Contracting for prison services has been a topic of discussion for decades. Absent from this discussion is the relationship between contracting for immigration detention and confinement quality, a topic that has gained relevance as the detained immigrant population recently surpassed 440,000 per year. Detaining immigrants presents unique challenges because of detainee characteristics, the performance standards governing facilities, and the intersectoral and intergovernmental arrangements used to manage detention facilities. This research conducts the first-known large-N study that evaluates the confinement quality of U.S. Immigration and Customs Enforcement's detention facilities to determine the effect, if any, of contracting on performance. The findings suggest that all detention facilities have deficiencies that threaten the well-being of detained immigrants, but, broadly, privately contracted detention facility environments are less safe and secure than their public counterparts. The authors use contracting theory to explain why this performance disparity might exist and conclude with a discussion of the practical implications of this research. 相似文献

The identification of body fluids can be of crucial importance in forensic casework. Recently we have shown that the detection of cell- and tissue-specific mRNAs is a suitable technique to identify menstrual blood and semen. In this paper we present an improved method using real time-PCR and the menstrual blood marker MMP-7 which increases sensitivity and specificity. We furthermore demonstrate case examples described showing that the correct identification of samples as non-menstrual is likely to be in the focus of criminal investigations. Although negative test results may have a number of other reasons, the new technique provides quantitative results thus allowing a cut-off value for the control marker GAPDH to be defined, below which negative results for the menstrual blood marker MMP-7 allow the conclusion that the sample was indeed not menstrual blood. Using these data, it is possible to apply the molecular identification of menstrual blood to forensic casework considering both the limitations and the capabilities of the method. 相似文献
