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
Public Interest Shareholder Engagement
No full text© 2025 Samantha Si Min TangWhile debates about corporate engagement with public interest issues have flourished, how various shareholders use corporate law rules to engage companies on public interest issues remain poorly understood. By comparing case studies from Australia and Singapore, this thesis proposes two models of public interest shareholder engagement based on shareholder attributes
Foreign Institutional Holdings and Value Relevance in Stock Valuation
No full text本研究主要討論三個主題：台灣上市公司﹝金融業除外﹞自1994至2007年價值攸關性之變化、外資法人持股比例與股票評價攸關性，以及外資法人在被投資者中所扮演的角色。本研究利用「盈餘—帳面值—股價」的關聯模型，以及盈餘投資組合法檢驗攸關性之變化，發現台灣盈餘與權益帳面值的股價評價攸關性，在2005至2007年有明顯的提升，此外，攸關性之走勢在2001年以後也明顯較2001年以前平穩。此現象與台灣自2001年解除外資持股上限、2002年加入世界貿易組織WTO以及近十年來之會計變革或有相關。研究著眼外資法人持股比重越來越高，以及持股比例係一量化指標，採用Dhaliwal et al. (2005) 之方法，將外資法人持股比例加入市場評價模型，探討此因素是否會影響每股盈餘、每股帳面價值在股價評價攸關性之權重，實證結果顯示外資持股比重越高的公司，盈餘在有利潤之公司的股價評價權重越高，權益帳面值則是在有損失公司之評價權重越高。此外，本研究分別以資產報酬率、股東權益報酬率、負債比率控制財務健全度以後，外資法人持股比例對於正、負盈餘公司的盈餘、權益帳面值的評價權重仍有顯著且相同方向之影響，顯示市場認為外資機構投資人除了在持股選擇上扮演受託人與善盡忠實義務之角色以外，同時也在被投資公司之中扮演長期治理監督的角色。Following Taiwan’s deregulation of foreign investor’s stock holdings limits in 2001, the increase in the level of foreign institutional investment has posed great opportunity for Taiwan accounting academia to study investment behaviors, holding preferences of this new set of trader and its impact on Taiwan stock market. This study aims to study three topics: first, trend of value relevance in Taiwan from 1994 to 2007; second, the relationship between foreign institutional holdings and the extent investors utilize accounting numbers in stock valuation; and third, the roles foreign institutional investors play in their investees. y market valuation regression models, this study empirically shows that trend of value relevance becomes steadier and higher after 2001; furthermore, higher level of foreign institutional holdings can elevate investors’ reliance on earnings (equity book values) when valuing profit (loss) firms. In addition, this study also suggests that foreign institutional investors not only play fiduciary roles who self select into more financial healthy firm in the very first place; on the other hand, they also play governance roles that have implication of a firm’s long-term profitability. However, in what way and to what extent foreign institutional investors dynamically affect their investees’ operation prospects worth further investigation.Table of Contents Introduction 1 Literature Review 6 Research Topics 12.1 Trend of value relevance 12.2 Relationship between foreign institutional ownership and value relevance 15.3 The roles foreign investors play in their investees 22 Models and Variable Measurement 25.1 Sample selection 25.2 Models and Variables 26.2.1 Trend of value relevance 26.2.2 Level of foreign institutional ownership and value relevance 32.2.3 The roles foreign investors play in their investees 34.

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
