Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Improving competences of engineering graduates through student industrial secondments : a study in East Africa
Get PDFRelative shortage of engineering practitioners in sub-Saharan Africa has been reported as a major concern in many studies on industrial and technological development of the region. However, the region simultaneously records a significant number of existing engineering graduates who find it difficult to find employment in engineering fields. While that situation reflects the inability to absorb human capital in industrial processes, it can also be partly explained by a relative deficit (real or perceived) in the competency of local engineering graduates in the ever-advancing areas of science, technology, engineering, and mathematics (STEM), and/or a scarcity in opportunities to hone and demonstrate competency of local engineering graduates in the labour market. Consequently, local engineering graduates have inadequate hands-on experience needed in industries as well as for establishing start-up engineering firms/businesses. To address this situation, it was postulated that promoting engineering student industrial secondment (SIS) programmes can be a suitable approach to strengthening the linkages between engineering education, practice and employability
Challenges around employability of engineering graduates in Africa : can industrial secondments be a remedy?
Get PDFWith the shortage of local, competent engineering practitioners being a challenge to sustainable development, existing engineering ecosystems need to transform and address the challenge. The SIS project has shown potential in improving the professional competence (and thus employability) of engineering students through methods such as student industrial secondment (SIS) programmes and problem-based learning, among others. However, for such methods to work properly, more efforts and effective coordination among stakeholders in the engineering ecosystem are required
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
Leverage points in engineering ecosystems: student industrial secondments in East Africa
Get PDFWhile the relative shortage of engineering practitioners in Africa has been reported as a major obstacle on the road to development, a significant number of existing engineering graduates still find it difficult to find employment in engineering fields. This dichotomy may be partially explained by the inability of local industries to absorb more skilled labour; a relative deficit (real or perceived) in the competency of local graduates in the ever-advancing areas of science, technology, engineering and mathematics (STEM); and/or a scarcity of opportunities to hone and demonstrate their competency to employers. To address the challenge of competency deficit, this study postulated that promoting effective engineering student industrial secondment (SIS) activities can be a leverage point in the engineering ecosystem by strengthening the linkages between engineering education, practice and employability. The study surveyed the history of engineering practical training in Tanzania, Kenya, Uganda and Rwanda, complemented with a pilot study of four long-term, employment-like SIS placements in Tanzania and Rwanda. The main objective was to observe closely, trial potential models, and learn from and synthesise effective SIS experiences. The study found similarities across the countries regarding experiences with student practical training models, their challenges, and the perspectives of stakeholders. Findings also support that longer durations of SIS placements than currently practised help increase the employability of engineering students. However, in view of the small number of placements, further evidence is called for
