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
THE GENERAL FRAMEWORK OF COMPETENCIES IN THE CONTEXT OF VIRTUAL ORGANIZATIONS
Get PDFIt is widely accepted that one of the virtual organizations great advantages, is that the participating firms can join in larger and more complex projects in a more flexible and swift fashion than would be the case for an individual. The shaping of the VO’s architecture in order to be able to react quickly to market demands as well as the immediate coordination of a number of partners requires not only flexibility but also predefined rules and roles. This is why I consider there is need of an analysis regarding the possibility of creating a general framework of competences. The result of this research includes a number of elements and processes that have influence on the general framework of competencies and proposes a topic for future evaluations.virtual organization, competence management, contextual complexity, complexity of task.
New Method for Modeling and Operating of the Virtual Enterprises
Get PDFMuch research has been conducted to define what a virtual enterprise (VE) actually is and how it should work. This paper addresses the more specific question, how a virtual enterprise can be designed to be agile and to so best support short-term business opportunities. The cases on virtual enterprises studied in this research suggest that in order to adequately respond to a temporary window of opportunity in the market, engineering and implementation competencies cannot be created for the occasion but need to be preinstalled and on standby. Thus, each research study conducted in this sense has tried to ascertain a set of methods and tools to select partners, reengineer business and logistic processes and to set up an information and communication platform for the virtual enterprise
THE COLLABORATION EFFECTIVENESS AND EFFICIENCY IN A VIRTUAL ENTERPRISE
Get PDFAn important number of factors are creating different types of barriers among the members of a virtual enterprise affecting the collaboration between them. In our attempt to study the evolution of importance of these factors we have chose a set of three studies published in the last decade and a half, which we consider as relevant. This study aims to identify new research directions for mitigating the effects of collaboration barriers by highlighting the most important factors and how they affect the effectiveness or efficiency of collaboration.virtual enterprise, collaboration, effectiveness, efficiency.

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
