This article explores the role of environmental concerns in free trade areas made up entirely of developing countries. It surveys the environmental institutions of Mercosur, the Common Market of South America, and its member states. It also presents a case study of the recently terminated negotiations over a regional environmental legal instrument as an example of collective environmental decisionmaking. The article concludes that all the environmental components of the agreement are weak, and have even been downgraded in recent years. Even so, national environmental protections have increased during the years of the Mercosur agreement, and some regional actors are poised to join their northern counterparts in opposition to any potential free trade area of the Americas that does not include environmental provisions.  相似文献

Prior research suggests that youths’ engagement in out-of-school time programs may be a crucial factor linking program participation to positive outcomes during adolescence. Guided by the theoretical concept of flow and by stage-environment fit theory, the present study explored correlates of engagement in youth programs. Engagement was conceptualized as the extent to which youth found the program activities enjoyable, interesting, and challenging. The current study examined how program content, monetary incentives, and youth demographic characteristics were linked to youth engagement among a sample of primarily low-income middle and high school youth attending 30 out-of-school programs (n = 435, 51 % female). Results from multilevel models suggested that program content and staff quality were strongly associated with youth engagement. Youth who reported learning new skills, learning about college, and learning about jobs through activities in the program were more engaged, as were youth who found the staff caring and competent. Results demonstrated that the link between learning content for the future and engagement was stronger for older youth than younger youth. In addition, there was a trend suggesting that providing a monetary incentive was associated negatively with youth engagement. Taken as a whole, these findings have important implications for researchers, practitioners, and policymakers interested in understanding the characteristics of out-of-school time programs that engage older youth.  相似文献

Technologically mediated contexts are social arenas in which adolescents can be both perpetrators and victims of aggression. Yet, there remains little understanding of the developmental etiology of cyber aggression, itself, as experienced by either perpetrators or victims. The current study examines 3-year latent within-person trajectories of known correlates of cyber-aggression: problem behavior, (low) self-esteem, and depressed mood, in a large and diverse sample of youth (N = 1,364; 54.6 % female; 12–14 years old at T1). Findings demonstrate that developmental increases in problem behavior across grades 8–10 predict both cyber-perpetration and victimization in grade 11. Developmental decreases in self-esteem also predicted both grade 11 perpetration and victimization. Finally, early depressed mood predicted both perpetration and victimization later on, regardless of developmental change in depressed mood in the interim. Our results reveal a clear link between risky developmental trajectories across the early high school years and later cyber-aggression and imply that mitigating trajectories of risk early on may lead to decreases in cyber-aggression at a later date.  相似文献

This study examined quality and afterschool program designs with a focus on conditions of persistent low quality. Using an action science case study method, data from a quality-improvement project were examined to explore circumstances and reasons for low quality. Four identified program designs varied by emphasis on academics, school alignment, physical space, resources, and grouping strategies, as well as by the operationalization of youth choice. These program design features were found to be dynamically interrelated and key elements of structural quality yet were not found to be targets of state, funder, or agency quality improvement interventions guided by the current broad theory of change for quality initiatives. Structural quality, conceptualized as dynamic and interdependent, may be a prerequisite condition for self-directed quality improvement or a focus of targeted quality interventions.  相似文献

Abstract

Contemporary alarm about ‘laddism’ reveals what feminist research and activism has long-recognised; universities, like other social institutions, can be dangerous places for women. Research in the US and, more recently, the UK reveals alarming rates of violence, against women, the cultural and institutional norms which support violence and gaps in institutional responses. In the midst of this contemporary alarm about the university as a hotbed of laddism, there is a risk that the university – a site of potential empowerment and liberation for women (and men) – becomes re-positioned as a danger zone. The limited focus on danger and safety belies the potential of universities to enhance human freedoms through intellectual endeavour. We argue this progressive potential should remain centre-stage, as should university-based resistance to everyday sexism and laddism. This paper analyses accounts of young women feminists (n = 33) in UK and US universities. It explores their use of feminism and features of the university environment to resist and challenge oppressive cultures and practices. It argues that, despite encroaching neoliberalism and enduring sexism, universities continue to provide environments for engagements with feminism, enabling young women students to use feminism to resist and challenge sexism and to envision their feminist futures.  相似文献

In 1965, Daniel Patrick Moynihan argued that the black family was nearing "complete breakdown" due to high rates of out-of-wedlock childbearing. In subsequent decades, nonmarital childbearing rose dramatically for all racial groups and unwed fathers were often portrayed as being absent from their children's lives. The authors examine contemporary nonmarital father involvement using quantitative evidence from the Fragile Families and Child Wellbeing Study and qualitative evidence from in-depth interviews with 150 unmarried fathers. The authors find that father involvement drops sharply after parents' relationships end, especially when they enter subsequent relationships and have children with new partners. These declines are less dramatic for African American fathers, suggesting that fathers' roles outside of conjugal relationships may be more strongly institutionalized in the black community. The challenges Moynihan described among black families some forty years ago now extend to a significant minority of all American children.  相似文献
