Spatio-temporal composition of discard associated with the deep water rose shrimp fisheries (Parapenaeus longirostris, Lucas 1846) in the south-central Mediterranean Sea

Discarding in fisheries is the fraction of the total catch brought on board and returned to the sea dead or alive for legal or economic reasons. The reduction of discard is one of the main objectives of the European Common Fishery Policy. This study aimed to improve the current knowledge of the discard associated with the deep-water rose shrimp (DPS) fisheries in the south-central Mediterranean Sea. We analyzed data collected from January 2009 to December 2013. Multivariate data analysis and generalized additive models (GAMs) were used to assess the spatio-temporal composition of the discard (which represented 36% of the total catch) and factors influencing its distribution. Multiple analys…

A multi criteria decision making approach to support the risk management: a case study

Project risk management plays a fundamental role in the project management field. Project objectives may dynamically change in time, hence it is not easy to satisfy them, especially when related to complex projects. In detail, they can be subjected to several and different risk conditions which have an important impact on the project success. In this context, multi-criteria decision making (MCDM) methods are effective tools to carry out the risk management. In particular, the present research proposes the use of MCDM with a specific focus on the ELECTRE TRI method. The last one is able to evaluate and assign projects under analysis into ordered and different risk classes. The purpose consis…

Metamemoria

La memoria ha una rilevanza indiscutibile nei processi di apprendimento, in quanto ci permette di assimilare, ritenere e richiamare ciò che abbiamo appreso tramite l’esperienza e, su questa base, organizzare le nuove informazioni e conoscenze. In particolare, la memoria di lavoro (ML), in stretta connessione con quella a breve termine, ci permette di usare le informazioni immagazzinate temporaneamente per l’esecuzione di compiti cognitivi complessi. La ricerca ha inoltre dimostrato che buoni livelli di ML si correlano a un apprendimento efficace.Rivolto a bambini e ragazzi dai 6 ai 13 anni, Metamemoria rappresenta una proposta efficace e accattivante per il potenziamento della memoria nelle…

Combined HACCP and TOPSIS-based approach to prioritize risks in the salmon manufacturing process: A case study

The food safety risk assessment is defined by the Codex Alimentarius Commission as the scientific evaluation of known or potential adverse health effects resulting from human exposure to food-borne hazards. Nowadays, the implementation of a systematic and disciplined risk assessment approach in the food safety field is recognized to be a powerful tool for carrying out science-based analyses and for reaching sound consistent solutions to food safety problems. With this recognition, a combined Hazard Analysis and Critical Control Point (HACCP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS)-based approach is proposed in the present paper to prioritize risks of t…

Alternatives to the traditional waste management: Food recovery for human non-profit organizations

Food supply chains are affected by losses of products which become poorly attractive for the consumers as they get close to their expiration date, therefore remaining unsold on the shelves. Such situation is ethically depreciable considering that many undernourished people rely on non-profit organizations for their survival. Despite of this situation, food recovery through the supply chain is still scarcely practiced, and the potential benefits achievable are frequently ignored. The paper presents a mathematical model for the coordination of the supply chain operating a food recovery policy. The model determines the optimal time for withdrawing the products from the shelves and the quantity…

Ranking of shelf life models based on smart logistic unit using the ELECTRE III method

The aim of this paper is the evaluation of Shelf Life (SL) models based on Smart logistic unit to support the management of the food supply chain in order to guarantee the shelf life of products in agreement with logistic efficiency and system sustainability. For this purpose, the main shelf life equations based on parameters that influence the quality of perishable products were defined and the correspondent acquiring and gathered system has been developed. The selection of the optimal SL model was carried out by means of the multi-criteria decision-making procedure ELECTRE III.

Human reliability analysis to support the development of a software project

The Human Reliability Analysis (HRA) is considered as a useful tool in predicting and quantifying the occurrence of human errors during the execution of a specific task. With this recognition, the present paper firstly aims at discussing the support given by HRA methodologies to the fault risk evaluation. Then, the Technique for Human Error Rate Prediction (THERP) is suggested to evaluate the success probability of a software development project.

A Multi-Criteria Group Decision To Support The Maintenance Service: A Case Study

The present paper wants to propose a methodology to support a group of decision makers into the choice of actions, to implement on a multi-component system, regarding the maintenance service. The choice has to be made on the basis of several criteria, namely the total maintenance cost, the system unavailability and by considering the maintenance actions feasibility. In particular, with the aim to select the maintenance service that represents for the group the best comprise among the criteria to satisfy, the proposed methodology consists of two multi-criteria decisions methods to apply in two successive phases. The first one regards the application of the Analytic Hierarchy Process (AHP) to…

A multi-decision makers approach to select the maintenance plan for a multi-component system.

Damage to Strawberries Caused by Simulated Transport

The quality and condition of perishable products delivered to the market and their subsequent selling prices are directly affected by the care taken during harvesting and handling. Mechanical injury, in fact, occurs at all stages, from pre-harvest operations through post-harvest handling, packing and transport to the market. The main implications of this damage are the reduction of the product’s quality and economical losses related to the shelf life diminution. For most perishable products, the shelf life is relatively short and it is typically dictated by microbial growth related to the application of dynamic and static loads during transportation. This paper presents the correlation betw…

INEMOTION - EMOTIONAL INTELLIGENCE: EDUCATIONAL TOOL FOR DEVELOPING KEY COMPETENCES

Modern societies of the 21st century are immersed in a growing complexity that implies great development and opportunities, but also certain costs and difficulties. Different studies that evaluate and compare the quality of life of both adults and children in different dimensions indicate that economic development, wealth and GDP are not always accompanied by similar levels of well-being and happiness. For example, a country like the United States with impressive levels of wealth and technological development has one of the lowest wellbeing rates in developed countries. Europe is not exempt from these contradictions and the population suffers serious physical and mental health problems, as …
