Challenging the assumption that the only motive in business is egoism (self-interest), four distinct potential prosocial motives are identified: egoism, collectivism, altruism, and principlism. It is suggested that each of these motives may, under certain nonextraordinary conditions, operate in business settings. None is a sure-fire source of ethical business practices, however. Each may at times lead to action that makes more people better off and fewer people worse off; each may also lead to action that does the opposite.I have never known much good done by those who affected to trade for the public good. It is an affectation, indeed, not very common among merchants, and very few words need be employed in dissuading them from it.—Adam Smith,The Wealthe of Nations (1776/1976), I., p. 478. 相似文献

There have been a number of papers that have reported the investigations of electrical stimulation of muscle groups in order to determine the post-mortem period. To the authors knowledge, no techniques have been described that analyse the compound action potentials (CAP) of various nerve fibre groups after death. This paper reports the monitoring of both the amplitude and latency changes of the CAP recorded from a stimulated rat sciatic nerve after death. Initial results suggest that the method my be useful in determining the early post-mortem period within 1 or 2 h after death. It may also be of use in measuring nerve conduction delay in various pathological conditions that can affect the neural network; for example diabetes. 相似文献

In the past few years postpartum phychosis has been offered as a legal defense in a small number of deeply disturbing infanticide cases in several American jurisdictions. These cases have attracted a great deal of media attention, and fueled public discussion about the mental health of mothers who kill their own babies. From the perspective of the criminologist these cases present an extraordinary pattern of criminal behavior. Not merely a few isolated incidents, but a recurring pattern of the destruction of planned-for, wanted children by their own mothers with no apparent motive and under circumstances that suggest transitory postpartum phychoses. This article presents a detailed examination of specific cases aimed at exploration of the following issues: Are these women insane at the time of the act? Is their behavior the product of a diseased state of mind, or is it premeditated and willful? These issues lie at the core of the concept of criminal responsibility. 相似文献

This study examines the prevalence of homelessness in a cross-sectional sample of 150 patients retained in a maximum-security hospital for mentally disordered offenders in New York City. The homeless mentally ill comprise only 2% of the city's mentally ill population, yet they account for 50% of the admissions to this forensic facility from the community. Compared to population base rate estimates, forensic patients are homeless at 25 times the rate found in the rest of the city's mentally disordered population and are 50 times more likely to be homeless than the general population. Further, there is a significant association between homelessness at the time of the instant offense and charges for violent crimes, after controlling for age, sex, race, and diagnosis. These data suggest that homelessness greatly increases the risk that mentally disordered persons will be forensically hospitalized and is closely associated with indictments for violent criminal behavior. Alternative explanations for these findings are discussed, emphasizing risk, vulnerability, and criminalization perspectives.Some of the data reported in this article were presented at the 42nd Annual Meeting of the American Academy of Forensic Sciences, February 24, 1990, in Cincinnati, Ohio. Thanks to Joel Dvoskin, John Monahan, Edward Mulvey, Charles D. H. Parry, Nancy Pruett, Henry Steadman, and three anonymous reviewers for their helpful comments on an earlier draft of this article. 相似文献

This article represents one of the first systematic analyses of state subsidy payments to families adopting children with special needs (children with physical and/or mental disabilities and children who are classified as hard-to-place). The analysis focuses on the monetary subsidies provided to adoptive parents of special needs children. It attempts to characterize variation in subsidy levels between counties and the impact of subsidy levels on a child's length of time until adoptive placement. The data set employed in the analysis was collected from primary sources and is one ofthe first available depositories of information on subsidy payments for special needs adoption. Results indicate that child and case characteristics explain a significant proportion of the variation in state adoption subsidy levels, but that a substantial proportion of between-county variation in subsidy levels remains unexplained. Subsidy level was not found to affect the adoption placement rate at the margin, except for children with mental disabilities. The policy implications of these results are discussed. 相似文献

The late 1970s saw the beginnings of a “scissors crisis” in public finance, i.e., a growing divergence between the expansion of government revenues and the increase in government expenditures. Unless strong measures are taken, the 1980s threaten to become the age of mega-deficits. The sluggish growth of public receipts and the buoyant development of public outlays are linked to a number of structural tendencies in the economies of the industrialized world. Efforts to close the gap have included both tax increases and expenditure cuts, but as more and more governments gain experience with the phenomenon of “fiscal cannibalism,” i.e., that taxes eat up each other, the main thrust of the counter-offensive has come to be directed against the growth of public spending. Current strategies to reinforce expenditures control include such elements as global norms, new indexing techniques, new methods of decentralizing hard choices, better methods of cash management, well-balanced policy packages, and incentives especially designed to stimulate cutbacks and policy termination. 相似文献
