Objectives. Harris and Sim (2002) recently demonstrated the complexity of lived race by exploring patterns of racial self‐identification. They raised important sociological questions about the role of context in racial self‐identification, but offered an incomplete picture of ethnic fluidity by excluding Hispanics from their analyses. We address this limitation with data on Hispanics from the National Longitudinal Study of Adolescent Health (Add Health). Methods. Our social‐psychological approach, using compositional analysis, focuses on the lived experience of race and ethnicity as qualitatively similar conceptual categories. Results. Informed by the cognitive process of social categorization, we find that considerably more individuals show fluidity in racial and ethnic self‐identification across contexts than suggested by Harris and Sim. Conclusions. Harris and Sim's thesis is even more strongly supported by these findings than in their original analysis, and our findings reinforce their challenge to the assumed stability of racial and ethnic measurement in sociology. We conclude by proposing a change in the measurement of race/ethnicity in America.  相似文献

In a majority rule voting game, the uncovered set is the set of alternatives each of which can defeat every other alternative in the space either directly or indirectly at one remove. Research has suggested that outcomes under most reasonable agenda processes (both sincere and sophisticated) will be confined to the uncovered set. Most research on the uncovered set has been done in the context of voting games with a finite number of alternatives and relatively little is known about the properties of the uncovered set in spatial voting games.We examine the geometry of the uncovered set in spatial voting games and the geometry of two important subsets of the uncovered set, the Banks set and the Schattschneider set. In particular, we find both general upper and lower limits on the size of the uncovered set, and we give the exact bounds of the uncovered set for situations with three voters. For situations with three voters, we show that the Banks set is identical to the uncovered set.  相似文献

ABSTRACT

In this paper, we explore what we call the “dermatologization of life” and how it regulates the ways in which acne sufferers relate to their skin. We refer to these ways of relating to the skin as “skin sensing”. Through an analysis of the online narratives found on the website acne.org, we demonstrate how the skin sensing bound up with dermatologization both converges with and diverges from biomedical understandings of acne in three key contexts: the hormonal, the alimentary and the nocturnal. In doing so, we show that skin sensing involves a complex combination of pleasure and pain, excitement and exhaustion, and work and play. Ultimately, we suggest that the ways in which acne sufferers sense their skin open up a set of possibilities that not only disable but also enable them as they embark on the often all-consuming quest for a clear complexion.  相似文献

Compared to job‐specific conditions, the interpersonal context of work has received less attention from work–family scholars. Using data from a 2007 U.S. survey of workers (N = 1,286), we examine the impact of workplace social support and interpersonal conflict on work–family conflict and exposure to boundary‐spanning demands—as indexed by the frequency that workers receive work‐related contact outside of normal work hours. Findings indicate that workplace social support is associated negatively with work‐to‐family conflict, while interpersonal conflict at work is associated with higher levels of work‐to‐family conflict. Results also indicate that both supportive and conflictive work contexts are associated with more frequent exposure to boundary‐spanning demands. However, workers in supportive contexts are more likely to appraise these demands as beneficial for accomplishing work tasks, and are less likely to appraise them as disruptive to family roles. By contrast, workers in conflictive contexts are more likely to appraise demands as disruptive to family roles, and are less likely to appraise them as beneficial for paid work. Consequently, our findings underscore the resource and demands aspects of interpersonal work contexts and their implications for the work–family interface.  相似文献

Concerns about failed and fragile states have put state‐ and nation‐building firmly on the academic and policy agenda, but the crucial role of public services in this process has remained underexplored. The 1960s and ‘70s generated a substantial set of literature that is largely missing from current writing. It identified state penetration, standardisation and accommodation as key processes in the state‐ and nation‐building sequence. This article analyses these three processes in Western Europe in the seventeenth to nineteenth centuries, and the role of public services therein, to explore how they may help us to understand the success and failure of state‐ and nation‐building in developing countries and fragile states.  相似文献

All adoptions, including those facilitated by public agencies, should be evaluated for openness. Although there are no national figures related to openness in public welfare, there are indications that it is not considered in all cases. Adoption myths may be one of the reasons that adoption workers do not always assess a family's ability to maintain a more open adoption arrangement. The following study is the initial validation of a multidimensional psychometric instrument developed to measure myths as they relate to open adoption. Based on a sample of 547 university students, the results indicate very good reliability and acceptable factorial and construct validity. The instrument was designed as a training and research tool to inform child welfare personnel and policy makers of the influence of adoption-related myths on child welfare adoption practice.  相似文献

This article seeks to identify factors associated with the formation and development of nonmetropolitan destinations for older in‐migration, thereby explaining why some U.S. counties are more likely than others to be nonmetro retirement destinations. We contend that most nonmetro retirement destinations are established and developed over time through a path‐dependent process. When amenities are commodified as recreation and tourism, migration streams tend to be established that ultimately produce sustained in‐migration of older persons to selected destination communities. We use data from a variety of official sources and a spatial statistics methodology to examine intercounty variability in net migration rates at ages 60–74. Our findings are consistent with the aforementioned path‐dependent development framework. Counties with a long history of population growth, previous experience attracting older in‐migrants, attractive natural amenities, and a developed recreation and tourism industry are those most likely to be retirement‐age migration destinations. In contrast, agricultural heartland and relatively large population size are associated with lower rates of older in‐migration. Older in‐migration should be seen as neither a panacea for strapped rural communities nor a “pensions and care issue.” Older migrants can be “gray gold,” but they can also pose challenges, such as possibly increased demand for public services as they age in place.  相似文献

This article describes estimation and inference procedures for the parameters of the Box-Cox and foided-power transformations in repeated measures and growth curve models. Procedures for computing maximum likelihood estimates of the transformation and covariance parameters under several covanance structures (omnibus sphericity, local sphericity, and unstructured) are described. Lack of fit statistics and hypothesis tests for comparing these structures also are described. The procedures are illustrated on three data sets. Software for performing the analyses in the SAS System is described and is available from the authors.  相似文献

In the face of administrative and pedagogic changes in professional social work training, educators and trainers face considerable uncertainty. Key dilemmas concern what is meant by competence, and how far it is possible to identify and reconcile technical and ideological competencies. This paper uses empirical material from a semi-participant study to explore the relevance of the concept ‘cloak of competence’, with reference to the behaviour of tutors and practice teachers. It suggests that excessive or continuous uncertainty generates avoidance or coping strategies, which lead to a resolution by the achievement of an appearance of competence. The consequences of these processes for staff development are then briefly considered.  相似文献
