This article presents a biographical overview of Minseok Ahn’s career, specifically highlighting his role as a public sport sociologist. Notably, Ahn has spent time as a student activist, worked as a physical education teacher, served as a scholar with a university appointment, and held office in the South Korean National Assembly. Throughout his career, he has sought engagement with multiple publics in multiple ways to pursue reform in sport and physical education. An examination of Ahn’s career can offer insights regarding the processes and challenges involved in pursuing public sociology and provide a cross-national perspective that helps us consider the possibilities that exist for scholars to seek progressive change in sport through public engagement.  相似文献

Studies of elites and elite education have largely not involved rigorous debate, either with regard to the conceptual resources deployed or methodologies adopted. Even the concepts elite and elite schools have not been problematized much. Further, there is a tendency for people to cite, rather than engage or dispute each other. So while the number of published studies increases and the field grows in size, and expands in focus, it is not necessarily growing through spirited dialog and critique. The first part of this paper considers the ways in which the methodological scope in the study of elites and elite education has been restrained and limited through the repetition of particular methodological frameworks and practices. Drawing on the work included in this special issue and other recent research, we then suggest some methodological possibilities for expanding this scope. In the second main part, we offer some provocations about the theoretical resources that are conventionally deployed. We argue that scholars need to be much more critically self-conscious about their uses of elite theories and class theories and much more aware of the ideological implications of their research.  相似文献

In vitro assays of platelet function and coagulation are typically performed in the presence of an anticoagulant. The divalent cation chelator sodium citrate is among the most common because its effect on coagulation is reversible upon reintroduction of divalent cations. Adding divalent cations into citrated blood by batch mixing leads to platelet activation and initiation of coagulation after several minutes, thus limiting the time blood can be used before spontaneously clotting. In this work, we describe a herringbone microfluidic mixer to continuously introduce divalent cations into citrated blood. The mixing ratio, defined as the ratio of the volumetric flow rates of citrated blood and recalcification buffer, can be adjusted by changing the relative inlet pressures of these two solutions. This feature is useful in whole blood assays in order to account for differences in hematocrit, and thus viscosity. The recalcification process in the herringbone mixer does not activate platelets. The advantage of this continuous mixing approach is demonstrated in microfluidic vascular injury model in which platelets and fibrin accumulate on a collagen-tissue factor surface under flow. Continuous recalcification with the herringbone mixer allowed for flow assay times of up to 30 min, more than three times longer than the time achieved by batch recalcification. This continuous mixer allows for measurements of thrombus formation, remodeling, and fibrinolysis in vitro over time scales that are relevant to these physiological processes.  相似文献

This article examines the recent move by many television sports broadcasters of streaming their content online behind geographically restricted “geofences.” Despite the increasing use of this distribution method, we argue that Internet users are increasingly bypassing geofences that center sports consumption within a nationalized television broadcasting framework through the use of VPN (virtual private network) technologies. Importantly, the geographic fluidity of the Internet often allows users to do this legally—producing meaningful ruptures in the logic that seeks to replicate the structures of mediation central to the television broadcast model within the space of the Internet. We argue that the streaming of sports content, then, should be understood and analyzed as an enforcement of corporate media strategies and reflection of telecommunication policy, as well as a cultural practice and tactic. Large transnational media corporations, typically the holders of popular sporting rights, attempt to bend digital sports content consumption to the broadcast models that they have historically employed. Yet, amidst this emerging model of digital broadcasting lie the problems of digital geography and the cultural practice of a streaming culture within the conditions of post-convergence. This practice often rejects the restrictions and stipulations of digital broadcasting in favor of a globetrotting, station-hopping exercise of content hunting.  相似文献
