ABSTRACT

Social movements confronting overlapping inequalities face the unique challenge of elucidating the heretofore invisible experiences of those whose identities lie at the intersection of existing movements. Social media platforms provide a direct outlet for intersectional social movements to make political claims visually by illuminating these complexities creatively with discursive resources such as symbols, text, and narratives. Using content analysis of images posted to the organization’s Facebook, we examine how lesbian, gay, bisexual, transgender, and queer (LGBTQ) immigration activists – as embodied by the Queer Undocumented Immigrant Project (QUIP) – attempt to communicate intersectionality online. Images posted by QUIP demonstrate how the existing ideas and values of separate established immigrant and LGBTQ movements can be reformulated and repackaged. However, the available discursive resources may compartmentalize identities, which then requires movements to generate new symbols, text, and narratives. By leveraging extant discursive resources and innovating new expressions, activists aim to communicate intersectional experiences and unite multiple struggles.  相似文献

This article examines the process of national identity formation among ethnic minorities in the Crimea – specifically, how a new common identity develops in the system of existing identities, what meaning group identities have for different minorities group and how this process influences attitudes and stereotypes toward the ingroup and outgroup. Based on surveys in the Crimea, results show that formation of a common national and regional identity leads to developing of positive stereotypes toward members of other groups, who now are involved in a new group identity, but also is connected with formation of negative attitudes and stereotypes toward other groups. The meaning of identity depends on its position in the system of identities and can be used as a criterion for early warning of conflicts.  相似文献

This paper presents a conceptually distinct analysis of the data first reported by Leather et al. Specifically, it investigates the effects of exposure to a variety of forms of work-related violence upon work attitudes and general well-being within a sample of UK public house licensees—individuals who manage public houses and hold the licence permitting the sale of alcoholic drinks on the premises. In addition, it examines the role of social support in moderating such effects. Based upon a sample of 242 licensees, it reports a consistent interaction between exposure to such violence and the availability of perceived intra-organizational support in determining the size of any negative effects upon individual well-being, job satisfaction and organizational commitment. It is argued that exposure to all forms of work-related violence, including intimidation, verbal abuse and threat, should be seen as a potential stressor within the work environment, the negative effects of which are buffered by perceived support from within the organization, but not by that perceived to be available from informal sources such as family and friends.  相似文献

组织支持、组织文化认同和情绪工作作用机制研究   总被引:1,自引:1,他引:1  
以服务行业工作人员为研究对象,通过实证分析对组织支持、组织文化认同和情绪工作间的作用机制进行研究。结果表明:同事支持、上级支持和企业支持对表层行为有显著负向影响,上级支持和企业支持对深层行为有显著正向影响;组织文化认同的行为性认同维度对表层行为有抑制作用,认知性认同、情感性认同和行为性认同则能有效激发员工的深层行为;组织支持通过组织文化认同的部分中介作用对表层行为和深层行为产生影响。  相似文献

This article introduces and discusses a new measure of the relative economic affluence (REA) between income distributions with different means. The REA measure D is applied to the U.S. white and black household income distributions of 1967 and 1979. The measure D shows that the REA of the white households with respect to the black households decreased from 1967 to 1979. This conclusion contrasts with those obtained by applications of distance or quasi-distance functions. It is shown in this study that REA measures and distance functions address different and relevant issues. An REA measure deals with the relation “more affluent than” and defines a partial strict ordering over the set of pairs of income distributions—that is, the relation is asymmetric and transitive—whereas a distance function accounts for the dissimilarity between distributions without imposing an ordering relation and hence fulfills the symmetry property.  相似文献

The relationship between the concentration ellipsoid of a random vector and its planes of support is exploited to provide a geometric derivation and interpretation of existing results for a general form of the linear regression model. In particular, the planes of support whose points of tangency to the ellipsoid are contained in the range (or column space) of the design matrix are the source of all linear unbiased minimum variance estimators. The connection between this idea and estimators based on projections is explored, as is also its use in obtaining and interpreting some existing relative efficiency results.  相似文献

Abstract

We investigate polynomial factorization as a classical analysis method for servers with semi-Markov arrival and service processes. The modeling approach is directly applicable to queueing systems and servers in production lines and telecommunication networks, where the flexibility in adaptation to autocorrelated processes is essential.

Although the method offers a compact form of the solution with favourable computation time complexity enabling to consider large state spaces and system equations of high degree, numerical stability is not guaranteed for this approach. Therefore we apply interval arithmetic in order to get verified results for the workload distributions, or otherwise to indicate that the precision of the computation has to be improved. The paper gives an overview of numerical and performance aspects of factorization in comparison to alternative methods.  相似文献

ABSTRACT

This article considers linear social interaction models under incomplete information that allow for missing outcome data due to sample selection. For model estimation, assuming that each individual forms his/her belief about the other members’ outcomes based on rational expectations, we propose a two-step series nonlinear least squares estimator. Both the consistency and asymptotic normality of the estimator are established. As an empirical illustration, we apply the proposed model and method to National Longitudinal Study of Adolescent Health (Add Health) data to examine the impacts of friendship interactions on adolescents’ academic achievements. We provide empirical evidence that the interaction effects are important determinants of grade point average and that controlling for sample selection bias has certain impacts on the estimation results. Supplementary materials for this article are available online.  相似文献
