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
Essai econometrique sur le lien de causalite entre le capital humain et la croissance economique : cas du maroc
No full textRésumé
L'objectif de ce papier est de cerner la relation entre l’éducation et la croissance économique dans le cas du Maroc. Il soutient que le rendement faible de l'éducation au Maroc, que ce soit d'un point de vue de quantité (retard dans la généralisation d'accès au système) que d'un point de vue de qualité (inadéquation entre les formations et les besoins de l'économie nationale en main d'œuvre.etc.) est un des facteurs fondamentaux pour l'explication des niveaux faibles de croissance économique du pays.
Une estimation économétrique sur des données marocaines, a été effectuée sur la période 1971-2017 pour valider empiriquement la relation entre l'éducation et la croissance. Les techniques économétriques d'étude de la stationnarité, de VAR, de causalité et de cointégration ont été utilisées pour identifier l'existence et le sens de la relation. Les résultats obtenus tendent à confirmer l'inexistence d'une relation positive entre l'éducation (approximée par les taux de scolarisation dans les trois niveaux primaire, secondaire et supérieur) et la croissance économique au Maroc.

Abstract
The objective of this paper is to identify the relationship between education and economic growth in the case of Morocco. It argues that the low performance of education in Morocco, both from a quantitative point of view (delay in the generalization of access to the system) and from a quality point of view (mismatch between training and the needs of the national economy in terms of manpower, etc.) is one of the fundamental factors in the explanation of the low levels of economic growth of the country.
An econometric estimation on Moroccan data, was carried out over the period 1971-2017 to empirically validate the relationship between education and growth. The econometric techniques of stationarity study, VAR, causality and cointegration were used to identify the existence and direction of the relationship. The results obtained tend to confirm the non-existence of a positive relationship between education (proxied by enrollment rates in the three levels of primary, secondary and higher education) and economic growth in Morocco.

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
Covid-19 au Maroc: comment penser la relance économique ?
Get PDFEn contexte de crise sanitaire du Covid-19, le Maroc a instauré une série de mesures préventives dans sa lutte contre la propagation de la maladie dans l’objectif d’éviter la saturation du système de santé. Parallèlement, un nombre de dispositifs ont été mis en place pour soutenir l’économie nationale en période d’arrêt des activités. C’est donc dans le contexte d’une récession économique mondiale imminente que nous conduisons notre réflexion sur les perspectives futures pour sortir de la crise avec le moindre dégât possible, et ce, en mettant l’accent sur l’importance des deux politiques, monétaire et budgétaire, qui représentent, traditionnellement, les deux leviers de la relance économique. In the context of the Covid-19 health crisis, Morocco has implemented a series of preventive measures in its fight against the spread of the disease with the aim of avoiding saturation of the health system. At the same time, a number of measures have been put in place to support the national economy during periods of shutdown. It is therefore in the context of an imminent global economic recession that we are conducting our reflection on the future prospects for exiting the crisis with the least possible damage, and this, by emphasizing the importance of the two policies, monetary and budgetary, which traditionally represent the two levers of economic recovery.في سياق الأزمة الصحية لفيروس كوفيد -19 ، أدخل المغرب سلسلة من الإجراءات الوقائية في مكافحته لانتشار المرض بهدف تجنب الازدحام في النظام الصحي. وفي الوقت نفسه ، تم اتخاذ عدد من الإجراءات لدعم الاقتصاد الوطني في فترة الانكماش. لذلك ، في سياق الركود الاقتصادي العالمي الوشيك ، فإننا نفكر في الآفاق المستقبلية للخروج من الأزمة بأقل قدر ممكن من الضرر ، وذلك من خلال التأكيد على أهمية السياستين ، النقدية والمتعلقة بالميزانية ، والتي تمثل تقليديًا أداتين أساسيتين للانتعاش الاقتصاد
Le contrôle financier de l’Etat sur les établissements et les entreprises publics (EEP) entre les impératifs de la loi et les déterminants pratiques pour une analyse de la performance
Get PDFDans ce travail de recherche, nous essayerons de traiter l’action de l’Etat (contrôle financier) vis-à-vis de son portefeuille public (établissements et entreprises publics) à travers l’angle manageriel. Dans un premier point, nous démontrerons le soubassement théorique et juridique du contrôle financier de l’Etat. En deuxième point, nous focalisons l’attention sur l’aspect pratique du contrôle financier à travers sa structure et ses outils pratiques. En dernier point nous ferons une lecture analytique du concept de performance publique comme une finalité pour le contrôle financier. L’objectif étant d’analyser les pratiques managériales utilisées par les EEP et dégager des enseignements qui pourraient être exploités par les responsables dans l’instauration des meilleures pratiques managériales
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
