The deployment of an e-book consultation and loan service : the experience of the Open University of Catalonia Library

La Biblioteca de la UOC (UOC Library) ha ofert durant tres mesos (octubre-desembre 09), en fase de prova pilot, un servei de consulta i préstec de lectors de llibres electrònics (e-readers). Aquest nou desplegament s'ha desenvolupat en consonància amb l'aposta general de la Universitat en innovació en tecnologies aplicades a l'educació, i la voluntat de potenciar les col·leccions de llibres electrònics i l'ús dels dispositius de lectura de llibres electrònics com una extensió més de la tecnologia del Campus 5.0, en el suport a l'aprenentatge dels seus estudiants durant la seva formació a la Universitat. Aquest treball presenta en detall les especificacions de la prova pilot, a més de contenir una anàlisi i avaluació dels resultats obtinguts: punts forts i punts febles, relació dels aspectes a millorar i modificar, de cara a la consolidació final del servei.

T-Coffee: a web server for the multiple sequence alignment of protein and RNA sequences using structural information and homology extension

This article introduces a new interface for T-Coffee, a consistency-based multiple sequence alignment program. This interface provides an easy and intuitive access to the most popular functionality of the package. These include the default T-Coffee mode for protein and nucleic acid sequences, the M-Coffee mode that allows combining the output of any other aligners, and template-based modes of T-Coffee that deliver high accuracy alignments while using structural or homology derived templates. These three available template modes are Expresso for the alignment of protein with a known 3D-Structure, R-Coffee to align RNA sequences with conserved secondary structures and PSI-Coffee to accurately align distantly related sequences using homology extension. The new server benefits from recent improvements of the T-Coffee algorithm and can align up to 150 sequences as long as 10 000 residues and is available from both http://www.tcoffee.org and its main mirror http://tcoffee.crg.cat.

External sources of innovation and industry-university interaction:evidence from Spanish firms

This paper is about the firm innovation process and the cooperation of the innovative firms with other firms and public institutions. A special attention is paid to the cooperation with universities. We use the Technological Innovation Survey (TIS) from the Instituto Nacional de Estadística (Spain) in order to obtain data for 4,159 innovative firms. Our results show that firm's cooperation activities are closely linked to the characteristics of the industry and the firm as well as to the origin of public funds for R&D activities. Key words: Innovation, universities, Spanish economy. JEL code: O31, I20, L60

Sabbatical stay at CREVER, University Rovira i Virgili

A three-year research proposal of international impact and quality was developed between the author and CREVER researchers, taking into account the infrastructure and research lines already being carried out at CREVER. The project is related to the study of new mixtures in thermal activated systems, by the addition of a third component to help the heat transfer processes. The project proposes the use of water and lithium nitrate as absorbents in ternary ammonia mixtures, varying the concentration with the objective of optimising the mixture for solar air conditioning purposes. Also, the research proposal will promote an intensive collaboration in the following years between CREVER and The Centro de Investigación en Energía-UNAM, Mexico.

Not all university degrees yield the same return: private and social returns to higher education for males in Spain

In this paper we use micro data from the Spanish Family Expenditure Survey for 1990 to estimate, for the first time, the private and social rates of return of different university degrees in Spain. We compute internal rates of return and include investment on higher education financed by the public purse to estimate social rates of return. Our main finding is that, as presumed, there is large heterogeneity in rates of return amongst different university

Por una parte, se trata la historia del feminismo anglosajón respecto a sus visiones sobre la prostitución, desde una aproximación a las fuentes. Por otra parte, se plantea la situación jurídico-política. Finalmente, se presenta brevemente a las principales entidades que dan apoyo al colectivo de trabajadoras del sexo en la ciudad de Londres.

Technological trampolines for new venture creation in Catalonia: the case of the University of Girona

Recent trends in technology transfer show an intensification of spin-off creation as a modality of university research commercialisation, complementary to the conventional ones, contract research and licensing. In this paper we analyse the evolution, objectives, resources and activities of a specialised unit –Technological Trampoline (TT) - in charge of new venture creation at the University of Girona (Catalonia-Spain). Based on two theoretical frameworks, Resource-based-view and Institutional Theory, we adopt a multi-dimensional approach to study the strategy of spinning-off new ventures at the University of Girona in terms of resources and activities, how this process is organised and if the outputs fit with this UdG’s objectives and the local environment. Our main contribution is an in-depth analysis of the spin-off creation unit with special emphasis on its variety of resources and activities. The results have a series of implications and recommendations at both university and TT level.

Galois extension of CP-Graded ring extensions

In this paper, we investigate galois theory of CP-graded ring extensions. In particular, we generalize some galois results given in [1, 2] and, without restriction to nor graded fields nor torsion free of the grade groups, we show that some results of graded field extensions given in [3] hold.

Label Space Reduction in All-Optical Label Switchiing Networks

Report for the scientific sojourn at the Department of Information Technology (INTEC) at the Ghent University, Belgium, from january to june 2007. All-Optical Label Swapping (AOLS) forms a key technology towards the implementation of All-Optical Packet Switching nodes (AOPS) for the future optical Internet. The capital expenditures of the deployment of AOLS increases with the size of the label spaces (i.e. the number of used labels), since a special optical device is needed for each recognized label on every node. Label space sizes are affected by the wayin which demands are routed. For instance, while shortest-path routing leads to the usage of fewer labels but high link utilization, minimum interference routing leads to the opposite. This project studies and proposes All-Optical Label Stacking (AOLStack), which is an extension of the AOLS architecture. AOLStack aims at reducing label spaces while easing the compromise with link utilization. In this project, an Integer Lineal Program is proposed with the objective of analyzing the softening of the aforementioned trade-off due to AOLStack. Furthermore, a heuristic aiming at finding good solutions in polynomial-time is proposed as well. Simulation results show that AOLStack either a) reduces the label spaces with a low increase in the link utilization or, similarly, b) uses better the residual bandwidth to decrease the number of labels even more.

Tot repensant els serveis bibliogràfics a la University of California

Informe d'un Grup de Treball sobre Serveis Bibliogràfics de la University of California que presenta un seguit de recomanacions sobre els canvis que aquests serveis haurien d'implementar per millorar les seves prestacions. Els autors posen de manifest el desfasament que pateixen bona part dels serveis bibliotecaris actuals davant les prestacions que ofereixen portals com Amazon o Google. Les recomanacions s'estructuren en quatre apartats: millorar la cerca i la recuperació, redissenyar l'OPAC, adoptar noves pràctiques catalogràfiques i donar suport a la millora continua. L'informe finalitza amb l'enumeració d'una seixantena de possibles actuacions addicionals que també es van considerar i les raons per les quals finalment es van descartar.

An extension of the Marsden-Ratiu reduction for Poisson manifolds

We propose a generalization of the reduction of Poisson manifolds by distributions introduced by Marsden and Ratiu. Our proposal overcomes some of the restrictions of the original procedure, and makes the reduced Poisson structure effectively dependent on the distribution. Different applications are discussed, as well as the algebraic interpretation of the procedure and its formulation in terms of Dirac structures.

Memòria justificativa del treball realitzat durant l'estada a la University of California at Los Angeles (UCLA)

Projecte de recerca elaborat a partir d’una estada a la Graduate School of Education and Information Studies (GSEIS) de la University of California at Los Angeles (UCLA), Estats Units, entre gener i juny del 2007. En el context d’elaboració d’una futura tesi doctoral sobre la metodologia comunicativa crítica i la interacció persona-ordinador, la intenció ha estat aprofundir des d'una perspectiva internacional. La GSEIS i la UCLA en general conta amb innumerables recursos bibliogràfics així com amb professorat de reconegut prestigi internacional en la recerca vinculada a la barreja de temes com l'educació, la inclusió i la transformació social, la Comunicació, les TIC i el disseny de la Interacció Persona Ordinador; integració de disciplines en la que es mou la meva tesi doctoral. La possibilitat d'accedir a la Young Research Library, així com l'assistència a diverses conferències relacionades amb el meu àmbit d'estudi, la celebració de diverses tutories amb professorat de la GSEIS i d'altres departaments de la UCLA, i la invitació a participar del seminari de doctorat del professor Douglas Kellner, han contribuït de forma remarcable al meu projecte amb: aportacions de la literatura internacional i nombrosos exemples de bones pràctiques de projectes vinculats al Participatory Design com a metodologia en si mateixa desvinculada del Disseny Centrat en l'Usuari, un dels aspectes centrals de la meva tesi. Amb tot això vaig poder reforçar i desenvolupar quatre dels capítols de la meva dissertació, concretament els relacionats amb el context social i metodològic, i els que presenten el disseny de la Interacció Persona ordinador des d'un enfocament general així com el que es centra en el Disseny participatiu i les seves vinculacions amb la metodologia comunicativa crítica.
