Multiscale Coupling: Challenges and Opportunities

Multiscale coupling is ubiquitous in nature and attracts broad interests of scientists from mathematicians, physicists, machinists, chemists to biologists. However, much less attention has been paid to its intrinsic implication. In this paper, multiscale coupling is introduced by studying two typical examples in classic mechanics: fluid turbulence and solid failure. The nature of multiscale coupling in the two examples lies in their physical diversities and strong coupling over wide-range scales. The theories of dynamical system and statistical mechanics provide fundamental methods for the multiscale coupling problems. The diverse multiscale couplings call for unified approaches and might expedite new concepts, theories and disciplines.

The MBA-LBA I period in the Kourion region : new evidences from Erimi- Laonin tou Porakou (Lemesos, Cyprus)

The evidence from Erimi-Laonin tou Porakou within the Kouris valley settlement system can offer further new data to outline a picture of the development trends from MBA to LBA I periods in the Kourion region. As to this area, such a “transitional” phase could be particularly relevant to better understand the development process of the mature LBA II–III urban centers (in Alassa as well as the most recent discovered in Erimi-Pitharka). In 2008–2009 a focus investigation (an intensive survey, geoperspections and excavations) within the Kouris Valley Project has been addressed to the site of Erimi-Laonin tou Porakou, which lies on one of the highest hilltops facing southward the Kouris dam. The excavations evidenced a double circuit wall which surrounds the top mound and the lower terrace. The top mound (Area A) has been widely occupied by a complex workshop, directly linked with a storage area. The natural limestone bedrock has been worked out to arrange a system of carved deep basins connected each other by a series of flow channels. Southward from the workshop, a large storage area has been cleared, with a relevant assemblage of big pithoi and storage devices. The first lower terrace area (Area B) has been possibly occupied by a domestic quarter; a cemetery area (Area E) has been also evidenced outside the external circuit wall, where a series of five rock-cut tombs (Tombs 228– 232) with single chamber and small incoming dromoi has been excavated.

Experimental Study On Liquid Free Surface In Buoyant-Thermocapillary Convection

We investigate the surface deformations of buoyant-thermocapillary convection in a rectangular cavity clue to gravity and temperature gradient between the two sidewalls. The cavity is 52mm x 42mm in horizontal cross section, the thickness of liquid layer h is changed from 2.5mm to 6.5mm. Surface deformations of h = 3.5mm and 6.0mm are discussed and compared. Temperature difference is increased gradually, and the flow in the liquid layer will change from stable convection to unstable convection. Two kinds of optical diagnostic system with image processor are developed for study of the kinetics of buoyant-thermocapillary convection, they give out the information of liquid free surface. The quantitative results are calculated by Fourier transform and correlation analysis, respectively. With the increasing temperature gradient, surface deformations calculated are more declining. It is interesting phenomenon that the inclining directions of the convections in thin and thick liquid layers are different. For a thin layer, the convection is mainly controlled by thermocapillary effect. However, for a thick layer, the convection is mainly controlled by buoyancy effect. The surface deformation theoretically analysed is consistent with our experimental results. The present experiment proves that surface deformation is related to temperature gradient and thickness of the liquid layer. In other words, surface deformation lies on capillary convection and buoyancy convection.

Plane strain asymptotic fields for cracks terminating at the interface between elastic and pressure-sensitive dilatant materials

The plane strain asymptotic fields for cracks terminating at the interface between elastic and pressure-sensitive dilatant material are investigated in this paper. Applying the stress-strain relation for the pressure-sensitive dilatant material, we have obtained an exact asymptotic solution for the plane strain tip fields for two types of cracks, one of which lies in the pressure-sensitive dilatant material and the other in the elastic material and their tips touch both the bimaterial interface. In cases, numerical results show that the singularity and the angular variations of the fields obtained depend on the material hardening exponent n, the pressure sensitivity parameter mu and geometrical parameter lambda.

On the origin and foundation of the concept “The Person” metaphysical realism on interpersonal recognition

Resumen: De acuerdo con el autor, la capacidad del alma de conocerse a sí misma está en la raíz del problema de la persona. Más aún, el entendimiento deber ser interpretado antológicamente como una actividad del alma. Se lleva a cabo un análisis del concepto de persona en algunos filósofos medievales y modernos. También hay referencias a pensadores contemporáneos. El autor sostiene que la noción que Spaemann introduce, considerando la intencionalidad como meramente un sentimiento o negatividad, es insuficiente. El mencionado sentimiento subjetivo es idéntico al concepto de ‘intuición experienciante’ en la fenomenología; pero es insuficiente para permitirnos comprender la esencia de la persona como una entidad espiritual. El autor afirma que cada ser humano debería ser reconocido, no sólo como una creatura racional, sino también como persona, en especial cuando nos referimos a este ser humano o a esta alma. Agrega que las consecuencias prácticas de esta perspectiva son de gran importancia.

Amartya Sen : la idea de la justicia

Resumen: El artículo analiza la importancia del último libro publicado por Amartya Sen, La idea de la justicia, que representa una síntesis de todo su pensamiento. El autor destaca que la importancia de esta obra radica en su dimensión ética, guiada por la razón, y la compara con la teoría de John Rawls, trazando los paralelos y diferencias que existen entre el pensamiento de ambos intelectuales. Luego, Migliore expone los tres grandes temas abordados por Sen en su teoría: la cuestión de la distribución justa de los r ecursos, la democracia o libertad de participación, y los derechos humanos. Finalmente, a modo de conclusión, sugiere que la obra del economista indio tiene interesantes coincidencias con el pensamiento social cristiano.

Eli, Eli, Lama Shabaqtani” la condición cristiana en el Medio Oriente

Resumen: El artículo enfoca la situación de los cristianos del Medio Oriente y trata de formular su destino colectivo en términos de “la condición cristiana”. El argumento central sostiene que la tragedia de la condición cristiana en el Medio Oriente se explica por la crisis del Estado secular provocada tanto por el factor del Islam, así como las intervenciones de potencias europeas desde las cruzadas hasta el período colonial e intervención militar de Estados Unidos en Irak en 2003. En este sentido, la actualidad no es la repetición de la historia, sino la continuidad del mismo padrón de inequidad en distintos períodos históricos dentro de las sociedades musulmanas y el intervencionismo externo/occidental que, tanto en el pasado como en la actualidad, muy pocas veces se ha preocupado por el destino de la cristiandad del Medio Oriente.

Una teología samaritana : el estilo teológico de Jon Sobrino

El presente artículo se propone presentar las notas fundamentales de la teología de Jon Sobrino. Su particularidad radica en el abordaje en términos de estilo. El autor considera que el teologizar del sacerdote jesuita ha cobrado una identidad original y creadora que permite categorizarlo como estilo. Una de las tesis fuertes del artículo es la definición del teologizar de Sobrino en tanto “estilo” teológico. Luego de una fundamentación del enfoque estilístico que abreva fundamentalmente en H. U. von Balthasar y Ch. Theobald, se despliega la identidad de este estilo teológico en sus características. La otra tesis fuerte es que la realidad del sufrimiento histórico en América Latina configura centralmente el estilo teológico de Jon Sobrino, donde logos y pathos convergen en un movimiento único que cualifican su teología como teología samaritana o teología sentiente (X. Zubiri).

‘Neptune’ between ‘Hesperus’ and ‘Vulcan’: On descriptive names and non-existence

[EN]This work will focus on some aspects of descriptive names. The New Theory of Reference, in line with Kripke, takes descriptive names to be proper names. I will argue in this paper that descriptive names and certain theory in reference to them, even when it disagrees with the New Theory of Reference, can shed light on our understanding of (some) non-existence statements. I define the concept of descriptive name for hypothesised object (DNHO). My thesis being that DNHOs are, as I will specify, descriptions: a proposition expressed by the utterance ‘n is F’, where ‘n’ is a DNHO, is not singular at all; it is a descriptive proposition. To sum up, concerning proper names, the truth lies closer to the New Theory of Reference, but descriptivism is not altogether false. As for DNHOs descriptivism is, in some cases, the right fit.

O processo de implantação da gestão estratégica na Câmara dos Deputados

Analisa o processo de implantação da gestão estratégica na Câmara dos Deputados, tendo por base a experiência piloto desenvolvida na Diretoria de Recursos Humanos que envolveu a elaboração e a implementação do planejamento estratégico. Pretende descrever e explicar, à luz da bibliografia consultada, como foi a vivência naquela Diretoria, destacando a metodologia aplicada, os ajustes necessários, as experiências acumuladas e as lições aprendidas. A pretensão é extrair dessa dicotomia entre a teoria, consignada na literatura, e a prática da execução do plano estratégico, os conhecimentos considerados norteadores para experiências similares em órgãos do Poder Legislativo, constituindo-se em fonte de aprendizado relevante para projetos incipientes na área de estudo da gestão estratégica. Avalia, também, a importância da existência de um sistema de gestão voltado para o monitoramento e avaliação das estratégias deliberadas, sob a forma de programas e projetos considerados vitais para a organizacão, e direcionados para o alcance de objetivos, metas e de padrões de desempenho que sejam capazes de mensurar e avaliar, ao longo da realização do plano, o impacto das ações nos resultados desejados para a organização, em termos do cumprimento da missão e da visão de futuro. O balanced scorecard - BSC é uma dessas ferramentas de gestão que foi utilizada tanto no âmbito setorial quanto no nível corporativo da Câmara dos Deputados.

Para una relectura del compromiso en los años sesenta: paradoja, escritura transparente, retracción de Antonio Gamoneda

[ES] En este artículo se trata de analizar el planteamiento del compromiso poético a la altura del comienzo de la década de los años sesenta, a partir del análisis de esa modalidad de escritura en Blues castellano de Antonio Gamoneda, libro cuyos poemas datan de 1961–1966, aunque permaneció inédito hasta 1982. Leído en el contexto de su producción, Blues castellano muestra una solidaridad absoluta con algunos de los modelos poéticos comprometidos de la época (Nazim Hikmet, Bertolt Brecht, los espirituales negros, etc.), así como una vinculación hacia un tipo de compromiso poético que va a hacer recaer su dimensión crítica en el lenguaje poético, no sólo en el referente externo. En Blues castellano se consolidan ya algunos de los conceptos centrales de la poesía gamonediana posterior: retracción, búsqueda de una escritura transparente, desaparición del sujeto en la escritura, etc.

Experimental Study on Surface Deformation and Surface Wave of Fluid Convection with Free Surface

An optical diagnostic system consisting of Michelson interferometer with image processor has been developed for study of the kinetics of thermal capillary convection and buoyancy convection. This optical interferometer has been used to observe and measure surface deformation and surface wave of capillary convection and buoyancy convection in a rectangular cavity with different temperature’s sidewalls. Fourier transformation is used to image processing. The quantitative results of surface deformation and surface wave have been calculated from the interference fringe pattern. With the increasing of temperature gradient, the liquid surface slant gradually. It’s deformation has been calculated, which is related directly with temperature gradient. This is one of the characters introducing convection. Another interesting phenomenon is the inclining direction, which is different when the liquid layer is thin or thick. When the liquid layer is thin, convection is mainly controlled by thermocapillary effect. However, When the liquid layer is thick, convection is mainly controlled by buoyancy effect. Surface deformation in the present experiment are more and more declining in this process. The present experiment proved that surface deformation appears before the appearance of surface wave on fluid convection, it is related with temperature gradient, and the height of liquid layer, and lies on capillary convection and buoyancy convection. The present experiment also demonstrates that the amplitude of surface wave of thermocapillary-buoyancy convection is much smaller than surface deformation, the wave is covered by deformation.

A view of the Assessment and Feedback Landscape: baseline analysis of policy and practice from the JISC Assessment and Feedback programme

Assessment and feedback lies at the heart of the learning experience, and forms a significant part of both academic and administrative workload. It remains however the single biggest source of student dissatisfaction with the higher education experience. The JISC Assessment and Feedback programme (Sept 2011-Aug 2014) is supporting large-scale changes in assessment and feedback practice, supported by technology, with the aim of enhancing the learning and teaching process and delivering efficiencies and quality improvements. This report summarises baseline reviews undertaken by a number of institutions as part of their programme activity.
