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
Domestic policy responses to the food price crisis: The case of Bolivia
No full textIn face of the global food crisis of 2007–2008, severe concerns arose about how developing countries would be affected by the extreme short-term fluctuations in international commodity prices. We examine the effects of the crisis on Bolivia, one of the poorest countries of the Americas. We focus on the effectiveness of the domestic policy interventions in preventing spillovers of the development of international food prices to domestic markets. Using a cointegration model, we study price interdependencies of wheat flour, sunflower oil and poultry. The analysis suggests that the policy measures taken had little effect on food security during the food crisis. Throughout the entire period, perfect price transmission between the Bolivian poultry and sunflower oil markets and the respective international reference markets existed. Bolivian prices were determined by international prices and the policy interventions in the markets of these two commodities were not found to have had an effect. The government’s large-scale wheat flour imports did not shield Bolivian consumers from the shocks of international prices
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
Quality Standards for Food Products - A Particular Burden for Small Producers in Developing Countries?
Get PDFThis paper develops an analytical framework which structures the problem of whether, how and to what extent small producers in developing countries are disadvantaged by the increasing prevalence of food quality standards. Based on a literature review, the empirical evidence is structured and research gaps are identified. The paper finds that small and medium producers rarely comply without support from downstream actors. In case of well-educated and relatively wealthy farmers, forward integration is also found. No empirical support exists for the intuitively appealing hypothesis of a lower cost of compliance per unit of output for large producers. Zusammenfassung In diesem Papier wird ein Analyserahmen entwickelt, um die Möglichkeit und das Ausmaß der Benachteiligung von Kleinlandwirten in Entwicklungsländern durch die zunehmende Verbreitung von Qualitätsstandards für Produkte der Agrar- und Ernährungsindustrie zu strukturieren. In einer Literaturübersicht werden die Ergebnisse empirischer Studien ausgewertet und Forschungslücken identifiziert. Es wird gezeigt, dass Kleinlandwirte aufwändige Prozessstandards selten ohne die Unterstützung von Unternehmen auf nachgelagerten Stufen der Wertschöpfungskette implementieren. Die einleuchtende und weit verbreitete Hypothese, dass die Cost of Compliance per Produkteinheit für große Produzenten niedriger als für kleine Produzenten seien, wurde bisher empirisch nicht bestätigt.Quality Standards, International Trade, EUREPGAP, Certification, Small Farmers, Developing Countries, Cost of Compliance, Agribusiness, International Relations/Trade,
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
