This article describes a generic model for access to samples and information in human genetic databases. The model utilises a "GeneTrustee", a third-party intermediary independent of the subjects and of the investigators or database custodians. The GeneTrustee model has been implemented successfully in various community genetics screening programs and has facilitated research access to genetic databases while protecting the privacy and confidentiality of research subjects. The GeneTrustee model could also be applied to various types of non-conventional genetic databases, including neonatal screening Guthrie card collections, and to forensic DNA samples. 相似文献

This paper investigates the Immigration and Naturalization Service (INS) interior and border enforcement effort allocation choice following the enactment of IRCA in 1986. The INS increasingly allocated a disproportionate amount of resources along the border as a result of the new law. It is contended that this behavior is consistent with that of a public agency intent on maximizing its budget and not in accord with minimizing the undocumented population in the United States. The theory developed here is then used to evaluate proposals that could potentially reconcile the INS's objectives with those of the policy makers and the public. 相似文献

This paper attempts to test the degree of responsiveness of Canadian provincial governments to different political groups in establishing their relative minimum wage policies over the 1975–1982 period. It discusses alternative explanations of minimum wage policies and focuses on the political market approach, where women, youth, small business and unions play a role. An econometric model is specified and estimated on pooled annual time series and cross-section data for nine provinces in Canada. The results tend to support most of the hypotheses. 相似文献

Techniques of governance in the Hashemite Kingdom of Jordan do not follow a single or unifying logic. Despite a more than decade-long shift towards a neoliberal orientation, market-disciplinary policies coincide with important exceptions. This article employs a modified variegated neoliberalization approach to explore one such exception. Specifically, it analyses the recent debate over the country’s bread subsidy to elucidate key elements of Jordan’s socio-economic transformation. The persistence of this long-standing welfare programme is linked to the uneven pathways of Jordanian neoliberalization and two potent political rationalities imbricated in this process. 相似文献

In an effort to improve laboratories performing hair analysis in forensic cases, the French Society of Analytical Toxicology (S.F.T.A.) has implemented a proficiency testing program since 1992. Actually about 10 laboratories are participating. Each survey is dedicated to one analyte or one pharmacological class: opiates (6-monoacetylmorphine, morphine and codeine), cocaine and benzoylecgonine, tetrahydrocannabinol, buprenorphine and norbuprenorphine, beta-blockers (metoprolol, atenolol), beta 2-agonists (salbutamol, clenbuterol). Animal hair was tested for clenbuterol. Prior to sending, hair samples were reduced to a powdered form, well mixed to ensure homogeneity, and then tested by GC/MS or HPLC/MS. Results confirm those obtained in a preliminary study on opiates and cocaine analysis in hair: a common analytical procedure has to be used by all the participants, including hydrolysis of hair. It is essential to work on authentic drug-positive hair samples and not on spiked samples. Participation at this program is free of charge and considered as an educational tool. Comparison of the results with those of other laboratories in Europe and USA shows that the analytical methods used during this program are in accordance with all the other procedures. 相似文献

This study seeks to expand our understanding of how the media increase the level of political information, by focusing on an understudied yet important learning outcome: knowledge of the political past. The article explores the factors underlying variation in the recognition of the leading actors in the transitional process in Portugal. The results show that television news and newspaper exposure foster recognition of these actors, but that media use interacts with personal experience of the transition (stronger effects among younger cohorts) and party identification (stronger impact on those who do not feel close to a political party). 相似文献
