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
The impact of ownership traits on acquisition behavior and performance
No full textContext This doctoral thesis delves into examining ownership traits and their impact on corporate acquisition behavior, with a primary emphasis on family-owned and private equity-owned firms. The research investigates the decision-making process of these block holders when investing in firms, particularly the dilemma they face in choosing between monitoring efforts to maximize shareholder value and pursuing private motives. The studies build on the determining factors that influence each type of owner's inclination towards value maximization, considering their unique identity, correlated private motives, and the relative significance of these motives compared to potential financial gains they might forego in pursuing private benefits. Aim To investigate how shareholder identity affects the acquisition behavior and performance of firms. Studies Chapter one explores how private family firms select their targets, focusing on diversification, internationalization, and innovation in their acquisition strategies. Using Behavioral Agency Theory, the study argues that these firms tend to prioritize social and emotional wealth (SEW) over purely financial gains. The paper hypothesizes that this tendency leads family firms to approach target selection cautiously, for instance, leading towards an aversion to acquiring highly innovative or cross-border targets. In chapter two, the focus shifts to the influence of private equity (PE) investors on publicly listed firms, particularly in the context of Mergers & Acquisitions (M&A). The chapter suggests that the motivation to create value through M&A decisions depends on whether the PE firm's investment occurs before or after the firm's initial public offering (IPO). Chapter three addresses the agency cost associated with surplus capital in the PE industry and its implications for buy-and-build strategies. As the industry accumulates an increasing pool of unallocated capital, PE firms face mounting pressure to deploy it judiciously. The study contends that implementing buy-and-build strategies, which involve making add-on acquisitions in portfolio companies, can effectively channel excessive levels of unutilized capital. Findings The first chapter underscores that family-owned firms prioritize SEW over financial gains in target selection for acquisitions, resulting in a conservative approach. This preference is particularly pronounced when led by family CEOs and founders. In the second chapter, the study reveals that post-IPO PE investors enhance M&A performance, especially with greater board representation. In contrast, pre-IPO investors are associated with lower returns, particularly when they exert stronger board influence and the firm's stock liquidity is lower. Finally, the third chapter addresses the pressure faced by PE firms to efficiently deploy surplus capital, introducing the buy-and-build strategy as a response. It finds that this pressure can lead to more investments in add-on acquisitions and a larger propensity for those deals to be unrelated to the platform's core industry. Moreover, buyout returns tend to be lower for buyout targets owned by pressured PE firms
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
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
