The CPMP Points to Consider on Adjustment for Baseline Covariates recently came into operation. As well as providing sound guidance, this document states a strong position against dynamic allocation. This paper reviews the most important issues involved and aims to stimulate interest in further investigating alternative allocation methods in clinical trials.

This article focuses on research on international labor migration in Asia, a region marked by intense migration in the last four decades. The review covers migration research undertaken from the post-1970s to the present. The growing significance of international migration in the region has stimulated the production of evidence-based knowledge on Asian migration in Asia. This is indicated by the growing literature on migration-related questions, the development of research centers focused on migration, and the development of research networks in the region. Although migration research is thriving, future efforts should aim toward theory building and establishing the links between internal and international migration.  相似文献

The notion of isomorphism has been recommended as a comceptual framework to guide the practice of marrige and family therapy (MFT) supervision. The term is frequently cited in the MFT training literature but is often used in different ways. A panel of MFT supervirors rated the impotance and relevance to both therapy and supervision of a large pool of variables. The majority of variables were found to be a equally relevant or isomorphic to the domains of MFT and MFT supervisoin. A qualitative interview with a small subset of the panelists suggested that the concept, to varying degrees, has influenced their work as supervisors. The implications of the results for theory development, research, and supervisory practices are discussed.  相似文献

College students (N = 276) completed surveys describing two common drinking situations. One scenario described a student alone in an apartment after a weekday class; the other, the same student at a weekend party. Sex of the drinker in the scenario was systematically varied. Students estimated the number of drinks a social drinker and a problem drinker would have in each situation. Results indicated that: 1) definitions of social and problem drinking are strongly influenced by drinking context, and 2) male and female subjects estimated that problem drinkers of the opposite sex drank more than problem drinkers of their own sex. Problem drinkers were regularly estimated to consume three to four more drinks than the subject would in the same situation. Implications for education and prevention are discussed.  相似文献
