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
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
OPPORTUNITY COST ARE A KEY TO CASH PUZZLE OF THE COMPANY
No full textFeatures of influence of opportunity cost on the cash policy of the Russian companies are considered. The author analyzes relationship of cause and effect of escalating of cash. The author researched features of a choice the Russian companies of sources of financing. The author shows that availability of opportunity costs forces the companies to be reoriented on internal sources of financing. Opportunity costs are the indicator for a choice of optimum financing. The model (specification) presented in work is tested for determination of its adequacy, from the point of view of quality of forecasting. It is estimated three kinds of specifications: pooled regression, regression with a random effect and regression with the fixed effect. The purpose of work attempt to open cash puzzle of company disclosing of a puzzle. That is, to reduce opportunity costs for preserving of cash as the preventive motive, allowing to struggle with financial restrictions. Novelty of the presented work consists that the companies can rationally manage cash holdings, using negative shocks (signals) in the capital market, to expect them and without supposing the situations connected with financial restrictions

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
Role of the Shareholder in Construction of an Institutional Order in the Company
No full textSetting up an institutional body will allow to balance interests between interested participants in the company (first of all between management and shareholders).

Features governance of the company from board of directors
No full textThis paper considers the features of corporate management on the part of board of directors. This paper includes consideration of efficiency of decision-making, the resolution of conflicts be-tween shareholders, realizations of investment in the company. In the presented work are considered mutual relations between board of directors and shareholders, from the point of view of accepting of effective decisions. The author analyzes one of tools of motivation for board of directors, namely stock options as incentives for company executives which effective decisions help to make. Realiza-tion of stock options in the Russian legal realities at times is an inconvenient task. Besides, principal causes of infringement are considered from controlling shareholder: imperfection of the national corporate legislation, an inefficiency of governance from board of directors. The author notices that the company management is capable using the management powers, effectively to manage the com-pany, in due time to inform shareholders on forthcoming strategic business decisions. Thereby, al-lowing diligent to expect shareholders injurious moods from, first of all, majority shareholders and to permit corporate conflicts. The permission agency problem is reached by means of optimization of structure of the capital of the company. Thereby, the permission of an agency problem (at least its mitigation), will allow board of directors to make more effective decisions and also to promote in-vestment realization in the company. Eventually investors build the policy with the company on fi-duciary bases, giving a priority of that which copes strong management
