Over the next decade an increasing number of new "pharmacotherapy" medications will become available with the potential to tremendously impact the use and abuse of illegal drugs and the overall direction of national and international drug policy. These pharmacotherapy medications are designed to block or significantly reduce the "highs" elicited by illegal drugs. Used as part of a drug treatment program, pharmacotherapy medications may provide valuable assistance for people voluntarily seeking a chemical aid in limiting or eliminating problem drug use. However, the tremendously politicized nature of the "drug war" raises substantial concerns that, in addition to those who voluntarily choose to use such medications, some people will be compelled to use them. This article concludes that in the absence of extraordinary circumstances, governmental action forcing or coercing a person to use a pharmacotherapy drug would violate a number of important legal rights. Among the rights implicated by compulsory use of pharmacotherapy drugs are the right to informed consent, the right to bodily integrity and privacy, the protection against cruel and unusual punishment, and the right to freedom of thought.  相似文献

This article highlights the need for an inclusive and integrated policy‐making model by drawing on the experiences of the bushfire fighting efforts of community, business and government bodies during the bushfires that ravaged North‐East Victoria during January and February of 2003 and the delivery of recovery assistance since the fires. These experiences revealed some shortfalls which militated against delivering public value for the communities affected during and after the fires. A policy framework has been developed in light of these shortfalls and is used here to reveal the ways in which bushfire management policy and practice needs to be ‘modernised’ if arrangements in the future are to deliver public value.1  相似文献

In the history of political ideas the position of Rousseau’s political theory is controversial. Many historians identify him with the utopian tradition since Thomas More stressed the collective elements in his writings. In contrast to this interpretation it is a widespread thesis that the author of the “Contrat social” must be considered as a representative of the individualistic natural rights. The following study starts with this issue. The authors show that the contractual dimension is predominant in Rousseau’s thinking but it is modified by utopian elements. So Rousseau’s “mixed paradigm” is characteristic for the second part of the 18th century when contractual realism and utopian fiction merged in the dawn of the French Revolution.  相似文献

We present the first empirical assessment of the U.K. Labour government's program of public management reform. This reform program is based on rational planning, devolution and delegation, flexibility and incentives, and enhanced choice. Measures of these variables are tested against external and internal indicators of organizational performance. The setting for the study is upper tier English local governments, and data are drawn from a multiple informant survey of 117 authorities. The statistical results indicate that planning, organizational flexibility, and user choice are associated with higher performance. Conclusions are drawn for the theory and practice of public management reform. © 2006 by the Association for Public Policy Analysis and Management  相似文献

A main goal of forensic medicine is to document and to translate medical findings to a language and/or visualization that is readable and understandable for judicial persons and for medical laymen. Therefore, in addition to classical methods, scientific cutting-edge technologies can and should be used. Through the use of the Forensic, 3-D/CAD-supported Photogrammetric method the documentation of so-called "morphologic fingerprints" has been realized. Forensic, 3-D/CAD-supported Photogrammetry creates morphologic data models of the injury and of the suspected injury-causing instrument allowing the evaluation of a match between the injury and the instrument. In addition to the photogrammetric body surface registration, the radiological documentation provided by a volume scan (i.e., spiral, multi-detector CT, or MRI) registers the sub-surface injury, which is not visible to Photogrammetry. The new, combined method of merging Photogrammetry and Radiology data sets creates the potential to perform many kinds of reconstructions and postprocessing of (patterned) injuries in the realm of forensic medical case work. Using this merging method of colored photogrammetric surface and gray-scale radiological internal documentation, a great step towards a new kind of reality-based, high-tech wound documentation and visualization in forensic medicine is made. The combination of the methods of 3D/CAD Photogrammetry and Radiology has the advantage of being observer-independent, non-subjective, non-invasive, digitally storable over years or decades and even transferable over the web for second opinion.  相似文献

Criminal psychological profiling has attained unprecedented recognition despite little empirical evidence to support its validity and the absence of any thorough exposition of the skills involved with the technique. This article reports on the empirically derived conclusions of studies that sought to examine the accuracy and skill of various groups performing a profiling task. The conclusions provide some support for the contention that professional profilers can produce a more accurate prediction of an unknown offender in comparison to other studied groups. The results also give an indication of the type of skills required for proficient profiling.  相似文献

The goal of this study was the full-body documentation of a gunshot wound victim with multislice helical computed tomography for subsequent comparison with the findings of the standard forensic autopsy. Complete volume data of the head, neck, and trunk were acquired by use of two acquisitions of less than 1 minute of total scanning time. Subsequent two-dimensional multiplanar reformations and three-dimensional shaded surface display reconstructions helped document the gunshot-created skull fractures and brain injuries, including the wound track, and the intracerebral bone fragments. Computed tomography also demonstrated intracardiac air embolism and pulmonary aspiration of blood resulting from bullet wound-related trauma. The "digital autopsy," even when postprocessing time was added, was more rapid than the classic forensic autopsy and, based on the nondestructive approach, offered certain advantages in comparison with the forensic autopsy.  相似文献
