A stochastic interspecific competition model to predict the behaviour of Listeria monocytogenes in the fermentation process of a traditional Sicilian…

2008

The present paper discusses the use of modified Lotka-Volterra equations in order to stochastically simulate the behaviour of Listeria monocytogenes and Lactic Acid Bacteria (LAB) during the fermentation period (168 h) of a typical Sicilian salami. For this purpose, the differential equation system is set considering T, pH and aw as stochastic variables. Each of them is governed by dynamics that involve a deterministic linear decrease as a function of the time t and an "additive noise" term which instantaneously mimics the fluctuations of T, pH and aw. The choice of a suitable parameter accounting for the interaction of LAB on L. monocytogenes as well as the introduction of appropriate nois…

Agricultural and Biotechnology Patents as an Adaptation Strategy to Climate Change: A Regional Analysis of European Farmer’s Efficiency

2022

This chapter analyses the effect of innovation encouraged by climate change challenges on European farmers’ technical efficiency. Using the stochastic frontier approach, we estimate the impact of agri-cultural patents on farmers’ technical efficiency by taking into account both unobservable heterogeneity and heteroscedasticity in the inefficiency term. Our findings suggest that European farmers remain quite far from the maximum frontier and irrespective of the country in which they reside; farmers who innovate are more efficient than those who do not. Thus, the inefficiency of agricultural agents in the European context leaves space for policies that incentivise firms to adopt climate chang…

Some Considerations on the Sustainable Urban Development in Romania

2015

Abstract (Promoting an integrated approach is important for sustainable urban development. Most priorities identified during 2007-2013 were not achieved due to the global financial crisis, but also because of the lack of mature projects concerning regional development. As during the previous period, much development needs remain unresolved, including the level of high pollution in the urban areas, vacant, unused and degraded urban areas corresponding to the cities of Romania, as well as valuable resources of cultural heritage which are poorly capitalized. ROP continues during 2014-2020 with a strategic vision on regional development in Romania, contained in the 2007-2013 National Developmen…

Agro-food markets’ functional efficiency, products’ quality and information’s role

2018

Nowadays agro-food productions’ quality and markets’ economic efficiency are strictly connected and related to the increasing information’s role that is no doubt simplify by the global presence of the World Wide Web system. It is possible to assert that this kind of situation does not always safeguard information’s safety and propriety and at the same time consumers’ aware and complete choice capability. From a production markets’ economic efficiency point of view these elements contribute to create some kind of functional distortions able to prevent their proper working system under the economic theory profile and supply misunderstandings and informational asymmetries. These specific condi…

A multi-objective approach to facility layout problem by genetic search algorithm and Electre method

2006

Abstract Classical approaches to layout design problem tend to maximise the efficiency of layout, measured by the handling cost related to the interdepartmental flow and to the distance among the departments. However, the actual problem involves several conflicting objectives hence requiring a multi-objective formulation. Multi-objective approaches, recently proposed, in most cases lead to the maximisation of a weighted sum of score functions. The poor practicability of such an approach is due to the difficulty of normalising these functions and of quantifying the weights. In this paper, this difficulty is overcome by approaching the problem in two subsequent steps: in the first step, the P…

Towards a Sustainable Use of Architectural Heritage: How to Assess Accessibility and the User’s Role

2022

Scientific communities and institutional bodies are supporting many shared efforts towards improving accessibility to architectural heritage, in the awareness that it provides the basis for inclusion and enhancement. Accessibility is related to the wider tendency toward a conscious and sustainable use of the architectural heritage, considered as a multifaceted tool for its conservation. This has also highlighted the user’s role, which is paramount in order to reach and increase sustainable processes in the field of architectural heritage, as well as in all the technological processes. The user should be active in his/her relationships with the built heritage, in a multi-sensorial way and in…

Fostering sustainable community outcomes through policy networks: a dynamic performance governance approach

2021

This chapter will illustrate how an “outside-in” view of policy making may implement a balanced perspective for assessing sustainable outcomes through an integrated Dynamic Performance Management and Governance framework. In the next sections such a framework will be illustrated and applied to different examples of collaborative networks. In the remaining part of this section practical implications from an “outside-in” view of policy making will be illustrated.

Environmental effects of tourism and its seasonality on Mediterranean islands: the contribution of the Interreg MED BLUEISLANDS project to build up a…

2020

AbstractThe Mediterranean basin is amongst the world’s main tourist destination, and its islands are a major attraction, being sites of historical, cultural and naturalistic importance. This is beneficial for the local economies, but it may also represent a great burden on the coastal environment, where other human pressures are concentrated. The awareness of detrimental side effects of tourism together with the importance to take into account social and economic facets has led to the concept of sustainable tourism, which, however, represents a goal far from being attained. A good opportunity to promote sustainable tourism was provided by the Interreg MED BLUEISLANDS project, whose main aim…
