El levantamiento del velo en la doctrina y la jurisprudencia ecuatoriana

La persona jurídica es un centro de imputación diferenciado, en el cual se limita la responsabilidad patrimonial de quienes se asocian. sin embargo, a veces esta figura puede ser mal utilizada para alcanzar metas prohibidas por la ley o para perjudicar a terceros. La legislación ha previsto mecanismos para evitar esta utilización indebida de la persona jurídica, pero, excepcionalmente, se dan casos en que la solución legislativa no es suficiente, por lo que, partiendo de los principios generales del derecho de la buena fe, la lealtad y la equidad, la jurisprudencia ha desestimado la personalidad jurídica y ha llegado hasta quienes, amparándose en la figura societaria, han pretendido burlar la ley o abusar del derecho. Se ha desarrollado la teoría del regard of legal entity, que recibe muchos nombres en español (se ha preferido el de levantamiento del velo) que permite al juez, excepcionalmente, levantar el velo que separa al espectador de la realidad, a fin de imponer a los responsables del fraude o el abuso, la responsabilidad que les corresponda. en primer lugar se hace una breve exposición de la teoría, reseñando lo que han dicho los autores, para continuar examinando la situación ecuatoriana, las disposiciones legales aplicables y las sentencias en las cuales los jueces se han referido a esta teoría, y concluir señalando la naturaleza procesal de la figura, la inconveniencia de dictar una ley que la incorpore al ordenamiento jurídico y el riesgo de una utilización masiva e indiscriminada.

Roberto Arlt, la nación y su angustiosa trayectoria (Dossier: Literaturas de la integración, el Sur y su diversidad)

En las primeras décadas del siglo XX, la Argentina sufrió un desajuste económico y social respecto del plan estratégico de 1880. Los acontecimientos históricos rompieron el modelo de la prosperidad infinita y pusieron de manifiesto la disolución del ser nacional en revueltas militares, fraude electoral, corrupción, caudillismo y brechas profundas entre regiones y clases sociales. Hacia 1930, la escritura de Roberto Artl se presenta como un cuestionamiento acerca de los límites del proyecto modernizador y de las instancias más significativas del mandato de progreso histórico. Los personajes de sus ficciones le permiten al escritor proyectar una interpretación no solo de su ser caído y angustiado, sino también del sujeto desligado de aquella sociabilidad propuesta por la generación de los románticos y que en 1880 parecía determinar una identidad estable, según reglas aparentemente seguras. El escritor posee la visión de que 1930 es el momento histórico que exige otro estatuto de lo real. El efecto de lectura de la obra de Arlt reside en la manipulación indefinida del lenguaje literario a través de la propuesta de personajes anclados en la percepción de un mundo que los excluye y de una peripecia narrativa que devela la descentración de la Historia como relato total. Consecuentemente, su eficacia es impactar y movilizar el cuerpo social a través de la producción imaginaria como una versión literaria de la Historia.

Performance and prediction: Bayesian modelling of fallible choice in chess

Evaluating agents in decision-making applications requires assessing their skill and predicting their behaviour. Both are well developed in Poker-like situations, but less so in more complex game and model domains. This paper addresses both tasks by using Bayesian inference in a benchmark space of reference agents. The concepts are explained and demonstrated using the game of chess but the model applies generically to any domain with quantifiable options and fallible choice. Demonstration applications address questions frequently asked by the chess community regarding the stability of the rating scale, the comparison of players of different eras and/or leagues, and controversial incidents possibly involving fraud. The last include alleged under-performance, fabrication of tournament results, and clandestine use of computer advice during competition. Beyond the model world of games, the aim is to improve fallible human performance in complex, high-value tasks.

A survey of terahertz applications in cultural heritage conservation science

The authors present a review of the advances that have been made to establish terahertz applications in the cultural heritage conservation sector over the last several years. This includes material spectroscopy, 2D and 3D imaging and tomographic studies, using a broad range of terahertz sources demonstrating the breadth and application of this burgeoning community.

Skilloscopy: Bayesian modeling of decision makers' skill

This paper proposes and demonstrates an approach, Skilloscopy, to the assessment of decision makers. In an increasingly sophisticated, connected and information-rich world, decision making is becoming both more important and more difficult. At the same time, modelling decision-making on computers is becoming more feasible and of interest, partly because the information-input to those decisions is increasingly on record. The aims of Skilloscopy are to rate and rank decision makers in a domain relative to each other: the aims do not include an analysis of why a decision is wrong or suboptimal, nor the modelling of the underlying cognitive process of making the decisions. In the proposed method a decision-maker is characterised by a probability distribution of their competence in choosing among quantifiable alternatives. This probability distribution is derived by classic Bayesian inference from a combination of prior belief and the evidence of the decisions. Thus, decision-makers’ skills may be better compared, rated and ranked. The proposed method is applied and evaluated in the gamedomain of Chess. A large set of games by players across a broad range of the World Chess Federation (FIDE) Elo ratings has been used to infer the distribution of players’ rating directly from the moves they play rather than from game outcomes. Demonstration applications address questions frequently asked by the Chess community regarding the stability of the Elo rating scale, the comparison of players of different eras and/or leagues, and controversial incidents possibly involving fraud. The method of Skilloscopy may be applied in any decision domain where the value of the decision-options can be quantified.

Sub-surface terahertz imaging through uneven surfaces: visualizing Neolithic wall paintings in Çatalhöyük

Pulsed terahertz imaging is being developed as a technique to image obscured mural paintings. Due to significant advances in terahertz technology, portable systems are now capable of operating in unregulated environments and this has prompted their use on archaeological excavations. August 2011 saw the first use of pulsed terahertz imaging at the archaeological site of Çatalhöyük, Turkey, where mural paintings dating from the Neolithic period are continuously being uncovered by archaeologists. In these particular paintings the paint is applied onto an uneven surface, and then covered by an equally uneven surface. Traditional terahertz data analysis has proven unsuccessful at sub-surface imaging of these paintings due to the effect of these uneven surfaces. For the first time, an image processing technique is presented, based around Gaussian beam-mode coupling, which enables the visualization of the obscured painting.

Terahertz deconvolution

The ability to retrieve information from different layers within a stratified sample using terahertz pulsed reflection imaging and spectroscopy has traditionally been resolution limited by the pulse width available. In this paper, a deconvolution algorithm is presented which circumvents this resolution limit, enabling deep sub-wavelength and sub-pulse width depth resolution. The algorithm is explained through theoretical investigation, and demonstrated by reconstructing signals reflected from boundaries in stratified materials that cannot be resolved directly from the unprocessed time-domain reflection signal. Furthermore, the deconvolution technique has been used to recreate sub-surface images from a stratified sample: imaging the reverse side of a piece of paper.
