    Full Text Available L’évolution des itinéraires techniques viticoles (ITKv vers un plus grand respect de l’environnement passe par une évaluation de leurs performances environnementales. Dans un contexte de gestion durable, plusieurs autres facteurs sont à prendre en compte, notamment le risque de modification de la qualité des raisins issus de ces ITKv. Les résultats d’évaluation environnementale par la méthode d’Analyse du Cycle de Vie (ACV ainsi que l’évaluation de la qualité du raisin s’appuient sur beaucoup données. Ce travail montre l’intérêt d’une méthode d’évaluation multicritère conjointe « environnement et qualité », dans le processus de changement de pratiques pour une amélioration des performances. Les résultats obtenus sur 5 ITKv montrent des différences de notes entre les 2 millésimes étudiés et des pratiques ont été identifiées pour leurs forts impacts sur les résultats ACV. Des propositions théoriques de changement de pratiques sont testées sur l’un des ITKv. Ces propositions améliorent les notes environnementales finales de +0,15 points à +0,77 points (/10 quand elles sont mises en œuvre séparément et +2,29 points (/10 en étant combinées. Un modèle explicatif de la qualité du raisin permet de vérifier que les nouvelles pratiques ne peuvent potentiellement pas altérer la qualité du raisin. La méthode d’évaluation conjointe CONTRA-QUALENVIC adaptée à la viticulture montre ici qu’elle peut être une aide à l’amélioration des ITKv.

Certains liens présents dans ce modèle sont discutés à travers une étude de cas.

  3. Quelle place pour le citoyen dans les processus de qualification environnementale des entreprises ?

    2006-01-01

    Full Text Available Le développement durable invite à intégrer aux modèles de raisonnement et d’action économiques la négociation entre parties intéressées et compétentes. Cette approche trouve sa traduction dans le champ économique sous la forme de la « théorie des parties prenantes », cristallisé notamment dans des outils comme la norme ISO 14001. Mais les modalités pratiques de sa mise en oeuvre ne permettent pas une intégration équilibrée des différents points de vue en présence. Le dialogue des parties prenantes qui vise à construire la « qualité environnementale » des entreprises se négocie essentiellement au sein de l’espace marchand. Le potentiel d’intégration du droit de négociation des parties prenantes paraît faible en l’absence d’un dispositif de veille citoyenne de cette qualité environnementale.Sustainable development aims to integrate stakeholder negotiation into economical reasoning and acting models. The stakeholder theory translates this approach in the economics field. Some tools like ISO 14001 standard crystallise this theory. But the practical ways of its implementation do not allow a balanced integration of the hole range of stakeholders views. Stakeholder dialog, which aims to build a consensus about enterprises “environmental quality”, is mostly negotiated inside the economic space. ISO 14001 standardisation system is not likely to allow stakeholder negotiation rights integration while citizens do not organise an environmental quality watching over network.

    From 10 to 14 November, twenty-two companies presented their latest technology at the Haute-Savoie exhibition at CERN. With hedges of green plants, wooden lawn chairs, and even a small fountain like the ones near mountain chalets, the exhibitors transformed the hall of the main building into a little natural corner. They not only brought local flair but also a multitude of interesting information about their know-how of innovative technologies. In addition to the exhibition, presentations on topics ranging from multiplexing over materials to nano-technologies were given at the end of each afternoon in the Council Chamber.

  5. Gouvernance environnementale locale et comportements économiques

    Full Text Available La notion de gouvernance est mobilisée de manière croissante aujourd’hui pour évoquer de nouvelles formes de coopérations entre acteurs de la vie économique et sociale. Appliquée aux questions environnementales, la gouvernance pose à la fois la question de la maîtrise du temps par les acteurs et celle du territoire d’application des décisions prises. On peut donc considérer qu’elle engage un renouvellement de l’articulation entre le temps et l’espace, que doit prendre en compte l’analyse des choix économiques dans ce domaine. L’exemple du bassin d’emploi dunkerquois montre que cette articulation est au cœur d’une participation des entreprises à la gouvernance environnementale.The concept of governance is more and more raised to conjure up new ways of cooperation between actors of the economic and social life. Applied to environmental matters, governance ask both the question of mastery of the time and the one of the territory’s application for taken decisions. We can consider that it engage a renewal of the joint between time and space, that the analysis of economic choices had to take into account. The example of “Dunkerque” show that this joint is the heart of firm’s collaboration in environmental governance.

    Guilloux-Viry, M.; Perrin, A.

    1998-08-01

    High critical temperature superconductors (HTCS) are very promising for applications in microelectronics due to the control of high quality epitaxial thin films, in spite of a number of specific constraints. Active and passive devices are already available in various laboratories, prooving that applications are actually expected soon. We report here on the interest of HTCS thin films, on preparation processes including materials and substrates choice, and also on characterization methods which are required in order to chek the quality of the samples. Finally some illustrative examples of applications are presented. Les supraconducteurs à haute température critique ouvrent des perspectives prometteuses dans le domaine de l'électronique en raison de la maîtrise de la croissance de films minces de haute qualité cristalline et physique, malgré des difficultés spécifiques. Des dispositifs, aussi bien actifs que passifs, commencent à être réalisés dans divers laboratoires, montrant que des applications peuvent être effectivement envisagées à relativement court terme.

There one drives innovation and investments with the objective of fulfilling by 2050 their own needs completely by renewable sources. The orientation to supplies Jeremy Rifkin idea of the third industrial revolution. If successful, the region would be on climate protection well ahead of the national targets, the 2050 ''only'' provide a CO{sub 2} emission reduction of 75%. In addition to the Research and development (R and D) to many future ideas in Hauts-de-France but also some major projects for Security of European energy supplies are realized that show the local agility. [German] Frankreich hatte sich im Vorfeld des letztjaehrigen Pariser-Klimagipfels auf ambitionierte Energiewendeziele festgelegt. Insbesondere die 2016 neu gebildete Region Hauts-de-France sticht dabei als Vorreiter heraus. Dort treibt man Innovationen und Investitionen mit dem Ziel an, bis 2050 den Eigenbedarf vollstaendig mittels erneuerbarer Quellen zu decken. Die Orientierung dazu liefert Jeremy Rifkins Idee der dritten industriellen Revolution. Im Erfolgsfall laege die Region beim Klimaschutz deutlich vor den nationalen Zielen, die bis 2050 ''nur'' eine CO{sub 2}-Emissionsreduktion von 75 % vorsehen. Neben der Forschung und Entwicklung (F and E) zu vielen Zukunftsideen werden in Hauts-de-France aber auch einige Grossprojekte zur Absicherung der europaeischen Energieversorgung realisiert, die Ausweis der dortigen Agilitaet sind.

  1. Ifp's New Flexible Hydrocracking Process Combines Maximum Conversion with Production of High Viscosity, High Vi Lube Stocks Le nouveau procédé IFP d'hydrocraquage à haute flexibilité combine conversion maximum et production de bases, huile à haute viscosité et à indice de viscosité élevé

    Full Text Available Institut Français du Pétrole (IFP has developed a new dual catalytic system for its hydrocracking process that enables high conversion to middle distillates and production of high viscosity, high VI lube stocks. Although the hydrocracking process is mainly devoted to the conversion of vacuum distillates, deasphalted oil or mixture of both into high quality middle distillates, it can also produce a residue, that after dewaxing will be a very high VI lube base oil. In this presentation major emphasis is put on the possibility to produce very high VI lubes with high viscosity thanks to the development of the new catalytic system. Large flexibility in feedstock selection and easy control of operating variables allow the production of all grades of lube oils associated with high quality middle distillates for a large range of conversion levels. L'Institut Français du Pétrole (IFP a mis au point, pour son procédé d'hydrocraquage, un nouveau système catalytique à 2 catalyseurs qui permet une forte conversion en distillats moyens et la production de fractions lubrifiantes à haute viscosité et indice de viscosité élevé. Si le procédé d'hydrocraquage est essentiellement utilisé pour la conversion de distillats sous vide, d'huile désasphaltée ou d'un mélange des deux en distillats moyens de haute qualité, il peut aussi produire un résidu qui, après déparaffinage, fournira une base pour lubrifiant à indice de viscosité très élevé. Cet article souligne particulièrement la possibilité de produire des lubrifiants à indice de viscosité très élevé et haute viscosité, grâce à ce nouveau système catalytique. Une grande flexibilité dans le choix des produits à traiter et la facilité de contrôle des paramètres opératoires permet la production de toutes les qualités d'huiles lubrifiantes associées à des distillats moyens de haute qualité, pour une large gamme de niveaux de conversion.

  3. Passing through: queer lesbian film and Fremde Haut.

    Science.gov (United States)

    Aaron, Michele

    2012-01-01

    Expanding the horizons of lesbian film, Fremde Haut is located within three broad frames: the cross-dressing genre, the New Queer Cinema (NQC) movement, and an Accented or diasporic film aesthetic. While strong connections exist between the cross-dressing film and NQC, less addressed are the links between the New Queer and the Accented yet these are of more radical, that is queerer, potential. Through Fremde Haut, this article illustrates how intimately tied to race and nation, gender and sexuality are, to reveal the accented as queer and the queer as accented. Ultimately, what is distinguished is the potency of a new "quare" cinema.

    2015-01-01

    This report aims to analyze the geothermal potential of the Meuse/Haute-Marne site selected for the Cigeo project, primarily based on data available in the literature and particularly on those recently Acquired by Andra near this site. It also analyzes the report made on the same topic by Geowatt AG at The request of the CLIS of Bure. For the Meuse/Haute-Marne area relevant to Cigeo, the present report concludes to the existence of A low-energy geothermal resource in the lower Triassic. For the Permian and the basement, a medium To high-energy geothermal resource is conceivable, but its occurrence is hypothetical. Beneath the site, exploiting the Triassic would depend on the possibility of re-injecting the produced Brine. National and international experiences show the difficulty to carry out such a reinjection in Silty-clayey formations. The profitability of such exploitation in the Triassic, the Permian or in the basement is questionable. Indeed, the Meuse/Haute-Marne area neither shows an exceptional nature nor a specific interest Compared to other formations or zones for which either the geothermal potential is better Demonstrated, such as for instance the Dogger formation in the central part of the Paris basin with Easier exploitation conditions, or where the geothermal gradients are higher.

  9. Andra in Meuse/Haute-Marne

    International Nuclear Information System (INIS)

    Mazoyer, David

    2016-11-01

    Every year, France generates tens of thousands of cubic metres of radioactive waste. This waste comes from various sectors which make use of the properties of radioactivity, including nuclear power generation, defence, industry, health care and research. At present, Andra operates two waste disposal facilities in the Aube where 90% of the total volume of radioactive waste generated every year is managed. For safety reasons, the remaining 10% cannot be disposed of at these surface facilities. Some of this waste, known as high-level waste (HLW) and intermediate-level long-lived waste (ILW-LL), is highly radioactive and can remain hazardous for several hundred thousand years. A suitable solution must be implemented to manage such waste, as set down in the Act of 28 June 2006: reversible disposal in a deep geological formation. Starting with its Underground Research Laboratory in Bure (in the Meuse department), on which construction began in 2000, Andra has gradually expanded the facilities at the Meuse/Haute-Marne Centre (CMHM) in the area. In 2007, the Perennial Observatory of the Environment (OPE) was set up to better understand changes over time in the natural environment around Andra's facilities and, in 2009, the Technological Exhibition Facility opened in Saudron (in the Haute-Marne department), to present the Cigeo geological disposal facility project. Last, the Environmental Specimen Bank opened in 2014. Here, environmental monitoring samples taken in connection with the OPE are conserved for at least one hundred years. In addition to contributing to development of the two departments by creating jobs and purchasing from local suppliers, Andra has been committed to working alongside local players for the last twenty years, becoming an integral part of economic, social and cultural life in the region. If the Cigeo project is approved, the site will become a leading industrial, research and education cluster for the region. This document presents: the Andra

    Fournier, Marie-Claude

    Une caracterisation des emissions atmospheriques provenant des sources fixes en operation, alimentees au gaz et a l'huile legere, a ete conduite aux installations visees des sites no.1 et no.2. La caracterisation et les calculs theoriques des emissions atmospheriques aux installations des sites no.1 et no.2 presentent des resultats qui sont en dessous des valeurs reglementaires pour des conditions d'operation normales en periode hivernale et par consequent, a de plus fortes demandes energetiques. Ainsi, pour une demande energetique plus basse, le taux de contaminants dans les emissions atmospheriques pourrait egalement etre en dessous des reglementations municipales et provinciales en vigueur. Dans la perspective d'une nouvelle reglementation provinciale, dont les termes sont discutes depuis 2005, il serait souhaitable que le proprietaire des infrastructures visees participe aux echanges avec le Ministere du Developpement Durable, de l'Environnement et des Parcs (MDDEP) du Quebec. En effet, meme si le principe de droit acquis permettrait d'eviter d'etre assujetti a la nouvelle reglementation, l'application de ce type de principe ne s'inscrit pas dans ceux d'un developpement durable. L'âge avance des installations etudiees implique la planification d'un entretien rigoureux afin d'assurer les conditions optimales de combustion en fonction du type de combustible. Des tests de combustion sur une base reguliere sont donc recommandes. Afin de supporter le processus de suivi et d'evaluation de la performance environnementale des sources fixes, un outil d'aide a la gestion de l'information environnementale a ete developpe. Dans ce contexte, la poursuite du developpement d'un outil d'aide a la gestion de l'information environnementale faciliterait non seulement le travail des personnes affectees aux inventaires annuels mais egalement le processus de communication entre les differents acteurs concernes tant intra- qu'inter-etablissement.

    2009-01-01

    The words Dublin or Ireland do not immediately come to mind when haute cuisine is mentioned. However, two leading French chefs, the brothers Francois and Michel Jammet, opened a restaurant in Dublin in 1901 which, up until its closure in 1967, remained one of the best restaurants serving haute cuisine in the world (Mac Con Iomaire 2005a; Mac Con Iomaire 2006). Haute cuisine was served in many Dublin hotels, clubs and restaurants during the twentieth century and came under similar influences a...

    Full Text Available The need to produce more sustainable buildings has been influencing the design decisions all over the world. That’s why it is imperative, in Brazil, the development of strategies and method to aid the decision making during the design process, focused on high quality environmental. This paper presents a decision support tool based on the principles of sustainable construction developed by the Project, Architecture and Sustainability Research Group (GPAS of Federal University of Rio de Janeiro – Brazil. The methodology has been developed for the selection of a preliminary design of a laboratory to be built at Rio Technology Park at the University campus. The support provided by GPAS occurred in three stages: the elaboration of the Reference Guide for the competitors, the development of a methodology to evaluate the proposed solutions (based on environmental performance criteria and the assistance of the members of jury in the trial phase. The theoretical framework was based upon the concepts of the bioclimatic architecture, the procedures specified by the certification HQE® (Haute Qualité Environnementale and the method suggested by the ADDENDA® architecture office. The success of this experience points out the possibility to future application in similar cases.

    Full Text Available La valeur patrimoniale des kumaru, espèces de poissons appartenant à la sous-famille des Serrasalminae, a été approchée selon des critères faisant référence à leur place au sein de la biodiversité ou de la sociodiversité. Du point de vue de l’anthropologue, les kumaru apparaissent indéniablement comme les espèces de poissons ayant globalement les plus fortes valeurs sociale, hédonique, économique, non seulement chez les Amérindiens Wayana du Haut Maroni, mais aussi chez les Noirs Boni du cours moyen. On peut les qualifier à ce titre d’espèces patrimoniales. Du point de vue du biologiste, les trois espèces de kumaru du Haut Maroni se situent à des niveaux d’endémicité différents, mais toutes participent au fonctionnement du biotope particulier des herbiers à Podostemaceae, au moins dans leurs jeunes stades. Au-delà de la simple conservation des espèces, le mode de distribution de l’asitau (Prosomyleus rhomboidalis et la position du watau yaikë (Tometes lebaili dans la phylogénie des Serrasalminae leur confèrent un ensemble de qualités entrant dans l’évaluation de leur valeur patrimoniale.

Dans une première partie, les DEV seront présentées comme une réponse spécifique des producteurs à ce type de conflit, la seconde partie se concentrant sur une lecture des DEV en termes de proximité. Une enquête réalisée auprès des producteurs inscrits en agriculture raisonnée ou biologique permet de montrer que la proximité organisée ne peut être porteuse à elle seule de solutions aux divergences d’intérêts entre acteurs.This paper analyses, terms of geographical and organized proximity, the contribution of Voluntary Environmental Approaches (VEA to the resolution of diffuse conflicting water uses in vine growing and fruit-bearing arboriculture. In a first part, we show that VEAs are a specific producer’s response to this kind of conflicts, the second part being centred on an analysis of VEAs in terms of proximity. An investigation towards producers engaged in integrated or organic farming shows that organized proximity alone is not able to bear solutions to divergences of interests between actors.

    Lombard, Pamela J.

    2013-01-01

    Digital flood-inundation maps for a 6.3-mi reach of the Wabash River from 0.1 mi downstream of the Interstate 70 bridge to 1.1 miles upstream of the Route 63 bridge, Terre Haute, Indiana, were created by the U.S. Geological Survey (USGS) in cooperation with the Indiana Department of Transportation. The inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science Web site at http://water.usgs.gov/osw/flood_inundation/, depict estimates of the areal extent of flooding corresponding to select water levels (stages) at the USGS streamgage Wabash River at Terre Haute (station number 03341500). Current conditions at the USGS streamgage may be obtained on the Internet from the USGS National Water Information System (http://waterdata.usgs.gov/in/nwis/uv/?site_no=03341500&agency_cd=USGS&p"). In addition, the same data are provided to the National Weather Service (NWS) for incorporation into their Advanced Hydrologic Prediction Service (AHPS) flood warning system (http://water.weather.gov/ahps//). Within this system, the NWS forecasts flood hydrographs for the Wabash River at Terre Haute that may be used in conjunction with the maps developed in this study to show predicted areas of flood inundation. In this study, flood profiles were computed for the stream reach by means of a one-dimensional step-backwater model. The model was calibrated using the most current stage-discharge relation at the Wabash River at the Terre Haute streamgage. The hydraulic model was then used to compute 22 water-surface profiles for flood stages at 1-ft interval referenced to the streamgage datum and ranging from bank-full to approximately the highest recorded water level at the streamgage. The simulated water-surface profiles were then combined with a geographic information system digital elevation model (derived from Light Detection and Ranging (LiDAR) data having a 0.37-ft vertical accuracy and a 1.02-ft horizontal accuracy) to delineate the area flooded at each water

  5. An Analysis of the Most Adopted Rating Systems for Assessing the Environmental Impact of Buildings

    Directory of Open Access Journals (Sweden)

    2017-07-01

    Full Text Available Rating systems for assessing the environmental impact of buildings are technical instruments that aim to evaluate the environmental impact of buildings and construction projects. In some cases, these rating systems can also cover urban-scale projects, community projects, and infrastructures. These schemes are designed to assist project management in making the projects more sustainable by providing frameworks with precise criteria for assessing the various aspects of a building’s environmental impact. Given the growing interest in sustainable development worldwide, many rating systems for assessing the environmental impact of buildings have been established in recent years, each one with its peculiarities and fields of applicability. The present work is motivated by an interest in emphasizing such differences to better understand these rating systems and extract the main implications to building design. It also attempts to summarize in a user-friendly form the vast and fragmented assortment of information that is available today. The analysis focuses on the six main rating systems: the Building Research Establishment Environmental Assessment Methodology (BREEAM, the Comprehensive Assessment System for Built Environment Efficiency (CASBEE, the Deutsche Gesellschaft für Nachhaltiges Bauen (DGNB, the Haute Qualité Environnementale (HQETM, the Leadership in Energy and Environmental Design (LEED, and the Sustainable Building Tool (SBTool.

    Das Rhizom von Potentilla officinalis (PO) ist reich an Gerbstoffen und wird traditionell zur äußerlichen Behandlung von Entzündungen der Haut und der Schleimhäute verwendet. Ziel der vorliegenden Arbeit war die Bestätigung der antiinflammatorischen Eigenschaften von PO mittels eines UV-Erythem-Tests und einer klinischen Anwendungsstudie bei atopischer Haut. Die antiinflammatorische Wirkung eines PO-Extrakts (standardisiert auf 2 % Trockensubstanz) wurde in einer prospektiven, randomisierten, placebokontrollierten Doppelblindstudie mit 40 gesunden Erwachsenen im UV-Erythem-Test im Vergleich zu 1 % Hydrocortisonacetat untersucht. Im Rahmen einer prospektiven nicht kontrollierten Studie wurde die Wirkung und Verträglichkeit der 2 % PO-Creme an zwölf Erwachsenen und zwölf Kindern mit atopischer Haut nach Anwendung über zwei Wochen in einem definierten Testareal anhand eines Teil-SCORAD untersucht. Zusätzlich wurde die Beeinflussung der Hautrötung im Testareal photometrisch gemessen. Im UV-Erythem-Test zeigte die PO-Creme eine signifikante Reduktion des Erythemindex im Vergleich zum Vehikel. Die antiinflammatorische Wirkung des Verums entsprach der der 1 % Hydrocortisonacetat-Creme. Die klinische Studie bei Atopikern zeigte eine signifikante Abnahme des Teil-SCORAD und des Erythems im Testareal. Es wurden keine Unverträglichkeitsreaktionen beobachtet. PO als 2%ige Zubereitung besitzt entzündungshemmende Eigenschaften und ist wirksam und gut verträglich auf atopischer Haut. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

    International Nuclear Information System (INIS)

    Oukemeni, D.; Krogh, T.E.

    1995-01-01

    The Aouli Pluton consists of four units: (1) granodiorite; (2) grey granite; (3) pink granite - these three units constituting a spatially continuous massif, and (4) muscovite granite, which is exposed in two small stocks somewhat removed from the other units. U-Pb ages obtained on zircon and titanite are 333 ± 2 Ma and 319 ± 1.5 Ma for the granodiorite and grey granite respectively. The 14 ma age difference between the granodiorite and the grey granite supports the multiple injection hypothesis which was the outcome of geochemical studies (Oukemeni and Bourne, 1993). These two rocks also contain an inherited component which has been dated at 1520 Ma in the granudiorite and at 1245 ma and 1804 Ma in the grey granite. The inherited components suggest the possible presence of Precambian crust below the Haute Moulouya. Since the intrusion is late-to post-tectonic (Oukemeni and Bourne, 1993), the age of the granodiorite (333 ± 2 Ma) indicates that the Hercynian deformation is pre-Visean in the Haute Moulouya area, and, by extension, throughout the eastern meseta region.

    Escoffier, S

    2002-04-01

    Within the framework of a feasibility study of underground radioactive waste repository the experimental characterization of the coupled behavior of the host layer is of first importance. This work concerns the experimental characterization in laboratory of the poro-elastic behavior of argillite which constitutes the host layer of the future underground laboratory of ANDRA located at the limit of the Meuse/Haute-Marne. The theoretical approach is the Mechanics of Porous Media defined by Coussy [1991] which has the advantage of providing a formulation of the behavior laws using measurable parameters in laboratory. The difficulties or the feasibility of the characterization tests of these rocks coupled behavior are related to their very low permeability which requires an adaptation of the experimental devices initially used on more permeable rocks. Initially a synthesis on the knowledge of the poro-elastic parameters of Meuse/Haute-Marne argillite is given. Thereafter a first approach of the use of the studies of sensitivity as tools of decision-making aid is proposed. The experimental difficulties encountered by the various experimenters are illustrated by the diversity of the experimental choices, the test duration or by the results disparity. Because of economic, political and ecological stake, the studies of sensitivity could make it possible to direct the experimental efforts by giving indications on the dominating parameters in the coupled behavior of a rock. In the second time after the presentation of the test results of physical characterization 3 types of tests are described: permeability test (pulse test), determination of Biot coefficient under odometric loading and isotropic drained test. The complexity of these tests is related to the attack of the experimental limits. They are presented in detail: theoretical recalls, experimental set up, experimental protocol, unfolding and test results. (author)

    Summary Les brûlures électriques par haut voltage sont responsables de gros dégâts tissulaires en immédiat et dans les jours suivant l’accident du fait de la chaleur importante dégagée par effet joule et de la thrombose microvasculaire évolutive. Les pertes de substances du scalp secondaires à ces brûlures nécessitent une couverture par lambeaux vu la destruction du périoste et du calvarium en regard. De juin 1997 à juin 2008, 15 patients ont été traités pour des pertes de substance du scalp secondaires à des brûlures électriques par haut voltage de diamètre allant de 8 à 11 cm et siégeant dans la région tonsurale. Ces patients ont été opérés dans la première semaine suivant l’accident. Les pertes de substance du scalp de taille moyenne secondaires à ces brûlures peuvent être couvertes per primam de façon fiable par des lambeaux locaux axialisés et multiples. Nous relatons l’expérience du Service de Chirurgie Plastique du Centre Hospitalier Universitaire Ibn-Sina, Rabat, Maroc, dans la gestion et la prise en charge de ces brûlures. PMID:22262963

    Full Text Available Background: In Burkina Faso, phytotherapy is the main medical alternative used by populations to manage various diseases that affect the nervous system. The aim of the present study was to report medicinal plants with psychoactive properties used to treat neuropsychiatric disorders in the Hauts Bassins region, in the western zone of Burkina Faso. Methods: Through an ethnobotanical survey using structured questionnaire, 53 traditional healers (TH were interviewed about neuropsychiatric disorders, medicinal plants and medical practices used to treat them. The survey was carried out over a period of three months. Results: The results report 66 plant species used to treat neuropsychiatric pathologies. Roots (36.2% and leaves (29% were the main plant parts used. Alone or associated, these parts were used to prepare drugs using mainly the decoction and the trituration methods. Remedies were administered via drink, fumigation and external applications. Conclusions: It appears from this study a real knowledge of neuropsychiatric disorders in the traditional medicine of Hauts Bassins area. The therapeutic remedies suggested in this work are a real interest in the fight against psychiatric and neurological diseases. In the future, identified plants could be used for searching antipsychotic or neuroprotective compounds.

    Full Text Available Le développement du trekking au Népal a suscité des inquiétudes qui ont abouti à la création d’aires protégées sur la foi d’un scénario de crise environnementale dont les touristes et les paysans étaient jugés responsables. Devant les conflits entre la conservation et les nécessités de développement des régions concernées, la gouvernance des aires protégées a évolué dans le sens d’une meilleure prise en compte des sociétés locales. Pour autant les mesures prises ne font qu’accompagner et diriger des dynamiques touristiques plus anciennes qui s’exercent à des échelles plus vastes. Le trekking constitue ainsi un système touristique très largement aux mains des sociétés montagnardes du pays qui a permis l’amélioration de leurs conditions de vie tout en limitant ses impacts environnementaux. En ce sens le trekking répond assez largement aux principes du développement durable.Against a backdrop of environmental crisis, attributed to the impact of tourism and the practices of rural populations, Nepal has created protected areas with a view to preserving the Himalayan environment and promoting sustainable tourism in the regions concerned. Given the conflicts between conservation needs and development needs, local communities are now being given a bigger role in the governance of these protected areas. Yet the measures being taken simply accompany and guide well-established tourism dynamics that operate on a much greater scale. Trekking is thus a tourism system largely in the hands of the country’s mountain communities and is an activity that has enabled these communities to improve their living conditions while at the same time limiting environmental impacts. In this sense it is very much in line with the principles of sustainable development.

    2002-04-01

    Within the framework of a feasibility study of underground radioactive waste repository the experimental characterization of the coupled behavior of the host layer is of first importance. This work concerns the experimental characterization in laboratory of the poro-elastic behavior of argillite which constitutes the host layer of the future underground laboratory of ANDRA located at the limit of the Meuse/Haute-Marne. The theoretical approach is the Mechanics of Porous Media defined by Coussy [1991] which has the advantage of providing a formulation of the behavior laws using measurable parameters in laboratory. The difficulties or the feasibility of the characterization tests of these rocks coupled behavior are related to their very low permeability which requires an adaptation of the experimental devices initially used on more permeable rocks. Initially a synthesis on the knowledge of the poro-elastic parameters of Meuse/Haute-Marne argillite is given. Thereafter a first approach of the use of the studies of sensitivity as tools of decision-making aid is proposed. The experimental difficulties encountered by the various experimenters are illustrated by the diversity of the experimental choices, the test duration or by the results disparity. Because of economic, political and ecological stake, the studies of sensitivity could make it possible to direct the experimental efforts by giving indications on the dominating parameters in the coupled behavior of a rock. In the second time after the presentation of the test results of physical characterization 3 types of tests are described: permeability test (pulse test), determination of Biot coefficient under odometric loading and isotropic drained test. The complexity of these tests is related to the attack of the experimental limits. They are presented in detail: theoretical recalls, experimental set up, experimental protocol, unfolding and test results. (author)

    The 16 uranium deposits of the Crouzille (Haute-Vienne, France) have produced 25000 tons of uranium between 1950 and 1995. The uranium content of the ores ranges from 1 to 10/1000. The main production came from the underground exploitation up to 300 m of depth. This book presents the historical aspects of this industrial and human epopee and describes with details the underground exploitation of the ore, its processing and the rehabilitation of the site after the mines have closed down.

  19. Combining functional weed ecology and crop stable isotope ratios to identify cultivation intensity: a comparison of cereal production regimes in Haute Provence, France and Asturias, Spain.

    This investigation combines two independent methods of identifying crop growing conditions and husbandry practices-functional weed ecology and crop stable carbon and nitrogen isotope analysis-in order to assess their potential for inferring the intensity of past cereal production systems using archaeobotanical assemblages. Present-day organic cereal farming in Haute Provence, France features crop varieties adapted to low-nutrient soils managed through crop rotation, with little to no manuring. Weed quadrat survey of 60 crop field transects in this region revealed that floristic variation primarily reflects geographical differences. Functional ecological weed data clearly distinguish the Provence fields from those surveyed in a previous study of intensively managed spelt wheat in Asturias, north-western Spain: as expected, weed ecological data reflect higher soil fertility and disturbance in Asturias. Similarly, crop stable nitrogen isotope values distinguish between intensive manuring in Asturias and long-term cultivation with minimal manuring in Haute Provence. The new model of cereal cultivation intensity based on weed ecology and crop isotope values in Haute Provence and Asturias was tested through application to two other present-day regimes, successfully identifying a high-intensity regime in the Sighisoara region, Romania, and low-intensity production in Kastamonu, Turkey. Application of this new model to Neolithic archaeobotanical assemblages in central Europe suggests that early farming tended to be intensive, and likely incorporated manuring, but also exhibited considerable variation, providing a finer grained understanding of cultivation intensity than previously available.

    A first report proposes an analysis of the situation of methanization installations in the Haute-Normandie region while recalling the national context. It briefly reports an analysis and assessment of waste flows, processed effluents, by-products and biomass displaying an energetic potential. It describes methanization installations by addressing the different steps of the methanization process, by presenting the different digestion indicators, by briefly evoking the issue of the return-to-soil of digestates, and by presenting various operational data. Financial aspects are then addressed (investments and subsidies, financial balance of farm-based and collective installations), and an overview of methanization projects in the region and development perspectives is proposed. The second report more precisely analyses development perspectives for the methanization sector in the region through a brief assessment of the methanizable organic substrate resource, a discussion of different associated challenges (energy, agronomic, environmental and societal), a discussion of development levers and brakes, and an analysis of competitions (related to the use of industrial by-products, between processing installations, and related to agricultural soils). Another document proposes an overview of various aspects of methanization: a tool for territorial development, regulatory framework, evolution of installations in the region, assets of methanization, and role of the regional commission of expertise on methanization

    We have shown the existence and made a study of the current oscillations produced in high-resistivity gallium arsenide by a strong electric field. The oscillations are associated with the slow travelling of a region of high electrical field across the whole sample. An experimental study of the properties of these instabilities has made it possible for us to distinguish this phenomenon from the Gunn effect, from acoustic-electric effects and from contact effects. In order to account for this type of instability, a differential trapping mechanism involving repulsive impurities is proposed; this mechanism can reduce the concentration of charge carriers in the conduction band at strong electrical fields and can lead to the production of a high-field domain. By developing this model qualitatively we have been able to account for all the properties of high-resistance gallium arsenide crystals subjected to a strong electrical field: increase of the Hall constant, existence of a voltage threshold for these oscillations, production of domains of high field, low rate of propagation of these domains, and finally the possibility of inverting the direction of the propagation of the domain without destroying the latter. A quantitative development of the model makes it possible to calculate the various characteristic parameters of these instabilities. Comparison with experiment shows that there is a good agreement, the small deviations coming especially from the lack of knowledge concerning transport properties in gallium arsenide subjected to high fields. From a study of this model, it appears that the instability phenomenon can occur over a wide range of repulsive centre concentrations, and also for a large range of resistivities. This is the reason why it appears systematically in gallium arsenide of medium and high resistivity.

    Au cours de la derniere decennie, les modes de la gouvernance ont pris place dans un contexte totalement different de celui qu'ils avaient auparavant. Les gouvernements modernes se rendent compte qu'ils perdent de plus en plus leur capacite a elaborer et a gerer les changements d'une maniere autonome. Ainsi, les fonctions et les activites traditionnellement accomplies exclusivement par le gouvernement engagent de nos jours une gamme d'acteurs etatiques et non etatiques. A l'encontre du concept traditionnel de l'Etat controleur, la gouvernance contemporaine est ainsi devenue moins une question d'offre de service et davantage une gestion indirecte des reseaux de politique publique. Dans cette entreprise, les gouvernements contemporains, cherchant plus d'information, de soutien et de legitimite en matiere de formulation des decisions, ont besoin d'etablir des relations avec les divers groupes d'interet qui, a leur tour, voulaient plus de promotion et de protection en faveur de leurs interets a travers leur implication au processus de l'elaboration et de la mise en oeuvre des politiques publiques. Ainsi, l'approche des reseaux de politique publique represente aujourd'hui un courant considerable au sein du champ d'analyse des politiques publiques. Toutefois, les preoccupations des chercheurs pour cette approche, dans le domaine des politiques energetiques a des fins environnementales, semblent recentes, et les etudes realisees sont encore trop peu nombreuses.

    Full Text Available Confined to parks and forests, nature in French urban areas has been used as an instrument for urban planners and developers. Recent urban projects have sought to give natural systems a fuller role in territorial development. This new function can be considered a radically new approach. At the same time, current redevelopment projects must also integrate existing facilities. The redevelopment of the banks of the Seine by the Hauts-de-Seine council is a good example of this new role that nature can play in urban revitalisation. Maps show the constraints and issues that must be taken into account.

Ce poste ne doit pas être négligé par les entreprises : réduction à la source, recherche de filières pérennes, valorisation énergétique ou matière sont des éléments permettant également une réduction significative des coûts. La maîtrise de la consommation d’énergie est un élément important, voir stratégique, notamment dans le secteur de la trituration des graines oléagineuses. Des actions de sensibilisation permettent de poursuivre également l’effort auprès des PME, actuellement moins impliquées.

    Roozendael, M. Van; de Mazière, M.; Fayt, C.; Hendrick, F.; Hermans, C.

    Since December 2000, a ground-based off-axis DOAS spectrometer has been operated by BIRA-IASB in the South of France at the Observatoire de Haute Provence (OHP, 44°N). The design of the instrument allows automated observations of the scattered light alternatively in the zenith direction and at 10° above the horizon (off-axis geometry). The spectrometer is polarised and follows the azimuth of the sun. Its temperature is regulated and it is equipped with a Princeton Instruments/ Hammamatsu cooled diode array detector. Observations are made every 5 minutes in the 320-390 nm range. The analysis of the spectra recorded between January and December 2001 demonstrates the sensitivity of the measurements to tropospheric contents of NO2, HCHO, O3 and BrO. Results show a large seasonality in the HCHO content with maximum values in summer. The tropospheric BrO column is found to be stable over the year in the range of approximately 1.5-2 x1013 molec/cm2, roughly consistent with GOME observations at Northern mid-latitudes. Large increases of the BrO concentration are observed in summer likely due to local pollution in the vicinity of the station.

    On August 3, 1999, the French government gave the permission to the national agency of radioactive wastes (ANDRA) to build up a research laboratory devoted to the feasibility study of a facility for the reversible disposal of high level and long living radioactive wastes in deep geologic beds. The site retained is located at Bure, at the boundary of the Meuse and Haute-Marne departements. Before starting the construction of this research facility, the ANDRA has carried out a careful survey of the initial environmental status of the site which will serve as a reference. This brochure presents the results of this survey: geo-morphology, agriculture, natural ecosystems, radioecology, sound levels, air quality, surface and groundwater quality. The ANDRA has implemented an environmental monitoring plan for each phase of the development of the project. (J.S.)

Il est montré que l'on rencontre de sérieux problèmes à haute pression dans le cas où l'on utilise des coefficients d'interaction extrapolés. Les prévisions des pressions de saturation des gaz à condensats sont plus satisfaisantes lorsque les paramètres d'interaction binaire sont obtenus à partir d'une corrélation des points de rosée à haute pression. Les prévisions concernant les volumes et les compositions sont remarquables à condition que l'on définisse les paramètres des équations d'état sur la base des données ELV binaires. Des résultats contradictoires sont obtenus avec différentes méthodes dans l'estimation des propriétés critiques des hydrocarbures de poids moléculaires élevés.

    Andra is exploring several options for the disposal of low-level long-lived waste (LLW-LL). With the French Government's approval, in June 2008 Andra began looking around France for a site to build an LLW-LL repository. In late 2008 it provided the Government with a report analysing the geological, environmental and socio-economic aspects of the forty odd municipalities that expressed an interest in the project. After the withdrawal of the two municipalities chosen in 2009 to conduct geological investigations, the government asked Andra to re-explore the various management options for graphite and radium-bearing waste, focusing in particular on ways to manage these types of waste separately. The High Committee for Transparency and Information on Nuclear Safety (HCTISN) created a working group to provide feedback on the search for a site for LLW-LL. Andra submitted a report to the Government in late 2012. This report contains proposals for continuing the search and draw in particular on the HCTISN's recommendations.

    Primär kutane B-Zell-Lymphome (PCBCL) beschreiben reifzellige lymphoproliferative Erkrankungen der B-Zell-Reihe, die primär die Haut betreffen. Die Biologie und der klinische Verlauf der einzelnen PCBCL-Subtypen variieren untereinander stark und unterscheiden sich grundsätzlich von primär nodalen und systemischen B-Zell-Lymphomen. Primär kutane Marginalzonenlymphome (PCMZL) und primäre kutane follikuläre Keimzentrumslymphome (PCFCL) werden auf Grund ihres unkomplizierten Verlaufs und ihrer exzellenten Prognose zu den indolenten PCBCL gezählt. Demgegenüber stellen die diffus großzelligen B-Zell-Lymphome, hauptsächlich vom Beintyp (DLBCL, LT) die aggressiveren PCBCL-Varianten mit schlechterer Prognose dar. Für die Ausbreitungsdiagnostik und die Therapieentscheidung sind eine genaue histologische und immunhistochemische Klassifizierung sowie der Ausschluss einer systemischen Beteiligung in Abgrenzung zu nodalen oder systemischen Lymphomen notwendig. Die Diagnostik sollte dabei durch molekularbiologische Untersuchungen unterstützt werden. Therapeutisch stehen für die indolenten PCBCL primär operative und radioonkologische Maßnahmen im Vordergrund sowie eine Systemtherapie mit dem CD20-Antikörper Rituximab bei disseminiertem Befall. Die aggressiveren Varianten sollten in erster Linie mit Kombinationen aus Rituximab und Polychemotherapieschemata wie z. B. dem CHOP-Schema oder Modifikationen davon behandelt werden. Auf Grund der in allen seinen Einzelheiten noch nicht vollständig verstandenen Pathogenese und Biologie sowie des begrenzten Therapiespektrums der PCBCL besteht hier, speziell beim DLBCL, LT, noch erheblicher Forschungsbedarf. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

    Full Text Available Landscapes Prospective Modeling of the landscapes of the Haut Sassandra Classified Forest (Côte d'Ivoire After the End of The Conflicts. It has been demonstrated that armed conflicts cause biodiversity's degradation, especially in its ecosystemic and specific dimensions. The Haut Sassandra Classified Forest is an interesting case study for this kind of process. Indeed, during the conflicts, a massive migrants infiltration caused a forest cover decline and a plant diversity loss. We created a multi-agent system able to simulate the actors' movements and behaviors. The social simulation generates scenario in the form of clearing maps in classified forest. This model was first conceived as a retro-prospective model in order to test hypotheses on the social dynamics underlying this process, after having worked on its accuracy by confronting reality. This model being validated, the aim of this paper is to present a prospective modeling to illustrate, in terms of forest cover's conservation, the possible consequences of different demographic and political scenarios. Across a geoprospective logic, two scenarios are mentioned such as the continuation of conflict period trends and a proposition of ecological restoration.

    Summary Les accidents électriques par haute tension (AEHT) provoquent des brûlures profondes par effet Joule le long des axes vasculo-nerveux entre les points d'entrée et de sortie, qui sont le siège de lésions délabrantes. Les Auteurs rapportent une série de dix cas d'AEHT admis au service de chirurgie réparatrice et de brûlés de l'Hôpital Ibn Sina de Rabat à travers laquelle ils étudient les caractéristiques épidémiologiques, cliniques et thérapeutiques. Tous les patients étaient des adultes de sexe masculin dont l'âge moyen était de 31 ans. Dans 70% des cas, ces brûlures étaient secondaires à un contact avec les distributeurs d'électricité avec une surface brûlée inférieure à 20%. Le traitement des lésions électrothermiques a nécessité des interventions itératives avec amputation des segments de membres nécrosés dans 70% des cas, dont les suites étaient marquées par des séquelles fonctionnelles invalidantes. La prévention des AEHT, en particulier pour les accidents du travail au sein des professions exposées, reste fondamentale. PMID:21991124

    The first part of this research thesis addresses the theory of high frequency discharge in gases under low pressures, and first proposes a calculation of the distribution function for electrons present within the gas. The author then studies the evolution of electron density within a discharge tube by assigning the governing role in electron multiplication to the secondary emission of tube walls. The second part proposes a detailed description of a source operating at 96.5 Mc/s, a discussion of measurements performed on this source, and the search for a theoretical explanation of some of its properties. The author then briefly analyses various existing types of high frequency sources, and finally discusses their use in corpuscular microscopy and in particle accelerators [French] La presente these comprend deux parties. La premiere est consacree a la theorie de la decharge haute frequence dans les gaz aux faibles pressions et comporte tout d'abord le calcul de la fonction de distribution des electrons presents au sein du gaz. Nous etudions ensuite l'evolution de la densite electronique a l'interieur d'un tube a decharge en attribuant, a l'emission secondaire des parois de ce dernier, le role essentiel dans la multiplicalion des electrons. Nous obtenons ainsi les conditions d'amorcage. Tout au long de cette etude, on doit distinguer soigneusement le cas ou le libre parcours moyen des electrons dans le gaz est inferieur aux dimensions de l'enceinte et le cas ou il leur est superieur. La deuxieme partie comprend la description detaillee d'une source fonctionnant sur 96.5 Mc/s, l'expose des mesures effectuees sur celle-ci et la recherche d'une explication theorique de certaines de ses proprietes. Nous faisons ensuite une breve analyse des divers types de sources d'ions haute frequence existant a l'heure actuelle et nous terminons en traitant de leur utilisation en microscopie corpusculaire et dans les accelerateurs de particules.

Suivie d’une étude préliminaire, ayant pour objectif d’optimiser le dosage en Superplastifiant (0,65-1% et du ciment (500-700 kg/m3 en se basant sur des essais de résistance à la compression (3, 7, 28 jours et des mesures d’ouvrabilité. Les caractéristiques mécaniques ainsi que la porosité du BHP optimale ont été mesurées. Ainsi, l’effet d’une nouvelle génération de superplastifiant, qui a permis la réduction du rapport E/C à 0,29, a pu être examiné. Ce dernier a permis l’obtention d’un BHP de bonne performance mécanique et de faible porosité. La méthodologie proposée a permis, à ce stade de l’étude, de formuler des bons BHP et reste à ajuster et à compléter pour la formulation des BFHP.

    Using structural evolution data and a method permitting the calculation of elastic constants and Grüneisen parameters, the thermal expansion of two high T_c superconductors is interpreted. It is shown that the superconductors YBaCuO (123) and BiSrCaCuO (2212) present strongly different elastic and anharmonic properties. En appliquant une méthode déjà mise au point sur d'autres composés (Gavarri, 1981), l'évolution structurale de deux supraconducteurs à haute T_c est interprétée par le biais de leurs compressibilités anisotropes et de leurs coefficients de Grüneisen, obtenus par diffraction de neutrons et de rayons X. On montre ici que les supraconducteurs YBaCuO (123) et BiSrCaCuO (2212) diffèrent considérablement par leurs compressibilités anisotropes et par leurs coefficients de Grüneisen.

    Full Text Available La première partie de cette étude a consisté à observer et à tenter d'interpréter l'action des conditions de fonctionnement et des paramètres de réglage du moteur sur la tendance au cliquetis à haut régime. On a montré ensuite que les différentes familles chimiques d'hydrocarbures qui constituent les carburants classiques présentent chacune un comportement bien distinct en fonction de la richesse, de la pression et de la température d'admission. On a également étudié l'influence de la teneur en plomb du carburant et du type d'alkyle de plomb employé. Quelques expériences ont été effectuées afin de déterminer l'incidence d'une réduction de un point de taux de compression sur l'exigence en octane à haut régime et sur l'action des caractéristiques de composition du carburant. Enfin, en déterminant le pourcentage de cycles soumis au cliquetis pour différentes avances à l'allumage, il a été possible de fournir quelques indications permettant de mieux caractériser l'intensité du phénomène. The first part of this study consists in observing and trying to interpret the effect of operating conditions and engine tuning parameters on the tendency for high-speed knocking to appear. The different chemical families of the hydrocarbons making up conventional fuels are shown to each have a quite different behavior depending on the fuel-air equivalency ratio and the admission pressure and temperature. The influence of the lead content in the fuel and of the type of lead alkyl used is also studied. Some experiments were performed to determine the influence of a one-point reduction in the compression ratio on the high-speed octane requirement and on the effect of fuel composition properties. Lastly, by determing the percentage of cycles accompanied by knocking at different spark advances, some indications were found for better characterizing the intensity of the phenomenon.

    In front of increase of conflicts finding big environmental projects, approval of social players quickly became an essential condition in their realization, raising social acceptability to rank of priorities. To illustrate my search on social acceptability, I chose to study project of presence of an industrial wind farm on municipalities of Allas Bocage and Nieul-le-Virouil in Haute Saintonge. Methodology rests on participating observation which authorizes understanding of a group. If the social acceptability is a fragile and slow process to be built, the social unacceptability takes root durably. My problem rests on the process of construction of the social unacceptability, fruit of a different logic between promoter and local actors. My results allow me to highlight the processual dimension of the social unacceptability of one project. (author)

    Columnar defects can be introduced in high T_c superconductors by irradiation with high energy heavy ions. The concentration of these artificial pinning centers with a well characterized morphology is easily controlled. The pinning efficiency of these defects has been often demonstrated, mainly from magnetization measurements. In the present work, measurements of the electrical resistance along the c axis, R_c(T), in the presence of columnar defects are presented. They show the ability of these defects to prevent the thermal fluctuations effects. The measurements have been performed on the same crystal before and after the heavy ion irradiation. L'irradiation aux ions lourds de haute énergie permet d'introduire des défauts colonnaires amorphes dans les supraconducteurs à haute T_c. Ces centres de pinning artificiel, de morphologie connue, sont introduits en concentration facile à maîtriser. L'efficacité de ces défauts a été très souvent démontrée à partir de mesures d'aimantation. L'étude présentée ici : mesure de la résistance selon l'axe c, R_c(T), en présence de défauts colonnaires parallèles à l'axe c, montre que ces défauts sont capables de s'opposer efficacement à l'effet des fluctuations thermiques. Les mesures ont été faites sur le même monocristal avant et après l'irradiation.

On connait l'interet qu'il y a a garder dans un circuit de reacteur de l'eau de tres haute resistivite (plusieurs centaines a quelques millions {omega}.cm): abaissement de la corrosion, abaissement du taux de radiolyse, abaissement de la radioactivite des circuits et canalisations, les elements autres que les constituants de l'eau transportes par celle-ci devenant generalement radioactifs par leur passage au coeur du reacteur. Si la circulation d'eau se fait a des temperatures inferieures a 45 deg. C, les resines echangeuses d'ions organiques utilisees en lit melange resolvent tres bien le probleme de l'epuration en continu. Par contre, pour des temperatures plus elevees surtout au-dessus de 100 deg. C, leur utilisation n'est pas possible, la degradation de ces hauts polymeres etant tres rapide. De meme, l'action des rayonnements, par exemple ceux des produits fixes par les echangeurs d'ions, detruit irremediablement les chaines organiques constituant le squelette de ces echangeurs. Nous avons donc cherche d'es composes pouvant assurer une bonne deionisation de l'eau, mais de structures telles qu'elles ne soient pas deteriorees par l'action de la temperature et des rayonnements. Nous nous sommes particulierement orientes dans trois voies: - echangeurs d'ions naturels a structure minerale (argile du type montmorillonite), - composes mineraux naturels traites pour leur conferer les proprietes d'echangeurs d'ions (charbons actives), - composes mineraux synthetiques (sels tres peu solubles, phosphate et hydroxyde de zirconium et de thorium).

  13. A study on the dynamic behavior of the Meuse/Haute-Marne argillite

    Science.gov (United States)

    Cai, M.; Kaiser, P. K.; Suorineni, F.; Su, K.

    Excavation of underground tunnels can be conducted by tunnel boring machines (TBM) or drill-and-blast. TBMs cause minimum damage to excavation walls. Blasting effects on excavation walls depend on the care with which the blasting is executed. For blast-induced damage in excavation walls, two issues have to be addressed: rate of loss of confinement (rate of excavation) and dynamic loading from wave propagation that causes both intended and unintended damage. To address these two aspects, laboratory dynamic tests were conducted for the determination of the dynamic properties of the Meuse/Haute-Marne argillite. In the present study, 17 tensile (Brazilian) and 15 compression split Hopkinson pressure bar (SHPB) tests were conducted. The test revealed that the dynamic strengths of the argillite are strain rate dependent. The average dynamic increase factors (ratio of dynamic strength to static strength) for tensile and compressive strength are about 3.3 and 2.4, respectively. A high-speed video camera was used to visualize the initiation of failure and subsequent deformation of the specimens. The direct compression specimens were found to deform and fail uniformly around the circumference of the specimen, by a spalling process. The SHPB Brazilian tests indicated that failure occurred in tension along the line of load application. Radial fractures were also observed. The test results can be used for the development of a dynamic constitutive model for the argillite for the prediction of damage in underground excavation utilizing the drill-and blast method.

    In R.F. discharges at reduced pressure a resonance can increase by an order of magnitude the intensity of the plasma R.F. electric field. The electron density of the plasma adjusts itself to keep the resonant frequency equal to the excitation frequency. This behaviour has been observed by an electron beam technique. When such a discharge is excited in electronegative gases, the negative ion density may be higher than the electron density. Therefore, the D.C. potential distribution in plasma and sheath is modified. The plasma appears as a luminous body isolated from the walls by a large sheath (R.F. plasmoid).

    Full Text Available Ce papier traite de la modélisation de joints collés pour les structures soumises à des sollicitations de type crash. Cette nouvelle modélisation basée sur un élément cohésif tient compte du comportement viscoplastique, de l'endommagement ainsi que de la rupture de l'adhésive. Sensible à la vitesse de déformation l'identification du critère de rupture nécessite une base expérimentale allant jusqu'à de très hautes vitesses de déformations. Un nouveau dispositif d'essais a donc été mis en place sur les barres de Hopkinson afin de solliciter des assemblages à haute vitesse et sous différents angles de chargement. This paper deals with the modeling of bonded joints for structures subjected to dynamic crash loading. This new model based on a cohesive element takes into account the viscoelastic behavior, the damage and the failure of the adhesive. Due to the strain rate sensitivity, the identification of failure criterion requires experimental tests, up to very high strain rates. A new testing device has then been set up on the Hopkinson bar in order to load the assemblies with high strain rates and with different angles.

    A heating experiment named TER is being conducted with the objectives to identify the thermal properties, as well as to enhance the knowledge on THM processes in the Callovo-Oxfordian clay at the Meuse/Haute Marne Underground Research Laboratory (France). The in situ experiment has being switched on from early 2006. The heater, 3 m length, is designed to inject the power in the undisturbed zone at 6 m from the gallery wall. A heater packer is inflated in a metallic tubing. During the experiment, numerous sensors are emplaced in the surrounding rock and are experienced to monitor the evolution in temperature, pore-water pressure and deformation. The models and numerical codes applied should be validated by comparing the modeling results with the measurements. In parallel, some lab testing have been achieved in order to compare the results given with two different scales (cm up to meter scale). In this paper, we present a general description of the TER experiment with installation of the heater equipment and the surrounding instrumentation. Details of the in situ measurements of temperature, pore-pressure and strain evolutions are given for the several heating and cooling phases. The thermal conductivity and some predominant parameters in THM processes (as linear thermal expansion coefficient and permeability) will be discussed. (authors)

    Full Text Available In the central High Atlas of Morocco, the Liassic series present different mud-moundtype carbonate buildups, well developed in the Midelt area, towards the boundary between the Lower and the Upper Sinemurian. Near Foum Tillicht, these structures show a real evolution within the Upper Sinemunan interval, from simple small-scale bodies at the base, up to big and complex forms at the top. Their sedimentological and palaeontological features indicate microbolites and sponge buildings developed in deep and open marine conditions, within the subphotic zone, at the lower part of the storm wave interval. These buildups are closely linked to tectonic processes as they grow on the normal synsedimentary faults which affected the central atlasic area during the Lower Liassic period, leading to the breakup of the Early Sinemurian carbonate platform and the induced installation of the Upper Sinemurian subsiding basin. Silting by hemipelagic sediments led to death of buildings. Similar palaeogeographic changes and geodynamic evolution have been recently described from different structures in North Africa, Western Europe and North America.Le Lías du Haut Atlas central marocain présente diverses"bioconstructions carbonatées de type Mud-mound bien développées au passage Sinémurien inférieur- Sinémurien supérieur au Sud de Midelt.

Se observa una correlación clara entre nivel de riqueza y de calidad ambiental para los países cristianos, que no es tan evidente en los hindúes o musulmanes. A similar nivel de riqueza y población, los países cristianos de hecho ofrecen valores más altos de calidad ambiental que los encontrados en países con otras tradiciones religiosas. Si bien de nuestro análisis no puede concluirse que el cristianismo promueva la conservación ambiental, los resultados indican al menos que puede rechazarse la hipótesis contraria, ya que los países cristianos no presentan indicadores significativamente peores que los encontrados en países representativos de otras tradiciones religiosas.

    A crystallization age of 432sub(-10)/sup +20/Ma has been determined for the 'La Borie' eclogite (Haut-Allier, France), by U-Pb dating on zircons. This age is yielded by the upper intercept with the Concordia curve. In agreement with recent dates obtained in the southern part of the Massif Central, in Brittany and in Vendee, these data indicate that the high-pressure/high-temperature-metamorphic phase representative of the pre-Variscan evolution of the western Europe, took place at the Silurian/Ordovician boundary. This high-pressure/high-temperature metamorphism could be significant of subduction processes more or less synchronous, preceeding the main continental collision responsible of the Variscan belt.

    Document available in extended abstract form only. The Paris Basin system covers approximately 200 000 km 2 and consists of 27 aquiferous and semipermeable (aquitard) hydrogeological units of Trias to Quaternary age that are intersected by 80 regional faults. The Meuse/Haute-Marne site is located in the eastern part of the Paris Basin and covers approximately 250 km 2 . Within the sector, the Callovo-Oxfordian clay formation is a potential host for the French high and intermediate level and long lived radioactive waste. It is located at a mean depth of 500 m and has a minimum thickness of 130 m and very low hydraulic conductivity, on the order of 10-14 m/s. The Callovo-Oxfordian is confined between the overlying Oxfordian aquifer and the underlying Dogger aquifer. Both the Oxfordian and Dogger are limestone aquifers characterized locally by macro-pores, regional faults that oriented along the N40 deg. E direction (the Gondrecourt and Joinville faults) and the N150 deg. E direction (the Marne and Poissons faults), as well as diffuse fracture zones located south west of the Meuse/Haute-Marne Repository site. To support site investigation of the Meuse/Haute-Marne underground repository, a single continuum multi-scale hydrogeological model of the Paris Basin and the Meuse/Haute-Marne sector has been developed. The model represents 27 hydrogeological units at the scale of the Paris Basin, and it is refined at the scale of the sector to represent 27 different layers that range in age from the Trias to the Portlandian. The model has been calibrated to observed hydraulic heads by varying the hydraulic conductivity of the individual layers, using a single continuum approach. To investigate the impact of treating the two confining layers for the clay formation, the Oxfordian and Dogger aquifers, as single continua with equivalent hydraulic properties for the combined fracture and matrix system, additional simulations have been conducted with either a dual continuum or

    Full Text Available Water vapor total column measurements at Observatoire de Haute Provence (5°42´ E, +43°55´ N, south of France, were obtained using observations of astronomical objects made between July 1994 and December 2004 on the 193-cm telescope with the high-resolution spectrometer Elodie. Spectra of stars, nebulae, and other astronomical objects were taken regularly during 10 years. More than 18 000 spectra from 400 nm to 680 nm are available on-line in the Elodie Archive. This archive, usually explored by astronomers, contains information to study the atmosphere of the Earth. Water vapor absorption lines appear in the visible in delimited bands that astronomers often avoid for their spectral analysis. We used the Elodie Archive with two objectives: firstly, to retrieve seasonal variability and long-term trend of atmospheric water vapor, and secondly, to remove signatures in spectra for further astronomical or geophysical use. The tools presented here (the workflow, the interoperable Elodie Archive and the web service Tellodie are developed following, when possible, formats and standards recommended by the International Virtual Observatory Alliance.

    Full Text Available À Madagascar, depuis quelques années, la sauvegarde de la biodiversité est devenue une priorité pour le gouvernement. Avec l’aide des partenaires étrangers le pays étend actuellement de manière spectaculaire son réseau d’espaces protégés. Malgré l’intégration de la gouvernance participative sur le terrain, ce mouvement s’accompagne d’une très forte déstabilisation des communautés locales. Parallèlement, le pays qui affronte des crises multiples (crise économique latente et crises politiques à répétition est le théâtre d’un formidable « boum » des activités informels en général et de l’artisanat minier en particulier. Dans bien des cas, lorsque la gestion des milieux sensible est retirée aux communautés locales au profit d’acteurs institutionnels, on assiste au développement de ces activités destructrices. Pour lutter contre cet effet pervers de l’institutionnalisation de la protection environnementale, il devient urgent de disposer d’un plus large panel de systèmes de gouvernance. Ceux-ci doivent être conçus pour s’adapter aussi bien que possible à la multitude de contextes rencontrés, en prenant en compte l’ensemble des acteurs, qu’ils soient formels, issus de la société traditionnelle, ou informels.In Madagascar, during the last few years, conservation of biodiversity has become a major priority for the government.

    Following the excellent results obtained on the industrial coating of radioactive sludges, the possibility of solidifying also the evaporation concentrates with bitumen has been considered. For high activity concentrates, the use of bitumen is however limited by two main parameters: temperature resistance, irradiation resistance. By making use of the characteristics of a blown bitumen, it has been possible to design a high activity coating pilot plant treating concentrations of several tens of curies per litre. This plant will make use of a screw-type extrusion machine capable of coating treated concentrates at a rate of 20 l/hr. Before being coated, the concentrates will be subjected to a coprecipitation treatment designed to make the radioelements insoluble. This installation will make possible, apart from technological studies, laboratory experiments on the coated material (measurements on self-heating, on electrical charges, on radiolytic gases, and also lixiviation tests. It is at present believed, on the basis of available data, that it is possible to coat concentrates having an activity of 20 Ci/l at a price of 1840 F per cubic metre. (authors) [French] A la suite des excellents resultats obtenus pour l'enrobage industriel des boues radioactives, il a ete envisage de solidifier egalement les concentrats d'evaporation par le bitume. Pour les concentrats de haute activite, l'emploi du bitume est cependant limite par deux parametres essentiels: tenue a la temperature, tenue a l'irradiation. Grace aux caracteristiques d'un bitume souffle, il a ete possible de concevoir une installation pilote d'enrobage haute activite contenant plusieurs dizaines de curies par litre. Cette installation utilisera une machine du type extrudeuse a vis qui peut enrober 20 l/h de concentrats traites. Avant leur enrobage, les concentrats subiront un traitement de coprecipitation destine a insolubiliser les radioelements. En dehors des etudes technologiques, cette installation

    The cold cathode reflex discharge develops a cathode sheath of several hundreds of volts, which accelerates electrons released from the cathode to high velocities along the lines of the axial magnetic field. On the studied pressure range (4.10{sup -4} torr < p < 2.10{sup -2} torr) the plasma density is about 10{sup 11} cm{sup -3}. Under certain conditions high frequency (1 5000 MHz) instabilities appear. These instabilities are found to profoundly modify the mean characteristics of the discharge. In particular, particle flow across the lines of magnetic field is found to be considerably greater than that predicted by classical diffusion theory. Theoretical considerations are presented with complementary experimental results. They show that the high frequency instabilities are a result of the fast electronic assembly accelerated through the cathode sheath. (author) [French] Dans certaines conditions, qui sont precisees, des instabilites a haute frequence (1 5000 MHz) se developpent dans la decharge reflex a cathodes froides. Lorsque le plasma (n {approx_equal}10{sup 11} cm{sup -3}) est instable, les caracteristiques moyennes de la decharge sont profondement alterees. Les fuites de particules a travers les lignes de forces du champ magnetique statique applique deviennent en particulier trop importantes pour que le seul effet classique des collisions binaires puisse les expliquer. L'ionisation du gaz est assuree par une assemblee electronique qui acquiert dans les gaines cathodiques ({approx_equal} 500 volts) une vitesse, parallele au champ magnetique, importante. La discussion de resultats theoriques et une experience complementaire montrent que cette population d'electrons rapides, tres distincte de celle des electrons lents du plasma pour les pressions les plus faibles du domaine etudie (4.10{sup -4} torr < p < 2.10{sup -2} torr), est responsable des instabilites a haute frequence observees.

    Full Text Available Characterization of the Spatial Urban Growth of the city of Lubumbashi (Haut-Katanga, D.R. Congo between 1989 and 2014. A quantification of the spatio-temporal dynamics of urbanization is crucial to apprehend urban morphology and its ecological effects, in order to support sustainable urban planning. This study aimed at understanding the spatial urban growth of Lubumbashi city based on the analysis of six SPOT satellites images. With the exception of the 1996-2002 period, Lubumbashi city underwent a high average annual growth rate exceeding that observed for other cities in sub-Saharan Africa. Between 1989 and 2014, the built-up percentage increased from 6 % to 20 %. Our results suggest that the urbanization of Lubumbashi city followed a complex diffusion-coalescence model. The main reason of this perturbation is the combination of the rapid demographic growth with an inappropriate urban growth management.

    For more than 50 years, more than 200 sites were prospected and mined to extract uranium in France. Haute-Vienne, in the Midwest of the country, played a leading position. Up to the present, rehabilitation of the sites is nearly complete and surveillance is the way of assessing its efficiency. In 2003, AREVA NC was asked to produce a report presenting the results of the ten-year (1994-2003) monitoring and surveillance of the rehabilitated sites and their environment. In 2006, the Institute of Radioprotection and Nuclear Safety (IRSN) was asked to perform the technical review of this report. This review led IRSN to recommend actions to improve the monitoring systems and minimise discharges to the environment. Results and recommendations were presented to and discussed with the pluralistic expert group (GEP) created in 2006 by the French ministries of environment, health and industry. (author)

  19. Artificial snowmaking and potential water conflicts in mountain resorts. The case of Avoriaz (Haute-Savoie, France)

    Science.gov (United States)

    Magnier, E.; Reynard, E.

    2012-04-01

    The practice of artificial snowmaking is recent (1990s), and may use large volumes of water. In the French Alps, the total consumption is on average 20 Mm3 per year (Miquel, 2003), which corresponds to the annual consumption of drinking water for a city of more than 300,000 inhabitants such as Nice (France). Moreover, snowmaking does not represent the only use of water in winter sport resorts. The available water resource is used for drinking water, artificial snowmaking and leisure activities (swimming pools, golf spas). One can speak in this context of a multifunctionality of the resource. Of particular concern is the winter season when streams reach their lowest level (from December to April). These activities require that water is drawn from resources created at other times of the year. Water for snowmaking production is pumped from drinking water reservoirs, rivers, groundwater tables, artificial hydropower reservoirs, as well as from hill water reservoirs, specifically built for storing water for snow production, themselves supplied from surface water capture. In Avoriaz (Haute-Savoie, France) the risk of shortages is important. The reason is that the resort is supplied by a unique lake or hillside reservoir (Lake 1730), which satisfies two particularly high-consuming water uses (the water supply for production of snow and drinking water). On a finer scale, namely that of a single day in January 2011, considerable volumes are drawn off in the space of a few hours (10,114 m3 on 24 January), while pumping for drinking water spreads out over several months. Intensity of use for the production of snow can trigger water scarcity and water conflicts with other uses such as drinking water. Good management of the resource is, therefore, especially important. However, no legislation specific to artificial snowmaking has been established. Even if, at present, there is no situation involving shortages and conflicting uses at Avoriaz, the situation needs to be monitored

    Document available in extended abstract form only. A clay-stone formation of Callovo-Oxfordian age is found throughout the multilayered sedimentary fill of the Paris Basin. It is considered as a potential host rock for France's high and intermediate-level long-lived radioactive waste. The Callovo-Oxfordian layer is located between an overlying limestone of Oxfordian age and an underlying limestone of Dogger age.. The Meuse/Haute-Marne sector area is located in the East of France, the area includes the Bure investigation site and a domain referred to as the 'transposition zone' selected as a suitable location for France's high- and intermediate-level long-lived radioactive waste The objective of the study was to estimate how the groundwater flow in the Meuse/Haute- Marne aquifer system will change because of the geomorphologic evolution over the next 1 million of years. The future groundwater flows and the future evolution of the vertical hydraulic gradient in the transposition zone are of importance in the performance assessment and the safety analysis of a future repository for radioactive waste. The study is based on numerical modelling and the established model covers the whole of the Paris basin. The studied time period corresponds to 1 million years into the future. The initial geometry of geological layers as well as the conductivity and the porosity of the layers are input data to model, and defined by the single-continuum multi-scale hydrogeological model of the Paris Basin and the Meuse/Haute-Marne Sector area as developed by Andra. A description of the transient geomorphologic evolution was used as input data to the groundwater flow modelling. The description include: (i) The deformation of the geological layers as a result of a non-symmetric tectonic uplift of the Paris basin and (ii) The movement of the topography because of mechanical erosion along valleys, chemical erosion along plateaus and sedimentation along valleys.

    Baechler, S.; Lavanchy, J. M.; Armand, G.; Cruchaudet, M.

    In order to investigate potential changes of the hydraulic properties of the EDZ over time in the Meuse/Haute-Marne underground research laboratory (URL), several hydraulic tests campaigns have been carried out between 2005 and 2008 in dedicated boreholes. After several test series, inconsistencies were noticed in the results, indicating, in particular cases, erratic, inexplicable property changes over time and spatial contrasts. It was therefore difficult to determine reliably potential trends of the EDZ hydraulic properties. It appeared necessary to re-evaluate both the interpretation concepts and assumptions applied to the numerical analyses of test data on the EDZ, trying to better constrain the flow model and the parameter variables. In order to improve the understanding of the geometrical, geomechanical and hydraulic properties of the EDZ, independent information from other investigation methods has been used to critically revise the conceptual model and formation parameters. In particular, results from a diffusion experiment and ultrasonic measurements allowed constraining the extent of the mechanical damaged zone around the borehole (BDZ). Storativity parameters were fitted due to their expected variability. Indeed, high storativity values can be presumed under the unsaturated conditions of the EDZ. The results of the reanalyses, performed with the numerical borehole simulator MULTISIM, demonstrated the good quality and consistency of the revised conceptual model with constrained BDZ and variable storativity. Overall the new simulation results obtained from selected test series are now very consistent. The revised conceptual model demonstrated its capacity to better represent the evolution and extension of the EDZ around a drift in Meuse/Haute-Marne URL. Further consistency checks are proposed to confirm the new model assumptions and the estimates of the single phase flow model in the EDZ.

Storativity parameters were fitted due to their expected variability. Indeed, high storativity values can be presumed under the unsaturated conditions of the EDZ. The results of the reanalyses, performed with the numerical borehole simulator MULTISIM, demonstrated the good quality and consistency of the revised conceptual model with constrained BDZ and variable storativity. Overall the new simulation results obtained from selected test series are now very consistent. The revised conceptual model demonstrated its capacity to better represent the evolution and extension of the EDZ around a drift in Meuse/Haute-Marne URL. Further consistency checks are proposed to confirm the new model assumptions and the estimates of the single phase flow model in the EDZ. (authors)

    Full Text Available Les entreprises sont de plus en plus appelées aujourd’hui à prendre en considération les aspects environnementaux dans leur gestion. Elles sont la cible des pressions environnementales dont la principale source est les pouvoirs publics. Ainsi, le présent papier se propose d’étudier la nature de la relation entre les entreprises et les pouvoirs publics en matière de protection de l’environnement. Afin d’atteindre cet objectif, une étude de cas est effectuée sur 8 entreprises tunisiennes dont deux sont certifiées par la norme ISO 14001. Les résultats montrent que toutes les entreprises ont fait l’objet d’inspections périodiques et de pénalités de la part des pouvoirs publics qui constituent la principale et parfois l’unique source de pression environnementale dans le contexte tunisien. Ces entreprises trouvent que les normes législatives environnementales sont difficiles à atteindre. Aussi, les résultats identifient deux types de relations entre les entreprises et les pouvoirs publics : coopérative et conflictuelle. De même, l’étude de cas montre que les pressions environnementales ont diminué suite aux actions environnementales effectuées mais demeurent toujours présentes.Companies are today more and more called to consider the ecological aspects in their management. They are the target of the ecological pressures the main source of which is public authorities.

To reach this objective, a case study is made on 8 Tunisian companies among which two are certified to the standard ISO 14001. The results show that public authorities (constitute the most and sometimes the only source of ecological pressure in the Tunisian context. These pressures show themselves by overhauls and penalties.

    Full Text Available Qualitative computing has been part of our lives for thirty years. Today, we urgently call for an evaluation of its international impact on qualitative research. Evaluating the international impact of qualitative research and qualitative computing requires a consideration of the vast amount of qualitative research over the last decades, as well as thoughtfulness about the uneven and unequal way in which qualitative research and qualitative computing are present in different fields of study and geographical regions. To understand the international impact of qualitative computing requires evaluation of the digital divide and the huge differences between center and peripheries. The international impact of qualitative research, and, in particular qualitative computing, is the question at the heart of this array of selected papers from the "Qualitative Computing: Diverse Worlds and Research Practices Conference." In this article, we introduce the reader to the goals, motivation, and atmosphere at the conference, taking place in Istanbul, Turkey, in 2011. The dialogue generated there is still in the air, and this introduction is a call to spread that voice. URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs1202285

  14. Physical and numerical modelling of permafrost dynamic during a climatic cycle: implications for Meuse - Haute-Marne site

    International Nuclear Information System (INIS)

    Regnier, D.

    2012-01-01

    This manuscript deals about works realized on the permafrost modelling in porous media and its impact on the hydrogeological circulations. These are parts of the Andra's studies on the nuclear waste storage and, on the environmental studies of the Meuse/Haute-Marne (MHM) site. During a climatic cycle, cold periods can generate permafrost (ground with temperature lower than 0 C for 2 consecutive years). This peri-glacial structure propagates towards deep geological layers, and, due to its very low permeability, can stop the flow of water bodies like aquifers. This work presents the elaboration of two numerical models (with Cast3M code (CEA)): (i) a model with thermal conduction, used for the study of a cold wave propagation in porous media with phase transition (water-ice); (ii) a more complex model, managing the thermo-hydraulic coupling of ground phenomenon (conduction, convection and transition of phase). After validation, these two models offer three axes of development: (i) benchmark proposition by the study of two generic test-cases; (ii) study of the local air temperature signal on MHM site: importance of high frequency temperature variations (centennial scale) for permafrost depth and stability; (iii) study of the dynamics of a thermal discontinuity in a typical hydrological system river-plain: closure time of the system by the permafrost according to various parameters (temperatures, geothermal flow, hydrological flow directions).

    Conil N.

    2010-06-01

    Full Text Available Andra is in charge of studying the feasibility of a disposal facility for longlived high-level nuclear waste (LL-HLW in a deep geological environment. With this aim, dedicated experiments have been carried out for several years at the Meuse/Haute Marne Underground Research Laboratory excavated in a 500 m deep argillaceous rock formation. These experiments include determining the feasibility of the excavation of disposal cells for LL-HLW, consisting of 40 meter long, 70 cm in diameter, horizontal cased micro tunnels. The hydro mechanical impact of the excavation of such openings on the rock mass behaviour is continuously monitored as well as their mean term mechanical behaviour. Since LL-HLW produce heat, the impact of temperature on the surrounding rock mass and on the micro tunnel steel casing will also be studied. Specific instrumentation has been developed to study this impact. The first step of the microtunnel excavation tests, carried out in 2009, has led to improving the excavation method and the drilling machine. These improvements will be tested in the next step of the excavation tests planned for 2010. The THM experiment dedicated to studying the behaviour of the rock mass under thermal solicitation started early 2010. The behaviour of a steel casing in contact with the rock mass and under thermal solicitation will be studied in an experiment scheduled to start in September 2010.

    2013-07-01

    The objective of our study was to determine the trace metal accumulation rates in the Misten bog, Hautes-Fagnes, Belgium, and assess these in relation to established histories of atmospheric emissions from anthropogenic sources. To address these aims we analyzed trace metals and metalloids (Pb, Cu, Ni, As, Sb, Cr, Co, V, Cd and Zn), as well as Pb isotopes, using XRF, Q-ICP-MS and MC-ICP-MS, respectively in two 40-cm peat sections, spanning the last 600 yr. The temporal increase of metal fluxes from the inception of the Industrial Revolution to the present varies by a factor of 5-50, with peak values found between AD 1930 and 1990. A cluster analysis combined with Pb isotopic composition allows the identification of the main sources of Pb and by inference of the other metals, which indicates that coal consumption and metallurgical activities were the predominant sources of pollution during the last 600 years.

    To compare the contribution of "trial-sibling" and "unrelated" qualitative studies in complex intervention reviews. Researchers are using qualitative "trial-sibling" studies undertaken alongside trials to provide explanations to understand complex interventions. In the absence of qualitative "trial-sibling" studies, it is not known if qualitative studies "unrelated" to trials are helpful. Trials, "trial-sibling," and "unrelated" qualitative studies looking at three health system interventions were identified. We looked for similarities and differences between the two types of qualitative studies, such as participants, intervention delivery, context, study quality and reporting, and contribution to understanding trial results. Reporting was generally poor in both qualitative study types. We detected no substantial differences in participant characteristics. Interventions in qualitative "trial-sibling" studies were delivered using standardized protocols, whereas interventions in "unrelated" qualitative studies were delivered in routine care. Qualitative "trial-sibling" studies alone provided insufficient data to develop meaningful transferrable explanations beyond the trial context, and their limited focus on immediate implementation did not address all phenomena of interest. Together, "trial-sibling" and "unrelated" qualitative studies provided larger, richer data sets across contexts to better understand the phenomena of interest. Findings support inclusion of "trial-sibling" and "unrelated" qualitative studies to explore complexity in complex intervention reviews. Copyright © 2016 Elsevier Inc. All rights reserved.

Les enregistrements en champ total obtenus dans des puits fortement déviés ou horizontaux peuvent être traités pour fournir des sections de microsismique de puits qui ont une investigation latérale d'une dizaine de mètres par rapport au drain. Cet article présente les résultats d'expérimentations réalisées dans une carrière calcaire située en Bourgogne (France. Un puits fortement dévié (10 degrés a été foré dans l'unité géologique oolithe blanche qui a une épaisseur de 80 m environ. Des diagraphies acoustiques et de la sismique haute résolution ont été enregistrées dans le puits dévié. En diagraphie acoustique, deux jeux de données ont été enregistrés : une section à déport constant et un point de tir commun à très grand nombre de traces et à distance entre traces centimétrique. Le traitement des données met en évidence des réflexions internes a l'oolithe blanche situées à quelques mètres par rapport au drain. La diagraphie acoustique ne permet pas d'éclairer le toit et le mur de l'unité oolithe blanche. Cet objectif est partiellement atteint par une sismique très haute résolution de puits. Ce type de sismique travaille dans une bande de fréquences intermédiaire entre la sismique de puits classique et la diagraphie acoustique. Elle nécessite le développement d'outils particuliers, notamment au niveau des sources de puits. Une collection point de tir commun de données de sismique très haute résolution obtenues avec une source prototype de type impulsionnel montre des réflexions correspondant à des réflecteurs situés à plusieurs dizaines de mètres (~40 m par rapport au drain. Les résultats des expérimentations montrent le potentiel de la diagraphie acoustique et de la sismique haute résolution de puits à décrire une unité réservoir à différentes échelles.

    The frequency of qualitative studies in the Emergency Medicine Journal, while still low, has increased over the last few years. All take a generic approach and rarely conform to established qualitative approaches such as phenomenology, ethnography and grounded theory. This generic approach is no doubt selected for pragmatic reasons but can be weakened by a lack of rigor and understanding of qualitative research. This paper explores qualitative approaches and then focuses on “best practice” fo...

    This study follows a study realised in the late 80's by the National cancer institute to analyse the rate of cancers near american nuclear power plants (Jablon S and al, Jama 1991). The rates of mortality for the leukemia of child remain near 1 but increased in the proximity of nuclear power plants still in operation, in a statistically significant way only for old ones; they decreased in the proximity of nuclear power plants that are no more in operation. However, we must be cautious with the interpretation of these results. the question arises of an influence of environmental radioisotopes but other factors can occur ( social situation, other atmospheric pollutants, proximity of medical centers). Otherwise, the incidence of the child leukemia has very much increased these last years without any clear explanation ( =28% in Usa between 1975 and 2004). On the other hand, the rate of mortality decreased because of more efficient treatments (-49% on the same period). These findings justify to continue studies on leukemia of child in the vicinity of nuclear power plants, studies of incidences got from registers susceptible to give the most interesting results.

    Full Text Available Qualitative research in the health sciences has had to overcome many prejudices and a number of misunderstandings, but today qualitative research is as acceptable as quantitative research designs and is widely funded and published. Writing the proposal of a qualitative study, however, can be a challenging feat, due to the emergent nature of the qualitative research design and the description of the methodology as a process. Even today, many sub-standard proposals at post-graduate evaluation committees and application proposals to be considered for funding are still seen. This problem has led the researcher to develop a framework to guide the qualitative researcher in writing the proposal of a qualitative study based on the following research questions: (i What is the process of writing a qualitative research proposal? and (ii What does the structure and layout of a qualitative proposal look like? The purpose of this article is to discuss the process of writing the qualitative research proposal, as well as describe the structure and layout of a qualitative research proposal. The process of writing a qualitative research proposal is discussed with regards to the most important questions that need to be answered in your research proposal with consideration of the guidelines of being practical, being persuasive, making broader links, aiming for crystal clarity and planning before you write. While the structure of the qualitative research proposal is discussed with regards to the key sections of the proposal, namely the cover page, abstract, introduction, review of the literature, research problem and research questions, research purpose and objectives, research paradigm, research design, research method, ethical considerations, dissemination plan, budget and appendices.

Um die Hypothese, dass die Zerfallsprodukte des Radons eine wichtige Rolle bei der therapeutischen Wirkung spielen, zu ueberpruefen, sollte das Anlagerungsverhalten der Rn-Folgeprodukte untersucht werden. Nach einem Aufenthalt der Testpersonen von 20 Minuten in der Wanne wurde der Aktivitaetsverlauf an verschiedenen Punkten des Koerpers (Unterarme, Bauch, Unterschenkel) alpha-spektrometrisch gemessen. Aus den Spektren und den Zerfallskurven koennen die Aktivitaeten der einzelnen Folgeprodukte {sup 218}Po, {sup 214}Pb und {sup 214}Bi/{sup 214}Po unterschieden werden. Um den zeitlichen Verlauf der Zerfallsproduktanlagerung zu untersuchen, wurde eine Versuchsperson dem Wasser jeweils fuer 10, 20, 30, 40 und 60 Minuten ausgesetzt; danach wurde wieder der Aktivitaetsverlauf ueber 30 Minuten aufgezeichnet. Die Messungen zeigten, dass sich die Aktivitaeten der einzelnen Zerfallsprodukte auf der Haut stark unterscheiden. Einerseits scheint die Verteilung am Koerper keineswegs homogen zu sein, andererseits konnten individuelle Unterschiede zwischen den einzelnen Person beobachtet werden. So schwankten die Mittelwerte der Aktivitaeten auf der Haut zwischen 1,2 Bq/cm{sup 2} und 4,1 Bq/cm{sup 2}. Die Exposition und Messung von Kupfer- und PVC-Platten bestaetigten fruehere Ergebnisse, nach denen sich Radonzerfallsprodukte auf unbelebten Flaechen weniger stark anlagern als auf belebten. Aus der Tatsache, dass die Zerfallsprodaktivitaeten auf der Haut bemerkenswert hoch sind, erscheint ein moeglicher Zusammenhang mit der Heilwirkung seht wahrscheinlich. (orig.)

    This analysis consists of a theoretical and practical study of a high-tension electrical power generator based on the Van de Graaff generator principle, the main difference being that the charges produced are transported by a gas in motion and not by a belt. The electrical and thermal properties of such a generator are studied, as well as the difficult problem of the production of the ionised particles used in the conversion. A certain number of results already published on this process for converting kinetic energy into electrical energy is given, as well as some possible applications in the field of space technology. (author) [French] Cette analyse est une etude theorique et pratique d'un generateur de puissance electrique a haute tension, base sur le principe du generateur Van de Graaff, la difference principale etant que les charges produites sont transportees pur un gaz en mouvement et non par une courroie. Les proprietes electriques et thermiques d'un tel generateur sont etudiees ainsi que le probleme delicat de la production des particules ionisees utilisees dans la conversion. Un certain nombre de resultats publies sur ce procede de conversion d'energie cinetique en energie electrique sont reproduits, ainsi que les applications possibles aux problemes spatiaux. (auteur)

Although the appeal to consulting firms – to consultants – and in the scientific laboratories – to researchers – by the State services or local government, exists for a long time now, the partnership between consultants and researchers is recent. Even though this partnership is not systematic in urban planning, it brings a contribution with a high added value in the services, according to the public partners.

    Background Qualitative research is undertaken with randomized controlled trials of health interventions. Our aim was to explore the perceptions of researchers with experience of this endeavour to understand the added value of qualitative research to the trial in practice. Methods A telephone semi-structured interview study with 18 researchers with experience of undertaking the trial and/or the qualitative research. Results Interviewees described the added value of qualitative research for the trial, explaining how it solved problems at the pretrial stage, explained findings, and helped to increase the utility of the evidence generated by the trial. From the interviews, we identified three models of relationship of the qualitative research to the trial. In ‘the peripheral’ model, the trial was an opportunity to undertake qualitative research, with no intention that it would add value to the trial. In ‘the add-on’ model, the qualitative researcher understood the potential value of the qualitative research but it was viewed as a separate and complementary endeavour by the trial lead investigator and wider team. Interviewees described how this could limit the value of the qualitative research to the trial. Finally ‘the integral’ model played out in two ways. In ‘integral-in-theory’ studies, the lead investigator viewed the qualitative research as essential to the trial. However, in practice the qualitative research was under-resourced relative to the trial, potentially limiting its ability to add value to the trial. In ‘integral-in-practice’ studies, interviewees described how the qualitative research was planned from the beginning of the study, senior qualitative expertise was on the team from beginning to end, and staff and time were dedicated to the qualitative research. In these studies interviewees described the qualitative research adding value to the trial although this value was not necessarily visible beyond the original research team due

    From the middle to the end of the twentieth century, several thousands tons of uranium have been extracted from the ground of the French department of Haute-Vienne. These activities have not been without any environmental consequences. Water is an environmental compartment particularly vulnerable because several polluting factors may release radionuclides from 238 U chain a long time after the end of the mining activities. It has been shown that water used for drinking water fabrication for the City of Limoges, 140 000 inhabitants, and for a group of 22 communes with 20 000 inhabitants and leisure water of Saint-Pardoux lake have activities which are unusually high. A health risk quantitative assessment has been carried out. The results show for radiological risk that 226 Ra is, in the most realistic hypothesis, the main responsible for the annual effective dose; moreover, the annual effective dose are lower than the radioprotection standards and the WHO's recommendations of 0.1 mSv per year in drinking water. The results also show that it would not be pertinent to carry out an epidemiological study because of a lack of statistical power. (author)

    Full Text Available This article provides a discussion on the question of validity in qualitative evaluation. Although validity in qualitative inquiry has been widely reflected upon in the methodological literature (and is still often subject of debate, the link with evaluation research is underexplored. Elaborating on epistemological and theoretical conceptualizations by Guba and Lincoln and Creswell and Miller, the article explores aspects of validity of qualitative research with the explicit objective of connecting them with aspects of evaluation in social policy. It argues that different purposes of qualitative evaluations can be linked with different scientific paradigms and perspectives, thus transcending unproductive paradigmatic divisions as well as providing a flexible yet rigorous validity framework for researchers and reviewers of qualitative evaluations.

    Document available in extended abstract form only. Due to its low permeability (10 -18 to 10 -20 m 2 ), the Meuse-Haute/Marne argillite is chosen as the candidate host rock for the geological disposal of high-level radioactive waste by 'Agence Nationale de gestion des Dechets Radioactifs' (ANDRA). During the excavation of the underground tunnel in argillite formation, the Excavation Damaged Zone (EDZ) is expected to develop due to the stress redistribution during excavation and subsequent rock convergence. The nucleation and propagation of microcracks in EDZ can consequently affect the poro-mechanical behavior of the host rock. Therefore, it is of crucial importance to study the poro-mechanical behavior of Meuse-Haute/Marne argillite under the influence of stress induced microcracks. For this purpose, this paper presents the original experimental results of drained and undrained triaxial compression tests as well as evolution of Biot's coefficient during hydrostatic and deviatoric loading of saturated Meuse-Haute/Marne argillite. The size of samples used in the present work is 20x20 mm in order to reduce the saturating time. The axis of the cylindrical sample is perpendicular to the bedding planes. The test system is placed in an insulated room and a temperature control system is used to maintain a constant temperature of 20 ±0.2 C. The saturation condition is an important factor for the determination of the mechanical and poro-elastic properties of saturated argillite. Thus, for each sample, after putting into the triaxial cell, the confining pressure is loaded to 2 MPa and we inject distilled water both at the injection and outlet faces in order to insure the pore pressure at the two faces hold at 1 MPa. This procedure will be keep to 72 hours. Then, the pore pressure at the injection face is increased to 1.5 MPa, and we record the pore pressure at the outlet face. Once the pore pressure at the outlet face reaches the same value at injection face, the sample is

    Background Qualitative research appears to be gaining acceptability in medical journals. Yet, little is actually known about the proportion of qualitative research and factors affecting its publication. This study describes the proportion of qualitative research over a 10 year period and correlates associated with its publication. Design A quantitative longitudinal examination of the proportion of original qualitative research in 67 journals of general medicine during a 10 year period (1998–2007). The proportion of qualitative research was determined by dividing original qualitative studies published (numerator) by all original research articles published (denominator). We used a generalized estimating equations approach to assess the longitudinal association between the proportion of qualitative studies and independent variables (i.e. journals' country of publication and impact factor; editorial/methodological papers discussing qualitative research; and specific journal guidelines pertaining to qualitative research). Findings A 2.9% absolute increase and 3.4-fold relative increase in qualitative research publications occurred over a 10 year period (1.2% in 1998 vs. 4.1% in 2007). The proportion of original qualitative research was independently and significantly associated with the publication of editorial/methodological papers in the journal (b = 3.688, P = 0.012); and with qualitative research specifically mentioned in guidelines for authors (b = 6.847, Pqualitative research was associated only with journals published in the UK in comparison to other countries, yet with borderline statistical significance (b = 1.776, P = 0.075). The journals' impact factor was not associated with the publication of qualitative research.

    Full Text Available Qualitative content analysis is commonly used for analyzing qualitative data. However, few articles have examined the trustworthiness of its use in nursing science studies. The trustworthiness of qualitative content analysis is often presented by using terms such as credibility, dependability, conformability, transferability, and authenticity. This article focuses on trustworthiness based on a review of previous studies, our own experiences, and methodological textbooks. Trustworthiness was described for the main qualitative content analysis phases from data collection to reporting of the results. We concluded that it is important to scrutinize the trustworthiness of every phase of the analysis process, including the preparation, organization, and reporting of results. Together, these phases should give a reader a clear indication of the overall trustworthiness of the study. Based on our findings, we compiled a checklist for researchers attempting to improve the trustworthiness of a content analysis study. The discussion in this article helps to clarify how content analysis should be reported in a valid and understandable manner, which would be of particular benefit to reviewers of scientific articles. Furthermore, we discuss that it is often difficult to evaluate the trustworthiness of qualitative content analysis studies because of defective data collection method description and/or analysis description.

    Document available in extended abstract form only. Within its scientific program to study the feasibility of a high level radioactive waste disposal in the Callovo-Oxfordian argillaceous rock (COx) of the eastern Paris Basin, Andra has conducted an extensive characterization of the Oxfordian and Dogger limestone formations above and below the COx. More than 35 wells ranging from 400 to 700 meters deep were drilled over 15 years to study a 400 km 2 area around the Andra's Meuse / Haute-Marne Underground Research Laboratory (URL). An original methodology was applied in these wells to characterize the geology, the hydrogeology and the geochemistry of the Jurassic carbonates. This multidisciplinary effort provided a unique set of 3D data. The first purpose of this study is to integrate the geological, hydrogeological and geochemical data into a water flow conceptual model. Geological data include the study of cored wells, complete modern wire-line log sets in both cored and un-cored wells, and outcrop analogues. Hydrogeological data include transmissivity and hydraulic head measurements in the Oxfordian and Dogger limestone formations. Geochemical data include several on site measurements (pH, alkalinity, electrical conductivity, temperature) and chemical and isotopic analyses performed on water samples taken at selected depths. More than one hundred hydraulic tests have been performed since 1994 to measure transmissivity distribution in the Oxfordian and Dogger limestone. Several hydraulic testing methods were used in each well: global pumping tests, fluid logging tests, thermal flow logging tests and packer tests. After completion of the hydraulic tests, hydraulic heads were deduced from long term pressure measurements in open wells or in multi-packer completions; pressure monitoring lasted between a few months and more than 10 years. Long term/high volume pumping tests were also performed after the hydraulic tests to obtain a stationary composition of the well

    The production of high purity stable or radioactive isotopes ({>=} 99.99 per cent) using electromagnetic separation require for equipment having a high resolving power. Besides, and in order to collect rare or short half-life isotopes, the efficiency of the ion-source must be high ({eta} > 5 to 10 per cent). With this in view, the source built operates at high temperatures (2500-3000 C) and makes use of ionisation by electronic bombardment or of thermo-ionisation. A summary is given in the first part of this work on the essential characteristics of the isotope separator ion Sources; a diagram of the principle of the source built is then given together with its characteristics. In the second part are given the values of the resolving power and of the efficiency of the Grenoble isotope separator fitted with such a source. The resolving power measured at 10 per cent of the peak height is of the order of 200. At the first magnetic stage the efficiency is between 1 and 26 per cent for a range of elements evaporating between 200 and 3000 C. Thus equipped, the separator has for example given, at the first stage, 10 mg of {sup 180}Hf at (99.69 {+-} 0.1) per cent corresponding to an enrichment coefficient of 580; recently 2 mg of {sup 150}Nd at (99.996 {+-} 0.002) per cent corresponding to an enrichment coefficient of 4.2 x 10{sup 5} has been obtained at the second stage.

    Qualitative research methods are a robust tool for chaplaincy research questions. Similar to much of chaplaincy clinical care, qualitative research generally works with written texts, often transcriptions of individual interviews or focus group conversations and seeks to understand the meaning of experience in a study sample. This article describes three common methodologies: ethnography, grounded theory, and phenomenology. Issues to consider relating to the study sample, design, and analysis are discussed. Enhancing the validity of the data, as well reliability and ethical issues in qualitative research are described. Qualitative research is an accessible way for chaplains to contribute new knowledge about the sacred dimension of people's lived experience.

    Qualitative nurse researchers are required to make deliberate and sometimes complex methodological decisions about their work. Methodology in qualitative research is a comprehensive approach in which theory (ideas) and method (doing) are brought into close alignment. It can be difficult, at times, to understand the concept of methodology. The purpose of this research column is to: (1) define qualitative methodology; (2) illuminate the relationship between epistemology, ontology and methodology; (3) explicate the connection between theory and method in qualitative research design; and 4) highlight relevant examples of methodological decisions made within cardiovascular nursing research. Although there is no "one set way" to do qualitative research, all qualitative researchers should account for the choices they make throughout the research process and articulate their methodological decision-making along the way.

    This paper provides a primer for qualitative research in medical education. Our aim is to equip readers with a basic understanding of qualitative research and prepare them to judge the goodness of fit between qualitative research and their own research questions. We provide an overview of the reasons for choosing a qualitative research approach and potential benefits of using these methods for systematic investigation. We discuss developing qualitative research questions, grounding research in a philosophical framework, and applying rigorous methods of data collection, sampling, and analysis. We also address methods to establish the trustworthiness of a qualitative study and introduce the reader to ethical concerns that warrant special attention when planning qualitative research. We conclude with a worksheet that readers may use for designing a qualitative study. Medical educators ask many questions that carefully designed qualitative research would address effectively. Careful attention to the design of qualitative studies will help to ensure credible answers that will illuminate many of the issues, challenges, and quandaries that arise while doing the work of medical education.

    Industrial emissions, deteriorating or improperly removed lead paint, and the use of lead additives in fuel have left a substantial burden of heavy metals, such as lead, in urban soils. Much of this lead remains near the surface where it has the potential to impact human health. Exposure to lead, especially in children, can have lasting impacts on neurological development and academic achievement. Urban gardening, in particular, is an activity that could result in increased exposure to soil lead for many unsuspecting gardeners. During the summer of 2012, more than 1,061 surface soil samples were collected from an approximately 1.25 acre urban community garden in Terre Haute, Indiana. Samples were collected to evaluate the spatial distribution of lead across the community garden on the plot level. The results highlight the variability that can be seen within small areas of a former residential property, for example lead concentrations that are low (garden plot as concentrations that are considered high (>600 ppm). Based on the results of this work, several areas of concern were identified and the community garden was reconfigured to reduce potential lead exposure to gardeners and the local community.

This paper highlights some of the difficulties during searches of electronic databases for qualitative research. These difficulties relate to the descriptive nature of the titles used in some qualitative studies, the variable information provided in abstracts, and the differences in the ind...

    The third and final discussion paper of the German Network of Health Services Research's (DNVF) "Qualitative Methods Working Group" demonstrates methods for the evaluation and quality of qualitative research in health services research. In this paper we discuss approaches described in evaluating qualitative studies, including: an orientation to the general principles of empirical research, an approach-specific course of action, as well as procedures based on the research-process and criteria-oriented approaches. Divided into general and specific aspects to be considered in a qualitative study quality evaluation, the central focus of the discussion paper undertakes an extensive examination of the process and criteria-oriented approaches. The general aspects include the participation of relevant groups in the research process as well as ethical aspects of the research and data protection issues. The more specific aspects in evaluating the quality of qualitative research include considerations about the research interest, research questions, and the selection of data collection methods and types of analyses. The formulated questions are intended to guide reviewers and researchers to evaluate and to develop qualitative research projects appropriately. The intention of this discussion paper is to ensure a transparent research culture, and to reflect on and discuss the methodological and research approach of qualitative studies in health services research. With this paper we aim to initiate a discussion on high quality evaluation of qualitative health services research. © Georg Thieme Verlag KG Stuttgart · New York.

    Document available in extended abstract form only. The Meuse/Haute-Marne site covers an area of approximately 250 km 2 and it is located in the eastern part of the Paris Basin (200 000 km 2 ). The Callovo-Oxfordian clay formation, which is found throughout the Paris Basin, is considered as a potential host rock for France's high- and intermediate-level long-lived radioactive waste. At the project site (the Sector area), the Callovo-Oxfordian Formation is encountered at a depth of roughly 500 m, with a minimum thickness of approximately 130 m and a very low (on the order of 10-14 m/s) hydraulic conductivity. The Callovo-Oxfordian layer is confined between an overlying limestone aquifer of Jurassic-Oxfordian age and an underlying limestone of Jurassic-Dogger age. Analyses of the possible transfer of solute from the host formation into the surrounding aquifer system during the next million of years are required for safety calculations. These analyses are based on estimates of the future geomorphologic and climatic evolution of the area and on calculations of the future evolution of groundwater flow and solute transport behaviour in the units surrounding the Callovo-Oxfordian clay. To support the analyses of the future regional and local hydrogeological evolutions, a single-continuum multi-scale hydrogeological model of the Paris Basin and the Meuse/Haute-Marne sector has been developed. The model represents 27 hydrogeological units at the scale of the Paris Basin, and it is refined at the scale of the studied domain (the Sector area) to represent 27 different layers that range in age from Trias to Jurassic-Portlandian. The model has been calibrated to observed hydraulic heads. The present work deals with permafrost generation and retreat during a glacial cycle and the resulting consequences on the groundwater flow patterns within the Meuse/Haute-Marne aquifer system. The conceptual model of permafrost generation is that the pore water is frozen to create ice

  10. La territorialisation des politiques environnementales

    Directory of Open Access Journals (Sweden)

    Amédée Mollard

    2010-10-01

    Full Text Available Le point de départ de cet article est la grande variabilité de la pollution nitrique diffuse de l’eau due à l’agriculture. Celle-ci dépend en particulier du climat, des types de sol et des systèmes de production agricole. Nos recherches réalisées de façon interdisciplinaire à partir de deux sites différents en France, montrent que cette hétérogénéité spatio-temporelle conditionne les pratiques agricoles mises en œuvre pour réduire la pollution au niveau de la norme admise. De ce fait, les pratiques les plus « coût-efficaces » diffèrent d’un territoire à l’autre, en fonction des caractéristiques locales. Ces résultats mettent donc en évidence une efficacité potentielle d’une territorialisation des politiques publiques. En théorie, de telles politiques sont considérées comme optimales par les économistes, car elles incitent les agents à moduler leurs efforts en fonction de la sensibilité du milieu. Mais, selon les études empiriques, cet avantage serait annulé par un coût élevé de mise en œuvre, de contrôle et de surveillance. Pour maintenir leur avantage sur des politiques uniformes, les politiques territorialisées devraient être mises en œuvre à un niveau spatial optimal. Un tel niveau devrait au minimum atteindre un compromis entre l’économie réalisée grâce à une modulation adaptée aux conditions locales et les sur-coûts dus à la décentralisation des solutions mises en œuvre. Cet article analyse la pertinence d’une prise en compte de ces spécificités par des politiques territorialisées. L’efficacité d’une régulation différenciée de la pollution nitrique est étudiée ici en évaluant l’importance de la variabilité spatiale des paramètres physiques et des coûts de la territorialisation.The paper starts with the wide variability of nonpoint water nitrogenous pollution generated by agriculture. This variability depends especially on climate, soil types and farming systems. Our interdisciplinary researches, carried out on two different sites in France, show that space and time heterogeneity influence farm practices to be implemented in order to reduce pollution at the standard level. Hence the most cost-effective farm practices are different from one place to another, depending on local characteristics. Therefore this result emphasises the potential efficiency of spatially targeted policies. Theoretically, such policies are considered optimal, since economic agents tune their efforts according to the sensitivity of the milieu where they operate. But, according to empirical analyses, this advantage is counteracted by a high cost of implementation, monitoring and enforcement. In order to maintain the advantage of site-specific policies versusuniform policies, the former have to be implemented at an optimal level of space. This level should at least allow for a trade-off between lower expenses due to an appropriate tuning to the local conditions and heavier costs of decentralised measures. This paper deals with this specific question regarding territorialized policies. It is based on a study of the efficiency of differentiating the way this pollution is regulated, focussed on assessing the importance of spatial variability in physical parameters and in site-specific policies’ costs.

    2008-01-01

    The theory of chaos offers useful tools for systems analysis. However, models of complex systems are based on a network of inconsistent, space and uncertain knowledge items. Traditional quantitative methods of chaos analysis are therefore not applicable. The paper by the same authors [Vicha T, Dohnal M. Qualitative identification of chaotic systems behaviours. Chaos, Solitons and Fractals, in press, [Log. No. 601019] ] presents qualitative interpretation of some chaos concepts. There are only three qualitative values positive/increasing, negative/decreasing and zero/constant. It means that any set of qualitative multidimensional descriptions of unsteady state behaviours is discrete and finite. A finite upper limit exists for the total number of qualitatively distinguishable scenarios. A set of 21 published chaotic models is solved qualitatively and 21 sets of all existing qualitative scenarios are presented. The intersection of all 21 scenario sets is empty. There is no such a behaviour which is common for all 21 models. The set of 21 qualitative models (e.g. Lorenz, Roessler) can be used to compare chaotic behaviours of an unknown qualitative model with them to evaluate if its chaotic behaviours is close to e.g. Lorenz chaotic model and how much

  16. Qualitative research in travel behavior studies

    Energy Technology Data Exchange (ETDEWEB)

    Mars Aicart, M.L.; Ruiz Sanchez, T.; Arroyo Lopez, M.R.

    2016-07-01

    Qualitative methodology is extensively used in a wide range of scientific areas, such as Sociology and Psychology, and it is been used to study individual and household decision making processes. However, in the Transportation Planning and Engineering domain it is still infrequent to find in the travel behavior literature studies using qualitative techniques to explore activity-travel decisions. The aim of this paper is first, to provide an overview of the types of qualitative techniques available and to explore how to correctly implement them. Secondly, to highlight the special characteristics of qualitative methods that make them appropriate to study activity-travel decision processes. Far from been an unempirical or intuitive methodology, using qualitative methods properly implies a strong foundation on theoretical frameworks, a careful design of data collection and a deep data analysis. For such a purpose, a review of the scarce activity-travel behavior literature using qualitative methods, or a combination of qualitative and quantitative approaches, is presented. The use of qualitative techniques can play a role of being a supplementary way of obtaining information related to activity-travel decisions which otherwise it would be extremely difficult to find. This work ends with some conclusions about how qualitative research could help in making progress on activity-travel behavior studies. (Author)

    2009-12-01

    Within the context of selection of a site for a future deep storage for high- and intermediate-level activity and long life wastes, this report comments the various results of geological investigations and characterizations performed on this site during the past years. It notices that the most recent results (2007 and 2008) do not put previous conclusions (2005) into question. It recalls the required geological characteristics for such a storage site and compares them with the site characteristics. The IRSN agrees with the technical criteria adopted by the ANDRA for the choice of a zone of interest for a deepened investigation, and more particularly for this particular zone located on the territory of both French departments of Meuse and Haute-Marne

    To conceptualise and discuss dissemination bias in qualitative research. It is likely that the mechanisms leading to dissemination bias in quantitative research, including time lag, language, gray literature, and truncation bias also contribute to dissemination bias in qualitative research. These conceptual considerations have informed the development of a research agenda. Further exploration of dissemination bias in qualitative research is needed, including the extent of non-dissemination and related dissemination bias, and how to assess dissemination bias within qualitative evidence syntheses. We also need to consider the mechanisms through which dissemination bias in qualitative research could occur to explore approaches for reducing it. Copyright © 2017 Elsevier Inc.

  2. Qualitative identification of chaotic systems behaviours

    International Nuclear Information System (INIS)

    Vicha, T.; Dohnal, M.

    2008-01-01

    There are only three qualitative values positive, negative and zero. This means that there is a maximal number of qualitatively distinguishable scenarios, prescribed by the number of variables and the highest qualitative derivative taken into consideration. There are several chaos related tasks, which can be solved with great difficulties on the numerical level if multidimensional problems are studied. One of them is the identification of all qualitatively different behaviours. To make sure that all distinctive qualitative scenarios are identified a qualitative interpretation of a classical quantitative phase portrait is used. The highest derivatives are usually the second derivatives as it is not possible to safely identify higher derivatives if tasks related to ecology or economics are studied. Two classical models are discussed - Damped oscillation (non chaotic) and Lorenz model (chaotic). There are 191 scenarios of the Lorenz model if only the second derivatives are considered. If the third derivatives are taken into consideration then the number of scenarios is 2619. Complete qualitative results are given in details

    Colorafi, Karen Jiggins; Evans, Bronwynne

    2016-07-01

    The purpose of this methodology paper is to describe an approach to qualitative design known as qualitative descriptive that is well suited to junior health sciences researchers because it can be used with a variety of theoretical approaches, sampling techniques, and data collection strategies. It is often difficult for junior qualitative researchers to pull together the tools and resources they need to embark on a high-quality qualitative research study and to manage the volumes of data they collect during qualitative studies. This paper seeks to pull together much needed resources and provide an overview of methods. A step-by-step guide to planning a qualitative descriptive study and analyzing the data is provided, utilizing exemplars from the authors' research. This paper presents steps to conducting a qualitative descriptive study under the following headings: describing the qualitative descriptive approach, designing a qualitative descriptive study, steps to data analysis, and ensuring rigor of findings. The qualitative descriptive approach results in a summary in everyday, factual language that facilitates understanding of a selected phenomenon across disciplines of health science researchers. © The Author(s) 2016.

    2011-01-01

    The Green Valley reclaimed coal refuse site, near Terre Haute, Ind., was mined for coal from 1948 to 1963. Subsurface coal was cleaned and sorted at land surface, and waste material was deposited over the native glacial till. Approximately 2.7 million cubic yards of waste was deposited over 159 acres (92.3 hectares) in tailings ponds and gob piles. During 1993, the Indiana Department of Natural Resources, Division of Reclamation, improved the site by grading gob piles, filling tailings ponds, and covering the refuse with a layer of glacial drift. During 2008, the Division of Reclamation and U.S. Geological Survey initiated a cooperative investigation to characterize the hydrogeology of the site and construct a calibrated groundwater flow model that could be used to simulate the results of future remedial actions. In support of the modeling, a data-collection network was installed at the Green Valley site to measure weather components, geophysical properties, groundwater levels, and stream and seep flow. Results of the investigation indicate that (1) there is negligible overland flow from the site, (2) the prevailing groundwater-flow direction is from northeast to southwest, with a much smaller drainage to the northeast, (3) there is not a direct hydraulic connection between the refuse and West Little Sugar Creek, (4) about 24 percent of the groundwater recharge emerges through seeps, and water from the seeps evaporates or eventually flows to West Little Sugar Creek and the Green Valley Mine Pond, and (5) about 72 percent of groundwater recharge moves vertically downward from the coal refuse into the till and follows long, slow flow paths to eventual dischage points.

    Cleland, Jennifer Anne

    2017-06-01

    Qualitative research is very important in educational research as it addresses the "how" and "why" research questions and enables deeper understanding of experiences, phenomena and context. Qualitative research allows you to ask questions that cannot be easily put into numbers to understand human experience. Getting at the everyday realities of some social phenomenon and studying important questions as they are really practiced helps extend knowledge and understanding. To do so, you need to understand the philosophical stance of qualitative research and work from this to develop the research question, study design, data collection methods and data analysis. In this article, I provide an overview of the assumptions underlying qualitative research and the role of the researcher in the qualitative process. I then go on to discuss the type of research objectives which are common in qualitative research, then introduce the main qualitative designs, data collection tools, and finally the basics of qualitative analysis. I introduce the criteria by which you can judge the quality of qualitative research. Many classic references are cited in this article, and I urge you to seek out some of these further reading to inform your qualitative research program.

    1990-01-01

    The objectives of this project were: (1) to investigate the implications of qualitative modeling techniques for problems arising in the monitoring, diagnosis, and design of Space Station subsystems and procedures; (2) to identify the issues involved in using qualitative models to enhance and automate engineering functions. These issues include representing operational criteria, fault models, alternate ontologies, and modeling continuous signals at a functional level of description; and (3) to develop a prototype collection of qualitative models for fluid and thermal systems commonly found in Space Station subsystems. Potential applications of qualitative modeling to space-systems engineering, including the notion of intelligent computer-aided engineering are summarized. Emphasis is given to determining which systems of the proposed Space Station provide the most leverage for study, given the current state of the art. Progress on using qualitative models, including development of the molecular collection ontology for reasoning about fluids, the interaction of qualitative and quantitative knowledge in analyzing thermodynamic cycles, and an experiment on building a natural language interface to qualitative reasoning is reported. Finally, some recommendations are made for future research.

    Qualitative secondary analysis (QSA) is the use of qualitative data that was collected by someone else or was collected to answer a different research question. Secondary analysis of qualitative data provides an opportunity to maximize data utility, particularly with difficult-to-reach patient populations. However, qualitative secondary analysis methods require careful consideration and explicit description to best understand, contextualize, and evaluate the research results. In this article, we describe methodologic considerations using a case exemplar to illustrate challenges specific to qualitative secondary analysis and strategies to overcome them.

    This thesis deals with the study of an electrostatic high voltage generator having a voltage stability of the order of 10{sup -6} per minute. This equipment should be very useful in electron microscopy. The electrostatic generator is studied as a control system element: transfer function, parasitic signals and noise are determined and a mathematical model is proposed. A theoretical study of the open loop transfer function, stability, transient response, voltage stabilization of five different control systems shows which one should be able to fulfill the requirements There follows a detailed study of drift, a description of the actual system and performance data. (author) [French] Cette etude concerne un generateur electrostatique capable de fournir une tres haute tension continue dont la stabilite relative est de l'ordre de 10{sup -6} pendant une minute. Une telle performance rend cet appareillage tres utile en microscopie electronique. La generatrice electrostatique est etudiee en tant qu'element d'un systeme asservi: on determine successivement la fonction de transfert, les perturbations, le bruit de fond et le modele mathematique. L'etude de cinq differents circuits de regulation en ce qui concerne leur fonction de transfert, stabilite, reponse en regime transitoire, attenuation des perturbations, permettra de choisir le systeme qui semble le mieux repondre aux exigences.

    Full Text Available Cette étude présente les investigations menées sur la fragilisation par le zinc liquide d'un acier électro-zingué. La caractérisation mécanique par essais de traction à haute température montre un important puits de ductilité entre environ 700 ∘C et environ 950 ∘C. L'observation au MEB des éprouvettes de traction indique que, dans la gamme de température observée pour laquelle il y a fragilisation, on a mouillage intergranulaire des joints de grains de l'acier à l'interface acier/revêtement par des films de Zn. La corrélation entre mouillage intergranulaire thermiquement activé d'une part, et propagation de fissure lors du chargement d'autre part, est discutée. This study deals with liquid zinc embrittlement for electro-galvanized steel. Mechanical characterization by high temperature tensile tests shows a drastic loss of ductility between 700 ∘C and 950 ∘C. SEM investigations show that steel grain boundaries under the steel/coating interface are penetrated by a liquid Zn channel, only in the temperature range of embrittlement. A correlation can be drawn between i thermal activated-grain boundary wetting and ii crack propagation in presence of external stress.

    2013-10-01

    Qualitative translational research refers to the "bench-to-bedside" enterprise of harnessing knowledge from the basic sciences to produce new treatment options or nursing interventions for patients. Three evidence-based translational problems related to qualitative translational research discussed this year address the interfaces among the nursing paradigm, the basic sciences, and clinical nursing work. This article illustrates the definition of translational science and translational blocks of evidence-based practice; discusses the qualitative research perspective in evidence synthesis, evidence translation and evidence utilization; and discusses the research questions that must be answered to solve the problems of the three translational gaps from the qualitative research perspective. Qualitative inquiry has an essential role to play in efforts to improve current healthcare-provider nursing interventions, experiences, and contexts. Thus, it is vital to introduce qualitative perspectives into evidence-based practice from the knowledge discovery through to the knowledge implementation process.

    Document available in extended abstract form only. The GEO database (geo-scientific database of the Meuse/Haute-Marne Center) is a tool developed by Andra, with a view to group in a secured computer form all data related to the acquisition of in situ and laboratory measurements made on solid and fluid samples. This database has three main functions: - Acquisition and management of data and computer files related to geological, geomechanical, hydrogeological and geochemical measurements on solid and fluid samples and in situ measurements (logging, on sample measurements, geological logs, etc). - Available consultation by the staff on Andra's intranet network for selective viewing of data linked to a borehole and/or a sample and for making computations and graphs on sets of laboratory measurements related to a sample. - Physical management of fluid and solid samples stored in a 'core library' in order to localize a sample, follow-up its movement out of the 'core library' to an organization, and carry out regular inventories. The GEO database is a relational Oracle data base. It is installed on a data server which stores information and manages the users' transactions. The users can consult, download and exploit data from any computer connected to the Andra network or Internet. Management of the access rights is made through a login/ password. Four geo-scientific explanations are linked to the Geo database, they are: - The Geosciences portal: The Geosciences portal is a web Intranet application accessible from the ANDRA network. It does not require a particular installation from the client and is accessible through the Internet navigator. A SQL Server Express database manages the users and access rights to the application. This application is used for the acquisition of hydrogeological and geochemical data collected on the field and on fluid samples, as well as data related to scientific work carried out at surface level or in drifts

It is important as well as interesting to study relation among them. This article attempts to present the concept of qualitative robustness as forwarded by first proponents and its later development. It illustrates intricacies of qualitative robustness and its relation with consistency, and also tries to remove commonly believed misunderstandings about relation between influence function and qualitative robustness citing some examples from literature and providing a new counter-example. At the end it places a useful finite and a simulated version of   qualitative robustness index (QRI. In order to assess the performance of the proposed measures, we have compared fifteen estimators of correlation coefficient using simulated as well as real data sets.

    Qualitative research methodologies are being used more frequently in audiology as it allows for a better understanding of the perspectives of people with hearing impairment. This article describes why and how international interdisciplinary qualitative research can be conducted. This paper is based on a literature review and our recent experience with the conduction of an international interdisciplinary qualitative study in audiology. We describe some available qualitative methods for sampling, data collection, and analysis and we discuss the rationale for choosing particular methods. The focus is on four approaches which have all previously been applied to audiologic research: grounded theory, interpretative phenomenological analysis, conversational analysis, and qualitative content analysis. This article provides a review of methodological issues useful for those designing qualitative research projects in audiology or needing assistance in the interpretation of qualitative literature.

    We tested a theory that mind mapping could be used as a tool in qualitative research to transcribe and analyse an interview. We compared results derived from mind mapping with those from interpretive phenomenological analysis by examining patients' and carers' perceptions of a new nurse-led service. Mind mapping could be used to rapidly analyse simple qualitative audio-recorded interviews. More research is needed to establish the extent to which mind mapping can assist qualitative researchers.

    International Nuclear Information System (INIS)

    Tabani, P.; Hermand, G.; Delay, J.; Mangeot, A.

    2010-01-01

    Document available in extended abstract form only. ANDRA is directly responsible for all scientific data acquired in real time and wire-line at the Meuse Haute- Marne underground research laboratory. To fulfil the needs for the acquisition, storage and display of realtime data, Andra decided to develop and install a system called SAGD (Systeme d'Acquisition et de Gestion des Donnees). With this view, a system was designed to: - Determine the acquisition tools and methods so that technical failures would not result in the loss of data or the acquisition of erroneous data, - Store (conservation) in the long-term all data in a single place in a single form, - Allow the diffusion and free access of data to the large community of ANDRA researchers, partners and service contractors in a single fluid way whatever the source of the data. - Help external communication through a user friendly and easy to understand presentation of the recorded data. S.A.G.D fulfils these objectives by: - Making available in real time, and through a single system, all experimental data under acquisition at the MHM Center and Mont Terri laboratory, - Displaying the recorded data on temporal windows and specific time step, - Allowing remote control of the experimentations, - Ensuring the traceability of all recorded information, - Ensuring data storage in a data base. S.A.G.D has been deployed in the first experimental drift at -445 m in November 2004. It was subsequently extended to the underground Mont Terri laboratory in Switzerland in 2005 and to the entire surface logging network of the Meuse / Haute-Marne Center in 2008. The SAGD computer network is an autonomous network consisting of optical fiber links which transmits experimentation data to the servers and computers in the control room, whether they originate from the bottom of a borehole or surface level. A high speed link between Mont Terri and Bure allows remote control of all the experimentations and the centralization of all

    L'expérience LHCb, menée dans le cadre du CERN, dispose d'un réseau standard pour acquérir les données produites par les collisions du LHC. Les différents serveurs qui font partie de ce réseau, supportent de nombreux services. En l'état, une panne physique peut rendre un service complètement indisponible, et peut-être interrompre l'acquisition de données. C'est pour cela qu'il faut que le système d'acquisition de données et le système de commande soient les plus fiables possibles. Pour résoudre ce problème, il existe une solution: la haute disponibilité, basée sur une redondance de matériel et la mise en place de cluster. Cette solution peut être amélioré par l'utilisation conjointe de mécanismes de virtualisations. Ma tâche a été d'étudier et de comparer différents types d'outil de virtualisation et de les implémenter sur un cluster.

    Qualitative studies are gaining their credibility after a period of being misinterpreted as "not being quantitative." Qualitative method is a broad umbrella term for research methodologies that describe and explain individuals' experiences, behaviors, interactions, and social contexts. In-depth interview, focus groups, and participant observation are among the qualitative methods of inquiry commonly used in psychiatry. Researchers measure the frequency of occurring events using quantitative methods; however, qualitative methods provide a broader understanding and a more thorough reasoning behind the event. Hence, it is considered to be of special importance in psychiatry. Besides hypothesis generation in earlier phases of the research, qualitative methods can be employed in questionnaire design, diagnostic criteria establishment, feasibility studies, as well as studies of attitude and beliefs. Animal models are another area that qualitative methods can be employed, especially when naturalistic observation of animal behavior is important. However, since qualitative results can be researcher's own view, they need to be statistically confirmed, quantitative methods. The tendency to combine both qualitative and quantitative methods as complementary methods has emerged over recent years. By applying both methods of research, scientists can take advantage of interpretative characteristics of qualitative methods as well as experimental dimensions of quantitative methods.

    2012-04-01

    Full Text Available Although qualitative research methods remain marginalized in certain disciplines, qualitative inquiry has within the last couple of decades become generally accepted as a legitimate scientific way of working. Today, society at large is making more use of qualitative research than ever, not just in laudable social justice research, for example, but also in relation to market and consumer research and focus groups for different political parties. With this in mind, I wish to discuss three current questions for qualitative researchers: The first I will refer to as “ethical progressivism versus new ethical challenges”. Is qualitative research as such more ethical and progressive than quantitative research (as some have argued, or do qualitative researchers on the contrary face more elusive and perhaps difficult ethical challenges? The second question is called “solid evidence versus subjective anecdotes”. How should qualitative researchers respond to the current call for evidence? Should they seek legitimacy by accepting the dominant politics of evidence, or should they play by their own rules with the risk of increasing marginalization? The third question is “method versus intuition”. Should qualitative researchers strive for maximum transparency by following accepted methods, or should they proceed more intuitively like artists to create their stories? Both sides of the questions have their influential advocates today. I will argue that all three questions are handled most fruitfully by conceiving of qualitative research as a craft.

    This is the second part of a 3-part discussion paper by the working group on "Qualitative Methods" in the German network of health services research (DNVF) that shall contribute to the development of a memorandum concerning qualitative health services research. It aims to depict the different types of qualitative research that are conducted in health services research in Germany. In addition, the authors present a specific set of qualitative data collection and analysis tools to demonstrate the potential of qualitative research for health services research. QUALITATIVE RESEARCH IN HEALTH SERVICES RESEARCH - AN OVERVIEW: To give an overview of the types of qualitative research conducted in German health services research, the abstracts of the 8th German Conference on Health Services Research were filtered to identify qualitative or mixed-methods studies. These were then analysed by looking at the context which was studied, who was studied, the aims of the studies, and what type of methods were used. Those methods that were mentioned most often for data collection and analysis are described in detail. QUALITATIVE RESEARCH AT THE CONFERENCE FOR HEALTH SERVICES RESEARCH 2009: Approximately a fifth of all abstracts (n=74) had a qualitative (n=47) or a mixed-methods approach combining quantitative and qualitative methods (n=27). Research aims included needs assessment (41%), survey development (36%), evaluation (22%), and theorizing (1%). Data collection mostly consisted of one-on-one interviews (n=45) and group discussions (n=29). Qualitative content analysis was named in 35 abstracts, 30 abstracts did not reference their method of analysis. In addition to a quantitative summary of the abstract findings, the diversity of fields addressed by qualitative methods is highlighted. Although drawing conclusions on the use of qualitative methods in German health services research from the analysis of conference abstracts is not possible, the overview we present demonstrates the

    The Patient-Centered Outcomes Research Institute (PCORI), created to fund research guided by patients, caregivers, and the broader health care community, offers a new research venue. Many (41 of 50) first funded projects involved qualitative research methods. This study was completed to examine the current state of the science of qualitative methodologies used in PCORI-funded research. Principal investigators participated in phenomenological interviews to learn (a) how do researchers using qualitative methods experience seeking funding for, implementing and disseminating their work; and (b) how may qualitative methods advance the quality and relevance of evidence for patients? Results showed the experience of doing qualitative research in the current research climate as "Being a bona fide qualitative researcher: Staying true to research aims while negotiating challenges," with overlapping patterns: (a) researching the elemental, (b) expecting surprise, and (c) pushing boundaries. The nature of qualitative work today was explicitly described and is rendered in this article.

  12. The Futures of Qualitative Social Research

    Directory of Open Access Journals (Sweden)

    Reiner Keller

    2014-01-01

    Full Text Available In this contribution I begin by reviewing past views on the future of qualitative social research. In different ways, all of these views give the same account of a problematic present state which must be overcome by following their own particular "mandatory directives" for future developments. I then discuss four structural mechanisms from which current problems in the transmission of qualitative and interpretative designs or approaches originate. Recently, supporters of "post-qualitative research" have addressed such problems by arguing for a form of strong theorism in qualitative social research. However, this type of response can lead back to an outdated dominance of theory over research and empirical substance. In conclusion, some alternative options for navigating qualitative and interpretative research through post-positivist waters are discussed. URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs1401165

Such research, however, has utilized, often uncritically, a 'cookbook' of methods for data collection, and common-sense principles for data analysis. This paper argues that qualitative HSR benefits from recognizing and drawing upon theoretical principles underlying qualitative data collection and analysis. A distinction is drawn between problem-orientated and theory-orientated research, in order to illustrate how problem-orientated research would benefit from the introduction of theoretical perspectives in order to develop the knowledge base of health services research.

  14. Qualitative tools and experimental philosophy

    Abstract Experimental philosophy brings empirical methods to philosophy. These methods are used to probe how people think about philosophically interesting things such as knowledge, morality, and freedom. This paper explores the contribution that qualitative methods have to make in this enterprise. I argue that qualitative methods have the potential to make a much greater contribution than they have so far. Along the way, I acknowledge a few types of resistance that proponents of qualitative methods in experimental philosophy might encounter, and provide reasons to think they are ill-founded.

    The vast majority of radiography research is subject to critique and evaluation from peers in order to justify the method and the outcome of the study. Within the quantitative domain, which the majority of medical imaging publications tend to fall into, there are prescribed methods for establishing scientific rigour and quality in order to critique a study. However, researchers within the qualitative paradigm, which is a developing area of radiography research, are often unclear about the most appropriate methods to measure the rigour (standards and quality) of a research study. This article considers the issues related to rigour, reliability and validity within qualitative research. The concepts of reliability and validity are briefly discussed within traditional positivism and then the attempts to use these terms as a measure of quality within qualitative research are explored. Alternative methods for research rigour in interpretive research (meanings and emotions) are suggested in order to compliment the existing radiography framework that exists for qualitative studies. The authors propose the use of an established model that is adapted to reflect the iterative process of qualitative research. Although a mechanistic approach to establishing rigour is rejected by many qualitative researchers, it is argued that a guide for novice researchers within a developing research base such as radiography is appropriate in order to establish the credibility and trustworthiness of a qualitative study.

Un mode de recouvrement adapté des rubans d'acier confère au composite une bonne étanchéité et des caractéristiques mécaniques élevées. Les propriétés physiques et chimiques de la matrice de résine permettent également d'obtenir une faible densité et une résistance convenable à la corrosion par les fluides pétroliers, l'eau de mer ou les boues de forage. Cette étude préliminaire comporte une analyse théorique simplifiée de ce type de structure composite, puis une partie expérimentale destinée a sélectionner les caractéristiques optimales de l'acier et de la résine et à vérifier les propriétés mécaniques et physico-chimiques obtenues sur ces tubes. Enfin, des exemples d'application en mer profonde destinés à comparer ces tubes composites aux tubes en acier sont présentés.

    Sample sizes must be ascertained in qualitative studies like in quantitative studies but not by the same means. The prevailing concept for sample size in qualitative studies is “saturation.” Saturation is closely tied to a specific methodology, and the term is inconsistently applied. We propose...... the concept “information power” to guide adequate sample size for qualitative studies. Information power indicates that the more information the sample holds, relevant for the actual study, the lower amount of participants is needed. We suggest that the size of a sample with sufficient information power...... and during data collection of a qualitative study is discussed....

    After the TMI nuclear power plant accident, the two topics of plant safety and operational efficiency became more important areas of artificial intelligence, which have difference characteristics. Qualitative deep model is the recently prospective technology of AI, that can overcome several handicaps of the existing expert systems such as lack of common sense reasoning. The application of AI to the large and complex system like nuclear power plants is typically and effectively done through a module-based hierarchical system. As each module has to be built with suitable AI system. Through the experiences of hierarchical system construction, we aimed to develop basic AI application schemes for the power plant safety and operational efficiency as well as basic technologies for autonomous power plants. The goal of the research is to develop qualitative reasoning technologies for nuclear power plants. For this purpose, the development of qualitative modeling technologies and qualitative behaviour prediction technologies of the power plant are accomplished. In addition, the feasibility of application of typical qualitative reasoning technologies to power plants is studied . The goal of the application is to develop intelligent control technologies of power plants, support technologies. For these purposes, we analyzed the operation of power plants according to its operation purpose: power generation operation, shut-down and start-up operation. As a result, qualitative model of basic components were sketched, including pipes, valves, pumps and heat exchangers. Finally, plant behaviour prediction technologies through qualitative plant heat transfer model and design support technologies through 2nd-order differential equation were developed. For the construction of AI system of power plants, we have studied on the mixed module based hierarchical software. As a testbed, we have considered the spent fuel system and the feedwater system. We also studied the integration

    Qualitative Physics(QP) has systematically been approached to qualitative modeling of physical systems for recent two decades. Designing intelligent systems for NPP requires an efficient representation of qualitative knowledge about the behavior and structure of NPP or its components. A novel representation of qualitative knowledge also enables intelligent systems to derive meaningful conclusions from incomplete or uncertain knowledge of a plant behavior. We look mainly into representative QP works on nuclear applications and the representation of qualitative knowledge for the diagnostic model, the qualitative simulation of a mental model of NPP operator, and the qualitative interpretation of the measured raw data from NPP. We present the challenging areas for QP applications in nuclear industry. QP technology will make NPP more intelligent

    Full Text Available For centuries, the local communities of yaks’ transhumant cattle farmers of the Tibetan High plateau have lived on their yak breeding activity, providing them with all they need: milk, a source of butter and cheese, and hair, which they weave into the heavy black tents that characterize the nomadic population. In the last decade, however, changes occurred that have destabilized this activity. The changes are three-fold: (1 increasing economic difficulty to live from this activity (Melvyn et al., 1990, and its two corollaries: (2 rural desertification (Yang, 1992 and (3 increasing herds’ sizes, threatening the environment (Wu, 1999. Norlha, meaning “wealth of the Gods”, proposes an alternative to remedy these problems. By improving the value added cattle that farmers derive from the yaks, Norlha’s social business model suggests that selling extremely high range products to luxury houses can be a way out of poverty and rural desertification for these communities.Pendant des siècles, les communautés locales d’éleveurs transhumants de yaks du haut plateau du Tibet ont vécu de leurs élevages qui leur fournissaient tout ce dont ils avaient besoin pour vivre : du lait, pour faire du beurre et du fromage, et de la laine, qu'ils tissaient pour fabriquer les épaisses tentes noires utilisées par les populations nomades. Toutefois, au cours des dix dernières années, l’élevage de yaks a été déstabilisé par certains  changements : (1 la difficulté de plus en plus grande à vivre de l’élevage (Melvyn et al., 1990, et ses deux corollaires, (2 la désertification rurale (Yang, 1992 et (3 des troupeaux de plus en plus importants qui menacent l’environnement (Wu, 1999.

    Qualitative research is an umbrella term for an array of attitudes and strategies for conducting inquiries that are aimed at discerning how human beings understand, experience, and interpret the social world. It is employed in many different academic disciplines most particularly in the social sciences and humanities, however recently more and more qualitative research is being conducted under the medical sciences including dentistry and orthodontics. This is due to its nature of in-depth investigation, which can provide answers to questions that cannot be satisfactorily answered using quantitative methods alone. The aims of this article are to discuss the characteristics of qualitative research, to review the orthodontic English literature, and to highlight the advantages of qualitative research in orthodontics. The literature review yielded several important conclusions regarding qualitative research in orthodontics: 1. most of the qualitative research done in orthodontics chose to use semi structured in-depth interviews for data collection; 2. qualitative research highlights aspects that are very important, and sometimes crucial to everyday practice and long term treatment; 3. there is a lack of qualitative studies in the field of orthodontics. Taking into account the nature of the orthodontic treatment, which is a prolonged one, demanding of a good orthodontist-patient rapport, and a wide perspective on behalf of the clinician, filling the gap in the discipline through conducting more qualitative studies aimed at understanding the point of view of the patient, as well as that of the clinician, may be beneficial for the improvement of the treatment.

    Qualitative inquiry requires that collected data is organised in a meaningful way, and this is referred to as data analysis. Through analytic processes, researchers turn what can be voluminous data into understandable and insightful analysis. This paper sets out the different approaches that qualitative researchers can use to make sense of their data including thematic analysis, narrative analysis, discourse analysis and semiotic analysis and discusses the ways that qualitative researchers can analyse their data. I first discuss salient issues in performing qualitative data analysis, and then proceed to provide some suggestions on different methods of data analysis in qualitative research. Finally, I provide some discussion on the use of computer-assisted data analysis.

  17. Employing a Qualitative Description Approach in Health Care Research.

    Science.gov (United States)

    Bradshaw, Carmel; Atkinson, Sandra; Doody, Owen

    2017-01-01

    A qualitative description design is particularly relevant where information is required directly from those experiencing the phenomenon under investigation and where time and resources are limited. Nurses and midwives often have clinical questions suitable to a qualitative approach but little time to develop an exhaustive comprehension of qualitative methodological approaches. Qualitative description research is sometimes considered a less sophisticated approach for epistemological reasons. Another challenge when considering qualitative description design is differentiating qualitative description from other qualitative approaches. This article provides a systematic and robust journey through the philosophical, ontological, and epistemological perspectives, which evidences the purpose of qualitative description research. Methods and rigor issues underpinning qualitative description research are also appraised to provide the researcher with a systematic approach to conduct research utilizing this approach. The key attributes and value of qualitative description research in the health care professions will be highlighted with the aim of extending its usage.

    2008-09-01

    This review of the literature synthesizes methodological recommendations for the use of translators and interpreters in cross-language qualitative research. Cross-language qualitative research involves the use of interpreters and translators to mediate a language barrier between researchers and participants. Qualitative nurse researchers successfully address language barriers between themselves and their participants when they systematically plan for how they will use interpreters and translators throughout the research process. Experienced qualitative researchers recognize that translators can generate qualitative data through translation processes and by participating in data analysis. Failure to address language barriers and the methodological challenges they present threatens the credibility, transferability, dependability and confirmability of cross-language qualitative nursing research. Through a synthesis of the cross-language qualitative methods literature, this article reviews the basics of language competence, translator and interpreter qualifications, and roles for each kind of qualitative research approach. Methodological and ethical considerations are also provided. By systematically addressing the methodological challenges cross-language research presents, nurse researchers can produce better evidence for nursing practice and policy making when working across different language groups. Findings from qualitative studies will also accurately represent the experiences of the participants without concern that the meaning was lost in translation.

  2. Scientific investigation in deep wells for nuclear waste disposal studies at the Meuse/Haute Marne underground research laboratory, Northeastern France

    Delay, Jacques; Rebours, Hervé; Vinsot, Agnès; Robin, Pierre

    Andra, the French National Radioactive Waste Management Agency, is constructing an underground test facility to study the feasibility of a radioactive waste disposal in the Jurassic-age Callovo-Oxfordian argillites. This paper describes the processes, the methods and results of a scientific characterization program carried out from the surface via deep boreholes with the aim to build a research facility for radioactive waste disposal. In particular this paper shows the evolution of the drilling programs and the borehole set up due to the refinement of the scientific objectives from 1994 to 2004. The pre-investigation phase on the Meuse/Haute-Marne site started in 1994. It consisted in drilling seven scientific boreholes. This phase, completed in 1996, led to the first regional geological cross-section showing the main geometrical characteristics of the host rock. Investigations on the laboratory site prior to the sinking of two shafts started in November 1999. The sinking of the shafts started in September 2000 with the auxiliary shaft completed in October 2004. The experimental gallery, at a depth of 445 m in the main shaft, was in operation by end 2004. During the construction of the laboratory, two major scientific programs were initiated to improve the existing knowledge of the regional hydrogeological characteristics and to accelerate the process of data acquisition on the shales. The aim of the 2003 hydrogeological drilling program was to determine, at regional scale, the properties of groundwater transport and to sample the water in the Oxfordian and Dogger limestones. The 2003-2004 programs consisted in drilling nine deep boreholes, four of which were slanted, to achieve an accurate definition of the structural features.

    The qualitative evaluation of system logic models is described as it pertains to assessing the reliability and safety characteristics of nuclear systems. Qualitative analysis of system logic models, i.e., models couched in an event (Boolean) algebra, is defined, and the advantages inherent in qualitative analysis are explained. Certain qualitative procedures that were developed as a part of fault-tree analysis are presented for illustration. Five fault-tree analysis computer-programs that contain a qualitative procedure for determining minimal cut sets are surveyed. For each program the minimal cut-set algorithm and limitations on its use are described. The recently developed common-cause analysis for studying the effect of common-causes of failure on system behavior is explained. This qualitative procedure does not require altering the fault tree, but does use minimal cut sets from the fault tree as part of its input. The method is applied using two different computer programs. 25 refs

    Since their discovery in the years 1986/87, the high critical temperature superconductors have reached nowadays performances interesting enough to conceive passive magnetic bearings and suspensions which would combined permanent magnets and naturally stable superconducting pellets. After underlining the principal factors that affect the superconductormagnet interaction, different experimental results are given about vertical and axial forces with some stiffness values. The magnetization curve of a superconductor help to understand the hysteretic behavior of the force as a function of the distance between superconductor and magnet. So called simple and hybrid structures of superconducting magnetic suspension are presented. Finally simple numerical simulations allow to draw some interesting conclusions about both geometry and best fitting structure of permanent magnets. Depuis leur découverte dans les années 1986/87, les supraconducteurs à haute température critique ont désormais atteint des performances intéressantes et rendent envisageables des paliers et suspensions magnétiques passives associant aimants permanents et pastilles supraconductrices naturellement stables. Après avoir indiqué les termes importants influençant l'interaction supraconducteur - aimant, différents relevés expérimentaux sont donnés pour les forces verticales et transversales avec quelques valeurs de raideurs. La courbe d'aimantation d'un supraconducteur permet de comprendre le comportement hystérétique de la force en fonction de la distance supraconducteur-aimant.

  5. Employing a Qualitative Description Approach in Health Care Research

    Science.gov (United States)

    Bradshaw, Carmel; Atkinson, Sandra; Doody, Owen

    2017-01-01

    A qualitative description design is particularly relevant where information is required directly from those experiencing the phenomenon under investigation and where time and resources are limited. Nurses and midwives often have clinical questions suitable to a qualitative approach but little time to develop an exhaustive comprehension of qualitative methodological approaches. Qualitative description research is sometimes considered a less sophisticated approach for epistemological reasons. Another challenge when considering qualitative description design is differentiating qualitative description from other qualitative approaches. This article provides a systematic and robust journey through the philosophical, ontological, and epistemological perspectives, which evidences the purpose of qualitative description research. Methods and rigor issues underpinning qualitative description research are also appraised to provide the researcher with a systematic approach to conduct research utilizing this approach. The key attributes and value of qualitative description research in the health care professions will be highlighted with the aim of extending its usage. PMID:29204457

 Qualitative research can make a valuable contribution to the study of quality and safety in health care. Sound ways of appraising qualitative research are needed, but currently there are many different proposals with few signs of an emerging consensus. One problem has been the tendency to treat qualitative research as a unified field. We distinguish universal features of quality from those specific to methodology and offer a set of minimally prescriptive prompts to assist with the assessme...

    Kidd, Sean A

    2002-03-01

    The acceptance of qualitative research in 15 journals published and distributed by the American Psychological Association (APA) was investigated. This investigation included a PsycINFO search using the keyword qualitative, an analysis of 15 APA journals for frequency of qualitative publication, a content analysis of the journal descriptions, and the results of qualitative interviews with 10 of the chief editors of those journals. The results indicate that there exists a substantial amount of interest in the potential contribution of qualitative methods in major psychological journals, although this interest is not ubiquitous, well defined, or communicated. These findings highlight the need for APA to state its position regarding the applicability of qualitative methods in the study of psychology.

    Science.gov (United States)

    Bedregal, Paula; Besoain, Carolina; Reinoso, Alejandro; Zubarew, Tamara

    2017-03-01

    Health care research requires different methodological approaches such as qualitative and quantitative analyzes to understand the phenomena under study. Qualitative research is usually the least considered. Central elements of the qualitative method are that the object of study is constituted by perceptions, emotions and beliefs, non-random sampling by purpose, circular process of knowledge construction, and methodological rigor throughout the research process, from quality design to the consistency of results. The objective of this work is to contribute to the methodological knowledge about qualitative research in health services, based on the implementation of the study, “The transition process from pediatric to adult services: perspectives from adolescents with chronic diseases, caregivers and health professionals”. The information gathered through the qualitative methodology facilitated the understanding of critical points, barriers and facilitators of the transition process of adolescents with chronic diseases, considering the perspective of users and the health team. This study allowed the design of a transition services model from pediatric to adult health services based on the needs of adolescents with chronic diseases, their caregivers and the health team.

    2015-09-01

    Qualitative methodologies are becoming increasingly widely used in health research. However, within some specialties, including renal medicine, qualitative approaches remain under-represented in the high-impact factor journals. Qualitative research can be undertaken: (i) as a stand-alone research method, addressing specific research questions; (ii) as part of a mixed methods approach alongside quantitative approaches or (iii) embedded in clinical trials, or during the development of complex interventions. The aim of this paper is to introduce qualitative research, including the rationale for choosing qualitative approaches, and guidance for ensuring quality when undertaking and reporting qualitative research. In addition, we introduce types of qualitative data (observation, interviews and focus groups) as well as some of the most commonly encountered methodological approaches (case studies, ethnography, phenomenology, grounded theory, thematic analysis, framework analysis and content analysis). © The Author 2015.

    Full Text Available The article considers the way that digital research technologies and online environments increasingly support new forms of qualitative research that have emerged as a result of new user groups taking up the practice of social research. New practitioners of qualitative research have entered the field from societies where qualitative research is a newly-established practice, and new cadres of "citizen researchers" have turned to qualitative methods for non-academic purposes. These groups challenge accepted understandings of qualitative methods. The article uses the example of qualitative software as a case study of how qualitative research is enabled by new digital tools that help new user groups extend the application of qualitative research methods.

    2012-03-01

    This article contributes to the debate about the use of reliability assessments in qualitative research in general, and health promotion research in particular. In this article, I examine the use of reliability assessments in qualitative health promotion research in response to health promotion researchers' commonly held misconception that reliability assessments improve the rigor of qualitative research. All qualitative articles published in the journal Health Promotion International from 2003 to 2009 employing reliability assessments were examined. In total, 31.3% (20/64) articles employed some form of reliability assessment. The use of reliability assessments increased over the study period, ranging from qualitative articles decreased. The articles were then classified into four types of reliability assessments, including the verification of thematic codes, the use of inter-rater reliability statistics, congruence in team coding and congruence in coding across sites. The merits of each type were discussed, with the subsequent discussion focusing on the deductive nature of reliable thematic coding, the limited depth of immediately verifiable data and the usefulness of such studies to health promotion and the advancement of the qualitative paradigm.

    Document available in extended abstract form only. In order to test the feasibility of disposing High-Level and Long-Lived Wastes (HLW-LL) in Callovo- Oxfordian clay formation (COx), the French National Radioactive Waste Management Agency (ANDRA) has carried out scientific and engineering investigations in the Meuse-Haute-Marne Underground Research Laboratory (URL) since November 1999. The COx (Figure 1) is of a special interest because of its very favourable characteristics for being a possible host rock for the disposal of radioactive waste. The project OHZ (Observation and Monitoring of the EDZ) was initiated in 2008 by ANDRA. In the framework of this project, a Mine-by experiment was performed in the niche GCS. The excavation was started on 29.01.2008. Displacement and pore pressure evolution during the excavation was measured by different sensors. Within the cooperation between BGR and ANDRA numerical calculations have been done using the code RockFlow to understand the hydraulic and mechanical (HM) coupling mechanisms of Callovo-Oxfordian clay-stone observed during the Mine-by experiment. Modelling results: With regard to the bedding of COx a transverse isotropy approach was applied. Thus the anisotropy effects caused by the bedding have been considered in coupled HM models (Massmann, 2009). Intensive parameter studies in comparison with measured deformation and pore pressure data have been conducted to reduce modelling uncertainties. Fully saturated models yield very precise results in the far field wherein excavation effect has its lower impact. Rapid decline of pore pressure and continuously increasing deformation subsequent to excavation in the near field could not be interpreted even taking shrinkage and partially saturation into consideration. During the Mine-by test, overpressures on sidewalls and reduced pressures on roof and floor were measured due to the mechanical effect on pore pressure which is induced by the bedding. Good agreement between

    2008-01-01

    On observing how qualitative and quantitative studies are reported in the biomedical literature it becomes evident that, besides the virtual absence of the former, they are presented in different ways. Authors of qualitative studies seem to need almost invariably to explain why they choose a qualitative approach whereas that does not occur in quantitative studies. This paper takes Ludwik Fleck's comparative epistemology as a means of exploring those differences empirically, illustrating on the basis of two studies dealing with different aspects of biomedical practices how qualitative methods can elucidate a variety of questions pertaining to this field. The paper concludes presenting some structural characteristics of the biomedical field which on one hand, would not be explored properly without employing qualitative methods and, on the other hand, can help understanding the little value given to qualitative techniques in this area.

    The authors described the general principles governing the design of a laboratory for experimenting and handling radioactive substances. The difficulties encountered are of two types: 1) those due to the dangers of external irradiation; 2) those due to the dangers of internal contamination. As an example, the authors describe the French achievements in this field and in particular: - the high-activity laboratories at Saclay; - the laboratory for the examination of irradiated fuels at Saclay; - the 'hot' laboratory of the CEN-Grenoble; - the alpha, beta and gamma laboratories of the CEN-Fontenay-aux-Roses. Finally, the report describes the protective materials used for these installations.

  11. QUAGOL: a guide for qualitative data analysis.

    Science.gov (United States)

    Dierckx de Casterlé, Bernadette; Gastmans, Chris; Bryon, Els; Denier, Yvonne

    2012-03-01

    Data analysis is a complex and contested part of the qualitative research process, which has received limited theoretical attention. Researchers are often in need of useful instructions or guidelines on how to analyze the mass of qualitative data, but face the lack of clear guidance for using particular analytic methods. The aim of this paper is to propose and discuss the Qualitative Analysis Guide of Leuven (QUAGOL), a guide that was developed in order to be able to truly capture the rich insights of qualitative interview data. The article describes six major problems researchers are often struggling with during the process of qualitative data analysis. Consequently, the QUAGOL is proposed as a guide to facilitate the process of analysis. Challenges emerged and lessons learned from own extensive experiences with qualitative data analysis within the Grounded Theory Approach, as well as from those of other researchers (as described in the literature), were discussed and recommendations were presented. Strengths and pitfalls of the proposed method were discussed in detail. The Qualitative Analysis Guide of Leuven (QUAGOL) offers a comprehensive method to guide the process of qualitative data analysis. The process consists of two parts, each consisting of five stages. The method is systematic but not rigid. It is characterized by iterative processes of digging deeper, constantly moving between the various stages of the process. As such, it aims to stimulate the researcher's intuition and creativity as optimal as possible. The QUAGOL guide is a theory and practice-based guide that supports and facilitates the process of analysis of qualitative interview data. Although the method can facilitate the process of analysis, it cannot guarantee automatic quality. The skills of the researcher and the quality of the research team remain the most crucial components of a successful process of analysis. Additionally, the importance of constantly moving between the various stages

    Ce travail se situe dans le cadre de l'expérience ATLAS auprès du Grand Collisionneur Hadronique (LHC) qui sera construit au CERN. Il consiste en l'étude de la réponse en courant de détecteurs au silicium de grande surface, irradiés par des neutrons ou des protons de façon à reproduire l'environnement de hautes radiations auquel le détecteur ATLAS devra faire face. A l'aide d'une modélisation du transport des charges produites par le passage de particules alpha ou bêta dans un détecteur au silicium et d'un ensemble de données expérimentales, il est possible d'obtenir certaines caractéristiques électriques importantes des détecteurs. Ces caractéristiques sont: la concentration effective de dopants (ce qui détermine la tension de désertion d'un semi-conducteur), le piégeage des porteurs de charge (donnant l'efficacité de la collection des charges), et les mobilités des électrons et des trous (influençant le temps nécessaire à la collection des charges).

    Qualitative data provide rich information on research questions in diverse fields. Recent calls for increased transparency and openness in research emphasize data sharing. However, qualitative data sharing has yet to become the norm internationally and is particularly uncommon in the United States. Guidance for archiving and secondary use of qualitative data is required for progress in this regard. In this study, we review the benefits and concerns associated with qualitative data sharing and then describe the results of a content analysis of guidelines from international repositories that archive qualitative data. A minority of repositories provide qualitative data sharing guidelines. Of the guidelines available, there is substantial variation in whether specific topics are addressed. Some topics, such as removing direct identifiers, are consistently addressed, while others, such as providing an anonymization log, are not. We discuss the implications of our study for education, best practices, and future research.

    To provide an overview of bracketing as a skill in unstructured qualitative research interviews. Researchers affect the qualitative research process. Bracketing in descriptive phenomenology entails researchers setting aside their pre-understanding and acting non-judgementally. In interpretative phenomenology, previous knowledge is used intentionally to create new understanding. A literature search of bracketing in phenomenology and qualitative research. This is a methodology paper examining the researchers' impact in creating data in creating data in qualitative research. Self-knowledge, sensitivity and reflexivity of the researcher enable bracketing. Skilled and experienced researchers are needed to use bracketing in unstructured qualitative research interviews. Bracketing adds scientific rigour and validity to any qualitative study.

    Heasman, Brett; Reader, Tom W

    2015-10-01

    The contribution of qualitative methods to evidence-based medicine is growing, with qualitative studies increasingly used to examine patient experience and unsafe organizational cultures. The present review considers qualitative research recently conducted on teamwork and organizational culture in the ICU and also other acute domains. Qualitative studies have highlighted the importance of interpersonal and social aspects of healthcare on managing and responding to patient care needs. Clear/consistent communication, compassion, and trust underpin successful patient-physician interactions, with improved patient experiences linked to patient safety and clinical effectiveness across a wide range of measures and outcomes. Across multidisciplinary teams, good communication facilitates shared understanding, decision-making and coordinated action, reducing patient risk in the process. Qualitative methods highlight the complex nature of risk management in hospital wards, which is highly contextualized to the demands and resources available, and influenced by multilayered social contexts. In addition to augmenting quantitative research, qualitative investigations enable the investigation of questions on social behaviour that are beyond the scope of quantitative assessment alone. To develop improved patient-centred care, health professionals should therefore consider integrating qualitative procedures into their existing assessments of patient/staff satisfaction.

  4. Perils and potentials in qualitative psychology.

    Science.gov (United States)

    Brinkmann, Svend

    2015-06-01

    Famously, Ebbinghaus declared that psychology has a long past, but only a short history. Psychology, as something implicit to human conduct, is as old as the human race, but the science, as an explicit investigative reflection upon that conduct, is a recent invention. Within the short history of psychology, we find an even shorter history of qualitative psychology specifically. Although most founding fathers (Freud, Piaget, Bartlett etc.) worked as "qualitative psychologists", they found no need to thematize their methods of inquiry in this manner. Since around 1980, however, a field has established itself that can be called qualitative psychology. In this paper, I discuss how this field can move sensibly into the future, and I highlight two perils and two potentials. The perils stem from neo-positivism and a threatening "McDonaldization" of qualitative research, while the potentials are related to proliferation of new forms of inquiry and a transcending of disciplinary boundaries.

    Full Text Available In this paper, I am going to outline ways of combining qualitative and quantitative steps of analysis on five levels. On the technical level, programs for the computer-aided analysis of qualitative data offer various combinations. Where the data are concerned, the employment of categories (for instance by using qualitative content analysis allows for combining qualitative and quantitative forms of data analysis. On the individual level, the creation of types and the inductive generalisation of cases allow for proceeding from individual case material to quantitative generalisations. As for research design, different models can be distinguished (preliminary study, generalisation, elaboration, triangulation which combine qualitative and quantitative steps of analysis. Where the logic of research is concerned, it can be shown that an extended process model which combined qualitative and quantitative research can be appropriate and thus lead to an integration of the two approaches.

    Full Text Available This paper describes a faculty development model called the highly relevant mentoring (HRM model; the model includes a framework as well as some practical strategies for meeting the professional development needs of faculty who teach web-based courses. The paper further emphasizes the need for faculty and administrative buy-in for HRM and examines relevant theories that may be used to guide HRM in web-based teaching environments. Of note is that HRM was conceived by the instructional design staff who contributed to this paper before the concept of high impact mentoring appeared in the recent literature (2009. While the model is appropriate in various disciplines and professions, the examples and scenarios provided are drawn from a Canadian university’s experience of using HRM, in conjunction with a pedagogical approach called ICARE, in a variety of nursing courses and programs.

    2014-01-01

    Qualitative and mixed methods play a prominent role in mental health services research. However, the standards for their use are not always evident, especially for those not trained in such methods. This paper reviews the rationale and common approaches to using qualitative and mixed methods in mental health services and implementation research based on a review of the papers included in this special series along with representative examples from the literature. Qualitative methods are used to provide a “thick description” or depth of understanding to complement breadth of understanding afforded by quantitative methods, elicit the perspective of those being studied, explore issues that have not been well studied, develop conceptual theories or test hypotheses, or evaluate the process of a phenomenon or intervention. Qualitative methods adhere to many of the same principles of scientific rigor as quantitative methods, but often differ with respect to study design, data collection and data analysis strategies. For instance, participants for qualitative studies are usually sampled purposefully rather than at random and the design usually reflects an iterative process alternating between data collection and analysis. The most common techniques for data collection are individual semi-structured interviews, focus groups, document reviews, and participant observation. Strategies for analysis are usually inductive, based on principles of grounded theory or phenomenology. Qualitative methods are also used in combination with quantitative methods in mixed method designs for convergence, complementarity, expansion, development, and sampling. Rigorously applied qualitative methods offer great potential in contributing to the scientific foundation of mental health services research. PMID:25350675

    Directory of Open Access Journals (Sweden)

    Mrosek M.

    2011-09-01

    Full Text Available An extension of the air-and exhaust-system with a low-pressure EGR has the potential to significantly reduce the NOx emissions. Besides a cooled high-pressure EGR and the turbocharger with variable geometry turbine, the low-pressure EGR introduces an additional degree of freedom to control the cylinder charge. This increasing complexity of the air system can be handled with model based control structures and a model based controller calibration. Its static and dynamic properties are investigated. Besides the static couplings in the classical air path, additional couplings appear. A decentralised gain scheduled PI(D-control approach is chosen to control the variables air mass flow rate, high-pressure EGR mass flow rate and charge air pressure. An automated controller calibration, based on a semi-physical mean value model of reduced complexity, is presented. The controller maps depend on the engine operation point and are calibrated by a local linearisation of the semi-physical model. Further, a semi-physical control is capable to almost solely control the air mass flow rate via the low-pressure EGR actuators. This control implicitly accounts for couplings between charge air pressure, high-pressure EGR and the low-pressure EGR system. Finally testbed results are shown. Une extension du système d’air et d’échappement au moyen d’EGR basse pression peut potentiellement réduire significativement les émissions de NOx. À côté de l’EGR haute pression refroidi et du turbocompresseur à turbine à géométrie variable, l’EGR basse pression introduit un degré de liberté supplémentaire pour contrôler la charge du cylindre. Cette complexité croissante du système d’air peut être traitée à l’aide de structures de contrôle et d’un étalonnage de régulateur basés sur des modèles. Ses propriétés statiques et dynamiques sont étudiées. En dehors des couplages statiques dans la boucle d’air classique, des couplages

  17. Concurrent analysis: towards generalisable qualitative research.

    Science.gov (United States)

    Snowden, Austyn; Martin, Colin R

    2011-10-01

    This study develops an original method of qualitative analysis coherent with its interpretivist principles. The objective is to increase the likelihood of achieving generalisability and so improve the chance of the findings being translated into practice. Good qualitative research depends on coherent analysis of different types of data. The limitations of existing methodologies are first discussed to justify the need for a novel approach. To illustrate this approach, primary evidence is presented using the new methodology. The primary evidence consists of a constructivist grounded theory of how mental health nurses with prescribing authority integrate prescribing into practice. This theory is built concurrently from interviews, reflective accounts and case study data from the literature. Concurrent analysis. Ten research articles and 13 semi-structured interviews were sampled purposively and then theoretically and analysed concurrently using constructivist grounded theory. A theory of the process of becoming competent in mental health nurse prescribing was generated through this process. This theory was validated by 32 practising mental health nurse prescribers as an accurate representation of their experience. The methodology generated a coherent and generalisable theory. It is therefore claimed that concurrent analysis engenders consistent and iterative treatment of different sources of qualitative data in a manageable manner. This process supports facilitation of the highest standard of qualitative research. Concurrent analysis removes the artificial delineation of relevant literature from other forms of constructed data. This gives researchers clear direction to treat qualitative data consistently raising the chances of generalisability of the findings. Raising the generalisability of qualitative research will increase its chances of informing clinical practice. © 2010 Blackwell Publishing Ltd.

  18. The Epistemology of Qualitative Research

    Directory of Open Access Journals (Sweden)

    Howard S. Becker

    2014-07-01

    Full Text Available This article discusses questions that are relevant to the epistemology of qualitative research. In order to do so, the presumed dichotomy between qualitative and quantitative research is discussed and challenged. According to the author, the similarities between these methods are more relevant than its differences. Both methods strive to describe the social reality and thus have the same epistemological basis, even though they emphasize different questions. To shed light in such dichotomy, the author explores the origins of epistemology as a discipline and its philosophical character. Finally, the particularities and advantages of qualitative research are discussed, especially ethnography and field research, through an analysis of some of its main aspects for observing social reality: its focus on the point of view of the actor; the observation of the everyday world and the full and thick description.

    Reviewing literature in qualitative research can be challenging in terms of why, when, where, and how we should access third-party sources in our work, especially for novice qualitative researchers. As a pragmatic solution, we suggest qualitative researchers utilize research literature in four functional ways: (a) define the phenomenon in…

    Situated in a research-intensive School of Nursing, the Advanced Qualitative Collective (AQC) provides an innovative educational forum for the study of qualitative research by doctoral and postdoctoral scholars. This long-standing collective is guided by a faculty facilitator using a collaborative co-learning approach to address individual and group needs, from the conception of research projects through dissemination of completed qualitative research. This article describes the dynamics of the AQC and the ways a co-created pedagogical entity supports professional development among its diverse members. The informal, participatory style, and dynamic content used by the AQC resists a course structure typical of doctoral education in health sciences, and promotes engagement and self-direction. The AQC provides opportunities for members to examine theoretical frameworks and methodologies rarely addressed within a positivism-dominant learning environment while simultaneously serving as an alternative exemplar for the pedagogy of research.

  13. Enhancing the quality and credibility of qualitative analysis.

    Patton, M Q

    1999-12-01

    Varying philosophical and theoretical orientations to qualitative inquiry remind us that issues of quality and credibility intersect with audience and intended research purposes. This overview examines ways of enhancing the quality and credibility of qualitative analysis by dealing with three distinct but related inquiry concerns: rigorous techniques and methods for gathering and analyzing qualitative data, including attention to validity, reliability, and triangulation; the credibility, competence, and perceived trustworthiness of the qualitative researcher; and the philosophical beliefs of evaluation users about such paradigm-based preferences as objectivity versus subjectivity, truth versus perspective, and generalizations versus extrapolations. Although this overview examines some general approaches to issues of credibility and data quality in qualitative analysis, it is important to acknowledge that particular philosophical underpinnings, specific paradigms, and special purposes for qualitative inquiry will typically include additional or substitute criteria for assuring and judging quality, validity, and credibility. Moreover, the context for these considerations has evolved. In early literature on evaluation methods the debate between qualitative and quantitative methodologists was often strident. In recent years the debate has softened. A consensus has gradually emerged that the important challenge is to match appropriately the methods to empirical questions and issues, and not to universally advocate any single methodological approach for all problems.

    Qualitative research is increasingly recognized and valued and its unique place in nursing research is highlighted by many. Despite this, some nurse researchers continue to raise epistemological issues about the problems of objectivity and the validity of qualitative research findings. This paper explores the issues relating to the representativeness or credibility of qualitative research findings. It therefore critiques the existing distinct philosophical and methodological positions concerning the trustworthiness of qualitative research findings, which are described as follows: quantitative studies should be judged using the same criteria and terminology as quantitative studies; it is impossible, in a meaningful way, for any criteria to be used to judge qualitative studies; qualitative studies should be judged using criteria that are developed for and fit the qualitative paradigm; and the credibility of qualitative research findings could be established by testing out the emerging theory by means of conducting a deductive quantitative study. The authors conclude by providing some guidelines for establishing the credibility of qualitative research findings.

    Full Text Available Existing discussion of the relationships between globalization, communication research, and qualitative methods emphasizes two images: the challenges posed by globalization to existing communication theory and research methods, and the impact of post-colonial politics and ethics on qualitative research. We draw in this paper on a third image – qualitative research methods as artifacts of globalization – to explore the globalization of qualitative communication research methods. Following a review of literature which tentatively models this process, we discuss two case studies of qualitative research in the disciplinary subfields of intercultural communication and media audience studies. These cases elaborate the forces which influence the articulation of national, disciplinary, and methodological identities which mediate the globalization of qualitative communication research methods.

    Science.gov (United States)

    2009-01-01

    Background The knowledge and use of qualitative description as a qualitative research approach in health services research is limited. The aim of this article is to discuss the potential benefits of a qualitative descriptive approach, to identify its strengths and weaknesses and to provide examples of use. Discussion Qualitative description is a useful qualitative method in much medical research if you keep the limitations of the approach in mind. It is especially relevant in mixed method research, in questionnaire development and in research projects aiming to gain firsthand knowledge of patients', relatives' or professionals' experiences with a particular topic. Another great advantage of the method is that it is suitable if time or resources are limited. Summary As a consequence of the growth in qualitative research in the health sciences, researchers sometimes feel obliged to designate their work as phenomenology, grounded theory, ethnography or a narrative study when in fact it is not. Qualitative description might be a useful alternative approach to consider. PMID:19607668

  20. The myth of induction in qualitative nursing research.

    Science.gov (United States)

    Bergdahl, Elisabeth; Berterö, Carina M

    2015-04-01

    In nursing today, it remains unclear what constitutes a good foundation for qualitative scientific inquiry. There is a tendency to define qualitative research as a form of inductive inquiry; deductive practice is seldom discussed, and when it is, this usually occurs in the context of data analysis. We will look at how the terms 'induction' and 'deduction' are used in qualitative nursing science and by qualitative research theorists, and relate these uses to the traditional definitions of these terms by Popper and other philosophers of science. We will also question the assertion that qualitative research is or should be inductive. The position we defend here is that qualitative research should use deductive methods. We also see a need to understand the difference between the creative process needed to create theory and the justification of a theory. Our position is that misunderstandings regarding the philosophy of science and the role of inductive and deductive logic and science are still harming the development of nursing theory and science. The purpose of this article is to discuss and reflect upon inductive and deductive views of science as well as inductive and deductive analyses in qualitative research. We start by describing inductive and deductive methods and logic from a philosophy of science perspective, and we examine how the concepts of induction and deduction are often described and used in qualitative methods and nursing research. Finally, we attempt to provide a theoretical perspective that reconciles the misunderstandings regarding induction and deduction. Our conclusion is that openness towards deductive thinking and testing hypotheses is needed in qualitative nursing research. We must also realize that strict induction will not create theory; to generate theory, a creative leap is needed. © 2014 John Wiley & Sons Ltd.

    2010-06-01

    The role of theory in qualitative research is often underplayed but it is relevant to the quality of such research in three main ways. Theory influences research design, including decisions about what to research and the development of research questions. Theory underpins methodology and has implications for how data are analyzed and interpreted. Finally, theory about a particular health issue may be developed, contributing to what is already known about the topic that is the focus of the study. This paper will critically consider the role of theory in qualitative primary care research in relation to these three areas. Different approaches to qualitative research will be drawn upon in order to illustrate the ways in which theory might variably inform qualitative research, namely generic qualitative research, grounded theory and discourse analysis. The aim is to describe and discuss key issues and provide practical guidance so that researchers are more aware of the role theory has to play and the importance of being explicit about how theory affects design, analysis and the quality of qualitative research.

    Researchers sometimes undertake qualitative research with randomised controlled trials (RCTs) of health interventions. To systematically explore how qualitative research is being used with trials and identify ways of maximising its value to the trial aim of providing evidence of effectiveness of health interventions. A sequential mixed methods study with four components. (1) Database search of peer-reviewed journals between January 2008 and September 2010 for articles reporting the qualitative research undertaken with specific trials, (2) systematic search of database of registered trials to identify studies combining qualitative research and trials, (3) survey of 200 lead investigators of trials with no apparent qualitative research and (4) semistructured telephone interviews with 18 researchers purposively sampled from the first three methods. Qualitative research was undertaken with at least 12% of trials. A large number of articles reporting qualitative research undertaken with trials (n=296) were published between 2008 and 2010. A total of 28% (82/296) of articles reported qualitative research undertaken at the pre-trial stage and around one-quarter concerned drugs or devices. The articles focused on 22 aspects of the trial within five broad categories. Some focused on more than one aspect of the trial, totalling 356 examples. The qualitative research focused on the intervention being trialled (71%, 254/356), the design and conduct of the trial (15%, 54/356), the outcomes of the trial (1%, 5/356), the measures used in the trial (3%, 10/356), and the health condition in the trial (9%, 33/356). The potential value of the qualitative research to the trial endeavour included improving the external validity of trials and facilitating interpretation of trial findings. This value could be maximised by using qualitative research more at the pre-trial stage and reporting findings with explicit attention to the implications for the trial endeavour. During interviews

    Full Text Available Les introductions de Salmonidés ont été importantes au cours des 60 dernières années dans les lacs et ruisseaux d'altitude des Hautes-Pyrénées. Six espèces de Salmonidés ont été introduites dans des milieux qui, pour la plupart, étaient vierges de populations piscicoles : la truite commune (Salmo trutta L., la truite arc-en-ciel (Oncorhynchus mykiss Walbaum, l'omble de fontaine (Salvelinus fontinalis Mitchill, l'omble chevalier (Salvelinus alpinus L., le cristivomer (Salvelinus namaycush Walbaum et le splake (Salvelinus fontinalis x Salvelinus namaycush. Dans de très nombreux cas, ces introductions ont abouti à des acclimatations. En revanche, les naturalisations sont beaucoup plus rares. Seules les espèces lacustres (cristivomer et omble chevalier se sont naturalisées dans la majorité des lacs où elles ont été introduites. Les conditions de reproduction constituent le facteur clé permettant d'expliquer la naturalisation des espèces. En ruisseau, il faut y ajouter la compétition avec l'espèce indigène (la truite commune, la pression halieutique ainsi que les conditions hivernales très rigoureuses. Les incidences écologiques des introductions sur les populations de truites communes indigènes sont faibles. En revanche, elles ne sont pas négligeables pour les populations de batraciens. Cette politique d'introduction a largement participé au développement de l'halieutisme dans ces milieux d'altitude. En cela, les introductions ont parfaitement répondu aux objectifs halieutiques qu'on leur avait fixés. L'acquisition de connaissances sur l'ensemble de la chaîne pyrénéenne constitue aujourd'hui une étape incontournable pour une politique de gestion globale des introductions.

  9. Reliability and Validity of Qualitative and Operational Research Paradigm

    2008-01-01

    Full Text Available Both qualitative and quantitative paradigms try to find the same result; the truth. Qualitative studies are tools used in understanding and describing the world of human experience. Since we maintain our humanity throughout the research process, it is largely impossible to escape the subjective experience, even for the most experienced of researchers. Reliability and Validity are the issue that has been described in great deal by advocates of quantitative researchers. The validity and the norms of rigor that are applied to quantitative research are not entirely applicable to qualitative research. Validity in qualitative research means the extent to which the data is plausible, credible and trustworthy; and thus can be defended when challenged. Reliability and validity remain appropriate concepts for attaining rigor in qualitative research. Qualitative researchers have to salvage responsibility for reliability and validity by implementing verification strategies integral and self-correcting during the conduct of inquiry itself. This ensures the attainment of rigor using strategies inherent within each qualitative design, and moves the responsibility for incorporating and maintaining reliability and validity from external reviewers’ judgments to the investigators themselves. There have different opinions on validity with some suggesting that the concepts of validity is incompatible with qualitative research and should be abandoned while others argue efforts should be made to ensure validity so as to lend credibility to the results. This paper is an attempt to clarify the meaning and use of reliability and validity in the qualitative research paradigm.

    Full Text Available This paper discusses the development of a 14-inch ID high-pressure hybrid riser (10 000 psi for surface BOP drilling in ultra-deep water (10 000 ft. The high-pressure hybrid riser system is obtained by adapting and combining two existing technologies, previously developed by the IFP for other applications: – the Clip connector, a double breech-block type connector to provide a quick and safe connection for riser joints; – hybrid pipe technology, a steel pipe hoop-wound with tapes of carbon fibers impregnated with polyamide thermoplastic resin. IFP has developed a new 14-inch ID HP Clip connector for the hybrid riser application. The connector is capable of withstanding a 2.8 million pound tension and a 10 000 psi operating pressure. In addition, a 16-inch nominal OD hybrid riser pipe has been designed to replace the steel riser pipe with a thinnerwalled hoop-wound steel pipe. The significant weight savings that can be achieved with the hybrid riser pipe make it possible to design an effective riser architecture to withstand the high pressure and deep water requirements. Pursuant to design studies, a 14-inch ID prototype assembly consisting of two hybrid riser pipe sections with a high-pressure Clip connector was manufactured. A test program, including burst and collapse tests as well as cyclic fatigue testing, was formulated and carried out to qualify the performance of the Clip connector and hybrid riser pipe system. Completion of hybrid pipe additional fatigue testing and realization of a scale-one field testing of the hybrid riser are considered as the next steps of the project. To date, the main test results (burst, collapse, fatigue resistance confirm that the Clip connector and the hybrid pipe technologies are well suited for ultra-deep sea drilling with a surface BOP. However, the fatigue resistance of hybrid riser pipes still needs to be better characterized. Cet article présente le développement d’un riser hybride 14”ID haute

    The value of using qualitative research within or alongside randomised controlled trials (RCTs) is becoming more widely accepted. Qualitative research may be conducted concurrently with pilot or full RCTs to understand the feasibility and acceptability of the interventions being tested, or to improve trial conduct. Clinical Trials Units (CTUs) in the United Kingdom (UK) manage large numbers of RCTs and, increasingly, manage the qualitative research or collaborate with qualitative researchers external to the CTU. CTUs are beginning to explicitly manage the process, for example, through the use of standard operating procedures for designing and implementing qualitative research with trials. We reviewed the experiences of two UK Clinical Research Collaboration (UKCRC) registered CTUs of conducting qualitative research concurrently with RCTs. Drawing on experiences gained from 15 studies, we identify the potential for the qualitative research to undermine the successful completion or scientific integrity of RCTs. We show that potential problems can arise from feedback of interim or final qualitative findings to members of the trial team or beyond, in particular reporting qualitative findings whilst the trial is on-going. The problems include: We make recommendations for improving the management of qualitative research within CTUs. Copyright © 2014. Published by Elsevier Inc.

    Manish K. Thakur

    2008-10-01

    Full Text Available The book fruitfully combines discussions on qualitative research methods with the craft of academic writing. While detailing different stages involved in qualitative research, it accords appreciable attention to the fundamental epistemological premises of different qualitative research genres. Yet, its central concern is to demonstrate ways and means to manage researcher’s subjectivity in the writing of qualitative research. The book looks at the act of writing as crucial to the twin concerns of rigor and validity in qualitative research. It privileges writing as an important methodological resource that qualitative researchers employ to make the workings of their research procedures transparent and establish their accountability in relation to specificities of a given research setting. Given this focus, the eight chapters of the book discuss at length issues such as authorial voice, the trials and tribulations of transition from data to written study, the reflexivity of the researcher as writer, and the demanding expectations of cautious detachment in reporting the people, setting, and the worlds and sensitivities that are part of any qualitative research enterprise.

    Full Text Available Social media technologies have attracted substantial attention among many types of users including researchers who have published studies for several years. This article presents an overview of trends in qualitative and mixed methods social media research literature published from 2007 through 2013. A collection of 229 qualitative studies were identified through a systematic literature review process. A subset of 55 of these articles report studies involving a combination of qualitative and quantitative methods. Articles were reviewed, analyzed, and coded through a qualitative content analysis approach. Overall trends are presented with respect to the entire collection of articles followed by an analysis of mixed methods research approaches identified in the subset of 55 studies. The most commonly used research approaches involved collecting data from people through interview, focus group, and survey methodologies. Content analysis was the second most commonly used approach whereby researchers use Facebook posts, Tweets (Twitter posts, YouTube videos, or other social media content as a data source. Many of the studies involving combinations of quantitative and qualitative data followed a design resembling Creswell and Plano Clark’s basic mixed methods typology (e.g., convergent parallel, explanatory sequential, and exploratory sequential.

    The use of qualitative research methodology is well established for data generation within healthcare research generally and clinical pharmacy research specifically. In the past, qualitative research methodology has been criticized for lacking rigour, transparency, justification of data collection and analysis methods being used, and hence the integrity of findings. Demonstrating rigour in qualitative studies is essential so that the research findings have the "integrity" to make an impact on practice, policy or both. Unlike other healthcare disciplines, the issue of "quality" of qualitative research has not been discussed much in the clinical pharmacy discipline. The aim of this paper is to highlight the importance of rigour in qualitative research, present different philosophical standpoints on the issue of quality in qualitative research and to discuss briefly strategies to ensure rigour in qualitative research. Finally, a mini review of recent research is presented to illustrate the strategies reported by clinical pharmacy researchers to ensure rigour in their qualitative research studies.

This study aims to develop a framework for reporting the synthesis of qualitative health research. Methods We conducted a comprehensive search for guidance and reviews relevant to the synthesis of qualitative research, methodology papers, and published syntheses of qualitative health research in MEDLINE, Embase, CINAHL and relevant organisational websites to May 2011. Initial items were generated inductively from guides to synthesizing qualitative health research. The preliminary checklist was piloted against forty published syntheses of qualitative research, purposively selected to capture a range of year of publication, methods and methodologies, and health topics. We removed items that were duplicated, impractical to assess, and rephrased items for clarity. Results The Enhancing transparency in reporting the synthesis of qualitative research (ENTREQ) statement consists of 21 items grouped into five main domains: introduction, methods and methodology, literature search and selection, appraisal, and synthesis of findings. Conclusions The ENTREQ statement can help researchers to report the stages most commonly associated with the synthesis of qualitative health research: searching and selecting qualitative research, quality appraisal, and methods for synthesising qualitative findings. The synthesis of qualitative research is an expanding and evolving methodological area and we would value feedback from all stakeholders for the continued development and extension of the ENTREQ statement.

  17. What role for qualitative methods in randomized experiments?

    DEFF Research Database (Denmark)

    Prowse, Martin; Camfield, Laura

    2009-01-01

    The vibrant debate on randomized experiments within international development has been slow to accept a role for qualitative methods within research designs. Whilst there are examples of how 'field visits' or descriptive analyses of context can play a complementary, but secondary, role...... history interviews have advantages over other qualitative methods, and offers one alternative to the conventional survey tool....... to quantitative methods, little attention has been paid to the possibility of randomized experiments that allow a primary role to qualitative methods. This paper assesses whether a range of qualitative methods compromise the internal and external validity criteria of randomized experiments. It suggests that life...

  20. Reporting Qualitative Research: Standards, Challenges, and Implications for Health Design.

    Peditto, Kathryn

    2018-04-01

    This Methods column describes the existing reporting standards for qualitative research, their application to health design research, and the challenges to implementation. Intended for both researchers and practitioners, this article provides multiple perspectives on both reporting and evaluating high-quality qualitative research. Two popular reporting standards exist for reporting qualitative research-the Consolidated Criteria for Reporting Qualitative Research (COREQ) and the Standards for Reporting Qualitative Research (SRQR). Though compiled using similar procedures, they differ in their criteria and the methods to which they apply. Creating and applying reporting criteria is inherently difficult due to the undefined and fluctuating nature of qualitative research when compared to quantitative studies. Qualitative research is expansive and occasionally controversial, spanning many different methods of inquiry and epistemological approaches. A "one-size-fits-all" standard for reporting qualitative research can be restrictive, but COREQ and SRQR both serve as valuable tools for developing responsible qualitative research proposals, effectively communicating research decisions, and evaluating submissions. Ultimately, tailoring a set of standards specific to health design research and its frequently used methods would ensure quality research and aid reviewers in their evaluations.

    Qualitative research has had a significant impact within rehabilitation science over time. During the past 20 years the number of qualitative studies published per year in Disability and Rehabilitation has markedly increased (from 1 to 54). In addition, during this period there have been significant changes in how qualitative research is conceptualized, conducted, and utilized to advance the field of rehabilitation. The purpose of this article is to reflect upon the progress of qualitative research within rehabilitation to date, to explicate current opportunities and challenges, and to suggest future directions to continue to strengthen the contribution of qualitative research in this field. Relevant literature searches were conducted in electronic data bases and reference lists. Pertinent literature was examined to identify current opportunities and challenges for qualitative research use in rehabilitation and to identify future directions. Six key areas of opportunity and challenge were identified: (a) paradigm shifts, (b) advancements in methodology, (c) emerging technology, (d) advances in quality evaluation, (e) increasing popularity of mixed methods approaches, and (f) evolving approaches to knowledge translation. Two important future directions for rehabilitation are posited: (1) advanced training in qualitative methods and (2) engaging qualitative communities of research. Qualitative research is well established in rehabilitation and has an important place in the continued growth of this field. Ongoing development of qualitative researchers and methods are essential. Implications for Rehabilitation Qualitative research has the potential to improve rehabilitation practice by addressing some of the most pervasive concerns in the field such as practitioner-client interaction, the subjective and lived experience of disability, and clinical reasoning and decision making. This will serve to better inform those providing rehabilitation services thereby benefiting

    Considerable time and resources are allocated to carry out qualitative research. The purpose of our study was to evaluate the availability of qualitative research on women's health screening and assess its influence on screening practice guidelines in the United States, Canada, and the United Kingdom. Medline, CINHAL, and WEB of Science databases were used to identify the availability of qualitative research conducted in the past 15 years on 3 different women's health screening topics: cervical cancer screening, breast cancer screening, and prenatal first-trimester screening. Key national practice guidelines on women's health screening were selected using the National Guideline Clearinghouse web site. Bibliometric analysis was used to determine the frequency of qualitative references cited in the guidelines. A total of 272 qualitative research papers on women's health screening was identified: 109 on cervical cancer screening, 104 on breast cancer screening, and 59 on prenatal first-trimester screening. The qualitative studies focused on health care provider perspectives as well as ethical, ethnographic, psychological, and social issues surrounding screening. Fifteen national clinical practice guidelines on women's health screening were identified. A total of 943 references was cited, only 2 of which comprised of qualitative research cited by only 1 clinical practice guideline. Although there is considerable qualitative research that has been carried out on women's health screening, its incorporation into clinical practice guidelines is minimal. Further exploration of the disconnect between the two is important for enhancing knowledge translation of qualitative research within clinical practice. Copyright © 2014 Mosby, Inc.

  7. Qualitative treatment of three-nucleon properties

    International Nuclear Information System (INIS)

    Efimov, V.

    1981-01-01

    An attempt is made at consistent qualitative treatment of the three-nucleon system. The approach used is based on the physical concept of effective three-nucleon long-range interaction resulting from the existence of the deuteron and the virtual singlet deuteron. Within the framework of the approach, a qualitative treatment of the triton properties, nucleon-deuteron scattering, and triton-disintegration reactions is carried out. The following topics are dealt with: the Phillips line, the triton D-wave admixture, the doublet effective range of the n-d scattering, the triton virtual state, the anomaly of the n-d elastic cross section near the three-body threshold, and the partial cross sections of the inelastic n-d scattering and of the triton photo- and electrodisintegration. The discussion of these topics includes the evaluation of three-nucleon parameters and the qualitative interpretation of experimental data and calculation results; some predictions are also made. The results of our analysis lead to the conclusion that the concept of effective three-nucleon long-range interaction can indeed serve as grounds for consistent qualitative treatment of the three-nucleon phenomena.

    2016-06-01

    In this paper we reflect on current trends and anticipate future prospects regarding qualitative research in Psychology. We highlight various institutional and disciplinary obstacles to qualitative research diversity, complexity and quality. At the same time, we note some causes for optimism, including publication breakthroughs and vitality within the field. The paper is structured into three main sections which consider: 1) the positioning of qualitative research within Psychology; 2) celebrating the different kinds of knowledge produced by qualitative research; and 3) implementing high quality qualitative research. In general we accentuate the positive, recognising and illustrating innovative qualitative research practices which generate new insights and propel the field forward. We conclude by emphasising the importance of research training: for qualitative research to flourish within Psychology (and beyond), students and early career researchers require more sophisticated, in-depth instruction than is currently offered.

  9. Finding Qualitative Research Evidence for Health Technology Assessment.

    DeJean, Deirdre; Giacomini, Mita; Simeonov, Dorina; Smith, Andrea

    2016-08-01

    Health technology assessment (HTA) agencies increasingly use reviews of qualitative research as evidence for evaluating social, experiential, and ethical aspects of health technologies. We systematically searched three bibliographic databases (MEDLINE, CINAHL, and Social Science Citation Index [SSCI]) using published search filters or "hedges" and our hybrid filter to identify qualitative research studies pertaining to chronic obstructive pulmonary disease and early breast cancer. The search filters were compared in terms of sensitivity, specificity, and precision. Our screening by title and abstract revealed that qualitative research constituted only slightly more than 1% of all published research on each health topic. The performance of the published search filters varied greatly across topics and databases. Compared with existing search filters, our hybrid filter demonstrated a consistently high sensitivity across databases and topics, and minimized the resource-intensive process of sifting through false positives. We identify opportunities for qualitative health researchers to improve the uptake of qualitative research into evidence-informed policy making. © The Author(s) 2016.

  10. Bridging Conceptions of Quality in Moments of Qualitative Research

    Directory of Open Access Journals (Sweden)

    Michael John Ravenek

    2013-02-01

    Full Text Available Quality assessment in qualitative research has been, and remains, a contentious issue. The qualitative literature contains a diversity of opinions on definitions of and criteria for quality. This article attempts to organize this diversity, drawing on several examples of existing quality criteria, into four main approaches: qualitative as quantitative criteria, paradigm-specific criteria, individualized assessment, and bridging criteria. These different approaches can be mapped onto the historical transitions, or moments, in qualitative research presented by Denzin and Lincoln and, as such, they are presented alongside the various criteria reviewed. Socio-political conditions that have led us to a fractured future, where the value and significance of qualitative work may be marginalized, support the adoption of bridging criteria. These broadly applicable criteria provide means to assess quality and can be flexibly applied among the diversity of qualitative approaches used by researchers. Five categories that summarize the language used within bridging criteria are presented as a means to move forward in developing an approach to quality assessment that fosters communication and connections within the diversity of qualitative research, while simultaneously respecting and valuing paradigmatic and methodological diversity.

    2008-07-01

    It is not finally concluded how to standardize the use of qualitative research in the world. Qualitative researchers disagree with each other about this issue. As we know, there have been a large number of articles written in different ways about qualitative research due to the "flexibility", one of its features. Qualitative research is quite different from quantitative research which is easy to control its quality and quality assessment. A series of criteria has been set up for quantitative research. However qualitative research needs to be improved in these aspects, in which qualitative interviews are mostly used at home and abroad at present. Hence, it becomes an important and urgent issue for qualitative researchers to standardly control and assess the quality of qualitative interview.

  18. Review: Lyn Richards (2005. Handling Qualitative Data: A Practical Guide

    Directory of Open Access Journals (Sweden)

    Robert L. Miller

    2006-03-01

    Full Text Available Handling Qualitative Data: A Practical Guide is an introductory textbook covering all stages of qualitative research from the initial conceptualisation of a project, through data collection and analysis, to writing up. The author, Lyn RICHARDS, is a well-known developer of two key qualitative software analysis packages, NUD*IST and NVivo. While RICHARDS clearly advocates the use of qualitative analysis software, the text is "generic" and could be used in tandem with any qualitative software package. The book concentrates on practical advice about the use of software to manage and analyse qualitative data, and provides insights in these areas. The consideration of issues around team-based qualitative research is another strong point. However, due in part to its short length, the overall coverage of topics tends to be superficial. In itself, the book does not provide sufficient detailed support for a student who would like to use it as her/his main source of guidance for carrying out a qualitative research project.

    2011-06-01

    To appraise the quality of published qualitative research in dentistry and identify aspects of quality, which require attention in future research. Qualitative research studies on dental topics were appraised using the critical appraisal skills programme (CASP) appraisal framework for qualitative research. The percentage of CASP criteria fully met during the assessment was used as an indication of the quality of each paper. Individual criteria were not weighted. Forty-three qualitative studies were identified for appraisal of which 48% had a dental public health focus. Deficiencies in detail of reporting, research design, methodological rigour, presentation of findings, reflexivity, credibility of findings and relevance of study were identified. Problems with quality were apparent irrespective of journal impact factor, although papers from low impact factor journals exhibited the most deficiencies. Journals with the highest impact factors published the least qualitative research. The quality of much of the qualitative research published on dental topics is mediocre. Qualitative methods are underutilized in oral health research. If quality guidelines such as the CASP framework are used in the context of a thorough understanding of qualitative research design and data analysis, they can promote good practice and the systematic assessment of qualitative research. © 2010 John Wiley & Sons A/S.

  20. Qualitative methods in radiography research: a proposed framework

    International Nuclear Information System (INIS)

    Adams, J.; Smith, T.

    2003-01-01

    Introduction: While radiography is currently developing a research base, which is important in terms of professional development and informing practice and policy issues in the field, the amount of research published by radiographers remains limited. However, a range of qualitative methods offer further opportunities for radiography research. Purpose: This paper briefly introduces a number of key qualitative methods (qualitative interviews, focus groups, observational methods, diary methods and document/text analysis) and sketches one possible framework for future qualitative work in radiography research. The framework focuses upon three areas for study: intra-professional issues; inter-professional issues; and clinical practice, patient and health delivery issues. While the paper outlines broad areas for future focus rather than providing a detailed protocol for how individual pieces of research should be conducted, a few research questions have been chosen and examples of possible qualitative methods required to answer such questions are outlined for each area. Conclusion: Given the challenges and opportunities currently facing the development of a research base within radiography, the outline of key qualitative methods and broad areas suitable for their application is offered as a useful tool for those within the profession looking to embark upon or enhance their research career

    While vast opportunities for using qualitative methods exist within palliative care research, few studies provide practical advice for researchers and clinicians as a roadmap to identify and utilize such opportunities. To provide palliative care clinicians and researchers descriptions of qualitative methodology applied to innovative research questions relative to palliative care research and define basic concepts in qualitative research. Body: We describe three qualitative projects as exemplars to describe major concepts in qualitative analysis of early palliative care: (1) a descriptive analysis of clinician documentation in the electronic health record, (2) a thematic content analysis of palliative care clinician focus groups, and (3) a framework analysis of audio-recorded encounters between patients and clinicians as part of a clinical trial. This study provides a foundation for undertaking qualitative research within palliative care and serves as a framework for use by other palliative care researchers interested in qualitative methodologies.

    The utility of qualitative research findings in the health sciences has been the subject of considerable debate, particularly with the advent of qualitative systematic reviews in recent years. There has been a significant investment in the production of guidance to improve the reporting of quantitative research; however, comparatively little time has been spent on developing the same for qualitative research reporting. This paper sets out to examine the possibility of developing a framework for refereed journals to utilize when guiding authors on how to report the results of qualitative studies in the hope that this will improve the quality of reports and subsequently their inclusion in qualitative syntheses and guidelines to inform practice at the point of care. © 2014 Wiley Publishing Asia Pty Ltd.

  7. Qualitative versus quantitative assessment of cerebrovascular reserve capacity

    Okuguchi, Taku

    2000-01-01

    Quantitative studies of cerebral blood flow (CBF) combined with a acetazolamide (ACZ) challenge have defined a subgroup of patients with symptomatic carotid or middle cerebral artery (MCA) occlusive diseases who are at an increased risk for stroke. Recent reports suggest that qualitative CBF techniques could also define the same high-risk subgroup. To evaluate the accuracy of the qualitative method, we compared qualitative ratios with quantitative CBF data, obtained using iodine-123-N-isopropyl-p-iodoamphetamine (IMP) single-photon emission computed tomography (SPECT). We analyzed qualitative and quantitative IMP SPECT images for 50 patients with symptomatic carotid or middle cerebral artery occlusive diseases. Quantitative CBF data were measured by the autoradiographic technique. One region-of-interest within each hemisphere was within the MCA territory. Relative cerebrovascular reserve capacity (CVRC) obtained using qualitative images before and after the intravenous administration of 1 g of ACZ was defined as follows: ( ACZ C occl / ACZ C non )/( baseline C occl / baseline C non ). The threshold for abnormal relative CVRC was defined as less than 1.0. Quantitative CBF was considered abnormal when the response to ACZ (percent change) on the symptomatic side (absolute CVRC) was a decrease of more than 10%. Of 39 patients whose relative CVRC were considered abnormal, 29 (74%) were normal in absolute CVRC (i.e., false positive). Two of 12 (17%) who were not considered compromised by qualitative criteria had abnormal absolute CVRC (i.e., false negative). This study demonstrates that this important subgroup cannot be accurately defined with qualitative methodology. (author)

    2015-03-01

    This article documents the evolution of qualitative psychotherapy research over the past 3 decades. Clients' and therapists' accounts of their experiences in psychotherapy provide a window into the psychotherapy relationship and its mechanisms of change. A sizable body of literature has been generated that uses qualitative methods to collect and analyze these accounts and to shed light on the psychotherapy process. It notes changes in the field such as growing numbers of dissertations and publications using qualitative methods as well as a strengthening emphasis on qualitative research within graduate education and research funding bodies. Future recommendations include developing principles for practice from qualitative methods and conducting qualitative meta-analyses. Other recommendations include forming journal review policies that support the publication of qualitative research and that focus on coherence in adapting methods to meet research goals, in light of a study's characteristics and epistemological framework, rather than focusing on sets of procedures.

  12. Decision making in goverment tenders: A formalized qualitative model

    Directory of Open Access Journals (Sweden)

    Štěpán Veselý

    2012-01-01

    Full Text Available The paper presents a simple formalized qualitative model of government tenders (GTs. Qualitative models use just three values: Positive/Increasing, Zero/Constant and Negative/Decreasing. Such quantifiers of trends are the least information intensive. Qualitative models can be useful, since GT evaluation often includes such goals as e.g. efficiency of public purchasing, and variables as e.g. availability of relevant information or subjectivity of judgment, that are difficult to quantify. Hence, a significant fraction of available information about GTs is not of numerical nature, e.g. if availability of relevant information is decreasing then efficiency of public purchasing is decreasing as well. Such equationless relations are studied in this paper. A qualitative model of the function F(Goals, Variables is developed. The model has four goal functions, eight variables, and 39 equationless relations. The model is solved and seven solutions, i.e. scenarios are obtained. All qualitative states, including first and second qualitative derivatives with respect to time, of all variables are specified for each scenario. Any unsteady state behavior of the GT model is described by its transitional oriented graph. There are eight possible transitions among seven scenarios. No a priori knowledge of qualitative modeling is required on the reader’s part.

    A new cathode sputtering theory at high energy is presented which has been elaborated in taking in account the non-linearity of this phenomenon with the density of the impinging ions. This theory allows to predict the influence of target temperature on the rate of cathode sputtering. This influence is experimentally demonstrated.

  14. Researching collaboratively: implications for qualitative research and researchers.

    Often discussions about collaborative research, and collaboration generally, begin at the point of how to collaborate, who to collaborate with, and what to collaborate about. Rarely do they include equally important questions of why we are having discussions about collaboration, where such an impetus and emphasis is coming from, and how it connects to the contemporary political research context. In a recent editorial in Qualitative Health Research, Janice Morse highlighted the need for reflection about collaboration. This article responds to that call, providing reflections on collaboration, the imperative to collaborate, and what this all might mean for both qualitative research and qualitative researchers. I hope to stimulate new points of departure for thinking and action shaping collaborative research endeavors without-and just as crucially, within-qualitative research.

  15. Contributions of qualitative research to evidence-based practice in nursing

    Full Text Available AIM: This article aims to identify the contributions of qualitative research to evidence-based practice in nursing. BACKGROUND: Qualitative research dates back to the 1920s and 1930s, when anthropologists and sociologists used qualitative research methods to study human phenomena in naturalistic settings and from a holistic viewpoint. Afterwards, other subject matters, including nursing, adopted qualitative methods to answer their research questions. The restructuring of health care over the past decade has brought about increased accountability in nursing research. One method for increasing this accountability is evidence-based practice. METHOD: The method used was a search in the Cumulative Index to Nursing and Allied Health Literature database from 1999-present. The search resulted in 61 citations for evidence-based practice in nursing research; however, only 5 citations focused on evidence-based practice and qualitative research. FINDINGS: The authors' findings revealed six contributions of qualitative research to evidence-based practice: generation of hypotheses; development and validation of instruments; provision of context for evaluation; development of nursing interventions; development of new research questions; and application of Qualitative Outcome Analysis. CONCLUSION: Qualitative research makes important contributions to the quality of evidence-based practice.

    In the course of our supervisory work over the years, we have noticed that qualitative research tends to evoke a lot of questions and worries, so-called Frequently Asked Questions. This journal series of four articles intends to provide novice researchers with practical guidance for conducting high-quality qualitative research in primary care. By 'novice' we mean Master's students and junior researchers, as well as experienced quantitative researchers who are engaging in qualitative research for the first time. This series addresses their questions and provides researchers, readers, reviewers and editors with references to criteria and tools for judging the quality of papers reporting on qualitative research. This first article describes the key features of qualitative research, provides publications for further learning and reading, and gives an outline of the series.

    A sound knowledge of the nature of qualitative research, along with an appreciation of some special ethical considerations, is needed for rigorous reviews to be conducted. The overall character of qualitative research is described with an emphasis on the tendency of qualitative researchers to explore sensitive topics using theoretically informed methods. A number of specific features of qualitative that require additional ethical attention and awareness are also examined including the following: 1) participants are frequently quite vulnerable and require protection because the data collection methods, such as in-depth interviews, can delve into personally and politically charged matters; 2) naturalistic observation can raise concerns regarding privacy and consent; 3) the potential for the identifiability of the results of this research may require extra efforts to maintain confidentiality. Ultimately, Reseach Ethics Committee members must be knowledgeable about qualitative approaches to be able to assess the potential harms and benefits in a protocol carefully. Without this knowledge gaining ethics approval can be overly difficult for researchers and the best practices for protecting human participants can be overlooked.

    Triangulation refers to the use of multiple methods or data sources in qualitative research to develop a comprehensive understanding of phenomena (Patton, 1999). Triangulation also has been viewed as a qualitative research strategy to test validity through the convergence of information from different sources. Denzin (1978) and Patton (1999) identified four types of triangulation: (a) method triangulation, (b) investigator triangulation, (c) theory triangulation, and (d) data source triangulation. The current article will present the four types of triangulation followed by a discussion of the use of focus groups (FGs) and in-depth individual (IDI) interviews as an example of data source triangulation in qualitative inquiry.

    2013-01-01

    In this paper, we formulate a qualitative "linear" utility theory for lotteries in which uncertainty is expressed qualitatively using a Spohnian disbelief function. We argue that a rational decision maker facing an uncertain decision problem in which the uncertainty is expressed qualitatively should behave so as to maximize "qualitative expected utility." Our axiomatization of the qualitative utility is similar to the axiomatization developed by von Neumann and Morgenstern for probabilistic l...

    Cross-cultural research has become important in this postmodern world where many people have been made, and are still, marginalised and vulnerable by others in more powerful positions like colonial researchers. In this paper, I contend that qualitative research is particularly appropriate for cross-cultural research because it allows us to find answers which are more relevant to the research participants. Cross-cultural qualitative research must be situated within some theoretical frameworks....

    Inherent in the care provided to patients with cancer is an important psychosocial element which has been explored scientifically through qualitative research. The purpose of our study was to evaluate the availability of qualitative research in gynaecologic oncology and to measure its integration in gynaecologic oncology practice guidelines. We searched Medline, CINHAL, Scopus, and Web of Science databases to identify the availability of qualitative research conducted in the past 20 years on the three most prevalent gynaecologic cancers: endometrial, ovarian, and cervical cancer. National and international practice guidelines on management of gynaecologic cancers were selected using the National Guideline Clearinghouse website, the Society of Obstetricians and Gynaecologists of Canada website, and the Standards and Guidelines Evidence directory of cancer guidelines. Bibliometric analysis was used to determine the frequency of qualitative references cited in these guidelines. One hundred thirteen qualitative research papers on gynaecologic cancers were identified focusing on psychological impacts, social dynamics, and doctor-patient interactions during cancer treatment and recovery. Among the 15 national and international clinical practice guidelines identified on management of gynaecologic cancer, there were a total of 2272 references, and of these only three references citing qualitative research were identified (0.1%) in only one of the 15 practice guidelines. Although qualitative research is being carried out in gynaecologic oncology, its integration into clinical practice guidelines is essentially absent. Efforts to narrow the gap between qualitative research and clinical practice are essential in ensuring a comprehensive approach to the treatment of patients with gynaecologic cancer.

Les deux événements éruptifs sont d’âge Jurassique moyen pour les coulées de l’horizon B1 et d’âge Crétacé inférieur pour celles de l’horizon B2. Les roches sont caractérisées par un faciès des basaltes à olivines. La composition de leurs clinopyroxènes est marquée par deux tendances : augite au niveau des basaltes à olivine du B1 et diopside au niveau de ceux du B2. La composition géochimique sur roche totale dévoile le caractère transitionnel de ces roches. La relative dissimilitude géochimique signalée au niveau des basaltes des deux horizons peut être expliquée par un début du changement de la nature du magmatisme de la région en relation avec l’évolution géodynamique du domaine atlasique.

    Full Text Available In this article we examine the characteristics, challenges and added value of qualitative prison research in a Belgian context. As the many dynamics and challenges of qualitative research are often underreported in academic publications, we pay particular attention to the research processes and the pains and gains of qualitative prison research. Firstly, drawing on experiences from several prison studies, we describe the different steps of gaining access to the field as a constant process of negotiation. Secondly, we discuss some of the dilemmas of prison research based on two ethnographic studies of prison staff. We end with discussion of the value added by a qualitative research approach to facilitate understanding of what is at stake in prisons and how this fits with a critical research position.
