El arteterapia permite una aproximación creativa biográfica particularmente valiosa en la etapa final de la vida. La persona enferma presenta múltiples necesidades – físicas, emocionales, sociales y espirituales – que solo una atención holística puede pretender abarcar, tal como lo contempla la filosofía de los cuidados paliativos. El arteterapeuta integrado en el equipo interdisciplinar contribuye a aliviar y acompañar el sufrimiento del paciente y su familia. Se presentan aquí las bases teóricas y la metodología de la intervención, así como el marco sanitario en el cual se inscribe.

Spinal cord injury (SCI) is a devastating neurological disorder that affects thousands of people each year. Although in recent decades significant progress has been made in relation to understanding the molecular and cellular events underlying the nervous damage, spinal cord injury is still a highly disabling condition for which there is no curative therapy. People affected by spinal cord injuries manifested dysfunction or loss, temporary or permanent, of motor, sensory and / or autonomic functions depending on the spinal lesion damaged. Currently, the incidence rate of this type of injury is approximately 15-40 cases per million people worldwide. At the origin of these lesions are: road accidents, falls, interpersonal violence and the practice of sports. In this work we placed the hypothesis that HA is one of the component of the scar tissue formed after a compressive SCI, that it is likely synthetised by the perilesional glial cells and that it might support the permeation of the glial scar during the late phase of SCI. Nowadays, much focus is drawn on the recovery of CNS function, made impossible after SCI due to the high content of sulfated proteoglycans in the extracellular matrix. Counterbalancing the ratio between these proteoglycans and hyaluronic acid could be one of the experimental therapy to re-permeate the glial scar tissue formed after SCI, making possible axonal regrowth and functional recovery. Therefore, we established a model of spinal cord compression in mice and studied the glial scar tissue, particularly through the characterization of the expression of enzymes related to the metabolism of HA and the subsequent concentration thereof at different distances of the lesion epicenter. Our results show that the lesion induced in mice shows results similar to those produced in human lesions, in terms of histologic similarities and behavioral results. but these animals demonstrate an impressive spontaneous reorganization mechanism of the spinal cord tissue that occurs after injury and allows for partial recovery of the functions of the CNS. As regards the study of the glial scar, changes were recorded at the level of mRNA expression of enzymes metabolizing HA i.e., after injury there was a decreased expression of HA synthases 1-2 (HAS 1-2) and an increase of the expression HAS3 synthase mRNA, as well as the enzymes responsible for the HA catabolism, HYAL 1-2. But the amount of HA measured through the ELISA test was found unchanged after injury, it is not possible to explain this fact only with the change of expression of enzymes. At two weeks and in response to SCI, we found synthesized HA by reactive astrocytes and probably by others like microglial cells as it was advanced by the HA/GFAP+ and HA/IBA1+ cells co-location.

Le but de cette recherche était d'évaluer si une stratégie d'enseignement axée sur les mises en situation, permettrait aux élèves d'électrotechnique de collège II, d'améliorer leur capacité à résoudre des problèmes, tant théoriques que pratiques. Pour vérifier cette hypothèse, nous nous sommes appuyé sur des recherches faites en psychologie cognitive et dans le domaine de la psychologie appliquée à l'entraînement dans le monde du travail. Les sujets qui ont participé à l'expérimentation étaient composés de l’ensemble des élèves qui suivaient le cours d'électronique industrielle portant le numéro 243-370-84. Le protocole expérimental était de type pré-expérimental avec expérimentation réelle. Il prévoyait un prétest théorique et un prétest pratique, une intervention d'une durée de six semaines, et un post-test théorique et pratique. L'intervention s'est faite à l'intérieur des périodes prévues du cours concerné, et comprenait six modules, dont le contenu portait sur les sources à courant continu. Les résultats de cette recherche indiquent qu'il y a eu une amélioration sensible des performances de résolution de problèmes, tant théoriques que pratiques, et permettent de partager le taux de réussite des problèmes de type déclaratif et procédural. Nous croyons que cette stratégie peut améliorer l'acquisition de connaissances, favoriser la création de liens et l'habileté à résoudre des problèmes.

This dissertation contains four essays that all share a common purpose: developing new methodologies to exploit the potential of high-frequency data for the measurement, modeling and forecasting of financial assets volatility and correlations. The first two chapters provide useful tools for univariate applications while the last two chapters develop multivariate methodologies. In chapter 1, we introduce a new class of univariate volatility models named FloGARCH models. FloGARCH models provide a parsimonious joint model for low frequency returns and realized measures, and are sufficiently flexible to capture long memory as well as asymmetries related to leverage effects. We analyze the performances of the models in a realistic numerical study and on the basis of a data set composed of 65 equities. Using more than 10 years of high-frequency transactions, we document significant statistical gains related to the FloGARCH models in terms of in-sample fit, out-of-sample fit and forecasting accuracy compared to classical and Realized GARCH models. In chapter 2, using 12 years of high-frequency transactions for 55 U.S. stocks, we argue that combining low-frequency exogenous economic indicators with high-frequency financial data improves the ability of conditionally heteroskedastic models to forecast the volatility of returns, their full multi-step ahead conditional distribution and the multi-period Value-at-Risk. Using a refined version of the Realized LGARCH model allowing for time-varying intercept and implemented with realized kernels, we document that nominal corporate profits and term spreads have strong long-run predictive ability and generate accurate risk measures forecasts over long-horizon. The results are based on several loss functions and tests, including the Model Confidence Set. Chapter 3 is a joint work with David Veredas. We study the class of disentangled realized estimators for the integrated covariance matrix of Brownian semimartingales with finite activity jumps. These estimators separate correlations and volatilities. We analyze different combinations of quantile- and median-based realized volatilities, and four estimators of realized correlations with three synchronization schemes. Their finite sample properties are studied under four data generating processes, in presence, or not, of microstructure noise, and under synchronous and asynchronous trading. The main finding is that the pre-averaged version of disentangled estimators based on Gaussian ranks (for the correlations) and median deviations (for the volatilities) provide a precise, computationally efficient, and easy alternative to measure integrated covariances on the basis of noisy and asynchronous prices. Along these lines, a minimum variance portfolio application shows the superiority of this disentangled realized estimator in terms of numerous performance metrics. Chapter 4 is co-authored with Niels S. Hansen, Asger Lunde and Kasper V. Olesen, all affiliated with CREATES at Aarhus University. We propose to use the Realized Beta GARCH model to exploit the potential of high-frequency data in commodity markets. The model produces high quality forecasts of pairwise correlations between commodities which can be used to construct a composite covariance matrix. We evaluate the quality of this matrix in a portfolio context and compare it to models used in the industry. We demonstrate significant economic gains in a realistic setting including short selling constraints and transaction costs.

This article reports a unique analysis of private engagements by an activist fund. It is based on data made available to us by Hermes, the fund manager owned by the British Telecom Pension Scheme, on engagements with management in companies targeted by its UK Focus Fund. In contrast with most previous studies of activism, we report that the fund executes shareholder activism predominantly through private interventions that would be unobservable in studies purely relying on public information. The fund substantially outperforms benchmarks and we estimate that abnormal returns are largely associated with engagements rather than stock picking. © The Author 2008.

La mise en place du parcours clinique pour les interventions de la prothèse totale ou partielle de la hanche (préalable à la mise en place d'un réseau de soins dans notre étude) présuppose la réalisation des objectifs suivants: - décloisonner le système de santé (en commençant avec les deux acteurs concernés) ; - mettre le patient au coeur du système ; - améliorer l'efficience du système ; - maîtriser les coûts, tout en garantissant une qualité des prestations offertes ; - instaurer une nouvelle coopération et coordination entre fournisseurs de soins, ainsi qu' - accroître les compétences et valoriser les professionnels. C'est un projet de qualité des soins. L'itinéraire est multidisciplinaire et destiné à un groupe bien précis de patients, il repose sur une planification systématique et se traduit par un programme de soins spécifiques. La réalisation de tout ou partie de ces objectifs nous permettra de confirmer ou rejeter l'hypothèse selon laquelle les réseaux de soins sont une possible réponse à la crise actuelle du système de santé. Ces affirmations sont-elles toutes nécessaires à la création d'un réseau de soins ? Sont-elles exclusives ou cumulatives ? Y-a-t-il un lien entre la réflexion théorique et les expériences vécues sur le terrain ? Ainsi, nous nous efforcerons de démont[r]er ou de rejeter ces hypothèses au fur et à mesure que nous avancerons avec notre travail de création et développement d'un réseau de soins intégrés. Ce mémoire sera aussi l'occasion de vérifier l'adéquation des théories développées depuis quelques années concernant la mise en place d'une nouvelle forme organisationnelle comme étant une des possibles réponses aux défaillances du système de santé.
