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
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

Learning in Multilingual Contexts: Language Policies, Cross-Linguistic Transfer, and Reading Interventions
No full textThe proportion of children across the world who have access to basic education through formal schooling has never been as high as it is today. Surveys of literacy and numeracy skills in low- and middle-income countries, however, regularly highlight low levels of learning, even for young people with several years of formal schooling. Among the structural issues faced by school systems in low- and middle-income countries experiencing rapid increases in enrollment, linguistic heterogeneity of communities and countries stands out as it poses both a threat and opportunity to quality instruction.
This dissertation is organized in three papers and aims to explore: (i) ways in which language in education policies are designed, implemented, and understood; (ii) whether cross-linguistic transfer theories apply in a new context; and (iii) heterogeneity across teachers and schools of the impact in a bilingual literacy intervention.
The first paper describes the multi-faceted factors that policymakers take into account when designing language in education policies, and presents a framework for analyzing these policies at the community, regional or state-level. The second paper uses structural equation modeling to test cross-linguistic transfer in a sample of second-grade students in Uganda. Findings suggest children in second grade have developed common decoding skills across two languages, and those staring to learn in their first language can transfer reading comprehension skills to the second. The third paper in this dissertation explores the impact of a literacy intervention in Kiswahili and English in urban public and private nonformal schools in Kenya. The study exploits the random assignment of schools to an intervention to identify whether the impact of an intervention differed across types of teachers and schools. The study finds large average gains in literacy skills in English and Kiswahili and no differences in average impact across teacher characteristics. In contrast, the school characteristics moderate the impact of the intervention on higher-level skills (word reading and comprehension). This work contributes to support the process of designing and implementing language policies in schools focused on inclusion and equity.Education Policy, Leadership, and Instructional Practic
