Mapping the Situation of Educational Technologies in the Spanish University System Using Social Network Analysis and Visualization

Educational Technologies (EdTech) are based on the use of Information and Communication Technologies (ICT) to improve the quality of teaching and learning. EdTech is experiencing great development at different educational levels worldwide, especially since the appearance of Covid-19. The recent publication of a study by the ICT Sectorial of CRUE Universidades Españolas, the Spanish University Association, is the first report on the implementation of such technologies within Spain´s University System. This paper presents two different maps based on the data from that report. Together, they illustrate the penetration of different types of EdTech in our university system and shed light on the strategic interest behind their adoption. Our goal is to produce self-explanatory maps that can be easily and directly interpreted. The first map reflects wide granularity in terms of the global importance of technologies, while the second points to relevant conclusions given the spatial position of Spain´s universities, and the size of the nodes that represent them (directly related with their strategic interests on EdTech), as well as with the local relationships existing among them (identifying similarities on those strategic interests).Working Group in Online Training and Educational Technologies (FOLTE), of the ICT Sectorial of the Commission of Rectors of Spanish Universities (the Spanish University AssociationCRUE Universidades Españolas).

How to Combine Research Guarantor and Collaboration Patterns to Measure Scientific Performance of Countries in Scientific Fields: Nanoscience and Nanotechnology as a Case Study

This paper presents a comparative benchmarking of scientometric indicators to characterize the patterns of publication and research performance at the country level, in a specific field (nanoscience and nanotechnology) during the period 2003–2013. The aim was to assess how decisive collaboration may be in attaining a sound level of scientific performance, and how important leadership is for publication. To this end, we used a new methodological approach that contributes to the debate about scientific autonomy or dependency of countries in their scientific performance, and which may serve as an aid in decision-making with regard to research management. The results reveal that in terms of output, USA and China are the main producers; and due to the huge increase in their publications, Iran, India, and Australia can be considered emerging countries. The results highlight USA, Ireland, and Singapore as the countries with the highest levels of normalized citation impact, scientific excellence, and good management of leadership, all of which suggest strong scientific development and scientific autonomy. Also worth mentioning is the high visibility and scientific consolidation of China and Australia, despite the meager growth of their output. Moreover, the performance results indicate that in most cases the countries whose pattern of publication is more international tend to have greater visibility. Yet, a high degree of leadership does not always translate as a high performance level; the contrary is often true. Due to the limitations of the sample and characteristics of the field, we propose that future studies evaluate the generation of new knowledge in this field and refine the approach presented here, so as to better measure scientific performance.Projects I + D + I, State Programme of Research, Development and Innovation oriented to the Challenges of the Society: NANOMETRICS (Ref.

Especialización temática de la producción científica

La evaluación de la investigación científica de países y regiones del mundo por medio de indicadores bibliométricos es una actividad con una larga tradición. Price, Braun, Glanzel y Schubert, entre muchos otros, han realizado aportaciones de gran relevancia a esta materia. Mediante el uso de indicadores es posible detectar, observar y analizar aspectos tales como los grandes cambios en las regiones productoras de conocimiento, así como en los países que las integran. Se ha detectado, por ejemplo, un ritmo de producción exponencial en algunos países asiáticos, la emergencia de países la- tinoamericanos como Brasil, la expansión del bloque de la Europa occidental, así como el estancamiento relativo de la producción norteamericana, que parece estar llegando a su límite de saturación. Estos indicadores nos permiten saber que son tres las regiones que acumulan más del 80% de la producción: Norteamérica, Europa occidental y Asia, y que en 2007, Europa occidental supera a Norteamérica en producción bruta, mientras que la región asiática prácticamente la iguala. El objeto de este capítulo es caracterizar el perfil temático español por áreas de conocimiento. Para ello, en una primera parte del capítulo se revisa la situación en cada una de las áreas temáticas por separado, mientras que en la segunda se hace a partir de un análisis multivariante de todas ellas con el fin de situar a España en el contexto mundial. La fuente de información utilizada ha sido el portal SCImago Journal & Country Rank,desarrollado por el Grupo SCImago a partir de la base de datos Scopus, la mayor base de datos de literatura científica mundial, que recoge cerca de 18.000 de las principales revistas del mundo y alrededor de 38 millones de documentos. Su cobertura es mejor que la de otras bases de datos utilizadas con los mismos fines. Finalmente, el periodo de tiempo de análisis comprende los años 2003 a 2007, ambos inclusive. Dada la naturaleza y alcance de este capítulo, se pondrá el énfasis en dos indicadores bibliométricos básicos: producción y citación. Asimismo, se ha reducido al mínimo toda mención metodológica. Para un tratamiento metodológico detallado y que considere un abanico más amplio de indicadores, recomendamos los informes sobre la ciencia española realizados por el Grupo SCImago para la FECYT

Perspectives around the cognitive model for the information retrieval: a critical analysis / Enfoques en torno al modelo cognitivo para la recuperación de información: análisis crítico

The traditional or algorithmic model of information retrievalhas evolved into the cognitive model. From the latter, differentproposals for practical implementation have arisen being the most remarkable ones those labelled by their own authors asGlobal Model of Polirepresentation, Episodic Model, StratifiedModel and Model of Interactive Feedback. These are criticallydescribed and analysed in this paper

Investigación española en células madre (1997-2010). Localización y evolución de las principales líneas de investigación a través de los KeyWords Plus

•Objective: To render and analyze the evolution and dynamics of the main research lines in the Spanish scientific output on stem cells between 1997 and 2010. •Material and Methods: We retrieved the documents from the Science Citation Index (SCI). The units of analysis were the descriptors KeyWords Plus (KW +). The tools used for visualization have been software Pajek combined with Pathfinder Network (PFnet), and VOSviewer software. This study analyzes the period includes between 1997-2007, and the evolution of the research into three sub-periods: 1997-2001, 2002-2006 and 2007-2010. •Results and Discussion: The results of the full period locate up to six main research lines. In the first period, there is a strong presence of the descriptors that represent documents related to hematology and oncology. However, the other research lines do not begin to be clearly detected until the second period. Here,we can locate clusters of descriptors related to hematopoietic stem cell research, others related with the generation, proliferation and differentiation of stem cells and finally, alternate associated to an emerging cluster of neural progenitor cells. The results show that the weight of these latter groups make them more evident in the last period. •Conclusion: The visualization of the relationships between the KW + has yielded two complementary images of the situation and evolution of Spanish research on stem cells. The methodology has identified areas of research both consolidated and emerging, intuiting the development of a thematic domain over time. The visualization software complement each other quite well, matching in the identification of the main research lines and in the location of the most influential descriptors

SPECIAL TRACK: Present and future of research metadata: where do we want to go from here?

To steer the scientific system towards specific goals, it is first necessary to develop an effective understanding of all phases and aspects of the research workflow. Research metadata, as the collective record of traces that are generated when scientific activities take place, serves as evidence of these activities. Therefore, the availability of authoritative research metadata is essential for science-related decision-making at various levels. In the past, large-scale research metadata collections mostly dealt with items in the public record, such as bibliographic metadata about academic publications. There used to be few of these large-scale metadata collections, and they were often provided by commercial actors, those which invested the necessary resources to compile and process disperse public information with the goal of turning it into usable services. As the capabilities of available technologies increase, each day more sectors of the scientific system are becoming aware of how their activities could benefit from updating their workflows, a process often referred to as digital transformation. Thus, a plethora of tools and standards are being developed to streamline processes, increase interoperability, and in general overcome the limitations of the paper era. This is having a large effect in the quantity and quality of research metadata that is now being recorded. A clear example of the above is the case of bibliographic metadata. Currently, an increasing number of organizations, spurred by the decreasing barriers to collecting and processing large amounts of bibliographic metadata, are already providing services and datasets that rival the offerings of the traditional commercial providers. Some of these new datasets, provided under open licenses that allow unrestricted reuse and redistribution, have boosted innovation by allowing the development of downstream applications that rely on these metadata collections. However, as scientific activities in general and scientific communication in particular are increasingly moving to the digital space, traditional bibliographic metadata is no longer the only kind of research metadata that is being collected and processed at a large scale to inform decisions. Social network platforms now capture a portion of academic-related conversations and other kinds of interactions. Processes such as peer review that were previously carried out behind closed doors are now being opened, generating their own public trace. Publishing platforms are implementing increasingly sophisticated methods to track and mine user actions for their benefit. All these recent developments call for a discussion on the role of research metadata in the scientific system going forward. This discussion should be open to a large variety of stakeholders, including data providers, scientometricians, academic librarians, higher education institutions, policy managers, and developers of downstream applications. The topics of the contributions to this special track can include: • Analyses of the suitability of research metadata sources for specific use cases • Sustainability and governance of research metadata • Innovations in research metadata • Downstream applications of open research metadata • Surveillance through research metadata Contributions to this special track would be open to everyone interested and peer-reviewed. The format of the session would be 15-20 minutes per presentation, with time for questions after each presentation

Patrones de comunicación e impacto de la producción científica cubana en salud pública

[EN] Objective: to characterize the Cuban pattern of scientific communication in public health in Scopus database on the basis of the output and collaboration patterns and their influence on the impact of publications.Methods: bibliometric indicators of output, visibility and collaboration taken from SCImago Institutions Rankings and SCImago Journal and Country Rank portals were used, according to Scopus database, in the Public Health, Environmental and Occupational Health category in 2003-2011 period.Results: the communication pattern showed an increasing tendency of the scientific output, with great leadership of Cuban authors and poor national and international collaboration. This increase did not have a higher impact on the international community; 7.22 % of documents were published in high impact journals and 2.16 % were among excellence documents. The excellence output with leadership was almost non-existent. Seventy five percent of the output was seen in low impact journals (fourth quartile) and most of it in national journals. The English output accounted for less than 30% of the total amount but had higher impact than the Spanish articles.Conclusions: the pattern of Cuban scientific communication in public health was characterized, in which low number of English publications, of publications in high impact journals and poor national and international collaborations are factors that may influence on the low scientific impact. These results can be used to supplement the assessment of research in public health within the tenth basic function of this specialty.[ES] Objetivo: caracterizar el patrón cubano de comunicación científica en salud pública en la base de datos Scopus a partir de los patrones de producción y colaboración y su influencia en el impacto de las publicaciones.Métodos: se aplicaron indicadores bibliométricos de producción, visibilidad y colaboración extraídos de los portales SCImago Institutions Rankings y SCImago Journal and Country Rank a partir de datos de Scopus, categoría Public Health, Environmental and Occupational Health, período 2003-2011.Resultados: el patrón de comunicación presentó una tendencia al incremento de la producción científica con un alto liderazgo de autores cubanos y escasa colaboración nacional e internacional. Este incremento no repercutió en un mayor impacto en la comunidad internacional; el 7,22 % de los documentos aparecieron en revistas de alto impacto, y el 2,16 % entre los documentos de excelencia. La producción de excelencia con liderazgo fue casi inexistente. El 75 % de la producción se ubicó en revistas de bajo impacto (cuarto cuartil) y la mayoría en revistas nacionales. La producción en inglés representó menos del 30 % del total y alcanzaron mayor impacto que los artículos en español.Conclusiones: se caracterizó el patrón de comunicación científica cubano en salud pública, donde la poca publicación en inglés, en revistas de alto impacto y la insuficiente colaboración nacional e internacional son factores que pudieran estar influenciando en el bajo impacto científico. Estos resultados pueden utilizarse como complemento de la evaluación de la investigación en salud pública en el marco de su décima función esencial.

Bibliometric analysis of regional Latin America's scientific output in Public Health through SCImago Journal & Country Rank

Background: In the greater framework of the essential functions of Public Health, our focus is on a systematic, objective, external evaluation of Latin American scientific output, to compare its publications in the area of Public Health with those of other major geographic zones. We aim to describe the regional distribution of output in Public Health, and the level of visibility and specialization, for Latin America; it can then be characterized and compared in the international context. Methods: The primary source of information was the Scopus database, using the category “Public Health, Environmental and Occupational Health”, in the period 1996–2011. Data were obtained through the portal of SCImago Journal and Country Rank. Using a set of qualitative (citation-based), quantitative (document recount) and collaborative (authors from more than one country) indicators, we derived complementary data. The methodology serves as an analytical tool for researchers and scientific policy-makers. Results: The contribution of Latin America to the arsenal of world science lies more or less midway on the international scale in terms of its output and visibility. Revealed as its greatest strengths are the high level of specialization in Public Health and the sustained growth of output. The main limitations identified were a relative decrease in collaboration and low visibility. Conclusions: Collaboration is a key factor behind the development of scientific activity in Latin America. Although this finding can be useful for formulating research policy in Latin American countries, it also underlines the need for further research into patterns of scientific communication in this region, to arrive at more specific recommendations.We acknowledge support of the publication fee by the CSIC Open Access Publication Support Initiative through its Unit of Information Resources for Research (URICI)
