This article explores the ethics and economics of a market in donated kidneys in the United States. With the impending changes in the health care system, the author argues that a full turn to the market for distribution of kidneys is not appropriate. However, he would sanction a regulated market, as outlined in the article.  相似文献

Among the most important services that psychology can offer law enforcement is assistance in the selection of future officers. The usual contribution made by police psychologists centers on the elimination of applicatns who are mentally ill. However, due to increased behavior-generated police liability, psychologists must focus on ruling out applicants whose future behavior may result in departmental compromise for any reason. One method for forecasting police officer performance is by examining critical information in biographical data. This paper examined the predictive validity of biographical information for a sample of 2,965 police officer candidates. Results indicated that several biographical variables were significantly correlated with later police officer termination. However, results of regression analyses indicated that biographical variables alone accounted for limited variance in the prediction of police officer termination. These findings suggested that the use of biographical information as a sole determinant of police candidates was not supported and the use of additional sources of data would likely be required for practical forecasting purposes.  相似文献

This paper explores the explicit self-deprecation in Vaclav Havel’s writings in order to outline a unique contribution to thinking about resistance contained in Havel’s oeuvre. What Havel offers is a timely critique of messianic political gestures. I will focus on how Havel’s self-deprecation offers a subtle but significant critique of western politics which also contains the kernal of a virtue ethics of sorts, instead of a blueprint for radical action. I will also explain the important and related critique of messianic politics entailed in Havel’s thought and outline the significance of this critique for the current political climate.  相似文献

The use of lasers for the detection of fingermarks is widespread in the forensic field. Despite this, and the fact that many studies have been conducted into the composition of fingermark residue, the components responsible for the inherent visible fluorescence remain unidentified. Traditionally compositional studies have been performed on sweat, sebum, or skin surface washes, none of which are truly representative of the situation when a fingerprint is deposited on a surface. In this paper thin-layer chromatography (TLC) has been performed on sebum-rich fingermarks laid directly onto TLC plates and an argon ion laser used to visualize the separated components. It has been found to be a robust and reproducible method for studying the fluorescent components in fingermark residue and is considered to be more realistic than other methods of sample preparation as it eliminates the chances of extraneous matter being extracted from the skin surface. Investigations into the nature of the separated compounds have also been made and the results are reported.  相似文献
