Sitting on the Board or Sitting on the Throne? Evidence of Boards{'} Overconfidence from the Italian Market
No full textBetween things we know with certainty and things we do not know absolutely there is a continuum spectrum of things we know something about: but how much do we know? People think they know more than they actually do: this tendency is defined as overconfidence. We explore the phenomenon with respect to mergers and acquisitions (M&As) and we introduce a new proxy for overconfidence: interlocking directorship (ID). We review different factors at the origin of this decision making (DM) bias and we theoretically justify why directors may be affected by it. Using event-study methodology, an empirical analysis is conducted on a multi-sector sample of Italian listed companies, which includes 296 M&A deals realized over the period 2000–2013. We analyse the impact of these extraordinary operations using cumulative abnormal returns (CARs) adding in the model control variables and measures of overconfidence. Results show negative and statistically significant average CARs around the date of announcement of the operations, suggesting that M&As are value destructive in the short term, and sitting on more than one board even increases this result, corroborating the hypothesis of managerial overconfident evaluations
Do Really Accrual Numbers Affect the Financial Market? An Empirical Analysis of ESA Accounts Across EU
No full textThe adoption of a full accrual framework in the public sector is differentiated country by country
both for budgeting and for reporting phases. The purpose of this article is to address the
following broader research question: How do accrual numbers affect the financial markets?
The 10-year average interest rate on sovereign bonds across the European Union is used as a
dependent variable. The results of the research show an unclear relation among the variables
investigated. Given this evidence, an alignment between micro- and macroaccounting rules
could be pursued. We argue the suitability of the Australian experience in this sense
Interlocking Directorship across Italian listed companies: Evidence from a natural experiment
No full textThe financial crisis of 2008 and the introduction of the Interlocking Ban in 2011 (for financial firms) deeply influenced the Italian corporate governance system. The aim of the present study is to investigate to what extent personal ties among the directors of Italian listed companies have changed after these two events. We describe the evolution and dimension of the phenomenon of interlocking directorship (ID) for all the Italian listed companies over the period 1998–2013 using different methodologies. Social network analysis discloses the existence of clusters of companies whose links remain dense after the crisis, while connections to the peripheral units of the system decrease, reducing the overall connectedness. Results reveal that, over the period, there is a reduction in the cumulation ratio which still remains high and mainly due to a high number of directorships for multiple directors. This reduction is more severe after 2008 when both the financial crisis and the Interlocking Ban occur. In disentangling the two effects we observe ID reduction during and after the crisis, also for non-financial firms, confirming the general tendency of a decline in national board interlocking networks
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
