Although adolescents often participate in multiple extracurricular activities, little research has examined how the breadth
of activities in which an adolescent is involved relates to school-related affect and academic performance. Relying on a large,
multi-ethnic sample (N = 864; 55.9% female), the current study investigated linear and non-linear relationships of 11th grade activity participation
in four activity domains (academic/leadership groups, arts activities, clubs, and sports) to adolescents’ sense of belonging
at school, academic engagement, and grade point average, contemporarily and in 12th grade. Results of multiple regression
models revealed curvilinear relationships for sense of belonging at school in 11th and 12th grade, grade point average in
11th grade, and academic engagement in 12th grade. Adolescents who were moderately involved (i.e., in two domains) reported
a greater sense of belonging at school in 11th and 12th grade, a higher grade point average in 11th grade, and greater academic
engagement in 12th grade, relative to those who were more or less involved. Furthermore, adolescents’ sense of belonging at
school in 11th grade mediated the relationship of domain participation in 11th grade to academic engagement in 12th grade.
This study suggests that involvement in a moderate number of activity domains promotes positive school-related affect and
greater academic performance. School policy implications and recommendations are discussed. 相似文献

Mexican American youth are at greater risk of school failure than their peers. To identify factors that may contribute to
academic success in this population, this study examined the prospective relationships from 5th grade to 7th grade of family
(i.e., human capital [a parent with at least a high school education], residential stability, academically and occupationally
positive family role models, and family structure) and individual characteristics (i.e., externalizing symptoms, bilingualism,
gender, and immigrant status) to the academic performance of 749 Mexican American early adolescents (average age = 10.4 years
and 48.7% were girls in 5th grade) from economically and culturally diverse families as these youth made the transition to
junior high school. Results indicated that while controlling for prior academic performance, human capital and positive family
role models assessed when adolescents were in 5th grade positively related to academic performance in 7th grade. Further,
being a girl also was related to greater 7th grade academic success, whereas externalizing symptoms were negatively related
to 7th grade academic performance. No other variables in the model were significantly and prospectively related to 7th grade
academic performance. Implications for future research and interventions are discussed. 相似文献

The longitudinal effects among self and identity processes, and between these processes and internalizing symptoms, are not well understood. As a result, the present study was designed to ascertain the over-time effects among identity commitment, reconsideration of commitments, and self-concept clarity, as well as to map the interplay of these self and identity processes with anxiety and depressive symptoms in early adolescence. A sample of 923 Dutch adolescents (mean age 12.4 years at Time 1; 49.3% female) participated at each of five annual assessments. Multivariate growth curve and cross-lagged panel models indicated that the association between self-concept clarity and commitment was bidirectional, that reconsideration occurs based on problems or dissatisfaction with self-concept clarity and with identity commitments, and that self-concept clarity (but not commitment or reconsideration) temporally precedes depressive and anxiety symptoms. Results are discussed in terms of the structure of the self-system and its associations with internalizing symptoms. 相似文献

Despite evidence that neighborhoods confer both risk and resilience for youth development, the existing neighborhood research has a number of methodological limitations including lack of diversity in neighborhoods sampled and neighborhood characteristics assessed. The purpose of this study was to address these methodological limitations of existing research and to examine the relationship of neighborhood structural and social characteristics to family-level social processes and teacher-reported social competence during early adolescence. The study sample of 3,624 fifth graders (51?% girls) was ethnically diverse, including roughly even proportions of non-Hispanic White, non-Hispanic Black, and Hispanic youth. Neighborhood measures included economic disadvantage derived from the U.S. Census, physical and social disorder obtained by direct observation, and social capital from parental reports. Family-level social processes included parent reported family cohesion and youth reported maternal and paternal nurturance. We found that neighborhood factors significantly associated with youth social aggression and social competence but not social withdrawal, after controlling for individual demographic characteristics and parenting factors. There was limited evidence of moderation of family influences by neighborhood characteristics as well as the moderation of neighborhood effects by children’s gender. Neighborhood physical disorder was associated with increased social aggression among boys but with increased social withdrawal among girls. Implications of the study’s findings for research on neighborhoods and adolescent development and the development of preventive interventions are discussed. 相似文献

Research on executive‐legislative relations in Latin America has focused on the impact of minority presidents and multiparty legislatures on legislative productivity. But an additional deadlock scenario, the blocking of a majority president by a minority through filibustering, has been understudied. This article analyzes filibustering in Costa Rica and explains the legislative paralysis in the wake of the nation's transition to a multiparty system in 2002. Legislative paralysis is seen as a product of the interaction between increased legislative fragmentation and polarization and the legislature's preexisting rules of procedure, which enable legislators easily to block bills they oppose, even when those bills are supported by supermajorities. This argument is tested through a comparison of major economic reforms in the 2000s to the reforms tackled in the 1990s. The role of filibustering, well acknowledged in U.S. politics, should also be studied in comparative politics. 相似文献

Contrary to the predictions of “power sharing” to mitigate ethnic conflicts, multicultural rights recognition can actually increase the frequency of local postelectoral mobilizations. This article demonstrates that the adoption of an ethnic rights regime for electing local government representatives may actually increase conflict if these multicultural laws are not carefully circumscribed to avoid violating human rights. Focusing on the 1995 multicultural rights reforms in Oaxaca, it presents evidence that legal changes purportedly implemented to recognize indigenous rights actually increased postelectoral disputes due to conflicts between county seat communities and peripheral population hamlets over access to funding by the central government. Based on this finding, the article addresses normative implications of “power‐sharing” multiculturalism, recommending that multicultural laws be implemented only together with legal mechanisms to solve postelectoral disputes. 相似文献

AbstractThis article employs an innovative methodology to study causal mechanisms in the oil–conflict link by combining a systematic approach with taking into account country details. Engaging in a deductive test of causal mechanisms in a controlled comparison of four major oil exporters, results show that no oil-related causal mechanism can fully explain the differences in violence. A more inductive analysis complemented by process tracing suggests a more comprehensive mechanism: oil contributes to the formation of opposition through grievances. Levels of violence, however, vary largely according to non-oil conditions – particularly the cohesiveness of opposition and the reaction of government to challengers. 相似文献

AbstractRural producer associations are considered a potential community-driven solution to the problems of smallholder agriculture. This article evaluates the impact of organising female farmers into producer associations in Gujarat, India. The initiative provided training, information, access to inputs, risk mitigation, and market linkages. Over 18 months, the programme weakly increased members’ non-farm income and access to output markets. It had stronger impacts on members’ awareness and utilisation of financial services. Impacts were heterogeneous, varying by pre-existing socioeconomic conditions. These findings suggest that producer associations can lower transaction costs for smallholders, but that poverty alleviation may be a longer-term prospect. 相似文献

This paper analyses a critical aspect of the internal functioning of five major Indian political parties, namely the nomination of candidates for parliamentary elections, focusing on the pattern of renomination of former candidates and incumbents. The data are analysed against the literature on the structure and functioning of Indian parties, and interview material on the process of nomination in the 2009 and 2004 elections. From the perspective of a six-fold typology of centralisation of nomination processes drawn from the comparative literature, it is found that all the parties analysed are in either the second-most centralised, or even most centralised categories, and that for the three major national parties, Congress, Bharatiya Janata Party and Communist Party of India (Marxist), past performance plays a role in nominations, the majority of incumbents being renominated in the post-1989 period. 相似文献

AbstractWe used survey and ethnographic data to study savings in a highly autarkic society of native Amazonians in Bolivia (Tsimane’). We equated savings with the amount of maize and rice in storage, area planted with plantains and manioc, and number of edible domesticated animals owned by a household or an adult. We found no large inter-annual change in savings possibly due to low income, impulsivity and a bundle of institutions and norms, such as borrowing, theft and reciprocity norms. The bundle attenuates the need for household formal savings at the periphery of markets. 相似文献
