Referenced Publication Years Spectroscopy applied to iMetrics: Scientometrics,Journal of Informetrics,and a relevant subset of JASIST     

《Journal of Informetrics》2014,8(1):162-174

We have developed a (freeware) routine for “Referenced Publication Years Spectroscopy” (RPYS) and apply this method to the historiography of “iMetrics,” that is, the junction of the journals Scientometrics, Informetrics, and the relevant subset of JASIST (approx. 20%) that shapes the intellectual space for the development of information metrics (bibliometrics, scientometrics, informetrics, and webometrics). The application to information metrics (our own field of research) provides us with the opportunity to validate this methodology, and to add a reflection about using citations for the historical reconstruction. The results show that the field is rooted in individual contributions of the 1920s to 1950s (e.g., Alfred J. Lotka), and was then shaped intellectually in the early 1960s by a confluence of the history of science (Derek de Solla Price), documentation (e.g., Michael M. Kessler's “bibliographic coupling”), and “citation indexing” (Eugene Garfield). Institutional development at the interfaces between science studies and information science has been reinforced by the new journal Informetrics since 2007. In a concluding reflection, we return to the question of how the historiography of science using algorithmic means—in terms of citation practices—can be different from an intellectual history of the field based, for example, on reading source materials.  相似文献   

WHO西太平洋地区医学索引建设进展与问题     

王军辉  钱庆  方安  郑见立 《中华医学图书馆杂志》2014,(2):75-79

介绍了WPRIM （WHO西太平洋地区医学索引）的主要发展历程以及在期刊遴选、检索服务平台建设和数据采集等方面所取得的进展。用户日志分析表明,WPRIM已经初步具备了一定的国际影响力,但还不是一个相对成熟的区域性国际医学索引,并从宣传和推广、项目发展资金、期刊评审和数据采集方面提出了建议。  相似文献   

基于引文网络的医学各学科间知识流动的规律与启示     

李盈  许萍 《中华医学图书馆杂志》2014,(12):1-5

以CNKI引文数据库医药卫生专题下的数据为研究对象,利用社会网络分析方法,分析了我国医学领域内的知识交流特点。结果表明：临床医学的知识流入量和知识流出量都位居第一,是知识交流网络中的核心;基础医学是其他医学学科的理论基础,属于医学网络中的重要知识源;中医学与外科学及其他临床类学科的交流密切;在跨学科医学研究中肿瘤学表现得比较活跃;口腔医学和精神病学在知识交流网络中与其他学科的交流较少,是独立性较强的两个学科。利用这些特点开展学科信息推送服务,可提高信息服务的针对性,加速不同医学学科间的知识交流,推动医学领域内的跨学科合作研究。  相似文献

Social Media,Subjectivity, and Surveillance: Moving on From Occupy,the Rise of Live Streaming Video     

Elise Danielle Thorburn 《传播与批判/文化研究》2014,11(1):52-63

This article seeks to critically examine the practical application of live streaming video at use in contemporary resistance movements, particularly the work of CUTV during the Quebec Student Strike of 2012. With a brief comparison to the use of social media—and even live streaming—in the Occupy movement, this article demonstrates the differences, and sophistication, of live streaming video in the Quebec Spring. Specifically, this article seeks to understand the ways in which political actors and digital technologies form unique assemblages (in the Deleuzian sense), which can both operate as mechanisms of power as surveillance technologies for police forces or, if used carefully and critically, can open up nodes of counter-power, disrupting state surveillance, surveilling the police themselves, and providing the space for the construction of subjectivity on the part of political actors in the streets.  相似文献   

The dark side of social support: Understanding the role of social support,drinking behaviors and alcohol outlets for child physical abuse     

Bridget Freisthler  Megan R. Holmes  Jennifer Price Wolf 《Child abuse & neglect》2014

The purpose of this study is to examine how parental drinking behavior, drinking locations, alcohol outlet density, and types of social support (tangible, emotional, and social companionship) may place children at greater risk for physical abuse. Data on use of physical abuse, drinking behaviors, types of social support, social networks, and demographic information were collected via telephone interviews with 3,023 parent respondents in 50 cities in California. Data on alcohol outlet density were obtained by the California Department of Alcoholic Beverage Control. Multilevel Poisson models were used to analyze data for the drinking levels in the entire sample and dose-response drinking models for drinkers. Social companionship support was related to more frequent use of physical abuse. Having a higher percentage of social companionship support network living within the neighborhood was related to more frequent physical abuse in the full sample. This relationship was moderated by on-premise alcohol outlet density. With regards to drinking behaviors, drinking behaviors from ex-drinkers to frequent heavy drinkers used physically abusive parenting practices more often than lifetime abstainers. The dose-response models show that each additional drinking event at a bar or home/party was related to more frequent use of physical abuse. Practitioners working with parents who abuse their children should be aware that not all social support is beneficial. Findings build evidence that child maltreatment is influenced by the interaction between individual and ecological factors.  相似文献

Impact of social and dimensional comparisons on student's mathematical and English subject-interest at the beginning of secondary school     

《Learning and Instruction》2014

Recent studies have analyzed social and dimensional comparisons simultaneously in order to consider their impact on students' academic self-concept (e.g., Chiu, 2012). Thereby, social comparisons refer to comparisons with the achievement level of students' classmates, whereas dimensional comparisons comprise comparisons between students' individual achievements across different domains. This paper analyzes whether both achievement comparisons influence students' subject-interest in mathematics and English (as a first foreign language). The analyses are based on N = 1390 German fifth and sixth grade students who participated in the BiKS-8-14 longitudinal study. Using multi-level analyses, results indicate that students' competences influence their mathematical and English subject-interests, demonstrating the typical pattern of social and dimensional comparisons. Further, analyses reveal mediation effects by subject-specific grades and self-concepts. These findings also apply for the development of students' subject-interest from grade 5 to grade 6. Results are discussed with respect to their implications concerning theories of achievement comparisons and interest development.  相似文献   

Education and social change in post-conflict and post-disaster Aceh,Indonesia     

《International Journal of Educational Development》2014

The paper analyses the context in which education in Aceh acts strategically to advance an agenda of social transformation. Applying a cultural, political economy analytical framework, it identifies ways in which education is embedded in key cultural, political, economic and social struggles at present. They include: (1) the redistribution of educational opportunities and access; (2) ambiguous spaces for democratic representation in a decentralised educational structure; (3) competing notions of how diversity is acknowledged within Indonesia and Aceh Province; and (4) conflicted approaches to reconstruction following the 2004 tsunami and end of conflict in 2005.  相似文献
