    Full Text Available El presente artículo se centra en analizar desde una perspectiva teórico-práctica el comportamiento del riesgo crediticio, calce de plazos y tasas de interés en el conjunto de la banca comercial y universal venezolana para el trienio 1998-2000, años éstos donde las políticas económicas experimentaron comportamientos de diferente corte. A través de una investigación de tipo descriptivo-observacional, los resultados revelan que este importante segmento del sector financiero presentó una exposición al riesgo de calce de plazos al obtener pasivos conformados por depósitos a corto plazo en relación a la tenencia de activos en préstamos a mediano y largo plazo. Igualmente se concluye, el buen desempeño del entorno económico reduce las posibilidades que el sistema financiero se enfrente al riesgo crediticio, dada la mejor posición financiera de los agentes económicos demandantes de fondos prestables. Por su parte, el riesgo de tasas de interés no estuvo presente en el sistema bancario venezolano durante el periodo de estudio, dada la disposición por parte de las políticas monetarias en tratar de bajar el diferencial entre las tasas de interés activas y pasivas, sin que este diferencial se tornara negativo para este importante sector del sistema financiero venezolano.

El nuevo marco constitucional, surgido de la aprobación de la Constitución de la Republica Bolivariana de Venezuela de 1999, los lineamientos establecidos en los Planes de la Nación 2001-2007 y 2007-2013, y la manifestación de contradicciones entre la práctica financiera y los objetivos de política pública, se constituirán en el curso del período, en condicionantes permanentes de las transformaciones institucionales del sistema financiero. El objetivo de esta investigación es explicar los cambios institucionales que se han producido en la banca pública venezolana y los resultados alcanzados en relación a los objetivos de la política económica. Mediante una investigación documental con diseño bibliográfico, se explica la experiencia venezolana de transformación de la banca pública y la política pública definida para producir esos cambios, considerando el uso de la capacidad de apalancamiento del sistema financiero como elemento de democratización financiera y dinamizador del desarrollo nacional.

    Full Text Available Con el apoyo de herramientas de análisis de estados financieros, el presente artículo busca contrastar los rasgos de la estructura económica y financiera de las Pequeñas y Medianas Empresas Manufactureras de la zona fronteriza colombo-venezolana, más específicamente de Cúcuta y San Cristóbal, respectivamente, durante los años 2009 al 2012. La investigación es descriptiva, documental, con muestreo intencional. Entre los principales hallazgos destaca que las empresas venezolanas estudiadas concentran su estructura económica en partidas no monetarias, aplican políticas conservadores de crédito y se financian principalmente con la banca ante tasas de interés reales negativas. En contraparte, las empresas colombianas mantienen una proporción mucho mayor en cuentas monetarias, flexibilizan sus políticas de crédito y se financian mayormente por la vía comercial. Se concluye que el escenario macroeconómico impacta en la estructura económico-financiera de las organizaciones; estas deben ajustarse buscando mantener su efectividad. Aun cuando el parque industrial de San Cristóbal genera comparativamente mejores resultados, en términos de rentabilidad y beneficio, estos se inciden negativamente ante un ambiente de creciente inflación.

    Full Text Available Actualmente se evidencia en España una reorientación solidaria de una parte de la oferta de servicios financieros, que prioriza el compromiso social de su actividad sin descuidar, por ello, la viabilidad económica. Este modelo de hacer banca se identifica bajo la denominación genérica de banca alternativa, ética, social o solidaria y constituye un planteamiento bancario distinto del enfoque tradicional. Este trabajo pretende destacar la idoneidad de la sociedad cooperativa para el desarrollo de banca alternativa. Su naturaleza jurídica y sus normas de funcionamiento permiten potenciar la utilidad social de la actividad bancaria. La dualidad de sus socios elimina eslabones de la cadena de intermediación y destina los recursos propios a la financiación de proyectos socialmente responsables, en un camino en el que la economía financiera y la economía real avanzan muy próximos./Currently in Spain we are witnessing an ethical reorientation of a part of the offer of financial services which gives priority to the social commitment without losing economic viability. This banking model known as alternative banking also known as ethical, social or sustainable banking is distinct from traditional banking. This work wishes to highlight the ideal conditions of cooperatives for the development of alternative banking. Its legal nature and its functional regulations enhance the social utility of the banking activity. The double condition of the partners eliminates intermediaries and allocates directly equity towards financing socially responsible projects, in a way that the financial economy and the real economy advance together.

Knowing that a guardian is in the commitment and obligation to assist the student, from beginning to realize their research project, to ensure the successful presentation. In our universities, this situation has become a serious problem, since, in many cases, students finish their education and fail to graduate, either, because either could not find a tutor, or began to work with some, but left the student in the research process. This series of eflections puts us in a position of analysis that allows us to think of a proposal or model for the Venezuelan university tutor and set parameters in order to change this problem.

    Full Text Available Se analiza la estructura de la banca comercial en México y los principales indicadores de rentabilidad y eficiencia operativa en los años recientes. Se pretende precisar cuáles son los determinantes de los rendimientos y de las condiciones de operación, así como la vinculación entre éstos; en especial se evalúan los factores de tamaño y concentración del mercado, apalancamiento, márgenes por intereses, márgenes por operación, y utilidades netas. Los resultados muestran diferencias significativas entre los bancos de acuerdo con su tamaño: la banca comercial exhibe una evolución no homogénea. Si bien los bancos que generan más utilidades son los bancos grandes y los medianos, los primeros son eficientes por sus amplios márgenes netos de intereses y margen de operación, mientras que los bancos medianos derivan sus utilidades de su rotación de activos y elevado apalancamiento. El documento expone también los cambios ocurridos en la estructura del sector como consecuencia de la liberalización financiera, privatización y entrada del capital extranjero que ocurrió en la década de los noventa.

Los resultados indican a las aves silvestres como las más tratadas en piezas musicales tanto en Europa como en Venezuela; manifiestan también una proporción mayor de piezas musicales que tratan los animales de producción versus animales domésticos en Venezuela, mostrándose lo contrario en el continente europeo. Se concluye, en primer lugar, que tanto en Venezuela como en Europa, la cultura humana busca enaltecer la fauna silvestre, ya sea de forma naturalista o romántica; se confirma el fuerte arraigo de la mentalidad agropecuaria venezolana y su importancia en el desarrollo de la cultura nacional a la par que en Europa; los resultados reflejan el poco contacto con áreas verdes abiertas y sistemas de producción agropecuarios que poseían los compositores y público académico de la época. Esta investigación fomenta la interdisciplinariedad en la sociedad científica venezolana, haciendo aportes científicos al desarrollo de la cultura, además de servir a docentes, terapeutas musicales, historiadores y la sociedad en general en sus investigaciones y ocupaciones al generar nuevas preguntas en el campo científico de la psiquis humana dentro de la relación hombre/animal y brindar nuevos conocimientos a la ciencia histórica de la Medicina Veterinaria y la Música Universal.

Los hallazgos encontrados indican que las herramientas utilizadas con mayor frecuencia son los servicios de explotación, teniendo una notoria debilidad en la definición de los procesos realizados. Esto genera un gran impacto en la toma de decisiones, para proporcionar respuestas a interrogantes del negocio. Se concluye el uso de la inteligencia de negocios como un sistema de apoyo a los procesos llevados a cabo en las instituciones estudiadas.

    Full Text Available Este trabajo revisa la noción de antiimperialismo que puede deducirse de la lectura de algunas novelas venezolanas cuyo relato se ubica en el periodo de implantación de la industria petrolera. A tal fin, se atiende de modo particular a la presencia de nuevas tecnologías percibidas, en general, como parte de la avanzada neo colonizadora en que se convirtió, para la mayoría de los escritores venezolanos del momento, la presencia de las compañías extranjeras. Se centran estas reflexiones básicamente en tres obras: Mene de Ramón Díaz Sánchez, Mancha de aceite de Cesar Uribe Piedrahita y El señor Rasvel de Miguel Toro Rámirez, estas dos últimas, a diferencia de la primera, muy mal conocidas en el ámbito tanto venezolano como latinoamericano.

    Full Text Available La organización sistémica es una configuración socio-técnica desarrollada por la banca a nivel global durante las últimas décadas, cuyos componentes fundamentales son: por un lado, la organización en red lo que implica procesos de informatización, sistematización interna y entrelazamiento permanente entre redes de proveedores y clientes, con diversos grados de interconexión, en ambientes sumamente competitivos; y, por otro lado, la flexibilidad organizativa tanto interna como externa (Ibarra, 2003; Nohria y Eccles, 1992; Weiss, 2008, Weiss et al., 2010. El objetivo de la investigación fue indagar en qué medida la banca colombiana se configura como una organización sistémica. Se concluye que a pesar de la heterogeneidad en el uso de tecnologías de información y comunicación (TIC´s, la banca tiende a consolidarse como un tipo de organización sistémica, transformando de manera significativa la relación con los clientes, los proveedores, la organización del trabajo, los perfiles de los trabajadores y las relaciones laborales. Desde la perspectiva metodológica de la triangulación, se integran técnicas cualitativas (entrevistas y grupos de discusión y cuantitativas (encuesta, en un sentido de complementariedad de los dos métodos.

    2006-01-01

    Full Text Available Esta investigación tiene como objetivo analizar la pertinencia de la noción de capacidades societales de innovación en corporaciones venezolanas. La investigación es de tipo analítica y su diseño es no experimental. Se utilizó la técnica de observación documental. Los resultados se basan en que las corporaciones en general no hacen explicita su responsabilidad de crear y facilitar las condiciones para la construcción de capacidades societales de innovación de actores socio económicos tradicionales y no tradicionales. En este sentido, la escasa responsabilidad como difusor de innovaciones de las corporaciones venezolanas se debe a las limitaciones y precariedades en la formación gerencial con vocación industrial del empresario. La conclusión más importante radica en que la noción de capacidades societales manejada resulta inexhaustiva para dar cuenta de los procesos innovativos de corporaciones venezolanas.

    Full Text Available La timidez con la que comenzaron a internacionalizarse los bancos españoles, integrantes tanto del actual grupo BBVA como del Santander, aplicando estrategias defensivas y reducidos volúmenes de recursos y riesgos comprometidos, difícilmente hacían presagiar la intensidad y agresividad que ha adquirido en las dos últimas décadas, y que han convertido a dicho proceso en una decisión estratégica de crecimiento para la gran banca española.De forma gradual, tanto el BBVA como el Santander, se han introducido en los principales mercados de Latinoamérica y en los más cercanos e importantes de la Unión Europea. De una implantación generalizada de banca comercial en los noventa, sobre Latinoamérica, se ha pasado a operaciones selectivas en términos operativos y geográficos; llegando a finales de 2007, a liderar diferentes servicios bancarios y parabancarios en la mayor parte de los países del área, con especial incidencia en Brasil, donde el Santander está especializando sus inversiones, y en México, donde el BBVA ha consolidado su implantación y, desde el que se ha servido para iniciar actividades bancarias en el sur de los Estados Unidos. La mayor dimensión internacional del Santander le ha colocado también en posiciones líderes en los mercados ibérico, británico y en el segmento de financiación al consumo en la Europa Comunitaria.The timidity with which they began to internationalize Spanish banks, both members of the current group BBVA and Santander, of applying defensive strategies and reduced volumes of resources and risks involved, hardly did presage the intensity and aggressiveness that has gained in the last two decades, and they have turned the process into a strategic decision to growth for the Spanish banking.Gradually, both BBVA and Santander, has been internalised in the main markets of Latin America and the closest major of the European Union.

    2011-01-01

    Full Text Available La confianza se ha convertido en un importante desafío para la banca en Internet. El hecho de que muchas personas aún no adopten Internet para realizar sus operaciones bancarias, se debe entre otras causas, a la poca confianza que aún existe hacia este sistema. Esta desconfianza, podría estar relacionada con la familiaridad y con el grado de seguridad que las personas perciben de este sistema bancario. El objetivo de este estudio es analizar el efecto que la familiaridad y la seguridad percibida tienen sobre la confianza hacia la banca en Internet. Las hipótesis planteadas, se contrastan a través de un modelo estructural, construido a partir de una serie de constructos fiables y válidos. Las principales conclusiones de este estudio, son que tanto la familiaridad como la seguridad percibida, tienen un efecto directo y positivo sobre la confianza. Al final del estudio, se presentan las implicaciones que estos resultados pudieran tener para la gestión de los factores determinantes de la confianza hacia la banca en Internet.

    Full Text Available La responsabilidad social empresarial –RSE– o responsabilidad social corporativa –RSC–, como algunos autores la citan, es un campo de estudio que en los últimos años se ha ido incorporando a la estrategia de las organizaciones. Este nuevo campo de estudio ha sido definido como el compromiso voluntario de las organizaciones por las actividades sociales y medioambientales, además de las económicas. El sector bancario no ha sido ajeno a la penetración que ha tenido la RSE en la gestión de las organizaciones, a tal punto que ya se mencionan términos como banca socialmente responsable, del cual hacen parte los términos banca ética y banca sostenible. El estudio describe los aspectos que marcan la diferencia entre los bancos europeos que se encuentran en la base de datos ASSET4, tomando como variables del estudio las calificaciones otorgadas por la base de datos a las acciones de responsabilidad social empresarial; igualmente, se utilizaron variables financieras y macroeconómicas. Entre los principales resultados de un análisis de conglomerado se encuentra que existe una alta correlación entre las acciones medioambientales y las acciones sociales en los bancos y que las acciones en responsabilidad social no muestran una correlación entre las variables financieras y las variables macroeconómicas.

  7. Diferencias entre universidades privadas y oficiales venezolanas: Algunos ajustes necesarios en el sector privado

    Directory of Open Access Journals (Sweden)

    Luis Fuenmayor Toro

    2003-01-01

    Full Text Available Este trabajo efectúa una caracterización preliminar de la universidad privada venezolana, a medio siglo de sus inicios. Se determinan algunas de sus fallas principales y propone correctivos factibles aprovechando las leyes de educación próximas a ser aprobadas. Los datos demuestran que las universidades privadas, a diferencia de las oficiales, tiene una planta docente mayoritariamente a tiempo convencional, ubicada principalmente en los más bajos escalafones académicos, con estudios de postgrado en una proporción menor que las universidades oficiales y prácticamente sin investigadores. La relación alumno/profesor es el doble de la del sector oficial y los postgrados universitarios que ofrecen son la quinta parte del total y sólo están acreditados el 10%, en contraposición con el 29% acreditado de las instituciones públicas. De estas comparaciones se extrae que la universidad privada está muy limitada para la realización de investigación y para el desarrollo de los postgrados que forman investigadores: maestrías y doctorados. Tiene además limitaciones subsanables en el pregrado, por no disponer de docentes contratados a altas dedicaciones, que dispongan de tiempo dentro de su dedicación para las consultas estudiantiles. Esto se puede resolver a través de un mandato legal que determine que un 33% de los docentes, sin contar autoridades y directivos, deban estar a dedicación exclusiva y repartidos homogéneamente entre todos los programas docentes institucionales. Estos docentes, también por mandato legal, dispondrían de un 30% de su tiempo para hacer investigación en unidades de universidades y otros centros oficiales, a las que serían adscritos formalmente. Ello mejoraría la academia de las instituciones privadas sin costos que hagan imposible estos importantes cambios.

    Full Text Available La Encefalitis Equina Venezolana (EEV es una enfermedad infecciosa, causada por un arbovirus de la familia Togaviridae, es transmitida del caballo o aves al hombre a través de picaduras de mosquitos, constituyendo una zoonosis. Cuba presta colaboración internacionalista en países donde esta enfermedad es endémica y considerada peligrosa, desde el punto de vista económico y sanitario. Se realizó  un estudio epidemiológico, para determinar la vulnerabilidad de introducción y transmisión local de la Encefalitis Equina Venezolana en el Área de Salud Delicias en el año 2009. Se utilizaron las siguientes variables: país de procedencia del colaborador, géneros de culícidos transmisores, población equina y se determinaron zonas de riesgo. Se identificaron tres países endémicos, el que mayor cantidad de colaboradores tuvo fue Venezuela, con 66 (85,7%, seguido de Ecuador y Haití, que solo tuvieron 1 (1,3%. El Consejo Popular 3 es el que más colaboradores en zonas endémicas poseyó (50, para un 87,7%. En el área se identificaron 11 géneros de mosquitos, de ellos cuatro transmisores de la EEV (Culex, Mansonia, Psorophora, y Anopheles, la población de equinos se distribuye en todo el territorio. Constituyen las zonas de mayor riego para la transmisión local de la enfermedad la parte noreste del poblado de Delicias y el poblado de San Manuel, determinándose 12 comunidades atendidas por Consultorios Médicos de Familia de alto riesgo para la transmisión local.

    Full Text Available Gongylolepis is composed for 15 species, endemic to the Guyana region. This is the largest genus of tribe Mutiseae in the area. Palynological features have been studied for some members of the Mutiseae, but not for Gongylolepis. We studied the pollen morphology of nine species of the genus, using samples from herbarium material. The observations were made in 10 to 15 pollen grains for species and features of the spines, colpus, polar axis, equatorial diameter, exine structure, pollen type, apertures, perforations and P/E ratio to determinate pollen shape, were analyzed. Observations and pictures were made with light microscope and scanning electron microscope. With this information, a matrix and conglomerate analysis was made. Gongylolepis pollen is tricolporate, spheroidal and mainly of great size. Differences in exine ornamentation were enough to discriminate the studied species. Spines are conical, with perforations near of the base, but with differences in the apex shape. The dendogram showed four groups, where the size, shape, exine ornamentation, spines, colpus and perforations were of importance to the classification of the species considered.Gongylolepis está constituido por 15 especies, circunscritas a la región de Guayana, al norte de Suramérica. Es el género más numeroso de la tribu Mutisieae en dicha región, representado en su flora por especies endémicas. Aunque algunas especies de Mutisieae han sido estudiadas palinológicamente por varios investigadores, no hay estudios de las especies de Gongylolepis. En este trabajo se analizan los caracteres morfológicos del polen de nueve especies de Gongylolepis, de la Guayana venezolana. Las muestras de polen provienen de material de distintas colecciones de herbario. Para la observación de los caracteres de polen se usaron de 10 a 15 granos por especie, se analizaron caracteres de las espinas, colpos, eje polar, diámetro ecuatorial, ornamentación y grosor de la exina, tipo de

    Full Text Available Economists and policy makers in Europe and the United States have devoted increasing attention towards the German financial system. In the new Single European Market, the German financial system, characterised by universal banking with unrestricted entry into all types of financial market, is expected to become the dominant form. The German kind of financial system has also been suggested as an alternative to the segmented US financial system. It is argued that the success of the German system has less to do with the freedom granted to universal banks than with its approach to regulation and supervision.   JEL Codes: G21, G18Keywords: Financial system, SEM

    Full Text Available Este trabajo tiene como propósito comparar la gestión de la investigación en la universidad pública venezolana durante el período 2004-2008, de acuerdo a visión sistémico-compleja de Pacheco et al (2002. La gestión se estudió desde los objetivos y estrategias; prácticas directivas; estructura y organización; métodos, instrumentos y herramientas, y cultura y personalidad. Se trabajó bajo un enfoque cualitativo, la recolección de la información se hizo a través de observación, realización de entrevistas y revisión documental utilizando como herramienta de análisis la hermenéutica. Se seleccionaron cuatro unidades de análisis, atendiendo al criterio de liderazgo en investigación en el ámbito nacional, éstas son: Universidad de los Andes (ULA, Universidad Central de Venezuela (UCV, Universidad Simón Bolívar (USB y Universidad del Zulia (LUZ. Por otro lado, el período 2004-2008 obedece a que es la última gestión rectoral finalizada y por tanto susceptible de ser analizada. Los resultados revelan que 1 De las universidades estudiadas, ULA; UCV y LUZ manejan modelos de gestión burocráticos y centralizados, con ciertas particularidades, mientras que, el de la USB es flexible y menos centralizado. 2 Aun cuando la USB exhibe mayor fortaleza general en investigación, se evidenciaron prácticas puntuales en ULA, LUZ y UCV que convendría replicar en el resto de las universidades. Se concluye, en primer lugar, que para las universidades tradicionales, es un imperativo cambiar el modelo de gestión dominante que frena el desarrollo de la investigación; en segundo lugar, si las universidades hacen sinergia entre las mejores prácticas de cada una, podrían catapultar la investigación universitaria venezolana y colocarla en el mapa mundial, haciéndola más independiente del gobierno de turno desde el punto de vista financiero.

    Full Text Available Se presenta un estudio de la vulnerabilidad sísmica de tres modelos estructurales de mediana altura proyectados según la norma venezolana Covenin 1756-01. Los modelos tienen similares configuraciones en planta y en alturas de entrepiso; en la acción sísmica se utilizaron acelerogramas híbridos, compatibles con el espectro de diseño característico de la zona metropolitana Barquisimeto-Cabudare. El daño se evaluó mediante curvas de fragilidad e índices de daño, incluido el enfoque probabilista. Algunos modelos mostraron altas probabilidades de daño severo o colapso, sufriendo deformaciones laterales y degradaciones de rigidez significativas más allá de límites aceptables normativos, evidenciando que los desplazamientos relativos, y la rigidez son indicadores fundamentales del daño estructural. Se concluyó que para evaluar el comportamiento de los modelos estructurales analizados, sometidos a la acción sísmica probable, se requiere de un detallado estudio de los desplazamientos horizontales, particularmente de los desplazamientos relativos entre niveles, y que las previsiones de la norma venezolana podrían no ser suficientes para la evaluación del desempeño sísmico de estos modelos. Here is presented a study on the seismic vulnerability of three mid-rise structural models projected according to Venezuelan seismic code Covenin 1756-01. Models have similar structural configurations in plant and in inter-sory heights. Seismic action uses hybrid accelerograms compatible with the design spectrum characteristic of the metropolitan area Barquisimeto-Cabudare. Damage Evaluation is made through fragility curves and damage indices, including probabilistic approach. Some models showed high probability of severe damage or collapse, suffering significant stiffness degradation and lateral deformations beyond normative limits, showing that relative displacements and stiffness degradation are fundamental indicators for structural damage.

    Full Text Available Por lo general se piensa que los problemas económicos venezolanos solamente pueden ser descritos por la denominada síntesis neoclásica. Existió a finales del siglo XIX y el siglo XX una serie de aportes que desafiaron las ideas keynesianas y de la Nueva Macroeconomía Clásica desde un punto de vista praxeológico,desligado de la teoría cuantitativa del dinero y consideraba la idea de los precios relativos. En tal sentido se revisó los aportes realizados por Mises (1982 [1912], (2005 [1936] y Hayek (1967[1931] en el tema de los ciclos económicos para realizar una aproximación a los problemas que afectan la economía venezolana. Se concluye que el impulso monetario en el marco de una economía rentística, de políticas públicas intervencionistas y el crédito blando, en un escenario de pocas empresas creadoras de bienes de inversión, generó distorsiones en el sistema de precios, de incentivos a la producción, aumento de las importaciones y deterioro del tipo de cambio; es decir, todo aquello que está en contracorriente con la búsqueda del desarrollo económico.

El modelo presentado permite construir una clasificación de la influencia personalista de los candidatos, como resto no explicado por una competencia ideológica espacial. Además de clasificar a los candidatos de las tres últimas elecciones presidenciales por su influencia personal, se ofrecen previsiones para futuros comicios tomando como base el cambio de la distribución ideológica. Para la construcción del modelo, se consideran los supuestos de voto ideológico simétrico y una sola dimensión. / This research project presents a spatial competition model for Venezuelan presidential elections based on the effective number of parties and weighted and scalar polarization indices. The model makes it possible to construct a classification of candidates’ influence based on personality as an remainder unexplained by spatial ideological competition.

Most important it was the Mexican revolution that it destroyed many of the oppressive structures under which was the immense majority of the population. The example of the movement invaded all Latin America and the notion of the agrarian reform was adopted by the advanced social sectors more than they tried to take to his own countries to more modern productive models. By the previous thing, the present study proposes to make an analytical reflection of the dynamics of change of the Venezuelan agrarian from an neoinstitutional perspective. It was concluded that the transformations in the Venezuelan agrarian structure sustain to a positive impact in their rural space and an opportunity for a reflective debate is opened on the paper of the institutions in the task of the Venezuelan agrarian question.El siglo XX arrancó en América Latina con intensos movimientos sociales. El más importante fue la revolución mexicana que destruyó muchas de las estructuras opresivas bajo las que se encontraba la inmensa mayoría de la población. El ejemplo del movimiento invadió toda América Latina y la noción de la reforma agraria fue adoptada por los sectores sociales más avanzados que intentaban llevar a sus propios países a modelos productivos más modernos. Por lo anterior, el presente estudio propone hacer una reflexión analítica de la dinámica agraria venezolana desde una perspectiva neoinstitucional. Se concluye que las transformaciones en la estructura agraria venezolana sustentan un impacto positivo en su espacio rural y abre la oportunidad para un debate reflexivo sobre el papel de las instituciones en el quehacer de la cuestión agraria venezolana.

    Full Text Available Las teorías monetarias modernas, ortodoxas y heterodoxas, han pasado por alto el hecho de que posterior a la Segunda Guerra Mundial el mundo quedó dividido entre economías emisoras y receptoras de reservas, pasando el sistema monetario internacional desde entonces a ser completamente asimétrico. De allí que, desde el punto de vista teórico, señalemos la necesidad de tomar en cuenta si las economías emiten o no una moneda de reserva internacional, pues ello explicaría la existencia de diversas prácticas monetarias a nivel mundial. Este trabajo propone, y calcula, indicadores basados en datos provenientes de los balances de activos y pasivos de quince bancos centrales pertenecientes a Norteamérica, Suramérica, Europa y Asia. Los hallazgos con respecto a las diversas estructuras de activos y pasivos confirman la hipótesis acerca de la presencia de tales asimetrías. Se infiere en consecuencia que la política monetaria es menos flexible pero más influyente en las economías receptoras de reservas, y a la vez más flexible pero menos influyente en las economías emisoras. En pocas palabras, la exogeneidad de la tasa de interés de corto plazo es más débil en el caso de las economías receptoras de reservas las cuales se ven obligadas a acumular divisas y a procurar la estabilidad del tipo de cambio, debido a que sus monedas locales no son aceptadas en el exterior. Así, aunque la oferta crediticia es endógena en esas economías, las mismas no han sido capaces de librarse aún de la necesidad de mantener reservas monetarias en divisas extranjeras

La población estuvo constituida por los Gerentes de Planificación e Imagen de las 10 corporaciones privadas venezolanas de mayor tamaño y cuatro expertos académicos en las áreas de Planificación e Imagen Corporativa. Como instrumentos de recolección de datos se utilizaron un cuestionario cerrado de 35 items para ser aplicado a los gerentes de las empresas y una entrevista abierta de 15 preguntas dirigida a los cuatro expertos académicos. Estos se sometieron a la validez de 10 expertos en el área de mercadeo, imagen corporativa, planificación estratégica y metodología. La confiabilidad del cuestionario fue de un coeficiente de 0,90. El estudio presenta las siguientes conclusiones en función de los resultados obtenidos en la investigación. Los procesos de formulación estratégica de las corporaciones privadas líderes venezolanas están caracterizados por el uso mayoritario de la Planificación Estratégica como herramienta para definir lineamientos estratégicos y guías para la acción en su gestión. En relación a su vinculación con el Análisis de Grupos de Interés, los procesos de Imagen Corporativa son vistos, por los expertos, como el elemento interfase entre los Grupos de Interés y la estrategia global de la corporación.

    Full Text Available La contabilidad de gestión ambiental ha sido considerada como una herramienta que permite presentar información referente al impacto que genera el desarrollo de la actividad económica empresarial en el medioambiente, conjuntamente con una evaluación de los beneficios económicos y el cumplimiento de las leyes establecidas para tal fin. En este sentido, la investigación tuvo como objetivo analizar la contabilidad de gestión ambiental en las empresas constructoras, como elemento estratégico promovido por el cumplimiento de la legislación venezolana. Metodológicamente, el tipo de investigación fue descriptiva, de campo, con diseño no experimental, transeccional. La población estuvo conformada por 15 contadores públicos que laboran en las empresas constructoras inscritas en la Asociación de Comerciantes e Industriales de Valera (acoinva, en el Estado Trujillo, Venezuela. La técnica de recolección de datos fue un cuestionario constituido por respuestas tipo escala Likert, e ítems de respuestas de alternativas supuestas según la teoría. Para la validez se utilizó el juicio de cinco expertos. A modo de conclusión, las empresas cumplen con los lineamientos establecidos por la legislación venezolana y, en función de ello, realizan planificación de su gestión ambiental para aprovechar los incentivos fiscales existentes, lo que ha generado en estas empresas la necesidad de utilizar registros contables que contribuyan con la clasificación de los datos financieros generados por los programas de mantenimiento y conservación del ecosistema.

    Full Text Available En este artículo se utiliza un procedimiento en dos fases para estimar la eficiencia en costos de la banca en Colombia y explorar sus determinantes potenciales durante el período 1999- 2007. La eficiencia en costos y sus componentes se calcula en la primera fase mediante la técnica no paramétrica conocida como DEA (Data Envelopment Analysis. En la segunda fase se utiliza una regresión Tobit para examinar la influencia del entorno y de algunas características específicas de cada agente sobre la eficiencia. Los resultados DEA indican niveles de ineficiencia en costos no significativamente diferentes de los parámetros internacionales, la cual, tal como lo señala la literatura empírica, es atribuible a la ineficiencia alocativa. Los resultados econométricos indican que el nivel de eficiencia observado fue influido significativamente por la concentración del mercado, el grado de profundización financiera, la relación de intermediación y el crecimiento económico. En cuanto a las variables específicas, sólo el grado de especialización influyó significativamente en los niveles de eficiencia observados.

    Full Text Available This pilot study examines the most relevant kinetic and kinematics variables in two bench press exercises; Smith Machine (PMS vs. free weights (PBL. Two trained subjects participated in the research following informed consent. To determine the maximum load (1-RM, two incremental protocols were used for PMS and PBL. Subject 1 (S-1 produced force values of 770N and 837N, peak force of 28ms and 12ms, in PBL and PMS respectively. Values for subject 2 (S-2 were 693N and 849N, PMF of 60ms and 66ms for PBL and PMS respectively. Detailed analyses of the following variables were performed; velocity curves for each load, the “sticking period”, the distances of grip width, and changes in bar inclination during the ascent phase of the lift were examined. The key findings of this research, and the basis for future research demonstrate that PBL is recommended as a training exercise, while more reliable information regarding force variables can be attained through using PMS in measurement sessions. Key Words: Bench Press, smith machine, free weight, strength assessment, upper limb.

    Emmanuel Borgucci

    2000-01-01

    Full Text Available En el siguiente artículo, se analiza cómo, desde el punto de vista político y económico, la autonomía que confería a los estados la Constitución de 1864 fue dando paso a una serie de revoluciones y cambios constitucionales que dieron al Ejecutivo Nacional (Ejecutivo Federal un número creciente de facultades que hicieron de Caracas el epicentro no solamente de la vida política sino económica de Venezuela. Haciendo uso de los planteamientos de North y Thomas, se demuestra que el marco institucional centralizado surgido desde 1870 contribuye a sentar las bases de la centralización política y económica de Venezuela. Se concluye, que la asignación por vía constitucional de menos poderes a los estados en Venezuela facilitó la incorporación de la economía zuliana a la venezolana desde el punto de vista de la Política Fiscal y Monetaria entre 1870 a 1908.

    Full Text Available La Ley de Okun es una relación estadística que plantea una correspondencia negativa entre cambios en la tasa de desempleo y cambios porcentuales en el producto real. En los últimos años el producto interno bruto real de Venezuela ha experimentado variaciones significativas, a la par que los datos revelan una disminución progresiva en la tasa de desempleo. Bajo este contexto se plantea el objetivo de este trabajo, estimar la Ley de Okun para la economía venezolana durante el período 1999-2009, con datos trimestrales, y en base a la evidencia empírica disponible. Este artículo plantea varias ecuaciones lineales para estimar los parámetros que relacionan los cambios en la tasa de desempleo ante cambios porcentuales en el producto, siguiendo la propuesta original de Arthur Okun. Las ecuaciones son estimadas por medio del método de Mínimos Cuadrados Ordinarios (MCO. Se encuentra evidencia, para el período de estudio, de una relación inversa entre ambas variables tal como lo plantea la teoría, más no obstante los coeficientes encontrados son bajos, lo que podría sugerir que la dinámica del desempleo en Venezuela se encuentra condicionada por factores adicionales a las fluctuaciones del producto

    Full Text Available La crisis socioambiental es actualmente uno de los temas más polémicos en el mundo, ante esta situación ha sido planteado en diferentes eventos internacionales el Desarrollo Sustentable (OS como un horizonte de posible solución. Con el objetivo de indagar la relación existente entre la investigación científica en las universidades autónomas venezolanas y el OS se realizó una investigación de carácter exploratoria-descriptiva, en la que se hizo uso intensivo y extensivo de la base de datos del Programa de Promoción al Investigador. Obteniéndose que las ciencias de la naturaleza son las de mayor representación, contradictoriamente a la ausencia de otras áreas prioritarias de conocimientos, tales como educación para la sostenibilidad, cambio climático, tecnología para la sostenibilidad, producción y consumo responsable, entre otros. Se concluye que, aún cuando se realiza investigación relacionada con el OS, es necesario fortalecer y explorar nuevas áreas relacionadas a lo social, técnico y económico, para lo cual se requiere de esfuerzos transdiciplinarios e interinstitucionales

Se seleccionaron siete de las diez emisoras universitarias que existen en el país. Se aplican para la evaluación técnicas provenientes del análisis de políticas públicas y gerenciales vinculadas con la teoría de los recursos y capacidades y con la generación de ventajas competitivas. Los resultados revelan que del total de universidades estudiadas, 6 (100%, sólo 2 (33% (Zulia y los Andes, poseen políticas comunicacionales explícitas. Las universidades que no tienen políticas comunicacionales explícitas se rigen por otros mecanismos explícitos o no. La política universitaria de comunicación no articula la misión y visión de las universidades con el funcionamiento de sus emisoras de radio. La generación de ventajas competitivas en las emisoras, obedece más a su gestión interna que a la preocupación de las universidades por hacer realmente efectiva la formulación e implementación de la política como tal.

La muestra de estudio la conformaron estudiantes de posgrado en gerencia de una universidad pública venezolana, y estaba compuesta por profesionales de ambos sexos provenientes de distintas profesiones (N = 162; media edad = 31,37; D.T. = 4,67. Se utilizaron diversos instrumentos como el Test de Definición de Criterios Morales (DIT, el Índice de Reactividad Interpersonal (IRI, la Subescala de Comprensión Empática, entre otros. Los resultados muestran que el modelo de rutas propuesto resultó parcialmente válido, evidenciando que la comprensión de las relaciones entre las variables del modelo resulta más compleja de lo que se plantea en la literatura; en tal sentido, la empatía es la variable más influyente en el modelo, al hallarse efectos directos altos y significativos sobre el desarrollo moral posconvencional y la capacidad de autoconocimiento y autocontrol emocional.

  14. Já nas bancas. Mediação e economia política da distribuição dos meios impressos

    Viktor Chagas

    2014-04-01

    Full Text Available A expressão “já nas bancas”, no Brasil, tornou-se sinônimo de presteza e agilidade. A frase é tomada como divisa em quaisquer peças publicitárias e de merchandising da imprensa, propagando por diferentes camadas sociais a imagem da banca como extensão do sistema de imprensa. O exemplo evidencia o tratamento legado a operações de distribuição no circuito cultural, geralmente estranguladas em favor do processo produtivo e de consumo. Neste artigo, pretendo discutir a perspectiva historiográfica das teorias sociais da imprensa acerca das etapas de circulação e distribuição dos meios impressos. Minha hipótese é de que são os vendedores e distribuidores de jornais e revistas agentes de fundamental importância cultural e política para o processual jornalístico das grandes cidades, e, no entanto, seu papel na cadeia produtiva dos periódicos impressos tem sido subjugado ante a análises que se concentram nas técnicas ou no discurso jornalístico, quando muito nas cercanias dos estudos de recepção e na apropriação da cultura popular – jamais na investigação sobre esta instituição que silenciosamente tem ocupado nosso imaginário por todos esses anos: as bancas de jornais e revistas.Dessa forma, procuramos compreender o papel dos vendedores e distribuidores de imprensa como mediadores no interior de outro processo de mediação, o jornalístico. Assim fazendo, buscamos refletir criticamente sobre o espaço legado a esta problemática sob três diferentes abordagens, o olhar acadêmico, o viés jurídico-institucional e, por fim, a perspectiva econômica. Em todos os casos, a banca opera como via de escoamento para a produção jornalística da imprensa escrita, geralmente articulando o discurso à experiência de consumo, e eventualmente sofrendo pressões políticas similares às dos próprios jornalistas. Ainda assim, sua participação neste circuito, em grande medida, passa desapercebida aos olhos leigos

Se diseñó una investigación de campo, descriptiva, con enfoque cualitativo, utilizándose la técnica de entrevista no estructurada. Los resultados muestran que, como vías para el desarrollo, los gerentes de las PyME sugieren el compromiso de la alta gerencia, implementación de políticas globales en materia de salud, educación y seguridad social; sí como políticas específicas que guíen las acciones para hacer realidad el futuro deseado. Lograrlo implica esfuerzos enmarcados en una estrategia industrial integral de desarrollo efectivo y coherente que propicie la formulación de respuestas globales para fortalecer las PyME y ayudarla a transitar hacia el nuevo paradigma con una competitividad profunda y duradera apuntalada en el concepto de responsabilidad social empresarial. Se concluye que son pilares para el desarrollo de las PyME: el apoyo del Estado para eliminar los desequilibrios existentes; la organización interna para incrementar efectividad y desempeño; la consolidación de una cultura de apoyo al mejoramiento organizacional y humano propiciadora de armonía al desempeñar las labores en condiciones de máximo bienestar y productividad.

Esas necesidades han cobrado protagonismo con la actual crisis financiera, económica y social, en la que se aprecia un deterioro de los valores elementales y, en consecuencia, una extensión del descrédito de las entidades bancarias. En esta situación, se revaloriza el papel del crédito cooperativo y de la “banca social”, instrumentos que, por sus especiales características, se han visto menos afectadas por la pérdida de reputación y se abren paso como alternativas. / Between the credit cooperatives origin and new social banking have passed by a century, in which banking systems have going through an extraordinary change. Despite their differences, both kinds of companies come up by similar reasons: Financial exclusion of vulnerable collectives and need of ethical, responsible and solidary responses. These needs have gain prominence in the present social and financial-economic crisis, in which a basic values deterioration and accordingly a growing essential values deterioration. In this situation increase the social banking and cooperative credit role. These tools have been less affected by loos of reputation because of their especial features and breaking through as new credit ways.

    Full Text Available This article makes a comparative analysis of the experiences of the independent central bank in Latin America and Europe. After reviewing the problems and theories of central bank autonomy, it studies the recent evolution of the Latin American central bank in comparison with the European central bank, high lights the perverse effects of the reforms, and shows that their objective is more the stability of the financial system than the stability of prices. Finally, it describes the tests to which the new Latin American central banks have been subjected and the effects on their credibility. It concludes that these entities have had to correct and pay for the incoherences and errors of the market, and that their independence or autonomy depends on their continuing to ful fill this role, not only for economíc or monetary reasons but for the needs of political and social democracy.Este artículo hace un análisis comparativo de las experiencias de la banca central independiente en América Latina y Europa.

    Full Text Available En los últimos años, las instituciones financieras venezolanas han pasado por varias etapas, tratando de adaptarse a los cambios de la economía nacional. Inicialmente, pasaron de ser empresas financieras regionales a nacionales y luego de especializadas a universales, sin embargo, estas estrategias no resultaron del todo, teniendo que buscar otras alternativas como las fusiones. La investigación se orientó a determinar el impacto que causan las fusiones bancarias en sus clientes externos, tomando como caso específico a la entidad financiera venezolana: Fondo Común Banco Universal, para lo cual se utilizó una metodología de carácter descriptivo y una combinación de estrategia documental y de campo. Se aplicó un muestreo no probabilístico de tipo intencional, seleccionando los elementos con base en criterios o juicios de los investigadores. De acuerdo a la opinión generalizada por los consultados, el nuevo banco es percibido por los clientes como una entidad menos ágil a la hora de prestar sus servicios.

Para ello se consideraron dos etapas, la primera correspondió a la evaluación de funcionalidades de los sitios Web bancarios, utilizando una adaptación del modelo de evaluación de sitios Web de Hersey, y la segunda a la evaluación de los servicios según las percepciones de los clientes. Para la determinación de las funcionalidades fue necesario detectar la presencia o ausencia de treinta y siete elementos evaluados, según lo cual fue posible clasificar al sector bancario chileno en términos de lo que ofrece o no cada institución. Por otra parte, la encuesta aplicada tanto a usuarios como no usuarios de la banca en línea permitió conocer variados factores referentes al uso y no uso de los servicios. A pesar de que existen algunos aspectos en los que la banca nacional se desempeña sólo de forma regular, en el contexto global lo hace con un alto grado de efectividad. Además, el buen desempeño en el contexto general se hace evidente al observar la gran equiparidad existente entre los resultados nacionales y los de la banca neocelandesaThe main objective of this study is to analyze the effectiveness of the services of Internet banking provided by thirteen Chilean banking institutions. To achieve this objective, two stages were considered. The first stage corresponded to the evaluation of the functionalities offered by the banking Web sites, using an adaptation of the Hersey Web site evaluation model. The second stage corresponded to the evaluation of the services according to the clients' perceptions.

    Horton, Sarah; Leventhal, Laura

    Universal usability of World Wide Web (Web) environments—that is, having 90% of households as successful users—requires universal access, usability, and universal design. Factors such as Web technology and user-centered design contribute to universal access and usability, but key to universal usability is a universal design methodology. Universal design principles for the Web follow from universal design principles for the built environment, and emphasize perceptibility, self-explanation, and tailorability for the user. Universally usable Web environments offer the benefit of expanded participation, as well as the unanticipated benefits that generally follow from innovative design initiatives. However, to achieve Web universal usability, Web designers need tools that facilitate the design of intuitive interfaces without sacrificing universal access.

The main arguments for the independence of a cen-tral bank are others: firstly, the opinion that governments are induced to in-cur excessive expenditure due to reasons highlighted by public choice theo-rists and, secondly, the idea that inflation arises in connection with social conflict. Additionally, this study makes it clear that 'time inconsistency' theory is far from being a new way of stating old ideas.  JEL Codes: E58Keywords:

    Full Text Available El artículo evalúa la intensidad de la competencia que enfrentan los bancos estatales en la captación de depósitos, en particular el Banco Nacional y el Banco de Costa Rica y, utiliza como metodología la determinación del valor de la elasticidad-interés por sus depósitos. La evidencia indica que los bancos estatales cuentan con un poder monopolístico en la captación de depósitos y, además, que ese poder se incrementó a partir de 1996, lo cual indica que estos bancos tienen un mercado cautivo de depósitos que es independiente de la tasa ofrecida por ellos y/o por sus competidores. Así, los bancos estatales pueden disminuir o aumentar las tasas de interés pagadas por sus depósitos y esto no tiene prácticamente ningún efecto sobre las cantidades de recursos financieros que los depositantes están dispuestos a llevarles, o, los competidores pueden elevar sus tasas muy por encima de las pagadas por estos bancos y no se producirá una reducción significativa de los depósitos de los bancos estatales.

    Universe Awareness (UNAWE) is an educational programme coordinated by Leiden University that uses the beauty and grandeur of the Universe to encourage young children, particularly those from an underprivileged background, to have an interest in science and technology and foster their sense of global citizenship from the earliest age.UNAWE's twofold vision uses our Universe to inspire and motivate very young children: the excitement of the Universe provides an exciting introduction to science and technology, while the vastness and beauty of the Universe helps broaden the mind and stimulate a sense of global citizenship and tolerance. UNAWE's goals are accomplished through four main activities: the coordination of a global network of more than 1000 astronomers, teachers and educators from more than 60 countries, development of educational resources, teacher training activities and evaluation of educational activities.Between 2011 and 2013, EU-UNAWE, the European branch of UNAWE, was funded by the European Commission to implement a project in 5 EU countries and South Africa. This project has been concluded successfully. Since then, the global project Universe Awareness has continued to grow with an expanding international network, new educational resources and teacher trainings and a planned International Workshop in collaboration with ESA in October 2015, among other activities.

No significant differences (P>0.05 were observed in number of repetitions, mean and maximal accelerative portion (AP, mean and maximal velocity, and lifting velocity time-course pattern. Males showed significantly higher values regarding number of repetitions achieved and maximal and mean lifting velocity. However, regarding the percentage of the concentric phase in which barbell is accelerated, there were no sex differences. In conclusion, no relevant difference in kinematics variables can be shown when applying any of these three different warm-up protocols, these results may be useful when designing training programs.

    In the past year, an increasing number of individual academic institutions have lobbied in Congress for new science facilities funds thus circumventing the traditional peer review process of evaluating the merits of such facilities. As an attempt to stem this rising tide, the National Academy of Sciences (NAS) governing council and the Association of American Universities (AAU) recently and independently issued strong statements condemning lobbying by individual universities and enthusiastically supporting the peer review system.“Informed peer judgments on the scientific merits of specific proposals, in open competition, should be a central element in the awarding of all federal funds for science,” the NAS resolution stated. AAU, meanwhile, implored “scientists, leaders of America's universities, and members of Congress” to “refrain from actions that would make scientific decisions a test of political influence rather than a judgment on the quality of the work to be done.” Roughly 50 research institutions constitute AAU; the two AAU Canadian members did not vote on the consortium's statement.

What is a human being? Objectively, nothing of consequence. Particles of dust in an infinite arena, present for an instant in eternity. Clumps of atoms in a universe with more galaxies than people. And yet a human being is necessary for the question itself to exist, and the presence of a question in the universe - any question - is the most wonderful thing. Questions require minds, and minds bring meaning. What is meaning? I don't know, except that the universe and every pointless speck inside it means something to me. I am astonished by the existence of a single atom, and find my civilisation to be an outrageous imprint on reality. I don't understand it. Nobody does, but it makes me smile. This book asks questions about our origins, our destiny, and our place i...

  2. Universal overgroup

    A way to separate irreducible unitary representations π for a Lie group G by moment sets is to use an infinite-dimensional overgroup G˜ and extensions of each representation π to a representation π˜ of G˜, in such a manner that the moment set of π˜ characterizes π. In this paper we propose a universal overgroup G˜, which is an infinite-dimensional Fréchet-Lie group. We extend each π to a Hamiltonian action π˜ of G˜. The moment set of π˜ characterizes π.

    Is Universal Grammar a universal grammar? From Chomsky's hierarchy we deduce that for each grammar there is a Turing machine, and conversely. Following this equivalence, it is immediate to conclude that a universal Turing machine is equivalent to a universal grammar. Meanwhile, in linguistics, Universal Grammar is the human brain circuitry that implements the faculty of language. So the definitive answer is achieved only when we show that the human brain is Turing complete, and that language ...

    Full Text Available Two propositions are discussed, the first to be attributed to the monetarists ("the variations of the monetary base determine those of prices", the second to certain Keynesian economists ("the variations of prices ultimately depend on the rate of unemployment". The author argues that both propositions are wrong. As for the former, it is maintained that inflationary impulses do not originate from the quantity of money but from the activity of firms, which, however, can be influenced by the policy of the central bank. As for the latter, the rate of unemployment appears to be only one of several vari-ables affecting the behaviour of wages and prices. A critical reappraisal of the explanation of inflation is now particularly important since the European Central Bank will become operative at the be-ginning of the next year.  JEL Codes: E31, E32Keywords:

Este estudio se desarrolló en la Unidad de Investigación de Análisis de Políticas Públicas y Desarrollo Socio-educativo de la Universidad de Carabobo. Tomando como referencias teóricas a E. Morin y J. Habermas, se desarrollan tres categorías presentes en la realidad de Venezuela: el Socialismo del Siglo XXI, el Estado Docente y la Autonomía Universitaria. El tratamiento metodológico parte del planteamiento de la premisa: el Nuevo Modelo de Educación Universitaria que está por construirse, se debe a la crisis del modelo cognitivo instrumental instituido en la Constitución de la República de Venezuela (1961, sus Leyes y Reglamentos. Al triangular las tres categorías se plantea, como valor agregado, concebir la educación a través de un proceso transdisciplinario, sustentado en una primera instancia por el ordenamiento jurídico que le dé concreción y sincronización en el tiempo y el movimiento. En el caso de la educación venezolana, se concluye que no se han producidos cambios significativos que nos indiquen que estamos en presencia de un nuevo modelo de educación. La educación universitaria sigue atada al modelo cognitivo instrumental, impidiendo cualquier cambio que desde su seno se pretenda impulsar, de manera que la nueva Ley de Educación Universitaria y el nuevo modelo de educación siguen diferido.Abstract: This essay is based on an analysis of the higher education in the context socio-political of the Venezuelan reality, in the reference period is 2007-2013, focused the promulgation of the organic law of education (2009.

John Gribbin navigates the latest frontiers of scientific discovery to tell us what we really know about the history of the universe. Along the way, he describes how the universe began; what the early universe looked like; how its structure developed; and what emerged to hold it all together. He describes where the elements came from; how stars and galaxies formed; and the story of how life emerged. He even looks to the future: is the history of the universe going to end with a Big Crunch or a Big Rip.

    People have always been fascinated with the stars above and the universe that contains them. Over the years, astronomers have developed numerous theories to explain how the universe began, how it works, and what its ultimate fate will be. But all of the scientists' questions are far from answered. The Expanding Universe goes beyond the creation of the universe to explain how scientists think the universe works, grows, and changes, including what great thinkers Isaac Newton and Albert Einstein had to say about its fate. Readers will also learn about how researchers are slowly shedding light on

    Universal grammar specifies the mechanism of language acquisition. It determines the range of grammatical hypothesis that children entertain during language learning and the procedure they use for evaluating input sentences. How universal grammar arose is a major challenge for evolutionary biology. We present a mathematical framework for the evolutionary dynamics of grammar learning. The central result is a coherence threshold, which specifies the condition for a universal grammar to induce coherent communication within a population. We study selection of grammars within the same universal grammar and competition between different universal grammars. We calculate the condition under which natural selection favors the emergence of rule-based, generative grammars that underlie complex language.

    Full Text Available This study is the result of an ethnographic research based on interpretative anthropology. It aims to interpret the meanings of alcohol misuse in families from a poor Venezuelan community. Twenty members from six families participated in the study. The results show differences between meanings children and parents held regarding alcohol consumption. Children held a more positive view, whereas mothers presented the lowest acceptation of alcohol consumption. Meanings were more convergent than divergent, which allowed the identification of the following units: excessive consumption, intoxication, and joy. The association of alcohol with parties and joy is the main motivation to drink and the main barrier to change drinking habits. Two units of meaning were identified: a continuum between normal and pathologic drinking; and concept of joy subordinated to alcohol consumption.Resultado de investigación etnográfica basada en la antropología interpretativa, este trabajo objetiva interpretar los significados del consumo de alcohol en familias de una comunidad pobre venezolana. Han sido investigadas seis familias, totalizando 20 participantes. Los resultados indican algunas distinciones entre padres, madres e hijos en la atribución de significados al consumo de alcohol, con una visión más valorativa en los hijos y menor aceptación entre las madres. Las convergencias de sentidos, más frecuentes que las diferencias, permitieron identificar las unidades de significación: el consumo excesivo, la borrachera, la alegría. En la asociación entre bebidas alcohólicas, alegría y fiesta está la principal motivación para beber y la principal fuente de resistencia a la modificación de conductas ante el alcohol. Los núcleos de significados identificados fueron: la existencia de un continuo entre el beber normal y patológico; una concepción de felicidad subordinada al consumo del alcohol.Resultado de pesquisa etnográfica, sob a ótica da antropologia

  5. Universities scale like cities.

    Directory of Open Access Journals (Sweden)

    Anthony F J van Raan

    Full Text Available Recent studies of urban scaling show that important socioeconomic city characteristics such as wealth and innovation capacity exhibit a nonlinear, particularly a power law scaling with population size. These nonlinear effects are common to all cities, with similar power law exponents. These findings mean that the larger the city, the more disproportionally they are places of wealth and innovation. Local properties of cities cause a deviation from the expected behavior as predicted by the power law scaling. In this paper we demonstrate that universities show a similar behavior as cities in the distribution of the 'gross university income' in terms of total number of citations over 'size' in terms of total number of publications. Moreover, the power law exponents for university scaling are comparable to those for urban scaling. We find that deviations from the expected behavior can indeed be explained by specific local properties of universities, particularly the field-specific composition of a university, and its quality in terms of field-normalized citation impact. By studying both the set of the 500 largest universities worldwide and a specific subset of these 500 universities--the top-100 European universities--we are also able to distinguish between properties of universities with as well as without selection of one specific local property, the quality of a university in terms of its average field-normalized citation impact. It also reveals an interesting observation concerning the working of a crucial property in networked systems, preferential attachment.

    In the last decades, renormalization group (RG) ideas have been applied to describe universal properties of different routes to chaos (quasi-periodic, period doubling or tripling, Siegel disc boundaries, etc). Each of the RG theories leads to universal scaling exponents which are related to the action of certain RG operators. The goal of this announcement is to show that there is a principle that organizes many of these scaling exponents. We give numerical evidence that the exponents of different routes to chaos satisfy approximately some arithmetic relations. These relations are determined by combinatorial properties of the route and become exact in an appropriate limit. (fast track communication)

    We show that in the isentropic scenario the first order thermodynamical particle creation model gives an emergent universe solution even when the chemical potential is non-zero. However there exists no emergent universe scenario in the second order non-equilibrium theory for the particle creation model. We then point out a correspondence between the particle creation model with barotropic equation of state and the equation of state giving rise to an emergent universe without particle creation in spatially flat FRW cosmology.

    Full Text Available Comentando la frase de Hegel de que “lo que hasta hoy se ha alcanzado en América es la expresión de una vida extranjera”, se dice que todo imperio intenta repetir en sus colonias el mundo y la vida de la metrópoli. Esta copia se traslada también a la educación. La universidad latinoamericana traída por los españoles pretendía ser una copia de las universidades de Salamanca o Alcalá. Los objetivos, los contenidos, los métodos pedagógicos –memorísticos y repetitivos- eran trasladados al pie de la letra al nuevo mundo que tenía poco que ver con el viejo mundo español. El esfuerzo por repetir lo extranjero produce una mentalidad colonial que se mantiene en la Universidad con el método actual, repetitivo y memorístico de la docencia. También el chauvinismo provinciano que niega todo valor a las ideas que llegan de fuera, es producto de esa mentalidad colonialista. La Universidad ideal será la que, sin dejar de discutir y analizar las ideas y verdades que nos llegan de afuera, crea y produce sus propias ideas y teorías. La que entra en diálogo con las ideas del mundo. Esto se alcanza sólo con la investigación.

    1991-01-01

    'There is evidence to suggest that our world and everything in it - from snowflakes to maple trees to falling stars and spinning electrons - are only ghostly images, projections from a level of reality literally beyond both space and time.' This is the astonishing idea behind the holographic theory of the universe, pioneered by two eminent thinkers: physicist David Bohm, a former protege of Albert Einstein, and quantum physicist Karl Pribram. The holographic theory of the universe encompasses consciousness and reality as we know them, but can also explain such hitherto unexplained phenomena as telepathy, out-of-body experiences and even miraculous healing. In this remarkable book, Michael Talbot reveals the extraordinary depth and power of the holographic theory of the universe, illustrating how it makes sense of the entire range of experiences within our universe - and in other universes beyond our own.

    The observed extragalactic background light (EBL) is affected by light attenuation due to absorption of light by galactic and intergalactic dust in the Universe. Even galactic opacity of 10-20 percent and minute universe intergalactic opacity of $0.01\\,\\mathrm{mag}\\,h\\,\\mathrm{Gpc}^{-1}$ at the local Universe have a significant impact on the EBL because obscuration of galaxies and density of intergalactic dust increase with redshift as $\\left(1+z\\right)^3$. Consequently, intergalactic opacity increases and the Universe becomes considerably opaque at $z > 3$. Adopting realistic values for galactic and intergalactic opacity, the estimates of the EBL for the expanding dusty universe are close to observations. The luminosity density evolution fits well measurements. The model reproduces a steep increase of the luminosity density at $z3.5$.

    In the public eye, universities are typically acknowledged for providing two kinds of services: education and research. But universities do much more—and with a long shelf life, too. Universities also promote classic virtues like to seize the day—carpe diem; dare to know—sapere aude; the value...... of hard work—semper ardens; and to hurry slowly with reflection—festina lente. Good old-fashioned Latin strong suits. The narrative of instilling these virtues is hardly ever advertised by academia. Why not? Partly because they sound almost archaic.

These dilemmas show us how incomplete our knowledge of gravity is, and how our concepts about the universe must at least be revised. Mainly, on the Wilkinson Microwave Anisotropy Probe (WMAP) fifth year, the data indicates that more than 90% of the total energy density of the universe is dark. Here we discuss the impact of these phenomena imprint on gravitational and quantum field theory's standard history. Moreover, we point out some recent and upcoming projects on Cosmology in a quest to understand theses issues thoroughly.

    2015-01-01

    The separate universe conjecture states that in General Relativity a density perturbation behaves locally (i.e. on scales much smaller than the wavelength of the mode) as a separate universe with different background density and curvature. We prove this conjecture for a spherical compensated tophat density perturbation of arbitrary amplitude and radius in $\\Lambda$CDM. We then use Conformal Fermi Coordinates to generalize this result to scalar perturbations of arbitrary configuration and scale in a general cosmology with a mixture of fluids, but to linear order in perturbations. In this case, the separate universe conjecture holds for the isotropic part of the perturbations. The anisotropic part on the other hand is exactly captured by a tidal field in the Newtonian form. We show that the separate universe picture is restricted to scales larger than the sound horizons of all fluid components. We then derive an expression for the locally measured matter bispectrum induced by a long-wavelength mode of arbitrary...

    The problems encountered in mixing industrial and university research goals can be major, but so can the benefits. The National Science Board (NSB) recently released a report on “University-Industry Research Relationships: Selected Studies” (U.S. Government Printing Office, Washington, DC, 1983). It is an analysis of the much-discussed new trend toward increased industrial funding of university research projects.University laboratories cannot generally solve industry's R&D problems. Success for the corporation in sponsoring academic research is realized in the value of cooperative research programs as training exercises for future industrial scientists. An occasional patent arising from such a project is considered an added benefit, not a primary goal.

    Einstein's static model is the first relativistic cosmological model. The model is static, finite and of spherical spatial symmetry. I use the solution of Einstein's field equations in a homogeneous and isotropic universe -- Friedmann's equation -- to calculate the radius of curvature of the model (also known as "Einstein's universe"). Furthermore, I show, using a Newtonian analogy, the model's mostly known feature, namely, its instability under small perturbations on the state of equilibrium.

  4. Determining All Universal Tilers

    A universal tiler is a convex polyhedron whose every cross-section tiles the plane. In this paper, we introduce a certain slight-rotating operation for cross-sections of pentahedra. Based on a selected initial cross-section and by applying the slight-rotating operation suitably, we prove that a convex polyhedron is a universal tiler if and only if it is a tetrahedron or a triangular prism.

    A famous problem in discrete geometry is to find all monohedral plane tilers, which is still open to the best of our knowledge. This paper concerns with one of its variants that to determine all convex polyhedra whose every cross-section tiles the plane. We call such polyhedra universal tilers. We obtain that a convex polyhedron is a universal tiler only if it is a tetrahedron or a pentahedron.

    We apply the qualitative theory of dynamical systems to the study of the Chaplygin gas cosmological model. In difference to earlier works devoted to this model we give up sign restrictions on the choice of the sign of the energy density and on the parameters characterising initial conditions for a cosmological evolution. It appears that exists a static stable open universe filled with the Chaplygin gas. Besides exist universes where the acoustic waves have a velocity exceeding that of light in the vacuum.

    The principal objectives of the Fossil Energy Program are to seek new ideas, new data, fundamental knowledge that will support the ongoing programs, and new processes to better utilize the nation's fossil energy resources with greater efficiency and environmental acceptability. Toward this end, the Department of Energy supports research projects conducted by universities and colleges to: Ensure a foundation for innovative technology through the use of the capabilities and talents in our academic institutions; provide an effective, two-way channel of communication between the Department of Energy and the academic community; and ensure that trained technical manpower is developed to carry out basic and applied research in support of DOE's mission. Fossil Energy's university activities emphasize the type of research that universities can do best - research to explore the potential of novel process concepts, develop innovative methods and materials for improving existing processes, and obtain fundamental information on the structure of coal and mechanisms of reactions of coal, shale oil, and other fossil energy sources. University programs are managed by different Fossil Energy technical groups; the individual projects are described in greater detail in this book. It is clear that a number of research areas related to the DOE Fossil Energy Program have been appropriate for university involvement, and that, with support from DOE, university scientific and technical expertise can be expected to continue to play a significant role in the advancement of fossil energy technology in the years to come.

    As part of the World Year of Physics, the Physics Section of the University of Geneva is organising a series of conferences for the uninitiated. Each of the conferences will begin with a demonstration in the auditorium of the detection of cosmic rays and, in collaboration with Professor E. Ellberger of the Conservatoire de Musique de Genève, of how these signals from the farthest reaches of the Universe can be used to create "cosmic music". The third conference in the series, "How to build a universe?", will take place on Tuesday 15 March 2005 and the speaker will be the CERN theoretical physicist, John Ellis. A tiny number of elementary particles are responsible for the very diverse universe that surrounds us. These basic building blocks of matter interact by exchanging photons and other similar particles. After summing up what we know about these fundamental building blocks, their role in the history of the universe will be discussed. Where does matter come from? Where do the structures that ...

    Using the known result that the nucleation of baby universes in correlated pairs is equivalent to spacetime squeezing, we show in this Letter that there exists a T-duality symmetry between two-dimensional warp drives, which are physically expressible as localized de Sitter little universes, and two-dimensional Tolman-Hawking and Gidding-Strominger baby universes respectively correlated in pairs, so that the creation of warp drives is also equivalent to spacetime squeezing. Perhaps more importantly, it has been also seen that the nucleation of warp drives entails a violation of the Bell's inequalities, and hence the phenomena of quantum entanglement, complementarity and wave function collapse. These results are generalized to the case of any dynamically accelerating universe filled with dark or phantom energy whose creation is also physically equivalent to spacetime squeezing and to the violation of the Bell's inequalities, so that the universe we are living in should be governed by essential sharp quantum theory laws and must be a quantum entangled system.

    Sheykhi, Ahmad; Wang, Bin

    2012-01-01

    We investigate the thermodynamical properties of the apparent horizon in a fractal universe. We find that one can always rewrite the Friedmann equation of the fractal universe in the form of the entropy balance relation $ \\delta Q=TdS+Td\\tilde{S}$, where $ \\delta Q $ and $ T $ are the energy flux and Unruh temperature seen by an accelerated observer just inside the apparent horizon, and $d\\tilde{S}$ is the entropy production term due to nonequilibrium thermodynamics of fractal universe. This shows that in a fractal universe, a treatment with nonequilibrium thermodynamics of spacetime may be needed. We also study the generalized second law of thermodynamics in the framework of fractal universe. When the temperature of the apparent horizon and the matter fields inside the horizon are equal, i.e. $T=T_h$, the generalized second law of thermodynamics can be fulfilled provided the deceleration and the equation of state parameters ranges either as $-1 \\leq q < 0 $, $- 1 \\leq w < - 1/3$ or as $q<-1$, $w<...

    The last century has seen enormous progress in our understanding of the Universe. We know the life cycles of stars, the structure of galaxies, the remnants of the big bang, and have a general understanding of how the Universe evolved. We have come remarkably far using electromagnetic radiation as our tool for observing the Universe. However, gravity is the engine behind many of the processes in the Universe, and much of its action is dark. Opening a gravitational window on the Universe will let us go further than any alternative. Gravity has its own messenger: Gravitational waves, ripples in the fabric of spacetime. They travel essentially undisturbed and let us peer deep into the formation of the first seed black holes, exploring redshifts as large as z ~ 20, prior to the epoch of cosmic re-ionisation. Exquisite and unprecedented measurements of black hole masses and spins will make it possible to trace the history of black holes across all stages of galaxy evolution, and at the same time constrain any devia...

    We exploit the parallel between dynamical black holes and cosmological spacetimes to describe the evolution of Friedmann-Lemaître-Robertson-Walker universes from the point of view of an observer in terms of the dynamics of the apparent horizon. Using the Hayward-Kodama formalism of dynamical black holes, we clarify the role of the Clausius relation to derive the Friedmann equations for a Universe, in the spirit of Jacobson’s work on the thermodynamics of spacetime. We also show how dynamics at the horizon naturally leads to the quantum-mechanical process of Hawking radiation. We comment on the connection of this work with recent ideas to consider our observable Universe as a Bose-Einstein condensate and on the corresponding role of vacuum energy.

  19. Do closed universes recollapse?

    Tipler, Frank J.

    The conditions for recollapse in universes with compact maximal hypersurfaces are investigated theoretically, reviewing the results of recent investigations. The importance of recollapse for observational astrophysics is briefly discussed, and particular attention is given to the implications of maximal hypersurfaces and to recollapse in S3 Friedmann universes. It is conjectured that all globally hyperbolic C2 maximally extended spatially homogeneous closed universes with S3 or S2 x S1 topology and with stress-energy tensors obeying the strong-energy, positive-pressure, dominant-energy, and matter-regularity conditions do expand from an all-encompassing initial singularity to a maximal hypersurface and then recollapse to an all-encompassing final singularity.

    Full Text Available The question of identifying the properties of language that are specific human linguistic abilities, i.e. Universal Grammar, lies at the center of linguistic research. This paper argues for a largely Emergent Grammar in phonology, taking as the starting point that memory, categorization, attention to frequency, and the creation of symbolic systems are all nonlinguistic characteristics of the human mind. The articulation patterns of American English rhotics illustrate categorization and systems; the distribution of vowels in Bantu vowel harmony uses frequencies of particular sequences to argue against Universal Grammar and in favor of Emergent Grammar; prefix allomorphy in Esimbi illustrates the Emergent symbolic system integrating phonological and morphological generalizations. The Esimbi case has been treated as an example of phonological opacity in a Universal Grammar account; the Emergent analysis resolves the pattern without opacity concerns.

    Full Text Available University autonomy represented an additional argument against government interference in university education. From academic perspective, the diversification of funding sources and the introduction of changes in the funding mechanism represented positive factors in the evolution of higher education. It is obvious that most of the problems associated with underfunding of higher education are relevant because it affects the quality of education and overall performance of universities. Since the training costs per capita in the higher education system were the lowest compared with the same indicator in relation to vocational schools and colleges in the period of 2005 – 2009, it is clear that underfunding is real and requires necessary measures to be taken to remedy the situation

    We introduce "anamorphic" cosmology, an approach for explaining the smoothness and flatness of the universe on large scales and the generation of a nearly scale-invariant spectrum of adiabatic density perturbations. The defining feature is a smoothing phase that acts like a contracting universe based on some Weyl frame-invariant criteria and an expanding universe based on other frame-invariant criteria. An advantage of the contracting aspects is that it is possible to avoid the multiverse and measure problems that arise in inflationary models. Unlike ekpyrotic models, anamorphic models can be constructed using only a single field and can generate a nearly scale-invariant spectrum of tensor perturbations. Anamorphic models also differ from pre-big bang and matter bounce models that do not explain the smoothness. We present some examples of cosmological models that incorporate an anamorphic smoothing phase.

Our argument is as follows: the world...

  8. Parallel universes beguile science

    CERN Multimedia

    2007-01-01

    A staple of mind-bending science fiction, the possibility of multiple universes has long intrigued hard-nosed physicists, mathematicians and cosmologists too. We may not be able -- as least not yet -- to prove they exist, many serious scientists say, but there are plenty of reasons to think that parallel dimensions are more than figments of eggheaded imagination.

  10. The Artful Universe Expanded

    Barrow, John D.

    2005-07-01

    Our love of art, writes John Barrow, is the end product of millions of years of evolution. How we react to a beautiful painting or symphony draws upon instincts laid down long before humans existed. Now, in this enhanced edition of the highly popular The Artful Universe , Barrow further explores the close ties between our aesthetic appreciation and the basic nature of the Universe. Barrow argues that the laws of the Universe have imprinted themselves upon our thoughts and actions in subtle and unexpected ways. Why do we like certain types of art or music? What games and puzzles do we find challenging? Why do so many myths and legends have common elements? In this eclectic and entertaining survey, Barrow answers these questions and more as he explains how the landscape of the Universe has influenced the development of philosophy and mythology, and how millions of years of evolutionary history have fashioned our attraction to certain patterns of sound and color. Barrow casts the story of human creativity and thought in a fascinating light, considering such diverse topics as our instinct for language, the origins and uses of color in nature, why we divide time into intervals as we do, the sources of our appreciation of landscape painting, and whether computer-generated fractal art is really art. Drawing on a wide variety of examples, from the theological questions raised by St. Augustine and C.S. Lewis to the relationship between the pure math of Pythagoras and the music of the Beatles, The Artful Universe Expanded covers new ground and enters a wide-ranging debate about the meaning and significance of the links between art and science.

  12. Geodesically Complete Universe

    Bars, Itzhak

    2011-01-01

    This talk is about solving cosmological equations analytically without approximations, and discovering new phenomena that could not be noticed with approximate solutions. We found all the solutions of the Friedmann equations for a specific model, including all the zero-size-bounce solutions that do not violate the null energy condition, as well as all the finite-size-bounce solutions, and then discovered model independent phenomena. Among them is the notion of geodesic completeness for the geometry of the universe. From this we learned a few new general lessons for cosmology. Among them is that anisotropy provides a model independent attractor mechanism to some specific initial values for cosmological fields, and that there is a period of antigravity in the history of the universe. The results are obtained only at the classical gravity level. Effects of quantum gravity or string theory are unknown, they are not even formulated, so there are new theoretical challenges.

  13. Universality for quintessence

    CERN Document Server

    Cicciarella, F

    2016-01-01

    Several recent works suggested the possibility of describing inflation by means of a renormalization group equation. In this paper we discuss the application of these methods to models of quintessence. In this framework a period of exponential expansion corresponds to the slow evolution of the scalar field in the neighborhood of a fixed point. A minimal set of universality classes for models of quintessence is defined and the transition from a matter dominated to quintessence dominated universe is studied. Models in which quintessence is non-minimally coupled with gravity are also discussed. We show that the formalism proves to be extremely convenient to describe quintessence and moreover we find that in most of the models discussed in this work quintessence naturally takes over ordinary matter.

    Kolb, Edward W; Tait, T M P; Kolb, Edward W.; Servant, Geraldine; Tait, Tim M. P.

    2003-01-01

    In a large class of extra-dimensional models, a scalar degree of freedom known as the radion is long-lived, or even stable, on cosmological scales. In this paper we investigate the impact of radionactivity on the evolution of the universe. We demonstrate that whether the radion overcloses the universe, constitutes the dark matter, is the inflaton, the curvaton, or does not play any role in cosmology, depends crucially on the ratio between the energy densities stored in the radion and in the inflaton at the time of inflation. We discuss the general difficulties reconciling models with low compactification scale (i.e., TeV scale) with the simple picture of inflation.

  15. The hot Hagedorn Universe

    Rafelski, Johann

    2016-01-01

    In the context of the half-centenary of Hagedorn temperature and the statistical bootstrap model (SBM) we present a short account of how these insights coincided with the establishment of the hot big-bang model (BBM) and helped resolve some of the early philosophical difficulties. We then turn attention to the present day context and show the dominance of strong interaction quark and gluon degrees of freedom in the early stage, helping to characterize the properties of the hot Universe. We focus attention on the current experimental insights about cosmic microwave background (CMB) temperature fluctuation, and develop a much improved understanding of the neutrino freeze-out, in this way paving the path to the opening of a direct connection of quark-gluon plasma (QGP) physics in the early Universe with the QCD-lattice, and the study of the properties of QGP formed in the laboratory.

  16. Improving University Research Value

    Kelley O’Reilly

    2012-07-01

    Full Text Available This article investigates the current data management practices of university researchers at an Intermountain West land-grant research university in the United States. Key findings suggest that researchers are primarily focused on the collection and housing of research data. However, additional research value exists within the other life cycle stages for research data—specifically in the stages of delivery and maintenance. These stages are where most new demands and requirements exist for data management plans and policies that are conditional for external grant funding; therefore, these findings expose a “gap” in current research practice. These findings should be of interest to academics and practitioners alike as findings highlight key management gaps in the life cycle of research data. This study also suggests a course of action for academic institutions to coalesce campus-wide assets to assist researchers in improving research value.

    Full Text Available In this work, first, I reexamine the pyrocentric universe of the Pythagorean, Philolaus, who emphatically propounded that the center of the cosmos is neither the earth nor the sun, but a central fiery hearth that stands in the middle of the spherical universe. Second, I attempt to demonstrate the value and significance of this pyrocentric cosmic model by elaborating its novel revolutionary elements and its contribution to astronomy. Third, by underlining the diachroneity and timeliness of this cosmic model, I try to establish as to how the model served as a precursor to not only the ancient and modern heliocentric models, as widely believed, but also as much to the contemporary cosmic models and theories of astrophysics.

  18. Universal metamaterial absorbe

    CERN Document Server

    Smaali, Rafik; Moreau, Antoine; Taliercio, Thierry; Centeno, Emmanuel

    2016-01-01

    We propose a design for an universal absorber, characterized by a resonance frequency that can be tuned from visible to microwave frequencies independently of the choice of the metal and the dielectrics involved. An almost resonant perfect absorption up to 99.8 % is demonstrated at resonance for all polarization states of light and for a very wide angular aperture. These properties originate from a magnetic Fabry-Perot mode that is confined in a dielectric spacer of $\\lambda/100$ thickness by a metamaterial layer and a mirror. An extraordinary large funneling through nano-slits explains how light can be trapped in the structure. Simple scaling laws can be used as a recipe to design ultra-thin perfect absorbers whatever the materials and the desired resonance wavelength, making our design truly universal.

    Ungerer, M J; le Roux, F P

    1978-02-25

    A true universal co-axial anaesthetic system has been designed. This system may be used either as a Mapleson A circuit during spontaneous ventilation or as a Mapleson D circuit during controlled ventilation. Conversion to either system may be conveniently carried out by interchanging the pop-off valve and fresh gas inlet, without disconnecting the system from the patient. Resistance to flow of both tubes has been measured and was found to be within acceptable limits. The efficiency of this system in a Mapleson A arrangement was compared with that of a conventional Magill circuit during spontaneous breathing in 2 conscious volunteers. It was shown that no significant difference exists between these systems eith regard to rebreathing, and that the universal co-axial system may be used as efficiently and economically as the Magill circuit during spontaneous ventilation. The co-axial system can be easily connected to a circle system, combining the advantages of the two systems.

    Pervushin, V N

    2014-01-01

    The present monograph is devoted to the theory of gravitation derived consequently as joint nonlinear realization of conformal and affine symmetries by means of Cartan differential forms. In the framework of the joint nonlinear realization of conformal and affine symmetries the interpretation of the last cosmological observational data of Ia Supernovae, anisotropy of the primordial radiation temperature and the mass spectrum of electroweak bosons, including the Higgs particle mass in the expected region ~ 125 GeV, is given. All these observational and experimental data testify to the vacuum energy dominance. The vacuum Casimir energy is a source of intensive cosmological quantum creation gravitons and electroweak bosons including Higgs particles from the empty Universe during the first 10^(-12) sec. The products of decay of the electroweak bosons give the matter content of the present day Universe, including primordial radiation and its baryon asymmetry.

    Full Text Available The article reports on the exploratory-descriptive investigation carried out to explain the writing behavior of the students of the Universidad Colegio Mayor of Cundinamarca. To this effect, it refers to the results of the project that are based on the state of the art of writing in higher education; it is supported by various conceptualizations about its technique throughout time, orality and writing at the University, the act of writing, and references about specific didactics. Furthermore, the article proposes theoretical approaches concerned with the process of writing, such as constructivism, meaningful learning, metacognition, social practices of language and new writing tendencies in information media. Through all this, the article present a profile of the University students on the level of writing and it evaluates their editing skills and the level of writing productiveness. This allows offering an academic proposal with possible guidelines for the institution to strengthen writing ability in their students.

  3. Gravity heats the Universe

    CERN Document Server

    Moss, Adam

    2009-01-01

    Structure in the Universe grew through gravitational instability from very smooth initial conditions. Energy conservation requires that the growing negative potential energy of these structures is balanced by an increase in kinetic energy. A fraction of this is converted into heat in the collisional gas of the intergalactic medium. Using a toy model of gravitational heating we attempt to link the growth of structure in the Universe and the average temperature of this gas. We find that the gas is rapidly heated from collapsing structures at around $z {\\sim} 10$, reaching a temperature ${>} 10^6$K today, depending on some assumptions of our simplified model. Before that there was a cold era from $z\\sim100$ to $\\sim10$ in which the matter temperature is below that of the Cosmic Microwave Background.

  7. Dark matter universe.

    Science.gov (United States)

    Bahcall, Neta A

    2015-10-06

    Most of the mass in the universe is in the form of dark matter--a new type of nonbaryonic particle not yet detected in the laboratory or in other detection experiments. The evidence for the existence of dark matter through its gravitational impact is clear in astronomical observations--from the early observations of the large motions of galaxies in clusters and the motions of stars and gas in galaxies, to observations of the large-scale structure in the universe, gravitational lensing, and the cosmic microwave background. The extensive data consistently show the dominance of dark matter and quantify its amount and distribution, assuming general relativity is valid. The data inform us that the dark matter is nonbaryonic, is "cold" (i.e., moves nonrelativistically in the early universe), and interacts only weakly with matter other than by gravity. The current Lambda cold dark matter cosmology--a simple (but strange) flat cold dark matter model dominated by a cosmological constant Lambda, with only six basic parameters (including the density of matter and of baryons, the initial mass fluctuations amplitude and its scale dependence, and the age of the universe and of the first stars)--fits remarkably well all the accumulated data. However, what is the dark matter? This is one of the most fundamental open questions in cosmology and particle physics. Its existence requires an extension of our current understanding of particle physics or otherwise point to a modification of gravity on cosmological scales. The exploration and ultimate detection of dark matter are led by experiments for direct and indirect detection of this yet mysterious particle.

    Using Planck scale oscillators in the background dark energy in a model that parallels the theory of phonons, we deduce the Planck mass, the elementary particle mass scale, the mass of the Universe and a recently discovered residual energy in the cosmic background. We also deduce the Beckenstein temperature formula for black holes. Finally we show that the model explains the four minute time lag in thearrival of gamma photons from a recently observed gamma flare by the MAGIC telescope.

  11. Inflation in the universe

    Energy Technology Data Exchange (ETDEWEB)

    Turner, M.S.

    1987-05-01

    The hot big bang cosmology, or the standard cosmology as it is appropriately known, is a highly successful model, providing a reliable and tested accounting of the Universe from 0.01 sec after the bang until today, some 15 Gyr later. However, very special initial data seem to be required in order to account for the observed smoothness and flatness of our Hubble volume and for the existence of the small primeval density inhomogeneities required for the formation of structure in the Universe. Inflation offers a means of accounting for these special initial data, which is based upon physics at sub-planck energy scales (<< m/sub pl/ approx. = 10/sup 19/ GeV) and is motivated by contemporary ideas in particle theory. Here I review the status of the 'Inflationary Paradigm'. At present essentially all inflationary models involve a very weakly-coupled (quantified by the presence of a dimensionless parameter of order 10/sup -12/ or so) scalar field which is displaced from the minimum of its potential. Regions of the Universe where the scalar field is initially displaced from its minimum undergo inflation as the scalar field relaxes, resulting in a Universe today which resembles ours in regions much larger than our present Hubble volume (approx. = 10/sup 28/ cm), but which on very large scales (>> 10/sup 28/ cm) may be highly irregular. The most conspicuous blemish on the paradigm is the lack of a compelling particle physics model to implement it. I also review some other unresolved issues, and discuss in detail the all important confrontation between inflation and observational data. Finally, I discuss the possibility that inflation leads to large-scale, primeval magnetic fields of sufficient strength to be of astrophysical interest. 123 refs., 4 figs.

  12. Universality and string theory

    Science.gov (United States)

    Bachlechner, Thomas Christian

    The first run at the Large Hadron Collider has deeply challenged conventional notions of naturalness, and CMB polarization experiments are about to open a new window to early universe cosmology. As a compelling candidate for the ultraviolet completion of the standard model, string theory provides a prime opportunity to study both early universe cosmology and particle physics. However, relating low energy observations to ultraviolet physics requires knowledge of the metastable states of string theory through the study of vacua. While it is difficult to directly obtain infrared data from explicit string theory constructions, string theory imposes constraints on low energy physics. The study of ensembles of low energy theories consistent with ultra-violet constraints provides insight on generic features we might expect to occur in string compactifications. In this thesis we present a statistical treatment of vacuum stability and vacuum properties in the context of random supergravity theories motivated by string theory. Early universe cosmology provides another avenue to high energy physics. From the low energy perspective large field inflation is typically considered highly unnatural: the scale relevant for the diameter of flat regions in moduli space is sub-Planckian in regions of perturbative control. To approach this problem, we consider generic Calabi-Yau compactifications of string theory and find that super-Planckian diameters of axion fundamental domains in fact arise generically. We further demonstrate that such super-Planckian flat regions are plausibly consistent with theWeak Gravity Conjecture.

    Full Text Available This study aims at determining the skills of Graphics Department students of Fine Arts Faculties with regards evaluating the emblembs of universities. The study follows a general survey model and the research group consists of the seniors studying at Graphics Departments of Fine Arts Faculties of Anadolu, Başkent, Dumlupınar, Hacettepe, Marmara and Süleyman Demirel Universities. In the study, data regarding the evaluations and interpretations of students and experts about the university emblems were collected through qualitative methods of analysis. Content analysis was employed for analysing the qualitative data gathered through interviews. As a result of the study, it was observed that students had relevant knowledge regarding emblems and design principles, and they, while evaluating the emblems as a graphic product, were able to exhibit such cognitive skills as analysing, interpreting, explaining, noticing and correcting, were able to notice the problems and recommend ways of solution through criticizing, and that they were very approximate to the experts in their evaluations. Therefore, it could be asserted that the students receive a quality graphics education.

  14. Mechanics of universal horizons

    Berglund, Per; Mattingly, David

    2012-01-01

    Modified gravity models such as Ho\\v{r}ava-Lifshitz gravity or Einstein-{\\ae}ther theory violate local Lorentz invariance and therefore destroy the notion of a universal light cone. Despite this, in the infrared limit both models above possess static, spherically symmetric solutions with "universal horizons" - hypersurfaces that are causal boundaries between an interior region and asymptotic spatial infinity. In other words, there still exist black hole solutions. We construct a Smarr formula (the relationship between the total energy of the spacetime and the area of the horizon) for such a horizon in Einstein-{\\ae}ther theory. We further show that a slightly modified first law of black hole mechanics still holds with the relevant area now a cross-section of the universal horizon. We construct new analytic solutions for certain Einstein-{\\ae}ther Lagrangians and illustrate how our results work in these exact cases. Our results suggest that holography may be extended to these theories despite the very differen...

  15. CRISIS COMMUNICATION IN UNIVERSITIES

    2015-07-01

    Full Text Available Abstract Institutions should implement effective crisis communication strategies to manage their reputations in crisis situations. Thus, the negative perceptions that may occur because of crisis can be reduced and eliminated by continuously informing stakeholders. Therefore, various researches are needed in the area of crisis communication management. The aim of the study is to determine the types of crises that often occur in universities and evaluate the crisis communication efforts in higher education institutions. Crises and crisis communication efforts were evaluated within the framework of media reflections in this study. Content analysis was applied in the classification of crises and responses provided for crises. As a result, the types of crises in Turkish universities were determined as campus safety, actions, protests, loss of confidential information, loss of financial opportunities, loss of key managers and personnel, staff problems, increase of accidents, slander and gossip, unnecessary explanations, rumors, damage to organization and employee reputation, terrorism, workplace violence, corruption, fire and epidemic. It is seen that universities don’t make any communicational effort regarding campus safety, staff problems, increase of accidents, corruption or fire.

    Electrogustometry is a method for taste diagnosis and measurement. The EG-2 project is being developed in cooperation between Warsaw University of Technology and Military institute of Medicine in Warsaw. The device is an evolution of the recent universal electrogustometer EG-1 prototype. Due to considerations and experiences acquired during prototype usage, many enhancements have been incorporated into device. The aim was to create an easy-to-use, portable, battery powered device, enabled for fast measurements. Developed electrogustometer is using innovative, low-power microprocessor system, which control whole device. User interface is based on 5.7" graphical LCD (Liquid Crystal Display) and touchscreen. It can be directly operated by finger or with optional stylus. Dedicated GUI (Graphical User Interface) offers simple, predefined measurements and advance settings of signal parameters. It is also possible to store measurements results and patients data in an internal memory. User interface is multilanguage. Signals for patients examinations, supplied with bipolar electrode, are generated by an on-board circuit using DDS (Direct-Digital Synthesis) and DAC (Digital-to-Analog Converter). Electrogustometer is able to generate DC, sinus, triangle or rectangle signals with current amplitude from 0 to 500 pA and frequency form 0 to 500 Hz. Device is designed for manual and automeasurement modes. By using USB (Universal Serial Bus) port it is possible to retrieve data stored in internal memory and charging of built-in Li-lon battery as a source of power.

    Lu, Jun; Zhang, Zhuo; Mo, Juan

    2014-01-01

    The conception of universal combinatorial coding is proposed. Relations exist more or less in many coding methods. It means that a kind of universal coding method is objectively existent. It can be a bridge connecting many coding methods. Universal combinatorial coding is lossless and it is based on the combinatorics theory. The combinational and exhaustive property make it closely related with the existing code methods. Universal combinatorial coding does not depend on the probability statistic characteristic of information source, and it has the characteristics across three coding branches. It has analyzed the relationship between the universal combinatorial coding and the variety of coding method and has researched many applications technologies of this coding method. In addition, the efficiency of universal combinatorial coding is analyzed theoretically. The multicharacteristic and multiapplication of universal combinatorial coding are unique in the existing coding methods. Universal combinatorial coding has theoretical research and practical application value.

  4. Exploring the relationship between university internationalization and university autonomy

    DEFF Research Database (Denmark)

    Turcan, Romeo V.; Gullieva, Valeria

    This paper explores a research gap at the intersection of university internationalization and university autonomy. A process model of university internationalization is put forward whereby the process of university internationalization is mediated by university internationalization capacity...... and moderated by target country institutional autonomy and globalization; and entry modes, timing and pace, as well as product mix of internationalization define university’s internationalization pattern. A systematic review is conducted to identify empirical studies at this intersection. One of the questions...... this paper is addressing is whether there is a scope for international business theories in explaining university internationalization or in light of recent findings from successes and failures of university internationalization international business theories ought to be revised?...

  5. A Preposterous Universe

    Recent announcements that the Cosmic Microwave Background (CMB) - the faint remnant of the Big Bang - is polarized have caused a stir among cosmologists. Such polarization has long been predicted but could not be detected, until the recent DASI and WMAP detections. The polarization is a signature of the motion of the primordial seeds that led to the galaxies and large-scale structure of the Universe observed today. Earlier measurements of tiny temperature fluctuations in the CMB have been used to infer the sizes of the primordial seeds. The polarization signature should help to determine the fundamental parameters of cosmology and to explain how large-scale structure arose [Highwire abstract].

    A model is presented for the origin of the large scale structure of the universe and their Mass-Radius scaling law. The physics is conventional, orthodox, but it is used to fashion a highly unorthodox model of the origin of the galaxies, their groups, clusters, super-clusters, and great walls. The scaling law fits the observational results and the model offers new suggestions and predictions. These include a largest, a supreme, cosmic structure, and possible implications for the recently observed pressing cosmological anomalies.

    The cosmos is an awfully big place and there is no better guide to its vast expanse and fascinating nooks and crannies than John Barrow. A professor of mathematical sciences at Cambridge University, Barrow embodies that rare combination of highly polished writer and expert scientist. His deft touch brings together the disparate threads of human knowledge and weaves them into a tapestry as rich and interesting for the expert as it is for the layperson. The Artful Universe Expanded is an updated edition of this popular book first published in 1995. It explores the deeply profound manner in which natural law and the nature of the cosmos have moulded and shaped us, our cultures and the very form of our arts and music-a new type of 'cosmic' anthropology. The main themes Barrow chooses for revealing this new anthropology are the subjects of evolution, the size of things, the heavens and the nature of music. The book is a large, eclectic repository of knowledge often unavailable to the layperson, hidden in esoteric libraries around the world. It rivals The Da Vinci Code for entertainment value and insights, but this time it is Nature's code that is revealed. It is rare indeed to find common threads drawn through topics as diverse as The Beetles, Bach and Beethoven or between Jackson Pollock, the Aztecs, Kant, Picasso, Byzantine mosaics, uranium-235 and the helix nebula. Barrow unerringly binds them together, presenting them in a stimulating, conversational style that belies the amount of time that must have gone into researching this book. Dip into it at random, or read it from cover to cover, but do read it. The Artful Universe Expanded is an entertaining antidote to the oft-lamented pressures to know more and more about less and less and the apparently inexorable march of specialization. On reading this book one can, for a short time at least, hold in one's mind a vision that unifies science, art and culture and glimpse a universal tapestry of great

    We study universal uncertainty relations and present a method called joint probability distribution diagram to improve the majorization bounds constructed independently in [Phys. Rev. Lett. 111, 230401 (2013)] and [J. Phys. A. 46, 272002 (2013)]. The results give rise to state independent uncertainty relations satisfied by any nonnegative Schur-concave functions. On the other hand, a remarkable recent result of entropic uncertainty relation is the direct-sum majorization relation. In this paper, we illustrate our bounds by showing how they provide a complement to that in [Phys. Rev. A. 89, 052115 (2014)]. PMID:27775010

    2003-01-01

    By assuming certain analytic properties of the propagator, it is shown that universal features of the spectral function including threshold enhancement arise if a pole describing a particle at high temperature approaches in the complex energy plane the threshold position of its two-body decay with the variation of T. The case is considered, when one can disregard any other decay processes. The quality of the proposed description is demonstrated by comparing it with the detailed large N solution of the linear sigma model around the pole-threshold coincidence.

    Is meaningful communication possible between two intelligent parties who share no common language or background? In this work, a theoretical framework is proposed in which it is possible to address when and to what extent such semantic communication is possible: such problems can be rigorously addressed by explicitly focusing on the goals of the communication. Under this framework, it is possible to show that for many goals, communication without any common language or background is possible using universal protocols. This work should be accessible to anyone with an undergraduate-level knowled

    Recent measurements of over 1056 confirmed exoplanets reveal details about their masses, compositions, orbital parameters, possible evolutionary histories, and even their atmospheres. These results, though marking just the beginnings of a dramatic new period of exoplanet discovery, suggest that for all practical purposes we are alone in the universe, at least in the sense implied by SETI: extraterrestrial intelligence. This talk will summarize the evidence to date, offer conclusions about the critical importance of increased exoplanet research, and emphasize the need for a renewed appreciation of the rare value of the Earth, its fragile environment, and its inhabitants.

    This book presents a new approach to the subject of cosmology. It fully exploits Einstein's theory of general relativity. It is found that the most general formal expression of the theory replaces the (10-component) tensor formalism with a (16-component) quaternion formalism. This leads to a unified field theory, where one field incorporates gravitation and electromagnetism. The theory predicts an oscillating universe cosmology with a spiral configuration. Dark matter is explained in terms of a sea of particle-antiparticle pairs, each in a particular (derived) ground state. This leads to an ex

We apply the proposed methodology to extract from data the Higgs branching ratios, production cross sections, couplings and to analyse composite H...... as an alternative to the Higgs, and disfavour fits with negative Yukawa couplings. We derive for the first time the SM Higgs boson mass from the measured rates, rather than from the peak positions, obtaining M-h = 124.4 +/- 1.6 GeV....

  3. Models of the universe

    Science.gov (United States)

    Fischer, Arthur E.

    1996-01-01

    In this paper a theory of models of the universe is proposed. We refer to such models ascosmological models, where a cosmological model is defined as an Einstein-inextendible Einstein spacetime. A cosmological model isabsolute if it is a Lorentz-inextendible Einstein spacetime,predictive if it is globally hyperbolic, andnon-predictive if it is nonglobally-hyperbolic. We discuss several features of these models in the study of cosmology. As an example, any compact Einstein spacetime is always a non-predictive absolute cosmological model, whereas a noncompact complete Einstein spacetime is an absolute cosmological model which may be either predictive or non-predictive. We discuss the important role played by maximal Einstein spacetimes. In particular, we examine the possible proper Lorentz-extensions of such spacetimes, and show that a spatially compact maximal Einstein spacetime is exclusively either a predictive cosmological model or a proper sub-spacetime of a non-predictive cosmological model. Provided that the Strong Cosmic Censorship conjecture is true, a generic spatially compact maximal Einstein spacetime must be a predictive cosmological model. It isconjectured that the Strong Cosmic Censorship conjecture isnot true, and converting a vice to a virtue it is argued that the failure of the Strong Cosmic Censorship conjecture would point to what may be general relativity's greatest prediction of all, namely,that general relativity predicts that general relativity cannot predict the entire history of the universe.

    Over the past few decades, NASA missions have revealed that we live in a Universe that is not a hydrogen-dominated, physicist's paradise, but in a molecular Universe with complex molecules directly interwoven into its fabric. These missions have shown that molecules are an abundant and important component of astronomical objects at all stages of their evolution and that they play a key role in many processes that dominate the structure and evolution of galaxies. Closer to home in our galaxy, the Milky Way, they have revealed a unique and complex organic inventory of regions of star and planet formation that may well represent some of the prebiotic roots to life. Astrobiology emerges from the great interest in understanding astrochemical evolution from simple to complex molecules, especially those with biogenic potential and the roles they may play as primordial seeds in the origin of life on habitable worlds. The first part of this talk will highlight how infrared spectroscopic studies of interstellar space, combined with dedicated laboratory simulations, have revealed the widespread presence of complex organics across deep space. The remainder of the presentation will focus on the evolution of these materials and astrobiology.

  5. Universality of TMD correlators

    Directory of Open Access Journals (Sweden)

    Buffing M.G.A.

    2015-01-01

    Full Text Available In a high-energy scattering process with hadrons in the initial state, color is involved. Transverse momentum dependent distribution functions (TMDs describe the quark and gluon distributions in these hadrons in momentum space with the inclusion of transverse directions. Apart from the (anti-quarks and gluons that are involved in the hard scattering process, additional gluon emissions by the hadrons have to be taken into account as well, giving rise to Wilson lines or gauge links. The TMDs involved are sensitive to the process under consideration and hence potentially nonuniversal due to these Wilson line interactions with the hard process; different hard processes give rise to different Wilson line structures. We will show that in practice only a finite number of universal TMDs have to be considered, which come in different linear combinations depending on the hard process under consideration, ensuring a generalized universality. For quarks this gives rise to three Pretzelocity functions, whereas for gluons a richer structure of functions arises.

    We present our study on cosmic opacity, which relates to changes in photon number as photons travel from the source to the observer. Cosmic opacity may be caused by absorption or scattering due to matter in the Universe, or by extragalactic magnetic fields that can turn photons into unobserved particles (e.g., light axions, chameleons, gravitons, Kaluza-Klein modes), and it is crucial to correctly interpret astronomical photometric measurements like type Ia supernovae observations. On the other hand, the expansion rate at different epochs, i.e., the observational Hubble parameter data H (z ), are obtained from differential ageing of passively evolving galaxies or from baryon acoustic oscillations and thus are not affected by cosmic opacity. In this work, we first construct opacity-free luminosity distances from H (z ) determinations, taking into consideration correlations between different redshifts for our error analysis. Moreover, we let the light-curve fitting parameters, accounting for distance estimation in type Ia supernovae observations, free to ensure that our analysis is authentically cosmological-model independent and gives a robust result. Any nonzero residuals between these two kinds of luminosity distances can be deemed as an indication of the existence of cosmic opacity. While a transparent Universe is currently consistent with the data, our results show that strong constraints on opacity (and consequently on physical mechanisms that could cause it) can be obtained in a cosmological-model-independent fashion.

    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.

    Wardle, M; Wardle, Mark Walker & Mark

    1999-01-01

    Modelling of Extreme Scattering Events suggests that the Galaxy's dark matter is an undetected population of cold, AU-sized, planetary-mass gas clouds. None of the direct observational constraints on this picture -- thermal/non-thermal emission, extinction and lensing -- are problematic. The theoretical situation is less comfortable, but still satisfactory. Galactic clouds can survive in their current condition for billions of years, but we do not have a firm description for either their origin or their evolution to the present epoch. We hypothesise that the proto-clouds formed during the quark-hadron phase transition, thereby introducing the inhomogeneity necessary for compatibility with light element nucleosynthesis in a purely baryonic universe. We outline the prospects for directly detecting the inferred cloud population. The most promising signatures are cosmic-ray-induced H-alpha emission from clouds in the solar neighbourhood, optical flashes arising from cloud-cloud collisions, ultraviolet extinction,...

    2012-01-01

    We consider a Hubble expansion law modified in the infra-red by distance-dependent terms, and attempt to enforce homogeneity upon it. As a warm-up, we re-derive the basic kinematics of a Friedman Robertson Walker universe without using standard general relativistic tools: we describe the expansion with a `Hubble velocity field' rather than with a four dimensional metric. Then we extend this analysis to the modified Hubble expansion and impose a transformation for velocities that makes it identical for all comoving observers, and therefore homogeneous. We derive the modified equation for light ray trajectories and other geometrical properties that are incompatible with the general relativistic description. We speculate that this extended framework could help addressing cosmological problems which are normally explained with accelerating expansions.

    2005-01-01

    We investigate the point-parity and mirror-parity handedness of the large angle anisotropy in the cosmic microwave background (CMB). In particular we consider whether the observed low CMB quadrupole could more generally signal odd point-parity, i.e. suppression of even multipoles. Even though this feature is ``visually'' present in most renditions of the WMAP dataset we find that it never supports parity preference beyond the meagre 95% confidence level. This is fortunate as point parity handedness implies almost certainly a high level of galactic contamination. Mirror reflection parity, on the contrary, is related to the emergence of a preferred axis, defining the symmetry plane. We use this technique to make contact with recent claims for an anisotropic Universe, showing that the detected preferred axis is associated with positive (even) mirror parity. This feature may be an important clue in identifying the culprit for this unexpected signal.

    There are currently over 900 facilities in over 170 countries which fall under International Atomic Energy Agency (IAEA) safeguards. As additional nations look to purse civilian nuclear programs or to expand infrastructure already in place, the number of reactors and accompanying facilities as well as the quantity of material has greatly increased. Due to the breadth of the threat and the burden placed on the IAEA as nuclear applications expand, it has become increasingly important that safeguards professionals have a strong understanding of both the technical and political aspects of nonproliferation starting early in their career. To begin overcoming this challenge, Idaho National Laboratory, has partnered with local universities to deliver a graduate level nuclear engineering course that covers both aspects of the field with a focus on safeguards applications. To date over 60 students across multiple disciplines have participated in this course with many deciding to transition into a nonproliferation area of focus in both their academic and professional careers.

    2015-01-01

    Measuring the state of a quantum system is a fundamental process in quantum mechanics and plays an essential role in quantum information and quantum technologies. One method to measure a quantum observable is to sort the system in different spatial modes according to the measured value, followed by single-particle detectors on each mode. Examples of quantum sorters are polarizing beam-splitters (PBS) -- which direct photons according to their polarization -- and Stern-Gerlach devices. Here we propose a general scheme to sort a quantum system according to the value of any $d$-dimensional degree of freedom, such as spin, orbital angular momentum (OAM), wavelength etc. Our scheme is universal, works at single-particle level and has a theoretical efficiency of 100%. As an application we design an efficient OAM sorter consisting of a single multi-path interferometer which is suitable for a photonic chip implementation.

Historically speaking, human rights are closely connected with globalization, but at the same time, they raise a question about the foundation of globalization: is there a universal community or only economic and political power-relations? The article argues that the political use of human rights...... discourses is split down the middle: it serves both as a critique of power and as an extension of power, and the disclosure of this split helps us understand the inner politics of human rights.

There are even fewer visualization toolkits and frameworks from which one can develop ones own visualization applications. Even within the research community, scientists either use what they can from the available tools or start from scratch to define a program in which they are able to develop new or modified visualization techniques and analysis algorithms. Presented here is a new general-purpose platform for constructing numerous visualization and analysis applications. The focus of this system is the design and experimentation of new techniques, and where the sharing of and integration with other tools becomes second nature. Moreover, this platform supports multiple large data sets, and the recording and visualizing of user sessions. Here we introduce the Universal Visualization Platform (UVP) as a modern data visualization and analysis system.

  20. Universal Limit on Communication

    CERN Document Server

    Bousso, Raphael

    2016-01-01

    I derive a universal upper bound on the capacity of any communication channel between two distant systems. The Holevo quantity, and hence the mutual information, is at most of order $E \\Delta t / \\hbar$, where $E$ the average energy of the signal, and $\\Delta t$ is the amount of time for which detectors operate. The bound does not depend on the size or mass of the emitting and receiving systems, nor on the nature of the signal. No restrictions on preparing and processing the signal are imposed. As an example, I consider the encoding of information in the transverse or angular position of a signal emitted and received by systems of arbitrarily large cross-section. In the limit of a large message space, quantum effects become important even if individual signals are classical, and the bound is upheld.

    The evolution of human languages is driven both by primitive biases present in the human sensorimotor systems and by cultural transmission among speakers. However, whether the design of the language faculty is further shaped by linguistic biological biases remains controversial. To address this question, we used near-infrared spectroscopy to examine whether the brain activity of neonates is sensitive to a putatively universal phonological constraint. Across languages, syllables like blif are preferred to both lbif and bdif. Newborn infants (2-5 d old) listening to these three types of syllables displayed distinct hemodynamic responses in temporal-perisylvian areas of their left hemisphere. Moreover, the oxyhemoglobin concentration changes elicited by a syllable type mirrored both the degree of its preference across languages and behavioral linguistic preferences documented experimentally in adulthood. These findings suggest that humans possess early, experience-independent, linguistic biases concerning syllable structure that shape language perception and acquisition.

    The idea that space is not Euclidean by necessity, and that there are other kinds of "curved" spaces, diffused slowly to the physical and astronomical sciences. Until Einstein's general theory of relativity, only a handful of astronomers contemplated a connection between non-Euclidean geometry and real space. One of them, the German astrophysicist Johann Carl Friedrich Zöllner (1834-1882), suggested in 1872 a remarkable cosmological model describing a finite universe in closed space. I examine Zöllner's little-known contribution to cosmology and also his even more unorthodox speculations of a four-dimensional space including both physical and spiritual phenomena. I provide an overview of Zöllner's scientific work, of his status in the German scientific community, and of the controversies caused by his polemical style of science. Zöllner's cosmology was effectively forgotten, but there is no reason why it should remain an unwritten chapter in the history of science.

    An alien invasion of CERN? Is there life elsewhere in the Universe? Are we alone? These questions have always fascinated humanity and for more than 30 years, physicists, biologists, chemists, cosmologists and astronomers have worked tirelessly to answer these questions. Yet just this past week at CERN students from all over Europe came to present their ideas on the subject and listen to the latest on extraterrestrial life from some of the world's most prestigious researchers. Students participating in the programme were encouraged to present their views on extraterrestrial life creatively and boy did they! The team from Portugal ran performances of Greek Theatre, the team from Hungary created a board game, while the team from Belgium recited poetry questioning the existence of extraterrestrials. But all was not light hearted, there were touching presentations of violin and piano by the French team and a very thought provoking theatre performance by the German team contrasting the search for extraterrestrial...

    The Virtual Hybridization approach predicts the most probable hybridization sites across a target nucleic acid of known sequence, including both perfect and mismatched pairings. Potential hybridization sites, having a user-defined minimum number of bases that are paired with the oligonucleotide probe, are first identified. Then free energy values are evaluated for each potential hybridization site, and if it has a calculated free energy of equal or higher negative value than a user-defined free energy cut-off value, it is considered as a site of high probability of hybridization. The Universal Fingerprinting Chip Applications Server contains the software for visualizing predicted hybridization patterns, which yields a simulated hybridization fingerprint that can be compared with experimentally derived fingerprints or with a virtual fingerprint arising from a different sample.

    2005-08-01

    Fred Hoyle was a Yorkshire truant who became the voice of British astronomy. For fifty years, he spoke out for astronomy in the newspapers, on government committees, at scientific meetings, in popular books and on the radio. He devised a never-ending history of the universe, and worked out how the elements were made. He founded a prestigious institute for theoretical astronomy and built a giant telescope, and if it rained on his summer holiday, he sat in his caravan and wrote science fiction novels for his legions of fans around the world. Fred Hoyle also claimed that diseases fall from the sky, that the big bang never happened, and that the Astronomer Royal should be abolished. When the outspoken Fred Hoyle spoke out for astronomy, some astronomers really wished he had kept his mouth shut. This book tells the behind-the-scenes story of Hoyle's widely acclaimed and deeply controversial role in the ideas, organization and public face of astronomy in post-war Britain. It chronicles the triumphs, acrimony, jealousies, rewards and bitter feuds of a field in turmoil, and meets the astronomers, contemplating cosmic questions, keeping secrets, losing their tempers, winkling information out of distant stars and, over tea on the lawn, discussing the finer points of libel law. Fred Hoyle's Universe draws on previously confidential government documents, recently released personal correspondence and interviews with Hoyle's friends, colleagues and critics, as well as with Hoyle himself, to bring you the man, the science, and the scandal behind the genial and genteel facade of the most exciting period in the history of astronomy.

    Full Text Available According to Garcia Canclini (1990 there is the assumption that Colombia is a hybrid society. Upon this standpoint, and within a traditional higher education structure characterized by being fundamentally conventional or campus based, the Open University Center of the Pontificia Universidad Javeriana was created as an education program that breaks with every traditional scheme, which in turn, encourages a new learning pattern. The Open University Center emerges as a "social response" focused on the "here and now" of today's society in Colombia.The Javeriana University (a hybrid university can be placed in this context as well as the Open University Center, as a part of it. Since its creation, through its programs this center offers education to the most vulnerable of Colombia's population, contributing to raise their quality of life.In this article, the authors outline the Open University Center's place in the University's context: its historical development and its structure concerning students, programs, regulations, infrastructure and technological equipment. They also identify the implications and relationships of the traditional education proper of the Pontificia Universidad Javeriana, as well as the projection and contributions of the Open University Center to the University's future in the pedagogical order of distance education towards virtual education.

    Today many universities have the vision to become a research university, including in Indonesia. It is based on the desire to play a role in advancing science for the benefit of humanity as well as to enhance the university reputation at the international level. However, in the case of Indonesia, it can only be done by several universities, given the large number of universities with very different capabilities. In addition, another problem is human resources, infrastructure, and research funding. Various targets indicator used to determine its success include the number of publications, patents and industrial products. There is an urgent need to improve all factors that can accelerate the increase in research in Indonesia universities, and has been started by the policy of the current government.

    This book challenges traditional approach to university autonomy which is based on four pillars: organisational, financial, human resource, and academic. The main thesis is that a fuller understanding of university autonomy can only be obtained through a more holistic view of the complex inter......-relationships between stakeholders and policies which can reinforce and equally pull in opposite directions. The holistic view is expressed in a model of institutional university autonomy that brings together the traditional basic four pillars of autonomy, and five interfaces: government–university; university–university...... staff; academic staff–students; university–business; and university–internationalisation. This model is explored through international case studies that give new insights and reinforce our understanding that the issues relating to institutional university autonomy are complex, interactive and genuinely...

  10. A Small Universal Petri Net

    Full Text Available A universal deterministic inhibitor Petri net with 14 places, 29 transitions and 138 arcs was constructed via simulation of Neary and Woods' weakly universal Turing machine with 2 states and 4 symbols; the total time complexity is exponential in the running time of their weak machine. To simulate the blank words of the weakly universal Turing machine, a couple of dedicated transitions insert their codes when reaching edges of the working zone. To complete a chain of a given Petri net encoding to be executed by the universal Petri net, a translation of a bi-tag system into a Turing machine was constructed. The constructed Petri net is universal in the standard sense; a weaker form of universality for Petri nets was not introduced in this work.

  11. Is the Universe logotropic?

    Science.gov (United States)

    Chavanis, Pierre-Henri

    2015-07-01

    We consider the possibility that the universe is made of a single dark fluid described by a logotropic equation of state P = A ln( ρ/ρ*, where ρ is the rest-mass density, ρ * is a reference density, and A is the logotropic temperature. The energy density ɛ is the sum of two terms: a rest-mass energy term ρ c 2 that mimics dark matter and an internal energy term u( ρ) = - P( ρ) - A that mimics dark energy. This decomposition leads to a natural, and physical, unification of dark matter and dark energy, and elucidates their mysterious nature. In the early universe, the rest-mass energy dominates and the dark fluid behaves as pressureless dark matter ( P ≃ 0, ɛ ∝ a -3. In the late universe, the internal energy dominates and the dark fluid behaves as dark energy ( P ˜ - ɛ, ɛ ∝ ln a. The logotropic model depends on a single parameter B = A / ρ Λ c 2 (dimensionless logotropic temperature), where ρ Λ = 6.72 × 10-24 g m-3 is the cosmological density. For B = 0, we recover the ΛCDM model with a different justification. For B > 0, we can describe deviations from the ΛCDM model. Using cosmological constraints, we find that 0 ≤ B ≤ 0.09425. We consider the possibility that dark matter halos are described by the same logotropic equation of state. When B > 0, pressure gradients prevent gravitational collapse and provide halo density cores instead of cuspy density profiles, in agreement with the observations. The universal rotation curve of logotropic dark matter halos is consistent with the observational Burkert profile (Burkert, Astrophys. J. 447, L25 (1995)) up to the halo radius. It decreases as r -1 at large distances, similarly to the profile of dark matter halos close to the core radius (Burkert, arXiv:1501.06604). Interestingly, if we assume that all the dark matter halos have the same logotropic temperature B, we find that their surface density Σ 0 = ρ0 r h is constant. This result is in agreement with the observations (Donato et al., Mon

    The boundary conditions to be imposed on the quantum state of the whole multiverse could be such that the universes would be created in entangled pairs. Then, interuniversal entanglement would provide us with a vacuum energy for each single universe that might be fitted with observational data, making testable not only the multiverse proposal but also the boundary conditions of the multiverse. Furthermore, the second law of the entanglement thermodynamics would enhance the expansion of the single universes.

    We investigate the behaviour of exact closed bouncing Friedmann universes in theories with varying constants. We show that the simplest BSBM varying alpha theory leads to a bouncing universe. The value of alpha increases monotonically, remaining approximately constant during most of each cycle, but increasing significantly around each bounce. When dissipation is introduced we show that in each new cycle the universe expands for longer and to a larger size. We find a similar effect for closed bouncing universes in Brans-Dicke theory, where G also varies monotonically in time from cycle to cycle. Similar behaviour occurs also in varying speed of light theories.

    Full Text Available The dramatic expansion of Taiwan universities/colleges from about 100 to 160 from the late 1980s has encountered problems due to social and global changes. What should Taiwan universities move toward and how? This research relies on secondary data to explore the issues Taiwan universities currently face—a low birth rate and global competition. The decreasing number of incoming students will result in a lower registration rate and less tuition revenue, which will make some universities struggle to survive. Hence, government policies, proposed by the Ministry of Education, have been implemented to assist Taiwan universities to adjust to external changes. The Innovative Transformation Policy, adopted in 2015, consists of strategies for university–industry cooperation, university mergers, university closures, and a re-shaping of the university paradigm. This policy has begun to be implemented and its initial outcome will be continually evaluated. In accordance with the Innovative Transformation Policy, this study encourages Taiwan universities to improve governance, set prominent unique characteristics of development, and enhance global competitiveness.

    The philosophy of my life is to keep encouraging children to think beyond they could achieve easily. I understand children are adaptive to change and take things with an open mind. They are ready to experiment with new things and dare to dream big. I am fortunate to being a teacher by profession and thus I always attempt experimenting, observing, and participating with other children and adults. Children learn through play. From birth, children are active participants in building their own understanding. Teachers prepare the environment to help each child build on what they already know. It is such a great pleasure to observe every young kid that becomes excited and curious to know when we show them the Universe pictures and tell them about the strange objects in our Universe. So my aim is to keep them ignited by doing different activities throughout the year related to Space. I am always a firm believer of: Creativity is the key to success in the future, and primary education is where teachers can bring creativity in children at that level. One of my main ways of teaching is to conduct various presentations on The Solar System and beyond and debates on Space explorations. A Planet making project is one of the all-time favorite project for my students where they dare to dream to fly in the universe, and with their imagination, kids make different celestial objects and present them. To inculcate scientific attitude I arrange film screening, simulation exercises and quizzes on various topics of astronomy. Every year we celebrate World Space Week 4th to 10th of Oct. The motivation among all came through different hands-on activities like-painting, slogan competition, topics related to space, poetry and essay writing on various topics related to astronomy, assembly presentations in school. I am indeed overwhelmed when I started the very special Space and Astronomy club where young toddlers are involved in different activities like a star gazing program, conducting

  18. Postmodernity and the university

    Directory of Open Access Journals (Sweden)

    Peter Scott

    2012-09-01

    Full Text Available The utility of post-modernism as an interpretative framework for understanding the development of contemporary higher education systems is sharply contested. Critics argue that post-modernism is, at best, a set of ideas in aesthetics, literature and critical theory with limited relevance outside these domains and, at worst, a passing intellectual fashion that is now out-of-date. However, post-modernity —or, as some would prefer, late modernity or ‘fluid’ modernity — is perhaps a more useful idea. In 21stcentury society there are a number of trends, some structural such as the growth of a knowledge-based economy and development of new patterns of knowledge production; and some conceptual such as the reconfiguration of time and space and the recognition of ‘difference’ (and risk? as key factor in the constitution of social life (and individual identity, which have a direct impact on the university. This impact is felt in two ways — first, the university is a primary engine of these transformations. Secondly, the university is shaped by these transformations (both normatively and cognitively in terms of teaching and research and structurally in terms of its organisational characteristics, governance and managementLa utilidad del postmodernismo como marco interpretativo para comprender el desarrollo de los sistemas contemporáneos de educación superior ha sido severamente contestada. Los críticos argumentan que el postmodernismo es, como mucho, un conjunto de ideas en los ámbitos de la estética, literatura y teoría crítica con relevancia limitada fuera de esos campos y, a lo peor, una moda intelectual pasajera que actualmente está caducada. No obstante, la postmodernidad —o, como algunos preferirían, la modernidad tardía o modernidad «fluida»— es quizá una idea más útil.

    2015-06-01

    Full Text Available University rankings are extremely important not only for future student, but also for universities themselves. They have a large impact on the institutions of higher education. A lot of universities believe, that rankings help them to maintain and create a reputation. Ranking systems function as some kind of fashion arena, where universities make comparisons between themselves. Universities want to improve their position in published classifications, so very often they try to change their policy and strategy. They also try to influence the ranking indicators, for example by hiring Nobel Prize winners. Therefore, there is an increasing need for reliable and transparent information about schools. However universities need not only statistical data, but also the tools, which will be useful in their comparisons and evaluations. The article presents the possibility of using one of the methods of graphic presentation of multidimensional empirical data structure, so called RGM, proposed by M. Rybaczuk. Thanks to this method universities could easily compare one another. They also could identify the fields of their activities, in which they are able to be better. The proposed way of graphical presentation of the universities could be a useful addition to traditional rankings, which just show us a lists of schools from the best to the worst.

    Full Text Available In the face of global competition and rising challenges that higher education institutions (HEIs meet, it is imperative to increase innovativeness and efficiency of their management. Benchmarking can be the appropriate tool to search for a point of reference necessary to assess institution’s competitive position and learn from the best in order to improve. The primary purpose of the paper is to present in-depth analysis of benchmarking application in HEIs worldwide. The study involves indicating premises of using benchmarking in HEIs. It also contains detailed examination of types, approaches and scope of benchmarking initiatives. The thorough insight of benchmarking applications enabled developing classification of benchmarking undertakings in HEIs. The paper includes review of the most recent benchmarking projects and relating them to the classification according to the elaborated criteria (geographical range, scope, type of data, subject, support and continuity. The presented examples were chosen in order to exemplify different approaches to benchmarking in higher education setting. The study was performed on the basis of the published reports from benchmarking projects, scientific literature and the experience of the author from the active participation in benchmarking projects. The paper concludes with recommendations for university managers undertaking benchmarking, derived on the basis of the conducted analysis.

  5. A Self Organizing Universe

    Wagner, Orvin E.

    2001-05-01

    First Feynman and Wheeler suggested in-out waves associated with elementary particles. Quantum field theory has waves propagating backward in time producing standing waves. The math suggests that the sun also produces its own in-out waves which spaced and now stabilize the planets. The same is true for the gaseous planets with their sattelites. I propose two postulates (suggested by my work). (1) Longitudinal waves are produced by electromagnetic sources. These waves become standing waves because space(or the vacuum)responds with an automatic return wave related to the inertial nature of space.(2)Larger sources such as the sun excite smaller sources such as the planets with successively smaller sources producing shorter and shorter wavelengths at lower and lower power. The hierarchical nature is suggested by 1/f phenomena. The standing waves from larger sources produce the organizing forces for galaxy and star formation as well as the repeating structures of the universe. The wave effects were first found in plant organization and then it was observed that the waves are everywhere. See the Wagner web site.

  6. Universal Sparse Modeling

    Ramirez, Ignacio

    2010-01-01

    Sparse data models, where data is assumed to be well represented as a linear combination of a few elements from a dictionary, have gained considerable attention in recent years, and their use has led to state-of-the-art results in many signal and image processing tasks. It is now well understood that the choice of the sparsity regularization term is critical in the success of such models. In this work, we use tools from information theory, and in particular universal coding theory, to propose a framework for designing sparsity regularization terms which have several theoretical and practical advantages when compared to the more standard l0 or l1 ones, and which lead to improved coding performance and accuracy in reconstruction and classification tasks. We also report on further improvements obtained by imposing low mutual coherence and Gram matrix norm on the corresponding learned dictionaries. The presentation of the framework and theoretical foundations is complemented with examples in image denoising and c...

Bevacizumab (BEV, a humanized immunoglobulin G1 monoclonal antibody that inhibits VEGF has demonstrated activity against recurrent high-grade gliomas (HGG in phase II clinical trials. Patients and Methods. Data were collected from patients with recurrent HGG who initiated treatment with BEV outside a clinical trial protocol at two Belgian university hospitals. Results. 19 patients (11 M/8 F were administered a total of 138 cycles of BEV (median 4, range 1–31. Tumor response assessment by MRI was available for 15 patients; 2 complete responses and 3 partial responses for an objective response rate of 26% for the intent to treat population were observed on gadolinium-enhanced T1-weighted images; significant regressions on T2/FLAIR were documented in 10 out of 15 patients (67%. A reduced uptake on PET was documented in 3 out of 4 evaluable patients. The six-month progression-free survival was 21% (95% CI 2.7–39.5. Two patients had an ongoing tumor response and remained free from progression after 12 months of BEV treatment. Conclusions. The activity and tolerability of BEV were comparable to results from previous prospective phase II trials. Reduced uptake on PET suggests a metabolic response in addition to an antiangiogenic effect in some cases with favorable clinical outcome.

    2016-01-01

    In this PhD thesis, we investigate generic features of inflation which are strictly related to fundamental aspects of UV-physics scenarios, such as string theory or supergravity. After a short introduction to standard and inflationary cosmology, we present our research findings. On the one hand, we show that focusing on universality properties of inflation can yield surprisingly stringent bounds on its dynamics. This approach allows us to identify the regime where the inflationary field range is uniquely determined by both the tensor-to-scalar ratio and the spectral index. Then, we derive a novel field-range bound, which is two orders of magnitude stronger than the original one derived by Lyth. On the other hand, we discuss the embedding of inflation in supergravity and prove that non-trivial hyperbolic K\\"ahler geometries induce an attractor for the inflationary observables: the spectral tilt tends automatically to the center of the Planck dome whereas the amount of primordial gravitational waves is directly...

I first recall how the idea originated from considerations on black hole thermodynamics and the so-called information paradox that arises when Hawking radiation is taken into account. String Quantum Gravity tried to solve the puzzle using the AdS/CFT correspondence, according to which a black hole in a 5-D anti-de Sitter space is like a flat 4-D field of particles and radiation. Although such an interesting holographic property, also called gauge/gravity duality, has never been proved rigorously, it has impulsed a number of research programs in fields as diverse as nuclear physics, condensed matter physics, general relativity and cosmology. I finally discuss the pros and cons of the holographic conjecture, and emphasizes the key role played by black holes for understanding quantum gravity and possible dualities between distant fields of theoretical p...

  10. Universal mechatronics coordinator

    Muir, Patrick F.

    1999-11-01

    Mechatronic systems incorporate multiple actuators and sensor which must be properly coordinated to achieve the desired system functionality. Many mechatronic systems are designed as one-of-a-kind custom projects without consideration for facilitating future system or alterations and extensions to the current syste. Thus, subsequent changes to the system are slow, different, and costly. It has become apparent that manufacturing processes, and thus the mechatronics which embody them, need to be agile in order to more quickly and easily respond to changing customer demands or market pressures. To achieve agility, both the hardware and software of the system need to be designed such that the creation of new system and the alteration and extension of current system is fast and easy. This paper describes the design of a Universal Mechatronics Coordinator (UMC) which facilitates agile setup and changeover of coordination software for mechatronic systems. The UMC is capable of sequencing continuous and discrete actions that are programmed as stimulus-response pairs, as state machines, or a combination of the two. It facilitates the modular, reusable programing of continuous actions such as servo control algorithms, data collection code, and safety checking routines; and discrete actions such as reporting achieved states, and turning on/off binary devices. The UMC has been applied to the control of a z- theta assembly robot for the Minifactory project and is applicable to a spectrum of widely differing mechatronic systems.

  11. Hydrogen fuel - Universal energy

    Science.gov (United States)

    Prince, A. G.; Burg, J. A.

    The technology for the production, storage, transmission, and consumption of hydrogen as a fuel is surveyed, with the physical and chemical properties of hydrogen examined as they affect its use as a fuel. Sources of hydrogen production are described including synthesis from coal or natural gas, biomass conversion, thermochemical decomposition of water, and electrolysis of water, of these only electrolysis is considered economicially and technologically feasible in the near future. Methods of production of the large quantities of electricity required for the electrolysis of sea water are explored: fossil fuels, hydroelectric plants, nuclear fission, solar energy, wind power, geothermal energy, tidal power, wave motion, electrochemical concentration cells, and finally ocean thermal energy conversion (OTEC). The wind power and OTEC are considered in detail as the most feasible approaches. Techniques for transmission (by railcar or pipeline), storage (as liquid in underwater or underground tanks, as granular metal hydride, or as cryogenic liquid), and consumption (in fuel cells in conventional power plants, for home usage, for industrial furnaces, and for cars and aircraft) are analyzed. The safety problems of hydrogen as a universal fuel are discussed, noting that they are no greater than those for conventional fuels.

  12. Outside the Gutenberg Universe

    Full Text Available Technological development has changed the media and formats for recording information, as well as the methods for their collection, preservation, reproduction and use. After six and a half centuries since the invention of printing press, electronic publications on Internet represent a revolutionary break-through in communication and data transmission. The new format has changed the publication to the extent that the library science should re-define the topic of its research, and re-consider the methods and procedures for its treatment. Consequently, the library science should refer to the underlying terminological and typological research, and re-define the subject of bibliographic processing and determine the elements for the subject’s identification. The new technological platform of electronic publications opens a range of possibilities, which make the significance and value of the established methods of knowledge management very relative, and thus also the basis of the library science and its “raisson d’ętre”. No cultural value is attached to electronic publications due to their specific characteristics, as it has been attached to a book in our civilization. Therefore, collection and long-term preservation of this material is not problematic only from the technological but also from the sociological aspect. By dealing with electronic media, library theory and practice finally step from the area of the known laws of the Gutenberg universe into the new space, where the new working rules will have to be established.

  13. Water in the Universe

    2011-01-01

    Due to its specific chemical and physical properties, water is essential for life on Earth. And it is assumed that this would be the case for extraterrestrial life as well. Therefore it is important to investigate where water can be found in the Universe. Although there are places that are completely dry, places where the last rainfall happened probably several 100 million years ago, surprisingly this substance is quite omnipresent. In the outer solar system the large satellites of Jupiter and Saturn are covered by a thick layer of ice that could be hiding a liquid ocean below. This of course brings up the question of whether the recently detected extrasolar planets could have some water on their surfaces and how we can detect this. Water molecules are also found in interstellar gas and dust clouds. This book begins with an introductory chapter reviewing the physical and chemical properties of water. Then it illuminates the apparent connection between water and life. This is followed by chapters dealing with ...

  14. Universities and Patent Demands.

    Cordova, Andrew K; Feldman, Robin

    2015-11-01

    Research universities have made enormous contributions to the field of medicine and the treatment of human disease. Alone or in collaboration with pharmaceutical companies, academic researchers have added to the store of knowledge that has led to numerous life science breakthroughs. A new chapter may be opening for academic researchers, however, that could lead to a darker tale. 'The mouse that trolled: the long and tortuous history of a gene mutation patent that became an expensive impediment to Alzheimer's research, by Bubela et al., chronicles one such tale.' The authors do an excellent job of bringing to life the twisting saga that engulfed numerous academic and non-profit Alzheimer's researchers over many years. The authors note that the story is an outlier, but sadly, that may not be the case. There are increasing signs that academic researchers and their institutions are being caught up in the rush for gold that is accompanying the proliferation of the non-practicing entity business model. As I have noted before, academic institutions have a dual role, as keepers of the academic flame and guardians of the public monies entrusted to them through state and federal research funding. The specter of taxpayer money being used, not to advance research and for the betterment of society, but as part of schemes to extract money from productive companies may not sit well with voters, and ultimately, with legislators. In that case, researchers and institutions themselves may have much to lose.

Is it possible to be sure in this theory correctness, which persuading of the Universe origination from the singularity fluctuation, when the World had appeared from nowhere, that is from abstract nothingness, further accelerated expansion of the Universe following the Big Bang, and its development up to present with inexplicable source of energy for that. However, in the extreme end of the meta-universe the speed of stellar formations runaway is about the light velocity. Further, there is a new problem, the finiteness of the Universe. There are two counter-opinions, if the expanding Universe is finite or infinite. A very important question arises here, the question regarding isolatedness of the Universe as a system. The problem of the Universe heat death (when the matter will stop its movement is closely connected with it. For this reason it is the time to discuss the Universe entropy. There is a short description of notions and problems with reference to this branch of knowledge, as well as of Doppler and Ritz effects alongside with Habble Law. The authors’ detailed interpretation of an entropy is also suggested. The analysis of the existing model is followed by the idea of the authors about the Universe organization. The style of the article is popular-science. In the first part of the article the existing concept of the Expanding Universe Theory and the dynamical Friedmann-Lemaitre models are described; it deals with the existing concept of the Big Bang Theory as well as the dark energy and the dark matter notions.

  18. The Black Hole Universe Model

    Science.gov (United States)

    Zhang, Tianxi

    2014-06-01

    The black hole universe model is a multiverse model of cosmology recently developed by the speaker. According to this new model, our universe is a fully grown extremely supermassive black hole, which originated from a hot star-like black hole with several solar masses, and gradually grew up from a supermassive black hole with million to billion solar masses to the present state with trillion-trillion solar masses by accreting ambient matter or merging with other black holes. The entire space is structured with infinite layers or universes hierarchically. The innermost three layers include the universe that we live, the inside star-like and supermassive black holes called child universes, and the outside space called mother universe. The outermost layer is infinite in mass, radius, and entropy without an edge and limits to zero for both the matter density and absolute temperature. All layers are governed by the same physics and tend to expand physically in one direction (outward or the direction of increasing entropy). The expansion of a black hole universe decreases its density and temperature but does not alter the laws of physics. The black hole universe evolves iteratively and endlessly without a beginning. When one universe expands out, a new similar one is formed from inside star-like and supermassive black holes. In each of iterations, elements are resynthesized, matter is reconfigurated, and the universe is renewed rather than a simple repeat. The black hole universe is consistent with the Mach principle, observations, and Einsteinian general relativity. It has only one postulate but is able to explain all phenomena occurred in the universe with well-developed physics. The black hole universe does not need dark energy for acceleration and an inflation epoch for flatness, and thus has a devastating impact on the big bang model. In this talk, I will present how this new cosmological model explains the various aspects of the universe, including the origin

While appreciating the central role of the four dimensions of university autonomy – organisational, financial, human resource, and academic – the authors conjecture...... that a fuller understanding of university autonomy can only be obtained through a holistic view of the complex inter-relationships between stakeholders and policies which can reinforce and, equally, pull in opposite directions. This holistic view is represented in a model of institutional university autonomy......, which is discussed at length in the chapter. The authors conclude by presenting international case studies that give new insights and reinforce our understanding that the issues relating to institutional university autonomy are genuinely global....

  20. Closed-universe recollapse conjecture

    Energy Technology Data Exchange (ETDEWEB)

    Barrow, J.D.; Galloway, G.J.; Tipler, F.J.

    1986-12-15

    It is widely believed that all expanding S/sup 3/ closed universes that satisfy the standard energy conditions recollapse to a second singularity. It is shown that this is false even for Friedmann universes: an ever-expanding S/sup 3/ Friedmann universe is constructed in which the matter tensor satisfies the strong, weak and dominant energy conditions and the generic condition. A general recollapse theorem for Friedmann universes is proved if the positive pressure criterion, dominant enery condition and matter regularity condition hold, then an S/sup 3/ Friedmann universe must recollapse. It is shown that all known vacuum solutions with Cauchy surface topology S/sup 3/ or S/sup 2/XS/sup 1/ recollapse, and we conjecture that this is a property of all vacuum solutions of Einstein's equations with such Cauchy surfaces.

  1. Cognitive biases and language universals

    CERN Document Server

    Baronchelli, Andrea; Puglisi, Andrea

    2013-01-01

    Language universals have been longly attributed to an innate Universal Grammar. An alternative explanation states that linguistic universals emerged independently in every language in response to shared cognitive, though non language-specific, biases. A computational model has recently shown how this could be the case, focusing on the paradigmatic example of the universal properties of color naming patterns, and producing results in accurate agreement with the experimental data. Here we investigate thoroughly the role of a cognitive bias in the framework of this model. We study how, and to what extent, the structure of the bias can influence the corresponding linguistic universal patterns. We show also that the cultural history of a group of speakers introduces population-specific constraints that act against the uniforming pressure of the cognitive bias, and we clarify the interplay between these two forces. We believe that our simulations can help to shed light on the possible mechanisms at work in the evol...

  2. A Model of Nonsingular Universe

    Directory of Open Access Journals (Sweden)

    Changjun Gao

    2012-07-01

    Full Text Available In the background of Friedmann–Robertson–Walker Universe, there exists Hawking radiation which comes from the cosmic apparent horizon due to quantum effect. Although the Hawking radiation on the late time evolution of the universe could be safely neglected, it plays an important role in the very early stage of the universe. In view of this point, we identify the temperature in the scalar field potential with the Hawking temperature of cosmic apparent horizon. Then we find a nonsingular universe sourced by the temperature-dependent scalar field. We find that the universe could be created from a de Sitter phase which has the Planck energy density. Thus the Big-Bang singularity is avoided.

    2011-01-01

    In this paper we present a method to obtain Banach spaces of universal and almost-universal disposition with respect to a given class $\\mathfrak M$ of normed spaces. The method produces, among other, the Gurari\\u{\\i} space $\\mathcal G$ (the only separable Banach space of almost-universal disposition with respect to the class $\\mathfrak F$ of finite dimensional spaces), or the Kubis space $\\mathcal K$ (under {\\sf CH}, the only Banach space with the density character the continuum which is of universal disposition with respect to the class $\\mathfrak S$ of separable spaces). We moreover show that $\\mathcal K$ is not isomorphic to a subspace of any $C(K)$-space -- which provides a partial answer to the injective space problem-- and that --under {\\sf CH}-- it is isomorphic to an ultrapower of the Gurari\\u{\\i} space. We study further properties of spaces of universal disposition: separable injectivity, partially automorphic character and uniqueness properties.

  4. Universality of market superstatistics

    Denys, Mateusz; Gubiec, Tomasz; Kutner, Ryszard; Jagielski, Maciej; Stanley, H. Eugene

    2016-10-01

    We use a key concept of the continuous-time random walk formalism, i.e., continuous and fluctuating interevent times in which mutual dependence is taken into account, to model market fluctuation data when traders experience excessive (or superthreshold) losses or excessive (or superthreshold) profits. We analytically derive a class of "superstatistics" that accurately model empirical market activity data supplied by Bogachev, Ludescher, Tsallis, and Bunde that exhibit transition thresholds. We measure the interevent times between excessive losses and excessive profits and use the mean interevent discrete (or step) time as a control variable to derive a universal description of empirical data collapse. Our dominant superstatistic value is a power-law corrected by the lower incomplete gamma function, which asymptotically tends toward robustness but initially gives an exponential. We find that the scaling shape exponent that drives our superstatistics subordinates itself and a "superscaling" configuration emerges. Thanks to the Weibull copula function, our approach reproduces the empirically proven dependence between successive interevent times. We also use the approach to calculate a dynamic risk function and hence the dynamic VaR, which is significant in financial risk analysis. Our results indicate that there is a functional (but not literal) balance between excessive profits and excessive losses that can be described using the same body of superstatistics but different calibration values and driving parameters. We also extend our original approach to cover empirical seismic activity data (e.g., given by Corral), the interevent times of which range from minutes to years. Superpositioned superstatistics is another class of superstatistics that protects power-law behavior both for short- and long-time behaviors. These behaviors describe well the collapse of seismic activity data and capture so-called volatility clustering phenomena.

    In distant 1972, within framework of the Internal Clinic, a cardiologic department was organized which was soon, on 29.XII.1974, transformed into the Cardiology Clinic, later the Institute for Heart Diseases, and in 2008 was renamed the University Cardiology Clinic. The greater part of its foundation was possible owing to Prof. Dimitar Arsov and Prof. Radovan Percinkovski, who was the clinic's first director in the period from 1974 to 1984. In 1985, the Clinic moved into its own new building, and in that way was physically detached from the Internal Clinics. Until its move to the new building, the Clinic functioned in the Internal Clinics building, organized as an outpatient polyclinic and inpatient infirmary department with clinical beds, a coronary intensive care unit and a haemodynamics laboratory equipped with the most modern equipment of that time. Today the Clinic functions through two integral divisions: an inpatient infirmary department which comprises an intensive coronary care unit and fourteen wards which altogether have 139 clinical beds, and the diagnostic centre which comprises an emergency clinic and day hospital, a communal and consultative outpatients' clinic functioning on a daily basis, through which some 300-350 patients pass every day, and diagnostic laboratories with a capacity of nearly 100 non-invasive and 20-30 invasive diagnostic procedures daily. The Clinic is a teaching base, and its doctors are educators of students at the Medical, Dental and Pharmacy Faculties, and also of students at the High School for Nurses and X-ray technicians, but also for those in Internal Medicine and especially Cardiology. The Clinic is also a base for scientific Masters' and post-doctoral studies, and such higher degrees are achieved not only by doctors who work here, but also by doctors from Medical Centres both in the country and abroad. Doctors working in this institution publish widely, not only a great number of books and monographs, but also original

    2008-04-01

    The Soldier Universal Robot Controller (SURC) is a modular OCU designed for simultaneous control of heterogeneous unmanned vehicles. It has a well defined, published API., defined using XML schemas, that allows other potential users of the system to develop their own modules for rapid integration with SURC. The SURC architecture is broken down into three layers: User Interface, Core Functions, and Transport. The User Interface layer is the front end module which provides the human computer interface for user control of robots. The Core layer is further divided into the following modules: Capabilities, Tactical, Mobility, and World Model. The Capabilities module keeps track of the known robots and provides a list of specifications and services. The Mobility module provides path planning via D*, while the Tactical module provides higher level mission planning (multi-agent/multi-mission) capabilities for collaborative operations. The World Model module is a relational database which stores world model objects. Finally, a Transport module provides translation from the SURC architecture to the robot specific messaging protocols (such as JAUS). This allows fast integration of new robot protocols into an existing SURC implementation to enable a new system to rapidly leverage existing SURC capabilities. The communication between different modules within the SURC architecture is done via XML. This gives developers and users the flexibility to extend existing messages without breaking backwards compatibility. The modularity of SURC offers users and developers alike the capability to create custom modules and plug them into place, as long as they follow the pre defined messaging API for that module.

  8. Universality and Beyond

    Directory of Open Access Journals (Sweden)

    Phillips D.R.

    2010-04-01

    Full Text Available I discuss the impact of a finite effective range, r, on systems with a large two-body scattering length, a. In particular, I show how observables can be written as an expansion around the “universal”, or large-scatteringlength limit. The parameter governing this expansion is the ratio r/a. In few-nucleon systems the ratio r/a has a value of about 1/3, and so such corrections are essential in producing good agreement between theory and data. Hence, I first show how these effects range play a key role in making the so-called “pionless” effective field theory a successful descriptor of low-energy processes in the NN system. I then move to the NNN system, and review predictions for the energy-dependence of observables there. However, the beautiful Efimov physics associated with the presence of a large scattering length is not fully revealed in the NNN system, precisely because r/a corrections are large. I therefore turn to cold atomic gases and show that there are some important recent experiments where physics “beyond universality” affects the data. In the process I demonstrate that an additional piece of short-distance physics is necessary to renormalize scattering-length-dependent observables in the three-body system once corrections ∼ r are considered. Finally, I discuss recent initial efforts to compute r/a corrections to the predictions of universality for the four-body system.

    In this work, we describe a strategy for the detection and characterization of microorganisms associated with a potential biological warfare attack or a natural outbreak of an emerging infectious disease. This approach, termed TIGER (Triangulation Identification for the Genetic Evaluation of Risks), relies on mass spectrometry-derived base composition signatures obtained from PCR amplification of broadly conserved regions of the microbial genome(s) in a sample. The sample can be derived from air filtration devices, clinical samples, or other sources. Core to this approach are "intelligent PCR primers" that target broadly conserved regions of microbial genomes that flank variable regions. This approach requires that high-performance mass measurements be made on PCR products in the 80-140 bp size range in a high-throughput, robust modality. As will be demonstrated, the concept is equally applicable to bacteria and viruses and could be further applied to fungi and protozoa. In addition to describing the fundamental strategy of this approach, several specific examples of TIGER are presented that illustrate the impact this approach could have on the way biological weapons attacks are detected and the way that the etiologies of infectious diseases are determined. The first example illustrates how any bacterial species might be identified, using Bacillus anthracis as the test agent. The second example demonstrates how DNA-genome viruses are identified using five members of Poxviridae family, whose members includes Variola virus, the agent responsible for smallpox. The third example demonstrates how RNA-genome viruses are identified using the Alphaviruses (VEE, WEE, and EEE) as representative examples. These examples illustrate how the TIGER technology can be applied to create a universal identification strategy for all pathogens, including those that infect humans, livestock, and plants.

  10. Asian top universities in six world university ranking systems

    Full Text Available There are a variety of ranking systems for universities throughout the different continents of the world. The majority of the world ranking systems have paid special attention toward evaluation of universities and higher education institutions at the national and international level. This paper tries to study the similarities and status of top Asian universities in the list of top 200 universities by these world ranking systems. Findings show that there are some parallelisms among these international rankings. For example it was found some correlations between QS-Webometrics rankings (R= 0.78; QS-THE rankings (R= 0.53; and Shanghai-HEEACT rankings (R= 0.58. The highest correlation rate belongs to QS-Webometrics (R=0.78. The findings show no evidence to prove that the origin country of ranking system has any bias toward the rank of universities of its own country among other countries. For instance QS ranking of the United States classifies many universities of China and Japan as top Asian universities. HEEACT Ranking System of Taiwan includes just one university of Taiwan in the high ranking category (as other rankings do. Shanghai Ranking of China assigns a lower grade to universities of China and Hong Kong in comparison with QS ranking of the USA. Finally, some suggestions are made to improve the benefits of the ranking systems in order to promote the situation of higher education in the world, and recommendations for combining the indicators of these ranking systems to have a more comprehensive one for the world.

The aim of the article is to define the importance of participation in World or National universities rankings for higher university institutions as an effective tool in development and improvement of higher education system in total. The results of the analysis. Today the educational market actively interact universities (enterprises that provide educational services and consumers (students who choose university and receive services. The main feature is the intangibility of educational services. Education is intangible and therefore difficult to assess its quality until purchased. Educational services require engineering experience of beneficiaries: university should make a clear image of what perception of reality and knowledge it wants to form for customer. It is important to develop together operational and contextual reinforcements of this impression. Educational services also feature inseparability of service provider. The process of providing educational services and consumption are almost always simultaneous. It should be mentioned that for a long time universities functioned as closed structures, the aim of which is fundamental and applied research and commercialization of their results. Nowadays new market realities show the necessity to provide new managerial forms of modern university. The top task of any university today is not only hiring students, but search for partners and providing of scientific research also. That is where international ratings help. International ratings become indicators of prestige. Relying on the rating results many decisions are made (i. e. decision on university to study, decision on scientific or business partnership. The most authoritative international university rankings are ARWU, QS World University Ranking and Times Higher Education. Ukrainian universities should focus on them in planning their foreign marketing policy. University rankings can be a competitive business

    Weak gravitational lensing is an effective tool to map the structure of matter in the universe, and has been used for more than ten years as a probe of the nature of dark energy. Beyond the well-established two-point summary statistics, attention is now turning to methods that use the full statistical information available in the lensing observables, through analysis of the reconstructed shear field. This offers an opportunity to take advantage of powerful deep learning methods for image analysis. We present two early studies that demonstrate that deep learning can be used to characterise features in weak lensing convergence maps, and to identify the underlying cosmological model that produced them.We developed an unsupervised Denoising Convolutional Autoencoder model in order to learn an abstract representation directly from our data. This model uses a convolution-deconvolution architecture, which is fed with input data (corrupted with binomial noise to prevent over-fitting). Our model effectively trains itself to minimize the mean-squared error between the input and the output using gradient descent, resulting in a model which, theoretically, is broad enough to tackle other similarly structured problems. Using this model we were able to successfully reconstruct simulated convergence maps and identify the structures in them. We also determined which structures had the highest “importance” - i.e. which structures were most typical of the data. We note that the structures that had the highest importance in our reconstruction were around high mass concentrations, but were highly non-Gaussian.We also developed a supervised Convolutional Neural Network (CNN) for classification of weak lensing convergence maps from two different simulated theoretical models. The CNN uses a softmax classifier which minimizes a binary cross-entropy loss between the estimated distribution and true distribution. In other words, given an unseen convergence map the trained CNN determines

    Four hundred years ago two astronomical world views hung in the balance: the geocentric and the heliocentric. Today astronomy faces a similar choice between two grand world views: a purely physical universe, in which cosmic evolution commonly ends in planets, stars and galaxies, and a biological universe, in which cosmic evolution routinely results in life, mind and intelligence. Astrobiology is the science providing the data to make this critical choice. This 20th century overview shows how we have arrived at the view that cosmic evolution may have resulted in life and intelligence in the universe. It examines how our astronomical world view has changed over the last century, recalls the opinions of astronomical pioneers like Russell, Shapley, and Struve on life in the universe, and shows how planetary science, planetary systems science, origins of life studies and SETI have combined to form a new discipline. Astrobiology now commands \\$50 million in direct funding from NASA, funds 15 Astrobiology Institute members around the country and four affiliates around the world, and seeks to answer one of astronomy's oldest questions. Whether we live in a mostly physical universe, as exemplified in Isaac Asimov's Foundation series, or in a biological universe, as portrayed in Arthur C. Clarke's works, this reality will have profound consequences, no less than the Copernican theory. Astrobiology also looks to the future of life; taking a long-term ``Stapledonian" view, it is possible we may live in a postbiological universe.

    Full Text Available In a recent paper, the expression a ( t = e H 0 T 0 [ ( t T 0 where = 0 : 5804, was proposed for the expansion factor of our Universe. According to it, gravity dominates the expan- sion ( matter era until the age of T ⋆ = 3 : 214 Gyr and, after that, dark energy dominates ( dark energy era leading to an eternal expansion, no matter if the Universe is closed, flat or open. In this paper we consider only the closed version and show that there is an upper limit for the size of the radial comoving coordinate, beyond which nothing is observed by our fundamental observer, on Earth. Our observable Universe may be only a tiny portion of a much bigger Universe most of it unobservable to us. This leads to the idea that an endless number of other fundamental observers may live on equal number of Universes similar to ours. Either we talk about many Universes — Multiverse — or about an unique Universe, only part of it observable to us.

    Research into the oral and literary traditions of scholastic education usually emphasizes the significance of the world in late medieval pedagogy. This paper suggests that coded hand signals provided early university scholars with an important non-verbal means of communication too. Using illustrations of classroom scenes from early university manuscripts, this paper analyzes the artistic conventions for representating gestures that these images embody. By building up a typology of these gesticulations, it demonstrates that the producers of these images and their audience shared a perception of scholastic education that embraced a sophisticated understanding of the activities associated with university education.

    Universal planetary tectonics (supertectonics) G. Kochemasov IGEM of the Russian Academy of Sciences, Moscow, Russia, kochem.36@mail.ru The wave planetology [1-3 & others] proceeds from the following: "planetary structures are made by orbits and rotations". A uniform reason makes uniform structures. Inertia-gravity waves arising in planetary bodies due to their movements in Keplerian elliptical orbits with periodically changing accelerations warp these bodies in such way that they acquire polyhedron shapes (after interference of standing waves of four directions). Strong Newtonian gravity makes bodies larger than ~400 to 500 km in diameter globular and polyhedra are rarely seen. Only geomorphologic, geologic and geophysical mapping can develop these hidden structures. But small bodies, normally less than ~ 300 to 400 km in diameter, often show parts of the polyhedra, rarely fully developed forms (the asteroid Steins and satellite Amalthea present rather perfect forms of "diamond"). Depending on warping wavelengths (they make harmonics) various Plato's figures superimposed on each other can be distinguished. The fundamental wave 1 produces a tetrahedron, intrinsically dichotomic figure in which a vertex (contraction) always is opposed to a face (expansion). From the recent examples the best is the saturnian northern hexagon (a face) opposed to the southern hurricane (a vertex). The first overtone wave 2 is responsible for creation of structural octahedra. Whole ‘diamonds" and their parts are known [4, 5]. Other overtones produce less developed (because of smaller wave amplitudes) planetary shapes complicating main forms. Thus, the first common structural peculiarity of planetary bodies is their polyhedron nature. Not less important is the second common structural peculiarity. As all globular or smaller more or less isometric bodies rotate, they have an angular momentum. It is inevitably different in tropic and extra-tropic belts having uneven radii or distances to

    Full Text Available It is widely accepted that universities can play critical roles in promoting sustainability. In the United States and China, many universities have initiated sustainability programs. Employing Indiana University, Bloomington, the U.S. (IUB and Tsinghua University, Beijing, China (Tsinghua as two cases, we examine the conceptualization and implementation of university sustainability programs through a comparison of their respective definitions, goals, organizational dynamics, and strategies. We find that IUB’s sustainability scheme is more detailed and specific, while Tsinghua’s is more general; this is principally attributable to differences in national and local contexts. Furthermore, IUB values the environmental, economic, and social aspects of university sustainability equally, while Tsinghua focuses more on the environmental aspect. In addition, IUB has a more loosely-structured and more inclusive sustainability organizational dynamic while Tsinghua has a more hierarchical one. This comparative study helps us to understand how these two research universities understand and implement sustainability within the respective cultural, political, and institutional contexts of the United States and China.

    2014-01-15

    We study the third quantization of the Friedmann-Robertson-Walker cosmology with N-minimal massless fields. The third quantized Hamiltonian for the Wheeler-DeWitt equation in the minisuperspace consists of infinite number of intrinsic time-dependent, decoupled oscillators. The Hamiltonian has a pair of invariant operators for each universe with conserved momenta of the fields that play a role of the annihilation and the creation operators and that construct various quantum states for the universe. The closed universe exhibits an interesting feature of transitions from stable states to tachyonic states depending on the conserved momenta of the fields. In the classical forbidden unstable regime, the quantum states have googolplex growing position and conjugate momentum dispersions, which defy any measurements of the position of the universe.

    How can effective barotropic matter emerge from the interaction of cosmological fluids in an isotropic and homogeneous cosmological model? The dynamics of homogeneous and isotropic Friedmann-Lema\\^itre-Robertson-Walker universes is a natural special case of generalized Lotka-Volterra systems where each of the universe's fluid components can be seen as a competitive species in a predator-prey model. (Jungle universe : arXiv:1306.1037) In addition to numerical simulations illustrating this behaviour among the barotropic fluids filling the universe, we analytically pinpoint that effective time-dependent barotropic indices can arise from a physical coupling between those fluids whose dynamics could then look like that of another type of cosmic fluid, such as a cosmological constant. Since the nature of dark energy is still unknown, this dynamical approach could help understanding some of the properties of dark matter and dark energy at large cosmological scales.

    2016-10-01

    The possibility of an emergent universe solution to Einstein's field equations allowing for an irreversible creation of matter at the expense of the gravitational field is shown. With the universe being chosen as spatially flat FRW spacetime together with equation of state proposed in Mukherjee et al. (Class. Quant. Grav. 23, 6927, 2006), the solution exists when the ratio of the phenomenological matter creation rate to the number density times the Hubble parameter is a number β of the order of unity and independent of time. The thermodynamic behaviour is also determined for this solution. Interestingly, we also find that an emergent universe scenario is present with usual equation of state in cosmology when the matter creation rate is chosen to be a constant. More general class of emergent universe solutions are also discussed.

    Full Text Available This article surveys studies on universally balanced properties of cooperative games defined in a succinct form. In particular, we focus on combinatorial optimization games in which the values to coalitions are defined through linear optimization programs, possibly combinatorial, that is subject to integer constraints. In economic settings, the integer requirement reflects some forms of indivisibility. We are interested in the classes of games that guarantee a non-empty core no matter what are the admissible values assigned to the parameters defining these programs. We call such classes universally balanced. We present characterization and complexity results on the universally balancedness property for some classes of interesting combinatorial optimization games. In particular, we focus on the algorithmic properties for identifying universally balancedness for the games under discussion.

    Full Text Available The present article sets out to clarify the concepts of storytelling and branding, with a focus on university branding and visual identity – the latter being a vital element to a brand’s uniqueness. Storytelling is an important method of brand construction, and it entails a strong power of seduction. Branding is increasingly more about storytelling. Practically, a story is an image made up of facts, feelings and interpretations, which are often told to us solely by the university itself. As such, the brand appears on the market accompanied by its identity. Identity is what we aim to express with help of the brand. Implementing a system of visual identity that would help to harmoniously develop a university brand requires a handbook of visual identity. The present article aims to be a starting point for such a handbook serving the University of Bucharest, which currently does not own such a handbook

  1. Universe creation on a computer

    Science.gov (United States)

    McCabe, Gordon

    The purpose of this paper is to provide an account of the epistemology and metaphysics of universe creation on a computer. The paper begins with F.J. Tipler's argument that our experience is indistinguishable from the experience of someone embedded in a perfect computer simulation of our own universe, hence we cannot know whether or not we are part of such a computer program ourselves. Tipler's argument is treated as a special case of epistemological scepticism, in a similar vein to 'brain-in-a-vat' arguments. It is argued that Tipler's hypothesis that our universe is a program running on a digital computer in another universe, generates empirical predictions, and is therefore a falsifiable hypothesis. The computer program hypothesis is also treated as a hypothesis about what exists beyond the physical world, and is compared with Kant's metaphysics of noumena. It is argued that if our universe is a program running on a digital computer, then our universe must have compact spatial topology, and the possibilities of observationally testing this prediction are considered. The possibility of testing the computer program hypothesis with the value of the density parameter Ω0 is also analysed. The informational requirements for a computer to represent a universe exactly and completely are considered. Consequent doubt is thrown upon Tipler's claim that if a hierarchy of computer universes exists, we would not be able to know which 'level of implementation' our universe exists at. It is then argued that a digital computer simulation of a universe, or any other physical system, does not provide a realisation of that universe or system. It is argued that a digital computer simulation of a physical system is not objectively related to that physical system, and therefore cannot exist as anything else other than a physical process occurring upon the components of the computer. It is concluded that Tipler's sceptical hypothesis, and a related hypothesis from Bostrom, cannot be

  2. Universality in the stock exchange

    We analyze the constituents stocks of the Dow Jones Industrial Average and the Standard & Poor's 100 index of the NYSE stock exchange market. Surprisingly, we discovered that the distribution of the fluctuations of the cubic root of the squared daily return are close to the universal non-parametric Bramwell-Holdsworth-Pinton (BHP) distribution. Since the BHP probability density function appears in several other dissimilar phenomena, our result reveals an universal feature of the stock exchange market.

    In this proceeding, the phenomenology of Universal Extra Dimensions (UED), in which all the Standard Model fields propagate, is explored. We focus on models with one universal extra dimension, compactified on an S{sub 1}/Z{sub 2} orbifold. We revisit calculations of Kaluza-Klein (KK) dark matter without an assumption of the KK mass degeneracy including all possible coannihilations. We then contrast the experimental signatures of low energy supersymmetry and UED.

    Full Text Available One of the key functions of universities is professional training. Performing professional tasks properly calls for not only acquisition of the appropriate technical competences, but also the development of ethical values. In order to adjust to the needs of society and students, university education should offer an integrated development model, which, in addition to technical and cognitive competences, also plans for the inclusion of personal and moral growth.

  7. Open Scholarship and Research Universities

    OpenAIRE

    2005-01-01

    Compare the cost per article for publication in commercial journals, not-profit journals, and open-access journals. For universities that support open-archives and open-access journal management software as part of standard university infrastructure, the financial cost of hosting an additional journal is quite low. Scholars who commit to editing and promoting a journal need to focus primarily on the intellectual tasks with little concern for finances.

  8. Boolean universes above Boolean models

    1993-01-01

    We establish several first- or second-order properties of models of first-order theories by considering their elements as atoms of a new universe of set theory, and by extending naturally any structure of Boolean model on the atoms to the whole universe. For example, complete f-rings are ``boundedly algebraically compact" in the language $( + , - , . , \\wedge , \\vee , \\leq )$, and the positive cone of a complete l-group with infinity adjoined is algebraically compact in the language $( + , \\v...

  9. A Universe without Weak Interactions

    Energy Technology Data Exchange (ETDEWEB)

    Harnik, Roni; Kribs, Graham D.; Perez, Gilad

    2006-04-07

    A universe without weak interactions is constructed that undergoes big-bang nucleosynthesis, matter domination, structure formation, and star formation. The stars in this universe are able to burn for billions of years, synthesize elements up to iron, and undergo supernova explosions, dispersing heavy elements into the interstellar medium. These definitive claims are supported by a detailed analysis where this hypothetical ''Weakless Universe'' is matched to our Universe by simultaneously adjusting Standard Model and cosmological parameters. For instance, chemistry and nuclear physics are essentially unchanged. The apparent habitability of the Weakless Universe suggests that the anthropic principle does not determine the scale of electroweak breaking, or even require that it be smaller than the Planck scale, so long as technically natural parameters may be suitably adjusted. Whether the multi-parameter adjustment is realized or probable is dependent on the ultraviolet completion, such as the string landscape. Considering a similar analysis for the cosmological constant, however, we argue that no adjustments of other parameters are able to allow the cosmological constant to raise up even remotely close to the Planck scale while obtaining macroscopic structure. The fine-tuning problems associated with the electroweak breaking scale and the cosmological constant therefore appear to be qualitatively different from the perspective of obtaining a habitable universe.

    As basic policy, NASA believes that colleges and universities should be encouraged to participate in the nation's space and aeronautics program to the maximum extent practicable. Indeed, universities are considered as partners with government and industry in the nation's aerospace program. NASA's objective is to have them bring their scientific, engineering, and social research competence to bear on aerospace problems and on the broader social, economic, and international implications of NASA's technical and scientific programs. It is expected that, in so doing, universities will strengthen both their research and their educational capabilities to contribute more effectively to the national well being. This annual report is one means of documenting the NASA-university relationship, frequently denoted, collectively, as NASA's University Program. This report is consistent with agency accounting records, as the data is obtained from NASA's Financial and Contractual Status (FACS) System, operated by the Financial Management Division and the Procurement Office. However, in accordance with interagency agreements, the orientation differs from that required for financial or procurement purposes. Any apparent discrepancies between this report and other NASA procurement or financial reports stem from the selection criteria for the data. This report was prepared by the Office of Education/N.

    Full Text Available The study was intended to recognize and replicate the Yukl’s (1989-2004 behavioral taxonomies in the university settings in Sindh. A comprehensive questionnaire based on the items in taxonomies was developed, face validity of the questionnaire was test and found suitable. A total of 90 university Deans and head of Departments were randomly selected from public and private universities of Sindh. Categorical reliability of the data was checked and found highly reliable. The majority of the respondents were male, post graduate, above 50 years of age, married and had more than 15 years of experience. The statistical analysis describes the typical Sindhi culture among the respondents. A large number of university leadership focused on the relation as compared to task and change at the universities. This research also supports partial replication of three dimensions i.e., Relation, Task and Change as Yukl’s behavioral taxonomies with first order factor analysis. Relation factor was replicated completely, while other two were replicated in two different facets each i.e., Change was replicated in two facets – Improvement and Process and Task was also replicated in two facets – Improvement and Process. Making a second order factor analysis assured these two factors were replicated completely.

    The ESA Euclid mission aims to understand why the expansion of the Universe is accelerating and pin down the source responsible for the acceleration. It will uncover the very nature of dark energy and gravitation by measuring with exquisite accuracy the expansion rate of the Universe and the growth rate of structure formation in the Universe. To achieve its objectives Euclid will observe the distribution of dark matter in the Universe by measuring shapes of weakly distorted distant galaxies lensed by foreground cosmic structures with the VIS imaging instrument. In parallel, Euclid will analyse the clustering of galaxies and the distribution of clusters of galaxies by using spectroscopy and measuring redshifts of galaxies with the NISP photometer and spectrometer instrument. The Euclid mission will observe one third of the sky (15,000 deg2) to collect data on several billion galaxies spread over the last ten billion years. In this presentation I will report on the considerable technical and scientific progresses made since COSPAR 2014, on behalf of the Euclid Collaboration. The recent mission PDR that has been passed successfully shows that Euclid should meet its requirements and achieve its primary scientific objectives to map the dark universe. The most recent forecasts and constraints on dark energy, gravity, dark matter and inflation will be presented.

  16. Accelerating Expansion of the Universe

    This thesis concentrates on the accelerated expansion of the Universe recently explored by measurements of redshift and luminosity-distance relations of type Ia Supernovae. We have considered a model of the universe filled with modified Chaplygin gas and barotropic fluid. The role of dynamical cosmological constant has been explored with Modified Chaplygin Gas as the background fluid. Various phenomenological models for \\Lambda have been studied in presence of the gravitational constant G to be constant or time dependent. A new form of the well known Chaplygin gas model has been presented by introducing inhomogeneity in the EOS. This model explains w=-1 crossing. An interaction of this model with the scalar field has also been investigated through a phenomenological coupling function. Tachyonic field has been depicted as dark energy model to represent the present acceleration of the Universe. A mixture of the tachyonic fluid has been considered with Generalized Chaplygin Gas to show the role of the later as a...

  17. Reionization of an Inhomogeneous Universe

    2001-01-01

    Full radiative transfer in 3D space has been solved to pursue the reionization history in an inhomogeneous universe. It has been shown that the reionization of an inhomogeneous universe is not a prompt event, but a fairly slow process. Also, QSO absorption line systems are simulated with using the results of radiative transfer calculations. Ly$\\alpha$ continuum depression implies that the metagalactic UV intensity decreases rapidly with $z$ at $z>5$, and the reionization must have taken place between $z=6$ and 10. Finally, it is stressed that H$\\alpha$ forest is a more powerful tool to probe the reionization history and the density fluctuations in the universe at $z>5$.
