    This study analyses, whether pictures of children showing a positive relationship are significantly different from those showing a negative one with respect to several criteria. The study involved a random selection of 45 children aged 4;6 to 11;6 years. The children painted a picture with themselves and a person they liked and a picture of themselves with someone they disliked. For the most part, the children drew pictures of themselves with peers both with respect to positive as well as negative images. In an interview afterwards, the children specified the criteria in their drawings by which the quality of the particular relationship can be identified. Positive and negative relationship paintings differ in the character of activity described. The sun as an element in children's paintings is painted not more frequent on positive compared to negative pictures. The colour black is used more often in the drawings signifying negative relationships. While girls used more colour in negative relationship drawings, boys used more colour in the positive ones. There was no significant difference in the use of favourite colours and decorative elements between the two groups. Only in negative relationship drawings people were looking away from each other. Smiling individuals were more common in the positive relationship pictures and in pictures painted by the 6 to 8 year olds. A greater distance between the individuals emerged on negative relationship drawings of the girls.

    2010-01-01

    A widely publicized but unpublished study of the relationship between gun shows and gun violence is being cited in debates about the regulation of gun shows and gun commerce. We believe the study is fatally flawed. A working paper entitled “The Effect of Gun Shows on Gun-Related Deaths: Evidence from California and Texas” outlined this study, which found no association between gun shows and gun-related deaths. We believe the study reflects a limited understanding of gun shows and gun markets and is not statistically powered to detect even an implausibly large effect of gun shows on gun violence. In addition, the research contains serious ascertainment and classification errors, produces results that are sensitive to minor specification changes in key variables and in some cases have no face validity, and is contradicted by 1 of its own authors’ prior research. The study should not be used as evidence in formulating gun policy. PMID:20724672

    Frontal cortical abnormalities and executive function impairment co-occur in bipolar disorder. Recent studies have shown that bipolar subtypes differ in the degree of structural and functional impairments. The relationships between cognitive performance and cortical integrity have not been clarified and might differ across patients with bipolar disorder type I, II, and healthy subjects. Using a vertex-wise whole-brain analysis, we investigated how cortical integrity, as measured by cortical thickness, correlates with executive performance in patients with bipolar disorder type I, II, and controls (N = 160). We found focal associations between executive function and cortical thickness in the medial prefrontal cortex in bipolar II patients and controls, but not in bipolar I disorder. In bipolar II patients, we observed additional correlations in lateral prefrontal and occipital regions. Our findings suggest that bipolar disorder patients show altered structure-function relationships, and importantly that those relationships may differ between bipolar subtypes. The findings are line with studies suggesting subtype-specific neurobiological and cognitive profiles. This study contributes to a better understanding of brain structure-function relationships in bipolar disorder and gives important insights into the neuropathophysiology of diagnostic subtypes. © 2018 The Authors Acta Psychiatrica Scandinavica Published by John Wiley & Sons Ltd.

  9. Leaf traits show different relationships with shade tolerance in moist versus dry tropical forests.

    2009-03-01

    Shade tolerance is the central paradigm for understanding forest succession and dynamics, but there is considerable debate as to what the salient features of shade tolerance are, whether adult leaves show similar shade adaptations to seedling leaves, and whether the same leaf adaptations are found in forests under different climatic control. Here, adult leaf and metamer traits were measured for 39 tree species from a tropical moist semi-evergreen forest (1580 mm rain yr(-1)) and 41 species from a dry deciduous forest (1160 mm yr(-1)) in Bolivia. Twenty-six functional traits were measured and related to species regeneration light requirements.Adult leaf traits were clearly associated with shade tolerance. Different, rather than stronger, shade adaptations were found for moist compared with dry forest species. Shade adaptations exclusively found in the evergreen moist forest were related to tough and persistent leaves, and shade adaptations in the dry deciduous forest were related to high light interception and water use.These results suggest that, for forests differing in rainfall seasonality, there is a shift in the relative importance of functional leaf traits and performance trade-offs that control light partitioning. In the moist evergreen forest leaf traits underlying the growth-survival trade-off are important, whereas in the seasonally deciduous forest leaf traits underlying the growth trade-off between low and high light might become important.

  10. The first sequenced carnivore genome shows complex host-endogenous retrovirus relationships.

    Directory of Open Access Journals (Sweden)

    Álvaro Martínez Barrio

    Full Text Available Host-retrovirus interactions influence the genomic landscape and have contributed substantially to mammalian genome evolution. To gain further insights, we analyzed a female boxer (Canis familiaris genome for complexity and integration pattern of canine endogenous retroviruses (CfERV. Intriguingly, the first such in-depth analysis of a carnivore species identified 407 CfERV proviruses that represent only 0.15% of the dog genome. In comparison, the same detection criteria identified about six times more HERV proviruses in the human genome that has been estimated to contain a total of 8% retroviral DNA including solitary LTRs. These observed differences in man and dog are likely due to different mechanisms to purge, restrict and protect their genomes against retroviruses. A novel group of gammaretrovirus-like CfERV with high similarity to HERV-Fc1 was found to have potential for active retrotransposition and possibly lateral transmissions between dog and human as a result of close interactions during at least 10.000 years. The CfERV integration landscape showed a non-uniform intra- and inter-chromosomal distribution. Like in other species, different densities of ERVs were observed. Some chromosomal regions were essentially devoid of CfERVs whereas other regions had large numbers of integrations in agreement with distinct selective pressures at different loci. Most CfERVs were integrated in antisense orientation within 100 kb from annotated protein-coding genes. This integration pattern provides evidence for selection against CfERVs in sense orientation relative to chromosomal genes. In conclusion, this ERV analysis of the first carnivorous species supports the notion that different mammals interact distinctively with endogenous retroviruses and suggests that retroviral lateral transmissions between dog and human may have occurred.

    The purpose of this study was to determine whether grain handlers underwent work-related changes in their pulmonary function and, if so, to examine the dose-effect relationships with dust exposure. The pulmonary function of grain handlers was measured at the beginning and end of work shifts over a period of one week, during which their exposure to dust was measured daily. The results showed changes indicative of a within-day obstructive change, in addition to a small restrictive defect occurring over the course of a week. Civic outside labourers who were examined as a control group showed a similar within-week obstructive change without any associated restriction of lung volume. The data on the grain handlers were also used to examine the dose-effect relationships of dust exposure, both on baseline pulmonary function and on within-day changes in these measurements. The baseline flow rates of workers who did not wear a mask were found to vary inversely with their average exposure to respirable dust. In addition, the flow rates underwent a within-day decrease that varied directly with their corresponding exposure to respirable dust and was unrelated to mask wearing. The median of the slopes for this relationship indicated that 50% of the subjects had a decrease of at least 923 ml/s in the value of their Vmax50%VC for each 1 mg/m3 increase in the concentration of respirable dust. Non-respirable dust did not have a measurable effect either on the baseline or the within-day changes in pulmonary function. The acute changes were unaffected by age, duration of employment, or extent of smoking. PMID:7138793

    To evaluate the performance of Comb-push Ultrasound Shear Elastography (CUSE) for classification of breast masses. CUSE is an ultrasound-based quantitative two-dimensional shear wave elasticity imaging technique, which utilizes multiple laterally distributed acoustic radiation force (ARF) beams to simultaneously excite the tissue and induce shear waves. Female patients who were categorized as having suspicious breast masses underwent CUSE evaluations prior to biopsy. An elasticity estimate within the breast mass was obtained from the CUSE shear wave speed map. Elasticity estimates of various types of benign and malignant masses were compared with biopsy results. Fifty-four female patients with suspicious breast masses from our ongoing study are presented. Our cohort included 31 malignant and 23 benign breast masses. Our results indicate that the mean shear wave speed was significantly higher in malignant masses (6 ± 1.58 m/s) in comparison to benign masses (3.65 ± 1.36 m/s). Therefore, the stiffness of the mass quantified by the Young's modulus is significantly higher in malignant masses. According to the receiver operating characteristic curve (ROC), the optimal cut-off value of 83 kPa yields 87.10% sensitivity, 82.61% specificity, and 0.88 for the area under the curve (AUC). CUSE has the potential for clinical utility as a quantitative diagnostic imaging tool adjunct to B-mode ultrasound for differentiation of malignant and benign breast masses.

  15. AREVA: Operating performance shows distinct improvement; Results heavily impacted by the cost of remedial measures

    2016-01-01

    The 2015 results illustrate the progress AREVA made in 2015 and open up favorable prospects for 2016 and the following years in view of its fundamentals. The group's competitiveness plan had a very positive impact on its costs and cash, despite the heavy net loss situation which continues and in a market environment that remained difficult in 2015. Half of this loss of 2 billion Euro is due to additional provisions for OL3 and half to provisions for restructuring and impairment related to market conditions. Concerning the group's liquidity, 2016 is funded and the capital increase which will be launched in the coming months will enable AREVA to gradually regain the group's positive profile. A new phase awaits the Group in 2016 with clarity and confidence in the implementation of the restructuring announced in 2015 and in particular the autonomy of AREVA NP and the creation of New AREVA

  16. Look who's cooking. Investigating the relationship between watching educational and edutainment TV cooking shows, eating habits and everyday cooking practices among men and women in Belgium.

    Television (TV) cooking shows have evolved from focusing on educating to focusing on entertaining, as well. At present, educational TV cooking shows focus on the transfer of cooking knowledge and skills, whereas edutainment TV cooking shows focus on entertaining their viewers. Both types of shows are ongoing success stories. However, little is known regarding the shows' links with the cooking and eating habits of their audiences. Therefore, the current study investigates the relationship between watching an educational or edutainment TV cooking show and one's cooking and eating habits. Given public health concerns regarding the decline in cooking behaviors and the simultaneous increase in caloric intake from food outside the home, this study suggests a promising intervention. The results of a cross-sectional survey in Belgium (n = 845) demonstrate that the audiences of educational and edutainment TV cooking shows do not overlap. Although there is little connection between watching specific shows and eating behavior, the connection between watching shows and cooking behaviors varies across gender and age lines. Behaviors also differ depending on whether the viewer is watching an educational or edutainment cooking show. For example, men of all ages appear to cook more often if they watch an educational show. However, only older men (above 38 years) seem to cook more often if they watch an edutainment TV show. The results demonstrate that the relationship between watching TV cooking shows and cooking habits warrants further investigation. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Objective - This research sought to develop a cognitive model that expresses how marketing professionals understand the relationship between the constructs that define relationship marketing (RM. It also tried to understand, using the obtained model, how objectives in this field are achieved. Design/methodology/approach – Through cognitive mapping, we traced 35 individual mental maps, highlighting how each respondent understands the interactions between RM elements. Based on the views of these individuals, we established an aggregate mental map. Theoretical foundation – The topic is based on a literature review that explores the RM concept and its main elements. Based on this review, we listed eleven main constructs. Findings – We established an aggregate mental map that represents the RM structural model. Model analysis identified that CLV is understood as the final result of RM. We also observed that the impact of most of the RM elements on CLV is brokered by loyalty. Personalization and quality, on the other hand, proved to be process input elements, and are the ones that most strongly impact others. Finally, we highlight that elements that punish customers are much less effective than elements that benefit them. Contributions - The model was able to insert core elements of RM, but absent from most formal models: CLV and customization. The analysis allowed us to understand the interactions between the RM elements and how the end result of RM (CLV is formed. This understanding improves knowledge on the subject and helps guide, assess and correct actions.

    AIM: To analyse reasons for and the nature of clinico-radiological contacts and their clinical impact. MATERIALS AND METHODS: Three different surveys were performed. (1) Data concerning contacts between staff radiologists (n = 20) and clinicians during 10 consecutive working days were collected; (2) staff clinicians (n = 174) filled in a questionnaire asking for their opinions about relationships with radiologists; (3) staff radiologists collected data about contacts with clinicians related to more urgent/complicated cases. Radiologists assessed the clinical impact of the radiological procedure and of the consultation. RESULTS: (1) During 220 working days 20 radiologists had a mean of 3.95 contacts per day (48.2% personal contacts, 51.8% telephone contacts), amounting to a personal total of 21.65 min per day. These contacts amounted to a total of 7.08 h per day, roughly one whole-time equivalent radiologist. (2) These consultations helped to refine the diagnostic strategy often (12.6%) or sometimes (71.4%) and to alter therapeutic decisions often (10.4%) or sometimes (56.6%). (3) The initial clinical diagnosis was changed in 50% of cases and the therapy was substantially changed on the basis of further radiological investigations and clinical-radiological discussion in 60% of cases. CONCLUSION: Clinical-radiological consultations are time consuming but have a beneficial diagnostic and therapeutic impact. Dalla Palma, L. (2000)

    To asses the effects of seminal plasma on sperm function. Retrospective case-control study. University hospital. One hundred fourteen infertile men. Acrobeads Test scores (0-4) and measurement of interleukin (IL)-6, soluble IL-6 receptor, epidermal growth factor, insulin-like growth factor-I (IGF-I), transforming growth factor-beta I, superoxide dismutase, calcitonin, and macrophage migration inhibitory factor (MIF) levels in seminal plasma. Kruskal-Wallis test to compare the concentrations of substances as a nonparametric test for differences among Acrobeads Test scores and a multivariable logistic regression model to find independent risk factors associated with abnormal Acrobeads Test results. The Acrobeads Test score was 0 for 7 samples, 1 for 20 samples, 2 for 18 samples, 3 for 28 samples, and 4 for 41 samples. Age, abstinence period, and semen parameters, except for sperm motility and percentage of sperm with abnormal morphology, had no effect on the Acrobeads Test results. Concentrations of IGF-I and MIF were significantly higher in patients with abnormal Acrobeads Test results. Multivariate analysis indicated that MIF and IGF-I were significantly associated with abnormal Acrobeads Test results (scores 0 to 1). Although further studies are needed, IGF-I and MIF in seminal plasma may have negative effects on sperm function.

Within the international business model...... of format adaptation, the musical talent show genre has been particularly successful in crossing cultural borders. Formats such as Idols, X Factor and Voice have sold to a large variety of countries, covering all continents. Such global reach inevitably raises the question of the genre’s audience appeal......; to what degree its reach has to do with a universal appeal inherent in the genre and/or the innovative character of individual formats, and to what degree its global success is due to local broadcasters’ ability to successfully adapt the formats to local audience tastes.

    Femoral neck fractures resulting from pregnancy-associated osteoporosis is a rare condition. Herein, we report an undoubted case of pregnancy-associated osteoporosis in a 38-year-old primiparous patient with pre-existing anorexia nervosa who suffered bilateral femoral neck fractures in the third trimester and early post-partum period. Magnetic resonance imaging revealed femoral neck fractures as well as diffuse marrow edema involving both femoral heads, which are considered under ordinary circumstances as characteristic imaging findings of transient osteoporosis of the hip. Based on our experience, we propose that pregnancy-associated osteoporosis might be present in femoral neck fractures attributed to transient osteoporosis of the hip in pregnancy. Conversely, bone status should be carefully and accurately estimated in cases of potential transient osteoporosis of the hip in pregnancy to reduce future fracture risk. © 2017 The Authors Journal of Obstetrics and Gynaecology Research published by John Wiley & Sons Australia, Ltd on behalf of Japan Society of Obstetrics and Gynecology.

    In situ measurements of atmospheric methane have been made over a 5-year period at Gale Crater on Mars using the Tunable Laser Spectrometer (TLS) instrument in the Sample Analysis at Mars (SAM) suite on the Curiosity rover. We report two important observations: (i) a background level of mean value of 0.41 ±0.11 (2sem) that is about 5 times lower than some model predictions based on generation from UV degradation of micro-meteorites or interplanetary dust delivered to the martian surface; (ii) "spikes" of elevated levels of 7 ppbv attributed to episodic releases from small local sources, probably to the north of Gale crater1. Reports of plumes, patches or episodic releases of methane in the Martian atmosphere have to date eluded explanation in part because of their lack of repeatability in time or location. Our in situ measurements of the background methane levels exhibit a strong, repeatable seasonal variability. The amplitude of the observed seasonal cycle is 3 times greater than both that expected from the annual sublimation and freezing of polar carbon dioxide and that expected from methane production from ultraviolet (UV) degradation of exogenously-delivered surface material. The observed large seasonal variation in the background, and sporadic observations of higher pulses of 7 ppbv appear consistent with localized small sources of methane release from Martian surface reservoirs that may be occurring throughout the planet. We will present our updated data set, correlations of Mars methane with various other measurements from SAM, REMS, RAD and ChemCam instruments on Curiosity, as well as empirical models of UV surface insolation, and provide preliminary interpretation of results. 1 "Mars Methane Detection and Variability at Gale Crater", C.

    2007-07-01

    Without visible results political support to an energy efficiency programme will dissolve in a few years. Therefore high-quality monitoring and reporting systems are essential to maintain a long-term commitment. Both in Finnish Energy Audit Programme (EAP), began in 1992, and in Voluntary Agreement Scheme (VA), began in 1997, bottom-up monitoring systems have been in place almost since the beginning. These policy measures and their monitoring systems are integrated. For the EAP monitoring system data is collected in three phases: subsidies granted; the energy auditing volumes in different sectors submitted EA reports; proposed measures and saving potentials. VA annual reporting; status of implementation of the proposed measures in EA reports and implementing rate for saving potentials. In VA scheme the companies and communities report annually on their energy consumption and on energy efficiency measures they have implemented or have decided to implement. Information on energy savings in energy units and energy costs as well as the required investment is reported in connection to the presented measures. The collected data is based on engineering calculations by the energy auditors. Since the companies have no incentives to submit exaggerated savings, the reported savings are equal to those figures the companies have used as criteria when deciding on the implementation of the measures. By 2005 these two policy measures have generated about 7 TWh annual savings, representing over 2 % of Finland's total energy end-use. In relation to the magnitude of savings brought in daylight, the investment on monitoring has really paid back.

    The importance of a life course approach to childhood obesity has been emphasized; however, few studies can prospectively investigate relationships in three-generation families. To prospectively investigate the relationship between grandparental and grandchild waist circumference (WC) at ages 5 and 9 down maternal and paternal lines. At baseline in the Lifeways Cross-Generation Cohort, 1094 children were born to 1082 mothers; 585 were examined at age 5 and 298 at age 9. Of the total 589 children with measured WC, data were also available from 745 grandparents. Child WC was standardized for age and sex, and theory-based hierarchical linear regression was used. Maternal grandmother (MGM) WC was predictive of grandchild WC at both time points. At age 5, grandchild's standardized birth weight (B = 0.266, p = 0.001), mother's means tested eligibility for free medical care (B = 1.029, p = 0.001) and grandchild seeing maternal grandparents daily (B = 0.312, p = 0.048) were significant alongside MGM WC (B = 0.015, p = 0.019). At age 9, only MGM WC (B = 0.022, p = 0.033) and mother's WC (B = 0.032, p = 0.005) were significant. Mediation analysis with mother's WC showed significant direct relationship of MGM and grandchild WC. This prospective cross-generational cohort shows consistent patterns of association between MGM and grandchild WC, not seen in other grandparental lineages. © 2018 World Obesity Federation.

Four hypotheses were tested in the context of Twitter through a 2×2 (presence: human vs. organizational×organization type: nonprofit vs. for-profit) within-subjects design. The results revealed that conversational human voice was perceived to be higher for Twitter pages of organizations with a human presence than for those with an organizational presence. Providing a human presence on social media through the use of social media managers' avatars and names appeared to promote favorable organization-public relationships and positive WOM communication. However, dialogic communication intentions did not significantly differ between organizations incorporating a human presence versus an organizational presence into their Twitter pages. The proposed dynamic role of human presence versus organizational presence adds a new perspective as to how organizations can take better advantage of interpersonal aspects of social media.

    This qualitative study examines the relationship between doctors and HIV-infected patients with regard to problems of adherence. Objective hermeneutics was used to analyze the scene of a doctor-patient conversation produced through psychodrama. Specific traits shared by the patients in question were a confused regulation of closeness and distance as well as a non-maintenance of the traditional asymmetry within the doctor-patient relation. The patients faced the doctors on a level of diffuse social relations and showed the tendency to involve the doctor into their community. The conclusion for a model explaining patients' adherence may be: it exist an individual level of the need for being accepted by the doctor as somebody particular. If this level is reached, i. e. individual claims are met and personal desires are satisfied, the patient will follow the physician's advice. Authors discuss whether the model is compatible with the conflict of self-esteem.

    Full Text Available The regulations for Protected Designation of Origin require a certification body to verify compliance with the provisions of the product specification. The grated Parmigiano-Reggiano is evaluated with a scorecard containing 21 quantitative descriptors and 4 qualitative evaluations of compliance with the regulations. To better understand the relationship between sensory compliance and quantitative descriptors we have tested 24 samples of grated Parmigiano-Reggiano. Correlations and Partial Least Squares gave us a better understanding of compliance evaluation. The work allowed us to define the most important descriptors in relationship with compliance and showed that it is possible to predict compliance values using descriptor values.

    Previous research has proposed that the approximate number system (ANS) constitutes a building block for later mathematical abilities. Therefore, numerous studies investigated the relationship between ANS acuity and mathematical performance, but results are inconsistent. Properties of the experimental design have been discussed as a potential explanation of these inconsistencies. In the present study, we investigated the influence of set size and presentation duration on the association between non-symbolic magnitude comparison and math performance. Moreover, we focused on strategies reported as an explanation for these inconsistencies. In particular, we employed a non-symbolic magnitude comparison task and asked participants how they solved the task. We observed that set size was a significant moderator of the relationship between non-symbolic magnitude comparison and math performance, whereas presentation duration of the stimuli did not moderate this relationship. This supports the notion that specific design characteristics contribute to the inconsistent results. Moreover, participants reported different strategies including numerosity-based, visual, counting, calculation-based, and subitizing strategies. Frequencies of these strategies differed between different set sizes and presentation durations. However, we found no specific strategy, which alone predicted arithmetic performance, but when considering the frequency of all reported strategies, arithmetic performance could be predicted. Visual strategies made the largest contribution to this prediction. To conclude, the present findings suggest that different design characteristics contribute to the inconsistent findings regarding the relationship between non-symbolic magnitude comparison and mathematical performance by inducing different strategies and additional processes.

    This study aims to analyse the non-linear relationship between Body Mass Index (BMI) and direct health care costs, and to quantify the resulting cost fraction attributable to obesity in Germany. Five cross-sectional surveys of cohort studies in southern Germany were pooled, resulting in data of 6757 individuals (31-96 years old). Self-reported information on health care utilisation was used to estimate direct health care costs for the year 2011. The relationship between measured BMI and annual costs was analysed using generalised additive models, and the cost fraction attributable to obesity was calculated. We found a non-linear association of BMI and health care costs with a continuously increasing slope for increasing BMI without any clear threshold. Under the consideration of the non-linear BMI-cost relationship, a shift in the BMI distribution so that the BMI of each individual is lowered by one point is associated with a 2.1% reduction of mean direct costs in the population. If obesity was eliminated, and the BMI of all obese individuals were lowered to 29.9 kg/m², this would reduce the mean direct costs by 4.0% in the population. Results show a non-linear relationship between BMI and health care costs, with very high costs for a few individuals with high BMI. This indicates that population-based interventions in combination with selective measures for very obese individuals might be the preferred strategy.

    Full Text Available Corporate Volunteering (CV is a phenomenon that emerged in the second half of the 20th century and began to grow and globalize at the beginning of the 21st century. There seems to be a consensus that the recent growth of Corporate Volunteering is related to the development and growing legitimacy of the concept of Corporate Social Responsibility (CSR. Nevertheless, the theoretical discussion on how the two concepts (Corporate Volunteering and Corporate Social Responsibility are related is just beginning, while empirical research on how this relationship operates in corporate practice is still incipient. This paper presents preliminary results of a research on this subject carried out in Uruguay in 2016. This is a statistical study that analyses the relationship between the application of corporate volunteering activities and the incorporation of a CSR approach to the management of companies. The incorporation of both types of practices is measured by a self-assessment questionnaire that includes 81 indicators (using a Likert scale to assess them, which were designed based on ISO 26000 Guidance of Social Responsibility. The questionnaire was administered to 96 companies, using a comparative analysis between those that practice Corporate Volunteering and those which do not. The results obtained allow us to support the hypothesis that the application of Corporate Volunteering is positively associated with the incorporation of CSR when managing the relationship between the company and its employees and also with the community. Moreover, these results contribute to a better understanding on how both concepts are related.

    To understand the longitudinal relationship between loneliness and isolation. Participants included 5,870 adults 65 years and older (M = 72.89 ± 5.59 years) from the first 5 years of the Cardiovascular Health Study. Loneliness was assessed using a dichotomized loneliness question. Social isolation was assessed using six items from the Lubben Social Network Scale. Yearly life events were included to assess abrupt social network changes. Mixed effects logistic regression was employed to analyze the relationship between isolation and loneliness. Higher levels of social isolation were associated with higher odds of loneliness, as was an increase (from median) in level of social isolation. Life events such as a friend dying were also associated with increased odds of loneliness. These results suggest that average level of isolation and increases in the level of isolation are closely tied to loneliness, which has implications for future assessment or monitoring of loneliness in older adult populations. © The Author(s) 2015.

    The objective of this study was to determine whether acculturation and psychosocial stress exert differential effects on body fat distribution and insulin resistance among native-born African Americans and African-Caribbean immigrants living in the US Virgin Islands (USVI). Data collected from a non-diabetic sample of 183 USVI-born African Americans and 296 African-Caribbean immigrants age > 20 on the island of St. Croix, USVI were studied. Information on demographic characteristics, acculturation and psychosocial stress was collected by questionnaire. Anthropometric measurements were taken, and serum glucose and insulin were measured from fasting blood samples. Insulin resistance was estimated by the homeostasis model assessment (HOMA) method. The results showed that in multivariate regression analyses, controlling for age, education, gender, BMI, waist circumference, family history of diabetes, smoking and alcohol consumption, acculturation was independently related to logarithm of HOMA (InHOMA) scores among USVI-born African Americans, but not among African-Caribbean immigrants. In contrast, among USVI-born African Americans psychosocial stress was not significantly related to InHOMA, while among African-Caribbean immigrants psychosocial stress was independently related to InHOMA in models that included BMI, but not in those which included waist circumference. This study suggests that acculturation and psychosocial stress may have a differential effect on body fat distribution and insulin resistance among native-born and immigrant blacks living in the US Virgin Islands.

We show that complete silencing of the transgenic expression of progerin normalized bone morphology and mineralization already after 7...... weeks. The improvements included lower frequencies of rib fractures and callus formation, an increased number of osteocytes in remodeled bone, and normalized dentinogenesis. The beneficial effects from resveratrol treatment were less significant and to a large extent similar to mice treated with sucrose...... alone. However, the reversal of the dental phenotype of overgrown and laterally displaced lower incisors in HGPS mice could be attributed to resveratrol. Our results indicate that the HGPS bone defects were reversible upon suppressed transgenic expression and suggest that treatments targeting aberrant...

    Some directional relationships between forces and accelerations in special relativity have been studied by considering the most general case of a body having x, y and z components of velocity, which is acted upon by a force with nonzero components. The behaviour of asub(y)/asub(x) and asub(y)/asub(z) vs. velocity for different force component ratios is studied in the general situation in which vsub(x) is unequal to vsub(y) is unequal to vsub(z). It is shown that one or two, suddenly varying, negative acceleration components can result for the body at sufficiently high velocities, and an explanation is given. (author)

    2016-01-01

    Full Text Available This essay examines the significance and transformation of shame in the context of digitalization, in particular, the psychosocial and psychological consequences of shifts in the boundaries between public and private manifest in the contemporary digital world. Moreover, it will examine the dynamic relationships of shame, humiliation and shamelessness as they develop in digital environments characterized by the dissolution of physical and communicative presence, as well as the, in turn, changing functions, ambivalences and affective pitfalls of self-presentation. On the basis of descriptions and commentaries by contemporary adolescents on the significance of social networks and on their own digital self-presentation, it will identify mechanisms for dealing with the imagined, projected or abnegated gaze of the other in the net.

    Hope (goal-directed thinking) and patient activation (knowledge and skills to manage one's illness) are both important in managing chronic conditions like schizophrenia. The relationship between hope and patient activation has not been clearly defined. However, hope may be viewed as a foundational, motivating factor that can lead to greater involvement in care and feelings of efficacy. The purpose of the present study was to understand the prospective relationship between hope and patient activation in a sample of adults with schizophrenia (N=118). This study was a secondary data analysis from a study on Illness Management and Recovery (IMR) - a curriculum-based approach to schizophrenia self-management. Data were collected at baseline (prior to any intervention), and at 9 and 18-month follow-up. As predicted, hope and patient activation were significantly related with each other, showing large positive concurrent correlations. Demographics and background characteristics were not significantly related to patient activation or hope. Longitudinal analyses found no specific directional effect, yet suggested that hope and patient activation mutually influence each other over time. Our findings add flexibility in designing recovery-based interventions - fostering hope may not be a pre-requisite for activating consumers to be more involved in their own care.

    Chagas disease, caused by the protozoa parasite Trypanosoma cruzi, is an example of extended parasitaemia with unmet medical needs. Current treatments based on old-featured benznidazole (Bz) and nifurtimox are expensive and do not fulfil the criteria of effectiveness, and a lack of toxicity devoid to modern drugs. In this work, a group of abietic acid derivatives that are chemically stable and well characterised were introduced as candidates for the treatment of Chagas disease. In vitro and in vivo assays were performed in order to test the effectiveness of these compounds. Finally, those which showed the best activity underwent additional studies in order to elucidate the possible mechanism of action. In vitro results indicated that some compounds have low toxicity (i.e. >150 μM, against Vero cell) combined with high efficacy (i.e. <20 μM) against some forms of T. cruzi. Further in vivo studies on mice models confirmed the expectations of improvements in infected mice. In vivo tests on the acute phase gave parasitaemia inhibition values higher those of Bz, and a remarkable decrease in the reactivation of parasitaemia was found in the chronic phase after immunosuppression of the mice treated with one of the compounds. The morphological alterations found in treated parasites with our derivatives confirmed extensive damage; energetic metabolism disturbances were also registered by (1)H NMR. The demonstrated in vivo activity and low toxicity, together with the use of affordable starting products and the lack of synthetic complexity, put these abietic acid derivatives in a remarkable position toward the development of an anti-Chagasic agent.

    Full Text Available Mutations in the valosin containing protein (VCP gene cause hereditary Inclusion body myopathy (hIBM associated with Paget disease of bone (PDB, frontotemporal dementia (FTD, more recently termed multisystem proteinopathy (MSP. Affected individuals exhibit scapular winging and die from progressive muscle weakness, and cardiac and respiratory failure, typically in their 40s to 50s. Histologically, patients show the presence of rimmed vacuoles and TAR DNA-binding protein 43 (TDP-43-positive large ubiquitinated inclusion bodies in the muscles. We have generated a VCPR155H/+ mouse model which recapitulates the disease phenotype and impaired autophagy typically observed in patients with VCP disease. Autophagy-modifying agents, such as rapamycin and chloroquine, at pharmacological doses have previously shown to alter the autophagic flux. Herein, we report results of administration of rapamycin, a specific inhibitor of the mechanistic target of rapamycin (mTOR signaling pathway, and chloroquine, a lysosomal inhibitor which reverses autophagy by accumulating in lysosomes, responsible for blocking autophagy in 20-month old VCPR155H/+ mice. Rapamycin-treated mice demonstrated significant improvement in muscle performance, quadriceps histological analysis, and rescue of ubiquitin, and TDP-43 pathology and defective autophagy as indicated by decreased protein expression levels of LC3-I/II, p62/SQSTM1, optineurin and inhibiting the mTORC1 substrates. Conversely, chloroquine-treated VCPR155H/+ mice revealed progressive muscle weakness, cytoplasmic accumulation of TDP-43, ubiquitin-positive inclusion bodies and increased LC3-I/II, p62/SQSTM1, and optineurin expression levels. Our in vitro patient myoblasts studies treated with rapamycin demonstrated an overall improvement in the autophagy markers. Targeting the mTOR pathway ameliorates an increasing list of disorders, and these findings suggest that VCP disease and related neurodegenerative multisystem

    Relational and organisational factors are key elements of interprofessional collaboration (IPC) and team climate. Few studies have explored the relationship between IPC and team climate. This article presents a study that aimed to explore IPC in primary healthcare teams and understand how the assessment of team climate may provide insights into IPC. A mixed methods study design was adopted. In Stage 1 of the study, team climate was assessed using the Team Climate Inventory with 159 professionals in 18 interprofessional teams based in São Paulo, Brazil. In Stage 2, data were collected through in-depth interviews with a sample of team members who participated in the first stage of the study. Results from Stage 1 provided an overview of factors relevant to teamwork, which in turn informed our exploration of the relationship between team climate and IPC. Preliminary findings from Stage 2 indicated that teams with a more positive team climate (in particular, greater participative safety) also reported more effective communication and mutual support. In conclusion, team climate provided insights into IPC, especially regarding aspects of communication and interaction in teams. Further research will provide a better understanding of differences and areas of overlap between team climate and IPC. It will potentially contribute for an innovative theoretical approach to explore interprofessional work in primary care settings.

    Full Text Available Background. Presumably, the academic stress that builds throughout the academic year has a negative effect on dental students’ psychological well-being and may have a relationship with academic performance. This research aimed to analyse the variation of positive well-being in second-year dental students, across the academic semester, in relation to consecutive examinations as part of academic assessment system (1 and to observe the relationship between academic performance during semester evaluation period and dental students’ positive well-being (2. Methods. A prospective study was conducted on second-year dental students, data on positive well-being being collected with WHO-Five Well-Being Index (WHO-5, at the beginning of the semester and after three consecutive mandatory examinations. Results. One hundred and forty-six dental students were included (77% response rate. Repeated ANOVA showed a significant progressive decline of positive well-being over the semester, which was clinically significant for an important part of them. Students who performed better in the semester evaluation period registered higher well-being levels at the beginning of the semester but a more pronounced decline of it until the semester evaluation period. Conclusion. Based on this research, a relationship between positive well-being, academic assessments, and academic performance is suggested, when evaluating them in a prospective frame.

Adverse childhood experiences (ACEs such as abuse and dysfunctional home environments show strong cumulative relationships with physical and mental illness yet less is known about their effects on mental well-being in the general population. Methods A nationally representative household survey of English adults (n = 3,885 measuring current mental well-being (Short Edinburgh-Warwick Mental Well-being Scale SWEMWBS and life satisfaction and retrospective exposure to nine ACEs. Results Almost half of participants (46.4 % had suffered at least one ACE and 8.3 % had suffered four or more. Adjusted odds ratios (AORs for low life satisfaction and low mental well-being increased with the number of ACEs. AORs for low ratings of all individual SWEMWBS components also increased with ACE count, particularly never or rarely feeling close to others. Of individual ACEs, growing up in a household affected by mental illness and suffering sexual abuse had the most relationships with markers of mental well-being. Conclusions Childhood adversity has a strong cumulative relationship with adult mental well-being. Comprehensive mental health strategies should incorporate interventions to prevent ACEs and moderate their impacts from the very earliest stages of life.

    Muscle mass maybe a determining factor in the variability of spirometry results in individuals of the same sex and age who have similar anthropometric characteristics. The aim of this study was to determine the association between spirometric results from healthy individuals and their muscle mass assessed by dual energy X-ray absorptiometry (DEXA). A sample of 161 women and 144 men, all healthy non-smokers, was studied. Ages ranged from18 to77years. For each subject, spirometry results and total and regional lean mass values obtained by full body DEXA were recorded. A descriptive analysis of the variables and a regression analysis were performed to study the relationship between spirometric variables and lean body mass, correcting for age and body mass index (BMI). In both sexes all muscle mass variables correlated positively and significantly with spirometric variables, and to a greater extent in men. After partial adjustment of correlations by age and BMI, the factor which best explains the spirometric variables is the total lean body mass in men, and trunk lean body mass in women. In men, muscle mass in the lower extremities is most closely associated with spirometric results. In women, it is the muscle mass of the trunk. In both sexes muscle mass mainly affects FEV 1 .

    The study purpose was to determine relationships between results of internal and external match load determining methods. Twenty-one players, who participated in selected badminton championships during the 2014/2015 season served as subjects. The heart rate (HR) values and GPS data of each player were obtained via a fix Polar HR Transmitter Belt and MinimaxX GPS device. Moderate significant Spearman's rank correlations were found between HR and absolute duration (r = 0.43 at a low intensity (LI) and 0.44 at a high intensity (HI)), distance covered (r = 0.42 at a HI) and player load (PL) (r = 0.44 at a HI). Results also revealed an opposite trend for external and internal measures of load as the average relative HR value was found to be the highest for the HI zone (54.1%) compared to the relative measures of external load where average values (1.29-9.89%) were the lowest for the HI zone. In conclusion, our findings show that results of an internal and external badminton match load determining method are more related to each other in the HI zone than other zones and that the strength of relationships depend on the duration of activities that are performed in especially LI and HI zones. Overall, trivial to moderate relationships between results of an internal and external match load determining method in male, singles badminton players reaffirm the conclusions of others that these constructs measure distinctly different demands and should therefore be measured concurrently to fully understand the true requirements of badminton match play.

    Sickle cell anaemia (SCA) is associated with chronic anaemia and oxygen desaturation, which elevate cerebral blood flow (CBF) and increase the risk of neurocognitive complications. Arterial spin labelling (ASL) provides a methodology for measuring CBF non-invasively; however, ASL techniques using only a single inflow time are not sufficient to fully characterize abnormal haemodynamic behaviour in SCA. This study investigated haemodynamic parameters from a multi-inflow-time ASL acquisition in younger (8-12 years) and older (13-18 years) children with SCA with and without silent cerebral infarction (SCI+/-) (n = 20 and 19 respectively, 6 and 4 SCI+ respectively) and healthy controls (n = 9 and 7 respectively). Compared with controls, CBF was elevated globally in both groups of patients. In the younger SCA patients, blood oxygen content was negatively correlated with CBF in the middle and posterior cerebral artery territories and significantly positively correlated with bolus arrival time (BAT) in the anterior and middle cerebral artery territories. In older children, SCA patients had significantly shorter BAT than healthy controls and there was a significant negative correlation between CBF and oxygen content only in the territory of the posterior cerebral artery, with a trend for a correlation in the anterior cerebral artery but no relationship for the middle cerebral artery territory. In the younger group, SCI+ patients had significantly higher CBF in the posterior cerebral artery territory (SCI+ mean = 92.78 ml/100 g/min; SCI- mean = 72.71 ml/100 g/min; F = 4.28, p = 0.04), but this no longer reached significance when two children with abnormal transcranial Doppler and one with haemoglobin SC disease were excluded, and there were no significant differences between patients with and without SCI in the older children. With age, there appears to be increasing disparity between patients and controls in terms of the relationship between CBF and oxygen

    2012-03-01

    Posttraumatic stress disorder's (PTSD) latent structure has been widely debated. To date, two four-factor models (Numbing and Dysphoria) have received the majority of factor analytic support. Recently, Elhai et al. (2011) proposed and supported a revised (five-factor) Dysphoric Arousal model. Data were gathered from two separate samples; War veterans and Primary Care medical patients. The three models were compared and the resultant factors of the Dysphoric Arousal model were validated against external constructs of depression and anxiety. The Dysphoric Arousal model provided significantly better fit than the Numbing and Dysphoria models across both samples. When differentiating between factors, the current results support the idea that Dysphoric Arousal can be differentiated from Anxious Arousal but not from Emotional Numbing when correlated with depression. In conclusion, the Dysphoria model may be a more parsimonious representation of PTSD's latent structure in these trauma populations despite superior fit of the Dysphoric Arousal model.

    Vaporization enthalpy of an ionic liquid (IL) is a key physical property for applications of ILs as thermofluids and also is useful in developing liquid state theories and validating intermolecular potential functions used in molecular modeling of these liquids. Compilation of the data for a homologous series of 1-alkyl-3-methylimidazolium bis(trifluoromethane-sulfonyl)imide ([C(n)mim][NTf2]) ILs has revealed an embarrassing disarray of literature results. New experimental data, based on the concurring results from quartz crystal microbalance, thermogravimetric analyses, and molecular dynamics simulation have revealed a clear linear dependence of IL vaporization enthalpies on the chain length of the alkyl group on the cation. Ambiguity of the procedure for extrapolation of vaporization enthalpies to the reference temperature 298 K was found to be a major source of the discrepancies among previous data sets. Two simple methods for temperature adjustment of vaporization enthalpies have been suggested. Resulting vaporization enthalpies obey group additivity, although the values of the additivity parameters for ILs are different from those for molecular compounds.

  13. Neural Progenitors in the Developing Neocortex of the Northern Tree Shrew (Tupaia belangeri Show a Closer Relationship to Gyrencephalic Primates Than to Lissencephalic Rodents

    Directory of Open Access Journals (Sweden)

    Full Text Available The neocortex is the most complex part of the mammalian brain and as such it has undergone tremendous expansion during evolution, especially in primates. The majority of neocortical neurons originate from distinct neural stem and progenitor cells (NPCs located in the ventricular and subventricular zone (SVZ. Previous studies revealed that the SVZ thickness as well as the abundance and distribution of NPCs, especially that of basal radial glia (bRG, differ markedly between the lissencephalic rodent and gyrencephalic primate neocortex. The northern tree shrew (Tupaia belangeri is a rat-sized mammal with a high brain to body mass ratio, which stands phylogenetically mid-way between rodents and primates. Our study provides – for the first time – detailed data on the presence, abundance and distribution of bRG and other distinct NPCs in the developing neocortex of the northern tree shrew (Tupaia belangeri. We show that the developing tree shrew neocortex is characterized by an expanded SVZ, a high abundance of Pax6+ NPCs in the SVZ, and a relatively high percentage of bRG at peak of upper-layer neurogenesis. We further demonstrate that key features of tree shrew neocortex development, e.g., the presence, abundance and distribution of distinct NPCs, are closer related to those of gyrencephalic primates than to those of ferret and lissencephalic rodents. Together, our study provides novel insight into the evolution of bRG and other distinct NPCs in the neocortex development of Euarchontoglires and introduces the tree shrew as a potential novel model organism in the area of human brain development and developmental disorders.

    The term 'B.A.S.E jump' refers to jumping from a building, antenna, span (i.e., bridge) or earth (i.e., cliff) structure, and parachuting to the ground. There are numerous hazards associated with B.A.S.E jumps which often result in injury and, occasionally, fatality. This case report details the skeletal trauma resulting from a fatal B.A.S.E jump in Australia. In this case, the jumper impacted the ground from a fall of 439m in a feet-first landing position, as a result of a partially deployed parachute, under extreme vertical deceleration. Skeletal trauma was analyzed using full-body post mortem computed tomography (PMCT) and contextual information related to the circumstances of the jump as reported by the Coroner. Trauma to 61 skeletal elements indicates the primary impact was to the feet (i.e., feet-first landing), followed by an anterior impact to the body (i.e., fall forwards). Details of the individual fracture morphologies indicate the various forces and biomechanics involved in this fall event. This case presents the types of fractures that result from a B.A.S.E jump, and highlights the value of using PMCT and coronial data as tools to augment skeletal trauma interpretations.

    Lindlbauer, Ivonne; Schreyögg, Jonas

    2014-12-01

    This study investigated the relationship between hospital specialization and technical efficiency using different measures of specialization, including two novel approaches based on patient volumes rather than patient proportions. It was motivated by the observation that most studies to date have quantified hospital specialization using information about hospital patients grouped into different categories based on their diagnosis, and in doing so have used proportions-thus indirectly assuming that these categories are dependent on one other. In order to account for the diversification of organizations and the idea that hospitals can be specialized in terms of professional expertise or technical equipment within a given diagnosis category, we developed our two specialization measures based on patient volume in each category. Using a one-step stochastic frontier approach on randomly selected data from the annual reports of 1,239 acute care German hospitals for the years 2000 through 2010, we estimated the relationship of inefficiency to exogenous variables, such as specialization. The results show that specialization as quantified by our novel measures has effects on efficiency that are the opposite of those obtained using earlier measures of specialization. These results underscore the importance of always providing an exact definition of specialization when studying its effects. Additionally, a Monte Carlo simulation based on three scenarios is provided to facilitate the choice of a specialization measure for further analysis.

    In asthma patients, the assessment of activity limitation is based on questions evaluating how limited the patient feels in their activities. However, the lack of functional data complicates the interpretation of the answers. We aimed to evaluate the intensity of relationships between the patient's perception of activity limitation and the results of several functional tests. Twenty patients complaining of asthma exacerbation were invited to complete three scores (Chronic Respiratory Disease questionnaire, Asthma Control Questionnaire, Hospital Anxiety and Depression scale). They also underwent lung function measurements, a 6-minute walk test and a cardio-pulmonary exercise test. In addition, physical activity was studied by actigraphy. Spearman's rank correlation coefficients between the patient's perception of activity limitation and each of the other parameters were analysed. Five parameters were significantly correlated with the perception of activity limitation: ACQ question 4, related to dyspnea (rs 0.74, p perception of activity limitation. In response to questions about limitation of activity, patients do not specifically answer mentioning physical limitation but rather the psychological burden associated with this constraint.

    Stent-assisted coil embolization (SACE) is used to address wide-necked or complex aneurysms. However, as they may recanalize after SACE, predictors of recanalization are needed. We investigated the relationship between follow-up angiographic results and the morphology of sidewall (SW) aneurysms in patients treated by SACE. Between September 2010 and September 2014, we performed 80 SACE procedures for SW intracranial aneurysms. Angiographic findings, obtained immediately after the procedure, 3-6 months thereafter, and when aneurysmal recanalization was suspected on MR angiogram scan, were recorded. Morphologically, the SW aneurysms were classified as "outside" (OS) and "partially inside" (PI) based on the curve of the axes of the proximal or distal parent artery with respect to the aneurysmal neck. Follow-up angiographic studies on OS- and PI SW aneurysms were compared. On the initial angiograms, we classified 42 aneurysms as OS and 38 as PI. Immediately after SACE, there was no significant difference in the angiographic findings on OS and PI aneurysms. However, on follow-up angiograms, there was a significant difference in the rate of spontaneous improvement (4 of 42 [OS] versus 21 of 38 [PI], P = .001). We performed additional coil embolization to treat 3 recanalized OS aneurysms. SW aneurysms classified morphologically as PI tended to occlude progressively even after incomplete occlusion by SACE. In contrast, aneurysms classified as OS must be observed carefully after SACE. Copyright © 2016 National Stroke Association. Published by Elsevier Inc. All rights reserved.

    Anterior cervical diskectomy and fusion (ACDF) is a well-established surgical treatment for radiculopathy and myelopathy. Previous studies showed that empty PEEK cages have lower radiographic fusion rates, but the clinical relevance remains unclear. This paper's aim is to provide high-quality evidence on the outcomes of ACDF with empty PEEK cages and on the relevance of radiographic fusion for clinical outcomes. This large prospective multicenter clinical trial performed single-level ACDF with empty PEEK cages on patients with cervical radiculopathy or myelopathy. The main clinical outcomes were VAS (0-10) for pain and NDI (0-100) for functioning. Radiographic fusion was evaluated by two investigators for three different aspects. The median (range) improvement of the VAS pain score was: 3 (1-6) at 6 months, 3 (2-8) at 12 months, and 4 (2-8) at 18 months. The median (range) improvement of the NDI score was: 12 (2-34) at 6 months, 18 (4-46) at 12 months, and 22 (2-44) at 18 months. Complete radiographic fusion was reached by 126 patients (43%) at 6 months, 214 patients (73%) at 12 months, and 241 patients (83%) at 18 months. Radiographic fusion was a highly significant ( p  PEEK cages is slow and insufficient. Lack of complete radiographic fusion leads to less improvement of pain and disability.

    Although legally anchored, there are no empirical results from German second opinion programs. In this study, various aspects within a population of a second opinion program are examined. In this study patients were analyzed who sought a second opinion in the period from August 2011 to December 2016. Differences in patient characteristics, differentiated by agreement of first and second opinion, were analyzed using multivariate logistic regression. Patients' satisfaction and quality of life were examined one, three and six months after obtaining the second opinion. In total, 1,414 patients sought a second opinion. Most frequent medical indications were the knee (38.7 %), the back (26.8 %), the hip (11.7 %), and the shoulder (10.2 %). Except for the indication (p=0.035), no patient characteristic had influence on the conformation of the second opinion. Approximately two out of three initial recommendations were not confirmed by the specialists. 89 % of the patients were satisfied or very satisfied with the second opinion and the service offered. The second opinion offers patients the opportunity to seek an additional independent medical opinion and thus provide support for decision making. Further research is needed to examine the reasons for the high discrepancies between the first and second opinions. Copyright © 2018. Published by Elsevier GmbH.

  3. Relationships between Unemployment and Economic Growth - the Review (Results of the Theoretical and Empirical Research

    2015-04-01

    Full Text Available The article aims to discuss the relationship between economic growth and unemployment as well as related determinant factors based on literature review. The traditional approach presents this relationship through the prism of the effects of creation, capitalization, pool of savings and creative destruction. Nowadays, an increasing number of researchers attach more importance to the impact of institutional factors, such as minimum and efficiency wages or the flexibility of the labor market. Both theoretical and empirical research reveal both the evolution of the relevant views and the lack of consistency between the concepts explaining the relationship between economic growth and unemployment in different regions of the world and in different groups of countries.

    2013-06-20

    The aim of our work is to present the universality of burnout syndrome among physicians worldwide and to demonstrate selected aspects of the relationship between patients and doctors as a common factor predisposing to burnout. We looked up 20 original pieces of research from the Medline database published in the last 10 years to determine the prevalence of burnout among doctors in different countries. In all quoted works a remarkable percentage of doctors of interventional and non-interventional specialties suffered burnout. Because it is the relationship with patients that constitutes a key denominator for their work, in the discussion we have exposed an important aspect of it, destructive patient games, described on the basis of transactional analysis. Since universal burnout causes a deterioration of doctors' service, for the optimal good of the patient to survive preservation of the doctor's well-being in the patient-doctor relationship is needed everywhere.

    This study aimed to test the theoretical relationships between smell identification and cognitive tasks based on existing neuroimaging and anatomical findings. Utilizing data collected from a memory assessment clinic, theory-derived mediation and moderation models were tested. The sample used in this study consisted of 103 (39 male, 64 female) individuals referred for memory assessments. The sample's mean education was 12.4 years (SD = 3.2), and the mean age of the sample was 77.2 years (SD = 6.3). The University of Pennsylvania Smell Identification Test (UPSIT) was a significant, partial mediator of the relationship between the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) Immediate and Delayed Memory indexes. Olfactory identification did not mediate list learning and retrieval; however, olfactory identification was a significant partial mediator of the relationship between story encoding and later memory retrieval of the story. Olfactory identification also fully mediated the relationship between a visuospatial construction task and its reconstruction from memory after a short delay. The relationship between processing speed and the olfactory identification was significantly mediated by semantic memory. Finally, the UPSIT moderated the relationship between a measure of premorbid ability, the Wechsler Test of Adult Reading, and current global cognitive functioning. Our results support theoretical relationships between olfaction and neuropsychological domains. Additionally, our results suggest that the UPSIT may serve as a proxy for cerebral integrity and is likely related to the duration of neurodegeneration.

    Relationship education represents a promising, nonstigmatizing approach to promoting the health and stability of same-sex couples. A new culturally sensitive adaptation of relationship education was developed specifically for female same-sex couples (The Strengthening Same-Sex Relationships Program, Female version; SSSR-F). SSSR-F includes adaptations of evidence-based strategies to build core relationship skills (e.g., communication skills training) as well as new content to address unique challenges faced by this population (e.g., discrimination; low social support). A small randomized waitlist-control trial (N = 37 couples) was conducted to evaluate program feasibility, acceptability, and efficacy. Three proximal outcomes targeted by SSSR-F (communication, perceived stress, social support) and 3 distal outcomes (global relationship satisfaction, instability, and confidence) were assessed at pre- and posttreatment and 3-month follow-up. Results of multilevel models accounting for nonindependence in dyadic data indicated statistically significant program effects on positive and negative couple communication, relationship satisfaction, and relationship confidence and small, nonsignificant program effects on stress, social support, and relationship instability. Analyses of follow-up data suggest maintenance of effects on the proximal but not the distal outcomes. Ratings of program satisfaction were high. Overall, findings support the feasibility, acceptability, and initial efficacy of SSSR-F, highlighting the potential value of culturally sensitive relationship education for same-sex couples. Continued efforts are needed to increase sustainability of program effects on global relationship quality over time. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    Bariatric surgery is a life-changing treatment for patients with severe obesity, but little is known about its association with interpersonal relationships. To investigate if relationship status is altered after bariatric surgery. Changes in relationship status after bariatric surgery were examined in 2 cohorts: (1) the prospective Swedish Obese Subjects (SOS) study, which recruited patients undergoing bariatric surgery from September 1, 1987, to January 31, 2001, and compared their care with usual nonsurgical care in matched obese control participants; and (2) participants from the Scandinavian Obesity Surgery Registry (SOReg), a prospective, electronically captured register that recruited patients from January 2007 through December 2012 and selected comparator participants from the general population matched on age, sex, and place of residence. Data was collected in surgical departments and primary health care centers in Sweden. The current analysis includes data collected up until July 2015 (SOS) and December 2012 (SOReg). Data analysis was completed from June 2016 to December 2017. In the SOS study, information on relationship status was obtained from questionnaires. In the SOReg and general population cohort, information on marriage and divorce was obtained from the Swedish Total Population Registry. The SOS study included 1958 patients who had bariatric surgery (of whom 1389 [70.9%] were female) and 1912 matched obese controls (of whom 1354 [70.8%] were female) and had a median (range) follow-up of 10 (0.5-20) years. The SOReg cohort included 29 234 patients who had gastric bypass surgery (of whom 22 131 [75.6%] were female) and 283 748 comparators from the general population (of whom 214 342 [75.5%] were female), and had a median (range) follow-up of 2.9 (0.003-7.0) years. In the SOS study, the surgical patients received gastric banding (n = 368; 18.8%), vertical banded gastroplasty (n = 1331; 68.0%), or gastric bypass (n = 259; 13

    Full Text Available The objectives of this study were related to the research of the relations between the abilities of professional basketball players in the performance of one repetition maximum (1RM back squat and explosive movements, such as 5, 10 and 20-metre running, and vertical jump; as well as the detection and comparison of these abilities between players who play on the outside and inside positions. The study involved 35 professional basketball players (22 outside and 13 inside who were selected as candidates for the national team of Bulgaria. Independent variables of muscular strength were obtained by applying the 1RM back squat test (142.06 ± 29.31 kg, and were normalized with respect to the body mass (1RM Squat/kg (1.51 ± 0.25 and by applying suitable allometric exponent (1RM SquatAl (6.86 ± 1.16. Dependent variables were obtained using two tests: 20-metre run (times registered at 5 and 10 metres and vertical jump (used to calculate the variable peak anaerobic power (PAPW. The results indicated that none of the variables of strength were significantly related to the speed performance, while moderate correlations occurred between the normalized strength variables (1RM Squat/kg and 1RM SquatAl and vertical jump (r = 0.310 and r = 0.308 / p < 0.05. The results obtained show greater correlation (r = 0.660 / p < 0.01 in the ability to deliver power when performing squat and mechanical work performed in vertical jumps. Outside and inside players were significantly different in three variables only: peak anaerobic power, body height and body weight.

    showed low but significant correlations with patient-related aspects like coping with disease, health-related knowledge and former positive experiences with physicians. A stepwise regression analysis revealed that interaction quality seems to contribute to enhanced treatment results independently of patients' competences. Our results suggest a positive relationship between perceived interaction quality as defined by the P.A.INT-Questionnaire and treatment effects 6 months after discharge. Comparisons of patient and physician evaluations showed that physicians seem to be successful in building relationships on the affective level but less successful on the instrumental level (i. e., information, structuring and reinforcement). Our data underline the importance of interaction quality for the success of rehabilitation and thus the importance of specific skills such as providing and collecting information, recognizing patients' concerns and goals as well as reinforcement of health-related action. This is especially important when knowledge of disease and coping with disease on patients' side is poor. Interaction quality seems to contribute to better treatment results independently of patients' competences. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Abstract Background Since Fuchs' report in 1999, the reported protective effect of dietary fiber from colorectal carcinogenesis has led many researchers to question its real benefit. The aim of this study is to evaluate the association between diet, especially dietary fiber and fat and colorectal cancer in Japan. Methods A multiple regression analysis (using the stepwise variable selection method was performed using the standardized mortality ratios (SMRs of colon and rectal cancer in 23 Japanese prefectures as objective variables and dietary fiber, nutrients and food groups as explanatory variables. Results As for colon cancer, the standardized partial correlation coefficients were positively significant for fat (1,13, P = 0.000, seaweeds (0.41, P = 0.026 and beans (0.45, P = 0.017 and were negatively significant for vitamin A (-0.63, P = 0.003, vitamin C (-0.42, P = 0.019 and yellow-green vegetables (-0.37, P = 0.046. For rectal cancer, the standardized partial correlation coefficient in fat (0.60, P = 0.002 was positively significant. Dietary fiber was not found to have a significant relationship with either colon or rectal cancers.

    Full Text Available The Internet has changed media fandom in two main ways: it helps fans connect with each other despite physical distance, leading to the formation of international fan communities; and it helps fans connect with the creators of the TV show, deepening the relationship between TV producers and international fandoms. To assess whether Italian fan communities active online are indeed part of transnational online communities and whether the Internet has actually altered their relationship with the creators of the original text they are devoted to, qualitative analysis and narrative interviews of 26 Italian fans of American TV shows were conducted to explore the fan-producer relationship. Results indicated that the online Italian fans surveyed preferred to stay local, rather than using geography-leveling online tools. Further, the sampled Italian fans' relationships with the show runners were mediated or even absent.

This study uses citizen science to investigate national-scale patterns in the distribution and abundance of selected lichen species on tree trunks and branches, and to relate these to air pollution and climate. Volunteers collected data for nine lichen indicators on 19,334 deciduous trees. Submitted data provided information on species-level patterns, and were used to derive composite lichen indices. Multiple linear regression and ANCOVA were used to model the relationships between lichen response variables on Quercus spp. and pollution, climate and location. The study demonstrated significant relationships between patterns in indicator lichens and levels of N- and S-containing pollutants on trunks and twigs. The derived lichen indices show great potential as a tool to provide information on local, site-specific levels of air quality. -- Highlights: •Data on presence and abundance of selected lichens were collected by members of the public. •Indicator species and indices were modelled against air pollution and climate data. •Lichens and indices show significant relationships with nitrogenous air pollution. •Lichen indices are useful tools for providing information on local air quality. -- Data on selected lichen taxa collected by members of the public in England is used to show the relationship of indicator taxa and pollution indices to air pollution and climate data

    In quarter milk samples from 2,492 randomly sampled cows that were selected without regard to their current or previous udder health status, the relationships between the following outcome variables were studied: treatment of clinical mastitis; the joint event of either treatment or culling for mastitis; culling for all reasons; culling specifically for mastitis; and the covariates of positive milk culture for Staphylococcus aureus, Streptococcus spp., and coagulase-negative Staphylococcus spp., or other pathogens, or of negative culture for mastitis pathogens. Microbiological diagnoses were assigned at the cow level, and altogether 3,075 diagnoses were related to the outcome variables. The relation between the absence of pathogens and rich (>1,500 cfu/mL of milk) or sparse (mastitis was greater for cows diagnosed with Staph. aureus compared with cows with no pathogens in all analyses. Cows with sparse growth of Staph. aureus upon microbiological analysis were more likely to be treated for clinical mastitis, and cows with rich growth of the bacteria experienced a higher overall risk of culling when the models adjusted for cow composite milk somatic cell count. No difference between rich and sparse growth of Staph. aureus was found when mastitis was defined as the joint event of either culling for mastitis or treatment of clinical mastitis, and when the relationship with culling specifically for mastitis was assessed. The combined outcome of treatment and culling for mastitis was related to a positive diagnosis of Strep. spp. after cow composite milk somatic cell count was omitted from the model. Presence of Streptococcus spp. was also related to culling specifically for mastitis, whereas culling for all reasons and treatment of clinical mastitis was not related to a positive culture of Strep. spp. Presence of coagulase-negative Staph. spp. or other pathogens was not associated with either of the outcome variables.

    To assess the relationship between the degree of leukoaraiosis (LA), carotid intima-media thickness (IMT) and intima-media thickness variability (IMTV). Sixty-one consecutive patients, who underwent a brain MRI examination and a carotid artery ultrasound, were included in this retrospective study, which conformed with the Declaration of Helsinki. Written informed consent was waived. In each patient, right/left carotid arteries and brain hemispheres were assessed using automated software for IMT, IMTV and LA volume. The mean hemispheric LA volume was 2,224 mm{sup 3} (SD 2,702 mm{sup 3}) and there was no statistically significant difference in LA volume between the right and left hemispheres (p value = 0.628). The mean IMT and IMTV values were 0.866 mm (SD 0.170) and 0.143 mm (SD 0.100), respectively, without significant differences between the right and left sides (p values 0.733 and 0.098, respectively). The correlation coefficient between IMTV and LA volume was 0.41 (p value = 0.0001), and 0.246 (p value = 0.074) between IMT and LA volume. IMTV significantly correlates with LA volume. Further studies are warranted to verify whether this parameter can be used clinically as a marker of cerebrovascular risk. (orig.)

    Full Text Available Leaving children at home alone is considered a form of “neglect” in most developed countries. In Japan, this practice is not prohibited, probably because this country is considered to have relatively safe communities for children. The impact of leaving children at home alone on their mental health is a controversial issue, and few studies have examined it to date. The aim of this study was to examine the impact of leaving children aged 6 or 7 years at home alone on their mental health, focusing on both the positive and negative aspects; that is, resilience, difficult behavior, and prosocial behavior. Data from the Adachi Child Health Impact of Living Difficulty (A-CHILD study were used. The caregivers of all children in the first grade in Adachi City, Tokyo, were targeted, of whom 80% completed the questionnaire (n = 4,291. Among the analytical sample which comprises those who completed both exposure and outcome variables (n = 4,195, 2,190 (52.2% children had never been left at home alone, 1,581 (37.7% children were left at home alone less than once a week, and 424 (10.1% children were left at home alone once a week or more. Child resilience was measured using the Children's Resilient Coping Scale, and difficult behavior (emotional symptoms, conduct problems, hyperactivity/inattention, and peer relationship problems and prosocial behavior using the Strength and Difficulty Questionnaire. Multivariate regression analyses were performed to examine the dose-response association between leaving children at home alone and child mental health, followed by propensity-score matching as a pseudo-randomized controlled trial to reduce potential confounding. The results showed that leaving children at home alone once a week or more, but not less than once a week, was associated with total difficulties scores, especially conduct problems, hyperactivity/inattention, and peer relationship problems. These findings indicate that leaving children at home alone

    To determine risk factors for urinary tract infection (UTI) after urodynamic examination by evaluating patients' clinical characteristics and urodynamic parameters. Two hundred and sixty-one female patients (mean age 58.7 ± 12.3 years) from May to December 2011 who had lower urinary tract symptoms or needed definite diagnosis before pelvic floor reconstruction or anti-incontinence surgery received urodynamic examination. All patients received urinalysis on the scheduled day of urodynamic examination and 3 days after urodynamic examination. Mid-stream urine samples were obtained for urinalysis before urodynamic examination. If patients had UTI based on our urinalysis criteria before urodynamic examination, the investigation was postponed until the patient had a 3-7-day course of antibiotic treatment and urinalysis showed no UTI. Among 261 patients, 19 and 51 patients had UTI before and after urodynamic examination, respectively. Our data suggest that urodynamic examination causes significantly increased incidence of UTI. Increased number of vaginal births, UTI before investigation, diabetes and decreased average flow rate are risk factors for UTI after urodynamic examination. When the prevalence of UTI after urodynamic examination is higher than 10%, we recommend that prophylactic antibiotics should be given for high-risk patients with parameters such as older age, diabetes and multipara (>3). Those who have UTI before urodynamic examination and who are found to have a low average flow rate of less than 7 mL/second should take prophylactic antibiotics after examination. Copyright © 2013.

    The aims of this study were to investigate machine beam parameters using the TomoTherapy quality assurance (TQA) tool, establish a correlation to patient delivery quality assurance results and to evaluate the relationship between energy variations detected using different TQA modules. TQA daily measurement results from two treatment machines for periods of up to 4years were acquired. Analyses of beam quality, helical and static output variations were made. Variations from planned dose were also analysed using Statistical Process Control (SPC) technique and their relationship to output trends were studied. Energy variations appeared to be one of the contributing factors to delivery output dose seen in the analysis. Ion chamber measurements were reliable indicators of energy and output variations and were linear with patient dose verifications. Crown Copyright © 2017. Published by Elsevier Ltd.

    Nociceptive pain and its emotional component can result in the development of a "chronic pain memory". This report describes two patients who had long histories of chronic pain and opioid dependence. Both patients experienced sudden memory loss that was followed by significant pain reduction and an eradication of their need for opioid management. Neural centers involved in sensory pain, its affective component, opioid dependence, and memory overlap in the brain and share common pathways. The anterior cingulate cortex, the insular cortex, and the amygdala are examples of regions implicated in both pain and memory. One of the patients in the report experienced multiple seizure episodes, which may have contributed to memory loss and pain relief. The role of electroconvulsive therapy as it relates to amnesia and pain is reviewed. Questions are raised regarding whether therapies that address the memory component of pain may have a role in the treatment of long-term chronic pain patients.

    The purpose of this study is to investigate the effects of a relational intervention (the Getting Ready intervention) on parenting behaviors supporting the parent–infant relationship for families enrolled in Early Head Start home-based programming. Two-hundred thirty-four parents and their children participated in the randomized study, with 42% of parents reporting education of less than a high-school diploma. Brief, semistructured parent–child interaction tasks were videotaped every 4 months over a16-month intervention period. Observational codes of parent–infant relationship behaviors included quality of three parental behaviors: warmth and sensitivity, support for learning, and encouragement of autonomy; two appropriateness indicators: support for learning and guidance/directives; and one amount indicator: constructive behaviors. Parents who participated in the Getting Ready intervention demonstrated higher quality interactions with their children that included enhanced quality of warmth and sensitivity, and support for their children’s autonomy than did parents in the control group. They also were more likely to use appropriate directives with their children and more likely to demonstrate appropriate supports for their young children’s learning. Results indicate an added value of the Getting Ready intervention for Early Head Start home-based programming for families of infants and toddlers. PMID:24644374

    Essentials Literature on socioeconomic status (SES) and incidence of venous thromboembolism (VTE) is scarce. We assessed neighborhood SES with VTE risk in a population of over 1.4 million inhabitants. Higher neighborhood SES was associated with lower incidence of VTE. These findings are helpful to inform policy and resource allocation in health systems. Background The association between socioeconomic status and arterial cardiovascular disease is well established. However, despite its high burden of disability-adjusted life years, little research has been carried out to determine whether socioeconomic status is associated with venous thromboembolism. Objective To determine if neighborhood socioeconomic status is associated with venous thromboembolism in a population-based study from the Netherlands. Methods We identified all patients aged 15 years and older with a first event of venous thromboembolism from inhabitants who lived in the urban districts of The Hague, Leiden and Utrecht in the Netherlands in 2008-2012. Neighborhood socioeconomic status was based on the status score, which combines educational level, income and unemployment on a four-digit postal code level. Incidence rate ratios of venous thromboembolism were calculated for different levels of neighborhood socioeconomic status, with adjustments for age and sex. Results A total of 7373 patients with a first venous thromboembolism (median age 61 years; 50% deep vein thrombosis) were identified among more than 1.4 million inhabitants. Higher neighborhood SES was associated with lower incidence of VTE. In the two highest status score groups (i.e. the 95-99th and > 99th percentile), the adjusted incidence rate ratios were 0.91 (95% confidence interval [CI], 0.84-1.00) and 0.80 (95% CI, 0.69-0.93), respectively, compared with the reference status score group (i.e. 30-70th percentile). Conclusions High neighborhood socioeconomic status is associated with a lower risk of first venous thromboembolism. © 2017

    Strabismus in thyroid ophthalmopathy is based on a loss of the contractility and distensibility of the external ocular muscles. Different therapeutic approaches are available, such as recession after pre-. or intraoperative measurement, adjustable sutures, antagonist resection, or contralateral synergist faden-operation. 26 patients with strabismus in thyroid ophthalmopathy were operated between 2000 and 2003. All patients were examined preoperatively, then 1 day and 3 - 6 months (maximum 36 months) postoperatively. Before proceeding with surgery, we waited at least 6 months after stabilization of ocular alignment and normalization of thyroid chemistry. Preoperative vertical deviation was 10-44 PD (mean 22), 3 months postoperatively it was 2-10 PD (mean 1.5). Recession of the fibrotic muscle leads to reproducible results: 3.98 +/- 0.52 PD vertical deviation/mm for the inferior rectus. In the case of a large preoperative deviation a correction should be expected, which might not be sufficient in the first few days or weeks; a second operation should not be carried out before 3 months. 7 patients were operated twice, 1 patient need three operations. 4 patients (preop. 0) achieved no double vision at all; 15 patients (preop. 1) had no double vision in the primary and reading positions; 3 patients (preop. 0) had no double vision with a maximum of 5 PD; 1 patient (preop. 7) had double vision in the primary or reading position even with prisms; and 2 patients (preop. 17) had double vision in every position. We advocate that recession of the restricted inferior or internal rectus muscle is precise, safe and effective in patients with thyroid ophthalmopathy. The recessed muscle should be fixed directly at the sclera to avoid late over-correction through a slipped muscle. The success rate in terms of binocular single vision was 76 % and 88 % with prisms added.

    dialogue on admission more positively showed stronger treatment effects with respect to pain as well as to anxiety at discharge and six months after discharge. Analysis for single scales of the P.A.INT-Questionnaire revealed that this is due to affective and instrumental quality of the dialogues. Our results suggest a correlation between perceived interaction quality, as defined by our questionnaire and treatment effects six months after discharge. Comparisons of patient and physician evaluations showed that physicians seem to be successful in building relationships on the affective level, but less successful on the instrumental level (i.e. information, structuring and reinforcement). They also perceive disturbances on the relational and organisational level more strongly than patients. Our data underline the importance of interaction quality for the success of rehabilitation and thus the importance of specific skills such as providing and collecting information, recognizing patients' concerns and goals as well as reinforcement of health related action. Regular training and supervision should be provided to support physicians and to enhance their competence in dealing with patients concerns.

    Objective To examine the relationship between local food environments and obesity and assess the quality of studies reviewed. Methods Systematic keyword searches identified studies from US and Canada that assessed the relationship of obesity to local food environments. We applied a quality metric based on design, exposure and outcome measurement, and analysis. Results We identified 71 studies representing 65 cohorts. Overall, study quality was low; 60 studies were cross-sectional. Associations between food outlet availability and obesity were predominantly null. Among non-null associations, we saw a trend toward inverse associations between supermarket availability and obesity (22 negative, 4 positive, 67 null) and direct associations between fast food and obesity (29 positive, 6 negative, 71 null) in adults. We saw direct associations between fast food availability and obesity in lower income children (12 positive, 7 null). Indices including multiple food outlets were most consistently associated with obesity in adults (18 expected, 1 not expected, 17 null). Limiting to higher quality studies did not affect results. Conclusions Despite the large number of studies, we found limited evidence for associations between local food environments and obesity. The predominantly null associations should be interpreted cautiously due to the low quality of available studies. PMID:26096983

    If bioassessments are to help diagnose the specific environmental stressors affecting streams, a better understanding is needed of the relationships between community metrics and ambient criteria or ambient bioassays. However, this relationship is not simple, because metrics assess responses at the community level of biological organization, while ambient criteria and ambient bioassays assess or are based on responses at the individual level. For metals, the relationship is further complicated by the influence of other chemical variables, such as hardness, on their bioavailability and toxicity. In 1993 and 1994, U.S. Environmental Protection Agency (U.S. EPA) conducted a Regional Environmental Monitoring and Assessment Program (REMAP) survey on wadeable streams in Colorado's (USA) Southern Rockies Ecoregion. In this ecoregion, mining over the past century has resulted in metals contamination of streams. The surveys collected data on fish and macroinvertebrate assemblages, physical habitat, and sediment and water chemistry and toxicity. These data provide a framework for assessing diagnostic community metrics for specific environmental stressors. We characterized streams as metals-affected based on exceedence of hardness-adjusted criteria for cadmium, copper, lead, and zinc in water; on water toxicity tests (48-h Pimephales promelas and Ceriodaphnia dubia survival); on exceedence of sediment threshold effect levels (TELs); or on sediment toxicity tests (7-d Hyalella azteca survival and growth). Macroinvertebrate and fish metrics were compared among affected and unaffected sites to identify metrics sensitive to metals. Several macroinvertebrate metrics, particularly richness metrics, were less in affected streams, while other metrics were not. This is a function of the sensitivity of the individual metrics to metals effects. Fish metrics were less sensitive to metals because of the low diversity of fish in these streams.

    Adolescents with a strong tendency for irrational task delay (i.e., high trait procrastination) may be particularly prone to use Internet applications simultaneously to other tasks (e.g., during homework) and in an insufficiently controlled fashion. Both Internet multitasking and insufficiently controlled Internet usage may thus amplify the negative mental health implications that have frequently been associated with trait procrastination. The present study explored this role of Internet multitasking and insufficiently controlled Internet use for the relationship between trait procrastination and impaired psychological functioning in a community sample of N = 818 early and middle adolescents. Results from multiple regression analyses indicate that trait procrastination was positively related to Internet multitasking and insufficiently controlled Internet use. Insufficiently controlled Internet use, but not Internet multitasking, was found to partially statistically mediate the association between trait procrastination and adolescents' psychological functioning (i.e., stress, sleep quality, and relationship satisfaction with parents). The study underlines that adolescents with high levels of trait procrastination may have an increased risk for negative outcomes of insufficiently controlled Internet use.

    Background Globally, the high prevalence of overweight and low levels of physical activity among children has serious implications for morbidity and premature mortality in adulthood. Various parental factors are associated with childhood overweight and physical activity. The objective of this paper was to investigate relationships between parental education or overweight, and (i) child overweight, (ii) child physical activity, and (iii) explore household coexistence of overweight, in a large international sample. Methods Data were collected from 4752 children (9–11 years) as part of the International Study of Childhood Obesity, Lifestyle and the Environment in 12 countries around the world. Physical activity of participating children was assessed by accelerometry, and body weight directly measured. Questionnaires were used to collect parents’ education level, weight, and height. Results Maternal and paternal overweight were positively associated with child overweight. Higher household coexistence of parent-child overweight was observed among overweight children compared to the total sample. There was a positive relationship between maternal education and child overweight in Colombia 1.90 (1.23–2.94) [odds ratio (confidence interval)] and Kenya 4.80 (2.21–10.43), and a negative relationship between paternal education and child overweight in Brazil 0.55 (0.33–0.92) and the USA 0.54 (0.33–0.88). Maternal education was negatively associated with children meeting physical activity guidelines in Colombia 0.53 (0.33–0.85), Kenya 0.35 (0.19–0.63), and Portugal 0.54 (0.31–0.96). Conclusions Results are aligned with previous studies showing positive associations between parental and child overweight in all countries, and positive relationships between parental education and child overweight or negative associations between parental education and child physical activity in lower economic status countries.

    In this study, we explored the relationship between concealing emotions at work and musculoskeletal symptoms in Korean workers using data from a national, population-based survey. Data were obtained from the third Korean Working Conditions Survey in 2011. We investigated the prevalence of three musculoskeletal symptoms ("back pain", "pain in the upper extremities", and "pain in the lower extremities"). Multiple logistic regression analysis was also performed to determine odds ratios (ORs) for musculoskeletal symptoms according to concealing emotions at work, adjusting for socioeconomic factors. In both sexes, the emotion-concealing group showed a significantly higher prevalence of "pain in the upper extremities" and "pain in the lower extremities" than the non-emotion-concealing group. For back pain, male - but not female - workers who concealed their emotions showed a higher prevalence than their non-emotion-concealing counterparts; the difference was statistically significant. Adjusted ORs for musculoskeletal symptoms (excluding "back pain" for female workers) in the emotion-concealing group were significantly higher. Our study suggests that concealment of emotions is closely associated with musculoskeletal symptoms, and the work environment should operate in consideration not only of the physical health work condition of workers but also of their emotional efforts including concealing emotion at work.

    Trade shows is an increasingly important marketing activity to many companies, but current measures of trade show performance do not adequately capture dimensions important to exhibitors. Based on the marketing literature's outcome and behavior-based control system taxonomy, a model is built...... that captures a outcome-based sales dimension and four behavior-based dimensions (i.e. information-gathering, relationship building, image building, and motivation activities). A 16-item instrument is developed for assessing exhibitors perceptions of their trade show performance. The paper presents evidence...

    Full Text Available Objective: to develop a questionnaire for assessing the level of dentophobia and dynamics of the relationship in the «doctor-patient» in the course of treatment and to conduct its clinical trials. Material and Methods. 90 patients aged 26-56 years with chronic generalized periodontitis have been examined. The research has been conducted by Hospital Anxiety and depression (HADS questionnaire to determine the level of dentophobia; psychophysiological testing was carried out on the hardware-software complex (APC «NS-Psychotest» (LLC «Neurosoft», Russia, Ivanovo, 2007. Clinical examination included examination of the mouth and the index of assessment of hard tissue of teeth and peri-odontal tissue: a defining simplified oral hygiene index (UIG, sulcus bleeding index (IR, gingival index (PMA. The survey was carried out before the treatment and 3 months after the treatment. Statistical analysis was performed in the program Statistica. Using non-parametric methods (Wilcoxon test, criterion A2, Spearman correlation coefficient. Statistically significant differences with p < 0,05 were considered. Results. The development of the questionnaire was carried out in accordance with all generally accepted standards. The initial testing was performed easily by patients. During the clinical trials visible results of the proposed questionnaire were obtained that proved its sensitivity to the changes in dental and psychological status of the oral cavity. Conclusion. The practical application of the questionnaire determines the level of dentophobia during the first visit. The data of the questionnaire identify the differentiated deontological approach. It improves the relationship with the patient, reduces his level of dentophobia. The reduced dentophobia promotes compliance and psychologically comfortable communication in the doctor-patient system, which also contributes to the prevention of emotional burn out among dentists.

FM can be challenging to treat, and the treatment approach could benefit from a greater understanding of patients' perspectives on their condition and their care. Patients with FM participated in an online survey conducted in the USA that sought to identify the symptoms that had the greatest impact on patients' daily lives. The purpose of the survey was to facilitate efforts toward improving care of patients by nurse practitioners, primary care providers, and specialists, in addition to contributing to the development of new outcome measures in both clinical trials and general practice. A total of 1,228 patients with FM completed the survey, responding to specific questions pertaining to symptoms, impact of symptoms, management of FM, and the relationship with health care providers. Chronic pain was identified as the key FM symptom, affecting personal and professional relationships, and restricting physical activity, work, and social commitments. Patients felt that the severity of their condition was underestimated by family, friends, and health care providers. The results of this survey highlight the need for nurse practitioners, primary care providers, and specialists to provide understanding and support to patients as they work together to enable effective diagnosis and management of FM.

    Background: Health system performance is a multi-dimensional concept related to the achievement of several objectives such as effectiveness, efficiency and equity. The aim of this study is to investigate the relationship between models of health care systems (Beveridge, Bismarck and voluntary health insurance and performance frameworks available in the scientific literature.

    Methods: An extensive literature search in several electronic databases was carried out. According to a preliminary classification of performance domains and dimensions, we analysed, among the selected articles, the relationship between domains/dimensions and the three main models of health care systems.Results: 12.6% of the children were obese and 26.3% overweight, with the percentage of obesity nearly double in those who do not practice organized sports activities at least once a week, in those who don’t have breakfast in the morning and in those who don’t spend their free time in movement games. From a multiple logistic regression it results that the risk of being obese is twice and three times higher for the children living respectively in medium and small towns than for the ones living in large towns.

    Results: From 540 references found, 17 papers were considered relevant for the purposes of this research. A total of 39 frameworks were identified: 41% referred to the “Beveridge model, 10% to the “Bismarck model”, and 23% to the “Voluntary health insurance” model and 26% to “Umbrella organizations” (e.g. OECD. Domains of effectiveness and responsiveness were covered by all of the frameworks while fewer covered equity and efficiency. The most frequent dimensions in all the models were effectiveness and technical efficiency, but relevant differences exist among the healthcare system models about dimensions of performance considered.

  6. Is the Relationship Between Pornography Consumption Frequency and Lower Sexual Satisfaction Curvilinear? Results From England and Germany.

    Several studies using different methods have found that pornography consumption is associated with lower sexual satisfaction. The language used by media-effects scholars in discussions of this association implies an expectation that lowered satisfaction is primarily due to frequent-but not infrequent-consumption. Actual analyses, however, have assumed linearity. Linear analyses presuppose that for each increase in the frequency of pornography consumption there is a correspondingly equivalent decrease in sexual satisfaction. The present brief report explored the possibility that the association is curvilinear. Survey data from two studies of heterosexual adults, one conducted in England and the other in Germany, were employed. Results were parallel in each country and were not moderated by gender. Quadratic analysis indicated a curvilinear relationship, in the form of a predominantly negative, concave downward curve. Simple slope analyses suggested that when the frequency of consumption reaches once a month, sexual satisfaction begins to decrease, and that the magnitude of the decrease becomes larger with each increase in the frequency of consumption. The observational nature of the data employed precludes any causal inferences. However, if an effects perspective was adopted, these results would suggest that low rates of pornography consumption have no impact on sexual satisfaction and that adverse effects initiate only after consumption reaches a certain frequency.

    2013-01-01

    Objective: We evaluated the diagnostic role of ultrasonography-guided core needle biopsy (CNB) according to ultrasonography features of thyroid nodules that had inconclusive ultrasonography-guided fine-needle aspiration (FNA) results. Methods: A total of 88 thyroid nodules in 88 patients who underwent ultrasonography-guided CNB because of previous inconclusive FNA results were evaluated. The patients were classified into three groups based on ultrasonography findings: Group A, which was suspicious for papillary thyroid carcinoma (PTC); Group B, which was suspicious for follicular (Hurthle cell) neoplasm; and Group C, which was suspicious for lymphoma. The final diagnoses of the thyroid nodules were determined by surgical confirmation or follow-up after ultrasonography-guided CNB. Results: Of the 88 nodules, the malignant rate was 49.1% in Group A, 12.0% in Group B and 90.0% in Group C. The rates of conclusive ultrasonography-guided CNB results after previous incomplete ultrasonography-guided FNA results were 96.2% in Group A, 64.0% in Group B and 90.0% in Group C (p=0.001). 12 cases with inconclusive ultrasonography-guided CNB results were finally diagnosed as 8 benign lesions, 3 PTCs and 1 lymphoma. The number of previous ultrasonography-guided FNA biopsies was not significantly different between the conclusive and the inconclusive result groups of ultrasonography-guided CNB (p=0.205). Conclusion: Ultrasonography-guided CNB has benefit for the diagnosis of thyroid nodules with inconclusive ultrasonography-guided FNA results. However, it is still not helpful for the differential diagnosis in 36% of nodules that are suspicious for follicular neoplasm seen on ultrasonography. Advances in knowledge: This study shows the diagnostic contribution of ultrasonography-guided CNB as an alternative to repeat ultrasonography-guided FNA or surgery. PMID:23564885

    Obesity is an important disease with a high prevalence in cats. Because obesity is related to several other diseases, it is important to identify the population at risk. Several risk factors for obesity have been described in the literature. A higher incidence of obesity in certain cat breeds has been suggested. The aim of this study was to determine whether obesity occurs more often in certain breeds. The second aim was to relate the increased prevalence of obesity in certain breeds to the official standards of that breed. To this end, 268 cats of 22 different breeds investigated by determining their body condition score (BCS) on a nine-point scale by inspection and palpation, at two different cat shows. Overall, 45.5% of the show cats had a BCS > 5, and 4.5% of the show cats had a BCS > 7. There were significant differences between breeds, which could be related to the breed standards. Most overweight and obese cats were in the neutered group. It warrants firm discussions with breeders and cat show judges to come to different interpretations of the standards in order to prevent overweight conditions in certain breeds from being the standard of beauty. Neutering predisposes for obesity and requires early nutritional intervention to prevent obese conditions. Journal of Animal Physiology and Animal Nutrition © 2014 Blackwell Verlag GmbH.

    Previous research on organizational practices is replete with contradictory evidence regarding their effects. Here, the authors argue that these contradictory findings may have occurred because researchers have often examined complex practice combinations and have failed to investigate a broad variety of firm-level outcomes. Thus, past research may obscure important differential effects of specific practices on specific firm-level outcomes. Extending this research, the authors develop hypotheses about the effects of practices that (a) enable information sharing, (b) set boundaries, and (c) enable teams on 3 different firm-level outcomes: financial performance, customer service, and quality. Relationships are tested in a sample of observations from over 200 Fortune 1000 firms. Results indicate that information-sharing practices were positively related to financial performance 1 year following implementation of the practices, boundary-setting practices were positively related to firm-level customer service, and team-enabling practices were related to firm-level quality. No single set of practices predicted all 3 firm-level outcomes, indicating practice-specific effects. These findings help resolve the theoretical tension in the literature regarding the effects of organizational practices and offer guidance as to how to best target practices to increase specific work-related outcomes. Implications for theory, research, and practice are discussed. (c) 2007 APA

    While the literature on male sex work has increased significantly over the past decade, few studies examine the influence of relational dynamics in the lives of those engaged in male sex work. This qualitative study, conducted with a sample of male street sex workers in Sydney, Australia, explores how relationships color their involvement with sex work. The findings reveal the complexity of their relationships and how their interactions with others shape their engagement in sex work. The data also offer insight into how exit pathways are influenced by money and relationships that occur within this particular male sex work setting. Implications for health policy and intervention are considered.

    Sibling programming is an important part of a prevention framework, particularly for youth in foster care. After children are removed from their families and placed into foster care in the aftermath of maltreatment, the sibling relationship is often the most viable ongoing relationship available to the child, and may be critical to a youth's sense of connection, emotional support, and continuity. The promise of dyadic sibling programming in particular rests on the ability of interventions to enhance the quality of sibling relationships; yet little research exists that suggests that sibling interventions can improve relationship quality among foster youth. The primary aim of the current study was to examine the effects of a specific dyadic sibling-focused intervention for older and younger siblings on sibling relationship quality. One hundred sixty four dyads (328 youth) participated in the study, with each dyad consisting of an older sibling between 11 and 15 years of age at baseline and a younger sibling separated in age by less than 4 years. Hierarchical linear models were applied to self-reported, observer-reported and observational data over the 18-month study period. Findings suggest that the sibling intervention holds promise for improving sibling relationship quality among youth in foster care. Implications and future directions for research are discussed.

    Performance of different organizations, such as hospitals is mainly influenced by their managers’ performance. Nursing managers have an important role in hospital performance and their managerial skills can improve the quality of the services. Hence, the present study was conducted in order to assess the relationship between the managerial skills and the results of their performance evaluation in Teaching Hospitals of Iran University of Medical Science in 2013. The research used the cross sectional method in 2013. It was done by distributing a managerial skills assessment questionnaire, with close-ended questions in 5 choice Likert scale, among 181 managers and head nurses of hospitals of Iran university of Medical Sciences; among which 131 answered the questions. Another data collection tools was a forms to record evaluation marks from the personnel records. We used Pearson and Spearman correlation tests and SPSS for analysis and description (frequency, mean and standard deviation). Results showed that the managerial skills of the nursing mangers were fair (2.57 out of 5) and the results of the performance evaluation were in a good condition (98.44). The mangers’ evaluation results and the managerial skills scores were not in a meaningful correlation (r=0.047 np=0.856). The research showed no correlation between different domains of managerial skills and the performance evaluation marks: decision making skills (r=0.074 and p=0.399), leadership (correlation coefficient 0.028 and p=0.654), motivation (correlation coefficient 0.118 and p=0.163), communication (correlation coefficient 0.116 and p=0.122), systematic thinking (correlation coefficient 0.028 and p=0.828), time management (correlation coefficient 0.077 and p=0.401) and strategic thinking (correlation coefficient 0.041 and p=0.756). Lack of any correlation and relation between managers’ managerial skills and their performance evaluation results shows need to a fundamental revision at managers

    This study's aims were to describe the development of physical activity, physical fitness (PF), subjective (physical complaints (PC)) and objective (Body mass index (BMI)) health measures and to examine the relationship between the development trajectories. In addition, the study also aimed to assess the influence of sociodemographic determinants (age, sex, socioeconomic status (SES)) in German adults over a period of 18 years. The longitudinal study population comprises of 721 men and women, aged 33-76 years over the study period. There was self-report of physical activity and PC and testing of physical fitness and BMI in each study year (1992, 1997, 2002 and 2010). Latent growth curve models were used to analyse the development. Physical activity slightly increased while fitness, PC and BMI worsened over the course of 18 years. Sex, age and SES play important roles concerning physical activity, fitness and health. Several integrative associations could be detected between physical activity, fitness, PC and BMI as well as their trajectories. In particular, high initial levels of physical activity and fitness protect from high PC and BMI.The slope of physical activity was not significantly associated with slopes of fitness, PC and BMI. However, increase of fitness resulted in decrease of PC. A general positive development regarding the amount of physical activity could be detected. However, if it is only an unsystematic increase of physical activity, this is not in itself enough to achieve health benefits. The strengthening of fitness should be focused when increasing physical activity, since only then a health benefit is possible.

This systematic literature review explored the relationship between the hospitalization rates and the COPD comorbidities, anxiety, and depression.Methods: The Centre for Research Dissemination's framework for systematic reviews was followed using search terms relating to COPD, anxiety, depression, and hospital admission. Papers identified were assessed for relevance and quality, using a suitable Critical Appraisal Skills Programme tool and Mixed Methods Assessment Tool.Results: Twenty quantitative studies indicated that anxiety and depression led to a statistically significant increase in the likelihood of COPD patients being hospitalized. These comorbidities also led to an increased length of stay and a greater risk of mortality postdischarge. Other significant factors included lower Body-Mass Index, Airflow Obstruction, Dyspnea, and Exercise scores, female gender, lower socioeconomic status, poorer patient perceived quality of life, increased severity of lung function, and less improvement in dyspnea from admission to discharge. It was also highlighted that only 27%–33% of those with depression were being treated for it. Four qualitative studies revealed that patients saw anxiety and depression as a major factor that affected their ability to cope with and self-manage their condition.Implications: Findings from the systematic review have highlighted a need for better recognition and treatment of anxiety and depression amongst individuals with COPD. Ongoing research will develop and test strategies for promoting better management

    The Relationship of Indoor, Outdoor and Personal Air (RIOPA) Study was undertaken to evaluate the contribution of outdoor sources of air toxics, as defined in the 1990 Clean Air Act Amendments, to indoor concentrations and personal exposures. The concentrations of 18 volatile organic compounds (VOCs), 17 carbonyl compounds, and fine particulate matter mass (PM(2.5)) were measured using 48-h outdoor, indoor and personal air samples collected simultaneously. PM2.5 mass, as well as several component species (elemental carbon, organic carbon, polyaromatic hydrocarbons and elemental analysis) were also measured; only PM(2.5) mass is reported here. Questionnaires were administered to characterize homes, neighborhoods and personal activities that might affect exposures. The air exchange rate was also measured in each home. Homes in close proximity (<0.5 km) to sources of air toxics were preferentially (2:1) selected for sampling. Approximately 100 non-smoking households in each of Elizabeth, NJ, Houston, TX, and Los Angeles, CA were sampled (100, 105, and 105 respectively) with second visits performed at 84, 93, and 81 homes in each city, respectively. VOC samples were collected at all homes, carbonyls at 90% and PM(2.5) at 60% of the homes. Personal samples were collected from nonsmoking adults and a portion of children living in the target homes. This manuscript provides the RIOPA study design and quality control and assurance data. The results from the RIOPA study can potentially provide information on the influence of ambient sources on indoor air concentrations and exposure for many air toxics and will furnish an opportunity to evaluate exposure models for these compounds.

    The aim of this study was to investigate the relationship between markers of body fat and bone status assessed as calcaneal bone stiffness in a large sample of European healthy pre- and primary school children. Participants were 7,447 children from the IDEFICS study (spread over eight different European countries), age 6.1 ± 1.8 years (range 2.1-9.9), 50.5 % boys. Anthropometric measurements (weight, height, bioelectrical impedance, waist and hip circumference, and tricipital and subscapular skinfold thickness) as well as quantitative ultrasonographic measurements to determine calcaneal stiffness index (SI) were performed. Partial correlation analysis, linear regression analysis, and ANCOVA were stratified by sex and age group: preschool boys (n = 1,699) and girls (n = 1,599) and primary school boys (n = 2,062) and girls (n = 2,087). In the overall study population, the average calcaneal SI was equal to 80.2 ± 14.0, ranging 42.4-153. The results showed that preschool children with higher body fat had lower calcaneal SI (significant correlation coefficients between -0.05 and -0.20), while primary school children with higher body fat had higher calcaneal SI (significant correlation coefficients between 0.05 and 0.13). After adjusting for fat-free mass, both preschool and primary school children showed an inverse relationship between body fat and calcaneal stiffness. To conclude, body fat is negatively associated with calcaneal bone stiffness in children after adjustment for fat-free mass. Fat-free mass may confound the association in primary school children but not in preschool children. Muscle mass may therefore be an important determinant of bone stiffness.

    Full Text Available Aim: Neutrophil/lymphocyte ratio (NLR and platelet/lymphocyte ratio (PLR are used as inflammatory markers in several diseases. However, there are little data regarding the diagnostic ability of NLR and PLR in Helicobacter pylori. We aimed to assess the association between the 14C urea breath test (14C-UBT results and NLR and PLR in H. pylori diagnosis. Methods: Results of 89 patients were retrospectively analysed in this study. According to the 14C-UBT results, patients were divided into two groups: H. pylori (+ and H. pylori (- (control group. Haematological parameters, including hemoglobine, white blood cell (WBC count, neutrophil count, lymphocyte count, NLR, platelet count, and PLR were compared between the two groups. Results: The mean total WBC count, neutrophil count, NLR and PLR in H. pylori (+ patients were significantly higher than in the control group (p<0.001 for all these parameters. In the receiver operating characteristic curve analysis, the cut-off value for NLR and PLR for the presence of H. pylori was calculated as ≥2.39 [sensitivity: 67.3%, specificity: 79.4%, area under the curve (AUC: 0.747 (0.637-0.856, p<0.0001] and ≥133.3 [sensitivity: 61.8%, specificity: 55.9%, AUC: 0.572 (0.447-0.697, p<0.05], respectively. Conclusion: The present study shows that NLR and PLR are associated with H. pylori positivity based on 14C-UBT, and they can be used as an additional biomarker for supporting the 14C-UBT results.

    Full Text Available This paper reports an exploration into Indonesian fourth graders’ difficulties in fractions and their relation to the opportunity to learn fractions students got at schools. The concept of ‘opportunity to learn’ is often considered as a framework to investigate possible reasons for students’ difficulties. The data for this study was drawn from TIMSS 2015 that comprised test results and teachers’ responses to TIMSS Teacher Questionnaire. The test and questionnaire data were analysed by using descriptive statistics. In addition to test and questionnaire, this study also included an analysis of Indonesian textbooks in order to get a broader scope of the opportunity to learn. Qualitative approach was used to analyse the textbooks. The analysis of the TIMSS results shows Indonesian students’ low conceptual understanding of fractions. Three possible reasons for students’ low conceptual understanding were revealed. First, the content of Indonesian curriculum that gave low emphasis on basic concepts of fractions and introduced operations of fractions too early. Second, the Indonesian mathematics textbooks only presented one definition of fractions, i.e. fractions as parts of wholes. Third, there is a limited use of models or representations of fractions in the classroom practices.

    To provide a foundation for those who provide sexual health services and programs to men in the United States, the need for population-based data that describes men's sexual behaviors and their correlates remains. The purpose of this study was to, in a national probability survey of men ages 18-94 years, assess the occurrence and frequency of sexual behaviors and their associations with relationship status and health status. A national probability sample of 2,522 men aged 18 to 94 completed a cross-sectional survey about their sexual behaviors, relationship status, and health. Relationship status; health status; experience of solo masturbation, partnered masturbation, giving oral sex, receiving oral sex, vaginal intercourse and anal intercourse, in the past 90 days; frequency of solo masturbation, vaginal intercourse and anal intercourse in the past year. Masturbation, oral intercourse, and vaginal intercourse are prevalent among men throughout most of their adult life, with both occurrence and frequency varying with age and as functions of relationship type and physical health status. Masturbation is prevalent and frequent across various stages of life and for both those with and without a relational partner, with fewer men with fair to poor health reporting recent masturbation. Patterns of giving oral sex to a female partner were similar to those for receiving oral sex. Vaginal intercourse in the past 90 days was more prevalent among men in their late 20s and 30s than in the other age groups, although being reported by approximately 50% of men in the sixth and seventh decades of life. Anal intercourse and sexual interactions with other men were less common than all other sexual behaviors. Contemporary men in the United States engage in diverse solo and partnered sexual activities; however, sexual behavior is less common and more infrequent among older age cohorts. © 2010 International Society for Sexual Medicine.

    This study aimed to gain more insight into young Rwandans' perceptions on sex and relationships, which is essential for formulating effective sexual and reproductive health (SRH) promotion interventions. Using a 'mailbox technique', this paper studies the spontaneous thoughts of Rwandan young people on sexuality. Mailboxes were installed in five secondary schools in the Bugesera district and students were invited to write about their ideas, secrets, wishes, desires and fears on sexuality and relationships. Of the 186 letters collected, 154 addressed SRH topics. The letters were analysed in NVivo 9 using a theoretical model on vulnerability. Two stereotypical sexual interactions co-exist: experimental sex, taking place unprepared, driven by desire among young people of the same age, and transactional sex, occurring after negotiation between older men/women and younger girls/boys in exchange for money or goods. Both types expose young people to poor, though different, SRH outcomes. Young people have little capacity to manage their vulnerability in these relationships: they have limited knowledge on SRH topics, lack adult guidance or support and have difficult access to condoms. They apply seemingly contradictory norms and behaviours concerning sexuality. In conclusion, we have formulated several recommendations for SRH interventions.

    The aim of this study was to investigate whether adopting healthy lifestyle habits, such as engaging in leisure time physical activity (LTPA), adopting recommended dietary patterns, and not smoking, are associated with reduced hospitalizations over 1 year among adults with diabetes. We analyzed data from a national sample of people aged 18 years and above with self-reported physician-diagnosed diabetes (n = 664) through linkage to the 2001 National Health Interview Survey in Taiwan and the 2002 National Health Insurance claims data. Multivariate analysis showed that participants reporting greater than 150 min/wk of moderate-intensity activity had a significantly lower chance for hospitalization (odds ratio = 0.52; 95% confidence interval [CI] = 0.27-0.98), fewer admissions (incidence rate ratio [IRR] = 0.58; 95% CI = 0.33-1.00), and fewer hospital bed days (IRR = 0.42; 95% CI = 0.20-0.92) compared with inactive individuals. Diet control and smoking status did not significantly predict hospital use after controlling for other factors. Our findings indicate that increased LTPA results in reduced hospitalization among adults with diabetes. © 2014 APJPH.

    Recent studies have reported an association between periodontal disease and mortality among dialysis patients. Therefore, preventive dental care should be considered very important for this population. In Japan, no systematic education has been undertaken regarding the importance of preventive dental care for hemodialysis patients--even though these individuals tend to have oral and dental problems. The aim of this study was to investigate the current state of collaborative relationships between hemodialysis facilities and dental services in Japan and also to identify strategies to encourage preventive dental visits among hemodialysis outpatients. A nationwide questionnaire on the collaborative relationship between dialysis facilities and dental facilities was sent by mail to all medical facilities in Japan offering outpatient hemodialysis treatment. Responses were obtained from 1414 of 4014 facilities (35.2%). Among the 1414 facilities, 272 (19.2%) had a dental service department. Approximately 100,000 dialysis outpatients were receiving treatment at these participating facilities, which amounts to one-third of all dialysis patients in Japan. Of those patients, 82.9% received hemodialysis at medical facilities without dental departments. Only 87 of 454 small clinics without in-house dental departments (19.2%) had collaborative registered dental clinics. Medical facilities with registered dental clinics demonstrated a significantly more proactive attitude to routine collaboration on dental matters than facilities lacking such clinics. Our nationwide survey revealed that most dialysis facilities in Japan have neither an in-house dental department nor a collaborative relationship with a registered dental clinic. Registration of dental clinics appears to promote collaboration with dental facilities on a routine basis, which would be beneficial for oral health management in hemodialysis patients.

    Past surveys of sexual behavior have demonstrated that female sexual behavior is influenced by medical and sociocultural changes. To be most attentive to women and their sexual lives, it is important to have an understanding of the continually evolving sexual behaviors of contemporary women in the United States. The purpose of this study, the National Survey of Sexual Health and Behavior (NSSHB), was to, in a national probability survey of women ages 18-92, assess the proportion of women in various age cohorts who had engaged in solo and partnered sexual activities in the past 90 days and to explore associations with participants' sexual behavior and their relationship and perceived health status. Past year frequencies of masturbation, vaginal intercourse, and anal intercourse were also assessed. A national probability sample of 2,523 women ages 18 to 92 completed a cross-sectional internet based survey about their sexual behavior. Relationship status; perceived health status; experience of solo masturbation, partnered masturbation, giving oral sex, receiving oral sex, vaginal intercourse, anal intercourse, in the past 90 days; frequency of solo masturbation, vaginal intercourse, and anal intercourse in the past year. Recent solo masturbation, oral sex, and vaginal intercourse were prevalent among women, decreased with age, and varied in their associations with relationship and perceived health status. Recent anal sex and same-sex oral sex were uncommonly reported. Solo masturbation was most frequent among women ages 18 to 39, vaginal intercourse was most frequent among women ages 18 to 29 and anal sex was infrequently reported. Contemporary women in the United States engage in a diverse range of solo and partnered sexual activities, though sexual behavior is less common and more infrequent among older age cohorts. © 2010 International Society for Sexual Medicine.

    Performance of different organizations, such as hospitals is mainly influenced by their managers' performance. Nursing managers have an important role in hospital performance and their managerial skills can improve the quality of the services. Hence, the present study was conducted in order to assess the relationship between the managerial skills and the results of their performance evaluation in Teaching Hospitals of Iran University of Medical Science in 2013. The research used the cross sectional method in 2013. It was done by distributing a managerial skills assessment questionnaire, with close-ended questions in 5 choice Likert scale, among 181 managers and head nurses of hospitals of Iran university of Medical Sciences; among which 131 answered the questions. Another data collection tools was a forms to record evaluation marks from the personnel records. We used Pearson and Spearman correlation tests and SPSS for analysis and description (frequency, mean and standard deviation). Results showed that the managerial skills of the nursing mangers were fair (2.57 out of 5) and the results of the performance evaluation were in a good condition (98.44). The mangers' evaluation results and the managerial skills scores were not in a meaningful correlation (r=0.047 np=0.856). The research showed no correlation between different domains of managerial skills and the performance evaluation marks: decision making skills (r=0.074 and p=0.399), leadership (correlation coefficient 0.028 and p=0.654), motivation (correlation coefficient 0.118 and p=0.163), communication  (correlation coefficient 0.116 and p=0.122), systematic thinking  (correlation coefficient 0.028 and p=0.828), time management (correlation coefficient 0.077 and p=0.401) and strategic thinking  (correlation coefficient 0.041 and p=0.756). Lack of any correlation and relation between managers' managerial skills and their performance evaluation results shows need to a fundamental revision at managers

    Health literacy has been put forward as a potential mechanism explaining the well-documented relationship between education and health. However, little empirical research has been undertaken to explore this hypothesis. The present study aims to study whether health literacy could be a pathway by which level of education affects health status. Health literacy was measured by the Health Activities and Literacy Scale, using data from a subsample of 5,136 adults between the ages of 25 and 65 years, gathered within the context of the 2007 Dutch Adult Literacy and Life Skills Survey. Linear regression analyses were used in separate models to estimate the extent to which health literacy mediates educational disparities in self-reported general health, physical health status, and mental health status as measured by the Short Form-12. Health literacy was found to partially mediate the association between low education and low self-reported health status. As such, improving health literacy may be a useful strategy for reducing disparities in health related to education, as health literacy appears to play a role in explaining the underlying mechanism driving the relationship between low level of education and poor health.

    Three hundred and fifty randomly selected primary school children completed a psychometric and psychophysical test battery to ascertain relationships between reading ability and sensitivity to dynamic visual and auditory stimuli. The first analysis examined whether sensitivity to visual coherent motion and auditory frequency resolution differed between groups of children with different literacy and cognitive skills. For both tasks, a main effect of literacy group was found in the absence of a main effect for intelligence or an interaction between these factors. To assess the potential confounding effects of attention, a second analysis of the frequency discrimination data was conducted with performance on catch trials entered as a covariate. Significant effects for both the covariate and literacy skill was found, but again there was no main effect of intelligence, nor was there an interaction between intelligence and literacy skill. Regression analyses were conducted to determine the magnitude of the relationship between sensory and literacy skills in the entire sample. Both visual motion sensitivity and auditory sensitivity to frequency differences were robust predictors of children's literacy skills and their orthographic and phonological skills.

    Systemic sclerosis (SSc; scleroderma) is associated with a wide periodontal ligament (PDL) and mandibular erosions. We investigated the clinical correlates of SSc with these radiologic abnormalities. Subjects from the Canadian Scleroderma Research Group cohort underwent detailed radiologic examinations. Associations between radiologic abnormalities and clinical manifestations of SSc were examined with univariate and multivariate analyses. The study included 159 subjects; 90.6% were women, the mean ± SD age was 56 ± 10 years, diffuse disease was present in 28.3%, and mean ± SD disease duration was 13.7 ± 8.4 years. Widening of the PDL involving at least 1 tooth was present in 38% of subjects, and 14.5% had at least 1 site in the mandible with an erosion. In analyses adjusting for age, disease duration, sex, smoking, and education, we found significant associations between the number of teeth with widening of the PDL and disease severity assessed by the physician global assessment (PGA) (relative risk [RR] 1.19, 95% confidence interval [95% CI] 1.02-1.39, P = 0.028). Analyses replacing the PGA with the skin score, disease subset, or anti-topoisomerase I antibodies confirmed the relationship with indices of disease severity. There was no relationship between either the number of teeth with periodontal disease or the number of missing teeth, and the number of teeth with wide PDL. A smaller interdental distance (RR 0.89, 95% CI 0.82-0.97, P = 0.006), but not disease severity, facial skin score, or ischemia was associated with a larger number of erosions. In SSc, a wide PDL may reflect generalized overproduction of collagen, and mandibular erosions are related to local factors in the oral cavity. © 2016, American College of Rheumatology.

    To investigate the relationship between musculoskeletal disorders and comorbid health problems, including depression/anxiety disorder, insomnia/sleep disorder, fatigue, and injury by accident, and to determine whether certain physical and psychological factors reduce comorbid health problems. In total, 29,711 employees were selected from respondents of the Third Korean Working Conditions Survey and categorized into two groups: Musculoskeletal Complaints or Musculoskeletal Sickness Absence. Four self-reported health indicators (overall fatigue, depression/anxiety, insomnia/sleep disorder, and injury by accident) were selected as outcomes, based on their high prevalence in Korea. We used multiple logistic regression analysis to determine the relationship between comorbid health problems, musculoskeletal complaints, and sickness absence. The prevalence of musculoskeletal complaints and musculoskeletal sickness absence due to muscular pain was 32.26% and 0.59%, respectively. Compared to the reference group, depression/anxiety disorder and overall fatigue were 5.2-6.1 times more prevalent in the Musculoskeletal Complaints Group and insomnia/sleep disorder and injury by accident were 7.6-11.0 times more prevalent in the Sickness Absence Group. When adjusted for individual and work-related physical factors, prevalence of all four comorbid health problems were slightly decreased in both groups. Increases in overall fatigue and depression/anxiety disorder were observed in the Musculoskeletal Complaints Group, while increases in insomnia/sleep disorder and injury by accident were observed in the Sickness Absence Group. For management of musculoskeletal complaints and sickness absence in the workplace, differences in health problems between employees with musculoskeletal complaints and those with sickness absence as well as the physical and psychological risk factors should be considered.

    One year ago, we reported the results of a 2008 Zogby survey that purported to gauge economic enlightenment (Buturovic and Klein 2010). Our main result was that college education bore little relationship to economic enlightenment. We also found that that self-identified Progressives and Liberals did much worse than Conservatives and Libertarians, and this finding generated a lot of controversy. Those results were based on eight questions used to gauge economic enlightenment. Most of those eig...

    Haemostatic and inflammatory markers have been hypothesised to mediate the relationship of social class and cardiovascular disease (CVD). We investigated whether a range of inflammatory/haemostatic markers are associated with social class independent of chronic diseases and behavioural risk factors in a population-based sample of 2682 British men aged 60-79 without a physician diagnosis of CVD, diabetes or musculoskeletal disease requiring anti-inflammatory medications. Men in lower social classes had higher mean levels of C-reactive protein, fibrinogen, interleukin-6, white blood cell count, von Willebrand factor (vWF), factor VIII, activated protein C (APC) resistance, plasma viscosity, fibrin D-dimer and platelet count, compared to higher social class groups; but not of tissue plasminogen activator antigen, haematocrit or activated partial prothrombin time. After adjustment for behavioural risk factors (smoking, alcohol, physical activity and body mass), the associations of social class with vWF, factor VIII, APC resistance, plasma viscosity, and platelet count though weakened, remained statistically significant, while those of other markers were considerably attenuated. In this study of older men without CVD, the social gradient in inflammatory and haemostatic markers was substantially explained by behavioural risk factors. The effect of socio-economic gradient on the factor VIII-vWF complex, APC resistance, plasma viscosity and platelet count merits further study.

    Whether the severity of left main coronary artery (LMCA) disease reflects LMCA and overall coronary atherosclerotic burden is not known. We aimed to assess nonculprit LMCA disease characteristics and the relationship with atherosclerosis in the rest of the coronary arteries as well as patient outcomes. In the PROSPECT study, 697 patients with acute coronary syndromes underwent three-vessel gray-scale and radiofrequency intravascular ultrasound after percutaneous coronary intervention. Overall, 552 patients with adequate LMCA imaging were compared according to LMCA plaque burden. The tertile with the highest plaque burden in the LMCA had the smallest LMCA minimum lumen area (17.4, 14.2, 10.5, lowest through highest tertiles, respectively, PPROSPECT predictors of future nonculprit major adverse cardiac events (MACE) (minimum lumen area≤4 mm, plaque burden≥70%, and virtual histology thin-cap fibroatheroma), the tertile with the highest LMCA plaque burden had the highest number of patients with at least one of three PROSPECT predictors (P=0.03). In multivariable model, though total atheroma volume (per 1%) was an independent predictor of all MACE [hazard ratio (95% confidence interval)=1.06 (1.01-1.11), P=0.02] and strong trend for non-culprit-related MACE [hazard ratio (95% confidence interval)=1.06 (1.00-1.13), P=0.06], plaque burden at LMCA was not (all MACE, P=0.90, non-culprit-related MACE, P=0.85). The severity of atherosclerosis in LMCA predicted the overall atherosclerotic plaque burden as well as the presence of high-risk plaques in the three major epicardial coronary arteries.

    We aimed to examine the potential relationship between season of birth (SOB) and clinical characteristics in Korean patients with unipolar non-psychotic major depressive disorder (MDD). Using data from the Clinical Research Center for Depression (CRESCEND) study in South Korea, 891 MDD patients were divided into two groups, those born in spring/summer (n=457) and those born in autumn/winter (n=434). Measurement tools comprising the Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, Brief Psychiatric Rating Scale, Scale for Suicidal Ideation, Clinical Global Impression of severity, Social and Occupation Functional Assessment Scale, WHO Quality of Life assessment instrument-abbreviated version, Alcohol Use Disorder Identification Test, and Temperament and Character Inventory were used to evaluate depression, anxiety, overall symptoms, suicidal ideation, global severity, social function, quality of life, drinking, and temperament and character, respectively. Using independent t-tests for continuous variables and χ² tests for discrete variables, the clinical characteristics of the two groups were compared. MDD patients born in spring/summer were on average younger at onset of first depressive episode (t=2.084, p=0.038), had greater loss of concentration (χ²=4.589, p=0.032), and were more self-directed (t=2.256, p=0.025) than those born in autumn/winter. Clinically, there was a trend for the MDD patients born in spring/summer to display the contradictory characteristics of more severe clinical course and less illness burden; this may have been partly due to a paradoxical effect of the 5-HT system.

    Schizophrenia is a chronic disease that requires long-term management with antipsychotics. Antipsychotic drugs are given by tapering their dose, extending the dosing interval, and so on, as part of a treatment strategy to minimize the adverse effects while at the same time maintaining efficacy. We report the case of one patient with schizophrenia in whom the clinical symptoms were alleviated after treatment with 6 mg paliperidone. However, the patient developed extrapyramidal syndrome, for which 3 and 6 mg paliperidone were administered alternately every other day. Extrapyramidal syndrome was assessed using the Drug-Induced Extrapyramidal Symptoms Scale, Abnormal Involuntary Movement Scale, or Barnes Akathisia Scale. There was improvement in Drug-Induced Extrapyramidal Symptoms Scale score and Abnormal Involuntary Movement Scale score. However, there was almost no change in the Positive and Negative Syndrome Scale total score, positive score, negative score, or general score. The results indicate the possibility of lessened adverse effects as a result of an alternative regimen of treatment with paliperidone 3 and 6 mg every other day in the maintenance phase.

    Full Text Available The application of the neoliberal concept in the Western Balkans has had effects on the economies of those countries that can say das resulted in unsustainable economic growth and macroeconomic instability. Besides the application of the same given the developments that had features of weakness especially since 2008., from the onset of the global economic crisis. The consequences of the liberalization of international economic developments have enabled the countries of the Western Balkans obtain foreign investment in the form of foreign direct investment, but their economies have done even more dependent on foreign capital, which is increasingly going in economic activities that have a faster way could fertilize the invested capital.

    Medication errors are a significant cause of morbidity and mortality especially with antineoplastic drugs, owing to their narrow therapeutic index. Gravimetric workflow software systems have the potential to reduce volumetric errors during intravenous antineoplastic drug preparation which may occur when verification is reliant on visual inspection. Our aim was to detect medication errors with possible critical therapeutic impact as determined by the rate of prevented medication errors in chemotherapy compounding after implementation of gravimetric measurement. A large-scale, retrospective analysis of data was carried out, related to medication errors identified during preparation of antineoplastic drugs in 10 pharmacy services ("centres") in five European countries following the introduction of an intravenous workflow software gravimetric system. Errors were defined as errors in dose volumes outside tolerance levels, identified during weighing stages of preparation of chemotherapy solutions which would not otherwise have been detected by conventional visual inspection. The gravimetric system detected that 7.89% of the 759 060 doses of antineoplastic drugs prepared at participating centres between July 2011 and October 2015 had error levels outside the accepted tolerance range set by individual centres, and prevented these doses from reaching patients. The proportion of antineoplastic preparations with deviations >10% ranged from 0.49% to 5.04% across sites, with a mean of 2.25%. The proportion of preparations with deviations >20% ranged from 0.21% to 1.27% across sites, with a mean of 0.71%. There was considerable variation in error levels for different antineoplastic agents. Introduction of a gravimetric preparation system for antineoplastic agents detected and prevented dosing errors which would not have been recognized with traditional methods and could have resulted in toxicity or suboptimal therapeutic outcomes for patients undergoing anticancer treatment.

    Immunoglobulin light chain (AL) amyloidosis is a rare plasma cell dyscrasia characterized by the deposition of abnormal amyloid fibrils in multiple organs, thus impairing their function. In the largest cohort studied up to now of 118 CD138-purified plasma cell samples from previously untreated immunoglobulin light chain amyloidosis patients, we assessed in parallel copy number alterations using high-density copy number arrays and interphase fluorescence in situ hybridization (iFISH). We used fluorescence in situ hybridization probes for the IgH translocations t(11;14), t(4;14), and t(14;16) or any other IgH rearrangement as well as numerical aberrations of the chromosome loci 1q21, 8p21, 5p15/5q35, 11q22.3 or 11q23, 13q14, 15q22, 17p13, and 19q13. Recurrent gains included chromosomes 1q (36%), 9 (24%), 11q (24%), as well as 19 (15%). Recurrent losses affected chromosome 13 (29% monosomy) and partial losses of 14q (19%), 16q (14%) and 13q (12%), respectively. In 88% of patients with translocation t(11;14), the hallmark chromosomal aberration in AL amyloidosis, a concomitant gain of 11q22.3/11q23 detected by iFISH was part of the unbalanced translocation der(14)t(11;14)(q13;q32) with the breakpoint in the CCND1/MYEOV gene region. Partial loss of chromosome regions 14q and 16q were significantly associated to gain 1q. Gain 1q21 detected by iFISH almost always resulted from a gain of the long arm of chromosome 1 and not from trisomy 1, whereas deletions on chromosome 1p were rarely found. Overall and event-free survival analysis found a potential adverse prognostic effect of concomitant gain 1q and deletion 14q as well as of deletion 1p. In conclusion, in the first whole genome report of clonal plasma cells in AL amyloidosis, novel aberrations and hitherto unknown potential adverse prognostic effects were uncovered.

    The authors measured the radioactivity in the soil and child food samples from farms near Mogilev (56--270 GBq km -2 137 Cs), Gomel (36--810 GBq km -2 137 Cs), and Klincy (59--270 GBq km -2 137 Cs), who had whole-body 137 Cs counting results measured as part of a health examination in the Chernobyl Sasakawa Health and Medical Cooperation Project. Soil contamination on the family farm seems to be the main source of human contamination because most of the people in the area live on small farms and they and their domestic animals eat crops from the farms. A clear correlation was found between the children's whole-body 137 Cs counting results and the radioactivity in their food (correlation coefficient: 0.76; confidence level of correlation: 3.2 x 10 -9 ). There were also significant correlations between the whole-body 137 Cs counting results and both the radioactivity of the soil samples (correlation coefficient: 0.22; confidence level of correlation: 0.0107) and the average contamination level of their current residence (correlation coefficient: 0.20; confidence level of correlation: 0.0174)

    Full Text Available Physical activity as a part of the lifestyle is a significant factor influencing health condition. Exercises that require stamina are of particular importance. Oxygen metabolism, which is a significant part of all longer training processes, has an influence on cardiovascular and respiratory system functioning as well as all the processes taking part in maintenance of efficient homeostasis. Presentation of the correlation between exercise test results and MMP-8 (metalloproteinase-8 and TIMP-1 (tissue inhibitor of metalloproteinases-1 levels was attempted in this work. MMP-8 is a proteolytic enzyme taking part in progression of diseases related to process of ageing. 62 healthy women in postmenopausal period were qualified for the study (mean age: 54±3.6. There was exercise test on the treadmill according to Bruce’s protocol performed. MMP-8 and TIMP-1 serum levels were measured. There was statistically important correlation between increased level of MMP-8 and increased level of TIMP-1 with lower results of exercise test observed. The conducted study provides further biochemical arguments for prophylactic role of physical activity, which lowers the risk of noninfectious diseases, typical for middle adulthood, by influencing physical capacity.

    2015-01-01

    Full Text Available Background: Complex noise and its relation to hearing loss are difficult to measure and evaluate. In complex noise measurement, individual exposure results may not accurately represent lifetime noise exposure. Thus, the mean L Aeq,8 h values of individuals in the same workgroup were also used to represent L Aeq,8 h in our study. Our study aimed to explore whether the mean exposure levels of workers in the same workgroup represented real noise exposure better than individual exposure levels did. Methods: A cross-sectional study was conducted to establish a model for cumulative noise exposure (CNE and hearing loss in 205 occupational noise-exposed workers who were recruited from two large automobile manufacturers in China. We used a personal noise dosimeter and a questionnaire to determine the workers′ occupational noise exposure levels and exposure times, respectively. A qualified audiologist used standardized audiometric procedures to assess hearing acuity after at least 16 h of noise avoidance. Results: We observed that 88.3% of workers were exposed to more than 85 dB(A of occupational noise (mean: 89.3 ± 4.2 dB(A. The personal CNE (CNEp and workgroup CNE (CNEg were 100.5 ± 4.7 dB(A and 100.5 ± 2.9 dB(A, respectively. In the binary logistic regression analysis, we established a regression model with high-frequency hearing loss as the dependent variable and CNE as the independent variable. The Wald value was 5.014 with CNEp as the independent variable and 8.653 with CNEg as the independent variable. Furthermore, we found that the figure for CNEg was more similar to the stationary noise reference than CNEp was. The CNEg model was better than the CNEp model. In this circumstance, we can measure some subjects instead of the whole workgroup and save manpower. Conclusions: In a complex noise environment, the measurements of average noise exposure level of the workgroup can improve the accuracy and save manpower.

    Psychosocial work factors can affect depressive moods, but research is inconclusive if flexibility to self-determine working hours (work-time control, WTC) is associated with depressive symptoms over time. We investigated if either sub-dimension of WTC, control over daily hours and control over time off, was related to depressive symptoms over time and examined causal, reversed-causal, and reciprocal pathways. The study was based on four waves of the Swedish Longitudinal Occupational Survey of Health which is a follow-up of representative samples of the Swedish working population. WTC was measured using a 5-item index. Depressive symptoms were assessed with a brief subscale of the Symptom Checklist. Latent growth curve models and cross-lagged panel models were tested. Best fit was found for a model with correlated intercepts (control over daily hours) and both correlated intercepts and slopes (control over time off) between WTC and depressive symptoms, with stronger associations for control over time off. Causal models estimating impacts from WTC to subsequent depressive symptoms were best fitting, with a standardised coefficient between -0.023 and -0.048. Results were mainly based on self-report data and mean age in the study sample was relatively high. Higher WTC was related to fewer depressive symptoms over time albeit small effects. Giving workers control over working hours - especially over taking breaks and vacation - may improve working conditions and buffer against developing depression, potentially by enabling workers to recover more easily and promoting work-life balance.

    Full Text Available Abstract Background Socioeconomic status (SES is an important determinant of population health. Explanatory approaches on how SES determines health have so far included numerous factors, amongst them psychosocial factors such as social relationships. However, it is unclear whether social relationships can help explain socioeconomic differences in general subjective health. Do different aspects of social relationships contribute differently to the explanation? Based on a cohort study of middle and older aged residents (45 to 75 years from the Ruhr Area in Germany our study tries to clarify the matter. Methods For the analyses data from the population-based prospective Heinz Nixdorf Recall (HNR Study is used. As indicators of SES education, equivalent household income and occupational status were employed. Social relations were assessed by including structural as well as functional aspects. Structural aspects were estimated by the Social Integration Index (SII and functional aspects were measured by availability of emotional and instrumental support. Data on general subjective health status was available for both baseline examination (2000–2003 and a 5-year follow-up (2006–2008. The sample consists of 4,146 men and women. Four logistic regression models were calculated: in the first model we controlled for age and subjective health at baseline, while in models 2 and 3, either functional or structural aspects of social relationships were introduced separately. Model 4 then included all variables. As former studies indicated different health effects of SES and social relations in men and women, analyses were conducted with the overall sample as well as for each gender alone. Results Prospective associations of SES and subjective health were reduced after introducing social relationships into the regression models. Percentage reductions between 2% and 30% were observed in the overall sample when all aspects of social relations were included. The

    Paul T Williams

    Full Text Available PURPOSE: Test whether: 1 walking intensity predicts mortality when adjusted for walking energy expenditure, and 2 slow walking pace (≥24-minute mile identifies subjects at substantially elevated risk for mortality. METHODS: Hazard ratios from Cox proportional survival analyses of all-cause and cause-specific mortality vs. usual walking pace (min/mile in 7,374 male and 31,607 female recreational walkers. Survival times were left censored for age at entry into the study. Other causes of death were treated as a competing risk for the analyses of cause-specific mortality. All analyses were adjusted for sex, education, baseline smoking, prior heart attack, aspirin use, diet, BMI, and walking energy expenditure. Deaths within one year of baseline were excluded. RESULTS: The National Death Index identified 1968 deaths during the average 9.4-year mortality surveillance. Each additional minute per mile in walking pace was associated with an increased risk of mortality due to all causes (1.8% increase, P=10(-5, cardiovascular diseases (2.4% increase, P=0.001, 637 deaths, ischemic heart disease (2.8% increase, P=0.003, 336 deaths, heart failure (6.5% increase, P=0.001, 36 deaths, hypertensive heart disease (6.2% increase, P=0.01, 31 deaths, diabetes (6.3% increase, P=0.004, 32 deaths, and dementia (6.6% increase, P=0.0004, 44 deaths. Those reporting a pace slower than a 24-minute mile were at increased risk for mortality due to all-causes (44.3% increased risk, P=0.0001, cardiovascular diseases (43.9% increased risk, P=0.03, and dementia (5.0-fold increased risk, P=0.0002 even though they satisfied the current exercise recommendations by walking ≥7.5 metabolic equivalent (MET-hours per week. CONCLUSIONS: The risk for mortality: 1 decreases in association with walking intensity, and 2 increases substantially in association for walking pace ≥24 minute mile (equivalent to <400 m during a six-minute walk test even among subjects who exercise regularly.

    This study investigates the conflict between work and private life (work-life conflict and life-work conflict) and its relationship with burnout among physicians in breast cancer centers in North Rhine-Westphalia (n=378). With regard to the construct burnout, we differentiated between the 3 subscales emotional exhaustion, depersonalisation and personal accomplishment of the Maslach burnout inventory. In a structural equation model it was seen that above all the work-life conflict is positively associated with emotional exhaustion whereas the life-work conflict has a stronger positive correlation with depersonalisation and a negative relationship with personal accomplishment. Altogether, the results emphasise the importance of a successful interaction between professional work and private life ("work-life balance") for the health of medical personnel. © Georg Thieme Verlag KG Stuttgart · New York.

    The burden of cerebral small vessel disease, sleep disorders, and chronic kidney disease is on the rise in remote rural settings. However, information on potential links between these conditions is limited. We aimed to assess the relationships between these conditions in community-dwelling older adults living in rural Ecuador. Atahualpa residents aged ≥60 years were offered a brain MRI. A venous blood sample was obtained for serum creatinine determination. Baseline interviews and procedures were directed to assess demographics, cardiovascular risk factors, and sleep quality. Using generalized structural equation modeling (GSEM), we assessed the associations between white matter hyperintensities (WMH) of vascular origin, sleep quality and kidney function, as well as the directions of the relationships between these variables. Of 423 candidates, 314 (74%) were enrolled. Moderate-to-severe WMH were noticed in 74 (24%) individuals, poor sleep quality in 101 (31%), and moderate-to-severe chronic kidney disease in 28 (9%). GSEM showed that the direction of the effect was from kidney function to WMH and from the latter to sleep quality. Of independent variables investigated, worse kidney function was associated with age, high glucose levels and male sex. WMH was associated with cholesterol blood levels, blood pressure, level of education and severe edentulism. Poor sleep quality was associated with poor physical activity. This population based study shows that chronic kidney disease is associated with increased severity of WMH, which, in turn, is associated with a poor sleep quality. Copyright © 2017 Elsevier B.V.

    Evidence delineating the effects of haemophilia on interpersonal relationships is sparse and largely outdated, failing to reflect the impact of current treatment strategies. HERO (Haemophilia Experiences, Results and Opportunities) was commenced to garner a more comprehensive understanding of psychosocial issues facing persons with haemophilia (PWH). This article describes the findings of the quantitative HERO survey relating to the influence of haemophilia on interpersonal relationships of adult PWH, and parents/caregivers of children with haemophilia. Separate questionnaires were completed by adult PWH and parents of minor children from 10 countries, including satisfaction with support from partners, family, friends and other social contacts; disclosure of haemophilia and carrier status and family dynamics. A total of 675 PWH and 561 parents completed the survey. Over half of PWH (57%) and parents (84%) were married. Most PWH were satisfied with support from partners (94%), family (90%) and friends (85%), with lower percentages reported among those with inhibitors. Most parents were likewise satisfied with support from partners (88%) and family (83%). Whereas PWH were reticent to disclose their diagnosis beyond family and friends, parents were more likely to share their son's diagnosis, and most were satisfied with the support from their son's peers (74%), teachers (83%) and other adults in supervisory roles (85%). PWH and parents surveyed were satisfied overall with the support they received from partners, family, friends and social contacts. Relationships are affected by haemophilia in various ways, and particularly affected in terms of disease burden, age and social life. © 2014 John Wiley & Sons Ltd.

    Adequate knowledge on environmental correlates of physical activity (PA) in older adults is needed to develop effective health promotion initiatives. However, research in this age group is scarce and most existing studies were conducted in North America. The present study aimed to examine relationships between GIS-based neighborhood walkability and objective and self-reported PA in community-dwelling Belgian older adults. Furthermore, moderating effects of neighborhood income levels were investigated. The Belgian Environmental Physical Activity Study (BEPAS) for Seniors is a cross-sectional study in older adults (≥65 yrs) and was conducted between October 2010 and September 2012. Data from 438 older adults living in 20 neighborhoods across Ghent (Belgium) were analyzed. Stratification of selected neighborhoods was based upon objective walkability and neighborhood income. Participants wore an accelerometer during seven consecutive days to obtain objective levels of moderate-to-vigorous physical activity (MVPA). Self-reported levels of transportation walking/cycling and recreational walking/cycling were assessed using the International Physical Activity Questionnaire (long, last 7 days version) adapted for the elderly. Multi-level regression analyses were conducted. Findings showed a positive relationship between neighborhood walkability and weekly minutes of older adults' self-reported walking for transportation (B = 4.63 ± 1.05;p walkability and accelerometer-derived low-light PA (B = -1.38 ± 0.62;p = 0.025). Walkability was not related to any measure of recreational PA. A walkability x income interaction was found for accelerometer-derived MVPA (B = -1.826 ± 1.03;p = 0.075), showing only a positive association between walkability and MVPA in low-income neighborhood residents. This was the first European study to examine walkability-PA relationships in older adults. These Belgian findings suggest that a high neighborhood walkability relates to higher levels

Methods: The cluster-randomized field experiment included heterosexual couples from a high-density South African township in which neighborhoods were randomized to one of the intervention arms or a control arm that received the WHC only. Participants completed in-person study visits at baseline and 6-month follow-up. We examined group differences using one-way analysis of variance and multivariable regression models.Results: Of the 290 couples enrolled, 255 women remained in the same partnership over 6 months. Following the intervention, women in the CHC arm compared with those in the WHC arm were more likely to report an increase in relationship control (ß=0.92, 95% confidence interval [CI]: 0.02, 1.83, P=0.045 and gender norms supporting female autonomy in relationships (ß=0.99, 95% CI: 0.07, 1.91, P=0.035.

    Naphthalene is an important contaminant in indoor and outdoor air. Acute overexposure can have toxic effects, resulting in hemolysis. There have been no studies evaluating the impact of environmental exposure on red blood cell indices. We examined 1- and 2-hydroxynaphthalene urinary metabolites (NAP1 and NAP2) in non-Hispanic White, non-Hispanic Black, and Mexican-American adults in the USA and their relationship with hemoglobin (Hb) and hematocrit (HCT). Using the 2003-2004 National Health and Nutrition Examination Survey data, weighted generalized linear regression analyses were used to examine the association between Hb (in grams per deciliter) and HCT (in percent) with NAP1 and NAP2 (per 100,000 ng/L). Beta coefficients ± SE are reported. NAP1 and NAP2 were highest in non-Hispanic Blacks, followed by non-Hispanic Whites, and lowest in Mexican-American adults. There was a positive association between NAP1 and Hb (0.39 ± 0.11, p = 0.0034) and HCT (1.14 ± 0.28, p = 0.0009) after adjusting for age, gender, race, education, and smoking. Stratified analysis by smoking showed similar results with the association being stronger for smokers (Hb 0.63 ± 0.23, p = 0.02; HCT 1.43 ± 0.79, p = 0.09) than nonsmokers (Hb 0.34 ± 0.14, p = 0.03; HCT 1.08 ± 0.42, p = 0.02). The association was also stronger for non-Hispanic blacks (Hb 0.54 ± 0.20, p = 0.02; HCT 1.43 ± 0.55, p = 0.02) than for non-Hispanic whites (Hb 0.37 ± 0.18, p = 0.06; HCT 1.20 ± 0.51, p = 0.03) and was not significant for Mexican-Americans (Hb 0.30 ± 1.7, p = 0.10; HCT 0.99 ± 0.52, p = 0.08). NAP2 was not significantly associated with Hb or HCT. The observed disparity in NAP1 and NAP2 levels by race/ethnicity is consistent with published literature. The origin of these differences in exposure is unclear but may reflect differences in environmental exposure as well as genetic susceptibility. The

    BACKGROUND: Growing evidence suggests that cerebral white-matter changes and depressive symptoms are linked directly along the causal pathway. We investigated whether baseline severity of cerebral white-matter changes predict longer-term future depressive outcomes in a community sample of non...... volumetrically. Depressive outcomes were assessed in terms of depressive episodes and depressive symptoms, as measured by the Geriatric Depression Scale (GDS). Subjects were clinically reassessed annually for up to 3 years. Regression models were constructed to determine whether baseline severity of white.......09) or incident depression (p=0.08). CONCLUSIONS: Our results support the vascular depression hypothesis and strongly implicate white-matter changes in the pathogenesis of late-life depression. Furthermore, the findings indicate that, over time, part of the relationship between white-matter changes and depression...

  7. Recent results on the linearity of the dose-response relationship for radiation-induced mutations in human cells by low dose levels

    Five studies made by various authors in the last years are discussed, which are significant in that the response of human cells to low-dose irradiation is determined directly and not by extrapolation, and which also provide information on the mutagenic effects of low radiation doses. The results of these studies do not indicate any other than a linear response for induction of mutations by low-dose irradiation, nor are there any reasons observable for assuming the existence of a threshold dose. It is very likely therefore that cancer initiation at the low dose level also is characterized by a linear relationship. Although threshold dose levels cannot generally be excluded, and maybe are only too low to be detected by experiment, there is no plausible biophysical argument for assuming the existence of such microdose threshold.

    We review the use of behavior from television game shows to infer risk attitudes. These shows provide evidence when contestants are making decisions over very large stakes, and in a replicated, structured way. Inferences are generally confounded by the subjective assessment of skill in some games......, and the dynamic nature of the task in most games. We consider the game shows Card Sharks, Jeopardy!, Lingo, and finally Deal Or No Deal. We provide a detailed case study of the analyses of Deal Or No Deal, since it is suitable for inference about risk attitudes and has attracted considerable attention....

  9. Radioactive waste: show time? - 16309

    Time will render radioactive waste harmless. How can we manage the time radioactive substances remain harmful? Just 'wait and see' or 'marking time' is not an option. We need to isolate the waste from our living environment and control it as long as necessary. For the situation in the Netherlands, it is obvious that a period of long term storage is needed. Both the small volume of waste and the limited financial possibilities are determining factors. Time is needed to let the volume of waste grow and to let the money, needed for disposal, grow in a capital growth fund. An organisation such as COVRA - the radioactive waste organisation in the Netherlands - can only function when it has good, open and transparent relationship with the public and particularly with the local population. If we tell people that we safely store radioactive waste for 100 years, they often ask: 'That long?' How can we explain the long-term aspect of radioactive waste management in a way people can relate to? In this paper, an overview is given of the activities of COVRA on the communication of radioactive waste management. (authors)

    Background: The "meeting-in-the-middle" (MITM) is a principle to identify exposure biomarkers that are also predictors of disease. The MITM statistical framework was applied in a nested case-control study of hepatocellular carcinoma (HCC) within European Prospective Investigation into Cancer and Nutrition (EPIC), where healthy lifestyle index (HLI) variables were related to targeted serum metabolites. Methods: Lifestyle and targeted metabolomic data were available from 147 incident HCC cases and 147 matched controls. Partial least squares analysis related 7 lifestyle variables from a modified HLI to a set of 132 serum-measured metabolites and a liver function score. Mediation analysis evaluated whether metabolic profiles mediated the relationship between each lifestyle exposure and HCC risk. Results: Exposure-related metabolic signatures were identified. Particularly, the body mass index (BMI)-associated metabolic component was positively related to glutamic acid, tyrosine, PC aaC38:3, and liver function score and negatively to lysoPC aC17:0 and aC18:2. The lifetime alcohol-specific signature had negative loadings on sphingomyelins (SM C16:1, C18:1, SM(OH) C14:1, C16:1 and C22:2). Both exposures were associated with increased HCC with total effects (TE) = 1.23 (95% confidence interval = 0.93-1.62) and 1.40 (1.14-1.72), respectively, for BMI and alcohol consumption. Both metabolic signatures mediated the association between BMI and lifetime alcohol consumption and HCC with natural indirect effects, respectively, equal to 1.56 (1.24-1.96) and 1.09 (1.03-1.15), accounting for a proportion mediated of 100% and 24%. Conclusions: In a refined MITM framework, relevant metabolic signatures were identified as mediators in the relationship between lifestyle exposures and HCC risk. Impact: The understanding of the biological basis for the relationship between modifiable exposures and cancer would pave avenues for clinical and public health interventions on metabolic mediators

The hybrid electric-powered vehicles or those equipped with fuel cells have been highlighted by the Japanese manufacturers which allow considerable budgets in the research of less polluting vehicles. The exposed models, although being all different according to the manufacturer, use always a hybrid system: fuel cell/battery. The manufacturers have stressed too on the intelligent systems for navigation and safety as well as on the design and comfort. (O.M.)

    Several studies have confirmed that smoking is a risk factor for depression in adolescence. These studies have not controlled for other lifestyle factors. The aim of this longitudinal study was to assess the relationship between smoking and depressive symptoms, controlling for other lifestyle factors. This school-based longitudinal self-report survey was conducted among 15- and 18-year-old students in Oslo, Norway. From a baseline cohort of 3811 students, 2489 (65%) participants were followed up after 3 years and completed questionnaires at baseline and follow-up. Mental distress was assessed with Hopkins Symptom Checklist, version 10. There was a statistically significant association between daily smoking at age 15 and mental distress at age 18 for girls, but not for boys (odds ratio [OR]=2.0 [1.5-2.8] and 1.3 [0.7-2.4], respectively). In girls, the association remained statistically significant even after adjustment for sociodemographic variables and several lifestyle factors. In an analysis of 15-years-old "never smokers," a statistically significant association was found between smoking and mental distress for both genders at age 18. Mentally distressed adolescents at age 15 did not show a higher proportion of smoking at age 18 compared with those not distressed. In addition to supporting earlier findings that smoking seems to be causally related to depressive symptoms among adolescent girls, the contribution of this study is that this association only to some extent is confounded by other unhealthy lifestyle habits.

    Research has shown that psychosocial stress acts as a risk factor for mental disorders. The present study aims at processing the preliminary results of the Hungarian Survey of Work Stress, concerning the relationship between depressive symptoms and work stress. Cross-sectional survey among Hungarian workers was carried out (n = 1058, 27.5% man, 72.5% woman, age 37.2 years, SD = 11 years). Psychosocial factors were measured using the COPSOQ II questionnaire, while BDI-9 was used for the assessment of depressive symptoms. Statistical analysis was carried out applying Spearman's correlation and logistic regression. A quarter of the workers reported moderate or severe symptoms of depression (BDI≥19). The study confirmed the association between depressive symptoms and work-family conflict (OR = 2.21, CI: 1.82-2.68), possibilities for development (OR = 0.76, CI: 0.59-0.97) meaning of work (OR = 0.69, CI: 0.59-0.89) and commitment (OR = 0.60, CI: 0.47-0.78). The results point toward the need of such organizational measures that allow for the reduction of psychosocial stress.

    Medical knowledge (MK) in residents is commonly assessed by the in-training examination (ITE) and faculty evaluations of resident performance. We assessed the reliability of clinical evaluations of residents by faculty and the relationship between faculty assessments of resident performance and ITE scores. We conducted a cross-sectional, observational study at an academic emergency department with a postgraduate year (PGY)-1 to PGY-3 emergency medicine residency program, comparing summative, quarterly, faculty evaluation data for MK and overall clinical competency (OC) with annual ITE scores, accounting for PGY level. We also assessed the reliability of faculty evaluations using a random effects, intraclass correlation analysis. We analyzed data for 59 emergency medicine residents during a 6-year period. Faculty evaluations of MK and OC were highly reliable (κ  =  0.99) and remained reliable after stratification by year of training (mean κ  =  0.68-0.84). Assessments of resident performance (MK and OC) and the ITE increased with PGY level. The MK and OC results had high correlations with PGY level, and ITE scores correlated moderately with PGY. The OC and MK results had a moderate correlation with ITE score. When residents were grouped by PGY level, there was no significant correlation between MK as assessed by the faculty and the ITE score. Resident clinical performance and ITE scores both increase with resident PGY level, but ITE scores do not predict resident clinical performance compared with peers at their PGY level.

    O fenômeno dos reality shows - e a subseqüente relação entre imagem e verdade - assenta-se sobre uma série de paradoxos. Tais paradoxos podem ser compreendidos à luz do pensamento do filósofo alemão Friedrich Nietzsche, que, através dos usos de formulações paradoxais, concebia a realidade como um mundo de pura aparência e a verdade como um acréscimo ficcional, como um efeito. A ficção é então tomada, na filosofia de Nietzsche, não em seu aspecto falsificante e desrealizador - como sempre pleiteou nossa tradição metafísica -, mas como condição necessária para que certa espécie de invenção possa operar como verdade. Sendo assim, a própria expressão reality show, através de sua formulação paradoxal, engendra explicitamente um mundo de pura aparência, em que a verdade, a parte reality da proposição, é da ordem do suplemento, daquilo que se acrescenta ficcionalmente - como um adjetivo - a show. O ornamento, nesse caso, passa a ocupar o lugar central, apontando para o efeito produzido: o efeito-de-verdade. Seguindo, então, o pensamento nietzschiano e sua atualização na contemporaneidade, investigaremos de que forma os televisivos “shows de realidade” operam paradoxalmente, em consonância com nossas paradoxais práticas culturais.

    Erectile dysfunction (ED) can significantly impact a man's relationships and well-being. We assessed changes in self-esteem, confidence, sexual relationship satisfaction, and overall relationship satisfaction in men with ED using the validated Self-Esteem And Relationship questionnaire (SEAR). This was a 12-week, double-blind, placebo-controlled, flexible-dose (25, 50, 100 mg, as needed) international study of sildenafil in men > or =18 years of age in Mexico, Brazil, Australia, and Japan. The primary study outcome was change in self-esteem from baseline to the end of treatment. Secondary study measures were changes in other SEAR components, International Index of Erectile Function (IIEF) domains, percentage of intercourse attempts that were successful, and the response to a global efficacy question at the end of treatment. Patients were well balanced for age and duration of ED (placebo = 149 and sildenafil = 151). Compared with placebo, sildenafil significantly improved self-esteem, confidence, sexual relationship satisfaction, and overall relationship satisfaction (P relationship satisfaction, and overall relationship satisfaction after treatment of ED with sildenafil were consistent among countries. These data suggest a substantial cross-cultural improvement in well-being after successful treatment of ED with sildenafil.

    This study investigates the possible relationship between pathological gambling (PG) and potential spectrum disorders including the DSM-IV impulse control disorders (intermittent explosive disorder, kleptomania, pyromania, trichotillomania) and several non-DSM disorders (compulsive buying disorder, compulsive sexual behavior, Internet addiction). PG probands, controls, and their first-degree relatives were assessed with instruments of known reliability. Detailed family history information was collected on relatives who were deceased or unavailable. Best estimate diagnoses were assigned blind to family status. The results were analyzed using logistic regression by the method of generalized estimating equations. The sample included 95 probands with PG, 91 controls, and 1075 first-degree relatives (537 PG, 538 controls). Compulsive buying disorder and having "any spectrum disorder" were more frequent in the PG probands and their first-degree relatives vs. controls and their relatives. Spectrum disorders were significantly more prevalent among PG relatives compared to control relatives (adjusted OR=8.37), though much of this difference was attributable to the contribution from compulsive buying disorder. We conclude that compulsive buying disorder is likely part of familial PG spectrum. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Childhood maltreatment represents an important public health concern, as it is often associated with a host of negative outcomes across development. In recent years, researchers have begun to examine the link between negative health-related behaviors and history of childhood maltreatment. The current study considers the relationship between history of childhood maltreatment and sleep disturbances in adolescence. Further, the role of psychological distress is considered as an explanatory link between childhood maltreatment and adolescent sleep disturbances. The current study is a secondary analysis using a subsample (N=73) of child welfare-involved youth who participated in the initial and 2-year time-point of the Maltreatment and Adolescent Pathways (MAP) Longitudinal Study on the variables of interest. Youth reported on lifetime maltreatment experiences, psychological distress, and sleep disturbances, in addition to the other measures administered as part of the larger MAP study protocol. More severe childhood maltreatment was related to increased sleep disturbances during adolescence, and psychological distress was a significant mediator of the childhood maltreatment-adolescent sleep disturbance association. The results demonstrate that a history of childhood maltreatment represents a risk factor for sleep disturbances in adolescence. The findings highlight the importance of inquiring about health-related behaviors in child welfare youth and the need to promote psychological well-being within this population.

    BACKGROUND: Cerebral microembolic signals (MES) may predict increased stroke risk in carotid stenosis. However, the relationship between platelet counts or platelet activation status and MES in symptomatic versus asymptomatic carotid stenosis has not been comprehensively assessed. SETTING: University teaching hospitals. METHODS: This prospective, pilot observational study assessed platelet counts and platelet activation status, and the relationship between platelet activation and MES in asymptomatic versus early (≤4 weeks after TIA\\/stroke) and late phase (≥3 months) symptomatic moderate or severe (≥50%) carotid stenosis patients. Full blood count measurements were performed, and whole blood flow cytometry was used to quantify platelet surface activation marker expression (CD62P and CD63) and circulating leucocyte-platelet complexes. Bilateral simultaneous transcranial Doppler ultrasound monitoring of the middle cerebral arteries was performed for 1 hour to classify patients as MES-positive or MES-negative. RESULTS: Data from 31 asymptomatic patients were compared with 46 symptomatic patients in the early phase, and 35 of these patients followed up to the late phase after symptom onset. The median platelet count (211 vs. 200 x 10(9) \\/L; p=0.03) and the median% lymphocyte-platelet complexes were higher in early symptomatic than asymptomatic patients (2.8 vs. 2.4%, p=0.001). The% lymphocyte-platelet complexes was higher in early symptomatic than asymptomatic patients with ≥70% carotid stenosis (p=0.0005), and in symptomatic patients recruited within 7 days of symptom onset (p=0.028). Complete TCD data were available in 25 asymptomatic and 31 early phase symptomatic, and 27 late phase symptomatic patients. 12% of asymptomatic versus 32% of early phase symptomatic (p=0.02) and 19% of late phase symptomatic patients (p=0.2) were MES-positive. Early symptomatic MES-negative patients had a higher% lymphocyte-platelet complexes than asymptomatic MES

    To investigate the relationship between serum PSA level, Gleason score of PCa and the outcomes of Ga 68 -PSMA PET/CT in patients with recurrent PCa. A total of 109 consecutive patients (median age 71 years; range 48-89 years) who had PSA recurrence after RP and/or hormonotherapy and/or radiotherapy were included in this study. Local recurrences, lymph node metastasis (pelvic, abdominal and/or supradiaphragmatic), bone metastases (oligometastatic/multimetastatic) and other metastatic sites (lung, liver, brain, etc) were documented. In 91(83.4%) patients at least one lesion characteristic for PCa was detected by 68 Ga-PSMA PET/CT. The median serum total PSA (tPSA) was 6.5 (0.2-640) ng/ml.There was a significant difference between 68 Ga-PSMA PET/CT positive and negative patients in terms of serum total PSA value. No statistical significance was found between positive and negative 68 Ga-PSMA PET/CT findings in terms of Gleason score. Local recurrence was detected in 56 patients. whereas lymph node metastases were demonstrated in 46 patients. Pelvic nodal disease was the most frequent presentation followed by abdominal and supradiaphragmaticnodal involvement. Bone metastases [oligometastasis, (n = 20); multimetastasis, (n = 35)⦌ were also detected in 55 patients. In the ROC analysis for the study cohort, the optimal cut-off value of total serum PSA was determined as 0.67 ng/ml for distinguishing between positive and negative 68 Ga-PSMA PET/CT images, with an area under curve of 0.952 (95% CI 0.911-0.993). 68 Ga-PSMA PET/CT was found to be an effective tool for the detection of recurrent PCa. Even though no relationship was detected between the GS and 68 Ga-PSMA PET/CT findings, serum total PSA values may be used for estimating the likelihood of positive 68 Ga-PSMA PET/CT results.

    There has been much discussion concerning the economics of using biomass for the production of substitute fuels and it has been argued that the net energy gain could be small or even negative. The development of the ATPAL process is described and it is claimed that only one quarter of the energy equivalent contained in the alcohol will be consumed in the total process. Both the pilot plant and a commercial scale plant with some modifications are described. The most significant advantage claimed for the ATPAL process is in its low process energy savings resulting from mechanical vapour recompression, recycling the heat and production of a low volume of effluent.

    Full Text Available BACKGROUND: Sexual way of HIV transmission in Ukraine outweighs parenteral route since 2007. In response to situation change couple’s counseling for IDUs was introduced and is currently tested within randomized trial.METHODS: Baseline data were collected in June-September 2011: 548 IDU couples in 10 cities were surveyed and screened for HIV and Hepatitis C. Participants were recruited using respondent-driven sampling method. RESULTS: The average age of participants varied between 30 – 33 years old with women being 3 years younger. On many aspects drug using couples in long-term relationships share the same values as non-drug using couples. However, drug use resulted into specific HIV/STIs risks for the couple. Common reasons of being with the current partner included mutual understanding (98%; similar life styles (90%; understanding life with addiction (88%; and love (87%. At the same time, looking at the quality time partners spend together, it was found that mostly, they are connected by their drug use, fear of social exclusion and economical reasons. Although these factors are important for both men and women, they have a bigger impact on women and put them into more vulnerable position: 25% have children who in 59% of cases mostly live with mother and her partner; 40% live in a partner’s house; 30% are financially supported by partners; 77% women get drugs from partners and only 20% are first one to be injected. Trust also seems to be an issue. Thus, 83% of respondents believe that they know the HIV/STI status of their partner and 90% of those believe it to be negative, while 20% of those surveyed appeared to be HIV positive and about 30% Hepatitis C positive. CONCLUSIONS: Understanding characteristics of sexual partners is crucial for HIV prevention programme design and implementation.

    A fact-finding questionnaire survey on medical exposure in Aomori Prefecture was conducted in September 1998. Of the 23 exposed sites in the body investigated, exposure at 17 sites in adults was investigated in terms of the type of high-voltage generator, imaging conditions (X-ray tube voltage, electric current, exposure time, etc.), photosensitive materials and relative photosensitivity, and entrance surface doses. At 6 of the 17 exposed sites, the relationships between these technical conditions and entrance surface doses were analyzed to consider further reduction of medical exposure. The most frequently used high-voltage generators were inverter generators (about 52%). In many institutions, additional filters were utilized for high-voltage imaging of the chest. Highly sensitive green-emission materials were the most frequently used photosensitive materials (73%). These findings indicate that many institutions are attempting to reduce exposure. Entrance surface doses varied greatly among institutions: and a 100-fold difference was observed in exposure to the chest, Martius, and the pelvis. Further efforts to lower entrance surface doses are therefore necessary to reduce medical exposure. Negative correlations were observed between electric voltage, electric current, and exposure time. Examination of the relationships between entrance surface doses, electric current, and exposure time yielded positive correlations. However, the entrance surface doses may not have been properly calculated in some institutions, and examination of the relationship between the relative sensitivity of the sensitive material and entrance surface doses showed great variability in entrance surface doses between institutions. Based on the above results, it is concluded that further reduction of medical exposure is possible, not only by improving the accuracy of X-ray units/devices, but by choosing a more appropriate of conditions to perform radiography.

    Existing work on the effects of social network sites (SNS) on well-being has often stressed that SNS can help people gain social support from their online networks, which positively affects their well-being. However, the majority of studies in this area have been cross-sectional in nature and/or relied on student samples. Using data from six waves of a longitudinal study with a representative sample of Dutch Internet users, we first examined whether users and nonusers of SNS differ in online social support and well-being (as indicated by life satisfaction and stress). In a second step, we investigated in more detail how SNS use - more specifically, asking for advice and the number of strong ties on these SNS - are related to online social support, stress, and satisfaction with life. Overall, our results provide no evidence for SNS use and online social support affecting either stress or life satisfaction. SNS users reported more online social support than nonusers did, but also higher levels of stress; the two groups did not differ in overall life satisfaction. With regard to the underlying processes, we found positive cross-sectional and longitudinal relationships between asking for advice on SNS and online social support, indicating that SNS can be an effective tool for receiving social support. However, online social support was not related to higher life satisfaction or reduced stress 6 months later; instead, it seems that SNS users with lower life satisfaction and/or higher stress seek more social support online by asking for advice on SNS.

    To investigate the association between the quality of the family physician-patient relationship and frequent attendance of primary and specialist health care. Cross-sectional survey of a representative German population sample (N=2.266). Family physician-patient relationship was assessed with the Patient Doctor Relationship Questionnaire (PDRQ-9). Determinants of frequent attendance were analyzed using logistic regression. Frequent attendance of family physicians was associated with lower income (OR 1.43, 95% CI 1.02-2.00), not being in paid work (OR 1.58, CI 1.08-2.30), psychological distress (OR 1.14, CI 1.07-1.22), somatic symptoms (OR 1.07, CI 1.04-1.11), and physical comorbidity (OR 1.54, CI 1.36-1.74) in the multivariate analysis. Frequent attendance of specialists was related to psychological distress (OR 1.12, CI 1.04-1.20), somatic symptoms (OR 1.08, CI 1.04-1.11), and physical comorbidity (OR 1.69, CI 1.48-1.93) in the multivariate analysis. Quality of the relationship was associated with frequent attendance only in the univariate analyses. A stronger relationship with the family physician was not associated with reduced contact with specialists. The quality of the family physician-patient relationship is not independently associated with frequent attendance. Family physicians should be aware that need factors, i.e. symptom burden and physical comorbidities, are main drivers of frequent attendance. Copyright © 2016 Elsevier Ireland Ltd.

    Socioeconomic status (SES) is an important determinant of population health. Explanatory approaches on how SES determines health have so far included numerous factors, amongst them psychosocial factors such as social relationships. However, it is unclear whether social relationships can help explain socioeconomic differences in general subjective health. Do different aspects of social relationships contribute differently to the explanation? Based on a cohort study of middle and older aged residents (45 to 75 years) from the Ruhr Area in Germany our study tries to clarify the matter. For the analyses data from the population-based prospective Heinz Nixdorf Recall (HNR) Study is used. As indicators of SES education, equivalent household income and occupational status were employed. Social relations were assessed by including structural as well as functional aspects. Structural aspects were estimated by the Social Integration Index (SII) and functional aspects were measured by availability of emotional and instrumental support. Data on general subjective health status was available for both baseline examination (2000-2003) and a 5-year follow-up (2006-2008). The sample consists of 4,146 men and women. Four logistic regression models were calculated: in the first model we controlled for age and subjective health at baseline, while in models 2 and 3, either functional or structural aspects of social relationships were introduced separately. Model 4 then included all variables. As former studies indicated different health effects of SES and social relations in men and women, analyses were conducted with the overall sample as well as for each gender alone. Prospective associations of SES and subjective health were reduced after introducing social relationships into the regression models. Percentage reductions between 2% and 30% were observed in the overall sample when all aspects of social relations were included. The percentage reductions were strongest in the lowest SES

    Healthy eating is a critical aspect of the prevention and management of type 2 diabetes (T2DM). Disrupted eating patterns can result in poor glucose control and increase the likelihood of diabetic complications. Teneligliptin inhibits dipeptidyl peptidase-4 activity for 24 h and suppresses postprandial hyperglycemia after all three daily meals. This interim analysis of data from the large-scale post-marketing surveillance of teneligliptin (RUBY) in Japan examined eating patterns and their relationship with metabolic parameters and diabetic complications. We also examined whether eating patterns affected safety and efficacy of teneligliptin. We analyzed baseline data from survey forms collected in RUBY between May 2013 and June 2017, including patient characteristics, metabolic parameters, and eating patterns (eating three meals per day or not; timing of evening meal) before teneligliptin treatment was initiated. Safety and efficacy of 12 months' teneligliptin (20-40 mg/day) treatment was assessed. Data from 10,532 patients were available for analysis. Most patients who did not eat three meals per day (n  =757) or who ate their evening meal after 10 PM (n  =206) were 64 years old or younger. At baseline, glycated hemoglobin (HbA1c), fasting blood glucose, triglycerides, total and low-density lipoprotein cholesterol, body mass index, alanine aminotransferase, and aspartate aminotransferase levels were higher in those patients who did not eat three meals per day (p < 0.05) or who ate their evening meal late (p < 0.05). Diabetic complications were more common in patients who did not eat three meals per day. Treatment with teneligliptin reduced HbA1c over 6 or 12 months across all eating patterns, with a low incidence of adverse drug reactions. Eating patterns may be associated with altered metabolic parameters and diabetic complications among Japanese patients with T2DM. Teneligliptin may be well tolerated and improve hyperglycemia in patients

    To evaluate potential correlation between the extent and site of avascular necrosis (AVN), as determined by preoperative magnetic resonance (MR) imaging, and the development of femoral head collapse. Using clinical, radiographic and MR imaging criteria, twenty hips in 15 patients were selected for core decompression. Preoperative MR results were classified into three categories: group A, less than 15% involvement of the weight-bearing portion of the femoral head; group B, 15%-30% involvement; group C, more than 30% involvement, according to ARCO staging. We also established three groups according to site of involvement of the femoral head namely medial, middle and lateral. Of 20 cases, three were stage Ia; two, Ib; four, Ic; three, 2a; two, 2b; and 6, 2c. Ten cases of Ia, Ib, 2a or 2b showed no femoral head collapse during follow-up of at least 24 months, while ten cases of Ic or 2c showed femoral head collapse. The prognosis of core decompression in patients with early AVN is related to the area of lesion in the femoral head.

    Several studies suggest that pain is a trigger for challenging behaviour in older adults with cognitive impairment. However, such measured relationships might be confounded due to item overlap as instruments share similar or identical items. The purpose of this study was to examine whether the frequently observed association between pain and challenging behaviour might be traced back to item overlap. This multicentre cross-sectional study was conducted in 13 nursing homes and examined pain (measure: Pain Assessment in Advanced Dementia Scale) and challenging behaviour (measure: Cohen-Mansfield Agitation Inventory) in 150 residents with severe cognitive impairment. The extent of item overlap was determined by juxtaposition of both measures' original items. As expected, comparison between these instruments revealed an extensive item overlap. The statistical relationship between the two phenomena can be traced back mainly to the contribution of the overlapping items, which renders the frequently stated relationship between pain and challenging behaviour trivial. The status quo of measuring such associations must be contested: constructs' discrimination and instruments' discrimination have to be discussed critically as item overlap may lead to biased conclusions and assumptions in research as well as to inadequate care measures in nursing practice. © 2017 John Wiley & Sons Ltd.

    In developed nations, taller children exhibit a greater propensity to overweight/obesity. This study investigates whether this height-adiposity relationship holds true for Cameroon children using two parameters of adiposity including body mass index (BMI) and waist circumference (WC). In 557 children (287 boys and 270 girls, mean age 9.0 ± 1.8 years) from the North West Region of Cameroon height, weight and WC were measured and BMI calculated. Variables were converted to standard deviation scores (SDS). Participants were divided into quartiles of height SDS, then mean of age and sex-standardized body fat parameters compared across quartiles. The frequency of excess adiposity was calculated within each quartile. Correlation and regression analysis were used to assess height-adiposity relationships. Multiple comparisons indicated a significant increase in mean BMI (-0.08 to 0.65) and WC (-0.11 to 0.87) SDSs with increasing quartiles of height SDS. Frequency of overweight/obesity and abdominal overweight/obesity was highest among children with highest height SDS (30.2 - 33.1%) and lowest in their shortest peers (0.7 - 5.0%). There was a linear relationship between height SDS and BMI SDS (R(2) = 0.087, p economies a higher height SDS is associated with a higher frequency of overweight/obesity. This is independent of the parameter used to evaluate overweight/obesity (BMI SDS or WC SDS).

    This study aims to examine bidirectional relationships between children's language skills and Inattention/Hyperactivity (IH) symptoms during preschool. Children (N = 1459) from the EDEN mother-child cohort were assessed at ages 3 and 5.5 years. Language skills were evaluated using the WPPSI-III, NEPSY and ELOLA batteries. Children's behavior, including IH symptoms, was assessed using the parent-rated Strengths & Difficulties Questionnaire (SDQ). Using a Structural Equation Modeling (SEM) approach, we examined the relationship between language skills and IH symptoms, as well as potential mediating processes. SEM analyses indicated a small negative effect of language skills at 3 years on ADHD symptoms at 5.5 years after adjusting for IH symptoms at 3 years (β =-0.12, SE = 0.04, p-value = 0.002). Interpersonal difficulties did not mediate the relationship between early language skills and later IH symptoms, nor was this association reduced after adjusting for a broad range of pre- and postnatal environmental factors and performance IQ. Among different language skills, receptive syntax at 3 years was most strongly related to IH symptoms at 5.5 years. Poor language skills at age 3 may predict IH symptoms when a child enters primary school. Implications for the understanding and the prevention of the co-occurrence of language disorders and ADHD are discussed.

  3. Mood Instability Is a Precursor of Relationship and Marital Difficulties: Results from Prospective Data from the British Health and Lifestyle Surveys

    Full Text Available The DSM system implies that affective instability is caused by reactivity to interpersonal events. We used the British Health and Lifestyle Survey that surveyed community residents in 1984 and again in 1991 to study competing hypotheses: that mood instability (MI leads to interpersonal difficulties or vice versa. We analyzed data from 5,352 persons who participated in both waves of the survey. Factor analysis of the Eysenck Personality Inventory neuroticism scale was used to derive a 4-item scale for MI. We used depression measures that were previously derived by factor analyzing the General Health Questionnaire. We tested the competing hypotheses by regressing variables at follow-up against baseline variables. The results showed that MI in 1984 clearly predicted the development of interpersonal problems in 1991. After adjusting for depression, depression becomes the main predictor of spousal difficulties, but MI remains a predictor of interpersonal difficulties with family and friends. Attempts to investigate the reverse hypothesis were ambiguous. The clinical implication is that when MI and interpersonal problems are reported, the MI should be treated first, or at least concurrently.

    To investigate the relationship between excess weight (overweight and obesity) and health-related quality of life (HRQoL) in a sample of secondary school children in Fiji, by gender, age and ethnicity. The study comprised 8947 children from forms 3-6 (age 12-18 years) in 18 secondary schools on Viti Levu, the main island of Fiji. Body mass index (BMI) was calculated from measured height and weight, and weight status was classified according to the International Obesity Task Force recommendations. HRQoL was measured by the self-report version of the Pediatric Quality of Life Inventory 4.0. HRQoL was similar in children with obesity and normal weight. Generally, this was replicated when analyzed separately by gender and ethnicity, but age stratification revealed disparities. In 12-14-year-old children, obesity was associated with better HRQoL, owing to better social and school functioning and well-being, and in 15-18-year olds with poorer HRQoL, owing to worse physical, emotional and social functioning and well-being (Cohen's d 0.2-0.3). Children with a BMI in the overweight range also reported a slightly lower HRQoL than children with a BMI in the normal weight range, but although statistically significant, the size of this difference was trivial (Cohen's d Fiji. This is in contradiction to the negative relationship between excess weight and HRQoL shown in studies from other countries and cultures. The assumption that a large body size is associated with a lower quality of life cannot be held universally. Although a generally low HRQoL among children in Fiji may be masking or overriding the potential effect of excess weight on HRQoL, socio-economic and/or socio-cultural factors, may help to explain these relationships.

  5. Comparative genomic analysis shows that avian pathogenic Escherichia coli isolate IMT5155 (O2:K1:H5; ST complex 95, ST140 shares close relationship with ST95 APEC O1:K1 and human ExPEC O18:K1 strains.

    Full Text Available Avian pathogenic E. coli and human extraintestinal pathogenic E. coli serotypes O1, O2 and O18 strains isolated from different hosts are generally located in phylogroup B2 and ST complex 95, and they share similar genetic characteristics and pathogenicity, with no or minimal host specificity. They are popular objects for the study of ExPEC genetic characteristics and pathogenesis in recent years. Here, we investigated the evolution and genetic blueprint of APEC pathotype by performing phylogenetic and comparative genome analysis of avian pathogenic E. coli strain IMT5155 (O2:K1:H5; ST complex 95, ST140 with other E. coli pathotypes. Phylogeny analyses indicated that IMT5155 has closest evolutionary relationship with APEC O1, IHE3034, and UTI89. Comparative genomic analysis showed that IMT5155 and APEC O1 shared significant genetic overlap/similarities with human ExPEC dominant O18:K1 strains (IHE3034 and UTI89. Furthermore, the unique PAI I5155 (GI-12 was identified and found to be conserved in APEC O2 serotype isolates. GI-7 and GI-16 encoding two typical T6SSs in IMT5155 might be useful markers for the identification of ExPEC dominant serotypes (O1, O2, and O18 strains. IMT5155 contained a ColV plasmid p1ColV5155, which defined the APEC pathotype. The distribution analysis of 10 sequenced ExPEC pan-genome virulence factors among 47 sequenced E. coli strains provided meaningful information for B2 APEC/ExPEC-specific virulence factors, including several adhesins, invasins, toxins, iron acquisition systems, and so on. The pathogenicity tests of IMT5155 and other APEC O1:K1 and O2:K1 serotypes strains (isolated in China through four animal models showed that they were highly virulent for avian colisepticemia and able to cause septicemia and meningitis in neonatal rats, suggesting zoonotic potential of these APEC O1:K1 and O2:K1 isolates.

    Lack of control of confounding variables, high attrition rate, and too few neurocognitive domains completed at each assessment point are some of the limitations identified in studies of the relationship between cognition and functional outcome in schizophrenia. In the ongoing Oslo multi-follow-up study 28 first episode schizophrenia patients and a pairwise matched control group (N=28) are assessed with the MATRICS Consensus Cognitive Battery (MCCB), a clinical interview, an inventory on social and role functioning and criteria of remission and recovery at several follow-up points. The current paper describes the rate of remission and full recovery, and investigates the relationship between neurocognition and functional outcome. At 2-year follow-up, 80.0% of the patients were in remission and 16.0% of them fulfilled the criteria for full recovery. The attrition rate was very low. In the follow-up period, there was a statistically significant decline in Verbal Learning and a significant improvement on Reasoning/Problem Solving and Social Cognition in the schizophrenia group, but not in the control group. This indicates a differentiated neurocognitive course. In the schizophrenia group, Attention/Vigilance and years of education at baseline were significant predictors of social and role functioning 2 years later. Copyright © 2015 Elsevier Ireland Ltd.

    This article utilizes findings from the Ohio Dental Hygiene Survey and Ohio Dentist Survey to uncover what specific dental hygiene attitudes exist relative to employment and what factors have led to job termination and to re-entry. Ohio dental hygiene employees are most satisfied with patient relationships, co-worker relationships, and flexible working hours. The dental hygienists are least satisfied with fringe benefits, financial growth, and career creativity. Salary, benefits, nor career longevity were significant factors in determining satisfaction. Dental hygienists who were not working when surveyed, said they would consider returning to practice if a better salary were available, if they could find part-time work, if there were a good wage scale with benefits, or if their own financial need changed. Thirty-six percent of the non-practitioners said they would not ever consider returning to practice due to working conditions, establishment of a new career, or inadequate compensation. Dentist employers stated that they were satisfied or very satisfied with their dental hygienists' patient care and contribution to the practice.

    Using data from a nationally representative survey, the Canadian Community Health Survey-Mental Health, this secondary analysis aimed to determine the prevalence of perceived prejudice by health care providers (HCPs) and its relationship with mental disorders. Respondents accessing HCPs in the prior year were asked if they experienced HCP prejudice. A hypothesis driven multivariable logistic regression analysis was conducted to determine the relationship between type of mental disorders and HCP prejudice. Among the 3006 respondents, 10.9 % perceived HCP prejudice, 62.4 % of whom reported a mental disorder. The adjusted odds of prejudice was highest for respondents with anxiety (OR 3.12; 95 % CI 1.60, 6.07), concurrent mood or anxiety and substance disorders (OR 3.08; 95 % CI 1.59, 5.95) and co-occurring mood and anxiety disorders (OR 2.89; 95 % CI 1.68, 4.97) compared to respondents without any mental disorders. These findings are timely for informing discussions regarding policies to address HCP prejudice towards people with mental disorders.

  9. Relationship between signal intensity of blood flow in the pulmonary artery obtained by magnetic resonance imaging and results of right cardiac catheterization in patients with pulmonary disease

    Electrocardiogram-gated spin-echo magnetic resonance (MR) images of the chest were obtained in five normal controls and 35 patients with pulmonary disease (11 chronic obstructive pulmonary disease, 6 pulmonary thromboembolism, 5 primary pulmonary hypertension, 4 interstitial pulmonary disease, 4 pulmonary hypertension with disturbance of portal circulation, and 5 other diseases) who underwent right cardiac catheterization. In transverse images at the level of the right main pulmonary artery (rPA) and sagittal images at the level through the midsternal line and the spinal cord, the signal intensity of blood flow in the rPA was quantitatively evaluated, and the correlations with the MR signal intensity of intravascular flow and the parameters of hemodynamics were studied. In diastole MR images of both normal controls and patients mostly showed a significant signal and visible flow images. In systolic MR images, the mean values of hemodynamic parameters (mean pulmonary arterial pressure (mPAP), pulmonary arteriolar resistance (PAR), and cardiac index (CI)) were abnormal in patients with significant signal intensity of flow compared with those in patients without sufficient MR signal. The signal intensity was not correlated with mPAP; however, it significantly increased as PAR increased, and it increased as CI decreased both in diastole and in systole. Especially in systole, there was good correlation between the signal intensity in transverse MR images and CI and between signal intensity in sagittal MR images and PAR . These results suggest that the signal intensity of blood flow in the rPA on MR images can be used as an index of the severity of right heart failure associated with pulmonary disease. MR imaging is a useful modality to evaluate pulmonary circulation disturbance because of its ability to assess blood flow in the pulmonary artery noninvasively without interference from other structures such as bone and normal lung.

    Few studies have investigated the 24-hour symptom profile in patients with COPD or how symptoms during the 24-hour day are inter-related. This observational study assessed the prevalence, severity and relationship between night-time, early morning and daytime COPD symptoms and explored the relationship between 24-hour symptoms and other patient-reported outcomes. The study enrolled patients with stable COPD in clinical practice. Baseline night-time, early morning and daytime symptoms (symptom questionnaire), severity of airflow obstruction (FEV1), dyspnoea (modified Medical Research Council Dyspnoea Scale), health status (COPD Assessment Test), anxiety and depression levels (Hospital Anxiety and Depression Scale), sleep quality (COPD and Asthma Sleep Impact Scale) and physical activity level (sedentary, moderately active or active) were recorded. The full analysis set included 727 patients: 65.8% male, mean ± standard deviation age 67.2 ± 8.8 years, % predicted FEV1 52.8 ± 20.5%. In each part of the 24-hour day, >60% of patients reported experiencing ≥1 symptom in the week before baseline. Symptoms were more common in the early morning and daytime versus night-time (81.4%, 82.7% and 63.0%, respectively). Symptom severity was comparable for each period assessed. Overall, in the week before baseline, 56.7% of patients had symptoms throughout the whole 24-hour day (3 parts of the day); 79.9% had symptoms in ≥2 parts of the 24-hour day. Symptoms during each part of the day were inter-related, irrespective of disease severity (all p < 0.001). Early morning and daytime symptoms were associated with the severity of airflow obstruction (p < 0.05 for both). Night-time, early morning and daytime symptoms were all associated with worse dyspnoea, health status and sleep quality, and higher anxiety and depression levels (all p < 0.001 versus patients without symptoms in each corresponding period). In each part of the 24-hour day, there was also an association between

    Recent increases in obesity prevalence have led to research into the neighbourhood food environment. Research suggests that proximity and density of food outlets around the home is associated with childhood obesity prevalence, however, the evidence is inconclusive, and associations between food outlet locations and diet are less clear. The purpose of this study is to assess area level associations between sales of unhealthy foods in supermarkets and weight status of children. This study examined the association between weight status in children (4-5 year olds and 10-11 year olds) measured in the National Child Measurement Programme over three time points (2008/9, 2009/10, 2010/11) and annual sales of unhealthy foods (2012/3), as identified from a large supermarket chain. Geographical analysis was conducted to link store-based food sales for 537 stores with 6517 UK Census Areas. Unadjusted associations were examined with error-bar plots and linear regression was used to examine the relationship between the prevalence of overweight and obesity and sales of unhealthy food, while controlling for covariates known to predict weight status in children. A statistically significant relationship was identified between the sales of unhealthy foods and the prevalence of overweight and obese children in both age groups (p sales with the weight status of children. Food sales in geographically referenced supermarkets are a valuable source of data for research into the factors that influence the weight of the surrounding population. Future research could identify factors that might modify food shopping in supermarkets and use of purchasing data could be an effective way to measure the impact of healthy eating campaigns on the weight status of children over time.

    Studies based on the ISAAC questionnaire suggest a correlation between the use of antibiotics and the prevalence of asthma and allergy in children aged 6-7 years. The number of courses of antibiotic therapy is an important factor. To investigate the relationship between the use of antibiotics during the first years of life and the prevalence of allergy and asthma among children (aged 6-8 years) in the urban population of Poland. A survey-based study with a self-completed questionnaire. The respondents were parents of children aged 6-8 years living in Warszawa, Poland. 1461 completed questionnaires were collected. Asthma was declared in 4.3% of the children. Wheezing and/or sibilant rhonchi within 12 months before the study was observed in 13.5% of the cases. Asthma medication was taken by 21.8% of the children. Allergic rhinitis was declared in 18.7% of the children. Problems with sneezing, rhinorrhea, and nasal congestion not associated with cold or fever were observed in 40.7% of the children. The analysis of the odds ratios between the use of antibiotics and the symptoms of allergic diseases revealed a clear correlation. The highest odds ratio was observed between the completion of over three courses of antibiotic therapy prior to the age of 12 months and the declaration of one of the following: asthma (OR = 5.59, 95% CI: 2.6-12.01), wheezing and/or sibilant rhonchi (OR = 4.68, 95% CI: 3.01-7.27) and taking medicines for breathlessness (OR = 5.12, 95% CI: 3.42-7.68). There is a direct relationship between antibiotic use in the first 3 years of life and asthma and allergy symptoms in children aged 6-8 years old.

    Predicting changes in forested seasonal snowpacks under altered climate scenarios is one of the most pressing hydrologic challenges facing today's society. Airborne- and satellite-based remote sensing methods hold the potential to transform measurements of terrestrial water stores in snowpack, improve process representations of snowpack accumulation and ablation, and to generate high quality predictions that inform potential strategies to better manage water resources. While the effects of forest on snowpack are well documented, many of the fine-scale processes influenced by the forest-canopy are not directly accounted for because most snow models don't explicitly represent canopy structure and canopy heterogeneity. This study investigates the influence of forest canopy on snowpack distribution at fine scales and quantifies the influence of canopy heterogeneity on snowpack accumulation and ablation processes. We use terrestrial laser scanning (TLS) data collected during the SnowEX campaign to discover how the relationships between canopy and snow distributions change across scales. Our sample scales range from individual trees to patches of trees across the Grand Mesa, CO, SnowEx site.

    Full Text Available International Boat Show, a business and tourist event, has been held annually in Italian city of Genoa since 1962. The fair is one of the oldest, largest and best known in the field of boating industry worldwide, primarily due to good management of the event and it can serve as case study for domestic fair organizers to improve the quality of their business and services. Since Belgrade is the city of fairs, but compared to Genoa still underdeveloped in terms of trade shows, the following tasks imposed naturally in this study: to determine the relationship of the organizers of Genoa Boat Show in the sector of preparation and fair offer, in the sector of selection and communication with specific target groups (especially visitors, services during the fair and functioning of the city during the fair. During the research the authors have mostly used historical method, comparison, synthesis and the interview method. The results of theoretical research, in addition, may help not only managers of fair shows and of exhibitions, but also to organizers of other events in our country

    Research into workplace mentoring is primarily focused on the experiences and perceptions of individuals involved in the relationship, while there is scarcely any research focusing on the impact of mentoring relationships on their social environment. This exploratory research aims to give insight into how coworkers’ perceptions and experiences of informal mentoring relationships in their workgroup are related to their perceptions of workgroup functioning. The results of 21 semistructured interviews show that coworkers believe that mentoring relationships affect their workgroup’s functioning by influencing both their workgroup’s performance and climate. Coworkers applied an instrumental perspective and described how they think that mentoring relationships both improve and hinder their workgroup’s performance as they influence the individual functioning of mentor and protégé, the workgroup’s efficiency, and organizational outcomes. Furthermore, coworkers applied a relational perspective and described how mentoring relationships may influence their workgroup’s climate in primarily negative ways as they may be perceived as a subgroup, cause feelings of distrust and envy, and are associated with power issues. The results of this study emphasize the importance of studying mentoring relationships in their broader organizational context and set the groundwork for future research on mentoring relationships in workgroups.

    This study aims to examine whether (a) low child valence (emotional connectedness) within the mother-child relationship increases the risk for offspring depression, (b) low child potency (individual autonomy) increases the risk for offspring anxiety, and (c) maternal psychopathology pronounces these associations. We used data from a prospective-longitudinal study of adolescents (aged 14-17 at baseline) and their mothers (N = 1,015 mother-child dyads). Anxiety disorders and depression were assessed repeatedly over 10 years in adolescents (T0, T1, T2, T3) and their mothers (T1, T3) using the DSM-IV/M-CIDI. Valence and potency were assessed in mothers (T1) with the Subjective Family Image Questionnaire. Odds ratios (OR) from logistic regression were used to estimate associations between low child valence/potency and offspring psychopathology (cumulated lifetime incidences; adjusted for sex and age). In separate models (low valence or low potency as predictor), low child valence predicted offspring depression only (OR = 1.26 per SD), while low child potency predicted offspring anxiety (OR = 1.24) and depression (OR = 1.24). In multiple models (low valence and low potency as predictors), low child valence predicted offspring depression only (OR = 1.19), while low child potency predicted offspring anxiety only (OR = 1.22). Low child potency interacted with maternal anxiety on predicting offspring depression (OR = 1.49), i.e. low child potency predicted offspring depression only in the presence of maternal anxiety (OR = 1.33). These findings suggest that low child valence increases the risk for offspring depression, while low child potency increases the risk for offspring anxiety and depression and interacts with maternal psychopathology on predicting offspring depression.

    Adults with Down syndrome (DS) represent an enriched population for the development of Alzheimer's disease (AD), which could aid the study of therapeutic interventions, and in turn, could benefit from discoveries made in other AD populations. 1) Understand the relationship between tau pathology and age, amyloid deposition, neurodegeneration (MRI and FDG PET), and cognitive and functional performance; 2) detect and differentiate AD-specific changes from DS-specific brain changes in longitudinal MRI. Twelve non-demented adults, ages 30 to 60, with DS were enrolled in the Down Syndrome Biomarker Initiative (DSBI), a 3-year, observational, cohort study to demonstrate the feasibility of conducting AD intervention/prevention trials in adults with DS. We collected imaging data with 18F-AV-1451 tau PET, AV-45 amyloid PET, FDG PET, and volumetric MRI, as well as cognitive and functional measures and additional laboratory measures. All amyloid negative subjects imaged were tau-negative. Among the amyloid positive subjects, three had tau in regions associated with Braak stage VI, two at stage V, and one at stage II. Amyloid and tau burden correlated with age. The MRI analysis produced two distinct volumetric patterns. The first differentiated DS from normal (NL) and AD, did not correlate with age or amyloid, and was longitudinally stable. The second pattern reflected AD-like atrophy and differentiated NL from AD. Tau PET and MRI atrophy correlated with several cognitive and functional measures. Tau accumulation is associated with amyloid positivity and age, as well as with progressive neurodegeneration measurable using FDG and MRI. Tau correlates with cognitive decline, as do AD-specific hypometabolism and atrophy.

    Bali karena berimplikasi positif pada ekonomi para pihak terkait, pengayaan bagi seni pertunjukan daerah setempat, dan identitas bagi kawasan wisata Nusa Dua, Bali. This article was compiled from the research results that aimed to understand the Davedan Show at Amphi Theater Nusa Dua, Bali. This research was conducted due to the imbalance between the assumption and the reality in real life. Generally, tourists visiting Bali are more excited and enthusiastic to watch the tourism performing arts that are based on local traditional art and culture. However, the reality is different. The questions are: how is the form of the Davedan show?; why do the tourists enjoy watching the show ?; what are the implications for the performer, the society, and the tourism industry in Nusa Dua, Bali?. This research applied qualitative research methods, especially the participative implementation that prioritized cooperation between the researchers and the related informants. The data sources of the research were the Davedan show, management, dancers, audiences, and similar research results produced by previous researchers. All data that had been collected by observation, interview, FGD, and literature study were then analyzed with aesthetic postmodern theory, theory of practice, and theory of power relationship. The results showed that: (1 Davedan Show was presented with the concept of a new presentation in the tourism performing arts in Bali. It could be seen from the material, the form, the way of presentation, and the management of the show. Davedan Show, presenting the theme of Treasure of the Archipelago and opening the new adventure gate, was accompanied by ethnic music recordings of the archipelago in a medley then continued with the performance structures of: Balinese, Sumatran, Sundanese, Solo, Borneo and Papuan art and culture; (2 Davedan Show attracted many foreign tourists because the show was based on the existence of market, aesthetic, and cultural ideologies of the

    trust was associated with lower all-cause mortality rates and that association varied by race/ethnicity within the male-to-male and IDU transmission groups only. Social trust may promote timely HIV testing, which can facilitate earlier HIV diagnosis, thus it can be a useful determinant to monitor the relationship with HIV care continuum outcomes especially for racial/ethnic minority groups disproportionately infected by HIV.

    This study examined the prevalence of a history of various combinations of childhood maltreatment types (physical abuse, sexual abuse, and witnessing of maternal battering) among adult members of a health maintenance organization (HMO) and explored the relationship with adult mental health of the combinations of types of childhood maltreatment and emotional abuse in the childhood family environment. A total of 8,667 adult members of an HMO completed measures of childhood exposure to family dysfunction, which included items on physical and sexual abuse, witnessing of maternal battering, and emotional abuse in the childhood family environment. The adults' current mental health was assessed by using the mental health scale of the Medical Outcomes Study 36-item Short-Form Health Survey. The prevalences of sexual abuse, physical abuse, and witnessing of maternal violence were 21.6%, 20.6%, and 14.0%, respectively, when the maltreatment types were considered separately. Among respondents reporting any of the maltreatment types, 34.6% reported more than one type of maltreatment. Lower mean mental health scores were associated with higher numbers of abuse categories (mean=78.5, 75.5, 72.8, and 69.9 for respondents with no, one, two, and three abuse types, respectively). Both an emotionally abusive family environment and the interaction of an emotionally abusive family environment with the various maltreatment types had a significant effect on mental health scores. Childhood physical and sexual abuse, as well as witnessing of maternal battering, were common among the adult members of an HMO in this study. Among those reporting any maltreatment, more than one-third had experienced more than one type of maltreatment. A dose-response relation was found between the number of types of maltreatment reported and mental health scores. In addition, an emotionally abusive family environment accentuated the decrements in mental health scores. Future research examining the effects of

    "The public" is not homogenous and no single message or form of messaging will connect the entire public with the geosciences. One approach to promoting trust in, and engagement with, the geosciences is to identify specific sectors of the public and then develop interactions and communication products that are immediately relevant to that sector's interests. If the content and delivery are appropriate, this approach empowers people to connect with the geosciences on their own terms and to understand the relevance of the geosciences to their own situation. Federal policy makers are a distinct and influential subgroup of the general public. In preparation for the 2016 presidential election, the American Geosciences Institute (AGI) in collaboration with its 51 member societies prepared Geoscience for America's Critical Needs: Invitation to a National Dialogue, a document that identified major geoscience policy issues that should be addressed in a national policy platform. Following the election, AGI worked with eight other geoscience societies to develop Geoscience Policy Recommendations for the New Administration and the 115th Congress, which outlines specific policy actions to address national issues. State and local decision makers are another important subgroup of the public. AGI has developed online content, factsheets, and case studies with different levels of technical complexity so people can explore societally-relevant geoscience topics at their level of technical proficiency. A related webinar series is attracting a growing worldwide audience from many employment sectors. Partnering with government agencies and other scientific and professional societies has increased the visibility and credibility of these information products with our target audience. Surveys and other feedback show that these products are raising awareness of the geosciences and helping to build reciprocal relationships between geoscientists and decision makers.

    This study evaluated the impact of a relationship education program, delivered as part of a college course, among students (N = 152) who reported experiencing psychological aggression in their exclusive dating relationship. Preliminary results showed that compared to those in the control group, participants receiving relationship education were significantly more likely to end their romantic relationship, even after controlling for relationship satisfaction. Furthermore, when relationship termination occurred, those in the intervention group were significantly more likely to attribute the breakup to their participation in the class as compared to those in the control group. The tentative findings are an important preliminary step in assessing the benefits of relationship education in reducing the risk of psychological aggression among college students.

    Unemployment has numerous negative consequences for health, but the family and the welfare state can mitigate these consequences. How the family supports its members and whether and to what extent this interacts with the broader context is still an open question. Our evidence show that job loss is causally linked to significant declines in health for men, but not for women. Yet, the increased risk of poor health is lower for coupled men, especially if the partner is employed. This suggests that both emotional and economic support play a role. Moreover, the family's mitigating role widely varies across different welfare regimes in Europe and it is particularly strong in Southern and Eastern regimes, characterized by "rudimentary" welfare systems and a more traditional family model.

    In this study the authors investigated the neck pain of patients with cervical myelopathy by using a visual analog scale (VAS) before and after laminoplasty, and they analyzed the association of amount of neck pain with the clinical results. A retrospective review was conducted in 41 patients with cervical myelopathy who underwent cervical laminoplasty. The patients were assessed using questionnaires to evaluate the neck pain intensity before surgery, and 2 years after surgery, the outcome was assessed using a VAS. The degree of cervical lordosis and range of motion (ROM) of the cervical spine were evaluated before and after laminoplasty. The neurological status was also evaluated before and after surgery. The patients were classified into 2 groups according to their preoperative neck pain: 1) the pain (PA) group, which included patients whose preoperative VAS score was more than 1 mm; and 2) the no pain (NP) group, which included patients whose preoperative VAS score was 0 mm. Inclusion in the PA group indicated a restriction of the cervical ROM before laminoplasty; however, the improvement of neck pain in this group and the deterioration of pain status in the NP group eliminated this difference after laminoplasty. Thereafter, the PA group was classified into 2 subgroups according to the improvement of the preoperative neck pain: 1) the improved group, which included patients whose postoperative VAS score decreased; and 2) the no improvement group, which included patients who were not in the improved group. No significant differences were observed in the average recovery and radiographic results between these 2 subgroups. Neck pain before surgery in the PA group indicated a restriction of the cervical ROM; however, the improvement of neck pain in this group and the deterioration of pain status in the NP group indicated the disappearance of this difference postoperatively. Moreover, improvement of preoperative neck pain was not associated with the radiographic

    A Web-based survey was conducted to study the religious and health practices, medical history and psychological characteristics among Buddhist practitioners. This report describes the development, advertisement, administration and preliminary results of the survey. Over 1200 Buddhist practitioners responded. Electronic advertisements were the most effective means of recruiting participants. Survey participants were mostly well educated with high incomes and white. Participants engaged in Buddhist practices such as meditation, attending meetings and obtaining instruction from a monk or nun, and practiced healthful behaviors such as regular physical activity and not smoking. Buddhist meditative practice was related to psychological mindfulness and general health.

    To evaluate the CT and MRI findings of the large endolymphatic duct or sac syndrome (LEDS) and its associated anomalies, with clinical features. We retrospectively reviewed the MR and CT images of 52 ears obtained from 26 patients with LEDS. We reviewed the clinical findings, audiology testing, and treatment results. The degree of hearing loss was classified from normal to profound, based on pure tone audiometry. The largest areas were measured at each endolymphatic duct and analyzed to determine whether a correlation exists with the degree of hearing loss. We also analyzed the differences in measurements between CT and MRI findings. All 26 patients had some degree of sensorineural hearing loss, which resulted in 18 ears to undergo a cochlear implantation. One patient was diagnosed with Cornelia de Lange syndrome. Five patients had a sudden hearing loss onset. Ten ears had incomplete cochlear partitions, whereas 28 ears had enlarged vestibules. All patients had severe to profound hearing loss. We found no statistical correlation between the size of the largest area of the endolymphatic duct and the degree of hearing loss. The mean area of the endolymphatic ducts, as per an MRI examination, revealed slightly greater areas than the CT findings, although the differences were not significant.

    Full Text Available Background: Post-menopausal hemorrhage is one of the most common complains in gynecologic clinics. More than 60% of these cases have abnormal findings in diagnostic work ups. There is contraversy about the best diagnostic method for evaluating post-menopausal hemorrhage. The aim of this study was to evaluate the results of Trans-Vaginal Ultrasonography and compare its result to ones derived from direct endometrial biopsy and Hysteroscopy findings.Methods: In a cross-sectional study, menopausal women who attended the outpatient clinic of Arash Hospital, Tehran University of medical Sciences, from April 2005 to March 2006 with the complain of hemorrhage were evaluated. In all of these patients, after getting informed consent, Trans-Vaginal Ultrasonography, Dilatation and Curettage and Hysteroscopy were performed.Results: The total number of 90 women was recruited to the study with the age range of 41-80 years. The mean age of participants was 53.84 ± 6 years and 4.3 ± 5.1 years had passed from their menopause. The mean thickness of endometrium, measured by Trans Vaginal ultrasonography was 6.25 ± 3.7 millimeter. In the biopsy derived specimens, the most finding pathological presentation was atrophy (48.9% and the Proliferative endometrium had the second prevalence (36.7%. Atrophy (44.4% and Proliferative endometrium (33.3% were the most prevalent finding in Hysteroscopy. There was a significant difference in endometrial thickness between groups of different pathological findings. A significant difference in endometrial thickness was also seen between groups with different Hysteroscopic finding. By grouping the data according to endometrial thickness, it became evident that endometrial thickness can predict the outcome of endometrial biopsy and Hysteroscopic finding efficiently. We used ROC curves to find the best grouping threshold for endometrial thickness to achieve the best sensitivity and specificity.Conclusion: Measuring the endometrial

    The objectives of this analysis were to examine how patients' global severity with Alzheimer's disease (AD) relates to costs of care and explore the incremental effects of global severity measured by the clinical dementia rating (CDR) scale on these costs for patients in Spain. The Codep-EA study is an 18-multicenter, cross-sectional, observational study among patients (343) with AD according to the CDR score and their caregivers in Spain. The data obtained included (in addition to clinical measures) also socio-demographic data concerning the patient and its caregiver. Cost analyses were based on resource use for medical care, social care, caregiver productivity losses, and informal caregiver time reported in the resource utilization in dementia (RUD). Lite instrument and a complementary questionnaire. Multivariate regression analysis was used to model the effects of global severity and other socio-demographic and clinical variables on cost of care. The mean (standard deviation) costs per patient over 6 months for direct medical, social care, indirect and informal care costs, were estimated at €1,028.1 (1,655.0), €843.8 (2,684.8), €464.2 (1,639.0) and €33,232.2 (30,898.9), respectively. Dementia severity, as having a CDR score 0.5, 2, or 3 with CDR score 1 being the reference group were all independently and significantly associated with informal care costs. Whereas having a CDR score of 2 was also significantly related with social care costs, a CDR score of 3 was associated with most cost components including direct medical, social care, and total costs, all compared to the reference group. The costs of care for patients with AD in Spain are substantial, with informal care accounting for the greatest part. Dementia severity, measured by CDR score, showed that with increasing severity of the disease, direct medical, social care, informal care and total costs augmented.

This study aimed to determine the prevalence of childhood trauma in patients in the UK Early Intervention Service based on a case note review.Methods: This is a retrospective case note study of 296 patients in an UK Early Intervention Service. Trauma history obtained on service entry was reviewed and trauma experienced categorized. Results were analyzed using crosstab and frequency analysis.Results: The mean age of the sample was 24 years, 70% were male, 66% were White, and 23% Asian (ethnicity not documented in 11% of the sample. Approximately 60% of patients reported childhood trauma, 21% reported no childhood trauma, and data were not recorded for the remaining 19%. Among those reporting trauma, the prevalence of most frequently reported traumas were: severe or repeated disruption (21%, parental mental illness (19%, bullying (18%, absence of a parent (13%, and ‘other’ trauma (24% – the majority of which were victimization events. Sixty-six percent of those reporting trauma had experienced multiple forms of trauma.Conclusion: A high prevalence of childhood trauma (particularly trauma related to the home environment or family unit was reported. This is consistent with other studies reporting on trauma and psychosis. The main weakness of the study is a lack of a control group reporting experience of childhood trauma in those without psychosis. Guidelines recommend that all patients with

    The Geospatial Determinants of Health Outcomes Consortium (GeoDHOC) study investigated ambient air quality across the international border between Detroit, Michigan, USA and Windsor, Ontario, Canada and its association with acute asthma events in 5- to 89-year-old residents of these cities. NO2, SO2, and volatile organic compounds (VOCs) were measured at 100 sites, and particulate matter (PM) and polycyclic aromatic hydrocarbons (PAHs) at 50 sites during two 2-week sampling periods in 2008 and 2009. Acute asthma event rates across neighborhoods in each city were calculated using emergency room visits and hospitalizations and standardized to the overall age and gender distribution of the population in the two cities combined. Results demonstrate that intra-urban air quality variations are related to adverse respiratory events in both cities. Annual 2008 asthma rates exhibited statistically significant positive correlations with total VOCs and total benzene, toluene, ethylbenzene and xylene (BTEX) at 5-digit zip code scale spatial resolution in Detroit. In Windsor, NO2, VOCs, and PM10 concentrations correlated positively with 2008 asthma rates at a similar 3-digit postal forward sortation area scale. The study is limited by its coarse temporal resolution (comparing relatively short term air quality measurements to annual asthma health data) and interpretation of findings is complicated by contrasts in population demographics and health-care delivery systems in Detroit and Windsor.

Age, gender, and trust in the GP were not significant predictors for either willingness to undergo online treatment or to pay additionally for online treatment. Willingness to undergo online treatment was partly determined by the actual use of online communication with the GP, willingness to communicate online with the GP, health information-seeking personality, and social motivation for such behavior. Willingness to pay extra for online treatment was influenced by the monthly household net income category and education level. The results of this study are useful for online health care providers and physicians who are considering offering online treatments as a viable number of patients would appreciate the possibility of undergoing an online treatment offered by their GP.

  4. Myopes show increased susceptibility to nearwork aftereffects.

    1998-09-01

    Some aspects of accommodation may be slightly abnormal (or different) in myopes, compared with accommodation in emmetropes and hyperopes. For example, the initial magnitude of accommodative adaptation in the dark after nearwork is greatest in myopes. However, the critical test is to assess this initial accommodative aftereffect and its subsequent decay in the light under more natural viewing conditions with blur-related visual feedback present, if a possible link between this phenomenon and clinical myopia is to be considered. Subjects consisted of adult late- (n = 11) and early-onset (n = 13) myopes, emmetropes (n = 11), and hyperopes (n = 9). The distance-refractive state was assessed objectively using an autorefractor immediately before and after a 10-minute binocular near task at 20 cm (5 diopters [D]). Group results showed that myopes were most susceptible to the nearwork aftereffect. It averaged 0.35 D in initial magnitude, with considerably faster posttask decay to baseline in the early-onset (35 seconds) versus late-onset (63 seconds) myopes. There was no myopic aftereffect in the remaining two refractive groups. The myopes showed particularly striking accommodatively related nearwork aftereffect susceptibility. As has been speculated and found by many others, transient pseudomyopia may cause or be a precursor to permanent myopia or myopic progression. Time-integrated increased retinal defocus causing axial elongation is proposed as a possible mechanism.

    Full Text Available This study investigated a key claim of risk regulation theory, namely, that psychological internalizing of a relationship threat will serve as a mediator of the link between self-models (self-esteem and attachment anxiety and relationship responses (moving closer to a partner vs. distancing from a partner. Participants (N = 101 received feedback that threatened their current romantic relationship (or no feedback and then completed measures of internal–external focus, relationship closeness–distancing, and acceptance–rejection of the feedback. Results showed that participants with negative self-models responded to the relationship threat by becoming more internally focused and by distancing from their partners, whereas those with positive self-models became more externally focused and moved closer to their partners. Mediation analyses indicated that the link between self-models and relationship closeness–distancing was partially explained by internal focus.

    The American Museum of Natural History's Hayden Planetarium was rebuilt in year 2000 as an immersive theater for scientific data visualization to show the universe in context to our planet. Specific astrophysical movie productions provide the main daily programming, but interactive control software, developed at AMNH allows immersive presentation within a data aggregation of astronomical catalogs called the Digital Universe 3D Atlas. Since 2006, WMS globe browsing capabilities have been built into a software development collaboration with Sweden's Linkoping University (LiU). The resulting Uniview software, now a product of the company SCISS, is operated by about fifty planetariums around that world with ability to network amongst the sites for global presentations. Public presentation of NASA GIBS has allowed authoritative narratives to be presented within the range of data available in context to other sources such as Science on a Sphere, NASA Earth Observatory and Google Earth KML resources. Specifically, the NOAA supported World Views Network conducted a series of presentations across the US that focused on local ecological issues that could then be expanded in the course of presentation to national and global scales of examination. NASA support of for GIBS resources in an easy access multi scale streaming format like WMS has tremendously enabled particularly facile presentations of global monitoring like never before. Global networking of theaters for distributed presentations broadens out the potential for impact of this medium. Archiving and refinement of these presentations has already begun to inform new types of documentary productions that examine pertinent, global interdependency topics.

  10. FRANCHISOR-FRANCHISEE RELATIONSHIP QUALITY: TIME OF RELATIONSHIP AND PERFORMANCE

    Luís Fernando Varotto

    2016-11-01

    Full Text Available Franchise literature disputes how the relationship between franchisors and franchisees develops over time. Traditional lifecycle theory views relationships following an ascendant curve, in which relationship quality and performance strengthen over time. Another perspective better reflects the peculiarities of the franchisor-franchisee relationship, indicating that relationship quality in franchise systems follows a U-shaped curve. There is also limited research on the moderating effect of time on the relationship between relational variables and outcomes. This study sheds light on the influence of relationship duration on relationship quality and financial performance in the franchisee-franchisor relationship. Using a self-report survey from a sample of 342 franchisees, mean and regression analyses are conducted to test relationships. Results confirm the time effect on franchisor-franchisee relationship quality and performance, but the hypothesized shape of relationship phases is only partially confirmed. Moreover, time has a positive moderating effect on the impact of relationship quality on financial performance.

    cells of unknown significance (ASCUS or low-grade squamous intraepithelial lesions (LSIL. METHODS: a cross-sectional study comprising 161 women referred to the Taubaté University Hospital due to ASCUS/LSIL, between August 2000 and September 2002. All women responded to a questionnaire regarding sociodemographic and reproductive characteristics and were subjected to gynecological examination with specimen collection for Pap test and HCII, along with colposcopy and eventual cervical biopsy. The relationship between HCII results and age, use of condom, oral hormonal contraception, and smoking were evaluated by the chi-square test. The sensitivity, specificity, positive and negative predictive values of both Pap test and HCII were calculated. All calculations were performed within 95% confidence intervals. RESULTS: sixty-seven percent of the women that tested positive for HPV were less than 30 years old. Pap smear and HCII showed the same 82% sensitivity in detecting CIN2/3 when the threshold for a positive Pap result was ASCUS, LSIL or HSIL. Pap smear specificity and positive predictive values were substantially increased when only HSIL results were considered as positive (from 29 to 95% and 12 to 50%, respectively. These figures were superior to those of HCII, but at the expense of an expressive loss of sensitivity (from 82% to 41%. CONCLUSIONS: our results substantiate the potential of HCII in detecting CIN2/3 among women referred due to ASCUS/LSIL.

    To see if patient satisfaction with psychotropics (PSP) could be used as a patient-oriented outcome variable in the evaluation of PSP drugs in clinical epidemiological studies, relationships between PSP, clinical status, QoL, compliance and the type of antipsychotic were analyzed. Elements of validation of PSP were also assessed. In a 6-month prospective study, 933 schizophrenic outpatients with initiation or change to their antipsychotic treatment were enrolled. Psychiatrists completed five CGI-SCH scales (positive, negative, cognitive, depressive and global), hospitalization, compliance, and prescription variables. Patients completed PSP, EuroQoL scales, sexual function and compliance variables. A satisfactory structural equation model was obtained showing significant relationships PSP/compliance (coef.=0.16), QoL/PSP (coef.=0.37), clinical status/QoL (coef.=0.61), clinical status/compliance (coef.=0.09). Patients receiving olanzapine were more satisfied than patients receiving other atypicals (coef.=012) and had better clinical status than patients treated with typicals (coef.=0.08). Evolution of PSP was related to clinical status, QoL, and continuation of treatment (all Pmeasure was not sufficiently sensitive to change. Multi-item questionnaires evaluating different dimensions are needed.

    The question of whether physical activity is associated with positive aspects of health becomes increasingly more important in the light of the health status in today's children and adolescents and due to the changing lifestyle with respect to everyday activity. The German Health Interview and Examination Survey for Children and Adolescents (KiGGS) collected the first set of nationwide representative cross-sectional data to examine the relationship between health and physical activity. Taking sociodemographic parameters into consideration, the results suggest a positive association between self-estimated general health and several types of physical activity. The results vary with respect to gender and type of physical activity. For methodological reasons, causal conclusions can only be drawn after longitudinal data of the second wave of KiGGS are available.

    The poster presented will give an overview of a study towards a "Space Road Show". The topic of this show is space science. The target group is adolescents, aged 12 to 15, at Dutch high schools. The show and its accompanying experiments would be supported with suitable educational material. Science teachers at schools can decide for themselves if they want to use this material in advance, afterwards or not at all. The aims of this outreach effort are: to motivate students for space science and engineering, to help them understand the importance of (space) research, to give them a positive feeling about the possibilities offered by space and in the process give them useful knowledge on space basics. The show revolves around three main themes: applications, science and society. First the students will get some historical background on the importance of space/astronomy to civilization. Secondly they will learn more about novel uses of space. On the one hand they will learn of "Views on Earth" involving technologies like Remote Sensing (or Spying), Communication, Broadcasting, GPS and Telemedicine. On the other hand they will experience "Views on Space" illustrated by past, present and future space research missions, like the space exploration missions (Cassini/Huygens, Mars Express and Rosetta) and the astronomy missions (Soho and XMM). Meanwhile, the students will learn more about the technology of launchers and satellites needed to accomplish these space missions. Throughout the show and especially towards the end attention will be paid to the third theme "Why go to space"? Other reasons for people to get into space will be explored. An important question in this is the commercial (manned) exploration of space. Thus, the questions of benefit of space to society are integrated in the entire show. It raises some fundamental questions about the effects of space travel on our environment, poverty and other moral issues. The show attempts to connect scientific with

    2015-01-01

    Background Many studies have shown that women use the Internet more often for health-related information searches than men, but we have limited knowledge about the underlying reasons. We also do not know whether and how women and men differ in their current use of the Internet for communicating with their general practitioner (GP) and in their future intention to do so (virtual patient-physician relationship). Objective This study investigates (1) gender differences in health-related information search behavior by exploring underlying emotional, motivational, attitudinal as well as cognitive variables, situational involvement, and normative influences, and different personal involvement regarding health-related information searching and (2) gender differences in the virtual patient-physician relationship. Methods Gender differences were analyzed based on an empirical online survey of 1006 randomly selected German patients. The sample was drawn from an e-panel maintained by GfK HealthCare. A total of 958 usable questionnaires were analyzed. Principal component analyses were carried out for some variables. Differences between men (517/958) and women (441/958) were analyzed using t tests and Kendall’s tau-b tests. The survey instrument was guided by several research questions and was based on existing literature. Results Women were more engaged in using the Internet for health-related information searching. Gender differences were found for the frequency of usage of various Internet channels for health-related information searches. Women used the Internet for health-related information searches to a higher degree for social motives and enjoyment and they judged the usability of the Internet medium and of the information gained by health information searches higher than men did. Women had a more positive attitude toward Web 2.0 than men did, but perceived themselves as less digitally competent. Women had a higher health and nutrition awareness and a greater

    Laser shows and beam effects have been a source of entertainment since its first public performance May 9, 1969, at Mills College in Oakland, California. Since 1997, the Photonics Center, NgeeAnn Polytechnic, Singapore, has been using laser shows as a teaching tool. Students are able to exhibit their creative skills and learn at the same time how lasers are used in the entertainment industry. Students will acquire a number of skills including handling three- phase power supply, operation of cooling system, and laser alignment. Students also acquire an appreciation of the arts, learning about shapes and contours as they develop graphics for the shows. After holography, laser show animation provides a combination of the arts and technology. This paper aims to briefly describe how a krypton-argon laser, galvanometer scanners, a polychromatic acousto-optic modulator and related electronics are put together to develop a laser projector. The paper also describes how students are trained to make their own laser animation and beam effects with music, and at the same time have an appreciation of the operation of a Class IV laser and the handling of optical components.

  7. Do men and women show love differently in marriage?

    2012-11-01

    In Western societies, women are considered more adept than men at expressing love in romantic relationships. Although scholars have argued that this view of love gives short shrift to men's ways of showing love (e.g., Cancian, 1986; Noller, 1996), the widely embraced premise that men and women "love differently" has rarely been examined empirically. Using data collected at four time points over 13 years of marriage, the authors examined whether love is associated with different behaviors for husbands and wives. Multilevel analyses revealed that, counter to theoretical expectations, both genders were equally likely to show love through affection. But whereas wives expressed love by enacting fewer negative or antagonistic behaviors, husbands showed love by initiating sex, sharing leisure activities, and doing household work together with their wives. Overall, the findings indicate that men and women show their love in more nuanced ways than cultural stereotypes suggest.

    Full Text Available Para tener un punto de vista claro y objetivo frente a la polémica establecida en torno al programa “Protagonistas de novela” y la tendiente proliferación de los reality show en las parrillas de programación de la televisión colombiana, se realizó un análisis de texto y contenido de dicho programa, intentando definirlo desde sus posibilidades de realidad, ficción y show. Las unidades de análisis y el estudio de su tratamiento arrojaron un alto contenido que gira en torno a las emociones del ser humano relacionadas con la convivencia, tratadas a manera de show y con algunos aportes textuales de ficción, pero sin su elemento mediador básico, el actor, quitándole toda la posibilidad de tener un tratamiento con la profundidad, distancia y ética que requieren los temas de esta índole. El resultado es un formato que sólo busca altos índices de sintonía y que pertenece más a la denominada televisión “trash”, que a una búsqueda de realidad del hombre y mucho menos de sociedad.

    Here, we report on findings from a 15-month follow-up of a school-based program called Empowering a Multimodal Pathway Toward Healthy Youth (EMPATHY). This was primarily intended to reduce suicidal thinking in pre-teens, adolescents, and youth students aged 11–18 in middle schools (Grades 6–8) and high SCHOOLS (Grades 9–12). It also aimed to reduce depression and anxiety. The EMPATHY multimodal program consisted of repeated data collection, identification of a high-risk group, a rapid intervention for this high-risk group including offering supervised online cognitive behavioral therapy (CBT) program, a universal CBT intervention for those in Grades 6–8, a variety of interactions with trained staff (“Resiliency Coaches”), and referral to external medical and psychiatric services where appropriate. There were four time-points at which assessments were made: baseline, 3, 7, and 15 months. Here, we report cross-sectional findings over 15 months in a total of 6,227 students who were assessed at least once during the study period. Additionally, we report longitudinal findings from the 1,884 students who completed all 4 assessments. Our results found highly statistically significant decreases in suicidality rates, with the percentage of the total school population who were actively suicidal decreasing from 4.4% at baseline (n = 143 of 3,244) to 2.8% at 15 months (n = 125 of 4,496) (p < 0.001). There were also highly statistically significant reductions in depression and anxiety scores at each time-point. Thus, Mean Depression scores at baseline for the entire student population were 3.73 ± 3.87 (n = 3,244) at baseline and decreased to 3.22 ± 3.52 (n = 4,496) (p < 0.001). Since most students were not depressed, whole population changes such as this may indicate impact in many areas. In the longitudinal analysis of students who completed all four assessments, there were also highly statistically significant improvements

  18. Tomato Fruits Show Wide Phenomic Diversity but Fruit Developmental Genes Show Low Genomic Diversity.

    Directory of Open Access Journals (Sweden)

    Vijee Mohan

    Full Text Available Domestication of tomato has resulted in large diversity in fruit phenotypes. An intensive phenotyping of 127 tomato accessions from 20 countries revealed extensive morphological diversity in fruit traits. The diversity in fruit traits clustered the accessions into nine classes and identified certain promising lines having desirable traits pertaining to total soluble salts (TSS, carotenoids, ripening index, weight and shape. Factor analysis of the morphometric data from Tomato Analyzer showed that the fruit shape is a complex trait shared by several factors. The 100% variance between round and flat fruit shapes was explained by one discriminant function having a canonical correlation of 0.874 by stepwise discriminant analysis. A set of 10 genes (ACS2, COP1, CYC-B, RIN, MSH2, NAC-NOR, PHOT1, PHYA, PHYB and PSY1 involved in various plant developmental processes were screened for SNP polymorphism by EcoTILLING. The genetic diversity in these genes revealed a total of 36 non-synonymous and 18 synonymous changes leading to the identification of 28 haplotypes. The average frequency of polymorphism across the genes was 0.038/Kb. Significant negative Tajima'D statistic in two of the genes, ACS2 and PHOT1 indicated the presence of rare alleles in low frequency. Our study indicates that while there is low polymorphic diversity in the genes regulating plant development, the population shows wider phenotype diversity. Nonetheless, morphological and genetic diversity of the present collection can be further exploited as potential resources in future.

    Cultural tourism expanded in the last half of the twentieth century, and the interest of visitors has come to include caves containing archaeological remains. Some show caves attracted mass tourism, and economical interests prevailed over conservation, which led to a deterioration of the subterranean environment and the rock art. The presence and the role of microorganisms in caves is a topic that is often ignored in cave management. Knowledge of the colonisation patterns, the dispersion mechanisms, and the effect on human health and, when present, over rock art paintings of these microorganisms is of the utmost importance. In this review the most recent advances in the study of microorganisms in caves are presented, together with the environmental implications of the findings.

  1. Large-Scale Analysis of Relationships between Mineral Dust, Ice Cloud Properties, and Precipitation from Satellite Observations Using a Bayesian Approach: Theoretical Basis and First Results for the Tropical Atlantic Ocean

    Directory of Open Access Journals (Sweden)

    Lars Klüser

    2017-01-01

    Full Text Available Mineral dust and ice cloud observations from the Infrared Atmospheric Sounding Interferometer (IASI are used to assess the relationships between desert dust aerosols and ice clouds over the tropical Atlantic Ocean during the hurricane season 2008. Cloud property histograms are first adjusted for varying cloud top temperature or ice water path distributions with a Bayesian approach to account for meteorological constraints on the cloud variables. Then, histogram differences between dust load classes are used to describe the impact of dust load on cloud property statistics. The analysis of the histogram differences shows that ice crystal sizes are reduced with increasing aerosol load and ice cloud optical depth and ice water path are increased. The distributions of all three variables broaden and get less skewed in dusty environments. For ice crystal size the significant bimodality is reduced and the order of peaks is reversed. Moreover, it is shown that not only are distributions of ice cloud variables simply shifted linearly but also variance, skewness, and complexity of the cloud variable distributions are significantly affected. This implies that the whole cloud variable distributions have to be considered for indirect aerosol effects in any application for climate modelling.

    2017-07-01

    Parent-adolescent conflicts often comprise the reasons for the referral of adolescents in treatment facilities. However, studies on the effects of behavioral interventions with this indication are rarely published, even in the international literature. In an explorative study, we assessed the efficacy and the acceptance of systemic-behavioral treatment modules of the treatment program for adolescents with disturbances of self-esteem, performance and relationships (SELBST). Ten adolescents aged 12 to 18 years (mean age 14,7 years) and their parents with severe parent-adolescents conflicts according to clinical judgment and with increased parent and adolescent ratings of conflicts on the Conflict-Behavior-Questionnaire-Cologne were included in the study. Analyses of pre to post changes showed a reduction in conflicts and/or an increase in conflict-solving skills as rated by the parents on various outcome measures. However, parents had problems attending the family sessions regularly and to implement therapeutic tasks in the daily family routine which may have limited the effects of the intervention. There is preliminary evidence that SELBST is a useful program for the treatment of parent-adolescent conflicts. To further increase the effectiveness of the program, knowledge from this trial has been considered in the development of the manual.

  3. ODSCC algorithm shows correlation with degradation

    1998-01-01

    Over the last few years we have attempted to develop an algorithm to evaluate the impact of secondary water chemistry on tube degradation in PWR steam generators. Effects of individual factors were assessed and then consolidated to form an algorithm for ODSCC propensity. The algorithm utilizes secondary water chemistry data to calculate ODSCC propensity as a variable named Mega PHI. Prior attempts to correlate algorithm calculations with actual degradation in operating steam generators have resulted in very disappointing results. Recent modifications to the algorithm have demonstrated improved correlation between Mega PHI (calculated result from the algorithm) and actual degradation history from operating plants. The recent modifications involve the inclusion of the synergistic effect of boric acid application of secondary water and of high silica concentration in steam generator toward inhibiting ODSCC. Data from several plants with mill annealed alloy 600 tubing in the steam generators and operating with the primary coolant inlet temperature in the range of 608 to 624 degrees F (320 to 329 degrees C) were evaluated and the results compared with actual degradation reported from in-service inspections. The population of plants includes those with very few tubes repaired and those with hundreds of tubes repaired due to ODSCC at tube support plates. The observation of substantial correlation between the algorithm calculation and actual degradation signifies the roles of boric acid and silica in inhibiting ODSCC. It is recommended that further evaluation of the role of these chemical species be performed using more extensive data. The goal is to modify secondary water chemistry guidelines with the ultimate aim of minimizing corrosion of steam generator tubes. (author)

    The purpose of this pilot study was to assess the impact of media literacy for tobacco prevention for youth delivered through a community site. A randomized pretest-posttest evaluation design with matched-contact treatment and control conditions. The pilot study was delivered through the YMCA in a lower-income suburban and rural area of Southwest Virginia, a region long tied, both economically and culturally, to the tobacco industry. Children ages 8 to 14 (76% white, 58% female) participated in the study (n = 38). The intervention was an antismoking media literacy program (five 1-hour lessons) compared with a matched-contact creative writing control program. General media literacy, three domains of tobacco-specific media literacy ("authors and audiences," "messages and meanings," and "representation and reality"), tobacco attitudes, and future expectations were assessed. Multiple regression modeling assessed the impact of the intervention, controlling for pretest measures, age, and sex. General media literacy and tobacco-specific "authors and audiences" media literacy improved significantly for treatment compared with control (p literacy measures and for tobacco attitudes were not significant. Future expectations of smoking increased significantly for treatment participants ages 10 and younger (p literacy are accompanied by an increase in future expectations to smoke for younger children.

    Full Text Available At the time of our investigation, the CU was not a widespread concept in Argentina, being viewed as a “foreign - far long project” (coming from developed countries and standing for the long term. It is suggested that the rate of CU evolution, in emerging countries like Argentina, is more related to mentality issues than to CU strategic or operative limitations. Although the executives who replied to a survey were not the only power factor in their organization, their comments allow us to think that, in those countries, the CU may have a better future perspective. The research used a quali-quantitative methodology, which was based on a survey to top executives of different kinds of companies located in Argentina. The research design was not experimental and transversal, as it was limited to a specific moment in time.

    Full Text Available Objective : To verify the relationship between intracranial pressure and flash visual evoked potentials (F-VEP in patients with cryptococcal meningitis. Method The sample included adults diagnosed with cryptococcal meningitis admitted at a reference hospital for infectious diseases. The patients were subjected to F-VEP tests shortly before lumbar puncture. The Pearson’s linear correlation coefficient was calculated and the linear regression analysis was performed. Results : Eighteen individuals were subjected to a total of 69 lumbar punctures preceded by F-VEP tests. At the first lumbar puncture performed in each patient, N2 latency exhibited a strong positive correlation with intracranial pressure (r = 0.83; CI = 0.60 - 0.94; p < 0.0001. The direction of this relationship was maintained in subsequent punctures. Conclusion : The intracranial pressure measured by spinal tap manometry showed strong positive association with the N2 latency F-VEP in patients with cryptococcal meningitis.

    Alisky, J; Iczkowski, K; Rapoport, A; Troitsky, N

    1998-01-01

    The emergence of antibiotic-resistant bacteria has prompted interest in alternatives to conventional drugs. One possible option is to use bacteriophages (phage) as antimicrobial agents. We have conducted a literature review of all Medline citations from 1966-1996 that dealt with the therapeutic use of phage. There were 27 papers from Poland, the Soviet Union, Britain and the U.S.A. The Polish and Soviets administered phage orally, topically or systemically to treat a wide variety of antibiotic-resistant pathogens in both adults and children. Infections included suppurative wound infections, gastroenteritis, sepsis, osteomyelitis, dermatitis, empyemas and pneumonia; pathogens included Staphylococcus, Streptococcus, Klebsiella, Escherichia, Proteus, Pseudomonas, Shigella and Salmonella spp. Overall, the Polish and Soviets reported success rates of 80-95% for phage therapy, with rare, reversible gastrointestinal or allergic side effects. However, efficacy of phage was determined almost exclusively by qualitative clinical assessment of patients, and details of dosages and clinical criteria were very sketchy. There were also six British reports describing controlled trials of phage in animal models (mice, guinea pigs and livestock), measuring survival rates and other objective criteria. All of the British studies raised phage against specific pathogens then used to create experimental infections. Demonstrable efficacy against Escherichia, Acinetobacter, Pseudomonas and Staphylococcus spp. was noted in these model systems. Two U.S. papers dealt with improving the bioavailability of phage. Phage is sequestered in the spleen and removed from circulation. This can be overcome by serial passage of phage through mice to isolate mutants that resist sequestration. In conclusion, bacteriophages may show promise for treating antibiotic resistant pathogens. To facilitate further progress, directions for future research are discussed and a directory of authors from the reviewed

    2007-01-01

    Context The relationship between obesity and osteoporosis has been widely studied, and epidemiological evidence shows that obesity is correlated with increased bone mass. Previous analyses, however, did not control for the mechanical loading effects of total body weight on bone mass and may have generated a confounded or even biased relationship between obesity and osteoporosis. Objective To re-evaluate the relationship between obesity and osteoporosis by accounting for the mechanical loading effects of total body weight on bone mass. Methods We measured whole body fat mass, lean mass, percentage fat mass (PFM), body mass index (BMI), and bone mass in two large samples of different ethnicity: 1,988 unrelated Chinese subjects and 4,489 Caucasian subjects from 512 pedigrees. We first evaluated the Pearson correlations among different phenotypes. We then dissected the phenotypic correlations into genetic and environmental components, with bone mass unadjusted, or adjusted, for body weight. This allowed us to compare the results with and without controlling for mechanical loading effects of body weight on bone mass. Results In both Chinese and Caucasians, when the mechanical loading effect of body weight on bone mass was adjusted for, the phenotypic correlation (including its genetic and environmental components) between fat mass (or PFM) and bone mass was negative. Further multivariate analyses in subjects stratified by body weight confirmed the inverse relationship between bone mass and fat mass, after mechanical loading effects due to total body weight was controlled. Conclusions Increasing fat mass may not have a beneficial effect on bone mass. PMID:17299077

  13. Showing Emulsion Properties with Common Dairy Foods

    Bravo-Diaz, Carlos; Gonzalez-Romero, Elisa

    1996-09-01

    Foods are mixtures of different chemical compounds, and the quality we sense (taste, texture, color, etc.) are all manifestations of its chemical properties. Some of them can be visualized with the aid of simple, safe and inexpensive experiments using dairy products that can be found in any kitchen and using almost exclusively kitchen utensils. In this paper we propose some of them related with food emulsions. Food emulsions cover an extremely wide area of daily-life applications such as milk, sauces, dressings and beverages. Experimentation with some culinary recipes to prepare them and the analyisis of the observed results is close to ideal subject for the introduction of chemical principles, allowing to discuss about the nature and composition of foods, the effects of additives, etc. At the same time it allows to get insights into the scientific reasons that underlie on the recipes (something that it is not usually found in most cookbooks). For example, when making an emulsion like mayonnaise, why the egg yolks and water are the first materials in the bowl , and the oil is added to them rather than in the other way around? How you can "rescue" separate emulsions (mayonnaise)? Which parameters affect emulsion stability? Since safety, in its broad sense, is the first requisite for any food, concerns about food exist throughout the world and the more we are aware of our everyday life, the more likely we will be to deal productively with the consequences. On the other hand, understanding what foods are and how cooking works destroys no delightful mystery of the art of cuisine, instead the mystery expands.

  14. Edit propagation using geometric relationship functions

    Guerrero, Paul; Jeschke, Stefan; Wimmer, Michael; Wonka, Peter

    2014-01-01

    We propose a method for propagating edit operations in 2D vector graphics, based on geometric relationship functions. These functions quantify the geometric relationship of a point to a polygon, such as the distance to the boundary or the direction to the closest corner vertex. The level sets of the relationship functions describe points with the same relationship to a polygon. For a given query point, we first determine a set of relationships to local features, construct all level sets for these relationships, and accumulate them. The maxima of the resulting distribution are points with similar geometric relationships. We show extensions to handle mirror symmetries, and discuss the use of relationship functions as local coordinate systems. Our method can be applied, for example, to interactive floorplan editing, and it is especially useful for large layouts, where individual edits would be cumbersome. We demonstrate populating 2D layouts with tens to hundreds of objects by propagating relatively few edit operations. © 2014 ACM 0730-0301/2014/03- ART15 $15.00.

    normal stiffness. This was done because stiffness requires structural weight but ensures freedom from flutter-an uncontrolled, divergent oscillation of the structure, driven by aerodynamic forces and resulting in structural failure. The program used refined theoretical tools to predict at what speed flutter would occur. It then designed a high-response control system to counteract the motion and permit a much lighter wing structure. The wing had, in effect, 'electronic stiffness.' Flight research with this concept was extremely hazardous because an error in either the flutter prediction or control system implementation would result in wing structural failure and the loss of the vehicle. Because of this, flight demonstration of a sub-scale vehicle made sense from the standpoint of both safety and cost. The program anticipated structural failure during the course of the flight research. The Firebee II was a supersonic drone selected as the DAST testbed because its wing could be easily replaced, it used only tail-mounted control surfaces, and it was available as surplus from the U. S. Air Force. It was capable of 5-g turns (that is, turns producing acceleration equal to 5 times that of gravity). Langley outfitted a drone with an aeroelastic, supercritical research wing suitable for a Mach 0.98 cruise transport with a predicted flutter speed of Mach 0.95 at an altitude of 25,000 feet. Dryden and Langley, in conjunction with Boeing, designed and fabricated a digital flutter suppression system (FSS). Dryden developed an RPRV (remotely piloted research vehicle) flight control system; integrated the wing, FSS, and vehicle systems; and conducted the flight program. In addition to a digital flight control system and aeroelastic wings, each DAST drone had research equipment mounted in its nose and a mid-air retrieval system in its tail. The drones were originally launched from the NASA B-52 bomber and later from a DC-130. The DAST vehicle's flight was monitored from the sky by an F

    To evaluate the relationship between tunnel position and widening and long-term clinical results in anterior cruciate ligament (ACL) reconstruction, a retrospective cohort of 30 patients undergoing ACL reconstruction with double semitendinous plus double gracilis (SAC technique) with longer than 10-year follow-up was selected. CT scans in the first 3 months and at final follow-up was evaluated. Position, angle, and widening of tunnels including Nebelung criteria were recorded in all CT scans. Physical, KT-1000, and clinical evaluation were performed at final follow-up. Outcomes and knee arthritis severity were evaluated at final follow-up. Mean follow-up was 11.2 ± 1.2. At final follow-up, 85 and 57% of tibial and femoral tunnels, respectively, developed some degree of enlargement. Frontal tibial angle (mean) was 72°, sagittal tibial angle 63°, frontal femoral angle 47°, sagittal femoral angle 20°, and tunnels divergence angle 36°. Preoperatively, KT-1000 30L and Lachman test scores were 5.52 and 5.79 respectively. In the last follow-up, 30L and manual Lachman test scores were 0.97 and 1.13, respectively ( p  verticalization.

    One of the most important topics on valuation is the appropriate relationships between cash flows and rate of returns. I review those relationships under the premise, by Myers (1974), of the cost of debt as the right discount for the tax shield. Different hypotheses have been advanced for the tax shield risk, each one producing different valuation results, especially when growth is present. The consequences of some common mistakes on valuation are explored. One difference between the results ...

  20. Mining by-products show potential

    , transition metals, metalloids and anions such as arsenate have been effectively removed from wastewater. This process purifies the wastewater from mines in a faster, more effective way that does not require large amounts of infrastructure or difficult chemistry to achieve it. The advantages don't stop there. The hydrotalcites themselves are easily removed using centrifugation, leaving behind a much cleaner sludge and a lot less of it. Initial results have shown the treatment produces around 80 to 90% less sludge than that of lime-based treatments — so it does not present the same scale of handling and final disposal problems. The hydrotalcite-treated water can be recycled back into the plant to lower the total cost of water used in the mining operations, ultimately helping to reduce water consumption as there will be less water drawn from the environment such as from the groundwater near to the mine. This would be particularly valuable for mining operations in arid regions with limited water supply such as in Australia and Chile. Around the world the minerals industry is keen to find more efficient ways to treat their wastewaters and reduce their environmental footprint. With the inherent technical advantages and added benefits of using hydrotalcites, there's a high likelihood of the mining industry adopting this technology on a global scale. The steps to making this a reality have already been made, with commercialisation of the technology underway via Australian company Virtual Curtain. There is also the potential use the treatment to reprocess and recover valuable commodities and produce 'ore- grade' material out of the contaminants. The material can be fed back into the recovery process to recover a greater proportion of the contained metals. This is a very real example of extracting 'wealth from waste', opening up the possibility of partially offsetting wastewater treatment costs for the mining industry.

    Full Text Available "THE SHOW MUST GO ON!" LIABILITY WHEN IT COMES TO DRAMA STUDENTS WHEN INJURED WHILE IN TRAININGThis article emphasises the uncertainty in the relationship between a student undergoing practical training and his/her lecturer or university, if the student should be injured and wants to claim compensation. One must first establish whether the student can be described as an employee of the lecturer or university, or as a vocational worker or independent contractor. Once the status of the student has been established, the relevant legislation can be determined, whether it is the Labour Relations Act or the Basic Conditions of Employment. It is, however, not that simple and a person in the capacity of a student does not accord with the definition of an employee or an independent contractor or a vocational worker. One will have to rely on the assumption in section 83A in the Basic Conditions of Employment that a student is an employee when he does practical training for the benefit of the university. The Occupational Health and Safety Act requires employers to assure that the workplace is a safe environment for employees, with the minimum risks involved. The Compensation for Occupational Injuries and Diseases Act makes it possible for an employee to claim compensation when such a risk becomes a reality.This article also tries to compare the situation of a student sports person injured while participating in university sports, and a drama student injured during a performance or rehearsal of a play. It is stated that the relationship between the drama student and lecturer is similar to the relationship between a sports person and his/her coach, but the relationship differs in that a sports person’s risk of getting hurt is much greater than that of a drama student, The contracts between sports players and their authorities are also stipulated in much more detail than the contracts (if any between the drama students and the university.

    Investigating the impact of Angelman syndrome on the sibling relationship. This study explored differences in sibling relationships between children with a typically-developing sibling (n = 55) and children with a sibling with Angelman syndrome (n = 44). Sibling relationships were compared on four factors and 16 sub-scales of the Sibling Relationship Questionnaire-Revised. Results showed significant differences in mean scores on each of the four factors (i.e. Warmth/Closeness, Conflict, Rivalry and Dominance/Nurturance) and most of the sub-scales. ANCOVAs showed that demographic variables (number of siblings, living in a two-parent vs single parent household, gender, participant's age, place of residence) did not influence significant differences in sibling relationships between the two groups. Having a brother or sister with Angelman syndrome may influence the way in which the sibling perceives the sibling relationship. This may have important implications for family-centred intervention for this population.

    Full Text Available Due to the increasing concern of the organizations with the constant developments and changes in business processes, especially with regard to the quality of its products and services, it became necessary to conduct studies on ways of approaching clients and prospecting for new customers. This practice gained paramount importance to add value to the organization, and increasingly understand the needs of customers through relationship marketing. This study aims to investigate the perception of customers regarding relationship marketing tools used by the company Souza Cruz AS. Therefore, we present the main concepts involving relationship marketing process and customer loyalty. The methodology used was divided into two stages, the first being exploratory and qualitative literature and the second is descriptive and quantitative literature. The sample of 50 clients of Souza Cruz. The results show that customers consider important the relationship with the company, which is proven by the average search attributes in communication / attendance of employees (4.35 in degree of importance, and 4.58 in satisfaction. In the synthesis of overall satisfaction, the mean degree of satisfaction given by the research sample is 3.98. This percentage was considered good, as close to the item content (grade 4. This result may be related to the work of relationship the company Souza Cruz has been performing with his team which seeks to constantly enhance its customers to build strong and lasting relationships.

    Full Text Available This study confirmed a hypothesis from the Emotion-in-Relationships conceptual model, which predicts that greater interdependence between relationship partners—or closeness—creates the potential for jealousy. The study also sought to better define the positive side of romantic jealousy in addition to its more negative attributes. College students in premarital relationships (N = 229 completed a questionnaire, including 27 different measures and the Multidimensional Jealousy Scale. Select data were obtained from 122 cases at 3-month follow-up. Each jealousy scale was tested for associations with demographic (age, sex, and race, person (life satisfaction, loneliness, romantic attachment styles, love styles, and romantic beliefs, and relationship (affective, closeness, and social exchange theory constructs. Results clearly distinguished emotional/reactive jealousy as mostly “good” and cognitive/suspicious jealousy as “bad.” Behavioral jealousy was associated with few measures. Implications are discussed for the interdependence model of relationships and the transactional model of jealousy.

  7. Mitochondrial genome sequencing helps show the evolutionary mechanism of mitochondrial genome formation in Brassica

    2011-01-01

    Background Angiosperm mitochondrial genomes are more complex than those of other organisms. Analyses of the mitochondrial genome sequences of at least 11 angiosperm species have showed several common properties; these cannot easily explain, however, how the diverse mitotypes evolved within each genus or species. We analyzed the evolutionary relationships of Brassica mitotypes by sequencing. Results We sequenced the mitotypes of cam (Brassica rapa), ole (B. oleracea), jun (B. juncea), and car (B. carinata) and analyzed them together with two previously sequenced mitotypes of B. napus (pol and nap). The sizes of whole single circular genomes of cam, jun, ole, and car are 219,747 bp, 219,766 bp, 360,271 bp, and 232,241 bp, respectively. The mitochondrial genome of ole is largest as a resulting of the duplication of a 141.8 kb segment. The jun mitotype is the result of an inherited cam mitotype, and pol is also derived from the cam mitotype with evolutionary modifications. Genes with known functions are conserved in all mitotypes, but clear variation in open reading frames (ORFs) with unknown functions among the six mitotypes was observed. Sequence relationship analysis showed that there has been genome compaction and inheritance in the course of Brassica mitotype evolution. Conclusions We have sequenced four Brassica mitotypes, compared six Brassica mitotypes and suggested a mechanism for mitochondrial genome formation in Brassica, including evolutionary events such as inheritance, duplication, rearrangement, genome compaction, and mutation.

    We examined the extent to which individual relationships with mother and father, social support from partner, and quality of the relationship with the partner, are related to work orientation and work ethic. Survey data were obtained from 3841 respondents from the Netherlands Kinship Panel Study (wave 2). The results showed that, overall, people with a more positive relationship with their parents had a more positive work orientation and a stronger work ethic. A positive relationship with the father had a greater influence on these work aspects than a positive relationship with the mother, particularly for men. Partner support and the quality of the partner relationship partially mediated the association between the relationship with one's parents and work orientation only for women. There were no significant relationships between partner support or the quality of the partner relationship, and work ethic. Research on the relationship with parents and work-related variables is discussed.

    Full Text Available Two field studies were undertaken to investigate the nature of the relationship between justice perceptions and feedback reactions. Previous work suggests that the relationship between procedural justice and feedback reactions is mediated by the quality of the relationship with the supervisor. However, there are also good theoretical reasons to hypothesise that the relationship between justice perceptions and feedback reactions is moderated by relationship quality. Across two field studies, we found support for both mediated and moderated relationships. Results of the moderator analyses showed that the positive relationship between justice perceptions and feedback reactions was more pronounced for subordinates in a low-quality relationship with their supervisor. The present results provide useful suggestions for enhancing feedback reactions in organisations.

    The purpose of this study was to gain a better understanding of stock-type horse show competitors' understanding of welfare and level of concern for stock-type show horses' welfare. Data were collected through an online questionnaire that included questions relating to (a) interest and general understanding of horse welfare, (b) welfare concerns of the horse show industry and specifically the stock-type horse show industry, (c) decision-making influences, and (d) level of empathic characteristics. The majority of respondents indicated they agree or strongly agree that physical metrics should be a factor when assessing horse welfare, while fewer agreed that behavioral and mental metrics should be a factor. Respondent empathy levels were moderate to high and were positively correlated with the belief that mental and behavioral metrics should be a factor in assessing horse welfare. Respondents indicated the inhumane practices that most often occur at stock-type shows include excessive jerking on reins, excessive spurring, and induced excessive unnatural movement. Additionally, respondents indicated association rules, hired trainers, and hired riding instructors are the most influential regarding the decisions they make related to their horses' care and treatment.

    Urothelial carcinomas originate from the epithelial cells of the inner lining of the bladder and may appear as single or as multiple synchronous tumors. Patients with urothelial carcinomas frequently show recurrences after treatment making follow-up necessary. The leading hypothesis explaining the origin of meta- and synchronous tumors assumes a monoclonal origin. However, the genetic relationship among consecutive tumors has been shown to be complex in as much as the genetic evolution does not adhere to the chronological appearance of the metachronous tumors. Consequently, genetically less evolved tumors may appear chronologically later than genetically related but more evolved tumors. Forty-nine meta- or synchronous urothelial tumors from 22 patients were analyzed using expression profiling, conventional CGH, LOH, and mutation analyses. We show by CGH that partial chromosomal losses in the initial tumors may not be present in the recurring tumors, by LOH that different haplotypes may be lost and that detected regions of LOH may be smaller in recurring tumors, and that mutations present in the initial tumor may not be present in the recurring ones. In contrast we show that despite apparent genomic differences, the recurrent and multiple bladder tumors from the same patients display remarkably similar expression profiles. Our findings show that even though the vast majority of the analyzed meta- and synchronous tumors from the same patients are not likely to have originated directly from the preceding tumor they still show remarkably similar expressions profiles. The presented data suggests that an expression profile is established early in tumor development and that this profile is stable and maintained in recurring tumors

    2015-08-01

    Previous studies suggest that owners often wrongly perceive overweight dogs to be in normal condition. The body shape of dogs attending shows might influence owners' perceptions, with online images of overweight show winners having a negative effect. This was an observational in silico study of canine body condition. 14 obese-prone breeds and 14 matched non-obese-probe breeds were first selected, and one operator then used an online search engine to identify 40 images, per breed, of dogs that had appeared at a major national UK show (Crufts). After images were anonymised and coded, a second observer subjectively assessed body condition, in a single sitting, using a previously validated method. Of 1120 photographs initially identified, 960 were suitable for assessing body condition, with all unsuitable images being from longhaired breeds. None of the dogs (0 per cent) were underweight, 708 (74 per cent) were in ideal condition and 252 (26 per cent) were overweight. Pugs, basset hounds and Labrador retrievers were most likely to be overweight, while standard poodles, Rhodesian ridgebacks, Hungarian vizslas and Dobermanns were least likely to be overweight. Given the proportion of show dogs from some breeds that are overweight, breed standards should be redefined to be consistent with a dog in optimal body condition. British Veterinary Association.

    1997-01-01

    In this theoretical analysis, we argue that a process referred to as minding is essential for a couple to feel mutually close and satisfied in a close relationship over a long period Minding represents a package of mutual self-disclosure, other forms of goal-oriented behavior aimed at facilitating the relationship, and attributions about self's and other's motivations, intentions, and Mort in the relationship. Self-disclosure and attribution activities in minding are aimed at getting to know the other, trying to understand the other's motivations and deeper disposition as they pertain to the relationship, and showing respect and acceptance for knowledge gained about other. We link the concept of minding to other major ideas and literatures about how couples achieve closeness: self-disclosure and social penetration, intimacy, empathy and empathic accuracy, and love and self-expansion. We argue that the minding process articulated here has not previously been delineated and that it is a useful composite notion about essential steps in bonding among humans. We also argue that the minding concept stretches our understanding of the interface of attribution and close relationships. We present research possibilities and implications and consider possible alternative positions and counter arguments about the merits of the minding idea for close relationship satisfaction.

    Following a lengthy strike, several hundred delivery drivers filed workers compensation claims for occupational hearing loss. We were asked to evaluate the noise exposure of the drivers during their in-plant tasks. In-plant exposures were not predictive of any hearing loss. A comparison of audiometric data for the claimants revealed consistent hearing loss independent of duration of employment or age. These discrepancies between observations and common understanding of dose-response relationships between noise exposure and hearing loss led to further investigation, ultimately resulting in the dismissal of all claims against the employer who then filed an action against the claimant's attorneys and physician under the Racketeering in Corrupt Organizations Act (RICO). The details of the legal complaint, which reads like a detective novel, can be found at the United States District Court for the Southern District of New York [93 Civ. 7222 (LAP)].

    2015-01-01

    We examined the extent to which three sibling structure variables number of siblings, birth order, and presence of an older sibling at school age are linked to the second language skills of bilingual children. The research questions were tested using an ethnically heterogeneous sample of 1209 bilingual children with German as a second language. Controlling for children’s age, sex, nationality, number of children’s books at home, family language and parental German language skills, hierarchical regression analyses showed an inverse relationship between the number of siblings and second language skills: the more siblings a child had, the lower was his/her second language proficiency. This relationship was mediated by attendance in early education institutions. Moreover, first-born siblings showed better second language skills than later born siblings. The current study revealed that the resource dilution model, i.e., the decrease in resources for every additional sibling, holds for second language acquisition. Moreover, the results indicate that bilingual children from families with several children benefit from access to early education institutions. PMID:26089806

    2016-05-09

    Purpose - The purpose of this paper is to develop evident-based predictive no-show models considering patients' each past appointment status, a time-dependent component, as an independent predictor to improve predictability. Design/methodology/approach - A ten-year retrospective data set was extracted from a pediatric clinic. It consisted of 7,291 distinct patients who had at least two visits along with their appointment characteristics, patient demographics, and insurance information. Logistic regression was adopted to develop no-show models using two-thirds of the data for training and the remaining data for validation. The no-show threshold was then determined based on minimizing the misclassification of show/no-show assignments. There were a total of 26 predictive model developed based on the number of available past appointments. Simulation was employed to test the effective of each model on costs of patient wait time, physician idle time, and overtime. Findings - The results demonstrated the misclassification rate and the area under the curve of the receiver operating characteristic gradually improved as more appointment history was included until around the 20th predictive model. The overbooking method with no-show predictive models suggested incorporating up to the 16th model and outperformed other overbooking methods by as much as 9.4 per cent in the cost per patient while allowing two additional patients in a clinic day. Research limitations/implications - The challenge now is to actually implement the no-show predictive model systematically to further demonstrate its robustness and simplicity in various scheduling systems. Originality/value - This paper provides examples of how to build the no-show predictive models with time-dependent components to improve the overbooking policy. Accurately identifying scheduled patients' show/no-show status allows clinics to proactively schedule patients to reduce the negative impact of patient no-shows.

    In the 1980s the Japanese “keiretsu” system of interconnected business groups was praised as a model to emulate, but since then Japan has often been criticized for being less innovative than the United States. In this paper we connect the two views and argue that tight business relationships can...... suppliers and start cooperation immediately with new suppliers. We first consider broad innovations: every period, one supplier has the opportunity to create a higher quality input that can be used by all producers. Since relationships are harder to break in the cooperative equilibrium the market size...... for potential innovators is smaller and the rate of innovation might be lower than in the noncooperative equilibrium. We contrast this with a setting with relationship-specific innovations that we show are encouraged by the establishment of relational contracts. We illustrate the predictions of the model using...

    A combined history of violence toward self and others has been reported in clinical and incarcerated populations. Psychiatric disorders have been implicated as risk factors. This study examines the lifetime prevalence of this combined violence in the general population and its associations with DSM-5 psychiatric disorders in comparison with other- and self-directed violence. Data from the National Epidemiologic Survey on Alcohol and Related Conditions-III (NESARC-III) were analyzed, including 36,309 U.S. adults ages 18 and older. Violent behavior was defined by suicide attempts; recurrent suicidal behavior; gestures, threats, or self-mutilating behavior (self-directed); and multiple items of violence toward others (other-directed) in four categories: none, self-directed only, other-directed only, and combined self-/other-directed. Multinomial logistic regression examined these violence categories in association with sociodemographics and lifetime DSM-5 psychiatric disorders. Results show that approximately 18.1% of adults reported violent behavior, including self-directed only (4.4%), other-directed only (10.9%), and combined self- and other-directed violence (2.8%). DSM-5 psychiatric disorders significantly associated with the violence typology include alcohol, tobacco, cannabis, and other drug use disorders; mood disorders; posttraumatic stress disorder; and schizotypal, antisocial, and borderline personality disorders. Findings extend the clinical literature regarding the co-occurrence of self- and other-directed violent behaviors to the general population. Copyright © 2017 Elsevier B.V. All rights reserved.

    Social relationships are fundamental to animals living in complex societies. The extent to which individuals base their decisions around their key social relationships, and the consequences this has on their behavior and broader population level processes, remains unknown. Using a novel experiment that controlled where individual wild birds (great tits, Parus major) could access food, we restricted mated pairs from being allowed to forage at the same locations. This introduced a conflict for pair members between maintaining social relationships and accessing resources. We show that individuals reduce their own access to food in order to sustain their relationships and that individual foraging activity was strongly influenced by their key social counterparts. By affecting where individuals go, social relationships determined which conspecifics they encountered and consequently shaped their other social associations. Hence, while resource distribution can determine individuals' spatial and social environment, we illustrate how key social relationships themselves can govern broader social structure. Finally, social relationships also influenced the development of social foraging strategies. In response to forgoing access to resources, maintaining pair bonds led individuals to develop a flexible "scrounging" strategy, particularly by scrounging from their pair mate. This suggests that behavioral plasticity can develop to ameliorate conflicts between social relationships and other demands. Together, these results illustrate the importance of considering social relationships for explaining behavioral variation due to their significant impact on individual behavior and demonstrate the consequences of key relationships for wider processes.

    The student-educator relationship in nursing is very important to the success of teaching and learning. The perceptions of students and educators of this relationship affect its success. Therefore, it is necessary to better understand this relationship. The purpose of the current study was to explore Iranian nursing students' and educators' perceptions of student-educator relationship in clinical nursing education. In this conventional content analysis study, eight Bachelor of Nursing students and 10 clinical nursing educators from nursing and midwifery school in Mashhad (Iran) participated. Purposive sampling was used to select participants. Data were gathered using semistructured interviews. To analyze data, a conventional content analysis approach was used to identify meaning units and their condensation and to make codes and create categories : Results showed that the multidimensional nature of the student-educator relationship in clinical nursing education consists of (a) dimensions related to the educator, (b) dimensions related to the student, and (c) dimensions of relationship quality. Each of these categories is composed of codes that showed the perception of participants about the nature of relationship. On the basis of the unique features and attributes regarding relationship perceptions in clinical nursing education identified among the participants of this study, students and educators in Iran should pay greater attention to establishing the relationship as it relates to these attributes.

    Full Text Available A large number of banks let people be more free in choosing the best bank for their needs. People can freely switch from one bank to another which makes the loyalty level of bank customers decrease, even though the efforts and cost spent for maintaining the customers is cheaper than the efforts and cost spent on getting new customers. Relationship is one of the answers to the problem, relationship marketing is a marketing principle which emphasizes and takes effort in maintaining good long term relationship with customers. This research aims to, analyze the influence competence, communication, and conflict handling towards relationship quality, mediated by relationship quality, and towards customer loyalty. The research was conducted by collecting quantitative data through questionnaires distributed to 130 respondents. The objects of this research were the priority customers at Niaga Bank, and it used purposive sampling technique. This research conducted by using Structural Equation Model method. The result of this research showed that, (1 relationship marketing which consists of competence component, communication, and conflict handling have significant influence and positively towards relationship quality, partially and simultaneously, (2 relationship marketing have significant influence and positively towards customer loyalty which is mediated by relationship quality, and (3 relationship quality have significant influence and positively towards customer loyalty.

    Research suggests that self-esteem increases during late adolescence and young adulthood, but that there is large interindividual variability in this development. However, little is known about the factors accounting for these findings. Using propensity score matching, we tested whether important transitions in the domain of romantic relationships (i.e., beginning a relationship, marrying, and breaking up) explain why individuals differ in the particular self-esteem trajectory they follow. Data came from a longitudinal German study with a large sample of 3 nationally representative cohorts of late adolescents and young adults (total N = 9,069). The analyses were based on 4 assessments across a 3-year period. Using matched samples, the results showed that beginning a relationship increased self-esteem and that the increase persisted when the relationship held at least for 1 year. Experiencing a relationship break-up decreased self-esteem, but the effect disappeared after 1 year, even if the participant stayed single. Marrying did not influence self-esteem. Additionally, we tested for selection effects of self-esteem on the later occurrence of relationship transitions. High self-esteem predicted the beginning of a relationship and low self-esteem predicted relationship break-up. All findings held across gender, age, and migration background. Furthermore, relationship quality mediated the effect of self-esteem on relationship break-up and the effect of beginning a longer versus a short relationship on self-esteem. The findings have significant implications because they show that self-esteem influences whether important transitions occur in the relationship domain and that, in turn, experiencing these transitions influences the further development of self-esteem.

    2015-08-01

    Full Text Available Through forgiveness, people reduce negative responses toward their transgressors, and are more motivated to show positive behaviors instead. Two studies were performed with the aim to approach the phenomenon of forgiveness. The first study, in which 101 university students participated, aimed to examine the differenttypes of transgressions depending on the type of relationship (friendship vs. couple and gender. In thesecond study (n = 201 participants from general population, we studied the influence of gender, emotional, and motivational variables on forgiveness after infidelity betrayal. Results of the first study showed that infidelity is perceived as the most serious transgression. In the second study, results showed that inunfaithful transgression, women perceived the consequences as more serious, felt more negative emotionsand showed greater empathy and dependency than men. Also, empathy in men as well as dependency in women were found to predict revenge, and resulted in less forgiveness. Finally, results showed that in both men and women, the negative affect mediated the relationship between severity of transgression andmotivation to retaliate as a result of infidelity.

    Full Text Available We investigated variation in baseline cortisol levels in relation to relationship status (single or in a relationship, relationship characteristics (length, stability, presence or absence of clear dominance, or individual attributes (dominant or subordinate status, relative physical attractiveness, relationship worries. Study participants were 77 men and 75 women aged between 18 and 38 years. Individuals in romantic relationships had lower cortisol levels than singles. Individuals of African ethnicity, however, showed the opposite pattern. Individuals who perceived their relationship to be highly unstable had higher cortisol levels. Aside from African-Americans, married individuals reported the lowest relationship instability and the lowest cortisol levels, followed by individuals in long-term relationships, and by individuals in short-term relationships. The presence or absence of clear dominance in the relationship, dominance status, or relationship worries did not affect cortisol levels. Therefore relationship status and relationship instability were better predictors of variation in cortisol (presumably through stress-related mechanisms than individual attributes.

This paper discusses only the pressure locking phenomenon in a flexible-wedge gate valve; the authors will publish the results of their thermal binding research at a later date. Pressure locking can occur when operating sequences or temperature changes cause the pressure of the fluid in the bonnet (and, in most valves, between the discs) to be higher than the pressure on the upstream and downstream sides of the disc assembly. This high fluid pressure presses the discs against both seats, making the disc assembly harder to unseat than anticipated by the typical design calculations, which generally consider friction at only one of the two disc/seat interfaces. The high pressure of the bonnet fluid also changes the pressure distribution around the disc in a way that can further contribute to the unseating load. If the combined loads associated with pressure locking are very high, the actuator might not have the capacity to open the valve. The results of the NRC/INEL research discussed in this paper show that the relationship between bonnet pressure and pressure locking stem loads appears linear. The results also show that for this valve, seat leakage affects the bonnet pressurization rate when the valve is subjected to thermally induced pressure locking conditions.

    In this study we tested the hypothesis that participants higher in dispositional self-compassion would show lower stress-induced reactivity of salivary alpha-amylase (sAA), a marker of sympathetic nervous system activation. Thirty-three healthy participants (18-34 years old) were exposed to a standardized laboratory stressor on two consecutive days. Self-compassion, self-esteem, and demographic factors were assessed by questionnaire and sAA was assessed at baseline and at 1, 10, 30, and 60 minutes following each stressor. Self-compassion was a significant negative predictor of sAA responses on both days. This relationship remained significant when controlling for self-esteem, subjective distress, age, gender, ethnicity, and Body Mass Index (BMI). These results suggest that self-compassion may serve as a protective factor against stress-induced physiological changes that have implications for health.

    To investigate the relationship between function and disease activity in early inflammatory arthritis (EIA). Canadian Early Arthritis Cohort (CATCH) (n=1143) is a multi-site EIA cohort. Correlations between the Health Assessment Questionnaire Disability Index (HAQ) and DAS28 were done at every 3 months for the first year and then at 18 and 24 months. We also investigated the relationship between HAQ and DAS28 by age (<65 versus ≥65) and RF (positive vs negative). Mean HAQ and DAS28 scores were highest at the initial visit with HAQ decreasing over 24 months from a baseline of 0.94 to 0.40 and DAS28 scores decreasing from 4.54 to 2.29. All correlations between HAQ and DAS28 were significant at all time points (p<0.01). The correlations between HAQ and DAS28 were variable over time. The strongest correlation between HAQ and DAS28 occurred at initial visit (most DMARD naive) (n=1,143) and 18 months (r=0.57, n=321) and 24 months (r=0.59, n=214). The baseline correlation between HAQ and DAS28 was significantly different than correlations obtained at 3, 6, and 12 months (p=0.02, 0.01, and 0.01, respectively). Age did not change the association between HAQ and DAS28 {<65 years old (r=0.50, n=868) versus ≥65 (r=0.48, n=254), p=0.49}. The correlation between HAQ and DAS28 was stronger with RF+ patients (r=0.63, n=636) vs RF negative (r=0.47, n=477), p=0.0043. Over 2 years in EIA, HAQ and DAS both improved; correlations at time points were different over 2 years and RF status affected the correlations.

  5. Airline Overbooking Problem with Uncertain No-Shows

    Full Text Available This paper considers an airline overbooking problem of a new single-leg flight with discount fare. Due to the absence of historical data of no-shows for a new flight, and various uncertain human behaviors or unexpected events which causes that a few passengers cannot board their aircraft on time, we fail to obtain the probability distribution of no-shows. In this case, the airlines have to invite some domain experts to provide belief degree of no-shows to estimate its distribution. However, human beings often overestimate unlikely events, which makes the variance of belief degree much greater than that of the frequency. If we still regard the belief degree as a subjective probability, the derived results will exceed our expectations. In order to deal with this uncertainty, the number of no-shows of new flight is assumed to be an uncertain variable in this paper. Given the chance constraint of social reputation, an overbooking model with discount fares is developed to maximize the profit rate based on uncertain programming theory. Finally, the analytic expression of the optimal booking limit is obtained through a numerical example, and the results of sensitivity analysis indicate that the optimal booking limit is affected by flight capacity, discount, confidence level, and parameters of the uncertainty distribution significantly.

    To clarify the relationship between human quality and reliability, 1925 experiments in 20 subjects were carried out to study the relationship between disposition character, digital memory, graphic memory, multi-reaction time and education level and simulated aircraft operation. Meanwhile, effects of task difficulty and enviromental factor on human reliability were also studied. The results showed that human quality can be predicted and evaluated through experimental methods. The better the human quality, the higher the human reliability.

  7. Human Factor in Therapeutic Relationship

    Full Text Available herapeutic relationship is a professional relationship that has been structured based on theoretical props. This relationship is a complicated, wide and unique relationship which develops between two people, where both sides' personality and attitudes inevitably interfere. Therapist-client relationship experienced through transference and counter transference, especially in psychodynamic approaches, is accepted as the main aspect of therapeutic process. However, the approaches without dynamic/deterministic tendency also take therapist-client relationship into account seriously and stress uniqueness of interaction between two people. Being a person and a human naturally sometimes may negatively influence the relationship between the therapist and client and result in a relationship going out of the theoretical frame at times. As effective components of a therapeutic process, the factors that stem from being human include the unique personalities of the therapist and the client, their values and their attitude either made consciously or subconsciously. Literature has shown that the human-related factors are too effective to be denied in therapeutic relationship process. Ethical and theoretical knowledge can be inefficient to prevent the negative effects of these factors in therapeutic process at which point a deep insight and supervision would have a critical role in continuing an acceptable therapeutic relationship. This review is focused on the reflection of some therapeutic factors resulting from being human and development of counter transference onto the therapeutic process.

    Dolphin shows and dolphin interaction programs are two types of education programs within zoological institutions used to educate visitors about dolphins and the marine environment. The current study examined the short- and long-term effects of these programs on visitors' conservation-related knowledge, attitude, and behavior. Participants of both dolphin shows and interaction programs demonstrated a significant short-term increase in knowledge, attitudes, and behavioral intentions. Three months following the experience, participants of both dolphin shows and interaction programs retained the knowledge learned during their experience and reported engaging in more conservation-related behaviors. Additionally, the number of dolphin shows attended in the past was a significant predictor of recent conservation-related behavior suggesting that repetition of these types of experiences may be important in inspiring people to conservation action. These results suggest that both dolphin shows and dolphin interaction programs can be an important part of a conservation education program for visitors of zoological facilities. © 2012 Wiley Periodicals, Inc.

Use of Matlab software on the experimental results showing that project earning volatility influences investment probability, led the authors to conclude that this notion is not always correct, as increasing uncertainty should have an inhibiting effect on investment, and that in certain situation, increasing uncertainty actually increases the investment probability and so, should have positive impact on investment.

    Full Text Available The main objective of the study was to obtain information about social network variables in order to predict the relational commitment of married individuals and people having dating relationships. For this purpose, social network analysis has been carried out on 134 people having dating relationship and 154 married individuals and then Relationship Stability Scale, Subjective Norm Scale and Social Network Feature Survey prepared by the researcher were used. The results indicated that the approval of the closest social network member and the level of enjoyment of each other’s social network members had the best predictive value for relationship satisfaction and the investment to the relationship. The results also demonstrated that, approval of the social network had a negative impact on the level of the quality of alternatives and it showed that social networks were seen as a barrier function to have alternative relationships. Furthermore, by dividing social network members into two groups, for the dating group, the approval of the social network was the most significant variable for commitment but in the married group, the need for social network approval was not an important criteria because of having their relatioship already confirmed legally. When social network members were categorised and examined, the closest social network members did not differ by sex, but were varied in terms of relationship types. In the flirt group, one of their friends among his/her social network and their partners’ social network was specified as the closest social network member whereas in the married group, the closest social network member among his/her social network was their mother while it was their sibling among partner’s social network.

    2016-01-01

    Previous research has demonstrated that anxiety reliably predicts later depression, but little has been uncovered about the mechanism underlying this connection. Interpersonal relationships appear to be a viable mechanism of the association as anxiety has been shown to predict later deficits in both close (e.g., "best friendships") and group relationships (e.g., classroom peer groups), and deficits in both close and group relationships have been linked to later depressive symptoms. The current study examined close and group relationships as potential mediators between anxiety and depression 12-14 years later. In a nationally representative sample of adolescents (N = 6,504), anxiety was measured at baseline, perceptions of close relationships (i.e., feeling loved) and perceptions of group relationships (i.e., feeling part of a group) were measured 6 months later, and depression levels and diagnosis were measured 12-14 years later. Using structural equation models, the results showed that adolescent perceptions of both close and group relationships significantly mediated the relationship between adolescent anxiety and adult levels of depression. Furthermore, perceptions of not being accepted/loved in close relationships significantly mediated the relationship between adolescent anxiety and clinical depression in adulthood. These results suggest that a perception of not being accepted in group relationships may be a mechanism by which heightened anxiety in adolescents leads to heightened nonclinical depression in adulthood. On the other hand, adolescent perceptions of not feeling loved or accepted in close relationships may be a mechanism by which heightened anxiety in adolescence leads to clinical depression--in adulthood. © 2015 Wiley Periodicals, Inc.

    Full Text Available Romantic relationship among adolescents are common everywhere however not all of us are true natural born, hopeful romantics. Yet there are those who struggle with the whole concept. It is not because they don’t want to enjoy it with their partner but has more to do with their never having understood it. No relationships-themed resource would be complete without some helpful insights regarding the subject of romance. This study was conducted to discover whether or not there is an association between the profile and involvement in a romantic relationship among adolescent. It also outlined the timing of romantic attachment formation and its implications for relationship stability. Fifty high school students attending Batangas National High School were surveyed. Approximately one hundred percent of those surveyed were involved in a relationship. Results showed that adolescents are generally satisfied with their romantic relationships. The respondents are already confident in establishing romantic relationship. The relationship between the length of the romantic relationship and the level of satisfaction was found to be positive

    Late ventricular potentials (LPs) are considered to be useful for identifying patients with heart failure at risk of developing ventricular arrhythmias. 123 I-metaiodobenzylguanidine (MIBG) scintigraphy, which is used to evaluate cardiac sympathetic activity, has demonstrated cardiac sympathetic denervation in patients with malignant ventricular tachyarrhythmias. This study was undertaken to clarify the relationship between LPs and 123 I-MIBG scintigraphy findings in patients with dilated cardiomyopathy (DCM). A total of 56 patients with DCM were divided into an LP-positive group (n = 24) and an LP-negative group (n = 32). During the compensated period, the delayed heart/mediastinum count (H/M) ratio, delayed total defect score (TDS), and washout rate (WR) were determined from 123 I-MIBG images and plasma brain natriuretic peptide (BNP) concentrations were measured. Left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), and left ventricular ejection fraction (LVEF) were simultaneously determined by echocardiography. LVEDV, LVESV, LVEF and plasma BNP concentrations were similar in the two groups. However, TDS was significantly higher (35 ± 8 vs. 28 ± 6, p 123 I-MIBG scintigraphic parameters were worse in LP-positive DCM patients than in LP-negative DCM patients. Furthermore, in LP-positive DCM patients with a high WR, the incidence of sudden death events was higher than that in other subgroups of DCM patients. (orig.)

    In this paper, we present a new method to predict the Taiwan Stock Exchange Capitalization Weighted Stock Index (TAIEX) based on fuzzy-trend logical relationship groups (FTLRGs). The proposed method divides fuzzy logical relationships into FTLRGs based on the trend of adjacent fuzzy sets appearing in the antecedents of fuzzy logical relationships. First, we apply an automatic clustering algorithm to cluster the historical data into intervals of different lengths. Then, we define fuzzy sets based on these intervals of different lengths. Then, the historical data are fuzzified into fuzzy sets to derive fuzzy logical relationships. Then, we divide the fuzzy logical relationships into FTLRGs for forecasting the TAIEX. Moreover, we also apply the proposed method to forecast the enrollments and the inventory demand, respectively. The experimental results show that the proposed method gets higher average forecasting accuracy rates than the existing methods.

    This article reports an explorative study which aims to investigate hospitalized children's views of their relationships with nurses and doctors. Twenty-seven school-aged children and adolescents from 6 to 15 years old in the paediatric haematology and oncology ward of an Italian hospital participated in the study. Each participant was asked to draw him or herself with a doctor or nurse from the ward while they were doing something. The drawings were analysed using Pictorial Assessment of Interpersonal Relationships (PAIR) and a qualitative analysis. The results showed that the participants viewed their relationships with health professionals positively, in particular with the nurses. This relationship was perceived as close, intimate, cohesive and without conflict. In some cases it became an emotional bond. Finally, this relationship helped the patients to cope with painful and uncomfortable medical procedures, which gradually became familiar and accepted. The clinical implications of this study are discussed.

    We say that a population is perfectly polarized when divided in two groups of the same size and opposite opinions. In this paper, we propose a methodology to study and measure the emergence of polarization from social interactions. We begin by proposing a model to estimate opinions in which a minority of influential individuals propagate their opinions through a social network. The result of the model is an opinion probability density function. Next, we propose an index to quantify the extent to which the resulting distribution is polarized. Finally, we apply the proposed methodology to a Twitter conversation about the late Venezuelan president, Hugo Chávez, finding a good agreement between our results and offline data. Hence, we show that our methodology can detect different degrees of polarization, depending on the structure of the network.

    In social animals, the fast detection of group members' emotional expressions promotes swift and adequate responses, which is crucial for the maintenance of social bonds and ultimately for group survival. The dot-probe task is a well-established paradigm in psychology, measuring emotional attention through reaction times. Humans tend to be biased toward emotional images, especially when the emotion is of a threatening nature. Bonobos have rich, social emotional lives and are known for their soft and friendly character. In the present study, we investigated (i) whether bonobos, similar to humans, have an attentional bias toward emotional scenes compared with conspecifics showing a neutral expression, and (ii) which emotional behaviors attract their attention the most. As predicted, results consistently showed that bonobos' attention was biased toward the location of the emotional versus neutral scene. Interestingly, their attention was grabbed most by images showing conspecifics such as sexual behavior, yawning, or grooming, and not as much-as is often observed in humans-by signs of distress or aggression. The results suggest that protective and affiliative behaviors are pivotal in bonobo society and therefore attract immediate attention in this species.

    2007-03-01

    To examine the phenomenon of fat stigmatization messages presented in television shows and movies, a content analysis was used to quantify and categorize fat-specific commentary and humor. Fat stigmatization vignettes were identified using a targeted sampling procedure, and 135 scenes were excised from movies and television shows. The material was coded by trained raters. Reliability indices were uniformly high for the seven categories (percentage agreement ranged from 0.90 to 0.98; kappas ranged from 0.66 to 0.94). Results indicated that fat stigmatization commentary and fat humor were often verbal, directed toward another person, and often presented directly in the presence of the overweight target. Results also indicated that male characters were three times more likely to engage in fat stigmatization commentary or fat humor than female characters. To our knowledge, these findings provide the first information regarding the specific gender, age, and types of fat stigmatization that occur frequently in movies and television shows. The stimuli should prove useful in future research examining the role of individual difference factors (e.g., BMI) in the reaction to viewing such vignettes.

    2015-01-01

    Background The quality of social relationships and social support appears to be associated with physical health outcomes and sleep quality. Almost all previous research in this area focuses on positive aspects of relationships. Purpose The present study thus intended to examine the links between supportive, aversive, ambivalent, and indifferent network ties and sleep quality. Methods Relationship data, PSQI-assessed sleep quality, and depression were examined in 175 middle-aged and older adults. Results Consistent with hypotheses, supportive ties were positively related to sleep quality, while aversive ties predicted worse sleep quality; associations that were primarily seen for close relationships. Ambivalent and indifferent ties were not significant predictors of sleep quality. Importantly, depression was found to mediate the link between relationship quality and sleep quality. Conclusions These data suggest the more specific types of social relationships that may be linked to poor sleep quality, and that depression appears to underlie these associations. PMID:25976874

    This study among 267 Greek teachers and their partners tested and expanded the recently proposed Spillover-Crossover model (SCM) of well-being. Accordingly, experiences built up at work spill over to the home domain, and then influence the partner. The authors integrated equity theory in the model by formulating hypotheses about exchange in interpersonal relationships. Structural equation modeling analyses supported the spillover hypothesis that teachers who lose their work engagement as a result of an inequitable relationship with their students invest less in the relationship with their partner. In addition, the results supported the crossover hypothesis that teachers' relationship investments, in turn, show a negative relationship with inequity in the intimate relationship as perceived by the partner; and inequity in the intimate relationship contributed to partner depression. The findings are discussed in light of the SCM of well-being.

    Full Text Available This research administrated to evaluate the psychometric properties of the Persian version of Relationship Assessment scale. Therefore, 315 married individuals (199 women and 116 men from Tehran city were volunteered to respond to four scales: the Relationship Assessment, the Kansas Marital Satisfaction, the Oxford Happiness and the Life Satisfaction. Results from exploratory & confirmatory factor analysis showed that factor structure of Relationship Assessment scale was unidimensional. The internal consistency of the scale in the total sample was 0.88. Significant correlations between scores of the Relationship Assessment scale with the scores of the Kansas Marital Satisfaction Scale, the Life Satisfaction Scale and the Oxford Happiness Questionnaire demonstrated good convergent validity of the scale. Also, the results showed that there was no significant gender difference between the mean scores of relationship satisfaction. In conclusion, the Relationship Assessment scale is a valid and reliable tool to measure marital satisfaction in Iran.

    Full Text Available Abstract Background Kisumu has shown a rising HIV prevalence over the past sentinel surveillance surveys, and most new infections are occurring among youth. We conducted a qualitative study to explore risk situations that can explain the high HIV prevalence among youth in Kisumu town, Kenya Methods We conducted in-depth interviews with 150 adolescents aged 15 to 20, held 4 focus group discussions, and made 48 observations at places where youth spend their free time. Results Porn video shows and local brew dens were identified as popular events where unprotected multipartner, concurrent, coerced and transactional sex occurs between adolescents. Video halls - rooms with a TV and VCR - often show pornography at night for a very small fee, and minors are allowed. Forced sex, gang rape and multiple concurrent relationships characterised the sexual encounters of youth, frequently facilitated by the abuse of alcohol, which is available for minors at low cost in local brew dens. For many sexually active girls, their vulnerability to STI/HIV infection is enhanced due to financial inequality, gender-related power difference and cultural norms. The desire for love and sexual pleasure also contributed to their multiple concurrent partnerships. A substantial number of girls and young women engaged in transactional sex, often with much older working partners. These partners had a stronger socio-economic position than young women, enabling them to use money/gifts as leverage for sex. Condom use was irregular during all types of sexual encounters. Conclusions In Kisumu, local brew dens and porn video halls facilitate risky sexual encounters between youth. These places should be regulated and monitored by the government. Our study strongly points to female vulnerabilities and the role of men in perpetuating the local epidemic. Young men should be targeted in prevention activities, to change their attitudes related to power and control in relationships. Girls

    2013-12-01

    Full Text Available The aim of this paper is to analyze: 1 couple relationships – support functions and characteristics of the relationships – and their difference by gender, and 2 changes that occur in those relationships and in sexual activity in older heterosexual adults in the 65-85 age range. The subjects of the analysis were intentionally selected and the data has been collected in structured and semi-structured interviews. The results obtained by quantitative and qualitative analysis show that the couple relationship in old age fulfills functions such as emotional support, companionship and cognitive advice. Analysis by gender shows significant differences in 4 out of the 5 support functions that were explored. Among the changes that take place in old age, the decrease of frequency in sexual activity appears in the first place, though the level of satisfaction is maintained; and fellowship, mutual care and positive affect in relation to the partner increase.

    Full Text Available This study examines the relationship between organizational climate and women employees' creativity of Tabriz Red Crescent Organization. The research method is descriptive correlation performed among 120 women employed at the Red Crescent and 100 cases were selected for the proposed study. For data collection, Hoy and Miskel (2005's organizational climate and Randsyp creativity questionnaires with 0.78 and 0.82 Cronbach's alpha coefficients were used. Pearson correlation and multiple regressions were used to analyze research hypotheses. Results showed that there was a significant relationship between two indices of manager and subordinate behaviors and creativity. In addition, in investigating the relationship between climate and creativity components, findings showed that there was a significant relationship only between cooperation and pretending to job dimensions and creativity. This study also has shown that managers' behavior is closed and employees' behavior is more open than managers are.

    29 patients showing moderate to markedly pronounced tardive dyskinesia (TD) and a further 29 control patients (C) under a similar long-term medication with neuroleptics that had been so chosen as to match the age and sex distributions of the former group were subjected to computered tomography, neurological examination and psychological testing. The results did not point to any correlations between the structural changes and duration of treatment and the clinical signs or symptoms of extrapyramidal disorder. This was taken as further evidence in support of the theory that the initial damage in tardive dyskinesia mainly is at the level of the basal ganglia. (orig./MG) [de

    2014-11-01

    The concept of "coping styles", or consistently different responses to stressors, is of broad interest in behavioral ecology and biomedicine. Two critical predictions of this concept are individual consistency of neurophysiological and behavioral responses (relative to population variability) and a negative relationship between aggression/proactivity and hypothalamic-pituitary-adrenal axis reactivity. Recent studies failed to provide strong support for these predictions, especially outside of strictly controlled conditions, and long-term measures to test the first prediction are rare. Here, we demonstrate individual repeatability across 2-3years of maximum circulating corticosterone concentration [CORT] and area under the [CORT] response curve (AUCI) during a standard capture-restraint test in wild, free-living adult Nazca boobies (Sula granti). We also show that the stress response predicts the personality traits aggression and anxiety in these birds (measured in the wild); however, the strength of these results was weak. Maximum [CORT] and AUCI showed higher repeatability between years than baseline [CORT]. After controlling breeding status, sex, mass, date sampled, and their interactions, baseline [CORT] was most closely related to personality traits, followed by AUCI, and then maximum [CORT]. The direction of these relationships depended on whether the testing context was social or non-social. [CORT] parameters had little to no relationship with cross-context plasticity in personality traits. Our results generally affirm two critical predictions of coping styles, but match the emerging trend that these relationships are weak in the wild, and may depend on testing context.

    Late ventricular potentials (LPs) are considered to be useful for identifying patients with heart failure at risk of developing ventricular arrhythmias. {sup 123}I-metaiodobenzylguanidine (MIBG) scintigraphy, which is used to evaluate cardiac sympathetic activity, has demonstrated cardiac sympathetic denervation in patients with malignant ventricular tachyarrhythmias. This study was undertaken to clarify the relationship between LPs and {sup 123}I-MIBG scintigraphy findings in patients with dilated cardiomyopathy (DCM). A total of 56 patients with DCM were divided into an LP-positive group (n = 24) and an LP-negative group (n = 32). During the compensated period, the delayed heart/mediastinum count (H/M) ratio, delayed total defect score (TDS), and washout rate (WR) were determined from {sup 123}I-MIBG images and plasma brain natriuretic peptide (BNP) concentrations were measured. Left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), and left ventricular ejection fraction (LVEF) were simultaneously determined by echocardiography. LVEDV, LVESV, LVEF and plasma BNP concentrations were similar in the two groups. However, TDS was significantly higher (35 {+-} 8 vs. 28 {+-} 6, p < 0.005), the H/M ratio was significantly lower (1.57 {+-} 0.23 vs. 1.78 {+-} 0.20, p < 0.005), and the WR was significantly higher (60 {+-} 14% vs. 46 {+-} 12%, p < 0.001) in the LP-positive than in the LP-negative group. The average follow-up time was 4.5 years, and there were nine sudden deaths among the 56 patients (16.1%). In logistic regression analysis, the incidences of sudden death events were similar in those LP-negative with WR <50%, LP-negative with WR {>=}50% and LP-positive with WR <50% (0%, 10.0% and 14.3%, respectively), but was significantly higher (41.2%) in those LP-positive with WR {>=}50% (p < 0.01, p < 0.05, and p < 0.05, respectively). The present study demonstrated that the values of cardiac {sup 123}I-MIBG scintigraphic parameters

    2015-11-01

    This paper investigates the emergence of relationship-based cooperation by coupling two simple mechanisms into the model: tie strength based investment preference and homophily assumption. We construct the model by categorizing game participants into four types: prosocialists (players who prefers to invest in their intimate friends), antisocialists (players who prefer to invest in strangers), egoists (players who never cooperate) and altruists (players who cooperate indifferently with anyone). We show that the relationship-based cooperation (prosocialists) is favored throughout the evolution if we assume players of the same type have stronger ties than different ones. Moreover, we discover that strengthening the internal bonds within the strategic clusters further promotes the competitiveness of prosocialists and therefore facilitates the emergence of relationship-based cooperation in our proposed scenarios. The robustness of the model is also tested under different strategy updating rules and network structures. The results show that this argument is robust against the variations of initial conditions and therefore can be considered as a fundamental theoretical framework to study relationship-based cooperation in reality.

    A promoter polymorphism of the osteopontin (OPN) gene (rs28357094) has been associated with multiple inflammatory states, severity of Duchenne muscular dystrophy (DMD) and muscle size in healthy young adults. We sought to define the mechanism of action of the polymorphism, using allele-specific in vitro reporter assays in muscle cells, and a genotype-stratified intervention in healthy controls. In vitro reporter constructs showed the G allele to respond to estrogen treatment, whereas the T allele showed no transcriptional response. Young adult volunteers (n = 187) were enrolled into a baseline study, and subjects with specific rs28357094 genotypes enrolled into an eccentric muscle challenge intervention [n = 3 TT; n = 3 GG/GT (dominant inheritance model)]. Female volunteers carrying the G allele showed significantly greater inflammation and increased muscle volume change as determined by magnetic resonance imaging T1- and T2-weighted images after eccentric challenge, as well as greater decrement in biceps muscle force. Our data suggest a model where the G allele enables enhanced activities of upstream enhancer elements due to loss of Sp1 binding at the polymorphic site. This results in significantly greater expression of the pro-inflammatory OPN cytokine during tissue remodeling in response to challenge in G allele carriers, promoting muscle hypertrophy in normal females, but increased damage in DMD patients. © The Author 2014.

  15. Radon in Austrian tourist mines and show caves

    2009-01-01

    The radon situation in tourist mines and show caves is barely investigated in Austria. This paper investigates the influence of its determining factors, such as climate, structure and geology. For this purpose, long-term time-resolved measurements over 6 to 12 months in 4 tourist mines and 2 show caves - with 5 to 9 measuring points each - have been carried out to obtain the course of radon concentration throughout the year. In addition, temperature and air-pressure were measured and compared to the data outside where available. Results suggest that the dominating factors of the average radon concentration are structure and location (geology) of the tunnel-system, whereas the diurnal and annual variation is mainly caused by the changing airflow, which is driven by the difference in temperature inside and outside. Downcast air is connected with very low radon concentrations, upcast air with high concentrations. In some locations the maximum values appear when the airflow ceases. But airflow can be different in different parts of mines and caves. Systems close to the surface show generally lower radon levels than the ones located deeper underground. Due to variation of structure, geology and local climate, the radon situation in mines and caves can only be described by simultaneous measurements at several measuring points. (orig.)

    Pseudo-materials are effective in boosting the specific capacitance of supercapacitors, but during service their degradation may also be very strong, causing reduced cycling stability. Here, we show that a carbon nanotube sponge grafted by two conventional pseudo-polymer layers in sequence can serve as a porous supercapacitor electrode with significantly enhanced cycling stability compared with single polymer grafting. Creating conformal polymer coatings on the nanotube surface and the resulting double-sheath configuration are important structural factors leading to the enhanced performance. Combining different polymers as double sheaths as reported here might be a potential route to circumvent the dilemma of pseudo-materials, and to simultaneously improve the capacitance and stability for various energy storage devices.Pseudo-materials are effective in boosting the specific capacitance of supercapacitors, but during service their degradation may also be very strong, causing reduced cycling stability.

    Full Text Available The function and the role phytoceramide (PCER and phytosphingosine (PSO in the central nervous system has not been well studied. This study was aimed at investigating the possible roles of PCER and PSO in glutamate-induced neurotoxicity in cultured neuronal cells and memory function in mice. Phytoceramide showed neuro-protective activity in the glutamate-induced toxicity in cultured cortical neuronal cells. Neither phytosphingosine nor tetraacetylphytosphingosine (TAPS showed neuroproective effects in neuronal cells. PCER (50 mg/kg, p.o. recovered the scopolamine-induced reduction in step-through latency in the passive avoidance test; however, PSO did not modulate memory function on this task. The ameliorating effects of PCER on spatial memory were confirmed by the Morris water maze test. In conclusion, through behavioral and neurochemical experimental results, it was demonstrated that central administration of PCER produces amelioration of memory impairment. These results suggest that PCER plays an important role in neuroprotection and memory enhancement and PCER could be a potential new therapeutic agent for the treatment of neurodegenerative diseases such as Alzheimer’s disease.

  2. Impact velocity vs. target hardness relationships for equivalent response of cask structures

    In this paper, impact velocity vs. target hardness relationships for cask structures are reviewed. The relationships are based on equivalent cask responses in terms of equal deceleration or similar cask damages. By examining several past cask or container tests as well as some analytical results, some conclusions can be drawn about the relationship between target hardness and equivalent impact velocities. This relationship clearly shows that the cask response to impact is cask-dependent and that the rigid sphere impact model results in an unconservative estimate of equivalent velocity

    2005-01-01

    Automatic and controlled modes of evaluation sometimes provide conflicting reports of the quality of social objects. This paper presents evidence for four moderators of the relationship between automatic (implicit) and controlled (explicit) evaluations. Implicit and explicit preferences were measured for a variety of object pairs using a large sample. The average correlation was r = .36, and 52 of the 57 object pairs showed a significant positive correlation. Results of multilevel modeling analyses suggested that: (a) implicit and explicit preferences are related, (b) the relationship varies as a function of the objects assessed, and (c) at least four variables moderate the relationship – self-presentation, evaluative strength, dimensionality, and distinctiveness. The variables moderated implicit-explicit correspondence across individuals and accounted for much of the observed variation across content domains. The resulting model of the relationship between automatic and controlled evaluative processes is grounded in personal experience with the targets of evaluation. PMID:16316292

    Food practices are embedded in everyday life and social relationships. In youth nutrition promotion little attention is awarded to this centrality of food practices, yet it may play a pivotal role for young people's overall health and wellbeing beyond the calories food provides. Limited research is available explicitly investigating how food practices affect social relationships. The aim of this synthesis was therefore to find out how young people use everyday food practices to build, strengthen, and negotiate their social relationships. Using a thematic synthesis approach, we analysed 26 qualitative studies exploring young people's food practices. Eight themes provided insight into the ways food practices affected social relationships: caring, talking, sharing, integrating, trusting, reciprocating, negotiating, and belonging. The results showed that young people use food actively to foster connections, show their agency, and manage relationships. This synthesis provides insight into the settings of significance for young people where more research could explore the use of food in everyday life as important for their social relationships. A focus on social relationships could broaden the scope of nutrition interventions to promote health in physical and psychosocial dimensions. Areas for future research are discussed.

  5. Decadal Monsoon-ENSO Relationships Reexamined

    Yun, Kyung-Sook; Timmermann, Axel

    2018-02-01

    The strength of the El Niño-Southern Oscillation (ENSO)-Indian summer monsoon rainfall (ISMR) relationship shows considerable decadal fluctuations, which have been previously linked to low-frequency climatic processes such as shifts in ENSO's center of action or the Atlantic Multidecadal Oscillation. However, random variability can also cause similar variations in the relationship between climate phenomena. Here we propose a statistical test to determine whether the observed time-evolving correlations between ENSO and ISMR are different from those expected from a simple stochastic null hypothesis model. The analysis focuses on the time evolution of moving correlations, their expected variance, and probabilities for rapid transitions. The results indicate that the time evolution of the observed running correlation between these climate modes is indistinguishable from a system in which the ISMR signal can be expressed as a stochastically perturbed ENSO signal. This challenges previous deterministic interpretations. Our results are further corroborated by the analysis of climate model simulations.

    This article investigates the relationship between sharing personal information and relationship development in the context of social networking sites (SNSs). Information disclosed on these sites could affect relationships in a different manner compared to more traditional interactions, such as instant messaging or face-to-face interaction. Respondents in the age range of 12 to 83 were surveyed about experiences of relationship development as a consequence of contact through Facebook or Hyves-the most popular Dutch SNSs. Results showed a primarily positive effect of information sharing on SNSs on our relationships. Furthermore, relationship development mainly occurs among acquaintances and friends, and public posts are most strongly related to relationship development. These findings suggest that SNSs might affect relationships in a distinct fashion as acquaintances and friends gain access to public self-disclosures that might normally only be reserved for close friends and family. Overall, this study provides an insight into some of the positive aspects of the public nature of SNSs in contrast with the general negative associations.

    The book shows why Britain adopted postwar defence policies that entailed nuclear weapon tests, why more than half of these tests were in Australia, where and how they took place, how the two nations cooperated and what was achieved at what cost. The radiation safety standards of the time and of the present day are compared and the safety aspects of the trials are looked at from the contemporary and present day viewpoint. The book covers the five series of trials in Australia and discusses the very special relationship that existed between the United Kingdom and Australia that made them possible. (author)

    2018-03-01

    Full Text Available A recurring problem in healthcare is the high percentage of patients who miss their appointment, be it a consultation or a hospital test. The present study seeks patient’s behavioural patterns that allow predicting the probability of no- shows. We explore the convenience of using Big Data Machine Learning models to accomplish this task. To begin with, a predictive model based only on variables associated with the target appointment is built. Then the model is improved by considering the patient’s history of appointments. In both cases, the Gradient Boosting algorithm was the predictor of choice. Our numerical results are considered promising given the small amount of information available. However, there seems to be plenty of room to improve the model if we manage to collect additional data for both patients and appointments.

    Full Text Available We examined people's charity contributions while in the presence of an observer of the same sex, opposite sex, or no observer. Inspired by costly signaling theory, we hypothesized that men would be more generous in the presence of a potential mate. Men and women played a number of experimental games in which they could earn money. On completion of these games participants were asked what percentage of their earned money they would be willing to donate to charity. Our results show that men contribute more to charity when observed by a member of the opposite sex than by a member of the same sex or no observer. Conversely, female charity donations did not significantly vary across the three observer conditions. Findings support the notion that men's generosity might have evolved as a mating signal.

    2007-01-01

    Bex1 and Calmodulin (CaM) are upregulated during skeletal muscle regeneration. We confirm this finding and demonstrate the novel finding that they interact in a calcium-dependent manner. To study the role of Bex1 and its interaction with CaM in skeletal muscle regeneration, we generated Bex1 knock out (Bex1-KO) mice. These mice appeared to develop normally and are fertile, but displayed a functional deficit in exercise performance compared to wild type (WT) mice. After intramuscular injection of cardiotoxin, which causes extensive and reproducible myotrauma followed by recovery, regenerating muscles of Bex1-KO mice exhibited elevated and prolonged cell proliferation, as well as delayed cell differentiation, compared to WT mice. Thus, our results provide the first evidence that Bex1-KO mice show altered muscle regeneration, and allow us to propose that the interaction of Bex1 with Ca 2+ /CaM may be involved in skeletal muscle regeneration

  15. Fish kidney cells show higher tolerance to hyperosmolality than amphibian

    2018-05-01

    Full Text Available In contrast to fish, amphibians inhabit both aquatic and terrestrial environments. To better understand osmoregulation in fish and amphibian, we have investigated the morphological changes in kidney cells to osmotic stress. To address this, kidney cell line isolated from the freshwater grass carp (CIK and Chinese giant salamander (GSK were challenged to different mediums with distinct osmotic pressures (100, 300 and 700 mOsm. Morphological alterations of the fish and amphibian cells were compared by optical and electron microscopy. Following hyposmotic treatment (100 mOsm, both CIK and GSK cells became unhealthy and show condensed chromatin, swollen mitochondria and cytoplasmic vacuole. Meanwhile, after hyperosmotic treatment (700 mOsm, shrunken CIK cells with multipolar shape, pale or lightly stained cytoplasm, condensed chromatin, vacuoles and swollen mitochondria were detected. GSK cells were seriously damaged and most were completely lysed. The results suggest that fish kidney cells show a higher degree of tolerance to hyperosmoticity by comparing to amphibians and provide novel insights on the osmoregulatory capacity and adaptability of kidney cells between the two animal groups.

  16. Face and body recognition show similar improvement during childhood.

    Adults are proficient in extracting identity cues from faces. This proficiency develops slowly during childhood, with performance not reaching adult levels until adolescence. Bodies are similar to faces in that they convey identity cues and rely on specialized perceptual mechanisms. However, it is currently unclear whether body recognition mirrors the slow development of face recognition during childhood. Recent evidence suggests that body recognition develops faster than face recognition. Here we measured body and face recognition in 6- and 10-year-old children and adults to determine whether these two skills show different amounts of improvement during childhood. We found no evidence that they do. Face and body recognition showed similar improvement with age, and children, like adults, were better at recognizing faces than bodies. These results suggest that the mechanisms of face and body memory mature at a similar rate or that improvement of more general cognitive and perceptual skills underlies improvement of both face and body recognition.

  17. Patterned basal seismicity shows sub-ice stream bedforms

    2017-12-01

    Patterns in seismicity emanating from the bottom of fast-moving ice streams and glaciers may indicate localized patches of higher basal resistance— sometimes called 'sticky spots', or otherwise varying basal properties. These seismogenic basal areas resist an unknown portion of the total driving stress of the Whillans Ice Plain (WIP), in West Antarctica, but may play an important role in the WIP stick-slip cycle and ice stream slowdown. To better understand the mechanism and importance of basal seismicity beneath the WIP, we analyze seismic data collected by a small aperture (micro-earthquakes in Dec 2014, and we compare the resulting map of seismicity to ice bottom depth measured by airborne radar. The number of basal earthquakes per area within the network is spatially heterogeneous, but a pattern of two 400m wide streaks of high seismicity rates is evident, with >50-500 earthquakes detected per 50x50m grid cell in 2 weeks. These seismically active streaks are elongated approximately in the ice flow direction with a spacing of 750m. Independent airborne radar measurements of ice bottom depth from Jan 2013 show a low-amplitude ( 5m) undulation in the basal topography superposed on a regional gradient in ice bottom depth. The flow-perpendicular wavelength of these low-amplitude undulations is comparable to the spacing of the high seismicity bands, and the streaks of high seismicity intersect local lows in the undulating basal topography. We interpret these seismic and radar observations as showing seismically active sub-ice stream bedforms that are low amplitude and elongated in the direction of ice flow, comparable to the morphology of mega scale glacial lineations (MSGLs), with high basal seismicity rates observed in the MSGL troughs. These results have implications for understanding the formation mechanism of MSGLS and well as understanding the interplay between basal topographic roughness, spatially varying basal till and hydrologic properties, basal

    2013-01-01

    We propose and test a model connecting women's attachment styles, intimate relationship quality, workplace supervisor relationships, and well-being. The factors that lead to women's successful interaction patterns at home with a partner are suggested to be similar to successful interactions at work and are suggested to be related to well-being. A model was tested with data from 209 working women across various U.S. organizations. Women with an avoidance attachment style tended to have intimate relationships that were low in satisfaction and cohesion as well as low-quality relationships with their supervisors. Women in cohesive intimate relationships were likely to be satisfied with their job, experience low conflict at work, and report few physical symptoms. Women who had quality relationships with their superiors also had low conflict at work and were satisfied with their jobs. Results show important associations among social relationships at home and work related to quality of life.

    Objective: We aimed to detect the frequency of restricted diffusion in intracerebral metastases and to find whether there is correlation between the primary tumor pathology and diffusion-weighted MR imaging (DWI) findings of these metastases. Material and methods: 87 patients with intracerebral metastases were examined with routine MR imaging and DWI. 11 hemorrhagic metastatic lesions were excluded. The routine MR imaging included three plans before and after contrast enhancement. The DWI was performed with spin-echo EPI sequence with three b values (0, 500 and 1000), and ADC maps were calculated. 76 patients with metastases were grouped according to primary tumor histology and the ratios of restricted diffusion were calculated according to these groups. ADCmin values were measured within the solid components of the tumors and the ratio of metastases with restricted diffusion to that which do not show restricted diffusion were calculated. Fisher's exact and Mann-Whitney U tests were used for the statistical analysis. Results: Restricted diffusion was observed in a total of 15 metastatic lesions (19, 7%). Primary malignancy was lung carcinoma in 10 of these cases (66, 6%) (5 small cell carcinoma, 5 non-small cell carcinoma), and breast carcinoma in three cases (20%). Colon carcinoma and testicular teratocarcinoma were the other two primary tumors in which restricted diffusion in metastasis was detected. There was no statistical significant difference between the primary pathology groups which showed restricted diffusion (p > 0.05). ADCmin values of solid components of the metastasis with restricted diffusion and other metastasis without restricted diffusion also showed no significant statistical difference (0.72 {+-} 0.16 x 10{sup -3} mm{sup 2}/s and 0.78 {+-} 21 x 10{sup -3} mm{sup 2}/s respectively) (p = 0.325). Conclusion: Detection of restricted diffusion on DWI in intracerebral metastasis is not rare, particularly if the primary tumor is lung or breast

  7. Inferring relationships between pairs of individuals from locus heterozygosities

    2002-11-01

    Full Text Available Abstract Background The traditional exact method for inferring relationships between individuals from genetic data is not easily applicable in all situations that may be encountered in several fields of applied genetics. This study describes an approach that gives affordable results and is easily applicable; it is based on the probabilities that two individuals share 0, 1 or both alleles at a locus identical by state. Results We show that these probabilities (zi depend on locus heterozygosity (H, and are scarcely affected by variation of the distribution of allele frequencies. This allows us to obtain empirical curves relating zi's to H for a series of common relationships, so that the likelihood ratio of a pair of relationships between any two individuals, given their genotypes at a locus, is a function of a single parameter, H. Application to large samples of mother-child and full-sib pairs shows that the statistical power of this method to infer the correct relationship is not much lower than the exact method. Analysis of a large database of STR data proves that locus heterozygosity does not vary significantly among Caucasian populations, apart from special cases, so that the likelihood ratio of the more common relationships between pairs of individuals may be obtained by looking at tabulated zi values. Conclusions A simple method is provided, which may be used by any scientist with the help of a calculator or a spreadsheet to compute the likelihood ratios of common alternative relationships between pairs of individuals.

  9. Management in a neotropical show cave: planning for invertebrates conservation

    Full Text Available Lapa Nova is a dolomitic cave about 4.5 km long located in northwestern Minas Gerais state, Brazil. The cave experiences intense tourism, concentrated over a single period of the year, during the Feast of Our Lady of Lapa. In order to evaluate the impacts felt by the invertebrate community from this tourism, a new methodology was proposed. Four types of areas (intense visitation area, outlying visitation areas, moderate visitation areas and no-visitation areas were sampled for invertebrates. There was one sampling prior and another on the last day of the 128th feast, to evaluate the effects of visitation on cave-dwelling invertebrates. Results show that invertebrate populations residing in more intensely visited areas of the cave undergo changes in distribution following the event. As a consequence of tourism, invertebrates shift to outlying locations from the visited area, which serve as refuges to the communities. Apparently, the fact that there are places inside Lapa Nova inaccessible to tourists reduces the impact suffered by the invertebrate community, as those sites serve as refuges for cave-dwelling organisms during the pilgrimage. A proper management plan was devised for the tourism/religious use of the cave. It consists basically of delimiting marked pathways for tourists, allowing invertebrates to seek shelter at locations outside visited areas and keeping no-visitation areas off-limits to tourism based on the results of the visitation effects on cave-dwelling invertebrates.

    Vehicle combustion and component wear are a major source of metal contamination in the environment, which could be especially concerning where road ditches are actively farmed. The objective of this study was to assess how site variables, namely age, traffic (vehicles day(-1)), and percent carbon (%C) affect metal accumulation in roadside soils. A soil chronosequence was established with sites ranging from 3 to 37 years old and bioavailable, or mobile, concentrations of Zinc (Zn) and Copper (Cu) were measured along major highways in North Carolina using a Mehlich III extraction. Mobile Zn and Cu concentrations were low overall, and when results were scaled via literature values to "total metal", the results were still generally lower than previous roadside studies. This could indicate farming on lands near roads would pose a low plant toxicity risk. Zinc and Cu were not correlated with annual average traffic count, but were positively correlated with lifetime traffic load (the product of site age and traffic count). This study shows an often overlooked variable, site age, should be included when considering roadside pollution accumulation. Zinc and Cu were more strongly associated with %C, than traffic load. Because vehicle combustion is also a carbon source, it is not obvious whether the metals and carbon are simply co-accumulating or whether the soil carbon in roadside soils may facilitate previously overlooked roles in sequestering metals on-site.

    The fragrance terpene R-limonene is a very weak sensitizer, but forms allergenic oxidation products upon contact with air. The primary oxidation products of oxidized limonene, the hydroperoxides, have an important impact on the sensitizing potency of the oxidation mixture. One analogue, limonene-1-hydroperoxide, was experimentally shown to be a significantly more potent sensitizer than limonene-2-hydroperoxide in the local lymph node assay with non-pooled lymph nodes. To investigate the pattern of reactivity among consecutive dermatitis patients to two structurally closely related limonene hydroperoxides, limonene-1-hydroperoxide and limonene-2-hydroperoxide. Limonene-1-hydroperoxide, limonene-2-hydroperoxide, at 0.5% in petrolatum, and oxidized limonene 3.0% pet. were tested in 763 consecutive dermatitis patients. Of the tested materials, limonene-1-hydroperoxide gave most reactions, with 2.4% of the patients showing positive patch test reactions. Limonene-2-hydroperoxide and oxidized R-limonene gave 1.7% and 1.2% positive patch test reactions, respectively. Concomitant positive patch test reactions to other fragrance markers in the baseline series were frequently noted. The results are in accordance with the experimental studies, as limonene-1-hydroperoxide gave more positive patch test reactions in the tested patients than limonene-2-hydroperoxide. Furthermore, the results support the specificity of the allergenic activity of the limonene hydroperoxide analogues and the importance of oxidized limonene as a cause of contact allergy. © 2014 John Wiley & Sons A/S.

    Thyroid follicular adenomas and adenomatous thyroid nodules are a frequent finding in geographical areas with iodine deficiency. They occur as hypofunctioning (scintigraphically cold) or hyperfunctioning (scintigraphically hot) nodules. Their predominant clonal origin suggests that they result from clonal expansion of a single cell, which is very likely the result of a prolonged increase in proliferation compared with non-affected surrounding cells. To test whether increased cell proliferation is detectable in cold thyroid nodules, we studied paraffin-embedded tissue from 40 cold thyroid nodules and their surrounding normal thyroid tissue for the occurrence of the proliferating cell nuclear antigen (PCNA) and Ki-67 (MIB-1 antibody) epitopes as markers for cell proliferation. All 40 thyroid nodules were histologically well characterized and have been studied for molecular characteristics before. The labeling index (number of labeled cells versus total cell number) for nodular and surrounding tissue was calculated. In 33 cold thyroid nodules a significant (p thyroid nodules a significant (p thyroid epithelial cell proliferation is a uniform feature common to most cold nodules. However, the increase of proliferation markers shows a heterogeneity that is not correlated with histopathologic, molecular, or clinical characteristics.

    Full Text Available Objectives: The role of leisure-time physical activity in reducing all-cause and cardiovascular mortality is well explored. The knowledge on occupational and commuting physical activity continues to be ambiguous and misleading. The aim of the study is to assess the influence of different kinds of physical activity on cardiovascular mortality risk in men. Material and Methods: Data analysis on physical activity level and other selected cardiovascular risk factors acquired from 3577 men in the age between 50–80 years who participated in the National Multicenter Health Survey WOBASZ (Wieloośrodkowe Ogólnopolskie Badanie Stanu Zdrowia, Poland (2003–2005 was linked with male mortality in 2004–2009. Data about causes of deaths were obtained from the Central Statistical Office and the Population Electronic Register. Results: Among males aged 50–59 years, the strongest risk factor was living in large settlements and provincial capitals as a place of residence and the most protective factor was occupational physical activity. In the age group 60–69 years and 70–80 years, the strongest protective effect was observed for leisure-time physical activity. In men aged between 70–80 years (unlike in the 50–59 years age group, the protective effect of large settlements and provincial capitals as a place of residence was noted. Conclusions: Occupational physical activity significantly reduced cardiovascular mortality in men aged 50–69 years, while for leisure-time activity the positive effect was observed in age group 60–69 years and 70–80 years. On the other hand, for the inhabitants of large settlements and provincial capitals, significantly higher risk of cardiovascular mortality in the age group 50–69 years and lower risk in the age group ≥ 70 years was noted, both in comparison with smaller places of residence.

    The purpose of this study was to examine the effectiveness of an interpersonal relationship program on interpersonal relationships, self-esteem, and depression in nursing students. This was a quasi-experiment with a nonequivalent control group pre-posttest design. Sixty-four nursing students participated in the study with 31 in the experimental group and 33 in the control group. They were from 3 different colleges of nursing located in Seoul. The interpersonal relationship program was held 10 times over 10 weeks, taking 90 minutes per session. The interpersonal relationship change scale developed by Schlein and Guemey, Rosenberg's self-esteem scale, and CED-S for depression were the instruments used in the study. The data collection period was from January 4 to March 8, 2011, and the collected data were analyzed with SPSS 14.0 using the Χ(2)-test, t-test, and paired t-test. The results showed a significant difference between the experimental group and the control group in terms of the degree of interpersonal relationships, self-esteem, and depression. The results indicate that interpersonal relationship programs have positive effects for improving interpersonal relationships and self-esteem, and decreasing depression in nursing students.

    Full Text Available Although the 2015 Dietary Guidelines Advisory Committee concluded that there was moderate evidence that substituting sugar-containing sweeteners with low-calorie sweeteners (LCS reduces calorie intake and weight, dietary recommendations encourage substituting only water for sugar-sweetened beverages during weight management. This cross-sectional study evaluated the relation of water and no- and low-calorie sweetened beverage (LCSB intake with nutrient intakes and prediabetes criteria using data from the National Health and Nutrition Examination Survey (NHANES 2001–2012 in 25,817 adults that were free of diabetes. Although linear trends were observed with both beverages, higher LCSB intake was associated with significantly lower consumption of carbohydrates (−9.1 g/day vs. −1.4 g/day, total sugars (−10.9 g/day vs. −2.2 g/day, and added sugars (−2.0 tsp eq vs. −0.8 tsp eq than those associated with higher water intake. Higher intake of both beverages was significantly associated with lower insulin levels (p < 0.01; however, higher intake of LCSB was also associated with lower hemoglobin A1c (HbA1c and lower homeostatic model assessment of insulin resistance (HOMA-IR (p < 0.01. We observed lower odds ratios for elevated HbA1c (adjusted odds ratio [OR] 0.79, 95% CI 0.64–0.98, HOMA-IR (0.68, 0.53–0.87, and insulin levels (0.63, 0.49–0.80 in LCSB among the higher (2+ servings intake group compared to the lowest (<1 serving intake group. Contrary to conventional wisdom, LCSB consumption was associated with equal, if not better, dietary intake and glycemic response than water consumption. Although observational in nature, these results contribute to the growing body of evidence from human studies suggesting that in addition to water, LCSBs can also be sensible choices for reducing sugars and carbohydrate intake, with no adverse associations to measures of glycemic response.

    Purpose: As Baby Boomers enter late life, relationships with family members gain importance. This review article highlights two aspects of their intergenerational relationships: (a) caregiving for aging parents and (b) interactions with adult children in the context of changing marital dynamics. Design and Methods: The researchers describe three studies: (a) the Within Family Differences Study (WFDS) of mothers aged 65–75 and their multiple grown children (primarily Baby Boomers) ongoing since 2001; (b) the Family Exchanges Study (FES) of Baby Boomers aged 42–60, their spouses, parents, and multiple grown children ongoing since 2008; and (c) the Longitudinal Study of Generations (LSoG) of 351 three-generation families started when the Baby Boomers were teenagers in 1971, with interviews every 3–5 years from 1985 to 2005. Results: These studies show that the Baby Boomers in midlife navigate complex intergenerational patterns. The WFDS finds aging parents differentiate among Baby Boomer children in midlife, favoring some more than others. The FES shows that the Baby Boomers are typically more involved with their children than with their aging parents; Boomers’ personal values, family members’ needs, and personal rewards shape decisions about support. The LSoG documents how divorce and remarriage dampen intergenerational obligations in some families. Moreover, loosening cultural norms have weakened family bonds in general. Implications: Reviews of these studies provide insights into how the Baby Boomers may negotiate caregiving for aging parents as well as the likelihood of family care they will receive when their own health declines in the future.

    The gene Prestin encodes a motor protein that is thought to confer the high-frequency sensitivity and selectivity that characterizes the mammalian auditory system. Recent research shows that the Prestin gene has undergone a burst of positive selection on the ancestral branch of the Old World horseshoe and leaf-nosed bats (Rhinolophidae and Hipposideridae, respectively), and also on the branch leading to echolocating cetaceans. Moreover, these two groups share a large number of convergent amino acid sequence replacements. Horseshoe and leaf-nosed bats exhibit narrowband echolocation, in which the emitted calls are based on the second harmonic of a predominantly constant frequency (CF) component, the frequency of which is also over-represented in the cochlea. This highly specialized form of echolocation has also evolved independently in the neotropical Parnell's mustached bat (Pteronotus parnellii). To test whether the convergent evolution of CF echolocation between lineages has arisen from common changes in the Prestin gene, we sequenced the Prestin coding region (~2,212 bp, >99% coverage) in P. parnellii and several related species that use broadband echolocation calls. Our reconstructed Prestin gene tree and amino acid tree showed that P. parnellii did not group together with Old World horseshoe and leaf-nosed bats, but rather clustered within its true sister species. Comparisons of sequences confirmed that P. parnellii shared most amino acid changes with its congeners, and we found no evidence of positive selection in the branch leading to the genus of Pteronotus. Our result suggests that the adaptive changes seen in Prestin in horseshoe and leaf-nosed bats are not necessary for CF echolocation in P. parnellii.

    Full Text Available Parents play a key role in the emotional development of child especially in preschool age. There are many related factors in the relationship of child and parent. It is important to understand children’s subjective experiences with their parents. Temperamental characteristics of the mother have an important role to play in the quality of this relationship. Most parents desire to have deep, intimate relationships between their children. Also, children need emo-tional closeness, safety and security. Attachment is the strong emotional bond that develops between child and primary caregiver. The secure attachment style increases the emotional development of child positively and it may serve as a protective factor for psychological well-being. Children’s well-being often depends on how children perceive or interpret their parents behaviors. Poor parenting practices represent some of the most risk factors for psychological problems in childhood. There are many research results show that correlation between the parental negative attitudes and the psychopathology of the children. The present study aimed to review the relationship between parent and preschool children.

    The Russian-American Gallium solar neutrino Experiment (SAGE) is described. The solar neutrino flux measured by 31 extractions through October, 1993 is presented. The result of 69+/-10(stat)+5/-7(syst) SNU is to be compared with a Standard Solar Model prediction of 132 SNU. The initial results of a measurement of experimental efficiencies are also discussed by exposing the gallium target to neutrinos from an artificial source. The capture rate of neutrinos from this source is very close to that which is expected. The result can be expressed as a ratio of the measured capture rate to the anticipated rate from the source activity. This ratio is 0.93+0.15, -0.17 where the systematic and statistical errors have been combined. To first order the experimental efficiencies are in agreement with those determined during solar neutrino measurements and in previous auxiliary measurements. One must conclude that the discrepancy between the measured solar neutrino flux and that predicted by the solar models can not arise from an experimental artifact. (author)

    Full Text Available Hanseniaspora uvarum is one of the most abundant yeast species found on grapes and in grape must, at least before the onset of alcoholic fermentation which is usually performed by Saccharomyces species. The aim of this study was to characterise the genetic and phenotypic variability within the H. uvarum species. One hundred and fifteen strains isolated from winemaking environments in different geographical origins were analysed using 11 microsatellite markers and a subset of 47 strains were analysed by AFLP. H. uvarum isolates clustered mainly on the basis of their geographical localisation as revealed by microsatellites. In addition, a strong clustering based on year of isolation was evidenced, indicating that the genetic diversity of Hanseniaspora uvarum isolates was related to both spatial and temporal variations. Conversely, clustering analysis based on AFLP data provided a different picture with groups showing no particular characteristics, but provided higher strain discrimination. This result indicated that AFLP approaches are inadequate to establish the genetic relationship between individuals, but allowed good strain discrimination. At the phenotypic level, several extracellular enzymatic activities of enological relevance (pectinase, chitinase, protease, β-glucosidase were measured but showed low diversity. The impact of environmental factors of enological interest (temperature, anaerobia and copper addition on growth was also assessed and showed poor variation. Altogether, this work provided both new analytical tool (microsatellites and new insights into the genetic and phenotypic diversity of H. uvarum, a yeast species that has previously been identified as a potential candidate for co-inoculation in grape must, but whose intraspecific variability had never been fully assessed.

  8. Pumilio2-deficient mice show a predisposition for epilepsy

    2017-11-01

    Full Text Available Epilepsy is a neurological disease that is caused by abnormal hypersynchronous activities of neuronal ensembles leading to recurrent and spontaneous seizures in human patients. Enhanced neuronal excitability and a high level of synchrony between neurons seem to trigger these spontaneous seizures. The molecular mechanisms, however, regarding the development of neuronal hyperexcitability and maintenance of epilepsy are still poorly understood. Here, we show that pumilio RNA-binding family member 2 (Pumilio2; Pum2 plays a role in the regulation of excitability in hippocampal neurons of weaned and 5-month-old male mice. Almost complete deficiency of Pum2 in adult Pum2 gene-trap mice (Pum2 GT causes misregulation of genes involved in neuronal excitability control. Interestingly, this finding is accompanied by the development of spontaneous epileptic seizures in Pum2 GT mice. Furthermore, we detect an age-dependent increase in Scn1a (Nav1.1 and Scn8a (Nav1.6 mRNA levels together with a decrease in Scn2a (Nav1.2 transcript levels in weaned Pum2 GT that is absent in older mice. Moreover, field recordings of CA1 pyramidal neurons show a tendency towards a reduced paired-pulse inhibition after stimulation of the Schaffer-collateral-commissural pathway in Pum2 GT mice, indicating a predisposition to the development of spontaneous seizures at later stages. With the onset of spontaneous seizures at the age of 5 months, we detect increased protein levels of Nav1.1 and Nav1.2 as well as decreased protein levels of Nav1.6 in those mice. In addition, GABA receptor subunit alpha-2 (Gabra2 mRNA levels are increased in weaned and adult mice. Furthermore, we observe an enhanced GABRA2 protein level in the dendritic field of the CA1 subregion in the Pum2 GT hippocampus. We conclude that altered expression levels of known epileptic risk factors such as Nav1.1, Nav1.2, Nav1.6 and GABRA2 result in enhanced seizure susceptibility and manifestation of epilepsy in the

    Full Text Available Abstract: Although the relationship between perceptual motor skills and attention is reported in the literature, few studies have empirically explored this association. Thus, the objective of this study was to investigate the relationship between these constructs, using the Bender-Gestalt Test: Gradual Scoring System (B-SPG and the Psychological Battery for Attention Assessment (BPA. The participants were 320 children from four public schools in a city located in the South of the state of Minas Gerais, with ages ranging from seven to 10 years (M = 8.39, SD = 1.10 and 196 (55.9 % female. The results showed negative, moderate and significant correlations between the total scores of the instruments, indicating the relationship between the constructs. Although the data has confirmed the existence of a relationship between perceptual motor skills and attention, further studies with samples from other regions are necessary.

    Mirror self-recognition (MSR), i.e., the ability to recognize oneself in a mirror, is considered a potential index of self-recognition and the foundation of individual development. A wealth of literature on MSR is available for social animals, such as chimpanzees, Asian elephants and dolphins, yet little is known about MSR in solitary mammalian species. We aimed to evaluate whether the giant panda can recognize itself in the mirror, and whether this capacity varies with age. Thirty-four captive giant pandas (F:M = 18:16; juveniles, sub-adults and adults) were subjected to four mirror tests: covered mirror tests, open mirror tests, water mark control tests, and mark tests. The results showed that, though adult, sub-adult and juvenile pandas exposed to mirrors spent similar amounts of time in social mirror-directed behaviors (χ(2) = 0.719, P = 0.698), none of them used the mirror to touch the mark on their head, a self-directed behavior suggesting MSR. Individuals of all age groups initially displayed attacking, threatening, foot scraping and backwards walking behaviors when exposed to their self-images in the mirror. Our data indicate that, regardless of age, the giant pandas did not recognize their self-image in the mirror, but instead considered the image to be a conspecific. Our results add to the available information on mirror self-recognition in large mammals, provide new information on a solitary species, and will be useful for enclosure design and captive animal management.

    Full Text Available OBJECTIVE: Evaluate whether exhaled nitric oxide may serve as a marker of intraoperative bronchospasm. INTRODUCTION: Intraoperative bronchospasm remains a challenging event during anesthesia. Previous studies in asthmatic patients suggest that exhaled nitric oxide may represent a noninvasive measure of airway inflammation. METHODS: A total of 146,358 anesthesia information forms, which were received during the period from 1999 to 2004, were reviewed. Bronchospasm was registered on 863 forms. From those, three groups were identified: 9 non-asthmatic patients (Bronchospasm group, 12 asthmatics (Asthma group and 10 subjects with no previous airway disease or symptoms (Control group. All subjects were submitted to exhaled nitric oxide measurements (parts/billion, spirometry and the induced sputum test. The data was compared by ANOVA followed by the Tukey test and Kruskal-Wallis followed by Dunn's test. RESULTS: The normal lung function test results for the Bronchospasm group were different from those of the asthma group (p <0.05. The median percentage of eosinophils in induced sputum was higher for the Asthma [2.46 (0.45-6.83] compared with either the Bronchospasm [0.55 (0-1.26] or the Control group [0.0 (0] (p <0.05; exhaled nitric oxide followed a similar pattern for the Asthma [81.55 (57.6-86.85], Bronchospasm [46.2 (42.0 -62.6] and Control group [18.7 (16.0-24.7] (p< 0.05. CONCLUSIONS: Non-asthmatic patients with intraoperative bronchospasm detected during anesthesia and endotracheal intubation showed increased expired nitric oxide.

    Through domestication and co-evolution with humans, dogs have developed abilities to attract human attention, e.g. in a manner of seeking assistance when faced with a problem solving task. The aims of this study were to investigate within breed variation in human-directed contact seeking in dogs and to estimate its genetic basis. To do this, 498 research beagles, bred and kept under standardized conditions, were tested in an unsolvable problem task. Contact seeking behaviours recorded included both eye contact and physical interactions. Behavioural data was summarized through a principal component analysis, resulting in four components: test interactions, social interactions, eye contact and physical contact. Females scored significantly higher on social interactions and physical contact and age had an effect on eye contact scores. Narrow sense heritabilities (h(2) ) of the two largest components were estimated at 0.32 and 0.23 but were not significant for the last two components. These results show that within the studied dog population, behavioural variation in human-directed social behaviours was sex dependent and that the utilization of eye contact seeking increased with age and experience. Hence, heritability estimates indicate a significant genetic contribution to the variation found in human-directed social interactions, suggesting that social skills in dogs have a genetic basis, but can also be shaped and enhanced through individual experiences. This research gives the opportunity to further investigate the genetics behind dogs' social skills, which could also play a significant part into research on human social disorders such as autism. © 2015 John Wiley & Sons Ltd and International Behavioural and Neural Genetics Society.

    Vehicle combustion and component wear are a major source of metal contamination in the environment, which could be especially concerning where road ditches are actively farmed. The objective of this study was to assess how site variables, namely age, traffic (vehicles day"−"1), and percent carbon (%C) affect metal accumulation in roadside soils. A soil chronosequence was established with sites ranging from 3 to 37 years old and bioavailable, or mobile, concentrations of Zinc (Zn) and Copper (Cu) were measured along major highways in North Carolina using a Mehlich III extraction. Mobile Zn and Cu concentrations were low overall, and when results were scaled via literature values to “total metal”, the results were still generally lower than previous roadside studies. This could indicate farming on lands near roads would pose a low plant toxicity risk. Zinc and Cu were not correlated with annual average traffic count, but were positively correlated with lifetime traffic load (the product of site age and traffic count). This study shows an often overlooked variable, site age, should be included when considering roadside pollution accumulation. Zinc and Cu were more strongly associated with %C, than traffic load. Because vehicle combustion is also a carbon source, it is not obvious whether the metals and carbon are simply co-accumulating or whether the soil carbon in roadside soils may facilitate previously overlooked roles in sequestering metals on-site. - Highlights: • Low plant available zinc and copper concentrations in roadside soils of the southeast U.S. • Metals from vehicular traffic may not be adversely affecting plants in roadside environment. • Traffic volume and site age better predictor of metal pollution than traffic volume alone. - Mobile concentrations of Zn and Cu in roadside soils were below toxic levels. Zn and Cu concentrations were better correlated with lifetime vehicle load, as opposed to traffic volume.

    Drawings can be ambiguous and represent more than one entity. In three experiments, we examine whether young children show representational flexibility by allowing one picture to be called by a second name. We also evaluate the hypothesis that children who are representationally flexible see the artist's intention as binding, rather than changeable. In Experiment 1, an artist declared what she intended to draw (e.g. a balloon) but then produced an ambiguous drawing. Children were asked whether the drawings could be interpreted differently (e.g. 'could this be a lollipop?') in the presence of a perceptually similar or dissimilar distractor (e.g., lollipop or snake). Six-year-olds accepted two labels for drawings in both conditions, but four-year-olds only did so in the dissimilar condition. Experiment 2 probed each possible interpretation more deeply by asking property questions (e.g., 'does it float?, does it taste good?'). Preschoolers who understood that the ambiguous drawing could be given two interpretations nevertheless mostly endorsed only properties associated with the prior intent. Experiment 3 provided converging evidence that 4-year-olds were representationally flexible using a paradigm that did not rely upon modal questioning. Taken together, our results indicate that even 4-year-olds understand that pictures may denote more than one referent, they still think of the symbol as consistent with the artist's original intention.

    The Southeast Pacific is characterized by rich upwelling systems that have sustained and been impacted by human groups for at least 12 ka. Recent fishing and aquaculture practices have put a strain on productive coastal ecosystems from Tongoy Bay, in north-central Chile. We use a temporal baseline to determine whether potential changes to community structure and composition over time are due to anthropogenic factors, natural climatic variations or both. We compiled a database ( n  = 33 194) with mollusc species abundances from the Mid-Pleistocene, Late Pleistocene, Holocene, dead shell assemblages and live-sampled communities. Species richness was not significantly different, neither were diversity and evenness indices nor rank abundance distributions. There is, however, an increase in relative abundance for the cultured scallop Argopecten , while the previously dominant clam Mulinia is locally very rare. Results suggest that impacts from both natural and anthropogenic stressors need to be better understood if benthic resources are to be preserved. These findings provide the first Pleistocene temporal baseline for the south Pacific that shows that this highly productive system has had the ability to recover from past alterations, suggesting that if monitoring and management practices continue to be implemented, moderately exploited communities from today have hopes for recovery.

    An intriguing question in behavioral biology is whether consistent individual differences (called animal personalities) relate to variation in cognitive performance because commonly measured personality traits may be associated with risk-reward trade-offs.Social insects,whose learning abilities have been extensively characterized,show consistent behavioral variability,both at colony and at individual level.We investigated the possible link between personality traits and learning performance in the carpenter ant Camponotus aethiops.Exploratory activity,sociability,and aggression were assessed twice in ant foragers.Behaviors differed among individuals,they were partly repeatable across time and exploratory activity correlated positively with aggression.Learning abilities were quantified by differential conditioning of the maxilla-labium extension response,a task that requires cue perception and information storage.We found that exploratory activity of individual ants significantly predicted learning performance:"active-explorers" were slower in learning the task than "inactive-explorers".The results suggest for the first time a link between a personality trait and cognitive performance in eusocial insects,and that the underlying individual variability could affect colony performance and success.

    The protozoan parasite Trypanosoma brucei causes human African trypanosomiasis, or sleeping sickness, a neglected tropical disease that requires new, safer, and more effective treatments. Repurposing oral drugs could reduce both the time and cost involved in sleeping sickness drug discovery. Tafenoquine (TFQ) is an oral antimalarial drug belonging to the 8-aminoquinoline family which is currently in clinical phase III. We show here that TFQ efficiently kills different T. brucei spp. in the submicromolar concentration range. Our results suggest that TFQ accumulates into acidic compartments and induces a necrotic process involving cell membrane disintegration and loss of cytoplasmic content, leading to parasite death. Cell lysis is preceded by a wide and multitarget drug action, affecting the lysosome, mitochondria, and acidocalcisomes and inducing a depolarization of the mitochondrial membrane potential, elevation of intracellular Ca(2+), and production of reactive oxygen species. This is the first report of an 8-aminoquinoline demonstrating significant in vitro activity against T. brucei. Copyright © 2015, American Society for Microbiology. All Rights Reserved.

    Grooming handclasp (GHC) behaviour was originally advocated as the first evidence of social culture in chimpanzees owing to the finding that some populations engaged in the behaviour and others do not. To date, however, the validity of this claim and the extent to which this social behaviour varies between groups is unclear. Here, we measured (i) variation, (ii) durability and (iii) expansion of the GHC behaviour in four chimpanzee communities that do not systematically differ in their genetic backgrounds and live in similar ecological environments. Ninety chimpanzees were studied for a total of 1029 h; 1394 GHC bouts were observed between 2010 and 2012. Critically, GHC style (defined by points of bodily contact) could be systematically linked to the chimpanzee's group identity, showed temporal consistency both within and between groups, and could not be accounted for by the arm-length differential between partners. GHC has been part of the behavioural repertoire of the chimpanzees under study for more than 9 years (surpassing durability criterion) and spread across generations (surpassing expansion criterion). These results strongly indicate that chimpanzees' social behaviour is not only motivated by innate predispositions and individual inclinations, but may also be partly cultural in nature.

    Social networking sites (SNS) play an increasingly important role in maintaining geographically close romantic relationships (GCRR). However, knowledge about SNS use in long-distance romantic relationships (LDRR) is still lacking. The present study examined the relative importance of SNS in maintaining LDRR compared to GCRR, particularly with regard to the use of SNS to express involvement (via relational maintenance behaviors) and to gauge a partner's involvement (via partner surveillance and jealousy) in the relationship. An online survey was conducted among predominantly young adult Facebook users who were in a romantic relationship (N=272). Results showed that participants who were in a LDRR reported higher levels of relational maintenance behaviors through SNS than participants who were in a GCRR. Also, as compared to participants who were in a GCRR, participants who were in a LDRR used SNS more for partner surveillance and experienced higher levels of SNS jealousy.

    Full Text Available Mental time travel refers to the ability to recall episodic past and imagine future events. The present study aimed to investigate cultural differences in mental time travel between Chinese and Australian university students. A total of 231 students (108 Chinese & 123 Australians participated in the study. Their mental time travel abilities were measured by the Sentence Completion for Events from the Past Test (SCEPT and the Sentence Completion for Events in the Future Test (SCEFT. Results showed that there were no cultural differences in the number of specific events generated for the past or future. Significant differences between the Chinese and Australian participants were found mainly in the emotional valence and content of the events generated. Both Chinese and Australian participants generated more specific positive events compared to negative events when thinking about the future and Chinese participants were more positive about their past than Australian participants when recalled specific events. For content, Chinese participants recalled more events about their interpersonal relationships, while Australian participants imagined more about personal future achievements. These findings shed some lights on cultural differences in episodic past and future thinking.

    The United States is beginning to appreciate the value of having massive oil sands resources located in relatively close proximity to their northern border. This article discussed a recent study conducted by the Canadian Energy Research Institute (CERI) to assess the impact of Canada's oil sands development on the economy of the United States. The study forecasted that the demand for oil sands-related goods and services from American companies will continue to increase as the industry expands. The top national-level goods and services impacts will be derived from increases in manufacturing; finance; insurance; real estate; and professional, scientific, and technical services. Accommodation and food services in the United States will also benefit from the growth of the oil sands industry. The United States may not risk pushing ahead with strict carbon-cutting legislation targeting the oil sands when policy-makers consider the potential impacts of Canada selling its resources to China. 1 fig.

    While the supply of freshwater is expected to decline in many regions in the coming decades, invasive plant species, often 'high water spenders', are greatly expanding their ranges worldwide. In this study, we quantified the ecohydrological differences between native and invasive trees and also the effects of woody invasive removal on plot-level water use in a heavily invaded mono-dominant lowland wet tropical forest on the Island of Hawaii. We measured transpiration rates of co-occurring native and invasive tree species with and without woody invasive removal treatments. Twenty native Metrosideros polymorpha and 10 trees each of three invasive species, Cecropia obtusifolia, Macaranga mappa and Melastoma septemnervium, were instrumented with heat-dissipation sap-flux probes in four 100 m(2) plots (two invaded, two removal) for 10 months. In the invaded plots, where both natives and invasives were present, Metrosideros had the lowest sap-flow rates per unit sapwood, but the highest sap-flow rates per whole tree, owing to its larger mean diameter than the invasive trees. Stand-level water use within the removal plots was half that of the invaded plots, even though the removal of invasives caused a small but significant increase in compensatory water use by the remaining native trees. By investigating the effects of invasive species on ecohydrology and comparing native vs. invasive physiological traits, we not only gain understanding about the functioning of invasive species, but we also highlight potential water-conservation strategies for heavily invaded mono-dominant tropical forests worldwide. Native-dominated forests free of invasive species can be conservative in overall water use, providing a strong rationale for the control of invasive species and preservation of native-dominated stands.

    Generous coverage of specialty drugs for cancer and other diseases may be valuable not only for sick patients currently using these drugs, but also for healthy people who recognize the potential need for them in the future. This study estimated how healthy people value insurance coverage of specialty drugs, defined as high-cost drugs that treat cancer and other serious health conditions like multiple sclerosis, by quantifying willingness to pay via a survey. US adults were estimated to be willing to pay an extra $12.94 on average in insurance premiums per month for generous specialty-drug coverage--in effect, $2.58 for every dollar in out-of-pocket costs that they would expect to pay with a less generous insurance plan. Given the value that people assign to generous coverage of specialty drugs, having high cost sharing on these drugs seemingly runs contrary to what people value in their health insurance.

  14. Can recurrence networks show small-world property?

    Recurrence networks are complex networks, constructed from time series data, having several practical applications. Though their properties when constructed with the threshold value ϵ chosen at or just above the percolation threshold of the network are quite well understood, what happens as the threshold increases beyond the usual operational window is still not clear from a complex network perspective. The present Letter is focused mainly on the network properties at intermediate-to-large values of the recurrence threshold, for which no systematic study has been performed so far. We argue, with numerical support, that recurrence networks constructed from chaotic attractors with ϵ equal to the usual recurrence threshold or slightly above cannot, in general, show small-world property. However, if the threshold is further increased, the recurrence network topology initially changes to a small-world structure and finally to that of a classical random graph as the threshold approaches the size of the strange attractor. - Highlights: • Properties of recurrence networks at intermediate-to-large values of recurrence threshold are analyzed from a complex network perspective. • Using a combined plot of characteristic path length and clustering coefficient, it is shown that the recurrence network constructed with recurrence threshold equal to or just above the percolation threshold cannot, in general, display small-world property. • As the recurrence threshold is increased from its usual operational window, the resulting network makes a smooth transition initially to a small-world network for an intermediate range of thresholds and finally to the classical random graph as the threshold becomes comparable to the size of the attractor.

    Full Text Available The aim of this paper is to examine whether the First Law of Petropolitics denominated by Friedman in 2006 is valid for OPEC countries. To do this, this paper analyses the relationship between political risk and oil supply by applying the asymmetric panel causality test suggested by Hatemi-J (2011 to these countries for the period 1984-2014. The results show that the First Law of Petropolitics is valid for Angola, Iraq, Kuwait, Libya, Nigeria, Qatar, Saudi Arabia, and the UAE, given that positive oil supply shocks significantly lead to negative political stability shocks, and negative oil supply shocks significantly lead to positive shocks in political stability.

    Full Text Available The results showed that there was significant difference between husbands’ and their wives' marital satisfaction. Stepwise regression analyses revealed that relational skills and marriage duration were, respectively, significant predictors of husbands’ marital satisfaction. Also, relational skills and some of relational beliefs- such as "things should always be perfect between us", "we should do everything together" and "romanticism", had significant contribution in prediction of wives’ martial satisfaction, respectively. Contributions of other relational beliefs were not significant. These results clarified the role of relational shills and relational beliefs in marital satisfaction, and confirmed that cognitive-behavior approaches, through training relational skills for couples, and therapeutic interventions to change wives' irrational beliefs would be effective in treating marital problems. This Study, according to cognitive-behavior approach, tries to investigate the role of relationship beliefs and relationship skills in couples' marital satisfaction. To do so, 160 persons (80 couples from Tabriz were selected.  After establishing the motivation for participation in the research and getting their informed consent, they were asked to fill out Relationship Beliefs Questionnaire (RBQ, Moradi's marital relationship skills questionnaire and marital satisfaction questionnaire (ENRICH.

    Full Text Available Machiavellianism is characterised by a manipulative interpersonal style, willingness to exploit others, and a preference for emotionally detached relationships. The present studies investigate the extent to which Machiavellianism influences relationship satisfaction and romantic relationship quality. In Study 1, 194 heterosexual partnered women completed Machiavellianism and Relationship Satisfaction measures. Women with higher levels of Machiavellianism reported lower levels of relationship satisfaction. In Study 2, 132 heterosexual partnered women completed Machiavellianism, Trust, Commitment, Control, and Emotional Abuse scales. Women with higher levels of Machiavellianism perceived their partners to be less dependable, reported less faith in their partners, and were less willing to persist with the relationship than those with low levels of Machiavellianism. With regards to negative behavior, Machiavellianism predicted each form of control and emotional abuse investigated, such that those with high levels of Machiavellianism were more likely to engage in controlling behavior and emotional abuse. Findings have important implications for the prediction of romantic relationship quality and in particular for negative behavior such as control and abuse.

    The aim of this study was to investigate the rate of relationship dissatisfaction among Australian women during the first year after childbirth and to uncover factors affecting their relationships. Postnatal women who had given birth during the previous 12 months were invited to participate in a cross-sectional online study. A comprehensive, multisection questionnaire, as well as the Relationship Assessment Scale (RAS), Female Sexual Function Index (FSFI), and Patient Health Questionnaire - 8 (PHQ-8), were used to collect data. Responses were analyzed using SPSS for Windows. Results showed that 37.2% of the participants experienced relationship dissatisfaction. Results of the multiple logistic regression revealed that the following were significant risk factors for relationship dissatisfaction during the first postpartum year: annual income of less than AU$50,000, sexual dysfunction, and a clinical diagnosis of depression and having symptoms of depression according to the PHQ-8 scores (p relationship, women who were in a same-sex relationship were less likely to have relationship dissatisfaction. In addition, in the period six to 12 months postpartum, women were less likely to have relationship dissatisfaction compared to the period 5 months or less postpartum (p < 0.05).

    Full Text Available Television crime dramas and shows are very popular all over the world. This popularity is not bound to a certain age group, rather all the TV viewers like these shows very much. Like other countries, dozens of TV channels are telecasting these crime shows in Pakistan. Furthermore, few of the channels telecast crime shows at prime time which attests the popularity of such genre. Some of the media contents behave in morally disputed ways. The crime depictions as re-enactments of TV crime shows are questionable in the field of research signifying diverse cultural contexts. A large number of people are habitual to watch these shows, which may probably come out with negative behavioural outcomes. Especially the children who are at their behavioural developmental phase; are more susceptible to adopt negative behavioural leanings. In this research effort, introduction and detail of TV crime shows in Pakistan are provided, the literature concerning “media as risk factor“ in children development is discussed, and relevant theories inferences are deliberated.it was found that media has powerful role in behaviour formulating of children and violence media portrayal (TV crime shows may appear with grave concerns. Previous scientific literature was reviewed to find and discuss the problem in hand. In the research effort, the literature review provides research propositions to explore further dimensions to TV crime shows’ effects and possible negative or positive behavioural outcomes in children behaviour.

    People often attempt to shape others' perceptions of them, but the role of romantic relationships in this process is unknown. The present set of studies investigates relationship visibility, the centrality of relationships in the self-images that people convey to others. We propose that attachment underlies relationship visibility and test this hypothesis across three studies in the context of Facebook. Avoidant individuals showed low desire for relationship visibility, whereas anxious individuals reported high desired visibility (Studies 1 and 2); however, similar motives drove both groups' actual relationship visibility (Study 1). Moreover, both avoidant individuals and their partners were less likely to make their relationships visible (Studies 1 and 3). On a daily basis, when people felt more insecure about their partner's feelings, they tended to make their relationships visible (Study 3). These studies highlight the role of relationships in how people portray themselves to others. © 2014 by the Society for Personality and Social Psychology, Inc.

    four selfrepot questionnaires. The childhood attachment was measured by Attachment History Paragraphs (Granqvist & Kirkpatrick, 2004, adult attachment was measured by The Experiences in Close Relationships Questionnaire (Brennan, Clark, & Shaver, 1998 and satisfaction in marriage was measuredby two measures: Quality Marriage Index (Norton, 1983 and Kansas Marital Satisfaction Scale (Schumm, Bollman, & Jurich, 1997.The research sample consisted of 78 heterosexual married couple, together 156 people. The average length of marriages is 20.76 years. Participants were instructed to complete the questionnaires independently. The relations between variables were examined by correlation analysis and cluster analysis. People with a secure attachment style and their partners were most satisfied with their marriages. Our study showed relation between dismissive attachment style and low level of marital satisfaction for the individual, and for the partner of the examined one. The results of our study did not suggest any relationship between childhood attachment and marital satisfaction. The results indicate that secure attachment style is related to higher level of relationship satisfaction, in spite of stressful situation or demanding changes which are occurring in marriage. People with insecure attachment style devote a lot of effort to reinforce marital and couple relationship stability during difficult situations in relationship. Connection between marital satisfaction and childhood attachment has not been proven. The reason may be that childhood attachment is not always totally stable and it can be changed by life experience or personal characteristics of the individual. Our research confirmed that attachment is related to satisfaction in marriage. Research of relationship between attachment and factors affecting marriage is very beneficial, because new finding in this topic can help in clinical practice.

    Full Text Available In this study, the relationship between macroeconomic variables and Istanbul Stock Exchange (ISE industry index is examined. Over the past years, numerous studies have analyzed these relationships and the different results obtained from these studies have motivated further research. The relationship between stock exchange index and macroeconomic variables has been well documented for the developed markets. However, there are few studies regarding the relationship between macroeconomic variables and stock exchange index for the developing markets. Thus, this paper seeks to address the question of whether macroeconomic variables have a significant relationship with ISE industry index using monthly data for the period from 2003 to 2010. The selected macroeconomic variables for the study include interest rates, consumer price index, money supply, exchange rate, gold prices, oil prices, current account deficit and export volume. The Johansen’s cointegration test is utilized to determine the impact of selected macroeconomic variables on ISE industry index. The result of the Johansen’s cointegration shows that macroeconomic variables exhibit a long run equilibrium relationship with the ISE industry index.

    Background and aims Bruxism is defined as a habitual nonfunctional forceful contact between occlusal tooth surfaces. In younger children bruxism may be a consequence of the masticatory neuromuscular system immaturity. The aim of this study was to assess the prevalence of bruxism and investigate the relationship between occlusal factors and bruxism among preschool children. Materials and methods In this cross-sectional survey, 400 3-6-year-old children were selected randomly from different preschools in Isfahan, Iran. The subjects were divided into two groups of bruxers and non-bruxers as determined by the clinical examination and their parents’ reports. The examiner recorded the primary canines (Class I, Class II, and Class III) and molars (mesial step, distal step, flash terminal plane) relationship, existence of anterior and posterior crossbite, open and deep bite. Also, rotated teeth, food impaction, sharp tooth edges, high restorations, extensive tooth caries, and painful teeth (categorized as irritating tooth conditions) were evaluated. The relationship between bruxism and occlusal factors and irritating tooth conditions was evaluated with chi-square test. Results Bruxism was seen in 12.75% of the subjects. Statistically significant relationships existed between bruxism and some occlusal factors, such as flash terminal plane (P = 0.023) and mesial step (P = 0.001) and also, between food impaction, extensive tooth caries, tooth pain, sharp tooth edge and bruxism. Conclusion The results showed significant relationship of bruxism with primary molar relationships and irritating tooth conditions among preschool children. PMID:23277860

    Recent studies suggest that the online and offline behaviors young people display in romantic relationships are closely related. However, the differential effects of the dimensions of couple quality in the online context have not yet been explored in depth. The aim of this study was to explore online couple quality in young-adult relationships, and its association with romantic relationship satisfaction, also looking at effects of gender, age, and length of the relationship. 431 university students currently in a romantic relationship (68.2% females; mean age = 21.57) participated in this study. They completed different self-report measures to tap the online quality of their romantic relationships (online intimacy, control, jealousy, intrusiveness, cyberdating practices, and communication strategies) and level of satisfaction with those relationships. Results showed that participants more often reported online intimacy (M men = 2.49; M women = 2.38) than the negative scales of online quality (mean ranged from .43 to 1.50), and all the online quality scales decreased with age (correlations ranged from -.12 to -.30) and relationship length (correlations ranged from -.02 to -.20). Linear regression analyses indicated that online intimacy (b = .32, p = .001) and intrusiveness (b = .11, p = .035) were positively related to relationship satisfaction, while cyberdating practices (b = -.20, p = .001) and communication strategies (b = -.34, p = .001) were negatively correlated with relationship satisfaction. Moreover, gender and relationship length moderated some of these associations. Results indicate that while online quality and relationship satisfaction are related, the impact of different online quality dimensions on relationship satisfaction differs depending on a participant's sex, age, and relationship length.

  12. Partner Market Opportunities and Relationship Stability

    2015-10-01

    Full Text Available Although partner market opportunities are generally considered to be important for relationship stability, they have never been measured accurately. In order to be able to test the anticipated effects of partner market opportunities, this study conceptualises them as individual opportunities for contact and interaction in concrete social contexts, like the neighbourhood, the workplace, leisure activities, etc. Using data from the German Marriage Market Survey, we first examine the impact of individual partner market opportunities on the risk of separation. Second, we examine to what extend the most frequently studied determinants of divorce and separation depend on partner market opportunities. Our results show that the number of opposite sex contacts increases the probability of separation. Sharing the same contacts with one’s partner decreases the risk of separation. Our results indicate further that reducing opposite sex contacts in the course of the relationship is partly responsible for the higher stability of longer-lasting relationships. Having a migration background is associated with fewer opposite sex contacts. This means that having a migration background would be more destabilising if these individuals did not have less opposite sex contacts than individuals without a migration background. In contrast, joint home ownership, church attendance, higher education and residing in western Germany would generally be more stabilising if these factors were not connected with more opposite sex contacts.

    Personality disorders (PDs) are inherently associated with deficits in relating to other people. Previous research has shown consistent negative associations between categorical PD symptoms and relationship satisfaction. The present studies extend on these findings by examining the role of maladaptive traits in a number of ways. Self- and partner-reported maladaptive traits of both partners are included. Moreover, the present studies add a couple-centered approach by investigating the effects of actual similarity, perceptual similarity, and perceptual accuracy of the maladaptive trait profile on relationship satisfaction. PDs are conceptualized using 2 dimensional maladaptive trait models, that is, the Dimensional Assessment of Personality Pathology-Basic Questionnaire in Study 1 and the Personality Inventory for DSM-5 in Study 2. A total of 167 heterosexual couples participated in Study 1 and 52 heterosexual couples in Study 2. The actor-partner interdependence model was used to examine the associations between traits and relationship satisfaction, whereas the coefficient of profile agreement was used for the couple-centered analyses. Overall, results showed that the presence of maladaptive traits within romantic relationships has a detrimental effect on relationship satisfaction. Self-ratings on maladaptive traits, how we perceive our partners, and how we are perceived by our partners on maladaptive traits make significant contributions to our relationship (dis)satisfaction. Among the maladaptive traits, negative affect and detachment were most consistently negatively associated with relationship satisfaction. The couple-centered perspective showed less explanatory value but nontrivial associations between perceptual similarity and relationship satisfaction were found in Study 2.

  20. Business-Community Relationships for Extractive Industries: A Case Study in Peru

    Directory of Open Access Journals (Sweden)

    Jose Ventura

    2017-07-01

    Full Text Available Natural resource-based economies have long relied on foreign demand to fuel their growth. For instance, the extractive sectors in Peru have experienced a rapid expansion, driven by a rising demand for commodities. Alongside economic growth, extractive operations have triggered social and environmental concerns among the various stakeholders, thus resulting in either social conflict or a deterioration of the relationship between companies in the extractive industries and local communities. In this context, the purpose of this paper is to understand the relationships between companies in the extractive industries and rural families. This research uses the case-study method. The findings show that a trustful relationship is supported by a beneficiary-society approach that builds upon philanthropic and ethical types of relationships. Unlike the type of relationship based on economic or legal interests, a trust-based relationship offers avenues for managing social conflict that have yet to be explored.

    2012-08-01

    Full Text Available The main objective of this study was to investigate the relationship between specific coping strategies and problem-solving/communication behaviors in close relationships. The sample consisted of 72 couples who completed the Dyadic Adjustment Scale and the Marital Coping Questionnaire and who also participated in a filmed 30-minute discussion where they had to solve a relational problem. Observed behaviors were coded using a macroscopic coding system for dyadic interactions. For both men and women, results show significant relationships between coping strategies, marital interaction, and marital adjustment. For women, coping strategies and behavioral dimensions independently accounted for observed fluctuations in marital satisfaction scores. Theoretical implications of these results are discussed.

  4. Improved Recommendations Based on Trust Relationships in Social Networks

    2017-03-01

    Full Text Available In order to alleviate the pressure of information overload and enhance consumer satisfaction, personalization recommendation has become increasingly popular in recent years. As a result, various approaches for recommendation have been proposed in the past few years. However, traditional recommendation methods are still troubled with typical issues such as cold start, sparsity, and low accuracy. To address these problems, this paper proposed an improved recommendation method based on trust relationships in social networks to improve the performance of recommendations. In particular, we define trust relationship afresh and consider several representative factors in the formalization of trust relationships. To verify the proposed approach comprehensively, this paper conducted experiments in three ways. The experimental results show that our proposed approach leads to a substantial increase in prediction accuracy and is very helpful in dealing with cold start and sparsity.

    Full Text Available ABSTRACT Objective Understanding how adolescents signify their affective relationships and situations of conflict/violence within the dating context. Method A qualitative research with an empirical group comprised of adolescents from a state/public school, using focus group techniques and interviews. The analysis was performed through the interpretation of meanings method based on the hermeneutic-dialectical perspective. Results A total of 19 adolescents participated in the study. Two central theme categories emerged: “Meanings of adolescents’ affective relationships” and “From the (deconstruction of symbolic violence to the expression of other forms of violence”. Conclusion The results show that it is possible to understand situations from affective adolescent relationships in which the legitimation of symbolic violence against women is identified. We believe that acting on the origin of violence at the beginning of adolescents’ relationships is the best way to fight or minimize it, aiming for democratizing gender relations and preventing conjugal violence.

  6. Health Information Technology Continues to Show Positive Effect on Medical Outcomes: Systematic Review.

    2018-02-05

    Health information technology (HIT) has been introduced into the health care industry since the 1960s when mainframes assisted with financial transactions, but questions remained about HIT's contribution to medical outcomes. Several systematic reviews since the 1990s have focused on this relationship. This review updates the literature. The purpose of this review was to analyze the current literature for the impact of HIT on medical outcomes. We hypothesized that there is a positive association between the adoption of HIT and medical outcomes. We queried the Cumulative Index of Nursing and Allied Health Literature (CINAHL) and Medical Literature Analysis and Retrieval System Online (MEDLINE) by PubMed databases for peer-reviewed publications in the last 5 years that defined an HIT intervention and an effect on medical outcomes in terms of efficiency or effectiveness. We structured the review from the Primary Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA), and we conducted the review in accordance with the Assessment for Multiple Systematic Reviews (AMSTAR). We narrowed our search from 3636 papers to 37 for final analysis. At least one improved medical outcome as a result of HIT adoption was identified in 81% (25/37) of research studies that met inclusion criteria, thus strongly supporting our hypothesis. No statistical difference in outcomes was identified as a result of HIT in 19% of included studies. Twelve categories of HIT and three categories of outcomes occurred 38 and 65 times, respectively. A strong majority of the literature shows positive effects of HIT on the effectiveness of medical outcomes, which positively supports efforts that prepare for stage 3 of meaningful use. This aligns with previous reviews in other time frames. ©Clemens Scott Kruse, Amanda Beane. Originally published in the Journal of Medical Internet Research (http://www.jmir.org), 05.02.2018.

  7. Independently evolved upper jaw protrusion mechanisms show convergent hydrodynamic function in teleost fishes.

    2012-05-01

    A protrusible upper jaw has independently evolved multiple times within teleosts and has been implicated in the success of two groups in particular: Acanthomorpha and Cypriniformes. We use digital particle image velocimetry (DPIV) to compare suction feeding flow dynamics in a representative of each of these clades: goldfish and bluegill. Using DPIV, we contrast the spatial pattern of flow, the temporal relationship between flow and head kinematics, and the contribution of jaw protrusion to the forces exerted on prey. As expected, the spatial patterns of flow were similar in the two species. However, goldfish were slower to reach maximal kinematic excursions, and were more flexible in the relative timing of jaw protrusion, other jaw movements and suction flows. Goldfish were also able to sustain flow speeds for a prolonged period of time as compared with bluegill, in part because goldfish generate lower peak flow speeds. In both species, jaw protrusion increased the force exerted on the prey. However, slower jaw protrusion in goldfish resulted in less augmentation of suction forces. This difference in force exerted on prey corresponds with differences in trophic niches and feeding behavior of the two species. The bluegill uses powerful suction to capture insect larvae whereas the goldfish uses winnowing to sort through detritus and sediment. The kinethmoid of goldfish may permit jaw protrusion that is independent of lower jaw movement, which could explain the ability of goldfish to decouple suction flows (due to buccal expansion) from upper jaw protrusion. Nevertheless, our results show that jaw protrusion allows both species to augment the force exerted on prey, suggesting that this is a fundamental benefit of jaw protrusion to suction feeders.

Reality shows, as semblances of the passionfor the real that characterized the 20th century, have already assumed theirfictional face and now articulate culture and invention. At this point, their scriptrefers to some aspects of historical realism, as the mise-en-scène of the ordinaryman, the reduced models, and the dynamics of game.

    Culver, Jennifer

    The purpose of this study was to examine the qualities of support, relatedness, and negative interaction within parent-child and teacher-student relationships and their association with cognitive, psychological, and behavioral engagement. Additionally, this study explored the contributions of cognitive and psychological engagement on behavioral engagement. The role of gender, grade, and ethnicity on relationship quality and engagement was also considered. Participants (n=311) were students in grades three through five from a suburban school district in southeastern Michigan. Perceptions of teacher-student relationship quality varied by grade level. In general, younger students reported greater teacher support and relatedness in comparison to older students. Conversely, older students perceived greater conflict within the teacher-student relationship. Student engagement also varied by grade level, with younger students reporting greater engagement than older students. Ethnicity also contributed to variance in student engagement, with African American students reporting significantly more engagement than Caucasian or Multiracial students. Teacher-student relationship quality was a significant predictor of student engagement, even after controlling for student characteristics and parent-child relationship variables. Results of path analysis revealed that cognitive and psychological engagement contributed significantly to behavioral engagement.

    2010-08-01

    With the diffusion of networked technology, personal relationships can be easily formed and maintained online today. Similar to a face-to-face situation, conflict is also seen in these online relationships. Early theories suggested that computer-mediated communication (CMC) tends to increase conflicts because of the lack of social-context cues, and CMC is not rich enough to manage conflict. As CMC has become part of our daily life, we often face conflict online, and thus we need to understand how people manage conflict online. This study explored how online users manage interpersonal conflict. Self-report survey data from 159 university students were analyzed to examine their conflict-management styles in association with the perceived closeness of the online relationship and a future intention toward the relationship. The results indicated that online users select cooperative management styles to handle conflict in their close relationships. In addition, online users avoid less cooperative styles when they want to continue the relationship.

    2016-11-01

    "MythBusters," the long-running though recently discontinued Discovery Channel science entertainment television program, has proven itself to be far more than just a highly rated show. While its focus is on entertainment, the show employs an array of pedagogical techniques to communicate scientific concepts to its audience. These techniques include: achieving active learning, avoiding jargon, employing repetition to ensure comprehension, using captivating demonstrations, cultivating an enthusiastic disposition, and increasing intrinsic motivation to learn. In this content analysis, episodes from the show's 10-year history were examined for these techniques. "MythBusters" represents an untapped source of pedagogical techniques, which science educators may consider availing themselves of in their tireless effort to better reach their students. Physics educators in particular may look to "MythBusters" for inspiration and guidance in how to incorporate these techniques into their own teaching and help their students in the learning process.

The toils and efforts of daily lives have often been broken up by events of all kinds as humans seek an escape from the harsh reality of existence and events provide the outlet. Events are classified into four categories according to Shone and Parry (2010: 5 namely leisure (sport, recreation, personal (weddings, birthdays, cultural (art, folklore and organizational (politics, commercial. Successful events either match or exceed visitor motives and goals. It is critical that data be collected from visitors to determine their motives and goals in order to satisfy them and thereby encouraging repeat visits. One such event is the annual air show held at the Zwartkop Air Force Base (AFB in Pretoria, South Africa. Zwartkop AFB is also home to the South African Air Force (SAAF museum that also the hosts of the air show. Much of the museum‟s funds are generated through hosting the air show and sponsor contributions. Visitor goal satisfaction should therefore be of critically importance to the program planners.

Such hardware often serves as a remembrance of times passed and as a testament to those who perished. For many visiting museums and air shows, curiosity plays a big role. The particular focus of this article will be on how the goal theory of leisure travel can be utilized by the air show organizers to enhance visitor experience to an air show.

    The purpose of the present research is to better understand how relationship autonomy-having more self-determined reasons for being committed to a relationship-contributes to pro-relationship responses to transgressions in romantic relationships (e.g., forgiveness and accommodation). Study 1 employed a cross-sectional design (N = 350) and Study 2 used a weekly diary (N = 121) to test associations between relationship autonomy and pro-relationship responses to transgressions. Studies 3 and 4 utilized dyadic designs (Study 3: N = 200 couples, 400 individuals; Study 4: N = 275 couples, 550 individuals) to determine how both partners' relationship autonomy is associated with pro-relationship responses. Results revealed that relationship autonomy is robustly associated with pro-relationship responses to transgressions, both as general tendencies and as responses to idiosyncratic transgressions. Results of actor-partner interdependence model (APIM) analyses in Studies 3 and 4 provide evidence that one's partner's relationship autonomy is important for promoting pro-relationship responses as well. Study 4 also found that people perceive that partners respond better to transgressions if their partner is high in relationship autonomy. This research provides consistent and compelling evidence that the degree of self-determination underlying commitment is important for understanding how people respond to transgressions in their relationships, beyond their current levels of commitment. © 2017 Wiley Periodicals, Inc.

    One of CERN's new gas-fuelled cars was a special guest at the press days of the Geneva motor show this year. The car enjoyed a prominent position on the Gazmobil stand, right next to the latest Mazeratis and Ferraris. Journalists previewing the motor show could discover CERN's support for green technologies and also find out more about the lab - home to the fastest racetrack on the planet, with protons in the LHC running at 99.9999991% of the speed of light.

    Full Text Available The traditional methods to teach biochemistry in most universities are based on the memorization of chemical structures,  biochemical  pathways  and  reagent  names,  which  is  many  times  dismotivating  for  the  students.  We presently describe an innovative, interactive and alternative method for teaching biochemistry to medical and nutrition undergraduate students, called the Biochemistry Show (BioBio Show.The Biobio show is based on active participation of the students. They are divided in groups and the groups face each other. One group faces another one group at a time, in a game based on true or false questions that involve subjects of applied biochemistry (exercise, obesity, diabetes, cholesterol, free radicals, among others. The questions of the Show are previously elaborated by senior students. The Biobio Show has four phases, the first one is a selection exam, and from the second to the fourth phase, eliminatory confrontations happen. On a confrontation, the first group must select a certain quantity of questions for the opponent to answer.  The group who choses the questions must know how to answer and justify the selected questions. This procedure is repeated on all phases of the show. On the last phase, the questions used are taken from an exam previously performed by the students: either the 9-hour biochemistry exam (Sé et al. A 9-hour biochemistry exam. An iron man competition or a good way of evaluating undergraduate students? SBBq 2005, abstract K-6 or the True-or-False exam (TFE (Sé et al. Are tutor-students capable of writing good biochemistry exams? SBBq 2004, abstract K-18. The winner group receives an extra 0,5 point on the final grade. Over 70% of the students informed on a questionnaire that the Biobio Show is a valuable tool for learning biochemistry.    That is a new way to enrich the discussion of biochemistry in the classroom without the students getting bored.

    This study examined, in a longitudinal design, the contributions of three different relationships, namely marital, parent-child and best friend, to the capacity for intimacy in romantic relationships of Israeli male adolescents, as well as the mediating role of socio-emotional capacities. Eighty-four 17-year-old adolescents and their parents filled out questionnaires concerning the quality of these relational contexts. Four years later the Intimacy Status Interview was administered to the adolescents at the conclusion of their mandatory military service to examine closeness, separateness, and commitment within their romantic relationships. Results showed that all relational contexts were related to capacity for intimacy (directly or indirectly), with higher relational qualities associated with better capability for intimacy. The marital relationship was associated with intimacy through its effect on the parent-child relationships. The effects of the parent-child relationships on the capacity for intimacy were mediated through the adolescents' socio-emotional capabilities. The contribution of the parent-adolescent relationships to the capacity for closeness and commitment was further mediated through relationships with the best friend, whereas the contribution to the capacity for separateness was not. A substantial number of our participants showed high capability for intimacy although in the military service context the circumstances for the development of intimacy were quite limited and non-optimal. Exploration of the separateness and closeness facets of intimacy in romantic relationships in the two sexes and in other contexts is recommended.
