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
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
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 Effect of Some Constraints on Mathematics Instructors’ Problem Solving Practices: Universities in Amhara Region in Focus
No full textThis study was designed to examine the effect of perceived constraints on four universities mathematics department instructors’ classroom practices of problem solving in teaching mathematics. To this end, the target population of the study includes mathematics instructors in the Amhara Regional state universities. From a total of seven functioning universities, four universities were selected using simple random sampling technique. The four universities’ respective mathematics departments were selected using purposive sampling techniques. Then, all mathematics instructors of the four universities selected using comprehensive sampling technique were samples of thisstudy. Five mathematics instructors from each of the four universities were selected using simple random sampling technique for classroom observation and similarly three instrctors from each of the sample universities were selected using simple random sampling technique for interviewing. Questionnaire, classroom observation, and semi structured interviews were used as the basic instruments for collecting data. The quantitative data were analysed using one sample t-test whereas the qualitative one was analysed using narration.The findings showed that teachers have claimed to have adequate experience concerning problem-solving teaching in mathematics. This further shows that teachers possess the theories and their application of indirect instruction, organzing mathematics lessons, classroom management using assessment techniques. Teachers have also explained that the training has helped them to relate it with their actual teaching strategies, to organize their lessons into problem-solving approach, to manage the classroom and to align assessment techniques in line with problem-solving approach. In spite of the presence of constraints in implementing problem- solving method at an average level, their obstruction effect was not significant. The findings also implied that there are opportunities to implement problem-solving approach in mathematics in the universities to the expected level. In spite of the existence of opportunities at an adequate level, their extent of availability was found insignificant. In relation to the findings of the study, recommendations are forwarded
The Support Rendered from Teacher Education Policies to Prospective Teachers’ Multicultural Competence Development in Ethiopia
Full text linkThis study was designed to examine the support rendered from teacher education policies to prospective teachers’ multicultural competence development in Ethiopia. The major sources of data were basic policy documents (i.e., National Constitution, Higher Education Proclamation, Education and Training Policy, and Strategic Plan Documents) related to the pre-service teacher education program. Policy documents were selected using purposive sampling technique. And, data for these policy documents were collected through document analysis technique. This technique is supported by a coding sheet prepared using multicultural attributes and how they are manifested in the four preceding policy documents. Document analysis data were reported in words following themes made vis-àvis the research questions of this study. The fi ndings of the study confi rmed that basic policy documents reviewed seem to have given adequate contextual support to prospective teachers’ multicultural development, as policies guide the actual practice at schools
