Community-based corrections is widely heralded as the proper basis for future penal administration. Penal colonies of Finland are employed in this paper to relate changes in society at large to innovation in corrections. The penal colonies were the indirect result of the postwar crisis in Finland and changes brought by industrialization and urbanization. Unprecedented opportunities for solving problems of conventional administration motivated officials to introduce penal colonies as a means of accomodating prisons to the new expectations being imposed on correctional work. The forbearant model is proposed as a hesitant and primitive reaction to pressures to bring corrections into conformity with the trends shaping society at large. This model is useful in analyses of the American movement toward community-based corrections. 相似文献

How a society regulates Assisted Reproduction Technologies (ART) depends on cultural context. The challenge for the regulatory regime is to balance protection for patients and society with freedom for medico-scientific creativity. Neither an exclusively market-regulated nor a peer-regulated approach is realistic politically, or desirable socially, ethically and legally. Legitimate social issues that go beyond the exclusive expertise of doctors and scientists or market choice by patients need to be accommodated within the regulatory regime. Within this context, four key issues are discussed: the lack of a shared social ethic that helps the needs of the community to be balanced against those of its individual members; the negative impact of intrusive external regulation on scientists and doctors; the requirement for doctors and scientists to review their professional structures reflectively and critically if they are to be entrusted with peer-regulation; and the desirability of constructive dialogue between regulators and regulated rather than the use of coercion and criminal sanctions. 相似文献

One of the most important longstanding problems in the field of forensic medicine is the determination of the time of death upon the discovery of a possible homicide victim. With a majority of homicide victims discovered within the first 48h, it is critically important to be able to determine time of death quickly, and with accuracy and precision. Current methods of determining postmortem interval (PMI) vary, but none can provide better than an 8-h window time estimate. In this paper, the potential application of single-cell gel electrophoresis (SCGE), also known as the comet assay, to evaluate postmortem cell death processes, specifically nuclear DNA fragmentation, is assessed. Upon the death of an organism, internal nucleases contained within the cells should cause chromosomal DNA to degrade into increasingly smaller fragments over time, and if these fragments can be isolated and visualized, the fragmentation should prove to be measurable and quantifiable. An original study providing proof of the concept of postmortem DNA fragmentation between early and late time periods was conducted using human leukocytes. With an established trend seen in the leukocyte results, this study was then expanded using a porcine animal model, over a longer time period, with more frequent time-points evaluated. DNA degradation in all samples was revealed by SCGE and quantified by the use of DNA-specific quantitative stains, as measured by digital camera affixed to a microscope. The comet 'tail-moment' gave a measure of the proportion of fragmented to non-fragmented DNA, while the 'tail-length' provided the relative size of degraded DNA fragments. In both models, an increase in DNA fragmentation was found to correlate with an increased PMI from 0 to 56h postmortem, as evaluated by comet-tail-moment and by comet-tail-length, with tail-length providing the strongest statistical correlation, based upon regression analysis. The postmortem DNA fragmentation observed in this study, reveals a sequential, time-dependent process with the potential for use as a predictor of PMI in homicide cases. 相似文献

The ultimatum game is a standard instrument for laboratory experimentalists.It has been replicated in a large number of environments andpoints to special considerations for fairness. Although it hasbeen popular in the experimental community, researchers havenot harnessed all the statistical power they should to evaluatethe dynamics at work in this type of a bargaining game. Thisresearch uses two planned treatments, the first involving asignaling condition concerning a subject's "type," and the seconda price effect built into the structure of the game. We findthat there are no significant main effects as a result of thesignaling condition of a subject's type, but that there arestrong effects as a result of the different payoff parameters.Using a variety of multivariate models we find important, nonobviousinteractions with the gender of the subjects. The lesson thatwe take away from this research is that experimentalists canlearn more from data collected in the tightly controlled laboratoryenvironment by using statistical techniques that complementtheir research designs. 相似文献

The purpose of this study was to compare the effectiveness of the QIAGEN QIAamp Stool Mini Kit against a standard phenolchloroform procedure for the extraction, quantitation, and STR-typing of human nuclear DNA from human feces. Stools from six subjects were sampled by swabbing and excision. Samples extracted with the QIAamp kit gave a wide range of DNA yields, whereas those extracted by the organic method yielded no DNA. DNA was not recovered from one subject's stools by either procedure. The QIAamp extracts were amplified with the Profiler Plus and COfiler kits, and PCR inhibition was observed with DNA extracts that were further concentrated. Substitution of water or TE-4 for the QIAamp elution buffer eliminated most, if not all, of the inhibition. A modified QIAamp procedure was used to extract thirty samples, which were subjected to one of five environmental conditions. DNA was recovered from all of these samples, and typing results were obtained on 93% of the samples. 相似文献
