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
Technology Driven Curriculum for 21st Century Higher Education Students in Africa
No full textThe book consists of novel and empirical research in broad areas of technology and curriculum in selected African countries. The central theme of the book is technology and the higher education curriculum. The book consists of case studies from selected African countries, namely, Lesotho; Namibia; Kenya; South Africa; Zimbabwe; Tanzania and Nigeria. These studies confirm that in this contemporary digital era, educational technology is playing an increasingly important role. It has become so ubiquitous and fundamental in the teaching and learning. Higher education sectors across the continent are increasingly compelled to use educational technology to keep up with needs of 21st century students who want to be afforded opportunities to be able to learn in real time, anytime, and on their own terms using opportunities for creative innovation made possible by new information and communication technologies
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
ADOLESCENT GIRLS’ PERCEPTIONS ABOUT HIV AND AIDS-RELATED RISKY BEHAVIOURS: ARE WE CLOSER TO COMBATING THE PANDEMIC AMONG SOUTH AFRICA’S YOUTH?
Get PDFPublished ArticleSouth Africa has reportedly the largest number of people living with HIV and AIDS in the world. Although adolescents as a group comprises the greatest portion of infected people, their behaviours and perceptions about the disease leave a lot to be desired. The purpose of this article is to explore some South African adolescent girls’ risky behaviours and perceptions about HIV and AIDS. A qualitative case study approach, using a school in Soweto, Johannesburg, was adopted. The paradigmatic position was interpretive. Twelve adolescent girls aged between 15 and 19 were purposively selected to participate in semi-structured interviews. Data were qualitatively processed to discern themes. Results showed that adolescent girls have comprehensive knowledge about HIV and AIDS, but they indulge in risky sexual behaviours because of ignorance, peer influence and a need to access government child support grants. The study concludes that unless there is a sharp turn-around in the youthful adolescent girls’ perspectives on HIV and AIDS, the country’s efforts to attain a Sustainable Development Goal of combatting HIV and AIDS, will remain elusive
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
Managing the Link between Academic Development and the Scholarship of Teaching and Learning: The Case of South African Universities
Get PDFPublished ArticleThe link between Academic Development (AD) and the Scholarship of Teaching and Learning (SoTL) in the
South African Higher education quality context is as blurred as the conceptualisation of the terms. Academic development is
a relatively ‘young’ discipline. It has come into being due to a wide variety of education pressures and needs locally and
worldwide. Currently in South Africa, there appears to be no unified understanding of the purpose, role and practices among
Academic Development practitioners. As such, managing AD practices is still quite ‘ad hoc’ and needs driven to the extent that
even in one institution there are possible differences in how the practitioners conceptualise their roles and practices as data
herein will show. Using three South Africa Universities and the ‘Best Practices’ frame of reference, this paper attempts to reveal
the assumptions and perceptions that underline AD practitioners’ understanding of their (AD management) roles which ultimately
shape their (scholarship of) teaching and learning practices. The intention is to establish if respective AD models and practices
influence significantly on teaching and learning within respective institutions. Five purposively selected AD practitioners
responded to a questaview that sought to unravel these assumptions and perceptions. Data were qualitavely analysed to discern
trends if any. Recommendations and implications on higher education quality and access and teaching and learning policy are
discussed within the context of the results
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
