Kalt and Zupan have measured ideological shirking by legislators. Here we present evidence concerning nonideological shirking. We demonstrate that representatives with more overdrawn checks tend to be more fiscally irresponsible, with fiscal irresponsibility measured by National Taxpayer Union ratings and by representatives' voting behavior on the recent House balanced budget amendment vote.  相似文献

Using a new series of data on occupational fatalities compiled by the National Institute for Occupational Safety and Health, the authors reassess value-of-life calculations based on labor market tradeoffs between fatality risks and wages. The new data are less subject to the problems of measurement error that plague previously used measures of risk. They indicate higher risk levels than previously believed and a significantly different composition of risk levels within industries. The more comprehensive risk data yield value-of-life estimates of $5 million or more—at least twice as large as estimates obtained using the Bureau of Labor Statistics risk data employed in previous studies.  相似文献

Congress intended the Americans with Disabilities Act ("ADA") to provide strong standards for addressing and eliminating discrimination against individuals with disabilities. Many commentators have concluded, however, that the federal courts are undermining the goals of the ADA by too narrowly construing membership in the statute's protected class. One example of this trend is courts' hostile treatment of ADA plaintiffs who do not use medications or devices that might alleviate their impairments ("nonmitigating plaintiffs"). Numerous district and appellate decisions have held or suggested that nonmitigating plaintiffs are not protected by the ADA. In addition, some commentators have proposed that courts should evaluate the reasonableness of a plaintiff's decision not to use mitigating measures; they argues that it is unfair to burden an employer with the cost of accommodating a disability that continues to exist only because an employee unreasonably refuses to mitigate it. Contrary to the views of these courts and commentators, however, this Comment will show that nonmitigating plaintiffs are entitled to ADA protection from employment discrimination. It argues that the statute's language, history, and structure, as well as Supreme Court precedent, demonstrate that courts cannot deny ADA protection based on a plaintiff's nonuse of available mitigating measures. It also presents several considerations that weigh against any future congressional enactment that would tie ADA protection to the reasonableness of a plaintiff's decision not to mitigate an impairment.  相似文献

The present study tested whether theoretically derived risk factors predicted increases in body dissatisfaction and whether gender moderated these relations with data from a longitudinal study of 428 adolescent girls and boys because few prospective studies have examined these aims, despite evidence that body dissatisfaction increases risk for various psychiatric disturbances. Body dissatisfaction showed significant increases for girls and significant decreases for boys during early adolescence. For both genders, parental support deficits, negative affectivity, and self-reported dietary restraint showed significant relations to future increases in body dissatisfaction. Ideal body internalization and body mass index did not demonstrate significant relations to future increases in body dissatisfaction; peer support deficits showed a marginal relation to this outcome. Gender did not moderate these relations, despite adequate power to detect interactive effects.

Accounts of general election outcomes increasingly talk about voters comparing parties in terms of their perceived competence to manage the economy and public services. This raises the question of how voters form evaluations of party competence. While it is assumed that voters form evaluations of the incumbent based on the signals provided by its current performance in office it is less clear how, in the absence of such a performance record, voters might evaluate the potential competence of the opposition. Using data from the British Election Panel Studies this article models the process by which voters form evaluations of parties' competence to manage the economy and compares results across incumbent and opposition parties. On the basis of evidence from general elections of 1992–2001 the article demonstrates that the process of evaluation formation does differ between parties in and out of power with retrospective evaluations of recent economic performance influencing evaluations of the former but not the latter. Nevertheless, the article also demonstrates that voters are capable of forming evaluations of the opposition which are more than a simple mirror image of their evaluations of the incumbent. In the absence of an up-to-date performance record these evaluations are based on long-term partisan and ideological predispositions and the cues provided by party leaders.  相似文献

Knowledge uptake, having decision makers assimilate the ideas of experts, is recognized as an important stimulus to bringing about policy change. This is particularly true in the realm of environmental policymaking, which is characterized by knowledge intensity, complexity, and multifaceted concerns. Using examples from an innovative watershed management organization, this article presents a heuristic for understanding how knowledge uptake occurs within a cycle of organizational reasoning. This cycle is driven by activities that transform data, information, and knowledge and that link specialists with decision makers. The heuristic can be used as a diagnostic tool to identify breaks in the transformation process that impede mandate fulfillment and impair capacity building. Lack of appreciation of the dynamic relationship between data, information and knowledge leads to mistimed and ineffective policy interventions that do not result in the hoped for progress in science intended to underpin policy advances.  相似文献

Puberty has been related to the onset of a variety of weight concerns and eating problems among middle school girls, including body dissatisfaction, dieting, and eating disorders. At least two models can be used to explain these relationships. The first emphasizes the timing of puberty, arguing that girls who face early puberty are particularly stressed because of the off-time nature of the event. The second focuses on synchronous events. For girls more than boys, puberty is likely to coincide with the change from elementary to middle school and/or beginning to date. Such synchronous events may create greater stress for girls. Seventy-nine girls were tested during the spring of their sixth- and eighth-grade years. Pubertal and dating status, body dissatisfaction, weight management, and eating disordered attitudes (using the Children's EAT:ChEAT) were assessed. The simple timing model (early vs. on time vs. late) was not supported. The simple synchronous model received some support in that girls with synchronous onset of menstruation and dating had higher ChEAT scores as well as greater body dissatisfaction. However, the data indicated that girls for whom puberty was early and coincidental with dating might be at unusual risk. These girls showed the highest levels of body dissatisfaction and the highest ChEAT scores.Ph.D. from Temple University.
