L’accessibilità multimodale nelle aree costiere: strategie per le destinazioni turistiche sostenibili
No full textUn sistema efficiente di mobilità multimodale costituisce un fattore importante per migliorare l'accessibilità dei territori e, in particolare, delle destinazioni turistiche in chiave sostenibile. Il problema è particolarmente rilevante nelle zone costiere che tradizionalmente vedono nell'auto privata il principale mezzo di trasporto utilizzato a causa delle lunghe distanze di viaggio dai principali hub di accesso alla regione, della minore densità di popolazione locale che non giustifica un’elevata frequenza dei servizi di trasporto pubblico e della elevata stagionalità turistica che aumenta le diseconomie legate al dimensionamento efficiente delle infrastrutture disponibili. In questo lavoro si forniscono i principali risultati di un’estesa ricerca condotta nella regione Puglia per valutare il grado di accessibilità delle città costiere, confrontando i tempi di percorrenza del sistema di trasporto pubblico rispetto all’opzione del mezzo privato, necessari per raggiungere tutte le 67 destinazioni costiere pugliesi dalle principali porte di accesso regionali (aeroporti, stazioni ferroviarie, porti). Applicando per la prima volta su scala regionale/locale la metodologia sviluppata a livello nazionale dall’ex Ministero delle Infrastrutture e dei Trasporti (MIT, 2018), lo studio fornisce diversi suggerimenti sulla politica dei trasporti e sulle strategie operative utili per conciliare lo sviluppo di attività turistiche competitive con l'accessibilità urbana sostenibile
Museums’ Economic Performance and Directors’ Recruitment Process: An Assessment of the Recent Policy Reform of the Italian Museum Sector
No full textWe study the economic effects of a reform of the national museum sector, the so-called Franceschini Reform, implemented in 2015. The reform introduced a new organization of the national museum system. One of the most innovative instruments of the policy was the establishment of a different method - an international call for applications - in the selection of directors of major museums (museums of “national interest”). The article studies the effects of this new recruitment policy on museum economic performance, focusing on revenues. Using a difference-in-difference technique for the years 2014 to 2017, we show that the new recruitment policy improved the revenues of treated museums throughout Italy by a range between 17% and 26%. We also find that the characteristics of the directors (age, field of degree, and study abroad experience) play a role in explaining the increase in revenue of these Institutions. We thus find evidence of significant benefits of the policy. The new knowledge may be useful for improving museum and
cultural sector management policies
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
Transport endowment, knowledge spillovers and firm performance in emerging economies
Full text linkThis work explores the link between firm performance in emerging economies and transport infrastructure endowment, as a key element of the entrepreneurial ecosystem. We ground on the idea that transport infrastructures, by enabling connectivity, interactions and the exchange of knowledge and ideas, have the potential to enhance commercial opportunity recognition, technological development and, thus, firm economic performance. We also emphasize the crucial role of logistics system performance in providing better linkages between suppliers, firms and customers. The empirical analysis is focused on emerging economies whose infrastructure endowment is lower than those of developed ones; thus, its improvement is likely to be associated with better performance of their firms and economies. The results suggest that part of country-level differences in firm’s labour productivity is explained by transport endowment. Particularly, transport networks, such as roads and railways, and the logistics system and services show strong and positive relationships with productivity, while transport nodes, such as airports and ports, show little or no association. This might occur because networks spread knowledge spillovers in a more capillary way compared to nodes. Overall, the empirical results suggest that policy-makers in emerging economies can sustain the economic performance of firms, with beneficial effects on the economic system, by improving their transport endowment
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
