Google Scholar and Web of Science: Examining gender differences in citation coverage across five scientific disciplines     

Jens Peter Andersen  Mathias Wullum Nielsen 《Journal of Informetrics》2018,12(3):950-959

Many studies demonstrate differences in the coverage of citing publications in Google Scholar (GS) and Web of Science (WoS). Here, we examine to what extent citation data from the two databases reflect the scholarly impact of women and men differently. Our conjecture is that WoS carries an indirect gender bias in its selection criteria for citation sources that GS avoids due to criteria that are more inclusive. Using a sample of 1250 U.S. researchers in Sociology, Political Science, Economics, Cardiology and Chemistry, we examine gender differences in the average citation coverage of the two databases. We also calculate database-specific h-indices for all authors in the sample. In repeated simulations of hiring scenarios, we use these indices to examine whether women's appointment rates increase if hiring decisions rely on data from GS in lieu of WoS. We find no systematic gender differences in the citation coverage of the two databases. Further, our results indicate marginal to non-existing effects of database selection on women's success-rates in the simulations. In line with the existing literature, we find the citation coverage in WoS to be largest in Cardiology and Chemistry and smallest in Political Science and Sociology. The concordance between author-based h-indices measured by GS and WoS is largest for Chemistry followed by Cardiology, Political Science, Sociology and Economics.  相似文献   

Physics in upper secondary schools in Denmark     

H. Nielsen  P. V. Thomsen 《International Journal of Science Education》2013,35(2):189-202

This article is the third in a series reporting on the changes in attitudes and interests‐‐mainly with respect to physics‐of several hundred students as they proceed through the Danish upper secondary school (Gymnasium). It concentrates on the results of the final investigation which took place shortly before the students leave the school.  相似文献   

Television: The performance of nonresident students in the “economics U$A” telecourse     

Paul W. Grimes  Joyce E. Nielsen  James F. Niss 《The American journal of distance education》2013,27(2):36-43

Abstract

Correspondence study represents the first and most persistent distance education format in American universities. Later called independent study, it enabled universities to disseminate instruction far beyond their campuses. Yet, national‐level leadership provided by the National University Continuing Education Association (NUEA) and its divisions has been relatively restrained. In contrast, leadership in the private correspondence school sector has been assertive, and sometimes even aggressive. The NUEA and its members shunned this approach, choosing instead to lead by persuasion and example. The NUEA developed standards of practice concerned primarily with replicating on‐campus teaching styles and values, rather than the promotion of distance education. With the abolition of its division structure, the NUEA's successor, the University Continuing Education Association (UCEA), has opted out of a leadership role in independent study. This paper concludes that the NUEA's initial attempt at leadership in distance education— while reasoned and principled—contained flaws that made failure inevitable.  相似文献   

The endless spiral     

Henry Nielsen 《Science & Education》1993,2(2):169-181

A Danish textbook on the history of technology,Skruen uden ende — Den vestlige teknologis historie (The Endless Spiral: A History of Western Technology), was published in 1990. In the present article, one of the authors presents some of the background to this event and puts the work into historical perspective by describing a number of different traditions for writing textbooks on the history of technology. Next follows a discussion of why history of technology ought to be an important ingredient in upper secondary education and why only the contextualist tradition — inspired by the rapidly developing school of research centered around the journalTechnology & Culture — offers any real hope for providing meaningful teaching materials on history of technology. The paper ends with a brief outline of the textbook's contents, with special emphasis on one of its several case studies describing the development of certain mainstream technologies in the context of the scientific, economic, social and cultural developments existing when the particular technology came into being.  相似文献   

The importance of morphemic awareness to reading achievement and the potential of signing morphemes to supporting reading development     

Nielsen DC  Luetke B  Stryker DS 《Journal of deaf studies and deaf education》2011,16(3):275-288

The ability to access and understand the meaning of multi-morphemic words is essential for age-appropriate literacy growth as well as for achievement in other participants, such as science and social studies, which are so print-dependent. This paper provides a theoretical basis for focusing on the morphology of English when teaching students who are deaf or hard of hearing to read through a review of the literature on the role of morphology in reading for both hearing students and those with a hearing loss. In addition, the authors review the empirical literature on Signing Exact English (SEE), a system of signing English constructed in which the morphology of words is made visible to children who might not be able to hear them. The authors propose that students' use of SEE can provide a bridge to developing the morphemic awareness so necessary for age-appropriate reading development and achievement.  相似文献   

Social,emotional and intercultural competencies: a literature review with a particular focus on the school staff     

Birgitte Lund Nielsen  Hilmar Dyrborg Laursen  Lise Andersen Reol  Helle Jensen  Ana Kozina  Masa Vidmar 《欧洲师范教育杂志》2019,42(3):410-428

Framed by the EU-project Hand in Hand focusing on Social, Emotional and Intercultural (SEI) competencies among students and school staff the paper discusses implementation and professional competencies based on a literature review. Five themes were identified: 1) Intercultural/transcultural competency is not often referred to in the same research as social-emotional learning, though socio-emotional aspects appear to be `in the core´, 2) it is crucial to be aware of agency among school staff in a SEI-implementation, 3) successful implementation is about more than the activities in the specific program, it is rather about elements in synergy and professional learning over time, 4) the subtle balance between adaptation and fidelity might best be addressed in an adaptive curriculum emphasizing active ingredients, and 5) this is a field with many intervention studies, but it is urgent to consider if the psychometric measures are sufficiently sensitive to catch the subtle changes related to SEI-competencies.  相似文献

‘Pervy role-play and such’: girls' experiences of sexual messaging online     

Silja Nielsen  Sanna Spisak 《Sex education》2015,15(5):472-485

Sexting is one of the recurring causes of concern in public discussion of young people and network media. This paper builds on findings from a survey with 1269 Finnish female respondents aged 11–18 conducted using a popular online community for girls on their experiences of and views on online messages concerning sex and sexuality. Sixty-five per cent of respondents had received messages related to sex from either adults or minors while 20% had also sent such messages themselves. The paper asks how girls experience and make sense of sexual messaging and what motivates them to engage in such interactions. Specific attention is paid to the distinction between unwanted and wanted messages. While messages from unknown people identified as adult were often discussed as unpleasant or ‘creepy’, sexual messaging, role-play, cybersex experiments and discussions related to sex among peers were defined as fun and pleasurable. Girls display notable resilience and describe coping strategies connected to unwanted messaging but equally frame sexual messaging and role-play as issues of choice motivated by curiosity and pleasure. The paper addresses sexual messaging as a form of sexual play and learning, and argues for the importance of contextual analysis in understanding its forms and potentialities.  相似文献   

User community vs. producer innovation development efficiency: A first empirical study     

Christoph Hienerth  Eric von Hippel  Morten Berg Jensen 《Research Policy》2014

In this paper we report upon a first empirical exploration of the relative efficiency of innovation development by product users vs. product producers. In a study of over 50 years of product innovation in the whitewater kayaking field, we find users in aggregate were approximately 3× more efficient at developing important kayaking product innovations than were producers in aggregate. We speculate that this result is driven by what we term “efficiencies of scope” in problem-solving. These can favor an aggregation of many user innovators, each spending a little, over fewer producer innovators benefitting from higher economies of scale in product development. We also note that the present study explores only one initial point on what is likely to be a complex efficiency landscape.  相似文献
