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

This article identifies the arrest trajectories of youth from ages 12 through 24 years old and tests hypotheses derived from Moffitt’s developmental taxonomic theory of crime concerning the impact of various emotional disturbances on the specific trajectories of the youth involved. The study uses exclusively administrative data sets and includes a gender and racially diverse sample of 10,360 youth (30.7 % females) who were arrested at least once between ages 12 and 24 in the early 2000s. Latent class growth analysis was employed in order to identify distinct arrest trajectories of youth in the sample. Multinomial logistic regression was used to identify diagnostic and other characteristics associated with membership in the specific trajectories predicted by Moffitt’s theory. Five trajectory classes were identified, 3 of which were consistent with taxonomic theory including high and classic adolescence limited trajectory classes and a “snared adolescence limited class” described more recently by Moffitt. The distribution of youth among the 5 classes was very different for those with and without emotional disturbances. Youth with emotional disturbances in their late adolescent years were more likely to fall into the high arrest trajectory class and much less likely to fall into the low arrest trajectory class. Compared to youth without an emotional disturbance, youth with psychotic disorders were more than twice as likely to fall into the high as into the low arrest trajectory class. Youth with disruptive behavior disorders were more than twice as likely to fall into the high and intermediate classes as into the low trajectory class. Anxiety and depressive disorders were not associated with significantly greater likelihood of falling into any one of the trajectory classes. Youth in the snared adolescence limited class were more likely than those in the classic adolescence limited class to be male, black versus white and in the foster care enrollment category lending some support to Moffitt’s conceptualization of this class as an adolescence limited class composed of youth who are snared by involvement in the criminal justice and or social services systems. Implications of these results for public policy and the study of adolescence are discussed. 相似文献

The Act of Union of 1800, establishing Westminster control over Irish affairs, had important repercussions for the development of feminism within nineteenth-century Ireland, as well as contributing towards adifferentiation of Irish from British feminism. Feminism within Ireland was shaped by class, religion and racial identification: one strand followed theBritish model of Protestant philanthropy, while the other was concerned with asserting women's right to take part in nationalist political struggle. ‘Imperial’ feminists in Britain and Ireland, concerned with establishing their right to take part in the affairs of the ‘nation’, perceived those Irish who rejected British imperial rule as uncivilised, reserving sympathy for those whose economic position was threatened by the activities of those who campaigned against the landlord system. The period of the Land War of 1879–82 illustrates these conflicting discourses. The subsequent decline of imperial power in Ireland can be traced through a gradual change within Irish feminism from an initial support for the Union to a later embrace of nationalism, as young middle-class women, many from Catholic backgrounds, became involved in the movement 相似文献

References to Christian women in the English-language scholarship on the history of Japanese feminism have typically focused on one organisation, the Japan Christian Women's Reform Society. Chō Takeda Kiyoko's 1985 book, Fujin kaihō no dōhyō (Milestones for Women's Liberation), offers a more comprehensive and nuanced image of the contributions of Christian women to the elevation of women's status in pre-World War II Japan, by offering case studies of Christian women. These highlight the widespread influence of Christianity among educated men and women, the broad associational networks of the Christian community, the mutually-reinforcing connections between women's activities in the fields of education and journalism, and the personal struggles of Christian women to create a fairer and more moral society. Takeda portrays the Women's Reform Society as a foundational organisation in the history of feminism, but not the sole avenue through which Christian women worked for women's liberation. 相似文献

This paper examines whether foreign direct investment (FDI) influences confidence in commercial contracts in developing countries. While the research on how host countries’ policy environments encourage FDI inflows has flourished, scholars have paid less attention to how the policy environment and local actors’ beliefs might, in turn, be affected by FDI. This is surprising because multinational enterprises are well‐recognized political and economic actors across the world. We expect that their increasing economic salience will influence the policy environments in which they function. By employing an innovative measure of property rights protection – contract‐intensive money – we examine how foreign direct investment influences host countries’ contract‐intensive money ratio in a large panel time series of both developed and developing countries from 1980 to 2002. Our analysis suggests that higher levels of FDI inflows are associated with greater confidence in commercial contracts and, by extension, the protection of property rights in developing countries. 相似文献

The disintegration of the Soviet Union had profound economic and social effects on many of the newly independent transition economies. Nowhere was this more so than in the fisheries sector – with one of the biggest production shortfalls occurring in Kyrgyzstan, following the collapse of lake capture and pond-culture production. In 2005, aggregate landings were just 48 tonnes – barely 3 per cent of the catch level recorded in 1989. This article has two objectives. First it analyses the extent to which the dissolution of the Soviet Union can explain the collapse of the fisheries sector in Kyrgyzstan. Second, in the light of these findings, it considers what practical steps, if any, might be taken to revitalize the sector. 相似文献
