Additional results for 'Sequential design approaches for bioequivalence studies with crossover designs'

In 2008, this group published a paper on approaches for two‐stage crossover bioequivalence (BE) studies that allowed for the reestimation of the second‐stage sample size based on the variance estimated from the first‐stage results. The sequential methods considered used an assumed GMR of 0.95 as part of the method for determining power and sample size. This note adds results for an assumed GMR = 0.90. Two of the methods recommended for GMR = 0.95 in the earlier paper have some unacceptable increases in Type I error rate when the GMR is changed to 0.90. If a sponsor wants to assume 0.90 for the GMR, Method D is recommended. Copyright © 2011 John Wiley & Sons, Ltd.     

Viewing Intergroup Relations in Europe through Allport's Lens Model of Prejudice

This article employs Allport's (1954) lens model of the causes of prejudice to analyze the articles in this issue of the Journal of Social Issues . The lens model specifies that historical, socio cultural, personality, and situational factors contribute to prejudice. The articles in this issue examine a number of variables at each of these levels of analysis, and many employ multilevel designs in which variables at more than one level are examined within the same study. Suggestions for future research on intergroup relations in Europe are offered including conducting more comparative and multilevel studies and creating comprehensive theories that integrate different levels of analysis. Some implications of the findings of these studies for intergroup relations programs are also discussed.     

审美·治理·自由

本文的目的不是要扩大文学的"自由效果",而是要探讨使批评、自由与文学之间的关系变得易于理解的那些历史的以及推论的条件。20世纪对康德提出的自由与文化的关系有两种完全不同的"反应":第一种将文化与工人阶级的自我解放相联系;第二种将文化刻写为治理的一种机制,它通过自我调节手段运作并使之成为可能。这两种反应紧密相连:英国成人教育与文学教育发展之间的关系史表明前者是如何紧密地仿照作为自由表达空间的后者的。要理解这两种情况,就必须考虑构成审美的原初决定性特质的无用性是如何被重新界定的,以便它能够被用作治理的工具。在文化治理中,恰恰是通过与社会隔离开来,审美文化才作为一种能够从治理上作用于它的有益手段而被提出来。审美实践被变成了可以利用的东西。正是以这种方式,审美、治理与自由在自由治理的诸种机制之内刻写了某种特有的张力。     

A review of generalization methods used in empirical social work literature

This article reviews methods currently used for generalization of findings, based on a review of a representative sample of empirical research studies drawn from three major social work research journals: Social Work Research , Journal of Social Service Research , and Research on Social Work Practice , over a 10-year period (1996–2005). Findings revealed a greater discussion of generalizability limitations in comparison with the past, and other types of generalization methods such as conceptual generalizations and qualitative comparisons of study results with those of other studies. Relatively low usage of quantitative comparisons of sample to population and replication procedures was detected. Implications of these trends are discussed and approaches for improvements are explored.

Class and gender inequalities in different types of welfare states: the Social Citizenship Indicator Program (SCIP)

Korpi W. Class and gender inequalities in different types of welfare states: the Social Citizenship Indicator Program (SCIP) Int J Soc Welfare 2010: ??: ??–??© 2010 The Author(s), Journal compilation © 2010 Blackwell Publishing Ltd and International Journal of Social Welfare. This article considers the role of legislated welfare state institutions as mediators of effects of political and structural forces on citizens' levels of living of relevance to inequalities in health and mortality. The focus is on institutional structures of welfare state programmes relevant to class inequality, as indicated by income inequalities, and to gender inequality, conceived of as differences in agency. I introduce the Social Citizenship Indicator Program, a database providing quantitative and qualitative information on structures of main social insurance programmes in 18 countries from 1930 to 2000, on about 300,000 data points. It is used to delineate types of distributive institutions of relevance for income inequality. Institutions relevant for gendered agency inequality affect choices by women, especially mothers, between unpaid and paid work. Driving forces behind the emergence of differences in distributive institutions are discussed, and patterns of class and gender inequalities are outlined.

Introduction to Improving Arab-Jewish Relations in Israel: Theory and Practice in Coexistence Educational Programs

Israeli Jewish and Arab experts within Israel have developed innovative intergroup relations programs, educational efforts designed to improve relations between Israeli Jews and Israeli Arabs. Social scientists, educators, and practitioners on both sides of the Arab-Jewish conflict have dedicated themselves to lessening the hostility between these two groups within Israel through coexistence educational training. This issue presents theory, methods, and data from these coexistence educational programs. The introductory article presents a brief history of this conflict; the groups' differing perceptions regarding the dispute; some information about the role of culture, socioeconomic status, and ethnicity in the discord; and some of the social psychological processes that perpetuate and recreate the hostilities. Last, it provides a brief preface of this issue's articles.
