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
Trade liberalization and institutional reforms
Full text linkThe accession of Central and Eastern European (CEE) countries to the European Union (EU) is expected to lead to the new member countries becoming more like the older members, including in terms of trade. In this paper, we focus on two factors promoting CEE-EU trade integration: trade liberalization and institutional reforms. Measures of trade liberalization undertaken by both parties during the 1990s were very substantial, but did not always produce the expected upsurge of regional trade flows. Much less progress has been made in improving the functioning of CEE institutions (e.g., progress in the privatization process or in reducing corruption). Countries where most important changes at the institutional level occurred were also those that most increased their trade with the EU. Comparing the impact of these two factors, we find that improving institutions in CEE countries can generate as much trade as the removal of all tariff and non-tariff barriers. The paper also addresses the issue of the presence of reversed causality between trade and institutions, and the pro-trade effect of institutional similarity.

Essays on the impact of Brexit on the agricultural and food trade : an European perspective and focus on the French Brittany region and Ireland.
No full textLe Brexit est un cas de désintégration économique sans précédent qui soulève de nombreuses questions autour de ses potentielles futures conséquences économiques. Cette thèse a pour ambition d’identifier les défis post-Brexit auxquels seront confrontés les producteurs européens en matière de commercialisation des produits agricoles et alimentaires. Nous commençons par une revue de la littérature de l’intégration et la désintégration économique. Nous nous demandons comment sont traitées l’intégration et la désintégration dans la littérature, et si le Brexit représente le premier épisode d’une vague de désintégration en Union Européenne ou un cas isolé dans l’intégration croissante post-1945. À l’aide des modèles de gravité basique et structurelle, nous identifions les filières françaises les plus affectées, notamment la viande et les produits laitiers. Nous nous intéressons également à l’ensemble des pays européens, avec un focus sur la région Bretagne et l’Irlande.En plus de la viande, les fruits et légumes bretons sont les filières vulnérables identifiées. Les poissons et céréales irlandais sont sensibles à l’éventuel temps de transport additionnel post-Brexit via l’utilisation du “land-bridge”. Nous analysons différents scenarios sur l’aboutissement des négociations en matière de politique commerciale, non seulement entre le Royaume-Uni et l’Union Européenne, mais aussi entre le Royaume-Uni et les pays tiers. Enfin, cette thèse apporte une contribution originale à la littérature sur la construction des données commerciales domestiques, régionales, mais aussi des donnéesBrexit is a case of unprecedented economic disintegration raising numerous questions around the potential future economic consequences. This thesis aims to identify the post-Brexit challenges that European producers will face in terms of agricultural and food products trade. We start with a review of how economic integration and disintegration are analyzed in the literature, and question whether Brexit is the first episode in a new wave of disintegration in the European Union or an isolated case in the growing integration post-1945. Using basic and structural gravity models, we identify the French sectors that will be most affected, including meat and dairy products. We analyze all European countries, with a focus on Ireland and the French Brittany region. In addition to meat, Brittany’s fruit and vegetables are also identified as vulnerable sectors.Irish fish and cereals are sensitive to the potential post-Brexit increase in transport time via the “land-bridge”. We investigate different scenarios on the outcome of trade policy negotiations, not only between the United Kingdom and the European Union, but also between the United Kingdom and third countries. Both European Union countries and the United Kingdom will be less affected if Brexit is followed by the conclusion of a free trade agreement. Finally, this thesis makes an original contribution to the literature on the construction of domestic and regional trade data, but also of data related to modes of transport in international trade
