Anonymous Call Detail Records (CDR’s) from mobile phone towers provide a unique opportunity to aggregate individual location data to overall human mobility patterns. Flowminder uses this data to improve the welfare of low- and middle-income countries. The movement patterns are studied through key measurements of mobility. This thesis seeks to evaluate the estimates of key measurements obtained with mobile phone towers through simulation of continuous human movement on a linear network. Simulation is made with an agent based approach. Spatial point processes are used to distribute continuous start points of the agents on the linear network. The start point is then equipped with a mark, a path with an end point dependent on the start point. A path from the start point to the end point of an agent is modeled with a Markov Decision Process. The simulated human movement can then be captured with different types of mobile phone tower distributions realized from spatial point processes. The thesis will initially consider homogeneous Poisson and Simple Sequential Inhibition (SSI) processes on a plane and then introduce local clusters (heterogeneity) with Matérn Cluster and SSI processes. The goal of the thesis is to investigate the effects of change in mobile phone tower distribution and call frequency on the estimates of key measurements of mobility. The effects of call frequency are unclear and invite more detailed study. The results suggest that a decrease in the total number of towers generally worsens the estimates and that introducing local clusters also has a negative effect on the estimates. The presented methodology provides a flexible and new way to model continuous human movement along a linear network.

Introduktion – Millennials, är den första generation som har växt med teknologi nära tillhands. För dem har mobilen fått bli en integrerad del av deras liv, vilket har påverkat hur dem som konsumenter interagerar med en butik och dess miljö. På många sätt har mobilen blivit en distraktion för dem när de är i butiken, men på vissa sätt så kan den också vara en hjälp för dem, speciellt i komplexa köp. Detaljhandlare har däremot fram tills nu sett mobilen som ett problem då den leder till att konsumenten ignorerar det som finns i butiken, men eftersom mobilen har betydande roll i konsumenternas liv bör de istället byta fokus. De måste istället hitta sätt att dra nytta av mobilanvändningen, både för deras egen fördel och förkonsumenternas. Syfte och metod – Studiens syfte var därmed att få en djupare förståelse för hur detaljhandlare kan hitta värde i mobilanvändandet för millennials i komplexa köp. Vidare, syftade den till att kunna ge teoretiska bidrag kring konsumentens värdeskapande, genom att sammanfläta mobilanvändandet med butiksmiljön. Studien gjordes som en kvalitativ fallstudie på IKEA genom användningen av två metoder. 47 respondenter tillfrågades att göra tre uppgifter på köksavdelning medans de bar eye trackingglasögon som filmade vad de gjorde. Efter det, fick de göra en komplimenterande semistrukturerad intervju, och alla data analyserades sedan med hjälp av en tematisk analys. Resultat och slutsatser – Resultatet visar att millennials använder sin mobil för att hjälpa dem navigera sig i butiken, hitta information, och viktigast, för att ta foton på information och inspiration. Däremot, även ifall konsumenten ser mobilen som ett värdefullt verktyg, visar också resultatet att trots det fortfarande är viktigt med personlig service i komplexa köp. Till sist, finns det också indikationer på att serviceerbjudande i butiken måste anpassas för att återge mer tydlig och relevant information, samt att skyltarna behöver skapa interaktioner mellan konsumenterna och mobilen, till exempel genom användningen av QR-koder. Teoretiskt, bidrar denna studie både genom att ge ytterligare stöd till tidigare studier och genom att bidra med nya insikter kring värdeskapande i serviceerbjudandet. / Introduction – The digital native generation, millennials, is the first generation to grow up with technology close at hand. For them the mobile phone is an integrated part of their lives, which has an impact on how they as consumers interact with the retail environment. In many ways the mobile phone can be a distraction for them in store, but in some ways, it can also be a help for them, especially in high involvement purchases. Retailers has up until now found the mobile phone to be a problem since it can make the consumers ignore the retail landscape. However, since the prominent role the mobile phone has in the consumers life, there need to be a switch in focus, and retailers needs to utilise it, both for their own and the consumers benefit. Purpose and methodology - The aim of this study was therefore to get a deeper understanding of how retailers can find value in mobile phone use for the millennial consumer in high involvement purchases. In addition, it aimed to make theoretical contributions to consumer value creation, by incorporating the mobile phone usage into the retail environment. The study was done using a qualitative multiple research method in a single case study on IKEA. 47 millennials respondents were asked to perform three tasks in the kitchen department while wearing eye tracking glasses to record their actions. Thereafter, a complementary semistructured interview was performed, and the data was later analysed using thematic analysis. Result and conclusion – The results show that the millennial consumers use their mobile phone to help them navigate the store, find information, but most importantly to take photos for information and inspirational purposes. However, even though many consumers found the mobile phone as a valuable tool, in high involvement purchases personalised service is still highly valued. Finally, the result indicated the services cape needs to be adapted with clearer and more relevant information as well as signs to create interactions with the consumer and the mobile phones such as QR codes. Theoretically, this study both supports the results from previous studies as well as contributes with new insights to the theoretical field of value in service.

Mobile phone usage involves the mobile phone, the telecommunications system, mobile phone users, and the adoption and use of the system. Mobile communications is a complex and rapidly changing industry consisting of the hardware, software, network and business aspects. Mobile phone users are influenced by demographic, social, cultural and contextual factors that complicate the understanding of mobile phone usage. Advances in technology and market competition drive the addition of new services and features. In contrast, human cognition and attention are more constrained and many users find it difficult to cope with the cognitive demands of mobile phone technology. The aim of this study is to develop a model for representing the influence of motivational needs and cultural factors on mobile phone usage variety. The link between motivational needs and mobile phone usage variety, the cultural factors that influence mobile phone usage variety, as well as usage spaces as an approach to representing usage variety, are researched. The research encompasses a literature study, structured interviews, a pilot study and a survey. The pilot study and survey yielded data about mobile phone usage of university students under the age of 30 in South Africa. The results from the statistical analysis were triangulated with the findings of the literature study and the observations made about mobile phone usage during this two-year period. A final survey was conducted to verify the model. The contribution of this study is a mobile phone technology usage model (MOPTUM) for representing the motivational and cultural factors that influence mobile phone usage variety in such a way that users can use the model to express their mobile phone usage needs in non-technical terms while marketers and designers can use the model to convert the expressed user needs into the features required. MOPTUM draws on concepts and models from sociology, computer-supported cooperative work, human-computer interaction and technology adoption models from the field of marketing. MOPTUM verifies some existing findings on mobile phone usage and then integrates and extends these existing models to provide a new model for understanding the motivational and cultural factors that influence mobile phone usage variety. / Computing / Ph.

D'après le rapport de l'OMS en 2015, près de la moitié de la population mondiale est exposée au risque du paludisme et le plus grand nombre des cas recensés se trouve en Afrique subsaharienne. Madagascar fait partie des pays où le paludisme est encore endémique. La géographie et le climat de l'île se traduisent par une répartition assez particulière du paludisme. Les plus fortes incidences sont observées sur les littoraux alors que les plus faibles le sont sur les Hautes Terres Centrales. Cinq zones épidémiologiques et opérationnelles ont été définies par les services de lutte contre le paludisme : Est, Ouest, Sud, Hautes Terres et les Marges. Cette étude vise à apporter une meilleure compréhension de l'épidémiologie du paludisme et de mesurer l'impact des mobilités humaines sur la transmission des zones à forte transmission vers les zones à faible transmission afin de contribuer à mieux cibler les actions de contrôle par les acteurs de la santé publique. Elle offre une nouvelle approche permettant d'évaluer la dynamique spatio-temporelle du paludisme, de quantifier la circulation de l'infection palustre en tenant compte de la mobilité de la population par l’utilisation des données de téléphonie mobile et d'identifier les principales zones exportatrices et importatrices de la maladie. En premier lieu, à travers une analyse rétrospective des données d'incidence, ce travail a montré une hétérogénéité évidente dans chaque stratification épidémiologique et la recrudescence de la maladie sur les Hautes Terres et les Marges. En second lieu, indépendamment de la densité de la population, nous avons montré que les Hautes Terres et surtout la capitale Antananarivo sont une zone à fort risque d'importation de paludisme et que les zones exportatrices sont surtout situées à l'Est et à l'Ouest. Enfin, notre enquête de terrain a souligné l'importance d'une mobilité inter district faible et d'une mobilité intra district voire intra communale importante qui mériterait d'être prise en compte dans la mesure de la circulation de l'infection palustre. Cette étude a permis de mettre en lumière que le paludisme est très dynamique à Madagascar avec un degré d'intensité différent même si les zones appartiennent à la même stratification. Ce constat devrait se traduire par une adaptation des stratégies de lutte. Enfin, la mobilité humaine joue un rôle important dans la transmission. A l'heure où la téléphonie mobile s'est largement diffusée à Madagascar, son utilisation pour estimer le déplacement des populations devient un outil pertinent pour contribuer à orienter le contrôle des maladies. / According to the 2015 WHO report, almost half of the world population is exposed to malaria, with the largest number of reported cases in sub-Saharan Africa. Madagascar is one of the countries where malaria is still endemic because of its geographical location. As a matter of fact, the geography and climate of the island gives a specific epidemiological stratification of malaria. There are five malaria epidemiological zones: East, West, South, Highlands and Fringe. The highest incidence is observed on coastal areas, while the lowest incidence is observed on the Central Highlands. This study aims to provide a better understanding of the epidemiology of malaria and to measure the impact of human mobility on transmission from high transmission areas to low transmission areas in order to help better target control actions by public health actors. This study proposes an alternative approach to assess the spatiotemporal dynamics of malaria, quantify the circulation of malaria infection and take into account the mobility of the population to identify the main source and sink areas of malaria. Firstly, through a retrospective analysis of incidence data, this work showed a clear heterogeneity in each stratum, and an increase the Highlands and the Fringe areas. Secondly, regardless of the population density, we have shown that the Highlands and especially the capital of Madagascar, Antananarivo, was a zone at high risk of the importation of malaria. The source areas were mainly in the eastern and the western part of the country. Finally, our field survey highlighted the importance of low inter-district mobility and high intra-district or even intra-communal mobility which should be taken into consideration when assessing the spreading of malaria infection. This study revealed that malaria is very dynamic in Madagascar with a different degree of intensity even if such areas belong to the same stratum. This observation should translate into an adaptation of control strategies. Finally, human mobility plays a leading part in the transmission. At a time when mobile telephony has spread widely in Madagascar, its use to estimate the mobility of populations is becoming a relevant tool to help guide disease control.

This dissertation considers the impact mobile media technologies have on the production and consumption of memory narratives and cultural memory discourses in Canada. Although this analysis pays specific attention to concepts of memory, heritage, and public history in its exploration of site-specific digital narratives, it is set within a larger theoretical framework that considers the relationship between mobile technology and place, and how the mobile phone in particular can foster both a sense of place and placelessness. This larger framework also includes issues of co-presence, networked identity, play, affect, and the phenomenological relationship between the individual and the mobile device. This is then considered alongside memory narratives (both on the national and quotidian levels) at specifically sanctioned sites of national commemoration (monuments, historic sites) and also in everyday urban spaces. To this end, this dissertation covers a wide range of augmented reality apps and forms of digital storytelling including locative media narratives, site-specific digital performances, social media and crowdsourced heritage archives, and urban mobile gaming and playful mapping. Despite common criticism that mobile phones only serve to distract us from our surrounding environment, I argue that mobile technology can generate deeper, more affective attachments to places by reformulating ways of perceiving and moving through them. They do this by insisting that place is more than just its material properties, but rather is composed of a fluctuating relationship between materiality, time, and affect. Following this framework, I also emphasize how mobile technology shifts the traditional mission of the archive to preserve and protect the past to something more playful, more affective, and more preoccupied with the circulation of the past in the present. Included in this analysis are crowdsourced archives created on social media platforms which, I argue, are particularly well suited to capturing the dynamic qualities of memory and living heritage practices. A contributing factor in this is the mobile phone’s position as a site of intimacy and co-presence, which situates it in a long history of communication technologies that employ rhetorical and technological strategies of co-presence, immediacy, and intimacy. Chapter one examines the role that locative media narratives play at official sites of memory in Canada’s capital region from app-based historical tours to more playful narrative encounters, through the lens of the archive and the repertoire. Chapter two then considers the digital site-specific performance piece, LANDLINE, to unpack how mobile media foster everyday place memories in urban spaces through the mobile phone’s position as a site of intimacy for geographically distant, but virtually co-present, individuals. Chapter three analyzes my own experimental method, Maplibs, which follows a mobile game structure to encourage participants to engage in acts of playful placemaking and collaborative storytelling in order to highlight an alternative process of engaging with place that carries the past forward in meaningful ways. And finally, chapter four analyzes the social media group “Lost Ottawa” to explore how collaborative memory communities mobilize through social media platforms like Facebook and create new forms of participatory heritage. In all of this, place is understood as a dynamic assemblage of stories and memories that the mobile phone, through its ubiquitous impact on social practices, plays a key role in shaping.
