¿Discapacidad para aprender o discapacidad para enseñar?

La principal motivación para la realización de este trabajo deviene de mi propia experiencia como profesional en el área de la discapacidad, aunque no posea un titulo, no es desconocido, que en su mayoría, los estudiantes de Educación Física comenzamos a ejercer profesionalmente nuestra vocación sin ninguna certificación que acredite institucionalmente y nos habilite a ejercer esa función. Tuve mi primer acercamiento, profesionalmente hablando, muy temprano en mi carrera, antes de comenzar el tercer año, si bien en ese momento solo ejercía como de ayudante y no estuve a cargo del grupo en ningún momento, pude experimentar lo que es trabajar con alumnos con necesidades educativas especiales. El acercamiento desde el punto de vista profesional al área de la discapacidad, es en este sentido, más dificultoso que, por ejemplo a una colonia de vacaciones, ya que el miedo y el desconocimiento, sumados quizá a prejuicios sociales y culturales, dificultan este acercamiento. El punto en cuestión seria analizar si la preparación de los futuros docentes en Educación Física dentro del área de la discapacidad es suficiente o insuficiente, y si realmente es necesario que los planes de estudios de nuestra carrera posean una gran variedad de disciplinas o puede pensarse en una especialización temática de acuerdo a las necesidades y/o intereses de los estudiantes.Panel "Educación e inclusión social".Departamento de Educación Físic

Environmental effects on the photophysics of organic-inorganic halide perovskites

The photophysical properties of films of organic-inorganic lead halide perovskites under different ambient conditions are herein reported. We demonstrate that their luminescent properties are determined by the interplay between photoinduced activation and darkening processes, which strongly depend on the atmosphere surrounding the samples. We have isolated oxygen and moisture as the key elements in each process, activation and darkening, both of which involve the interaction with photogenerated carriers. These findings show that environmental factors play a key role in the performance of lead halide perovskites as efficient luminescent materials.Peer Reviewe

Collective action for innovation and small farmer market access: The Papa Andina experience

"The Andean highlands are home to some of the poorest rural households in South America. Native potato varieties and local knowledge for their cultivation and use are unique resources possessed by farmers in these areas. As the forces of globalization and market integration penetrate the Andes, they present both challenges and opportunities for farmers there. This paper reports on how the Papa Andina Regional Initiative is promoting the use of collective action to reduce poverty in the Andes, by developing market niches and adding value to potatoes, particularly the native potatoes grown by poor farmers. Since 1998, Papa Andina has worked with partners in Bolivia, Ecuador and Peru to stimulate pro-poor innovation within market chains for potato-based products. Market chain actors (including small-scale potato producers, traders, and processors), researchers, and other service providers have engaged in innovation processes via two principal tools for facilitating collective action: the Participatory Market Chain Approach (PMCA) and Stakeholder Platforms. The PMCA fosters commercial, technological, and institutional innovation through a structured process that builds interest, trust, and collaboration among participants. Stakeholder Platforms provide a space for potato producers, other market chain actors, and service providers to come together to identify their common interests, share knowledge, and develop joint activities. The PMCA and Stakeholder Platforms have empowered Andean potato farmers by expanding their knowledge of markets, market agents, and business opportunities. Social networks built up among producers, market agents, and service providers have stimulated commercial innovation, which in turn has stimulated technical and institutional innovation. These innovations have allowed small farmers to market their potatoes on more favorable terms and other market chain actors to increase their incomes. This paper describes experiences with collective action in Bolivia, Ecuador, and Peru, via the PMCA and Stakeholder Platforms. Based on these experiences, a number of lessons are formulated for using collective action to stimulate innovation, market access, and poverty reduction in other settings." authors' abstractCollective action, Small farmers, Potato, Participatory methods, Innovation, stakeholders, Markets,

Photophysical Analysis of the Formation of Organic–Inorganic Trihalide Perovskite Films: Identification and Characterization of Crystal Nucleation and Growth

In this work we demonstrate that the different processes occurring during hybrid organic–inorganic lead iodide perovskite film formation can be identified and analyzed by a combined in situ analysis of their photophysical and structural properties. Our observations indicate that this approach permits unambiguously identifying the crystal nucleation and growth regimes that lead to the final material having a cubic crystallographic phase, which stabilizes to the well-known tetragonal phase upon cooling to room temperature. Strong correlation between the dynamic and static photoemission results and the temperature-dependent X-ray diffraction data allows us to provide a description and to establish an approximate time scale for each one of the stages and their evolution. The combined characterization approach herein explored yields key information about the kinetics of the process, such as the link between the evolution of the defect density during film formation, revealed by a fluctuating photoluminescence quantum yield, and the gradual changes observed in the PbI2-related precursor structure.Unión Europea Seventh Framework Programme (FP7/2007-2013)/ERC Grant Agreement No. 307081 (POLIGHT)España, Ministerio de Economía y Competitividad Grants MAT2014- 54852-R and MAT2012-31659España, Comunidad de Madrid programme S2013/MIT-274

Germinación Y Crecimiento En Vivero Y En Campo De Zaya (Amoreuxia palmatifida DC.), Una Especie Nativa Amenazada En México

The food needs by the human population is increasing; In that sense, having a new crop can contribute to ameliorate the demand for food. The zaya (Amoreuxia palmatifida DC.) has been used as food both before and after the arrival of the European settlers in several states of northwest Mexico and southwestern United States. Over a hundred years ago there are authors recommending the zaya as a native plant with potential to be cultivated, being one of the problems to overcome the difficulty of its seeds to germinate. The study objectives were to evaluate germination treatments of zaya seeds and measure plantula grow under two systems. It was found that seeds physically scarified by sanding were those that germinated (73%; p <0.0001), compared to treatments control, of soaking for 24 hours and addition, of boiling water, were does not germinate any seed. The results of zaya growth were greater (p <0.0001), for plants in open field under drip irrigation, compared to the plants planted in pots under shadehouse, for all variables evaluated. The results obtained in this work, about the germination and growing of zaya, can be used to multiply their propagules and restore natural populations affected in northwest of Mexico. It is necessary to continue research on agronomic aspects of the zaya cultivation, a plant with great potential for both human and animal feeding, ornamental, and possibly medicinal use

Role of indistinguishability in interferometric phase estimation

We report a theoretical and experimental study on the role of indistinguishability in the estimation of an interferometric phase. In particular, we show that the quantum Fisher information, which limits the maximum precision achievable in the parameter estimation, increases linearly with respect to the degree of indistinguishability between the input photons in a two-port interferometer, in the ideal case of a pure probe state. We experimentally address the role played by the indistinguishability for the case of two photons entering a polarization-based interferometer, where the degree of indistinguishability is characterized by the overlap between two spatial modes. The experimental results support the fact that, even in the presence of white noise, a quantum enhancement in the interferometric phase estimation can be obtained from a minimum degree of indistinguishability.Fil: Knoll, Laura Tamara.
