Influence of new factors on global energy prospects in the medium term: comparison among the 2010, 2011 and 2012 editions of the IEA’s World Energy Outlook reports”
Several economic, geopolitical, demographic and environmental factors drive world’s energy scenario; among them, the reduction of greenhouse gases emissions and the consequent development of renewable energy sources, the global financial crisis, the increase in global population and urbanization, the increase of fossil fuels prices have had a particularly strong impact in recent years. Furthermore, exceptional events, such as the accident at the Fukushima nuclear power plant in Japan, may occur to complicate World energy scenarios.
The most recent reports on world energy markets, especially the WEO - World Energy Outlook, are characterized by the introduction of new prospects and scenarios, as a result of unpredictable events such as Fukushima accident or of emerging factors, such as the increasing share of unconventional resources in the future energy mix (shale gas and shale oil) and the importance of energy efficiency, proposing an “Efficient World Scenario”. Disappointing signals about the development of renewables are also recorded.
The paper focuses on the comparison among the major reports and statistical energy data, especially the 2010, 2011 and 2012 editions of the World Energy Outlook issued by IEA. Mid-term energy scenarios are presented and discussed, with particular emphasis on the increasing importance of energy efficiency, on the new prospects concerning nuclear power and on the role of unconventional fossil fuels
LA TERMOVALORIZZAZIONE DEI RIFIUTI SOLIDI URBANI Aspetti energetici, tecnologici, legislativi ed ambientali
Dopo una breve rassegna di dati statistici sulle modalità di smaltimento dei
rifiuti in Italia e all’estero, il lavoro affronta il problema del contenuto energetico
dei rifiuti e dell’influenza della raccolta differenziata, e presenta un panorama
aggiornato delle Bat (Best Available Technologies) per quanto riguarda sia i
forni di combustione che i dispositivi di abbattimento degli inquinanti prodotti
dagli impianti di termovalorizzazione. Completano il lavoro una rassegna
normativa sulle emissioni dei termovalorizzatori, la descrizione di alcune
esperienze impiantistiche significative e un confronto tra discarica e

Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
