Abstract:
La recesión de los años ochenta y la subsecuente reestructuración económica tuvieron un profundo impacto en la sociedad mexicana. No obstante, sus consecuencias sobre la movilidad social no fueron analizadas hasta finales de los noventa, cuando una serie de estudios empíricos revelaron las continuidades y los cambios en los patrones de movilidad social. En este artículo se discuten cuatro tendencias recientes: la continuidad de las altas tasas absolutas de movilidad intergeneracional; la reducción de las recompensas monetarias asociadas a la movilidad ocupacional; la creciente rigidez en las tasas relativas de movilidad; y el ajuste del caso mexicano al patrón de movilidad general propuesto por Erikson y Goldthorpe. El panorama que resulta de estas tendencias es el de una sociedad que, a pesar los efectos negativos de la crisis y los cambios estructurales de los años ochenta y noventa, ha mantenido altas tasas de movilidad social, pero sufre en otros aspectos como la calidad de las oportunidades de movilidad ascendente y la creciente desigualdad de oportunidades asociada a los orígenes de clase. El artículo concluye con una discusión sobre posibles líneas futuras de investigación de los estudios sobre movilidad social en México.Abstract: The recession of the 1980s and subsequent economic restructuring in the 1990s had a profound impact on Mexican society. However, the consequences in social mobility were not fully explored until the end of the 1990s, when a series of empirical studies revealed continuities and changes in mobility patterns. The purpose of this article is to discuss trends in intergenerational social mobility. Four findings are discussed: the continuity of high overall and upward mobility rates; the reduction of monetary gains associated to upward occupational mobility; the increasing rigidity in relative rates of occupational mobility; and the overall compliance of the Mexican case to Erikson and Golthorpe’s core model of social fluidity. The picture emerging from these findings depicts a society that, notwithstanding the negative effects of the economic recession and structural changes of the 1980s and 1990s, maintained high rates of structural mobility, but suffered in other aspects such as the decrease in the quality of opportunities of upward mobility, as well as the increasing inequality of opportunity by class origins. The article concludes with a discussion of future avenues of research for social mobility studies in Mexico.Résumé : La récession des années 1980 et la subséquente restructuration économique des années 1990 a causé un impact profond sur la société mexicaine. Néanmoins, ses conséquences sur la mobilité sociale n’ont été entièrement explorées qu’à la fin des années 1990, quand une série d’études empiriques a dévoilé des continuités et des changements dans les modèles de mobilité. Le but de cet article est d’analyser les tendances de la mobilité sociale inter générationnelle. Le débat porte sur quatre découvertes: la continuité de taux élevés d’ascension dans l’échelle sociale ; la réduction des entrées monétaires associée à une mobilité occupationnelle plus importante ; la rigidité croissante des taux relatifs à la mobilité occupationnelle ; et la totale conformité du cas mexicain au modèle type de fluidité sociale d’Erickson et Golthorpe. L’image qui émerge de ces résultats décrit une société qui, malgré les effets négatifs de la récession économique et les réformes structurelles des années 1980 et 1990, maintient de hauts indices de mobilité structurelle, mais qui paie les conséquences d’autres aspects tels que la baisse de la qualité des opportunités d’ascension dans l’échelle sociale, ainsi que l’augmentation de l’inégalité d’opportunités données par la classe d’origine. L’article conclut par une discus- sion sur les futures voies de recherche possibles pour affiner les études sur la mobilité sociale au Mexique.

Abstract:
Este texto describe las trayectorias de migración de los inmigrantes indígenas que laboran en el mercado de trabajo agrícola transnacional instalado en la frontera norte de México. Ubicados en la región del Valle de San Quintín, en el estado de Baja California, se adopta una perspectiva biográfica para el análisis de la experiencia de migración y trabajo de los individuos en un mercado laboral enfocado a la producción de hortalizas para el mercado internacional. Consideramos que la interrelación de varias dinámicas de movilidad –regional, interna e internacional– se pueden observar a través de la historia de movilidad, trabajo y asentamiento de los indígenas jornaleros distinguidos en cohortes generacionales para su análisis. Dicha interrelación parte de cambios en los patrones de movilidad y residencia de los grupos indígenas asentados en los sitios de trabajo, configurando así las nuevas geografías de los territorios étnicos en el país.Abstract: This text describes the different paths of migration of Indian immigrants working in the agricultural labor market transnational installed on Mexico Northern border. Adopting a biographical approach to the analysis of migration experience and work of individuals working in a market focused on the production of vegetables for the international market. The interplay between internal and international migrations is examined through the history of mobility, work and settlement of indigenous laborers along generational cohort lines. Such interplay can be explained by taking into account indigenous groups’ shifting patterns of residential mobility and settlement in new places of work, which in turn has led to the creation of new ethnic geographies throughout the country.Résumé : Ce texte décrit les différentes trajectoires migratoires des immigrés Indiens qui s’intègrent au marché du travail agricole transnational de la frontière nord du Mexique. Depuis la région de la vallée de San Quintin, en Basse-Californie, l’analyse a pour fondement une perspective biographique des expériences de migration et de travail des individus qui s’insèrent dans le secteur de la production de fleurs pour le marché international. La correspondance entre les divers types de dynamiques migratoires –régionale, interne et internationale– peut être observée au travers des histoires de mobilité, travail et installation des Indiens journaliers, population qui sera répartie en cohortes générationnelles pour l’analyse. Cette correspondance a pour point de départ les changements observés dans les formes de mobilité et d’installation des groupes indiens qui se sont établis sur les lieux de travail, conformant la nouvelle géographie des territoires ethniques dans le pays.

Abstract:
Anomalous urban mobility pattern refers to abnormal human mobility flow in a city. Anomalous urban mobility pattern detection is important in the study of urban mobility. In this paper, a framework is proposed to identify anomalous urban mobility patterns based on taxi GPS trajectories and Point of Interest (POI) data. In the framework, functional regions are first generated based on the distribution of POIs by the DBSCAN clustering algorithm. A Weighted Term Frequency-Inverse Document Frequency (WTF-IDF) method is proposed to identify function values in each region. Then, the Origin-Destination (OD) of trips between functional regions is extracted from GPS trajectories to detect anomalous urban mobility patterns. Mobility vectors are established for each time interval based on the OD of trips and are classified into clusters by the mean shift algorithm. Abnormal urban mobility patterns are identified by processing the mobility vectors. A case study in the city of Wuhan, China, is conducted; the experimental results show that the proposed method can effectively identify daily and hourly anomalous urban mobility patterns.

Abstract:
The novel coronavirus disease (COVID-19) pandemic has impacted every facet of society. One of the non-pharmacological measures to contain the COVID-19 infection is social distancing. Federal, state, and local governments have placed multiple executive orders for human mobility reduction to slow down the spread of COVID-19. This paper uses geotagged tweets data to reveal the spatiotemporal human mobility patterns during this COVID-19 pandemic in New York City. With New York City open data, human mobility pattern changes were detected by different categories of land use, including residential, parks, transportation facilities, and workplaces. This study further compares human mobility patterns by land use types based on an open social media platform (Twitter) and the human mobility patterns revealed by Google Community Mobility Report cell phone location, indicating that in some applications, open-access social media data can generate similar results to private data. The results of this study can be further used for human mobility analysis and the battle against COVID-19.

Abstract:
Urban mobility is known to have a relevant impact on work related car accidents especially during commuting. It is characterized by highly dynamic spatial–temporal variability. There are open questions about the size of this phenomenon; its spatial, temporal, and demographic characteristics; and driving mechanisms. A case study is here presented for the city of Rome, Italy. High-resolution population presence and demographic data, derived from mobile phone traffic, were used. Hourly profiles of a defined mobility factor (NPM) were calculated for a gridded domain during working days and cluster analyzed to obtain mean diurnal NPM mobility patterns. Age distributions of the population were calculated from demographic data to get insight in the type of population involved in mobility, and spatially linked with the mobility patterns. Census data about production units and their employees were related with the classified NPM mobility patterns. Seven different NPM mobility patterns were identified and mapped over the study area. The mobility slightly deviates from the census-based demography (0.15 on average, in a range of 0 to 1). The number of employees per 100 inhabitants was found to be the main driving mechanism of mobility. Finally, contributions of people employed in different economic macrocategories were assigned to each mobility time-pattern. Results provide a deeper knowledge of urban dynamics and their driving mechanisms in Rome.

Abstract:
Dans cette thèse j'envisage une approche originale de gestion des requêtes comme un processus traitant des événements (par exemple l'entrée dans une zone) liés aux déplacements des objets sur une représentation discrète de l'espace. Une requête se présente alors comme une séquence d'événements élémentaires donnés explicitement ou non. Nous introduisons les patterns de mobilité comme des expressions décrivant de telles séquences d'événements. Nous avons étudié essentiellement deux aspects dans ce cadre : comparaison et agrégation de trajectoires d'objets mobiles, avec prise en compte éventuellement d'un espace multi-échelle ; classification en ligne de trajectoires mises à jour continuellement par des outils GPS. Pour chacun des aspects abordés, nous proposons un modèle et une technique d'évaluation s'appuyant sur des algorithmes de recherche de patterns. Un prototype valide nos optimisations
In this thesis I investigate an original approach, namely the management of queries as a process relying on events (for instance, an object enters a zone) related to the moves of objects over a discrete representation of the underlying space. A query is thus a sequence of primitive events. We introduce mobility patterns as expressions describing such sequences of events. In the present paper we examine specifically the following aspects of this framework : comparison and aggregation of moving objects trajectories, with respect to, eventually, a multi-scale map ; on-line classification of trajectories continuously provided by GPS-like devices. For each aspect, we propose a model and an evaluation technique based on pattern-matching algorithms. A prototype validates our optimizations

Abstract:
Les sociologues s’accordent pour constater l’émergence de nouveaux rapports au temps, mais débattent des marges de manœuvre différenciées dont disposent les individus face à ces phénomènes. L’hypothèse que la vitesse de déplacement puisse être un levier est confortée par les études montrant que nos sociétés ont maîtrisé l’espace-temps grâce à l’amélioration des transports d’information et de marchandises. Cependant, peu de travaux empiriques abordent le sujet à l’échelle de l’individu. Cette thèse, qui repose sur une combinaison de méthodes qualitatives et quantitatives, a pour objectif de compléter ces recherches à travers l’étude des modes de transport utilisés et des pratiques spatiales quotidiennes en Île-de-France. Cette approche micro-sociale montre que l’augmentation du nombre et de la durée des activités hors du domicile n’est pas corrélée à une hausse des vitesses, mais à une diminution des distances parcourues pour se rendre à certaines activités. Ceci s’explique par les logiques de localisation des activités des individus. Pour celles auxquelles ils accordent de la valeur, ils maximisent la qualité de la destination, ce qui passe par l’utilisation de modes motorisés rapides. Pour les activités secondaires, ils minimisent leur temps de trajet en les localisant à proximité d’activités structurantes, ce qui induit l’usage de modes plus lents. Comme l’articulation entre ces deux logiques est plus aisée dans Paris qu’en banlieue, l’adoption d’un rythme de vie plus élevé et d’une planification plus souple y est facilitée. Plus que l’accès à la vitesse, ce sont les territoires de résidence qui induisent des disparités dans les marges de manœuvre face au temps
Times studies agree on the fact that our society is currently undergoing changes in terms of pace of life, but debates arise as to the uniformity of such changes within the population and individuals’ scope of action in the face of said phenomena. Given that society as a whole mastered time and space through the rise of transport speed, one is tempted to assume that it is also the case on the individual level. However, few empirical studies have taken it upon themselves to analyze the impact of speed in daily mobility on individuals’ pace of life. Using a combination of statistical analysis and in-depth interviews, this thesis aims at providing supplementary insight into the topic by analyzing transport modes and mobility patterns of inhabitants of the Greater Paris region. Through this micro-social analysis, we show that the more out-of-home activities people do, the lower their average speed in the course of a day is, whilst the average distance to a destination also decreases. This can be explained by the way they choose their destinations. For activities which are meaningful to them, they maximize the utility of their destination by using fast transport modes. For ancillary activities, they minimize travel time by locating them in the direct vicinity of their high-value activities, which prompts the use of slower modes. Finally, we show that the combination of these two rationales is easier in the center than in the suburbs, thus facilitating a high pace of life and more improvised schedules in the former. Hence, more than access to speed, it is residential location which induces disparities between people in their ability to deal with time demands

Abstract:
Ce travail s’inscrit dans le contexte d’un accroissement des populations dans les espaces peu denses et l’accroissement des distances domicile-travail (Hubert 2009). Cette conjonction de facteurs laissait supposer une non-durabilité notamment en raison des mobilités présumées accrues (DATAR 2003). Pour apporter une contribution à cette interrogation, nous avons, à l’ide de la Base Permanente des Equipements, examiné l’accessibilité à différents services de soins, et, en contre-points, à une piscine, une banque et une école de conduite. Nous avons ensuite examiné les schèmes de mobilité grâce aux données de l’Enquête Nationale Transports et Déplacements. Nous relativisons l’influence du territoire sur les comportements de mobilité. Après avoir présenté des explications possibles, nous proposons des pistes de politiques publiques
This thesis has been prepared in view of the increasing share of the population living in low-density areas, and the related increase in commuting distances (Hubert 2009). The result of the interplay between these factors may well be interpreted as an unsustainable development path, especially due to the supposedly increased level of mobility (DATAR 2003). To contribute to the discussion on these topics, this thesis examines the accessibility of various social services and other facilities, using data from the French facilities database. It then analyzes mobility patterns within the sample population using data of the French national travel survey. The analysis shows a weak influence of space characteristics on mobility behaviours. Following a discussion of possible explanations for the findings, the thesis offers potential directions for public policy to address these issues

Abstract:
Les intergiciels sont aujourd'hui incontournables lorsqu'il s'agit de développer des applications réparties. Chaque conception requiert des outils adaptés et performants. De plus, leur contexte de déploiement nécessite des mécanismes particuliers afin de s'y adapter. Pour cela, les intergiciels proposent des modèles de programmation et de communication différents, fournissant des moyens de communication efficaces dans certaines situations. En mobilité, l'interopérabilité devient inévitable, et le contexte varie. Cette thèse traite des impératifs d'un intergiciel en mobilité. Nous proposons ainsi une approche multi-modèles, basée sur les travaux actuels dans ce domaine, et présentant des concepts novateurs. Cette approche se compose d'un modèle de programmation générique et d'une combinaison de modèles de communication. Des politiques d'adaptation définissent les règles de combinaison des modèles en fonction d'observations du contexte, et des mécanismes d'adaptation dynamique permettent de prendre en compte en temps réelle contexte, et de reconfigurer le système pendant son exécution. Nous avons validé notre approche au travers d'une application concrète aux problèmes engendrés par l'utilisation d'un proxy Internet à bord des trains: le développement d'un greffon multi-modèles a illustré et justifié notre approche, et l'évaluation de ce greffon a montré les bénéfices de celle-ci face aux changements de contexte. Nous avons également conçu et développé notre infrastructure logicielle multi-modèles, proposant tous les concepts cités, et permettant ainsi de profiter des bénéfices de notre approche multi-modèles
The middlewares are nowadays unavoidable when developing dlstributed applications. Every design needs adapted and efficient· tools. ln addition, their context of deployment needs special mechanisms in order to adapt to it. To do so, the middlewares offer different programming and communication models, supplying efficient ways to communicate in some situations. ln mobility, interoperability becomes unavoidable, and the context changes. This thesis deals with the requirements of a middleware in mobility. We thus propose a multi-model approach, based on the current works in this domain, and presenting innovative concepts. This approach is composed by a generic programming model and by a combination of communication models. Adaptation policies define the rules of combination of models, regarding context observations and dynamic adaptation mechanisms allow to handle the context in realtime, and to reconfigure the system when it is running. Our approach has been validated through a concrete application to problems caused by the use of an embedded Intemet proxy in trains: the design and development of a mufti-model graft iIIustrated and justified our approach, and the evaluation of this graft demonstrated the benefits of this approach via-a-vis the changes of context. We also designed and developed our multi-model software infrastructure, proposing ail these concepts, and thus allowing to benefit from our multi-model approach

Abstract:
L'étude des comportements de mobilité est une thématique très peu investie dans les villes d'Afrique subsaharienne. Ces villes sont caractérisées par une croissance urbaine fulgurante avec comme corollaire un étalement spatial, des densités démographiques très élevées et une crise du secteur des transports dominé par les opérateurs artisanaux. Ces dynamiques, qui sont à l'origine de déséquilibres spatiaux, font que l'accès aux aménités urbaines devient très difficile pour les catégories de population les plus pauvres. A Dakar, les options d'aménagement ségrégationnistes prises par les autorités coloniales, l'inefficacité des instruments classiques de planification urbaine ainsi que la dérégulation du marché du foncier et de l'immobilier ont été à la base d'une dynamique de différenciation socio-spatiale. Ce travail de recherche, en faisant usage des méthodes d'analyse multidimensionnelle (Analyse en Composante Principale et Classification Ascendante Hiérarchique) et en se basant sur des enquêtes « ménages-déplacements » originales, se donne pour objectif d'analyser la dynamique ségrégative à Dakar et d'éclairer les liens existants entre la localisation résidentielle des ménages et les comportements de mobilité des individus dans un contexte urbain très changeant
The study of mobility behavior has not been well investigated in Sub-Saharan cities. These cities are characterized by rapid urban growth resulting in sprawl space, very high population densities and a crisis in transport sector which is dominated by craft operators. These dynamics, which are at the origin of spatial imbalances mean that access to urban amenities becomes very difficult for the poorest categories of the population. In Dakar, segregationist territorial management options taken in the past by colonial authorities, the ineffectiveness of traditional instruments of urban planning as well as disregulation of land market and real estate, have created a dynamic socio-spatial differentiation. This research project, by using multivariate analysis methods (Principal Component Analysis and Hierarchical Cluster Analysis) is based on original household travel surveys. Our objective is to analyze the dynamics of socio-spatial segregation in Dakar and illuminate the links between residential location and household mobility behavior in a changeable urban context

Abstract:
Le domaine de recherche de la mobilité urbaine vise l'observation et la conception des déplacements humains dans un environnement urbain, dont les informations aident à la prise de décision et à la résolution de problèmes dans le cadre des politiques publiques. De nombreux experts - pas nécessairement spécialistes des transports - doivent traiter des données urbaines plus ou moins standardisées pour en extraire des connaissances synthétiques et facilement exploitables. De ce fait, les agences de transport public mènent couramment des enquêtes de déplacements pour recueillir des informations sur les déplacements quotidiens de la population sur un territoire donné, dont les jeux de données résultant sont larges et complexes en requierant une analyse qui croise les dimensions spatiales, temporelles, thématiques et socio-économiques pour permettre de découvrir les schémas spatio-temporels de la mobilité quotidienne. Dans ce contexte, la visualisation d'informations est une approche appropriée pour soutenir l'analyse des données de mobilité urbaine, puisque les analystes n'ont pas à apprendre des méthodes sophistiquées pour interpréter les visualisations de données qui viennent renforcer leur cognition et permettent la découverte d'aperçus non structurés dans les données.Ainsi, nous proposons un cadre de visualisation pour aider à l'analyse de la mobilité urbaine à travers des indicateurs décrivant des objets d'intérêt complémentaires au sein des données qui permettent d'aborder trois catégories de questions sous-jacentes au phénomène de la mobilité urbaine. Une première question est de savoir comment les habitants d'un territoire se déplacent au quotidien et quels processus d'échanges entre les lieux cela génère, ce qui l'on peut analyser par l'exploration des quantités, des modalités, de la direction et de la variation des flux et des déplacements en fonction des différents aspects socio-économiques des individus et des types d'espaces. Une deuxième question concerne la variation temporelle de la présence de la population sur un territoire, qui permet de comprendre l'utilisation de différents ``sours-espaces'' en tenant compte des caractéristiques socio-économiques des personnes qui s'y rendent et des activités qu'elles y exercent. La troisième question cherche à expliquer le besoin de déplacement des individus à travers l'ordre temporel des déplacements et des activités des individus (aussi nommés ``trajectoires quotidiennes'') dans le contexte spatial du territoire.Nous proposons un cadre visuel à l'aide de la dérivation et l'exploration visuelle d'indicateurs décrivant le territoire, les flux et les déplacements, et les trajectoires quotidiennes, sur de multiples granularités spatio-temporelles et attributs thématiques. Notre interface de visualisation permet de disperser les représentations visuelles sur de multiples tableaux de bords analytiques, permettant aux utilisateurs de personnaliser l'agencement spatial des visualisations et les indicateurs de manière significative en fonction de l'analyse en cours. De plus, nous proposons une interaction basée sur le mouvement, qui repose sur l'inclinaison d'une tablette et qui permet d'explorer la variation temporelle des indicateurs en tirant parti d'une entrée tactile et tangible. La conception de notre approche de visualisation a suivi un processus d'évaluation interactif qui comprend des évaluations successives auprès des utilisateurs visant à affiner un prototype afin d'atteindre la performance et la satisfaction de l'utilisateur
The research field of urban mobility aims at the observation and design of human trips within an urban environment, which information supports decision-making and problem solving within public policies. In this context, there are many experts -- not necessarily transportation specialists -- that need to handle more or less standardized urban data to extract synthetic and easily exploitable knowledge. Hence, public transportation agencies commonly conduct trip-based surveys to collect information about day-to-day travel of the population within a particular territory (i.e. where and when we travel), resulting in large and complex datasets which analysis requires crossing spatial, temporal, thematic and socioeconomic dimensions to enable discoveries of daily urban mobility patterns. This way, information visualization is a suitable approach to support the analysis of urban mobility data, since analysts do not have to learn sophisticated methods to interpret the data visualizations that come to reinforce their cognition and enable the discovery of unstructured insights within the data.Thereby, we propose a visualization framework to assist the analysis of urban mobility through indicators describing complementary objects of interest within the data that allow to address three categories of questions underlying the urban mobility phenomenon. A first question seeks to understand the daily traveling routine of a population and the resulting processes of exchange between places, which can be studied through the exploration of amounts, modalities, direction, and variation of travel flows and trips according to different socioeconomic aspects of individuals and land types. A second questioning concerns the temporal variation of population presence throughout a territory, which allows to understand the use of distinct locations by taking into account the socioeconomic characteristics of the people visiting it and the activities they carry out there. The third question seeks to explain the individuals' need of traveling by studying the temporal ordering of trips and activities of individuals (i.e. daily trajectories) within the spatial context of the territory.Our framework supports the derivation and visual exploration of indicators describing the territory, travel flows and trips, and daily trajectories, over multiple spatio-temporal resolutions and thematic attributes. Our visualization interface allows to disperse visual representations over multiple analytical displays, enabling users to customize the spatial arrangement of visualizations and indicators in meaningful ways according to the ongoing analysis. Furthermore, we propose a movement-based interaction based on the tilting of a tablet that allows to explore the temporal variation of indicators leveraging tactile and tangible input. The conception of our visualization approach followed an interactive evaluation process that consists of successive user-based evaluations aiming to refine a prototype in order to achieve user performance and satisfaction

Abstract:
Cette thèse cherche à analyser les dynamiques résidentielles des populations immigrées et issues de l’immigration en France et leur situation face au logement. S’appuyant sur deux grandes bases de données, l’Echantillon Démographique Permanent (INSEE) et l’enquête Trajectoires et Origines (INED/INSEE), qui comptent parmi les rares bases de données en France qui permettent d’identifier les immigrés et leurs descendants à travers le temps (1990-2008), cette recherche comporte trois grands volets empiriques. En premier lieu, je propose un panorama des situations résidentielles des immigrés et de leurs descendants, en focalisant sur les caractéristiques des zones urbaines où ces groupes sont concentrés, leur statut d’occupation du logement, ainsi que la manière dont ces différentes dimensions résidentielles s’articulent. Deuxièmement, tirant profit de la dimension longitudinale des données, l’analyse porte sur la mobilité résidentielle de ces groupes, en traçant leurs trajectoires dans les quartiers et dans le logement. Finalement, je mène une analyse intergénérationnelle des inégalités résidentielles afin de déterminer à quel point les individus « héritent » les positions spatiales de leurs parents. L’analyse porte une attention particulière aux déterminants individuels et contextuels des trajectoires afin de mieux saisir les mécanismes qui structurent les inégalités face au logement et dans l’espace
My dissertation provides a comprehensive analysis of the neighborhood and housing outcomes of immigrants and natives in France. I draw on two large data sets, L’échantillon démographique permanent (INSEE) and Trajectoires et origines (INED/INSEE), which provide rare information about first and second generation immigrants, combine individual and contextual-level variables, and span several dates of observation (1990-2008). Drawing on classical theoretical approaches to immigrants’ spatial incorporation (spatial assimilation, place stratification), as well as insights from the social stratification and neighborhood effects literature, the analysis is rooted in a multidimensional, longitudinal and intergenerational approach to residential inequalities. First, I use a variety of indicators of the composition of neighborhoods (i.e. share of immigrants, co-ethnics, low-income households, the unemployment rate) in addition to housing tenure to explore associations between various dimensions of residential outcomes. Second, using longitudinal data and panel modelling techniques, the analysis captures patterns and determinants of residential mobility, transitions in neighborhoods, access to homeownership and moves in and out of the public housing sector. Finally, contributing to recent empirical work on the intergenerational reproduction of context, I seek to assess the extent to which residential situations are transmitted between parents and their children. The analysis seeks throughout to document the effects of individual factors (nativity, immigrant origin, socioeconomic status) and contextual factors (municipality and departmental characteristics) on shaping residential inequalities

Abstract:
The recent rise of services and networks that rely on human mobility has prompted the need for tools that detect our patterns of visits to locations and encounters with other individuals. The widespread popularity of location- and encounter-aware mobile phones has given us a wealth of empirical mobility data and enabled many novel applications that benefit from automated detection of an individual’s mobility patterns. This thesis explores the presence and character of periodic patterns in the visits and encounters of human individuals. Novel tools for extracting and analysing periodic mobility patterns are proposed and evaluated on real-world data. We investigate these patterns in a range of datasets, including visits to public transport stations on a metropolitan scale, university campus WLAN access point transitions, online location-sharing service checkins, and Bluetooth encounters among university students. The methods developed in this thesis are designed for decentralised implementation to enable their real-world deployment. Analysing an individual’s visit and encounter events is a challenging problem since the data are often highly sparse. In order to study visit patterns we propose a novel inter-event interval (IEI) analysis approach, which is inspired by neural coding techniques. The resulting measure, IEI-irregularity, quantifies the weekly periodic patterns of an individual’s visits to a location. To detect encounter patterns we propose and compare methods based on IEI analysis and periodic subgraph mining. In particular, we introduce the novel concept of a periodic encounter community; that is, a collection of individuals that share the same periodic encounter pattern. The decentralised algorithms we develop for periodic encounter community detection are of particular relevance to human-based opportunistic communication networks. We explore these communities in terms of their opportunistic content sharing performance. Our findings show that periodic patterns are a prominent feature of human mobility and that these patterns are algorithmically detectable.

Abstract:
Because of the internal mobility, rigid origami structures have great potential in engineering applications. In this research, a kinematic model of the rigid origami pattern is proposed based on the assembly of spherical 4R linkages. To ensure the rigid origami pattern with mobility one, the kinematic and geometric compatibility conditions of the kinematic model are derived. Four types of flat rigid origami patterns are obtained, including three existing types as well as a novel one called the supplementary type. To testify and display the mobile processes of the patterns, their simulation models are built accordingly.

Abstract:
The scope of combining two wettability regions is to impact the droplet dynamic behaviors, manipulate the droplets’ mobility and enhance condensation heat transfer. Hydrophobic-hydrophilic hybrid patterns can promote the heat transfer, droplet-renewal frequency and enhance the droplets’ removal during condensation. With regard of condensation on hybrid surfaces, the geometry of the patterns has a significant influence on droplets departure frequency and heat transfer performance. Therefore, different patterns geometries (circle, ellipse, and diamond) have been developed on horizontal copper tubes at atmospheric pressure. All the patterns have the same size, and the same identical gap as well between the adjacent patterns. Results show that the diamond hybrid surface has the best performance compared with ellipse, circles hybrid surfaces at the same pattern area with same neighbor gap between two patterns and complete dropwise However, the circle and ellipse hybrid surfaces outperform lower performance compared to complete dropwise surface. The heat transfer rate for the diamond hybrid surface is 15% higher than complete dropwise surface when the gap is 0.5mm. This study clearly demonstrated the effect of pattern’s geometry regarding maximum condensation heat transfer rate and droplet departure frequency.

Abstract:
The research question is if an increase in pandemics corresponds with significant changes in mobility (supported by the public stay-at-home orders and willing decrease of movements) by the spheres of economic activities (parks (leisure time spending), grocery stores, workplaces, pharmacies, transportation stations, retail, recreation, and home) in the Czech Republic. The additional research question is if this pattern correlates with a high decrease in salaries and employment. This paper aims to answer these research questions. This research applies the graphical analysis and fixed-effects regression methods for high-frequency data for answering these questions. The main result is that an increase in the number of infected people significantly decreases human mobility and increases their visits to pharmacies and staying at homes. At the same time, the government support measures can be effective, because there is no huge drop in salaries and employment in the Czech Regions. This pattern contradicts the expectations based on the US patterns. The output of the regression analysis is that 2-5 thousand new infections a day can paralyze mobility in the entire region.

Abstract:
Resch patterns have a great potential to be utilized in many engineering applications, as they can be folded into curved profiles from planar sheets. They are rigid foldable but with a large number of degrees of freedom (DOF) when there are many units tessellating in the patterns, which constrains the applications due to the difficulty in control the motion symmetrically. In this paper, in order to achieve the single mobility for a limited number of triangular Resch pattern units, the thick-panel technique is employed at each vertex to reduce the DOF to one. Then the compatibility among all the vertices has to be satisfied by the systematical kinematic analysis on the geometric parameters of the Resch pattern and panel thickness. Eventually, two design schemes are obtained to form the one DOF origami structure with doubly-curved intermediate folding configurations, which could be further tessellated into a large pattern for various engineering applications.

First, we characterize a dataset consisting of more than 200,000 user check-ins in the Foursquare social network, inferring important patterns in human mobility. Second, we use factorial design to quantify the importance of several types of contextual information in human mobility prediction. Our results show that the proximity of the users possible next check-in to his or her home and work location are the most important factors (among the ones we analyzed) to be used by mobility prediction models.

Abstract:
Modular origami is a type of origami where multiple pieces of paper are folded into modules, and these modules are then interlocked with each other forming an assembly. Some of them turn out to be capable of large scale shape transformation, making them ideal to create metamaterials with tuned mechanical properties. In this paper, we carry out a fundamental research on 2D modular origami assemblies using mathematical tiling and patterns and mechanism analysis, which leads to the development of various patterns consisting of interconnected quadrilateral modules. Due to the existence of 4R linkages within the patterns, they become transformable, and can be compactly packaged. Moreover, by the introduction of paired modules, we are able to adjust the expansion ratio of the pattern. Additionally, we also show that transformable patterns with higher mobility exist for other polygonal modules. Our findings provide more design flexibility to achieve truly programmable metamaterials.

Full text
Abstract:
This study analyzes mobility patterns during the COVID-19 pandemic for eight large Latin American cities. Indicators of mobility by socioeconomic status (SES) are generated by combining georeferenced mobile phone information with granular census data. Before the pandemic, a strong positive association between SES and mobility is documented. With the arrival of the pandemic, in most cases, a negative association between mobility and SES emerges. This new pattern is explained by a notably stronger reduction in mobility by high-SES individuals. A comparison of mobility for SES decile 1 vs decile 10 shows that, on average, the reduction is 75% larger in the case of decile 10. According to estimated lasso models, an indicator of government restrictions provides a parsimonious description of these heterogeneous responses. These estimations point to noticeable similarities in the patterns observed across cities. We also explore how the median distance traveled changed for individuals that travel at least 1 km (the intensive margin). We find that the reduction in mobility in this indicator was larger for high-SES individuals compared to low-SES individuals in six out of eight cities analyzed. The evidence is consistent with asymmetries in the feasibility of working from home and in the ability to smooth consumption under temporary income shocks.

Abstract:
Local and regional planners struggle to keep up with rapid changes in mobility patterns. This exploratory research is framed with the overarching goal of asking if and how geo-social network data (GSND), in this case, Twitter data, can be used to understand and explain commuting and non-commuting travel patterns. The research project set out to determine whether GSND may be used to augment US Census LODES data beyond commuting trips and whether it may serve as a short-term substitute for commuting trips. It turns out that the reverse is true and the common practice of employing LODES data to extrapolate to overall traffic demand is indeed justified. This means that expensive and rarely comprehensive surveys are now only needed to capture trip purposes. Regardless of trip purpose (e.g., shopping, regular recreational activities, dropping kids at school), the LODES data is an excellent predictor of overall road segment loads.

Full text
Abstract:
The urban population of Africa, the fastest urbanizing continent, has increased from 19% to 39% in the past 50 years, and the number of urban dwellers is projected to reach 770 million by 2030. However, while rapid urbanization has increased mobility and created a subsequent growth in demand for public transport in cities, this has not been met by the provision of adequate and sustainable infrastructure and services. The majority of low-income residents and the urban poor still lack access to adequate transport services and rely on non-motorized and public transport, which is often informal and characterized by poor service delivery. Lack of access to transport services limits access to opportunities that aren’t in the proximity of residential areas, such as education, healthcare, and employment. The urban public transport sector not only faces the challenge of poor service provision, but also of gender inequality. Research shows that, in the existing urban transport systems, there are significant differences in the travel patterns of and modes of transport used by women and men, and that these differences are associated with their roles and responsibilities in society. Moreover, the differences in travel patterns are characterized by unequal access to transport facilities and services. Women are generally underrepresented in the sector, in both its operation and decision-making. Women’s mobility needs and patterns are rarely integrated into transport infrastructure design and services and female users are often victims of harassment and assault. As cities rapidly expand, meeting the transport needs of their growing populations while paying attention to gender-differentiated mobility patterns is a prerequisite to achieving sustainability, livability and inclusivity. Gender mainstreaming in urban public transport is therefore a critical issue, but one which is under-researched in East Africa. This research explores gender issues in public transport in East Africa, focusing in particular on women’s inclusion in both public transport systems and transport policy decision-making processes and using case studies from three cities: Nairobi, Kampala and Dar es Salaam.
