先前知识对初中学生学习家族相似性类别的影响研究

采用特征—主题的类别学习范式,考察了先前知识对初中学生学习具有家族相似性结构人工类别的影响。结果表明:基于先前知识的主题关系对初中学生的类别学习有显著促进;初中学生在基于已有知识的类别学习中更多地获得了知识关联特征的信息,同时也能对机械特征保持敏感。     

幼儿心理压力的现状及与行为问题、家庭生态环境之间的关系

本文考察了幼儿心理压力的现状,并对性别、年龄和入托性质等影响因素做了检验与分析,此外还进行了幼儿心理压力与行为问题及家庭生态环境之间的相关研究。结果发现,68.9%幼儿存在一定程度的心理压力,其中压力较大的孩子约占10%;幼儿的心理压力与性别无关,但与年龄、入托性质等因素有关,大班比小班、全托比日托的孩子的心理压力大;幼儿心理压力与行为问题尤其是违纪行为存在一定的关系,与家庭生态环境的诸因素之间也都存在一定的关系。     

Supportive Social Contexts and Intentions for Civic and Political Participation: An Application of the Theory of Planned Behaviour

We investigated how general social support from family, friends and acquaintances, and community predicted intentions for civic (e.g. volunteering) and political (e.g. petitioning) participation via the constructs specified in the theory of planned behaviour. Participants were young adults living in the former East Germany, a post‐communist region, who were surveyed by telephone in 2010 (N_civic = 695, N_political = 694). Civic participation was perceived more favourably than political participation. Supportive family predicted intentions for civic participation; supportive community services predicted both types of intentions; and supportive friends and acquaintances had no significant effects. The mediating variables were subjective norms and perceived behavioural control, but not attitudes. All effects were controlled for sociodemographic variables, richness of the social network, and past experience of civic and political participation. Findings underscore the role of supportive community in fostering both civic and political participation. Copyright © 2014 John Wiley & Sons, Ltd.     

Associations between work family conflict,emotional exhaustion,musculoskeletal pain,and gastrointestinal problems in a sample of business travelers

The aim of the study was to examine the associations among work‐family conflict (WFC), emotional exhaustion, musculoskeletal (MS) pain, and gastrointestinal problems on a sample of business travelers (n = 2,093). An additional aim was to examine differences in the mentioned relationships among three traveler groups: commuters, national travelers, and international travelers. The study was conducted in a large Norwegian oil and gas company, and the company's business travel database was utilized to examine business travel. Structural equation modeling (SEM) revealed significant relations between WFC and emotional exhaustion and between emotional exhaustion and health problems. Contrary to the expectations, no direct association was found between WFC and health problems. However, we found that emotional exhaustion mediated the relation between WFC and health outcomes. The results from multi‐group analysis revealed that associations among WFC, emotional exhaustion, and health‐outcomes showed a similar pattern for commuters, national travelers, and international travelers. However, the association between emotional exhaustion and MS pain proved to be significantly stronger for the commuter group compared to the national and international travel groups. Practical implications and the consequences of these findings for future research are discussed.     

The combined influence of hardiness and cohesion on mental health in a military peacekeeping mission: A prospective study

A large number of studies have shown that hardiness and cohesion are associated with mental health in a military context. However, most of them are presented without controlling for baseline mental health symptoms, which is their most significant source of error. The present study investigates the combined effect of hardiness and cohesion in a prospective design, controlling for baseline levels of symptoms among Norwegian personnel serving in a peacekeeping operation in Kosovo. Multivariate regression analyses were performed in which self‐reported mental health complaints were regressed on our explanatory variables. Our findings suggest that both cohesion and hardiness contributed to increased stress resiliency, as measured by a lower level of reported mental health complaints. Our baseline measure of mental health accounted for a larger proportion of the variance than our other predictors. A significant interaction between cohesion and hardiness suggested a combined effect, over and above the individual contributions of the predictors. For individuals who scored high on hardiness, cohesion levels did not influence levels of mental health complaints. Individuals who scored low on hardiness, on the other hand, reported lower levels of mental health complaints when cohesion levels were high.
