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
Raising the flag among the ruins: the crisis as helping hand for opposition parties?
No full textWithin the context of the economic downturn in southern Eurozone countries and the imposition of new constraints on national policy-making, this article examines the congruence between party issue prioritization, during and after the electoral phase. This is done through a longitudinal analysis of four countries (Greece, Italy, Portugal, and Spain) and use of party manifesto and parliamentary question data. We found that between the electoral and parliamentary arenas, parties tend to emphasize different issues. However, this occurs in different ways across time, countries, and parties. We propose a measurement of issue congruence in agenda framing between the pre- and post-electoral phases to assess to what extent elections provide a guide for public policies. Moreover, we propose arguments to explain different results in the analyzed countries and across parties. We show that the crisis magnified the capacity of the opposition to maintain programmatic coherence – a helping hand for opposition parties (including the radical ones) that succeeded in boosting the relevance of their signature issues
Introduction: Parties and voters in a multi-level electoral setting
No full textIn this article the main contents of this special issue are introduced. In particular, some of the main problems related to multi-level electoral competition in Italy are presented and how this work intends to analyse them. It will be shown that both parties and voters have strategically adapted and responded to the challenges of multi-level electoral competition to an extent that was probably unexpected in a
system undergoing transformation and whose inefficiencies are a conventional wisdom
The policy profile of populist parties in Europe: Policy purposeful with the competitive advantage of crises
Full text linkThis article moves beyond the pervasiveness of the concept of populism emphasising anti-elite sentiment to focus on the policy profile of populist parties. In doing so, it provides an understanding of how populism influences parties’ policy issue focus and what intermediates this relationship. Based on data from the Comparative Manifesto Project and the Chapel Hill Expert Survey, the article reveals the significance and facilitators of policy salience and issue ownership of populist parties. The main argument is that these parties hold policy profiles that they have coherently built over the years by representing policy issues mobilising citizens and aggregating voters. In this sense, they should not merely be seen as anti-establishment actors manoeuvring party systems strategically but also as ideologically driven and policy-purposeful parties. Moreover, populist parties have led efforts in emphasising the most urgent policy issues dictated by crises, making them central to party competition and to their policy profile
Improved bounds for composites and rigidity of gradient fields
No full textWe determine an improved lower bound for the conductivity of three-component composite materials. Our bound is strictly larger than the well-known Hashin Shtrikman bound outside the regime where the latter is known to be optimal. The main ingredient of our result is a new quantitative rigidity estimate for gradient fields in two dimensions
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
