    164 p.Autism Spectrum Disorder (ASD) is a largely prevalent neurodevelopmental condition with a big social and economical impact affecting the entire life of families. There is an intense search for biomarkers that can be assessed as early as possible in order to initiate treatment and preparation of the family to deal with the challenges imposed by the condition. Brain imaging biomarkers have special interest. Specifically, functional connectivity data extracted from resting state functional magnetic resonance imaging (rs-fMRI) should allow to detect brain connectivity alterations. Machine learning pipelines encompass the estimation of the functional connectivity matrix from brain parcellations, feature extraction and building classification models for ASD prediction. The works reported in the literature are very heterogeneous from the computational and methodological point of view. In this Thesis we carry out a comprehensive computational exploration of the impact of the choices involved while building these machine learning pipelines

Machine learning pipelines encompass the estimation of the functional connectivity matrix from brain parcellations, feature extraction, and building classification models for ASD prediction. The works reported in the literature are very heterogeneous from the computational and methodological point of view. In this paper, we carry out a comprehensive computational exploration of the impact of the choices involved while building these machine learning pipelines. Specifically, we consider six brain parcellation definitions, five methods for functional connectivity matrix construction, six feature extraction/selection approaches, and nine classifier building algorithms. We report the prediction performance sensitivity to each of these choices, as well as the best results that are comparable with the state of the art.This work has been partially supported by theFEDER funds through MINECO project TIN2017-85827-P.

    A cultura da entronização e da eternização da elite política

    Get PDF
    Para além de outras contingências, as consequências práticas da entrada em vigor da lei da limitação dos mandatos1 revelaram uma tendência da elite política para o cultivo de estratégias de residência permanente nos lugares de representação. As atitudes sequentes dos políticos, colhidos pela legislação, em procurar, imediatamente, outros cargos com visibilidade e poder na administração pública ou em passar dos órgãos executivos para os órgãos deliberativos, denunciam, genericamente, uma cultura política estabelecida e uma predisposição propensa ao torneamento de regulamentos, verificando- -se, desse modo, uma fórmula similar de funcionamento das diversas organizações partidárias e um espírito pariforme na interpretação do fenómeno político pelos seus agentes.info:eu-repo/semantics/publishedVersio

    Este artículo analiza el panorama de la literatura narrativa infantil publicada en España y Portugal en la década de los años 80 y 90. Con el fin de la dictadura política en estos dos países, se abre un nuevo periodo literario en el que autores de este momento histórico escriben para un tipo de público, el infantil, que muestra curiosidad e interés por nuevas temáticas que contribuirán a su progresiva formación intelectual y lectora. Los autores, títulos y editoriales presentados en este trabajo son un fiel reflejo de la nueva literatura infantil del momento que se hace eco de estas necesidades pedagógicas.This essay analyzes narrative children’s literature published in Spain and Portugal in the late 80s and 90s. With the end of political dictatorship in these countries, it occurs a new literary period in which authors of this historic moment write to a sort of public, children, who shows curiosity and interest in new topics that will help his progressive intellectual and reading formation. The authors, titles and publishers presented in this study are a reflection of the new children's literature of that time, making echo of these educational needs.Cet article analyse le panorama de la littérature infantile pour les enfants, publiée en Espagne et en Portugal durant la décade des années 80 et 90.

    El presente Seminario de graduación tiene como propósito evaluar el Sistema Contable y la estructura de Control Interno de la empresa Estación de Servicios Gas Central, en el municipio de Matagalpa, departamento de Matagalpa durante el primer semestre del año 2015. El Sistema Contable es importante en las organizaciones para registrar las operaciones contables y procesarlas en informes financieros para la toma de decisiones. El Control Interno es el conjunto de políticas y normas que proporcionan información financiera confiable y el logro de los objetivos organizacionales. En el desarrollo del documento se describe el Sistema Contable y sus características, tipos de sistemas, marco normativo, libros contables y estados financieros. Además se detalla la estructura del Control Interno, sus objetivos, elementos del modelo COSO, tipos de controles, las debilidades del Control y contenido del Manual de Control Interno. Esta información es importante para Estación de Servicios Gas Central porque contiene las principales debilidades en el Sistema Contable y la estructura de Control Interno que implementan, así mismo, las alternativas de solución necesarias para corregirlas y garantizar el cumplimiento razonable de los objetivos. Para obtener la información, se aplicaron los instrumentos de la entrevista y el cuestionario al propietario y a la contadora de la entidad, concluyendo que se implementa un Sistema Contable Manual en base a los PCGA´s y que los funcionarios de la misma aplican normas de Control Interno poco formales las cuales no están contenidas en un Manual de Control Interno debidamente aprobado por el propietario

    A roadmap toward the automatic composition of systematic literature reviews

    Get PDF
    Objective.  This paper presents an overview of existing artificial intelligence tools to produce systematic literature reviews. Furthermore, we propose a general framework resulting from combining these techniques to highlight the challenges and possibilities currently existing in this research area. Design/Methodology/Approach. We undertook a scoping review on the systematic literature review steps to automate them via computational techniques. Results/Discussion. The process of creating a literature review is both creative and technical. The technical part of this process is liable to automation. Based on the literature, we chose to divide this technical part into four steps: searching, screening, extraction, and synthesis. For each one of these steps, we presented practical artificial intelligence techniques to carry them out. In addition, we presented the obstacles encountered in the application of each technique. Conclusion. We proposed a framework for automatically creating systematic literature reviews by combining and placing existing techniques in stages where they possess the greatest potential to be useful. Despite still lacking practical assessment in different areas of knowledge, this proposal indicates ways with the potential to reduce the time-consuming and repetitive work embedded in the systematic literature review process. Originality/Value. The paper presents the current possibilities for automating systematic literature reviews and how they can work together to reduce researchers’ operational workload

    A Preponderância dos Factores Exógenos na Rejeição do Plano Português de Descolonização para Timor-Leste,1974-1975

    Pouco tempo após as autoridades portuguesas terem aprovado o projecto dedescolonização para Timor-Leste, a Indonésia intensificou a sua campanha dedesinformação e destabilização da colónia portuguesa. Este comportamento porparte do regime de Suharto contou com a conivência e apoio do governo australiano e contribuiu decisivamente para por termo ao processo de descolonização doterritório, que culminou com a sua invasão em 7 de Dezembro de 1975. Apesar deas autoridades portuguesas, quer em Lisboa, quer em Timor, se terem esforçado nosentido de obter um processo prolongado de descolonização para o território, talnão se veio a observar atendendo a que Portugal foi considerado e tido como umactor secundário na região.Todavia, se recuarmos aos períodos antes da elaboração do plano de descolonizaçãoe do 25 de Abril de 1974, já era notório e constante na política ocidental a aceitaçãodo princípio orientador de que Timor-Leste deveria integrar a Indonésia.Shortly after the approval by the Portuguese authorities of the plan for the decolonization of East Timor, Indonesia intensified its disinformation and destabilization campaign of the former Portuguese colony. This behaviour by Suharto's regime counted with the connivance of the Australian government, thus contributing decisively to the invasion of the former Portuguese colony on 7 December 1975. Despite the efforts done by the Portuguese authorities, both in Lisbon and Díli, to ensure a drawn out act of self-determination for East Timor, this did not take place due to the fact that Portugal was considered a second rate power in the region. However, if we analyse the draft plan and the pre-Portuguese revolution periods, it was already noticeable and a permanent feature in Western policy the acceptance of East Timor's incorporation into Indonesia
