  1. Fair innings.

    2015-05-01

    In many societies, the aging of the population is becoming a major problem. This raises difficult issues for ethics and public policy. On what is known as the fair innings view, it is not impermissible to give lower priority to policies that primarily benefit the elderly. Philosophers have tried to justify this view on various grounds. In this article, I look at a consequentialist, a fairness-based, and a contractarian justification. I argue that all of them have implausible implications and fail to correspond to our moral intuitions. I end by outlining a different kind of consequentialist justification that avoids those implications and corresponds better to our considered moral judgments. PMID:24909449

    2015-01-01

    La survenue d'un épanchement péricardique au cours d'une hypothyroïdie est fréquente. Ce fait justifie la réalisation d'une échocardiographie lors du diagnostic et du suivi évolutif des hypothyroïdies. Les signes de mauvaise tolérance de cet épanchement sont rares et la constitution d'une tamponnade péricardique n'est que très rarement rapportée. Ce travail se base sur l’étude rétrospective de quatre cas de tamponnade cardiaque révélant une hypothyroïdie primaire. L’échocardiographie a permis de faire le diagnostic immédiat de la tamponnade. Orienté par l'aspect clinique, le diagnostic d'hypothyroïdie a été confirmé par dosage biologique. Le traitement a été à base de drainage péricardique chirurgical et d'hormonothérapie progressive, l’évolution a été favorable avec disparition de l’épanchement péricardique. Certaines particularités physiopathologiques, l'intérêt de l’échocardiographie et du drainage péricardique chirurgical, tant au plan diagnostique qu'au plan thérapeutique sont soulignés.

  11. L’alimentation des enfants ayant une déficience neurologique

    PubMed Central

    2009-01-01

    La malnutrition, qu’il s’agisse de sous-alimentation ou de suralimentation, est courante chez les enfants ayant une déficience neurologique. Les besoins en énergie sont difficiles à définir au sein de cette population hétérogène. De plus, on manque d’information sur ce qui constitue la croissance normale chez ces enfants. Des facteurs non nutritionnels peuvent influer sur la croissance, mais des facteurs nutritionnels, tels qu’un apport calorique insuffisant, des pertes excessives d’éléments nutritifs et un métabolisme énergétique anormal, contribuent également au retard de croissance de ces enfants. La malnutrition est liée à une importante morbidité, tandis que la réadaptation nutritionnelle améliore l’état de santé global. Le soutien nutritionnel doit faire partie intégrante de la prise en charge des enfants ayant une déficience nutritionnelle et viser non seulement à améliorer l’état nutritionnel, mais également la qualité de vie des patients et de leur famille. Au moment d’envisager une intervention nutritionnelle, il faut tenir compte du dysfonctionnement oromoteur, du reflux gastro-œsophagien et de l’aspiration pulmonaire, et une équipe multidisciplinaire doit se concerter. Il faut repérer rapidement les enfants vulnérables à des troubles nutritionnels et procéder à une évaluation de leur état nutritionnel au moins une fois par année, et plus souvent chez les nourrissons et les jeunes enfants ou chez les enfants qui risquent de souffrir de malnutrition. Il faut optimiser l’apport oral s’il est sécuritaire, mais entreprendre une alimentation entérale chez les enfants ayant un dysfonctionnement oromoteur qui provoque une aspiration marquée ou chez ceux qui sont incapables de maintenir un état nutritionnel suffisant au moyen de l’apport oral. Il faut réserver l’alimentation par sonde nasogastrique aux interventions à court terme, mais si une intervention nutritionnelle prolongée s

  18. A fair test of the fair innings?

    PubMed

    Oliver, Adam

    2009-01-01

    Priority setting in health care under conventional rules of health economic evaluation is based upon the ethos of attempting to maximize post-treatment health gain given available health care resources. In his later years, Alan Williams advocated the "fair innings argument,'' which balances differences in whole lifetime experiences of health with differences in post-treatment outcomes when prioritizing people for health care. This article reports a study that presented respondents with a number of abstract health care decision contexts in an attempt to test the extent to which post-treatment health maximization, the fair innings argument, or, indeed other "decision rules,'' are evident in the respondents' answers. The results indicate that the most commonly observed decision rule differs substantially across health care contexts, and therefore imply that rather than pursue an overarching decision rule, it may be more appropriate to vary the rule according to the particular health care decision context under consideration.

    Ortega, Jason M.; Salari, Kambiz; McCallen, Rose

    2010-11-09

    A vehicle underbody fairing apparatus for reducing aerodynamic drag caused by a vehicle wheel assembly, by reducing the size of a recirculation zone formed under the vehicle body immediately downstream of the vehicle wheel assembly. The fairing body has a tapered aerodynamic surface that extends from a front end to a rear end of the fairing body with a substantially U-shaped cross-section that tapers in both height and width. Fasteners or other mounting devices secure the fairing body to an underside surface of the vehicle body, so that the front end is immediately downstream of the vehicle wheel assembly and a bottom section of the tapered aerodynamic surface rises towards the underside surface as it extends in a downstream direction.

    NASA Astrophysics Data System (ADS)

    Kester, Oliver; Spiller, Peter; Stoecker, Horst

    FAIR -- the Facility for Antiproton and Ion Research in Europe -- constructed at GSI Helmholtzzentrum für Schwerionenforschung GmbH in Darmstadt comprises an international centre of heavy ion accelerators that will drive heavy ion and antimatter research (FBTR, 2006). FAIR will provide worldwide unique accelerator and experimental facilities allowing a large variety of fore-front research in physics and applied science. FAIR will deliver antiproton and ion beams of unprecedented intensities and qualities. The main part of the FAIR facility is a sophisticated and cost efficient accelerator system, which delivers parallel beams to different experiments of the FAIR experimental collaborations -- APPA, NuSTAR, CBM and PANDA. The accelerated primary beams will then be employed to create new, often highly exotic particles in a series of parallel experimental programs. Experiments with exotic particles will explore fundamental processes which are expected to have taken place in the early phases and still happen in the on-going evolution of the Universe. These processes produced the basic constituents of matter and overall structure we observe today...

  4. Fairness in technological design.

    PubMed

    Shelley, Cameron

    2012-12-01

    This paper addresses an important multi-disciplinary issue of current interest, that is, the implications of technological design for fairness. A visual, graphical methodology centered on the Taylor-Russell diagram is proposed to address this issue. The Taylor-Russell diagram helps to identify and explore ways in which predictions built into designs can pit the interests of different constituencies against one another. The configuration of the design represents a trade-off between the interests of the communities involved. Whether or not the trade-off is appropriate constitutes a problem of fairness or distributive justice. The breadth of this methodology is supported by a diversity of examples analyzed. These include a surveillance system, an automotive safety system, a civic information system, and the international food distribution system. These examples provide models for application of the methodology to the analysis of designs in further areas of concern. Limitations of the methodology are also discussed. While it helps to identify and clarify issues of fairness in technology design, the methodology does not provide a general theory of fairness, nor can it provide fair solutions to such issues without appeal to further principles or concepts.

    Adjacent to the existing accelerator complex of the GSI Helmholtz Centre for Heavy Ion Research at Darmstadt, Germany, the Facility for Antiproton and Ion Research (FAIR) substantially expands research goals and technical possibilities. It will provide worldwide unique accelerator and experimental facilities allowing for a large variety of unprecedented fore-front research in hadron, nuclear and atomic physics as well as applied sciences which will be described briefly in this paper. The start version of FAIR, the so-called Modularized Start Version, will deliver first beams in 2017/2018. As an example the paper presents research efforts on strangeness at FAIR using heavy ion collisions, exotic nuclei from fragmentation and antiprotons to tackle various topics in this area. In particular hypernuclei and metastable exotic multi-hypernuclear objects will be investigated.

  11. Traitement par plasma thermique d'une liqueur caustique pour la destruction des cyanures

    NASA Astrophysics Data System (ADS)

    Fortin, Luc

    L'objectif principal de cette recherche est d'evaluer la possibilite de traiter le lixiviat de brasques usees produit par le procede LCL&L (Lixiviation a bas caustique et chaulage) par contact direct avec un jet de plasma thermique. L'utilisation d'un chalumeau au plasma permet d'eliminer les problemes de reaction avec les produits de combustion relies a l'utilisation de chalumeaux conventionnels (e.g. carbonatation du NaOH en Na2CO3). Le fait de se servir de ce type de chalumeau en mode submerge pour le traitement d'une solution liquide constitue l'originalite du projet. Les essais effectues dans le cadre de ce travail experimental sont realises a l'echelle banc d'essai dans un premier temps. Ils visent a determiner le taux de decomposition des cyanures contenus dans le lixiviat sous des conditions de plasma thermique en fonction de differents parametres et a faire la mise a l'echelle d'un reacteur pilote. La puissance electrique fournie au chalumeau, la temperature et la pression d'operation, le point d'addition d'eau, le volume de lixiviat traite et l'addition de peroxyde d'hydrogene (H2O2) comme co-reactif ont tous un impact sur le taux de destruction des cyanures trouve. Sous toutes les conditions etudiees, le reacteur plasma offre un taux de destruction plus rapide qu'un reacteur agite sous pression pour une meme concentration en cyanures. Ainsi, la comparaison de la constante cinetique obtenue pour le reacteur agite avec une constante similaire pour le reacteur plasma (pente du graphique -ln(C/C0) en fonction du temps) est de 0.04x10-3 s-1 vs 0.59x10-3 s-1 a 100°C et de 1.85x10-3 s-1' vs 3x10 -3 s-1s a 170°C. Ces resultats confirment que le plasma joue un role important sur la decomposition des cyanures et qu'il contribue a en augmenter le taux de destruction. Suite aux connaissances acquises sur le banc d'essai, un reacteur pilote est concu. Un chalumeau au plasma d'une puissance de 60 kW-150 kW et fonctionnant avec l'air comme gaz plasmagene y est

  12. Caracterisation de la cohesion de l'interface AMF/polymere dans une structure deformable adaptative

    NASA Astrophysics Data System (ADS)

    Fischer-Rousseau, Charles

    Les structures déformables adaptatives (SDA) sont appelées à jouer un rôle important en aéronautique entre autres. Les alliages à mémoire de forme (AMF) sont un des candidats les plus prometteurs. Beaucoup de travail reste toutefois à faire avant que ces structures rencontrent les exigences élevées reliées à leur intégration dans un contexte aéronautique. Des travaux de recherche ont montré que la résistance à la décohésion de l’interface AMF/polymère peut être un élément limitant dans la performance des SDA. Dans ce travail, l’effet sur la résistance à la décohésion de l’interface AMF/polymère de divers traitements de surface, géométries de fil et types de polymère est évalué. La géométrie du fil est modifiée par une combinaison spécifique de laminage à froid et de recuit postdéformation qui maintient les propriétés de mémoire de forme tout en permettant de réduire l’aire de la section transversale du fil. Le traitement thermomécanique le plus prometteur est proposé. Une nouvelle méthode d’évaluation de la résistance à la décohésion est développée. Plutôt que de tester les fils en arrachement et de mesurer la force maximale, les tests en contraction sont basés sur la capacité des fils d’AMF à se contracter s’ils ont été encastrés dans un état tiré et qu’ils sont chauffés par effet Joule. L’hypothèse qu’on pose est que ces tests sont une meilleure approximation des conditions rencontrées dans une SDA, où les fils se contractent plutôt qu’ils sont arrachés par une force externe à la structure. Bien qu’une décohésion partielle ait été observée pour tous les échantillons, l’aire de la surface où il y a décohésion tait plus grande pour les échantillons avec une pré-déformation plus grande. Le front de décohésion a semblé cesser de progresser après les cycles de chauffage initiaux lorsque la vitesse de chauffage était faible. Un modèle numérique simulant la

    PubMed Central

    2014-01-01

    The idea that human morality might be the product of evolution is not popular. The reason is partly that the moral principles that actually govern our day-to-day behavior have been idealized in a way that makes a natural origin seem impossible. This paper puts the case for a more down-to-earth assessment of human morality by arguing that the evolution of our sense of fairness can be traced to the practicalities of food-sharing. When animals share food, they can be seen as enjoying the fruits of an implicit bargain to ensure each other against hunger. The implications of this observation are explored using the tools of game theory. The arguments lead to a structure for fair bargains that closely resembles the structure proposed by John Rawls, the leading moral philosopher of the last century. PMID:25024181

  17. Fair trade international surrogacy.

    PubMed

    Humbyrd, Casey

    2009-12-01

    Since the development of assisted reproductive technologies, infertile individuals have crossed borders to obtain treatments unavailable or unaffordable in their own country. Recent media coverage has focused on the outsourcing of surrogacy to developing countries, where the cost for surrogacy is significantly less than the equivalent cost in a more developed country. This paper discusses the ethical arguments against international surrogacy. The major opposition viewpoints can be broadly divided into arguments about welfare, commodification and exploitation. It is argued that the only valid objection to international surrogacy is that surrogate mothers may be exploited by being given too little compensation. However, the possibility of exploitation is a weak argument for prohibition, as employment alternatives for potential surrogate mothers may be more exploitative or more harmful than surrogacy. It is concluded that international surrogacy must be regulated, and the proposed regulatory mechanism is termed Fair Trade Surrogacy. The guidelines of Fair Trade Surrogacy focus on minimizing potential harms to all parties and ensuring fair compensation for surrogate mothers. PMID:19508290

    Proton radiography was invented in the 1990's at Los Alamos National Laboratory (LANL) as a diagnostic to study dynamic material properties under extreme pressures, strain and strain rate. Since this time hundreds of dynamic proton radiography experiments have been performed at LANL and a facility has been commissioned at the Institute for Theoretical and Experimental Physics (ITEP) in Russia for similar applications in dynamic material studies. Recently an international effort has investigated a new proton radiography capability for the study of dynamic material properties at the Facility for Anti-proton and Ion Research (FAIR) located in Darmstadt, Germany. This new Proton microscope for FAIR(PRIOR) will provide radiographic imaging of dynamic systems with unprecedented spatial, temporal and density resolution, resulting in a window for understanding dynamic material properties at new length scales. It is also proposed to install the PRIOR system at the GSI Helmholtzzentrum fuer Schwerionenforschung before installation at FAIR for dynamic experiments with different drivers including high explosives, pulsed power and lasers. The design of the proton microscope and expected radiographic performance is presented.

    La maladie de Lyme est une zoonose qui se manifeste essentiellement par des signes cutanés, articulaires, neurologiques et cardiaques. Elle peut exceptionnellement mimer une dermatomyosite. Nous rapportons l'observation d'une patiente âgée de 37 ans qui a présenté des myalgies et un érythroedème de la face et en péri-orbitaire. Une dermatomyosite a été fortement suspectée devant une élévation des enzymes musculaires. Elle a été traitée par une corticothérapie à forte dose. L’évolution a été marquée par l'aggravation des myalgies et l'apparition d'un déficit musculaire. Elle a été alors hospitalisée dans notre service. Les enzymes musculaires étaient élevées. L’électromyogramme était sans anomalies. Le bilan immunologique était négatif. Une enquête infectieuse a été réalisée retrouvant une sérologie de Lyme positive.

    La maladie de Fanconi ou l'anémie de Fanconi (AF) est une maladie génétique rare à transmission autosomique récessive. Elle est marquée par une hétérogénéité phénotypique. Certains symptômes et notamment la triade classique faite d'une petite taille, d'un syndrome malformatif varié et parfois discret et d'une insuffisance médullaire d'apparition précoce, doivent faire évoquer le diagnostic. Nous rapportons le cas d'un enfant âgé de sept ans, suivi et traité pour une luxation congénitale des hanches, qui présentait une pancytopénie avec à l'examen clinique on note un faciès dysmorphique triangulaire, une duplication du pouce droit, une surélévation de l’épaule gauche et un retard staturo-pondéral.

  6. Teeth white and fair.

    Most dentists practicing today, in fact most dentists living today, accept porcelain, in one form or another, as a fundamental determinant of dental armamentarium. It must be remembered, however, that porcelain, in spite of some admonishments by the Chicken Littles, has not and is not about to fall like the sky. A great amount of purpose, intellect, and dedication proffered by porcelain's protagonists was the springboard that eventually led to near total acceptance of that product by dentists and the public they treated. Porcelain's introduction, however, was not accompanied by a professional unity that orchestrated its arrival with a blare of bugles and a ruffle of drums. Rather, the early proponents and opponents churned and swiped at each other for some decades. Teeth White and Fair recounts the origin, struggle, and growth of an early porcelain manufacturing company; the diversity of the men involved in the production of porcelain; the profession's dichotomy regarding the acceptance of porcelain; and the details of manufacture of that then embryonic dental product. Finally, the reader is given a peek at evolving cosmetic oriented materials that desire to garner ascension as valued players on the stages of cosmetic dental restorative materials. PMID:9709660

    ``Extrasolar Planet Transit", ``Lightcurve of a Variable Star", and ``Retrograde Motion of Mars" are some of the titles of high school students' projects entered in the Hawaii State Science Fair. TOPS (Toward Other Planetary Systems) teachers who participated in the University of Hawaii Institute for Astronomy summer outreach program under the direction of professor Karen J. Meech mentored their students. After attending the 3-week National Science Foundation Institute for several summers since 1999, these teachers in the summer of 2003 were trained to do observing plans to obtain images from telescopes, use image processing software MIRA for photometry, and produce light curves of variable stars and extrasolar planet transits. Others used the software ``Astrometrica" to do astrometry of Kuiper Belt Objects. Using Compaq laptop computers on long term loan, our teachers mentored students for astronomy projects during the 2003-2004 school year. These students made observing plans for images from the 31inch Lowell Telescope in Arizona and/or from the 2.2m University of Hawaii Telescope at Mauna Kea Observatory. Learning about filters, exposure time, magnitude, frequency of taking CCD images, and ephemeris required many iterations between students, teachers, and astronomers and graduate students who were assisting. Poor weather conditions and other frustrations exposed the students to the realities of research. However, they were rewarded with projects that impressed the judges and that will be described.

    Traditional fairing systems are designed to fully encapsulate and protect their payload from the harsh ascent environment including acoustic vibrations, aerodynamic forces and heating. The Orion fairing separation system performs this function and more by also sharing approximately half of the vehicle structural load during ascent. This load-share condition through launch and during jettison allows for a substantial increase in mass to orbit. A series of component-level development tests were completed to evaluate and characterize each component within Orion's unique fairing separation system. Two full-scale separation tests were performed to verify system-level functionality and provide verification data. This paper summarizes the fairing spring, Pyramidal Separation Mechanism and forward seal system component-level development tests, system-level separation tests, and lessons learned.

    FAIRNESS 2014 was the third edition in a series of workshops designed to bring together excellent international young scientists with research interests focused on physics at FAIR (Facility for Antiproton and Ion Research) and was held on September 22-27 2014 in Vietri sul Mare, Italy. The topics of the workshops cover a wide range of aspects in both theoretical developments and current experimental status, concentrated around the four scientific pillars of FAIR. FAIR is a new accelerator complex with brand new experimental facilities, that is currently being built next to the existing GSI Helmholtzzentrum for Schwerionenforschung close to Darmstadt, Germany. The spirit of the conference is to bring together young scientists, e.g. advanced PhD students and postdocs and young researchers without permanent position to present their work, to foster active informal discussions and build up of networks. Every participant in the meeting with the exception of the organizers gives an oral presentation, and all sessions are followed by an hour long discussion period. During the talks, questions are anonymously collected in a box to stimulate discussions. The broad physics program at FAIR is reflected in the wide range of topics covered by the workshop: • Physics of hot and dense nuclear matter, QCD phase transitions and critical point • Nuclear structure, astrophysics and reactions • Hadron Spectroscopy, Hadrons in matter and Hypernuclei • New developments in atomic and plasma physics • Special emphasis is put on the experiments CBM, HADES, PANDA, NUSTAR, APPA and related experiments For each of these different areas one invited speaker was selected to give a longer introductory presentation. The write-ups of the talks presented at FAIRNESS 2014 are the content of this issue of Journal of Physics: Conference Series and have been refereed according to the IOP standard for peer review. This issue constitutes therefore a collection of the forefront of research that

    L'hématocolpos est l'accumulation progressive du sang menstruel dans la cavité vaginale à la puberté. Il est souvent la conséquence d'une imperforation de l'hymen. Il se traduit sur le plan clinique par des douleurs pelviennes cycliques et une aménorrhée primaire. Plus rarement, il peut se révéler par une masse pelvienne. L’échographie est l'examen de choix pour le diagnostic de l'hématocolpos sur imperforation de l'hymen. L'imagerie par résonance magnétique (IRM) est l'examen d'imagerie de référence pour confirmer l'hématolcolpos et exclure d'autres malformations du canal de Muller ou des malformations urologiques associées. Nous rapportons un cas d'hématocolpos secondaire à une imperforation hyménéale diagnostiqué chez une jeune fille présentant une aménorrhée primaire et une masse pelvienne.

    The Facility for Antiproton and Ion Research, FAIR, is a new particle accelerator facility to be built at the GSI site in Germany. The research at FAIR will cover a wide range of topics in nuclear and hadron physics, high density plasma and atomic physics, and applications in condensed matter physics and biology. A 1.1 km circumference double ring of rapidly cycling 100 and 300 Tm synchrotrons, will be FAIR's central accelerator system. It will be used to produce, inter alia, high intensity secondary beams of antiprotons and short-lived radioactive nuclei. A subsequent suite of cooler and storage rings will deliver heavy ion and antiproton beams of unprecedented quality. Large experiments are presently being designed by the NUSTAR, PANDA, PAX, CBM, SPARC, FLAIR, HEDgeHOB and BIOMAT collaborations.

    2007-06-13

    Understanding the interplay of the nuclear interaction with polarized protons and the electromagnetic interaction with polarized electrons in polarized atoms is crucial to progress towards the PAX goal to eventually produce stored polarized antiproton beams at FAIR. Presently, there exist two competing theoretical scenarios: one with substantial spin filtering of (anti)protons by atomic electrons, and a second one suggesting a self-cancellation of the electron contribution to spin filtering. After a brief review of the PAX physics case for polarized antiprotons at FAIR, a detailed discussion of future investigations, including spin-filtering experiments at COSY-Juelich and at the AD of CERN is presented.

    valuent les effets des interventions liées aux médicaments sur le dépistage du CCR par RSOS sont limitées par leur moins bonne qualité et parce qu’elles ne se penchent pas sur la sensibilité et la spécificité. Par contre, les données probantes disponibles ne font pas valoir de bienfaits à cesser les AINS, les médicaments anticoagulants ou le fer durant la période du dépistage. Ces recommandations devraient être abandonnées de manière à maximiser l’observance du dépistage. Les résultats positifs d’une RSOS chez les patients qui prennent ces médicaments doivent faire l’objet d’une évaluation complète pour dépister un éventuel CCR. Jusqu’à ce que d’autres études précisent l’effet de l’acide ascorbique sur le dépistage par RSOS, il semble prudent de faire cesser ce médicament avant les tests.

  15. Nouveau procédé de synthèse du nitrure d'aluminium

    NASA Astrophysics Data System (ADS)

    Haussonne, J. M.; Lostec, J.; Bertot, J. P.; Lostec, L.; Sadou, S.

    1993-04-01

    Thermodynamic considerations show that, even at room temperature, pure aluminium can react with nitrogen to form the aluminium nitride AlN. However, pure aluminium does not exist: it is always surrounded by an alumina shell that protects the metal from further reactions. Furthermore, in the hypothesis where one has been able to make aluminium react with nitrogen, an aluminium nitride shell will protect as well the metal core from further oxidation. Prompted by the Lanxide process allowing to form Al/Al2O3 composites, we have mixed aluminium powders with lithium salts, and easily synthesized pure aluminium nitride by heating the mixed powders in nitrogen at temperatures ranging from 800 to 1200 °C. Starting from aluminium powders with a specific area ranging from 0.3 to 4 m^2/g, we have been able to produce aluminium nitride with specific are ranging from 1 to 20 m^2/g. Mixed with Y203-CaO and sintered at 1720 °C in N2, we obtained AIN ceramics owning 92% density and 160 W/m.K thermal conductivity. Les calculs thermodynamiques montrent que, même à température ambiante, l'aluminium pur peut réagir avec l'azote pour former le nitrure d'aluminium AlN. Cependant, la poudre d'aluminium pur n'existe pas : ses grains sont toujours entourés d'une couche d'alumine protectrice. De plus, dans l'hypothèse où l'on pourrait faire réagir de la poudre d'aluminium avec de l'azote, il se formerait de même une couche protectrice de nitrure d'aluminium qui empêcherait le centre des grains de réagir. S'inspirant du “procédé Lanxide” permettant de réaliser des composites Al/Al2O3, nous avons mélangé de la poudre d'aluminium avec des sels de lithium, et synthétisé du nitrure d'aluminium pur en portant ce mélange dans l'azote à une température pouvant être comprise entre 800 et 1 200 °C. Utilisant des poudres d'aluminium possédant une surface spécifique comprise entre 0,3 et 4 m^2/g, nous avons obtenu une poudre de nitrure d'aluminium avec une surface sp

  17. Children develop a veil of fairness.

    PubMed

    Shaw, Alex; Montinari, Natalia; Piovesan, Marco; Olson, Kristina R; Gino, Francesca; Norton, Michael I

    2014-02-01

    Previous research suggests that children develop an increasing concern with fairness over the course of development. Research with adults suggests that the concern with fairness has at least 2 distinct components: a desire to be fair and a desire to signal to others that they are fair. We explore whether children's developing concern with behaving fairly toward others may in part reflect a developing concern with appearing fair to others. In Experiments 1 and 2, most 6- to 8-year-old children behaved fairly toward others when an experimenter was aware of their choices; fewer children opted to behave fairly, however, when they could be unfair to others yet appear fair to the experimenter. In Experiment 3, we explored the development of this concern with appearing fair by using a wider age range (6- to 11-year-olds) and a different method. In this experiment, children chose how to assign a good or bad prize to themselves and another participant by either unilaterally deciding who would get each prize or using a fair procedure--flipping a coin in private. Older children were much more likely to flip the coin than younger children, yet were just as likely as younger children to assign themselves the good prize by reporting winning the coin flip more than chance would dictate. Overall, the results of these experiments suggest that as children grow older they become increasingly concerned with appearing fair to others, which may explain some of their increased tendency to behave fairly.

    Résumé Objectif Présenter aux cliniciens une mise à jour sur le diagnostic de la maladie cœliaque (MC), ainsi que des recommandations sur les indications de procéder au dépistage de la MC chez les patients présentant une faible densité minérale osseuse (DMO) ou des fractures de fragilité. Qualité des données Un groupe de travail multidisciplinaire a élaboré des questions cliniquement pertinentes relativement au diagnostic de la MC servant de fondement à une recherche documentaire dans les bases de données MEDLINE, EMBASE et CENTRAL (de janvier 2000 à janvier 2009) à l’aide des mots clés en anglais celiac disease, osteoporosis, osteopenia, low bone mass et fracture. Les ouvrages scientifiques existants comportent des études de niveaux I et II. Message principal La prévalence estimée de la MC asymptomatique est de 2 % à 3 % chez les personnes qui ont une faible DMO. Par ailleurs, un dépistage ciblé est recommandé pour les patients qui ont des T-scores de −1,0 ou moins à la colonne vertébrale ou aux hanches ou des antécédents de fractures de fragilité associées à des symptômes ou à des problèmes reliés à la MC, des antécédents familiaux de MC ou de bas niveaux de calcium urinaire, une insuffisance en vitamine D et des niveaux à la hausse d’hormones parathyroïdiennes en dépit d’un apport suffisant en calcium et en vitamine D. Le dépistage de la MC devrait se faire pendant que le sujet consomme un régime alimentaire contenant du gluten. On procède au dépistage initial par le dosage d’immunoglobuline (Ig) A antitransglutaminase en utilisant la transglutaminase tissulaire humaine recombinante ou une autre transglutaminase tissulaire, en association avec l’immunofluorescence des IgA anti-endomysium. Une biopsie du duodénum est nécessaire pour confirmer le diagnostic de la MC. Le typage des antigènes des leucocytes humains peut aider à confirmer ou à exclure le diagnostic de la MC dans les cas où la s

  19. Blocage de Coulomb dans une boite quantique laterale contenant un faible nombre d'electrons

    NASA Astrophysics Data System (ADS)

    Gould, Charles

    Dans ce travail on utilise une nouvelle geometrie pour augmenter le controle sur le nombre d'electrons contenus dans une boite quantique laterale, et ainsi atteindre un regime de petit nombre d'electrons. Ces echantillons permettent une etude du blocage de Coulomb quand les electrons sont injectes a partir d'un gaz electronique a deux dimensions (2DEG). Les mesures a faible champ magnetique demontrent la grande flexibilite des echantillons et montrent que l'on peut faire varier le nombre d'electrons dans une boite quantique a partir de plus de 40 electrons jusqu'a un seul electron, ce qui est assez courant dans les boites quantiques verticales, mais ce qui n'avait jamais ete reussi dans une boite quantique laterale. Nos resultats montrent egalement que dans les boites quantiques laterales il est possible de determiner le spin du niveau qui participe au transport a l'aide du phenomene de blocage de spin. De plus, dans certaines circonstances il est meme possible de determiner le spin total de la boite quantique, ce qui peut avoir des applications pratiques dans des domaines tels l'informatique quantique. Les mesures dans le regime de renversement de spin a un champ magnetique plus eleve montrent l'importance des correlations electrons---electrons dans ces boites quantiques, qui menent a des depolarisations et a des structures de spins qui ont un effet sur le transport. En particulier, ces correlations menent a l'existence de niveaux excites de basse energie qui causent une dependance anormale de l'amplitude des pics de blocage de Coulomb en fonction de la temperature. Nos experiences demontrent egalement la possibilite d'utiliser ces boites quantiques comme sondes pour etudier les proprietes du bord d'un 2DEG. Une voie de recherche a etre exploree.

  12. Fair weather terrestrial atmospheric electricity

    NASA Astrophysics Data System (ADS)

    Harrison, G.

    Atmospheric electricity is one of the oldest experimental topics in atmospheric science. The fair weather aspects, although having less dramatic effects than thunderstorm electrification, link the microscale behaviour of ion clusters to currents flowing on the global scale. This talk will include a survey of some past measurements and measurement methods, as atmospheric electrical data from a variety of sites and eras are now being used to understand changes in atmospheric composition. Potential Gradient data was the original source of information on the global atmospheric electrical circuit, and similar measurements can now be used to reconstruct past air pollution concentrations, and black carbon loading.

  13. Fairness and dynamic pricing: comments

    2010-07-15

    In ''The Ethics of Dynamic Pricing,'' Ahmad Faruqui lays out a case for improved efficiency in using dynamic prices for retail electricity tariffs and addresses various issues about the distributional effects of alternative pricing mechanisms. The principal contrast is between flat or nearly constant energy prices and time-varying prices that reflect more closely the marginal costs of energy and capacity. The related issues of fairness criteria, contracts, risk allocation, cost allocation, means testing, real-time pricing, and ethical policies of electricity market design also must be considered.

    Gaudreau, Louis

    Nous presentons dans cette these une etude detaillee du moment magnetique intrinseque de l'electron, i.e. le spin electronique, incluant la manipulation quantique coherente des etats de spin de trois electrons couples. A cette fin, nous utilisons des boites quantiques laterales pour confiner les electrons. Ces nano-structures, d'une grandeur autour de 1 pm, permettent de confiner un nombre precis d'electrons de facon controlee, allant jusqu'a zero electrons. Les developpements technologiques et d'ingeniosite durant la derniere decennie ont permis de coupler trois boites quantiques, ainsi l'interaction entre plusieurs electrons confines peut etre controlee comme par exemple le couplage quantique tunnel et l'interaction d'echange entre les spins de chacun d'entre eux. A l'aide de boites quantiques couplees, il est possible de realiser des experiences dans plusieurs domaines de la physique moderne : les etats up et down du spin des electrons confines peuvent etre utilisees comme etats quantiques binaires (qubits) dans le domaine de l'informatique quantique, la non-localite quantique peut etre testee en separant spatialement deux electrons enchevetres, il est possible de creer des 'courants de spin enchevetres' utiles en spintronique, et bien d'autres. La manipulation coherente des etats de spin du systeme a trois electrons se fait de facon purement electrique grace a des pulses a haute frequence qui permettent d'augmenter le couplage entre les electrons et de faire la mesure de l'etat resultant apres la manipulation. Nous utilisons l'interaction hyperfine entre les spins des electrons et ceux des noyaux du cristal dans lequel ils resident pour creer les rotations quantiques entre les etats, notamment les etats |Q +3/2> et (D+1/2>. Les resultats obtenus indiquent un temps de coherence de l'ordre de 10 ns. Ces experiences demontrent un niveau de controle sans precedant de boites quantiques triples et pavent la voie vers des nano-structures plus sophistiquees dans

  16. Calculating fairness. [Estimating fair return on equity for public utilities

    SciTech Connect

    Makholm, J.D.; Sander, D.O. )

    1993-11-15

    Despite the recent restructuring, unbundling, competition, and incentive regulation that has complicated the utility business, estimating the fair rate of return on equity (ROE) remains an important part of public utility base rate cases. For the past two decades, the two most popular methods that regulatory commissions have used for estimating the cost of equity capital for regulated utilities have been the dividend discount method (known as the Discounted Cash Flow model of DCF) and the Capital Asset Pricing Model (or CAPM). Both models use common stock price behavior to draw inferences about the cost of equity. The DCF combines a stock's dividend yield and its predicted dividend growth rate. The CAPM relates changes in a stock's price to changes in the overall market for security prices. These methods have come into question, however, as utilities have increasingly diversified into unregulated activities. When a utility's regulated activities account for 95 to 99 percent of its revenues, there is little practical need to question that its company-specific cost-of-equity capital is overwhelmingly dominated by its regulated activities. But as this percentage continues to decrease, a company's specific cost of equity, as calculated by the DCF or CAPM, is influenced to a larger degree by its unregulated subsidiaries. Two general remedies are available to resolve the problem of setting the fair ROE when the company has substantial holdings in unregulated subsidiaries. One is to abandon (either partially or fully) the practice of using company-specific market information and use a proxy group of comparable utilities instead. The other is to continue using company-specific data, but to adjust the resulting estimates to account for the utility's diversification activity.

  17. Nuclear isoscaling and fair sampling

    NASA Astrophysics Data System (ADS)

    Lopez, Jorge

    2008-10-01

    The isoscaling phenomenon was first observed in nuclear multifragmentation experiments and has become a hot topic as it could provide a probe of the nuclear equation of state to understand nuclear matter at extreme condition of isospin such as in neutron stars. The present work studies isoscaling using 1) classical molecular dynamics simulations, 2) percolation and 3) probabilistic arguments, and determines that isoscaling is a general phenomenon that can exist independent of the nuclear reaction, and it is expected to occur in disassemblying systems with no more than fair sampling.

    2006-03-20

    A new accelerator Facility for Research with Antiproton and Ion Beams (FAIR) has been proposed by GSI. This contribution will give a short overview of the present status of the accelerator complex design with particular emphasis on the installations which employ cooling devices. Stochastic and electron cooling are foreseen in the different storage rings over a large energy range. Stochastic cooling will be applied as first cooling stage to secondary beams of rare isotopes which are produced by projectile fragmentation of heavy ions and to antiprotons which are produced from a high intensity proton beam. In the storage rings which are predominantly used for experiments the highest beam quality of the stored beam will be achieved by electron cooling.

    Science literacy is imperative for well informed civic and personal decision making, yet only a quarter of American adults are proficient enough in science to understand science stories reported in the popular press. Hands-on research increases confidence in and understanding of science. When guiding students in designing and conducting science fair projects, mentors can foster science literacy by helping students focus on three goals: (1) articulating hypotheses or questions, (2) designing feasible projects, and (3) learning to make and interpret graphs. These objectives introduce students to the methodological nature of scientific research and give them the tools to interpret scientific facts and data in order to make informed decisions for themselves and society.

  20. The PANDA experiment at FAIR

    2013-12-01

    The PANDA (antiProton ANnihilation at DArmstadt) experiment is one of the major projects in preparation at the upcoming FAIR facility in Darmstadt, Germany. It will study interactions between antiprotons and protons or nuclei in the momentum range from 1.5 GeV/c to 15 GeV/c. The PANDA scientific program will address a wide range of topics, all aiming at improving our understanding of the strong interaction and hadron structure. The PANDA detector is a general-purpose spectrometer that will collect high quality and high statistics data in the fields of meson spectroscopy, baryon-antibaryon production, baryon spectroscopy, hypernuclear physics, hadron properties in the nuclear medium, and nucleon structure. This paper reviews some of the main physics topics of the experiment, together with a presentation of the detector.

    A sense of fairness plays a critical role in supporting human cooperation. Adult norms of fair resource sharing vary widely across societies, suggesting that culture shapes the acquisition of fairness behaviour during childhood. Here we examine how fairness behaviour develops in children from seven diverse societies, testing children from 4 to 15 years of age (n = 866 pairs) in a standardized resource decision task. We measured two key aspects of fairness decisions: disadvantageous inequity aversion (peer receives more than self) and advantageous inequity aversion (self receives more than a peer). We show that disadvantageous inequity aversion emerged across all populations by middle childhood. By contrast, advantageous inequity aversion was more variable, emerging in three populations and only later in development. We discuss these findings in relation to questions about the universality and cultural specificity of human fairness. PMID:26580018

    Fairness considerations fundamentally affect human behavior, but our understanding of the nature and development of people's fairness preferences is limited. The dictator game has been the standard experimental design for studying fairness preferences, but it only captures a situation where there is broad agreement that fairness requires equality. In real life, people often disagree on what is fair because they disagree on whether individual achievements, luck, and efficiency considerations of what maximizes total benefits can justify inequalities. We modified the dictator game to capture these features and studied how inequality acceptance develops in adolescence. We found that as children enter adolescence, they increasingly view inequalities reflecting differences in individual achievements, but not luck, as fair, whereas efficiency considerations mainly play a role in late adolescence.

  11. Elementary school teachers and successful science fairs

    NASA Astrophysics Data System (ADS)

    Cook, Helen Mounce

    The purpose of this research was to examine the knowledge, skills and attitudes of elementary school teachers who have led their students to successful experiences in science fairs. Six research questions guided the study: (1) What knowledge, skills and attitudes do the five selected elementary school teachers draw upon to enable their students to have a successful science fair experience? (2) How do the five selected elementary school teachers enable their students to have a successful science fair experience? (3) Why are the five selected elementary school teachers capable of enabling their students to have a successful science fair experience? (4) How do the knowledge, skills and attitudes of the five selected elementary school teachers compare to the knowledge, skills and attitudes that the National Science Education Standards (National Research Council, 1996) recommend for science teachers? (5) What are the commonalities in the knowledge, skills and attitudes among the five selected elementary school teachers who enable their students to have a successful science fair experience? (6) What are the differences in the knowledge, skills and attitudes among the five selected elementary school teachers who enable their students to have a successful science fair experience? A qualitative multiple-case research design was used to focus on five elementary school teachers who have a history of leading their students to successful experiences in science fairs. Data sources included classroom observations, formal and informal interviews, focus groups, science fair visitations and perusal of documents related to the teachers' science fair preparation of their students. In addition, questionnaires were given to the teachers and their students assessing their views about science and science fairs. A cross-case analysis revealed that the teachers had become knowledgeable about science fairs and science by non-traditional means including attending staff development workshops

    2015-11-01

    The FAIR facility, under construction at the GSI site in Darmstadt, will be addressing a wealth of outstanding questions within the realm of subatomic, atomic, plasma, bio-physics and applications through a combination of novel accelerators, storage rings and innovative experimental set-ups. One of the key installations is the fragment separator Super-FRS that will be able to deliver an unprecedented range of radioactive ion beams in the energy range of 0-1.5 GeV u-1. These beams will be distributed to three branches, each with its unique domain with respect to beam energies and properties. The high-energy branch will permit reactions with radioactive beams at relativistic energies, whereas the low-energy branch will supply decelerated beams for high-resolution spectroscopy, traps and laser spectroscopy. Finally, the ring branch will uniquely permit stored and cooled exotic beams for a range of methods only possible in a storage ring. Thus, by developing experimental set-ups tailored for these beams, there are several complementary possibilities to gain information on key nuclei and reaction, to further our understanding on contemporary questions within nuclear structure and nuclear astrophysics. This ambitious programme is to be exploited within the nuclear structure, astrophysics and reactions collaboration.

    2004-11-01

    Extrasolar Planet Transit and The Light Curve of a Variable Star are some titles of high school student projects entered in the Hawaii State Science Fair. These students were mentored by teachers who participated in the UH Institute for Astronomy Toward Other Planetary Systems summer program under the direction of professor Karen J. Meech. After attending several 3-week TOPS NSF workshops from 1999, these teachers in 2003 were trained to do observing plans to obtain telescope images, use image processing software MIRA for photometry, and produce light curves of variable stars and extrasolar planet transits. Others used the software Astrometrica to do astrometry of Kuiper Belt Objects. Using Compaq laptop computers on long term loan, our teachers mentored their students for astronomy projects during the 2003-2004 school year with the assistance of IfA astronomers and graduate students. Observing plans for images from the 31 inch Lowell Telescope in Arizona and the 2.2 meter UH telescope at Mauna Kea Observatory were followed. Students had to learn about variables such as exposure time, magnitude, frequency requirements, and ephemeris. The many iterations were time consuming and demanded patience and perseverance. Poor weather conditions exposed the students to the realities of astronomy research, so they experienced the highs of successful projects. Future projects will be related to the UH NAI team research using the 2.0 meter Faulkes Telescope located on Haleakala on island of Maui. The TOPS program is funded by National Science Foundation.

  14. Landing gear noise control using perforated fairings

    NASA Astrophysics Data System (ADS)

    Boorsma, K.; Zhang, X.; Molin, N.

    2010-05-01

    Landing gears of commercial aircraft make an important contribution to total aircraft noise in the approach configuration. Using fairings to shield components from high speed impingement reduces noise. Furthermore, perforating these fairings has been confirmed by flight tests to further enable noise reduction. Following an earlier fundamental study of the application of perforated fairings, a study has been performed to investigate and optimize the benefits of bleeding air through landing gear fairings. By means of wind tunnel tests, an aerodynamic and acoustic survey has been performed on a simplified generic main landing gear to explore the influence of (perforated) fairings on the lower part of the gear. The results show that for this specific case, the application of impermeable fairings reduces noise in the mid- and high frequency range by shielding sharp edged components from high velocity impingement. However, below 1 kHz the noise is shown to increase significantly. Application of the perforations is shown to diminish this low frequency increase whilst maintaining the reduction in the mid- and high frequency range. The aerodynamic and acoustic measurements point in the direction of the separated flow of the fairings interacting with the downstream gear components responsible for the low frequency noise increase. Bleeding of the air through the fairings reduces the large scale turbulence in the proximity of these components and hence diminishes the low frequency noise increase.

  1. Helicopter hub fairing and pylon interference drag

    NASA Technical Reports Server (NTRS)

    Graham, D. R.; Sung, D. Y.; Young, L. A.; Louie, A. W.; Stroub, R. H.

    1989-01-01

    A wind tunnel test was conducted to study the aerodynamics of helicopter hub and pylon fairings. The test was conducted in the 7-by 10 Foot Subsonic Wind Tunnel (Number 2) at Ames Research Center using a 1/5-scale XH-59A fuselage model. The primary focus of the test was on the rotor hub fairing and pylon mutual interference drag. Parametric studies of pylon and hub fairing geometry were also conducted. This report presents the major findings of the test as well as tabulated force and moment data, flow visualization photographs, and graphical presentations of the drag data. The test results indicate that substantial drag reduction can be attained through the use of a cambered hub fairing with circular arc upper surface and flat lower surface. Furthermore, a considerable portion of the overall drag reduction is attributed to the reduction in the hub-on-pylon interference drag. It is also observed that the lower surface curvature of the fairing has a strong influence on the hub fairing and on pylon interference drag. However, the drag reduction benefit that was obtained by using the cambered hub fairing with a flat lower surface was adversely affected by the clearance between the hub fairing and the pylon.

    Summary Aussi loin que l’on remonte dans la littérature, on retrouve des récits relatant des accidents consécutifs à la fulguration chez l’homme. La foudre était alors associée à la colère des dieux ou à la notion de châtiment. La fulguration correspond à un transfert d’énergie entre un cumulonimbus de charge négative et un objet de charge positive se trouvant au niveau du sol. Les lésions déterminées sont à la fois thermiques et électrothermiques. Bien que l’arrêt cardiorespiratoire soit une cause bien documentée de décès, la plupart des cas rapportés dans la littérature décrivent un éventail très disparate des séquelles qui surviennent suite à cet accident. Les Auteurs rapportent le cas d’un patient atteint par la foudre en insistant particulièrement sur les complications neurologiques qui sont survenues en cours d’évolution. Se basant sur cette observation et sur une revue de la littérature, les Auteurs soulignent que le pronostic des patients atteints par la foudre est plus favorable que généralement rapporté.

    L'IDM per gravidique est une complication grave qui entraine une morbidité et une mortalité maternelle élevée. Bien que l'athérosclérose soit la cause d'IDM la plus fréquente dans la population générale, elle n'est observée que chez un tiers des femmes enceintes. Chez ces dernières, la cause la plus fréquente d'IDM était la dissection coronaire. Nous rapportons l'observation clinique d'une jeune femme de 24 ans, sans facteur de risque cardiovasculaire, qui a présenté un IDM antérieur étendu 15 jours après un accouchement, en rapport avec une dissection de la partie proximale de l'artère inter ventriculaire antérieure. Le traitement de cette pathologie n'est pas consensuel, et peut faire appel, selon la présentation clinique et angiographique, au traitement médical, à une revascularisation par pontage aorto-coronaire avec une résection de l'hématome de la paroi artérielle, ou à l'angioplastie transluminale. Le pronostic semble assez favorable quoique controversé. PMID:26161172

    La synovite villonodulaire (SVN) est une prolifération pseudotumorale bénigne rare de la synoviale articulaire, d’étiologie inconnue. Elle peut aussi se développer au sein des bourses séreuses, des gaines tendineuses. Généralement, elle atteint les grosses articulations notamment le genou et la hanche. La localisation de la cheville est rare, avec seulement quelques cas publiés dans la littérature. Nous rapportons un cas de patiente de 52 ans présentant une SVN de la cheville droite. Elle a bénéficié d'une synovectomie subtotale. A deux ans de recul, il n'y avait pas de récidive clinique. PMID:27231502

    Résumé Objectif Effectuer une étude de la portée des données empiriques, entre 1980 et 2009, concernant les soins primaires aux adultes victimes d’une lésion médullaire (LME). Sources des données Une recension dans des revues révisées par des pairs de1980 à 2009 à l’aide de CINAHL, PubMed-MEDLINE, EMBASE, PsycINFO, Social Sciences Abstracts et Social Work Abstracts. Sélection des études La recherche électronique au moyen de mots-clés a permis de cerner 42 articles sur les soins primaires et les LME. Des critères d’inclusion ont servi à réduire la liste à un ensemble de 21 articles publiés en anglais qui portaient sur un échantillon de plus de 3 et présentaient une analyse empirique. Synthèse Environ 90 % des personnes atteintes d’une LME ont identifié leur médecin de famille comme étant leur docteur habituel; 63 % avaient un spécialiste des LME. Les personnes vivant à long terme avec une LME développent des rubriques complexes pour naviguer dans leurs systèmes de soins de santé personnels. Les données scientifiques ne sont pas unanimes quant à l’efficacité des programmes d’intervention directe pour le maintien de la santé et la prévention des complications à la suite d’une LME. Les données appuient cependant le suivi périodique par une équipe spécialisée et un bilan de santé annuel complet. La recherche fait valoir un fort degré d’uniformité dans l’identification des problèmes les plus courants soulevés par les personnes atteintes d’une LME en soins primaires, dont la plupart concernent l’incapacité, plus précisément les complications secondaires, comme la dysfonction intestinale ou vésicale et la douleur. Il existe aussi de bonnes données probantes à l’effet que de nombreux problèmes de santé généraux exigent de l’attention dans une telle population, comme les problèmes de la densité osseuse, la dépression et les questions entourant la santé sexuelle et la reproduction.

  1. Fair share on high performance computing systems : what does fair really mean?

    SciTech Connect

    Clearwater, Scott Harvey; Kleban, Stephen David

    2003-03-01

    We report on a performance evaluation of a Fair Share system at the ASCI Blue Mountain supercomputer cluster. We study the impacts of share allocation under Fair Share on wait times and expansion factor. We also measure the Service Ratio, a typical figure of merit for Fair Share systems, with respect to a number of job parameters. We conclude that Fair Share does little to alter important performance metrics such as expansion factor. This leads to the question of what Fair Share means on cluster machines. The essential difference between Fair Share on a uni-processor and a cluster is that the workload on a cluster is not fungible in space or time. We find that cluster machines must be highly utilized and support checkpointing in order for Fair Share to function more closely to the spirit in which it was originally developed.

  2. Organization and evaluation of health fairs.

    PubMed

    Germer, P; Price, J H

    1981-02-01

    In summary, the success of a health fair as a source of health education and promoter of healthful behaviors depends to a great extent upon the organizational expertise of the sponsor and cooperating forces. However, even more essential is the stimulation of health fair visitors' interest and participation, the provision of information and health status feedback and the reinforcement of positive health values. The health fair which best achieves these objectives will have a greater likelihood of also attaining its original preventive health goals and objectives. Although evaluation articles tend to stress the positive findings, this review does not imply that every health fair is a success or that every successful health fair is without criticism. Long waiting lines, unexpected equipment malfunctions, inadequate hours for visiting, understaffed activities, limited floor space and/or visual distractions and noise disturbances may still occur despite the most thorough organizational efforts. This review has attempted to synthesize from the existing sources on health fairs those essential organizational and evaluative factors necessary for a health fair to maximize its potential health education impact.

    Les complications pariétales post opératoire peuvent être exceptionnellement majeures et graves menaçant le pronostic vital. La fasciite nécrosante est une infection rare de la peau et des tissus sous-cutanés profonds, se propageant le long des fascias et du tissu adipeux. Elle est surtout causée par le streptocoque du groupe A Streptococcus pyogènes mais également par d'autres bactéries telles que Vibrio vulnificus, clostridium perfringens ou Bacteroides fragilis. La fasciite nécrosante est une véritable urgence médicochirurgicale. Nous rapportons dans ce travail une observation très rare d'une gangrène pariétale abdominale survenant chez une patiente de 75 ans au cinquième jour post-opératoire d'un kyste de l'ovaire. L’évolution était marquée par l'installation d'un état de choc septique réfractaire rapidement fatal à J3 de la prise en charge. PMID:27279950

  5. Young Children's Development of Fairness Preference.

    Li, Jing; Wang, Wen; Yu, Jing; Zhu, Liqi

    2016-01-01

    Fairness is one of the most important foundations of morality and may have played a key role in the evolution of cooperation in humans beings. As an important type of fairness concern, inequity aversion is the preference for fairness and the resistance to inequitable outcomes. To examine the early development of fairness preference in young children, sixty 2- and 3-year-old children were recruited to examine young children's preferences for fairness using a forced choice paradigm. We tested how toddlers acted when they took charge of distributing resources (two candies) to themselves and others and when they were the recipients of both other-advantageous distribution and self-advantageous distribution. Different alternative options were paired with the same fair option in the two conditions. In the other-advantageous condition, children had fewer resources in the alternative options than others, whereas their resources in the alternative options were greater than others' in the self-advantageous condition. The results showed that more children displayed fairness preferences when they distributed resources between two friends than when they distributed resources between a friend and themselves. In both scenarios, 3-year-old children were more likely to demonstrate fairness preference than 2-year-old children. The findings suggest that inequity aversion develops in young children and increases with age over the course of early childhood. When they were recipients, there was a trend in young children's preference for fairness in the other-advantageous condition compared with the self-advantageous condition. This suggests that children might tend to be more likely to display inequity aversion when they are in a disadvantageous position. PMID:27625616

  6. Teaching Fair Use with Astronomy Imagery

    Wilson, Teresa

    2016-01-01

    Plagiarism among students is most common because of a misunderstanding of copyright and fair use. Images and text are frequently used without proper credit to the original author, and works are frequently acknowledged improperly. For example, space imagery is often used in posters, presentations, on the web, on Facebook, and even in the classrooms, but often are not properly cited. A lesson plan on fair use is presented, outlining what constitutes fair use and how to properly acknowledge the work done by artists and authors everywhere, with examples drawn from the Astronomy Picture of the Day (APOD).

    Fairings are nearly-neutrally buoyant devices, which are fitted along the axis of long circular risers to suppress vortex induced vibrations (VIV) and possibly reduce the drag force. Here we study numerically how VIV can be practically eliminated by using free-to-rotate fairings. Since the mass ratio and rotational inertia are both low for the fairings, direct numerical simulations based on standard flow-structure interaction algorithms fail because of the so-called added mass effect. To resolve this problem we introduce fictitious methods and successfully stabilize the simulations. In particular, we investigate the effect of rotational friction Cf on the stabilization effect of the fairings. We found that there exists a critical value for the rotational friction, and when Cf is close to this value, large oscillations and unsymmetrical trajectories can be observed for the riser but for smaller Cf values VIV are suppressed substantially.

    The presence of apparently irrational fair play in the ultimatum game remains a focal point for studies in the evolution of social behaviour. We investigate the role of negative assortment in the evolution of fair play in the ultimatum game. Spite-social behaviour that inflicts harm with no direct benefit to the actor-can evolve when it is disproportionally directed at individuals playing different strategies. The introduction of negative assortment alters the dynamics in a way that increases the chance fairness evolves, but at a cost: spite also evolves. Fairness is usually linked to cooperation and prosocial behaviour, but this study shows that it may have evolutionary links to harmful antisocial behaviour. PMID:24523265

    Le schwannome est une tumeur le plus souvent bénigne, d'origine nerveuse se développant à partir des cellules de la gaine de Schwann. C'est une tumeur très rare tant par sa fréquence que par sa localisation rétrovésicale. L'examen anatomopathologique et immunohistochimique confirme le type histologique ainsi que le caractère bénin ou malin du schwannome. En raison des récidives, et du risque de transformation maligne, l'exérèse doit être complète. Nous rapportons le cas d'un patient âgé de 39 ans, admis pour une douleur pelvienne chronique à type de pesanteur, des signes irritatifs du bas appareil urinaire, et des troubles de transit. L'imagerie (échographie, TDM, IRM) a révélé la présence d'une masse pelvienne rétrovésicale, à paroi fine, latéralisée à gauche, mesurant 68x70x70 mm, exerçant un effet de masse sur la vessie et le sigmoïde. L'intervention chirurgicale menée par une laparotomie médiane a permis l'exérèse d'une masse retrovésicale bien encapsulée. L'examen anatomopathologique et immunohistochimique ont conclu à un schwannome bénin. La récidive et la transformation maligne bien que rare après chirurgie impose une surveillance post opératoire clinique et tomodensitométrique annuelle. PMID:27217902

    In a sample of 114 employees from various industries, organizations, and positions, the likelihood of organizational citizenship behaviors (OCB) increased when employee perceptions of fair treatment by supervisors became more positive. Perceptions of fair rewards and fair formal procedures were not predictors of OCB intentions. After the authors controlled for established patterns of OCB and demographic characteristics, interactional justice perceptions were significantly related to the intention of performing specific organizationally beneficial activities.

    Ce cas clinique rapporte un cas de tuberculose hépatique de présentation échographique exceptionnelle. Nous avons réalisé l’échographie abdominale d'un adolescent de 12 ans, immuno-compétent, sans notion de contage tuberculeux, se plaignant de douleur abdominale chronique évoluant depuis 8 mois associée à des signes frustres d‘imprégnation tuberculeuse. L'examen échographique a été réalisé à l'aide d'un appareil écho-doppler de marque Logic 400 de la firme General Electric. L’échographie abdominale a mis en évidence, une hépatomégalie comportant de multiples micro-abcès hypoéchogènes homogènes, mesurant entre 3 et 4 mm de diamètre et disséminés dans tout le parenchyme hépatique donnant l'aspect de miliaire. Une ascite de moyenne abondance localisée dans le pelvis a été objectivée. Il n'y avait pas d'adénopathies profondes ni de nodules péritonéaux. La ponction biopsie hépatique sous guidage échographique a permis de faire le diagnostic de tuberculose hépatique à l'histologie et à la bactériologie. Le patient a été mis sous traitement spécifique avec une surveillance échographique mensuelle. La disparition des micro-abcès et le tarissement de l'ascite ont été obtenus au bout du 4ème mois du traitement. Celle de l'hépatomégalie est survenue un mois plus tard. L’échographie joue un rôle très important dans la détection précoce de la tuberculose hépatique, son diagnostic précis et la surveillance du traitement. Lors de sa réalisation dans un contexte de douleur abdominale chronique chez l'enfant, l’échographiste devrait évoquer le diagnostic de tuberculose hépatique devant une hépatomégalie multi-micro-abcédée, même chez l'enfant immuno-compétent.

    The proposed project FAIR (Facility for Anti-proton and Ion Research) is an international accelerator facility of the next generation. It builds on top of the experience and technological developments already made at the existing GSI facility, and incorporate new technological concepts. The four scientific pillars of FAIR are NUSTAR (nuclear structure and astrophysics), PANDA (QCD studies with cooled beams of anti-protons), CBM (physics of hadronic matter at highest baryon densities), and APPA (atomic physics, plasma physics, and applications). The FairRoot framework used by all of the big FAIR experiments as a base for their own specific developments, provides basic functionality like IO, geometry handling etc. The challenge is to support all the different experiments with their heterogeneous requirements. Due to the limited manpower, one of the first design decisions was to (re)use as much as possible already available and tested software and to focus on the development of the framework. Beside the framework itself, the FairRoot core team also provides some software development tools. We will describe the complete set of tools in this article. The Makefiles for all projects are generated using CMake. For software testing and the corresponding quality assurance, we use CTest to generate the results and CDash as web front end. The tools are completed by subversion as source code repository and trac as tool for the complete source code management. This set of tools allows us to offer the full functionality we have for FairRoot also to the experiments based on FairRoot.

  5. Modeling for fairness: A Rawlsian approach.

    PubMed

    Diekmann, Sven; Zwart, Sjoerd D

    2014-06-01

    In this paper we introduce the overlapping design consensus for the construction of models in design and the related value judgments. The overlapping design consensus is inspired by Rawls' overlapping consensus. The overlapping design consensus is a well-informed, mutual agreement among all stakeholders based on fairness. Fairness is respected if all stakeholders' interests are given due and equal attention. For reaching such fair agreement, we apply Rawls' original position and reflective equilibrium to modeling. We argue that by striving for the original position, stakeholders expel invalid arguments, hierarchies, unwarranted beliefs, and bargaining effects from influencing the consensus. The reflective equilibrium requires that stakeholders' beliefs cohere with the final agreement and its justification. Therefore, the overlapping design consensus is not only an agreement to decisions, as most other stakeholder approaches, it is also an agreement to their justification and that this justification is consistent with each stakeholders' beliefs. For supporting fairness, we argue that fairness qualifies as a maxim in modeling. We furthermore distinguish values embedded in a model from values that are implied by its context of application. Finally, we conclude that for reaching an overlapping design consensus communication about properties of and values related to a model is required. PMID:25051870

  6. Partner choice creates fairness in humans.

    Debove, Stéphane; André, Jean-Baptiste; Baumard, Nicolas

    2015-06-01

    Many studies demonstrate that partner choice has played an important role in the evolution of human cooperation, but little work has tested its impact on the evolution of human fairness. In experiments involving divisions of money, people become either over-generous or over-selfish when they are in competition to be chosen as cooperative partners. Hence, it is difficult to see how partner choice could result in the evolution of fair, equal divisions. Here, we show that this puzzle can be solved if we consider the outside options on which partner choice operates. We conduct a behavioural experiment, run agent-based simulations and analyse a game-theoretic model to understand how outside options affect partner choice and fairness. All support the conclusion that partner choice leads to fairness only when individuals have equal outside options. We discuss how this condition has been met in our evolutionary history, and the implications of these findings for our understanding of other aspects of fairness less specific than preferences for equal divisions of resources.

    In 2005, Swiss citizens endorsed a moratorium on gene technology, resulting in the prohibition of the commercial cultivation of genetically modified crops and the growth of genetically modified animals until 2013. However, scientific research was not affected by this moratorium, and in 2008, GMO field experiments were conducted that allowed us to examine the factors that influence their acceptance by the public. In this study, trust and confidence items were analyzed using principal component analysis. The analysis revealed the following three factors: "economy/health and environment" (value similarity based trust), "trust and honesty of industry and scientists" (value similarity based trust), and "competence" (confidence). The results of a regression analysis showed that all the three factors significantly influenced the acceptance of GM field experiments. Furthermore, risk communication scholars have suggested that fairness also plays an important role in the acceptance of environmental hazards. We, therefore, included measures for outcome fairness and procedural fairness in our model. However, the impact of fairness may be moderated by moral conviction. That is, fairness may be significant for people for whom GMO is not an important issue, but not for people for whom GMO is an important issue. The regression analysis showed that, in addition to the trust and confidence factors, moral conviction, outcome fairness, and procedural fairness were significant predictors. The results suggest that the influence of procedural fairness is even stronger for persons having high moral convictions compared with persons having low moral convictions. PMID:22150405

  10. Getting a Fair Share: Attitudes and Perceptions of Biobank Stakeholders Concerning the Fairness of Sample Sharing.

    PubMed

    Colledge, Flora; Elger, Bernice

    2015-07-01

    Biobanks are essential tools for furthering a broad range of medical research areas. However, despite the plethora of national and international laws and guidelines which apply to them, the access and sharing policies of biobanks are only sparsely addressed by regulatory bodies. The 'give and take' process of biosample sharing is largely left up to biobank stakeholders themselves to oversee; it is therefore both in stakeholders' power, and in their interest, to ensure that sample accessibility is fair. This is an important step in motivating researchers to collaborate and pool samples, and is crucial to fostering trust in the absence of universally accepted standard practices. To date, little attention has been paid to how fairness considerations affect scientific material sharing, and no empirical research has been carried out to determine the role that fairness plays in collaborative studies. In order to begin to gain understanding in this area, we interviewed 36 biobank stakeholders currently working in Switzerland, focusing on their perceptions of current and optimal fair sharing practices. Our findings reveal that fairness is an important feature of exchange situations for these stakeholders, and that they have well-formed notions about the practical elements of fair sample access, although ideas about the concept of fairness itself are vague. In order to support efforts to network biobanks, attention should be paid to this issue to reassure all involved that they are getting a fair share in their cooperative efforts. PMID:25425240

    We propose a synthesis method to design a 90° bent fair circular waveguide TE01 mode transition based on the non-uniform rational B-spline technique. The transition by this method has advantages of small geometry, high transmission with wide band and high profile fairness. An example of design of such a transition is presented. The simulation shows that the transition exhibits a transmission as high as 99.3% at the central frequency 35 GHz and has a bandwidth of 16.7% when keeping the transmission over 95%. Furthermore, the profile is extremely fair, which meets the requirements to decrease the geometry errors between actual device and its design, to reduce the machining difficulty in the machining process. The hot test data indicate that good transmission of the TE01 mode is obtained. PMID:25638106

  5. Fair and optimistic quantum contract signing

    SciTech Connect

    Paunkovic, N.; Mateus, P.; Bouda, J.

    2011-12-15

    We present a fair and optimistic quantum-contract-signing protocol between two clients that requires no communication with the third trusted party during the exchange phase. We discuss its fairness and show that it is possible to design such a protocol for which the probability of a dishonest client to cheat becomes negligible and scales as N{sup -1/2}, where N is the number of messages exchanged between the clients. Our protocol is not based on the exchange of signed messages: Its fairness is based on the laws of quantum mechanics. Thus, it is abuse free, and the clients do not have to generate new keys for each message during the exchange phase. We discuss a real-life scenario when measurement errors and qubit-state corruption due to noisy channels and imperfect quantum memories occur and argue that for a real, good-enough measurement apparatus, transmission channels, and quantum memories, our protocol would still be fair. Apart from stable quantum memories, the other segments of our protocol could be implemented by today's technology, as they require in essence the same type of apparatus as the one needed for the Bennett-Brassard 1984 (BB84) cryptographic protocol. Finally, we briefly discuss two alternative versions of the protocol, one that uses only two states [based on the Bennett 1992 (B92) protocol] and the other that uses entangled pairs, and show that it is possible to generalize our protocol to an arbitrary number of clients.

  6. Fair process: managing in the knowledge economy.

    PubMed

    Kim, W C; Mauborgne, R

    1997-01-01

    Unlike the traditional factors of production--land, labor, and capital--knowledge is a resource that can't be forced out of people. But creating and sharing knowledge is essential to fostering innovation, the key challenge of the knowledge-based economy. To create a climate in which employees volunteer their creativity and expertise, managers need to look beyond the traditional tools at their disposal. They need to build trust. The authors have studied the links between trust, idea sharing, and corporate performance for more than a decade. They have explored the question of why managers of local subsidiaries so often fail to share information with executives at headquarters. They have studied the dynamics of idea sharing in product development teams, joint ventures, supplier partnerships, and corporate transformations. They offer an explanation for why people resist change even when it would benefit them directly. In every case, the decisive factor was what the authors call fair process--fairness in the way a company makes and executes decisions. The elements of fair process are simple: Engage people's input in decisions that directly affect them. Explain why decisions are made the way they are. Make clear what will be expected of employees after the changes are made. Fair process may sound like a soft issue, but it is crucial to building trust and unlocking ideas. Without it, people are apt to withhold their full cooperation and their creativity. The results are costly: ideas that never see daylight and initiatives that are never seized. PMID:10168337
