Two cross-sectional studies investigated media influences on adolescents’ substance use and intentions to use substances in
the context of exposure to parental and peer risk and protective factors. A total of 729 middle school students (n = 351, 59% female in Study 1; n = 378, 43% female in Study 2) completed self-report questionnaires. The sample in Study 1 was primarily African-American
(52%) and the sample in Study 2 was primarily Caucasian (63%). Across the two studies, blocks of media-related cognitions
made unique contributions to the prediction of adolescents’ current substance use and intentions to use substances in the
future above and beyond self-reported peer and parental influences. Specifically, identification with and perceived similarity
to media messages were positively associated with adolescents’ current substance use and intentions to use substances in the
future, and critical thinking about media messages and media message deconstruction skills were negatively associated with
adolescents’ intention to use substances in the future. Further, peer influence variables (e.g., peer pressure, social norms,
peer substance use) acted as risk factors, and for the most part, parental influence variables (e.g., parental pressure to
not use, perceived parental reaction) acted as protective factors. These findings highlight the importance of developing an
increased understanding of the role of media messages and media literacy education in the prevention of substance use behaviors
in adolescence. 相似文献

The current study examined concurrent and longitudinal predictors of early adolescents’ involvement in Internet aggression.
Cross-sectional results (N = 330; 57% female) showed that the likelihood of reporting Internet aggression was higher among youth who spent more time
using Internet-based technologies to communicate with friends and who were themselves targets of Internet aggression. Offline
relational aggression and beliefs supportive of relational and physical aggression also predicted concurrent involvement in
Internet aggression. We used longitudinal data (N = 150; 51% female) to distinguish between youth who were aggressive in traditional contexts only (i.e., school) from those
who were aggressive both online and offline. These results indicated that youth who were aggressive both online and offline
were older at the initial assessment, were targets of Internet aggression, and held beliefs more supportive of relational
aggression than youth who were aggressive offline only. Implications and directions for future research are discussed. 相似文献

This study examined the effects of neighborhood context on juvenile recidivism to determine if neighborhoods influence the
likelihood of reoffending. Although a large body of literature exists regarding the impact of environmental factors on delinquency,
very little is known about the effects of these factors on juvenile recidivism. The sample analyzed includes 7,061 delinquent
male juveniles committed to community-based programs in Philadelphia, of which 74% are Black, 13% Hispanic, and 11% White.
Since sample youths were nested in neighborhoods, a hierarchical generalized linear model was employed to predict recidivism
across three general categories of recidivism offenses: drug, violent, and property. Results indicate that predictors vary
across the types of offenses and that drug offending differs from property and violent offending. Neighborhood-level factors
were found to influence drug offense recidivism, but were not significant predictors of violent offenses, property offenses,
or an aggregated recidivism measure, despite contrary expectations. Implications stemming from the finding that neighborhood
context influences only juvenile drug recidivism are discussed. 相似文献

Baumgartner and Jones (1993) showed how radically new policies emerge on government agendas as a consequence of exogenous shocks to policy subsystems displacing privileged interests. But how do these policies evolve post-punctuation? In this paper, we present three different models of policy change. Policies may revert to the old status quo if displaced interests re-assert themselves, or they may be “locked-in” by new interests now reaping the benefits. Alternatively, they may incrementally change as lawmakers “learn” how to better meet target population needs, particularly by witnessing how other jurisdictions address similar problems. We test these models with data on change in state charter schools laws over time. We find that whether old status quos are overthrow, and the fate of charter policies when they are enacted, is influenced more by competing political interests, especially interest groups, than elite and public perceptions of broad systemic crises. Yet, we also find that changing demands on the state and learning from the successes and failures of neighboring states also play significant roles. 相似文献

This article examines the structure of nonprofit voluntary accountability and standard-setting programs, arguing that these
programs can be understood as collective action institutions designed to address information asymmetries between nonprofits
and their stakeholders. Club theory and the economics of certification suggest that such programs have the potential to provide
a signal of quality by setting high standards and fees and rigorously verifying compliance. Such mechanisms can signal quality
because higher participation costs may allow only high-quality organizations to join. The article examines the implications
of signaling theory using an original dataset on the structure of 32 nonprofit accountability programs across the globe. While
many programs set high standards for compliance, the key distinction between strong and weak programs is the use of disclosure
or verification mechanisms to enforce compliance. Contrary to theoretical expectations, compliance standards and verification
do not appear to be substitutes in creating stronger voluntary programs.

The review essay takes stock of the last decade of decentralisation and regionalisation research in Central and South Eastern Europe. Classifying the existing scholarship with regard to its focus of analysis, its explanatory programme, and methodological predilections, we suggest to distinguish three different agendas: system transformation, EU conditionality and subnational governance. We argue that scholarly interest in regionalisation and decentralisation issues from the perspective of state transformation or Europeanisation is vanishing. Instead, we witness the emergence of a subnational governance approach which is rooted in comparative politics and policy analysis. The debate about decentralisation and regionalisation in CEEC is thus in a process of “normalising” and converging with the Western European subnational political discourse. 相似文献

The article reviews the state of research on public-private partnerships (PPP) which, following a development in the Anglo-Saxon countries, in the past few years have been introduced as a policy tool in Germany as well. Based on a short conceptual and historical introduction, recent political science publications as well as contributions from economic, legal, and administrative scientists are systematized and critically assessed. This also includes a review of selected publications on PPP experiences in Britain. Finally, the paper discusses relatively neglected research issues, including methodological deficits as well as problems of input legitimacy. 相似文献

As Leon Kass has noted, the conquest of illness and death has long been “the unstated but implicit goal of modern medical
science.” But it is unstated no more. Since the late 1990s, a new generation of scientists and enthusiasts has emerged to
proclaim the feasibility and desirability of radical life extension. What they promise is not just longer life, better health,
and heightened vitality, but a transformation of ourselves into the sort of beings we have long wished to be, but have repeatedly
failed to become: beings who are completely fulfilled and living in perfect harmony with others. Despite the obvious and profound
appeal of such a fantasy, attempts to realize it, even if successful scientifically, might prove to be disastrous culturally,
for reasons that go beyond concerns about the alteration of existing social structures. Ultimately, as Freud argued, life
might well become stagnant, “shallow and empty,” while the fear of death might become all the more crippling.
