A strategic approach for the discounted Shapley values

2014

The family of discounted Shapley values is analyzed for cooperative games in coalitional form. We consider the bargaining protocol of the alternating random proposer introduced in Hart and Mas-Colell (Econometrica 64:357–380, 1996). We demonstrate that the discounted Shapley values arise as the expected payoffs associated with the bargaining equilibria when a time discount factor is considered. In a second model, we replace the time cost with the probability that the game ends without agreements. This model also implements these values in transferable utility games, moreover, the model implements the \(\alpha \)-consistent values in the nontransferable utility setting.

Dealing with risk: Gender, stakes, and probability effects

2015

This paper investigates how subjects deal with financial risk, both "upside" (with a small chance of a high payoff) and "downside" (with a small chance of a low payoff). We find that the same people who avoid risk in the downside setting tend to make more risky choices in the upside one. The experiment is designed to disentangle the probability-weighting and utility-curvature components of risk attitudes, and to differentiate settings in which gender differences arise from those in which they do not. Women are more risk averse for downside risks, but gender differences are diminished for upside risks.

Economía social y sector no lucrativo: Actualidad científica y perspectivas

2001

In this paper, we intend to analyze some scientific questions of current importance in the Social Economy field and Non-profit sector. In the first place, we show the growing economical importance of this field in Europe, based on the results obtained in the last transnational study. Secondly, we try to think about the concept of non-profit as well as about the position of co-operatives and associations within the Non-profit sector, introducing some criteria of analysis. Immediately after, we study this economical field under a “social” point of view. Finally, the paper analyses the place and content of Social Economy, both business and non-profit sectors, within the limits of European publ…

Indulto y Poder Judicial: ¿Un instrumento para la realización de la Justicia?

2017

El indulto no es un vestigio histórico. su reconocimiento en la totalidad de los textos constitucionales de nuestra historia, advierte la existencia de una necesidad que es satisfecha por el indulto, con independencia del momento en el que se haya aplicado. el indulto ex- presa el desajuste entre la norma penal y la justicia, que solo puede tener su remedio con el otorgamiento de la gracia. Pero la admisibilidad del indulto exige el pleno so- metimiento a la ley y al principio de legalidad, desde un ejercicio restrictivo y excepcional, por tratarse de una potestad extraordinaria, pues determina una alteración de los principios constitucionales. y sólo en la medida que sea el Poder Judicial …

Dying to Save Lives: Zell Kravinsky, Peter Singer, and Lethal Organ Donation

2018

In 2003, after disbursing the bulk of his accumulated fortune of forty-five million dollars to various charities, Zell Kravinsky made the even greater altruistic decision to donate one of his kidneys to a complete stranger. In doing so he incurred the wrath of many in the psychiatric and health professions who questioned his sanity. In response, Kravinsky argued that refusal to donate would have constituted a violation of his belief in “maximum human utility” – a philosophical concept that insists we give up as much as we can for the good of others. Kravinsky has since stated that he would undergo a lethal organ donation in order to save a greater number of people from death, or to save peo…

Kaempferol as a dietary anti-inflammatory agent: current therapeutic standing

2020

Inflammation is a physiological response to different pathological, cellular or vascular damages due to physical, chemical or mechanical trauma. It is characterized by pain, redness, heat and swelling. Current natural drugs are carefully chosen as a novel therapeutic strategy for the management of inflammatory diseases. Different phytochemical constituents are present in natural products. These phytochemicals have high efficacy both in vivo and in vitro. Among them, flavonoids occur in many foods, vegetables and herbal medicines and are considered as the most active constituent, having the ability to attenuate inflammation. Kaempferol is a polyphenol that is richly found in fruits, vegetabl…

2020

(1) Background: Assessments of intervertebral disc (IVD) changes, and IVD tissue adaptations due to physical activity, for example, remains challenging. Newer magnetic resonance imaging techniques can quantify detailed features of the IVD, where T2-mapping and T2-weighted (T2w) and Dixon imaging are potential candidates. Yet, their relative utility has not been examined. The performances of these techniques were investigated to characterize IVD differences in asymptomatic individuals with distinct physical activity histories. (2) Methods: In total, 101 participants (54 women) aged 25–35 years with distinct physical activity histories but without histories of spinal disease were included. T1…

Random utility approach to re-design passengers interchange nodes

2009

The passengers interchange node is a complex infrastructure, where the user can choose among different modal options to do his/her trip. These transport infrastructures have various terminals (car park, bus stop, metro, light rail, railway, extra-urban and sub urban bus and so on). The passengers, inside interchange node, have to reach these terminals walking often with luggage and for long distances. We calibrated a discrete choice model taking into account attributes able to explain the passenger behaviour by observed flows and generalized least squares technique. Furthermore an ex ante / ex post analysis was carried out in order to design and evaluate measure to incentive modal integrati…

Thèse : L'intégration de l'environnement au droit de l'électricité. Vers le renouvellement d'un service public.

2012

Equality, continuity and adaptability. Foundations of the right of the public utilities, Rolland laws apply vigorously to the public service for electricity, where activities did not change since the advent of the « electricity fairy ». It is always about producing, transporting, distributing and supplying electricity, respecting the general interest. Nevertheless, the legal framework applicable to these activities is under a dramatic transition, stemming from the will of the European Union to create a single market for electricity. These changes incrementally drive to a shift of the public utility, basically socially oriented, to more and more demanding and diversified economic objectives.…

Problem Transformation Methods with Distance-Based Learning for Multi-Target Regression

2020

Multi-target regression is a special subset of supervised machine learning problems. Problem transformation methods are used in the field to improve the performance of basic methods. The purpose of this article is to test the use of recently popularized distance-based methods, the minimal learning machine (MLM) and the extreme minimal learning machine (EMLM), in problem transformation. The main advantage of the full data variants of these methods is the lack of any meta-parameter. The experimental results for the MLM and EMLM show promising potential, emphasizing the utility of the problem transformation especially with the EMLM. peerReviewed
