College freshmen face a variety of academic and social challenges as they adjust to college life that can place them at risk for a number of negative outcomes, including depression and alcohol-related problems. Orientation classes that focus on teaching incoming students how to better cope with college-oriented stress may provide an opportunity to prevent the development of these adjustment problems. This article outlines a program based on behavioral activation that can be integrated into college orientation programs to provide a more comprehensive orientation experience. Data are presented from an initial pilot study in which 71 first-semester freshman at the University of Maryland participated in a 15-week, 2 hr per week orientation class (n = 37 in the behavioral activation-enhanced orientation classes and n = 34 in the control orientation as usual classes). Students' depression and alcohol use were evaluated at the beginning, middle, and end of the course. Results indicated a Time × Group interaction such that problem drinking (but not consumption) was significantly reduced across assessments in the behavioral activation classes and largely unchanged in the standard classes. No difference was observed in depression scores; however, fairly low depression scores across the 3 time points may have limited the opportunity to observe any meaningful impact of the orientation classes on depression. The authors conclude with a discussion of the implications of their findings for preventing adjustment problems among incoming college students and future directions.

In order to examine how rumination and social problem solving intensify depression, the present study investigated longitudinal associations among each dimension of rumination and social problem solving and evaluated aspects of these constructs that predicted subsequent depression. A three-wave longitudinal study, with an interval of 4 weeks between waves, was conducted. Japanese university students completed the Beck Depression Inventory-Second Edition, Ruminative Responses Scale, Social Problem-Solving Inventory-Revised Short Version, and Interpersonal Stress Event Scale on three occasions 4 weeks apart ( n  = 284 at Time 1, 198 at Time 2, 165 at Time 3). Linear mixed models were analyzed to test whether each variable predicted subsequent depression, rumination, and each dimension of social problem solving. Rumination and negative problem orientation demonstrated a mutually enhancing relationship. Because these two variables were not associated with interpersonal conflict during the subsequent 4 weeks, rumination and negative problem orientation appear to strengthen each other without environmental change. Rumination and impulsivity/carelessness style were associated with subsequent depressive symptoms, after controlling for the effect of initial depression. Because rumination and impulsivity/carelessness style were not concurrently and longitudinally associated with each other, rumination and impulsive/careless problem solving style appear to be independent processes that serve to intensify depression.

Social anxiety disorder (SAD) in children is often comorbid with generalized anxiety disorder (GAD). We investigated whether worry, intolerance of uncertainty, beliefs about worry, negative problem orientation and cognitive avoidance, that are typically associated with GAD, are present in children with SAD. Participants included 60 children (8-12 years), matched on age and gender. Groups included children: with primary GAD and without SAD (GAD); with primary SAD and without GAD (SAD); and without an anxiety disorder (NAD). GAD and SAD groups scored significantly higher than the NAD group on worry, intolerance of uncertainty, negative beliefs about worry and negative problem orientation, however, they did not score differently from each other. Only the GAD group scored significantly higher than the NAD group on cognitive avoidance. These findings further understanding of the structure of SAD and suggest that the high comorbidity between SAD and GAD may be due to similar underlying processes within the disorders.

Intercollegiate athletes report greater alcohol consumption and more alcohol-related problems than their non-athlete peers. Although college athletes share many of the same problems faced by non-athletes, there are some consequences that are unique to athletes. Studies have demonstrated that alcohol negatively affects athletic performance including increased dehydration, impeded muscle recovery, and increased risk for injury. Beyond risk factors for alcohol misuse that may affect college students in general, research has begun to examine risk factors that are unique to collegiate athletes. For example, research has found that off-season status, the leadership role, and athlete-specific drinking motives are associated with increased alcohol use. Given these findings, it is possible that other athlete-specific variables influence alcohol misuse. One such variable may be sport achievement orientation. The purpose of the current study was to examine the relationship between sport achievement orientation and alcohol outcomes. Given previous research regarding seasonal status and gender, these variables were examined as moderators. Varsity athletes (n=263) completed the Sport Orientation Questionnaire, which assesses sport-related achievement orientation on three scales (Competitiveness, Win Orientation, and Goal Orientation). In addition, participants completed measures of alcohol use and alcohol-related problems. Results indicated that Competitiveness, Win Orientation, and Goal Orientation were all significantly associated with alcohol use, but not alcohol-related problems. Moreover, these relationships were moderated by seasonal status and gender. These interactions, clinical implications, and limitations are discussed. © 2013.

In this study, bullying is examined in light of the “prosocial security hypothesis”— i.e., the hypothesis that insecure attachment, with temperamental dispositions such as sensation seeking, may foster individualistic, competitive value orientations and problem behaviors. A group of 375 Italian students (53% female; Mean age = 12.58, SD = 1.08) completed anonymous questionnaires regarding attachment security, social values, sensation seeking, and bullying behaviors. Path analysis showed that attachment to mother was negatively associated with bullying of others, both directly and through the mediating role of conservative socially oriented values, while attachment to father was directly associated with victimization. Sensation seeking predicted bullying of others and victimization both directly and through the mediating role of conservative socially oriented values. Adolescents’ gender affected how attachment moderated the relationship between sensation seeking and problem behavior. PMID:29535668

Rejection Sensitivity and Depression: Indirect Effects Through Problem Solving.

PubMed

Kraines, Morganne A; Wells, Tony T

2017-01-01

Rejection sensitivity (RS) and deficits in social problem solving are risk factors for depression. Despite their relationship to depression and the potential connection between them, no studies have examined RS and social problem solving together in the context of depression. As such, we examined RS, five facets of social problem solving, and symptoms of depression in a young adult sample. A total of 180 participants completed measures of RS, social problem solving, and depressive symptoms. We used bootstrapping to examine the indirect effect of RS on depressive symptoms through problem solving. RS was positively associated with depressive symptoms. A negative problem orientation, impulsive/careless style, and avoidance style of social problem solving were positively associated with depressive symptoms, and a positive problem orientation was negatively associated with depressive symptoms. RS demonstrated an indirect effect on depressive symptoms through two social problem-solving facets: the tendency to view problems as threats to one's well-being and an avoidance problem-solving style characterized by procrastination, passivity, or overdependence on others. These results are consistent with prior research that found a positive association between RS and depression symptoms, but this is the first study to implicate specific problem-solving deficits in the relationship between RS and depression. Our results suggest that depressive symptoms in high RS individuals may result from viewing problems as threats and taking an avoidant, rather than proactive, approach to dealing with problems. These findings may have implications for problem-solving interventions for rejection sensitive individuals.

Performativity Double Standards and the Sexual Orientation Climate at a Southern Liberal Arts University.

This study employs quantitative and qualitative methods to examine how heterosexual, bisexual, and gay students rate and describe a Southern, religiously affiliated university's sexual orientation climate. Using qualitative data, queer theory, and the concept tyranny of sexualized spaces, we explain why non-heterosexual students have more negative perceptions of the university climate than heterosexual male students, in both bivariate and multivariate analyses. Although heterosexual students see few problems with the campus sexual orientation climate, bisexual men and women describe being challenged on the authenticity of their orientation, and lesbian and, to a greater extent, gay male students report harassment and exclusion in a number of settings. These distinct processes are influenced by broader heteronormative standards. We also shed much-needed light on how gendered sexual performativity double standards within an important campus microclimate (fraternity parties) contribute to creating a tyrannical sexualized space and negatively affect overall campus climate perceptions.

Psoriasis is a chronic dermatosis which may cause significant impairment of the patient's quality of life. The purpose of this study was to investigate the social problem-solving skills, perceived stress, negative life events, depression and life satisfaction in psoriasis patients. Data were gathered by means of questionnaires and clinical evaluations from 51 psoriatic patients and 51 matched healthy controls. Average disease duration was 16.47 years and average Psoriasis Area and Severity Index score was 3.67. Compared with the controls, the patients displayed lower social problem-solving skills. They displayed higher negative problem orientation and impulsive-careless problem-solving style scores than the controls. Patients tended also to show more avoidant problem-solving style and lower life satisfaction than controls. There was no difference between psoriatic patients and controls in terms of depression, perceived stress and negative life events. Higher social problem-solving skills were associated with lower depression, perceived stress and fewer numbers of negative life events but higher level of life satisfaction. The patient group largely included mild and moderate psoriatic cases. The findings of the study suggest that problem-solving training or therapy may be a suitable option for alleviating levels of psychological distress in patients suffering from psoriasis. © 2014 European Academy of Dermatology and Venereology.

Public attitudes toward child undervaccination: A randomized experiment on evaluations, stigmatizing orientations, and support for policies.

Carpiano, Richard M; Fitz, Nicholas S

Child undervaccination is a complex public health problem and a contentious social and political issue. Efforts to increase vaccination coverage require understanding how the public evaluates different reasons for child undervaccination, which may influence attitudes, stigmatizing behaviors, and support for vaccination policies. We conducted a vignette experiment with a United States national online sample (n = 1469) to investigate how and why different undervaccination actions shape evaluations (blame, anger, sympathy, differentness, credibility, dangerousness), stigmatizing orientations (social distance, discrimination), and support for particular policies (e.g., research funding, belief exemptions, fines). Each participant was randomly assigned to read one of four vignettes that described a mother who either refused vaccines, delayed vaccines, encountered social barriers to obtaining vaccines, or was up-to-date on vaccines for her child. Compared to the up-to-date condition, each undervaccination action predicted significantly more negative evaluations and stigmatizing orientations. Vaccine refusal was the most negatively appraised. Differences in social distance and discrimination were explained by negative evaluations about the parent. These evaluations and orientations predicted support for a range of policies. Negative parental evaluations were associated with increased support for more severe policies. We discuss the implications of these findings for addressing undervaccination and informing health scholarship on stigma. Copyright © 2017 Elsevier Ltd. All rights reserved.

The Role of Sexual Orientation in the Victimization and Recovery of Sexual Assault Survivors.

2015-01-01

Few studies examine the sexual violence victimization and recovery of nonheterosexuals. Limited available research suggests that lesbian and bisexual women are at increased risk for sexual violence and experience more recovery problems following assault than heterosexuals. We examine differences by sexual orientation in victimization, recovery, and social reactions as well as whether racial differences relate to recovery in female sexual assault survivors (N = 1,863) from the community. Bisexual women emerged as a distinct group from heterosexual women with greater recovery problems and experienced greater impact of social reactions. Black sexual minority women also had more negative outcomes than White sexual minority women. Results suggest that differences in sexual orientation and race relate to poorer recovery, especially for survivors with multiple marginalized identities.

Disclosing sexual orientation to parents is a challenging developmental task for lesbian and gay adolescents. The aim of the study is to investigate parental negative reaction to coming out, which is associated with high levels of internalized sexual stigma and psychological problems. Participants' perceptions of their parents' reactions, age at coming out, gender, parental political orientation and religiosity, family functioning, and internalized sexual stigma were assessed in 150 Italian homosexual adolescents. Findings confirm that negative parental reactions are connected to poor family functioning and strong beliefs in traditional values. Path analysis results identified that negative reaction to coming out mediates the effect between a more rigid family functioning and internalized sexual stigma. Implications for clinical and social fields are discussed. © The Author(s) 2014.

Mental Health and School Functioning for Girls in the Child Welfare System: the Mediating Role of Future Orientation and School Engagement.

2017-01-01

This study investigated the association between mental health problems and academic and behavioral school functioning for adolescent girls in the child welfare system and determined whether school engagement and future orientation meditated the relationship. Participants were 231 girls aged between 12 and 19 who had been involved with the child welfare system. Results indicated that 39% of girls reported depressive symptoms in the clinical range and 54% reported posttraumatic symptoms in the clinical range. The most common school functioning problems reported were failing a class (41%) and physical fights with other students (35%). Participants reported a mean number of 1.7 school functioning problems. Higher levels of depression and PTSD were significantly associated with more school functioning problems. School engagement fully mediated the relationship between depression and school functioning and between PTSD and school functioning, both models controlling for age, race, and placement stability. Future orientation was not significantly associated with school functioning problems at the bivariate level. Findings suggest that school engagement is a potentially modifiable target for interventions aiming to ameliorate the negative influence of mental health problems on school functioning for adolescent girls with histories of abuse or neglect.

2008-04-01

Between 1989 and 2005, Israel absorbed over a million new immigrants, about 90% of whom were from the Former Soviet Union (FSU). The present study investigated the adaptation of these FSU new immigrants in a sample of 301 participants (67% women, ages 25-45 years), who completed inventories measuring personal resources (tolerance of ambiguity and cognitive flexibility), cognitive appraisals (of employment, language, and housing problems), coping strategies, well-being, distress, and willingness to remain in Israel. A structural equation modeling (SEM) analysis showed that tolerance for ambiguity and cognitive flexibility contributed positively to control appraisals, task-oriented coping, and level of participant well-being, and negatively to threat/loss appraisals, emotion/avoidance-oriented coping, and distress. Control appraisals contributed to task-oriented coping, whereas threat/loss appraisals contributed to both emotion/avoidance-oriented and task-oriented coping. Control and challenge appraisals, and task-oriented coping, contributed positively to participant willingness to remain in Israel, whereas emotion/avoidance-oriented coping contributed positively to distress levels, which in turn were negatively related to willingness to remain in Israel. The results of this study have significant implications for such aspects of immigrant adaptation as absorption policies and the provision of individual care by professionals and organizations.

Multidimensional Sexual Perfectionism and Female Sexual Function: A Longitudinal Investigation.

PubMed

Stoeber, Joachim; Harvey, Laura N

2016-11-01

Research on multidimensional sexual perfectionism differentiates four forms: self-oriented, partner-oriented, partner-prescribed, and socially prescribed. Self-oriented sexual perfectionism reflects perfectionistic standards people apply to themselves as sexual partners; partner-oriented sexual perfectionism reflects perfectionistic standards people apply to their sexual partner; partner-prescribed sexual perfectionism reflects people's beliefs that their sexual partner imposes perfectionistic standards on them; and socially prescribed sexual perfectionism reflects people's beliefs that society imposes such standards on them. Previous studies found partner-prescribed and socially prescribed sexual perfectionism to be maladaptive forms of sexual perfectionism associated with a negative sexual self-concept and problematic sexual behaviors, but only examined cross-sectional relationships. The present article presents the first longitudinal study examining whether multidimensional sexual perfectionism predicts changes in sexual self-concept and sexual function over time. A total of 366 women aged 17-69 years completed measures of multidimensional sexual perfectionism, sexual esteem, sexual anxiety, sexual problem self-blame, and sexual function (cross-sectional data). Three to six months later, 164 of the women completed the same measures again (longitudinal data). Across analyses, partner-prescribed sexual perfectionism emerged as the most maladaptive form of sexual perfectionism. In the cross-sectional data, partner-prescribed sexual perfectionism showed positive relationships with sexual anxiety, sexual problem self-blame, and intercourse pain, and negative relationships with sexual esteem, desire, arousal, lubrication, and orgasmic function. In the longitudinal data, partner-prescribed sexual perfectionism predicted increases in sexual anxiety and decreases in sexual esteem, arousal, and lubrication over time. The findings suggest that partner-prescribed sexual perfectionism contributes to women's negative sexual self-concept and female sexual dysfunction.

To investigate whether patients with high and low depression scores after stroke use different coping strategies and problem-solving skills and whether these variables are related to psychosocial health-related quality of life (HRQOL) independent of depression. Cross-sectional study. Two rehabilitation centers. Patients participating in outpatient stroke rehabilitation (N=166; mean age, 53.06±10.19y; 53% men; median time poststroke, 7.29mo). Not applicable. Coping strategy was measured using the Coping Inventory for Stressful Situations; problem-solving skills were measured using the Social Problem Solving Inventory-Revised: Short Form; depression was assessed using the Center for Epidemiologic Studies Depression Scale; and HRQOL was measured using the five-level EuroQol five-dimensional questionnaire and the Stroke-Specific Quality of Life Scale. Independent samples t tests and multivariable regression analyses, adjusted for patient characteristics, were performed. Compared with patients with low depression scores, patients with high depression scores used less positive problem orientation (P=.002) and emotion-oriented coping (P<.001) and more negative problem orientation (P<.001) and avoidance style (P<.001). Depression score was related to all domains of both general HRQOL (visual analog scale: β=-.679; P<.001; utility: β=-.009; P<.001) and stroke-specific HRQOL (physical HRQOL: β=-.020; P=.001; psychosocial HRQOL: β=-.054, P<.001; total HRQOL: β=-.037; P<.001). Positive problem orientation was independently related to psychosocial HRQOL (β=.086; P=.018) and total HRQOL (β=.058; P=.031). Patients with high depression scores use different coping strategies and problem-solving skills than do patients with low depression scores. Independent of depression, positive problem-solving skills appear to be most significantly related to better HRQOL. Copyright © 2015 American Congress of Rehabilitation Medicine.

2016-01-01

Background Doping is a highly relevant problem in sport, even in adolescent athletes. Knowledge of the psychological factors that influence doping susceptibility in young elite athletes remains sparse. Objectives This study investigated the predictive potential of different health-psychological constructs and well-being on doping susceptibility. The main hypotheses to be tested were positive associations of fear of failure, external locus of control, and ego-oriented goal orientation as well as negative associations of confidence of success, task orientation, internal locus of control, and performance motivation with doping susceptibility. Low levels of well-being are furthermore expected to be associated with doping susceptibility. Methods Within this cross-sectional study, 1,265 Austrian junior athletes aged between 14 and 19 years responded to a paper-pencil questionnaire. Results Performance motivation was a negative, while depressive mood, self-esteem, fear of failure and ego-oriented goal orientation were positive predictors of doping susceptibility. In addition, participants who were offered performance enhancing substances in the past were particularly susceptible to doping. Conclusions The study corroborates the predictive value of classical psychological constructs in doping research, initially analyzed in view of adult athletes, also for adolescents’ doping susceptibility.

The present study aimed to investigate the relations among perceived parental psychological control (PPC), autonomy and relatedness, and negative outcomes during emerging adulthood in two cultural contexts: Italy and the USA. More specifically, we explored the mechanisms through which dependency-oriented PPC (DPPC) and achievement-oriented PPC (APPC) are associated with both internalizing and externalizing difficulties, focusing on the mediating role of autonomy and relatedness. Participants were 418 European-American and 359 Italian college students. Results indicated that the expressions of PPC with regard to dependency and achievement were related to emerging adults' negative outcomes through different pathways, and these effects were moderated by the cultural group. The implications of the findings for future related empirical investigations and clinical interventions were discussed.

Justice orientation as a moderator of the framing effect on procedural justice perception.

Sasaki, Hiroyuki; Hayashi, Yoichiro

2014-01-01

Justice orientation is a justice-relevant personality trait, which is referred to as the tendency to attend to fairness issues and to internalize justice as a moral virtue. This study examined the moderating role of justice orientation in the relationship between justice perception and response to a decision problem. The authors manipulated procedural justice and the outcome valence of the decision frame within a vignette, and measured justice orientation of 174 Japanese participants. As hypothesized, the results indicated an interaction between procedural justice and framing manipulation, which was moderated by individual differences in justice orientation. In negative framing, justice effects were larger for individuals with high rather than low justice orientation. The results are explained from a social justice perspective, and the contributions and limitations of this study are also discussed with respect to our sample and framing manipulation.

Undifferentiated Gender Role Orientation, Drinking Motives, and Increased Alcohol Use in Men and Women.

PubMed

Fugitt, Jessica L; Ham, Lindsay S; Bridges, Ana J

2017-05-12

Alcohol misuse has historically affected men more than women. However, the differences in drinking behaviors across sex have steadily decreased over time and accumulating research suggests that gender role orientation, or culturally scripted gender-specific characteristics, and negative reinforcement drinking motives may better explain risk for alcohol use and related problems than sex. The current study tested a mediational model of the undifferentiated orientation (low masculinity and low femininity), an oft neglected orientation despite evidence that it could carry much weight in drinking behaviors, versus the other three gender role orientations, coping and conformity drinking motives, and hazardous alcohol use. Participants were 426 current drinkers over age 21 (41% men; 77.8% Caucasian; M age = 34.5, range = 21-73) residing across the United States who completed an online survey. Structural equation modeling analyses suggested that individuals with an undifferentiated orientation (n = 99), compared to masculine (high masculinity, low femininity; n = 102), feminine (high femininity, low masculinity; n = 113), or androgynous (high masculinity, high femininity; n = 112) orientations, reported higher coping drinking motives, which were positively associated with levels of hazardous alcohol use. Although analyses suggested that undifferentiated individuals reported drinking for conformity motives more often than masculine and androgynous individuals, conformity motives were not associated with increased use. Conclusions/Importance: An undifferentiated gender role orientation may contribute a unique risk for alcohol use and related problems by increasing frequency of drinking to cope, a motive specifically associated with hazardous use trajectories.

Preventing childhood obesity: a solution-oriented research paradigm.

PubMed

Robinson, Thomas N; Sirard, John R

2005-02-01

Past research has identified social and environmental causes and correlates of behaviors thought to be associated with obesity and weight gain among children and adolescents. Much less research has documented the efficacy of interventions designed to manipulate those presumed causes and correlates. These latter efforts have been inhibited by the predominant biomedical and social science problem-oriented research paradigm, emphasizing reductionist approaches to understanding etiologic mechanisms of diseases and risk factors. The implications of this problem-oriented approach are responsible for leaving many of the most important applied research questions unanswered, and for slowing efforts to prevent obesity and improve individual and population health. An alternative, and complementary, solution-oriented research paradigm is proposed, emphasizing experimental research to identify the causes of improved health. This subtle conceptual shift has significant implications for phrasing research questions, generating hypotheses, designing research studies, and making research results more relevant to policy and practice. The solution-oriented research paradigm encourages research with more immediate relevance to human health and a shortened cycle of discovery from the laboratory to the patient and population. Finally, a "litmus test" for evaluating research studies is proposed, to maximize the efficiency of the research enterprise and contributions to the promotion of health and the prevention and treatment of disease. A research study should only be performed if (1) you know what you will conclude from each possible result (whether positive, negative, or null); and (2) the result may change how you would intervene to address a clinical, policy, or public health problem.

'Health should not have to be a problem': talking health and accountability in an internet forum on veganism.

PubMed

Sneijder, Petra; te Molder, Hedwig F M

2004-07-01

This article draws upon insights from discursive psychology to examine how participants in an Internet forum on veganism orient to the relationship between food choice, health and accountability. First, we explore the ways in which participants ascribe responsibility for health problems like vitamin deficiency to individual recipients. By suggesting individual practices as a cause for problems, speakers undermine the notion that problems arise through veganism as a matter of principle. Second, we show how participants construct solutions to individual health problems as involving mundane and simple actions.

Interventions for people suffering from borderline personality disorder (BPD), such as dialectical behaviour therapy, often include a problem-solving component. However, there is an absence of published studies examining the problem-solving abilities of this client group. In this study, the social problem-solving (SPS) abilities of three groups of participants were assessed: a BPD group (n=25), a clinical control (CC) group (n=25) procedure and a non-clinical control (NCC) group (n=25). SPS ability was assessed using the means-end problem-solving (MEPS) procedure and the Social Problem-Solving Inventory-Revised (SPSI-R). The BPD group exhibited deficits in their SPS abilities, however the majority of these deficits were not specific to the BPD group but were also found in the CC group, indicating that a common factor between these two groups, such as negative affect, may account for these observed deficits. Specific SPS deficits were identified in the BPD group: they provided less specific solutions on the MEPS and reported higher levels of negative problem orientation and a more impulsive/carelessness style towards solving social problems. The results of this study provide empirical support for the use of problem-solving interventions with people suffering from BPD.

Future orientation and competence to stand trial: the fragility of competence.

The current study examined the direct, indirect, and interactive effects of age, intellectual ability, psychiatric symptomatology, and future orientation on juvenile adjudicative competence utilizing a secondary sample of 927 youth from the MacArthur Juvenile Adjudicative Competence Study. Consistent with previous research, age, intellectual ability, and future orientation were found to be positively associated with competence, and psychiatric symptomatology was weakly negatively related to competence. Tests of indirect effects revealed that the development of an orientation toward future consequences partially explains the relationship between age and the capacity to reason about legal decision-making. Further, tests of invariance revealed that the competence of immature adolescents is particularly "fragile," in that smaller deficits in cognitive abilities appear to pose greater problems in youths regarding their adjudicative competence than in their more mature peers. Findings are discussed in regard to forensic practice as well as for future research.

Spin reorientation of a nonsymmetric body with energy dissipation

NASA Technical Reports Server (NTRS)

Cenker, R. J.

1973-01-01

Stable rotating semi-rigid bodies were demonstrated analytically, and verified in flights such as Explorer 1 and ATS-5 satellites. The problem arises from the two potential orientations which the final spin vector can take after large angle reorientation from minor to major axis, i.e., along the positive or negative axis of the maximum inertia. Reorientation of a satellite initially spinning about the minor axis using an energy dissipation device may require that the final spin orientation be controlled. Examples of possible applications are the Apogee Motor Assembly with Paired Satellites (AMAPS) configuration, where proper orientation of the thruster is required; and reorientation of ATS-5, where the spin sensitive nature of the despin device (yo-yo mechanism) requires that the final spin vector point is a specified direction.

To describe social problem solving in Chinese baccalaureate nursing students. A descriptive cross-sectional study was conducted with a cluster sample of 681 Chinese baccalaureate nursing students. The Chinese version of the Social Problem-Solving scale was used. Descriptive analyses, independent t-test and one-way analysis of variance were applied to analyze the data. The final year nursing students presented the highest scores of positive social problem-solving skills. Students with experiences of self-directed and problem-based learning presented significantly higher scores in Positive Problem Orientation subscale. The group with Critical thinking training experience, however, displayed higher negative problem solving scores compared with nonexperience group. Social problem solving abilities varied based upon teaching-learning strategies. Self-directed and problem-based learning may be recommended as effective way to improve social problem-solving ability. © 2016 Chinese Cochrane Center, West China Hospital of Sichuan University and John Wiley & Sons Australia, Ltd.

Influence of gender role orientation (masculinity versus femininity) on body satisfaction and eating attitudes in homosexuals, heterosexuals and transsexuals.

The primary aim of this study was to investigate the relationship between gender role orientation and eating disorder attitudes and behaviors and body dissatisfaction in a sample of homosexuals, heterosexuals, and transsexuals. We screened 132 homosexuals, 178 heterosexuals (both male and female), and 15 MtF transsexuals by means of an ad hoc socio-demographic schedule; the Eating Disorders Inventory-2 and Symptom Checklist; the Body Uneasiness Test and the Bem Sex Role Inventory. Differences between homosexual, heterosexual, and transsexual participants emerged, but those data seem to be best explained by the constructs of femininity and masculinity than by the biological gender. The empirical evidence of a positive correlation between femininity and eating problems, and the negative correlation between masculinity and eating problems, is full of implications. Eating disorders appear to be diseases of femininity; masculinity seems to be a protective factor, independently by the biological gender.

Toward Sustainable Anticipatory Governance: Analyzing and Assessing Nanotechnology Innovation Processes

NASA Astrophysics Data System (ADS)

Foley, Rider Williams

Cities around the globe struggle with socio-economic disparities, resource inefficiency, environmental contamination, and quality-of-life challenges. Technological innovation, as one prominent approach to problem solving, promises to address these challenges; yet, introducing new technologies, such as nanotechnology, into society and cities has often resulted in negative consequences. Recent research has conceptually linked anticipatory governance and sustainability science: to understand the role of technology in complex problems our societies face; to anticipate negative consequences of technological innovation; and to promote long-term oriented and responsible governance of technologies. This dissertation advances this link conceptually and empirically, focusing on nanotechnology and urban sustainability challenges. The guiding question for this dissertation research is: How can nanotechnology be innovated and governed in responsible ways and with sustainable outcomes? The dissertation: analyzes the nanotechnology innovation process from an actor- and activities-oriented perspective (Chapter 2); assesses this innovation process from a comprehensive perspective on sustainable governance (Chapter 3); constructs a small set of future scenarios to consider future implications of different nanotechnology governance models (Chapter 4); and appraises the amenability of sustainability problems to nanotechnological interventions (Chapter 5). The four studies are based on data collected through literature review, document analysis, participant observation, interviews, workshops, and walking audits, as part of process analysis, scenario construction, and technology assessment. Research was conducted in collaboration with representatives from industry, government agencies, and civic organizations. The empirical parts of the four studies focus on Metropolitan Phoenix. Findings suggest that: predefined mandates and economic goals dominate the nanotechnology innovation process; normative responsibilities identified by risk governance, sustainability-oriented governance, and anticipatory governance are infrequently considered in the nanotechnology innovation process; different governance models will have major impacts on the role and effects of nanotechnology in cities in the future; and nanotechnologies, currently, do not effectively address the root causes of urban sustainability challenges and require complementary solution approaches. This dissertation contributes to the concepts of anticipatory governance and sustainability science on how to constructively guide nanotechnological innovation in order to harvest its positive potential and safeguard against negative consequences.

Problems and Limitations of Satellite Image Orientation for Determination of Height Models

NASA Astrophysics Data System (ADS)

Jacobsen, K.

2017-05-01

The usual satellite image orientation is based on bias corrected rational polynomial coefficients (RPC). The RPC are describing the direct sensor orientation of the satellite images. The locations of the projection centres today are without problems, but an accuracy limit is caused by the attitudes. Very high resolution satellites today are very agile, able to change the pointed area over 200km within 10 to 11 seconds. The corresponding fast attitude acceleration of the satellite may cause a jitter which cannot be expressed by the third order RPC, even if it is recorded by the gyros. Only a correction of the image geometry may help, but usually this will not be done. The first indication of jitter problems is shown by systematic errors of the y-parallaxes (py) for the intersection of corresponding points during the computation of ground coordinates. These y-parallaxes have a limited influence to the ground coordinates, but similar problems can be expected for the x-parallaxes, determining directly the object height. Systematic y-parallaxes are shown for Ziyuan-3 (ZY3), WorldView-2 (WV2), Pleiades, Cartosat-1, IKONOS and GeoEye. Some of them have clear jitter effects. In addition linear trends of py can be seen. Linear trends in py and tilts in of computed height models may be caused by limited accuracy of the attitude registration, but also by bias correction with affinity transformation. The bias correction is based on ground control points (GCPs). The accuracy of the GCPs usually does not cause some limitations but the identification of the GCPs in the images may be difficult. With 2-dimensional bias corrected RPC-orientation by affinity transformation tilts of the generated height models may be caused, but due to large affine image deformations some satellites, as Cartosat-1, have to be handled with bias correction by affinity transformation. Instead of a 2-dimensional RPC-orientation also a 3-dimensional orientation is possible, respecting the object height more as by 2-dimensional orientation. The 3-dimensional orientation showed advantages for orientation based on a limited number of GCPs, but in case of poor GCP distribution it may cause also negative effects. For some of the used satellites the bias correction by affinity transformation showed advantages, but for some other the bias correction by shift was leading to a better levelling of the generated height models, even if the root mean square (RMS) differences at the GCPs were larger as for bias correction by affinity transformation. The generated height models can be analyzed and corrected with reference height models. For the used data sets accurate reference height models are available, but an analysis and correction with the free of charge available SRTM digital surface model (DSM) or ALOS World 3D (AW3D30) is also possible and leads to similar results. The comparison of the generated height models with the reference DSM shows some height undulations, but the major accuracy influence is caused by tilts of the height models. Some height model undulations reach up to 50 % of the ground sampling distance (GSD), this is not negligible but it cannot be seen not so much at the standard deviations of the height. In any case an improvement of the generated height models is possible with reference height models. If such corrections are applied it compensates possible negative effects of the type of bias correction or 2-dimensional orientations against 3-dimensional handling.

Team safety and innovation by learning from errors in long-term care settings.

Team safety and team innovation are underexplored in the context of long-term care. Understanding the issues requires attention to how teams cope with error. Team managers could have an important role in developing a team's error orientation and managing team membership instabilities. The aim of this study was to examine the impact of team member stability, team coaching, and a team's error orientation on team safety and innovation. A cross-sectional survey method was employed within 2 long-term care organizations. Team members and team managers received a survey that measured safety and innovation. Team members assessed member stability, team coaching, and team error orientation (i.e., problem-solving and blaming approach). The final sample included 933 respondents from 152 teams. Stable teams and teams with managers who take on the role of coach are more likely to adopt a problem-solving approach and less likely to adopt a blaming approach toward errors. Both error orientations are related to team member ratings of safety and innovation, but only the blaming approach is (negatively) related to manager ratings of innovation. Differences between members' and managers' ratings of safety are greater in teams with relatively high scores for the blaming approach and relatively low scores for the problem-solving approach. Team coaching was found to be positively related to innovation, especially in unstable teams. Long-term care organizations that wish to enhance team safety and innovation should encourage a problem-solving approach and discourage a blaming approach. Team managers can play a crucial role in this by coaching team members to see errors as sources of learning and improvement and ensuring that individuals will not be blamed for errors.

The spiral of distrust: (Non-)cooperation in a repeated trust game is predicted by anger and individual differences in negative reciprocity orientation.

Harth, Nicole S; Regner, Tobias

2017-12-01

This study investigated state anger and individual differences in negative reciprocity orientation as predictors of individuals' willingness to cooperate with strangers. In order to observe real behaviour, we used a trust game that was played over six periods. In the trust game, a first player (sender) determines how much of a certain endowment she/he wants to share with a second player (trustee), who then can give something back. We varied whether participants received feedback [feedback (yes, no)] about the trustee's behavioural decision (amount sent back). Supporting our hypotheses, the results suggest that feedback compared with no feedback about the trustee's behaviour increased anger. Specifically, information about low back transfers triggered anger and non-cooperation in return. Importantly, participants with a strong negative reciprocity orientation reported higher levels of anger and were less willing to cooperate with the trustee compared with those with low negative reciprocity orientation. Moreover, even when anger was low, individuals with a strong negative reciprocity orientation were less willing to cooperate compared with those with a low negative reciprocity orientation. Thus, negative reciprocity orientation seems to arouse a spiral of distrust. Theoretical and practical implications of these findings are discussed. © 2016 International Union of Psychological Science.

Primary Objective Social problem solving deficits characterize individuals with traumatic brain injury (TBI). Poor social problem solving interferes with daily functioning and productive lifestyles. Therefore, it is of vital importance to use the appropriate instrument to identify deficits in social problem solving for individuals with TBI. This study investigates factor structure and item-level psychometrics of the Social Problem Solving Inventory-Revised Short Form (SPSI-R:S), for adults with moderate and severe TBI. Research Design Secondary analysis of 90 adults with moderate and severe TBI who completed the SPSI-R:S. Methods and Procedures An exploratory factor analysis (EFA), principal components analysis (PCA) and Rasch analysis examined the factor structure and item-level psychometrics of the SPSI-R:S. Main Outcomes and Results The EFA showed three dominant factors, with positively worded items represented as the most definite factor. The other two factors are negative problem solving orientation and skills; and negative problem solving emotion. Rasch analyses confirmed the three factors are each unidimensional constructs. Conclusions The total score interpretability of the SPSI-R:S may be challenging due to the multidimensional structure of the total measure. Instead, we propose using three separate SPSI-R:S subscores to measure social problem solving for the TBI population. PMID:26052731

Vision-based mobile robot navigation is a vibrant area of research with numerous algorithms having been developed, the vast majority of which either belong to the scene-oriented simultaneous localization and mapping (SLAM) or fall into the category of robot-oriented lane-detection/trajectory tracking. These methods suffer from high computational cost and require stringent labelling and calibration efforts. To address these challenges, this paper proposes a lightweight robot navigation framework based purely on uncalibrated spherical images. To simplify the orientation estimation, path prediction and improve computational efficiency, the navigation problem is decomposed into a series of classification tasks. To mitigate the adverse effects of insufficient negative samples in the “navigation via classification” task, we introduce the spherical camera for scene capturing, which enables 360° fisheye panorama as training samples and generation of sufficient positive and negative heading directions. The classification is implemented as an end-to-end Convolutional Neural Network (CNN), trained on our proposed Spherical-Navi image dataset, whose category labels can be efficiently collected. This CNN is capable of predicting potential path directions with high confidence levels based on a single, uncalibrated spherical image. Experimental results demonstrate that the proposed framework outperforms competing ones in realistic applications. PMID:28604624

To describe and analyze the pharmaceutical orientation given at hospital discharge of transplant patients. This was a cross-sectional, descriptive and retrospective study that used records of orientation given by the clinical pharmacist in the inpatients unit of the Kidney and Liver Transplant Department, at Hospital Universitário Walter Cantídio, in the city of Fortaleza (CE), Brazil, from January to July, 2014. The following variables recorded at the Clinical Pharmacy Database were analyzed according to their significance and clinical outcomes: pharmaceutical orientation at hospital discharge, drug-related problems and negative outcomes associated with medication, and pharmaceutical interventions performed. The first post-transplant hospital discharge involved the entire multidisciplinary team and the pharmacist was responsible for orienting about drug therapy. The mean hospital discharges/month with pharmaceutical orientation during the study period was 10.6±1.3, totaling 74 orientations. The prescribed drug therapy had a mean of 9.1±2.7 medications per patient. Fifty-nine drug-related problems were identified, in which 67.8% were related to non-prescription of medication needed, resulting in 89.8% of risk of negative outcomes associated with medications due to untreated health problems. The request for inclusion of drugs (66.1%) was the main intervention, and 49.2% of the medications had some action in the digestive tract or metabolism. All interventions were classified as appropriate, and 86.4% of them we able to prevent negative outcomes. Upon discharge of a transplanted patient, the orientation given by the clinical pharmacist together with the multidisciplinary team is important to avoid negative outcomes associated with drug therapy, assuring medication reconciliation and patient safety.

Foram analisadas, de acordo com sua significância e desfechos clínicos obtidos, as seguintes variáveis registradas no Banco de Dados do Serviço de Farmácia Clínica: orientações farmacêuticas na alta, problemas e resultados negativos relacionados aos medicamentos, e intervenções farmacêuticas realizadas. A primeira alta pós-transplante envolveu toda a equipe multiprofissional, sendo o farmacêutico responsável pela orientação do tratamento medicamentoso. A média de altas/mês com orientação farmacêutica no período do estudo foi de 10,6±1,3, totalizando 74 orientações. O tratamento clínico prescrito teve média de 9,1±2,7 medicamentos por paciente. Foram identificados 59 problemas relacionados aos medicamentos; 67,8% relacionaram-se com a não prescrição do medicamento necessário, acarretando 89,8% de risco de resultados negativos associados aos medicamentos por problema de saúde não tratado. A principal intervenção foi a solicitação de inclusão do medicamento (66,1%), e 49,2% dos medicamentos envolvidos agiam no aparelho digestivo/metabolismo. Todas as intervenções foram classificadas como apropriadas, e 86,4% foram capazes de prevenir o resultado negativo. A orientação do farmacêutico clínico junto à equipe multiprofissional no momento da alta do paciente transplantado é importante, pois previne resultados negativos associados à farmacoterapia, garantindo a conciliação medicamentosa e a segurança do paciente.

Depressive symptoms are a common problem among family caregivers of stroke survivors. The purpose of this study was to examine the association between care recipient's impairment and caregiver depression, and determine the possible mediating effects of caregiver negative problem-orientation, mastery, and leisure time satisfaction. The evaluated model was derived from Pearlin's stress process model of caregiver adjustment. We analyzed baseline data from 122 strained family members who were assisting stroke survivors in Germany for a minimum of 6 months and who consented to participate in a randomized clinical trial. Depressive symptoms were measured with the Center for Epidemiological Studies Depression Scale. The cross-sectional data were analyzed using path analysis. The results show an adequate fit of the model to the data, χ2(1, N = 122) = 0.17, p = .68; comparative fit index = 1.00; root mean square error of approximation: p < .01; standardized root mean square residual = 0.01. The model explained 49% of the variance in the caregiver depressive symptoms. Results indicate that caregivers at risk for depression reported a negative problem orientation, low caregiving mastery, and low leisure time satisfaction. The situation is particularly affected by the frequency of stroke survivor problematic behavior, and by the degree of their impairments in activities of daily living. The findings provide empirical support for the Pearlin's stress model and emphasize how important it is to target these mediators in health promotion interventions for family caregivers of stroke survivors.

Objective There is a high co-occurrence of problem drinking and regular cigarette smoking, and cognitive processes (e.g., motivation to use, expectations about the consequences of use) related to each are positively associated with one another. We explored drinking motives in relation to cognitive-based smoking processes among smokers with problematic drinking. We expected that drinking coping motives would be associated with smoking consequences related to negative reinforcement and negative personal outcomes, and inflexibility of smoking behavior; observed effects for coping motives would be unique from shared variance with other motives and incrementally evident beyond the variance accounted for by tobacco-related health problems, smoking rate, negative affectivity, cannabis use, and gender. Methods The sample included 195 individuals recruited into a larger study of smoking cessation treatments (i.e., they were interested in quitting), who were heavy drinkers and smoked daily. Participants were primarily male (n = 122, 63%), fairly young (Mage=30.3 years; SD=12.46), and predominantly White/Caucasian (n = 175, 80%). Roughly 57% (n = 111) had at least one comorbid Axis I disorder, the most common being social anxiety (n = 21, 11%) and generalized anxiety disorder (n = 12, 6%). Results Coping drinking motives predicted negative smoking consequences, negative reinforcement, and smoking inflexibility. Enhancement drinking motives marginally predicted positive reinforcement. Conformity drinking motives predicted smoking consequences related to appetite/weight control. Social drinking motives predicted negative reinforcement and barriers to cessation, and marginally predicted positive reinforcement. Conclusions Theoretical models and clinical activities focused on smoking cessation among problem drinkers may benefit from considering the role of drinking motives, particularly coping-oriented motives, to better understanding cognitive-based smoking processes.

2015-05-01

Coping is a dynamic physiological and psychological process in response to perceived environmental stress that functions to restore physiological homeostasis and reduce negative affect [1]. Thematic content analysis was employed for references to 13 well-established coping strategies in interviews with 20 retired long-duration male cosmonauts. As in previous research with other space samples [2,3] the retired cosmonauts mentioned Problem-Oriented strategies more frequently than Emotion-Oriented ones. In the present sample, Seeking Social Support, Planful Problem Solving and Endurance/Obedience/Effort were the top three most mentioned coping strategies. Cosmonauts who had spent more than a year in space, compared to those who had spent less than a year, mentioned using Planful Problem Solving more as they recalled their career and retirement. Examining changes over time, spaceflight had a positive effect on Accepting Responsibility. Endurance/Obedience/Effort steadily decreased over time, while we found an inverted-U pattern for Distancing and Self-Control. Additional results in relation to other astronaut samples and the relationship between coping and post-flight growth are discussed.

Understanding the Relationship Between PTSD and Social Support: The Role of Negative Network Orientation

PubMed Central

Clapp, Joshua D.; Beck, J. Gayle

2009-01-01

Network orientation is conceptualized as an individual’s attitudes and expectations regarding the usefulness of support networks in coping with stress. The present research examined the potential for network orientation to explicate the well documented association between posttraumatic stress disorder (PTSD) and attenuated social support. Data collected from survivors of serious motor vehicle trauma (N = 458) were used to test the hypothesis that severity of PTSD would hold a significant indirect relationship with social support through negative network orientation. Childhood victimization and elapsed time from the accident were examined as potential moderators of this indirect relationship. Consistent with hypotheses, path analyses demonstrated a significant indirect relationship between PTSD and social support through negative network orientation. Specifically, this indirect effect was the result of a direct association between PTSD severity and negative network orientation and an inverse association between negative network orientation and social support. This pattern of relationships was invariant across mode of PTSD assessment (interview vs. self-report). No moderation effects were noted. These data suggest that network orientation may be an important factor in understanding interface of interpersonal processes and posttrauma pathology. PMID:19162260

Posttraumatic stress disorder symptoms and attitudes about social support: Does shame matter?

PubMed

Dodson, Thomas S; Beck, J Gayle

2017-04-01

Considerable research has examined the association between posttraumatic stress disorder (PTSD) symptoms and social support. One facet of this relationship that deserves greater attention concerns trauma survivors' negative expectations towards social support, termed negative network orientation. To expand our understanding of negative network orientation, the current study examined shame as a possible mediator in the relationship between PTSD symptoms and negative network orientation, in a sample of 202 female survivors of intimate partner violence (IPV). Additionally, a history of child abuse (CA) was evaluated as a moderator of the association between shame and negative network orientation in this model. Path analyses indicated a significant indirect effect between PTSD symptoms and negative network orientation through shame, indicative of mediation. A history of CA moderated this effect, such that women with a history of CA in addition to IPV showed a significantly stronger relationship between PTSD symptoms and negative network orientation through shame, relative to women who only had a history of IPV. These findings support the relevance of shame in understanding the association between PTSD symptoms and negative beliefs about social support and highlight the role of childhood abuse as a moderator in this process among IPV survivors.

Maternal negative affect during infancy is linked to disrupted patterns of diurnal cortisol and alpha asymmetry across contexts during childhood.

PubMed

Brooker, Rebecca J; Davidson, Richard J; Goldsmith, H Hill

2016-02-01

Maternal negative affect in the early environment is believed to sensitize long-term coping capacities in children. Yet, little work has identified physiological systems associated with coping responses, which may serve as mechanisms for links between early maternal negativity and child outcomes. Using a longitudinal twin sample (N=89), we found that high levels of maternal negative affect during infancy were associated with dysregulation of diurnal cortisol and electroencephalograph (EEG) asymmetry, two physiological systems that may support active approach-oriented coping when children are 7years old. Flattened slopes of diurnal cortisol were also associated with greater numbers of concurrent overanxious behaviors in children. A mediation analysis supported the role of dysregulated diurnal cortisol as a mediator of the link between maternal negative affect in the early environment and childhood risk for anxiety problems.

Research has consistently revealed a negative relationship between chronological age and promotion orientation, that is, the motivational orientation toward approaching possible gains. In addition, experimental research has demonstrated that activating positive self-relevant stereotypes (e.g., for men, the stereotype that men are good at math) can stimulate increases in promotion orientation. Integrating and applying this research to the work context, we hypothesized that the relationship between age and promotion orientation would depend on employees' perceptions of the stereotype of older workers in their work context, such that there would be no negative relationship between age and promotion orientation when individuals perceive a more positive older worker stereotype. We analyzed the relationships between age, perceived older worker stereotype (POWS), and promotion orientation using a sample of working adults (N = 337) aged 19-64 years. Results revealed a significant age by POWS interaction such that there was a negative relationship between age and promotion orientation when POWS was less positive. However, there was no relationship between age and promotion orientation when POWS was more positive. Results suggest that the negative relationship between age and promotion orientation depends on contextual factors such as POWS.

The understanding of how lesbians, gays, and bisexuals cope with homophobic violence is limited. Therefore, on the one hand, this study focuses on avoidance, problem-oriented, and emotion-oriented coping as general coping styles. On the other hand, special attention is paid to visibility management as a coping strategy that can be applied in a heteronormative context. Moreover, the moderating role of general coping styles and visibility management in the relationship between homophobic violence and negative mental health outcomes is studied. Data were collected from 1,402 Flemish lesbians, gays, and bisexuals. Stepwise regression analyses shows that coping styles and visibility management have a direct effect on mental health; however, no evidence for a moderating effect is found. Additionally, visibility management and emotion-oriented coping are found to exert a combined effect on mental health.

This study examined the role of reflection on personal cases for making ethical decisions with regard to new ethical problems. Participants assumed the position of a business manager in a hypothetical organization and solved ethical problems that might be encountered. Prior to making a decision for the business problems, participants reflected on a relevant ethical experience. The findings revealed that application of material garnered from reflection on a personal experience was associated with decisions of higher ethicality. However, whether the case was viewed as positive or negative, and whether the outcomes, process, or outcomes and processes embedded in the experience were examined, influenced the application of case material to the new problem. As expected, examining positive experiences and the processes involved in those positive experiences resulted in greater application of case material to new problems. Future directions and implications for understanding ethical decision-making are discussed. PMID:26257506

The language of uncertainty in genetic risk communication: framing and verbal versus numerical information.

Within a group of 300 medical students, two characteristics of risk communication in the context of a decision regarding prenatal diagnosis for cystic fibrosis are manipulated: verbal versus numerical probabilities and the negative versus positive framing of the problem (having a child with versus without cystic fibrosis). Independently of the manipulations, most students were in favor of prenatal diagnosis. The effect of framing was only significant in the conditions with verbal information: negative framing produced a stronger choice in favor of prenatal diagnosis than positive framing. The framing effect in the verbal conditions and its absence in the numerical conditions are explained by the dominance of the problem-occurrence orientation in health matters as well as a recoding process which is more likely to occur in the numerical (the probability "1-P" switches to its counterpart "P") than in the verbal conditions. The implications for the practice of genetic counseling are discussed.

Utilizing Daniel Goleman's theory of emotional competence, Beck's cognitive theory, and Rudd's cognitive-behavioral theory of suicidality, the relationships between hopelessness (cognitive component), social problem solving (cognitive-behavioral component), emotional competence (emotive component), and adolescent suicidal ideation were examined. Based on the responses of 5,557 Secondary 1 to Secondary 4 students from 42 secondary schools in Hong Kong, results showed that suicidal ideation was positively related to adolescent hopelessness, but negatively related to emotional competence and social problem solving. While standard regression analyses showed that all the above variables were significant predictors of suicidal ideation, hierarchical regression analyses showed that hopelessness was the most important predictor of suicidal ideation, followed by social problem solving and emotional competence. Further regression analyses found that all four subscales of emotional competence, i.e., empathy, social skills, self-management of emotions, and utilization of emotions, were important predictors of male adolescent suicidal ideation. However, the subscale of social skills was not a significant predictor of female adolescent suicidal ideation. Standard regression analysis also revealed that all three subscales of social problem solving, i.e., negative problem orientation, rational problem solving, and impulsiveness/carelessness style, were important predictors of suicidal ideation. Theoretical and practice implications of the findings are discussed.

Parent training (PT) delivered as a guided self-help intervention may be a cost- and time-effective intervention in the treatment of children with externalizing disorders. In face-to-face PT, parenting strategies have repeatedly been identified as mediating mechanisms for the decrease of children's problem behavior. Few studies have examined possible mediating effects in guided self-help interventions for parents. The present study aimed to investigate possible mediating variables of a behaviorally oriented guided self-help program for parents of children with externalizing problems compared to a nondirective intervention in a clinical sample. A sample of 110 parents of children with externalizing disorders (80 % boys) were randomized to either a behaviorally oriented or a nondirective guided self-help program. Four putative mediating variables were examined simultaneously in a multiple mediation model using structural equation modelling. The outcomes were child symptoms of ADHD and ODD as well as child externalizing problems, assessed at posttreatment. Analyses showed a significant indirect effect for dysfunctional parental attributions in favor of the group receiving the behavioral program, and significant effects of the behavioral program on positive and negative parenting and parental self-efficacy, compared to the nondirective intervention. Our results indicate that a decrease of dysfunctional parental attributions leads to a decrease of child externalizing problems when parents take part in a behaviorally oriented guided self-help program. However, none of the putative mediating variables could explain the decrease in child externalizing behavior problems in the nondirective group. A change in dysfunctional parental attributions should be considered as a possible mediator in the context of PT.

This study investigates how personality traits in combination with frequency of and emotional reaction to negative comments about appearance while growing up are related to appearance evaluation and orientation among adult women. Nine hundred and seven participants from a representative sample of Norwegian women aged 22-55, answered questions measuring body image, personality (Big Five), and history of experiencing negative comments about appearance. Results indicated that only emotional reaction to negative comments about appearance significantly predicted both appearance evaluation and orientation, while frequency of negative comments did not. Being extrovert predicted more positive appearance evaluation and being more appearance oriented than being introvert. Scoring high on neuroticism was related to negative appearance evaluation and high appearance orientation. The findings demonstrate the importance of differentiating between the frequency and the emotional impact of teasing as well as including personality traits when studying body image.

In the current study, based on a sample of 1,873 adolescents between 11.4 and 20.9 years of age from the first 3 waves of the National Longitudinal Study of Adolescent Health, we investigated the longitudinal effects of future orientation on levels of and developmental changes in problem behaviors, while controlling for the effects by impulsivity; we also tested the moderating effects by future orientation on the impulsivity-problem behaviors link over time. Additionally, we examined future orientation operationalized by items measuring education, marriage, and life domains. Findings based on growth curve analyses provided evidence of longitudinal effects by education and life future orientation on both levels of and developmental changes in problem behaviors; the effect of marriage future orientation was not significant for either test. In addition, only life future orientation moderated the effect by impulsivity on levels of problem behaviors over time. More specifically, impulsivity had a weaker effect on levels of problem behaviors over time for adolescents who reported higher levels of life future orientation.

To compare the efficacy of problem-solving therapy (PST) combined with behavioral sleep strategies to standard cognitive therapy (CT) combined with behavioral sleep strategies in the treatment of insomnia. A six-week randomized controlled trial with one month follow-up. The Australian National University Psychology Clinic, Canberra, Australia. Forty-seven adults aged 18-60 years recruited from the community meeting the Research Diagnostic Criteria for insomnia. Participants received 6 weeks of treatment including one group session (sleep education and hygiene, stimulus control instructions and progressive muscle relaxation) followed by 5 weeks of individual treatment of PST or CT. Primary outcomes included sleep efficiency (SE) from sleep diaries, the Insomnia Severity Index (ISI), and the Pittsburgh Sleep Quality Index (PSQI). Secondary measures assessed dysfunctional sleep beliefs, problem-solving skills and orientations, and worry. Both treatments produced significant post therapy improvements in sleep which were maintained at 1 month follow-up (on SE Cohen d = 1.42, 95% CI 1.02-1.87 for PST; d = 1.26, 95% CI 0.81-1.65 for CT; on ISI d = 1.46, 95% CI 1.03-1.88 for PST; d = 1.95, 95% CI 0.52-2.38 for CT; for PSQI d = 0.97, 95% CI 0.55-1.40 for PST and d = 1.34, 95% CI 0.90-1.79 for the CT). There were no differences in PST and CT in the size or rate of improvement in sleep although CT produced a significant faster rate of decline in negative beliefs about sleep than PST and there was a trend (P = 0.08) for PST to produce a faster rate of improvement in negative problem orientation than CT. The results provide preliminary support for problem solving treatment as an equally efficacious alternative component to cognitive therapy in psychological interventions for insomnia.

Inadequate Models of Adolescent Substance Use Prevention: Looking for Options to Promote Pro-Social Change and Engagement.

PubMed

Ostaszewski, Krzysztof

2015-01-01

In the adolescent substance use prevention two competing models can be found: negative and positive. The negative model is entirely focused on risks and problems that young people should avoid. The positive model goes beyond that problem-oriented perspective and calls for positive youth growth and development. Both models of prevention seems to be inadequate to address effectively the challenging problem of adolescent substance use associated consequences. Both models are in fact flawed, but in different ways. Old, negative model neglects the power of individual strengths and ecological developmental assets, while new, positive model is often instrumentally used by politicians and other stakeholders for completely different goals than an informed, science-based prevention. As a result many substance use prevention programs implemented at schools and in communities are neither theoretically nor empirically informed. In order to address these flaws, the model of balanced prevention was outlined. It posits that triple well informed efforts are needed to achieve both specific substance use prevention goals and youth personal/social development. These efforts include protection building, risks reducing and individual assets development support. The proposed model is an ongoing work in progress. It can be considered as an encouragement for international dialogue to build a balanced conceptual foundation for adolescent substance use prevention.

Implicit and explicit measures of sexual orientation attitudes: in group preferences and related behaviors and beliefs among gay and straight men.

The relations among implicit and explicit measures of sexual orientation attitudes and sexual-orientation-related behavior and beliefs among gay men (Study 1) and straight men (Studies 1 and 2) were explored. Study 1 found relations between implicit and explicit measures of sexual orientation attitudes, large differences between gay and straight men on both implicit and explicit measures, and that these measures predicted sexual-orientation-related behaviors among gay men. Also, only straight men exhibited a negative relation between their attitudes toward homosexuality and heterosexuality. Study 2 found that as straight men held more negative attitudes toward homosexuality, they more strongly endorsed the importance of heterosexual identity and of traditional masculine gender roles. These endorsements mediated the negative relation between their attitudes toward heterosexuality and homosexuality. Implications for assessing attitudes toward sexual orientation and their relations for sexual orientation identity are discussed.

Reduced amplitude of the P300 event-related potential has been consistently associated with a variety of externalising problems, including conduct disorder. The few available genetically-informative studies of these relationships, however, were conducted among adolescents/adults (i.e., at an age when conduct disorder has typically already become manifest). Among 200 general population twins with a mean age of 9 years (range 6-14 years), we studied the relationship between the P300 waveform elicited by an auditory oddball task and the DSM-oriented conduct problems scale of the Child Behavior Checklist 6-18. Conduct problems scores were negatively and significantly correlated (r = -0.19, p = 0.01) with P300 amplitude; correlations between P300 amplitude and the other DSM-oriented Child Behavior Checklist scales were non-significant, except for oppositional defiant problems (p = 0.01). We found moderate heritability estimates for both P300 amplitude (0.58, CI:0.37;0.73) and conduct problems (0.52, CI:0.25;0.70). Bivariate twin analyses indicated that the covariation between these two phenotypes can be explained by additive genetic factors only, with a genetic correlation of -0.33. An association between reduced P300 amplitude and conduct problems can be substantiated already in childhood, at an age that precedes the most typical onset of conduct disorder. This relationship appears to be genetic in nature. Reduced P300 amplitude can represent a valuable marker for conduct problems, and can contribute to the early identification of children at high-risk for conduct disorder.

The authors investigated the effects on job performance of 3 forms of goal orientation and 4 self-regulation (SR) tactics. In a longitudinal field study with salespeople, learning and performance-prove goal orientation predicted subsequent sales performance, whereas performance-avoid goal orientation negatively predicted sales performance. The SR tactics functioned as mediating variables between learning and performance-prove goal orientations and performance. Social competence and proactive behavior directly and positively predicted sales performance, and emotional control negatively predicted performance. (c) 2006 APA, all rights reserved.

A significant proportion of all deaths globally can be attributed to alcohol consumption. Although a range of correlates of alcohol consumption have already been identified at the individual level, less is understood about correlates at the macro level, such as cultural values. As a development in this understanding may prove useful for global health organizations aiming to tackle the problems associated with excessive drinking, our aim was to investigate the association between encultured alcohol consumption and Cultural Value Orientations. We obtained data describing average alcohol consumption and Cultural Value Orientations, for 74 countries, from an online data repository. To assess whether Cultural Value Orientations are associated with alcohol consumption we calculated partial correlations and performed a ridge regression analysis. Our analyses revealed that Cultural Value Orientations were significantly associated with alcohol consumption, even after controlling for average income and education level. A profile emerged in which values of autonomy and harmony were shown to be positively associated with alcohol consumption, and hierarchy and embeddedness negatively associated with alcohol consumption. The effect was modified by gender. Changes in cultural Harmony, Mastery, Autonomy and Egalitarianism were associated with increases in alcohol consumption in males, but not females, while changes in cultural Embeddedness and Hierarchy were associated with decreases in consumption in females, but no change in males. Finally, we demonstrate that latitude, and by extension its covariates such as climatic demands, partially accounted for the effect of harmony and affective autonomy on alcohol consumption. This research highlights that cultural values, and their interaction with gender, should be an important consideration for international public health organizations aiming to tackle the problems associated with alcohol consumption, but that future research is required to fully understand the link between cultural values and alcohol.

In this study, we explored the role of sex as an effect-modifying variable in the association between sexual orientation and mental health in Mexican youth. In addition, we tested if violent experiences in the family and the school and attitudes toward homosexuality could act as mediating variables in such association. Data from three representative surveys performed in 2007, 2009, and 2013 among Mexican high school students were analyzed. Two dimensions of sexual orientation were evaluated: romantic partnership and sexual behavior. The outcomes were negative and positive mood, suicidal ideation and intent, self-concept, and self-esteem. There were differences by gender because in males, there were more disparities in mental health associated with sexual orientation (suicidal ideation and attempt, negative and positive mood, negative self-concept, and family-related self-esteem) than in females (suicidal ideation and negative mood). Experiences of school violence were mediators in the relationship between sexual orientation and most health outcomes in males.

Adolescent identity and parent-adolescent conflict have each attracted considerable research interest. However, few studies have examined the important link between the two constructs. The present study examined the associations between adolescent identity processing styles and adolescent conflict resolution styles in the mother-adolescent dyad. Questionnaires about conflict frequency and resolution were completed by 796 adolescents (66% female, mostly Caucasian) and their mothers. Adolescents also completed a measure on identity styles. Each identity style was hypothesized to relate to a specific conflict resolution behavior. Hierarchical regression analyses showed that the information-oriented identity style was positively associated with positive problem solving and negatively with conflict engagement and withdrawal, the normative style was positively associated with compliance, and, finally, the diffuse-avoidant style was positively associated with withdrawal and conflict engagement and negatively with positive problem solving. Our results demonstrated that the way in which adolescents tackle identity-relevant issues is related to the way in which they deal with conflicts with their mothers. Implications and suggestions for future research are discussed.

Investigated the effects of self-regulation as a moderator of the relations between coping efforts and psychological symptoms of children of divorce. The interactions of two dimensions of self-regulation (task orientation and approach-flexibility) and two dimensions of coping (active and avoidant) predicting children's postdivorce symptoms were tested using a sample of 199 divorced mothers and their children, ages 8 to 12. The approach-flexibility dimension moderated the relations of both active and avoidant coping with children's self-report of anxiety. At higher levels of approach-flexibility, active coping was negatively related to anxiety, while at lower levels of approach-flexibility, active coping was unrelated to anxiety. Avoidant coping was unrelated to anxiety at higher levels of approach-flexibility, whereas at lower levels of approach-flexibility, avoidant coping was positively related to anxiety. The task orientation dimension did not interact with coping, but had direct, independent effects on children's self-report of conduct problems, depression, and parent-report of internalizing and externalizing behavior problems. The implications for understanding children's coping with divorce and future directions for research are discussed.

Recent experimental studies show that emotions can have a significant effect on the way we think, decide, and solve problems. This paper presents a series of four experiments on how emotions affect logical reasoning. In two experiments different groups of participants first had to pass a manipulated intelligence test. Their emotional state was altered by giving them feedback, that they performed excellent, poor or on average. Then they completed a set of logical inference problems (with if p, then q statements) either in a Wason selection task paradigm or problems from the logical propositional calculus. Problem content also had either a positive, negative or neutral emotional value. Results showed a clear effect of emotions on reasoning performance. Participants in negative mood performed worse than participants in positive mood, but both groups were outperformed by the neutral mood reasoners. Problem content also had an effect on reasoning performance. In a second set of experiments, participants with exam or spider phobia solved logical problems with contents that were related to their anxiety disorder (spiders or exams). Spider phobic participants' performance was lowered by the spider-content, while exam anxious participants were not affected by the exam-related problem content. Overall, unlike some previous studies, no evidence was found that performance is improved when emotion and content are congruent. These results have consequences for cognitive reasoning research and also for cognitively oriented psychotherapy and the treatment of disorders like depression and anxiety.

This study examined (a) the main and interactive effects of goal orientations and perceived motivational climate on prosocial and antisocial behaviour, and (b) whether number of seasons one has played for the team interacts with motivational climate in predicting prosocial and antisocial behaviour in association football. Participants were 325 male association football players, whose age ranged from 12 to 17 years. Athletes completed questionnaires measuring frequency of prosocial and antisocial behaviours in football, goal orientation, motivational climate and social desirability, and indicated the number of seasons they had played for their current team. Regression analyses revealed that task orientation and mastery climate were positive predictors of prosocial behaviour, whereas ego orientation and performance climate were positive predictors of antisocial behaviour. In addition, task orientation negatively predicted antisocial behaviour, while ego orientation negatively predicted prosocial behaviour. No significant interactions between task and ego orientation and mastery and performance motivational climate were found. Finally, mastery climate negatively predicted antisocial behaviour for those who had played many seasons for the team. In conclusion, strengthening task orientation and mastery climate and weakening ego orientation may enhance prosocial behaviour. However, for antisocial conduct to be eliminated from the context of association football, ego orientation and performance climate need to be tempered, as these constructs exert unique independent effects on antisocial behaviour.

Individualism and collectivism are cultural syndromes that have been associated with adolescent problem behavior in studies conducted in the U.S. and Southeast Asia. However, research investigating the mechanisms of how cultural orientation impacts health risk behaviors has been limited. This study tested a new model explaining the relationship between cultural orientation (i.e., individualism, collectivism) and adolescent problem behavior (i.e., substance use and risky sex) in terms of interpersonal self-regulation (i.e., social self-control). As such, the study is rooted in theories of the role of culture in developing self-regulation. Participants were high school students (N = 716) from the Bashkirtostan Republic of the Russian Federation. Adolescents from the Russian Federation tend to show high prevalence of cigarette smoking and binge drinking. People of the Russian Federation in general are traditionally collectivist in orientation, although increased globalization and post-Soviet capitalism may indicate high individualist values in younger generation Russians. Using path analysis we found that in addition to having direct effects, higher individualism indirectly affected substance use and risky sexual behavior through social self-control and negative life events. Higher collectivism was found to have a direct protective effect on risky sexual behavior and a direct effect on social self-control. However, collectivism was not found to have indirect effects on substance use or risky sexual behavior. Higher individualism appears to function as a risk factor for adolescent problem behavior and this relationship may be mediated by lower social self-control. Culturally-tailored prevention programs utilizing the individualism-collectivism framework may benefit from addressing social self-control.

To investigate the applicability of psychodrama orientated group work among the elderly living in nursing homes, and effect of this group work on coping with psychological and behavioral problems. Eleven male volunteers were chosen for the group. None of them had any negative features on communicating with others or had somatic or serious psychological problems. Eighteen psychodrama orientated group work sessions were held. Each was 2.5 to 3 hours long and took place only once a week. The staff of the nursing home became involved in the process after the twelfth session. Therapists registered their observations at every meeting. To evaluate the anxiety-depression levels the Geriatric Depression Scale and Hamilton Anxiety Rating Scale were used. Due to a late warm up among the members in this group, dramatization took place in later sessions. During the study, an increase in the members' spontaneity, creativity and empathy and consequently an improvement in communicating with and helping others, and coping with problems were observed. Articulation of emotions and thoughts improved gradually during the study. Somatic and total anxiety scores decreased significantly. This study shows that psychodrama group work can be used with the elderly and it may be helpful for improving psychological and behavioral areas, and for discovering the meaning of life.

This article examines the role of motivational factors in affective forecasting. The primary hypothesis was that people predict positive emotional reactions to future events when they are motivated to enhance their current feelings. Three experiments manipulated participants' moods (negative vs. neutral) and orientation toward their moods (reflective vs. ruminative) and then assessed the positivity of their affective predictions for future events. As hypothesized, when participants adopted a reflective orientation, and thus should have been motivated to engage in mood-regulation processes, they predicted more positive feelings in the negative than in the neutral mood condition. This pattern of mood-incongruent affective prediction was not exhibited when participants adopted a ruminative orientation. Additionally, within the negative mood condition, generating affective forecasts had a more positive emotional impact on reflectors than on ruminators. The findings suggest that affective predictions are sometimes driven by mood-regulatory motives.

Recent research indicates that some dimensions of perfectionism are positively related to athlete burnout, whereas others are negatively related to athlete burnout. The divergent relationship between these dimensions of perfectionism and athlete burnout may be explained by different coping tendencies. The present investigation examined whether different coping tendencies mediate the relationship between self-oriented and socially prescribed perfectionism and burnout. Two-hundred and six junior elite athletes (M age=15.15 years, SD=1.88 years, range=11-22 years) completed measures of self-oriented and socially prescribed perfectionism, coping tendencies, and athlete burnout. Structural equation modeling indicated that the relationship between dimensions of perfectionism and athlete burnout was mediated by different coping tendencies. Higher levels of socially prescribed perfectionism was related to higher levels of avoidant coping which, in turn, was related to higher levels of athlete burnout. In contrast, higher levels of self-oriented perfectionism was related to higher levels of problem-focused coping and lower levels of avoidant coping which, in turn, was related to lower levels of athlete burnout. The findings suggest that different coping tendencies may underpin the divergent relationship between self-oriented and socially prescribed dimensions of perfectionism and athlete burnout.

Self-reported self-esteem, life orientation, satisfaction with life, and bullying were examined in relation to victimization experiences among 54 students who stuttered and 54 students who did not stutter. Those who stuttered reported greater, i.e., clinically significant, victimization (44.4%) than students who did not stutter (9.2%). Significant differences were found between means for self-esteem and life orientation, with students who stuttered reporting lower self-esteem and less optimistic life orientation than those who did not stutter. In both groups of students, high victimization scores had statistically significant negative correlations with optimistic life orientation, high self-esteem, and high satisfaction with life scores. Given the increased likelihood of students who stuttered being bullied, the negative relation of adjustment variables and bullying, and the potentially negative long-term effects of bullying, increased vigilance and early intervention are discussed.

Problem drinking during college is a well-known phenomenon. However, predictors of progression to problematic drinking, particularly among ethnic minorities such as Mexican Americans, have received limited research attention. The current study compared the rates and predictors of problem drinking progression from the first to the second year of college among four groups: Mexican American men, Mexican American women, White European men, and White European women (N = 215). At baseline, participants were all first-year college students who scored as nonproblem drinkers on the Young Adult Alcohol Problems Screening Test (YAAPST). Participants were classified as progressors or stable nondrinkers/nonproblem drinkers based on YAAPST scores 12 months later. Hypothesized predictors of progression included behavioral undercontrol, negative emotionality, alcohol use expectancies, and cultural orientation (Mexican American sample only). Differences were anticipated between gender and ethnic groups in both progression rates and predictors of progression. Twenty-nine percent of the sample progressed to problematic drinking; however, no differences emerged by gender or ethnicity. For the full sample, higher behavioral undercontrol and higher negative emotionality significantly predicted progression. Differences in predictors were not found across gender and ethnic subgroups. The hypothesis that rates of progression to problem drinking would differ among the four gender and ethnic groups was not supported. Thus, although White European men are most often identified as at high risk for alcohol use problems, the present findings indicate that women and Mexican American students also should be targeted for prevention and/or intervention.

A flexible influence of affective feelings on creative and analytic performance.

PubMed

Huntsinger, Jeffrey R; Ray, Cara

2016-09-01

Considerable research shows that positive affect improves performance on creative tasks and negative affect improves performance on analytic tasks. The present research entertained the idea that affective feelings have flexible, rather than fixed, effects on cognitive performance. Consistent with the idea that positive and negative affect signal the value of accessible processing inclinations, the influence of affective feelings on performance on analytic or creative tasks was found to be flexibly responsive to the relative accessibility of different styles of processing (i.e., heuristic vs. systematic, global vs. local). When a global processing orientation was accessible happy participants generated more creative uses for a brick (Experiment 1), successfully solved more remote associates and insight problems (Experiment 2) and displayed broader categorization (Experiment 3) than those in sad moods. When a local processing orientation was accessible this pattern reversed. When a heuristic processing style was accessible happy participants were more likely to commit the conjunction fallacy (Experiment 3) and showed less pronounced anchoring effects (Experiment 4) than sad participants. When a systematic processing style was accessible this pattern reversed. Implications of these results for relevant affect-cognition models are discussed.

Mental health of lesbian, gay, and bisexual youth: A developmental resiliency perspective

2011-01-01

Research suggests that lesbian, gay, and bisexual (LGB) youth are at increased risk for both victimization and internalizing mental health problems, but limited research has studied their association or factors that increase resilience. The sample included 425 LGBs between the ages of 16 and 24 year. The majority had disclosed their sexual orientation to family or friends (98%) and 97% had someone in their lives who was accepting. Racial/ethnic minority and female participants in general reported lower levels of disclosure and acceptance. Most participants reported some form of sexual orientation-related victimization (94%). Victimization was associated with psychological distress, but a compensatory model indicated that in the context of this victimization both peer and family support had significant promotive effects. A test of a protective model found social support did not ameliorate negative effects of victimization. The positive effects of family support decreased with age. Peer and family support were particularly important, but they did not significantly dampen the negative effects of victimization. Our findings suggest that mental health professionals working with LGB youth should address social support and that public health approaches are needed to reduce levels of victimization.

Dental care seeking behaviour is often driven by symptoms. The value of oral health related quality of life (OHRQoL) measures to predict utilisation of dental services is unknown. This study aims to explore the association between OHRQoL and problem-oriented dental attendance among adults. We analysed cross-sectional data for 705 adults, aged 16 years and above, living in three boroughs of Inner South East London. Data were collected during structured interviews at home. The short form of the Oral Health Impact Profile (OHIP-14) was used to assess the frequency of oral impacts on daily life in the last year. Problem-oriented attendance was defined based on time elapsed since last visit (last 6 months) and reason for that visit (trouble with teeth). The association between OHIP-14 (total and domain) scores and problem-oriented attendance was tested in logistic regression models adjusting for participants' sociodemographic characteristics. Problem-oriented attenders had a higher OHIP-14 total score than regular attenders (6.73 and 3.73, respectively). In regression models, there was a positive association between OHIP-14 total score and problem-oriented attendance. The odds of visiting the dentist for trouble with teeth were 1.07 greater (95% Confidence Interval: 1.04-1.10) per unit increase in the OHIP-14 total score, after adjustment for participants' sociodemographic characteristics. In subsequent analysis by OHIP-14 domains, greater scores in all domains but handicap were significantly associated with problem-oriented attendance. This study shows that oral impacts on quality of life are associated with recent problem-oriented dental attendance among London adults. Six of the seven domains in the OHIP-14 questionnaire were also associated with dental visits for trouble with teeth.

Turnover among registered nurses (RNs) produces a negative impact on the health outcomes of any health care organization. It is also recognized universally as a problem in the nursing profession. Little is known about the turnover intentions and career orientations of RNs working in Calgary, Alberta, Canada. The aim of this study is to contribute to the knowledge of and to advance the discussion on the turnover of nursing professionals. The study population consisted of RNs employed in the five major hospitals in Calgary. There were 193 surveys returned, representing a response rate of 77.2%. The results show that age and education have a negative effect on turnover intention. Education was found to have a significant negative effect on career satisfaction but not on job satisfaction and organizational commitment. Length of service has a significant negative effect on turnover intention. Role ambiguity has significant highly negative effect on career satisfaction. Growth opportunity and supervisor support have a very significant positive effect on job satisfaction, career satisfaction, and organizational commitment. External career opportunities and organizational commitment do not seem to have a significant effect on turnover intention. Career satisfaction, on the other hand, had negative significant effects on turnover intention.

The impact of childhood emotional abuse and experiential avoidance on maladaptive problem solving and intimate partner violence.

PubMed

Bell, Kathryn M; Higgins, Lorrin

2015-04-16

The purpose of the current study was to examine the joint influences of experiential avoidance and social problem solving on the link between childhood emotional abuse (CEA) and intimate partner violence (IPV). Experiential avoidance following CEA may interfere with a person's ability to effectively problem solve in social situations, increasing risk for conflict and interpersonal violence. As part of a larger study, 232 women recruited from the community completed measures assessing childhood emotional, physical, and sexual abuse, experiential avoidance, maladaptive social problem solving, and IPV perpetration and victimization. Final trimmed models indicated that CEA was indirectly associated with IPV victimization and perpetration via experiential avoidance and Negative Problem Orientation (NPO) and Impulsivity/Carelessness Style (ICS) social problem solving strategies. Though CEA was related to an Avoidance Style (AS) social problem solving strategy, this strategy was not significantly associated with IPV victimization or perpetration. Experiential avoidance had both a direct and indirect effect, via NPO and ICS social problem solving, on IPV victimization and perpetration. Findings suggest that CEA may lead some women to avoid unwanted internal experiences, which may adversely impact their ability to effectively problem solve in social situations and increase IPV risk.

In medical education, student distress is known to hamper learning and professional development. To address this problem, recent studies aimed at helping students cope with stressful situations. Undergraduate students in clinical practice frequently use experiences of surrounding peers to estimate their abilities to master such challenging situations. This use of the experiences of others, known as social comparison, may affect student distress both positively and negatively. To find characteristics of a beneficial use of social comparison, we examined differences in comparison behaviours between students expressing low and high levels of distress. The participants in our study, response rate 93% (N = 301/321), were all medical students in their first year in clinical practice. They completed the General Health Questionnaire (GHQ-12) to measure distress, and three separate questionnaires to measure: (1) orientation to comparison, (2) motive for comparison, and (3) interpretation of comparison. Differences were analysed using multivariate analysis of variance. Although all students were oriented towards social comparison, the analyses showed that this orientation was less apparent among low-distress students. Besides, the low-distress students were less inclined to use motives indicative for comparisons with peers perceived as performing worse and were less negative in the interpretations of their comparisons. As social comparison is frequently used among all students, we recommend to make them aware of their comparison behaviours and inform them about the pros and cons of the distinguished aspects of the comparison process.

Low subjective social status (SSS) in childhood places one at greater risk of a number of health problems in adulthood. Theoretical and empirical evidence indicates that exposure to supportive parenting may buffer the negative effects of low childhood SSS on adult health. Given the importance of supportive caregivers and close others for the development of attachment orientations throughout the lifespan, attachment theory may be important for understanding why some individuals are resilient to the negative effects of low childhood SSS on adult health while others are not. We examined if attachment anxiety and attachment avoidance altered the association between childhood subjective social status (SSS) and length of telomeres in white blood cells in adulthood. Shorter telomere length is associated with increased risk of age-related diseases including cancer, type 2 diabetes, and cardiovascular disease. Participants (N = 128) completed self-report measures of childhood SSS and attachment orientations, as well as a blood draw. We found that among those with low childhood SSS, low attachment anxiety was associated with longer telomere length in white blood cells in comparison to high attachment anxiety controlling for participant age, sex, race, body mass index, and adult SSS. Among those with high childhood SSS, low attachment anxiety was associated with a slight decrease in telomere length. Attachment avoidance was unrelated to length of telomeres. Such findings provide further evidence for the role that close relationships may have on buffering SSS related health disparities. © 2018 Wiley Periodicals, Inc.

Cancer and its treatments have been shown to have a negative psychological effect on many cancer patients. One of these effects is often described as body image disturbance. Due to the limited number of studies in this area, this study was performed to assess body image in cancer patients and its association with clinical variables. This was a descriptive and correlational research that was designed in Sayyed-Al-Shohda Hospital affiliated to Isfahan University of Medical Sciences, Iran in 2013. Two hundred and ten adult patients who had been suffering from cancer were selected and completed the personal/demographic/illness questionnaire and the multi-dimensional body-self relations questionnaire that contained 64-items with appearance orientation, appearance evaluation, fitness evaluation, fitness orientation, health evaluation, health orientation, illness orientation, body areas satisfaction, self-classified weight and overweight preoccupation sub-scales. Data were analyzed by ANOVA and Pearson correlation with a significance level of P < 0.05. The mean (standard deviation (scores of body image in cancer patients was 184.40 (43.68) indicating that 58.3% of them had negative body image. In addition, most of patients had negative health evaluation (60.2%), negative appearance evaluation (63%), negative illness orientation (61%), and negative fitness orientation (56%). Furthermore, there were no significant correlations between type of cancer ( P = 0.5, f = 0.3), kind of treatment ( P = 0.8, f = 5.2) and duration of illness with body image ( P = 0.6, r = -0.2). In this study most of the cancer patients had body image disturbances. Also, body image in this group wasn't associated with the type of cancer, kind of treatment and duration of illness. Totally, these results underscore the importance of assessing and treating body image disturbance in cancer patients.

Background Elevated depression and stress have been linked to greater levels of alcohol problems among young adults even after taking into account drinking level. The current study attempts to elucidate variables that might mediate the relation between symptoms of depression and stress and alcohol problems, including alcohol demand, future time orientation, and craving. Methods Participants were 393 undergraduates (60.8% female, 78.9% White/Caucasian) who reported at least 2 binge drinking episodes (4/5+ drinks for women/men, respectively) in the previous month. Participants completed self-report measures of stress and depression, alcohol demand, future time orientation, craving, and alcohol problems. Results In separate mediation models that accounted for gender, race, and weekly alcohol consumption, future orientation and craving significantly mediated the relation between depressive symptoms and alcohol problems. Alcohol demand, future orientation, and craving significantly mediated the relation between stress symptoms and alcohol problems. Conclusions Heavy drinking young adults who experience stress or depression are likely to experience alcohol problems and this is due in part to elevations in craving and alcohol demand, and less sensitivity to future outcomes. Interventions targeting alcohol misuse in young adults with elevated levels of depression and stress should attempt to increase future orientation and decrease craving and alcohol reward value.

2012-01-01

Objectives This study examined the links between maltreatment, posttraumatic stress symptoms, ethnicity-specific factors (i.e., perceived discrimination, ethnic identity, and ethnic orientation), and alcohol and/or other drug (AOD) problems among adolescent girls. Methods These relations were examined using archived data from a community sample of 168 Black and Hispanic adolescent girls who participated in a school-based substance use intervention. Results The results revealed that maltreatment was linked to AOD problems, but only through its relation with posttraumatic stress symptoms; maltreatment was positively related to posttraumatic stress symptoms, which were positively related to AOD problems. Both perceived discrimination and ethnic orientation were significant moderators. Specifically, greater perceived discrimination was associated with an increased effect of maltreatment on posttraumatic stress symptoms. Ethnic orientation demonstrated protective properties in the relation between maltreatment and AOD problem severity, such that the effect of maltreatment on AOD problem severity was less for girls with average to high ethnic orientation compared to girls with low ethnic orientation. Conclusions The findings of this study underscore the importance of developing interventions for Black and Hispanic girls that target maltreatment and AOD use concurrently and address ethnicity-specific factors.

This paper was conducted to determine the optimal travel routes for self-drive tourism based on the allocation of time and expense by maximizing the amount of attraction scores assigned to each city involved. Self-drive tourism represents a type of tourism where tourists hire or travel by their own vehicle. It only involves a tourist destination which can be linked with a network of roads. Normally, the traveling salesman problem (TSP) and multiple traveling salesman problems (MTSP) method were used in the minimization problem such as determination the shortest time or distance traveled. This paper involved an alternative approach for maximization method which is maximize the attraction scores and tested on tourism data for ten cities in Kedah. A set of priority scores are used to set the attraction score at each city. The classical approach of the orienteering problem was used to determine the optimal travel route. This approach is extended to the team orienteering problem and the two methods were compared. These two models have been solved by using LINGO12.0 software. The results indicate that the model involving the team orienteering problem provides a more appropriate solution compared to the orienteering problem model.

Positive psychological determinants of treatment adherence among primary care patients.

2015-07-01

Patient adherence to medical treatment recommendations can affect disease prognosis, and may be beneficially or deleteriously influenced by psychological factors. Aim We examined the relationships between both adaptive and maladaptive psychological factors and treatment adherence among a sample of primary care patients. One hundred and one rural, primary care patients completed the Life Orientation Test-Revised, Trait Hope Scale, Future Orientation Scale, NEO-FFI Personality Inventory (measuring positive and negative affect), and Medical Outcomes Study General Adherence Scale. In independent models, positive affect, optimism, hope, and future orientation were beneficially associated with treatment adherence, whereas pessimism and negative affect were negatively related to adherence. In multivariate models, only negative affect, optimism and hope remained significant and, in a comparative model, trait hope was most robustly associated with treatment adherence. Therapeutically, addressing negative emotions and expectancies, while simultaneously bolstering motivational and goal-directed attributes, may improve adherence to treatment regimens.

Sexual Orientation as a Peripheral Cue in Advertising: Effects of Models' Sexual Orientation, Argument Strength, and Involvement on Responses to Magazine Ads.

2017-10-12

This study examines how sexual orientation of couples featured in magazine advertisements affects heterosexual viewers' responses using the elaboration likelihood model as a framework. A 3 × 2 × 2 × 3 experiment tested effects of sexual orientation, argument strength, involvement, and attitudes toward homosexuality on heterosexuals' attitudes toward the couple, advertisement, brand, and product, purchase intentions, and recall. Results indicate that consumers were accepting of ads with lesbian portrayals. Participants showed more negative attitudes toward gay male portrayals, but attitudes toward heterosexual and lesbian ads were similar. This effect was moderated by participants' attitudes toward homosexuals. Low-involvement consumers showed more negative attitudes toward homosexual portrayals than toward heterosexual portrayals, indicating that sexual orientation may have served as a peripheral cue negatively impacting attitudes toward the couple and ad under low elaboration. These effects were not observed for attitudes toward the brand and product, purchase intentions, or recall.

Sexual orientation was examined as a moderator in the relation between biological sex and interpersonal problems. Participants were 60 lesbians, 45 heterosexual women, 37 gay men, and 39 heterosexual men, who completed the Inventory of Interpersonal Problems-Circumplex. Sexual orientation was found to moderate one of the eight interpersonal problems under study. Heterosexual women scored significantly higher than lesbian women in Non-assertive. Although hypothesized, gay men did not differ from heterosexual men along the Dominant-Cold quadrant. Implications of these results are discussed.

Mental health concerns of gay and bisexual men seeking mental health services.

Berg, Michael B; Mimiaga, Matthew J; Safren, Steven A

Little data exist about the mental health needs of gay and bisexual men. This is due to limitations of existing studies such as small and nonrepresentative samples, failure to assess sexual orientation, and concerns about stigmatization, possibly causing sexual minority individuals to be reluctant to disclose their sexual orientation to researchers. Fenway Community Health is a large urban health center that serves the LGBT community. The large number of gay and bisexual men who present for mental health treatment allows for a unique opportunity to gain insight into mental health, prevention, and intervention needs for this group. The current study is a review of the mental health information from all of the gay and bisexual men who reported that they were HIV-negative during their mental health intake over a six-month period at Fenway Community Health (January to June 2000; N = 92). The most frequent presenting problems were depression, anxiety, and relationship issues. Additionally, presenting problems included current or past abuse, substance abuse, finance and employment, recent loss, and family issues. The most frequent diagnoses were depression, anxiety disorders, and adjustment disorders. These findings support the notion that presenting problems and mental health concerns among gay and bisexual men are similar to those frequently reported by individuals in other mental health facilities, however, specific psychosocial stressors are unique to this population.

Personality traits, namely neuroticism, have been suggested as vulnerability factors for the development and maintenance of sexual dysfunction in heterosexual samples. However, no evidence was found regarding homosexual samples. This study aimed to analyze the differences on personality traits between heterosexual and homosexual men and women with and without sexual problems. Participants were 285 individuals (142 men, 143 women) who completed a web-based survey. Participants answered the NEO Five-Factor Inventory, the Brief Symptomatology Inventory, and questions regarding sexual problems. The groups of men and women with and without sexual problems were matched for sociodemographic variables. A 2 (Group) × 2 (Sexual Orientation) multivariate analysis of covariance was conducted separately for each gender. Results indicated a significant main effect for group and for sexual orientation in male and female samples. Men with sexual problems scored higher on neuroticism, whereas women with sexual problems scored higher on neuroticism and lower on extraversion when compared with healthy controls, regardless of sexual orientation. In addition, gay men scored higher on neuroticism and lesbian women scored higher on conscientiousness compared with the heterosexual groups. The present findings emphasize the central role of neuroticism on sexual problems in both men and women regardless of sexual orientation.

Veterans with posttraumatic stress disorder (PTSD) and major depressive disorder (MDD), the two most prevalent mental health disorders in the Iraq and Afghanistan veterans, are at increased risk for cannabis use and problems including cannabis use disorder (CUD). The present study examined the relationship of PTSD and MDD with cannabis use frequency, cannabis problems, and CUD as well as the role of three coping-oriented cannabis use motives (coping with negative affect, situational anxiety, and sleep) that might underlie this relationship. Participants were veterans (N = 301) deployed post 9/11/2001 recruited from Veterans Health Administration facility in the Northeast US based on self-reported lifetime cannabis use. There were strong unique associations between PTSD and MDD and cannabis use frequency, cannabis problems, and CUD. Mediation analyses revealed the three motives accounted, in part, for the relationship between PTSD and MDD with three outcomes in all cases but for PTSD with cannabis problems. When modeled concurrently, sleep motives, but not situational anxiety or coping with negative affect motives, significantly mediated the association between PTSD and MDD with use. Together with coping motives, sleep motives also fully mediated the effects of PTSD and MDD on CUD and in part the effect of MDD on cannabis problems. Findings indicate the important role of certain motives for better understanding the relation between PTSD and MDD with cannabis use and misuse. Future work is needed to explore the clinical utility in targeting specific cannabis use motives in the context of clinical care for mental health and CUD. PMID:27786514

Evaluating Perceived Probability of Threat-Relevant Outcomes and Temporal Orientation in Flying Phobia.

2016-01-01

Probability bias regarding threat-relevant outcomes has been demonstrated across anxiety disorders but has not been investigated in flying phobia. Individual temporal orientation (time perspective) may be hypothesised to influence estimates of negative outcomes occurring. The present study investigated whether probability bias could be demonstrated in flying phobia and whether probability estimates of negative flying events was predicted by time perspective. Sixty flying phobic and fifty-five non-flying-phobic adults were recruited to complete an online questionnaire. Participants completed the Flight Anxiety Scale, Probability Scale (measuring perceived probability of flying-negative events, general-negative and general positive events) and the Past-Negative, Future and Present-Hedonistic subscales of the Zimbardo Time Perspective Inventory (variables argued to predict mental travel forward and backward in time). The flying phobic group estimated the probability of flying negative and general negative events occurring as significantly higher than non-flying phobics. Past-Negative scores (positively) and Present-Hedonistic scores (negatively) predicted probability estimates of flying negative events. The Future Orientation subscale did not significantly predict probability estimates. This study is the first to demonstrate probability bias for threat-relevant outcomes in flying phobia. Results suggest that time perspective may influence perceived probability of threat-relevant outcomes but the nature of this relationship remains to be determined.

The present study investigated whether probability bias could be demonstrated in flying phobia and whether probability estimates of negative flying events was predicted by time perspective. Sixty flying phobic and fifty-five non-flying-phobic adults were recruited to complete an online questionnaire. Participants completed the Flight Anxiety Scale, Probability Scale (measuring perceived probability of flying-negative events, general-negative and general positive events) and the Past-Negative, Future and Present-Hedonistic subscales of the Zimbardo Time Perspective Inventory (variables argued to predict mental travel forward and backward in time). The flying phobic group estimated the probability of flying negative and general negative events occurring as significantly higher than non-flying phobics. Past-Negative scores (positively) and Present-Hedonistic scores (negatively) predicted probability estimates of flying negative events. The Future Orientation subscale did not significantly predict probability estimates. This study is the first to demonstrate probability bias for threat-relevant outcomes in flying phobia. Results suggest that time perspective may influence perceived probability of threat-relevant outcomes but the nature of this relationship remains to be determined. PMID:27557054

Previous studies have demonstrated significant relationships among various cognitive variables such as negative cognition, self-efficacy, and social anxiety. Unfortunately, few studies focus on the role of cognition among youth, and researchers often fail to use domain-specific measures when examining cognitive variables. Therefore, the purpose of the present study was to examine domain-specific cognitive variables (i.e., socially oriented negative self-referent cognition and social self-efficacy) and their relationships to social anxiety in children and adolescents using structural equation modeling techniques. A community sample of children and adolescents (n=245; 55.9% female; 83.3% Caucasian, 9.4% African American, 2% Asian, 2% Hispanic, 2% "other," and 1.2% not reported) completed questionnaires assessing social cognition and social anxiety symptomology. Three latent variables were created to examine the constructs of socially oriented negative self-referent cognition (as measured by the SONAS scale), social self-efficacy (as measured by the SEQSS-C), and social anxiety (as measured by the SPAI-C and the Brief SA). The resulting measurement model of latent variables fit the data well. Additionally, consistent with the study hypothesis, results indicated that social self-efficacy likely mediates the relationship between socially oriented negative self-referent cognition and social anxiety, and socially oriented negative self-referent cognition yields significant direct and indirect effects on social anxiety. These findings indicate that socially oriented negative cognitions are associated with youth's beliefs about social abilities and the experience of social anxiety. Future directions for research and study limitations, including use of cross-sectional data, are discussed. © 2013.

Links between alcohol and other drug problems and maltreatment among adolescent girls: perceived discrimination, ethnic identity, and ethnic orientation as moderators.

Gray, Calonie M K; Montgomery, Marilyn J

2012-05-01

This study examined the links between maltreatment, posttraumatic stress symptoms, ethnicity-specific factors (i.e., perceived discrimination, ethnic identity, and ethnic orientation), and alcohol and/or other drug (AOD) problems among adolescent girls. These relations were examined using archived data from a community sample of 168 Black and Hispanic adolescent girls who participated in a school-based substance use intervention. The results revealed that maltreatment was linked to AOD problems, but only through its relation with posttraumatic stress symptoms; maltreatment was positively related to posttraumatic stress symptoms, which were positively related to AOD problems. Both perceived discrimination and ethnic orientation were significant moderators. Specifically, greater perceived discrimination was associated with an increased effect of maltreatment on posttraumatic stress symptoms. Ethnic orientation demonstrated protective properties in the relation between maltreatment and AOD problem severity, such that the effect of maltreatment on AOD problem severity was less for girls with average to high ethnic orientation compared to girls with low ethnic orientation. The findings of this study underscore the importance of developing interventions for Black and Hispanic girls that target maltreatment and AOD use concurrently and address ethnicity-specific factors.

Sexual orientation beliefs: their relationship to anti-gay attitudes and biological determinist arguments.

PubMed

Hegarty, P; Pratto, F

2001-01-01

Previous studies which have measured beliefs about sexual orientation with either a single item, or a one-dimensional scale are discussed. In the present study beliefs were observed to vary along two dimensions: the "immutability" of sexual orientation and the "fundamentality" of a categorization of persons as heterosexuals and homosexuals. While conceptually related, these two dimensions were empirically distinct on several counts. They were negatively correlated with each other. Condemning attitudes toward lesbians and gay men were correlated positively with fundamentality but negatively with immutability. Immutability, but not fundamentality, affected the assimilation of a biological determinist argument. The relationship between sexual orientation beliefs and anti-gay prejudice is discussed and suggestions for empirical studies of sexual orientation beliefs are presented.

Recent evidence in cultural and social psychology suggests Eastern cultures' emphasis on harmony and connection with others and Western cultures' emphasis on self-direction and autonomy. In Eastern society, relational harmony is closely linked to people's well-being. The impact of this cultural and social orientation on diabetes-related distress was investigated. Japanese and American patients with type 2 diabetes were surveyed by well-established questionnaire in Japan and in the United States, respectively. The association of personal values for interdependence, perceived emotional support, and the Problem Areas in Diabetes scale (PAID) were analyzed. A positive correlation between interdependence and PAID (r = 0.18; P = 0.025) and a negative correlation between perceived emotional support and PAID (r = - 0.24; P = 0.004) were observed after adjustments for other factors in Japanese data (n = 149), but not in American data (r = 0.00; P = 0.990, r = 0.02; P = 0.917, respectively, n = 50). In Japanese data, the three-factor structure of PAID (negative feelings about total life with diabetes, about living conditions with diabetes, and about treatment of diabetes) was identified, and interdependence showed significant positive correlations with the first and second factors and perceived emotional support showed significant negative correlations with all three factors of PAID. These results suggest that personal values for interdependence may be linked to the level of diabetes-related distress and that the distress may be relieved by perception of emotional support, especially in an interdependent cultural context.

I'm trying to heal...noise levels in a pediatric intensive care unit.

PubMed

Milette, Isabelle H; Carnevale, Franco A

2003-01-01

The literature demonstrates clearly that most intensive care units exceed the standard recommendations for noise levels in hospitals, and that high noise levels have negative impacts on patients and staff. The purpose of this study was to evaluate the level of noise in a PICU and compare it to the recommendations of international bodies. We outline recommendations to promote the awareness of this problem and suggest strategies to decrease the level of noise in a PICU. The orientations of these strategies are threefold: 1) architectural-acoustic design, 2) equipment design and, most importantly, 3) staff education.

Children's influence in the marital relationship.

Schermerhorn, Alice C; Cummings, E Mark; DeCarlo, Catherine A; Davies, Patrick T

2007-06-01

In a 3-wave longitudinal study, the authors tested hypotheses regarding children's influence on the marital relationship, examining relations between interparental discord and children's negative emotional reactivity, agentic behavior, dysregulated behavior, and psychosocial adjustment. Participants were 232 cohabiting mothers and fathers who completed questionnaires and a marital conflict resolution task. Consistent with theory, interparental discord related to children's negative emotional reactivity, which in turn related to children's agentic and dysregulated behavior. Agentic behavior related to decreases in interparental discord, whereas dysregulated behavior related to increases in discord and elevations in children's adjustment problems. Person-oriented analyses of agentic and dysregulated responses indicated distinct clusters of children linked with meaningful individual differences in marital and psychosocial functioning. Results are discussed in terms of possible mechanisms of child effects, such as increased parental awareness of children's distress potentially leading to reduced marital conflict.

2014-08-01

This study explored the use of object-oriented classification of remote sensing imagery in epidemiological studies of visceral leishmaniasis (VL) in urban areas. To obtain temperature and environmental information, an object-oriented classification approach was applied to Landsat 5 TM scenes from the city of Teresina, Piauí State, Brazil. For 1993-1996, VL incidence rates correlated positively with census tracts covered by dense vegetation, grass/pasture, and bare soil and negatively with areas covered by water and densely populated areas. In 2001-2006, positive correlations were found with dense vegetation, grass/pasture, bare soil, and densely populated areas and negative correlations with occupied urban areas with some vegetation. Land surface temperature correlated negatively with VL incidence in both periods. Object-oriented classification can be useful to characterize landscape features associated with VL in urban areas and to help identify risk areas in order to prioritize interventions.

Daytime incontinence and enuresis are common problems in otherwise healthy children, and negatively influence their social lives and self-esteem. Motivation for treatment is often a real clinical problem. Children's experiences of their incontinence treatments have not been previously described. The aim of this study was to describe children's experiences of the Voiding School intervention as a treatment for their incontinence. A qualitative, descriptive focus-group study with a purposive sample was conducted at a Finish university hospital in 2014. Children aged 6-12 years participated in the Voiding School at an outpatient clinic. The intervention included two 1-day group visits 2 months apart. The educational content was based on the International Children Continence Society's standards for urotherapy. The education was delivered with child-oriented teaching methods. At the end of the second visit, 19 children were interviewed in five groups. Data were analysed with inductive content analysis. The children described incontinence as an embarrassing problem, which they had to hide at any cost. They had experienced bullying and social isolation because of it. Normal outpatient visits emphasized adult-to-adult communication, which made the children feel like outsiders. The children perceived the Voiding School as a nice and child-oriented experience. Making new friends was especially important to younger boys who felt that the Voiding School day was too long and issue-oriented. In the Voiding School, videos and 'learning by doing' helped the children to understand the basis of given advice, and they were able to learn new habits, which gave them control over the incontinence; this helped them to become 'the boss of the bladder'. Sharing experiences and improvements in their incontinence with their peers supported the children's self-esteem and encouraged them to do new things, such as staying overnight with friends. These experiences helped them to acquire control over the problem (Summary Figure). According to the children's experiences, normal outpatient visits were only appointments for adults, and not very useful for children. In the Voiding School, they were respected as being the main person, and their views were listened to. The results underlined the importance of a child-oriented approach to patient education with regard to children, and provided encouragement to further develop the intervention. Child orientation, peer support, learning by doing, and understanding the cause and effect helped children to gain control over their bladders. Based on the children's experiences, this could be achieved by a voiding school. Copyright © 2017 Journal of Pediatric Urology Company. Published by Elsevier Ltd. All rights reserved.

Several studies have found that certain traits of impulsivity are associated with gambling disorder, and influence its severity. Furthermore, it has been suggested that some forms of gambling, particularly electronic gambling machines, are particularly widespread among pathological gamblers. In the present, exploratory study, we aim to clarify the role played by impulsivity in influencing the choice of specific gambling activities, by examining the relation between individual dimensions of impulsivity, and the choice of specific gambling activities in a clinical population. 100 consecutively admitted pathological gamblers at the National Problem Gambling Clinic in London (UK) in 2014 were administered the UPPS-P and BIS-11 impulsivity questionnaires, the Problem Gambling Severity Index, and underwent a structured interview concerning their gambling activities in the month and year prior to assessment. The correlation between individual gambling activities and impulsivity dimensions was analyzed both at a bivariate level, and using logistic regression. We found a significant correlation between Negative Urgency, Motor impulsivity and low-stakes machine gambling on multivariate analysis. Negative urgency (i.e. the tendency to act impulsively in response to negative affect), and Motor impulsivity (a tendency to rash action and restlessness) might be mediating factors in the choice of electronic gambling machines, particularly among patients whose gambling is escape-oriented. Structural and situational characteristics of gambling machines, particularly the widespread availability of low-stakes-rather than high-stakes-gaming machines, might concur to the choice of this form of gambling among individuals who present higher negative urgency and restlessness.

The affective structure of supportive parenting: depressive symptoms, immediate emotions, and child-oriented motivation.

This study investigated the maternal concerns and emotions that may regulate one form of sensitive parenting, support for children's immediate desires or intentions. While reviewing a videotape of interactions with their 1-year-olds, mothers who varied on depressive symptoms reported concerns and emotions they had during the interaction. Emotions reflected outcomes either to children (child-oriented concerns) or to mothers themselves (parent-oriented concerns). Child-oriented concerns were associated with fewer negative emotions and more supportive behavior. Supportive parenting was high among mothers who experienced high joy and worry and low anger, sadness, and guilt. However, relations depended on whether emotions were child or parent oriented: Supportive behavior occurred more when emotions were child oriented. In addition, as depressive symptoms increased, mothers reported fewer child-oriented concerns, fewer child-oriented positive emotions, and more parent-oriented negative emotions. They also displayed less supportive behavior. Findings suggest that support for children's immediate intentions may be regulated by parents' concerns, immediate emotions, and depressive symptoms.

Parenteau, Stacy C; Waters, Kristen; Cox, Brittany; Patterson, Tarsha; Carr, Richard

2017-01-02

An outgrowth of research has established a relationship between racial discrimination and alcohol use, as well as factors that moderate this association. The main objective of this study was to determine if religious orientation moderates the relationship between perceived racial discrimination and alcohol use. This study utilized a cross-sectional data collection strategy to examine the relationship among discrimination, religious orientation, and alcohol use among undergraduate students (N = 349) at a midsize southeastern university. Data was collected in 2014. Participants completed a demographic questionnaire, the General Ethnic Discrimination Scale, the Extrinsic/Intrinsic Religious Orientation Scale-Revised and the Drinking and Drug Habits Questionnaire. Analyses using hierarchical linear regression indicate a significant interaction effect (lifetime discrimination × extrinsic religious orientation) on problem drinking. Additional moderation analyses reveal a significant interaction effect between lifetime discrimination and the extrinsic-personal religious orientation on problem drinking. Results suggest that an extrinsic religious orientation, and particularly, an extrinsic-personal religious orientation, moderates the relationship between lifetime discrimination and problem drinking, suggesting that turning to religion for comfort and protection, rather than for the superficial purpose of seeing/making friends at church, may buffer against the deleterious effects of discrimination-specifically, engaging in problem drinking to cope with the stress of discrimination. Limitations, directions for future research, and clinical implications are discussed.

2017-01-01

BACKGROUND: Cancer and its treatments have been shown to have a negative psychological effect on many cancer patients. One of these effects is often described as body image disturbance. Due to the limited number of studies in this area, this study was performed to assess body image in cancer patients and its association with clinical variables. MATERIALS AND METHODS: This was a descriptive and correlational research that was designed in Sayyed-Al-Shohda Hospital affiliated to Isfahan University of Medical Sciences, Iran in 2013. Two hundred and ten adult patients who had been suffering from cancer were selected and completed the personal/demographic/illness questionnaire and the multi-dimensional body-self relations questionnaire that contained 64-items with appearance orientation, appearance evaluation, fitness evaluation, fitness orientation, health evaluation, health orientation, illness orientation, body areas satisfaction, self-classified weight and overweight preoccupation sub-scales. Data were analyzed by ANOVA and Pearson correlation with a significance level of P < 0.05. RESULTS: The mean (standard deviation (scores of body image in cancer patients was 184.40 (43.68) indicating that 58.3% of them had negative body image. In addition, most of patients had negative health evaluation (60.2%), negative appearance evaluation (63%), negative illness orientation (61%), and negative fitness orientation (56%). Furthermore, there were no significant correlations between type of cancer (P = 0.5, f = 0.3), kind of treatment (P = 0.8, f = 5.2) and duration of illness with body image (P = 0.6, r = −0.2). CONCLUSION: In this study most of the cancer patients had body image disturbances. Also, body image in this group wasn’t associated with the type of cancer, kind of treatment and duration of illness. Totally, these results underscore the importance of assessing and treating body image disturbance in cancer patients. PMID:29114549

Tolerating the “doubting Thomas”: how centrality of religious beliefs vs. practices influences prejudice against atheists

PubMed Central

Hughes, Jeffrey; Grossmann, Igor; Cohen, Adam B.

2015-01-01

Past research has found a robust effect of prejudice against atheists in largely Christian-dominated (belief-oriented) samples. We propose that religious centrality of beliefs vs. practices influences attitudes toward atheists, such that religious groups emphasizing beliefs perceive non-believers more negatively than believers, while groups emphasizing practices perceive non-practicing individuals more negatively than practicing individuals. Studies 1–2, in surveys of 41 countries, found that Muslims and Protestants (belief-oriented) had more negative attitudes toward atheists than did Jews and Hindus (practice-oriented). Study 3 experimentally manipulated a target individual's beliefs and practices. Protestants had more negative attitudes toward a non-believer (vs. a believer), whereas Jews had more negative attitudes toward a non-practicing individual (vs. a practicing individual, particularly when they had a Jewish background). This research has implications for the psychology of religion, anti-atheist prejudice, and cross-cultural attitudes regarding where dissent in beliefs or practices may be tolerated or censured within religious groups.

2001-06-01

To describe the criterion validity of nursing home staff's assessment of organic disorder compared with ICD-10 criteria, and to identify determinants of staff assessment of organic disorder. Two hundred and eighty-eight residents were diagnosed using the GMS-AGECAT. Nursing staff members were interviewed about the residents' activities of Daily Living, behavioural problems, orientation in surroundings and communication skills, and asked if the resident had an organic disorder. Multiple logistic regression was used to select the items that most strongly determined staff assessment of organic disorder. Sixty-two per cent of the residents were diagnosed by GMS-AGECAT as having organic disorder, 78% of these were correctly identified by the staff. Whether analysed among residents with or without organic disorder, or in the total group of residents, the staff assessment of the presence of organic disorder depended on a limited set of behavioural characteristics of the resident, namely 'going to the toilet in inappropriate places', 'saying things that do not make sense' and impairment in orientation. Staff comprehension of organic disorder resulted in over- as well as under-labelling of residents, a tendency that will affect communication with medical personnel and may lead to inadequate or wrong medical treatment and to negative performance as well as negative role expectations in everyday life in nursing homes.

Social inequality and smoking in young Swiss men: intergenerational transmission of cultural capital and health orientation.

Smoking is related to income and education and contributes to social inequality in morbidity and mortality. Socialisation theories focus on one's family of origin as regards acquisition of norms, attitudes and behaviours. Aim of this study is to assess associations of daily smoking with health orientation and academic track in young Swiss men. Further, to assess associations of health orientation and academic track with family healthy lifestyle, parents' cultural capital, and parents' economic capital. Cross-sectional data were collected during recruitment for compulsory military service in Switzerland during 2010 and 2011. A structural equation model was fitted to a sample of 18- to 25-year-old Swiss men (N = 10,546). Smoking in young adults was negatively associated with academic track and health orientation. Smoking was negatively associated with parents' cultural capital through academic track. Smoking was negatively associated with health orientation which in turn was positively associated with a healthy lifestyle in the family of origin. Results suggest two different mechanisms of intergenerational transmissions: first, the family transmission path of health-related dispositions, and secondly, the structural transmission path of educational inequality.

Are the religious suspicious of science? Investigating religiosity, religious context, and orientations towards science.

Are the religious suspicious of science? Drawing on data from 52 nations in the World Values Survey (wave 6) ( N = 58,474), I utilize multilevel models to examine the relationship between religiosity, religious context, and five different orientations towards science: confidence in science, trust in scientific authority under conditions of conflict with religion, faith in science, views on the moral effects of science, and interest in scientific knowledge. Results show that while religiosity is on average negatively associated with the five outcomes, the relationship between religiosity and orientations towards science varies by country such that religiosity is sometimes positively associated with the different outcomes. Religiosity is only consistently negatively associated with trust in scientific authority in all countries and with all orientations towards science in western countries. Finally, differences in orientations towards science also exist across country religious contexts, with countries dominated by the unaffiliated having more positive orientations towards science.

Indecision and avoidant procrastination: the role of morningness-eveningness and time perspective in chronic delay lifestyles.

PubMed

Díaz-Morales, Juan Francisco; Ferrari, Joseph R; Cohen, Joseph R

2008-07-01

The authors examined how time orientation and morningness-eveningness relate to 2 forms of procrastination: indecision and avoidant forms. Participants were 509 adults (M age = 49.78 years, SD = 6.14) who completed measures of time orientation, morningness-eveningness, decisional procrastination (i.e., indecision), and avoidant procrastination. Results showed that morningness was negatively related to avoidant procrastination but not decisional procrastination. Overall, the results indicated different temporal profiles for indecision and avoidant procrastinations. Avoidant procrastination related to low future time orientation and low morningness, whereas indecision related to both (a) high negative and high positive past orientations and (b) low present-hedonistic and low future time orientations. The authors inferred that distinct forms of procrastination seem different on the basis of dimensions of time.

An iterated local search algorithm for the team orienteering problem with variable profits

Gunawan, Aldy; Ng, Kien Ming; Kendall, Graham; Lai, Junhan

2018-07-01

The orienteering problem (OP) is a routing problem that has numerous applications in various domains such as logistics and tourism. The objective is to determine a subset of vertices to visit for a vehicle so that the total collected score is maximized and a given time budget is not exceeded. The extensive application of the OP has led to many different variants, including the team orienteering problem (TOP) and the team orienteering problem with time windows. The TOP extends the OP by considering multiple vehicles. In this article, the team orienteering problem with variable profits (TOPVP) is studied. The main characteristic of the TOPVP is that the amount of score collected from a visited vertex depends on the duration of stay on that vertex. A mathematical programming model for the TOPVP is first presented and an algorithm based on iterated local search (ILS) that is able to solve modified benchmark instances is then proposed. It is concluded that ILS produces solutions which are comparable to those obtained by the commercial solver CPLEX for smaller instances. For the larger instances, ILS obtains good-quality solutions that have significantly better objective value than those found by CPLEX under reasonable computational times.

García-Ael, Cristina; Cuadrado, Isabel; Molero, Fernando

2013-01-01

From the perspective of the Think manager--think male, this study was conducted to examine the type of leadership role depending on gender in a sample of 158 Spanish adolescents -according to three types of leaders: "male middle leader", "female middle leader" and "middle leader in general". The kind of emotional expression (positive and negative) evoked by their leadership behaviors (task- and relationship- oriented) was also analyzed. Lastly, whether adolescents' sexist beliefs affected the attribution of traits and the emotional expression towards these leaders was examined. Results showed that task-oriented traits were more characteristic of the leadership role than relationship-oriented traits. Adolescents expressed more positive emotions towards a task-oriented leader and towards a leader behaving in ways associated with both task- and relationship- oriented styles, but only for men. Finally, hostile sexism predicted fewer task-oriented traits to female leaders, more negative affect towards task-oriented male leaders and towards counter-stereotypic leaders. These results were moderated by the sex of adolescents.

The main purpose of this study was to investigate the agency problem presented by the global budget system followed by hospitals in Taiwan. In this study, we examine empirically the interaction between the principal: Bureau of National Health Insurance (BNHI) and agency: medical service providers (hospitals); we also describe actual medical service provider and hospital governance conditions from a agency theory perspective. This study identified a positive correlation between aversion to agency hazard (self-interest behavior, asymmetric information, and risk hedging) and agency problem risks (disregard of medical ethics, pursuit of extra-contract profit, disregard of professionalism, and cost orientation). Agency costs refer to BNHI auditing and monitoring expenditures used to prevent hospitals from deviating from NHI policy goals. This study also found agency costs negatively moderate the relationship between agency hazards and agency problems The main contribution of this study is its use of agency theory to clarify agency problems and several potential factors caused by the NHI system. This study also contributes to the field of health policy study by clarifying the nature and importance of agency problems in the health care sector. Copyright © 2014 Elsevier Ireland Ltd.

Perception of second- and third-order orientation signals and their interactions

PubMed Central

Victor, Jonathan D.; Thengone, Daniel J.; Conte, Mary M.

2013-01-01

Orientation signals, which are crucial to many aspects of visual function, are more complex and varied in the natural world than in the stimuli typically used for laboratory investigation. Gratings and lines have a single orientation, but in natural stimuli, local features have multiple orientations, and multiple orientations can occur even at the same location. Moreover, orientation cues can arise not only from pairwise spatial correlations, but from higher-order ones as well. To investigate these orientation cues and how they interact, we examined segmentation performance for visual textures in which the strengths of different kinds of orientation cues were varied independently, while controlling potential confounds such as differences in luminance statistics. Second-order cues (the kind present in gratings) at different orientations are largely processed independently: There is no cancellation of positive and negative signals at orientations that differ by 45°. Third-order orientation cues are readily detected and interact only minimally with second-order cues. However, they combine across orientations in a different way: Positive and negative signals largely cancel if the orientations differ by 90°. Two additional elements are superimposed on this picture. First, corners play a special role. When second-order orientation cues combine to produce corners, they provide a stronger signal for texture segregation than can be accounted for by their individual effects.

Students Relationships and Teacher's Authority as Axiological, Ethical, Pedagogical, Social and Psychological Problems

NASA Astrophysics Data System (ADS)

Sawicki, Silvester

2011-01-01

The paper is focused on the research into the problems of education regarding the relations between students (bullying, competiveness and cooperation) and the decreasing teacher's authority in schools and society. We found that relations between pupils and students of elementary and secondary schools show several negative tendencies including harming each other, reduced rate of mutual sensitivity and preference of rivality to cooperation. Authority of teachers is permanently decreasing not only with pupils and students, but with parents and society, too. Society, parents and students much less value study results and wisdom, and these issues consequently influence the decreasing teacher's status. On the other hand, this behavior leads to decreasing the interest in semantic learning. The roots of these problems can be found in the postmodern crisis of Western culture, associated with severe deficiencies of the political system and market economy as well as one-sided rational orientation of Western society at the expense of the spiritual needs of man.

Problem solving, contention, and struggle: how siblings resolve a conflict of interests.

PubMed

Ram, A; Ross, H S

2001-01-01

In a laboratory setting, 48 sibling dyads age 4 and 6 or 6 and 8 years negotiated the division of six toys. Findings revealed that, in general, children reached divisions while using a preponderance of constructive problem-solving strategies, rather than contentious tactics. The degree of conflict of interests and the quality of sibling relationships predicted the children's use of problem-solving and contentious negotiation strategies, and was related to the types of resolutions achieved. Dyads experiencing low conflict of interests resolved their differences quickly. High conflict of interests coupled with positive relationships and constructive negotiation resulted in longer negotiations and creative, agreeable resolutions. High conflict of interests coupled with more negative relationships and destructive negotiations resulted in children's failures to reach agreement. Developmental differences indicated that older siblings within the pairs took the lead in negotiation, and benefited slightly more from the divisions. Furthermore, children in older dyads were more sophisticated and other oriented in their negotiations.

2014-01-01

Purpose A multidimensional intervention integrating alexithymia, negative affect, and type of coping strategy is needed for the effective treatment of somatoform disorder; however, few studies have applied this approach to the three different dimensions of alexithymia in patients with somatoform disorder. The purpose of this study was to determine the relationship between type of coping strategy and three different dimensions of alexithymia expressed in patients. Patients and methods A total of 196 patients with somatoform disorder completed the 20-item Toronto Alexithymia Scale, the Zung Self-Rating Depression Scale, the Spielberger State–Trait Anxiety Inventory, the Somatosensory Amplification Scale, and the Lazarus Stress Coping Inventory. The relationships between alexithymia (Toronto Alexithymia Scale – 20 score and subscales), demographic variables, and psychological inventory scores were analyzed using Pearson’s correlation coefficients and stepwise multiple regression analysis. Results The mean Toronto Alexithymia Scale – 20 total score (56.1±10.57) was positively correlated with the number of physical symptoms as well as with psychopathology scores (Self-Rating Depression Scale, State–Trait Anxiety Inventory trait, state, and Somatosensory Amplification Scale), but negatively correlated with planful problem solving, confrontive coping, seeking social support, and positive reappraisal coping scores. With respect to coping strategy, multiple regression analyses revealed that “difficulty in identifying feelings” was positively associated with an escape–avoidance strategy, “difficulty in describing feelings” was negatively associated with a seeking social support strategy, and “externally oriented thinking” was negatively associated with a confrontive coping strategy. Conclusion Alexithymia was strongly associated with the number of somatic symptoms and negative affect. Patients with high “difficulty in describing feelings” tend to rely less on seeking social support, and patients with high “externally oriented thinking” tend to rely less on confrontive coping strategies. The coping skills intervention implemented should differ across individuals and should be based on the alexithymia dimension of each patient. PMID:24403835

Migrants suffer from various health problems including psychological stress. This study is the first to use the Community Oriented Primary Care methodology to address a health problem among Arab migrant women in Germany. In partnership with the Muslim Women's Educational Center in Cologne, we defined a community, identified an important health problem through focus groups, key informant interviews and a community discussion group, and studied psychological stress in a sample of Arab migrant women (N = 116) using a questionnaire that included the Symptom Checklist-90-Revised (SCL-90-R) instrument. Almost 90% of participating women were psychologically stressed. About half of the women cited "feeling lonely" as a main source of stress and another third cited religious, moral and personal factors as sources of stress. While the majority of women reacted to stressful situations with crying, 23% coped by talking to others and 20% through worship. Higher stress scores were associated with older age, lower level of education, having more children, coming from a North African rather than Middle Eastern or European country, having lived in Germany for <15 years, having had a disease since migrating to Germany, being ill at the time of the study, and feeling negatively about being a migrant. To date, this study provides the most comprehensive study of psychological distress among Arab migrants in Germany, and provides important information for future studies and interventions.

Parallel tempering Monte Carlo simulations of lysozyme orientation on charged surfaces

NASA Astrophysics Data System (ADS)

Xie, Yun; Zhou, Jian; Jiang, Shaoyi

2010-02-01

In this work, the parallel tempering Monte Carlo (PTMC) algorithm is applied to accurately and efficiently identify the global-minimum-energy orientation of a protein adsorbed on a surface in a single simulation. When applying the PTMC method to simulate lysozyme orientation on charged surfaces, it is found that lysozyme could easily be adsorbed on negatively charged surfaces with "side-on" and "back-on" orientations. When driven by dominant electrostatic interactions, lysozyme tends to be adsorbed on negatively charged surfaces with the side-on orientation for which the active site of lysozyme faces sideways. The side-on orientation agrees well with the experimental results where the adsorbed orientation of lysozyme is determined by electrostatic interactions. As the contribution from van der Waals interactions gradually dominates, the back-on orientation becomes the preferred one. For this orientation, the active site of lysozyme faces outward, which conforms to the experimental results where the orientation of adsorbed lysozyme is co-determined by electrostatic interactions and van der Waals interactions. It is also found that despite of its net positive charge, lysozyme could be adsorbed on positively charged surfaces with both "end-on" and back-on orientations owing to the nonuniform charge distribution over lysozyme surface and the screening effect from ions in solution. The PTMC simulation method provides a way to determine the preferred orientation of proteins on surfaces for biosensor and biomaterial applications.

The curvilinear effects of sexual orientation on young adult substance use.

2017-03-01

Alcohol, tobacco, and marijuana are commonly used by adolescents and linked with harmful health-related outcomes (e.g. injury, dependence). Moreover, heavy episodic (binge) drinking predicts more severe consequences. When examined by sexual orientation, highest rates of substance use have been found among bisexual individuals, with lower use at either end of the spectrum. When examined also by sex, this curvilinear trend is maintained among women but not men. These substance use patterns were identified using group differences (i.e. heterosexual vs. bisexual vs. homosexual). However, evidence suggests that sexual orientation is a continuous, not categorical, variable. This study examined the hypotheses that sexual orientation and commonly used substances (heavy episodic drinking, tobacco, marijuana) would have a quadratic relation among women, but not among men. Six negative binomial regressions tested study hypotheses using data from 7372 participants. Results indicated that sexual orientation had a quadratic relation with heavy episodic drinking, tobacco use, and marijuana use among women, as hypothesized. Additionally, a quadratic relation was found between marijuana use and sexual orientation among men. These findings indicate that women identifying as having mixed sexual orientation are at higher risk than women at either end of the sexual orientation continuum for substance use and related negative outcomes. For men, this is only true for marijuana use and resultant negative consequences. This observed increased use may relate to coping with increased stressors, which has been linked to more problematic use. By better understanding LBG identities and behaviors, clinicians and researchers will be more adept at identifying risk factors and better understanding the nuances across the sexual orientation spectrum.

Merrill, J M; Lorimor, R J; Thornby, J I; Vallbona, C

1998-01-01

To gain a better understanding of senior medical students who perceive high-technology medicine as the desirable form of medical practice, we developed and evaluated a structural equation model. Intolerance to clinical uncertainty, Machiavellianism, and authoritarianism characterized students who scored higher on reliance on high-technology medicine. High scorers also tended to have a negative orientation toward patients' psychological problems and were unlikely to choose careers in primary care medicine. Students who perceive high technology as a panacea in clinical medicine share personal traits and attitudes toward patients that are not conducive to achieving the national goal of a 50:50 ratio between primary and non-primary care physicians.

Effects of Achievement Goals on Challenge Seeking and Feedback Processing: Behavioral and fMRI Evidence

PubMed Central

Lee, Woogul; Kim, Sung-il

2014-01-01

We conducted behavioral and functional magnetic resonance imaging (fMRI) research to investigate the effects of two types of achievement goals—mastery goals and performance-approach goals— on challenge seeking and feedback processing. The results of the behavioral experiment indicated that mastery goals were associated with a tendency to seek challenge, both before and after experiencing difficulty during task performance, whereas performance-approach goals were related to a tendency to avoid challenge after encountering difficulty during task performance. The fMRI experiment uncovered a significant decrease in ventral striatal activity when participants received negative feedback for any task type and both forms of achievement goals. During the processing of negative feedback for the rule-finding task, performance-approach-oriented participants showed a substantial reduction in activity in the dorsolateral prefrontal cortex (DLPFC) and the frontopolar cortex, whereas mastery-oriented participants showed little change. These results suggest that performance-approach-oriented participants are less likely to either recruit control processes in response to negative feedback or focus on task-relevant information provided alongside the negative feedback. In contrast, mastery-oriented participants are more likely to modulate aversive valuations to negative feedback and focus on the constructive elements of feedback in order to attain their task goals. We conclude that performance-approach goals lead to a reluctant stance towards difficulty, while mastery goals encourage a proactive stance. PMID:25251396

Determinants of a successful problem list to support the implementation of the problem-oriented medical record according to recent literature.

PubMed

Simons, Sereh M J; Cillessen, Felix H J M; Hazelzet, Jan A

2016-08-02

A problem-oriented approach is one of the possibilities to organize a medical record. The problem-oriented medical record (POMR) - a structured organization of patient information per presented medical problem- was introduced at the end of the sixties by Dr. Lawrence Weed to aid dealing with the multiplicity of patient problems. The problem list as a precondition is the centerpiece of the problem-oriented medical record (POMR) also called problem-oriented record (POR). Prior to the digital era, paper records presented a flat list of medical problems to the healthcare professional without the features that are possible with current technology. In modern EHRs a POMR based on a structured problem list can be used for clinical decision support, registries, order management, population health, and potentially other innovative functionality in the future, thereby providing a new incentive to the implementation and use of the POMR. On both 12 May 2014 and 1 June 2015 a systematic literature search was conducted. From the retrieved articles statements regarding the POMR and related to successful or non-successful implementation, were categorized. Generic determinants were extracted from these statements. In this research 38 articles were included. The literature analysis led to 12 generic determinants: clinical practice/reasoning, complete and accurate problem list, data structure/content, efficiency, functionality, interoperability, multi-disciplinary, overview of patient information, quality of care, system support, training of staff, and usability. Two main subjects can be distinguished in the determinants: the system that the problem list and POMR is integrated in and the organization using that system. The combination of the two requires a sociotechnical approach and both are equally important for successful implementation of a POMR. All the determinants have to be taken into account, but the weight given to each of the determinants depends on the organizationusing the problem list or POMR.

Autobiographical memory development from an attachment perspective: the special role of negative events.

PubMed

Chae, Yoojin; Goodman, Gail S; Edelstein, Robin S

2011-01-01

The authors propose a novel model of autobiographical memory development that features the fundamental role of attachment orientations and negative life events. In the model, it is proposed that early autobiographical memory derives in part from the need to express and remember negative experiences, a need that has adaptive value, and that attachment orientations create individual differences in children's recollections of negative experiences. Specifically, the role of attachment in the processing of negative information is discussed in regard to the mnemonic stages of encoding, storage, and retrieval. This model sheds light on several areas of contradictory data in the memory development literature, such as concerning earliest memories and children's and adults' memory/suggestibility for stressful events.

A device-oriented optimizer for solving ground state problems on an approximate quantum computer, Part II: Experiments for interacting spin and molecular systems

Hybrid quantum-classical algorithms can be used to find variational solutions to generic quantum problems. Here, we present an experimental implementation of a device-oriented optimizer that uses superconducting quantum hardware. The experiment relies on feedback between the quantum device and classical optimization software which is robust to measurement noise. Our device-oriented approach uses naturally available interactions for the preparation of trial states. We demonstrate the application of this technique for solving interacting spin and molecular structure problems.

Overcoming beneficiary race as an impediment to charitable donations: social dominance orientation, the experience of moral elevation, and donation behavior.

PubMed

Freeman, Dan; Aquino, Karl; McFerran, Brent

2009-01-01

Three studies examined the relationship between social dominance orientation (SDO), the experience of moral elevation, and Whites' donations to charitable organizations. Study 1 used video clips depicting acts of moral excellence to elicit a state of moral elevation (a distinctive feeling of warmth and expansion, which is accompanied by admiration, affection, and even love for people whose exemplary moral behavior is being observed). Results show that moral elevation increased participants' willingness to donate to a Black-oriented charity and attenuated the negative effect of the group-based dominance (GBD) component of SDO on donation behavior. Studies 2 and 3 replicate and extend these findings by using a written story to elicit a state of moral elevation and examining actual donations to a Black-oriented charity. Results show that moral elevation increased donations to the Black-oriented charity and neutralized the negative influence of GBD.

When sex is more than just sex: attachment orientations, sexual experience, and relationship quality.

2006-11-01

The authors explored the contribution of individual differences in attachment orientations to the experience of sexual intercourse and its association with relationship quality. In Study 1, 500 participants completed self-report scales of attachment orientations and sexual experience. The findings indicated that whereas attachment anxiety was associated with an ambivalent construal of sexual experience, attachment avoidance was associated with more aversive sexual feelings and cognitions. In Study 2, 41 couples reported on their attachment orientations and provided daily diary measures of sexual experiences and relationship interactions for a period of 42 days. Results showed that attachment anxiety amplified the effects of positive and negative sexual experiences on relationship interactions. In contrast, attachment avoidance inhibited the positive relational effect of having sex and the detrimental relational effects of negative sexual interactions. The authors discuss the possibility that attachment orientations are associated with different sex-related strategies and goals within romantic relationships.

"So Happy I Could Shout!" and "So Happy I Could Cry!" Dimorphous expressions represent and communicate motivational aspects of positive emotions.

PubMed

Aragón, Oriana R; Bargh, John A

2018-03-01

Happiness can be expressed through smiles. Happiness can also be expressed through physical displays that without context, would appear to be sadness (tears, downward turned mouths, and crumpled body postures) and anger (clenched jaws, snarled lips, furrowed brows, and pumped fists). These seemingly incongruent displays of happiness, termed dimorphous expressions, we propose, represent and communicate expressers' motivational orientations. When participants reported their own aggressive expressions in positive or negative contexts, their expressions represented positive or negative emotional experiences respectively, imbued with appetitive orientations (feelings of wanting to go). In contrast, reported sad expressions, in positive or negative contexts, represented positive and negative emotional experiences respectively, imbued with consummatory orientations (feelings of wanting to pause). In six additional experiments, participant observers interpreted that aggression displayed in positive contexts signalled happy-appetitive states, and sadness displayed in positive contexts signalled happy-consummatory states. Implications for the production and interpretation of emotion expressions are discussed.

A Longitudinal Analysis of the Indirect Effect of Violence Exposure on Future Orientation Through Perceived Stress and the Buffering Effect of Family Participation.

PubMed

Schmidt, Carissa J; Zimmerman, Marc A; Stoddard, Sarah A

2018-06-07

Exposure to violence (ETV) during adolescence has been associated with negative effects in later life, and may negatively affect an individual's future orientation. Future orientation has important health implications and warrants being studied. Yet, few researchers have examined how ETV affects an individual's future orientation as a young adult. The purpose of this study was to examine the indirect effect of ETV during adolescence on future orientation as a young adult through perceived stress. We also tested the moderating effect of family participation on the relationship between perceived stress and future orientation. Longitudinal data from a sample of 316 African American participants (42.10% male and 57.90% female, Mage = 14.76 at Wave 1) from low socioeconomic backgrounds recruited from a Midwestern school district were used in the analysis. Multigroup structural equation modeling (SEM) was used to test our hypotheses. Our findings indicated that greater ETV during adolescence is associated with higher levels of perceived stress and, in turn, a more negative outlook on one's future as a young adult. This indirect effect occurred for individuals with lower family participation, but was not evident for individuals with greater family participation. These findings provide important implications for youth development interventions. © Society for Community Research and Action 2018.

The ability of positive and negative facial signals to influence attention orienting is crucial to social functioning. Given the dramatic developmental change in neural architecture supporting social function, positive and negative facial cues may influence attention orienting differently in relatively young or old individuals. However, virtually no research examines such age-related differences in the neural circuitry supporting attention orienting to emotional faces. We examined age-related correlations in attention-orienting biases to positive and negative face emotions in a healthy sample (N=37; 9-40 years old) using functional magnetic resonance imaging and a dot-probe task. The dot-probe task in an fMRI setting yields both behavioral and neural indices of attention biases towards or away from an emotional cue (happy or angry face). In the full sample, angry-face attention bias scores did not correlate with age, and age did not correlate with brain activation to angry faces. However, age did positively correlate with attention bias towards happy faces; age also negatively correlated with left cuneus and left caudate activation to a happy-bias fMRI contrast. Secondary analyses suggested age-related changes in attention bias to happy faces. The tendency in younger children to direct attention away from happy faces (relative to neutral faces) was diminished in the older age groups, in tandem with increasing neural deactivation. Implications for future work on developmental changes in attention-emotion processing are discussed. PMID:19631626

Stress and coping in Singaporean nurses: a literature review.

PubMed

Lim, Joanne; Bogossian, Fiona; Ahern, Kathy

2010-06-01

Stress is ubiquitous in the nursing profession and is also prevalent in Asian countries, particularly the "four tigers of Asia": Singapore, Hong Kong, Taiwan, and South Korea. Based on the theoretical framework of Lazarus and Folkman (1984), the present review of the nursing literature aims to identify sources and effects of stress in Singaporean nurses and the coping strategies they use. Nurses reported major stressors including shortage of staff, high work demands and conflict at work. Common coping strategies included problem orientation, social support and relaxation techniques. Several studies reported nurses' intent to leave the profession. Recommendations to minimize the impact of stress include in-service programs to facilitate a problem-solving approach to resolving work-related issues such as conflict. Relaxation therapy and debriefing sessions may also help in reducing negative effects of work stressors. Finally, nurses' emotional coping can be enhanced by strengthening sources of social support, particularly from family.

Experiential Avoidance Mediates the Association between Emotion Regulation Abilities and Loneliness.

2016-01-01

Experiential avoidance (EA) involves the unwillingness to remain in contact with aversive experiences such as painful feelings, thoughts, and emotions. EA is often associated with the development and maintenance of emotional problems. Since loneliness is characterized by negative emotions such as sadness and pessimism, which is often linked to emotional problems, this study aims to test the mediating effects of EA on the relationship between emotion regulation abilities (ERA) and loneliness in a sample of Chinese adults. Five hundred undergraduates completed questionnaires measuring EA (Acceptance and Action Questionnaire; AAQ-Ⅱ), ERA (Failure-relate action orientation; Action Control Scale, ACS-90) and loneliness (UCLA Loneliness Scale). Structural equation modeling showed that EA fully-mediated the relationship between ERA and loneliness. The findings suggest EA is a key mechanism in explaining why people with high ERA are prone to feeling lower levels of loneliness. In particular, these findings have important implications for designing effective psychological interventions for loneliness.

2012-08-24

We describe a soft matter system of self-organized oblate micelles and plasmonic gold nanorods that exhibit a negative orientational order parameter. Because of anisotropic surface anchoring interactions, colloidal gold nanorods tend to align perpendicular to the director describing the average orientation of normals to the discoidal micelles. Helicoidal structures of highly concentrated nanorods with a negative order parameter are realized by adding a chiral additive and are further controlled by means of confinement and mechanical stress. Polarization-sensitive absorption, scattering, and two-photon luminescence are used to characterize orientations and spatial distributions of nanorods. Self-alignment and effective-medium optical properties of these hybrid inorganic-organic complex fluids match predictions of a simple model based on anisotropic surface anchoring interactions of nanorods with the structured host medium.

The association of daily hassles and uplifts with family and life satisfaction: does cultural orientation make a difference?

2008-03-01

The study examined similarities and differences between people having individualist and collectivist cultural orientations in terms of what they perceive as stressful and uplifting experiences in their daily lives, and the relation between daily experiences and family and life satisfaction. Data were collected from two representative community samples (697 Jews and 303 Arabs). Each sample was grouped into individualist and collectivist cultural orientations. The two cultural orientation groups differed with respect to the appraisal of positive and negative daily experiences. A structural equation modeling (SEM) multi-group analysis indicated a similar factor structure for hassles and uplifts in both groups. However, the two groups differed in the effects of positive and negative daily occurrences on family and life satisfaction.

Lindfors, Kirsi; Meretoja, Riitta; Kaunonen, Marja; Paavilainen, Eija

2018-04-01

To identify existing orientation patterns and to find elements that may enhance or impede successful orientation of newly graduated nurses. Preceptors have first-hand information concerning orientation and their opinions should not be forgotten when organisations develop their orientation processes. An open-ended questionnaire was undertaken to collect data from preceptors (n = 172) about the current orientation patterns. Data were analysed by using deductive content analysis and by quantifying the phrases. Communal commitment to the orientation process, strong professional orientation know-how and supportive leadership were the enhancing elements of successful orientation. Complex interpersonal relationship problems during orientation, inadequate orientation resources and the organisation's structural and functional problems were the impeding elements of successful orientation. With the elements of successful orientation we ensure a supportive transition to practice for newly graduate nurses and possibilities to focus on good orientation practices for preceptors. Nurse leaders play an important part in ensuring newly graduated nurses have a safe nursing career starting point and, for preceptors, opportunities to provide orientation that is as good as possible. Supportive leadership, sufficient resources and good interpersonal relationships should be the leading principles during newly graduated nurses' orientation period. © 2017 John Wiley & Sons Ltd.

[Action-oriented versus state-oriented reactions to experimenter-induced failures].

PubMed

Brunstein, J C

1989-01-01

The present study assessed different effects of action-oriented versus state-oriented styles of coping with failure on achievement-related performance and cognition. In a learned helplessness experiment, students were exposed to an academic failure situation and were then tested on a series of problem-solving tasks, either immediately after the pretreatment or after a delay of 24 hours. Performance and cognitive concomitants were measured during both experimental periods. Results demonstrated that action orientation was associated with self-immunizing cognitions during helplessness training. Action-oriented participants improved their performance level even after repeated failure feedbacks. Moreover, action-oriented students assigned to the delayed test condition responded with increased striving for success and showed performance increments, even in comparison with control subjects. In contrast, state-oriented participants developed symptoms of helplessness and showed impaired performance during failure inductions. In later tests on problem-solving tasks, state-oriented groups responded with increased fear of failure. Independent of immediate or delayed test conditions, they soon lapsed into new performance decrements.

Love and sex are fundamental needs of most people, yet little research has examined such aspects of life in relation to personality pathologies. We examined the associations between pathological personality traits (i.e., negative affectivity, disinhibition, antagonism, psychoticism, and detachment) and sociosexuality (i.e., short-term mating orientation, long-term mating orientation, and sexual behavior) among 702 university students. In addition, we examined the mediating role of life history speed and tested whether sex moderated the associations that these pathological personality traits had with sociosexuality. Detachment, antagonism, disinhibition, and psychoticism had positive associations with short-term mating interests and negative associations with long-term mating interests. Life history speed mediated the associations that detachment and disinhibition had with short-term mating orientation and long-term mating orientation. Although sex did moderate the association that negative affectivity had with previous sexual behavior, we found no evidence that these mediational processes differed between men and women. Results are discussed in terms of the way personality traits shape the sociosexuality of men and women using a life history paradigm.

The core components of the planar cell polarity (PCP) signaling system, including both transmembrane and peripheral membrane associated proteins, form asymmetric complexes that bridge apical intercellular junctions. While these can assemble in either orientation, coordinated cell polarization requires the enrichment of complexes of a given orientation at specific junctions. This might occur by both positive and negative feedback between oppositely oriented complexes, and requires the peripheral membrane associated PCP components. However, the molecular mechanisms underlying feedback are not understood. We find that the E3 ubiquitin ligase complex Cullin1(Cul1)/SkpA/Supernumerary limbs(Slimb) regulates the stability of one of the peripheral membrane components, Prickle (Pk). Excess Pk disrupts PCP feedback and prevents asymmetry. We show that Pk participates in negative feedback by mediating internalization of PCP complexes containing the transmembrane components Van Gogh (Vang) and Flamingo (Fmi), and that internalization is activated by oppositely oriented complexes within clusters. Pk also participates in positive feedback through an unknown mechanism promoting clustering. Our results therefore identify a molecular mechanism underlying generation of asymmetry in PCP signaling.

Drug-addicted patients exhibit various personality disorders that interfere with their adaptation to society, as well as their ability to participate in the rehabilitation process. The Latvian Rehabilitation Programme for drug addicts includes social problem-solving training to help patients reintegrate into society. However, the role of personality disorders has not been investigated in relation to this process. The aim of the study is to assess whether personality disorders predict changes in dimensions of social problem-solving after 6 months of rehabilitation for drug-addicted patients. The sample of this study consists of 31 drug-addicted patients from the Latvian rehabilitation centres aged 21-35 (females 21%, males 79%). Two inventories are used: the Social Problem-Solving Inventory--Revised (SPSI-R) and Millon(TM) Clinical Multiaxial Inventory--III (MCMI-III) adapted into Russian. Results of the study indicated that some MCMI-III personality disorders (Schizoid and Histrionic) negatively predicted SPSI-R Positive problem orientation, and narcissistic disorder positively predicted SPSI-R Avoidance style after 6 months in the Latvian Rehabilitation Programme. The other personality disorders did not predict social problem-solving dimensions. The results of the study suggest that some personality disorders are related to changes in social problem-solving dimensions for drug-addicted patients. Hence, it is important to consider the implications of particular personality disorders to facilitate the implementation of social problem-solving rehabilitation programmes.

2014-09-30

Individuals with posttraumatic stress disorder (PTSD) commonly make efforts to avoid trauma-oriented conversations with their significant others, which may interfere with the natural recovery process. Trauma-oriented conversations can be experienced as physiologically arousing, depending on the intensity of PTSD symptoms and perceptions of social support. In the current investigation, changes in heart rate responses to a trauma-oriented social interaction with a significant other were assessed. Perceived supportive and unsupportive or negative social interactions were examined as moderators of the association between heart rate changes to this context and intensity of PTSD symptoms. A total of 46 individuals with PTSD completed diagnostic interviews and self-report measures of symptoms and perceived supportive and negative social interactions during a trauma-oriented social interaction with a significant other. Heart rate was continuously measured during this interaction. Results showed that engagement in a trauma-oriented social interaction was predictive of elevations in heart rate that positively correlated with intensity of PTSD symptoms. The moderation hypothesis was partially supported. In addition, perceived negative social interactions positively correlated with elevations in heart rate. These findings can inform social intervention efforts for individuals with PTSD. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

The effect of regulatory mode on procrastination: Bi-stable parahippocampus connectivity with dorsal anterior cingulate and anterior prefrontal cortex.

PubMed

Zhang, Chenyan; Ni, Yan; Feng, Tingyong

2017-06-30

Previous research has elucidated that procrastination can be influenced by regulatory mode orientations. However, the neural mechanism of regulatory modes affecting procrastination is not well understood. To address this question, we employed resting-state functional magnetic resonance imaging (RS-fMRI) to test the influence of two regulatory modes (assessment and locomotion) on procrastination. The behavioral results showed that procrastination was positively correlated with assessment orientation but negatively correlated with locomotion orientation. Neuroimaging results indicated that the functional connectivity between parahippocampal cortex (PHC) and dorsal anterior cingulate (dACC) was negatively correlated with assessment scores, while the functional connectivity between anterior prefrontal cortex (aPFC) and parahippocampal cortex (PHC) was negatively correlated with locomotion scores. Critically, mediation analysis showed that the different effects of two distinct regulatory modes on procrastination were mediated by PHC-dACC and aPFC-PHC functional connectivity respectively. These results suggested that people's procrastination could be predicted by regulatory mode orientations, which is mediated by PHC connectivity with dACC and aPFC respectively. The present study extends our knowledge on procrastination and provides neural mechanism for understanding the link between regulatory mode orientations and procrastination. Copyright © 2017.

Social Orientation: Problem Behavior and Motivations Toward Interpersonal Problem Solving Among High Risk Adolescents

Kuperminc, Gabriel P.; Allen, Joseph P.

2006-01-01

A model of problematic adolescent behavior that expands current theories of social skill deficits in delinquent behavior to consider both social skills and orientation toward the use of adaptive skills was examined in an ethnically and socioeconomically diverse sample of 113 male and female adolescents. Adolescents were selected on the basis of moderate to serious risk for difficulties in social adaptation in order to focus on the population of youth most likely to be targeted by prevention efforts. Structural equation modeling was used to examine cross-sectional data using multiple informants (adolescents, peers, and parents) and multiple methods (performance test and self-report). Adolescent social orientation, as reflected in perceived problem solving effectiveness, identification with adult prosocial values, and self-efficacy expectations, exhibited a direct association to delinquent behavior and an indirect association to drug involvement mediated by demonstrated success in using problem solving skills. Results suggest that the utility of social skill theories of adolescent problem behaviors for informing preventive and remedial interventions can be enhanced by expanding them to consider adolescents’ orientation toward using the skills they may already possess.

2017-01-01

The paper reviews the role of object-oriented programming when developing software in geology and geophysics. Main stages have been identified at which it is worthwhile to apply principles of object-oriented programming when developing software in geology and geophysics. The research was based on a number of problems solved in Geology and Petroleum Production Institute. Distinctive features of these problems are given and areas of application of the object-oriented approach are identified. Developing applications in the sphere of geology and geophysics has shown that the process of creating such products is simplified due to the use of object-oriented programming, firstly when designing structures for data storage and graphical user interfaces.

2015-01-01

The ability of the visual system to compensate for differences in blur orientation between eyes is not well understood. We measured the orientation of the internal blur code in both eyes of the same subject monocularly by presenting pairs of images blurred with real ocular point spread functions (PSFs) of similar blur magnitude but varying in orientations. Subjects assigned a level of confidence to their selection of the best perceived image in each pair. Using a classification-images–inspired paradigm and applying a reverse correlation technique, a classification map was obtained from the weighted averages of the PSFs, representing the internal blur code. Positive and negative neural PSFs were obtained from the classification map, representing the neural blur for best and worse perceived blur, respectively. The neural PSF was found to be highly correlated in both eyes, even for eyes with different ocular PSF orientations (rPos = 0.95; rNeg = 0.99; p < 0.001). We found that in subjects with similar and with different ocular PSF orientations between eyes, the orientation of the positive neural PSF was closer to the orientation of the ocular PSF of the eye with the better optical quality (average difference was ∼10°), while the orientation of the positive and negative neural PSFs tended to be orthogonal. These results suggest a single internal code for blur with orientation driven by the orientation of the optical blur of the eye with better optical quality. PMID:26114678

Alexithymia Components Are Differentially Related to Explicit Negative Affect But Not Associated with Explicit Positive Affect or Implicit Affectivity.

PubMed

Suslow, Thomas; Donges, Uta-Susan

2017-01-01

Alexithymia represents a multifaceted personality construct defined by difficulties in recognizing and verbalizing emotions and externally oriented thinking. According to clinical observations, experience of negative affects is exacerbated and experience of positive affects is decreased in alexithymia. Findings from research based on self-report indicate that all alexithymia facets are negatively associated with the experience of positive affects, whereas difficulties identifying and describing feelings are related to heightened negative affect. Implicit affectivity, which can be measured using indirect assessment methods, relates to processes of the impulsive system. The aim of the present study was to examine, for the first time, the relations between alexithymia components and implicit and explicit positive and negative affectivity in healthy adults. The 20-item Toronto Alexithymia Scale, the Implicit Positive and Negative Affect Test and the Positive and Negative Affect Schedule (PANAS) were administered to two hundred and forty-one healthy individuals along with measures of depression and trait anxiety. Difficulties identifying feelings were correlated with explicit negative trait affect, depressive mood and trait anxiety. Difficulties describing feelings showed smaller but also significant correlations with depressive mood and trait anxiety but were not correlated with explicit state or trait affect as assessed by the PANAS. Externally oriented thinking was not significantly correlated with any of the implicit and explicit affect measures. According to our findings, an externally oriented, concrete way of thinking appears to be generally unrelated to dispositions to develop positive or negative affects. Difficulties identifying feelings seem to be associated with increased conscious negative affects but not with a heightened disposition to develop negative affects at an automatic response level.

Context Oriented Information Integration

Mohania, Mukesh; Bhide, Manish; Roy, Prasan; Chakaravarthy, Venkatesan T.; Gupta, Himanshu

Faced with growing knowledge management needs, enterprises are increasingly realizing the importance of seamlessly integrating critical business information distributed across both structured and unstructured data sources. Academicians have focused on this problem but there still remain a lot of obstacles for its widespread use in practice. One of the key problems is the absence of schema in unstructured text. In this paper we present a new paradigm for integrating information which overcomes this problem - that of Context Oriented Information Integration. The goal is to integrate unstructured data with the structured data present in the enterprise and use the extracted information to generate actionable insights for the enterprise. We present two techniques which enable context oriented information integration and show how they can be used for solving real world problems.

Anisotropic norm-oriented mesh adaptation for a Poisson problem

NASA Astrophysics Data System (ADS)

Brèthes, Gautier; Dervieux, Alain

2016-10-01

We present a novel formulation for the mesh adaptation of the approximation of a Partial Differential Equation (PDE). The discussion is restricted to a Poisson problem. The proposed norm-oriented formulation extends the goal-oriented formulation since it is equation-based and uses an adjoint. At the same time, the norm-oriented formulation somewhat supersedes the goal-oriented one since it is basically a solution-convergent method. Indeed, goal-oriented methods rely on the reduction of the error in evaluating a chosen scalar output with the consequence that, as mesh size is increased (more degrees of freedom), only this output is proven to tend to its continuous analog while the solution field itself may not converge. A remarkable quality of goal-oriented metric-based adaptation is the mathematical formulation of the mesh adaptation problem under the form of the optimization, in the well-identified set of metrics, of a well-defined functional. In the new proposed formulation, we amplify this advantage. We search, in the same well-identified set of metrics, the minimum of a norm of the approximation error. The norm is prescribed by the user and the method allows addressing the case of multi-objective adaptation like, for example in aerodynamics, adaptating the mesh for drag, lift and moment in one shot. In this work, we consider the basic linear finite-element approximation and restrict our study to L2 norm in order to enjoy second-order convergence. Numerical examples for the Poisson problem are computed.

Gender and Intergroup Helping: Forms of Prosocial Behavior as Differential Social Control Mechanisms for Women and Men.

Abad-Merino, Silvia; Dovidio, John F; Tabernero, Carmen; González, Ignacio

2016-10-20

The present research, drawing on the Intergroup Helping as Power Relations Model (Nadler, 2002), investigated the ways in which different forms of helping behavior can strategically affect responses to women and men who display socially valued or devalued characteristics. Participants read scenarios about concrete problems faced by a woman or man in need, who displayed positive (i.e., prosocial) or negative (i.e., antisocial) characteristics, and indicated the extent to which they would be willing to support small tax increases if that money were used to help address the target's issues. The predicted Target Gender × Target History × Type of Support interaction, controlling for political orientation, was obtained, F(1, 149) = 6.49, p = .012, η p 2 = .04. Participants tended to give less autonomy-oriented (i.e., empowering) help to a man displaying antisocial (vs. prosocial) characteristics, F(1, 36) = 3.39, p = .074, η p 2 = .09.; they also tended to off more dependency-oriented (i.e., disempowering) help to a woman women exhibiting prosocial (vs. antisocial) qualities, F(1, 38) = 3.42, p = .072, η p 2 = .08. The role of seemingly positive forms of social behavior as a mechanism for social control and the relation of helping to processes of group-hierarchy and system-justifying processes are considered.

2007-01-01

To carry out a study using cognitive processing interview methods to explore ways in which adolescents understand sexual orientation questions currently used on epidemiologic surveys. In-depth, individual interviews were conducted to probe cognitive processes involved in answering four self-report survey questions assessing sexual identity, sexual attraction, and sex of sexual partners.A semi-structured interview guide was used to explore variation in question interpretation, information retrieval patterns and problems, item clarity, valence of reactions to items (positive, negative, neutral), respondent burden, and perceived threat associated with the measures. Thirty adolescents aged 15 to 21 of diverse sexual orientations and race/ethnicities participated in the study, including female, male, and transgender youth. A question on sexual attraction was the most consistently understood and thus was easy for nearly all youth to answer. In contrast, a measure of sexual identity with options heterosexual, bisexual, gay/lesbian, and unsure was the most difficult to answer. Most preferred a sexual identity item that also provided the intermediate options mostly heterosexual and mostly homosexual, which many said reflected their experience of feeling between categories. Participants had varying and inconsistent interpretations of sexual behavior terms, such as sex and sexual intercourse, used in assessing the sex of sexual partners. Differences in understanding could affect interpretation of survey data in important ways. Development of valid measures of sexual orientation will be essential to better monitor health disparities.

Quality of Life and Coping Strategies in Coronary Heart Disease Patients

This study aims to find the relationship between quality of life and coping strategies in coronary heart disease patients. Two hundred coronary heart disease patients at Tehran Heart Center, who had been diagnosed with the disease 3 months before, were selected and filled out The Coping Inventory for Stressful Situations (CISS) and Quality of Life-SF36. Results showed a discrepancy between quality of life indices and coping strategies. Task-oriented strategy had a positive and significant relationship with total quality of life and PF indices while it had a negative and significant relationship with MH, RE and RP indices. Emotional-oriented strategy had a positive and significant relationship with RP and RE indices while it had a negative and significant relationship with PF, GH, PH, total psychological health and total quality of life indices. Avoidance-oriented strategy had a negative and significant relationship only with MH index. Furthermore, quality of life aspects (physical and psychological) had a positive and significant relationship with emotional-oriented strategy, but it did not have a significant relationship with task-oriented and avoidance-oriented strategies. Also, the social aspect of quality of life did not have a significant relationship with any of the strategies. Considering the effect of stress on decreasing the quality of life, we recommend a psychologist train coping strategies to coronary heart disease patients along with medical treatments in order to improve recovery, maintain health and reduce recurrence.

Coping and family relationships in stress resistance: a study of job satisfaction of nurses in Singapore.

PubMed

Boey, K W

1998-12-01

This study examined the role of coping strategies and family relationships in mitigating the negative effect of work stress on nurses. The findings indicated that nurses who adapted to work stress with high job satisfaction were more inclined to adopt approach coping methods (problem orientation, ability enhancement, and change of perspective) than those who reported low job satisfaction under high work stress. The stress-resistant nurses were also distinguished by a less frequent use of defensive or avoidance coping in handling of their emotional reactions to stress. They perceived greater family support than did the distressed nurses. Implications of the findings and limitation of the study were discussed.

Research has shown that patients' and practitioners' cultural orientations affect communication behaviors and interpretations in cross-cultural patient-practitioner interactions. Little is known about the effect of cultural orientations on assessment of communication behaviors in cross-cultural educational settings. The purpose of this study is to explore cultural orientation as a potential source of assessor idiosyncrasy or between-assessor variability in assessment of communication skills. More specifically, we explored if and how (expert) assessors' valuing of communication behaviours aligned with their cultural orientations (power-distance, masculinity-femininity, uncertainty avoidance, and individualism-collectivism). Twenty-five pharmacist-assessors watched 3 videotaped scenarios (patient-pharmacist interactions) and ranked each on a 5-point global rating scale. Videotaped scenarios demonstrated combinations of well-portrayed and borderline examples of instrumental and affective communication behaviours. We used stimulated recall and verbal protocol analysis to investigate assessors' interpretations and evaluations of communication behaviours. Uttered assessments of communication behaviours were coded as instrumental (task-oriented) or affective (socioemotional) and either positive or negative. Cultural orientations were measured using the Individual Cultural Values Scale. Correlations between cultural orientations and global scores, and frequencies of positive, negative, and total utterances of instrumental and affective behaviours were determined. Correlations were found to be scenario specific. In videos with poor or good performance, no differences were found across cultural orientations. When borderline performance was demonstrated, high power-distance and masculinity were significantly associated with higher global ratings (r = .445, and .537 respectively, p < 0.05) as well as with fewer negative utterances regarding instrumental (task focused) behaviours (r = -.533 and - .529, respectively). Higher masculinity scores were furthermore associated with positive utterances of affective (socioemotional) behaviours (r = .441). Our findings thus confirm cultural orientation as a source of assessor idiosyncrasy and meaningful variations in interpretation of communication behaviours. Interestingly, expert assessors generally agreed on scenarios of good or poor performances but borderline performance was influenced by cultural orientation. Contrary to current practices of assessor and assessment instrument standardization, findings support the use of multiple assessors for patient-practitioner interactions and development of qualitative assessment tools to capture these varying, yet valid, interpretations of performance.

SU-E-J-174: Adaptive PET-Based Dose Painting with Tomotherapy

DOE Office of Scientific and Technical Information (OSTI.GOV)

Darwish, N; Mackie, T; Thomadsen, B

2014-06-01

Purpose: PET imaging can be converted into dose prescription directly. Due to the variability of the intensity of PET the image, PET prescription maybe superior over uniform dose prescription. Furthermore, unlike the case in image reconstruction of not knowing the image solution in advance, the prescribed dose is known from a PET image a priori. Therefore, optimum beam orientations are derivable. Methods: We can assume the PET image to be the prescribed dose and invert it to determine the energy fluence. The same method used to reconstruct tissue images from projections could be used to solve the inverse problem ofmore » determining beam orientations and modulation patterns from a dose prescription [10]. Unlike standard tomographic reconstruction of images from measured projection profiles, the inversion of the prescribed dose results in photon fluence which may be negative and therefore unphysical. Two-dimensional modulated beams can be modelled in terms of the attenuated or exponential radon transform of the prescribed dose function (assumed to be the PET image in this case), an application of a Ram-Lak filter, and inversion by backprojection. Unlike the case in PET processing, however, the filtered beam obtained from the inversion represents a physical photon fluence. Therefore, a positivity constraint for the fluence (setting negative fluence to zero) must be applied (Brahme et al 1982, Bortfeld et al 1990) Results: Truncating the negative profiles from the PET data results in an approximation of the derivable energy fluence. Backprojection of the deliverable fluence is an approximation of the dose delivered. The deliverable dose is comparable to the original PET image and is similar to the PET image. Conclusion: It is possible to use the PET data or image as a direct indicator of deliverable fluence for cylindrical radiotherapy systems such as TomoTherapy.« less

Blaming for a better future: future orientation and associated intolerance of personal uncertainty lead to harsher reactions toward innocent victims.

PubMed

Bal, Michèlle; van den Bos, Kees

2012-07-01

People are often encouraged to focus on the future and strive for long-term goals. This noted, the authors argue that this future orientation is associated with intolerance of personal uncertainty, as people usually cannot be certain that their efforts will pay off. To be able to tolerate personal uncertainty, people adhere strongly to the belief in a just world, paradoxically resulting in harsher reactions toward innocent victims. In three experiments, the authors show that a future orientation indeed leads to more negative evaluations of an innocent victim (Study 1), enhances intolerance of personal uncertainty (Study 2), and that experiencing personal uncertainty leads to more negative evaluations of a victim (Study 3). So, while a future orientation enables people to strive for long-term goals, it also leads them to be harsher toward innocent victims. One underlying mechanism causing these reactions is intolerance of personal uncertainty, associated with a future orientation.

Mostly Heterosexual and Lesbian/Gay Young Adults: Differences in Mental Health and Substance Use and the Role of Minority Stress.

PubMed

Kuyper, Lisette; Bos, Henny

2016-09-01

Individuals mostly attracted to other-sex but also to same-sex partners are a distinct and common sexual orientation group with possibly increased levels of health problems. The current study examined whether mostly heterosexual individuals differed in mental health and substance use from lesbian/gay individuals and whether sexual minority risk and protective factors offer an explanation in a sample of 528 Dutch young adults (16 to 25 years old, M = 21.2 years). Mostly heterosexual participants reported higher levels of psychological distress, suicidality, drug use, and smoking than lesbian/gay participants and equal levels of binge drinking. They also reported higher levels of internalized negativity to same-sex attractions, less openness to family members and others, less community involvement, and lower numbers of lesbian/gay/bisexual friends. However, bootstrapped mediation analysis showed that the differences in minority stress risk and protective factors did not mediate most of the differences in mental health and substance use with one exception: higher levels of psychological distress were mediated by the higher levels of internalized negativity to same-sex attractions. The limited explanatory power of the minority stress factors combined with the elevated level of problems of mostly heterosexual individuals call for future studies examining other risk and protective factors.

Feeling Better When Someone Is Alike: Poor Emotion Regulators Profit From Pro-Social Values and Priming for Similarities With Close Others.

PubMed

Chatterjee, Monischa B; Baumann, Nicola; Koole, Sander L

2017-12-01

The dispositional inability to self-regulate one's own emotions intuitively is described as state orientation and has been associated with numerous psychological impairments. The necessity to search for buffering effects against negative outcomes of state orientation is evident. Research suggests that state-oriented individuals can benefit from feeling close to others. Yet, there are individual differences in the extent to which supportive relationships are valued. The objective of the present article was to examine whether high importance of relatedness increases the utilization of its situational activation among state-oriented individuals. In two studies, we examined whether situational activation of relatedness (by priming for similarities with a close other) is particularly advantageous for state-oriented individuals who attach high importance to relatedness (i.e., benevolence values). The sample consisted of 170 psychology undergraduates in Study 1 and 177 in Study 2. In both studies, state-oriented participants high in benevolence had reduced negative mood after thinking about similarities (vs. differences). State-oriented participants low in benevolence did not benefit from priming for similarities. In Study 2, physical presence of a close other did not boost priming effects for state-oriented participants but stimulated action-oriented participants to attune their self-regulatory efforts to the context. The results show that state-oriented individuals who value benevolence do benefit from a situational activation of relatedness. © 2016 Wiley Periodicals, Inc.

The politics of insight

Previous studies showed that liberals and conservatives differ in cognitive style. Liberals are more flexible, and tolerant of complexity and novelty, whereas conservatives are more rigid, are more resistant to change, and prefer clear answers. We administered a set of compound remote associate problems, a task extensively used to differentiate problem-solving styles (via insight or analysis). Using this task, several researches have proven that self-reports, which differentiate between insight and analytic problem-solving, are reliable and are associated with two different neural circuits. In our research we found that participants self-identifying with distinct political orientations demonstrated differences in problem-solving strategy. Liberals solved significantly more problems via insight instead of in a step-by-step analytic fashion. Our findings extend previous observations that self-identified political orientations reflect differences in cognitive styles. More specifically, we show that type of political orientation is associated with problem-solving strategy. The data converge with previous neurobehavioural and cognitive studies indicating a link between cognitive style and the psychological mechanisms that mediate political beliefs. PMID:26810954

The effect of music-induced mood on attentional networks.

PubMed

Jiang, Jun; Scolaro, Ashley J; Bailey, Kira; Chen, Antao

2011-06-01

Attention network theory suggests that there are three separate neural networks that execute the discrete functions of alerting, orienting, and executive attention. Previous research on the influence of mood on attention has shown subtle and inconsistent results. The attention network theory may aid in clarifying the influence of mood on attention. The present study investigated the influence of mood on attentional networks in a normal population. Participants performed the Attention Network Test (ANT), which provides functional measures of alerting, orienting, and executive attention. Positive or negative mood was induced by listening to music with a positive or negative valence, respectively; neutral mood was induced by reading a collection of basic facts about China. The results revealed that negative mood led to a significantly higher alerting efficiency relative to other moods, while there were no significant mood effects on orienting or executive attention efficiency. According to the algorithm underlying the ANT, the higher alerting efficiency in the negative mood condition can be attributed to relatively greater benefits of cueing effects. The findings are discussed in the context of the noradrenergic system and of evolutionary significance. Specifically, the increase in the alerting function during negative mood states may be due to the modulation effect of negative mood on the noradrenergic system, and/or to the survival benefit resulting from an increase in automatic vigilance towards negative information. The current results suggest that as the influence of negative mood on attention appears to specifically consist in an enhanced alerting function, it may not be found in studies where the three attentional networks are not dissociated.

Representing object oriented specifications and designs with extended data flow notations

Buser, Jon Franklin; Ward, Paul T.

1988-01-01

The issue of using extended data flow notations to document object oriented designs and specifications is discussed. Extended data flow notations, for the purposes here, refer to notations that are based on the rules of Yourdon/DeMarco data flow analysis. The extensions include additional notation for representing real-time systems as well as some proposed extensions specific to object oriented development. Some advantages of data flow notations are stated. How data flow diagrams are used to represent software objects are investigated. Some problem areas with regard to using data flow notations for object oriented development are noted. Some initial solutions to these problems are proposed.

Fabric analysis of quartzites with negative magnetic susceptibility - Does AMS provide information of SPO or CPO of quartz?

NASA Astrophysics Data System (ADS)

Renjith, A. R.; Mamtani, Manish A.; Urai, Janos L.

2016-01-01

We ask the question whether petrofabric data from anisotropy of magnetic susceptibility (AMS) analysis of deformed quartzites gives information about shape preferred orientation (SPO) or crystallographic preferred orientation (CPO) of quartz. Since quartz is diamagnetic and has a negative magnetic susceptibility, 11 samples of nearly pure quartzites with a negative magnetic susceptibility were chosen for this study. After performing AMS analysis, electron backscatter diffraction (EBSD) analysis was done in thin sections prepared parallel to the K1K3 plane of the AMS ellipsoid. Results show that in all the samples quartz SPO is sub-parallel to the orientation of the magnetic foliation. However, in most samples no clear correspondance is observed between quartz CPO and K1 (magnetic lineation) direction. This is contrary to the parallelism observed between K1 direction and orientation of quartz c-axis in the case of undeformed single quartz crystal. Pole figures of quartz indicate that quartz c-axis tends to be parallel to K1 direction only in the case where intracrystalline deformation of quartz is accommodated by prism slip. It is therefore established that AMS investigation of quartz from deformed rocks gives information of SPO. Thus, it is concluded that petrofabric information of quartzite obtained from AMS is a manifestation of its shape anisotropy and not crystallographic preferred orientation.

2013-01-01

This study adopted a spillover-crossover model to examine the roles of personality and perceived social support as antecedents of the work-family interface among dual-earner couples in China. Married couples (N = 306) from 2 major cities in China (Shanghai and Jinan) completed questionnaires measuring a relationship-oriented personality trait (i.e., family orientation), perceived family and work support, and work-family conflict and enhancement. The results showed that family orientation and perceived family support was positively associated with family-to-work enhancement and negatively associated with family-to-work conflict for both husbands and wives. Perceived work support was positively associated with family-to-work enhancement for wives and negatively associated with work-to-family conflict for husbands. Similarities in family orientation between partners were positively correlated with the individual's family-to-work enhancement. This study also illustrated the crossover of the work-family interface between dual-earner couples by using the actor-partner interdependence model. The pattern of associations between personality trait and perceived social support varied by gender. Husbands' family orientation was negatively correlated with work-to-family enhancement experienced by wives, and husbands' perceived work support was positively correlated with work-to-family enhancement experienced by wives. Wives' perceived work support was positively correlated with family-to-work conflict experienced by husbands.

To experimentally test the effects of physician's affect-oriented communication and inducing expectations on outcomes in patients with menstrual pain. Using a 2×2 RCT design, four videotaped simulated medical consultations were used, depicting a physician and a patient with menstrual pain. In the videos, two elements of physician's communication were manipulated: (1) affect-oriented communication (positive: warm, emphatic; versus negative: cold, formal), and (2) outcome expectation induction (positive versus uncertain). Participants (293 women with menstrual pain), acting as analogue patients, viewed one of the four videos. Pre- and post video participants' outcomes (anxiety, mood, self-efficacy, outcome expectations, and satisfaction) were assessed. Positive affect-oriented communication reduced anxiety (p<0.001), negative mood (p=0.001), and increased satisfaction (p<0.001) compared to negative affect-oriented communication. Positive expectations increased feelings of self-efficacy (p<0.001) and outcome expectancies (p<0.001), compared to uncertain expectations, but did not reduce anxiety. The combination of positive affect-oriented communication and a positive expectation reduced anxiety (p=0.02), increased outcome expectancies (p=0.01) and satisfaction (p=0.001). Being empathic and inducing positive expectations have distinct and combined effects, demonstrating that both are needed to influence patients' outcomes for the best. Continued medical training is needed to harness placebo-effects of medical communication into practice. Copyright © 2017 Elsevier B.V. All rights reserved.

Qualitative methods: beyond the cookbook.

PubMed

Harding, G; Gantley, M

1998-02-01

Qualitative methods appear increasingly in vogue in health services research (HSR). Such research, however, has utilized, often uncritically, a 'cookbook' of methods for data collection, and common-sense principles for data analysis. This paper argues that qualitative HSR benefits from recognizing and drawing upon theoretical principles underlying qualitative data collection and analysis. A distinction is drawn between problem-orientated and theory-orientated research, in order to illustrate how problem-orientated research would benefit from the introduction of theoretical perspectives in order to develop the knowledge base of health services research.

Toward a Developmentally-Informed Approach to Parenting Interventions: Seeking Hidden Effects

Brock, Rebecca L.; Kochanska, Grazyna

2015-01-01

Drawing from developmental psychology and psychopathology, we propose a new, developmentally-informed approach to parenting interventions that focuses on elucidating changes in the unfolding developmental process between the parent and child. We present data from 186 low-income mothers of toddlers, randomly assigned to Child-Oriented Play group or Play-as-Usual group. We examined the maladaptive cascade from child difficulty to mother adversarial, negative parenting to child maladjustment, well documented in the literature. The measures incorporated multiple observations and reports. As expected, the sequence from child difficulty (Pretest) to mother adversarial, negative parenting (Posttest 1, after 3-month intervention) to child maladjustment (Posttest 2, 6 months later) was present in Play-as-Usual group, but absent, or defused, in Child-Oriented Play group. The findings are consistent with a view of intervention presumably enhancing the mother-child relationship, which in turn served to moderate future mother-child dynamics, altering its otherwise anticipated negative trajectory. A closer examination of the cascade revealed that, at Posttest 1, mothers in Play-as-Usual group engaged in more adversarial, negative parenting (controlling for Pretest) than mothers in Child-Oriented Play group when their children were of high difficulty. The intervention appears to exert its primary influence on the cascade by weakening the link between child difficulty and maternal adversarial, negative parenting. PMID:27063895

A generalized self-consistent polycrystal model for the yield strength of nanocrystalline materials

NASA Astrophysics Data System (ADS)

Jiang, B.; Weng, G. J.

2004-05-01

Inspired by recent molecular dynamic simulations of nanocrystalline solids, a generalized self-consistent polycrystal model is proposed to study the transition of yield strength of polycrystalline metals as the grain size decreases from the traditional coarse grain to the nanometer scale. These atomic simulations revealed that a significant portion of atoms resides in the grain boundaries and the plastic flow of the grain-boundary region is responsible for the unique characteristics displayed by such materials. The proposed model takes each oriented grain and its immediate grain boundary to form a pair, which in turn is embedded in the infinite effective medium with a property representing the orientational average of all these pairs. We make use of the linear comparison composite to determine the nonlinear behavior of the nanocrystalline polycrystal through the concept of secant moduli. To this end an auxiliary problem of Christensen and Lo (J. Mech. Phys. Solids 27 (1979) 315) superimposed on the eigenstrain field of Luo and Weng (Mech. Mater. 6 (1987) 347) is first considered, and then the nonlinear elastoplastic polycrystal problem is addressed. The plastic flow of each grain is calculated from its crystallographic slips, but the plastic behavior of the grain-boundary phase is modeled as that of an amorphous material. The calculated yield stress for Cu is found to follow the classic Hall-Petch relation initially, but as the gain size decreases it begins to depart from it. The yield strength eventually attains a maximum at a critical grain size and then the Hall-Petch slope turns negative in the nano-range. It is also found that, when the Hall-Petch relation is observed, the plastic behavior of the polycrystal is governed by crystallographic slips in the grains, but when the slope is negative it is governed by the grain boundaries. During the transition both grains and grain boundaries contribute competitively.

Restart Operator Meta-heuristics for a Problem-Oriented Evolutionary Strategies Algorithm in Inverse Mathematical MISO Modelling Problem Solving

2017-02-01

This study is focused on solving an inverse mathematical modelling problem for dynamical systems based on observation data and control inputs. The mathematical model is being searched in the form of a linear differential equation, which determines the system with multiple inputs and a single output, and a vector of the initial point coordinates. The described problem is complex and multimodal and for this reason the proposed evolutionary-based optimization technique, which is oriented on a dynamical system identification problem, was applied. To improve its performance an algorithm restart operator was implemented.

Engineering negative differential conductance with the Cu(111) surface state.

Low-temperature scanning tunneling microscopy and spectroscopy are employed to investigate electron tunneling from a C60-terminated tip into a Cu(111) surface. Tunneling between a C60 orbital and the Shockley surface states of copper is shown to produce negative differential conductance (NDC) contrary to conventional expectations. NDC can be tuned through barrier thickness or C60 orientation up to complete extinction. The orientation dependence of NDC is a result of a symmetry matching between the molecular tip and the surface states.

Children's adjustment in non-traditional families in Israel: the effect of parental sexual orientation and the number of parents on children's development.

2013-03-01

This study examined differences in children's psychological and social indicators in non-traditional families in Israel, focusing on fatherless families headed by lesbian mothers and single mothers by choice. Although Israel is considered an industrialized westernized country, centrality of the traditional nuclear family predominates this country. This factorial design study included four family types: lesbian and heterosexual mothers, each in both single and coupled parenthood. Children's measures included the Child Behavior Checklist, perception of peer relations and perceived self-competence. Children from single parent as opposed to two-parent families exhibited more externalizing behaviour problems and aggressiveness. Children of lesbian mothers reported more prosocial behaviours and less loneliness than children from heterosexual families. No differences emerged for perceived self-competence across family types. Mother's sexual orientation did not affect children's adjustment negatively, whereas single parenthood placed children at greater risk for some difficulties. Implications include the need for apprising health professionals of effects of family types on children's development. © 2011 Blackwell Publishing Ltd.

Gay and bisexual male clients' perceptions of counseling: the role of perceived sexual orientation similarity and counselor universal-diverse orientation.

A recurring question in multicultural counseling is whether client-counselor similarity on sociodemographic characteristics benefits counseling. A related issue is how counselor orientation to diversity relates to counseling process and outcome, both as a main effect and in interaction with counselor-client sociodemographic match. This cross-sectional study investigated these questions in relation to gay and bisexual male clients' counseling experiences by examining clients' perceived similarity to their counselor in sexual orientation, as well as counselors' self-reported orientation to diversity (assessed in terms of level of universal-diverse orientation [UDO]). Data were from 83 male-male client-counselor dyads recruited from lesbian/gay/bisexual-affirming counseling practices, where clients identified as gay or bisexual and counselors identified as gay, bisexual, or heterosexual. Counselor UDO was positively and uniquely associated with client ratings of the working alliance, session depth, and session smoothness. Perceived sexual orientation similarity was not directly related to any of the counseling-related criterion variables. Moreover, when counselors reported low levels of UDO, perceived similarity was negatively associated with the client-rated alliance and perceived improvement. Client religious commitment-a control variable in all analyses--was uniquely and negatively associated with client ratings of perceived improvement in counseling.

Future time orientation and temperament: exploration of their relationship to primary and secondary psychopathy.

PubMed

2009-08-01

The present study combines Lykken's theory about the role of reward sensitivity and punishment insensitivity in the development of antisocial behavior with Gjesme's theory of future time orientation. 158 adolescents comprised a target group of 79 adolescents who had defined behavioral problems and a matched referential group of 79 adolescents who did not have notable behavioral problems. The results suggest that attributes related to primary psychopathy are associated with a relatively weak or hyporeactive behavioral inhibition system, behavioral approach reactivity, and low future time orientation. Moreover, attributes related to secondary psychopathy are related to an overly sensitive (hyper-reactive) behavioral approach system and low future time orientation. Robust positive associations for behavioral approach reactivity and low future time orientation with primary and secondary psychopathy suggest that high behavioral approach/low future time orientation may represent a core feature common to the two factors of psychopathy.

Perceived Parental Monitoring and Sexual Orientation Moderate Lifetime Acts of Non-Suicidal Self-Injury.

Benau, Erik M; Jenkins, Abigail L; Conner, Bradley T

2017-01-01

Being non-heterosexual, particularly bisexual, is associated with high rates of engagement in NSSI amongst young adults. The goal of the present study was to determine if parenting practices, specifically parental monitoring, and sexual orientation moderate engagement with NSSI. Undergraduates (N = 1,353) completed a survey on sexual orientation, non-suicidal self-injury (NSSI) acts, and multiple aspects of perceived parental monitoring during high school. Moderation analyses revealed that most facets of parental monitoring were similarly negatively correlated with NSSI for both individuals whose sexual orientation where nearly, or entirely, gay and heterosexual youth. Youth who were neither exclusively heterosexual nor exclusively gay (mixed sexual orientation) reported the most NSSI acts, and no facet of parental monitoring predicted reduced NSSI acts for this group. While previous literature shows that many aspects of parental monitoring may be protective against engagement in health risk behaviors, the present study adds to these findings that similar aspects are negatively associated with self-injurious behavior for some, but not all, individuals. More research is needed to better understand the causes of increased NSSI for individuals with a mixed sexual orientation.

AUTISTIC TRAITS INFLUENCE GAZE-ORIENTED ATTENTION TO HAPPY BUT NOT FEARFUL FACES

PubMed Central

Lassalle, Amandine; Itier, Roxane J.

2017-01-01

The relationship between autistic traits and gaze-oriented attention to fearful and happy faces was investigated at the behavioral and neuronal levels. Upright and inverted dynamic face stimuli were used in a gaze-cueing paradigm while ERPs were recorded. Participants responded faster to gazed-at than to non-gazed-at targets and this Gaze Orienting Effect (GOE) diminished with inversion, suggesting it relies on facial configuration. It was also larger for fearful than happy faces but only in participants with high Autism Quotient (AQ) scores. While the GOE to fearful faces was of similar magnitude regardless of AQ scores, a diminished GOE to happy faces was found in participants with high AQ scores. At the ERP level, a congruency effect on target-elicited P1 component reflected enhanced visual processing of gazed-at targets. In addition, cue-triggered early directing attention negativity and anterior directing attention negativity reflected, respectively, attention orienting and attention holding at gazed-at locations. These neural markers of spatial attention orienting were not modulated by emotion and were not found in participants with high AQ scores. Together these findings suggest that autistic traits influence attention orienting to gaze and its modulation by social emotions such as happiness. PMID:25222883

Aggression proneness: Transdiagnostic processes involving negative valence and cognitive systems.

Verona, Edelyn; Bresin, Konrad

2015-11-01

Aggressive behavior is observed in persons with various mental health problems and has been studied from the perspectives of neuroscience and psychophysiology. The present research reviews some of the extant experimental literature to help clarify the interplay between domains of functioning implicated in aggression proneness. We then convey a process-oriented model that elucidates how the interplay of the Negative Valence and Cognitive System domains of NIMH's Research Domain Criteria (RDoC) helps explain aggression proneness, particularly reactive aggression. Finally, we report on a study involving event-related potential (ERP) indices of emotional and inhibitory control processing during an emotional-linguistic go/no-go task among 67 individuals with histories of violence and criminal offending (30% female, 44% African-American) who reported on their aggressive tendencies using the Buss-Perry Aggression Questionnaire. Results provide evidence that tendencies toward angry and aggressive behavior relate to reduced inhibitory control processing (no-go P3) specifically during relevant threat-word blocks, suggesting deterioration of cognitive control by acute or sustained threat sensitivity. These findings highlight the value of ERP methodologies for clarifying the interplay of Negative Valence and Cognitive System processes in aggression proneness. Copyright © 2015 Elsevier B.V.

In this paper we study the orienteering problem with time windows (OPTW) and the impact of relaxing the time windows on the profit collected by the vehicle. The way of relaxing time windows adopted in the orienteering problem with soft time windows (OPSTW) that we study in this research is a late service relaxation that allows linearly penalized late services to customers. We solve this problem heuristically by considering a hybrid iterated local search. The results of the computational study show that the proposed approach is able to achieve promising solutions on the OPTW test instances available in the literature, one new best solution is found. On the newly generated test instances of the OPSTW, the results show that the profit collected by the OPSTW is better than the profit collected by the OPTW.

Pendragon, Diane K

2010-01-01

This article summarizes data from a qualitative study investigating the ways in which female youth perceive and respond to challenges related to the interplay of late adolescence and a minority sexual orientation. Fifteen sexual minority females in late adolescence were interviewed individually and in focus groups. The interviews focused on participants' perceptions of challenges, the impact those stressors have in their lives, and methods they utilize to cope with them. The most common negative experiences reported were isolation, lack of acceptance, harassment, and violence. Sub-themes include: hearing negative messages about gender and sexual orientation, pressures to conform to a variety of cultural norms including gender norms, fears of future violence, and pressure to identify sexual orientation. Collectively, the participants described these negative consequences of experiences of heterosexism, sexism, and racism as their most difficult experiences. The most common responses to these stressors reported by participants were finding support in relationships, engaging in coping responses, pursuing education and activism, rebellion and resistance, and avoidance and deferment.

Virtual and flexible digital signal processing system based on software PnP and component works

NASA Astrophysics Data System (ADS)

He, Tao; Wu, Qinghua; Zhong, Fei; Li, Wei

2005-05-01

An idea about software PnP (Plug & Play) is put forward according to the hardware PnP. And base on this idea, a virtual flexible digital signal processing system (FVDSPS) is carried out. FVDSPS is composed of a main control center, many sub-function modules and other hardware I/O modules. Main control center sends out commands to sub-function modules, and manages running orders, parameters and results of sub-functions. The software kernel of FVDSPS is DSP (Digital Signal Processing) module, which communicates with the main control center through some protocols, accept commands or send requirements. The data sharing and exchanging between the main control center and the DSP modules are carried out and managed by the files system of the Windows Operation System through the effective communication. FVDSPS real orients objects, orients engineers and orients engineering problems. With FVDSPS, users can freely plug and play, and fast reconfigure a signal process system according to engineering problems without programming. What you see is what you get. Thus, an engineer can orient engineering problems directly, pay more attention to engineering problems, and promote the flexibility, reliability and veracity of testing system. Because FVDSPS orients TCP/IP protocol, through Internet, testing engineers, technology experts can be connected freely without space. Engineering problems can be resolved fast and effectively. FVDSPS can be used in many fields such as instruments and meter, fault diagnosis, device maintenance and quality control.

Family relationships and sexual orientation disclosure to family by gay and bisexual men in Jamaica

White, Yohann; Sandfort, Theo; Morgan, Kai; Carpenter, Karen; Pierre, Russell

2016-01-01

Gay and bisexual men in Jamaica encounter stigma and discrimination due to criminalization of and negative attitudes towards same-sex sexuality. Disclosure of sexual orientation may be self-affirming, but could increase exposure to negative responses and stressors. Outcomes of an online survey among 110 gay and bisexual Jamaican men ages 18 to 56 years suggest that disclosure to family is affected by level of economic independence. Furthermore, negative familial responses to sexual identity significantly predicted depression. Social and structural interventions, and efforts to strengthen positive family relationships, are needed to foster an environment that enables well-being among sexual minorities in Jamaica.

Preferred negative geotactic orientation in mobile cells: Tetrahymena results.

PubMed Central

Noever, D A; Cronise, R; Matsos, H C

1994-01-01

For the protozoan species Tetrahymena a series of airplane experiments are reported, which varied gravity as an active laboratory parameter and tested for corresponding changes in geotaxic orientation of single cells. The airplane achieved alternating periods of low (0.01 g) and high (1.8 g; g = 980 cm/s) gravity by flying repeated Keplerian parabolas. The experimental design was undertaken to clearly distinguish gravity from competing aerodynamic and chemical gradients. In this way, each culture served as its own control, with gravity level alone determining the orientational changes. On average, 6.3% of the Tetrahymena oriented vertically in low gravity, while 27% oriented vertically in high-gravity phases. Simplified physical models are explored for describing these cell trajectories as a function of gravity, aerodynamic drag, and lift.

Noever, David A.; Cronise, Raymond; Matsos, Helen C.

1994-01-01

For the protozoan species Tetrahymena a series of airplane experiments are reported, which varied gravity as an active laboratory parameter and tested for corresponding changes in geotaxic orientation of single cells. The airplane achieved altemating periods of low (0.01 g) and high (1.8 g, g = 980 cm/s) gravity by flying repeated Keplerian parabolas. The experimental design was undertaken to clearly distinguish gravity from competing aerodynamic and chemical gradients. In this way, each culture served as its own control, with gravity level alone determining the orientational changes. On average, 6.3% of the Tetrahymena oriented vertically in low gravity, while 27% oriented vertically in high-gravity phases. Simplified physical models are explored for describing these cell trajectores as a function of gravity, aerodynamic drag, and lift. The notable effect of gravity on turning behavior is emphasized as the biophysical cause of the observed negative geotaxis in Tetrahymena. A fundamental investigation of the biological gravity receptor (it it exists) and improved modeling for vertical migration in important types of ocean plankton motivate the present research.

Aim To retrospectively analyze the rate of multi-type abuse in childhood and the effects of childhood abuse and type of coping strategies on the psychological adaptation of young adults in a sample form the student population of the University of Mostar. Methods The study was conducted on a convenience sample of 233 students from the University of Mostar (196 female and 37 male), with a median age of 20 (interquartile range, 2). Exposure to abuse was determined using the Child Maltreatment Scales for Adults, which assesses emotional, physical, and sexual abuse, neglect, and witnessing family violence. Psychological adaptation was explored by the Trauma Symptom Checklist, which assesses anxiety/depression, sexual problems, trauma symptoms, and somatic symptoms. Strategies of coping with stress were explored by the Coping Inventory for Stressful Situations. Results Multi-type abuse in childhood was experienced by 172 participants (74%) and all types of abuse by 11 (5%) participants. Emotional and physical maltreatment were the most frequent types of abuse and mostly occurred together with other types of abuse. Significant association was found between all types of abuse (r = 0.436-0.778, P < 0.050). Exposure to sexual abuse in childhood and coping strategies were significant predictors of anxiety/depression (R2 = 0.3553), traumatic symptoms (R2 = 0.2299), somatic symptoms (R2 = 0.2173), and sexual problems (R2 = 0.1550, P < 0.001). Conclusion Exposure to multi-type abuse in childhood is a traumatic experience with long-term negative effects. Problem-oriented coping strategies ensure a better psychosocial adaptation than emotion-oriented strategies. PMID:20960590

The sensitivity and specificity of the Middlesex Elderly Assessment of Mental State (MEAMS) for detecting cognitive impairment after stroke.

Cartoni, A; Lincoln, N B

2005-03-01

The aim of the study was to assess the sensitivity and specificity of the MEAMS (Golding, 1989) for detecting cognitive impairment after stroke. Stroke patients admitted to hospital received a cognitive screening assessment, the MEAMS, and a detailed cognitive assessment. The information obtained from the detailed assessment was summarised in a structured written report. From the conclusions in these reports, patients were classified as "impaired" or "not impaired" in perception, memory, executive function and language. The sensitivity and specificity of the MEAMS subtests and the overall number of tests passed were determined in relation to the presence of impairment, as given in the overall conclusion of the written reports. There were 30 stroke patients, aged 58 to 92 (mean 75.80, SD 7.94) years. Of these, 17 were men and 13 were women. The sensitivity of the MEAMS subtests ranged from 11% to 100% and the specificity ranged from 69% to 100%. The sensitivity of the overall MEAMS score was 52% and the specificity was 100%, using a cut-off score of 3 or more fails to indicate impairment. Three subtests, Orientation, Naming and Unusual views had 81% sensitivity and 50% specificity for detecting problems in language, perception or memory. The MEAMS was not a sensitive screen for overall cognitive impairment or for memory, perceptual, language, or executive function problems after stroke, but it was specific. Although screening for cognitive impairment is important, the MEAMS is not recommended as the sole method, as it produces an unacceptably high false negative rate. Three subtests (Orientation, Naming and Unusual views) had 81% sensitivity and 50% specificity for detecting cognitive problems in language, perception or memory after stroke.

Factors associated with the rejection of active euthanasia: a survey among the general public in Austria

PubMed Central

2013-01-01

Background In recent decades, the general public has become increasingly receptive toward a legislation that allows active voluntary euthanasia (AVE). The purpose of this study was to survey the current attitude towards AVE within the Austrian population and to identify explanatory factors in the areas of socio-demographics, personal experiences with care, and ideological orientation. A further objective was to examine differences depending on the type of problem formulation (abstract vs. situational) for the purpose of measuring attitude. Methods A representative cross-sectional study was conducted across the Austrian population. Data were acquired from 1,000 individuals aged 16 years and over based on telephone interviews (CATI). For the purpose of measuring attitude toward AVE, two different problem formulations (abstract vs. situational) were juxtaposed. Results The abstract question about active voluntary euthanasia was answered negatively by 28.8%, while 71.2% opted in favour of AVE or were undecided. Regression analyses showed rejection of AVE was positively correlated with number of adults and children in the household, experience with care of seriously ill persons, a conservative worldview, and level of education. Mean or high family income was associated with lower levels of rejection. No independent correlations were found for variables such as sex, age, political orientation, self-rated health, and experiences with care of terminally ill patients. Correlation for the situational problem formulation was weaker and included fewer predictors than for the abstract question. Conclusions Our results suggest that factors relating to an individual’s interpersonal living situation and his/her cognitive convictions might be important determinants of the attitude toward AVE. If and to the extent that personal care experience plays a role, it is rather associated with rejection than with acceptance of AVE. PMID:23826902

[Variations of time perspective by social deprivation, what are the effects on smoking cessation?].

Merson, F; Guillon, C; Arvers, P; Underner, M; Perriot, J

2012-10-01

Smoking represents a major public health problem because of its high morbidity and mortality rates. Nearly half of the deaths in the lower class are caused by smoking. The socially deprived are physically and psychologically vulnerable. The instability of their situation increases the difficulty to invest in smoking cessation and certain time orientations linked to this social deprivation represent negative factors in the prognosis. Socially deprived populations do not understand the consequences of smoking unless they are in denial of the risks. The motivation to stop is essentially financial. The perception of smoking cessation is taken as a deprivation of pleasure. Independently of the social deprivation factors, taking into account the time perspective conveys necessary information of appropriate care.

Scattering by randomly oriented ellipsoids: Application to aerosol and cloud problems

1979-01-01

A program was developed for computing the scattering and absorption by arbitrarily oriented and randomly oriented prolate and oblate spheroids. This permits examination of the effect of particle shape for cases ranging from needles through spheres to platelets. Applications of this capability to aerosol and cloud problems are discussed. Initial results suggest that the effect of nonspherical particle shape on transfer of radiation through aerosol layers and cirrus clouds, as required for many climate studies, can be readily accounted for by defining an appropriate effective spherical particle radius.

The crack-inclusion interaction problem

Liu, X.-H.; Erdogan, F.

1986-01-01

The general plane elastostatic problem of interaction between a crack and an inclusion is considered. The Green's functions for a pair of dislocations and a pair of concentrated body forces are used to generate the crack and the inclusion. Integral equations are obtained for a line crack and an elastic line inclusion having an arbitrary relative orientation and size. The nature of stress singularity around the end points of rigid and elastic inclusions is described and three special cases of this intersection problem are studied. The problem is solved for an arbitrary uniform stress state away from the crack-inclusion region. The nonintersecting crack-inclusion problem is considered for various relative size, orientation, and stiffness parameters, and the stress intensity factors at the ends of the inclusion and the crack are calculated. For the crack-inclusion intersection case, special stress intensity factors are defined and are calculated for various values of the parameters defining the relative size and orientation of the crack and the inclusion and the stiffness of the inclusion.

Spatial attention can modulate unconscious orientation processing.

Bahrami, Bahador; Carmel, David; Walsh, Vincent; Rees, Geraint; Lavie, Nilli

2008-01-01

It has recently been suggested that visual spatial attention can only affect consciously perceived events. We measured the effects of sustained spatial attention on orientation-selective adaptation to gratings, rendered invisible by prolonged interocular suppression. Spatial attention augmented the orientation-selective adaptation to invisible adaptor orientation. The effect of attention was clearest for test stimuli at peri-threshold, intermediate contrast levels, suggesting that previous negative results were due to assessing orientation discrimination at maximum contrast. On the basis of these findings we propose a constrained hypothesis for the difference between neuronal mechanisms of spatial attention in the presence versus absence of awareness.

Health policy considerations for our sexual minority patients.

PubMed

O'Hanlan, Katherine A

2006-03-01

Homosexuality and transsexuality are still widely viewed by lay individuals as morally negative and deserving of legal proscription. Peer-reviewed data confirm that experiences of legal discrimination are associated with stress-related health problems, reduced utilization of health care, and financial and legal challenges for individuals and families, especially those with children. In the last 3 years, the American Psychiatric Association, American Psychological Association, and American Psychoanalytic Association have each reviewed the research on sexual orientation and identity, and each has confirmed that sexual orientation and gender identity do not correlate with mental illness or immorality. They have each endorsed laws that confer equality to sexual minorities, including nondiscrimination in employment, medical insurance coverage, adoption, and access to civil marriage. The American College of Obstetricians and Gynecologists (ACOG), by virtue of its history of advocacy for women's health, is in a position to promote policy and make similar recommendations, recognizing that sexual minority women's health and their family issues are an integral component of taking care of all women. The College should review the policies of America's premier mental health associations and consider including sexual orientation and gender identity in its own nondiscrimination policy, and ACOG should issue a policy statement in support of laws to provide safety from violence and discrimination, equal employment opportunities, equal health insurance coverage, and equal access to civil marriage.

Larry Weed, MD is widely known as the father of the problem-oriented medical record and inventor of the now-ubiquitous SOAP (subjective/objective/assessment/plan) note, for developing an electronic health record system (Problem-Oriented Medical Information System, PROMIS), and for founding a company (since acquired), which developed problem-knowledge couplers. However, Dr Weed's vision for medicine goes far beyond software--over the course of his storied career, he has relentlessly sought to bring the scientific method to medical practice and, where necessary, to point out shortcomings in the system and advocate for change. In this oral history, Dr Weed describes, in his own words, the arcs of his long career and the work that remains to be done. Published by the BMJ Publishing Group Limited.

Objective To examine the association of problem-solving with functioning in youth with traumatic brain injury (TBI). Design Cross-sectional evaluation of pretreatment data from a randomized controlled trial. Setting Four children’s hospitals and 1 general hospital, with level 1 trauma units. Participants Youth, ages 11 to 18 years, who sustained moderate or severe TBI in the last 18 months (N=153). Main Outcome Measures Problem-solving skills were assessed using the Social Problem-Solving Inventory (SPSI) and the Dodge Social Information Processing Short Stories. Everyday functioning was assessed based on a structured clinical interview using the Child and Adolescent Functional Assessment Scale (CAFAS) and via adolescent ratings on the Youth Self Report (YSR). Correlations and multiple regression analyses were used to examine associations among measures. Results The TBI group endorsed lower levels of maladaptive problem-solving (negative problem orientation, careless/impulsive responding, and avoidant style) and lower levels of rational problem-solving, resulting in higher total problem-solving scores for the TBI group compared with a normative sample (P<.001). Dodge Social Information Processing Short Stories dimensions were correlated (r=.23–.37) with SPSI subscales in the anticipated direction. Although both maladaptive (P<.001) and adaptive (P=.006) problem-solving composites were associated with overall functioning on the CAFAS, only maladaptive problem-solving (P<.001) was related to the YSR total when outcomes were continuous. For the both CAFAS and YSR logistic models, maladaptive style was significantly associated with greater risk of impairment (P=.001). Conclusions Problem-solving after TBI differs from normative samples and is associated with functional impairments. The relation of problem-solving deficits after TBI with global functioning merits further investigation, with consideration of the potential effects of problem-solving interventions on functional outcomes.

Porter, Christopher O L H

2005-07-01

The author examined the predictive validity of goal orientation in teams on both team process and outcome variables. Results indicate that when mean goal orientation scores were used as a way of describing team members' inputs, learning orientation was related to backing up behavior, efficacy, and commitment. The relationships between performance orientation and efficacy and commitment, however, were more complex and were clarified when task performance was also taken into account. Performance orientation had a negative effect on efficacy when task performance was low and a positive effect on commitment when task performance was high. The implications of these findings for theory and research on goal orientation in teams and team staffing are discussed. Copyright 2005 APA, all rights reserved.

It Gets Better: Future Orientation Buffers the Development of Hopelessness and Depressive Symptoms following Emotional Victimization during Early Adolescence

Research consistently has linked hopelessness to a range of negative outcomes, including depression, during adolescence. Although interpersonal stressors such as familial and peer emotional victimization have been found to contribute to hopelessness, less research has examined whether adolescents with a greater tendency to think about and plan for the future (i.e., future orientation) are protected against the development of hopelessness, particularly in the context of negative events. Thus, the current study evaluated whether peer and familial emotional victimization predicted increases in hopelessness more strongly among adolescents with a weaker future orientation than those with a stronger orientation towards the future, and whether hopelessness in turn predicted increases in depression. In a diverse sample of 259 early adolescents (54% female; 51% African American; Mage = 12.86 years), both peer and familial emotional victimization predicted increases in hopelessness more strongly among adolescents with weaker future orientations than among those with stronger future orientations. Further, moderated mediation analyses revealed that hopelessness significantly mediated the relationship between emotional victimization and increases in depressive symptoms more strongly among adolescents with weaker orientations towards the future compared to those with stronger future orientations. These findings indicate that adolescents’ tendency to think about the future may impact whether emotional victimization induces hopelessness and ultimately depressive symptoms during early adolescence. Results have important implications regarding intervention and prevention of depression during the critical developmental period of adolescence. PMID:25052625

Toward a developmentally informed approach to parenting interventions: Seeking hidden effects.

PubMed

Brock, Rebecca L; Kochanska, Grazyna

2016-05-01

Drawing from developmental psychology and psychopathology, we propose a new, developmentally informed approach to parenting interventions that focuses on elucidating changes in the unfolding developmental process between the parent and child. We present data from 186 low-income mothers of toddlers, randomly assigned to a child-oriented play group or a play-as-usual group. We examined the maladaptive cascade from child difficulty to mother adversarial, negative parenting to child maladjustment, well documented in the literature. The measures incorporated multiple observations and reports. As expected, the sequence from child difficulty (pretest) to mother adversarial, negative parenting (Posttest 1, after 3-month intervention) to child maladjustment (Posttest 2, 6 months later) was present in the play-as-usual group, but absent, or defused, in the child-oriented play group. The findings are consistent with a view of intervention presumably enhancing the mother-child relationship, which in turn served to moderate future mother-child dynamics, altering its otherwise anticipated negative trajectory. A closer examination of the cascade revealed that, at Posttest 1, mothers in the play-as-usual group engaged in more adversarial, negative parenting (controlling for pretest) than did mothers in the child-oriented play group when their children were of high difficulty. The intervention appears to exert its primary influence on the cascade by weakening the link between child difficulty and maternal adversarial, negative parenting.

We report electric field induced increase of spin orientation of negatively charged excitons (trions) localized in n -type GaAs/AlGaAs quantum well. Under resonant excitation of free neutral heavy-hole excitons, the polarization of trions increases dramatically with electrical injection of electrons. The polarization enhancement correlates strongly with trion/exciton luminescence intensity ratio. This effect results from a very efficient trapping of free neutral excitons by the quantum well interfacial fluctuations (“natural” quantum dots) containing resident electrons.

To explore the complex relationships between nurses' personal resources, job satisfaction and 'customer' (patient) orientation. Previous research has shown that nursing is highly intensive, emotionally charged work, which affects nurses' job performance and their customer orientation as well as patient or 'customer' satisfaction. This study contributes to the literature by examining how nurses' personal resources relate to their personal satisfaction and customer orientation and the relationships between them. Specifically, this study explores the effects of two facets of emotional labour (deep acting and surface acting), empathic concern, self-efficacy and emotional exhaustion on personal job satisfaction and customer orientation. We also test the moderating effects of inauthenticity and emotional contagion. A quantitative survey. Data were collected through a self-completion questionnaire administered to a sample of 159 Australian nurses, in a public teaching hospital, in 2010. The data were analysed using Partial Least Square analysis. Partial Least Square analysis indicates that the final model is a good fit to the data (Goodness of Fit = 0.51). Deep acting and surface acting have different effects (positive and negative) on job satisfaction and 'customer' orientation, self-efficacy has a positive effect on both and emotional exhaustion has a positive effect on customer orientation and a negative effect on job satisfaction. The moderating effects of emotional contagion and empathic concern, in the final model, are discussed. Understanding the complex interactions between personal resources, job satisfaction and customer orientation helps to increase service providers' (nurses in this study) personal satisfaction and 'customer' orientation particularly in difficult contexts. © 2013 John Wiley & Sons Ltd.

Image classification independent of orientation and scale

1998-04-01

The recognition of targets independently of orientation has become fairly well developed in recent years for in-plane rotation. The out-of-plane rotation problem is much less advanced. When both out-of-plane rotations and changes of scale are present, the problem becomes very difficult. In this paper we describe our research on the combined out-of- plane rotation problem and the scale invariance problem. The rotations were limited to rotations about an axis perpendicular to the line of sight. The objects to be classified were three kinds of military vehicles. The inputs used were infrared imagery and photographs. We used a variation of a method proposed by Neiberg and Casasent, where a neural network is trained with a subset of the database and a minimum distances from lines in feature space are used for classification instead of nearest neighbors. Each line in the feature space corresponds to one class of objects, and points on one line correspond to different orientations of the same target. We found that the training samples needed to be closer for some orientations than for others, and that the most difficult orientations are where the target is head-on to the observer. By means of some additional training of the neural network, we were able to achieve 100% correct classification for 360 degree rotation and a range of scales over a factor of five.

Background Prescription opioid use disorder and overdose have risen substantially in the U.S. Primary care physicians are critical to many ongoing and proposed efforts to address the prescription opioid epidemic. Yet, little is known about their attitudes and beliefs surrounding this issue. This study aimed to determine primary care physicians’ perceptions of the seriousness of the problem, its causes, groups responsible for addressing it, attitudes toward individuals with prescription opioid use disorder, beliefs about the effectiveness of addiction treatments, and support for various policies. Methods We conducted a national web-based survey in 2014 among 1,010 primary care physicians. We gauged responses to attitude and belief items on 7-point Likert scales. We examined the proportion agreeing with each statement, and whether responses differed among physicians prescribing higher and lower volumes of opioids. Results Respondents largely attributed the causes of prescription opioid use disorder to individual-oriented factors and certain physician-oriented factors, and believed that individuals with prescription opioid use disorder and physicians were primarily responsible for addressing the problem. Negative attitudes toward people with prescription opioid use disorder were prevalent, but a majority believed that treatment could be effective. There was majority support for all measured policies, with the highest levels of support for policies to monitor prescribing among patients potentially at risk for an opioid use disorder and to improve physician education and training. Conclusions Given strong endorsement of recommended policies, physician support could be leveraged to advance efforts to curb prescription opioid use disorder and overdose. PMID:27261154

Measurements HPSS, CD4, hemoglobin A1c (HbA1c), and number of hospitalizations in the previous year and Emergency Department (ED) visits in the previous 6 months. Results Administration time for the HPSS ranged from 5 to 10 minutes. Cronbach’s alpha for the total HPSS was 0.86 and 0.89 for HIV and DM, respectively. Higher total scores (better problem solving) were associated with higher CD4 and fewer hospitalizations in HIV and lower HbA1c and fewer ED visits in DM. Health Problem-Solving Scale subscales representing negative problem-solving approaches were consistently associated with more hospitalizations (HIV, DM) and ED visits (DM). Conclusions The HPSS may identify problem-solving difficulties with disease self-management and assess effectiveness of interventions targeting patient decision making in self-care. PMID:17443373

Object oriented development of engineering software using CLIPS

Engineering applications involve numeric complexity and manipulations of a large amount of data. Traditionally, numeric computation has been the concern in developing an engineering software. As engineering application software became larger and more complex, management of resources such as data, rather than the numeric complexity, has become the major software design problem. Object oriented design and implementation methodologies can improve the reliability, flexibility, and maintainability of the resulting software; however, some tasks are better solved with the traditional procedural paradigm. The C Language Integrated Production System (CLIPS), with deffunction and defgeneric constructs, supports the procedural paradigm. The natural blending of object oriented and procedural paradigms has been cited as the reason for the popularity of the C++ language. The CLIPS Object Oriented Language's (COOL) object oriented features are more versatile than C++'s. A software design methodology based on object oriented and procedural approaches appropriate for engineering software, and to be implemented in CLIPS was outlined. A method for sensor placement for Space Station Freedom is being implemented in COOL as a sample problem.

Identity distress involves intense or prolonged upset or worry about personal identity issues including long-term goals, career choice, friendships, sexual orientation and behavior, religion, values and beliefs, and group loyalties. Research suggests that trauma exposure and subsequent PTSD symptoms may negatively impact identity development and psychological adjustment. However, little is known about their specific associations with identity distress and internalizing problems among disaster-exposed adolescents. The purpose of this study was to examine these relationships in a sample of 325 adolescents (60% female; 89% African American) who experienced a major natural disaster and its aftermath. The results indicated that identity distress was positively associated with age, hurricane exposure, PTSD symptoms, and internalizing problems. Linear regression analyses also showed that identity distress was uniquely associated with internalizing symptoms and that there was an indirect effect of hurricane exposure on identity distress via PTSD symptoms. Finally, PTSD symptoms moderated the link between identity distress and internalizing symptoms, with a significant positive slope found for youth with more PTSD symptoms. Findings were generally consistent with previous work and predictions, and add to the extant knowledge about identity distress by providing data on the linkages between disaster exposure, posttraumatic stress and internalizing problems in adolescents.

Detection and Rectification of Distorted Fingerprints.

Elastic distortion of fingerprints is one of the major causes for false non-match. While this problem affects all fingerprint recognition applications, it is especially dangerous in negative recognition applications, such as watchlist and deduplication applications. In such applications, malicious users may purposely distort their fingerprints to evade identification. In this paper, we proposed novel algorithms to detect and rectify skin distortion based on a single fingerprint image. Distortion detection is viewed as a two-class classification problem, for which the registered ridge orientation map and period map of a fingerprint are used as the feature vector and a SVM classifier is trained to perform the classification task. Distortion rectification (or equivalently distortion field estimation) is viewed as a regression problem, where the input is a distorted fingerprint and the output is the distortion field. To solve this problem, a database (called reference database) of various distorted reference fingerprints and corresponding distortion fields is built in the offline stage, and then in the online stage, the nearest neighbor of the input fingerprint is found in the reference database and the corresponding distortion field is used to transform the input fingerprint into a normal one. Promising results have been obtained on three databases containing many distorted fingerprints, namely FVC2004 DB1, Tsinghua Distorted Fingerprint database, and the NIST SD27 latent fingerprint database.

Background: This study aimed to assess driving behavior of Iranian drivers based on their coping styles (problem-oriented, emotion-oriented, and avoiding). Methods: This study was conducted on 610 drivers divided into four different groups. The drivers’ behaviors and coping styles were evaluated using driver behavior questionnaire (DBQ) and coping inventory for stressful situations. Results: The results showed a significant difference among the three coping styles regarding the mean scores of DBQ dimensions (P < 0.001). In addition, the emotion-oriented drivers obtained higher mean scores compared to those with other coping styles. Conclusions: It can be concluded that emotion-oriented drivers were more susceptible to crashes compared to those with problem-solving and avoidance coping styles. PMID:28757929

The present study examined variables related to the quality of the therapeutic alliance in out-patients with schizophrenia. We expected recovery orientation and insight to be positively, and self-stigma to be negatively associated with a good therapeutic alliance. We expected these associations to be independent from age, clinical symptoms (i.e. positive and negative symptoms, depression), and more general aspects of relationship building like avoidant attachment style and the duration of treatment by the current therapist. The study included 156 participants with DSM-IV diagnoses of schizophrenia or schizoaffective disorder in the maintenance phase of treatment. Therapeutic alliance, recovery orientation, self-stigma, insight, adult attachment style, and depression were assessed by self-report. Symptoms were rated by interviewers. Hierarchical multiple regressions revealed that more recovery orientation, less self-stigma, and more insight independently were associated with a better quality of the therapeutic alliance. Clinical symptoms, adult attachment style, age, and the duration of treatment by current therapist were unrelated to the quality of the therapeutic alliance. Low recovery orientation and increased self-stigma might undermine the therapeutic alliance in schizophrenia beyond the detrimental effect of poor insight. Therefore in clinical settings, besides enhancing insight, recovery orientation, and self-stigma should be addressed. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Pushing through evolution? Incidence and fight records of left-oriented fighters in professional boxing history.

PubMed

Loffing, Florian; Hagemann, Norbert

2015-05-01

The fighting hypothesis proposes that left-oriented athletes enjoy a negative frequency-dependent advantage in combat sports such as boxing. Supporting evidence, however, is restricted to cross-sectional frequency data from small samples. Here, we examined the incidence and fight records of 2,403 left- and right-oriented fighters who were listed in the annual ratings of professional boxing from 1924 to 2012. Unexpectedly, left-oriented boxers were overrepresented in no more than 7 of the 89 years considered, their percentages varied up to 30% and increased over the entire period, and frequencies varied substantially between weight divisions. In support of the fighting hypothesis, lose-win ratios indicated larger fighting strength in left- compared to right-oriented boxers, which, however, was not reflected in different proportions of wins and losses by knockout. Our findings are partly consistent with an assumed left-oriented fighters' advantage in combat sports. Such advantage could be explained by negative frequency-dependent selection mechanisms; however, our study also revealed potential limits of the fighting hypothesis such that alternative explanations cannot be fully excluded. We propose that interference by factors not related to performance could also limit the suitability of data from elite sporting competition for testing evolutionary models of human handedness.

Integration of object-oriented knowledge representation with the CLIPS rule based system

Logie, David S.; Kamil, Hasan

1990-01-01

The paper describes a portion of the work aimed at developing an integrated, knowledge based environment for the development of engineering-oriented applications. An Object Representation Language (ORL) was implemented in C++ which is used to build and modify an object-oriented knowledge base. The ORL was designed in such a way so as to be easily integrated with other representation schemes that could effectively reason with the object base. Specifically, the integration of the ORL with the rule based system C Language Production Systems (CLIPS), developed at the NASA Johnson Space Center, will be discussed. The object-oriented knowledge representation provides a natural means of representing problem data as a collection of related objects. Objects are comprised of descriptive properties and interrelationships. The object-oriented model promotes efficient handling of the problem data by allowing knowledge to be encapsulated in objects. Data is inherited through an object network via the relationship links. Together, the two schemes complement each other in that the object-oriented approach efficiently handles problem data while the rule based knowledge is used to simulate the reasoning process. Alone, the object based knowledge is little more than an object-oriented data storage scheme; however, the CLIPS inference engine adds the mechanism to directly and automatically reason with that knowledge. In this hybrid scheme, the expert system dynamically queries for data and can modify the object base with complete access to all the functionality of the ORL from rules.

Using Balanced Time Perspective to Explain Well-Being and Planning in Retirement.

Mooney, Anna; Earl, Joanne K; Mooney, Carl H; Bateman, Hazel

2017-01-01

The notion of whether people focus on the past, present or future, and how it shapes their behavior is known as Time Perspective. Fundamental to the work of two of its earliest proponents, Zimbardo and Boyd (2008), was the concept of balanced time perspective and its relationship to wellness. A person with balanced time perspective can be expected to have a flexible temporal focus of mostly positive orientations (past-positive, present-hedonistic, and future) and much less negative orientations (past-negative and present-fatalistic). This study measured deviation from balanced time perspective (DBTP: Zhang et al., 2013) in a sample of 243 mature adults aged 45 to 91 years and explored relationships to Retirement Planning, Depression, Anxiety, Stress, Positive Mood, and Negative Mood. Results indicate that DBTP accounts for unexplained variance in the outcome measures even after controlling for demographic variables. DBTP was negatively related to Retirement Planning and Positive Mood and positively related to Depression, Anxiety, Stress, and Negative Mood. Theoretical and practical implications regarding balanced time perspective are discussed.

The report discusses the orientation tracking control problem for a kinematically redundant, autonomous manipulator moving in a three dimensional workspace. The orientation error is derived using the normalized quaternion error method of Ickes, the Luh, Walker, and Paul error method, and a method suggested here utilizing the Rodrigues parameters, all of which are expressed in terms of normalized quaternions. The analytical time derivatives of the orientation errors are determined. The latter, along with the translational velocity error, form a dosed loop kinematic velocity model of the manipulator using normalized quaternion and translational position feedback. An analysis of the singularities associatedmore » with expressing the models in a form suitable for solving the inverse kinematics problem is given. Two redundancy resolution algorithms originally developed using an open loop kinematic velocity model of the manipulator are extended to properly take into account the orientation tracking control problem. This report furnishes the necessary mathematical framework required prior to experimental implementation of the orientation tracking control schemes on the seven axis CESARm research manipulator or on the seven-axis Robotics Research K1207i dexterous manipulator, the latter of which is to be delivered to the Oak Ridge National Laboratory in 1993.« less

A knowledge-based, concept-oriented view generation system for clinical data.

PubMed

Zeng, Q; Cimino, J J

2001-04-01

Information overload is a well-known problem for clinicians who must review large amounts of data in patient records. Concept-oriented views, which organize patient data around clinical concepts such as diagnostic strategies and therapeutic goals, may offer a solution to the problem of information overload. However, although concept-oriented views are desirable, they are difficult to create and maintain. We have developed a general-purpose, knowledge-based approach to the generation of concept-oriented views and have developed a system to test our approach. The system creates concept-oriented views through automated identification of relevant patient data. The knowledge in the system is represented by both a semantic network and rules. The key relevant data identification function is accomplished by a rule-based traversal of the semantic network. This paper focuses on the design and implementation of the system; an evaluation of the system is reported separately.

When choice matters: task-dependent memory effects in older adulthood.

PubMed

Depping, Miriam K; Freund, Alexandra M

2013-12-01

As goal orientation shifts across adulthood from a primary orientation toward gains to an increased importance of the prevention of losses, older adults' information processing may be particularly sensitive to potential losses if there is a possibility of avoiding them. In line with these motivational changes, we expected older adults to remember more loss-related information when choosing between 2 options than when not having to make a decision and when compared with younger adults. Using an incidental memory paradigm, we asked younger and older adults to recall as much information as possible of 2 previously presented hypothetical travel packages (Experiment 1) or 2 hospitals (Experiment 2) containing positive (gain-related), negative (loss-related), and neutral information in either a decision or a control condition (evaluating the readability of the texts). Experiment 1 showed that older adults remembered more negative information than younger adults and more negative than positive information in the choice but not in the control condition. Experiment 2 followed the same procedure using a choice between 2 hospitals for minor surgery. This choice was assumed to trigger a stronger orientation toward the prevention of losses than the choice between travel packages. As expected, in this situation, both age groups remembered more negative information relative to neutral and positive information regardless of the condition (choice vs. control). Importantly, older adults remembered more negative information in the choice condition compared with younger adults. Taken together, results suggest that the processing of decision-relevant information promotes a stronger focus on negative information in older adults.

The crude divorce rate has been increasing steadily for over a decade in China. Consequently, more and more children have to face the challenge of growing up in single parent families. The current study investigated the mediating effects of problem-oriented and emotion-oriented coping on the relationship between parental attachment and psychological resilience among a sample of Chinese adolescents from single parent families and intact families. Participants were 975 high school students (44.30% males; aged 15-19 years, M = 16.32 years, SD = 0.74), 871 from intact families and 104 from single parent families. Structural equation modeling showed that security in maternal attachment was positively associated with resilience through the indirect effect of reduced emotion-oriented coping among adolescents from single parent families. Among adolescents from intact families, security in maternal attachment was both directly associated with resilience and indirectly through enhanced problem-oriented and reduced emotion-oriented coping. Security in paternal attachment was associated with resilience both directly and indirectly through enhanced problem-oriented coping as well among those from intact families. Female adolescents exhibited significantly lower levels of resilience than male adolescents did regardless of the marital status of their parents. Limitations and suggestions for future research are discussed.

To assess the mental health and behavioral problems of children in institutional placements in Jordan to inform understanding of current needs, and to explore the effects of placement change on functioning and staff perceptions of goodness-of-fit. An assessment was completed of 134 children between 1.5-12 years-of-age residing in Jordanian orphanages. The Child Behavior Checklist was used to assess prevalence rates of problems across externalizing and internalizing behavior and DSM-IV oriented subscales. Also included was caregiver perceived goodness-of-fit with each child, caregiving behavior, and two placement change-clock variables; an adjustment clock measuring time since last move, and an anticipation clock measuring time to next move. 28% were in the clinical range for the internalizing domain on the CBCL, and 22% for the externalizing domain. The children also exhibited high levels of clinical range social problems, affective disorder, pervasive developmental disorder, and conduct problems. Internalizing problems were found to decrease with time in placement as children adjust to a prior move, whereas externalizing problems increased as the time to their next age-triggered move drew closer, highlighting the anticipatory effects of change. Both behavioral problems and the change clocks were predictive of staff perceptions of goodness-of-fit with the children under their care. These findings add to the evidence demonstrating the negative effects of orphanage rearing, and highlight the importance of the association between behavioral problems and child-caregiver relationship pathways including the timing of placement disruptions and staff perceptions of goodness-of-fit.

Differential Associations of UPPS-P Impulsivity Traits With Alcohol Problems.

PubMed

McCarty, Kayleigh N; Morris, David H; Hatz, Laura E; McCarthy, Denis M

2017-07-01

The UPPS-P model posits that impulsivity comprises five factors: positive urgency, negative urgency, lack of planning, lack of perseverance, and sensation seeking. Negative and positive urgency are the traits most consistently associated with alcohol problems. However, previous work has examined alcohol problems either individually or in the aggregate, rather than examining multiple problem domains simultaneously. Recent work has also questioned the utility of distinguishing between positive and negative urgency, as this distinction did not meaningfully differ in predicting domains of psychopathology. The aims of this study were to address these issues by (a) testing unique associations of UPPS-P with specific domains of alcohol problems and (b) determining the utility of distinguishing between positive and negative urgency as risk factors for specific alcohol problems. Associations between UPPS-P traits and alcohol problem domains were examined in two cross-sectional data sets using negative binomial regression models. In both samples, negative urgency was associated with social/interpersonal, self-perception, risky behaviors, and blackout drinking problems. Positive urgency was associated with academic/occupational and physiological dependence problems. Both urgency traits were associated with impaired control and self-care problems. Associations for other UPPS-P traits did not replicate across samples. Results indicate that negative and positive urgency have differential associations with alcohol problem domains. Results also suggest a distinction between the type of alcohol problems associated with these traits-negative urgency was associated with problems experienced during a drinking episode, whereas positive urgency was associated with alcohol problems that result from longer-term drinking trends.

Problem-Oriented Corporate Knowledge Base Models on the Case-Based Reasoning Approach Basis

NASA Astrophysics Data System (ADS)

Gluhih, I. N.; Akhmadulin, R. K.

2017-07-01

One of the urgent directions of efficiency enhancement of production processes and enterprises activities management is creation and use of corporate knowledge bases. The article suggests a concept of problem-oriented corporate knowledge bases (PO CKB), in which knowledge is arranged around possible problem situations and represents a tool for making and implementing decisions in such situations. For knowledge representation in PO CKB a case-based reasoning approach is encouraged to use. Under this approach, the content of a case as a knowledge base component has been defined; based on the situation tree a PO CKB knowledge model has been developed, in which the knowledge about typical situations as well as specific examples of situations and solutions have been represented. A generalized problem-oriented corporate knowledge base structural chart and possible modes of its operation have been suggested. The obtained models allow creating and using corporate knowledge bases for support of decision making and implementing, training, staff skill upgrading and analysis of the decisions taken. The universal interpretation of terms “situation” and “solution” adopted in the work allows using the suggested models to develop problem-oriented corporate knowledge bases in different subject domains. It has been suggested to use the developed models for making corporate knowledge bases of the enterprises that operate engineer systems and networks at large production facilities.

Although discrimination is a common stressor in the everyday life of immigrant youth, individuals are not equally susceptible to its adverse effects. This cross-sectional study aimed to examine whether cultural orientation preferences and impulse control (IC) moderate the association between perceived discrimination and externalizing problems among Moroccan- and Romanian-origin early adolescents in Italy. The sample included 126 Moroccan and 126 Romanian youths (46% girls, 42% first-generation) aged 11-13 years and their parents. Perceived discrimination and cultural orientations were assessed using self-report questionnaires, while IC was evaluated via a computerized version of the Iowa Gambling Task. Externalizing behaviors were assessed via parental report. Cluster analysis identified separated, assimilated, and integrated early adolescents. Regression analyses revealed that when facing discrimination, youths who endorsed separation and exhibited low levels of IC were more vulnerable to externalizing problems. In contrast, among assimilated adolescents the discrimination-externalizing difficulties link was significant at high levels of IC. Furthermore, low levels of IC were associated with more externalizing problems for Romanian, but not for Moroccan early adolescents. Findings underscore the need to consider both cultural orientation processes and early adolescents' ability to control their impulses when developing interventions aimed to reduce discrimination-related problem behaviors in immigrant youth. Implications for theory and practice are discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

The relation of locus-of-control orientation and task structure to problem-solving performance of sixth-grade student pairs

NASA Astrophysics Data System (ADS)

Main, June Dewey; Budd Rowe, Mary

This study investigated the relationship of locus-of-control orientations and task structure to the science problem-solving performance of 100 same-sex, sixth-grade student pairs. Pairs performed a four-variable problem-solving task, racing cylinders down a ramp in a series of trials to determine the 3 fastest of 18 different cylinders. The task was completed in one of two treatment conditions: the structured condition with moderate cuing and the unstructured condition with minimal cuing. Pairs completed an after-task assessment, predicting the results of proposed cylinder races, to measure the ability to understand and apply task concepts. Overall conclusions were: (1) There was no relationship between locus-of-control orientation and effectiveness of problem-solving strategy; (2) internality was significantly related to higher accuracy on task solutions and on after-task predictions; (3) there was no significant relationship between task structure and effectiveness of problem-solving strategy; (4) solutions to the task were more accurate in the unstructured task condition; (5) internality related to more accurate solutions in the unstructured task condition.

African American youth, particularly those from single-mother homes, are overrepresented in statistics on externalizing problems. The family is a central context in which to understand externalizing problems; however, reliance on variable-oriented approaches to the study of parenting, which originate from work with intact, middle-income, European American families, may obscure important information regarding variability in parenting styles among African American single mothers, and in turn, variability in youth outcomes as well. The current study demonstrated that within African American single-mother families: (a) a person-, rather than variable-, oriented approach to measuring parenting style may further elucidate variability; (b) socioeconomic status may provide 1 context within which to understanding variability in parenting style; and (c) 1 marker of socioeconomic status, income, and parenting style may each explain variability in youth externalizing problems; however, the interaction between income and parenting style was not significant. Findings have potential implications for better understanding the specific contexts in which externalizing problems may be most likely to occur within this at-risk and underserved group.

This study addressed the issue of disclosing HIV status and sexual orientation, and explored the consequences of such disclosures among HIV-positive men who have sex with men (MSM) in China. In-depth individual interviews were conducted with 37 HIV-positive MSM. Of these participants, 3 (8.1%) disclosed neither their HIV status nor their sexual orientation to anyone; 24 (64.9%) voluntarily disclosed both their HIV-positive status and their sexual orientation; 7 (18.9%) voluntarily disclosed their HIV status only, and 3 (8.1%) involuntarily disclosed their HIV status and sexual orientation. Parents, partners, siblings and close friends were the most common disclosure targets. HIV-positive MSM were less likely to disclose their sexual orientation than their HIV status. The positive consequences of disclosure included receiving support, acquiring family care, reducing stress, improving mood and developing more positive values and beliefs. The negative consequences included the participants' perception of rejection and stigma toward themselves and their families. However, the stigma mainly comes from "outsiders" rather than family members and close friends. We did not find any differences with respect to consequences between participants who disclosed their HIV status only and those who disclosed both their HIV status and sexual orientation. In conclusion, partners, siblings and friends were main disclosure targets, and HIV positive MSM preferred to disclose their HIV serostatus than their sexual orientation. Voluntarily disclosing one's HIV status to significant others resulted in more positive consequences than negative consequences. Theses results were informative for developing mental health and coping interventions.

The aim of the present study was to investigate whether psycho-social variables, for example social support and task- and emotion-oriented coping would predict psychological and physical well being among young adults with diabetes. Participants were 56 individuals in their twenties suffering from type 1 diabetes. Response rate was 78%. The participants came from the whole of Iceland, 64.3% from the Greater Reykjavík area and 33.9% from rural areas. One participant did not indicate his place of residence. Self-assessment scales were used to assess depression, anxiety, task-, avoidance- and emotion-oriented coping, social support and problems relating to diabetes. Additional information was obtained from patients' records concerning the results of blood glucose measurements (HbA1c). Good social support was related to less anxiety and depression and to less self-reported problems related to having diabetes. Emotion-oriented coping was related to not feeling well and task- oriented coping to feeling better. No relationship was found between psychosocial variables and blood glucose measurements and a limited relationship between self-reported problems related to having diabetes and these measurements. Social support and coping are strongly related to measurements of depression, anxiety and problems related to having diabetes in the present age group. The results indicate that it is very important to teach and strengthen usage, as possible, of task-oriented coping instead of emotion-oriented coping. The results also indicate that social support is highly important for young adults with diabetes type 1. It is clear that friends and family have to be more involved in the treatment and also more educated about the disease and the importance of giving the right kind of support.

The problem based teaching (PBT) has been the main approach to the training in the universities o the world. Combined with the team oriented learning method, PBT will become the method available to the education in medical universities. In the paper, based on the common questions in teaching Jingluo Shuxue Xue (Science of Meridian and Acupoint), the concepts and characters of PBT and the team oriented learning method were analyzed. The implementation steps of PBT were set up in reference to the team oriented learning method. By quoting the original text in Beiji Qianjin Yaofang (Essential recipes for emergent use worth a thousand gold), the case analysis on "the thirteen devil points" was established with PBT.

The clinical outcomes of patients who have undergone total pelvic exenteration (TPE) for locally advanced primary colorectal cancer have not been satisfactory. For the last 13 years, we have performed layer-oriented, en bloc resection of tumor for which TPE is indicated, in the hope of improving postoperative outcomes. The clinical outcomes of these cases were retrospectively analyzed. A total of 54 patients who underwent TPE from 1986 to 2013 were retrospectively analyzed. Since 2002, a layer-oriented removal for clinical T4 colorectal cancer, as in T3 or less invasive tumors removed by total mesorectal excision, was applied to 23 cases for which TPE was indicated. Postoperative mortality, morbidity, overall survival (OS), and disease-free survival (DFS) were evaluated. On univariate analysis, good postoperative OS and DFS were associated with the layer-oriented operative maneuver, blood loss less than 2000 mL, negative nodal metastasis, and no preoperative radiation therapy. Male sex was the marginal determinant correlated with good OS and DFS. Depth of invasion to T3 was the marginal determinant correlated with good DFS. On multivariate analysis using the 4 factors identified on univariate analyses, the layer-oriented operative procedure was a significant determinant for both good OS and DFS, together with negative nodal metastases. Postoperative mortality and morbidity in the layer-oriented excision were acceptable. For primary colorectal cancers for which TPE is indicated, layer-oriented excision was a safe and effective procedure, and it may be recommended as one of the standard surgical approaches in TPE.

A Feature Selection Method Based on Fisher's Discriminant Ratio for Text Sentiment Classification

Wang, Suge; Li, Deyu; Wei, Yingjie; Li, Hongxia

With the rapid growth of e-commerce, product reviews on the Web have become an important information source for customers' decision making when they intend to buy some product. As the reviews are often too many for customers to go through, how to automatically classify them into different sentiment orientation categories (i.e. positive/negative) has become a research problem. In this paper, based on Fisher's discriminant ratio, an effective feature selection method is proposed for product review text sentiment classification. In order to validate the validity of the proposed method, we compared it with other methods respectively based on information gain and mutual information while support vector machine is adopted as the classifier. In this paper, 6 subexperiments are conducted by combining different feature selection methods with 2 kinds of candidate feature sets. Under 1006 review documents of cars, the experimental results indicate that the Fisher's discriminant ratio based on word frequency estimation has the best performance with F value 83.3% while the candidate features are the words which appear in both positive and negative texts.

Adolescents of the USA National Longitudinal Lesbian Family Study: can family characteristics counteract the negative effects of stigmatization?

This investigation examines the impact of homophobic stigmatization on the well-being of 17-year-old adolescents who were conceived through donor insemination and whose mothers enrolled before they were born in the largest, longest-running, prospective study of lesbian families, with a 93% retention rate to date. The data for the current report were collected through questionnaires completed by the adolescents and their mothers. The adolescents (39 girls and 39 boys) were queried about family connection and compatibility. They were also asked to indicate if they had experienced discrimination based on their mothers' sexual orientation. Adolescent well-being was assessed through the parental report of the Child Behavior Checklist/6-18. Forty-one percent of the adolescents had experienced stigmatization based on homophobia. Hierarchical, multiple-regression analyses revealed that stigmatization was associated with more problem behavior in these adolescents, but that family compatibility neutralized this negative influence. The results indicate that adolescents who have close, positive relationships with their lesbian mothers demonstrate resilience in response to stigmatization. 2010 © FPI, Inc.

The aim of this study was to develop a Self-Talk Inventory for young adults. This inventory consisted of two scales. The Negative Self-Talk Scale included three categories of self-talk (depressive, anxious, and angry thoughts) and the Positive Self-Talk Scale, three categories (minimization, positive orientation, and coping self-instructions). Participants were 982 undergraduate students (Mean age = 20.35 years, SD = 2.16). They completed the self-talk scales together with the following scales to measure symptoms of affective disorders: the Center for Epidemiological Studies Depression Scale (CES-D), the State-Trait Anxiety Inventory (STAI), and the State-Trait Anger Expression Inventory (STAXI-T). Factor analyses confirmed the hypothesized structure for the Self-Talk Inventory. The relations between self-talk and symptoms of affective disorders (depression, anxiety, and anger) were also evaluated. In general, states-of-mind -SOM- ratios and negative cognitions showed a greater association with psychological symptoms than did positive cognitions. Results concerning the cognitive characteristics of depression, anxiety, and anger were mixed and partially supported the cognitive content specificity theory.

Expanding the scope of psychiatric nursing practice: devaluing the essence of psychiatric nursing?

PubMed

Hogan, Beverly Kay

2012-09-01

Psychiatric Nurse Practitioners are quickly becoming sought after employees, especially in public mental health systems where a shrinking number of psychiatrists necessitate alternate access to prescribers. In addition, new guidelines necessitate greater attention to the follow up and monitoring of the medical problems of psychiatric patients. These events are occurring in the midst of declining reimbursement and rising litigation concerns in psychiatry. At the same time there is an increased focus on a recovery orientation to psychiatry alongside the primacy of psychotropic medicine as the most cost effective treatment, which can become competing aims for practitioners. It is important for psychiatric nurses and psychiatric nurse practitioners to consider how these opportunities might also have a negative impact on the core foundation of psychiatric nursing.

2015-01-01

Sleep-temperament associations have not yet been examined among university students, despite awareness of the high incidence of sleep problems in this population. The present study was conducted (a) to examine whether sleep quality was associated with temperament among university-attending young adults and (b) to determine whether particular components of sleep quality were differentially associated with temperament. University students completed questionnaires designed to assess sleep quality and temperament. Poor sleep quality was associated with increased negative affect and orienting sensitivity as well as decreased effortful control; regression analyses revealed differential associations between components of nighttime sleep quality and temperament ratings. The presented study reveals conceptual continuity in sleep-temperament relations from infancy to young adulthood and highlights important avenues for future research.

The contig orientation problem, which we formally define as the MAX-DIR problem, has at times been addressed cursorily and at times using various heuristics. In setting forth a linear-time reduction from the MAX-CUT problem to the MAX-DIR problem, we prove the latter is NP-complete. We compare the relative performance of a novel greedy approach with several other heuristic solutions. Our results suggest that our greedy heuristic algorithm not only works well but also outperforms the other algorithms due to the nature of scaffold graphs. Our results also demonstrate a novel method for identifying inverted repeats and inversion variants, both of which contradict the basic single-orientation assumption. Such inversions have previously been noted as being difficult to detect and are directly involved in the genetic mechanisms of several diseases. http://bioresearch.byu.edu/scaffoldscaffolder. paulmbodily@gmail.com Supplementary data are available at Bioinformatics online. © The Author 2015.

2016-01-01

Previous studies conducted in Western societies showed that instructors’ beliefs about intellectual ability affected their attitudes toward students. However, in many East Asian societies influenced by Confucian culture, teachers not only hold beliefs of ability but also two kinds of beliefs about effort: obligation-oriented belief (i.e., believing that effort-making is a student’s role obligation) and improvement-oriented belief (i.e., believing that effort can conquer the limitations of one’s ability). This study aimed to investigate the relationships between teachers’ effort beliefs and their attitudes toward favoritism, praise, and expectations toward struggling and smart students. The participants were 151 Taiwanese high-school teachers. Results of Structure Equation Modeling showed that (1) teachers’ obligation-oriented belief about effort was positively correlated with their favoritism, praise, short-term and long-term expectations of struggling students, but negatively correlated with their favoritism and praise of smart students, (2) teachers’ improvement-orientated belief about effort was negatively correlated with their short-term expectation of smart students and favoritism of struggling students, but positively correlated with their praise of smart students, and (3) the entity theory of intelligence was negatively correlated with favoritism and praise of struggling students, but positively correlated with favoritism of smart students. The theoretical and cultural implications are discussed. PMID:27683565

A shared computer-based problem-oriented patient record for the primary care team.

PubMed

Linnarsson, R; Nordgren, K

1995-01-01

1. INTRODUCTION. A computer-based patient record (CPR) system, Swedestar, has been developed for use in primary health care. The principal aim of the system is to support continuous quality improvement through improved information handling, improved decision-making, and improved procedures for quality assurance. The Swedestar system has evolved during a ten-year period beginning in 1984. 2. SYSTEM DESIGN. The design philosophy is based on the following key factors: a shared, problem-oriented patient record; structured data entry based on an extensive controlled vocabulary; advanced search and query functions, where the query language has the most important role; integrated decision support for drug prescribing and care protocols and guidelines; integrated procedures for quality assurance. 3. A SHARED PROBLEM-ORIENTED PATIENT RECORD. The core of the CPR system is the problem-oriented patient record. All problems of one patient, recorded by different members of the care team, are displayed on the problem list. Starting from this list, a problem follow-up can be made, one problem at a time or for several problems simultaneously. Thus, it is possible to get an integrated view, across provider categories, of those problems of one patient that belong together. This shared problem-oriented patient record provides an important basis for the primary care team work. 4. INTEGRATED DECISION SUPPORT. The decision support of the system includes a drug prescribing module and a care protocol module. The drug prescribing module is integrated with the patient records and includes an on-line check of the patient's medication list for potential interactions and data-driven reminders concerning major drug problems. Care protocols have been developed for the most common chronic diseases, such as asthma, diabetes, and hypertension. The patient records can be automatically checked according to the care protocols. 5. PRACTICAL EXPERIENCE. The Swedestar system has been implemented in a primary care area with 30,000 inhabitants. It is being used by all the primary care team members: 15 general practitioners, 25 district nurses, and 10 physiotherapists. Several years of practical experience of the CPR system shows that it has a positive impact on quality of care on four levels: 1) improved clinical follow-up of individual patients; 2) facilitated follow-up of aggregated data such as practice activity analysis, annual reports, and clinical indicators; 3) automated medical audit; and 4) concurrent audit. Within that primary care area, quality of care has improved substantially in several aspects due to the use of the CPR system [1].

2018-02-01

In the present study, we examined from a longitudinal perspective the relationship between parental (both maternal and paternal) psychological control, perceived peer support, and negative eating attitudes and behaviors, focusing on the moderating role that perceived peer support may play in the relationship between parental psychological control in early adolescence and negative eating attitudes and behaviors in late adolescence. In Wave 1, participants were 507 adolescents (249 boys and 258 girls) aged from 14 to 15 years (M = 14.76; SD = 0.63). Three years later (Wave 2), the same adolescents participated again in the study (M = 17.88 years; SD = 0.57). Regression analyses displayed that paternal, but not maternal, achievement-oriented psychological control during early adolescence positively predicted negative eating attitudes and behaviors in late adolescence, whereas perceived peer support negatively predicted negative eating attitudes and behaviors. Results also showed a moderator effect of perceived peer support in the relationship between father's psychological control and negative eating attitudes and behaviors, such that at higher levels of paternal achievement-oriented psychological control, negative eating attitudes and behaviors tended to be higher when perceived peer support was low and to be lower when perceived peer support was high.

It has been well-established that men outperform women on some spatial tasks. The tools commonly used to demonstrate this difference (e.g. The Mental Rotations Task) typically involve problems and solutions that are presented in a context devoid of referents. The study presented here assessed whether the addition of referents (or "landmarks") would attenuate the well-established sex difference on the judgment of line orientation task (JLOT). Three versions of the JLOT were presented in a within design. The first iteration contained the original JLOT (JLOT 1). JLOT 2 contained three "landmarks" or referents and JLOT 3 contained only one landmark. The sex difference on JLOT 1 was completely negated by the addition of three landmarks on JLOT 2 or the addition of one landmark on JLOT3. In addition, salivary testosterone was measured. In men, gains in performance on the JLOT due to the addition of landmarks were positively correlated with testosterone levels. This suggests that men with the highest testosterone levels benefited the most from the addition of landmarks. These data help to highlight different strategies used by men and women to solve spatial tasks. Copyright © 2011 Elsevier Inc. All rights reserved.

Preliminary Development of an Object-Oriented Optimization Tool

NASA Technical Reports Server (NTRS)

Pak, Chan-gi

2011-01-01

The National Aeronautics and Space Administration Dryden Flight Research Center has developed a FORTRAN-based object-oriented optimization (O3) tool that leverages existing tools and practices and allows easy integration and adoption of new state-of-the-art software. The object-oriented framework can integrate the analysis codes for multiple disciplines, as opposed to relying on one code to perform analysis for all disciplines. Optimization can thus take place within each discipline module, or in a loop between the central executive module and the discipline modules, or both. Six sample optimization problems are presented. The first four sample problems are based on simple mathematical equations; the fifth and sixth problems consider a three-bar truss, which is a classical example in structural synthesis. Instructions for preparing input data for the O3 tool are presented.

There has been interest in the relationship between homosexuality, gender role and suicide risk. Though homosexuals are more likely to identify as cross-gender, research has not simultaneously examined sexual orientation and gender role in assessing suicide risk. In the current study, the unique and interactive effects of sexual orientation and gender role were assessed in regard to suicidal ideation, related psychopathology and measures of coping. 77 participants were recruited from an undergraduate psychology subject pool (n=47) or from gay, lesbian and transgender student organizations (n=30) and assessed on measures of gender role, homosexuality, and psychopathology. Consistent with expectations, cross-gender role (i.e., personality traits associated with the opposite sex) is a unique predictor of suicidal symptoms. Moreover, gender role accounted for more of the overall variance in suicidal symptoms, positive problem orientation, peer acceptance and support, than sexual orientation. After accounting for gender role, sexual orientation contributed little to the variance in suicidal symptoms, associated pathology and problem-solving deficits. There was no support for gender role by sexual orientation interaction effects. The cross-sectional nature of the data limits statements regarding causality. Cross-gendered individuals, regardless of sexual orientation, appear to have higher risk for suicidal symptoms. Researchers and clinicians should assess gender role in evaluations of youth samples.

Objective Examine factors that mediate parent-infant relationships 12 months after positive newborn screening (NBS). Method We examined effects of infant diagnosis, parents’ perceptions of child vulnerability and child attachment, parental depression and anxiety on parent-infant feeding interactions for 131 mothers and 118 fathers of 131 infants whose NBS and diagnostics confirmed cystic fibrosis (CF, n=23), congenital hypothyroidism (CH, n=35), CF carrier status (CF-C, n=38), or healthy, normal NBS (H, n=35). Results Separate composite indicator structural equation models for mothers and fathers showed neonatal diagnosis was not associated with increased anxiety or depression. In comparison to the H group, CF group parents reported higher perceptions of child vulnerability (p< 0.001, p=0.002); and CF-C group fathers viewed their children as more attached (p=0.021). High maternal perception of child vulnerability was associated with low perceptions of child attachment (p=0.001) which was associated with task-oriented feeding behavior (p=0.016, p=0.029). Parental task-oriented feeding behavior was associated with less positive (p< 0.001, p< 0.001) and more negative interactions (p< 0.001, p= 0.001) with their infants. High paternal perception of child vulnerability was associated with negative parent interactions (p< 0.001). High parental affective involvement and verbalization was associated with high infant affective expressiveness, communicative skills, and social responsiveness (mothers’ p< 0.001, fathers’ p< 0.001). High parental negative affect and/or inconsistent and intrusive behavior was associated with infant dysregulation and irritability (mothers’ p< 0.001, fathers’ p< 0.001). Conclusion The severity of conditions identified through NBS can affect parents’ perceptions of their child’s vulnerability and attachment. Infant feeding problems in the context of chronic health conditions, like CF, could represent signs of more deeply rooted concerns regarding the parent-child relationship that merit additional clinical evaluation.

Multi-point objective-oriented sequential sampling strategy for constrained robust design

NASA Astrophysics Data System (ADS)

Zhu, Ping; Zhang, Siliang; Chen, Wei

2015-03-01

Metamodelling techniques are widely used to approximate system responses of expensive simulation models. In association with the use of metamodels, objective-oriented sequential sampling methods have been demonstrated to be effective in balancing the need for searching an optimal solution versus reducing the metamodelling uncertainty. However, existing infilling criteria are developed for deterministic problems and restricted to one sampling point in one iteration. To exploit the use of multiple samples and identify the true robust solution in fewer iterations, a multi-point objective-oriented sequential sampling strategy is proposed for constrained robust design problems. In this article, earlier development of objective-oriented sequential sampling strategy for unconstrained robust design is first extended to constrained problems. Next, a double-loop multi-point sequential sampling strategy is developed. The proposed methods are validated using two mathematical examples followed by a highly nonlinear automotive crashworthiness design example. The results show that the proposed method can mitigate the effect of both metamodelling uncertainty and design uncertainty, and identify the robust design solution more efficiently than the single-point sequential sampling approach.

This study provided a descriptive and quantitative comparative analysis of data from an assessment protocol for adolescents referred clinically for gender identity disorder (n = 192; 105 boys, 87 girls) or transvestic fetishism (n = 137, all boys). The protocol included information on demographics, behavior problems, and psychosexual measures. Gender identity disorder and transvestic fetishism youth had high rates of general behavior problems and poor peer relations. On the psychosexual measures, gender identity disorder patients had considerably greater cross-gender behavior and gender dysphoria than did transvestic fetishism youth and other control youth. Male gender identity disorder patients classified as having a nonhomosexual sexual orientation (in relation to birth sex) reported more indicators of transvestic fetishism than did male gender identity disorder patients classified as having a homosexual sexual orientation (in relation to birth sex). The percentage of transvestic fetishism youth and male gender identity disorder patients with a nonhomosexual sexual orientation self-reported similar degrees of behaviors pertaining to transvestic fetishism. Last, male and female gender identity disorder patients with a homosexual sexual orientation had more recalled cross-gender behavior during childhood and more concurrent cross-gender behavior and gender dysphoria than did patients with a nonhomosexual sexual orientation. The authors discuss the clinical utility of their assessment protocol.

Derivation of three closed loop kinematic velocity models using normalized quaternion feedback for an autonomous redundant manipulator with application to inverse kinematics

1993-04-01

The report discusses the orientation tracking control problem for a kinematically redundant, autonomous manipulator moving in a three dimensional workspace. The orientation error is derived using the normalized quaternion error method of Ickes, the Luh, Walker, and Paul error method, and a method suggested here utilizing the Rodrigues parameters, all of which are expressed in terms of normalized quaternions. The analytical time derivatives of the orientation errors are determined. The latter, along with the translational velocity error, form a dosed loop kinematic velocity model of the manipulator using normalized quaternion and translational position feedback. An analysis of the singularities associatedmore » with expressing the models in a form suitable for solving the inverse kinematics problem is given. Two redundancy resolution algorithms originally developed using an open loop kinematic velocity model of the manipulator are extended to properly take into account the orientation tracking control problem. This report furnishes the necessary mathematical framework required prior to experimental implementation of the orientation tracking control schemes on the seven axis CESARm research manipulator or on the seven-axis Robotics Research K1207i dexterous manipulator, the latter of which is to be delivered to the Oak Ridge National Laboratory in 1993.« less

Military sexual trauma, combat exposure, and negative urgency as independent predictors of PTSD and subsequent alcohol problems among OEF/OIF veterans.

This study tested a path model of relationships between military sexual trauma (MST), combat exposure, negative urgency, posttraumatic stress disorder (PTSD) symptoms, and alcohol use and related problems. The sample consisted of 86 Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) veterans who reported drinking at least one alcoholic beverage per week. PTSD mediated the relationships between MST and alcohol-related problems, negative urgency and alcohol-related problems, and combat exposure and alcohol-related problems. In addition, negative urgency had a direct effect on alcohol problems. These results indicate that MST, combat exposure, and negative urgency independently predict PTSD symptoms and PTSD symptoms mediate their relationship with alcohol-related problems. Findings support previous literature on the effect of combat exposure and negative urgency on PTSD and subsequent alcohol-related problems. The current study also contributes to the limited research regarding the relationship between MST, PSTD, and alcohol use and related problems. Clinical interventions aimed at reducing emotional dysregulation and posttraumatic stress symptomology may subsequently improve alcohol-related outcomes. (c) 2015 APA, all rights reserved).

Huefner, Jonathan C; Smith, Gail L; Stevens, Amy L

2017-10-13

The potential for negative peer influence has been well established in research, and there is a growing interest in how positive peer influence also impacts youth. No research, however, has concurrently examined positive and negative peer influence in the context of residential care. Clinical records for 886 residential care youth were used in a Hierarchical Linear Model analysis to examine the impact of negative and positive peer influence on naturally occurring patterns of serious problem behavior over time. Negative peer influence, where the majority of youth in a home manifested above the average number of serious behavior problems, occurred 13.7% of the time. Positive peer influence, where the majority of youth manifested no serious problem behaviors for the month, occurred 47.7% of the time. Overall, youth problem behavior improved over time. There were significantly lower rates of serious problem behavior in target youth during positive peer influence months. Conversely, there were significantly higher rates of serious problem behaviors in target youth during negative peer influence months. Negative peer influence had a relatively greater impact on target peers' serious behavior problems than did positive peer influence. Caregiver experience significantly reduced the impact of negative peer influence, but did not significantly augment positive peer influence. Months where negative peer influence was combined with inexperienced caregivers produced the highest rates of serious problem behavior. Our results support the view that residential programs for troubled youth need to create circumstances that promote positive and control for negative peer influence.

Non-Negative Spherical Deconvolution (NNSD) for estimation of fiber Orientation Distribution Function in single-/multi-shell diffusion MRI.

PubMed

Cheng, Jian; Deriche, Rachid; Jiang, Tianzi; Shen, Dinggang; Yap, Pew-Thian

2014-11-01

Spherical Deconvolution (SD) is commonly used for estimating fiber Orientation Distribution Functions (fODFs) from diffusion-weighted signals. Existing SD methods can be classified into two categories: 1) Continuous Representation based SD (CR-SD), where typically Spherical Harmonic (SH) representation is used for convenient analytical solutions, and 2) Discrete Representation based SD (DR-SD), where the signal profile is represented by a discrete set of basis functions uniformly oriented on the unit sphere. A feasible fODF should be non-negative and should integrate to unity throughout the unit sphere S(2). However, to our knowledge, most existing SH-based SD methods enforce non-negativity only on discretized points and not the whole continuum of S(2). Maximum Entropy SD (MESD) and Cartesian Tensor Fiber Orientation Distributions (CT-FOD) are the only SD methods that ensure non-negativity throughout the unit sphere. They are however computational intensive and are susceptible to errors caused by numerical spherical integration. Existing SD methods are also known to overestimate the number of fiber directions, especially in regions with low anisotropy. DR-SD introduces additional error in peak detection owing to the angular discretization of the unit sphere. This paper proposes a SD framework, called Non-Negative SD (NNSD), to overcome all the limitations above. NNSD is significantly less susceptible to the false-positive peaks, uses SH representation for efficient analytical spherical deconvolution, and allows accurate peak detection throughout the whole unit sphere. We further show that NNSD and most existing SD methods can be extended to work on multi-shell data by introducing a three-dimensional fiber response function. We evaluated NNSD in comparison with Constrained SD (CSD), a quadratic programming variant of CSD, MESD, and an L1-norm regularized non-negative least-squares DR-SD. Experiments on synthetic and real single-/multi-shell data indicate that NNSD improves estimation performance in terms of mean difference of angles, peak detection consistency, and anisotropy contrast between isotropic and anisotropic regions.

How we think they see us? Valence and difficulty of retrieval as moderators of the effect of meta-stereotype activation on intergroup orientations.

PubMed

Vázquez, Alexandra; Yzerbyt, Vincent; Dovidio, John F; Gómez, Ángel

2017-12-01

Previous research indicates that meta-stereotypes are predominantly negative. However, the valence of the meta-stereotypes may not be the only factor accounting for the detrimental effects associated with their activation. In addition to valence, we propose that the subjective difficulty of retrieving the meta-stereotype might critically determine whether its activation deteriorates intergroup orientations. An experimental study showed that the effect of the meta-stereotype activation on the desire to interact with outgroup members was moderated by the interaction between the valence of the meta-stereotype and its difficulty of retrieval. In particular, the activation of a positive meta-stereotype deteriorated intergroup orientations when the difficulty of retrieval was high as compared with a condition in which the difficulty of retrieval was low. In sharp contrast, the activation of a negative meta-stereotype worsened intergroup orientations when the difficulty of retrieval was low as compared with a condition in which the difficulty of retrieval was high. © 2016 International Union of Psychological Science.

Phosphodiesterase Inhibition Increases CREB Phosphorylation and Restores Orientation Selectivity in a Model of Fetal Alcohol Spectrum Disorders

PubMed Central

Krahe, Thomas E.; Wang, Weili; Medina, Alexandre E.

2009-01-01

Background Fetal alcohol spectrum disorders (FASD) are the leading cause of mental retardation in the western world and children with FASD present altered somatosensory, auditory and visual processing. There is growing evidence that some of these sensory processing problems may be related to altered cortical maps caused by impaired developmental neuronal plasticity. Methodology/Principal Findings Here we show that the primary visual cortex of ferrets exposed to alcohol during the third trimester equivalent of human gestation have decreased CREB phosphorylation and poor orientation selectivity revealed by western blotting, optical imaging of intrinsic signals and single-unit extracellular recording techniques. Treating animals several days after the period of alcohol exposure with a phosphodiesterase type 1 inhibitor (Vinpocetine) increased CREB phosphorylation and restored orientation selectivity columns and neuronal orientation tuning. Conclusions/Significance These findings suggest that CREB function is important for the maturation of orientation selectivity and that plasticity enhancement by vinpocetine may play a role in the treatment of sensory problems in FASD.

Social problem-solving abilities and personality disorder characteristics among dual-diagnosed persons in substance abuse treatment.

PubMed

Herrick, S M; Elliott, T R

2001-01-01

We examined the relation of self-appraised social problem-solving abilities and personality-disorder characteristics to the adjustment and compliance of persons with dual diagnoses in substance-abuse treatment. It was hypothesized that elements of the problem-orientation component would remain predictive of depressive behavior and distress after considering personality-disorder characteristics among 117 persons receiving inpatient-substance-abuse treatment. Furthermore, self-appraised problem-solving abilities were expected to predict the occurrence of "dirty" drug and alcohol screens during treatment and compliance with the first scheduled community follow-up visit. Results supported predictions concerning the relation of problem-solving confidence to depressive behavior, distress, and substance-use screens; however, a paradoxical relation was observed between the problem-orientation variables and compliance with the first outpatient visit. The results are interpreted within the context of contemporary models of social problem solving and the implications for cognitive-behavioral assessment and intervention are considered.

Relationships between cooperation and goal orientation among male professional and semi-professional team athletes.

PubMed

Lameiras, João; Almeida, Pedro L; Garcia-Mas, Alexandre

2014-12-01

In team sports, athletes' goals may focus on the task (enhancing performance, developing better skills, etc.) or on ego (being better than the others, achieving superiority, etc.). This study investigated the relationships between athletes' goal orientation and their tendency to cooperate with teammates and coaches. 158 professional men (M age = 24.1 yr., SD = 4.6) who played on various sport teams participated in this study. Goal orientation was measured with the Portuguese version of the Task and Ego Orientation in Sport Questionnaire, and cooperation was measured with the Questionário de Cooperação Desportiva. Cooperation was positively correlated with task orientation, and negatively correlated with ego orientation. Overall, the findings support that in sports, directing the players' focus on task may promote prosocial behavior.

Using Balanced Time Perspective to Explain Well-Being and Planning in Retirement

PubMed Central

Mooney, Anna; Earl, Joanne K.; Mooney, Carl H.; Bateman, Hazel

2017-01-01

The notion of whether people focus on the past, present or future, and how it shapes their behavior is known as Time Perspective. Fundamental to the work of two of its earliest proponents, Zimbardo and Boyd (2008), was the concept of balanced time perspective and its relationship to wellness. A person with balanced time perspective can be expected to have a flexible temporal focus of mostly positive orientations (past-positive, present-hedonistic, and future) and much less negative orientations (past-negative and present-fatalistic). This study measured deviation from balanced time perspective (DBTP: Zhang et al., 2013) in a sample of 243 mature adults aged 45 to 91 years and explored relationships to Retirement Planning, Depression, Anxiety, Stress, Positive Mood, and Negative Mood. Results indicate that DBTP accounts for unexplained variance in the outcome measures even after controlling for demographic variables. DBTP was negatively related to Retirement Planning and Positive Mood and positively related to Depression, Anxiety, Stress, and Negative Mood. Theoretical and practical implications regarding balanced time perspective are discussed. PMID:29081757

The relevance of goal-orientation for motivation in high versus low proneness to negative symptoms.

Schlier, Björn; Engel, Maike; Fladung, Anne-Katharina; Fritzsche, Anja; Lincoln, Tania M

2017-06-01

The psychological mechanisms of why individuals with negative symptoms fail to initiate and perform goal-directed behavior are not well understood. Drawing on the reward-sensitivity and expectancy-value theories, we investigate whether negative symptom-like experiences (NSLE) are associated with generating less approach goals (aimed at reaching a positive outcome) and more avoidance goals (aimed at avoiding a negative outcome) and whether this type of goal-orientation explains motivational deficits (i.e., perceiving goals as less feasible and important and being less committed to them). Based on the continuum model of negative symptoms, we identified two parallelized extreme groups with high and low levels of NSLE (n = 37, respectively) in an ad-hoc online-sample of healthy individuals (N = 262) using the Community Assessment of Psychic Experiences. In an online study, these participants were instructed to generate approach and avoidance goals and to rate each goal in terms of feasibility, importance and goal-commitment. Participants with low levels of NSLE generated more approach than avoidance goals. Participants with high levels of NSLE showed no such difference due to increased numbers of avoidance goals. Furthermore, avoidance goal-orientation predicted reduced subjective feasibility and importance of goals and less goal-commitment. Results are based on a healthy sample rather than people with psychosis. No longitudinal or behavioral data for goal-striving was collected. People with NSLE generate more avoidance goals than controls. This is dysfunctional because it correlates with feeling less committed to reach one's goals. Optimizing goal-setting could be a promising starting-point for psychological interventions aimed at reducing negative symptoms. Copyright © 2017 Elsevier Ltd. All rights reserved.

Siblings are special: initial test of a new approach for preventing youth behavior problems.

Feinberg, Mark E; Solmeyer, Anna R; Hostetler, Michelle L; Sakuma, Kari-Lyn; Jones, Damon; McHale, Susan M

2013-08-01

A growing body of research documents the significance of siblings and sibling relationships for development, mental health, and behavioral risk across childhood and adolescence. Nonetheless, few well-designed efforts have been undertaken to promote positive and reduce negative youth outcomes by enhancing sibling relationships. Based on a theoretical model of sibling influences, we conducted a randomized trial of Siblings Are Special (SIBS), a group-format afterschool program for fifth graders with a younger sibling in second through fourth grades, which entailed 12 weekly afterschool sessions and three Family Nights. We tested program efficacy with a pre- and post-test design with 174 families randomly assigned to condition. In home visits at both time points, we collected data via parent questionnaires, child interviews, and observer-rated videotaped interactions and teachers rated children's behavior at school. The program enhanced positive sibling relationships, appropriate strategies for parenting siblings, and child self-control, social competence, and academic performance; program exposure was also associated with reduced maternal depression and child internalizing problems. Results were robust across the sample, not qualified by sibling gender, age, family demographics, or baseline risk. No effects were found for sibling conflict, collusion, or child externalizing problems; we will examine follow-up data to determine if short-term impacts lead to reduced negative behaviors over time. The breadth of the SIBS program's impact is consistent with research suggesting that siblings are an important influence on development and adjustment and supports our argument that a sibling focus should be incorporated into youth and family-oriented prevention programs.

2011-01-01

This study examined college student drinkers by sexual orientation (SO), alcohol use, and negative consequences in a national sample that self-identified gender and SO. Students completing the Spring 2005 National College Health Assessment (N = 54,111). A secondary analysis was conducted examining student responses by SO to items regarding negative consequences associated with alcohol. Bisexual students had the highest mean scores on an index of alcohol-related harm. Significant differences were found by SO among male high-risk drinkers for alcohol-related consequences of "fighting" and "injuring another," and females for "injuring another" and "unprotected sex." Bisexual students had significantly greater than expected cell counts for significant results, including a significant finding for bisexual low-risk female students for alcohol-related "regret." These findings suggest that more research is necessary to discern real differences in alcohol-related risk among college students by sexual orientation.

Discourse in freshman engineering teams: The relationship between verbal persuasions, self-efficacy, and achievement

NASA Astrophysics Data System (ADS)

Yasar, Senay

Collaborative teamwork is a common practice in both science and engineering schools and workplaces. This study, using a mixed-methods approach, was designed to identify which team discourse characteristics are correlated with changes in student self-efficacy and achievement. Bandura's self-efficacy theory constitutes the theoretical framework. Seven teams, consisting of first-year engineering students, took the pre- and post-surveys and were video- and audio-recorded during a semester-long Introduction to Engineering Design course. Three instruments were developed: a self-efficacy survey, a team interaction observation protocol, and a team interaction self-report survey. The reliability and validity of these instruments were established. An iterative process of code development and refinement led to the development of thirty-five discourse types, which were grouped under six discourse categories: task-oriented, response-oriented, learning-oriented, support-oriented, challenge-oriented, and disruptive. The results of the quantitative data analysis showed that achievement and gain in self-efficacy were significantly correlated ( r=.55, p<.01). There was also a positive correlation between support-orientated discourse and post self-efficacy scores ( r=.43, p<.05). Negative correlations were observed between disruptive discourse behaviors and post self-efficacy (r=-.48, p<.05). Neither being challenged by peers nor receiving negative feedback revealed significant correlations with student self-efficacy. In addition, no direct correlations between the team discourse characteristics and achievement were found. These findings suggest that collaborative teamwork can lead to achievement to the extent that it supports self-efficacy. They also suggest that interactions such as receiving positive or negative feedback have less impact on self-efficacy than does the overall constructive behavior of the group. The qualitative component of the study, which focused on three case studies, presents how supportive and disruptive interactions occurred during team discourse. Discussion includes recommendations for educators on how to help teams build supportive environments as well as what to look for when forming teams and evaluating student team interactions.

A cylindrical shell with an arbitrarily oriented crack

Yahsi, O. S.; Erdogan, F.

1982-01-01

The general problem of a shallow shell with constant curvatures is considered. It is assumed that the shell contains an arbitrarily oriented through crack and the material is specially orthotropic. The nonsymmetric problem is solved for arbitrary self equilibrating crack surface tractions, which, added to an appropriate solution for an uncracked shell, would give the result for a cracked shell under most general loading conditions. The problem is reduced to a system of five singular integral equations in a set of unknown functions representing relative displacements and rotations on the crack surfaces. The stress state around the crack tip is asymptotically analyzed and it is shown that the results are identical to those obtained from the two dimensional in plane and antiplane elasticity solutions. The numerical results are given for a cylindrical shell containing an arbitrarily oriented through crack. Some sample results showing the effect of the Poisson's ratio and the material orthotropy are also presented.

Interaction between a circular inclusion and an arbitrarily oriented crack

1975-01-01

The plane interaction problem for a circular elastic inclusion embedded in an elastic matrix which contains an arbitrarily oriented crack is considered. Using the existing solutions for the edge dislocations as Green's functions, first the general problem of a through crack in the form of an arbitrary smooth arc located in the matrix in the vicinity of the inclusion is formulated. The integral equations for the line crack are then obtained as a system of singular integral equations with simple Cauchy kernels. The singular behavior of the stresses around the crack tips is examined and the expressions for the stress-intensity factors representing the strength of the stress singularities are obtained in terms of the asymptotic values of the density functions of the integral equations. The problem is solved for various typical crack orientations and the corresponding stress-intensity factors are given.

Calculation of susceptibility through multiple orientation sampling (COSMOS): a method for conditioning the inverse problem from measured magnetic field map to susceptibility source image in MRI.

Magnetic susceptibility differs among tissues based on their contents of iron, calcium, contrast agent, and other molecular compositions. Susceptibility modifies the magnetic field detected in the MR signal phase. The determination of an arbitrary susceptibility distribution from the induced field shifts is a challenging, ill-posed inverse problem. A method called "calculation of susceptibility through multiple orientation sampling" (COSMOS) is proposed to stabilize this inverse problem. The field created by the susceptibility distribution is sampled at multiple orientations with respect to the polarization field, B(0), and the susceptibility map is reconstructed by weighted linear least squares to account for field noise and the signal void region. Numerical simulations and phantom and in vitro imaging validations demonstrated that COSMOS is a stable and precise approach to quantify a susceptibility distribution using MRI.

Predicting academic self-handicapping in different age groups: the role of personal achievement goals and social goals.

PubMed

Leondari, Angeliki; Gonida, Eleftheria

2007-09-01

Academic self-handicapping refers to the use of impediments to successful performance on academic tasks. Previous studies have shown that it is related to personal achievement goals. A performance goal orientation is a positive predictor of self-handicapping, whereas a task goal orientation is unrelated to self-handicapping. The aim of this study was to examine the relationship between academic self-handicapping, goal orientations (task, performance-approach, performance-avoidance), social goals, future consequences and achievement in mathematics. An additional aim was to investigate grade-level and gender differences in relation to academic self-handicapping. Participants were 702 upper elementary, junior and senior high school students with approximately equal numbers of girls and boys. There were no grade-level or gender differences as regards the use of self-handicapping. The correlations among the variables revealed that, when the whole sample was considered, self-handicapping was positively related to performance goal orientations and pleasing significant others and negatively to achievement in mathematics. The results of hierarchical regression analysis showed that, in upper elementary and junior high schools, the association between achievement in mathematics and self-handicapping was mediated by performance-avoidance goals. In senior high school, only task goal orientation was a negative predictor of self-handicapping.

Gender roles, eating pathology, and body dissatisfaction in men: a meta-analysis.

2011-01-01

The current study reviewed relationships between gender roles and (a) eating pathology, (b) body dissatisfaction, and (c) muscle dissatisfaction among men via meta-analysis. Moderators of sexual orientation and type of gender role measure were also investigated. Results revealed the relationship between femininity and eating and body-related variables did not significantly differ from zero. Sexual orientation moderated the relationship between femininity and muscle dissatisfaction (i.e., femininity was negatively related to muscle dissatisfaction for heterosexual but not gay men). Masculinity was negatively associated with eating pathology and body dissatisfaction. Type of masculinity measure moderated the relationship between masculinity and body dissatisfaction (i.e., trait-based measures produced a negative association, multidimensional measures yielded nonsignificant relationships). Type of masculinity measure produced a cross-over interaction when examining muscle dissatisfaction (i.e., trait-based instruments yielded a negative association and multidimensional instruments revealed a positive relationship). Findings highlight the salience of masculinity in men's eating and body concerns. Copyright © 2010 Elsevier Ltd. All rights reserved.

Negative emotion enhances mnemonic precision and subjective feelings of remembering in visual long-term memory.

PubMed

Xie, Weizhen; Zhang, Weiwei

2017-09-01

Negative emotion sometimes enhances memory (higher accuracy and/or vividness, e.g., flashbulb memories). The present study investigates whether it is the qualitative (precision) or quantitative (the probability of successful retrieval) aspect of memory that drives these effects. In a visual long-term memory task, observers memorized colors (Experiment 1a) or orientations (Experiment 1b) of sequentially presented everyday objects under negative, neutral, or positive emotions induced with International Affective Picture System images. In a subsequent test phase, observers reconstructed objects' colors or orientations using the method of adjustment. We found that mnemonic precision was enhanced under the negative condition relative to the neutral and positive conditions. In contrast, the probability of successful retrieval was comparable across the emotion conditions. Furthermore, the boost in memory precision was associated with elevated subjective feelings of remembering (vividness and confidence) and metacognitive sensitivity in Experiment 2. Altogether, these findings suggest a novel precision-based account for emotional memories. Copyright © 2017 Elsevier B.V. All rights reserved.

Using Emotion as Information in Future-Oriented Cognition: Individual Differences in the Context of State Negative Affect

Marroquín, Brett; Boyle, Chloe C.; Nolen-Hoeksema, Susan; Stanton, Annette L.

2016-01-01

Predictions about the future are susceptible to mood-congruent influences of emotional state. However, recent work suggests individuals also differ in the degree to which they incorporate emotion into cognition. This study examined the role of such individual differences in the context of state negative emotion. We examined whether trait tendencies to use negative or positive emotion as information affect individuals' predictions of what will happen in the future (likelihood estimation) and how events will feel (affective forecasting), and whether trait influences depend on emotional state. Participants (N=119) reported on tendencies to use emotion as information (“following feelings”), underwent an emotion induction (negative versus neutral), and made likelihood estimates and affective forecasts for future events. Views of the future were predicted by both emotional state and individual differences in following feelings. Whereas following negative feelings affected most future-oriented cognition across emotional states, following positive feelings specifically buffered individuals' views of the future in the negative emotion condition, and specifically for positive future events, a category of future-event prediction especially important in psychological health. Individual differences may confer predisposition toward optimistic or pessimistic expectations of the future in the context of acute negative emotion, with implications for adaptive and maladaptive functioning.

Cheng, Hongju; Su, Zhihuang; Lloret, Jaime; Chen, Guolong

2014-01-01

Future wireless sensor networks are expected to provide various sensing services and energy efficiency is one of the most important criterions. The node scheduling strategy aims to increase network lifetime by selecting a set of sensor nodes to provide the required sensing services in a periodic manner. In this paper, we are concerned with the service-oriented node scheduling problem to provide multiple sensing services while maximizing the network lifetime. We firstly introduce how to model the data correlation for different services by using Markov Random Field (MRF) model. Secondly, we formulate the service-oriented node scheduling issue into three different problems, namely, the multi-service data denoising problem which aims at minimizing the noise level of sensed data, the representative node selection problem concerning with selecting a number of active nodes while determining the services they provide, and the multi-service node scheduling problem which aims at maximizing the network lifetime. Thirdly, we propose a Multi-service Data Denoising (MDD) algorithm, a novel multi-service Representative node Selection and service Determination (RSD) algorithm, and a novel MRF-based Multi-service Node Scheduling (MMNS) scheme to solve the above three problems respectively. Finally, extensive experiments demonstrate that the proposed scheme efficiently extends the network lifetime. PMID:25384005

The social meaning of disability: a reflection on categorisation, stigma and identity.

PubMed

Grue, Jan

2016-07-01

As disability becomes an ever more salient concept in international political and legal discourse, its social meaning must be better understood. Traditionally defined in medical terms and as an individual problem, it has for the last several decades increasingly become a socio-politically defined phenomenon. Disability pride has emerged as a social movement patterned after ethnic minority and sexual orientation movements. The one billion people who count as disabled nevertheless have illnesses and impairments that are largely understood as medical problems. Medicine continues to exert great influence on the social meaning of disability in general and the social valuation of various illnesses and impairments in particular. Whereas specific conditions may be socially valued, the overall category and label of disability connotes marginality and stigma. Under these conditions, disability policy, which ought to be a universal concern, risks being construed as a marginal and special-interest issue rather than a broadly relevant topic; this has potentially negative consequences for the majority of disabled people. © 2016 Foundation for the Sociology of Health & Illness.

Age-related perspectives and emotion processing.

PubMed

Lynchard, Nicholas A; Radvansky, Gabriel A

2012-12-01

Emotion is processed differently in younger and older adults. Older adults show a positivity effect, whereas younger adults show a negativity effect. Socioemotional selectivity theory suggests that these effects can be elicited in any age group when age-related perspectives are manipulated. To examine this, younger and older adults were oriented to actual and age-contrasting possible selves. Emotion activations were assessed using lexical decision. In line with socioemotional selectivity theory, shifts in emotion orientation varied according to perspective, with both younger and older adults showing a negativity effect when a younger adult perspective was taken and a positivity effect when an older adult perspective was taken. 2013 APA, all rights reserved

Consideration of learning orientations as an application of achievement goals in evaluating life science majors in introductory physics

NASA Astrophysics Data System (ADS)

Mason, Andrew J.; Bertram, Charles A.

2018-06-01

When considering performing an Introductory Physics for Life Sciences course transformation for one's own institution, life science majors' achievement goals are a necessary consideration to ensure the pedagogical transformation will be effective. However, achievement goals are rarely an explicit consideration in physics education research topics such as metacognition. We investigate a sample population of 218 students in a first-semester introductory algebra-based physics course, drawn from 14 laboratory sections within six semesters of course sections, to determine the influence of achievement goals on life science majors' attitudes towards physics. Learning orientations that, respectively, pertain to mastery goals and performance goals, in addition to a learning orientation that does not report a performance goal, were recorded from students in the specific context of learning a problem-solving framework during an in-class exercise. Students' learning orientations, defined within the context of students' self-reported statements in the specific context of a problem-solving-related research-based course implementation, are compared to pre-post results on physics problem-solving items in a well-established attitudinal survey instrument, in order to establish the categories' validity. In addition, mastery-related and performance-related orientations appear to extend to overall pre-post attitudinal shifts, but not to force and motion concepts or to overall course grade, within the scope of an introductory physics course. There also appears to be differentiation regarding overall course performance within health science majors, but not within biology majors, in terms of learning orientations; however, health science majors generally appear to fare less well on all measurements in the study than do biology majors, regardless of learning orientations.

Is the gap more than gender? A longitudinal analysis of gender, gender role orientation, and earnings.

PubMed

Judge, Timothy A; Livingston, Beth A

2008-09-01

This study investigated the relationships among gender, gender role orientation (i.e., attitudes toward the gendered separation of roles at work and at home), and earnings. A multilevel model was conceptualized in which gender role orientation and earnings were within-individual variables that fluctuate over time (although predictors of between-individual differences in gender role orientation were also considered). Results indicated that whereas traditional gender role orientation was positively related to earnings, gender significantly predicted the slope of this relationship: Traditional gender role orientation was strongly positively associated with earnings for men; it was slightly negatively associated with earnings for women. Occupational segregation partly explained these gender differences. Overall, the results suggest that although gender role attitudes are becoming less traditional for men and for women, traditional gender role orientation continues to exacerbate the gender wage gap.

Comparing catch orientation among Minnesota walleye, northern pike, and bass anglers

Schroeder, Susan A.; Fulton, David C.

2013-01-01

We compared the catch orientations of Minnesota walleye (Sander vitreus), northern pike (Esox lucius), largemouth bass (Micropterus salmoides), and smallmouth bass (Micropterus dolomieu) anglers. Results were derived from 2009, 2010, and 2012 surveys of anglers targeting these different species. Consistent with previous research, we identified four dimensions of anglers’ catch orientation: (a) catching something, (b) catching big fish, (c) catching many fish, and (d) keeping fish. Walleye anglers were the most motivated to keep fish, while northern pike anglers were more oriented toward catching big fish. Largemouth bass anglers, and to a lesser extent smallmouth bass anglers, were also oriented toward catching big fish. Bass anglers reported the lowest interest in keeping fish. An orientation to keep fish was negatively related to more restrictive management actions, regardless of species. A stronger orientation to catch big fish was associated with support for increased harvest restrictions only for northern pike and smallmouth bass.

Studies indicate that a dysfunctional attributional style, problem-solving deficits and hopelessness place youths at risk of developing suicidal thoughts and engaging in suicidal behaviour. However, in the realm of suicidality in adolescent, no study has examined the linkages between these three cognitive variables and suicidal ideation in non-clinical samples while taking into account the moderating role of gender on the relationships and controlling for depression. In this community study of 712 adolescents 14-18 years of age, through a multivariate approach, the interaction between the cognitive variables, depression and gender was examined with depression controlled in the analyses. Problem-solving deficits and hopelessness proved predictive of such ideation whether or not depressive symptoms were controlled in the analyses. Negative problem orientation/avoidant style was more predictive of ideation in boys than in girls. On the other hand, hopelessness was more predictive for girls than boys. Results were based on a convenience community sample of adolescents and a cross-sectional survey. Results suggest that a unique explanatory model of the suicide process in adolescence that fails to take account of gender would be ill informed. Suicide prevention strategies should be differentiated according to gender with a stronger emphasis in hopelessness in female adolescents, and problem-solving deficits in male adolescents.

Souba, Wiley W; Day, David V

2006-01-01

To gain a deeper understanding of the guiding core values that deans of academic medical centers (AMCs) considered most essential for their leadership and the major leadership challenges that confront them. In 2003-04, semistructured interviews of 18 deans at U.S. colleges of medicine or AMCs were organized around four dimensions: background, leadership challenges, organizational effectiveness, and systems enablers/restrainers for leadership. A values Q-sort was used to determine how widely core values were shared among deans and how the complex challenges they faced did or did not align with these values. Fourteen of the 18 (78%) deans identified financial difficulties as their most pressing leadership challenge, followed by weak institutional alignment (61%), staffing problems (33%), and poor morale (28%). Open, candid communication was reported as the most effective means of addressing these complex problems. Enacting espoused shared values and having a positive attitude were identified as the most important enablers of systemic leadership, whereas micromanagement and difficult people were the major restraints. Q-sort results on 38 positive leadership values indicated that participants considered integrity most essential. Integrity was positively correlated with humanistic values and negatively correlated with results. Vision, another highly espoused value, correlated strongly with performance-oriented values but correlated negatively with humanistic values. A dynamic tension exists in AMCs between humanistic values and performance-based core values. The ability to manage that tension (i.e., when to prioritize one set of values over the other) is inherent in a dean's work.

Gender nonconformity, sexual orientation, and psychological well-being.

PubMed

Rieger, Gerulf; Savin-Williams, Ritch C

2012-06-01

Both a same-sex sexual orientation and gender nonconformity have been linked with poorer well-being; however, sexual orientation and gender nonconformity are also correlated. It is, therefore, critical to investigate their independent contributions to well-being. Based on survey responses of 230 female and 245 male high school seniors, the present study is one of the first to provide empirical data on this topic. Both childhood and adolescent gender nonconformity were negatively related to well-being. In the same analyses, neither sexual orientation nor biological sex was a significant predictor of well-being. These results suggest that gender-atypical traits may be more relevant for psychological health than a same-sex sexual orientation. Both environmental and biological influences may account for these findings.

The aim of this study was to examine the relationship between the perceived motivational climate, achievement goals, perfectionism and indices of peer relationships in a sample of young male and female Norwegian soccer players. The sample consisted of 1719 experienced soccer players (1231 males, 488 females) aged 12-19 years (mean = 14.9 years) participating in the Norway Cup international youth soccer competition. The players responded to a questionnaire measuring perceived peer acceptance and quality of friendship in soccer, perceived motivational climate, achievement goals and perfectionism in soccer. Canonical correlation analyses revealed that young female players who perceived the motivational climate as predominantly mastery oriented, and who were moderately task oriented and scored negatively on maladaptive perfectionism, reported better relations with their peers in soccer. Constructive peer relations were evident in that they scored positively on companionship with their best friend in soccer; they perceived this friend as being loyal and allowing of free discussion, and they reported being socially accepted by their peers in soccer. Mirroring these findings, young male players who perceived the motivational climate as predominantly performance oriented, who had a moderately negative score on task orientation but a quite strong positive score on maladaptive perfectionism, reported negative relationships with peers in terms of these aspects. They also reported being in conflict with their best soccer friend. The findings suggest that the qualities of motivation have a systematic relationship with peer acceptance and the quality of friendship in male and female youth soccer.

Homosexual orientation-from nature, not abuse: A critique of Roberts, Glymour, and Koenen (2013).

PubMed

Rind, Bruce

2013-11-01

Roberts, Glymour, and Koenen (2013), using instrumental variable models, argued that child abuse causes homosexual orientation, defined in part as any same-sex attractions. Their instruments were various negative family environment factors. In their analyses, they found that child sexual abuse (CSA) was more strongly related to homosexual orientation than non-sexual maltreatment was, especially among males. The present commentary therefore focused on male CSA. It is argued that Roberts et al.'s "abuse model" is incorrect and an alternative is presented. Male homosexual behavior is common in primates and has been common in many human societies, such that an evolved human male homosexual potential, with individual variation, can be assumed. Cultural variation has been strongly influenced by cultural norms. In our society, homosexual expression is rare because it is counternormative. The "counternormativity model" offered here holds that negative family environment weakens normative controls and increases counternormative thinking and behavior, which, in combination with sufficient homosexual potential and relevant, reinforcing experiences, can produce a homosexual orientation. This is a benign or positive model (innate potential plus release and reinforcement), in contrast to Roberts et al.'s negative model (abuse plus emotional compensation or cognitive distortion). The abuse model is criticized for being based on the sexual victimological paradigm, which developed to describe the female experience in rape and incest. This poorly fits the gay male experience, as demonstrated in a brief non-clinical literature review. Validly understanding male homosexuality, it is argued, requires the broad perspective, as employed here.

Ethical issues in action-oriented research in Indonesia.

PubMed

Rachmawaty, Rini

2017-09-01

Action-oriented research is one of the most frequent research types implemented to transform community health in Indonesia. Three researchers and 11 graduate students from a developed country in East Asia conducted a fieldwork program in a remote area in South Sulawesi Province. Although the project was completed, whether or not the international standards for human subject research were applied into that study remains unclear. This study aimed to examine ethical issues raised from that case, analyze constraints to the problems, and recommend alternatives to protect vulnerable populations from being exploited by local/international researchers. A problem-solving approach was used in this study. It began with problem identification, evaluation of the action-oriented research goal, investigation of the constraints to the problem, and recommendation of some relevant alternatives to address the central issue. Ethical Consideration: The approval for conducting the action-oriented research that being investigated in this work was only obtained from the Head of local district. Some ethical issues were found in this case. No special protection for this population, no informed consent was obtained from the participants, exposure to social and economic risks, no future benefits for the subjects, and conflict of interests. Lack of control from the local research ethics committee and lack of competence of local researchers on human subject research were considered as the constraints to the problems. Creating an independent research ethics committee, providing research ethics training to the local researchers, obtaining written/video consents from underserved populations, and meeting local health needs were recommended alternatives to solve these problems. Indonesian government bodies should reform their international collaborative system on research involving human subjects. Exploitation may not occur if all participants as well as all local and national governing bodies understand the research ethics on human subjects and apply it into their practice.

Effects of cadmium and zinc toxicity on orientation behaviour of Echinoparyphium recurvatum (Digenea: Echinostomatidae) cercariae.

Morley, N J; Crane, M; Lewis, J W

2003-08-15

The effects of cadmium and zinc toxicity on orientation behaviour (photo- and geo-taxis) of Echinoparyphium recurvatum cercariae was investigated at concentrations ranging from 10 to 1000 microg l(-1). Exposure to the toxicants at all metal concentrations caused a change in orientation to negative phototaxis and positive geotaxis during the submaximal dispersal phase (0.5 h cercarial age). Autometallography staining of cercariae exposed to 1000 microg l(-1) cadmium or zinc showed selective binding of heavy metals to tegumental surface sites associated with sensory receptors. The significance to parasite transmission of changes in cercarial orientation behaviour in metal polluted environments is discussed.

The relation between gender role orientation and fear and anxiety in nonclinic-referred children.

Muris, Peter; Meesters, Cor; Knoops, Miranda

2005-06-01

This study examined the relation between gender role orientation and fear and anxiety in a sample of nonclinic-referred children (N = 209) ages 10 to 13 years. Children and their parents completed questionnaires assessing children's gender role orientation, toy and activity preferences, and fear and anxiety. Results generally indicated that femininity and a preference for girls' toys and activities were positively associated with fear and anxiety, whereas masculinity and a preference for boys' toys and activities were negatively related to these emotions. Furthermore, gender role orientation accounted for more of the variance in fear and anxiety scores than the child's sex.

What predicts recovery orientation in county departments of mental health? A pilot study.

Brown, Timothy T; Mahoney, Christine B; Adams, Neal; Felton, Mistique; Pareja, Candy

2010-09-01

In this pilot study we examined the determinants of recovery orientation among employees and influential stakeholders in a sample of 12 county departments of mental health in California. A two-level hierarchical linear model with random intercepts was estimated. Analyses show that recovery orientation has a U-shaped relationship with the age of staff/influential stakeholders and is negatively related to the difference between the desired level of adhocracy and the current level of adhocracy. Recovery orientation is positively related to the education level of staff/influential stakeholders, satisfying transformational leadership outcomes, and larger mental health budgets per capita. Policy implications are discussed.

A life history approach to delineating how harsh environments and hawk temperament traits differentially shape children's problem-solving skills.

Suor, Jennifer H; Sturge-Apple, Melissa L; Davies, Patrick T; Cicchetti, Dante

2017-08-01

Harsh environments are known to predict deficits in children's cognitive abilities. Life history theory approaches challenge this interpretation, proposing stressed children's cognition becomes specialized to solve problems in fitness-enhancing ways. The goal of this study was to examine associations between early environmental harshness and children's problem-solving outcomes across tasks varying in ecological relevance. In addition, we utilize an evolutionary model of temperament toward further specifying whether hawk temperament traits moderate these associations. Two hundred and one mother-child dyads participated in a prospective multimethod study when children were 2 and 4 years old. At age 2, environmental harshness was assessed via maternal report of earned income and observations of maternal disengagement during a parent-child interaction task. Children's hawk temperament traits were assessed from a series of unfamiliar episodes. At age 4, children's reward-oriented and visual problem-solving were measured. Path analyses revealed early environmental harshness and children's hawk temperament traits predicted worse visual problem-solving. Results showed a significant two-way interaction between children's hawk temperament traits and environmental harshness on reward-oriented problem-solving. Simple slope analyses revealed the effect of environmental harshness on reward-oriented problem-solving was specific to children with higher levels of hawk traits. Results suggest early experiences of environmental harshness and child hawk temperament traits shape children's trajectories of problem-solving in an environment-fitting manner. © 2017 Association for Child and Adolescent Mental Health.

MEDRIS (The Medical Record Interface System) is an object oriented HyperCard interface designed to help physicians enter patient information as comfortably and naturally as possible. It can function as a stand alone system producing its own reports or serve as an interface to a medical expert system (e.g., MEDAS). MEDRIS plays an important role in the clinical education of medical students at the Chicago Medical School. MEDRIS portrays an intuitive, graphically oriented system that will provide a learning environment for the problem oriented medical record (POMR) that forms the basis of the structure of the history and physical exam. The enthusiasm shown by the medical students for this project has garnered support for including MEDRIS in the curriculum of the Introduction to Clinical Medicine course this semester. MEDRIS, developed using HyperCard, can be used as a tool not only for teaching POMR and physical diagnosis, but also computer literacy.

Cultural Orientation as a Moderator of the Relationship Between Chinese American Adolescents’ Discrimination Experiences and Delinquent Behaviors

Deng, Shiying; Vaughan, Phillip W.; Li, Jing

2009-01-01

The purpose of this study was to examine the relationships among Chinese American adolescents’ discrimination experiences, cultural orientations, and delinquent behaviors. Data were collected from three hundred and eleven Chinese American adolescents (58% girls) and their parents when the adolescents were 7th or 8th graders and again 4 years later. The data analyses demonstrated that adolescents’ perceptions of discrimination and victimization experiences were significantly related to their delinquent behaviors conditionally based upon their cultural orientation. Specifically, adolescents’ high Chinese cultural orientation amplified the negative impact of discriminatory experiences on delinquent behaviors whereas high Western cultural orientation protected them against that impact. The significance of both ethnic and mainstream cultural orientations for understanding ethnic minority adolescents’ adjustment and improving their adjustment outcomes is discussed. PMID:19834795

First quantification of relationship between dune orientation and sediment availability, Olympia Undae, Mars

Fernandez-Cascales, Laura; Lucas, Antoine; Rodriguez, Sébastien; Gao, Xin; Spiga, Aymeric; Narteau, Clément

2018-05-01

Dunes provide unique information about wind regimes on planetary bodies where there is no direct meteorological data. At the eastern margin of Olympia Undae on Mars, dune orientation is measured from satellite imagery and sediment cover is estimated using the high contrast between the dune material and substrate. The analysis of these data provide the first quantification of relationship between sediment availability and dune orientation. Abrupt and smooth dune reorientations are associated with inward and outward dynamics of dunes approaching and ejecting from major sedimentary bodies, respectively. These reorientation patterns along sediment transport pathways are interpreted using a new generation dune model based on the coexistence of two dune growth mechanisms. This model also permits solving of the inverse problem of predicting the wind regime from dune orientation. For bidirectional wind regimes, solutions of this inverse problem show substantial differences in the distributions of sediment flux orientation, which can be attributed to atmospheric flow variations induced by changes in albedo at the boundaries of major dune fields. Then, we conclude that relationships between sediment cover and dune orientation can be used to constrain wind regime and dune field development on Mars and other planetary surfaces.

A Method of Face Detection with Bayesian Probability

NASA Astrophysics Data System (ADS)

Sarker, Goutam

2010-10-01

The objective of face detection is to identify all images which contain a face, irrespective of its orientation, illumination conditions etc. This is a hard problem, because the faces are highly variable in size, shape lighting conditions etc. Many methods have been designed and developed to detect faces in a single image. The present paper is based on one `Appearance Based Method' which relies on learning the facial and non facial features from image examples. This in its turn is based on statistical analysis of examples and counter examples of facial images and employs Bayesian Conditional Classification Rule to detect the probability of belongingness of a face (or non-face) within an image frame. The detection rate of the present system is very high and thereby the number of false positive and false negative detection is substantially low.

It is well documented that friends' externalizing problems and negative parent-child interactions predict externalizing problems in adolescence, but relatively little is known about the role of siblings. This four-wave, multi-informant study investigated linkages of siblings' externalizing problems and sibling-adolescent negative interactions on adolescents' externalizing problems, while examining and controlling for similar linkages with friends and parents. Questionnaire data on externalizing problems and negative interactions were annually collected from 497 Dutch adolescents (M = 13.03 years, SD = 0.52, at baseline), as well as their siblings, mothers, fathers, and friends. Cross-lagged panel analyses revealed modest unique longitudinal paths from sibling externalizing problems to adolescent externalizing problems, for male and female adolescents, and for same-sex and mixed-sex sibling dyads, but only from older to younger siblings. Moreover, these paths were above and beyond significant paths from mother-adolescent negative interaction and friend externalizing problems to adolescent externalizing problems, 1 year later. No cross-lagged paths existed between sibling-adolescent negative interaction and adolescent externalizing problems. Taken together, it appears that especially older sibling externalizing problems may be a unique social risk factor for adolescent externalizing problems, equal in strength to significant parents' and friends' risk factors. © 2013 The Authors.

The objective of this study is to investigate to what extent psychiatric history affects preabortion decision difficulty, experienced burden, and postabortion emotions and coping. Women with and without a history of mental disorders might respond differently to unwanted pregnancy and subsequent abortion. Women who had an abortion (n=325) were classified as either with or without a history of mental disorders, using the Composite International Diagnostic Interview version 3.0. The two groups were compared on preabortion doubt, postabortion decision uncertainty, experienced pressure, experienced burden of unwanted pregnancy and abortion, and postabortion emotions, self-efficacy and coping. The study was conducted in the Netherlands. Data were collected using structured face-to-face interviews and analyzed with regression analyses. Compared to women without prior mental disorders, women with a psychiatric history were more likely to report higher levels of doubt [odds ratio (OR)=2.30; confidence interval (CI)=1.29-4.09], more burden of the pregnancy (OR=2.23; CI=1.34-3.70) and the abortion (OR=1.93; CI=1.12-3.34) and more negative postabortion emotions (β=.16; CI=.05-.28). They also scored lower on abortion-specific self-efficacy (β=-.11; CI=-.22 to .00) and higher on emotion-oriented (β=.22; .11-.33) and avoidance-oriented coping (β=.12; CI=.01-.24). The two groups did not differ significantly in terms of experienced pressure, decision uncertainty and positive postabortion emotions. Psychiatric history strongly affects women's pre- and postabortion experiences. Women with a history of mental disorders experience a more stressful pre- and postabortion period in terms of preabortion doubt, burden of pregnancy and abortion, and postabortion emotions, self-efficacy and coping. Negative abortion experiences may, at least partially, stem from prior or underlying mental health problems. Copyright © 2015 Elsevier Inc. All rights reserved.

2018-01-01

Problems in emotion processing potentially contribute to the development and maintenance of chronic pain. Theories focusing on attentional processing have suggested that dysfunctional attention deployment toward emotional information, i.e., attentional biases for negative emotions, might entail one potential developmental and/or maintenance factor of chronic pain. We assessed self-reported alexithymia, attentional orienting to and maintenance on emotional stimuli using eye tracking in 17 patients with chronic pain disorder (CP) and two age- and sex-matched control groups, 17 healthy individuals (HC) and 17 individuals who were matched to CP according to depressive symptoms (DC). In a choice viewing paradigm, a dot indicated the position of the emotional picture in the next trial to allow for strategic attention deployment. Picture pairs consisted of a happy or sad facial expression and a neutral facial expression of the same individual. Participants were asked to explore picture pairs freely. CP and DC groups reported higher alexithymia than the HC group. HC showed a previously reported emotionality bias by preferentially orienting to the emotional face and preferentially maintaining on the happy face. CP and DC participants showed no facilitated early attention to sad facial expressions, and DC participants showed no facilitated early attention to happy facial expressions, while CP and DC participants did. We found no group differences in attentional maintenance. Our findings are in line with the clinical large overlap between pain and depression. The blunted initial reaction to sadness could be interpreted as a failure of the attentional system to attend to evolutionary salient emotional stimuli or as an attempt to suppress negative emotions. These difficulties in emotion processing might contribute to etiology or maintenance of chronic pain and depression.

Sexual Orientation Disclosure in Primary Care Settings by Gay, Bisexual, and Other Men Who Have Sex with Men in a Canadian City.

Sexual orientation affects individuals' health histories and is fundamental to providers' understanding of patients as a whole. Gay, bisexual, and other men who have sex with men (GB-MSM) are vulnerable to certain health conditions, including HIV. The aim of this exploratory analysis was to examine factors associated with sexual orientation disclosure and communication with providers about GB-MSM health issues and to discuss implications. We conducted a cross-sectional internet survey of GB-MSM (n = 202) in London-Middlesex, Ontario, Canada; analyses were limited to those with a regular primary care provider (n = 173). Blockwise regression models explored demographic, psychosocial, and healthcare-related factors associated with sexual orientation disclosure and physician-patient communication about GB-MSM-related health. Just over seventy-one percent (71.1%) of participants reported that their primary care provider (PCP) knew their sexual orientation, and 44.5% had talked to them about GB-MSM health. Overt negative comments or being refused care based on sexual orientation occurred infrequently, although 26.6% reported their provider had assumed they were heterosexual. Being married to or living common-law with another man, more frequent experiences of homosexual prejudice, and higher quality assessment of provider's communication skills were associated with the PCP knowing respondents' sexual orientation. Greater internalized homonegativity was associated with not talking to a PCP about GB-MSM-related health issues. More frequent experiences of homosexual prejudice, higher assessment of provider communication, and having prior negative experiences with a PCP were significantly associated with talking to a PCP about GB-MSM health. The majority of our sample disclosed their sexual orientation; however, not all patients voluntarily disclose. Medical training and education in Canada, where specific rights protections exist for sexual orientation minority populations, should emphasize awareness of essential patient health information. Training should include information about GB-MSM health and building a foundation on how to speak with GB-MSM patients nonjudgmentally.

2014-02-01

Problem-oriented learning is an effective method of learning that increases students' learning motivation, improves the relationship amongst students and results in open-minded discussions. In this study, a new problem-oriented pharmacobiochemistry course related to 'oxidative metabolism of drugs by cytochrome P450 (CYP450) systems' was designed. Students were divided into seven groups. Three keywords related to drug interaction through CYP450 were provided to each group in order for them to conduct research on the information given. After 1 month, the groups attended a session under the supervision of a tutor to solve a simulated problem case that was designed using the keywords. At the end of the integrated course, a multiple-choice examination was given. The success rate of 76 students who attended the course was found to be significantly higher than the success rate of the students who received the lecture-based course only (P < 0.0001). A questionnaire containing 20 items (Cronbach's alpha: 0.92) was administered to the students to learn about their perception regarding this educational model. The questionnaire was evaluated using the Likert scale. Student feedback was very positive, with fourteen answers rated as 'agree' and the remaining six rated as 'strongly agree'. Students thought that the problem-oriented model was very enjoyable and useful in regard to dental education. Based on these results, we conclude that this course model may help achieve an integrated curriculum for dental school programmes. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Electron Spin Optical Orientation in Charged Quantum Dots

NASA Astrophysics Data System (ADS)

Shabaev, A.; Gershoni, D.; Korenev, V. L.

2005-03-01

We present a theory of nonresonant optical orientation of electron spins localized in quantum dots. This theory explains the negative circularly polarized photoluminescence of singlet trions localized in quantum dots previously observed in experiments where trion polarization changed to negative with time and where the degree of the negative polarization increased with intensity of pumping light. We have shown that this effect can be explained by the accumulation of dark excitons that occurs due to the spin blocking of the singlet trion formation - the major mechanism of dark exciton recombination. The accumulation of dark excitons results from a lack of electrons with a spin matching the exciton polarization. The electron spin lifetime is shortened by a transverse magnetic field or a temperature increase. This takes the block off the dark exciton recombination and restores the positive degree of trion polarization. The presented theory gives good agreement with experimental data.

To Refer or Not to Refer: Exploring Family Therapists' Beliefs and Practices Related to the Referral of Lesbian, Gay, and Bisexual Clients.

This study explored how negative beliefs toward lesbian, gay, and bisexual (LGB) individuals and LGB clinical competence influenced family therapists' beliefs and practices regarding referring based on the sexual orientation of the client. The sample consisted of 741 experienced clinicians. The results of this study indicated that the majority of the participants believe it is ethical to refer LGB clients; however, most had never made such a referral. Furthermore, participants who had referred based solely on the client's sexual orientation reported higher levels of negative beliefs toward LGB individuals and lower levels of LGB clinical competence. Finally, negative beliefs toward LGB persons not only predicted the practice of referring, but also the belief that it is ethical to refer an LGB client. © 2015 American Association for Marriage and Family Therapy.

Borderline Personality Disorder and the Effects of Instructed Emotional Avoidance or Acceptance in Daily Life.

PubMed

Chapman, Alexander L; Rosenthal, M Zachary; Dixon-Gordon, Katherine L; Turner, Brianna J; Kuppens, Peter

2017-08-01

This study examined the effects of avoidance- versus acceptance-oriented emotion regulation instructions among individuals with borderline personality disorder (BPD; n = 48), major depressive disorder (MDD; n = 54), and non-psychiatric controls (NPC; n = 50) using ecological momentary assessment. Participants were randomly assigned to either accept or avoid negative emotions, and monitored their moods, urges, and distress tolerance several times per day over 6 days. Avoidance instructions resulted in reduced negative affect and urges for maladaptive behaviors uniquely among BPD participants. Together with past research, and consistent with treatment approaches emphasizing the short-term use of skills to avoid or distract from emotions (e.g., DBT; Linehan, 1993b, 2015), these findings suggest that avoidance of negative emotions may have temporary benefits for individuals with BPD. Acceptance-oriented strategies may take longer or may require more extensive training to be beneficial for emotional functioning in everyday life in BPD.

Role of orientation reference selection in motion sickness, supplement 2S

Peterka, Robert J.; Black, F. Owen

1987-01-01

Previous experiments with moving platform posturography have shown that different people have varying abilities to resolve conflicts among vestibular, visual, and proprioceptive sensory signals. The conceptual basis of the present proposal hinges on the similarities between the space motion sickness problem and the sensory orientation reference selection problems associated with benign paroxysmal positional vertigo (BPPV) syndrome. These similarities include both etiology related to abnormal vertical canal-otolith function, and motion sickness initiating events provoked by pitch and roll head movements. The objectives are to explore and quantify the orientation reference selection abilities of subjects and the relation of this selection to motion sickness in humans. The overall objectives are to determine: if motion sickness susceptibility is related to sensory orientation reference selection abilities of subjects; if abnormal vertical canal-otolith function is the source of abnormal posture control strategies and if it can be quantified by vestibular and oculomotor reflex measurements, and if it can be quantified by vestibular and oculomotor reflex measurements; and quantifiable measures of perception of vestibular and visual motion cues can be related to motion sickness susceptibility and to orientation reference selection ability.

Dominant negative RPW8.2 fusion proteins reveal the importance of haustorium-oriented protein trafficking for resistance against powdery mildew in Arabidopsis.

PubMed

Zhang, Qiong; Berkey, Robert; Pan, Zhiyong; Wang, Wenming; Zhang, Yi; Ma, Xianfeng; King, Harlan; Xiao, Shunyuan

2015-01-01

Powdery mildew fungi form feeding structures called haustoria inside epidermal cells of host plants to extract photosynthates for their epiphytic growth and reproduction. The haustorium is encased by an interfacial membrane termed the extrahaustorial membrane (EHM). The atypical resistance protein RPW8.2 from Arabidopsis is specifically targeted to the EHM where RPW8.2 activates haustorium-targeted (thus broad-spectrum) resistance against powdery mildew fungi. EHM-specific localization of RPW8.2 suggests the existence of an EHM-oriented protein/membrane trafficking pathway during EHM biogenesis. However, the importance of this specific trafficking pathway for host defense has not been evaluated via a genetic approach without affecting other trafficking pathways. Here, we report that expression of EHM-oriented, nonfunctional RPW8.2 chimeric proteins exerts dominant negative effect over functional RPW8.2 and potentially over other EHM-localized defense proteins, thereby compromising both RPW8.2-mediated and basal resistance to powdery mildew. Thus, our results highlight the importance of the EHM-oriented protein/membrane trafficking pathway for host resistance against haustorium-forming pathogens such as powdery mildew fungi.

Anisotropic Negative Thermal Expansion Behavior of the As-Fabricated Ti-Rich and Equiatomic Ti-Ni Alloys Induced by Preferential Grain Orientation

NASA Astrophysics Data System (ADS)

Zhao, Zhong-Xun; Ma, Xiao; Cao, Shan-Shan; Ke, Chang-Bo; Zhang, Xin-Ping

2017-12-01

The present study focuses on the anisotropic negative thermal expansion (NTE) behaviors of Ti-rich (Ti54Ni46) and equiatomic Ti-Ni (Ti50Ni50) alloys fabricated by vacuum arc melting and without subsequent plastic deformation. Both alloys exhibit NTE responses in vertical and horizontal directions, and the total strains and CTEs of the NTE stage along the two mutually perpendicular measuring directions are obviously different, indicating obvious anisotropic NTE behavior of the alloys. Besides, the numerical differences between the starting temperature of NTE and austenitic transformation and between the finishing temperature of NTE and austenitic transformation are very small, which indicates that an apparent relationship exists between the NTE behavior and the phase transformation. The microstructure in the vertical cross sections shows obviously preferential orientation characteristics: Ti2Ni phases of both alloys grow along the vertical direction, and B19' martensite of Ti50Ni50 alloy has distinct preferential orientation, which results from a large temperature gradient between the top and the bottom of the button ingots during solidification. The microstructure with preferential orientation induces the anisotropic NTE behavior of the samples.

Transference and insight in psychotherapy with gay and bisexual male clients: the role of sexual orientation identity integration.

PubMed

Mohr, Jonathan J; Fuertes, Jairo N; Stracuzzi, Thomas I

2015-03-01

Clinical writing has suggested that the therapeutic process and relationship in work with lesbian, gay, and bisexual clients may be influenced by the extent to which clients have accepted their sexual orientation and developed a social network supportive of their sexual orientation, a construct we refer to as sexual orientation identity integration. The present cross-sectional study investigated this proposition by examining the identity integration ratings of 90 gay and bisexual male clients in relation to elements of treatment as rated by both the therapist (insight, negative transference, working alliance, session depth, and client improvement) and client (working alliance, session depth, and client improvement). Participants were male-male therapy dyads recruited from lesbian, gay, and bisexual-affirming practices. Client identity integration was negatively associated with transference, and positively associated with ratings of insight, alliance, depth, and improvement. Insight, but not transference, uniquely mediated the positive association between identity integration and most indicators of therapeutic quality. Results from an exploratory model suggested that transference may indirectly influence therapeutic quality by serving as a barrier to insight.

2013-09-01

Research is needed to explore conceptual change in relation to achievement goal orientations and depth of processing. To address this need, we examined relations between achievement goals, use of deep versus shallow processing strategies, and conceptual change learning using a think-aloud protocol. Seventy-three undergraduate students were assessed on their prior knowledge and misconceptions about Newtonian mechanics, and then reported their achievement goals and participated in think-aloud protocols while reading Newtonian physics texts. A mastery-approach goal orientation positively predicted deep processing strategies, shallow processing strategies, and conceptual change. In contrast, a performance-approach goal orientation did not predict either of the processing strategies, but negatively predicted conceptual change. A performance-avoidance goal orientation negatively predicted deep processing strategies and conceptual change. Moreover, deep and shallow processing strategies positively predicted conceptual change as well as recall. Finally, both deep and shallow processing strategies mediated relations between mastery-approach goals and conceptual change. Results provide some support for Dole and Sinatra's (1998) Cognitive Reconstruction of Knowledge Model of conceptual change but also challenge specific facets with regard to the role of depth of processing in conceptual change. © 2012 The British Psychological Society.

Couple-Oriented Education and Support Intervention for Osteoarthritis: Effects on Spouses’ Support and Responses to Patient Pain

The purpose of this study was to determine whether a couple-oriented education and support intervention for osteoarthritis was more efficacious than a similar patient-oriented intervention in terms of enhancing spouses’ support of patients and their positive and negative responses to patient pain. Repeated-measures analyses of covariance with the completers sample (N = 103 dyads) showed that at the postintervention assessment, patients in the couple-oriented intervention reported a greater decrease in their spouses’ punishing responses (e.g., anger, irritation) than did patients in the patient-oriented intervention. In addition, a trend effect was observed in regard to the advantage of couple-oriented intervention for increasing spouses’ attempts to distract patients from their pain. At the 6-month follow-up, patients in the couple-oriented intervention reported greater increased spouse support than those in the patient-oriented intervention. Findings illustrate the value of examining change in specific types of marital interactions targeted in a couples intervention, and the need to strengthen the impact of future couple-oriented interventions.

Effect of negative mechanical stress on the orientation of myosin cross-bridges in muscle fibers.

PubMed Central

Burghardt, T P; Ajtai, K

1989-01-01

The effect of positive and negative stress on myosin cross-bridge orientation in glycerinated muscle fibers was investigated by using fluorescence polarization spectroscopy of the emission from the covalent label tetramethyl-rhodamine-5-(and -6)-iodoacetamide (IATR) specifically modifying sulfhydryl one (SH1) on the myosin heavy chain. Positive tension was applied by stretching the fiber in rigor. Negative tension was applied in two steps by using a protocol introduced by Goldman et al. [Goldman, Y. E., McCray, J. A. & Vallette, D. P. (1988) J. Physiol. (London) 398, 75P]: relaxing a fiber at resting length and stretching it until the relaxed tension is appreciable and then placing the fiber in rigor and releasing the tension onto the rigor cross-bridges. We found, as have others, that positive tension has no effect on the fluorescence polarization spectrum from the SH1-bound probe, indicating that the cross-bridge does not rotate under these conditions. Negative tension, however, causes a change in the fluorescence polarization spectrum that indicates a probe rotation. The changes in the polarization spectrum from negative stress are partially reversed by the subsequent application of positive stress. It appears that negative tension strains the cross-bridge, or the cross-bridge domain containing SH1, and causes it to rotate. Images PMID:2526336

Task decomposition for a multilimbed robot to work in reachable but unorientable space

NASA Technical Reports Server (NTRS)

Su, Chau; Zheng, Yuan F.

1991-01-01

Robot manipulators installed on legged mobile platforms are suggested for enlarging robot workspace. To plan the motion of such a system, the arm-platform motion coordination problem is raised, and a task decomposition is proposed to solve the problem. A given task described by the destination position and orientation of the end effector is decomposed into subtasks for arm manipulation and for platform configuration, respectively. The former is defined as the end-effector position and orientation with respect to the platform, and the latter as the platform position and orientation in the base coordinates. Three approaches are proposed for the task decomposition. The approaches are also evaluated in terms of the displacements, from which an optimal approach can be selected.

Effect of triangular element orientation on finite element solutions of the Helmholtz equation

NASA Technical Reports Server (NTRS)

Baumeister, K. J.

1986-01-01

The Galerkin finite element solutions for the scalar homogeneous Helmholtz equation are presented for no reflection, hard wall, and potential relief exit terminations with a variety of triangular element orientations. For this group of problems, the correlation between the accuracy of the solution and the orientation of the linear triangle is examined. Nonsymmetric element patterns are found to give generally poor results in the model problems investigated, particularly for cases where standing waves exist. For a fixed number of vertical elements, the results showed that symmetric element patterns give much better agreement with corresponding exact analytical results. In laminated wave guide application, the symmetric pyramid pattern is convenient to use and is shown to give excellent results.

When is success not satisfying? Integrating regulatory focus and approach/avoidance motivation theories to explain the relation between core self-evaluation and job satisfaction.

2013-03-01

Integrating implications from regulatory focus and approach/avoidance motivation theories, we present a framework wherein motivational orientations toward positive (approach motivation orientation) or negative (avoidance motivation orientation) stimuli interact with workplace success to mediate the relation of core self-evaluation (CSE) with job satisfaction. Using data collected from supervisor-subordinate dyads (Sample 1) and time-lagged data (Sample 2), we found that the results from two studies indicated that the interaction of workplace success and avoidance motivation orientation mediated relations of CSE with job satisfaction. Although approach motivation orientation did not interact with workplace success, it did mediate the CSE-job satisfaction relation on its own. Implications for the CSE and approach/avoidance literatures are discussed.

Caring across boundaries versus keeping boundaries intact: links between moral values and interpersonal orientations.

PubMed

Niemi, Laura; Young, Liane

2013-01-01

Prior work has established robust diversity in the extent to which different moral values are endorsed. Some people focus on values related to caring and fairness, whereas others assign additional moral weight to ingroup loyalty, respect for authority and established hierarchies, and purity concerns. Five studies explore associations between endorsement of distinct moral values and a suite of interpersonal orientations: Machiavellianism, prosocial resource distribution, Social Dominance Orientation, and reported likelihood of helping and not helping kin and close friends versus acquaintances and neighbors. We found that Machiavellianism (Studies 1, 3, 4, 5) (e.g., amorality, controlling and status-seeking behaviors) and Social Dominance Orientation (Study 4) were negatively associated with caring values, and positively associated with valuation of authority. Those higher in caring values were more likely to choose prosocial resource distributions (Studies 2, 3, 4) and to report reduced likelihood of failing to help kin/close friends or acquaintances (Study 4). Finally, greater likelihood of helping acquaintances was positively associated with all moral values tested except authority values (Study 4). The current work offers a novel approach to characterizing moral values and reveals a striking divergence between two kinds of moral values in particular: caring values and authority values. Caring values were positively linked with prosociality and negatively associated with Machiavellianism, whereas authority values were positively associated with Machiavellianism and Social Dominance Orientation.

2014-01-01

Multidisciplinary research has supported a relationship between adolescent future orientation (the ability to set future goals and plans) and positive adolescent health and development outcomes. Many preventive strategies - for example, contracepting, exercising - are based on taking actions in the present to avoid unwanted or negative future consequences. However, research has been hampered by unclear and often divergent conceptualizations of the future orientation construct. The present paper aims to integrate previous conceptual and operational definitions into a conceptual framework that can inform programs and services for youth and efforts to evaluate future orientation as a target for intervention. Recommendations focus on furthering the study of the construct through measurement synthesis as well as studies of the normative development of future orientation. Also suggested is the need to pair environmental intervention strategies with individual level efforts to improve future orientation in order to maximize benefits.

Family factors related to children's intrinsic/extrinsic motivational orientation and academic performance.

PubMed

Ginsburg, G S; Bronstein, P

1993-10-01

This study examined 3 familial factors--parental surveillance of homework, parental reactions to grades, and general family style--in relation to children's motivational orientation and academic performance. Family, parent, and child measures were obtained in the home from 93 fifth graders and their parents. Teachers provided a measure of classroom motivational orientation, and grades and achievement scores were obtained from school records. Higher parental surveillance of homework, parental reactions to grades that included negative control, uninvolvement, or extrinsic reward, and over- and undercontrolling family styles were found to be related to an extrinsic motivational orientation and to lower academic performance. On the other hand, parental encouragement in response to grades children received was associated with an intrinsic motivational orientation, and autonomy-supporting family styles were associated with intrinsic motivation and higher academic performance. In addition, socioeconomic level was a significant predictor of motivational orientation and academic performance.

In the present study, we examined the impact of cultural value orientations (i.e., the personally oriented value of individualism, and the socially oriented values of collectivism, familism, romanticism, and spiritualism) on accommodation (i.e., voice and loyalty, rather than exit and neglect, responses to partners' anger or criticism) in heterosexual and gay relationships; and we examined the impact of internalized homophobia (i.e., attitudes toward self, other, and disclosure) on accommodation specifically in gay relationships. A total of 262 heterosexuals (102 men and 162 women) and 857 gays (474 men and 383 women) participated in the present study. Consistent with hypotheses, among heterosexuals and gays, socially oriented values were significantly and positively related to accommodation (whereas the personally oriented value of individualism was unrelated to accommodation); and among gays in particular, internalized homophobia was significantly and negatively related to accommodation. Implications for the study of heterosexual and gay relationships are discussed.

The Main and Interactive Effects of Maternal Interpersonal Emotion Regulation and Negative Affect on Adolescent Girls' Borderline Personality Disorder Symptoms.

2016-06-01

The transaction of adolescent's expressed negative affect and parental interpersonal emotion regulation are theoretically implicated in the development of borderline personality disorder (BPD). Although problem solving and support/validation are interpersonal strategies that foster emotion regulation, little is known about whether these strategies are associated with less BPD severity among adolescents. Adolescent girls (age 16; N = 74) and their mothers completed a conflict discussion task, and maternal problem solving, support/validation, and girls' negative affect were coded. Girls' BPD symptoms were assessed at four time points. A 3-way interaction of girls' negative affect, problem solving, and support/validation indicated that girls' negative affect was only associated with BPD severity in the context of low maternal support/validation and high maternal problem solving. These variables did not predict changes in BPD symptoms over time. Although high negative affect is a risk for BPD severity in adolescent girls, maternal interpersonal emotion regulation strategies moderate this link. Whereas maternal problem solving coupled with low support/validation is associated with a stronger negative affect-BPD relation, maternal problem solving paired with high support/validation is associated with an attenuated relationship.

Approach/avoidance motivation, message framing and skin cancer prevention: a test of the congruency hypothesis.

PubMed

Hevey, David; Dolan, Michelle

2014-08-01

The congruency hypothesis posits that approach-orientated individuals are persuaded to engage in prevention behaviours by positively framed messages; conversely, negatively framed messages are more persuasive in encouraging those who are avoidance-orientated. A 2 (frame: loss vs gain) × 2 (motivation: avoidance vs approach) design examined the effects of skin cancer information on sun-protective intentions and free sunscreen sample requests among 533 young adults. Gain-framed messages had the strongest effect on sun-protective intentions for approach-oriented individuals, whereas loss-framed messages had the strongest effect on avoidance-oriented individuals. Message framing effects on precautionary sun behaviour intentions were moderated by motivational differences. © The Author(s) 2013.

Health-related quality of life in patients with hepatocellular carcinoma: the mediation effects of illness perceptions and coping.

2013-06-01

The aims of this study were to explore health-related quality of life (HRQOL) in patients with hepatocellular carcinoma (HCC). We report the following: (1) differences in HRQOL between patients with HCC and the general population; (2) significant physical and psychological predictors of HRQOL; and (3) mediation effects of illness perceptions and coping on HRQOL. Patients with HCC (n = 286) from Taiwan completed standardized measures of HRQOL, illness perception (cognitive representations, emotional representations and illness comprehensibility) and coping (emotion-oriented and problem-orientation coping). Demographic and physical variables were also collected. Patients with HCC had worse global HRQOL, physical, role, cognitive and social functioning, but better emotional functioning than the general population. Physical variables and cognitive representation were significant predictors of global HRQOL, physical functioning and emotional functioning. Cognitive representation mediated the relationships between physical variables and global HRQOL, physical functioning and emotional functioning, but coping only mediated the relationship between cognitive representation and global HRQOL. The results suggest that physical variables have direct effects on global HRQOL and physical functioning, but there were also partial mediations through cognitive representation. The effect of physical variables on emotional functioning was mediated through cognitive and emotional representations. Patients with better performance status and positive illness perceptions tended to report better HRQOL, but those with negative illness perceptions and who used more emotion-oriented coping had worse HRQOL. Limitations of the work associated with use of theory and measures developed in Europe and the US are discussed, as are the clinical implications for patients with HCC.

The Case/Care Manager (CCM) is a new position for in the Italian National Health Service scenario. Job satisfaction plays a key role for the CCM to engage in his work, accomplishing it in a complete. Nurses' job satisfaction is a complex construct and many different variables can influence it: personal characteristics, cultural characteristic, social characteristic, organizational characteristic, and environmental characteristic. The main aim of this study is to assess the job satisfaction in a sample of CCM and to assess if and how Social Variables (organizational climate and health) and Individual (socio-demographic variables, coping strategies, emotion regulation) relate to the CCM job satisfaction. This study has a quantitative exploratory cross-sectional design. Participants were Nurse CCM with or without specific training who filled a battery of questionnaires : Job Satisfaction Survey (JSS) , section three of ICONAS questionnaire, section five of the Multidimensional Organizational Health Questionnaire (MOHQ), anamnestic sheet, Coping Orientation to the Problems Experienced (COPE-NVI-25), and Emotion Regulation Questionnaire (ERQ). The battery was administered online on the website of Italian Case Manager, Italian Association of Care Manager, and IPASVI Colleges. It was also distributed during the National Congress for Case Manager in Padua. 103 participants took part in the study. The total mean score of JSS was 117,28 (S.D.=21,12). The emotional regulation strategy most used was the "Cognitive Response", and the most used Coping strategy was "Problem Oriented". There were significant correlations between JSS and Social variables in the total score (ICONAS r=.574 p<0.01; MOHQ (positive indicators) r=.608 p<0.01; MOHQ (negative indicators) r=-.634 p <0.01) and in its subscales. There were also significant correlations between JSS subscales and Individual variables (COPE and ERQ). Participants with a specific training tend to use the emotion regulation strategy "Negative interpretation self-oriented" (U 910.500 p<0.005) and "Distraction" (U 885.000 p<0.005) more than those without specific training. The same significant difference was found in JSS pay (t=-2,48 per p<0.05) and JSS Fringe Benefits (t=-2,07 per p<0.05). The CCM job satisfaction seems to be ambivalent. It seems to be not entirely polarized on presence/absence, but rather still in a gray area. organizational climate and health influence significantly the overall perception of job satisfaction and its different areas. The most "avoiding" emotional regulation strategies, seem to negatively affect the perception of satisfaction. Emotional regulation and coping strategies related to challenges focusing and management, along with the individual perception of collaboration, positively influence satisfaction. Participants who underwent a specific CCM training, committing themselves financially and personally, perceive less job satisfaction when their role is not recognized in terms of pay. This study showed that that the main strategies used to regulate emotions are the Cognitive Response and the Social Contact. We suggest that further studies could be made to define the links between individual strategies and the presence of chronic distress and we suggest that a specific training on coping and emotion regulation may be implemented in graduation and post-graduation courses.

Neuroscience Investigations: An Overview of Studies Conducted

NASA Technical Reports Server (NTRS)

Reschke, Millard F.

1999-01-01

The neural processes that mediate human spatial orientation and adaptive changes occurring in response to the sensory rearrangement encountered during orbital flight are primarily studied through second and third order responses. In the Extended Duration Orbiter Medical Project (EDOMP) neuroscience investigations, the following were measured: (1) eye movements during acquisition of either static or moving visual targets, (2) postural and locomotor responses provoked by unexpected movement of the support surface, changes in the interaction of visual, proprioceptive, and vestibular information, changes in the major postural muscles via descending pathways, or changes in locomotor pathways, and (3) verbal reports of perceived self-orientation and self-motion which enhance and complement conclusions drawn from the analysis of oculomotor, postural, and locomotor responses. In spaceflight operations, spatial orientation can be defined as situational awareness, where crew member perception of attitude, position, or motion of the spacecraft or other objects in three-dimensional space, including orientation of one's own body, is congruent with actual physical events. Perception of spatial orientation is determined by integrating information from several sensory modalities. This involves higher levels of processing within the central nervous system that control eye movements, locomotion, and stable posture. Spaceflight operational problems occur when responses to the incorrectly perceived spatial orientation are compensatory in nature. Neuroscience investigations were conducted in conjunction with U. S. Space Shuttle flights to evaluate possible changes in the ability of an astronaut to land the Shuttle or effectively perform an emergency post-landing egress following microgravity adaptation during space flights of variable length. While the results of various sensory motor and spatial orientation tests could have an impact on future space flights, our knowledge of sensorimotor adaptation to spaceflight is limited, and the future application of effective countermeasures depends, in large part, on the results from appropriate neuroscience investigations. Therefore, the objective of the neuroscience investigations could have a negative effect on mission success. The Neuroscience Laboratory, Johnson Space Center (JSC), implemented three integrated Detailed Supplementary Objectives (DSO) designed to investigate spatial orientation and the associated compensatory responses as a part of the EDOMP. The four primary goals were (1) to establish a normative database of vestibular and associated sensory changes in response to spaceflight, (2) to determine the underlying etiology of neurovestibular and sensory motor changes associated with exposure to microgravity and the subsequent return to Earth, (3) to provide immediate feedback to spaceflight crews regarding potential countermeasures that could improve performance and safety during and after flight, and (4) to take under consideration appropriate designs for preflight, in-flight, and postflight countermeasures that could be implemented for future flights.

Community service contracting for older people in urban China: a case study in Guangdong Province.

Contracting of community services to non-governmental service-providing organisations - mainly social work agencies - is an emerging phenomenon and a social innovation with regard to delivering community services in urban China. Contracting of community services for the older person, which is the focus of this study, is embedded in the macro context of the development of social service contracting in China. Qualitative research techniques, including document analysis, case study, participant observation and in-depth interviews, were adopted for this study. Nine government officials, three staff working in Community Residents' Committees, 15 staff working in social work agencies and 41 older people were interviewed in an effort to understand the impact and challenges of community service contracting in urban China. The findings showed that the involvement of social work agencies in the community service provision system results in integration of community resources, expansion of service coverage and enhancement of older people's access to community services. However, several problems may impede the development of community service provision in the context of contracting in China. These include purchaser-oriented rather than user-oriented service provision, older people's negative attitude towards social work services, inappropriate performance measurement, reliance of non-government organisations on government funding and ambiguous definition of community services.

College student drinking is a major public health concern and can result in a range of negative consequences, from acute health risks to decreased academic performance and drop out. Harm reduction interventions have been developed to reduce problems associated with drinking but there is a need to identify specific risk/protective factors related to academic performance among college drinkers. Behavioral economics suggests that chronic alcohol misuse reflects a dysregulated behavioral process or reinforcer pathology-alcohol is overvalued and the value of prosocial rewards are sharply discounted due, in part, to their delay. This study examined delay discounting, consideration of future consequences (CFC) and protective behavioral strategies (PBS) as predictors of academic success (grade point average; GPA) and engagement (time devoted to academic activities) among 393 college drinkers (61% female). In multivariate models, PBS were associated with greater academic engagement, but were not with academic success. Lower discounting of delayed rewards and greater CFC were associated with both academic success and engagement among drinkers. Previous research suggests that future time orientation is malleable, and the current results provide support for efforts to enhance future time orientation as part of alcohol harm-reduction approaches.

Questionnaire-based research has shown that parents exert a powerful influence on and are profoundly influenced by living with a child with chronic pain. Examination of parents' pain narratives through an observational lens offers an alternative approach to understanding the complexity of pediatric chronic pain; however, the narratives of parents of youth with chronic pain have been largely overlooked. The present study aimed to characterize the vulnerability-based and resilience-based aspects of the pain narratives of parents of youth with chronic pain. Pain narratives of 46 parents were recorded during the baseline session as part of 2 clinical trials evaluating a behavioral intervention for parents of youth with chronic pain. The narratives were coded for aspects of pain-related vulnerability and resilience. Using exploratory cluster analysis, 2 styles of parents' pain narratives were identified. Distress narratives were characterized by more negative affect and an exclusively unresolved orientation toward the child's diagnosis of chronic pain, whereas resilience narratives were characterized by positive affect and a predominantly resolved orientation toward the child's diagnosis. Preliminary support for the validity of these clusters was provided through our finding of differences between clusters in parental pain catastrophizing about child pain (helplessness). Findings highlight the multidimensional nature of parents' experience of their child's pain problem. Clinical implications in terms of assessment and treatment are discussed.

A cylindrical shell with an arbitrarily oriented crack

The general problem of a shallow shell with constant curvatures is considered. It is assumed that the shell contains an arbitrarily oriented through crack and the material is specially orthotropic. The nonsymmetric problem is solved for arbitrary self equilibrating crack surface tractions, which, added to an appropriate solution for an uncracked shell, would give the result for a cracked shell under most general loading conditions. The problem is reduced to a system to five singular integral equations in a set of unknown functions representing relative displacements and rotations on the crack surfaces. The stress state around the crack tip is asymptotically analyzed and it is shown that the results are identical to those obtained from the two dimensional in plane and antiplane elasticity solutions. The numerical results are given for a cylindrical shell containing an arbitrarily oriented through crack. Some sample results showing the effect of the Poisson's ratio and the material orthotropy are also presented. Previously annunced in STAR as N83-16783

Cooperation between mental health professionals and doctors in a Balint-oriented supervision group.

PubMed

Keinänen, M

2001-01-01

A Balint-oriented supervision group for physicians is described concentrating on the study of the patient-doctor relationship, the recognition and diagnosis of psychiatric problems, and the planning of psychiatric treatment. The group includes five general practitioners, a gynecologist, a dermatologist, a psychiatrist and a psychologist, who have met once a month for an hour over a period of 12 years. Interaction between the physicians and the mental health professionals is illustrated by two clinical examples. The group helps the physician recognize, tolerate and use his countertransference feelings, and facilitates the examination and treatment of patients suffering from psychiatric problems. In Balint-oriented group work, the focus can be moved from physical symptoms to include observation of the patient's emotional life and significant object relations, to the factors that are crucial for his psychological balance. This kind of holistic observation in the examination and treatment of psychiatric problems is as important as appropriate laboratory investigations in the diagnosis and care of physical diseases.

2015-01-01

We administered the Dutch Multidimensional Perfectionism Scale of Hewitt and Flett (1991, 2004) in a large student sample (N = 959) and performed a confirmatory factor analysis to test the factorial structure proposed by the original authors. The existence of a method factor referring to the negatively keyed items in the questionnaire was investigated by including it in the tested models. Next, we investigated how the 3 perfectionism dimensions are associated with the Five-factor model (FFM) of personality. The 3-factor structure originally observed by the authors was confirmed, at least when a method factor that refers to the negatively keyed items was included in the model. Self-oriented and socially prescribed perfectionism were both distinguished by low extraversion and low emotional stability. Self-oriented perfectionism's positive relationship with both conscientiousness and openness to experience differentiated the 2 perfectionism dimensions from each other. Other-oriented perfectionism was not well-characterized by the Big Five personality traits.

ABSTRACTThis article presents two studies dealing with ageism. The objective of the first study was to adapt to French language and validate the Fraboni of Ageism Scale-Revised (FSA-R) which contains 23 items, while the objective of the second study was to test a structural model containing ageism as measured by the FSA-R and the "Big Three": empathy, social dominance orientation, and dogmatism, controlled for by sex and age. The results of the first study (n = 323) generated a version of the FSA-R comprising 14 items, of which the psychometric properties were very satisfactory. Using structural equation modelling and bootstrap procedure, the results of the second study (n = 284) showed a direct negative and significant effect of empathy on agism. They also showed that this negative effect was mediated by dogmatism and social dominance orientation, which both exerted a positive effect on ageism.

1992-01-01

Freshmen (N = 556) at a large eastern private university were administered a questionnaire during the first week of classes. A social learning perspective was used to examine the effects of gender, race (Asian, black, and white), religion (Catholic, Jewish, and Protestant), and political orientation (liberal and conservative) on four areas of sex role ideology--traditional attitudes toward female sexuality, justification of male dominance, negative attitudes toward homosexuality, and attitudes toward feminism. Although all four independent variables produced a significant effect on at least one measure of sex role ideology, religion and political orientation produced significant differences on all four sex role measures. Liberals as compared to conservatives and Jews as compared to Protestants were less traditional in their attitudes toward female sexuality, less accepting of male dominance and negative attitudes toward homosexuality, and more accepting of feminist attitudes. The results support the view that entering freshmen have established sex role belief systems that tend to be organized around constellations of traditional/conservative versus egalitarian/liberal attitudes.

Meta-analytic methods were used to analyze 179 effect sizes retrieved from 32 research reports on the implications that sexual minority stress may have for same-sex relationship well-being. Sexual minority stress (aggregated across different types of stress) was moderately and negatively associated with same-sex relationship well-being (aggregated across different dimensions of relationship well-being). Internalized homophobia was significantly and negatively associated with same-sex relationship well-being, whereas heterosexist discrimination and sexual orientation visibility management were not. Moreover, the effect size for internalized homophobia was significantly larger than those for heterosexist discrimination and sexual orientation visibility management. Sexual minority stress was significantly and negatively associated with same-sex relationship quality but not associated with closeness or stability. Sexual minority stress was significantly and negatively associated with relationship well-being among same-sex female couples but not among same-sex male couples. The current status of research approaches in this field was also summarized and discussed.

Ultra-thin passivating film induced by vinylene carbonate on highly oriented pyrolytic graphite negative electrode in lithium-ion cell

NASA Astrophysics Data System (ADS)

Matsuoka, O.; Hiwara, A.; Omi, T.; Toriida, M.; Hayashi, T.; Tanaka, C.; Saito, Y.; Ishida, T.; Tan, H.; Ono, S. S.; Yamamoto, S.

We investigated the influence of vinylene carbonate, as an additive molecule, on the decomposition phenomena of electrolyte solution [ethylene carbonate (EC)—ethyl methyl carbonate (EMC) (1:2 by volume) containing 1 M LiPF 6] on a highly oriented pyrolytic graphite (HOPG) negative electrode by using cyclic voltammetry (CV) and atomic force microscopy (AFM). Vinylene carbonate deactivated reactive sites (e.g. radicals and oxides at the defects and the edge of carbon layer) on the cleaved surface of the HOPG negative electrode, and prevented further decomposition of the other solvents there. Further, vinylene carbonate induced an ultra-thin film (less than 1.0 nm in thickness) on the terrace of the basal plane of the HOPG negative electrode, and this film suppressed the decomposition of electrolyte solution on the terraces of the basal plane. We consider that this ultra-thin passivating film is composed of a reduction product of vinylene carbonate (VC), and might have a polymer structure. These induced effects might explain how VC improves the life performance of lithium-ion cells.

Robust Vision-Based Pose Estimation Algorithm for AN Uav with Known Gravity Vector

NASA Astrophysics Data System (ADS)

Kniaz, V. V.

2016-06-01

Accurate estimation of camera external orientation with respect to a known object is one of the central problems in photogrammetry and computer vision. In recent years this problem is gaining an increasing attention in the field of UAV autonomous flight. Such application requires a real-time performance and robustness of the external orientation estimation algorithm. The accuracy of the solution is strongly dependent on the number of reference points visible on the given image. The problem only has an analytical solution if 3 or more reference points are visible. However, in limited visibility conditions it is often needed to perform external orientation with only 2 visible reference points. In such case the solution could be found if the gravity vector direction in the camera coordinate system is known. A number of algorithms for external orientation estimation for the case of 2 known reference points and a gravity vector were developed to date. Most of these algorithms provide analytical solution in the form of polynomial equation that is subject to large errors in the case of complex reference points configurations. This paper is focused on the development of a new computationally effective and robust algorithm for external orientation based on positions of 2 known reference points and a gravity vector. The algorithm implementation for guidance of a Parrot AR.Drone 2.0 micro-UAV is discussed. The experimental evaluation of the algorithm proved its computational efficiency and robustness against errors in reference points positions and complex configurations.

2011-01-01

Purpose We use different methods to train our undergraduates. The patient-oriented problem-solving (POPS) system is an innovative teaching–learning method that imparts knowledge, enhances intrinsic motivation, promotes self learning, encourages clinical reasoning, and develops long-lasting memory. The aim of this study was to develop POPS in teaching pathology, assess its effectiveness, and assess students’ preference for POPS over didactic lectures. Method One hundred fifty second-year MBBS students were divided into two groups: A and B. Group A was taught by POPS while group B was taught by traditional lectures. Pre- and posttest numerical scores of both groups were evaluated and compared. Students then completed a self-structured feedback questionnaire for analysis. Results The mean (SD) difference in pre- and post-test scores of groups A and B was 15.98 (3.18) and 7.79 (2.52), respectively. The significance of the difference between scores of group A and group B teaching methods was 16.62 (P < 0.0001), as determined by the z-test. Improvement in post-test performance of group A was significantly greater than of group B, demonstrating the effectiveness of POPS. Students responded that POPS facilitates self-learning, helps in understanding topics, creates interest, and is a scientific approach to teaching. Feedback response on POPS was strong in 57.52% of students, moderate in 35.67%, and negative in only 6.81%, showing that 93.19% students favored POPS over simple lectures. Conclusion It is not feasible to enforce the PBL method of teaching throughout the entire curriculum; However, POPS can be incorporated along with audiovisual aids to break the monotony of dialectic lectures and as alternative to PBL.

The aim of the present study was to compare the experience elderly and younger patients in terms of emotional status, disease perception, methods of coping with the end-stage renal disease (ESRD) stress, and health-related quality of life in 2 different settings of renal replacement therapy: hemodialysis (HD) and continuous ambulatory peritoneal dialysis programs (CAPD). Specifically, we hypothesized that younger people will more frequently use goal-oriented strategies to cope with illness-related stress and elderly patients will use more strategies related to the control of emotion. A total of 69 HD patients, 40 CAPD patients, and 89 healthy volunteers were analyzed. The Situation and Trait Anxiety Inventory, the Profile of Mood States, the Cognitive Stress Appraisal Questionnaire, and the Nottingham Health Profile were used to assess anxiety, long-term emotional status, coping mechanisms, and health-related quality of life. Data were collected on several biochemical and demographic variables. Our study revealed that younger and elderly people on dialysis faced quite different problems. Younger people in both RRT groups had statistically higher assessment of ESRD as loss or challenge and they more frequently used distractive and emotional preoccupation coping strategies. Depression, confusion, and bewilderment dominate the emotional status of both patient populations, especially in the younger cohort. Both HD(young) and CAPD(young) patients complained more about lack of energy, mobility limitations, and sleep disturbances as compared to their elderly HD and CAPD counterparts. There are different needs and problems in younger and elderly patients on renal replacement therapy. Younger people required more ESRD-oriented support to relieve their health-related complaints to the level observed in their peers and needed extensive psychological assistance in order to cope with negative emotions related to their disease.

Family Conflict, Mood, and Adolescents’ Daily School Problems: Moderating Roles of Internalizing and Externalizing Symptoms

Timmons, Adela C.; Margolin, Gayla

2014-01-01

Using daily diary data, this study examined cross-day associations between family conflict and school problems and tested mediating effects of daily negative mood and moderating effects of psychological symptoms. For 2 weeks, parents and adolescents (N = 106; mean age = 15.4) reported daily conflict; adolescents reported daily negative mood and school problems. Results indicated bidirectional, multi-day spillover between parent-adolescent conflict and school problems with daily negative mood statistically accounting for spillover both within and across days. Externalizing symptoms strengthened links between father-adolescent conflict and school problems, whereas depressive and anxious symptoms strengthened links between parent-adolescent conflict and daily negative mood. By demonstrating cross-domain transmission of daily problems, these findings highlight the salience of everyday events as possible intervention targets. PMID:25346538

An algorithm to improve diagnostic accuracy in diabetes in computerised problem orientated medical records (POMR) compared with an established algorithm developed in episode orientated records (EOMR).

An algorithm that detects errors in diagnosis, classification or coding of diabetes in primary care computerised medial record (CMR) systems is currently available. However, this was developed on CMR systems that are episode orientated medical records (EOMR); and do not force the user to always code a problem or link data to an existing one. More strictly problem orientated medical record (POMR) systems mandate recording a problem and linking consultation data to them. To compare the rates of detection of diagnostic accuracy using an algorithm developed in EOMR with a new POMR specific algorithm. We used data from The Health Improvement Network (THIN) database (N = 2,466,364) to identify a population of 100,513 (4.08%) patients considered likely to have diabetes. We recalibrated algorithms designed to classify cases of diabetes to take account of that POMR enforced coding consistency in the computerised medical record systems [In Practice Systems (InPS) Vision] that contribute data to THIN. We explored the different proportions of people classified as having type 1 diabetes mellitus (T1DM) or type 2 diabetes mellitus (T2DM) and with diabetes unclassifiable as either T1DM or T2DM. We compared proportions using chi-square tests and used Tukey's test to compare the characteristics of the people in each group. The prevalence of T1DM using the original EOMR algorithm was 0.38% (9,264/2,466,364), and for T2DM 3.22% (79,417/2,466,364). The prevalence using the new POMR algorithm was 0.31% (7,750/2,466,364) T1DM and 3.65% (89,990/2,466,364) T2DM. The EOMR algorithms also left more people unclassified 11,439 (12%), as to their type of diabetes compared with 2,380 (2.4%), for the new algorithm. Those people who were only classified by the EOMR system differed in terms of older age, and apparently better glycaemic control, despite not being prescribed medication for their diabetes (p < 0.005). Increasing the degree of problem orientation of the medical record system can improve the accuracy of recording of diagnoses and, therefore, the accuracy of using routinely collected data from CMRs to determine the prevalence of diabetes mellitus; data processing strategies should reflect the degree of problem orientation.

The role of temperament by family environment interactions in child maladjustment.

PubMed

Chen, Nan; Deater-Deckard, Kirby; Bell, Martha Ann

2014-11-01

In order to advance our understanding of the etiology of individual differences in child maladjustment (i.e., conduct and emotional problems), we tested hypotheses about the statistical interactions between child temperament and two aspects of the family environment: maternal negativity and positivity, and household chaos (e.g., crowding, noise, lack of routines). Mothers (n = 149) reported on their child's effortful control, negative affect, surgency, and behavioral/emotional problems. The age range of the children was 3 to 7 years old and half of the sample was girls. Observers rated maternal negativity and positivity based on brief structured interaction tasks in the laboratory. Child temperament moderated the association between maternal negativity/positivity and child maladjustment. Maternal negativity and child problem behavior were associated only for those children who also were high in surgency or negative affectivity. Maternal positivity was associated with less child problem behavior for those high in surgency. Child effortful control interacted with both maternal negativity and chaos. Maternal negativity and child problem behavior were most strongly associated for children who were low in effortful control and living in chaotic homes. The results point to distinct transactions between child temperament and maternal negativity/positivity that depend in part on the dimensions of temperament and parenting behavior in question.

The age range of the children was 3 to 7 years old and half of the sample was girls. Observers rated maternal negativity and positivity based on brief structured interaction tasks in the laboratory. Child temperament moderated the association between maternal negativity/positivity and child maladjustment. Maternal negativity and child problem behavior were associated only for those children who also were high in surgency or negative affectivity. Maternal positivity was associated with less child problem behavior for those high in surgency. Child effortful control interacted with both maternal negativity and chaos. Maternal negativity and child problem behavior were most strongly associated for children who were low in effortful control and living in chaotic homes. The results point to distinct transactions between child temperament and maternal negativity/positivity that depend in part on the dimensions of temperament and parenting behavior in question.

The usual two-dimensional (2D) barcode patterns do not encrypt secret information. However, secret information is sometimes needed to increase the security features of barcode patterns. Therefore, this paper proposes 2D barcode patterns created by two-beam writers to encrypt extra binary data for encoding secret information. The proposed 2D barcode patterns are composed of many grating dots and the fringes of the grating dots are classified into four types. The first type of fringe possesses a pitch of 1.1 μm and an orientation of -45°, the second type of fringe possesses a pitch of 1.2 μm and an orientation of -45°, the third type of fringe possesses a pitch of 1.1 μm and an orientation of 45°and the fourth type of fringe possesses a pitch of 1.2 μm and an orientation of 45°. All the fringes with a 1.1 μm pitch can show a color and all the fringes with a 1.2 μm pitch can show another color when a microscope is used to inspect them. Therefore, extra binary data for encoding secret information can be formed with the two pitches. On the other hand, all the fringes with a -45° orientation can become bright for a viewing direction and all the fringes with a 45° orientation can become bright for another viewing direction when one looks at them. Therefore, the grating dots with the -45° fringe orientation and the grating dots with the 45° fringe orientation can be used to show a positive barcode image and a negative barcode image, respectively. Both the positive and negative barcode images can be used to derive the barcode data. The experiment shows that the proposed barcode patterns can be used conveniently and correctly.

The aim was to investigate the influence of parents' negative mood state and parenting stress on behavior in children with newly diagnosed cancer. A total of 123 parents (n=58 fathers, n=65 mothers) of 67 children with newly diagnosed cancer completed three questionnaires separately at the same time measuring parents' negative mood state, parenting stress, and child behavior problems. Parents' negative mood state was weakly correlated to more child behavior problems (r=0.31, p<0.01), and higher levels of parenting stress were strongly correlated to more child behavior problems (r=0.61, p<0.01). Mediation analyses indicated that the relationship between parents' negative mood state and child behavior problems (c=0.29, p=0.02 (fathers); c=0.25, p=0.04 (mothers)) became non-significant after mediating for parenting stress (c'=0.003, p=0.98 (fathers); c'=0.10, p=0.42 (mothers)). The indirect effect of parents' negative mood state and child behavior problems was only significant for fathers (95% CI [0.12; 0.51]), indicating that parenting stress mediates the effect between fathers' negative mood state and child behavior problems. This is the first study to demonstrate the mediational role of parenting stress in fathers of a child with newly diagnosed cancer. Copyright © 2014 John Wiley & Sons, Ltd.

2008-09-01

Online discussion forums are often used by people with eating disorders. This study analyses 2,072 threads containing a total of 14,903 postings from an unmoderated German "prorecovery" forum for persons suffering from bulimia nervosa (www.ab-server.de) during the period from October 2004 to May 2006. The threads were inductively analyzed for underlying structural types, and the various types found were then analyzed for differences in temporal and quantitative parameters. Communication in the online discussion forum occurred in three types of thread: (1) problem-oriented threads (78.8% of threads), (2) communication-oriented threads (15.3% of threads), and (3) metacommunication threads (2.6% of threads). Metacommunication threads contained significantly more postings than problem-oriented and communication-oriented threads, and they were viewed significantly more often. Moreover, there are temporal differences between the structural types. Topics relating to active management of the disorder receive great attention in prorecovery forums.

The Object Oriented Modeling and Design seminar is intended for software professionals and students, it covers the concepts and a language-independent graphical notation that can be used to analyze problem requirements, and design a solution to the problem. The seminar discusses the three kinds of object-oriented models class, state, and interaction. The class model represents the static structure of a system, the state model describes the aspects of a system that change over time as well as control behavior and the interaction model describes how objects collaborate to achieve overall results. Existing knowledge of object oriented programming may benefit the learning of modeling and good design. Specific expectations are: Create a class model, Read, recognize, and describe a class model, Describe association and link, Show abstract classes used with multiple inheritance, Explain metadata, reification and constraints, Group classes into a package, Read, recognize, and describe a state model, Explain states and transitions, Read, recognize, and describe interaction model, Explain Use cases and use case relationships, Show concurrency in activity diagram, Object interactions in sequence diagram.

Communication in production animal medicine: modelling a complex interaction with the example of dairy herd health medicine

2011-01-01

Background The importance of communication skills in veterinary medicine is increasingly recognised. Appropriate communication skills towards the client are of utmost importance in both companion animal practice and production animal field and consultancy work. The need for building a relationship with the client, alongside developing a structure for the consultation is widely recognised and applies to both types of veterinary practice. Results Veterinary advisory practice in production animal medicine is, however, characterised by a more complex communication on different levels. While the person-orientated communication is a permanent process between veterinarian and client with a rather personal perspective and defines the roles of interaction, the problem-orientated communication deals with emerging difficulties; the objective is to solve an acute health problem. The solution - orientated communication is a form of communication in which both veterinarian and client address longstanding situations or problems with the objective to improve herd health and subsequently productivity performance. All three forms of communication overlap. Conclusions Based on this model, it appears useful for a veterinary practice to offer both a curative and an advisory service, but to keep these two separated when deemed appropriate. In veterinary education, the strategies and techniques necessary for solution orientated communication should be included in the teaching of communication skills. PMID:21777495

Direct and Indirect Associations Between Social Anxiety and Nicotine Dependence and Cessation Problems: Multiple Mediator Analyses

PubMed Central

2014-01-01

Introduction: Little empirical work has evaluated why socially anxious smokers are especially vulnerable to more severe nicotine dependence and cessation failure. Presumably, these smokers rely on cigarettes to help them manage their chronically elevated negative affect elicited by a wide array of social contexts. Methods: The current study examined the direct and indirect effects of social anxiety cross-sectionally in regard to a range of smoking processes among 466 treatment-seeking smokers. Negative affect and negative affect reduction motives were examined as mediators of the relations of social anxiety with nicotine dependence and cessation problems. Results: Social anxiety was directly and robustly associated with perceived barriers to smoking cessation and problems experienced during past quit attempts. Social anxiety was also associated with greater nicotine dependence and smoking inflexibility indirectly through negative affect and negative affect smoking motives. Negative affect and smoking to reduce negative affect mediated these relations. Conclusions: These findings document the important role of negative affect and negative affect reduction motives in the relationships of social anxiety with nicotine dependence and cessation problems.

Background Although drinking for tension reduction has long been posited as a risk factor for alcohol-related problems, studies investigating anxiety in relation to risk for alcohol problems have returned inconsistent results, leading researchers to search for potential moderators. Negative urgency (the tendency to become behaviorally dysregulated when experiencing negative affect) is a potential moderator of theoretical interest because it may increase risk for alcohol problems among those high in negative affect. The present study tested a cross-sectional mediated moderation hypothesis whereby an interactive effect of anxiety and negative urgency on alcohol problems is mediated through coping-related drinking motives. Method The study utilized baseline data from a hazardously drinking sample of young adults (N = 193) evaluated for participation in a randomized controlled trial of naltrexone and motivational interviewing for drinking reduction. Results The direct effect of anxiety on physiological dependence symptoms was moderated by negative urgency such that the positive association between anxiety and physiological dependence symptoms became stronger as negative urgency increased. Indirect effects of anxiety and negative urgency on alcohol problems (operating through coping motives) were also observed. Conclusions Although results of the current cross-sectional study require replication using longitudinal data, the findings suggest that the simultaneous presence of anxiety and negative urgency may be an important indicator of risk for AUDs via both direct interactive effects and indirect additive effects operating through coping motives. These findings have potentially important implications for prevention/intervention efforts for individuals who become disinhibited in the context of negative emotional states. PMID:26031346

Working conditions in call/contact centers influence employees' perceptions of their relations with the organization and their attitudes to work. Such perceptions can be analyzed through the psychological contract. The association between the relational/transactional orientation of the psychological contract and intention to quit the organization was examined, as well as the mediating role of affective commitment in employment relations. Data were collected from 973 employees in a cross-sectional survey. Analysis confirmed that there was a statistically significant relation between the orientation of the psychological contract and intention to quit, which was positive for transactionally oriented and negative for relationally oriented contracts. A mediating role for affective commitment was also confirmed, and a full mediating effect was reported for both orientations.

From the advances in computer vision methods for the detection, tracking and recognition of objects in video streams, new opportunities for video surveillance arise: In the future, automated video surveillance systems will be able to detect critical situations early enough to enable an operator to take preventive actions, instead of using video material merely for forensic investigations. However, problems such as limited computational resources, privacy regulations and a constant change in potential threads have to be addressed by a practical automated video surveillance system. In this paper, we show how these problems can be addressed using a task-oriented approach. The system architecture of the task-oriented video surveillance system NEST and an algorithm for the detection of abnormal behavior as part of the system are presented and illustrated for the surveillance of guests inside a video-monitored building.

[Regulation of Positive and Negative Emotions as Mediator between Maternal Emotion Socialization and Child Problem Behavior].

The present study investigated five to six year old children's ability to regulate negative and positive emotions in relation to psychosocial problem behavior (N=53). It was explored, whether mothers' supportive and nonsupportive strategies of emotion socialization influence children's problem behavior by shaping their emotion regulation ability. Mothers reported on children's emotion regulation and internalizing and externalizing problem behavior via questionnaire, and were interviewed about their preferences for socialization strategies in response to children's expression of negative affect. Results showed that children with more adaptive expression of adequate positive emotions had less internalizing behavior problems. When children showed more control of inadequate negative emotions, children were less internalizing as well as externalizing in their behavior. Furthermore, results indicated indirect relations of mothers' socialization strategies with children's problem behavior. Control of inadequate negative emotions mediated the link between non-supportive strategies on externalizing problem behavior. Results suggest that emotion regulatory processes should be part of interventions to reduce the development of problematic behavior in young children. Parents should be trained in dealing with children's emotions in a constructive way.

A negative birefringent film, useful in liquid crystal displays, and a method for controlling the negative birefringence of a polyimide film is disclosed which allows the matching of an application to a targeted amount of birefringence by controlling the degree of in-plane orientation of the polyimide by the selection of functional groups within both the diamine and dianhydride segments of the polyimide which affect the polyimide backbone chain rigidity, linearity, and symmetry. The higher the rigidity, linearity and symmetry of the polyimide backbone, the larger the value of the negative birefringence of the polyimide film.

The emotional states of pregnant women affect the course of their pregnancies, their deliveries and the behaviour and development of their infants. The aim of this study is to analyse the influence of positive and negative maternal emotional states on neonatal behaviour at 2-3 days after birth. A sample of 163 healthy full-term newborns was evaluated using the Neonatal Behavioral Assessment Scale. Maternal anxiety, perceived stress, and emotional stability during pregnancy were evaluated in the immediate postpartum period with the State Trait Anxiety Inventory and the Perceived Stress Scale. Moderate levels of anxiety during pregnancy alter infant orientation and self-regulation. These aspects of infant behaviour could lead to later attachment, behavioural and developmental problems. Maternal emotional stability during pregnancy improves infant self-regulation and several aspects of infant behaviour that may predispose them to better interactions with their parents.

2015-01-01

Youths’ risk for adjustment problems in contexts of political violence is well-documented. However, outcomes vary widely, with many children functioning well. Accordingly, moving beyond further documenting the risk for many negative outcomes associated with living in contexts of political violence, a second generation of research is moving towards identifying the mechanisms and conditions that contribute to children’s adjustment. Increasing support is emerging for understanding effects on children in terms of changes in the social contexts in which children live, and in the psychological processes engaged by these social ecologies. Selected themes are considered, including (a) the need to study multiple levels of the social ecology, (b) differentiating between the effects of exposure to contexts of political versus non-political violence, and (c) theories about explanatory processes. Selected research pertinent to these directions is reviewed, including findings from a six-wave longitudinal study on political violence and children in Northern Ireland. PMID:26877765

Higher education is moving with deliberate speed to an electronic classroom. Much has been published on faculty experiences with World Wide Web (WWW) course delivery. However, little research exists on the evaluation of these methods. The purpose of this study was to evaluate students' perceptions of two approaches to teaching: classroom and WWW modules. Classroom methods were rated significantly higher in relation to content, interaction, participation, faculty preparation, and communication. Technical skills were rated higher for WWW modules. Critical thinking and time allotted for assignments were not significantly different between classroom and WWW instruction. Open-ended comments were rich and supported both positive and negative aspects of classroom and WWW-based modules. Implications call for creativity in course development, course redesign and orientation, active communication with students, support for technical problems, faculty development, and university-wide planning through partnerships.

Aluminum nitride (AlN) coating is a potential candidate for addressing the problems of MHD pressure drop, tritium permeation and liquid metal corrosion of the test blanket module of fusion reactor. In this work, AlN coatings were grown on stainless steel by magnetron sputtering. Grazing incidence X-ray diffraction measurement revealed that formation of mixed phase (wurtzite and rock salt) AlN was favored at low discharge power and substrate negative biasing. However, at sufficiently high discharge power and substrate bias, (100) oriented wurtzite AlN was obtained. Secondary ion mass spectroscopy showed presence of oxygen in the coatings. The highest value of hardness and Young's modulus were 14.1 GPa and 215 GPa, respectively. Scratch test showed adhesive failure at a load of about 20 N. Wear test showed improved wear resistance of the coatings obtained at higher substrate bias.

Demirhan, Eda; Randler, Christoph; Horzum, Mehmet Barış

2016-01-01

In this study, the relationships among problematic mobile phone use, age, gender, personality and chronotype of Turkish university students were examined. The study included 902 university students (73% female, 27% male) and their participation in the study was anonymous and voluntary. Data were collected from each participant by assessing a demographic questionnaire, Composite Scale of Morningness (CSM) as a measure of chronotype, the Big Five Inventory (BIG-5) for personality assessment and Mobile Phone Problem Usage Scale (MPPUS). The most important result was that CSM scores were the best predictor for problematic mobile phone usage, and as a consequence, evening-oriented university students scored higher on the MPPUS. This result remained, even when compared with the most influential personality predictor, conscientiousness. In addition, while extraversion positively predicted, emotional stable and chronotype negatively predicted problematic mobile phone use. Lastly, age and gender were not predictors of problematic mobile phone use.

There have been only few attempts to explore the relationship between emotional intelligence (EI) and religiosity. However, none of them included measures of ability EI. In two studies, we investigated the potential associations between various aspects of religious belief and ability and trait EI. In Study 1 (N = 240), we found that ability EI was positively associated with general level of religious belief. Study 2, conducted among Polish Christians (N = 159), replicated the previous result on the connection between ability EI and religion. Moreover, both trait and ability EI were negatively correlated with extrinsic religious orientation and negative religious coping. Additional analysis showed that extrinsic orientation mediated the relationship between ability EI and religiosity.

Interrupted object-based updating of reach program leads to a negative compatibility effect.

PubMed

Vainio, Lari

2009-07-01

The author investigated how the motor program elicited by an object's orientation is updated by object-based information while a participant reaches for the object. Participants selected the hand of response according to the thickness of the graspable object and then reached toward the location in which the object appeared. Reach initiation times decreased when the handle of the object was oriented toward the responding hand. This positive compatibility effect turned into a negative compatibility effect (NCE) during reach execution when the object was removed from the display 300 ms after object onset or replaced with a mask at movement onset. The results demonstrate that interrupted object-based updating of an ongoing reach movement triggers the NCE.

Elasticity of smectic liquid crystals with in-plane orientational order and dispiration asymmetry

The Nelson-Peliti formulation of the elasticity theory of isolated fluid membranes with orientational order emphasizes the interplay between geometry, topology, and thermal fluctuations. Fluid layers of lamellar liquid crystals such as smectic-C , hexatic smectics, and smectic-C* are endowed with in-plane orientational order. We extend the Nelson-Peliti formulation so as to bring these smectics within its ambit. Using the elasticity theory of smectics-C*, we show that positive and negative dispirations (topological defects in Smectic-C* liquid crystals) with strengths of equal magnitude have disparate energies—a result that is amenable to experimental tests.

Objective The aim of this study is to investigate psychological barriers (illness perceptions, insulin beliefs, and coping strategies) to optimal insulin therapy among adolescents with type 1 diabetes (T1D), with a specific focus on gender differences and mode of treatment (insulin pump vs pen). Methods A total of 105 males and females (12–20 years) participated in this study. The Brief Illness Perception Questionnaire, the Beliefs about Medicines Questionnaire, and the Adolescent Coping Orientation for Problem Experiences were completed. Additionally, diabetes clinical data were collected by the Norwegian Childhood Diabetes Registry. Results Females had significantly more negative illness perceptions than males on all dimensions (p<0.05), with moderate-to-large effect sizes. Regarding insulin beliefs, females scored significantly higher than males on insulin concern (p<0.001), indicating more concerns about insulin. There were no significant gender differences on perceptions of insulin necessity. Finally, females scored significantly higher on the coping strategies being social and solving family problems (p<0.01), indicating more positive coping among females than males for these subscales. In terms of treatment mode, the only statistically significant difference in the psychological aspects was for the illness perception treatment control, with patients using insulin pen reporting more negative perceptions on this dimension than patients using insulin pump. Conclusions Addressing psychological aspects may be a clinically important supplement to standard somatic T1D care. The consistent finding of gender differences across the psychological measures implies that a tailored treatment approach for males and females with T1D may be warranted. PMID:27403325
