Aggressive pursuit of free trade agreements (FTAs) and customs unions (CUs) by major and minor trading powers alike challenges
the conventional wisdom in favor of such pursuit – competitive liberalization. An equally plausible explanation for an active
bilateral and regional trade agreement policy, one which effectively de-emphasizes multilateralism, may be competitive imperialism.
The protection and enforcement of intellectual property rights is one area in which new provisions, going beyond multilateral
rules, are being negotiated and written into FTAs and CUs. Such provisions may yield insights into which characterization
of bilateralism and regionalism – competitive liberalization or competitive imperialism – is more apt.

Offender assessment and classification is becoming an increasingly important part of correctional supervision and intervention. Over the last several decades, several different methods and “generations” of offender classification have emerged. Of most value appear to be third-generation, actuarial, dynamic risk/need assessments. With any new correctional strategy, however, there is a need to investigate the use of these risk/need assessments on offender subgroups in order to inform issues, such as reliability and prevalence of criminogenic risk factors. The present study utilized data that were gathered using the Level of Service Inventory-Revised (LSI-R). Results and comparisons of these assessments were investigated and presented for Native American and non-Native American offenders as well as male and female offenders. Discussion of the results, implications, and recommendations for further research are presented. 相似文献

This paper highlights some of the central ethical challengesinvolved in undertaking social science research with refugeesin conflict and crisis situations. It focuses on two main setsof challenges: first, the difficulties of constructing an ethicalconsent process and obtaining genuinely informed consent; andsecond, taking fully into account and responding to refugeeparticipants' capacities for autonomy. The authors also discussthe challenges involved in applying the central normative principlesgoverning ethics review processes—the principles of beneficence,integrity, respect for persons, autonomy and justice—tothe context of refugee research. It is argued that researchersshould seek ways to move beyond harm minimization as a standardfor ethical research and recognize an obligation to design andconduct research projects that aim to bring about reciprocalbenefits for refugee participants and/or communities. Some ofthe methodological issues raised by this analysis are discussedin the conclusion. 相似文献

Isolation of the DNA minisatellite probe MZ 1.3 and its application to DNA 'fingerprinting' analysis 总被引:1,自引:0,他引:1

A minisatellite probe, MZ 1.3, detecting hypervariable fragment patterns was isolated from a human genomic library. A repetitive sequence of 27 bp length was identified which is contained in the probe approx. 40 times. The MZ 1.3 repeat shows variable homology of 53-73% to the repetitive sequence of the protein III gene of the bacteriophage M13 genome. Polymorphic restriction fragment patterns were found with MZ 1.3 using the enzymes Hinf I, BstN I, Hae III, Mbo I, PstI/Pvu II, and Rsa I. An average of 18 polymorphic fragments was observed using Hinf I as enzyme. The band sharing frequency after Hinf I digestion among unrelated individuals was determined to be 23.8 +/- 7.2%. An example for the application of MZ 1.3 to paternity testing in an incest case is given. The probe can be used with radioactive or non-radioactive detection systems. An approach is presented to compare polymorphic fragment patterns from individuals obtained by independent gel runs on the basis of relative band positions (RBP) and calculated in a computerized analysis. 相似文献

The Supreme Court early took note of extralegal, “social science” materials in Muller v. Oregon (1908), and a half-century later made specific reference to social science authorities in the famous footnote 11 of Brown v. Board of Education (1954). Since Brown, much has been written about the Supreme Court's use of social science research evidence, but there has been little systematic study of that use. Those writing on the subject commonly focus on areas of law such as jury size, where social science has been used, and have generally assumed that social science information has been utilized in Supreme Court decisions with increasing regularity. Surprisingly little is known, however, about either the justices' baseline use of social science authorities, or many other aspects of their uses of social science information. The focus here is on the citation of social science research evidence in a sample of 240 criminal cases decided during the 30 years between the Supreme Court's 1958 and 1987 Terms. The resulting portrait contributes to a fuller understanding of the justices' use of social science materials, and may ultimately help promote more effective utilization of social science research evidence in Supreme Court decisions. 相似文献
