杨梦晴  朱庆华 《图书情报工作》2020,64(1):105-112

[目的/意义] 旨在对在线健康社区用户的个人健康信息管理行为特征进行分析，并在此基础上，对"平台-PHIM-健康目标"这一模式中的元素之间的关系进行探讨。[方法/过程] 选择患有红斑狼疮的在线健康社区用户作为调查对象。采用聚类方法对个人健康信息管理行为的总体测度水平不同的群体进行识别；利用单因素方差分析（One-way ANOVA）对不同群组进行比较研究。[结果/结论] 将依托在线健康社区进行的个人健康信息管理行为界定为健康信息发现、健康信息互动和健康信息分享。从数据分析结果来看，首先，在线健康社区的红斑狼疮患者在个人健康信息管理行为水平上存在显著的高低差异。第二，用户所感知到的社会支持与其个人健康信息管理水平存在正相关关系。第三，个人健康信息管理与用户健康目标之间存在正相关关系。本研究为在线健康社区完善其服务方式，促进慢性病人个人健康信息管理水平提高提供合理建议。  相似文献   

国际乒联频繁修改规则的批判性反思     

王翾  梁勤超  李林 《武汉体育学院学报》2020,54(10):88-94

采用文献资料等方法，梳理国际乒联21世纪以来的规则改革，反思其存在的问题。21世纪以来，国际乒联在器材、技术和赛制等方面进行了一系列的改革。一系列规则改革在技术上使得运动员技术选择和使用随意性增大，比赛胜负的偶然性增大；在国际乒坛秩序上产生了正、反两方面影响，一方面改变了中国队"一家独大"的局面，国际大赛的奖牌分布趋于多元化，另一方面，使得运动员打法逐渐呈现单一化趋势。同时国际乒联频繁修改规则还存在规则修改程序正义性、规则相对稳定性，以及权力行使过于随意等问题。要维系国际乒坛秩序的良性发展，国际乒联还需出台具体的规则改革制度，保证竞赛规则的相对稳定性，并合理行使规则修改的权力。  相似文献   

Mela: festival scenes in South Asian cinema     

John Hutnyk 《Inter-Asia Cultural Studies》2018,19(1):129-147

This article examines a recurrent film motif across a number of South Asian films, mostly called Mela. It also offers some observations on melas, actual and allegorical, as represented in films but often seeming to exceed their containment in context so as to say more about the conviviality of life, where this is at issue, where life is at a juncture in need of resolution within the cycle of becoming. The issues of violence, loss, national identity, politics of interpretation and repetition in ideology are canvassed. While the essay is focused upon Mela films themselves, and South Asian film more broadly, it has of course been important to note work by scholars such as M. Madhava Prasad, Ashish Rajadhyaksha, Anjali Gera Roy, Tejaswini Niranjana, Gayatri Chakravorty Spivak and the help of my students, some of whom are named below.  相似文献   

‘Who is zooming who’? A study of young PE-students in their figurations     

Stine Frydendal Nielsen  Lone Friis Thing 《Sport, Education and Society》2019,24(5):480-490

The article presents an analysis of 93 essays written in an upper secondary school context. The essays were collected in relation to a larger research project, which went on for 5 years in a Danish upper secondary school (2010–2015). The material represents both genders and the students are 15–17 years old. We deploy a theoretical framework taken from Norbert Elias’ notion on established-outsider relations [Elias, N., &; Scotson, J. L. (1994 [1965]). The established and the outsiders. London: SAGE] as well as his use of personal pronouns [Elias, N. (1978). What is sociology? London: Hutchinson, Elias, N. (2001). The society of individuals. New York: The Continuum International Publishing Group] in illustrating how people negotiate, position and navigate within figurational contexts [Elias, N. (1994 [1939]). The civilizing proces. Oxford: Blackwell.]. We do this in an effort to interpret how young people negotiate ‘we-I-relations’ when it comes to their sporting identity. Elias’ processual framework provides a tool for a much needed analysis of how young people continually orientate and develop their sense of selves. The web of human interdependencies and processes of change are key words when it comes to understanding the social practices and doings of the students’ constructions of self-steering. What social scientists may see as laziness and drop-outs of sports [Seippel, Ø. (2016). Prek, vekker og kjedelig? Trening og mening blant ungdom: 1985–2013. In Ø. Seippel, M. K. Sisjord, &; Å Strandbu (Eds.), Ungdom og Idrett. Oslo: Cappelen Damm Akademisk] can in the essays of students be analysed as a struggle for group connectedness and social inclusion in the classroom. The results of our research show that identity is a multiple concept and an ongoing process of emotional work [Elias, N. (1987). On human beings and their emotions: A process-sociological essay. Theory Culture Society, 4, 339–361], but also a power balance of playing and presenting what is imagined as the right performance as not being shamed as outcasts.  相似文献   

Data Visualization as Participatory Research: A Model for Digital Collections to Inspire User-Driven Research     

A. Miller 《Journal of Web Librarianship》2019,13(2):127-155

The emerging creative practices of digital collections are increasing in prominence thanks to the access to, and appeal of, data visualizations. Interactive data visualizations, such as a map, timeline, chart, graph, or artist’s rendering of data, enable users to pursue their own research interests within a collection and participate in new areas of research. Use of these data visualizations enhances the scope of the collection and enables a modern and diverse thematic collection to emerge. This article considers the question: Does the addition of data visualizations affect how users participate with a research collection? Impacts on collection development, application of user-centered design, and analysis of users’ exploratory strategies are discussed. Examples of data visualizations used in digital humanities projects and digital collections are presented as case studies.  相似文献   

人力资本和社会资本对中国退役运动员收入影响比较     

张晓丽  阎晋虎 《上海体育学院学报》2020,(4):31-40

从人力资本和社会资本的视角出发,以316名中国退役运动员为研究对象,探讨这2种资本对退役运动员收入的影响,结果显示:①中国退役运动员的收入差异较大,平均收入状况不容乐观;②在人力资本的各观测变量中,运动等级、受教育程度、身体健康状况和职业技能培训依次对退役运动员收入产生影响;③在社会资本各观测变量中,弱关系和网络异质性对退役运动员收入影响显著;④人力资本有助于退役运动员进入中等收入群体,社会资本有助于其进入高收入群体;⑤人力资本和社会资本对退役运动员的收入提升作用显著,且人力资本作用高于社会资本。基于此,从政府和个体层面提出提升退役运动员人力资本和社会资本的建议。  相似文献   

离岸集装箱码头新装卸工艺模式下陆域集疏运堆场堆存空间分配     

杨晓斌  余思勤  沈一帆 《上海海事大学学报》2020,41(4):8-14

离岸集装箱码头因其岛屿面积限制，难以通过扩建码头内部堆场增加吞吐能力。为解决这个问题，提出一种离岸集装箱码头新装卸工艺模式。新装卸工艺模式是通过在离岸集装箱码头附近的陆域地带建设陆域集疏运堆场,与离岸集装箱码头进行协同装卸作业的模式。陆域集疏运堆场堆存空间分配的目标是满足离岸集装箱码头装卸作业预翻倒要求;单批次输送集装箱的量受到陆岛运输最大通行能力限制。根据上述目标与特点，构建新装卸工艺模式下陆域集疏运堆场堆存空间分配模型，并设计蒙特卡洛树搜索算法进行求解。通过算例分析验证模型的有效性。结果表明该方法能够满足陆域集疏运堆场堆存空间分配需求并提高离岸集装箱码头的吞吐能力。  相似文献

协同搜索过程中用户交流内容与模式研究     

张璐  张鹏翼  刘畅 《图书情报知识》2020,(3):51-62

[目的/意义]旨在分析协同搜索用户在信息搜索任务过程中的交流内容与模式,从而理解协同搜索用户的关注重点与搜索过程。[研究设计/方法]基于书籍交互检索平台(CLEF-Social Book Search)设计实验,共招募18名被试完成两种搜索任务,通过录音记录对话并对其进行编码和分析,总结交流内容特征和模式。结合任务类型、认知类型组合、服务器记录的搜索交互行为日志以及问卷收集的搜索体验进行了探索分析。[结论/发现]从交流内容上看,协同搜索用户主要理解与评判书目信息、商讨搜索任务计划;比起认知类型不同的用户,相同认知类型的用户在操作交互方面交流更多,在评判决策方面交流较少。交流模式依据讨论内容比重可分为理解评判型、评判主导型、均衡交流型三种,评判主导型用户的任务完成满意度最高。[创新/价值]协同搜索用户的交流反映出搜索过程中需要与同伴商讨协同的焦点,也是需要系统提供协助的重点,给协同搜索系统设计提供一定参考。本研究针对协同搜索的交流内容设计的编码系统对相关的协同交流研究也有借鉴意义。  相似文献   

Beyond traditional collaborative search: Understanding the effect of awareness on multi-level collaborative information retrieval     

Nyi Nyi Htun  Martin Halvey  Lynne Baillie 《Information processing & management》2018,54(1):60-87

Although there has been a great deal of research into Collaborative Information Retrieval (CIR) and Collaborative Information Seeking (CIS), the majority has assumed that team members have the same level of unrestricted access to underlying information. However, observations from different domains (e.g. healthcare, business, etc.) have suggested that collaboration sometimes involves people with differing levels of access to underlying information. This type of scenario has been referred to as Multi-Level Collaborative Information Retrieval (MLCIR). To the best of our knowledge, no studies have been conducted to investigate the effect of awareness, an existing CIR/CIS concept, on MLCIR. To address this gap in current knowledge, we conducted two separate user studies using a total of 5 different collaborative search interfaces and 3 information access scenarios. A number of Information Retrieval (IR), CIS and CIR evaluation metrics, as well as questionnaires were used to compare the interfaces. Design interviews were also conducted after evaluations to obtain qualitative feedback from participants. Results suggested that query properties such as time spent on query, query popularity and query effectiveness could allow users to obtain information about team's search performance and implicitly suggest better queries without disclosing sensitive data. Besides, having access to a history of intersecting viewed, relevant and bookmarked documents could provide similar positive effect as query properties. Also, it was found that being able to easily identify different team members and their actions is important for users in MLCIR. Based on our findings, we provide important design recommendations to help develop new CIR and MLCIR interfaces.  相似文献
