Prospects and Challenges to ICT Adoption in Teaching and Learning at Rural South African Universities: A Systematic Review
Get PDFThis study aimed to systematically review the prospects and challenges associated with adopting Information and Communication Technology (ICT) in teaching and learning at rural universities in South Africa. To achieve this aim, a systematic review methodology was employed. The systematic review findings revealed a multifaceted landscape wherein opportunities for enhancing education through ICT exist alongside significant challenges. Prospects include the potential for technology to bridge educational gaps, increase accessibility, and provide innovative learning experiences. However, challenges such as inadequate infrastructure, limited connectivity, and varying levels of digital literacy pose significant impediments. The study emphasizes the need for targeted interventions to address these challenges, including infrastructure development, capacity building, and localized content creation. Additionally, recommendations for flexible learning models and collaborative partnerships are outlined to facilitate effective ICT adoption in the unique context of rural South African universities. Continuous research and evaluation are advocated to inform future strategies and ensure sustainable improvements in rural education through ICT integration
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
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
Exploring the Factors Enhancing Marketability of Coastal Agricultural Products in Rural South Africa
No full textThis study explores the dynamics of marketing agricultural products in the coastal regions of the Eastern Cape, South Africa, through an analysis of existing literature and empirical data collected from selected participants to model farmers’ marketing experiences and identifies an improvement pathway. This study aims to enhance the understanding of the factors that inhibit and enable the marketability of coastal agricultural products. Employing a causal relationship research methodology, this paper reviewed the current situation through a bottom-up approach, providing valuable insights for policymakers, interventionists, researchers, and practitioners who aim to support rural coastal agricultural growth and livelihood enhancement in the Eastern Cape. Data were collected from 215 participants from the sample of 4212 registered coastal small-scale farms in the Eastern Cape through a multi-staged sampling procedure. The findings through Path analysis empirically revealed that technological resources, efficient supply chain systems, supportive government policies, and unlimited market access significantly enhance the marketability of coastal agricultural products. The study recommends addressing challenges such as inadequate infrastructure, stringent regulatory requirements, and the effects of climate change, which is essential for advancing the marketability of coastal agricultural products
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
