Do shareholder coalitions affect agency costs? Evidence from Italian-listed companies
No full textThis study investigates the relationship between agency costs and ownership structure for a
sample of listed Italian companies to determine the impact of shareholder coalitions on agency
costs. Using a balanced panel dataset of 1956 firm-year observations for the period 2002–2013,
the results provide evidence that ownership concentration and debt play a limited role in
monitoring agency costs, whereas the type of shareholder plays an important role in either mitigating
or exacerbating agency costs. Family-controlled firms and coalitions among non-controlling
shareholders seem helpful in reducing agency costs. The results suggest that coalitions
among non-controlling shareholders both in family and non-family firms reduce agency costs.
The findings also indicate that multiple blockholders play a key role as mediators. The paper
provides a new perspective on assessing the role of agency costs in a bank-based, civil law
country. The results enable one to better understand the impact of blockholders on agency costs
and their interactions within family-controlled firms. The results also provide support for both
the entrenchment effect and the alignment-of-interests hypothesis
Female representation in the boardroom and firm debt: empirical evidence from Italy
No full textUsing a panel dataset of non-financial public companies in Italy covering the
period 2005–2013, this paper provides an empirical analysis of the relationship between
female representation on corporate boards and corporate debt. The presence of
women in the boardroom might seem to push significantly on debt leverage and
suggest a complementary role in the control and monitoring of agency costs. However,
consistent with Kanter’s (Am J Sociol 82(5), 965–990, 1977) critical mass theory, that
at a level of tokenism women take on a complementary role and at greater levels, their
role either becomes a substitute for debt level, or plays a weaker complementary role in
debt level and in the monitoring of agency costs. The presence of women board
members who are linked to the family firm appears to significantly decrease the degree
of debt leverage. Furthermore, the presence of greater female representation in the
boardroom decreases the agency costs to the firm
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
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
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
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
