Competitive intelligence embeddedness: Drivers and performance consequences
2019
Abstract The proliferation of Web-based information sources and social media draw firms' attention to these channels as sources of competitive intelligence (CI). To date, research has focused mainly on information collection techniques rather than on CI uses and its influence on firm performance. We define CI embeddedness as the extent to which management and employees incorporate CI in daily routines, so that actionable knowledge is transferred throughout the organization. A survey of 124 decision makers reveals positive impact of Web CI sources as well as alliances with information providers on CI embeddedness. Furthermore, while CI embeddedness shows no direct influence on firms’ perform…
El fenómeno del sexting entre los adolescentes españoles: prevalencia, actitudes, motivaciones y variables explicativas
2020
Resumen: El sexting es un fenómeno que consiste en el envío y la recepción de fotos, videos y/o mensajes de texto de naturaleza sexual a través de smartphones. Como en todos los demás países desarrollados, se está convirtiendo en una práctica cada vez más popular entre los adolescentes de España. Al tratarse de un fenómeno muy reciente todavía no existen muchos trabajos que hayan estudiado con profundidad su entidad y sus factores implicados. Por tanto, los dos objetivos de este estudio fueron determinar la prevalencia y analizar las variables explicativas del inicio y del mantenimiento de las conductas de sexting. La muestra estuvo formada por 784 adolescentes españoles (52% chicos y 48% c…
First Multi-wavelength Campaign on the Gamma-ray-loud Active Galaxy IC 310
2017
The extragalactic VHE gamma-ray sky is rich in blazars. These are jetted active galactic nuclei viewed at a small angle to the line-of-sight. Only a handful of objects viewed at a larger angle are known so far to emit above 100 GeV. Multi-wavelength studies of such objects up to the highest energies provide new insights into the particle and radiation processes of active galactic nuclei. We report the results from the first multi-wavelength campaign observing the TeV detected nucleus of the active galaxy IC 310, whose jet is observed at a moderate viewing angle of 10 deg - 20 deg. The multi-instrument campaign was conducted between 2012 Nov. and 2013 Jan., and involved observations with MAG…
Wind-luminosity evolution in NLS1 AGN 1H 0707−495
2021
Ultra-fast outflows (UFOs) have been detected in the high-quality X-ray spectra of a number of active galactic nuclei (AGN) with fairly high accretion rates and are thought to significantly contribute to the AGN feedback. After a decade of dedicated study, their launching mechanisms and structure are still not well understood, but variability techniques may provide useful constraints. In this work, therefore, we perform a flux-resolved X-ray spectroscopy on a highly accreting and variable NLS1 AGN, 1H 0707-495, using all archival XMM-Newton observations to study the structure of the UFO. We find that the wind spectral lines weaken at higher luminosities, most likely due to an increasing ion…
Long-term monitoring of mrk 501 for its very high energy γ emission and a flare in 2011 october
2012
"As one of the brightest active blazars in both X-ray and very high energy γ -ray bands, Mrk 501, is very useful for" "physics associated with jets from active galactic nuclei. The ARGO-YBJ experiment has monitored Mrk 501 for γ - rays above 0.3 TeV since 2007 November. The largest flare since 2005 was observed from 2011 October and lasted until about 2012 April. In this paper, a detailed analysis of this event is reported. During the brightest γ -ray flaring episodes from 2011 October 17 to November 22, an excess of the event rate over 6σ is detected by ARGO-YBJ in the direction of Mrk 501, corresponding to an increase of the γ -ray flux above 1 TeV by a factor of 6.6 ± 2.2 from its steady…

Specific transfer effects following variable priority dual-task training in older adults
2016
International audience; Purpose: Past divided attention training studies in older adults have suggested that variable priority training (VPT) tends to show larger improvement than fixed priority training (FPT). However, it remains unclear whether VPT leads to larger transfer effects. Methods: In this study, eighty-three older adults aged between 55 and 65 received five 1-hour sessions of VPT, FPT or of an active placebo. VPT and FPT subjects trained on a complex dual-task condition with variable stimulus timings in order to promote more flexible and self-guided strategies with regard to attentional priority devoted to the concurrent tasks. Real-time individualized feedback was provided to e…
Juan Alberto Kurz Muñoz y su aportación a la historiografía del arte ruso
2010
Artículo bio-bibliográfico en el que se presentan las principales aportaciones del historiador del arte Juan Alberto Kurz Muñoz en el ámbito de los estudios artísticos, en especial del arte ruso-soviético, así como su labor docente y de gestión en el Departament d'História de l'Art de la Universitat de Valencia. Una síntesis de su trayectoria académica en la que se aprecia claramente su preocupación personal por impulsar los estudios relacionados con el arte ruso, particularmente en el seno de la institución universitaria. Un objetivo claramente logrado y del que fue pionero a comienzos de la década de los setenta. (A)
La Sociedad Valenciana de Bellas Artes o el Centro artístico de la Calle de Cabilleros (1889-1891): el antecedente más inmediato del Círculo de Bella…
1999
La carencia de un centro en el que reunirse, trabajar, exhibir y comercializar sus producciones impulsó a los artistas valencianos a crear en 1889 la Sociedad Valenciana de Bellas Artes. No obstante su breve vida -hasta 1891-, la importancia de este centro artístico reside en haber sido el germen del Círculo de Bellas Artes de Valencia, una de las sociedades culturales más activas desde finales del ochocientos.
