Il corto circuito della Robin Tax
No full textIl decreto legge 13/08/2011, n.138 prevede alcune novità in merito alla cosiddetta "Robin Hood Tax": l'innalzamento dell'aliquota addizionale Ires per le società operanti nel settore energetico per i periodi di imposta dal 2011 al 2013; l'estensione dell'addizionale Ires ai soggetti che svolgono attività regolate sia nel settore elettrico che in quello del gas col divieto di traslazione di tale imposta ai clienti finali; l'estensione di predetta addizionale anche ai soggetti che producono elettricità da biomasse e fonte solare-fotovoltaica o eolica, finora esclusi; la riduzione della soglia di fatturato che determina l'assoggettamento all'imposta.
La Robin Hood Tax è stata introdotta nel giugno 2008, e la situazione attuale, almeno per quanto riguarda i fondamentali economici, è profondamente diversa. Tuttavia, il fine di recuperare in tempi brevi e certi (dopo aver per anni colpevolmente sottovalutato i rischi della congiuntura) non può giustificare l'adozione di misure approssimative, che prefigurano rilevanti "rotture" di equilibri tra i poteri, pesanti contenziosi con il conseguente carico di incertezze, benefici economici inferiori a quelli che verrebbero apportati da un corretto sviluppo economico-finaziario del settore energia, esponendo il nostro Paese al rischio dell'abbandono da parte degli investitori nazionali ed internazionali
Percutaneous coronary intervention following thrombolysis: for whom and when?
No full textrimary percutaneous coronary intervention (PPCI) is the treatment of choice for patients with ST segment elevation myocardial infarction (STEMI). In the attempt to reduce the unfavourable effects of time delays before PPCI, the administration of thrombolysis has been advocated (facilitated-PCI), but this treatment was shown to be ineffective and harmful, and should be avoided in patients who can receive PPCI promptly. Fibrinolysis is still indicated when PPCI is not available within 90120 min but 1/3 of STEMI patients undergoing fibrinolysis does not show signs of reperfusion and even when reperfusion is achieved they have a considerable risk of death and recurrent MI. Thus invasive management with early PCI could be complementary to fibrinolysis both to obtain coronary reperfusion in those patients with failed thrombolysis (rescue-PCI) and to decrease the risk of further ischaemic events in patients with successful thrombolysis. In this article we show that this synergy has been supported by modern randomized control trials and meta-analysis. It is advisable that organization model of territorial network for the treatment of STEMI patients should be expanded to provide a timely access to hospital with interventional facilities also to patients treated with fibrinolysis that need rescue-PPCI or an urgent/early invasive managemen

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
