Using personal narratives and research on teacher “communities of practice,” the authors outline a proactive response to high-stakes testing policies that places teacher learning at its center. Although research on the effects of these policies is mixed, the authors are troubled by the ways in which the policies have been used to strip teachers of their autonomy and the erosion of the value placed on their professional knowledge. The authors—who have both taught in urban schools where students had to pass high-stakes social studies tests to graduate—argue that teachers must work together to reclaim their role as leaders in response to the policies. They provide key questions that social studies teachers can use to guide an inquiry into the tests themselves and suggest ways to use the knowledge gained to better serve their students’ learning and raise test scores. 相似文献

ABSTRACT This study investigated the impact of anxiety and depression on sexual activity and substance use behaviors in a sample of 56 community- (traditional living arrangements) and foster care-dwelling adolescents aged 12 to 17 years. It was hypothesized that higher levels of anxiety and depression would be related to higher rates of risky sexual activity and substance use. Regression analyses were used to examine impact of the internalizing predictors on the risky behaviors. Results of the sample were presented with group membership emerging as a robust predictor of both sexual activity and substance use. Results suggest that adolescents within out-of-home care are at increased risk for engaging in these behaviors when compared with community-dwelling peers, and they may benefit from specific interventions aimed at decreasing participation. Future research may focus on assessing the effectiveness of interventions for these youth. 相似文献

In a study of volunteers in medical research we found contrasting readings of “being comfortable” by the volunteer research subjects and the researchers. Although the experimental process (testing a new kind of diagnostic technology) involved some physical discomfort—and the researchers focused on this—the volunteers’ concerns centred on feeling socially comfortable and managing feelings of embarrassment or isolation, and they generally made light of the physical aspects. The bias of volunteer concerns, which is understandable in terms of the different situations of researchers and volunteers and the different tensions they create, has potential implications for the engagement of researchers with their research subjects and prevailing standards for the ethical and accountable conduct of research. 相似文献

OBJECTIVE AND PARTICIPANTS: The authors investigated the effect of physical activity (PA), fruit and vegetable intake, and alcohol use on 6-month weight change in 193 college freshmen (78.8% white, 88.2% women, 94.5% on a meal plan). METHODS: The authors administered a Web-based survey in fall 2002 (baseline) and spring 2003 (follow-up). RESULTS: There was an overall average weight gain of 2.5 lbs (p < .05), although only 57% reported weight gain (M = 7.1 lbs). Fruit and vegetable intake decreased (p = .034), alcohol use increased (p > .05), and PA was unchanged. Weight gain for students with body mass indexes (BMI) > or =25 kg/m2 was nearly twice that of students with BMIs < 25 (p < .05). Students with low-frequency baseline PA were twice as likely to be overweight. Follow-up data showed that students reporting > or = 4 sessions per week (ie, high frequency) of low-intensity PA were twice as likely to have healthy BMIs as students engaging in low- and moderate-frequency PA. CONCLUSIONS: PA interventions should target freshmen with BMIs > or = 25. 相似文献

This paper evaluates the impact of federally subsidized family planning programs in the United States, from 1969 to 1974, on the reproductive behavior of ever-married women, 15–44 years old. The study began with an experimental design and the random assigment of areas to treatment and control but was completed as a multivariate analysis, treating program input as an interval-scaled independent variable. Using “before” and “after” area sample surveys and patient service data from operating programs, the demographic impact of the program was estimated. The impact detected was nonsignificant; according to our analysis, overall use of physician-administered contraception was not affected by the subsidized programs. The only program-induced change of activity related to reproduction that we recorded was increased use of subsidized services in study areas with high program input and increased use of private physician services where program input was low. These findings need to be interpreted with the caution usually exercised in evaluating imperfect field experiments. 相似文献

Social Networks,Social Cohesion,and Later-Life Health 总被引:1,自引:0,他引:1
Our study contributes to the literature acknowledging the joint role of social networks and social cohesion in shaping individual’s health, focusing on the older population aged 50 and over. Exploiting rich ego-centered social network data from the Survey of Health, Ageing and Retirement in Europe and following the conceptual model of social integration and health proposed by Berkman et al. (Soc Sci Med 51:843–857. doi:10.1016/S0277-9536(00)00065-4, 2000), we estimate multilevel models of self-reported and observer-measured later-life health outcomes. These models simultaneously account for (a) characteristics of 39,551 respondents’ personal social networks and (b) a measure of social cohesion—namely, participation in social organizations—across 57 Continental European regions, clustered in 14 countries. We find significant associations between individuals’ health and various social network characteristics (size, support, quality) as well as social cohesion. Moreover, cross-level interaction effects suggest that the social-network-health nexus is contextually bound. We conclude with a discussion of limitations and perspectives for future research. 相似文献

The issue of uncertainty has been one of the most important topics in the research on multinational enterprises' foreign market entry modes. This paper provides a conceptual review of the literature on the role of uncertainty in entry‐mode strategies. It is found that transaction cost theory has focused primarily on entry modes as a way of minimizing behavioural uncertainty, while research using the more recent real options approach has distinguished between endogenous and exogenous types of uncertainty and provided evidence that managing uncertainty through appropriate entry modes may lead to competitive advantage. By synthesizing the relevant literature, this paper provides some new perspectives and avenues for future research on uncertainty and entry‐mode choices by considering the impact of firm learning, prior experience and host market attractiveness. 相似文献
