Extracurricular activities provide a key context for youth development, and participation has been linked with positive developmental
outcomes. Using data from the 4-H Study of Positive Youth Development (PYD), this study explored how the intentional self
regulation ability of youth interacted with participation in extracurricular activities to affect PYD among adolescents living
in neighborhoods with relatively low ecological assets. In total, 545 youth were included in the study (50.3% female). Most
of the youth were European American (41%) or Latino (37%; African American, 10%; Asian American, 7%; Native American, 4%;
and other, 1%). In general, youth with the greatest capacity to self regulate benefitted the most, as compared to their peers
with less capacity to self regulate, from involvement in extracurricular activities. Consistent with a developmental systems
perspective, and specifically with bioecological theory, the findings from this study confirmed that, within lower asset settings,
children with the most positive person-level factors (intentional self regulation) benefit the most from proximal processes
such as extracurricular activity involvement. 相似文献
Intentional self regulation describes how people make choices, plan actions to reach their goals, and regulate the execution
of their actions, making processes of intentional self regulation central to healthy human functioning. Prior research has
confirmed the presence of three processes of intentional self regulation—elective selection (ES), optimization (O), and compensation
(C)—in middle adolescence (Grades 8 through 10) and concurrent and predictive relationships with measures of Positive Youth
Development (PYD). A fourth process, loss-based selection (LBS), should also develop by the end of middle adolescence. The
present study used data from the 4-H Study of PYD to confirm the presence of a four-scale structure of intentional self regulation
(ES, O, C, and LBS) in a sample of 2,357 racially diverse Grade 10 youth (63% female) and examine its covariation with indicators
of positive and problematic development. Results supported the identification of a four-part structure of intentional self
regulation, and scores covaried positively with indicators of PYD and negatively with substance use, delinquency, and depressive
symptoms. Implications of the findings for the understanding of self-regulatory actions in adolescence and for future research
are discussed. 相似文献
The riskiness of state employee pension plan portfolios varies across states. We investigate whether this variation is related to how public employees and taxpayers share actuarial surpluses of pension accounts. We focus on two determinants of a plan’s asset mix: the relative influence of public employees to taxpayers; and whether a surplus-sharing contract is specified. Our theoretical model demonstrates that the effect of public employee influence on the asset mix is ambiguous. Our empirical results corroborate this complex theoretical result. In our theoretical and empirical analyses, if a surplus sharing rule is specified, plans adopt a more aggressive investment allocation. 相似文献
This article uses a political market framework to analyze how the structure of local political institutions affects the relative political influence of development and environmental interests in the context of urban growth. Using panel data from 406 Florida cities from 1998 to 2003, the empirical analysis finds important interaction effects between the structure of city executive branch institutions and interest group variables. The economic and political forces driving urban growth do not operate identically in all cities—they vary as a function of institutional context. Institutional structure helps determine which interest groups have their preferences reflected in local land-use changes and development patterns. The resulting patterns suggest a "sustainability paradox" wherein richer, environmental interests push for the preservation of environmental amenities while at the same time accelerating the number of residential units built in a community. 相似文献
The article subjects the research rating of sociology, published in 2008 and carried out by an evaluation group on behalf of the German Science Council, to a secondary analysis. It is shown that the research rating constructs a reality of sociology which does justice neither to the variety of sociological knowledge production nor to its own claim of multidimensionality. Unwillingly, the peer reviewed article has imposed itself as the dominant criterion for assessing the research quality of research units against other types of publication and other activities such as externally funded research, knowledge transfer for practical problem-solving and knowledge diffusion in the public sphere. This preference also affected the assessment of entire research institutions with regard to their impact and efficiency as well as the devaluation of knowledge transfer and diffusion. In this way, sociology is limited to the type of professional sociology, while critical, public and policy-oriented sociology are displaced. 相似文献
Asia's growing share of the global economy provides one of the strongest themes in contemporary analysis of international affairs. The remarkable economic achievements of Japan, Korea, and Taiwan over the past 50 years have been compounded more recently by the rise of the Chinese and Indian economies. While the significance of this change in the way international wealth is shared was beyond doubt before the onset of the current global financial crisis, many commentators expect that when the world eventually emerges from the crisis Asia's share of the global economy will have grown even further.
This shift clearly has strategic importance: economic decisions made in Asia, whether by governments or business, are now more important for the rest of the world than they have been for centuries. If military power were moving in the same direction, and at the same pace, the strategic consequences would be even greater.
This paper examines trends in Asian military spending and modernisation. It begins with a summary of defence spending among Asian countries.1In this paper the term “Asia” is used to include the 22 countries from Pakistan to Japan. It does not include Afghanistan or any of the countries of central Asia, or Russia, Australia, New Zealand, or the Pacific Island countries. As explained above, data is not equally available for all 22 countries.View all notes It next considers the nature of the capabilities and equipment they are acquiring, and comments on the way in which forces are being structured, commanded, and managed. It then comments on the range of different factors that are driving military spending and modernisation in Asia, and offers particular comment on China in this regard. The paper then concludes with brief comments on United States and Australian military spending and development. 相似文献
This study examined the mediated and moderated effects of a universal family-focused preventive intervention, delivered during young adolescence, on internalizing symptoms assessed in young adulthood. Sixth grade students (N=446; 52% female; 98% White) and their families from 22 rural Midwestern school districts were randomly assigned to the experimental conditions in 1993. Self-report questionnaires were administered at seven time points (pre-test to young adulthood-age 21) to those receiving the Iowa Strengthening Families Program (ISFP) and to the control group. Results showed that growth factors of adolescent internalizing symptoms (grades 6-12) were predicted by ISFP condition and risk status (defined as early substance initiation). Moderation of the condition effect by risk status was found, with higher-risk adolescents benefitting more from the ISFP. Results also supported the hypothesis that the ISFP's effect on internalizing symptoms in young adulthood was mediated through growth factors of adolescents' internalizing symptoms; risk moderation, however, was only marginally significant in young adulthood. The relative reduction rate on clinical or subclinical levels of young adult internalizing symptoms was 28%, indicating that for every 100 young adults displaying clinical or subclinical levels of internalizing symptoms from school districts not offering an intervention, there could be as few as 72 displaying those levels of symptoms in school districts that offered middle school prevention programming. These findings highlight how the positive effects of family-focused universal interventions can extend to non-targeted outcomes and the related potential public-health impact of scaling up these interventions. 相似文献
