Estimación del valor económico de la calidad del agua de un río mediante una doble aproximación: una aplicación de los principios económicos de la Di…
2011
El principal objetivo de la Directiva Marco del Agua de la Unión Europea es logar un “buen estado†de las aguas europeas para el año 2015 mediante una combinación de diferentes medidas. En este estudio, dos métodos de preferencias declaradas, el método de valoración contingente y el método de ordenación contingente, han sido aplicados para obtener la valoración económica de una hipotética mejora de la calidad del agua de un río. La comparación de las dos metodologías muestra que las valoraciones obtenidas con el método de ordenación contingente son considerablemente mayores que las obtenidas con la valoración contingente. Por último, los valores estimados se agregan para obtener una apro…
The Perpetrator's mise-en-scene: Language, Body, and Memory in the Cambodian Genocide
2018
Rithy Panh's film S-21. The Khmer Rouge Killing Machine (2003) was the result of a three-year shooting period in the Khmer Rouge centre of torture where perpetrators and victims exchanged experiences and re-enacted scenes from the past under the gaze of the filmmaker's camera. Yet, a crucial testimony was missing in that puzzle: the voice of the prison's director, Kaing Guek Eav, comrade Duch. When the Extraordinary Chambers in the Courts of Cambodia (ECCC) were finally established in Phnom Penh to judge the master criminals of Democratic Kampuchea, the first to be indicted was this desk criminal. The film Duch, Master of the Forges of Hell (R. Panh, 2011) deploys a new confrontation – an a…
The effect of the axial heat transfer on space charge accumulation phenomena in HVDC cables
2020
To date, it has been widespread accepted that the presence of space charge within the dielectric of high voltage direct current (HVDC) cables is one of the most relevant issues that limits the growing diffusion of this technology and its use at higher voltages. One of the reasons that leads to the establishment of space charge within the insulation of cables is the temperature dependence of its conductivity. Many researchers have demonstrated that high temperature drop over the insulation layer can lead to the reversal of the electric field profile. In certain conditions, this can over-stress the insulation during polarity reversal (PR) and transient over voltages (TOV) events accelerating …
An Adaptive Alternating Direction Method of Multipliers
2021
AbstractThe alternating direction method of multipliers (ADMM) is a powerful splitting algorithm for linearly constrained convex optimization problems. In view of its popularity and applicability, a growing attention is drawn toward the ADMM in nonconvex settings. Recent studies of minimization problems for nonconvex functions include various combinations of assumptions on the objective function including, in particular, a Lipschitz gradient assumption. We consider the case where the objective is the sum of a strongly convex function and a weakly convex function. To this end, we present and study an adaptive version of the ADMM which incorporates generalized notions of convexity and penalty…
Dust mobilization due to density currents in the Atlas region: Observations from the Saharan Mineral Dust Experiment 2006 field campaign
2007
[1] Evaporation of precipitation is a ubiquitous feature of dry and hot desert environments. The resulting cooling often generates density currents with strong turbulent winds along their leading edges, which can mobilize large amounts of dust. Mountains support this process by triggering convection, by downslope acceleration of the cool air, and by fostering the accumulation of fine-grained sediments along their foothills through the action of water. For the Sahara, the world's largest dust source, this mechanism has been little studied because of the lack of sufficiently high resolution observational data. The present study demonstrates the frequent occurrence of density currents along th…
La suspensión de la libre circulación de inversiones extranjeras en España por la crisis del COVID-19 (The Suspension of the Free Movement of Foreign…
2020
Spanish Abstract: La libre circulacion de inversiones es uno de los mantras que ha caracterizado la modernidad economica. El principio, sin embargo, se encuentra sometido a creciente prevencion, en el marco de una vision critica hacia la globalizacion en un mundo en pleno reajuste geoestrategico. Una de las manifestaciones de esta tendencia reciente de empoderamiento del Estado se refleja en la articulacion de mecanismos de control de las inversiones foraneas que le permitan evitar que sectores claves de la economia nacional caigan en manos de inversores extranjeros, en muchas ocasiones, controlados por Estados competidores. A diferencia de lo que ocurre con los paises de nuestro entorno, E…
COVID-19 y libre circulación de inversiones: un (muy) difícil matrimonio (COVID-19 and Free Movement of Investment: A (Very) Difficult Marriage)
2020
Spanish Abstract: Las inversiones extranjeras estan siendo objeto de una aproximacion mas cautelosa y critica en los ultimos anos en gran numero de paises. Una posicion que se refleja en su regimen juridico y se manifiesta, entre otros extremos, en el diseno de mecanismos de control previo con base en su eventual contrariedad con la seguridad nacional del pais receptor. La pandemia del COVID-19 no ha hecho sino acentuar esta tendencia. La posicion mantenida por la UE al respecto, y la suspension de la libre circulacion de inversiones decidida por el Gobierno espanol son manifestaciones de ello que, todo apunta, han venido para perdurar. English Abstract: In recent years, foreign investment …
Corporate governance and performance: An analysis of Italian listed companies
2020
In recent years, both corporate governance and performance management have been subjected to considerable changes. In this dynamic context, it is interesting to study the evolution of the relationship between performance and governance. Does governance still affect performance? The purpose of this paper is to verify the presence and intensity (extent) of the relationship between corporate governance and performance in Italian listed companies by using both accounting and non-accounting performance measures. The purpose of this paper is to investigate the effects of prior firm performance on board composition and governance structure of some companies listed on the Italian stock exchange, an…
Les effets des liens personnels interconseils sur la performance de l'entreprise : une analyse comparée entre France et Allemagne
2010
Obgleich das Thema „personelle Unternehmensverflechtungen über den Aufsichtsrat“ re-gelmäßig im Fokus öffentlicher Diskussionen steht – wobei in der Regel eine negative Wirkung der Mandatekumulation auf die Kontrolleffizienz des Überwachungsgremiums und damit letztlich auf die Unternehmensperformance unterstellt wird –, zeigt eine Analyse der empirischen Litera-tur, dass insbesondere in Kontinentaleuropa eine klare Schlussfolgerung hinsichtlich der Wirkung von Mehrfachmandaten auf die Wertschöpfung für die Aktionäre nicht möglich ist. Ursache für die starke Divergenz der Ergebnisse scheint sowohl die Verwendung verschiedener theoretischer Erklärungsmodelle als auch die Mobilisierung untersc…
Impact of a stay in the intensive care unit on the preparation of Advance Directives: Descriptive, exploratory, qualitative study.
2017
Abstract Background Our objective was to assess, through a qualitative, exploratory study, the thought processes of patients regarding the formulation of advance directives (AD) after a stay in the ICU. Methods The study was conducted from May to July 2016 using telephone interviews performed by four senior ICU physicians. Inclusion criteria were: patients discharged from ICU to home > 3 months earlier. Semi-directive interviews with patients focused on 5 main points surrounding AD. Results In total, among 159 eligible patients, data from 94 (59%) were available for analysis. Among all those interviewed, 83.5% had never heard of “advance directives”. Only 2% had executed AD before ICU admis…
