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

Get PDFThe purpose of this course is to explain conceptual frameworks, theories, models, and research methods related to the analysis of leadership and leader behavior in educational administration. In pursuing this purpose, students will fulfill the following objectives: (a) gain an understanding of leadership research as a scholarly field, (b) develop a more sophisticated understanding of educational leadership, (c) explore some of the key leadership issues in American elementary, secondary, and postsecondary education, and (d) learn about some of the salient issues to consider in conceptualizing and conducting leadership research

Turbulence, perturbance, and educational change
Get PDFWhile scholarship on educational change has long accepted that disruptions to the status quo are an essential part of the change process, disruption has never been more central to planned change than it is in the current political context in the USA, where legislation has mandated school closure, reconstitution, and turnaround as required remedies for schools failing to produce annual student achievement gains required by government. We are also unfortunately hampered by the imprecise language that surrounds complexity- based theories of educational change. Words such as perturbance, turbulence, and disruption all have gained currency lately, but meanings are unclear and overlapping. This essay seeks to lend some clarity to the debate by defining turbulence as the perception of forces in an organizational environment with the potential to disrupt current modes of operation. This is distinguished from perturbance which is defined as the social process of actors coming together to adjust organizational practice to fit with the changing environmental context. The case is argued that sensible reformers ought to be fostering perturbance while minimizing the harmful consequences of excessive turbulence
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
