No full textPolicy management of the Italian small pelagic fishery in the Adriatic Sea: A dynamic maximum economic yield approach
No full textThe sustainability of most Mediterranean fisheries is heavily compromised, suggesting the need for an effective policy response to preserve both profitability of fleets and fish stocks in the long run. This study focuses on the Italian small pelagic fleet in the Adriatic Sea. More specifically, we focus on anchovies and sardines' stocks, which account for most of the total catches in the area in terms of landed weight. We build an optimization model aimed at estimating the discounted Maximum Economic Yield (MEY) of this fishery under selected policy scenarios ranging from effort limitations to total allowable catch (TAC) management. The model allows us to compare the bioeconomic performances of the fishery over a time span of 10 years. The results outline a trade-off between biological and economic policy targets, as well as an efficiency gap among fishing gears. This gap ultimately leads to an uneven distribution of economic benefits under restrictive policy scenario
La fiducia nel processo di certificazione e i comportamenti di acquisto dei prodotti biologici
No full textLa filiera d’acquisto dei prodotti biologici ruota attorno al sistema di certificazione che garantisce al consumatore il rispetto di standard di processo e di attributi del prodotto stabiliti a livello normativo. Da un punto di vista della teoria microeconomica la certificazione da enti terzi rappresenta la soluzione teorica e pratica per eliminare il processo di selezione avversa e azzardo morale che possano minare la fiducia e la credibilità del sistema. Perciò, politiche che possano giovare alla fiducia ed alla credibilità del sistema di certificazione sono considerate misure che possano influenzare ugualmente anche i comportamenti di acquisto dei prodotti biologici. In questo articolo attraverso modelli di scelta discreta dimostreremo che questo nesso logico potrebbe non essere così scontato in quanto la fiducia rappresenta solo condizione necessaria ma non sufficiente per guidare le scelte di acquisto data la molteplicità dei fattori che risultano determinanti
Farming in the shadow of violent organizations: understanding farmers’ relational place-making in socio-ecological crises
Full text linkThis study investigates how farmers develop place-based relations when subject to structural conditions of violence and environmental crime. We particularly focus on environmental crimes perpetrated by the Camorra, the Neapolitan Mafia, at the expense of farming communities in the metropolitan areas of Naples and Caserta, in Italy. Farmers located in this area have struggled to mobilize collectively, with only a group of farmers enable to re-act to land exploitation, illegal burning or dumping, and more in general to the waste crisis. Stimulated by this rather puzzling empirical evidence, our research team engaged in a deeper investigation of the waste crisis, exploring how farmers located in the Land of Fires reacted to conditions of violence and environmental crime by developing a differentiated set of place-based narratives and practices. Using the Land of Fires and the waste crisis as an empirical context, in this study we focus particularly on conceptualizing place-based processes emerging in the context of organized violence and environmental crime. In our approach, these are structural conditions produced by the Camorra and the state, to which local agencies, such as farmers, respon

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
