社会主义的历史沉思与“三个代表”的时代觉醒

对21世纪社会主义前途和命运的关注,最重要的是对社会主义的沉思。只有通过不断的沉思和反省,才会在新的历史条件下探索社会主义的一系列重大问题,从而得出具有划时代的社会主义新思想,使社会主义具有更强的生命力。“三个代表”思想是在21世纪的背景下社会主义历史沉思的科学结晶,是站在更高更广阔的视野下对社会主义命运和前途的把握。“三个代表”思想意蕴的社会主义价值是非常深远的,它不仅意蕴着中国社会主义的兴旺,而且昭示着世界社会主义的复兴。

The relationship between exposure to family violence in childhood and post-traumatic stress symptoms in young adulthood: The mediating role of social support

BackgroundExtensive research has examined the relationship between exposure to family violence and its long-term mental health effects. Social support has been found to moderate this relationship, but there is a dearth of research on its mediating role.ObjectivesThe article presents the results of a study on the relationship between witnessing interparental violence and experiencing parental violence during childhood and adolescence on the one hand, and post-traumatic stress symptoms (PTSS) during young adulthood on the other. In addition, the article presents results on the role of social support as a mediator in this relationship.Method, participants, and settingA cross-sectional survey was conducted among 516 Israeli university and college students (90.7% female, and 9.3% male; M age = 24.9, SD = 2.7) using a retrospective, self-administered questionnaire.ResultsThe results revealed that exposure to each pattern of family violence (i.e., witnessing interparental violence and experiencing parental violence) predicted higher levels of PTSS. Furthermore, social support was found to partially mediate the relationship between exposure to family violence during childhood and adolescence and current PTSS as well as its four symptoms, i.e., depression, sleep disturbance, dissociation, and anxiety.ConclusionsThe results of the current study highlight the important role of social support in the association between adversities experienced early in life and young adulthood outcomes. The findings are interpreted on the basis of Conservation of Resources Theory (Hobfoll et al., 1990), which served as the conceptual framework for the study. The limitations of the study and implications for future research are discussed.

Is academic tracking related to gains in learning competence? Using propensity score matching and differential item change functioning analysis for better understanding of tracking implications

This study analyzes gains in cognitive components of learning competence with respect to cohorts based on ability tracking in a Czech longitudinal study. Propensity score matching is used to form parallelized samples of academic and non-academic track students and to eliminate the effect of selective school intake. We applied regression models on the total scores to test for the overall track effect. Furthermore, we analyze scores and gains on the subscores and check for differential item functioning in Grade 6 and in change to Grade 9. While after 3 years, no significant difference between the two tracks was apparent in the total learning competence score, we did, however, find significant differences in some subscores and in the functioning of some items. We argue that item-level analysis is important for deeper understanding of the tracking implications and may provide the basis for more precise evidence-based decisions regarding the tracking policy.     

Teamwork and Entrepreneurial Behavior among K-12 Teachers in the United States

Abstract

This study attempted to identify the predictors of entrepreneurial behavior by assessing a series of variables that included teamwork skills and demographic variables, and to explore teachers’ experiences with teamwork. A sample of 367?K-12 public school teachers completed the survey. The findings indicated that teamwork predicts entrepreneurial behavior. Most participants received teamwork training through their school districts. Barriers to teamwork included time constraints, individual differences, and inability to collaborate.     

When screens replace backyards: strategies to connect digital-media-oriented young people to nature

Abstract

Children’s connection to nature (CTN) is declining with each generation, a concerning trend given that CTN is positively linked to wellbeing and environmentalism. A primary cause of this decline is that twenty-first-century youth engage with screens for several hours each day, which to a large extent replaces nature-based play. Researchers have proposed that this change represents a transition in human orientation, particularly in Westernized societies, from nature (biophilia) to digital media (videophilia). Interventions promoting nature-based play must acknowledge digital-media use as a competing leisure pursuit, but the literature presents little guidance for designing programs that will attract young people who are more oriented toward digital media than nature. Drawing on a wide breadth of research, we address this gap through (1) exploring the implications of videophilia for nature-based programming and (2) summarizing recommendations from a narrative literature review for designing interventions that appeal to digital-media-oriented youth.
