The study of research utilization and administration has been a growing field, but the emphasis in this field has been on industrialized countries. This article presents the results of a pioneering study of the use of research by senior officials in the Nigerian Federal Government. The article focuses first on Federal Government-sponsored research, it reviews how such research was initiated and conducted, how results were presented and what affected the use of the results. The article then describes expatriate-sponsored research, casts light on the conventional assumption about the amount of such research and points to the fact that there was comparatively less awareness of the results. The article not only provides significant information about the administration of research in Nigeria but emphasizes the need to give attention to this aspect of administration. 相似文献

The ultimatum game is a standard instrument for laboratory experimentalists.It has been replicated in a large number of environments andpoints to special considerations for fairness. Although it hasbeen popular in the experimental community, researchers havenot harnessed all the statistical power they should to evaluatethe dynamics at work in this type of a bargaining game. Thisresearch uses two planned treatments, the first involving asignaling condition concerning a subject's "type," and the seconda price effect built into the structure of the game. We findthat there are no significant main effects as a result of thesignaling condition of a subject's type, but that there arestrong effects as a result of the different payoff parameters.Using a variety of multivariate models we find important, nonobviousinteractions with the gender of the subjects. The lesson thatwe take away from this research is that experimentalists canlearn more from data collected in the tightly controlled laboratoryenvironment by using statistical techniques that complementtheir research designs. 相似文献

The purpose of these studies was to evaluate the performance characteristics of the Cozart Microplate Enzyme Immunoassay (EIA) for the determination of methadone in oral fluid from patients in a drug misuse treatment program. Oral fluid specimens were collected using the Cozart RapiScan Collection system from 198 donors who were receiving treatment for their addiction and were monitored for drug misuse. Oral fluid specimens were also collected from forty volunteer donors who were not drug users. The specimens were analyzed in the laboratory by EIA and then analysed for methadone and its main metabolite EDDP by gas chromatography-mass spectrometry (GC-MS). A total of 103 samples were confirmed positive for methadone. The Cozart Microplate EIA for d-Methadone in oral fluid using a cutoff of 30 ng/mL in diluted oral fluid had a sensitivity of 91.3% +/- 2.8% and a specificity of 100% +/- 1.0% vs. GC-MS. 相似文献

Bird conservation agencies and organizations can take credit for a long list of transnational policy accomplishments. This
article examines one set, a constellation of arrangements developed over the past three decades by those seeking to conserve
western hemisphere shorebirds. At the center of this constellation are the US and Canadian national shorebird conservation
plans and a cross-border initiative, the Western Hemisphere Shorebird Conservation Reserve Network. We treat these and associated
plans, programs, and initiatives as a nested set of institutions, noting that these are operated by a wide assortment of state
and societal actors. Exploring the potential of a framework based on Oran Young’s concept of interplay, we analyze the construction
of these institutions and efforts to establish effectiveness. Examining activity in three zones of issue proximity, we conclude
that shorebird conservationists have responded well to formative interplay challenges. They have made least progress in engaging
remote institutions responsible for threats to shorebird habitat. We note, though, that it is important to distinguish between
scientific and political levels of interplay work. On a substantive level we conclude that the shorebird community is well-positioned
to move beyond generative and programmatic tasks to focus on establishing policy capability. On a theoretical level, we conclude
that a framework based on interplay provides a strong foundation for analysis of the forces shaping the effectiveness of informal
conservation institutions such as the ones examined.
