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

Hiring employees with advanced education, training, and experience has been a prevalent human resource practice in dynamic science-based industries, and a growing body of literature has demonstrated the importance of scientists in such fields. Little research has attempted to distinguish the functional from the symbolic roles of scientists, however. We develop an integrative theoretical framework to separate the productive and legitimating effects of scientists on strategic alliance formation of firms. Results from a longitudinal analysis of more than 300 U.S. biotechnology firms between 1988 and 1999 suggest a positive relationship between ratio of scientists and R&D alliance partners as well as a positive relationship with finance alliance partners. Scientists influence partner attraction more strongly for firms that are less-well-connected, and they become less prominent in fostering finance ties as the industry practice of partnership becomes more institutionalized. We conclude that scientists serve more than just a research function in knowledge-intensive industries. Implications for building interorganizational networks and managing human resources in such industries are discussed.  相似文献

Up until the 1950s, the history of mathematics was an integral part of the history of science. To George Sarton and his contemporaries, mathematics was the rational skeleton that organized science and held it together, and its history was a fundamental component of the broader history of science. But when historians began focusing on the cultural roots of science rather than its rational structure, the study of mathematics was marginalized and ultimately excluded from the history of science. The alienation between the two fields is detrimental to both, and in recent years there has been a sustained effort to reestablish meaningful communication between the two. This time, however, mathematics is seen not as the static skeleton of science but, instead, as a dynamic and historically evolving field in its own right-just like science itself. The new approach allows for a culturally sensitive study of mathematics, as well as a new and fruitful relationship between the history of science and the history of mathematics. The essays in this Focus section offer a sampling of the new approaches, opening the way to a rapprochement between fields that have gone their separate ways but should by rights be closely interconnected.  相似文献

In the era of the Internet of Things (IoT), emerging artificial intelligence (AI) technologies provide various artificial autonomy features that allow intelligent personal assistants (IPAs) to assist users in managing the dynamically expanding applications, devices, and services in their daily lives. However, limited academic research has been done to validate empirically artificial autonomy and its downstream consequences on human behavior. This study investigates the role of artificial autonomy by dividing it into three types of autonomy in terms of task primitives, namely, sensing, thought, and action autonomy. Drawing on mind perception theory, the authors hypothesize that the two fundamental dimensions of humanlike perceptions—competence and warmth—of non-human entities could explain the mechanism between artificial autonomy and IPA usage. Our results reveal that the comparative effects of competence and warmth perception exist when artificial autonomy contributes to users' continuance usage intention. Theoretically, this study increases our understanding of AI-enabled artificial autonomy in information systems research. These findings also provide insightful suggestions for practitioners regarding AI artifacts design.  相似文献

We study how trademarks affect reuse of creative works in the comics industry. As a creative industry, the comics industry systematically relies on copyrights. But trademark protection can also be exploited to generate income from the reuse of comic characters or to strategically exclude others from reuse. Our unique data set combines US trademark records of comic characters with information on reuse in print media and franchise products from 1990 to 2017. We find that, on average, additional trademark protection is associated with a reduction in reuse in printed comic books of about 19%. We highlight three mechanisms: first, the negative relationship between trademarking and reuse has been especially pronounced since the early 2000s, when the arrival of digital technologies lowered the costs of entry, promotion, and distribution. Second, our results are driven by less reuse by third parties, not trademark holders. Third, reuse is higher when trademark owners license comic characters to third parties. The negative association between trademarking and reuse carries over to franchise products, but it is weaker and tied to the era of digitization, with a 2% decline in reuse in franchise movies and 9% lower reuse in video games.  相似文献

We examine patent licensing business models of non-practicing entities that generate revenue by selling, licensing, or litigating patents. They may also pursue R&D activities, invent new technologies, or provide services to inventors or product companies. We describe their business models and patent market behavior and then compare their litigation strategies against product companies using a matched sample of highly comparable patents. The main differences among patent licensing firms stem from their technological capabilities, patent portfolio sizes, and external relationships. We find that licensing firms with technological capabilities often pursue litigation until decision and engage in forum shopping. In contrast, litigation incidence, parties involved, and outcomes are primarily determined by patent characteristics, not entity types. Licensing business models drive the acquisition of certain types of patents that influence the outcomes of the patent system. We argue that patent policy should strengthen mechanisms to discover invention quality rather than focus on the amount of litigation or types of entities.  相似文献

This paper intends to introduce briefly the thematic progression patterns in Systemic- Functional Grammar, then analyze its application in "The Great Learning" which is one of the classics of the Confucius and his disciples. The analysis of the thematic progression patterns of "The Great Learning" is meaningful for both understanding and appreciating "The Great Learning".  相似文献

B2B livestreaming has become increasingly popular, but few studies have investigated the role of streamers in these B2B livestreaming events. In contrast to the existing studies that explored the appearance and professionalism of streamers and focused on the B2C livestreaming commerce, this study analyzes how streamers’ linguistic characteristics relate to the livestreaming sales performance in online B2B marketplaces by conducting a streamer-level analysis. By combining deep learning and econometric analysis on a livestreaming dataset consisting of 915 livestreaming events across 14 industry categories from a B2B commerce platform, this study specifically examines the impact of three speech acts (i.e., assertive, expressive, and directive speech acts) on sales performance. We first extract three speech acts by combining Word2Vec and Bi-GRU network with Attention Mechanism (WBA), then use econometric models to examine the effect of the streamer's speech acts on sales performance, and finally explore the moderating roles of product-level factors (i.e., product novelty and product category). The results show that the assertive and directive acts have a positive effect on sales performance, but the expressive acts have a negative effect on the sales performance. In addition, this study also provides strong evidence that the effects of these speech acts on sales performance are highly dependent on the novelty of the live product. This moderating effect is particularly significant for sensory products.  相似文献

In this paper, we analyze the extent to which University-Level Support Mechanisms (ULSMs) and Local-Context Support Mechanisms (LCSMs) complement or substitute for each other in fostering the creation of academic spin-offs. Using a sample of 404 companies spun off from the 64 Italian Science, Technology, Engineering, and Mathematics universities (STEM universities) over the 2000–2007 period, we show that the ULSMs’ marginal effect on universities’ spin-off productivity may be positive or negative depending on the contribution offered by different LCSMs. Specifically, in any given region, ULSMs complement the legislative support offered to high-tech entrepreneurship whereas they have a substitution effect with regard to the amount of regional social capital, regional financial development, the presence of a regional business incubator, regional public R&D expenses as well as the level of innovative performance in the region. Results support the idea that regional settings’ idiosyncrasies should be considered for universities to develop effective spin-off support policies. This paper contributes to the debate on the evaluation of economic policies supporting entrepreneurship.  相似文献

Dr Peter Wilmshurst is a consultant cardiologist. He is a leader in his field, and also a whistleblower, drawing attention to that which he believes to be wrong. He was presented with the HealthWatch Award 2003. Peter Wilmshurst has clashed with universities, editors, the medical establishment, and – perhaps inevitably – with the pharmaceutical industry. It is this last encounter that has taken him to court and that has made explicit and very public the relevance of the UK's libel laws to scientific research.  相似文献

Existing scholarship on the debates over expertise in mid-nineteenth-century Britain has demonstrated the importance of popular writings on the sciences to definitions of scientific authority. Yet while men of science might position themselves in opposition to the stereotype of the merely popular writer, the self-identity of the popular writer remained ambiguous. This essay examines the careers of William Charles Linnaeus Martin (1798-1864) and Thomas Milner (1808-ca. 1883) and places them in the context of others who made their living by writing works on the sciences for the general reader. Martin wrote on zoology and Milner moved between astronomy, geology, and geography. The essay unravels the close but ambivalent relationship between the professions of authorship and of science and highlights writing as another aspect of scientific practice. Both writers were moderately financially successful, but Martin's sense of failure and Milner's satisfaction reflect their contrasting images of their professional identity.  相似文献
