Standardization of Road Danger Signs in the European Union
2015
The aim of this research is to find a solution for the standardization of road signs in the EU zone by a comparative analysis of different national sign systems to establish a common set from a single country. This work is based on the idea that road sign standardization might increase the safety level of transnational journeys and foster the relationships among the various members of the EU Community. This paper presents the outcome of the first step of the research, which focuses on the harmonization of danger signs. In more detail, a multicriteria approach is applied to rank 19 EU Member States on the basis of three main aspects: the installation cost of new signs, new sign learning issu…
Just transition principles and criteria for food systems and beyond
2022
In this article, we propose a framework of principles and criteria for just transitions in food systems. Climate mitigation activities are urgently needed in food systems, but can have damaging social, environmental, economic, and health impacts. Consequently, food system transitions can cause significant side effects across and beyond food systems, aggravating existing inequalities and unsustainabilities, causing new ones, or hampering equal engagement in the transition itself. Thus, justice questions stand at the core of assessing decarbonization pathways and policies and must link to other sectors as well: Who bears the costs and who enjoys the benefits of the transitions? Can transition…
Corporate responsibility in the food chain: The criteria and indicators
2012
Corporate responsibility (CR) is becoming a key issue in the food chain. In order to make sense of this phenomenon, a seminal aper by Maloni and Brown (2006) called for further empirical investigation on the criteria of responsibility in the food supply chain. The purpose of this paper is to answer the call by identifying the criteria for defining CR and develop indicators for measuring the responsibility performance of the food chain. The study was based on interactive and participatory stakeholder dialogues with diverse experts, corporate representatives and other stakeholders, including non-governmental organizations (NGOs) and governmental bodies. Through an iterative research process w…
La valutazione multicriteriale del saggio di capitalizzazione per la revisione del catasto degli immobili
2012
Il riferimento teorico economico dei procedimenti tradizionali di stima immobiliare è il modello di mercato perfettamente concorrenziale, in cui il valore di un bene può derivarsi dal prezzo di un altro bene analogo, in virtù del principio di sostituzione dei simili e della legge di indifferenza dei prezzi. Nella pratica estimativa, si riscontra una certa difficoltà nell’individuazione di appropriati beni con cui costruire un campione di riferimento per la stima e la mancata corrispondenza fra i prezzi di beni anche identici in contesti di mercato molto ristretti rende più complicato il processo di derivazione del valore di un bene da un altro. La revisione del catasto immobiliare che il go…
Why Use Interactive Multi-Objective Optimization in Chemical Process Design?
2008
Problems in chemical engineering, like most real-world optimization problems, typically, have several conflicting performance criteria or objectives and they often are computationally demanding, which sets special requirements on the optimization methods used. In this chapter, we point out some shortcomings of some widely used basic methods of multi-objective optimization. As an alternative, we suggest using interactive approaches where the role of a decision maker or a designer is emphasized. Interactive multi-objective optimization has been shown to suit well for chemical process design problems because it takes the preferences of the decision maker into account in an iterative manner tha…

El rendimiento académico en función del sistema de evaluación empleado
2012
This paper examines the academic performance depending on the evaluation and rating system used in the university. The sample under study consists of 30 subjects -taught by 35 professors to 2192 students from 7 different degrees at 14 universities of all Spain-. The results confirm that continuous assessment is the one that best results not only in terms of rate of return and success rate but also in terms of grades. En este trabajo se estudia el rendimiento académico en función del sistema de evaluación y calificación empleado en el ámbito universitario. La muestra objeto de estudio está formada por 30 asignaturas -impartidas por 35 profesores a 2192 alumnos de 7 titulaciones diferentes en…
Testing and implementing a new approach to estimating interregional output multipliers using input-output data for South Korean regions
2020
Flegg's location quotient (FLQ) is a useful tool for estimating intraregional output multipliers. This paper uses it as one component when estimating interregional multipliers. Using statistical information criteria and official data for 16 South Korean regions, it is found that the best approach is to combine the FLQ with a simple trade model. The paper explains how the proposed procedure can be implemented for both multiple and individual regions, and also how a region-specific value for the unknown parameter δ in the FLQ formula can be determined. Finally, an illustrative case study of one of the regions is carried out.
The city management: methodological considerations on multriple criteria techniques for the selection and aggregation of criteria
2012
The scientific community recognizes that factors such as “social cohesion”, “social quality”, “social capital” and other have a strategic role in the evaluation of the en-richment or the impoverishment of society which occurs in urban environment. These factors are used to evaluate the quality of a social system and to discriminate between different policy alternatives in the management of the city. Social cohesion, quality, equity, progress, etc. are aggregate indicators of urban quality, as they incorporate various components related to multiple points of view. The scientific community and some national and international institutions have proposed different sets of indicators for the esti…
On the Stability of the Soft Pendulum With Affine Curvature: Open-Loop, Collocated Closed-Loop, and Switching Control
2022
This letter investigates the stability properties of the soft inverted pendulum with affine curvature - a template model for nonlinear control of underactuated soft robots. We look at how changes in physical parameters affect stability and equilibrium. We give conditions under which zero dynamics corresponding to a collocated choice of the output is (locally or globally) stable or unstable. We leverage these results to design a switching controller that stabilizes a class of nonlinear equilibria of the pendulum, which can drive the system from one equilibrium to another.
