Lieux de culte dans l'Est de la Gaule : la place des sanctuaires dans la cité

2009

International audience; “Incubo”, an inventory of places of worship in ancient Burgundy, deals with the territories of Lingons and Éduens. This inventory already includes approximately one hundred completed index cards intended for publication. Three sites are presented here: an administrative city center, Autun (Saône-et-Loire), and two secondary cities, Vertault (Côte-d’Or) and Pierre-de-Bresse (Saône-et-Loire). These cases are representative of the different types of places of worship found in the region under investigation, but also of the various documentary states on which our inventory is based. Our object is to illustrate the potential of the Burgundian corpus and to evoke some prob…

El pensamiento espontáneo docente sobre la ciencia y su enseñanza

2018

<span>En las dos últimas décadas la investigación en didáctica de las ciencias ha centrado su atención en el aprendizaje y, en particular, se ha caracterizado por haber estudiado en profundidad el conocimiento inicial de los estudiantes en muy diversos dominios de las ciencias. Desde hace pocos años el énfasis está derivado -y cada vez con mayor interés- hacia el estudio de la enseñanza y, en particular, hacia el de su principal artífice: el profesorado.</span>

Sostenibilidad y laboratorios escolares

2018

<span>Actualmente no es ninguna exageración afirmar que estamos viviendo una situación de verdadera emergencia planetaria, marcada por toda una serie de graves problemas estrechamente relacionados entre sí, tales como: superpoblación, contaminación, agotamiento de recursos naturales, cambio climático, pérdida de biodiversidad, lluvia ácida y destrucción de la capa de ozono. Dichos problemas, lejos de disminuir, son cada vez más intensos y extienden su impacto sobre todo el planeta. Así, en cuanto al calentamiento global, se afirma que la gravedad es tal, que si no se pone freno antes de una decena de años, después será ya demasiado tarde (Gore, 2007).</span>

La motivación de los estudiantes y la enseñanza de la Química. Una cuestión controvertida

2018

<span>El tema de la motivación de los estudiantes hacia el aprendizaje de cualquier materia científica constituye una seria preocupación para el profesorado. En primer lugar, porque los docentes constatan una falta general de interés de los alumnos hacia las disciplinas científicas como la Física y la Química. Esta percepción ha sido corroborada por los propios estudiantes en diferentes trabajos de investigación. En efecto, los propios estudiantes señalan como principales causantes de su actitud desfavorable, de su desinterés hacia la ciencia y su aprendizaje, a la enseñanza de una ciencia descontextualizada...</span>

Dificultades para la incorporación a la enseñanza de los hallazgos de la investigación e innovación en didáctica de las ciencias

2018

<span>La importancia social concedida, desde hace ya décadas, a la educación científica (Dewey 1916; Langevin, 1926) ha ido creciendo y ha experimentado, últimamente, un cambio cualitativo. En efecto, la tradicional importancia concedida a las inversiones en educación científica y tecnológica, para hacer posible el desarrollo futuro de un país, ha dejado paso al convencimiento de que la alfabetización científica de todos los ciudadanos y ciudadanas ha pasado a constituir una exigencia urgente, un requisito también para el desarrollo inmediato.</span>

Elucidating the Influence of the Activation Energy on Reaction Rates by Simulations Based on a Simple Particle Model

2020

An application for visualizing the dynamic properties of an equimolar binary mixture of isotropic reactive particles is presented. By introducing a user selectable choice for the activation energy, the application is useful to demonstrate qualitatively that the reaction rate depends on the above choice and on temperature. The application is based on a 2D realistic dynamic model where atoms move because of their thermal energies and the trajectories are determined by solving numerically Newton’s laws according to a Molecular Dynamics (MD) scheme. Collisions are monitored as time progresses, and every time the collision energy is larger than the selected activation energy, a reactive event oc…

Transnational bodies: Embodiment of transnational settings

2016

AbstractThe everyday life of more and more people is characterized by transnationalism. People increasingly interact across borders and in a network of transnational relationships. While interactions may be border-crossing, the actors’ body remains situated and limited in time and space. However, the thesis of this paper is that transnationalism processes are embodied. Thus, we speak of an embodiment of transnational settings. We focus on symbolic interactionism – Charles H. Cooley and George H. Mead in particular provide a large repertoire of concepts – to theoretically conceive transnational bodies. To show how transnational embodiment can manifest itself we use the example of young peopl…

Superiority of Optimized Portfolios to Naive Diversification: Fact or Fiction?

2017

Abstract DeMiguel, Garlappi, and Uppal (2009) conducted a highly influential study where they demonstrated that none of the optimized portfolios consistently outperformed the naive diversification. This result triggered a heated debate within the academic community on whether portfolio optimization adds value. Nowadays several studies claim to defend the value of portfolio optimization. The commonality in all these studies is that various portfolio optimization methods are implemented using the datasets generously provided by Kenneth French and the performance is measured by means of the Sharpe ratio. This paper aims to provide a cautionary note regarding the use of Kenneth French datasets …

Optimal Dynamic Portfolio Risk Management

2016

Numerous econometric studies report that financial asset volatilities and correlations are time-varying and predictable. Over the past decade, this knowledge has stimulated increasing interest in various dynamic portfolio risk control techniques. The two basic types of risk control techniques are: risk control across assets and risk control over time. At present, the two types of risk control techniques are not implemented simultaneously. There has been surprisingly little theoretical study of optimal dynamic portfolio risk management. In this paper, the author fills this gap in the literature by formulating and solving the multi-period portfolio choice problem. In terms of dynamic portfoli…
