    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. Se exponen los procedimientos seguidos para la revisión, imputación y corrección de los datos. Finalmente, se reflexiona a manera de hipótesis acerca de las posibilidades de aplicación de los Dispositivos Móviles de Captura (DMC o Personal Digital Assistant (PDA, con miras a lograr la optimización de la producción de datos sociodemográficos.

    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 Resumen: En este trabajo se desarrollaron algoritmos computacionales los cuales permiten segmentar y detectar los automóviles que se encuentran dentro de una nube de puntos 3D pertenecientes a un entorno urbano. Las nubes son adquiridas con el sistema LIDAR velodyne HDL-64E, el cual es capaz de reconstruir objetos que se encuentran a una distancia de 3 a 120 metros. El desarrollo del trabajo está dividido en dos etapas: la segmentación de objetos 3D y la indexación. Se considera que el ambiente es semi estructurado debido a que objetos como las fachadas de los edificios y el suelo pueden ser modelados por planos. La segmentación está compuesta por tres módulos: el primero consiste en la extracción del plano principal o suelo; en el segundo módulo se extraen los planos perpendiculares al suelo, los cuales son segmentados por una adaptación al método de Hough; y en el último módulo se aplica una segmentación a los objetos restantes usando el método MeanShift. La indexación está dividida en dos módulos: en el primero, los objetos segmentados son modelados por histogramas usando las direcciones de las normales de los puntos 3D de los objetos; en el segundo módulo, los histogramas son usados para comparar con una biblioteca de datos previamente construida. En este trabajo hemos usado el análisis ROC para optimizar los umbrales empleados. Se utilizan dos bases de datos: la primera es de entrenamiento y está compuesta por 4500 objetos; mientras que la segunda corresponde a la de prueba, la cual está compuesta por 3000 objetos y fue usada para verificar los resultados de entrenamiento. La aportación de este trabajo es presentar un nuevo sistema para detectar automóviles utilizando puntos 3D. Abstract: Detection of vehicles on 3D point clouds is performed by using the algorithm presented in this work. Point clouds correspond to urban environments and were acquired with the LIDAR Velodyne HDL-64E. The environment is considered semi

    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 La convergencia entre los dispositivos móviles y los servicios de la red Internet, aunque prevista, teorizada y resuelta técnicamente desde finales del siglo pasado, se ha venido retrasando por diversas causas hasta, bruscamente, acelerarse y consolidarse irremediablemente a partir de finales del año 2007. Aspectos comerciales, con la entrada de nuevos actores y estrategias al mundo de la comunicación telefónica; de uso y necesidad social, como la comunicación audiovisual personalizada; o de la utilización popular de nuevas aplicaciones red, como la localización geográfica, por ejemplo, coadyuvan a ello. Sin embargo, aún compartiendo muchos aspectos comunicativos y técnicos con la denominada web 2.0, los dispositivos móviles y su uso personalizado, contextual y ubicuo poseen especificidades comunicativas que apenas se empiezan a apuntar en estos nuevos usos cotidianos.

This has been a full experience in this kind of work. The making of a purposely defective road surface has been more difficult than was supposed, and the fast track, provided with all kinds of modern devices, has been studied to its minutest details. Its transversal section (a cubic parabola, with strong camber, made it impossible to use normal machinery, which is only apt for plane surfaces. A type of sliding formwork on rails, suitable for continuous concreting, was adopted. The total length of the track is 32 km. It includes a concrete base and a variable surface, which incorporates all kinds of surfaces that may be met with, in any state of repair. The construction time was 235 days.El imperativo de tener que disponer tramos de carretera de todos los tipos conocidos, trajo como consecuencia que la construcción de la pista de pruebas para los automóviles de la Adam Opel AG haya constituido una experiencia completa en esta clase de trabajos. La realización de un piso intencionadamente defectuoso ha resultado ser más difícil de lo que se creía en principio, y la pista rápida, que está dotada de toda clase de adelantos y de máxima seguridad, ha sido estudiada hasta en sus más mínimos detalles. Su sección transversal (una parábola cúbica, fuertemente inclinada, obligó a desechar la maquinaria normal, sólo apta para superficies planas, y a adoptar un tipo de encofrado deslizante, especial para hormigonado continuo, que se movía sobre carriles. El trazado total es de 32,2 km, con un lecho de hormigón, y un pavimento variable que abarca todos los que se pueden presentar en carreteras de distintas categorías y en cualquier estado de conservación.

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.

    Full Text Available Resumen: En este trabajo se presenta un control de seguimiento de trayectorias de robots móviles. La estructura de control propuesta combina una linealización por realimentación basada en el modelo cinemático nominal, y una red neuronal directa para el control dinámico adaptable. La dinámica del robot es aprendida por una red neuronal basada en funciones de base radial (RN-FBR en un lazo de realimentación adaptable, ajustando el peso y las funciones de base radial. Se muestra un análisis de estabilidad del sistema de neuro-control adaptable. Se comprueba que los errores de control están limitados en función del error de aproximación de la RN-FBR. El funcionamiento del controlador también se verifica experimentalmente. Palabras clave: robot móvil, control no lineal, redes neuronales, control adaptable, funciones de base radial

    Full Text Available Resumen: Este trabajo presenta un enfoque basado en la teoría del álgebra lineal, los métodos numéricos y una modificación al método de fuerza ficticia, para la navegación de robots móviles en entornos dinámicos. Para el diseño del controlador se utiliza el modelo dinámico de un robot móvil no holonómico tipo uniciclo. Trabajos anteriores a menudo ignoran la dinámica del robot, por lo que sufren de singularidades en sus algoritmos. Los resultados de simulación y experimentación confirman la factibilidad y efectividad del controlador propuesto, logrando que el robot sea capaz de adaptar su comportamiento al nivel del conocimiento disponible y navegar de manera segura en entornos no estructurados, mientras se minimiza el error de seguimiento.

    2014-07-01

    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.

    Full Text Available Resumen: Uno de los campos de aplicación más significativos de la robótica móvil consiste en robots capaces de operar en condiciones exteriores sobre terrenos no preparados (robots planetarios, robots en agricultura, robot en operaciones de búsqueda y rescate, robots militares, etc.. 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. Finalmente se expresan las conclusiones del trabajo en base a la experiencia de los autores en este campo.

    Full Text Available En los últimos años, los regímenes actuales de movilidad urbana cotidiana y sus efectos sociales y medioambientales han sido materia de debate y preocupación pública. En el presente artículo pretendemos explorar el tema a través de un caso de estudio específico: el análisis de los motivos y percepciones detrás de la adquisición y el uso de automóviles por parte de habitantes de bajos ingresos de la ciudad de Santiago, Chile. En primer lugar veremos cómo puede ser entendido el automóvil y el tipo de movilidad urbana que genera desde una óptica de teoría social y urbana. En segundo lugar, presentaremos algunas tendencias generales de uso de automóviles en Santiago. Luego se analizarán en detalle los principales argumentos detrás de la adquisición, uso y valoración del automóvil por parte de un grupo de usuarios de bajos ingresos de la ciudad. Finalmente entregaremos, a partir de los análisis presentados, algunas ideas que pueden contribuir al diseño de políticas públicas que incentiven formas de movilidad urbana sustentables en la ciudad.In recent years, existingforms of daily urban mobility and their social and environmental impacts have become issues of debate and public concern. In this article we explore this issue through a specific case study: the analysis of the motives and perceptions that lie behind the acquisition and use of cars by low income residents in Santiago de Chile. Firstly we analyze how the car and the type of urban mobility that is generated are understood in terms of social and urban theory. Secondly, we present some general tendencies of car use in Santiago. Next we look in detail at the principal arguments behind acquisition, use and valuing of the vehicle by a group of low income users in the city. Finally, we offer, based on the analysis, some ideas that can contribute to the design of public policies that incentivize forms of sustainable urban mobility in the city.

    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.

    Three major concerns face mankind's future: the impending energy crisis as caused by the depletion of the world's fossil fuel reserves, world atmospheric pollution as caused by the burning of these fuels, and mankind's destruction if the vast energy contained in nuclear weapons stockpiles is released in a global conflict. This paper describes an ambitious, combined solution to these problems by the use of deep underground detonations of thermonuclear devices/bombs to provide a virtually pollution free, world energy source into the far distant future, while achieving a significant increase in mutual trust between the superpowers and all nations. The key is believed to be thermonuclear geothermal stimulation to produce the electrical power needed for a hydrogen economy

    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.

    Se evalúa el impacto contaminante de cadmio, cromo, cobre, níquel, plomo y cinc en suelos y vegetación del entorno de un depósito de chatarra de automóviles, a diferentes distancias del mismo, tomando como referencia muestras control no contaminadas. Los contenidos totales de dichos elementos en muestras de suelos y plantas se determinan mediante ICP-AES, y su presencia en suelos mediante análisis de partículas por SEM-EDXRA. En los suelos, se detectan contenidos muy superiores a los de una muestra control para todos los elementos, que decrecen de forma gradual desde el foco contaminante. Estos contenidos en las plantas también son muy superiores a los valores de la muestra control, siendo especialmente elevados en las partes aéreas. Esta alta contaminación de las partes

Here we will consider how postulating alternative quantum worlds in the context of Hugh Everett III’s pure wave mechanics may serve to explain determinate measurement records and the standard quantum statistics. We will focus on the properties of such worlds, then briefly consider other metaphysical options available for interpreting pure wave mechanics. These reflections will serve to illustrate both the nature and the limits of naturalized metaphysics.

    The disparity between the consumption patterns of industrialized and Third World countries reflects an increase in the numbers of people living in poverty who have yet to achieve basic needs. Third World planning, encouraged by transnational companies, too often model their development goals on importing artificial life styles. This exploits poor nations by creating unrealistic demands as well as by creating a market for products that are unacceptable elsewhere. The health and environmental effects of these practices prompted the formation of consumers' association of Penang (CAP), which is trying to make people aware of the need to give basic needs the highest priority. The CAP handles complaints, tests products, and studies the socio-economic-environmental implications of development as well as conducting a far-ranging educational program. Its procedures can be adapted by any country to examine consumer awareness and to press for social reform. (DCK)

    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.

    Full Text Available The article presents a comparative analysis of knowledge about the world of nothingness. J. Boehme pointed to the fact that the world of Nothing is everlasting emptiness, where and wherein the material world could emerge. But the thing is that the world of absolute emptiness did not vanish at the moment of beginning of the world, quite the reverse, it has somehow been permanently enlarging. What will happen next is still a question. Perhaps our world will begin to be moving back on a new spiral of development, perhaps a real transition to the world of nothing will have appeared in this subtle place. For the present it is clear that these two worlds have not touched each other in mutually beneficial communication so far, and everything from our world passes into the world of nothing, and in general, the world of nothing ontologically appears to be much more existential than the world of apparent reality. What can give us some kind of key point at least, be some kind of organon in interaction with these two worlds - with the world of Nothing in which there is no matter and which cannot be perceived by any senses, and with the world of matter in which all senses are unstable and changeable? In our opinion, the only beacon and the instrument of knowledge can be the mind. To understand this phenomenon, by benefiting from a comparative methodology, this study investigates opinions of a number of philosophers, J. Boehme, G.V.F. Hegel, M. Heidegger, and J.P. Sartre, on the existence of the world of nothing.

    The visual quality of game worlds increased massively in the last three decades. However, the closer game worlds depict reality, the more noticeable it is for gamers when objects do not behave accordingly. An important problem is that the data of a game world is often scattered across different

    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.

    2002-01-01

    We investigate brane-worlds with a pure magnetic field and a perfect fluid. We extend earlier work to brane-worlds and find new properties of the Bianchi type I brane-world. We find new asymptotic behaviours on approach to singularity and classify the critical points of the dynamical phase space. It is known that the Einstein equations for the magnetic Bianchi type I models are in general oscillatory and are believed to be chaotic, but in the brane-world model this chaotic behaviour does not seem to be possible

    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.

  11. Why the world is a quantum world

    International Nuclear Information System (INIS)

    Lande, A.

    1976-01-01

    According to Einstein (1934) the supreme task of the theoretical physicist is to search for those most general and elementary laws from which the world picture can be obtained by pure deduction. However, there is no logical way leading to the elementary laws but only intuition and sound appraisal of general experience. Einstein here takes sides in the perennial dispute about induction or deduction as the principal method of science. In this paper the author illustrates the I-could-have-told-you-so story of deduction in two examples. The one describes a simple game of chance; it is quite trivial but, just because of its simplicity, exposes essential points in the raw and thereby offers an important lesson about the ultimate untenability of the doctrine of determinism. The other example deals with the sophisticated game of chance known as quantum mechanics. (Auth.)

    Full Text Available Proponemos un acercamiento, analítico y comparativo, al movimiento desde una serie de obras organizadas como pictogramas visuales que argumentan la sintaxis de la representación desde el empleo de la imagen fotográfica, el dibujo y la palabra. 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.

    International Nuclear Information System (INIS)

    Connolly, T.J.; Hansen, U.; Jaek, W.; Beckurts, K.H.

    1979-01-01

    In examing the world nuclear energy paths, the following assumptions were adopted: the world economy will grow somewhat more slowly than in the past, leading to reductions in electricity demand growth rates; national and international political impediments to the deployment of nuclear power will gradually disappear over the next few years; further development of nuclear power will proceed steadily, without serious interruption but with realistic lead times for the introduction of advanced technologies. Given these assumptions, this paper attempts a study of possible world nuclear energy developments, disaggregated on a regional and national basis. The scenario technique was used and a few alternative fuel-cycle scenarios were developed. Each is an internally consistent model of technically and economically feasible paths to the further development of nuclear power in an aggregate of individual countries and regions of the world. The main purpose of this modeling exercise was to gain some insight into the probable international locations of reactors and other nuclear facilities, the future requirements for uranium and for fuel-cycle services, and the problems of spent-fuel storage and waste management. The study also presents an assessment of the role that nuclear power might actually play in meeting future world energy demand

  15. 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.

    Full Text Available It is common ground amongst almost all commentators that the world has changed radically over the past 25 years – the 25 years since the fall of the Berlin Wall heralded the ending of the Cold War, the reunification of a tragically divided Europe, and the acceleration of the process of globalisation which has its only comparable period in the decades leading up to the First World War in 1914. When analyzing the Emerging World Order it is important to cover more than Brazil economy or any other individual BRICs or other Emerging Powers. Instead, our analysis will provide a global view about the economic and political global power structures which are evolving and forming before our eyes, and then to talk about the challenges these emerging realities pose for us in Europe, and in the West in general.

  17. Surfing the quantum world

    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 oil and gas resources of the Middle East and North Africa (MENA) will be critical to meeting the world's growing appetite for energy. The greater part of the world's remaining reserves lie in that region. They are relatively under-exploited and are sufficient to meet rising global demand for the next quarter century and beyond. The export revenues they would generate would help sustain the region's economic development. But there is considerable uncertainty about the pace at which investment in the region's upstream industry will occur, how quickly production capacity will expand and, given rising domestic energy needs, how much of the expected increase in supply will be available for export. The implications for both MENA producers and consuming countries are profound. The World Energy Outlook, published by the International Energy Agency (IEA), seeks to shed light on these very complex issues

  2. The world food problem

    Energy Technology Data Exchange (ETDEWEB)

    Olson, R A

    1974-07-01

    Argument continues in the world press as to the urgency of the food problem. Some economists in equating world food production statistics with population figures have convinced themselves there is more than enough food per capita and, accordingly, no problem. Looking in greater depth than these gross averages, however, we find that there is indeed a prospective problem, and of such a nature and magnitude as to tax all of mankind's talents and resources in its resolution. It is true that certain of the developed countries of the world in the last generation acquired agricultural production capabilities that notably exceeded the resident population's capacity to consume. 'Surplus' in these areas became an ugly word during this period of a generally favorable weather cycle, and restrictions on the amount of and that could be devoted to graincrops were imposed to curb this tremendous capacity. A fickle Mother Nature, however, has turned things around during the early 1970's by one or another of her many vacillations in the form of local drought, excess moisture, shortened growing season, or other means, in some of the major producing areas. Inconsequence, the food grain surpluses are now gone and the world is looking at a three to four week reserve at any given moment. The cost of food products available from exporting countries has doubled and trebled in price during the past two years. The potential for famine exceeds in magnitude anything the world has ever known. It is against this background that the World Food Conference will be held in Rome during November of this year.

    2003-08-01

    On January 1, 1995, representatives from 76 countries signed the World Trade Organization charter, which for years had been part of a temporary trade agreement. The WTO's emergence as a fully empowered supranational body seemed to reflect the triumph of what the first President Bush had described as the "new world order." That order was based on two assumptions: that a healthy economy and a sound financial system make for political stability, and that countries in business together do not fight each other. The number one priority of U.S. foreign policy was thus to encourage the former Communist countries of Europe and the developing nations in Latin America, Asia, and Africa to adopt business-friendly policies. Private capital would flow from the developed world into these countries, creating economic growth. It sounded too good to be true, and so it proved. The new world order of Bush père and his successor, Bill Clinton, has been replaced by the new world disorder of Bush fils. Under the second Bush's administration, the economic and political rationale-behind the Washington consensus of the 1990s has unraveled, forcing a radical change in our perceptions of which countries are safe for business. Negotiating this new environment will require companies to more rigorously evaluate political events and more carefully assess the links between political, economic, and financial risk factors. They'll need to be more selective about which markets to enter, and they'll need to think differently about how to position themselves in those markets. The geopolitical events of the past year, the Bush administration's global war on terror, as well as ongoing convulsions in traditional political and economic relationships must be understood and managed by corporate leaders worldwide. With careful analysis, business leaders can increase their companies' visibility and better respond to the uncertainties of the new world disorder.

    Sandia National Laboratories has designed and developed systems capable of large-scale, three-dimensional mapping of unstructured environments in near real time. This mapping technique is called rapid world modeling and has proven invaluable when used by prototype systems consisting of sensory detection devices mounted on mobile platforms. These systems can be deployed into previously unmapped environments and transmit real-time 3-D visual images to operators located remotely. This paper covers a brief history of the rapid world modeling system, its implementation on mobile platforms, and the current state of the technology. Applications to the nuclear power industry are discussed. (author)

Regular wars and irregular wars will continue and probably about different subjects than we are used to. The article proposes...... that the form of war will be more about temporalities, i.e. fast interchanges or, rather, more risky protracted wars of attrition and exhaustion and less about tactical well defined territories. The West can neither dominate such wars nor establish one world that is ruled or even governed. The risk is that we...

    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.

    1981-01-01

    Papers presented to the 11 World power conference ''Power for our peace'' held in Munich in September, 1980 are shortly surveyed. A few papers were devoted to nuclear power, that represents its present- state-of-the-art in the world. Except for the paper presented by experts of the International Energy Agency (IEA) and a number of others, there is carefulness and realism with respect to nuclear power in the most part of the papers; its forecasted growth rates are rather moderate. Even in the IEA paper the total world nuclear installed capacity in 1985 is evaluated about 550 GW, that is substantially smaller earlier evaluations. It is acknowledged that the primary energy production almost in all countries will increase mainly due to nuclear power and coal. But there are no answers to the problems related to management of the nuclear power development and to the public opinion in many countries. It is underlined that the problems of world power supply can be solved only on an international basis [ru

    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.

  16. Wind around the world

    1998-01-01

    A combination of cost reductions and progressive policies in key markets kept the world wind market percolating in 1997 with a record 1510 MW of new wind capacity installed, representing annual sales of more than $1.5 billion. This new record surpasses last year''s total by 24 percent, about the average annual rate of growth for the last three years. Worldwide utility-scale wind installations at the end of 1997 totaled 7763 MW. Most activity occurred in Europe, which accounted for over 75 percent of 1997 installations. Germany was again the world''s leading single market, this time by quite a large margin, accounting for more than one-third of the annual total by itself at 532 MW in 1997. The end of 1997 also marked the time at which Germany officially passed the US as the largest total single market with over 2079 MW in total installations versus about 1805 MW for the US, although the US had actually lost the lead by mid-year. Spain is the new addition to the top echelon of world wind markets, installing 215 MW in 1997 that more than doubles their total installed capacity over the previous year and ranks them number three in the world for the year. Denmark''s 1997 total of 300 MW is also a record, although this estimate could go up as the official count is finalized. India, the second largest wind market in 1995 and 1996, slipped several notches because of a variety of factors, including a change in government and a slowdown in the economy. The US wind market continues to stagnate as it has for the last several years, largely because of the uncertainty surrounding restructuring of US electric utilities. The US market is poised for a big comeback in 1998, however

    Since the beginning of the 21. century, a war has started between the USA, China and India. The USA, first oil consuming and importing country in the world, has now to take into account the increasing energy consumption of China and India. China is now, just behind Japan, the third oil importing country and India ranked number seven. From the Gulf of Guinea to the Arabic peninsula, from the Orenoque basin to the Caspian sea banks, Washington, Beijing and New Delhi covet the same oil fields. This rivalry exacerbates the political tensions in many regions of the Earth and already provokes a latent food crisis. This black gold war is changing the World's face and should provoke serious armed conflicts. (J.S.)

    This article explores the political differences between academic activism and the recently emerged research impact agenda. While both claim that academic work can and should engage with and influence the world beyond the academic ‘ivory tower’, their political meaning and practice are radically...... different. Following the distinction made by Jacques Rancière, we argue that research impact performs a policing function which, despite its own rhetoric, is arranged as an attempt to ensure that academic work maintains a neoliberal status quo by actually having no real political impact. Academic activism......, in contrast, serves to politicize scholarly work by democratically disrupting political consensus in the name of equality. Being an academic activist in an era of research impact rests in a twofold movement: that of both acting in the name of equality in an effort (using Marx’s terms) to ‘change the world...

    Web algorithms like Facebook’s so-called Edgerank algorithm play an increasingly important role in everyday life. The recent surge of research in such algorithms often emphasizes algorithmic orderings as powerful but opaque. In this essay, we propose an alternative reading of the Edgerank algorithm...... marketing blogs about how to handle the algorithm in practice. Based on these events, we construct an ‘internalistic’ account of the rhetoric of Edgerank, opening for an exploration of its moral grammar and the world or dwelling place it assumes and enacts. We find that the world of Edgerank is ordered....... In the rhetoric that comes with Edgerank, this tension is not something to be overcome, but rather a self-justifying hybrid, which points to a potential displacement of moral grammars in an age of computational valuation....

    The 21st World Energy Congress offers a unique opportunity for all stake-holders of the energy sector to meet and exchange visions, strategies and practices, during four days of very intensive and interesting sessions, round-tables and exhibitions. More than 3,000 energy leaders gather from around the world from both developed and developing countries, from all types of energy, from public and private companies and government organisations, in order to think together about how to bring about a sustainable and acceptable energy future. The truth is that nobody has the choice any longer. All energy leaders have to take decisions every day, and they need to have a clear analysis of what is at stake, what the risks are, and what the solutions can be.

    World spinors are objects that transform w.r.t. double covering group Diff(4, R) of the Group of General Coordinate Transformations. The basic mathematical results and the corresponding physical interpretation concerning these, infinite-dimensional, spinorial representations are reviewed. The role of groups Diff(4, R), GA(4, R), GL(4, R), SL(4, R), SO(3,1) and the corresponding covering groups is pointed out. New results on the infinite dimensionality of spinorial representations, explicit construction of the SL(4, R) representations in the basis of finite-dimensional non-unitary SL(2, C) representations, SL(4, R) representation regrouping of tonsorial and spinorial fields of an arbitrary spin Lagrangian field theory, as well as its SL(5, R) generalization in the case of infinite-component world spinor and tensor field theories are presented.

    As energy consumption increased by a factor 20 during the 20. century, energy has not only an economic, but also a political role, and its management involves diplomatic, social, and now environmental issues. The author discusses the primary role still hold by fossil energies (coal, gas and oil) in the world energy consumption, comments the energy reserve assessments, outlines the financial needs for a renewable energy development, and questions the future evolution of reserves and consumption, as well as the consequences of climate change or the uncertainty about economic growth. The world energy assessment shows important differences between inhabitants: a US citizen consumes more than eight times more than a Chinese one. The shares of the different energy sources are also different from one country to another. In order to decrease the demand in energy, energy efficiency must be improved and user behaviour must evolve

  20. World status - nuclear power

    International Nuclear Information System (INIS)

    Holmes, A.

    1984-01-01

    The problems of nuclear power are not so much anti-nuclear public opinion, but more the decrease of electricity consumption growth rate and the high cost of building reactors. Because of these factors, forecasts of world nuclear capacity have had to be reduced considerably over the last three years. The performance of reactors is considered. The CANDU reactor remains the world's best performer and overall tends to out-perform larger reactors. The nuclear plant due to come on line in 1984 are listed by country; this shows that nuclear capacity will increase substantially over a short period. At a time of stagnant demand this will make nuclear energy an important factor in the world energy balance. Nuclear power stations in operation and under construction in 1983 are listed and major developments in commercial nuclear power in 1983 are taken country by country. In most, the report is the same; national reactor ordering cut back because the expected increase in energy demand has not happened. Also the cost-benefit of nuclear over other forms of energy is no longer as favourable. The export opportunities have also declined as many of the less developed countries are unable to afford reactors. (U.K.)

  1. The world market

    International Nuclear Information System (INIS)

    Field, D.

    1991-01-01

    This paper reports on the Lambda Power Supply Group, with headquarters in Melville, Long Island owned by UNITECH PLC, based in Reading in the United Kingdom. The Group forms the greatest Power Supply manufacturing and marketing organization in the world, with sales for 1989/90 in excess of $300 million. World markets have distinct trends which need to be recognized in the years ahead. In general, these trends are now commercially driven and center around: The globalization of world markets and the need to service the same customer in the Far East, North America and Europe. The drive to reduce physical size, improve performance and quality and the need to reduce costs. This requires significant investment in research and development to maintain technological leadership. The increasing speed of new product introductions requires power supply companies to work hand-in-hand with their customers as a partner, or even as an extension of the OEM's own development department. A significant trend within Europe is the perception by Far Eastern equipment manufacturers that, by 1992, trade barriers will be erected, and these large manufacturers are increasingly establishing factories within Europe, where they will need local content in their products. Whilst addressing a Global Market with products which are suitable for worldwide sale, it is important to note that local presence is vital, not only to service the customer, but also to monitor the customers needs which have significant differences in certain markets

    The 2008 report provides invaluable analysis to help policy makers around the world assess and address the challenges posed by worsening oil supply prospects, higher energy prices and rising emissions of greenhouse gases. 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 will be

A three day 'conference in the conference' covering all aspects of pellets: raw material potentials, innovative pellets production systems, torrefaction, new combustion technologies, trade and market development, health and safety aspects, etc. B) Market outlook: Policy and targets for renewable energy to find an alternative to fossil energy are being put in place, increasing the demand for sustainable modern bioenergy. 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

    CEDIGAZ proposes this new survey about LNG in view of the main changes which have occurred on this market during the past few years. Several projects under construction or planned three years ago are now commissioned (Qatargas) or on the verge of starting to export this year (Trinidad LNG, RasGas, Nigeria LNG) or next years (Oman LNG). The Asian crisis, which had major impacts on both short-term demand in Asia and LNG prices, has brought about new uncertainties to the long-term prospects. At the same time, it now seems more and more certain that firstly India and then China will import LNG in the next decade. It remains to be seen at what level and when this will occur. LNG growth in Europe has now become a reality, and new potential markets, for example in South America (Brazil), are also being considered as real opportunities in the near future. Considering these 'new' trends, an updated study about LNG appeared necessary. This survey 'World LNG Outlook - 99 Edition' is organised as the previous one: a historical record since 1964 (Chapter 1) followed by a description of the infrastructures existing in 1998 (Chapter 2). The analysis continues with world trade prospects by the year 2010 (Chapters 3 to 5). Chapter 6 describes the future LNG chain and the last Chapter (7) focuses on economic matters (LNG price trends, cost reductions). The study 'World LNG Outlook - 99 Edition' offers hence a comprehensive panorama of this sector from a short and long-term point of view. (author)

    The world's population growth rate peaked at slightly over 2%/year in the late 1960s and in 1986 is down to 1.7% and falling. Annual numbers added continue to rise because these rates apply to a very large base, 4.9 billion in 1986. According to UN medium variant projections, world population growth will peak at 89 million/year in the late 1990s and then taper off until world population stabilizes in the late decade of the 21st century at about 10.2 billion. Close to 95% of this growth is occurring in less developed countries (LDCs) of Africa, Asia (minus Japan), and Latin America. LDC fertility rates are declining, except in sub-Saharan Africa and parts of Latin America and South Asia, but most have far to go to reach the replacement level of 2.1 births/woman. Fertility is below replacement in virtually all more developed countries. For LDCs, large numbers will be added before stabilization even after attainment of replacement level fertility because of the demographic momentum built into their large and young population bases. This complicates efforts to bridge gaps between living standards in LDCs and industrialized countries. From a new debate about whether rapid population growth deters or stimulates economic growth, a more integrated view has emerged. This view recognizes the complementary relationship between efforts to slow population growth and other development efforts; e.g., to improve health and education, upgrade women's status, increase productivity. Most effective in the increased contraceptive prevalence and fertility declines seen in many LDCs has been the combination of organized programs to increase access to family planning information and supplies with socioeconomic development that enhances the desire for smaller families.

    What will the credit crunch and economic recession mean for energy markets? Will investment cutbacks lead us towards a supply crunch a few years down the line? How could the transition to a clean global energy system be financed? These are just three of the questions that World Energy Outlook 2009 addresses. Incorporating recent developments in energy and environmental policy, this year's Outlook draws on the latest data reflecting the impact of the global financial and economic crisis and takes into account ongoing gyrations in energy prices. The resulting analysis presents a full update of energy projections through to 2030, fuel by fuel, and with more country-level detail than ever before. WEO-2009 puts the spotlight on three special topics: (1) Financing energy investment under a post-2012 climate framework: What policy action is needed to increase deployment of new energy technologies? Where are the most cost-effective opportunities for carbon mitigation? This ground-breaking analysis, which zooms in on the crucial period through to 2020, provides a robust quantitative basis for United Nations Framework Convention on Climate Change negotiations in the lead-up to the crucial climate meeting in Copenhagen in December 2009. (2) Prospects for global natural gas markets: How hard will the credit crisis and economic recession hit gas demand and investment in gas supply? How will geology and geopolitics affect future gas supplies? Through field-by-field analysis of production trends of the world's key gas fields and a bottom-up analysis of upstream costs and investment, WEO-2009 takes a hard look at future global gas supply. (3) Energy trends in Southeast Asia: In recognition of the growing influence Southeast Asia is having on global energy markets, WEO-2009 includes an in-depth analysis of this fast-growing region. The annual WEO report -- the flagship publication of the IEA -- is widely recognised as the most authoritative source of global energy

    Full Text Available Scholars employing world-system theory have tended to examine how world-systemsdevelop and expand, while few have addressed the fragmentation or collapse of world-systems. This paper explores the conditions of world-system collapse using Habermas's concept of legitimation crisis as a starting point. The paper posits that legitimation crises are a recurring problem in world-systems and have led to collapse in a number of cases. Prehistoric North American and Pacific world-systems are used as examples.

    1992-01-01

    As an introduction to this special issue 'Worlds of difference: Scenarios's for the economy, energy and the environment 1990-2015', an outline is given of the future of the world and the Netherlands, based on four scenarios. These scenarios are published in 'Scanning the future' in May 1992 by the CPB, the Dutch Central Planning Bureau. The Global Shift (GS) scenario is characterized by a very dynamic technological development, the free market perspective, strong economic growth in the Asian economies, and a relative economic regression in Western Europe. In the European Renaissance (ER) scenario the technological development is less dynamic and more gradual than in the GS scenario. The Balanced Growth (BG) scenario is dominated by a sustainable economic development and a strong technological dynamic development. The Global Crisis (GC) scenario shows a downward spiral in many areas, stagnating developments and fragile economies as results of the trends in the eighties. The first three scenarios are elaborated for the Netherlands. Also attention is paid to the aims and meaning of long-term scenarios. 2 figs., 2 tabs., 3 refs

  20. World wide spatial capital.

    Sen, Rijurekha; Quercia, Daniele

    2018-01-01

    In its most basic form, the spatial capital of a neighborhood entails that most aspects of daily life are located close at hand. Urban planning researchers have widely recognized its importance, not least because it can be transformed in other forms of capital such as economical capital (e.g., house prices, retail sales) and social capital (e.g., neighborhood cohesion). Researchers have already studied spatial capital from official city data. Their work led to important planning decisions, yet it also relied on data that is costly to create and update, and produced metrics that are difficult to compare across cities. By contrast, we propose to measure spatial capital in cheap and standardized ways around the world. Hence the name of our project "World Wide Spatial Capital". Our measures are cheap as they rely on the most basic information about a city that is currently available on the Web (i.e., which amenities are available and where). They are also standardized because they can be applied in any city in the five continents (as opposed to previous metrics that were mainly applied in USA and UK). We show that, upon these metrics, one could produce insights at the core of the urban planning discipline: which areas would benefit the most from urban interventions; how to inform planning depending on whether a city's activity is mono- or poly-centric; how different cities fare against each other; and how spatial capital correlates with other urban characteristics such as mobility patterns and road network structure.

  1. World oil market simulation

    International Nuclear Information System (INIS)

    Baldwin, N.

    1992-01-01

    This paper presents a recursive simulation model of the world oil market - the World Oil Market Simulation Model (WOMS). The objective was to construct a computationally simple model which provides a transparent view of the workings of the oil market. In the event WOMS has a number of features which distinguish it from other published models: the effect of exchange rate movements is incorporated in the supply and demand functions; both demand and supply functions are dynamic; the non-OPEC supply functions account for the geological as well as the economic aspects of supply; oil prices can be determined either by OPEC setting prices (as normally included in this type of model) or by OPEC setting volumes and market forces determining the price; and consistency checks on consumers' and producers' behaviour are incorporated to confirm the plausibility of model projections. The paper commences with an outline of the model structure followed by an examination of the choice of the appropriate data. The main sections of the paper discuss the estimation of the demand and non-OPEC supply functions. Finally the modelling of OPEC's behaviour is addressed. Comparisons are made throughout with other published work. As the model was estimated using data covering 1960 to 1985, brief comments are also made comparing the events of 1986 with model determined values. (author)

    2010-01-01

    This article discussed conditions in world coking coal markets. There is increased demand from Asia for metallurgical coal imports. World iron production was up 22 percent in first 7 months of 2010. Supply is up in Australia, the United States, Canada, New Zealand, Russia, and Mongolia, but the unexpected surge in supply caused prices to drop following a robust start to the year. Coking coal exports are up for the United States and Australia, but a delay in expanded production is expected until 2014. There is increased demand from Brazil, India, Taiwan, South Korea, and Japan as well as new plants in Thailand, Indonesia, and Brazil. Unexpectedly, Australia is backing out of the Chinese market but increasing exports to Japan and South Korea. India is seeing flat performance in iron production and imports, and the United States has surged back into Asia. A considerable increase is expected in the seaborne import requirement by 2020. Prices are expected to fall and then rise. This presentation also discussed whether coking coal index pricing is impossible or inevitable. 3 tabs., 5 figs.

    A World's Waste·An Exhibition that challenges a number of preconceptions about the nuclear industry and the environment while at the same time pushing back the limits of conventional uses of photography and the visual arts. Drawing on a variety of disciplines and utilising means of visual presentation beyond the scope of many exhibitions, this in-depth look at the impact of Sellafield and the nuclear industry on life in Cumbria and beyond attempts through a variety of media from painting through photography to video, performance and installation work, to picture the invisible: radiation and its consequences for the world. Through varied approaches the work selected for exhibition adds a number of voices to a discussion divided between knowledge based on over complex information pitted against opinion reacting from emotion. The catalogue to the exhibition adds a series of articles which go with the art work. The anti-nuclear articles are balanced by BNFLs contributions which put forward the pro-nuclear viewpoint.

    2013-01-01

    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 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

    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

    A generic prediction of inflation is that the thermalized region we inhabit is spatially infinite. Thus, it contains an infinite number of regions of the same size as our observable universe, which we shall denote as O regions. We argue that the number of possible histories which may take place inside of an O region, from the time of recombination up to the present time, is finite. Hence, there are an infinite number of O regions with identical histories up to the present, but which need not be identical in the future. Moreover, all histories which are not forbidden by conservation laws will occur in a finite fraction of all O regions. The ensemble of O regions is reminiscent of the ensemble of universes in the many-world picture of quantum mechanics. An important difference, however, is that other O regions are unquestionably real

    Coal will have an increasing role in world energy in the next three decades. The coming dependence on coal as the major fuel will radically affect international cooperation, as the US, USSR, and China account for approx. 85% of the known geological resources, and coal's likely economic marginality poses questions as to which producer will be capable of a profitable export trade. Energy transportability is becoming more important, as people can no longer move near to the sources. Also discussed are the uncompetitiveness of wasteful energy expenditure; the crucial relation of energy consumption to a country's gross national product; the energy intensities of selected industries; the necessity of elasticity in responding to changing energy supplies; the need for increased energy consumption in building up the developing countries; and good control, made achievable via advances in solid-state electronics, as the deciding factor in proper energy management.

    'Coal to liquid' (CTL) is a well known technic used since years especially by the Germans during the last world war and South Africa during the oil embargo. The combination of coal gasification and Fischer-Tropsch synthesis allows the production of synthetic diesel and gasoline. Nice alternative for those countries with large reserves of coal (China, South Africa, USA) which want to be more 'oil-free' in the long term, it faces however quite a lot of challenges: Very sophisticated technic, not yet proven for large scale of unit, high investment costs, necessity to add up CO 2 capture and storage (CCS) due to climate change constraints... In any cases this process seems more adequate and competitive to produce electricity and power than to focus on transportation fuels which are more easily manufactured from oil. (author)

    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.

  10. World wide spatial capital.

    Directory of Open Access Journals (Sweden)

    Rijurekha Sen

    Full Text Available In its most basic form, the spatial capital of a neighborhood entails that most aspects of daily life are located close at hand. Urban planning researchers have widely recognized its importance, not least because it can be transformed in other forms of capital such as economical capital (e.g., house prices, retail sales and social capital (e.g., neighborhood cohesion. Researchers have already studied spatial capital from official city data. Their work led to important planning decisions, yet it also relied on data that is costly to create and update, and produced metrics that are difficult to compare across cities. By contrast, we propose to measure spatial capital in cheap and standardized ways around the world. Hence the name of our project "World Wide Spatial Capital". Our measures are cheap as they rely on the most basic information about a city that is currently available on the Web (i.e., which amenities are available and where. They are also standardized because they can be applied in any city in the five continents (as opposed to previous metrics that were mainly applied in USA and UK. We show that, upon these metrics, one could produce insights at the core of the urban planning discipline: which areas would benefit the most from urban interventions; how to inform planning depending on whether a city's activity is mono- or poly-centric; how different cities fare against each other; and how spatial capital correlates with other urban characteristics such as mobility patterns and road network structure.

    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.

    The 21. of April 2005, was held in Paris the 6. international petroleum meeting whose main theme was: the supply and demand. The participants of this summit have in majority argued for a greater opening of the productive countries to the international investments which are indispensable to face with a world demand of oil in full expansion. Total has announced the approval by the British authorities of the development of the gas and condensates deposit of north Forvie, located at about 440 km at the nord-east of Aberdeen. Technip and Kerr-McGee Oil and Gas Corp., have received the prestigious price of the Offshore Technology Conference 2005. The Norway and the United Kingdom have signed a cooperation treaty for stimulating the development of petroleum and natural gas deposits in North sea. The petroleum groups Royal Dutch Shell and ExxonMobil think to sale their shares in three fields in the North sea. Total and Lubrifin, one of the main manufacturers and distributors of lubricants and greases on the Romanian market, have just finalize an agreement for the establishment of a common firm: Total Lubrifin. The IEA has published a study for the governments to rapidly reduce the petroleum consumption in transports in the case of crisis or breakdown of the supply. In order to avoid an accident risk which could have disastrous environmental consequences, by the important transit in the Bosphore pass, a plan (dating from 1995) provides that the petroleum of the Caspian sea transiting by the Russian harbour of Novorossiisk, on North sea, be conveyed by sea way to the Bulgarian harbour of Bourgas, to be transported by pipeline on 320 km to the Alexandroupolis harbour. Vladimir Poutine has received last April to the Kremlin John Browne, general director of the British firm BP, came ask for its investment in Russia in the common firm: TNK-BP.

  16. 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.

Areva company is investing 30 million euros in its Chalon-Saint-Marcel plant, it is the consequence of the extension of service life of nuclear power plants in the Usa. Areva holds 40% of the American market concerning the replacement of steam generators and 50% of that concerning the replacement of closure heads. The Obrigheim nuclear power plant was definitely closed down on may 2004, this decommissioning is a step forward in the German policy of progressively stepping out of nuclear energy. Chinese authorities are willing to construct 40 nuclear reactors in 15 years, despite that, the contribution of nuclear energy to the generation of electricity will reach only 4% in 2020. In 2007 Cea will begin the construction works of a new research reactor (Jules Horowitz reactor) in the Cadarache site. Prices of the yellow cake have been going up during the last years: from 9 dollar the pound in 2001 to 23 dollar today. Nuclear fuel manufacturers do not worry because far higher prices have been previously reached (70 dollars in the seventies) and uranium reserves are expected to assure 200 years of electricity generation at the same level of production as today.

After a bibliographic revision around the concepts of study, it develops an experiment with the aim of deeping in the field of creativity and the ethics within the most popular video made by four Spanish youtubers: ElRubius, Gym virtual, Dulceida y Verdeliss. Metodology consists in the analysis of each video from several parameters of the creativity, to then, through using Socratic maieutics, to formulate a battery of questions which are connected, as answers, to ethical axioms, later organized as a list in some categories. As a result, it shows the viability of this process for extracting ethical axioms susceptible to be used by users and youtubers. The most numerous axioms’ category of the study is “Social responsibility”, alludind therefore to the importance that this influencers have over their environment and, hence, to the importance of the ethics in their work.

    In a world where big differences in regional energy prices impact competitiveness, who are the potential winners and losers? Huge volumes of oil are needed to meet growing demand and offset declines in existing fields. Where will it all come from? What could trigger a rapid convergence in natural gas prices between Asia, Europe and North America, and how would it affect energy markets? Is the growth in renewable energy self-sustaining and is it sufficient to put us on track to meet global climate goals? How much progress is being made in phasing out fossil-fuel subsidies and expanding access to modern energy services to the world’s poor? The answers to these and many other questions are found in WEO-2013, which covers the prospects for all energy sources, regions and sectors to 2035. Oil is analysed in-depth: resources, production, demand, refining and international trade. Energy efficiency – a major factor in the global energy balance – is treated in much the same way as conventional fuels: Its prospects and contribution are presented in a dedicated chapter. And the report examines the outlook for Brazil's energy sector in detail and the implications for the global energy landscape.

    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.

  8. Spice and the World

    Around 1500 , the world experi ̄enced an explosion of exploration which greatly transformed the world for the next several hundreds of years. During this time, Christopher Columbus, Vasco da Gama, and other seafaring entrepreneurs sought new routes to India’s Malabar Coast and the Indonesian archipelago. The objective of their ef ̄forts was mainly spice specifically pepper, cinna ̄mon, nutmeg, clove, and a few others. In the en ̄suing years, the Spanish, Portuguese, English, and Dutch would all seek to dominate the spice trade, employing an astonishing amount of blood ̄shed and brutality to achieve their aims. They were undermined only by pirates, who would occasional ̄ly plunder the spice boats, relieving them of their precious cargo. The reason behind their desire to seek spice, was not only, and in fact, not even primarily, profits. In an age that poured its commercial ener ̄gies into such un - poetical ends such as arms, oil, and mineral ores, the drive to obtain anything quite so quaintly insignificant as spice must strike us today as mystifying indeed. While historians of ̄ten point to medieval Europe’s problems with ran ̄cid meat, along with the mind -numbing repeti ̄tiveness of its diet, as the source of spice’s early popularity, the main reason for desiring spice came down to one simple thing: mystery. Spices were, in a sense, magical if not divine, arriving by un ̄known means from the vast blank spaces on the map, spaces populated by dragons, gods, and monsters. From mystery grew mystique. It was a seductive premise. This article starts by examining the rise of Europe’s economy after the first millennium and the subsequent demand for Eastern luxuries. Ginger, mace, and other exotic ingredients quickly became status symbols among noblemen—not unlike furs or jewels—as well as staples in upper -class kitch ̄ens, with nearly every dish deluged by seasonings, to the point where the medieval appetite for spice looked less like a taste

  9. [History of world neurosurgery].

    In 5000 BC, South American tribes digged the bones in the living head to seek ways to communicate with the gods, which was primitive trephination and may be the first neurosurgical behavior. In 2600 BC, Imhotep in ancient Egypt took the brain out of the head from the nose, for a better preserve of the mummy, which was a prototype of modern transsphenoidal surgery. And the development of anatomy in ancient Greek laid a solid foundation for neurosurgery. From 500 to 1500 AD, the rise of religion and the occurrence of war, prompted a large number of craniocerebral trauma, which contributed greatly to the early development of neurosurgery as a distinct specialty. In 1861, Brocca astutely localized the language function to the third left frontal convolution in a series of studies, which was considered to be of landmark importance in the understanding of cerebral localization. In 1878, William Macewen performed a successful surgery to remove an en plaque meningioma with intrathecal anesthesia, representing the first modern neurosurgical operation. However, the contributions of the Americans, starting with Harvey Cushing, exerted a definitive force. Portuguese Moritz performed the first cerebral angiogram on a living schizophrenia patient in 1926. And he established the Moniz-Lima prefrontal leucotomy for the treatment of schizophrenia, for which he won the Nobel Prize in Physiology and Medicine in 1949. In 1968, the Swiss scholar Yassagir firstly carried out neurosurgical surgeries under the microscope. China's neurosurgery was founded by Zhao Yicheng in 1952 in Tianjin, and the gap in neurosurgery between China and the world gradually narrowed after 60 years of development.

    8 nuclear power plants are operating in Spain, they generate about 23% of the production of electricity in the country. A broad debate has been launched to clarify the future of nuclear energy in Spain. The 2 oldest plants in the world: Dungeness-A and Sizewell-A in U.K. have been decommissioned. In U.K. 23 nuclear power plants are operating and all except one will have to be closed by 2023 to let room for a new generation of reactors. Korean authorities wish to invest 23.5 milliard euros in the building of 39 power plants among which 8 will be nuclear. Swiss authorities have launched a public debate on the selection procedure of a site for the disposal in deep geological layers of radioactive wastes. Jordanian authorities wish to develop a civil nuclear program. French authorities have announced that a total of 6500 radioactive sources are used throughout the country for research or industrial purposes. Only 34% of the German people back a quick step out from nuclear energy and 60% of the Pole are not against the construction of a nuclear power plant. Finnish authorities consider a sixth reactor as a valid solution to face the strong energy demand of the country. Australian authorities consider the development of a nuclear energy program in Australia as an adequate measure to take benefit of the large uranium natural resource of the country and to face the growing demand for electricity. Australian authorities have signed an agreement with Chinese counterparts for exporting uranium. Russian authorities have passed a bill for reforming the nuclear industry in order to make it more competitive. (A.C.)

    This document gathers pieces of information concerning nuclear industry worldwide. The most relevant are the following ones. CGN (China General Nuclear) will launched in 2017 the construction of a prototype of a small transportable modular reactor whose purpose is to produce electricity on a remote place like an island or aboard a boat for long-term missions. The Wylfa reactor (490 MWe) was decommissioned on December 30., 2015. Wylfa was the last Magnox type reactor operating in the world. In France a campaign of information and iodine drug dispatching has been launched for people living near nuclear power plants. The global cost of the CIGEO project whose aim is the disposal of high-level radioactive wastes has been estimated to 25 billions euros including construction costs, operating costs over a 100 year period and dismantling costs. The European Commission has warned France that the financial provisions made for the dismantling of nuclear facilities and the processing of the consequent wastes are not sufficient to cover the future costs. 4 reactors with a power of 1400 MWe each, are being built on the Barakah site in Abu Dhabi, works are on time and the first unit may operate end 2016. Wikileaks has accused AREVA of not taking all necessary measures for the protection of its employees at the Bakouma mine. AREVA denies the charges and affirms that regulations and safety requirements are the same as for its French sites whatever the country. The initiative 'Nuclear for Climate' gathering pro-nuclear associations worldwide, intends to remind the international community that nuclear energy is an important tool to fight climate change. The French site for the disposal of low-level radioactive wastes is facing saturation in the very short term while the volume of such wastes is expected to soar in the next decades as the dismantling programmes will gain in importance. A new policy for the management of such wastes is needed. (A.C.)

    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.

EDF has inaugurated a logistic hub for the supply of spare parts for its 58 operating reactors. Russia has opened a new site to store spent fuels from RBMK reactors. This site is located at Zheleznogorsk near Krasnoiarsk in Siberia. The capacity of the La Hague fuel reprocessing plant is 1700 tonnes a year but the plant processes only between 800 and 1000 tones because most of its foreign contracts have come to an end and have not been renewed. In 2012 the plant is expected to process 1003 tonnes for EDF and 12 tonnes for The Netherlands. AREVA has delivered to the CNNC Chinese company 700 fuel assemblies and 800 control rod clusters. The French Institute for Radioprotection and Nuclear Safety (IRSN) said that there was neither health nor environmental hazards on French soil due to the Fukushima accident. The French Academy of Sciences has highlighted the least sanitary impact of nuclear power compared to other energies. The American Nuclear Safety Association has stated that the American nuclear power plants are safe and that the probability of a severe accident is very low. A new study shows an excess of cases of leukemia near nuclear power stations in France. This study rests on very few statistical cases. An opinion survey in the United Kingdom shows that the construction of nuclear power stations is considered as the best investment in infrastructures. EDF has planned to recruit in 2012 about 6000 people essentially in the nuclear sector. The Netherlands government has given its consent for the construction of the high flux reactor Pallas on the Petten site, this reactor will replace the HFR whose lifetime is over 50 years. (A.C.)

    1992-05-23

    1200 delegates from 175 member countries attended the 45th World Health Assembly in Geneva. Everyone at the Assembly ratified measures to prevent and control AIDS. 12 countries intended to do long term planning for community based care for AIDS patients. Further the Assembly denounced instances where countries and individuals denied the gravity of the AIDS pandemic. In fact, it expressed the importance for urgent and intensive action against HIV/AIDS. The assembly backed proposals to prevent and control sexually transmitted diseases that affect AIDS patients, especially hepatitis B. For example, in countries with hepatitis B prevalence 8% (many countries in Sub-Sahara Africa, Asia, the Pacific region, and South America), health officials should introduce hepatitis B vaccine into their existing immunization programs by 1995. By 1997, this vaccine should be part of all immunization programs. The Assembly was aware of the obstacles of establishing reliable cold chains for nationwide distribution, however. Delegates in Committee A objected to the fact that 50% of the populations of developing countries continued to have limited access to essential drugs. They also expressed disapproval in implementation of WHO's 1988 ethical criteria for promotion of drugs which WHO entrusted to the Council for International Organisations of Medical Sciences (CIOMS). CIOMS lacked WHO's status and thus could not effectively monitor drug advertising. In fact, the pharmaceutical industry as well as WHO provided the funds for a meeting of 25 experts to discuss principles included in the ethical criteria. At least 4 countries insisted that WHO have the ultimate authority in monitoring drug advertising. Delegates did adopt a compromise resolution on this topic which required that industry promotion methods be reported to the 1994 Assembly via the Executive Board. The Assembly requested WHO to establish an international advisory committee on nursing and midwifery and to improve the network of

    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

    Context Peer-group deviance is strongly associated with externalizing behaviors. We have limited knowledge of the sources of individual differences in peer-group deviance. Objective To clarify genetic and environmental contributions to peer-group deviance in twins from mid-childhood through early adulthood. Design Retrospective assessments using a life-history calendar. Analysis by biometric growth curves. Setting General community. Participants Members of male-male pairs from the population-based Virginia Twin Registry personally interviewed in 1998–2004 (n=1802). Main Outcome Measure Self-reported peer-group deviance at ages 8 to 11, 12 to 14, 15 to 17, 18 to 21, and 22 to 25 years. Results Mean and variance of peer-group deviance increased substantially with age. Genetic effects on peer-group deviance showed a strong and steady increase over time. Family environment generally declined in importance over time. Individual-specific environmental influences on peer-group deviance levels were stable in the first 3 age periods and then increased as most twins left home. When standardized, the heritability of peer-group deviance is approximately 30% at ages 8 to 11 years and rises to approximately 50% across the last 3 time periods. Both genes and shared environment contributed to individual differences in the developmental trajectory of peer-group deviance. However, while the correlation between childhood peer-group deviance levels and the subsequent slope of peer-group deviance over time resulting from genetic factors was positive, the same relationship resulting from shared environmental factors was negative. Conclusions As male twins mature and create their own social worlds, genetic factors play an increasingly important role in their choice of peers, while shared environment becomes less influential. The individual specific environment increases in importance when individuals leave home. Individuals who have deviant peers in childhood, as a result of genetic vs

    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.

    Littile, C.Q.; Wilson, C.W.

    1996-01-01

    The ability to use an interactive world model, whether it is for robotics simulation or most other virtual graphical environments, relies on the users ability to create an accurate world model. Typically this is a tedious process, requiring many hours to create 3-D CAD models of the surfaces within a workspace. The goal of this ongoing project is to develop usable methods to rapidly build world models of real world workspaces. This brings structure to an unstructured environment and allows graphical based robotics control to be accomplished in a reasonable time frame when traditional CAD modelling is not enough. To accomplish this, 3D range sensors are deployed to capture surface data within the workspace. This data is then transformed into surface maps, or models. A 3D world model of the workspace is built quickly and accurately, without ever having to put people in the environment

  14. 'Living between two worlds': who is living in whose worlds?

    Science.gov (United States)

    McCoy, Brian

    2009-08-01

    Indigenous people have often been depicted as 'living between two worlds'. They have been described as living neither in their 'Indigenous' world nor in the 'Western' world but in some middle, liminal, or in-between 'world'. People in such situations are often described as 'caught' or 'suspended' and with obvious negative social, emotional and health consequences. What is this cultural space that is often described as 'being between two worlds'? Can Indigenous people develop their identity within the demands and values of contemporary Australian society? Most people who live within the context of modernity move across a mixture of different social, spiritual and cultural 'worlds'. By projecting particular and negative meanings onto Indigenous people and their journey of identity, non-Indigenous people diminish the value of Indigenous energies and initiatives in attempting to cope with life's diverse pressures and expectations. The perpetuation of such attitudes serves to undermine the efforts that Indigenous people make to engage modernity while at the same time attempting to maintain values that are of critical importance for their health and wellbeing. Consequently, non-Indigenous people can end up diminishing the importance of their own life transitions.

    For the first time since the political and economic opening of the former Soviet Union and Eastern Europe, world uranium production actually increased in 1995. Preliminary estimates for 1996 continue this trend, indicating additional (if slight) production increases over 1995 levels. Natural uranium production increased by about 5% in 1995 to 34,218 tons uranium or 89 Mlbs U3O8. This is an increase of approximately 1700 tons of uranium or 4.3 Mlbs of U3O8 over the updated 1994 quantities. Data is presented for each of the major uranium producing countries, for each of the world's largest uranium mines, for each of the world's largest corporate producers, and for major regions of the world

  3. World-wide environmental problems

    1975-01-01

    Man and the physical and natural resources necessary to support him in a civilized society are on a collision course. It is simple to say that man cannot continue to grow in number at an ever-increasing rate without a destructive effect upon the environment. Positive scientific proof for this impending calamity is not now available, yet many indications--sometimes physical and sometimes natural--point toward major world-wide environmental troubles in the near future. A number of environmental problems are described, particularly as they relate to the total world system. A computer model simulating future world-wide environmental trends from 1900 to 2100 A.D. is evaluated and suggested as a major tool for data-gathering purposes to determine the extent of world-wide environmental problems. It is suggested that scientists take an active role in the study of the environment, particularly in relation to man's future on earth

    2000-01-01

    This paper provides a description of the international energy projections elaborated with the POLES energy model for the purpose of analysing, in other papers of this issue, the impacts of technological change at world level and to 2030. Section 2 describes the key exogenous hypotheses on population and economic growth used for this projection, as well as the main resulting changes for the world energy system and in terms of CO 2 emissions. In Section 3 the dynamics of the energy systems are further analysed for four main world regions, while Section 4 is dedicated to the identification of the key uncertainties and of their possible impacts on future energy development. Finally, the last section presents the key messages of this outlook, which shows a rapidly growing world economy and energy consumption with increasing oil and gas prices, although this last feature remains subject to uncertainties on resource endowment estimates.

    The idea that “realism” is the common denominator across the vast range of productions normally labelled as “world cinema” is widespread and seemly uncontroversial. Leaving aside oppositional binaries that define world cinema as the other of Hollywood or of classical cinema, this chapter will test the realist premise by locating it in the mode of production. It will define this mode as an ethics that engages filmmakers, at cinema’s creative peaks, with the physical and historical environment,...

  14. Natural-gas world reserves and world resources

    International Nuclear Information System (INIS)

    Eickhoff, G.; Rempel, H.

    1995-01-01

    Natural gas is extracted in nearly 80 countries, 12 of which have a share of four fifths in the world extraction and 15 of which have a share of four fifths in the world consumption. The natural-gas world reserves can cover the present annual demand for years beyond the middle of the coming century. According to current assessments, the resources which presently cannot be extracted economically, the expected additional resources, and the extractable share in the potential of unconventional natural gas amount to more than ten times the reliable world reserves of natural gas. From the geological and technical points of view the world natural-gas extraction will not decrease or cease in the near future. However, the more expensive development of unconventional deposits which are located far away from the end-user will have to be preferred over the medium term on account of the exhaustion of the known deposits whose exploitation is comparatively cheap.

    1995-01-01

    In march 1994 the Central Planning Bureau (CPB) in the Hague, the National Institute of Public Health and Environmental Protection (RIVM) in Bilthoven and the Institute of Environmental Studies (IES) in Amsterdam started the first phase of a joint research program aimed at creating integrated scenarios of the global economy, GHG emissions, and climate impacts. The goal of the first phase of this project was to design and test a linked version of the economic model WORLD SCAN of the former, and the climate model IMAGE 2 of the latter institute. This first phase has resulted in the planned test runs with an operational version of the linked models by May 1995. The experiences in the first year were encouraging, both in the scientific and the organizational sense. In a sense, a link was made between scientific disciplines: a coupling of disciplines concerning with global economic development and the global physical climate system is difficult and novel. The goal of the project was to integrate long-term economic developments and effects of climate change. Both the WORLD SCAN model and IMAGE 2 provide a consistent analysis of the global system, but from different perspectives. IMAGE 2 simulates climate change and its effects in a global context but treats the economic system as exogenous. WORLD SCAN covers the world economic system in a consistent manner but does not take into account the global environment. The links are constructed in the area of agriculture and energy. The basic idea is that WORLD SCAN determines demand and supply on economic principles, while IMAGE 2 provides information on changes of land area and average quality of productive land, and other damage costs based on its three sub-systems. The demand for energy is fed into IMAGE 2's Energy Industry subsystem (EIS), which in turn determines emissions of greenhouse gases. Furthermore, some additional output from WORLD SCAN on activity levels, prices and capital structure can be used to determine

  16. World uranium supply and demand

    International Nuclear Information System (INIS)

    Patterson, J.A.

    1980-01-01

    The role of nuclear energy is under increasing scrutiny and uncertainty. None the less, there will be an increasing need for expansion of uranium supply to fuel committed reactors. Longer-term demand projections are very uncertain. Improved knowledge of the extent of world resources and their availability and economics is needed to support planning for reactor development, especially for breeder reactors, and for fuel-cycle development, especially enrichment, and reprocessing and recycle of uranium and plutonium. Efforts to date to estimate world uranium resources have been very useful but have largely reflected the state of available knowledge for the lower cost resources in regions that have received considerable exploration efforts. The IUREP evaluation of world resources provides an initial speculative estimate of world resources, including areas not previously appraised. Projections of long-range supply from the estimated resources suggest that the high-growth nuclear cases using once-through cycle may not be supportable for very long. However, additional effort is needed to appraise and report more completely and consistently on world resources, the production levels attainable from these resources, and the economic and price characteristics of such production.

    Le Jannic, N.

    2013-01-01

    The contribution of the green production to the world production of electricity reached 20.2% in 2011, it means a slight increase in respect to the figure of 2010: 19.8%. Green electricity is the second source of electricity behind fossil energy (67.9%) but before nuclear power (11.7%). The decrease in nuclear power due to the Fukushima accident has automatically benefited green electricity. The figures show the importance of China, China is now the first electricity producer in the world before US and also passed US for the production of green electricity. At the world scale the production of green electricity can break down into: hydro energy (80.5%), wind energy (10.3%), biomass (6.2%), geothermal energy (1.6%) and solar energy (1.4%). The crisis has slowed down the investment in renewable energies in Europe. (A.C.)

    State and prospects of the world power engineering development are considered. Eelectricity production requires the greatest part of the world total energy consumption. The latter will grow and in future at the beginning of the next century it reaches 50%. The part of NPPs in 1986 constituted 12% in power and 16% in electricity production. In the middle of 1987 403 NPP units of 298 GW total power were in operation in the world; 138 units (123 GW) were under construction and 84 units (84 GW) were planed. In 1987 power units of 216 GW total power were put into operation. The largest NPPs are Fukushima (Japan) - 9.0 GW, Bruce(Canada) - 8.4 GW, Gravelines (France) - 5.56 GW

    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.

    Klastrup, Lisbeth

    With gameworlds as the prime example, this article discusses online worlds as new forms of cultural entertainment systems and presents a framework with which to analyse them. The framework takes its point of departure in a discussion of what online gameworlds are, which genres of worlds exist and how they can be understood as a new form of engaging experience similar to the type of experience we have when we are captivated by the fictional universes of novels, films and tabletop roleplaying games. The proposed framework is grounded in an aesthetic, communicative and sociological approach to online worlds as digital phenomena, with the primary objective of describing how online gameworlds are systems that create meaning through the production of the experience of “worldness”.

    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.

    The World Bank Group regards excessive population growth as the single greatest obstacle to economic and social advance in the underdeveloped world. Since 1969 the Bank and the International Development Agency have provided countries with technical assistance through education, fact-finding, and analysis and given 65.7 million dollars for population projects. These projects, in India, Indonesia, Iran, Jamaica, and Malaysia provide training centers, population education, research, and evaluation as well as actual construction of clinics and mobile units. Because population planning touches sensitive areas of religion, caste, race, morality, and politics, the involved nation's political commitment to plan population growth is critical to the success of any program.

    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: Cancer can strike anyone at anytime, young or old, rich or poor. It knows no borders. World Cancer Day, on 4 February, was initiated to raise global awareness of cancer issues and stimulate new strategies and thinking to combat the killer disease. Nowhere is the need greater than in the developing world, where millions of people are suffering and dying due to lack of cancer prevention and treatment. According to the World Health Organisation (WHO), 84 million people will die of cancer in the next 10 years, more than 70% of them in low-income countries, unless action is taken now. The IAEA's Programme of Action for Cancer Therapy (PACT) was created to help poorer countries confront the growing cancer crisis by integrating radiotherapy into comprehensive cancer control programmes. As it celebrates its third birthday on World Cancer Day, PACT can claim significant progress in building effective relationships with a broad array of stakeholders, initiating six pilot projects and gaining increasing support from Member States. The IAEA commends all organizations, agencies and individuals engaged in the battle to defeat this dreadful disease. We look forward to continued collaboration with international partners to help bring hope to cancer patients, to relieve their suffering and to save lives. (IAEA)

    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.

    1981-01-01

    At the end of 1980 nuclear energy accounted for 9% of the world production of electricity stemming from 262 power stations, utilising mainly the process of water reactors and representing an installed capacity of 142 GWe. This production, apparently limited, already represents the equivalent of 150 million TOE. The 600 nuclear power stations in service, under construction or ordered represent a total of 450 GWe. In 1985, their production ought to cover 15% of the world requirements of electricity, which corresponds to a doubling of the share of nuclear energy within 6 years. During these recent years, the development of nuclear energy has undergone a significant slowing down and the number of orders for new nuclear power stations has dropped considerably in particular in the United States. Considering the time required and the available industrial capacity, the accumulated capacity which could be installed worlwide by 1990 could attain 530 GWe, equivalent to 650 MTOE covering 24% of the world production of electricity and 7% of the world consumption of primary energy. A determined effort for the end of this century could end up by the installation of 1200 GWe of capacity, generating 1.5 GTOE. The share of nuclear energy would then represent 35% of the production of electricity [fr

    Virtual globes have set the standard for information exchange. Once you've experienced the visually rich and highly compelling nature of data delivered via virtual globes with their highly engaging context of 3D, it's hard to go back to a flat 2D world. Just as the sawbones of not-too-long-ago have given way to sophisticated surgical operating theater, today's medium for information exchange is just beginning to leap from the staid chalkboards and remote libraries to fingertip navigable 3D worlds. How we harness this technology to serve a world inundated with information will describe the quality of our future. Our instincts for discovery and entertainment urge us on. There's so much we could know if the world's knowledge was presented to us in its natural context. Virtual globes are almost magical in their ability to reveal natural wonders. Anyone flying along a chain of volcanoes, a mid-ocean ridge or deep ocean trench, while simultaneously seeing the different depths to the history of earthquakes in those areas, will be delighted to sense Earth's dynamic nature in a way that would otherwise take several paragraphs of "boring" text. The sophisticated concepts related to global climate change would be far more comprehensible when experienced via a virtual globe. There is a large universe of public and private geospatial data sets that virtual globes can bring to light. The benefit derived from access to this data within virtual globes represents a significant return on investment for government, industry, the general public, and especially in the realm of education. Data access remains a key issue. Just as the highway infrastructure allows unimpeded access from point A to point B, an open standards-based infrastructure for data access allows virtual globes to exchange data in the most efficient manner possible. This data can be either free or proprietary. The Open Geospatial Consortium is providing the leadership necessary for this open standards-based data access

It is pointed out that the global disaster started with a seemingly small operation by Austria, which escalated uncontrollably into an all-destroying conflagration. A striking feature of the war was that none of the people who started it had any idea of what it would be like. Technology had changed the character of war, but old patterns of thought remained in place. We also examine the roots of the war in industrial and colonial competition, and in an arms race. Finally, parallels with current events, and the important lessons for today’s world are discussed.

    Some countries like Italy or Kazakhstan have given up nuclear power but others (Viet-Nam, Bangladesh, Egypt, Turkey) have the willingness to enter the nuclear world to sustain their development while complying with their environmental obligations. Others like United Arab Emirates, Belarus have their first reactor being built and other countries like France, Finland, United States, Slovakia, Brazil, Pakistan, India, Taiwan, South-Korea, China, Russia, Ukraine are reinforcing their reactor fleet by building new reactors. A total of 62 reactors is being built throughout the world with 22 in China. New construction of reactors, the dismantling of decommissioned installations and the integration of nuclear power in new economic models make the future brighter for nuclear industry. (A.C.)

In Canada the ten reactors in operation had a combined capacity of about 5.5 GW. Another 14 under construction will produce an additional 9.9 GW. Four Canadian reactors were in the world's top ten in terms of capacity factor in 1980, and six were in the top ten in terms of lifetime performance. Data tabulated for the Canadian reactors are: location, power, operator, date of first power. For the rest of the world, a table gives the number of reactors of each type and their capacity.

  7. Tuvan music and World Music

    Directory of Open Access Journals (Sweden)

    Maxim V. Chaposhnikov

    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

    2014-01-01

    The organization of the 2014 football world cup by Brazil is an opportunity to recall how the level of natural radioactivity can change from a country to another. Brazil is with Iran and India one of the 3 countries where the level of natural radioactivity is the highest. In Brazil the average value for natural radioactivity is about 10 mSv/year but you can find spots on the Brazilian 'planalto' where natural radioactivity ranges from 10 to a few tens of mSv/year. The mean value of natural radioactivity at the world scale is about 2.5 mSv/year. The value of 10 mSv/year is the radiation threshold that may trigger the evacuation of the local population in case of a nuclear accident in France. These various figures show that radiation dose limits are very low and should not be considered as representative of actual health hazards. (A.C.)

    1986 will inevitably go down in history as the year of Chernobyl, the consequences of which must be delays in and even withdrawals from the development of nuclear power. On the credit side, the Soviet Union has done a rapid and remarkable job in sealing the damaged reactor and rehabilitating the station and the area while improving the safety of its total program. Equally effective has been the response of the IAEA. In terms of nuclear power's claim as a major source of energy, nothing has changed as a result of Chernobyl. 15% of the world's electricity is now produced from nearly 400 power reactors. In comparison with any other energy form nuclear energy must rank high in terms of economy, safety and environmental effects. What has changed is the public perception of nuclear power, and the effort world-wide which will need to be made to restore public confidence

  11. Science in an Exponential World

    Szalay, Alexander

    The amount of scientific information is doubling every year. This exponential growth is fundamentally changing every aspect of the scientific process - the collection, analysis and dissemination of scientific information. Our traditional paradigm for scientific publishing assumes a linear world, where the number of journals and articles remains approximately constant. The talk presents the challenges of this new paradigm and shows examples of how some disciplines are trying to cope with the data avalanche. In astronomy, the Virtual Observatory is emerging as a way to do astronomy in the 21st century. Other disciplines are also in the process of creating their own Virtual Observatories, on every imaginable scale of the physical world. We will discuss how long this exponential growth can continue.

    Full Text Available The next horizons of human-computer interaction promise a whirling world of digital bytes, physical bits, and their hybrids. Are human beings prepared to inhabit such cyber-physical, adaptive environments? Assuming an optimistic view, this chapter offers a reply, drawing from art and art history, environmental design, literature, psychology, and evolutionary anthropology, to identify wide-ranging motivations for the design of such “new places” of human-computer interaction. Moreover, the author makes a plea to researchers focused in the domain of adaptive environments to pause and take a longer, more comprehensive, more self-reflective view to see what we’re doing, to recognize where we are, and to possibly find ourselves and others within our designed artifacts and systems that make the world move.

  14. World Energy Roadmap - A Perspective

    Energy Technology Data Exchange (ETDEWEB)

    Alharthi, A.A.; Alfehaid, M.A.

    2007-07-01

    The dialogue between energy consumers and producers that has been going on for the past fifteen years has revealed the basic parameters of the complex energy scene. While the consumers are concerned with security of supply, the producers have equal concern with access to markets. A common ground for the two groups is sustainable development because both aim at the continuous flow of oil to ensure continued economic growth. Both have valid concerns and share equal responsibility towards the world at large where competitive advantages available to both groups are employed to achieve global sustainable development. The key to achieving this goal in a world of competing and (to some extent) conflicting priorities is not only a sizable and irreversible investment by both groups, but also the desire to relax unwarranted regulations that have hindered progress in the energy industry.

  16. World uranium markets: an update

    International Nuclear Information System (INIS)

    Connor, M.J.

    1983-01-01

    The current state of the world's uranium market and its effect on US nuclear-fueled utilities is discussed. Major uranium-related issues that will confront US utility nuclear fuel managers in the coming years are presented, emphasizing the perspectives of supply, demand, world market adjustment, and US market restrictions on imports. It is stated that the US market is essential by non-US producers to help equilibrate an otherwise excessive supply which would cause chaos in the market. To avoid another ten-year boom/bust cycle, the US is urged to reexamine its position on long-term contracts - which permit greater price stability in contrast to the spot market and its price fluctuations. 13 figures, 6 tables

  17. The World as Evolving Information

    Gershenson, Carlos

    This paper discusses the benefits of describing the world as information, especially in the study of the evolution of life and cognition. Traditional studies encounter problems because it is difficult to describe life and cognition in terms of matter and energy, since their laws are valid only at the physical scale. However, if matter and energy, as well as life and cognition, are described in terms of information, evolution can be described consistently as information becoming more complex.

  19. 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.

    The rapid growth in demand for natural gas from a global perspective is documented in this paper. Low prices compared to other fuels and a return to normal winter temperatures is argued to be the cause of this increase in consumption. Natural gas production and prices for 1995 are discussed and forecasts made for future years, in particular the prospects for LNG in Asia. Data on energy growth and gas specific information in world markets are included. (UK)

  3. Serving the world's poor, profitably.

    2002-09-01

    By stimulating commerce and development at the bottom of the economic pyramid, multi-nationals could radically improve the lives of billions of people and help create a more stable, less dangerous world. Achieving this goal does not require MNCs to spearhead global social-development initiatives for charitable purposes. They need only act in their own self-interest. How? The authors lay out the business case for entering the world's poorest markets. Fully 65% of the world's population earns less than $2,000 per year--that's 4 billion people. But despite the vastness of this market, it remains largely untapped. The reluctance to invest is easy to understand, but it is, by and large, based on outdated assumptions of the developing world. While individual incomes may be low, the aggregate buying power of poor communities is actually quite large, representing a substantial market in many countries for what some might consider luxury goods like satellite television and phone services. Prices, and margins, are often much higher in poor neighborhoods than in their middle-class counterparts. And new technologies are already steadily reducing the effects of corruption, illiteracy, inadequate infrastructure, and other such barriers. Because these markets are in the earliest stages of economic development, revenue growth for multi-nationals entering them can be extremely rapid. MNCs can also lower costs, not only through low-cost labor but by transferring operating efficiencies and innovations developed to serve their existing operations. Certainly, succeeding in such markets requires MNCs to think creatively. The biggest change, though, has to come from executives: Unless business leaders confront their own preconceptions--particularly about the value of high-volume, low-margin businesses--companies are unlikely to master the challenges or reap the rewards of these developing markets.

  4. World View in Economic Science

    Directory of Open Access Journals (Sweden)

    Kyzym Mykola O.

    2017-09-01

    Full Text Available In the process of updating the economic model of society there arose the problem of eliminating contradictions in the development of economic science that do not allow us to solve problems of practice in proven ways. Although these contradictions and methods for their resolving are partially reflected in many scientific publications, methodological and practical justifications for a comprehensive study of the reserves of the economic science development by combining the provisions of philosophy and disciplines of the humanities are still relevant. The solution of the problem of unpredictability of functioning and development of the economy using such a combination of scientific disciplines can be ensured by applying the world view models that enable justifying the vector of attention of scientists in the subject area of the problem. The constructiveness of the interaction of scientists representing different ontological views of the world depends on improving of the conceptual and categorical support of their dialogue. A scientific world view in such a composition creates a basis, firstly, for a fruitful discussion of representatives of various disciplines having a common subject of research, and, secondly, for overcoming the institutional and cognitive barriers to professional mobility of scientists. It can also serve to develop the mobility of representatives of professional communities of researchers.

  5. Forecasting world natural gas supply

    2000-01-01

    Using the multi-cyclic Hubert approach, a 53 country-specific gas supply model was developed which enables production forecasts for virtually all of the world's gas. Supply models for some organizations such as OPEC, non-OPEC and OECD were also developed and analyzed. Results of the modeling study indicate that the world's supply of natural gas will peak in 2014, followed by an annual decline at the rate of one per cent per year. North American gas production is reported to be currently at its peak with 29 Tcf/yr; Western Europe will reach its peak supply in 2002 with 12 Tcf. According to this forecast the main sources of natural gas supply in the future will be the countries of the former Soviet Union and the Middle East. Between them, they possess about 62 per cent of the world's ultimate recoverable natural gas (4,880 Tcf). It should be noted that these estimates do not include unconventional gas resulting from tight gas reservoirs, coalbed methane, gas shales and gas hydrates. These unconventional sources will undoubtedly play an important role in the gas supply in countries such as the United States and Canada. 18 refs., 2 tabs., 18 figs

  8. La reducción del tráfico de automóviles: una política urgente de promoción de la salud A reduction in automobile traffic: an urgent health promotion policy

    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.

    To present an overview of the World Health Organization World Mental Health (WMH) Survey Initiative. The discussion draws on knowledge gleaned from the authors' participation as principals in WMH. WMH has carried out community epidemiological surveys in more than two dozen countries with more than 200,000 completed interviews. Additional surveys are in progress. Clinical reappraisal studies embedded in WMH surveys have been used to develop imputation rules to adjust prevalence estimates for within- and between-country variation in accuracy. WMH interviews include detailed information about sub-threshold manifestations to address the problem of rigid categorical diagnoses not applying equally to all countries. Investigations are now underway of targeted substantive issues. Despite inevitable limitations imposed by existing diagnostic systems and variable expertise in participating countries, WMH has produced an unprecedented amount of high-quality data on the general population cross-national epidemiology of mental disorders. WMH collaborators are in thoughtful and subtle investigations of cross-national variation in validity of diagnostic assessments and a wide range of important substantive topics. Recognizing that WMH is not definitive, finally, insights from this round of surveys are being used to carry out methodological studies aimed at improving the quality of future investigations.

    Full Text Available In the last decades, object-oriented approach was able to take a large share of databases market aiming to design and implement structured and reusable software through the composition of independent elements in order to have programs with a high performance. On the other hand, the mass of information stored in the web is increasing day after day with a vertiginous speed, exposing the currently web faced with the problem of creating a bridge so as to facilitate access to data between different applications and systems as well as to look for relevant and exact information wished by users. In addition, all existing approach of rewriting object oriented languages to SPARQL language rely on models transformation process to guarantee this mapping. All the previous raisons has prompted us to write this paper in order to bridge an important gap between these two heterogeneous worlds (object oriented and semantic web world by proposing the first provably semantics preserving OQLto-SPARQL translation algorithm for each element of OQL Query (SELECT clause, FROM clause, FILTER constraint, implicit/ explicit join and union/intersection SELECT queries.

  11. [Induced abortion: a world perspective].

    Henshaw, S K

    1987-01-01

    This article presents current estimates of the number, rate, and proportion of abortions for all countries which make such data available. 76% of the world's population lives in countries where induced abortion is legal at least for health reasons. Abortion is legal in almost all developed countries. Most developing countries have some laws against abortion, but it is permitted at least for health reasons in the countries of 67% of the developing world's population. The other 33%--over 1 billion persons--reside mainly in subSaharan Africa, Latin America, and the most orthodox Muslim countries. By the beginning of the 20th century, abortion had been made illegal in most of the world, with rules in Africa, Asia, and Latin America similar to those in Europe and North America. Abortion legislation began to change first in a few industrialized countries prior to World War II and in Japan in 1948. Socialist European countries made abortion legal in the first trimester in the 1950s, and most of the industrialized world followed suit in the 1960s and 1970s. The worldwide trend toward relaxed abortion restrictions continues today, with governments giving varying reasons for the changes. Nearly 33 million legal abortions are estimated to be performed annually in the world, with 14 million of them in China and 11 million in the USSR. The estimated total rises to 40-60 million when illegal abortions added. On a worldwide basis some 37-55 abortions are estimated to occur for each 1000 women aged 15-44 years. There are probably 24-32 abortions per 100 pregnancies. The USSR has the highest abortion rate among developed countries, 181/1000 women aged 15-44, followed by Rumania with 91/1000, many of them illegal. The large number of abortions in some countries is due to scarcity of modern contraception. Among developing countries, China apparently has the highest rate, 62/1000 women aged 15-44. Cuba's rate is 59/1000. It is very difficult to calculate abortion rates in countries

  12. Advanced Reactors Around the World

    2003-01-01

    At the end of 2002, 441 nuclear power plants were operating around the globe and providing 17% of the world's electricity. Although the rate of population growth has slowed, recent United Nations data suggest that two billion more people will be added to the world by 2050. A special report commissioned by the Intergovernmental Panel on Climate Change estimated that electricity demand would grow almost eight-fold from 2000 to 2050 in a high economic grown scenario and more than double in a low-growth scenario. There is also a global aspiration to keep the environment pristine. Because of these reasons, it is expected that a large number of new nuclear reactors may be operating by 2050. Realization of this has created an impetus for the development of a new generation of reactors in several countries. The goal is to make nuclear power cost-competitive with other resources and to enhance safety to a level that no evacuation outside a plant site would be necessary. It should also generate less waste, prevent materials diversion for weapons production, and be sustainable. This article discusses the status of next-generation reactors under development around the world. Specifically highlighted are efforts related to the Generation IV International Forum (GIF) and its six reactor concepts for research and development: Very High Temperature Reactor (VHTR); Gas-Cooled Fast Reactor (GFR); Supercritical Water-Cooled Reactor (SCWR); Sodium-Cooled Fast Reactor (SFR); Lead-Cooled Fast Reactor (LFR); and Molten Salt Reactor (MSR).

  13. 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

  14. Colour Perception in Ancient World

    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.

    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

    Henry David Thoreau was wholeheartedly in love with nature and he devoted almost all his life time to observation, appreciation and study of nature. Thus he formed a deep understanding of nature. In 1845, Thoreau began a two-year and two-month residence at Walden Pond. His life was lonely but full of fragrance. He wanted to live meaningfully, confront the essential facts of life and live a simple life. Based on the review of the literature related to this topic, this paper aims to study Henry David Thoreau’s spiritual world, especially reflected in his famous book-Walden.

    2004-01-01

    In Summer 2004, The World Energy Council published a Study on 'Sustainable Global Energy Development: the Case of Coal'. The Study aims at developing an internationally consistent reply to the question whether and to what extent coal use could be economic and sustainable in meeting global energy demand to 2030 and beyond. It covers markets, trade and demand, mining and combustion technologies, restructuring and international policies, and perspectives. It considers both, the contribution that coal could make to economic development as well as the need for coal adapt to the exigencies of security of supply, local environmental protection and mitigation of climate change.

    . In this theoretical model, world-cultural and power-political explanations are pertinent to different, mutually informing, and coexisting aspects of the script-writing process. As a corollary of our approach, we present a conceptual framework for the study of intra-IGO script-writing, which is contingent on three...... normative struggles: among IGO staff, within an IGO’s board of directors, and between the staff and the board. To empirically substantiate our arguments, we examine scripts on taxation and capital controls by the International Monetary Fund. We conclude by discussing the broader implications of our model...

    Full Text Available This article discusses the recent use in the Political Geography of the structuralist social theories. It is performed initially, a brief reflection on the depreciation (or appreciation of the utopias and Marxist concepts. The methodological foundations of geographical approaches based on the world-systems theory are analyzed. It is also questioned the relationship of these approaches with geopolitical analysis in the macro-scale. At last, abridged, there is a discussion about the links of imperialism and the regulation theory with the geography.

  4. LPG world supply and demand

    2008-01-01

    Over the course of this decade, the global LPG market has moved from being tight, where supply barely exceeded non-price sensitive demand, to the current market situation where supply growth has outstripped demand growth to such an extent that current fundamentals suggest that considerable length will prevail in the market over the near term. As is the case for many other energy commodity markets, the LPG industry has experienced a considerable transformation over the last five years with many new LPG supply projects coming on-stream and demand growth in many developing markets slowing in response to higher energy prices. The near term challenge for LPG producers will be securing outlets for output as the market becomes increasingly oversupplied. With expanding LPG supply and a worldwide tightness in the naphtha market, it is expected that petrochemical consumers will favor relatively low priced LPG over naphtha and the resulting increase in LPG cracking rates will go some way to reducing the expected supply surplus. However, the timing of several new LPG supply projects and the start-up of LPG-based petrochemical plants in the Middle-East are expected to impact global LPG trade and pricing over the next few years. Thus, at this point in time, the global LPG market has a high degree of uncertainty with questions remaining over the impact of high energy (and LPG) prices on traditional and developing market demand, the timing of new supply projects and the combined effect of these two factors on international LPG prices. World LPG production has been rising in nearly every region of the world over the last few years and totaled about 229 million tons in 2007, which is some 30 million tons per year higher than in 2000. The exception is North America which accounts for the largest share of global LPG supply at about 24% but production there has remained relatively flat in recent years. Strong LPG production growth in the Middle-East which contributed to about 19% of

    State of the World 1999 presents evidence of the birth of an entirely new economy, an Environmental Revolution that may be as sweeping as the Industrial Revolution that put us on our present unsustainable course. The authors argue that, far from being too costly to consider, the transition to an environmentally sustainable economy represents the greatest investment opportunity in history. In country after country, community after community, people are making the changes needed to shift from today's fossil fuel-based, auto-centric, throwaway economy to a solar/hydrogen-powered, bicycle/rail-centered, reuse/recycle economy--an economy that will satisfy human needs while preserving the Earth's ecosystems

  6. The lost worlds of antimatter

    Given that matter can exist in two forms, each the mirror image of the other which annihilate each other on contact, producing energy, Dirac's cosmological model explains why there is no conspicuous antimatter in the world since it cannot co-exist with ordinary matter. However, if the creation of matter is always accompanied by an equal and opposite quantity of antimatter, how has all the material of the Universe come into existence without being infested by its mirror substance. The question of whether Grand Unified Theories can bring about an imbalance between matter and antimatter in the primeval Universe is considered. (UK)

    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...

  9. Panorama 2010: World coal resources

    Bessereau, G.; Saniere, A.

    2010-01-01

    At a time when the international community must face the key challenges posed by global warming as well as sustainability in general and many of our fellow citizens have come to look unfavorably upon fossil energies, the world is still heavily dependent on these energies to cover growing global energy demand. With proved reserves equivalent to more than 120 years at the present rate of extraction, with a better worldwide geographical distribution than petroleum, coal seems like an especially secure energy. While the renewable energies are showing rapid growth but still only represent a small proportion of the world energy mix, coal was the energy whose consumption grew at the fastest rate and for the sixth consecutive year. This gives cause for concern when one realizes that coal is also the most environmentally harmful energy at local level (its extraction generates pollution) and globally (its combustion emits CO 2 ). So how is it possible to reconcile the apparently irreconcilable, especially when, in some countries, coal represents the bulk of the energy resources? Since it is impossible to do without coal, the solution is to develop new 'clean coal' technologies, among which the capture and storage of CO 2 looks like a promising pathway. In the process, it will be necessary to overcome major technical, economic and social challenges. (author)

  10. Spain. Women in the world.

    Galindo, E; Serrano, N

    1994-08-01

    Spanish women live almost 2 times longer today than did their great grandmothers (60-65 years vs. 35). Contraception is more accessible, resulting in fewer pregnancies and their complications. The National Health Service of Spain provides women and their families medical care. Yet, women's health risks continue. Class, race, and geography result in women having uneven access to medical care. Primary health care services are not a priority as are high- technology hospitals. Women, who already lead a busy life, still care for older people or people with disabilities. Many households have a very limited or no income and depend on welfare benefits or family. There are more women than men who are poor because women, many of whom are single, are raising large families and many live alone. Women are often the victims of violence and of domestic abuse (1993, 86 violent deaths and 200,000 cases of abuse by a partner). Spain has laws that protect women facing divorce and that allow abortion, but men have created the world order. Women suffer daily in a world which does not recognize rape and sexual harassment as war crimes (e.g., former Yugoslavia). In Seville, the Solidarity Network of Women in Black is a pacifist group working to stop violence. They plan on setting up links to publicly denounce and act against all aggression and to institutionalize women's right to full freedom. War is destroying women's lives.

  11. News from the gas world

    Mr Pierre Gadonneix, President of Gaz de France, presented 'The Gaz de France Group in the new European context: opportunities and strategy of a major gas operator' during the 21. world gas congress, which was held in Nice from 6. to 9. June 2000. A few weeks from the liberalization of the gas market in Europe. It seems interesting to publish this article, which very pertinently presents the point of view of the leading French gas operator. We also considered it right to publish the presentation of Mr Burckhard Bergmann, President of Eurogas, who presented the European vision. To complete this panorama of the gas situation, we are also publishing news about the international gas situation in 1999, written by Marie-Francoise Chabrelie of Cedigaz which is summarized here under: in a changing environment, characterized by privatisation, the deregulation and the opening up of markets (Europe, Australia), natural gas has progressively gained ground in the world energy market. This trend was confirmed in 1999. Major discoveries open the way to new projects for local use and export. In spite of the uncertainties regarding the situation in countries of the ex-Soviet Union, several favourable factors, including economic recovery in Asia faster than forecast, indicate a growth hypothesis ranging from 2.5% for this year.

    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.

  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.

  14. Cofactors in the RNA World

    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.

  16. Nutrition: the new world disorder.

    Science.gov (United States)

    Cannon, Geoffrey

    2002-01-01

    Scale up 'we are what we eat' and nutrition is revealed as an aspect of world governance. The quality and nature of food systems has always tended to determine not only the health and welfare but also the fate of nations. The independence of nations depends on their development of their own human and natural resources, including food systems, which, if resilient, are indigenous, traditional, or evolved over time to climate, terrain and culture. Rapid adoption of untested or foreign food systems is hazardous not only to health, but also to security and sovereignty. Immediate gain may cause permanent loss. Dietary guidelines that recommend strange foods are liable to disrupt previous established food cultures. Since the 1960s the 'green revolution' has increased crop yield, and has also accelerated the exodus of hundreds of millions of farmers and their families from the land into lives of misery in mega-cities. This is a root cause of increased global inequity, instability and violence. 'Free trade' of food, in which value is determined by price, is imposed by dominant governments in alliance with industry when they believe they can thereby control the markets. The World Trade Organization and other agencies coordinate the work of transnational corporations that are the modern equivalents of the East India companies. Scientists should consider the wider dimensions of their work, nutrition scientists not least, because of the key place of food systems in all societies.

  17. World energy use - 2000 developments

    2001-01-01

    The paper is presenting the analysis of World energy consumption in the year 2000. Special emphasis is given to the contribution of primary energy use to the global greenhouse effect. The analysis is based on data published by British Petroleum. It is also an update of my analysis published at the same conference one year ago. It can be seen that nuclear power is still the fastest growing primary energy sector in the World, that its share in primary energy mix is increasing and that it is even the fastest increasing share of all sources. Nuclear consumption in Europe is still increasing, but surprisingly the use of coal has increased too in the last year. Consumption is rapidly increasing in North America, while nuclear share there is still fastest growing. In Asia the rate of nuclear growths has slowed down in the last year, gas is now the fastest growing primary energy source. In countries of the former Soviet Union the nuclear energy is the only sector that has reached the level of production of ten years ago. It is worrying that in the countries of OECD the coal consumption is increasing again. Finally, it is also very worrying that the overall consumption of fossil fuels worldwide is increasing. What will happen with the greenhouse effect?(author)

  18. Aging in the Third World.

    Science.gov (United States)

    Hugo, G

    1987-01-01

    The relationships between the generations in Third World countries are changing as migration and industrialization erode traditional family responsibilities for supporting the elderly. It is no longer possible to assume that, as a matter of course, old people will be looked after by their families. Social change leads to an eroding of the support systems. The author finds growing evidence of this breakdown in Asia, particularly in Singapore, Hong Kong, and other highly industrialized centers. Singapore, for example, has reinstituted the compulsory study of filial piety in an attempt to push the younger generation into assuming its traditional responsibility toward the old. There has also been a significant decline in the status, prestige, and support given old people in Indonesia, although politicans insist that the family will always take care of its elderly. 2 reasons for this breakdown are 1) the impact of the mass media and 2) the increasing involvement of the younger generation in non-agricultural jobs which often involve a move to the city and away from dependence on a patriarch. Many Third World countries are in a twilight stage, between the traditionally strong structure of family support and government systems of social security.
