Governance: Who Controls Matters
Full text linkIn this paper, we provide an outlook for further research on the topic of governance. We review four different approaches on the theory of the firm and discuss implications for governance, namely; nexus of contracts / agency theory, property rights / incomplete contracts, adaptation, and nexus of specific investments.governance, property rights, adaptation, nexus of contracts
La recherche, l'université et Free, acte II
No full textLa procédure initiée par Free concernant l'étude réalisée par Bruno Deffains a connu hier une étape importante. Rappelons que Free avait déposé une requête pour avoir accès à certaines données de l'ordinateur de Bruno Deffains. Par une décision du 15 novembre dernier, un huissier de justice a été désigné pour procéder à une recherche limitée. La «méthode Free» a profondément heurté et une pétition de soutien a été faite. La rétractation de l'ordonnance sur requête a été demandée et, par une o..
On the Difficulty to Design Arabic E-learning System in Statistics
Full text linkIn this paper, we present a case study, which describe the development of the Statistic e-learning-course in Arabic language –``Arabic MM*STAT´´. The basic frame forthis E-book, the system MM*STAT was developed at the School for Business and Economics of Humboldt-Universität zu Berlin. Arabic MM*STAT uses a HTML - based filing card structure. We discuss the difficulties of the implementation of such a system in to the standard WWW formats and present the solutions needed for Arab educational institutions and the Arabic user. Those solutions are consistent with the Arabic language, and include the modern trend in the e-learning environment.electronic books, Arabtex, MM*STAT, Statistical software
Labor Conflicts and Inefficiency of Relationship-Specific Investments: What is the Judge's Role?
Full text linkThis paper presents a model of litigation in the context of a labor contract. The main objective of our analysis is to determine whether and under which conditions it is efficient that the judiciary arbiters a labor conflict and how the judge's decision should be made in order to be optimal. We embed this idea by considering a relationship between an employer and his worker, in which they can make (non contractible) relationship-specific investments. The optimality here refers to the best investment incentives of the parties allowing to maximize the generated surplus. We derive conclusions about the judge's behavior giving right investment incentives and determine how the division of the surplus should vary depending on several economic and social parameters.Labor Law, Litigation, Investment Incentives, Bargaining.
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
Technological Choice under Organizational Diseconomies of Scale
Full text linkWith adverse selection, diseconomies of scale associated with hierarchies may induce the implementation of a second-best technology. This occurs whenever rents to lower tiers of the hierarchy increase faster than total surplus. This is more likely with longer hierarchies.Adverse Selection, Hierarchies, Technology
