L’estimation des matrices origine-destination (OD) est un sujet de recherche important depuis les années 1950. En effet, ces tableaux à deux entrées recensent la demande de transport d'une zone géographique donnée et sont de ce fait un élément clé de l'ingénierie du trafic. Historiquement, les seules données disponibles pour leur estimation par les statistiques étaient les comptages de véhicules par les boucles magnétiques. Ce travail s'inscrit alors dans le contexte de l'installation à Brisbane de plus de 600 détecteurs Bluetooth qui ont la capacité de détecter et d'identifier les appareils électroniques équipés de cette technologie.Dans un premier temps, il explore la possibilité offerte par ces détecteurs pour les applications en ingénierie du transport en caractérisant ces données et leurs bruits. Ce projet aboutit, à l'issue de cette étude, à une méthode de reconstruction des trajectoires des véhicules équipés du Bluetooth à partir de ces seules données. Dans un second temps, en partant de l'hypothèse que l'accès à des échantillons importants de trajectoires va se démocratiser, cette thèse propose d'étendre la notion de matrice OD à celle de matrice OD par lien afin de combiner la description de la demande avec celle de l'utilisation du réseau. Reposant sur les derniers outils méthodologies développés en optimisation convexe, nous proposons une méthode d'estimation de ces matrices à partir des trajectoires inférées par Bluetooth et des comptages routiers.A partir de peu d'hypothèses, il est possible d'inférer ces nouvelles matrices pour l'ensemble des utilisateurs d'un réseau routier (indépendamment de leur équipement en nouvelles technologies). Ce travail se distingue ainsi des méthodes traditionnelles d'estimation qui reposaient sur des étapes successives et indépendantes d'inférence et de modélisation. / Origin Destination matrix estimation is a critical problem of the Transportation field since the fifties. OD matrix is a two-entry table taking census of the zone-to-zone traffic of a geographic area. This traffic description tools is therefore paramount for traffic engineering applications. Traditionally, the OD matrix estimation has solely been based on traffic counts collected by networks of magnetic loops. This thesis takes place in a context with over 600 Bluetooth detectors installed in the City of Brisbane. These detectors permit in-car Bluetooth device detection and thus vehicle identification.This manuscript explores first, the potentialities of Bluetooth detectors for Transport Engineering applications by characterising the data, their noises and biases. This leads to propose a new methodology for Bluetooth equipped vehicle trajectory reconstruction. In a second step, based on the idea that probe trajectories will become more and more available by means of new technologies, this thesis proposes to extend the concept of OD matrix to the one of link dependent origin destination matrix that describes simultaneously both the traffic demand and the usage of the network. The problem of LOD matrix estimation is formulated as a minimisation problem based on probe trajectories and traffic counts and is then solved thanks to the latest advances in nonsmooth convex optimisation.This thesis demonstrates that, with few hypothesis, it is possible to retrieve the LOD matrix for the whole set of users in a road network. It is thus different from traditional OD matrix estimation approaches that relied on successive steps of modelling and of statistical inferences.

Certains chercheurs veulent que les gouvernements modifient les déterminants de l’environnement urbain du transport actif dans des régions à bas statut socioéconomique pour réduire les inégalités en activité physique et santé. Mais, des individus de différents sousgroupes de la population pourraient réagir différemment à l’environnement urbain. Plusieurs chercheurs ont examiné si l’influence d’un environnement urbain propice aux piétons sur le transport actif diffère entre les personnes ayant un statut socioéconomique de quartier différent et ont obtenu des résultats mixtes. Ces résultats équivoques pourraient être dus à la façon dont les mesures de l’environnement urbain étaient déterminées. Plus spécifiquement, la plupart des études ont examiné l’effet de la propicité à la marche des lieux résidentiels et n’ont pas pris en compte les destinations non-résidentielles dans leurs mesures. Cette étude a examiné le statut socioéconomique du quartier comme modérateur de la relation entre l’environnement urbain et le transport actif en utilisant des mesures d’environnement urbain qui proviennent de toute la trajectoire spatiale estimé des individus. Les trois variables de l’environnement urbain, la connectivité, la densité des commerces et services et la diversité du territoire avaient une plus grande influence sur le transport actif de ceux avec un haut statut socioéconomique. Nos résultats suggèrent que même quand la configuration de l’environnement urbain est favorable pour le transport actif, il peut y avoir des barrières sociales ou physiques qui empêchent les gens qui habitent dans un quartier à bas statut socioéconomique de bénéficier d’un environnement urbain favorable au transport actif. / Researchers have called for policymakers to modify the built environment determinants of active travel in low SES areas in the hopes of reducing disparities in physical activity and health. However, different population sub-groups may be differently responsive to the built environment. Researchers have examined whether the influence of walkable built environments on active transportation differs for those of different socio-economic status and have obtained mixed results. These equivocal findings could be due to the way the built environment measures were determined. More specifically, most studies have examined walkability in residential settings ignoring non-residential destinations. This study examined socio-economic status as a moderator of the relationship between the built environment and active transportation using a trip level analyses with measures of built environment exposure derived from the estimated spatial trajectory of transport trips. All three of the environmental variables, connectivity, density of business and services, and land-use mix, were found to have a greater association with AT if the individual undergoing the trip was from a high socioeconomic status neighbourhood. Our findings suggest that even when the built environment is favourable for AT there may be social or physical barriers that prevent those from low socio-economic status neighbourhoods from benefitting from built environments that are conducive to active transportation.

El presente proyecto responde a la necesidad de mantener, conservar y sostener en el tiempo, uno de los destinos naturales de nuestro país, como son las dunas del Desierto de Paracas, cuyo valor se trata de potenciar al crear un Ecolodge con énfasis en la Arquitectura Bioclimática. Paracas, a pesar de ser uno de los destinos preferidos por los turistas nacionales y extranjeros, no cuenta con una capacidad hotelera que pueda satisfacer los nuevos requerimientos en cuanto a hoteles con principios ecológicos. En tal sentido, se plantea un Ecolodge, donde el diseño y elementos constructivos a utilizarse estarán básicamente en función del clima de Paracas que se muestra soleado durante todo el año y acompañado de fuertes vientos. Esta nueva modalidad de hospedaje, se sustenta en principios de conservación y protección del medio ambiente, así como en el mejor aprovechamiento de la energía solar cuyos pilares son la captación, acumulación y distribución eficiente de la energía generada. Se toma en cuenta también el manejo de residuos, y el consumo responsable del agua con la finalidad de poderla reutilizar a través del sistema de riego por goteo, y generando además programas que beneficien directamente al desarrollo de la localidad y sus comunidades. / The purpose of this project is to maintain, preserve, and sustain throughout time, one of the main ecotourism destinations in our country, such as the Paracas Desert dunes. We aim to increase the value of this location through the development of an Ecolodge, with a focus on Bioclimatic Architecture. Given that Paracas is one of the preferred destinations by both foreign and local tourists, its main issue revolves around the lack of hotels that can satisfy new requirements in terms of ecological principles. In this context, raices the idea of an Ecolodge, where the design and building materials used will be selected in accordance with the Paracas climate, which is comprised of year-long sunshine accompanied by strong winds. The new hospitality approach is based upon conservation and environmental protection principles, as well as an improved use of solar energy, whose pillars include the collection, accumulation, and efficient distribution of energy. Waste management and responsible consumption of water is taken into account as well, with the purpose of re-utilizing water via a drip irrigation system. Finally, the strategy will ultimately generate programs that will directly benefit the development of local communities. / Tesis

To be successful, tourism requires investment, inputs, appropriate planning and management, like any other economic activity. A fundamental goal of the destination management is to understand how the competitiveness of a tourist destination can be improved and sustained. Competitive position of tourism can be measured and assessed by various models. Evaluating the indicators of competitiveness of a tourist destination involves a multivariate analysis, ranging from issues directly related to tourism activity itself to the indirect factors. These are elements that are interrelated and that together will point out the competitive condition of this destination. From the definition and characterization of competitiveness, sustainability and management in the context of tourist destinations, understood as the main concepts of this study, we present the main theoretical and methodological models of assessment of competitiveness of tourist destinations in the literature and represent the state of the issue in the scientific treatment of the subject. These models, designed by researchers from several countries and applied in different tourist destinations, are confronted about their structure, indicators considered and localities in which they were applied. The aim of this study was to know and evaluate the condition of tourist competitiveness of the destination P?lo Costa das Dunas, from the constraints attributes of superior performance of the evaluation model of tourist competitiveness of destinations Competenible, suggested by Mazaro, and that suit the requirements of international market aware of the strength and importance of sustainability. The condition of competitiveness of tourist destination in Rio Grande do Norte P?lo Costa das Dunas was moderate. The competitive strengths and weaknesses of the destination P?lo Costa das Dunas revealed through the dozens of sustainable attributes of the model Competenible showed guidelines and initiatives that can be taken to guide strategic decisions related to their planning and management. Thus, this study should serve as support for strategic planning and long-term management of the sector and as a crucial tool for making decisions related to public policies, sectoral investments, monitor processes, strategic planning, direction and control of the local and regional tourism development of destinations / Estar dispon?vel como destino tur?stico ? uma condi??o necess?ria, mas n?o suficiente para a expans?o e ?xito da atividade do turismo. Para ser bem-sucedido, o turismo requer investimentos, insumos, planejamento e gest?o adequados, como qualquer outra atividade econ?mica. Um dos objetivos fundamentais da gest?o de destino ? entender como a competitividade de um destino tur?stico pode ser melhorada e sustentada. A posi??o competitiva do turismo pode ser mensurada, medida e avaliada por diversos modelos. Avaliar os indicadores da competitividade de um destino tur?stico envolve uma an?lise multivariada, que vai desde aspectos ligados diretamente a atividade do turismo em si a fatores indiretos.

The aim of the thesis was a proposal to form a tourist information center and its location in the village of Tři Studně. Based on the analysis of supply and demand of the tourist destination offers a service that will provide visitors information center. For tourist information center have been proposed two alternatives. The first draft took advantage of the current meeting room of the Municipal Office at Tři Studně without modification, and it only added new equipment and technology . The second proposal is already associated with structural modifications of the room. Tři Studně are due to its abundant natural potential tourists visited in the summer and winter months. It forms one of the most Important Recreational Areas in Vysočina. Tři Studně in the TIC will be one of the most important elements of marketing communication of the village and its vicinity.

Syfte: Syftet med denna uppsats är att undersöka hur företag inom besöksnäringen i Stockholms skärgård samarbetar och om samarbete kan leda till längre säsonger. Samt huruvida de statligt finansierade utvecklingsprojekten i skärgården bidragit till längre säsonger enligt de undersökta företagen. Metod: I denna studie har en kvalitativ metod i form av semi-strukturerade intervjuer används för insamling av empiri. Sex företag på två skärgårdsöar har intervjuats och används som empiriskt huvudmaterial men även en intervju som gjorts med Värmdö kommun har fått ligga till grund för en del av det empiriska materialet. Slutsatser: Det har under studien framkommit att samarbete mellan lokala aktörer är en viktig del i utvecklingen av destinationen. Samarbetet är inte bara en del i utvecklingen utan kan också vara en hjälp till att förlänga säsongerna. Utvecklingsprojekten har enligt företagarna som intervjuats ej gynnat dem. Det framgår att företagarna anser att det är de själva som måste jobba hårt om de ska se någon förändring. / Purpose: The purpose of this paper is to investigate how companies in the tourism industry in the Stockholm archipelago cooperate and whether cooperation can lead to longer seasons. As well as if the state-funded development projects in the archipelago have contributed to longer seasons according to the investigated companies. Methodology: In this study, a qualitative method in the form of semi-structured interviews has been used for the gathering of empirical data. Six companies on two archipelago islands have been interviewed and used as main empirical material, but an interview with Värmdö municipality has also formed the basis for some of the empirical material. Conclusions: During this study, it has been found that cooperation between local actors is an important part of the development of the destination. Not only is the cooperation a part of the destination development, it can also help extend the season. According to the interviewees, the development projects have not benefited them. It is apparent that the entrepreneurs believe that they themselves that must work hard for any change to happen.

Ce travail contribue à la définition des mesures de l'efficacité et de la productivité dans la théorie microéconomique. Il présente des apports théoriques et empiriques. En premier lieu, cette thèse élabore une critique sur certaines mesures classiques de l’efficacité et de la productivité. Il est montré que la mesure directionnelle, sous l'hypothèse de rendements d'échelle constants, pose un certain nombre de problèmes quant à l’évaluation des variations de la productivité. De plus, il est établi que la « slacks-based » et la directionnelle « slack-based » mesures (ou mesures de Färe-Lovell) ne permettent pas de caractériser la technologie de production. Il résulte que ce type de mesure ne permet pas d’évaluer l'efficacité et les variations de productivité. Une approche alternative est proposée qui permet de contourner cette difficulté. Ensuite, cette thèse introduit deux nouveaux indicateurs: un indicateur social de Luenberger-Hicks-Moorsteen et un indicateur de productivité généralisé. Le premier permet d'évaluer l'effet des politiques sur les capabilités au sens d'A. Sen. Il consiste en une transposition des indicateurs de Hicks-Moorsteen en considérant le rôle spécifique d’un sous-vecteur prenant en compte les facteurs sociaux. Le second indicateur généralise les indicateurs standards de productivité. Il permet de retrouver à la fois les indicateurs de Luenberger et le Luenberger Hicks-Moortsteen comme cas spéciaux de cet indicateur généralisé. En considérant la version multiplicative de l’indicateur généralisé, on retrouve comme cas particuliers, les indicateurs de Malmquist et le Hicks-Moorsteen. Enfin, cette thèse présente des applications empiriques qui illustrent la méthodologie. Ces études évaluent et comparent la performance des régions touristiques et plus précisément celle du Languedoc-Roussillon, qui mobilise un cadre d'analyse transfrontalier. / This phd contributes to the definition of efficiency measures and productivity indicator, in the microeconomic theory. It presents theoretical and empirical contributions. Firstly, this phd develops a review on standard measures of efficiency and productivity. It is shown that the directional measure, under the assumption of constant returns to scale, raises some problems in the assessment of productivity changes. Moreover, it is established that the "slacks-based" and directional "slack-based" measures (or Färe-Lovell measures) do not allow to characterize technology. It follows that such measures do not allow to evaluate efficiency and productivity changes. An alternative approach is proposed which overcomes this difficulty. Then, this phd introduces two new indicators: a social Luenberger-Hicks-Moorsteen indicator and a generalized indicator of productivity. The first mesure the impact of publics policies in the line of the capability theory introduce by A. Sen. This indicator consists on a transposition of the Hicks-Moorsteen indicator by considering a sub-vector of social factors. The second indicator generalizes standards productivity indicators. It allows to find the Luenberger and the Luenberger Hicks-Moortsteen as special cases of this general indicator. Considering the multiplicative version of the generalized indicator, on can find the Malmquist and Hicks-Moorsteen indicators, as special cases. Finally, this phd presents some empirical applications to illustrate the methodology. These studies evaluate and compare the performance of the tourist destination, and specifically for the Languedoc-Roussillon, which involves a cross-border analysis framework

The study is an investigation into the pathways of out-of-school youth and their re-entrance into the Education Training and Development (ETD) system or the labour market. In the study the pathways of youth who dropped out of school between grades 1 and 11 are traced as they seek re-entrance to the ETD system, or entrance into the labour market. Particular attention was given to the factors that determine the choices that dropouts make either in re-entering the ETD system or entering the labour market. An analysis of the experiences of the interviewed sample of dropouts is presented. The study employs a qualitative research methodology using interviews to elicit the experiences of dropouts and school managers. The participants (young people and three school principals) were selected through snowballing from a township south of Durban. Individual and focus group interviews were held. The findings provide evidence of the value of investing in education, as suggested by the youth. This is in line with the human capital theory framework that suggests that there are major benefits to investing in education. The study is concluded by suggesting the need for second chance education in South Africa. / Thesis (PhD)--University of Pretoria, 2011. / Education Management and Policy Studies / unrestricted

Remote communities stay vulnerable in the face of major socioeconomic challenges. Tourism is often seen as a way to stimulate local economies and increase attractiveness of peripheral destinations, while events are considered to be one of the tools to promote tourism. In this regard, local collaboration is deemed to be crucial for facilitating development in spatially remote areas, where social context plays an important role in formation of entrepreneurial networks. By using the case of a local community festival Aldrei fór ég suður (AFS) in Ísafjörður, Iceland, I investigate relationship between the festival and local tourism entrepreneurs and define opportunities that the festival might provide for sustainable development of the area. Based on data collected from 24 interviews, findings suggest that the impact of AFS on local businesses varies depending on the category of business, its location, seasonality and target group, whereas the festival also contributes to enhancement of destination image, extension of tourist season and attraction of new categories of visitors. Following theoretical framework of social capital and social embeddedness, the main role of the festival is found to be related to enhancement of community pride and contribution to social change within community. On the other hand, results demonstrate general lack of willingness to collaborate and suggest an increased risk of overembeddedness given the self-reliant nature of the festival and its reluctance to commercialization. Discussed suggestions for sustainable destination development include co-branding, packaging for extended stay, transportation options and usage of empty housing for temporary accommodation.
