11	Listening comprehension : Digital technology and its effect on the L2 learner’s listening comprehension. Larsson, Sofi, Lundberg, Ove January 2019 (has links) The rapid development of new technologies and how these are affecting school age children is in this day and age an area of growing importance. In the context of second language (L2) acquisition, it has been noted that spare time activities of a digital nature impact those pupils who spend more time on activities such as online gaming in the target language than average (Sundqvist 2019, 95-103). The aim of the current study was to investigate the possible effect three different digital spare time activities (computer and video games, movies and music) have on listening comprehension. This when English is the dominant language in the activities, and the focus is on 6th grade children. The method used was a comparison made between a language diary homework, consisting of the participants’ estimated number of hours spent on digital spare time activities, and the results of a listening exercise. The results show that there is a positive correlation between the results of the listening comprehension test and the number of hours spent on digital spare time activities. Also, repeated exposure to the target language in a digital spare time context does, therefore, affect second language acquisition to a limited extent. The conclusion was that in order to come to a more conclusive answer regarding the correlation between digital spare time activities and English listening comprehension, more research is needed. / I samband med andraspråksinlärning har det noterats att digitala fritidsaktiviteter påverkar de elever som spenderar mer tid på denna sorts aktiviteter (Sundqvist 2019, 95–103). Syftet med den aktuella undersökningen blev således att undersöka den möjliga effekt digitala fritidsaktiviteter, på engelska, har på just engelsk hörförståelse. De tre utvalda aktiviteterna är här digitala spel, film och musik. Engelska är alltså målspråket och fokusgruppen är sjätteklassare. Metoden som användes var en jämförelse mellan resultaten av en språkdagbok, bestående av det antal timmar som deltagarna angett att de spenderar på digitala fritidsaktiviteter under en genomsnittlig vecka, samt resultat inhämtade från en hörövning. Resultatet visar att det finns en positiv korrelation mellan resultaten på hörförståelsetestet och antalet timmar som spenderas på digitala fritidsaktiviteter. Vidare visade det sig att upprepad exponering för målspråket i ett digitalt sammanhang påverkar andraspråksinlärning i en begränsad utsträckning. Slutsatsen blev därmed att det krävs mer forskning för att komma fram till ett definitivt svar angående sambandet mellan digitala fritidsaktiviteter och engelsk hörförståelse.

Nela é abordada a implementação da hora-atividade no âmbito da Lei Federal nº 11.738/08, que, em consonância com a LDB (9394/96), reorganiza a jornada docente. O objetivo foi contribuir com a reflexão acerca da implementação das políticas públicas para a formação de professores em serviço a partir da institucionalização da horaatividade com a Lei 11.738/08, analisando limites e possibilidades e propondo um plano de ação que minimizasse as dificuldades identificadas. A pesquisa se propôs a responder quais possibilidades e limites cerceiam a utilização da hora-atividade como espaço formativo, tendo como campo quatro escolas estaduais sediadas na Coordenadoria Regional de Educação de Ouro Preto do Oeste no estado de Rondônia. Caracterizou-se como estudo de caso com abordagem qualitativa, tendo como instrumentos a análise documental, grupos focais e pesquisa bibliográfica. O aporte teórico veio para sustentar o paradigma de formação adotado quando se refere a formação continuada na escola, centrando especialmente em três frentes, sendo a primeira voltada para a implementação de políticas públicas e seus desafios (CONDÉ, 2013; LOTTA, 2010; MAINARDES, 2006); a segunda apresentando reflexões sobre a formação continuada para além das concepções tradicionais, concebendo a escola como lócus formativo, pautando a valorização da aprendizagem em contexto através da reflexão sobre a prática e valorizando a troca entre pares (ALARCÃO, 2001, 2004, 2015; GATTI, 2008, 2009, 2011; NÓVOA, 1992; IMBERNÓN, 2010); a terceira, buscando tecer uma análise sobre a atuação dos gestores escolares no atual contexto educacional (ABRUCIO, 2010; BURGOS e CANEGAL, 2011). Os resultados revelam que a implementação da hora-atividade e sua utilização como espaço formativo apresentam dificuldades, que são depreendidas de questões macro e micro estruturais, dentre outros, fatores atribuídos à ausência de formação para gestores escolares, falhas no processo de monitoramento e avaliação, tempo dos professores e gestores como terreno conflituoso, gestão pedagógica limitante, frágeis concepções acerca da formação continuada na escola, conflitos latentes e evidentes no campo relacional. O estudo também proporcionou a verificação de possibilidades para se efetivar a formação contínua na escola, como: garantias legais, reconhecimento da formação continuada de professores como ação relevante para a educação, reconhecimento dos professores como portadores de direitos que aspiram por formação ao longo da carreira. Possibilitou também o avanço da reflexão teórica sobre as implicações de políticas públicas voltadas para a formação docente e o seu complexo processo de implementação. Para o enfrentamento dos problemas identificados e tendo em vista as prerrogativas da Lei, foi proposto um Plano de Ação Educacional (PAE) compreendido como de possível exequibilidade por demandar pequenas custas à Coordenadoria. Junto ao PAE se apresentam alinhadas algumas recomendações à Secretaria de Estado da Educação (SEDUC/RO) consideradas de impacto positivo frente aos problemas identificados pelo estudo. / This research was developed within the scope of the Professional Master in Management and Evaluation of Education (PPGP) of the Center for Public Policies and Education Evaluation of the Federal University of Juiz de Fora (CAEd / UFJF). It addresses the implementation of houractivity in the scope of Federal Law 11,738 / 08, which, in line with LDB (9394/96), reorganizes the teaching day. The objective was to contribute to the reflection about the implementation of policies for the training of teachers in public service for the training of teachers in service from the institutionalization of the hour-activity with Law 11.738 / 08, analyzing limits and possibilities and proposing a plan that would minimize the identified difficulties. The research proposed to answer what possibilities and limits limit the use of hour-activity as a formative space, having as field four state schools located in the Regional Coordination of Education of Ouro Preto do Oeste in the state of Rondônia. It was characterized as a case study with a qualitative approach, having as instruments the documentary analysis, focus groups and bibliographic research. The theoretical contribution came to support the training paradigm adopted when referring to continuing education in the school, focusing especially on three fronts, the first one focused on the implementation of public policies and their challenges (CONDÉ, 2013; LOTTA, 2010; MAINARDES, 2006); the second presenting reflections on continuing education beyond traditional conceptions, conceiving the school as a formative locus, guiding the valuation of learning in context through reflection on practice and valuing the exchange between peers (ALARCÃO, 2001, 2004, 2015, GATTI , 2008, 2009, 2011, NÓVOA, 1992, IMBERNÓN, 2010); the third, seeking to analyze the performance of school managers in the current educational context (ABRUCIO, 2010; BURGOS and CANEGAL, 2011). The results show that the implementation of time-activity and its use as a training space present difficulties, which are apparent from macro and micro structural issues, among others, factors attributed to the absence of training for school managers, failures in the monitoring and evaluation process, time of teachers and managers as conflictive terrain, limiting pedagogical management, fragile conceptions about continuing education in the school, latent and evident conflicts in the relational field. The study also provided the verification of possibilities for continuing education in the school, such as: legal guarantees, recognition of continuing teacher education as a relevant action for education, recognition of teachers as holders of rights that aspire for training throughout the career. It also allowed for the advancement of theoretical reflection on the implications of public policies aimed at teacher education and its complex implementation process. In order to confront the problems identified and in view of the prerogatives of the Law, an Educational Action Plan (PAE) was proposed as a possible feasibility because it demands small costs for the Coordination. Along with the PAE, some recommendations to the State Secretariat of Education (SEDUC / RO) are presented, which are considered to have a positive impact on the problems identified by the study.

Current conditions of communication routes and public welfare are being analyzed in order to select proper urban model, that would be applied. Two buildings of former dormitories are to be replaced by leisure time activity center and multifunctional house with commercial space and retirement house respectively. The purpose of former canteen will be left as it this, although it is meant to be enhanced by adding cafeteria with roof garden. In the given context, an architectural design was elaborated while using former structures and layout but with new inner structure. Vertical wooden structures with dynamically spaced elements are used as a common feature. Apart from design of the buildings themselves a special care was also taken while creating the environment. Parks are laid out in a polygon grid, shaped by the straight lines of communication routes.
15	Étude par simulation numérique de la sensibilité au bruit des mesures de paramètres pharmacocinétiques par tomographie par émission de positrons Aber, Yassine 08 1900 (has links) La modélisation pharmacocinétique en tomographie par émission par positrons (TEP) permet d’estimer les paramètres physiologiques liés à l’accumulation dynamique d’un radiotraceur. Les paramètres estimés sont biaisés par le bruit dans les images TEP dynamiques durant l’ajustement des courbes d’activité des tissus, plus communément appelées TAC de l’anglais Time Activity Curve. La qualité des images TEP dynamiques est limitée par la statistique de comptage et influencée par les paramètres de reconstruction choisis en termes de résolution spatiale et temporelle. Il n’existe pas de recommandations claires pour les paramètres de reconstruction à utiliser pour les images dynamiques TEP. L’objectif de ce projet de maitrise est d’évaluer le biais dans l’estimation des paramètres pharmacocinétiques afin de trouver les paramètres de reconstruction TEP les plus optimaux en termes de résolution spatiale et de niveau de bruit. Plus précisément, ce projet cherche à déterminer quel modèle d’AIF offre les meilleurs ajustements, mais aussi quel modèle de poids permet la meilleure estimation des paramètres pharmacocinétiques pour le modèle à deux compartiments. Ce faisant, il serait possible de mieux planifier la reconstruction d’images TEP dynamique et potentiellement améliorer leur résolution spatiale. Afin de tester les biais dans les paramètres pharmacocinétiques sous différents niveaux de bruit, un objet de référence numérique (DRO) avec les informations trouvées dans la littérature sera construit. Ensuite, des simulations numériques seront effectuées avec ce DRO afin de trouver les paramètres de reconstruction et le niveau de bruit le plus optimal. Un biais réduit des paramètres pharmacocinétiques et une meilleure résolution spatiale des images TEP dynamique permettrait de détecter des cancers ou tumeurs à des stades moins avancés de la maladie, permettant potentiellement un traitement plus efficace et avec moins de séquelles et d’effets secondaires pour les patients. En outre, cela permettrait aussi de visualiser l’hétérogénéité des tumeurs. / Pharmacokinetic models in positron emission tomography (PET) allow for the estimation of physiological parameters linked to the dynamic accumulation of a radiotracer. Estimated parameters are biased by noise in dynamic PET images during the fitting of Time Activity Curves (TAC). Image quality in dynamic PET is limited by counting statistics and influenced by the chosen reconstruction parameters in terms of spatial and temporal resolution. Clear recommendations and guidelines for the reconstruction parameters that should be used do not exist at the moment for dynamic PET. The goal of this masters project is to evaluate the bias in the pharmacokinetic parameters estimation to find the optimal PET reconstruction parameters in terms of spatial resolution and noise levels. More precisely, this project aims to determine which AIF model produces the best fits, but also which weight noise model allows for the best parameters estimation with the two compartment model. It would then be possible to plan the PET image reconstruction more finely and potentially improve spatial resolution. To test the pharmacokinetic parameters’ biases under different noise levels, a Digital Reference Object (DRO) with information and specifications found from the litterature will be built. Then, numerical simulations will be done with that DRO to find the optimal noise level and value for the pharmacokinetic parameter. A reduced bias in these parameters and an improved spatial resolution would allow the detection of tumors or lesions at earlier stages, which could potentially allow for a more potent treatment with less short and long term side effects. It would also allow the visualization and quantification of lesion heterogeneity.

16	GIS-based Episode Reconstruction Using GPS Data for Activity Analysis and Route Choice Modeling / GIS-based Episode Reconstruction Using GPS Data Dalumpines, Ron 26 September 2014 (has links) Most transportation problems arise from individual travel decisions. In response, transportation researchers had been studying individual travel behavior – a growing trend that requires activity data at individual level. Global positioning systems (GPS) and geographical information systems (GIS) have been used to capture and process individual activity data, from determining activity locations to mapping routes to these locations. Potential applications of GPS data seem limitless but our tools and methods to make these data usable lags behind. In response to this need, this dissertation presents a GIS-based toolkit to automatically extract activity episodes from GPS data and derive information related to these episodes from additional data (e.g., road network, land use). The major emphasis of this dissertation is the development of a toolkit for extracting information associated with movements of individuals from GPS data. To be effective, the toolkit has been developed around three design principles: transferability, modularity, and scalability. Two substantive chapters focus on selected components of the toolkit (map-matching, mode detection); another for the entire toolkit. Final substantive chapter demonstrates the toolkit’s potential by comparing route choice models of work and shop trips using inputs generated by the toolkit. There are several tools and methods that capitalize on GPS data, developed within different problem domains. This dissertation contributes to that repository of tools and methods by presenting a suite of tools that can extract all possible information that can be derived from GPS data. Unlike existing tools cited in the transportation literature, the toolkit has been designed to be complete (covers preprocessing up to extracting route attributes), and can work with GPS data alone or in combination with additional data. Moreover, this dissertation contributes to our understanding of route choice decisions for work and shop trips by looking into the combined effects of route attributes and individual characteristics. / Dissertation / Doctor of Philosophy (PhD) GPS time use diary episode extraction multinomial logit travel behavior mode detection episode reconstruction GIS map-matching route choice path size logit potential path area scale estimation Python ArcGIS activity analysis trip reconstruction smartphone global positioning system geographic information system toolkit work trip shop trip potential activity location land use activity episode travel episode stop episode transferability scalability modularity scripting big data travel survey respondent burden preprocessing multipath error tracking purpose detection segmentation data filter data smoothing fuzzy logic neural network decision tree rule-based algorithm trajectory point road network network dataset gateway shortest path horizontal dilution of precision HDOP commonality factor mode transfer point Halifax Nova Scotia Space-Time Activity Research variance inflation factor shapefile comma-separated values traveling salesman problem data mining branch-and-bound algorithm pedestrian network alternative route observed route route efficiency route attributes distance time heading bearing duration acceleration latitude longitude coordinate overlay analysis intersect shopping module data logger walk likelihood ratio test classification table path generation kappa statistic degrees data collection transportation research automate framework ArcToolbox spatio-temporal navigation positioning trace path spatial data topology horizontal accuracy SPSS Stata spatial resolution temporal resolution household survey trip reporting proximity analysis DMTI Desktop Mapping Technologies Inc. road intersection route overlap left turn right turn location analysis time geography spatial statistics buffer analysis cycling bus transit public transportation GEOIDE AGILE data need raw data urban canyon endpoint data cleaning elevation satellite outliers automatic processing nearest node classifier classification method short trip multi-point
