We study the problem of dividing a budget among the districts of a city taking into account their population and wealth. We focus on order preservation properties that ensure higher transfers to those districts with larger populations and, at the same time, introduce a policy redistribution so that districts with lower wealth per capita obtain…
In view of the urgency and challenges of mitigating climate change, it should be noted that Greenhouse Gas (GHG) emitted from the supply chains of the 2,500 largest global corporations accounts for about 18% of global GHG emissions. Therefore, rationalizing emissions in supply chains could make a significant contribution to achieving the CO2 emission reduction…
En el análisis de la exclusión social, se ha constatado la importancia de la dimensión trabajo. La persistencia del paro, la temporalidad en el empleo o los bajos salarios, inciden de forma importante sobre los niveles de pobreza y exclusión social. En este trabajo se ha recopilado información sobre distintas variables relacionadas con el mercado…
Optimization problems involving polynomial functions are of great importance in applied mathematics and engineering, and they are intrinsically hard problems. They arise in important engineering applications such as the sensor network localization problem, and provide a rich and fruitful interaction between algebraic-geometric concepts and modern convex programming. In this talk, we will discuss some recent…
Abstract During the last years, interest on hybrid metaheuristics has risen considerably in the field of optimization and machine learning. The best results found for many optimization problems in science and industry are obtained by hybrid optimization algorithms. Combinations of optimization tools such as metaheuristics, mathematical programming, constraint programming and machine learning, have provided very…
Abstract Much biodiversity is found in farm land. However, there is usually a trade-off between farm land productivity and sustainability of natural resources. Biodiversity conservation in agricultural land usually requires to carry on a series of conservationist practices that are costly. Therefore, farmer’s participation in conservationist programs requires economic incentives. Our goal is to identify…
Abstract In the current presentation, I intend to extend the developments in Kruger, Ngai & Théra, SIAM J. Optim. 20(6), 3280-3296 (2010) and, more precisely, to characterize, in the Banach space setting, the stability of the local and global error bound property of inequalities determined by proper lower semicontinuous under data perturbations. I will propose…
Abstract: By using robustness methods we design HCRs that explicitly include scientific uncertainty. Under scientific uncertainty –when the perceived model can be generated by a nearby operating model– robust HCRs are designed assuming that the (inferred) operating model is more persistent than the perceived model. As a result, a robust HCR has a steeper ratio…
Since Esping-Andersen identified different welfare state systems among the European countries in his 1990 work The Three Worlds of Welfare Capitalism, research has been conducted to verify this typology. For instance, Sapir (2005), in his work Globalisation and the Reform of European Social Models, expands the original classification through a simple comparison, identifying four types…
Abstract: La Comisión de Derechos de la Mujer e Igualdad de Género del Parlamento Europeo, en un informe de 2012 sobre la representación de las mujeres en los procesos de decisiones políticas, recomienda reformas en los sistemas electorales para que favorezcan la representación femenina. El mencionado informe reconoce que los sistemas electorales tienen un papel…
