Conceptualización de los medios sociales: oportunidades para la gestión del deporte
2019
Resumen Los medios sociales son un fenómeno que está cambiando la forma en la que las personas nos comunicamos y relacionamos, con muchos millones de usuarios en todo el mundo. En el contexto de la gestión del deporte, los medios sociales están desempeñando actualmente un papel cada vez más relevante en el día a día de clubes, atletas, federaciones, empresas, investigadores, etc. Sin embargo, los estudios realizados hasta el momento sobre medios sociales indican que hay una falta de consenso teórico respecto al término, confundiéndolo en muchas ocasiones con el significado de otros conceptos vinculados a los mismos, algo que puede estar limitando el desarrollo de todo el potencial que tiene…

Ethernet FSO Communications Link Performance Study Under a Controlled Fog Environment
2012
In this letter the performance of a free space optical (FSO) communication link in the presence of fog is experimentally investigated in an indoor environment. A dedicated indoor atmospheric chamber, replicating the outdoor environment, is being used to evaluate the FSO link performance under the fog condition. Theoretical analysis supported by the experimental evaluation has been carried out for the intensity modulation/direct detection on-off keying non-return-to-zero (OOK-NRZ), OOK return-to-zero (OOK-RZ) and four pulse position modulation (4-PPM) modulation formats at the Ethernet baseline data-rate. The results shown indicate that the 4-PPM signalling scheme is the most robust to the f…
Etica e politica nel giovane Marx
2015
Se si vuole avere una visione d’insieme della vasta ed articolata produzione di Karl Marx, non si può trascurare la serie degli articoli scritti in varie riviste nel breve ma intenso segmento cronologico intercorso tra il 1842 ed il 1843. Il periodo di riferimento è quello che, dall’anno successivo al conseguimento della laurea in filosofia presso l’Università di Jena, conduce il giovanissimo Marx al trasferimento nella città di Parigi.
Review of the quality of youTube videos recommending exercises for the COVID-19 Lockdown
2022
Background: The world is experiencing a pandemic caused by COVID-19. Insufficient physical activity can increase the risk of illness. Trying to replicate a normal search that any user/patient could do in YouTube, the objective of this study was to evaluate the quality of YouTube videos related to home exercises during lockdown and their adherence to World Health Organization (WHO) recommendations. Methods: A simple search was carried out on YouTube. The first 150 videos were selected. After applying exclusion criteria, 68 videos were analyzed and evaluated. Two statistical analyses based on machine learning techniques were carried out. Videos were classified according to principal component…
Generation of Design Principles as Knowledge Conversion - Elucidating Dynamics
2021
In this paper we apply the perspective of knowledge conversion with recent identified core elements for developing design principles to elucidate the dynamics of design principles. In the paper, the elements of influence, actors, and formulation are integrated in a knowledge conversion process of socialization, externalization, combination, and internalization – through which tacit knowledge is made explicit, shared, and turned into action. We exemplify this process with three empirical cases using action design research (ADR) to develop IT artifacts and generate design principles. Our paper shows the dynamics across a process of generating design principles. Viewing the generation of desig…

Jean-Paul Sartre tra fenomenologia e psicologia
2017
Phenomenology and psychology are two fundamental disciplines of culture in the 20th century. The phenomenology of Husserl was assimilated by Sartre at the beginning of the century, until the publication of L’être et le néant (1943). In fact, studies of Sartre’s works demonstrate that his philosophy of existence is closely linked to transcendental phenomenology and psychology. Furthermore, the key words of “being” and “nothing” allow one to follow the evolution of Sartre’s thinking from the philosophy of existence to Marxism. In this sense, the historical materialism exhibited in the Critique de la raison dialectique (1960) can be understood as social psychology in the context of human histo…
Presentación del Monográfico: una mirada a la emigración española cualificada reciente: Estado de la cuestión y enfoques teóricos
2018
The study of qualified emigration has returned to the political and scientific agendas in recent decades. Currently the theoretical approaches have changed from a completely renewed economic, political, social and technological context. This article presents a summary of these new approaches and a current overview of skilled migration of Spaniards, based on a review of the specialized literature.
