Construcción antropológica de las prácticas alimentarias y su comprensión filosófico-moral: aportes sobre el reconocimiento recíproco y las patologías sociales de Axel Honneth

El artículo que se presenta forma parte de los productos derivados del proyecto de investigación auspiciado por el Programa de Mejoramiento del Profesorado (PROMEP-SEP/103.5712/8048), denominado: “Imaginario social sobre la corporeidad en alumnas y alumnos universitarios.” Agradecemos a la Secretaría de Educación Pública, a la Universidad Autónoma del Estado de México y a los integrantes y colaboradores del CA “Biopsicología, Salud y Sociedad” por su invaluable soporte. El trabajo está dedicado a la memoria de David Moisés Macedo, becario del proyecto y que desafortunadamente, falleciera durante el proceso de investigación, descansa en paz.En la época actual, donde el acto de alimentarse remite en gran parte a una ausencia de sentido de lo nutricio, se hace emergente mirar de nueva cuenta la importancia de resignificar tan relevante acontecimiento, desde los aspectos socioculturales más profundos y engastados en determinantes antropológicos y filosófico-morales que dotan a las prácticas alimentarias y sus diversos imaginarios de un sinfín de paradojas y correspondencias. En esta intención, planteamos una revisión teórica que aperture de nueva cuenta, la relación sustancial entre la corporeidad, la alimentación y sus imaginarios sociales en un contexto social cada vez más inestable. Se propone una comprensión de la problemática a partir de la teoría del reconocimiento recíproco y las patologías sociales desarrollada por Axel Honneth, para definir la dirección de las posibles intervenciones alimentarias. Abstract: Currently, where the act of feeding is based largely in a lack of nurturing sense, it is necessary to look back to the importance of giving a new perspective to such event, since the deepest and sociocultural aspects set into anthropological and moral Philosophy determinants which provide to the feeding practices and its several social imaginaries, endless paradoxes and correspondence. In this intention, we propose a theoretical review which apertures once again, the substantial relationship between embodiment, feeding and its social imaginaries in an increasingly unstable social context. It is proposed a problem comprehension since the reciprocal recognition and the social pathologies developed by Axel Honneth, in order to define the direction of possible feeding interference.Programa de Mejoramiento del Profesorado (PROMEP-SEP/103.5712/8048).

Effects of audio compression in automatic detection of voice pathologies

This paper investigates the performance of an automatic system for voice pathology detection when the voice samples have been compressed in MP3 format and different binary rates (160, 96, 64, 48, 24, and 8 kb/s). The detectors employ cepstral and noise measurements, along with their derivatives, to characterize the voice signals. The classification is performed using Gaussian mixtures models and support vector machines. The results between the different proposed detectors are compared by means of detector error tradeoff (DET) and receiver operating characteristic (ROC) curves, concluding that there are no significant differences in the performance of the detector when the binary rates of the compressed data are above 64 kb/s. This has useful applications in telemedicine, reducing the storage space of voice recordings or transmitting them over narrow-band communications channels

Storytelling y animación digital: usando cortos animados para la divulgación histórica y patrimonio cultural de la ciudad de Popayán

The Storytelling or narration of stories or facts has evolved from mere oral narration to sophisticated audiovisual products that use technologies for the development of video games, in this case the unity software is used as a support base for animated content. This article shows the creation of an animatedshort focused on the dissemination of the history of Popayán Cauca; the need arises to promote cultural identity, safeguard the tangible and intangible heritage of the region aligned with historical-experience tourism. In this sense, digital animation is used for digital reconstruction and as a didactic means to reach the public through digital platforms and function as a teaching tool. On the other hand, it is important to show the workflow of a digital production of this scope, which goes beyond the technical aspects and includes historical research, pre-production, production and post-production processes.El Storytelling o narración de cuentos o hechos ha evolucionado desde la mera narración oral hasta productos audiovisuales sofisticados que emplean tecnologías para el desarrollo de videojuegos, en este caso se emplea el software unity como base de soporte para el contenido animado. En el presente artículo se muestra la creación de un corto animado con enfoque a la divulgación historia de Popayán Cauca; la necesidad surge de promover la identidad cultural, salvaguardar el patrimonio material e inmaterial de la región alineado el turismo de experiencia-histórica. En ese sentido la animación digital es empleada para la reconstrucción digital y como medio didáctico para alcanzar el público a través de plataformas digitales y funcionar como herramienta de enseñanza.

However, the deployment of independent SDN controllers for core and metro segments can bring large inefficiencies to this core network reconfiguration based on traffic prediction when traffic flows from metro areas are rerouted to different ingress nodes in the core. In such cases, OD traffic patterns in the core might severely change, thus affecting the quality of the predictive OD models. New traffic model re-estimation usually takes a long time, during which no predictive capabilities are available for the network operator. To alleviate this problem, we propose to extend data analytics to metro networks to obtain predictive models for the metro flows; by knowing how these flows are aggregated into OD pairs in the core, we can also aggregate their predictive models, thus accurately predicting OD traffic and therefore enabling core VNT reconfiguration. To obtain quality metro-flow models, we propose an estimation algorithmthat processes monitored data and returns a predictive model. In addition, a flow controller is proposed for the control architecture to allow metro and core controllers to exchange metro-flow model information. The proposed model aggregation is evaluated through exhaustive simulation, and eventually experimentally assessed together with the flow controller in a testbed connecting premises in CNIT (Pisa, Italy) and UPC (Barcelona, Spain).Peer ReviewedPostprint (author's final draft

Unzipping the Secrets of Amyloid Disassembly by the Human Disaggregase

Neurodegenerative diseases (NDs) are increasingly positioned as leading causes of global deaths. The accelerated aging of the population and its strong relationship with neurodegeneration forecast these pathologies as a huge global health problem in the upcoming years. In this scenario, there is an urgent need for understanding the basic molecular mechanisms associated with such diseases. A major molecular hallmark of most NDs is the accumulation of insoluble and toxic protein aggregates, known as amyloids, in extracellular or intracellular deposits. Here, we review the current knowledge on how molecular chaperones, and more specifically a ternary protein complex referred to as the human disaggregase, deals with amyloids. This machinery, composed of the constitutive Hsp70 (Hsc70), the class B J-protein DnaJB1 and the nucleotide exchange factor Apg2 (Hsp110), disassembles amyloids of α-synuclein implicated in Parkinson’s disease as well as of other disease-associated proteins such as tau and huntingtin. We highlight recent studies that have led to the dissection of the mechanism used by this chaperone system to perform its disaggregase activity. We also discuss whether this chaperone-mediated disassembly mechanism could be used to solubilize other amyloidogenic substrates. Finally, we evaluate the implications of the chaperone system in amyloid clearance and associated toxicity, which could be critical for the development of new therapies.This research was funded by MCI/AEI/FEDER, UE (grant PID2019-111068GB-I00) and by the Basque Government (grant IT1201-19).

Assessment of regional pulmonary blood flow using Ga-68-DOTA PET

Background: In vivo determination of regional pulmonary blood flow (PBF) is a valuable tool for the evaluation of many lung diseases. In this study, the use of Ga-68-DOTA PET for the in vivo quantitative determination of regional PBF is proposed. This methodology was implemented and tested in healthy pigs and validated using fluorescent microspheres. The study was performed on young large white pigs (n = 4). To assess the reproducibility and consistency of the method, three PET scans were obtained for each animal. Each radiotracer injection was performed simultaneously to the injection of fluorescent microspheres. PBF images were generated applying a two-compartment exchange model over the dynamic PET images. PET and microspheres values were compared by regression analysis and Bland-Altman plot. Results: The capability of the proposed technique to produce 3D regional PBF images was demonstrated. The correlation evaluation between Ga-68-DOTA PET and microspheres showed a good and significant correlation (r = 0.74, P < 0.001). Conclusions: Assessment of PBF with the proposed technique allows combining the high quantitative accuracy of PET imaging with the use of Ga-68/Ge-68 generators. Thus, Ga-68-DOTA PET emerges as a potential inexpensive method for measuring PBF in clinical settings with an extended use.This work was supported by a grant from the Spanish Ministry of Economy and Competitiveness (MINECO) (SAF2014-58920-R) and a grant from the Carlos III Institute of Health (FIS-FEDER PI14-01427).

La autoevaluación de la práctica docente como herramienta para la mejora del proceso de enseñanza y aprendizaje del alumnado

After a brief historical review leading us to understand where the focus has been placed to improve education over the course of recent years, we reach the present, in which several reports and studies emphasize the influences on what happens in the classroom, ie in the interaction between teacher and students. The autonomy of schools should necessarily be linked to self-assessment to meet the objective of improving the students' learning. In this sense, teacher self-evaluation has to be a strategy that allows for the improvement of the school in general, as well as a process of continuous and collective professional development. From this perspective a proposal is presented (modeled on Intervention in Key Factors&nbsp; by the Educational Inspection of Andalusia) aimed at generating reflection at various levels (coordinating bodies, teachers, ...) regarding key factors such as curricula and evaluation, to assess in this way if this happens daily in class and to assure that the planning and the actual teaching in the classroom is adapted to the true needs of the students.Tras un breve recorrido histórico que nos lleva a conocer dónde se ha situado el foco para mejorar la educación a lo largo de los últimos años, se llega al momento actual en el que desde diversas instancias y estudios se hace hincapié en incidir en lo que ocurre en el aula, en la interacción entre docente y alumnado. La autonomía de los centros debe vincularse necesariamente a la autoevaluación para responder al objetivo de mejora de los aprendizajes del alumnado. En este sentido, la autoevaluación docente ha de ser una estrategia que permita la generalización de la mejora en el centro educativo, como un proceso de desarrollo profesional continuo y colectivo. Desde esta perspectiva se ofrece una propuesta (inspirada en el modelo de Intervención en Factores Clave de la Inspección Educativa de Andalucía) orientada a generar reflexión a varios niveles (órganos de coordinación, docentes,...) en torno a factores clave como curriculum y evaluación, y valorar así si lo que se hace diariamente en clase, y que tiene que ver con la planificación y la propia práctica docente en el aula, se adapta a las necesidades reales del alumnado

Estimación del sexo a partir del diámetro de la cabeza humeral y femoral en poblaciones mexicanas de época prehispánica y contemporánea

In bioarchaeology and forensic anthropology the most reliable skeletal element for sex estimation is the pelvis; nevertheless, when it is missing, other postcranial elements must be used. The main goal of this research is to provide sectioning points for sex assessment from humeral and femoral head diameters for three prehispanic and two contemporary Mexican populations. Using a sliding caliper, a total of 386 (45.3% female and 54.6% male) humeral and femoral head diameters were recorded. The sectioning point was calculated as the mean between sexes, and univariate independent sample t-tests were performed to test significant differences between sexes. The results demonstrate significant sexual differences in all populations and high percentages of correct sex classification (90%-94%). We conclude that the proposed cut-off points can be used as an alternative for sex estimation in Mexican populations, in contexts with incomplete skeletons and/or fragmented bones.Tanto en bioarqueología como en antropología forense, la pelvis es el elemento óseo con mayor confiabilidad para la estimación sexual; no obstante, cuando no está presente, otros elementos deben ser utilizados. Es por ello que el objetivo principal de este trabajo es proveer puntos de corte para estimar el sexo a partir del diámetro de la cabeza del húmero y del fémur, en poblaciones mexicanas (tres prehispánicas y dos contemporáneas). Utilizando el compás de corredera, se midió un total de 386 (45,3% femeninos y 54.6% masculinos) diámetros de la cabeza humeral y femoral. Los resultados demuestran diferencias estadísticamente significativas entre sexos en todas las poblaciones y altos porcentajes de clasificación sexual correcta (90%-94%). Por lo tanto, concluimos que los puntos de corte propuestos pueden ser utilizados como una alternativa para la estimación sexual, para la población mexicana, en contextos con esqueletos incompletos y/o huesos fragmentados.Asociación de Antropología Biológica Argentin

Knowledge about contraceptive methods and sexual behavior in young university students.

Introducción: En México los embarazos no planificados se presentan entre 30% y 60% en adolescentes. Esta problemática permea a todos los grupos de la sociedad observándose aún en las universidades. La Universidad Autónoma del Estado de México ha realizado acciones preventivas; sin embargo, en cinco años, el número de embarazos en las estudiantes incrementó en un plantel de la zona oriente, por lo que se propuso evaluar el conocimiento sobre métodos de planificación familiar y conducta sexual que tienen los estudiantes universitarios. Metodología: Estudio cuantitativo transversal realizado en 2018. La muestra no probabilística estuvo integrada por 224 alumnos de ciencias sociales del nivel superior de la Universidad Autónoma del Estado de México, quienes dieron su consentimiento informado. Se les aplicó un cuestionario de 32 ítems a través del cual se evaluó conocimiento sobre métodos de planificación familiar y conductas sexuales que tenían. Resultados: 51% informaron recibir información sobre métodos de planificación familiar entre 13 y 17 años, proviniendo de su profesor(a). 69% de los estudiantes reportaron haber tenido relaciones sexuales; de los cuales 97% respondieron que antes de ingresar al nivel superior recibieron la información sobre métodos anticonceptivos. Actualmente 45% no utiliza algún método anticonceptivo, 49% declararon haber tenido sexo oral y 18% anal. 9% reportó tener relaciones sexuales bajo influencia de drogas. Conclusiones: Se realizó un acercamiento al conocimiento sobre métodos de planificación familiar y conducta sexual de los estudiantes, para diseñar e implementar un programa de salud sexual que prevenga infecciones de transmisión sexual y embarazos no planificados.Unplanned pregnancies in Mexico occur between 30 and 60 percent of the cases in adolescents. This problem permeates all groups in society being observed even in universities. Universidad Autónoma del Estado de Mexico has developed preventive actions, but in five years the number of pregnancies in students increased in one of its campuses in the western area, reason why it was proposed to evaluate the knowledge about family planning methods and sexual behavior that university students have. Methodology: Cross-sectional quantitative study conducted in 2018. The non-probability sample consisted of 224 students from the upper level of Universidad Autónoma del Estado de Mexico who gave their informed consent. A questionnaire of 32 items was applied, through which knowledge about family planning methods and sexual behaviors they had were evaluated. Results: 51% reported receiving information about family planning methods when they were 13 and 17 years old, coming from their teachers. 69% of the students reported having had sexual intercourse from whom 97% answered that they had received information about contraceptive methods before entering the upper level. Currently 45% do not use any contraception method, 49% reported having oral sex and 18% anal sex; 9% reported having sex under the influence of drugs. Conclusions: An approach was made to knowledge about family planning methods and sexual behavior of students, to design and implement a sexual health program that prevents sexually transmitted infections and unplanned pregnancies

Influencia del desarrollo urbano sobre el legado sostenible de los eventos deportivos internacionales

The purpose of this study is to identify the effects of the urban development legacy on the sustainable legacy (economic, sociocultural, environmental and sports) of international sports events. 292 surveys were applied to the direct stakeholders of the sporting events in Santiago de Cali- Colombia, using a questionnaire structured in five constructs and 28 items. Goodness of fit, composite reliability, discriminant validity and the proposed structural model were examined using the partial least squares (PLS-SEM) path modeling method in ADANCO software. The results indicate that the legacy of urban development has a significant influence on the economic (p=<.001), sociocultural (p=<.001), environmental (p=<.001) and sports (p=<.001) legacies.
