El impacto de las TIC en la empresa turística : el caso de Cataluña

En aquest article s'aporten proves de l'impacte positiu que té l'aplicació de les tecnologies de la informació i la comunicació (TIC) en l'empresa turística catalana. La transcendència que en els darrers anys ha adquirit el mercat turístic català en el context europeu el converteix en un laboratori d'anàlisi idoni per al sector. Els resultats obtinguts posen de manifest que l'ús d'aquestes tecnologies s'acompanya d'un major grau d'internacionalització de l'empresa, el desenvolupament de canvis organitzatius i la implantació de noves estratègies competitives, cosa que dóna lloc a un model de negoci allunyat de les concepcions tradicionals del sector. A més, l'ús estratègic de les TIC afavoreix l'ús de mà d'obra més qualificada, un servei més personalitzat i una major proximitat a proveïdors i distribuïdors. Tanmateix, és en el procés d'innovació empresarial on l'impacte positiu de les TIC és percep més, atès que el seu ús ha contribuït a superar alguns dels obstacles existents, a interioritzar el procés en el si de l'empresa i a fer més partícips els mateixos treballadors, i això ha donat com a resultat una àmplia diversitat d'innovacions de tota mena (de producte, de procés i organitzatives). La participació en xarxes de cooperació, el fet de tenir treballadors amb un nivell educatiu elevat i l'aplicació intensiva de les TIC han estat elements indispensables en aquest procés innovador. Finalment, gràcies a l'ús de les TIC i el seu impacte en la innovació, però també al canvi organitzatiu dins l'empresa, s'han millorat els registres de productivitat, amb la qual cosa s'afavoreix una major competitivitat en un context canviant i de forta pressió de l'entorn.

Molecular changes underlying mammalian phenotypic innovation

Mammals are characterized by specific phenotypic traits that include lactation, hair, and relatively large brains with unique structures. Individual mammalian lineages have, in turn, evolved characteristic traits that distinguish them from others. These include obvious anatom¬ical differences but also differences related to reproduction, life span, cognitive abilities, be¬havior. and disease susceptibility. However, the molecular basis of the diverse mammalian phenotypes and the selective pressures that shaped their evolution remain largely unknown. In the first part of my thesis, I analyzed the genetic factors associated with the origin of a unique mammalian phenotype lactation and I studied the selective pressures that forged the transition from oviparity to viviparity. Using a comparative genomics approach and evolutionary simulations, I showed that the emergence of lactation, as well as the appear¬ance of the casein gene family, significantly reduced selective pressure on the major egg-yolk proteins (the vitellogenin family). This led to a progressive loss of vitellogenins, which - in oviparous species - act as storage proteins for lipids, amino acids, phosphorous and calcium in the isolated egg. The passage to internal fertilization and placentation in therian mam¬mals rendered vitellogenins completely dispensable, which ended in the loss of the whole gene family in this lineage. As illustrated by the vitellogenin study, changes in gene content are one possible underlying factor for the evolution of mammalian-specific phenotypes. However, more subtle genomic changes, such as mutations in protein-coding sequences, can also greatly affect the phenotypes. In particular, it was proposed that changes at the level of gene reg¬ulation could underlie many (or even most) phenotypic differences between species. In the second part of my thesis, I participated in a major comparative study of mammalian tissue transcriptomes, with the goal of understanding how evolutionary forces affected expression patterns in the past 200 million years of mammalian evolution. I showed that, while com¬parisons of gene expressions are in agreement with the known species phylogeny, the rate of expression evolution varies greatly among lineages. Species with low effective population size, such as monotremes and hominoids, showed significantly accelerated rates of gene expression evolution. The most likely explanation for the high rate of gene expression evolution in these lineages is the accumulation of mildly deleterious mutations in regulatory regions, due to the low efficiency of purifying selection. Thus, our observations are in agreement with the nearly neutral theory of molecular evolution. I also describe substantial differences in evolutionary rates between tissues, with brain being the most constrained (especially in primates) and testis significantly accelerated. The rate of gene expression evolution also varies significantly between chromosomes. In particular, I observed an acceleration of gene expression changes on the X chromosome, probably as a result of adaptive processes associated with the origin of therian sex chromosomes. Lastly, I identified several individual genes as well as co-regulated expression modules that have undergone lineage specific expression changes and likely under¬lie various phenotypic innovations in mammals. The methods developed during my thesis, as well as the comprehensive gene content analyses and transcriptomics datasets made available by our group, will likely prove to be useful for further exploratory analyses of the diverse mammalian phenotypes.

@neurIST infrastructure for advanced disease management through integration of heterogeneous data, computing, and complex processing services

The increasing volume of data describing humandisease processes and the growing complexity of understanding, managing, and sharing such data presents a huge challenge for clinicians and medical researchers. This paper presents the@neurIST system, which provides an infrastructure for biomedical research while aiding clinical care, by bringing together heterogeneous data and complex processing and computing services. Although @neurIST targets the investigation and treatment of cerebral aneurysms, the system’s architecture is generic enough that it could be adapted to the treatment of other diseases.Innovations in @neurIST include confining the patient data pertaining to aneurysms inside a single environment that offers cliniciansthe tools to analyze and interpret patient data and make use of knowledge-based guidance in planning their treatment. Medicalresearchers gain access to a critical mass of aneurysm related data due to the system’s ability to federate distributed informationsources. A semantically mediated grid infrastructure ensures that both clinicians and researchers are able to seamlessly access andwork on data that is distributed across multiple sites in a secure way in addition to providing computing resources on demand forperforming computationally intensive simulations for treatment planning and research.

Stock returns, term structure, inflation and real activity: An international perspective

This paper analyses the empirical interdependences among assetreturns, real activity and inflation from a multicountry and internationalpoint of view. We find that nominal stock returns are significantly relatedto inflation only in the US, that the US term structure of interest ratespredicts both domestic and foreign inflation rates while foreign termstructures do not have this predictive power and that innovations in inflationand exchange rates induce insignificant responses of real and financialvariables. An interpretation of the dynamics and some policy implicationsof the results are provided.

Aplicación de realidad aumentada para dispositivos móviles destinada a espacios culturales. Ejemplo de desarrollo: Museu Episcopal de Vic

Proyecto de aplicación para dispositivos móviles que utiliza la Realidad Aumentada (RA) para contextualizar obras artísticas. Es un producto pensado para museos y galerías pero también para espacios exteriores que posean elementos de valor cultural. Sin embargo, y para servir de ejemplo se ha aplicado en seis piezas destacadas del Museo Episcopal de Vic. Aunque en Europa y EE.UU. los museos ya están innovando en este terreno, en España, que es donde se enmarca el proyecto, existe una carencia de elementos de mediación cultural como estos; sobre todo en los museos de arte donde las obras acostumbran a presentarse despojadas de cualquier herramienta que proporcione información complementaria. Existe, por tanto, una descontextualización del arte que crea barreras para el entendimiento del público general. De esta situación de carencia parte el objetivo principal del producto, el de aprovechar las posibilidades de la RA para mejorar la experiencia y el diálogo entre el visitante y la obra, aportando conocimiento y fomentando el aprendizaje.

L'arthroplastie totale de genou: évolution et résultats actuels

Avec 95% de bons résultats à 10 ans, on peut considérer aujourd'hui que l'arthroplastie totale du genou est un traitement fiable des gonarthroses chez des patients âgés à demande fonctionnelle raisonnable. Les quatre complications potentielles principales après la mise en place d'une prothèse totale du genou sont le descellement aseptique, l'infection, le manque de flexion et les douleurs persistantes. En cas de problème avec une prothèse totale du genou, il faut toujours exclure la présence d'une infection avant d'envisager une autre raison. Les innovations actuelles en arthroplastie du genou doivent viser à améliorer les résultats chez les patients jeunes et actifs i.e. tant au niveau de la conception des nouveaux implants, voire des matériaux plus résistants, que des techniques chirurgicales elles-mêmes. Total knee arthroplasty: current advances and results With a 95% success rate at 10 years, total knee arthroplasty can be regarded today as a reliable way of treating knee osteoarthritis in elderly patients with reasonable functional demands. The four main potential complications after placing of a total knee prosthesis are aseptic loosening, infection, lack of flexion and persistent pain. If a problem arises with a total knee prosthesis, infection must always be ruled out before considering other causes. Current innovations in knee arthroplasty should be aimed at improving results in young and active patients, i.e. in regard to both the design of new implants, or tougher materials, and to the surgical techniques themselves.

High-grade gliomas: reality and hopes.

In this issue of the Chinese Journal of Cancer, European experts review current standards, trends, and future prospects in the difficult domain of high-grade glioma. In all fields covered by the different authors, the progress has been impressive. For example, discoveries at the molecular level have already impacted imaging, surgery, radiotherapy, and systemic therapies, and they are expected to play an increasing role in the management of these cancers. The European Organization for Research and Treatment of Cancer (EORTC) has pioneered new treatment strategies and contributed to new standards. The articles in this issue will cover basic molecular biological principles applicable today, novel surgical approaches, innovations in radiotherapy planning and delivery, evidence-based standards for radiotherapy alone or combined with chemotherapy, current standards and novel approaches for systemic treatments, and the important but often neglected field of health-related quality of life. Despite the advances described in these articles, the overall prognosis of high-grade glioma, especially glioblastoma, remains poor, and more research is needed to address this problem.

06034-016 Lake Colchester/Middle Creek Watershed Final Report

In-lake management can be a critical need for water quality improvement for impaired recreation lakes. Biomanipulation practices to achieve the proper balance of predatory fish, zooplankton grazing of algae, and native aquatic vegetation can sometimes restore water clarity of turbid, nutrient enriched lakes. Lakewood leaders have a renovation plan for Lake Colchester, involving several common and three innovative practices. Lakewood is prepared to pay for proven practices, but seeks WIRB grant support to test innovations in collaboration with Iowa DNR biologists, and ISU limnologists, serving as advisors and monitors for the entire project.

The expansion of international standardization has reinforced enduring questions on the legitimacy of standards. In that respect, the participation of all stakeholders, including the weakest ones (unions, NGO, consumers' associations) is crucial. Given the recognized role of consumers' associations to express legitimate objectives, the question of their representation becomes central. In order to get a deeper understanding of their participation, this article explores the evolution of their representation within the Swiss national mirror committees of international standardization between 1987 and 2007. It probes the extent to which their participation is determined by the distinctiveness of issues supposedly related to consumers' concerns and by their own use of standards. The empirical findings of our study indicate an underrepresentation of consumers' associations and confirm the topical specificity of their implication in standardization processes. Finally, we found evidence that the use of standards in an association's activities supports and encourages its participation in standardization committees.

Innovaatiojohtaminen ja sen vaikutuksia metsäteollisuudessa

Työn tavoitteena on selvittää metsäteollisuuden innovaatiotoiminnan johtamisprosessia ja sen vaikutuksia yksittäisissä innovaatioissa. Tarkoituksena on tuoda esiin uutta tietoa metsäteollisuuden innovaatiotoiminnan nykytilasta, innovaatiojohtamisesta ja sen merkittävimmistä tekijöistä, sekä analysoida tätä tietoa toiminnan kehittämiseksi. Yrityshaastattelujen avulla työssäselvitetään johtamisprosessia ja sen toimintoja, sekä siihen vaikuttavia sisäisiä ja ulkoisia tekijöitä. Innovaatiojohtamisen vaikutuksista tutkitaan kaupallistettujen innovaatioiden kehitysaikoja ja eri yhteistyösuhteiden merkitystä SIN-mallin (System Integration and Networking) mukaan. Työssä havaittiin, että metsäteollisuusyritykset ovat viime vuosina jossain määrin alkaneet kehittää innovaatiotoimintaansa, mutta systemaattisempi innovaatioprosessi ja selkeät strategiset suuntaukset toiminnan ohjaamiseen ja prosessin hallintaan puuttuvat. Innovaatiotoiminnan epäjärjestelmällisyyteen vaikuttaa ristiriita eri aikavälien tavoitteissa: toisaalta yritykset tavoittelevat nopeasti kustannustehokkuutta ja toisaaltapitkäjänteisempää uudistumista. Tärkeimpiä yhteistyökumppaneita innovaatiotoiminnassa ovat asiakkaat, alihankkijat ja toimittajat. Verkostoituminen, innovaatioprosessin tehokkuus ja kyky tuottaa menestyviä innovaatioita korostuvat tulevaisuudessa. Lisäksi innovaatiojohtamisella on tuettava innovaatioiden lähteitä ja radikaalimpia innovaatioita, sekä pyrittävä alentamaan muutosvastarintaa.
