The excessive and public consumption of alcohol with other men has been a traditional indication of manliness in Western cultures for many years. However, over the last two decades, this association has been eroded, in part through increased consumption by women. Within the gender‐relational context of this increase, we empirically explore ways in which particular (friendship) groups of young men and women (re)construct masculine identities. The male participants demonstrated greater discursive flexibility in enacting their gender identities through alcohol consumption compared with earlier NZ research although also greater constraints on change compared with more recent UK research. A minority of men constructed themselves as atypical in that they did not like rugby, beer or consuming vast quantities of alcohol. These men were all in professional occupations, and we speculate that their social class and financial status may enable them to negotiate alternative demonstrations of masculinity. We conclude that these findings could be explicated through an examination of national gendered identities that arose out of a pioneer culture, and the commodification of gender identities through alcohol consumption.

We investigated the influence of the child’s behavior on the quality of the mutual parent–child attachment relationships across three generations. We did so using a prospective longitudinal study which spanned 20 years from adolescence through adulthood. Study participants completed in-class questionnaires as students in the East Harlem area of New York City at the first wave and provided follow-up data at 4 additional points in time. 390 participants were included in these analyses; 59% female, 45% African American, and 55% Puerto Rican. Using structural equation modeling, we determined that externalizing behavior in the child was negatively related to the mutual parent–child attachment relationship for two generations of children. We also found continuity in externalizing behavior for the participant over time and from the participant to his/her child. Additionally, we found continuity in the quality of the mutual attachment relationship from the participant’s relationship with his/her parents to the participant’s relationship with his/her child. Finally, the mutual attachment relationship of the participant with his/her parents had a negative association with the participant’s externalizing behavior in adulthood. Based on these results, we propose that family interventions should focus on the role of the child’s externalizing behavior in the context of the parent–child attachment relationship. Furthermore, we suggest that prevention programs should address externalizing behavior as early as possible, as the effects of externalizing behavior in adolescence can persist into adulthood and extend to the next generation.  相似文献

Research has documented the deleterious effects of maternal depression and childhood trauma on parenting and child development. There are high rates of both depression and childhood trauma in new mothers participating in home visitation programs, a prevention approach designed to optimize mother and child outcomes. Little is known about the impacts of maternal depression and childhood trauma on parenting in the context of home visitation. This study contrasted depressed and non-depressed mothers enrolled in the first year of a home visitation program on parenting stress, quality of home environment, social network, and psychiatric symptoms. Mothers were young, low income, and predominantly unmarried. Results indicated that depressed mothers displayed impairments in parenting, smaller and less robust social networks, and increased psychiatric symptoms relative to their non-depressed counterparts. Path analyses for the full sample revealed a path linking childhood trauma, depression, and parenting stress. Path analyses by group revealed several differential relationships between dimensions of social network and parenting. Number of embedded networks, namely the number of different domains in which the mother is actively interacting with others, was associated with lowered parenting stress among non-depressed mothers and increased parenting stress in their depressed counterparts with childhood trauma histories. In depressed mothers, social network size was associated with lower levels of parenting stress but decreased quality of the home environment, whereas number of embedded networks was positively related to quality of the home environment. Implications of findings for home visitation programs are discussed.  相似文献

Behavioral flexibility is a cognitive process depending on prefrontal areas allowing adaptive responses to environmental changes. Serotonin transporter knockout (5-HTT(-/-)) rodents show improved reversal learning in addition to orbitofrontal cortex changes. Another form of behavioral flexibility, extradimensional strategy set-shifting (EDSS), heavily depends on the medial prefrontal cortex. This region shows functional changes in 5-HTT(-/-) rodents as well. Here we subjected 5-HTT(-/-) rats and their wild-type counterparts to an EDSS paradigm and a supplementary latent inhibition task. Results indicate that 5-HTT(-/-) rats also show improved EDSS, and indicate that reduced latent inhibition may contribute as an underlying mechanism.  相似文献

This study of selected episodes of Holocaust commemorations in London (UK) sheds light on the tense and ambiguous relationship between commemoration of the Holocaust and Anglo‐Jewish unity. Many have shared the aspiration for Anglo‐Jewish unity at Holocaust commemorations, but a narrow definition of “unity”, as taken to mean centralization, uniformity and consensus, has been restrictive and has not served the desired end. As these case studies demonstrate, despite the high level of cohesion achieved by the rituals of the ceremony and the collective mourning, Holocaust commemorations have also been occasions of conflict and disunity. It is the recent proliferation of commemorations in the 1990s, taking place in a diverse range of Jewish organizations and institutions rather than one combined memorial gathering, that has led to Anglo‐Jewry’s uniting in common moments of remembrance. These differing approaches to the nature, form and content of Holocaust commemorations should be perceived not only as a positive development for the future of Holocaust remembrance in Britain but also an indication of an increasingly healthy Anglo‐Jewry.  相似文献

Neonatal intensive-care unit (NICU) graduates, a group at risk for attention problems and attention-deficit hyperactivity disorder, performed an intradimensional shift card sort at 34, 42, 51, and 60 months to assess executive function and to examine effects of individual risk factors. In the “silly” game, children sorted cards (airplanes and dogs) so they were not the same as targets. In the “same” game, they did the opposite. Performance on the “silly” game was poor, especially when it was presented first. Success in following “silly” game rules improved with age and was significantly linked to maternal education and birth weight for gestational age, a measure of intrauterine stress. Degree of central nervous system injury differentiated children who completed the task from children who did not, and it also affected the need to repeat instructions in the “same” game. These results confirm an increased likelihood of impairments in executive function during preschool years in NICU graduates.  相似文献

With loss permeating the lives of all people throughout the entire life span and its potential for serious long-term deleterious effects, providing effective care for those experiencing situations of loss would be an important element of any preventive community-based mental health promotion approach.The low use of mental health services by those confronted with loss, and the lack of such services in many areas, makes it imperative to enhance the competency of the broader community to provide appropriate care during times of loss. Contributory to such care is a sound knowledge of the literature concerning loss and grieving. The broken leg analogy of grief presented in this article integrates the traditional and emerging grief theories and empirical evidence into an analogy of grieving that can be easily communicated to the general community, is relevant to many losses, and yet upholds the differing positions concerning grieving held by various schools of psychiatric thought.  相似文献

In the United States, adult entertainment striptease (also called exotic dance, nude dancing, and topless dancing) has both live and imaginary spectators. The real audience consists of those who actually enter a club (cabaret, theater), such as patrons and club personnel. However, there are people who only imagine what exotic dance is. I will comment on real and imaginary exotic dance spectators, the values they have, the actions they take that impact exotic dance, and the implications of these actions. A mosaic of contested meanings of exotic dance affects its existence or modification as well as American civil liberties. There are some feminist and uninformed imaginary spectators. Most active is an absent, imaginary audience of a segment of the politically active Christian Right that adheres to its interpretation of Scripture. Imaginary spectators are usually blind and deaf to the actual language of a dance form. Some believe exotic dance to be sinful and/or to cause crime, property depreciation, and disease, contrary to scientific evidence. These spectators’ actions in many places have destroyed the contemporary genre of exotic dance, hurt the industry economically, and caused the loss of jobs. Actual spectators, patrons who expect to see the same full nudity and sexy dance movements that are seen in “high” (“elite”) forms of art such as ballet, opera, modern dance, and theater, believe in free expression and unfettered enterprise and join the defense of exotic dance.  相似文献

We review the recent research literature on pro-criminal attitudes (PCAs) as a causal factor of recidivism with a focus on studies on the effectiveness of offender treatment programs targeting PCAs to prevent recidivism. The main conclusions that can be derived from the literature are: (1) the evidence supports the hypothesis that PCAs are related to reoffending; (2) most investigated offender treatment programs tend to reduce PCAs, although the general lack of adequate control group designs does not rule out alternative explanations for this reduction; and (3) there is no conclusive empirical evidence that intervention programs designed to reduce PCAs are effective in reducing recidivism. Empirical research in this area lacks the theoretical and methodological rigor to test causal models of the influence of treatment on reducing PCAs, and effects of PCAs on recidivism. Limitations of the empirical evidence are related to inadequate research designs and/or suboptimal data analysis strategies. Recommendations concerning optimized research designs and data analysis strategies that are likely to provide more conclusive evidence on the relation of PCAs, PCA treatment, and recidivism are given.  相似文献

Interpersonal communication plays a significant role in the maintenance of culturally shared stereotypes. This paper reports on two experiments in which two different stories were transmitted conversationally through communication chains. In both experiments, people tended to emphasize more stereotype consistent than stereotype inconsistent (SI) information, thus rendering the stories more confirming, rather than challenging, of the stereotypes. Although SI information sometimes attracted more attention in conversation, this did not translate into a greater likelihood of passing on SI information, thus keeping the story character's impression largely stereotypical even after a second retelling of the story.  相似文献
