Recent sociological analyses of the intersections of race and science recognise race’s quality as an enacted object. Through this analytic lens, race is always materialising in the practices and processes that enrol it and therefore enjoys a kind of multiplicity. The context of blood stem cell transplantation, a scientific domain marked by a more and less explicitly racialised logic, offers an opportunity to see the conceptual assertion of race’s multiplicity play out. Indeed, an exploration of the UK’s stem cell inventory reveals—through analysis of interviews, policy and parliamentary meetings—how race materialises in the various practices that comprise this increasingly popular cancer treatment option. Looking at practices of recruitment, inventory management and tissue selection in particular provides an interesting window to look upon race and the many signifiers that implicate it. These cases reveal moments of race’s stablisation and silencing; its oscillation between the status of vital information to the life of a public stem cell inventory, and of secondary data that provides little useful information to clinicians selecting tissue. Adopting an analytic lens that attends to race’s multiple enactments allows us to begin asking why enactments take the shape they do, and why the particular practices that mobilise them come to be. 相似文献

Force and Freedom insists that, ‘Freedom, understood as independence of another person's choice, is [all] that matters’. In this paper I suggest that this premise leads Ripstein to an instrumentalization of democracy that neglects a properly public and collective notion of freedom. The paper first criticizes Ripstein's key argument against any extension of public purposes beyond the upholding of persons’ ‘independence of others’ choice’. More constructively, the paper then suggests that a space of public freedom is opened up when people deliberate in order to form and pursue democratic purposes. Citizens may act together to promote ends that they think are worthwhile, without dominating one another or restricting individual freedom. 相似文献

Problems with social anxiety are frequently reported in people with autism spectrum disorders (ASD). It is possible that social anxiety, when present, exacerbates the experience of hostility and other forms of aggression in relation to ASD symptoms. This study sought to determine if social anxiety symptoms mediate the relationship between features of ASD and feelings of hostility in young adults. Self-report measures of social anxiety, ASD, and facets of aggression were collected in a non-clinical sample (n = 618) of college students. Social anxiety was found to partially mediate the relationship between ASD features and self-reported hostility. There was also evidence for inconsistent mediation, such that social anxiety dampened the strength of the relationship between ASD symptoms and verbal and physical aggression. Findings highlight the potential influence of associated psychiatric symptoms in people with ASD. In addition, dimensional conceptualization of ASD symptoms, as opposed to a categorical approach solely, may be a useful approach to studying complex personality processes. 相似文献

This review of the literature examines the effect of contextual variables (i.e., characteristics of the perpetrator and victims, observer characteristics) on perceptions of physical and psychological aggression in close relationships. Observers view physical aggression as more serious, harmful, abusive, and more deserving of punishment than psychological aggression, male aggression as more serious than female aggression, and aggression in committed, exclusive relationships as more serious than aggression in casual ones. Victims of psychological aggression, however, perceive it as more harmful than physical aggression and consider the effects to be longer-lasting. The disparity between observer and victim perceptions of physical and psychological aggression extends to mental health professionals, who tend to judge the severity of aggressive behaviors based on frequency and duration of the actions instead of perpetrator intent. This difference of opinion may influence the reporting of and intervention in physically or psychologically aggressive situations, and how these types of aggression are treated by legal professionals, especially if those legal professionals are informed about aggressive romantic relationships by third-party observers whose opinions of the situation differ from those of the victims. 相似文献

The Go/No Go Association Task (GNAT; Nosek & Banaji, 2001) is an implicit measure with broad application in social psychology. It has several conceptual strengths to recommend it over other implicit methods, but the belief that it has poor reliability coupled with the absence of a method for calculating this important psychometric property has hindered its wider acceptance and use. Using data obtained from six GNAT studies covering a wide range of content areas, Study 1 compares the properties of different methods for estimating reliability of the GNAT. Study 2 demonstrates a resampling procedure to investigate how reliability varies as a function of block length. Study 1 shows that with appropriately chosen stimuli the GNAT can be a very reliable measure, while Study 2 indicates that as an empirical rule of thumb 50 to 80 trials per block should yield adequate to very good reliability. However, researchers are urged to calculate their own reliability coefficients, to this end we discuss GNAT design issues and provide procedures for calculating GNAT reliability which we hope will enhance the utility of the GNAT as a measure and promote its use in studying implicit cognition. 相似文献

Three studies show that people whose physical features are seen as more (versus less) racially stereotypical are more vulnerable to social rejection and exclusion from those outside their group. In Study 1, which used an online social networking site, Blacks perceived as more physically stereotypical were found to have fewer non-Black friends, compared to less-stereotypical Blacks. In Study 2, which used an experimental paradigm, requests for friendship made to non-Blacks by more-stereotypical Blacks were more likely to be rejected than those made by less-stereotypical Blacks. Finally, in a college dormitory, people judged to have more (vs. less) racially stereotypical physical features were found to interact less often with outgroup members. This work substantiates a growing body of research demonstrating that people who are perceived as more physically stereotypical of their racial group are particularly vulnerable to discriminatory treatment by outgroup members across a variety of life domains. 相似文献
