Objective: To help clarify the effect of gender on the bidirectional relationship between alcohol use and strenuous physical activity in college students. Participants: Five hundred twenty-four (52% female) college students recruited in August 2008 and 2009 and followed up in April 2009 and April 2011, respectively. Methods: Participants reported their alcohol use and strenuous physical activity on 2 occasions (baseline and follow-up) spaced approximately 1 or 2 years apart. Results: For females, alcohol use quantity at baseline was associated with increased strenuous physical activity at 1- and 2-year follow-ups, and alcohol use frequency at baseline was associated with decreased strenuous physical activity at 2-year follow-up. For males, alcohol use frequency at baseline predicted decreased strenuous physical activity at 1-year follow-up. Conclusions: Gender differences may be explained from an eating disorders perspective such that women use physical activity as a compensatory strategy to combat potential weight gain from calories consumed during alcohol use. 相似文献

Previous research into scratch card gambling has highlighted the effects of these games on players’ arousal and affective states. Specifically, near-miss outcomes in scratch cards (uncovering 2 of 3 needed jackpot symbols) have been associated with high levels of physiological and subjective arousal and negative emotional evaluations, including increased frustration. We sought to extend this research by examining whether near-misses prompted increases in gambling urge, and the subsequent purchasing of additional scratch cards. Participants played two scratch cards with varying outcomes with half of the sample experiencing a near-miss for the jackpot prize, and the other half experiencing a regular loss. Players rated their urge to continue gambling after each game outcome, and following the initial playing phase, were then able to use their winnings to purchase additional cards. Our results indicated that near-misses increased the urge to gamble significantly more than regular losses, and urge to gamble in the near-miss group was significantly correlated with purchasing at least one additional card. Although some players in the loss group purchased another card, there was no correlation between urge to gamble and purchasing in this group. Additionally, participants in the near-miss group who purchased additional cards reported higher levels of urge than those who did not purchase more cards. This was not true for the loss group: participants who experienced solely losing outcomes reported similar levels of urge regardless of whether or not they purchased more scratch cards. Despite near-misses’ objective status as monetary losses, the increased urge that follows near-miss outcomes may translate into further scratch card gambling for a subset of individuals . 相似文献

We analyse data from the Programme for the International Assessment of Adult Competencies to reveal that immigrants in Canada and the United States make over $200 less per month than native‐born workers. In the United States, immigrants disproportionately work in low‐wage occupations, leading to large mean national differences between immigrants and native workers. The wage differential disappears after accounting for education and cognitive skills, indicating policies must focus on reducing education and skill gaps in the United States. In Canada, an immigrant wage gap persists in nearly all occupational fields, suggesting that the better skilled and educated immigrants in Canada are not receiving the same wage premium as native workers. We close with implications for policy and future research. 相似文献

An increasing body of evidence now suggests the involvement of mitochondrial abnormalities in the etiology of neurodegenerative diseases, such as Parkinson's disease (PD) and Alzheimer disease. In this Perspective, we describe a recent study that shows that treatment of human patients with the antioxidant coenzyme Q(10'), which functions in concert with certain mitochondrial enzymes, reduced the worsening of symptoms associated with PD. These findings are consistent with the hypothesis that mitochondrial dysfunction plays a role in the pathogenesis of PD and that treatments that target mitochondrial biochemistry might ameliorate the functional decline observed in patients suffering from PD. 相似文献

This article illustrates how Uyghurs in the 1990s defined and reinforced contemporary Uyghur national identity in relation to Xinjiang's growing Han Chinese population. Adopting Barth's theory of fluid and negotiable ethnic boundaries, it focuses on the notion of change. While Uyghurs are currently activating and exaggerating certain religio-cultural differences--in particular the avoidance of pork--as a means of ensuring symbolic, spatial and social segregation from the Han, those criteria did not prevent interaction to the same extent in the past; nor do they prevent Uyghurs from making concessions when it benefits them to do so. It is argued that it is not religio-cultural differences per se that lie at the root of increased tensions between Uyghurs and Han Chinese, but changing social, political and economic contexts: on the one hand, growing Uyghur perceptions of socio-economic inequalities between themselves and the Han (the 'internal factor') and, on the other, the vast changes within the international political arena since the late 1980s (the 'external factor'). 相似文献

Food assumes enormous importance in prison: for many prisoners it conditions their life in custody and, in many respects, is symbolic of the prison experience. This article explores the complex relationship between gender, food and imprisonment through an analysis of data obtained from in‐depth interviews and group discussions conducted in three women's prisons in England. The findings indicate that, in prison, where control is taken away as the prisoner and her body become the objects of external forces, food is experienced not only as part of the disciplinary machinery, but also as a powerful source of pleasure, resistance and rebellion. The implications of such findings for health promotion in the prison context are discussed. Here, the pleasures and consolations of food may well constitute a redefinition of what it is to be healthy in this context, one that challenges the dominant meaning constructed in current health promotional discourse. 相似文献

In a series of articles, Mondak and colleagues argue that theconventional way of measuring political knowledge in surveysis flawed. Personality related "propensity to guess" underestimatesthe level of political knowledge in the population and distortsestimates of between group differences, when a DK alternativeis offered. This has led Mondak to recommend the use of closed-endeditems on which DKs are not explicitly offered, following bestpractice in the field of educational testing. In this article,we present the results of an experimental study which callsinto question the wisdom of this approach. Our results showlittle evidence of partial knowledge concealed within DK responses;when people who initially select a DK alternative are subsequentlyasked to provide a "best guess," they fare statistically nobetter than chance. We conclude that opinion researchers shouldbe cautious about adopting Mondak's recommendations for thedesign of political knowledge items in surveys. Received for publication February 22, 2005.

Urbanization poses threats to earth’s biota, and retention of remnant native habitat in protected areas within expanding urban boundaries may help alleviate threats to wildlife. However, it is unclear for nearly all nonsynanthropic (i.e., not benefiting from an association with humans) species whether vital rates in urban habitats can sustain populations or if populations persist only through immigration from outside the urban boundary. We conducted a three-year study of spotted towhees (Aves: Pipilo maculatus) breeding in four undeveloped parks in Portland, OR, USA, to measure park-specific seasonal reproductive output (F) and annual adult survival (SA). We developed a stochastic model that combined F and SA with an estimate of first-year survival to measure population growth rate (λ) in all parks assumed to be closed to immigration. F differed among parks but SA did not. Relatively high F was possible because many pairs raised >1 brood/season. When combined with empirical estimates of survival through the 30-day period of post-fledging parental care (SD = 0.645), only 2 of 4 parks were self-sustaining (i.e., λ > 1.0). However, SD reflected substantial loss of fledglings to domestic cats (Felis catus). Assuming no loss to cats and either partial compensatory or additive mortality of fledglings substantially improved prospects of population persistence for declining (sink) populations. Moreover, allowing low levels of immigration to sinks reversed population declines in most parks even when vital rates were insufficient to maintain populations. Our results suggest that nonsynanthropic bird species can persist in urban landscapes, but also that offspring mortality in the post-fledging period may be a critical determinant of population viability. 相似文献

How is ‘authentic’ linguistic femininity in Japan manifested in popular texts? We analyze the dialogue of female characters in Wakaba, a 2005 Japanese drama set in two very different parts of ‘regional’ Japan – Miyazaki and Kobe. Through this analysis, we examine two contradictory discourses circulated through popular media. The first is that linguistic femininity is based in Standard Japanese – a surprisingly persistent ideology despite a current trend to examine cases in which language ideology and practice do not match. Other studies reflect another dominant discourse, that of the ‘authentic’ dialect speaker, who expresses local alignment by using dialect forms outside the bounds of ideologically modern linguistic forms. The tension between acting linguistically feminine and ‘authentically’ local raises some interesting questions for Japanese language and gender studies, including studies of gendered representations: are women who are speakers of regional dialects authentically ‘feminine’? Can they be? Do some dialects express femininity better than others? 相似文献
