Revista Espa?ola de Sanidad Penitenciaria , 2013,
Abstract: Objetivo: Analizar la difusión y el impacto de la investigación espa ola sobre Sanidad Penitenciaria en los últimos diez a os publicada en revistas científicas internacionales Material y método: Estudio descriptivo, longitudinal y retrospectivo de la producción científica. Se ha utilizado como fuente de información Medline-Pubmed. Se analizan aspectos bibliométricos de las revistas, los trabajos y los autores utilizando indicadores de Web of Science, Journal Citation Reports y los Essential Indicator. Se identifica la producción, las revistas, los autores y los temas de investigación. Resultados: Son 159 los trabajos publicados, lo que supone casi el 2% de la producción mundial en sanidad penitenciaria. El perfil de publicación mayoritario es en revistas internacionales de medio impacto en los JCR. La Revista Espa ola de Sanidad Penitenciaria, sin alcanzar protagonismo, es la más productiva (9.09%). Por autores, solo dos alcanzan un nivel medio alto con hasta 10 trabajos publicados en la década. El estudio de coautoría muestra una red muy tupida con 14 autores y distintas redes menores fragmentadas. Respecto de las citas, 6 son los trabajos que reciben 15 o más, siendo solo 2 los que podemos considerar altamente citados. Los temas de estudio presentan tres frentes: enfermedades infecciosas, drogas y problemas psiquiátrico-psicológicos. Conclusiones: La aportación espa ola a la investigación mundial en Sanidad Penitenciaria (1,9%) está próxima a otras disciplinas, aunque es ligeramente inferior (Medicina General representa el 3,05%, Salud Pública 2,38%, Psiquiatría 2,29%, Toxicología 2,46%). Se prevé que la Sanidad Penitenciaria remontará con la incorporación a Medline de su revista homónima y con el colectivo de autores que se ha incorporado a la corriente internacional. Esta incorporación no ha significado aun la integración en revistas de alto nivel y en citación. Las revistas utilizadas promedian un Factor de Impacto bajo (2,062) y son escasos los trabajos en revistas de primer nivel (Q1). Son pocos los trabajos con un promedio aceptable de citas en su área de conocimiento. El patrón de coautoría muestra aún un estado inmaduro de la investigación espa ola en Sanidad Penitenciaria. Objective: This paper sets out to analyze the dissemination and impact of Spanish research published in international scientific journals on Prison Health over the last decade. Material and methods: Descriptive, longitudinal and retrospective analysis of scientific output. We used the Medline-Pubmed database as an information resource. We focus on the bibliometric aspects of
Productivity and impact of Spanish researchers: reference thresholds within scientific areas
Jiménez-Contreras, Evaristo,Robinson-García, Nicolás,Cabezas-Clavijo, álvaro
Revista Espa?ola de Documentación Científica , 2011,
Abstract: Reference thresholds for the scientific production and impact of internationally visible Spanish research within the areas defined by the Spanish National Agency for Evaluation and Prospective (ANEP) are presented. These percentile reference tables are constructed from the population of researchers who applied for a project within Spain’s National R & D Plan 2007 (n = 3.356) and are to serve as benchmarks, permitting comparisons between researchers bibliometric behavior and mean performance in their respective scientific disciplines. Data relating to mean production, impact and visibility for each ANEP area are also presented. The internationalization of these areas between 2000 and 2006 is discussed, with special emphasis on the Social Sciences. Finally, we suggest funding agencies and research institutions use these reference thresholds as assessment tools in their selection processes. Se presentan umbrales de referencia de producción e impacto científico de la investigación espa ola con visibilidad internacional para las áreas definidas por la Agencia Nacional de Evaluación y Prospectiva (ANEP) en sus convocatorias. Tomando como población los solicitantes de proyectos del Plan Nacional de I + D 2007 (n= 3.356) se construyen tablas de referencia por percentiles que funcionan a modo de benchmarks, permitiendo efectuar comparaciones entre el comportamiento bibliométrico de un investigador y los registros de referencia en su área científica. Igualmente se ofrecen los datos de producción, impacto y visibilidad promedios para las áreas ANEP, y se discute el proceso de internacionalización de dichas áreas en el período 2000-2006, con una especial atención a las Ciencias Sociales. Finalmente, se sugiere el uso de umbrales de referencia como método de evaluación tanto para agencias financiadoras como para instituciones de investigación en sus procesos selectivos.

Computer Science , 2014, DOI: 10.3145/epi.2014.jul.03
Abstract: This paper analyzes Altmetric.com, one of the most important altmetric data providers currently used. We have analyzed a set of publications with DOI number indexed in the Web of Science during the period 2011-2013 and collected their data with the Altmetric API. 19% of the original set of papers was retrieved from Altmetric.com including some altmetric data. We identified 16 different social media sources from which Altmetric.com retrieves data. However five of them cover 95.5% of the total set. Twitter (87.1%) and Mendeley (64.8%) have the highest coverage. We conclude that Altmetric.com is a transparent, rich and accurate tool for altmetric data. Nevertheless, there are still potential limitations on its exhaustiveness as well as on the selection of social media sources that need further research.

Reviewers’ Ratings and Bibliometric Indicators: Hand in Hand When Assessing Over Research Proposals?
álvaro Cabezas-Clavijo, Nicolás Robinson-García, Manuel Escabias, Evaristo Jiménez-Contreras
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0068258
Abstract: Background The peer review system has been traditionally challenged due to its many limitations especially for allocating funding. Bibliometric indicators may well present themselves as a complement. Objective We analyze the relationship between peers’ ratings and bibliometric indicators for Spanish researchers in the 2007 National R&D Plan for 23 research fields. Methods and Materials We analyze peers’ ratings for 2333 applications. We also gathered principal investigators’ research output and impact and studied the differences between accepted and rejected applications. We used the Web of Science database and focused on the 2002-2006 period. First, we analyzed the distribution of granted and rejected proposals considering a given set of bibliometric indicators to test if there are significant differences. Then, we applied a multiple logistic regression analysis to determine if bibliometric indicators can explain by themselves the concession of grant proposals. Results 63.4% of the applications were funded. Bibliometric indicators for accepted proposals showed a better previous performance than for those rejected; however the correlation between peer review and bibliometric indicators is very heterogeneous among most areas. The logistic regression analysis showed that the main bibliometric indicators that explain the granting of research proposals in most cases are the output (number of published articles) and the number of papers published in journals that belong to the first quartile ranking of the Journal Citations Report. Discussion Bibliometric indicators predict the concession of grant proposals at least as well as peer ratings. Social Sciences and Education are the only areas where no relation was found, although this may be due to the limitations of the Web of Science’s coverage. These findings encourage the use of bibliometric indicators as a complement to peer review in most of the analyzed areas.
An insight into the importance of national university rankings in an international context: The case of the I-UGR Rankings of Spanish universities
Nicolás Robinson-García,Daniel Torres-Salinas,Emilio Delgado López-Cózar,Francisco Herrera
Computer Science , 2013,
Abstract: The great importance international rankings have achieved in the research policy arena warns against many threats consequence of the flaws and shortcomings these tools present. One of them has to do with the inability to accurately represent national university systems as their original purpose is only to rank world-class universities. Another one has to do with the lack of representativeness of universities' disciplinary profiles as they usually provide a unique table. Although some rankings offer a great coverage and others offer league tables by fields, no international ranking does both. In order to surpass such limitation from a research policy viewpoint, this paper analyzes the possibility of using national rankings in order to complement international rankings. For this, we analyze the Spanish university system as a study case presenting the I-UGR Rankings for Spanish universities by fields and subfields. Then, we compare their results with those obtained by the Shanghai Ranking, the QS Ranking, the Leiden Ranking and the NTU Ranking, as they all have basic common grounds which allow such comparison. We conclude that it is advisable to use national rankings in order to complement international rankings, however we observe that this must be done with certain caution as they differ on the methodology employed as well as on the construction of the fields.
Analyzing the citation characteristics of books: edited books, book series and types of publishers in the Book Citation Index
Daniel Torres-Salinas,Nicolás Robinson-García,álvaro Cabezas-Clavijo,Evaristo Jiménez-Contreras
Computer Science , 2013, DOI: 10.1007/s11192-013-1168-4
Abstract: This paper presents a first approach to analyzing the factors that determine the citation characteristics of books. For this we use the Thomson Reuters' Book Citation Index, a novel multidisciplinary database launched in 2010 which offers bibliometric data of books. We analyze three possible factors which are considered to affect the citation impact of books: the presence of editors, the inclusion in series and the type of publisher. Also, we focus on highly cited books to see if these factors may affect them as well. We considered as highly cited books, those in the top 5% of the most highly cited ones of the database. We define these three aspects and we present the results for four major scientific areas in order to identify field-based differences (Science, Engineering & Technology, Social Sciences and Arts & Humanities). Finally we conclude observing that differences were noted for edited books and types of publishers. Although books included in series showed higher impact in two areas.
Coverage, field specialization and impact of scientific publishers indexed in the 'Book Citation Index'
Daniel Torres-Salinas,Nicolás Robinson-García,J. M. Campanario,Emilio Delgado López-Cózar
Computer Science , 2013,
Abstract: Purpose: The aim of this study is to analyze the disciplinary coverage of the Thomson Reuters' Book Citation Index database focusing on publisher presence, impact and specialization. Design/Methodology/approach: We conduct a descriptive study in which we examine coverage by discipline, publisher distribution by field and country of publication, and publisher impact. For this the Thomson Reuters' Subject Categories were aggregated into 15 disciplines. Findings: 30% of the total share of this database belongs to the fields of Humanities and Social Sciences. Most of the disciplines are covered by very few publishers mainly from the UK and USA (75.05% of the books), in fact 33 publishers concentrate 90% of the whole share. Regarding publisher impact, 80.5% of the books and chapters remained uncited. Two serious errors were found in this database. Firstly, the Book Citation Index does not retrieve all citations for books and chapters. Secondly, book citations do not include citations to their chapters. Research limitations/implications: The Book Citation Index is still underdeveloped and has serious limitations which call into caution when using it for bibliometric purposes. Practical implications: The results obtained from this study warn against the use of this database for bibliometric purposes, but opens a new window of opportunities for covering long neglected areas such as Humanities and Social Sciences. The target audience of this study is librarians, bibliometricians, researchers, scientific publishers, prospective authors and evaluation agencies. Originality/Value: There are currently no studies analyzing in depth the coverage of this novel database which covers monographs.
Mapping Academic Institutions According to Their Journal Publication Profile: Spanish Universities as a Case Study
J. A. García,Rosa Rodríguez-Sánchez,J. Fdez-Valdivia,Nicolas Robinson-García,Daniel Torres-Salinas
Computer Science , 2013, DOI: 10.1002/asi.22735
Abstract: We introduce a novel methodology for mapping academic institutions based on their journal publication profiles. We believe that journals in which researchers from academic institutions publish their works can be considered as useful identifiers for representing the relationships between these institutions and establishing comparisons. However, when academic journals are used for research output representation, distinctions must be introduced between them, based on their value as institution descriptors. This leads us to the use of journal weights attached to the institution identifiers. Since a journal in which researchers from a large proportion of institutions published their papers may be a bad indicator of similarity between two academic institutions, it seems reasonable to weight it in accordance with how frequently researchers from different institutions published their papers in this journal. Cluster analysis can then be applied to group the academic institutions, and dendrograms can be provided to illustrate groups of institutions following agglomerative hierarchical clustering. In order to test this methodology, we use a sample of Spanish universities as a case study. We first map the study sample according to an institution's overall research output, then we use it for two scientific fields (Information and Communication Technologies, as well as Medicine and Pharmacology) as a means to demonstrate how our methodology can be applied, not only for analyzing institutions as a whole, but also in different disciplinary contexts.
