Yellowstone National Park and the surrounding mountainous region comprise the Greater Yellowstone Ecosystem (GYE), a 19 million acre area that is one of the few relatively intact ecosystems in the lower 48 states. Conservationists believe that continuation of present land management practices in the region will disrupt the ecological integrity of the GYE. Many authors have identified and described these threats, but as yet there has been no sustained effort to make sense of these threats in the context of the ongoing dynamic policy debate. We develop the foundation for such understanding by examining the implicit problem definitions that have emerged from this debate. They fall into three general categories: 1) a scientific definition, 2) an economic definition, and 3) a bureaucratic definition. This process produces an exploratory definition of the policy problem, which suggests a strategy for better understanding and policy design. We propose several intervention points at which substantive, one-the-ground improvements in the management of the GYE are possible. 相似文献

This paper critically examines the first attempt to offer general statutory protection to United Kingdom whistleblowers. Despite
some useful provisions, the paper concludes that the bill is retrogressive, unsophisticated and narrow; and that it will be
the legal profession not employees of conscience who will benefit from this instrument if it passes into law.
This revised version was published online in July 2006 with corrections to the Cover Date. 相似文献

This study was designed to analyze the effects of the environment and substrata on the quality of deoxyribonucleic acid (DNA) isolated from evidentiary specimens. The quality of DNA isolated from actual casework specimens was determined by measuring its size by agarose gel electrophoresis. The information obtained could be used to predict the suitability of the DNA in the samples for restriction fragment length polymorphism (RFLP) analysis. The evidentiary specimens chosen for DNA were classified according to substrate (scrapings, plastic bags, synthetics, denim, and carpet) and according to a subjective evaluation of the condition of the stain (soiled, damp, or putrefied) and to its size (small or large). The results show that DNA of sufficient quality and high molecular weight (HMW) can be reliably isolated from bloodstains deposited on evidentiary items which have an unknown environmental history and which have dried onto a variety of substrata. Subsequent RFLP analysis of a selected number of these samples verified that the DNA was suitable for this type of analysis. 相似文献

In what appears to be an outgrowth of the feminist movement and concomitant revelations concerning spousal abuse in America, a new concept in criminal jurisprudence, popularly known as the battered wife syndrome defense, has arisen. Increasingly, abused women who kill their husbands are claiming that their acts were justified, not solely because of the exigency of the circumstance which directly led to the death, but because of sociological, psychological, and legal factors which operate effectively to deprive them of alternatives. This note discusses the validity of the new defense in light of existing law and posits that the claim rests upon a contorted legal foundation, that it could not stand but for an invidious gender-based discrimination violative of Fourteenth-Amendment guarantees, and that it promotes family violence. 相似文献

An isoelectric focusing method is described for typing salivary amylase in liquid saliva and saliva stains. The estimated gene frequencies in a British population, calculated on the basis of three alleles operating at a single locus, were Amy 1, 0.909; Amy 2, 0.065; Amy 3, 0.026. This system may be useful in forensic investigations. 相似文献

The purpose of this study is to examine the participation of criminology and criminal justice graduate departments at the 1977-1979 American Society of Criminology meetings. Results show that institutional prestige. not productivity, is the leading predictor of meeting participation. In addition, meeting participation does not appear to be influenced by meeting site. Finally, it is suggested that criminologists focus more attention upon professional activities in order to facilitate our understanding of criminology as a science. 相似文献

The effects of changes in the minimum drinking ages in various North American jurisdictions are reviewed. The research suggests that although most teenagers have experimented with alcohol, the rates of alcohol consumption and alcohol-related traffic collisions can be increased and decreased with the drinking age control legislation. 相似文献
