Retention of offender DNA samples serves an important quality assurance role for forensic DNA laboratories. Consistent with the principles of confidentiality underlying the establishment of the state and national DNA databases, safeguards are in place to protect the DNA samples from unauthorized use. 相似文献

This research addresses the assumption that “general deterrence” is an important key to enhanced compliance with regulatory laws. Through a survey of 233 firms in several industries in the United States, we sought to answer the following questions: (1) When severe legal penalties are imposed against a violator of environmental laws, do other companies in the same industry actually learn about such “signal cases”? (2) Does knowing about “signal cases” change firms’ compliance‐related behavior? It was found that only 42 percent of respondents could identify the “signal case,” but 89 percent could identify some enforcement actions against other firms, and 63 percent of firms reported having taken some compliance‐related actions in response to learning about such cases. Overall, it is concluded that because most firms are in compliance already (for a variety of other reasons), this form of “explicit general deterrence” knowledge usually serves not to enhance the perceived threat of legal punishment, but as reassurance that compliance is not foolish and as a reminder to check on the reliability of existing compliance routines. 相似文献

In the presented oversight model, in which a regulatory agency may collude with regulatees, a watchdog organization may scrutinize the agency’s decision-making and find evidence speaking for collusive behavior. Found evidence is of a specific, stochastic quality. Courts will overturn the administrative decision when the evidence presented in court exceeds a minimum quality standard set by the political principal. Lowering the quality standard increases the odds of finding evidence of sufficient quality and, hence, leads to increasing collusion deterrence and to a lower probability of acquitting collusive administrators (type I error), but also to a higher probability of convicting an innocent administrator (type II error). It is shown that, when welfare-maximization gives rise to an interior solution, the welfare-maximizing standard of evidence is lower than the one that merely minimizes the costs of legal errors without taking deterrence costs into account, but will imply incomplete deterrence. However, conditions can and will be identified under which both error cost minimization and complete deterrence coincide with welfare-maximization. 相似文献

The study presents a method for the demonstration of esophageal varices at autopsy by gastroesophageal phlebography. The veins visible on the radiographs were controlled and evaluated by studying the gross appearance of sections of the esophagus at the level of the varicose veins and by histologic examination of the sections. The phlebography was found to be useful in estimating the varicose and normal veins of the esophagus. The study indicates further that the degree of varicosity is not always proportional to the severity of cirrhosis of the liver, and there may be varicose esophageal veins in patients with liver or heart disorders without hepatic cirrhosis. 相似文献

This study examined the nature of police response to domestic violence incidents with a focus on the identification of areas of police intervention that female victims of domestic abuse find “most” helpful and “least” helpful. The first part of the study was based on the analysis of a random sample of incident reports of domestic abuse cases recorded in 2000 and 2001. These reports were examined to obtain information about the characteristics of domestic abuse victims and summary information about the incidents of domestic abuse offenses. The second stage of the research study involved a telephone survey conducted with a random sample of fifty female domestic abuse victims who called the police. The study examined female victims' perceptions of how the police responded to the domestic abuse incidents, how helpful or not so helpful victims found the police to be when they responded to their calls, and how their cases were handled by the legal system. 相似文献

The purpose of this study was to examine the relationship between job demands, job resources, and burnout, and to examine if burnout could predict both work and health-related outcomes among police officers. The participants were 223 Norwegian police officers, and data were collected using a questionnaire. The study was part of a national survey of both health care and non-health care professions. The overall level of burnout was low among police officers compared to other occupational groups tested in Norway. Both job demands and job resources were related to burnout, especially work-family pressure was an important predictor for all of the three burnout dimensions. Burnout predicted individual outcomes, such as psychosomatic complaints and satisfaction with life, as well as work outcomes, such as job satisfaction, intention to quit, and organizational commitment. Suggestions for potential interventions to reduce burnout and negative individual and organizational consequences are presented. 相似文献

This paper investigates how North Korean behaviour towards boththe United States and South Korea is influenced by the popularityof the American President. The study applies theories relatingto strategic conflict avoidance and signalling to suggest thatthe American President is able to demonstrate a willingnessto use force when he is unpopular and as such is better ableto coerce Pyongyang. Using a time-series model, I demonstratethat the North Koreans become more cooperative towards the UnitedStates in response to decreases in presidential popularity andincreasing levels of US inflation. However, the study also showsthat the North Koreans do not alter their behaviour towardsthe South Koreans in response to low American President Popularityratings. The research, therefore, suggests that the North Koreansbelieve that the United States would be unable to launch a diversionaryattack in response to North Korean behaviour towards the South.This study provides a clear support for the strategic avoidanceof conflict hypothesis and suggests that the American Presidentsare best able to coerce North Korea when they are unpopularat home.

Employing a critical-mass theory of collective action, this article models the emergence of cooperation among state attorneys general in litigation against the tobacco industry. These suits were not independent events, nor was cooperation based on prior agreement among the attorneys general. Rather, cooperation emerged over time as a result of interdependent decision-making, with early lawsuits increasing the likelihood of later suits. The model emphasizes the "production function" of the collective good and the heterogeneity of the attorneys general and their political environments as keys to the development of cooperation. The model is tested against data using event history analysis. 相似文献
