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

This article approaches a position of delving into the thoughts of those who commit murder serially. The information comes
from a variety of sources which include research literature, theory examination and most importantly, serial murderers themselves.
More than 400 cases of serial fatal violence as well as interviews with incarcerated serial killers were utilized. Important
issues such as locus of motives, expected gains, victim selection processes, planning of the event, the murder event itself,
and organization and disorganization of the kill are also discussed. While admitting that serial killers have never been rehabilitated,
a call is directed toward a better understanding of the mind of the serial murderer. 相似文献

In the wake of the Gershon Report, commissioned to find ways of saving £20 billion in the UK public sector, and the growing strain on the public purse following the credit crunch and the global financial recession, procuring bodies are increasingly looking to the “shared services” procurement model to take advantage of economies of scale and best practice. This article examines the legal issues thrown up by the shared services model and ways of managing them. 相似文献

Social Utility in Ultimatum Bargaining 总被引:3,自引:0,他引:3
In this article we will provide an overview of factors that influence the weight that self-interest and equity related motives receive in ultimatum bargaining. These factors are grouped into three main categories: factors relating to the context of the game, factors relating to the parties involved, and factors related to characteristics of the game. Results of the studies are discussed in relation to the concept of social utility. The authors point out possible omissions in the literature—especially the lack of interest for the behavior of recipients—and recommend directions for future research. 相似文献

The acetaldehyde accumulation in blood during the equilibration time of samples processed by gas-liquid chromatographic headspace technique is reported. The quantitative loss of blood ethanol concentration is recorded at various temperatures and times of the preheating process.When the equilibration process is performed at 40 °C, minimal errors, due to ethanol oxidation, are observed. 相似文献
