A validação da ciência: dos processos tradicionais aos novos modelos
No full textA revisão editorial por pares ou peer review é um mecanismo
essencial na validação da ciência, garantindo o cumprimento dos
critérios de qualidade no que diz respeito ao conteúdo e à forma
do que é submetido para publicação. Apesar da sua importância
tem sido alvo de críticas e de falhas na adaptação à publicação
em meio digital. Dando corpo a um dos pilares da Ciência Aberta
a revisão por pares aberta e as novas modalidades de revisão
apresentam-se como uma alternativa que se pretende mais transparente, mais colaborativa e mais adequada à velocidade das
descobertas científicas.Peer review is an essential step in the validation of science,
it guarantees the quality of research and that content-related and
form-related criteria are met in all that is submitted for publication.
Despite its importance it is often contested and accused of failure in
adapting to digital publication. As one of the pillars of Open Science,
open peer review and the new review possibilities are presented as
an alternative that aims to be more transparent, more collaborative,
and better suited to the speed of scientific discoveries821F-CED0-75EA | Maria Manuel Lopes de Figueiredo Costa Marques Borgesinfo:eu-repo/semantics/publishedVersio
Dos sistemas isolados aos partilhados: o repositório institucional da Universidade de Coimbra
Full text linkFor researchers it is crucial to have access to scientific information. However, there are barriers to access this information that must be overcome. This is not a problem that affects only developing countries. The United Kingdom, United States, Canada and Australia are, among others, the most active in setting up institutional or thematic repositories as a complementary way to have access and disseminate the scientific information, which is essential to potentiate its impact. This study pretends to show the approach and methodology used on the case study for the implementation of an institutional repository at the University of Coimbra
Um estudo preliminar sobre a aplicabilidade da arquitetura orientada a serviços na concretização do modelo OASIS
No full textO A oferta crescente de informação digital, a qual, no âmbito da Ciência Aberta, exige maior robustez política e tecnológica dos sistemas que a suportam, os repositórios digitais, justificam uma atenção redobrada tanto às políticas de preservação quando aos modelos conceptuais que especificam os requisitos a que devem atender. O modelo OAIS (Open Archival Information System) desempenha um papel fundamental no domínio da preservação digital com o objetivo de padronizar as suas atividades e especificar os principais critérios nos quais as iniciativas de preservação digital devem ser baseadas. O presente trabalho visa, através de uma revisão da literatura, contribuir para a discussão do modelo de referência OAIS, suas entidades, seus processos e características no domínio da preservação digital, analisando os potenciais desafios relacionados com a falta de consistência e interoperabilidade,
possivelmente presentes nas diferentes implementações de softwares baseadas nesse modelo. Como resultado, este trabalho sugere um estudo preliminar sobre a aplicabilidade de uma arquitetura aberta de software baseada numa Arquitetura Orientada a Serviços (SOA) para os processos Archival Storage e Access no modelo OAIS, visando promover uma maior flexibilidade na comunicação entre as diferentes implementações de softwares baseadas nesse modelo, bem como uma forma interoperável, transparente e aberta no acesso ao conteúdo digital numa nova era da sociedade contemporânea e para uso na Ciência Aberta.821F-CED0-75EA | Maria Manuel Lopes de Figueiredo Costa Marques Borgesinfo:eu-repo/semantics/publishedVersio
O impacto das bibliotecas digitais de patentes no processo de inovação em Portugal
Full text linkInformation is an essential resource to the functioning and survival of organizations. In order for organizations to compete in a global environment, with rapid changes, where they move nowadays, they need to obtain information that’ll allow them to innovate and acquire competitive advantages in the markets they operate in. Scientific and technical information associated to Industrial Property – Patent Information - can provide further competitiveness through the transfer of technology that it motivates and is of vital economic importance due to the innovation that it stimulates.
After analysing several Indicators, National and International Studies, we realized that Portugal is not using the resources of the Industrial Property’s records in a satisfactory way, not taking advantage of its benefits. The data published shows that university research centres are not living up to their full potential when it comes to using this type of information since it could, when due integrated into research projects, motivate innovation, provide competitive advantages, and increase the number of IP records. This could lead to an increase of the number of new companies and to economic growth. We support that a coherent and effective use of Patent Digital Libraries that contain information resulting from R&D activities with industrial applications can contribute to the increase of creativity and support problem- solving in research, developing innovation through the resulting new products and processes. This research attempts to answer the question about the relationship between the degree of knowledge and level of usage of Patent Digital Libraries by research centres in Portugal and their contribution to the innovation process. The hypothesis to validate is that University Research Centres that know and use the information in the PDL are more innovative since they contribute with more patents and they generate more new products and processes, giving birth to more spin-offs with industrial applications
Caracterización y presencia en las redes sociales de las publicaciones científicas sobre Open Science de España y Portugal
No full textEn este trabajo se presenta un análisis de la producción científica sobre Ciencia Abierta de España y Portugal recogida en la base de datos SCOPUS. Se utilizan técnicas bibliométricas para obtener indicadores que permitan caracterizar las publicaciones obtenidas. Se incluyen también indicadores altmétricos para dar cuenta de la repercusión de la producción en redes sociales. Los resultados obtenidos muestran que, entre 2000 y 2016, se han producido 569 documentos sobre esta temática en la Península Ibérica. Ambos países se muestran muy activos en este tema con especial productividad en los últimos 5 años y en cuestiones vinculadas con Open Science y Open Data. Las publicaciones corresponden especialmente a revistas de Computer Science y Social Science y predominan los textos en inglés. Los indicadores altmétricos obtenidos muestran que, en torno a un 33% de los documentos con DOI, tienen repercusión en las redes sociales predominando las menciones en tweets y los lectores en Mendeley. Se ha detectado una relación positiva entre este último indicador y las citas de las publicaciones.821F-CED0-75EA | Maria Manuel Lopes de Figueiredo Costa Marques Borgesinfo:eu-repo/semantics/publishedVersio
Modelo de fatores que influenciam no comportamento de compartilhamento de dados de pesquisa (MFDados)
No full textO processo de compartilhamento de dados em plataformas digitais engloba várias questões tanto sociais quanto tecnológicas.
Essas questões são complexas e precisam ser avaliadas para se
estabelecer um diagnóstico sobre a percepção de um conjunto de
pesquisadores pertinente ao compartilhamento de dados de pesquisa em plataformas digitais, como repositórios. É fundamental,
nesse sentido, a identificação dos fatores que influenciam o comportamento de compartilhamento ou retenção nesses ambientes.
As Redes de Interação Técnico-Social e a Teoria da Troca Social fundamentam a construção do Modelo de Fatores que Influenciam o
Comportamento de Compartilhamento de Dados de Pesquisa. Esse
modelo apresenta os fatores de custos, de benefícios e os fatores
contextuais que podem influenciar o pesquisador na questão do
compartilhamento de dados de pesquisa. Ao identificar as barreiras percebidas pelo pesquisador é possível tentar minimizá-las.
E, identificando os benefícios compreendidos por ele, é possível
elaborar serviços e produtos que estimulem o pesquisador ao compartilhamento. Por fim, discriminando os fatores contextuais é
possível verificar quais elementos desses contextos são favoráveis
e quais são desfavoráveis ao compartilhamento na percepção do
pesquisador. Este modelo foi aplicado na área de neurociências
em instituições de pesquisa, no Brasil e em Portugal, e está sendo
aplicado em outras instituições do campo da saúde para compreender a percepção dos pesquisadores da instituição e promover o
compartilhamento de dados de pesquisa. Neste capítulo não serão
apresentados os resultados da aplicação do modelo, limitando-se
a apresentação do Modelo em detalhes.The process of sharing data on digital platforms encompasses
many social as well as technological issues. These complex issues
need to be evaluated in order to establish a perception of a set of
researchers regarding the sharing of research data in technological
environments. Identifying the factors that influence sharing or retention behavior in these environments is critical. The Social-Technical
Interaction Networks and the Social Exchange Theory underlie the
construction of the Model of Factors that Influence the Research Data Sharing Behavior. This model presents the cost, benefit, and
contextual factors that may influence the researcher on the issue of
research data sharing. By identifying the barriers perceived by the
researcher it is possible to try to minimize them. By identifying the
benefits it understands, it is possible to design services and products
that encourage researchers to share. Finally, by identifying contextual
factors, it is possible to verify which elements of these contexts are
favorable and which are unfavorable to sharing in the researcher’s
perception. This model has been applied in the area of neuroscience
in research institutions in Brazil and Portugal and is being applied
in other health institutions to understand the perception of researchers of the institution and to promote the sharing of research data821F-CED0-75EA | Maria Manuel Lopes de Figueiredo Costa Marques Borgesinfo:eu-repo/semantics/publishedVersio
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
