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
Vers une plus grande flexibilité du régime de change au Maroc : motivations et stratégie de transition
No full textEconomic history is marked by many events that revived the debate on the role of monetary policy and the exchange rate regime. The abandonment of national barriers, the interdependence of international financial markets, the repetition and contagion of financial crises, have led to a reconsideration of the choice of exchange rate regimes and the clarification of the arbitration they cover, Moreover, monetary authorities and economic policy makers have shown hesitation and distrust about the exchange rate regime to be adopted. The post Bretton-Woods era was marked by a rush for flexibility. Countries have now had the free choice to adopt the exchange rate regime best suited to their needs. Since then, this issue has not lost its timeliness and continues to be refreshed by new research perspectives. In Morocco, it is no longer a question of the choice between fixity or floating, but rather of the degree of fixity or flexibility to be retained, the current exchange rate regime is a fixed parity regime with the attachment of the dirham to a basket of currencies, mainly the euro (60%) and the dollar (40%), which has contributed to the establishment of a macroeconomic stability framework. It is in this perspective that the debate around Morocco’s transition to a floating exchange rate regime has resurfaced, the IMF says in this respect that. Together with structural reforms, this regime could help Morocco meet the challenges of competitiveness and likely contribute to boosting growth in the medium term.” Since 2013, Bank Al-Maghrib (BAM) has been working on the implementation of instruments (analysis and forecasting) enabling it to successfully transition to a more flexible exchange rate regime.

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

THE IMPACT OF POLITICAL STABILITY ON ECONOMIC PERFORMANCE IN AFRICA: EVIDENCE FROM 40 AFRICAN COUNTRIES
Get PDFLike all other human activities, the economy would not be properly exercised in a place where there is societal unsteadiness. Indeed, governments place the maintenance of political stability at the centre of their interests. So, what is the impact of maintaining this stability upon economic performance? To provide an answer to this question, we have studied this dynamic on the most unstable continent on the planet, Africa. This paper attempts to model the relationship between these two components under a dynamic type model, Autoregressive Delayed Model (ARDL), on a panel of forty African countries over a period of 20 years that goes from 1997 to 2017. The paper’s empirical results reveal that political stability has an impact on GDP per capita through investment. Moreover, the nature of this impact may depend on the location of an African country in the sample. Indeed, this model allows us to distinguish three categories of countries where the impact of stability on economic performance is either positive, negative or neutral. In the short run, political stability positively impacts GDP per capita across the Southern African region, while its impact is neutral for North African countries
