Non-financial cooperatives through the lens of finance: why should they differ from non-cooperatives?
Get PDFFinance for non-financial cooperatives is a quite neglected topic in international literature. The modern financial theory, in fact, is tailored to large corporations: similarly with small business, studies try to identify what theoretical hypotheses are applicable and what not in financial decisions of cooperatives in light of their differences with respect to corporations, by theorising for exceptions and by adopting a residual approach. Empirical comparisons between financial decisions of cooperatives and those of corporations could be a fruitful approach to highlight the differences and to trigger the development of a wider extended financial theory. However, empirical findings are limited, mixed and not univocal, as emerge from the short review here provided, therefore not generalisable since referred to specific industries and countries. In this study, we try to theoretically rationalise if and why some specific features of cooperatives can affect their financial decisions in terms of performance measurement, capital structure choice and reasons and objectives of merging
Manipulation implicite d'une organisation multiagent via l'environnement
No full textLe modèle Agents et Artefacts enrichi avec les organisations propose un environnement de travail basé sur les artefacts pour mettre en oeuvre la coordination entre agents. La mise en place d?organisation dans un tel contexte nécessite cependant que les agents soient capables de raisonner et de manipuler explicitement des primitives organisationnelles (e.g. rôles, groupes, missions). An de diminuer cette contrainte, nous proposons de tisser des liens entre artefacts organisationnels et artefacts fonctionnels de l'environnement. De cette manière, les agents peuvent interagir implicitement avec l'organisation par le biais des artefacts fonctionnels. Dans ce papier, nous donnons une description formelle de cette proposition avec différents exemples illustrant l'intérêt de l?approche proposée
The Missing Link in the Monogermanide Series: YbGe
No full textHigh-pressure, high-temperature synthesis at 12 GPa between 750 and 1000 °C for 30 to 300 min yields the last missing rare-earth metal monogermanide, YbGe. Powder and single-crystal X-ray diffraction measurements reveal that the compound crystallizes in a FeB-type structure (space group Pnma, a=7.901(2) Å, b=3.8981(9) Å, and c=5.873(2) Å). The results of the chemical bonding study, while supporting the presence of polyanionic Ge chains interacting with the surrounding Yb through multi-atomic polar bonds, suggest a transitional scenario between the monogermanides formed by alkaline-earth elements and those formed by trivalent rare-earth metals
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
Integrating fusion techniques into the Collaborative Filtering search-based Recommender Systems
No full textDispelling 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
