The commercialization of the sport from Sports competition Ethics
2012
La ética del deporte surge como una disciplina particular. Podemos encontrar dos lados radicalmente opuestos, el de aquellos que ven la comercialización del deporte como la corrupción del ideal de búsqueda de excelencia inherente a la práctica deportiva, son los partidarios de la «tesis de la corruptibilidad» y la de otro grupo, entre los que se encuentra Simon del «Hamilton College» en EEUU, que sostiene que la comercialización puede presentar un lado positivo éticamente aceptable siempre que se plantee como medio para alcanzar los valores internos en el deporte. En mi exposición abogaré por un enfoque aristotélico que entiende que la prudencia, no sólo comporta el conocimiento de los fine…
Evaluación y clasificación de las revistas científicotécnicas españolas de Ciencias de la Actividad Física y el Deporte
2008
En este artículo se evalúan y clasifican las revistas españolas de Ciencias de la Actividad Física y el Deporte (CCAFD), atendiendo a su calidad global. Para ello se aplica un modelo de evaluación, validado con anterioridad, que combina 23 indicadores relativos a diferentes características de las revistas (formales, de contenido científico y difusión). De esta manera pueden clasificarse las publicaciones periódicas en cuatro categorías de calidad: ‘muy alta’, ‘alta’, ‘media’ y ‘baja’. Los resultados indican que ninguna de las 28 publicaciones existentes alcanza la categoría superior, el 25% obtiene una calidad ‘alta’, el 50% una calidad ‘media’ y otro 25% una calidad ‘baja’. Aunque se obser…
Assessment and classification of Spanish scientific-technical journals of Physical Activity and Sport Sciences
2008
This paper evaluates and classifies Spanish Physical Activity and Sports Science journals according to their overall quality. A previously validated assessment model combining 23 indicators of style, scientific content and diffusion characteristics was used for this purpose. This model classifies journals into four quality categories: ‘very high’, ‘high’, ‘medium’ and ‘low’. None of the 28 journals studied fell into the top category, 25% fell into the ‘high’ category, 50% into the ‘medium’ category, and the remaining 25% into the ‘low’ category. A general improvement was observed compared to previous assessments of these journals, although deficient standardization and a non frequent use of…
Glial Chloride Homeostasis Under Transient Ischemic Stress
2021
High water permeabilities permit rapid adjustments of glial volume upon changes in external and internal osmolarity, and pathologically altered intracellular chloride concentrations ([Cl–]int) and glial cell swelling are often assumed to represent early events in ischemia, infections, or traumatic brain injury. Experimental data for glial [Cl–]int are lacking for most brain regions, under normal as well as under pathological conditions. We measured [Cl–]int in hippocampal and neocortical astrocytes and in hippocampal radial glia-like (RGL) cells in acute murine brain slices using fluorescence lifetime imaging microscopy with the chloride-sensitive dye MQAE at room temperature. We observed s…
Factory Workers' Ordinary User Experiences: An Overlooked Perspective
2018
Experiences with technology often are described as exciting and outstanding, for instance, in relation to novel technologies at home or at work. In this article, we aim to complement this perspective by emphasizing people’s mundane and ordinary experiences with technology, that is, unremarkable experiences happening in the background of people’s attention. Based on our investigations of user experience in a semiconductor factory, we show how such ordinary experiences are substantial in workers’ everyday interactions with technology, which are mainly shaped by repetitive activities and routines. However, current conceptions of user experience seem to overlook those mundane experiences and ho…
Supported liquid membrane extraction of peptides
2001
The application of supported liquid membrane (SLM) extraction for the enrichment of short peptides is presented. The extraction efficiency is dependent on the pH of donor phase and salt concentration in acceptor phase. Moreover, the extraction efficiency is also influenced by the peptide amino-acid sequence and hydrophobicity.

Les habitudes alimentaires des familles françaises pendant le confinement lié au COVID-19 : (comment) ont-elles changé ?
2021
La pandemie liee au COVID-19 a conduit la France a imposer un confinement strict, affectant les habitudes des familles dans de nombreux domaines Cette etude visait a evaluer les changements possibles dans les comportements alimentaires des enfants, les pratiques educatives parentales en matiere d'alimentation et les motivations d'achat des aliments, pendant le confinement par rapport a la periode avant confinement Pendant le confinement, les parents de 498 enfants âges de 3 a 12 ans (238 garcons ;M = 7,32 ;ET = 2,27) ont repondu a une enquete nationale en ligne comprenant les items issus de questionnaires valides (ex CEDQ, CEBQ, HomeSTEAD) Ils ont decrit leur situation et celle de l'enfant …

Reflecting on the PRET A Rapporter Framework Via a Field Study of Adolescents’ Perceptions of Technology and Exercise
2013
PRET A Rapporter (PRETAR) was developed to explicitly structure user-centered evaluation studies to ensure all necessary elements are individually and independently considered. Its creators see its benefit as twofold: for study design and in retrospective evaluations. We evaluate PRETAR’s potential by applying it retrospectively to one of our eHealth field studies in which we investigated the design requirements for mobile technologies that would support and motivate adolescents to exercise opportunistically. We also use PRETAR to evaluate the key literature for this eHealth study. This shows that typically the research methodology is under-reported. Then we document the study in terms of i…
