This work represents an original contribution to the methodology for ecosystem models' development as well as the rst attempt of an end-to-end (E2E) model of the Northern Humboldt Current Ecosystem (NHCE). The main purpose of the developed model is to build a tool for ecosystem-based management and decision making, reason why the credibility of the model is essential, and this can be assessed through confrontation to data. Additionally, the NHCE exhibits a high climatic and oceanographic variability at several scales, the major source of interannual variability being the interruption of the upwelling seasonality by the El Niño Southern Oscillation, which has direct e ects on larval survival and sh recruitment success. Fishing activity can also be highly variable, depending on the abundance and accessibility of the main shery resources. This context brings the two main methodological questions addressed in this thesis, through the development of an end-to-end model coupling the high trophic level model OSMOSE to the hydrodynamics and biogeochemical model ROMS-PISCES: i) how to calibrate ecosystem models using time series data and ii) how to incorporate the impact of the interannual variability of the environment and shing. First, this thesis highlights some issues related to the confrontation of complex ecosystem models to data and proposes a methodology for a sequential multi-phases calibration of ecosystem models. We propose two criteria to classify the parameters of a model: the model dependency and the time variability of the parameters. Then, these criteria along with the availability of approximate initial estimates are used as decision rules to determine which parameters need to be estimated, and their precedence order in the sequential calibration process. Additionally, a new Evolutionary Algorithm designed for the calibration of stochastic models (e.g Individual Based Model) and optimized for maximum likelihood estimation has been developed and applied to the calibration of the OSMOSE model to time series data. The environmental variability is explicit in the model: the ROMS-PISCES model forces the OSMOSE model and drives potential bottom-up e ects up the foodweb through plankton and sh trophic interactions, as well as through changes in the spatial distribution of sh. The latter e ect was taken into account using presence/ absence species distribution models which are traditionally assessed through a confusion matrix and the statistical metrics associated to it. However, when considering the prediction of the habitat against time, the variability in the spatial distribution of the habitat can be summarized and validated using the emerging patterns from the shape of the spatial distributions. We modeled the potential habitat of the main species of the Humboldt Current Ecosystem using several sources of information ( sheries, scienti c surveys and satellite monitoring of vessels) jointly with environmental data from remote sensing and in situ observations, from 1992 to 2008. The potential habitat was predicted over the study period with monthly resolution, and the model was validated using quantitative and qualitative information of the system using a pattern oriented approach. The nal ROMS-PISCES-OSMOSE E2E ecosystem model for the NHCE was calibrated using our evolutionary algorithm and a likelihood approach to t monthly time series data of landings, abundance indices and catch at length distributions from 1992 to 2008. To conclude, some potential applications of the model for shery management are presented and their limitations and perspectives discussed.

The Pennsylvania Adoption Exchange (PAE) helps case workers who represent children in state custody by recommending prospective families for adoption. We describe PAE's operational challenges using case worker surveys and analyze child outcomes through a regression analysis of data collected over multiple years. A match recommendation spreadsheet tool implemented by PAE incorporates insights from this analysis and allows PAE managers to better utilize available information. Using a discrete-event simulation of PAE, we justify the value of a statewide adoption network and demonstrate the importance of better information about family preferences for increasing the percentage of children who are successfully adopted. Finally, we detail a series of simple improvements that PAE achieved through collecting more valuable information and aligning incentives for families to provide useful preference information.

La stratégie actuelle de contrôle de la qualité de l’anode est inadéquate pour détecter les anodes défectueuses avant qu’elles ne soient installées dans les cuves d’électrolyse. Des travaux antérieurs ont porté sur la modélisation du procédé de fabrication des anodes afin de prédire leurs propriétés directement après la cuisson en utilisant des méthodes statistiques multivariées. La stratégie de carottage des anodes utilisée à l’usine partenaire fait en sorte que ce modèle ne peut être utilisé que pour prédire les propriétés des anodes cuites aux positions les plus chaudes et les plus froides du four à cuire. Le travail actuel propose une stratégie pour considérer l’histoire thermique des anodes cuites à n’importe quelle position et permettre de prédire leurs propriétés. Il est montré qu’en combinant des variables binaires pour définir l’alvéole et la position de cuisson avec les données routinières mesurées sur le four à cuire, les profils de température des anodes cuites à différentes positions peuvent être prédits. Également, ces données ont été incluses dans le modèle pour la prédiction des propriétés des anodes. Les résultats de prédiction ont été validés en effectuant du carottage supplémentaire et les performances du modèle sont concluantes pour la densité apparente et réelle, la force de compression, la réactivité à l’air et le Lc et ce peu importe la position de cuisson.

This thesis nalyzes the wayfinding in Landscape Museum of Contemporary Art (MPAC), based on the Institute of Contemporary Art CACI, Minas Gerais, Brazil and the Museum of Contemporary Art of the Serralves Foundation, Porto, Portugal. The study focuses on the interrelationship of the public/visitors with the landscape, architecture and contemporary art museums in these, in order to understand visual perception and apprehension of such an environment for their users. For both were confronted documentation (visual and written) and people talk. The main hypothesis put forward is that the audience/visitor MPAC appreciates the interrelationship between the natural environment (park/garden) and built environment (the works of contemporary art and the galleries), giving equal value to both. To complement this, a second hypothesis is that during the visit to MPACS, visitors define their paths spontaneously, but strongly influenced by existing visual indicators (maps, signage and striking landscape elements), which facilitate the readability of space, which also contribute to the offered services and the experiences of similar institutions. The analytical basis of the research used the concepts of legibility (LYNCH, 2009), wayfinding (GIBSON, 2009; ARTHUR, PASSINI, 2002; WEISMAN, 1982), Experiential Cotinnum (TUAN, 1985), Space Bound (CRUZ PINTO, 2007) and habitus (BOURDIEU, 1992). Methodologically was used qualitative research (DEMO 2000) by means of a case study (YIN, 2005; STAKE, 1999) and participant observation (WHYTE, 2005). In the two institutions interviews with researchers and curators, behavior observation and questionnaires from employees, trainees, monitors and the public/visitor of the two museums were performed. Although partially referende the initial hypothesis, the research showed that the public/visitor value appears more natural environments, they experience a greater intensity and in addition to the factors listed in the second case, your perception and definition of paths suffer significant influence of emotional relations established with space. Generally the audience/visitor adapts easily to different demands of contemporary art exhibition in the two museums and the built environment (park/garden and museum) interferes with your reading path during the visit, perceived by the public/visitor condition as a factor that favors the enjoyment of works on different mounts (wayfinding), though often become a factor that hinders the legibility of the building and its built environment

Este estudo centrou-se num Curso de Licenciatura em Enfermagem e teve como objetivo compreender a influência da relação supervisiva no desenvolvimento da identidade profissional dos estudantes. Os eixos estruturantes que suportam esta investigação e que concorrem para a definição do seu objeto de estudo articulam-se em torno da relação supervisiva, do desenvolvimento de competências profissionais e do desenvolvimento da identidade pessoal e profissional em contexto clínico. A formação desenvolvida através da prática clínica destina-se a preparar indivíduos de acordo com a atual realidade socioprofissional, onde os sujeitos, independentemente da singularidade de cada um, desenvolvem saberes adquiridos em sala de aula. Quando comparada com o espaço escolar, a aprendizagem em contexto clínico é condicionada por fatores que se caraterizam por maior imprevisibilidade e obriga frequentemente o estudante a confrontar-se com situações únicas e impares. A identidade dos estudantes torna-se assim construída e vivida a partir de um conjunto de dimensões que ocorrem no decurso das vivências clínicas. Metodologicamente optou-se por um estudo etnográfico no âmbito do paradigma qualitativo, numa abordagem longitudinal segundo a lógica do estudo de caso. A natureza dos dados a recolher englobou ainda o recurso a procedimentos de natureza quantitativa. Como técnica de recolha de dados recorremos à observação participante, entrevistas semiestruturadas e questionários. O estudo desenvolveu-se numa Escola Superior de Enfermagem da Zona Norte do país e fizeram parte da população 69 estudantes de uma turma de segundo ano, quatro tutores e um professor. O plano de estudo da referida escola está organizado de forma a que a aprendizagem dos estudantes seja progressivamente integradora de saberes interligando a componente teórica com a componente prática. Assim, os ensinos clínicos estão distribuídos entre o 2º e o 4º ano. Da análise e discussão dos dados e subsequentes conclusões ressalta que, quer a relação supervisiva, quer os contextos clínicos, foram influenciadores do desenvolvimento de competências profissionais, bem como da identidade pessoal e profissional dos estudantes. Verificamos que os dois contextos clínicos estudados – medicina e cirurgia – favoreceram o desenvolvimento de competências distintas, no entanto complementares. Tornou-se visível que, os supervisores do contexto de medicina, possuidores de uma visão holística da profissão de enfermagem, promoveram nos estudantes uma visão integradora do doente, resultante de uma contínua atitude reflexiva sobre a Pessoa Humana. Por sua vez, no contexto de cirurgia, caraterizada por intervenções mais invasivas e mais centradas no tratar, as competências mais valorizadas pelos tutores, embora que de uma forma não verbalmente assumida, foram do domínio técnicocientífico, com especial relevo pelas competências instrumentais.

The consequences resulting from economic modernization model generated social and environmental imbalances, resulting in the exclusion and social isolation, perceived consequences in the agricultural sector. When studying social organizations, tends to see how they keep their forward cooperation processes all a company incorporated by the appreciation of individualism and competition. The overall objective for this research was to analyze the organizational dynamics of Agroecology Group Heritage Viva Chapecó, Santa Catarina, in order to identify the strengths and threats and collaborate in this way for preparation of action strategies for sustainability. The selected group is based on the principles of agroecology for the conduct of their agricultural production systems, avoiding the use of agrochemicals, proven through the use of participatory certification seal Ecovida Network, and the products sold mainly in street fairs in the city of chapecó. To fulfill such a proposal were consulted the minutes of meetings and questionnaires with farmers to assess the dynamics of cooperation among its members, through the understanding of their social capital and social network analysis (SNA). To extend the study of the group and its members was adopted methodological approach of action research where activities were developed to identify strengths and weaknesses and contribute to its organizational restructuring, resulting in the construction, carried out by farmers, the guiding principles of the Living Heritage Group will contribute to the decision-making and strengthen their identity. The survey also brought the group is inserted in the Social Transition Agroecology therefore change the current paradigm is not inserted only in the alternative model of production, but in the form of organization of social actors and their role in the marketing process of their products, in discussing the scenario of food supply chains.

This paper aims to evaluate the factors related to food that influence tourists to choose a particular destination. The secondary aim is to identify how tourists perceive food in relation to the culture of the destination. Does the tourist see gastronomy as a way to know the local culture? Is this fact significant when choosing a destination? A hypothetical-deductive methodology combined with descriptive statistics, with the application of a survey instrument resulted in 400 structured interviews and questionnaires valid for each year. The survey covered the summers of 2006 and 2011 in the city of Balneário Camboriú, Santa Catarina, Brazil. With the results in hand it was possible to create three group of tourists with singular characteristics related to gastronomy, which allowed the definition of the concepts Gourmet Customer, Appreciation Customer and Food Customer, each with a specific perception of the importance of gastronomy and culture within tourism.

O presente artigo tem como objetivo refletir sobre o impacto das TIC em contexto educativo, focando os potenciais contributos da utilização dos Recursos Educativos Digitais (RED) no processo de ensino e de aprendizagem. Para o efeito, são apresentados os resultados da utilização do RED: Aula Digital - O Mundo da Carochinha 1.º Ano. O estudo foi concretizado numa turma do 1.° ano de escolaridade do 1.º CEB, constituída por 27 alunos, com idades e compreendidas entre os 6-7 anos, num Agrupamento de Escolas da Cidade de Castelo Branco, no âmbito da Prática de Ensino Supervisionada. Os resultados obtidos, após a análise e tratamento dos dados, permitiram concluir que ao utilizar este RED os alunos demonstraram terem adquirido os conteúdos abordados, pelo facto de se terem potenciado níveis de maior interesse, empenho, motivação, envolvimento e espírito de iniciativa no decorrer das atividades propostas. Porém, talvez pelo facto de serem alunos de 1º ano do 1º CEB, não descuram a presença e o acompanhamento da professora e a utilização de recursos em suporte papel. Quer isto dizer que deve haver uma complementaridade que concilie o fator humano (professora), com a utilização de recursos em suporte digital (RED) e recursos em suporte papel (Manual). Traduzindo, desta forma, uma rentabilização dos recursos pedagógicos conducentes a uma melhoria do processo de ensino e de aprendizagem.

Rimicaris exoculata is a deep-sea hydrothermal vent shrimp which enlarged gill chamber houses a complex trophic epibiotic community. Its gut harbours an autochthonous and distinct microbial community. This species dominates hydrothermal ecosystems megafauna along the Mid-Atlantic Ridge, regardless of contrasted geochemical conditions prevailing in them. Here, the resident gut epibiont community at four contrasted hydrothermal vent sites (Rainbow/TAG/Logatchev/Ashadze) was analysed and compiled with previous data to evaluate the possible influence of site location, using 16S rRNA surveys and microscopic observations (TEM, SEM and FISH analyses). Filamentous epibionts inserted between the epithelial cells microvilli were observed on all examined samples. Results confirmed resident gut community affiliation to Deferribacteres, Mollicutes, Epsilonproteobacteria and to a lesser extent Gammaproteobacteria lineages. Still a single Deferribacteres phylotype was retrieved at all sites. Four Mollicutes-related OTUs were distinguished, one being only identified on Rainbow specimens. The topology of ribotypes median-joining networks illustrated a community diversification possibly following demographic expansions, suggesting a more ancient evolutionary history and/or a larger effective population size at Rainbow. Finally, the gill chamber community distribution was also analysed through ribotypes networks based on sequences from R. exoculata collected at Rainbow/Snake Pit/TAG/Logatchev/Ashadze sites. Results allow refining hypotheses on the epibiont role and transmission pathways.
