Psychological availability and work engagement: The moderating role of sex and race

This study sought to determine the relationship of sex and race as moderators of psychological availability on work engagement in various South African organisations. Participants were 1 059 employees predominantly from the corporate sector in Gauteng province (females = 61%, blacks = 36%). Cross-sectional survey data were collected from the employees using the Psychological Conditions Scale and the Utrecht Work Engagement Scale (UWES). Moderated hierarchical regression analyses tested the prediction of work engagement from psychological availability, while controlling for the sex and race of employees. Psychological availability increased the level of work engagement for both men and women, the relationship, however, was stronger for women as compared to men. White employees were less work engaged compared to other race group members. Psychological availability was higher for the black, Indian, and coloured employees compared to white employees. The results confirmed the positive relationship of psychological availability on work engagement, and that sex and race differences exist for employees in a developing country.     

Body mass index,peer victimization,and body dissatisfaction across 7 years of childhood and adolescence: Evidence of moderated and mediated pathways

Numerous studies have reported that children and adolescents who are overweight are more likely to get bullied, yet the literature is replete with methodological limitations. We examined the transactional associations between peer victimization and body mass index (BMI), considering potential mediating (body dissatisfaction) and moderating (biological sex) factors. Participants (n = 631) came from the McMaster Teen Study, where students were assessed annually between Grades 5–11, approximately half were girls (53.9%), and the majority were white (76.4%). Peer victimization (from Grade 5) and body dissatisfaction (from Grade 6) were self‐reported by students, while parents reported their child's height and weight (from Grade 5). Cascade models were built up sequentially using path analysis across 2‐year increments (Grades 5, 7, 9, and 11). The final model had excellent fit to the data (χ² = 73.961, df = 66, p = 0.234). Grade 5 peer victimization had a direct effect on BMI across a 2‐year period in girls (b = 0.59, SE = 0.21, p = 0.005) and boys (b = 0.82, SE = 0.30, p = 0.006), and an indirect effect on BMI via body dissatisfaction across a 4‐year period (b = 0.074, 95% CI = 0.012–0.152, p = 0.036). At no point did BMI directly increase risk for peer victimization, yet there were indirect effects via body dissatisfaction among girls but not boys. Peer victimization and body dissatisfaction were proximally and longitudinally related at every time point and there was a transactional association in late‐adolescence among girls but not boys. Targeting modifiable factors in the social (peer victimization) and psychological (body dissatisfaction) domains may limit accelerated weight gain and the health risks associated with excess adiposity.     

Understanding the past: Investigating the role of availability,outcome, and hindsight bias and close calls in visual pilots' weather‐related decision making

Past events, such as “close calls,” can provide valuable learning opportunities, especially in aviation, where learning from past errors could potentially help to avoid future incidents or accidents. This study investigated whether three cognitive biases (availability, outcome, and hindsight bias) could influence pilots' perceptions of past events, which in turn might influence their perception of events yet to occur. Study 1 found that pilots were influenced by the outcome of a flight when judging decision quality. Of particular interest was that pilots interpreted events that led to a close call very similarly to those that had positive outcomes, which may reinforce risky behaviour. However, although adequately powered, Study 1 found no evidence of availability bias: Exposure to one of four outcomes did not appear to influence later decisions. Study 2 found that having read a flight report, particularly if it ended in a crash, pilots consistently overestimated their likelihood of predicting the actual outcome, which may reduce any opportunity to learn. These findings suggest that two of the three cognitive biases explored in this study could influence a pilot's perception of past events in ways that may adversely affect how they make future decisions that in turn may affect flight safety.     

World View Concepts in Existential Family Therapy

Essence oriented and existence oriented approaches to family psychotherapy are very different treatment forms. This article compares and contrasts these two orientations in an effort to clarify the basic world view beliefs in existential psychotherapy with couples and families.     

“易得性启发式”与决策框架对风险决策倾向的影响

研究目的:探讨易得性启发式对风险决策认知过程的影响,以及易得性启发式与决策框架相互作用下的风险投资行为特点。方法:采用2×2×7混合实验设计和情境实验。结果:成功结果的易得性启发式导致对风险决策问题采用自上而下加工,失败结果为自下而上加工;成功结果时投资倾向为风险趋向,失败结果为风险规避;易得性启发式与决策框架共同影响风险投资倾向。结论:易得性启发式影响风险决策的认知加工过程,并与决策框架对风险投资倾向产生交互作用。     

Marcel's Testimony in Existential Psychotherapy with Couples and Families

In recent years a number of family therapists and teachers of family therapy have questioned the direction of the family therapy movement into relationship-distant and procedurally based treatment orientations. The purpose of this article is to outline Gabriel Marcel's concept of testimony and to show how this concept can be utilized to facilitate an increased emphasis upon the treatment relationship during marital and family psychotherapy.     

The effect of signaled reinforcement availability on concurrent performances in humans

During Phase I, three female human subjects pressed a button for monetary reinforcement in two-component concurrent variable-interval schedules. Five different reinforcement frequencies were used in component A, whereas the reinforcement frequency in component B was held constant. Absolute rates of responding conformed to equations proposed by Herrnstein to describe concurent performances, and the ratios of the response rates and the times spent in the two components conformed to the matching law. During Phase II, the availability of reinforcement in component A was signaled by the illumination of a lamp. This resulted in suppression of response rates in component A and elevation of response rates in component B, these changes being reflected in a distortion of the matching relationship which took the form of a bias in favor of component B.     

影响汉语动词、名词识别因素的回归分析

采用回归分析的方法,考察了6个因素对汉语动词、名词识别的影响。结果表明,各变量间有一定的相关,也有相对的独立性。词频、获得年龄和义符熟悉性对词汇识别有显著影响。情境获得性与具体性相关显著,当回归模型中包含情境获得性时,具体性的作用减弱。获得年龄与义符熟悉性在名词回归方程中的解释量大于在动词中的。汉语动词和名词的回归模式既与拼音文字有明显差异,也有一定的共性。这是由汉字的特殊性和语言的共性共同决定的。     

Alcohol Availability and Violence among Inner-City Adolescents: A Multi-Level Analysis of the Role of Alcohol Outlet Density

Researchers recognize that the connection between alcohol and peer violence may relate to community level ecological factors, such as the location of businesses that sell alcohol. Building on previous research among adults, this study examines the relationship between alcohol outlet density and violent behaviors among adolescents, taking into account demographic characteristics, individual alcohol use, and neighborhood level socioeconomic indicators. Data drawn from a diverse Emergency Department based sample of 1,050 urban adolescents, combined with tract level data from the state liquor control commission and U.S. Census, were analyzed. Results of multivariate multi-level regression analysis indicate that alcohol outlet density is significantly related to adolescents’ violent behaviors, controlling for demographic characteristics and individual alcohol use. Census tract level socioeconomic indicators were not significantly associated with youth violence. Findings suggest that alcohol outlet density regulation should be considered as part of broader violence prevention strategies for urban adolescents.
