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

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

School engagement, or the extent to which students are involved in, attached and committed to the academic and social activities in school, plays a prominent role in preventing academic failure, promoting competence, and influencing a wide range of adolescent outcomes. Although the multidimensional nature of school engagement is well-recognized, how the three purported parts of the construct work together is largely unknown. By using data from the longitudinal, 4-H study of Positive Youth Development, involving a sample of 1,029 adolescents (67.7 % female; mean age at Grade 9 = 14.92 years; 74.4 % of participants were European American, 5.2 % were Latino/a, 7.3 % were African American), the current study examined the interrelationships of behavioral, emotional, and cognitive aspects of school engagement over three years in adolescence (Grades 9–11). We used autoregressive lagged effects models to assess the relationships among the three engagement constructs. Results indicated that behavioral and emotional engagement were related bidirectionally (each variable was a basis and an outcome of the other). In addition, behavioral engagement influenced cognitive engagement (but the reverse of this relation was not found). Implications for future research are discussed. 相似文献

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

Having an adult mentor during adolescence has been found to predict academic success. Building on previous work, the present study examined interactions between the type of mentor (i.e., kin, teacher, friend, or community), the time that mentor became important (i.e., before, during, or after high school), and the ethnicity of the protégé in predicting educational attainment in young adulthood. Analyses used Waves III and IV of the National Longitudinal Study of Adolescent Health (N = 2,409). Participants’ ages ranged from 18 to 27 (M = 21.75, SD = 1.79). The sample was 56.7 % female and nationally representative of ethnic diversity. Analyses showed that having a teacher-mentor was more predictive of educational attainment than having other types of mentors and that overall, having a mentor after high school predicts the most educational attainment. Kin- and community-mentors appeared to be more important to educational attainment during and before high school, respectively. Findings were consistent across ethnic groups. Overall, results highlight the value of teacher-mentors throughout childhood, adolescence, and early adulthood and our study further suggests that different types of mentors may be particularly useful at specific points in development. 相似文献

Positive relationships with parents and nonparental adults have the potential to bolster Black adolescents’ socio-emotional well-being. Though each type of intergenerational relationship has been linked to more positive youth outcomes, few studies have examined the interactive influences of parenting and natural mentoring relationships on the socio-emotional development of Black youth. In the current study, we examined associations between involved-vigilant parenting and the psychological well-being and social skills of Black early adolescents (n = 259; 58 % female; mean age = 13.56, SD = .96) across types of natural mentoring relationships. Using K-means cluster analysis, we identified two types of mentoring relationships (less connected and more connected) based on relationship length, involvement, closeness, and frequency of contact. Youth with more connected mentoring relationships (n = 123) had higher psychological well-being and social skills than youth with no mentor (n = 64) or less connected mentors (n = 72). Youth without a natural mentor and youth with less connected mentors did not differ in their levels of social skills or psychological well-being. Structural equation modeling was conducted to determine if associations between involved-vigilant parenting and youths’ psychological well-being and social skills varied among youth with a more connected mentoring relationship in comparison to youth without a mentor or with a less connected mentor, controlling for participants’ gender, age, school, and parental education. The positive associations between involved-vigilant parenting and adolescents’ psychological well-being and social skills were weaker among adolescents with a more connected mentoring relationship in comparison to their peers without or with a less connected mentoring relationship. These results suggest that youth may be more strongly influenced by involved-vigilant parenting in the absence of a strongly connected natural mentoring relationship. 相似文献
