Communities of Practice to Overcome Africa’s “Brain-Drain”: The Role of Information Communication Technology
No full textThe HIV/AIDS pandemic is decimating Africa’s productive age. Trained professionals in HIV/AIDS are in short supply in countrieswith developing economies. The current paper proposes the use of informationcommunication technology (ICT), videoconferencing in particular, for quicklytraining professionals. The author collaborated with several Diaspora groups tobring HIV medical management training to Ethiopia. The HIV medical management trainingcase study in Ethiopia is presented todemonstrate videoconferencing capabilities.
The current paper discusses a case where experts in the U.S. participated in trainingsenior physicians in Ethiopia. Connecting, via videoconferencing, Communities of Practicewith a common area of interest that reside in geographically dispersed regions is proposedas an alternative to overcome Africa’s brain drain
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
Perception of African Youth on Personal Computer Utilization: The Case of Ethiopia and Rwanda
No full textThe tendency to pursue innovativeness and adopt new technologies has been found more likely with younger individuals and a strong relationship between attitude and personal computer (PC) utilization has been found. However, research in these areas is mainly focused on high-income countries. Do these findings hold for low-income countries? What are the perceptions of African youth on the factors that impact PC use? There is a dearth of micro-level studies that promote understanding about the behavior of individuals in low-income countries. This study looked at demographic data including age, gender, grade level, region, and prior experience among 228 youth from Ethiopia and Rwanda. PC utilization constructs including complexity, long-term consequences, and facilitating conditions were studied. The author found access to PCs at least three times a week and providing structured computer training programs as major factor for increased PC utilization. Computer centers with more female instructors were found to have larger female enrollment. The author also found younger groups (15 year olds and younger) disagreed about PC utilization factors. Implications and directions for future research are also included
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
