This article analyses the real cause of the tragedy of Othello. From the perspective of his social status, the article points out that the implication of his collapse into murderous violence is actually his constant worries about the threats to his social identity as a black hero in a white world. 相似文献

This essay is intended to explore some of the elements which bring about the tragic destiny of the heroine, Eustacia. She is a beautiful and romantic woman with violent passions. In her dark beauty, Hardy has painted one of his most memorable portraits. This essay attempts to deal with the topic question primarily from two aspects, the inner world of Eustacia herself and the external world around her. In Hardy＇ s work, human existence is usually depicted as a tragedy determined by powers beyond the individual＇ s command the external pressures of society and the internal compulsions of character. 相似文献

Social media (SM) are fast becoming a locus of disaster-related activities that range from volunteers helping locate disaster victims to actions that are malicious and offensive, from sincere expressions of empathy towards affected communities to consuming disaster imagery for mere entertainment, from recovery support funds being collected to online marketers preying on the attention afforded to a disaster event. Because of the diversity and sheer volume of both relevant and irrelevant information circulating throughout SM, prioritising an affected population’s needs and relevant data is an increasingly complex task. In addition, SM data need to be interpreted as manifestations of social processes related to community resilience, diversity and conflict of interests, and attitudes to particular response strategies. The use of SM in disasters generates a growing need for domain-specific technological solutions that can enhance public interests as well as address the needs of both disaster managers and the affected population. This task requires integrating social sciences into the development of tools that enable disaster SM data detection, filtering, analysis and representation. The aim of this paper is to contribute to a critical-constructive dialogue between social scientists and developers of SM analytic capabilities. In the context of historical, anthropological and sociological research on disaster, this paper outlines concepts of the disaster paradigm, data as a product of social and representational practices, and disaster context, and discusses their heuristic significance for the analysis of disaster SM as a manifestation of social and cultural practices. 相似文献

This essay examines different approaches to writing the history of science in light of the increased importance of microhistorical studies in the past two decades. It specifically examines the role of microhistory within the history of science and the importance of Thomas Kuhn's concept of the "normal exception" in early methodological statements about the function of microhistory. It also considers the possibilities for writing archivally based history of science for a general readership as a means of bridging the divide between specialized research within the subfields of the history of science and more general accounts of the nature and growth of science. 相似文献

Standards Development Organizations (SDO) make critical decisions shaping the direction of technological innovation. SDOs are usually considered to offer a neutral venue for the collaborative efforts of different stakeholders, which often pursue competing particular interests. Nevertheless, individuals acting on behalf of the SDO, such as working group chairs, are themselves often employees of individual SDO stakeholders. Recently, there have been concerns that over-representation of the employees of certain powerful stakeholders in SDO leadership positions may undermine the objectivity of SDO decision making. Nevertheless, to date, there exists no empirical evidence to corroborate these concerns. We find that being affiliated with one of the largest SDO stakeholders significantly increases an individual’s likelihood of being appointed to a leadership position at IETF, but not at 3GPP. At the same time, in both SDOs, working groups whose chairs are affiliated with leading stakeholders produce standards that are less cited and less referenced than standards produced by other working groups, in particular those chaired by university affiliates. Our findings suggest that the commercial interests of individuals’ employers may facilitate these individuals’ ascension to SDO leadership positions, but the potential for conflicts between these commercial interests of chairs’ employers and the organizational goals of the SDO may negatively impact the success of the working group’s standards. 相似文献

As technical standards are an important part of China's industrial transformation towards an innovation-driven economy, Chinese organizations have started to deploy substantial resources in recent years to take on a leading role in international ICT standardization. However, many Chinese organizations experience, similar to other latecomers to standardization, limited success when contributing to standardization processes, a phenomenon also referred to as the standardization gap. The literature on standardization to date has paid little attention to how Chinese latecomers enter and influence international standardization processes that have traditionally been shaped by organizations from industrialized countries. We therefore analyze the country-of-origin effect as well as factors such as experience and collaboration for successful contributions of Chinese organizations to standards. Using data from the Third Generation Partnership Project (3GPP) and binary logistic regression analysis, we are able to show that, in our sample, contributions from Chinese latecomers are significantly less likely to be accepted than those from more established actors from industrialized economies. Moreover, our findings indicate that experience is closely associated with success in international ICT standardization, but not moderated by national origin. Therefore, Chinese latecomers might not be able to catch up if they move at the same pace as established competitors. They need to find a way to leapfrog extensive development steps, narrow the standardization capability gap, and thus strengthen their participation and influence. One way to do so might be through strategic collaboration, as our results suggest that Chinese organizations benefit more from collaborating with organizations from more established regions than vice versa, on which we call for further research to establish the causal mechanisms. 相似文献

The use of external knowledge for innovation (i.e., inbound or outside-in open innovation) has received substantial attention in the innovation literature. However, the “human side” of open innovation is still poorly understood. We consider the role of employee characteristics with respect to predicting firm-level openness. Drawing on the human capital, learning and creativity literatures, we theorize that knowledge diversity of the firm’s employees is positively associated with employees’ ability to identify and absorb external knowledge, which aggregates to increased firm-level openness—that is, firms’ use of external knowledge in their pursuit of innovation. Based on a combination of three data sources, namely, two survey data sources and register data, we find support for our hypothesis that employees’ educational diversity is positively associated with firm-level openness. However, we find no direct association between employees’ work history diversity and firm-level openness but rather—as also hypothesized—a conditional relationship based on educational background, which implies that diverse work history only has a positive impact at higher levels of educational diversity. To reduce endogeneity concerns, we undertake a series of robustness checks. 相似文献

The frequent occurrence of sandstorms in north China in recent years had an immediatebearing upon the ecological degeneration of grasslands in Inner Mongolia. The long-time preda-tory exploitation of the primordial ecosystems leads to the degradation of the sandy grasslands.In this aspect, human infringement is the predominant reason while natural retrogression issecondary. In the taming of the sandstorm scourge, therefore, the key lies in casting off the live-stock-grazing pressure on the de… 相似文献
