Teacher education/miseducation? Thoughts and laments of two sceptic theachers
La base de este trabajo consiste en un estudio analítico, dentro de lo posible, de la formación del maestro-a desde tres elementos fundamentales e interdependientes cuales son el institucional, el curricular y el legislativo. La historia es nuestro principal testigo y la realidad actual corrobora vivencias pasadas y presentes. Sin caer en pesimismos ni derrotismos tratamos de dejar bien reflejada que la formación del maestro-a es a la vez, paradójicamente, deformación y que ambos paradigmas han convivido y conviven en la actualidad.This work is based on an analytical study of the teachers’ education
from three fundamental and interdependent points of view: the institutional, the
curricular and the legislative one. History is our main witness and present reality
corroborates past and present experiences. Without falling into pessimism or
defeatism, we try to reflect properly that teacher education is at the same time and,
paradoxically, miseducation, and that both paradigms coexist today and have done
so/coexisted in the past

Neuronal nuclear tau and neurodegeneration
Tau is a well-known microtubule-associated protein related to its cytoplasmic localization in a neuronal cell. However, tau has been located at the cell nucleus where it could be a nucleic acid-associated protein by its preferential binding to DNA sequences present in the nucleolus and pericentromeric heterochromatin. This less well-known localization of tau could not be trivial, since during aging, an increase in the amount of nuclear tau takes place and it may be related to the described role of tau in the activation of transposons and further aging accelerationWork in the laboratory of JA is funded by grants from the Spanish Ministry of Economy and Competitiveness (PGC-2018-09177-B-100).

Azcondo, "Pre-calculated duty cycle control implemented in FPGA for power factor correction", 35th Annual Conference of IEEE Industrial Electronics, 2009. IECON '09, Porto (Portugal), 2009, pp. 2955 - 2960A power factor correction (PFC) technique based on pre-calculated duty cycle values is presented in this paper. In this method the duty ratios for half a line period are calculated in advance and stored in a memory. By synchronizing the memory with the line, near unity power factors can be achieved in a specific operating point. The main advantage of this technique is that neither current measurement nor current loop are needed. To obtain stable output voltages a voltage loop is included. A boost converter prototype controlled by an FPGA evaluation board has been implemented in order to verify the functionality of the proposed method. Both the simulation and experimental results show that near unity power factor can be achieved with this PFC strategy
Sistema de tareas profesionales para la preparación didáctica del entrenador de béisbol
El avance científico-técnico en el Béisbol propicia transformaciones a nivel internacional, en los modos de concebir las clases de los alumnos, en los implementos deportivos, los procedimientos, etapas de preparación y los objetivos técnicos del deporte a cumplir en cada una de estas, en este sentido la preparación del entrenador ocupa un lugar importante dentro de los cambios y transformaciones que puedan surgir en la esfera deportiva. De ahí que la investigación que se presenta parte de determinar las insuficiencias que se manifiestan en la labor didáctica del entrenador que labora con lanzadores de Béisbol de la categoría sub-12 años de iniciación deportiva. Su solución tiene lugar a partir de considerar la didáctica como recurso importante para lograr una mejor preparación en el entrenador, por medio de la aplicación de un sistema de tareas profesionales. Los resultados obtenidos demuestran, por un lado, las brechas teóricas existentes en la atención a la didáctica en la esfera deportiva y por otro la inexistencia de propuestas consecuentes con las necesidades profesionales del entrenador, la aplicación del pre-experimento realizado por medio del pretest y el postest corrobora la factibilidad del sistema de tareas. A manera de conclusión se constatan las insuficientes propuestas que posibiliten el perfeccionamiento del modo de actuación del entrenador de Béisbol en la iniciación deportiva.PALABRAS CLAVE: preparación didáctica; sistema de tareas profesionales; practica reflexiva; iniciación deportiva; lanzadores de Béisbol.System of professional tasks for the didactic preparation of the baseball coachABSTRACTThe scientific-technical advance in Baseball fosters transformations at the international level, in the ways of conceiving the classes of the students, in the sports equipment, the procedures, preparation stages and the technical objectives of the sport to be fulfilled in each of these, In this sense, the preparation of the coach occupies an important place within the changes and transformations that may arise in the sporting sphere. Hence, the research that is presented starts from determining the shortcomings that are manifested in the didactic work of the coach who works with baseball pitchers of the category under 12 years of sports initiation. Its solution takes place from considering didactics as an important resource to achieve a better preparation in the coach, through the application of a system of professional tasks. The results obtained demonstrate, on the one hand, the existing theoretical gaps in the attention to didactics in the sports sphere and, on the other, the inexistence of proposals consistent with the professional needs of the coach, the application of the pre-experiment carried out through the pretest and the posttest confirms the feasibility of the task system. By way of conclusion, the insufficient proposals that make it possible to improve the mode of action of the Baseball coach in sports initiation are noted.KEYWORDS: didactic preparation; professional task system; reflective practice; sports initiation; Baseball pitchers
Más allá de la docencia: la unidad de atención psicológica y salud mental del universitario (UAPSMU) en la Universidad de Salamanca (1996-2004)
College Mental Health Counselling is a specialized service offered in several Spanish Universities some decades ago. Salamanca University is between the pioneers to offer university community a specialized service of Psychological Aid and First Intervention on Mental Health within their own campus, for a population group characterized by rootlessness of their family environment, usually far from their home environment, and with an age between 18 and 25, a period with life crises and severe pathological onsets. In this paper some data on the history of this Unit in Salamanca University is offered, from the beginning of the service in 1996 to their change in 2003. The service was free-cost, only for university people, and the professional staff included professors and professional psychologists under a scheme of non-profit collaborations. The main indicators of the interventions and people attended during this period are exposed, and also the main intervention programs developed: Facing Exams Anxiety; Care on rootlessness from family environment and attachment problems, between others. Finally we made some considerations on the structure and objectives for this type of services.ResumenLa Atención Psicológica al Universitario se ofrece como un Servicio especializado en algunas Universidades españolas desde hace dos décadas. La Universidad de Salamanca está entre las pioneras en ofertar a la comunidad universitaria un servicio específico de atención psicológica y primera intervención en salud mental en su propio entorno, a un grupo poblacional definido principalmente por el desarraigo de su domicilio familiar, ya que una elevada proporción de su alumnado procede de otras comunidades, a veces muy distantes, así como por las características del propio tramo etario de los jóvenes universitarios, entre 18 y 25 años, un momento de eclosión, tanto de crisis vitales evolutivas, como de patologías graves. En este trabajo se ofrecen datos sobre la historia de esta Unidad en la Universidad de Salamanca, desde su puesta en marcha en el año 1996, hasta su reformulación en 2004. El servicio fue de carácter gratuito y exclusivo para todos los miembros de la comunidad universitaria. La atención fue desarrollada mediante un equipo de psicólogos y profesores que colaboraron con carácter voluntario y gratuito. Se analiza la demanda atendida en este período, y se detallan los principales programas de intervención desarrollados: Enfrentamiento de la ansiedad ante los exámenes e Intervención ante la problemática del desarraigo, entre otros. Finalmente se hacen una serie de consideraciones sobre la organización y objetivos de este tipo de servicios.AbstractCollege Mental Health Counselling is a specialized service offered in several Spanish Universities some decades ago.

La caracterización de estructuras bucales de los géneros Carollia y Rhinophyla como medio para determinar asociaciones con la vegetación en bosque secundario de Leticia kilómetro 11 y Puerto Nariño.
This article is the compilation of the work that was carried out in the vicinity of Kilometer 11 (Leticia) and Puerto Nariño, Amazonas, this consisted of the characterization of the floristic constitution of the mentioned localities, by means of 50m x 2m plots, in order to properly locate fog nets for the capture of bats and subsequent identification of eating habits and interactions with plants, thanks to the observation of their oral structures. After two days of capture and observation, photographic and written material was recorded, together with bibliographic review, allowed to establish the frugivorous habits of the captured bats, found in the bibliography consulted as Dosel mammals; With the accompaniment of local guides and bibliography, it was evidenced that it´s main source of food is Yarumo (Cecropia peltata) that due to it´s height between 5m and 30m high is characterized in Dosel (Linares, 2010) and the Chontaduro (Bactris gasipaes) that can reach a height of 20m, (Mesa, 2013), these are abundant plants in the characterization of secondary forest, this allowed to show bats interactions with these plants, since they can act as dispersers of seeds in the Colombian Amazon rainforest. (Harris, R & Hutchison, 1998).El presente artículo es el compilado del trabajo realizado en inmediaciones del Kilómetro 11 (Leticia) y Puerto Nariño, Amazonas, el cual consistió en la caracterización de la constitución florística de las localidades mencionadas, por medio de parcelas de 50m x 2m, con el fin de ubicar adecuadamente redes de niebla para la captura de murciélagos y posterior identificación de hábitos alimenticios e interacciones con plantas, dadas por la observación de sus estructuras bucales. Tras dos días de captura y observación, se registró material fotográfico y escrito, que en compañía de revisión bibliográfica, permitieron establecer los hábitos frugívoros de los murciélagos capturados, encontrados en la bibliografía consultada como mamíferos de dosel; con el acompañamiento de guías locales y bibliografía, se evidencio que su principal fuente de alimento es el Yarumo (Cecropia peltata) que debido a su altura entre 5m y 30m de altura se caracteriza en Dosel (Linares, 2010), y el Chontaduro (Bactris gasipaes) que puede llegar a medir 20m de altura, (Mesa, 2013), estas son plantas abundantes en la caracterización de bosque secundario, esto permitió evidenciar interacciones de los murciélagos con dichas plantas, ya que pueden actuar como dispersores de semillas en la selva Amazónica Colombiana (Harris, R & Hutchison, 1998)
