Ethical orientations that emphasize universal duties, ideals, and values are well known to public administrators. We pay attention to principle, policy, ideals, shared goals, and the provision of a variety of commonly held values, such as clean air and water, mosquito abatement, and public recreation. The word "public" often seems to be a synonym for "universal." However, this article explores particularity in ethics, especially as it applies to the life of the public servant. It identifies three distinct orientations that focus on the concrete—as opposed to the abstract—and it shows how the exceptional cases are not administrative problems; rather they provide a reality check for public administrators who suppose rules, plans, and programs to be their primary orientation toward the management of public concerns.  相似文献

Pipe bombs made from 1 mm thick copper pipe were detonated with a low explosive power powder. Analysis of the physical characteristics of fragments revealed that the copper had undergone work hardening with an increased Vickers Hardness of 107HV1 compared with 80HV1 for unexploded copper pipe. Mean plastic strain prior to fracture was calculated at 0.28 showing evidence of both plastic deformation and wall thinning. An examination of the external surface showed microfractures running parallel with the length of the pipe at approximately 100 μm intervals and 1–2 μm in width. Many larger fragments had folded “inside out” making the original outside surface inaccessible and difficult to fold back through work hardening. A visual examination for fingerprint corrosion revealed ridge details on several fragments that were enhanced by selective digital mapping of colors reflected from the surface of the copper. One of these fingerprints was identified partially to the original donor.  相似文献

The clash between social movements and political authority is often played out in the court rooms in criminal cases which are loosely described as “political trials.” While prosecutors, judges, and defendants rarely agree as to the “political” nature of a particular case, all parties usually regard the jury as the pivotal factor. The jury, of course, is enshrined in Anglo-American legal theory as the final check against suppression of liberty by the state. Plea bargaining is out of the question when the very legitimacy of the state is challenged and when dissident defendants are determined to use the trial process as a means of political expression. The crucial question is whether the jury has in fact lived up to its Constitutional role.The article attempts to answer this question at two levels. First, the history of political trials in the United States is reviewed with the general finding that radicals have faced juries which were both grossly unrepresentative of the general population and typically hostile to the ideas, life styles, and social origins of the defendants. Second, the article considers in some detail the impact of media coverage on potential jurors on one particular recent political case, the 1977–1978 trial of accused “guerrilla-bombers” Richard Picariello and Eduard Guilion in the Federal District Court of Southern Maine. The survey opinion data presented for this case strongly indicate that any chance of a fair trial for the defendants was compromised by effects of sustained hostile media coverage before the onset of the trial. Finally, the article considers available remedies in the form of either legislative reforms designed to ensure representative juries, or voir dire procedures aimed at eliminating biased jurors. A review of these remedies offers little hope that future political trials will be substantially fairer than in the past. Moreover, the direction of current criminal justice reforms, as in the proposed S-1722 Federal Criminal Code, promise to criminalize further important forms of political expression.The conclusion is not that jury trials should be avoided or minimized, since judges are apt to be even more predisposed against dissidents. Rather, the point is that the social and ideological biases which intrude especially in political trials are rooted in the political economy of capitalism which underlies the legal system itself. The jury system remains the best available defense against legal repression, but “justice” must ultimately await the outcome of continued social struggle, rather than further refinements of legal process.  相似文献

This paper assesses market liberalization in the telecommunications industry from a rent-seeking perspective. Our focus is on United States regulation, with corollary international developments that are spurring competition. The analysis which is general in approach, assesses pervasive government controls which have long shaped the nature of competition in the telecommunication sectors. We find that government has been a means for retarding competition and innovation in the telecommunications sector through the actions of rent-seeking agents. Rapid technological change, however, increasingly is rendering traditional government regulation obsolete. This change is spurring welfare-enhancing competition, regulatory reform, and privatization in the telecommunications sector.  相似文献
