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
Unpacking Social Entrepreneurship: Exploring the Definition Chaos and Its Consequences in England
Get PDFSocial entrepreneurship has always been a contested concept, both within the academic discourse and in practice. A lot of scholarly effort has been put into analyzing the different definitions of social entrepreneurship and the negative consequences that the definitional debate has on the opportunity to advance social entrepreneurship as a research field. Very little is known about what the consequences of the multiple meanings of social entrepreneurship are for people working in the sector. This paper advances knowledge on this topic by looking at the social entrepreneurship sector in England and by investigating through qualitative research methods what sector members think about social entrepreneurship and its unclear boundaries. The results show that there are three different conceptions of social entrepreneurship within the sector in England. However, while everyone agrees on the presence of a definitional debate, opinions on what this means for the sector are several. Some members think it is something positive; some others think it is causing different issues, and a third group considers it as irrelevant
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
Brokerage as an institutional strategy in fragmented fields: the crafting of social entrepreneurship
Get PDFAlthough the scholarship on organizational fields has prevalently focused on emerging, mature and disrupted fields, some social arenas cannot be classified in any of these categories. One such field is that of social entrepreneurship. Despite its progressive establishment and the development of shared norms, understandings, regulations and values governing all of its players, this field still presents unclear boundaries, multiple conceptions, and a high ambiguity in terms of legitimate roles, practices and organizational forms. How can this be the case? The work of some scholars shows that meso-level factors are required to explain the peculiarity of this field. This study builds on their findings and uses the social entrepreneurship field in England as setting to explore how institutional agents can favour the creation of a fragmented field and successfully operate in it. Influencing a fragmented field requires both the creation and the maintenance of a coalition of key stakeholders supporting the enactment of the desired institutional architecture over time. Therefore, this research explores what organizations do to maintain the support of multiple stakeholders in competitive settings and to use the advantages that this creates for sustaining the co-existence of their desired field’s conception and institutional architecture with competing ones. Given the advantages that brokers have in such settings and in pursuing such a strategy, this work makes use of the well-developed literature on brokerage strategies, which focuses on tertius gaudens and tertius iungens strategic orientations, and connects it with that on institutional agency. By using as case studies four brokering agencies active in the social entrepreneurship field in England, this study discovers that combinations of gaudens and iungens strategic orientations, when used by institutional agents, can help them create and sustain over time their sub-field in face of competition. Furthermore, it explores how the co-existence of multiple organizations adopting complementary brokerage strategies as institutional ones, can lead to the creation of a permanently fragmented field. Together, these findings contribute to develop the literature on brokerage, on institutional agency — especially in relation to fragmented fields —, and that on social entrepreneurship
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
