Uso de ODR en las comunidades de desarrollo de software libre

La revolució del programari lliure ha estat i és un dels fenòmens més imprevisibles i de major abast que han sorgit des del desenvolupament de les Tecnologies de la Informació. No obstant això és un fenomen que, a causa de pròpia construcció social i distribuïda, està intrínsecament unit a la noció de conflicte, la manifestació del qual més notòria és la bifurcació o fork. En el present treball analitzem els diferents tipus de conflictes i els mecanismes habitualment emprats per a la resolució dels mateixos, i si formen part dels denominats mètodes alternatius de resolució de controvèrsies en Línia o ODR o si són part d'una categoria diferent i separada.

Sistemas de Información BI: Estado Actual y Herramientas de Software Libre

Actualmente muchas empresas ya sean grandes o pequeñas, se plantean implantar en su organización un sistema de información que les ayude en la toma de decisiones. Una de las tendencias actuales es implantar un sistema de BI (Business Intelligence). Muchas organizaciones implantan este tipo de sistemas sin haber realizado un estudio previo de las necesidades y problemas de la empresa, de los beneficios que se pretenden obtener con la implantación del sistema, de la aceptación y formación de los usuarios, de las herramientas y proveedores de BI,... y así un largo etcétera de situaciones y condiciones que se deberían tener en cuenta para la implantación de esta clase de sistemas en cualquier tipo de organización, ya sea grande o pequeña.En el presente artículo se realiza una síntesis de la amalgama de información existente en los sistemas de BI, se realiza una definición aclaratoria, así como también se expone su estado actual, beneficios, factores de riesgo, pasos para conseguir una implantación exitosa y los componentes y herramientas open source de los sistemas de BI. Primero se exponen las principales herramientas open source existentes en el mercado y se profundiza más especialmente en la Suite open source de BI Pentaho.

Fonaments d'un programa informàtic de suport psicològic i superació personal : dels llibres d'autoajuda al software d'autoajuda

Aquest treball descriu els principis de disseny i els components essencials d'un hipotètic programa informàtic que té per finalitat facilitar el procés d'autoajuda i que també pot ser utilitzat com a eina de desenvolupament personal i motivació. Prèviament, l'autor fa una revisió dels mètodes existents, des de l'èxit dels llibres d'autoajuda del segle XX fins al'expansió de la interactivitat impulsada pel desenvolupament de les tecnologiesinformàtiques. A través d'aquest recorregut es constata la pobre implantació de les novestecnologies com a instruments populars d'autoajuda i s'advoca per la creació i ús deprogrames informàtics flexibles i generalistes com a mitjà de suport psicològic.

Free Technology Academy : a Joint Venture of Free Software and OER

The decision to publish educational materials openly and under free licenses brings up the challenge of doing it in a sustainable way. Some lessons can be learned from the business models for production, maintenance and distribution of Free and Open Source Software. The Free Technology Academy (FTA) has taken on these challenges and has implemented some of these models. We briefly review the FTA educational programme, methodologies and organisation, and see to which extent these models are proving successful in the case of the FTA.

Approaches to OER Development

OER development is becoming more sophisticated as instructors and course specialists become more familiar with the environment. Most OER development approaches for online courses have been developed from those that were appropriate in the face-to-face context. However, the OER online environment opens up new possibilities for learning as well as holding particular limitations. This paper presents some approaches that OER implementers should bear in mind when initiating and supporting OER course development projects.1. Beg, borrow, or steal courseware. Don't reinvent the wheel.2. Take what exists and build the course around it.3. Mix and match. Assemble. Don't create.4. Avoid the "not invented here" syndrome. 5. Know the content -garbage in and garbage out.6. Establish deadlines. Work to deadlines, but don't be unrealistic. 7. Estimate your costs and then double them. Double them again. 8. Be realistic in scheduling and scoping.9. The project plan must be flexible. Be prepared for major shifts.10. Build flexibly for reuse and repurposing -generalizability reduces costs 11. Provide different routes to learning. 12. Build to international standards.There are necessary features in every OER, including introduction, schedule etc. but it is most important to keep the course as simple as possible. Extreme Programming (XP) methodology can be adapted from software engineering to aid in the course development process.

COINE Project : Cultural Objects in Networked Environments

La idea subjacent al Projecte de Recerca i Desenvolupament COINE és permetre a la gent contar les seves pròpies històries. COINE pretén proporcionar les eines necessàries per crear estructuradament, un entorn basat en el World Wide Web, que permeti compartir continguts. Els resultats del Projecte ajudaran al desenvolupament d'estàndards per a la implantació i la recuperació estructurades de recursos digitals en entorns en xarxa distribuïda. El Projecte de COINE s'inicià el març de 2002 i finalitzà l'agost de 2004. Avui en dia estem al WorkPackage 5 on estem construint el Sistema, el programari i les interfícies. COINE pretén cobrir la gamma més àmplia possible d'usuaris potencials, des d'organitzacions de patrimoni cultural i institucions de qualsevol mida (principalment biblioteques, arxius i museus) fins a individus de qualsevol edat sense habilitats en l'ús de les TIC, o a grups petits de ciutadans. Els usuaris no utilitzaran només COINE com a eina de cerca, sinó que contribuiran amb el seu propi contingut.

Entorno Colaborativo de Trabajo: La Intranet 2.0 de la Consejería de Salud de la Junta de Andalucía

The Department of Health of the Government of Andalusia provides professionals of the Andalusian Public Health Care System a collaborative working environment (Entorno colaborativo de trabajo [ECT]) based on the principles of web 2.0. The ECT is organized into communities, understood as sets of people with a common interest who share a space with its own information and collaboration tools. This space is managed and powered autonomously by the communities themselves. This paper analyzes the use and degree of implementation of the ECT, considering the user communities and activity statistics in 2009 and 2010. From the data obtained we deduce that instrumental services have easier acceptance than collaboration and knowledge management services; content generation is focused on a small number of users; and communities associated with organizational units have less development than those associated with work areas or projects.

What should a virtual University Library environment look like?

Over the past year, the Open University of Catalonia library has been designing its new website with this question in mind. Our main concern has been how to integrate the library in the student day to day study routine to not to be only a satellite tool. We present the design of the website that, in a virtual library like ours, it is not only a website but the whole library itself. The central point of the web is my library, a space that associates the library resources with the student's curriculum and their course subjects. There the students can save the resources as favourites, comment or share them. They have also access to all the services the library offers them. The resources are imported from multiple tools such as Millennium, SFX, Metalib and Dspace to the Drupal CMS. Then the resources' metadata can be enriched with other contextual information from other sources, for example the course subjects. And finally they can be exported in standard, open data formats making them available for linked data applications.

ACCEDA y BUSTREAMING : Integración de audio y video en el proceso de autoarchivo del Repositorio de la ULPGC en acceso abierto

Presentació de les dues noves plataformes desenvolupades per la Biblioteca de la Universitat de Las Palmas de Gran Canaria: ACCEDA (documentació científica de la ULPGC en accés obert) i BUSTREAMING (documentació multimèdia). Aquestes són dues noves iniciatives de la Biblioteca Universitària emmarcades dins del moviment Open Access, que se sumen a la ja existent Memòria Digital de Canàries, que es va iniciar l'any 2003 amb molt d'èxit. Tot i que el programari utilitzat per al desenvolupament d'ACCEDA és DSpace, la Biblioteca Universitària ha implementat serveis als usuaris i administradors, com per exemple, la possibilitat de dipositar documents sense haver d'utilitzar l'autoarxivament i la incorporació de l'eina BUStreaming desenvolupada per la pròpia Biblioteca.

The influence of individual, social and physical environment factors on physical activity in the adult population in Andalusia, Spain

A person’s physical and social environment is considered as an influencing factor in terms of rates of engagement in physical activity. This study analyses the influence of socio-demographic, physical and social environmental factors on physical activity reported in the adult population in Andalusia. This is a cross-sectional study using data collected in the Andalusia Health Survey in 1999 and 2003. In addition to the influence of the individual’s characteristics, if there are no green spaces in the neighbourhood it is less likely that men and women will take exercise (OR = 1.26; 95% CI = 1.13, 1.41). Likewise, a higher local illiteracy rate also has a negative influence on exercise habits in men (OR = 1.39; 95% CI = 1.21, 1.59) and in women (OR = 1.22; 95% CI = 1.07, 1.40). Physical activity is influenced by individuals’ characteristics as well as by their social and physical environment, the most disadvantaged groups are less likely to engage in physical activity

Optimization of treatment with interferon beta in multiple sclerosis. Usefulness of automatic system application criteria

Background. A software based tool has been developed (Optem) to allow automatize the recommendations of the Canadian Multiple Sclerosis Working Group for optimizing MS treatment in order to avoid subjective interpretation. METHODS: Treatment Optimization Recommendations (TORs) were applied to our database of patients treated with IFN beta1a IM. Patient data were assessed during year 1 for disease activity, and patients were assigned to 2 groups according to TOR: "change treatment" (CH) and "no change treatment" (NCH). These assessments were then compared to observed clinical outcomes for disease activity over the following years. RESULTS: We have data on 55 patients. The "change treatment" status was assigned to 22 patients, and "no change treatment" to 33 patients. The estimated sensitivity and specificity according to last visit status were 73.9% and 84.4%. During the following years, the Relapse Rate was always higher in the "change treatment" group than in the "no change treatment" group (5 y; CH: 0.7, NCH: 0.07; p < 0.001, 12 m - last visit; CH: 0.536, NCH: 0.34). We obtained the same results with the EDSS (4 y; CH: 3.53, NCH: 2.55, annual progression rate in 12 m - last visit; CH: 0.29, NCH: 0.13). CONCLUSION: Applying TOR at the first year of therapy allowed accurate prediction of continued disease activity in relapses and disability progression.

Lymphoid environment limits superantigen and antigen-induced T cell proliferation at high precursor frequency.

After superantigen challenge a significant proportion of superantigen-reactive T cells remain undivided. We provide evidence that the lymphoid environment limits T cell proliferation in the secondary lymphoid organs when the frequency of superantigen reactive T cells is unusually high. We monitored T cell proliferation and the percentage of undivided cells when the frequency of superantigen-reactive T cells was low (1%), intermediate (15%) or high (30-100%) by transferring fluorescently labeled cells into different recipients. When the frequency was low, practically all the reactive T cells entered cell cycle and proliferated maximally. At intermediate frequencies a large proportion of reactive T cells did not enter cell cycle and the whole population divided less. A further increase in reactive T cells did not alter the percentage of undivided cells but induced a further decrease in the number of cell divisions. Interestingly, the observations made with superantigens were confirmed with peptide antigen and TCR-transgenic mice. Moreover, in vivo and in vitro data suggest that dendritic cells are the most likely candidates in limiting T cell proliferation in the lymphoid environment. In conclusion, we show that the availability of APC in the lymphoid environment can quantitatively limit T cell priming.
