Cost Structure and Product Mix of Local Public Theatres
No full textThe purpose of this study is to analyse the cost structure of the Italian local public theatres in order to assess economies of scale and scope and the desirability of the reform of the subsidy system. A translog multiproduct cost function was estimated using panel data for a sample of 28 theatres over the period 1991-1993. The results indicate the existence of scale and scope economies for most output levels. In addition, the estimated marginal costs for the two outputs indicate that, ceteris paribus, an additional performance conducted inside or outside the theatre by the resident theatre group is generally more expensive than an additional performance conducted inside the theatre by external theatre groups. These results call for a reform of the public subsidy system which do not promote the proliferation, but the interchange and the diffusion of a limited number of high quality shows. © 1997 Kluwer Academic Publishers.The purpose of this study is to analyse the cost structure of the Italian local public theatres in

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
L'intervento Pubblico e l'Efficienza Possibile
No full textLe metodologie empiriche ed econometriche di analisi dell'offerta di servizi e beni d'interesse pubblico sono impiegabili per estrarre informazione sui processi valutativi delle performance di soggetti regolati e sulle modalità di organizzazione e di regolazione dei rispettivi settori. L'intervento pubblico, quindi, viene riletto relativamente agli obiettivi di massimizzazione dell'efficienza e dell'efficacia

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
