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
Nested Causality of American Depositary Receipts and Underlying Original Shares
No full text本研究主要目的在於實證台灣六支在美國上市的美國存託憑證，包括台積電、聯電、友達、旺宏、矽品以及日月光，其標的股票與存託憑證之動態關係。根據Granger(1969)提出的定義，兩變數間的因果關係可分為獨立、同時影響、單向關係以及回饋關係。Chen & Lee (1990)進一步以多重假設檢定方式來檢驗網狀因果關係，以求更精確判定兩變數的動態關係。
本研究發現，台積電、聯電、友達、日月光等四家公司在紐約證交所發行的美國存託憑證與其標的股票呈現回饋影響關係，而旺宏及矽品在那斯達克上市的存託憑證與其標的股票呈現單向影響關係，有存託憑證價格領先台灣股票價格之趨勢。且由模型觀察，過去的存託憑證報酬與台灣標的股票當其報酬呈現正相關，因此推斷可藉由觀察過去的存託憑證走勢來操作台股獲利。The main objective of this study is to examine the relation between ADRs and Taiwanese stocks is independency, contemporaneous relation, unidirectional relation, or feedback relation, which is defined by Granger (1969). Chen and Lee (1990) provided nested causality tests which apply multiple hypotheses testing procedure to identify the nature of the relationship between two financial series.
There are three findings in our study. First, the final result of nested causality tests, feedback relations exist in Taiwan Semiconductor Manufacturing Co., United Microelectronics Corporation, AU Optronics Corporation, and Advanced Semiconductor Engineering Inc as well as unidirectional relations from ADRs to original shares in Macronix International Company Limited and Siliconware Precision Ind., Co. Ltd. as a result of different infrastructure in the NYSE and Nasdaq stock market. Second, in the cases of Macronix International Company Limited, and Siliconware Precision Ind., Co. Ltd. shows a unidirectional relation from ADRs to Taiwanese stocks. It’s plausible that different level of legal restriction, corporate governance, and requirement of foreign exchange, force companies engaged in cross-border listing to keep information transparency. The last is that past return of ADRs, are always significantly positive related to current return of Taiwanese stocks, then we can take this as a investment guide for buying Taiwanese stock by watching past performance of ADRs.CONTENTS

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
