description: This paper introduces an algorithm for the detection of change-points and the identification of the corresponding subsequences in transient multivariate time-series data (MTSD). The analysis of such data has become increasingly important due to growing availability in many industrial fields. Labeling, sorting or filtering highly transient measurement data for training Condition-based Maintenance (CbM) models is cumbersome and error-prone. For some applications it can be sufficient to filter measurements by simple thresholds or finding change-points based on changes in mean value and variation. But a robust diagnosis of a component within a component group for example, which has a complex non-linear correlation between multiple sensor values, a simple approach would not be feasible. No meaningful and coherent measurement data, which could be used for training a CbM model, would emerge. Therefore, we introduce an algorithm that uses a recurrent neural network (RNN) based Autoencoder (AE) which is iteratively trained on incoming data. The scoring function uses the reconstruction error and latent space information. A model of the identified subsequence is saved and used for recognition of repeating subsequences as well as fast offline clustering. For evaluation, we propose a new similarity measure based on the curvature for a more intuitive time-series subsequence clustering metric. A comparison with seven other state-of-the-art algorithms and eight datasets shows the capability and the increased performance of our algorithm to cluster MTSD online and offline in conjunction with mechatronic systems.

Projected Changes in Streamflow and Sea Level Rise in the Kilchis and Miami river basins: Summary of existing data and literature
Publisher: name: Climate Impacts Group
Year: 2013

The Nature Conservancy (TNC) is working to restore two tidal wetland properties along the Kilchis and Miami Rivers, located within the Tillamook bay in Oregon. Ultimately, the goal of these restoration efforts is to reestablish key habitats and foster a resilient ecosystem that is robust to future changes in climate. The two properties had previously been diked off from river and estuarine flow and converted to farmland – planned restoration efforts include removal of dikes and levees, restoration of river channels and floodplains, and creating suitable habitat for native species. Sea level rise and streamflow change projections are needed to inform restoration actions at the Kilchis site and evaluate the effectiveness of existing restoration at the Miami site. Current analyses have assumed historical values for streamflow and sea level – a new assessment is needed to provide projected changes in streamflow (both monthly flows and extremes) as well as the range of projections for sea level rise. Based on this need, TNC contracted the Climate Impacts Group (CIG) to provide an assessment of projected changes in hydrology and sea level based on existing CIG datasets and the scientific literature. This report describes the data, methods, and results involved in assessing future changes in streamflow, and provides a synthesis of existing research on sea level rise for the Pacific Northwest.

description: A two-dimensional system of soft particles interacting via a two-length-scale potential is studied. Density functional theory and Brownian dynamics simulations reveal a fluid phase and two crystalline phases with different lattice spacing. Of these the larger lattice spacing phase can form an exotic periodic state with a fraction of highly mobile particles: a crystal liquid. Near the transition between this phase and the smaller lattice spacing phase, quasicrystalline structures may be created by a competition between linear instability at one scale and nonlinear selection of the other.

An evaluation of the utility of fine-scale, downscaled climate projections for connectivity conservation planning in Washington State
Creators: name: Washington Wildlife Habitat Connectivity Working Group (WHCWG)
Publisher: name: Climate Impacts Group
Year: 2013

In addition to identifying linkage areas expected to facilitate climate-driven shifts in species ranges (i.e., climate-gradient corridors), the Working Group has also been exploring approaches for identifying linkage areas expected to continue providing connectivity as climate changes (i.e., climate-resilient corridors). As part of this work, we recently completed an evaluation of the utility of future climate change projections for identifying climate-resilient corridors. Specifically, we developed fine-scale temperature and precipitation projections, and asked whether they could be used to identify the most resilient areas within Washington Connected Landscapes Project connectivity networks, i.e., those core habitat areas and corridors projected to see relatively little climatic change, thereby presenting good long-term connectivity conservation investments. In this report, we describe the methods used to develop our fine-scale climate change projections, summarize projected future climatic conditions for Washington, and then evaluate the utility of the downscaled data for connectivity conservation planning. Finally, we discuss the potential utility of projections obtained from “downstream” impacts models (models that translate climate changes to changes in other variables, e.g., fire severity).

description: Frauen wurden von Lehrern wie Hieronymus gezielt zur Verbreitung des Christentums geworben. Das Christentum bot den Frauen aber auch neue Möglichkeiten der Lebensgestaltung und der sozialen Aufwertung: So führte zunächst das Martyrium als zweite Taufe, nach Beendigung der Christenverfolgungen dann die Askese als „innerweltliches Martyrium“ zur Nivellierung der Geschlechtsunterschiede und zur Überwindung der klassischen Rollenverteilung, wenn auch nicht ohne Einschränkungen und negative Folgen für die Frauen. Die Märtyrerakten zeigen, dass Frauen zwar dasselbe Strafmaß wie Männer erhielten, aber in der Darstellung ihrer Martyrien deutliche Unterschiede erkennbar sind.

Links between Pacific basin climatic variability and natural systems of the Pacific Northwest
Publisher: name: Climate Impacts Group
Year: 2002

This thesis is composed of three principal chapters, each describing a distinct line of inquiry: (1) Five paleoproxy reconstructions of Pacific Basin climatic variability are examined in order to identify the extent to which these records provide a coherent signal. A composite chronology of these records is well correlated with the Pacific Decadal Oscillation (PDO) index, and provides a better record of PDO variability than any of the constituent chronologies back to 1840. This record suggests that the PDO may not have been an important organizing structure in the North Pacific climate system over much of the 19th century. (2) Empirical Orthogonal Function (EOF) analysis is used to identify patterns in annual area burned by wildfire in the American Northwest. Extreme wildfire years are forced in part by antecedent drought and summertime blocking in the 500 hPa height field. However the response to these events is modulated by the ecology of the underlying forest. At more mesic forest types antecedent drought preconditions forests to burn, but is not a good predictor of area burned due to the rarity of subsequent ignition. At especially dry locations, blocking events alone can lead to increases in area burned even in the absence of antecedent drought. Summertime cyclones can also lead to increased area burned, probably due to dry lightning storms that bring ignition and strong winds but little precipitation. Management paradigms that rely on fuel treatments alone to eliminate large, intense fires are consequently unlikely to succeed. (3) A network of drought sensitive tree-ring chronologies is used to reconstruct flow on the Columbia River at The Dalles, Oregon, since 1750. Residual statistics from this model exhibit a positive trend over time, indicating a change in the relationship between drought and streamflow caused by changes in land use over the twentieth century. The multiyear drought of the 1930s was the second most severe on record, with a more intense drought occurring during the 1840s. The period from 1950 to 1987 is unique in the last 250 years with respect to the relative absence of multiyear droughts.

description: Objectif. Les conciliations d’entrée et de sortie présentent un intérêt certain dans le cadre des coopérations ville-hôpital. S’intéresser aux conciliations de transfert dans une même structure hospitalière s’avère tout aussi important. L’objectif de ce travail a été de faire un état des lieux de ce type de conciliations. Méthodes. Les prescriptions d’entrée et de sortie ont été analysées lors des transferts entre les structures de notre centre sur une période de 13 mois, de janvier 2018 à janvier 2019. Une analyse des divergences a été réalisée afin d’en identifier les causes. Pour ce faire, les divergences entre les prescriptions ont été répertoriées pour chaque patient en séparant les divergences intentionnelles (DI) des non intentionnelles (DNI). Résultats. Sur la période concernée, 157 transferts ont eu lieu et 80 prescriptions ont présenté des divergences. Le nombre total de divergences s’élève à 138 (38 DNI et 100 DI), plusieurs divergences pouvant être retrouvées sur une ordonnance. Les deux principales DI identifiées sont les arrêts volontaires de prescription à 56% (n=56) et les changements de posologie (diminution ou augmentation) à 20% (n=20). Concernant les DNI, les erreurs sont principalement des omissions de prescription (non reprise du traitement) pour 68% des DNI (n=26) et les erreurs de posologie pour 16% (n=6). Discussion. Cette étude a mis en évidence deux points critiques : l’absence d’outil informatique adapté pour la transcription du traitement et la nécessité d’une lettre de sortie formalisée. Au final, notre étude a permis de mettre en évidence l’importance de la conciliation de transfert afin de sécuriser la prise en charge médicamenteuse ; les divergences pouvant toucher des médicaments à risque avec un fort potentiel iatrogène. Ceci nous encourage à poursuivre cette activité au sein de notre établissement.

The development of a linear, stochastic, dynamical model of El Nino/Southern Oscillation
Publisher: name: Climate Impacts Group
Year: 1998

Much research has been devoted to physical models of the interannual SST variability in the Pacific known as El Nino/Southern Oscillation (ENSO). The Zebiak-Cane model (ZCM, 1987) has established the dominate view of ENSO as being a coupled ocean-atmosphere phenomenon that is chaotic and linearly unstable. Recently, the idea that ENSO irregularity might be caused by stochastic forcing has gained support. Here, a variant of the ZCM is developed which is linear and stable, but displays ENSO-like variability under moderate external forcing.A linearized version of the Battisti (1988) variant of the ZCM is developed. This linear ocean-atmosphere model (LOAM) has time invariant background states, and is subject to singular vector analysis. The principle singular vector for time periods, $\tau$, (the $\tau$-optimals) show the following characteristics. (1) The $\tau$-optimals grow more quickly than the most unstable mode (the ENSO mode). (2) The $\tau$-optimals develop into the ENSO mode by 90 days. (3) Optimals were produced which used only the SST IT-optimals) and which used only the ocean dynamics (r-optimals.) For $\tau$ greater than 60 days, both optimals produce ENSO modes (of the same phase). A T-optimal pattern with a 0.1 degree anomaly maximum produces the same size ENSO as a r-optimal pattern with a 1.2 meter maximum thermocline anomaly. (4) The full optimal is the linear combination of these two sub-optimals, where their relative sizes are determined by their relative weights in the norm. (5) Neutral and damped versions of LOAM show these same properties, and still display transient growth.A version of LOAM (with an annual cycle added) is subjected to parameter studies to find plausible parameter regimes that damp the ENSO mode while preserving the transient growth of the $\tau$-optimals. Increasing the ocean mechanical damping and decreasing the western boundary reflection has the desired effect. Four candidate models ranging from slightly damped to heavily damped are run in simulation and their output analysis. A moderately damped version, T.80, emerges as the candidate with a power spectrum and annual cycle of variance (of the Nino3 index) that are most like those from observations. The predictability limits are calculated, and display a similar pattern to the "spring barrier" of ENSO. The T.80 predictability limit ranges from 12 to 18 months, depending on the season. A stochastic differential equation version of LOAM (with an annual averaged background) is developed to check some of the results of the stochastic simulations.

D’après ce rapport, les erreurs médicales constituaient la troisième cause de décès aux États-Unis. Au Québec, le Rapport Francœur publié en 2001 a eu le même effet, ce qui incita le gouvernement du Québec à mettre en place la loi 113 imposant la création de comités de gestion des risques au sein des établissements de soins et services et la déclaration obligatoire des évènements indésirables. En 2014, le projet de loi 83 a permis la création de postes de commissaire aux plaintes et de comités de vigilance et de la qualité dans tous les établissements afin de renforcer l’imputabilité en gestion des risques. En outre, la réforme de 2015 qui a amené à la création des Centres intégrés universitaires ou pas de santé et de services sociaux (CIUSSS) et (CISSS) a créé les directions de la qualité, de l’évaluation, de la performance et de l’éthique (DQEPE) afin de permettre une meilleure coordination de la qualité et de la sécurité des soins et services et de faciliter l’engagement des patients. De plus, l’engagement des patients en gestion des risques a pris son envol grâce aussi au Plan stratégique national 2015-2020 et au Cadre de référence de l’approche de partenariat entre les usagers, leurs proches et les acteurs en santé et en services sociaux qui ont été publiés dans la foulée. Une première étude longitudinale débutée en 2015 offre un survol de l’évolution des stratégies d’engagement des patients en gestion des risques mises en place dans les établissements de santé et services sociaux au Québec, en plus de proposer certaines recommandations.
Dimension Changing Phase Transitions in Instanton Crystals

description: We investigate lattices of instantons and the dimension-changing transitions between them. Our ultimate goal is the 3D->4D transition, which is holographically dual to the phase transition between the baryonic and the quarkyonic phases of cold nuclear matter. However, in this paper (just as in [1]) we focus on lower dimensions -- the 1D lattice of instantons in a harmonic potential V M_2^2x_2^2+M_3^2x_2^2+M_4^2x_4^2 and the zigzag-shaped lattice as a first stage of the 1D->2D transition. We prove that in the low- and moderate-density regimes, interactions between the instantons are dominated by two-body forces. This drastically simplifies finding the ground state of the instantons' orientations, so we made a numeric scan of the whole orientation space instead of assuming any particular ansatz. We find that depending on the M_2/M_3/M_4 ratios, the ground state of instanton orientations can follow a wide variety of patterns. For the straight 1D lattices, we found orientations periodically running over elements of a Z_2, Klein, prismatic, or dihedral subgroup of the SU(2)/Z_2, as well as irrational but link-periodic patterns. For the zigzag-shaped lattices, we detected 4 distinct orientation phases -- the anti-ferromagnet, another abelian phase, and two non-abelian phases. Allowing the zigzag amplitude to vary as a function of increasing compression force, we obtained the phase diagram for the straight and zigzag-shaped lattices in the (force, M_3/M_4), (chemical potential, M_3/M_4), and (density, M_3/M_4) planes. Some of the transitions between these phases are second-order while others are first-order. Our techniques can be applied to other types of non-abelian crystals.

Complex Langevin dynamics provides a possible solution, but it has to be applied with care. In this review, we first summarise our current understanding of the approach, combining analytical and numerical insight. In the second part we study SL(N,C) gauge cooling, which was introduced recently as a tool to control complex Langevin dynamics in nonabelian gauge theories. We present new results in Polyakov chain models and in QCD with heavy quarks and compare various adaptive cooling implementations.

Der Humanismus im Kontext alternativer Begründungsmodelle des Gymnasiums

Publisher: name: Pegasus-Onlinezeitschrift
Year: 2017

description: In einem knappen historischen Überblick soll gezeigt werden, dass sich die Existenz unterschiedlicher Humanismuskonzeptionen aus der Einwirkung vieler ideengeschichtlicher Faktoren erklärt. So stehen humanistische Ansätze in permanenter Wechselwirkung mit realistischem, christlichem, historistisch-hermeneutischem und nationalem bzw. europäischem Gedankengut.

Außerdem macht die historische Analyse deutlich, wie stark der Humanismus schon die neuzeitliche Schulgeschichte bis ins 18. Jahrhundert und besonders die deutsche Gymnasialgeschichte seit Beginn des 19. Jahrhunderts bis in die 60er Jahre des 20. Jahrhunderts mitprägte. Dennoch setzte schon in den 50er Jahren des letzten Jahrhunderts eine teilweise massive moralisch, wissenschaftsmethodisch und grundsätzlich weltanschaulich motivierte Humanismuskritik ein. Diese Vorbehalte gegen den Humanismus wurden im Rahmen der wissenschaftlichen Pädagogik von dialektisch-theologischer, existentialistischer Seite und verstärkt ab Mitte der 60er Jahre von den Vertretern der sog. „Realistischen Wende“ vorgetragen. Gegenwärtig wird angesichts der unangefochtenen Dominanz realistisch-pragmatischer bildungstheoretischer Konzepte der Humanismus in der (gymnasial)pädagogischen Diskussion weniger argumentativ bekämpft, denn angesichts seines zunehmenden gesellschaftlichen Bedeutungsverlusts stillschweigend marginalisiert.

description: La qualité perçue par les patients est une dimension importante de l’évaluation de la performance hospitalière. Fondé sur une analyse historique et une revue de la littérature, cet article présente un état des connaissances sur le développement d’indicateurs dans le domaine. Une première génération d’indicateurs a porté sur des enquêtes de satisfaction, puis d’expérience. Plus récemment sont apparus des indicateurs s’appuyant sur des données rapportées par les patients, sans traitement par un intermédiaire, les patient-reported outcomes (PRO). Si des initiatives émergent sur ce dernier thème, différents défis apparaissent en même temps, portant sur les modes de recueil, les capacités à comparer les établissements sur cette base et à engager des actions d’amélioration. D’une manière générale, les développements futurs pourraient à la fois consister en un déploiement de ce type d’indicateurs dans l’espace élargi du parcours du patient, mais aussi paradoxalement en des évaluations plus individuelles et personnalisées, au-delà de l’analyse agrégée à partir de la moyenne des indicateurs.

description: We investigate chiral graphene nanoribbons using projective quantum Monte Carlo simulations within the local Hubbard model description and study the effects of electron-electron interactions on the electronic and magnetic properties at the ribbon edges. Static and dynamical properties are analyzed for nanoribbons of varying width and edge chirality, and compared to a self-consistent Hartee-Fock mean-field approximation. Our results show that for chiral ribbons of sufficient width, the spin correlations exhibit exceedingly long correlation lengths, even between zigzag segments that are well separated by periodic armchair regions. Characteristic enhancements in the magnetic correlations for distinct ribbon widths and chiralities are associated with energy gaps in the tight-binding limit of such ribbons. We identify specific signatures in the local density of states and low- energy modes in the local spectral function which directly relate to enhanced electronic correlations along graphene nanoribbons and which can be accessed scanning tunneling spectroscopy.

description: Es gibt wohl kaum einen Autor im Bereich der alten Sprachen, der in den letzten Jahren einem breiten Publikumskreis derart intensiv ins Bewusstsein gerückt wurde wie Homer. Der Troia-Film von Wolfgang Petersen, die Kontroverse um die Grabungsergebnisse von Troia und die aufsehenerregenden Theorien von Raoul Schrott inclusive seiner neuen Ilias-Übersetzung wurden über die Medien in einer bislang unbekannten Intensität auch außerhalb des wissenschaftlichen und schulischen Rahmens diskutiert. Es ist jedoch nicht nur dieser Befund, der es notwendig erscheinen lässt, die Entwicklung der Homerforschung in einem konzisen Überblick vorzustellen. Ebensfalls erwähnenswert ist auch die Tatsache, dass die Beschäftigung mit den homerischen Epen inzwischen relativ wenig mit der Textdeutung, wie sie früher betrieben wurde, zu tun hat. Stattdessen haben sich die Soziologie, die Psychologie und der Strukturalismus im Interpretationsbereich fest etabliert. Darüber hinaus wurden die homerischen Epen intensiven Analysen durch Historiker, Archäologen und Sprachwissenschaftler unterzogen, mit zum Teil sehr aufschlussreichen Ergebnissen. Dieser  Entwicklung entsprechend stellt der ausgewiesene Homer-Kenner Edzard Visser die Hauptlinien der Homerforschung  der letzten 20 Jahre dar; dabei fließen auch didaktische Aspekte in die Betrachtung ein.

description: The use of computational methods in the Social Sciences has many roots. Classic examples include the fitting of measurement-, as well as structural models or the recognition of simulation as a third way of doing science. More recently, the availability of large organic datasets has led to the emergence of Computational Social Science. All these examples have in common that potentially compute-intensive and complex analysis pipelines are an essential part of the research. Reproducibility is the cornerstone of modern science. Yet more work is needed to make reproducibility the norm for complex computational analysis pipelines. GESIS Notebooks aims to close this gap in the Social Sciences by supporting reproducible computational analysis pipelines that enable researchers to focus on the methodological aspects of their work while increasing their visibility and following best open-science practices simultaneously. The service does not try to reinvent the wheel but reuses existing technology whenever possible. Execution, place, and content are the concepts of the service, and in the remainder, we will look at each of them.

Graceful exit from inflation for minimally coupled Bianchi A scalar field models
Creators: name: Beyer, Florian

Publisher: name: arXiv
Year: 2013
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We consider the dynamics of Bianchi A scalar field models which undergo inflation. The main question is under which conditions does inflation come to an end and is succeeded by a decelerated epoch. This so-called "graceful exit" from inflation is an important ingredient in the standard model of cosmology, but is, at this stage, only understood for restricted classes of solutions. We present new results obtained by a combination of analytical and numerical techniques.

description: Purpose In this study, the authors investigated adult word learning to determine how neighborhood density and practice across phonologically related training sets influence online learning from input during training versus offline memory evolution during no-training gaps.
Method Sixty-one adults were randomly assigned to learn low- or high-density nonwords. Within each density condition, participants were trained on one set of words and then were trained on a second set of words, consisting of phonological neighbors of the first set. Learning was measured in a picture-naming test. Data were analyzed using multilevel modeling and spline regression. Results Steep learning during input was observed, with new words from dense neighborhoods and new words that were neighbors of recently learned words (i.e., second-set words) being learned better than other words. In terms of memory evolution, large and significant forgetting was observed during 1-week gaps in training. Effects of density and practice during memory evolution were opposite of those during input. Specifically, forgetting was greater for high-density and second-set words than for low-density and first-set words.
Conclusion High phonological similarity, regardless of source (i.e., known words or recent training), appears to facilitate online learning from input but seems to impede offline memory evolution.

description: Excerpts from the Foreword: Concern about pesticides first came to a focus through the efforts of Rachel Carson and others who called attention to their effects on the environment. For a long time little thought was given to measuring the economic consequences of pesticide use. The issues seemed beyond the pale of economics in the realm of incommensurable pesticides social benefits and losses. Some saw pesticides as essential in preventing food shortages, while others were impressed to with the harm done to the environment. More recently we have come to realize that economic measurement and appraisal can help solve the pesticides problem. This symposium reviewed the present status of economic research on and identified new areas to meet future needs for policy decisions.

title: Dossier : la place du patient – Partenariat thérapeutique et sécurité des soins : réflexions sur la perspective patient
Creators: name: Cousineau, Julie
Publisher: name: Health & Co

description: L’engagement du patient dans ses soins est devenu une priorité pour plusieurs organisations de santé, qui promeuvent un partenariat favorisant son empowerment. En matière de sécurité des soins, la plupart des initiatives se concentrent sur des stratégies orientées vers les cliniciens ou le système de réduction des risques. Les recherches adoptant une « perspective patient » s’intéressent surtout aux actes démontrant un engagement du patient, ou visent à comprendre les limites de celui-ci. Il apparaît que la relation de soin et la communication qui l’accompagne sont les vecteurs essentiels de la réalisation de ce partenariat afin d’améliorer la gestion de la sécurité des soins. Or cette relation de soin peut être mise à l’épreuve lorsque survient un évènement indésirable ou un accident de soin : d’une part, les cliniciens peuvent se sentir responsables, mal à l’aise face à ces évènements, et avoir des difficultés à expliquer ces enjeux aux patients, voire être eux-mêmes considérés comme victimes ; d’autre part, les patients peuvent parfois identifier certains défis de sécurité, mais ne pas savoir comment en parler aux équipes de soin. Une compréhension plus large de la notion d’engagement du patient basée sur ses stratégies de sécurité s’impose mais des pistes de solution concrètes pour outiller les acteurs manquent encore.

title: Dossier : la place du patient – Les représentants d’usagers dans l’amélioration de la qualité et la sécurité des soins : exemple de la lutte contre les infections nosocomiales
Creators: name: Jarno, Pascal
Publisher: name: Health & Co

description: Contexte. Le dispositif de représentation des usagers est désormais bien implanté en France. Il repose sur l’implication de plus de 6 000 représentants des usagers (RU) qui donnent de leur temps, se forment, apprennent à échanger avec les gestionnaires et les professionnels de santé pour faire valoir les droits des usagers. Mais la question de la place des RU dans les établissements de santé reste posée. Objectif. L’objectif général de ce travail est d’évaluer la perception des usagers et des professionnels de l’implication des RU dans l’amélioration de la qualité-sécurité des soins au sein des établissements de santé afin de définir les modalités les plus adaptées de soutien de cette implication. Méthode. Nous nous sommes appuyés sur une méthode qualitative par focus groupes constitués de RU et professionnels. Résultat. Le RU est perçu positivement comme un autre regard, une interface. Les difficultés mises en avant sont : l’inégalité de formation, la non-connaissance du rôle des RU par les professionnels, la non-identification des RU et donc leur non-sollicitation par les patients. Conclusion. Si la formation, essentielle, est insuffisante, la question centrale posée par cette étude est le défaut de valorisation de la fonction de représentation (au profit de modalités plus individuelles de participation comme les « patients experts ») qui renvoie plus largement à la crise de la démocratie représentative au sein de notre société et à la capacité du RU à porter un point de vue collectif.

description: En France, la place croissante occupée par les patients et leurs représentants dans la définition du système de santé incarne l’enjeu porté par le concept de démocratie en santé. Les mutations successives du statut de la personne soignée depuis le XVIIIe siècle, dont l’évolution des termes pour la nommer témoigne – de « malade » à « patient » à « usager » –, en parallèle de l’évolution de la science et de la pratique médicale, ont abouti à l’apparition de « patient acteur ». Celui-ci peut participer à différents degrés auprès des professionnels de santé et des décideurs à orienter le système de santé vers davantage de prise en compte des perspectives des patients et usagers. Une enquête réalisée dans les centres hospitaliers universitaires (CHU) de Nantes et Rennes a cherché à décrire les initiatives entreprises par les professionnels de santé exerçant au sein de ces CHU pour faire participer les patients et leurs représentants dans la dispensation des soins, la qualité et la sécurité des soins, la formation et la recherche. Elle a permis, grâce à un partenariat avec une équipe de l’École de Santé publique de l’Université de Montréal, de proposer une démarche d’évaluation globale au sein des CHU français. Celle-ci a associé à la diffusion nationale de cette enquête une deuxième enquête auprès des directions, explorant les stratégies en place pour promouvoir la participation des patients et usagers dans la qualité et la sécurité des soins au sein des institutions.
On the Solution of General Impulse Control Problems Using Superharmonic Functions

description: In this paper, a characterization of the solution of impulse control problems in terms of superharmonic functions is given. In a general Markovian framework, the value function of the impulse control problem is shown to be the minimal function in a convex set of superharmonic functions. This characterization also leads to optimal impulse control strategies and can be seen as the corresponding characterization to the description of the value function for optimal stopping problems as a smallest superharmonic majorant of the reward function. The results are illustrated with examples from different fields, including multiple stopping and optimal switching problems.
