Contraste e alteridade na viagem contemporânea

No mundo contemporâneo globalizado, definido pela sua qualidade essencialmente fluida e instável, o carácter distintivo da viagem parece dissolver-se face à contracção do planeta, à economia das ―trocas simbólicas‖ e a um alegado processo de diluição das diferenças e de homogeneização cultural. Com efeito, a mediatização da sociedade e a proliferação icónica contemporâneas produzem um aparente estado de saturação da geografia real e de multiplicação de lugares enquanto representações e imagens, permitindo pôr em causa a própria necessidade e urgência de deslocação, bem como admitir a abolição do ―estatuto de privilégio‖ de certos lugares e a derradeira quebra no conceito aurático das férias e das viagens, tradicionalmente assente em antinomias cruciais entre o quotidiano/familiar e o diferente/extraordinário. O presente artigo propõe-se abordar o paradigma da mobilidade contemporânea, nomeadamente no que diz respeito à traumática aniquilação do espaço e do tempo e ao seu impacto fortemente disruptivo sobre a dimensão ontológica de uma prática cultural cujo poder aurático se encontra tradicionalmente relacionado com a conquista de distâncias, a percepção de diferenças e a experiência de alteridade. O artigo pretende, por outro lado, refutar a declaração pós-moderna de que a familiarização com o outro conduz a uma diminuição do potencial de choque cultural no turismo contemporâneo, discutindo a relevância e a prevalência da busca de contraste e formas de vivência de alteridade no complexo novelo de motivações da viagem turística contemporânea.

O feminino na obra de Uanhenga Xitu

Interessa-nos para este artigo perscrutar as representações da vida social em narrativas do escritor angolano Uanhenga Xitu, mormente no que diz respeito à personagem feminina e ao papel da mulher nas sociedades tradicionais angolanas. Nas narrativas cujas ações se passam no interior de Angola, as representações sociais da mulher revelam um modus vivendi diferenciado daquele experimentado por mulheres que migram para a capital, Luanda, espaço em que a noção de vida comunitária, tão significativa nas sociedades tradicionais, perde seu significado. Os trabalhos lá executados, por exemplo, serão em favor do colono, como os dos empregados domésticos, e não para a coletividade. Já nos espaços interiores, mais distantes da mão pesada do colonizador, as representações da vida social dos angolanos são mais expressivas e essa diferenciação revela que a migração do campo para a cidade, no caso de um país dominado pela colonização, metaforiza o abandono de um tipo de (con)vivência social em favor de outro. Como a política colonial portuguesa foi assimilacionista, essa migração será sinônimo de busca de adesão ao modus vivendi do outro, muitas vezes para sofrer menos os efeitos da dominação. Para essa discussão, não é por livre escolha que se tratará das personagens femininas na obra de Xitu, posto que as mulheres em seus textos ganham vez e voz para a expressão do proprium angolano, como se o autor as quisesse homenagear em sinal do reconhecimento de sua importância na construção e preservação da memória, que é capaz de criar laços identitários entre as milenares gerações passadas e as futuras, como esboçaremos (Esta reflexão teve origem no estudo desenvolvido no doutoramento, intitulado Entre dois contares: o espaço da tradição na escrita de Uanhenga Xitu, defendida em 1996 na FFLCH-USP, e orientada pela Dra. Maria Aparecida Santilli, falecida em março de 2008).

Tratamiento y presencia de las mujeres em la prensa

Este artículo presenta los resultados de un análisis de contenido sobre la representación de la mujer en la prensa española que forma parte de una investigación más amplia que abarca el periodo de 1974-2000. Nuestra investigación supone una importante contribución a otras investigaciones ya que analiza de forma comparativa, sistemática y longitudinal las representaciones sociales y políticas enfocadas en la prensa. Examinamos como en los medios de comunicación los periodistas utilizan frecuentemente distintas referencias para los diferentes tipos de actores a partir de recursos estilísticos que ayudan a enfatizar sus argumentos. En la mayoría de los casos, estos pasan desapercibidos pero en ocasiones se convierten en generalizaciones que parten de ideas preconcebidas y prejuicios. Nuestros resultados demuestran que los actores a los que los medios de comunicación dedican menos espacio son también los que reciben un peor tratamiento. Específicamente, las mujeres reciben una menor atención como colectivo en los medios de comunicación analizados. Además, aparecen como personajes pasivos, no son enfocadas como representantes públicas y son relegadas a la vida privada. Principalmente, las mujeres son enfocadas realizando actividades deportivas, culturales o de entretenimiento o cuando son víctimas, mientras que sólo una minoría de ellas merecen atención efectuando acciones políticas. Después de exponer este diagnóstico, realizaremos propuestas de estilo, lenguaje y producción de noticias para fomentar que los periódicos muestren de forma positiva una sociedad con igualdad de oportunidades.

Fractional dynamics and MDS visualization of earthquake phenomena

This paper analyses earthquake data in the perspective of dynamical systems and fractional calculus (FC). This new standpoint uses Multidimensional Scaling (MDS) as a powerful clustering and visualization tool. FC extends the concepts of integrals and derivatives to non-integer and complex orders. MDS is a technique that produces spatial or geometric representations of complex objects, such that those objects that are perceived to be similar in some sense are placed on the MDS maps forming clusters. In this study, over three million seismic occurrences, covering the period from January 1, 1904 up to March 14, 2012 are analysed. The events are characterized by their magnitude and spatiotemporal distributions and are divided into fifty groups, according to the Flinn–Engdahl (F–E) seismic regions of Earth. Several correlation indices are proposed to quantify the similarities among regions. MDS maps are proven as an intuitive and useful visual representation of the complex relationships that are present among seismic events, which may not be perceived on traditional geographic maps. Therefore, MDS constitutes a valid alternative to classic visualization tools for understanding the global behaviour of earthquakes.

Simulation relations, interface complexity, and resource optimality for real-time hierachical systems

Compositional schedulability analysis of hierarchical realtime systems is a well-studied problem. Various techniques have been developed to abstract resource requirements of components in such systems, and schedulability has been addressed using these abstract representations (also called component interfaces). These approaches for compositional analysis incur resource overheads when they abstract components into interfaces. In this talk, we define notions of resource schedulability and optimality for component interfaces, and compare various approaches.

Extended immersive learning environment: a hybrid remote/virtual laboratory

This paper presents a collaborative virtual learning environment, which includes technologies such as 3D virtual representations, learning and content management systems, remote experiments, and collaborative learning spaces, among others. It intends to facilitate the construction, management and sharing of knowledge among teachers and students, in a global perspective. The environment proposes the use of 3D social representations for accessing learning materials in a dynamic and interactive form, which is regarded to be closer to the physical reality experienced by teachers and students in a learning context. A first implementation of the proposed extended immersive learning environment, in the area of solid mechanics, is also described, including the access to theoretical contents and a remote experiment to determine the elastic modulus of a given object.These instructions give you basic guidelines for preparing camera-ready papers for conference proceedings.

Terminology and knowledge engineering conference. New frontiers in the constructive symbiosis of terminology and knowledge engineering

To meet the increasing demands of the complex inter-organizational processes and the demand for continuous innovation and internationalization, it is evident that new forms of organisation are being adopted, fostering more intensive collaboration processes and sharing of resources, in what can be called collaborative networks (Camarinha-Matos, 2006:03). Information and knowledge are crucial resources in collaborative networks, being their management fundamental processes to optimize. Knowledge organisation and collaboration systems are thus important instruments for the success of collaborative networks of organisations having been researched in the last decade in the areas of computer science, information science, management sciences, terminology and linguistics. Nevertheless, research in this area didn’t give much attention to multilingual contexts of collaboration, which pose specific and challenging problems. It is then clear that access to and representation of knowledge will happen more and more on a multilingual setting which implies the overcoming of difficulties inherent to the presence of multiple languages, through the use of processes like localization of ontologies. Although localization, like other processes that involve multilingualism, is a rather well-developed practice and its methodologies and tools fruitfully employed by the language industry in the development and adaptation of multilingual content, it has not yet been sufficiently explored as an element of support to the development of knowledge representations - in particular ontologies - expressed in more than one language. Multilingual knowledge representation is then an open research area calling for cross-contributions from knowledge engineering, terminology, ontology engineering, cognitive sciences, computational linguistics, natural language processing, and management sciences. This workshop joined researchers interested in multilingual knowledge representation, in a multidisciplinary environment to debate the possibilities of cross-fertilization between knowledge engineering, terminology, ontology engineering, cognitive sciences, computational linguistics, natural language processing, and management sciences applied to contexts where multilingualism continuously creates new and demanding challenges to current knowledge representation methods and techniques. In this workshop six papers dealing with different approaches to multilingual knowledge representation are presented, most of them describing tools, approaches and results obtained in the development of ongoing projects. In the first case, Andrés Domínguez Burgos, Koen Kerremansa and Rita Temmerman present a software module that is part of a workbench for terminological and ontological mining, Termontospider, a wiki crawler that aims at optimally traverse Wikipedia in search of domainspecific texts for extracting terminological and ontological information. The crawler is part of a tool suite for automatically developing multilingual termontological databases, i.e. ontologicallyunderpinned multilingual terminological databases. In this paper the authors describe the basic principles behind the crawler and summarized the research setting in which the tool is currently tested. In the second paper, Fumiko Kano presents a work comparing four feature-based similarity measures derived from cognitive sciences. The purpose of the comparative analysis presented by the author is to verify the potentially most effective model that can be applied for mapping independent ontologies in a culturally influenced domain. For that, datasets based on standardized pre-defined feature dimensions and values, which are obtainable from the UNESCO Institute for Statistics (UIS) have been used for the comparative analysis of the similarity measures. The purpose of the comparison is to verify the similarity measures based on the objectively developed datasets. According to the author the results demonstrate that the Bayesian Model of Generalization provides for the most effective cognitive model for identifying the most similar corresponding concepts existing for a targeted socio-cultural community. In another presentation, Thierry Declerck, Hans-Ulrich Krieger and Dagmar Gromann present an ongoing work and propose an approach to automatic extraction of information from multilingual financial Web resources, to provide candidate terms for building ontology elements or instances of ontology concepts. The authors present a complementary approach to the direct localization/translation of ontology labels, by acquiring terminologies through the access and harvesting of multilingual Web presences of structured information providers in the field of finance, leading to both the detection of candidate terms in various multilingual sources in the financial domain that can be used not only as labels of ontology classes and properties but also for the possible generation of (multilingual) domain ontologies themselves. In the next paper, Manuel Silva, António Lucas Soares and Rute Costa claim that despite the availability of tools, resources and techniques aimed at the construction of ontological artifacts, developing a shared conceptualization of a given reality still raises questions about the principles and methods that support the initial phases of conceptualization. These questions become, according to the authors, more complex when the conceptualization occurs in a multilingual setting. To tackle these issues the authors present a collaborative platform – conceptME - where terminological and knowledge representation processes support domain experts throughout a conceptualization framework, allowing the inclusion of multilingual data as a way to promote knowledge sharing and enhance conceptualization and support a multilingual ontology specification. In another presentation Frieda Steurs and Hendrik J. Kockaert present us TermWise, a large project dealing with legal terminology and phraseology for the Belgian public services, i.e. the translation office of the ministry of justice, a project which aims at developing an advanced tool including expert knowledge in the algorithms that extract specialized language from textual data (legal documents) and whose outcome is a knowledge database including Dutch/French equivalents for legal concepts, enriched with the phraseology related to the terms under discussion. Finally, Deborah Grbac, Luca Losito, Andrea Sada and Paolo Sirito report on the preliminary results of a pilot project currently ongoing at UCSC Central Library, where they propose to adapt to subject librarians, employed in large and multilingual Academic Institutions, the model used by translators working within European Union Institutions. The authors are using User Experience (UX) Analysis in order to provide subject librarians with a visual support, by means of “ontology tables” depicting conceptual linking and connections of words with concepts presented according to their semantic and linguistic meaning. The organizers hope that the selection of papers presented here will be of interest to a broad audience, and will be a starting point for further discussion and cooperation.

Multidimensional scaling visualization of earthquake phenomena

Earthquakes are associated with negative events, such as large number of casualties, destruction of buildings and infrastructures, or emergence of tsunamis. In this paper, we apply the Multidimensional Scaling (MDS) analysis to earthquake data. MDS is a set of techniques that produce spatial or geometric representations of complex objects, such that, objects perceived to be similar/distinct in some sense are placed nearby/distant on the MDS maps. The interpretation of the charts is based on the resulting clusters since MDS produces a different locus for each similarity measure. In this study, over three million seismic occurrences, covering the period from January 1, 1904 up to March 14, 2012 are analyzed. The events, characterized by their magnitude and spatiotemporal distributions, are divided into groups, either according to the Flinn–Engdahl seismic regions of Earth or using a rectangular grid based in latitude and longitude coordinates. Space-time and Space-frequency correlation indices are proposed to quantify the similarities among events. MDS has the advantage of avoiding sensitivity to the non-uniform spatial distribution of seismic data, resulting from poorly instrumented areas, and is well suited for accessing dynamics of complex systems. MDS maps are proven as an intuitive and useful visual representation of the complex relationships that are present among seismic events, which may not be perceived on traditional geographic maps. Therefore, MDS constitutes a valid alternative to classic visualization tools, for understanding the global behavior of earthquakes.

Prova de Consciência Morfológica (PCM): contributos para a sua validação

A relação entre consciência fonológica e consciência morfológica e a contribuição independente de cada uma para a aprendizagem da leitura não reúnem ainda consenso na literatura. Alguns autores argumentam que a consciência morfológica não contribui de forma independente da consciência fonológica para a aprendizagem da leitura. No entanto, outros encontraram dados que indicam que a consciência morfológica tem um papel específi co na progressão da aprendizagem da leitura. Todavia, para além da variedade de tarefas usadas não permitir a comparação de resultados, a ausência de estudos prévios sobre a validade e a fi delidade das mesmas conduz a resultados cuja confi abilidade pode ser posta em causa. Este estudo tem como objetivo apresentar uma análise das qualidades psicométricas da PCM - Prova de Consciência Morfológica. A amostra é constituída por 243 crianças do 2.º (n = 79), 3.º (n = 83) e 4.º (n = 81) anos frequentando escolas públicas, urbanas, do distrito do Porto (norte de Portugal). Os resultados revelaram que a PCM possui uma elevada consistência interna (α = .95). Na análise em componentes principais, foi extraído um único fator, com valor próprio igual a 10.88, que explica 54.42% da variância total dos resultados. Os itens são todos saturados no fator, variando as saturações fatoriais entre um mínimo de .42 e o máximo de .91

Auditory event-related potentials in children with benign epilepsy with centro-temporal spikes

Benign focal epilepsy in childhood with centro-temporal spikes (BECTS) is one of the most common forms of idiopathic epilepsy, with onset from age 3 to 14 years. Although the prognosis for children with BECTS is excellent, some studies have revealed neuropsychological deficits in many domains, including language. Auditory event-related potentials (AERPs) reflect activation of different neuronal populations and are suggested to contribute to the evaluation of auditory discrimination (N1), attention allocation and phonological categorization (N2), and echoic memory (mismatch negativity – MMN). The scarce existing literature about this theme motivated the present study, which aims to investigate and document the existing AERP changes in a group of children with BECTS. AERPs were recorded, during the day, to pure and vocal tones and in a conventional auditory oddball paradigm in five children with BECTS (aged 8–12; mean = 10 years; male = 5) and in six gender and age-matched controls. Results revealed high amplitude of AERPs for the group of children with BECTS with a slight latency delay more pronounced in fronto-central electrodes. Children with BECTS may have abnormal central auditory processing, reflected by electrophysiological measures such as AERPs. In advance, AERPs seem a good tool to detect and reliably reveal cortical excitability in children with typical BECTS.

The development of the N1 and N2 components in auditory oddball paradigms: a systematic review with narrative analysis and suggested normative values

Auditory event-related potentials (AERPs) are widely used in diverse fields of today’s neuroscience, concerning auditory processing, speech perception, language acquisition, neurodevelopment, attention and cognition in normal aging, gender, developmental, neurologic and psychiatric disorders. However, its transposition to clinical practice has remained minimal. Mainly due to scarce literature on normative data across age, wide spectrumof results, variety of auditory stimuli used and to different neuropsychological meanings of AERPs components between authors. One of the most prominent AERP components studied in last decades was N1, which reflects auditory detection and discrimination. Subsequently, N2 indicates attention allocation and phonological analysis. The simultaneous analysis of N1 and N2 elicited by feasible novelty experimental paradigms, such as auditory oddball, seems an objective method to assess central auditory processing. The aim of this systematic review was to bring forward normative values for auditory oddball N1 and N2 components across age. EBSCO, PubMed, Web of Knowledge and Google Scholarwere systematically searched for studies that elicited N1 and/or N2 by auditory oddball paradigm. A total of 2,764 papers were initially identified in the database, of which 19 resulted from hand search and additional references, between 1988 and 2013, last 25 years. A final total of 68 studiesmet the eligibility criteria with a total of 2,406 participants from control groups for N1 (age range 6.6–85 years; mean 34.42) and 1,507 for N2 (age range 9–85 years; mean 36.13). Polynomial regression analysis revealed thatN1latency decreases with aging at Fz and Cz,N1 amplitude at Cz decreases from childhood to adolescence and stabilizes after 30–40 years and at Fz the decrement finishes by 60 years and highly increases after this age. Regarding N2, latency did not covary with age but amplitude showed a significant decrement for both Cz and Fz. Results suggested reliable normative values for Cz and Fz electrode locations; however, changes in brain development and components topography over age should be considered in clinical practice.

An ontology roadmap for crowdsourcing innovation intermediaries

Ontologies have proliferated in the last years, essentially justified by the need of achieving a consensus in the multiple representations of reality inside computers, and therefore the accomplishment of interoperability between machines and systems. Ontologies provide an explicit conceptualization that describes the semantics of the data. Crowdsourcing innovation intermediaries are organizations that mediate the communication and relationship between companies that aspire to solve some problem or to take advantage of any business opportunity with a crowd that is prone to give ideas based on their knowledge, experience and wisdom, taking advantage of web 2.0 tools. Various ontologies have emerged, but at the best of our knowledge, there isn’t any ontology that represents the entire process of intermediation of crowdsourcing innovation. In this paper we present an ontology roadmap for developing crowdsourcing innovation ontology of the intermediation process. Over the years, several authors have proposed some distinct methodologies, by different proposals of combining practices, activities, languages, according to the project they were involved in. We start making a literature review on ontology building, and analyse and compare ontologies that propose the development from scratch with the ones that propose reusing other ontologies. We also review enterprise and innovation ontologies known in literature. Finally, are presented the criteria for selecting the methodology and the roadmap for building crowdsourcing innovation intermediary ontology.

Módulo de realidade aumentada para uma aplicação LBS

As aplicações móveis de serviços baseados na localização, denominados LBS (Location-based services), disponibilizam serviços ao utilizador baseadas na sua localização geográfica. Este tipo de serviços começou a surgir ainda na década de 90 e, à medida que o número de dispositivos móveis cresceu de forma exponencial, a sua oferta disparou consideravelmente. Existem várias áreas com aplicabilidade prática, mas o foco desta tese é a pesquisa e localização de pontos de interesse (POI’s). Através dos sensores que os dispositivos móveis atualmente disponibilizam, torna-se possível localizar a posição do utilizador e apresentar-lhe os pontos de interesse que estão situados em seu redor. No entanto essa informação isolada revela-se por vezes insuficiente, uma vez que esses pontos de interesse são à partida desconhecidos para o utilizador. Através do serviço coolplaces, um projeto que pretende dedicar-se à pesquisa e partilha de POI’s, podemos criar a nossa rede de amigos e de locais, beneficiando assim da respetiva informação de contexto de um determinado POI. As inovações tecnológicas permitiram também o aparecimento de aplicações de Realidade Aumentada nos dispositivos móveis, isto é, aplicações capazes de sobrepor imagens virtuais a visualizações do mundo real. Considerando a visualização de POI’s num dado ambiente, se encararmos a Realidade Aumentada como um potenciador da interação do utilizador com o mundo real, rapidamente identificamos as potencialidades da junção destes conceitos numa só aplicação. Sendo assim, o trabalho desenvolvido nesta tese pretende constituir um estudo sobre a implementação e desenvolvimento de um módulo de Realidade Aumentada para a aplicação móvel do serviço coolplaces, fazendo uso da tecnologia disponível no mercado de forma a proporcionar uma experiência inovadora e acrescentar valor à referida aplicação.

As representações dos professores acerca da participação de alunos com necessidades educativas especiais em diversas atividades escolares

Os paradigmas concernentes à educação e ao atendimento de crianças com necessidades educativas especiais têm evoluído ao longo do tempo. De facto, se no paradigma da segregação o foco de incapacidade se situava no indivíduo, com o paradigma da inclusão o foco desloca-se para o ambiente, na medida em que este se deve organizar e preparar para dar resposta aos indivíduos com incapacidade. Por conseguinte, o meio deve assumir-se como facilitador à participação de todas as crianças. Tal fundamento comporta desafios para os professores e educadores, aos quais compete identificar as pressões de exclusão que inibem a participação plena de todos os alunos em todas as atividades inerentes ao meio escolar e acionar os suportes necessários para que tal não suceda. Com a realização deste estudo pretendemos conhecer de modo mais aprofundado as representações dos professores acerca da participação de alunos com diferentes tipos de incapacidade em variadas atividades e contextos escolares, identificando barreiras e facilitadores à sua participação e analisando os possíveis contributos pessoais dos professores para incrementar o nível de participação dos alunos com incapacidade em atividades inerentes ao meio escolar. O estudo operacionalizou-se através da aplicação de um inquérito por questionário, destinado a professores de todos os níveis de ensino e grupos de recrutamento. Através da aplicação deste instrumento, procurámos obter informações sobre os inquiridos, as representações dos professores acerca da participação de alunos com diferentes tipos de incapacidade em diversas atividades escolares, e, por fim, possíveis contributos para incrementar o nível de participação desses mesmos alunos. Os resultados sugerem que o tipo de incapacidade apresentado pelo aluno influencia as expetativas de participação de educadores e professores do ensino regular e da educação especial. Contudo, não confirmámos a existência de diferenças estatisticamente significativas entre os dois grupos de professores. No que concerne a possíveis contributos para incrementar a participação de alunos com incapacidade em diversas atividades escolares, identificámos a necessidade de se fomentar e desenvolver uma cultura de inclusão na escola.
