Conventions of Quality in Consumer Preference toward Local Honey in Southern Italy
2016
During the last few decades consumer demand for local foods has increased around the world, particularly in the USA and Europe. Such consumer trend also contributes to redefine a new alternative geography of food; in which local foods are perceived to be of better quality and safer. Moreover, consumers frame local food quality not only in terms of general attributes, such as taste and price, but also in terms of more subjective attributes closely linked to social and environmental aspects of products. These attributes are recognised by consumers as a range of socially constructed food quality criteria, which play an important role in the creation of information about quality and consumer de…
Modeling sequential production: the migratory beekeeper case
2018
This paper formalizes a bio-economic model of migratory beekeeping activities, during the annual production cycle, so as to discern the optimal sequence of foraging sites for migratory beekeepers; it then proceeds to empirically verify the model via a case study. The model assumes that the apiary farm produces three marketable outputs under conditions of certainty with disjunctive resources at the sites. In particular, honey, commercial pollination services and nucleus colonies are produced sequentially at foraging sites throughout the year. The model determines a migratory beekeeperâs revenues, variable costs, gross income from each sequence of foraging sites under the constraint that th…
An exploratory analysis of website quality in the agrifood sector: The case of extra virgin olive oil
2018
Besides verifying the current consistency on the Internet of websites set up by Sicilian (Southern Italy) EVO oil firms, this paper aims to verify their e-service quality by evaluating which main quality features, as derived from the literature, they have. To process the data, descriptive statistics were used, which allowed detection of the presence/absence of the variables examined. The study found 280 websites with some qualitative gaps. Findings highlight that EVO oil firms do not exploit the potentialities of the web adequately. They often use the Internet as a communication and promotion tool, but only to a lesser degree for e-commerce. The results may be useful to both agrifood manage…
Purification of recovered phosphoric acid by extracting aluminium with di-2-ethylhexyl phosphoric acid
2021
AbstractThe extraction of aluminium from dilute phosphoric acid with di-2-ethylhexyl phosphoric acid (DEHPA) was optimized using response surface methodology. The optimization was based on the experimental three-level central composite face-centred design (CCF) and was conducted on real-life samples. The three variables included were pH, extractant concentration and aqueous to organic phase ratio (AO). Under the optimized conditions (pH 2.5, 0.6 M DEHPA and AO ratio 1:2), extraction efficiency of 99% for aluminium in four extraction stages is achieved. The purified phosphoric acid solution can then be utilized by the fertilizing industry. Stripping tests for organic phase loaded with alumin…
Integrated photonic routers driven by surface acoustic waves
2016
Durante la segunda mitad del siglo XX se produjo un desarrollo excepcional de la capacidad de transmitir y procesar información electrónicamente. Esto fue debido en parte a la capacidad de integrar en un único substrato una gran cantidad de transistores, que son las unidades fundamentales de procesamiento de datos. Este comportamiento quedó resumido en la ley de Moore, que predecía que el número de transistores integrados se duplicaría cada 24 meses. Esta tendencia, que se ha mantenido hasta la actualidad con transistores de tamaño nanométrico, no puede continuar indefinidamente. Uno de los problemas fundamentales reside en la capacidad limitada para disipar el calor que generan los disposi…
Combatientes de un nuevo cuño: supervivencia y comunidad en los primeros testimonios del exilio
2009
El artículo describe algunos de los núcleos de sentido que acompañaron a la publicación de los testimonios de supervivientes chilenos en los primeros años del exilio. Especialmente, el modo en que la escritura testimonial fue legitimada por la voz autorizada de importante figuras de la Unidad Popular que convirtió a los supervivientes que aportaban su testimonio de la violencia en ‘combatientes de un nuevo cuño'. El artículo analiza el modo en que los supervivientes respondieron en sus textos a esa expectativa política tratando de resguardar en ellos las concepciones de la experiencia, de la política y de la comunidad que habían vertebrado los compromisos de la ‘vía chilena al s…
The contribution of a supplier of the food and beverage industry to the sustainability of the overall supply chain
2021
Achieving sustainable scopes in a supply chain context entails structural changes at all tiers. Recently, scholars investigated different models able to achieve a sustainable supply chain management. With the aim to explain which factors, at the single supplier level, could reassure a focal firm as regards the compliance of sub-suppliers toward sustainability principles, a case study was performed on a company of the food and beverage packaging industry, based on the natural resources-based view of the firm. Results show the leading role that, a major supplier, can play in promoting sub-suppliers' compliance towards sustainable principles. Reputation, legitimacy and concerns about future po…
Stakeholders' involvement in establishing sustainable business models
2020
PurposeCooperatives play a dominant role in the European dairy sector. The aim of the study is to define a sustainable business model of dairy cooperatives and explore how stakeholders can contribute to innovation processes generated in this ecosystem.Design/methodology/approachStarting from theoretical assumption and investigation of three major cooperatives located in an ecological agricultural Poland region, known also as “Green Lungs of Poland,” the authors propose a sustainable business model where the role stakeholders in the value co-creation is emphasized.FindingsThe findings of this paper show how the involvement of various stakeholders by the cooperatives contributes to the develo…
Sustainability and New Models of Consumption: The Solidarity Purchasing Groups in Sicily
2011
Social embeddedness, defined as the interaction of economic activities and social behavior, is used in this study as a conceptual tool to describe the growing phenomenon of food community networks (FCNs). The aim in this paper was to map the system of relations which the FCNs develop both inside and outside the network and, from the number of relations, it was inferred the influence of each FCN upon the formation of new socially embedded economic realities. A particular form of FCN was taken under consideration: solidarity purchase groups (SPGs). Performed with the aid of social network analysis on a sample of SPGs in Sicily (a region in southern Italy), the study allowed us to identify a r…
PAYMENT FOR ENVIRONMENTAL SERVICES FOR THE SUSTAINABLE DEVELOPMENT OF THE TERRITORY
2014
Over the last years the interest in environmental s ervices provided by forests has considerably grow. This situation, in developed countries, derive from risi ng demand of new goods and services tied to landsca pe use and leisure activities. These can be considered such as no woody products and they represent externalities produced by forest that, if suitably utilized, could produce value for the area and earn ings for people living near forests. From an economic point of view, at the aim of providing these services, it is necessary the introduction of a suitable payment sy stem or, in alternative, a situation in which posit ive externalities of landscape, in sync with other good s/service…
