Power-control theory predicts gender differences in delinquency based on the level of patriarchy in the family. Tests yield mixed results, generally supporting some elements of the theory. However, because previous research does not test the theory at the family level, research does not capture within-family, as well as between-family, differences. This study, using the National Youth Survey, yields support for the use of family-level data, over individual-level data, in testing power-control theory.  相似文献

A long-standing empirical literature has been concerned with determining whether voters vote “prospectively or “retrospectively.” Despite this interest, little is known about the consequences of one voting regime versus another. This study addresses this deficiency. We find that voter welfare can be greatly affected by the candidate selection technique employed by voters. Among other findings, we show that “electing the best candidate” does not always maximize voter welfare. Furthermore, “myopic” voting is sometimes superior to “farsighted” voting. These findings have implications for interpretations of empirical studies of voter behavior.  相似文献

This essay discusses the functions of solitary media use within the ongoing daily emotional lives of adolescents. I review evidence suggesting that adolescents find in solitary TV watching and especially music listening, the opportunity, first, to cultivate a newly discovered private self: teens use media to explore numerous possible selves including those that are desired and feared. Second, I propose that solitary media experiences provide adolescents an important context for dealing with stress and negative emotion. Popular music listening allows adolescents to internalize strong emotional images around which a temporary sense of self can cohere.An earlier version of this paper was presented at the fifth biennial meetings of the Society for Research on Adolescence, San Diego, California, February 10–13, 1994. Much of the research upon which this paper is based was funded by NIMH grant No. 1 R01 MH38324 awarded to Reed Larson and Maryse Richards.Received his Ph.D. in Human Development from the University of Chicago. Research focuses on the temporal and emotional organization of daily life, especially in adolescence and within adolescents' families.  相似文献

This paper studies the behavior of average length of tenure for cohorts of U.S. representatives who entered office from 1953–1989. Using a new methodology, it addresses the following questions. How much longer do representatives stay in office now compared to, say, twenty years ago? If an increase in tenure has occurred, when did it begin? Are reelection outcomes or voluntary departures the primary determinants of changes in congressional tenure over time? The results of this study are then applied to a number of hypotheses concerning possible causes of longer congressional stays.  相似文献

This article provides the first controlled evaluation of how different information materials explaining the risks from radon influenced people's perceptions of these risks. Using a panel study, it was possible to observe how stated risk perceptions responded to information about indoor radon concentrations and brochures explaining the radon readings. The findings indicate that risk communication policies can be effective in modifying risk perceptions. Moreover, they have three specific implications for radon policy: (1) Public officials should not adopt strategies that provide minimal risk information to the public as a means of avoiding undue alarm, for this can have the reverse effect; (2) measures of the effectiveness of risk communication will depend on how education and behavior change are defined; (3) categorical guidelines about risk without quantitative information can lead people to treat the levels as thresholds, creating an artificial discontinuity in their responses to small changes in risk perceptions.  相似文献

Abstract

In the nearly 15 years since the events of 11 September 2001, the Federal Bureau of Investigation (FBI) has undertaken a succession of efforts to become an agency capable of fulfilling the intelligence functions with which it has been entrusted. However, historically, the FBI’s experience with intelligence has been reactive due to a law enforcement culture that closed cases rather than identified ways to keep opportunities for collection open, as well as bureaucratic wariness due to the differing expectations from one Presidential administration to the next. The Threat Review and Prioritization (TRP) process is the most recent iteration of the Bureau’s attempt to organize as an intelligence service. However, TRP is informed not by a mission of developing intelligence that will help to disrupt emerging threats or exploit opportunities at both the strategic (policymaking) and tactical (arrests), but instead reactively focuses on the threats which have become fully manifest within the FBI’s own domain. TRP leaves the US at a disadvantage vis-à-vis state and non-state adversaries and competitors. Organizationally, it institutionalizes the shortcomings of reactivity and insularity that were the unfortunate characteristics of the pre-9/11 FBI.  相似文献

Objectives

Our multisite randomized controlled trial reported that police body-worn cameras (BWCs) had, on average, no effect on recorded incidents of police use of force. In some sites, rates of use of force decreased and in others increased. We wanted to understand these counter-intuitive findings and report pre-specified subgroup analyses related to officers’ discretion on activating the BWCs.

Methods

Using pre-established criteria for experimental protocol breakdown in terms of treatment integrity, ten experimental sites were subgrouped into “high-compliance” (no officer discretion applied to when and where BWCs should be used; n?=?3), “no-compliance” (treatment integrity failure in both treatment and control conditions; n?=?4), and tests where officers applied discretion during treatment group but followed protocol in control conditions only (n?=?4).

Results

When officers complied with the experimental protocol and did not use discretion, use of force rates were 37 % lower [SMD?=?(?.346); SE?= .137; 95?% CI (?.614) – (?.077)]; when officers did not comply with treatment protocol (i.e., officers chose when to turn cameras on/off), use of force rates were 71 % higher [SMD?= .392; SE?= .130; 95?% CI (.136) – (.647)], compared to control conditions. When full discretion (i.e., overall breakdown of protocol) was applied to both treatment and control conditions, null effects were registered [SMD?= .009; SE=.070; 95?% CI (?.127) – (.146)], compared to control conditions.

Conclusions

BWCs can reduce police use of force when then officers’ discretion to turn cameras on or off is minimized—in terms of both case types as well as individual incidents. BWCs ought to be switched on and the recording announced to suspects at early stages of police–public interactions. Future BWCs tests should pay close attention to adherence to experimental protocols.

This article builds on recent field research to articulate a principle-based approach to environmental regulatory design that is applicable to a wide variety of circumstances, irrespective of political and social particularities. At its core, this approach recognizes that an excessive reliance on "single-instrument" policies is misguided, because all instruments have strengths and weaknesses, and none is sufficiently flexible and resilient to successfully address all environmental problems in all contexts. A better strategy is to harness the strengths of individual mechanisms while compensating for their weaknesses by the use of additional instruments. That is, in the large majority of circumstances, a mix of regulatory instruments is required, tailored to specific policy goals. The article identifies a series of regulatory design principles that sequentially address the problems and opportunities arising from the application of multi-instrument mixes and engaging a variety of first-, second-, and third-party participants in the regulatory process. The importance of choosing inherently complementary instrument combinations is also highlighted, with practical guidance provided to policymakers. Although the focus of the article is on environmental regulation, the general principles articulated should also be applicable to other areas of social regulation.  相似文献

This is an overview of the special Issue, Adolescents Uses of Media. The articles in the special issue are described as taking the uses and gratifications approach, which emphasizes that people make choices about the media they consume and that people differ in their interpretations of media content. The common goal of the articles is to integrate this approach with developmental perspectives on adolescence. Common themes include adolescents as active media users, the developmental context of adolescence, the cultural context of media use, and integrative and innovative methodological approaches.Received Ph.D. from University of Virginia. Research interests include adolescent reckless behavior, adolescents' uses of media, and the transition to adulthood.Received Ph.D. from University of Chicago.  相似文献
