In 1982, Section 2 of the U.S. Voting Rights Act was amendedto allow plaintiffs to prevail in voting rights litigation ifthey demonstrate that a challenged law or practice has a discriminatoryresult. One of the first applications of this new statutoryprovision invalidated a congressional districting plan for theNew Orleans metropolitan area, a plan that had divided the city'sblack population virtually in half. This article reviews boththe making and the unmaking of that plan, derisively known asthe "gerryduck." Although the judicial action invalidating thisexercise in racial cartography demonstrates the potential importanceof this new section of the VRA as a legal weapon against minorityvote dilution, the results test provides federal judges withenormous discretion, and the application of the test may thereforebe quite capricious. 相似文献

This paper highlights the difficulties and complexities of development assistance projects through an analysis of 2 Urban Functions in Rural Development projects conducted by the US Agency for International Development (AID) in Upper Volta and northern Cameroon in 1977-82. The general objectives of the Upper Volta project were to carry out urban function studies, develop a plan for strengthening the contributions of urban centers to rural development, develop a list of investment priorities for facilities and services, and increase the capacities of the Ministry in planning processes and methods. The 2-year project was hindered by a 1-year delay in initiating assistance due to difficulties in locating a contractor. In addition, the contractor and other team members felt there was little justification for studies of spatial organization in a country with so much evident need; rather, they focused on a small rural works program and establishment of effective local government, producing an inconsistency between team activities and the original project agreement. A request by the team to extend the project 1 year beyond its official completion date to compensate for early delays was rejected by USAID. Nonetheless, there was agreement that the project had a small positive impact in Upper Volta. Key lessons from Upper Volta were transferred to the Cameroon project. Although this project was judged to have achieved its objective of preparing a regional plan and of identifying programs for facilities, services, and small-scale enterprises, it was beset by problems of inexperience and technical underqualification of team members, poor communication, inconsistency of USAID guidelines, and methodological confusion. It is suggested that a central challenge for such programs is to create a body of qualified Americans who can work with their local counterparts in meeting the challenges of development. A measure of the success or failure of these projects should be the degree to which learning contributes to improved performance. 相似文献

Much attention has been given of late to the erosion of the "employment-at-will" doctrine. Exceptions to this doctrine began to emerge when courts held that at-will employees could sue if their termination violated public policy. The at-will doctrine was further eroded by court rulings that a contract requiring good cause in order to terminate could be inferred from employee handbooks, company personnel policies, and circumstances of employment. As the initial flood of wrongful termination lawsuits now reaches the appellate level, some guidance on the standards employers must observe can be drawn from court decisions. The authors examine these decisions as well as the legislative reform being proposed in response to them. 相似文献

The issue of whether civilly committed patients should be extended the right to accept or refuse treatment has generated much controversy and litigation during the past 15 years. In general, the current rule is that in nonemergency situations, individuals who are competent to give informed consent to treatment should be extended the right to refuse it. Obviously, the manner in which this rule is implemented partly depends on how competence to consent to treatment is defined and measured. Most researchers have implicitly assumed that an understanding of treatment information is the sole criterion of competence. It is argued that such a definition may be incomplete and is in need of reexamination. Following a review and analysis of the relevant legal and psychological literature, a comprehensive construct of competency to consent to treatment is proposed and future directions for research are discussed. 相似文献

The writings of Sir Bernard Spilsbury: Part I 总被引:1,自引:0,他引:1
W G Eckert 《The American journal of forensic medicine and pathology》1984,5(3):231-238
This is a two-part historical feature, highlighting the rare writings of Sir Bernard Spilsbury, the recognized leader of British forensic medicine in the first half of the 20th century. Parts I and II were compiled from the publications of the Medicolegal Society of Great Britain, where Sir Bernard Spilsbury served as President in 1933. Although his profile was presented previously in this Journal (vol. 2, no. 2, 179-182, 1981), it is felt that much of Sir Bernard Spilsbury's personality comes out in his writings and recordings of his speeches in the Medicolegal Society publications. Part I includes his lecture on "The Medico-Legal Significance of Bruises," presented before the Medicolegal Society in 1938; and a short case report read before the Medicolegal Society in 1924. The subject of the case report was sudden death from inhibition. Part II will contain two papers from the Medicolegal Society publications. 相似文献

The intent of this paper is to present some psychological threads which appear to be operative for the perpetrator of bite marks. In the catalogue of multiple motivations, there appears to be a current theme of power, control, potency, and the attempt to have a psychological symbolization of the perpetrator's omniscient capacity for absorbing life essences. In an examination of these highly complex needs, the modern perpetrator appears to act out consistently with cultural biases coupled with immediate psychological needs which have pressed for expression. Due to a pattern of psychologically expressed ritualism, the perpetrator will often inadvertently leave important psychological clues at the crime scene. The attack style, mode of death, characteristics of the victim, etc.--these components reveal the information on the type of psychological needs that the perpetrator is trying to satisfy. In the cases of bite marks associated with violent crime, it becomes crucial to an "investigator" what type of personality characteristics are welded together to form this kind of need complex. After reviewing cases reported in the literature and after conducting psychological interviews with perpetrators, three major groups of perpetrators seem to be apparent. The first group is motivated out of an anger track, the second group is motivated out of sadistic biting, and the third is out of the more traditional "cannibal complex" motif. 相似文献

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
