Abstract:

The psychometric properties of a new high-level mobility outcome measure for Service Members (SMs) with traumatic lower limb loss called the Comprehensive High-level Activity Mobility Predictor (CHAMP) was developed in order objectively evaluate functional abilities and measure change in function throughout the rehabilitation process. The CHAMP was administered to a population of SMs with traumatic lower limb loss who were representative of those who have suffered limb loss in recent conflicts. In addition, a population of non-amputee Active Duty soldiers completed the CHAMP and provided normative data for high-level mobility and threshold levels of performance for those SMs with lower limb loss. A simple grading system, absent of floor and ceiling effects, generates a composite score providing a single numeric value representing the physical performance factors of high-level mobility in different plane of motion and under different conditions. The CHAMP was found to be a safe, reliable, valid, and responsive performance-based outcome measure of high-level mobility. It was found to have excellent interrater and test-retest reliability suggesting that it is a stable and repeatable measure of high-level mobility. Convergent construct validity and known group methods were utilized to establish the CHAMP as a valid measure of high-level mobility. Predictive models of CHAMP performance were established utilizing variables representing impairments of body structure and function and contextual factors by level of lower limb amputation. The CHAMP has the potential to be used for lower limb amputees throughout the rehabilitation process and could translate to the non-amputee population for assessment of high-level mobility capabilities.

Abstract:

The present study examines a Mobility Management measure called “test traveller project”, which aims at increasing the public transport modal share by offering free public transport tickets to those who often use their car for their daily commuting and trips. The existing literature consists of a rather limited number of cases and their scope is usually limited because only some of the main elements that influence one’s travel behaviour are considered in each study. Furthermore, literature is not unanimous in concluding that this measure can reduce car use. This work studies more than 50 cases in Sweden, and by employing the Theory of Planned Behaviour the effects of test traveller projects have been examined in an empirical case in the Swedish municipality of Botkyrka, located in the Stockholm metropolitan area. The findings underline that a test traveller project, despite its limitations, may be a valid and relatively simple tool available to public bodies and public transport companies for enticing a segment of car drivers to switch to public transport where it is a valid alternative. In fact, according to the literature, the major results achievable are around 20% of new public transport users among test travellers, whereas in Sweden 20% has been achieved by the first upper quartile of the projects. In particular, the effectiveness of a test traveller project is greater when combined or conducted in parallel with other measures such as improvements in the public transport offer and/or changes in the transport system aiming at disadvantaging car use. The case study of Botkyrka has confirmed that attitudes are the major influencing factor when making the transport mode choice. Further, it has confirmed that environmental concerns and the time passed from one’s residential relocation also play an important role. Habits seem to be less important, thus adhering to that literature whose authors argue that an external event (such as moving home) makes people reflect upon and rethink their travel habits. The case study in Botkyrka has empirically demonstrated how the project participants correct their beliefs and perceptions about public transport, sometimes in a positive way and sometimes in a negative way. An interesting finding is the existence of a new category of people living in the suburbs. Literature indicates that, in the same suburban context, individuals with suburban land use preferences tend to use the car more that individuals with urban land use preferences. In the case study of Botkyrka clearly emerged as a majority among the test traveller project participants a category of individuals who have a suburban land use preference but at the same time would like to use public transportation instead of their car and have high environmental concerns.

Abstract:

In order to be compliant with the Basel regulations, banks need to compute two probabilities of default (PDs): point-in-time (PIT) and through-the-cycle (TTC). The aim is to explain fluctuations in the rating system, which are expected to be affected by systematic and idiosyncratic factors. Being able to, in an objective manner, determine whether the rating system is taking the business cycle - i.e the systematic factors - into account when assigning a credit rating to an obligor is useful in order to evaluate PD-models. It is also necessary for banks in order to use their own risk parameters and models instead of standardized models, which is desirable for most banks as it could lower capital requirements. This thesis propose a new measure for the degree of PIT-ness. This measure aims to be especially useful when examining a low default portfolio. The proposed measure is built on a markovian approach of the credit rating system. In order to find a suitable measure for a low default portfolio, the proposed measure takes into account credit rating migrations, the seasonal component of the business cycle and time series analysis. An analysis were performed between two different credit portfolios in order to interpret results. The results demonstrated that the degree of PIT-ness was lower in a low default portfolio in comparison with a sampled portfolio which displayed a greater amount of rating migrations with a larger magnitude. The importance of considering relevant macroeconomic variables to represent the business cycle was mentioned amongst the most important factors to consider in order to receive reliable results given the proposed measure.
För att uppfylla Basel regelverken behöver banker beräkna två sannolikheter för fallissemang (PD): point-in-time (PIT) och through-the-cycle (TTC). Målet är att förklara fluktuationer i betygssystemet, som förväntas påverkas av systematiska och idiosynkratiska faktorer. Att på ett objektivt sätt kunna avgöra om betygssystemet tar hänsyn till affärscykeln - dvs de systematiska faktorerna - när man tilldelar en kredittagare ett kreditbetyg är användbart för att utvärdera PD-modeller. Detta är också nödvändigt för att banker ska få använda sina egna riskparametrar och modeller istället för standardiserade modeller, vilket är önskvärt för de flesta banker eftersom det kan sänka kapitalkraven. Denna avhandling föreslår ett nytt mått för att mäta graden av PIT-ness. Detta mått syftar till att vara särskilt användbart när man utvärderar en kreditportfölj med få fallissemang. Det föreslagna måttet är byggt på en Markov tillämpning på kreditbetygssystemet. För att hitta ett lämpligt mått för en kreditportfölj med få fallissemang, tar det föreslagna måttet hänsyn till kreditbetygsmigrationer, säsongskomponenten i affärscykeln och tidsserieanalys. En analys utfördes mellan två olika kreditportföljer för att tolka resultaten. Resultaten visade att graden av PIT-ness var lägre i en kreditportfölj med få fallissemang jämfört med en testportfölj som uppvisade en större mängd kreditbetygsmigrationer med en större magnitud. Vikten av att beakta relevanta makroekonomiska variabler för att representera affärscykeln nämndes bland de viktigaste faktorerna att beakta för att få tillförlitliga resultat givet det föreslagna måttet.

Abstract:

Research that addresses policy measures to increase the adoption of electric vehicles (EVs) has discussed government regulations such as California’s Zero Emission Vehicle (ZEV) or penalties on petroleum-based fuels. Relatively few articles have addressed policy measures designed to increase the adoption of EVs by incentives to influence car buyers’ voluntary behavior. This article examines the effects of such policy measures. Two of these attributes are monetary measures, two others are traffic regulations, and the other three are related to investments in charging infrastructure. Consumer preferences were assessed using a choice-based conjoint analysis on an individual basis by applying the hierarchical Bayes method. In addition, the Kano method was used to elicit consumer satisfaction. This not only enabled the identification of preferences but also why preferences were based on either features that were “must-haves” or on attributes that were not expected but were highly attractive and, thus, led to high satisfaction. The results of surveys conducted in 20 countries in 5 continents showed that the installation of a charging network on freeways is an absolute necessity. This was completely independent from the average mileage driven per day. High cash grants were appreciated as attractive; however, combinations of lower grants with charging facilities resulted in similar preference shares in market simulations for each country. The results may serve as initial guidance for policymakers and practitioners in improving their incentive programs for electric mobility.

ENGLISH ABSTRACT: Enterprise mobility is emerging as a megatrend in the business world. Numerous risks originate from using mobile devices for business-related tasks and most of these risks pose a significant security threat to organisations’ information. Organisations should therefore apply due care during the process of governing the significant enterprise mobility security risks to ensure an effective process to mitigate the impact of these risks. Information technology (IT) governance frameworks, -models and -standards can provide guidance during this governance process to address enterprise mobility security risks on a strategic level. Due to the existence of the IT gap these risks are not effectively governed on an operational level as the IT governance frameworks, -models and -standards do not provide enough practical guidance to govern these risks on a technical, operational level. This study provides organisations with practical, implementable guidance to apply during the process of governing these risks in order to address enterprise mobility security risks in an effective manner on both a strategic and an operational level. The guidance given to organisations by the IT governance frameworks, -models and -standards can, however, lead to the governance process being inefficient and costly. This study therefore provides an efficient and cost-effective solution, in the form of a short list of best practices, for the governance of enterprise mobility security risks on both a strategic and an operational level.
AFRIKAANSE OPSOMMING: Ondernemingsmobiliteit kom deesdae as ‘n megatendens in die besigheidswêreld te voorskyn. Talle risiko's ontstaan as gevolg van die gebruik van mobiele toestelle vir sake-verwante take en meeste van hierdie risiko's hou 'n beduidende sekuriteitsbedreiging vir organisasies se inligting in. Organisasies moet dus tydens die risikobestuursproses van wesenlike mobiliteit sekuriteitsrisiko’s die nodige sorg toepas om ‘n doeltreffende proses te verseker ten einde die impak van hierdie risiko’s te beperk. Informasie tegnologie (IT)- risikobestuurraamwerke, -modelle en -standaarde kan op ‘n strategiese vlak leiding gee tydens die risikobestuursproses waarin mobiliteit sekuriteitsrisiko’s aangespreek word. As gevolg van die IT-gaping wat bestaan, word hierdie risiko’s nie effektief op ‘n operasionele vlak bestuur nie aangesien die ITrisikobestuurraamwerke, -modelle en -standaarde nie die nodige praktiese leiding gee om hierdie risiko’s op ‘n tegniese, operasionele vlak te bestuur nie. Om te verseker dat organisasies mobiliteit sekuriteitsrisiko’s op ‘n effektiewe manier op beide ‘n strategiese en operasionele vlak bestuur, verskaf hierdie studie praktiese, implementeerbare leiding aan organisasies wat tydens die bestuursproses van hierdie risiko’s toegepas kan word. Die leiding aan organisasies, soos verskaf in die IT-risikobestuurraamwerke, - modelle en -standaarde, kan egter tot’n ondoeltreffende en duur risikobestuursproses lei. Hierdie studie bied dus 'n doeltreffende, koste-effektiewe oplossing, in die vorm van 'n kort lys van beste praktyke, vir die bestuur van die mobiliteit sekuriteitsrisiko’s op beide 'n strategiese en 'n operasionele vlak.

Abstract:

Transportation and mobility are important components in the organisation and structure of people´s daily activities, but the transport sector has considerable environmental impacts, e.g. greenhouse gas emissions and land use. Governance of the sector is difficult, as there is an ongoing a shift in governance structures away from hierarchical towards more collaborative governance. Given these challenges, it may be necessary to shift the focus from mobility to accessibility and to adopt a new paradigm in transport planning. This thesis critically investigates what a paradigm shift might mean for the Swedish national and municipal transport, housing and parking planning context and examines what a Social Practice Theory framework could contribute in analysing such a paradigm shift. This is done by investigating three different policies that are arguably in line with a shift in planning paradigms. All three policy measures open up decision making to different stakeholders or even citizens, reflecting a shift in governance, and all highlight the need to shift the focus from physical infrastructure to accessibility, through collaboration with a range of stakeholders. However, in each case, current conditions and practices render a transition more difficult. The Swedish Transport Administration (STA) states the importance of reducing the need to travel and of using existing infrastructure more efficiently, and stipulates that these types of measures should be considered before new infrastructure investments. However, the STA has a limited mandate to finance these measures, resulting in ambiguous signals and frustration among regional STA officials. This thesis shows that making the STA’s mandate more function-oriented would facilitate a transition in line with the sustainable mobility paradigm. Another policy measure discussed in the thesis is a shift from minimum parking requirements, where developers are required to build a minimum number of parking spaces, to flexible parking requirements, where the number of parking spaces provided depends on the local context and where other mobility services may replace the need for physical parking spaces. In this thesis, people who have bought apartments in developments with flexible parking requirements were surveyed in order to understand their practices and how they perceive and plan to use the mobility services provided. The feasibility of using a new parking management tool, Parking Benefit Districts, in a European context (Stockholm, Sweden) was assessed. In a Parking Benefit Districts system, parking charges are implemented, increased or extended to curb parking, with the revenues being returned to the area where the charges are imposed and with citizens, or other stakeholders, participating in decisions on how to use the revenues. The underlying intention is to increase acceptance of parking charges, as on-street parking charges may be deemed necessary by planners, but are unpopular among citizens and other stakeholders. This thesis shows that there are no legal barriers to implementing a Parking Benefit District programme in Sweden, but there are some limitations on how revenues can be used. Moreover, Sweden does not have this planning tradition and the programme may not be perceived as legitimate. Another important issue is equity and participation, e.g. it is important to consider who to include and how to include them. Overall, the policy measures studied involve a shift away from an infrastructure-centred to a people-centred approach. However, other planning practices and institutions may push in different directions. This thesis shows that a Social Practice Theory framework can be useful as a lens through which researchers and policymakers view possible changes needed to achieve a sustainable mobility paradigm.
Transport och mobilitet är viktiga komponenter i organiseringen och strukturen av människors dagliga aktiviteter. Transportsektorn ger emellertid upphov till stor miljöpåverkan, exempelvis växthusgasutsläpp och markanvändning. Governance av sektorn är komplicerad och det har skett ett skifte från en hierarkisk styrning mot en större delaktighet och samarbete mellan olika aktörer. Givet dessa utmaningar kan det finnas behov av att flytta fokus från att palnera för rörlighet till tillgänglighet samt att ändra planeringsparadigmer. Syftet med avhandlingen är dels att kritiskt undersöka vad ett paradigmskifte skulle kunna innebära i det svenska nationella och kommunala transport-, bostads- och parkeringsplaneringssammanhanget, dels att undersöka hur ett Social Practice Theory ramverk skulle kunna bidra till förståelsen av ett sådant paradigmskifte. För att göra detta har avhandlingen undersökt tre policys som är i linje med ett paradigmskifte. Alla policys som diskuteras i avhandlingen öppnar upp beslutsfattande för olika aktörer eller medborgare. Vidare lyfter alla diskuterade strategier fram behovet av att flytta fokus från fysisk infrastruktur till tillgänglighet och att samarbete mellan olika intressenter är nödvändigt. I varje fall finns dock förhållanden och praktiker som försvårar omställningen. Trafikverket framhåller exempelvis vikten av att minska behovet av att resa och av att använda befintlig infrastruktur mer effektivt, och de menar att dessa åtgärder bör övervägas innan nya infrastrukturinvesteringar. Samtidigt har Trafikverket begränsat mandat att finansiera dessa åtgärder, vilket ger upphov till tvetydiga signaler och frustration bland regionala planerare på Trafikverket. Papper I argumenterar för att ett mer funktionsorienterat mandat skulle kunna underlätta en ett paradigmskifte i linje med en ’sustainable mobility paradigm’. I paper II diskuteras en förändring från miniminorm för parkeringsplatser vid bostäder, där byggherrarna måste bygga minst ett visst antal parkeringsplatser, till flexibla parkeringstal, där antal parkeringsplatser som ska byggas beror på den lokala kontexten och där andra mobilitetstjänster kan ersätta behovet av parkeringsplatser. I detta paper studeras personer som har köpt lägenheter i flerbostadshus med flexibla parkeringstal. Målet är att förstå dessa människors praktiker och hur de använder och uppfattar de mobilitetstjänster som tillhandahålls. I papper III diskuteras möjligheten att använda ett nytt parkeringsverktyg, Parking Benefit Districts, i en europeisk kontext. Parkering Benefit Districts är ett koncept där parkeringsavgifter på gatan införs, höjs eller utökas. Intäkterna från parkeringsavgifterna återförs därefter till det område där de togs ut, och medborgare, eller andra intressenter i området, deltar sedan i beslutet om hur intäkterna ska användas. Syftet med denna åtgärd har traditionellt varit att öka acceptansen för parkeringsavgifter, eftersom parkeringsavgifter på gatan kan anses vara fördelaktiga av planerare, men impopulära bland medborgare och andra intressenter. Paper III nämner i analysen att det inte finns några legala hinder för att genomföra ett Parking Benefit District program i Sverige, men det finns vissa begränsningar för hur intäkterna kan användas. Planerare i Stockholms stad hävdar dock att Sverige inte har den här planeringstraditionen och påpekar att ett sådant åtgärd kanske inte uppfattas som legitim. En annan viktig fråga att diskutera är jämlikhet och deltagande. Det finns en risk att vissa grupper i samhället inte deltar i samma utsträckning och det är därför viktigt att överväga vem som ska involveras samt hur det ska ske. I slutet diskuteras resultaten i relation till forskningsfrågorna. Alla de studerade policys skiftar fokus från fysisk infrastruktur till människors behov. Samtidigt finns det andra planerings praktiker och institutioner som drar samhällsutvecklingen i motsatt riktning. I avhandlingen diskuteras även hur ett Social Practice ramverk kan hjälpa både forskare och beslutsfattare att se de förändringar som behövs för att nå en ’sustainable mobility paradigm’.

Abstract:

The goal of this study is to investigate the predictive ability of less data intensive but widely accepted methods to estimate mobility and reliability measures. Mobility is a relatively mature concept in the traffic engineering field. Therefore, many mobility measure estimation methods are already available and widely accepted among practitioners and researchers. However, each method has their inherent weakness, particularly when they are applied and compared with real-world data. For instances, Bureau of Public Roads (BPR) Curves are very popular in static route choice assignment, as part of demand forecasting models, but it is often criticized for underperforming in congested traffic conditions where demand exceeds capacity. This study applied five mobility estimation methods (BPR Curve, Akcelic Function, Florida State University (FSU) Regression Model, Queuing Theory, and Highway Capacity Manual (HCM) Facility Procedures) for different facility types (i.e. Freeway and Arterial) and time periods (AM Peak, Mid-Day, PM Peak). The study findings indicate that the methods were able to accurately predict mobility measures (e.g. speed and travel time) on freeways, particularly when there was no congestion and the volume was less than the capacity. In the presence of congestion, none of the mobility estimation methods predicted mobility measures closer to the real-world measure. However, compared with the other prediction models, the HCM procedure method was able to predict mobility measures better. On arterials, the mobility measure predictions were not close to the real-world measurements, not even in the uncongested periods (i.e. AM Peak and Mid-Day). However, the predictions are relatively better in the AM and Mid-Day periods that have lower volume/capacity ration compared to the PM Peak period. To estimate reliability measures, the study applied three products from the Second Strategic Highway Research Program (SHRP2) projects (Project Number L03, L07, and C11) to estimate three reliability measures; the 80th percentile travel time index, 90th percentile travel time index, and 95th percentile travel time index. A major distinction between mobility estimation process and reliability estimation process lies in the fact that mobility can be estimated for any particular day, but reliability estimation requires a full year of data. Inclusion of incident days and weather condition are another important consideration for reliability measurements. The study found that SHRP2 products predicted reliability measures reasonably well for freeways for all time periods (except C11 in the PM Peak). On arterials, the reliability predictions were not close to the real-world measure, although the differences were not as drastic as seen in the case of arterial mobility measures.

Abstract:

Les études portant sur les effets de l'environnement sur la santé ont essentiellement examiné les effets de l'environnement résidentiel. Cette approche a été critiquée pour son absence de prise en compte des environnements géographiques de vie non-résidentiels. L'objectif général de cette thèse est d'évaluer si la prise en compte des lieux d'activité dans lesquels les individus se déplacent et sont régulièrement exposés permet de mieux estimer l'impact de l'environnement sur la pratique de la marche récréative. Trois études transversales ont été conduites sur la seconde vague de la Cohorte RECORD. La première étude a permis d'identifier une typologie des comportements de mobilité individuels et les déterminants sociodémographiques de ces mobilités. Les résultats de la deuxième étude montrent que l'exposition à des caractéristiques environnementales facilitant la marche diffère entre le quartier de résidence, le quartier résidentiel perçu, et l'espace d'activité. L'erreur de mesure liée à la seule prise en compte de mesures d'exposition résidentielle varie en fonction des groupes socio-économiques et des degrés d'urbanisation de la résidence dans la région Île-de-France. Dans la troisième étude, une densité de destinations élevée, la présence de lacs ou de voies d'eau et un niveau d'éducation élevé du quartier sont associés à une augmentation de la pratique de la marche récréative. Cette thèse souligne l'importance de prendre en compte les environnements géographiques de vie résidentiels et non-résidentiels pour mieux approximer l'exposition environnementale réelle, et évaluer les effets de l'environnement sur les comportements de santé
Previous studies on place effect on health focused on the residential neighborhood. This approach was criticized for not considering non-residential geographic life environments. The overarching aim of this dissertation is to estimate whether accounting for people’s network of activity places and their resulting exposure allows improving the understanding of environmental influences on recreational walking behavior. Three cross sectional studies were conducted on the second wave of the RECORD Cohort Study. In the first study, I identified a typology of individuals’ patterns of mobility and related socio-demographic correlates. Results from the second study provide evidence that exposure to environmental characteristics supportive to walking highly differs between the residential neighborhood, the perceived residential neighborhood and the activity space. The measurement error resulting from the sole use of residential measures of exposure varies among SES groups and among categories of the degree of urbanicity of the residence. In the third empirical study a high density of destinations, the presence of a lake or waterway, and a high neighborhood education are associated with recreational walking. This dissertation strengthen the conceptual grounds and empirical evidence that accounting for both residential and non-residential geographical environments individual get exposed is required to better proxy the true environmental exposure, and to estimate environmental influences on health behaviors

Full text

Abstract:

Tracking activities during daily life and assessing movement parameters is essential for complementing the information gathered in confined environments such as clinical and physical activity laboratories for the assessment of mobility. Inertial measurement units (IMUs) are used as to monitor the motion of human movement for prolonged periods of time and without space limitations. The focus in this study was to provide a robust, low-cost and an unobtrusive solution for evaluating human motion using a single IMU. First part of the study focused on monitoring and classification of the daily life activities. A simple method that analyses the variations in signal was developed to distinguish two types of activity intervals: active and inactive. Neural classifier was used to classify active intervals; the angle with respect to gravity was used to classify inactive intervals. Second part of the study focused on extraction of gait parameters using a single inertial measurement unit (IMU) attached to the pelvis. Two complementary methods were proposed for gait parameters estimation. First method was a wavelet based method developed for the estimation of gait events. Second method was developed for estimating step and stride length during level walking using the estimations of the previous method. A special integration algorithm was extended to operate on each gait cycle using a specially designed Kalman filter. The developed methods were also applied on various scenarios. Activity monitoring method was used in a PRIN’07 project to assess the mobility levels of individuals living in a urban area. The same method was applied on volleyball players to analyze the fitness levels of them by monitoring their daily life activities. The methods proposed in these studies provided a simple, unobtrusive and low-cost solution for monitoring and assessing activities outside of controlled environments.

Urbana områden har formats efter den bilnorm som råder i modern tid. Detta har belastat miljön och medfört att städer idag står inför det stora arbetet att ställa om till hållbara samhällen. Hållbara mobilitetslösningar har blivit ett aktuellt ämne som följd av denna problematik. Viktiga aktörer i arbetet med åtgärder för hållbar urban mobilitet är fastighetsutvecklare. Syftet med studien är att undersöka fastighetsutvecklares roll i arbetet med hållbart resande vid uppbyggnaden av en ny stadsdel. Tre områden i Västra Hamnen i Malmö har bedömts relevanta och fungerar som fallstudier. Med hjälp av teorier kring ämnet hållbar urban mobilitet samt semistrukturerade intervjuer och dokumentanalys har frågeställningarna undersökts och diskuterats. Studiens slutsatser visar att fastighetsutvecklare har en betydande roll i implementeringen av hållbar mobilitet vid nybyggnation. Vidare identifieras parkeringsnormen som ett viktigt verktyg. Studien belyser vidare vikten av åtgärder för beteendeförändring, samt planering anpassad för målgrupp.
Urban areas are shaped after the existing automobile dependency in modern time. This has burdened the environment and resulted in a need for cities to evolve into sustainable places. Sustainable mobility measures have become an urgent matter as a result of this problem. An important actor in the work with mobility measures for a sustainable urban mobility are developers. The purpose of this study is to examine developers’ role in the work with sustainable travel when a new city area is under development. Three areas in the Western Harbour in Malmö have been deemed relevant as case studies. Theories about sustainable urban mobility together with semi-structured interviews and document analyses served to examine and discuss the formulated questions. The conclusions of the study show that developers have a prominent role in the implementation of sustainable mobility in new city areas. Furthermore, the parking standards are identified as an important tool. The study illuminates the importance of measures for behavioral changes as well as planning for a targeted group

Abstract:

För att öka bland annat trivsel och säkerhet inom ett bostadsområde är det av av stor fördel att anlägga bostadsparkering i utkanten och på sätt minska trafikflödet inom området. En sådan parkeringslösning förutsätter dock att viss markyta inom området avsätts för att kunna ställa upp sin bil under en kortare period för att hämta eller lämna passagerare samt lasta i eller ur gods. Detta kallas för att korttidsangöra. Examensarbetet har kartlagt hur korttidsangöring används samt undersökt om behovet att angöra påverkas av avstånd till parkering och socioekonomiska faktorer inom ett område.

Abstract:

The life expectancy of the elderly population is expected to increase with 22 % by 2050. As one grows older, the body starts to deteriorate, which can lead to a higher risk for diseases and accidents. During recent years shoulder surgeries have increased dramatically, and to assess the shoulder function the most common technique is the use of camera-based motion capture systems. However, this is very time consuming and does not completely represent the real shoulder performance. Therefore, this study was aimed to validate a new technique, the force range monitor (FRM). Thirteen volunteers participated in this study, which was divided into two sessions. Session one included abduction and flexion strength measurements using the FRM, as well as six mobility measurements with the inertial measurement unit (IMU) of the FRM. The second session was conducted in the same manner, with the addition of the Vicon system (motion capture system). In this study a control session for FRM and the Vicon system was also performed for abduction and flexion movements with two participants, where the placement of the IMU was modified. As indicated by the results, FRM and the Vicon system do not measure the same parameters. Even if the FRM does not measure the same shoulder joint angles as the Vicon System, the FRM can still be of clinical importance when evaluating position deviation during strength and mobility measurements. Moreover, the FRM had a high repeatability for a number of participants, and most of the mobility measurements presented a distinct patterns for various activities. Hence, it can be concluded that the FRM is a potential technique to evaluate shoulder strength and mobility.

Abstract:

Objective: There is emerging evidence that exercise may modify disease progression and improve function in a number of neurodegenerative diseases, but this has not been systematically studied in Huntington.s disease (HD). The purpose of this study was to evaluate feasibility, acceptability and benefits of an exercise programme in people with HD. Methods: Using a randomised controlled trial design, 25 participants with manifest HD were allocated to either intervention (home-based exercise; n=13) or control (usual care;n=12) groups. Participants were assessed at baseline and eight weeks later. Eleven participants from the exercise and 10 from the control group completed the intervention study. The primary outcome was gait variability (stride time coefficient of variation (CV)). Secondary outcomes included other measures of gait, disease-specific motor scale and measures of balance, muscle strength, mobility and community walking, functional performance in ADL and quality of life. These measures were included to reflect a range of physical impairments and activity limitations seen in people with HD. Analysis of covariance was used to compare follow-up scores across groups after adjustment for differences at baseline. Effect sizes were calculated for outcome measures based on differences in change scores between groups. Process interviews were conducted at the end of the study to determine acceptability of the intervention to participants. Cross sectional investigation of outcome measures was undertaken initially to investigate discriminant and concurrent validity as well as test re-test reliability and minimal detectable change (MDC95) along the broad spectrum of the disease. Baseline data from 25 participants with manifest HD (who went on to participate in the intervention), in addition to data from 17 individuals with pre-manifest HD and 25 healthy controls were analysed. This data was of use in interpreting the results from the interventional study. In particular, the MDC95 data helped in determining of whether any statistical significant changes due to the intervention are clinically meaningful. Results: Measures of gait variability, some measures of balance, community walking and measures of functional performance in ADL were able to distinguish between people with manifest HD and pre-manifest HD as well as between people with pre-manifest HD and healthy controls suggesting good discriminant validity. All these outcomes had also good concurrent validity with a disease specific motor score. The test re-tests reliability scores for the majority of the outcomes were high and the MDC95 scores were low, suggesting that the individual variability on these outcomes were low. Adherence rates to the exercise programme were high (78.8% of participants reported completion of at least 78% of the prescribed sessions). Participants in the intervention group demonstrated significant improvement in stride time CV (95% CI (-11.5, -0.6))based on complete case analysis. Significant differences between groups were also observed in the disease-specific motor scale and in measures of balance, mobility,community walking and functional performance in ADL, but not muscle strength and health-related quality of life. Effect sizes were large (>0.8) for the majority of the outcomes. The magnitude of the change as a result of the exercise intervention exceeded the calculated MDC95 values for some of the outcomes, which suggest that most of the observed changes are clinically meaningful. Qualitative feedback from the participants who completed the exercise programme suggested high levels of acceptability with positive impact on general health and mobility. Participants identified barriers and facilitators that affected performing the exercises at home and described management strategies that helped adherence to the exercise programme. Conclusions: This study was the first systematic trial to demonstrate that a short-term structured exercise programme is acceptable and can be safely delivered in a home environment; achieve good adherence; and positively affect body function and activity in people with HD. The sensitivity of the outcomes as determined in the cross-sectional study, to mobility deficits the in pre-manifest HD group is important. These outcomes has the potential to be used in future studies of exercise interventions in the premanifest stage which aim to target such deficits early in the disease life cycle, before they begin to impact on a person.s ability to participate in the community. Overall the data presented from this study provides a platform for further investigations to extend these findings about the role of exercise and physical activity in people with HD. Larger and more detailed studies are needed to replicate findings from this study in othercontexts and variations in dose.

Abstract:

This study examined the impact of involuntary mobility on the academic achievement of tenth grade students in a Central Florida school district. Students of involuntary mobility were selected as the result of new attendance boundaries due to new high school construction. Students were compared against non-mobile peers at schools of like demographics (i.e. poverty level and ethnicity). Mobility status (involuntary or no mobility) was the independent variable. The dependent variable, academic achievement, was measured by students' tenth grade developmental scale scores in reading and mathematics on the Florida Comprehensive Assessment Test. Students' ninth grade test scores were used as a covariate to control for students’ prior achievement and isolate the impact of mobility. Additional subgroups (minority and poverty) were compared to determine if involuntary mobility had a more significant impact on these groups. Finally, a hierarchical linear regression was used to determine if a model for reading and mathematics could be used to predict future academic performance for students of involuntary mobility. Findings showed consistently there was no statistically significant difference in the achievement performance among groups or subgroups and the subject tests of reading and/or mathematics with one exception. There was a statistically significant difference in mathematics achievement in the all students group when comparing those students of involuntary mobility with students of stability. Students of mobility actually indicated a modest level of higher achievement than non-mobile peers. The hierarchical linear model was found to be marginally significant for predicting achievement among involuntary mobility students in the area of mathematics, but not necessarily in reading. Future research recommendations include broadening the research to additional grade-levels. This research only considered the impact of achievement on high school students. Future research should consider similar impact on students at both the elementary and/or middle school levels. Qualitative measures would provide additional information, particularly the perceptions and experiences that stakeholders have throughout the involuntary mobility process. Other at-risk subgroups, particularly those of residential mobility and/or previous retention, provide additional considerations that would add to this body of research. Finally, involuntary mobility as the result of school closings would provide additional insight as this factor often has public negative perceptions.

Abstract:

An already calibrated and validated VISSIM model for Simplified Dynamic Lane Merge System (SDLMS) in accordance with the real life work zone was modified with a VSL through Vehicle Actuated Programming (VAP) code. Three different logics were coded each for VSL alone, early SDLMS+VSL and late SDLMS+VSL. All these logics were fine tuned with several test runs before finalizing it for the final simulation. It is found through the simulation of above mentioned scenarios that for low and medium volume levels (V0500, V1000 and V1500), there is no significant difference between the Maintenance of Traffic (MOT) plans for mean throughputs. However, for higher volume levels (V2000 and V2500), late SDLMS with and without VSL produced higher mean throughputs for all compliance rates and truck percentages except when the demand volume was 2,500 vph and compliance of 60%, where it produces the significantly lower mean throughputs. In terms of travel time through the work zone, results indicated that there is no significant difference between MOT types for demand levels of V0500 and V1000 when compliance is 40% or less but for compliance of 60% and more, only demand volume level that is not significantly different from other MOT types is V0500. This study revealed that VSL increases travel time through the work zone. This might be due to non-compliant vehicles that follow the compliant vehicle ahead unless they find a sufficient gap in adjacent lane to pass the compliant vehicle. It is also found out that VSL makes the system safer at higher volumes (2,000 vph and 2,500 vph). This was observed through safety surrogate measures selected for this study.; Another outcome of this study is that the addition of VSL to the dynamic merge systems helps in improving the overall safety of the system by lowering speed variances and deceleration means of the vehicles travelling through the work zone. The passage of traffic through the work zone is made safer when a speed control is integrated to a dynamic merge system. It can be inferred from the simulation results that integrated SDLMS and VSL systems have better performance in terms of traffic mobility and safety than existing individual controls and also show that the integrated SDLMS and VSL system has more potential than each individual systems.; In recent years, there has been a considerable increase in the amount of construction work on the U.S. national highways. Most of the work undertaken is the reconstruction and rehabilitation of the existing transportation networks. Work zones in the United States are likely to increase in number, duration and length due to emphasis on repair and highway reconstruction as a significant portion of all federal-aid highway funds are now geared toward highway rehabilitation. The challenge of mobility is particularly acute in work zone areas as road repair and construction intensifies traffic issues and concentrates them in specific locations and at specific times. Due to the capacity drop, which is the result of lane closure in work zone area, congestion will occur with a high traffic demand. The congestion increases number and severity of traffic conflicts which raise the potential for accidents; furthermore traffic operational properties of roadway in work zone area become worse. Intelligent Transportation System (ITS) technologies have been developed and are being deployed to improve the safety and mobility of traffic in and around work zones. In several states in the US, the use of Dynamic Merge Controls also known as Dynamic Lane Merge (DLM) system has been initiated to enhance traffic safety and to improve traffic flow in work zone areas. The DLM usually takes two forms; dynamic early merge and dynamic late merge. The use of variable speed limit (VSL) systems at work zones is also one of those measures. VSL systems improve safety by helping the driver in determining the maximum speed that drivers should travel. Besides adding improvement to safety, they are also expected to improve mobility at the work zones.; The main goal of this study is to evaluate the safety and operational effectiveness of the dynamic merge systems i.e. the dynamic early lane merge and dynamic late lane merge, in the presence of VSL system. More specifically, the VISSIM model is utilized to simulate a two-to-one lane configuration when one out of the two lanes in the work zone is closed for traffic. Six different scenarios were adopted to assess the effectiveness of these scenarios under different traffic demand volumes and different drivers' compliance rates to the messages displayed by the systems. These scenarios are; bullet] Work Zone without VSL and without SDLMS or the current Motorist Awareness System (MAS) bullet] Work Zone with VSL and without SDLMS bullet] Work Zone with VSL and Early SDLMS bullet] Work Zone with VSL and Late SDLMS bullet] Work Zone with early SDLMS and without VSL bullet] Work Zone with early SDLMS and without VSL

Abstract:

This dissertation investigates the impacts of the COVID-19 pandemic on mobility considering a study case of Bologna by analysing readily available data of public transportation (buses), vehicle and cyclist flows collected from manual passenger counts, automatic traffic and cyclist counters respectively. The timeline of the study was split into four phases covering periods before the pandemic occurred, during the first lockdown, immediately after lockdown restrictions were lifted and post-lockdown stages. Additional data was obtained from the open access data provided by Moovit app on the usage of mobility options during the timeframe of the study. Analysis on data for the modes considered included weekly trip comparisons from 2019 and 2020, comparisons of usage during phases of the study and modal comparisons. Measures (policy and infrastructure wise) enacted by local government authorities in Bologna prior and during this pandemic are also examined considering the role of sustainability and resilience building. Results obtained from the case study are compared to other metropolitan cities to identify some similarities and differences to establish conclusions with recommendations suggested. It is found that Bologna experienced an overall mobility reduction of 76%, 18% and 0.5% during the phases 2, 3 and 4 respectively. Additionally, cycling was the only mode to surpass its initial levels from Phase 1 in Phase 3, showing 31% and 40% increases in usage in Phases 3 and 4. Public transportation (buses) was the most impacted during Phase 2 experiencing about 90% decrease in usage. Private transport (vehicle use) showed the most resilience reaching figures (101.4%) in Phase 4 almost identical to that recorded before the lockdown. This study reveals that withstanding the impacts of the COVID-19 pandemic on transport choices, active travel has a significant role to play in the choice of users in future mobility.

Abstract:

La recherche d'une mobilité plus durable constitue aujourd'hui un souci partagé chez les responsables des grandes villes du monde, qui doivent alléger la pression des transports sur l'espace (congestion), la qualité de vie (nuisances, accidents), l'environnement (émissions de CO2) en maintenant leur capacité de développement et en préservant ou améliorant leur cohésion sociale. C'est le cas sur nos terrains d'étude, qui sont l'Île-de-France, Shanghai et Taipei. Cette recherche de durabilité s'inscrit dans un contexte historique, géographique et culturel, qui prédétermine l'état de la mobilité et de ses évolutions sur les territoires. Notre première partie est consacrée à l'analyse de la mobilité et de ses dynamiques sur ces trois terrains. Les moyens d'aller vers cette durabilité peuvent reposer sur le progrès technologique, la planification urbaine, la tarification des systèmes et les évolutions d'usage des modes. Des transferts des modes individuels vers le transport public sont généralement considérés comme souhaitables, et le développement de transport intermodal est une des conditions de ce développement. Notre travail distingue fortement le bus et le rail dans les modes collectifs, et le vélo, les deux-roues motorisés et la voiture dans les modes individuels. Il porte sur les perspectives de transfert modal et le rôle potentiel de l'intermodalité. Ces perspectives dépendent de trois types de coûts : les coûts qualifiés d'" externes ", qui motivent le besoin de plus de durabilité ; les coûts pour l'usager, qui déterminent largement ses comportements ; les coûts d'investissement et d'exploitation des systèmes, dont une part souvent importante est financée par les pouvoirs publics et les impôts. La caractérisation théorique, la modélisation et l'évaluation empirique de ces coûts pour les trois terrains d'étude sont l'objet de la partie II. La comparaison des coûts par voyageur-km entre modes individuels et modes collectifs fait apparaître qu'aucun ne peut être meilleur que les autres sur les trois postes de coûts, et que les différences dépendent de plus des types de déplacements (longueurs, origines-destinations, etc.). La partie III est de nature plus prospective. Elle présente d'une part les schémas de développement des territoires et des transports adoptés par les responsables de ces territoires. Elle explore d'autre part les capacités à aller vers une mobilité plus durable à partir des comparaisons issues de nos territoires et des évaluations de coûts menées dans la partie II. Deux politiques importantes sont explorées : les politiques de stationnement et les politiques de tarification des transport publics ; Les travaux présentés dans ce mémoire de thèse ont pour but de contribuer au développement de ce modèle d'évaluation des coûts de déplacement et d'une méthode de diagnostic permettant de proposer des visions des transports dans le cadre de développement durable et d'orienter les politiques de déplacement vers plus de durabilité et d'intermodalité.

Abstract:

Cette thèse étudie les déterminants des choix de localisation des étudiants en mobilité internationale et des étudiants étrangers. Une analyse globale s’intéresse aux déterminants des migrations estudiantines vers les pays de l’OCDE. En utilisant des méthodes d’estimation présentes dans les travaux sur le commerce international (régressions de Poisson), il apparaît, en plus des déterminants traditionnels liés aux migrations de travailleurs, que la qualité de l’enseignement dans les pays de destinations soit un déterminant fort des migrations estudiantines. Par ailleurs, un effet réseau, par qualification, a été mis en évidence. Une analyse des déterminants appliquée au cas français confirme les résultats de l’étude précédente et met en évidence un effet réseau par âge ainsi qu’une forte sensibilité aux coûts supportés par les étudiants pendant leurs études (prix de l’immobilier…).Cette thèse évalue aussi les impacts macroéconomiques des migrations estudiantines sur l’économie française grâce à un modèle d’équilibre général calculable à générations imbriquées. Accueillir des étudiants internationaux pour les former représente un coût mais ce coût peut être compensé par un accroissement du stock de capital humain de l’économie se traduisant par un taux de croissance du PIB plus important. Néanmoins, l’ampleur des gains dépend de la taille des flux d’étudiants ainsi que de la part des étudiants formés en France qui intègrera le marché du travail français, une fois leurs études accomplies (taux de rétention). Les migrations estudiantines ont aussi un impact sur le financement du régime de retraite français en modifiant le ratio inactifs/actifs
This thesis investigates the determinants of the localisation of international students and international students. A comprehensive analysis focuses on the determinants of student migration to OECD countries. Using estimation methods present in the literature on international trade (Poisson regressions), it appears, in addition to traditional determinants of migration of workers, that the quality of education in the destination countries is a key determinant of student migrations. Furthermore, a network effect (diaspora effect), by qualification, has been demonstrated. An analysis of determinants applied to the French case confirms the results of the previous study and highlights a network effect by age and a strong sensitivity to the costs borne by students during their studies (rental prices…).This thesis also evaluates the macroeconomic impacts of student migration on the French economy through a computable general equilibrium model with overlapping generations. Educating international students represents a cost but this cost may be offset by an increase in the stock of human capital in the economy resulting in a larger growth rate of the GDP. However, the magnitude of gains depends on the size of the students flows and on the share of the students educated in France who will integrate the French labor market, once their studies are completed (retention rate). The students migrations also have an impact on the financing of French retirement system by modifying the inactive/active ratio

Abstract:

Natürliche Niederungsgebiete wirken als effektive Phosphor Senke. Landwirtschaftliche Nutzung und Drainage führt zur Transformation zu Phosphor Quellen. Dem Spreewald, ein Feuchtgebiet und seiner Funktionsweise als Phosphor Quelle oder –Senke, kommt im Einzugsgebiet der Spree eine wichtige Rolle zu. Die vorhandenen Kenntnisse der Phosphor Umsatzprozesse und des Phosphor Austausches zwischen den Flächen und dem Fließgewässernetz sind jedoch gering. Praktikable Ansätze zur Beschreibung des Phosphor Austauschverhaltens von Nährstoffen in den ausgedehnten Polderregionen liegen nicht vor. Anhand hydrologischer, geohydraulischer und biogeochemischer Prozessuntersuchungen in einer Polderlandschaft mit typischer Stauhaltung konnten die Phosphor Freisetzungs- und Retentionsprozesse ausgewiesen werden. Unter Nutzung verschiedener Modellansätze (geohydraulische Modellierung, Stofftransportmodellierung und Statistische Modelle) und der Berechnung von Phosphor Prozessraten werden horizontale und vertikale Phosphor Fluxe in den Flächen-Wasser Übergangszonen quantifiziert. Die Ergebnisse gehen in ein Phosphor Bilanzmodell ein, das die P-Quellen und Senkenfunktion von Polder Teilflächen (überstaut, genutzt) und des gesamten Polders in Monatsschritten abbildet. Die biogeochemischen Phosphor Umsatzprozesse sowie der horizontale und vertikale Transport werden wesentlich von den hydrologischen und den klimatischen Bedingungen gesteuert. Sie stellen die primären Einflussgrößen der P Senken oder -Quellenfunktion dar. Im Polder wird die Phosphor Netto Freisetzung der genutzten Bereiche durch eine hohe Phosphor Netto Retention in den überstauten Flächen abgemindert. Szenario Untersuchungen zeigen, dass sinkende Grabenwasserstände zu einer erheblichen Erhöhung der Phosphor Emissionen aus dem Grundwasserpfad führen. Ansteigende Phosphor Fluxe bei sinkenden Wasserständen legen ein zunehmendes Eutrophierungsrisiko in den Gräben sowie für unterhalb gelegene aquatische Systeme nahe.
Natural wetlands effectively retain phosphorus. Agricultural cultivation and drainage by ditches transform them to phosphorus sources. In the Spree catchment, the Spreewald, a large scaled lowland has a strategic importance operating as a phosphorus sink or phosphorus source. Anyhow, knowledge of its phosphorus turnover processes and the phosphorus exchange behavior between the plain and the river and ditch network are marginal. Practicable approaches to reproduce the phosphorus exchange behavior in its typical polder areas are missing. Based on process investigations in a polder area with typical weir regulation, phosphorus retention and remobilization processes are characterized. Combining different model approaches (groundwater modeling, matter transport modeling and statistical models) and calculating process rates, the horizontal and vertical phosphor fluxes in the water soil/sediment transition zones are quantified. The outcomes are used as input data for a phosphorus balance model reproducing the phosphorus source and sink character of used and rewetted polder areas and for the whole polder in monthly time steps. Results from process and transport investigations point out that biogeochemical turnover processes and horizontal or vertical phosphorus transport are driven by hydrological and climatological conditions. Net phosphorus release found in the extensive used polder areas is counteracted by significant net phosphorus retention in the rewetted parts. Scenario analyses identify decreasing ditch water levels to cause a considerable increase of phosphorus emissions from the groundwater pathway. Consequently, the increasing phosphorus fluxes at decreasing water levels provoke a growing risk for eutrophication in the ditches but also in the downstream aquatic systems.

Full text

Abstract:

Bilen har länge varit en central del av många människors vardag där många städer är uppbyggda efter bilens funktion. Idag vill många kommuner minska bilanvändandet och ersätta bilresor som inte är nödvändiga med andra mer miljövänliga färdmedel såsom kollektiv- och cykeltrafik. Många kommuner vill dessutom förtäta stadens centrum och då ses ofta markparkering i attraktiva lägen som ett problem eftersom det tar upp mycket värdefull yta.Syftet med detta examensarbete är att beskriva hur olika kommuner hanterar parkeringsfrågan för att få en helhetsbild av hur Sverige behandlar frågan. De flesta kommuner arbetar idag med flexibla parkeringstal där byggherren ges möjlighet att utföra så kallade mobilitetsåtgärder, till exempel bilpool, som kan ge en reducering av antalet parkeringar som behöver anläggas vid nyexploatering. Detta system är relativt nytt och eftersom många kommuner numera tänker arbeta efter denna modell framöver fokuserar examensarbetet på detta. Det gällande lagstödet som reglerar parkeringar är från 80-talet och då kan åsikterna ha varit annorlunda angående bilen och parkeringar än vad de är idag. Det finns ingen tydlig vägledning för hur kommunerna skall hantera parkeringsfrågan då lagen är öppet formulerad och det inte finns många vägledande rättsfall vilket gör det svårt för kommunerna att ha en gemensam strategi.Från resultaten av granskningen kan verkan och långsiktigheten för mobilitetsåtgärderna i vissa fall ifrågasättas eftersom det finns osäkerhet kring hur de faktiskt påverkar efterfrågan på parkeringar i framtiden. Det är därför av vikt att arbetet med flexibla parkeringstal kan utvärderas och följas upp. Här kan kommunerna ta hjälp av varandra för att få större möjligheter att utvärdera fler fall där flexibla parkeringstal använts.Lagens krav är uppfyllt så länge kommunerna utgår från att uppfylla behovet av parkeringar på lång sikt. Om ett parkeringstal skall sänkas ska åtgärder som långsiktigt påverkar parkeringsbehovet genomföras till exempel förbättrad kollektivtrafik. Det finns däremot vissa fall där kommuner sätter för låga parkeringstal med syfte att minska bilanvändandet utan att egentligen ha påverkat efterfrågan på parkeringar.
The car has for a long time been a central part of people’s everyday life and many cities are constructed around the car. A lot of the municipalities nowadays want to reduce the use of the car and replace those journeys with other more environmentally friendly options as public transport and bicycles. They also often want to build cities that are denser and in doing that, parking spaces on the ground become a problem in attractive locations because they take up a lot of space.The purpose of this thesis is to describe how different municipalities deal with the parking issue in order to get a picture of how the issue is dealt with in Sweden. Most of the municipalities are now working with flexible parking numbers where the developer or real estate owner is given the opportunity to use mobility measures in order to reduce the amount of parking spaces they have to build. This system is relatively new and whereas most of the municipalities are planning to use this model, this thesis focuses on this matter.The current law that regulate parking derives from the eighties and at that time the general opinion about cars and the matter of parking might have differed from the general view today. There is no distinct guidance for how the municipalities should handle the parking issue since the law is open to interpretations and there are not many court cases that handle the matter.After studying 18 different municipalities it can be concluded that the longevity of the mobility measures can be questioned in some cases. This is because there can be uncertainties about how the measures actually affect the demand of parking in the future. Therefore, it is important that the work with flexible parking numbers is to be evaluated and followed up. The municipalities can also learn from and help each other to get more cases where flexible parking numbers have been used to evaluate.Using flexible parking numbers applies with the current law as long as the municipalities start with fulfilling the need for parking spaces in the long term. If the parking number is to be lowered, measures that affects the need for parking spaces is to be performed, for example better public transport. There are however some cases where municipalities set lower parking numbers in order to reduce car journeys without actually influencing the demand for parking spaces.

Thèse réalisée en cotutelle entre l'Université de Montréal et l'Université Pierre et Marie Curie, Paris 06, Sorbonne Universités.
Contexte : Les études portant sur les effets de l’environnement sur la santé ont essentiellement examiné les effets de l’environnement résidentiel. Cette approche a été critiquée pour son absence de prise en compte des environnements géographiques de vie non-résidentiels (c.-à-d. le travail, l’école, les lieux récréatifs et sociaux, etc.). Alors que la mobilité est un déterminant clé de l’exposition, peu d’études ont examiné les mobilités quotidiennes pour évaluer les effets du milieu sur la santé. Objectifs : L’objectif général de cette thèse est d’évaluer si la prise en compte des lieux d’activité dans lesquels les individus se déplacent et sont régulièrement exposés permet de mieux estimer l’impact de l’environnement sur la pratique de la marche récréative. Les objectifs spécifiques de la thèse sont : i) identifier les différents types de comportement spatiaux des individus vivants en région Île-de-France et leurs déterminants sociodémographiques ; ii) évaluer si l’exposition à des facteurs environnementaux facilitant la marche diffère en fonction de la définition géographique de la zone d’exposition et varie en fonction du niveau socio-économique et de la localisation de la résidence dans la région Île-de-France ; iii) évaluer les caractéristiques environnementales, résidentielles et non-résidentielles, associées à la pratique de la marche récréative. Méthodes : Trois études transversales ont été conduites sur la seconde vague de la Cohorte RECORD (Residential Environment and CORonary heart Disease). Les lieux d’activité réguliers des participants, ainsi que la délimitation de leur quartier résidentiel perçu ont été collectés grâce à l’application VERITAS (Visualization and Evaluation of Regular Individual Travel destinations and Activity Spaces). Résultats : La première étude a permis d’identifier une typologie des comportements de mobilité individuels caractérisés par : i) la taille de l’espace d’activité, ii) l’élongation de l’espace d’activité, iii) le centrage de l’espace d’activité sur le quartier de résidence, iv) le volume d’activités, et v) les types d’activités réalisées. Le statut socio-économique et la localisation de la résidence dans l’agglomération parisienne sont apparus comme de forts déterminants du comportement spatial. Les résultats de la deuxième étude montrent que l’exposition à des caractéristiques environnementales facilitant la marche diffère entre le quartier de résidence, le quartier résidentiel perçu, et l’espace d’activité. L’erreur de mesure liée à la seule prise en compte de mesures d’exposition résidentielle varie en fonction des groupes socio-économiques et des degrés d’urbanisation de la résidence dans la région Île-de-France. Dans la troisième étude, une densité de destinations élevée, la présence de lacs ou de voies d’eau et un niveau d’éducation élevé du quartier sont associés à une augmentation de la pratique de la marche récréative. Enfin, cette étude montre une forte influence des caractéristiques environnementales autour de la résidence et des lieux d’activité récréatifs sur la pratique de la marche récréative. Conclusion : Cette thèse souligne l’importance de prendre en compte les environnements géographiques de vie résidentiels et non-résidentiels pour i) mieux approximer l’exposition environnementale réelle, ii) évaluer les effets de l’environnement sur les comportements de santé. Afin d’approfondir les mécanismes par lesquels l’environnement influence la pratique de l’activité physique, il apparait pertinent d’examiner conjointement où les individus se déplacent, mais également ce que les individus font, en termes de types d’activité et de contraintes liées aux activités réalisées. Identifier quels lieux d’activité ont le plus d’influence sur la pratique de l’activité physique contribue à cibler des contextes géographiques prioritaires pour les interventions en promotion de la santé.
Background: Previous studies on place effect on health focused on the residential neighborhood. This approach was criticized for not considering non-residential geographic life environments. While mobility is a key determinant of exposure, few studies accounted for daily mobility to evaluate environmental effects on health. Purpose: The overarching aim of this dissertation is to estimate whether accounting for people’s network of activity places and their resulting exposure allows improving the understanding of environmental influences on recreational walking behavior. The specific objectives are: i) to identify types of spatial behavior of individuals living in the Ile-de-France region and their socio-demographic correlates; ii) to assess whether the exposure to supportive walking environments differs depending on the geographic definition of the exposure area and varies by the socioeconomic status and the degree of urbanicity; iii) to evaluate which residential and non-residential neighborhood characteristics are associated with recreational walking. Methods: Three cross sectional studies were conducted on the second wave of the RECORD Cohort Study (Residential Environment and CORonary heart Disease). Information on participants’ regular activity places and perceived residential neighborhood were collected through the VERITAS application (Visualization and Evaluation of Regular Individual Travel destinations and Activity Spaces). Result: In the first study, I identified a typology of individuals’ patterns of mobility characterized by: i) the size of the activity space, ii) the elongation of the activity space, iii) the centering of the activity space on the residential neighborhood, iv) the volume of activity, and v) the type of activity performed. The individual-level socio-economic status and degree of urbanicity of the place of residence in the Ile-de-France region are strong determinants of individuals’ spatial behavior. Results from the second study provide evidence that exposure to environmental characteristics supportive to walking highly differs between the residential neighborhood, the perceived residential neighborhood and the activity space. The measurement error resulting from the sole use of residential measures of exposure varies among SES groups and among categories of the degree of urbanicity of the residence. In the third empirical study a high density of destinations, the presence of a lake or waterway, and a high neighborhood education are associated with recreational walking. Finally, this study provides evidence of a strong influence of the environmental condition around the home and the recreational activity locations on the practice of recreational walking. Conclusion: This dissertation strengthen the conceptual grounds and empirical evidence that accounting for both residential and non-residential geographical environments individual get exposed is required to i) better proxy the true environmental exposure, ii) estimate environmental influences on health behaviors. In order to investigate the mechanisms through which environmental exposure influence physical activity, it is relevant to examine where people go, and what people actually do in terms of type of activity and constraints related to the activity performed. Identifying which activity places is most influential on physical activity informs on the geographical contexts health promotion interventions should target.

Abstract:

Dissertation submitted in partial fulfilment of the requirements for the Degree of Master of Science in Geospatial Technologies
Cycling has been considered a viable option to generate a modal shift from fossil dependent transportation modes. In this framework, measurements and tools that aid connected bicycle infrastructure planning have been developed. This is the case of the Bicycle Network Analysis score, a connectivity measure adapted for the U.S. It is based on the Levels of Traffic Stress methodology and computed mainly with OpenStreetMap data. Its aim is to quantify how well the low-stress bicycle network in a city connects people with the places they want to go. For this research, the BNA open source tool is adapted to a European context to validate its ability of quantifying low-stress connectivity. Three core elements are evaluated: stress network, destinations, and the overall score itself. They are related to cycling behaviors from two validation data sources: travel to work data in England and Wales, and crowdsourced bicycle trip routes in The Netherlands. The results indicate that in England and Wales, there is a significantly higher percentage of bicycle trips performed between origin-destination pairs with a low-stress connection between them. Additionally, a positive correlation is found between the percentage of bicycle trips within a city and its overall BNA score. In the Dutch case, the destinations core element is evaluated, determining that the destinations contemplated in the BNA score calculation are also among the highly frequented by cyclists. However, their importance within the score computation might require adjustments. Although a comprehensive validation cannot be achieved due to data limitations, evidence that providing low-stress connections between origins and destinations relates to bicycle commuting in cities is found. Therefore, special attention should be given to those measures that can greatly benefit the decision-making process when planning for sustainable cities.

Master's thesis of Urban Engineering
The challenges resulting from urbanization growth lead to a continuous need for innovation, regarding a wide approach of sustainable development, when both planning and managing the cities. Once the transportation sector is one with the largest impacts concerning pollutants and greenhouse gases emissions, it is peremptory that governments consider this sector as a target to work in order to achieve the global decarbonization goals set by 2030 Agenda. Therefore, the importance to act in the cities, concerning climate changes, implies a creative capability of interdisciplinary technicians to develop feasible methods to guide governments and citizens towards sustainable solutions of urban planning applied in short periods for long-term changes. The Municipal Council of Braga, a city in the north of Portugal, launched in 2018 the project BUILD – Braga Urban Innovation Laboratory Demonstrator, which is a Living Lab that intended to promote the city decarbonization. To achieve a behavioral change allowing a transition towards sustainable mobility, through a collaborative and co-created model between interdisciplinary technical team and stakeholders, a diverse range of activities with a people-centered approach was developed. For instance workshops, in which playful participatory processes and participatory mapping were applied. The format of the workshops was defined according to the stakeholder, namely the scholar community, the residents and general city-users of BUILD area. The workshops aimed at the development of an intervention in the public space, while simultaneously spreading and promoting the concepts of sustainable urban mobility and tactical urbanism among the citizens. Since it is a concrete and achievable solution applied in short periods, tactical urbanism represented an efficient method to develop actions of public participation regarding the city planning. At the same time it highlighted the importance of a cohesive and continuous action of population’s engagement. Furthermore, the promotion of sustainable mobility in a participatory model enables the construction and production of more live and inspiring cities, contributing, simultaneously, to tackle the causes of climate change and to improve urban life quality.
Os desafios resultantes do crescimento da urbanização impulsionam uma contínua necessidade de inovação, tanto no planeamento quanto na gestão das cidades rumo ao desenvolvimento sustentável. Uma vez que o setor de transportes é um dos com maiores impactos nas emissões de poluentes e gases de efeito estufa, é perentório que os governos considerem este setor como um alvo a ser trabalhado de forma a atingir as metas globais de descarbonização estabelecidas pela Agenda 2030. Portanto, para atuar nas cidades, no que diz respeito às mudanças climáticas, é necessário desenvolver métodos viáveis que orientem governos e cidadãos em busca de soluções sustentáveis de planeamento urbano. A Câmara Municipal de Braga, cidade do norte de Portugal, lançou em 2018 o projeto BUILD - Braga Urban Innovation Laboratory Demonstrator, que é um Living Lab que pretende promover a descarbonização da cidade. Para alcançar uma mudança comportamental que permita uma transição para a mobilidade sustentável, foram desenvolvidas diversas atividades com uma abordagem centrada nas pessoas. Por exemplo, oficinas, nas quais foram aplicados processos participativos lúdicos e mapeamento participativo. O formato das oficinas foi definido de acordo com o público-alvo, nomeadamente a comunidade escolar, os residentes e cidadãos em geral que utilizam a área BUILD. As oficinas visaram o desenvolvimento de uma intervenção no espaço público, ao mesmo tempo em que disseminaram e promoveram os conceitos de mobilidade urbana sustentável e urbanismo tático entre os cidadãos. Por se tratar de uma solução concreta e realizável, aplicada a curto prazo, o urbanismo tático representou um método eficiente para desenvolver ações de participação pública em relação ao planeamento da cidade. Ao mesmo tempo, destacou a importância de uma ação coesa e contínua de engajamento da população. Além disso, a promoção da mobilidade sustentável em um modelo participativo possibilita a construção e a produção de cidades mais vivas e inspiradoras, contribuindo, simultaneamente, para combater as causas das mudanças climáticas e melhorar a qualidade de vida urbana.

Trabalho Final do Mestrado Integrado em Medicina apresentado à Faculdade de Medicina
A Esclerose Múltipla é uma doença neurológica crónica que afeta cerca de 2.5 milhões de pessoas no mundo e causa dor, dificuldades de mobilidade e perdas cognitivas que podem ter impacto no bem-estar dos doentes. Este estudo tem como objetivo avaliar e clarificar o impacto da esclerose múltipla em situações de vida diárias, fadiga e independência.Métodos: A amostra incluiu 42 sujeitos, 24 mulheres e 18 homens e com uma idade mínima de 22 anos, idade máxima de 64 anos e uma média de idades de 45 anos. Os critérios de inclusão foram ter Esclerose Múltipla diagnosticada há mais de 2 anos, ser capaz de ler e escrever na língua portuguesa e a ausência de patologias traumáticas, ortopédicas, reumáticas ou vasculares ou outras que afetam a mobilidade, bem como comorbilidades funcionais ou estruturais do foro neurológico.Para medir o nível de participação foi usada o Perfil de Atividades e Participação relacionado com a mobilidade, para medir o estadio de doença foi usada a Expanded Disability Status Scale (EDSS). Esta duas escalas foram as mais usadas no estudo, onde se usaram também a Medida de Independência Funcional e a Escala de Impacto de Fadiga Modificada. Dada a distribuição de diferentes variáveis foram usados quer testes paramétricos quer testes não-paramétricos.Resultados: Não houve evidência estatística para o efeito da idade ou do género na EDSS, APPM ou Fadiga; Houve uma correlação positiva significativa e predição da EDSS na APPM; Houve uma correlação negativa significativa entre a EDSS e o score da Medida de Independência Funcional.Conclusões: Os resultados mostraram que a EDSS prediz os níveis de participação e que quanto mais avançada está a doença menor é a independência dos doentes. Este estudo concluiu também que o estadio de doença da Esclerose Múltipla é mais relevante do que os anos de doença no que diz respeito à predição dos níveis de participação. O estudo mostrou também que não há efeito do género no avançar da doença ou nos níveis de participação.
Multiple sclerosis (MS) is a neurological chronic disease that affects around 2.5 million people world-wide and causes pain, mobility difficulties and cognitive losses that may have impact on patient’s well-being. This study’s objective is to evaluate and clarify the impact of multiple sclerosis on daily life situations, fatigue and independence.Methods: The sample included 42 patients, 24 women and 18 men and with a minimum of 22 years of age, a maximum of 64 years and a mean age of 45 years. Inclusion criteria was having MS diagnosis for more than 2 years, being able to read and write Portuguese and the absence of traumatic, orthopedic, rheumatic, vascular pathologies or others which affects mobility or other functional or structural neurological comorbidities.To measure the level of participation it was used the Activities and Participation Profile related to Mobility (APPM) questionnaire, to measure the disease stage it was used the Expanded Disability Status Scale (EDSS). These were the two scales mainly used in this study. The Functional Independence Measure was used to assess the degree of independence and the Modified Fatigue Impact Scale was used to evaluate fatigue impact. Regarding the distribution of the different variables, either parametric or non-parametric tests were used.Results: There was no statistical evidence for age or gender’s effect on EDSS, APPM or fatigue; There was a significant positive correlation and prediction of EDSS on APPM; There was a significant negative correlation between EDSS and Functional Independence Measure score.Conclusions: The results shown that EDSS predicts participation levels and that the more advanced disease stage the less is patients’ independence is. This study also concluded that the stage of MS disease is more relevant than the years of disease with respect to the prediction of participation levels. This study also showed that there is no effect of gender on the advance of the disease stage or participation levels.

Films fabricated by spin-cast technique are used in organic polymer solar cell and polymer light emitting diode. The thickness of spin-cast film could be controlled below 300 nm. In the vertical carrier mobility measured by time of flight, we used drop-cast method to fabricate thick films (several micrometer) that light penetration depth is less than the total thickness of the film. However, the morphologies of the films by spin-cast and by drop-cast are different. The different morphologies would affect the charge carrier mobility. In order to measure the real films used in polymer solar cell and polymer light emitting diode, the charge generation layer is deposited on Indium Tin Oxide (ITO) glass, and the films are fabricated by spin-cast on the charge generation layer. In this work, the different weight ratio of P3HT:PCBM is dissolved in chlorobenzene, and these films are fabricated by drop-cast and spin-cast. The vertical charge carrier mobility of these different film processes are measured by time of flight technique. The results show the vertical electron mobility which film is fabricated by spin-cast is about two orders of magnitude lager than the film fabricated by drop-cast. As the result,

IGZO is a newly developed transparent conducting oxide with higher carrier mobility than traditional materials. In this study, the Hall mobility of distinct surface capping a-IGZO thin films is discussed. The electrical properties of a-IGZO thin films with sheet capping and island capping of calcium were measured, respectively the a-IGZO thin films without surface coating were used as the control group. The resistivity and Hall measurements were undertaken using van der Pauw method. The resistivity (ρ), carrier concentration (n), and Hall mobility (μ) were then calculated from a-IGZO thin films with different types of surface coating. The carrier concentration increases in the thin film with surface coating of calcium. However, the Hall mobility is not improved as predicted.

Abstract:

Overuse of the Interstate and National Highway Systems has led many urban freeways to suffer from recurrent congestion and high crash rates. One method of ameliorating these problems is through the use of Active Traffic Management (ATM). Within ATM, the practice of speed harmonization is well suited to improving safety and reducing delay. In this study, speed harmonization is applied to a segment of Interstate Highway 35, just south of downtown Austin, Texas. First, the need for congestion and safety improvements will be established. Then, the framework of a speed harmonization system will be developed through a synthesis of speed harmonization best practice. Next, the speed harmonization framework will be evaluated for its impact on efficiency through the development of before and after micro-simulation models. Finally, the trajectory files generated from simulation will be analyzed using surrogate safety measures to assess the safety impact of the proposed speed harmonization system.

Abstract:

The availability of numerous mobile agent systems with its own strengths and weaknesses poses a problem when deciding on a particular mobile agent system. In this dissertation, factors based on mobility, communication and security of the mobile agent systems are presented and used as a means to address this problem. To facilitate in the process of selection, a grouping scheme of the agent system was proposed. Based on this grouping scheme, mobile agent systems with common properties are grouped together and analyzed against the above-mentioned factors. In addition, an application was developed using the Aglet Software Development Toolkit to demonstrate certain features of agent mobility, communication and security.

Abstract:

The shortage of nurses in any health care setting increases workloads and complicates workflow. In South Africa the shortage is exacerbated by multiple factors, one of which is the emigration of nurses to countries that offer better benefits and working conditions. The purpose of the study was to explore and determine the views of nurse managers regarding staff turnover and retention, and to recommend effective measures to improve the retention of nurses. The inquiry was conducted in a KwaZulu-Natal hospital, a natural setting for the participants. The study utilized a qualitative, explorative, descriptive design. The population of this study comprised of 36 nurse managers. Purposive and convenience sampling techniques were applied to select a sample of 18 nurse managers. Data were collected through focus groups. Data were transcribed and analysed thematically, emerging patterns were noted. The researchers examined these categories closely and compared them for similarities and differences. identifying the most frequent or significant codes in order to develop the prominent categories. These were summarised in a narrative form. Four themes emerged from the findings: the staff turnover challenge; current retention strategies; measures to improve retention and strengthening management. The shortage of nursing staff was critical at this selected hospital, and this situation could be considered to be a microcosm of what is happening in public health care sectors in South Africa. Various measures were put in place to curb the high turnover. However, these measures had a fair to low level of success. Therefore, improved retention strategies are required to reduce the staff turnover. It is evident from the findings that needs to be done to investigate, plan and implement effective measures that are likely to retain nursing staff and recruit more nurses into the profession.
