    E-learning is substantially becoming a popular effective learning approach within greater academic settings due to high use of web systems in learning. E-learning involves utilization of information and communication technology (ICT) to improve and help teaching and learning. The aim of this study was to estimate the relationship between e-learning and students’ academic achievement in higher education. Based on systematic sampling approach, a sample of 15 research studies conducted between 2010 and 2013 were used in computation of results using the Cohen’s model. The computed results (= 0.782) indicate that ICT has a statistically significant positive impact on e-learning based students’ academic achievements. The findings indicate that ICT has a significant positive impact on students’ educational overall academic achievements. Keywords: E-learning, information and communication technology (ICT), students’ academic achievemen

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    Factors Impeding Global Human Resource Management Transformation: The Case of South African Multi-National Corporations

    The objective of this research was to explore the current challenges experienced in global human resource during the period 2010-2014. Purposive sampling was used to select 25 human resource specialists of global multi-national corporations (MNCs) and gather data on their views regarding challenges in global human resource transformation. A standardized structured questionnaire was used to collect data on the respondents’ level of agreement regarding the prevalence of global human resource management challenges. The Keiser-Meyer-Olkin (KMO) measure of sampling adequacy (MSA) and Cronbach’s alpha values for discrete dimensions of global human resource management transformation challenges show that the data used for the research was structurally valid and reliable. Results derived from frequencies and descriptive statistics indicate that implementation of change, recruitment and selection of employees, performance management and review of labour laws of host countries, currently remain as global human resource transformation challenges. Based on the results computed from the Principal Component Analysis (PCA), strategic talent management emerged as the most significant challenge in global human resource transformation; followed by strategic workforce planning, global alignment of human resource policies and resistance to change. Keywords: global, human resource management, transformation, challenges, MNCs

    Dispelling the Myths Behind First-author Citation Counts

    Get PDF
    We 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

    We 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

    Social Inclusivity, Integration and the Fourth Industrial Revolution in South African Universities: Evidence from Vaal University of Technology

    No full text
    Introduction: The swift strides of the fourth industrial revolution (4IR) and its entrenched emerging technologies are expected to increase significantly, leading to significant technological transformation and socio-economic change. The emerging 4IR technologies could bring substantial economic growth and welfare benefits in sub-Saharan Africa and social and economic disruption. There are emerging concerns that the rising pace of 4IR could widen inequality if counterbalancing policies are not adopted. This implies that coping with the 4IR transformation may require a holistic approach encompassing sustainable social solutions and not just technological ones. To meet and extend their understanding of the curriculum\u27s objectives and improve their overall comprehension, students need to be able to use various digital tools. This study examines the role of the adoption of 4IR technologies in fostering social inclusivity and integration in the South African context. Methodology: Drawing from the technological integration models, the current study argues that 4IR plays a crucial role in transforming the inclusivity and integration of learners, such as those living with disabilities and those from previously disadvantaged backgrounds. Technology integration models are theoretically constructed models that are meant to assist educators in planning technology integration more profoundly. Research was conducted on 203 students from different faculties selected using simple random sampling. Data was collected using an online questionnaire powered by Google Forms and analysed through structural equation modelling in SmartPLS 4. Results: An evaluation of the results obtained in this study reveals a positive contribution of 4IR towards the general concept of inclusion as defined by the extent of accommodating different disabilities and backgrounds in social activities. The analysis also demonstrated the importance of 4IR in integrating learners in mainstream classrooms and significant strides in eliminating special needs classes. Conclusion/- and Recommendations: The paper concludes with recommendations for developing 4IR adoption strategies by universities in South Africa to bring about attitudinal change and formulate genuinely inclusive and integrated practices
