The policy and the politics on energy in Italy
No full textTo date no National Energy Program (NEP) exists in Italy.Since 1998 (so called “Bassanini law”), Italian Regions are allowed to conceive, elaborate and issue their respective Regional Energy Plans (REP’s). The State would retain the power of addressing the National energy policy, by:
1. setting out the strategic milestones at nation’s scale
2. harmonizing the various REP’s
Identification of a genetic element (psr) which negatively controls expression of Enterococcus hirae penicillin-binding protein 5
No full textEnterococcus hirae ATCC 9790 produces a penicillin-binding protein (PBP5) of low penicillin affinity which under certain conditions can take over the functions of all the other PBPs. The 7.1-kb EcoRI fragment containing the pbp5 gene of this strain and of two mutants, of which one (E. hirae R40) overproduces PBP5 and the other (E. hirae Rev14) does not produce PBP5, was cloned in pUC18 and sequenced. In the 7.1-kb EcoRI fragment cloned from strain ATCC 9790, an open reading frame (psr) potentially encoding a 19-kDa protein was identified 1 kb upstream of the pbp5 gene. An 87-bp deletion in this element was found in the 7.1-kb EcoRI fragment cloned from strains R40 and Rev14. In addition, several base substitutions were found in the pbp5 genes of strains R40 and Rev14. One of these converted the 42nd codon, TCA, to the stop codon, TAA, in the pbp5 gene of Rev14. Escherichia coli strains were transformed with plasmids carrying the 7.1-kb EcoRI insert or a 2.6-kb HincII insert containing only the pbp5 gene of the three strains. Immunoblotting analysis of proteins expressed by these transformants showed that the 87-bp deletion in psr was associated with the PBP5 overproducer phenotype of strain R40 and the conversion of the TCA codon to the stop codon was associated with the PBP5 nonproducer phenotype of strain Rev14. None of the other nucleotide substitutions had any apparent effect on the level of PBP5 synthesized

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
New scenarios for the Palmaria island (Porto Venere- Ligurian Sea)
No full textThe Palmaria island in the municipality of Porto Venere between the Gulf of La Spezia and the Cinque Terre (Italy) is a complex and integrated system, consisting of several cultural heritage. The way to arrive at a vision of global landscape, understood as the network connection of all the other elements of great historical value begins in 1939 (law no 1497) when the site was declared of great public interest and the landscape has been protected as a single asset with a landscape bond. In 1997, after being recognised as a World Heritage Site, the aims of the active management of this area were: public reuse of the historical and cultural buildings, revaluation of the landscape as an integrated system composed by many singular and peculiar elements and promotion of an alternative cultural tourism compatible with the conservation of the landscape. In 2016 the State Property Agency signed a understanding memorandum with the Ministry of Defence, the Navy, the Liguria Region and the Municipality of Porto Venere for the enhancement of more than 100 public property, including buildings and land, present in the Palmaria Island. How will change the landscape of the island after these agreements between public authorities? The intent of this study is to propose guidelines for an integrated and sustainable management of this unique coastal landscape with the aim of promoting cultural tourism without harming the local population. The landscape is understood as 'a sheet without seams' and becomes the connection of the historical, cultural and natural elements of both land and sea. Within this network some pilot projects are proposed, that contribute to the development of a sustainable tourism model, responding to different needs of different social categories that frequent the area. Among the topics studied: the regeneration of the landscape, the revaluation of the history, traditions and cuisine, the recovery of the relationship with the sea as a landscape value, intelligent reuse of public buildings with existing cultural and historic value
