The Emergence of the Global Student Forum and Prospects for Increased Student Participation within the International Education Polity
Full text linkWith the collapse of the two competing international student organizations, the International Union of Students (IUS) and the International Student Conference (ISC), in the second half of the twentieth century, students were left without a representative voice on the global stage for decades (Gronne, 2017). This vacuum in global student representation coincided with a period of increased globalization in higher education, defined by Altbach as a “broad economic, technological, and scientific trends that directly affect higher education” and the effects of which are “beyond the control of any one actor or set of actors” (Altbach et al., 2009, p. 23). Today, the system of global higher education policy-making is increasingly non-hierarchical, involving negotiation and mediation from a range of stakeholders, as opposed to unilateral decisions by single authority (Klemenčič, 2012). Key players in global higher education polity include intergovernmental organizations that hold regular education policy-making fora and processes between Member States, such as the United Nations and its subsidiary agencies, international financing institutions and multilateral funds focused on education, and a diverse, vibrant global education civil society sector composed of non-governmental organizations and trade unions who are often formally recognized and represented in the former two entities.
The Global Student Forum entered the global higher education polity in 2020. This chapter analyzes the emergence of the GSF and how, and to what extent, a democratic, representative, global student entity can influence the decentralized higher education policy-making framework and processes at the global level. To do so, the existing systems of representation and the nature of student intermediation in key global education stakeholders are assessed. This analysis utilizes the framework proposed by Klemenčič and Palomares (Klemenčič and Palomares, 2018) and the understanding that formalized routes of engagement strengthen the “legitimate power” of student organizing and enables a “higher propensity for students to influence policy processes” (Klemenčič, 2014, p. 402). Drawing on a wider range of documents issued by relevant student unions and international education sector organizations and harnessing the findings of a series of expert interviews conducted throughout 2021 and 2022, this chapter starts with the description
84of the process that led to the foundation of the Global Student Forum. The following section offers an analysis of GSF internal structures, classified in line to the already existing literature on student unions. The global decision-making environment on educational policy and students’ role in it are then introduced, leading to a threefold analysis of intergovernmental organizations, education financing institutions, and international organized civil society
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
