Abstract: This study assesses possible advantages of open access can bring to the area of Information Science, using bibliometric citation indicators and Altmetric scores to analyze sixteen hybrid scientific journals, filtered by respective Impact Factors and included in the Journal Citation Reports. Data collection was performed using Web of Science, Google Scholar, Altmetric.com and Mendeley. The verification was performed in two periods in order to examine whether open access exerted influence over time. Results indicate that open access boost the number of citations and mentions in social media for the sample of papers drawn from journals under study. Moreover, this boost is greater when authors upon publishing pay the processing charge to guarantee the immediate open access availability of the paper. In conclusion, while open access can boost the number of citations of a paper, the quality of the paper itself drives most citations.

Resumen: El objetivo de esta investigación fue verificar las posibles ventajas que el acceso abierto puede ofrecer al área de la Ciencia de la Información. Para ello, se analizaron los indicadores bibliométricos de citas y los datos de altmetría en 16 revistas científicas híbridas, seleccionadas mediante el Journal Citation Reports y filtradas con base en sus respectivos factores de impacto. La recolección de datos fue realizada en Web of Science, Google Scholar, Altmetric.com y Mendeley. Esta verificación se realizó en dos periodos de tiempo diferentes para examinar si hubo alguna influencia del acceso abierto en el tiempo. Los resultados indican que el acceso abierto puede ofrecer una ventaja en el número de citas y menciones en las redes sociales para el conjunto de artículos de las revistas analizadas aquí, y que esta ventaja es mayor para los casos en que los autores pagaron el cargo por procesamiento del artículo a garantizar la disponibilidad inmediata del artículo en acceso abierto al momento de la publicación. En la conclusión se afirma que no es sólo el acceso abierto el que provoca una mayor cantidad de citas a un artículo, aunque ayuda, sino la calidad del propio artículo.

Coatings of amorphous metallic alloys can be obtained using different thermal spraying processes, such as HVOF, plasma spraying, cold spraying and others. Although many studies focused on investigating scientific issues concerning apply amorphous metallic coatings using thermal spraying, less attention have been paid to evaluate how research institutes and companies are collaborating and influencing each other to promote new technologies. In this paper, we assessed the collaboration of organizations and the knowledge flow on this relatively new field using bibliometrics and science mapping. The method relies on scientific publications indexed in Web of Science and clustered into research areas using the CWTS Publication-level Classification System. These results provide useful insights about how players are organized and may be used in the context of R&D management, science policy and decision making.

Thermal spraying processes allows high cooling rates and can favor the formation of amorphous microstructures. Amorphous metallic coatings can result in superior mechanical and functional properties. To follow new technological development and innovation paths, indicators based on patent data can be assembled to support technological forecasting assessments and decision making. This study mapped the technological development on amorphous alloys processed by thermal spraying using patent indicators from documents indexed in the Derwent Innovations Index database between the years 1997 and 2014. We evaluate the patent activity, the role of countries, the main technological subdomains and markets of interest, as well as the main metallic alloys explored as coating. We conclude that new technological developments should be expected in near future and these advances both in amorphous alloys and thermal spraying shall be constantly monitored in the coming years.

Com o intuito de contribuir para a temática dos estudos de uso e usuários, visando subsidiar a tomada de decisão mais racional e sustentável em relação à manutenção do acervo de uma biblioteca, este estudo teve como objetivo geral elaborar um conjunto de indicadores sobre o uso do acervo, por intermédio da técnica de análise bibliométrica e da análise das redes sociais. Como método de pesquisa, utilizou-se o estudo de caso, tendo como unidade-caso a Biblioteca Comunitária da Universidade Federal de São Carlos, campusSão Carlos, São Paulo. A amostra de dados analisada compreendeu 119.720 registros referentes à circulação (empréstimo, renovação e reservas) do acervo, no ano de 2011. Foram elaborados e analisados indicadores sobre a utilização do acervo pela comunidade, com auxílio do softwareVantagePoint(r). Com base nos resultados obtidos, pode-se afirmar que o uso da bibliometria e da análise de rede para a realização de estudos de usos, prevista na teoria de estudos de usos e usuários, mostrou--se eficaz para estabelecer indicadores referentes ao perfil de usuários e uso do acervo, de forma automatizada e sem contato direto com os usuários.

In order to contribute to the study of use and users of electronic library resources and to support higher rational and sustainable decisions regarding the maintenance of the library collection, the aim of this study was to develop a set of indicators on the use of the library collection by means of bibliometric and social network analyses. The research method was a case study and the single unit assessed was the Community Library of the Universidade Federal de São Carlos, located in São Carlos, São Paulo. The data sample consisted of 119,720 records of book circulation (loan, renewal and booking) from 2011. The indicators of the community use of the library collection were developed and the VantagePoint(r) software was used to evaluate them. Based on the results obtained, it can be stated that the use of bibliometrics and network analysis for conducting studies of uses, as predicted in the studies of uses and users, were effective to automatically establish indicators for the user profile and use of the collection without direct contact with users.

Nanocellulose is remarkable cellulose-based nanomaterials that have a potential for innovation and sustainable appeal. Their advances can be assessed using patent indicators and text mining techniques. The aim of this study was at analyzing the advances in nanocellulose based on indicators compiled from patents filed at the United States Patent and Trademark Office (USPTO) from 2000 to 2012. Assignees, technological subjects, highly cited patents, applications and types of nanocellulose were obtained by mining structured and unstructured data. The results highlighted the different interests in the USA market, mainly after 2007. Mined terms from titles and abstracts could add further information to the analysis. However, although the method applied was useful, it was not sufficient to identify all applications and types of nanocellulose involved in the sample analyzed, therefore it is recommended that other document parts be included in future analyses.

This research aims to examine scientific and technological trends of developments in nanocellulose based on scientometric and patent indicators obtained from the Science Citation Index and Derwent Innovations Index in 2001-2010. The overall nanocellulose activity indicators were compared to nanotechnology and other selected nanomaterials. Scientific and technological future developments in nanocellulose were forecasted using extrapolation growth curves and the main countries were also mapped. The results showed that nanocellulose publications and patent documents have increased rapidly over the last five years with an average growth rate higher than that of nanotechnology and fullerene. The USA, Japan, France, Sweden and Finland all played a significant role in nanocellulose development and the extrapolation growth curves suggested that nanocellulose scientific and technological activities are still emerging. Finally, the evidence from this study recommends monitoring nanocellulose S&T advances in the coming years.
