Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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

Ensino, Aprendizagem e Avaliação durante A Covid-19: Desafios e Perspectivas da Ert da Universidade de Ibadan
Full text linkThe Covid-19 pandemic has brought extraordinary challenges and has affected the educational sectors in all ramifications. This, therefore calls for the need to sustain and provide quality education despite its challenges and forced many institutions to reposition their educational practices which predominantly adopted the conventional methods of teaching and learning, as well as assessment which was on venue-based and restricted in terms of online accessibility, swiftness, assessment and materials interaction. In the new normal period, there is much emphasize to reposition our institutions for teaching and learning in terms of the mode of instruction and assessment. Many countries, Nigeria inclusive were forced to migrate to a more robust innovative online teaching and learning, and different forms of online instruction and assessment using diverse platforms such as Emergence Remote Teaching(ERT), google meet, zoom, Microsoft team and others. These online teaching platforms have implications for lecturer-student interaction, satisfaction, engagement, and success in curriculum planning and implementation issues. Seventy-five lecturers in the faculty of Education from the 11 departments partake in the study. Questionnaires and structured interviews were used to collect data. Data collected were analyzed using the descriptive statistics of mean, while the qualitative data was content analyzed. This study identified the challenges of teaching staff and students in teaching and learning using ERT, University of Ibadan as a case study. Challenges idented includes: internet connectivity, technological experiences, power supply,and lack of access to reliable internet connection .The perceived benefitswere a reduction in transportation costs, effective distance learning, stability in communication and lecturers\u27 familiarisation with online emerging technology. ERT platforms should be designed with engaging and interactive content, instructors and students\u27 learning activities to maintain students’ interest during the lesson session were recommended.A pandemia da Covid-19 trouxe desafios extraordinários e afetou os setores educacionais em todos os aspectos. Isso, portanto, requer a necessidade de sustentar e fornecer educação de qualidade apesar de seus desafios e forçou muitas instituições a reposicionar suas práticas educacionais, que predominantemente adotavam os métodos convencionais de ensino e aprendizagem, bem como avaliação que era baseada em local e restrita em termos de acessibilidade online, agilidade, avaliação e interação de materiais. No período do "novo normal", há muito ênfase em reposicionar nossas instituições para o ensino e a aprendizagem em termos do modo de instrução e avaliação. Muitos países, incluindo a Nigéria, foram forçados a migrar para um ensino e aprendizagem online mais robustos e inovadores, e diferentes formas de instrução e avaliação online utilizando diversas plataformas como Ensino Remoto Emergencial (ERT), Google Meet, Zoom, Microsoft Teams e outros. Essas plataformas de ensino online têm implicações para a interação entre professores e alunos, satisfação, envolvimento e sucesso em questões de planejamento e implementação curricular. Setenta e cinco professores da faculdade de Educação dos 11 departamentos participaram do estudo. Questionários e entrevistas estruturadas foram usados para coletar dados. Os dados coletados foram analisados usando as estatísticas descritivas de média, enquanto os dados qualitativos foram analisados de forma de conteúdo. Este estudo identificou os desafios dos professores e alunos no ensino e aprendizagem usando a ERT, Universidade de Ibadan como estudo de caso. Os desafios identificados incluem: conectividade à Internet, experiências tecnológicas, fornecimento de energia e falta de acesso a uma conexão à Internet confiável. Os benefícios percebidos foram uma redução nos custos de transporte, aprendizagem eficaz à distância, estabilidade na comunicação e familiarização dos professores com a tecnologia online emergente. Recomendou-se que as plataformas de ERT sejam projetadas com conteúdo envolvente e interativo, atividades de aprendizagem de instrutores e alunos para manter o interesse dos alunos durante a sessão de aula
Variations on the Author
Full text link“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
Full text linkWe 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
Full text linkWe 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
EFFECTS OF SUDOKU PUZZLES ON PRIMARY SCHOOL PUPILS’ ACHIEVEMENT IN MATHEMATICS IN OYO STATE, NIGERIA
No full textMathematics forms the bedrock of cognitive development for students logical reasoning and problem-solving abilities. However, the high failure rate among students in the subject remains a significant concern. Previous studies on students’ achievement in mathematics concentrated more on cooperative-based interventions than on game-based strategy using sudoku puzzles. Therefore, this study investigated the effects of sudoku puzzles on primary school pupils’ learning achievement in mathematics in Oyo state, Nigeria. It also examined the moderating effect of gender on dependent measures. The pretest-posttest control group quasi-experimental design with a 2x2 factorial matrix was utilised. The instruments used were the Pupils Mathematics Achievement Test (r=0.76) and the Teachers’ Instructional Guides. The treatment lasted six weeks. Data was analysed using Analysis of covariance and Scheffe post-hoc analysis at p<0.05. There was a significant two-way interaction effect of treatment and gender on pupils’ achievement in mathematics (F1,109) =28.89, partial η2=0.042). Although, the boys (19.67) benefited more from the treatment package than the girls (19.12), it was not significant. There were no significant main of treatment on pupils’ achievement. Sudoku puzzles instructional strategy improved pupils’ achievement in mathematics in Oyo state, Nigeria. Mathematics teachers in primary schools should adopt sudoku in teaching mathematics
