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

In a recent article (Frisbie. Forbes. and Pullum 1996) we documented racial/ethnic differences in birth outcomes according to a more fine-grained classification than has typically been employed in the demographic literature. In his commentary, van der Veen focuses on the measurement of one of the dimensions of that classification, maturity of the infant. as proxied by the fetal growth ratio. The crux of the critique is easily seen in van der Veen's statement that “all of my disagreements with Frisbie et al. 's method arise from their particular use of a postnatal standard for the assessment of intrauterine growth.” Our critic misunderstands our objective: He fails to realize our interest in birth outcome, not pregnancy process, and does not perceive that our intent was to extend the research extant in both the demographic and public-health literatures in which patently postnatal (i.e., ex utero) measures are taken as outcomes interesting in their own right and/or as risk factors for infant mortality and infant and childhood morbidity. Specifically, he does recognize that we purposefully expanded our focus to include moderately compromised births to determine if they were at higher risk than the normal births with whom they are conventionally categorized. Our discussion draws on research cited in the original article, on studies cited by our critic, and on a few more recent investigations. Although we have never argued that ours is the only, or even the best, approach in all cases, we try to clarify the rationale for, and adduce additional empirical evidence of, the utility of the method we used. 相似文献

Structure and agency in development-induced forced migration: the case of Brazil’s Belo Monte Dam 总被引:1,自引:0,他引:1
Heather Randell 《Population and environment》2016,37(3):265-287
This paper examines how structure and agency interact to shape forced migration outcomes. Specifically, I ask how structural factors such as compensation policies as well as social, financial, and human capital may either foster or constrain migration aspirations and capabilities. I use longitudinal, semi-structured interview data to study forced migration among farmers displaced by the Belo Monte Dam in the Brazilian Amazon. Results from baseline interviews indicate that nearly all community members aspired to purchase rural land in the region and maintain livelihoods as cacao farmers or cattle ranchers. Constraints limiting the ability to attain aspirations included strict requirements on land titles for properties, delays in receiving compensation, rising land prices, and the lack of power to negotiate for better compensation. Despite these constraints, most migrants succeeded in attaining aspirations, as they were able to mobilize resources such as social networks, financial capital, skills, and knowledge. These findings highlight the importance of considering the relationship between structure and agency within forced migration research. I conclude by discussing how the findings may inform resettlement policies for future cases of development- or environment-induced forced migration. 相似文献

Currently, there are no psychometrically sound outcome measures by which to assess the impacts of research partnerships. This article describes the development of a 33-item, survey questionnaire measuring community members’ perceptions of the impact of research partnerships addressing health or social issues. The Community Impacts of Research Oriented Partnerships (CIROP) was developed using information from the literatures on health promotion, community development, research utilization, and community-based participatory research, and from focus groups involving 29 key informants. Data from 174 community members were used to determine the factor structure, internal consistency, and test–retest reliability of the four CIROP scales, and to provide evidence of construct validity. The CIROP informs research partnerships about the extent of their impact in the areas of Personal Knowledge Development, Personal Research Skill Development, Organizational/Group Access To and Use of Information, and Community and Organizational Development, allowing them to demonstrate accountability to funding bodies. As well, the CIROP can be used as a research tool to assess the effectiveness of knowledge sharing approaches, determine the most influential activities of research partnerships, and determine structural characteristics of partnerships associated with various types of impact. The CIROP provides a better understanding of community members’ perspectives and expectations of research partnerships, with important implications for knowledge transfer and uptake. 相似文献

Self‐reported attachment styles with mother, father, best friend, and romantic partner were assessed longitudinally across adolescence. Three cohorts (ages 13, 16, and 19 years; N=373) from a community sample were followed across 2 years. There was only one change in attachment styles with age: the oldest adolescents were more dismissive than the younger. Adolescents were more secure with mother than with father, and most dismissive and fearful with father. Boys were more dismissing than girls, who were more fearful with a romantic partner (n=158). Across time, attachment insecurity with father was associated with insecurity with a best friend. Attachment insecurity with a romantic partner was associated primarily with insecurity with friend, but changes over time tended to be associated with insecurity with mother. Results support the view of a differentiated hierarchy of attachment figures in adolescence, with the quality of parental attachment contributing to close extra‐familial relationships. 相似文献

Perceptions of injustice rely upon a sense-making process in which individuals attempt to understand why and how it occurs. We draw from the attribution-of-blame model of justice judgments to examine how two work groups of disparate status make sense of the treatment and outcomes engendered by their interactions. Data from 27 in-depth interviews with custodians and teachers reveal that when custodians perceive disrespect from teachers and teachers perceive that custodians do not fulfill properly their duties, their attributions are shaped by their status position. Although both make internal attributions to each other for their injustice, teachers do not recognize how they perpetrate injustice against custodians and custodians perceive greater injustice by identifying how external factors affect their performance and blame. This unjustified blame fosters counterproductive work behaviors, illustrating how interdependencies fuel a cycle of injustice. We discuss the implications of these findings for the school and justice processes. 相似文献
