Blockchain for Financial Inclusion and Mobile Financial Services : A study in sub-Saharan AfricaDanho, Sargon, Habte, Yonathan January 2019 (has links)
Financial services have historically been offered by central entities which has put financial systems in the control of a number of central parties. Some argue that this centralization has contributed to a more unequal distribution of wealth. However, during more recent time with the emergence of blockchain, traditional perspectives on transparency and democratization have shifted. Increasing financial inclusion has been highlighted as a crucial step in decreasing poverty levels and blockchain has been discussed as a technology with a potential to make a difference in this ambition. This study will focus on sub-Saharan Africa where 550 million individuals lack access to financial services despite having access to mobile phones. As a consequence of this, mobile financial services boomed in sub-Saharan Africa, starting in Kenya. This study will therefore focus on mobile financial services and more precisely on the perceived usefulness of blockchain technology for the mobile financial services. Furthermore, the study aims to explore what role blockchain can play in further increasing financial inclusion in the region. This was done by conducting several interviews with people representing start-ups, government agencies, telco companies during a research trip to South Africa and by participation in the Blockchain Africa Conference 2019 in Cape town. The findings from the research show that blockchain is perceived as useful for mobile financial services, mainly because of its ability to reduce costs by removing intermediaries, to automate processes and to create decentralized trust. However, it was also found that the usefulness is negatively affected today due to the lack of common protocols and definitions, which makes it difficult for blockchain to yet make a real difference in increasing financial inclusion. / Finansiella tjänster har historiskt sätt tillhandahållits med hjälp av centraliserad datalagring genom pålitliga intermediärer såsom banker och försäkringsbolag. Detta har satt det finansiella systemet i kontroll av några få centrala aktörer vilket somliga menar har ökat den ekonomisk ojämlikheten. På senare tid, i samband med blockkedjeteknologins framväxt, har synen på demokrati och transparens skiftat. Ökad finansiell inkludering har lyfts fram som avgörande för att minska fattigdomen. Blockkedjeteknologin har framhävts att ha potential att göra skillnad i detta arbete. Denna studie fokuserar på Subsahariska Afrika där 550 miljoner individer saknar tillgång till finansiella tjänster trots att de har tillgång till mobiltelefoner. Att erbjuda mobila finansiella tjänster är viktigt för att möjliggöra finansiell inkludering. Studien ämnar därför att undersöka upplevd användbarhet av blockkedjeteknologi för mobila finansiella tjänster och hur tekniken kan utöka finansiell inkludering i kontinenten. Detta har delvis gjorts genom en forskningsresa till Sydafrika där flertalet intervjuer utfördes med personer som representerar startupbolag, regeringen, telekombranschen och den akademiska världen. Resultaten från studien visar att blockkedjeteknologin upplevs vara användbar för mobila finansiella tjänster, främst på grund av dess förmåga att sänka kostnaderna genom att ta bort mellanhänder, automatisera processer samt skapa säkra decentraliserade system. Däremot måste standardiserade protokoll och definitioner måste utvecklas innan detta kan realiseras. Fram till dess kommer det att vara svårt för blockkedjeteknolgi att göra en verklig skillnad i ökad finansiell inkludering.

Expectations and Obstacles of Smart Services:: The Role of Transparency, Privacy and Trust for the Acceptance and Adoption of Smart ServicesHädecke, Kenneth 20 July 2022 (has links)
Over the last decades the use of technology has drastically increased and its influence on services has been rising constantly (Meuter et al., 2005; Bitner et al., 2010; Rust and Huang, 2014). The digital revolution has paved the way for new predictive service concepts that are linked to the contents of this dissertation. Despite the many studies that have been conducted (e.g., Allmendinger and Lombreglia, 2005; Hubert et al., 2019; Kabadayi et al., 2019; Kashef et al.,2021; Klein et al., 2018; Timeus et al., 2020) and the amount of literature on this subject (e.g., Rehse et al., 2016; Pena-Rios et al., 2018; Paschou et al., 2018), there are still many gaps in the current status of its research. The industry is constantly introducing new phraseology to create unique selling propositions, such as service 4.0 in the automotive sector, which has not yet been scientifically defined. Against this backdrop, the first step of this dissertation was to define the wording “service 4.0” in the automotive context and to compare it with the fairly more common wording of “smart service”. By analysing interviews with knowledgeable respondents, the first out of four research papers describe the characterising components of service 4.0 and demands a unification of the wordings service 4.0 and smart services. Therefore, the further studies and associated papers use the expression 'smart services'. Additionally, the first study gives an overview of what practitioners expect of this kind of service in the automotive context.
However, the development and implementation of new services require knowledge about customers’ needs and expectations to establish the services successfully. This leads to the question, what do customers actually expect of a predictive service in the automotive sector or a car workshop? Research paper II followed these thoughts and analysed interviews and a group discussion with consumers of different ages, genders, levels of education and origins in Germany. Based on the expectations, it introduced five categories of consumers’ and provides an overview of obstacles to the acceptance of smart services. The results of the qualitative studies reveal that many of the obstacles and expectations are concerned with data safety and trust. Furthermore, the results show that perceived transparency seems to influence trust.
While the results of research paper II show the different influencing factors of trust in connection with the acceptance of smart services, research paper III tries to develop a new framework that reflects these relations. To do so, a quantitative study was conducted based on a sample of more than 1,000 consumers’ who answered the questionnaire. Based on the Technology Acceptance Model, the developed framework explains the connection between perceived transparency, privacy risks, perceived security, perceived control and initial trust. Furthermore, the results help to better understand the variance of perceived usefulness by employing the construct of initial trust. Moreover, the construct of perceived firm transparency has a strong influence on initial trust.
The final research paper employed a qualitative research design to describe in detail the obstacles to the acceptance of smart services. It explored two main obstacle categories and one subcategory that describe why customers reject smart services and what their concerns are. Finally, research paper IV used an experiment to explore whether video clips can be used to increase the perceived firm transparency and control. The results of the empirical study show, that video clips seem to increase the perceived firm transparency and control. Therefore, the combined results of research papers III and IV could be a powerful tool for practitioners enabling them to increase initial trust and acceptance of smart services through the use of video clips. This article presents an overview the conducted studies and summarizes the results. Furthermore, it summarizes the underlying theories and builds a theoretical framework.
All in all, this dissertation deepens the understanding of the acceptance of smart services using the example of the automotive sector, and the results should be valuable from a theoretical as well as from a practical point of view.:Summary I

Does community matter? Social and cultural influences on acceptance and use of collaborative educational technologies.Osman, Negla, Köhler, Thomas January 2013 (has links)
The recent advances in information and communication technologies (ICTs) over the past two decades have influenced many aspects of live ([19] and [7]). These advances make the issue of acceptance of ICTs a topic of increasing importance, particularly in educational research and practice [18]. Many studies have been conducted to understand, explain, and predict the issue of acceptance and use of new technologies. Fortunately, these studies have resulted in several serious theoretical developments [9]. Overall understanding of the role of culture and social norms in influencing acceptance and use of education technologies, particularly collaborative and interactive technologies such as the internet, can facilitate the successful implementation and use of these technologies in the educational context. This study concentrates on providing insight into the influence of culture and social processes on staff members’ acceptance and use of educational technology, namely the internet at Khartoum state universities (KSUs). Specifically, the study aims to identify the influential role of these factors on acceptance and the use of the internet as a helpful collaborative educational technology. To achieve this aim, the study adopts technology acceptance model (TAM), which is modified (i.e. extended) with Hofstede’s cultural dimensions (mainly uncertainty avoidance and masculinity). With the help of a structural equation model (SEM), the data assessment demonstrates the validity of the model and proves that social influence process and cultural factors have significant (direct and moderate) influence on staff members’ acceptance and use of internet technology for teaching and academic activities – i.e. the authors are able to assert that community matters in the adoption of these new ICTs. The article concludes by offering important implications and recommendations for both research and practice.

The Effects of National Culture Values on Consumer Acceptance of E-commerce : The Swedish CaseWahlberg, Arvid January 2015 (has links)
A large amount of research has been conducted in order to seek explanations that clarify e-commerce acceptance throughout the world; however, there is a gap in the research as to how e-commerce acceptance is attributable to national culture. Two previous studies (Yoon, 2009), (Capece, et al., 2013) used Hofstede’s five dimensions of national culture in conjunction with the Technology Acceptance Model (TAM) as a means to filling this gap with perspectives on low-acceptance populations (China in 2008 and Italy in 2013). The study presented in this paper is a continuation of the previous work, offering a perspective on a high-acceptance population (Sweden). The main research question is about investigating how Swedish e-commerce acceptance is related to national culture, and the answer is sought by probing on the Swedish perspective of e-commerce in the light of the TAM, e-commerce trust, and Hofstede’s five dimensions of national culture in an online survey. The data is analyzed using Structural Equation Modeling (SEM), and compared to the findings of the Chinese and Italian precursors. Furthermore, an attempt is made to explain the contrast between the comparably high e-commerce acceptance in Sweden to the lower degrees of acceptance in China and Italy.

Conception d’outils d’échafaudage numériques et analyse de leur influence sur le processus de résolution de problèmes complexes auprès des apprenants universitaires en gestionTremblay, Chantal 07 1900 (has links)
La résolution de problèmes complexes (RPC) est une compétence du 21e siècle essentielle chez les gestionnaires. Or, bien que les programmes en gestion visent à développer cette compétence, de nombreux diplômés récents éprouvent des lacunes lorsqu’ils arrivent sur le marché du travail. Si leur manque de connaissances disciplinaires et leur faible niveau de compétences métacognitives peuvent les expliquer en partie, ces lacunes sont aussi possiblement attribuables aux méthodes pédagogiques couramment utilisées en gestion, qui n’enseignent pas explicitement un processus de RPC.
Considérant l’importance d’enseigner explicitement une démarche générale de RPC et le développement des compétences métacognitives, cette recherche est fondée sur la théorie de l’échafaudage. Ainsi, des outils d’échafaudage numériques visant à assister temporairement les apprenants, afin qu’ils puissent internaliser un processus de RPC et développer leurs compétences métacognitives, ont été intégrés à une application numérique utilisée par des apprenants de 1er cycle universitaire en gestion.
Cette recherche mixte a permis d’évaluer l’influence de ces outils d’échafaudage numériques sur l’apprentissage de la RPC et le développement de compétences métacognitives, de comprendre leur influence durant le processus de résolution, et de décrire l’intention d’utilisation des apprenants. Les résultats quantitatifs montrent que l’accès aux outils a amélioré la performance de RPC à une reprise et soutenu le développement de la compétence métacognitive de planification. Les résultats qualitatifs suggèrent que les apprenants considéraient que les outils les aidaient à améliorer la qualité de leurs évaluations, mais ils ne percevaient pas qu’ils visaient aussi à développer leurs compétences métacognitives.
Les résultats suggèrent que ces apprenants peuvent être qualifiés de novices quant à leur compétence de RPC. En effet, ils semblent accorder un temps insuffisant à l’analyse de la situation problème, n’évaluent pas les autres solutions possibles, ne considèrent pas les conséquences négatives de leur solution et mobilisent peu leurs compétences métacognitives de monitoring et d’autocontrôle et d’autoévaluation.
La perception d’utilité serait corrélée avec la perception de pertinence, d’amélioration de la qualité du travail et du caractère agréable des OÉN. Considérant la perception de facilité d’utilisation fortement élevée parmi tous les participants, cela suggère que l’intention d’utilisation serait principalement liée à la perception d’utilité Les résultats suggèrent que ces OÉN seraient davantage pertinents en formation à distance, plutôt qu’en présentiel. Les questions incitatives influenceraient davantage le processus de RPC, comparativement à une liste de vérification et des vidéos de solutions d’experts.
Plusieurs recommandations ont été élaborées pour améliorer la conception et l’usage des OÉN. Les apprenants doivent être formés par leur enseignant à utiliser les OÉN, qui doit leur montrer la pertinence et la manière de les exploiter adéquatement. Les OÉN doivent offrir un niveau de soutien cognitif suffisant et constant à toutes les étapes de la RPC. L’application doit être dotée de fonctionnalités qui permettent de comprendre pourquoi les outils doivent être mobilisés. Les concepteurs doivent considérer les déterminants qui influencent la PU pour susciter leur usage.
En somme, bien que cette recherche comporte plusieurs limites, notamment une collecte de données pendant la COVID-19, elle contribue significativement à la littérature grâce à ses recommandations visant la conception et l’usage des outils d’échafaudage numériques en enseignement supérieur. / Complex problem-solving (CPS) is an essential 21st century skill for all managers. Although most of the business administration programs aim to develop this skill, many graduates still feel gaps when they enter the labour market. If their lack of content knowledge and their low level of metacognitive skills can explain in part these gaps, they might also be caused by the teaching methods commonly used in business administration education. Indeed, these methods do not demonstrate a process for CPS explicitly.
Considering the importance of teaching a CPS process explicitly and the development of metacognitive skills, this research is based on the scaffolding theory. Thus, digital scaffolds aiming at temporary assisting learners to internalize a CPS process and to develop their metacognitive skills were integrated to a digital application that has been used by undergrad students in business administration.
By using a mix method, this research evaluated the influence of these scaffolds on the learning of CPS and the development of metacognitive skills. It also contributes to understand how these scaffolds influence learners during their problem-solving process and to describe their intention of use. Quantitative results indicate that access to scaffolds improved the performance on one assessment and show that it led to the development of the planning metacognitive skill. Qualitative results suggest that learners considered that these scaffolds were helping them to improve the quality of their assessments, although they did not perceive that these tools were also designed to develop their metacognitive skills.
The results suggest that these learners can be called novices regarding their CPS skill. Indeed, they seem to allocate insufficient time to analyze the situation, they do not evaluate alternative solutions nor consider the negative consequences of their chosen solution and they insufficiently used their metacognitive skills of monitoring, self-regulation, and self-evaluation.
The perceived utility of these scaffolds seem correlated with the perceived relevance, the perceived output quality, and the perceived enjoyment of using them. Considering a high perceived ease-of-use amongst all participants, this suggests that intention of use is mostly linked to the perceived utility. The results suggest that these scaffolds are more relevant in online learning, compared to face-to-face learning. Prompts, compared to a check list and videos of experts’ solutions, seem to have more influence on CPS process.
Several recommendations are proposed to improve the design and the use of digital scaffolds. Learners should be trained by their teacher to use them efficiently. Teachers should demonstrate their relevance and the manner that students should use them for learning purposes. Digital scaffolds should offer a sufficient cognitive support throughout the CPS process. The application should include functions that allow students to understand why these should use these tools. Designers should consider the determinants of perceived usefulness when they conceptualize scaffolds to foster their usage.
In sum, although this research has some limitations, notably a data collection done during the COVID-19 pandemic, it significantly contributes to the literature by proposing several recommendations aiming at improving the design and the use of digital scaffolds in higher education.

A framework for the implementation of e-procurement practices in the South African public sectorMothibi, Gloria Mokgalagadi 07 1900 (has links)
Ph. D. (Department of Business Administration, Faculty of Management Sciences), Vaal University of Technology. / The use of technology in supply chain management has increased over the years. Procurement is one of the primary supply chain management areas where the use of technology has gained momentum. This has been realised through the use of e-procurement systems. However, the adoption and implementation of e-procurement can be achieved more effectively if available models of technology adoption are taken into consideration. This study tested a conceptual framework integrating the Technology Acceptance Model (TAM) and the Unified Theory of the Acceptance and use of Technology (UTAUT) in the implementation of e-procurement practices in the South African public sector. Although there are several studies that have focused on procurement in the public sector in South Africa, there is no evidence of studies that extended the use of the TAM and the UTAUT within the public sector in South Africa. This study was conducted to fill this gap by proposing a framework combining the TAM and UTAUT and modelling their role in the adoption of e-procurement in the public sector.
The study adopted a survey design and a quantitative research approach was used to evaluate relationships between different variables. The final sample for this study consists of 263 supply chain management (SCM) practitioners drawn from the public sector in the Gauteng Province, South Africa. A self-completion survey questionnaire was used to gather data to measure the eight constructs of the TAM and UTAUT.
An Exploratory Factor Analysis (EFA) procedure was performed to assess the factor structure of the data collected in the study. Descriptive statistics were applied to examine the demographic profile of respondents and the perceptions of respondents towards the research constructs. Pearson correlations were used to test relationships and regression analysis was used to test the hypotheses. In the EFA, two new factors, labelled as Personal Competence and External Assistance, were identified. The results of the hypotheses tests showed that five factors, namely: perceived use, self-efficacy, facilitating conditions, personal competence and external assistance significantly predicted attitudes towards the use of e-procurement systems. However, perceived ease of use was statistically insignificant. The results further show that attitudes towards system use significantly predict behavioural intention, which in turn significantly influences actual e-procurement system use.
The theoretical framework fusing the TAM and UTAUT models provides useful insights for other researchers and adds valuable knowledge to the factors that might contribute to the adoption of e-procurement in the South African public sector. The study further makes significant contributions to SCM professionals in the public sector. It reiterates the challenges faced in SCM in the public sector and then demonstrates how the adoption of e-procurement could improve the system, while reducing service delivery inequality. By indicating the factors either promoting or impeding the adoption of e-procurement in the public sector, the study provides practitioners and other decision makers in SCM with suggestions on how to facilitate more rapid adoption and circumvent the influence of irrelevant factors.
Among other things, the study recommends that to improve the adoption and continued use of e-procurement systems in the public sector in the Gauteng Province, it is necessary to customise the e-procurement system to ensure that it responds to the needs of users. In addition, it is important to increase the confidence and competence of users of the systems, providing the relevant technical infrastructure and support to users in order to positively influence their attitudes and behavioural intention towards the use of e-procurement systems.

Information Literacy Instruction in Business Schools: Factors Affecting the Adoption of Online Library Resources by Business StudentsBooker, Lorne D. 10 1900 (has links)
<p>The overall goal of this dissertation is to predict and explain how information literacy instruction (ILI) influences the adoption of online library resources (OLRs) by business students. This dissertation has two other important goals. First, this dissertation aims to assess the efficacy of active ILI and passive ILI. Second, this dissertation seeks to examine the role that OLR self-efficacy and OLR anxiety play in influencing ILI learning outcomes and the adoption of OLRs.</p> <p>To achieve these goals, a theoretical model was developed that integrates research on ILI outcomes and technology adoption. To test this model, a web-based survey was developed and administered to 337 business students at McMaster University.</p> <p>This dissertation makes several important contributions to theory. First, the findings from the analysis of the structural equation model confirm that the Technology Acceptance Model is an appropriate tool for studying the adoption of OLRs. Second, the findings indicate that amount of ILI is not a significant predictor of the adoption of OLRs. Third, though the amount of ILI was not found to be a predictor of OLR self-efficacy or OLR anxiety in the quantitative analysis, results from the qualitative analysis suggest that ILI increases self-efficacy and reduces anxiety. Fourth, the findings suggest that OLR self-efficacy and OLR anxiety are significant determinants of the adoption of OLRs where OLR self-efficacy was the strongest determinant of the adoption of OLRs. Last, consistent with Bandura’s social cognitive theory, OLR self-efficacy and OLR anxiety were found to be significantly negatively correlated; a partial mediation effect of OLR anxiety on the relationship between OLR self-efficacy and the perceived ease of use of OLRs was supported.</p> <p>This dissertation makes a contribution to practice by revealing that instructors should focus on delivering higher quality ILI rather than higher amounts of ILI. In particular, training interventions should be designed to promote OLR self-efficacy among business students, especially among students who have received the least amount of ILI.</p> / Doctor of Philosophy (PhD)

A Model-Driven Approach for the Design, Implementation, and Execution of Software Development MethodsCervera Úbeda, Mario 30 July 2015 (has links)
[EN] Software development projects are diverse in nature. For this reason, software companies are often forced to define their methods in-house. In order to define methods efficiently and effectively, software companies require systematic solutions that are built upon sound methodical foundations. Providing these solutions is the main goal of the Method Engineering discipline.
Method Engineering is the discipline to design, construct, and adapt methods, techniques, and tools for the development of information systems. Over the last two decades, a lot of research work has been performed in this area. However, despite its potential benefits, Method Engineering is not widely used in industrial settings. Some of the causes of this reality are the high theoretical complexity of Method Engineering and the lack of adequate software support.
In this thesis, we aim to mitigate some of the problems that affect Method Engineering by providing a novel methodological approach that is built upon Model-Driven Engineering (MDE) foundations. The use of MDE enables a rise in abstraction, automation, and reuse that allows us to alleviate the complexity of our Method Engineering approach. Furthermore, by leveraging MDE techniques (such
as metamodeling, model transformations, and models at runtime), our approach supports three phases of the Method Engineering lifecycle: design, implementation, and execution. This is unlike traditional Method Engineering approaches, which, in general, only support one of these phases.
In order to provide software support for our proposal, we developed a Computer-Aided Method Engineering (CAME) environment that is called MOSKitt4ME. To ensure that MOSKitt4ME offered the necessary functionality, we identified a set of functional requirements prior to developing the tool. Then, after these requirements were identified, we defined the architecture of our CAME environment, and, finally, we implemented the architecture in the context of Eclipse.
The thesis work was evaluated by means of a study that involved the participation of end users. In this study, MOSKitt4ME was assessed by means of the Technology Acceptance Model (TAM) and the Think Aloud method. While the TAM allowed us to measure usefulness and ease of use in a subjective manner, the Think Aloud method allowed us to analyze these measures objectively. Overall, the results were favorable. MOSKitt4ME was highly rated in perceived usefulness and ease of use; we also obtained positive results with respect to the users' actual performance and the difficulty experienced. / [ES] Los proyectos de desarrollo de software son diversos por naturaleza.

Para poder definir métodos de forma efectiva y eficiente, las compañías necesitan soluciones sistemáticas que estén definidas sobre unos fundamentos metodológicos sólidos. Proporcionar estas soluciones es el principal objetivo de la Ingeniería de Métodos.
La Ingeniería de Métodos es la disciplina que aborda el diseño, la construcción y la adaptación de métodos, técnicas y herramientas para el desarrollo de sistemas de información. Durante las dos últimas décadas, se ha llevado a cabo mucho trabajo de investigación en esta área. Sin embargo, pese a sus potenciales beneficios, la Ingeniería de Métodos no se aplica ampliamente en contextos
industriales. Algunas de las principales causas de esta situación son la alta complejidad teórica de la Ingeniería de Métodos y la falta de un apropiado soporte software.
En esta tesis, pretendemos mitigar algunos de los problemas que afectan a la Ingeniería de Métodos proporcionando una propuesta metodológica innovadora que está basada en la Ingeniería Dirigida por Modelos (MDE). El uso de MDE permite elevar el nivel de abstracción, automatización y reuso, lo que posibilita una reducción de la complejidad de nuestra propuesta. Además, aprovechando técnicas de MDE (como por ejemplo el metamodelado, las transformaciones de modelos y los
modelos en tiempo de ejecución), nuestra aproximación da soporte a tres fases del ciclo de vida de la Ingeniería de Métodos: diseño, implementación y ejecución. Esto es a diferencia de las propuestas existentes, las cuales, por lo general, sólo dan soporte a una de estas fases.
Con el objetivo de proporcionar soporte software para nuestra propuesta, implementamos una herramienta CAME (Computer-Aided Method Engineering) llamada MOSKitt4ME. Para garantizar que MOSKitt4ME proporcionaba la funcionalidad necesaria, definimos un conjunto de requisitos funcionales como paso previo al desarrollo de la herramienta. Tras la definción de estos requisitos, definimos la arquitectura de la herramienta CAME y, finalmente, implementamos la arquitectura en el contexto de Eclipse.
El trabajo desarrollado en esta tesis se evaluó por medio de un estudio donde participaron usuarios finales. En este estudio, MOSKitt4ME se evaluó por medio del Technology Acceptance Model (TAM) y del método Think Aloud. Mientras que el TAM permitió medir utilidad y facilidad de uso de forma subjetiva, el método Think Aloud permitió analizar estas medidas objetivamente. En general, los
resultados obtenidos fueron favorables. MOSKitt4ME fue valorado de forma positiva en cuanto a utilidad y facilidad de uso percibida; además, obtuvimos resultados positivos en cuanto al rendimiento objetivo de los usuarios y la dificultad experimentada. / [CA] Els projectes de desenvolupament de programari són diversos per naturalesa.

An Ethnography of Direct-to-Consumer Genomics [DTCG]: Design Anthropology Insights for the Product Management of a Disruptive InnovationArtz, Matthew 08 1900 (has links)
Direct-to-consumer genomics (DTCG) health testing offers great promise to humanity, however to date adoption has lagged as a result of consumer awareness, understanding, and previous government regulations restricting DTCG companies from providing information on an individual's genetic predispositions. But in 2017 the broader DTCG market which also includes genealogical testing demonstrated exponential growth, implying that DTCG is starting to diffuse as an innovation. To better understand the sociocultural forces affecting diffusion, adoption, and satisfaction, qualitative ethnographic research was conducted with DTCG genealogy and health consumers. The data was qualitatively analyzed using thematic analysis to understand the similarities and differences in beliefs, attitudes, intentions, and mediating factors that have influenced consumers. Design anthropology theory and methods were used to produce ethnographically informed insights. The insights were then translated into actionable product management and business strategy recommendations.

Improving health delivery in rural communities through the use of mobile phones : a case study in WindhoekIyawa, Gloria Ejehiohen 11 1900 (has links)
Poor health care delivery in rural communities is a major problem facing the health sector in Namibia.
Patients who visit rural communities often wait on queues for several hours every day before they can
be examined by a medical practitioner. This is detrimental to the health care process and impacts
negatively on the efficiency and effectiveness of the sector. Mobile phones can however be employed
as tools to improve work processes in such hospitals and as a result improve health care delivery in
rural communities.
The purpose of this study was to investigate the health care services provided to patients at Outpatient
Departments (OPDs) in rural hospitals through the use of data collection instruments such as
interviews, questionnaires, document analysis, expert validation and photographs in order to compile a
Mobile Health Service Framework (MHSF) to improve healthcare delivery processes in OPDs. From
an interpretive paradigm perspective, the qualitative design was used together with a case study
approach. Three hospitals in rural communities were used as case studies. These were Okuryangava
Hospital, Katutura Hospital and Khomasdal Hospital. Interviews were conducted and questionnaires
distributed to the participants. The findings revealed that there is a high concentration of mobile phone
usage in rural communities and there is a high usage of the SMS feature on such mobile phones. / Computing / M. Sc. (Computing)
