从河渭不足、夸父二死、弃其杖,化为邓林三个方面分析夸父逐日,得出夸父逐日的历史学解释:夸父逐日不是追赶太阳的逐走运动,也不是驱赶太阳的巫师祈雨活动,而是夸父族由于干旱和战争而进行的迁徙。最后,分析长期以来夸父逐日被曲解的原因。     

The Social Production of Bullying: Expanding the Repertoire of Approaches to Group Dynamics

Bullying research has widely included group dynamics as contextual factors. However, explanations addressing the causes of bullying predominantly emphasise individual dysfunctions related to aggression and empathy. Analysing qualitative data from Norwegian schools, this article explores four different group dynamics that may produce bullying behaviours as well as deactivate empathy. Drawing on theories of social hierarchies and ingroups/outgroups, the article offers new approaches to understanding the ways in which the intense markings of social distinctions between positions and cliques in peer culture represent significant social driving forces in school bullying.

‘He enjoyed it more than I did’!: young British Sikh women negotiating safe sex in heterosexual encounters

ABSTRACT

Sex education and relationship strategy of the U.K. allows parents to withdraw their children from sex education, which has left many young people especially those from Black Minority and Ethnic communities with low or no sex education. Similarly, the government's policy environment enables faith schools to teach these subjects under the tenets of their faith. This empirical research was carried out in South-West London using 12 qualitative interviews with women and men (ages 18–20 years) discusses young women's experiences of their first sexual encounter who navigate their reputations, relationships as well as negotiate safe sex in the absence of appropriate relationships and sex education. Sex education not only brings into focus sensitivities around gender but also tensions around religion in the U.K. Evidence from the study suggests that despite the importance placed by the Indian community on maintaining virginity, young women asserted that religion and culture did not prohibit them from exploring their sexuality. In this study, the priority is to present young women's voices and experience of sexual encounters.     

L'Organisation internationale du Travail et le travail pénitentiaire: une invitation à changer de paradigme

Les auteurs reviennent sur la vision normative de l'OIT concernant le travail pénitentiaire, qu'ils jugent déconnectée de la réalité des prisons, où l'on constate un foisonnement de formes hybrides de travail des détenus, mêlant secteur public et secteur privé. Ils décrivent les controverses qui entourent la position de l'OIT, à l'heure où les États Membres pressent l'Organisation d'assouplir une vision dichotomique, toujours plus contestée. L'article montre les risques auxquels l'OIT s'expose si elle devait camper sur ses positions, mais aussi si elle adoptait la position défendue par certains de ses États Membres. Les auteurs proposent deux options permettant de dépasser ces positions antagonistes.     

On Reinventing OBM

Abstract

This article comments on an argument in favor of a change in OBM's content and focus to include certain empirical findings and theoretical constructs derived from fields like Cognitive and Social Psychology. Specifically, the argument suggests that personal beliefs such as optimism, self-efficacy, and response-efficacy are influential determinants of behavior that give rise to achievement motivation and a success-seeking typology. By incorporating such constructs into OBM, it is suggested that the field will better align itself with related disciplines sharing the goal of promoting personal success, thereby enhancing its performance-improvement toolkit and fostering greater recognition and acceptance for itself within mainstream Psychology. After summarizing key aspects of this argument, this paper identifies certain of its associated challenges and then presents some specific strategies by which the OBM community can chart a future course for the field.     

Network Composition,Social Integration,and Sense of Coherence in Chinese American Young Adults

Summary

This investigation examined the network composition, social integration, and sense of coherence in a group of 353 Chinese American students at a public university. About half (55.5%) of the sample had a Chinese-only (ethnically same) network while the remainder had either ethnically and/or racially mixed networks. Late immigrants (arriving after age 12) were more likely to have close relationships with other Chinese only, and American-borns and early immigrants (arriving before or at age 12) were more likely to have non-Chinese Asian and non-Asian members in their network. Greater racial/ ethnic similarity among network members was associated with greater network integration. Individuals with a racially/ethnically mixed network enjoyed the highest sense of coherence, followed by those with an ethnically same network, and those with either a racially-same or mixed network reported the lowest sense of coherence. Altogether, the findings suggest ethnically/racially similar networks afford a sense of comfort, but more diverse networks offer the reward of increased competence and better person-environment fit.     

Guiding the Acquisition of Therapist Ally Identity

Abstract

This paper suggests the appropriateness of adopting an ally identity for therapists who work with gay, lesbian, bisexual, and transgender (GLBT) stepfamilies. Using results from in-depth interviews, we demonstrate how research can assist those who wish to acquire knowledge regarding this marginalized group. Such scholarship can be helpful when therapists are acting as allies within therapeutic encounters, in interactions with colleagues, and in public discourse.     

More than Surface Tension: Femmes in Families

SUMMARY

This article raises questions about the lack of scholarly focus on butch/femme couples and their absence in studies of lesbian couples and family-building. In an era of lesbian marriage and lesbian parenting, femme and butch coupling and family-building remain unspoken topics within family studies, including lesbian, gay, bisexual, transgender (LGBT)–specific research. Moving beyond a focus on eroticism within the femme/butch couple, questions about how gender expression impacts other relationships dynamics, including the maintenance of long-term relationships, power and intimacy, domestic chores and child-rearing, are raised. The femme role in “homemaking,” that is, building and maintaining families, especially needs further exploration.
