  1. 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

  3. 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

    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

    La coxalgie entraine des destructions ostéo-cartilagineuses de l'articulation de la hanche, ces lésions sont responsables de douleurs intenses provoquant des gènes fonctionnelles et des limitations dans la vie quotidienne. Leur traitement chirurgical est encore mal codifié. Notre objectif est de montrer à travers cette étude l'intérêt de l'arthroplastie totale de hanche associée à la chimiothérapie antituberculeuse pour l'amélioration de la qualité de vie des patients. Nous rapportons une étude rétrospective portant sur 10 cas de prothèses totales de hanche posées sur séquelles de coxalgie au service de traumatologie-orthopédie du centre hospitalier universitaire Rabat de 2002 à 2011. L’âge moyen de nos patients est de 38 ans. La découverte de la coxalgie s'est faite dans des circonstances différentes en fonction des patients. La voie d'abord que nous avons utilisé est exclusivement postéro-externe de Moore. Les prothèses posées ont toute été cimentées. Quatre patients ont nécessité la reconstruction du cotyle. La biopsie peropératoire est positive chez un patient, négative chez les neuf restants. Tous les patients ont été mis sous traitement antituberculeux. Aucune récidive n'a été notée après un recul minimal de 3 ans. Les résultats selon la cotation de Merle d'Aubigné sont jugés bons. En cas de destruction osseuse avancée avec retentissement fonctionnel très mal supporté chez le sujet d’âge mûr, l'arthroplastie totale demeure le traitement de choix des séquelles de coxalgie sous couverture systématique d'une chimiothérapie antituberculeuse efficace.

    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

  8. Modelisation de l'erosion et des sources de pollution dans le bassin versant Iroquois/Blanchette dans un contexte de changements climatiques

    Coulibaly, Issa

    Principale source d'approvisionnement en eau potable de la municipalite d'Edmundston, le bassin versant Iroquois/Blanchette est un enjeu capital pour cette derniere, d'ou les efforts constants deployes pour assurer la preservation de la qualite de son eau. A cet effet, plusieurs etudes y ont ete menees. Les plus recentes ont identifie des menaces de pollution de diverses origines dont celles associees aux changements climatiques (e.g. Maaref 2012). Au regard des impacts des modifications climatiques annonces a l'echelle du Nouveau-Brunswick, le bassin versant Iroquois/Blanchette pourrait etre fortement affecte, et cela de diverses facons. Plusieurs scenarios d'impacts sont envisageables, notamment les risques d'inondation, d'erosion et de pollution a travers une augmentation des precipitations et du ruissellement. Face a toutes ces menaces eventuelles, l'objectif de cette etude est d'evaluer les impacts potentiels des changements climatiques sur les risques d'erosion et de pollution a l'echelle du bassin versant Iroquois/Blanchette. Pour ce faire, la version canadienne de l'equation universelle revisee des pertes en sol RUSLE-CAN et le modele hydrologique SWAT ( Soil and Water Assessment Tool) ont ete utilises pour modeliser les risques d'erosion et de pollution au niveau dans la zone d'etude. Les donnees utilisees pour realiser ce travail proviennent de sources diverses et variees (teledetections, pedologiques, topographiques, meteorologiques, etc.). Les simulations ont ete realisees en deux etapes distinctes, d'abord dans les conditions actuelles ou l'annee 2013 a ete choisie comme annee de reference, ensuite en 2025 et 2050. Les resultats obtenus montrent une tendance a la hausse de la production de sediments dans les prochaines annees. La production maximale annuelle augmente de 8,34 % et 8,08 % respectivement en 2025 et 2050 selon notre scenario le plus optimiste, et de 29,99 % en 2025 et 29,72 % en 2050 selon le scenario le plus pessimiste par rapport a celle

    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

    L'arthroplastie totale au cours des séquelles d'infection ostéo-articulaire a été destinée surtout pour la hanche et le genou. Cependant, peu de travaux ont étaient consacrée pour l'articulation du coude. Nous rapportons le cas d'une patiente, âgée de 26 ans, ayant présentée dans l'enfance une ostéoarthrite du coude traitée traditionnellement, mais qui a développé progressivement une instabilité sévère du coude. Après l'implantation d'une prothèse semi-contrainte de Coonrad-Morrey non cimentée, le résultat est très satisfaisant jusqu’à deux ans de recul, avec un gain de la mobilité en flexion de 110 degrés et en extension de 5 degrés, l'index de performance pour le coude selon la Mayo Clinic de 80/100. Nous n'avons pas de complication à déplorer. PMID:22355439

    L'accouchement d'un fœtus macrosome est un accouchement à haut risque de complications maternofoetales. La dystocie des épaules reste la complication fœtale la plus redoutée, amenant au recours, parfois démesuré, à la césarienne. L'objectif de ce travail est d'évaluer l'intérêt de cette césarienne préventive. Il s'agit d'une étude rétrospective à propos de 400 accouchements de fœtus macrosomes survenus entre Février 2010 et Décembre 2012. Nous avons aussi identifié les cas de nouveau-nés ayant eu une dystocie des épaules pendant l'année 2012 ainsi que leur poids de naissance respectifs. Les fœtus macrosomes ont pesé entre 4000g et 4500g dans 86,25% des cas et entre 4500 et 5000 dans 12,25% des cas. L'accouchement était par voie basse dans 68% des cas. Parmi les 400 accouchements de macrosomes, 9 cas de dystocie des épaules ont été enregistrés (2,25%). Tous ces cas sont survenus lors d'accouchements par voie basse. Le risque de dystocie des épaules lors d'un accouchement par voie basse a augmenté de façon significative avec l'augmentation du poids à la naissance (p<10-4). Le risque d'élongation du plexus brachial était de 11 pour mille accouchements de macrosomes par voie basse. Ce risque n'était pas corrélé au poids de naissance (p=0,38). Le risque de séquelles post-traumatiques était de 0,71%. La dystocie des épaules a concerné un fœtus macrosome dans 58 % des cas. La dystocie des épaules n'est pas une complication exclusivement associée à la macrosomie. Le dépistage des accouchements à risque et le renforcement de la formation des obstétriciens sur les manœuvres à réaliser en cas de dystocie des épaules semblent être les meilleurs moyens pour éviter ses complications.

    2014-06-01

    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.

    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.

    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.

  8. 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

    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.

  13. Oahu: perspective from space

    USGS Publications Warehouse

    Johnson, Gary E.

    1982-01-01

    Satellite remote sensing provides us with a unique perspective from space. This perspective is synoptic in nature and provides regional views of most of the land areas of the earth. The orbital characteristics of the Landsat system are such that repetitive imagery of the same area may be obtained. Because of the permanent nature of the imagery, it may be retrieved for comparative analysis at any time. Comparisons of this image of Oahu with maps of the island (for example, the Oahu, Hawaii, 1:250,000-scale topographic map) will enable the reader to readily identify the place names discussed in this article and permit a more detailed interpretation of the image.

  18. The technician's perspective

    SciTech Connect

    Rechlin, M. )

    1993-06-01

    This article is a practical approach for Third World education from a technician's perspective on the problems of international development. Forestry technician schools should become involved in international forestry development. The major example presented in this paper is the Nepal Institute of Forestry. Historically, professional foresters in Nepal were interested in managing Nepal's forests for timber and pulpwood while villagers were interested in fuelwoods and fodder. To effectively train foresters for new jobs in which they provide advice to villagers who make forest management decisions, both the cirriculum and resulting education have to be very different. But in addition teachers have to be reeducated and textbooks, lab manuals, and field exercises must be changed. Projects such as forestry management in Nepal could prove more effective if they combined research skills and problem-solving approaches of a university with the technical perspective and applied orientation of a forestry technician school.

  4. 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.

    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.

  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.

    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!

    This perspective will overview an emerging paradigm for self-organized soft materials, geometrically frustrated assemblies, where interactions between self-assembling elements (e.g., particles, macromolecules, proteins) favor local packing motifs that are incompatible with uniform global order in the assembly. This classification applies to a broad range of material assemblies including self-twisting protein filament bundles, amyloid fibers, chiral smectics and membranes, particle-coated droplets, curved protein shells, and phase-separated lipid vesicles. In assemblies, geometric frustration leads to a host of anomalous structural and thermodynamic properties, including heterogeneous and internally stressed equilibrium structures, self-limiting assembly, and topological defects in the equilibrium assembly structures. The purpose of this perspective is to (1) highlight the unifying principles and consequences of geometric frustration in soft matter assemblies; (2) classify the known distinct modes of frustration and review corresponding experimental examples; and (3) describe outstanding questions not yet addressed about the unique properties and behaviors of this broad class of systems.

  1. Auditory perspective taking.

    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.

  2. Perspectives in numerical astrophysics:

    NASA Astrophysics Data System (ADS)

    Reverdy, V.

    2016-12-01

    In this discussion paper, we investigate the current and future status of numerical astrophysics and highlight key questions concerning the transition to the exascale era. We first discuss the fact that one of the main motivation behind high performance simulations should not be the reproduction of observational or experimental data, but the understanding of the emergence of complexity from fundamental laws. This motivation is put into perspective regarding the quest for more computational power and we argue that extra computational resources can be used to gain in abstraction. Then, the readiness level of present-day simulation codes in regard to upcoming exascale architecture is examined and two major challenges are raised concerning both the central role of data movement for performances and the growing complexity of codes. Software architecture is finally presented as a key component to make the most of upcoming architectures while solving original physics problems.

  3. Antarctica: little paying perspectives

    SciTech Connect

    Ivanhoe, L.F.

    The continent of Antarctica has a surface of 14,200,000 sq km. It rests upon one of the deeper epicontinental platforms of the world, which descends steeply to the oceanic depths. The 200-m isobath is almost in its totality inside of the main ice zone. More than 95% of the continent itself is found under a layer of terrestrial ice composed of ca. 3,000,000 cu km of ice, with an average thickness of 2000 m. The ice and sea impede the access to the continent, and cyclonic storms surround the Antarctica in an endless sequence that moves from west to east. Almost all Antarctica geology is under ice, and only the highest places of mountains outcrop. The geologic structure is composed of 6 tectonic units. Antarctica has mineral resources, but the obstacles encountered in personnel and material movement make the Antarctica petroleum perspective very poor, since the recovery cost goes beyond the present selling price.

    Are you familiar with the famed Generation Y, or "Gen Yers?" Generation Y is projected to be 47 percent of the workforce by 2014. 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. This knowledge capture (KC) event is that presentation.

  5. Perspective: reverse evolution.

    PubMed

    Teotónio, H; Rose, M R

    2001-04-01

    For some time, the reversibility of evolution was primarily discussed in terms of comparative patterns. Only recently has this problem been studied using experimental evolution over shorter evolutionary time frames. This has raised questions of definition, experimental procedure, and the hypotheses being tested. Experimental evolution has provided evidence for multiple population genetic mechanisms in reverse evolution, including pleiotropy and mutation accumulation. It has also pointed to genetic factors that might prevent reverse evolution, such as a lack of genetic variability, epistasis, and differential genotype-by-environment interactions. The main focus of this perspective is on laboratory studies and their relevance to the genetics of reverse evolution. We discuss reverse evolution experiments with Drosophila, bacterial, and viral populations. Field studies of the reverse evolution of melanism in the peppered moth are also reviewed.

  6. Diabetes: An Investor's Perspective

    PubMed Central

    Harris, Bernard

    2008-01-01

    Total health care expenditure in 2006 was $2.1 trillion. This figure is estimated to double within the next few years as the cost of treating diabetes and other chronic conditions continues to rise. Moreover, the baby boomer demographic is anticipated to place an enormous burden on the health care system and employer-based health insurance premiums were increased at rates as high as 10% per year in 2006. The quest to address these challenges has also created opportunities for investment, particularly in the fields of telemedicine, health care information technology, and medical technology. The author shares his business perspective, informed by years of experience as a physician and astronaut at NASA, and describes new applications of exciting technologies that deliver effective and efficient health care to diabetes patients, no matter where they may be.

  12. Perspective View, Garlock Fault

    NASA Technical Reports Server (NTRS)

    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

    Medication reviews have the potential to lower the incidence of prescribing errors. To benefit from a medication review, the prescriber must adhere to medication counselling. Adherence rates vary from 39 to 100%. The aim of this study was to examine counselling-naive hospital physicians' perspectives and demands to medication counselling as well as study factors that might increase adherence to the counselling. The study was conducted as a questionnaire survey among physicians at Aarhus University Hospital, Denmark. The questionnaire was developed based on focus group interviews and literature search, and was pilot-tested among 30 physicians before being sent to 669 physicians. The questionnaire consisted of 35 items divided into four categories: attitudes (19 items), behaviours (3 items), assessment (8 items) and demographics (5 items). The response rate was 60% (400/669). Respondents were employed at psychiatric, medical or surgical departments. Eighty-five per cent of respondents agreed that patients would benefit of an extra medication review, and 72% agreed that there was a need for external medication counselling. The most important factor that could increase adherence was the clinical relevance of the counselling as 78% rated it of major importance. The most favoured method for receiving counselling was via the electronic patient record.

  14. 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

  15. A Global Perspective

    PubMed Central

    Harrison, Mark

    2015-01-01

    Summary The emergence of global history has been one of the more notable features of academic history over the past three decades. Although historians of disease were among the pioneers of one of its earlier incarnations—world history—the recent “global turn” has made relatively little impact on histories of health, disease, and medicine. Most continue to be framed by familiar entities such as the colony or nation-state or are confined to particular medical “traditions.” This article aims to show what can be gained from taking a broader perspective. Its purpose is not to replace other ways of seeing or to write a new “grand narrative” but to show how transnational and transimperial approaches are vital to understanding some of the key issues with which historians of health, disease, and medicine are concerned. Moving on from an analysis of earlier periods of integration, the article offers some reflections on our own era of globalization and on the emerging field of global health. PMID:26725408

  16. New perspectives in ecotoxicology

    NASA Astrophysics Data System (ADS)

    Levin, Simon A.; Kimball, Kenneth D.; McDowell, William H.; Kimball, Sarah F.

    1984-09-01

    The task of regulating potentially harmful chemicals in the environment is presently hindered by the lack of appropriate concepts and methods for evaluating the effects of anthropogenic chemicals on ecosystems. Toxicity tests at the molecular and physiological levels have been used successfully as indicators of adverse effects on test organisms and have been extrapolated to humans to establish a basis for risk assessment. However, laboratory measurements of effects upon individuals do not translate readily into potential effects upon natural populations, in part because natural populations interact with other populations and with the physical environment. Even more difficult to assess are the deleterious impacts of anthropogenic chemicals on ecosystems, because of effects on species interactions, diversity, nutrient cycling, productivity, climatic changes, and other processes. Effects on ecosystems resulting from chemical stresses are outside the realm of classical toxicology, and an ecosystem-level perspective is essential for the consideration of such effects; but the science that deals with ecosystem-level effects, ecotoxicology, is still developing. This article synthesizes the topics discussed at a workshop on ecotoxicology held by the Ecosystems Research Center at Cornell University. Topics covered include: the regulatory framework in which ecotoxicological research must be applied; ecosystem modification of toxicant fate and transport; how ecosystem composition, structure, and function are influenced by chemicals; methods currently available for predicting the effects of chemicals at the ecosystem level; and recommendations on research needs to enhance the state of the science of ecotoxicology.

  17. Perspectives of Nuclear Physics

    The organizers of this meeting have asked me to present perspectives of nuclear physics. This means to identify the areas where nuclear physics will be expanding in the next future. In six chapters a short overview of these areas will be given, where I expect that nuclear physics will develop quite fast: (1) Quantum Chromodynamics and effective field theories in the confinement region. (2) Nuclear structure at the limits. (3) High energy heavy ion collisions. (4) Nuclear astrophysics. (5) Neutrino physics. (6) Test of physics beyond the standard model by rare processes. After a survey over these six points I will pick out a few topics where I will go more in details. There is no time to give for all six points detailed examples. I shall discuss the following examples of the six topics mentionned above: (1) The perturbative chiral quark model and the nucleon Σ-term. (2) VAMPIR (Variation After Mean field Projection In Realistic model spaces and with realistic forces) as an example of the nuclear structure renaissance. (3) Measurement of important astrophysical nuclear reactions in the Gamow peak. (4) The solar neutrino problem. As examples for testing new physics beyond the standard model by rare processes I had prepared to speak about the measurement of the electric neutron dipole moment and of the neutrinoless double beta decay. But the time is limited and so I have to skip these points, although they are extremely interesting.

    LeRouge, Cynthia M; Garfield, Monica J; Hevner, Alan R

    2015-01-01

    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.

    2016-02-01

    Personality psychology has made enormous progresses over the years by accumulating empirical evidence on how patterns of stable individual differences in behaviours can be clustered systematically at different levels of abstraction (i.e. traits and facets) and how they can predict important consequential outcomes. At the same time, functionally orientated researchers have accumulated a vast body of knowledge on environment-behaviour relations and the underlying behavioural principles, that is, abstract descriptions of the way in which behaviour is a function of elements in the past and present environment. We explore a functional perspective on personality that attempts to bridge the two domains and to exploit the best of both worlds. From this functional perspective, personality refers to the impact of the individual on different types of environment-behaviour relations as well as on the way other factors moderate those relations. We discuss the potential of this functional perspective on personality to organise existing scientific knowledge and inspire future research.

  1. Fructose in perspective

    PubMed Central

    2013-01-01

    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. Popular opinion cannot be ignored in this problem and comparing fructose

  2. 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.

    Objectif : Explorer les perspectives des physiothérapeutes ayant participé à un stage clinique à l'étranger dans un pays à revenu faible ou intermédiaire dans le cadre de leur formation en physiothérapie dans un programme d'études canadien afin d'évaluer l'incidence de ce stage sur leur pratique de la physiothérapie au Canada. Méthodes : Cette étude descriptive qualitative s'est faite à partir d'entrevues semi-structurées détaillées. Les données ont été organisées au moyen de Nvivo, tandis qu'un codage inductif et déductif a été utilisé pour analyser les données et élargir les thèmes. Résultats : Les 13 physiothérapeutes exerçant au Canada qui ont été interviewés ont décrit trois compétences renforcées par leur stage: (1) la réflexion critique sur la culture, les valeurs et la pratique; (2) les aptitudes à communiquer et (3) la créativité et la débrouillardise. Il semble que ces compétences se seraient transférées dans la pratique canadienne en améliorant la capacité des participants à offrir des soins axés sur le client, plus précisément grâce à une meilleure compréhension des valeurs et des déterminants sociaux de la santé des clients, quelle que soit la région du Canada ou la clientèle. Conclusions : Pour les étudiants en physiothérapie qui envisagent un stage clinique à l'étranger, les conclusions de l'étude montrent l'incidence que pourrait avoir un tel stage sur la pratique canadienne. Pour les programmes universitaires de physiothérapie, les conclusions de l'étude peuvent orienter les décisions quant à l'ampleur des investissements dans les stages cliniques à l'étranger en tant qu'occasions d'apprentissage destinées à améliorer la pratique au Canada.

  17. Empathy and visual perspective-taking performance.

    PubMed

    Mattan, Bradley D; Rotshtein, Pia; Quinn, Kimberly A

    2016-01-01

    This study examined the extent to which visual perspective-taking performance is modulated by trait-level empathy. Participants completed a third-person visual perspective-taking task in which they judged the perspectives of two simultaneously presented avatars, designated "Self" and "Other." Depending on the trial, these avatars either held the same view (i.e., congruent) or a different view (i.e., incongruent). Analyses focused on the relationship between empathy and two perspective-taking phenomena: Selection between competing perspectives (i.e., perspective-congruence effects) and prioritization of the Self avatar's perspective. Empathy was related to improved overall performance on this task and a reduced cost of selecting between conflicting perspectives (i.e., smaller perspective-congruence effects). This effect was asymmetric, with empathy (i.e., empathic concern) levels predicting reduced interference from a conflicting perspective, especially when adopting the Self (vs. Other) avatar's perspective. Taken together, these results highlight the importance of the self-other distinction and mental flexibility components of empathy.

  18. Perspective taking in older age revisited: a motivational perspective.

    PubMed

    Zhang, Xin; Fung, Helene H; Stanley, Jennifer T; Isaacowitz, Derek M; Ho, Man Yee

    2013-10-01

    How perspective-taking ability changes with age (i.e., whether older adults are better at understanding others' behaviors and intentions and show greater empathy to others or not) is not clear, with prior empirical findings on this phenomenon yielding mixed results. In a series of experiments, we investigated the phenomenon from a motivational perspective. Perceived closeness between participants and the experimenter (Study 1) or the target in an emotion recognition task (Study 2) was manipulated to examine whether the closeness could influence participants' performance in faux pas recognition (Study 1) and emotion recognition (Study 2). It was found that the well-documented negative age effect (i.e., older adults performed worse than younger adults in faux pas and emotion recognition tasks) was only replicated in the control condition for both tasks. When closeness was experimentally increased, older adults enhanced their performance, and they now performed at a comparable level as younger adults. Findings from the 2 experiments suggest that the reported poorer performance of older adults in perspective-taking tasks might be attributable to a lack of motivation instead of ability to perform in laboratory settings. With the presence of strong motivation, older adults have the ability to perform equally well as younger adults.

  19. Industry Perspective on Alopecia Areata.

    PubMed

    Wagner, Amanda T

    2015-11-01

    Recent advances in our understanding of the autoimmune basis of alopecia areata provide an opportunity to create novel effective pharmaceutical interventions. The current lack of approved therapies for alopecia areata presents a high unmet medical need, as well as a potentially attractive market opportunity. From an industry perspective, achieving clinical proof of concept (PoC) gates investments into larger approval studies. Recent investigator-initiated experience suggests that it may be possible to demonstrate rigorous PoC for new therapies in an attractive time frame with relatively fewer patients than were believed necessary in the past. However, the lack of prior regulatory approval precedent for pharmaceuticals to treat alopecia areata poses significant development challenges, and early interaction with the FDA and other stakeholders will be critically important in evaluating the path to approval and reimbursement for new treatments for this indication. This paper presents a brief industry perspective on the potential development of new alopecia areata therapeutics.

This document, with its claim that the Chernobyl accident has already killed several hundred thousand people (the figure of 985,000 is mentioned), was published without peer review and has since been disowned by the New York Academy of Sciences.

  1. Intersectional perspective in elderly care

    PubMed Central

    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

    Cable, Christian; Chong, Tae; Pratt, Daniel D

    2012-06-01

    Just as everyone has a different learning style, teachers too approach the task from different perspectives. There are five basic teaching perspectives or styles: transmission, apprenticeship, developmental, nurturing, and social justice. The acronym BIAS is useful to describe the beliefs, intentions, assessments, and strategies associated with each perspective. The authors present a hypothetical 1-week rotation in plastic and reconstructive surgery in which a student encounters instructors who embody the five basic teaching perspectives. By presenting these perspectives, the authors introduce valuable teaching techniques that can benefit all those charged with the education of learners along the spectrum from premedical to continuing education venues. Educational objectives include the following: (1) explain and illustrate different approaches to effective teaching in plastic surgery; (2) introduce readers to the Teaching Perspectives Inventory as a means of determining their primary teaching style; and (3) argue for a "plurality of the good" in teaching.

    The population health perspective has become increasingly apparent in the medical, public health, and policy literature. This article emphasizes the value of applying the population health perspective and associated frameworks to the rehabilitative sciences and particularly to the field of audiology. Key components of the population health perspective--including the determinants of health, the importance of evidence-based practice, and the value of transdisciplinarity--are used to illustrate the relevance of population health to the field of audiology. Using these key concepts from a population health framework and examples from audiology, the adoption of a population health perspective is proposed.

    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.

    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.

    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.

    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?

    Quorum sensing is the efficient mode of communication in the bacterial world. After a lot of advancements in the classical theory of quorum sensing few basic questions of quorum sensing still remain unanswered. The sufficient progresses in quantum biology demands to explain these questions from the quantum perspective as non trivial quantum effects already have manifested in various biological processes like photosynthesis, magneto-reception etc. Therefore, it's the time to review the bacterial communications from the quantum view point. In this article we carefully accumulate the latest results and arguments to strengthen quantum biology through the addition of quorum sensing mechanism in the light of quantum mechanics.

    2014-12-01

    This research aimed to investigate educators' implicit perspectives on wisdom in order to compare interpersonal and intrapersonal perspectives and to help identify similarities or differences between these two theoretical perspectives. A total of 56 educators in Taiwan were interviewed individually. We utilised the grounded theory method to analyse the qualitative data. Results showed that both interpersonal and intrapersonal perspectives converged on four core components of wisdom: intrapsychic integration, actions in service of problem solving and ideal implementation, positive results and feedback and adjustments. The interpersonal perspective referred to external characteristics, and admiration and influence, whereas the intrapersonal perspective included greater detail about intrapsychic integration and action strategies than did the interpersonal perspective. We close with a discussion both of how wisdom appears to span across different fields and how the present results might feed into the teaching of wisdom in schools.

  19. Personal pronouns and perspective taking in toddlers.

    PubMed

    Ricard, M; Girouard, P C; Décarie, T G

    1999-10-01

    This study examined the evolution of visual perspective-taking skills in relation to the comprehension and production of first, second and third person pronouns. Twelve French-speaking and 12 English-speaking children were observed longitudinally from 1.6 until they had acquired all pronouns and succeeded on all tasks. Free-play sessions and three tasks were used to test pronominal competence. Four other tasks assessed Level-1 perspective-taking skills: two of these tasks required the capacity to consider two visual perspectives, and two others tested the capacity to coordinate three such perspectives. The results indicated that children's performance on perspective-taking tasks was correlated with full pronoun acquisition. Moreover, competence at coordinating two visual perspectives preceded the full mastery of first and second person pronouns, and competence at coordinating three perspectives preceded the full mastery of third person pronouns when a strict criterion was adopted. However, with less stringent criteria, the sequence from perspective taking to pronoun acquisition varied either slightly or considerably. These findings are discussed in the light of the 'specificity hypothesis' concerning the links between cognition and language, and also in the context of the recent body of research on the child's developing theory of mind.

  1. Evolution of Theoretical Perspectives in My Research

    NASA Astrophysics Data System (ADS)

    Otero, Valerie K.

    2009-11-01

    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.

  2. Sexual compliance: gender, motivational, and relationship perspectives.

    PubMed

    Impett, Emily A; Peplau, Letitia A

    2003-02-01

    This paper provides a systematic review of research on sexual compliance in heterosexual relationships. Three perspectives shed light on which individuals are the most likely to comply with a sexually interested partner's desire for sex and why. A gender perspective highlights the common male-female asymmetry in compliant sexual behavior and identifies factors that contribute to women's greater likelihood of being the sexually compliant partner. A motivational perspective distinguishes between approach and avoidance motives for compliance and considers the possible consequences of these motives for emotional reactions, sexual risk taking, and sexual violence. A relationship maintenance perspective views sexual compliance as illustrative of broader patterns of sacrifice in committed relationships. Each perspective suggests important new directions for empirical research.

  3. Perspectives on Aging Vestibular Function

    PubMed Central

    Anson, Eric; Jeka, John

    2016-01-01

    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.

  4. [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.

  5. Technology Adoption: an Interaction Perspective

    Sitorus, Hotna M.; Govindaraju, Rajesri; Wiratmadja, I. I.; Sudirman, Iman

    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.

  6. Decent Work: A Psychological Perspective

    PubMed Central

    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).

  7. Medical cannabis - the Canadian perspective.

    PubMed

    Ko, Gordon D; Bober, Sara L; Mindra, Sean; Moreau, Jason M

    2016-01-01

    Cannabis has been widely used as a medicinal agent in Eastern medicine with earliest evidence in ancient Chinese practice dating back to 2700 BC. Over time, the use of medical cannabis has been increasingly adopted by Western medicine and is thus a rapidly emerging field that all pain physicians need to be aware of. Several randomized controlled trials have shown a significant and dose-dependent relationship between neuropathic pain relief and tetrahydrocannabinol - the principal psychoactive component of cannabis. Despite this, barriers exist to use from both the patient perspective (cost, addiction, social stigma, lack of understanding regarding safe administration) and the physician perspective (credibility, criminality, clinical evidence, patient addiction, and policy from the governing medical colleges). This review addresses these barriers and draws attention to key concerns in the Canadian medical system, providing updated treatment approaches to help clinicians work with their patients in achieving adequate pain control, reduced narcotic medication use, and enhanced quality of life. This review also includes case studies demonstrating the use of medical marijuana by patients with neuropathic low-back pain, neuropathic pain in fibromyalgia, and neuropathic pain in multiple sclerosis. While significant preclinical data have demonstrated the potential therapeutic benefits of cannabis for treating pain in osteoarthritis, rheumatoid arthritis, fibromyalgia, and cancer, further studies are needed with randomized controlled trials and larger study populations to identify the specific strains and concentrations that will work best with selected cohorts.

  8. Theoretical perspectives on narrative inquiry.

    PubMed

    Emden, C

    1998-04-01

    Narrative inquiry is gaining momentum in the field of nursing. As a research approach it does not have any single heritage of methodology and its practitioners draw upon diverse sources of influence. Central to all narrative inquiry however, is attention to the potential of stories to give meaning to people's lives, and the treatment of data as stories. This is the first of two papers on the topic and addresses the theoretical influences upon a particular narrative inquiry into nursing scholars and scholarship. The second paper, Conducting a narrative analysis, describes the actual narrative analysis as it was conducted in this same study. Together, the papers provide sufficient detail for others wishing to pursue a similar approach to do so, or to develop the ideas and procedures according to their own way of thinking. Within this first theoretical paper, perspectives from Jerome Bruner (1987) and Wade Roof (1993) are outlined. These relate especially to the notion of stories as 'imaginative constructions' and as 'cultural narratives' and as such, highlight the profound importance of stories as being individually and culturally meaningful. As well, perspectives on narrative inquiry from nursing literature are highlighted. Narrative inquiry in this instance lies within the broader context of phenomenology.

    Molecular imprinting technology (MIT), often described as a method of making a molecular lock to match a molecular key, is a technique for the creation of molecularly imprinted polymers (MIPs) with tailor-made binding sites complementary to the template molecules in shape, size and functional groups. Owing to their unique features of structure predictability, recognition specificity and application universality, MIPs have found a wide range of applications in various fields. Herein, we propose to comprehensively review the recent advances in molecular imprinting including versatile perspectives and applications, concerning novel preparation technologies and strategies of MIT, and highlight the applications of MIPs. The fundamentals of MIPs involving essential elements, preparation procedures and characterization methods are briefly outlined. Smart MIT for MIPs is especially highlighted including ingenious MIT (surface imprinting, nanoimprinting, etc.), special strategies of MIT (dummy imprinting, segment imprinting, etc.) and stimuli-responsive MIT (single/dual/multi-responsive technology). By virtue of smart MIT, new formatted MIPs gain popularity for versatile applications, including sample pretreatment/chromatographic separation (solid phase extraction, monolithic column chromatography, etc.) and chemical/biological sensing (electrochemical sensing, fluorescence sensing, etc.). Finally, we propose the remaining challenges and future perspectives to accelerate the development of MIT, and to utilize it for further developing versatile MIPs with a wide range of applications (650 references).

    2015-01-01

    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.

    1992-10-01

    Utilization of water as an inexhaustible supply of a fuel (hydrogen) was predicted over a century ago by Jules Verne in The Mysterious Island. Since the oil crisis of 1973, considerable progress has been made in the search for alternative energy supplies. Although the water splitting process to generate simultaneously hydrogen and oxygen has been demonstrated (albeit the process is inefficient) by utilization of light energy, the technology is not mature enough to seriously bring it to pilot-plant demonstration. Much fundamental research remains to be done. The present paper examines the present status and looks at the perspectives of the technological progress, particularly in the high temperature thermochemical and photochemical fields with emphasis in the utilization of solar quantum and thermal photons.

    This is an invited article for the Discussion and Debate special issue of The European Physical Journal Special Topics on the subject "Can Economics be a Physical Science?" The first part of the paper traces the personal path of the author from theoretical physics to economics. It briefly summarizes applications of statistical physics to monetary transactions in an ensemble of economic agents. It shows how a highly unequal probability distribution of money emerges due to irreversible increase of entropy in the system. The second part examines deep conceptual and controversial issues and fallacies in monetary economics from econophysics perspective. These issues include the nature of money, conservation (or not) of money, distinctions between money vs. wealth and money vs. debt, creation of money by the state and debt by the banks, the origins of monetary crises and capitalist profit. Presentation uses plain language understandable to laypeople and may be of interest to both specialists and general public.

    Mead, S; Hilton, D; Curtis, L

    2001-01-01

    This article offers one theoretical perspective of peer support and attempts to define the elements that, when reinforced through education and training, provide a new cultural context for healing and recovery. Persons labeled with psychiatric disability have become victims of social and cultural ostracism and consequently have developed a sense of self that reinforces the "patient" identity. Enabling members of peer support to understand the nature and impact of these cultural forces leads individuals and peer communities toward a capacity for personal, relational, and social change. It is our hope that consumers from all different types of programs (e.g. drop-in, social clubs, advocacy, support, outreach, respite), traditional providers, and policy makers will find this article helpful in stimulating dialogue about the role of peer programs in the development of a recovery based system.

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.

    2005-01-01

    This paper emphasizes how marketing can make a difference in repeat donations by volunteer blood donors, since the greatest challenge for health institutions is to maintain and increase blood donation. In this context, understanding volunteer donors' motivations is highly important, and the studies reported here demonstrate that several variables are relevant to blood donation. The huge number of patients in need of blood transfusions and the lack of sufficient blood and blood products justify the interest in this study, considering both donors' and blood banks' perspectives. Moreover, recognition of the importance of actions and orientation for donors is fundamental for developing a marketing strategy. It is thus relevant for health institutions to identify donors' actual needs and wishes.

    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

    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.

    Inhibin is generally considered to be a feedback regulator of FSH secretion, but significant progress in the field of inhibin biology over the past four years has widened our perspective of inhibin and its production, regulation and action. Firstly, inhibin is a member of a larger family of hormones, secondly it is produced by organs other than the gonads, and thirdly its action is not confined to the pituitary gland. In this review we will outline the isolation and characterization of inhibin related peptides and their production by the Sertoli and granulosa cells of the testis and ovary. With this information in mind, more recent studies concerning the measurement, production, regulation and action of inhibin and inhibin-related proteins will be discussed, in an effort to alert the reader to the contemporary and controversial issues concerning inhibin biology.

    Chikungunya virus (CHIKV) is a mosquito-borne pathogen that has a major health impact in humans and causes acute febrile illness in humans accompanied by joint pains and, in many cases, persistent arthralgia lasting for weeks to years. CHIKV reemerged in 2005-2006 in several parts of the Indian Ocean islands and India after a gap of 32 years, causing millions of cases. The re-emergence of CHIKV has also resulted in numerous outbreaks in several countries in the eastern hemisphere, with a threat to further expand in the near future. However, there is no vaccine against CHIKV infection licensed for human use, and therapy for CHIKV infection is still mainly limited to supportive care as antiviral agents are yet in different stages of testing or development. In this review we explore the different perspectives for chikungunya treatment and the effectiveness of these treatment regimens and discuss the scope for future directions. PMID:24955364

  5. 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.

    This collection of papers describes research that goes into detail on some of the more important issues in the physics of stimulated Brillouin scattering. This perspective describes the earliest years of the physics of stimulated Brillouin scattering, along with key developments that have led to this technically and physically rich field of today’s nonlinear optics. Stimulated Brillouin has a profound effect in optical fiber communications, initially discovered by its limit on the transmitted power. By controlling SBS in fibers and making use of its phase conjugation properties in both fibers and bulk media, a wide range of applications have been enabled. Today ring Brillouin lasers in fibers, whispering gallery modes and in photonic integrated circuits provide optical delay lines and switches, pulse shapers and components for increasingly complex and important optical systems.

    2011-01-01

    Crohn's disease (CD) is known for wide anatomic distribution, different presentations, life-threatening complications, and multiple modalities of management. Its multiple implications are still unaddressed. Since all the patients do not show a good response to medical modalities of treatment, a significant percentage of these patients are referred to the surgeon for the palliation of complications or for the ultimate curative treatment. Since most surgeons come across such patients only rarely, it is sometimes difficult for them to choose the appropriate procedure at the time of need. Moreover, the various surgical modalities available for the different presentations and complications of the disease have not been adequately discussed. The aim of this review is to offer insight and a detailed account of the management of CD from a surgical perspective. This review offers an overview of the various surgical options available, their utility in context, and an approach to various scenarios of complicated CD.

  8. Sparsity and the Bayesian perspective

    Starck, J.-L.; Donoho, D. L.; Fadili, M. J.; Rassat, A.

    2013-04-01

    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.

    Populations that are underrepresented in physics generally are even more severely underrepresented among US physics teachers. Based on national data from the American Institute of Physics (AIP), 95% of physics teachers are White/non-Hispanic, about 1.5% are Hispanic, and approximately another 1.5% African-American. While 25% of our nation's African-American and Hispanic students now take physics in high school, they are very unlikely to have a role model, of similar race and ethnicity, teaching their physics classes. PhysTEC is making an effort to find and disseminate successful models for attracting more underrepresented minority students to high school physics teaching. This panel discussion, focusing on cultural perspectives on teacher education, will feature faculty from Minority Serving Institutions, which educate almost 60% of underrepresented minorities who get college degrees in the US, and individuals who have taught high school physics in areas with a dense minority population.

  10. New perspectives on red supergiants

    There is a high interest in cool supergiants (CSGs), because they play a key role in the understanding of the evolution and death of massive stars: most high-mass stars pass through this phase at some point of their evolution, and the physical conditions during it will determine their subsequent evolution. In addition, these stars are a powerful high-mass stellar formation tracers and also the main progenitors of core-collapse supernovae (SNe). Despite this, they are poorly characterized in some aspects: their extreme sizes and peculiar conditions defy the predictions of present-day atmospheric and evolutionary models. To bring perspective to this topic, we investigate the behaviour of CSGs as a population. For this, we studied the largest homogeneous multiepoch spectroscopic sample of CSGs (from the SMC and LMC) to date (>500). Our results give a new global view about the physical conditions of CSGs and their evolution

    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.

  12. Memory distortion: an adaptive perspective

    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.

    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.

  14. Symbolic enhancement of perspective displays

    1990-01-01

    Two exocentric azimuth judgment experiments with a perspective display were conducted with 16 subjects. Previous work has shown these judgments to exhibit a bias possibly due to misinterpretation of the viewing parameters used to generate the display. Though geometric compensations may be used to correct for the bias, an alternate technique selected in the following 2 experiments was the introduction of symbolic enhancements in the form of compass roses. It is suggested that a compass rose with 30 deg divisions results in overall optimal azimuth estimation accuracy when accuracy and decision time are both considered. The data also suggest that the added radial lines on the compass roses may interact with normalization processes that influence the judgment errors.

    2015-04-01

    Photometric stereo is a technique for estimating the 3-D depth of a surface using multiple images taken under different illuminations from the same viewing angle. Most existing models make use of Lambertian reflection and an orthographic camera as underlying assumptions. However, real-world materials often exhibit non-Lambertian effects such as specular highlights and for many applications it is of interest to consider objects close to the camera. In our work, we aim at addressing these issues. Together with a perspective camera we employ a non-Lambertian reflectance model, namely the Blinn-Phong model which is capable to deal with specular reflection. Focusing on the effects of specular highlights, we perform a detailed study of one-dimensional test cases showing important aspects of our method.

    Synthetic biology aims at manipulating biological systems by rationally designed and genetically introduced components. Efforts in photoactuator engineering resulted in microorganisms reacting to extracellular light-cues with various cellular responses. Some of them lead to the formation of macroscopically observable outputs, which can be used to generate images made of living matter. Several methods have been developed to convert colorless compounds into visible pigments by an enzymatic conversion. This has been exploited as a showcase for successful creation of an optogenetic tool; examples for basic light-controlled biological processes that have been coupled to this biophotography comprise regulation of transcription, protein stability, and second messenger synthesis. Moreover, biological reproduction of images is used as means to facilitate quantitative characterization of optogenetic switches as well as a technique to investigate complex cellular signaling circuits. Here, we will compare the different techniques for biological image generation, introduce experimental approaches, and provide future-perspectives for biophotography.

  17. Perspectives on sustainable waste management.

    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.

    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.

  1. Inferring Perspective Versus Getting Perspective: Underestimating the Value of Being in Another Person's Shoes.

    PubMed

    Zhou, Haotian; Majka, Elizabeth A; Epley, Nicholas

    2017-04-01

    People use at least two strategies to solve the challenge of understanding another person's mind: inferring that person's perspective by reading his or her behavior (theorization) and getting that person's perspective by experiencing his or her situation (simulation). The five experiments reported here demonstrate a strong tendency for people to underestimate the value of simulation. Predictors estimated a stranger's emotional reactions toward 50 pictures. They could either infer the stranger's perspective by reading his or her facial expressions or simulate the stranger's perspective by watching the pictures he or she viewed. Predictors were substantially more accurate when they got perspective through simulation, but overestimated the accuracy they had achieved by inferring perspective. Predictors' miscalibrated confidence stemmed from overestimating the information revealed through facial expressions and underestimating the similarity in people's reactions to a given situation. People seem to underappreciate a useful strategy for understanding the minds of others, even after they gain firsthand experience with both strategies.

    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.

    The present experiment was designed to examine the roles of painted linear perspective cues, and the convexity bias that are known to influence human observers' perception of three-dimensional (3D) objects and scenes. Reverse-perspective stimuli were used to elicit a depth-inversion illusion, in which far points on the stimulus appear to be closer than near points and vice versa, with a 2 (Type of stimulus) × 2 (Fixation mark position) design. To study perspective, two types of stimuli were used: a version with painted linear perspective cues and a version with blank (unpainted) surfaces. To examine the role of convexity, two locations were used for the fixation mark: either in a locally convex or a locally concave part of each stimulus (painted and unpainted versions). Results indicated that the reverse-perspective illusion was stronger when the stimulus contained strong perspective cues and when observers fixated a locally concave region within the scene.

  5. Mental imagery of positive and neutral memories: A fMRI study comparing field perspective imagery to observer perspective imagery.

    2017-02-01

    Imagery perspective can influence what information is recalled, processing style, and emotionality; however, the understanding of possible mechanisms mediating these observed differences is still limited. We aimed to examine differences between memory recall from a field perspective and observer perspective at the neurobiological level, in order to improve our understanding of what is underlying the observed differences at the behavioral level. We conducted a fMRI study in healthy individuals, comparing imagery perspectives during recall of neutral and positive autobiographical memories. Behavioral results revealed field perspective imagery of positive memories, as compared to observer perspective, to be associated with more positive feelings afterwards. At the neurobiological level, contrasting observer perspective to field perspective imagery was associated with greater activity, or less decrease relative to the control visual search task, in the right precuneus and in the right temporoparietal junction (TPJ). Greater activity in the right TPJ during an observer perspective as compared to field perspective could reflect performing a greater shift of perspective and mental state during observer perspective imagery than field perspective imagery. Differential activity in the precuneus may reflect that during observer perspective imagery individuals are more likely to engage in (self-) evaluative processing and visuospatial processing. Our findings contribute to a growing understanding of how imagery perspective can influence the type of information that is recalled and the intensity of the emotional response. Observer perspective imagery may not automatically reduce emotional intensity but this could depend on how the imagined situation is evaluated in relation to the self-concept.

  7. Perceived perspective taking: when others walk in our shoes.

    A great deal of psychological research has investigated the influence of perspective taking on individuals, indicating that perspective taking increases the extent to which people like, feel a sense of self-other overlap with, and help those whose perspective they take. However, previous investigations of the topic have been limited to the study of the perspective taker, rather than the individual whose perspective has been taken. The purpose of the current work is to begin to fill this large gap in the literature by examining the consequences of believing that another individual is taking one's perspective, a phenomenon we refer to as perceived perspective taking. Over a series of 6 experiments, we demonstrate that perceiving that one's perspective has been taken confers many of the same interpersonal benefits as taking another's perspective. Specifically, our data suggest that believing that another person has successfully taken one's perspective results in an increased liking for, a greater sense of self-other overlap with, and more help provided to that person. Consistent with predictions, we find that one's self-other overlap with the perspective taker and the amount of empathy one perceives the perspective taker to feel operate in tandem to mediate the link between perceived perspective taking and liking for the perspective taker. Further, a mediational path from perceived perspective taking to helping behavior through liking is supported. Future directions are discussed, along with implications for theory and application in domains such as intergroup relations, conflict resolution, and political campaigning.

    Through interspacecraft comparison of energetic neutral oxygen (ENO) intensity from two different vantage points provided by IMAGE and Geotail, Lui et al. (2005) showed that viewing perspective plays a very important role in the observed ENO intensity level during a magnetic storm period. Motivated by the findings of Lui et al. (2005), we investigate how viewing perspective influences energetic neutral atom emissions from a modeling perspective. The main results of this paper are that (1) our simulation results, based upon O+ ion fluxes from the Comprehensive Ring Current Model and the subsequent ENO calculation, reproduce the total differential ENO intensity obtained from two spacecraft to a reasonable degree and (2) further analysis of our results indicates that pitch angle anisotropy in ring current ion flux, a crucial physical quantity in ring current dynamics, is one major contributor to the difference in energetic neutral atom intensity from different viewing perspectives.

A multiscience perspective recognizes the existence of various types of science at play in all science classrooms, especially personal science, indigenous science, and Western modem science.

  19. Changing perspective: The role of vestibular signals.

    PubMed

    Deroualle, Diane; Borel, Liliane; Devèze, Arnaud; Lopez, Christophe

    2015-12-01

    Social interactions depend on mechanisms such as the ability to take another person's viewpoint, i.e. visuo-spatial perspective taking. However, little is known about the sensorimotor mechanisms underpinning perspective taking. Because vestibular signals play roles in mental rotation and spatial cognition tasks and because damage to the vestibular cortex can disturb egocentric perspective, vestibular signals stand as important candidates for the sensorimotor foundations of perspective taking. Yet, no study merged natural full-body vestibular stimulations and explicit visuo-spatial perspective taking tasks in virtual environments. In Experiment 1, we combined natural vestibular stimulation on a rotatory chair with virtual reality to test how vestibular signals are processed to simulate the viewpoint of a distant avatar. While they were rotated, participants tossed a ball to a virtual character from the viewpoint of a distant avatar. Our results showed that vestibular signals influence perspective taking in a direction-specific way: participants were faster when their physical body rotated in the same direction as the mental rotation needed to take the avatar's viewpoint. In Experiment 2, participants realized 3D object mental rotations, which did not involve perspective taking, during the same whole-body vestibular stimulation. Our results demonstrated that vestibular stimulation did not affect 3D object mental rotations. Altogether, these data indicate that vestibular signals have a direction-specific influence on visuo-spatial perspective taking (self-centered mental imagery), but not a general effect on mental imagery. Findings from this study suggest that vestibular signals contribute to one of the most crucial mechanisms of social cognition: understanding others' actions.

  20. The Perspective Structure of Visual Space.

    PubMed

    Erkelens, Casper J

    2015-10-01

    Luneburg's model has been the reference for experimental studies of visual space for almost seventy years. His claim for a curved visual space has been a source of inspiration for visual scientists as well as philosophers. The conclusion of many experimental studies has been that Luneburg's model does not describe visual space in various tasks and conditions. Remarkably, no alternative model has been suggested. The current study explores perspective transformations of Euclidean space as a model for visual space. Computations show that the geometry of perspective spaces is considerably different from that of Euclidean space. Collinearity but not parallelism is preserved in perspective space and angles are not invariant under translation and rotation. Similar relationships have shown to be properties of visual space. Alley experiments performed early in the nineteenth century have been instrumental in hypothesizing curved visual spaces. Alleys were computed in perspective space and compared with reconstructed alleys of Blumenfeld. Parallel alleys were accurately described by perspective geometry. Accurate distance alleys were derived from parallel alleys by adjusting the interstimulus distances according to the size-distance invariance hypothesis. Agreement between computed and experimental alleys and accommodation of experimental results that rejected Luneburg's model show that perspective space is an appropriate model for how we perceive orientations and angles. The model is also appropriate for perceived distance ratios between stimuli but fails to predict perceived distances.

  1. Perspective View, San Andreas Fault

    The prominent linear feature straight down the center of this perspective view is the San Andreas Fault in an image created with data from NASA's shuttle Radar Topography Mission (SRTM), which will be used by geologists studying fault dynamics and landforms resulting from active tectonics. This segment of the fault lies west of the city of Palmdale, California, about 100 kilometers (about 60 miles) northwest of Los Angeles. The fault is the active tectonic boundary between the North American plate on the right, and the Pacific plate on the left. Relative to each other, the Pacific plate is moving away from the viewer and the North American plate is moving toward the viewer along what geologists call a right lateral strike-slip fault. This area is at the junction of two large mountain ranges, the San Gabriel Mountains on the left and the Tehachapi Mountains on the right. Quail Lake Reservoir sits in the topographic depression created by past movement along the fault. Interstate 5 is the prominent linear feature starting at the left edge of the image and continuing into the fault zone, passing eventually over Tejon Pass into the Central Valley, visible at the upper left.

    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.

    This perspective view shows the western side of the volcanically active Kamchatka Peninsula, Russia. The data are from the first C-band mapping swath of the Shuttle Radar Topography Mission (SRTM). In the foreground is the broad, flat floodplain of the Amanina River, shown in blue. In background of the image is the Sredinnyy Khrebet, the volcanic mountain range that makes up the 3spine2 of the peninsula. The cluster of hills in the upper right is a field of small dormant volcanoes. High resolution SRTM topographic data will be used by geologists to study how volcanoes form and understand the hazards posed by future eruptions.

    This shaded relief perspective view was generated using topographic data from the Shuttle Radar Topography Mission. A computer-generated artificial light source illuminates the elevation data to produce a pattern of light and shadows. Slopes facing the light appear bright, while those facing away are shaded. On flatter surfaces, the pattern of light and shadows can reveal subtle features in the terrain. Colors show the elevation as measured by SRTM. Colors range from blue at the lowest elevations to white at the highest elevations. This image contains about 2300 meters (7500 feet) of total relief. To emphasize subtle differences in topography, the relief is exaggerated by a factor of 5.

    The Shuttle Radar Topography Mission (SRTM), launched on February 11,2000, uses 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. The mission is 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, an additional C-band imaging antenna and improved tracking and navigation devices. The mission is a cooperative project between the National Aeronautics and Space Administration (NASA), the National Imagery and Mapping Agency (NIMA) and the

Organization becomes cause in the matter. Nat. Biotechnol. 18, 575-576]. I present Bateson's idea that organisms have a "recursive hierarchical" form of organization [Neuman, Y., 2004.

  6. Sustainability Transitions as new perspective

    Rotmans, J.

    2012-04-01

    Sustainability transitions are radical transformations towards a sustainable society as a response to a number of persistent problems confronting contemporary modern societies. The most striking example of such a persistent problem is the current economic and financial crisis. This crisis is only a symptom of a deeper-lying systems crisis, which is rooted in the disbalance between overly consuming and producing during the last decennia on the one hand and exhausting our natural resources and materials on the other hand. The perverse effects of this disbalance are not accounted for in the economic order that we have created. This means that the economic order is not sustainable in the long run. Without a fundamental shift, a transition, to a new, sustainable economy, we will revert to old patterns and mechanisms that will automatically generate the next crises. In this transition process we are at a turning point. On the verge of a new era, characterized by a battle of the old paradigm against the new one, with a crucial role for sustainable innovation. Such a transition perspective might help to unravel the unprecedented complexity of the interrelated economic, financial, energy and climate crisis and to shed some light on structural, sustainable solutions.

    Dancers are clearly athletes in the degree to which sophisticated physical capacities are required to perform at a high level. The standard complement of athletic attributes - muscular strength and endurance, anaerobic and aerobic energy utilization, speed, agility, coordination, motor control, and psychological readiness - all are essential to dance performance. In dance, as in any athletic activity, injuries are prevalent. This paper presents the research background of dance injuries, characteristics that distinguish dance and dancers from traditional sports and athletes, and research-based perspectives into how dance injuries can be reduced or prevented, including the factors of physical training, nutrition and rest, flooring, dancing en pointe, and specialized health care access for dancers. The review concludes by offering five essential components for those involved with caring for dancers that, when properly applied, will assist them in decreasing the likelihood of dance-related injury and ensuring that dancers receive optimum attention from the health care profession: (1) screening; (2) physical training; (3) nutrition and rest; (4) specialized dance health care; and (5) becoming acquainted with the nature of dance and dancers.

  8. Human adoption in evolutionary perspective.

    Silk, J B

    1990-03-01

    Exploitation is a fundamental element of the parental strategies of many species of birds. Cuckoos, for example, lay their eggs in the nest of other birds, who often unwittingly rear the alien nestlings as their own. Nest parasitism is an efficient reproductive strategy for cuckoos, who do not have to worry about building a nest, incubating their eggs, or feeding their nestlings. But not all hosts respond passively to such intrusions. In response to parasitic cowbirds, for example, robins have evolved the ability to detect and selectively eject alien young from their nests. Human parenting strategies differ sharply from the strategies of cuckoos and robins. Unlike cuckoos, we are reluctant to allow our children to be raised by others. Unlike robins, we knowingly rear strange young. What makes human behavior toward children so different from that of cuckoos and robins? Humans seem to share a number of predispositions that facilitate successful adoptive relationships, and the desire to raise children seems to be pervasive among modern humans. Despite these commonalities, patterns of adoption transactions vary greatly among contemporary human societies. This paper considers the origins and causes of cross-cultural variation in human adoptive behavior from an evolutionary perspective.

  9. Biocultural perspectives on women's health.

    PubMed

    1997-04-01

    During the 1997 meeting of the American Association for the Advancement of Science, a session was devoted to biocultural perspectives on women's health in developing countries. The topics covered included female circumcision conducted as part of the traditional wedding ceremony of the Rendille people of Kenya and the deleterious effect of sociocultural factors such as acceptance of premarital sexual intercourse and early child-bearing on the health of adolescent girls in West Africa. A study in Bangladesh sought information on women's health during pregnancy and lactation. Using 19,000 paired questionnaires and urine samples from 493 women representing all reproductive states, pregnancy-related sickness (such as nausea and vomiting) was correlated to hormone levels, maternal age, and fetal loss. Preliminary results contradict a popular belief that incidence of pregnancy-related sickness is associated with a lowered risk of early fetal loss. Another study in Bangladesh revealed that previous research indicating that women in Bangladesh experience menopause eight years sooner than US women was inaccurate. The two-year earlier onset of menopause found in Bangladesh is likely caused by stress-related anovulation. A preliminary literature review has also shown that Bangladeshi women lack significant amounts of phytoestrogens in their diet. Improved knowledge of biocultural factors is sought as a prerequisite for improving medical treatment in developed and developing countries.

  10. Evolutionary Perspective in Child Growth

    2011-01-01

    Hereditary, environmental, and stochastic factors determine a child’s growth in his unique environment, but their relative contribution to the phenotypic outcome and the extent of stochastic programming that is required to alter human phenotypes is not known because few data are available. This is an attempt to use evolutionary life-history theory in understanding child growth in a broad evolutionary perspective, using the data and theory of evolutionary predictive adaptive growth-related strategies. Transitions from one life-history phase to the next have inherent adaptive plasticity in their timing. Humans evolved to withstand energy crises by decreasing their body size, and evolutionary short-term adaptations to energy crises utilize a plasticity that modifies the timing of transition from infancy into childhood, culminating in short stature in times of energy crisis. Transition to juvenility is part of a strategy of conversion from a period of total dependence on the family and tribe for provision and security to self-supply, and a degree of adaptive plasticity is provided and determines body composition. Transition to adolescence entails plasticity in adapting to energy resources, other environmental cues, and the social needs of the maturing adolescent to determine life-span and the period of fecundity and fertility. Fundamental questions are raised by a life-history approach to the unique growth pattern of each child in his given genetic background and current environment. PMID:23908815

    2007-01-01

    Approximately twenty five years ago a novel proposal was made to explain two of the outstanding cosmological conundrums, namely those of the Horizon Problem and the Flatness Problem of the Universe. These are the fact that widely separated parts of the sky that have never been in causal contact during the evolution of the Universe have apparently the same CMB temperature and the fact that the mean density of the Universe is very close to the critical one, i.e. very close to the density that separates the closed and open models. These coincidences implied that the corresponding initial condition of the Universe must have been set to exquisite accuracy. This novel proposal posted that at these very early times, the energy density of the Universe was dominated by a fluid which had the equation state attributed to the vacuum (i.e. dominated by tension rather than pressure) and that this led to an exponential expansion of the Universe which was "inflated" by many orders of magnitude of its original size. It was then shown that this "inflation" could provide a resolution of the above outstanding problems. The talk will cover the speaker's personal perspective and contributions to this idea and the subsequent developments over the following 25 years since its inception.

    Hair loss is a commonly encountered problem in clinical practice, with men presenting with a distinctive pattern involving hairline recession and vertex balding (Norwood-Hamilton classification) and women exhibiting diffuse hair thinning over the crown (increased part width) and sparing of the frontal hairline (Ludwig classification). Female pattern hair loss has a strikingly overwhelming psychological effect; thus, successful treatments are necessary. Difficulty lies in successful treatment interventions, as only two medications – minoxidil and finasteride – are approved for the treatment of androgenetic alopecia, and these medications offer mediocre results, lack of a permanent cure, and potential complications. Hair transplantation is the only current successful permanent option, and it requires surgical procedures. Several other medical options, such as antiandrogens (eg, spironolactone, oral contraceptives, cyproterone, flutamide, dutasteride), prostaglandin analogs (eg, bimatoprost, latanoprost), and ketoconazole are reported to be beneficial. Laser and light therapies have also become popular despite the lack of a profound benefit. Management of expectations is crucial, and the aim of therapy, given the current therapeutic options, is to slow or stop disease progression with contentment despite patient expectations of permanent hair regrowth. This article reviews current perspectives on therapeutic options for female pattern hair loss. PMID:24039457

  13. Entropy estimation in Turing's perspective.

    PubMed

    Zhang, Zhiyi

    2012-05-01

    A new nonparametric estimator of Shannon's entropy on a countable alphabet is proposed and analyzed against the well-known plug-in estimator. The proposed estimator is developed based on Turing's formula, which recovers distributional characteristics on the subset of the alphabet not covered by a size-n sample. The fundamental switch in perspective brings about substantial gain in estimation accuracy for every distribution with finite entropy. In general, a uniform variance upper bound is established for the entire class of distributions with finite entropy that decays at a rate of O(ln(n)/n) compared to O([ln(n)]2/n) for the plug-in. In a wide range of subclasses, the variance of the proposed estimator converges at a rate of O(1/n), and this rate of convergence carries over to the convergence rates in mean squared errors in many subclasses. Specifically, for any finite alphabet, the proposed estimator has a bias decaying exponentially in n. Several new bias-adjusted estimators are also discussed.

    2015-01-01

    The schizotypy construct focuses attention on the liability to develop schizophrenia-spectrum disorders, yet traditionally, the schizotypy models have put more emphasis on stress-vulnerability interactions rather than developmental dynamics of emerging risk for psychopathology. Indeed, developmental accounts of this emerging personality trait have rarely been explicitly formulated. In this position article, we wish to convey some of the basic developmental tenets of schizotypy, and how they can inform high-risk research. Firstly, we tackle the state vs trait issue to outline the possible relationship between high-risk states and trait schizotypy. Second, we review the evidence suggesting that the consolidation of schizotypy, encompassing its 3 main dimensions, could be considered as a developmental mediator between very early risk factors and transition into high-risk states. Importantly, developmental dynamics between endophenotypes, as well as transactional and epigenetics mechanisms should enter modern conceptualizations of schizotypy. Finally, we present a developmental psychopathology perspective of schizotypy sensitive to both the multifinality and equifinality of schizophrenia-spectrum disorders. We conclude that schizotypy represents a crucial construct in a fully-developmental study of schizophrenia-spectrum disorders. PMID:25548385

    Space weather, just like its meteorological counterpart, is of extreme importance when it comes to its impact on terrestrial near- and far-space environments. In recent years, space weather research has acquired an important place as a thrust area of research having implications both in space science and technology. The presence of satellites and other technological systems from different nations in near-Earth space necessitates that one must have a comprehensive understanding not only of the origin and evolution of space weather processes but also of their impact on technology and terrestrial upper atmosphere. To address this aspect, nations across the globe including India have been investing in research concerning Sun, solar processes and their evolution from solar interior into the interplanetary space, and their impact on Earth's magnetosphere-ionosphere-thermosphere system. In India, over the years, a substantial amount of work has been done in each of these areas by various agencies/institutions. In fact, India has been, and continues to be, at the forefront of space research and has ambitious future programs concerning these areas encompassing space weather. This review aims at providing a glimpse of this Indian perspective on space weather research to the reader and presenting an up-to-date status of the same.

    As a continuation of its work and of the seminar on nursing sciences education in 2014, the “Association de recherche en soins infirmiers” (Arsi) organized a seminar on the 3rd and-4th of June 2016 in Nantes entitled : “nursing : perspectives and foresights”. More than fifty participants from the francophone area representing various sectors of practice : clinical, teaching, management and students gathered to debate and produce benchmarks to support the development of nursing sciences in France and to draw future directions for clinical practice and training. The successive sessions made it possible to reflect, to confront opinions, to make proposals and to identify the terms of the problematic of care and nursing knowledge today and the methodological elements relating to foresight. At the end of this very creative seminar, new avenues of reflection emerged shifting our usual look at the nurse profession. Orientations for training and practice have been defined with different stakes depending on the level of training and professional commitment. The strong links between professional, scientific and academic discipline have also been clarified, highlighting the importance to hold a high theoretical and scientific requirement, rigorous clinical practice, strong professional commitment and effective leadership.

  18. Infrastructure Commons in Economic Perspective

    NASA Astrophysics Data System (ADS)

    Frischmann, Brett M.

    This chapter briefly summarizes a theory (developed in substantial detail elsewhere)1 that explains why there are strong economic arguments for managing and sustaining infrastructure resources in an openly accessible manner. This theory facilitates a better understanding of two related issues: how society benefits from infrastructure resources and how decisions about how to manage or govern infrastructure resources affect a wide variety of public and private interests. The key insights from this analysis are that infrastructure resources generate value as inputs into a wide range of productive processes and that the outputs from these processes are often public goods and nonmarket goods that generate positive externalities that benefit society as a whole. Managing such resources in an openly accessible manner may be socially desirable from an economic perspective because doing so facilitates these downstream productive activities. For example, managing the Internet infrastructure in an openly accessible manner facilitates active citizen involvement in the production and sharing of many different public and nonmarket goods. Over the last decade, this has led to increased opportunities for a wide range of citizens to engage in entrepreneurship, political discourse, social network formation, and community building, among many other activities. The chapter applies these insights to the network neutrality debate and suggests how the debate might be reframed to better account for the wide range of private and public interests at stake.

    I discuss several novel and unexpected aspects of quantum chromodynamics. These include: (a) the nonperturbative origin of intrinsic strange, charm and bottom quarks in the nucleon at large x; the breakdown of pQCD factorization theorems due to the lensing effects of initial- and final-state interactions; (b) important corrections to pQCD scaling for inclusive reactions due to processes in which hadrons are created at high transverse momentum directly in the hard processes and their relation to the baryon anomaly in high-centrality heavy-ion collisions; and (c) the nonuniversality of quark distributions in nuclei. I also discuss some novel theoretical perspectives in QCD: (a) light-front holography - a relativistic color-confining first approximation to QCD based on the AdS/CFT correspondence principle; (b) the principle of maximum conformality - a method which determines the renormalization scale at finite order in perturbation theory yielding scheme independent results; (c) the replacement of quark and gluon vacuum condensates by 'in-hadron condensates' and how this helps to resolve the conflict between QCD vacuum and the cosmological constant.

  20. Assisted reproductive practice: religious perspectives.

    PubMed

    Schenker, Joscph G

    2005-03-01

    It is important to those who practise reproductive techniques to learn about different religious perspectives related to reproductive health problems. Religious groups are active in influencing the public regarding bioethical positions, and this is particularly evident with issues concerning procreation, abortion and infertility therapy. The Jewish attitude towards procreation is derived from the first commandment of God to Adam to 'Be fruitful and multiply'. Judaism allows the practice of all techniques of assisted reproduction when the oocyte and spermatozoon originate from the wife and husband respectively. The attitude toward reproductive practice varies among Christian groups. While assisted reproduction is not accepted by the Vatican, it may be practised by Protestant, Anglican and other denominations. According to traditional Christian views, beginning at conception, the embryo has moral status as a human being, and thus most assisted reproductive technologies are forbidden. According to Islam, the procedures of IVF and embryo transfer are acceptable, although they can be performed only for husband and wife. Developments in science and technology and corresponding clinical applications raise new religious questions, often without clear answers. The role of theology in bioethics is integral to clarify perceived attitudes toward these developments for different religious communities. This paper presents the attitude of monotheistic religions to therapeutic procedures, such as IVF-embryo transfer, spermatozoa, oocytes, embryo donation, cryopreservation of genetic material, surrogacy, posthumous reproduction, gender preselection, reproductive and therapeutic cloning.

    Hereditary, environmental, and stochastic factors determine a child's growth in his unique environment, but their relative contribution to the phenotypic outcome and the extent of stochastic programming that is required to alter human phenotypes is not known because few data are available. This is an attempt to use evolutionary life-history theory in understanding child growth in a broad evolutionary perspective, using the data and theory of evolutionary predictive adaptive growth-related strategies. Transitions from one life-history phase to the next have inherent adaptive plasticity in their timing. Humans evolved to withstand energy crises by decreasing their body size, and evolutionary short-term adaptations to energy crises utilize a plasticity that modifies the timing of transition from infancy into childhood, culminating in short stature in times of energy crisis. Transition to juvenility is part of a strategy of conversion from a period of total dependence on the family and tribe for provision and security to self-supply, and a degree of adaptive plasticity is provided and determines body composition. Transition to adolescence entails plasticity in adapting to energy resources, other environmental cues, and the social needs of the maturing adolescent to determine life-span and the period of fecundity and fertility. Fundamental questions are raised by a life-history approach to the unique growth pattern of each child in his given genetic background and current environment.

    A much greater part of our identity than we generally believe is collectively determined. Awareness of the causal link between identity, its connected values and the influence exerted by these values on perception is therefore crucial. In the implicit personality model of Peabody and Goldberg (1989), the apparent wide variety of human characteristics is broken down into three broad dimensions: general evaluation, impulse control and assertiveness. My hypothesis is that the regulation of impulses can be equated with the Jungian concept of the mother and father complexes, and assertiveness with the relation between individualism and collectivism. I have utilized Montgomery's perspective theory and Jung's concepts of the union of opposites, the complex and the shadow in order to provide an alternative interpretation of the implicit personality model. According to my interpretation, the traditional values of any culture can be read against these three dimensions. These values can be seen as the greatest treasure of a culture but, at the same time, they can also be devastating if they become complex-like.

    The Toronto Rehabilitation Institute (Toronto Rehab) is a current leader in the movement of interprofessional education (IPE) initiatives in Ontario, Canada. Nine students from seven different health care disciplines, including medicine, nursing, occupational therapy, pharmacy, physiotherapy, social work, and speech language pathology participated in the second IPE clinical placement in the winter of 2005 on Toronto Rehab's Stroke inpatient unit. In an effort to increase interprofessional collaboration, improve communication skills, foster respect and enhance knowledge of the different roles each discipline plays on the health care team, these students met together over a five week period and participated in interprofessional group sessions led by different health care professional leaders from the unit. This paper discusses the students' perspectives on this IPE experience and the corresponding benefits and challenges. All participants in the study recognized the importance of interprofessional teamwork in patient care and agreed that all health care education should include opportunities enabling them to develop the skills, behaviours and attitudes needed for interprofessional collaboration.

    This article is based on my own personal experience of having undergone “coma treatment” and being given approximately 37 coma injections between the period 1983–1993 despite the fact that I was not psychotic and was normal in every way. The experiences I had following the injections and the forcible administration of innumerable antipsychotics and drugs have shaped my perspective of what it is to be a victim of “iatrogenic” psychiatric treatment—iatrogenic because it induced symptoms of schizophrenia or at the least schizoidism in a normal person like me—an inability to think, feel, and reason, over time. I have also with my own eyes seen at least 7 or 8 women who look me (my clones) that has reinforced my belief that the injections split me. The British psychiatrist, Richard David Laing (Encyclopedia Britannica 2004 DVD [DVD]) also theorized that it is the division of the self that leads to the symptoms of schizophrenia such as splitting and fragmentation of the mind.

    Removal of a woman's ovaries (known as bilateral oophorectomy, ovariectomy or, historically, ovariotomy) is undertaken in a number of countries. An estimated 19 000 women aged <60 years had a bilateral prophylactic oophorectomy in the UK in 2003, either as a planned response to an increased specific genetic risk of ovarian or breast cancer or, more frequently, as a prophylactic measure to prevent ovarian cancer. Despite its popularity, however, a full evaluation of the risks, costs and benefits of prophylactic oophorectomy in the absence of genetic markers and at the time of hysterectomy has not yet been undertaken. This paper seeks to provide a historical perspective on current practice by outlining approaches to the ovary in Britain from the 19th century onwards. Historically, ovarian removal has raised many questions about the costs and benefits of surgery. The aim of this article is to highlight the issues, and in so doing, to contribute to a more informed assessment of current practice. PMID:17325391

    2013-07-01

    A great deal of attention is given to the importance of communication in environmental remediation and radioactive waste management. However, very little attention is given to eliciting multiple perspectives so as to formulate high quality decisions. Plans that are based on a limited number of perspectives tend to be narrowly focused whereas those that are based on a wide variety of perspectives tend to be comprehensive, higher quality, and more apt to be put into application. In addition, existing methods of dialogue have built-in limitations in that they typically draw from the predominant thinking patterns which focus in some areas but ignore others. This can result in clarity but a lack of comprehensiveness. This paper presents a Perspective Awareness Model which helps groups such as partnering teams, interagency teams, steering committees, and working groups elicit a wide net of perspectives and viewpoints. The paper begins by describing five factors that makes cooperation among such groups challenging. Next, a Perspective Awareness Model that makes it possible to manage these five factors is presented. The two primary components of this model --- the eight 'Thinking Directions' and the 'Shared Documentation' --- are described in detail. Several examples are given to illustrate how the Perspective Awareness Model can be used to elicit multiple perspectives to formulate high quality decisions in the area of environmental remediation and radioactive waste management.

    2016-01-01

    There has been an increasing trend in the use of contralateral prophylactic mastectomy (CPM) in the United States among women diagnosed with unilateral breast cancer, particularly young women. Approximately one-third of women <40 years old are undergoing CPM in the US. Most studies have shown that the CPM trend is mainly patient-driven, which reflects a changing environment for newly diagnosed breast cancer patients. The most common reason that women choose CPM is based on misperceptions about CPM's effect on survival and overestimation of their contralateral breast cancer (CBC) risk. No prospective studies have shown survival benefit to CPM, and the CBC rate for most women is low at 10 years. Fear of recurrence is also a big driver of CPM decisions. Nonetheless, studies have shown that women are mostly satisfied with undergoing CPM, but complications and subsequent surgeries with reconstruction have been associated with dissatisfaction with CPM. Studies on surgeon's perspectives on CPM are sparse but show that the most common reasons surgeons discuss CPM with patients is because of a suspicious family history or for a patient who is a confirmed BRCA mutation carrier. Studies on the cost-effectiveness of CPM have been conflicting and are highly dependent on patient's quality of life after CPM. Most recent guidelines for CPM are contradictory. Future areas of research include the development of interventions to better inform patients about CPM, modification of the guidelines to form a more consistent statement, longer term studies on CBC risk and CPM's effect on survival, and prospective studies that track the psychosocial effects of CPM on body image and sexuality.

  11. Protist taxonomy: an ecological perspective.

    PubMed Central

    Finlay, Bland J

    2004-01-01

    This is an exploration of contemporary protist taxonomy within an ecological perspective. As it currently stands, the 'morphospecies' does not accommodate the information that might support a truly ecological species concept for the protists. But the 'morphospecies' is merely a first step in erecting a taxonomy of the protists, and it is expected to become more meaningful in the light of genetic, physiological and ecological research in the near future. One possible way forward lies in the recognition that sexual and asexual protists may all be subject to forces of cohesion that result in (DNA) sequence-similarity clusters. A starting point would then be the detection of 'ecotypes'--where genotypic and phenotypic clusters correspond; but for that we need better information regarding the extent of clonality in protists, and better characterization of ecological niches and their boundaries. There is some progress with respect to the latter. Using the example of a community of ciliated protozoa living in the stratified water column of a freshwater pond, it is shown to be possible to gauge the potential of protists to partition their local environment into ecological niches. Around 40 morphospecies can coexist in the superimposed water layers, which presumably represent different ecological niches, but we have yet to discover if these are discrete or continuously variable. It is a myth that taxonomic problems are more severe for protists than for animals and plants. Most of the fundamental problems associated with species concepts (e.g. asexuals, sibling species, phenotypic variation) are distributed across biota in general. The recent history of the status of Pfiesteria provides a model example of an integrated approach to solving what are essentially taxonomic problems. PMID:15253347

  12. Fuel cells: A utilities perspective

    NASA Astrophysics Data System (ADS)

    Hessenius, Chris A.; Ang, Amos; Hamilton, Stephanie

    Southern California Edison (SCE) is actively assessing how to maximize the benefits from fuel cell power systems and other distributed generation (DG) technologies deployed along existing distribution level circuits. From a utility perspective, the viability of DG fuel cell systems increase as the technology matures and more "value-added" features are incorporated. As the number of DG projects grows in SCE's service territory and optimism increases about the potential uses, so does the need to better understand the impact wide-scale deployment may have on the performance of California's energy system. Understanding how DG technologies affect distribution level circuits and devising effective deployment strategies is essential for the technology to gain widespread acceptance and become an integral part of SCE's Transmission and Distribution (T&D) system planning. Simulation results are presented in this paper that indicate fuel cell systems combined with electronically switched power inverters capable or providing reactive power (a.k.a. VAR) support are more advantageous than fuel cell systems without such inverter features. In fact, for the SCE circuit analyzed, a strategically placed 2.5 MW fuel cell system with VAR support capabilities has a greater affect on circuit performance than a 3 MW fuel cell system without VAR support. Even though the 2.5 MW fuel cell system with VAR support inverter possesses 16.7% less power rating than the 3 MW system without VAR support, it was more effective in reducing circuit current flows, reducing distribution line losses, and maintaining circuit voltage within ±5% of 12.47 kilovolts (kV).

  13. Bright perspectives for nuclear photonics

    NASA Astrophysics Data System (ADS)

    Thirolf, P. G.; Habs, D.

    2014-05-01

    With the advent of new high-power, short-pulse laser facilities in combination with novel technologies for the production of highly brilliant, intense γ beams (like, e.g., Extreme Light Infrastructure - Nuclear Physics (ELI-NP) in Bucharest, MEGaRay in Livermore or a planned upgrade of the HIγS facility at Duke University), unprecedented perspectives will open up in the coming years for photonuclear physics both in basic sciences as in various fields of applications. Ultra-high sensitivity will be enabled by an envisaged increase of the γ-beam spectral density from the presently typical 102γ/eVs to about 104γ/eVs, thus enabling a new quality of nuclear photonics [1], assisted by new γ-optical elements [2]. Photonuclear reactions with highly brilliant γ beams will allow to produce radioisotopes for nuclear medicine with much higher specific activity and/or more economically than with conventional methods. This will open the door for completely new clinical applications of radioisotopes [3]. The isotopic, state-selective sensitivity of the well-established technique of nuclear resonance fluorescence (NRF) will be boosted by the drastically reduced energy bandwidth (<0.1%) of the novel γ beams. Together with a much higher intensity of these beams, this will pave the road towards a γ-beam based non-invasive tomography and microscopy, assisting the management of nuclear materials, such as radioactive waste management, the detection of nuclear fissile material in the recycling process or the detection of clandestine fissile materials. Moreover, also secondary sources like low-energy, pulsed, polarized neutron beams of high intensity and high brilliance [4] or a new type of positron source with significantly increased brilliance, for the first time fully polarized [5], can be realized and lead to new applications in solid state physics or material sciences.

    2016-01-01

    There has been an increasing trend in the use of contralateral prophylactic mastectomy (CPM) in the United States among women diagnosed with unilateral breast cancer, particularly young women. Approximately one-third of women <40 years old are undergoing CPM in the US. Most studies have shown that the CPM trend is mainly patient-driven, which reflects a changing environment for newly diagnosed breast cancer patients. The most common reason that women choose CPM is based on misperceptions about CPM’s effect on survival and overestimation of their contralateral breast cancer (CBC) risk. No prospective studies have shown survival benefit to CPM, and the CBC rate for most women is low at 10 years. Fear of recurrence is also a big driver of CPM decisions. Nonetheless, studies have shown that women are mostly satisfied with undergoing CPM, but complications and subsequent surgeries with reconstruction have been associated with dissatisfaction with CPM. Studies on surgeon’s perspectives on CPM are sparse but show that the most common reasons surgeons discuss CPM with patients is because of a suspicious family history or for a patient who is a confirmed BRCA mutation carrier. Studies on the cost–effectiveness of CPM have been conflicting and are highly dependent on patient’s quality of life after CPM. Most recent guidelines for CPM are contradictory. Future areas of research include the development of interventions to better inform patients about CPM, modification of the guidelines to form a more consistent statement, longer term studies on CBC risk and CPM’s effect on survival, and prospective studies that track the psychosocial effects of CPM on body image and sexuality.

  15. Adapting perspectives to facilitate knowledge assimilation

    SciTech Connect

    Kelsey, R.L.; Webster, R.B.

    1998-12-31

    The notion of perspective when supported in knowledge representation can allow the representation of multiple and varying points of view, some of which may even be inconsistent with one another. In an object-based knowledge representation methodology created and used by the authors, a perspective is defined by consolidating a number of objects and a number of those objects` associated attributes and methods into a view. This view can help partition a knowledge domain into separate portions. A separate portion represents an individual`s view of the knowledge domain. Representation of multiple and varying perspectives may add to the existing knowledge as well as reveal paths to additional knowledge. A simple example is presented where perspectives are used to represent game playing strategies and levels of expertise in those strategies. Players` perspectives are adapted and changed to provide additional knowledge and insight into further game playing strategies. Results show improvement in the playing of the games. Additionally, a more complex problem for applying these techniques is introduced.

    2013-04-01

    Time perspective is a cultural behavioral concept that reflects individuals' orientations or attitudes toward the past, present, or future. Individuals' time perspectives influence their choices regarding daily activities. Time perspective is an important consideration when teaching adolescents about the importance of being physically active. However, little is known about the relationship between time perspective and physical activity among adolescents. The purpose of this study was to determine the time perspective of central Appalachian adolescents and explore the relationship between time perspective and physical activity. This study was guided by The theory of planned behavior (TPB). One hundred and ninety-three students completed surveys to examine time perspective and physical activity behaviors. Data were collected in one school. Results of this study can inform school nurses and high school guidance counselors about the importance of promoting a future-oriented time perspective to improve physical activity and educational outcomes.

    2016-02-01

    A growing number of authors have argued that humans automatically compute the visual perspective of other individuals. Evidence for this has come from the dot perspective task in which observers are faster to judge the number of dots in a display when a human avatar has the same perspective as the observer compared to when their perspectives are different. The present experiment examined the 'spontaneous perspective taking' claim using a variant of the dot perspective paradigm in which we manipulated what the avatar could see via physical barriers that either allowed the targets to be seen by the avatar or occluded this view. We found a robust 'perspective taking' effect despite the avatar being unable to see the same stimuli as the participant. These findings do not support the notion that humans spontaneously take the perspective of others.

    2013-01-01

    Four perspectives on motor control provide the framework for developing a comprehensive theory of motor control in biological systems. The four perspectives, of decreasing orthodoxy, are distinguished by their sources of inspiration: neuroanatomy, robotics, self-organization, and ecological realities. Twelve major issues that commonly constrain (either explicitly or implicitly) the understanding of the control and coordination of movement are identified and evaluated within the framework of the four perspectives. The issues are as follows: (1) Is control strictly neural? (2) Is there a divide between planning and execution? (3) Does control entail a frequently involved knowledgeable executive? (4) Do analytical internal models mediate control? (5) Is anticipation necessarily model dependent? (6) Are movements preassembled? (7) Are the participating components context independent? (8) Is force transmission strictly myotendinous? (9) Is afference a matter of local linear signaling? (10) Is neural noise an impediment? (11) Do standard variables (of mechanics and physiology) suffice? (12) Is the organization of control hierarchical? PMID:19227497

  3. Social constructivist perspectives on teaching and learning.

    PubMed

    Palincsar, A S

    1998-01-01

    Social constructivist perspectives focus on the interdependence of social and individual processes in the co-construction of knowledge. After the impetus for understanding the influence of social and cultural factors on cognition is reviewed, mechanisms hypothesized to account for learning from this perspective are identified, drawing from Piagetian and Vygotskian accounts. The empirical research reviewed illustrates (a) the application of institutional analyses to investigate schooling as a cultural process, (b) the application of interpersonal analyses to examine how interactions promote cognition and learning, and (c) discursive analyses examining and manipulating the patterns and opportunities in instructional conversation. The review concludes with a discussion of the application of this perspective to selected contemporary issues, including: acquiring expertise across domains, assessment, educational equity, and educational reform.

  4. Challenges and perspectives in quantitative NMR.

    PubMed

    Giraudeau, Patrick

    2017-01-01

    This perspective article summarizes, from the author's point of view at the beginning of 2016, the major challenges and perspectives in the field of quantitative NMR. The key concepts in quantitative NMR are first summarized; then, the most recent evolutions in terms of resolution and sensitivity are discussed, as well as some potential future research directions in this field. A particular focus is made on methodologies capable of boosting the resolution and sensitivity of quantitative NMR, which could open application perspectives in fields where the sample complexity and the analyte concentrations are particularly challenging. These include multi-dimensional quantitative NMR and hyperpolarization techniques such as para-hydrogen-induced polarization or dynamic nuclear polarization. Because quantitative NMR cannot be dissociated from the key concepts of analytical chemistry, i.e. trueness and precision, the methodological developments are systematically described together with their level of analytical performance.

    Alexandrov, Natalia M.; Lewis, Robert Michael

    2000-01-01

    This work is concerned with an approach to formulating the multidisciplinary optimization (MDO) problem that reflects an algorithmic perspective on MDO problem solution. The algorithmic perspective focuses on formulating the problem in light of the abilities and inabilities of optimization algorithms, so that the resulting nonlinear programming problem can be solved reliably and efficiently by conventional optimization techniques. We propose a modular approach to formulating MDO problems that takes advantage of the problem structure, maximizes the autonomy of implementation, and allows for multiple easily interchangeable problem statements to be used depending on the available resources and the characteristics of the application problem.

    2015-01-01

    To date, there has been a lack of consensus among researchers, practitioners, and laypersons about the definition of cyberbullying. Researchers have typically applied the key characteristics of intent to harm, power imbalance, and repetition from the definition of traditional bullying to cyberbullying, but how these characteristics transfer from the real world to a technology-mediated environment remains ambiguous. Moreover, very few studies have specifically investigated how cyberbullying is defined from the perspective of bullies, victims and bystanders. To this end, this article will propose a three-part definition of cyberbullying, which incorporates the perspective of bullies, victims and bystanders.

    2017-03-01

    Since the early 2000s, numerous publications have presented major scientific opportunities that can be achieved through integrating insights from the area of nanotech into biotech (nanobiotech). This paper aims to explore the economic significance that nanobiotech has gained in the established pharmaceutical industry (big pharma). The empirical investigation draws on patent data as well as product revenue data; and to put the results into perspective, the amounts are compared with the established/traditional biotech sector. The results indicate that the new technology still plays only a minor role - at least from a commercial perspective.

  10. Mt. Pinatubo, Phillippines - Perspective View

    NASA Technical Reports Server (NTRS)

    1996-01-01

    The effects of the June 15, 1991, eruption of Mt. Pinatubo continue to affect the lives of people living near the volcano on the island of Luzon in the Philippines. The eruption produced a large amount of volcanic debris that was deposited on the flanks of the volcano as part of pyroclastic flows. This perspective view looking toward the east shows the western flank of the volcano where most of these pyroclastic flows were deposited.

    This debris consists of ash and boulders that mix with water after heavy rains to form volcanic mudflows called lahars. Lahars are moving rivers of concrete slurry that are highly erosive. They can sweep down existing river valleys, carving deep canyons where the slopes are steep, or depositing a mixture of fine ash and larger rocks on the gentler slopes. The deposits left from a lahar soon solidify into a material similar to concrete, but while they are moving, lahars are dynamic features, and in a single river valley the active channel may change locations within a few minutes or hours. These changes represent a significant natural hazard to local communities.

    The topographic data were collected by NASA's airborne imaging radar AIRSAR instrument on November 29, 1996. Colors are from the French SPOT satellite imaging data in both visible and infrared wavelengths collected in February 1996. Areas of vegetation appear red and areas without vegetation appear light blue. River valleys radiate out from the summit of the volcano (upper center). Since the eruption, lahars have stripped these valleys of any vegetation. The Pasig-Potrero River flows to the northeast off the summit in the upper right of the image.

    Scientists have been using airborne radar data collected by the AIRSAR instrument in their studies of the aftereffects of the Mt. Pinatubo eruption. AIRSAR collected imaging radar data over the volcano during a mission to the Pacific Rim region in late 1996 and on a follow-up mission to the area in late 2000. These data sets

  11. Obesity: thermodynamic principles in perspective.

    PubMed

    Rampone, A J; Reynolds, P J

    1988-01-01

    The energy balance equation applicable to all living organisms was used as a framework on which to construct a critical review of some of the more controversial aspects of the obesity problem. The equation matches energy intake against all the known forms of work that the body does in utilizing that energy, including external and internal work and the work of adipose tissue synthesis (stored energy). Equations representing everyday living conditions, resting, fasting and basal conditions were constructed. The equation applicable to everyday living (working, non-fasting) was used to develop a set of model paradigms to illustrate some of the devices that can be invoked to decrease expenditure and conserve energy. These served as models of how obesity can arise in the absence of calorie overconsumption. The same equation was then used to create a set of opposite paradigms showing how obesity can be prevented by increasing expenditure to waste energy and stabilize body weight when challenged by hyperphagia. In order to see caloric intake and the various work terms in their proper quantitative relationships it was necessary to assign numerical values to the equation. These were selected from published reports of caloric values representative of a non-obese adult of average size engaged in a typical white collar occupation. It was then easy to adjust these assigned values commensurate with the objectives described in the preceding paragraph. Since obesity research is hampered by a confusing array of metabolic interactions it was essential to alter only one of the energy terms at a time, excluding all metabolic interactions except for those unavoidable ones dictated by the laws of thermodynamics. Only in this way could we see the body's multiple energy forms in clear perspective with regard to their real quantitative significance in the energy balance sheet and their potential impact on body weight. Creating these models gave us the added advantage of enabling us better

    2000-01-01

    This perspective view shows the western part of the city of Pasadena, California, looking north towards the San Gabriel Mountains. Portions of the cities of Altadena and La Canada, Flintridge are also shown. The image was created from three datasets: the Shuttle Radar Topography Mission (SRTM) supplied the elevation data; Landsat data from November 11, 1986 provided the land surface color (not the sky) and U.S. Geological Survey digital aerial photography provides the image detail. The Rose Bowl, surrounded by a golf course, is the circular feature at the bottom center of the image. The Jet Propulsion Laboratory is the cluster of large buildings north of the Rose Bowl at the base of the mountains. A large landfill, Scholl Canyon, is the smooth area in the lower left corner of the scene. This image shows the power of combining data from different sources to create planning tools to study problems that affect large urban areas. In addition to the well-known earthquake hazards, Southern California is affected by a natural cycle of fire and mudflows. Wildfires strip the mountains of vegetation, increasing the hazards from flooding and mudflows for several years afterwards. Data such as shown on this image can be used to predict both how wildfires will spread over the terrain and also how mudflows will be channeled down the canyons. The Shuttle Radar Topography Mission (SRTM), launched on February 11, 2000, uses 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. The mission 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, an additional C-band imaging antenna and improved tracking and navigation devices. The mission is a cooperative project between the National Aeronautics and Space Administration (NASA), the National Imagery and Mapping Agency

  19. Taking someone else's spatial perspective: Natural stance or effortful decentring?

    PubMed

    Arnold, Gabriel; Spence, Charles; Auvray, Malika

    2016-03-01

    When perceiving stimuli, self-centred and decentred perspectives can be adopted. In the present study, we investigate whether perceivers have a natural perspective that constrains their spatial perception, with some people perceiving better with self-centred than decentred perspectives and vice versa for other people. We used a recognition task of tactile ambiguous letters (b, d, p, and q) presented on the stomach, for which three perspectives can be adopted (trunk-centred, head-centred, and decentred). At first, the participants were free to adopt any perspective they wanted. Then, either the same or a different perspective was imposed on them. Without constraints, 80% of the participants adopted a self-centred perspective (50% trunk-centred, 30% head-centred) and 20% a decentred one. The perspective adopted freely appears to be natural as recognition performance decreases with a different perspective and returns to its previous high level with the same perspective. Thus, to perceive space, some perceivers adopt naturally a perspective centred on themselves whereas others take naturally others' perspective.

  1. Eye tracking reveals the cost of switching between self and other perspectives in a visual perspective-taking task.

    PubMed

    Ferguson, Heather J; Apperly, Ian; Cane, James E

    2017-08-01

    Previous studies have shown that while people can rapidly and accurately compute their own and other people's visual perspectives, they experience difficulty ignoring the irrelevant perspective when the two perspectives differ. We used the "avatar" perspective-taking task to examine the mechanisms that underlie these egocentric (i.e., interference from their own perspective) and altercentric (i.e., interference from the other person's perspective) tendencies. Participants were eye-tracked as they verified the number of discs in a visual scene according to either their own or an on-screen avatar's perspective. Crucially in some trials the two perspectives were inconsistent (i.e., each saw a different number of discs), while in others they were consistent. To examine the effect of perspective switching, performance was compared for trials that were preceded with the same versus a different perspective cue. We found that altercentric interference can be reduced or eliminated when participants stick with their own perspective across consecutive trials. Our eye-tracking analyses revealed distinct fixation patterns for self and other perspective taking, suggesting that consistency effects in this paradigm are driven by implicit mentalizing of what others can see, and not automatic directional cues from the avatar.

  4. Migration and Development: A Theoretical Perspective 1

    PubMed Central

    De Haas, Hein

    2010-01-01

    The debate on migration and development has swung back and forth like a pendulum, from developmentalist optimism in the 1950s and 1960s, to neo‐Marxist pessimism over the 1970s and 1980s, towards more optimistic views in the 1990s and 2000s. This paper argues how such discursive shifts in the migration and development debate should be primarily seen as part of more general paradigm shifts in social and development theory. However, the classical opposition between pessimistic and optimistic views is challenged by empirical evidence pointing to the heterogeneity of migration impacts. By integrating and amending insights from the new economics of labor migration, livelihood perspectives in development studies and transnational perspectives in migration studies – which share several though as yet unobserved conceptual parallels – this paper elaborates the contours of a conceptual framework that simultaneously integrates agency and structure perspectives and is therefore able to account for the heterogeneous nature of migration‐development interactions. The resulting perspective reveals the naivety of recent views celebrating migration as self‐help development “from below”. These views are largely ideologically driven and shift the attention away from structural constraints and the vital role of states in shaping favorable conditions for positive development impacts of migration to occur.

  15. Equidistant Intervals in Perspective Photographs and Paintings

    PubMed Central

    2016-01-01

    Human vision is extremely sensitive to equidistance of spatial intervals in the frontal plane. Thresholds for spatial equidistance have been extensively measured in bisecting tasks. Despite the vast number of studies, the informational basis for equidistance perception is unknown. There are three possible sources of information for spatial equidistance in pictures, namely, distances in the picture plane, in physical space, and visual space. For each source, equidistant intervals were computed for perspective photographs of walls and canals. Intervals appear equidistant if equidistance is defined in visual space. Equidistance was further investigated in paintings of perspective scenes. In appraisals of the perspective skill of painters, emphasis has been on accurate use of vanishing points. The current study investigated the skill of painters to depict equidistant intervals. Depicted rows of equidistant columns, tiles, tapestries, or trees were analyzed in 30 paintings and engravings. Computational analysis shows that from the middle ages until now, artists either represented equidistance in physical space or in a visual space of very limited depth. Among the painters and engravers who depict equidistance in a highly nonveridical visual space are renowned experts of linear perspective. PMID:27698983

  20. Quantitation of dialysis: historical perspective.

    PubMed

    Shinaberger, J H

    2001-01-01

    This article is an attempt to provide a historical perspective to the ongoing attempts to quantify dialysis therapy. It is immediately apparent that motivated chemists, physicists, engineers, mathematicians, and other scientists from all over the world have greatly aided this effort. Dialysis, described by Graham in 1861, was furthered by Abel et al. and Hass before World War I. Willem Kolff attempted to evaluate mass removed and Alwall used a solute extraction ratio. However, the concept of "clearance" and "dialysance" awaited the studies of Wolf et al. in 1951. This classic work describes most of the information concerning actual dialyzer performance known today. A. S. Michaels provided the equations leading to the KoA/Ro/A concept in 1966 which only very recently required updating. The interaction of diffusion and convection is complex and was studied by Villarroel in 1977 and recently by Jaffrin. L. W. Henderson studied and described hemofiltration and hemodiafiltration from 1967-1975. Efforts to relate the patient's outcome to the dialyzer's performance have been difficult and ongoing since 1971; the Babb-Scribner Square meter-hour (which included the expression "Kt/V"); the Kopp et al. Liter-Kilogram concept; 1972 Kjellstrand clearance * time/kg or Liter. A NIH sponsored conference on the Adequacy of Dialysis in Monterey, California in March of 1974 was focused somewhat on the "middle molecule" theory of uremic toxicity, but contained a presentation by Sargent and Gotch on the possibilities of urea kinetic modeling. They developed iterative computer programs to obtain the best estimates of the required variables. At about this same time, Teschan, Ginn et al. published a series of neurofunctional tests and EEG power spectra analyses which most convincingly showed that dialysis two times a week was inadequate, and that dialysis delivered three times a week at urea clearance equal to body water volume was required to normalize these abnormalities: a major

  1. Patients' perspectives on antidepressant treatment in consultations with physicians.

    PubMed

    Fosgerau, Christina Fogtmann; Davidsen, Annette Sofie

    2014-05-01

    Patient perspectives on antidepressant treatment and physician attention, and responses toward these in consultations with patients diagnosed with depression, are rarely studied. We analyzed video-recorded consultations with general practitioners (GPs) and psychiatrists. We used conversation analysis and systemic functional linguistics and found that the perspectives patients expressed related to the possibility of achieving, and the inability to retain, a sense of agency. Patients also presented indirect expressions of shame and expressions suggesting alienation toward medical treatment. GPs attended to patient perspectives by talking about medication indirectly. When patients expressed their perspectives, GPs responded by being nonauthoritative but also without prompting patients to elaborate on their reflections. Psychiatrists responded authoritatively and never urged patients to reflect on their perspectives. Shared decision making did not take place because physicians did not explore patients' perspectives in depth or offer their expertise by taking these perspectives into consideration.

  2. Perspective-Taking Increases Willingness to Engage in Intergroup Contact

    PubMed Central

    Wang, Cynthia S.; Kenneth, Tai; Ku, Gillian; Galinsky, Adam D.

    2014-01-01

    The current research explored whether perspective-taking increases willingness to engage in contact with stereotyped outgroup members. Across three studies, we find that perspective-taking increases willingness to engage in contact with negatively-stereotyped targets. In Study 1, perspective-takers sat closer to, whereas stereotype suppressors sat further from, a hooligan compared to control participants. In Study 2, individual differences in perspective-taking tendencies predicted individuals' willingness to engage in contact with a hooligan, having effects above and beyond those of empathic concern. Finally, Study 3 demonstrated that perspective-taking's effects on intergroup contact extend to the target's group (i.e., another homeless man), but not to other outgroups (i.e., a man of African descent). Consistent with other perspective-taking research, our findings show that perspective-taking facilitates the creation of social bonds by increasing contact with stereotyped outgroup members.

  3. An Intention-Based Account of Perspective-Taking: Why Perspective-Taking Can Both Decrease and Increase Moral Condemnation.

    PubMed

    Lucas, Brian J; Galinksy, Adam D; Murnighan, Keith J

    2016-09-20

    Perspective-taking often increases generosity in behavior and attributions. We present an intentions-based account to explain how perspective-taking can both decrease and increase moral condemnation. Consistent with past research, we predicted perspective-taking would reduce condemnation when the perspective-taker initially attributed benevolent intent to a transgressor. However, we predicted perspective-taking would increase condemnation when malevolent intentions were initially attributed to the wrongdoer. We propose that perspective-taking amplifies the intentions initially attributed to a transgressor. Three studies measured and manipulated intention attributions and found that perspective-taking increased condemnation when malevolent intentions were initially attributed to a transgressor. Perspective-taking also increased costly punishment of a transgressor, an effect mediated by malevolent intentions. In contrast, empathy did not increase punitive responses, supporting its conceptual distinction from perspective-taking. Whether perspective-taking leads to forgiveness or condemnation depends on the intentions the perspective-taker initially attributes to a transgressor.

  4. The extent of visual space inferred from perspective angles.

    PubMed

    Erkelens, Casper J

    2015-01-01

    Retinal images are perspective projections of the visual environment. Perspective projections do not explain why we perceive perspective in 3-D space. Analysis of underlying spatial transformations shows that visual space is a perspective transformation of physical space if parallel lines in physical space vanish at finite distance in visual space. Perspective angles, i.e., the angle perceived between parallel lines in physical space, were estimated for rails of a straight railway track. Perspective angles were also estimated from pictures taken from the same point of view. Perspective angles between rails ranged from 27% to 83% of their angular size in the retinal image. Perspective angles prescribe the distance of vanishing points of visual space. All computed distances were shorter than 6 m. The shallow depth of a hypothetical space inferred from perspective angles does not match the depth of visual space, as it is perceived. Incongruity between the perceived shape of a railway line on the one hand and the experienced ratio between width and length of the line on the other hand is huge, but apparently so unobtrusive that it has remained unnoticed. The incompatibility between perspective angles and perceived distances casts doubt on evidence for a curved visual space that has been presented in the literature and was obtained from combining judgments of distances and angles with physical positions.

  6. Long-Term Perspectives on Interstellar Flight

    NASA Astrophysics Data System (ADS)

    Michaud, M. A. G.

    Realizing interstellar travel by machines or living beings will require not only scientific and technological progress, but also a shared secular belief among a determined minority that this enterprise is important for the human future. Their efforts may have to extend beyond individual human lifetimes. Historical perspectives, on both the past and the future, are proposed. Interstellar probes could be a more thorough way of searching for alien forms of life and intelligence in nearby systems, particularly if there were intelligent beings there who did not employ technologies our astronomical observing devices can detect from here. Perspectives on the ethical, policy, and design issues of such close encounters with alien life and intelligence are presented. Ways of accelerating the coming of interstellar probes are suggested.

    Shared Perspectives, one of the technologies within the PNNL-developed GridOPTICS capability suite, enables neighboring organizations, such as different electric utilities, to more effectively partner to solve outages and other grid problems. Shared Perspectives provides a means for organizations to safely stream information from different organizational service areas; the technology then combines and aligns this information into a common, global view, enhancing global situation awareness that can reduce the time it takes to talk through a problem and identify solutions. The technology potentially offers applications in other areas, such as disaster response; collaboration in the monitoring/assessment of real-time events (e.g., hurricanes, earthquakes, and tornadoes); as well as military uses.

  8. Drug use and addiction: evolutionary perspective.

    PubMed

    Durrant, Russil; Adamson, Simon; Todd, Fraser; Sellman, Doug

    2009-11-01

    Drug use creates a significant amount of harm in modern societies. From an evolutionary perspective, the pervasive use of drugs and the ongoing risk of drug addiction can be explained in terms of the action of drugs on evolved motivational-emotional systems. Addiction arises through interaction of these evolutionarily ancient systems, designed to promote the pursuit of natural rewards, and contemporary environments where purified and potent forms of drugs are readily available. This evolutionary analysis is extended to account for developmental patterns in problem drug use, and to explain the existence of behavioural addictions, such as problem gambling. The paper concludes by considering some of the clinical and public policy implications of the evolutionary perspective presented.

Sources of information for this review include the scientific literature, regulatory and government documents, pro-nuclear and anti-nuclear publications, and news media articles. In examining the sources of information, it has become evident that a major distinction can be made between the optimistic or positive viewpoints, and the pessimistic or negative ones. Consequently, these form the principal categories for presentation of the perspectives on the radioactive waste management problem have been further classified as relating to the following issue areas: the physical aspects of radiation, longevity, radiotoxicity, the quantity of radioactive wastes, and perceptual factors.

  10. A different perspective: introducing positive criminology.

    PubMed

    Ronel, Natti; Elisha, Ety

    2011-04-01

    Positive criminology is a new conceptual perspective of criminology, encompassing several theories and models. Positive criminology refers to a focus on individuals' encounters with forces and influences that are experienced as positive, which distance them from deviance and crime, whether by means of formal and informal therapy programs and interventions, such as self-help groups; through emphasis of positive social elements, such as exposure to goodness, social acceptance, and reintegrative shaming; or based on positive personal traits, such as resilience and coherence. The perspective of positive criminology broadens that of traditional criminology, which focuses mainly on understanding the factors and processes that lead individuals and groups to what is defined as deviant and criminal behavior. Positive criminology is implemented in treatment and rehabilitation of individuals and groups that have demonstrated deviant and criminal behavior, by emphasizing positive experiences that may potentially prevent or discourage continued criminal behavior. Positive criminology is also expressed in prevention based on a positive approach.

    Current industry perspective of how discovery is conducted seems to be fragmented and does not have a unified overall outlook of how discovery challenges are being addressed. Consequently, well-defined processes and drug-likeness criteria are being viewed as "broken" and will not maintain future R&D productivity. In this commentary, an analysis of existing practices for defining successful development candidates resulted in a 5 "must do" list to help advance Drug Discovery as presented from a Pharmaceutics perspective. The 5 "must do" list includes: what an ideal discovery team model should look like, what criteria should be considered for the desired development candidate profile, what the building blocks of the development candidate should look like, and how to assess the development risks of the candidate.

    This review is intended to reflect upon the current status and perspectives of cell-based immunotherapy at a time when the promise of extensive pre-clinical research has been translated into encouraging clinical responses. However, some of these have also been complicated by significant adverse reactions. As the field moves towards definitive late stage trials, with a growing interest from pharmaceutical companies, we realize that novel cell therapy strategies pose questions that are familiar to traditional drug development, along with new considerations due to the potential of T cells to persist long term and to expand after adoptive transfer. These questions address the safety of the product, the efficacy, the mode of action, and the anticipation of risks. From different perspectives, we intend to address exciting opportunities and safety concerns in current concepts of cellular immunotherapy. PMID:24629797

The “continuist” perspective seeks the evolutionary roots of complex human syntax in simpler combinatory systems used in animal communication systems, such as iteration and sequencing. The “exaptationist” perspective posits evolutionary change of function, so that systems today used for linguistic communication might previously have served quite different functions in earlier hominids. I argue that abundant biological evidence supports an exaptationist perspective, in general, and that it must be taken seriously when considering language evolution. When applied to syntax, this suggests that core computational components used today in language could have originally served non-linguistic functions such as motor control, non-verbal thought, or spatial reasoning. I outline three specific exaptationist hypotheses for spoken language. These three hypotheses each posit a change of functionality in a precursor circuit, and its transformation into a neural circuit or region specifically involved in language today. Hypothesis 1 suggests that the precursor mechanism for intentional vocal control, specifically direct cortical control over the larynx, was manual motor control subserved by the cortico-spinal tract. The second is that the arcuate fasciculus, which today connects syntactic and lexical regions, had its origin in intracortical connections subserving vocal imitation. The third is that the specialized components of Broca’s area, specifically BA 45, had their origins in non-linguistic motor control, and specifically hierarchical planning of action. I conclude by illustrating the importance of both homology (studied via primates) and convergence (typically analyzed in birds) for testing such evolutionary hypotheses. PMID

  11. Formalized Epistemology in a Philosophical Perspective

    NASA Astrophysics Data System (ADS)

    Barreau, Hervé

    The need for a formalized epistemology is recognized by all scholars who think that the relativity of all sciences must not be referred to a social relativism. In XXth century, Husserl was the protagonist of such an epistemic philosophy. But this philosophy was more successful in social and human sciences than in natural sciences. In this latter domain, quantum mechanics obeys the requirements of a Kantien perspective in a more precise sense that was the case with Newtonian mechanics.

    In this article the author develops a new perspective on the role and the position of the human body in the world of education. The interest in the theme of corporeality is far from new, and this applies not only to the field of social sciences in general (where in the last two decades a corporeal turn has taken place, see Sheets-Johnstone 2009),…

  13. Current and Future Perspectives in Craniosynostosis

    Craniosynostosis has a varied clinical spectrum, ranging from isolated single suture involvement to multi-sutural fusions. Greater understanding of the pathogenesis of craniosynostosis has led to the development of practical treatment protocols. Three stages of growth have determined the approach to managing craniosynostosis : the early period, up to 12 months; the intermediate period, from 1 to 10 years; and the late period, beginning at 10 years. This review discusses current surgical management and future perspectives in craniosynostosis. PMID:27226856

    Ebola virus disease (EVD) is a potentially fatal haemorrhagic disease of humans. The last and most serious outbreak of Ebola virus (EBOV) started in December 2013 in West Africa and also affected other continents. Animals such as fruit bats and non-human primates are potential sources of EBOV. This review highlights the clinical features of EVD in humans and animals and addresses the public health implications of EVD outbreaks from the veterinary perspective.

    The incidence of indoor air quality problems has increased dramatically over the past decade. Investigation of these problems has yielded a definitive cause in only one third of the cases. Psychosocial factors may play a key role in the development and propagation of symptoms attributed to poor indoor air quality. Guidelines for managing indoor air quality problems from the organizational perspective are based upon psychosocial principles and elements of risk perception.

    Pharmacovigilance aims to identify unknown adverse drug reactions once clinical development is complete, in order to promote improved use of drugs, and thus a reduction in risk for every exposed patient. We describe in this article the missions of French pharmacovigilance system, including French drug agency, Regional Centers of Pharmacovigilance, health professionals, pharmaceutical companies, patients and their associations. We also develop the French pharmacovigilance organization, its perspectives and challenges, both in French and European levels.

  19. Food sustainability: problems, perspectives and solutions.

    PubMed

    Garnett, Tara

    2013-02-01

    The global food system makes a significant contribution to climate changing greenhouse gas emissions with all stages in the supply chain, from agricultural production through processing, distribution, retailing, home food preparation and waste, playing a part. It also gives rise to other major environmental impacts, including biodiversity loss and water extraction and pollution. Policy makers are increasingly aware of the need to address these concerns, but at the same time they are faced with a growing burden of food security and nutrition-related problems, and tasked with ensuring that there is enough food to meet the needs of a growing global population. In short, more people need to be fed better, with less environmental impact. How might this be achieved? Broadly, three main 'takes' or perspectives, on the issues and their interactions, appear to be emerging. Depending on one's view point, the problem can be conceptualised as a production challenge, in which case there is a need to change how food is produced by improving the unit efficiency of food production; a consumption challenge, which requires changes to the dietary drivers that determine food production; or a socio-economic challenge, which requires changes in how the food system is governed. This paper considers these perspectives in turn, their implications for nutrition and climate change, and their strengths and weaknesses. Finally, an argument is made for a reorientation of policy thinking which uses the insights provided by all three perspectives, rather than, as is the situation today, privileging one over the other.

  20. Using Perspective to Model Complex Processes

    SciTech Connect

    Kelsey, R.L.; Bisset, K.R.

    1999-04-04

    The notion of perspective, when supported in an object-based knowledge representation, can facilitate better abstractions of reality for modeling and simulation. The object modeling of complex physical and chemical processes is made more difficult in part due to the poor abstractions of state and phase changes available in these models. The notion of perspective can be used to create different views to represent the different states of matter in a process. These techniques can lead to a more understandable model. Additionally, the ability to record the progress of a process from start to finish is problematic. It is desirable to have a historic record of the entire process, not just the end result of the process. A historic record should facilitate backtracking and re-start of a process at different points in time. The same representation structures and techniques can be used to create a sequence of process markers to represent a historic record. By using perspective, the sequence of markers can have multiple and varying views tailored for a particular user's context of interest.
