Quality Determinants and Effect of Therapeutic Properties in Honey Consumption. An Exploratory Study on Italian Consumers
2019
Nowadays, more and more consumers show a growing interest in healthy food products that may help to maintain or improve human health, such as honey. Honey has always represented a fundamental component of traditional medicine in many world cultures. However, only thanks to several studies carried out in the last years, its use is considered as an alternative and complementary medicine, namely apitherapy. In this way, honey is recognized increasingly by consumers not only as a natural alternative to refined sugar but as healthy food, as shown by determining an increase of its consumption worldwide. This study aims to explore the consumers&rsquo
Ecovillages in Spain: Searching an emancipatory social transformation?
2018
Today the second most important country after the United States, in the number of ecovillages, and by far, the most prominent in Europe, is Spain. The question to be addressed here is whether this revival or boom of ecovillages in Spain is an incipient social transformation and cultural change, following Erik Olin Wright theory of emancipatory social transformation. This work is divided into five main sections. The first one introduces three different approaches that remark the importance of ecovillages for radical cultural and social studies. The second part explains the methodology performed for the study of 29 ecovillages in Spain, using six critical variables on material interests and i…
Playing with accents
2020
While certain ways of speaking or varieties of English – such as American English or British English – evoke associations of modernity, higher education and urbanity in Uganda, others – such as Ugandan English with strong northern or western accents – stand for backwardness, social strata remote from education and ‘village identities’. Yet concepts of backwardness or modernity are not only based on linguistic criteria but also associated with a specific worldview, contributing to complex signs of higher-order indexicality. In contrast, speakers’ practices of enregisterment reveal how fluid and contextual these indices of urbanity and rurality actually are. Considering diverse repertoires of…
Drone arc routing problems
2018
[EN] In this article, we present some drone arc routing problems (Drone ARPs) and study their relation with well-known postman ARPs. Applications for Drone ARPs include traffic monitoring by flying over roadways, infrastructure inspection such as by flying along power transmission lines, pipelines or fences, and surveillance along linear features such as coastlines or territorial borders. Unlike the postmen in traditional ARPs, drones can travel directly between any two points in the plane without following the edges of the network. As a consequence, a drone route may service only part of an edge, with multiple routes being used to cover the entire edge. Thus the Drone ARPs are continuous o…
A New Branch-and-Cut Algorithm for the Generalized Directed Rural Postman Problem
2016
The generalized directed rural postman problem, also known as the close-enough arc routing problem, is an arc routing problem with some interesting real-life applications, such as routing for meter reading. In this article we introduce two new formulations for this problem as well as various families of new valid inequalities that are used to design and implement a branch-and-cut algorithm. The computational results obtained on test bed instances from the literature show that this algorithm outperforms the existing exact methods
The directed profitable rural postman problem with incompatibility constraints
2017
[EN] In this paper, we study a variant of the directed rural postman problem (RPP) where profits are asso- ciated with arcs to be served, and incompatibility constraints may exist between nodes and profitable arcs leaving them. If convenient, some of the incompatibilities can be removed provided that penalties are paid. The problem looks for a tour starting and ending at the depot that maximizes the difference between collected profits and total cost as sum of traveling costs and paid penalties, while satisfying remaining incompatibilities. The problem finds application in the domain of road transportation service, and in particular in the context of horizontal collaboration among carriers …
Peace Mediations: Recourse to the Arbitration in the kingdom of Valencia (XIV-XV Centuries)
2017
Arbitration, as a means of conciliation, had an extraordinary diffusion in the Medieval West. It had the advantage of being more quick and, generally, less expensive that the causes resolved by the ordinary courts. Moreover, it tried to reconcile the interests of the warring parties. This paper seeks to define the main features of the arbitration in the kingdom of Valencia during the Middle Ages focusing the observation on the small rural community of Vilafranca.
Las voces del interior rural valenciano: recursos naturales y resistencias al desarrollo
2020
[EN] This paper shows the results of two territorial diagnoses for employment and local development carried out in two rural regions of the province of Valencia. These diagnostics showed that these territories have abundant natural resources, but that lack of competent actors to dynamize them properly; either because they lack the means to do so (access to sources of financing, transport or basic infrastructure), or because they are not trained for it (aging population with lack of training), or because they do not have enough initiative (installed in a comfort zone).
De la maison au " village" . Les origines de la morphologie de l'habitat dispersé dans les montagnes de la Savoie du nord
2002
Dans les hautes vallées savoyardes, le peuplement d'avant l'invasion touristique était caractérisé par une implantation en hameaux dispersés à travers le territoire communal. Dispersion relative en Savoie du sud (Maurienne, Tarentaise, Combe de Savoie) où les hameaux étaient fédérés par un « chef-lieu » qui était un véritable bourg ; dispersion fréquemment absolue en Savoie du nord (Faucigny, Chablais), où le chef-lieu n'avait souvent pas plus d'importance que les écarts. C'est aux massifs mo...
Formulations and exact algorithms for the distance-constrained generalized directed rural postman problem
2017
[EN] The generalized directed rural postman problem is an arc routing problem with many interesting real-life applications, such as routing for meter reading. In this application, a vehicle with a receiver travels through a series of neighborhoods. If the vehicle gets closer than a certain distance to a meter, the receiver is able to record the gas, water, or electricity consumption. Therefore, the vehicle does not need to traverse every street, but only a few, to get close enough to each meter. We study an extension of this problem in which a fleet of vehicles is available. Given the characteristics of the mentioned application, the vehicles have no capacities but there is a maximum distan…
