Relatively little attention has been paid to the use and importance of labels used by men who have sex with men to describe insertive or receptive sexual behavior during intercourse. This study examines sexual self‐labels, sexual behavior, HIV transmission risk, and psychological functioning among 205 HIV‐seropositive men who have sex with men. The majority of participants (88%) identified as a “top, “ a “bottom, “ or “versatile. “ Tops were more likely to engage in insertive anal intercourse than bottoms, and bottoms were more likely to engage in receptive anal intercourse than tops, with versatiles reporting intermediate rates of both behaviors. Although the results suggest preliminary evidence regarding the predictive utility of self‐labels, sexual behaviors of self‐label groups were greatly overlapping. Differences were found among self‐label groups in gay self‐identification, internalized homophobia, sexual sensation seeking, and anxiety. Results suggest an added value in assessing self‐labels in addition to asking about sexual behavior. 相似文献

This paper gives necessary and sufficient conditions for a mixed regression estimator to be superior to another mixed estimator. The comparisons are based on the mean square error matrices of the estimators. Both estimators are allowed to be biased. 相似文献

We critically examine the accepted notion that primary education is a legitimate and necessary function of the state. The
notion is based upon three tenets: 1) public education is a necessary condition for democracy, 2) the market will not provide
equal access and quality of education to all, and 3) education represents an external economy. Each tenet is addressed and
evaluated according to its merits. In doing so, we also contrast the fulfillment of the ends implicit in the tenets under
state and market provisions. We conclude that the state provision of primary education cannot be justified by these goals,
and that market provision is a preferable alternative.

The idea of standardizing concepts in sociology is not new, but we have made little progress, despite the early hopes of such
theorists as Durkheim and Weber. This article refutes the arguments of some who contend that we do not need standard concepts,
we cannot make standard concepts, social phenomena are too complex and changeful, sociologists are too individualistic and
sociological concepts are too context-dependent. The author proposes that the American Sociological Association appoint a
Committee on Basic Sociological Concepts to investigate and recommend the official adoption of a basic conceptual language
in American sociology.
This paper is excerpted from a longer discussion first presented to a session on metatheory at the 1990 meetings of the American
Sociological Association, and forthcoming in a collection of papers from that session. 相似文献

Dynamic Measures of Individual Deprivation 总被引:1,自引:0,他引:1
We introduce a one-parameter class of individual deprivation measures. Motivated by a suggestion of Runciman, we modify Yitzhaki’s index by multiplying it by a function that is interpreted as measuring the part of deprivation generated by an agent’s observation that others in his reference group move on to a higher level of income than himself. The parameter reflects the relative weight given to these dynamic considerations, and the standard Yitzhaki index is obtained as a special case. In addition, we characterize more general classes of measures that pay attention to this important dynamic aspect of deprivation. 相似文献

The aim of this study was to compare the mental health, substance use, and sexual risk behaviors of rural and non-rural transgender persons. Online banner advertisements were used to recruit 1,229 self-identified rural and non-rural transgender adults (18+ years) residing in the United States. Primary findings include significant differences in mental health between rural and non-rural transmen; relatively low levels of binge drinking across groups, although high levels of marijuana use; and high levels of unprotected sex among transwomen. The results confirm that mental and physical health services for transgender persons residing in rural areas are urgently needed. 相似文献

Walter G. Stephan 《The Journal of social issues》2006,62(3):597-605
Editors' introduction: Walter Stephan's interest in intergroup relations grew from his early involvement in intercultural relations. He spent substantial time in Latin America as well as Vietnam during his college years. These experiences influenced his choice to study social psychology at the University of Minnesota. His first foray into intergroup relations came with his move to Austin, Texas, in 1971. A Court mandate ordered schools to be desegregated, and Stephan examined the effects of school desegregation there on students' self-esteem and intergroup attitudes. His field research on the effects of desegregation as well as classroom interventions to improve intergroup relations was complemented by his laboratory research on intergroup biases, intergroup threat, intergroup anxiety, and empathy. Stephan brings this lifetime of involvement in both basic and applied research, and deep concern for effective practice and humanistic philosophy, to his commentary. He opens the commentaries with an elucidation of the difficulties in, and benefits of, the central thrust of this volume: the researcher-practitioner collaboration. He paints portraits of practitioners, researchers, and practitioner-researchers, and classifies articles in this issue accordingly. He notes the difficulties among the various parties interested in improving intergroup relations, spanning from simple lack of knowledge to lack of contact to lack of meaningful ways to interact. However, potential benefits of collaboration are abundant for all parties, and Stephan proposes a number of ways in which such partnerships could be actualized. 相似文献
