Focusing on identity development explorations enables a greater understanding of contexts that affect immigrant adolescents. Utilizing thematic and grounded narrative analysis of 46 journal writings, during a one-month period, from first and second generation Vietnamese adolescents ranging in age from 15 to 18 (26 residents of a culturally and politically active ethnic enclave in Southern California; 20 adolescents living outside the enclave), this study establishes ways in which a focus on social context and exploration processes illuminates the complexity of immigrant adolescents’ identity formation. The two groups shared many similarities, including precipitants to exploration and steps undertaken to explore identity. However, two factors—social and cultural influences and emotional reactions—revealed interesting contrasts distinguishing enclave from non-enclave dwelling Vietnamese adolescents. Data also suggested that immigrant adolescents strive to integrate different domains of identity (ethnicity, gender, career) both with one another and with the historical, social, and cultural contexts they occupy.

The current cross-sectional study investigated the links between various dimensions of organized activity involvement and depressive symptoms, loneliness, and peer victimization in an ethnically and economically diverse sample of adolescents (N = 152; 58% female). Results indicate that adolescents who were involved in organized activities for more years also reported lower levels of loneliness. There was evidence of diminishing returns when adolescents were very highly involved in organized activities; those who were either under- or over-involved reported the highest levels of depressive symptoms. Conversely, findings indicate that adolescents who participated in a narrow or wide range of activity contexts reported the lowest levels of depressive symptoms. In addition, results suggested that the relation between organized activity involvement and adjustment differs among adolescents from diverse ethnic and socioeconomic backgrounds. Findings from the current study also underscore the importance of considering multiple indices of activity involvement when assessing its association with adjustment.

What motivates citizens to run for office? Recent work has shown that early life parental socialization is strongly associated with a desire to run for office. However, parents not only shape their children’s political environment, they also pass along their genes to those same children. A growing area of research has shown that individual differences in a wide range of political behaviors and attitudes are linked to genetic differences. As a result, genetic factors may confound the observed political similarities among parents and their children. This study analyzes Swedish register data containing information on all nominated and elected candidates in the ten parliamentary, county council, and municipal elections from 1982 to 2014 for a large sample of adoptees and their adoptive and biological parents. By studying the similarity in political ambition within both adoptive and biological families, our research design allows us to disentangle so-called “pre-birth” factors, such as genes and pre-natal environment, and “post-birth” factors like parental socialization. We find that the likelihood of standing as a political candidate is twice as high if one’s parent has been a candidate. We also find that the effects of pre-birth and post-birth factors are approximately equal in size. In addition, we test a number of potential pre- and post-birth transmission mechanisms. First, disconfirming our expectations, the pre-birth effects do not seem to be mediated by cognitive ability or leadership skills. Second, consistent with a role modeling mechanism, we find evidence of a strong transmission in candidacy status between rearing mothers and their daughters.  相似文献

The European Union relies on decentralised agencies to implement important transnational regulations, such as certifying the safety of medicines. However, the authority of these agencies does not have ‘hard’ legal status and crucially depends on disseminating ideas and information effectively: what can be termed ‘political entrepreneurship’. This article provides the first comprehensive analysis of the political entrepreneurship of EU agencies by constructing a conceptual typology of entrepreneurial strategies. Drawing conceptually on transnational public administration, a new database is constructed of the ‘entrepreneurship’ of 33 EU agencies in 2014 based on their media communication activities, face‐to‐face networking in workshops and collaborations, and knowledge dissemination and ‘learning’ exercises. This is mapped against the political salience of agencies in the European Parliament and media. The mapping exercise shows four types of entrepreneurial strategies covering the population of EU agencies: technical functional, insulating, network‐seeking and politicised. The typology is validated through semi‐structured interviews in 11 EU agencies, showing the core characteristics of each type of strategy. The article concludes by arguing that this typology provides an important addition to existing categories of EU agencies based on autonomy and accountability, and advocates a future research strategy examining the interaction between agencies’ entrepreneurial strategies and the expectations and reactions of stakeholder audiences.  相似文献

Pay for performance (PFP) remains one of the most controversial policy debates in the New Public Management reform era. Skepticism about PFP in the public sector is often grounded in theories of public service motivation that suggest a misalignment between PFP's focus on extrinsic market‐based pay incentives and intrinsically motivated government workers. Frequently missing from this analysis, however, is any consideration for whether PFP leads to positive “sorting” effects on the composition of a government agency's workforce through attraction, selection, and attrition processes. Using data from two waves of the Schools and Staffing Survey, the authors examine whether PFP influences the sorting patterns of K–12 public schoolteachers across U.S. school districts. Findings show that, on average, school districts that adopted PFP secured new teacher hires who had graduated from colleges and universities with average SAT scores that were about 30 points higher than the new teacher cohorts hired by districts that did not adopt PFP.  相似文献

Affluent Americans support more conservative economic policies than the nonaffluent, and government responds disproportionately to these views. Yet little is known about the emergence of these consequential views. We develop, test, and find support for a theory of class cultural norms: These preferences are partly traceable to socialization that occurs on predominantly affluent college campuses, especially those with norms of financial gain, and especially among socially embedded students. The economic views of the student's cohort also matter, in part independently of affluence. We use a large panel data set with a high response rate and more rigorous causal inference strategies than previous socialization studies. The affluent campus effect holds with matching, among students with limited school choice, and in a natural experiment; and it passes placebo tests. College socialization partly explains why affluent Americans support economically conservative policies.  相似文献

In recent years, Congress has recurrently failed to meet its minimum responsibilities in federal budgeting. This article analyzes whether it is possible to repair this problem, using concepts popularized by Allen Schick in his influential article “The Road to PPB.” His article compared the PPB reform effort to the history of budget process reforms that started with the design of the executive budget. It publicized a logical sequence of budget process improvements that started with control and then advanced through management and planning. The article did not substantially address the role of Congress, but eight years after it was published, Congress reasserted its constitutional role in the budget process. Its record of performance since then has ranged from mixed to dysfunctional. The Congress has been criticized for budgetary delays, micromanagement, myopia, procrastination, indiscipline, and an inability to prioritize intelligently. If these faults are set in stone, then an integrated system of budgeting, as described in “The Road to PPB” and related work, is unattainable. On the other hand, if reform of Congressional budgeting is politically feasible, improvements to that system can utilize the unique contributions that a legislature can make to a good system of budgeting.  相似文献

In this theoretical intervention, I argue that Karl Marx’s theory of value remains a powerful way to understand nature–society relations under capitalism. I suggest environmentalist critiques often misunderstand Marx’s value theory as a theory that “values” workers over nature. His critical theory is better understood as an explanation of how capitalist value exploits both workers and the environment. My defense of Marxian value theory is articulated through five “theses.” I provide empirical illustration based on recent research into the nitrogen fertilizer industry. (1) Value theory does not refer to all values. (2) Marx’s contention that nature does not contribute to value helps us explain its degradation under capitalism. (3) Marx’s value theory rooted in production allows for a critique of environmental economic valuation schemes (e.g. payments for ecosystem services) which are based on neoclassical value theories rooted in consumption/exchange. (4) Value is abstract social labor, but that means it also abstracts from nature. (5) Capital does value certain parts of nature and that matters. I conclude by advocating a “value theory of nature” in the spirit of Diane Elson’s powerful articulation of Marx’s “value theory of labor.”  相似文献
