Open Educational Resources: an opportunity for virtual learning institutions

The Universitat Oberta de Catalunya (UOC, Open University of Catalonia) is involved inseveral research projects and educational activities related to the use of Open Educational Resources (OER). Some of the discussed issues in the concept of OER are research issues which are being tackled in two EC projects (OLCOS and SELF). Besides the research part, the UOC aims at developing a virtual centre for analysing and promoting the concept of OERin Europe in the sector of Higher and Further Education. The objectives are to makeinformation and learning services available to provide university management staff,eLearning support centres, faculty and learners with practical information required to create, share and re-use such interoperable digital content, tools and licensing schemes. In the realisation of these objectives, the main activities are the following: to provide organisationaland individual e-learning end-users with orientation; to develop perspectives and useful recommendations in the form of a medium-term Roadmap 2010 for OER in Higher and Further Education in Europe; to offer practical information and support services about how to create, share and re-use open educational content by means of tutorials, guidelines, best practices, and specimen of exemplary open e-learning content; to establish a larger group ofcommitted experts throughout Europe and other continents who not only share theirexpertise but also steer networking, workshops, and clustering efforts; and to foster and support a community of practice in open e-learning content know-how and experiences.

Analyzing hidden semantics in social bookmarking of open educational resources

Web 2.0 services such as social bookmarking allow users to manage and share the links they find interesting, adding their own tags for describingthem. This is especially interesting in the field of open educational resources, asdelicious is a simple way to bridge the institutional point of view (i.e. learningobject repositories) with the individual one (i.e. personal collections), thuspromoting the discovering and sharing of such resources by other users. In this paper we propose a methodology for analyzing such tags in order to discover hidden semantics (i.e. taxonomies and vocabularies) that can be used toimprove descriptions of learning objects and make learning object repositories more visible and discoverable. We propose the use of a simple statistical analysis tool such as principal component analysis to discover which tags createclusters that can be semantically interpreted. We will compare the obtained results with a collection of resources related to open educational resources, in order to better understand the real needs of people searching for open educational resources.

Interactions with and through Mobile Phones: What about the Elderly Population?

This paper explores the distinctive characteristics of mobile telephone use among the elderly population using the most recent European country-level data on individual use of mobile telephony and advanced mobile services, Eurostat 2008. Through a cluster analysis of mobile phone use data across 30 countries, it is possible to confirm that mobile telephone occupies a peripheral position for the elderly in Europe.

An Empirical Study on Faculty Perceptions and Teaching Practices of Wikipedia

Some faculty members from different universities around the world have begun to use Wikipedia as a teaching tool in recent years. These experiences show, in most cases, very satisfactory results and a substantial improvement in various basic skills, as well as a positive influence on the students' motivation. Nevertheless and despite the growing importance of e-learning methodologies based on the use of the Internet for higher education, the use of Wikipedia as a teaching resource remains scarce among university faculty.Our investigation tries to identify which are the main factors that determine acceptance or resistance to that use. We approach the decision to use Wikipedia as a teaching tool by analyzing both the individual attributes of faculty members and the characteristics of the environment where they develop their teaching activity. From a specific survey sent to all faculty of the Universitat Oberta de Catalunya (UOC), pioneer and leader in online education in Spain, we have tried to infer the influence of these internal and external elements. The questionnaire was designed to measure different constructs: perceived quality of Wikipedia, teaching practices involving Wikipedia, use experience, perceived usefulness and use of 2.0 tools. Control items were also included for gathering information on gender, age, teaching experience, academic rank, and area of expertise.Our results reveal that academic rank, teaching experience, age or gender, are not decisive factors in explaining the educational use of Wikipedia. Instead, the decision to use it is closely linked to the perception of Wikipedia's quality, the use of other collaborative learning tools, an active attitude towards web 2.0 applications, and connections with the professional non-academic world. Situational context is also very important, since the use is higher when faculty members have got reference models in their close environment and when they perceive it is positively valued by their colleagues. As far as these attitudes, practices and cultural norms diverge in different scientific disciplines, we have also detected clear differences in the use of Wikipedia among areas of academic expertise. As a consequence, a greater application of Wikipedia both as a teaching resource and as a driver for teaching innovation would require much more active institutional policies and some changes in the dominant academic culture among faculty members.

Is It Possible to Predict the Manual Web Accessibility Result Using the Automatic Result?

The most adequate approach for benchmarking web accessibility is manual expert evaluation supplemented by automatic analysis tools. But manual evaluation has a high cost and is impractical to be applied on large websites. In reality, there is no choice but to rely on automated tools when reviewing large web sites for accessibility. The question is: to what extent the results from automatic evaluation of a web site and individual web pages can be used as an approximation for manual results? This paper presents the initial results of an investigation aimed at answering this question. He have performed both manual and automatic evaluations of the accessibility of web pages of two sites and we have compared the results. In our data set automatically retrieved results could most definitely be used as an approximation manual evaluation results.

Managing FOSS during development: preventive and curative approaches

Today, most software development teams use free and open source software (FOSS) components, because it increases the speed and the quality of the development. Many open source components are the de facto standard of their category. However, FOSS has licensing restrictions, and corporate organizations usually maintain a list of allowed and forbidden licenses. But how do you enforce this policy? How can you make sure that ALL files in your source depot, either belong to you, or fit your licensing policy? A first, preventive approach is to train and increase the awareness of the development team to these licensing issues. Depending on the size of the team, it may be costly but necessary. However, this does not ensure that a single individual will not commit a forbidden icon or library, and jeopardize the legal status of the whole release... if not the company, since software is becoming more and more a critical asset. Another approach is to verify what is included in the source repository, and check whether it belongs to the open-source world. This can be done on-the-fly, whenever a new file is added into the source depot. It can also be part of the release process, as a verification step before publishing the release. In both cases, there are some tools and databases to automate the detection process. We will present the various options regarding FOSS detection, how this process can be integrated in the "software factory", and how the results can be displayed in a usable and efficient way.

Forma Tarraconis: GIS aplicado a la arqueología urbana

Desde aquel incipiente interés renacentista del siglo XVI hasta la profesionalización de la arqueología en la actualidad, la ingente actividad realizada en Tarragona ha necesitado de formas de registrarla y organizarla, a fin de ser estudiada en el contexto diacrónico general de la ciudad. Esta tarea se ha visto favorecida en el último decenio del siglo pasado por la aparición y adopción de una herramienta informática que no fue diseñada específicamente para la Arqueología. El GIS o SIG, se ha convertido en un instrumento básico e indispensable para cualquier ciudad que tenga un mínimo bagaje patrimonial. Prueba de ello son las publicaciones de Cartas Arqueológicas obtenidas a partir de este software, o sin ir mucho más lejos, los trabajos presentados en este simposio. Presentamos a continuación la experiencia de Tarragona en la creación de un programa, bajo soporte GIS, para la gestión de la actividad arqueológica. Previamente contextualizaremos esta experiencia ya que es justa heredera de iniciativas individuales y de equipos y proyectos previos que trataron, con mucha menor suerte que no éxito, de organizar y poner orden en la maltrecha documentación arqueológica de nuestra ciudad. Describiremos posteriormente las funcionalidades básicas de este programa, su arquitectura y las aplicaciones realizadas en el desarrollo de sendos proyectos de estudio de la ciudad. En este último caso nos centraremos, principalmente, en el proyecto Planimetria Arqueològica de Tàrraco, impulsado por el Museu d’Història del Ayuntamiento de Tarragona y el Institut Català d’Arqueologia Clàssica, y que ha contado con la colaboración de la Generalitat de Catalunya para su edición. Seguidamente veremos como el uso de la información en capas registrada en el GIS combinada con la inclusión de la cartografía histórica de una ciudad permiten el análisis de problemas arqueológicos irresolubles sólo con los datos estrictamente arqueológicos. En este caso se aplicará sobre la validación de la morfología urbana de Tarraco propuesta por Macias (2000a). Por último se hará una reflexión sobre cuales podrían ser las mejoras aplicables sobre el programa, en previsión de futuras revisiones del mismo.

INDISIM-YEAST, an individual-based model to study yeast

INDISIM-YEAST, an individual-based simulator, models the evolution of a yeast population by settingup rules of behaviour for each individual cell according to their own biological rules and characteristics. Ittakes into account the uptake, metabolism, budding reproduction and viability of the yeast cells, over aperiod of time in the bulk of a liquid medium, occupying a three dimensional closed spatial grid with twokinds of particles (glucose and ethanol). Each microorganism is characterized by its biomass, genealogicalage, states in the budding cellular reproduction cycle and position in the space among others. Simulationsare carried out for population properties (global properties), as well as for those properties that pertain toindividual yeast cells (microscopic properties). The results of the simulations are in good qualitativeagreement with established experimental trends.

El llicenciat en ciències de l'activitat física i l'esport en el sistema sanitari

Els sistemes sanitaris dels països benestants s’enfronten cada dia a nous reptes generats per tot allò que prové de la salut individual i social. L’envelliment de la població i la manca d’exercici físic són dos factors que tenen una infl uència directa sobre la salut de les persones i que provoca que es plantegin noves logístiques i estructures dins els sistemes sanitaris per poder donar resposta a aquests factors. Són ben coneguts els benefi cis de l’exercici físic en la salut de les persones com a element preventiu i terapèutic. D’altra banda, l’exercici físic també està justifi cant i reivindicant la seva presència en el sistema sanitari, d’aquí la necessitat de crear la necessitat estructures i xarxes dins dels sistemes sanitaris que afavoreixin el treball de grups interdisciplinaris que integrin al llicenciat en ciències de l’activitat física i l’esport com a professional competent en la formació que ha rebut. L’aportació dels llicenciats en ciències de l’activitat física i l’esport en la prescripció d’exercici físic, conjuntament amb la resta de professionals com poden ser els facultatius, infermeria, fi sioterapeutes, entre d’altres, pot aportar benefi cis econòmics importants, sobretot pel que fa a l’estalvi en la despesa sanitària.

La humanización de las imágenens emitidas por la publicidad de los destinos monumentales: el caso de Girona

This article is based on the presentation of the results of a study on the humanisation of the image of cultural destinations, applied to the case of the city of Girona. According to the theories raised by different authors, we were interested in analyzing if the tourist images shown by the tourists publicity are influenced by romantic references typical of the dynamics of individual consumption. That is to say, if these images project a vision of an empty city, a museum.city, an individual panoramic or an individual consumption experience. The results of the analysis allow us to affirm that a mythical image of the city exists and it has a clearly romantic origin. Nevertheless, on the other hand, a specific glance exists where the tension between the indivudual freedom and the social conventionalism is demonstrated

Systems medicine and integrated care to combat chronic noncommunicable diseases

We propose an innovative, integrated, cost-effective health system to combat major non-communicable diseases (NCDs), including cardiovascular, chronic respiratory, metabolic, rheumatologic and neurologic disorders and cancers, which together are the predominant health problem of the 21st century. This proposed holistic strategy involves comprehensive patient-centered integrated care and multi-scale, multi-modal and multi-level systems approaches to tackle NCDs as a common group of diseases. Rather than studying each disease individually, it will take into account their intertwined gene-environment, socio-economic interactions and co-morbidities that lead to individual-specific complex phenotypes. It will implement a road map for predictive, preventive, personalized and participatory (P4) medicine based on a robust and extensive knowledge management infrastructure that contains individual patient information. It will be supported by strategic partnerships involving all stakeholders, including general practitioners associated with patient-centered care. This systems medicine strategy, which will take a holistic approach to disease, is designed to allow the results to be used globally, taking into account the needs and specificities of local economies and health systems.
