    The essence of a city is its citizens and communities. A city’s infrastructure and associated services play a vital role in citizens' day-to-day living and their overall quality of life. Traditionally, services are deployed in a top-down approach where authorities, councils and public bodies take a reactive approach to address community needs and concerns. In this paper, we propose our ‘Citizen Observatory’ approach to enable citizens to take a proactive role in the management of their local communities and environment by supporting their engagement in the decision-making process. We discuss how to empower citizens and communities to engage with and assist authorities to establish a more informed understanding of residents’ needs and the status of their local environments. Through the WeSenseIt project, we employ a location-based crowdsourcing and communication strategy to develop a resilient, efficient and collaborative information ecosystem for decision-making in urban and rural areas

    Tese de doutoramento em Biociências, no ramo de Ecologia Marinha, apresentada ao Departamento de Ciências da Vida da Faculdade de Ciências e Tecnologia da Universidade de CoimbraIn the face of the current non-linear and abrupt changes in ecosystems around the world, a systematic impact has arisen to the environmental dynamics of the coastal systems. At their essential intermediate trophic level in the marine system, sardines are recognized for being highly susceptible to the deregulation of their stocks when subjected to intensive exploitation. Given this, there are significant difficulties of management and participatory coastal management of the species of sardines in the Atlantic Ocean. In this way, local ecological knowledge (LEK) emerges as an auxiliary tool that seeks to extract specific information about an individual about the environment as well as to understand the attitudes of local individuals regarding a resource as a way to improve biodiversity conservation practices. Therefore, the present thesis sought to evaluate and share local ecological knowledge (LEK) and attitudes for the conservation of European pilchard (Sardina pilchardus) and Brazilian sardine (Sardinella brasiliensis) in two fishing villages (Peniche, District of Leiria, Portugal and Arraial do Cabo, State of Rio de Janeiro, Brazil). This study was based on 221 semi-structured interviews conducted with fishermen from Peniche (N = 87) about European sardines, and with fishers from Arraial do Cabo (N = 134) about Brazilian sardine. The data extracted from the interviews were qualitatively and quantitatively analysed, and the LEK made available was compared with the literature following an emic-etic approach. Additives knowledge indicators and attitudes about sardines were created for comparison purposes. The classification adopted to evaluate the LEK, and the attitudes respected the premises of the three-point Likert scale. It was also sought to investigate possible correlations between LEK, attitudes and the profile of fishers from both communities. The statistical treatments performed were calculated using program R version 3.3.2. The profiles of the interviewees of the studied communities were investigated and measured succinctly. Informants shared detailed informal knowledge of the significant biological and ecological aspects of the clupeoids in question. Taboos and food aversions were present inexpressively and were not related to conservation measures. Fishers from both Atlantic communities presented moderate local ecological knowledge about sardines when compared to the biological data already published of this small pelagic species. Attitudes towards conservation of sardines were classified as positive in Peniche, while in the Brazilian community analyzed, they were moderate. In Peniche, attitudes showed to be a predictor of LEK, age and educational level of informants. Otherwise, in Arraial do Cabo the variables of the fisher´s profile (source of income, educational level, boat ownership, association with fishing colony and occupation) showed a correlation with LEK and with conservationist attitudes. Encouraging the continuation of regular educational training of informants and the inclusion of environmental education programs with the sharing of information on sardine conservation. This ethnobiological study reported comparable results with other studies examining LEK and local community attitudes about a natural resource, which reaffirms the importance of this socio-ecological tool for environmental management. Informal knowledge not compatible with the literature should not be discarded. This type of information can be further analysed and used in the formulation of testable hypotheses for future investigations of the species studied. The next step would be to include the LEK provided by the surveyed communities for analysis at meetings between all actors directly involved with the fishing resource. This procedure can collaborate and promote greater social inclusion of the less favored in the fisheries management decision-making in the Portuguese and Brazilian communities verified. A discussion with the participation of all the interested parties, without preconceived privileges to any of those involved, becomes of extreme importance because it enables reliability among the participants of these assemblies. This process, if well conducted, still can generate a better understanding of the predisposition of these communities to conserve the environmental resource. Also, this participatory management strategy may also provide an opportunity for local populations to acquire reliable and more scientific knowledge about this depleting fishing resource. Finally, a continuous exchange of information between ecologists and ethnobiologists is suggested on possible gaps in knowledge that may arise about fish stocks in both Atlantic systems.Em virtude das actuais mudanças não-lineares e abruptas nos ecossistemas em todo o planeta, a dinâmica ambiental dos sistemas costeiros tem sido bastante modificada. Por ocuparem o nível trófico intermediário essencial no sistema marinho, as sardinhas são reconhecidas por serem altamente susceptíveis a grandes alterações dos seus efectivos populacionais quando submetidas à exploração intensiva. Diante de tal cenário, observam-se grandes dificuldades na gestão costeira (que se quer participativa) das espécies de sardinhas no oceano Atlântico. Desse modo, o conhecimento ecológico local (CEL) surge como uma ferramenta auxiliar que busca extrair informações específicas de um indivíduo em relação ao meio ambiente como também compreender as atitudes de indivíduos locais no que tange a um recurso em particular, como forma de melhorar as práticas de conservação da biodiversidade. Por conseguinte, a presente tese tentou avaliar o conhecimento ecológico local (CEL), bem como as atitudes para a conservação da sardinha europeia (Sardina pilchardus) e da sardinha brasileira (Sardinella brasiliensis) em duas aldeias piscatórias (Peniche, Distrito de Leiria, Portugal; e Arraial do Cabo, Estado do Rio de Janeiro, Brasil). Este estudo baseou-se em 221 entrevistas semiestruturadas realizadas aleatoriamente com pescadores de Peniche (N = 87) acerca da sardinha europeia, e com pescadores de Arraial do Cabo (N = 134) sobre a sardinha brasileira. Os dados extraídos das entrevistas foram analisados de modo qualitativo e quantitativo e o CEL disponibilizado foi comparado com a literatura através da utilização das abordagens êmica e ética. Foram criados índices para medir o CEL e as atitudes dos pescadores em relação à conservação das espécies de sardinhas. A classificação adotada para avaliar o CEL e as atitudes respeitou as premissas da escala de três pontos de Likert. Por último, também foram investigadas as possíveis correlações entre CEL, atitudes e o perfil dos pescadores de ambas as comunidades. Os tratamentos estatísticos realizados foram calculados por meio do programa R versão 3.3.2. Os perfis dos entrevistados das comunidades estudadas foram investigados e analisados sucintamente. Os entrevistados compartilharam conhecimentos informais detalhados dos principais aspectos biológicos e ecológicos dos clupeóides em questão. Os tabus e aversões alimentares estiveram presentes de forma inexpressiva e não foram relacionados com medidas conservacionistas. Os pescadores de ambas as comunidades Atlânticas apresentaram um conhecimento ecológico local moderado acerca das sardinhas quando comparados aos dados biológicos já publicados dessas pequenas espécies pelágicas. Em Peniche, houve a correlação entre as atitudes e o CEL, a idade e o nível educacional dos informantes respectivamente. Por outro lado, em Arraial do Cabo as variáveis do perfil dos pescadores (fonte de renda, nível educacional, propriedade de embarcação, associação à colónia de pescadores e ocupação) mostraram correlação com o CEL e com as atitudes conservacionistas. O incentivo à continuação da formação educacional convencional dos informantes (pescadores) e a inserção de programas de educação ambiental acompanhados de informações acerca da conservação da sardinha nas aldeias de pescadores investigadas são essenciais para estabelecer e melhorar as atitudes conservacionistas. Este estudo etnobiológico reportou resultados comparáveis com outros estudos que investigam o LEK e atitudes de comunidades locais acerca de um determinado recurso natural, o que reafirma a importância desta ferramenta sócio-ecológica para a gestão ambiental. O conhecimento informal não compatível com a literatura não deve ser totalmente descartado. Esse tipo de informação pode ainda ser analisado minuciosamente e utilizado na formulação de hipóteses para futuras investigações acerca da espécie estudada. O próximo passo seria incluir o CEL fornecido pelas comunidades estudadas para análises em reuniões entre todos os atores envolvidos directamente com o recurso pesqueiro. Esse procedimento pode promover uma maior inclusão social dos menos favorecidos nas decisões relativas à gestão dos stocks pesqueiros nas comunidades portuguesa e brasileira. Uma discussão com a participação de todos os interessados, sem privilégios preconcebidos a nenhum dos envolvidos, torna- se de extrema importância pois aumenta a confiança entre todos os envolvidos. Este processo, se bem conduzido, ainda tem a capacidade de gerar um melhor entendimento da predisposição dessas comunidades em conservar o recurso ambiental. Além disso, esta estratégia de gestão participativa também pode proporcionar uma oportunidade das populações locais adquirirem conhecimentos mais científicos sobre esse recurso pesqueiro em questão. Por fim, sugere-se ainda uma contínua troca de informações entre ecólogos e etnobiólogos sobre as possíveis lacunas de informações que possam surgir relativamente aos stocks pesqueiros em ambos os sistemas Atlânticos.Centre for Functional Ecology - CFE, Department of life Sciences, University of Coimbra, PortugalProject ReNATURE - Valorization of the Natural Endogenous Resources of the Centro Region (Centro 2020, Centro-01-0145-FEDER-000007)CAPES Foundation – Ministry of Education of Brazil for financial support (BEX: 8926/13-1

    Citizens observatories for effective Earth observations: the WeSenseIt approach

    The WeSenseIt project defines citizen observatories as “A method, an environment and an infrastructure supporting an information ecosystem for communities and citizens, as well as emergency operators and policymakers, for discussion, monitoring and intervention on situations, places and events” . A collaborative approach has been taken to develop solutions that involve an exchange of information and expertise from all participants and where the focus is on arriving at practical solutions with a clear vision and direction. This has created a shared ownership scheme, and shifts power to the process itself rather than remaining within authorities, developers or decision-makers. The project’s emphasis is on delivering highly innovative technologies to support citizens, communities and authorities in developing a real-time situation awareness while ensuring all stakeholders play their part. Implementation has been through a combination of crowdsourcing, custom applications and dedicated web portals designed to foster collaboration, and which has created a shared knowledge base that facilitates decision-making processes and engages with communities. Data is captured via innovative sensors that are used directly by citizens, crowdsourcing from social networks (or by collective intelligence)

    Technical validation of real-world monitoring of gait: a multicentric observational study

    Introduction: Existing mobility endpoints based on functional performance, physical assessments and patient self-reporting are often affected by lack of sensitivity, limiting their utility in clinical practice. Wearable devices including inertial measurement units (IMUs) can overcome these limitations by quantifying digital mobility outcomes (DMOs) both during supervised structured assessments and in real-world conditions. The validity of IMU-based methods in the real- world, however, is still limited in patient populations. Rigorous validation procedures should cover the device metrological verification, the validation of the algorithms for the DMOs computation specifically for the population of interest and in daily life situations, and the users’ perspective on the device. Methods and analysis: This protocol was designed to establish the technical validity and patient acceptability of the approach used to quantify digital mobility in the real world by Mobilise-D, a consortium funded by the European Union (EU) as part of the Innovative Medicine Initiative, aiming at fostering regulatory approval and clinical adoption of DMOs. After defining the procedures for the metrological verification of an IMU-based device, the experimental procedures for the validation of algorithms used to calculate the DMOs are presented. These include laboratory and real-world assessment in 120 participants from five groups: healthy older adults; chronic obstructive pulmonary disease, Parkinson’s disease, multiple sclerosis, proximal femoral fracture and congestive heart failure. DMOs extracted from the monitoring device will be compared with those from different reference systems, chosen according to the contexts of observation. Questionnaires and interviews will evaluate the users’ perspective on the deployed technology and relevance of the mobility assessment. Ethics and dissemination: The study has been granted ethics approval by the centre’s committees (London—Bloomsbury Research Ethics committee; Helsinki Committee, Tel Aviv Sourasky Medical Centre; Medical Faculties of The University of Tübingen and of the University of Kiel). Data and algorithms will be made publicly available

    Decision graphs: Managing decisions for emergencies

    No full text
    Emergencies are highly complex situations that require careful consideration of information collected from a variety of sources, by a variety of individuals and agencies. Good situation awareness provides the basis for a highly effective decision-making process requiring large volumes of real time information. Processing this is a highly complex task, and the dynamic nature of emergencies introduces further challenges. Over the years, several initiatives have attempted to address this complexity by proposing a variety of solutions that have contributed to a growing field of research. While progress toward decision-making support has been significant, the process of managing decisions has received less attention. To learn from decisions, there needs to be a process of collecting, curating and analyzing decision-making itself. Information being collected via a large number of resources needs to be formalized and interpreted by the decision maker, who in turn combines the information collected with their own knowledge and experience to make critical, and often life-saving decisions. Many of the decisions need to be taken instantaneously, while some need careful consultation and consideration, in collaboration with experts only once good situation awareness is achieved. This process of taking decisions based on evidence and personal experience is often lost, mostly due to lack of appropriate archiving mechanisms (e.g. not digitizing paper-based decisions or recording informal decisions). Therefore post-event analysis and auditing activities can lose track of how decisions were made, their associated evidences and rationale. Recording decisions in real-time, as they are taken, can provide a step change in the way decision support systems can aid future events or post-event analyses. We address this aspect of decision support by proposing a real-time decision capture and monitoring approach, Decision Graphs. At the core of Decision Graphs resides a decision management framework, employing semantic web techniques to organise decisions, as and when they are taken. While Semantic Web approaches have been employed in the past in Decision-Making for Emergency Response, management of decisions using Semantic Technologies has been largely limited. Lightweight decision loggers are deployed in a variety of ways – mobile applications available for all types of mobile devices, web browser-based plugins, and a dedicated web site. The decision loggers capture decisions and all related evidence and rationale from the decision maker, and make them available to the decision management framework. Following an event, a decision maker can then retrieve all decisions via a web-based solution. In this poster, we first present requirements gathered from interviews with a variety of stakeholders. We then address this need and propose a decision management framework that employs a variety of pervasive lightweight decision loggers and semantic web technologies for enriching and organizing decisions. Finally, we present our visualisation mechanisms to help look up events and decisions, during follow-up post event analyses activities

    An Experimental Study on Boundary Classification Algorithms for Information Extraction using SVM

    This paper investigates the incorporation of diverse features in boundary classification algorithms for IE using SVM. Our study reveals that the use of rich data resources greatly contributes to the performance of IE systems and it is more likely to explain the differences in performance reported by several systems than the design decisions relative to the learning model. Evaluation of our system shows an improvement over the state-of-art on a standard dataset using the same data resources but a much simpler learning model than the previously best-reported system.
