Impacto de la Sociedad del Conocimiento en la universidad y en la comunicación científica

2014

A la largo de las dos últimas décadas y como resultado de la introducción y uso intensivo de las tecnologías de la información y del conocimiento en general y de internet en particular, la universidad esta viviendo un proceso de transformación complejo que afecta a sus estructuras académicas y organizativas así como también a su concepción de metodología docente. Las TIC han evidenciado la necesidad de establecer estrategias de coherencia institucional en su uso y aplicación, así como la posibilidad de ampliar los ámbitos de acción institucional y el acceso masivo a la formación superior. Y todo ello pone de manifiesto el cambio existente de un modelo de formación basado en la transmisión d…

Consequences of the disorders socio-policies on the Central African education system of 1991 to the year 2001: situation of primary education teaching

2006

This work deals about the impacts both on supply and demand of education emerging from socio-political instability and trouble, the Sub Saharan geographical context. The targeted goal is to present a comparative analysis which indicates that countries could attain objective in the development of education if the context for civil peace appear satisfied. Then, by a historical and socio-political step, the study in the evolution of the school since its creation in the Central Africa case shows that multiple factors impacted within time duration the development of education. Lastly, the analysis of the consequences of the disorders encountered in the since the beginning of the Nineties reveals…

Technical Note: Prediction Models of Airborne Sound Insulation of Multilayer Materials with Viscoelastic Thin Sheets

2008

The growing introduction of new insulation materials in building acoustics has caused an increase of the importance of the prediction tools. Appropriate simulations allow strictly necessary laboratory measurements to be identified. In this way, costs are reduced. The demands of new legislation has resulted in the appearance of various software designed to facilitate prediction. The prediction models are based on different hypotheses: adaptation of impedances, spatial behaviour of spectral components, statistical energy distribution, the Finite Element Method (FEM), etc. Each of these models and methods offer advantages and contain limitations. In this paper, different models for prediction…

Avoiding accidents at the champagne reception: A study of joint lifting and balancing

2017

Using a lifting and balancing task, we contrasted two alternative views of planning joint actions: one postulating that joint action involves distinct predictions for self and other, the other postulating that joint action involves coordinated plans between the coactors and reuse of bimanual models. We compared compensatory movements required to keep a tray balanced when 2 participants lifted glasses from each other’s trays at the same time (simultaneous joint action) and when they took turns lifting (sequential joint action). Compared with sequential joint action, simultaneous joint action made it easier to keep the tray balanced. Thus, in keeping with the view that bimanual models are reu…

Evaluación de las actitudes de culpabilización de la víctima en casos de violencia de pareja contra la mujer: desarrollo y validación de la escala VB…

2018

ABSTRACT Intimate partner violence against women (IPVAW) is the most common form of violence suffered by women and constitutes a serious public health problem of global proportions. Public attitudes towards IPVAW are key to understanding the social context in which this type of violence occurs. Victim-blaming attitudes are among those that reflect public tolerance and acceptability of IPVAW and are often used to explain or justify IPVAW. In this study we develop and validate a new instrument to assess victim-blaming attitudes in cases of IPVAW. A sample of 1,800 participants was recruited through social media and a second sample of 50 IPVAW offenders was used for validation purposes. Throug…

Model Predictive Control for Shunt Active Filters With Fixed Switching Frequency

2016

This paper presents a modification to the classical Model Predictive Control algorithm, named Modulated Model Predictive Control, and its application to active power filters. The proposed control is able to retain all the advantages of a Finite Control Set Model Predictive Control whilst improving the generated waveforms harmonic spectrum. In fact a modulation algorithm, based on the cost function ratio for different output vectors, is inherently included in the MPC. The cost function-based modulator is introduced and its effectiveness on reducing the current ripple is demonstrated. The presented solution provides an effective and straightforward single loop controller, maintaining an excel…

Extended X-ray emission in PKS 1718-649

2018

PKS 1718$-$649 is one of the closest and most comprehensively studied candidates of a young active galactic nucleus (AGN) that is still embedded in its optical host galaxy. The compact radio structure, with a maximal extent of a few parsecs, makes it a member of the group of compact symmetric objects (CSO). Its environment imposes a turnover of the radio synchrotron spectrum towards lower frequencies, also classifying PKS 1718$-$649 as gigahertz-peaked radio spectrum (GPS) source. Its close proximity has allowed the first detection of extended X-ray emission in a GPS/CSO source with Chandra that is for the most part unrelated to nuclear feedback. However, not much is known about the nature …
