<p>With the large number of Android apps available in app stores such as Google Play, it has become increasingly challenging to choose among the apps. The users generally select the apps based on the ratings and reviews of other users, or the recommendations from the app store. But it is very important to take the security into consideration while choosing an app with the increasing security and privacy concerns with mobile apps. This thesis proposes different ranking schemes for Android apps based on security apps evaluated from the static code analysis tools that are available. It proposes the ranking schemes based on the categories of evidences reported by the tools, based on the frequency of each category, and based on the severity of each evidence. The evidences are gathered, and rankings are generated based on the theory of Subjective Logic. In addition to these ranking schemes, the tools are themselves evaluated against the Ghera benchmark. Finally, this work proposes two additional schemes to combine the evidences from difference tools to provide a combined ranking.</p>

Cette thèse étudie la productivité du consommateur dans le cadre de son magasinage sous l’influence de la technologie mobile. Dans un premier temps, une revue de littérature pluridisciplinaire a mis en exergue la polysémie du concept de productivité et les particularités de la définition de la productivité dans le secteur tertiaire. Une analyse comparative des travaux sur la productivité du consommateur a par la suite permis de pointer la diversité des définitions et des méthodes de mesure de ce concept et de justifier la pertinence de revisiter ce concept au niveau d’une expérience de magasinage dans le contexte digitalisé en prenant en compte les caractéristiques des technologies mobiles. À cet effet, une étude qualitative à partir de 31 entretiens semi-directifs a été réalisée. L’analyse des verbatim assistée du logiciel NVivo a débouché sur une conceptualisation élargie de la productivité du consommateur, comprenant l’efficience temporelle, l’efficience monétaire, et l’efficacité. Les résultats des entretiens et de la revue de littérature ont servi à construire un modèle conceptuel de productivité du consommateur sous l’influence du smartphone, explicitant les antécédents des dimensions de la productivité du consommateur et leurs effets sur la satisfaction. Enfin, un échantillon de 300 individus a permis de tester ce modèle par équations structurelles dans le cadre de magasinage vestimentaire. Les données ont été analysées et modélisées par équations structurelles à l’aide du logiciel Smart PLS. Les résultats de l’étude quantitative attestent d’un effet positif significatif des dimensions de la productivité du consommateur sur la satisfaction. Les relations entre l’efficacité et l’efficience temporelle, d’une part, et la satisfaction, d’autre part, sont modérées par la fréquence d’utilisation du smartphone pour le magasinage vestimentaire. Les résultats ont également permis d’identifier les antécédents des dimensions de la productivité du consommateur : la polychronicité, la conscience temporelle, la conscience de prix, l’implication, l’attitude envers les technologies mobiles et le choix des canaux marketing dans le parcours d’achat. Au vu des résultats des deux études, nous discutons la pertinence pour les distributeurs d’adopter la démarche de management de productivité du consommateur appuyée sur les possibilités offertes par la technologie mobile. / This PhD dissertation explores consumer shopping productivity under the influence of mobile technology. First, a multidisciplinary review of productivity literature emphasized the polysemy of productivity concept and some specific features of its definition in service industry. A comparative analysis of consumer productivity literature highlights the diversity of approaches to the analysis of consumer productivity and of its measures, and the relevance to revisit this concept in the digital world, taking into account the specific features of mobile technology.To do so, we realized a qualitative study by 31 semi-structured interviews. The verbatim analysis by means of NVivo software resulted in an extended conceptualization of consumer productivity, including temporal efficiency, monetary efficiency, and efficacy. Based on the literature review and the qualitative study results, we proposed a conceptual model of consumer productivity under the influence of mobile technologies, presenting the antecedents of consumer productivity dimensions and their impact on consumer satisfaction.Finally, a sample of 300 individuals was used to test this model in the context of apparel shopping. The data were analyzed by the structural equations modelling partial least squares with Smart PLS software. The results of the quantitative study confirm the positive impact of consumer productivity on satisfaction. The relations between efficacy and temporal efficiency were moderated by the frequency of the use of smartphone in apparel shopping. The results allowed us to identify the antecedents of consumer productivity: polychronic orientation, time consciousness, price consciousness, implication, attitude towards mobile technologies, and the choice of marketing channels in shopping trips. In the light of the results of the two studies, we argue for the relevance of consumer productivity management approach for retailers exploiting the vast opportunities offered by mobile technologies.

No / In this chapter, augmented space is described as the layering of media technologies onto the physical space of the city. The approach assesses salient aspects of the experience of space in everyday life, the city and urban space more generally. The chapter discusses these in relation to the deployment of augmenting technologies and modes of display associated with augmented reality, new and digital media: visual or otherwise.

These case studies indicate the potential of augmented reality in areas of a) urban design, b) tourism and heritage, and c) the promotion of cycling for health and the creation of alternative transport infrastructure. The main characteristics of AR and augmented space are presented. This is followed by a discussion and development of hybrid research tools and applied in two case studies with a view to providing a potential roadmap for future work in this area.

<div>As wearable devices, like smartwatches and fitness monitors, gain popularity and are being touted for clinical purposes, evaluating the resilience and security of wearable operating systems (OSes) and their corresponding ecosystems becomes essential. One of the most dominant OSes for wearable devices is Wear OS, created by Google. Wear OS and Android (its counterpart OS for mobile devices) share similar features, but the unique characteristics and uses of wearable devices posses new challenges. For example, wearable applications are generally more dependent on device sensors, have complex communication patterns (both intra-device and inter-device), and are context-aware. Current research efforts on the Wear OS are more focused on the efficiency and performance of the OS itself, overlooking the resilience or security of the OS or its ecosystem.</div><div> </div><div>This dissertation introduces a systematic analysis to evaluate the Wear OS's resilience and security. The work is divided into two main parts. First, we focus our efforts on developing novel tools to evaluate the robustness of the wearable OS and uncover vulnerabilities and failures in the wearable ecosystem. We provide an assessment and propose techniques to improve the system's overall reliability. Second, we turn our attention to the security and privacy of smart devices. We assess the privacy and security of highly interconnected devices. We demonstrate the feasibility of privacy attacks under these scenarios and propose a defense mechanism to mitigate these attacks.</div><div> </div><div>For the resilience part, we evaluate the overall robustness of the Wear OS ecosystem using a fuzz testing-based tool [DSN2018]. We perform an extensive fault injection study by mutating inter-process communication messages and UI events on a set of popular wearable and mobile applications. The results of our study show similarities in the root cause of failures between Wear OS and Android; however, the distribution of exception differ in both OSes. Further, our study evidence that input validation has improved in the Android ecosystem with respect to prior studies. Then, we study the impact of the state of a wearable device on the overall reliability of the applications running in Wear OS [MobiSys2020]. We use distinguishable characteristics of wearable apps, such as sensor activation and mobile-wearable communication patterns, to derive a state model and use this model to target specific fuzz injection campaigns against a set of popular wearable apps. Our experiments revealed an abundance of improper exception handling on wearable applications and error propagation across mobile and wearable devices. Furthermore, our results unveiled a flawed design of the wearable OS, which caused the device to reboot due to excessive sensor use.</div><div><br></div><div>For the security and privacy part, we assess user awareness toward privacy risks under scenarios with multiple interconnected devices. Our results show that a significant majority of the users have no reservation while granting permission to their devices. Furthermore, users tend to be more conservative while granting permission on their wearables. Based on the results of our study, we demonstrate the practicability of leaking sensitive information inferred from the user by orchestrating an attack using multiple devices. Finally, we introduce a tool based on NLP (Natural Language Processing) techniques that can aid the user in detecting this type of attack.</div>

Recently, it has been admitted by many researchers that students today are "digital natives" who already utilize several different technologies everyday with different purposes. Furthermore, while there is a plethora of research about learners' perceptions in language pedagogy, there is a paucity of information and research that could move beyond generic perception studies especially regarding new technologies. Accordingly, educators are still concerned not only with how to encourage EFL learners to adopt emerging technologies that could be invaluable in their language learning processes, but also with how to keep students interested in what they are learning. Thus, an understanding beyond students' perceptions with a purposive focus on their approach to technology by also exploring factors that have an influence on their adoption of emerging technologies is the key to knowing how to motivate students to integrate new technologies, and how to keep students interested in the learning process. Therefore, the purpose of this study was three-fold: to identify language learners' approaches to technologies; to examine their attitude toward emerging technologies with a focus on their familiarity, actual use, intentions and perceptions; and finally to analyze the factors and relationships among these factors that best predict language learners' intentions and decisions to use emerging technologies. The study specifically aimed to explore the following emerging technologies: (a) social networking, (b) mobile learning, and (c) digital games as major emerging technologies of today with also a focus on other emerging technologies: (a) augmented reality, (b) wearable technologies, (c) virtual assistants, (d) massive online open courses, (e) 3D printing and (f) online language learning platforms. This mixed methods study benefitted from multiple disciplines, and presented several different perspectives to achieve its aim. The data were obtained through a survey, open-ended questions, and semi-structured interviews. The quantitative data were analyzed through descriptive and inferential statistics. In addition, structural equation modeling was utilized and path analysis was employed to draw on two complementary frameworks: innovation diffusion theory (Rogers, 2003), especially its application in technology adopter categories (TACI) (Dugas, 2005), and the decomposed theory of planned behavior (DTPB) (Taylor & Todd, 1995), which was adapted for this research. The qualitative data was analyzed through thematic content analysis, and used to triangulate and affirm what the quantitative data was showing. The findings indicated that technology adopter categories were normally distributed among EFL learners at a public and a private university in Turkey. Although most EFL learners were quite familiar and confident with major emerging technologies, they were not very familiar with minor emerging technologies. As for an awareness of the benefits of all listed emerging technologies, the study revealed that EFL learners' awareness is quite high; however, it was also found that participants' intention to use these emerging technologies and their actual use were very low. Finally, the results showed that the adapted DTPB was useful in explaining much of the variance in the intention to integrate technology into language learning processes by EFL learners, and attitude was the most important predictor and factor of behavioral intention. Given these findings, this research aims to contribute to the literature in innovation diffusion, user adoption and language pedagogy by offering several theoretical, methodological, and pedagogical implications and directions for future research and applications.

Mobile technologies are emerging as one way to help address health challenges in many countries, including in Least Developed Countries. Mobile technology can reach a large share of the population but in order to provide effective support to healthcare services, technology, information collection and dissemination, and work processes need to be well aligned. The thesis uses a design science methodological approach and mixes qualitative and quantitative data analysis to address the question of, How can mobile technologies be effectively integrated with routine healthcare services? The study concerns the design, implementation, and evaluation of a mobile technology-based system, called SMSaúde, with the aim of improving the care of patients with HIV/AIDS and tuberculosis in Mozambique. The work started with the elicitation of functional and user requirements, based on focus group discussions. An important challenge, as in many mHealth interventions, was the integration with routine healthcare services and the existing IT systems, as well as developing a scalable technical structure. The system has now been in routine use since 2013 in more than 16 healthcare clinics in Mozambique. Evaluation was done by a randomised controlled study. Analysis of patient records showed that retention in care in urban areas was significantly higher in the intervention group than in the control group. In a user study both patients and health professionals were very positive to the system. The thesis contributes to research by demonstrating how information system artefacts can be constructed and successfully implemented in resource-constrained settings. The practical contributions include the designed artefact itself as well as improved healthcare practices and mHealth policy recommendations.

Depuis quelques années, les progrès réalisés dans le domaine des technologies de l’information et de la communication (TIC) ont stimulé la mondialisation sociale et économique entraînant l’avènement d’une société dite de l’information. Les campagnes élaborées autour de la dite société prônent la nécessité voire l’urgence pour les pays africains d’utiliser ces technologies afin d’atteindre un niveau de développement élevé. La société malienne n’échappe pas à cette situation. Les télécommunications y jouent un rôle déterminant ainsi que les stratégies tournées vers l’accès universel.Cependant, les progrès technologiques participent à l’atomisation de la société en élargissant particulièrement le fossé catégoriel entre les hommes et les femmes. Cette situation constitue une préoccupation pour tous les acteurs d’autant plus que, selon les Nations Unies, le manque d’accès aux TIC constitue le troisième défi crucial pour la femme après la pauvreté et la violence. Aussi, la prise en compte du genre et l’intégration des femmes dans la réflexion sur les TIC et le développement prennent- elles encore plus d’importance malgré les contraintes et l’écart entre le « dire » et le « faire ». Ce travail s’intéresse aux enjeux que recèle l’usage d’une technologie comme le téléphone mobile pour la femme malienne dans un contexte où tradition et modernité se confrontent. Autrement dit, il est question d’analyser la manière dont le téléphone parvient à s’insérer dans le quotidien de la femme malienne opératrice économique, les pratiques nouvelles ainsi que les transformations qu’il occasionne. / In recent years, progress made in the field of information and communication technologies (ICT) has stimulated social and economic globalization, leading to the development of an information society. Widespread campaigns around that society advocated the need and even the urgency for African countries to use these technologies to reach the expected level of development of which the nation Mali is not an exception. In that area telecommunications and affiliated strategies oriented towards universal access play an important role. However, technological advances are involved in the atomization of society especially broadening the gap between men and women. Moreover, stakeholders are concerned by this situation, especially since, according to the United Nations, the lack of access to ICTs is the third crucial challenge for women after poverty and violence. Therefore, the consideration of gender issues and women integration in ICTs and development become more important despite the constraints and the gap between what is said and what is done. This work focuses on issues that include the use of technologies such as mobile phones by Malian women in an environment whereby tradition and modernity tackle each other. In other words, this study analyses how mobile phones, the new practices and transformations it brings in, fit in the daily life of Malian business women.

Globalmente organismos internacionais promovem e coordenam iniciativas de prevenção e redução do risco de desastres e convocam as nações para tal compromisso. No Brasil, um avanço ocorreu com a instituição da Política Nacional de Proteção e Defesa Civil por meio da Lei 12.608/2012, que dentre outros aspectos, reorienta a gestão do risco de desastre que compreende três ações distintas e inter-relacionadas: prevenção, mitigação e preparação. Estas ocorrem de forma multissetorial nos níveis federal, estadual e municipal e exigem ampla participação comunitária. Neste contexto entram as Tecnologias de Informação Móveis e Sem Fio, cujo desenvolvimento nas últimas duas décadas as colocou em evidência como importantes recursos para assistência em cenários inesperados e disruptivos e, desempenham um papel cada vez mais positivo como ferramentas de comunicação de risco de desastres. Este estudo objetiva analisar como ocorre o processo comunicacional na gestão do risco de inundações, por meio do uso de Tecnologias Móveis e sem Fio, entre as instituições de defesa civil e a população estabelecida em áreas inundáveis. Busca, ainda, identificar a percepção dos atores sobre a qualidade das informações de alertas recebidos por meio de tecnologias móveis e as vantagens e desvantagens do seu uso na comunicação de risco. Como estratégia de pesquisa foi realizado um estudo de caso único em uma cidade no interior do Estado de Santa Catarina que, quase que anualmente, enfrenta a problemática de inundações. O estudo conclui que as tecnologias móveis e as mídias sociais móveis são ferramentas eficazes e eficientes na comunicação de risco, pois ampliam as possibilidades de acesso e disseminação de alertas; estimulam, facilitam e impulsionam a interação da população com os órgãos de proteção e defesa civil e contribuem positivamente para a mobilização perante o desastre, pois agilizam a transmissão da informação, favorecendo o planejamento para a evacuação de áreas de risco. Já, as notícias falsas transmitidas por mídias móveis e o risco de falta de conexão e energia caracterizam algumas das desvantagens de uso dessas tecnologias. / The combination of severe weather events and natural disasters has raised concerns in all societies. Globally, international agencies promote and coordinate disaster risk reduction and prevention initiatives and call on nations for such a commitment. In Brazil, a breakthrough occurred with the institution of the National Protection and Civil Defense Policy through Law 12,608/2012, which, among other aspects, reorients disaster risk management, which comprises three distinct and interrelated actions: prevention, mitigation and preparation. These occur in a multisectoral manner at the federal, state and municipal levels and require broad community participation. Mobile and Wireless Information Technologies are emerging in this context, whose development over the last two decades has highlighted them as important resources for assistance in unexpected and disruptive scenarios and play an increasingly positive role as tools for communicating disaster risk. This study aims to analyze how the communication process occurs in flood risk management, through the use of Mobile and Wireless Technologies, between civil defense institutions and the population established in flood areas. It also seeks to identify the perception of the actors about the quality of the information received from mobile technologies and the advantages and disadvantages of their use in risk communication. As a research strategy, a single case study was carried out in a city in the interior of the State of Santa Catarina, which almost annually faces the problem of floods. The study concludes that mobile technologies and mobile social media are effective and efficient tools in risk communication, since they increase the possibilities of access and dissemination of alerts; stimulate, facilitate and boost the interaction of the population with the civil protection and defense organs and contribute positively to the mobilization in the face of the disaster, since they speed up the transmission of information, favoring the planning for the evacuation of areas at risk. Already, the false news transmitted by mobile media and the risk of lack of connection and energy characterize some of the disadvantages of using these technologies.
