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
Exploring the Role of Family-School Partnerships in School Choice
Get PDFParental access to useful information about schools continues to be a structural barrier that limits the equity potential of school choice programs. While “information interventions” or simplified and readable knowledge resources show promise for counteracting information disparities between families, this line of research has provided limited insight on the particular preferences and needs of parents or the value of person-to-person interpretive assistance in school decisions. This exploratory study uses qualitative methods to investigate parent-school collaboration for the purpose of school selection in Washington, D.C. Drawing on a social capital framework, this study analyzes information transactions from parents’ perspectives to clarify ways in which school personnel currently function as liaisons of choice. Findings from this study indicate future opportunities for districts to improve the outcome of school choice through better training of school and district personnel
Unwritten Ground Rules of School Choice: Excavating Capital as a Regulator of Access to Educational Goods
Get PDFDistrict leaders in school choice contexts tend to overlook the many hidden costs of selecting schools in terms of mobility, time, liquidity, and labor. Meanwhile, a body of literature on school choice policies and cultural, social, and political capital shows that middle-class parents use the resources they possess to get the school access they want. In this study, I critically examine the complex interplay between school choice policies and forms of capital. This analysis extends our empirical understanding of the political dimensions of families’ school choices—the way parent resources, relationships, and strategies determine “who gets what, when, and how” (Laswell, 1936) in terms of schooling opportunities, and way these policies help structure disproportionate school access. By attending to families’ affordances of cultural, social, and political capital in studies of school choice, authorities may be more likely to design choice supports that address some demand-side inequities
How Communities of Practice Can Mitigate School Leader Burnout
No full textThis qualitative study expands our knowledge about school leader communities of practice (CoP) by examining the role they play in mitigating symptoms of burnout. Drawing primarily on in-depth interviews with school leaders in an urban California school district, this analysis applies Leiter and Maslach’s Structured Approach to Organizational Predictors of Job Burnout as a lens to understand school leaders’ experiences in a CoP focused on instructional leadership. Findings reveal dimensions of engagement known to reduce aspects of burnout, namely social closeness, a range of supports, and the perception of doing meaningful work that aligns with one’s values. This study extends the literature on school leader CoPs by drawing our attention to more subjective, humanistic benefits of CoP participation and it indicates how these cohorts may hold promise as structures for improving school leader sustainability
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
