Our extended senses, tools, technologies, through the ages, have been closed systems incapable of interplay or collective awareness. Now, in the electric age, the very instantaneous nature of co-existence among our technological instruments has created a crisis quite new in human history. Our extended faculties and senses now constitute a single field of experience which demands that they become collectively conscious. Our technologies, like our private senses, now demand an interplay and ratio that makes rational co-existence possible. As long as our technologies were as slow as the wheel or the alphabet or money, the fact that they were separate, closed systems was socially and psychically supportable. This is not true now when sight and sound and movement are simultaneous and global in extent. (McLuhan 1962, p.5, emphasis in original)Over forty years later, the seamless interplay that McLuhan demanded between our technologies is still barely visible. McLuhan’s predictions of the spread, and increased importance, of electronic media have of course been borne out, and the worlds of business, science and knowledge storage and transfer have been revolutionised. Yet the integration of electronic systems as open systems remains in its infancy.Advanced Knowledge Technologies (AKT) aims to address this problem, to create a view of knowledge and its management across its lifecycle, to research and create the services and technologies that such unification will require. Half way through its sixyear span, the results are beginning to come through, and this paper will explore some of the services, technologies and methodologies that have been developed. We hope to give a sense in this paper of the potential for the next three years, to discuss the insights and lessons learnt in the first phase of the project, to articulate the challenges and issues that remain.The WWW provided the original context that made the AKT approach to knowledge management (KM) possible. AKT was initially proposed in 1999, it brought together an interdisciplinary consortium with the technological breadth and complementarity to create the conditions for a unified approach to knowledge across its lifecycle. The combination of this expertise, and the time and space afforded the consortium by the IRC structure, suggested the opportunity for a concerted effort to develop an approach to advanced knowledge technologies, based on the WWW as a basic infrastructure.The technological context of AKT altered for the better in the short period between the development of the proposal and the beginning of the project itself with the development of the semantic web (SW), which foresaw much more intelligent manipulation and querying of knowledge. The opportunities that the SW provided for e.g., more intelligent retrieval, put AKT in the centre of information technology innovation and knowledge management services; the AKT skill set would clearly be central for the exploitation of those opportunities.The SW, as an extension of the WWW, provides an interesting set of constraints to the knowledge management services AKT tries to provide. As a medium for the semantically-informed coordination of information, it has suggested a number of ways in which the objectives of AKT can be achieved, most obviously through the provision of knowledge management services delivered over the web as opposed to the creation and provision of technologies to manage knowledge.AKT is working on the assumption that many web services will be developed and provided for users. The KM problem in the near future will be one of deciding which services are needed and of coordinating them. Many of these services will be largely or entirely legacies of the WWW, and so the capabilities of the services will vary. As well as providing useful KM services in their own right, AKT will be aiming to exploit this opportunity, by reasoning over services, brokering between them, and providing essential meta-services for SW knowledge service management.Ontologies will be a crucial tool for the SW. The AKT consortium brings a lot of expertise on ontologies together, and ontologies were always going to be a key part of the strategy. All kinds of knowledge sharing and transfer activities will be mediated by ontologies, and ontology management will be an important enabling task. Different applications will need to cope with inconsistent ontologies, or with the problems that will follow the automatic creation of ontologies (e.g. merging of pre-existing ontologies to create a third). Ontology mapping, and the elimination of conflicts of reference, will be important tasks. All of these issues are discussed along with our proposed technologies.Similarly, specifications of tasks will be used for the deployment of knowledge services over the SW, but in general it cannot be expected that in the medium term there will be standards for task (or service) specifications. The brokering metaservices that are envisaged will have to deal with this heterogeneity.The emerging picture of the SW is one of great opportunity but it will not be a wellordered, certain or consistent environment. It will comprise many repositories of legacy data, outdated and inconsistent stores, and requirements for common understandings across divergent formalisms. There is clearly a role for standards to play to bring much of this context together; AKT is playing a significant role in these efforts. But standards take time to emerge, they take political power to enforce, and they have been known to stifle innovation (in the short term). AKT is keen to understand the balance between principled inference and statistical processing of web content. Logical inference on the Web is tough. Complex queries using traditional AI inference methods bring most distributed computer systems to their knees. Do we set up semantically well-behaved areas of the Web? Is any part of the Web in which semantic hygiene prevails interesting enough to reason in? These and many other questions need to be addressed if we are to provide effective knowledge technologies for our content on the web

    Inmersos de lleno en la Sociedad del conocimiento, la incorporación de las Tecnologías de la Información y la Comunicación en los procesos de enseñanza y aprendizaje suponen un gran reto a alcanzar por parte tanto de instituciones educativas, como de un profesorado todavía poco formado y menos consciente de los cambios metodológicos a los que se enfrenta.En el marco de la formación del profesorado,la formación a lo largo de la vida se establece como prioridad en los programas educativos y de formación de la agenda europea (2007-2013) y a nuestro entender, ésta puede ser claramente ejemplificada por la creación de comunidades virtuales de aprendizaje en las que individuos con objetivos similares se unen para alcanzar retos en común. El uso de herramientas tecnológicas y de modalidades de formación basadas en entornos virtuales ayudan a la comunidad a generar e intercambiar conocimiento en un entorno en el que se participa de forma colaborativa, se comparten experiencias y se solucionan problemas, produciendo procesos de formación y aprendizaje continuos y en constante evolución.Tomando estas y otras reflexiones como punto de partida se originó la tesis doctoral que presentamos. Así pues, nos propusimos, en primer lugar, realizar un análisis de la situación actual de dicho profesorado en el uso de las tecnologías de la información y la comunicación. El primer gran bloque de esta tesis -o marco teórico y referencial- lo constituyen apartados tales como los grandes cambios metodológicos surgidos a raíz de la incorporación de las TIC y su impacto en la enseñanza y aprendizaje de la lengua inglesa. Seguidamente se realiza un exhaustivo y detallado análisis de los órganos que ofrecen formación al profesorado y a la oferta formativa en TIC dirigida específicamente al colectivo mencionado. Posteriormente se lleva a cabo una compilación de herramientas, recursos y actividades electrónicas dirigidas específicamente al profesorado de inglés teniendo muy en cuenta el ámbito pedagógico y su implantación en el aula, proponiendo pautas didácticas de fácil integración.El segundo gran bloque de la tesis lo constituye una investigación llevada a cabo durante tres años para obtener datos fehacientes respecto del conocimiento en TIC que posee dicho profesorado, la detección de sus demandas formativas reales, la situación actual de este colectivo en relación al acceso e infraestructuras tecnológicas y posibles barreras tanto metodológicas como actitudinales. Así pues se desarrolló una investigación tomando como muestra profesores tanto de educación primaria como de secundaria de todo Catalunya. Dicha investigación fue llevada a a cabo entre los participantes de ocho cursos de formación TIC para profesorado de inglés y para ello se utilizó la modalidad formativa semi-presencial. Para dar soporte a la formación a distancia se utilizaron dos plataformas diferentes: BSCW y Moodle que fomentaron la comunicación y la colaboración entre los participantes hasta límites insospechados.Los resultados obtenidos permitieron observar una realidad muy alejada de los parámetros que deberían ser considerados normales por lo que respecta al grado de formación TIC que tienen el profesorado de inglés. Por otra parte, el feedback recibido tras la realización de los diferentes cursos de formación también nos permitió realizar una propuesta de Plan de Acción formativo con el principal objetivo de capacitar al profesorado de inglés en el uso de las TIC. Así pues, se ofrece una propuesta formativa con los diferentes módulos y contenidos que, a nuestro entender, debería conocer y gestionar dicho profesorado. Finalmente, una de las revelaciones de todo el proceso fue la gestación y consolidación de una comunidad virtual de aprendizaje formada por los profesores participantes en el proceso de formación.Deeply immersed in the Society of knowledge, the integration of ICT in teaching and learning processes suppose a great challenge to be achieved both by competent institutions and by a collective of teachers, which is still far from being well-trained and not conscious of the methodological trenes and changes to which they are confronted.Within the framework of teacher training, life-long training is established as a priority in the European agenda (2007-2013) and, according to our opinión this can be exempolified by the creation of virtual learning communities in which individuals with similar objectives unite in order to achieve common goals. The use of technological tools and training modalities help the community to generate and exchange knowledge in an environment in which oparticipation is done collaborately, experiences are shared and problems are solved, producing, thus, continuous processes of learning and training, which are in constant evolution.Taking these and other reflexions as departing point this thesis was originated. We carried in the first place a detailed analysis of the present situation of English as a foreign language teachers in the use of ICT. This first great section of this thesis orreferential and theoretical basis- is conformed by chapters which deal with the great methodological changes emerged out of the integartion of ICT and their impact in the teaching and learning of foreign languages. Followingly, there is an exhaustive analysis of the different organizations which offer teacher training in ICT , especially regarding the collective mentioned. Secondly there is a compilation of tools, resources and e.activities especifically addressed to the English as a foreign language teachers, taking into account the pedagogical field as well as its integration into the classrooms.The second main section of this thesis is conformed by an investigation which was carried out during three years in order to obtain relevant data regarding the knowledge of ICT that teachers have, the detection of their training needs and the real situation of this collective regarding their access to technology and the barriers that prevent them form using ICT.Tus, we Developer an investigation which took as sample teachers belonging to both Primary and Secondary Education from the whole of the catalan territory. The research was carried out with participants of eight courses of teacher training in ICT and used the blended modality. In order to support the virtual teaching we used two different platforms: BSCW and Moodle, which encouraged communication among participants and enhanced collaboration as well.The obtained results allowed us to observe that there are many challenges to be overcome. Otherwise, the feedback obtained after the courses were delivered allowed us to account for a Training Action Plan whose main aim is that of providing training and capacitation to teachers of English as foreign language teachers

    Semantic discovery and reuse of business process patterns

    Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

    “Articulating the New Normal(s): Mental Disability, Medical Discourse, and Rhetorical Action” studies the writing of people diagnosed with autism and post- traumatic stress disorder within online discussion boards related to mental health and outlines their unique rhetorical strategies for interacting with biomedical ideologies of psychiatry and activist discourses. The opening chapter situates this dissertation in relation to previous scholarship in Rhetoric, Disability Studies, and other fields. I also provide a summary of the set of mixed methods I use to gather and analyze my data, including rhetorical analysis, corpus analysis, and qualitative interviews. In Chapter 2, “Medical Terminology and Discourse Features of Online Discussions of Mental Health,” I explore the ways in which medical discourse appears in discussions of mental disability through medical terms that writers and speakers use when discussing a diagnosis. Using methods borrowed from linguistics, I demonstrate that the writers in my study make different linguistic choices than the general public, and that the most prominent differences are related to the social construction of mental health and medicine. In Chapter 3, “Inhabiting Biological Primacy with Chiasmic Rhetoric in Mental Health Forums,” I describe and analyze a variety of common topics in online conversations that connect mental health and expert knowledge of the brain. I argue that this connection of mental experience and brain science constitutes a chiasmic rhetoric. The writers foregrounded in this chapter acknowledge and accept much of the claims of medicine and neuroscience regarding the brain but, uniquely, work to divide that knowledge from the path of normativity and optimization. Chapter 4, “Classified Conversations: Psychiatry and Technical Communication in Online Spaces,” examines the practices of participants in online mental health discussion forums conversations as they interpret technical documents. I detail four salient forms of the manipulation of medical discourse in online communities. At the close of this chapter, I explain how these insights can inform academic study of writing in mental health contexts and transform the content and application of medical and technical texts. In Chapter 5, “Re-Forming Mental Health: Rhetorical Innovation and the Language of Advocacy,” I summarize and synthesize the core arguments of earlier chapters, with an extended caveat regarding the ethical dilemmas of this study. Finally, I offer a set of practical recommendations for different communities with which my research has been conversant, the fields of Rhetoric and Rhetoric of Health and Medicine, Disability Studies, and activism related to mental disabilities
