La piratería de cine y series en el AMG. ¿Una distribución alternativa?

Esta investigación aborda la piratería de productos audiovisuales (películas y series) en el AMG, cómo ha ido evolucionando la distribución y su adaptación a través de los años, tanto en formatos físicos como digitales, así como los problemas que ésta presenta y las diferentes perspectivas del consumidor y de expertos del medio audiovisual. La piratería es un negocio ilegal, pero también puede significar un recurso valioso para las audiencias que la consumen, ayuda a la preservación de filmes que se consideraban perdidas y gracias a ello son vistas por más personas, ya que los altos costos del streaming y las salas de cine orillan a buscar alternativas que no afecten su economía o bien, no implica gasto alguno.ITESO, A.C

Anomaly in the dielectric response at the charge orbital ordering transition of crystalline Pr0.67Ca0.33MnO3

The complex impedance of a Pr0.67Ca0.33MnO3 crystal has been measured. The frequency dependence is studied for a wide range of temperatures (50K-403K) and is found to be characteristic of relaxation process with a single Debye time relaxation constant, which is interpreted as a dielectric constant of the material. A strong peak is observed in this dielectric constant (up to two millions) at the charge ordering transition suggesting an interpretation in terms of ordering of electric dipoles at TCO or in term of phase separation. Comparison with Pr0.63Ca0.37MnO3 - in which the phase separation is much smaller and the peak in the dielectric constant is absent - suggests an interpretation in term of phase separation between insulating and metallic states.Comment: pdf fil

DETERMINATION OF DISTINCTIVE COMPETENCIES IN SMES: THE CASE OF VIGO AND ITS AREA OF INFLUENCE (SPAIN)

SUMMARY The sources of competitive advantages are characteristic of the enterprises that allow them to be placed in better position than their competitors. As from the theory of resources and capacities it is habitual to consider that those sources are in internal and external factors of the enterprises. The entrepreneur, by means of the strategy combines these factors establishing his distinctive competencies. This paper analyzes the formation of distinguishing competences. The obtained results show the form in which the small and medium enterprises (SME) organize their resources and capacities to form distinctive competencies. The SMEs of Vigo study their area of influence, a region of northwest Spain. In that case it is obtained that they form 5 great distinguishing competencies: management of human and technological resources, management of territorial resources, management of clients, management of products and innovation. These agree to a large extent with previous papers, although their contents present some differences. "Visión de Futuro" Año 7, Nº2 Volumen Nº14, Julio -Diciembre 2010 URL de l

DETERMINACIÓN DE COMPETENCIAS DISTINTIVAS EN PYMES: EL CASO DE VIGO Y SU ÁREA DE INFLUENCIA (ESPAÑA)

Las fuentes de ventajas competitivas son características de las empresas que les permiten situarse en mejor posición que sus competidores. Partiendo de la teoría de recursos ycapacidades es habitual considerar que esas fuentes se encuentran en factores internos y externos de las empresas. El empresario, mediante la estrategia combina dichos factores estableciendo sus competencias distintivas. Este trabajo analiza la formación de competenciasdistintivas. Los resultados obtenidos muestran la forma en que las pequeñas y medianas empresas (PYME) organizan sus recursos y capacidades para formar competencias distintivas.Se estudian las Pymes de Vigo y su área de influencia, una región del noroeste de España. En ese caso se obtiene que forman 5 grandes competencias distintivas: gestión de recursos humanos y tecnológicos, gestión de los recursos territoriales, gestión de clientes, gestión de losproductos e innovación. Estos coinciden en gran parte con trabajos previos, si bien sus contenidos presentan algunas diferencias

Observation of two transient episodes in an Arctic Coastal Polynya in late winter: Supercooled water and sea ice desalination

International audienceCoastal Arctic polynyas play an important role in forming dense water and contribute to the deep ocean ventilation. Dense water formation results from brine rejection associated with sea-ice production. In March 2007, a 60m-long ice tethered mooring, recording temperature and salinity at high frequency with a relatively fine vertical resolution and a prototype float (Ice-T) measuring ice-thickness and thermal profiles in sea ice were deployed in Storfjorden in the Svalbard archipelago. This fjord hosts a latent heat polynya which is maintained open under northeasterly wind conditions. The water masses analysis reveals that the main pool of the fjord is occupied by Brine-enriched Shelf Water (BSW) over the whole water column, while the southwest part of the fjord is occupied by Arctic Water (ArW). The BSW recorded at the bottom of the mooring has a salinity of 35.2 (density of 28.31 kg m-3), which is among the densest values of BSW reported in this region in the literature. Measurements indicate that the water column is slightly supercooled down to 30m for the first day of the record until a warm storm breaks the ice. Maximum supercooling values are 0.007±0.002°C below the in-situ freezing point with a mean value of 0.005±0.002°C at 10m. The origin of this supercooled water is investigated by analyzing the ice cover and the ocean-atmosphere heat flux during the days that preceded these observations. Although the amount of supercooling is relatively low compared with values recently reported in Storfjorden, these observations show that supercooled water can still be present under the ice several days after the cooling and freezing period. A sudden and brief salinity anomaly reaching 0.2 ppt is observed at the base of the ice. Concomitant temperature anomalies are recorded in the sea ice. The origin of this signal, which occurs during a warm storm, is analyzed. As this salinity anomaly cannot be associated with ice formation, different sea ice desalination processes are investigated, in particular flushing by meltwater and gravity drainage
