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
I criteri di valutazione finanziaria del Project
No full textIl Project Financing è un metodo di organizzazione e ricerca di capitali per la realizzazione di opere ad alta intensità di capitale, indipendenti e complesse, la cui fattibilità è legata alla capacità del progetto di generare flussi di cassa soddisfacenti sia per gli azionisti che per i finanziatori. L'obiettivo del presente lavoro è quello di esaminare l'aspetto valutativo del Project Financing. Dopo una sintetica descrizione teorica dell'analisi economia e della sostenibilità finanziaria, si discute l'analisi di sensibilità a cui è sottoposto il progetto di investimento prima di pervenire ad un fondato giudizio sull'accettazione. La parte finale dello studio è dedicata alla simulazione di un intervento riguardante la realizzazione di un Centro benessere
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
The Long-Run Performance of IPOs in Italy: A Comparison of Venture and Non-Venture-Backed Companies
No full textThe phenomena associated with the performance of newly listed companies has increased the interest of many
researchers who have developed a vast literature on long-term underpricing and underperformance, which together
with hot and cold issue markets, represent the three anomalies that have always accompanied with Initial Public
Offerings (IPOs). The objective of this work is to investigate the long-run performance of IPOs of venture and
non-venture-backed companies. The analysis of a sample of 102 IPOs carried out in Italy in 1998-2005 revealed
that both companies (venture-backed and non-venture-backed) showed negative values, thus, confirming the
phenomenon of underperformance. During the 36 months following their listing, venture-backed companies
seemed to register negative and statistically significant values both with the CARsVB methodology (-93.99%) and
the Buy and Hold Abnormal Returns methodology (BHARsVB -88.37%). Venture-backed companies, unlike nonventure-
backed companies, seem to be able to restrain the losses, measured by both methods, in the first 12 months
(CARsVB -12.38% -20.15% CARsNVB; BHARsVB -10.17%; BHARsNVB -15.51%). During the 36 months, however,
the IPOs showed negative and statistically significant values regardless of whether they were venture or
non-venture-backed. The test on the difference between the average abnormal returns of the two methodologies
(CAARS and BHAARs) did not produce statistically significant results. The Wealth Relative was calculated and
from the results it would appear that the portfolio of venture-backed IPOs does not register “brilliant” performances.
The portfolio of 102 IPOs does not seem to beat the “market portfolio”. In conclusion, therefore, the phenomenon
of underperformance seems to be real in our country and is documented by strongly negative and statistically
significant values obtained from the samples of IPOs analyzed
CORPORATE GOVERNANCE, RISK-TAKING, AND FIRM PERFORMANCE: EVIDENCE FROM ITALY
No full textUsing a balanced panel data of 82 Italian listed companies the relationship
between corporate governance, risk-taking, and risk-adjusted performance
has been investigated during the period 2002-2013, which includes both the
pre-crisis time horizon and the one during the crisis. The results achieved
provide evidence of a negative and statistically significant relationship between
risk-taking and ownership concentration; conversely, there is a positive
and statistically significant relationship between ownership concentration,
risk-adjusted performance and Tobin’s Q. However, instead of a definite linear
relationship between risk-taking, risk-adjusted performance and ownership
structure, a non-monotonic relationship seems to emerge. The presence
of independent directors in the board has a positive (negative) impact on firm
performance (risk-taking), while a wider board is positively associated with
both risk and the value of the firm
Religiosità e corporate financial decisions
No full textLa religione viene da più parti considerata una proxy culturale, un valore, una norma sociale, una istituzione informale che racchiude credenze che a loro volta influenzano le attitudini e i comportamenti degli individui e delle imprese. Le credenze religiose, più in generale, assumono il ruolo di modelli di ordine sociale che influenzano il comportamento economico della società, modellano i sistemi legali, e producono un impatto sui governi che promuovono diversi tipi di mercati e istituzioni finanziarie. La religione è parte integrante del capitale sociale, ossia «l’insieme di relazioni di fiducia, di affidabilità, di rispetto delle regole, indispensabili ad ogni convivenza civile» (Caritas in Veritate). Dall’analisi testuale delle Encicliche e degli altri scritti papali si evince il forte richiamo alla funzione sociale dell’impresa e alle sue finalità produttive, etiche, e non speculative: i governanti delle imprese devono operare nell’interesse di tutti i stakeholders in base al princìpio secondo cui il «denaro deve servire ma non governare». Il presente lavoro si inserisce nel filone di studi che esamina il rapporto tra il pensiero della Dottrina Sociale della Chiesa e il corporate financial decisions. Lo studio in parola, oltre a fornire una cornice teorica sul nesso tra religione, economia e finanza, espone i principali risultati dell’evidenza empirica sulla relazione tra religiosità, corporate governance, e corporate financial decisions
Strutture proprietarie e benefici privati di controllo
No full textLe strutture proprietarie e i benefici privati di controllo occupano uno spazio di rilievo nell'ambito della finanza aziendale. La presenza di strutture proprietarie fortemente concentrate come nel caso dell'Italia, in cui la separazione tra proprietà e controllo avviene tramite i gruppi piramidali e mediante l'emissione di azioni senza diritto di voto, genera conflitti tra gli azionisti di maggioranza e quelli di minoranza. L'esercizio del controllo permette ai detentori di usufruire in larga misura dei benefici privati e ciò comporta l'attuazione di operazioni non guidate dalla logica sottostante alla teoria di creazione del valore per tutta l'impresa bensì effettuate esclusivamente a proprio vantaggio. Il lavoro, oltre a esporre un quadro teorico sulle strutture proprietarie e sui benefici provati di controllo, fornisce i risultati di alcune verifiche empirich
