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
Internet and Mathematic Education (E-Learning objects and tools for Mathematics Education)
No full textThis paper analyzes some e-learning objects and didactics tools for improving mathematics education. The learning objects and tools analyzed are Videos, Applet Java, Geogebra, Wolfram|Alpha with his Widgets, Google Spreadsheets and Wiris. The analysis has been based on the parameters considered more suitable for didactics of mathematics. Such parameters are: interactivity, shareability, availability, applicability and feasibility.
The paper presents a brief description of how the didactics is changing with internet, in particularly the didactics of the mathematics. It then shows the objects and tools selected with some application examples. Finally, it illustrates an comparison of the objects and tools based on the parameters listed above
Smartening sustainable development in cities: strengthening the theoretical linkage between smart cities and SDGs
No full textIn 2015, the United Nations General Assembly set up 17 interlinked global goals designed to be a blueprint to achieve a better and more sustainable future for all, which are commonly addressed as SDGs. In this blueprint, cities are seen as a hotspot for achieving those goals by 2030. In this context, cities, through smart technologies, are engaging in generating a sustainable ecosystem that is inclusive of social and environmental concerns. The main objective of this paper is to assess the effect of SDGs institutionalization on the concept of smart sustainable cities. To this end, we review the literature on smart cities and SDGs to analyze the degree of alignment and potential areas of development. The results reveal the existence of brokerage keywords, which rank high in both fields of the literature, but are missing from the portfolio of overlapping keywords. This is the case for water management, energy, governance, and collaboration. While concepts such as sustainability, waste management, civic engagement, and innovation are in common, albeit explored differently
