    PCF10 Sub-theme: Fostering Lifelong Learning // As the extension of the lockdown period of Covid-19 that was declared as a pandemic persisted, the problem of conducting face-to-face teaching-learning process was overcome with online classes. Examinations that are used to make decisions about an individual learner’s progress could not hold as the pandemic continued. The National Open University of Nigeria (NOUN) being an open and distance learning institution came up with the resolution of conducting on-demand virtual examinations for distance learners in 2020 but a few numbers of them participated and this called for attention. The study investigated perception of distance learners of the NOUN on the virtual examinations. The descriptive survey design was adopted and 247 participants of the NOUN were randomly sampled in all the six geo-political zones. Two research questions were stated to guide the study. Data were collected using a survey questionnaire. Reliability and validity of the instrument were ensured. Data obtained were analysed using descriptive and inferential statistics. Findings revealed that majority of the respondents perceived the virtual examination to be highly beneficial, secure and credible and devoid of missing scores, immoral and unethical practices. It was recommended that university authorities should embrace the new norm of global digital development to be relevant for quality virtual examinations. // Paper ID 898

    Gender and Entry Background Differences in Postgraduate Distance Learners’ Achievement in the Field of Educational Technology

    Several factors have been attributed to learners’ underachievement in postgraduate programmes. Two of such factors are gender and entry background of postgraduate distance learners which previous studies have identified in isolation of one another. No previous studies have been reported to have investigated a combination of gender and entry background differences in educational technology. The present study, therefore, investigated the influence of gender and entry background of postgraduate distance learners’ achievement in educational technology. The ex-post facto research design was adopted. Three hundred and twenty-three postgraduate distance learners who registered and sat for examinations of Master of Education in Educational Technology of National Open University of Nigeria, during the first semester of 2019_1 of 2018/2019 academic session were purposively selected from 74 study centres. The participants were made up of 215 males and 108 females. Three null hypotheses were formulated to guide the study and tested at .05 level of significance. The results of participants in 2019_1 first semester were analysed using t-test and analysis of variance (ANOVA). There was a significant difference in the mean achievement scores of male and female postgraduate distance learners in educational technology in favour of male distance learners while no significant difference was established in respect of postgraduate distance learners’ entry background. The implications of this study are that gender difference is a factor of prediction to academic achievement in educational technology but entry background does not influence postgraduate distance learners’ achievement in courses. Recommendations were made among others that there is need to create co-operative learning activities sensitive to preferences of female distance learners

    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

    Get PDF
    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

    Dispelling the Myths Behind First-author Citation Counts

    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
