Identificación de indicadores propios de estudiantes de talento matemático : fluidez, flexibilidad, originalidad, elaboración y creatividad
2021
Título, resumen, palabras clave en español e ingles Resumen basado en el de la publicación Se describen los resultados de un estudio exploratorio cuyo objetivo es identificar características de estudiantes de talento matemático cuando se enfrentan a una secuencia de problemas de solución múltiple. Para ello, se han seleccionado dos muestras de alumnos : una formada por estudiantes de entre 15 y 17 años participantes en un programa dirigido a estudiantes con talento matemático, y la otra formada por alumnos con una sólida formación matemática. A continuación, se ha diseñado una secuencia de cuatro tareas de resolución múltiple y se ha realizado un análisis cualitativo de las respuestas con e…
Fallas demográficas y rendimiento de los equipos de trabajo: El papel mediador del conflicto, el afecto negativo, y la reflexividad grupal
2015
Los equipos son un elemento clave en las organizaciones debido, al menos en parte, a los distintos trabajos que informan de las relaciones positivas entre el trabajo basado en equipos y la calidad de los productos y servicios ofrecidos por una organización (Gibson, Porath, Benson y Lawler, 2007). Al mismo tiempo que las organizaciones, debido a las razones prácticas señaladas, han incrementado sus experiencias en la utilización de equipos, los equipos en las organizaciones han visto incrementada su diversidad (Jackson, Joshi, & Erhardt, 2003; Triandis, Kurowski & Gelfand, 1994; Williams & O¿Reilly, 1998). La globalización de los negocios, el aumento en la incorporación de la mujer y las min…
Muscle function in monozygotic female twin pairs discordant for hormone replacement therapy
2011
Introduction: Postmenopausal monozygotic twin pairs discordant for hormone replacement therapy (HRT) provide an advantageous study design controlling for genetic background for elucidating the relationships between aging, sex hormone levels, muscle strength, contractile capacity, and fatigability. Methods: Thirteen postmenopausal monozygotic twin pairs discordant for HRT were measured for maximal voluntary torque (MVC) and twitch characteristics using electrical stimulation before and after intermittent dynamic plantarflexor exercise until exhaustion. Results: Peak twitch torque was 32% higher in HRT users than in their non-HRT, genetically identical sisters (P = 0.002), but MVC did not dif…
Localizing Global Solidarity: Humanitarian Aid in Lesvos
2021
The so-called “refugee crisis” in Lesvos, Greece provides a poignant example of situated, local suffering that has called for the coordination of global resources to provide relief. Some of the first to respond were local and international Citizen Initiatives for Global Solidarity (CIGS). While a growing role for CIGS has been interpreted as a call for more global involvement, arguments for the increased localization of relief efforts suggest the need for aid agents to maintain a reflexive awareness of the potential for an influx of outside assistance to disempower those most affected. We argue that barriers to implementing the localization of humanitarian aid can be better understood by po…
Sagittal Plane Hip, Knee, and Ankle Biomechanics and the Risk of Anterior Cruciate Ligament Injury: A Prospective Study
2018
Background: Stiff landings with less knee flexion and high vertical ground-reaction forces have been shown to be associated with an increased risk of anterior cruciate ligament (ACL) injury. The literature on the association between other sagittal plane measures and the risk of ACL injuries with a prospective study design is lacking. Purpose: To investigate the relationship between selected sagittal plane hip, knee, and ankle biomechanics and the risk of ACL injury in young female team-sport athletes. Study Design: Case-control study; Level of evidence, 3. Methods: A total of 171 female basketball and floorball athletes (age range, 12-21 years) participated in a vertical drop jump test usin…
The Emotional Self: A Relational View (El sujeto emocional: un punto de vista relacional)
2023
Emotions are experiences that connect us to others in deep and meaningful ways, however, there is something about them that makes them, at the same time, the most intimate of our experiences. The way in which I understand the latter departs from the notions of privacy or interiority which are central to the debate on the asymmetry between the first and the third person. The notion of intimacy to which I allude here is linked, rather, to the experience of being vulnerable. As is well known, we can only feel an emotion for something we care about and, in this sense, every emotional experience is an experience in which we are exposed, that is, in which there is something at stake for us. From …
Synthesis of Monodisperse Spherical Nanocrystals
2016
Nanoparticles, small units of matter with dimensions in the range 1-100 nm, exhibit many advantageous size-dependent magnetic, electrical, chemical and optical prop- erties, which are not observed at the microscale or bulk. These properties are extremely sensitive to particle size, and thus the ability to produce monodisperse particles is critical. Due to its ease of use and flexibility, precipitation of nanoparticles from solution is one of the most widely used synthesis methods. The main disadvantage of this method is that the relationship between particle growth and system conditions is not fully understood. In practice, the optimal reaction conditions are usually ascertained empirically…
FLUMO: FLexible Underwater MOdem
2019
The last years have seen a growing interest in underwater acoustic communications because of its applications in marine research, oceanography, marine commercial operations, the offshore oil industry and defense. High-speed communication in the underwater acoustic channel has been challenging because of limited bandwidth, extended multipath, refractive properties of the medium, severe fading, rapid time variation and large Doppler shifts. In this paper, we show an implementation of a flexible Software-Defined Acoustic (SDA) underwater modem, where modulation parameters are completely tunable to optimize performance. In particular, we develop the system architecture following two key ideas. …
Pensiero e autocoscienza. Lo strano anello della cognizione umana.
L’argomento centrale della tesi è la natura della mente umana in relazione alla questione dell’intricato rapporto fra pensiero e autocoscienza. La congettura fondamentale consiste, in primo luogo, nel sostenere che particolari proprietà del pensiero umano, la flessibilità e la fluidità, rappresentino le caratteristiche salienti e specifiche della cognizione umana e, in secondo luogo, nel rilevare che il costituirsi di queste ultime sia strettamente connesso al fenomeno di autocoscienza. Il fuoco dell’analisi ruota attorno a tre importanti nuclei tematici: cosa si intende per flessibilità e fluidità della mente? Cosa si intende per autocoscienza – o meglio – quale tipo di autocoscienza esatt…
Efecto en la mejora de la amplitud articular y flexibilidad tras un programa de entrenamiento de fuerza en la tercera edad
2017
“EFECTO EN LA MEJORA DE LA AMPLITUD ARTICULAR Y FLEXIBILIDAD TRAS UN PROGRAMA DE ENTRENAMIENTO DE FUERZA EN LA TERCERA EDAD” INTRODUCCIÓN La esperanza de vida ha experimentado un considerable aumento en los últimos años, de tal forma que la población cada vez alcanza edades más avanzadas. Debido a ello, se brindan oportunidades para que el adulto mayor AM), pueda disfrutar y participar de forma activa en la sociedad. Debido a que este colectivo es cada vez más importante y el peso creciente que tiene en la sociedad, sus especificidades son motivo para que sea objeto de estudio.
