This essay explores the early experiences of Bangladeshi blue-collar service workers in digitalising their livelihoods. It is a qualitative study that surveys and interviews service-providers in Dhaka who use the business aggregator platform Sheba.xyz, an online service marketplace, and seeks to understand what brought these self-employed micro-entrepreneurs, previously outside the digital economy, to adopt an ICT-enabled solution. The study is guided by Diffusion of Innovations (DOI) theory, one of the historically dominant paradigms in the field of communication for development (C4D). The overarching research question is, “Why did blue-collar service-providers in Dhaka adopt and use a digital business aggregator platform?” The aim is to explore what motivated/discouraged and enabled/hindered innovation adoption among a group of users previously marginalised from digital and financial inclusion. The findings suggest that adoption of Sheba.xyz among service-providers was not driven so much by a desire to digitalise one’s business per se, and as a means of mitigating a previous inability to do so. Rather, the factors that emerge from the qualitative data are other perceived relative advantages of the solution – of increase in customers, income, and opportunity. Survey respondents and interviewees also displayed strong affiliation with, and trust in, the platform provider; an alertness for fair treatment; and a drive to prosper, suggesting that they embraced a comprehensive concept and altered life situation where belonging, respect, and self-fulfilment matters, rather than narrowly adopted a new mobile application.

Le développement durable et la transition énergétique sont aujourd’hui des préoccupations majeures de la scène européenne. Parmi les influents demeure le domaine du bâtiment qui représente le premier levier d’action pour réduire notre empreinte carbone. Pour autant, les moyens actuels mis en œuvre ne prennent pas assez en compte l’occupant et son comportement vis-à-vis de la performance énergétique. Cette recherche problématise, par une approche info-communicationnelle, les interactions acteur-habitat dans le but d’améliorer les stratégies d’intervention. Elle montre qu’une approche compréhensive, suivant un paradigme sémantico-actionnel, permet d’analyser la manière dont les usagers appréhendent et s’approprient un espace dans lequel ils se sentent en situation de confort, permettant ainsi de guider la recherche d’informations utiles pour les acteurs intervenant sur le cadre de vie des usagers en vue de mieux les satisfaire. Dans un souci d’économie de la fonctionnalité concernant le confort thermique, cette démonstration passe par la mise en œuvre et l’expérimentation d’une démarche interdisciplinaire qui doit être capable d’une part d’appréhender ce processus de construction de sens de l’environnement bâti par les usagers et, d’autre part, capable de rendre opérationnels les indicateurs résultant des critères comportementaux, afin de les intégrer aux calculs techniques. Cette démarche, fondée à partir de la méthode d’écoute des besoins et de hiérarchisation des attentes développée par le laboratoire DeVisu à l’Université de Valenciennes, interprète la perception du confort d’un profil majoritaire d’usagers et les intègre dans un processus construit sous l’angle technique. / The sustainable development and the energetic transition as well are main concerns in Europe. The construction sector is a fundamental driver of the reduction of the carbon footprint. Furthermore, most of the current practices does not take enough into account neither the occupants’ needs nor their behavior regarding the energetic performance. Grounded on the information-communication framework, this research focuses on the definition of the interactions between the actor and its habitat to lead the strategies of rehabilitation. In line with the semantico-actional paradigm, we provide evidence that a comprehensive approach enables the analysis of the process by which the users apprehend and appropriate a living space perceived as comfortable. Practically, it ensues from this analysis a better definition of the users’ needs and a guideline for the construction stakeholders to collect information about users’ expectations so as to satisfy them. In a sake of functionality economics concerning the thermal comfort, the purpose of this interdisciplinary investigation is twofold: First, the understanding of the users’ sense-making about the environment of the habitat. Second, the definition and the implementation of operating behavioral metrics in the technical optimization of the habitat. Referring to the method of listening to the needs and hierarchy of needs, developed by the DEVISU research center of the University of Valenciennes (France), we interpret the perceived comfort according to the main users’ profile in order to integrate it in the technical processes of rehabilitation.

Online users struggle with different concerns whenever they use information systems. According to Miyazaki and Fernandez (2001), there are three important categories of concerns for online users: privacy concern, third party fraudulent behavior concern ("system security"), and online website fraudulent behavior concern ("security"). Kim, Sivasailam, and Rao (2004) proposed a similar categorization for web assurance dimensions. They argue that online websites are supposed to address users' privacy, security, and business integrity concerns to decrease user concerns. Although several researchers tried to answer how different factors affect these concerns and how these concerns affect users' behavior, there are so many ambiguities and contradictions in this area. This Essay I in this work develops a comprehensive map of the role of online privacy concern to identify related factors and categorize them through an in-depth literature review and conducting meta-analysis on online privacy concern. Although users have concerns about their privacy and security, there is still growth in the number of internet users and electronic commerce market share. One possible reason is that websites are applying assurance mechanisms to ensure the privacy of their users. Therefore, it could be an interesting research topic to investigate how privacy assurance mechanisms affect users concern and, consequently, their behavior in different concerns such as e-commerce and social networking sites. Different types of web assurance mechanisms are used by websites. The most prevalent among these assurance mechanisms include web assurance seals and assurance statements and privacy customization features. Essay II and III aims to address how these mechanisms influence e-commerce and social networking sites users' behavior. Essay II applies the procedural fairness theory by Lind and Tyler (1988) to explain how and why the web assurance mechanisms affect consumers' perceived risks. Essay III addresses the issue of self-disclosure on social networking sites. Applying protection motivation theory, this study aims to evaluate the effect of web assurance mechanisms on online privacy concern and self-disclosure behavior on the social networking sites.

This thesis deals with the analysis and design changes to a specific company information system under real conditions, and is therefore more practically oriented. The information system is studied both from the perspective of the end user, which is the focus, and in terms of operation and implementation of program solutions. The information system is studied as a whole in a broader context, not only in terms of applications (software), but also in terms of the flow of information, storage and organization of data, users, security, hardware, etc. It should serve to the company as a guide for the elimination of inefficient and / or risk areas, thereby helping to improve work productivity and employee satisfaction.

The goal of this master's thesis is a creation of dataset capturing selected users' activities, network analysis of this dataset, design and implementation of method to detect selected users' activities and discussion of achieved results. 4 devices have been chosen for the creation of this dataset.

Titel: Kan funktioner från kryptovalutor förbättra Riksbankens föreslagna E-krona? Författare: Oscar Guregård och Viktor Nilsson Handledare: Mikael Knutsson Bakgrund: I takt med digitaliseringen minskar det fysiska kontantanvändandet. Riksbanken bemöter denna förändring med att utforska möjligheterna att ge ut en digitala kontanter, E-kronan. Eftersom detta är ett nytt område för Riksbanken och projektet fortfarande är i en utvecklingsfas finns det problemområden med de funktioner som Ekronan planeras ha. Forskning inom utveckling av digitala centralbankspengar antyder att kryptovalutor, ett alternativ till centraliserade betalningsstrukturer, har olika funktioner som kan lämpa sig väl för digitala utföranden av valutor. Studien ämnar att analysera olika funktioner inom kryptovalutorna Bitcoin, Ethereum och Ripple för att avgöra om de kan förbättra den föreslagna E-kronan. Syfte: Studiens syfte är att utifrån Riksbankens mål identifiera svagheter och problemområden i det nuvarande förslaget på teknisk lösning för E-kronan för att sedan analysera om funktioner från kryptovalutor kan åtgärda dessa. Om en funktion från en kryptovaluta kan åtgärda ett problem med E-kronan ska det undersökas på vilket sätt funktionen uppfyller Riksbankens mål till en högre grad än den nuvarande lösningen på problemet. Metod: En kvalitativ metod har använts för att samla tidigare forskning om fenomenet digitala centralbankspengar samt Riksbankens egna rapporter om E-kronans utförande för att genom intervjuer med kritiker finna problemområden. Dessa problemområden har med hjälp av funktioner från Bitcoin, Ethereum och Ripple analyserats för att avgöra om kryptovalutornas funktioner är bättre lämpade för att uppfylla E-kronans mål än Riksbankens egna förslag. Resultat: Studien finner att E-kronans största problemområden grundar sig i en överdriven komplexitet. Kryptovalutorna som undersökts och deras funktioner kommer med stor sannolikhet bidra till ännu mer komplexa utföranden istället för att skapa enklare lösningar, något som E-kronans kritiker värdesätter. / Title: Can functions from cryptocurrencies improve the Riksbank’s proposed E-krona? Authors: Oscar Guregård and Viktor Nilsson Supervisor: Mikael Knutsson Background: As digitalisation develops, the use of physical banknotes and cash decreases. The Riksbank is responding to this by exploring the possibility of issuing digital cash, the E-krona. As this is uncharted territory for the Riksbank and the project is still in development, there are challenges with the proposed functions that the E-krona is expected exhibit. Research in the development of Central Bank Digital Currencies, CBDC, suggests that cryptocurrencies, an alternative to centralized payment structures, have a variety of functions that may be well suited for CBDC’s. The study aims to analyze various features and functions of the cryptocurrencies Bitcoin, Ethereum and Ripple in order to determine whether they can improve the proposed E-krona or not. Purpose/object: The aim of the study is to identify weaknesses and problem areas in the current proposal for a technical solution for the E-krona based on the goals and objectives presented by the Riksbank, and to then analyze whether functions from cryptocurrencies can remedy these. If a function from a cryptocurrency can solve a problem with the E-krona, the study must examine in what way the function meets the Riksbank’s objectives to a greater degree than the current proposed solution. Methodology: A qualitative methodology has been used to gather previously researched data on the phenomenon CBDC and the Riksbank’s own reports on the aspects of the E-krona in order to find problem areas through interviews with critics of the project. These problem areas have been analyzed along with functions from Bitcoin, Ethereum and Ripple to determine whether the cryptocurrencies’ functions are better suited to meet the E-krona’s goals than the Riksbank’s own proposals. Results: The study finds that the E-krona’s biggest problem areas are based on excessive complexity. The cryptocurrencies that have been examined and their functions will probably contribute to even greater complexity in the functions of the E-krona instead of creating simpler solutions, something that the critics value.

Chaque année, des millions de personnes meurent et beaucoup d'autres subissent des séquelles graves à la suite d'accidents de la route. Malgré une multitude d’initiatives, le nombre de cas mortels et d'accidents graves augmente chaque année en engendrant des problèmes préoccupants à la fois sociaux, économiques et sanitaires. En raison de leur nombre élevé et de l'absence de protection personnelle, plus de la moitié de ces décès concerne les usagers vulnérables (en anglais, vulnerable road users - VRU) regroupant les piétons, cyclistes et motocyclistes. Les appareils mobiles, combinés à la technologie de Fog Computing (ou informatique géodistribuée, ou même informatique en brouillard), représentent une solution réaliste à court terme pour les protéger en les avertissant de l’imminence d'un accident de circulation. L’omniprésence des appareils mobiles et leurs capacités de calcul élevées font de ces appareils un élément important à considérer dans les solutions de sécurité routière. Le Fog Computing offre des fonctionnalités adaptées aux applications de sécurité routière, puisqu’il s’agit d’une extension du Cloud Computing permettant de rapprocher les services informatiques, le stockage et le réseau au plus près des utilisateurs finaux. Par conséquent, dans cette thèse, nous proposons une architecture réseau sans infrastructure supplémentaire (PV-Alert) pour des fins de sécurité routière et reposant uniquement sur les appareils mobiles des VRU et des conducteurs sur la route avec l’aide du concept de Fog Computing. Les données géographiques et cinématiques de ces appareils sont collectées et envoyées périodiquement au serveur fog situé à proximité. Le serveur fog traite ces données en exécutant un algorithme de calcul de risque d’accident de circulation et renvoie des notifications en cas d'accident imminent. L’évaluation de cette architecture montre qu’elle est capable de générer des alertes en temps réel et qu’elle est plus performante que d’autres architectures en termes de fiabilité, d’évolutivité et de latence. / Annually, millions of people die and many more sustain non-fatal injuries because of road traffic crashes. Despite multitude of countermeasures, the number of causalities and disabilities owing to traffic accidents are increasing each year causing grinding social, economic, and health problems. Due to their high volume and lack of protective-shells, more than half of road traffic deaths are imputed to vulnerable road users (VRUs): pedestrians, cyclists and motorcyclists. Mobile devices combined with fog computing can provide feasible solutions to protect VRUs by predicting collusions and warning users of an imminent traffic accident. Mobile devices’ ubiquity and high computational capabilities make the devices an important components of traffic safety solutions. Fog computing has features that suits to traffic safety applications as it is an extension of cloud computing that brings down computing, storage, and network services to the proximity of end user. Therefore, in this thesis, we have proposed an infrastructure-less traffic safety architecture that depends on fog computing and mobile devices possessed by VRUs and drivers. The main duties of mobile devices are extracting their positions and other related data and sending cooperative awareness message to a nearby fog server using wireless connection. The fog server estimates collision using a collision prediction algorithm and sends an alert message, if an about-to-occur collision is predicted. Evaluation results shows that the proposed architecture is able to render alerts in real time. Moreover, analytical and performance evaluations depict that the architecture outperforms other related road safety architectures in terms of reliability, scalability and latency. However, before deploying the architecture, challenges pertaining to weaknesses of important ingredients of the architecture should be treated prudently. Position read by mobile devices are not accurate and do not meet maximum position sampling rates traffic safety applications demand. Moreover, continuous and high rate position sampling drains mobile devices battery quickly. From fog computing’s point of view, it confronts new privacy and security challenges in addition to those assumed from cloud computing. For aforementioned challenges, we have proposed new solutions: (i) In order to improve GPS accuracy, we have proposed an efficient and effective two-stage map matching algorithm. In the first stage, GPS readings obtained from smartphones are passed through Kalman filter to smooth outlier readings. In the second stage, the smoothed positions are mapped to road segments using online time warping algorithm. (ii) position sampling frequency requirement is fulfilled by an energy efficient location prediction system that fuses GPS and inertial sensors’ data. (iii) For energy efficiency, we proposed an energy efficient fuzzy logic-based adaptive beaconing rate management that ensures safety of VRUs. (iv) finally, privacy and security issues are addressed indirectly using trust management system. The two-way subjective logic-based trust management system enables fog clients to evaluate the trust level of fog servers before awarding the service and allows the servers to check out the trustworthiness of the service demanders. Engaging omnipresent mobile device and QoS-aware fog computing paradigm in active traffic safety applications has the potential to reduce overwhelming number of traffic accidents on VRUs.

In Peru, The National Health Authority (SUSALUD) is granted the responsibility to promote, protect and defend the health rights of every citizen. However, in the Peruvian Health System (PHS) there exists an insufficient culture of health rights, a low level of knowledge of health rights by the population, and a limited degree of cooperation between users, providers and funders. In light of this limited popular participation in the health rights of the citizenry, it has been necessary for SUSALUD to pursue various activities in order to promote the exercise of health rights by Peruvians. Among the strategies implemented are the development of Organized Boards of Users (OBU) and a Program of Integrated Actions for the Promotion of Health Rights (PIAPHI). The aim of both interventions is to increase the level of trust between citizens and government, which fosters and strengthens the capacity of citizens to pursue their health rights. In this article we begin with a brief presentation on the state of knowledge, attitudes and practices of users of the health system regarding their rights. Then we explain both programs, their goals and procedures, and a general description of their activities. Also, some indicators of process and some results are presented along with discussion and future prospects. We believe that the gradual implementation of the OBU and PIAPHI programs will enhance the participation of Peruvians in their health system, and will contribute positively to their empowerment and the pursuit of their health rights. / In Peru, The National Health Authority (SUSALUD) is granted the responsibility to promote, protect and defend the health rights of every citizen.
