Overview of ImageCLEF 2018: Challenges, Datasets and Evaluation

This paper presents an overview of the ImageCLEF 2018 evaluation campaign, an event that was organized as part of the CLEF (Conference and Labs of the Evaluation Forum) Labs 2018. ImageCLEF is an ongoing initiative (it started in 2003) that promotes the evaluation of technologies for annotation, indexing and retrieval with the aim of providing information access to collections of images in various usage scenarios and domains. In 2018, the 16th edition of ImageCLEF ran three main tasks and a pilot task: (1) a caption prediction task that aims at predicting the caption of a figure from the biomedical literature based only on the figure image; (2) a tuberculosis task that aims at detecting the tuberculosis type, severity and drug resistance from CT (Computed Tomography) volumes of the lung; (3) a LifeLog task (videos, images and other sources) about daily activities understanding and moment retrieval, and (4) a pilot task on visual question answering where systems are tasked with answering medical questions. The strong participation, with over 100 research groups registering and 31 submitting results for the tasks, shows an increasing interest in this benchmarking campaign

Stock Market Random Forest-Text Mining (SMRF-TM) Approach to Analyse Critical Indicators of Stock Market Movements

The Stock Market is a significant sector of a country’s economy and has a crucial role in the growth of commerce and industry. Hence, discovering efficient ways to analyse and visualise stock market data is considered a significant issue in modern finance. The use of data mining techniques to predict stock market movements has been extensively studied using historical market prices but such approaches are constrained to make assessments within the scope of existing information, and thus they are not able to model any random behaviour of the stock market or identify the causes behind events. One area of limited success in stock market prediction comes from textual data, which is a rich source of information. Analysing textual data related to the Stock Market may provide better understanding of random behaviours of the market. Text Mining combined with the Random Forest algorithm offers a novel approach to the study of critical indicators, which contribute to the prediction of stock market abnormal movements. In this thesis, a Stock Market Random Forest-Text Mining system (SMRF-TM) is developed and is used to mine the critical indicators related to the 2009 Dubai stock market debt standstill. Random forest and expectation maximisation are applied to classify the extracted features into a set of meaningful and semantic classes, thus extending current approaches from three to eight classes: critical down, down, neutral, up, critical up, economic, social and political. The study demonstrates that Random Forest has outperformed other classifiers and has achieved the best accuracy in classifying the bigram features extracted from the corpus

Improving Access and Mental Health for Youth Through Virtual Models of Care

The overall objective of this research is to evaluate the use of a mobile health smartphone application (app) to improve the mental health of youth between the ages of 14–25 years, with symptoms of anxiety/depression. This project includes 115 youth who are accessing outpatient mental health services at one of three hospitals and two community agencies. The youth and care providers are using eHealth technology to enhance care. The technology uses mobile questionnaires to help promote self-assessment and track changes to support the plan of care. The technology also allows secure virtual treatment visits that youth can participate in through mobile devices. This longitudinal study uses participatory action research with mixed methods. The majority of participants identified themselves as Caucasian (66.9%). Expectedly, the demographics revealed that Anxiety Disorders and Mood Disorders were highly prevalent within the sample (71.9% and 67.5% respectively). Findings from the qualitative summary established that both staff and youth found the software and platform beneficial

Identity, tradition and fashion-able challenges

Tese de Doutoramento em Design, com a especialização em Design apresentada na Faculdade de Arquitetura da Universidade de Lisboa para obtenção do grau de Doutora.Situada no cruzamento disciplinar do design, sustentabilidade, história, antropologia, estudos de cultura material, da moda e do vestir, esta tese confirma que a capulana é mais que um mero pano rectangular estampado industrialmente. É a indumentária nacional através da qual as Moçambicanas preservam e, ao mesmo tempo, atualizam as suas tradições e o seu sentido de pertença, a sua Moçambicanidade. O presente estudo parte duma pesquisa teórica aplicada sobre este pano, e é dividido em três fases cronológicas distintas. O passado, revelando a história da capulana para compreender a sua evolução no contexto das rotas comerciais do Índico. O presente, coolhunting, incluindo trabalho de campo e pesquisa de mercado em Maputo, situa a análise sobre a produção e o consumo da capulana. E o futuro, onde a capulana fashion-able é retratada na sua expressividade cultural e como instrumento passível de práticas de Design para a Sustentabilidade (D4S); esta última parte foi essencialmente realizada na grande Lisboa. Esta análise conclui que em Maputo, o status quo do pano tradicional é reiterado diariamente pela combinação de novas formas de vestir e pensar a capulana num diálogo constante com a roupa “estrangeira”, produzindo estilos e modas outros. Uma prática de vestir que aqui se defende como fashion-ability ou a habilidade de fazer moda. Sempre permeável, versátil e adaptável, a capulana é objeto do que se intitula nesta tese uma “tradição dinâmica”. Uma tradição sólida, porém, não estática. Ao longo dos tempos a capulana tem-se ajustado às influências quotidianas e ocasionais, dinâmica e permanentemente. Até à data, seja no seu contexto original seja no da diáspora, o pano é utilizado tanto na sua forma cortada como por inteiro. Contudo, hoje em dia, a “amarração” do pano é vista pelas novas gerações como antiquada, enquanto a sua forma cortada oferece maior e melhor resposta às exigências de se “ser moderno”. Esta pesquisa D4S, contemplou vários problemas socioculturais observados tanto em Maputo como em Lisboa. Sejam: as frágeis cadeias de design e produção; o papel dos alfaiates, as suas condições de educação (informal) e empregabilidade; como a tendência das jovens designers de moda para uma capulana cortada que abandona a tradicional forma de vestir o pano drapeado, enrolado e amarrado em torno do corpo. Neste contexto, o presente estudo tem como principal objetivo encontrar metodologias D4S para capturar - tanto funcional quanto simbolicamente - a dinâmica da tradição da capulana e desenvolver ações que, a partir do conceito fashion-able e através do (re) uso criativo da capulana, fortaleçam a identidade e sustentabilidade cultural da Diáspora em Lisboa. Ao identificarem-se os alfaiates Africanos e as jovens designers de moda Africanas como principais mediadores que transformam, traduzem, distorcem e modificam a significância do pano, pergunta-se: (1) como pode a moda quotidiana baseada na tradição de capulana contribuir para reforçar processos de identidade e a sustentabilidade cultural na diáspora? (2) como pode ser reforçado o papel do alfaiate Africano tanto em Maputo, como em Lisboa? (3) como pode o ofício de alfaiate ser reapropriado por um sistema de educação formal que atualiza os conhecimentos e habilidades dos alfaiates Africanos em Lisboa? E, finalmente (4) como pode o modo tradicional de vestir a capulana – como um rectângulo de tecido – ser atualizado de forma a reintroduzi-lo no sartório contemporâneo Africano? Com base numa metodologia teórico-prática combina-se uma análise histórica com uma pesquisa-ação-participativa para melhor contextualizar e mapear diferentes práticas atuais de vestir capulana e para desenvolver, posteriormente, em Lisboa dois laboratórios criativos: EPAT e Capulanar. Aqui, reconhecem-se os conceitos Co-design, Slow-fashion e Afetividade como conceitos culturais da capulana, para assim confirmar que as novas expressões criativas situadas em torno da fashion-ability do tecido tradicional podem ser a chave para a sustentabilidade do próprio pano. Contribuindo para um espaço de reflexão sobre as metodologias D4S, identidade, tradição e práticas fashion-able, esta tese conclui que o Conhecimento Cultural é uma das dimensões que consolidam estes quatro conceitos. Em paralelo permite repensar a ability do pano cujos resultados espelham a identidade africana e contribuem para uma mais eficaz sustentabilidade cultural das próprias comunidades envolvidas. Este trabalho procurou, em suma, alcançar o impacto positivo onde a moda, o design, a criatividade, a inovação e a sustentabilidade podem coexistir.ABSTRACT: The present study focuses on the role Design for Sustainability (D4S) methodologies play in defining fashion-able practices based on capulana’s “moving tradition” to reinforce identity processes and cultural sustainability in Lisbon’s diaspora context. Situated at the disciplinary intersections of design, sustainability, anthropology, material cultural studies, history, fashion and dress studies, this D4S approach takes on two creative and pedagogical practical applications, which simultaneously uses creative collaboration as a methodological strategy and Cultural knowledge as a tool to Co-design products that embody Affectivity and, for that matter, are driven towards Slow-fashion. Both theoretical and practical, this approach combines historical analysis with participatory action research to further contextualize and map out the complexities of capulana’s dress practices performed by African tailors and emergent African women fashion designers in Maputo and Lisbon. With the underlying questions: (1) How can tailoring be re-appropriated by a ‘formal’ education system upgrading the knowledge and skills of African tailors in Lisbon? (2) How can the traditional way of wearing capulana – as a rectangle of fabric – be updated in order to reintroduce it in contemporary African sartorial? Contributing to a space for inquiry on identity, tradition and fashion-ability, this thesis finally concludes that if we use Cultural Knowledge from the main agents in capulana’s innovation, we may be able to re-think the potential sustainability behind these practices and also propose results that can mirror the affirmation of African identity. Capulana‘s Slow-fashion, Co-design and Affectivity, as core cultural concepts, are therefore essential guidelines to develop sustainable solutions around both the re-usage of the cloth – in its, more or less, traditional (un)cut forms – and the fragile chains of design, production and consumption, especially by younger generations of consumers. Hence, this work looks forward to achieve the kind of positive impact where fashion, design, creativity, innovation and sustainability can co-exist.N/

Comparative study of renewable energy policies between Ecuador and Germany. Shifting from FITs to Auctions

Policy measures are essential tools for the transition from fossil fuels to renewable energy sources in the electricity generation. Feed-in tariffs (FITs) are the most used policy for support of renewable technologies globally. Nevertheless, Ecuador phased-out FITs in 2016 and adopted auctions in 2015. Ecuador’s implementation of auctions reflects an approach with little relation to practices in other countries and without a technology-specific design. On the other hand, Germany demonstrates a long trajectory in policy-making with vast experience in FITs. Moreover, in 2017 Germany adopted auctions as the official policy to support renewable projects with a scope larger than 750 kW. However, FITs are still in use and complement auctions. This thesis analyses and compares the country-specific contexts where these policies are implemented through the lens of a multi-level perspective framework. As a result, the most important success factors in Germany have been identified: long-term planning, institutional continuity, legislative stability and principally an actively participating society, which is environmentally aware. Obstacles for the transition in Ecuador are institutional discontinuity, legislative inconsistency, the lack of long-term planning and absence of society as actors of the transition. Due to Germany’s pioneering role plus the successful growth of renewable sources during the last twenty years, their policy implementations appear desirable to adopt in other contexts. Therefore, a prospective transferability of the auction policy from Germany to Ecuador is additionally analyzed

After Conversion

This book deals with the religious and ideological consequences of mass conversion in Iberia - where Jews and Muslims were forcibly converted or expelled at the end of the XVth century and beginning of the XVIth- and most specially with the relationship between origins and faith. It also deals with the consequences of coercion on intellectual debates and on the production of knowledge and addresses questions such as dissimulation, dissidence, religious doubt and unbelief

British Essentialism in Eighteenth-Century British Travel Literature of the West Indies and North America

This dissertation explores issues of representation and cultural negotiation by examining how the white colonial other was depicted in eighteenth-century travel literature, specifically Janet Schaw’s Journal of a Lady of Quality written during the years 1774 to 1776. Travel narratives and histories speak to many different topics, yet they reveal the most about eighteenth-century British ways of thinking about race and national identity, more so than about the various peoples and cultures they seek to describe. I argue that this literature reveals a hierarchy based on the absorption and consumption of British practices and goods by the colonial subject. Neither physical appearance, ethnicity, nor gender carried as much weight in the mind of the British observer as did the colonial subjects’ acceptance or rejection of British customs and consumer goods. While adoption of British deportment did not erase differences in race or class, those individuals that emulated British manners and practices were depicted more favorably than those who did not, regardless of social class, political affiliations, or ethnicity. Thus, this dissertation argues that eighteenth-century British essentialism was not founded on location, or social class, but on shared manners, memories, and connections

The art of streamflow forecasting over Europe

While floods are among the most damaging natural hazards, they have helped shape human developments over the last millennia, fostering scientific understanding and technological advances in an attempt for their mitigation. We now more skilfully predict floods at increasing lead times, through probabilistic hydro-meteorological forecasting. But we are now facing new challenges. Have we reached the limits of predictability with seasonal streamflow forecasting? This thesis contributed to the implementation and design of operational seasonal streamflow outlooks, as part of the European and the Global Flood Awareness Systems. Openly available, they give users an overview of potential streamflow changes on sub-seasonal to seasonal timescales. The analysis of both systems highlighted current limits in seasonal predictability and the importance of initial hydrological conditions and the land surface memory. To tackle these limits of predictability, a sensitivity analysis was developed to guide developments for tangible future seasonal streamflow forecast improvements. Are technical and scientific advances increasing faster than the rate at which forecasts are usable for decision-making? As shown by the application of serious games and research interviews at the Environment Agency (to guide a successful transition to probabilistic forecasts for flood early warning in England), science (e.g. forecast skill) is not necessarily a limiting factor for decision-making. Improved communication between scientists and decision-makers, aimed for instance at understanding the complex landscape in which decision-makers operate, is key to a successful adoption of the latest science in practice. Art can help bridge the communication gap, and this thesis culminated in an art exhibition, ‘Gambling with floods?’, at The Museum of English Rural Life (Reading, UK) from 1 to 15 November 2019, created to reach a wide audience. Overall, this thesis has shown that a closer interaction between decision-makers, scientists and artists is urgently needed for a co-leadership on improving science for society
