An exploration of mediation in an intervention programme for educationally disadvantaged medical students
No full textIncludes bibliographical references (leaves 163-177).This thesis explores the academic and cognitive difficulties that educationally disadvantaged first year medical students experienced prior to the Intervention Programme and the role of mediation in the programme to address underachievement by providing the necessary academic building blocks for students to return to mainstream. This study draws on the theories of Vygotsky and Feuerstein to investigate how mediation can be studied in an academic development programme, using a collective case study with qualitative and quantitative research methods
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
Exploring factors influencing competencies of scientific laboratory technicians and recommendations for improvement: A case study of a Scientific Laboratory based in a resource constraint setting
Get PDFResearch in Africa and on African data is booming, seeing an increase in scientific projects conducted and products created. This significantly contributes to the bioeconomy, where establishing scientific laboratories is a key strategy. It is essential to ensure that there is competency, that is, the necessary knowledge applied when designing and implementing solutions. This produces quality outputs that attract funding and business. Technicians are key as they complete core functions that directly affect outputs. There are limited studies on scientific laboratory technicians in resource constraint settings, handling diverse projects, that focus on understanding underlying factors influencing their competencies. Influences were investigated in a transdisciplinary manner. Learning theories focused on how the adults learn (Knowles), their self-efficacy (Bandura) and their Community of Practice (Lave and Wenger). While Systems theory overlayed and focused on what a viable system should look like, Viable Systems Model (Beer). Focus groups were conducted with the technicians, managers, and senior managers. From thematic analysis, eight themes emerged: Communication, Contextual factors, Education, Hierarchy, Interpersonal, Leadership, Operational systems, and Organizational climate/culture. A central theme underlying all of the themes was Leadership, that is, how leadership influences and impacts the other themes. Surveys were conducted to triangulate findings and determine central tendencies. Key overall findings were from the senior managers. They sit in a significant position that influences the emerged themes and can action change. Although the senior managers understood and valued the different influences, they were less aware of the underlying factors, interactions, and resulting adverse effects. Overall recommendations were related to training and awareness at different hierarchy levels. For technicians and managers, frame how to differentiate between them viewing themselves as incompetent versus being in a hindering environment. For managers and senior managers, frame how different factors interact and influence technicians' competencies and resulting adverse effects. In Africa and abroad, this is replicable in scientific laboratories that conduct diverse scientific work, and this aids in developing the necessary contextual leadership training
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
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
Negotiation of learning and identity among first-year medical students
No full textThis is an Accepted Manuscript of an article published by Taylor & Francis in Teaching in Higher Education on 2 January 2013 available online: http://www.tandfonline.com/10.1080/13562517.2012.753050.The demand for medical schools to produce competent doctors to meet health needs in South Africa has increased. In response to this challenge, the Faculty of Health Sciences at a relatively elite university introduced a problem-based, socially relevant curriculum in 2002. The classroom environment is designed to facilitate a learning context where students from diverse backgrounds engage critically and learn from each other. This study draws on data from a larger qualitative case study to describe how a group of 'black' students who failed their first semester experienced the school–university transition. Drawing on post-structuralist theory, this article analyses how the students negotiated learning and identity. The argument is made that the students re-positioned themselves in deficit, outsider subject positions in order to survive their first year. This article ends with a consideration of the implications for developing a learning environment which recognises difference and fosters diversity
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
