Prácticas pedagógicas universitarias: reflexiones sobre vincularidad

This article is presented from the research project Education and Subjectivity:the practices, the curriculum, the knowledge, and the relationships in the productionof subjectivity from the Faculty of Human Sciences, Universidad Nacional de San Luis,in which we have been investigating multiple articulations, dimensions, and relationshipsbetween education and subjectivity.In this work we try to explore the links between teachers and students in thepedagogical practices in health careers of a public university, from some concepts ofrelational psychoanalysis that allow us to think about and analyze the creation ofrelationships between subjects. We start from considering that relationships place theSelf in the situation of having to do the necessary transformations at the presence ofanother, or to pretend that the other becomes absent, disappears, or its specificity iserased.From the analysis of a set of interviews with teachers, we share some observationsabout teachers and students relationships in pedagogical practices and the psychologicalburden involved by being with another: the vicissitudes of somebody's presence andthe creation of differences while trying to blur the Otherness.Keywords: teacher-student relationship, teaching practice.Este artículo se presenta en el marco del proyecto de investigación Educación y Subjetividad: las prácticas, el currículum, los saberes y los vínculos en laproducción de subjetividad, Proico 4-1518, radicado en la Facultad de Ciencias Humanas de la Universidad Nacional de San Luis, desde el que indagamos múltiples articulaciones, dimensiones y relaciones entre el campo de la educación y la subjetividad,donde inscribimos nuestro pensamiento en las lógicas de lo múltiple.En este trabajo intentamos explorar los vínculos entre docentes y estudiantes en lasprácticas pedagógicas en carreras de salud de una universidad pública, desde algunosconceptos del psicoanálisis vincular que permiten pensar y analizar la producción derelaciones entre los sujetos.

A Review of Artificial Intelligence in the Internet of Things

Humankind has the ability of learning new things automatically due to the capacities with which we were born. We simply need to have experiences, read, study… live. For these processes, we are capable of acquiring new abilities or modifying those we already have. Another ability we possess is the faculty of thinking, imagine, create our own ideas, and dream. Nevertheless, what occurs when we extrapolate this to machines? Machines can learn. We can teach them. In the last years, considerable advances have been done and we have seen cars that can recognise pedestrians or other cars, systems that distinguish animals, and even, how some artificial intelligences have been able to dream, paint, and compose music by themselves. Despite this, the doubt is the following: Can machines think? Or, in other words, could a machine which is talking to a person and is situated in another room make them believe they are talking with another human? This is a doubt that has been present since Alan Mathison Turing contemplated it and it has not been resolved yet. In this article, we will show the beginnings of what is known as Artificial Intelligence and some branches of it such as Machine Learning, Computer Vision, Fuzzy Logic, and Natural Language Processing. We will talk about each of them, their concepts, how they work, and the related work on the Internet of Things fields

Characterization and classification of Spanish paprika (Capsicum annuum L.) by liquid chromatography coupled to electrochemical detection with screen-printed carbon-based nanomaterials electrodes

Screen-printed electrodes based on graphite, carbon nanotubes, carbon nanofibers, and graphene were tested as amperometric detectors for the determination of polyphenols by high performance liquid chromatography (HPLC). The chromatographic performance as well as the obtained sensitivity, detection and quantification limits suggest that carbon nanofibers modified screen-printed electrode (SPCE-CNF) is the amperometric sensor that provides the best analytical performance. Upon this confirmation, chromatographic data obtained using SPCE-CNF were exploited by means of linear discriminant analysis to successfully characterize and classify 96 Spanish paprika (Capsicum annuum L.) samples with protected designation of origin: from La Vera (including sweet, bittersweet and spicy types) and from Murcia (including sweet and spicy types)

The “DrownSafe” project: assessing the feasibility of a puppet show in teaching drowning prevention to children and parents

Drowning remains a prominent global pediatric health concern, necessitating preventive measures such as educational initiatives for children and caregivers. In this study, we aimed to assess the feasibility and educational effectiveness of an interactive puppet show centered on teaching water safety to children and parents. A 30 min original theater performance, featuring two actors and three puppets (a girl, a crab, and a lifeguard), was conducted. Subsequently, 185 children (aged 4 to 8) and their 160 parents (134 mothers and 26 fathers) participated in this quasi-experimental study. Pre- and post-show tests were administered to evaluate knowledge and behaviors regarding aquatic environments. Prior to the puppet show, 78% of the children exhibited basic aquatic competency. Only 33% considered swimming alone risky. Following the intervention, 81.6% of the children changed their perception of the risks of solo beach activities, showing improved knowledge regarding contacting an emergency number (from 63.2% to 98.9%, p < 0.001). The intervention increased parents’ intention to visit lifeguard-patrolled beaches and improved their CPR knowledge with regard to drowning victims by 58.8%. In conclusion, a drowning prevention puppet show positively impacted children and parents, potentially enhancing safety behaviors during water-related leisure activities, warranting its consideration part of comprehensive drowning prevention strategies.Universidade de Vig

Validation of Spanish Language Evaluation Instruments for Body Dysmorphic Disorder and the Dysmorphic Concern Construct

Dysmorphic concern (DC) refers to excessive preoccupation with a slight or imagined defect in physical appearance with social avoidance and behavior directed at controlling the defect in appearance. This study attempted to adapt the factor structure of two instruments that cover the DC construct, the Dysmorphic Concern Questionnaire (DCQ) and the Body Dysmorphic Disorder Examination Self-Report (BDDE-SR), to Spanish and establish their psychometric properties. A total of 920 subjects (62.7% women, Mage = 32.44 years) participated. Exploratory and Confirmatory Factor Analysis of both scales found adequate goodness of fit indices. A one-dimensional structure was found for the DCQ and two first-order factors (dissatisfaction/preoccupation with body image (BI) and BI avoidance behavior) were identified for the BDDE-SR. The psychometric test–retest reliability and validity properties (content, convergent, and discriminant) were satisfactory. It is suggested that the DC construct includes both cognitive and behavioral aspects and may represent a continuum of severity with Body Dysmorphic Disorder at the end.European Union’s Seventh Framework Programme for research, technological development and demonstration under [grant agreement no 31674

Distinct disease-sensitive GABAergic neurons in the perirhinal cortex of Alzheimer's mice and patients

Neuronal loss is the best neuropathological substrate that correlates with cortical atrophy and dementia in Alzheimer’s disease (AD). Defective GABAergic neuronal functions may lead to cortical network hyperactivity and aberrant neuronal oscilla-tions and in consequence, generate a detrimental alteration in memory processes. In this study, using immunohistochemical and stereological approaches, we report that the two major and non-overlapping groups of inhibitory interneurons (SOM-cells and PV-cells) displayed distinct vulnerability in the perirhinal cortex of APP/PS1 mice and AD patients. SOM-positive neurons were notably sensitive and exhibited a dramatic decrease in the perirhinal cortex of 6-month-old transgenic mice (57% and 61% in areas 36 and 35, respectively) and, most importantly, in AD patients (91% in Braak V–VI cases). In addition, this interneuron degenerative process seems to occur in parallel, and closely related, with the progression of the amyloid pathol-ogy. However, the population expressing PV was unaffected in APP/PS1 mice while in AD brains suffered a pronounced and significant loss (69%). As a key component of cortico-hippocampal networks, the perirhinal cortex plays an important role in memory processes, especially in familiarity-based memory recognition. Therefore, disrupted functional connectivity of this cortical region, as a result of the early SOM and PV neurodegeneration, might contribute to the altered brain rhythms and cognitive failures observed in the initial clinical phase of AD patients. Finally, these findings highlight the failure of amyloidogenic AD models to fully recapitulate the selective neuronal degeneration occurring in humans.Instituto de Salud Carlos III (ISCiii) de España y fondos FEDER de la Unión Europea.

El papel de la autoconciencia en la preocupación por la imagen corporal en población general

Antecedentes: La autoconciencia se contempla de manera dicotómica; por un lado, como un estado transitorio inducido por estímulos contextuales y por otro, como una predisposición del individuo a focalizar su atención sobre aspectos internos o externos. Hay estudios que señalan que las personas con alta autoconciencia pública se preocupan en mayor medida por cómo son percibidas por los demás y, consecuentemente, realizan conductas que según ellas, atenúan las valoraciones negativas por parte de otros. Objetivo. Se pretende estudiar el papel que tiene la autoconciencia y sus dimensiones (privada, pública y ansiedad social) en la preocupación por la imagen corporal. Se predice que tanto la autoconciencia pública, como la privada y la ansiedad social, tienen un peso importante en la preocupación por el cuerpo, especialmente entre las mujeres. Método: La muestra la componen 475 participantes de ambos sexos (307 mujeres y 168 hombres) con edades comprendidas entre 18 y 65 años (Media=37,85 y DT=13,37). ara la evaluación se utilizó el Dysmorphic Concern Questionnaire (DCQ Cuestionario de preocupaciones dismórficas) y Self-Consciousness Scale - Revised (SCS-R Escala de Autoconciencia). Se empleó un diseño transversal (una medida) para un método relacional. Ancova de la Autoconciencia (teniendo en cuenta sus tres componentes), preocupación dismórfica, edad y género. Resultados: Se obtienen relaciones significativas entre las preocupaciones dismórficas y la autoconciencia, tanto globalmente como por factores. Se obtiene un patrón diferenciado para estos criterios en función del género y la edad. Conclusiones: La identificación de los niveles de autoconciencia asociados a la preocupación por la imagen corporal puede ser relevante para la salud física y psicológica por su repercusión en el trastorno dismórfico corporal.Background: Self-consciousness, is contemplated dichotomously; on the one hand, as a transitory state induced by contextual stimuli and secondly, as a predisposition of the individual to focus attention on internal or external aspects. Studies show that people with high public self-consciousness are concerned more by how they are perceived by others and consequently perform behaviors that, according to them, attenuate the negative evaluations by others. Objective : The aim is to study the role of the self - consciousness and its dimensions (private, public and social anxiety) in concern with body image. It is predicted that both public self - consciousness, and private and social anxiety, have an important role in the body concern, particularly in women. Method: 475 male and female participants (307 women and 168 men) aged between 18 and 65 years (average = 37,85 and SD = 13,37). For the evaluation used the Dysmorphic concern questionnaire (DCQ) and Self - Consciousness Scale (SCS-R). Background: Self-consciousness, is contemplated dichotomously; on the one hand, as a transitory state induced by contextual stimuli and secondly, as a predisposition of the individual to focus attention on internal or external aspects. Studies show that people with high public self-consciousness are concerned more by how they are perceived by others and consequently perform behaviors that, according to them, attenuate the negative evaluations by others

Phagocytic clearance of presynaptic dystrophies by reactive astrocytes in Alzheimer's disease

Reactive astrogliosis, a complex process characterized by cell hypertrophy and upregulation ofcomponents of intermediate filaments, is a common feature in brains of Alzheimer’s patients. Reac-tive astrocytes are found in close association with neuritic plaques; however, the precise role ofthese glial cells in disease pathogenesis is unknown. In this study, using immunohistochemical tech-niques and light and electron microscopy, we report that plaque-associated reactive astrocytesenwrap, engulf and may digest presynaptic dystrophies in the hippocampus of amyloid precursorprotein/presenilin-1 (APP/PS1) mice. Microglia, the brain phagocytic population, was apparentlynot engaged in this clearance. Phagocytic reactive astrocytes were present in 35% and 67% ofamyloid plaques at 6 and 12 months of age, respectively. The proportion of engulfed dystrophicneurites was low, around 7% of total dystrophies around plaques at both ages. This fact, alongwith the accumulation of dystrophic neurites during disease course, suggests that the efficiency ofthe astrocyte phagocytic process might be limited or impaired. Reactive astrocytes surroundingand engulfing dystrophic neurites were also detected in the hippocampus of Alzheimer’spatientsby confocal and ultrastructural analysis. We posit that the phagocytic activity of reactive astrocytesmight contribute to clear dysfunctional synapses or synaptic debris, thereby restoring impairedneural circuits and reducing the inflammatory impact of damaged neuronal parts and/or limitingthe amyloid pathology. Therefore, potentiation of the phagocytic properties of reactive astrocytesmay represent a potential therapy in Alzheimer s disease.Fondo de Investigación Sanitaria (FIS).

Introducción breve a la ingeniería dirigida por modelos

The software crisis is a concept that has started to be used in 1968, at the first conference organized by the North Atlantic Treaty Organization (NATO) on software development. There, Edsger Dijkstra criticized that projects were not completed in compliance with the classic triple constraint of project management (scope, time and cost), since most of them do not reach the expected requirements, are delivered out of time or exceeds the expected cost. Unfortunately, the current reality is that while there have been proposed new methodologies aimed at solving the usual problems related to software development, there is still no reliable method to estimate the development of computer systems. This work introduces the Model-Driven Engineering approach that, according to the experts, will help to solve many of the problems that thousands of software development teams have daily worldwide.La crisis del software es un concepto que comenzó a utilizarse en 1968, en la primera conferencia organizada por la Organización del Tratado del Atlántico Norte (OTAN) en el desarrollo de software. Allí, Edsger Dijkstra criticó que los proyectos no se completaban debido a la clásica triple restricción de la gestión de proyectos —alcance, tiempo y costo—, ya que la mayoría de ellos no alcanzaban los requisitos previstos, se entregaban fuera de plazo o superaban el costo esperado. Por desgracia, la realidad actual es que; si bien se han propuesto nuevas metodologías destinadas a la solución de los problemas habituales relacionados con el desarrollo de software, todavía no existe un método fiable para estimar el desarrollo de los sistemas informáticos. En este artículo se presenta el enfoque de Ingeniería Dirigida por Modelos que, según los expertos, ayudará a resolver muchos de los problemas que miles de equipos de desarrollo de software tienen a diario en todo el mundo
