Intellectual Capital disclosure in IPOs: is it worth it?
No full textWe study the association between Intellectual Capital (IC) disclosure and IPO results for a sample
of firms that have listed on the Italian stock market. By making use of an in-depth content analysis of the
non-financial information disclosed in the listing prospectus, we disentangle the effects of such a disclosure
on the underpricing from those effects that are produced on the price adjustment. Our empirical findings
suggest an overall positive effect of the IC disclosure on IPO results as the increase in the underpricing,
documented by previous literature as an opportunity cost, is preceded by an upward adjustment of the offer
price, which means that more money was raised. Moreover, we provide evidence that primary and secondary
market investors appreciate non-financial information in different ways. Our results encourage firms that
are going public to definitely engage in disclosure of IC as a means to improve IPO results
Diversità di genere nei Consigli di amministrazione delle Ipo italiane
No full textDall’analisi delle determinanti della gender diversity negli organi apicali di 83 Ipo dell’Mta in Borsa Italiana, emerge che la presenza femminile nei Cda risulta inferiore se le aziende hanno dimensioni maggiori, mostrano un azionariato più concentrato, una redditività aziendale migliore e presentano una anzianità più elevata, sia della società stessa, sia dei componenti il board. Anche l’appartenenza al settore finanziario si collega a una minore presenza femminile nel Cda. Di contro, la board gender diversity si intensifica grazie alla presenza di legami familiari delle consigliere con gli altri componenti del consiglio. In merito agli effetti prodotti dalla board gender diversity, pur confermandosi le criticità già emerse in letteratura, le Ipo con maggiore diversità di genere presentano performance di mercato più favorevoli, con una maggiore percentuale di sopravvivenza nel listino, una minore volatilità dei rendimenti e un rapporto migliore tra valore di mercato e valore di libro.
Our empirical analysis of gender diversity, within the boards of 83 Ipos listed in Italian Stock Exchange, shows a lower female participation in board of directors for companies of larger dimensions, higher concentrated shareholding structure, better profitability, higher seniority of both the company and of board members. Financial sector companies show a lower participation of women, as well. Conversely, board gender diversity intensifies when female members hold a familiar relationship with others board members. Our results on effects of gender diversity confirm the ambiguous outcomes revealed in existing literature. Nevertheless, we found evidence that Ipos with a superior gender diversity obtain improved market performances, with a longer survivorship on the stock exchange, lower return volatility and better book to market ratio
People have the power: post IPO effects of intellectual capital disclosure
No full textWe study the effects of disclosure practices regarding non-financial information in Initial Public Offering (IPO) prospectuses on the post IPO stock performance. Previous literature is in short supply of evidences regarding the effect of Intellectual Capital (IC) disclosure on the long-run IPO performance and it also provides inconsistent results, possibly due to the different IC classifications that are employed and to a variety of omitted concurrent factors which could befog the effect of the IC disclosure. In this paper, we disengage from any ready-made classification of IC and we shed light on the effects that unbiased IC information exert on the post IPO stock performance. In particular, we consider all the IC information that is provided in the listing prospectus of a sample of firms recently listed on Borsa Italiana by considering a series of 87 variables, as suggested by (Cordazzo J Intellect Cap 8(2):288-305, 2007) and we apply a principal component analysis to such information thus overcoming the subjectivity of any possible classification. The revealed IC components are then included in a multivariate analysis explaining the long-term IPO stock performance. We also include a wide set of variables to control for the short-term performance, the quality of the firm and other factors which could blur the effect of IC disclosure on the long run performance. Our empirical evidences show that information regarding the human resources and the information technology activities disclosed in the IPO prospectus continue to exert their positive effect on the behavior of secondary market investors in the 12 months that follow the IPO. Moreover, the information regarding the human resources is positively linked to the 36 months’ performance as well. Such a result underlines the key role that people have in the perception of a firm’s value in the IPOs setting, thus confirming that human resources are recognized as being very important contributors to the competitive advantage of corporations
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
