La externalización como estrategia de creación del tercer canal. El caso de la Televisión Autonómica de Murcia
Within the area of public regional television management in Spain, the phenomenon of outsourcing was embraced by both the public and private sectors in the 80s. The aim of this article is, on the one hand, to clarify the concept of outsourcing in its application to the public sector and determine its legal limits in public regional audiovisual companies and, on the other, to analyse Murcia Autonomous Television as a unique Spanish case in which outsourcing has been carried out at various levels. As there is very little scientific research on this subject, the research techniques in this article are based on the analysis of documentation that outlines the outsourcing procedures in addition to consultations with the agents involved from the different public radio and television broadcasting firms

Nuevas aportaciones al coleccionismo español de la Edad Moderna: La galerÃa de retratos de la familia Velasco
En el transcurso de los trabajos de catalogación del archivo familiar Sánchez Tagle salió a la luz un documento (sin fecha) que contenÃa una relación de 41 retratos situados en una estancia de la Casa del Cordón (Burgos). Se trata de una descripción de la galerÃa de retratos de la familia Velasco, Condestables de Castilla, encargada por don Juan Fernández de Velasco, VI Condestable. En ella se encontraban retratados algunos de los miembros más ilustres del linaje entre los siglos XIII al XVII, cuyos nombres, tÃtulos nobiliarios, atuendo s y peinados se describen en este documento anónimo. En 1608 la galerÃa se encontraba en la biblioteca de la Quinta de Mirafuentes, residencia madrileña del VI Condestable, donde permaneció hasta su fallecimiento en 1613. Después fueron trasladados a la Casa del Cordón, manteniéndose allà hasta principios del siglo XIX. Actualmente se encuentran en paradero desconocido.In the process of cataloguing the Sanchez Tagle familiar archive an undated document carne to light which contained an account of 41 portraits situated in a room of the Casa del Cordón (Burgos). It concems a description of the portrait gallery of the Velasco family, Constables of Castile, commissioned by Juan Fernández de Velasco, the sixth Constable. In it, some of the most illustrious members of the lineage from the 13th to 17th century were portrayed, whose names, noble titles, attires and hairstyles are described in this anonymous document. In 1608 the gallery was situated in the library of the Quinta de Mirafuentes, the residence in Madrid of the sixth Constable, where it remained until his death in 1613. Later they were removed to the Casa del Cordón, where they were kept until the beginning of the 19th century. Their whereabout are unknown

Both documents provide new information on the close link between this Baroque building and religious architecture of Valladolid
El papel social y educativo de la biblioteca pública: Treinta años de la Red de Bibliotecas Municipales de Salamanca
Trabajo Fin de Grado en Información y Documentación, curso 2014-2015[ES] El papel social y educativo de las bibliotecas públicas se ha fortalecido en los últimos tiempos debido a una serie de factores económicos, polÃticos, sociales y tecnológicos, que han supuesto una grave crisis de valores en la sociedad. Sin embargo este papel no es nuevo y desde hace muchos años, las bibliotecas públicas de todo el mundo, han elaborado programas y diseñado sus espacios y actividades en función de las necesidades sociales y educativas de la comunidad en la que se insertan. La Red de Bibliotecas Municipales de Salamanca ha sido un referente en esta labor social y, desde hace más de treinta años, ha tenido entre sus principales objetivos convertirse en un espacio de información, educación, ocio y participación ciudadana. Este trabajo recoge la historia de esta Red de Bibliotecas haciendo especial hincapié en ese papel social y educativo que lleva realizando a lo largo de más de tres décadas.
[EN] The social and educational role of public libraries has been reinforced in the last few years due to a number of economical, political, social and technological factors, which meant a serious crisis of values in society. However, this role is not new and, for a long time, public libraries all around the world have elaborated programmes and designed their areas and activities according to the social and educational needs of the community in which they are instituted. The Network of Municipal Libraries of Salamanca has been a reference in this social work and, for over thirty years, one of its main goals has been to become a space for information, education, leisure and community involvement. This work gathers the history of this Network of Libraries, laying emphasis on the social and educational role that has been performing for more than three decades
Actions of the entreprise’s social responsibility.Does it attract, retain and motivate theintellectual capital of the company?
[Resumo] Este artigo establece, a través dunha investigación de campo, a importancia da implantación da responsabilidade social nas empresas co fin de estas reteren o seu capital intelectual. A fugade cerebros e a retención do talento é arestora un tema de actualidade que preocupa as grandes entidades, as cales intentan motivar, atraer e reter o seu know how para lograren desta forma posicionarse como lÃderes no seu sector ou nicho de mercado. Para isto, implementan dentro das súas polÃticas a responsabilidade social empresarial, con accións que varÃan en función da xeración a que pertence o seu cadro de persoal e que se relacionan neste estudo.[Abstract] This article establishes the importance of the implantation of the enterprise social responsibility in the companies to retain its intellectual capital through a field research. The brain drain and the retention of talent, are very current subjects and a concern for the big companies, that try to motivate, to attract and to retain its know how and thus to position themselves as the leader sin its sector or niche of market. For this reason, they implement enterprise social responsibility within their policies, with actions that vary based on the generation to which their group belongs and that is related in this study
The strength of handcraftin defence of its legitimacy and identity
[Resumo] O movemento social é de gran transcendencia histórica ao longo dos tempos. Plasmaremos nesta investigación a importancia que adquire o traballo artesán a través do movemento social reivindicativo por medio dun instrumento folclórico. O pobo artesán persegue con este movemento social a lexitimidade e a súa propia autodefinición. O compromiso histórico reconstrúese mediante a definición do traballo, en especial do traballo colectivo artesán. A definicióndo traballo plásmase como impulso do compromiso colectivo, que chega a mobilizar a cidade a través de actos folclóricos que reivindican o traballo artesanal e alcanzan a dignificar evalidar os sistemas creativos da autodefinición da nación. Arestora ponse en dúbida o rol social que ocupan os actores do folclore e as organizacións nocontorno do traballo, o seu compromiso colectivo dentro da sociedade, mais a mobilización de toda unha cidade consegue reivindicar que o traballo artesanal dignifica e valida os sistemas creativos de autodefinición da nación. Os sistemas organizativos mutuais, conceptos derecoñecemento e solidariedade, son necesidades que se plasman como resposta ao coñecemento dunha nación.[Abstract] Social movement has had a great historical significance over time. In this research, the importance of handcraft is reflected through the demanding social movement using a folk instrument. With this social movement the artisan community pursues legitimacy and selfdefinition. Historic commitment is reconstructed through the definition of work, in particular,handcrafted work. The definition of work is reflected as the force of the collective commitment,mobilizing the city through traditional actions that defend craftsmanship, dignifying and validating the creative systems of the nation’s self-definition. Although the social role that the actors and organizations play is put in doubt, once the collective commitment is established,the mobilization of an entire city manages to show that handcrafted work dignifies and validates the nation’s creative systems of self-definition. Mutual organizational systems, concepts ofrecognition and solidarity, are requirements which are reflected as a response to the recognitionof a nation
Unexpected formation of a silicon-centered spirocyclic oligosiloxane bearing eight pendant ferrocene units
An intriguing but rare silicon-centered spirocyclic compound, spiro[5.5]octaferrocenylpentasiloxane (4) featuring silicon fused six-membered ferrocenyl-functionalized siloxane rings, has been obtained during the thermally induced transformation of triferrocenylsilane Fc3Si–H (1) into triferrocenylsilanol Fc3Si–OH (2), when N,N-dimethylformamide (DMF) was used as a solvent in the presence of the metal carbonyl Mo(CO)6. The unexpected formation of the maximally ferrocenyl substituted silicon centered spirocyclic 4 involves the obtention, and subsequent condensation, of different ferrocenylsilanol intermediates. Spirocyclic silicate 4 has been characterized using a combination of MALDI-TOF mass spectrometry, elemental analysis, and single crystal X-ray diffraction analysi
A convergent growth approach to electroactive ferrocene rich carbosilane- and siloxane-based dendrons, dendrimers, and dendronized polymers
The construction of the first members of a novel family of structurally well-defined, ferrocenyl rich, dendritic macromolecules based on carbosilane skeletons and siloxane linkages has been achieved via a convergent growth approach. Starting from triferrocenylvinylsilane Fc3SiCHvCH2 (1) (Fc = Fe(η5
-C5H4)(η5

C5H5) as the key monomer, the sequential utilization of platinum-catalyzed hydrosilylation and alkenylation steps with Grignard reagents (allylmagnesium bromide) can be applied to prepare three different
branched structures: multiferrocenyl-terminated dendrons 2 and 3, dendrimers 4 and 5, and dendronized
polymers 7n–9n. All of the dendritic metallomacromolecules have been thoroughly characterized using a
combination of elemental analysis, multinuclear (1
H, 13C, 29Si) NMR spectroscopy, FT-IR and MALDI-TOF
mass spectrometry, to establish their chemical structures and properties. The molecular structures of G1-
dendron 3 and dendrimer 4, containing six and nine ferrocenyl units, respectively, have been successfully
determined by single-crystal X-ray analysis, compound 4 being the branched multiferrocenyl-containing
siloxane with the highest number of Fc substituents whose structure has been reported so far.
Electrochemical studies (using cyclic voltammetry (CV) and square wave voltammetry (SWV) performed in dichloromethane solution with [PF6]
− and [B(C6F5)]4− as supporting electrolyte anions of different coordinating
abilities) reveal that all the macromolecular compounds obtained exhibit a three-wave redox pattern,
suggesting appreciable electronic interactions between the silicon-bridged triferrocenyl moieties as they are
successively oxidized. In addition, dendrimer 5 and dendronized polymers 7n–9n, with 12 and 4 < n < 14 ferrocenyl units, respectively, linked in threes around the periphery, undergo remarkable oxidative precipitation
in CH2Cl2/[n-Bu4N][PF6] and are able to form chemically modified electrodes with stable electroactive filmsWe thank the Ministerio de Ciencia e Innovación (MICINN) of
