The impact of data source on the ranking of computer scientists based on citation indicators: a comparison of web of science and ScopusZhang, Li January 2014 (has links)
Conference proceedings represent a large part of the literature in computer science. Two Conference Proceedings Citation Index databases were merged with Web of Science in 2008, but very few studies have been conducted to evaluate the effect of that merger of databases on citation indicators in computer science in comparison to other databases. This study explores whether or not the addition of the Conference Proceedings Citation Indexes to Web of Science has changed the citation analysis results when compared to Scopus. It compares the citation data of 25 randomly selected computer science faculty in Canadian universities in Web of Science (with Conference Proceedings Citation Indexes) and Scopus. The results show that Scopus retrieved considerably more publications including conference proceedings and journal articles. Scopus also generated higher citation counts and h-index than Web of Science in this field, though relative citation rankings from the two databases were similar. It is suggested that either database could be used if a relative ranking is sought. If the purpose is to find a more complete or higher value of citation counting or h-index, Scopus is preferable. It should be noted that no matter which source is used, citation analysis as a tool for research performance assessment must be constructed and applied with caution because of its technological and methodological limitations

Normalização e indicadores de impacto: implicações entre os periódicos brasileiros indexados na SciELO e WoS / Normalization and impact indicators: implications among Brazilian journals indexed in SciELO and WoSPaula, Angelica de Souza Alves de 13 December 2018 (has links)
Além de ser um filtro para selecionar e legitimar o caráter científico do que é publicado, a citação é um meio de distribuir créditos e reconhecimento. Com o surgimento dos índices de citação, novas possibilidades se abriram para avaliação de produção científica por meio de indicadores. Dentre eles, o Fator de Impacto é o mais utilizado para aferir o impacto de um periódico, sendo calculado em termos do número de citações que tal periódico alcança, tomando como fonte de informação as referências de todos os periódicos catalogados numa base de dados. Neste contexto, a normalização também é primordial, por garantir a transferência da informação científica em padrão específico, sendo assim responsável direta da qualidade dos estudos bibliométricos, e consequentemente, na avaliação da produção científica. O objetivo geral do trabalho foi contribuir com a discussão sobre a importância da normalização no uso de indicadores para avaliação de periódicos científicos. Os objetivos específicos foram: a) analisar a distribuição das referências bibliográficas de periódicos ao longo do tempo, no que diz respeito ao nível de normalização das referências e seu impacto na análise de citações, considerando ainda a obsolescência e tipologia documental; b) realizar análise comparativa entre áreas. Através da análise das citações feitas, no período de 2011 a 2015, pelos periódicos brasileiros indexados na SciELO e WoS, foi possível verificar a o aumento de citações a periódicos ante outros tipos documentais, constatar o cumprimento das recomendações quanto ao uso de referências atualizadas e utilização cada vez menor de autocitação. No entanto, ainda que indexados em bases criteriosas e rigorosas e possuírem bibliotecários em suas equipes, a taxa de erros de normalização ainda é pronunciada. / In addition to being a filter to select and legitimize the scientific character of what is published, citation is a means of distributing credits and recognition. With the appearance of citation indexes, new possibilities were opened for the evaluation of scientific production through indicators. Among them, the Impact Factor is the most used to gauge the impact of a periodical, being calculated in terms of the number of citations that periodic reaches, taking as reference information the references of all the periodicals cataloged in a database. In this context, standardization is also paramount, since it guarantees the transfer of scientific information in a specific pattern, being therefore directly responsible for the quality of bibliometric studies, and consequently, for the evaluation of scientific production. The general objective of the study was to contribute to the discussion about the importance of standardization in the use of indicators for the evaluation of scientific journals. The specific objectives were: a) to analyze the distribution of bibliographical references of periodicals over time, regarding the level of normalization of references and their impact in the analysis of citations, considering also the obsolescence and typology of documents; b) perform a comparative analysis between areas. Through the analysis of the citations made in the period from 2011 to 2015 by the Brazilian journals indexed in SciELO and WoS, it was possible to verify the increase of citations to periodicals compared to other documentary types, to verify compliance with the recommendations regarding the use of updated references and use less and less self-citing. However, although indexed on a strict and rigorous basis and have librarians in their teams, the error rate of normalization is still pronounced.

Previous issue date: 2013-02-21 / Financiadora de Estudos e Projetos / In the last two decades, the traditional knowledge has been the subject of intense discussion. This subject is studied by researchers from various areas of knowledge, generating a large number of documents, such as, journal articles, theses and dissertations. A way to evaluate the science on this subject is analyzing these documents. In this dissertation, through quantitative, descriptive and exploratory methods, it has been conducted two bibliometric analyses. The first regards the scientific production of theses and dissertations with thematic related to traditional knowledge, defended in Brazilian universities and indexed in the CAPES theses Database. The second analysis, carried out on the Web of Science database with articles about the theme Traditional Knowledge , encompassed three searches: (1) articles written by Brazilian authors; (2) international scientific production about Brazil; (3) global production of scientific documents. The bibliometric analysis pointed out that the Federal University of Santa Catarina is the Brazilian institution that has published most of the theses and dissertations on the subject, spotting the Graduate Program in Agroecosystems. Environmental studies were the ones that stood out the most, mainly the areas Ecology and Agronomy. These results suggest the treatment of traditional knowledge as a thematic subordinate to its ecological dimension. / Nas duas últimas décadas, o conhecimento tradicional tem sido objeto de intensa discussão. É estudado por pesquisadores de diversas áreas do conhecimento, gerando um grande número de documentos, tais como: artigos científicos, teses e dissertações. Um modo de avaliar a ciência relativa a este assunto é analisar estes documentos. Nesta dissertação, por meio de métodos quantitativos, descritivos e exploratórios, foram realizadas duas análises bibliométricas. A primeira refere-se à produção científica de teses e dissertações, com temáticas relacionadas ao conhecimento tradicional, defendidas nas universidades brasileiras e indexadas no Banco de Teses da CAPES. A segunda, desenvolvida na base de dados internacional Web of Science com artigos sobre o tema Conhecimento Tradicional , envolveu três buscas: (1) artigos produzidos por brasileiros; (2) produções científicas internacionais sobre o Brasil; (3) produção mundial de documentos. A análise revelou que a Universidade Federal de Santa Catarina é a instituição brasileira que mais publicou teses e dissertações sobre o tema, destacando-se o Programa de Pós-Graduação em Agroecossistemas. Os estudos ligados ao meio ambiente foram os que mais se sobressaíram, principalmente nas áreas de Ecologia e Agronomia. Estes resultados evidenciam o tratamento do conhecimento tradicional como uma temática subordinada à sua dimensão ecológica.

Akademiska söktjänster : En jämförande studie av Google Scholar, MEDLINE och Web of Science / Academic search engines : A comparative study of Google Scholar, MEDLINE and Web of ScienceElfström, Isabelle, Persson, Sandra January 2012 (has links)
The purpose of this paper is to compare the three search engines Web of Science, Google Scholar and MEDLINE in regards of recovery efficiency and the overlap of relevant documents when it comes to information searching for academic purposes. Furthermore, it raises the question whether freely available search engines and licensed search engines are interchangeable with each other. The empirical data in this study were collected through searches conducted in the three search engines Web of Science, Google Scholar and MEDLINE. Twenty search queries were used and the first twenty retrieved documents for each query were examined for relevance using previously designed criteria. The documents were scored by a binary relevancy scale and thereafter a precision value for each search engine was calculated. The overlap of retrieved relevant document in all three search engines were also calculated using Jaccard’s Index. The results of this study showed that Web of Science was the search engine that had the highest precision value, 0.346 and that the largest overlap was between MEDLINE and Web of Science with a value of 0.112. / Program: Bibliotekarie

El uso de la gamificación ha ingresado con fuerza en todos los niveles del ámbito educativo. Este artículo analiza el comportamiento de la producción científica sobre gamificación aplicada a la educación mediante indicadores bibliométricos y mapas de visualización. Los datos fueron extraídos del Science Citation Index Expanded (SCIE), Social Sciences Citation Index (SSCI) y Arts & Humanities Citation Index (A&HCI) de Web of Science (2012-2018) en dos etapas. En la primera, se analizó la dinámica de la producción científica sobre gamificación recuperando 807 registros. En la segunda etapa, la búsqueda se restringió a las categorías vinculadas con temas de educación, quedando 153 documentos. En los resultados se demuestra que la producción científica se incrementa cada año, asimismo se identificaron las revistas más productivas en la temática. Mediante el análisis de cocitación de autores se identificó la influencia intelectual de la producción sobre gamificación detectando a los autores y comunidades invisibles más representativas. Por último, mediante el mapa de superposición de palabras clave, se evidenció que la gamificación aplicada a la educación toma un enfoque cada vez más tecnológico e innovador. / The use of gamification has entered strongly into all le-vels of education. This article analyzes the behavior of scientific production on gamification applied to education through bibliometric indicators and visualization maps. The data were extracted from the Science Citation Index Expanded (SCIE), Social Sciences Citation Index (SSCI) and Arts & Humanities Citation Index (A&HCI) of Web of Science (2012-2018) in two stages. In the first one, it was analyzed the dynamics of scientific production on gami-fication recovering 807 records. In the second stage, the search was restricted to the categories related to educa-tion issues, leaving 153 documents.

A study of risks of threats and violence toward hospital staff in relation to patient access to electronic medical recordsÅkerstedt, Ulrika January 2015 (has links)
In 2012, the county of Uppland in Sweden launched a service granting patients online access to their electronic medical record (EMR), including the list of staff who have logged into the record (the “log list”). Patients seem predominantly positive to this service whereas many professionals, physicians specifically, have expressed concerns about, for example, increased risks of threats and violence towards healthcare staff. One year after launch the present study was conducted to examine whether staff whose patients had gained access to online EMRs experienced greater risks of threats and violence, and were exposed to more threats and violence, than those whose patients had not yet gained access. The extent to which professional role, gender, work experience and staff attitudes to the service were important factors was also examined. A total of 174 professionals at Uppsala University Hospital responded to a web survey (35% response rate). 83 represented the emergency department, whose patients had online EMR access, and 91 represented the psychiatric department, whose patients had not. 40% of all participating professionals, emergency physicians and psychiatric staff specifically, believed that risks of threats and violence increase after launch. The results did not, however, support a correlation between patient access to online EMRs and more incidents of threats and violence, and only one respondent reported that patient access had played any significant negative role in relation to an incident. These and other results may prove useful as the online EMR service is now being launched in other Swedish counties as well. / År 2012 infördes inom Uppsala läns landsting en tjänst som ger patienter tillgång till sin journal via nätet, inklusive listan över personal som loggat in i journalen. Patienter har visat sig vara övervägande positiva till tjänsten, medan många vårdgivare, speciellt läkare, har uttryckt farhågor gällandes, till exempel, ökad risk för hot och våld mot vårdpersonal. Ett år efter införandet genomfördes denna enkätstudie med syfte att undersöka om sjukvårdspersonal vars patienter fått tillgång till journal via nätet upplever högre grad av risk för hot och våld samt om de i realiteten är mer utsatta för hot och våld än dem vars patienter inte fått denna tillgång. Även betydelsen av yrke, kön, arbetserfarenhet samt generell attityd till journal via nätet undersöktes i relation till hot och våldsrisker respektive utsatthet för våld. En webundersökning besvarades av 174 anställda vid Akademiska sjukhuset i Uppsala (svarsfrekvens 35 %). 83 representerade den öppna akutvårdsmottagningen, vars patienter hade tillgång till journal via nätet, och 91 representerade de slutenvårdspsykiatriska avdelningarna, vars patienter inte hade denna tillgång. 40 % av respondenterna, speciellt akutvårdsläkare och psykiatrivårdspersonal, trodde att riskerna för hot och våld ökar vid införande av journal via nätet. Resultaten påvisade dock inte någon korrelation mellan patienttillgång till journal via nätet och förekomst av hot- och våldsincidenter och endast en respondent svarade att patienttillgång spelat en betydande negativ roll i relation till en incident. Dessa och andra resultat i studien kan vara av betydelse nu när införanden av journal via nätet sprids även till andra landsting i Sverige.
