    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

    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

    An ethnomethodological analysis of students’ ways of working with algebraic fractions in high-stakes examinations: the case of level 3 mathematics students at technical and vocational education and training (tvet) colleges

    Philosophiae Doctor - PhDThe study investigates the National Certificate Vocational (NCV) Level 3 students’ ways of working with rational algebraic fractions in a high-stakes examination. An ethnomethodological analysis was used to reveal the textures of examinees’ work. Ways of working in this study refer to how examinees deal with algebraic fractions when simplifying them, including even those elements of their work, which are rough work in the sit-down examination. Ethnomethodology is the study of ordinary actions by ordinary members of society. Ordinary action means that members regularly and recurrently do it with such automaticity that it is given little thought. Ethnomethodology is the study of how people use common sense, procedures, and considerations to gain an understanding of everyday situations (Garfinkel, 1967). In the context of mathematics education, ethnomethodology seeks to understand how examinees construe, construct and orient themselves to these norms that are usually seen but unnoticed (Garfinkel 1967). The study is premised on a qualitative research paradigm that focuses on studying situations in their natural settings and applying an interpretive perspective. Data were collected from two colleges using students’ examination scripts for the end-of-year NCV L3 mathematics exams. Guba and Lincoln’s (1985) concepts of trustworthiness, credibility, transferability, dependability, and confirmability were used. The study sought to ensure ethical principles were followed by applying to each college for permission to conduct research and collect data. Permission was granted. Ethical clearance from the University of the Western Cape was obtained before conducting any data collection. The researcher ensured confidentiality and the anonymity of the participants’ scripts. The examination guidelines require that the examination scripts and mark sheets be kept at an institution for verification and cases of appeal. The institution keeps examinees’ examination scripts, which are confidential. The researcher ensured that scripts did not leave the college and ensured the confidentiality of their information by making copies of the scripts and keeping the copies safe. The study poses no harm to the participants or the colleges

    Investigating the effects of continuous professional development on ICT integration in the classroom of Foundation Phase Mathematics

    Magister Educationis - MEdThe use of technology is becoming the norm in the 21st century classroom to enhance teaching and learning. This rapid move to incorporate technology in the classroom brought the need for teachers to be upskilled on the use of technology as a pedagogical tool. Through this study the researcher sought to investigate the effects that Continuous Professional Development (CPD) has on Information and Communications Technology (ICT) integration in the classroom, with a specific focus on the teaching and learning of mathematics in the Foundation Phase. The mixed method research design will be underpinned by the conceptual approach of the Technological Pedagogical Content Knowledge (TPACK) and Substitution, Augmentation, Modification and Redefinition (SAMR) frameworks and supported by a constructivist learning theory approach to the teaching and learning of mathematics

    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
