Understanding the Relationships Among HIV/AIDS-Related Stigma,Health Service Utilization,and HIV Prevalence and Incidence in Sub-Saharan Africa: A Multi-level Theoretical Perspective

HIV-positive individuals often face community-wide discrimination or public shame and humiliation as a result of their HIV-status. In Sub-Saharan Africa, high HIV incidence coupled with unique cultural contexts make HIV-positive individuals particularly likely to experience this kind of HIV/AIDS-related (HAR) stigma. To date, there is a relatively small amount of high-quality empirical literature specific to HAR stigma in this context, supporting the notion that a better understanding of this phenomenon is needed to inform potential interventions. This paper provides a thorough review of the literature specific to HAR stigma in Sub-Saharan Africa, finding (a) qualitative support for the existence of important relationships between HAR stigma and health service utilization and barriers; (b) a need for more quantitative study of stigma and its relationships both to health service utilization and to HIV outcomes directly; and (c) a disconnect between methodological techniques used in this context-specific literature and well-known theories about stigma as a general phenomenon. This paper then draws from its empirical literature review, as well as from well-known theoretical frameworks from multiple disciplines, to propose a theoretical framework for the ecological and multilevel relationships among HAR stigma, health service utilization, and HIV outcomes in this context.     

The homogeneity effect on figure/ground perception in infancy

We examined whether the homogeneity of the two profiles of Rubin's goblet affects figure/ground perception in infants. We modified the two profiles of Rubin's goblet in order to compare figure/ground perception under four test patterns: (1) two profiles painted with horizontal lines (horizontal-line condition), (2) two profiles painted middle gray (uni-color condition), (3) one profile painted light gray and the other dark gray (two-color condition), and (4) a goblet painted with concentric circles (concentric-circles condition). In the horizontal-line condition the homogeneity of the profile was strengthened, and in the two-color condition the homogeneity of the profile was weakened compared to the uni-color condition, which was an original Rubin's goblet. In the concentric-circles condition the homogeneity of the reversed areas of the horizontal-line were strengthened.     

Fireman's job stress: Integrating work/non-work conflict with Job Demand-Control-Support model

IntroductionHeavy working load and uncontrollable schedule often lead firemen to face to conflict between work and non-work life.ObjectiveThis study aims to examine the mediating role of work/non-work conflict between firemen's job stress and job demand, job control, job support and family support.MethodQuestionnaire survey was used for data collection. Four hundred and twenty-two firemen returned completed questionnaires. Structure equation modelling was employed for data analysis.ResultsWork/leisure conflict (WLC) and work/family conflict (WFC) mediate partially the relationship between job demand and job control, job support and job stress. The relationship between family support and job stress is fully mediated by WLC and WFC.ConclusionWFC and WLC are integrated into Job Demand-Control-Support model model in current research to narrow the gap of job stress theory.     

Analyse Préliminaire des Qualités Psychométriques d’une Version Française du Work Design Questionnaire

The Work Design Questionnaire (Morgeson & Humphrey, 2006) assesses numerous work characteristics. The present research was designed to assess the psychometric properties of a French version of this tool (i.e., WDQ-F) through the following analyses: confirmatory factor analysis, reliability, and nomological validity with work satisfaction, engagement and burnout. In Studies 1 and 2, results of confirmatory factor analyses showed that the fit indices for the 21-dimension model were poor and that seven items displayed low factor loadings. In Study 2, results showed that a reduced version of the WDQ-F (71 items) demonstrated better psychometric properties than the 77-item version of the questionnaire. In addition, correlation analyses provided support for the nomological validity of the WDQ-F.     

La qualité de la relation leader/membre et les comportements innovants : le rôle modérateur de la résistance au changement

Researchers have proposed that high quality of supervisor–employee relationships (Basu & Green, 1997; Scott & Bruce, 1994; Sanders, Moorkamp, Torka, Groeneveld & Groeneveld, 2010) fosters innovative behaviour. Moreover, researchers have acknowledged that this relationship is not clear (Rosing, Frese & Bausch, 2011; Volmer, Spurk & Niessen, 2012). The present study aims at testing the moderating role of resistance to change in the LMX-innovative behaviour relationship. Results of a study based on 160 participants from an organization provide empirical support to this hypothesis.     

Validity of the trait emotional intelligence questionnaire in sports and its links with performance satisfaction

ObjectiveThis research project consisted of two studies aimed at validating the trait emotional intelligence questionnaire (TEIQue) in a sports sample.DesignStudy 1 used a confirmatory factor analysis (CFA) to investigate if the original 4-factor structure of the TEIQue could be replicated in a sample of athletes. In addition, we explored the relationship between trait emotional intelligence (trait EI) and the demographic variables age, sex, type of sport (individual vs. team), expertise, and years of training. Study 2 used a path analysis approach to explore if trait EI is related to performance satisfaction through stress appraisal and coping behaviors.MethodIn Study 1, 973 athletes completed the TEIQue and a demographic questionnaire. In Study 2, 291 athletes completed the TEIQue. Moreover, with a recent competition in mind, they completed the Coping Inventory for Competitive Sports, as well as items on perceived intensity of stress, perceived controllability of stress, challenge and threat appraisals, coping effectiveness, and performance satisfaction.ResultsStudy 1 showed with a CFA that the original 4-factor structure of the TEIQue could be replicated in a sports sample. Of the demographic variables, only age showed a significant positive relationship with trait EI. Study 2 showed that trait EI was related to performance satisfaction through stress appraisal and coping variables.ConclusionsThis research showed that the TEIQue can be used with athletes and that trait EI is useful for understanding certain aspects of sports performance satisfaction.     

Measuring Epistemic Curiosity in Young Children

Epistemic curiosity (EC) is the desire to obtain new knowledge capable of either producing positive experiences of intellectual interest (I‐type) or of reducing undesirable conditions of informational deprivation (D‐type). Although researchers acknowledge that there are individual differences in young children's epistemic curiosity, there are no existing measures to assess the I‐ and D‐type constructs of EC in early childhood. The aim of this study was to develop and validate parent‐report scales that reliably assessed early expressions of I‐ and D‐ type EC in young children. To develop the I/D‐Young Children (I/D‐YC) scales, 16 potential items were administered to 316 parents of children aged 3 to 8. These items were adaptations of an existing adult self‐report measure of EC as well as newly developed items. Confirmatory factor analyses demonstrated that a 10‐item 2‐factor (5 I‐type, 5 D‐type) model had the best fit. Construct validity analyses and psychometric data indicated that our newly developed I/D‐YC scales are valid and reliable measures of individual differences in early expressions of I‐ and D‐type EC.

公益组织课外辅导对流动儿童领悟社会支持的影响

通过对选自北京市打工子弟小学的159名流动儿童进行问卷调查,探讨公益组织的社会干预对流动儿童领悟社会支持能力及情绪情感的影响。结果表明:(1)在公益组织实施课外团体辅导后,干预组流动儿童领悟社会支持得分与积极情感得分均显著高于对照组流动儿童。(2)在消极情感得分上,干预组与对照组不存在显著差异。(3)领悟社会支持与积极情感存在显著正相关,与消极情感存在负相关。这表明,通过公益组织实施课外辅导方式进行的社会干预能够有效提高流动儿童的领悟社会支持水平。     

风险投资中的短视效应及理论解释

“投资者难以长远地将多重投资看作整体,而更倾向于分割成单一决策进而表现出每次决策风险规避的现象”被称为风险投资中的短视效应.短视/远视风险投资常通过单一决策/重复决策范式予以研究.大多数的研究发现,在单一决策条件下,投资者接受投资的人数比例或者投资金额低于重复决策条件.短视效应的调节机制有反馈频率、投资灵活性、选择组块、风险状况等.研究者分别提出短视损失厌恶（myopic loss aversion,简称MLA）理论和短视预期理论（myopic prospect theory,MPT）对短视现象进行解释;但这些理论受到基于齐当别理论（equate-to-differentiate theory）研究的挑战.文章在总结短视效应已有相关研究的基础上指出今后有必要深入探索的方向.
