Reflexiones sobre la calidad de la carrera de medicina en México
de la Garza-Aguilar, Javier;
Gaceta médica de México , 2005,
Abstract: introduction: at the end of the xxth century, collegiate efforts (evaluation and accreditation) were carried out to identify the quality of undergraduate medical education in mexico. the growth of medical schools during the 1970s had stabilized and the combination of other factors had contributed to increase its quality. material and methods: analytic descriptive research of selected indicators of the medical curricula from the sixties to the year 2000: entry, enrollment, and drop out rates, graduates, title, selection by the national postgraduate exam of medical residences (enarm), faculty members and creation of medical schools. statistical analysis included χ2 and t tests. results: in the seventies the number of medical schools doubled and the country increased its entry by 400%, enrollment by 700% and the number of graduates by 600%. the drop out rates and title efficiencies remained stable with averages of 76.2 and 76.4%, respectively; the first one that reflects the efficiency of the educational system, was not different in the period studied, when student's t-test (p < 0.01) was used. in the nineties, entry, enrollment and graduates increased again by 300, 400 and 700%, compared with the seventies. one out of every two graduates was selected by the enarm in 1991 and in 2001, one out of six. conclusions: the growth in enrollment and graduates once again, stands in contrast with the drop out rate that has remained stable. this suggests that the country has not increased significantly the quality of its medical education. the latter could be verified for each institution with the indicators used in the present study and by the assessment and accreditation of the programs.
El papel de la dimensión simbólico-estética en los actuales procesos de reconstrucción identitaria frente a la globalización cultural
Ullán de la Rosa, F. Javier
Revista de Dialectología y Tradiciones Populares , 2001,
Abstract: The new concept of the glocal has come into being as an identity of synthesis by which peoples as diverse as the Black communities on both sides of the Atlantic, the Ticuna Indians in the Upper Amazon Basin and the Basque nationalists in Europe assert and reconstruct their self as they deal with the invasion of the global into their lives. The author argues that this synthesis between the global and the local takes place in many cases by means of a dichotomy: whereas the global takes control of the infrastructural, socio-political and ethic-axiological levels of culture and leads societies toward uniformization, the local remains at the formal, aesthetic level of symbols and icons, shaping self-referred, de-socialized differential identities. En lo que respecta a la dimensión cultural de la globalización, aparece el nuevo concepto de lo glocal , un mecanismo de identidad de síntesis a través del cual grupos tan diferentes como las comunidades negras de ambos lados del Atlántico, los indios ticuna del Alto Amazonas o los nacionalistas vascos en Europa reafirman sus sentimientos de pertenencia, reconstruyéndolos ante la invasión de lo global en sus vidas. Este artículo sostiene la hipótesis de que la síntesis entre lo global y lo local está realizándose en muchos lugares por medio de la siguiente dicotomía: mientras lo global toma posesión de los niveles infraestructural, socio-político y ético-axiológico de la cultura, conduciendo a las sociedades hacia una cierta uniformización, lo local permanece en el nivel formal y estético de los símbolos e iconos, dando forma a identidades diferenciales auto-referenciales y desocializadas.
Revista Psicogente , 2009,
Abstract: In social institutions, among other things, it is possible to learn different skills to relate with the others. So, we may suppose within School, several sceneries are generated so that students achieve skills to establish a relationship with their partners as well with other people. These skills may be noted by good or bad treatments.We think intentional formation/bringing up in emotional intelligence would be important in the construction of pacific coexistence sceneries in Schools. All of this due to the fact students would achieve skills to process emotional information, letting them to prepare for the display of socio-affective competences. Together with these, students would relate since the practice of the good care, peaceful solution of conflicts, equity and the other’s legitimacy, essential elements in the citizen formation, coexistence, respect and promotion of fundamental rights.
La naturaleza milenarista del discurso indianista latinoamericano. Analizando las contradicciones entre discurso y praxis
Javier Ullán de la Rosa
Culturales , 2008,
Abstract: En este artículo se analiza el discurso ideológico de los principales movimientos indianistas de América Latina desvelando sus analogías con las ideologías milenaristas y su necesaria contradicción con la praxis política. Se trata de argumentar, a la luz de la ecología humana, por qué es imposible llevar a la práctica los programas ideológicos indianistas. Se concluye que la principal funcionalidad de este discurso es psicosocial, como estrategia para movilizar a las masas. Por último, el artículo avanza como receta política para los pueblos indígenas del continente una tercera vía, que sea viable y evite los dos extremos, la asimilación total y el nativismo conservador de tendencias milenaristas, de estos movimientos.
Biomechanical Signals Human-Computer Interface for Severe Motor Disabilities  [PDF]
Albano Carrera, Alonso A. Alonso, Ramón de la Rosa, Javier M. Aguiar
E-Health Telecommunication Systems and Networks (ETSN) , 2013, DOI: 10.4236/etsn.2013.24009
Abstract: A system that allows computer interaction by disabled people with very low mobility and who cannot use the standard procedure based on keyboard and mouse is presented. The development device uses the patient’s voluntary biomechanical signals, specifically, winkswhich constitute an ability that generally remains in this kind of patients—, as interface to control the computer. A prototype based on robust and low-cost elements has been built and its performance has been validated through real trials by 16 users without previous training. The system can be optimized after a learning period in order to be adapted to every user. Also, good results were obtained in a subjective satisfaction survey that was completed by the users after carrying out the test trials.
Analysis of Contributions to NO2 Ambient Air Quality Levels in Madrid City (Spain) through Modeling. Implications for the Development of Policies and Air Quality Monitoring  [PDF]
Rafael Borge, David de la Paz, Julio Lumbreras, Javier Pérez, Michel Vedrenne
Journal of Geoscience and Environment Protection (GEP) , 2014, DOI: 10.4236/gep.2014.21002

As environmental standards become more stringent (e.g. European Directive 2008/50/EC), more reliable and sophisticated modeling tools are needed to simulate measures and plans that may effectively tackle air quality exceedances, common in large cities across Europe, particularly for NO2. Modeling air quality in urban areas is rather complex since observed concentration values are a consequence of the interaction of multiple sources and processes that involve a wide range of spatial and temporal scales. Besides a consistent and robust multi-scale modeling system, comprehensive and flexible emission inventories are needed. This paper discusses the application of the WRF-SMOKE-CMAQ system to the Madrid city (Spain) to assess the contribution of the main emitting sectors in the region. A detailed emission inventory was compiled for this purpose. This inventory relies on bottom-up methods for the most important sources. It is coupled with the regional traffic model and it makes use of an extensive database of industrial, commercial and residential combustion plants. Less relevant sources are downscaled from national or regional inventories. This paper reports the methodology and main results of the source apportionment study performed to understand the origin of pollution (main sectors and geographical areas) and define clear targets for the abatement strategy. Finally the structure of the air quality monitoring is analyzed and discussed to identify options to improve the monitoring strategy not only in the Madrid city but the whole metropolitan area.

Effectiveness of Improved Cookstoves to Reduce Indoor Air Pollution in Developing Countries. The Case of the Cassamance Natural Subregion, Western Africa  [PDF]

The Spanish NGO “Alianza por la Solidaridad” has installed improved cookstoves in 3000 households during 2012 and 2013 to improve energy efficiency reducing fuelwood consumption and to improve indoor air quality. The type of cookstoves were Noflaye Jeeg and Noflaye Jaboot and were installed in the Cassamance Natural Subregion covering part of Senegal, The Gambia and Guinea-Bissau. The Technical University of Madrid (UPM) has conducted a field study on a sample of these households to assess the effect of improved cookstoves on kitchen air quality. Measurements of carbon monoxide (CO) and fine particle matter (PM2.5) were taken for 24-hr period before and after the installation of improved cookstoves. The 24-hr mean CO concentrations were lower than the World Health Organization (WHO) guidelines for Guinea-Bissau but higher for Senegal and Gambia, even after the installation of improved cookstoves. As for PM2.5 concentrations, 24-hr mean were always higher than these guidelines. However, improved cookstoves produced significant reductions on 24-hr mean CO and PM2.5 concentrations in Senegal and for mean and maximum PM2.5 concentration on Gambia. Although this variability needs to be explained by further research to determine which other factors could affect indoor air pollution, the study provided a better understanding of the problem and envisaged alternatives to be implemented in future phases of the NGO project.

Slow dynamics in a turbulent von Kármán swirling flow
Alberto de la Torre,Javier Burguete
Physics , 2007, DOI: 10.1103/PhysRevLett.99.054101
Abstract: We present an experimental study of a turbulent von K\'arm\'an flow produced in a cylindrical container using two propellers. The mean flow is stationary up to $Re = 10^4$, where a bifurcation takes place. The new regime breaks some symmetries of the problem, and is time-dependent. The axisymmetry is broken by the presence of equatorial vortices with a precession movement, being the velocity of the vortices proportional to the Reynolds number. The reflection symmetry through the equatorial plane is broken, and the shear layer of the mean flow appears displaced from the equator. These two facts appear simultaneously. In the exact counterrotating case, a bistable regime appears between both mirrored solutions and spontaneous reversals of the azimuthal velocity are registered. This evolution can be explained using a three-well potential model with additive noise. A regime of forced periodic response is observed when a very weak input signal is applied.
Dynamical properties of the Landau-Ginzburg model with long-range correlated quenched impurities
Elka Korutcheva,F. Javier de la Rubia
Physics , 1998, DOI: 10.1103/PhysRevB.58.5153
Abstract: We investigate the critical dynamics of the time-dependent Landau-Ginzburg model with non conserved n-component order parameter (Model A) in the presence of long-range correlated quenched impurities. We use a special kind of long-range correlations, previously introduced by Weinrib and Halperin. Using a double expansion in \epsilon and \delta we calculate the critical exponent z up to second order on the small parameters. We show that the quenched impurities of this kind affect the critical dynamics already in first order of \epsilon and \delta, leading to a relevant correction for the mean field value of the exponent z
