LA ESTRATEGIA DE OUTSOURCING INTERNACIONAL EN ESPAÑA: UNA APROXIMACIÓN A LOS SECTORES MANUFACTUREROS TRADICIONALES / THE STRATEGY OF INTERNATIONAL OU…
2009
En los últimos años el uso por parte de las empresas de la estrategia de outsourcing en sus dos vertientes (nacional e internacional)1 está siendo una práctica habitual en los países desarrollados, especialmente en los sectores manufactureros tradicionales. Dado el desarrollo experimentado y las implicaciones técnico-productivas y sociales que se derivan de su implementación, en este trabajo analizamos cuál ha sido la tendencia de esa estrategia en estos sectores durante el periodo 1985-2004 y contrastamos qué relación existe entre ésta y dos de sus principales factores determinantes: el tamaño y la experiencia internacional. De los resultados más generales se desprende que el outsourcing m…
Ethylene and phenylene bridged polysilsesquioxanes functionalized by amine and thiol groups as adsorbents of volatile organic compounds
2007
Abstract Ethylene and phenylene bridged polysilsesquioxane xerogels having amine and thiol groups attached to the surface have been obtained by the sol–gel method from 1,2-bis(triethoxysilyl)ethane or 1,4-bis(triethoxysilyl)benzene and functionalized silanes in the presence of an ammonium fluoride catalyst in an ethanol solution. The synthesized samples have a porous structure (700–850 m2/g) and a high content of functional groups (1.4–1.9 mmol/g). The obtained porous bridged polysilsesquioxanes exhibit a considerable affinity for adsorbing several organic compounds (n-hexane, n-heptane, benzene, cyclohexane, acetonitrile and triethylamine) from the gas phase. The sample with an ethylene br…
Phytoplankton assemblages in reservoirs: Is it chemical or physical constraints which regulate their structure?
1998
Data on phytoplankton assemblages and the correspondent environmental variables, collected in a limnological investigation carried out on 21 Sicilian reservoirs between 1987 and 1988, were ordered to clarify which physical (light availability, mixing depth), chemical (nutrient availability) and biological (grazing pressure) parameters modulate the structure of the assemblages. In particular, data sets were analyzed using CANOCO 3.1. The results of the analysis have shown that physical factors are more important in selecting species for those environments subject to pronounced water-level fluctuations. The reasons of such strong influence may be understood in the secondary modifications that…
Des traces et des hommes : projet interdisciplinaire pour interpréter les comportements techno-économiques des Néandertaliens
2009
Cette contribution expose les problematiques du PCR « Des Traces et des Hommes », un projet de recherche interdisciplinaire sur les modalites d’acquisition et de traitement des matieres vegetales et animales au Paleolithique moyen en Europe occidentale. Elle presente brievement les differentes experimentations effectuees entre 2007 et 2009 et les resultats preliminaires obtenus dans chacun des themes developpes.
Deux espèces sous un même masque. Le point de vue paléontologique piégé par les coquilles de deux espèces européennes de Trivia (Mollusca, Gastropoda…
2006
16 pages; Lʼexpérience tentée dans ce travail a pour but dʼévaluer certaines conséquences des lacunes dʼinformation liées à la fossilisation sur la perception de lʼespèce en paléontologie. Cette expérience consiste à mener une étude de « type paléontologique » sur du matériel actuel puis à relire les résultats à la lumière des connaissances biologiques. Lʼobjet et le cadre de lʼétude ont donc été sélectionnés pour disposer dʼun matériel abondant et de bonne qualité dans un contexte spatio-temporel bien défini, et ainsi permettre de simuler ou non des lacunes dʼinformation. Trivia arctica et T. monacha, deux espèces proches de gastéropodes marins actuels vivant dans les eaux infra-littorales…
The Future of National News Agencies in Europe. Case study 2 : The survival challenges for news agencies in a small market : News agencies in the Bal…
2019
This case study provides complementary explanatory information for understanding the current state and future prospects of European national news agencies. It focuses on the Baltic news agencies, BNS (Estonian and Lithuanian branches), LETA (Latvia) and ELTA (Lithuania), as examples of news services in small markets. Our purpose was to investigate how news agencies in small markets respond to the challenges of the internet, digitalisation and the social media era, which has altered their formerly indispensable position in the news ecosystem. All the news agencies in the Baltic countries declare as their primary role the serving of society with reliable and diverse information. In order to s…
Formation et compétitivité des régions européennes
1991
Parc technologique, industrie pilote,... dans la logique de l'aménagement du territoire, l'accent semble de plus en plus mis sur la dotation en ressources humaines d'une zone géographique. Comme, d'autre part, la capacité à exporter conditionne l'essentiel des possibilités de croissance économique, on peut s'interroger sur l'impact d'une forte dotation en capital humain comme avantage absolu des produits sur les marchés extérieurs. Dans une recherche par l'entreprise de source de compétitivité, la localisation dans une région à haut niveau de formation de la main d'oeuvre peut être une stratégie a priori pertinente. Dans ce texte, on tente de donner une explication des performances d'une ré…
La morphologie des tissus urbains et périurbains à travers une lecture fractale
2005
Urban expansion produces an irregular urban fabric. This phenomenon influences areas which are distant from urban centres, a problem for sustainable development. Solutions proposed to reduce urban expansion are modelled on the pattern of the compact town. Generally, it is believed that these solutions are unacceptable to the people concerned. In this article we present an alternative approach to the study of urban fabric, which shows that, despite their irregular form, it is possible to describe their development using fractal analysis. This permits understanding of the socio-economic causes of this process and the development an alternative conceptual approach to the management of urban ex…
Introducing the Study of Nordic Cooperation
2020
To rediscover Nordic cooperation this article develops a ‘conceptual grammar’ that provides general theoretical ‘images’ of cooperation that are systematically applied. Being supplementary analytical constructs, moreover, these images capture great variety and differentiation in Nordic cooperation. Next, this article provides a review of two sets of literature that are of particular relevance to this thematic issue. The first is a broader literature on European integration. The second is studies of Nordic cooperation. The article closes with an overview of the contributions to this thematic issue.
European Union directives and clinical practice in nursing education in the Nordic countries
2019
Nursing education in countries belonging to the European Union (EU) must follow EU directive requirements. The aim of this opinion paper is to explore and discuss the challenges presented by EU requirements to clinical practice in nursing education. These requirements prescribe that clinical practice must be carried out in a variety of different and specialized areas that provide care in hospital units. This may offer students only a limited range of experience; thus, they may not be fully prepared to care for patients with common diseases, and only have a restricted knowledge about the ongoing development of caring for patients at home. EU directives require that half of a nursing educati…
