La presencia del nietzscheanismo en la biopolítica contemporánea
2022
La filosofía de Nietzsche anticipó notablemente el umbral de la modernidad biológica al conceptualizar el alcance fisiológico de la moral, la política y la religión, así como su instrumentalización con fines de control social. El objetivo de este artículo es analizar el estímulo que ha representado la filosofía de Nietzsche para algunos de los principales pensadores de la cuestión biopolítica, en concreto, Michel Foucault, Roberto Esposito y Peter Sloterdijk, y desvelar en qué medida sus núcleos conceptuales convergen y divergen. La aportación concreta reside en señalar algunos de los vínculos que articulan el tema de la disciplina y la cría (Zucht und Züchtung) con la configuración de la b…
Ant Abundance along a Productivity Gradient: Addressing Two Conflicting Hypotheses
2015
The number of individuals within a population or community and their body size can be associated with changes in resource supply. While these relationships may provide a key to better understand the role of abiotic vs. biotic constraints in animal communities, little is known about the way size and abundance of organisms change along resource gradients. Here, we studied this interplay in ants, addressing two hypotheses with opposite predictions regarding variation in population densities along resource gradients- the 'productivity hypothesis' and the 'productivity-based thinning hypothesis'. The hypotheses were tested in two functional groups of ground-dwelling ants that are directly primar…
Análisis de una intervención educativa para el desarrollo de la autodeterminación en una alumna con síndrome de Down
2021
Resumen Antecedentes: uno de los mayores problemas a los que se enfrentan los jóvenes con discapacidad intelectual es su bajo nivel de autonomía. Objetivo: el objetivo de este trabajo es analizar la eficacia de una intervención basada en el uso de las tecnologías de la información y comunicación (TIC) para alcanzar mejoras en autodeterminación en una estudiante con síndrome de Down. Método: la intervención está basada en el diseño y aplicación de una página web diseñada teniendo en cuenta las necesidades específicas de la participante, su nivel de competencias, y sus intereses. Esta herramienta TIC permite a la estudiante trabajar de manera autónoma tres áreas de conocimiento distintas y ot…
Stochastic linearization of MDOF systems under parametric excitations
1992
Abstract The stochastic linearization approach is examined for non-linear systems subjected to parametric type excitations. It is shown that, for these systems too, stochastic linearization and Gaussian closure are two equivalent approaches if the former is applied to the coefficients of the Ito differential rule. A critical review of other stochastic linearization approaches is also presented and discussed by means of simple examples.
The Academic Background of Youth Soccer Coaches Modulates Their Behavior During Training
2020
This investigation aims to explore the relationship between the academic backgrounds of youth soccer coaches (U10 and U12 age groups) in Spain and the type of verbal behavior used during training sessions. The sample consisted of 70 coaches divided into two groups, depending on whether or not they had engaged with a university-level academic studies related to Physical Education and or Sport Sciences. A modified version of the “Coach Analysis and Intervention System” (CAIS), developed by Cushion et al. (2012), was used to collect data. A total of 32,886 verbal behaviors were noted and analyzed. Our results suggest that the coaches with university academic backgrounds frequently use more ver…
Reduced complexity models in the identification of dynamical networks: Links with sparsification problems
2009
In many applicative scenarios it is important to derive information about the topology and the internal connections of more dynamical systems interacting together. Examples can be found in fields as diverse as Economics, Neuroscience and Biochemistry. The paper deals with the problem of deriving a descriptive model of a network, collecting the node outputs as time series with no use of a priori insight on the topology. We cast the problem as the optimization of a cost function operating a trade-off between accuracy and complexity in the final model. We address the problem of reducing the complexity by fixing a certain degree of sparsity, and trying to find the solution that “better” satisfi…
Effects of high intensity resistance aquatic training on body composition and walking speed in women with mild knee osteoarthritis : a 4-month RCT wi…
2017
Objective: To investigate the effects of 4-months intensive aquatic resistance training on body composition and walking speed in post-menopausal women with mild knee osteoarthritis (OA), immediately after intervention and after 12-months follow-up. Additionally, influence of leisure time physical activity (LTPA) will be investigated. Design: This randomised clinical trial assigned eighty-seven volunteer postmenopausal women into two study arms. The intervention group (n = 43) participated in 48 supervised intensive aquatic resistance training sessions over 4-months while the control group (n = 44) maintained normal physical activity. Eighty four participants continued into the 12-months' fo…
The possibilities of using the aspen poplar seeds (Populus tremula L.) for the purpose of removing monoaromatic hydrocarbons from an aqueous solution
2018
Sorption of oil-related products (including mainly the propellants) is the very basic process that counteracts spreading these types of pollution into environment. Plenty of synthetic substances are used as sorbents for binding organic compounds (including the monoaromatic hydrocarbons) both from the surface and underground waters. The aim of this paper is to present results of the research on the possibilities of using the aspen poplar (Populus tremula L.) seeds as a sorbent of monoaromatic hydrocarbons from an aqueous solution. In order to increase sorption capacity, the seeds biomass was submitted for the process of mercerizing in diversified time and temperature in water and the NaOH so…
The possibilities of using low-cost fibrous natural materials as sorbents for removing aliphatic hydrocarbons (C6-C15) from an aqueous solution
2020
Sorption of oil-related products (including mainly the propellants) is the basic process that coun-teracts spreading these types of pollution into the environment. Plenty of synthetic substances (including multi-component petroleum products) must be removed both from the fresh and ground-water. The aim of this study was to compare the possibilities of using natural fibrous materials (also weed or waste materials): broadleaf cattail (Typha latifolia L.) seeds, peat and coconut fiber as sorbents of aliphatic hydrocarbons from an aqueous solution. In order to increase sorptive capacity, tested materials were mercerized in hot (80°C) NaOH for sorption properties improvement. The removal of alip…
Comparison of global responses to mild deficiency and excess copper levels in Arabidopsis seedlings
2013
[EN] Copper is an essential micronutrient in higher plants, but it is toxic in excess. The fine adjustments required to fit copper nutritional demands for optimal growth are illustrated by the diverse, severe symptoms resulting from copper deficiency and excess. Here, a differential transcriptomic analysis was done between Arabidopsis thaliana plants suffering from mild copper deficiency and those with a slight copper excess. The effects on the genes encoding cuproproteins or copper homeostasis factors were included in a CuAt database, which was organised to collect additional information and connections to other databases. The categories overrepresented under copper deficiency and copper e…
