Energy transitions in Mediterranean countries. Consumption, emissions and security of supplies.
No full textThis book analyses energy transitions, carbon dioxide emissions and the security of energy supply in Mediterranean countries. Unpacking the history of energy transitions, from coal to oil and natural gas, and from non-renewable to renewable energy sources, the book offers a comparative approach to the major trends in energy consumption, production, trade and security in Mediterranean countries in Europe, the Middle East and North Africa
Energie rinnovabili ed emissioni di CO2 nei paesi del Mediterraneo
No full textObiettivo del presente capitolo è quello di analizzare il ruolo delle energie rinnovabili nell’area Mediterranea1, evidenziando le differenze tra i paesi facenti parte dell’Unione europea e quelli appartenenti ad altre aree, come il Nord Africa e il Medio Oriente. Un altro aspetto importante che verrà analizzato riguarda le emissioni di CO2, che risultano notevolmente cresciute nel corso degli anni. Anche in questo caso metteremo in evidenza le importanti differenze tra le diverse economie facenti parte del Mediterraneo. Il problema del cambiamento climatico assume una posizione prioritaria nell’agenda politica di molti governi, e da questo punto di vista il Mediterraneo richiede un’attenzione particolare, poiché la forte crescita della domanda di energia da parte dei paesi del Nord Africa e del Medio Oriente porterà a un ulteriore incremento delle emissioni di CO2. È su questi temi che si soffermerà il presente capitolo, nel quale verranno analizzati anche alcuni aspetti del partenariato Euro-Mediterraneo sul tema dell’energia e delle fonti rinnovabili
A long-term analysis of efficiency in the Italian banking system from 1861 to 2010
Full text linkIn this paper, we analyse the performance of the Italian banking system in the 1861–2010 period. In this regard, we apply a stochastic frontier analysis cum ARDL procedure. First, we implement stochastic frontier analysis to the cost function of the Italian banking system in order to identify the years in which the banking system allocated its resources most efficiently. To this end, we propose a version of the stochastic frontier in which the inefficiency term is modelled as a linear function of the capital ratio and of the non-core ratio. The underlying hypothesis is that the efficiency of the banking system is guided by its degree of solvency and stability (capital ratio and non-core ratio, respectively). Finally, in order to verify the existence and stability of a long-term relationship between banking efficiency and capital ratio and non-core-ratio, we implement ARDL estimation. In so doing, we verify whether solvency and stability are two important factors in determining the efficiency of the Italian banking system in the long run. We show that the efficiency of the banking system is influenced negatively by the non-core ratio and positively by the capital ratio, respectively. Finally, only the non-core ratio influences the efficiency of the Italian banking system in the long run

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
