LES FACTEURS EXPLICATIFS DE LA VARIATION DU PRICE EARNING RATIO DES PETITES ET MOYENNES ENTREPRISES
Get PDFLe Price Earning Ratio est un indicateur qui renseigne les investisseurs et les analystes sur la cherté d’un titre et lui confère de ce fait un attrait préférentiel sur le marché. Ses variations affectent significativement la perception du titre et plusieurs facteurs en sont responsable. Notre objectif dans cette étude est de déterminer les facteurs explicatifs de la variation du PER dans les PME au Cameroun. Quoiqu’en contexte hors bourse, les PME semblent intéressées par les opérations d’ouverture du capital. C’est alors qu’un échantillon de 166 entreprises a été extrait d’un panel de données de 2013 à 2015 collectées par l’Institut National de Statistiques du Cameroun. La régression linéaire multiple sont les outils mobilisés pour atteindre notre objectif. Les résultats montrent que la rentabilité financière, le taux de croissance des bénéfices, le ratio d’endettement global ainsi que la taille ont une incidence positive et significative sur la variation du PER. Une étude confirmatoire a été menée en parallèle au moyen d’un questionnaire administré à cinquante (50) entreprises de la même base. À l’aide des moindres carrés partiels, il ressort de celle-ci que les facteurs de performances sont les principaux déterminants de la variation du PER. Face à ce constat, les managers de PME disposent désormais de puissants leviers d’attraction des capitaux
Spécificité des actifs et choix d'un mode de financement des enteprises manufacturières
Get PDFObjectif : Cet article a pour objectif d’analyser les effets de la détention des actifs spécifiques sur le choix des modes de financement des entreprises manufacturières Camerounaises.
Méthode : Une étude exploratoire a permis de caractériser les actifs spécifiques des entités prospectées. La vérification des hypothèses émises a nécessité une enquête par questionnaire auprès d’entreprises industrielles. Les données collectées ont fait l’objet d’analyses de régressions linéaires multiples.
Résultats : Les résultats montrent que la réputation a un impact positif et significatif sur l’augmentation du capital. Par contre, le capital humain et la recherche et développement impactent négativement le financement par endettement ; contrairement à la sous-traitance.
Originalité/Pertinence : Le papier a l'originalité de traiter de la spécificité des actifs en contexte PME. Il met en exergue la réalité selon laquelle la spécificité de l'actif peut influer sur les sources de financement
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
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
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
