Riskfyllda aktivitetsutrymmen? : En studie av två barn med utländsk bakgrund bosatta i miljöer med skilda socioekonomiska förutsättningar

Cárdenas, Pulgar, Camila, Natalia January 2013 (has links)
This study has as an objective to compare and evaluate the living conditions of two immigrant children residing in different places in Sweden. Given that immigrants often are looked upon as a social and physical vulnerable group in relation to disadvantageous socioeconomic conditions the children's lives were analyzed in relation to four public health objects. By using Runkeeper, GIS, Equipop data, time geographic material, telephone conversations and a web survey the children lives are analyzed within their activity spaces. The children formed their lives in different socioeconomic environments and adapted their lives after their conditions. The perspective on individual level can be put in contrast with studies based on society level. In relation to this the lives of these two children are observed as deviant because they showed a good health status in social and physical aspects. Some theories and hypothesis could be verified and some of these could be falsified. Keywords: Activity spaces, immigrant, socioeconomic conditions, health status.

Framtidens vinnare och förlorare i Östra Götaland? : Infrastruktur och tätortsutveckling i Östergötlands, Jönköpings och Kalmar län 2010-2020 / Winners and losers of the future in Eastern Götaland : Infrastructure and urban development in the County of Östergötland, Jönköping and Kalmar 2010-2020

Runnsjö, Joakim January 2010 (has links)
Syftet med uppsatsen är att studera möjlig utveckling av kommunerna och tätorterna i Jönköpings, Kalmar och Östergötlands län fram till 2020, med utblickar mot framtiden. Bakgrunden till uppsatsen är de diskussioner som förs i Sverige kring nya regionkommuner, där sammanslagningar av befintliga län ska ske. I denna process är Östra Götland ett förslag för de tre länen och därför är det av intresse att studera hur dessa kan utvecklas i framtiden. För denna analys har tidsgeografiska utgångspunkter kombinerats med Christallers centralortsteori för att skapa ett tredimensionellt tillgänglighetslandskap. Detta har sedan legat som en viktig förklaringsgrund för hur tätorter utvecklas. Resultatet av uppsatsen visar att de som lyckats locka till sig nya invånare kan delas upp i huvudsak i tre grupper; pendelorter med goda kommunikationer till andra orter, förorter med kort avstånd till regioncentra eller residensstäder (undantaget Östergötland där både Linköping och Norrköping är tillväxtorter). För de orter som inte lyckats utmärks dessa av att de ofta saknar goda kommunikationer och/eller befinner sig i en näringsomvandling, från dominerande basindustri till ett mer tjänstebaserat näringsliv. Framtidens vinnare blir troligen samma som idag och för den studerade regionen får Jönköping anses vara den största vinnaren, även om de andra länscentrana, Kalmar och Linköpipng/Norrköping, också är vinnare. Vissa frågetecken kring hur Norrköping klarar konkurrensen med Jönköping finns, på samma sätt som mellan Kalmar och Växjö, då en stark tillväxt i en ort kan få andra orter att stå tillbaka. / The purpose of the paper is to study the possible development of municipalities and urban areas in the county of Jönköping, Kalmar and Östergötland to 2020, with glimpses into the future. The background to the paper are discussions taking place in Sweden on a new regional division, where a merge of existing counties are about to happen. In this process is the forming of Eastern Götaland a proposal for the three counties and it is therefore of interest to study how these may evolve in the future. For this analysis, time-geographical bases combined with Christaller central place theory are used to create a three-dimensional landscape of accessibility. This has then been used as an starting point in the discussions about how urban areas evolve. The results of the paper shows that those who succeeded in attracting new residents can be divided mainly into three groups; commuter towns with good transport links to other places, suburbs whit short distances to a regional center or provincial capitals (except in Östergötland, where both Linköping and Norrköping are growth centers). For those which have not been able to this has often a lack of good communications and/or are in a business transformation, from primary industry to a more service-based economy. Tomorrow's winner will likely be the same as today, and in the studied region Jönköping may be considered as the biggest winner, though the other county towns, Kalmar and Linköping/Norrköping, also are winners. There are some uncertainties about how Norrköping stands in the competition with Jönköping, just as between Kalmar and Växjö,. A strong growth in one urban area may cause that the growth in other areas are reduced.

Espacer l'organisation : trajectoires d'un projet de diffusion de la science et de la technologie au Chili

Vásquez Donoso, Consuelo 08 1900 (has links)
Comprendre le mode d’existence de l’organisation est certainement l’un des plus grands défis que se sont donnés les chercheurs qui s’intéressent à ce domaine d’étude. La littérature nous présente ainsi plusieurs images, métaphores et perspectives qui, combinées, dressent un portrait hybride de ce type de collectif. Je propose, dans cette thèse, de reconnaître et exploiter ce caractère hybride de l’organisation en partant d’une réflexion centrée sur l'espace. En m’inspirant particulièrement des travaux de la géographe Doreen Massey (1999, 2005), le concept d'espace auquel je souscris est celui d’un espace ouvert et dynamique (qui incorpore le temps), basé sur une relationalité matérielle et hétérogène, supposant des acteurs humains et non humains en interaction. L'espace peut donc être compris comme la coexistence d’ontologies hétérogènes, ce que Massey (2005) nomme une coexistence de trajectoires comme stories-so-far. Il s’agit ici d’une vision performative de l’espace organisationnel qui est constitué dans la relation de trajectoires distinctes qui coexistent, se rencontrent, s’affectent, entrent en conflit ou coopèrent (Massey, 1999). Je postule que pour assurer une certaine continuité et cohérence dans la coexistence de trajectoires hétérogènes, un travail d’alignement et d’ordonnancement est mis à l’oeuvre, et ce, par le suivi d’une trajectoire principale — ce que je nomme une trajectoire scriptée. Suivre cette trajectoire permet ainsi à l’organisation de s’étendre, de se rendre présente dans le temps et dans l’espace, sans pour autant perdre son identité : to be here and there at the same time, now and then at the same place. À partir de cette définition de l’espace, je propose d’« espacer l’organisation », et plus particulièrement d’« espacer » Explora, un programme d’éducation non formelle du gouvernement du Chili visant la diffusion et la valorisation de la science et de la technologie. Cette proposition est double : elle renvoie aux pratiques d’espacements — des pratiques hybrides, collectives et situées — des agents organisationnels (dans ce cas, aux pratiques des agents d’Explora impliqués dans l’organisation d’un projet, celui de la Semaine de la science 2006),mais aussi à une pratique de recherche. « Espacer l’organisation » veut donc dire déployer ces espaces pleins, déplier l’organisation, accroître la série des simultanéités-successions pour ainsi créer plus d’espace-temps. / To understand the organization’s mode of being is certainly one of the most important challenges faced by researchers who are interested in this field of study. The literature presents several images, metaphors and perspectives which, combined, draw up a hybrid portrait of this type of collective. In this dissertation, I propose to recognize and exploit this hybrid character by starting from a reflection on space. Inspired especially by the work of the geographer Doreen Massey (1999, 2005), the concept of space to which I subscribe is that of an open and dynamic space (which incorporates time), based on a material and heterogeneous relationality, which supposes human and nonhuman actors in interaction. Space can thus be understood as the coexistence of heterogeneous ontologies, what Massey (2005) calls a “coexistence of trajectories as stories-so-far”. It is then a performative vision of organizational space which is constructed through the relation of distinct trajectories that coexist, meet, affect each other, enter in conflict or cooperate (Massey, 1999). I argue that to guarantee a certain form of continuity and coherence in the coexistence of heterogeneous trajectories, a work of alignment and ordering is put at work, and this, by the following-up of a main trajectory — what I call a scripted trajectory. By following this trajectory the organization can then extend itself, making itself present in time and space, without loosing its identity: it can be “here and there at the same time, now and then at the same place.” Starting from this definition of space, I propose to “space the organization,” and more specifically to “space” Explora, a non formal educational program of the Chilean government, which aims to diffuse and promote science and technology. Spacing an organization implies a double proposal: it refers to the spacing practices — hybrid, collective and situated practices — enacted by organizational agents (in this case, Explora’s agents implicated in the organization of a project, that of the Science week 2006), but also to a research practice. “Spacing the organization” consists of deploying these full spaces, unfolding the organization, and increasing the series of simultaneities-successions in order to create more space-time.

Home, Job and Space : Mapping and Modeling the Labor Market

Östh, John January 2007 (has links)
How does space affect individuals’ outcome on the labor market? And how do we measure it? Beyond the notion of the labor market as a system of supply and demand, lays a society of individuals and workplaces, whose relationships are undeniably complex. This thesis aims to shed some new light on how to investigate and analyze the complex labor market relationships from a spatial perspective. In this thesis, five self-contained articles describe the spatial relationship between individuals and workplaces. In the first article, the official delineation of local labor market areas is tested against the delineation of labor markets for different subgroups. Differences in the regionalization are discussed from the subgroups’ and municipals’ perspective. In the second article, two sources of bias in the computation of local labor market areas, and suggestions how to reduce them, are presented. In the third article the spatial mismatch hypothesis is tested and confirmed on a refugee population in Sweden. In articles four and five, a new model for the estimation of job accessibility is introduced and evaluated. The model, ELMO, is created to answer to the need for a new accessibility measure to be used in spatial mismatch related research. The usability of the model is validated through empirical tests, were the ELMO-model excels in comparison to the accessibility models it is tested against.

GIS-based Episode Reconstruction Using GPS Data for Activity Analysis and Route Choice Modeling / GIS-based Episode Reconstruction Using GPS Data

Dalumpines, Ron 26 September 2014 (has links)
Most transportation problems arise from individual travel decisions. In response, transportation researchers had been studying individual travel behavior – a growing trend that requires activity data at individual level. Global positioning systems (GPS) and geographical information systems (GIS) have been used to capture and process individual activity data, from determining activity locations to mapping routes to these locations. Potential applications of GPS data seem limitless but our tools and methods to make these data usable lags behind. In response to this need, this dissertation presents a GIS-based toolkit to automatically extract activity episodes from GPS data and derive information related to these episodes from additional data (e.g., road network, land use). The major emphasis of this dissertation is the development of a toolkit for extracting information associated with movements of individuals from GPS data. To be effective, the toolkit has been developed around three design principles: transferability, modularity, and scalability. Two substantive chapters focus on selected components of the toolkit (map-matching, mode detection); another for the entire toolkit. Final substantive chapter demonstrates the toolkit’s potential by comparing route choice models of work and shop trips using inputs generated by the toolkit. There are several tools and methods that capitalize on GPS data, developed within different problem domains. This dissertation contributes to that repository of tools and methods by presenting a suite of tools that can extract all possible information that can be derived from GPS data. Unlike existing tools cited in the transportation literature, the toolkit has been designed to be complete (covers preprocessing up to extracting route attributes), and can work with GPS data alone or in combination with additional data. Moreover, this dissertation contributes to our understanding of route choice decisions for work and shop trips by looking into the combined effects of route attributes and individual characteristics. / Dissertation / Doctor of Philosophy (PhD)
