William Bateson was one of the pivotal figures in the early history of genetics, having championed the promise of Mendelism to unravel the secrets of heredity. Many refer to the "school" of genetics he directed at Cambridge between 1900 and 1910, but few note that Bateson's group consisted primarily of women. Bateson turned to botanists, zoologists, and physiologists associated with Newnham College, Cambridge, for critical assistance in advancing his research program at a time when Mendelism was not yet recognized as a legitimate field of study. Cambridge women carried out a series of breeding experiments in a number of plant and animal species between 1902 and 1910, the results of which provided crucial evidence that both supported and extended Mendel's laws of heredity. This essay shows how the situation of women in science in the early twentieth century was a factor--along with scientific, institutional, social, and political developments--in establishing the new discipline of genetics.  相似文献

In 1920, the German botanist Hans Winkler coined the concept of the ‘genome’. This paper explores the history of a concept that has developed in parallel with advances in biology and supports novel and powerful heuristic biological research in the 21st century. From a structural interpretation (the genome as the haploid number of chromosomes), it has changed to keep pace with technological progress and new interpretations of the material of heredity. In the first place, the ‘genome’ was extended to include all the material in the nucleus, then the sum of all genes, and (with the discovery of the structure of DNA) the sum of the nucleotide base sequences. In the early 21st century, it has become a much more complex and central concept that has spawned the growing field of studies referred to as the ‘omics’.  相似文献

During the French Revolution, there appeared a striking and far-ranging medical literature on heredity, reproduction and biological 'perfectibility'. In some ways anticipating ideas associated with modern eugenics, these writings emerged from radical revolutionary projects for 'physical and moral regeneration' and incarnated deep-seated desires to transform French society and make a 'new man' in mind and body. But by breaking down boundaries between public and private life, doctors did more than just try to regulate intimate sexual behaviour. Instead, they proffered a more intimate vision of civic volunteerism, in which sexual hygiene and domestic practices allowed their patients to imagine new forms of society and gave them ways to attain these socio-political dreams. Moreover, they were responding to powerful new worries about heredity and sought to counsel their patients in the ways of family panning. By the end of revolutionary period, then, medical and lay thinkers had transformed the marriage bed and household into a specially controlled environment - a kind of affective laboratory - in which conscientious parents could make healthy children and raise them in the context of specific political and social values.  相似文献

企业社会责任是企业实现可持续发展的重要实践方式,如何驱动企业可持续性的社会责任行为成为研究的重要议题。社会信任作为宏观经济运行与微观企业市场活动的“润滑剂”,对企业的市场行为与社会行为产生不可忽视的作用。传统的研究主要研究外部正式制度对企业社会责任的影响,忽视了社会信任作为一种非正式制度在驱动企业社会责任实践中产生的重要作用。本文基于2009-2017年中国A股上市公司为研究样本,实证考察了社会信任对企业社会责任的影响效应,并检验了外部正式制度与企业内部高管激励制度在社会信任(非正式制度)与企业社会责任的调节效应;进一步验证了基于工具竞争逻辑主导下的企业社会责任在社会信任与企业创新之间的中介作用,验证企业社会责任的工具价值效应。研究结果表明:(1)社会信任对企业社会责任产生显著的正向影响,异质性分析结果表明在产权、披露环境以及行业追随等方面存在异质性;(2)外部正式制度(市场化环境)在社会信任与企业社会责任之间产生正向调节作用,呈现出正式制度与非正式制度对企业社会责任的协同倍增效应;(3)企业内高管股权激励制度在社会信任与企业社会责任之间产生负向调节作用,呈现出企业内激励制度与企业外非正式制度对企业社会责任的替代效应;(4)企业社会责任在社会信任与企业创新之间产生部分中介作用,即Porter和Kramer(2006)提出的企业社会责任的战略竞争工具效应得到实证结果的支持。本研究在理论层面上基于“内外结合”的视角丰富了企业社会责任驱动因素的研究,拓展了社会信任作用与企业社会行为的影响机制,在实践层面为政府以及企业重新审视社会信任的价值效应提供经验证据,也为企业履行社会责任发挥社会责任的竞争工具效应提供经验启示。  相似文献

Over one billion people are currently using social media such as social websites (Facebook Newsroom, 2015); consequently, numerous academic scholars have developed interest in studying the use of social media and social networks. However, few studies have focused on examining the core factors of social networks. In this study, we collected studies on social-network-related topics that were published between January 1996 and December 2014, assembling a total of 2565 articles and 81,316 citations. Co-citation analysis and cluster analysis were applied to verify seven main factors regarding social networks: (a) the measure of complex social networks; (b) community structure; (c) strong and weak ties; (d) the evolution of social networks; (e) network structure and relationship; (f) value concept and measurement strategies; and (g) social capital. Finally, the results of this study were further discussed to elucidate the core topics relevant to social networks.  相似文献

Interactivity has been identified as a core concept of new media, yet despite nearly three decades of study and analysis, we scarcely know what interactivity is, let alone what it does, and have scant insight into the conditions in which interactive processes are likely to be consequential for members of a social system. This article attempts to address this deficiency by critiquing three self-defeating tendencies and an erroneous assumption of interactivity research, then proposes four basic propositions around which systematic knowledge regarding interactivity in society may be built. In the spirit of bridging mass and interpersonal processes, a model of interactivity is proposed to initiate discussion about the concept as a cross-level and multivalent phenomenon—one with both positive and negative consequences—and to spur more socially relevant research. For interactivity to succeed as a concept, it must have some meaningful social and psychological relevance beyond its technical status as a property of media systems or message exchanges.  相似文献

Participation in and adding content to social tagging tools is important for these tools to achieve their purpose of classifying and organizing information. Users of social tagging tools are driven to participate and add tags by extrinsic and intrinsic motivation. Extrinsic motivation is dominating research as a main predictor of why users use information systems. Social tagging tools, as a subset of social media tools, are distinguished by their unique social aspect that makes intrinsic motivation a potential driver for users to add tags to content. Intrinsic motivation, when applied to social tagging tools, could entail many shades that represent different users’ motives for using such tools. In this paper, we add a rich concept of intrinsic motivation to include hedonism as a main predictor of users’ behavior on social tagging tools. We empirically validate a previously proposed theoretical model of three dimensional concepts of hedonism with three components describing individuals’ hedonic state when interacting with social tagging tools: explorability, curiosity, and enjoyment. After a robust and thorough data analysis using structured equation modeling, the results confirm our theoretical model and suggest using a richer concept of enjoyment to reflect a hedonic dimension when investigating intrinsic motivation with interactive social media tools. Our validated model could be the spark of new factors that have the potential to influence user acceptance of information systems in general and in social media tools. This research contributes to the development of attitude-behavior theories that could explain users’ acceptance of dynamic web  相似文献

Companies are increasingly relying on social media brand communities to interact with consumers and achieve business values. Thus, it is essential to understand how companies can extract value from consumers in social media brand communities. We develop a model clarifying the dual concept of consumer value and illustrating how consumer-perceived value can be transformed into consumer-generated value from a trust transfer perspective. Specifically, we identify three types of consumer-perceived value: utilitarian, hedonic, and social. We capture consumer-generated value in terms of purchase intention and social media word of mouth. Using a two-wave survey, our results strongly support the research model. Specifically, the three types of consumer-perceived values positively affect consumer trust in social media brand communities, which in turn leads to trust in brand and in social media and, thereafter, consumers’ subsequent social media word of mouth and purchase intentions. Our study makes several contributions to the strategic information systems literature concerning leveraging social media brand communities into business strategies. Theoretically, our study expands the understanding of the dual concept of consumer value in social media brand communities through the trust transfer theory. Practically, our study delivers insights for companies into how social media brand communities can be used as a strategic tool for achieving business values.  相似文献
