Full textAbstract:
The topic of the project has been about how the time spent during transport could take on a more engaging and active form; physically as well as mentally. The initial inspiration for this is the changing landscape of mobility, where technologies such as autonomous and shared systems, could allow for purpose specific vehicles rather then personally owned ones. The project investigates how a subscription based business model could help a global mass-market brand, like Volkswagen to stay true to its brand essence. The project is set in 2039’s megacities and is describing a scenario, where Volkswagen sets out to emphasise the ‘Volk’ in its name, by offering a whole new range of purpose specific vehicles, which the user then can pick and book at any given time. During the creative process both analogue and digital tools were used to explore form, function and the overall experience. Full-scale physical mocks-ups and 3D software models where additionally used to validate proportions, scale and concept principles. Working from the Volkswagen design studio gave valuable insights into the brand heritage and design inputs from the design team. The result is an active mobility vehicle concept called, (((O))), which allows its users to spent their transport time in an more engaging way. Through two modes the user can decide to exercise body or mind while being transported. This is done by the usage of mixed realities which connects and relates with the passing surrounds. The project hereby links the digital world with the real one, in order to create new notions of what a travel experience could be in the future.

This thesis explores how planners can facilitate children’s wellbeing through auditing the urban environment for active travel. The findings reveal that audits have the potential to address critical issues regarding the quality of the built environment around schools. Further, children were found to be effective evaluators of their school environment. Auditing can be improved by highlighting the sensory qualities of the built environment and using audits strategically to adapt to the policy context of school environments.

Full textAbstract:
Site-directed mutagenesis in recombinant soybean ascorbate peroxidase (rsAPX) has been performed to probe structure/function relationships in this and other heme proteins. In Chapter Two, we present mechanistic, spectroscopic, and structural evidence for peroxide- and ligand-induced conformational mobility of the distal histidine (His-42) in the W41A variant of ascorbate peroxidase. In this variant, His-42 binds “on” to the heme in the oxidised form, duplicating the active site structure of the cytochromes b but, in contrast to cytochromes b, is able to swing “off” the iron during catalysis. Contrary to the widely adopted view of heme enzyme catalysis, these data indicate that strong coordination of the distal histidine to the heme iron does not automatically undermine catalytic activity. In Chapter Three, we have shown that conformational rearrangement in W41A, discussed above, can also be triggered upon reduction of the heme iron. We present structural, spectroscopic and ligand binding data that support dissociation of His-42 from the iron in the ferrous form of W41A. Structural studies provide evidence for formation of a reduced, bis-histidine-ligated species that subsequently decays by dissociation of His-42 from the heme. Collectively, the data provide clear evidence that conformational movement within the same heme active site can be controlled by both ligand binding and metal oxidation state. In Chapter Four, we present evidence for heme oxygenase reactivity in the W41A variant of rsAPX. Crystallographic, spectroscopic, HPLC and MS techniques reveal that the heme is modified on reaction of W41A with tert-butyl hydroperoxide to yield a tert-butyl derivative of biliverdin. Evidence for formation of a hydroperoxo, Compound 0, intermediate is also presented. A common intermediate for the two heme enzymes is proposed. In Chapter Five, we examined the affect of disruption of the conserved distal histidine-asparagine hydrogen bond on active site mobility by formation of a series of asparagine-71 (Asn-71) variants. The spectroscopic data presented provide clear evidence that the conserved distal histidine-asparagine bond is required to maintain the correct orientation of distal histidine in the active site of rsAPX.

Full textAbstract:
L’objectif de ce travail est de déterminer l’influence des réductions de mobilité ostéo-articulaire passive et active sur la capacité posturo-cinétique. La réduction de mobilité passive est analysée à travers un mouvement d’élévation des membres supérieurs à vitesse maximale au cours duquel seront mesurés des indices électromyographiques (Tibial antérieur, Soléaire) et biomécaniques (plateforme de force, accéléromètre). La réduction de mobilité active est étudiée à partir d’un examen posturographique combiné à un mouvement de compression d’une barre dynamométrique et à l’enregistrement de la cinématique respiratoire. L’analyse de la composante passive révèle que, dès 50% de perte de mobilité au niveau de la région cervicale, la capacité posturo-cinétique (CPC) est perturbée. Le blocage passif des articulations des chevilles et du rachis cervical semble davantage réduire la CPC que celui des genoux ou du rachis lombaire. L’étude de la composante active montre que l'augmentation de la tension musculaire active le long du tronc est susceptible de perturber l'équilibre postural, mais uniquement lorsqu'elle dépasse un certain niveau. Ainsi les deux composantes, passive et active, de la mobilité ostéo-articulaire, paraissent chacune jouer un rôle dans la capacité à compenser les perturbations associées au maintien postural ou à l’exécution du mouvement<br>The aim of this study was to determine the influence of passive and active components of osteoarticular mobility on the capacity posturo-kinetic. The passive component was analyzed through a paradigm of upper limb elevation at maximum velocity, during which electromyographic (Tibialis anterior, soleus) and biomechanical (force platform, accelerometer) parameters were measured. The active component was studied from an experimental paradigm associating a posturaphic examination with a bimanual compression of a dynamometric bar. Results analysis showed that the posturo-kinetic capacity (PKC) was reduced when the loss of mobility exceeded 50% at the neck level. Passively blocking the ankle joints and the cervical spine seemed more likely to reduce the PKC than blocking the knee or the lumbar spine. The study of the active component showed that the increase in active muscle tension along the trunk may impair body balance, but only when it exceeds a certain level. Thus the two components, passive and active, of the osteoarticular mobility, appeared as significant factors in the ability to compensate for the disturbances associated with postural maintenance or movement execution

Glavey, Russell. "The geometric stochastic resonance and rectification of active particles." Thesis, Loughborough University, 2015. https://dspace.lboro.ac.uk/2134/18473.
Full textAbstract:
This thesis describes the work of three research projects, the background research that motivated the work, and the resultant project findings. The three projects concerned: (i) Geometric stochastic resonance in a double cavity, (ii) Synchronisation of geometric stochastic resonance by a bi-harmonic drive, and (iii) Rectification of Brownian particles with oscillating radii in asymmetric corrugated channels. In the project 'Geometric stochastic resonance in a double cavity', we investigated synchronisation processes for the geometric stochastic resonance of particles diffusing across a porous membrane and subject to a periodic driving force. Non-interacting particle currents were driven through a symmetric membrane pore either parallel or perpendicular to the membrane. Then, harmonic mixing spectral current components were generated by the combined action of parallel and perpendicular drives. The role of the repulsive interaction of particles as a controlling factor with potential applications to the transport of colloids and biological molecules through narrow pores was also investigated. In 'Synchronisation of geometric stochastic resonance by a bi-harmonic drive', we simulated the stochastic dynamics of an elliptical particle using the Langevin equation. The particle was simultaneously driven by low and high frequency harmonic drives across a porous inter-cavity membrane. It was observed that the particle oscillated out of phase with the low frequency drive. This effect was due to the absolute negative mobility the particle would have exhibited if the low frequency drive had been replaced by a dc static force. It was also observed that the magnitude of this out-of-phase stochastic resonance depends on how the combined action of the driving forces and noise fluctuations affect the particle orientation, and as such was shown to be sensitive to the particle shape. This emphasises the importance of particle geometry, in addition to chamber geometry, to the realisation and optimisation of geometric stochastic resonance. In the project 'Rectification of Brownian particles with oscillating radii in asymmetric corrugated channels', we simulated the transport of a Brownian particle with an oscillating radius freely diffusing in an asymmetric corrugated channel over a range of driving forces for a series of temperatures and angular frequencies of radial oscillation. It was observed that there was a strong influence of self-oscillation frequency upon the average particle velocity. This effect can be used to control rectification of biologically active particles as well as for their separation according to their activity, for instance in the separation of living and dead cells. The background research is described in Chapter One and the research findings are described along with their related projects in Chapters Two and Three.

As farmers continue to get older, they will likely face age-related disabilities that impede their ability to work and increase risk of suffering serious injuries. One of the major age- related diseases is arthritis, which currently accounts for about 40% of disability cases in agriculture nationwide. The effect of arthritis on farmers is profound because it reduces their physical strength, joint range of motion and is a source of joint pain, all culminating in the lack of ability to perform routine activities regularly and safely. One way to decrease the rate of injuries is by reducing the strength and joint loading required to perform these activities through the use of wearable robotics. As opposed to existing solutions that focus only on injury prevention, this thesis will present an active, knee-assist exoskeleton intent on providing 30% of the necessary joint rotation force to perform activities such as sit-to- stand actions and the ascent/descent of stairs and hills. The device will be a lightweight, unobtrusive cable-driven exoskeleton actuated by distally-worn electric motors. We hope that use of the exoskeleton will result in increased ranges of motion and overall reduction of stress on the wearer's body, which will minimize the effects of arthritis and ultimately improve safety and quality of life.<br>Master of Science<br>As farmers continue to get older, they will likely face age-related disabilities that impede their ability to work and increase risk of suffering serious injuries.

Full textAbstract:
In countries such as Australia, children's active and independent mobility has declined in the past 40 years, with less children walking to school. As physical activity is a key component of child health and well-being this decrease in children’s independent mobility (CIM) and active travel (AT) has placed children at greater risk of physical and mental health problems. To confront this problem, travel behaviour change interventions to promote active and independent school travel are currently deployed in Australia by local and state governments. To date there have been few comprehensive studies of these interventions and in particular, whether and how they relate to contemporary parental attitudes and perceptions about CIM. There remain significant research gaps about the relative importance of travel behaviour change programs in parental decision-making processes.
As part of the larger iMATCH (independent Mobility, Active Travel and Children’s Health) Project this research sought to identify the range of current interventions being used in Australia, the attitudes and perceptions of parents and guardians in a range of urban environments across the country, and to explore how interventions may better respond to these concerns to increase their effectiveness. A theoretical framework based on Azjen’s (1988) Theory of Planned Behaviour (TPB) and the Trans- theoretical model of behaviour change (TTM) was developed to guide the research. The suggested theoretical model was examined by adopting the structural equation modelling (SEM). The valid and
reliable model was introduced regarding evaluating, designing, and running travel behaviour change interventions. This model was employed as a fundamental structure for guiling the research process.
Interventions used in Australia were examined firstly using published project evaluations, websites and other reports, with attention given to their treatment of CIM and their efficacy. The broader iMATCH study used child and parent surveys and travel diaries, amongst other methods, collected from schools in nine neighbourhoods in Perth, Melbourne, Brisbane and Rockhampton. Responses provided in 309 parent surveys were examined in detail. A total of nine parents from two schools in Brisbane and one in Ipswich that were part of the broader study were then recruited for either a focus group discussion or a face-to-face interview, eliciting further detail on their attitudes.<br>Thesis (PhD Doctorate)<br>Doctor of Philosophy (PhD)<br>Griffith School of Environment<br>Science, Environment, Engineering and Technology<br>Full Text

Full textAbstract:
Photopolymerization is considered an attractive alternative in many industries to traditional polymerization processes. The advantages of photopolymerization over other types of polymerization include elimination of heat sources, faster cure times, and reduction in the use of volatile organic solvents. Despite these environmental and cost-saving advantages, photopolymerizations have several limitations. Light attenuation can be a problem for systems containing pigments or fillers. The radiation source penetrates only to a shallow depth beneath the surface, limiting the thickness of strongly pigmented or filled coatings and films. Photopolymerization is also generally limited to systems with simple geometries that can be uniformly illuminated. Coatings on three-dimensional substrates, or other systems with complex geometries, are difficult to uniformly cure. These problems can be solved by "shadow cure," which is defined as the reactive diffusion of photoinitiated active centers into regions of a polymer that are unilluminated. In this contribution, the generation and subsequent spatial and temporal evolution of the active center concentrations during illumination are analyzed using the differential equations that govern the light intensity gradient and photoinitiator concentration gradient for polychromatic illumination. Reactive diffusion of the active centers during the post-illumination period is shown to result in cure of unilluminated regions. A kinetic analysis is performed by coupling the active center concentration profiles with the propagation rate equation, yielding predicted cure times for a variety of applications. This analysis is used for the evaluation of cationic shadow cure in pigmented photopolymerization systems, and systems with complex geometries. The extensive characterization of cationic systems is then applied to free-radical photopolymerization to examine the potential of shadow cure for active centers with much shorter lifetimes. An example of a free-radical photopolymerization system is characterized in which the dimensional scales are small enough to utilize the short lifetimes of the active centers. The results presented for both free-radical and cationic shadow cure indicate that the reactive diffusion of photoinitiated active centers may be used for effective cure in unilluminated regions of a photopolymer. This research will potentially allow photopolymerization to be applied in industries where it has never before been utilized.

Population ageing is one of the major challenges of the 21st century and societies need to optimize opportunities for active ageing. This thesis explored how the built environment impacts the mobility and participation within the community. A combination of person-based GPS tracking and in-depth interviews was used to collect data on transportation use and engagement in activities of older people living within Brisbane. It showed that the built environment has a strong impact on mobility. To enable healthy and active ageing modern communities need to overcome car dependency and provide mobility options that are tailored towards older people’s needs.

Full textAbstract:
Liquid chromatography coupled with mass spectrometry (LC-MS) and tandem mass spectrometry (LC-MS2) are shown to have the sensitivity and functionality to detect protein/peptide modifications by fatty acyl chains in vitro and in vivo studies. Further analysis was also performed by direct infusion ion mobility separation coupled with mass spectrometry (IMS-MS) or tandem mass spectrometry (IMS-MS2). Peptide lipidation in vitro was investigated using the membrane active peptide, melittin. Non-enzymatic melittin lipidation by lysophospholipids has been observed for the first time. When the effect of lysophospholipids was studied in direct competition with diacylphospholipids, the acyl transfer from the lysophospholipids is seen to be preferential with acylation visible after just 3 hour. The longer the interaction time, the greater the amount and number of modifications with double and triple acylation observed after 96 hour. The locations of the modifications identified through LC-MS2 were assigned on different sites of the peptide, including N-terminus, K7, S18, K21, K23, R22 and R24 and with the highest reactivity towards N-terminus and K23. Comparing the lipidation of synthetic melittin (SynM) with the lipidation of naturally occurring melittin from venom of honey bee (BVM) highlights the effect of the PLA2 enzyme that is naturally present in BVM. Here, the action of the enzyme to hydrolyse the diacylphospholipid at the sn-2 position to give the corresponding lysophospholipid is reflected in the acyl transfer to the BVM such that the resulting lysophospholipid clearly dominates the acyl transfer to BVM. In contrast, the acyl transfer to SynM clearly demonstrates that acyl transfer is possible in the absence of an enzyme. In vivo protein lipidation of one of the most abundant integral membrane proteins in mammalian eye lens, AQP0, was also studied. A wide range of acyl groups are shown to modify this protein at the known modification sites, N-terminus and at the amino acid residue K238, many of which are reported here for the first time. These acyl group modifications reflect the biological lipid composition of the membrane leaflet that the acylation sites are proximal to. In an attempt to further distinguish between different forms of lipidated melittin, whether with the same acyl chain modification to different amino acids or to discriminate between palmitoylation and oleoylation modifications, travelling wave ion mobility spectrometry (TWIMS) coupled with MS or MS2 was applied. Results suggested that resolving positional isomers of diacylphospholipids and lysophospholipids (sn-1 vs sn-2 positions) is not possible under the conditions described herein. However, the presence of fatty acyl chains covalently bound to melittin change the conformation of acylated melittin in the gas-phase such that for lower charge states it is possible to suggest a small degree of separation between palmitoylated and oleoylated melittin or their isomers including acylation on N-terminus vs K23. This small degree of separation is enough so that when combined with tandem mass spectrometry, the time-aligned product ion spectra are clearer and improve characterisation. To conclude, the research in this thesis has shown that two of the most abundant biomolecules, lipid and peptides/proteins that are known to exist in close proximity to each other, or interact with each other, are not as chemically inert as previously thought. This reactivity has been reflected herein via aminolysis reaction between membrane lipid composition and each of membrane active peptide, melittin and integral membrane protein, AQP0.

Full textAbstract:
Environmental changes significantly impact health behavior. Active travel behavior is mostly affected by increasing motorization, urban sprawl, and traffic safety. Especially for children, active and independent travel can contribute to physical activity, social and motor development, and other health-related outcomes. A reduced number of children engaging in independent mobility over the last 20 years demanded researchers to further examine the construct of children’s independent mobility. By examining relevant literature, this narrative review aims to provide the current state of knowledge on children’s independent mobility, and identify future directions in research, as well as practical implications. From a public health perspective, considering children’s independent mobility in intervention programs is recommended, since it is associated with numerous health and environmental benefits. To develop interventions, multilevel socio-ecological influences on children’s independent mobility are widely examined; however, evidence is limited due to heterogeneous measurements and a lack of high-quality prospective studies. To oppose the decline in children’s independent mobility, further analysis using comparable measures is needed to understand the determinants of children’s independent mobility and to enable international comparison.

Full textAbstract:
This research in the field of transport sociology explores how workplaces in Stockholm can become actors in managing transport demand and through soft measures contribute to an increase of sustainable and active commuting to work and short-distance travel on work purposes. It uses a mixed-method approach consisting of a review of official documents, publications and initiatives, a web-survey and semi-structured interviews with representatives of Stockholm’s public and private workplaces. The study uncovers the current role of workplaces in mobility management policies of Stockholm, analyzes internal and external factors that influence the likelihood of workplaces to encourage sustainable and active commute and travel to meetings within the city among their employees and provides recommendations on how workplaces engagement can be increased. Being occasionally mentioned in the policy documents or invited to take part in climate or cycling-focused initiatives, workplaces in Stockholm are now at different stages in their willingness to have travel policies and participate in on-site mobility management. Internal and external factors influence the motivation of public and private, larger and smaller workplaces differently. With further research, comprehensive communication, questioning the status quo and establishing a constant dialogue between the city and workplaces there is a big potential to involve workplaces as new actors into various existing initiatives.

Promover a segurança viária no entorno escolar é uma estratégia que contribui para que sejam construídas cidades seguras, saudáveis e sustentáveis. Nesse sentido, este estudo é dedicado a identificar a influência das características da estrutura urbana na frequência e na severidade dos acidentes no entorno de escolas de educação básica de Porto Alegre. A análise da frequência e da severidade de acidentes foi conduzida através da estimação de modelos econométricos: binomial negativo e logit ordenado, respectivamente. Para esses, foram calculados os efeitos marginais, permitindo a observação da magnitude dos impactos das variáveis explicativas sobre as variáveis dependentes. As variáveis dependentes frequência e severidade foram extraídas dos acidentes registrados em Porto Alegre entre 2012 e 2014. Foram incluídas, simultaneamente, variáveis da estrutura urbana, das escolas, socioeconômicas e dos acidentes (para a severidade). A partir do geoprocessamento dos dados existentes, os entornos escolares puderam ser caracterizados para três diferentes áreas circulares de análise (buffer ring) de raios de 100, 150 e 200 metros, permitindo a comparação do uso das diferentes áreas. O conjunto de estimativas indica que áreas menores produzem modelos de melhor desempenho para ambas as técnicas empregadas. No entanto, áreas maiores permitem a análise de maior quantidade de variáveis relativas à estrutura urbana. Essa relação sugere os benefícios da escolha a partir do trade-off entre ajuste do modelo e sua capacidade de propiciar análises de variáveis. Foi identificado que a frequência e a severidade de acidentes podem estar relacionadas a uma única variável explicativa de formas opostas – a partir de sinais contrários. Essa diferença de resultados para frequência e severidade de acidentes indica que há maiores benefícios em analisá-las em conjunto. Identificou-se ainda que existem benefícios para a segurança viária em áreas de estrutura urbana com quarteirões menores e maior quantidade de interseções de quatro vias, em frequência e severidade, respectivamente. Já as áreas mais arborizadas tendem a apresentar acidentes de menor severidade nos casos de usuários de modos ativos.<br>Fostering road safety nearby schools is a strategy that contributes to build safe, healthy and sustainable cities. The aim of this study is to identify the influence of the built environment characteristics in the frequency and severity of accidents nearby elementary and secondary schools in Porto Alegre. The frequency and severity of the accidents were analyzed using econometric models: negative binomial and ordered logit, respectively. The evaluation of their marginal effects allowed the magnitude of the impact caused by the explanatory variable on the dependent variables to be observed. The measured variables frequency and severity were extracted from accidents registered in Porto Alegre from 2012 and 2014. Built environment, socioeconomic and school variables were also included, as well as accident data (for severity). Data geoprocessing allowed school surroundings to be characterized for three different buffer rings, measuring 100, 150 and 200 meters of radius. Thereby it was possible to compare the inclusion of different areas in the study. The estimations indicates that models based on smaller areas have better performances for both employed techniques, whereas larger areas allow the study of a bigger quantity of urban infrastructure variables. That indicates the benefits of choosing based on a trade-off between model adjustment and capacity to engender the analysis of variables. It was shown that frequency and severity of accidents could be related to a single explanatory variable in opposite ways – based on contrary signs. This difference in the results found for frequency and severity indicates that there are more benefits when analyzing them together. Moreover, there are benefits for road safety in areas where the city blocks are shorter and where there are more four-way intersections, in frequency and severity of accidents, respectively. Also, areas of more important afforestation tend to decrease the severity of accidents involving users of active modes.

Dissertação de Mestrado Integrado em Arquitetura, com a especialização em Arquitetura apresentada na Faculdade de Arquitetura da Universidade de Lisboa para obtenção do grau de Mestre.<br>A relação do homem com a cidade transcende os aspectos considerados no planejamento urbano do século XX e apresenta características subjetivas na sua identificação com o espaço público, indispensáveis para o bem-estar social. Propõe-se uma revisão teórica acerca da origem do Urbanismo em suas diversas correntes utópicas que influenciaram o meio urbano conhecido hoje, buscando compreender formas mais humanas de se intervir na cidade. A necessidade do lugar, enquanto suporte existencial do ser, é exposta através da manifestação social, onde a rua assume caráter decisivo na escala da urbe, originando movimentos como o Placemaking. Entende-se a influência do ambiente construído no comportamento humano, e destacam-se as qualidades perceptivas do desenho urbano que, apesar de subjetivas, tem relação com atributos físicos, sendo, portanto, papel do arquiteto compreende-las e geri-las. A mobilidade urbana é um dos principais temas que relacionam o homem com o meio, sendo a integração com os modos ativos a forma mais eficaz de se alcançar comunidades sustentáveis. Assim, explora-se a Caminhabilidade enquanto ferramenta benéfica para a sociedade nos aspectos econômicos, ambientais, de saúde (física e mental) e, principalmente, sociais. A componente prática consiste em aplicar um modelo de análise qualitativa do ambiente urbano, e compará-lo com as análises quantitativas nos diferentes casos de estudo no concelho de Cascais. Com os resultados faz-se uma reflexão sobre como, a partir do impacto das qualidades perceptivas na mobilidade ativa, é possível promover ruas mais propícias às atividades não necessárias, ou seja, as atividades opcionais e sociais.<br>ABSTRACT: The relationship between man and the city exceeds the aspects considered in the urban planning of the twentieth century and presents subjective characteristics in its identification with the public space, essential for social well-being. This study proposes a theoretical overview of the birth of various utopian trends that influenced the urban environment known today in Urbanism, seeking to understand more human ways of intervening in the city. The place, as existential support, is exposed through social expression, where the street assumes the decisive character in the scale of the city, emerging movements like Placemaking. The document shows the influence of built environment on human behavior, focused on the perceptual qualities in urban design. Its subjectiveness is related to its physical attributes, and it is the architect responsibility to understand and manage them. Urban Mobility is one of the main topics that shows the relationship between man and the environment, making the active mode integration the most effective way to achieve sustainable communities. Therefore, it discusses the walkability as a positive tool to society’s issues such as economic, ecological, human health, and social. The validation is to apply a qualitative and quantitative analysis model to the urban environment and compare them, within the several study cases from Cascais, Portugal. As a result, it is possible to understand the impact of the perceptual qualities in active mobility, and its influence on promoting more livable streets with non-necessary activities, such as optional and social.<br>N/A

Full textAbstract:
In recent years, the need for personal urban mobility has increased a lot especially in emerging and developing countries. It becomes increasingly important to explore propulsion systems that use alternative energy sources and are related to the chain of production, storage and use of renewable energy. Several studies have been conducted in this area, but very few have achieved solutions for the interaction of the vehicle with the building by which it is parked in terms of a multi-energy exchange. Technological innovation of house plant parts, of large residences / hotels, of shelter stations for vehicles, it is now crucial to implement the integration of more renewable energy sources within the same building structure: this is one of the aspects covered by the most general definition of "Smart Housing". Sustainable mobility is perceived as a strong need to match individual urban and sub-urban mobility, to the least environmental and social impact of such personal need.
This research project proposes a possible scenario for energy integration between smart housing and smart mobility using a common energy platform that allows self-generation, storage and energy exchange between residential district buildings and smart vehicles. The project integrates multidisciplinary approaches with the aim of designing, evaluating technical and industrial feasibility for the development of: 1) Modular and scalable energy storage devices dedicated to a smart house. 2) a modular city vehicle, with high flexibility of use, with energy storage system and energy-efficient switching capabilities with smart building.

No Brasil e em São Paulo as políticas públicas de mobilidade urbana foram historicamente orientadas para promover a fluidez dos automóveis. A partir do século XXI, particularmente na segunda década, o debate sobre mobilidade se desloca, passando a focar nas pessoas, ao invés de veículos, e na promoção de modos ativos. Esta pesquisa se insere neste contexto, analisando o instrumento de controle de impacto no sistema de circulação urbana denominado Polos Geradores de Tráfego. A partir de novos conceitos referenciais para mobilidade urbana, discutimos a evolução do marco regulatório referencial para este instrumento. Analisamos, então, como ele tem sido aplicado pela Companhia de Engenharia de Tráfego através de uma ampla amostra desses empreendimentos e do estudo de caso comparativo entre dois shopping centers em São Paulo. Os resultados indicam que o instrumento tratado aqui e sua aplicação apresentam baixa aderência às condições territoriais, levando a uma abordagem limitada dos elementos de produção e atração de viagens. Com esta pesquisa, esperamos contribuir para o debate atual sobre a produção de cidades mais sustentáveis e mais acessíveis espacial e socialmente.<br>In Brazil and in São Paulo, the public policies concerning urban mobility have been historically oriented to promote the traffic flow for automobile. On the beginning of the XXI century, and particularly on its second decade, the debate about mobility started to a focus on people, rather than vehicles, and on the promotion of active modes. In this context, this research analysis the instrument used to control the impact on the circulation system, entitled Traffic Generating Poles. Based on new references for mobility policies we discuss the evolution of the regulatory framework for this instrument. We analyze how it has been implemented by the Traffic Engineering Company through a large sample of these buildings and a case study comparing two shopping centers in São Paulo. The results indicate that the instrument and its implementation present a low adherence to the conditions of the territory, leading to a limited approach on the elements of production and attraction of trips. With this research, we hope to contribute to the current debate on the production of cities that are more accessible both spatially and socially, and more environmentally friendly.

O objetivo deste estudo foi elaborar uma estratégia para avaliação da resiliência na mobilidade urbana, focando-se na restrição ao transporte motorizado. Assim, assumiu-se hipoteticamente que as viagens poderiam ser feitas apenas a pé ou de bicicleta. As viagens foram classificadas como persistentes, adaptáveis e transformáveis. As viagens persistentes e adaptáveis foram consideradas resilientes, enquanto as viagens transformáveis foram consideradas vulneráveis. Uma nova segmentação precisou ser criada para este trabalho: a excepcionalidade, que engloba viagens por modo a pé ou bicicleta além dos limites das Distâncias Máximas Possíveis (DMP). Os estudos de caso foram feitos na cidade de São Carlos e em um conjunto de três municípios da Região Metropolitana de Maceió (RMM): Maceió, Rio Largo e Satuba. No estudo em São Carlos, o pior cenário teve 40,4% de resiliência, e atingiu 100% com 11 km de DMP de bicicleta. Na RMM, o cenário mais pessimista apresentou uma resiliência de 43,0%, e atingiu o seu máximo aos 28 km. Os resultados também revelaram diferentes padrões espaciais de viagens para cada condição da resiliência. Em São Carlos, viagens persistentes apresentaram um padrão pontual. Viagens adaptáveis mostraram um padrão radial. As viagens transformáveis exibiam um padrão mais diametral, de um extremo ao outro da cidade. A análise por zona mostrou que as viagens transformáveis têm maior frequência em zonas afastadas do centro da cidade. Em RMM, os padrões encontrados foram semelhantes. As viagens persistentes, por exemplo, também eram predominantemente intrazonais. Além disso, as viagens adaptáveis tornaram-se mais concentradas em partes específicas da área urbanizada (por exemplo, ao norte da região), a medida que os valores de DMP aumentaram. O trabalho mostra a necessidade da adoção de políticas de incentivo aos modos ativos de transporte, no intuito de diminuir a dependência da sociedade de veículos motorizados.<br>The objective of this study was the development of a strategy to evaluate how urban mobility resilience would be affected by constraints imposed to motorized transport modes. The analysis was based on the hypothetical assumption that only walking and cycling trips would be possible. The trips were initially classified as persistent, adaptable and transformable. Trips in the first two groups were considered resilient trips, whereas the trips in the third group were vulnerable trips. A fourth category was created to accommodate walking and cycling trips that went beyond the Maximum Distances (MD) per mode that were also defined as part of the method. Case studies were conducted in the city of São Carlos and in Maceió Metropolitan Region (MMR), which contains three municipalities: Maceió, Rio Largo and Satuba. In the case of São Carlos, we found a resilience value of 40.4% in the worst scenario. Resilience values would increase for larger MD values, reaching a maximum resilience of 100% for a MD of 11 km. In MMR, the minimum resilience value found was 43.0%, and the maximum resilience value corresponded to a MD of 28 km. The results also indicated different spatial patterns for each group of trips. In São Carlos, persistent trips were mainly intrazonal trips, adaptable trips had a radial pattern, and transformable trips crossed the urban area. The analysis per zone have shown a concentration of transformable trips in zones far from the city center. In MMR, the patterns were similar. Persistent trips, for example, were also mostly intrazonal trips. In addition, adaptable trips became more concentrated in specific parts of the urbanized area (e.g. the northern part of the region) as MD values increased. This study indicate the need for policies that encourage the use of active modes of transportation, in order to decrease the dependence of society in motorized vehicles.

L'objectif de cette thèse est de mettre en perspective les approches nationales de la formation et de l'emploi des jeunes par une comparaison du système d'enseignement supérieur et de la transition professionnelle des étudiants en France et en Corée du Sud. Les contextes éducatifs des deux pays montrent certaines caractéristiques communes concernant la hiérarchie scolaire des filières et l'influence du diplôme sur le premier emploi, tandis qu'il existe des différences en matière d'accès à l'enseignement supérieur : le modèle français caractérisé par la spécialisation précoce, et le modèle coréen représenté par l'examen standardisé. Dans ce contexte, nous avons mené une étude qualitative pour comprendre le rôle des stages des étudiants dans leurs choix d'orientation et leurs identités professionnelles, ainsi que la relation implicite de ce processus avec le déterminisme social ou les opportunités de choix par l'éducation. Notre recherche empirique a adopté une méthode biographique décrivant des récits d'expérience de stage à partir d'entretiens semi-directifs menés avec 21 étudiants français et coréens. Selon les résultats de l'analyse, la satisfaction des étudiants en stage et leurs perspectives sur les trajectoires professionnelles sont étroitement liées à leur parcours scolaire dans les deux pays comparés. En revanche, les étudiants français et les étudiants coréens montrent des attitudes différentes à l'égard des choix professionnels et des processus psychosociaux qui constituent leurs projets professionnels. En mettant en évidence la réalité et les choix des étudiants par rapport à la question d’être et de faire dans leur vie active, notre analyse propose que l'enseignement supérieur doit s’intéresser davantage aux compétences transférables et aux capacités d'adaptation des étudiants dans le marché du travail en évolution rapide, sans les restreindre à des systèmes éducatifs rigides et à des fonctions fixes<br>The aim of this thesis is to put into perspective the national approaches to youth employment and training by comparing the higher education system and the professional transition of students in France and South Korea. The educational contexts of the two countries show certain common characteristics concerning the educational hierarchy of the study program and the influence of the degree on the first job, while there are differences in terms of access to higher education : the French education system characterized by early specialization, and the Korean education system represented by the standardized tests. In this context, we conducted a qualitative study to understand the role of student internships in their career choices and professional identities, as well as the implicit relationship of this process with social determinism or opportunities for choice through education. Our empirical research adopted a biographical method describing internship experiences from semi-structured interviews conducted with 21 French and Korean students. According to the results of analysis, students' satisfaction with their internship and their perspective for professional career paths are closely linked to their educational path in the two countries compared. On the other hand, French students and Korean students show different attitudes towards professional choices and psychosocial processes that constitute their professional projects. By highlighting the reality and the choices of students in relation to the question of being and doing in their working life, our analysis suggests that higher education needs to focus more on the transferable skills and adaptability of students in the rapidly changing labor market, without restricting them to rigid education systems and fixed functions

Full textAbstract:
Les questions de mobilité et de logement sont aujourd'hui au centre des enjeux du développement urbain. La hausse du taux de motorisation, de la pression sur le marché du logement, poussent à une déstructuration des liens de proximité et génèrent aujourd'hui une saturation du système de transport. De cette difficulté à se déplacer naissent des tensions (augmentation du temps de trajet, risque de retard, etc.). L'objectif de cette thèse est alors d'étudier le poids de ces tensions dans la décision de déménager. Une enquête a été réalisée auprès de 500 résidants actifs luxembourgeois ayant déménagé sans changer de lieu de travail. Les résultats montrent que certains individus se sont bien rapprochés de leur lieu de travail dans le but de réduire ces tensions. Cette recherche a donc permis de mettre en évidence des liens de conjonction entre la mobilité quotidienne et résidentielle et d'aboutir à une meilleure compréhension du système de la mobilité spatiale locale des individus.

La majoria dels països del món estan experimentant una de les majors transformacions socials d'aquest segle: l'envelliment de la població. En aquest context, la vellesa com a etapa de la vida es caracteritza per diversos canvis físics i socials que poden reduir la capacitat d'una persona per desplaçar-se. Això genera aïllament i perduda d'independència per realitzar les seves activitats quotidianes, resultats que incideixen en la qualitat de vida i benestar d'aquest grup de la població. Per tant, mantenir un estil de vida actiu durant aquesta etapa de la vida és una alternativa per fer front a aquestes problemàtiques. El desplaçament a peu emergeix com una opció de transport actiu que atorga diversos beneficis als adults majors per mantenir-se actius i independents.
La majoria dels desplaçaments a peu de la gent gran es realitzen al barri, per la qual cosa el disseny i els diversos elements que interactuen en aquest espai de proximitat són factors que determinen els seus desplaçaments. En aquest context els barris caminables, són l'opció de disseny que més s'adapta a les necessitats dels adults grans. Principalment perquè estan dissenyats a l'escala de l'vianant.
Per tant, aquesta tesi planteja, que per a la gent gran caminar és una activitat que té múltiples significats i beneficis, que generen una experiència de mobilitat que està determinada per elements subjectius com la percepció de barri on viuen. Per aconseguir-ho, s'han integrat, una metodologia quantitativa a una de caràcter qualitatiu, així com l'ús de Sistemes de Posicionament Global (GPS) i d'acceleròmetres que permeten la triangulació de diverses fonts d'informació. Els resultats d'aquesta tesi poden informar futures actuacions de planificació urbana que integrin les necessitats de mobilitat quotidiana dels adults grans.<br>La mayoría de los países del mundo están experimentando una de las mayores transformaciones sociales de este siglo: el envejecimiento de la población.

Esto genera aislamiento y perdida de independencia para realizar sus actividades cotidianas, resultados que inciden en la calidad de vida y bienestar de este grupo de la población. Por lo tanto, mantener un estilo de vida activo durante esta etapa de la vida es una alternativa para hacer frente a estas problemáticas. El desplazamiento a pie emerge como una opción de transporte activo que otorga diversos beneficios a los adultos mayores para mantenerse activos e independientes.
La mayoría de los desplazamientos a pie de las personas mayores se realizan en el barrio, por lo cual el diseño y los diversos elementos que interactúan en este espacio de proximidad son factores que determinan sus desplazamientos.

Por lo tanto, esta tesis plantea, que para las personas mayores caminar es una actividad que tiene múltiples significados y beneficios, que generan una experiencia de movilidad que está determinada por elementos subjetivos como la percepción del barrio donde viven. Para conseguirlo, se han integrado, una metodología cuantitativa a una de carácter cualitativo, así como el uso de Sistemas de Posicionamiento Global (GPS) y de acelerómetros que permiten la triangulación de diversas fuentes de información. Los resultados de esta tesis pueden informar futuras actuaciones de planificación urbana que integren las necesidades de movilidad cotidiana de los adultos mayores.<br>Most countries in the world are experiencing one of the greatest social transformations of this century: demographic ageing. In this context, old age as a stage of life is characterized by various physical and social challenges that can reduce a person's ability to move. This can generate isolation and loss of independence when carrying out daily activities and, in turn, affect the quality of life and well-being of this segment of the population. Consequently, maintaining an active lifestyle during this stage of life is an alternative when it comes to addressing these problems. In this context, walking emerges as an active transport mode that helps elderly people to stay active and independent.
Most of the walking trips that the elderly make occur in the neighbourhood so the design and the various elements that interact in this proximity space are factors that determine their walking experience. In this context, walkable neighbourhoods emerge as the most suitable design option when it comes to the needs of elderly people.
This thesis proposes that walking is an activity that has multiple meanings and benefits for the elderly and generates a mobility experience that is determined by subjective elements such as the perception of the neighbourhood where they live. To this end, this thesis incorporates both a quantitative methodology and a qualitative one, as well as the use of Global Positioning Systems (GPS) and accelerometers that allow triangulation of various sources of information to be integrated in the analysis. The results of this thesis can inform future urban planning actions that integrate elderly mobility needs when designing neighbourhoods.

L’action collective urbaine est confrontée à une double injonction potentiellement contradictoire en matière de mobilité quotidienne. Elle doit garantir l’accès à la mobilité pour tous et réduire les mobilités individuelles motorisées. Avec la pluralisation des politiques urbaines, cet enjeu de cohérence se double d’un enjeu de coordination, qui subsume la traditionnelle cohérence urbanisme-transport.Cette thèse interroge la conciliation des enjeux d’accès à la mobilité et de mobilité durable. L’étude analyse la prise en compte des inégalités d’accès à la mobilité dans les politiques urbaines de la Communauté Urbaine de Lyon. Les aides à la mobilité des politiques de retour à l’emploi et les Plans de déplacement inter-entreprises portés par la politique temporelle, sont comparés à la tarification sociale et l’amélioration de la desserte des quartiers défavorisés de la politique de transport.Les résultats montrent que les enjeux sociaux n’ont jamais fait l’objet d’une attention aussi grande, avec le passage d’un droit au transport pour tous à un droit au transport ciblé et l’émergence de droits à la mobilité. Mais, la conciliation entre les enjeux potentiellement contradictoires d’accès à la mobilité pour tous et de mobilité durable est difficile à l’échelle d’agglomération, ces enjeux étant concurrents lorsque sont arbitrés les choix politiques et financiers. La prise en compte des enjeux sociaux est retardée, limitée, voire oubliée en cours de route, la stratégie d’agglomération étant orientée vers l’attractivité économique et l’exemplarité en matière de développement durable<br>Urban policies have to conciliate the paradoxical stakes that are access to mobility for everyone on one hand and personal car use reduction on the other hand. Considering the pluralisation of urban policies, this issue is not only a matter of coherence but also of coordination that subsumes the coordination of land-use planning and transport.This study examines how urban policies conciliate access to mobility and sustainable mobility. It analyzes how urban policies take into account access to mobility inequalities in the Greater Lyon. Innovative mobility services (access to work initiatives and Inter-Companies Commuter Plans) are compared with transport policies.The unprecedented focus on social issues results of the shift from a right to transport to a targeted right to transport and the joint emergence of rights to mobility. But, since they are competing when political and financial choices are arbitrated, conciliating these potentially contradictory issues is difficult at the local urban scale. Social issues are taken into account with delay or limited or forgotten with the Greater Lyon’ strategies being concentrated on economic competitiveness and sustainable development exemplarity

Doutoramento em Economia<br>Recentemente, foram introduzidas em Portugal diversas reformas estruturais no sistema de protecção social com impacto nas decisões ocupacionais dos indivíduos. A análise procurará contribuir para o conhecimento do funcionamento do mercado de trabalho português e permitirá retirar conclusões em termos de política económica. Começaremos por uma revisão da literatura sobre os efeitos do subsídio de desemprego nos esforços de procura de emprego dos beneficiários, no tempo que permanecem no desemprego e na qualidade dos empregos que encontram. Depois de analisados os modelos de procura de trabalho e de escolha entre trabalho e lazer, discutem-se as abordagens que referem a monitorização, as sanções e a articulação com outras políticas activas de emprego como soluções para reduzir os efeitos adversos da atribuição do subsídio de desemprego. Seguidamente, analisamos que factores condicionam a entrada no emprego a tempo parcial no contexto da economia portuguesa. Complementamos a evidência disponível nos estudos já realizados, fazendo uma distinção entre a entrada no emprego a horário parcial por conta de outrem e por conta própria. Desenvolveremos a análise para cada um dos géneros separadamente para aferir se as políticas que visam aumentar a taxa de emprego parcial devem ser diferenciadas. Ainda relacionado com o emprego a tempo parcial, utilizaremos uma experiência natural para avaliar se o aumento do subsídio de desemprego parcial, introduzido em Portugal no primeiro trimestre de 2003, incentivou a aceitação destes empregos pelos beneficiários de subsídio de desemprego. Sobre o auto-emprego, com recurso a uma experiência natural, tentaremos aferir se um aumento do valor das contribuições para a segurança social desmotiva o desenvolvimento de actividades por conta própria e/ou condiciona a sua duração. Por último, estudaremos qual o perfil dos indivíduos que se tornam trabalhadores independentes e identificaremos que factores contribuem para aumentar a probabilidade da actividade por conta própria ser encerrada, fazendo uma diferenciação entre transições para o trabalho assalariado e para a inactividade/desemprego.<br>Recently, several reforms have been introduced in the Portuguese social protection system. This thesis will try to understand how these changes affected the occupational choices of active adults, and will also assess the efficiency of the new policies in meeting the established goals. A survey, on the effects of unemployment insurance on job search efforts, unemployment duration, and the quality of the following jobs, is presented in chapter 1. Both job search models and leisure-consumption decision models are discussed, as well as an argument from research that monitoring, sanctions and active labour market policies are a solution for decreasing moral hazard among unemployment insurance beneficiaries. In addition, we also study the determinants for entry into part-time jobs in the Portuguese economy. This analysis complements the available empirical evidence by distinguishing between entry into self-employment part-time jobs and entry into wage sector part-time jobs. This research also shows whether policies implemented to foster part-time employment should be gender sensitive. Furthermore, a natural experiment will be used to evaluate whether an increase in partial unemployment insurance raises the likelihood of a part-time job being chosen by an unemployment insurance beneficiary. Finally, this study also analyzes the determinants of entry into self-employment as well as the factors influencing the duration of self-employment in Portugal. We exploit a natural experiment to assess whether increases in social security contributions rates have influenced the likelihood of entry into self-employment.

L’objectif de cette thèse est de développer une approche plus différenciée et gradualiste des mobilités que celle proposée par les principales options théoriques en vigueur, sans pour autant abandonner la dimension fluctuante, non linéaire et imprévisible du mouvement sur laquelle elles attirent l’attention. Qu’est-ce qu’être mobile ?Une théorie de l’expérience, en l’occurrence celle proposée par la phénoménologie, offrirait-elle des ressources critiques susceptibles d’ouvrir à l’approfondissement des mobilités comme elles sont vécues ?À titre d’hypothèse, cette thèse pose qu’un ensemble de phénomènes demeurent énigmatiques à l’intérieur de la conception généralement admise du social contemporain et qu’une articulation plus explicite du thème de la mobilité à celui de l’action humaine permet d’approfondir les processus du déplacement dans l’espace des sociétés, du passage du temps impliqué par le déplacement et du changement social. Comment émerge du nouveau dans le cours d’actions ?Qu’est-ce que pouvoir agir ?Quelle est la source du changement ?À partir d’une enquête inédite sur des voyageurs se rendant quotidiennement à Bruxelles et des personnages de romans de route étatsuniens, l’auteur explore des questions de fond portant sur l’expérience du transport, autour de l’éloignement des choses et des personnes aimées, du vide du temps d’attente, des aléas aussi insignifiants qu’irritants, de l’étrangeté des rencontres, de la décision de prendre la route et de choisir une orientation nouvelle. Ces moments de vacillation sont importants, soutient l’auteur, car ils nous ramènent aux motivations fondamentales et aux buts ultimes de nos déplacements les plus quotidiens. À une époque marquée par un idéal de mouvement fluide et sans accrocs, cette thèse éclaire ce qui se passe dans l’expérience des mobilités. Elle incite à une réflexion sur ce que nous éprouvons sur la route et aux possibles que cette expérience fait émerger.<br>Doctorat en Sciences politiques et sociales<br>info:eu-repo/semantics/nonPublished

Full textAbstract:
2006/2007<br>Beyond the myth and despite some mistakenly reported exceptional properties literature is plenty of, the special role of trehalose and its structural organisation at mesoscale in bioprotection seems to be a fact. This justifies the great effort in the scientific community trying to understand the molecular mechanism(s) underlying bioprotection. The comprehension of the bioprotective phenomenon is expected to have a strong impact in several fields ranging from food industry to biomedical and nanopharmaceutical applications. In front of the many different hypotheses stated in the past, the advantages of trehalose nowadays appear to come from a combination of factors and not from a single exceptional property.
In this thesis work we present some new important features apparently ignored. The first set of experiments deal with the structural organisation of glassy/amorphous trehalose in the absence of water. While different crystalline polymorphs have already been recognised and characterised, in this work for the first time evidence of the existence of two different glasses is provided. Characterization of the glasses has been carried out by studying the process of physical aging with the result that different molecular mobility and different activation energies are deduced for the two glasses. In addition to discuss the role these findings may have in bioprotection, the other heuristic result is that the existence of two amorphous forms of trehalose may explain one literature ambiguous crystallisation behaviour of the amorphous phase (previously considered random).
In the second set of experiments, Brillouin light scattering (BLS) experiments on a wide range of concentrations of water-trehalose solutions at different temperatures were performed to explore the density fluctuations (nanoscale inhomogeneities) in the solution. A traditional acoustic analysis was carried out and the parameters describing propagating and dissipative properties were examined in the framework of two different formalisms for characterising the structural relaxation process present in this frequency range. It was found that an increase in trehalose concentration slows down the dynamics, affecting the characteristic time tau. Moreover, the activation energy of the process has a only slight dependence on temperature for diluted and semi diluted systems, that could be attributed to local hydrogen bonding.<br>XX Ciclo<br>1977

Il est aujourd’hui admis que les semi-conducteurs à large bande interdite vont permettre de repousser les frontières atteintes à ce jour dans le domaine de la génération de puissance hyperfréquence. L’analyse des principaux critères technologiques (physiques et électriques) des matériaux grands gap, et plus précisément du GaN montre que ce dernier est un candidat sérieux pour les applications de télécommunications et radar. Un modèle électrothermique de ces transistors hyperfréquences à FET sur GaN a été utilisé dans ces travaux pour analyser les comportements transitoires lents dus aux effets thermiques et aux effets de pièges. Une comparaison des performances en puissance, rendement et linéarité a été faite entre les résultats de simulation et ceux de mesure pour des signaux de deux types : CW impulsionnels et Bi porteuses impulsionnels. L’utilisation de signaux CW impulsionnels a permis une validation pratique des modèles électrothermiques de transistors HBT et une expertise de différentes filières technologiques de ces transistors.

The analysis of the properties of wide band-gap materials, and especially the GaN material, highlights that it is a serious candidate for telecommunication and radar applications. RF field effect transistors on GaN are prone to show dispersive behaviors due to heating and trapping effects. A non linear electrothermal model of these high frequency FETs transistors on GaN used in this work makes possible the analysis of dispersive behaviors due to heating and trapping effects. A comparison of performances in terms of output power, power added efficiency and linearity has been made between simulation and measurement results for two type of excitation: one tone pulsed signal and two tones pulsed signal. The use of a one tone pulsed excitation permitted the validation of an HBT electrothermal model and the expertise of different technological process of these transistors. The use of a two tone pulsed excitation has permitted to observe the trade-offs between power added efficiency and linearity versus trapping effects. The measurements carried out on an original configuration of the load pull set up for intermodulation measurements under pulsed conditions had shown the actual limitations of the transistor model

Full textAbstract:
A travers une enquête menée dans quatre Maisons d’Enfants à Caractère Social du département du Rhône, cette thèse interroge les rôles des déplacements et de la mobilité des adolescents en contexte de placement. Intégré au double dispositif de l’Aide Sociale à l’Enfance et de la Protection Judiciaire de la Jeunesse, le placement en établissement correspond à la prise en charge, en dehors de son domicile familial, d’un mineur pour une durée donnée. Tant dans ses objectifs que dans ses modalités de mise en œuvre, cette action sociale possède une dimension spatiale forte. Elle est en effet fondée sur l’articulation entre distance et proximité aux espaces familiers d’un côté, et discontinuité et continuité entre l’intérieur et l’extérieur de l’établissement de l’autre. Dans ce contexte, les déplacements des adolescents et leur mobilité jouent des rôles à trois niveaux. Pour les adolescents, pour qui le foyer correspond à un espace de résidence, se déplacer permet d’articuler des espaces d’attachements multiples. La mobilité a également un rôle d’ajustement entre les différents individus présents au sein de l’établissement, qui intervient dans l’usage qu’en font les éducateurs, pour qui le foyer est un espace de travail. Enfin, qu’elle soit autonome ou contrainte, la mobilité, au niveau institutionnel, permet la régulation entre différents systèmes de normes mais n’apparaît pas comme une valeur en soi<br>This thesis questions the role of mobility and how teenagers placed in institutional foster care move around, through a research conducted in four social care facilities (Maisons d’Enfants à Caractère Social). Within the French child protection system (Aide Sociale à l’Enfance and Protection Judiciaire de la Jeunesse), this form of placement means that a minor is taken care of outside of her/his family home during a given period of time. This type of social care presents a significant spatial dimension, both in its objectives and ways of implementation. It is indeed based on two principles: it seeks to manage both distance and proximity to familiar spaces on the one hand, and the discontinuity and continuity between the inside and the outside of the facility on the other hand. Within this context, how teenagers move around and their mobility play a three-layered role. First, for the teenagers themselves: the foster care facility is their space of residence, and moving around makes it possible for them to deal with multiple spaces of belonging. Second, for the social workers: the facility is their working space, and they use mobility as a means to both handle relationships between themselves and the teenagers, and adjust the number of teenagers they work with based on group dynamics and other parameters. Third, at an institutional level: whether it is chosen or coerced, mobility allows the regulation between different norm systems but is not perceived as being valuable in and of itself

L'objet de cette recherche consiste à présenter une analyse économique et statistique, à partir de données individuelles et régionales, de la mobilité géographique de l'insertion professionnelle des diplômés de l'enseignement supérieur en France. L'approche théorique a permis de passer en revue les différents travaux économiques qui ont incorporé la mobilité géographique dans leurs schémas généraux, principalement la théorie d'investissement en capital humain et celle de recherche d'emploi. Une attention particulière a été accordée aux différentes approches méthodologiques et aux principaux problèmes techniques liés à l'étude du phénomène migratoire. Dans ce contexte, l'approche à deux niveaux, "micro et macro" de l'analyse, a été retenue afin de générer une interprétation complète et convaincante d'un processus particulièrement complexe. La partie empirique est formée de deux composantes, une analyse agrégée de la mobilité interrégionale et un traitement micro-économétrique de ce même processus. Un premier balayage de la mobilité géographique de l'insertion professionnelle a été réalisé par le biais d'une étude de l'attraction et de la rétention régionale des nouveaux entrants sur le marché du travail. Un test de la nature du mécanisme de la mobilité a été ensuite appliqué. Le modèle gravitationnel a ainsi permis l'analyse des flux interrégionaux de la trajectoire "globale" de l'insertion. Dans l'approche micro-économétrique, l'étude du choix régional a été abordée, dans une première étape, dans le cadre d'un modèle structurel d'affectation spatiale<br>The object of this research is to present a statistical and economic analysis of the professional insertion geographical mobility's, from regional and individual data concerning the French college graduates'. The theoretical approach has allowed passing in review the different economic works that have incorporated the geographical mobility in their general diagrams, mainly the theory of human capital investment and that of job search. A particular attention has been granted to the different methodological approach and to the main technical problems linked to the study of the migratory phenomenon. In this context, the two levels approach, "micro and macro" of the analysis, has been retained so as to generated a convincing and complete interpretation of this particularly complex process. The empirical part is divided on two components, an aggregated analysis and a microeconometric processing of the interregional mobility. A first sweeping of the professional insertion geographical mobility's has been realized. A study of the regional attraction and retention of the new entrants on the labour market was formulated and tested. A test of the mobility mechanism has been then applied. The gravitational model has thus permits to analyze interregional flows and the "global" path of the insertion. In the micro-econometric approach a study of the regional choice has been approached, in a first step, and in the framework of a structural model of spatial allocation

<p>The primary aim of these coal fired industries for co-disposing fly ash and brine was to use the fly ash as a sustainable salt sink. It is therefore important to study the interaction chemistry of the fly ash-brine systems to fully understand the leaching and mobility of the contaminant species, and to determine the possibility of capturing the salts from the brine solution when fly ash and brine are co-disposed. In order to achieve the aims and objectives of this study, several leaching procedures such as batch reaction tests, long-term fly ash-brine interaction tests, acid neutralization capacity (ANC) tests, up-flow percolation tests and sequential extraction tests were employed. The geochemical modeling software was applied to predict the formation of secondary mineral phases controlling the release of species in the fly ash-brine systems. Several analytical techniques such as x-ray diffraction (XRD), x-ray fluorescence (XRF), scanning electron microscopy-energy dispersion spectroscopy (SEM-EDS), inductively coupled plasma-mass spectroscopy (ICP-MS) and ion chromatography (IC) were applied to characterize the fresh fly ashes, solid residues recovered from the fly ash-brine interaction tests, the brine sample used in this study and the leachate samples in order to determine the chemical and mineralogical compositions and speciation of the waste materials.</p>

Questa attività di ricerca è focalizzata sullo sviluppo di algoritmi e soluzioni per ambienti intelligenti sfruttando sensori RGB e di profondità. In particolare, gli argomenti affrontati fanno riferimento alla valutazione della mobilità di un soggetto e al riconoscimento di azioni umane.
Riguardo il primo tema, l'obiettivo è quello di implementare algoritmi per l'estrazione di parametri oggettivi che possano supportare la valutazione di test di mobilità svolta da personale sanitario. Il primo algoritmo proposto riguarda l'estrazione di sei joints sul piano sagittale utilizzando i dati di profondità forniti dal sensore Kinect. La precisione in termini di stima degli angoli di busto e ginocchio nella fase di sit-to-stand viene valutata considerando come riferimento un sistema stereofotogrammetrico basato su marker. Un secondo algoritmo viene proposto per facilitare la realizzazione del test in ambiente domestico e per consentire l'estrazione di un maggior numero di parametri dall'esecuzione del test Timed Up and Go. I dati di Kinect vengono combinati con quelli di un accelerometro attraverso un algoritmo di sincronizzazione, costituendo un setup che può essere utilizzato anche per altre applicazioni che possono beneficiare dell'utilizzo congiunto di dati RGB, profondità ed inerziali. Vengono quindi proposti algoritmi di rilevazione della caduta che sfruttano la stessa configurazione del Timed Up and Go test.
Per quanto riguarda il secondo argomento affrontato, l'obiettivo è quello di effettuare la classificazione di azioni che possono essere compiute dalla persona all'interno di un ambiente domestico. Vengono quindi proposti due algoritmi di riconoscimento attività i quali utilizzano i joints dello scheletro di Kinect e sfruttano un SVM multiclasse per il riconoscimento di azioni appartenenti a dataset pubblicamente disponibili, raggiungendo risultati confrontabili con lo stato dell'arte rispetto ai dataset CAD-60, KARD, MSR Action3D.<br>This research activity is focused on the development of algorithms and solutions for smart environments exploiting RGB and depth sensors. In particular, the addressed topics refer to mobility assessment of a subject and to human action recognition.
Regarding the first topic, the goal is to implement algorithms for the extraction of objective parameters that can support the assessment of mobility tests performed by healthcare staff. The first proposed algorithm regards the extraction of six joints on the sagittal plane using depth data provided by Kinect sensor. The accuracy in terms of estimation of torso and knee angles in the sit-to-stand phase is evaluated considering a marker-based stereometric system as a reference. A second algorithm is proposed to simplify the test implementation in home environment and to allow the extraction of a greater number of parameters from the execution of the Timed Up and Go test. Kinect data are combined with those of an accelerometer through a synchronization algorithm constituting a setup that can be used also for other applications that benefit from the joint usage of RGB, depth and inertial data. Fall detection algorithms exploiting the same configuration of the Timed Up and Go test are therefore proposed.
Regarding the second topic addressed, the goal is to perform the classification of human actions that can be carried out in home environment. Two algorithms for human action recognition are therefore proposed, which exploit skeleton joints of Kinect and a multi-class SVM for the recognition of actions belonging to publicly available datasets, achieving results comparable with the state of the art in the datasets CAD-60, KARD, MSR Action3D.

Contraints par une pollution anthropique croissante, les environnementalistes explorent les avenues possibles pour réduire les émissions de contaminants émis en milieu urbain. Afin d'y parvenir, l'organisation du territoire favorisant le transport durable apparaît comme une alternative permettant de réduire l'empreinte écologique des déplacements quotidiens des habitants et ainsi de diminuer la pollution globale des villes. En effet, l'aménagement privilégiant un transport plus durable promeut une mixité des modes de transport et une proximité des usages à l'échelle des quartiers. En rapprochant la distance entre les usages, le transport actif, la forme la plus écologique de transport, devient plus attrayant pour la mobilité urbaine. La présente étude se penche sur neuf études de cas américaines et canadiennes en aménagement qui font la promotion du transport actif sur leur territoire. La recension des écrits révèle que plusieurs paramètres tels que la mixité des usages, la proximité, la connexion et certaines propriétés des réseaux piétonniers ou cyclables sont nécessaires à la mise en place d'un aménagement favorisant les déplacements en vélo et à pied. Ainsi, à l'aide d'une grille d'analyse rigoureuse, la description et la comparaison de certaines variables ont été réalisés [i.e. réalisées]. Il en ressort que la proximité est généralement bonne alors que la connectivité est plutôt modérée. Les propriétés des réseaux sont très spécifiques à chacune des études de cas, mais elles témoignent d'une certaine unité. Les variables relatives à l'environnement, à la sécurité, aux coûts et à la ségrégation des voies sont relativement présentes tandis que celles touchant au design, au confort, au mobilier, aux infrastructures lourdes et à l'entretien le sont beaucoup moins. Ces analyses permettent de mettre de l'avant certaines pratiques et d'émettre des recommandations pour de futurs projets en aménagement favorisant le transport actif.

Full textAbstract:
Depuis le milieu des années 2010, de nombreuses villes moyennes françaises ont élaboré des projets de revitalisation pour leurs centres-villes — notamment sous l’impulsion de l’État, au travers du programme Action cœur de ville ou du Nouveau programme national de renouvellement urbain (NPNRU). Dans ces quartiers, la propriété privée et le secteur locatif privé sont largement prédominants. En même temps, les villes moyennes bénéficient de moins de moyens humains et financiers, d’outils et d’opérateurs d’aménagement et de production immobilière que des villes plus peuplées. En dépit de ces difficultés, les acteurs publics locaux des villes moyennes cherchent à mettre en place des politiques de peuplement dans les centres-villes. Pour comprendre ce paradoxe, a été mis en œuvre un protocole de recherche associant une analyse statistique à celle de données qualitatives. Ces dernières ont été recueillies au travers d’une analyse documentaire, d’une campagne d’entretiens auprès des acteurs publics et d’une observation participante conduite dans le cadre d’une convention industrielle de formation par la recherche (CIFRE) dans une coopérative d’études. Les résultats portant sur un échantillon de neuf villes moyennes montrent que les centres anciens constituent des types de territoires particulièrement singuliers du point de vue de leur peuplement. Du fait de la spécialisation du parc résidentiel dans les petits appartements du secteur locatif privé, ils constituent des quartiers d’accueil — essentiels à la fluidité des parcours résidentiels dans les villes moyennes — pour les personnes en situation de rupture(s) biographique(s) : décohabitation du domicile parental, séparation conjugale ou veuvage, migration interrégionale ou internationale, précarité professionnelle… Parallèlement, ces caractéristiques en font globalement des espaces d’une grande et croissante mixité socioprofessionnelle — en dépit de l’hétérogénéité des villes moyennes et de leurs centres-villes. Pourtant, dans leur ensemble, les acteurs publics souhaitent déployer des politiques au nom de la mixité sociale dans les centres-villes, au travers des projets urbains visant à la revitalisation. L’enquête qualitative conduite dans trois terrains (Colmar, Romans-sur-Isère et Tulle) montre que cela s’explique par un rapport de cause à effet établi entre le constat d’un déclin du centre-ville — affaiblissement du tissu commercial, dégradation du bâti et de l’environnement urbain, etc. — et la représentation d’un peuplement « déséquilibré » dans le quartier. En addition, l’appropriation de la mixité sociale comme norme de l’action publique et le cadrage opéré par les dispositifs nationaux contribuent à renforcer l’attachement des acteurs locaux à l’idée d’une diversification du peuplement. Afin d’atteindre leur objectif de peuplement que constitue l’attraction de couples avec enfants de classe moyenne en propriété occupante — identifié comme un levier de revitalisation —, les acteurs publics élaborent des projets consistant à rapprocher l’habitat des centres-villes de celui proposé dans les territoires périurbains. Dans leur élaboration, les projets de revitalisation témoignent de l’internalisation d’un cadrage marchand de l’habitat par les acteurs publics. Il se double d’un rapprochement avec les acteurs privés dans leur mise en œuvre.Mais, les velléités de diversification du parc résidentiel des acteurs locaux se heurtent au faible nombre d’opérateurs de production de logements présents — pour l’essentiel, des bailleurs sociaux — et aux conditions sociales du dispositif national de renouvellement urbain. Par conséquent, les opérations immobilières déployées avec le soutien des acteurs publics ne vont pas dans le sens d’une diversification du parc résidentiel et du peuplement des centres-villes. Néanmoins, elles permettent de gommer les marqueurs du déclin urbain, dans l’espoir, aux yeux des acteurs publics, d’un « retour » des ménages et des investisseurs privés<br>Since the mid-2010s, many medium-sized French towns have been developing projects to revitalise their town centres - particularly at the instigation of the national government, through the Action cœur de ville programme or the New National Urban Renewal Programme (NPNRU). In these areas, private property and the private rental sector predominate. At the same time, medium-sized towns have fewer human and financial resources, tools and operators for development and property production than towns with larger populations. Despite these difficulties, local governments in medium-sized towns are seeking to implement social mix policies in town centres. To understand this paradox, I implemented a research protocol that combined statistical analysis with qualitative data. I collected qualitative data through a documentary analysis, a series of interviews with public stakeholders and participant observation conducted as part of a consulting cooperative.The results of a sample of nine medium-sized towns show that old town centres are particularly unique in terms of their social and demographic structure. Because of the specialisation of the residential stock in small private rental flats, this type of neighbourhoods is essential to the fluidity of residential course in medium-sized towns as they are adequate for people experiencing one or more biographical disruptions: moving out of the parental home, marital separation or widowhood, inter-regional or international migration, job insecurity, and so on. At the same time, these characteristics mean that, overall, they are areas with a large and growing socio-professional mix - despite the heterogeneity of medium-sized towns and their town centres.However public authorities are keen to implement policies to promote social diversity in town centres, through urban revitalisation projects. The qualitative study conducted in three sites (Colmar, Romans-sur-Isère, and Tulle) shows that this is due to the establishment of a cause-and-effect relationship between the decline of town centres and the representation of an "unbalanced" population. In addition, the adoption of social mix as a norm for public action and the framing provided by national policies strengthen the attachment of local players to the idea of diversifying the population.To attract their target, which are middle-class couples with children into owner-occupation - identified as an urban revitalisation lever - the public actors are developing projects that aim to close the gap in terms of housing between town centres and suburban areas. Doing so, revitalisation projects reflect the internalisation of a commercial framework for housing policies by public players. They also contribute to closer relationships between local government and private players in their implementation.However, the efforts of local stakeholders to diversify the housing stock are hindered by the small number of housing production operators - mainly social landlords - and by the social conditions of the French national urban renewal scheme, dating back from the 1970's. As a result, the property developments supported by the public sector are not helping to diversify the housing stock nor the population of town centres. However, they do help to erase the traces of urban decline, in the hope of a 'return' of households and private investors by the local authorities

Les évolutions socio-économiques et les organisations administratives imposent un recrutement massif des intervenants sociaux pour accompagner, aider et soutenir les personnes en situation de rejet et disqualification sociale. Deux modes de recrutement (l'un fondé sur les compétences et l'autre sur les qualifications) se côtoient. Ils répondent aux attentes des employeurs soucieux de l'efficacité de la couverture des territoires de leurs interventions et aux besoins des populations de plus en plus informées et exigeantes. Des professionnels aux statuts, aux qualifications et aux compétences différentes coexistent au sein d'un même établissement. Bien qu'hétérogènes, leurs activités se chevauchent et quelquefois similaires. Des missions initialement prévues pour des professionnels d'un niveau donné par d'autres dont le niveau de qualification est inférieur. D'où un sentiment de non reconnaissance des plus qualifiés et une recomposition de tous ceux inscrits dans le secteur social<br>The socioeconomic evolutions and the administrative organisations are forcing a mass recruitment of social workers to give, to help and to back the people in a situation of rejection and social exclusion. Two way of recruiting (one founded on skills and the other on qualifications) live side by side. They answer the expectations of the employers who are looking for efficiency, a way to cover whole areas and they also answer the needs of population who are more and more informed and demanding. Thus, professionals with different status, qualifications and skills work side by side in the same structure. Al though they are heterogeneous, their activities overlap and sometimes similar. That is how missions initially, planned for a given level are conducted in an indifferentiated way by professionals of a lower level. All this engenders a feeling of non recognition among the more qualified and a recomposition off all the workers registered in the social sector
