White House reporters follow a path constructed by presidential advisers that they hope will lead them to fulfill goals set by their news organizations. White House officials ration them facilities for work, access to newsworthy people, and reportable information in amounts that depend on the importance to the President of the type of media they work in, the status of their particular news organization, and the staff's respect for the influence and competence of a particular individual. In this context, several constraints that affect White House reporting are discussed here: those placed on reporters by their organizations; by the way their type of media covers the White House; by their relations with each other; and by their concepts of what they are required to do. The framework for this discussion and analysis is a classification by type of media and news organizations that assign journalists to the White House. Of the resulting six categories, the first three have the most structural and organizational influence and are given the most attention. The special status, unique history, and influence of photographers at the White House require that they be treated separately.  相似文献

The key policy question in managing hazardous technologies is often some variant of: “How safe is safe enough?” A typical response of regulatory agencies has been to lay down minimum requirements for how hazardous facilities should be built and operated, without specifying the level of safety that it is hoping to achieve. The U.S. Nuclear Regulatory Commission, charged with regulating safety in nuclear power plants, has recently tackled the safety question directly, by adopting “safety goals” that facilities must meet. The NRC's approach proves to be sophisticated in some respects, incomplete in others. More generally, it points up the inherent difficulties that exist with the concept of “acceptable risk” and with any attempt to build policy instruments around it. Lessons from the NRC case apply to other hazardous technologies, as well as to public policies unrelated to safety.  相似文献

The international community has expressed great concern about the treatment of the Uzbek minority in the south of Kyrgyzstan and has called on the majority community to make major efforts to improve the situation. The article compares the treatment of minorities in Kyrgyzstan with analogous situations in the Balkans and contends that, given the European-style ethno-national state model and democratic political system that have been adopted by independent Kyrgyzstan, such calls are unrealistic.  相似文献

A novel method for the estimation of intermediate-long firing distance range is proposed. The method is based on the characterization and chemical analysis of the smokeless powder particles on the target. An adhesive lifter is applied to collect the suspected gunshot residues (GSRs) from the surface of an object, and a Modified Griess Test (MGT) is carried out after alkaline hydrolysis on the adhesive lifter. Visualized particles are removed from the adhesive lifter under a microscope. Two systems are used for the analysis of organic discharge residues from the smokeless powder: (1) gas chromatography/thermal energy analysis (GC/TEA) for the analysis of nitroglycerine (NG) and 2,4-dinitrotoluene (2,4-DNT), (2) gas chromatography/mass spectrometry (GC/MS) for the identification of organic components such as DNT, NG, and some stabilizers. By using this procedure and confirming that the suspected particles are indeed GSR, one can estimate the intermediate-long firing distance of c. 0.75-3 m in the presence of very few particles and provide information for the classification of ammunition type in casework.  相似文献

The paper expands on an interesting phenomenon accompanying large-scale projects, namely, the parallel inflation in costs and deflation in benefits from initiation to implementation and final evaluation or elimination altogether. Historically, three explanations have been provided for the above phenomenon: the deterministic effects of uncertainty; self-interest evaluators; and the ‘vision’ factor. We claim that on face value one cannot accept as scientifically sound evidence the above three explanations of the constant decline in actual benefits. The ‘acceptance-avoidance’ model which we bring to bear predicts a constant deterioration in actual benefits as the project develops. This psychological factor results in the use of the three above-mentioned explanations as a ‘cover-up’ for real underlying human doubts regarding the chances of success of crucial decisions taken by individuals.  相似文献

During the course of a double murder trial, it became apparent that the two adhesive lifters from the two cadavers had been mislabeled before being presented in court. The question was raised whether DNA testing from the biological material remaining attached to the lifters could resolve this mix-up. In fatal shooting cases where a bullet has been fired through a body surface, an adhesive lifter is applied directly to the entrance wound. The total nitrite residues, as well as biological material surrounding the wound (blood, hair, tissue) are transferred to the adhesive lifter. The nitrite residues are used for estimating firing distance. In a worst-case scenario, the biological material on the lifter may be the only remaining reference material from a victim. In this paper, we examined whether the biological material retrieved from adhesive lifters could be used for DNA typing after the lifters had been treated for GSR pattern. In as much as the biological material found on the lifters can be typed and profiled following physical and chemical treatment, we submit that archived adhesive lifters can be used as a future source of reference DNA from cadavers where no other sample is available.  相似文献
