The manner in which agenda change occurs demonstrates how institutional arrangements influence agenda priorities in the Supreme Court and Courts of Appeals. A neo-institutional theoretic perspective is employed to examine the dynamics of agenda formation in these courts. The article finds that the Supreme Court's agenda choices influence the decisions of litigants, interest groups, and lawyers to appeal certain cases to the Courts of Appeals. While the Supreme Court's agenda primarily is influenced by internal factors, it is constrained by agenda changes in the appeals courts. Critically, it is shown that these federal appellate courts exist within an endogenous system with respect to agenda formation, as both courts respond to agenda changes made in the other over time.  相似文献

"Brain death," the determination of human death by showing the irreversible loss of all clinical functions of the brain, has become a worldwide practice. A biophilosophical account of brain death requires four sequential tasks: (1) agreeing on the paradigm of death, a set of preconditions that frame the discussion; (2) determining the definition of death by making explicit the consensual concept of death; (3) determining the criterion of death that proves the definition has been fulfilled by being both necessary and sufficient for death; and (4) determining the tests of death for physicians to employ at the patient's bedside to demonstrate that the criterion of death has been fulfilled. The best definition of death is "the cessation of functioning of the organism as a whole." The whole-brain criterion is the only criterion that is both necessary and sufficient for death. Brain death tests are used only in the unusual case in which a patient's ventilation is being supported. Brain death critics have identified weaknesses in its formulation. But despite its shortcomings, the whole-brain death formulation comprises a concept and public policy that make intuitive and practical sense and that has been well accepted by many societies.  相似文献

This paper describes an effort by industry and university partners to centralize manufacturing decision making through the development of generic simulation tools. This ongoing, cooperative process improvement initiative between the Industrial and Systems Engineering faculty at the University of Alabama in Huntsville (UAH) and Chrysler’s Huntsville Electronics Division (HED) permits the involved faculty to broaden their experience and technical expertise in electronics fabrication, while the industry partner benefits from the transfer of technical knowledge and advanced analysis methodologies from the university. The focus of the project is the definition of generic electronic manufacturing models that can be easily defined and implemented through common user-oriented interfaces, allowing users who are not familiar with simulation and simulation languages to address the needs of their particular functional areas.  相似文献

This paper describes a collaborative exercise intended to demonstrate whether uniformity of DNA profile results could be achieved between different European laboratories. It was shown that this goal can be obtained provided that a common protocol is followed (specifically the use of a common electrophoretic buffer as being the most important parameter). Generally, lower molecular weight loci (with lower molecular weight fragments) such as YNH24 perform better than higher molecular weight loci such as MS43a. The results of the exercise are discussed in relation to the objectives of the European DNA profiling group (EDNAP).  相似文献

This article examines the extent to which changes in distributional benefits influence congressional election outcomes. Although conventional wisdom holds that a direct link exists between distributional benefits and electoral outcomes (Mayhew 1974b), recent evidence suggests that this link only exists under certain circumstances (Stein and Bickers 1994). In this article, I use 1995 military base closures to test the nature of the relationship. Contrary to recent research on the politics of pork barreling, my findings indicate support for a direct relationship between major base realignments and closures and House electoral outcomes. Specifically, major realignments and closures significantly decreased first‐year Democrats' vote margins in the 1996 House elections.  相似文献

Abstract. Western natural law theory emphasises the derivation of principles of right action said to be universal and objective from the application of practical reasonableness to the pursuit of basic human goods that are self‐evident or based on human nature. Critics say its methodology is inherently subjective. In contrast, the Vedic approach to natural law of the Bhagavad‐Gita emphasises the full development of a universal aspect of human nature—consciousness—to promote right action. A healthy person with a developed intellect, clear mind, balanced emotions and full perception is best placed to fulfil his or her society's highest ideals of ethical and lawful conduct. The Vedic approach advocates a supportive social environment and the use of meditation techniques to promote such development. Research has found that the Transcendental Meditation (TM) program promotes improvement in mind, body and behaviour. For example, offenders in Australia, the United States and Senegal practising the technique experienced decreased substance abuse and recidivism and improved wellbeing. From a scientific perspective, TM promotes these improvements by producing a unique psychophysiological state of restful alertness that dissolves stress that blocks the unfoldment of full potential in life.  相似文献
