Fonti alternative di approvvigionamento idrico: la desalinizzazione. La legge “SalvaMare” e il passo indietro del decreto “Siccità”. Innovazioni sostenibili
No full textWater is an essential resource for life and a fundamental human right. Drought and global warming are increasingly affecting larger geographical areas. Desalination helps increase water supplies but has significant impacts on ecosystems and health. Article 12
of Legislative Decree No. 60 of 2022 – the “SaveSea” law – addressed a genuine legislative gap by subjecting the construction of such plants to environmental impact assessment procedures, marking a step forward in environmental protection, shortly followed
by a regulatory setback. Legislative Decree No. 39 of 2023, converted into Law No. 68
of 2023 – the “Drought” decree – significantly scaled back the scope of Article 12, subjecting desalination plants with a capacity equal to or greater than 200 l/s to a verification
of the need for an environmental impact assessment, leaving out larger plants that could
significantly affect the environment. An innovative and more sustainable alternative to
land-based plants is represented by mobile desalination
Turismo sostenibile e gestione dei conflitti: il difficile equilibrio tra conservazione e sviluppo
No full textIl turismo è un settore industriale rilevante che può avere un impatto significativo a
livello economico, sociale e ambientale. Pertanto, le sfide legate allo sviluppo sostenibile hanno una
rilevanza specifica nel contesto del turismo. Questo articolo si focalizza sul significato e le applicazioni
della nozione giuridica di turismo sostenibile. Gli elementi caratterizzanti la nozione possono essere
ritrovati negli strumenti internazionali riguardanti lo sviluppo sostenibile (in particolare, l’Agenda
2030 delle Nazioni Unite) e il turismo, specialmente nel contesto dell'Organizzazione Mondiale del
Turismo delle Nazioni Unite (UNWTO). Altre indicazioni arrivano dal diritto europeo e dal diritto
italiano. Il contributo muove da questo contesto per mettere in evidenza e analizzare i principi e gli
interessi contrastanti alla base dell’idea di sviluppo sostenibile e turismo sostenibile: la chiave di
lettura proposta per la comprensione e la soluzione di questi contrasti può essere vista nelle ultime
tendenze nel diritto europeo e italiano, che sottolineano l’importanza delle componenti ambientali ed
ecologiche della sostenibilità. Da un altro punto di vista, il conflitto può tradursi sul piano
istituzionale in un difficile esercizio delle competenze coinvolte nella regolamentazione del turismo: il
problema - molto attuale - del cd. “overtourism” offre interessanti casi di studio, che mostrano come
l’evoluzione della regolazione richieda necessariamente un dialogo tra diversi livelli di governo, oltre
all’impiego di nuovi strumenti normativi o l’adattamento di quelli esistenti
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
