    RESUMO: O projeto OffshorePlan - Planeamento da instalação de energias renováveis offshore em Portugal – financiado pelo programa POSEUR (Programa Operacional Sustentabilidade e Eficiência no Uso de Recursos) do Portugal 2020 – surgiu na sequência da identificação de um conjunto de constrangimentos associados à implementação e disseminação das tecnologias de aproveitamento de energia para a produção de eletricidade em ambiente marinho. As energias renováveis de exploração marinha apresentam um grande potencial de exploração em Portugal, por um lado devido à situação geográfica do país, com a sua área extensa de costa e uma das maiores zonas económicas exclusivas (ZEE) – e por outro, pelos indicadores de existência de elevado recurso energético, cujo estudo tem vindo a ser efetuado nos últimos anos. Não obstante esses estudos persistem várias barreiras a ultrapassar para a disseminação das tecnologias de energias renováveis com maior aplicabilidade em Portugal – eólica offshore e ondas – as quais se prendem, essencialmente, com: i) mapeamento do recurso energético com precisão e sua validação experimental; ii) escassez de serviços e meios para ações de instalação e manutenção destes sistemas; iii) capacidade de receção da rede elétrica; e iv) impacto socioeconómico, entre outras.info:eu-repo/semantics/publishedVersio

    The happiness of people with mental illness: an integrative literature review

    CONTEXTO: A forma como cada pessoa vive e sente satisfação com a sua experiência de vida, tem naturalmente uma dimensão subjetiva mas reveladora de aspetos intrínsecos da dimensão humana. A felicidade pode ser um conceito agregador dessas dimensões embora de difícil definição para pessoas com ou sem doença mental. OBJETIVO: Identificar a perceção de felicidade em pessoas com doença mental, os fatores que contribuem para aumentar ou menorizar essa perceção. MÉTODOS:Revisão Integrativa da Literatura. Pesquisa em bases de dados internacionais, realizada em agosto de 2016. Foi aplicado um conjunto de descritores e critérios de inclusão. Obteve-se uma amostra final de 7 estudos, publicados entre 2006-2014. RESULTADOS:Não se encontraram definições aprofundadas do conceito expressas pelos participantes. Emerge como aproximação ao conceito a capacidade para interação social ou enquanto fenómeno intrinsecamente relacionada com a religiosidade. A felicidade depende pouco de eventos externos e reforça-se com fatores duradouros e de uma dimensão mais interior e predeterminada previamente à doença. Os fatores que contribuem são essencialmente de ordem pessoal, familiar, suporte social alargado e emocional. Os que contribuem para menorizar a felicidade são de ordem pessoal, efeitos secundários da medicação, escassez de suporte social alargado, disfunção afetiva e emocional. A família não surgiu enquanto fator associado a menor felicidade. CONCLUSÕES:A felicidade está interligada à vivência social e ao bem-estar, à resiliência, a fatores protetores internos da própria pessoa.BACKGROUND: The way each person lives and feels satisfaction with their life experience, naturally has a subjective but revealing dimension of intrinsic aspects of the human dimension. Happiness can be an aggregating concept of these dimensions although difficult to define for people with or without mental illness. AIM: To identify the happiness perception in people with mental illness, the factors that contribute to increase or reduce this perception. METHODS: Integrative Literature Review. Research in international databases, held in August 2016. A set of descriptors and inclusion criteria were used. A final sample of 7 studies, published between 2006-2014, was obtained. RESULTS: There were no in-depth definitions of the concept expressed by participants. It emerges as an approach to the concept, the capacity for social interaction or as an intrinsically phenomenon related to religiosity. Happiness depends little on external events and is reinforced by enduring factors and a more inward and predetermined dimension prior to illness. The factors that contribute are essentially personal, family, extended social support and emotional. Those that contribute to lower happiness are personal, side effects of medication, lack of broad social support, affective and emotional dysfunction. The family did not arise as a factor associated with less happiness. CONCLUSION: Happiness is intertwined with social experience and well-being, with resilience, with person internal protective factors.info:eu-repo/semantics/publishedVersio

    Thought on Food: A Systematic Review of Current Approaches and Challenges for Food Intake Detection

    Nowadays, individuals have very stressful lifestyles, affecting their nutritional habits. In the early stages of life, teenagers begin to exhibit bad habits and inadequate nutrition. Likewise, other people with dementia, Alzheimer’s disease, or other conditions may not take food or medicine regularly. Therefore, the ability to monitor could be beneficial for them and for the doctors that can analyze the patterns of eating habits and their correlation with overall health. Many sensors help accurately detect food intake episodes, including electrogastrography, cameras, microphones, and inertial sensors. Accurate detection may provide better control to enable healthy nutrition habits. This paper presents a systematic review of the use of technology for food intake detection, focusing on the different sensors and methodologies used. The search was performed with a Natural Language Processing (NLP) framework that helps screen irrelevant studies while following the PRISMA methodology. It automatically searched and filtered the research studies in different databases, including PubMed, Springer, ACM, IEEE Xplore, MDPI, and Elsevier. Then, the manual analysis selected 30 papers based on the results of the framework for further analysis, which support the interest in using sensors for food intake detection and nutrition assessment. The mainly used sensors are cameras, inertial, and acoustic sensors that handle the recognition of food intake episodes with artificial intelligence techniques. This research identifies the most used sensors and data processing methodologies to detect food intake.info:eu-repo/semantics/publishedVersio

    Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences

    The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on 18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based researchers who signed it in the short time span from 20 September to 6 October 2016
