mental state knowledge and later understanding of gratitude. Children with a better early understanding of emotions and mental states understand more about gratitude. Mental state knowledge at age 4 mediated the relation between emotion knowledge at age 3 and gratitude understanding at age 5. The current study contributes to the scant literature on the early emergence of children’s understanding of gratitude. PMID:23331105

This commentary discusses the contributions of Drs. Antonia Abbey and Catherine Kaukinen to our understanding of risk factors for sexual and physical aggression among college students. Major contributions of their work are outlined. These include Abbey's contributions to our understanding of trajectories of sexually aggressive behavior among college men, risk factors for engaging in sexual aggression among men, and the role of alcohol in sexual aggression. In addition, Kaukinen's work has increased our understanding of the frequency of violence in college dating relationships as well as the association of violent relationships with health risk behaviors. Directions for future research are also outlined including a need to identify trajectories of violence risk as well as a need to understand the complex interrelationships among health risk behaviors and interpersonal violence. Finally, implications for practice and university policy are discussed, including a focus on the development of effective preventive strategies and proactive responses to violence. © The Author(s) 2014.

Self-efficacy beliefs that relate to teachers' motivation and performance have been an important area of concern for preservice teacher education. This study used a mixed-methods approach to investigate the changes in preservice elementary teachers' science self-efficacy beliefs and the factors associated in a specialized elementary physics content course. In addition, the study is one of few to investigate the relationship between the changes in science self-efficacy beliefs and changes in physical science conceptual understanding. Participants included fifty-one preservice elementary teachers enrolled in two term of the physical science content course. Data collection and analysis procedures included both qualitative and quantitative measures. Data collection included implementation of Science Teaching Efficacy Belief Instrument-B (STEBI-B) (Bleicher, 2004) and Physical Science Concept Test as pre- and post-test, two semi-structured interviews with 18 participants (nine each semester), classroom observations and artifacts. A pre-post, repeated measures multivariate analysis of variance (MANOVA) design was used to test the significance of differences between the pre- and post-surveys across time. Results indicated statistically significant gains in participants' science self-efficacy beliefs on both scales of STEBI-B - personal science teaching beliefs and outcome expectancy beliefs. Additionally, a positive moderate relationship between science conceptual understandings and personal science teaching efficacy beliefs was found. Post-hoc analysis of the STEBI-B data was used to select 18 participants for interviews. The participants belonged to each group representing the low, medium and high initial levels of self-efficacy beliefs. Participants' responses indicated positive shifts in their science teacher self-image and confidence to teach science in future. Four categories that represented the course-related factors contributing towards science self

Intercorrelation and regression analyses of data obtained from a drinking-related behavior and attitude household survey (N = 1127) of adults (age 18+) in Iowa are reported. The consumption variables were based on the 30 days prior to interview and included total ounces of absolute alcohol consumed; number of days the subject drank beer, wine and distilled spirits separately; typical quantity of each beverage consumed on drinking days; and the number of days drank five or more drinks within a couple of hours. The drinking attitude variables included level of tolerance (approve, indifferent, disapprove) of others' (men, women, spouse, son and daughter) drinking, getting high and getting intoxicated; a balance score of the proportion of positive and negative definitions of alcoholic beverages endorsed; an level of concern (not worried, somewhat worried and very worried) for eight possible consequences of heavy drinking. The drinking context variables used were the number of past 30 days that respondents drank at a bar or tavern, restaurant or club, home, others' homes, sports event and outdoor recreation; and number past 30 days drank alone, with relatives, work associates and close friends who are not work associates. The family environment variables included the respondent's report of whether any blood-related relatives had experienced alcohol-related problems, and of whether beverage alcohol was used in their childhood home.(ABSTRACT TRUNCATED AT 250 WORDS)

Cesarean section is the most frequent surgery done at health sector hospitals and its most frequent complications include hemorrhage. To determine if risk factors known for this complication are really a risk and to determine the reliability of the measurement of hematocrit and hemoglobin as parameters to quantify the hemorrhage. A prospective study involving 412 patients was done analyzing the following variables: age, previous cesarean section, occupation, body mass index, hours of labor, weight of the newborn, surgical time, bleeding estimated by the anesthesiologist, hemoglobin and hematocrit. By measuring hemoglobin a significant difference was obtained in favor of minor bleeding in the groups of 21 to 30 years, with normal weight and moderate obesity, with two prior cesarean sections, weight of the newborns of 3 to 4 kg, with less than two hours of labor, when the surgery took less than 50 minutes and when the bleeding was estimated at less than 500 mL. By measuring hematocrit the difference was significant in favor of more bleeding in the following groups: from 31 to 40 years, with mild obesity, without none or one cesarean section, with weight of newborns from 3 to 4 kg, with three to six hours of labor, when the cesarean section took 41 to 50 minutes and when the bleeding was estimated at less than 500 mL. There are significant differences with the measurement of hemoglobin and hematocrit among the risk factors analyzed.

Two studies examined children's developing understanding of Aesop's fables in relation to reading comprehension and to theory of mind. Study 1 included 172 children from Junior Kindergarten through Grade 6 in a school-wide examination of the relation between reading comprehension skills and understanding of Aesop's fables told orally. Study 2 examined the relation between theory of mind and fables understanding among 186 Junior (4-year-old) and Senior (5-year-old) Kindergarten children. Study 1 results showed a developmental progression in fables understanding with children's responses becoming increasingly decontextualized as they were able to extract the life lesson. After general vocabulary, passage comprehension predicted fables understanding. Study 2 results showed a relation between young children's theory of mind development and their understanding of fables. After general vocabulary, second-order theory of mind predicted children's fables understanding. Findings point to the importance of developing mental state awareness in children's ability to judge characters' intentions and to understand the deeper message embedded in fables.

Before talking about public understanding and public relations in the nuclear industry in Europe, a word about the mosaic structure of the European energy policy and public is required because a similar structure will be found in the European public understanding policy. Afterwards, we explain what communications tools are available and how the different European countries apply them.
Full Text Available Despite explosive growth in genomic datasets, the methods for studying epigenomic mechanisms of gene regulation remain primitive. Here we present a model-based approach to systematically analyze the epigenomic functions in modulating transcription factor-DNA binding. Based on the first principles of statistical mechanics, this model considers the interactions between epigenomic modifications and a cis-regulatory module, which contains multiple binding sites arranged in any configurations. We compiled a comprehensive epigenomic dataset in mouse embryonic stem (mES cells, including DNA methylation (MeDIP-seq and MRE-seq, DNA hydroxymethylation (5-hmC-seq, and histone modifications (ChIP-seq. We discovered correlations of transcription factors (TFs for specific combinations of epigenomic modifications, which we term epigenomic motifs. Epigenomic motifs explained why some TFs appeared to have different DNA binding motifs derived from in vivo (ChIP-seq and in vitro experiments. Theoretical analyses suggested that the epigenome can modulate transcriptional noise and boost the cooperativity of weak TF binding sites. ChIP-seq data suggested that epigenomic boost of binding affinities in weak TF binding sites can function in mES cells. We showed in theory that the epigenome should suppress the TF binding differences on SNP-containing binding sites in two people. Using personal data, we identified strong associations between H3K4me2/H3K9ac and the degree of personal differences in NFκB binding in SNP-containing binding sites, which may explain why some SNPs introduce much smaller personal variations on TF binding than other SNPs. In summary, this model presents a powerful approach to analyze the functions of epigenomic modifications. This model was implemented into an open source program APEG (Affinity Prediction by Epigenome and Genome, http://systemsbio.ucsd.edu/apeg.

Childbirth can represent for women the time of greatest vulnerability experience, often associated with being out of control, loneliness or sadness. One hundred and sixty women who had 'normal' births were assessed within 48 hours on potential predictive measures and at 3-6 months post-partum for PTSD. Symptoms of depression, anxiety, perceived and desired support by family members, friends, medical personnel were also assessed. t-Test and chi-square were used to analyze, differences between 'risk group' and 'non-risk group'. Few women (1.25%) showed questionnaire responses suggesting clinically significant levels on PTSD; other women (28.75%) reported clinically significant symptoms for at least one subscale. Being at the first delivery experience, together with perceptions of low levels of support from family members and medical personnel, were found to be related to experience of post-traumatic stress symptoms. Anxiety for the child and previous depression are also related to such symptoms. Moreover, anxiety and depression are related to a difficult recognition of the support received, as well as to the desire for more support, in the care of the newborn, from medical professionals.

The purpose of this study was to identify factors impacting students' ability to develop understanding of evolutionary theory. A novel approach to worldview theory was employed according to which individuals are seen as having one worldview that is comprised of many perspectives. One's worldview is comprised of numerous worldview assumptions, some of which coalesce to form worldview perspectives. Some assumptions are consistent with a scientific perspective while others are more consistent with a religious perspective. Scientific and religious perspectives were quantified based on participants' agreement with assumptions associated with each perspective. Participants completed a 103-item questionnaire addressing several variables: understanding of evolution, understanding of photosynthesis (non-confounding variable), strength of worldview perspectives and exposure to factors influencing the development of worldview perspectives. Increased exposure to factors influencing the development of a strong scientific worldview perspective was hypothesized to cause an increased understanding of evolution. The dependent variable understanding was measured by scores on two Likert-type measures. A causal-comparative study was conducted with 13 high school biology teachers and 67 high school biology students. To determine causation t-tests compared the mean scores on the variables measured. Extreme-group methods were used and data was analyzed for statistical differences between mean scores. Strong scientific worldview perspectives (t=1.003, p=3.19) and exposure to scientific factors (t=2.373, p=.02) were associated with a higher understanding of evolution. Strong religious worldview perspectives (t=-1.991, p=.05) and exposure to religious factors (t=-1.059, p=.31) were associated with a lower understanding of evolution. The results suggest that scientific worldview perspectives play an important role in increasing understanding of evolution; however, religious worldview

Achieving false belief understanding is an important cognitive milestone that allows children to understand that thoughts and reality can differ. Researchers have found that low-income children score significantly lower than middle-income children on false belief understanding but have not examined why this difference exists. We hypothesized that children's language and parent discipline mediate the income-false belief relation. Participants were 174 3- to 6-year-olds. False belief understanding was significantly correlated with family income, children's vocabulary, parents' self-reported discussion of children's behavior, discussion of emotions, and power assertion. Family income had a significant indirect effect on false belief understanding through children's vocabulary and parent discipline when examined independently, but only through children's vocabulary when using parallel multiple mediation. This study contributes to our knowledge of individual differences in false belief understanding. Copyright © 2017 Elsevier Inc. All rights reserved.

Early adolescence (ages 10-14) is a period of increased expectations for boys and girls to adhere to socially constructed and often stereotypical norms that perpetuate gender inequalities. The endorsement of such gender norms is closely linked to poor adolescent sexual and reproductive and other health-related outcomes yet little is known about the factors that influence young adolescents' personal gender attitudes. To explore factors that shape gender attitudes in early adolescence across different cultural settings globally. A mixed-methods systematic review was conducted of the peer-reviewed literature in 12 databases from 1984-2014. Four reviewers screened the titles and abstracts of articles and reviewed full text articles in duplicate. Data extraction and quality assessments were conducted using standardized templates by study design. Thematic analysis was used to synthesize quantitative and qualitative data organized by the social-ecological framework (individual, interpersonal and community/societal-level factors influencing gender attitudes). Eighty-two studies (46 quantitative, 31 qualitative, 5 mixed-methods) spanning 29 countries were included. Ninety percent of studies were from North America or Western Europe. The review findings indicate that young adolescents, across cultural settings, commonly express stereotypical or inequitable gender attitudes, and such attitudes appear to vary by individual sociodemographic characteristics (sex, race/ethnicity and immigration, social class, and age). Findings highlight that interpersonal influences (family and peers) are central influences on young adolescents' construction of gender attitudes, and these gender socialization processes differ for boys and girls. The role of community factors (e.g. media) is less clear though there is some evidence that schools may reinforce stereotypical gender attitudes among young adolescents.

To identify maternal and neonatal factors associated with prematurity in the municipality of Porto Alegre. This was a population-based case-control study. The cases were newborns under 37 weeks of gestation and the controls were newborns over 37 weeks. The data came from the records of 19,457 births in the city of Porto Alegre in the year 2012 from the Information System on Live Births of the Municipal Health Department. The analysis was carried outand adjusted by a Logistic Regression according to a hierarchical model. The variables studied were allocated into three hierarchy levels: sociodemographic variables; reproductive history; and gestational and birth factors. There were 767 cases allocated and 1,534 controls in a design of a case for two controls (1:2) by simple randomization. In the final model, a statistically significant association was found for prematurity for the following variables: mother's age under 19 years old (OR=1.32; CI 95%: 1.02-1.71) or over 34 years old (OR=1.39; CI 95%: 1.12-1.72); inadequate maternal schooling for age (OR=2.11; CI 95%: 1.22-3.65); multiple pregnancies (OR=1.14; CI 95%: 1.01-1.29); C-section (OR=1.15; CI 95%: 1.03-1.29); birth weights under 2,500g (OR=4.04; CI 95%: 3.64-4.49); Apgar score at five minutes between zero and three (OR=1.47; CI 95%: 1.12-1.91); and inadequate prenatal care (OR=1.18; CI 95%: 1.02-1.36). The present study showed the most immediate consequence of prematurity for newborns by evidencing its association with worse Apgar scores and low birth weight. The following factors were also shown as possible more distal determinants of prematurity: mother's age; inadequate maternal education; multiple gestation; inadequate prenatal care; and C-section.

Full Text Available A type of heritable cellular change, known as habituation, occurs spontaneously in plant tissue and cell culture. It is the acquired ability of a population of cells to grow and divide independently of exogenously supplied growth regulators. An imbalance in phytohormones in the media, particularly auxins and cytokinins, is an important source of stress and has been linked to hyperhydricity, somaclonal variation, recalcitrance and habituation. All of these abnormalities are potentially very costly to the plant breeding industry. Moreover, habituation as a tumorous and/or neoplastic transformation state that is interchangeable with a normal state in plant cell. This requires a better understanding of factors that contribute to these phenomena. Here we used a computational prediction method based on the known protein structural interactions to analyze grapevine large-scale protein-protein interaction rules within and among complete genomes such as yeast, fly, worm, Arabidopsis, and human and their HTP (high-throughput method maps. These studies may help to elucidate the molecular mechanisms of neoplastic phenomena in plants and perhaps in animals. We found fundamental differences among eukaryotic interactomes. We confirmed that all the predicted protein family interactomes (the full set of protein family interactions within a proteome of 6 species are scale-free networks, and they share a small core network comprising 16 protein families related to indispensable cellular functions involved predominantly in the pathogenesis, apoptosis and plant tumorigenesis, as well. Molecular evidence is presented that suggests that grapevine cells that have become habituated for one or more essential factors results from heritable alterations in the pattern of gene expression and that it can, therefore, be used as a model for study of cell differentiation. Moreover, the overall significance of these findings to the plant and in a some instantion also the animal

The present paper is aimed at briefly presenting psychological factors involved in cancer related pain and what psychosocial interventions are efficient in reducing it. Cancer related pain is a complex experience and the most integrative and recommended approach is the biopsychosocial model. It has been proved that chronic pain is more strongly related to psychological factors than to treatment or illness related factors. Psychological factors influencing pain experience can be intuitively grouped starting with awareness of pain (i.e., attentional factor), then with evaluation of pain (i.e., cognitive factors) which is leading to feelings (i.e., emotional factors), and behaviours (i.e., coping strategies) regarding pain. Psychosocial interventions (i.e., skill based and education based interventions) have strong evidence that is effective in reducing cancer related pain.

Leadership is one of the most examined factors in relation to understanding employee wellbeing and performance. While there are disparate approaches to studying leadership, they share a common assumption that perceptions of a leader's behavior determine reactions to the leader. The concept of leadership perception is poorly understood in most theoretical approaches. To address this, we propose that there are many benefits from examining leadership perceptions as an attitude towards the leader...

In this chapter, we review evidence from the human factors literature that verbal and visual formats can help increase the understanding of numerical risk information in health care. These visual representations of risk are grounded in empirically supported theory. As background, we first review research showing that people often have difficulty understanding numerical risks and benefits in health information. In particular, we discuss how understanding the meanings of numbers results in healthier decisions. Then, we discuss the processes that determine how communication of numerical risks can enhance (or degrade) health judgments and decisions. Specifically, we examine two different approaches to risk communication: a traditional approach and fuzzy-trace theory. Applying research on the complications of understanding and communicating risks, we then highlight how different visual representations are best suited to communicating different risk messages (i.e., their gist). In particular, we review verbal and visual messages that highlight gist representations that can better communicate health information and improve informed decision making. This discussion is informed by human factors theories and methods, which involve the study of how to maximize the interaction between humans and the tools they use. Finally, we present implications and recommendations for future research on human factors in health care. PMID:24999307

To understand the factors that facilitate career success for career development awardees in clinical and translational science and reconceptualize understand ing of career success for this population. In 2013-2014, the authors conducted semistructured interviews with former NIH KL2 or K12 scholars from nine Clinical and Translational Science Award-funded institutions. Participants either had or had not secured independent funding at least two years after the end of their last K award. Questions covered the factors that facilitate or hinder junior investigators' transition to independent funding. Interviews were recorded and transcribed, and the transcripts were analyzed thematically. Forty individuals participated, with equal representation by men and women and by independently and not independently funded investigators. Personal factors that facilitated success included networks, persistence and resilience, initiative, autonomy, and personal and professional balance. Organizational factors included appropriate mentorship, protected research time, and institutional resources and support.Even independently funded participants described challenges regarding career direction. Five participants without independent funding modeled a broad spectrum of successful career paths, having assumed leadership positions not reliant on grant funding. Alternative definitions of career success included improving public health, enjoying work, seeing mentees succeed, and receiving external acknowledgment of successes. Awareness of the factors that facilitate or hinder career success can help junior faculty, mentors, and institutional leaders support career development in clinical and translational science. New definitions of career success are needed, as are career paths for faculty who want to engage in research in roles other than principal investigator.

Full Text Available School leaders are a central factor of the quality of learning and teaching in schools. It is generally believed that the staff model their behaviour on leaders, which means if school leaders understand the physical school environment to be an important factor of learning, school staff (teachers and other professional staff will also do so. To discover how school leaders assess the school environment as a factor of learning, 150 school leaders in primary education in Slovenia were invited to complete an online questionnaire. They were asked about their views regarding to what extent their school as physical environment encouraged certain factors. Fourteen listed factors were assessed on five-point numeric scales. The results show that in their school environment, school leaders assessed ecology, movement, and respect the highest, and feelings, imagination, and space the lowest. Their estimates of the assessed factors differ depending on the type of school building (new, old, renovated only on the factors of movement, creativity, and logic and mathematics in favour of old schools. The results provide interesting information especially for school policy and everyone involved in the planning, building, or renewal of school premises.

Dementia of the Alzheimer's type (AD) is defined by both cognitive and functional decline; new criteria allow for identification of milder, non-functionally impaired patients. Understanding loss of autonomy in AD is essential, as later stages represent a significant burden and cost to patients, their families, and society. The purpose of the present analyses was to determine the factor structure of the Alzheimer's Disease Cooperative Study-Activities of Daily Living Scale (ADCS-ADL) in a cohort of AD patients. Baseline ADCS-ADL assessments of 734 AD patients from the PLASA study were included in an exploratory factor analysis (EFA). Because the ADCS-ADL was designed to assess change over time, change from baseline scores over 2 years were also analyzed using an EFA. Factorial solutions were evaluated based on cross-loading, non-loadings, and number of items per factor. Mean age at baseline was 79.3, mean MMSE was 19.8 and 73.3% of participants were female. Baseline data suggested a 4-factor solution that included factors for basic ADLs (BADLs), domestic/household activities, communication/engagement with the environment, and outside activities. The change scores EFA suggested a 2-factor solution of BADLs and instrumental ADLs (IADLs). Distinct factors of IADLs should be considered for further validation as areas of attention to catch early functional decline.

To understand the development of mathematical cognition and to improve instructional practices, it is critical to identify early predictors of difficulty in learning complex mathematical topics such as algebra. Recent work has shown that performance with fractions on a number line estimation task predicts algebra performance, whereas performance with whole numbers on similar estimation tasks does not. We sought to distinguish more specific precursors to algebra by measuring multiple aspects of knowledge about rational numbers. Because fractions are the first numbers that are relational expressions to which students are exposed, we investigated how understanding the relational bipartite format (a/b) of fractions might connect to later algebra performance. We presented middle school students with a battery of tests designed to measure relational understanding of fractions, procedural knowledge of fractions, and placement of fractions, decimals, and whole numbers onto number lines as well as algebra performance. Multiple regression analyses revealed that the best predictors of algebra performance were measures of relational fraction knowledge and ability to place decimals (not fractions or whole numbers) onto number lines. These findings suggest that at least two specific components of knowledge about rational numbers--relational understanding (best captured by fractions) and grasp of unidimensional magnitude (best captured by decimals)--can be linked to early success with algebraic expressions.

This study examined whether insecure attachment to each parent was associated with reduced emotion understanding in children and whether children showed consistent attachments to their mother and father. We measured children's attachment to each parent using the Manchester Child Attachment Story Task and child emotion understanding using the Test of Emotion Comprehension (children's M age = 5.64 years, SD = 0.84). The results indicated that insecure father-child attachment and insecure mother-child attachment were each associated with lower emotion understanding in children after controlling for parent's depressive symptoms and children's age. There was significant concordance of child attachment to mother and father. The findings provide support for convergence of children's attachment across parents and suggest that father-child attachment is an important factor to consider when examining children's emotion understanding. Statement of contribution What is already known on this subject Secure mother-child attachment is positively associated with children's emotional competence. Children form similar representations of attachment to their mother and father. What the present study adds Both mother-child and father-child attachment are associated with children's emotion understanding. The study's findings highlight the importance of father-child attachment in their children's emotion understanding. The study provides support for concordance of children's attachment across parents. © 2018 The British Psychological Society.

Climate models simulate a strong land-ocean contrast in the response of near-surface relative humidity to global warming: relative humidity tends to increase slightly over oceans but decrease substantially over land. Surface energy balance arguments have been used to understand the response over ocean but are difficult to apply over more complex land surfaces. Here, a conceptual box model is introduced, involving moisture transport between the land and ocean boundary layers and evapotranspira...

Conservative, non-antibiotic and non-surgical management of acute diverticulitis is currently being investigated. To better inform clinical decisions, better understanding of disease mechanisms, disease burden and severity is needed. Literature search of risk factors, pathophysiology, epidemiology and disease burden/severity reported over the last decade. Acute diverticulitis is a common disease and has a high disease burden. Incidence of hospital admissions is reported around 71 per 100,000 population, with reported increase in several subpopulations over the last decades. The incidence is likely to increase further with the aging populations. Risk factors for left-sided acute diverticulitis include dietary, anthropometric and lifestyle factors. Disease mechanisms are still poorly understood, but a distinction between inflammation and infection is emerging. The integrative and complex role of the gut microbiota has become an interesting factor for both understanding the disease as well as a potential target for intervention using probiotics. Mild, self-limiting events are increasingly reported from studies of successful non-antibiotic management in a considerable number of cases. Risk markers of progression to or presence of severe, complicated disease are needed for better disease stratification. Current risk stratification by clinical, imaging or endoscopic means is imperfect and needs validation. Long-term results from minimal-invasive and comparative surgical trials may better help inform clinicians and patients. Over- and under-treatment as well as over- and under-diagnosis of severity is likely to continue in clinical practice due to lack of reliable, robust and universal severity and classification systems. Better understanding of pathophysiology is needed.

The concept of the relative sensitivity factors required for the correction of the measured ion beam ratios in pin-cell glow discharge mass spectrometry is examined in detail. We propose a data-driven model for predicting the relative response factors, which relies on a non-linear least squares adjustment and analyte/matrix interchangeability phenomena. The model provides a self-consistent set of response factors for any analyte/matrix combination of any element that appears as either an analyte or matrix in at least one known response factor.

Aim of our study was to assess understanding of risks associated with intravascular application of contrast media in patients undergoing CT examination. We wanted to evaluate epidemiologic and socio-economic prognostic factors for a higher understanding of risks. Additionally, we evaluated a possible correlation between an extensive, outcome-oriented oral informed consent and better understanding of risks. 120 patients distributed in 2 study arms participated in this prospective study. In study arm I, the treating physician was not informed that his patients participated in a study whereas the physician in study arm II knew about the survey. After the informed consent we performed a standardized, semi-structured interview to enquire the 3 most frequent risks of intravascular application of contrast agents (anaphylactoid reactions, nephropathy and thyrotoxic crisis) and epidemiologic data. The understanding of the risks was evaluated using a 6 point scale. Patients scored 3.73 points in study arm I and 4.93 points in arm II on average. The statistical difference between both study arms was highly significant (p < 0.001). In a combined logistic regression analysis, only ''higher education'' (p = 0.001) and participation in study arm II (p =0.001) showed a significant connection to a better understanding of risks. Patients profit from an outcome-oriented and individualized informed consent. Due to the significant correlation between educational level and understanding of risks, informed consent should be adjusted to the educational status of the individual patient, e.g. by using didactic aids or individualized information sheets.

Few studies have explored young children's understanding of cancer and health-related behaviours yet this is essential to develop health promotion initiatives that build on young children's current knowledge levels and awareness. An exploratory descriptive design using the 'draw and write' technique was used to investigate children's views of cancer and health behaviours. The sample included 195 children aged eight to 11 years from five schools in deprived, affluent and rural locations in Scotland. When asked about cancer children demonstrated a good level of awareness by responding with text and drawings about the what they understood cancer to be; types of cancer; causes of cancer; what happens to people who have cancer; their personal experience of cancer and the emotions they associated with cancer. Older children, and children attending affluent schools, have more defined ideas about the causes of cancer and awareness of broader issues such as the risk of passive smoking or the potential impact on the family. Factors such as alcohol and illegal drugs were only reported by children attending schools in deprived locations. Children demonstrated considerable knowledge about healthy and unhealthy lifestyle behaviours; however, it is not clear whether this knowledge translates into their behaviours or the choices offered within their home environment. Children view cancer in a negative way from an early age, even without personal experience. There is a need to demystify cancer in terms of its causes, how to recognize it, how it is treated and to publicize improved survival rates. There is a need for targeted and developmentally appropriate approaches to be taken to health education in schools, with an awareness of the influence of the media on children's information. Strategies should take into consideration the socio-economic and cultural contexts of children's lives which influence their choices and behaviours. © 2010 Blackwell Publishing Ltd.

This article discusses how to deal with the relations between different cultural perspectives in classrooms, based on a proposal for considering understanding and knowledge as goals of science education, inspired by Dewey's naturalistic humanism. It thus combines educational and philosophical interests. In educational terms, our concerns relate to how science teachers position themselves in multicultural classrooms. In philosophical terms, we are interested in discussing the relations between belief, understanding, and knowledge under the light of Dewey's philosophy. We present a synthesis of Dewey's theory of inquiry through his naturalistic humanism and discuss its implications for the concepts of belief, understanding, and knowledge, as well as for the goals of science teaching. In particular, we highlight problems arising in the context of possible conflicts between scientific and religious claims in the school environment that result from totalitarian positions. We characterize an individual's position as totalitarian if he or she takes some way of thinking as the only one capable of expressing the truth about all that exists in the world, lacks open-mindedness to understand different interpretative perspectives, and attempts to impose her or his interpretation about the facts to others by violent means or not. From this stance, any other perspective is taken to be false a priori and, accordingly, as a putative target to be suppressed or adapted to the privileged way of thinking. We argue, instead, for a more fallibilist evaluation of our own beliefs and a more respectful appraisal of the diversity of students' beliefs by both students and teachers.

Implementing complex and multi-level public health programmes is challenging in school settings. Discrepancies between expected and actual programme outcomes are often reported. Such discrepancies are due to complex interactions between contextual factors. Contextual factors relate to the setting, the community, in which implementation occurs, the stakeholders involved, and the characteristics of the programme itself. This work uses realist evaluation to understand how contextual factors influence the implementation process, to result in variable programme outcomes. This study focuses on identifying contextual factors, pinpointing combinations of contextual factors, and understanding interactions and effects of such factors and combinations on programme outcomes on different levels of the implementation process. Schools which had participated in a school-based health promotion programme between 2012 and 2015 were included. Two sets of qualitative data were collected: semi-structured interviews with school staff and programme coordinators; and written documents about the actions implemented in a selection of four schools. Quantitative data included 1553 questionnaires targeting pupils aged 8 to 11 in 14 schools to describe the different school contexts. The comparison between what was expected from the programme (programme theory) and the outcomes identified in the field data, showed that some of the mechanisms expected to support the implementation of the programme, did not operate as anticipated (e.g. inclusion of training, initiation by decision-maker). Key factors which influenced the implementation process included, amongst other factors, the mode of introduction of the programme, home/school relationship, leadership of the management team, and the level of delegated power. Five types of interactions between contextual factors were put forward: enabling, hindering, neutral, counterbalancing and moderating effects. Recurrent combinations of factors were

To understand the influences and decisions of vulnerable older people in relation to keeping warm in winter. A qualitative study incorporating in-depth, semi-structured individual and group interviews, framework analysis and social marketing segmentation techniques. Rotherham, South Yorkshire, UK. 50 older people (>55) and 25 health and social care staff underwent individual interview. The older people also had household temperature measurements. 24 older people and 19 health and social care staff participated in one of the six group interviews. Multiple complex factors emerged to explain whether vulnerable older people were able to keep warm. These influences combined in various ways that meant older people were not able to or preferred not to access help or change home heating behaviour. Factors influencing behaviours and decisions relating to use of heating, spending money, accessing cheaper tariffs, accessing benefits or asking for help fell into three main categories. These were situational and contextual factors, attitudes and values, and barriers. Barriers included poor knowledge and awareness, technology, disjointed systems and the invisibility of fuel and fuel payment. Findings formed the basis of a social marketing segmentation model used to develop six pen portraits that illustrated how factors that conspire against older people being able to keep warm. The findings illustrate how and why vulnerable older people may be at risk of a cold home. The pen portraits provide an accessible vehicle and reflective tool to raise the capacity of the NHS in responding to their needs in line with the Cold Weather Plan.
Full Text Available Special theory of relativity is one of the difficult subjects of physics to be understood by the students. The current research designed as a qualitative research aim to determine the pre-service physics teachers’ understanding level and the alternative conceptions about three core concepts of special theory of relativity, such as time dilatation, length contraction and reference frames. The data were collected through semi structured interviews and were analyzed by using content analysis. At the end of the analysis process the understanding level of the students was determined to be “complete understanding”, “incomplete understanding” and “misunderstanding”. In order to achieve this, the students’ conceptual frameworks based on the operational definitions made by the students were determined firstly. The findings obtained in this research indicate that high school teachers as well as university instructors should take special care with some points in the teaching of the subjects related with special theory of relativity. This research might be useful to other studies to be done in the future, especially for investigating the students’ mental models related to special theory of relativity.

Time can be observed as a subjective, as well as an objective phenomenon which is a component of our life, and due to its communicational needs, it is standardized by temporal signs and symbols. The aim of this study was to determine the understanding of basic temporal relations of pupils with hearing impairments. We assumed that the knowledge of basic time relations is a precondition for the acquisition of knowledge that is connected with the understanding of the syllabus in regular school programs. Three groups of pupils have been examined: pupils with hearing impairments who attend the primary school of SUVAG Polyclinic under special condition, integrated hearing impaired pupils with minor additional difficulties who attend regular primary schools in Zagreb with a prolonged expert procedure and pupils of the control group. The subjects have been examined with a measuring instrument constructed by the expert team of the Polyclinic Suvag. Twenty nine subjects have been questioned, chronologically aged between 10 and 12.
Full Text Available The state-of-the-art in studies on mentalization suggests that capacity to understand other minds (mindreading, self introspection and consciousness, mental time travel in the past and the present, linguistic communication, are different components of a hierarchical organization of several functions reflecting the evolutionary development of the specie and integrates increasingly complex, mutually coordinated brain levels. The understanding of the precise hierarchical relations between them, that reflect the phylo- and ontogenetic evolutionary pathway for adaptation to the complex interpersonal and socio-cultural environment, has an essential application in psychopathology and psychotherapy, in particular for those clinical conditions where the normal integration of high order mental functions is hampered by developmental relational trauma.

Foreign-accented speech is generally harder to understand than native-accented speech. This difficulty is reduced for non-native listeners who share their first language with the non-native speaker. It is currently unclear, however, how non-native listeners deal with foreign-accented speech produced by speakers of a different language. We show that the process of (second) language acquisition is associated with an increase in the relative difficulty of processing foreign-accented speech. Therefore, experiencing greater relative difficulty with foreign-accented speech compared with native speech is a marker of language proficiency. These results contribute to our understanding of how phonological categories are acquired during second language learning. Copyright © 2016 Cognitive Science Society, Inc.
Full Text Available Ideally the product of tertiary informatic study is more than a qualification, it is a rewarding experience of learning in a discipline area. It should build a desire for a deeper understanding and lead to fruitful research both personally and for the benefit of the wider community. This paper asks: 'What are the factors that lead to this type of quality (deep learning in data analysis?' In the study reported in this paper, students whose general approach to learning was achieving or surface oriented adopted a deep approach when the context encouraged it. An overseas study found a decline in deep learning at this stage of a tertiary program; the contention of this paper is that the opposite of this expected outcome was achieved due to the enhanced learning environment. Though only 15.1% of students involved in this study were deep learners, the data analysis instructional context resulted in 38.8% of students achieving deep learning outcomes. Other factors discovered that contributed to deep learning outcomes were an increase in the intrinsic motivation of students to study the domain area; their prior knowledge of informatics; assessment that sought an integrated, developed yet comprehensive understanding of analytical concepts and processes; and, their learning preferences. The preferences of deep learning students are analyzed in comparison to another such study of professionals in informatics, examining commonalties and differences between this and the wider professional study.

Despite increased attention, conventional views of obesity are based upon individual behaviors, and children and parents living with obesity are assumed to be the primary problem solvers. Instead of focusing exclusively on individual reduction behaviors for childhood obesity, greater focus should be placed on better understanding existing community systems and their effects on obesity. The Milwaukee Childhood Obesity Prevention Project is a community-based coalition established to develop policy and environmental change strategies to impact childhood obesity in Milwaukee, Wisconsin. The coalition conducted a Group Model Building exercise to better understand root causes of childhood obesity in its community. Group Model Building is a process by which a group systematically engages in model construction to better understand the systems that are in place. It helps participants make their mental models explicit through a careful and consistent process to test assumptions. This process has 3 main components: (1) assembling a team of participants; (2) conducting a behavior-over-time graphs exercise; and (3) drawing the causal loop diagram exercise. The behavior-over-time graph portion produced 61 graphs in 10 categories. The causal loop diagram yielded 5 major themes and 7 subthemes. Factors that influence childhood obesity are varied, and it is important to recognize that no single solution exists. The perspectives from this exercise provided a means to create a process for dialogue and commitment by stakeholders and partnerships to build capacity for change within the community.

For a particular community, what energy-related innovations constitute no-regrets strategies? We present a methodology to understand how alternative energy consuming activities and policy regimes impact on current and future liveability of socio-culturally diverse communities facing climate change. Our methodology augments the energy policy literature by harnessing three concepts (collaborative governance, innovation and political economic regime of provisioning) to support dialogue around changing energy-related activities. We convened workshops in Alice Springs, Australia to build capability to identify no-regrets energy-related housing or transport activities and strategies. In preparation, we interviewed policy actors and constructed three new housing-related future scenarios. After discussing the scenarios, policy and research actors prioritised five socio-technical activities or strategies. Evaluations indicate participants enjoyed opportunities given by the methodology to have focussed discussions about activities and innovation, while requesting more socially nuanced scenario storylines. We discuss implications for theory and technique development. - Highlights: •Energy-related activities and regimes frustrate pro-sustainability action. •Participatory workshops increased understanding of activities and regimes. •Workshops used a novel combination of governance and social theories. •Results justify inclusive dialogue around building energy standards and transport options.

In order to protect medical students from burnout and its untoward psychiatric effects, it is imperative to understand their stress, burnout, coping, and resilience experiences. This study aimed to derive collective definitions from the medical student perspective, to identify common themes of students' experiences, and to distinguish pre-clinical and clinical year students' experiences relating to these four constructs. The authors conducted focus groups of medical students in Singapore across 4 years using a semi-structured question guide. Participants shared their understanding, experiences, and the relationships between stress, burnout, coping, and resilience. Coders independently evaluated construct definitions and derived common themes through an iterative process, and compared transcripts of pre-clinical and clinical year students to determine differences in experience over time. Nine focus groups (54 students, 28 females, mean age 24.3) were conducted. Students identified common definitions for each construct. Nine themes emerged within three domains: (1) relating constructs to personal experience, (2) interrelating stress, burnout, coping, and resilience, and (3) understanding the necessity of stress. Compared to clinical students, pre-clinical students reported theory-based rather than reality-based experiences and exam-induced stress, defined constructs using present rather than future situations, and described constructs as independent rather than interrelated. This sample of medical students in Singapore shares a common understanding of stress, burnout, coping, and resilience, but experiences these uniquely. They perceive a positive role for stress. These findings build upon prior literature, suggesting an interrelationship between stress and its related constructs and adding the novel perspective of students from an Asian country.

To explore the influential factors and strategies that promote an experienced nurse's intent to stay in their emergency or critical care area. Turnover among registered nurses (herein referred to as nurses) working in specialty areas of practice can result in a range of negative outcomes. The retention of specialty nurses at the unit level has important implications for hospital and health systems. These implications include lost knowledge and experience which may in turn impact staff performance levels, patient outcomes, hiring, orientating, development of clinical competence and other aspects of organizational performance. This qualitative study used an interpretive descriptive design to understand nurses' perceptions of the current factors and strategies that promote them staying in emergency or critical care settings for two or more years. Focus groups were conducted with 13 emergency and critical care nurses. Data analysis involved thematic analysis that evolved from codes to categories to themes. Four themes were identified: leadership, interprofessional relationships, job fit and practice environment. In addition, the ideas of feeling valued, respected and acknowledged were woven throughout. Factors often associated with nurse attrition such as burnout and job stresses were not emphasised by the respondents in our study as critical to their intent to stay in their area of practice. This study has highlighted positive aspects that motivate nurses to stay in their specialty areas. To ensure quality care for patients, retention of experienced emergency and critical care nurses is essential to maintaining specialty expertise in these practice settings. © 2017 John Wiley & Sons Ltd.

Traditional mental health models focus on psychological problems and distress; accordingly, health is viewed as the absence of illness or disability. In contrast, a dual-factor model of mental health incorporates both indicators of positive subjective well-being (SWB) and measures of psychopathological symptoms to comprehensively determine an individual's psychological adjustment. This study used such a dual-factor model to measure the mental health status of young adolescents. A total of 764 middle school students were classified into one of four distinct groups based on having high or low psychopathology and high or low SWB. Furthermore, group differences in student engagement, academic achievement, and environmental support for learning were investigated. Results demonstrated the existence of a traditionally neglected group of adolescents (low SWB and low psychopathology) who are nonetheless at risk for academic and behavior problems in school and who performed no better than the most troubled group of adolescents. Overall, both the presence of positive well-being and the absence of symptoms were necessary for ensuring the most advantageous school performance. These results highlight the importance of incorporating positive indicators of well-being along with traditional negative factors in more fully understanding relationships between individuals' mental health and educational outcomes. © 2010 American Orthopsychiatric Association.
Full Text Available While the synergies between research for knowledge discovery and teaching are widely accepted, the evidence is mostly implicit, verbal and poorly documented, and many times contradictive. In an effort to better understand the interaction between these important activities, the main objective of this study is to collect knowledge illustrating their synergies through specific cases. A complementary objective is to identify the important factors, which professionals should implement or avoid for increasing the likelihood that these synergies will be derived. To collect the necessary information personal interviews have been used to address the research question. The same set of questions was sent to several professionals known to have extensive experience in the areas of academic research and teaching. The respondents were asked to: 1. briefly describe the knowledge area in which the synergies occurred; 2. For the specified knowledge area, to please describe in summary form but specifically how they derived the synergy between research and teaching; and 3. Based on their personal experience, to please identify the important factors to increase the likelihood that academic research will produce benefits for teaching, and vice versa. The results strongly corroborate the importance of academic research for effective teaching. Based on the results, a set of recommendations are made to faculty members and school administrators to further promote academic research as an important factor for more effective teaching.
In recent times there has been an enormous interest in Vygotsky’s writing on conceptual development, particularly his insights on the differences between everyday and scientific thinking. In drawing upon cultural-historical theory, this paper seeks to examine the relations between everyday concepts and scientific concepts within playful contexts, such as preschools, with a view to better understanding how very young children develop conceptual understandings in science. This paper presents an overview of a study which sought to map the transformation and appropriation of scientific concepts within two early childhood settings. Approximately ten weeks of data gathering took place, with video recordings, field notes, photographic documentation, and child and teacher interviews for recording child concept formation within these naturalistic settings. The findings indicate that when teacher programs are more oriented towards concepts rather than materials, children’s play is focused on conceptual connections. Importantly, the study showed that: It was possible to map the multiple and dynamic levels or stratas of thinking that a child or group of children may exhibit within play-based contexts; An analysis of ‘unorganised heaps’ and ‘complexive thinking’ evident in conceptually or materially oriented play-based programs can be determined; the dialectical relations between everyday concepts and scientific concepts in play-based programs can be understood; and greater understanding about the nature of concept formation in situated playful contexts have been possible.

Understanding diet and energy balance as risk factors for breast, colon, and other cancers requires information on the contribution of each factor and of interactions among factors to cancer risk. Rodent models for breast cancer provide extensive data on effects of dietary fat and calories, energy balance, body weight gain, and physical activity on tumor development. Analyses of the combined data from many studies have shown clearly that quality and quantity of dietary fat and energy balance contribute independently to increased mammary gland tumorigenesis. These findings were seen in female rats fed diets high in fat (35-40% of calories) compared to rats fed control diets, with approximately 10% of calories as fat (Fay and Freedman, 1997, Breast Cancer Res. Treat. 46, 215-223). The methods used permit comparison of experimental and epidemiological data, and they may be useful in extrapolating between species and developing public health recommendations. In addition to the contributions of lifetime-diet composition, intake, energy balance, and physical activity to cancer risk, there are questions about the timing and duration of alterations in these factors and about the "dose-response" characteristics of cancer risk to the factors. Endocrine mechanisms may be significant in mammary gland tumor risk, but experimental and epidemiological data indicate that cancers at other sites, such as colon and liver, also are influenced by the factors listed. Other diet and lifestyle factors that influence energy, or specifically fat, metabolism may also affect risk for cancers that are promoted by increased intake of fat and calories. Studies of separate and interactive effects of dietary fat, black tea, weight gain, and mammary gland tumorigenesis (Rogers, et al, 1998, Carcinogenesis 19, 1269-1273) have been analyzed. Using adjustment of carcinogenesis endpoints for body weight, tumor burden, and latency, they were found to be related to weight gain within treatment groups in

Despite the known benefits of antenatal corticosteroids therapy its use in clinical practice is not generalized. To identify factors related to antenatal corticosteroids non administration. Cross-sectional and descriptive study that included patients admitted to Hospital Civil de Guadalajara "Dr. Juan I. Menchaca", who had indication for antenatal corticosteroids therapy but did not receive it. Variables: antenatal corticosteroids therapy prescription, factors related to antenatal corticosteroids therapy non administration and lapsed time between diagnosis and birth. Antenatal corticosteroids therapy were not prescribed in 79 (94%) of 84 patients. Main related factors were imminent birth and severe maternal complication. The longer amount of time from diagnosis to birth was before hospitalization (91 vs. 9%, p <0.0005). The biggest and best opportunity for the administration of inducers of fetal lung maturity is during prenatal care, when cases with increased risk of preterm birth are detected.
Full Text Available Private forests provide a range of ecosystem services for society including provisioning, regulating, cultural, and supporting services. Sustaining the supply of such services depends on the interest of nonindustrial private forest (NIPF landowners in managing their forests for such services. Assessing factors that influence NIPF landowner intentions would be useful in identifying potential suppliers of ecosystem services and in designing and implementing outreach and education programs to elevate the interests of less interested landowners. Using data collected from a mail survey of NIPF landowners on the Cumberland Plateau of Tennessee, this study examined how landowner interest in supplying ecosystem services was influenced by socio-demographic characteristics, economic and market factors, land management objectives, and ownership motivations. To that end, a multivariate logistic regression model was employed to analyze the supply of three types of ecosystem services: carbon storage (regulating service, water quality (provisioning service, and aesthetics (cultural service. Results revealed that landowner interest in managing forests for ecosystem services were significantly related to socio-demographic factors, management and ownership characteristics, and availability of financial incentives. These findings will improve the understanding of the market segment of landowners as related to ecosystem services. The findings may facilitate the development of market protocols and outreach programs that promote payments for ecosystem services in Tennessee and elsewhere.

Researchers have historically treated cognition and affect as separate constructs in motivating health behaviour. We present a framework and empirical evidence for complex relations between cognition and affect in predicting health behaviour. Main Outcome, Design and Results: First, affect and cognition can mediate each other's relation to health behaviour. Second, affect and cognition can moderate the other's impact. Third, context can change the interplay of affect and cognition. Fourth, affect and cognition may be indelibly fused in some psychological constructs (e.g. worry, anticipated regret and reactance). These four propositions in our framework are not mutually exclusive. Examination of the types of complex relations described here can benefit theory development, empirical testing of theories and intervention design. Doing so will advance the understanding of mechanisms involved in regulation of health behaviours and the effectiveness of interventions to change health behaviours.

This study identified job-related motivational factors among Malaysian employees in several telecommunication companies. Responses were obtained from 1,179 employees at all levels up to senior managers and six different functional divisions, sales and marketing, human resources, finance, technical, information, technology, and support division. All employees were asked to rate the importance of Kovach's 10 job-motivational factors. These factors were good wages, job security, opportunity for career growth in the organization, good working conditions, interesting work, company loyalty to employees, tactful discipline, full appreciation of work done, sympathetic help with personal problems, and feeling of being involved in the organization. The top five factors employees identified as motivating them in their jobs were good wages, job security, company loyalty to employees, good working conditions, and full appreciation for work done. Findings were in accordance with Kovach for U.S. employees, in which the top motivational factors were good wages and job security.

Respiratory syncytial virus (RSV) causes mild to severe respiratory illness in humans and is a major cause of hospitalizations of infants and the elderly. Both the innate and the adaptive immune responses contribute to the control of RSV infection, but despite successful viral clearance, protective immunity against RSV re-infection is usually suboptimal and infections recur. Poor understanding of the mechanisms limiting the induction of long-lasting immunity has delayed the development of an effective vaccine. The innate immune response plays a critical role in driving the development of adaptive immunity and is thus a crucial determinant of the infection outcome. Advances in recent years have improved our understanding of cellular and viral factors that influence the onset and quality of the innate immune response to RSV. These advances include the identification of a complex system of cellular sensors that mediate RSV detection and stimulate transcriptome changes that lead to virus control and the discovery that cell stress and apoptosis participate in the control of RSV infection. In addition, it was recently demonstrated that defective viral genomes (DVGs) generated during RSV replication are the primary inducers of the innate immune response. Newly discovered host pathways involved in the innate response to RSV, together with the potential generation of DVG-derived oligonucleotides, present various novel opportunities for the design of vaccine adjuvants able to induce a protective response against RSV and similar viruses.

Scientists have increasingly turned to the brain and to neuroscience more generally to further an understanding of social and emotional judgments and behavior. Yet, many neuroscientists (certainly not all) do not consider the role of relational context. Moreover, most have not examined the impact of relational context in a manner that takes advantage of conceptual and empirical advances in relationship science. Here we emphasize that: (1) all social behavior takes place, by definition, within the context of a relationship (even if that relationship is a new one with a stranger), and (2) relational context shapes not only social thoughts, feelings, and behaviors, but also some seemingly non-social thoughts, feelings, and behaviors in profound ways. We define relational context and suggest that accounting for it in the design and interpretation of neuroscience research is essential to the development of a coherent, generalizable neuroscience of social behavior. We make our case in two ways: (a) we describe some existing neuroscience research in three substantive areas (perceiving and reacting to others' emotions, providing help, and receiving help) that already has documented the powerful impact of relational context. (b) We describe some other neuroscience research from these same areas that has not taken relational context into account. Then, using findings from social and personality psychology, we make a case that different results almost certainly would have been found had the research been conducted in a different relational context. We neither attempt to review all evidence that relational context shapes neuroscience findings nor to put forward a theoretical analysis of all the ways relational context ought to shape neuroscience findings. Our goal is simply to urge greater and more systematic consideration of relational context in neuroscientific research.

Background Our aim was to describe the relationship between risk factors, such as stress, depression, and anxiety and potentially protective factors against pediatric headache-related disability, such as mindfulness, resilience, and self-compassion, and to determine teens’ interest in mind-body skills training to help reduce headache-related disability. Methods This was a cross-sectional survey among adolescents seen in an academic neurology clinic reporting four or more headaches monthly using standardized instruments to determine the relationship between putative risk and protective factors as well as physiologic markers of inflammation and vagal tone and headache-related disability. Results Among the 29 participants, 31% were male, the average age was 14.8 years, average headache frequency was 11.6 per month, and the most commonly reported trigger was stress (86%). The only risk or protective factor significantly associated with headache-related disability was depression (r=0.52, P=0.004). Depression was negatively correlated with mindfulness, resilience, and self-compassion (Pheadache-related disability or depression. There was strong interest in learning skills like slow, deep breathing practices supported by a smart phone app to reduce stress and the negative impact of headaches on daily life. Discussion Among teens with frequent migraine headaches, depression is the strongest risk factor for headache-related disability. Stress is viewed as a headache trigger, and teens reported wanting to learn simple stress management strategies supported by a smart phone application to help reduce headache-related disability.

Pre-migration and post-migration factors may influence the health of immigrants. Using a cross-national framework that considers the effects of the sending and receiving social contexts, we examined the extent to which pre-migration and post-migration factors, including individual and neighborhood level factors, influence depressive symptoms at a 2-year follow-up time point. Data come from the Boston Puerto Rican Health Study, a population-based prospective cohort of Puerto Ricans between the ages of 45 and 75 y. The association of neighborhood ethnic density with depressive symptomatology at follow-up was significantly modified by sex and level of language acculturation. Men, but not women, experienced protective effects of ethnic density. The interaction of neighborhood ethnic density with language acculturation had a non-linear effect on depressive symptomatology, with lowest depressive symptomatology in the second highest quartile of language acculturation, relative to the lowest and top two quartiles among residents of high ethnic density neighborhoods. Results from this study highlight the complexity, and interplay, of a number of factors that influence the health of immigrants, and emphasize the significance of moving beyond cultural variables to better understand why the health of some immigrant groups deteriorates at faster rates overtime.

Earthquakes, landslides, and tropical cyclones are extreme hazards that pose significant threats to human life and property. Some of the couplings between these hazards are well known. For example, sudden, widespread landsliding can be triggered by large earthquakes and by extreme rainfall events like tropical cyclones. Recent studies have also shown that earthquakes can be triggered by erosional unloading over 100-year timescales. In a NASA supported project, titled "Cascading hazards: Understanding triggering relations between wet tropical cyclones, landslides, and earthquake", we study triggering relations between these hazard types. The project focuses on such triggering relations in Taiwan, which is subjected to very wet tropical storms, landslides, and earthquakes. One example for such triggering relations is the 2009 Morakot typhoon, which was the wettest recorded typhoon in Taiwan (2850 mm of rain in 100 hours). The typhoon caused widespread flooding and triggered more than 20,000 landslides, including the devastating Hsiaolin landslide. Six months later, the same area was hit by the 2010 M=6.4 Jiashian earthquake near Kaohsiung city, which added to the infrastructure damage induced by the typhoon and the landslides. Preliminary analysis of temporal relations between main-shock earthquakes and the six wettest typhoons in Taiwan's past 50 years reveals similar temporal relations between M≥5 events and wet typhoons. Future work in the project will include remote sensing analysis of landsliding, seismic and geodetic monitoring of landslides, detection of microseismicity and tremor activities, and mechanical modeling of crustal stress changes due to surface unloading.

Although many studies have been published on the causes and mechanisms of chronic obstructive pulmonary disease (COPD), the reason for the existence of COPD and the reasons why COPD develops in humans have hardly been studied. Evolutionary medical approaches are required to explain not only the proximate factors, such as the causes and mechanisms of a disease, but the ultimate (evolutionary) factors as well, such as why the disease is present and why the disease develops in humans. According to the concepts of evolutionary medicine, disease susceptibility is acquired as a result of natural selection during the evolutionary process of traits linked to the genes involved in disease susceptibility. In this paper, we discuss the following six reasons why COPD develops in humans based on current evolutionary medical theories: (1) evolutionary constraints; (2) mismatch between environmental changes and evolution; (3) co-evolution with pathogenic microorganisms; (4) life history trade-off; (5) defenses and their costs, and (6) reproductive success at the expense of health. Our perspective pursues evolutionary answers to the fundamental question, 'Why are humans susceptible to this common disease, COPD, despite their long evolutionary history?' We believe that the perspectives offered by evolutionary medicine are essential for researchers to better understand the significance of their work.

Full Text Available This article aims to help expand our understanding of the armed conflicts and social tensions that exist in the Northeast of India, by examining the different levels at which conflict takes place, as well as by analysing some of the causes and factors involved in these contexts. To this end, the article is structured into three parts. In the first, the authors describe briefly the antecedents of the different conflicts and tensions, in order to establish a map of same and to contextualise them historically and socially. In the second part, five issues are analysed: armed conflicts as multifactorial realities that require examination in both regional and individual terms; the issue of demography as the constitutive factor of many discourses and accounts of the causes of disputes in the region; the Indian government’s responses to the conflicts; the role played by international regional actors and, finally, the dimension of gender in the conflicts. The third and final part includes some closing reflections, by way of a conclusion.

The study aimed to describe the medical, psychiatric, and cultural features of adolescent males with an eating disorder (ED). This retrospective evaluation took place at Hacettepe University, İhsan Doğramacı Children's Hospital, Ankara, Turkey, and covered a 4-year period between 2010 and 2013. Sixty adolescents were diagnosed with an ED during this period, 47 (78.3%) were females and 13 were males (21.7%) male. All 13 male patients who met full criteria for an ED according to the DSM criteria were included. Medical and psychiatric records of male patients treated for an ED were re-evaluated. The most striking finding of the study was that the female to male ratio became 3.6:1, with the increasing number of male adolescents with an ED. In our study, medical findings and complications of males with ED were similar to those seen in females. However, the most predominant gender difference was the co occurrence of a comorbid physical or mental illness. It is imperative to raise awareness of EDs in males. Although the medical findings of the study suggest that male and female adolescents with EDs are clinically similar to each other, the understanding of certain gender-specific risk factors shown in our study, such as a medical illness and/or obesity and co-morbid psychiatric diagnosis, are essential in raising suspicion. Further studies that especially evaluate cultural and social factors that affect parenting styles for boys are important in addessing possible risk factors for the development of EDs in males within different societies.
Full Text Available Gender relations have become a key dimension in family studies, and understanding gender relations as both determining and resulting from outcome of new family configurations requires the use of specific surveys aimed at the dynamics of couples. Unfortunately, nationally representative surveys of this type are not available for Latin American countries. Nonetheless, the most recent versions of the Demographic and Health Surveys (DHS include a section called "Women's Status and Empowerment", which can provide information about gender relations as well. This study aims at assessing the construct of gender relations in terms of couples' joint decision-making for all five Brazilian geographical regions. To this end, a step-by-step multi-group confirmatory factor analysis (MGCFA was applied in order to verify whether this concept can be compared across Brazilian regions. Results show that the DHS items can be used reliably for measuring couples' joint decision-making and that this construct can be meaningfully compared over the regions. These findings will contribute to further demographic and sociological research on gender relations which can use this concept and other indicators provided by the DHS to identify the causal processes related to it.

Full Text Available PURPOSE: To determine the relationship between the severity or stage of diabetic retinopathy and associated risk factors in a southern Brazilian population. METHODS: Transversal study of diabetic patients without previous ophthalmologic treatment, seen at a University eye clinic. These patients underwent fundus photography, complete blood work-up, systemic blood pressure measurement, urine analysis, and were questioned about risk factors previously determined by the authors. The presence or absence of risk factors was compared to the severity of diabetic retinopathy. RESULTS: Eighty-one patients were selected, 28 male, 53 female, 55 Caucasians, 26 African descendants, 28 had insulin-dependent diabetes mellitus, 53 had non-insulin-dependent diabetes mellitus. Factors related to more severe diabetic retinopathy include: insulin-dependent diabetes mellitus (a<0.01, nephropathy (a<0.05, proteinuria (a<0.05, duration of the disease (p<0.001, elevated fasting plasma glucose (p=0.11, glycosylated hemoglobin (HbA (1c (p=0.001, total serum cholesterol (p=0.019, lower hematocrit (p=0.004 and hemoglobin (p=0.001. CONCLUSIONS: The severity of diabetic retinopathy appears to be associated with risk factors such as duration of disease, type of diabetes, poor metabolic control, hemoglobin levels, total cholesterol and proteinuria. Factors apparently not related to severity of diabetic retinopathy include gender, age, systemic hypertension and hypomagnesemia.

Changes in the skin that occur in the elderly may put them at increased risk for altered percutaneous penetration from pharmacotherapy along with potential adverse effects. Skin factors that may have a role in age-related percutaneous penetration include blood flow, pH, skin thickness, hair and pore density, and the content and structure of proteins, glycosaminoglycans (GAGs), water, and lipids. Each factor is examined as a function of increasing age along with its potential impact on percutaneous penetration. Additionally, topical drugs that successfully overcome the barrier function of the skin can still fall victim to cutaneous metabolism, thereby producing metabolites that may have increased or decreased activity. This overview discusses the current data and highlights the importance of further studies to evaluate the impact of skin factors in age-related percutaneous penetration.

Estimates of picky eating are quite high among young children, with 14-50% of parents identifying their preschoolers as picky eaters. Dietary intake and preferences during the preschool years are characterized by slowing growth rates and children developing a sense of autonomy over their feeding and food selection. We argue that the current conceptualization of picky eating defines acts of resistance or expressions of preference (acts of autonomy) by a child as deviant behaviour. This conceptualization has guided research that uses a unidirectional, parent to child approach to understanding parent-child feeding interactions. By reviewing the current feeding literature and drawing parallels from the rich body of child socialization literature, we argue that there is a need to both re-examine the concept and parent/clinician perspectives on picky eating. Thus, the objective of this paper is two-fold: 1) We argue for a reconceptualization of picky eating whereby child agency is considered in terms of eating preferences rather than categorized as compliant or non-compliant behaviour, and 2) We advocate the use of bi-directional relational models of causality and appropriate methodology to understanding the parent-child feeding relationship. Researchers are often interested in understanding how members in the parent-child dyad affect one another. Although many tend to focus on the parent to child direction of these associations, findings from child socialization research suggest that influence is bidirectional and non-linear such that parents influence the actions and cognitions of children and children influence the actions and cognitions of parents. Bi-directional models of causality are needed to correctly understand parent-child feeding interactions. A reconceptualization of picky eating may elucidate the influence that parental feeding practices and child eating habits have on each other. This may allow health professionals to more effectively support parents in

We produce an explicit formula for the dispersion relation for the Dirac equation in the standard model extension in the presence of Lorentz violation. Our expression is obtained using novel techniques which exploit the algebra of quaternions. The dispersion relation is found to conveniently factor in two special cases that each involve a mutually exclusive set of nonvanishing Lorentz-violating parameters. This suggests that a useful approach to studies of Lorentz-violating models is to split the parameter space into two separate pieces, each of which yields a simple, tractable dispersion relation that can be used for analysis.

Facilitating human-carnivore coexistence depends on the biophysical environment but also on social factors. Focusing on Central Romania, we conducted 71 semi-structured interviews to explore human-bear (Ursus arctos) coexistence. Qualitative content and discourse analysis identified three socially mediated thematic strands, which showed different ways in which perceived interactions between people, bears and the environment shape coexistence. The "landscape-bear strand" described perceptions of the way in which the landscape offers resources for the bear, while the "landscape-human strand" related to ways in which humans experience the landscape. The "management strand" related to the way bears was managed. All three strands highlight both threats and opportunities for the peaceful coexistence of people and bears. Management and policy interventions could be improved by systematically considering the possible effects of interventions on each of the three strands shaping coexistence. Future research should explore the relevance of the identified thematic strands in other settings worldwide.

Full Text Available Abstract Treatment of idiopathic pulmonary fibrosis patients has evolved very slowly; the fundamental approach of corticosteroids alone or in combination with other immunosuppressive agents has had little impact on long-term survival. The continued use of corticosteroids is justified because of the lack of a more effective alternative. Current research indicates that the mechanisms driving idiopathic pulmonary fibrosis reflect abnormal, dysregulated wound healing within the lung, involving increased activity and possibly exaggerated responses by a spectrum of profibrogenic growth factors. An understanding of the roles of these growth factors, and the way in which they modulate events at cellular level, could lead to more targeted therapeutic strategies, improving patients' quality of life and survival.

This study examined preservice teachers' understanding of biotechnology and its related processes. A sample comprised 88 elementary education preservice teachers at a large university in the Midwest of the USA. A total of 60 and 28 of the participants were enrolled in introductory and advanced science methods courses, respectively. Most participants had taken two integrated science courses at the college level. Data were collected using a questionnaire, which had open-ended items and which required participants to write the definitions and examples of the following terms: biotechnology, genetic engineering, cloning and genetically modified foods. The results indicate that preservice teachers had limited understanding of biotechnology and its related processes. The majority of the preservice teachers provided poor definitions, explanations, and examples of biotechnology, genetic engineering and genetically modified foods. Surprisingly, however, a moderate number of preservice teachers correctly defined cloning and provided correct examples of cloning. Implications for science teacher education, science curriculum, as well as recommendations for further research are discussed. Copyright © 2011 Wiley Periodicals, Inc.

Background Funders of health research increasingly seek to understand how best to allocate resources in order to achieve maximum value from their funding. We built an international consortium and developed a multinational case study approach to assess benefits arising from health research. We used that to facilitate analysis of factors in the production of research that might be associated with translating research findings into wider impacts, and the complexities involved. Methods We built on the Payback Framework and expanded its application through conducting co-ordinated case studies on the payback from cardiovascular and stroke research in Australia, Canada and the United Kingdom. We selected a stratified random sample of projects from leading medical research funders. We devised a series of innovative steps to: minimize the effect of researcher bias; rate the level of impacts identified in the case studies; and interrogate case study narratives to identify factors that correlated with achieving high or low levels of impact. Results Twenty-nine detailed case studies produced many and diverse impacts. Over the 15 to 20 years examined, basic biomedical research has a greater impact than clinical research in terms of academic impacts such as knowledge production and research capacity building. Clinical research has greater levels of wider impact on health policies, practice, and generating health gains. There was no correlation between knowledge production and wider impacts. We identified various factors associated with high impact. Interaction between researchers and practitioners and the public is associated with achieving high academic impact and translation into wider impacts, as is basic research conducted with a clinical focus. Strategic thinking by clinical researchers, in terms of thinking through pathways by which research could potentially be translated into practice, is associated with high wider impact. Finally, we identified the complexity of
Full Text Available Much of the previous literature has studied the relationship between individual lifestyle factors and the health-related quality of life (HRQOL. However, only a few studies combined them to explore their relative importance to the HRQOL in the elderly. This study assesses the HRQOL of the urban, rural, and institutionalized Chinese elderly and explores the relative contributions of different lifestyle factors to their HRQOL. The SF-36v2 Health Survey, the WHOQOL-OLD module, and the socio-demographic and lifestyle questionnaire were utilized in this study. Hierarchical regression was performed in order to analyze the results. The physical and mental component scores of the SF-36v2 survey were 47.05 ± 9.95 and 54.92 ± 9.92, respectively. The total score for the WHOQOL-OLD module was 73.01 ± 11.99, with institutionalized persons reporting lower scores. For the physical component of the elderly participants’ HRQOL, the R2 value changed the most (0.116 when exercise-and-labor-related factors were added in. For the mental component, sleep-related (0.054, and leisure-time-activity-related factors (0.053 caused the largest change of the R2 value. For the elderly-specific HRQOL, measured by the WHOQOL-OLD module, the leisure-time-activity-related factors caused the largest change in the R2 value (0.119, followed by exercise-and-labor-related factors (0.078. Heterogeneity was present among the three subgroups. In sum, compared with their community-dwelling counterparts, the HRQOL of institutionalized older people was relatively poor and different lifestyle factors contributed to the HRQOL differently.

The risk factors for surgical site infections in surgery should be measured and monitored from admission to 30 days after the surgical procedure, because 30% of Surgical Site Infection is detected when the patient was discharged. Calculate the Relative Risk of associated factors to surgical site infections in adult with elective surgery. Patients were classified according to the surgery contamination degree; patient with surgery clean was defined as no exposed and patient with clean-contaminated or contaminated surgery was defined exposed. Risk factors for infection were classified as: inherent to the patient, pre-operative, intra-operative and post-operative. Statistical analysis; we realized Student t or Mann-Whitney U, chi square for Relative Risk (RR) and multivariate analysis by Cox proportional hazards. Were monitored up to 30 days after surgery 403 patients (59.8% women), 35 (8.7%) developed surgical site infections. The factors associated in multivariate analysis were: smoking, RR of 3.21, underweight 3.4 hand washing unsuitable techniques 4.61, transfusion during the procedure 3.22, contaminated surgery 60, and intensive care stay 8 to 14 days 11.64, permanence of 1 to 3 days 2.4 and use of catheter 1 to 3 days 2.27. To avoid all risk factors is almost impossible; therefore close monitoring of elective surgery patients can prevent infectious complications.
Full Text Available BACKGROUND: Occupational exposure to welding fumes is a serious occupational health problem all over the world. Welders are exposed to many occupational hazards; these hazards might cause some occupational diseases. The aim of the study was to assess the health related quality of life (HRQL of electric welders in Shanghai China and explore influencing factors to HRQL of welders. METHODS: 301 male welders (without pneumoconiosis and 305 non-dust male workers in Shanghai were enrolled in this study. Short Form-36 (SF-36 health survey questionnaires were applied in this cross-sectional study. Socio-demographic, working and health factors were also collected. Multiple stepwise regress analysis was used to identify significant factors related to the eight dimension scores. RESULTS: Six dimensions including role-physical (RP, bodily pain (BP, general health (GH, validity (VT, social function (SF, and mental health (MH were significantly worse in welders compared to non-dust workers. Multiple stepwise regress analysis results show that native place, monthly income, quantity of children, drinking, sleep time, welding type, use of personal protective equipment (PPE, great events in life, and some symptoms including dizziness, discomfort of cervical vertebra, low back pain, cough and insomnia may be influencing factors for HRQL of welders. Among these factors, only sleep time and the use of PPE were salutary. CONCLUSIONS: Some dimensions of HRQL of these welders have been affected. Enterprises which employ welders should take measures to protect the health of these people and improve their HRQL.

Neurobehavioral evidence supports the existence of at least two anatomically distinct "memory systems" in the mammalian brain that mediate dissociable types of learning and memory; a "cognitive" memory system dependent upon the hippocampus and a "stimulus-response/habit" memory system dependent upon the dorsolateral striatum. Several findings indicate that despite their anatomical and functional distinctiveness, hippocampal- and dorsolateral striatal-dependent memory systems may potentially interact and that, depending on the learning situation, this interaction may be cooperative or competitive. One approach to examining the neural mechanisms underlying these interactions is to consider how various factors influence the relative use of multiple memory systems. The present review examines several such factors, including information compatibility, temporal sequence of training, the visual sensory environment, reinforcement parameters, emotional arousal, and memory modulatory systems. Altering these parameters can lead to selective enhancements of either hippocampal-dependent or dorsolateral striatal-dependent memory, and bias animals toward the use of either cognitive or habit memory in dual-solution tasks that may be solved adequately with either memory system. In many learning situations, the influence of such experimental factors on the relative use of memory systems likely reflects a competitive interaction between the systems. Research examining how various factors influence the relative use of multiple memory systems may be a useful method for investigating how these systems interact with one another.

Full Text Available PURPOSES: To assess the risk factors of age-related macular degeneration in Argentina using a case-control study. METHODS: Surveys were used for subjects' antioxidant intake, age/gender, race, body mass index, hypertension, diabetes (and type of treatment, smoking, sunlight exposure, red meat consumption, fish consumption, presence of age-related macular degeneration and family history of age-related macular degeneration. Main effects models for logistic regression and ordinal logistic regression were used to analyze the results. RESULTS: There were 175 cases and 175 controls with a mean age of 75.4 years and 75.5 years, respectively, of whom 236 (67.4% were female. Of the cases with age-related macular degeneration, 159 (45.4% had age-related macular degeneration in their left eyes, 154 (44.0% in their right eyes, and 138 (39.4% in both eyes. Of the cases with age-related macular degeneration in their left eyes, 47.8% had the dry type, 40.3% had the wet type, and the type was unknown for 11.9%. The comparable figures for right eyes were: 51.9%, 34.4%, and 13.7%, respectively. The main effects model was dominated by higher sunlight exposure (OR [odds ratio]: 3.3 and a family history of age-related macular degeneration (OR: 4.3. Other factors included hypertension (OR: 2.1, smoking (OR: 2.2, and being of the Mestizo race, which lowered the risk of age-related macular degeneration (OR: 0.40. Red meat/fish consumption, body mass index, and iris color did not have an effect. Higher age was associated with progression to more severe age-related macular degeneration. CONCLUSION: Sunlight exposure, family history of age-related macular degeneration, and an older age were the significant risk factors. There may be other variables, as the risk was not explained very well by the existing factors. A larger sample may produce different and better results.
Full Text Available The purpose of this study is to identify factors related to the closing of 50 ETFs in 2008. The study compared the sample of liquidated ETFs to a matched sample of active ETFs. The factors used as explanatory variables were: market capitalization, liquidity, ETF return, Index return, tracking error, fund age, and premium. Lower liquidity values, higher tracking errors, and higher ETF returns were associated with higher probabilities of liquidation. The researcher found evidence that ETFs’ market makers were profiting from the creation of new ETFs’ shares just before liquidating the ETFs’ shares at a premium.
Little is known about how actual use of Internet health-related information is associated with health or health-related behavior. Using a nationally representative sample of 34,525 from 2012, this study examined the demographics of users of Internet health-related information (users), reports estimates of association with several health and behavioral outcomes adjusting for demographic factors, and analyzed the sample by education level, race, gender, and age. Analysis of a large nationally representative sample shows evidence that users of health-related information (users) on the Internet are younger, more educated, more likely to be insured, more likely to be female, and less likely to be African American. After adjusting for demographic differences, users are more likely to have been diagnosed with hypertension, cancer, stroke, and high cholesterol, but no evidence of current hypertension, weight-related issues, or being in fair or poor health. Users are less likely to smoke and among smokers are more likely to attempt quitting. Users are more likely to exercise, get a flu shot, pap smear, mammogram, HIV test, colon cancer screening, blood pressure check, and cholesterol check, but likely to be heavy drinkers. With few exceptions, results appear robust across gender, age groups, level of education, and ethnicity. Use is generally positively associated with prior diagnosis for several conditions and behaviors related to improved health, but I find no relationship with existing health status. The association between use of health-related Internet information and health-related behavior seems robust across levels of education, age, gender, and race.

The purposes of this study were to investigate the level and distribution of job satisfaction and to explore work environment factors associated with job satisfaction of South Korean dentists. A stratified systematic random sample of 1029 dentists was selected from the 10 357 registered dentists in the Korean Dental Association. They were surveyed via a self-administered mail questionnaire. Job satisfaction was measured by a modified version of the Dentist Satisfaction Survey. The response rate was 62.2%. The mean score of overall job satisfaction among South Korean dentists was 3.2 out of 5. In terms of work environment factors, the most satisfying aspect was patient relations (3.7) and the least satisfying aspect was personal time (2.8). Multiple regression analysis identified a model including patient relations, perception of income, personal time, staff, and specialty training that accounted for 35% of variation in overall job satisfaction. The majority of the variance was explained by patient relations. This study suggests that patient relations, perception of income, personal time, staff, and specialty training are important work environment factors for job satisfaction among South Korean dentists. The findings of this study will be helpful to policy makers to design plans to increase the level of job satisfaction among South Korean dentists.

to obtain survival rate and mortality-related factors of malignant obstructive jaundice patients. all medical records of obstructive jaundice inpatient at Cipto Mangunkusumo Hospital, Jakarta from January 2010 to December 2013 were reviewed retrospectively. The following factors were analyzed in terms of mortality: age, gender, sepsis, hypoalbumin, serum bilirubin level, serum CA 19-9 level, billiary drainage, non-ampulla Vateri carcinoma, and comorbid factors. total 181 out of 402 patients were enrolled in this study with male proportion was 58.6%, and patients aged 50 years or above was 57.5%. Multivariate analysis showed that only sepsis, unsuccessful or no prior biliary drainage and Charlson comorbid score ≥4 were independent predictors of mortality. Patients with significant prognostic factors had median survival 14 days compared with overall median survival 26 days. Score ≥2 identified as the highest prognostic score threshold with sensitivity 68%, specificity 75%, and AUC on ROC curve 0.769. sepsis, unsuccessful or no prior bilirary drainage, and Charlson comorbid score ≥4 are factors significantly associated with shortened survival in malignant obstructive jaundice patients. Prognostic score ≥2 was determined to classify patients into high risk mortality group. Mortality of patients with those significant prognostic factors can be predicted in 76.9%.
Full Text Available Background. Peritonitis represents a major complication of peritoneal dialysis (PD. The aim of this paper was to systematically collect data on patient-related risk factors for PD-associated peritonitis, to analyze the methodological quality of these studies, and to summarize published evidence on the particular risk factors. Methods. Studies were identified by searches of Pubmed (1990–2012 and assessed for methodological quality by using a modified form of the STROBE criteria. Results. Thirty-five methodologically acceptable studies were identified. The following nonmodifiable risk factors were considered valid and were associated with an increased risk of peritonitis: ethnicity, female gender, chronic lung disease, coronary artery disease, congestive heart failure, cardiovascular disease, hypertension, antihepatitis C virus antibody positivity, diabetes mellitus, lupus nephritis or glomerulonephritis as underlying renal disease, and no residual renal function. We also identified the following modifiable, valid risk factors for peritonitis: malnutrition, overweight, smoking, immunosuppression, no use of oral active vitamin D, psychosocial factors, low socioeconomic status, PD against patient’s choice, and haemodialysis as former modality. Discussion. Modifiable and nonmodifiable risk factors analyzed in this paper might serve as a basis to improve patient care in peritoneal dialysis.

Diet is an important factor related to the development of numerous diseases. In developing countries like Ecuador, this aspect is not considered as priority however, the study of the incidence of certain diet-related diseases could help to assess consumption habits of a country from a Public Health perspective and support national nutrition policies and programs. The objective the present study is to investigate the mortality rate of certain diet-related diseases in Ecuador and its possible relationship with Ecuadorian consumption habits. For that, mortality rates (2001-2008) associated with five different disease groups related to dietary factors (cancer of colon, cerebrovascular diseases, cardiovascular diseases, diabetes mellitus and liver diseases) were collected, analyzed and compared to consumption patterns in Ecuador. According to results, Ecuador has a low level of cancer of colon in comparison with developed countries (e.g. Spain). The group with the highest number of deaths corresponded to cardiovascular diseases followed by cerebrovascular diseases. The mortality study per province revealed that Amazonian provinces showed few deaths in relation to other provinces in Ecuador. This could be due to different factors including fails in the disease surveillance information systems, environmental factors and consumption patterns. In this sense, further investigation on native products consumption such as "chontaduro" might help to find valuable foods contributing to healthier Ecuadorian diet. These results, though preliminary, evidence that a major effort should be made by national and international organisations to collect data on consumption patterns and nutritional aspects of the Ecuadorian population in order to better support the development of effective food security and nutrition policies.

Health and related claims on food labels can support consumer education initiatives that encourage purchase of healthier foods. A new food Standard on Nutrition, Health and Related Claims became law in January 2013. Implementation will need careful monitoring and enforcement to ensure that claims are truthful and have meaning. The current study explored factors that may impact on environmental health officers' food labelling policy enforcement practices. The study used a mixed-methods approach, using two previously validated quantitative questionnaire instruments that provided measures of the level of control that the officers exercised over their work, as well as qualitative, semi-structured, in-depth interviews. Local government; Australia. Thirty-seven officers in three Australian states participated in semi-structured in-depth interviews, as well as completing the quantitative questionnaires. Senior and junior officers, including field officers, participated in the study. The officers reported a high level of autonomy and control of their work, but also a heavy workload, dominated by concerns for public health and food safety, with limited time for monitoring food labels. Compliance of labels with proposed health claims regulations was not considered a priority. Lipsky's theory of street-level bureaucracy was used to enhance understanding of officers' work practices. Competing priorities affect environmental health officers' monitoring and enforcement of regulations. Understanding officers' work practices and their perceptions of enforcement is important to increase effectiveness of policy implementation and hence its capacity to augment education initiatives to optimize health benefits.

The Earth's climate system includes complex behavior and interconnections with other Earth spheres that present challenges to student learning. To better understand these unique challenges, we have conducted experiments with high-school and introductory level college students to determine how information pertaining to the connections between the Earth's atmospheric system and the other Earth spheres (e.g., hydrosphere and cryosphere) are processed. Specifically, we include psychomotor tests (e.g., eye-tracking) and open-ended questionnaires in this research study, where participants were provided scientific images of the Earth (e.g., global precipitation and ocean and atmospheric currents), eye-tracked, and asked to provide causal or relational explanations about the viewed images. In addition, the students engaged in on-line modules (http://serc.carleton.edu/eslabs/climate/index.html) focused on Earth system science as training activities to address potential cognitive barriers. The developed modules included interactive media, hands-on lessons, links to outside resources, and formative assessment questions to promote a supportive and data-rich learning environment. Student eye movements were tracked during engagement with the materials to determine the role of perception and attention on understanding. Students also completed a conceptual questionnaire pre-post to determine if these on-line curriculum materials assisted in their development of connections between Earth's atmospheric system and the other Earth systems. The pre-post results of students' thinking about climate change concepts, as well as eye-tracking results, will be presented.

Research on ethical dilemmas in health care has become increasingly salient during the last two decades resulting in confusion about the concept of moral distress. The aim of the present paper is to provide an overview and a comparative analysis of the theoretical understandings of moral distress and related concepts. The focus is on five concepts: moral distress, moral stress, stress of conscience, moral sensitivity and ethical climate. It is suggested that moral distress connects mainly to a psychological perspective; stress of conscience more to a theological-philosophical standpoint; and moral stress mostly to a physiological perspective. Further analysis indicates that these thoughts can be linked to the concepts of moral sensitivity and ethical climate through a relationship to moral agency. Moral agency comprises a moral awareness of moral problems and moral responsibility for others. It is suggested that moral distress may serve as a positive catalyst in exercising moral agency. An interdisciplinary approach in research and practice broadens our understanding of moral distress and its impact on health care personnel and patient care.

Does the comprehension of both action-related and abstract verbs rely on motor simulation? In a behavioral experiment, in which a semantic task was used, response times to hand-action-related verbs were briefer than those to abstract verbs and both decreased with repetition of presentation. In a transcranial magnetic stimulation (TMS) experiment, single-pulse stimulation was randomly delivered over hand motor area of the left primary motor cortex to measure cortical-spinal excitability at 300 or 500 ms after verb presentation. Two blocks of trials were run. In each block, the same verbs were randomly presented. In the first block, stimulation induced an increase in motor evoked potentials only when TMS was applied 300 ms after action-related verb presentation. In the second block, no modulation of motor cortex was found according to type of verb and stimulation-delay. These results confirm that motor simulation can be used to understand action rather than abstract verbs. Moreover, they suggest that with repetition, the semantic processing for action verbs does not require activation of primary motor cortex anymore.

There is a growing literature focusing on the emerging idea that behavioral flexibility, rather than particular emotion regulation strategies per se, provides greater promise in predicting and influencing anxiety-related psychopathology. Yet this line of research and theoretical analysis appear to be plagued by its own challenges. For example, middle-level constructs, such as behavioral flexibility, are difficult to define, difficult to measure, and difficult to interpret in relation to clinical interventions. A key point that some researchers have made is that previous studies examining flexible use of emotion regulation strategies (or, more broadly, coping) have failed due to a lack of focus on context. That is, examining strategies in isolation of the context in which they are used provides limited information on the suitability, rigid adherence, or effectiveness of a given strategy in that situation. Several of these researchers have proposed the development of new models to define and measure various types of behavioral flexibility. We would like to suggest that an explanation of the phenomenon already exists and that we can go back to our behavioral roots to understand this phenomenon rather than focusing on defining and capturing a new process. Indeed, thorough contextual behavioral analyses already yield a useful account of what has been observed. We will articulate a model explaining behavioral flexibility using a functional, contextual framework, with anxiety-related disorders as an example.

We assessed building-related risk factors for lower respiratory symptoms in office workers. The National Institute for Occupational Safety and Health in 1993 collected data during indoor environmental health investigations of workplaces. We used multivariate logistic regression analyses to assess relationships between lower respiratory symptoms in office workers and risk factors plausibly related to microbiologic contamination. Among 2,435 occupants in 80 office buildings, frequent, work-related multiple lower respiratory symptoms were strongly associated, in multivariate models, with two risk factors for microbiologic contamination: poor pan drainage under cooling coils and debris in outside air intake. Associations tended to be stronger among those with a history of physician-diagnosed asthma. These findings suggest that adverse lower respiratory health effects from indoor work environments, although unusual, may occur in relation to poorly designed or maintained ventilation systems, particularly among previously diagnosed asthmatics. These findings require confirmation in more representative buildings

It is important for the elderly to maintain their skeletal muscle mass, which in turn helps to maintain physical functions. This study aimed to clarify factors related to skeletal muscle mass maintenance. Home-bound elderly (94 men and 216 women), at least 75 years of age, attending a day-care center in Tokyo, were enrolled in this study. Dentists specializing in dysphagia rehabilitation evaluated skeletal muscle mass, occlusal status and swallowing function. Physical function, cognitive function and nutritional status were also evaluated by interviewing caregivers. Correlations of skeletal muscle mass with various factors were determined in each gender group. Multiple regression analysis revealed that skeletal muscle mass was significantly related to nutritional status in both men and women. In men, there was a significant difference in skeletal muscle mass between those with and without occlusion of the natural teeth. Our results suggest that dental treatments and dentures would be useful for maintaining skeletal muscle mass, especially in men.

Full Text Available This study aimed to seek the evidence available in the literature regarding the factors related to adherence to treatment for systemic hypertension. It used the method of integrative review in the databases MEDLINE, CINAHL, and LILACS, using the keywords: hypertension, compliance, non-compliance, adherence, non-adherence, patient compliance, in the period 2004 – 2008, and articles in Portuguese, English and Spanish, with the use of a validated instrument and content analysis. 28 studies were selected, 64.3% of which had level of evidence VI. The following were identified as factors related to adherence to treatment: treatment costs, educational activities, sex, physician-patient relationship, physiological and behavioral aspects, drug therapy, attending checkups and lifestyle. The use of combined strategies is suggested in order to increase the individuals’ adherence to the treatment. Gaps point to the valorization of dialogic relationships for integrated and more efficacious health practices.

Societal stigmatization of HIV/AIDS due to assumptions about transmission and associated behaviors plays a substantial role in the psychosocial well-being of people living with this chronic illness, particularly for women in traditionally conservative geographic regions. Known for social conservatism, the Southern United States (US) holds the highest incidence rate of HIV infection in the US. A systematic search of four databases was used to identify 27 relevant scientific articles pertaining to HIV-related stigma among women living with HIV/AIDS in the Southern US. These studies revealed a rudimentary understanding of stigma sources, effects, and stigma-reduction interventions in this population. Due to the cultural specificity of stigma, further differentiation of stigma in discrete sectors of the South as well as a dialogue about the moral implications of stigma is necessary to lay the groundwork for patient-centered interventions to mitigate the destructive effects of stigma experienced by women in this region.
Epidermal growth factor (EGF) is a well-characterized polypeptide hormone with diverse biological activities, including stimulation of astrocyte division. A soluble astrocyte mitogen inhibitor, immunologically related to the EGF receptor, is present in rat brain. Injury to the brain causes a time-dependent reduction in the levels of this inhibitor and the concomitant appearance of EGF receptor on the astrocyte surface. Intracerebral injection of antibody capable of binding the inhibitor caused the appearance of numerous reactive astrocytes. EGF receptor-related inhibitors may play a key role in the control of glial cell division in both normal and injured brain.
This study explicates the influence of audience factors on website credibility and the subsequent effect that credibility has on the intention to revisit a site. It does so in an experimental setting in which participants were given two health-related search tasks. Reliance on the web for health-related information positively influenced website credibility in both searches. Knowledge was a significant predictor for the search task that required more cognitive ability. Of the credibility dimensions, trust/expertise and depth were significant predictors of intention to revisit a site in both searches. Fairness and goodwill were nonsignificant predictors in both searches.

The objective was to identify the main diagnoses, related factors and risk factors regarding the cardiovascular/pulmonary responses class proposed by NANDA version 2009-2011. This case series descriptive study was performed with twenty patients who underwent bariatric surgery in a public hospital in Fortaleza-CE, Brazil. Data were collected by two intensive care unit nurse specialists through interviews, physical examinations and the reviewing of medical records, and analyzed through descriptive statistics and cross-mapping. The nursing diagnoses identified with a frequency greater than 50% were: decreased cardiac output (75%), ineffective breathing patterns (65%), dysfunctional ventilatory weaning response (55%) and ineffective peripheral tissue perfusion (75%); in addition, fourteen related factors and five risk factors were identified. We verified the need for further studies to better define the diagnostic profile of these patients in order to direct nursing care towards the early detection of complications.

The aim of this study was to investigate and compare symptom experiences, beliefs, attitudes, and understanding of menopause and menopausal therapies in Australian and Laotian women. This was a cross-cultural, questionnaire-based study involving 108 women (56 Australian women and 52 Laotian women aged 40-65 y) attending outpatient clinics in Australia and Laos. Descriptive statistics and univariate analysis were conducted using Student's t test or Mann-Whitney U test, where appropriate. Psychological symptoms, depression, vasomotor symptoms, and sexual dysfunction were significantly higher in Australian women compared with Laotian women (P menopause as aging (57%), whereas most Laotian women reported not knowing what menopause meant to them (81%). Australian women's fears about menopause included weight gain (43%), aging (41%), and breast cancer (38%), whereas Laotian women reported not knowing about potential menopausal problems (85%). Exercise (55%), education and awareness (46%), and improving lifestyle (41%) were reported by Australian women as being effective in alleviating menopausal symptoms, with only 21% reporting not knowing what was effective compared with 83% of Laotian women. Many women reported not knowing the risks/benefits of hormonal therapies (50% of Australian women and 87% of Laotian women) and herbal therapies (79% of Australian women and 92% of Laotian women). General practitioners were the most common source of menopause information for both Australians (73%) and Laotians (67%). Sociocultural factors influence women's perception of menopause. Psychological symptoms, sexual dysfunction, and vasomotor symptoms are more commonly reported by Australian women than by Laotian women. Women have a limited understanding of the risks/benefits of menopausal therapies, and culturally appropriate education is needed.

Forty rail safety investigation reports were reviewed and a theoretical framework (the Human Factors Analysis and Classification System; HFACS) adopted as a means of identifying errors associated with rail accidents/incidents in Australia. Overall, HFACS proved useful in categorising errors from existing investigation reports and in capturing the full range of relevant rail human factors data. It was revealed that nearly half the incidents resulted from an equipment failure, most of these the product of inadequate maintenance or monitoring programs. In the remaining cases, slips of attention (i.e. skilled-based errors), associated with decreased alertness and physical fatigue, were the most common unsafe acts leading to accidents and incidents. Inadequate equipment design (e.g. driver safety systems) was frequently identified as an organisational influence and possibly contributed to the relatively large number of incidents/accidents resulting from attention failures. Nearly all incidents were associated with at least one organisational influence, suggesting that improvements to resource management, organisational climate and organisational processes are critical for Australian accident and incident reduction. Future work will aim to modify HFACS to generate a rail-specific framework for future error identification, accident analysis and accident investigation.

Burnout has been identified as an occupational hazard in the helping professions for many years and is often overlooked, as health-care systems strive to improve cost and quality. The Maslach Burnout Inventory (MBI) and the Areas of Worklife Survey (AWS) are tools for assessing burnout prevalence and its associated factors. We describe how we used them in outpatient clinics to assess burnout for multiple job types. Traditional statistical techniques and seemingly unrelated regression were used to describe the sample and evaluate the association between work life domains and burnout. Of 838 eligible participants, 467 (55.7%) were included for analysis. Burnout prevalence varied across three job categories: providers (37.5%), clinical assistants (24.6%), and other staff (28.0%). It was not related to age, gender, or years of tenure but was lower in part-time workers (24.6%) than in full-time workers (33.9%). Analysis of the AWS subscales identified organizational correlates of burnout.

The aim of the study is to identify medication errors related to computerized physician order entry in our hospital. At the end of this 1-year study (2008 to 2009), 378 beds were computerized by a business software. Medication errors were identified from notifications sent to the publisher of the software, feedback of health professionals and the analysis of Pharmacists' interventions formulate following prescription errors due to computerization. They were qualified according to the medication error's French dictionary of the French Society of Clinical Pharmacy. Thirty-five categories of medication errors were found. Most of them appear during prescription. Dosage and concentration errors, dose errors, omission errors and drug errors are the most frequent. Three main causes were found: human factor, closely related to the software settings and the quality of user training; communication problems, related to the ergonomics; conception problems, related to intuitiveness and intricacy of the software. These results confirm the existence of medication errors induced by computerized physician order entry systems. They highlight the need to involve initial and ongoing training of users, relevance and scalability of the setup and use of mature and certified software to minimized them.

The greatest weight gain for US. women occurs during the childbearing years of 25 to 34, and many obese women attribute their adult weight gain to childbearing. Few studies have examined psychosocial influences on women's behaviors during pregnancy, in part because of the lack of valid and reliable measures of psychosocial constructs relevant to pregnant women. Based on existing theory and an in-depth interview study, the psychosocial constructs of locus of control, self-efficacy, body image, feelings about motherhood, and career orientation were identified. Scales for each construct were constructed by drawing items from existing validated scales and writing items based on the in-depth interviews; their content validity assessed using factor analysis with oblique rotation and their reliability using Cronbach's alpha. Construct validity was assessed by examining the associations between scale scores and preexisting conditions of participants. Data for evaluating the scales came from a study of 622 pregnant women in a rural health care system who completed questionnaires and whose medical records were audited. Cronbach's alpha of the scales ranged from 0.73 to 0.89. Scale scores were strongly associated with lifestyle behaviors, body weight, and demographic characteristics of the participants. The analysis provides evidence of the validity of measures of psychosocial factors related to health behaviors of pregnant women. These measures should be useful in studying weight-related behaviors in pregnant women.

Literature on laterality emphasises the importance of implementing a comprehensive investigation of humans' and non-humans' laterality for both non-communication and communication functions. Adopting a global approach should enhance our understanding of the mechanistic drivers of human brain functional lateralisation and help to explore further the nature of the left-hemispheric systems for both functions. This study investigated human laterality for both functions by taking, for the first time, numerous behaviours and multiple potential influential factors into consideration. We analysed replies to the Rennes Laterality Questionnaire that takes into account simultaneously: participants' behavioural, demographic and social characteristics as well as their genetic/social learning components and collateral factors such as health problems. We collected and analysed a large data set including 450,220 item responses (317,594 items related to behavioural laterality and 132,626 items related to personal information) by 5904 participants. The majority of participants were right-lateralised for nine behavioural categories. The laterality of right-lateralised individuals for the behaviours considered varied very little between behavioural categories, contrary to the laterality of ambiguously- and left-lateralised individuals. This is the first evidence of the stability of right-lateralised individuals and the relative flexibility of ambiguously- and left-lateralised individuals with regards to behavioural laterality related to 60 everyday activities. Moreover, the laterality patterns of our study population were linked in particular to the following individual-related factors: demographic characteristics (current continent of residence), social characteristics (socio-professional group and study level), and collateral factors (writing hand, forced right-hand use, guiding eye, and health problems related to ear and back). We discuss our findings in relation to the

To describe a novel approach to hospital mortality meetings to elucidate understanding of contributory factors to child death and inform practice in the National Health Service. All child deaths were separately reviewed at a meeting attended by professionals across the healthcare pathway, and an assessment was made of contributory factors to death across domains intrinsic to the child, family and environment, parenting capacity and service delivery. Data were analysed from a centrally held database of records. All child deaths in a tertiary children's hospital between 1 April 2010 and 1 April 2013. Descriptive data summarising contributory factors to child deaths. 95 deaths were reviewed. In 85% cases, factors intrinsic to the child provided complete explanation for death. In 11% cases, factors in the family and environment and, in 5% cases, factors in parenting capacity, contributed to patient vulnerability. In 33% cases, factors in service provision contributed to patient vulnerability and in two patients provided complete explanation for death. 26% deaths were classified as potentially preventable and in those cases factors in service provision were more commonly identified than factors across other domains (OR: 4.89; 95% CI 1.26 to 18.9). Hospital child death review meetings attended by professionals involved in patient management across the healthcare pathway inform understanding of events leading to a child's death. Using a bioecological approach to scrutinise contributory factors the multidisciplinary team concluded most deaths occurred as a consequence of underlying illness. Although factors relating to service provision were commonly identified, they rarely provided a complete explanation for death. Efforts to reduce child mortality should be driven by an understanding of modifiable risk factors. Systematic data collection arising from a standardised approach to hospital reviews should be the basis for national mortality review processes and database

by using the following criteria: 1) a longitudinal study, 2) exposure to work-related psychosocial factors, 3) the outcome a measure of depression, 4) relevant statistical estimates, and 5) nonduplicated publication. Of the 14 studies, seven used standardized diagnostic instruments as measures...... of depression, whereas the other seven studies used self-administered questionnaires. The authors found moderate evidence for a relation between the psychological demands of the job and the development of depression, with relative risks of approximately 2.0. However, indication of publication bias weakens...... the evidence. Social support at work was associated with a decrease in risk for future depression, as all four studies dealing with this exposure showed associations with relative risks of about 0.6. Even if this literature study has identified work-related psychosocial factors that in high...

To understand the impact of ankylosing spondylitis (AS) on presenteeism and to explore its relationship to sick leave. AS patients completed a questionnaire consisting of sociodemographics, disease characteristics, and work outcomes, including sick leave and presenteeism, assessed by the Work Limitations Questionnaire (WLQ). Associations between a broad range of explanatory variables with the WLQ and AS-related sick leave were assessed by zero-inflated negative binomial and zero-inflated Poisson regressions. Of 311 employed patients (204 men [65.6%]), 18% had sick leave in the past month. Limitations in meeting time management demands (33.7%), physical demands (30.2%), mental-interpersonal demands (20.2%), and output (19.0%) were noted. With the mean ± SD WLQ index score of 6.7 ± 5.9, the average decrease in work productivity attributable to health was 6.3%; an extra 7.1% of work hours would be needed to compensate for lost productivity. Helplessness, female sex, and impaired health-related quality of life (Ankylosing Spondylitis Quality of Life instrument [ASQoL]) were major contributors to the level of presenteeism (P < 0.01). At-work limitations (WLQ) and lower quality of life (ASQoL) were significantly associated with probability of sick leave, while the length of sick leave was strongly associated with lower educational level and helplessness (P < 0.01), and in some models, also with disease duration and country of residence (P < 0.05). AS hinders patients' work, mainly in time management and physical demand domains. The WLQ and ASQoL are able to identify patients who incur sick leave. Helplessness contributes independently to the level of presenteeism and the length of sick leave. Copyright © 2014 by the American College of Rheumatology.

Full Text Available Added sugars are a controversial and hotly debated topic. Consumption of added sugars has been implicated in increased risk of a variety of chronic diseases including obesity, cardiovascular disease, diabetes and non-alcoholic fatty liver disease (NAFLD as well as cognitive decline and even some cancers. Support for these putative associations has been challenged, however, on a variety of fronts. The purpose of the current review is to summarize high impact evidence including systematic reviews, meta-analyses, and randomized controlled trials (RCTs, in an attempt to provide an overview of current evidence related to added sugars and health considerations. This paper is an extension of a symposium held at the Experimental Biology 2015 conference entitled “Sweeteners and Health: Current Understandings, Controversies, Recent Research Findings and Directions for Future Research”. We conclude based on high quality evidence from randomized controlled trials (RCT, systematic reviews and meta-analyses of cohort studies that singling out added sugars as unique culprits for metabolically based diseases such as obesity, diabetes and cardiovascular disease appears inconsistent with modern, high quality evidence and is very unlikely to yield health benefits. While it is prudent to consume added sugars in moderation, the reduction of these components of the diet without other reductions of caloric sources seems unlikely to achieve any meaningful benefit.

The Bolivian indigenous Ayoreo ethnic people are vulnerable to sexually transmitted infections and HIV. Ayoreo women who also work in sex trades belong to an extremely high-risk group, and prevention programs are not delivering effective outcomes for them. The aim of our study was to explore, describe, and understand behavioral and cultural patterns related to sexual and reproductive health in Ayoreo sex workers. A qualitative-ethnographic study was designed; data were collected through participant observation and in-depth interviews with sex workers and key informants. Two fundamental themes contributing to HIV risk for female Ayoreo sex workers in Bolivia emerged: reproductive/sexual freedom and sociocultural risk determinants. We concluded that the in-depth examination of the sexual-reproductive culture amongst the Ayoreo has provided useful information, which might contribute to the cultural adaptation and design of future policies and prevention programs for sexually transmitted infections and HIV in this group.

Objective: This study was conducted to find the epidemiological characteristics of bicycling-related maxillofacial fractures in a defined population, and identify factors contributing to injury. Methodology: A prospective study was carried out involving patients presenting with maxillofacial fractures sustained in bicycling-related accidents. Results: Between 908 of all cycling accidents attending for medical treatment, 122 patients (13% of all cycling accidents) were admitted with facial fractures between 2007 and 2014. Male and female ratio was 2.6:1, and the mean age was 29.4 years (standard deviation: 12.8, range: 12-79 years). Causes of injury included collisions (63%) and accidental falls (37%). The fracture patterns seen were mandibular (49%), zygomatic (32%), orbital (13%), nasal (7%), maxillary (2%), and frontal (2%). Condylar fractures were the most common of the mandibular fractures (63%). The most frequently observed concomitant lesions were orthopedic injuries. Conclusions: Bicycling-related maxillofacial injuries are common and therefore important to identify in order to design a sustainable transport system and for units that provide assistance to traffic accident victims. Missed diagnosis or delayed treatment can lead to facial deformities and functional problems. Wearing protective helmets and the improvement of the helmets design is one aspect that would be of interest for the prevention of injuries. Keywords: Cycling; bicycle-related trauma; maxillofacial fractures; risk factors; helmets. (Author)

This study was to investigate the associations between personal factors, health-related factors, history of fractures, and lifestyles and osteoporosis in the postmenopausal women. This study was based on a retrospective case-control study design conducted in the Phayao Hospital, Phayao Province, Thailand. The 136 menopausal women aged 40 years and older were examined for bone density with dual x-ray absorptiometry. Those who had test results less than or equal to -2.5 standard deviation when compared to the maximum mean bone mineral density of young women (T score ≤ -2.5) were classified as the case group, and those who had test results more than -2.5 standard deviation when compared to the maximum mean bone mineral density of young women (T score > -2.5) were classified as the control group. Data were collected using questionnaires. Binary logistic regression with forward stepwise (likelihood ratio) model selection was used to explore the associated factors. The factors statistically related to osteoporosis were body mass index (BMI; adjusted odds ratio (OR) = 0.81; 95 % confidence interval (CI), 0.71-0.93), age at menopause (OR = 0.88; 95 % CI, 0.79-0.99), history of fractures (OR = 10.00; 95 % CI, 2.71-36.94), family history of osteoporosis (OR = 2.66; 95 % CI, 1.04-6.77), and non-consumption of foods containing legumes, dried beans, and grains (OR = 13.84; 95 % CI, 2.08-92.11). It is recommended that more studies should be conducted on finding the optimal BMI and on the consumption of legumes, dried beans, and grains as osteoporotic protective factors.

Recent health care policies have supported the adoption of Information and Communication Technologies (ICT) but examples of failed ICT projects in this sector have highlighted the need for a greater understanding of the processes used to implement such innovations in complex organizations. This study examined the interaction of sociological and technological factors in the implementation of an Electronic Medical Record (EMR) system by a major national hospital. It aimed to obtain insights for managers planning such projects in the future and to examine the usefulness of Actor Network Theory (ANT) as a research tool in this context. Case study using documentary analysis, interviews and observations. Qualitative thematic analysis drawing on ANT. Qualitative analyses revealed a complex network of interactions between organizational stakeholders and technology that helped to shape the system and influence its acceptance and adoption. The EMR clearly emerged as a central 'actor' within this network. The results illustrate how important it is to plan innovative and complex information systems with reference to (i) the expressed needs and involvement of different actors, starting from the initial introductory phase; (ii) promoting commitment to the system and adopting a participative approach; (iii) defining and resourcing new roles within the organization capable of supporting and sustaining the change and (iv) assessing system impacts in order to mobilize the network around a common goal. The paper highlights the organizational, cultural, technological, and financial considerations that should be taken into account when planning strategies for the implementation of EMR systems in hospital settings. It also demonstrates how ANT may be usefully deployed in evaluating such projects.

Harm from gambling is known to impact individuals, families, and communities; and these harms are not restricted to people with a gambling disorder. Currently, there is no robust and inclusive internationally agreed upon definition of gambling harm. In addition, the current landscape of gambling policy and research uses inadequate proxy measures of harm, such as problem gambling symptomology, that contribute to a limited understanding of gambling harms. These issues impede efforts to address gambling from a public health perspective. Data regarding harms from gambling was gathered using four separate methodologies, a literature review, focus groups and interviews with professionals involved in the support and treatment of gambling problems, interviews with people who gamble and their affected others, and an analysis of public forum posts for people experiencing problems with gambling and their affected others. The experience of harm related to gambling was examined to generate a conceptual framework. The catalogue of harms experienced were organised as a taxonomy. The current paper proposes a definition and conceptual framework of gambling related harm that captures the full breadth of harms that gambling can contribute to; as well as a taxonomy of harms to facilitate the development of more appropriate measures of harm. Our aim is to create a dialogue that will lead to a more coherent interpretation of gambling harm across treatment providers, policy makers and researchers.

Objective: To investigate the understanding of infectious diseases, their prevention, and control, and the factors influencing this literacy among urban and rural residents of Zhejiang Province. Methods: In November- December 2014, a multistage stratified cluster sampling questionnaire was administered at study sites in eight districts of Zhejiang province: Hangzhou city Gongshu district, Hangzhou city Chun'an county, Wenzhou city Cangnan county, Dongyang city, Jiaxing city Jiashan county, Zhoushan city Putuo district, Linhai city, Lishui city Jinyun county. The inclusion criteria were: 15-60 years old, living locally for more than six continuous months, and no mental illness. The exclusion criteria were: foreigner residing locally, resident of Hong Kong, Macau, or Taiwan, or unable to communicate through speech or writing. In this study, 4 091 questionnaires were distributed, and 4 020 valid questionnaires were returned(98.26%). Health literacy regarding infectious diseases was measured at five levels: knowledge, skills, behaviors, access to information, and understanding of the prevention of infectious diseases. A total score was calculated for each questionnaire, and a total score of ≥80 was deemed to indicate an understanding of the prevention of infectious diseases. A χ 2 test was used to compare the levels of health literacy in different populations with single-factor analyses, and a multivariate unconditional logistic regression model was used to analyze the factors affecting infectious diseases prevention and treatment literacy levels. Results: Of the 4 020 respondents(aged(43.84 ± 10.28)years), 1 964 were male(48.86%)and 2 056 were female(51.14%). In the total surveyed population, 15.17%( n =610)understood the prevention of infectious diseases, 294 were male(14.97%)and 316 were female(15.37%)(χ 2 =2.48, P =0.115). When the participants in the different age groups were analyzed, 23.11%, 20.29%, 13.27%, and 11.04% of those aged 18- 29( n =116), 30- 39

To examine how 5-factor personality traits (extraversion, agreeableness, conscientiousness, neuroticism, and openness) and 3 higher-order health-related personality constructs (negative experience, optimistic control, and passivity) are related to self-reports of subjective health outcomes (positive and negative mood, physical symptoms, and general health concern) and objective health conditions (chronic illnesses, serious illnesses, and physical injuries). The study was carried out on a sample of 822 healthy volunteers (438 women and 384 men, from 18 to 84 years). Data were analyzed by hierarchical regression analyses for measures of subjective health outcomes used as criterion variables and binary logistic regression analyses for objective health conditions used as criterion variables. Three health-related personality constructs significantly predicted all subjective health measures above and beyond 5-factor personality dimensions. Out of the 5-factor personality dimensions, neuroticism was most consistently related to worse subjective health outcomes, while out of 3 health-related personality constructs, negative experience was related to worse and optimistic control to better subjective health outcomes. When objective health conditions were taken into account as criterion variables, both sets of variables were relatively weak predictors. Only 5-factor personality traits as a group of variables significantly predicted chronic illnesses (chi(2)(5)=15.06; P=0.012; Nagelkerke R(2)=0.032). Only neuroticism significantly predicted the presence of chronic illnesses (odds ratio [OR], 1.091; 95.0% confidence interval [CI], 1.040-1.144), whereas only optimistic control was related to more frequent physical injuries caused by accidents (OR, 1.285; 95.0% CI, 1.002-1.648). Five-factor personality traits and 3 health-related personality constructs may be useful factors in a multidisciplinary approach to understanding personality-health relationship.

The objective of this study is to describe, by quantitative and qualitative methods, industrial accidents occurred during three years in a metallurgic plant in the rural area to understand the possible causes. It is a case study in a metallurgic plant where 336 accidents were studied in a 3-year period by means of three procedures: analysis of accidents' registers, interviews with 166 hurt workers, and the organization of Focal Groups (111 workers) for discussion. The ratio of yearly incidence of accidents was 16.9%; 75 cases required more than 15 out-of-work days; 51.2% occurred in the morning and affected boilermakers (48.2%). Among the interviewed workers, average schooling was 8.8 years, age ranged from 31-50 years (55.4%), 64.5% of workers had already suffered more than one accident. Besides, workers exposed to intense noise (+ 90 dBA) were the most affected (53%). In the focal groups, perceptions and feelings of workers regarding the accidents were identified that had not appeared in the previous stages. It can be concluded that focal groups allow for a better identification of factors that may contribute for accidents such as performance pressures, extra-hours of work, low wages, and precarious conditions of work and work organization.

Obesity prevention efforts in Aboriginal (First Nations, Métis, or Inuit) communities in Canada should focus predominantly on children given their demographic significance and the accelerated time course of occurrence of type 2 diabetes mellitus in the Aboriginal population. A socioecological model to address childhood obesity in Aboriginal populations would focus on the numerous environments at different times in childhood that influence weight status, including prenatal, sociocultural, family, and community environments. Importantly, for Aboriginal children, obesity interventions need to also be situated within the context of a history of colonization and inequities in the social determinants of health. This review therefore advocates for the inclusion of a historical perspective and a life-course approach to obesity prevention in Aboriginal children in addition to developing interventions around the socioecological framework. We emphasize that childhood obesity prevention efforts should focus on promoting maternal health behaviours before and during pregnancy, and on breastfeeding and good infant and child nutrition in the postpartum and early childhood development periods. Ameliorating food insecurity by focusing on improving the sociodemographic risk factors for it, such as increasing income and educational attainment, are essential. More research is required to understand and measure obesogenic Aboriginal environments, to examine how altering specific environments modifies the foods that children eat and the activities that they do, and to examine how restoring and rebuilding cultural continuity in Aboriginal communities modifies the many determinants of obesity. This research needs to be done with the full participation of Aboriginal communities as partners in the research.

Lifestyle and health-related factors are critical components of the risk for cognitive aging among veterans. Because dementia has a prolonged prodromal phase, understanding effects across the life course could help focus the timing and duration of prevention targets. This perspective may be especially relevant for veterans and health behaviors. Military service may promote development and maintenance of healthy lifestyle behaviors, but the period directly after active duty has ended could be an important transition stage and opportunity to address some important risk factors. Targeting multiple pathways in one intervention may maximize efficiency and benefits for veterans. A recent review of modifiable risk factors for Alzheimer's disease estimated that a 25% reduction of a combination of seven modifiable risk factors including diabetes, hypertension, obesity, depression, physical inactivity, smoking, and education/cognitive inactivity could prevent up to 3 million cases worldwide and 492,000 cases in the United States. Lifestyle interventions to address cardiovascular health in veterans may serve as useful models with both physical and cognitive activity components, dietary intervention, and vascular risk factor management. Although the evidence is accumulating for lifestyle and health-related risk factors as well as military risk factors, more studies are needed to characterize these factors in veterans and to examine the potential interactions between them.

Full Text Available The Specialized Dental Care Centers (SDCC have the mission to expand access to public medium complexity dental care and support the primary health care actions at this level of complexity. However, it is necessary to ensure the quality of services and to evaluate such services continuously to identify weaknesses and strengths that support the processes of leadership/management. Nevertheless, there is a dearth of studies on the assessment of oral health in specialized care that may indicate which factors should be investigated. Therefore, this integrated literature review sought to explore the plethora of publications on the evaluation of SDCC in the LILACS and MEDLINE data bases in October 2013 to identify factors possibly related to the performance of such health services. Thus, 13 references were included in this review pointing to forms of organization and management of work processes related to the creation of healthcare networks (operation of regulation centers and setting up of health consortiums. They include the contextual characteristics of the places where SDCCs are located (population size, Family Health Strategy coverage, Municipal Human Development Index, governance, governing capacity were factors that influenced the SDCCs performance.

Incidence and mortality rates for cancer have increased dramatically in the recent 30 years in Taiwan. However, not all patients receive treatment. Treatment refusal might impair patient survival and life quality. In order to improve this situation, we proposed this study to evaluate factors that are related to refusal of treatment in cancer patients via a cancer case manager system. This study analysed data from a case management system during the period from 2010 to 2012 at a medical center in Northern Taiwan. We enrolled a total of 14,974 patients who were diagnosed with cancer. Using the PRECEDE Model as a framework, we conducted logistic regression analysis to identify independent variables that are significantly associated with refusal of therapy in cancer patients. A multivariate logistic regression model was also applied to estimate adjusted the odds ratios (ORs) with 95% confidence intervals (95%CI). A total of 253 patients (1.69%) refused treatment. The multivariate logistic regression result showed that the high risk factors for refusal of treatment in cancer patient included: concerns about adverse effects (prefuse treatment have poor survival. The present study provides evidence of factors that are related to refusal of therapy and might be helpful for further application and improvement of cancer care.

The role of family relationships in the lives of older adults has received substantial attention in recent decades. Scholars have increasingly looked beyond simple models of family relations to approaches that recognize the complex and sometimes contradictory nature of these ties. One of the most exciting conceptual and methodological developments is the application of within-family differences approaches. In this paper, we focus on the ways in which such within-family approaches can extend the understanding of patterns and consequences of intergenerational ties in adulthood. Following a review of the conceptual underpinnings of within-family differences approaches, we provide empirical illustrations of these approaches from three projects conducted in the United States: the Family Exchanges Study (FES), the Longitudinal Study of Generations (LSOG), and the Within-Family Differences Study (WFDS). Analyses from the FES, LSOG, and WFDS reveal differences in the consequences of patterns of intergenerational relations found when using within-family compared to between-family approaches. In particular, these analyses demonstrate considerable variation within families that shapes patterns and consequences of parent-adult child ties that is masked when such variations are not taken into account. Within-family differences approaches have been shown to shed new light on intergenerational relations. Despite the value of within-family designs, their use may be limited by the higher investment of finances and time required to implement such studies. © The Author 2017.

To present the results of examinations of the risk factors for age-related macular degeneration (AMD) carried out in the last 3 years. Our clinical material comprised 119 patients, 69 women and 50 men, aged 43-85, mean age 70 years. Using classification according to the worse eye, there were 20 patients with drusen, 27 with atrophic changes and 72 with exudative form and AMD. The following risk factors were evaluated: age, sex, body mass index, history of general medical conditions, cigarette smoking, sun exposure, family history of AMD and ocular conditions such as iris color, lens opacities, hyperopia, gerontoxon and changes in retinal vessels. The significant relationships were found between the development of AMD and the age of patients, as well as between the advanced forms of AMD and the history of cardiovascular diseases and sclerotic changes in retinal vessels, 87% of examined patients have light iris and 52% body mass index above 26. The studies confirmed the role of age in the development of AMD and indicated cardiovascular disturbances, increased body mass index and light iris as the possible risk factors for AMD that are most worth further studying. The special attention should be also paid to drusen as the risk factor of AMD.

This study aimed to clarify the factors related to self-efficacy experienced by psychiatric nurses. Analysis of qualitative descriptive data from a free self-description questionnaire administered to 16 psychiatric nurses working in psychiatric hospitals revealed 24 codes across the following 8 categories as factors that increase self-efficacy: A1. possibility of practical use in nursing, A2. nursing judgment, A3. improvement of psychiatric symptoms, A4. the patients presenting a positive attitude, A5. building a relationship of trust with the patients, A6. building a relationship of trust with other nurses, A7. work progressing according to plan and A8. team medical practice. Twenty-five codes across the following 10 categories were identified as factors that decrease self-efficacy: B1. lack of communication, B2. uncertainty in caregiving, B3. recurrence of psychiatric symptoms, B4. feeling overpowered by a patient, B5. sense of being too busy to work adequately, B6. difficulty in bringing about self-improvement, B7. sense of loss regarding one's role as a nurse, B8. lack of physical strength, B9. mechanical performance of nursing and B10. fluctuating view of nursing due to mistakes. These factors require intervention for psychiatric nurses' self-efficacy.

With support from the U.S. President's Emergency Plan for AIDS Relief and the global fund for HIV, tuberculosis, and malaria, Nigeria offers free services for prevention of mother-to-child transmission of HIV. However, uptake of these services is low, and pediatric transmission of HIV remains a significant public health challenge. Using the PEN-3 cultural model as the theoretical framework, we examined social, cultural, and contextual factors that influenced uptake of HIV counseling and testing among pregnant women and their male partners. This was a qualitative study of participants in the Healthy Beginning Initiative (HBI), a congregation-based program to prevent mother-to-child transmission of HIV in Enugu, southeast Nigeria. We conducted eight focus group discussion sessions with 83 pregnant women and their male partners. Participants' perspectives on why they did or did not test for HIV were obtained. The most cited reasons for getting tested for HIV included the following: "the need to know one's status", "the role of prenatal testing" (positive perceptions); "the role of the church", "personal rapport with healthcare worker" (positive enablers); and the "influence of marriage" (positive nurturer). The most cited reason for not testing were: "fear of HIV test", "shame associated with HIV+ test results", "conspiratorial beliefs about HIV testing" (negative perceptions); "lack of confidentiality with HIV testing", (negative enabler); and "HIV-related stigma from family and community systems" (negative nurturer). Overall, numerous facilitators and barriers influence uptake of HIV testing in the study setting. Public health practitioners and policymakers need to consider how sociocultural and religious factors unique to specific local contexts may promote or hinder uptake of available HIV/AIDS prevention and care interventions.

We aimed to describe the sleep profiles and associated factors of poor sleep in adolescents. We gave a sleep questionnaire and Strengths and Difficulties Questionnaire to 3,441 high school adolescents (15-18 years) in Gaziantep, Turkey. Adolescents reported a requirement of 10.4 hours of sleep on average to feel their best during the day. However, total night sleep time (TNST) was 7.42 +/- 1.48 hours on school nights and 9.40 +/- 1.37 on non-school nights. TNST of > or =9 hours on both school nights and non-school nights was detected in 8.2%. Average bedtime and wake-up time were 23:16 and 06:41 on school nights. Bedtime was approximately 30 minutes later on non-school nights. The shift in wake-up time was nearly 2.5 hours. Statistical analysis by logistic regression model showed that TNST was most significantly correlated with school start time (morning versus afternoon) irrespective of school or non-school nights. TNST on school nights was negatively correlated with age, passive smoking at home, drinking tea/coffee, and conduct problem, whereas TNST on non-school nights was negatively correlated with the mother's education, male gender, body mass index, number of household members, and having a television in the bedroom. Daytime napping (21.3%) was associated with morning start time, age, female gender, and mother's education. Sleep-onset insomnia with sleep latency >30 minutes (21%) was not related to age or gender; however, it was associated with abnormal breathing during sleep. The findings revealed that inadequate sleep is quite prevalent among high school adolescents. Given the fact that most of the associated factors are modifiable, inadequate sleep is not inevitable for adolescents.

To understand the influential factors related to sexual behaviors among Asian-American adolescents and to evaluate common factors across successful sexual education programs for this population. Despite a rapid increase in cases of STIs/HIV among Asian-American populations, there remains a need for a comprehensive understanding of the influential factors related to risky sexual behaviors for this population. An integrative literature review was conducted. Peer-reviewed articles and government resources were analyzed. Five influential factors were identified: family-centered cultural values, parental relationship, acculturation, gender roles, and lack of knowledge and information about sex and STIs. Only two sexual educational programs met the inclusion criteria and provided evidence towards effectiveness: Safer Choices and Seattle Social Development Project. The findings of this study indicate an urgent need for culturally sensitive sexual education programs that incorporate the identified influential factors, especially cultural values in order to reduce risky sexual behaviors among Asian-American adolescents.

This study aimed to evaluate the risk factors for falls in hospitalized children in relation to their caregivers. This was a case control study to evaluate the risk factors for falls in hospitalized children in relation to their caregivers. The children included in our study were at the hospital between June 2014 and June 2015. Demographic data of patients, caregivers, some habits; education level; and number of siblings were recorded. The data of 117 patients were evaluated, and there were 39 patients with a fall event and 78 patients who did not experience a fall. The mean age for the fall group and the non-fall group were 14.71±9.36 and 15.62±10.65months, respectively. The mean age for the caregivers of the fall group and the non-fall group were 29.33±5.89 and 29.53±5.56years, respectively. There was a statistically significant difference in fall risk related to the caregivers' education level (pfalls, by multivariate logistic regression, showed that low educational level of caregivers (OR=0.361; CI=0.196-0.665; pfalls. The data obtained in our study have shown that caregivers play a key role in fall events in hospitalized children. Nurses and other health workers should consider children's caregivers educational level and habits for prevention of hospitalized children falls. Copyright © 2016 Elsevier Inc. All rights reserved.

There is general agreement that lumbosacral nerve root compression is a prime factor in the pathogenesis of sciatica and neurogenic claudication, although humoral and vascular factors certainly play a role as well. This book focuses on imaging of the various ways in which nerve root compression can come about, and assessing which anatomic features are reliably associated with the occurrence of radicular pain, as opposed to morphologic findings which are probably coincidental. After a discussion of the nature of radicular pain and related symptoms, spinal imaging techniques and options are reviewed, with emphasis on the role of MR myelography in assessing the condition of the intradural nerve roots. A chapter on normal topographic, sectional, and functional (dynamic) radiologic anatomy is followed by a presentation on pathologic anatomy, addressing the various mechanisms of nerve root compression. In the chapter on pre- and postoperative imaging, features which may help to predict the evolution of the symptoms are discussed, with an eye to selecting candidates for surgical treatment. This is followed by a discussion of the role and limitations of imaging studies in various adverse postoperative conditions. In illustrations involving patient studies, imaging features are linked where possible to the clinical symptoms and history of the individuals involved. (orig.)

The primary aim of this study was to understand factors associated with condom use behavior among club-working women and identify the most influential factors to be addressed in future health programs. A total of 158 club-working women were surveyed from 3 midsize cities in South Korea from July to September 2004. Survey questionnaires were developed based on the theory of planned behavior. A total of 7 distinct themes emerged: Health aspects, Customer related, Pleasure related, Finance related, Societal norm, Occupational norm, and Perceived control. The results indicated that the Customer-related theme, Societal norm, and Occupational norm were statistically significant factors affecting condom use. On the other hand, self-related factors such as health, pleasure, and finance are not significantly related to the condom use behavior of club-working women in South Korea, suggesting that the currently used knowledge-focused education programs may not be sufficient for this population.

Taiwan is a multicultural and multiethnic society with a growing number of immigrants who have diverse ethnic, racial, and cultural needs. Although this diversity highlights the pressing need for culturally competent healthcare providers, cultural competence is a concept that is little understood and implemented only sporadically in Taiwan. This study investigates the cultural competence of Taiwanese nurses and the related factors of influence. An online self-report survey was used to collect data from 221 Taiwanese nurses from December 2012 through January 2013. Data from the demographic questionnaire, the Nurses' Cultural Competence Scale, and the Perceived Nurses' Cultural Competence Rating were analyzed using descriptive statistics, Pearson correlation, independent sample t tests, and multiple regressions. The cultural competence of the participants was in the "low to moderate" range, with relatively higher mean scores for the subscales of cultural awareness and cultural sensitivity and relatively lower scores for the subscales of cultural knowledge and cultural skills. Participants generally perceived themselves as being "not culturally competent." Variables found to predict cultural competence included years of work experience, hours of continuing education related to cultural nursing care, and frequency of caring for clients from culturally and ethnically diverse backgrounds. Participating Taiwanese nurses rated their level of cultural competence as in the low-to-moderate range and self-perceived as being not culturally competent. These findings support the need to further expand and enhance cultural-competence-related continuing education and to address the topic of cultural care in the nursing curricula.

This study aimed to analyze factors affecting social and family relations of young mothers in the two-year postpartum period. This was a cross-sectional study of 464 young mothers in Teresina, Piauí State, Brazil, who gave birth during the first four months of 2006 in six maternity hospitals. Data were collected from May to December 2008 after identifying the young women in the maternity hospital records. Multivariate analysis used multinomial logistic regression. Married young women (including those in common-law marriages) were 80% less likely to have negative relations with their partners. Participants 20 to 22 years of age related 2.4 times better with their mothers than those 17 to 19 years of age. Young women not attending school showed 97% higher odds of negative changes in relations with friends, and Catholics were 50% less likely to have worse relations with friends following childbirth. Measures are needed to orient individuals living with young mothers (especially their partners and mothers) concerning the importance of support in this phase of life, particularly encouraging them to stay in school.

To study the distribution, prevalence, determinants, and association between substance use (e.g., cigarettes, alcohol, and illegal drugs) and eating attitudes and behavior of high school students in the Negev region of Israel in order to provide an improved basis for prevention and health services. An anonymous questionnaire regarding attitudes and behavior related to substance use and eating (e.g., breakfast before school, a snack or meal during school time, and three meals a day) was answered by 1,513 high school age youth. The study participants were at greater risk of poor eating behavior if they: (1) used cigarettes, alcohol, and/or illicit substances (p illicit substances were used or not used, more than 50% of the youth reported not eating breakfast and 30% indicated they did not eat three meals daily. There are many concerns about the use and abuse of both licit and illicit substances among adolescents. More attention, however, needs to be given to the relationship between substance use and the attitudes and behavior of young people toward their health, including proper eating habits. The results support the need to develop drug prevention and health programs that are more comprehensive in terms of addressing the broad range of factors associated with adolescent growth and development.

We examined the factors related to life space and changes in the care level after one year in daycare center users. The participants were 83 older adults (age, > 65 years; mean age, 79.5±6.8 years) with MMSE scores of ≥20, who could walk independently, who needed support (1-2) or care (1), and who underwent rehabilitation at a daycare center. The life space was evaluated by the Life Space Assessment (LSA). The subjects' basic information (i.e., age, medical history.) was collected, and their physical function (i.e., grip strength, timed up and go test [TUG]), mental function (i.e., vitality, fear of falls), and social function (i.e., friends, hobbies, public transportation) were assessed to investigate the factors associated with their LSA scores. In addition, a follow-up survey was conducted on the care level at approximately one year later. A multiple regression analysis indicated that TUG scores (β=-0.33), hobbies (β=0.30), friends (β=0.29), public transportation (β=0.26), and grip strength (β=0.24) were related to the life space. Next, the participants were divided into LSA-high and LSA-low groups, and changes in the care level (improvement, maintenance, deterioration) at approximately one year after the initial assessment were examined using a chi-squared test. A significant difference was observed in the distribution of the groups (p=0.03). Multiple factors were related to the life space. Moreover, it is possible that improvements in the level of care may be achieved by improving the life space.

To examine the effect of general contact lens and material characteristics, care solutions, treatment, and patient-related factors on contact lens-related dry eye. The data were derived from the Contact Lens and Dry Eye Study, designed as a cross-sectional and nested case-control study including 360 subjects. In separate statistical models, logistic regression was used to examine general contact lens characteristics, specific hydrogel lens materials, care solutions, and patient-related factors associated with dry eye status (controlled for age, gender, and current treatments). Several factors were significantly associated with dry eye, including treatment factors such as a recent contact lens refitting (odds ratios [OR] = 5.75, 95% confidence intervals [CI] = 2.14 to 15.46) and use of artificial tears/rewetting drops (OR = 1.09, 95% CI = 1.02 to 1.16), in addition, currently worn materials including Food and Drug Administration (FDA) group II (OR = 2.98, 95% CI = 1.14 to 6.19) and IV (OR = 1.87, 95% CI = 1.08 to 3.24). Significant patient-related factors included decreased overall satisfaction (OR = 3.57, 95% CI = 2.08 to 5.88,), dry eye in the absence of contact lens wear (OR = 6.54, 95% CI = 2.57 to 16.62), reduced daily lens wear duration (OR = 1.16, 95% CI = 1.06 to 1.26), and reduced ability to wear lenses as long as desired (OR = 2.44, 95% CI = 1.30 to 4.54). Care solutions were not associated with contact lens-related dry eye. The strong association of common treatment factors with dry eye status in contact lens wearers suggests that these treatments are not entirely effective. The use of high water content materials was strongly related to dry eye in lens wearers, whereas care solutions were not. Contact lens-related dry eye was also associated with several patient-related factors such as greater ocular discomfort (without lenses), dissatisfaction, and inability to wear lenses for desired durations.

In our previous research, we observed that stress, depression, social support, and self-esteem were closely related to each other. The primary purpose of the research presented here was to evaluate the “self‒esteem,” “depression,” “social-support,” and “stress” of Japanese and Chinese nursing students and make comparisons between them. The second purpose was to examine the relationships among these factors. Findings revealed that about 45.6 % of Japanese and about 67.5 % of Chinese students h...
Full Text Available Problems concerning quality and productivity in the construction sector have been a recurrent issue for many years and seem to remain in spite of various initiatives for resolving them. This situation is a result of human action. From social sciences we know that psychological factors crucially influence action design. Knowledge of this influence seems however to be underestimated in the construction sector, and could represent a missing link between strategies, plans and instructions, and the actions carried out.In order to prospect for new problem solving approaches we undertook a questionnaire-based survey to investigate how individuals in the sector perceive the importance and occurrence of, and attention directed to, different proposed causes of inadequate performance. The design of the questionnaire enabled comparisons of different answers to look beyond the respondents’ overt answers. The result suggests that (1 the whole problem solving situation, including individual, relational and contextual problem components should be addressed as ‘the problem’; (2 the workforce has the ambition and courage to do what is expected but does not always have adequate information and the ability or resources to do it; (3 mental information distortion might be responsible for affecting the way the world is understood.

The purposes of this study are to (1) examine the extent to which young adult Ecstasy users recently reported having had multiple sex partners and (2) identify the factors predictive of engaging in this behavior. Potential predictors included demographic characteristics, background and experiences measures, childhood maltreatment experiences, substance use variables, and measures assessing psychological/psychosocial functioning. This research is based on a sample of 283 young adult recurrent users of the drug, Ecstasy. Study participants were recruited in Atlanta, Georgia between August 2002 and August 2004 using a targeted sampling and ethnographic mapping approach. Interviews took approximately two hours to complete. Nearly one-third of the study participants had more than one sex partner during the preceding month, and sexual protection rates tended to be low. Multivariate logistic regression analysis revealed seven predictors associated with an increased likelihood of having multiple sex partners: (1) being nonwhite, (2) knowing someone who was HIV-positive, (3) younger age of first sexual experience, (4) using Ecstasy for its touch-enhancing qualities, (5) higher self-esteem, (6) handling disagreements more dysfunctionally, and (7) not being involved in a romantic relationship. The HIV prevention- and intervention-related implications of these findings are discussed.

Data from epidemiological studies of humans exposed to potentially harmful substances are usually analyzed using methods that account for the dependence of risks on time-related factors such as age and follow-up period. Recently developed statistical procedures allow modeling of the age-specific risks as a function of dose as well as factors such as age at exposure, time since exposure, exposure duration, and dose rate. These procedures potentially allow more rigorous inferences and clearer understanding of the patterns of risk observed in epidemiological studies than has been available in the past. Statistical procedures that consider time-related factors can also be applied to laboratory animal data, providing information that is useful for the problems involved in extrapolating from animal studies to humans. By applying such procedures to data on exposure to the same substance in different species (including humans) or to different substances in the same species, better understanding of the relationship of risks across species and across substances can be achieved. In addition, such statistical procedures allow appropriate treatment of exposure that is accumulated over time and lead to improved understanding of patterns of risk over time. The approach is illustrated using data from a lifespan study of beagle dogs exposed to inhaled Pu

Drug side effects represent a common reason for stopping drug development during clinical trials. Improving our ability to understand drug side effects is necessary to reduce attrition rates during drug development as well as the risk of discovering novel side effects in available drugs. Today, most investigations deal with isolated side effects and overlook possible redundancy and their frequent co-occurrence. In this work, drug annotations are collected from SIDER and DrugBank databases. Terms describing individual side effects reported in SIDER are clustered with a semantic similarity measure into term clusters (TCs). Maximal frequent itemsets are extracted from the resulting drug x TC binary table, leading to the identification of what we call side-effect profiles (SEPs). A SEP is defined as the longest combination of TCs which are shared by a significant number of drugs. Frequent SEPs are explored on the basis of integrated drug and target descriptors using two machine learning methods: decision-trees and inductive-logic programming. Although both methods yield explicit models, inductive-logic programming method performs relational learning and is able to exploit not only drug properties but also background knowledge. Learning efficiency is evaluated by cross-validation and direct testing with new molecules. Comparison of the two machine-learning methods shows that the inductive-logic-programming method displays a greater sensitivity than decision trees and successfully exploit background knowledge such as functional annotations and pathways of drug targets, thereby producing rich and expressive rules. All models and theories are available on a dedicated web site. Side effect profiles covering significant number of drugs have been extracted from a drug ×side-effect association table. Integration of background knowledge concerning both chemical and biological spaces has been combined with a relational learning method for discovering rules which explicitly

This study examined patterns, characteristics, and predictors of cross-racial friendships as the context for understanding contemporary race relations. A national survey included 1,055 respondents, of whom 55% were white, 32% were black, and 74% were female; ages ranged from 18 to ≥65 years. Focus groups were conducted to assess societal and personal benefits. Participants (n = 31) were racially diverse and aged 20 to 66 years. After accounting for multiple covariates, regression analysis revealed that Asians, Hispanics, and multiracial individuals are more likely than their white and black counterparts to have cross-racial friends. Females were less likely than males to have 8 or more cross-racial friends. Regression analysis revealed that the depth of cross-racial friendships was greater for women than men and for those who shared more life experiences. Increasing age was associated with lower cross-racial friendship depth. Qualitative analysis of open-ended questions and focus group data established the social context as directly relevant to the number and depth of friendships. Despite the level of depth in cross-racial friendships, respondents described a general reluctance to discuss any racially charged societal events, such as police shootings of unarmed black men. This study identified salient characteristics of individuals associated with cross-racial friendships and highlighted the influence of the social, historical, and political context in shaping such friendships. Our findings suggest that contemporary race relations reflect progress as well as polarization. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Full Text Available Abstract Background Despite increasing recognition of the importance of involving patients in decisions on preventive healthcare interventions, little is known about how well patients understand and utilise information provided on the relative benefits from these interventions. The aim of this study was to explore whether lay people can discriminate between preventive interventions when effectiveness is presented in terms of relative risk reduction (RRR, and whether such discrimination is influenced by presentation of baseline risk. Methods The study was a randomised cross-sectional interview survey of a representative sample (n = 1,519 of lay people with mean age 59 (range 40–98 years in Denmark. In addition to demographic information, respondents were asked to consider a hypothetical drug treatment to prevent heart attack. Its effectiveness was randomly presented as RRR of 10, 20, 30, 40, 50 or 60 percent, and half of the respondents were presented with quantitative information on the baseline risk of heart attack. The respondents had also been asked whether they were diagnosed with hypercholesterolemia or had experienced a heart attack. Results In total, 873 (58% of the respondents consented to the hypothetical treatment. While 49% accepted the treatment when RRR = 10%, the acceptance rate was 58–60% for RRR>10. There was no significant difference in acceptance rates across respondents irrespective of whether they had been presented with quantitative information on baseline risk or not. Conclusion In this study, lay people's decisions about therapy were only slightly influenced by the magnitude of the effect when it was presented in terms of RRR. The results may indicate that lay people have difficulties in discriminating between levels of effectiveness when they are presented in terms of RRR.

As part of the planning process for a larger survey study to examine factors affecting employers' intention to hire and hiring of people with disabilities, a series of three semi-structured focus groups were held with key hiring decision makers, such as Human Resources directors, Chief Operating Officers (COOs), or Chief Executive Officers (CEOs) of small, medium, and large Seattle area companies. The chief goals of the focus groups were to elicit and refine the participants' beliefs, normative influences, and perceived control relative to hiring workers with disabilities. Narrative data obtained from the focus group discussion were examined using the Theory of Planned Behavior (TPB) to identify themes expressed by the focus group participants within the context of company size. Themes did vary by company size, but a prevailing concern across all companies related to questions about the efficiency/effectiveness of contact with vocational rehabilitation agencies. For both small- and mid-sized companies, there was a belief that people with disabilities could not do the work or were somehow less qualified. For large companies, convincing departmental and team managers that outreaching workers with disabilities would be a worthwhile hiring practice remained a challenge. The themes derived from this study can be used to help occupational rehabilitation professionals develop educational and marketing interventions to improve employers' attitudes toward hiring and retaining individuals with disabilities.

Mind wandering has been identified as a possible cause for stress-related working memory (WM) task impairments following laboratory stressors. The current study attempted to induce mind wandering regarding negative, positive, or neutral events using an expressive writing task and examined the impact on WM task performance. We examined the role of mind wandering in understanding the impact of life stress on WM. Additionally, we explored the role of thought suppression on the relationship between mind wandering and WM. One hundred and fifty participants completed WM measures before (Time 1) and after (Time 2) the writing manipulation. The writing manipulation did not alter mind wandering or WM task performance. Time 1 WM predicted mind wandering during the Time 2 WM task, which subsequently predicted poorer Time 2 WM task performance. The impact of daily life stress on WM was mediated by mind wandering. Trait levels of thought suppression moderated the impact of mind wandering on WM. Specifically, higher levels of suppression resulted in stronger negative impact of mind wandering on WM task performance. Findings are discussed in terms of the impact of mind wandering on WM task performance.

To investigate the work-related musculoskeletal disorders among automobile assembly workers, to discusses the related risk factors and their relationship. The selected 1508 automobile assembly workers from a north car manufacturing company were regarded as the study object. The hazard zone jobs checklist, Nordic musculoskeletal symptom questionnaire (NMQ) and pain questionnaire were used to perform the epidemiological cross-sectional and retrospective survey and study for the General status, awkward ergonomics factors and related influencing factors, and musculoskeletal disorders of workers. The predominant body sites of occurring WMSDs among automobile assembly workers were mainly low back, wrist, neck and shoulders, the predominant workshop section of occurring WMSDs were mostly concentrated in engine compartment, interior ornament, door cover, chassis and debugging section. The predominant body site of WMSDs among engine compartment and chassis section workers was low back, interior ornament workers were low back and wrist, door cover workers was wrist, chassis workers was low back, debugging workers were neck and low back. Neck musculoskeletal disorders had the trend with the increase of a body height; Smoking may increase the occurrence of musculoskeletal disorders. The WMSDs appears to be a serious ergonomic proble assem among automobile assembly workers, predominant occurring site of WMSDs is with different workshop section, its characteristics is quite obvious, probably related to its existing awkward work position or activities. The worker height and smoking habits may be important factors which affect musculoskeletal disorders happen.

Work-related musculoskeletal disorders cause chronic pain and functional impairment, impose heavy costs on society, and reduce productivity. In this position paper from the Scientific Committee for Musculoskeletal Disorders of the ICOH, the most important risk factors at work are described. Work-related musculoskeletal disorders have high incidences and prevalences among workers who are exposed to manual handling, repetitive and static work, vibrations, and poor psychological and social conditions. The application of ergonomic principles in the workplace is the best method for prevention. International organizations should develop standards, common classifications, and terminologies. Surveillance systems should be further developed nationally and in workplaces, and more effort should be directed to information dissemination, education, and training.

We examine the nonlinear structure of gravitationally collapsed objects that form in our simulations of wavelike cold dark matter, described by the Schrödinger-Poisson (SP) equation with a particle mass ∼10(-22) eV. A distinct gravitationally self-bound solitonic core is found at the center of every halo, with a profile quite different from cores modeled in the warm or self-interacting dark matter scenarios. Furthermore, we show that each solitonic core is surrounded by an extended halo composed of large fluctuating dark matter granules which modulate the halo density on a scale comparable to the diameter of the solitonic core. The scaling symmetry of the SP equation and the uncertainty principle tightly relate the core mass to the halo specific energy, which, in the context of cosmological structure formation, leads to a simple scaling between core mass (Mc) and halo mass (Mh), Mc∝a(-1/2)Mh(1/3), where a is the cosmic scale factor. We verify this scaling relation by (i) examining the internal structure of a statistical sample of virialized halos that form in our 3D cosmological simulations and by (ii) merging multiple solitons to create individual virialized objects. Sufficient simulation resolution is achieved by adaptive mesh refinement and graphic processing units acceleration. From this scaling relation, present dwarf satellite galaxies are predicted to have kiloparsec-sized cores and a minimum mass of ∼10(8)M⊙, capable of solving the small-scale controversies in the cold dark matter model. Moreover, galaxies of 2×10(12)M⊙ at z=8 should have massive solitonic cores of ∼2×10(9)M⊙ within ∼60 pc. Such cores can provide a favorable local environment for funneling the gas that leads to the prompt formation of early stellar spheroids and quasars.

This research study investigated how undergraduate college biology students' level of understanding of the role of the seed plant root system relates to their level of understanding of photosynthesis. This research was conducted with 65 undergraduate non-majors biology who had completed 1 year of biology at Louisiana State University in Baton Rouge and Southeastern Louisiana University in Hammond. A root probe instrument was developed from some scientifically acceptable propositional statements about the root system, the process of photosynthesis, as well as the holistic nature of the tree. These were derived from research reviews of the science education and the arboriculture literature. This was administered to 65 students selected randomly from class lists of the two institutions. Most of the root probe's items were based on the Live Oak tree. An in-depth, clinical interview-based analysis was conducted with 12 of those tested students. A team of root experts participated by designing, validating and answering the same questions that the students were asked. A "systems" lens as defined by a team of college instructors, root experts (Shigo, 1991), and this researcher was used to interpret the results. A correlational coefficient determining students' level of understanding of the root system and their level of understanding of the process of photosynthesis was established by means of Pearson's r correlation (r = 0.328) using the SAS statistical analysis (SAS, 1987). From this a coefficient of determination (r2 = 0.104) was determined. Students' level of understanding of the Live Oak root system (mean score 5.94) was not statistically different from their level of understanding of the process of photosynthesis (mean score 5.54) as assessed by the root probe, t (129) = 0.137, p > 0.05 one tailed-test. This suggests that, to some degree, level of the root system limits level of understanding of photosynthesis and vice versa. Analysis of quantitative and qualitative

Full Text Available Two studies examined children’s developing understanding of Aesop’s fables in relation to reading comprehension and to theory of mind. Study 1 included 172 children from Junior Kindergarten through Grade 6 in a school-wide examination of the relation between reading comprehension skills and understanding of Aesop’s fables told orally. Study 2 examined the relation between theory of mind and fables understanding among 186 Junior (4-year-old and Senior (5-year-old Kindergarten children. Study 1 results showed a developmental progression in fables understanding with children’s responses becoming increasingly decontextualized as they were able to extract the life lesson. After general vocabulary, passage comprehension predicted fables understanding. Study 2 results showed a relation between young children’s theory of mind development and their understanding of fables. After general vocabulary, second-order theory of mind predicted children’s fables understanding. Findings point to the importance of developing mental state awareness in children’s ability to judge characters’ intentions and to understand the deeper message embedded in fables.

Studies on falls are reviewed. Little information exists on which social or psychologic factors predispose an older person to fall or to sustain a fall-related injury. Risk of falling appears to be greater among females, the cognitively impaired, and those who use hypnotics, tranquilizers, and diuretics. The potential significance of depression and senile dementia of the Alzheimer's type on the risk of falling is explored. It is suggested that because of the associated impaired judgment, distraction, and psychomotor retardation, the presence of either clinical condition may increase an individual's risk of falling. In the final section of the article, directions for future research are discussed. Development of a systematic research program is suggested including epidemiologic studies of all falls and of medically treated falls. Such studies should be multidisciplinary and include assessment of social and psychologic factors as well as physical and functional health status, ambulatory function, perceptual acuity, and the circumstances surrounding the fall. The psychologic consequences of falling, particularly in the absence of a serious fall-related injury, is identified as an important research area.

Fatigue negatively affects the performance of intensive care nurses. Factors contributing to the fatigue experienced by nurses include lifestyle, psychological status, work organization and sleep problems. To determine the level of fatigue among nurses working in intensive care units and the related factors. This descriptive study was conducted with 102 nurses working in intensive care units in the West Black Sea Region of Turkey. Data were collected between February and May 2014 using a personal information form, the Visual Analogue Scale for Fatigue (VAS-F), the Hospital Anxiety and Depression Scale and the Pittsburg Sleep Quality Index. The intensive care nurses in the study were found to be experiencing fatigue. Significant correlations were observed between scores on the VAS-F Fatigue and anxiety (p=0.01), depression (p=0.002), and sleep quality (p<0.001). Anxiety, depression and quality of sleep were significantly affected by the intensive care nurses' levels of fatigue. These results can be of benefit in taking measures which may be used to reduce fatigue in nurses, especially the fatigue related to work organization and social life.

Guided by the biopsychosocial framework and empirical evidence, this study examined protective and risk factors of older adults' suicidal thoughts and attempts during the previous month, 12 months, and 5 years. The data used in this study were extracted from the Sample Survey on Aged Population in Urban/Rural China conducted in 2006, which included 15,957 older adults from mainland China. Multiple penalized logistic regressions were used to conduct the analyses. During the previous month, 12 months, and 5 years, 5.1‰, 10.0‰, and 17.7‰ of older adults indicated that they thought about suicide, whereas 2.2‰, 3.5‰, and 6.3‰ reported suicidal attempts, respectively. Older adults' age, financial strain, functional limitations, depression, children's filial piety, social network, loneliness, and urban residence were significantly related to suicidal thoughts during the different time periods. In addition, older adults' religious affiliation, depression, loneliness, and urban residence were significantly related to suicidal attempts during the different time periods. Older adults' suicidal thoughts and attempts need to be assessed by mental health care professionals and primary care doctors. Programs addressing these important protective and risk factors may help reduce older adults' suicidal thoughts and attempts.

To determine the perceived quality variables related to satisfaction and to identify the influence of sociodemographic factors on user satisfaction with hospital emergencies. A telephone survey was conducted with a specifically designed questionnaire for use in a sample of 3,600 users of hospital emergency services in nine public hospitals in 2008 and 2009. The adjusted model including all perceived quality and sociodemographic variables explained 47.1% of the variance (adjusted R(2)). Of all the independent variables included, only eight were significant in predicting the level of patient satisfaction. These variables were related to the patient's opinion of the relationship with medical staff (p = 0.041), nurses' and porters' professionalism (p = 0.010 and 0.022), infrastructure (cleanliness and comfort) (p = 0.033 and 0.008), information received at discharge (p = 0.000), waiting time in the emergency department (p = 0.000) and the perception of treatment-diagnosis without failure (p = 0.028). The variables influencing emergency patients' satisfaction were determined, allowing areas where corrective action could be introduced to be identified. In addition, possible confounding factors that should be controlled for when comparing results among distinct hospitals were identified. The emergency satisfaction questionnaire is a useful instrument to evaluate and improve quality of care. Copyright © 2011 SESPAS. Published by Elsevier Espana. All rights reserved.

Recent work has demonstrated that math anxiety is more than just the product of poor math skills. Psychosocial factors may play a key role in understanding what it means to be math anxious, and hence may aid in attempts to sever the link between math anxiety and poor math performance. One such factor may be the extent to which individuals integrate math into their sense of self. We adapted a well-established measure of this degree of integration (i.e., self-other overlap) to assess individuals’ self-math overlap. This non-verbal single-item measure showed that identifying oneself with math (having higher self-math overlap) was strongly associated with lower math anxiety (r = -0.610). We also expected that having higher self-math overlap would leave one especially susceptible to the threat of poor math performance to the self. We identified two competing hypotheses regarding how this plays out in terms of math anxiety. Those higher in self-math overlap might be more likely to worry about poor math performance, exacerbating the negative relation between math anxiety and math ability. Alternatively, those higher in self-math overlap might exhibit self-serving biases regarding their math ability, which would instead predict a decoupling of the relation between their perceived and actual math ability, and in turn the relation between their math ability and math anxiety. Results clearly favored the latter hypothesis: those higher in self-math overlap exhibited almost no relation between math anxiety and math ability, whereas those lower in self-math overlap showed a strong negative relation between math anxiety and math ability. This was partially explained by greater self-serving biases among those higher in self-math overlap. In sum, these results reveal that the degree to which one integrates math into one’s self – self-math overlap – may provide insight into how the pernicious negative relation between math anxiety and math ability may be ameliorated.

Retrobulbar hematoma (RBH), a rare but serious condition, can result in permanent vision loss. Although it is a known complication following trauma or facial fracture reduction, sinus surgery, or blepharoplasty, factors related to patient outcomes are not well-defined. A systematic review was performed to determine the relation of patient/treatment factors to outcomes. Articles retrieved from a PubMed search (1989-2017) were reviewed. Demographic information, etiology, symptoms, and final vision outcomes were analyzed using Fisher's exact tests, single and multiple predictor logistic regression. Of 429 articles identified, 16 were included in the study. 93 cases of retrobulbar hematoma were included. 74% occurred after trauma, while 26% occurred postoperatively. Onset of symptoms occurred after approximately 24 hours. 28% received treatment within 1 hour, 54% within 1-24 hours, and 18% after 24 hours. 51% had complete visual recovery, while 27% had partial recovery, and 22% developed blindness. Older patients and patients who sustained trauma were less likely to have a full recovery (p = 0.029, p = 0.023). Increasing number of symptoms trended towards a prediction of blindness (p = 0.092). Surgical decompression and shorter time to treatment were each highly predictive of full recovery (p = 0.024, p = 0.003) and decreased likelihood of blindness (p = 0.037, p = 0.045); use of steroids was not found to be significant. Retrobulbar hematoma is a diagnostic and therapeutic emergency. Factors associated with improved outcomes include younger age, decreased number of total symptoms, surgical decompression, and shorter time to treatment. If recognized and treated early with surgical decompression, recovery of vision is possible. Copyright © 2017 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

The main complication of central venous catheter (CVC) in hemodialysis is infection. Identifying CVC related infection (CVC-RI) risk factors and causative micro-organisms is important for setting prevention policies. There were no data regarding CVC-RI in hemodialysis in Algeria. To determine rates of CVC-RI in hemodialysis in Setif university hospital, risk factors and causative microorganisms, we conducted a prospective study from November 2014 to May 2015 involving patients with CVC in hemodialysis. Micro-organisms isolated from semi quantitative culture of CVC and blood culture were identified and tested for antibiotic susceptibility using the automated MicroScan system (DADE Behring, Sacramento, CA, USA). Chi-square test was performed to compare demographic and clinical variables (age, sex, comorbidities, duration of CVC, insertion site) in the groups of patients with and without CVC-RI. P<0.05 was considered statistically significant. All analyses were performed using SPSS V17 for Windows statistical package (SPSS Inc., Chicago, IL, USA). 94 patients and 152 CVC procedures were analyzed. 34 CVC-RI were documented with an incidence of 16.6 per 1000 CVC-days. Incidence of CVC related bloodstream infection (CVC-RBI) was 10.8 per 1000 CVC-days. Independent risk factors associated with CVC-RI were diabetes (P=0.01) and duration of catheterization (P= 0.01). Causative micro-organisms were: Klebsiella pneumoniae 26.5%, coagulase-negative staphylococci 23.5% and Staphylococcus aureus 23.5%. Micro-organisms were multidrug-resistant (MDR). Mortality was statistically associated to inadequate antibiotic therapy. The duration of CVC should be reduced by creation of fistulas. More compliance to hygiene measure is needed for decreasing CVC-RI and resistance rate. Copyright © 2016 King Saud Bin Abdulaziz University for Health Sciences. Published by Elsevier Ltd.

Full Text Available Abstract Objective To assess factors associated with drug-related harms related to policing among injection drug users (IDUs in Tijuana, Mexico. Methods IDUs who were over 18 years old and had injected drugs within the last six months were recruited via respondent-driven sampling and underwent questionnaires and testing for HIV (human immunodeficiency virus, syphilis and TB (tuberculosis. Random effects logistic regression was used to simultaneously model factors associated with five drug-related harms related to policing practices in the prior six months (i.e., police led them to rush injections; affected where they bought drugs; affected locations where they used drugs; feared that police will interfere with their drug use; receptive syringe sharing. Results Of 727 IDUs, 85% were male; median age was 38 years. Within the last 6 months, 231 (32% of IDUs reported that police had led them to rush injections, affected where they bought or used drugs or were very afraid police would interfere with their drug use, or shared syringes. Factors independently associated with drug-related harms related to policing within the last six months included: recent arrest, homelessness, higher frequencies of drug injection, use of methamphetamine, using the local needle exchange program and perceiving a decrease in the purity of at least one drug. Conclusions IDUs who experienced drug-related harms related to policing were those who were most affected by other micro and macro influences in the physical risk environment. Police education programs are needed to ensure that policing practices do not exacerbate risky behaviors or discourage protective behaviors such as needle exchange program use, which undermines the right to health for people who inject drugs.

Exposure to hypobaric hypoxia, a condition involving decreased availability of oxygen is known to be associated with oxidative stress, neurodegeneration and memory impairment. The multifactorial response of the brain and the complex signaling pathways involved therewith limits the therapeutic efficacy of several antioxidants in ameliorating hypobaric hypoxia-induced memory impairment. The present study was therefore aimed at investigating the potential of acetyl-l-carnitine (ALCAR), a known antioxidant that has been reported to augment neurotrophin-mediated survival mechanisms, in ameliorating hypoxia-induced neurodegeneration and memory impairment. Nuclear factor erythroid 2-related factor 2 (Nrf2) is a key transcription factor involved in the cellular defense mechanism against oxidative stress related to brain injury and neurological disorders. The study was designed to understand the mechanisms involving Nrf2 stabilization following exposure to hypobaric hypoxia. The results displayed reference memory impairment in Sprague-Dawley rats exposed to hypobaric hypoxia (7620 m) for 14 consecutive days which however improved on administration of ALCAR during hypoxic exposure. The study also revealed Nrf2 regulated augmented antioxidant response on administration of ALCAR which was through a novel tyrosine kinase A (TrkA) receptor-mediated mechanism. A decrease in free radical generation, lipid peroxidation and protein oxidation was also observed along with a concomitant increase in thioredoxin and reduced glutathione levels on administration of ALCAR during exposure to hypobaric hypoxia. The present study therefore reveals the therapeutic potential of ALCAR under conditions of hypobaric hypoxia and elucidates a novel mechanism of action of the drug.

Conclusions: Different factors were found to be associated with initiation and adherence of osteoporosis medication. Patient knowledge of their disease and the perception of barriers were found to be the most influential. Empowering patients with the knowledge to better understand their disease and decreasing the perception of barriers through education initiatives may be effective in improving patient outcomes.

Lattice QCD is an essential complement to the current and anticipated DOE-supported experimental program in hadronic physics. In this poster we address several key questions central to our understanding of the building blocks of nuclear matter, nucleons and pions. Firstly, we describe progress at computing the electromagnetic form factors of the nucleon, describing the distribution of charge and current, before considering the role played by the strange quarks. We then describe the study of transition form factors to the Delta resonance. Finally, we present recent work to determine the pion form factor, complementary to the current JLab experimental determination and providing insight into the approach to asymptotic freedom

This paper aims to explore the role of factors pertaining to trust in real-world automation systems through the application of observational methods in a case study from the railway sector. Trust in automation is widely acknowledged as an important mediator of automation use, but the majority of the research on automation trust is based on laboratory work. In contrast, this work explored trust in a real-world setting. Experienced rail operators in four signaling centers were observed for 90 min, and their activities were coded into five mutually exclusive categories. Their observed activities were analyzed in relation to their reported trust levels, collected via a questionnaire. The results showed clear differences in activity, even when circumstances on the workstations were very similar, and significant differences in some trust dimensions were found between groups exhibiting different levels of intervention and time not involved with signaling. Although the empirical, lab-based studies in the literature have consistently found that reliability and competence of the automation are the most important aspects of trust development, understanding of the automation emerged as the strongest dimension in this study. The implications are that development and maintenance of trust in real-world, safety-critical automation systems may be distinct from artificial laboratory automation. The findings have important implications for emerging automation concepts in diverse industries including highly automated vehicles and Internet of things.

Context: Men entering the nursing profession have been investigated from several different perspectives. Due to male gender characteristics and existing public image, nursing is often not considered as a career choice by men. Whether nursing would benefit from increased number of men is a key question in the literature. The purpose of this integrative review of the literature was to identify factors influencing men to enter the nursing profession. In addition, it sought to understand the challenges they are confronted within this profession. Evidence Acquisition: A systematic search of the existing literature was performed using an Internet search with broad keywords to access related articles in both Persian and English databases. Finally, 34 studies (written between 2000 and early 2013) were selected and surveyed. Results: Most of the studies were conducted in developed counties. The review identified reasons why males choose nursing, and other challenges facing men entering and working in nursing. Themes that emerged from the literature include educational and societal barriers experienced by men in nursing, recruitment, career choice, and role strain. Conclusions: Regarding men’s influences on professional development, and also the importance of gender-based caring, policies for recruitment and retention of men in nursing must be followed hastily. However, there is a need for further research regarding the challenges faced by men entering nursing, in both Iran and other developing countries. PMID:25414879

To determine quality of life (QoL) and its relationship to lifestyles in adolescents in high schools. Cross-sectional, observational study with 256 students aged 12 to 17 in Seville (Spain). Multiple linear regression models were tested (p <0.05). The boys had higher scores in most of the QoL areas. The female gender was inversely related to physical, psychological, familial QoL areas and the general QoL index. Family functionality and performing physical activity were the factors most associated with better QoL in all areas. All multivariate models were statistically significant and explained from 11% of social QoL variability to 35% of the general QoL index. The findings could be useful for developing interventions to promote health in schools, with the objective of promoting healthy lifestyles and QoL. Copyright © 2016 SESPAS.

Full Text Available INTRODUCTION: The length of time that it takes an orthodontist to treat adult patients varies widely. OBJECTIVE: The aim of this study was to investigate how different variables influence treatment time. METHODS: Seventy clinical case reports of successfully treated adult patients were examined. The patients were selected from 4,723 records held by three experienced orthodontists. The influence exerted by the following variables on treatment time was assessed: age, sex, facial pattern, severity of malocclusion (measured by the PAR index, sagittal relationship of canines, type of brackets (ceramic or metal, tooth extractions, missed appointments and orthodontic appliance issues/breakages, the latter being the dependent variable. Assessment was performed by multiple linear regression analysis, followed by the stepwise method with P < 0.05. RESULTS: The number of times a patient missed their appointment (no-show (R² = 14.4%, p < 0.0001 and the number of appliance issues/breakages (R² = 29.71%, p = 0.0037 significantly affected variability in treatment time, and these two variables together can predict 43.75% (R² total of the overall variability in treatment time. Other factors, such as canine relationship at the beginning of treatment, bracket type (metal or ceramic, tooth extractions, age at start of treatment, severity of the initial malocclusion, sex and facial pattern had no significant bearing on treatment time. CONCLUSIONS: The duration of orthodontic treatment in adults, when performed by experienced orthodontists, is mainly influenced by factors related to patient compliance. However, several factors which were not included in this study may contribute to variability in orthodontic treatment time.

Periodontal diseases have a multifactorial etiology and their risk factors are influenced by modifiable and nonmodifiable factors. The information on periodontal disease and associated risk factors in the Vietnamese population is sparse. Vietnamese dental patients are specific groups with high dental needs and often have greater overall oral health problems. Thus, the purpose of this study was to examine the relationships of periodontal disease to sociodemographic, health-behavioural, and biological characteristics in Vietnamese dental patients. A sample of 243 subjects was selected from the National Hospital of Odonto-Stomatology in Hochiminh City. The sociodemographic and health-behavioural characteristics were investigated by a questionnaire. Oral examination including dental and periodontal conditions was conducted. Bacterial load in tongue coating and hemoglobin in saliva were assessed using the BANA test and Perioscreen test. The Perioscreen test showed moderate sensitivity (0.752) and specificity (0.746) to periodontal disease. The binary logistic regression analyses indicated that older subjects (OR = 2.5), or those who did not frequently visit a dentist (OR = 4.1), brushed their teeth only once a day (OR = 2.5), did not use dental floss (OR = 2.9), were past smokers (OR = 3.1), current smokers (OR = 4.1), or had positive BANA test results (OR = 12.0) were more likely to have periodontal disease. The results revealed the periodontal disease was related to age, dental visit behaviour, smoking behaviour, frequency of tooth brushing, use of dental floss, bacterial load in the tongue coating, and hemoglobin in saliva.

Full Text Available The paper examines the issue of assessing the extent of precarious labour relations considered by the authors as one of the systemic factors of social pollution. The emergence of the social pollution of the labour sphere is primarily caused by the aspiration of employers to reduce labour costs. It leads to an increasing spread of the use of toxic practices of the personnel management. This article presents the interim results of the monitoring study, implemented by the authors on the basis of the methodology which includes the sociological survey of the employees of Russian enterprises of different economic sectors. In 2014, the authors held a pilot study in order to test the methodological tools of the evaluation of social pollution level in labour sphere including the assessment of the degree of precarious labour relations as well as verification of the hypothesis of this research. Following the results of the pilot study, the sociological survey tools were improved. The survey took place in 2015 among workers of the Sverdlovsk region. The obtained results allow us to identify the toxic elements of labour sphere. These elements are associated with the precarious labour relations and have a negative impact on the physical and psychosocial health of employees. Also, we can make conclusions about the existing trends that reflect the qualitative characteristics of current changes in the relationship between employers and employees. The limitations of the presented results are conditioned by the fact that the monitoring assumes conducting annual surveys for a long period. However, the interim findings are of interest and can be used to find solutions of the problems caused by the increasing precarious labour relations both at the level of enterprise and at the level of regional power.

Despite the huge body of research on social support, literature has been primarily focused on its beneficial role for both physical and mental health. It is still unclear why people with mental and neurological disorders experience low levels of social support. The main objective of this study was to explore what are the strongest factors related to social support and how do they interact with each other in neuropsychiatric disorders. The study used cross-sectional data from 722 persons suffering from dementia, depression, epilepsy, migraine, multiple sclerosis, Parkinson's disease, schizophrenia, stroke, and substance use disorders. Multiple linear regressions showed that disability was the strongest factor for social support. Extraversion and agreeableness were significant personality variables, but when the interaction terms between personality traits and disability were included, disability remained the only significant variable. Moreover, level of disability mediated the relationship between personality (extraversion and agreeableness) and level of social support. Moderation analysis revealed that people that had mental disorders experienced lower levels of support when being highly disabled compared to people with neurological disorders. Unlike previous literature, focused on increasing social support as the origin of improving disability, this study suggested that interventions improving day-to-day functioning or maladaptive personality styles might also have an effect on the way people perceive social support. Future longitudinal research, however, is warranted to explore causality.
Full Text Available Background: the aging process causes decreasing in the function of various organs. Skletal muscle is one of the organs affected by aging process. It is known as sarcopenia. Sarcopenia is defined as a syndrome characterized by progressive loss of muscle mass and strength. The handgrip strength examination is often applied as a sarcopenia filtering technique. This study aimed to determine the relationship between age, nutritional status, and chronic diseases such as stroke, hypertension (HT, diabetes mellitus (DM, coronary heart disease (CHD, and chronic obstructive pulmonary disease (COPD with handgrip strength. Methods: a cross-sectional study to determine factors related to the handgrip strength in elderly patients was conducted in Geriatric outpatient clinic of Cipto Mangunkusumo Hospital and Mohammad Hoesin Hospital from August to October 2015. There were 352 eligible subjects in this study recruited with consecutive sampling. The independent variables in the study consisted of age, sex, nutritional status, chronic disease (stroke, hypertension (HT, diabetes mellitus (DM, coronary heart disease (CHD and chronic obstructive pulmonary disease (COPD, waist circumference while the dependent variable was handgrip strength. Results: age of more than 75 years old and malnutriton were risk factors that affected hangrip strength. Age of >75 years increase the risk for having low handgrip strength by 2,3-fold. Malnutrition increased risk for low handgrip strength for 1,9-fold. Conclusion: ages of >75 years old and malnutrition will increase the risk of low handgrip strength in elderly patients.

Unprecedented escalation of secular and religious cults has necessitated further inquiry into more precise conditions under which individuals develop vulnerability and become converted by these groups. The present discussion focuses on a number of factors which seem to influence individuals' susceptibility and recruitment by cults. These variables include (a) generalized ego-weakness and emotional vulnerability, (b) propensities toward dissociative states, (c) tenuous, deteriorated, or nonexistent family relations and support systems, (d) inadequate means of dealing with exigencies of survival, (e) history of severe child abuse or neglect, (f) exposure to idiosyncratic or eccentric family patterns, (g) proclivities toward or abuse of controlled substances, (h) unmanageable and debilitating situational stress and crises, and (i) intolerable socioeconomic conditions. Also presented are methods utilized by cults, e.g., intimidation, coercion, and indoctrination, for systematically recruiting, initiating, and influencing inductees. More careful attention to these factors might help health care providers, educators, clergy, and concerned family and friends determine more precisely individuals at greater risk for recruitment into cults.
Full Text Available Background and Aim: Tuberculosis is one the major health care problems in developing countries. Miliary tuberculosis is induced by blood dissemination of multiple tubercle bacilli, the paramount importance of accurate diagnosis of military tuberculosis is because of its dismal outcome if untreated and the chance of cure if diagnosis happens early in the course of the disorder. In this study we describe the demographic and risk factors related to military tuberculosis, which enables us to control and reduce the incidence of military tuberculosis. This ultimately reduces the mortality and morbidity consistent with this disorder. Materials and Methods: we conducted a retrospective case control study, which compares 28 patients with military tuberculosis and 56 patients with pulmonary tuberculosis as control. We reviewed all the patients' documents registered between years 1994-2004, after extracting raw data we analyzed them with chi-square and Fisher exact tests. Results and Conclusion: We found that HIV (P< 0.05 infection and lack of BCG vaccination (P< 0.05 increases the number of military tuberculosis among our patients. In addition we did not find any other significant risk factor.

INTRODUCTION: The aim of present research was to determine the independent prognostic value and the 3 and 5 years survival of more significant clinicopathological prognostic factors and in each stage, according to pathological staging system of tumor-nodule-metastasis (TNM) in patients with cutaneous malignant melanoma (CMM). METHODS: A longitudinal, descriptive and retrospective study was conducted applying the Cox proportional risk form and the Kaplan-Meier method, aimed to search of different risk variables in patients with CMM. We studied 157 patients with CMM, seen during 8 years (1993 to 2001), diagnosed and treated in National Institute of Oncology and Radiobiology of La Habana. RESULTS: The more powerful prognostic variables related to localized disease (stage I and II) were the Breslow density (P: 0,000), the mitosis rate (P: 0,004), and the Clark level (P: 0,04); among the variables related to the regional disease (stage III) the number of lymphatic ganglia involved was the more weighthy (P:0,000) and the more important in Stage IV was the distant visceral metastasis (P:0,003). Survival was decreasing according to the advance of the pathological stage of disease. CONCLUSIONS: The more involved independent prognostic factors were the Breslow rate, the number of involved regional lymphatic nodules and the distant visceral metastasis, which is endorsed by a world consensus. However, variables as age, sex, lesion site, ulceration, host-tumor inflammatory response, histological subtype, satellitosis and transient metastasis, considered as independent prognostic indicators in big casuistries, had not statistical significance in present paper.

Communication success under adverse conditions requires efficient and effective recruitment of both bottom-up (sensori-perceptual) and top-down (cognitive-linguistic) resources to decode the intended auditory-verbal message. Employing these limited capacity resources has been shown to vary across the lifespan, with evidence indicating that younger adults out-perform older adults for both comprehension and memory of the message. This study examined how sources of interference arising from the speaker (message spoken with conversational vs. clear speech technique), the listener (hearing-listening and cognitive-linguistic factors), and the environment (in competing speech babble noise vs. quiet) interact and influence learning and memory performance using more ecologically valid methods than has been done previously. The results suggest that when older adults listened to complex medical prescription instructions with “clear speech,” (presented at audible levels through insertion earphones) their learning efficiency, immediate, and delayed memory performance improved relative to their performance when they listened with a normal conversational speech rate (presented at audible levels in sound field). This better learning and memory performance for clear speech listening was maintained even in the presence of speech babble noise. The finding that there was the largest learning-practice effect on 2nd trial performance in the conversational speech when the clear speech listening condition was first is suggestive of greater experience-dependent perceptual learning or adaptation to the speaker's speech and voice pattern in clear speech. This suggests that experience-dependent perceptual learning plays a role in facilitating the language processing and comprehension of a message and subsequent memory encoding. PMID:26106353

The purpose of this study was to further understand the health promotion behaviors of Korean goose mothers in the North America area. Health promotion behaviors measured in this study were self-actualization, health responsibility, physical activity, nutrition, interpersonal relations, and stress management. The study is part of a larger study which used surveys (N=140) and in-person interviews (n=18). In this study, analysis of survey results is presented. Advertisements and snowballing technique were used to recruit study participants. Pearson's correlation was used to explore the relationships between health promotion and social support, acculturation attitudes, and perceived family health. Multiple regressions were used to examine the predictors of health promotion behaviors. Women in the study were most frequently engaging in self-actualization and least in physical activity. Physical activity did not correlate with any of the study variables. When multiple regressions were performed, the model for each health promotion behavior was found to be statistically significant except for that of physical activity. Overall, study variables worked differently across models. Social support predicted self-actualization, health responsibility, interpersonal relations, and stress management. None of the acculturation attitudes predicted health promotion behaviors. The subdimensions of perceived family health predicted health promotion behaviors except physical activity. The findings of this study contributed to the body of knowledge of health promotion among international migrant populations by identifying the differential effects of social support, acculturation attitudes, and perceived family health for six areas of health promotion.

Background: Musculoskeletal disorders (MSDs) encompass a series of debilitating diseases with high incidence and prevalence, representing a high economic and social cost. Prevention is crucial, so is of great interest to determine modifiable risk factors, such as those related to lifestyle. Methods: A descriptive cross-sectional study was performed in 91 patients selected by systematic random sampling and were divided into three experimental groups according to the cause and evolution of its MSD (neck pain, knee pain and back pain). A biometric measurement, nutritional assessment, physical and occupational activity, muscle balance and oxidative status was performed. Results: The female is the most affected gender by the presence of musculoskeletal injuries such as neck pain and back pain. Overall, most patients (67.4%) had normal weight, overweight 24.41% and only 8.1% were obese type I. Patients with neck pain are the group doing less physical activity and worse muscular balance present. Oxidative stress was higher in patients with knee pain than in the other groups. Regarding the consumed diet, differences between experimental groups on the mineral content (Zn, Mn, Se and I) and vitamins (folate and ascorbic acid) are observed. Conclusions: Cholecalciferol intake and vitamins A and D is less than those recommended in all subjects, which promotes muscle disease. Folate intake was below recommendations, increasing susceptibility to oxidative stress. Obesity and oxidative stress related to the prevalence of the different types of MSDs studied.

To assess changes in subjective fatigue symptoms of adolescent girls over a 15-year period and investigate factors related to these symptoms. A total of 86 items on physical health (including subjective fatigue symptoms), dietary life, and daily living were investigated and five items on physical activity were measured for approximately 100 female first-year dietetic students at a junior college each October over the 15-year period from 1994 to 2008. A total of 1,547 students (mean age, 19.2 +/- 0.3 years) were studied. Subjects were first divided into two groups using the median subjective fatigue score as the cutoff point, and annual changes in the proportion of students in the high subjective fatigue group were investigated by simple regression analysis. In addition, relationships between the two subjective fatigue groups and each item were investigated. 1) The proportion of students with many subjective fatigue symptoms showed a significantly increasing trend over the 15-year period. 2) Investigation of relationships between subjective fatigue symptoms and each factor revealed significance for many items, including dietary habits, life satisfaction, amount of sleep, and desire for a positive body image. 3) In order to determine which of the items were most strongly related to subjective fatigue symptoms, multiple logistic regression analysis was performed for the 15-year period as well as three 5-year periods into which it was divided. The results showed that the dietary habits score (an indicator of dietary habits) and life satisfaction were related to subjective fatigue symptoms during all four periods. As for other items, relationships were observed for amount of sleep in three, diet and salt intake score in two, and liking for coffee/tea, juice drinks, and oily food, bedtime snack, desire for body image, self-assessment of body type, and health consciousness in one. These findings indicate that perspectives in education for promoting the health of

Subjects with abdominal obesity show several signs of a perturbed regulation of the hypothalamic-pituitary-adrenal (HPA) axis. This is known to occur after chronic, submissive stress. Perceived environmental stress is depending on personality characteristics. Therefore, personality disorders (PD:s) were examined in relation to HPA axis status, other endocrine and metabolic variables as well as anthropometry. Men (no.=284) aged 51 years, recruited in similar subgroups of low, median and high waist/hip circumference ratio (WHR) from a sample of 1302 men. Measurements of personality disorders by Structured Clinical Interview for DSM-III-R, Axis II (SCID II), body mass index (BMI, weight, kg/height2, m2), WHR and abdominal sagittal diameter (D), dexamethasone suppression test (0.5 mg, salivary measurements of cortisol), insulin-like growth factor I (IGF-I), testosterone and metabolic variables. Men with cluster A (paranoid, schizotypal, schizoid) PD showed an increased BMI, WHR and D, independent of dexamethasone suppression. Testosterone was decreased in these men in relation to a blunted dexamethasone suppression. BMI, WHR and D were increased in men with cluster B (borderline, histrionic, narcissistic) and cluster C (avoidant, dependent, obsessive compulsive, passive aggressive) PD, only in relation to a blunted dexamethasone suppression. Furthermore, IGF-I was low in cluster B. Metabolic variables were differently associated to clusters of PD but generally followed obesity. Path-analytic models suggested that cluster B and C PD were followed by blunted dexamethasone suppression and obesity. Men with cluster A PD showed centralized body fat distribution, independently of dexamethasone suppression. In contrast, men with impulsive (cluster B) and anxious (cluster C) personality disorders seem often to have abdominal obesity only in combination with a blunted dexamethasone suppression test, suggesting a HPA axis disturbance. These results suggest that PD:s are involved

Among Canadian youth, injury is the most common reason for presentation to the emergency department. Youth who commonly engage in multiple risk-taking behaviours are at greater risk for injury, but is it unknown if this phenomenon is more pronounced in different contexts. We aimed to study relationships between risk-taking behaviours and injury, and variations in such relationships between different environmental and social contexts, among youth in Canada. Risk-taking behaviour and injury outcome data were collected from grade 9 to 10 students using the 2009-2010 (Cycle 6) of the Health Behaviour in School-Aged Children Survey (n=10,429). Principal components analysis was used to identify clusters of risk-taking behaviours. Within each identified cluster, the degree of risk-taking was categorized into quartiles from lowest to highest engagement in the behaviours. Risk ratios with 95% confidence intervals were calculated to determine the association between the risk of any injury and the degree of risk-taking behaviour specific to the cluster. Clusters were then examined across home, school, neighbourhood and sport contexts. Four clusters of risk-taking behaviour were identified which were labelled as "gateway substance use", "hard drugs and weapons", "overt risk-taking", and "physical activity". Each cluster was related to injury occurrence in a graded fashion. Clusters of risk behaviour were most strongly associated with injuries sustained in neighbourhood settings, and expectedly, increasing physical activity behaviours were associated with increased risk of sport injuries and injuries occurring at school. This study furthers understanding of clustered risk-taking phenomena that put youth at increasing levels of injury risk. Higher risks for injury and associated gradients were observed in less structured contexts such as neighbourhoods. In contrast, clustered physical activity behaviours were most related to school injury or sport injury and were more likely to

This paper analyzes the different types of organization factors which influence the system safety. The organization factor can be divided into the interior organization factor and exterior organization factor. The latter includes the factors of political, economical, technical, law, social culture and geographical, and the relationships among different interest groups. The former includes organization culture, communication, decision, training, process, supervision and management and organization structure. This paper focuses on the description of the organization factors. The classification analysis of the organization factors is the early work of quantitative analysis. (authors)

Ecologists have had limited success in understanding which introduced species may become invasive. An evolutionary model is used to investigate which traits are associated with invasiveness. Translocation experiments were simulated in which species were moved into similar but evolutionary younger...... observed to be species and community combination specific. This evolutionary study represents a novel in silico attempt to tackle invasiveness in an experimental framework, and may provide a new methodology for tackling these issues....

To observe plasma vascular endothelial growth factor(VEGF) levels and related factors in patients with unstable angina pectoris(UAP). A total of 108 consecutive patients with chest pain hospitalized in our department from October to December 2014 were included. They were divided into UAP (n=78) and non-CHD group (n=30) by the result of coronary angiography(CAG). Coronary artery lesion was assessed according to the Gensini score, serum lipids, homocysteine(Hcy) levels and other biochemical indicators were also determined. The peripheral arterial tonometry was evaluated by reactive hyperemia index(RHI) measured by Endo-PAT2000 Noninvasive Diagnostic System.The level of plasma VEGF was detected in patients with unstable angina pectoris. Multiple linear regression analysis was used to analyze the correlations between VEGF and various related factors. Percent of male gender, triglyceride (TG) and Hcy levels were significantly higher in UAP group than in no-CHD group(all Punstable angina pectoris, and VEGF level is significantly associated with the degree of coronary artery stenosis, Gensini score and RHI. V EGF level might serve as a new biochemical indicator for coronary artery lesion in patients with UAP.

There is growing interest in characterising factors associated with positive regulatory outcomes for drug marketing authorisations. We assessed empirical studies published over the past 15 years seeking to identify predictive factors. Factors were classified to one of four 'factor clusters': evidentiary support; product or indication characteristics; company experience or strategy; social and regulatory factors. We observed a heterogeneous mix of technical factors (e.g., study designs, clinical evidence of efficacy) and less studied social factors (e.g., company-regulator interactions). We confirmed factors known to be of relevance to drug approval decisions (imperative) and a cohort of less understood (compensatory) social factors. Having robust supportive clinical evidence, addressing rare or serious illness, following scientific advice and prior company experience were associated with positive outcomes, which illustrated the multifactorial nature of regulatory decision making and factors need to be considered holistically while having varying, context-dependent importance.

Comorbidity challenges the notion of mental disorders as discrete categories. An increasing body of literature shows that symptoms cut across traditional diagnostic boundaries and interact in shaping the latent structure of psychopathology. Using exploratory and confirmatory factor analysis, we reveal the latent sources of covariation among nine measures of psychopathological functioning in a population-based sample of 13024 Finnish twins and their siblings. By implementing unidimensional, multidimensional, second-order, and bifactor models, we illustrate the relationships between observed variables, specific, and general latent factors. We also provide the first investigation to date of measurement invariance of the bifactor model of psychopathology across gender and age groups. Our main result is the identification of a distinct "Body" factor, alongside the previously identified Internalizing and Externalizing factors. We also report relevant cross-disorder associations, especially between body-related psychopathology and trait anger, as well as substantial sex and age differences in observed and latent means. The findings expand the meta-structure of psychopathology, with implications for empirical and clinical practice, and demonstrate shared mechanisms underlying attitudes towards nutrition, self-image, sexuality and anger, with gender- and age-specific features.

Neurobiological models of addiction posit that drug use can alter reward processes in two ways: (1) by increasing the motivational relevance of drugs and drug-related cues and (2) by reducing the motivational relevance of non-drug-related rewards. Here, we discuss the results from a series of neuroimaging studies in which we assessed the extent to which these hypotheses apply to nicotine dependence. In these studies, we recorded smokers’ and nonsmokers’ brain responses to a wide array of motivationally relevant visual stimuli that included pleasant, unpleasant, cigarette-related, and neutral images. Based on these findings, we highlight the flaws of the traditional cue reactivity paradigm and we conclude that responses to non-drug-related motivationally relevant stimuli should be used to appropriately gauge the motivational relevance of cigarette-related cues and to identify smokers attributing higher motivational relevance to drug-related cues than to non-drug-related rewards. Identifying these individuals is clinically relevant as they achieve lower rates of long-term smoking abstinence when attempting to quit. Finally, we show how this approach may be extended beyond nicotine dependence to inform theoretical and clinical research in the study of obesity. The cue reactivity paradigm (ie, comparing responses evoked by drug-related cues to those evoked by neutral cues) cannot provide conclusive information about the motivational relevance of drug-related cues. Responses to non-drug-related motivationally relevant stimuli should be used to appropriately gauge the level of motivational relevance that substance-dependent individuals attribute to drug-related cues. © The Author 2017.

Full Text Available Emerging evidence suggests that many of the clinical constructs used to help understand and explain obsessive-compulsive (OC symptoms, and negative mood, may be causally interrelated. One approach to understanding this interrelatedness is a motivational systems approach. This approach suggests that rather than considering clinical constructs and negative affect as separable entities, they are all features of an integrated threat management system, and as such are highly coordinated and interdependent. The aim of the present study was to examine if clinical constructs related to OC symptoms and negative mood are best treated as separable or, alternatively, if these clinical constructs and negative mood are best seen as indicators of an underlying superordinate variable, as would be predicted by a motivational systems approach. A sample of 370 student participants completed measures of mood and the clinical constructs of inflated responsibility, intolerance of uncertainty, not just right experiences, and checking stop rules. An exploratory factor analysis suggested two plausible factor structures, one where all construct items and negative mood items loaded onto one underlying superordinate variable, and a second structure comprising of five factors, where each item loaded onto a factor representative of what the item was originally intended to measure. A confirmatory factor analysis showed that the five factor model was preferential to the one factor model, suggesting the four constructs and negative mood are best conceptualized as separate variables. Given the predictions of a motivational systems approach were not supported in the current study, other possible explanations for the causal interrelatedness between clinical constructs and negative mood are discussed.

The main objective of this study is to assess the Breastfeeding Duration, Exclusive Breastfeeding Duration and other related factors among children aged less than 5 years old in rural areas of Northern Iran. This is a descriptive cross-sectional conducted on 2520 children aged 6-60 months (male: 1309, female: 1211) chosen by cluster random sampling from 20 out of 118 villages. Data were collected from mothers using a questionnaire. The duration of breastfeeding was computed only for children aged over 24 months old. Breastfeeding duration and Exclusive Breastfeeding Duration were classified based on WHO definition. SPSS Version 16 was used for data analysis. The mean Exclusive Breastfeeding Duration was 5.59 months, while 66.4% of children had exclusive breastfeeding for at least 6 months. The lowest Exclusive Breastfeeding Duration and the highest Breastfeeding Duration were observed among the Turkman ethnic group. Exclusive Breastfeeding duration of at least 5 months was 14.6%, thus the results were significantly higher than in the Turkman ethnic group (p=0.001). Meanwhile, the results showed that exclusive breastfeeding duration significantly increased with maternal education level (p=0.004). The study found that the mean breastfeeding duration was 20.6 months, and 89.3% and 74.7% of children were breastfed for at least 18 and 24 months, respectively. A positive correlation was reported between breastfeeding duration and family size, birth order, maternal age and children nutritional status, (p<0.05). Additionally, lactation period in underweight children was significantly higher than in obese children, (p=0.023). The study found that two-thirds of children exclusively breastfed during the first six months of life and the mean breastfeeding duration was 20.6 months. While both exclusive breastfeeding duration and breastfeeding duration were influenced by socio-demographic factors in the rural areas of Northern Iran.

Prisoner's addiction is one of the major problems in many countries which imposes very high medical costs and social harm to communities. This study investigated the pattern of substance use and related factors in male prisoners in one of the prisons in southeastern Iran. This cross-sectional study was carried out in 2016. The study population was inmates of a prison in southeast Iran. Sampling was carried out randomly according to the list of prisoners. Data were collected using a form and were analyzed with statistics software SPSS. More than four-fifths (75.3%) of the subjects consumed at least one substance (alcohol, tobacco and other drugs), 74.4% were smoking, 73.2% used a narcotic substance, and about one-fifth (19.3%) reported drinking alcohol. With a frequency of 62.0%, opium was the most frequently utilized narcotic substance. Poppy juice (31.6%), cannabis (29.8%), crystal (16.9%) and tramadol (16.9%) were the next frequent substances used. A percentage of 41.5% subjects reported using two or more drugs. A percentage of 80.7% subjects reported substance use among their friends, 39.2% by siblings and 37.2% by father. Regression analysis showed predictor variables of substance use were education, substance use by prisoner before being imprisoned, substance use by father, friends and siblings. This study showed a remarkable prevalence of substance use in prisons, which was more than general population. Therefore, it is necessary to consider alternative penalties of imprisonment due to the factors associated with substance use. Screening of people at high risk for substance use should be considered on admission to prison, and primary prevention measures should be focused on them.

This study identifies a number of sources of individual differences in SAT performance by examining the simultaneous contributions of factors from two otherwise disparate research areas, namely cognition/learning and social/personality. Preliminary analysis revealed that just the cognitive/learning measures accounted for 37.8, 41.4 and 21.9% of the variance in SAT, V-SAT and Q-SAT performance, respectively while just the social/personality measures accounted for 21.4, 18.2 and 17.3% of the variance. When combined, cognitive/learning and social/personality factors accounted for even larger amounts of variance in performance; specifically 43.4, 44.6 and 28% for the SAT, V-SAT and Q-SAT, respectively. Finally, the results revealed that three measures consistently predicted performance on the SAT, V-SAT and Q-SAT; two measures were the learning/cognitive factors of working memory and integration of new text-based information with information from long-term memory and one measure was the social/personality factor, test anxiety.

Previous physiological studies have identified factors that are involved in auto-PEEP generation. In our study, we examined how much auto-PEEP is generated from factors that are involved in its development. One hundred eighty-six subjects undergoing controlled mechanical ventilation with persistent expiratory flow at the beginning of each inspiration were enrolled in the study. Volume-controlled continuous mandatory ventilation with PEEP of 0 cm H2O was applied while maintaining the ventilator setting as chosen by the attending physician. End-expiratory and end-inspiratory airway occlusion maneuvers were performed to calculate respiratory mechanics, and tidal flow limitation was assessed by a maneuver of manual compression of the abdomen. The variable with the strongest effect on auto-PEEP was flow limitation, which was associated with an increase of 2.4 cm H2O in auto-PEEP values. Moreover, auto-PEEP values were directly related to resistance of the respiratory system and body mass index and inversely related to expiratory time/time constant. Variables that were associated with the breathing pattern (tidal volume, frequency minute ventilation, and expiratory time) did not show any relationship with auto-PEEP values. The risk of auto-PEEP ≥5 cm H2O was increased by flow limitation (adjusted odds ratio 17; 95% CI: 6-56.2), expiratory time/time constant ratio 15 cm H2O/L s (3; 1.3-6.9), age >65 y (2.8; 1.2-6.5), and body mass index >26 kg/m(2) (2.6; 1.1-6.1). Flow limitation, expiratory time/time constant, resistance of the respiratory system, and obesity are the most important variables that affect auto-PEEP values. Frequency expiratory time, tidal volume, and minute ventilation were not independently associated with auto-PEEP. Therapeutic strategies aimed at reducing auto-PEEP and its adverse effects should be primarily oriented to the variables that mainly affect auto-PEEP values. Copyright © 2016 by Daedalus Enterprises.
Given to the remarkable profitability of digital items in social virtual worlds (SVWs), such as SecondLife, Cyworld, and Habbo Hotel, it has become crucial to understand SVW users' postadoption behaviors toward digital items. This study develops a theoretical framework to examine key antecedents of users' intentions to repurchase and recommend digital items. Data collected from 256 users of digital items were empirically tested against the research model. The analysis results indicate that both user satisfaction and a perceived value play an important role in establishing users' postadoption intentions about digital items. Moreover, the results clearly show what roles perceived usefulness, perceived enjoyment, and perceived fee play in SVW environments.

Genetic testing is becoming increasingly available for adolescents who are undergoing cancer treatment or at risk of cancer predisposition syndromes. With this narrative review, we aimed to synthesize the evidence on psychosocial outcomes and adolescents' understanding of genetic testing-thus far, an underresearched topic. Both psychological benefits and harms of predictive testing were reported in adolescents from high-risk families. Harms were mainly related to cancer-specific distress and increased worries. Findings on genetic understanding were sparse. Future studies should focus on psychosocial outcomes and adolescents' understanding undergoing genetic testing and enabling access to genetic counseling pre-testing and post-testing.

As 7.8% of the U.S. population is affected by diabetes, health care providers are tasked with providing resources to assist patients toward self-management. Psychosocial issues have an effect on diabetes self-care. Diabetes-related distress is associated with self-management and lower A1C. This cross-sectional study seeks to understand how demographic factors, psychological orientations, support, and diabetes management behaviors predict diabetes-related distress. This study uses data from 267 adults with Type 2 diabetes. The Diabetes Distress Scale (DDS) is a 17-item scale measuring diabetes-related distress including emotional distress, physician-related distress, regimen distress, and interpersonal distress. Hierarchical regression was conducted in four stages. The final model explains 48% of the variance in DDS. Significant factors related to lower DDS were older age, lower body mass index, higher self-efficacy, higher levels of health care provider support, and a healthy diet. Findings of this study help health care providers know where to focus to reduce diabetes-related distress. Health care provider support is significant in reducing DDS. Diabetes education may want to include strategies that increase self-efficacy and assist people with diabetes to obtain a healthy weight through a more healthful diet.
Full Text Available The article is devoted to the study of factors influencing life satisfaction of teenagers raised in families as well as those raised in orphanages. Both groups are studied with regard to their self-attitude, self-confidence and relationships with significant adults. Sample: 96 teenagers aged between 14 and 16 years (46 of them live in or- phanages. Methods: Self-attitude methodology by S.R. Pantileev, Trust questionnaire by T.P. Skripkina, Child-parent relationships questionnaire by O.A. Karabanova and P.V. Troyanskaya, Life Satisfaction scale by E. Diner. The research proved the level of trust in orphanage-raised teenagers to be considerably lower than that of family-raised teenagers. The way teenagers see their relationships with significant adults also turned out to be fairly different in case of orphanage-raised groups due to their caregivers' authoritarian attitude towards them and lack of empathy and communication. The study also shows that the level of life satisfaction in the orphanage group is significantly below the average and substantially lower than in the group from family-raised teenagers. Positive self-attitude, person’s approval of his/ her intellectual capacities, as well as the caregiver's understanding of his pupil's features, are predictors of life satisfaction in the group of teenagers from orphanages. Concerning the family-raised teenagers, much more factors are involved in maintaining their subjective well-being.

Backyard trampolines are immensely popular among children, but are associated with an increase of trampoline-related injuries. The aim of this study was to evaluate radiographs of children with trampoline related injuries and to determine the risk factors. Between 2003 and 2009, 286 children under the age of 16 with backyard trampoline injuries were included in the study. The number of injuries increased from 13 patients in 2003 to 86 in 2009. The median age of the 286 patients was 7 years (range: 1-15 years). Totally 140 (49%) patients were males, and 146 (51%) females. Medical records and all available diagnostic imaging were reviewed. A questionnaire was sent to the parents to evaluate the circumstances of each injury, the type of trampoline, the protection equipment and the experience of the children using the trampoline. The study was approved by the Institutional Ethics Committee of the University Hospital of Bern. The questionnaires and radiographs of the 104 patients were available for evaluation. A fracture was sustained in 51 of the 104 patients. More than 75% of all patients sustaining injuries and in 90% of patients with fractures were jumping on the trampoline with other children at the time of the accident. The most common fractures were supracondylar humeral fractures (29%) and forearm fractures (25%). Fractures of the proximal tibia occurred especially in younger children between 2-5 years of age. Children younger than 5 years old are at risk for specific proximal tibia fractures ("Trampoline Fracture"). A child jumping simultaneously with other children has a higher risk of suffering from a fracture.

Previous research on the association between violence and biological stress regulation has been largely cross-sectional, and has also focused on childhood. Using longitudinal data from a low-income, high-risk, predominantly African-American sample (n = 266; 57 % female), we tested hypotheses about the influence of cumulative exposure to violence during adolescence and early adulthood on cortisol responses in early adulthood. We found that cumulative exposure to violence predicted an attenuated cortisol response. Further, we tested whether sex, mothers' support, or fathers' support moderated the effect of exposure to violence on cortisol responses. We found that the effect of cumulative exposure to violence on cortisol was modified by sex; specifically, males exposed to violence exhibited a more attenuated response pattern. In addition, the effect of cumulative exposure to violence on cortisol was moderated by the presence of fathers' support during adolescence. The findings contribute to a better understanding of how cumulative exposure to violence influences biological outcomes, emphasizing the need to understand sex and parental support as moderators of risk.

Background We present a bivariate twin analysis of anorexia nervosa (AN) and bulimia nervosa (BN) to determine the extent to which shared genetic and environmental factors contribute to liability to these disorders. Method Focusing on females from the Swedish Twin study of Adults: Genes and Environment (STAGE) (N=7000), we calculated heritability estimates for narrow and broad AN and BN and estimated their genetic correlation. Results In the full model, the heritability estimate for narrow AN was (a2 = .57; 95% CI: .00, .81) and for narrow BN (a2 = .62; 95% CI: .08, .70) with the remaining variance accounted for by unique environmental factors. Shared environmental factors estimates were (c2 = .00; 95% CI: .00, .67) for AN and (c2 = .00; 95% CI: .00, .40) for BN. Moderate additive genetic (.46) and unique environmental (.42) correlations between AN and BN were observed. Heritability estimates for broad AN were lower (a2 = .29; 95% CI: .04, .43) than for narrow AN, but estimates for broad BN were similar to narrow BN. The genetic correlation for broad AN and BN was .79 and the unique environmental correlation was .44. Conclusions We highlight the contribution of additive genetic factors to both narrow and broad AN and BN and demonstrate a moderate overlap of both genetic and unique environmental factors that influence the two conditions. Common concurrent and sequential comorbidity of AN and BN can in part be accounted for by shared genetic and environmental influences on liability although independent factors also operative.

Differences in social advantage significantly influence health conditions and life expectancy within any population. Such factors reproduce historic class, race, and ethnic disparities in community success. Few populations in the United States face more social and economic disadvantage than farmworkers, and farmworker housing has significant potential to ameliorate or amplify the health impact of those disadvantages. Drawing on the limited direct research on farmworkers, and on additional research about poor, isolated, and immigrant societies, we propose four mechanisms through which housing can be expected to affect farmworker health: quality of social capital within farmworker communities, stress effects of poor housing situations, effects of housing on social support for healthy behaviors, and interactions among these factors, especially effects on children that can last for generations. Policy and planning definitions of "adequate" farmworker housing should take a more holistic view of housing needs to support specific social and community benefits in design decisions. © The Author(s) 2015.

Asthma is complex and connected to a number of factors including access to healthcare, crime and violence, and environmental triggers. A mixed method approach was used to examine the experiences of urban people with asthma in controlling their asthma symptoms. The study started with an initial phase of qualitative interviews in West Philadelphia, a primarily poor African American community. Data from qualitative, semi-structured interviews indicated that stress, environmental irritants, and environmental allergens were the most salient triggers of asthma. Based on the interviews, the team identified six neighborhood factors to map including crime, housing vacancy, illegal dumping, tree canopy and parks. These map layers were combined into a final composite map. These combined methodologies contextualized respondents' perceptions in the framework of the actual community and built environment which tells a more complete story about their experience with asthma.

Kidney transplantation is the renal replacement therapy of choice for most patients with end-stage renal disease (ESRD), however, adherence to the recommended lifestyle is critical for a positive prognosis. The purpose of this study was to assess adherence to immunosuppressive therapy and lifestyle recommendations along with some related factors among kidney transplant patients. In this descriptive analytical study, all patients completed a questionnaire regarding medication intake and lifestyle recommendations (preventing of infection, self-monitoring, prevention of cardiovascular disease (CVD), and sun protection). The participants were divided into 4 groups according to the level of adherence (good, partial, poor, and nonadherent) indicated in their responses. Most kidney recipients were adherent to their drug prescriptions, but were partial, poor, or nonadherent regarding lifestyle recommendations. Increased passage of time since transplantation and low family support and educational level resulted in nonadherence. Men showed greater adherence to medication intake than women. Patients with lower number of drugs and reported drug side-effects illustrated better adherence to medication intake. Women adhered to infection protection recommendations more than men, and older and married patients adhered to cardiovascular prevention recommendations more than others. However, younger patients showed greater adherence to self-monitoring recommendations, and singles, young individuals, and women were adherent to sun protection recommendations. Nonadherence is common among kidney transplant recipients. Thus, it is necessary to determine patients who are at risk of nonadherence and to introduce more educational programs to improve their adherence and their quality of life (QOL).
Full Text Available Concerns that debt loads and other financial worries negatively affect student wellness are a top priority for many university administrators. Factors related to financial stress among college students were explored using the Roy Adaptation Model, a conceptual framework used in health care applications. Responses from the 2010 Ohio Student Financial Wellness Survey were analyzed using proportion tests and multivariate logistic regressions. The results show that financial stress is widespread among students – 71% of the sample reported feeling stress from personal finances. The results of the proportion tests and logistic regressions show that this study successfully identified important financial stressors among college students. Two of the most important financial stressors were not having enough money to participate in the same activities as peers and expecting to have higher amounts of student loan debt at graduation. The results also indicate that students with higher financial self-efficacy and greater financial optimism about the future are significantly less likely to report financial stress. Implications for student life administrators, policymakers, financial counselors, and financial therapists are discussed.

While the age, compliance, anisometropia degree, amblyopia degree and fixation behavior among three groups of patients had statistically significant differences(PCONCLUSION: There are closed relationship between comprehensive treatment effect and age, compliance, anisometropia degree, amblyopia degree, fixation behavior, but there is no significant correlation between anisometropia type and comprehensive treatment effect.
Full Text Available Abstract A cross-sectional study was conducted to identify the factors related to smoking habits of adolescents among secondary school boys in Kelantan state, Malaysia. A total of 451 upper secondary male students from day, boarding and vocational schools were investigated using a structured questionnaire. Cluster sampling was applied to achieve the required sample size. The significant findings included: 1 the highest prevalence of smoking was found among schoolboys from the vocational school; 2 mean duration of smoking was 2.5 years; 3 there were significant associations between smoking status and parents' smoking history, academic performance, perception of the health hazards of smoking, and type of school attended. Peer influence was the major reason students gave for taking up the habit. Religion was most often indicated by non-smokers as their reason for not smoking. Approximately 3/5 of the smokers had considered quitting and 45% of them had tried at least once to stop smoking. Mass media was indicated as the best information source for the students to acquire knowledge about negative aspects of the smoking habit. The authors believe an epidemic of tobacco use is imminent if drastic action is not taken, and recommend that anti-smoking campaigns with an emphasis on the religious aspect should start as early as in primary school. Intervention programs to encourage behavior modification of adolescents are also recommended.

Full Text Available Abstract Background Health insurance schemes have been widely introduced during this last decade in many African countries, which have strived for improvements in health service provision and the promotion of health care utilization. Client satisfaction with health service provision during the implementation of health insurance schemes has often been neglected since numerous activities take place concurrently. The satisfaction of enrollees and its influencing factors have been providing evidence which have assisted in policy and decision making. Our objective is to determine the enrollee's satisfaction with health service provision under a health insurance scheme and the factors which influence the satisfaction. Methods This retrospective, cross-sectional survey took place between May and September 2008. Two hundred and eighty (280 enrollees insured for more than one year in Zaria-Nigeria were recruited using two stage sampling. Enrollee's satisfaction was categorized into more satisfied and less satisfied based on positive responses obtained. Satisfaction, general knowledge and awareness of contribution were each aggregated and assessed as composite measure. Logistic regression analysis was used to analyze factors that influenced the satisfaction of enrollees. Results A high satisfaction rate with the health insurance scheme was observed (42.1%. Marital status (p Conclusions This study highlighted the potential effects of general health insurance knowledge and awareness of contributions by end-users (beneficiaries of such new program on client satisfaction which have significant importance. The findings provided evidence which have assisted the amendment and re-prioritization of the medium term strategic plan of operations for the scheme. Future planning efforts could consider the client satisfaction and the factors which influenced it regularly.

Factors leading to inappropriate critical care, that is treatment that should not be provided because it does not offer the patient meaningful benefit, have not been rigorously characterized. We explored medical record documentation about patients who received inappropriate critical care and those who received appropriate critical care to examine factors associated with the provision of inappropriate treatment. Medical records were abstracted from 123 patients who were assessed as receiving inappropriate treatment and 66 patients who were assessed as receiving appropriate treatment but died within six months of intensive care unit (ICU) admission. We used mixed methods combining qualitative analysis of medical record documentation with multivariable analysis to examine the relationship between patient and communication factors and the receipt of inappropriate treatment, and present these within a conceptual model. One academic health system. Medical records revealed 21 themes pertaining to prognosis and factors influencing treatment aggressiveness. Four themes were independently associated with patients receiving inappropriate treatment according to physicians. When decision making was not guided by physicians (odds ratio [OR] 3.76, confidence interval [95% CI] 1.21-11.70) or was delayed by patient/family (OR 4.52, 95% CI 1.69-12.04), patients were more likely to receive inappropriate treatment. Documented communication about goals of care (OR 0.29, 95% CI 0.10-0.84) and patient's preferences driving decision making (OR 0.02, 95% CI 0.00-0.27) were associated with lower odds of receiving inappropriate treatment. Medical record documentation suggests that inappropriate treatment occurs in the setting of communication and decision-making patterns that may be amenable to intervention.

An understanding of how health information technology (health IT) can contribute to sentinel events is necessary to learn how to safely implement and use health IT. An analysis was conducted to explore how health IT may contribute to adverse events that result in death or severe harm to the patient. For 3,375 de-identified sentinel events voluntarily reported to The Joint Commission between January 1, 2010, and June 30, 2013, categorical and keyword queries were used to search for potential health IT-related events. Each of the identified events was reviewed on the basis of findings from root cause analyses (RCAs) to determine if health IT contributed to or caused the event, and if so, how and why. The contributing factors were classified using a composite of existing classification schemes. A total of 120 health IT-related sentinel events (affecting 125 patients) were identified. More than half resulted in patient death, 30% resulted in unexpected or additional care, and 11% resulted in permanent loss of function. The three most frequently identified event types were (1) medication errors, (2) wrong-site surgery (including the wrong side, wrong procedure, and wrong patient), and (3) delays in treatment. Contributing factors were most frequently associated with the human-computer interface, workflow and communication, and clinical content-related issues. The classification of health IT-related contributing factors indicates that health IT-related events are primarily associated with the sociotechnical dimensions of human-computer interface, workflow and communication, and clinical content. Improved identification of health IT-related contributing factors in the context of the sociotechnical dimensions may help software developers, device manufacturers, and end users in health care organizations proactively identify vulnerabilities and hazards, ultimately reducing the risk of harm to patients.

In this study, we establish a set of 19 influential factors on the implementation of Green Supply Chain Management (GSCM) practices and analyse the interaction between these factors and their effect on the implementation of GSCM practices using the Interpretive Structural Modelling (ISM) method and the "Matrice d'Impacts Croisés Multiplication Appliquée à un Classement" (MICMAC) analysis on data compiled from interviews with supply chain (SC) executives based in the Gulf countries (Middle East region). The study reveals a strong influence and driving power of the nature of the relationships between SC partners on the implementation of GSCM practices. We especially found that dependence, trust, and durability of the relationship with SC partners have a very high influence. In addition, the size of the company, the top management commitment, the implementation of quality management and the employees training and education exert a critical influence on the implementation of GSCM practices. Contextual elements such as the industry sector and region and their effect on the prominence of specific factors are also highlighted through our study. Finally, implications for research and practice are discussed. Copyright © 2016 Elsevier Ltd. All rights reserved.

Full Text Available Hepatoma-derived growth factor-related protein-3 (Hdgfrp3 or HRP-3 was recently reported as a neurotrophic factor and is upregulated in hepatocellular carcinoma to promote cancer cell survival. Here we identified HRP-3 as a new endothelial ligand and characterized its in vitro and in vivo functional roles and molecular signaling. We combined open reading frame phage display with multi-round in vivo binding selection to enrich retinal endothelial ligands, which were systematically identified by next generation DNA sequencing. One of the identified endothelial ligands was HRP-3. HRP-3 expression in the retina and brain was characterized by Western blot and immunohistochemistry. Cell proliferation assay showed that HRP-3 stimulated the growth of human umbilical vein endothelial cells (HUVECs. HRP-3 induced tube formation of HUVECs in culture. Wound healing assay indicated that HRP-3 promoted endothelial cell migration. HRP-3 was further confirmed for its in vitro angiogenic activity by spheroid sprouting assay. HRP-3 extrinsically activated the extracellular-signal-regulated kinase ½ (ERK1/2 pathway in endothelial cells. The angiogenic activity of HRP-3 was independently verified by mouse cornea pocket assay. Furthermore, in vivo Matrigel plug assay corroborated HRP-3 activity to promote new blood vessel formation. These results demonstrated that HRP-3 is a novel angiogenic factor.

In the heavy oil industry, knowing oil properties is important to optimizing recovery, transport and refinery. Nitrogen, sulfur and oxygen compounds (NSOs) have an important impact on these properties but this is often overlooked. The purpose of this paper is to analyze the impact of functional groups in connection with heavy oil and asphaltenes. Experiments were carried out with asphaltenes altered by chemical surgery that removed specific functional interactions. Titration calorimetry and fluorescence spectroscopy were then done. Results highlighted the fact that functional groups are of key importance in the determination of heavy oil properties and that acidity can be considered the most important interaction. This paper demonstrated that the determination of specific interactions could be more important in assessing heavy oil properties than understanding their hydrocarbon structure; further work is needed to fully understand the role of sulfur and nitrogen species.

Methicillin-resistant Staphylococcus aureus (MRSA) remains one of the most important causes of nosocomial infections worldwide. Since the global spread of MRSA in the 1960s, MRSA strains have evolved with increased pathogenic potential. Notably, some strains are now capable of causing persistent infections not only in hospitalized patients but also in healthy individuals in the community. Furthermore, MRSA is increasingly associated with infections among livestock-associated workers, primarily because of transmission from animals to humans. Moreover, many MRSA strains have gained resistance to most available antibiotics. In this review, we will present current knowledge on MRSA epidemiology and discuss new endeavors being undertaken to understand better the molecular and epidemiological underpinnings of MRSA outbreaks.

Poor nutrition habits in adolescent girls endanger their health and are followed by serious systemic diseases in adulthood and negative effects on their reproductive health. To design health promotion programs, understanding of the intra- and interpersonal associated factors with treatment is essential, and this was the aim of this study. This cross-sectional study was conducted on 193 adolescent girls of age 11-15 years. Random cluster selection was used for sample selection. Food group consumption pattern was assessed by food frequency questionnaire. Also, perceived susceptibility/severity and nutritional attitude as intrapersonal factors and social support as interpersonal factor were assessed. The relationship between food group consumption level and nutritional attitude and perceived treat (susceptibility/severity) as intrapersonal factors and perceived social support as interpersonal factor were assessed by linear multiple regression and analysis of variance (ANOVA). Results showed that the level of sweetmeat food consumption was related to perceived social support (P = 0.03) and nutritional attitude (P = 0.01) negatively. In addition, an inverse and significant association was found between the level of junk food intake and informational perceived social support (P = 0.004). The association between the level of fast food intake and the perceived parental social support for preparation of healthy food was negatively significant (P = 0.03). Breakfast consumption was related to nutritional attitude (P = 0.03), social support (P = 0.03), and perceived severity (P = 0.045). Results revealed that perceived social support and nutritional attitude are the important and related factors in dietary intake among girls, and promotion of social support and modification of nutritional attitude may lead to healthy nutritional behaviors among them.

mHealth (mobile health) services are becoming an increasingly important form of information and communication technology (ICT) enabled delivery for healthcare, especially in low-resource environments such as developing countries like Bangladesh. Despite widespread adoption of mobile phones and the acknowledged potential of using them to improve healthcare services, the adoption and acceptance of this technology among the elderly is significantly low. However, little research has been done to draw any systematic study of the elderly's intention to adopt mHealth services. The aim of this study was to develop a theoretical model based on the Unified Theory of Acceptance and Use of Technology (UTAUT) and then empirically test it for determining the key factors influencing elderly users' intention to adopt and use the mHealth services. A face-to-face structured questionnaire survey method was used to collect data from nearly 300 participants of age 60 years and above from the capital city of Bangladesh. The data were analyzed using the Partial Least Squares (PLS) method, a statistical analysis technique based upon Structural Equation Modeling (SEM). The study determined that performance expectancy, effort expectancy, social influence, technology anxiety, and resistance to change (p0.05). This study confirms the applicability of UTAUT model in the context of mHealth services among the elderly in developing countries like Bangladesh. It provides valuable information for mHealth service providers and policy makers in understanding the adoption challenges and the issues and also provides practical guidance for the successful implementation of mHealth services. Additionally the empirical findings identify implications related to the design and development of mHealth services that influence potential users. Furthermore, due to a generic approach, the findings of this study could be easily modified to assist other developing countries in the planning and up-take of m

The incidence of type 2 diabetes has increased rapidly on a global scale. Beta-cell dysfunction contributes to the overall pathogenesis of type 2 diabetes. However, factors contributing to beta-cell function are not clear. The aims of this study were (i) to identify factors related to pancreatic beta-cell function and (ii) to perform mechanistic studies in vitro. Three specific measures of beta-cell function were assessed for 110 participants who completed an oral glucose tolerance test as part of the Metabolic Challenge Study. Anthropometric and biochemical parameters were assessed as potential modulators of beta-cell function. Subsequent in vitro experiments were performed using the BRIN-BD11 pancreatic beta-cell line. Validation of findings were performed in a second human cohort. Waist-to-hip ratio was the strongest anthropometric modulator of beta-cell function, with beta-coefficients of -0.33 (p = 0.001) and -0.30 (p = 0.002) for beta-cell function/homeostatic model assessment of insulin resistance (HOMA-IR), and disposition index respectively. Additionally, the resistin-to-adiponectin ratio (RA index) emerged as being strongly associated with beta-cell function, with beta-coefficients of -0.24 (p = 0.038) and -0.25 (p = 0.028) for beta-cell function/HOMA-IR, and disposition index respectively. Similar results were obtained using a third measure for beta-cell function. In vitro experiments revealed that the RA index was a potent regulator of acute insulin secretion where a high RA index (20ng ml-1 resistin, 5nmol l-1 g-adiponectin) significantly decreased insulin secretion whereas a low RA index (10ng ml-1 resistin, 10nmol l-1 g-adiponectin) significantly increased insulin secretion. The RA index was successfully validated in a second human cohort with beta-coefficients of -0.40 (p = 0.006) and -0.38 (p = 0.008) for beta-cell function/ HOMA-IR, and disposition index respectively. Waist-to-hip ratio and RA index were identified as significant modulators of

Protein-losing enteropathy (PLE), characterized by severe hypoalbuminemia and peripheral edema, is a rare manifestation of systemic lupus erythematosus. This present study aimed to identify the distinctive features of lupus-related PLE and evaluate the factors related to the treatment response. From March 1998 to March 2014, the clinical data of 14 patients with lupus PLE and seven patients with idiopathic PLE from a tertiary center were reviewed. PLE was defined as a demonstration of protein leakage from the gastrointestinal tract by either technetium 99m-labelled human albumin scanning or fecal α1-antitrypsin clearance. A positive steroid response was defined as a return of serum albumin to ≥ 3.0 g/dL within 4 weeks after initial steroid monotherapy, and remission as maintenance of serum albumin ≥ 3.0 g/dL for at least 3 months. A high serum total cholesterol level was defined as a level of ≥ 240 mg/dL. The mean age of the lupus-related PLE patients was 37.0 years, and the mean follow-up duration was 55.8 months. Significantly higher erythrocyte sedimentation rate and serum total cholesterol levels were found for lupus PLE than for idiopathic PLE. Among the 14 patients with lupus PLE, eight experienced a positive steroid response, and the serum total cholesterol level was significantly higher in the positive steroid response group. A positive steroid response was associated with an initial high serum total cholesterol level and achievement of remission within 6 months. In lupus-related PLE, a high serum total cholesterol level could be a predictive factor for the initial steroid response, indicating a good response to steroid therapy alone.
This book addresses human and organisational factors which are present at different moments of the lifetime of an at-risk installation (from design to dismantling). At-risk organisations are considered as firstly human systems, and the objective is then to highlight individual and collective mechanisms in these organisations. Several questions are addressed, notably the origins of at-risk behaviour, and the reasons of the repetition of errors by these organisations. A first chapter, while referring to examples, addresses the human dimension of safety: human and organisational factors as obstacles, normal accidents (Three Mile Island), accidents in high-reliability organisations (Chernobyl), identification of root causes (Tokai-mura), and social-technical approach to safety (Fukushima). By also referring to examples, the second chapter addresses how to analyse at-risk organisations: individual behaviours (case of naval and air transport accidents), team coordination (a fire, the Challenger accident), and organisational regulation (organisations forms and routines, explosion of BP Texas City, explosion of Columbia)

The purpose of the paper is to review the utility of the global positioning system (GPS) in the study of health-related physical activity. The paper draws from existing literature to outline the current work performed using GPS to examine transport-related physical activity, with a focus on the relative utility of the approach when combined with geographic information system (GIS) and other data sources including accelerometers. The paper argues that GPS, especially when used in combination with GIS and accelerometery, offers great promise in objectively measuring and studying the relationship of numerous environmental attributes to human behaviour in terms of physical activity and transport-related activity. Limitations to the use of GPS for the purpose of monitoring health-related physical activity are presented, and recommendations for future avenues of research are discussed.

The present study examined competitiveness as a moderator of the relationships between appearance-related factors (i.e., thin-ideal internalization, appearance contingent self-worth) and disordered eating behaviors (i.e., dieting, excessive exercise). Participants were 441 undergraduate females for cross-sectional analyses, with 237 also contributing data longitudinally, 1 year later. Results showed that, in a model including thin-ideal internalization and appearance contingent self-worth and their interactions with competitiveness, thin-ideal internalization (but not appearance contingent self-worth) interacted with competitiveness to identify concurrent levels of both dieting and excessive exercise. Individuals high in both thin-ideal internalization and competitiveness exhibited the highest levels of concurrent dieting and excessive exercise. After controlling for baseline levels of the dependent variables, neither appearance-related factor interacted with competitiveness to predict dieting or excessive exercise. These findings suggest that individuals who are both competitive and accept and strive to achieve the thin ideal may be at risk for disordered eating behaviors. Copyright © 2016 Elsevier Ltd.

The present study aimed to determine the effect of demographic characteristics, occupation, anthropometric indices, and leisure-time physical activity levels on coronary risk and health-related quality of life among military police officers from the State of Santa Catarina, Brazil. The sample included 165 military police officers who fulfilled the study’s inclusion criteria. The International Physical Activity Questionnaire and the Short Form Health Survey were used, in addition to a spreadsheet of socio-demographic, occupational and anthropometric data. Statistical analyses were performed using descriptive analysis followed by Spearman Correlation and multiple linear regression analysis using the backward method. The waist-to-height ratio was identified as a risk factor low health-related quality of life. In addition, the conicity index, fat percentage, years of service in the military police, minutes of work per day and leisure-time physical activity levels were identified as risk factors for coronary disease among police officers. These findings suggest that the Military Police Department should adopt an institutional policy that allows police officers to practice regular physical activity in order to maintain and improve their physical fitness, health, job performance, and quality of life.

Full Text Available Aim: To investigate the quantitative ultrasound measurements and determine the related demographic, clinical and life style parameters. Material and Methods: A questionnaire including demographic features, systemic diseases, physical activity levels and other risk factors for osteoporosis was completed. Measurements of quantitative ultrasound (QUS were performed. Speed of sound (SOS (m/sec measurements were taken at the distal 1/3 radius of the nondominant extremity. Results: Among 2347 persons whom QUS measurements and questionnaires were completed, those aged 35 years and older and that were not taking antiosteoporotic treatment (N= 1867; 1654 women, 213 men were included for the analysis. Mean age of the participants were 52.1±10.7 years and mean SOS scores were 4142.8±185.8 m/sec. The variables that were statistically significant in either independent samples t test or analysis of variance were put in the linear regression analysis. In women, age, years since menopause and duration of lactation were independent predictors for SOS scores (constant= 4367.9 m/sec, age B: -3.8, ß: -0.197, p: 0.01; years since menopause: B: -3.9, ß: -0.211, p: 0.006; duration of lactation B: -0.4, ß: -0.086, p: 0.037. In men, age and level of education affected SOS scores independently (constant= 4271.3 m/sec, age B: -3.8, ß: -0.277, p: 0.001; level of education: B: 18.8, ß: 0.144, p: 0.036. Conclusion: Increasing age is associated with decrements in speed of sound measured by quantitative ultrasound at distal radius. It is important to give education about preventive measures on bone metabolism, especially during the lactation period. (Turkish Journal of Osteoporosis 2011;17:1-5

The aim of the study was to investigate the storage mite sensitivity and related factors in patients with asthma or asthma and rhinitis. 149 patients with asthma or asthma and rhinitis were included to the study. Prick test was performed after addition of Acarus siro (A. siro), Lepidoglyphus destructor (L. destructor), Glycophagus domesticus (G. domesticus) and Tyrophagus putrescentiae (T. putrescentiae) to the standart prick test. Living conditions, smoking history, allergic diseases status, seasonal variations in symptoms were evaluated by a questionnaire. Besides, respiratory screening spesific IgE, L. destructor spesific IgE was examined in a group of patients who were allergic to storage mites according to prick tests. Prick test results showed that; 115 of the patients were sensitized while 34 of them were not. House dust mite sensitivity was detected as mite 58.3%.The storage mite sensitivity for at least one of the studied species was detected in 61.7% of patients. The sensitivity rates were 50.4%, 48.7%, 47%, %40 for A. siro, L. destructor, G. domesticus and T. putrescentiae, respectively. The storage mite sensivity was found higher in the patients from the rural areas (pmite species in %22.7 of the patients who were considered as not sensitized according to the results of the standart prick tests. As a result, storage mites are important allergens in subjects who live in rural areas and close contact with barn, haymow, bin and pantry. Addition of storage mite allergens to the standart prick test panel of patients living in rural area is suitable.
Full Text Available Background: Kidney transplantation is the renal replacement therapy of choice for most patients with end-stage renal disease (ESRD, however, adherence to the recommended lifestyle is critical for a positive prognosis. The purpose of this study was to assess adherence to immunosuppressive therapy and lifestyle recommendations along with some related factors among kidney transplant patients. Materials and Methods: In this descriptive analytical study, all patients completed a questionnaire regarding medication intake and lifestyle recommendations (preventing of infection, self-monitoring, prevention of cardiovascular disease (CVD, and sun protection. The participants were divided into 4 groups according to the level of adherence (good, partial, poor, and nonadherent indicated in their responses. Results: Most kidney recipients were adherent to their drug prescriptions, but were partial, poor, or nonadherent regarding lifestyle recommendations. Increased passage of time since transplantation and low family support and educational level resulted in nonadherence. Men showed greater adherence to medication intake than women. Patients with lower number of drugs and reported drug side-effects illustrated better adherence to medication intake. Women adhered to infection protection recommendations more than men, and older and married patients adhered to cardiovascular prevention recommendations more than others. However, younger patients showed greater adherence to self-monitoring recommendations, and singles, young individuals, and women were adherent to sun protection recommendations. Conclusions: Nonadherence is common among kidney transplant recipients. Thus, it is necessary to determine patients who are at risk of nonadherence and to introduce more educational programs to improve their adherence and their quality of life (QOL.

Full Text Available ABSTRACT Cervical cancer is one of most common diseases among women worldwide. Human papilloma virus (HPV is known as precursor of cervical cancer. Cervical cancer can be prevented effectively by practicing hpv vaccine. But the coverage of HPV vaccine is remain low. The objection of study was to analyze factors related to HPV vaccine pratice among adult women. This study used case control design with sample size 25 for each group. Sample case was women who took HPV vaccine in IBI Kota Kediri on 2013, while sample control was neighboor from the sample case who didn’t take HPV vaccine. The independent variabels were age, education level, marital status, income level, knowledge, family support, family history of cervical cancer and the dependent variable was HPV vaccine practice. Those variables was analyzed with chi square or Fisher’s exact with significancy level at 95%. The result showed that there were correlation between education level (p = 0.006; c = 0.346, knowledge (p = 0.001; c = 0.464, and family support (p = 0.000; c = 0.516 with HPV vaccination practice. While there were no correlation between age (p = 0.275, marital status (0.490 and income level (p = 0.098 and family history of cervical cancer (p = 1.000 with HPV vaccination practice. Based on data from this study can be concluded that family support and knowledge had average strenght correlation withHPV vaccine practice among adult women. So, the intervention should be focused in increasing knowledge among women and their family about the important of HPV vaccine as a cervical cancer prevention. Keywords: practice, preventive, HPV, vaccine, adult women

Recognition of the complexity of asthma management has led to the development of asthma treatment guidelines that include the recommendation that all pediatric asthma patients receive a written asthma action plan. We assessed the readability, suitability, and characteristics of asthma action plans, elements that contribute to the effectiveness of action plan use, particularly for those with limited literacy. This was a descriptive study of 30 asthma action plans (27 state Department of Health (DOH)-endorsed, 3 national action plans endorsed by 6 states). (1) readability (as assessed by Flesch Reading Ease, Flesch-Kincaid, Gunning Fog, Simple Measure of Gobbledygook, Forcast), (2) suitability (Suitability Assessment of Materials [SAM], adequate: ≥ 0.4; unsuitable: typography (30.0%), learning stimulation/motivation (26.7%), and graphics (13.3%). There were no statistically significant differences between the average grade level or SAM score of state DOH developed action plans and those from or adapted from national organizations. Plans varied with respect to terms used, symptoms included, and recommended actions. Specific improvements in asthma action plans could maximize patient and parent understanding of appropriate asthma management and could particularly benefit individuals with limited literacy skills.

Background. Research shows that high-functioning teams improve patient outcomes in primary care. However, there is no consensus on a conceptual model of team-based primary care that can be used to guide measurement and performance evaluation of teams. Objective. To qualitatively understand whether the Systems Engineering Initiative for Patient Safety (SEIPS) model could serve as a framework for creating and evaluating team-based primary care. Methods. We evaluated qualitative interview data from 19 clinicians and staff members from 6 primary care clinics associated with a large Midwestern university. All health care clinicians and staff in the study clinics completed a survey of their communication connections to team members. Social network analysis identified key informants for interviews by selecting the respondents with the highest frequency of communication ties as reported by their teammates. Semi-structured interviews focused on communication patterns, team climate and teamwork. Results. Themes derived from the interviews lent support to the SEIPS model components, such as the work system (Team, Tools and Technology, Physical Environment, Tasks and Organization), team processes and team outcomes. Conclusions. Our qualitative data support the SEIPS model as a promising conceptual framework for creating and evaluating primary care teams. Future studies of team-based care may benefit from using the SEIPS model to shift clinical practice to high functioning team-based primary care. PMID:27578837

Mobile devices addiction has been an important research topic in cognitive science, mental health, and human-machine interaction. Previous works observed mobile device addiction by logging mobile devices activity. Although immersion has been linked as a significant predictor of video game addiction, investigation on addiction factors of mobile device with behavioral measurement has never been done before. In this research, we demonstrated the usage of eye tracking to observe effect of screen size on experience of immersion. We compared subjective judgment with eye movements analysis. Non-parametric analysis on immersion score shows that screen size affects experience of immersion (pmobile devices addiction. Our experimental results are also useful to develop a guideline as well as intervention strategy to deal with smartphone addiction.

The present contribution reviews evidence that supports the relevance of childhood antecedents of personality disorders, and advocates that the validity of a Five-Factor Model framework for describing general trait differences in childhood can be extended towards the field of developmental personality difficulties. In addition, we suggest that several traditional childhood Axis I conditions include a substantial trait component that may be responsible for the recurring finding that childhood Axis I disorders are predictive for adult Axis II disorders. Given the valuable information provided by a trait assessment, we further propose to integrate dimensional personality and personality pathology measures as standard tools in mental health assessments at a young age. © 2012 The Authors.

In niobium superconducting radio frequency (SRF) cavities for particle acceleration, a decrease of the quality factor at lower fields—a so-called low field Q slope or LFQS—has been a long-standing unexplained effect. By extending the high Q measurement techniques to ultralow fields, we discover two previously unknown features of the effect: (i) saturation at rf fields lower than Eacc˜0.1 MV /m ; (ii) strong degradation enhancement by growing thicker niobium pentoxide. Our findings suggest that the LFQS may be caused by the two level systems in the natural niobium oxide on the inner cavity surface, thereby identifying a new source of residual resistance and providing guidance for potential nonaccelerator low-field applications of SRF cavities.

We have reported earlier some new results related to the seasonal and solar cycle changes in the north-south component of IMF (Bz) observed near 1 A.U. A relationship between geomagnetic activity and non-radial solar wind flows were reported recently. In this connection, we are planning some studies for IHY 2007. We propose to identify non-radial flow structures in the interplanetary medium using IPS observations and predict the associated IMF Bz structures. The effect of geomagnetic storms near magnetic equator associated with non-radial solar wind flows will be studied using magnetometer observations in Trivandrum.

Nuclear factor E2-related factor 2 (Nrf2) is a transcription factor known to induce the expression of a variety of antioxidant and detoxification genes. Recently, increasing evidence has revealed roles for Nrf2 in glucose, lipid, and energy metabolism; however, the exact functions of Nrf2 in hepatocyte biology are largely unclear. In the current study, the transient knockdown of Nrf2 via siRNA transfection enhanced the glucose uptake of fasting AML12 hepatocytes to 325.3 ± 11.1% ( P glucose metabolism were then examined in AML12 cells under both high-glucose (33 mmol/L) and low-glucose (4.5 mmol/L) conditions. NK lowered the gene and protein expression of the anti-oxidases heme oxygenase-1 and NAD(P)H: quinone oxidoreductase 1 and increased p-eukaryotic initiation factor-2α S51 , p-nuclear factor-κB p65 S276 , and its downstream proinflammatory factors, including interleukin-1 beta, tumor necrosis factor-α, matrix metalloproteinase 2, and matrix metalloproteinase 9, at the protein level. NK also altered the protein expression of fibroblast growth factor 21, glucose transporter type 4, insulin-like growth factor 1, forkhead box protein O1, p-AKT S473 , and p-GSK3α/β Y279/Y216 , which are involved in glucose uptake, glycogenesis, and gluconeogenesis in AML12 cells. Our results provide a comprehensive understanding of the central role of Nrf2 in the regulation of glucose metabolism in AML12 hepatocytes, in addition to its classical roles in the regulation of redox signaling, endoplasmic reticulum stress and proinflammatory responses, and support the potential of Nrf2 as a therapeutic target for the prevention and treatment of obesity and other associated metabolic syndromes. Impact statement Increasing evidence supports the complexity of Nrf2 functions beyond the antioxidant and detoxification response. Previous in vivo studies employing either Nrf2-knockout or Nrf2-activated mice have achieved a similar endpoint: protection against an obese and

Recent work has demonstrated that math anxiety is more than just the product of poor math skills. Psychosocial factors may play a key role in understanding what it means to be math anxious, and hence may aid in attempts to sever the link between math anxiety and poor math performance. One such factor may be the extent to which individuals integrate math into their sense of self. We adapted a well-established measure of this degree of integration (i.e., self-other overlap) to assess individual...

Urban and peri-urban forests are recognized as basic elements for Nature-Based Solutions (NBS), as they preserve and may increase environmental quality in urbanized contexts. For this reason, the amount of forest land per inhabitant is a pivotal efficiency indicator to be considered in the sustainable governance, land management, planning and design of metropolitan areas. The present study illustrates a multivariate analysis of per-capita forest area (PFA) in mainland Attica, the urban region surrounding Athens, Greece. Attica is considered a typical case of Mediterranean urbanization where planning has not regulated urban expansion and successive waves of spontaneous growth have occurred over time. In such a context, an analysis of factors that can affect landscape changes in terms of PFA may inform effective strategies for the sustainable management of socio-ecological local systems in light of the NBS perspective. A total of 26 indicators were collected per decade at the municipal scale in the study area with the aim to identify the factors most closely associated to the amount of PFA. Indicators of urban morphology and functions have been considered together with environmental and topographical variables. In Attica, PFA showed a progressive decrease between 1960 and 2010. In particular, PFA progressively declined (1980, 1990) along fringe areas surrounding Athens and in peri-urban districts experiencing dispersed expansion of residential settlements. Distance from core cities and from the seacoast, typical urban functions (e.g., multiple use of buildings and per capita built-up area) and percentage of agricultural land-use in each municipality are the variables most associated with high PFA. In recent years, some municipalities have shown an expansion of forest cover, mainly due to land abandonment and forest recolonization. Findings from this case study have allowed us to identify priorities for NBS at metropolitan level aimed at promoting more sustainable

Social media, such as Twitter, have become major channels of communication and commentary on popular culture, including conversations on our nation's leading addiction: tobacco. The current study examined Twitter conversations following two tobacco-related events in the media: (1) President Obama's doctor announcing that he had quit smoking and (2) the release of a photograph of Miley Cyrus (a former Disney child star) smoking a cigarette. With a focus on high-profile individuals whose actions can draw public attention, we aimed to characterise tobacco-related conversations as an example of tobacco-related public discourse and to present a novel methodology for studying social media. Tweets were collected 11-13 November 2011 (President Obama) and 1-3 August 2011 (Miley Cyrus) and analysed for relative frequency of terms, a novel application of a linguistic methodology. The President Obama data set (N=2749 tweets) had conversations about him quitting tobacco as well as a preponderance of information on political activity, links to websites, racialised terms and mention of marijuana. Websites and terms about Obama's smoke-free status were most central to the conversation. In the Miley Cyrus data (N=4746 tweets), terms that occurred with the greatest relative frequency were positive, emotional and supportive of quitting (eg, love, and please), with words such as 'love' most central to the conversation. People are talking about tobacco-related issues on Twitter, and semantic network analysis can be used to characterise on-line conversations. Future interventions may be able to harness social media and major current events to raise awareness of smoking-related issues. Published by the BMJ Publishing Group Limited.

The goal of this study was to examine the perceived usefulness, the perceived ease of use and the perceived behavioral control of a Hospital Information System (HIS) for the care staff. We administrated a questionnaire composed of open-end and closed questions, based on the main concepts of Technology Acceptance Model. As results, the perceived usefulness, ease of use and behavioral control (self-efficacy and organizational support) are correlated with medical occupations. As an example, we found that a half of the medical secretaries consider the HIS is ease of use, at the opposite to the anesthesiologists, surgeons and physicians. Medical secretaries reported also the highest rate of PBC and a high rate of PU. Pharmacists reported the highest rate of PU but a low rate of PBC, which is similar to the rate of the surgeons and physicians. Content analysis of open questions highlights factors influencing these constructs: ergonomics, errors in the documenting process, insufficient compatibility with the medical department or the occupational group. Consequently, we suggest that the gap between the perceptions of the different occupational groups may be explained by the use of different modules and by interdependency of the care stare staff.

Although researchers argue for the importance of involving the public in developing health policy, there has been little focus on central research questions - such as what techniques of public participation work, in what circumstances, and why. This paper presents a realist synthesis which identifies and explains the underlying mechanisms and specific contextual factors that lead to effective public participation in health policy and planning. Peer-reviewed, English language literature was searched, which resulted in 77 articles for review and synthesis. This synthesis uncovered the underlying mechanism of 'political commitment' that generates public participation effectiveness. The other three possible underlying mechanisms, namely: 'partnership synergy', 'inclusiveness' and 'deliberativeness', were found to potentially provide further explanation on public participation effectiveness for health policy and planning. The findings of this review provide evidence that can be useful to health practitioners and decision-makers to actively involve the public when drafting public health policies and programs and, more importantly, guide them in deciding which strategies to best employ for which contexts.

Most patients with acute pericarditis have a benign course and a good prognosis. However, a minority of patients develop complicated pericarditis, and the care of these patients is the focus of this review. Specifically, we address risk factors, multimodality imaging, pathophysiology, and novel treatments. The authors conclude that: 1) early high-dose corticosteroids, a lack of colchicine, and an elevated high-sensitivity C-reactive protein are associated with the development of complicated pericarditis; 2) in select cases, cardiovascular magnetic resonance imaging may aid in the assessment of pericardial inflammation and constriction; 3) given phenotypic similarities between recurrent idiopathic pericarditis and periodic fever syndromes, disorders of the inflammasome may contribute to relapsing attacks; and 4) therapies that target the inflammasome may lead to more durable remission and resolution. Finally, regarding future investigations, the authors discuss the potential of cardiovascular magnetic resonance to inform treatment duration and the need to compare steroid-sparing treatments to pericardiectomy.

Full Text Available Abstract Background The prisoner population is characterised by a high burden of disease and social disadvantage, and ex-prisoners are at increased risk of death following release. Much of the excess mortality can be attributed to an increased risk of unnatural death, particularly from drug overdose; however, relatively few studies have investigated the circumstances surrounding drug-related deaths among released prisoners. This study aimed to explore and compare the circumstances of death for those who died from accidental drug-related causes to those who died from all other reportable causes. Methods A nationwide search of the Australian National Coroners Information System (NCIS was conducted to identify reportable deaths among ex-prisoners from 2000 to 2007. Using a structured coding form, NCIS records for these cases were interrogated to explore causes and circumstances of death. Results Coronial records for 388 deceased ex-prisoners were identified. Almost half of these deaths were a result of accidental drug-related causes (45%. The majority of accidental drug-related deaths occurred in a home environment, and poly-substance use at or around the time of death was common, recorded in 72% of drug-related deaths. Ex-prisoners who died of accidental drug-related causes were on average younger and less likely to be Indigenous, born in Australia, married, or living alone at or around the time of death, compared with those who died from all other reportable causes. Evidence of mental illness or self-harm was less common among accidental drug-related deaths, whereas evidence of previous drug overdose, injecting drug use, history of heroin use and history of drug withdrawal in the previous six months were more common. Conclusions Drug-related deaths are common among ex-prisoners and often occur in a home (vs. public setting. They are often associated with use of multiple substances at or around the time of death, risky drug-use patterns, and even

Relational aggression is a form of covert or indirect aggression or bullying in which harm is caused through damage to relationships or social status within a group, rather than through physical violence. We compare findings from empirical research into relational aggression with the depictions, interpretations and interventions described in trade-books and popular media dealing with that same topic. Relational aggression is more common and more studied among girls than boys and is popularly described as synonymous with "mean-girl" behaviors. We investigate the degree that popular trade books and movies accurately portray findings from researched investigations including the incidence and indicators of the condition and its remedies. We determine that there is a great deal of similarity between these two sources in how relational aggression is understood and how it may be treated. The concurrence across both dissemination formats reflects terminology and definitions, the harmful effects of relational aggression, the gender-specific nature of the condition to women and girls, its age of occurrence, the impact of parenting styles, its relationship to girls' social competence, and nature of its expression through non-physical means.

There is a lack of information on health-related quality of life (HRQOL) for Aboriginal diabetic people. To investigate HRQOL among aboriginal diabetics living in an isolated, rural Canadian community. Mixed methods: (1) A mailed health-related survey; and (2) a population based retrospective chart review. People aged 17 years and older living in the Bella Coola Valley, British Columbia, Canada, and having a chart at the Bella Coola Medical Clinic as of September 2001 were asked to complete a detailed HRQOL survey during the period August to December 2001. Demographics (age, sex, ethnicity). Health-related quality of life was measured using the MOS 36-item Short Form Health Survey (SF-36), and the US Centers for Disease Control healthy day's items. Relatively greater percentages of diabetic people (n = 72 [57%]) completed the survey than did non-diabetics (n = 675 [37%]). Mean scores for Aboriginal people were lower/poorer than mean scores for non-Aboriginal people in all the quality of life questions. Mean scores for diabetic people were lower than mean scores for non-diabetics in all the quality of life questions. Aboriginal diabetics reported the worst scores on almost all of our quality of life questions. Rural diabetics experience significant impairment in their health-related quality of life. Among rural diabetics, Aboriginals report the worst HRQOL scores. Compared with other people, Aboriginals fare worse in HRQOL, which may explain the difference.

Methods for evaluating the impact of fires within tropical forests are needed as fires become more frequent and human populations and demands on forests increase. Short- and long-term fire effects on soils are determined by the prefire, fire, and postfire environments. We placed these components within a fire-disturbance continuum to guide our literature synthesis and develop an integrated soil burn severity index. The soil burn severity index provides a set of indicators that reflect the range of conditions present after a fire. The index consists of seven levels, an unburned level and six other levels that describe a range of postfire soil conditions. We view this index as a tool for understanding the effects of fires on the forest floor, with the realization that as new information is gained, the index may be modified as warranted. ??

A gap exists between evidence-based medicine and clinical-practice. Every day, healthcare professionals (HCPs) combine empirical evidence and subjective experience in order to maximize the effectiveness of interventions. Consequently, it is important to understand how HCPs interpret the research evidence and apply it in everyday practice. We focused on the prevention of falls, a common cause of injury-related morbidity and mortality in later life, for which there is a wide range of known risk factors. To use the Analytic Hierarchy Process (AHP) to investigate the opinions of HCPs in prioritizing risk factors for preventing falls. We used the AHP to develop a hierarchy of risk factors for falls based on the knowledge and experience of experts. We submitted electronic questionnaires via the web, in order to reach a wider number of respondents. With a web service, we pooled the results and weighted the coherence and the experience of respondents. Overall, 232 respondents participated in the study: 32 in the technical pilot study, nine in the scientific pilot study and 191 respondents in the main study. We identified a hierarchy of 35 risk factors, organized in two categories and six sub-categories. The hierarchy of risk factors provides further insights into clinicians' perceptions of risk factors for falls. This hierarchy helps understand the relative importance that clinicians place on risk factors for falls in older people and why evidence-based guidelines are not always followed. This information may be helpful in improving intervention programs and in understanding how clinicians prioritize multiple risk factors in individual patients. The AHP method allows the opinions of HCPs to be investigated, giving appropriate weight to their coherence, background and experience.

Research on racial prejudice is currently characterized by the existence of diverse concepts (e.g., implicit prejudice, old-fashioned racism, modern racism, aversive racism) that are not well integrated from a general perspective. The present article proposes an integrative framework for these concepts employing a cognitive consistency perspective. Specifically, it is argued that the reliance on immediate affective reactions toward racial minority groups in evaluative judgments about these groups depends on the consistency of this evaluation with other relevant beliefs pertaining to central components of old-fashioned, modern, and aversive forms of prejudice. A central prediction of the proposed framework is that the relation between "implicit" and "explicit" prejudice should be moderated by the interaction of egalitarianism-related, nonprejudicial goals and perceptions of discrimination. This prediction was confirmed in a series of three studies. Implications for research on prejudice are discussed.

Recent decades have witnessed a surge in international programmes established to assist the adoption of renewable energy technologies (RETs) in low and lower-middle income countries. So far, such programmes have yielded mixed success. While partnerships between international, national and local organisations have become the pre-eminent model for RET programmes, we know relatively little about their contribution. This article traces the role of renewable energy partnerships in development cooperation, shifting the analytical emphasis from barriers and drivers to key actors and their relationships. It presents a relational approach for the analysis of development assistance for renewable energy, drawing on theories concerning the role of strong and weak ties in inter-organisational networks. Through an analysis of seven empirical cases from Central America, the article provides insights into how different forms of inter-organisational relationships can facilitate implementation of RET programmes but do not necessarily enhance the capacities of local organisations in a way to support a more sustainable adoption of RETs. On the basis of this analysis, theoretical and policy implications are given concerning the potential of relational approaches for researching technology diffusion processes, and the role of strong and weak ties for the success – or failure – of renewable energy partnerships. - Highlights: • Study of renewable energy partnerships in development cooperation. • Relational framework for analysis of inter-organisational technology diffusion. • Empirical cases of renewable energy partnerships in Central America. • Different types of network relationships enable/inhibit sustainable adoption. • Three policy recommendations for programme development

Statistics indicate a high risk of developing work-related musculoskeletal disorders among hospital nurses. The challenge is to understand the associations between musculoskeletal symptoms and various individual and occupational risk factors. This study examined the direct and indirect interactions of various risk factors with musculoskeletal complaints in hospital nurses. In a cross-sectional design, Iranian hospital nurses from Semnan University of Medical Sciences participated in a questionnaire survey reporting their perceived perceptions of various work-related risk factors and musculoskeletal symptoms. We tested our proposed structural equation model to evaluate the relations between latent and observed concepts and the relative importance and strength of exogenous variables in explaining endogenous musculoskeletal complaints. Measurement model fits the data relatively acceptable. Our findings showed direct effects of psychological, role-related and work posture stressors on musculoskeletal complaints. Fatigue mediated the adverse indirect relations of psychological, role-related, work posture and individual factors with musculoskeletal complaints. Structural equation modeling may provide methodological opportunities in occupational health research with a potential to explain the complexity of interactions among risk factors. Prevention of work-related musculoskeletal disorders among nurses must account for physical and psychosocial conditions.

Full Text Available Orientation: A growing movement of foreign nationals is settling in South Africa. Given this, there is a need to understand not only those factors influencing foreign nationals to settle in South Africa but also their lived experiences as a basis for individual career development. Research purpose: To investigate the expatriation motivational factors and experiences of selfinitiated academic expatriates in South Africa. Motivation for the study: Calls have been made within the careers literature for more empirical focus on understanding career development using some of the neglected sample groups. Research approach, design and method: The interpretive paradigm was adopted to understand the main purpose of the study. Guided by study objectives, unstructured interviews were conducted using a sample of foreign academics working in South Africa (n = 25. Main findings: Individual stories and narratives highlighted that academics relocated for the following reasons: (1 individual preference, (2 economic meltdown and (3 political conditions. Furthermore, the lived experiences of the expatriates reflected discrimination within the workplace and the community of residences in South Africa. Practical and managerial implications: Research findings indicate that the human resources (HR function can come up with interventions that positively influence the lived experience and career development of foreign academics working in South Africa. Contribution: The expatriate experience framed in this study provides a picture of the career development processes of neglected sample groups in the extant literature. Such an understanding is key in advancing literature and proposing interventions. All this is important given the global trend on labour and skills movement added to the role South Africa plays in the international arena.

Pregnancy rates are substantially higher among homeless youth than in the general population of youth, yet little is known about homeless adolescents' and young adults' pregnancy-related attitudes and behaviors. Pregnancy-related attitudes and behaviors were examined among two samples of sexually active homeless 13-24-year-olds in Los Angeles County. Data from 37 semistructured interviews conducted in March-April 2011 were analyzed using standard qualitative methods. Data from a structured survey with 277 respondents, conducted between October 2008 and August 2009, were analyzed primarily using regression modeling. More than half of interview respondents held ambivalent attitudes toward pregnancy, and ambivalent youth reported less contraceptive use than others. The interviews identified several potential influences on pregnancy attitudes: barriers associated with homelessness, readiness to settle down, desire to achieve goals, belief that a child would create something positive in life, and family and partners. In the survey, having positive attitudes toward pregnancy was positively associated with duration of homelessness (odds ratio, 1.6), contact with relatives (1.1) and relationship commitment (1.8); it was negatively associated with frequency of drinking (0.9). Relationship commitment was positively associated with nonuse of an effective contraceptive method at last sex (1.5). Effective and accessible pregnancy prevention and family planning programs for homeless youth are needed. Youths' ambivalence toward pregnancy and feelings of relationship commitment warrant attention as possible areas for programs to address. Copyright © 2012 by the Guttmacher Institute.

Evidence shows that violations of the United States (US) child labor regulations are common. The main purpose of this study was to investigate the magnitude and nature of work-related deaths among youth involving violations of US child labor regulations. We analyzed Census of Fatal Occupational Injury data from 2001 to 2012 using descriptive statistics and Chi-square tests. Between 2001 and 2012, 406 workers under age 18 were recorded in the CFOI as having suffered a fatal work-related injury. Among these cases, 233 were covered by the US child labor regulations. Forty-three percent of these cases involved at least one violation. The majority of cases that were not covered by the regulations involved decedents working on their family's farms (N = 139). Violations of federal child labor regulations are a significant contributor to work-related deaths among youth in the United States. Increased investment in enforcement is needed to prevent further young worker deaths involving child labor violations. Am. J. Ind.

Our purpose was to investigate longitudinally health-related quality of life (HRQOL) outcomes and related factors up to 2 years post-pediatric SCT. A total of 99 mothers of patients, aged 1.5-17 years, completed two standardized HRQOL questionnaires, generic and disease specific (DS), about the child, and reported on their own symptoms of depression and family function pre-SCT, 12 and 24 months post-SCT. Clinical (diagnosis, radiation), child (age) and family (maternal depression) information was also obtained. Significant improvement in physical and psychosocial HRQOL from pre-SCT to 1 or 2 years post-SCT was reported. Survivors of ALL were reported to have poorer physical and psychosocial HRQOL than survivors of solid tumors on the DS measure. Maternal depression was negatively associated with physical and psychosocial HRQOL. Maternal education (higher) at pre-SCT predicted improvements in physical domains 2 years post-SCT; mother's age (older) and child's age (younger) also predicted improvements of physical and emotional HRQOL. We conclude that survivors of pediatric SCT improved physical and psychosocial HRQOL by 1 and 2 years post-SCT. Older survivors whose mothers are younger and distressed, with lower education at SCT have compromised HRQOL compared to other survivors. This study has important implications for the care of SCT survivors and their families.

Latent variable modeling methods have demonstrated utility for understanding the structure of executive control (EC) across development. These methods are utilized to better characterize the relation between EC and mathematics achievement in the preschool period, and to understand contributing sources of individual variation. Using the sample and battery of laboratory tasks described in Wiebe, Espy and Charak (2008), latent EC was related strongly to emergent mathematics achievement in preschool, and was robust after controlling for crystallized intellectual skills. The relation between crystallized skills and emergent mathematics differed between girls and boys, although the predictive association between EC and mathematics did not. Two dimensions of the child 's social environment contributed to mathematics achievement: social network support through its relation to EC and environmental stressors through its relation with crystallized skills. These findings underscore the need to examine the dimensions, mechanisms, and individual pathways that influence the development of early competence in basic cognitive processes that underpin early academic achievement. © 2010 Blackwell Publishing Ltd.

The universe of study was made up of 939 children aged 9, 12 and 15 years, from whom 120 were taken as equivalent random sample (63 females and 57 males. The risk characterization was based on deforming oral habits (40%, muscular hypotonia (16,70%, heredity performance (32,5%, malnutrition (20%, dental caries (56,70% and lost teeth (25%. The estimated odds ratio was more related to oral habits (7,69% muscular hypotonia (12,43% and heredity (3,90%, which means that there exists the probability of getting sick in the face of the considered risk factors. This allows setting up an epidemiological surveillance system on this issue.

Visual working memory (VWM) capacity is reduced in older adults. Research has shown age-related impairments to VWM encoding, but aging is likely to affect multiple stages of VWM. In the present study, we recorded the event-related potentials (ERPs) of younger and older adults during VWM maintenance and retrieval. We measured encoding-stage processing with the P1 component, maintenance-stage processing with the contralateral delay activity (CDA), and retrieval-stage processing by comparing the activity for old and new items (old-new effect). Older adults showed lower behavioral capacity estimates (K) than did younger adults, but surprisingly, their P1 components and CDAs were comparable to those of younger adults. This remarkable dissociation between neural activity and behavior in the older adults indicated that the P1 and CDA did not accurately assess their VWM capacity. However, the neural activity evoked during VWM retrieval yielded results that helped clarify the age-related differences. During retrieval, younger adults showed early old-new effects in frontal and occipital areas and a late central-parietal old-new effect, whereas older adults showed a late right-lateralized parietal old-new effect. The younger adults' early old-new effects strongly resembled an index of perceptual fluency, suggesting that perceptual implicit memory was activated. The activation of implicit memory could have facilitated the younger adults' behavior, and the lack of these early effects in older adults may suggest that they have much lower-resolution memory than do younger adults. From these data, we speculated that younger and older adults store the same number of items in VWM, but that younger adults store a higher-resolution representation than do older adults.

A method is developed to estimate the potential energy diagram for a full catalytic reaction for a range of late transition metals on the basis of a calculation (or an experimental determination) for a single metal. The method, which employs scaling relations between adsorption energies, is illustrated by calculating the potential energy diagram for the methanation reaction and ammonia synthesis for 11 different metals on the basis of results calculated for Ru. It is also shown that considering the free energy diagram for the reactions, under typical industrial conditions, provides additional insight into reactivity trends

The hepatocyte, the main cellular component of the liver, exhibits variable susceptibility to different types of injury induced by endogenous or exogenous factors. Hepatocellular dysfunction or death and regeneration are dependent upon the complicated interactions between numerous biologically active molecules. Platelet-activating factor (PAF) seems to play a pivotal role as the key mediator of liver injury in the clinical and experimental setting, as implied by the beneficial effects of its receptor antagonists. A comprehensive up-to-date overview of the specific functional and regulatory properties of PAF in conditions associated with liver injury is attempted in this review. PMID:16773686

Emerging studies indicate that several species such as corvids, apes and children solve 'The Crow and the Pitcher' task (from Aesop's Fables) in diverse conditions. Hidden beneath this fascinating paradigm is a fundamental question: by cumulatively interacting with different objects, how can an agent abstract the underlying cause-effect relations to predict and creatively exploit potential affordances of novel objects in the context of sought goals? Re-enacting this Aesop's Fable task on a humanoid within an open-ended 'learning-prediction-abstraction' loop, we address this problem and (i) present a brain-guided neural framework that emulates rapid one-shot encoding of ongoing experiences into a long-term memory and (ii) propose four task-agnostic learning rules (elimination, growth, uncertainty and status quo) that correlate predictions from remembered past experiences with the unfolding present situation to gradually abstract the underlying causal relations. Driven by the proposed architecture, the ensuing robot behaviours illustrated causal learning and anticipation similar to natural agents. Results further demonstrate that by cumulatively interacting with few objects, the predictions of the robot in case of novel objects converge close to the physical law, i.e. the Archimedes principle: this being independent of both the objects explored during learning and the order of their cumulative exploration. © 2016 The Author(s).
Full Text Available Correct reproductive timing is crucial for fitness. Breeding phenology even in similar species can differ due to different selective pressures on the timing of reproduction. These selection pressures define species' responses to warming springs. The temporal match-mismatch hypothesis suggests that timing of breeding in animals is selected to match with food availability (synchrony. Alternatively, time-dependent breeding success (the date hypothesis can result from other seasonally deteriorating ecological conditions such as intra- or interspecific competition or predation. We studied the effects of two ultimate factors on the timing of breeding, synchrony and other time-dependent factors (time-dependence, in sympatric populations of two related forest-dwelling passerine species, the great tit (Parus major and the willow tit (Poecile montanus by modelling recruitment with long-term capture-recapture data. We hypothesized that these two factors have different relevance for fitness in these species. We found that local recruitment in both species showed quadratic relationships with both time-dependence and synchrony. However, the importance of these factors was markedly different between the studied species. Caterpillar food played a predominant role in predicting the timing of breeding of the great tit. In contrast, for the willow tit time-dependence modelled as timing in relation to conspecifics was more important for local recruitment than synchrony. High caterpillar biomass experienced during the pre- and post-fledging periods increased local recruitment of both species. These contrasting results confirm that these species experience different selective pressures upon the timing of breeding, and hence responses to climate change may differ. Detailed information about life-history strategies is required to understand the effects of climate change, even in closely related taxa. The temporal match-mismatch hypothesis should be extended to consider

Elucidating the confounding influence of multiple environmental factors on benthic diatom communities is important in developing water quality predictive models for better guidance of stream management efforts. The objective of this study was to explore the relative impact of metal pollution and hydromorphological alterations in, addition to nutrient enrichment and organic pollution, on diatom taxonomic composition with the view to improve stream diatom-based water quality inference models. Samples were collected twice at 20 sampling stations in the tropical Manyame Catchment, Zimbabwe. Diatom, macroinvertebrate communities and environmental factors were sampled and analysed. The variations in diatom community composition explained by different categories of environmental factors were analysed using canonical correspondence analysis using variance partitioning (partial CCA). The following variations were explained by the different predictor matrices: nutrient levels and organic pollution - 10.4%, metal pollution - 8.3% and hydromorphological factors - 7.9%. Thus, factors other than nutrient levels and organic pollution explain additional significant variation in these diatom communities. Development of diatom-based stream water quality inference models that incorporate metal pollution and hydromorphological alterations, where these are key issues, is thus deemed necessary. - Highlights: • Confounding influences of multiple environmental factors on diatom communities are elucidated. • Variation explained: nutrients + organic pollution - 10.4%, metals - 8.3% and hydromorphological factors - 7.9%. • Calibration of existing or development of new indices may be necessary.
Full Text Available High-risk human papillomaviruses (hrHPV are responsible for anogenital and oropharyngeal cancers, which together account for at least 5% of cancers worldwide. Industrialised nations have benefitted from highly effective screening for the prevention of cervical cancer in recent decades, yet this vital intervention remains inaccessible to millions of women in low- and middle-income countries (LMICs, who bear the greatest burden of HPV disease. While there is an urgent need to increase investment in basic health infrastructure and rollout of prophylactic vaccination, there are now unprecedented opportunities to exploit recent scientific and technological advances in screening and treatment of pre-invasive hrHPV lesions and to adapt them for delivery at scale in resource-limited settings. In addition, non-surgical approaches to the treatment of cervical intraepithelial neoplasia and other hrHPV lesions are showing encouraging results in clinical trials of therapeutic vaccines and antiviral agents. Finally, the use of next-generation sequencing to characterise the vaginal microbial environment is beginning to shed light on host factors that may influence the natural history of HPV infections. In this article, we focus on recent advances in these areas and discuss their potential for impact on HPV disease.

Adverse pregnancy outcomes entail a large health burden for the mother and offspring; a part of it might be avoided by better understanding the role of environmental factors in their etiology. Our aims were to review the assessment tools to characterize fecundity troubles and pregnancy-related outcomes in human populations and their sensitivity to environmental factors. For each outcome, we reviewed the possible study designs, main sources of bias, and their suggested cures. In terms of study design, for most pregnancy outcomes, cohorts with recruitment early during or even before pregnancy allow efficient characterization of pregnancy-related events, time-varying confounders, and in utero exposures that may impact birth outcomes and child health. Studies on congenital anomalies require specific designs, assessment of anomalies in medical pregnancy terminations, and, for congenital anomalies diagnosed postnatally, follow-up during several months after birth. Statistical analyses should take into account environmental exposures during the relevant time windows; survival models are an appropriate approach for fecundity, fetal loss, and gestational duration/preterm delivery. Analysis of gestational duration could distinguish pregnancies according to delivery induction (and possibly pregnancy-related conditions). In conclusion, careful design and analysis are required to better characterize environmental effects on human reproduction. PMID:24363355

Full Text Available Abstract Background Melanoma incidence in the UK has doubled over two decades, yet there is conflicting evidence about factors which prompt or delay patients seeking advice. Aim: To explore patient understanding of pigmented skin lesions (moles and skin cancer, and factors which influence seeking help in primary care. Method Semi-structured interviews with forty MoleMate Trial participants, analysed using the theoretical framework of the Safer-Andersen model of Total Patient Delay. Results Patient understanding and awareness was influenced by personal, family and friends' experiences of moles, skin cancer and other cancers, knowledge of risk factors, and the lay media. The route to consulting was complex and often iterative. For lesions that people could see, detecting and appraising change was influenced by comparisons with a normal mole on themselves, a family member, friend or image. Inferring illness came about with recognition of changes (particularly size as serious, and associated 'internal' symptoms such as pain. For lesions that people could not see, family, friends and health professionals detected and appraised changes. Deciding to seek help was often prompted by another person or triggered by rapid or multiple changes in a mole. Three of four people subsequently diagnosed with melanoma did not seek help; instead, their GP opportunistically noticed the lesion. Conclusions Changing moles are often perceived as trivial and not signifying possible skin cancer. This study contributes to current national strategies to improve patient awareness and earlier diagnosis of cancer by highlighting factors that can trigger or act as barriers to seeking help.

Full Text Available Background: Despite the positive impact of cardiac rehabilitation (CR on quality of life and mortality, the majority of people who could benefit from this program fail to participate in it. The lack of referral from the physician is a common reason that patients give for not seeking CR. The objective of this study was to compare factors affecting CR referral by cardiologists. Methods: A cross-sectional survey of 122 cardiologists, including 89 general cardiac specialists and 33 fellows in cardiology from 11 major cardiology training centers in Iran, was done in 2010. They responded to the 14- item investigator-generated survey, examining the physician’s attitudinal and knowledge factors affecting CR referral. Results: 47.9% of the subjects reported having available CR centers but only 6.6% reported continuous medical education on the topic. 90.7% of the physicians reported that less than 15% of patients are referred to CR centers. The main factor affecting the low referral rate was limited general knowledge about CR programs (79.5% such as program attributes and benefits, methods of reimbursement. Lack of insurance coverage, unavailability of CR centers in the community and low physicians’ fee were other factors reported by the physicians. Conclusion: Cardiologists’ inadequate general knowledge of and attitude toward CR programs seem to be a potential threat for cardiac prevention and rehabilitation in some societies.

To evaluate the factors of intraoperative retinal breaks in macular hole surgery. This study included 558 eyes of 506 patients who underwent idiopathic macular hole surgery by one surgeon. Multiple regression was performed using the variables of gender, age, affected eye, lens status, stage, duration of symptoms, hole size, axial length, and lattice degeneration. The rate of retinal breaks was higher in stage 3 (16.0%) than in stage 4 (8.2%) (p = 0.014). In eyes with lattice degeneration intraoperative retinal breaks occurred in about 40% of the cases. Major factors were as follows: lattice degeneration (r = 0.24, p lattice degeneration, and gender (r = -0.18, p = 0.035) in eyes of stage 4 without lattice degeneration. The factors of intraoperative retinal breaks in macular hole surgery were lattice degeneration in all eyes and stage 3 in eyes without lattice degeneration. The high incidence of intraoperative retinal breaks in stage 3 was mainly due to the occurrence of posterior vitreous detachment. Male gender was a significant factor associated with intraoperative retinal breaks.

The provision of supportive and palliative care for an indigenous people in Nova Scotia, Canada, was examined to further our understanding and thereby improve cultural competency. Most of Nova Scotia's indigenous people are Mi'kmaq. The Mi'kmaq Nation lives in Atlantic Canada as well as New England in the eastern USA. Themes were identified in the literature and through discussion with seven experts who have Mi'kmaq health and cultural research expertise. This paper has been reviewed and approved by two Mi'kmaq consultants who frequently speak on behalf of the Mi'kmaq people in relation to health and cultural understanding. Recommendations for non-indigenous care providers are presented. The themes identified focused on jurisdictional issues and cultural understanding. They are interconnected and grounded in the historic Mi'kmaq context of colonialism. Jurisdictional issues experienced by the Mi'kmaq affect access, continuity and appropriateness of care. Cultural concepts were associated with worldview, spirituality, the role of family and community relationships and communication norms, and thereby with the alignment of values and language in the provision of care. Three Mi'kmaq concepts are noted: apiksiktatulti, nemu'ltus and salite. Through reflection on the situation of Nova Scotia's Mi'kmaq, non-indigenous healthcare providers can assess how they might increase their cultural understanding in the provision of supportive and palliative care. Recommendations relate to the health system, relationships with individual persons and direction for research.

Poor outcomes after childbirth are associated with physical ill health and with an absence of a positive sense of well-being. Postnatally poor physical health is thought to be influenced by the care received, the nature of the birth, and associated complications. The aim of this study was to estimate the effects of a range of clinical and other factors on positive outcome and well-being 3 months after childbirth. This study used data on more than 5,000 women from a 2010 National Maternity Survey about their experiences of maternity care, and health and well-being 3 months after childbirth. Positive outcome was defined as women reporting no problems and feeling "very well" at the time of the survey. In the univariate analysis, several variables were significantly associated with positive outcome, including sociodemographic, antenatal, intrapartum, and postnatal factors. In the final logistic regression model, young mothers, those without physical disability and those with no or few antenatal or early postnatal problems, were most likely to have positive outcomes. Other significant factors included a positive initial reaction to the pregnancy, not reporting antenatal depression, fewer worries about the labor and birth, and access to information about choices for care. This study shows how positive outcomes for women after childbirth may be influenced by health, social, and care factors. It is important for caregivers to bear these factors in mind so that extra support may be made available to those women who are likely to be susceptible to poor outcome. © 2013, Copyright the Authors Journal compilation © 2013, Wiley Periodicals, Inc.
Full Text Available This paper analyzes the strategic role played by British classical political economy in constructing new technologies of power. Michel Foucault drew attention to a change that political economists promoted concerning the role of the state, which has been overlooked by historians of economic thought. This paper explores the main arguments provided by the most important British political economists of the 18th and 19th centuries on what concerns population management, State's role and economic dynamics in order to examine Foucault's considerations. Although British classical political economy consolidated the mechanism of markets and economic individuality, thus creating a system of truth that changed economic norms and practices, its discourse also established a political conduct that was responsible for creating mechanisms of control that disseminated new forms of power relations.
Full Text Available Over the past number of years, the public expenditures for childbirth-related leave benefits have more than doubled – in 2015 amounted to 0.7% GDP in relation to 0.3% GDP in 2002. This increase can mainly be attributed to the increased number of beneficiaries that grew consistently from 24 thousand in 2002 up to 40 thousand in 2015, despite the fact that the annual number of live births has been almost continually decreasing and the registered employment has dropped by almost 20 per cent in the observed period. One of the clear reasons explaining part of this increase is the extension of 3+ order of birth leaves in 2006, from one to two years, which can explain the increase of around 3.5 thousand of beneficiaries. Another reason is high number of beneficiaries using special child-care leave meant for parents with children with disabilities, but which, in reality, is very often used simply as the extension of parental leave. The average number of special child-care leave beneficiaries in the second half of 2015 amounted to 2.8 thousand. When these two effects are taken into account, we still notice significant increase of beneficiaries of around 10 thousand in the observed period. Fictitious employment during the pregnancy can explain this increase to some extent. Available data unambiguously show that a number of women formally employing during the second and third trimester of pregnancy has increased from 800 in 2002 to almost 3.5 thousand monthly average in the second half of 2015. There are two flaws of the childbirth-related leave programme in Serbia, which together lead to the constant increase of the number of beneficiaries. First is the lack of flexibility of the programme, both in terms of eligibility for acquiring the right as well as in terms of flexibility in use. Maternity/parental leave benefit may acquire only those in „standard employment” i.e. employed under employment contract (and entrepreneurs while other type of
Many retired coal miners who are eligible for care in a black lung treatment center at little or no cost to themselves do not enter into available programs or discontinue soon after beginning therapy. Reasons for this behavior are related to the prevalent beliefs among Appalachians concerning the course of black lung and the appropriate treatment for it. The miners' health beliefs are clearly at odds with those of the health care providers who work in the centers. Using the concept of explanatory model, popular and professional health cultures are analyzed, focusing on course of disease, sick role, appropriate treatment, and expected outcome. Differences in explanatory models are discussed with regard to implications for the organization and delivery of care to retired coal miners with black lung.
It is pointed out that electrosorption plays a key role in electrocatalysis. Little information is available, however, concerning the chemical nature of the interactions of the adsorbed species with the electrode and even less about the adsorption sites. The role of adsorbed species and surface layers in electrocatalysis is reviewed for several electrode systems. In recent years, some general insights have been achieved into the relationship of hydrogen electrode kinetics to hydrogen adsorption. For a given mechanism the exchange current density is related to the standard free energy of adsorption of the particular type of adsorbed hydrogen upon which the kinetics depend. The oxygen electrode reactions are less well understood than the reactions for the hydrogen electrode. The pronounced irreversibility of the oxygen electrode reactions at moderate temperatures has severely complicated mechanistic studies.
