IL DUPLICE RUOLO DELL’ENERGIA: MOTORE DELLO SVILUPPO E MINACCIA PER L’AMBIENTE
No full textLe risorse di petrolio e di gas naturale, in quanto fonti non rinnovabili, sono destinate all’esaurimento. E’ quindi
estremamente importante affrontare il problema energetico attraverso un accurato disegno pianificatorio che tenga conto
delle esigenze sociali primarie. Una componente importante e in costante aumento dei consumi energetici è quella elettrica,
che, soprattutto nel nostro Paese, in buona misura si basa e si baserà per molti anni sull’utilizzo dei combustibili fossili,
nonostante le possibilità non ancora sfruttate nei settori dell’energia nucleare, dell’energia idraulica, delle biomasse,
dell’energia solare ed eolica. Occorre quindi sviluppare ricerche che ci consentano in tempi ragionevoli di poter disporre di
nuove fonti energetiche, ma parallelamente rendere la convivenza con le fonti fossili la più sostenibile possibile, tenendo
conto che la combustione degli idrocarburi genera danni importanti all’ambiente. Per conseguire tali obiettivi si devono
soddisfare due requisiti irrinunciabili: un elevato livello di conoscenze diffuse sui problemi dell’energia e dell’ambiente e
il ricorso a processi innovativi che consentano di sfruttare in modo più razionale e più ambientalmente compatibile il
contenuto energetico delle fonti fossili: si tratta pertanto di elevare il più possibile i rendimenti dei processi di conversione
dell’energia e di ridurre al minimo gli impatti ambientali
The Drivers of Customer Satisfaction for Academic Library Services. An Empirical Study on Two Italian University Libraries Using the Kano Model
No full textThe aim of this paper is to analyze the library services of two Italian Universities (the Faculty of Economics of University of Palermo and the Central Library of the University of Salerno) to find relations and congruencies and to evaluate the perceived relevance of the tangible and intangible aspects of these services. The results show the characteristics that are relevant for the customer satisfaction of users of this service.
This study supplies a significant analysis of qualitative data that can be functional for researchers and for university managers to plan strategic and operative activities in order to improve academic library services
University incubator as catalyst of resources for academic spin-offs. The case of ARCA Consortium
No full textToday we can observe an increasing proliferation of new academic spin-off initiatives aimed to
transfer knowledge from the university to the market. Due to their strategic role in enhancing the development of technological innovation, academic spin-offs can attain high levels of social performance and consonance with their environment. At the same time, they must overcome many difficulties if they are to achieve a high level of financial performance and growth. They are often considered to be mere vehicles for the transmission of knowledge, implying that their entrepreneurial potential is not fully exploited. According to the Resource
Based View (RBV) the competitive disadvantage of an academic spin-off is due to a lack of resources. This paper will join this stream of research in order to analyze the financial performance of academic spin-offs. We examine the case of Arca Consortium’s incubator, established by the University of Palermo, and of the academic spin-offs it has supported and continues to assist. The empirical analysis, based on two linear regression models, is performed based on 19 case studies of spin-offs created between 2007 and 2009 by
academicians of the University of Palermo
Innovazione e imprenditorialità. Il ruolo degli spin-off universitari.
No full textOggi il ruolo delle Università non si limita più soltanto alle tradizionali attività di formazione e di ricerca.
La cosiddetta Seconda Rivoluzione Accademica ha attribuito alle Università una "terza missione", che consiste nella valorizzazione e commercializzazione della conoscenza accedemica sul mercato. L'Università diviene così "entrepreneurial university" creando valore non solo in termini di conoscenza ma anche di innovazione e sviluppo economico.
Il libro intende approfondire il ruolo che le Università rivestono nel processo di trasferimento di conoscenza innovativa al mercato tramite la costituzione di imprese spin-off. Viene evidenziato come, attraverso il supporto di apposite strutture definite "incubatori" universitari, l'università sia in grado di creare l'humus per dar vita a start-up innovative, in grado di competere e contribuire allo sviluppo economico
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
