Physicians who defraud and abuse medical benefit programs provide a unique group of lawbreakers for scientific study. They could be considered to epitomize white collar criminals given their exceedingly high socioeconomic status and power as a professional group. Using official reports and documents, as well as interviews with enforcement and program personnel at both state and federal levels, this study examines the problem of physician fraud and abuse in Medicare and Medicaid. Major areas relevant to understanding this phenomenon and its control are presented and policy implications of present knowledge in the area are discussed.  相似文献

Studies were carried out systematically in both corpses and the hands of corpses in order to find out when " washerwoman 's skin" begins. The temperatures ranged between 10 degrees and 18 degrees C and the time of the experiments did not exceed 300 min. The initial formation of washerwoman 's skin could be observed after 20-30 min at the fingertips and after 50-60 min in the entire finger. The longest intervals observed were 100 or 150 min, respectively. These long intervals were interpreted as being exceptions from the norm, probably due to either extraordinarily heavy strips of fat on the fingers or abnormally hard skin on the hands. The course of washerwoman 's skin obviously depends on the water temperature, and afterwards it disappears rather slowly--even after a short immersion--in the open air. We will carry out additional experiments in the future.  相似文献

One assumption of Key's reward-punishment theory that has attracted comparatively little attention is that voters hold the incumbent party responsible for all manner of economic fluctuations. A brief review of the survey literature in economic voting indicates that this assumption is in need of revision. The handful of existing studies in political science on responsibility attribution suffers from a lack of conceptual clarity and a failure to develop a theory of the attribution process. This paper outlines a model of economic voting in which people act as intuitive jurors using various decision rules to evaluate the evidence surrounding the president's responsibility for national economic problems. The generalizability of the framework and directions for future research are discussed  相似文献

This article analyzes the enforcement practices of the Investment Industry Regulatory Organization of Canada (IIROC) and compares them with its predecessor, the Investment Dealers Association of Canada (IDA). The study collected data from IIROC's tribunal cases decided between June 2008 and December 2019 and compared them with data on the IDA's enforcement of complaints from 1984 to 2008. The findings reveal no statistically significant difference in the fines imposed by the two regulatory bodies. Furthermore, IIROC has refrained from issuing lenient penalties such as retaking examinations/courses or mandating terms and conditions for offenders. The results also indicate no significant impact on the number or distribution of offense types committed in the industry over time. Most notably, the Ontario Securities Commission, the Canadian Securities Regulators, and the new Self-Regulatory Organization of Canada should consider these findings when formulating policies concerning the role of self-regulation in the financial markets.  相似文献
