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

Local Institutions and the Politics of Urban Growth   总被引:2,自引:0,他引:2  
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.1 In 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

Correspondence in value orientation between parents and their offspring may be due to actual transmission processes between generations, but it may also be due to influences from the general value context in society that are common to parents and their offspring. This common value context is referred to as Zeitgeist. The present study deals with one family relationship value (i.e., parents’ and adolescents’ obligations toward the family). Participants were 1,252 immigrant and 726 national adolescent–parent dyads from 10 Western countries. There were significant relationships between the value placed on family obligations among parents and offspring, and these were independent of gender. Zeitgeist effects, both intergenerational and intragenerational, were found. The strength of these Zeitgeist effects depended on the basis for defining Zeitgeist, either a person’s own ethnic group or the wider community including both nationals and immigrants. For explaining national adolescents’ acceptance of their family obligations, both the ethnic and the national Zeitgeist played a role, whereas in the immigrant groups only the ethnic Zeitgeist played a significant role. In short, in an immigration context it makes sense to distinguish the influence of a person’s own ethnic group from the influence of the wider community, including other ethnic groups. Explanations are suggested and implications are discussed.

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

This essay describes the eminent Americanist, critic, and New York intellectual, Alfred Kazin’s creation of a Lionel Trilling “character” in his 1978 autobiography, New York Jew, and his use of that character to critique significant features of the country’s Cold War literary culture. Among these are: the narrowing and hardening of intellectual discourse in a cultural-political climate dominated by the “liberal consensus,” the discrediting of the progressive impulse in American writing, the subordination of “class” to “culture” in evaluations of American writers, and the changing status of Jews and Jewish writers in post-war America. Tapping into strong personal feelings, Kazin creates in Trilling a harsh, thoughtful and compelling portrait of an era.  相似文献

As regions become more institutionalized, they are characterized by two competing trends. First, key regional institutions can become hub institutions that act as transmitters of a comprehensive set of norms. Second, as regional institutions increase in number, regions themselves are liable to become more fragmented. How these trends have played out is explored in two key regions, the Americas and the Asia-Pacific. It is concluded that regions are not static entities but are ever-changing structural arrangements. Hub institutions can be challenged and the consequences can be significant as regions gain in importance on the international stage.  相似文献
