Distance and Online learning in Nigerian Open and Distance Learning Institutions; Learners’ Perspective
Get PDFThis study examined the view of Science Education learners at Distance Learning Institute (DLI), University of Lagos and the National Open University of Nigeria (NOUN) about Distance and online learning. A descriptive survey research design was adopted. A researcher-designed questionnaire with reliability co-efficient of 0.78 was employed. Mean score and standard deviation (SD) answered the research questions elicited from two hundred and ten (210) respondents while t-test analyzed the hypotheses. The result of the hypotheses, revealed no significant difference in the perception by learners based on gender. The findings revealed that, study materials were not all available at the beginning of the academic year. Learners prefer their lecture modules in audio and video formats, teleconferencing and live streaming than in-prints. The LMS does not accommodate virtual laboratory for practical, which is essential for Science Education students. The institutions’ managements are encouraged to proffer solutions to these identified challenges for learners’ motivation
E-Skills and Digital Literacy: An Investigation into the Perceived Competencies of Distance Learning Students in the University of Lagos
Get PDFIt is currently of utmost importance to ensure that students in higher education acquire and employ the digital literacy skills they will require to excel in their academic endeavours and personal lives. This research sought to find out students’ perceptions of their digital literacy and e-skills and the digital tools they utilise on a daily basis. The Distance Learners at the University of Lagos were randomly sampled (stratified) to respond to the researcher-designed questionnaires, to elicit responses from the learners. 354 respondents being female and 306 being males. A Cronbach alpha value of 0.78 was obtained. Analysis of the research questions show that there is a significant gap between the perceived importance of e-skills and digital literacy competencies and their actual usage. The findings suggest that there may be a need for greater focus on developing e-skills and digital literacy competencies among distance learning students. For instance, 64.4% of respondents use technology very frequently in their coursework. Institutions and educators may need to provide training and support to help students develop these skills. Additionally, students may need to prioritize their own learning of these skills and seek out resources and opportunities to develop themselves. However, the negative perceptions of a small percentage of respondents suggest that there may be areas where improvements could be made. Institutions and educators may need to continually evaluate their support programs to ensure they are meeting the needs of students, and work to address any areas where support may be lacking.

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
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
