Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Does gender diversity on banks' boards matter? Evidence from public bailouts
We are the first to examine the impact of gender diversity on banks' boards on the probability and size of public bailouts. Our findings, based on a sample of listed European banks over the period 2005–2017, suggest that banks with more gender-diverse boards are less likely to receive a public bailout and receive a lower amount of bailout funds as a percentage of total assets than banks with less gender-diverse boards. Specifically, an increase by one standard deviation in gender diversity decreases the probability of a bailout by at least 2.44%, a significant reduction considering that the unconditional probability is 18.7%. Gender diversity is also positively related to bank performance, as proxied by ROA and Tobin's Q and with dividend payout ratios, consistent with the hypothesis that female directors are better monitors than male directors. These results are robust to a variety of econometric approaches and provide support for recent reforms in several EU countries regarding gender quotas

Pre-adoption market reaction to IFRS 9:a cross-country event-study
We are the first to examine the market reaction to 13 announcement dates related to IFRS 9 for over 5400 European listed firms. We find an overall positive reaction to the introduction of IFRS 9. The regulation is particularly beneficial to shareholders of firms in countries with weaker rule of law and a smaller divergence between local GAAP and IAS 39. Bootstrap simulations rule out the possibility that sampling error or data mining are driving our findings. Our main findings are also robust to confounding events and the extent of the media coverage for each event. These results suggest that investors perceive the new regulation as shareholder-wealth enhancing and support the view that stronger comparability across accounting standards of European firms is beneficial to international investors and outweighs the costs of poorer firm-specific information
Measuring disease activity in Crohn's disease
In the last few years the management of Crohn's disease (CD) has changed due to the introduction of new therapeutic agents that provide more alternative options in patients with severe diseases, introducing new concepts regarding treatment timing. At the moment, the absence of good predictors of disease outcome and a subclinical marker available to predict relapse during clinical remission are major problems in the management of CD. In recent decades, the evaluation of several variables has been proposed to address this issue, including disease behavior, clinical-endoscopic activity and intestinal damage. In particular, definition of mucosal restitution or healing after therapy has been proposed as a surrogate of efficacy and new goal of the therapy. Regarding this concept, several criticisms have been raised, such as the need to better define the role of mucosal healing in a transmural disease. In order to address this issue, new alternative techniques providing both extraluminal and luminal intestinal damage have been proposed, including ultrasonography, computed tomography and magnetic resonance imaging. © 2012 Springer Science+Business Media, LLC

Dispelling the Myths Behind First-author Citation Counts
We 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
