Compared to the practice in other professional schools and academic fields at universities, law professors are hired at a young age based primarily upon their academic merit determined through grades, class rank, and school rank. This emphasis upon narrowly defined academic merit—apart from achievement demonstrated through original scholarship or experience in professional practice—first emerged during "the professionalization of the American law professor" between 1870 and 1900 at Harvard Law School (HLS). Though normative today, this outcome was neither necessary nor uncontested. In the late nineteenth century the new standard of hiring faculty according to their academic merit was energetically opposed by those favoring the antecedent standard of professional experience and reputation. Only when financial considerations counterbalanced that traditional standard did hiring decisions tip in favor of the new principle. Not until the early 1900s, when the second generation of academic meritocrats dominated the HLS faculty, did the new hiring standard become unequivocally established as policy in the school and, by extension, in legal education. 相似文献

Ethanol was determined by gas chromatography in a variety of tissues and body fluids secured at autopsy in 61 cases. The specimens tested included right and left heart blood, femoral blood, pericardial fluid, cerebrospinal fluid, vitreous humor, urine, stomach contents, and brain. Statistical analysis of the cases revealed no significant differences among the various blood sites tested. However, the variations in blood ethanol concentrations among the various sampling sites within each case were as follows: 40 cases showed differences of less than 25%; 16 cases revealed variability between 25% and 50%, 4 cases had differences exceeding 50%. In one case, satisfactory blood analyses could not be accomplished. The larger variances occurred especially in those instances in which stomach alcohol concentration was 0.50% or greater. In one case, the variability amongst the different blood sites exceeded 400% (femoral blood--0.043%, right atrium--0.070%, root of aorta--0.156%); the brain was 0.050%, and the stomach contents was 1.2%. For all 61 cases, variances in blood alcohol content among the different sampling sites in a single cadaver ranged from 1.8 to 428%. 相似文献

Recently criminologists have begun to explore the importance of disaggregating frequency measures of self-reported delinquency into the separate decisions of initiation and continuation. Given that labeling makes predictions concerning continuation, the purpose of this paper is twofold. The first is to test the ability of an informal labeling model to predict the decision to continue delinquent behavior once it is initiated. The second purpose is to address the broader question of whether disaggregation matters. The findings support the idea that the informal labeling model is predictive of the decision to continue delinquent behavior. The findings also suggest that, at least for a measure of general delinquency, there are some differences to be found by choosing the appropriate sample and form of the dependent variable. 相似文献

Do Lawyers Cause Adversarial Legalism? A Preliminary Inquiry 总被引:2,自引:1,他引:1
Robert A. Kagan 《Law & social inquiry》1994,19(1):1-62
Cross-national case studies have indicated that compared to other economically advanced democracies, American methods of policy implementation and dispute resolution are more adversarial and legalistic, shaped by costly court action or the prospect of it. To what extent are lawyers responsible for creating American-style adversarial legalism? This article argues that while adversarial legalism stems primarily from enduring features of American political culture and governmental structure, the legal profession plays a significant independent role in promoting and perpetuating this mode of governance. 相似文献

This article investigates the effect of Computer Assisted Monitoring of Offenders (CAMO) on probation outcome. In a comparison
sample, the effect of CAMO treatment is compared to the effect of “regular” probation. In addition to testing the effects
of CAMO as an intermediate treatment, methodological issues, such as level of probation restrictiveness and the effects of
prior criminal involvement on probation outcome, are tested. Although the results are mixed, they indicate that level of probation
restrictiveness and prior criminal involvement have a greater effect on probation outcome than does CAMO. These findings have
ramifications for researchers comparing CAMO probationers to “regular” probationers and for those comparing different CAMO
programs.

A report of an international collaborative experiment to demonstrate the uniformity obtainable using DNA profiling techniques. 总被引:2,自引:0,他引:2

This paper describes a collaborative exercise intended to demonstrate whether uniformity of DNA profile results could be achieved between different European laboratories. It was shown that this goal can be obtained provided that a common protocol is followed (specifically the use of a common electrophoretic buffer as being the most important parameter). Generally, lower molecular weight loci (with lower molecular weight fragments) such as YNH24 perform better than higher molecular weight loci such as MS43a. The results of the exercise are discussed in relation to the objectives of the European DNA profiling group (EDNAP). 相似文献

Threatening and otherwise inappropriate letters to members of the United States Congress 总被引:2,自引:0,他引:2
P E Dietz D B Matthews D A Martell T M Stewart D R Hrouda J Warren 《Journal of forensic sciences》1991,36(5):1445-1468
The authors examine the characteristics of threatening and otherwise inappropriate communications sent to members of the U.S. Congress by a sample of 86 subjects, 20 of whom threatened assassination. We quote excerpts from these letters and provide quantitative data on such variables as the volume, duration, form, and appearance of such communications; the enclosures; the subjects' perceived relationships to the recipients; the thematic content of the communications; and the messages and threats communicated. Comparisons between 43 subjects who pursued encounters with members of Congress and 43 who did not revealed 17 factors associated with such pursuit. In this population, threateners were significantly less likely to pursue an encounter than inappropriate letter writers who did not threaten, regardless of the type of threat or the harm threatened. Inappropriate letters to members of Congress are compared with those directed to Hollywood celebrities. Mentally disordered persons writing to public figures often mention and sometimes threaten public figures other than those to whom the letters are addressed, which raises important issues regarding notification of endangered third parties and the sharing of information among protective agencies. 相似文献
