Chapter 5 Predictive Density Evaluation
No full textThis chapter discusses estimation, specification testing, and model selection of predictive density models. In particular, predictive density estimation is briefly discussed, and a variety of different specification and model evaluation tests due to various authors including Christoffersen and Diebold [Christoffersen, P., Diebold, F.X. (2000). "How relevant is volatility forecasting for financial risk management?". Review of Economics and Statistics 82, 12-22], Diebold, Gunther and Tay [Diebold, F.X., Gunther, T., Tay, A.S. (1998).

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
Le sfide del turismo glocale
No full textIl contributo si sofferma sulla crescente ‘glocalizzazione turistica’ che sta interessando il territorio bresciano per poi soffermarsi su alcune significative nuove sensibilità che si stanno diffondendo nel settore. Alla luce delle dinamiche in atto, si individuano alcuni driver emergenti che potranno caratterizzare, nell’immediato futuro, la ripartenza del turismo bresciano dopo il forte ridimensionamento dovuto alla drammatica emergenza sanitaria che ha colpito tale territorio nel periodo 2020-2021

Ambiente e territorio nella città di Brescia
No full textL'articolo intercetta in tutta evidenza la missione 2 del PNRR, che si riferisce alla rivoluzione verde e alla transizione ecologica. L'argomento è di particolare interesse perchè su questa missione si concentra quasi un terzo dei finanziamenti del Pnrr. I problemi relativi all'inquinamento delle acque e del suolo sfidano tuttora il territorio bresciano, nonostante sia già avviato un sistema articolato di interventi correttivi, tra i quali si segnalano l'incremento delle zone verdi e la riduzione del consumo di suolo. Il medesimo articolo interessa da vicino, nella sua parte finale, anche la missione 3, intitolata alle infrastrutture per una mobilità sostenibile
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
Brescia città della cultura

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
