Investigating food losses and waste issue from a network perspective
No full textIn recent years, the negligent behaviour, wasteful management of resources, and simultaneously huge levels of undernourishment have been making the food loss and waste (FLW) issue more and more pressing: the seriousness of the problem stands out when also considering the consequent greenhouse gas emissions deriving from an useless production that remain in the atmosphere for thousands of years. The causes of food loss and waste can certainly be traced in the lack of proceduralisation along the agri-food chains and of knowledge transfer among stakeholders. A shared and proceduralised strategy that improves the effectiveness of the entire supply chain can certainly be a good starting point. Not-shared policies and strategies and missing proficient management of resources can be the possible causes. Several policy and research initiatives are in progress all over the world, but miscommunication and lack of knowledge seems to be the issue to be dealt with. Therefore, building a chain-oriented communication and innovative relational approach can represent a good strategy in order to reduce and to improve the FLW concerns. The aim of this paper is to propose a new methodological approach that analyses the FLW issue from a network perspective within the relationship between agri-food chain spatial proximity and relational networks. Social ties play a significant role in agricultural knowledge exchange, particular in countries very suited to agriculture and depending on rural structure. The assumption is that the chain works as a not oriented ‘path’ graph, that is weakly connected, or weak: it is expected that ‘missing networks’ or isolate nodes are characterized by a greater amount of FLW. Changing the agri-food chain in an oriented clique characterized by strong communication and relationship makes it possible to assign right position and role to different chain’s actors thus finding a new equilibrium aimed at decreasing FLW

Economic sustainability of the oil high and super-high density cropping systems in Italy
No full textThe analysis of the best production models is important to determine
the effects of different technical and economic choices on the farm’s
profitability. The estimation of the production costs represents a key element
for comparison among firms’ production costs, selling prices and used
technologies. This model can be adapted by the farmers for the calculation of
production costs and achieved economic margin. The present work shows a
comparison between the production costs of different olive oil growing
systems: high density system (HDS) and super high density system (SHDS)
through the analysis of costs and incomes’ pattern of the olive oil sector in the
Apulia region, the leading Italian region for olive oil production. In particular, a
modular calculation scheme was used. This system is aimed at determining the
efficiency benchmarks for olive production seeking to establish minimum
levels of economy and to determine which are the best performing systems
What are the conflicting tensions in an Italian cooperative and how do members manage them? Business goals', integrated management, and reduction of waste within a fruit and vegetables supply chain
No full textSocial enterprise is a model of hybrid organization driven by the need to generate positive externalities by reinvesting their surplus for social and environmental objectives. One of the biggest problems arising from joining financial goals with social goals is the presence of increasing tensions between the members and stakeholders involved. Nevertheless, there has not been enough focus on how managers, employees, and stakeholders respond to the tensions caused by contradictions and how they try to reach a balance between financial, environmental, and social goals. Therefore, the present study is aimed at investigating how members of an agricultural cooperative in the Apulia region (Italy) try to join the organizational forms of business and social values, namely, the sustainable practices related to CO2 emission reduction, resource use efficiency, and food waste mitigation. Additionally, the study goes further and explores whether and how these contradictory pressures are solved. Starting from the sensemaking approach, the study carried out an inductive case study through the use of a multiple case study design and in-depth interviews. The findings highlight the following two novel aspects: (1) Managers prefer to adopt a cumulative mitigating hybridization approach and (2) a weak integration can be noticed between social and commercial dimensions, originating from a lack of holistic perspective and poor interorganizational communication

Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
Louisiana red crayfish meal: a novel functional feed ingredient for organic fish diets?
No full textRed swamp crayfish is one of the most dangerous invasive alien species in Europe. This study investigates the nutritional value of a flash-dried whole meal as a novel possible ingredient in finfish diets. Based on the analysed nutrient composition and digestibility measured in rainbow trout, the flash-dried red swamp crayfish meal results to be a suitable complement or a partial alternative to conventional vegetable and/or animal protein sources in fish diets. Moreover, the high concentration of astaxanthin (a carotenoid with several positive physiological roles) makes it even more attractive also as a natural and functional ingredient for organic aquafeeds
