“It’s who you know, not what you know,” is a familiar phrase—often repeated by professionals in Hollywood. The present study focuses on “who knows who” among Hollywood television writers. Using network analysis, this exploratory study identifies the degree of centralization and types of connections found in this elite writers’ network. Results show a great deal of collaboration in the network, and while male writers are more connected overall in Hollywood, women are more likely to be brokers—a structurally advantageous position. The authors provide explanations for collaboration patterns, especially with regard to gender differences in network roles, and propose avenues for further research. 相似文献

Collaboration usually has a positive effect on researchers’ productivity: researchers have become increasingly collaborative, according to recent studies. Numerous studies have focused on enhancing research collaboration by recommendation technology and measuring the influence of researchers. However, few studies have investigated the effect of collaboration on the position of a researcher in the research social network. In this paper, we explore the relationships between collaboration and influence by social analytical methods, which are pertinent to analyzing the network structure and individual traits. We evaluate three aspects of the researchers’ influence: friendship paradox validation, social circle, and structure of a researcher's ego network. Furthermore, the ”six degrees of Bacon number” theory, generalized friendship paradox, and triadic closure theory are introduced to support our analysis. Experimental results show that collaboration can help researchers increase their influence to some extent. 相似文献

The rapid growth of scientific collaboration and its significant role in promoting academic productivity has attracted increasing scientific community attention. The collaboration networks have become a powerful tool for studying scientific collaboration. Collaboration networks commonly used in research treat the collaborators as equal in status. However, the roles and contributions of different collaborators are not the same. Those differences are usually reflected through the signature order of academic achievements. This paper expands the construction of scientific collaboration networks with a directed collaboration network (DCN) to describe the different roles of collaborators and the connectivity and strength of collaborations. We analyzed the theoretical properties of the DCN and constructed evaluation indexes describing the diversity of collaboration order. Based on a case study of published papers in the business field, we discuss the value of the DCN in the characterization and evaluation of scientific collaboration and compare the DCN with two other collaboration networks. We found that the DCN provides a powerful new approach for investigating collaboration laws and patterns. 相似文献

中文医学学术期刊发表英文文章的实践与思考 总被引：1，自引：0，他引：1
中文医学学术期刊发表英文文章的现象较为普遍.通过对发表在<吉林大学学报(医学版)>上的112篇英文文章的发表时间、栏目、作者分布及被引用情况和其他3种较权威医学学术期刊发表的英文文章的数量及被引用情况进行分析,发现中文期刊发表的英文文章虽然具有较高的学术价值,但被国内期刊引用率明显低于同期发表的中文文章,SCI-E检索显示被引频次为0,认为中文医学学术期刊发表英文文章并没有起到扩大传播范围、促进期刊国际化的作用,而且浪费宝贵的信息资源.建议中文医学学术期刊不宜刊发英文文章,在国内应首选英文版期刊发表英文文章. 相似文献

This study introduces a hybrid approach (i.e., a social network analysis technique and triple helix indicators) to study certain aspects of the e-government (EG) domain that would otherwise remain hidden when using conventional analytic tools. Particularly, we provide network analysis of the EG research domain by focusing on the network collaboration between regions, nations and institutions. We collected and analyzed 1091 scholarly papers which were classified as being about “e-government” by the Web of Science database. The results indicate that hybrid method can be used to understand certain network-level structures and patterns in the EG domain which are beyond the scope of the predominantly-used systematic literature review (SLR) method. Particularly, the hybrid method is useful in understanding collaboration patterns between countries, institutions and regions in the EG domain, identifying key players by studying their network properties (i.e., degree centralities); and in understanding the pattern of relations among universities, industries, and government. The implications of these results in terms of research and practice, and study limitations are discussed. 相似文献

作者科研合作网络模型与实证研究 总被引：1，自引：1，他引：1
基于科研论丈作者合作方式，建立一个作者科研合作网络模型。通过理论分析和仿真验证，网络模型节点的度分布（作者合作人数）符合幂率分布，该网络是一种无尺度网络模型。为了说明作者合作网络模型的有效性，对2001年1月至2006年12月期间发表在“图书情报工作》期刊上的科研论文进行统计，建立作者合作网络。对作者合作网络进行数据分析，结果与网络模型结论一致，因此该模型可以很好地描述作者合作网络的演化过程。 相似文献

Many, if not most network analysis algorithms have been designed specifically for single-relational networks; that is, networks in which all edges are of the same type. For example, edges may either represent “friendship,” “kinship,” or “collaboration,” but not all of them together. In contrast, a multi-relational network is a network with a heterogeneous set of edge labels which can represent relationships of various types in a single data structure. While multi-relational networks are more expressive in terms of the variety of relationships they can capture, there is a need for a general framework for transferring the many single-relational network analysis algorithms to the multi-relational domain. It is not sufficient to execute a single-relational network analysis algorithm on a multi-relational network by simply ignoring edge labels. This article presents an algebra for mapping multi-relational networks to single-relational networks, thereby exposing them to single-relational network analysis algorithms. 相似文献

SUMMARY This article will discuss three years of collaboration between the Freshman Engineering Program and the Engineering Library of the University Library System at the University of Pittsburgh. This collaboration has resulted in a library research project that is integrated into the freshman curriculum. The project ultimately provides the students with a research structure for presentations in an annual mock professional conference. The mission of the Freshman Engineering Program's academic and advising components is to create a first-year experience that promotes the student's continued pursuit of an engineering degree through commitment to clearly understood and self-declared goals. The goal for the Engineering Library is to introduce library research as a necessary skill-set for successful engineers. The successful outcome of all of these goals requires the collaboration between “teaching” faculty and “library” faculty and results in better prepared, more focused students. Developing and integrating a library research project into the freshman engineering academic curriculum is a significant opportunity for library instruction, and the approach demonstrated here may be transferable to other disciplines. 相似文献

This essay is a gendered analysis of the U.S. Department of Health and Human Service’s Healthy People 2010 initiative (HP 2010). HP 2010 sets national health goals and priorities for public health agencies throughout the nation with a stated goal to “reduce health disparities” (p. 2), including disparities based on “gender, race, education or income, disability, geographic location, or sexual orientation” (p. 11). Given the focus on women’s medical research since the 1990s and the continued presence of gendered health disparities, it is important to investigate how public health policy defines, depicts, and prioritizes issues related to women’s health, particularly poor and minority women. A close reading of three sets of chapters related to physical disease, health care services, and sexual health issues from the perspective of women suggests that despite renewed promises, the “multi‐causal web” approach to public health does not promote conditions that would empower marginalized groups because it fails to address sex differences in health advice and prioritize economic and political changes necessary for marginalized groups. Underlying these issues is a lack of consideration for the role of socially constructed gender roles along with race and class in health status and inequities. 相似文献

The benefits of transdisciplinary collaboration for addressing complex health problems are widely accepted; however, acknowledging the bumps and twists along the road that are inherent in those collaborations is often considered taboo. Academic norms that prevent open discussion of these challenges can have counter-productive results. This essay describes the major education efforts, milestones, and footfalls in the development of an effective partnership between communication-trained researchers in a College of Journalism and Communications and medical researchers in a College of Medicine. We hope it can serve as “best practice” for understanding the value of team science and interdisciplinary research collaborations. 相似文献
