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
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
Teaching Gases through Problem-based Learning
No full textThe purpose of this study was to investigate not only the applicability of the method of Problem-Based Learning (PBL) to the lesson subject of “Gasses” within the scope of the 9th grade course of Chemistry in Hakkari Gazi High School but also the influence of this method on the students' achievement levels in chemistry and on their motivation and attitudes towards chemistry. For this purpose, the mixed method, which involves both quantitative and qualitative designs, was applied. In the study, the embedded design, one of the mixed methods of research, was used. The research sample included 56 students taking the course of Chemistry in Hakkâri Gazi High School. In the study, the students were divided into two groups: experimental group (n=27) and control group (n= 29). The PBL method was applied to the experimental group. The application was carried out in the Spring Term of the academic year of 2014-2015. Before and after the application, an achievement test to measure the students' levels of success in the lesson subject of "Gasses", attitude scale towards chemistry, motivation scale for chemistry, scenario, reports and observation forms were used. As the study dominantly had a quantitative design, quantitative data collection tools were used. In order to support the quantitative data collection tools and to gather more detailed data, the observation method was also used as a data collection tool. For the analysis of the quantitative data, package software of SPSS 18 was used. As for the analysis of the observation data, content analysis was conducted. The results revealed a significant difference between the achievement levels of the experimental and control groups. However, no significant difference was found between the experimental and control groups regarding their motivation and attitudes. In the light of the observations recorded, it could be stated that the PBL method increased the students' intragroup and intergroup communication skills, their self-confidence and their skills in making presentations and reporting
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
IDENTIFYING BARRIERS WHEN TEACHING SCIENCE AND MATHEMATICS IN LOW ECONOMY REGIONS: SWANSEA AND HAKKARI AS CASE STUDIES
No full textThe purpose of this research was to identify the barriers that upper-secondary school science and mathematics teachers face during the teaching process in economically disadvantaged regions (Hakkari, Turkey and Swansea, UK). The research design was comparative case research and pursues qualitative methodological approach in collecting and analyzing the data about the barriers that teachers are encountering during the teaching process. The research sample consisted of 24 science and mathematics teachers from different upper-secondary schools in Hakkari and Swansea. Semi-structured interview forms, were developed and employed to collect the data. The thematic analysis was used to analyze the obtained data. The results revealed different categories in understanding the situations that science and mathematics teachers confront in both cases; student-related issues, pedagogical issues, teachers’ lack of subject knowledge and socio-economic and cultural-based issues. As student-based barriers, lack of prior knowledge, students`attention span, and interest; and regarding teachers-based barriers, teachers` lack of class management and communication skills, and lack of student-centered methods found as similar barriers. Language and socio-economical problems were also shared barriers for both cities. In addition to those barriers, political and family-based issues which hindered educational attainment found as the main barriers by science and mathematics teachers in Hakkari.

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
