    Children's exposure to violence increases their risk for later victimisation and perpetration of intimate partner violence (IPV). However, the relative influence of child abuse, adolescent violence, peer approval of violence and pro-violence attitudes on later IPV is not well established. Analyses focus on the prediction of adult IPV from variables measured in childhood and adolescence to establish the unique influence of earlier victimisation and perpetration of violence, as well as other variables grounded in theory and empirical findings. Data are from a longitudinal study that began in the 1970s with a sample of 457 preschool-aged children who were reassessed as adults. Outcomes of adult IPV victimisation and perpetration types were regressed on predictors of parent-reported child abuse, officially recorded child maltreatment, adolescent victimisation, violence perpetration, pro-violence attitudes and peer approval of violence during adolescence, controlling for childhood Socio Economic Status (SES), age in adolescence and gender. Dating violence victimisation and peer approval of dating violence in adolescence emerged as the unique predictors of IPV victimisation and perpetration in adulthood. Official child maltreatment predicted IPV perpetration. Results underscore the importance of prevention programmes and strategies to disrupt the cycle of violence at its early stages, as well as interventions during adolescence targeting peer influences.

  3. Effects of playing violent videogames on Chinese adolescents' pro-violence attitudes, attitudes toward others, and aggressive behavior.

    Wei, Ran

    2007-06-01

    This study examines the effects of exposure to online videogame violence on Chinese adolescents' attitudes toward violence, empathy, and aggressive behavior. Results of bivariate analyses show that playing violent videogames on the Internet was associated with greater tolerance of violence, a lower emphatic attitude, and more aggressive behavior. Results of hierarchical regression analyses showed sustained relationships between exposure and pro-violent attitudes and empathy when exposure was examined simultaneously with gender, computer use, and Internet use. However, the linkage between exposure and aggression became non-significant, suggesting that the effects of playing violent videogames were greater for attitudinal outcomes than on overt behavior. Gender differences in playing videogames and in effects were also found.

    Full Text Available En este artículo se presenta la experiencia de los censos comunitarios contextualizada con la Ley de los Consejos Comunales de 2006, como una respuesta a la ausencia de información sociodemográfica sobre los barrios populares en Venezuela. Censos que intentan responder a la necesaria pregunta de cuántas personas habitan en el asentamiento, cómo se distribuyen por edades y por sexo, en cuántas viviendas, información que resulta fundamental, tanto para las instituciones como para las organizaciones de base, a la hora de asignar recursos. Pero, sobre esta información recolectada entre la comunidad y – en este caso – con el apoyo de la Escuela de Sociología de la Universidad Central de Venezuela, se presenta la interrogante sobre la calidad, la confiabilidad y la oportunidad de los datos recabados, y de la información generada. Este artículo recorre los pasos metodológicos seguidos en el Barrio Nuevo Horizonte del Distrito Capital, para la realización de veinte censos, desde la recabación de los datos hasta su procesamiento y difusión.

    Full Text Available La usabilidad es considerada uno de los factores más importantes dentro de la calidad de un producto de software. Debido a esto es de interés poder contar con metodologías para medir la usabilidad de las aplicaciones. Los métodos de análisis de usabilidad que actualmente se utilizan, métodos clásicos, fueron desarrollados para aplicaciones de escritorio. Con la aparición, el uso masivo y el crecimiento de los dispositivos móviles, especialmente los Smartphones, la medición de usabilidad en aplicaciones móviles se tornó un tema de investigación. Los métodos y métricas actualmente utilizados para medir usabilidad pueden no ser directamente aplicables a este tipo de productos. Los estudios de usabilidad se han efectuado sobre diferentes contextos, recientemente se empezó a considerar la usabilidad en un contexto móvil. Este trabajo examina los métodos y las métricas utilizados para medir usabilidad y pretende analizar que desafíos existen al momento de realizar pruebas de usabilidad en aplicaciones móviles, donde el contexto que cambia continuamente pasa a tener un rol preponderante.

    2011-01-01

    Full Text Available El automóvil como bien de consumo duradero se difunde en la América Latina en el primer tercio del siglo XX. El comercio exterior determina su consumo en la región, a excepción de algunos países que en el decenio de los veinte consiguen instrumentar plantas de ensamblaje de automóviles con piezas importadas, lo que ocurre solamente allí donde coincide una cierta dimensión del mercado con una renta alta (Argentina, Brasil, México y Uruguay. Otros factores explicativos, aun-que en un claro segundo plano, son la extensión de medidas proteccionistas y una mayor desigualdad en la distribución de la renta. Al respecto proponemos que hubo un efecto negativo en el consumo final cuando el consumo se sesgó hacia los automóviles de gama más cara; en tanto que en los países donde el consumo por habitante es alto se consumen cantidades proporcionalmente altas de vehículos de la gama de precios bajos. Las importaciones de automóviles muestran buena parte del consumo de automóviles y nos permiten calcular los vehículos en circulación, además de indicar cuales fueron los países en los que se desarrollaron experiencias propias en la producción de autos. El papel que en ellas desempeña los Estados Unidos es casi absoluto a partir de 1920, después de la primera Guerra Mundial, aunque anteriormente tiene que compartir buena parte del, aún reducido mercado, con varios países europeos (Francia, Italia, Alemania y Gran Bretaña.

    Full Text Available Resumen: En este trabajo se presenta una solución para mejorar el rendimiento de los robots móviles con ruedas que se desplacen sobre superficies con un bajo coeficiente de fricción estática. En estas circunstancias, los robots móviles con ruedas pueden experimentar pérdidas de tracción, y por tanto, sufrir deslizamientos a lo largo de la superficie. La solución descrita propone la utilización de una configuración especial para el robot móvil, en la que todas las ruedas son accionadas de forma independiente, y una estructura de control que consta de tres partes bien diferenciadas: un controlador de seguimiento con realimentación de estado basado en el modelo cinemático del robot, una extensión de la ley de control cinemático resultante para incorporar la dinámica del robot móvil utilizando backstepping, y un algoritmo de distribución de la fuerza de tracción global, que calcula las señales de referencia adecuadas para cada una de las ruedas. Con esta estructura se consigue controlar la posición y la velocidad del robot móvil, y al mismo tiempo, distribuir la fuerza de tracción global entre las ruedas, evitando así el deslizamiento del robot. El funcionamiento de los algoritmos de control es evaluado mediante pruebas experimentales. Abstract: This article presents a solution to improve the performance of wheeled mobile robots that move upon surfaces with small coefficient of static friction. In these circumstances the wheeled mobile robots can experience loss of traction and therefore, slide along the surface. The proposed solution implies the use of a special configuration for the mobile robot, in which all the wheels are driven independently, and a control structure which consists of three distinct parts: firstly, a state-feedback tracking controller based on the kinematic model of the mobile robot is derived. Secondly, an extension of the kinematic control law is made to incorporate the dynamics of the wheeled mobile

    Full Text Available   El impacto de las nuevas tecnologías en el periodismo se remonta a principios del siglo XXI, cuando la introducción de Internet en las redacciones trajo consigo cambios que afectaron a los procesos de producción, emisión y recepción de la información. La digitalización obligó a las redacciones a reestructurarse y a los periodistas a repensar nuevas estrategias de distribución de contenidos. Este fenómeno de mutaciones, conocido con el nombre de convergencia, se intensifica en la actualidad con la llegada de los dispositivos móviles en el panorama comunicativo. Los teléfonos permiten que la producción y el consumo de información se realice, por primera vez, en cualquier lugar y  mientras se está en movimiento.   La evolución tecnológica de las pequeñas pantallas situó a los dispositivos como una plataforma de gran importancia para la industria mediática. Nuestro objetivo es presentar las fortalezas, desafíos y debilidades del impacto de la telefonía móvil en el ámbito comunicativo.

    Full Text Available Este artículo presenta brevemente la teoría fundamental del Modelo Suzuki comúnmente usado para modelar la propagación en canales inalámbricos. El modelo toma en cuenta los efectos del sombreado y del multi-trayecto de manera simultánea. Además, se valida el modelo mediante una comparación estadística entre mediciones realizadas en el entorno real y simulaciones realizadas en MATLAB® a través de la generación de series de tiempo Suzuki distribuidas. Las mediciones se realizaron durante diez horas sobre la banda de frecuencias entre 850 MHz y 900 MHz. Con los datos obtenidos en medición durante los primeros cinco minutos, se caracterizó el canal inalámbrico para cada una de las frecuencias muestreadas calculando la media y desviación estándar de la señal recibida. Estos dos parámetros fueron introducidos como variables de entrada para la generación de las respectivas series de tiempo. Para cada frecuencia se realizaron simulaciones prediciendo los niveles de la señal que se obtendrían durante diez horas. Finalmente, se calculó el error cuadrático medio entre los valores medidos y los valores generados en simulación. Los resultados obtenidos demuestran que el modelo es válido como una herramienta de predicción de las características de propagación en comunicaciones móviles.

    Full Text Available El presente trabajo analiza el papel de los jóvenes consumidores en el contexto de los nuevos procesos comunicativos que surgen de tecnologías emergentes: el uso de las aplicaciones de marca en los dispositivos móviles. Éstos incorporan funcionalidades sociales y comunicativas cada vez más complejas y, entre ellas, las aplicaciones para teléfonos inteligentes que vinculan publicidad comercial y pagos forman un campo novedoso pero de interés prioritario para distintos actores comunicativos, como son las marcas comerciales, los servicios bancarios y las propias compañías tecnológicas. En ese contexto la presente investigación describe y codifica cualitativamente cómo los usuarios entienden, perciben y utilizan, como prosumidores, las aplicaciones de marca corporativa y los pagos. Para ello se aplican técnicas de investigación en cuatro grupos focales, de edades comprendidas entre los 18 y 24 años, compuestos por jóvenes universitarios españoles estudiantes en Comunicación, como usuarios que muestran una predisposición y una adopción temprana de estas prácticas. Las respuestas de las reuniones del grupo de discusión permitieron una clasificación de las prácticas comunicativas. En conclusión, se constata una alta predisposición de estos consumidores activos por interactuar con contenidos comerciales, estableciendo redes sociales bajo el amparo de una cultura e imagen de marca, como forma de cohesión grupal. Otros usos se relacionan con el entretenimiento y la información, al tiempo que aún se muestran reticentes al pago de productos o servicios mediante el dispositivo móvil.

Sin embargo, conseguir que los robots se muevan de forma eficiente y precisa en este tipo de entornos no es una tarea sencilla. Un primer aspecto crítico es el sistema de locomoción. En este caso, las orugas constituyen una alternativa sólida a otro tipo de sistemas y desde principios del siglo XX han demostrado sus bondades en vehículos tripulados. En este artículo se motiva y se demuestra mediante pruebas reales la idoneidad de este tipo de locomoción para robots móviles en terrenos no preparados. Es importante remarcar que este artículo pretende ser un resumen extendido del libro recientemente publicado por los autores “Autonomous Tracked Robots in Planar Off-Road Conditions” (González et al., 2014, y, por lo tanto, no pretende ser una contribución original. Inicialmente se presenta una perspectiva histórica de los vehículos y los robots con orugas. Posteriormente se discuten los aspectos de modelado con especial mención al fenomeno del deslizamiento. A continuación, se analizan varias estrategias de localización, en particular, la odometria visual. También se analiza el aspecto del control de navegación, para ello se analizan varias estrategias con compensación del deslizamiento.

Las razones de este hecho pueden residir tanto en problemas de selección adversa como de riesgo moral. Pero además de ello, en la ocurrencia de siniestros pueden intervenir otra serie de características, relativas a la póliza, al vehículo, o incluso al propio asegurado. En este trabajo se pretende determinar cuáles son estos factores, para cada grado de cobertura considerado, así como realizar un análisis comparativo entre los mismos para comprobar si coinciden o si, por el contrario, cada tipo de cobertura muestra sus propios factores o características determinantes de la siniestralidad.Para llevar a cabo este estudio, se utilizará información procedente de una entidad aseguradora privada española junto con un modelo de elección discreta binaria de tipo probit, donde la variable a explicar recogerá la ocurrencia o no de siniestros.

    2014-01-01

    To be habitable, a world (planet or moon) does not need to be located in the stellar habitable zone (HZ), and worlds in the HZ are not necessarily habitable. Here, we illustrate how tidal heating can render terrestrial or icy worlds habitable beyond the stellar HZ. Scientists have developed a language that neglects the possible existence of worlds that offer more benign environments to life than Earth does. We call these objects "superhabitable" and discuss in which contexts this term could be used, that is to say, which worlds tend to be more habitable than Earth. In an appendix, we show why the principle of mediocracy cannot be used to logically explain why Earth should be a particularly habitable planet or why other inhabited worlds should be Earth-like. Superhabitable worlds must be considered for future follow-up observations of signs of extraterrestrial life. Considering a range of physical effects, we conclude that they will tend to be slightly older and more massive than Earth and that their host stars will likely be K dwarfs. This makes Alpha Centauri B, which is a member of the closest stellar system to the Sun and is supposed to host an Earth-mass planet, an ideal target for searches for a superhabitable world.

    RESUMEN

    Los objetivos de la presente investigación fueron comprobar la efectividad de un programa de intervención para mejorar la habilidad de manejo de móviles en el alumnado de Primaria y validar un instrumento de evaluación cualitativo para conocer los niveles de dificultad. Se plantearon dos hipótesis de estudio: a el programa permite mejorar el grado de habilidad del alumnado y b la escala de tareas motrices es un instrumento adecuado para su evaluación.  Se trabajó con una muestra de 148 alumnos  de Primaria empleando un diseño pretest-postest con grupo de control, con dos observaciones post-tratamiento. Se utilizo una escala compuesta por 15 tareas para la evaluación de la habilidad de manejo de móviles. En la fase de tratamiento se aplicó un programa de intervención para la mejora de las habilidades objeto de estudio. Los resultados indicaron que la escala fue un instrumento adecuado para valorar el grado de dificultad de las tareas. Además se obtuvo un alto nivel de retención, en todas las tareas, respecto al grupo tratado, un mes después del tratamiento. La conclusión más relevante es que el programa de intervención se ofrece como una alternativa metodológica válida para mejorar dichas habilidades.
    Palabras Clave: programa, habilidades básicas, escala, primaria.

    Full Text Available The contaminant impact of cadmium, chromium, copper, nickel, lead and zinc on soils and vegetation in the surroundings of a scrapyard of discarded vehicles, taken at several distances of the contaminant source, is evaluated and compared with control samples free of contamination. The total metal contents of these elements in the soils and vegetation samples are determined by ICP-AES and their presence in soils is detected by particles analysis with SEM-EDXRA. The contents of the affected soils are remarkably higher than the ones of a control sample for the all elements and gradually decrease from the contaminant source. These contents in plants are also relevantly higher than the values of the control sample, and are especially high for the aereal parts. This remarkable contamination, moreover the great retention capacity of these soils, due to their edaphical characteristics, and the presence of a great quantity of not-mineral particles, may indicate that the probable access path of the metal contaminants to the plants could be the atmospherical dispersion of the particles generated by the scrapyard activities (burning and transformation of the vehicles scrap.

    Hugh Everett III presented pure wave mechanics, sometimes referred to as the many-worlds interpretation, as a solution to the quantum measurement problem. While pure wave mechanics is an objectively deterministic physical theory with no probabilities, Everett sought to show how the theory might be understood as making the standard quantum statistical predictions as appearances to observers who were themselves described by the theory. We will consider his argument and how it depends on a particular notion of branch typicality. We will also consider responses to Everett and the relationship between typicality and probability. The suggestion will be that pure wave mechanics requires a number of significant auxiliary assumptions in order to make anything like the standard quantum predictions.

    The traditional concept of terraforming assumes ready availability of candidate planets with acceptable qualities: orbiting a star in its "Goldilocks zone", liquid water, enough mass, years longer than days, magnetic field, etc. But even stipulating affordable interstellar travel, we still might never find a good candidate elsewhere. Whatever we found likely would require centuries of heavy terraforming, just as Mars or Venus would here. Our increasing appreciation of the ubiquity of life suggests that any terra nova would already possess it. We would then face the dilemma of introducing alien life forms (us, our microbes) into another living world. Instead, we propose a novel method to create habitable environments for humanity by enclosing airless, sterile, otherwise useless planets, moons, and even large asteroids within engineered shells, which avoids the conundrum. These shells are subject to two opposing internal stresses: compression due to the primary's gravity, and tension from atmospheric pressure contained inside. By careful design, these two cancel each other resulting in zero net shell stress. Beneath the shell an Earth-like environment could be created similar in almost all respects to that of Home, except for gravity, regardless of the distance to the sun or other star. Englobing a small planet, moon, or even a dwarf planet like Ceres, would require astronomical amounts of material (quadrillions of tons) and energy, plus a great deal of time. It would be a quantum leap in difficulty over building Dyson Dots or industrializing our solar system, perhaps comparable to a mission across interstellar space with a living crew within their lifetime. But when accomplished, these constructs would be complete (albeit small) worlds, not merely large habitats. They could be stable across historic timescales, possibly geologic. Each would contain a full, self-sustaining ecology, which might evolve in curious directions over time. This has interesting implications

    Full Text Available In recent years smart mobile devices have bolstered new interaction scenarios that require more sophisticated human-machine interfaces. The leading developers of operating systems for these devices now provide APIs (Application Programming Interface for developers to implement their own applications, including different solutions for developing graphical interfaces, control sensors and providing oral interaction. Despite the usefulness of these resources, defined strategies are still needed for developing multimodal interfaces to take greater advantage of these devices for identifying and meeting the needs of users. Currently, these applications are typically ad-hoc and facilitate oral communication only through simple commands. In this paper we propose the practical application of context-sensitive multimodal conversational agents to provide advanced library services that dynamically consider specific user needs and preferences, as well as the specific characteristics of the environment in which the interaction occurs. Such agents would improve and customize the service provided by a mobile device with Internet access. Our proposal integrates features of Android APIs on a modular architecture emphasizing the management of interactions and context awareness in order to create robust applications that can be easily updated and adapted to the user.Los dispositivos móviles inteligentes han fomentado en los últimos años nuevos escenarios de interacción que requieren interfaces persona-máquina más sofisticados.

El propósito de la intervención fue desarrollar la capacidad, mejorar los conocimientos y habilidades para realizar actividades de educación e información continuas que generen percepción de riesgo y un cambio de comportamiento para tener relaciones sexuales seguras o de menor riesgo ante las Infecciones de Transmisión Sexual y el Virus de Inmunodeficiencia Humana-SIDA (ITS/VIH-SIDA que al final incidan en la disminución de la transmisión. La metodología incluyó tres momentos claves: la construcción de una línea de base, la implementación de talleres educativos y de información y una evaluación final. Logró captar un total de 380 individuos a nivel nacional. De los resultados mas significativos se pueden mencionar los alcanzados por los participantes que NO pertenecían al sector salud, en los cuales hubo un aumento de conocimientos básicos -transmisión y prevención del VIH- y adquisición de habilidades de un 40% hasta un 60% más de lo encontrado en la línea basal, situación que no resultó ser la misma en los profesionales de salud, en quienes la tendencia fue similar en la línea basal y en la evaluación final. Se concluye que los esfuerzos realizados desde el año 2001 en que dan inicio las intervenciones en poblaciones móviles y que tienen como fin frenar el avance del SIDA en El Salvador no han sido suficientes hasta el momento pues sus estrategias carecen de participación activa de todos los sectores que atienden a dichas poblaciones vulnerables y expuestas a riesgo.

An important problem is that the data of a game world is often scattered across different

    Full Text Available En Medellín, Colombia, el homicidio es la primera causa de morbimortalidad desde hace 20 años y sus tasas de mortalidad superan las de grandes capitales de América Latina. Se describen los actores, las circunstancias y los móviles de los homicidios en Medellín entre 1990 y 2002. De los 55.365 homicidios del período se estudiaron aleatoriamente 1.394, el 93,6% (IC95%: 92,2%-94,8% eran hombres, el 77,0% (IC95%: 75,0%-79,5% menores de 35 años, una cuarta parte estaban ebrios y en 9 de cada 10 fueron muertos con armas de fuego. Los principales móviles del homicidio fueron los ajustes de cuentas y los atracos. El 37,0% (IC95%: 34,0%-41,0% de los muertos provenían de los estratos más bajos de la ciudad y el riesgo de homicidio fue mayor a medida que el estrato socioeconómico era menor. Las características de los asesinatos en Medellín han permanecido invariables desde la década de los ochenta, cuando se inició el período de violencia más alto en la historia de la ciudad. Los grupos más afectados son los hombres jóvenes que viven y mueren en los barrios de estratos socioeconómicos más bajos, en hechos individuales que no dejan heridos.In Medellín, Colombia, homicide has been the first cause of morbidity and mortality for 20 years.

    Full Text Available Somos territoriantes, radicantes, transumers, viajeros en la ciudad global. Con estas figuras damos forma y signiificado al espacio urbano contemporáneo. Dicho espacio y las prácticas que le dan lugar se relacionan con los constantes movimientos, flujos e interconexiones de personas, objetos, datos, ideas y mercancías, vinculándose directamente con el paradigma de la movilidad y con la lógica radicante. En este contexto es necesario el uso de la metodología móvil, ya que es la que mejor se adapta al movimiento de las ciudades contemporáneas y de sus habitantes. Este artículo trata de esta cuestión. Se define la metodología móvil, y se muestra, mediante dos técnicas móviles concretas: la observación participante y la deriva, cómo esta metodología es especialmente útil para estudiar el contexto urbano actual y las prácticas que en él se dan, ya que comparte la lógica constitutiva de los fenómenos estudiados.We are territoriants, radicants, transumers, travelers in the global city. With these figures we give shape and meaning to the contemporary urban space. Such space and the practices that give rise to it are related to the constant movements, flows and interconnections of people, things, data, ideas and goods presently under way, thus befing directly linked to the paradigm of mobility and the radicant logic. In this context, it is necessary to use mobile methodology, the best suited to the contemporary cities and their inhabitants. This paper deals with this issue. Mobile methodology is defined and its practices are shown through two specific mobile techniques: participant observation and drift. The paper also highlights how this methodology is especially usefulfor studying the current urban context and the practices that take place there, as it shares the constitutive logic of the phenomena studied.

  11. IS THE WORLD FLAT?

    Directory of Open Access Journals (Sweden)

    Cristian Încalţărău

    2010-06-01

    Full Text Available Globalization became more and more prominent during the last decades. There is no way to argue that globalization led to more interconnected economies, facilitating the communication and the collaboration around the world. But where is this going? Doesglobalization mean uniformity or diversity? As the world begins to resemble more, the people are trying to distinguish between them more, which can exacerbate nationalistic feeling. Friedman argues that globalization made the world smaller and flatter, allowing all countries to take chance of the available opportunities equally. But is this really true? Although politic and cultural factors can stand in front of a really flat world, what is the key for Chinese and Indian success and which are theirs perspectives?

    Directory of Open Access Journals (Sweden)

    Daniel Reynolds

    2010-07-01

    Full Text Available Sometimes a player will stray from the path described by a game, moving into new spaces, developing new possible modes of interaction, and often discovering the rougher edges of the game world, where physics models break down, textures become incongruous, and the pieces don’t quite fit together. Gameplay that seeks out these spaces and these phenomena, that searches for such clues to the underlying construction of the virtual environment, is a kind of virtual-world naturalism, at once a return to an investigative urge that has been subsumed to the exhaustive mapping and description of the real world and a form of resistance to the very idea of pre-defined paths of action, of externally imposed limits, in virtual worlds as well as in our own.

  18. When Virtual Worlds Expand

    Science.gov (United States)

    Bainbridge, William Sims

    The future of a virtual world depends on whether it can grow in subjective size, cultural content, and numbers of human participants. In one form of growth, exemplified by Second Life, the scope of a world increases gradually as new sponsors pay for new territory and inhabitants create content. A very different form of growth is sudden expansion, as when World of Warcraft (WoW) added entire new continents in its Burning Crusade and Lich King expansions (Lummis and Kern 2006, 2008; Corneliussen and Rettberg 2008; Sims et al. 2008). Well-established gamelike worlds have often undergone many expansions. Both the pioneer science fiction game Anarchy Online, which was launched in 2001, and Star Wars Galaxies dating from 2003, have had three, and EVE Online also from 2003 has had nine, although smaller ones. This chapter reports research on WoW's 2008 Lich King expansion, using both quantitative and qualitative methods, in order to develop theoretical ideas of the implications of expansion for virtual worlds.

  20. Surfing the quantum world

    CERN Document Server

    Levin, Frank S

    2017-01-01

    The ideas and phenomena of the quantum world are strikingly unlike those encountered in our visual world. Surfing the Quantum World shows why and how this is so. It does this via a historical review and a gentle introduction to the fundamental principles of quantum theory, whose core concepts and symbolic representations are used to explain not only "ordinary" microscopic phenomena like the properties of the hydrogen atom and the structure of the Periodic Table of the Elements, but also a variety of mind-bending phenomena. Readers will learn that particles such as electrons and photons can behave like waves, allowing them to be in two places simultaneously, why white dwarf and neutron stars are gigantic quantum objects, how the maximum height of mountains has a quantum basis, and why quantum objects can tunnel through seemingly impenetrable barriers. Included among the various interpretational issues addressed is whether Schrodinger's cat is ever both dead and alive.

    The PhD dissertation compares the literary theory and novels of modern Japanese writer Natsume Sōseki. It reads Sōseki’s Theory of Literature (2009, Bungakuron, 1907) as an inherently comparative and interdisciplinary approach to theorizing feelings in world literature. More broadly......, the dissertation investigates the critical negotiation of the novel as a travelling genre in Japan in the beginning of the 20th century, and, more specifically, Sōseki’s work in relation to world literature and affect theory. Sōseki’s work is highly influential in Japan and East Asia, and his novels widely...... circulated beyond Japan. Using Sōseki’s theory as an example, and by comparing it to other theories, the dissertation argues that comparative literature needs to include not only more non-Western literature but also more non-Western literary theories in the ongoing debate of world literature.

    2016-10-01

    The scale of the decarbonisation challenge to meet the Paris Agreement is underplayed in the public arena. It will require precipitous emissions reductions within 40 years and a new carbon sink on the scale of the ocean sink. Even then, the world is extremely likely to overshoot. A catastrophic failure of policy, for example, waiting another decade for transformative policy and full commitments to fossil-free economies, will have irreversible and deleterious repercussions for humanity's remaining time on Earth. Only a global zero carbon roadmap will put the world on a course to phase-out greenhouse gas emissions and create the essential carbon sinks for Earth-system stability, without which, world prosperity is not possible.

  4. Suicide in the World

    Directory of Open Access Journals (Sweden)

    Peeter Värnik

    2012-03-01

    Full Text Available Introduction: Over the past 20 years the WHO has considerably improved world mortality data. There are still shortcomings but more countries now report data and world-wide estimates are regularly made. Methods: Data about mortality have been retrieved from the WHO world database. Worldwide injury mortality estimates for 2008 as well as trends of the suicide rate from 1950 to 2009 were analysed. Results: Suicides in the world amount to 782 thousand in 2008 according to the WHO estimate, which is 1.4% of total mortality and 15% of injury mortality. The suicide rate for the world as a whole is estimated at 11.6 per 100,000 inhabitants. The male–female rate ratio of suicide is estimated to be highest in the European Region (4.0 and the lowest in the Eastern Mediterranean region (1.1. Among males the highest suicide rate in the 15–29 age group is in the SE Asian region, in the 45–59 age group in European males and for ages above 60 in the Western Pacific region. Females from SE Asia have a remarkably high suicide rate among 15–29-year-olds and from age 45 in the Western Pacific region. The leading country is currently Lithuania, with a suicide rate of 34.1 per 100,000 inhabitants. Also among males the suicide rate is the highest in Lithuania at 61.2. Among females South Korea with 22.1 is at the top of world suicide rates. Conclusions: During the past six decades, according to the WHO Japan, Hungary, and Lithuania have topped the list of world countries by suicide rate, but if the current trends continue South Korea will overtake all others in a few years. The heart of the problem of suicide mortality has shifted from Western Europe to Eastern Europe and now seems to be shifting to Asia. China and India are the biggest contributors to the absolute number of suicides in the world.

Por un lado, en el pictograma fotográfico, el movimiento no sólo aparece como inscripción de un recorrido físico, recogido a través de una serie de imágenes fotosecuenciadas, o por la acción de capturar e ir tras el objetivo, sino también como un trayecto ideológico organizado a través del orden semiótico de la propia imagen fotográfica y del encuadre como estructurador de la mirada. Por otro lado, en el pictograma dibujado, el movimiento es iniciado por el propio acto de marcar y manchar el papel. El dibujo es interpretado como una acción que establece relaciones escénicas y temporales tanto con el espacio real y físico como con la psique. Las obras que han motivado este análisis tituladas La Imagen Negada, Affidamento y Correspondencias persiguen poner en pie una gramática dinámica de la representación. With this article I propose an analytical and comparative approach to movement based on a series of works organised as visual sequences which argue for the syntax of representation using the photographic image, drawing and words. On the one hand, in the sequences of photos, movement does not only appear as an inscription of a physical route, recorded by a fluency of photography images or by the action of capturing and pursuing the objective, but also as an ideological trajectory organised through the semiotic order of the photographic image itself and of the framing as the element that structures the gaze. And on the other hand, in the drawn pictogram, movement is initiated by the very act of marking and staining the paper. Drawing  is interpreted as an action that establishes scenic and temporary relations both with the real, physical space and with the psyche. The works that motivated this analysis, entitled, Affidamento, Posiciones, La imagen negada and Correspondencias, aim to establish a dynamic grammar of representation.

    Full Text Available More than million foods have been made by people from all over the world in the latest years. People now try to create new cooks and make some creativity on it. Then, cooking which the field is culinary has become an art because it needs an artistic value to decorate the food, a good taste and proper technique in processing delicious food in order to make it a masterpiece. French culinary is as famous as the Eiffel tower in the heart of the country, Paris. Most of fine dining international restaurants apply the French menu and cooking. This article presents an overview about the French element in culinary world; starts from its history, kitchen organization, French menu spelling, and French cooking vocabulary. The discussion proceeds library research to compile the data. Later, the art of culinary is interesting to be learned because it contains the classical history of world civilization, in this case French civilization. The issue of cooking trend “nouvelle cuisine” was a masterpiece of one of the greatest chef in his time, Escoffier. French culinary is widely well-known in all over the world because of innovation, creativity, and proud. Those are spirits that we must learn.

    Energy Technology Data Exchange (ETDEWEB)

    Meadows, D.L. (New Hampshire Univ. (USA). Inst. for Policy and Social Science Research)

    1991-10-01

    The Author presents several arguments explaining and backing the mechanics of a world strategy of zero growth. First, attention is brought to Aurelio Peccei's concerns regarding the short-sightedness of the energy and economic policies of industrialized nations. In his book (entitled 'Verso l'Abisso'), written almost 25 years ago, he correctly predicted the severity and timing of current global environmental problems such as the greenhouse effect and acid rain. Urgent and concerted action by world governments is recommended to contain and and remedy damage being caused by a diverse mix of integrated factors - over-population, uncontrolled food production, pollution, over-production by industry, and the improper use of energy and other natural resources. The Author sets guidelines for the creation of a world of steady-state growth in which an equilibrium is reached between overall standards of living and population dynamics. To meet this goal of global man/environment peaceful coexistence, he strongly urges the creation and instillation of a new set of values through the placing of emphasis on the research and development of cultural, psychological, institutional and moral philosophies which, in the last century, have been almost entirely supplanted world-wide by growing materialistic ideals and the pursuit of technological perfection.

    The pious Élisabeth d'Orléans, Mme de Guise, had a vivid correspondence with Armand-Jean de Rancé, abbot of the Cistercian abbey of La Trappe in Normandy. Rancé was considered a champion of unconditional isolation from the world by his contemporaries, but in fact he recommended quite diverse forms...... in remarkable detail how the Duchess should balance her obligations to God and human beings by being a model of withdrawal. To this end she must constantly, in action and demeanour, display to the world her withdrawal from the world. Rancé's spiritual advice to Mme de Guise throws new light on the devotional...... horizon of Gaston d'Orléans's daughter and the pastoral practice of the abbot of La Trappe. Above all, it shows the intricacies and modulations of the withdrawal from the world prescribed to late seventeenth-century aristocratic dévots and, especially, dévotes....

    (Abstract only) New York City in the late 20th century rose to be a planetary capital for the sciences, not just astronomy. This growth was mainly in the academic sector but a parallel growth occurred in the public and home field. With the millennium crossing, scientists in New York agitated for a celebration of the City as a place for a thriving science culture. In 2008 they began World Science Festival. 2011 is the fourth running, on June 1-5, following the AAVSO/AAS meetings. World Science Festival was founded by Dr. Brian Greene, Columbia University, and is operated through the World Science Foundation. The Festival is "saturation science" all over Manhattan in a series of lectures, shows, exhibits, performances. It is staged in "science" venues like colleges and musea, but also in off-science spaces like theaters and galleries. It is a blend from hard science, with lectures like those by us astronomers, to science-themed works of art, dance, music. Events are fitted for the public, either for free or a modest fee. While almost all events are on Manhattan, effort has been made to geographically disperse them, even to the outer boroughs. The grand finale of World Science Festival is a street fair in Washington Square. Science centers in booths, tents, and pavilions highlight their work. In past years this fair drew 100,000 to 150,000 visitors. The entire Festival attracts about a quarter-million attendees. NYSkies is a proud participant at the Washington Square fair. It interprets the "Earth to the Universe" display, debuting during IYA-2009. Attendance at "Earth..." on just the day of the fair plausibly is half of all visitors in America. The presentation shows the scale and scope of World Science Festival, its relation to the City, and how our astronomers work with it.

    Real-world evidence is among the most frequently discussed issues at professional medical conferences and meetings. It refers to data and information derived from sources such as electronic health records, disease or product registries, and observational research. Looking for an accelerated approval of new pharmaceutical products and devices, real-world evidence is considered a useful tool to confirm data collected for regulatory purposes. Anyway, randomised controlled trials still remain the gold standard of clinical research, in order to minimize bias and to evaluate the effectiveness of a clinical intervention. A pragmatic approach and quasi-randomised trials to shorten length and costs of the studies can be considered. The problem lies with the quality of data rather than with the context in which evidence is gathered.

    Full Text Available This article is mainly based on the most recent statistical data of the World Trade Organization and some aspects related to the evolution of world merchandise trade, in terms of volume and value, in 2015. The volume of world merchandise trade continued to grow slowly in 2015 while the dollar value of it declined sharply as exports fell 14 per cent to US$ 16 trillion, down from US$ 19 trillion in the previous year. It presents also the contribution of the volume change and of the change in unit values (which account for fluctuations in prices and exchange rates to the value trade growth (in current dollar terms. The discrepancy between trade growth in 2015 in terms of volume and value was mostly attributable to swings in commodity prices and exchange rates The course of economic globalization is also shortly looked on based on some data and considerations of Credit Suisse analysts. Three different scenarios were taken into account in this respect. First one in which globalization continues in the form we know it over the past thirty years, second one in which a multipolar world is a better representation of the state of affairs and third, a scenario in which globalization ends due to the rise of anti-globalization political movements. The second scenario seems to provide a better reflection of reality today, despite the fact that a certain slowdown is observable when taking into account the diminishing growth rate of physical trade, the slower penetration of foreign assets of the developed market companies and signs of reshoring of some business back home. Globalization remains intact in terms of consumption and marketing patterns, while companies seem more reluctant to invest abroad.

    The United Nations Conference on Environment and Development (UNCED) was held in Rio de Janeiro in June 1992 and dealt with world trade, environmental education, environmental emergencies, the transfer of technology and financial resources, and the restructuring of international systems for tackling environmental problems. Other issues on the agenda were the protection of the atmosphere, the ozone shield, deforestation, the conservation of biological diversity, sustainable urban and rural development, and the safeguarding of human health and quality of life. The preparation for the conference took place through a series of meetings, which also featured the problems of rural areas in the Americas. Some environmental organizations based in Washington, D.C. had become impassive over the years and promoted bipartisan and apolitical issues in order to obtain funds. Nonetheless, some groups criticized the projects of the World Bank. In 1990 the World Bank established the World Environmental Program for developing countries, which envisioned the execution of 15 projects and 11 technical assistance proposals. Nongovernmental organizations (NGOs) were also active in this effort. The Interamerican Development Bank also launched a forest policy for preserving forest resources. This was the consequence of the 1982 scheme that aimed at protecting forest populations and promoting sustainable forest industries. At another conference of development specialists the discrimination against women was cited as a major factor in the deleterious use of natural resources. A new development concept was urged that would incorporate the rights and participation of women as a central strategy in solving the global environmental crisis. The global population is growing at a rate of 95 million people per year, which underlines the need for better representation of women, poor people, and rural areas in state agencies and multilateral and environmental organizations for promoting sustainable

    The observable universe could be a 1+3-surface (the "brane") embedded in a 1+3+d-dimensional spacetime (the "bulk"), with Standard Model particles and fields trapped on the brane while gravity is free to access the bulk. At least one of the d extra spatial dimensions could be very large relative to the Planck scale, which lowers the fundamental gravity scale, possibly even down to the electroweak (∼ TeV) level. This revolutionary picture arises in the framework of recent developments in M theory. The 1+10-dimensional M theory encompasses the known 1+9-dimensional superstring theories, and is widely considered to be a promising potential route to quantum gravity. At low energies, gravity is localized at the brane and general relativity is recovered, but at high energies gravity "leaks" into the bulk, behaving in a truly higher-dimensional way. This introduces significant changes to gravitational dynamics and perturbations, with interesting and potentially testable implications for high-energy astrophysics, black holes, and cosmology. Brane-world models offer a phenomenological way to test some of the novel predictions and corrections to general relativity that are implied by M theory. This review analyzes the geometry, dynamics and perturbations of simple brane-world models for cosmology and astrophysics, mainly focusing on warped 5-dimensional brane-worlds based on the Randall-Sundrum models. We also cover the simplest brane-world models in which 4-dimensional gravity on the brane is modified at low energies - the 5-dimensional Dvali-Gabadadze-Porrati models. Then we discuss co-dimension two branes in 6-dimensional models.

    Sarute, Nicolás; Ross, Susan R

    2017-09-29

    Hemorrhagic fevers caused by viruses were identified in the late 1950s in South America. These viruses have existed in their hosts, the New World rodents, for millions of years. Their emergence as infectious agents in humans coincided with changes in the environment and farming practices that caused explosions in their host rodent populations. Zoonosis into humans likely occurs because the pathogenic New World arenaviruses use human transferrin receptor 1 to enter cells. The mortality rate after infection with these viruses is high, but the mechanism by which disease is induced is still not clear. Possibilities include direct effects of cellular infection or the induction of high levels of cytokines by infected sentinel cells of the immune system, leading to endothelia and thrombocyte dysfunction and neurological disease. Here we provide a review of the ecology and molecular and cellular biology of New World arenaviruses, as well as a discussion of the current animal models of infection. The development of animal models, coupled with an improved understanding of the infection pathway and host response, should lead to the discovery of new drugs for treating infections.

In the WEO-2008 Reference Scenario, which assumes no new government policies, world primary energy demand grows by 1.6% per year on average between 2006 and 2030 - an increase of 45%. This is slower than projected last year, mainly due to the impact of the economic slowdown, prospects for higher energy prices and some new policy initiatives. Demand for oil rises from 85 million barrels per day now to 106 mb/d in 2030 - 10 mb/d less than projected last year. Demand for coal rises more than any other fuel in absolute terms, accounting for over a third of the increase in energy use. Modern renewables grow most rapidly, overtaking gas to become the second-largest source of electricity soon after 2010. China and India account for over half of incremental energy demand to 2030 while the Middle East emerges as a major new demand centre. The share of the world's energy consumed in cities grows from two-thirds to almost three-quarters in 2030. Almost all of the increase in fossil-energy production occurs in non-OECD countries. These trends call for energy-supply investment of $26.3 trillion to 2030, or over 1 trillion US dollars/year. Yet the credit squeeze could delay spending, potentially setting up a supply-crunch that could choke economic recovery. In addition to providing a comprehensive update of long-term energy projections to 2030, WEO-2008 takes a detailed look at the prospects for oil and gas production. Oil will remain the world's main source of energy for many years to come, even under the most optimistic of assumptions about the development of alternative technology. But the sources of oil, the cost of producing it and the prices that consumers will have to pay for it are extremely uncertain. It is far from certain that companies

Global trade and improved logistics open up to the markets. To facilitate international trade in bioenergy commodities, new trading places and indexes are needed, as well as generally accepted standards. Supply and demand must meet to guarantee stable prices. In this session you learn all about current market development, including drivers like incentives and policies. C) Energy Systems: Modern bioenergy is a young industry. Therefore, technical development is rapid, with many new innovations. This session focuses on technical development in the whole bioenergy chain, from harvesting of forest residues to combustion technologies and co-firing. Optimal use of biomass through district heating or cooling - small scale and large scale - and CHP technology for electricity production. D) Transportation: Sustainable transports are one of the key challenges of tomorrow. Can we transport biomass as well as other products sustainably and at what costs? Which are the future fuels for transports and when will biofuels be viewed as profitable? Biofuels for transport are under rapid development with new methods, producers and feedstock entering the markets. The future biofuels will be produced in biorefineries, to increase profitability and optimize feed

    The control of human onchocerciasis (river blindness) is one of the most successful global partnerships ever supported by the World Bank. Mectizan mass treatments have greatly contributed to this success and have shaped the strategies of the programmes in which the World Bank has been involved - the Onchocerciasis Control Programme (OCP), which covered onchocerciasis control in West Africa until 2002, and the African Programme for Onchocerciasis Control (APOC), which is currently working in 30 countries, to protect millions of people from onchocerciasis. Through the strategy of community-directed treatment with ivermectin (CDTI), onchocerciasis control in Africa was transformed from a technologically-driven and vertical health initiative to a community-directed process of treatment and empowerment. Together, CDTI and the donation of Mectizan also reduced costs, producing one of the most effective and affordable disease-control schemes ever seen, and the CDTI strategy is now being applied to other disease-control initiatives. The onchocerciasis programmes have also been exemplary in shaping partnerships with communities, countries, the World Health Organization, governments, non-governmental development organizations, and the private sector. The Bank's involvement in onchocerciasis control has helped mobilize funds, giving confidence to other donors. More than U. S.$800 million was raised for both the OCP and APOC (excluding the initial costs of Mectizan). With these funds and the commitment of the partners involved, high coverages have been achieved in the Mectizan distributions. The Bank is confident that, during the years to come, the partners will continue their success, and that the APOC will achieve its goals by the target date for its closure, in 2015.

    Full Text Available The observable universe could be a 1+3-surface (the "brane" embedded in a 1+3+$d$-dimensional spacetime (the "bulk", with Standard Model particles and fields trapped on the brane while gravity is free to access the bulk. At least one of the $d$ extra spatial dimensions could be very large relative to the Planck scale, which lowers the fundamental gravity scale, possibly even down to the electroweak ($sim$TeV level. This revolutionary picture arises in the framework of recent developments in M theory. The 1+10-dimensional M theory encompasses the known 1+9-dimensional superstring theories, and is widely considered to be a promising potential route to quantum gravity. General relativity cannot describe gravity at high enough energies and must be replaced by a quantum gravity theory, picking up significant corrections as the fundamental energy scale is approached. At low energies, gravity is localized at the brane and general relativity is recovered, but at high energies gravity "leaks" into the bulk, behaving in a truly higher-dimensional way. This introduces significant changes to gravitational dynamics and perturbations, with interesting and potentially testable implications for high-energy astrophysics, black holes and cosmology. Brane-world models offer a phenomenological way to test some of the novel predictions and corrections to general relativity that are implied by M theory. This review discusses the geometry, dynamics and perturbations of simple brane-world models for cosmology and astrophysics, mainly focusing on warped 5-dimensional brane-worlds based on the Randall-Sundrum models.

    2016-01-01

    We analyze the physics of the "world's simplest electric train." The "train" consists of a AA battery with a strong magnet on each end that moves through a helical coil of copper wire. The motion of the train results from the interaction between the magnetic field created by the current in the wire and the magnetic field of the magnets. We calculate the force of this interaction and the terminal velocity of the train due to eddy currents and friction. Our calculations provide a good illustration of Faraday's and Lenz's laws, as well as of the concepts of the Lorentz force and eddy currents.

    We examine in detail the circumstances under which reciprocity, as defined in Bagwell and Staiger (1999), leads to fixed world prices. We show that a change of tariffs satisfying reciprocity does not necessarily imply constant world prices in a world of many goods and countries. While...... it is possible to find tariff reforms that are consistent with both reciprocity and constant world prices, these reforms do not follow from the reciprocity condition, but rather from the requirement of unchanged world prices. We propose an alternative reciprocity rule that is guaranteed to raise the welfare...... of all countries, independently of whether world prices change and independently of the relative numbers of goods and countries....

    Although tidally locked habitable planets orbiting nearby M-dwarf stars are among the best astronomical targets to search for extrasolar life, they may also be deficient in volatiles and water. Climate models for this class of planets show atmospheric transport of water from the dayside to the nightside, where it is precipitated as snow and trapped as ice. Since ice only slowly flows back to the dayside upon accumulation, the resulting hydrological cycle can trap a large amount of water in the form of nightside ice. Using ice sheet dynamical and thermodynamical constraints, I illustrate how planets with less than about a quarter the Earth's oceans could trap most of their surface water on the nightside. This would leave their dayside, where habitable conditions are met, potentially dry. The amount and distribution of residual liquid water on the dayside depend on a variety of geophysical factors, including the efficiency of rock weathering at regulating atmospheric CO{sub 2} as dayside ocean basins dry up. Water-trapped worlds with dry daysides may offer similar advantages as land planets for habitability, by contrast with worlds where more abundant water freely flows around the globe.

    Full Text Available The workshop “Sensing a Changing World” was held in Wageningen, The Netherlands, from November 19–21, 2008. The main goal of the workshop was to explore and discuss recent developments in sensors and (wireless sensor networks for monitoring environmental processes and human spatial behavior in a changing world. The challenge is then to develop concepts and applications that can provide timely and on-demand knowledge to end-users in different domains over a range of different spatial and temporal scales. During this workshop over 50 participants, representing 15 countries, presented and discussed their recent research. The workshop provided a broad overview of state-of-the-art research in a broad range of application fields: oceanography, air quality, biodiversity and vegetation, health, tourism, water management, and agriculture. In addition the workshop identified the future research challenges. One of the outcomes of the workshop was a special issue in the journal Sensors with contributions presented at the workshop. This editorial of the special issue aims to provide an overview of the discussions held during the workshop. It highlights the ideas of the authors and participants of the workshop about directions of future research for further development of sensor-webs for “sensing” spatial phenomena. The “big” question was are we already able to sense a changing world? And if the answer is positive, then what are we going to sense and for what?

  5. Belief in a Just World

    Full Text Available Belief in a just world hypothesis is defined as the belief that the world is a just place where people generally get what they deserve. It states that individuals have a need to believe that they live in a just world; they believe in a world where people get what they deserve and where people deserve what they get. Individuals believe that who work hard or who perform good acts obtain rewards for their actions, while the sinners and the laggards receive punishments instead. Similarly, individuals want to believe that positive outcomes, whether money, success, or happiness, are obtained only by good people and, conversely, that negative outcomes only happen to bad persons. Justice beliefs have been hypothesized as adaptive for dealing with day-to-day stres. Just world beliefs protect individuals from the daily negative psychological consequences of living in what is realistically an unjust world. In addition, just world beliefs are thought to enhance feelings of security to the extent that if the individual satisfies the conditions for being "good," he or she is protected from injustice. The belief in a just world, like other positive illusions, should contribute to the maintenance of one's mental health. Belief in a just world's is discussed in two ways: personal belief in a just world's answers the question “how much justly is the world to me?”, whereas the belief in a just world's in general answers the question “how much justly is the world?”

    This report forms part of a project entitled 'World Biofuels Study'. The objective is to study world biofuel markets and to examine the possible contribution that biofuel imports could make to help meet the Renewable Fuel Standard (RFS) of the Energy Independence and Security Act of 2007 (EISA). The study was sponsored by the Biomass Program of the Assistant Secretary for Energy Efficiency and Renewable Energy (EERE), U.S. Department of Energy. It is a collaborative effort among the Office of Policy and International Affairs (PI), Department of Energy and Oak Ridge National Laboratory (ORNL), National Renewable Energy Laboratory (NREL) and Brookhaven National Laboratory (BNL). The project consisted of three main components: (1) Assessment of the resource potential for biofuel feedstocks such as sugarcane, grains, soybean, palm oil and lignocellulosic crops and development of supply curves (ORNL). (2) Assessment of the cost and performance of biofuel production technologies (NREL). (3) Scenario-based analysis of world biofuel markets using the ETP global energy model with data developed in the first parts of the study (BNL). This report covers the modeling and analysis part of the project conducted by BNL in cooperation with PI. The Energy Technology Perspectives (ETP) energy system model was used as the analytical tool for this study. ETP is a 15 region global model designed using the MARKAL framework. MARKAL-based models are partial equilibrium models that incorporate a description of the physical energy system and provide a bottom-up approach to study the entire energy system. ETP was updated for this study with biomass resource data and biofuel production technology cost and performance data developed by ORNL and NREL under Tasks 1 and 2 of this project. Many countries around the world are embarking on ambitious biofuel policies through renewable fuel standards and economic incentives. As a result, the global biofuel demand is expected to grow very

    This article offers health leaders in Canada an opportunity to build a more worldly understanding of healthcare challenges. The focus is on post-conflict countries and island/small countries. Small and island countries often depend on other countries for their workforce and for specialist healthcare services. Conflict usually undermines if it doesn't destroy a country's healthcare system. Small and island countries offer opportunities for the majority of Canadian provinces and territories to develop new approaches from novel comparator countries, with which they may have more in common. Post-conflict countries offer an opportunity to consider the applicability of the determinants of policy and institutional failure to Aboriginal healthcare in Canada.

    The world appears to be emerging from the worst economic crisis in decades. Many countries have made pledges under the Copenhagen Accord to reduce greenhouse-gas emissions. Commitments have also been made by the G-20 and APEC to phase out inefficient fossil-fuel subsidies. Are we, at last, on the path to a secure, reliable and environmentally sustainable energy system? Updated projections of energy demand, production, trade and investment, fuel by fuel and region by region to 2035 are provided in the 2010 edition of the World Energy Outlook (WEO). It includes, for the first time, a new scenario that anticipates future actions by governments to meet the commitments they have made to tackle climate change and growing energy insecurity. WEO-2010 shows: what more must be done and spent to achieve the goal of the Copenhagen Accord to limit the global temperature increase to 2 deg. C and how these actions would impact on oil markets; how emerging economies -- led by China and India -- will increasingly shape the global energy landscape; what role renewables can play in a clean and secure energy future; what removing fossil-fuel subsidies would mean for energy markets, climate change and state budgets; the trends in Caspian energy markets and the implications for global energy supply; the prospects for unconventional oil; and how to give the entire global population access to modern energy services. With extensive data, projections and analysis, this publication provides invaluable insights into how the energy system could evolve over the next quarter of a century. The book is essential reading for anyone with a stake in the energy sector.

    Full Text Available World-systems analysis is not a theory, but an approach to social analysis and social change developed, among others by the Immanuel Wallerstein. Professor Wallerstein writes in three domains of world-systems analysis: the historical development of the modern world-system; the contemporary crisis of the capitalist world-economy; the structures of knowledge. The American anlyst rejects the notion of a "Third World", claiming there is only one world connected by a complex network of economic exchange relationship. Our world system is characterized by mechanisms which bring about a redistribution of resources from the periphery to the core. His analytical approach has made a significant impact and established an institutional base devoted to the general approach.

  3. Many worlds in perspective

    Science.gov (United States)

    Päs, Heinrich

    2017-08-01

    A minimal approach to the measurement problem and the quantum-to-classical transition assumes a universally valid quantum formalism, i.e. unitary time evolution governed by a Schrödinger-type equation. As had been pointed out long ago, in this view the measurement process can be described by decoherence which results in a ”Many-Worlds” or ”Many-Minds” scenario according to Everett and Zeh. A silent assumption for decoherence to proceed is however, that there exists incomplete information about the environment our object system gets entangled with in the measurement process. This paper addresses the question where this information is traced out and - by adopting recent approaches to model consciousness in neuroscience - argues that a rigorous interpretation results in a perspectival notion of the quantum-to-classical transition. The information that is or is not available in the consciousness of the observer is crucial for the definition of the environment (i.e. the unknown degrees of freedom in the remainder of the Universe). As such the Many-Worlds-Interpretation, while being difficult or impossible to probe in physics, may become testable in psychology.

  4. Uncertain Science… Uncertain World

    Science.gov (United States)

    Lempert, Robert

    Why doesn't society act in the face of overwhelming evidence that human influences are changing the Earth's climate? Henry Pollack devotes his book, Uncertain Science… Uncertain World, to addressing one important reason. Much about climate science is highly uncertain, he argues; and as a general rule, most well-educated citizens don't understand the nature of scientific uncertainty. Thus, they have difficulty understanding competing claims made by advocates in the policy debate and in internalizing the extent of the problem.A distinguished professor of geophysics at the University of Michigan, as well as a participant in many public debates involving science, Pollack aims to help lay readers understand the role of uncertainty in science. “In making comparisons and analogies with uncertainties that exist in science and everyday life,” he writes, “my goal is to help readers to understand and accommodate scientific uncertainties in much the same way that they deal with other uncertainties in life.”

  5. A WORLD BEYOND HUMAN

    Directory of Open Access Journals (Sweden)

    David Abram

    2013-12-01

    Full Text Available From an initial project to investigate the relationship between magic and traditional medicine as practiced by shamans in Southern rural Asia, the focus of attention gradually shifted to an awareness of the negotiation traditional medicine people or shamans exert between the human community and the larger community of beings. This attentiveness to a more-than-human world does not occur at a supernatural domain above nature or inside her personal self but is the result of the shaman’s special ability to project her consciousness horizontally to other forms of sensibility with which human existence is interwoven. The ecological function of the shaman is to maintain a constant balance between what is taken and what is given from the human community to the larger community. The spirits of indigenous cultures are not defined in opposition to materiality but are essentially those modes of intelligence or awareness that do not possess a human form. By exploring different landscapes, and the sensibility living in them, a new sensitivity is awoken that allows for communication with those intelligences. However, the drowning of these other voices in Western culture, which reduces otherness to an object, creates an uneasiness that is hardly perceived except as an inability to interact with anything more-than-human and its dire consequences in the form of “civilization’s” destructive behavior.

  6. World Cup Final

    Science.gov (United States)

    2006-01-01

    On July 9, hundreds of millions of fans worldwide will be glued to their television sets watching the final match of the 2006 FIFA World Cup, played in Berlin's Olympic stadium (Olympiastadion). The stadium was originally built for the 1936 Summer Olympics. The Olympic Stadium seats 76,000,; its roof rises 68 meters over the seats and is made up of transparent panels that allow sunlight to stream in during the day. With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet. ASTER is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping, and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance. The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The Terra mission is part of NASA's Science Mission Directorate. Size: 12.1 by 15.9 kilometers (7.5 by 9.5 miles) Location: 52.5 degrees North latitude, 13.3 degrees East longitude Orientation: North at top Image Data: ASTER bands 3, 2, and 1 Original Data Resolution: 15 meters (49.2 feet) Dates Acquired: October 15, 2005

    There are more than a billion Muslims in the world today - over a fifth of the world's total population - spread over many more than the 57 member states of the Organisation of the Islamic Conference (OIC) in which Islam is the official religion. These include some of the world's wealthiest nations, such as Saudi Arabia and Kuwait, as well as some of the poorest, like Somalia and Sudan. The economies of some of these countries - such as the Gulf States, Iran, Turkey, Egypt, Morocco, Malaysia and Pakistan - have been growing steadily for a number of years, and yet, in comparison with the West, the Islamic world still appears somewhat disengaged from modern science.

    Nicole is a beautiful 14-month wide-eyed girl who presents for routine health care maintenance in your office. Since her 9 month visit, her weight has fallen from the 25th percentile to significantly less than the 5th percentile. Her height has dropped from the 10th percentile to slightly less than the 5th percentile, while her head circumference has remained at about the 25th percentile. Her language, motor, cognitive, and social development are normal. She is 2 months late for this visit as her family has recently had significant family loss because of the earthquake in Haiti. When you take a feeding history, she seems to eat age-appropriate foods--macaroni, chicken pieces--but her mother notes that she tends to be restless and fidgety while eating and will no longer sit still in her mother's lap while she feeds her. Her stools tend to be frequent, with particles of food seen. Urine is normal. There are no symptoms of respiratory or neurological disease, and her review of systems is otherwise negative. She has been a healthy child and this is the first time they have fallen behind in routine health care maintenance visits. Her medical history is entirely unremarkable. She was born at term, weighing 3.5 kg, without any perinatal complications. The family has lived in the United States for the last 10 years. Mother recalls that there were other children in her family who were deemed small as young children but who caught up later in childhood. Mother describes a history of increased sadness and worry in the last 2 months. They receive phone calls from family in Haiti several times per week and she admits to being upset during and after these calls. When asked how the event has impacted her family, she states, "It has rocked our entire world but Nicole is just a baby who won't eat!" Parents are married, and there is no history of abuse or violence in the household. Her physical examination is essentially normal. Her anterior fontanelle is still open, roughly 2 cm

  13. Managing the world's forests.

    Science.gov (United States)

    Sharma, N; Rowe, R

    1992-06-01

    Forests play a vital role in balancing natural systems: the stabilization of global climate and the management of water and land. 30% of the earth's total land area is forested. 66% of the tropical moist forests are in Latin America and the remainder in Africa and Asia. 75% of tropical dry forests are in Africa. Temperate forests are primarily in developed countries. Deforestation and misuse of forests occurs primarily in developing countries at significant social, economic, and environmental costs. Losses have occurred in fuelwood, fodder, timber, forest products, biological diversity, habitats, genetic materials for food and medicine. The World Bank's evolving role in forestry is briefly described. Agreement has not been reached among people or nations about the most appropriate means to balance conservation and development goals. The challenge is to stabilize existing forests and increase forest planting. The causes of forest degradation must be understood. Direct causes include agricultural encroachment, cattle ranching, fuelwood gathering, commercial logging, and infrastructure development. These direct causes are driven by economic, social, and political forces: market and policy failures, population growth, and poverty. The market failures include: 1) the lack of clearly defined property rights on forest resources for now and the future, 2) the conflict between individual and societal needs, 3) the difficulty in placing a value on nonmarket environmental services and joint products, and 4) the separation between private and social costs. The solution is action at the local, national, and global levels. Countries must establish forest policy. The existing government incentives which promote deforestation must be changed. For example, concession policy and royalty systems must be corrected; explicit and implicit export subsidies on timber and forest products must be stopped. Private incentives must be established to promote planting of trees, practicing

  18. Virtual Worlds for Virtual Organizing

    Science.gov (United States)

    Rhoten, Diana; Lutters, Wayne

    The members and resources of a virtual organization are dispersed across time and space, yet they function as a coherent entity through the use of technologies, networks, and alliances. As virtual organizations proliferate and become increasingly important in society, many may exploit the technical architecture s of virtual worlds, which are the confluence of computer-mediated communication, telepresence, and virtual reality originally created for gaming. A brief socio-technical history describes their early origins and the waves of progress followed by stasis that brought us to the current period of renewed enthusiasm. Examination of contemporary examples demonstrates how three genres of virtual worlds have enabled new arenas for virtual organizing: developer-defined closed worlds, user-modifiable quasi-open worlds, and user-generated open worlds. Among expected future trends are an increase in collaboration born virtually rather than imported from existing organizations, a tension between high-fidelity recreations of the physical world and hyper-stylized imaginations of fantasy worlds, and the growth of specialized worlds optimized for particular sectors, companies, or cultures.

Intuitively, while such agents may fail to rule out subtly impossible worlds that verify complex logical...... falsehoods, they are nevertheless able to rule out blatantly impossible worlds that verify obvious logical falsehoods. To model moderately ideal agents, I argue, the job is to construct a modal space that contains only possible and non-trivially impossible worlds where it is not the case that “anything goes......”. But I prove that it is impossible to develop an impossible-world framework that can do this job and that satisfies certain standard conditions. Effectively, I show that attempts to model moderately ideal agents in a world-involving framework collapse to modeling either logical omniscient agents...

    2006-12-01

    Virtual Labs and Virtual Worlds Coastline Community College has under development several virtual lab simulations and activities that range from biology, to language labs, to virtual discussion environments. Imagine a virtual world that students enter online, by logging onto their computer from home or anywhere they have web access. Upon entering this world they select a personalized identity represented by a digitized character (avatar) that can freely move about, interact with the environment, and communicate with other characters. In these virtual worlds, buildings, gathering places, conference rooms, labs, science rooms, and a variety of other “real world” elements are evident. When characters move about and encounter other people (players) they may freely communicate. They can examine things, manipulate objects, read signs, watch video clips, hear sounds, and jump to other locations. Goals of critical thinking, social interaction, peer collaboration, group support, and enhanced learning can be achieved in surprising new ways with this innovative approach to peer-to-peer communication in a virtual discussion world. In this presentation, short demos will be given of several online learning environments including a virtual biology lab, a marine science module, a Spanish lab, and a virtual discussion world. Coastline College has been a leader in the development of distance learning and media-based education for nearly 30 years and currently offers courses through PDA, Internet, DVD, CD-ROM, TV, and Videoconferencing technologies. Its distance learning program serves over 20,000 students every year. sponsor Jerry Meisner

  3. Wikipedia ranking of world universities

    Science.gov (United States)

    Lages, José; Patt, Antoine; Shepelyansky, Dima L.

    2016-03-01

    We use the directed networks between articles of 24 Wikipedia language editions for producing the wikipedia ranking of world Universities (WRWU) using PageRank, 2DRank and CheiRank algorithms. This approach allows to incorporate various cultural views on world universities using the mathematical statistical analysis independent of cultural preferences. The Wikipedia ranking of top 100 universities provides about 60% overlap with the Shanghai university ranking demonstrating the reliable features of this approach. At the same time WRWU incorporates all knowledge accumulated at 24 Wikipedia editions giving stronger highlights for historically important universities leading to a different estimation of efficiency of world countries in university education. The historical development of university ranking is analyzed during ten centuries of their history.

  4. World-line perturbation theory

    CERN Document Server

    van Holten, Jan-Willem

    2016-01-01

    The motion of a compact body in space and time is commonly described by the world line of a point representing the instantaneous position of the body. In General Relativity such a world-line formalism is not quite straightforward because of the strict impossibility to accommodate point masses and rigid bodies. In many situations of practical interest it can still be made to work using an effective hamiltonian or energy-momentum tensor for a finite number of collective degrees of freedom of the compact object. Even so exact solutions of the equations of motion are often not available. In such cases families of world lines of compact bodies in curved space-times can be constructed by a perturbative procedure based on generalized geodesic deviation equations. Examples for simple test masses and for spinning test bodies are presented.

  5. Virtual Laboratories and Virtual Worlds

    Hut, Piet

    2008-05-01

    Since we cannot put stars in a laboratory, astrophysicists had to wait till the invention of computers before becoming laboratory scientists. For half a century now, we have been conducting experiments in our virtual laboratories. However, we ourselves have remained behind the keyboard, with the screen of the monitor separating us from the world we are simulating. Recently, 3D on-line technology, developed first for games but now deployed in virtual worlds like Second Life, is beginning to make it possible for astrophysicists to enter their virtual labs themselves, in virtual form as avatars. This has several advantages, from new possibilities to explore the results of the simulations to a shared presence in a virtual lab with remote collaborators on different continents. I will report my experiences with the use of Qwaq Forums, a virtual world developed by a new company (see http://www.qwaq.com).

  6. Synchronization of world economic activity

    Science.gov (United States)

    Groth, Andreas; Ghil, Michael

    2017-12-01

    Common dynamical properties of business cycle fluctuations are studied in a sample of more than 100 countries that represent economic regions from all around the world. We apply the methodology of multivariate singular spectrum analysis (M-SSA) to identify oscillatory modes and to detect whether these modes are shared by clusters of phase- and frequency-locked oscillators. An extension of the M-SSA approach is introduced to help analyze structural changes in the cluster configuration of synchronization. With this novel technique, we are able to identify a common mode of business cycle activity across our sample, and thus point to the existence of a world business cycle. Superimposed on this mode, we further identify several major events that have markedly influenced the landscape of world economic activity in the postwar era.

  9. World sheets of spinning particles

    Science.gov (United States)

    Kaparulin, D. S.; Lyakhovich, S. L.

    2017-11-01

    The classical spinning particles are considered such that quantization of classical model leads to an irreducible massive representation of the Poincaré group. The class of gauge equivalent classical particle world lines is shown to form a [(d +1 )/2 ]-dimensional world sheet in d -dimensional Minkowski space, irrespectively to any specifics of the classical model. For massive spinning particles in d =3 , 4, the world sheets are shown to be circular cylinders. The radius of the cylinder is fixed by representation. In higher dimensions, the particle's world sheet turns out to be a toroidal cylinder R ×TD, D =[(d -1 )/2 ]. Proceeding from the fact that the world lines of irreducible classical spinning particles are cylindrical curves, while all the lines are gauge equivalent on the same world sheet, we suggest a method to deduce the classical equations of motion for particles and also to find their gauge symmetries. In d =3 Minkowski space, the spinning particle path is defined by a single fourth-order differential equation having two zero-order gauge symmetries. The equation defines the particle's path in Minkowski space, and it does not involve auxiliary variables. A special case is also considered of cylindric null curves, which are defined by a different system of equations. It is shown that the cylindric null curves also correspond to irreducible massive spinning particles. For the higher-derivative equation of motion of the irreducible massive spinning particle, we deduce the equivalent second-order formulation involving an auxiliary variable. The second-order formulation agrees with a previously known spinning particle model.

    World Nuclear Association recently published the 2017 edition of the World Nuclear Performance Report. The report presents key metrics that illustrate current performance, both of reactors currently operating and those under construction. The article highlights some of the most important findings of the report. The pace of new build will need to accelerate if nuclear energy is going to make a growing contribution to the global electricity generation mix, a requirement of many projections of future scenarios that aim to meet the objective of limiting the rise average temperatures to below two degrees Celsius, while at the same time meeting the growing worldwide demand for electricity.

    The world has recently experienced rapid change to market-driven economies and increasing reliance on petroleum supplies from areas of political instability. The interplay of unprecedented growth of the global population, increasing worldwide energy demand, and political instability in two major petroleum exporting regions (the former Soviet Union and the Middle East) requires that the United States maintains a current, reliable, objective assessment of the world's energy resources. The need is compounded by the environmental implications of rapid increases in coal use in the Far East and international pressure on consumption of fossil fuels.

  20. One world of veterinary medicine.

    Science.gov (United States)

    King, L J

    2009-08-01

    The veterinary profession finds itself in the midst of a new world order. Today veterinarians are part of a world that is exquisitely interconnected culturally, economically, socially, and professionally. As a consequence, societal needs and expectations of the profession are more demanding, critical and far-reaching. Veterinarians must play important roles in five intersecting domains of work: public health, bio-medical research, global food safety and security, ecosystem health and the more traditional role of caring for animals. To be successful in this broad and complex range of services and activities, veterinarians must possess an expanded knowledge base, acquire new skills, and develop a new mindset that will ensure their success and excellence in all these domains. The veterinary profession is becoming more fragmented and specialised, and it needs to be brought back together by a single sphere of knowledge or discipline that can serve as an intellectual foundation. The concept of One World of Veterinary Medicine can do just that. With this mindset veterinarians will become better connected to the world around and gain new public recognition and esteem. To achieve this, a special commitment by academic veterinary medicine is, of course, essential. Veterinary schools must lead an educational transformation that reaffirms the social contract of veterinarians and works to align diverse sectors, build a global community, find a common purpose and expand the 21st Century veterinary portfolio of services, activities, and new possibilities.

  1. World Input-Output Network.

    Directory of Open Access Journals (Sweden)

    Federica Cerina

    Full Text Available Production systems, traditionally analyzed as almost independent national systems, are increasingly connected on a global scale. Only recently becoming available, the World Input-Output Database (WIOD is one of the first efforts to construct the global multi-regional input-output (GMRIO tables. By viewing the world input-output system as an interdependent network where the nodes are the individual industries in different economies and the edges are the monetary goods flows between industries, we analyze respectively the global, regional, and local network properties of the so-called world input-output network (WION and document its evolution over time. At global level, we find that the industries are highly but asymmetrically connected, which implies that micro shocks can lead to macro fluctuations. At regional level, we find that the world production is still operated nationally or at most regionally as the communities detected are either individual economies or geographically well defined regions. Finally, at local level, for each industry we compare the network-based measures with the traditional methods of backward linkages. We find that the network-based measures such as PageRank centrality and community coreness measure can give valuable insights into identifying the key industries.

    Full Text Available Digital imaging is now firmly ensconced in the developed world. Its widespread adoption has enabled instant access to images, remote viewing, remote consultation, and the end of lost or misplaced film. Unfortunately, the current paradigm of Picture Archiving and Communication System (PACS, with advanced technology inseparable from high complexity, high purchase costs, and high maintenance costs, is not suited for the low-income developing world. Like the simple, easy to repair, 1950’s American cars still running on the streets of Havana, the developing world requires a PACS (DW-PACS that can perform basic functions and survive in a limited-resource environment. The purpose of this article is to more fully describe this concept and to present a blueprint for PACS tailored to the needs and resources of the developing world. This framework should assist both users looking for a vendor-supplied or open-source solutions and developers seeking to address the needs of this emerging market.

However, pharmaceuticals are frequently being used irrationally, mainly due to market imperfections in health care, such as information asymmetries, leading to serious health problems and a heavy financial burden on the health system. Lending priorities set by the World Bank could be used to promote public health sector reform, leading to the rational use of affordable and available drugs of good quality in developing countries. This report provides the first analysis of World Bank activity in the pharmaceutical sector worldwide. The analysis of 77 staff appraisal reports, describing the planning phase of World Bank country projects, shows that 16% of the total World Bank health, nutrition and population budget, or approximately US$1.3 billion, has been committed to loans or credits supporting pharmaceutical activities in the programme countries between 1989-95. Roughly US$1.05 billion has been committed to procurement of drugs and medical equipment. Only 5% of the total pharmaceutical sector lending is committed to software components such as drug policy work and rational use of drugs. No more than 45% of the projects were developed in collaboration with pharmaceutical expertise. The World Bank is recommended to improve its pharmaceutical sector involvement by promoting drug policy research and development including national and international dialogue on pharmaceutical issues to ensure rational use of both drugs and loans. In this, the World Bank has an advantage given its experience from working with both the private and

    Can the increasing global energy consumption be met without intensifying global warming? Do the necessary technical solutions exist, and is the switch to a low-carbon energy supply feasible and financially viable? These crucial questions and many others were dealt with at the 2011World Engineer’s Convention (WEC). CERN was invited to participate in the event, highlighting its significant contribution to global engineering with an exhibition space devoted to the LHC on the convention floor and a keynote speech delivered by CERN’s Director-General.   From 4 – 9 September 2011, more than 2000 engineers and researchers, as well as politicians and business representatives from about 100 countries gathered at the 2011World Engineer’s Convention (WEC).

    2007-01-31

    Parasitic diseases are cosmopolitan and may affect all the world population. They kill several million people every year. The migrations and tourism make that even tropical diseases can be frequently met outside their geographical distribution area. Except the arthropod-borne infections, the great majority of these diseases are in relation with the faecal contamination of soil, the general level of hygiene and the food practices. Malaria remains the first world parasitic disease in term of mortality. The strong fall of the amoebic endemicity is due only to the improvement of the methods of molecular diagnosis. The socio-political and climatic upheavals may result in a creeping extension of the geographical limits of many parasites.

  1. Tuvan music and World Music

    2017-06-01

    Full Text Available The essay presents the author’s observations about the ingression of Tuvan music into the World Music – a niche of world musical culture covering ethnical music traditions. The author has witnessed the rise of interest to traditional musical culture of Tuva and Russia as well as globalization of Tuvan music. He is endeavoring to interpret these changes and reveal their affect on traditional music and xöömei. In the late Soviet period, traditional music in Tuva, like in many republics of the Union, has been as if put on hold. During the Perestroika and national revival processes, traditionalism became of high demand. Symposia and festivals started off in Tuva where amateur participants took the same stage with professionals. Special honor was paid to old masters of xöömei. Scholars started engaging in  discussions about the origins and a role of xöömei and its genres. Хöömei attracted a good deal of market interest from outside Russia. In the late 1980s American scientist and producer T. Levin made first field records of xöömei to be released on a disk. Ethnographic ensemble “Tuva” was established. Later, members of “Tuva” started their own musical bands. Musical programs were compiled as an ethnographic variety show – a principle that the public has been seeking for both in Tuva and abroad. Disks were realeased and artists started active touring in foreign countries. Boosting interest in World Music was marked with hallmark attention to the phenomenon of throat-singing and overtone music, and further evolution of Tuvan music has since been tightly linked to Western musical market. The author traces the peculiarities of such bands as “Huun Huur Tu”, “Yat-Kha”, etc. and remarks that the value of Tuvan music is not only in star performers shining on the Western skies, but in the rise of a stable community of people inspired by Tuvan music and culture, and seeking new ways of aesthetic and spiritual perception of

    We study dynamics of a probe p-brane and a test particle in the field background of fully localized solutions describing the source p-brane within the worldvolume of the source domain wall. We find that the probe dynamics in the background of the source p-brane in one lower dimensions is not reproduced, indicating that p-branes within the worldvolume of domain walls perhaps describe an exotic phase of p-branes in brane worlds. We speculate therefore that a (p+1)-brane where one of its longitudinal directions is along the direction transverse to the domain wall is the right describtion of the p-brane in the brane world with the expected properties.

    1992-01-01

    World grain production decreased 5% in 1991, which combined with the 90 million in population increase resulted in a 6.4% decline/person. This is the largest drop ever recorded. Currently world production is off 9% from the all time high in 1984 of 757 pounds/person. There are many signs that this trend will continue. Soil erosion continues to decrease the amount of available farm land, irrigation water logs fields, deforestation and desertification, air pollution, acid rain and increased ultra violet light form depleting ozone are all adding to the problem. Currently in the US 28 million acres idle as part of commodity supply management and 34 million acres are designated threatened and are in Conservation Reserve. However, even with this area put into production, the total area worldwide is still smaller than it was in 1984.

  6. Anaphora resolution without world knowledge

    Directory of Open Access Journals (Sweden)

    Leffa Vilson J.

    2003-01-01

    Full Text Available A typical problem in the resolution of pronominal anaphora is the presence of more than one candidate for the antecedent of the pronoun. Considering two English sentences like (1 "People buy expensive cars because they offer more status" and (2 "People buy expensive cars because they want more status" we can see that the two NPs "people" and "expensive cars", from a purely syntactic perspective, are both legitimate candidates as antecedents for the pronoun "they". This problem has been traditionally solved by using world knowledge (e.g. schema theory, where, through an internal representation of the world, we "know" that cars "offer" status and people "want" status. The assumption in this paper is that the use of world knowledge does not explain how the disambiguation process works and alternative explanations should be explored. Using a knowledge poor approach (explicit information from the text rather than implicit world knowledge the study investigates to what extent syntactic and semantic constraints can be used to resolve anaphora. For this purpose, 1,400 examples of the word "they" were randomly selected from a corpus of 10,000,000 words of expository text in English. Antecedent candidates for each case were then analyzed and classified in terms of their syntactic functions in the sentence (subject, object, etc. and semantic features (+ human, + animate, etc.. It was found that syntactic constraints resolved 85% of the cases. When combined with semantic constraints the resolution rate rose to 98%. The implications of the findings for Natural Language Processing are discussed.

  12. World Ships - Architectures & Feasibility Revisited

    Science.gov (United States)

    Hein, A. M.; Pak, M.; Putz, D.; Buhler, C.; Reiss, P.

    A world ship is a concept for manned interstellar flight. It is a huge, self-contained and self-sustained interstellar vehicle. It travels at a fraction of a per cent of the speed of light and needs several centuries to reach its target star system. The well- known world ship concept by Alan Bond and Anthony Martin was intended to show its principal feasibility. However, several important issues haven't been addressed so far: the relationship between crew size and robustness of knowledge transfer, reliability, and alternative mission architectures. This paper addresses these gaps. Furthermore, it gives an update on target star system choice, and develops possible mission architectures. The derived conclusions are: a large population size leads to robust knowledge transfer and cultural adaptation. These processes can be improved by new technologies. World ship reliability depends on the availability of an automatic repair system, as in the case of the Daedalus probe. Star systems with habitable planets are probably farther away than systems with enough resources to construct space colonies. Therefore, missions to habitable planets have longer trip times and have a higher risk of mission failure. On the other hand, the risk of constructing colonies is higher than to establish an initial settlement on a habitable planet. Mission architectures with precursor probes have the potential to significantly reduce trip and colonization risk without being significantly more costly than architectures without. In summary world ships remain an interesting concept, although they require a space colony-based civilization within our own solar system before becoming feasible.

  15. Nutritional rickets around the world.

    Science.gov (United States)

    Prentice, Ann

    2013-07-01

    Nutritional rickets is a major public health problem in many countries of the world. The disease is characterized by deformities of the long bones, enlargement of the wrists and costochondral junctions, hypotonia and, in infants, craniotabes and delayed fontanelle closure. Predominantly caused by severe vitamin D deficiency, rickets can also be associated with hypocalcemic seizures and cardiac failure. First presentation is typically at 6-24 months of age, although hypocalcemia may be evident in younger infants. In many affluent industrialized countries, the prevalence of rickets in the general population diminished after the introduction of clean-air legislation and dietary supplementation. However, in such countries, vitamin-D deficiency rickets has re-emerged in recent years, particularly among groups with limited exposure to UVB-containing sunshine. Infants at risk of rickets tend to be those whose mothers had poor vitamin D status during pregnancy and those exclusively breast-fed for a prolonged period with little skin exposure to UVB. In other countries of the world, the prevalence of rickets can be high, even in regions with abundant year-round UVB-containing sunshine. In general, this is also due to vitamin D deficiency related to limited sun exposure. However, reports from Africa and Asia suggest that there may be other etiological factors involved. Studies in South Africa, Nigeria, The Gambia and Bangladesh have identified rickets in children, typically 3-5 years old at first presentation, in whom plasma 25-hydroxyvitamin D concentrations are higher than those characteristic of primary vitamin D deficiency. Calcium deficiency has been implicated, and in some, but not all, disturbances of phosphate metabolism, renal compromise and iron deficiency may also be involved. Continuing studies of the etiology of nutritional rickets will provide evidence to underpin guidelines for the prevention and treatment of rickets world-wide. This article is part of a

  16. Colour Perception in Ancient World

    Nesterov, D. I.; Fedorova, M. Yu

    2017-11-01

    How did the human thought form the surrounding color information into the persistent semantic images of a mythological, pseudoscientific and religious nature? The concepts associated with colour perception are suggested. The existence of colour environment does not depend on the human consciousness. The colour culture formation is directly related to the level of the human consciousness development and the possibility to influence the worldview and culture. The colour perception of a person goes through the stages similar to the development of colour vision in a child. Like any development, the colour consciousness has undergone stages of growth and decline, evolution and stagnation. The way of life and difficult conditions for existence made their own adjustments to the development of the human perception of the surrounding world. Wars have been both a powerful engine of progress in all spheres of life and a great destructive force demolishing the already created and preserved heritage. The surrounding world has always been interesting for humans, evoked images and fantasies in the consciousness of ancient people. Unusual and inexplicable natural phenomena spawned numerous legends and myths which was reflected in the ancient art and architecture and, accordingly, in a certain manifestation of colour in the human society. The colour perception of the ancient man, his pragmatic, utilitarian attitude to colour is considered as well as the influence of dependence on external conditions of existence and their reflection in the colour culture of antiquity. “Natural Science” conducts research in the field of the colour nature and their authorial interpretation of the Hellenic period. Several authorial concepts of the ancient world have been considered.

    Directory of Open Access Journals (Sweden)

    José A. Tapia Granados

    1998-03-01

    general.During the last few decades, traffic injuries have become one of the leading causes of death and disability in the world. In urban areas, traffic congestion, noise, and emissions from motor vehicles produce subjective disturbances and detectable pathological effects. More than one billion people are exposed to harmful levels of environmental pollution. Because its combustion engine generates carbon dioxide (CO2, the automobile is one of the chief sources of the gases that are causing the greenhouse effect. The latter has already caused a rise in the average ambient temperature, and over the next decades it will predictably cause significant climatic changes whose consequences, though uncertain, are likely to be harmful and possibly catastrophic. Aside from the greenhouse effect, the relentless growth of parking zones, traffic, and the roadway infrastructure in urban and rural areas is currently one of the leading causes of environmental degradation. Urban development, which is nearly always "planned" around traffic instead of people, leads to a significant deterioration in the quality of life, while it also destroys the social fabric. Unlike the private automobile, public transportation, bicycles, and walking help reduce pollution, congestion, and traffic volume, as well as the morbidity and mortality resulting from injuries and ailments related to pollution. Non-automobile transportation also encourages physical activity--with its positive effect on general health--and helps reduce the greenhouse effect. The drop in traffic volume and the increased use of alternate means of transportation are thus an integrated health promotion policy which should become an inherent part of the movement for the promotion of healthy cities and of transportation policies and economic policy in general.

    The present paper aims to complete an earlier paper where the acoustic world was introduced. This is accomplished by analyzing the interactions which occur between the inhomogeneities of the acoustic medium, which are induced by the acoustic vibrations traveling in the medium. When a wave packet travels in a medium, the medium becomes inhomogeneous. The spherical wave packet behaves like an acoustic spherical lens for the acoustic plane waves. According to the principle of causality, there is an interaction between the wave and plane wave packet. In specific conditions the wave packet behaves as an acoustic black hole.

    2017-04-01

    Virtual reality has an increasingly significant role to play in teaching and research, but for geological applications realistic landscapes are required that contain sufficient detail to prove viable for investigation by both inquisitive students and critical researchers. To create such virtual landscapes, we combine DTM data with digitally modelled outcrops in the game engine Unity. Our current landscapes are fictional worlds, invented to focus on generation techniques and the strategic and spatial immersion within a digital environment. These have proved very successful in undergraduate teaching; however, we are now moving onto recreating real landscapes for more advanced teaching and research. The first of these is focussed on Rhoscolyn, situated within the Ynys Mon Geopark on Anglesey, UK. It is a popular area for both teaching and research in structural geology so has a wide usage demographic. The base of the model is created from DTM data, both 1 m LiDAR and 5 m GPS point data, and manipulated with QGIS before import to Unity. Substance is added to the world via models of architectural elements (e.g. walls and buildings) and appropriate flora and fauna, including sounds. Texturing of these models is performed using 25 cm aerial imagery and field photographs. Whilst such elements enhance immersion, it is the use of digital outcrop models that fully completes the experience. From fieldwork, we have a library of photogrammetric outcrops that can be modelled into 3D features using free (VisualSFM and MeshLab) and non-free (AgiSoft Photoscan) tools. These models are then refined and converted in Maya to create models for better insertion into the Unity environment. The finished product is a virtual landscape; a Rhoscolyn `world' that is sufficiently detailed to provide a base not only for geological teaching and training but also for geological research. Additionally, the `Rhoscolyn World' represents a significant tool for those students who are unable to attend

Our findings thus contribute to our understanding of entrepreneurship in context and challenge future research to explore how different forms of contexts are bridged in different settings to create varieties...

  6. String inspired brane world cosmology.

    2002-06-10

    We consider brane world scenarios including the leading correction to the Einstein-Hilbert action suggested by superstring theory, the Gauss-Bonnet term. We obtain and study the complete set of equations governing the cosmological dynamics. We find they have the same form as those in Randall-Sundrum scenarios but with time-varying four-dimensional gravitational and cosmological constants. By studying the bulk geometry we show that this variation is produced by bulk curvature terms parametrized by the mass of a black hole. Finally, we show there is a coupling between these curvature terms and matter that can be relevant for early universe cosmology.

    We study cosmological solutions in the dilatonic brane world models. The effective four-dimensional equations on the brane are analyzed for the models with one positive tension brane and two branes with tensions of opposite signs. Just as in the non-dilatonic brane case, the conventional Friedmann equations of the four-dimensional universe are reproduced to the leading order in matter energy density for the model with one brane and the introduction of a radion potential is required in order t...

    Mountain in its symbolic presentation can be considered as a world axis and place for alliance of three worlds: heavenly world, ours or middle world and underworld. Image of the three worlds represents also intellectual establishment, proportion and unity among Gods, Cosmos and Man. The three observation posts of the Megalithic Observatory Kokino actually are symbols of those three worlds in the ancient people's imagination, defining ritual activities. At the same time, they were used for organizing all agricultural and stock breeding activities of the early agricultural communities in the wider region surrounding the ancient observatory.

    2013-07-01

    Currently, small hydropower plants with a capacity of 10 MW, exist in 148 countries or territories worldwide. Four other countries have been identified with resource potential. This report aims to identify the development status and resource potential of small hydro in various countries, territories and regions throughout the world. Working with experts at the ground level to compile and share existing information, experiences and challenges, one comprehensive report was created. Decision-makers, stakeholders and potential investors clearly need this comprehensive information to more effectively promote small hydropower as a renewable and rural energy source for sustainable development and to overcome the existing development barriers. The findings of this report show that small hydropower potential globally is approximated at almost 173 GW. The figure is arrived by totaling data from a wide range of sources with potential compromise of data integrity to varying degrees. For example, research data on economically feasible potential were more readily available in developed countries than those in the least developed or developing countries. More than half of the world's known hydropower potential is located in Asia, around one third can be found in Europe and the Americas. It is possible in the future that more small hydropower potential might be identified both on the African and American continents. The installed small hydropower capacity (up to 10 MW) is estimated to be 75 GW in 2011/2012. The report provides detailed data for each country/region, including recommendations on the national, regional and international level.

  12. MODELING WORLD BIOENERGY CROP POTENTIAL

    Hagiwara, Kensuke; Hanasaki, Naota; Kanae, Shinjiro

    Bioenergy is regarded as clean energy due to its characteristics and expected to be a new support of world energy de¬mand, but there are few integrated assessments of the potential of bioenergy considering sustainable land use. We esti¬mated the global bioenergy potential with an integrated global water resources model, the H08. It can simulate the crop yields on global-scale at a spatial resolution of 0.50.5. Seven major crops in the world were considered; namely, maize, sugar beet, sugar cane, soybean, rapeseed, rice, and wheat, of which the first 5 are commonly used to produce biofuel now. Three different land-cover types were chosen as potential area for cultivation of biofuel-producing crop: fallow land, grassland, and portion of forests (excluding areas sensitive for biodiversity such as frontier forest). We attempted to estimate the maximum global bioenergy potential and it was estimated to be 1120EJ. Bioenergy potential depends on land-use limitations for the protection of bio-diversity and security of food. In another condition which assumed more land-use limitations, bioenergy potential was estimated to be 70-233EJ.

  13. The Stuff of Other Worlds

    Extraterrestrial material eternally rains down on Earth. Meteorites flare in the night sky. Cosmic rays plow into Earth's atmosphere, creating invisible bursts of secondary particles. These processes began when the Earth formed in the primordial solar system and have continued ever since, indifferent to the exceedingly recent presence of human intelligence. For us to seek out stuff of other worlds, in contrast, takes a great deal of determined ingenuity. First we have to send a spacecraft somewhere else in the solar system. Indigenous material has to be collected and then brought back to Earth without exposure to conditions that might significantly alter it. The material must undergo meaningful scientific analysis. Most important, part of the material is preserved intact for future investigations. Beginning with bringing back Moon rocks, and now moving onward in the form of new missions to capture the hot thin solar wind and cold thin atmosphere of comets, extraterrestrial sample return takes place on the cutting edge of scientific technology. Sample return is also the fulcrum of an energetic debate about how to do planetary science missions. Scientists and engineers are debating whether to rely on remote sensing and in situ analysis, or to plan missions to undertake sample return. The latter is definitely more expensive on a per mission basis, and is usually technologically more challenging. But for an initially high investment of money and technology, bringing the stuff of other worlds back to Earth yields an incomparable return in scientific results.

    A free, world-class education for anyone, anywhere: this is the goal of the Khan Academy, a passion project that grew from an ex-engineer and hedge funder's online tutoring sessions with his niece, who was struggling with algebra, into a worldwide phenomenon. Today millions of students, parents, and teachers use the Khan Academy's free videos and software, which have expanded to encompass nearly every conceivable subject; and Academy techniques are being employed with exciting results in a growing number of classrooms around the globe. Like many innovators, Khan rethinks existing assumptions and imagines what education could be if freed from them. And his core idea - liberating teachers from lecturing and state-mandated calendars and opening up class time for truly human interaction - has become his life's passion. Schools seek his advice about connecting to students in a digital age, and people of all ages and backgrounds flock to the site to utilise this fresh approach to learning. In THE ONE WORLD SCHOOL...

    Ditzler, Mark A.

    2014-01-01

    RNA world theories figure prominently in many scenarios for the origin and early evolution of life. These theories posit that RNA molecules played a much larger role in ancient biology than they do now, acting both as the dominant biocatalysts and as the repository of genetic information. Many features of modern RNA biology are potential examples of molecular fossils from an RNA world, such as the pervasive involvement of nucleotides in coenzymes, the existence of natural aptamers that bind these coenzymes, the existence of natural ribozymes, a biosynthetic pathway in which deoxynucleotides are produced from ribonucleotides, and the central role of ribosomal RNA in protein synthesis in the peptidyl transferase center of the ribosome. Here, we uses both a top-down approach that evaluates RNA function in modern biology and a bottom-up approach that examines the capacities of RNA independent of modern biology. These complementary approaches exploit multiple in vitro evolution techniques coupled with high-throughput sequencing and bioinformatics analysis. Together these complementary approaches advance our understanding of the most primitive organisms, their early evolution, and their eventual transition to modern biochemistry.

    1989-10-21

    The number of persons suffering from anaemia in the world is estimated at fifty million to one billion. Most of these are children, since they are more vulnerable than adults as regards nutrition and they constitute the bulk of the population in developing countries. Depending on the region, the prevalence of anaemia among children varies from 15 to 25 p. 100 in Latin America and Indonesia and from 70 to 80 p. 100 in Africa south of the Sahara desert and in India. Anaemia results from multiple deficiencies simultaneously involving iron, folic acid and proteins. The responsibility of each of these deficiencies is difficult to determine and probably varies from one region to another. The causes of these deficiencies are multiple; they include insufficient intake, inadequate absorption, increased needs and excessive losses. The only efficient measure would be an improvement in the level of life.

    Full Text Available Catalysis provides orderly prebiotic synthesis and eventually its evolution into autocatalytic (self-reproduction systems. Research on homogeneous catalysis is concerned mostly with random peptide synthesis and the chances to produce catalytic peptide oligomers. Synthesis of ribose via formose reaction was found to be catalysed by B(OH4−, presumably released by weathering of borate minerals. Oxide and clay mineral surfaces provide catalytic sites for the synthesis of oligopeptides and oligonucleotides. Chemoautotrophic or iron-sulphur-world theory assumes that the first (pioneer organisms developed by catalytic processes on (Fe/NiS particles formed near/close hydrothermal vents. The review provides an overlay of possible catalytic reactions in prebiotic environment, discussing their selectivity (regioselectivity, stereoselectivity as well as geological availability of catalytic minerals and geochemical conditions enabling catalytic reactions on early Earth.

    Arai, Masato; Blaschke, Filip; Eto, Minoru; Sakai, Norisuke

    2017-12-01

    We present a field theoretical model unifying grand unified theory (GUT) and brane world scenario. As a concrete example, we consider S U (5 ) GUT in 4 +1 dimensions where our 3 +1 dimensional spacetime spontaneously arises on five domain walls. A field-dependent gauge kinetic term is used to localize massless non-Abelian gauge fields on the domain walls and to assure the charge universality of matter fields. We find the domain walls with the symmetry breaking S U (5 )→S U (3 )×S U (2 )×U (1 ) as a global minimum and all the undesirable moduli are stabilized with the mass scale of MGUT. Profiles of massless standard model particles are determined as a consequence of wall dynamics. The proton decay can be exponentially suppressed.

    2006-01-01

    Full Text Available Globalisation has proofed its self as a very spectacular phenomenon until no one may deny its impacts, but on the other hand, it reflexively suggests localization of the global. In this context, religion is not exclusion. It remains believed however, that religion still has its formula for solving the problems that emerged from globalisation. Scholars have devoted attempts to propose new ideas for this challenge. Local interpretations of symbols representing “global” Islam, for instance, increasingly grow in line with the growth of Islamic revival. This has drawn very much attention and responses from Muslims, whether to protest against or support for the new idea. The present edition of the journal is designed to more deeply explore the current issues from Muslim world, whether as very local phenomena or in a more global context.

    Full Text Available The article shows that Indian-Arab relations are very complex and are affected by many positive and negative factors. From a political point of view, the Middle East does not rank high in the priorities of India’s modern foreign policy. In the bipolar period, India tried to strengthen ties with all developing countries with the aim of becoming a leader of the South. In this respect, the region (especially Egypt in the 1950-1970s played a special role. Now India pays attention mainly to vital actors. Policy of non-interference in regional conflicts is typical for India. Delhi has focused on the developing of ties with the countries of the Persian Gulf, due mainly to economic reasons that are of primary importance to India. This subregion is a major supplier of hydrocarbons to India, that is extremely vital for further rapid economic growth of the country (oil and gas account for about a third of India’s imports. In addition to this, millions of Indian citizens live in the Persian Gulf, and India (due to them has become the world leader by the volume of migrant remittances. The largest semi-peripheral countries, among which India should be mentioned particularly, began to play a special role in the new world system. However, the politics of balancing is characteristic for India both on global level as well as on regional one. But a real great power (and the desire to obtain such high status was always the main goal for an Asian giant should demonstrate a clear vision of global and regional issues, play an active role and offer its own solution of different conflicts and contradictions.

  16. Culture collections over the world.

    Science.gov (United States)

    Smith, David

    2003-06-01

    Culture collections have the crucial role of providing the authenticated biological material upon which high quality research is based. Importantly, they serve as repositories for strains as part of patent deposits, providers of safe and confidential services to store key organisms for research and industry, and sources of organisms cited in scientific papers that can be used in the confirmation of results and for further study. The demands upon culture collections change as new technologies and uses of organisms are discovered. Many are becoming Biological Resource Centres, as defined by the OECD Biological Resource Centre (BRC) Initiative, in that they operate according to international quality criteria, carry out essential research, enhance the value and applications of strains and provide a vital information resource. In a changing international scientific environment, many collections are under threat of extinction because of inadequate funding, changing government support strategies and the cost of new technologies. We are also suffering a decline in the number of biosystematists, who are needed to form a sound base for molecular technologies and to aid in identifying, and characterizing microbial diversity. In this environment, collections must work together to make the best use of new technologies and to contribute to the description of the 1.4 million fungi yet to be discovered. At the current rate, this will take 700 years. New technologies and novel ways of funding this task must be engaged and, above all, scientists must collaborate. Common policies are necessary to address the regulatory demands on collections, to control access to dangerous organisms, and, in particular, to enforce the Convention on Biological Diversity. Countries that hold the majority of biodiversity require support in building the facilities required to explore their hidden resource.

    Full Text Available The article points out that the progressive deterioration of the social and environmental situation on the planet and the emergence of the real threat of anthropo-ecological catastrophe necessitate the abandoning of the current model of civilizational development and the formation (first in theory and then in practice of an ultimately new one. This innovative strategy, which means taking account of the main socio-natural contradiction, is called a sustainable development strategy. This new form of civilizational development must become rationally governed on a planetary scale, thus providing the survival and temporal continuation of the existence of humans and biosphere. The authors regard sustainable development as a vitally important (later on - dominating orientation of international, political and global processes. This vision makes it crucially important to embed this conception into the proper scientific disciplines and research fields. The authors make use of the A.D. Bogaturov's conceptualization approach for the scientific discipline of world politics and consider the latter as an evolutionary form of global political development. The real global integrity of the world political system serves as a global attractor of this evolutionary transformation, and this aspect represents the specific pattern of all global processes. It is supposed that these processes will unfold through transition to sustainable development. The development of the global system of political actorship is considered a fundamental process within the growth of overall complexity of the global political structure. In the evolutionary sustainable development perspective it should result in the formation of an integral subject of global politics and global activity. The article shows that the dominating state-centric approach reproduces the political model of unsustainable development, which is characterized by archaic prerequisites of political realism, spontaneous

    The comments of the Director of Foreign Affairs for the China State Family Planning Commission reflect satisfaction with the achievements at the Fourth World Conference on Women held in Beijing. It is posited that the historic documents from the conference reflect the common aspirations of all women in the world for equality, development, and peace. The conference's focus on social development for women has been translated in China into a "vigorous" IEC campaign. China is developing integrated approaches to family planning in rural areas. The approach aims to help rural women to become economically independent before achieving equality within the family and society. A National Conference on Integrated Programs was held in Sichuan province. Examples of integrated programs in Sichuan, Jilin, and Jiangsu were described for conference participants. The example is given of how poor rural women in Deyang Prefecture, Sichuan province, have received credit for income generation and access to skill development and literacy classes. Continuous economic and social development are important for achieving "poverty eradication and the liberation of women." Sustainable development involves use of resources, environmental protection, the reasonable change in consumption patterns, and transitional changes in modes of production. The concept of reproductive health means Chinese family planning workers must meet higher standards. Future plans include intensifying the IEC program in meeting the comprehensive biological, psychological, and social reproductive health needs of women. Respect must be given to the fertility intentions and reproductive rights of wives and husbands. "In China, voluntary choice of childbearing should be guided by the fertility policy formulated by the government." Training of family planning workers should be intensified to include training in public health, reproductive theory, contraception, and the techniques of interpersonal communication. Some provinces

    Full Text Available This story is about a kind of pilgrimage, which is connected to the course of events which occurred in Częstochowa on 22 September 1942. In the morning, the German Captain Degenhardt lined up around 8,000 Jews and commanded them to step either to the left or to the right. This efficient judge from the police force in Leipzig was rapid in his decisions and he thus settled the destinies of thousands of people. After the Polish Defensive War of 1939, the town (renamed Tschenstochau had been occupied by Nazi Germany, and incorporated into the General Government. The Nazis marched into Częstochowa on Sunday, 3 September 1939, two days after they invaded Poland. The next day, which became known as Bloody Monday, approximately 150 Jews were shot deadby the Germans. On 9 April 1941, a ghetto for Jews was created. During World War II about 45,000 of the Częstochowa Jews were killed by the Germans; almost the entire Jewish community living there.The late Swedish Professor of Oncology, Jerzy Einhorn (1925–2000, lived in the borderhouse Aleja 14, and heard of the terrible horrors; a ghastliness that was elucidated and concretized by all the stories told around him. Jerzy Einhorn survived the ghetto, but was detained at the Hasag-Palcery concentration camp between June 1943 and January 1945. In June 2009, his son Stefan made a bus tour between former camps, together with Jewish men and women, who were on this pilgrimage for a variety of reasons. The trip took place on 22–28 June 2009 and was named ‘A journey in the tracks of the Holocaust’. Those on the Holocaust tour represented different ‘pilgrim-modes’. The focus in this article is on two distinct differences when it comes to creed, or conceptions of the world: ‘this-worldliness’ and ‘other- worldliness’. And for the pilgrims maybe such distinctions are over-schematic, though, since ‘sacral fulfilment’ can be seen ‘at work in all modern constructions of travel, including

  1. The Next World War: World-System Cycles and Trends

    Directory of Open Access Journals (Sweden)

    1995-08-01

    Full Text Available This essay places the contemporary period of global development in long-run historical perspective, elaborates a model of world-system cycles and trends, and discusses the main structural forces influencing the probability of future war among core powers. The possible continuation of the cycle of hegemonic rivalry is discussed in terms of the similarities and differences between the coming three decades and earlier periods in which a declining hegemon was challenged by upwardly mobile states. Possible bids for economic and political hegemony by Japan, Germany, China and the United States are discussed, as are the possibilities for different coalitions in East Asia and Europe. The phenomenon of bloc formation is discussed in a long-term perspective that includes earlier periods of colonial empire and "commonwealth." We conclude that there is a significantly high probability that warfare among core states could occur in the 2020s. The prospects for global state formation within the next three decades are considered. We recommend a combination of the build-up of U.N. peace-keeping forces and the continuation of U.S. military strength as the least worst and most feasible solution to the problem of avoiding nuclear holocaust in the 2020s.

  2. World's Biggest Astronomy Event on the World-Wide

    `Astronomy On-Line' will connect students all over Europe Astronomy On-Line is a major, all-European project that will take place in conjunction with the 4th European Week for Scientific and Technological Culture later this year. It is based on intensive use of the World-Wide-Web (WWW) and represents the first large-scale attempt in the world to bring together pupils and their teachers all over one continent to explore challenging scientific questions, using modern communication tools, both for obtaining and for communicating information. The programme will be carried out in a collaboration between the European Association for Astronomy Education (EAAE) [1] and the European Southern Observatory, and together with the European Commission (EC). The active phase of Astronomy On-Line will start on October 1 and reach a climax on November 18 - 22, 1996 . What is `Astronomy On-Line'? In this project, a large number of students and their teachers at schools all over Europe, together with professional and amateur astronomers and others interested in astronomy, will become associated in a unique experience that makes intensive use of the vast possibilities of the World-Wide-Web (WWW). Although the exact number of participants will not be known until the beginning of October, it is expected to run into thousands, possibly many more. The unusual size and scope of Astronomy On-Line will contribute to make it an important all-European media event. The central idea is that the participants, through the WWW, will `meet' in a `marketplace' where a number of different `shops' will be available, each of which will tempt them with a number of exciting and educational `events', carefully prepared to cater for different age groups, from 12 years upwards. The events will cover a wide spectrum of activities, some of which will be timed to ensure the proper progression of this very complex project through its main phases.

    To determine the incidence, severity and nature of injuries sustained during the Rugby World Cup (RWC) 2015 together with the inciting events leading to the injuries. A prospective, whole population study. 639 international rugby players representing 20 countries. The study protocol followed the definitions and procedures recommended in the consensus statement for epidemiological studies in rugby union; output measures included players' age (years), stature (cm), body mass (kg) and playing position, and the group-level incidence (injuries/1000 player-hours), mean and median severity (days-absence), location (%), type (%) and inciting event (%) for match and training injuries. Incidence of injury was 90.1 match injuries/1000 player-match-hours (backs: 100.4; forwards: 81.1) and 1.0 training injuries/1000 player-training-hours (backs: 0.9; forwards: 1.2). The mean severity of injuries was 29.8 days-absence (backs: 30.4; forwards: 29.1) during matches and 14.4 days-absence (backs: 6.3; forwards: 19.8) during training. During matches, head/face (22.0%), knee (16.2%), muscle-strain (23.1%) and ligament-sprain (23.1%) and, during training, lower limb (80.0%) and muscle-strain (60.0%) injuries were the most common locations and types of injury. Being-tackled (24.7%) was the most common inciting event for injury during matches and rugby-skills-contact activities (70.0%) the most common during training. While the incidence, nature and inciting events associated with match injuries at RWC 2015 were similar to those reported previously for RWCs 2007 and 2011, there were increasing trends in the mean severity and total days-absence through injury.

    Full Text Available Existe un número cada vez mayor de niños que utilizan dispositivos tecnológicos personales, tales como el teléfono móvil, por distintos motivos. Por un lado, pretenden autodefinirse y, por otro, crean redes sociales fuera del entorno familiar. La red que se está creando está siendo mucho más influyente sobre ellos que, por ejemplo, la publicidad; es decir, se ha creado una enorme dependencia y una mayor confianza en fuentes no tradicionales. Estos jóvenes, de entre 16 y 30 años, tienen la oportunidad de elegir entre una gran variedad de iniciativas en España, tales como Tuenti, Keteké, Itsmy.com o la futura Blyk. No obstante, se debe prestar atención a la responsabilidad social que se deriva de este fenómeno y revisar las leyes vigentes. Además, las asociaciones de consumidores y otros grupos, así como las autoridades, deben adaptarse a esta nueva situación para proteger los intereses de los consumidores.

    The North Pacific right whale (Eubalaena japonica) was heavily exploited by both nineteenth century whaling and recent (1960s) illegal Soviet catches. Today, the species remains extremely rare especially in the eastern North Pacific. Here, we use photographic and genotype data to calculate the first mark–recapture estimates of abundance for right whales in the Bering Sea and Aleutian Islands. The estimates were very similar: photographic = 31 (95% CL 23–54), genotyping = 28 (95% CL 24–42). We also estimated the population contains eight females (95% CL 7–18) and 20 males (95% CL 17–37). Although these estimates may relate to a Bering Sea subpopulation, other data suggest that the total eastern North Pacific population is unlikely to be much larger. Its precarious status today—the world's smallest whale population for which an abundance estimate exists—is a direct consequence of uncontrolled and illegal whaling, and highlights the past failure of international management to prevent such abuses.

    2014-02-01

    A progressive erosion of the democratic space appears as one of the emerging challenges in global health today. Such delimitation of the political interplay has a particularly evident impact on the unique public interest function of the World Health Organization (WHO). This paper aims to identify some obstacles for a truly democratic functioning of the UN specialized agency for health. The development of civil society's engagement with the WHO, including in the current reform proposals, is described. The paper also analyses how today's financing of the WHO--primarily through multi-bi financing mechanisms--risks to choke the agency's role in global health. Democratizing the public debate on global health, and therefore the role of the WHO, requires a debate on its future role and engagement at the country level. This desirable process can only be linked to national debates on public health, and the re-definition of health as a primary political and societal concern.

    2015-01-01

    Full Text Available The world population reached 7 billion in 2012, which is 6 billion more than in 1800. This remarkable population growth is the result of several factors like advances in the medical, technological and public health systems resulting in the control and treatment of communicable diseases, the control of pandemics, the end of large-scale wars, improvements in living conditions and the revolutions in the field of agriculture. Because of all these factors, there has been a considerable improvement in the life expectancy of human beings. There is also an alarming reduction in fertility rates. The combination of declining fertility rate and augmented life expectancies has led to a change in the demographics of the population with the strata of older individuals growing faster than the younger individuals. The aging of populations is poised to become the next global public health challenge. Advances in medicine and socioeconomic development have substantially reduced mortality and morbidity rates due to infectious conditions and, to some extent, non-communicable diseases. These demographic and epidemiological changes, coupled with rapid urbanization, modernization, globalization, and accompanying changes in risk factors and lifestyles, have increased the prominence of chronic non-infective conditions. Health systems need to find effective strategies to extend health care and to respond to the needs of older adults. This review highlights the pathophysiology of aging, biological and physiological changes, impact of aging on health, epidemiological transitions, multi-morbidity in elderly and challenges for health care system.

It has transformed the way we socialize, conduct business, and even changed the way we do science. But unfortunately, the number of available Internet addresses has not grown at the same place to accommodate these changes.   The number of Internet addresses is fixed because of the way the Internet operates: data is routed through the Internet in packets that use numeric addresses to encode its origin and its destination.

    A lighting system using light-emitting diodes, and privately financed by a Canadian engineering professor at the University of Calgary, has been set up in a village in Nepal in 2000. Since then, through the efforts of the 'Light Up The World' Foundation, established by Dr. Irvine-Halliday, projects have lit up thousands of homes in the Philippines, India, Afghanistan, the Galapagos Islands, Mexico, Sri Lanka, and Angola. Although the goal of the project is primarily to provide lighting for reading and writing for school-children, the project has been the source of many other advantages; creation of enterprise, increased employment, enhanced income, gender equality, and improvements in health and safety among them. Since LED lamps in most cases replace kerosene lamps, the system also has significant environmental benefits. The system as originally envisioned creates electricity by pedal-powered generator, or by solar panels connected to a battery, depending on what is available at each home. Each home is connected to the power supply and supplied with low-energy diode lamps. The lights are extremely efficient and many homes can be equipped with them using less energy than it takes to power a single 100-watt light bulb. 5 photos.

    In the Third World millions of malnourished, overworked women and girls are excluded from the circles of power, and they are out of touch with the other half of humanity approaching 5 billion. In the villages of South Asia they face poverty, constant toil, and continual pregnancies. The plight of those women is an scathing indictment on how these societies value their female citizens. There can be no long-term development anywhere on this planet unless women are fully involved in the design of the societies. To be involved they must be healthy, respected citizens. The centrality members is not clearly enough understood or recognized. Maternal mortality is too often the end-result of a life diminished by discrimination from the moment of birth to early marriage. If women are to be healthy they must have increased access to education, training, credit, health care, and legal protection. The poorer women are, the more vulnerable they are to exploitation from unfair labor practices, prostitution, and physical violence. In Peru, 70% of all crimes reported comprise women beaten by their partners. In India, police recorded 1,786 dowry deaths in 1987, but a women's action group estimates the figure is over 1000 in Gujarat state alone. Women must be brought into the mainstream of our societies. One way of doing so is to use the model of the Convention of the Elimination of All Forms of Discrimination Against Women adopted by the UN General Assembly 10 years ago that gives legal guidelines to enhance women's rights and status.

    2015-12-01

    Full Text Available This article is focused on the works that derive from the field of study about peace and, more specifically, the theory relating to imperfect peace, developed by a group of researchers some years ago. Francisco A. Muñoz, researcher from Granada (Andalusia, Spain was the originator of this theory at the beginning of the 2000 and afterwards, it was applied by other academics to different fields related to the study of peace. The central theme of our work is to analyse the cultural field and the mediating role of cultures in the peaceful regulation of conflicts, considering that all human activity has cultural connotations. We will talk about cultures, not as isolated entities that are geographically delimited, but as interrelating spaces that give rise to social structures in which changes and transformations, ideas and ways of acting (ranging from the personal to the social, the political and the international occur that may be common, shared and compatible. These cultural aspects will be studied from the method or perspective called Peace Research, discipline which allow us analysing, among others, the social and culture phenomena that form part of historical processes in different places and times. The main topic will be focussed on the religious aspect, as one of the cultural identifying and its influence on identities, although other cultural dimensions could be studied (economical, political, environmental or educational. Additionally, we are setting our analysis on the world stage, where cultures and all human activity unfold today. Current globalization is a process that affects most of our reality: economic models, the market, nationalisms, international relations, relationships between cultures and religions, gender relations, education, etc. In all these spheres, problems and conflicts are generated that cannot be understood if we do not consider them to be ‘global problems’.

    Full Text Available Penguins identify their mate or chick by an acoustic signal, the display call. This identification is realized in a particularly constraining environment: the noisy world of a colony of thousands of birds. To fully understand how birds solve this problem of communication, we have done observations, acoustic analysis, propagation and playback experiments with 6 species of penguins studied in the field. According to our results, it appears that penguins use a particularly efficient ''anti-confusion'' and ''anti-noise'' coding system, allowing a quick identification and localization of individuals on the move in a noisy crowd.Os pingüins identificam seu parceiro ou seu filhote através de um sinal acústico, o grito de exibição.

    2016-12-01

    Every drop of seawater contains fantastically diverse groups of microbes that control key biogeochemical processes in the ocean and determine the habitability of our planet. The challenge is to scale from this world of individual cells to ecosystem function and ultimately to ocean basin processes. Our work begins with microscopic marine diatoms because they are responsible for about twenty percent of the photosynthesis that occurs on Earth each year, they form the base of highly productive marine food webs, and they help regulate past and current fluxes of CO2 into the ocean. Diatoms evolved in a dilute environment where they are never free from the influences of other microbes. We explore the specifics of these interactions via model diatom/bacteria systems that can be manipulated in the laboratory - one includes an antagonistic bacterium that inhibits the growth of diatoms and a second includes a synergistic bacterium that enhances the growth of diatoms. We scale up from the cellular level to population-level interactions through use of our continuous flow cytometer, SeaFlow, which taps into a ship's seawater intake system to provide a continuous read-out of abundance, size and type of the smallest phytoplankton. We use this data to estimate division rates and mortality rates of these phytoplankton across thousands of kilometers of ocean basins. We tie these scales together with genomic approaches in both laboratory experiments and in open ocean field studies to document how interactions with the environment and between microbes drive specific adaptations. Our ultimate goal is to understand how microbial communities will respond to and will help shape future ocean conditions.

    This article describes Japan's celebration of World Population Day, and provides excerpts from speeches at the symposium held on July 8, 1998. The symposium, in Tokyo, was attended by about 300 people. The Chairman of JOICFP gave the opening address. The executive director of UNFPA congratulated Japan for its efforts in the field of population awareness and noted Japan's self-sufficiency despite its importation of 40% of its food and most of its raw materials. A keynote address was delivered by the president of CPE and the former UN Secretary General, who stressed income inequities in the 66% of developing countries within the 185 UN member states. The UN has been promoting sustainable development, but is facing the issue of limited arable land and population growth. The Tutsi and Hutus are fighting due to population based issues. The emphasis should be on women's reproductive rights and protection of women's human rights. 1998 is the 50th year of human rights; progress has been made. The UNFPA Goodwill Ambassador spoke about the disparity between the rich and poor in the Philippines. A small donation reaps incredible progress. Manila has high levels of adolescent childbearing. Men appear to be unaware of the disadvantages of childbearing too early. Rural areas are dominated by strict Roman Catholic beliefs. Manila has commercial sex workers who provide services to Japanese men. The 1998 Kato Award was given to women who raised awareness about coercion in the sex trade and female genital mutilation. The economic situation in Japan creates even greater need to promote family planning and reproductive health.

    Pagin, Peter

    2017-01-01

    In Our Knowledge of the Internal World, Robert Stalnaker describes two opposed perspectives on the relation between the internal and the external. According to one, the internal world is taken as given and the external world as problematic, and according to the other, the external world is taken as given and the internal world as problematic. Analytic philosophy moved from the former to the latter, from problems of world-construction to problems of self-locating beliefs. I argue in this paper that these problems are equivalent: both arise because experience and objective, external facts jointly underdetermine their relation. Both can be seen as a problem of expressive completeness; of the internal language in the former case, and of the non-indexical language in the second.

  1. Deploying Embodied AI into Virtual Worlds

    Science.gov (United States)

    Burden, David J. H.

    The last two years have seen the start of commercial activity within virtual worlds. Unlike computer games where Non-Player-Character avatars are common, in most virtual worlds they are the exception — and until recently in Second Life they were non-existent. However there is real commercial scope for Als in these worlds — in roles from virtual sales staff and tutors to personal assistants. Deploying an embodied AI into a virtual world offers a unique opportunity to evaluate embodied Als, and to develop them within an environment where human and computer are on almost equal terms. This paper presents an architecture being used for the deployment of chatbot driven avatars within the Second Life virtual world, looks at the challenges of deploying an AI within such a virtual world, the possible implications for the Turing Test, and identifies research directions for the future.

    2016-11-01

    Full Text Available Taking tourists’ perspective rather than destination offerings as its core concept, this study introduces “perceived destination brand worldness” as a variable. Perceived destination brand worldness is defined as the positive perception that a tourist has of a country that is visited by tourists from all over the world. Then, the relationship between perceived destination brand worldness and intention to revisit is analyzed using partial least squares regression. This empirical study selects Taiwanese tourists as its sample, and the results show that perceived destination brand worldness is a direct predictor of intention to revisit. In light of these empirical findings and observations, practical and theoretical implications are discussed.

    This article discusses materials and results of the World Geothermal Congress that was held in Melbourne (Australia) from April 19 to April 25, 2015. Information on the extent and technological features of utilization of geothermal resources for heat supply and power production, as well as in other economic areas, is given. A stable growth in the capacity and number of geothermal power systems that is determined by ecological cleanliness, economic efficiency, and the highest (among renewable energy sources) indicators of installed capacity utilization is shown. It was noted that combined schemes of geothermal power plants (GPPs), such as turbine units of different type (binary units, units with one or two separation pressures, etc.), have become more frequently used to increase the efficiency of utilization of geothermal heat carrier. Actual data determining room heating systems with the total worldwide capacity of nearly 50000 MW thermal (MWt) as the most currently significant segment of consumption of geothermal waters are given. In addition, geothermal resources are also utilized in soil pumps, balneological and sports basins, greenhouse complexes, and other manufactures. It was noted that geological studies were carried out in more than 40 countries, with the development of methods of simulation of tanks for the existing and new geothermal fields. Trends of development and the role of geothermal power engineering in the energy supply of many countries are shown. It was shown that prospects for the development of geothermal power generation are significantly associated with utilization of low-temperature geothermal sources in binary power generating units, as well as with the increase in installed capacity of operating geothermal power plants (GPPs) without drilling additional wells, i.e., by using waste geothermal heat carrier in binary-cycle or combined-cycle power plants.

  13. The ribosome challenge to the RNA world.

    Science.gov (United States)

    Bowman, Jessica C; Hud, Nicholas V; Williams, Loren Dean

    2015-04-01

    An RNA World that predated the modern world of polypeptide and polynucleotide is one of the most widely accepted models in origin of life research. In this model, the translation system shepherded the RNA World into the extant biology of DNA, RNA, and protein. Here, we examine the RNA World Hypothesis in the context of increasingly detailed information available about the origins, evolution, functions, and mechanisms of the translation system. We conclude that the translation system presents critical challenges to RNA World Hypotheses. Firstly, a timeline of the RNA World is problematic when the ribosome is incorporated. The mechanism of peptidyl transfer of the ribosome appears distinct from evolved enzymes, signaling origins in a chemical rather than biological milieu. Secondly, we have no evidence that the basic biochemical toolset of life is subject to substantive change by Darwinian evolution, as required for the transition from the RNA world to extant biology. Thirdly, we do not see specific evidence for biological takeover of ribozyme function by protein enzymes. Finally, we can find no basis for preservation of the ribosome as ribozyme or the universality of translation, if it were the case that other information transducing ribozymes, such as ribozyme polymerases, were replaced by protein analogs and erased from the phylogenetic record. We suggest that an updated model of the RNA World should address the current state of knowledge of the translation system.

  17. A local-world evolving hypernetwork model

    Yang, Guang-Yong; Liu, Jian-Guo

    2014-01-01

    Complex hypernetworks are ubiquitous in the real system. It is very important to investigate the evolution mechanisms. In this paper, we present a local-world evolving hypernetwork model by taking into account the hyperedge growth and local-world hyperedge preferential attachment mechanisms. At each time step, a newly added hyperedge encircles a new coming node and a number of nodes from a randomly selected local world. The number of the selected nodes from the local world obeys the uniform distribution and its mean value is m. The analytical and simulation results show that the hyperdegree approximately obeys the power-law form and the exponent of hyperdegree distribution is γ = 2 + 1/m. Furthermore, we numerically investigate the node degree, hyperedge degree, clustering coefficient, as well as the average distance, and find that the hypernetwork model shares the scale-free and small-world properties, which shed some light for deeply understanding the evolution mechanism of the real systems.

  18. Learning, Teaching and Ambiguity in Virtual Worlds

    Science.gov (United States)

    Carr, Diane; Oliver, Martin; Burn, Andrew

    What might online communities and informal learning practices teach us about virtual world pedagogy? In this chapter we describe a research project in which learning practices in online worlds such as World of Warcraft and Second LifeTM (SL) were investigated. Working within an action research framework, we employed a range of methods to investigate how members of online communities define the worlds they encounter, negotiate the terms of participation, and manage the incremental complexity of game worlds. The implications of such practices for online pedagogy were then explored through teaching in SL. SL eludes simple definitions. Users, or "residents", of SL partake of a range of pleasures and activities - socialising, building, creating and exhibiting art, playing games, exploring, shopping, or running a business, for instance. We argue that the variable nature of SL gives rise to degrees of ambiguity. This ambiguity impacts on inworld social practices, and has significant implications for online teaching and learning.

    In this work we investigate the entropic information on thick brane-world scenarios and its consequences. The brane-world entropic information is studied for the sine-Gordon model and hence the brane-world entropic information measure is shown to be an accurate way for providing the most suitable range for the bulk AdS curvature, in particular from the informational content of physical solutions. Besides, the brane-world configurational entropy is employed to demonstrate a high organisational degree in the structure of the configuration of the system, for large values of a parameter of the sine-Gordon model but the one related to the AdS curvature. The Gleiser and Stamatopoulos procedure is finally applied in order to achieve a precise correlation between the energy of the system and the brane-world configurational entropy.

    Full Text Available In the article the influence of the existing world currency system on the international financial relations is considered, the retrospective analysis of the existing four currency systems is carried out. The change of a world currency order is justified. The concept of the new international currency standard based on division of functions of money between separate financial instruments of one currency is offered. The functional communications between financial instruments are revealed. The comparison of function of money and independent tools of new world currency is carried out, it is supposed that tools are actually completely capable to carry out all functions of money. Therefore, the new international currency standard is based on division of these functions between separate tools and can be defined as polytool. The general function chart of the polytool world currency standard including their functional connections between reserve tool, reverse tool and credit as well as their characteristics which should determine the activity of world reserve system. Prerequisites of replacement of the Jamaican currency system by the alternative are proved; the most perspective way of transition to the polytool standard is revealed; the additional functions of the polytool standard are designated – stimulation of issuers of the leading world currencies to refuse harmful policy of competitive devaluation, stimulation of integration of the countries and creation of collective currencies (currency zones and associations that will significantly increase financial stability of world economy.

  10. World knowledge affects prediction as quickly as selectional restrictions: Evidence from the visual world paradigm.

    Science.gov (United States)

    Milburn, Evelyn; Warren, Tessa; Dickey, Michael Walsh

    There has been considerable debate regarding the question of whether linguistic knowledge and world knowledge are separable and used differently during processing or not (Hagoort, Hald, Bastiaansen, & Petersson, 2004; Matsuki et al., 2011; Paczynski & Kuperberg, 2012; Warren & McConnell, 2007; Warren, McConnell, & Rayner, 2008). Previous investigations into this question have provided mixed evidence as to whether violations of selectional restrictions are detected earlier than violations of world knowledge. We report a visual-world eye-tracking study comparing the timing of facilitation contributed by selectional restrictions versus world knowledge. College-aged adults (n=36) viewed photographs of natural scenes while listening to sentences. Participants anticipated upcoming direct objects similarly regardless of whether facilitation was provided by only world knowledge or a combination of selectional restrictions and world knowledge. These results suggest that selectional restrictions are not available earlier in comprehension than world knowledge.

  17. Are New World leishmaniases becoming anthroponoses?

    Science.gov (United States)

    Rotureau, Brice

    2006-01-01

    In the New World, leishmaniases are originally wild exoanthropic zoonoses developing in sylvatic ecotopes. For a long time, Leishmania parasites have shown a remarkable plasticity to face modifications in their environment. Now, both geographical extension and numerical increase of leishmaniasis cases in the New World are giving cause for concern. These circumstances might have been provoked by the simple invasion of zoonotic foci by humans. However, dramatic evolutionary mechanisms are also at work in the New World: (i) the reduction of biodiversity associated with anthropogenic environmental changes (deforestation and urbanization); and (ii) the subsequent adaptations and interactions of new vectors and reservoir hosts at the interface with humans. This paper considers that these processes could result in new pathogenic complexes tending to synanthropic zoonoses, if not anthroponoses. Increasing man-made risk factors could thus possibly make leishmaniases a growing public health concern in the New World.
