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
Sustaining Communities of Learning and Practice in Kenyan Universities: Building Resilient and Inclusive Open Education Systems
No full textThe transformation of higher education in Kenya is increasingly driven by the need for sustainable, resilient, and inclusive learning environment. Communities of Learning and Practice (CoLP) have emerged as vital structures that support collaborative knowledge sharing, innovation, and continuous professional development among educators and students. This paper examines the role of CoLP in building resilient and inclusive Open Education Systems (OES), identifies key challenges that hinder the sustainability of CoLP and proposes strategies for strengthening CoLP, within Kenyan universities. The study is anchored on Wenger’s Social Learning Theory which posits that learning occurs through active participation in social communities and engagement in shared practices. A descriptive survey research design was used to collect data from university teaching staff in Kenya. The study explored faculty perceptions, experiences, and suggestions regarding Communities of Learning and Practice (CoLP) and Open Education Systems (OES). Based on the findings, the study recommends investing in robust digital infrastructure, implementing targeted faculty development programs, providing recognition and incentives for CoLP participation, and developing supportive institutional policies. This research provides valuable insights for educators, policymakers, and researchers interested in advancing open and inclusive education in Kenya and beyond.

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
Creativity Level in Chemistry Education by Gender Among Secondary School Students in Kenya
Get PDFEducation is the most critical ingredient in a country’s development process in the social, economic and political realms. Kenya in its vision 2030 hopes to be transformed into a newly industrialised, middle-income country providing a high quality of life to all its citizens in a clean and secure environment by the year 2030.To realise this vision, the country needs to develop through its education system, manpower that is trained to think creatively. The role of Chemistry in the development of the scientific base of a country cannot be over emphasized and Kenya is no exception. Kenya’s secondary school Chemistry, Physics and Biology syllabi recommend the acquisition of creative skills by students. Few studies have been carried out in Kenya with regard to scientific creativity in secondary schools. Studies in Physics and Biology have shown that the level of scientific creativity is low and is influenced by such factors as gender and knowledge. It is not clear whether the low levels on scientific creativity found in Biology and Physics also apply to Chemistry hence there is need to determine the level of scientific creativity in Chemistry and factors influencing the level. Therefore, the purpose of this study was to determine the level of scientific creativity in Chemistry education in Kenya. The study went ahead to find out whether there are gender differences in scientific creativity in chemistry as a whole and in the different aspects of scientific creativity namely; sensitivity to a problem, flexibility, recognition of relationships and planning for investigation. The study involved ex-post facto research with causal-comparative and correlational designs. The population of the study was all Form Three students in National Secondary Schools in Nairobi and Kiambu Counties and all Form Three students in District Secondary Schools in Muranga and Kajiado Counties in Kenya. A sample of 16 schools (4 Boys’ and 4 Girls’ National schools and 4 Boys’ and 4 Girls’ District schools) were involved in this study. National schools were selected through random sampling, while the County schools selection were through purposive random sampling. Participating Form Three stream (class) in the schools were selected through stratified random sampling. A total of 672 students, (275 boys and 397 girls) were involved in the study. Data were collected using the Chemistry Scientific Creativity Test (CSCT) instrument. Quantitative data from CSCQ was analysed using t-test. Chi-square was used to test for the relation between the two variables; gender and scientific creativity in Chemistry. Tests of significance were done at 0.05 alpha level. The findings of this study indicated that the level of scientific creativity in chemistry education is low. The findings further indicated that the level of scientific creativity in Chemistry was not gender dependent.

University Students’ Preferences, Perception and Challenges of Online Learning. A Case of University of Kabianga, Kenya
Get PDFPCF10 Sub-theme: Building Resilience // An online class is a system where students can learn, discuss issues with fellow students, clarify doubts with teachers, share material and assess academic progress through the help of computer and internet-oriented technologies. Online learning (OL) had been ignored in many parts of developing countries due to challenges such as lack of access and affordability of Information Communication Technology (ICT). Since the breakout of Covid–19 pandemic in 2020, lockdowns became a challenging situation for everyone and in every sector of the economy, education included. As a result online classes are gaining so much importance all over the world, and has shifted the thought of educators that “Online class is Optional” to “Online class is necessary”. This study looked at students’ preferences, perception and challenges during newly introduced OL at University of Kabianga (UoK). The study is anchored on connectivism theory of learning. Descriptive quantitative and qualitative research design was used and was conducted through an online survey. Study population was 600 2nd year student at UOK, who were taking OL for their first time due to Covid-19 pandemic. Sample size was 240 2nd year students randomly selected. Data was analyzed using descriptive and inferential statistics. Findings indicate that learners preferred smart phones as their learning device, and blended OL. Learners have positive perception towards OL despite citing a number of challenges experienced during OL, such as lack of digital devices, poor and unreliable internet, and power connectivity, unconducive OL environment at campus and lack of digital skills needed for OL. // Paper ID 607
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
