Elsevier's Research Integrity and Publishing Ethics team, with guidance from an impartial field expert acting in the role of an independent Publishing Ethics Advisor, conducted an investigation and determined that the article should be retracted. Review of this submission was overseen, and the final decision was made, by the Receiving Editor Brian Lucey, despite his role as a co-author of the manuscript.

Credit Access for Small and Medium Firms: Survey Evidence for Ireland
Full text linkThe extension of credit to SMEs in Ireland has been identified as a necessary condition for economic recovery and job growth. The debate on whether the reduction in credit to this sector is caused by credit rationing by banks or a lack of credit demand on the part of SMEs has received much attention in media and policy circles. Owing to a lack of relevant available micro-data, research on this issue in Ireland has been sparse to date. The aim of this paper is to provide evidence using recently available firm-level data from the Central Statistics Office and the European Central Bank. Using the CSO data, we find a moderate decline in credit applications, coupled with a very large increase in credit rejection rates. Using firm-level production data, we find no evidence that the accepted firms have been pooled according to firm performance - more productive and fast-growing firms are as likely to be rejected as any other firm. Using the ECB data, we show that Irish firms are 15 to 18 percent more likely to be rejected for credit than a comparable Eurozone SME. We show also that Irish firms are less likely to have had decreased credit demand than other Eurozone SMEs in the 2009-10 period.
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
