Objective Increase in population's longevity has led to considerable efforts worldwide on physical therapy aging research. The aim of this study is to identify which are the main scientific journals, as well as the most productive authors, institutions and keywords related to the journals, that have published about physical therapy and aging. Methods Original articles published from 1990 to 2014 were retrieved from the bibliographic database Science Citation Index Expanded of Web of Science Core Collection. After standardization of the bibliographic information, a series of bibliometric indicators was obtained regarding authors, institutions, citation and keywords of the core journals using bibliometric software. The PAJEK network analysis program was used for graphic representation. Results A total of 2,237 original articles are included in this analysis. The number of identified journals is 573, with an average growth of publishing journals throughout the studied period of 9.41%. Bradford's distribution shows 12 core journals, out of which 41.67% have published constantly all throughout the 25-year period, being the most productive one Physical Therapy. Fritz, Julie M is the most productive author, and University of Sydney the most productive institution. The keyword exercise is used in an outstanding way. Conclusions The productivity trends provided an indication of the greater scientific interest of physical therapy in aging as a line of research. Collectively, the data indicated that physical therapy-specific journals are being consolidated but non-specific are still a significant research source, and that a fundamental element of their research includes exercise and movement.

Compartir en abierto y facilitar el acceso a los datos de investigación, su uso y reutilización no son prácticas habituales entre los investigadores, a excepción de determinadas disciplinas, como la meteorología, la genética o la astronomía. Las políticas de las instituciones, de algunas editoriales y de las agencias que financian la investigación han provocado que esta cultura de compartir y gestionar los datos de investigación cobre una especial relevancia. Sin embargo, existen barreras como el miedo de los investigadores a que les quiten la primicia y a ser copiados, a que se haga un mal uso de sus datos, a perder el control o infringir la legislación sobre la propiedad intelectual, con las que se enfrenta la comunidad científica para poder hacer que sus datos sean localizables, accesibles, interoperables y reutilizables (datos FAIR). En este trabajo se han analizado los pros y los contras de compartir y reutilizar los datos, basándonos en trabajos previos que han permitido vislumbrar hábitos y opiniones de los investigadores a este respecto., Research data sharing, data reuse and facilitating access to research data are not common researchers’ practices, except in certain disciplines, such as Meteorology, Genetics or Astronomy. Institutional, publishers’ and funders’ policies have made the culture of sharing and managing research data particularly relevant. However, the threat of being scooped, the fear to the misuse of their data, to lose control over their data, or the fear to infringe the legislation on intellectual property, are barriers that scientific community faces when trying to make their data findable, accessible, interoperable and reusable (FAIR data). In this work, we have analyzed the pros and cons of sharing and reusing data, based on previous works in the literature that have allowed us to perceive researchers’ habits and perceptions in this regard.

Purpose – The purpose of this paper is to analyze the disciplines and thematic study of scientific production in police training over the period 1988-2012. Design/methodology/approach – Introduction and homogenization of keywords and assigning of descriptors to documents, thematic categorization of journals and, analysis of indicators of productivity and relationship of descriptors and thematic areas has been the used methodology. Findings – Totally, 59 different descriptors of a total of 585 assigned to the 182 articles that were published in 95 journals belonging into 20 different subject areas have been identified. The most frequent descriptors are “skills,” “management development” and “violence” and the main thematic areas have been “Criminology and Penology” and “Psychology”. Totally, 47 relationships between 30 descriptors in more than two works, 35 relationships between 20 thematic areas and, 78 relationships between 43 descriptors and eight subject areas in more than two articles have been identified. Originality/value – Characterize the disciplines and thematic of study of the articles and journals in the scientific production on police training, as well as to identify the relationships between descriptors, subject areas and among these.

Resumen Introduccion y objetivos La Sociedad Espanola de Cardiologia celebra anualmente un congreso nacional en el que se presentan numerosas comunicaciones. Sin embargo, se desconoce si posteriormente se publican como articulos y en que revistas. Nuestro objetivo es identificar el grado de publicacion de estas comunicaciones y analizar sus caracteristicas bibliometricas. Metodos Se selecciono aleatoriamente una muestra de 300 comunicaciones presentadas de forma oral durante los congresos de 2002, 2005 y 2008. La identificacion de los trabajos publicados se realizo mediante busqueda en las bases de datos Science Citation Index-Expanded, Scopus , Indice Medico Espanol e Indice Bibliografico Espanol en Ciencias de la Salud. Resultados De las 300 comunicaciones, 115 derivaron en 147 articulos publicados (el 38,33% de publicacion). El congreso que obtuvo un mayor indice de publicaciones fue el de 2005 (43%). El mayor numero correspondio al area de cardiologia pediatrica/cardiopatias congenitas (58,8%). El mayor porcentaje de trabajos se publico a los 2 anos de la celebracion del congreso (30,61%). Los articulos se han publicado en 57 revistas, de las que han pblicado el mayor numero de articulos Revista Espanola de Cardiologia (n = 55; 37,41%) y European Heart Journal (n = 8; 5,44%). Conclusiones El alto porcentaje de articulos publicados en revistas de la mitad superior de la categoria Cardiac and Cardiovascular System del Journal Citation Reports (83%) se puede considerar un indicador objetivo de la calidad de las comunicaciones presentadas en estos congresos. Que mas de un 60% de las comunicaciones no se publique priva a la comunidad cientifica de unos resultados potencialmente interesantes.

Resumen Introduccion y objetivos La Sociedad Espanola de Cardiologia convoca anualmente becas para financiar proyectos de investigacion en el campo de las enfermedades cardiovasculares. Nuestro objetivo es identificar la repercusion de estas inversiones durante el periodo 2000-2006 a partir de los articulos derivados de las becas y publicados en revistas cientificas. Metodos Utilizando los datos de identificacion de cada proyecto como terminos de busqueda, se recuperaron todos los articulos derivados de estas becas en las bases de datos del Indice Medico Espanol, el Indice Bibliografico Espanol en Ciencias de la Salud, el Science Citation Index-Expanded y Scopus. Los articulos se sometieron a un analisis estadistico descriptivo en relacion con la tipologia de las becas, la evolucion anual de su numero y de su importe, el sexo y las instituciones de los becados. Resultados Se concedieron 207 becas con un importe total de 3.270.877 € y una dotacion media anual de 467.268 €. De ellas, 123 (59,42%) aportaron publicaciones derivadas. El promedio de articulos publicados por beca concedida ha sido de 1,12, y de 1,9 si se tiene en cuenta unicamente las becas que dieron lugar a publicaciones. Conclusiones Durante el periodo 2000-2006, la Sociedad Espanola de Cardiologia/Fundacion Espanola del Corazon destino casi 500.000 € anuales a financiar becas de investigacion y asi contribuir a luchar contra las enfermedades cardiovasculares. Casi el 60% de las becas han aportado publicaciones derivadas, 231 articulos. El 73% de los articulos se publicaron en revistas extranjeras y el 91,34%, en revistas espanolas o extranjeras con factor de impacto en el Journal Citation Reports.

Evaluating the Information Architecture in an already deployed website is not an easy task. Most evaluation techniques are focused on examining system usability, but this is not the only factor that influences IA. The main technique that deals with IA in already deployed web environments is the Navigation Stress Test (NST). A new methodology makes this technique more informative by taking NST beyond simple notation on paper. This work proposes the use of NST combined with other usability testing techniques such as Thinking Aloud and a usability questionnaire. Eye tracking also has been used to supplement the information obtained from applied techniques. This new methodology has been tested by analyzing a series of websites belonging to Spanish public university libraries. The results of this study show the validity of the approach used, as well as the value that this approach and the use of Eye tracking bring to the analysis of IA compared to traditional NST

This study analyses the bibliometric characteristics of the presentations at the 5th, 8th and 10th Conferences of the International Society for Scientometrics and Informetrics, which were subsequently published in peer-reviewed journals covered by the Science Citation Index, Social Science Citation Index and LISA databases. 31.7% of all the papers presented at the three conferences were published. Scientometrics was the journal that published the highest proportions. A low rate of publication deprives researchers of potentially interesting results and points up the role of the ISSI Conference proceedings as a primary source of information.

The main fields of research in Library Science and Documentation are identified by quantifying the frequency of appearance and the analysis of co-occurrence of the descriptors assigned to 11,273 indexed works in the Library and Information Science Abstracts (LISA) database for the 2004–2005 period. The analysis made has enabled three major core research areas to be identified: World Wide Web, Libraries and Education. There are a further 12 areas of research with specific development, one connected with the library sphere and another 11 connected with the World Wide Web and Internet: Networks, Computer Security, Information technologies, Electronic Resources, Electronic Publications, Bibliometrics, Electronic Commerce, Computer applications, Medicine, Searches and Online Information retrieval.

The aim of this paper is to present the bibliometric indicators for Revista Espanola de Cardiologia that were obtained from the “Potential impact factor of Spanish medical journals in 2001” study financed by the Spanish Ministerio de Educacion, Cultura y Deporte. Citations to Revista Espanola de Cardiologia , its national and international impact factor, and its immediacy index were calculated with methods similar to those used by the Institute for Scientific Information. National indicators were based only on citations from 87 Spanish journals considered source journals, whereas international indicators were calculated on the basis of citations from both national journals and foreign source journals in the Science Citation Index. Revista Espanola de Cardiologia obtained a national impact factor of 0.719 and an international impact factor of 0.837, placing it at the head of the ranking of Spanish medical journals.

Fundamento y objetivo En 2001 solo 13 revistas medicas espanolas estaban incluidas en elJournal Citation Reports, por lo que se desconoce el factor de impacto (FI) del resto de revistasespanolas. El objetivo es determinar el FI de las principales revistas medicas espanolas, tenien-do en cuenta las citas procedentes de las revistas no incluidas en la cobertura del Science Ci-tation Index Pacientes y metodo Se analizaron las referencias bibliograficas de 1999, 2000 y 2001 de losarticulos citables publicados en 2001 en una seleccion de 87 revistas medicas espanolas in-cluidas en la base de datos nacional Indice Medico Espanol y en alguna otra base de datos in-ternacional. Se calcularon el numero de citas, el FI y el indice de inmediatez de cada revista Resultados Se analizaron 5.388 referencias bibliograficas procedentes de 74 revistas fuente ocitadoras no incluidas en el Journal Citation Reports y se identificaron las revistas citadas. Aestas citas se anadieron las que cada revista habia recibido en Science Citation Index. La revis-ta mas citada fue MEDICINACLINICA, con 768 citas, y las de mayor FI fueron Histology and His-topathology(FI = 1,866), International Journal of Developmental Biology(FI = 1,654) y MEDICI-NACLINICA(FI = 1,125) Conclusiones Este trabajo ha permitido obtener el FI de 87 revistas medicas espanolas y con-firma los resultados obtenidos en trabajos anteriores que mostraron el liderazgo de MEDICINACLINICAen la medicina espanola. Las revistas publicadas en ingles han recibido pocas citas delresto de las espanolas. La falta de impacto en algunas revistas no estanecesariamente relacio-nada con su falta de calidad, merito o relevancia

El objetivo de este trabajo es presentar los indicadores bibliometricos de Revista Espanola de Cardiologia obtenidos del estudio «Factor de impacto potencial de las revistas medicas espanolas en 2001», financiado por el Ministerio de Educacion Cultura y Deporte espanol. Siguiendo una metodologia similar a la que emplea el Institute for Scientific Information, se han obtenido las citas de Revista Espanola de Cardiologia y su factor de impacto e indice de inmediatez nacionales e internacionales. Los indicadores nacionales tienen en cuenta unicamente las citas procedentes de 87 revistas espanolas seleccionadas como fuentes, mientras que para el calculo de los indicadores internacionales se han sumado a las citas anteriores las que proceden de las revistas fuente extranjeras del Science Citation Index. Revista Espanola de Cardiologia ha obtenido un factor de impacto nacional de 0,719 y un factor de impacto internacional de 0,837, lo que la situa en posiciones de liderazgo en la medicina espanola

Introduction and objectives The Spanish Society of Cardiology holds an annual national meeting with a large number of presentations but the number of full-text publications resulting from these presentations and the journals accepting these manuscripts is unknown. This study aimed to identify the full-text publication rate of accepted abstracts and to analyze the bibliometric features of subsequent publications. Methods We randomly selected a sample of 300 oral presentations at the meetings of the Spanish Society of Cardiology in 2002, 2005 and 2008. Subsequent publications were identified through the Science Citation Index-Expanded, Scopus, Indice Medico Espanol , and Indice Bibliografico Espanol en Ciencias de la Salud . Results Of 300 abstracts, 115 resulted in 147 full publications, representing a publication rate of 38.33%. The meeting with the highest publication rate (43%) was held in 2005. The subject category with the highest number of publications was Pediatric Cardiology/Congenital Heart Disease (58.8%). Time to full publication was usually 2 years (30.61%). Articles were published in 57 journals. The journals publishing the highest number of articles were Revista Espanola de Cardiologia (n=55; 37.41%) and the European Heart Journal (n=8; 5.44%) . Conclusions The high percentage of articles published in the upper half of journals listed in Journal Citation Reports under the category of cardiac and cardiovascular system (83%) can be taken as an objective quality indicator of the results presented at these meetings. However, more than 60% of the abstracts did not result in full publications, thus depriving the scientific community of potentially interesting results.

The analysis of productivity and disciplinary collaboration patterns for Spanish published scientific research in the field of Substance Abuse (2001-2005).From institutional affiliations we identified and quantified disciplinary participation in papers indexed in the IME/Indice Medico Español, ISOC/Indice Español de Ciencias Sociales y Humanidades, SCI-Expanded/Science Citation Index-Expanded and SSCI/Social Sciences Citation Index databases.A total of 31 disciplines and specialities were identified in ISOC, with 8.6% of documents in collaboration between them; 55 medical specialities were identified in IME, with 10.89% of documents in collaboration between them; and 62 specialities were identified in SCI-Expanded, with 41.68% of documents in collaboration between them.a) Substance Abuse, Psychology, Psychiatry, Epidemiology-Preventive Medicine and Public Health and Pharmacology are the disciplines and specialities that present the highest productivity. To these can be added, in papers published in foreign journals, specialities such as Biochemistry-Molecular Biology, Neurology and Neuroscience; b) Papers published in Spanish journals indexed in SCI-Expanded and in papers published in foreign journals present much higher collaboration indexes between disciplines and specialities; c) The main collaborations between specialities are those between Substance Abuse, Psychiatry and Psychology. To these can be added, in the case of journals indexed in SCI-Expanded, those between these specialities and Pharmacology, Neurology and Neuroscience.

Concern for encouraging gender equality makes it one of the high priority spheres of action for governments and organisations responsible for instigating scientific policies, with particular importance being placed on including the gender variable in evaluative analyses of scientific and technological activity. A comparative study was made, broken down by gender, of the scientific output of Spanish researchers with a high production in the field of substance abuse.We identified the gender of 338 authors who had published more than four different articles during the period from 1999-2004 and which were indexed in the IME/Indice Médico Español and the SCI/Science Citation Index databases, making a comparative analysis of their output and collaboration patterns, based on the gender variable.In the area of substance abuse, of those with the highest output (9 papers), 70% were men compared with 30% women. Among the average producers (5-9 papers), 57% of the authors identified were men and 43% women. Statistically significant differences were observed between men and women with the highest output with regard to the number of published works and those with whom they had collaborated.There is no gender equality in the area of substance abuse, particularly when considering the top researchers. It is essential to make in-depth studies that evaluate scientific output, broken down by gender, in order to adopt the necessary corrective measures to eliminate the disparity between men and women.

Objective Reproductive biology is a highly productive area. By analyzing papers published in the major journals in the period 2003–2005, the collaborative patterns were characterized. Design Original research papers published in 2004 in the journals included in the first quartile of the category "Reproductive Biology" of the Journal Citation Reports (2005) were selected. A bibliometric analysis was carried out with the information obtained, thus building up the networks of coauthorship and institutional collaboration. Result(s) A total of 4,702 papers were analyzed, 96.75% signed in collaboration by two or more authors, the authors per paper index being 5.24; 73.73% of the papers were collaborations between institutions. The U.S.A. and the U.K. headed the absolute productivity ranking in number of papers, and adapting the data with respect to the population, Israel, Australia, and other European countries, such as Finland, Belgium, Sweden, and The Netherlands, had notable contributions. Conclusion(s) We identified the networks of authors who publish in the journals with the greatest impact factor. Only some of the most productive institutions have consolidated collaborative relationships with other institutions. We identified the scientific "isolation" of some countries which, although their productivity is high, have a small number of international collaborations.

The aim of this paper is to present the bibliometric indicators for Revista Española de Cardiologíathat were obtained from the "Potential impact factor of Spanish medical journals in 2001" study financed by the Spanish Ministerio de Educacion, Cultura y Deporte. Citations to Revista Española de Cardiología, its national and international impact factor, and its immediacy index were calculated with methods similar to those used by the Institute for Scientific Information. National indicators were based only on citations from 87 Spanish journals considered source journals, whereas international indicators were calculated on the basis of citations from both national journals and foreign source journals in the Science Citation Index. Revista Española de Cardiologíaobtained a national impact factor of 0.719 and an international impact factor of 0.837, placing it at the head of the ranking of Spanish medical journals.

The 2001 edition of the Journal Citation Reports (JCR) includes only 13 Spanish medical journals. The impact factor (IF) of the rest of Spanish medical journals is unknown. The aim of this study is to determine the IF of the main Spanish medical journals, taking also into account the references from journals not covered by the SCI.A set of 87 Spanish medical journals was selected from the national database IME and other international databases. All citable articles published in these journals in 2001 were analyzed, extracting their bibliographic references to articles published in 1999, 2000 and 2001. The indicators obtained for each journal were the number of cites, the IF and the immediacy index.Among the 87 source journals, 74 were not included in the JCR. From them, 5,388 bibliographic references were examined, identifying the journals cited. Final indicators were obtained adding these results to the ones obtained by using the Science Citation Index. The most cited journal was Medicina Clinica (768 cites), and the highest IF were attained by Histology and Histopathology (IF = 1.866), International Journal of Developmental Biology (IF = 1.654) and Medicina Clinica (IF = 1.125).This work has permitted to obtain the IF of 87 Spanish medical journals. Already detected in previous works, the leadership of the journal Medicina Clinica in Spanish medicine is confirmed. Spanish medical journals published in English have received a small number of cites from the ones published in Spanish. A low impact factor is not necessarily related to lack of quality, merit or relevance.

Objetivos: Se analiza la productividad y colaboracion de disciplinas y especialidades en el area del Abuso de Sustancias en las publicaciones cientificas firmadas por instituciones espanolas (2001-2005). Metodologia: A partir de las afiliaciones institucionales, en las que se hace constar habitualmente el departamento, servicio o unidad, se ha identificado y cuantificado la participacion de las diferentes areas del conocimiento en los trabajos recogidos en las bases de datos IME/Indice Medico Espanol, ISOC/Indice Espanol de Ciencias Sociales y Humanidades, SCI-Expanded/Science Citation Index-Expanded y SSCI/Social Sciences Citation Index. Resultados: En ISOC se han identificado 31 disciplinas y especialidades, con un 8,6% de documentos en colaboracion entre las mismas. En IME 55 especialidades medicas, con un 10,89% de documentos en colaboracion y en SCI-Expanded 62 especialidades y un 41,68% de documentos en colaboracion. Conclusiones: a) El Abuso de Sustancias, Psicologia, Psiquiatria, Epidemiologia-Medicina Preventiva y Salud Publica y Farmacologia son las disciplinas y especialidades que presentan el mayor indice de productividad, a las que se suman, en el caso de los trabajos publicados en revistas extranjeras Bioquimica-Biologia Molecular, Neurologia y Neurociencia; b) los trabajos publicados en las revistas espanolas recogidas en SCI-Expanded y en revistas extranjeras presentan indices de colaboracion entre disciplinas mucho mas elevados; c) las principales colaboraciones son las establecidas entre Abuso de Sustancias, Psiquiatria y Psicologia, a las que se suman, en el caso de las revistas recogidas en SCI-Expanded las colaboraciones que establecen estas disciplinas con la Farmacologia, Neurologia y Neurociencia.

Correspondencia a Juan Carlos Valderrama Zurián:Juan.Valderrama@uv.es Fundamento y objetivo: La preocupación por favorecer la igualdad de género constituye uno de los ámbitos prioritarios objeto de atención por parte de los gobiernos y los organismos gestores de las políticas científicas, destacándose la importancia de incluir la variable del sexo en los análisis evaluativos de la actividad científica y tecnológica. Se realiza un estudio comparativo desagregado por sexos de la producción científica de los investigadores españoles de elevada productividad en el área de las drogodependencias. Material y método: Se ha identificado el sexo de los 338 autores que han publicado más de cuatro artículos distintos durante el período 1999-2004 indexados en las bases de datos IME/Índice Médico Español y SCI/Science Citation Index, analizando comparativamente su productividad y patrones de colaboración considerando la variable sexo. Resultados: Entre los grandes productores (> 9 trabajos) del ámbito de las drogodependencias predominan los hombres (70%) frente a las mujeres (30%). Entre los productores moderados (5-9 trabajos), el 57% de los autores identificados fueron hombres frente a un 43% de mujeres. Se han observado diferencias estadísticamente significativas entre hombres y mujeres en los grandes productores en cuanto al número de trabajos publicados y personas con las que han colaborado. Conclusiones: En el área de las drogodependencias no existe una igualdad de género, especialmente cuando se considera la élite de la investigación. Resulta fundamental profundizar en estudios que evalúen de forma desagregada por sexos la productividad científica para acometer las medidas correctoras necesarias que permitan alcanzar la igualdad de género.
