Incarceration rates in the United States dramatically increased over the past several decades. This trend has drawn significant academic attention to prison overcrowding and its potential effect on inmate misconduct. The empirical relationship between inmate misconduct and overcrowding, however, is less than clear. To be sure, studies indicating positive, negative, and null relationships can all be found in the literature. The current research subjects this body of literature to a meta-analysis in an effort to: (1) clarify the direction and strength of the relationship between overcrowding and rates of prison misconduct across all studies, and (2) to uncover the degree to which variation in research outcomes can be attributed to methodological differences across studies. Results indicate that prison crowding has little substantive impact on inmate misconduct. Implications of the findings are discussed in detail.  相似文献

Many attempts have been made over the last several decades to improve communication among law enforcement agencies. This article is a case study of a “low-level” data sharing project in Florida that could serve as a national model. The Florida Law Enforcement Data Sharing Consortium is a partnership between the University of Central Florida and more than one hundred law enforcement agencies. It offers an inexpensive, yet technically advanced alternative to the proprietary data sharing model. Its distributed architecture was endorsed by the Markle Foundation, the 9/11 Commission, and the 2004 National Security Act. Civil liberties concerns raised by this and other types of data sharing projects are discussed.  相似文献

Relative to chronic hunger, seasonal hunger in rural and urban areas of Africa is poorly understood. This paper examines the extent and potential correlates of seasonal hunger in Malawi using panel data from 2011–2013. We find that both urban and rural households report seasonal hunger in the pre-harvest months. Certain strategies to smooth consumption, including crop storage and livestock ownership, are associated with fewer months of hunger. In addition, we find that Malawian households that experience seasonal hunger harvest their crops earlier than average – a short-term coping mechanism that can reduce the crop’s yield and nutritional value, possibly perpetuating hunger.  相似文献

In this essay, through an examination of its cultural situation, narrative style, and cinematic structure, I hope to explain the controversy that surrounded Roman Polanski's 1971 film version of Macbeth. With both complex cinematic semiology and poignant sociohistorical mediation, Macbeth brings to a critical juncture the philosophies of the 1960s’ peace‐love—revolution hippies, Vietnam war protestors and civil rights activists, the reified mainstream American populace, and the ruling conservatives, as well as society's preoccupation with aestheticisation. Specifically, I argue that Macbeth manifests what Gilles Deleuze calls the “crystal‐image,”; and, by extension, realises Antonin Artaud's “Theater of Cruelty,”; and, in effect, constitutes a terrorist intervention into a discursive cultural and ideological struggle. Ultimately, I argue that Macbeth itself, in totality, is a “crystalline narration”; that is shot through with various allusions to actual and virtual circumstances particular to the cultural environments from which it initially emerged in Renaissance England and then re‐emerged in the US of 1971. In the first of what is a three‐part analysis, I compare these cultural environments. The second section explicates Deleuze's theories on cinema and discusses them in conjunction with an analysis of the film's Theater of Cruelty. Finally, I contemplate the film ‘s sociopolitical implications.  相似文献

Samples containing DNA from two or more individuals can be difficult to interpret. Even ascertaining the number of contributors can be challenging and associated uncertainties can have dramatic effects on the interpretation of testing results. Using an FBI genotypes dataset, containing complete genotype information from the 13 Combined DNA Index System (CODIS) loci for 959 individuals, all possible mixtures of three individuals were exhaustively and empirically computed. Allele sharing between pairs of individuals in the original dataset, a randomized dataset and datasets of generated cousins and siblings was evaluated as were the number of loci that were necessary to reliably deduce the number of contributors present in simulated mixtures of four or less contributors. The relatively small number of alleles detectable at most CODIS loci and the fact that some alleles are likely to be shared between individuals within a population can make the maximum number of different alleles observed at any tested loci an unreliable indicator of the maximum number of contributors to a mixed DNA sample. This analysis does not use other data available from the electropherograms (such as peak height or peak area) to estimate the number of contributors to each mixture. As a result, the study represents a worst case analysis of mixture characterization. Within this dataset, approximately 3% of three-person mixtures would be mischaracterized as two-person mixtures and more than 70% of four-person mixtures would be mischaracterized as two- or three-person mixtures using only the maximum number of alleles observed at any tested locus.  相似文献

DNA profiling using STRs on the 310 and 3100 Genetic Analyzers routinely generates electropherograms that are analyzed with the GeneScan software available from the instrument's manufacturer, Applied Biosystems. Users have been able to choose from three different smoothing options that have been known to result in significant differences in the peak heights that are reported. Improvements in the underlying algorithm of the most recent version of the software also result in significant and somewhat predictable differences in peak height values. Laboratories that have performed validation studies using older versions of GeneScan should either reanalyze the data generated in those validation studies with the newest version of the software or otherwise take into consideration the systematically higher peak height values obtained as they begin following the recommendation of the manufacturer and use the new algorithm.  相似文献

An overlooked aspect of academic concern in public administration is the realm of public policy. Policy intrudes into administration at a number of crucial points; administration influences the direction and emphasis of policy in various ways. These interrelationships warrant more attention in the training of public administrators. Regrettably, they have remained largely off-limits in the training of public administrators. Why and how we should proceed to alter this state of affairs is the essence of the symposium that follows.  相似文献
