No full textDevelopment of a sustainability technical guide for the Italian olive oil supply chain
No full textItalian olive growing must aim at the transition to economically and environmentally sustainable management systems, linked to premium quality production and to a recognized and remunerated context of biodiversity conservation in compliance with the provisions of the European Union New Green Deal and United Nations Agenda 2030. To assist and facilitate companies in this step, a sustainability technical guide for the Italian olive oil supply chain has been developed, with reference to the four pillars of sustainability. The guide, consisting of 42 requirements, was submitted to 18 olive farms from 8 different Italian regions participating in this pilot study, to assess their level of total sustainability and to receive feedbacks throughout the drafting process. Taken as a whole, the companies have proved to be virtuous in meeting the requirements provided, with percentages of compliance ranging from 86 to 96% according to pillar and from 70 to 100% according to company and showed a remarkable spirit of collaboration and involvement in the construction of the guide. In this regard, the text is aimed to represent a participatory standard for Italian institutions and for other olive countries

No full textBiomassbed: a biological system to reduce pesticide point contamination at farm level
No full textA potential method for cleaning water from point-source pollution by organic compounds is using biological reactors. In this study, four reactors were tested for their ability to retain and degrade pesticides. The pesticides tested were the insecticide chlorpyrifos, the fungicide metalaxyl and the herbicide imazamox. The reactors were filled with differing mixtures of vine-branch, citrus peel, urban waste and public green compost. The reactor volume was 188 1. Forced circulation of the contaminated solution was programmed to decontaminate the solution. Both retention and degradation of the compounds by the reactors was studied.Chlorpyrifos was the best retained, due to its physico-chemical characteristics, while only one substrate effectively retained metalaxyl and imazamox (citrus peel + urban waste compost). Degradation of the pesticides in the reactors was faster than published values for degradation in soil. The half-life of all pesticides in the reactors was less than 14 days, compared to literature values of 60-70 days in soil. The combined retention and fast degradation make the biofilter a feasible technique to reduce spill-related and point environmental contamination by pesticides. The technique is most effective against persistent pesticides, while for mobile pesticides, the efficiency can be improved with several passages of the contaminated solution through biofilters

No full textGoing 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
Capri e gli architetti
No full textEsito di pluriennali e approfondite ricerche svolte in Italia e all'estero, il volume tratta in maniera sistematica le plurime interrelazioni tra l'isola di Capri - nella sua consistenza critica e nella sua valenza mitica - e la cultura architettonica nazionale e internazionale degli ultimi due secoli, concentrandosi sul denso e articolato succedersi di riflessioni e fantasie, rilevazioni e progetti, scritti e costruzioni.
Sulla base di nuove prospettive critiche e di molteplici materiali inediti, lo studio riesce così a mettere in luce i molteplici e pregnanti risvolti del rapporto tra Capri e gli architetti operanti tra Otto e Novecento. Sia per l'incanto dei suoi paesaggi, che per lo speciale fascino delle sue costruzioni spontanee, l'isola di Capri ha da sempre esercitato una particolare attrattiva sugli architetti. Per tutto l'Ottocento i progettisti europei - e soprattutto scandinavi, tedeschi e francesi - la considerano una tappa fondamentale del loro Grand Tour di formazione: disegnano con costanza fogli di grande qualità artistica, riprendono gli scenari urbani più pittoreschi, le costruzioni rurali più inusitate, elaborano fantasie grafiche per ricostruire idealmente con matita china e acquerello inquietanti resti di rovine romane. Allorché a fine Ottocento Capri diventa meta del turismo internazionale e luogo elitario di villeggiatura, pittori e scrittori scelgono l'isola come luogo ideale per sperimentare architetture speciali: dapprima nella linea dell'orientalismo, soggiogati dal fascino esotico dell'isola; in seguito rimeditando sui temi della classicità, rendendo omaggio ai tanti resti archeologici e alla memoria di Tiberio. Nel primo Novecento gli architetti sognano una mediterraneità fatta di linde case bianche in cui si incarna un'antica saggezza popolare ed eleggono quei luoghi incantati come scenari ideali per l'architettura moderna e per l'ideologia futurista
