    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

    Cigdemoglu, Ceyhan/0000-0001-5389-5790The present study specifically focuses on science teachers' views about scientific inquiry and their use of scientific inquiry in their lesson plans, which were prepared at a professional development workshop designed for better utilization of science centers (SCs). As an impact evaluation research, qualitative data was collected from 41 purposively selected volunteer science teachers. The project team provided the participants with intense instruction in inquiry, and fostered them to learn nature of science and nature of scientific inquiry explicitly. The participants designed lesson plans that integrate school science curricula with exhibits at SCs before and after the workshop. An open-ended questionnaire about the views about scientific inquiry (VASI) was administered before and after the workshop, and teachers' post-lesson plans were analyzed to detect the presence of scientific inquiry aspects. The majority of teachers exhibited improved views about scientific inquiry based on the VASI instrument. Also, lesson plan analyses indicated that teachers, who showed more improvement in VASI, included more scientific inquiry (SI) elements in their post-lesson plans. It was observed that science teachers' lesson plans are limited in terms of teaching science in line with real scientific inquiries in SCs to make students learn about the nature of scientific inquiry while learning science. Only two groups embedded SI properly in the SC-oriented lesson plans, and teachers rather used inquiry-based methods of teaching (e.g., argumentation, predict-observe-explain) and process skills (e.g., questioning, explanations). Accordingly, further studies are suggested to develop a specific pedagogical content knowledge framework for teaching with/in SCs.Scientific and Technological Research Council of Turkey [114K646]This study is funded by The Scientific and Technological Research Council of Turkey under project number 114K646.

    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

    Analysis of High School Physics, Chemistry and Biology Curriculums in terms of Scientific Literacy Themes

    No full text
    The purpose of this study is to analyze 9th grade physics, chemistry and biology curriculums, which were implemented by the Ministry of Education since the academic year 2008-2009, in terms of scientific literacy themes and the balance of these themes and also to examine the quality of statements about objectives. Physics, chemistry, and biology curriculums were examined and coded independently by two coders who were faculty members in the branch of chemistry, physics and biology education. Cohen's kappa statistic results showed that there was high degree of consistency between coders. Analysis results revealed that the theme the knowledge of science in the chemistry curriculum and the theme the investigative nature of science in the physics and biology curriculums were well emphasized; however, the theme the science as a way of thinking was not adequately emphasized in each of the three curriculums. The findings of the study show that nature of science should be more emphasized in science curriculum to help each of citizens in our country become lifelong learners and have an adequate level of scientific literacy

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    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
