A Fusion Approach to XML Structured Document Retrieval     

Ray?R.?LarsonEmail author 《Information Retrieval》2005,8(4):601-629

In this paper we evaluate the application of data fusion or meta-search methods, combining different algorithms and XML elements, to content-oriented retrieval of XML structured data. The primary approach is the combination of a probabilistic methods using Logistic regression and the Okapi BM-25 algorithm for estimation of document relevance or XML element relevance, in conjunction with Boolean approaches for some query elements. In the evaluation we use the INEX XML test collection to examine the relative performance of individual algorithms and elements and compare these to the performance of the data fusion approaches.  相似文献

The Multiple In-group Identity Framework     

《Sport Management Review》2016,19(2):85-96

The effects of team identification on sport consumer behaviour are well established. Recent research, however, has moved beyond this perspective to examine how groups within and beyond the team identity influence consumption. Assimilating previous research findings, we advance a Multiple In-group Identity Framework (MIIF), which consists of three levels: (1) superordinate (e.g., team identity), (2) subgroup (e.g., specific stadium area), and (3) relational group (e.g., friends or family). In the MIIF, we conceptualise the complex array of groups to which a consumer may belong within a superordinate identity. Each level includes groups with varying degrees of inclusiveness, homogeneity, and interpersonal attachment to other consumers between members. Individuals seek out sub and relational group membership because solely identifying at the superordinate level may not provide optimal distinctiveness or sufficient interpersonal attachment to other consumers. This provides self-concept benefits that nourish and operate in complement with the superordinate identification. The extent that different in-group identities influence behaviour relates to their importance in a consumer's self-concept and relevance to context. We provide implications for theory and practice.  相似文献   

多学科交叉融合的新生工科专业建设     

林健 《高等工程教育研究》2018,(1):32-45

新生工科专业是指由不同工程学科的交叉复合,或由工程学科与其他学科的交叉融合而产生的新的工科专业,新生工科专业建设是新工科建设中一项十分复杂的核心工作,对新工科中其它类型的学科专业建设,以及高等教育其它学科专业领域的新专业建设具有重要的参考和示范作用。新生工科专业建设内容主要包括专业设置、专业培养方案制定、课程体系建设、教学内容形成、实践教育教学体系构建、创新创业教育体系构建等方面。与此同时,在新生工科专业建设时还需要重视科学研究对新生工科专业建设和人才培养的支撑作用。本文以新生工科专业建设为主题,依次对上述六方面内容进行讨论和分析,以期为相关院校开展新工科建设提供参考和借鉴。  相似文献

“Friend” or Foe? Why People Friend Disliked Others on Facebook     

Megan A. Vendemia  Andrew C. High  David C. DeAndrea 《Communication Research Reports》2017,34(1):29-36

This study explores the disconnection that exists between the number of friends and relationships people maintain in their face-to-face interactions and the number of connections people establish on social networking sites. Specifically, we examined the extent to which Facebook users “friend” people they dislike and find annoying on Facebook and the reasons people offer for engaging in these seemingly nonintuitive behaviors. The results indicate that, in a sample of college students (N = 305), the majority of Facebook users are friends with people they dislike on Facebook (61%) and actively read the postings of individuals even though they find their postings annoying (85%). Participants’ sex, intensity of Facebook use, and general relational anxiety all independently predicted the occurrence of friending disliked others and actively reading annoying postings. A uses and gratifications framework was adopted to develop a typology of reasons why people engage in these behaviors. Monitoring, surveillance, downward social comparison, and other explanations were provided by participants to account for their behavior on Facebook. How engaging in these online behaviors might affect the psychological well-being of individuals and quality of interpersonal relationships is discussed, and future directions for research are offered.  相似文献

The Expression of Dominance and Perceptions of Supervisor Credibility in Supervisor/Employee Relationships     

Alan C. Mikkelson  David Sloan  Colin Hesse 《Communication Research Reports》2017,34(4):287-296

In the workplace, a supervisor’s communication of dominance can be used to help accomplish tasks and complete work. Further, perceptions of credibility can be integral in influencing employees and creating an open work climate. The goal of this investigation was to understand how supervisors’ messages of dominance were related to perceptions of supervisor credibility. In this study, 303 participants working in various industries completed measures of interpersonal dominance and credibility about their direct supervisor. As hypothesized, influence and focus/poise were positively related to competence, goodwill, and trustworthiness, whereas conversational control was negatively related to goodwill and trustworthiness. Further, self-assurance was negatively related to goodwill. Regression analyses determined that influence and focus/poise had the strongest relationship to all three dimensions of credibility.  相似文献
