The positive youth development perspective, a strength-based relational developmental systems model that focuses on mutually influential relationships between individuals and contexts, has been used to study thriving across the second decade of life. However, more attention has been paid empirically to identifying the features of the individual (e.g., intentional self regulation, hope, or purpose) or to enumerating the role of context-general ecological assets than to the nature of individual-context relationships linked to thriving within specific contexts. The goal of this special section is to provide initial research reports about context-specific instances of the thriving process. The research focuses on two contexts where many youth spend a considerable amount, and often the majority, of their time—school and out-of-school time sports activities.  相似文献

Depression is a common and debilitating disorder in adolescence. Sleep disturbances and depression often co-occur with sleep disturbances frequently preceding depression. The current study investigated whether catastrophic worry, a potential cognitive vulnerability, mediates the relationship between adolescent sleep disturbances and depressive symptoms, as well as whether there are gender differences in this relationship. High school students, ages 16–18, n = 1,760, 49 % girls, completed annual health surveys including reports of sleep disturbance, catastrophic worry, and depressive symptoms. Sleep disturbances predicted depressive symptoms 1-year later. Catastrophic worry partially mediated the relationship. Girls reported more sleep disturbances, depressive symptoms, and catastrophic worry relative to boys. The results, however, were similar regardless of gender. Sleep disturbances and catastrophic worry may provide school nurses, psychologists, teachers, and parents with non-gender specific early indicators of risk for depression. Several potentially important practical implications, including suggestions for intervention and prevention programs, are highlighted.  相似文献

ABSTRACT

This paper argues that the divergent performance of the rural economies of China and India after 1950 was a product of the different capabilities of the Chinese and Indian governments to mobilize the labor force and financial resources of the rural population. By mobilizing unpaid labor and the financial resources of the villagers through mediation by the collectives (before 1984) and local administrations (from 1984 to the abolition of agricultural taxation and compulsory rural labor mobilization in 2006), the Chinese state developed rural infrastructure and the quality of the labor force at a pace and geographical scope that was far beyond its limited fiscal capacity. Efforts by the Indian state to establish rural organizations with similar mobilization capabilities failed due to the effective opposition of well-entrenched political and economic interests in the countryside. Unable to mobilize the labor and financial resources of the villagers, the Indian government relied primarily on its limited fiscal resources, which produced a much slower development of physical infrastructure and labor force quality. These are the primary reasons why China’s rural economy developed much more rapidly than India’s, which contributed significantly to the divergence of their national economies in the post-1950 era.  相似文献

The transnational agrarian social movement Vía Campesina is campaigning to have the United Nations negotiate and implement a Declaration, and eventually an International Convention, on Peasants' Rights. This article analyzes the origins and demands of the campaign and the place of the claimed rights in international law. Peasant organizations hope to follow in the footsteps of indigenous peoples' movements that participated in the negotiations preceding the 2007 UN Declaration on the Rights of Indigenous Peoples. The peasants' rights campaign has succeeded in linking its demands to discussions of the right to food in the United Nations, where concern is growing over the approach of the 2015 target for realizing the Millennium Development Goals, in particular the halving of the numbers of people suffering from hunger. The campaign is likely to face stiff resistance from powerful UN member states, but could achieve substantial advances even if the path to a convention is difficult or never completed.  相似文献
