In addition to being held accountable for judicial decision, courts, like other public agencies, can and should be evaluated in terms of their administrative efficiency. This paper illustrates how courts can be evaluated in terms of their relative administrative efficiency, using a new approach—data envelopment analysis (DEA)—first proposed by Charnes et al. [1]. The DEA is based upon the economic notion of Pareto optimality which states that a given decision making unit (DMU) is inefficient if some other DMU, or some combination of other DMUs, can produce at least the same amounts of all outputs with less of some resource input and not more of any other resource. Conversely a DMU is said to be efficient if the above is not possible. Charnes et al. [1] generalized the usual input/output ratio measure of efficiency for a given unit in terms of a fractional linear program with fractional constraints. In the case of courts, the efficiency of any particular court is calculated by forming the ratio of a weighted sum of outputs to a weighted sum of inputs, where the weights for both outputs and inputs are to be selected in a manner that calculates the Pareto-Koopmans efficiency of the court. This paper reviews the DEA method and illustrates its application to a data base for 100 criminal superior courts in North Carolina.  相似文献

This study evaluated the relationship between employment status (i.e., part- and full-time) and job satisfaction, with the focus on the moderating roles of perceived injury risk and injury incidence. The results found that the level of job satisfaction for full-time workers was about the same regardless of the level of injury risk they perceived. In contrast, job satisfaction of part-time workers was significantly higher when they perceived low injury risk rather than high injury risk. The findings also supported the potential adverse impact of injury incidence and injury risk on job satisfaction for both part- and full-time workers. This study highlighted the importance of understanding both workplace safety and job satisfaction when attempting to understand the differences between part-time and full-time workers.  相似文献

Over the past decade, a contentious debate regarding delayed memories of childhood sexual abuse (CSA) has existed. In order to address this debate, 240 female participants completed questions about CSA, the Dissociative Experience Scale (Bernstein & Putnam, 1986), Perceived Emotional Closeness with Perpetrator Scale (Schultz, Passmore, & Yoder, 2000), and the Gudjonsson Suggestibility Scale 2 (GSS 2) (Gudjonsson, 1987). Eighty-two (36%) reported CSA and 37% of these indicated memory disturbances for the CSA. Participants reporting memory disturbances also reported significantly higher numbers of perpetrators, chemical abuse in their families, and closer relationships with the perpetrator(s) than participants reporting no memory disturbances. Implications for clinicians working with clients reporting CSA are discussed.  相似文献

Some policy makers and policy analysts have proposed that Social Security should be privatized to enable participants to achieve higher returns through investment in the stock market. How well individual retirees would fare financially under a privatized system largely depends on their decision to invest in the equity market, rather than in other types of investment vehicles. For that reason, it is important to investigate the degree to which minority people are currently investing in this market. This article presents the findings of a study that compared the investment behavior of black and Hispanic people aged 51 to 61 with the investment behavior of their white counterparts. The major findings indicate that black and Hispanic people: (a) are less likely to invest in the equity market than are white people, and (b) tend to invest smaller percentages of their assets in the equity market. Implications for policy are discussed.  相似文献

The relative standings of four ethnic groups - Muslim Palestinians, Christian Palestinians, Asian-African Jews, European Jews -were compared, using mobility data from 1974 and 1991. The findings show that despite the lack of government support and the prevalence of inexorable discrimination against Israeli Palestinians, they have narrowed the gap with Asian-African Jews in both education and occupational prestige. This finding demonstrates that ideological and political hegemony is not always effective in improving the socio-economic standing of preferred minorities (Asian-African Jews), and that social and economic structures may counterbalance the anti-Palestinian nationalist ideology. The analysis suggests that residential and educational segregation of Palestinians protects them from direct competition with European Jews, whereas Asian-African Jews have to compete with this dominant group in schools, as well as in the labour market.  相似文献

Under appropriate long range dependence conditions, the point process of exceedances of a stationary sequence weakly converges to a homogeneous compound Poisson point process. This limiting point process can be characterized by the extremal index and the cluster-size probabilities. In this paper we address the problem of estimating these quantities and we consider the intervals estimators introduced in Ferro and Segers [2003. Inference for clusters of extreme values. J. Roy. Statist. Soc. Ser. B 545–556] and in Ferro [2004. Statistical methods for clusters of extreme values. Ph.D. Thesis, Lancaster University]. We establish asymptotic weak convergence to Gaussian random variables and we give their asymptotic variance.  相似文献

The multidimensionality of money was investigated, using exploratory factor analysis (EFA). The respondents, 290 college students from Korea, Japan, and the United States, were administered a survey, which included socio-demographic questions, and Furnham's (1984) Money Beliefs and Behaviors (MBBS) Scale. Through a series of principal components analyses, a three-factor model with 10 MBBS items was identified. The three factors, Power, Security, and Financial Modesty accounted for 53.6% of the variance. The findings have implications for college students and financial management practitioners.  相似文献

Listeria monocytogenes is a leading cause of hospitalization, fetal loss, and death due to foodborne illnesses in the United States. A quantitative assessment of the relative risk of listeriosis associated with the consumption of 23 selected categories of ready‐to‐eat foods, published by the U.S. Department of Health and Human Services and the U.S. Department of Agriculture in 2003, has been instrumental in identifying the food products and practices that pose the greatest listeriosis risk and has guided the evaluation of potential intervention strategies. Dose‐response models, which quantify the relationship between an exposure dose and the probability of adverse health outcomes, were essential components of the risk assessment. However, because of data gaps and limitations in the available data and modeling approaches, considerable uncertainty existed. Since publication of the risk assessment, new data have become available for modeling L. monocytogenes dose‐response. At the same time, recent advances in the understanding of L. monocytogenes pathophysiology and strain diversity have warranted a critical reevaluation of the published dose‐response models. To discuss strategies for modeling L. monocytogenes dose‐response, the Interagency Risk Assessment Consortium (IRAC) and the Joint Institute for Food Safety and Applied Nutrition (JIFSAN) held a scientific workshop in 2011 (details available at http://foodrisk.org/irac/events/ ). The main findings of the workshop and the most current and relevant data identified during the workshop are summarized and presented in the context of L. monocytogenes dose‐response. This article also discusses new insights on dose‐response modeling for L. monocytogenes and research opportunities to meet future needs.  相似文献
