Spanish Architecture 1992-2008

Architecture in Spain 1992-2008. This Conference (in image format) performs a synthetic tour of the architectural production in Spain during the period that opens with the events of 1992 (Olympics Games and World Expo in Seville) and closed in 2008 (exhibition of MoMA, Global Crisis and Universal Expo of Zaragoza). On the one hand shows the world and Spanish socio-economic context and is a selection of different architectures, grouped into six streams.

Competition for procurement shares

We propose a new procurement procedure that allocates shares of the total amount to be procured depending on the bids of suppliers. Among the properties of the mechanism are the following: (i) Bidders have an incentive to participate in the procurement procedure, as equilibrium payoffs are strictly positive. (ii) The mechanism allows variations in the extent to which affirmative action objectives, like promoting local industries, are pursued. (iii) Surprisingly, even while accomplishing affirmative action goals, procurement expenditures might be lower than under a standard auction format.

Web-based OERs in Computer Networks

Learning and teaching processes are continually changing. Therefore, design of learning technologies has gained interest in educators and educational institutions from secondary school to higher education. This paper describes the successfully use in education of social learning technologies and virtual laboratories designed by the authors, as well as videos developed by the students. These tools, combined with other open educational resources based on a blended-learning methodology, have been employed to teach the subject of Computer Networks. We have verified not only that the application of OERs into the learning process leads to a significantly improvement of the assessments, but also that the combination of several OERs enhances their effectiveness. These results are supported by, firstly, a study of both students’ opinion and students’ behaviour over five academic years, and, secondly, a correlation analysis between the use of OERs and the grades obtained by students.

imaxin|software: PLN aplicada a la mejora de la comunicación multilingüe de empresas e instituciones

imaxin|software es una empresa creada en 1997 por cuatro titulados en ingeniería informática cuyo objetivo ha sido el de desarrollar videojuegos multimedia educativos y procesamiento del lenguaje natural multilingüe. 17 años más tarde, hemos desarrollado recursos, herramientas y aplicaciones multilingües de referencia para diferentes lenguas: Portugués (Galicia, Portugal, Brasil, etc.), Español (España, Argentina, México, etc.), Inglés, Catalán y Francés. En este artículo haremos una descripción de aquellos principales hitos en relación a la incorporación de estas tecnologías PLN al sector industrial e institucional.

Lecciones aprendidas gamificando cuando aún no se llamaba gamificación

El término gamificación está de moda. Los gurús la sitúan como una tecnología emergente y disruptiva, que cambiará muchas de nuestras experiencias en campos tan alejados de los juegos como el empresarial, el marketing y la relación con los clientes. Y el entorno educativo no escapará a ello. En este artículo presentamos la experiencia de un grupo de profesores preocupados por la docencia, que llevamos años experimentando con los videojuegos y las experiencias lúdicas, y que de repente nos hemos encontrado con el término gamificación. Estas son las lecciones que hemos aprendido, que podemos enmarcar en el campo de la gamificación en educación, pero que derivan de una experiencia práctica, de un análisis desmenuzado y de una reflexión concienzuda. Pretendemos mostrar qué es lo realmente importante y qué puntos debemos tener en cuenta los profesores antes de lanzarnos al diseño gamificado de nuestra propuesta docente.

A Book of Accounts beginning Feb. 26 1791, 1791-1799

The marbled-hardcover book contains three sections: a two column debit and credit entry section for students and tutors, a list of "the Bills of the Senior Class calculated" for 1793 and 1794, and at the end of the volume a personal accounting of expenses from February 1797 through January 1799 kept by Shapleigh during the time he was Harvard's Librarian, for services including mending, wood hauling, and "To Miss Morie for cleaning windows & washing sheets," as well as purchases such as books, coffee, and theater tickets.

Benchmarking analogue models of brittle thrust wedges

We performed a quantitative comparison of brittle thrust wedge experiments to evaluate the variability among analogue models and to appraise the reproducibility and limits of model interpretation. Fifteen analogue modeling laboratories participated in this benchmark initiative. Each laboratory received a shipment of the same type of quartz and corundum sand and all laboratories adhered to a stringent model building protocol and used the same type of foil to cover base and sidewalls of the sandbox. Sieve structure, sifting height, filling rate, and details on off-scraping of excess sand followed prescribed procedures. Our analogue benchmark shows that even for simple plane-strain experiments with prescribed stringent model construction techniques, quantitative model results show variability, most notably for surface slope, thrust spacing and number of forward and backthrusts. One of the sources of the variability in model results is related to slight variations in how sand is deposited in the sandbox. Small changes in sifting height, sifting rate, and scraping will result in slightly heterogeneous material bulk densities, which will affect the mechanical properties of the sand, and will result in lateral and vertical differences in peak and boundary friction angles, as well as cohesion values once the model is constructed. Initial variations in basal friction are inferred to play the most important role in causing model variability. Our comparison shows that the human factor plays a decisive role, and even when one modeler repeats the same experiment, quantitative model results still show variability. Our observations highlight the limits of up-scaling quantitative analogue model results to nature or for making comparisons with numerical models. The frictional behavior of sand is highly sensitive to small variations in material state or experimental set-up, and hence, it will remain difficult to scale quantitative results such as number of thrusts, thrust spacing, and pop-up width from model to nature.
