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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
O Repositório Científico do Instituto Politécnico de Castelo Branco
Full text linkO Repositório Científico do Instituto Politécnico de
Castelo Branco, adiante designado por RCIPCB ou simplesmente
por Repositório, resulta de uma candidatura
apresentada, pelo Instituto Politécnico de Castelo Branco
(IPCB) à Fundação para a Computação Científica Nacional
(FCCN) em Setembro de 2009 e que mereceu parecer
favorável, já que o IPCB reunia os requisitos necessários à
sua constituição, em termos de produção científica.
Não possuindo desde logo um repositório próprio, o
RCIPCB integrou o Serviço de Alojamento de Repositórios
Institucionais (SARI) que é um sistema utilizado pelas instituições
do sistema científico e de ensino superior que permite
às instituições que não possuem o seu próprio repositório,
dispor de uma plataforma devidamente estruturada e que
lhes incumbe alimentar através do depósito de documentos.
A implementação do RCIPCB veio proporcionar maior
visibilidade à produção científica do IPCB, facilitando o
acesso ao respectivo conteúdo, uma vez que este se encontra
em suporte digital. Está igualmente disponível através
da b-on e pesquisável através da Web (Google, Google
Scholar, etc.) de forma rápida e eficiente.
O Repositório Científico do IPCB permite também o
acesso directo à Plataforma DeGóis - plataforma de gestão
de curricula científicos, possibilitando aos autores importar
directamente a sua informação, sem necessidade de duplicar
o esforço de preenchimento dos dados.
Em Novembro de 2009, o RCIPCB integrou o Portal
Repositório Científico de Acesso Aberto de Portugal
(RCAAP), completando-se assim o ciclo da sua criação
"Cuidar" do repositório : um fator crítico de sucesso
No full textDe um modo geral podemos definir os repositórios científicos, institucionais ou outros, como estruturas informacionais que agregam dados, metadados e documentos em um único local, permitindo que qualquer cidadão, com acesso à Internet, em qualquer parte do mundo tenha acesso aos seus conteúdos de forma livre e gratuita. Fundamentam o seu funcionamento no princípio do livre aceso ao conhecimento. Como qualquer
estrutura necessitam de ser cuidados e mantidos de forma a cumprirem eficazmente a sua missão no respeito pelos respetivos conteúdos, formas de acesso e, não menos importante, pelos autores, suas limitações e
indicações. Este trabalho pretende mostrar de que forma o Repositório Científico do Instituto Politécnico de Castelo Branco (RCIPCB) “cuida” dos seus conteúdos, dados, metadados e documentos tendo em vista a manutenção da sua integridade, fiabilidade e imagem para o exterior e quais os processos e metodologias utilizados na instituição na prossecução deste objetivo.Institutional scientific repositories are structures that aggregate data, metadata and documents in a single
location. They are very inclusive and allow any citizen with Internet, anywhere in the world, to access to their contents freely and free of charge. Generally, they provide access to the full text of the documents and
follow the open access (OA) to information principles. In this way they allow users to read, to use, to download and reuse, the full text of their documents. Like any other informational resource, they need to be cared and maintained in order to effectively fulfill their mission. So, there are some curation activities needed to be done in order to guarantee big quality, reliability and confidence in the contents they provide. Present work
aims to demonstrate the methodologies and the strategy used by the Scientific Repository
of the Polytechnic Institute of Castelo Branco (RCIPCB) to “taking care” of its contents, data,
metadata and documents. These were considered good practices to follow in the curation
activities in order to improve and/or maintain the quality of their records with impacts also in
the digital preservation of the information and documents they provide.info:eu-repo/semantics/publishedVersio
