In the early 1970s, Grand Canyon National Park intended to designate its land to “Wilderness,” including the controversial Colorado River corridor. However, by the end of the 1970s the potential for Wilderness designation was off the table, and would never seriously return for genuine consideration. Using Schattschneider's model of conflict, we explain how the organization of this conflict privileges the “causal story” of Wilderness opponents, and therefore why the canyon is not designated. It is our contention that members of Congress will not stand forward to support Wilderness designations without simultaneously providing benefits for extractive land use because (1) congressional representatives are more penalized for supporting than opposing Wilderness designations, (2) Wilderness advocacy groups do not pressure congressional delegates as firmly as opposition groups, and (3) key local congressional members are not likely to see Wilderness as a salient issue worth the risk of negative exposure. If these findings hold, the implication is that we may have reached the end of significant Wilderness designations in highly visible areas, unless critical aspects in land use conflict change.  相似文献

The decision rendered by the International Criminal Court (ICC)Pre-Trial Chamber I on 17 January 2006 allows victims to beinvolved in ICC proceedings at an early stage of the investigation.The Prosecutor, who has filed an appeal against this decision,has consistently argued that the right of victims to participatein the proceedings does not cover the investigation phase. Itis argued that the impact of this decision goes far beyond theissue of victims’ participation in the investigations;it has general implications for the balance of power betweenthe judiciary and the prosecution in proceedings before theICC.  相似文献

Newspaper juries     
This article reports on a field experiment on the effect of media information on people’s attitudes towards the justice system. For the duration of a year a Dutch local newspaper took small groups of readers, called ‘newspaper jurors’, to court sessions of criminal cases and subsequently reported on their experiences and perceptions. Using a quasi-experimental design, we examined whether an attitude change in the general reader population of this particular local newspaper occurred as a result of the jury’s newspaper reports. Findings show that, after the treatment interval of 1 year, no attitude change in the general reader population could be identified that was absent in the control group.  相似文献

A gas chromatographic (GC) fingerprint method, based on the presence or absence of six congeners, was developed for illicit cocaine samples. The fingerprint utilizes the relative abundances of these congeners towards each other, disregarding cocaine as the main constituent, and can be expressed numerically or graphically in the form of pictograms for rapid visual comparison. The method can be applied directly to a solution of the sample in chloroform, without previous workup procedures. More than 70 unrelated samples were analyzed and a great variation was observed in the parameter composition. On the other hand, a remarkable similarity could be seen between related samples. The GC fingerprint method may be considered an important contribution for sample comparison, as is exemplified by a subdivision of the analyzed samples in different categories, based on the number and types of congeners found.  相似文献
