Aquest estudi aplica la Teoria de l‟Autodeterminació (Deci i Ryan, 1985, 2000, 2002) i el constructe motivacional d‟Engagement (Schaufeli, Martínez, Marqués, Salanova i Bakker, 2002; Schaufeli, Salanova, González-Roma i Bakker, 2002) per investigar els efectes de la regulació motivacional dels estudiants, l‟Engagement, la Competència percebuda i la Vinculació sobre les Expectatives Acadèmiques i Laborals, la Satisfacció i el Rendiment acadèmic. Els resultats revelen que: (1) els 214 estudiants de Psicologia de la Universitat de Girona que varen participar en la recerca mostren alts nivells d‟autonomia (Regulació Identificada i Intrínseca), però nivells moderats d‟Engagement (Vigor i Absorció, i una mica més alts de Dedicació); (2) les intercorrelacions entre totes les variables motivacionals considerades confirmen les prediccions de la Teoria de l‟Autodeterminació i del model motivacional de l‟Engagement; (3) la Competència percebuda prediu les Expectatives Acadèmiques, mentre que la Motivació Intrínseca i l‟Engagement prediuen les Expectatives Laborals; (4) l‟Amotivació i el Cinisme (en sentit negatiu) i la Motivació Intrínseca i l‟Engagement (en positiu) prediuen la Satisfacció amb la carrera; i (5) l‟Amotivació (en negatiu) i la Competència percebuda (en positiu) prediuen el Rendiment acadèmic

This article reports on a project at the Universitat Oberta de Catalunya (UOC: The Open University of Catalonia, Barcelona) to develop an innovative package of hypermedia-based learning materials for a new course entitled 'Current Issues in Marketing'. The UOC is a distance university entirely based on a virtual campus. The learning materials project was undertaken in order to benefit from the advantages which new communication technologies offer to the teaching of marketing in distance education. The article reviews the main issues involved in incorporating new technologies in learning materials, the development of the learning materials, and their functioning within the hypermedia based virtual campus of the UOC. An empirical study is then carried out in order to evaluate the attitudes of students to the project. Finally, suggestions for improving similar projects in the future are put forward.

Treball Final de Carrera ( TFC ) consistent en l'anàlisi de diferents tipus d'estratègies que les empreses poden aplicar centrant-se en les idees de Michael Porter i el desenvolupament d'aquestes idees per part de diferents professionals. El TFC està dividit en dos blocs, un de teòric i un de pràctic. El primer bloc consisteix en l'anàlisi dels diferents tipus d'estratègies derivades de les idees de Michael Porter. En aquest primer bloc, hem analitzat com a través del model de les cinc forces, Porter va arribar a les estratègies genèriques. Després hem analitzat les tres estratègies genèriques conjuntament amb l'estratègia híbrida i amb l'Estratègia de l'Oceà Blau. El segon bloc està format per diversos casos pràctics d'empreses que han aconseguit l'èxit durant l'actual període de crisi en els diferents sectors de l'economia. Aquestes empreses són Yoigo com a exemple de baix cost , Starbucks com implementació d'una estratègia de diferenciació i Ryan Air exemplificant una estratègia de segmentació enfocada als baixos costos. Finalment, hem analitzat a Toyota degut a la seva estratègia híbrida i Graphenea com una companyia que implementa Estratègia de l'Oceà Blau. Totes aquestes companyies han aconseguit l'èxit durant l'actual període de crisi. El motiu és que aquestes empreses van escollir un tipus d'estratègia d'acord amb l'estructura de la indústria en la qual operen. No obstant això, la implementació d'aquestes estratègies no assegura resultats d'èxit. L'adequada aplicació d'aquestes estratègies suposa per a les empreses una demostració de que aconseguir l'èxit durant períodes de recessió econòmica és possible, vinculat a una bona gestió estratègica.

To evaluate the avian influenza virus (AIV) circulation in Antarctic and sub-Antarctic penguins we carried out a serosurvey on six species from Livingston, Marion and Gough islands. Seropositivity against AIV was performed on serum samples using a competitive enzyme-linked immunosorbent assay and haemagglutination and neuraminidase inhibition assays. Some oropharyngeal and cloacal swabs were also assayed to detect influenza virus genomes by real time reverse transcription-polymerase chain reaction. Overall, 12.1% (n = 140) penguins were seropositive to AIV. By species, we detected 5% (n = 19) and 11% (n = 18) seroprevalence in sub-Antarctic rockhopper penguins (Eudyptes spp.) from Gough and Marion islands, respectively, 42% (n = 33) seroprevalence in macaroni penguins (Eudyptes chysolophus Brandt), but no positives in the three other species, gentoo (Pygoscelis papua Forster; n = 25) and chinstrap penguins (P. antarctica Forster; n = 16), from Livingston Island and king penguins (Aptenodytes patagonicus Miller; n = 27) from Marion Island. While seropositivity reflected previous exposure to the AIV, the influenza genome was not detected. Our results indicate that AIV strains have circulated in penguin species in the sub-Antarctic region, but further studies are necessary to determine the precise role that such penguin species play in AIV epidemiology and if this circulation is species (or genus) specific.

Seabirds are facing a growing number of threats in both terrestrial and marine habitats, and many populations have experienced dramatic changes over past decades. Years of seabird research have improved our understanding of seabird populations and provided a broader understanding of marine ecological processes. In an effort to encourage future research and guide seabird conservation science, seabird researchers from 9 nations identified the 20 highest priority research questions and organized these into 6 general categories: (1) population dynamics, (2) spatial ecology, (3) tropho-dynamics, (4) fisheries interactions, (5) response to global change, and (6) management of anthropogenic impacts (focusing on invasive species, contaminants and protected areas). For each category, we provide an assessment of the current approaches, challenges and future directions. While this is not an exhaustive list of all research needed to address the myriad conservation challenges seabirds face, the results of this effort represent an important synthesis of current expert opinion across sub-disciplines within seabird ecology. As this synthesis highlights, research, in conjunction with direct management, education, and community engagement, can play an important role in facilitating the conservation and management of seabird populations and of the ocean ecosystems on which they and we depend.

BACKGROUND: The World Mental Health Survey Initiative (WMHSI) has advanced our understanding of mental disorders by providing data suitable for analysis across many countries. However, these data have not yet been fully explored from a cross-national lifespan perspective. In particular, there is a shortage of research on the relationship between mood and anxiety disorders and age across countries. In this study we used multigroup methods to model the distribution of 12-month DSM-IV/CIDI mood and anxiety disorders across the adult lifespan in relation to determinants of mental health in 10 European Union (EU) countries. METHOD: Logistic regression was used to model the odds of any mood or any anxiety disorder as a function of age, gender, marital status, urbanicity and employment using a multigroup approach (n = 35500). This allowed for the testing of specific lifespan hypotheses across participating countries. RESULTS: No simple geographical pattern exists with which to describe the relationship between 12-month prevalence of mood and anxiety disorders and age. Of the adults sampled, very few aged ≥ 80 years met DSM-IV diagnostic criteria for these disorders. The associations between these disorders and key sociodemographic variables were relatively homogeneous across countries after adjusting for age. CONCLUSIONS: Further research is required to confirm that there are indeed stages in the lifespan where the reported prevalence of mental disorders is low, such as among younger adults in the East and older adults in the West. This project illustrates the difficulties in conducting research among different age groups simultaneously.
