Assessing technology-based spin-offs from university support units

This paper takes a regional studies approach to assess spin-offs from a university-based technology transfer network. We first detect the regional objectives, inputs and outputs needed to assess spin-offs from support programmes. We then provide evidence on regional mechanisms for firm creation. We analyse spin-offs created at Catalan universities and find that many efficient spin-offs have formal technology transfer agreements, and emerge from technology-oriented universities. We also find that higher innovation levels and experience from the parent university are associated with higher efficiency, which is positively related to future fundamental profitability. Finally, we propose regional policy making and research directions.

El mercat del vi espanyol als Estats Units

L’objecte d’estudi d’aquest projecte final, és el mercat del vi espanyol als Estats Units. Es tracta d’un mercat relativament jove degut a que la cultura del vi per un nord-americà amb una renda mitja es nova. Encara així, els Estats Units es el tercer país amb major consum per volum del món. Per tal de poder entendre millor aquest mercat, s’estudiaran les diferents característiques del país, les regions on es produeix el vi i la seva distribució i els diferents agents que s’impliquen en aquest procés en el país. Un cop analitzat els aspectes econòmics i les característiques més importants d’Estats Units, es realitzarà una anàlisi de l’oferta i de la demanda del sector del vi en aquest país per poder realitzar una comparativa més endavant amb el mercat del vi espanyol i de la perspectiva que es té a Estats Units sobre aquest tipus de vi. Un aspecte molt important que s’ha observat es la dificultat d’accés al mercat del vi a Estats Units. Per això, s’ha dedicat un capítol sencer a analitzar els diferents controls i regulacions que s’han de tenir en compte alhora d’importar vi a aquest país americà. Per últim, es realitza un anàlisi del mercat del vi espanyol i la perspectiva que es té dels vins espanyols a Estats Units. En aquest capítol s’analitzarà sobre tot la producció, el consum i les exportacions espanyoles i s’explicarà amb detall el concepte de denominacions d’origen.

Effect of the surface charge discretization on electric double layers. A Monte Carlo simulation study

The structure of the electric double layer in contact with discrete and continuously charged planar surfaces is studied within the framework of the primitive model through Monte Carlo simulations. Three different discretization models are considered together with the case of uniform distribution. The effect of discreteness is analyzed in terms of charge density profiles. For point surface groups,a complete equivalence with the situation of uniformly distributed charge is found if profiles are exclusively analyzed as a function of the distance to the charged surface. However, some differences are observed moving parallel to the surface. Significant discrepancies with approaches that do not account for discreteness are reported if charge sites of finite size placed on the surface are considered.

A reappraisal of 'International Stratigraphic Lexicon' and the need for the creation named units critical catalogues

Analysis of stratigraphic terminology and classification, shows that time-related stratigraphic units, which by definition have a global extent, are the concern of international cornrnissions and committees of the intemational Union of Geological Sciences (IUGS) . In contrast, lithostratigraphic, and other closely related units, are regional in extent and are catalogued in the International Stratigraphic Lexicon (ISL), the last volume of which, was published in 1987. Tlie intemational Commission on Stratigraphy (ICS) is currently attempting to revitalize the publication of ISL, given that the information contained in published volumes has never been updated, and that there has been a significant increase in stratigraphic research in recent decades. The proliferation of named units in the South Pyrenean and Ebro Basin Paleogene is evaluated to illustrate the extent of the problem. Moreover, new approaches to stratigraphic analysis have led to the naming of genetic units according to similar guidelines followed in the naming of descnptive or lithostratigraphic units. This has led to considerable confusion. The proposal to revitalize the ISL is accepted as part of the solution, that should also include the publication of critica1 catalogues, and the creation of norms for genetic unit terminology.

Chaotic dynamics of electric-field domains in periodically driven superlattices

Self-sustained time-dependent current oscillations under dc voltage bias have been observed in recent experiments on n-doped semiconductor superlattices with sequential resonant tunneling. The current oscillations are caused by the motion and recycling of the domain wall separating low- and high-electric-field regions of the superlattice, as the analysis of a discrete drift model shows and experimental evidence supports. Numerical simulation shows that different nonlinear dynamical regimes of the domain wall appear when an external microwave signal is superimposed on the dc bias and its driving frequency and driving amplitude vary. On the frequency-amplitude parameter plane, there are regions of entrainment and quasiperiodicity forming Arnold tongues. Chaos is demonstrated to appear at the boundaries of the tongues and in the regions where they overlap. Coexistence of up to four electric-field domains randomly nucleated in space is detected under ac+dc driving.
