Some new factor screening designs using the search linear model

Factor screening designs for searching two and three effective factors using the search linear model are discussed. The construction of such factor screening designs involved finding a fraction with small number of treatments of a 2^m factorial experiment having the property P_2t (no 2t columns are linearly dependent) for t=2 and 3. A ‘Packing Problem’ is introduced in this connection. A complete solution of the problem in one case and partial solutions for the other cases are presented. Many practically useful new designs are listed.     

Perspectives on Corporate Control: Implications for CEO Compensation

This study examines the influence on CEO paypractices of four corporate control perspectives:managerial control, class hegemony, external control,and efficient market. The results indicate the influence of both market and extra-market controls on thedetermination of CEO pay levels and criteria.Implications for the governance of firms and the studyof corporate control are drawn.     

Identity Development in a Transracial Environment: Racial/Ethnic Minority Adoptees in Minnesota

It has been argued that transracially adopted children have increased risk of problems related to self-esteem and ethnic identity development. We evaluated this hypothesis across four groups of transracial adoptees: Asian (n = 427), Latino (n = 28), Black (n = 6), mixed/other (n = 20), and same-race White adoptees (n = 126) from 357 adoptive families. No mean differences were found in adoptees’ ratings of affect about adoption or of curiosity about birth parents. Some differences were found in general identity development and adjustment. There were notable differences in communication about race/ethnicity across groups and between parent and child report.     

Social Responsibility,Substance Use,and Sexual Risk Behavior in Men Who Have Sex With Men

Considerable public health literature focuses on relationships between problematic human characteristics (e.g., psychopathology) and unhealthy behaviors. A recent movement termed positive psychology emphasizes the advantages of assessing relationships between human strengths (e.g., altruism) and beneficial health behaviors. The present study assessed social responsibility, an orientation to help or protect others even when there is nothing to be gained as an individual, and its relationship to HIV-relevant behaviors. In our sample of 350 men who have sex with men (MSM), social responsibility was negatively correlated with substance use and HIV risk behaviors. Men who had been tested for HIV and knew their HIV status—a behavior that helps men protect their partners but does not protect themselves from the virus—also scored higher in social responsibility. Interventions designed to reduce HIV risk behavior in MSM may benefit from efforts to promote human strengths.     

Joint Beliefs in Conflictual Coordination Games

The traditional solution concept for noncooperative game theory is the Nash equilibrium, which contains an implicit assumption that players probability distributions satisfy t probabilistic independence. However, in games with more than two players, relaxing this assumption results in a more general equilibrium concept based on joint beliefs (Vanderschraaf, 1995). This article explores the implications of this joint-beliefs equilibrium concept for two kinds of conflictual coordination games: crisis bargaining and public goods provision. We find that, using updating consistent with Bayes rule, players beliefs converge to equilibria in joint beliefs which do not satisfy probabilistic independence. In addition, joint beliefs greatly expand the set of mixed equilibria. On the face of it, allowing for joint beliefs might be expected to increase the prospects for coordination. However, we show that if players use joint beliefs, which may be more likely as the number of players increases, then the prospects for coordination in these games declines vis-à-vis independent beliefs.     

Cultural Sociology and Other Disciplines: Interdisciplinarity in the Cultural Sciences

The subject of this article is the relationship between cultural sociology and approaches to culture in other social science disciplines. What are the characteristics of the theoretical environment, in which cultural sociology is operating? The article begins by reviewing the literature on interdisciplinarity. Many authors argue that interdisciplinarity is increasing or should be increasing, but the general consensus is that disciplinary isolation is the norm. From this perspective, the relationships between disciplines can be understood in terms of trading zones, in which fields in different disciplines have little in common, theoretically, or empirically. Interdisciplinary communication in ‘trading zones’ requires that participants laboriously construct a set of terms that permits them to exchange ideas. Alternatively, I propose that clusters of fields in different disciplines are linked by free-floating paradigms. Participants in disciplines that share ‘free-floating paradigms’ are able to communicate with one another more readily. The article presents evidence for the second interpretation, drawn from survey articles in disciplinary handbooks. Disciplines and fields in which the study of culture draws from the same pool of paradigms and models and shares a set of lines of inquiry with cultural sociology include traditional disciplines, such as anthropology, communication, geography, history and psychology, and interdisciplinary fields, such as cultural studies, communication, feminist theory, material culture, science studies, and visual culture. Interdisciplinary fields – particularly cultural studies – perform an important role in diffusing paradigms across disciplinary boundaries. Free-floating paradigms are associated with the work of major theorists, such as Lévi-Strauss, Barthes, Foucault, Bourdieu, Lyotard, Baudrillard, Clifford Geertz, Bruno Latour, Adorno, Gramsci, and Habermas.
