I primi dati del distretto : una ricerca su 7 aree rurali lombarde
No full text• Il progetto DES rappresenta un territorio fertile per lo sviluppo dei Local Food System
• I primi dati disponibili indicano una profonda differenza tra i territori oggetti di studio – Il contesto della Valtellina mostra le potenzialità per progetti locali più strutturati grazie sia ad una buona varietà di prodotti
disponibili sia alla predisposizione degli imprenditori agricoli
verso queste tematiche.
– Il contesto dell’Oltrepò Mantovano necessita di maggiori
attenzioni da parte delle politiche locali per stimolare gli
imprenditori agricoli. Da questo punto di vista progetti locali,
anche di piccole dimensioni, potrebbero rappresentare un
valido supporto allo sviluppo di una cultura imprenditoriale
attenta allo sviluppo locale. La ristorazione collettiva potrebbe rappresentare una
valida driving force dei Local Food System analizzat
I gruppi di azione locale : driving force dei Sistemi agricoli locali
No full textNel corso degli ultimi anni, le crescenti esigenze in termini di sostenibilità delle attività produttive e di consumo unite al progressivo deterioramento della redditività degli investimenti agricoli hanno spinto i diversi stakeholder del settore agro-industriale a studiare nuove forme di organizzazione dei sistemi agricoli. In particolare, tale ricerca ha individuato nei Sistemi Agro-alimentari Locali (SAL) una possibile soluzione al complesso dilemma crescita-sostenibilità. I SAL possono essere definiti come sistemi alternativi al modello alimentare globalizzato che si fondano su complessi rapporti tra produzione agricola, trasformazione, distribuzione e consumo in un determinato luogo (Dunne et al., 2011). Tali sistemi rappresentano un’ambiente privilegiato per promuovere modelli di produzione-consumo sostenibili; tuttavia, l’elevata complessità che li caratterizza necessita di una governance forte in grado di coniugare le diverse esigenze di attori provenienti da realtà molto diverse. In quest’ottica i Gruppi di Azione Locale (GAL) possono rappresentare un valido strumento di orientamento e coordinamento al servizio dei SAL (Ferrazzi et al., 2013).Il progetto DES ha evidenziato l’importanza dei SAL e la necessità di una governance in grado di gestire e coordinare attori che appartengono a realtà produttive e sociali differenti. In questo senso, i GAL rappresentano, senza dubbio, un importante strumento a sostegno dello sviluppo del territorio data la loro capacità di rappresentare una molteplicità di interessi.
La ricerca effettuata presso le imprese agricole ha messo in luce profonde differenze tra i territori oggetto d’indagine sia in relazione alle caratteristiche tecnico-produttive sia per quanto riguarda gli aspetti organizzativi e la propensione all’innovazione. A tal riguardo è emersa, come elemento centrale, la necessità di orientare le imprese attraverso la formazione e favorendo, specie in alcuni territori, il ricambio generazionale.
Lo studio dell’offerta potenziale di prodotto veicolabile attraverso canali innovativi a filiera corta e locale collegati al progetto DES ha portato ad individuare, per ciascun territorio, le produzioni più adatte dal punto di vista qualitativo e quantitativo in relazione al canale stabilito. In questo senso, la ristorazione collettiva, individuata da diversi GAL come interessante forma di domanda organizzata, sembra possedere le caratteristiche adatte per diventare una driving force strategica per lo sviluppo dei SAL. Gli oltre 180 milioni di pasti2 annui della ristorazione scolastica, ospedaliera e delle RSA presenti in Regione Lombardia rappresentano, infatti, un’occasione importante per le produzioni del territorio e, più in generale, per l’economia locale stess

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
Exploring the relationship among local conflicts and territorial vulnerability: The case study of Lombardy Region
No full textDuring the last 10 years, opposition by local communities against the development of industrial facilities, energy technologies and transport infrastructures has steadily grown. Negative externalities on the environment, quality of life and health are the most frequent motivations of the opponents. Disputes are typically grounded in environmental, social and economic concerns about the local impacts of new development proposals. Within this context, this paper aims to explore the existence of a potential relationship between the level of territorial vulnerability and the distribution of local conflicts surveyed by the local and national press in the Lombardy Region (Italy). This type of relationship is investigated using an empirical analysis based on an overlay mapping of different informative layers. The vulnerability index has been calculated according to the most recent conceptual and analytical frameworks developed in the scientific literature. It is a multidimensional index grounded in environmental, social and economic criteria. The outputs of the vulnerability assessment have been placed into thematic maps to provide a comprehensive overview of the environmental and socioeconomic state of the Lombardy Region. In addition to the general degree of vulnerability, the maps display the local conflicts surveyed by the NIMBY Forum, an Italian survey of territorial disputes managed by the Agency of Research and Information Society. The maps provide a means of i) putting forward some hypotheses about the oppositions that have emerged around the localization of new facilities, including mainly industrial facilities, waste disposals, energy plants and transport infrastructures, and the vulnerability of the Lombardy Region; ii) identifying the driving factors of territorial vulnerability; iii) investigating whether the local oppositions are directly proportional to territorial vulnerability. The first results indicate that a direct relationship among territorial vulnerability and conflicts does not exist. This outcome, even on a preliminary basis, provides a new analytical perspective for understanding the reasons behind local community protests
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
