    The QUench Experiment on Long Length (QUELL) in the SULTAN Facility is planned to investigate the quench propagation and detection of a conductor with ITER relevant geometry and scaled performance. The objective of this study is to show the ability of QUELL to provide quench conditions relevant for ITER and to simulate the system performance, dealing in particular with the design aspects of the power supply, cryogenic system and heaters. The numerical analysis was performed with GANDALF - a 1-D code to analyze Dual Channel Cable-in-Conduit Conductors. A numerical convergence test and a comparison with another code and with analytical results have confirmed the validity of the simulations.

  3. Gestion des ressources hydriques adaptee aux changements climatiques pour la production optimale d'hydroelectricite. Etude de cas: Bassin versant de la riviere Manicouagan

    NASA Astrophysics Data System (ADS)

    Haguma, Didier

    Il est dorenavant etabli que les changements climatiques auront des repercussions sur les ressources en eau. La situation est preoccupante pour le secteur de production d'energie hydroelectrique, car l'eau constitue le moteur pour generer cette forme d'energie. Il sera important d'adapter les regles de gestion et/ou les installations des systemes hydriques, afin de minimiser les impacts negatifs et/ou pour capitaliser sur les retombees positives que les changements climatiques pourront apporter. Les travaux de la presente recherche s'interessent au developpement d'une methode de gestion des systemes hydriques qui tient compte des projections climatiques pour mieux anticiper les impacts de l'evolution du climat sur la production d'hydroelectricite et d'etablir des strategies d'adaptation aux changements climatiques. Le domaine d'etude est le bassin versant de la riviere Manicouagan situe dans la partie centrale du Quebec. Une nouvelle approche d'optimisation des ressources hydriques dans le contexte des changements climatiques est proposee. L'approche traite le probleme de la saisonnalite et de la non-stationnarite du climat d'une maniere explicite pour representer l'incertitude rattachee a un ensemble des projections climatiques. Cette approche permet d'integrer les projections climatiques dans le probleme d'optimisation des ressources en eau pour une gestion a long terme des systemes hydriques et de developper des strategies d'adaptation de ces systemes aux changements climatiques. Les resultats montrent que les impacts des changements climatiques sur le regime hydrologique du bassin de la riviere Manicouagan seraient le devancement et l'attenuation de la crue printaniere et l'augmentation du volume annuel d'apports. L'adaptation des regles de gestion du systeme hydrique engendrerait une hausse de la production hydroelectrique. Neanmoins, une perte de la performance des installations existantes du systeme hydrique serait observee a cause de l'augmentation des

  4. Developpement D'un Modele Climatique Regional: Fizr Simulation des Conditions de Janvier de la Cote Ouest Nord Americaine

    1995-11-01

    Le sujet de cette these concerne la modelisation numerique du climat regional. L'objectif principal de l'exercice est de developper un modele climatique regional ayant les capacites de simuler des phenomenes de meso-echelle spatiale. Notre domaine d'etude se situe sur la Cote Ouest nord americaine. Ce dernier a retenu notre attention a cause de la complexite du relief et de son controle sur le climat. Les raisons qui motivent cette etude sont multiples: d'une part, nous ne pouvons pas augmenter, en pratique, la faible resolution spatiale des modeles de la circulation generale de l'atmosphere (MCG) sans augmenter a outrance les couts d'integration et, d'autre part, la gestion de l'environnement exige de plus en plus de donnees climatiques regionales determinees avec une meilleure resolution spatiale. Jusqu'alors, les MCG constituaient les modeles les plus estimes pour leurs aptitudes a simuler le climat ainsi que les changements climatiques mondiaux. Toutefois, les phenomenes climatiques de fine echelle echappent encore aux MCG a cause de leur faible resolution spatiale. De plus, les repercussions socio-economiques des modifications possibles des climats sont etroitement liees a des phenomenes imperceptibles par les MCG actuels. Afin de circonvenir certains problemes inherents a la resolution, une approche pratique vise a prendre un domaine spatial limite d'un MCG et a y imbriquer un autre modele numerique possedant, lui, un maillage de haute resolution spatiale. Ce processus d'imbrication implique alors une nouvelle simulation numerique. Cette "retro-simulation" est guidee dans le domaine restreint a partir de pieces d'informations fournies par le MCG et forcee par des mecanismes pris en charge uniquement par le modele imbrique. Ainsi, afin de raffiner la precision spatiale des previsions climatiques de grande echelle, nous developpons ici un modele numerique appele FIZR, permettant d'obtenir de l'information climatique regionale valide a la fine echelle spatiale

    Leger, Michel T.

    Les activites humaines energivores telles l'utilisation intensive de l'automobile, la surconsommation de biens et l'usage excessif d'electricite contribuent aux changements climatiques et autres problemes environnementaux. Bien que plusieurs recherches rapportent que l'etre humain est de plus en plus conscient de ses impacts sur le climat de la planete, ces memes recherches indiquent qu'en general, les gens continuent a se comporter de facon non ecologique. Que ce soit a l'ecole ou dans la communaute, plusieurs chercheurs en education relative a l'environnement estiment qu'une personne bien intentionnee est capable d'adopter des comportements plus respectueux de l'environnement. Le but de cette these etait de comprendre le processus d'integration de comportements d'attenuation des changements climatiques dans des familles. A cette fin, nous nous sommes fixe deux objectifs : 1) decrire les competences et les procedes qui favorisent l'adoption de comportements d'attenuation des changements climatiques dans des familles et 2) decrire les facteurs et les dynamiques familiales qui facilitent et limitent l'adoption de comportements d'attenuation des changements climatiques dans des familles. Des familles ont ete invitees a essayer des comportements personnels et collectifs d'attenuation des changements climatiques de sorte a integrer des modes de vie plus ecologiques. Sur une periode de huit mois, nous avons suivi leur experience de changement afin de mieux comprendre comment se produit le processus de changement dans des familles qui decident volontairement d'adopter des comportements d'attenuation des changements climatiques. Apres leur avoir fourni quelques connaissances de base sur les changements climatiques, nous avons observe le vecu de changement des familles durant huit mois d'essais a l'aide de journaux reflexifs, d'entretiens d'explicitation et du journal du chercheur. La these comporte trois articles scientifiques. Dans le premier article, nous presentons une

    Summary La peau, barrière protectrice de l’organisme, est très exposée aux agressions et donc aux brûlures. Le but de ce travail est d’apprécier les particularités des séquelles de brûlure cervicofaciales chez l’enfant en milieu sub-saharien et d’évaluer leur prise en charge. Il s’agit d’une étude rétrospective réalisée dans le service de Chirurgie Pédiatrique du Centre Hospitalo-universitaire Aristide Le Dantec de Dakar (Sénégal). Vingt-sept dossiers de patients ont été colligés entre mai 2001 et avril 2008. L’âge moyen lors de la consultation était de 6,7 ans et le sex ratio m:f de 1,7:1. La topographie des séquelles se répartit ainsi: la face (66,7%), le cou (29,6%) et le cuir chevelu (11,1%). Concernant le type de séquelles, les brides prédominaient (33,3%), suivies des cicatrices chéloïdiennes ou hypertrophiques (25,9%), des ectropions de paupières (18,5%), des alopécies du cuir chevelu (11,1%), des ulcérations chroniques (7,4%) et de dyschromie (3,7%). Le traitement a été chirurgical dans 55,7% des cas: plasties en Z suivies ou non d’une greffe de peau pour les brides et libération de bride suivie d’une greffe pour les ectropions de paupières. Pour ce qui concerne les patients opérés, la morbidité opératoire a été de 20% et la mortalité opératoire nulle. Les cicatrices chéloïdiennes ont fait l’objet d’un traitement médical par infiltrations de dermocorticoïdes. Au-delà de l’urgence, les brûlures cervicofaciales de l’enfant entraînent un préjudice esthétique et fonctionnel important. L’amélioration de leur pronostic passe par la qualité des premiers soins et par la sensibilisation des parents aux risques d’accidents domestiques. PMID:21991239

  9. Les perspectives de l'énergie nucléaire dans le cadre des changements climatiquesThe future of nuclear energy in relation with climate change

    2001-12-01

    Electronuclear energy associated with hydrogen production can replace fossil fuels while emitting as few greenhouse gases as renewable energies. Besides waste management for which a solution has to be rapidly demonstrated, other key issues are to be examined to complete the demonstration of the viability of electronuclear energy. First, waste management and evolution of plutonium and its daughters must be considered together. A basic study has already been performed but what else to be done is huge and cannot be achieved in France (because of its geological and geographic features, because of the rural distribution of its population, etc.), except if a substantial and quite focused endeavour could bring concerned populations and workers, protection and confidence - which requires from the latter, represented by their elected representatives and thus by a public authority, that they work out "a general protection and confidence criterion for concerned populations and workers". The unique solution in order to protect public health from a potential major danger is to bury as soon as possible all of the ultimate waste products, keeping in mind all of the unfavourable factors such as residual power of these products, their mobility in the confining geological beds and then through aquifers. There are so many categories of waste products whose treatment requires different durations, that storing is necessary in order to make them compatible after sorting by means of chemical separation (called reprocessing). Among all of these potential risks, the present-day most serious one, by far, is that of plutonium and its daughters, which are the most potentially radiotoxic. The unique solution consists in a separation of plutonium (and its daughters), followed by its fissions until a rather complete reduction in a product able to be buried after dilution in a matrix (for example, vitrification). But that solution faces serious handicaps. The examination of waste products and especially of the potentially most dangerous and difficult to treat, that is plutonium (and its daughters), leads thus necessarily to a 'plutonium (and its daughters) plan'. Nuclear safety is a major preoccupation. The French electronuclear stock is a recognized success and when it will be necessary to replace the latter, it will be possible to use the European Pressurized Reactor French-German project; the latter includes protections against very unlikely events and its implementation would be a factor of substantial progress for nuclear safety. Radioprotection, as well as its scientific bases, epidemiology and radiobiology, have funding that is not at the level of the funding devoted to the technical and industrial realizations. As for proliferation, it can be noticed that the countries that have recently at their disposal nuclear weapons have done it independently of their eventual electronuclear stock and furthermore each of the latter used a different scientific and technical process. As for the eventual relations between reprocessing and proliferation, the problem should be solved if the total produced plutonium could be denatured in the reactors of the electronuclear stock. It must be noticed that the major potential danger would rather be the dispersion of radiotoxic products about which the department of ONU in charge of all of these questions is aware of increasing contraband from eastern Europe since some years.

  10. EDITORIAL: Perspectives Perspectives

    Dewhurst, Richard

    2011-05-01

    In this issue, we are delighted to publish the second in a series of articles under the banner of Perspectives. The series commenced in late 2008, when Udo Kaatze [1] published an article about the powerful technique of dielectric spectrometry for liquid measurements. In addition to examining the very wide frequency range from 10-6 Hz to 10-13 Hz, an outline of possible future developments was presented. Some challenging tasks for the future were briefly outlined. The format of the article was different to the usual style of a contributed paper or review article. Instead, it represented a short summary of recent work in the field and offered a viewpoint of an expert in the area. Its commentary noted several milestones that had been recently achieved, and then looked to the future. The Perspective format allowed the author to provide some opinion about the challenges of the future not normally permitted in a Topical Review. The journal now intends to publish several more Perspectives. For example, in this issue David Birch [2] presents a Perspective about another important measurement science, namely fluorescence detections and their future directions. These are based on an old technique which provided the basis for detecting the presence of molecular species. Successful research led to an understanding and description of the phenomenon of molecular fluorescence in terms of excited state energies, transitions, symmetries and rate parameters. More recently, using fluorescence as a probe, and with the exploitation of new technologies, new applications have included the study of protein, vision, photosynthesis, membranes and DNA. Indeed nowhere has fluorescence had more impact than in the biosciences. Once again, the intention of the Perspective article has been to highlight recent milestones within the field. Importantly, it also indicates some of the future challenges. Such Perspectives are an occasional series. They are not intended to deflect from the balance of

    Les séquelles de brûlures cervicales représentent une entité fréquente des séquelles de brûlure, elles affectent la fonction, l'esthétique et l’état psychologique des patients et peuvent être de traitement difficile. Il s'agit d'une étude rétrospective étalée sur 5 ans de Mars 2009 au Octobre2014, réalisée au centre national des brûlés et de chirurgie plastique au CHU Ibn Rochd Casablanca. Nous avons analysé les caractéristiques épidémiologiqueset cliniques ainsi que les indications et les résultats thérapeutiques chez 300 patients présentant des rétractions cervicales post-brûlure, suivis dans notre formation. Les jeunes femmes étaient le plus souvent touchées (56%). la brûlure thermique par flamme de butane dans le cadre d'accident domestique était l’étiologie la plus fréquente (91%).75% des patients ont été pris en charge dans un délai de 18 mois après avoir présenté une incapacité fonctionnelle. Les brides cervicales modérées et sévères sont les plus fréquentes et représentent respectivement 60% et 16% des cas. Le traitement chirurgical a fait appel aux greffes cutanées dans 67%des cas, aux plasties locales dans 24%des cas et aux lambeaux dans 24% des cas, les résultats sont jugés bons dans 75%des cas et moyens dans 18% des cas, tandis que les cas restants (7%) ont nécessité une reprise chirurgicale. Le traitement des brides cervicales doit être associé à un programme de rééducation adapté, afin d'assurer la pérennité des résultats fonctionnels et esthétiques. PMID:26301017

    PubMed

    Godard, Béatrice; Hunt, Matthew; Moube, Zéphirin

    2014-03-01

    La recherche en santé mondiale s'inscrit dans une volonté de mobiliser des connaissances au service d'interventions et de politiques publiques pour l'atteinte équitable du bien-être commun, notamment en matière de santé. Elle joue un rôle primordial en ce sens, en favorisant l'implication des communautés et leur autonomisation et de nombreuses lignes directrices supportent un tel partenariat. Néanmoins, certains enjeux éthiques sont liés au financement de la recherche, aux environnements de recherche, à la priorisation des problématiques de recherche, aux mécanismes d'évaluation éthique posent souvent un problème de justice sociale au niveau de la redistribution des ressources et de la reconnaissance des différences culturelles. Comment alors déterminer quelle est la façon « idéale » d'agir en tenant compte de la globalité des individus et du pluralisme culturel des sociétés pour « bien faire », pour satisfaire l'exigence de l'équité? Une réflexion et une démarche éthique demeurent essentielles, ainsi qu'un dialogue entre les chercheurs du Nord et du Sud, et leurs autres partenaires que sont les décideurs, les responsables locaux et les communautés. Un tel dialogue, établi dans un continuum du développement de projets de recherche à leur pérennité, peut grandement contribuer à limiter les problèmes de justice sociale et à viser un développement plus égalitaire des savoirs scientifiques. Plusieurs chercheurs se sont déjà engagés dans cette voie, et leurs initiatives devraient être encouragées pour mettre les nouveaux savoirs au service des populations. PMID:24594489

    Cette étude rapporte les aspects cliniques et évolutifs des séquelles pulmonaires tuberculeuses (SPT) opérées chez les séropositifs (VIH+). Il s'agit d'une étude prospective transversale réalisée entre Novembre 2005 et Octobre 2012. Elle a porté sur 20 patients VIH+, ayant dans leurs antécédents, une tuberculose pulmonaire (TP) traitée et déclarée guérie, et admise dans ladite période pour une chirurgie de la SPT secondaire. Une enquête sérologique VIH a été réalisée systématiquement au cours du bilan pré-opératoire. Le diagnostic pré-opératoire de la SPT, la mortalité, les complications post- opératoires (CPOP), le séjour hospitalier, le suivi à moyen terme des STP opérées ont été évalués. Les séropositifs étaient VIH1+ (n = 12; 60%), VIH1&2+ (n = 4; 20%) et VIH2+ (n = 4; 20%). La durée moyenne d’évolution des STP était de 26,22 ± 21,3 mois. Les STP étaient les pyothorax ou pleurésies enkystées (n = 16; 80%), le poumon détruit (n = 2;10%) et les dilatations de bronches (n = 2;10%). Les VIH+ ne présentaient pas d'aspergillome pulmonaire. Le séjour hospitalier moyen était 13,1 ± 10,2 jours. Le suivi total était de 82 patients-année avec une moyenne de suivi de 4,2 ± 2,3 ans (extrêmes: 1 et 7 ans). Le taux de mortalité à court et moyen terme était nul. Aucun décès post-opératoire immédiat n'a été noté. Les CPOP immédiates étaient les bullages prolongés chez 75% des immunodéprimés. Les CPOP tardives (n = 3) étaient un syndrome restrictif pulmonaire, un pyothorax persistant et une pachypleurite résiduelle restrictive. A court terme, le taux de guérison radiologique était de 80% (n = 16). PMID:24932331

    Summary Nous avons mené une étude rétrospective s’étendant de septembre 2004 à septembre 2012 sur les données de à propos de 84 patients présentant des séquelles de brûlure majeures de la main. Ces patients étaient traités chirurgicalement par une greffe de peau totale. Le but de cette étude est, donc, d’insister sur la simplicité de cette technique et surtout son efficacité et sa fiabilité. L’âge moyen de la survenue de la brûlure était de 4 ans. L’âge moyen de nos patients était de 18,3 ans (2-62 ans), avec prédominance masculine dans 60% des cas. L’agent causal le plus fréquent était un agent thermique - le plus souvent un liquide chaud (56%). Le délai moyen entre la fin de la cicatrisation et la prise en charge des séquelles était de 36 mois (2 mois - 16 ans). Dans 69 cas (82.5%), les lésions étaient localisées au niveau de la face palmaire de la main. Les séquelles ont été dominées par les rétractions digitales (65%) dont le déficit fonctionnel est évident. Une greffe de peau totale a été réalisée chez tous nos patients après libération des brides et excision des placards cicatriciels. Les rétractions commissurales ont été traitées par des plasties en Z. Dans 95% des cas, le prélèvement de peau totale était réalisé au niveau du pli inguinal. Le recul moyen était de 5,5 ans (1-8 ans). 11 patients ont été perdus de vu. Les résultats après cicatrisation complète et rééducation ont été jugés satisfaisants (bons) dans 62 cas (85%), et assez bons dans 11 cas (15%). Un traitement initial bien conduit et effectué dans les meilleures conditions permet non seulement de réduire le nombre de séquelles des brûlures mais encore de les rendre moins sévères.

    Summary Les séquelles de brûlures de la main sont encore fréquentes dans les pays à ressources limitées. Trente-deux patients, représentant 38 mains, ont été admis et traités, entre le 1er décembre 2010 et le 1er mai 2014 aux Cliniques Universitaires de Kinshasa en République Démocratique du Congo (RDC). nous avons observé 22 patients (69 %) dans le groupe de jeunes (patients âgés de moins de 18 ans), et 10 patients (31 %) chez les adultes (18 à 59 ans). Aucun patient dans le groupe de seniors (60 ans et plus) n’a été observé. Dans le groupe de jeunes, la tranche d’âge de 1 à 5 ans a été la plus atteinte avec 13 malades (40 %). l’accident à la maison était le plus fréquent (72 %). le mécanisme de la brûlure était le plus souvent thermique par flammes (51 %) ou par liquide chaud (34 %). les rétractions et brides sont les lésions le plus observées (84 %). la rétraction dorsale globale « main en griffe» est observée chez 40 % de patients traités, associée à des cicatrices hypertrophiques et chéloïdiennes dans 84 % de cas. Chez les 32 mains traitées chirurgicalement, des excision-greffes ont été réalisées dans 43,7 %, des lambeaux locaux dans 43,7 % et des lambeaux à distance dans 12,5 % de cas. A la sortie de l’hôpital, 84 % de « bons » résultats ont été observés. le suivi a été de 18 mois. le traitement des séquelles de brûlures de la main est possible dans ces pays, exemple de la rDC. Mais les défis à surmonter dans ces pays sont nombreux : la faible accessibilité aux techniques actuelles de la chirurgie plastique, la prise en charge initiale inadéquate des brûlures, la pauvreté.

    Si Moussa, Azzedine; Tupin, Frédéric

    1999-11-01

    The islands of Mauritius and Réunion have contrasting educational policies. This article examines, from a comparative perspective, not only the impact of political decisions on education but also the way in which the different educational systems in the two islands affect the democratisation of learning. In order to do this, the authors compare the educational trajectories of different pupils from a range of schools in Mauritius and Réunion. Using a combination of quantitative and qualitative approaches, it is possible to show that the expected social effects are moderated in the course of teaching. While the adoption of mass education is a prerequisite for democratisation, it must be recognised that systems also operate selectively with regard to variables such as sex, age or social origin, depending on what transpires in schools on a daily basis.

  7. Les cyclones tropicaux et le changement climatique

    NASA Astrophysics Data System (ADS)

    André, Jean-Claude; Royer, Jean-François; Chauvin, Fabrice

    2008-09-01

    Results from observations and modelling studies, a number of which having been used to support the conclusions of the IPCC fourth assessment report, are presented. For the past and present-day (since 1970) periods, the increase of strong cyclonic activity over the North Atlantic Ocean appears to be in good correlation with increasing temperature of the ocean surface. For regions where observational data are of lesser quality, the increasing trend is less clear. In fact, assessing long-term changes is made difficult due to both the multi-decennial natural variability and the lesser coverage of observations before satellites were made available. Indirect observational data, such as those derived from quantitative estimations of damage caused by tropical cyclones, suffer from many artefacts and do not allow the resolving of the issue either. For the future, only numerical three-dimensional climate models can be used. They nevertheless run presently with too-large grid-sizes, so that their results are still not converging. Various simulations lead indeed to different results, and it is very often difficult to find the physical reasons for these differences. One concludes by indicating some ways through which numerical simulations could be improved, leading to a decrease of uncertainties affecting the prediction of cyclonic activity over the next decades.

  11. The Polyvagal Perspective

    PubMed Central

    Porges, Stephen W.

    2007-01-01

    The Polyvagal Theory introduced a new perspective relating autonomic function to behavior that included an appreciation of autonomic nervous system as a “system,” the identification of neural circuits involved in the regulation of autonomic state, and an interpretation of autonomic reactivity as adaptive within the context of the phylogeny of the vertebrate autonomic nervous system. The paper has two objectives: First, to provide an explicit statement of the theory; and second, to introduce the features of a polyvagal perspective. The polyvagal perspective emphasizes how an understanding of neurophysiological mechanisms and phylogenetic shifts in neural regulation, leads to different questions, paradigms, explanations, and conclusions regarding autonomic function in biobehavioral processes than peripheral models. Foremost, the polyvagal perspective emphasizes the importance of phylogenetic changes in the neural structures regulating the autonomic nervous system and how these phylogenetic shifts provide insights into the adaptive function and the neural regulation of the two vagal systems PMID:17049418

  12. Disciplinary Perspectives on Archaeoastronomy

    This chapter examines the contributions of major academic disciplines to archaeoastronomy, beginning with a consideration of several indicators of the participation of scholars from various fields. We then consider examples of research from astronomy and the physical sciences; anthropology, archaeology, and the social sciences; and the historical disciplines to see how they reflect their disciplinary perspectives. The questions drawn from these varied disciplinary perspectives stimulate different strands of research, enriching the study of astronomies in cultures.

  13. Perception of Perspective Angles

    PubMed Central

    2015-01-01

    We perceive perspective angles, that is, angles that have an orientation in depth, differently from what they are in physical space. Extreme examples are angles between rails of a railway line or between lane dividers of a long and straight road. In this study, subjects judged perspective angles between bars lying on the floor of the laboratory. Perspective angles were also estimated from pictures taken from the same point of view. Converging and diverging angles were judged to test three models of visual space. Four subjects evaluated the perspective angles by matching them to nonperspective angles, that is, angles between the legs of a compass oriented in the frontal plane. All subjects judged both converging and diverging angles larger than the physical angle and smaller than the angles in the proximal stimuli. A model of shallow visual space describes the results. According to the model, lines parallel to visual lines, vanishing at infinity in physical space, converge to visual lines in visual space. The perceived shape of perspective angles is incompatible with the perceived length and width of the bars. The results have significance for models of visual perception and practical implications for driving and flying in poor visibility conditions. PMID:27433312

    In his presidential address to the Southwestern Surgical Congress, he examines surgery as a profession from three different perspectives: his experience as a patient, a surgeon, and a photographer. He uses photography to illustrate the importance of perspective and illumination. He respectfully suggests that we should consciously choose to reframe the profession from a different perspective that accurately reflects its beauty. He also advises that we take effort to shine a gentle, soft light on the profession, a light that will reveal the beauty, the true beauty, of the profession. And finally, he submits that it is our responsibility to consciously and faithfully maintain and defend the profession from enemies inside and outside its borders. PMID:26520870

  14. The architect's perspective on the tour and map perspective.

    PubMed

    Papadopoulou, Athina

    2015-09-01

    Literature in linguistics suggests that when people are asked to provide an oral spatial description, they usually provide a body-centered narrative; they adopt a Tour Perspective, that is, an imaginary tour of the space rather than a Map Perspective, that is, a description focused on spatial relations as seen from above (Linde and Labov in Language 51(1):924-939, 1975; Howald in Discursive constraints on space in narrative: evidence from guilty plea discourse, eVox 3, 2009). I conducted a pilot experiment to address the following questions: Does the formal knowledge of architects--their familiarity with plan drawings and maps--override the tendency to adopt the tour perspective? Does the tour perspective depend on the actual experience of space? Twenty-two graduate students in architecture were asked to respond to the following questions: (1) "Can you describe the layout of your apartment?" (2) "Can you describe the layout of an ideal apartment?" In the responses to the first question most participants used the tour perspective. In the responses to the second question most participants used the map perspective. The results provide evidence that architects' formal knowledge does not override the preference of the tour perspective in descriptions of experienced space. Moreover, that the tour perspective is associated with the actual experience of space. PMID:26216760

  16. Rowing competitions and perspective

    NASA Astrophysics Data System (ADS)

    Flores, Alfinio; Bernhardt, Stephen A.; Shipman, Henry L.

    2015-02-01

    This paper is about integrating the use of graphing technology (specifically, GeoGebra) with principles of motion, principles of perspective, and the concept of vanishing points to model a dynamic event. Students were asked to analyse video images of a rowing competition filmed with a single camera positioned perpendicular to the race. The fixed position of the camera in such races makes it difficult to determine whether a scull closer to the camera is actually overtaking another, more distant scull. The paper illustrates how students in their first year at the university can integrate the use of technology, science, mathematics, and writing to solve a real world problem involving motion.

    The emergence of Zika virus (ZiV), a mosquito borne Flavivirus like dengue (DEN) and chikungunya (CHIK), in Brazil in 2014 and its spread to various countries have led to a global health emergency. Aedes aegypti is the major vector for ZiV. Fast dissemination of this virus in different geographical areas posses a major threat especially to regions where the population lacks herd immunity against the ZiV and there is abundance of Aedes mosquitoes. In this review, we focus on current global scenario, epidemiology, biology, diagnostic challenges and remedial measures for ZiVconsidering the Indian perspective. PMID:27487998

    2012-12-01

    Nonadiabatic dynamics—nuclear motion evolving on multiple potential energy surfaces—has captivated the interest of chemists for decades. Exciting advances in experimentation and theory have combined to greatly enhance our understanding of the rates and pathways of nonadiabatic chemical transformations. Nevertheless, there is a growing urgency for further development of theories that are practical and yet capable of reliable predictions, driven by fields such as solar energy, interstellar and atmospheric chemistry, photochemistry, vision, single molecule electronics, radiation damage, and many more. This Perspective examines the most significant theoretical and computational obstacles to achieving this goal, and suggests some possible strategies that may prove fruitful.

    Fraser, Steven; Lundh, Erik; Davies, Rachel; Eckstein, Jutta; Larsen, Diana; Vilkki, Kati

    There are many perspectives to agile coaching including: growing coaching expertise, selecting the appropriate coach for your context; and eva luating value. A coach is often an itinerant who may observe, mentor, negotiate, influence, lead, and/or architect everything from team organization to system architecture. With roots in diverse fields ranging from technology to sociology coaches have differing motivations and experience bases. This panel will bring together coaches to debate and discuss various perspectives on agile coaching. Some of the questions to be addressed will include: What are the skills required for effective coaching? What should be the expectations for teams or individu als being coached? Should coaches be: a corporate resource (internal team of consultants working with multiple internal teams); an integral part of a specific team; or external contractors? How should coaches exercise influence and au thority? How should management assess the value of a coaching engagement? Do you have what it takes to be a coach? - This panel will bring together sea soned agile coaches to offer their experience and advice on how to be the best you can be!

They were born roughly between 1977 and 2000, but that is definitely not their only defining factor. But who is this group, and what do they have to do with the future of the space program and the Johnson Space Center (JSC)? During 2007, a group of Gen Yers at JSC participated on a committee to address the NASA Headquarters strategic communications plan. Fitzpatrick, along with his co-authors, created a presentation to share the Gen Yers' perspective on their generation in conjunction with the strategic communications strategy released.

    2013-06-01

    Effective communication with a mobile robot using speech is a difficult problem even when you can control the auditory scene. Robot self-noise or ego noise, echoes and reverberation, and human interference are all common sources of decreased intelligibility. Moreover, in real-world settings, these problems are routinely aggravated by a variety of sources of background noise. Military scenarios can be punctuated by high decibel noise from materiel and weaponry that would easily overwhelm a robot's normal speaking volume. Moreover, in nonmilitary settings, fans, computers, alarms, and transportation noise can cause enough interference to make a traditional speech interface unusable. This work presents and evaluates a prototype robotic interface that uses perspective taking to estimate the effectiveness of its own speech presentation and takes steps to improve intelligibility for human listeners.

    In his recent paper about understanding ethical issues, Boyd suggests that traditional approaches based on principles or people are understood better in terms of perspectives, especially the perspective‐based approach of hermeneutics, which he uses for conversation rather than controversy. However, we find that Boyd's undefined contrast between conversation and controversy does not point to any improvement in communication: disputes occur during conversation and controversy may be conducted in gentle tones. We agree with Boyd, that being prepared to listen and learn are excellent attitudes, but his vague attempts to establish these and similar virtues in hermeneutic theory are not plausible. Additionally, the current controversy about the use of human embryos in stem cell therapy research shows Boyd missing the opportunity to illustrate how conversation would improve understanding.

The participants were Imogene King, Nola Pender, Betty Neuman, Martha E. Rogers, Afaf Meleis and Rosemarie Rizzo Parse. The goal of the conferences was to present views on the meaning of health from different perspectives. The panel discussion provided the nurse leaders with an opportunity to engage in a dialogue about health. Five of the participants answered the questions posed and the conference keynote speaker Afaf Meleis responded. Four questions were posed to the panel relating to the meaning of health, the uniqueness of nursing, and nurse-person relationships. The dialogue of the panel discussion follows. PMID:2000198

  13. Brain resuscitation. Ethical perspectives.

    PubMed

    Omery, A; Caswell, D

    1989-03-01

    Brain resuscitation is the newest in a long line of treatment protocols that is designed to aid us in sustaining not just life, but quality life in the critical care setting. Like other, previously established protocols, it is not value free. Its implementation brings ethical considerations that must be addressed. If the issues are not addressed, there is the real danger that the resulting moral dilemmas will overwhelm the nurse. In brain resuscitation, there are at least three ethical issues that must be recognized. These are the role of resuscitation in the life process, allocation of scarce resources, and participation in research. To address these issues, nurses will have to be aware of the ethical principle and/or perspectives involved. For some of these issues, the solutions will have to come from nursing's national organizations, such as the American Association of Critical Care Nurses. Other solutions presented will require the nurse to come to an individual decision regarding the ethics of brain resuscitation. The journey to the conclusion of this discussion will end with disappointment for those who sought an algorhythm or decision tree with which to make definitive decisions in regard to ethical decisions about brain resuscitation. To have assumed that such an absolute discussion in regard to the ethical perspectives related to brain resuscitation is possible or even desirable would have been to deny the moral/ethical responsibilities of the nurse who practices in a critical care setting. While these ethical responsibilities can be overwhelmingly burdensome, they can also be opportunities. They can be positive opportunities for our health care colleagues, our patients, and ourselves.

  20. Perspective View, Garlock Fault

    2000-01-01

    California's Garlock Fault, marking the northwestern boundary of the Mojave Desert, lies at the foot of the mountains, running from the lower right to the top center of this image, which was created with data from NASA's shuttle Radar Topography Mission (SRTM), flown in February 2000. The data will be used by geologists studying fault dynamics and landforms resulting from active tectonics. These mountains are the southern end of the Sierra Nevada and the prominent canyon emerging at the lower right is Lone Tree canyon. In the distance, the San Gabriel Mountains cut across from the leftside of the image. At their base lies the San Andreas Fault which meets the Garlock Fault near the left edge at Tejon Pass. The dark linear feature running from lower right to upper left is State Highway 14 leading from the town of Mojave in the distance to Inyokern and the Owens Valley in the north. The lighter parallel lines are dirt roads related to power lines and the Los Angeles Aqueduct which run along the base of the mountains.

    This type of display adds the important dimension of elevation to the study of land use and environmental processes as observed in satellite images. The perspective view was created by draping a Landsat satellite image over an SRTM elevation model. Topography is exaggerated 1.5 times vertically. The Landsat image was provided by the United States Geological Survey's Earth Resources Observations Systems (EROS) Data Center, Sioux Falls, South Dakota.

    Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on February 11,2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast

  1. Time in perspective.

    PubMed

    Gorea, Andrei; Hau, Janice

    2013-08-01

    Perceptions of time and space are subject to strong contextual effects. Like their physical counterparts, they appear to be bound together. The perceived spatial extent of a constant retinal extent increases with its perceived distance from the observer. The perceived duration of a moving object increases with its covered angular trajectory. It follows that the perceived duration of moving objects covering identical angular trajectories should also increase with distance. Using three-dimensionally rendered balls rolling for 600 ms, 900 ms, and 1,200 ms and covering 5.5°, 11°, and 22° trajectories in fronto-parallel planes of a linear-perspective scene, we showed that perceived duration dilates by up to 50% as the fronto-parallel plane of the rolling ball recedes from the observer. Such time dilation is mostly contributed to by the smaller size of the distant ball. As in a three-dimensional world, objects' sizes and their covered trajectories per time unit decrease with distance, and as the two factors lead to opposite perceived-duration effects, the results suggest a form of time constancy in a three-dimensional world.

    Astrobiology, a new exciting interdisciplinary research field, seeks to unravel the origin and evolution of life wherever it might exist in the Universe. The current view of the origin of life on Earth is that it is strongly connected to the origin and evolution of our planet and, indeed, of the Universe as a whole. We are fortunate to be living in an era where centuries of speculation about the two ancient and fundamental problems: the origin of life and its prevalence in the Universe are being replaced by experimental science. The subject of Astrobiology can be approached from many different perspectives. This book is focused on abiogenic organic matter from the viewpoint of astronomy and planetary science and considers its potential relevance to the origins of life on Earth and elsewhere. Guided by the review papers in this book, the concluding chapter aims to identify key questions to motivate future research and stimulate astrobiological applications of current and future research facilities and space missions. Today’s rich array of new spacecraft, telescopes and dedicated scientists promises a steady flow of discoveries and insights that will ultimately lead us to the answers we seek.

  3. An intentional interpretive perspective

    PubMed Central

    Neuman, Paul

    2004-01-01

    To the extent that the concept of intention has been addressed within behavior analysis, descriptions of intention have been general and have not specifically included important distinctions that differentiate a behavior-analytic approach from vernacular definitions of intention. A fundamental difference between a behavior-analytic approach and most other psychological approaches is that other approaches focus on the necessity of intentions to explain behavior, whereas a behavior-analytic approach is directed at understanding the interplay between behavior and environment. Behavior-analytic interpretations include the relations between the observer's behavior and the environment. From a behavior-analytic perspective, an analysis of the observer's interpretations of an individual's behavior is inherent in the subsequent attribution of intention. The present agenda is to provide a behavior-analytic account of attributing intention that identifies the establishing conditions for speaking of intention. Also addressed is the extent to which we speak of intentions when the observed individual's behavior is contingency shaped or under instructional control. PMID:22478417

  4. Employer and consumer perspectives.

    McGhan, W F

    1998-11-01

    This paper reviews various published reports from surveys on employer opinion, perception of needs, and trends with regard to healthcare benefits; the consumer perspective regarding healthcare is also discussed. Surveys indicate that businesses want continuous evidence that high-quality healthcare can positively impact company profits. Employers and labor unions are demanding more cost-effective healthcare. At both employer and consumer levels, greater patient education is needed, as well as traditional educational media. Direct-to-consumer advertising and use of the World Wide Web are increasingly important in enabling consumers to participate more fully in their own lipid-related decision-making. Finally, the transition of lipid-lowering drugs to over-the-counter accessibility has great implications with respect to issues of patient preferences and willingness to pay in the evolving healthcare environment. Groups in the United States, such as the National Committee on Quality Assurance and the Foundation for Accountability, are setting standards and beginning to assess both process and outcomes in patient care. Further collaborative efforts are needed that raise standards of care and stimulate more cost-effective healthcare. The pharmacoeconomics and outcomes data gathered will, one hopes, also demonstrate to global businesses the positive financial impact of high-quality healthcare and appropriate lipid therapy.

    Background The purpose of this study was to explore the quality attributes required for effective telemedicine encounters from the perspective of the patient. Methods We used a multi-method (direct observation, focus groups, survey) field study to collect data from patients who had experienced telemedicine encounters. Multi-perspectives (researcher and provider) were used to interpret a rich set of data from both a research and practice perspective. Results The result of this field study is a taxonomy of quality attributes for telemedicine service encounters that prioritizes the attributes from the patient perspective. We identify opportunities to control the level of quality for each attribute (ie, who is responsible for control of each attribute and when control can be exerted in relation to the encounter process). This analysis reveals that many quality attributes are in the hands of various stakeholders, and all attributes can be addressed proactively to some degree before the encounter begins. Conclusion Identification of the quality attributes important to a telemedicine encounter from a patient perspective enables one to better design telemedicine encounters. This preliminary work not only identifies such attributes, but also ascertains who is best able to address quality issues prior to an encounter. For practitioners, explicit representation of the quality attributes of technology-based systems and processes and insight on controlling key attributes are essential to implementation, utilization, management, and common understanding.

  6. Decontamination: a microbiologist's perspective.

    PubMed

    Graham, G S

    1988-01-01

    The primary objective of decontamination is to protect healthcare workers who handle medical devices from infectious diseases that may be present on those devices. Ideally, the decontamination process should provide both cleaning and biocidal activity. A wide range of equipment, from automatic washer/sterilizers to semi-automated washer/sanitizers are commercially available to satisfy this need. The primary difference between these pieces of equipment, from a microbiology perspective, is in the level of safety they provide. A summary comparison of the decontamination methods is shown in Table 1. Without a doubt, steam sterilization as a method of decontamination provides a greater safety level than may be required. However, the question is, "Do disinfection and sanitization provide an adequate safety level?" Although items do not necessarily need to be sterile to be safe to handle, sterilization processes provide the greatest margin of safety because of the significant microbial lethality and the ability to effectively monitor the process via biological indicators. Sterilization effectively eliminates the concern regarding the nearly unanswerable question of bioburden. Unfortunately, not all items are capable of being processed through a washer/sterilizer. Therefore, consideration must be given to the process compatibility of each device. Disinfection processes provide the next level of safety. Unfortunately, there is no recognized or accepted method for quantitatively describing or monitoring a thermal disinfection process. As is the case with sterilization consideration must be given to the process compatibility of each device. Sanitization provides the lowest level of safety for the decontamination process.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:10285793

    Previous studies suggest that those who naturally vary their pronoun use over the course of expressive writing subsequently report the greatest improvements in physical and mental health. To explore possible perspective taking or perspective switching effects, two studies manipulated writing perspectives about emotional events from either a first-person, second-person, or third-person perspective. In Study 1, 55 students were randomly assigned to one of the three writing perspectives and were asked to write from the same perspective for three 5-minute writing sessions. In Study 2, 129 students wrote for three 5-minute sessions, one from each perspective in a counterbalanced order. The results showed that writing from a first-person perspective conferred more perceived benefits and was associated with using more cognitive mechanism words, whether engaged in perspective taking or perspective switching.

    Whether dietary fructose (as sucrose or high fructose corn syrup) has unique effects separate from its role as carbohydrate, or, in fact, whether it can be considered inherently harmful, even a toxin, has assumed prominence in nutrition. Much of the popular and scientific media have already decided against fructose and calls for regulation and taxation come from many quarters. There are conflicting data, however. Outcomes attributed to fructose - obesity, high triglycerides and other features of metabolic syndrome - are not found in every experimental test and may be more reliably caused by increased total carbohydrate. In this review, we try to put fructose in perspective by looking at the basic metabolic reactions. We conclude that fructose is best understood as part of carbohydrate metabolism. The pathways of fructose and glucose metabolism converge at the level of the triose-phosphates and, therefore, any downstream effects also occur with glucose. In addition, a substantial part of ingested fructose is turned to glucose. Regulation of fructose metabolism per se, is at the level of substrate control - the lower Km of fructokinase compared to glucokinase will affect the population of triose-phosphates. Generally deleterious effects of administering fructose alone suggest that fructose metabolism is normally controlled in part by glucose. Because the mechanisms of fructose effects are largely those of a carbohydrate, one has to ask what the proper control should be for experiments that compare fructose to glucose. In fact, there is a large literature showing benefits in replacing total carbohydrate with other nutrients, usually fat, and such experiments sensibly constitute the proper control for comparisons of the two sugars. In terms of public health, a rush to judgement analogous to the fat-cholesterol-heart story, is likely to have unpredictable outcome and unintended consequences.

  11. Growth outcome: nutritionist perspective.

    PubMed

    Agostoni, Carlo; Fattore, Giovanni

    2013-01-01

    Increasing evidence points to a fundamental role of early nutrition on rates of growth and development, and later health. We may identify three major fields of scientific interest and clinical application. (1) In developing countries poor growth is associated with greater risk of morbidity and mortality from infectious diseases, mainly lower respiratory infections and diarrhea. In these settings, failure to promote compensatory growth may have negative short-term consequences, and the nutritionist's task is the primary prevention of nutrient deficiencies to promote the full expression of the individual genetic potential, while allowing for recovery of early secondary functional deficiencies. (2) A second challenge for nutritionists is represented by the approach to growth impairments in rare disorders, ranging from congenital disorders to chronic infections. Most disorders are favorably influenced by improved nutritional status and better growth, and patients may satisfactorily reach adolescence, pubertal and reproductive age, up to ageing. Even for the less positive conditions, an improvement in the quality of life for families is in any case a rewarding aim. (3) A third challenge is represented by the definition of the role of nutrition on growth in physiological conditions for all individuals. Concern has been raised about the potential adverse long-term consequences of accelerated child growth rates, possibly resulting in a predisposition to develop non-communicable chronic diseases in the adult age. Accordingly, this hypothesis might explain the benefits of breastfeeding in terms of slower early growth, and the fetal origins hypothesis in terms of adverse postnatal catch-up growth in infants born small. Therefore, growth as viewed by a pediatric nutritionist perspective is a complex matter, ranging from the early stages of intrauterine development up to adult ages and ageing processes.

  12. Quelling Cabin Noise in Turboprop Aircraft via Active Control

    NASA Technical Reports Server (NTRS)

    Kincaid, Rex K.; Laba, Keith E.; Padula, Sharon L.

    1997-01-01

    Cabin noise in turboprop aircraft causes passenger discomfort, airframe fatigue, and employee scheduling constraints due to OSHA standards for exposure to high levels of noise. The noise levels in the cabins of turboprop aircraft are typically 10 to 30 decibels louder than commercial jet noise levels. However. unlike jet noise the turboprop noise spectrum is dominated by a few low frequency tones. Active structural acoustic control is a method in which the control inputs (used to reduce interior noise) are applied directly to a vibrating structural acoustic system. The control concept modeled in this work is the application of in-plane force inputs to piezoceramic patches bonded to the wall of a vibrating cylinder. The goal is to determine the force inputs and locations for the piezoceramic actuators so that: (1) the interior noise is effectively damped; (2) the level of vibration of the cylinder shell is not increased; and (3) the power requirements needed to drive the actuators are not excessive. Computational experiments for data taken from a computer generated model and from a laboratory test article at NASA Langley Research Center are provided.

    2006-05-01

    Although nurses from four different generations work closely together, tension may occur as the different generational perspectives result in misinterpretation and misunderstanding. Learning to create integrated and collegial relationships with people from different generations is a critical skill for nurses who work in multigenerational teams. This article will begin with a review of the historical perspective of the four generational cohorts currently in the workplace. This review will set a foundation for understanding each generation's unique set of work and personal values. Then the article will discuss various sources of multigenerational misunderstandings and conclude with a discussion of approaches to strengthen intergenerational work teams. The article will emphasize that learning to appreciate the diverse points of view, leverage the strengths, and value the differences in colleagues from various generations can enable individuals to form creative, adaptable, and cohesive work groups.

    2016-01-01

    Primary Health Networks (PHNs) have been tasked with two key objectives to be achieved through commissioning. Public value aims can be achieved by developing operational capability in the context of an authorising environment. Public value will need to focus on system level outcomes from multiple perspectives, including a consumer perspective. The authorising environment will require policymakers to allow time for PHNs to mature into their role. It will require an environment of effective collaboration amongst multiple stakeholders including consumers. The operational capability will need to ensure highly competent managers and clinical leadership working in a symbiotic relationship. Although some Medicare Locals demonstrated commissioning capacity and capability, this will need to be scaled up at-pace in the new healthcare landscape in order for PHNs to optimally fulfil their roles.

The ultimate viewpoint of the author is that regardless of the immediate or eventual implications of the work of Wallace and his coworkers, they have made a major contribution to the conceptual basis of exposure assessment. The author believes EPA's actions will need to be closely monitored as the new Clean Air Act regulations unfold in order to determine whether of not full advantage in effectively protecting public health will be obtained.

    2015-06-01

    In celebration of the 2014 Nobel Prize in Physiology or Medicine, this issue of Hippocampus includes a collection of commentaries from a broad range of perspectives on the significance of position coding neurons in the hippocampal region. From the perspective of this student of hippocampal physiology, it is argued that place cells and grid cells reflect the outcome of experiments that strongly select the information available and correspondingly observe singular "trigger features" of these neurons. Notably, however, in more naturalistic situations where multiple dimensions of information are available, hippocampal neurons have mixed selectivity wherein population-firing patterns reflect the organization of many features of experience. Thus, while discoveries on position coding were major breakthroughs in penetrating the hippocampal code, future studies exploring more complex behaviors hold the promise of revealing the full contribution of the hippocampal region to cognition and memory.

    PubMed

    Cuesta, Marta; Rämgård, Margareta

    2016-01-01

    Earlier research has shown that power relationships at workplaces are constructed by power structures. Processes related to power always influence the working conditions for (in this study in elderly care) the working groups involved. Power structures are central for intersectional analysis, in the sense that the intersectional perspective highlights aspects such as gender and ethnicity (subjective dimensions) and interrelates them to processes of power (objective dimension). This qualitative study aims to explore in what way an intersectional perspective could contribute to increased knowledge of power structures in a nursing home where the employees were mostly immigrants from different countries. By using reflexive dialogues related to an intersectional perspective, new knowledge which contributes to the employees' well-being could develop. Narrative analysis was the method used to conduct this study. Through a multi-stage focus group on six occasions over 6 months, the staff were engaged in intersectional and critical reflections about power relationship with the researchers, by identifying patterns in their professional activities that could be connected to their subjectivities (gender, ethnicity, etc.). The result of this study presents three themes that express the staff's experiences and connect these experiences to structural discrimination. 1) Intersectionality, knowledge, and experiences of professionalism; 2) Intersectionality, knowledge, and experiences of collaboration; and 3) Intersectionality, knowledge, and experiences of discrimination. The result demonstrates that an intersectional perspective reinforces the involved abilities, during the conversations, into being clear about, for example, their experiences of discrimination, and consequently developing a better understanding of their professionalism and collaboration. Such deeper reflections became possible through a process of consciousness raising, strengthening the employee's self

    In 1950, John Nash contributed a remarkable one-page PNAS article that defined and characterized a notion of equilibrium for n- person games. This notion, now called the "Nash equilibrium," has been widely applied and adapted in economics and other behavioral sciences. Indeed, game theory, with the Nash equilibrium as its centerpiece, is becoming the most prominent unifying theory of social science. In this perspective, we summarize the historical context and subsequent impact of Nash's contribution. PMID:15024100

    PubMed

    Suissa, Amnon Jacob

    2014-12-01

    The concept of cyberaddiction is far from being unanimously accepted by scientists (Ko, Yen, Yen, Chen, & Chen, 2012; Pezoa-Jares, Espinoza-Luna & Vasquez-Medina, 2012; Nadeau & et al. 2011; Perraton, Fusaro & Bonenfant, 2011. The same is true of addiction to videogames (Hellman, Schoenmakers, Nordstrom, & Van Holst 2013); Coulombe (2010); or to Facebook (Andreassen et al. 2012; Levard & Soulas, 2010). While certain researchers wished to see this condition included in the DSM-5, others question the operational and practical basis for the diagnostic criteria (Block, 2008). Through a review of litterature and results from research findings; the aim of this article is to propose a psychosocial perspective for the cyberaddiction phenomenon. By a psychosocial perspective, we mean the inclusion of social determinants (weak social ties, social exclusion, hyper individualism, poverty, unemployment, etc) and not only the individual characteristics associated with the disease model in the addiction field. To what extent social conditions and cyberaddiction behaviors constitute a potential pathology ? Can we include a psychosocial approach to gain a more general picture of this contemporary issue? In response to these questions, a contextualization and an attempt to define cyberaddiction will be followed by an analysis of some major issues in the development of this type of addiction. As a conclusion, a demonstration of the cycle of addiction on how people develop addictions, including cyberaddictions, will be done within a psychosocial perspective in order to seize the multifactorial aspects of this addiction.

  7. Perspective switching using theories and interpretations

    SciTech Connect

    Farmer, W.M.

    1996-12-31

    An important aspect of intelligence is the ability to switch perspectives. In the course of reasoning about a particular subject matter, it can be convenient to change from one perspective of the subject matter to another perspective, which is often at a different level of abstraction. For example, in some situations it may be advantageous to view a building as a collection of floors and in other situations as a collection of wings. If the arrangement of the rooms is not important for the task at hand, the building might be viewed as simply an unstructured collection of rooms. These are three perspectives on how a building can be decomposed. Utilizing multiple perspectives and freeing moving from one to another is a powerful method for both managing complexity and organizing knowledge. The key idea behind this method is to always employ the {open_quotes}right{close_quotes} perspective for each reasoning task. This talk will address the following two questions: (1) What logical machinery is needed to formalize perspective switching? (2) How can knowledge associated with one perspective be retrieved for use with another perspective?

  9. Science, technology and ethics: from critical perspective to dialectical perspective.

    PubMed

    Lavelle, Sylvain

    2005-06-01

    It has been agreed upon, according to critical perspective, to distinguish the problems raised by scientific issues on the one hand and the problems raised by moral issues on the other. This distinction, at the genesis of theoretical ideology, postulates that experimental science is mere knowledge which, since it has nothing to do with action, cannot raise a moral problem. Yet the use of experimental techniques turns out to be a necessary means, although an insufficient one, to put to the test and to confirm the theoretical hypothesis of science. Thus, those techniques produce perceptible effects which can be assimilated to genuine transformation and are consequently capable of raising moral problems. It follows that the technical imperative of science can be conditioned by a moral imperative of technique, which leads to modification of the object of the research and dubs it, a dialectical object. It is, however, advisable to effect a demarcation between that which, within the frame work of research in experimental science, can pose a moral problem and which cannot. The criterion of refusability of practical projects, by analogy with Popper's criterion of refutability of theoretical conjectures, allows for this demarcation to be implemented. It postulates that only the technical projects of science, apart from scientific theories, can pose a moral problem or can be recognized as moral, providing that the conditions of a possible ethical refusal can be expressed. From the analysis and the synthesis of heterogeneous possibilities, dialectical perspective thus outlined represents an endeavour to go beyond critical perspective, while trying to seek an intermediary channel between the "progressist dogmatism" of science and the obscurantist scepticism" of morals.

  11. Current Perspectives on Cognitive Diversity.

    PubMed

    Bender, Andrea; Beller, Sieghard

    2016-01-01

    To what extent is cognition influenced by a person's cultural background? This question has remained controversial in large fields of the cognitive sciences, including cognitive psychology, and is also underexplored in anthropology. In this perspective article, findings from a recent wave of cross-cultural studies will be outlined with respect to three aspects of cognition: perception and categorization, number representation and counting, and explanatory frameworks and beliefs. Identifying similarities and differences between these domains allows for general conclusions regarding cognitive diversity and helps to highlight the importance of culturally shaped content for a comprehensive understanding of cognition.

    Dodds, Rosemary; Neiger, Deborah

    2014-10-01

    In light of the recent NCT petition to Health Minister Dr Dan Poulter MP to update guidelines for the diagnosis and treatment of tongue-tied babies to avoid stress and difficulties feeding for babies and their families, discussion has been sparked amongst mothers, midwives, health visitors and breastfeeding counsellors as to how exactly services could be improved. Access to evidence-based, family-centred care is vital to address this potentially distressing condition. But are we too quick to jump in with a diagnosis that may ultimately be of no clinical significance? This articles presents two professional perspectives on the issue and highlights the pertinent research available. PMID:25571701

  13. Environmental justice: a criminological perspective

    Lynch, Michael J.; Stretesky, Paul B.; Long, Michael A.

    2015-08-01

    This article examines studies related to environmental justice in the criminological literature and from a criminological perspective. Criminologists have long been concerned with injustices in the criminal justice system related to the enforcement of criminal law. In the 1990s, following the emergence of green criminology, a handful of criminologists have drawn attention to environmental justice as an extension of more traditional criminological studies of justice and injustice. Relevant criminological studies of environmental justice are reviewed, and suggestions for future environmental justice research are offered.

  14. Macroevolutionary perspectives to environmental change.

    PubMed

    Condamine, Fabien L; Rolland, Jonathan; Morlon, Hélène

    2013-05-01

    Predicting how biodiversity will be affected and will respond to human-induced environmental changes is one of the most critical challenges facing ecologists today. Here, we put current environmental changes and their effects on biodiversity in a macroevolutionary perspective. We build on research in palaeontology and recent developments in phylogenetic approaches to ask how macroevolution can help us understand how environmental changes have affected biodiversity in the past, and how they will affect biodiversity in the future. More and more paleontological and phylogenetic data are accumulated, and we argue that much of the potential these data have for understanding environmental changes remains to be explored.

    The user is often the most overlooked component of control system design. At Jefferson Lab the control system is almost entirely digital in nature, with little feedback except that which is deliberately designed into the control system. In the complex control room environment a good design can enhance the user's abilities to preform good science. A bad design can leave the user frustrated and contribute significantly to down time, when science is not being done. Key points of use and design from the user's perspective are discussed, along with some techniques which have been adopted at Jefferson Lab to improve the user experience and produce better, more usable software.

    PubMed

    Cardwell, Michael S

    2012-10-01

    Pregnancy sickness is a universal phenomenon, affecting 70% to 85% of all pregnant women. The primary symptoms of pregnancy sickness are nausea, vomiting, and food aversions. In the past, pregnancy sickness was attributed to psychological disturbances of the pregnant woman. However, recent evolutionary psychological and biopsychological studies have reconsidered pregnancy sickness as an embryo-protective mechanism, an evolutionary adaptation to protect the embryo from phytotoxins and other environmental hazards. The biopsychological perspective of pregnancy sickness as an embryo-protective mechanism is presented. PMID:23112071

  1. Quantum Decoherence: A Logical Perspective

    NASA Astrophysics Data System (ADS)

    Fortin, Sebastian; Vanni, Leonardo

    2014-12-01

    The so-called classical limit of quantum mechanics is generally studied in terms of the decoherence of the state operator that characterizes a system. This is not the only possible approach to decoherence. In previous works we have presented the possibility of studying the classical limit in terms of the decoherence of relevant observables of the system. On the basis of this approach, in this paper we introduce the classical limit from a logical perspective, by studying the way in which the logical structure of quantum properties corresponding to relevant observables acquires Boolean characteristics.

    Over the past 10 years I have been using socio-cultural theoretical perspectives to understand how people learn physics in a highly interactive, inquiry-based physics course such as Physics and Everyday Thinking [1]. As a result of using various perspectives (e.g. Distributed Cognition and Vygotsky's Theory of Concept Formation), my understanding of how these perspectives can be useful for investigating students' learning processes has changed. In this paper, I illustrate changes in my thinking about the role of socio-cultural perspectives in understanding physics learning and describe elements of my thinking that have remained fairly stable. Finally, I will discuss pitfalls in the use of certain perspectives and discuss areas that need attention in theoretical development for PER.

    2016-02-01

    The success of a new technology depends on how well it is accepted by its intended users. Many technologies face the problem of low adoption rate, despite the benefits. An understanding of what makes people accept or reject a new technology can help speed up the adoption rate. This paper presents a framework for technology adoption based on an interactive perspective, resulting from a literature study on technology adoption. In studying technology adoption, it is necessary to consider the interactions among elements involved in the system, for these interactions may generate new characteristics or new relationships. The interactions among elements in a system adoption have not received sufficient consideration in previous studies of technology adoption. Based on the proposed interaction perspective, technology adoption is elaborated by examining interactions among the individual (i.e. the user or prospective user), the technology, the task and the environment. The framework is formulated by adopting several theories, including Perceived Characteristics of Innovating, Diffusion of Innovation Theory, Technology Acceptance Model, Task-Technology Fit and usability theory. The proposed framework is illustrated in the context of mobile banking adoption. It is aimed to offer a better understanding of determinants of technology adoption in various contexts, including technology in manufacturing systems.

    2014-01-01

    Given that a new wave of biosimilar insulins will likely enter the market in coming years, it is important to understand patient perspectives on these biosimilars. A survey (N = 3214) conducted by the market research company dQ&A, which maintains a 10 000-patient panel of people with type 1 or type 2 diabetes in roughly equal measure, investigated these perspectives. The survey asked whether patients would switch to a hypothetical less expensive biosimilar insulin that was approved by their provider. Approximately 66% of respondents reported that they would "definitely" or "likely" use a biosimilar insulin, while 17% reported that they were "unlikely" to use or would "definitely not use" such a product. Type 2 diabetes patients demonstrated slightly more willingness to use biosimilars than type 1 diabetes patients. Common patient concerns included whether biosimilars would be as effective as reference products (~650 respondents), whether side effect profiles would deviate from those of reference products (~220 respondents), and the design of the delivery device (~50 respondents). While cost savings associated with biosimilar insulins could increase patient uptake, especially among patients without health insurance (some recent estimates suggest that biosimilars will come at a substantial discount), patients may still need assurance that a cheaper price tag is not necessarily associated with substandard quality. Overall, the dQ&A survey indicates that the majority of patients are willing to consider biosimilar insulins, but manufacturers will need to work proactively to address and assuage patient concerns regarding efficacy, safety, drug administration, and other factors.

  10. [Growing old differently: Transdisciplinary perspective].

    PubMed

    Zimmermann, H-P

    2015-04-01

    Growing old differently: the phrase is intended to call something other to mind than merely the fact that images and forms of old age and aging have multiplied and diversified to an enormous extent. The suggestion put forward here is that otherness (as opposed to mere differences) should be positively reinforced. In other words, it is not just a matter of noting different forms of old age and aging but more than this, of seeking out opportunities for aging differently. In order to explore this, the article follows an older strand of theory, which has recently come to be frequently quoted in gerontology: the phenomenology of difference as reasoned analytically by Lévinas and Sartre and applied to gerontology by Améry and de Beauvoir. Here, opportunities for aging crucially depend on the way we look at it, how we observe and describe it and not least, how gerontology frames it. A distinction is made between two perspectives and their associated consequences for old age: alienation and alterity. Alienation means looking at old age above all as a disconcerting "other", as a perplexing, problematic deviation from the norm of vitality. Alterity, by contrast, refers to different options for living life in old age: options to be explored and opened up in contradistinction to cultural or academic alienation. Not least, the article appeals for diversity in scholarly approaches and for cross-disciplinary perspectives. PMID:25801518

    PubMed

    Anson, Eric; Jeka, John

    2015-01-01

    Much is known about age-related anatomical changes in the vestibular system. Knowledge regarding how vestibular anatomical changes impact behavior for older adults continues to grow, in line with advancements in diagnostic testing. However, despite advancements in clinical diagnostics, much remains unknown about the functional impact that an aging vestibular system has on daily life activities such as standing and walking. Modern diagnostic tests are very good at characterizing neural activity of the isolated vestibular system, but the tests themselves are artificial and do not reflect the multisensory aspects of natural human behavior. Also, the majority of clinical diagnostic tests are passively applied because active behavior can enhance performance. In this perspective paper, we review anatomical and behavioral changes associated with an aging vestibular system and highlight several areas where a more functionally relevant perspective can be taken. For postural control, a multisensory perturbation approach could be used to bring balance rehabilitation into the arena of precision medicine. For walking and complex gaze stability, this may result in less physiologically specific impairments, but the trade-off would be a greater understanding of how the aging vestibular system truly impacts the daily life of older adults.

    Blustein, David L.; Olle, Chad; Connors-Kellgren, Alice; Diamonti, A. J.

    2016-01-01

    This contribution, which serves as the lead article for the Research Topic entitled “From Meaning of Working to Meaningful Lives: The Challenges of Expanding Decent Work,” explores current challenges in the development and operationalization of decent work. Based on an initiative from the International Labor Organization [ILO] (1999) decent work represents an aspirational statement about the quality of work that should be available to all people who seek to work around the globe. Within recent years, several critiques have been raised about decent work from various disciplines, highlighting concerns about a retreat from the social justice ethos that had initially defined the concept. In addition, other scholars have observed that decent work has not included a focus on the role of meaning and purpose at work. To address these concerns, we propose that a psychological perspective can help to revitalize the decent work agenda by infusing a more specific focus on individual experiences and by reconnecting decent work to its social justice origins. As an illustration of the advantages of a psychological perspective, we explore the rise of precarious work and also connect the decent work agenda to the Psychology-of-Working Framework and Theory (Blustein, 2006; Duffy et al., 2016).

  18. Anxiety impairs spontaneous perspective calculation: Evidence from a level-1 visual perspective-taking task.

    PubMed

    Todd, Andrew R; Simpson, Austin J

    2016-11-01

    Reasoning about other people's mental states is central to social life. Yet, even neuro-typical adults sometimes have perspective-taking difficulties, particularly when another's perspective conflicts with their own. In two experiments, we examined the cognitive mechanisms underlying an affective factor known to hinder perspective taking in adults: anxiety. Using a level-1 visual perspective-taking task, we found that incidentally experiencing anxiety, relative to neutral feelings and anger, impaired the spontaneous calculation of what another social agent can see. Feeling anxious did not, however, impede perspective calculation with a non-social entity, suggesting that anxiety's disruptive effects may be particularly pronounced for social aspects of cognition. These findings help elucidate the mechanisms underlying the effects of incidental emotions on perspective taking and inform debates about "implicit" forms of mentalizing. PMID:27522111

The potential beneficial outcomes from SynBio in the context of medicine are substantial; however it is not presently possible to predict precise outcomes due to the nascent state of the field. Potential negative outcomes from SynBio also exist, including iatrogenesis and bioterrorism; however it is not yet possible to quantify these risks. I argue that the application of a 'precautionary' approach to SynBio is ethically fraught, as is the notion that SynBio-associated knowledge ought to be restricted. I conclude that utilitarians ought to support a broadly laissez-faire stance in respect of SynBio. PMID:24010857

  1. Cell membranes: A subjective perspective.

    PubMed

    Simons, Kai

    2016-10-01

    Cell membranes have developed a tremendous complexity of lipids and proteins geared to perform the functions cells require. The lipids have for long remained in the background and are now regaining their role as important building blocks of cells. Their main function is to form the matrix of our cell membranes where they support a variety of functions essential for life. This 2-dimensional fluid matrix has evolved unexpected material properties that involve both lipid-lipid and lipid-protein interactions. This perspective is a short summary of the challenges that this field faces and discusses potential ways and means for coming to grips with the properties of this incredible fluid. This article is part of a Special Issue entitled: Biosimulations edited by Ilpo Vattulainen and Tomasz Róg. PMID:26827711

  2. Sparsity and the Bayesian perspective

    Sparsity has recently been introduced in cosmology for weak-lensing and cosmic microwave background (CMB) data analysis for different applications such as denoising, component separation, or inpainting (i.e., filling the missing data or the mask). Although it gives very nice numerical results, CMB sparse inpainting has been severely criticized by top researchers in cosmology using arguments derived from a Bayesian perspective. In an attempt to understand their point of view, we realize that interpreting a regularization penalty term as a prior in a Bayesian framework can lead to erroneous conclusions. This paper is by no means against the Bayesian approach, which has proven to be very useful for many applications, but warns against a Bayesian-only interpretation in data analysis, which can be misleading in some cases.

    Aspirin is one of the oldest medicines. Due to its wide range usage in different fields of medicine, we aimed to present the history, effects and different uses of aspirin in this review. Furthermore, recent patents of novel pharmaceutical interventions in the field of acetylsalicylic acid, expanding treatment options are presented. Literature search was performed in order to reach data and present information about aspirin from a historical perspective. Since its first use as a pain killer, aspirin has found a broad range of use in general medicine, cardiovascular medicine, neurology, obstetrics and gynecology, dentistry, gastroenterology, oncology with its different effects. Aspirin, a painkilling gift of history to mankind, with a history dating back to BC and various healing effects, promises to be of greater use in different fields of medicine with the light of recent studies, inspiring more research and gaining more popularity.

    2011-01-01

    Although siblings are a fixture of family life, research on sibling relationships lags behind that on other family relationships. To stimulate interest in sibling research and to serve as a guide for future investigations by family scholars, we review four theoretical psychologically oriented perspectives—(a) psychoanalytic-evolutionary, (b) social psychological, (c) social learning, and (d) family-ecological systems—that can inform research on sibling relationships, including perspectives on the nature and influences on developmental, individual, and group differences in sibling relationships. Given that most research on siblings has focused on childhood and adolescence, our review highlights these developmental periods, but we also incorporate the limited research on adult sibling relationships, including in formulating suggestions for future research on this fundamental family relationship.

    PubMed

    Kafatos, Menas C; Chevalier, Gaétan; Chopra, Deepak; Hubacher, John; Kak, Subhash; Theise, Neil D

    2015-11-01

    This article briefly reviews the biofield hypothesis and its scientific literature. Evidence for the existence of the biofield now exists, and current theoretical foundations are now being developed. A review of the biofield and related topics from the perspective of physical science is needed to identify a common body of knowledge and evaluate possible underlying principles of origin of the biofield. The properties of such a field could be based on electromagnetic fields, coherent states, biophotons, quantum and quantum-like processes, and ultimately the quantum vacuum. Given this evidence, we intend to inquire and discuss how the existence of the biofield challenges reductionist approaches and presents its own challenges regarding the origin and source of the biofield, the specific evidence for its existence, its relation to biology, and last but not least, how it may inform an integrated understanding of consciousness and the living universe.

  6. Nursing perspectives for intensive care.

    PubMed

    Woodrow, P

    1997-06-01

    Within health care, market forces increasingly determine what services have economic value. For nursing to survive this economic onslaught, nurses must clarify their values and roles. While nurses working in intensive care develop useful technical skills and normally work within a constructive multi-disciplinary team framework, they have a potentially unique contribution to care, focusing on the patient as a whole person rather than intervening to solve a problem. The need for both physiological and psychological care creates a need for holistic values, best achieved through humanistic perspectives. Humanistic nursing places patients as people at the centre of nursing care, as illustrated by the limitations of reality orientation compared with the potentials of validation therapy. Intensive care nurses asserting and developing such patient-centred roles offer a valuable way forward for nursing to develop into the 21st century. PMID:9287577

  7. A coastal perspective on security.

    PubMed

    Emerson, Steven D; Nadeau, John

    2003-11-14

    This paper examines security issues from the unique perspective of our nation's coastlines and associated infrastructure. It surveys ongoing efforts to secure offshore shipping lanes, as well as the transportation systems and huge capital investments on the narrow strip of land intersecting with coastal waters. The paper recounts the extraordinary demands recently placed on the Coast Guard, port authorities and other agencies charged with offshore security. New federal requirements such as port assessments continue to be mandated, while solutions to finding are still unfolding. An up-to-date summary of maritime security functions is provided. Those requirements are compared and contrasted with security guidelines and regulatory demands placed upon mobile and fixed assets of the Chemical Process Industry (CPI) in coastal environs. These span the gamut from recommendations by industry groups and professional organizations, to federal and state requirements, to insurance demands, to general duty obligations. PMID:14602395

    Seven authors bring a variety of perspectives to the subject of minerals availability. In the domestic area, an overview of the US strategic mineral situation is followed by a discussion of changes in one state's mineral policy decisions over a 200-year period. Later chapters describe the potential of Alaska's mineral resources, with a focus on the immediate need for a thorough inventory of this vast area, and the nature and sources of mineral information available to Canadian policymakers as useful models in making inventories. In the international area, there is a discussion of the key role of South Africa in the world mineral picture and the strategic importance to the Soviet Union of the mineral wealth of Afghanistan. The volume concludes with a review of the history of US mineral policies. Separate abstracts were prepared for the seven chapters selected for the Energy Data Base (EDB) and Energy Abstracts for Policy Analysis (EAPA).

  9. Perspectives on anechoic chamber qualification

    Cunefare, Kenneth A.; Biesel, Van B.

    2002-11-01

    The qualification of a new anechoic chamber requires demonstration that the chamber produces a free-field environment within some tolerance bounds and over some acceptable volume. At the most basic level, qualification requires measurement of sound levels at increasing distances from a test source, and then comparing the levels to a theoretical free-field decay. While simple in concept, the actual performance of a qualification test is problematic in implementation, with troublesome issues relevant to the nature of the sound source, test signal (broadband or pure tone), spatial resolution of measurements (e.g., measurements at discrete locations or spatially continuous), and comparison of the data to a theoretical decay. This presentation will provide a brief historical perspective on chamber qualification and review current practice. It will demonstrate the inadequacy of broadband noise and widely spaced discrete measurements for qualification purposes. It will demonstrate that pure tone signals and spatially continuous measurements provide a rigorous test of a chambers performance.

    We present a brief review of Cosmological Inflation from the personal perspective of the speaker who almost 30 years ago proposed a way of resolving the problem of Cosmological Horizon by employing certain notions and developments from the field of High Energy Physics. Along with a brief introduction of the Horizon and Flatness problems of standard cosmology, this lecture concentrates on personal reminiscing of the notions and ideas that prevailed and influenced the author's thinking at the time. The lecture then touches upon some more recent developments related to the subject including exact solutions to conformal gravity that provide a first principles emergence of a characteristic acceleration in the universe and concludes with some personal views concerning the direction that the cosmology field has taken in the past couple of decades and certain speculations some notions that may indicate future directions of research.

  11. Perspectives on sustainable waste management.

    PubMed

    Castaldi, Marco J

    2014-01-01

    Sustainable waste management is a goal that all societies must strive to maintain. Currently nearly 80% of global wastes are sent to landfill, with a significant amount lacking proper design or containment. The increased attention to environmental impacts of human activities and the increasing demand for energy and materials have resulted in a new perspective on waste streams. Use of waste streams for energy and materials recovery is becoming more prevalent, especially in developed regions of the world, such as Europe, the United States, and Japan. Although currently these efforts have a small impact on waste disposal, use of waste streams to extract value very likely will increase as society becomes more aware of the options available. This review presents an overview of waste management with a focus on following an expanded waste hierarchy to extract value specifically from municipal solid waste streams. PMID:24910921

    2012-01-01

    Historical collapse of ancient states or civilizations has raised new awareness about its possible relevance to current issues of sustainability, in the context of global change. This Special Feature examines 12 case studies of societies under stress, of which seven suffered severe transformation. Outcomes were complex and unpredictable. Five others overcame breakdown through environmental, political, or socio-cultural resilience, which deserves as much attention as the identification of stressors. Response to environmental crises of the last millennium varied greatly according to place and time but drew from traditional knowledge to evaluate new information or experiment with increasing flexibility, even if modernization or intensification were decentralized and protracted. Longer-term diachronic experience offers insight into how societies have dealt with acute stress, a more instructive perspective for the future than is offered by apocalyptic scenarios.

    2011-01-01

    Memory is prone to distortions that can have serious consequences in everyday life. Here we integrate emerging evidence that several types of memory distortions – imagination inflation, gist-based and associative memory errors, and post-event misinformation – reflect adaptive cognitive processes that contribute to the efficient functioning of memory, but produce distortions as a consequence of doing so. We consider recent cognitive and neuroimaging studies that link these distortions with adaptive processes, including simulation of future events, semantic and contextual encoding, creativity, and memory updating. We also discuss new evidence concerning factors that can influence the occurrence of memory distortions, such as sleep and retrieval conditions, as well as conceptual issues related to the development of an adaptive perspective.

    2016-01-01

    Familial Mediterranean fever (FMF) is the most frequent monogenic autoinflammatory disease, and it is characterized by recurrent attacks of fever and polyserositis. The disease is associated with mutations in the MEFV gene encoding pyrin, which causes exaggerated inflammatory response through uncontrolled production of interleukin 1. The major long-term complication of FMF is amyloidosis. Colchicine remains the principle therapy, and the aim of treatment is to prevent acute attacks and the consequences of chronic inflammation. With the evolution in the concepts about the etiopathogenesis and genetics of the disease, we have understood that FMF is more complicated than an ordinary autosomal recessive monogenic disorder. Recently, recommendation sets have been generated for interpretation of genetic testing and genetic diagnosis of FMF. Here, we have reviewed the current perspectives in FMF in light of recent recommendations. PMID:27051312

    2013-01-01

    In the 2000s, online games became popular, while studies of Internet gaming addiction emerged, outlining the negative consequences of excessive gaming, its prevalence, and associated risk factors. The establishment of specialized treatment centers in South-East Asia, the US, and Europe reflects the growing need for professional help. It is argued that only by understanding the appeal of Internet gaming, its context, and neurobiologic correlates can the phenomenon of Internet gaming addiction be understood comprehensively. The aim of this review is to provide an insight into current perspectives on Internet gaming addiction using a holistic approach, taking into consideration the mass appeal of online games, the context of Internet gaming addiction, and associated neuroimaging findings, as well as the current diagnostic framework adopted by the American Psychiatric Association. The cited research indicates that the individual's context is a significant factor that marks the dividing line between excessive gaming and gaming addiction, and the game context can gain particular importance for players, depending on their life situation and gaming preferences. Moreover, the cultural context is significant because it embeds the gamer in a community with shared beliefs and practices, endowing their gaming with particular meaning. The cited neuroimaging studies indicate that Internet gaming addiction shares similarities with other addictions, including substance dependence, at the molecular, neurocircuitry, and behavioral levels. The findings provide support for the current perspective of understanding Internet gaming addiction from a disease framework. The benefits of an Internet gaming addiction diagnosis include reliability across research, destigmatization of individuals, development of efficacious treatments, and the creation of an incentive for public health care and insurance providers. The holistic approach adopted here not only highlights empirical research that

    Context: National efforts are underway to classify a minimum set of public health services that all jurisdictions throughout the United States should provide regardless of location. Such a set of basic programs would be supported by crosscutting services, known as the “foundational capabilities” (FCs). These FCs are assessment services, preparedness and disaster response, policy development, communications, community partnership, and organizational support activities. Objective: To ascertain familiarity with the term and concept of FCs and gather related perspectives from state and local public health practitioners. Design: In fall 2013, we interviewed 50 leaders from state and local health departments. We asked about familiarity with the term “foundational capabilities,” as well as the broader concept of FCs. We attempted to triangulate the utility of the FC concept by asking respondents about priority programs and services, about perceived unique contributions made by public health, and about prevalence and funding for the FCs. Setting: Telephone-based interviews. Participants: Fifty leaders of state and local health departments. Main Outcome Measures: Practitioner familiarity with and perspectives on the FCs, information about current funding streams for public health, and the likelihood of creating nationwide FCs that would be recognized and accepted by all jurisdictions. Results: Slightly more than half of the leaders interviewed said that they were familiar with the concept of FCs. In most cases, health departments had all of the capabilities to some degree, although operationalization varied. Few indicated that current funding levels were sufficient to support implementing a minimum level of FCs nationally. Conclusions: Respondents were not able to articulate the current or optimal levels of services for the various capabilities, nor the costs associated with them. Further research is needed to understand the role of FCs as part of the foundational

    Given that a new wave of biosimilar insulins will likely enter the market in coming years, it is important to understand patient perspectives on these biosimilars. A survey (N = 3214) conducted by the market research company dQ&A, which maintains a 10 000-patient panel of people with type 1 or type 2 diabetes in roughly equal measure, investigated these perspectives. The survey asked whether patients would switch to a hypothetical less expensive biosimilar insulin that was approved by their provider. Approximately 66% of respondents reported that they would “definitely” or “likely” use a biosimilar insulin, while 17% reported that they were “unlikely” to use or would “definitely not use” such a product. Type 2 diabetes patients demonstrated slightly more willingness to use biosimilars than type 1 diabetes patients. Common patient concerns included whether biosimilars would be as effective as reference products (~650 respondents), whether side effect profiles would deviate from those of reference products (~220 respondents), and the design of the delivery device (~50 respondents). While cost savings associated with biosimilar insulins could increase patient uptake, especially among patients without health insurance (some recent estimates suggest that biosimilars will come at a substantial discount), patients may still need assurance that a cheaper price tag is not necessarily associated with substandard quality. Overall, the dQ&A survey indicates that the majority of patients are willing to consider biosimilar insulins, but manufacturers will need to work proactively to address and assuage patient concerns regarding efficacy, safety, drug administration, and other factors.
