Nuovi strumenti di politica ambientale. Gli accordi volontari.
No full textGli accordi volontari si sono recentemente affermati nei paesi industrializzati come uno degli strumenti della politica ambientale e, più in generale, della politica industriale, nell'ambito di una crescente tendenza alla cooperazione tra pubblica amministrazione ed imprese.
Non è solo l'insufficienza dei tradizionali strumenti regolamentativi nell'affrontare problemi ambientali sempre più complessi a favorire la diffusione degli accordi volontari, ma anche una serie di loro caratteristiche intrinseche, soprattutto in termini di flessibilità e di creazione del consenso, che ben si adattano all'applicazione in contesti industriali ed in sistemi territoriali specifici e diversificati.
Nel volume, frutto di una approfondita ricerca condotta dallo Iefe - Università Bocconi, vengono esaminate le modalità di sviluppo degli accordi volontari in Italia, sulla base di un censimento complessivo e dell'analisi di alcuni casi emblematici, a livello nazionale e regionale/locale, che vedono coinvolte istituzioni centrali e locali, grandi imprese, associazioni industriali e consorzi obbligatori e volontari.
L'esperienza italiana viene confrontata con quella degli altri Paesi europei - sulla base di una recente indagine dell'Agenzia Europea per l'Ambiente - e con quella statunitense. Ne emergono importanti differenze, ma anche punti in comune, quale il ruolo critico svolto dai sistemi di controllo e, più in generale, dalle modalità di gestione dell'informazione.
Particolarmente rilevante per l'ulteriore diffusione degli accordi volontari, risulta l'evoluzione del quadro normativo-istituzionale, sia a livello nazionale che comunitario.In entrambi i casi è in corso uno sforzo di formalizzazione degli accordi volontari che, senza comprometterne la flessibilità, ne consenta un impiego più equo, misurabile in termini di risultati e trasparente.
Si tratta comunque di una dinamica ancora fluida, i cui esiti possono avere un rilevante impatto sulla competitività del sistema industriale nazionale
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
