    El proceso innovador enfrenta una serie de fallos de mercado y por esta razón – y por ser considerado uno de los principales agentes del crecimiento económico en el mundo – un significativo número de políticas gubernamentales y supra-nacionales son diseñadas para promover el progreso tecnológico. En Europa la situación no podría ser diferente y la “Paradoja Europea” es utilizada como principal argumento para la implementación de iniciativas relacionadas a la innovación. Junto con estas políticas hay una creciente preocupación con su continua evaluación, teniendo como objetivo proveer feedbacks para la adaptación y adecuación de estos programas con las necesidades de los agentes involucrados. En este sentido, el presente paper desarrolla una evaluación de los impactos del Programa Eureka para el caso de las empresas españolas participantes en esta iniciativa y con proyectos concluidos entre los años 2000-2005 (a través de análisis de los informes finales de los proyectos). Un total de 77 empresas fueron abordadas con métodos cuantitativos (correlaciones, testes chi-cuadrado, análisis discriminante y análisis de cluster). Los resultados demuestran que la participación española en Eureka suele tener altos niveles de logros tecnológicos. Los logros comerciales parecen estar definidos por la calidad del funcionamiento del proyecto y por la capacidad de las empresas en explotar sus resultados en el mercado ya antes del fin del proyecto. Una tipología introductoria de los participantes es propuesta en 3 conglomerados: (1) Risky Innovators; (2) Inventors; y (3) Consistent Innovators.Innovation is a process that faces several “market failure” situations and for this reason – and for being considered one of the main drivers of economic growth throughout the world – a large number of governmental and supranational policies are designed to foster technological progress. In Europe this situation could not be any different and the “European Paradox” is used as the main argument for the implementation of innovation related initiatives. Along with these policies, there is an increasing concern with their continuous evaluation aiming at providing valuable feedback for these program’s adaptation and adequacy to the player’s needs. In this sense, this paper develops an evaluation of Eureka Programme’s impact for the case of Spanish companies participating in this initiative and that had projects finished in the period 2000-2005 (analysis performed through the information contained in Eureka’s Final Reports). A total of 77 firms were assessed through quantitative methods, namely correlations, chi-square tests, discriminant models and cluster analysis. Findings show that Spain participates in Eureka mainly through SMEs, and that the overall rate of technological achievements is impressively good. Commercial achievements seem to be influenced mainly by the quality of the project’s functioning and the capacity of firm’s exploiting results in the industry by the end of the project. A basic typology of participants is offered in which three clusters are built: (1) Risky Innovators; (2) Inventors; and (3) Consistent Innovators.Innovation Policy; Eureka Programme; Spanish Innovation System; R&D Collaboration, Políticas de Innovación; Programa Eureka; Sistema de Innovación Español; Colaboración en I+D.

    Towards a Taxonomy of Firms Engaged in International R&D Networks: an Evaluation of the Spanish Participation in Eureka

    Innovation is increasingly becoming an internationalized process and a strategy that has recently been playing a central role in this scenario is that of R&D collaboration. To assess the outcomes of this strategy we develop an evaluation of Eureka Programme’s impact for the case of Spanish companies participating in this initiative and that had projects finished in the period 2000-2005. A total of 77 firms were assessed through statistical association methods and cluster analysis. Company size, Role in the Project, Firm Sector and R&D intensity are significantly associated with the projects’ impacts on Spanish participants. A consistent taxonomy is offered in which three clusters are built: (1) Risky Innovators; (2) Inventors; and (3) Consistent Innovators

    Technological Attraction of FDI flows in Knowledge-Intensive Services: a Regional Innovation System Perspective for Spain

    Get PDF
    An increasing body of literature has been generated regarding the role that services play in innovation systems, in which special attention has been paid recently to Knowledge-Intensive (Business) Services – KIS & KIBS. As not only developed nations but also emerging economies and regions embedded in this country-level unit of analysis show an economic structure strongly based in the tertiary sector, it is mandatory for policymaking processes to better evaluate and understand the idiosyncrasies of these innovation-generating services and its relationships with National, Sectoral and Regional Innovation Systems. Thus, this article aims at approaching the dynamics of Foreign Direct Investment (Inward and Outward flows) in KIS in Spain considering the Regional (NUTS 2) level of analysis and taking into account their interactions with the innovative environment of two specific regions (Madrid and Andalusia) by testing a regressive model built upon technological and innovation systems’ variables. The novelty of our approach is to propose a model based on innovation-driven determinants of FDI attraction where: a) the size of innovation systems is approximated by GERD (controlled by GDP) and by a Human Resources variable (Researchers in R&D); and b) technological heterogeneity is measured according to the technological gap between region/country (using a Patent Index proxy). This approach, although novel to our understanding is based on a broad set of references on FDI (Investment Development Path, Asset Augmenting Strategies), internationalization and Innovation Systems (Knowledge Generation, Absorptive Capacity). Preliminary results do not indicate that Innovation Systems affect relevantly the FDI flows for the analyzed regions/countries, suggesting that FDI behaves generally according to a market seeking logic, rather than asset seeking. Improvements for econometric estimations are suggested

    Twisted exchange interaction between localized spins embedded in a one- or two-dimensional electron gas with Rashba spin-orbit coupling

    We study theoretically the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction in one- and two-dimensions in presence of a Rashba spin-orbit (SO) coupling. We show that rotation of the spin of conduction electrons due to SO coupling causes a twisted RKKY interaction between localized spins which consists of three different terms: Heisenberg, Dzyaloshinsky-Moriya, and Ising interactions. We also show that the effective spin Hamiltonian reduces to the usual RKKY interaction Hamiltonian in the twisted spin space where the spin quantization axis of one localized spin is rotated.Comment: 4pages, no figur

    Gauging the effect of supermassive black holes feedback on quasar host galaxies

    In order to gauge the role that active galactic nuclei play in the evolution of galaxies via the effect of kinetic feedback in nearby QSO 2’s (z ∼ 0.3), we observed eight such objects with bolometric luminosities Lbol∼1046ergs−1 using Gemini Multi-Object Spectrograph-integral field units. The emission lines were fitted with at least two Gaussian curves, the broadest of which we attributed to gas kinetically disturbed by an outflow. We found that the maximum extent of the outflow ranges from ∼1 to 8 kpc, being ∼0.5±0.3 times the extent of the [OIII] ionized gas region. Our ‘default’ assumptions for the gas density (obtained from the [SII] doublet) and outflow velocities resulted in peak mass outflow rates of M˙defout∼ 3–30 M⊙yr−1 and outflow power of E˙defout∼1041–1043ergs−1⁠. The corresponding kinetic coupling efficiencies are εdeff=E˙defout/Lbol∼7×10−4–0.5 per cent, with the average efficiency being only 0.06 per cent (0.01 per cent median), implying little feedback powers from ionized gas outflows in the host galaxies. We investigated the effects of varying assumptions and calculations on M˙out and E˙out regarding the ionized gas densities, velocities, masses, and inclinations of the outflow relative to the plane of the sky, resulting in average uncertainties of 1 dex. In particular, we found that better indicators of the [OIII] emitting gas density than the default [SII] line ratio, such as the [ArIV] λλ4711,40 line ratio, result in almost an order of magnitude decrease in the εf

    Requirements for the LHC collimation system

    The LHC requires efficient collimation during all phases of the beam cycle. Collimation plays important roles in prevention of magnet quenches from regular beam diffusion, detection of abnormal beam loss and subsequent beam abort, radiation protection, and passive protection of the superconducting magnets in case of failures. The different roles of collimation and the high beam power in the LHC impose many challenges for the design of the collimation system. In particular, the collimators must be able to withstand the expected particle losses. The requirements for the LHC collimation system are presented

    Bipolar ionization cones in the extended narrow-line region of nearby QSO2s

    We have used narrowband [O III] λλ4959, 5007 and Hα+[N II] λλ6548, 84 Hubble Space Telescope (HST) images of nine luminous (L[O III]>1042 erg s−1) type 2 QSOs with redshifts 0.1<z<0.5 in order to constrain the geometry of their extended narrow-line regions (ENLRs), as recent ground-based studies suggest that these regions become more spherical at high luminosities due to destruction of the torus. We instead find elongated ENLRs reaching 4–19 kpc from the nucleus and bipolar ionization cones in [O III]/(Hα+[N II]) excitation maps indicating that the torus survives these luminosities, allowing the escape of ≈10 times higher ionizing photon rates along the ionization axis than perpendicular to it. The exceptional HST angular resolution was key to our success in arriving at these conclusions. Combining our measurements with previous ones based on similar HST data, we have revisited the relation between the ENLR radius Rmaj and L[O III] over the range 39<log(L[O III])<43.5 (L in erg s−1): log(Rmaj)=(0.51±0.03) log(L[O III]) −18.12±0.98. The radius of the ENLR keeps increasing with L[O III] in our data, implying that the ENLR can extend to distances beyond the limit of the galaxy if gas is present there—e.g., from active galactic nucleus (AGN) outflows or interactions, seen in six objects of our sample. We attribute the flattening previously seen in this relation to the fact that the ENLR is matter-bounded, meaning that ionizing photons usually escape to the intergalactic medium in luminous AGNs. Estimated ionized gas masses of the ENLRs range from 0.3 to 2×108Me, and estimated powers for associated outflows range from <0.1% to a few percent of the QSO luminosity
