对英国现代主义时期颇有争议的作家D.H.劳伦斯的综述,国内主要对其全部作品作了20年的评述。到目前为止国内外尚未见到对其“最好”、“最严肃”、“内容丰富”的长篇小说《虹》的研究综述,鉴于此,论文从历史的纬度对劳伦斯《虹》的50年(1955—2009)研究进行回顾与综述。 相似文献

This article proposes a theoretical framework of transcultural risk communication to examine how global connectivities influence communication about H1N1 flu. A case study was conducted to investigate risk management policies at global, regional, and translocal levels to cope with health threats posed by the emerging H1N1 flu epidemic. We explored how risk management approaches by Chinese Internet users facilitated the employment of a unique risk measure of exit and entry screening for returnees to China. 相似文献

R.H.托尼是英国工党史上一位颇为重要的人物,他对20世纪的英国工党政治产生了巨大影响:一方面,通过起草《人人接受中等教育》、《工党与国家》和《为了社会主义与和平》等重要政策,托尼对20世纪英国工党的发展作出了巨大贡献;另一方面,无论是对工党左派还是右派,无论是对老工党还是新工党,托尼的思想都具有持久的影响力,成为其政策制定的重要理论依据之一。 相似文献

Management literature has identified high-skilled human capital as a crucial dimension of innovation processes at the firm level. In this study, we introduce an alternative view of human capital based on the tasks that firms’ workers perform. We propose a measure of cognitive analytical and interpersonal tasks: the degree of abstractism. We argue that the level of abstractism of a firm has an effect on a firm's propensity to innovate and on its product innovation performance. We hypothesize that while the degree of abstractism has a linear positive relationship with the propensity to innovate, the relationship between abstractism and product innovation performance follows an inverted u-shaped relationship. We find partial support to our hypotheses using data from more than six thousand Portuguese firms. We discuss how these results change our understanding of the relationship between human capital and innovation at the firm level. 相似文献

A vast literature on technology transitions within industries suggests that early phases of new technologies are marked by periods of intense experimentation, but we know little about the conditions under which these periods emerge. We apply inductive, grounded theory-building techniques to examine what prompts firms to experiment across one emerging technology platform—plug-in electric vehicles (PEVs)—in China. Triangulating annual vehicle make and model sales data from 2003 to 2016 (plus monthly data from 2010 to 2016); 112 English and Mandarin archival documents from industry, academic, and news outlets; and 51 semi-structured interviews with industry, government, and academic stakeholders, we develop four in-depth case studies. We find that in contrast to the innovation trajectories of multinational and Chinese arms of joint venture (JV) firms, independent domestic Chinese firms (those with no history of international JV partnerships) are undertaking significant experimentation across multiple levels—infrastructure, core system, subsystem, and component—of the emerging PEV technology platform. We propose the concept of “institutional complementarities” to describe how interactions among institutions—here the national JV regulation and local market support and subsidies—may have turned regional markets into protected laboratories, extending the incubation periods for independent domestic firm experimentation. While this diverse experimentation may be an important antecedent of technology transition, consolidation induced by national policy standardization or competitive pressure may be required for PEV innovations to scale beyond their early, protected regional markets. 相似文献

We investigate in the context of crowdsourcing how seekers can increase open innovation performance, measured as received solver attention, by making two strategic decisions: selecting innovation tasks that are well suited for crowdsourcing and choosing between the potentials of status signalling through identity disclosure versus enjoying the benefits of anonymity. Drawing on uncertainty reduction theory, we suggest that a well-articulated problem statement reduces uncertainties of potential solvers and increases their willingness to participate. We argue that the ability of seekers to draft high-quality problem statements depends on the distance between the problem domain and their current knowledge stock. An analysis of 637 crowdsourcing projects finds that problem-seeker knowledge distance and received solver attention are curvilinear related such that moderate levels of knowledge distance maximize solver participation. However, high-status seekers who engage in identity-based status signalling are able to benefit from crowdsourcing across all levels of problem-seeker knowledge distance. 相似文献

This study investigates the effect of project-level collaboration breadth (i.e., the number of collaboration partner types) and collaboration depth (i.e., the intensity of the interactions with these partners) on the incremental and radical innovation performance of innovation projects. The econometric analyses, based on a Community Innovation Study sample of 218 innovation projects conducted in German manufacturing companies, reveal inverted U-shaped relationships between collaboration breadth and radical innovation performance and between collaboration depth and incremental innovation performance. These curvilinear effects speak to the high sensitivity of innovation projects to the extent of collaborative activity, which implies that practitioners should exert caution in managing collaborative innovation projects. This study contributes to the understanding of project-level open innovation and to the overall understanding of the performance effects of innovation collaboration, which, following recent assertions in the literature, could be flawed by analyses conducted at the organizational level. 相似文献

This article draws attention to literary works which have been influenced by microscopy, or in which microscopy has played a significant role. The work of writers including Jonathan Swift, Voltaire, George Eliot, H. G. Wells and D. H. Lawrence is discussed. In many cases these authors had direct experience of operating microscopes and viewing the wonders of the microscopic world. However, with the increasing separation of the two cultures, recent examples of microscopy in literature are rare. 相似文献
