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

Transformação digital, um desafio na educação superior
Full text linkThe parsimonious progress towards the digital transformation of education has been one of the edges of the educational crisis experienced in Latin America, whose reality became more evident with the abrupt pandemic situation where the conditions of inequality and poverty take on a greater impact harmful to the less favored social classes, the human right to education being flagrantly violated. In the case of higher education, this problem is exacerbated by the bias of particular interests, a traditionalist governance, rigid curricula, teachers with little or no training in pedagogies with the use of technology, and students with minimal or no opportunities to access a computer. Internet. As a conclusion we can indicate that the contribution made by professionals in computer science and engineering is abysmal, but no effort will be enough if students are not allowed access to information and communication technologies in an equitable way, declaring this as a violation of first generation constitutional rights such as equality and others such as access to quality education. Against this background, will the digital transformation be able to support universities in the resilient action they must adopt to safeguard engineering education or will it increase the gap during pandemic and post-pandemic?El progreso hacia la transformación digital de la educación, ha sido una de las aristas de la crisis educativa vivida en América Latina, cuya realidad se hizo más evidente con la abrupta situación de pandemia dondelas condiciones de desigualdad y pobreza, cobran un mayor impacto nocivo en las clases sociales menos favorecidas, siendo flagrantemente vulnerado el derecho humano a la educación. En el caso de la educaciónsuperior esta problemática se agudiza con el sesgo de intereses particulares, una gobernanza tradicionalista, currículos rígidos, docentes sin o poca formación sobre pedagogías con uso de la tecnología y estudiantescon mínimas o nulas oportunidades de acceso a un computador y a internet. Como conclusión podemos indicar que el aporte que hace los profesionales de las ciencias computacionales y la ingeniería es abismal,pero ningún esfuerzo será suficiente sino se permite el acceso a los estudiantes de forma equitativa a las tecnologías de la información y las comunicaciones, declarando esto como una violación a los derechosconstitucionales de primera generación como la igualdad y otros como el acceso a una educación de calidad. Ante este panorama, ¿la transformación digital respaldará la educación en ingeniería frente a pandemiay post-pandemia?O avanço na transformação digital da educação tem sido uma das pontas da crise educacional vivida na América Latina, cuja realidade se tornou mais evidente com a abrupta situação de pandemia em queas condições de desigualdade e pobreza têm maior impacto prejudicial. classes sociais, o direito humano à educação sendo flagrantemente violado. No caso do ensino superior, esse problema é agravado pelo viésde interesses particulares, uma governança tradicionalista, currículos rígidos, professores com pouca ou nenhuma formação em pedagogias com uso de tecnologia e alunos com oportunidades mínimas ou nenhumade acesso já a um computador Internet. Em conclusão, podemos indicar que a contribuição dos profissionais da informática e da engenharia é abismal, mas nenhum esforço será suficiente se os alunos não tiveremigual acesso às tecnologias de informação e comunicação, declarando isso uma violação dos direitos constitucionais de primeira geração. como a igualdade e outros como o acesso à educação de qualidade. Nessecontexto, a transformação digital apoiará a educação em engenharia em face da pandemia e pós-pandemia

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
