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
Exploring Competence Based Education (CBE) in Rural Secondary Schools in Tanzania: English Language Teachers’ Conceptions and Experiences
Get PDFThis study aimed at getting an insight on the implementation of Competence Based Education in Tanzania (CBE) in Tanzania. A study was conducted in Changchun, Jilin in China due to limited time the researcher had. The study was guided by the following research objective; specifically this study did the following; to assess the knowledge that rural secondary school teachers of English have on CBE, to explore the extent they use CBE in their day to day practice and to identify challenges that they encounter in the course of implementing CBE. Three research questions guided the study; what do rural secondary school teachers understand about CBE? To what extent do they use it in their day to day teaching practice? What are rural secondary school teachers’ perceptions of the challenges in implementing CBE in English subject? The study employed a qualitative research design, semi structured interview guide was used as a tool for data collection. It involved a study sample of three Tanzanian students. The findings revealed that teachers have knowledge of CBE and the mostly preferred teaching techniques are question and answers and occasionally lecturing. Others include problem solving and project development. However, it was revealed that no changes have been made in terms of assessments. Moreover, challenges of big class sizes, limited time and lack of teaching resources such as textbooks were seen as hindering the implementation process. It was recommended that there has to be a top-down approach in changes of the curriculum in order to adhere to the mandated education philosophy and the new teaching paradigm.

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
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
THE ROLE OF ENGLISH LANGUAGE TEACHER COLLABORATIONS IN EFFECTIVE CURRICULUM IMPLEMENTATION: A CASE OF SECONDARY SCHOOL TEACHERS IN TANGA REGION, TANZANIA
Get PDFThis paper intended to explore the role of English language teacher collaborations in curriculum implementation. Literatures revealed that availability of workshops and conferences alone in curriculum implementation have not proved to be fruitful in letting teachers change their teaching practices. The purpose of this study therefore was to examine the role of English language teacher collaborations in the process of curriculum implementation in ordinary secondary school. The study adopted a qualitative research design where in depth interviews were used for data collection. The study was guided by two research questions; what roles do teacher collaborations play in curriculum implementation and in what ways are teacher collaborations important in curriculum implementation. The study was conducted in Tanga region in 3 districts namely; Tanga municipal, Muheza and Korogwe. The sample included 8 ordinary secondary school teachers who were selected using snowball sampling procedure. The criterion for participating in the study was 10 years teaching experience. Findings revealed that English language teacher collaboration is an important aspect in adhering to changes in the day to day teaching practice and effective curriculum implementation. Furthermore, most teachers are used to a bound collaboration which always ends within the department in a respective school. The study concluded that open collaborations are more important in the teaching career so that teachers become open minded and absorbs new ways of teaching. The study recommends for school to school, district to district and region to region collaborations to enable teachers open up their minds and enhance their teaching career. Article visualizations
THE IMPACT OF SOCIAL NETWORKING SITES (SNSS) ON STUDENTS’ SOCIAL INTERACTION
Get PDFThis study explored the impact of Social Networking Sites (SNSs) on students’ social interaction at Northeast Normal University in China. The study was guided by three research questions; what are the levels of SNS time use and social connectedness in terms of gender?, what are the differences of university students SNS time use and social connectedness and what is the relationship between SNS time use and social connectedness. It involved a total sample of 79 students from various faculties and majors who were randomly selected. Data was collected by using a questionnaire which had two scales; SNSs time use scale and social connectedness scale. Findings revealed that there are significant differences on number of years one has engaged himself with SNSs, number of friends that one has and amount of hours that one spends using SNSs with SNSs time use scale. There is also significant difference on number of SNSs applications that one has with social connectedness. The study also revealed a positive correlation between SNSs time use and social connectedness. No significant differences were found among gender, age and faculty with social connectedness. It was recommended that further research should be conducted on the same using more variables and a wider dimension. Article visualizations
