Integración de políticas medio ambientales: Transformaciones institucionales en España

La Integración de la Políticas Ambientales (IPA) consiste en la incorporación de los objetivos ambientales en todos los estadios de elaboración e implementación de las políticas no ambientales (o sectoriales), con un reconocimiento específico de dicho objetivo como principio director de la programación y la puesta en práctica. Se complementa con la previsión de las consecuencias ambientales mediante una evaluación de conjunto de la política con objeto de minimizar las contradicciones entre las políticas ambientales y no ambientales dando prioridad a las primeras. La naturaleza transversal de la IPA no se ajusta a la forma tradicional de gobernanza jerárquica basada en la autoridad del Estado, la diferenciación sectorial, y los instrumentos típicos de dirección y control. Por ello, no es extraño que la IPA se encuentre a menudo asociada a los llamados "nuevos modos de gobernanza". Esta tesis propone analizar empíricamente el estado de la cuestión en España con respecto a la Integración de la política ambiental , tanto a nivel estatal como autonómico (Cataluña, País Vasco), yendo más allá de los compromisos políticos a favor de un mayor grado de integración de los factores ambientales en las demás políticas. En particular, los ámbitos de investigación seleccionados para esta finalidad son el de las políticas de mitigación de las causas y los efectos del cambio climático, y las políticas de desarrollo sostenible. En términos de ‘variable independiente’ La hipótesis que se quiere comprobar es que la acción llevada a cabo por la Unión Europea ha generado profundos cambios en las estructuras de las instituciones mencionadas y en los procesos de elaboración y implementación de determinadas políticas (energía y transporte) así como en las relaciones entre sectores de la administración pública y entre el sector público y el privado.

In vivo measurement of tissue oxygenation by time-resolved luminescence spectroscopy: advantageous properties of dichlorotris(1, 10-phenanthroline)-ruthenium(II) hydrate.

Measuring tissue oxygenation in vivo is of interest in fundamental biological as well as medical applications. One minimally invasive approach to assess the oxygen partial pressure in tissue (pO2) is to measure the oxygen-dependent luminescence lifetime of molecular probes. The relation between tissue pO2 and the probes' luminescence lifetime is governed by the Stern-Volmer equation. Unfortunately, virtually all oxygen-sensitive probes based on this principle induce some degree of phototoxicity. For that reason, we studied the oxygen sensitivity and phototoxicity of dichlorotris(1, 10-phenanthroline)-ruthenium(II) hydrate [Ru(Phen)] using a dedicated optical fiber-based, time-resolved spectrometer in the chicken embryo chorioallantoic membrane. We demonstrated that, after intravenous injection, Ru(Phen)'s luminescence lifetime presents an easily detectable pO2 dependence at a low drug dose (1 mg∕kg) and low fluence (120 mJ∕cm2 at 470 nm). The phototoxic threshold was found to be at 10 J∕cm2 with the same wavelength and drug dose, i.e., about two orders of magnitude larger than the fluence necessary to perform a pO2 measurement. Finally, an illustrative application of this pO2 measurement approach in a hypoxic tumor environment is presented.

Sintonización dinámica de aplicaciones MPI

En la actualidad, la computación de altas prestaciones está siendo utilizada en multitud de campos científicos donde los distintos problemas estudiados se resuelven mediante aplicaciones paralelas/distribuidas. Estas aplicaciones requieren gran capacidad de cómputo, bien sea por la complejidad de los problemas o por la necesidad de solventar situaciones en tiempo real. Por lo tanto se debe aprovechar los recursos y altas capacidades computacionales de los sistemas paralelos en los que se ejecutan estas aplicaciones con el fin de obtener un buen rendimiento. Sin embargo, lograr este rendimiento en una aplicación ejecutándose en un sistema es una dura tarea que requiere un alto grado de experiencia, especialmente cuando se trata de aplicaciones que presentan un comportamiento dinámico o cuando se usan sistemas heterogéneos. En estos casos actualmente se plantea realizar una mejora de rendimiento automática y dinámica de las aplicaciones como mejor enfoque para el análisis del rendimiento. El presente trabajo de investigación se sitúa dentro de este ámbito de estudio y su objetivo principal es sintonizar dinámicamente mediante MATE (Monitoring, Analysis and Tuning Environment) una aplicación MPI empleada en computación de altas prestaciones que siga un paradigma Master/Worker. Las técnicas de sintonización integradas en MATE han sido desarrolladas a partir del estudio de un modelo de rendimiento que refleja los cuellos de botella propios de aplicaciones situadas bajo un paradigma Master/Worker: balanceo de carga y número de workers. La ejecución de la aplicación elegida bajo el control dinámico de MATE y de la estrategia de sintonización implementada ha permitido observar la adaptación del comportamiento de dicha aplicación a las condiciones actuales del sistema donde se ejecuta, obteniendo así una mejora de su rendimiento.

Inter-American Court, Crimes Against Humanity and Peacebuilding in South America

The present work contains a general overview of the sentences of the Inter-American Court of Human Rights (IACtHR), which have recognised that crimes against humanity are pre-existing in customary law, and do not prescribe, nor can they be subject to amnesty or pardon. Specific attention is paid to the consequent restrictions and opportunities offered by said verdicts to countries such as Argentina, Chile, Uruguay and Peru, which find themselves in postconflict transition processes and where peace has been negotiated with certain groups and state structures that are responsible for carrying out crimes against humanity. In doing so, special attention is paid to the impact of the recognition of the nature of crimes against humanity on the notion of the principle of legality, stricto sensu; on the development and evolution of the doctrine and the practice of international human rights law in the inter-American context; and finally on the aforementioned processes of transitional justice.

Disseny, modelat i fabricació d'una antena "trap" per aplicacions WLAN

En aquest treball s’ha dissenyat i fabricat una antena monopol en estructura planar capaç de treballar correctament a les freqüències WLAN de 2,45-2,5 GHz (802.11b/g) i 4,9-5,875 GHz (802.11a/h/j). Per arribar a aquest objectiu primer s’ha presentat el model de línia de transmissió acabada en circuit obert per simular el comportament d’una antena. S’han comparat i verificat els resultats amb el model d’antena de fil. Seguidament, s’ha estudiat el comportament que introdueix el fet de carregar l’antena amb un ressonador LC. Finalment, s’ha passat del model d’antena de fil a una estructura planar. Aquesta geometria ha permès la realització del trap LC de forma distribuïda a través d’un ressonador CLL. El principi de disseny de l’antena està basat en la introducció d’aquest ressonador CLL amb freqüència de ressonància situada entre les dos bandes de treball i que junt amb l’ajust dels diversos paràmetres que defineixen l’antena han permès obtenir més 1 GHz d’ample de banda a la freqüència de 5 GHz.

Scepticism Revisited

Liberalism claims that for a subject S to be justified in believing p, a proposition about the external world, on the basis of his senses it is not necessary to be antecedently justified in believing propositions as there is an external world. On the other hand, conservatism claims that to be justified in believing that p on the basis of one’s perception, one must have antecedent justification to believe that p. Intuitively, we are inclined to think that liberalism about the structure of perceptual justification fits better with our epistemic practices. We acknowledge that, although we cannot produce warrant for the background belief in the external world, our empirical beliefs can be perceptually justified. However, I am interested in arguing that conservatism is theoretically better supported than liberalism. The first reason to defend this is based on the fact that in embracing liberalism dogmatism is affected by pervasive problems. The second one comes from recognizing the strength of the argument based on the thesis that experience is theory-laden. But not all are advantages for conservatism. Conservatism is presupposed in contemporary formulations of scepticism through the requirement of prior justification for background assumptions, and this fact compels anti-sceptical conservatives to conceive a non-evidential form of warrant, entitlement, to contest the sceptical threat My main worry is that, although the path of entitlement has some prospects to succeed, this new notion of justification seems to be posed ad hoc for conservatives to solve the sceptical problem. These contents are organized along the three chapters. The result of chapter 1 is a pattern of sceptical argument formed by two premises: P1*, a conservative principle, and P2*. In chapter 2 and chapter 3 two anti-sceptical proposals against the argument sketched in chapter 1 are described. Chapter 2 is devoted to explain and assess a first anti-sceptical proposal that denies P1*: dogmatism. Moreover, in chapter 3, another anti-sceptical strategy is described (the route of entitlement) that contests scepticism denying the plausibility of P2*.

La ironía en el transfer intercultural : aproximación pragmática en la traducción al castellano de relatos satíricos de Mijaíl Zoschenko y Mijaíl Bulgákov

El presente estudio está dedicado a analizar la traducción de la ironía en una obra de ficción literaria, más concretamente en los relatos satíricos de Mijaíl Zoschenko y Mijaíl Bulgákov en su versión castellana. Metodológicamente, el estudio presenta un enfoque pragmático, y se inscribe en las aportaciones pragmáticas de la segunda mitad del siglo XX, que permiten analizar el texto literario como un acto de comunicación y un discurso dialógico, inscribiéndolo en un contexto extralingúístico relevante. Abordaremos el análisis de lo "no dicho": el subtexto irónico que subyace como un significado implícito no-deducible de los medios lingüísticos en sí mismos, y donde cobran una gran importancia los factores comunicativos: la situación, la intención del hablante, el principio cooperativo (según Paul Grice) y toda una serie de presupuestos que pueden o no compartir los interlocutores. Partiendo del supuesto de la existencia de diferentes tipos textuales en toda traducción, la ficción literaria se abordará como un tipo de texto que presenta características particupares. En este sentido, el relato satírico de la época soviética se contempla como un género específico que implica, a su vez, una estrategia específica de traducción. Como es sabido, en los textos humorísticos predomina el efecto perlocutivo. Así pues, dependerá del tradutor que el texto transferido a otra cultura, y a menudo a otra época, consiga el mismo efecto humorístico, o similar, al que tuvo el original en su contexto histórico-cultural.

Questioning the utility of RNA-DNA chimera in gene repair.

In principle, we should be glad that Eric Kmiec and his colleagues published in Science's STKE (1) a detailed experimental protocol of their gene repair method (2, 3). However, a careful reading of their contribution raises more doubts about the method. The research published in Science five years ago by Kmiec and his colleagues was said to demonstrate that chimeric RNA-DNA oligonucleotides could correct the mutation responsible for sickle cell anemia with 50% efficiency (4). Such a remarkable result prompted many laboratories to attempt to replicate the research or utilize the method on their own systems. However, if the method worked at all, which it rarely did, the achieved efficiency was usually lower by several orders of magnitude. Now, in the Science's STKE protocol, we are given crucial information about the method and why it is so important to utilize these expensive chimeric RNA-DNA constructs. In the introduction we are told that the RNA-DNA duplex is more stable than a DNA-DNA duplex and so extends the half-life of the complexes formed between the targeted DNA and the chimeric RNA-DNA oligonucleotides. This logical explanation, however, conflicts with the statement in the section entitled "Transfection with Oligonucleotides and Plasmid DNA" that Kmiec and colleagues have recently demonstrated that classical single-stranded DNA oligonucleotides with a few protective phosphothioate linkages have a "gene repair conversion frequency rivaling that of the RNA/DNA chimera". Indeed, the research cited for that result actually states that single-stranded DNA oligonucleotides are in fact several-fold more efficient (3.7-fold) than the RNA-DNA chimeric constructs (5). If that is the case, it raises the question of why Kmiec and colleagues emphasize the importance of the RNA in their original chimeric constructs. Their own new results show that modified single-stranded DNA oligonucleotides are more effective than the expensive RNA-DNA hybrids. Moreover, the current efficiency of the gene repair by RNA-DNA hybrids, according to Kmiec and colleagues in their recent paper is only 4×10-4 even after several hours of pre-selection permitting multiplification of bacterial cells with the corrected plasmid (5). This efficiency is much lower than the 50% value reported five years ago, but is assuredly much closer to the reality.

Clínica jurídica ambiental

La “Clínica Jurídica Ambiental” constitueix una experiència d’innovació docent desenvolupada en el marc del Màster Oficial en Dret Ambiental i de la Llicenciatura en Dret de la Universitat Rovira i Virgili des del curs 2005-2006. El mètode clínic, que parteix dels principis de la contextualització de l’aprenentatge en escenaris reals, el model de learning by doing i la redefinició dels rols de l’alumne i del professor en el procés d’ensenyament-aprenentatge, és una estratègia que permet a l’alumne una formació integral orientada a la capacitació professional, d’acord amb el canvi de paradigma educatiu que suposa la creació de l’EEES. Es pretén així assolir una millor qualitat dels titulats a partir d’una formació en competències genèriques i específiques assolibles només amb estratègies d’aprenentatge actiu que facilitin l’autonomia i la responsabilització en la construcció del propi aprenentatge. Paral·lelament, la metodologia obliga a establir mecanismes de coordinació entre el professorat de diverses àrees de coneixement jurídiques. Els alumnes treballen en petits grups, durant el curs acadèmic, sobre un cas real subministrat per un client extern (administracions públiques, fiscalia, ONG,s). Els alumnes tenen un tutor intern, professor, i un tutor extern, que pertany a la institució que ha subministrat el cas. El tutor intern avalua de manera contínua i individual el procés d’aprenentatge de l’alumne (60% de la qualificació final); l'extern avalua el resultat final (40 % de la qualificació final), que s’ha de presentar com a treball de grup quan finalitza el curs acadèmic. El finançament atorgat per l’AGAUR, en el marc de la convocatòria MQD 2006, ha permès introduir millores significatives en aquest projecte: la introducció de la figura dels practitioners (advocats en exercici) en l’equip docent; l’organització d’un Seminari Internacional sobre Clinical Legal Education, i la realització de sessions plenàries formatives pels professors i els alumnes de la Clínica.

Decentralization, happiness and the perception of institutions

This paper analyses whether the different powers and resources at the disposal of local and regional governments across Europe deliver greater satisfaction with political institutions and lead to greater personal happiness. The analysis uses microdata from the four available waves of the European social survey (2002, 2004, 2006 and 2008), including more than 160,000 observations of individuals living in 29 European countries. Our results reveal that political and fiscal decentralization have a positive and significant effect on individuals’ overall happiness. Fiscal decentralization also exerts a significant effect on the level of satisfaction with political and economic institutions and with the education and health systems, whereas the effect of political decentralization on these variables is more limited. The results show that citizens seem to be happier with the actual capacity of their local governments to deliver than with the general principle that they can have a say on their daily politics and policies.

Local and global consistency properties for student placement

In the context of resource allocation on the basis of priorities, Ergin (2002) identifies a necessary and sufficient condition on the priority structure such that the student-optimal stable mechanism satisfies a consistency principle. Ergin (2002) formulates consistency as a local property based on a fixed population of agents and fixed resources -- we refer to this condition as local consistency and to his condition on the priority structure as local acyclicity. We identify a related but stronger necessary and sufficient condition (unit acyclicity) on the priority structure such that the student-optimal stable mechanism satisfies a more standard global consistency property. Next, we provide necessary and sufficient conditions for the student-optimal stable mechanism to satisfy converse consistency principles. We identify a necessary and sufficient condition (local shift-freeness) on the priority structure such that the student-optimal stable mechanism satisfies local converse consistency. Interestingly, local acyclicity implies local shift-freeness and hence the student-optimal stable mechanism more frequently satisfies local converse consistency than local consistency. Finally, in order for the student-optimal stable mechanism to be globally conversely consistent, one again has to impose unit acyclicity on the priority structure. Hence, unit acyclicity is a necessary and sufficient condition on the priority structure for the student-optimal stable mechanism to satisfy global consistency or global converse consistency.

A never-ending debate: Demand versus supply water policies. A CGE analysis for Catalonia

Water scarcity is a long-standing problem in Catalonia, as there are significant differences in the spatial and temporal distribution of water through the territory. There has consequently been a debate for many years about whether the solution to water scarcity must be considered in terms of efficiency or equity, the role that the public sector must play and the role that market-based instruments should play in water management. The aim of this paper is to use a Computable General Equilibrium (CGE) model to analyze the advantages and disadvantages associated with different policy instruments, from both a supply and a demand viewpoint, which can be applied to water management in Catalonia. We also introduce an ecological sector in our CGE model, allowing us to analyze the environmental impact of the alternative policies simulated. The calibration of the exogenous variables of the CGE model is performed by using a Social Accounting Matrix (SAM) for the Catalan economy with 2001 data. The results suggest that taking into account the principle of sustainability of the resource, the policy debate between supply and demand in water policies is obsolete, and a new combination of policies is required to respect the different values associated with water.

Schistosomiasis vaccine development: progress and prospects

The undisputed, worldwide success of chemotherapy notwithstanding, schistosomiasis continues to defy control efforts in as much rapid reinfection demands repeated treatment, sometimes as often as once a year. There is thus a need for a complementary tool with effect for the longer term, notably a vaccine. International efforts in this direction have been ongoing for several decades but, until the recombinant DNA techniques were introduced, antigen production remained an unsurmountable bottleneck. Although animal experiments have been highly productive and are still much needed, they probably do not reflect the human situation adequately and real progress can not be expected until more is known about human immune responses to schistosome infection. It is well-known that irradiated cercariae consistently produce high levels of protection in experimental animals but, for various reasons, this proof of principle cannot be directly exploited. Research has instead been focussed on the identification and testing of specific schistosome antigens. This work has been quite successful and is already at the stage where clinical trials are called for. Preliminary results from coordinated in vitro laboratory and field epidemiological studies regarding the protective potential of several antigens support the initiation of such trials. A series of meetings, organized earlier this year in Cairo, Egypt, reviewed recent progress, selecteded suitable vaccine candidates and made firm recommendations for future action including pledging support for large-scale production according to good manufacturing practice (GMP) and Phase I trials. Scientists at the American Centers for Disease Control and Prevention (CDC) have drawn up a detailed research plan. The major financial support will come from USAID, Cairo, which has established a scientific advisory group of Egyptian scientists and representatives from current and previous international donors such as WHO, NIAID, the European Union and the Edna McConnell Clark Foundation.

Consensus summary statement of the International Multidisciplinary Consensus Conference on Multimodality Monitoring in Neurocritical Care : A statement for healthcare professionals from the Neurocritical Care Society and the European Society of Intensive Care Medicine.

Neurocritical care depends, in part, on careful patient monitoring but as yet there are little data on what processes are the most important to monitor, how these should be monitored, and whether monitoring these processes is cost-effective and impacts outcome. At the same time, bioinformatics is a rapidly emerging field in critical care but as yet there is little agreement or standardization on what information is important and how it should be displayed and analyzed. The Neurocritical Care Society in collaboration with the European Society of Intensive Care Medicine, the Society for Critical Care Medicine, and the Latin America Brain Injury Consortium organized an international, multidisciplinary consensus conference to begin to address these needs. International experts from neurosurgery, neurocritical care, neurology, critical care, neuroanesthesiology, nursing, pharmacy, and informatics were recruited on the basis of their research, publication record, and expertise. They undertook a systematic literature review to develop recommendations about specific topics on physiologic processes important to the care of patients with disorders that require neurocritical care. This review does not make recommendations about treatment, imaging, and intraoperative monitoring. A multidisciplinary jury, selected for their expertise in clinical investigation and development of practice guidelines, guided this process. The GRADE system was used to develop recommendations based on literature review, discussion, integrating the literature with the participants' collective experience, and critical review by an impartial jury. Emphasis was placed on the principle that recommendations should be based on both data quality and on trade-offs and translation into clinical practice. Strong consideration was given to providing pragmatic guidance and recommendations for bedside neuromonitoring, even in the absence of high quality data.
