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

Observations of high velocity bloodspatter on adjacent objects   总被引:1,自引:0,他引:1  
In a recent homicide investigation, high velocity backspatter was observed on the sleeve cuff of the accused. These minute droplets were discovered only after microscopic examination and were limited in number. A study was initiated to determine if these were truly backspatter droplets or transferred blood produced from light contact with a bloody item. It was observed that the backspattered blood was primarily limited to contact or near contact shots. An exception was a shot into an already bloody surface. It was found that backspattered blood would deposit on the shooter's shirt sleeve irrespective of the weave pattern. Transferred blood was observed only on the fiber tops. This information was found to be useful in reconstruction of events in suicides as well as possible homicides.  相似文献

This paper describes the governance system of Spanish listed firms in the early 1990's. Although the institutional setting of the Spanish Stock Exchanges differs little from other European national markets, we found important differences in several aspects of corporate governance. In particular, some of the standard mechanisms of control (e.g. boards and institutional shareholders) do not play an active role, whereas ownership is relatively concentrated. Moreover, power indices suggest that controlling blocs of large shareholders are very likely to form. We thus conclude that the ownership of shares is a pivotal mechanism in the governance of Spanish corporations.  相似文献
