Service-oriented Context-aware Framework
Location- and context-aware services are emerging technologies in mobile and
desktop environments, however, most of them are difficult to use and do not
seem to be beneficial enough. Our research focuses on designing and creating a
service-oriented framework that helps location- and context-aware,
client-service type application development and use. Location information is
combined with other contexts such as the users' history, preferences and
disabilities. The framework also handles the spatial model of the environment
(e.g. map of a room or a building) as a context. The framework is built on a
semantic backend where the ontologies are represented using the OWL description
language. The use of ontologies enables the framework to run inference tasks
and to easily adapt to new context types. The framework contains a
compatibility layer for positioning devices, which hides the technical
differences of positioning technologies and enables the combination of location
data of various sources
Using Privacy Calculus Theory To Assess Users´ Acceptance Of Video Conferencing Apps During The Covid-19 Pandemic
Dissertation presented as the partial requirement for obtaining a Master's degree in Information Management, specialization in Information Systems and Technologies ManagementVideoconferencing (VC) applications (apps) are getting notable attention worldwide, from common citizens to
professionals as an alternative to vis-Ã -vis communication specifically during COVID-19. The growth of VC apps
is expected to rise even more in the future with the prediction that widespread adoption of remote work will
continue to hold even after the pandemic. This research investigates the key drivers for individuals’ intentions
into continuing to use this technology in professional settings. Considering the importance of professionals’
perceptions of privacy in professionals’ settings, this study proposes a conceptual model rooted in the
theoretical foundations of privacy calculus theory, extended with the conceptualization of privacy concerns for
mobile users (MUIPC), ubiquity, and theoretical underpinnings from social presence theory. The conceptual
research model was empirically tested by using data collected from a survey of 487 actual users of videoconferencing
apps across Europe. Structural equation modeling (SEM) is performed to test the model. The
study revealed several findings (1) perceived value in using VC apps motivates the professionals to continue
using VC apps and shapes their perception as they evaluate the risk-benefit trade-off they are making when
using VC apps. (2) professionals’ indeed form and articulate their own assessment of value based on the
perceived risks and benefits associated with using VC apps. However, professionals' perceptions of value are
strongly influenced by potential benefits received from using VC apps than by potential risks associated with
using VC apps. (3) professionals’ perceived risk is determined by MUIPC and trust. (4) professionals’ perceived
benefits are shaped by ubiquity and social presence. For researchers, this study highlights the usefulness of
integrating privacy calculus theory, social presence theory and trust in studying the individuals’ behavioral
intentions towards new technologies. For practitioners, understanding the key determinants is pivotal to
design and build mobile video-conferencing apps that achieve higher consumer acceptance and higher rates of
continued usage of VC apps in professional settings
Interpreting infrastructure: Defining user value for digital financial intermediaries.
The 3DaRoC project is exploring digital connectivity and peer-to-peer relationships in financial
services. In the light of the near collapse of the UK and world financial sector, understanding and
innovating new and more sustainable approaches to financial services is now a critical topic. At the
same time, the increasing penetration and take-up of robust high-speed networks, dependable peerto-
peer architectures and mobile multimedia technologies offer novel platforms for offering financial
services over the Internet. These new forms of digital connectivity give rise to opportunities in doing
financial transactions in different ways and with radically different business models that offer the
possibility of transforming the marketplace. One area in the digital economy that has had such an
effect is in the ways that users access and use digital banking and payment services.
The impact of the new economic models presented by these digital financial services is yet to be fully
determined, but they have huge potential as disruptive innovations, with a potentially transformative
effect on the way that services are offered to users. Little is understood about how technical
infrastructures impact on the ways that people make sense of the financial services that they use, or
on how these might be designed more effectively. 3DaRoC is exploring this space working with our
partners and end users to prototype and evaluate new online, mobile, ubiquitous and tangible
technologies, exploring how these services might be extended.Executive Summary: Drawing from Studies of Use - the value, use and interpretation of infrastructure in digital intermediaries to their users. The UK economy has a huge dependence on financial services, and this is increasingly based on digital platforms. Innovating new economic models around consumer financial services through the use of digital technologies is seen as increasingly important in developed economies. There are a number of drivers for this, ranging from national economic factors to the prosaic nature of enabling cheap, speedy and timely interactions for users. The potential for these new digital solutions is that they will allay an over-reliance on the traditional banking sector, which has proved itself to be unstable and risky, and we have seen a number of national policy moves to encourage growth in this sector. Partly as a result of the 2008 banking crisis, there has been an explosion in peer-to-peer financial services for non-professional consumers. These organisations act as intermediaries between users looking to trade goods or credit. However, building self-sustaining or profitable financial services within this novel space is itself fraught with commercial, regulatory, technical and social problems. This document reports on the value, use and interpretation of infrastructure in digital intermediaries to their users, describing analysis of contextual field studies carried out in two retail digital financial intermediary organisations: Zopa Limited and the Bristol Pound. It forms the second milestone document in the 3DaRoC project, developing patterns of use that have arisen on the back of the technical infrastructures in the two organisations that form cases for examination. Its purpose is to examine how the two different technical infrastructures that underpin the transactions that they support–composed of the back-office hardware and software, data structures, the networking and communications technologies used, supported consumer devices, and the user interfaces and interaction design–have provided opportunities for users to realise their financial and other needs. While we orient towards the issues of service use (and its problems), we also examine the activities and expectations of their various users. Our research has involved teams from Lancaster University examining Zopa and Brunel University focusing on the Bristol Pound over approximately a one-year period from October 2013 to October 2014. Extensive interviews, document analysis, observation of user interactions, and other methods have been employed to develop the process analyses of the firms presented here. This report comprises of three key sections: descriptions of the user demographics for Zopa and the Bristol Pound, a discussion about the user experience and its role in community, and an examination of the role of usage data in the development of these a products. We conclude with final analytical section drawing preliminary conclusions from the research presented.The 3DaRoC project is funded by the RCUK Digital Economy ‘Research in the Wild’ theme (grant no.

The Efficacy of Habitat Conservation Assistance Programs for Family Forest Owners in Vermont
The future of Vermont’s 1.8 million hectares (4.5 million acres) of forest habitat will be largely determined by the decisions of family forest owners, who collectively own 60% of the state’s forested land. To promote management for wildlife habitat, government agencies and non-governmental partnerships provide technical and financial support to family forest owners in the form of conservation assistance programs. In Chapter 1, I qualitatively compared the efficacy of two types of conservation assistance programs available in Vermont: traditional programs offered through the Natural Resources Conservation Service, and a simplified, accelerated program offered through a non-governmental partnership called Woods, Wildlife, and Warblers. By conducting interviews with 20 Vermont family forest owners, I identified common motivation and barrier themes and compared these themes across programs using the Transtheoretical Model’s Stages of Change. Most motivations and barriers were described by landowners across all Stages of Change, but two motivations (professional recommendations and straightforward applications) and one barrier (independent forest management values) varied by either Stage of Change, program type, or both. I used the findings from the interviews to develop a mail survey, which was used to quantify patterns regarding motivations and barriers towards three habitat conservation actions: 1) arranging for a forestry professional to walk the land, 2) applying for cost-share funds, and 3) making a patch cut. The results from this survey, which was sent to 2,122 randomly selected Vermont family forest owners and had a cooperation rate of 38%, are presented in Chapter 2. Using logistic regression models, I identified multiple significant motivations or barriers for each of the three actions. Additionally, I used contingency tables to compare respondents’ levels of agreement for these motivations and barriers – as well as their level of trust for various information sources – with their Stage of Change. Overall, levels of agreement varied significantly across one or more Stages of Change for all motivations and barriers, and trustworthiness varied for 13 out of 14 information sources. Across both chapters, I provide recommendations to increase program efficacy with an emphasis on program attributes and tailored messaging
Spending time with money: from shared values to social connectivity
This article has been made available through the Brunel Open Access Publishing Fund.There is a rapidly growing momentum driving the development of mobile payment systems for co-present interactions, using near-field communication on smartphones and contactless payment systems. The design (and marketing) imperative for this is to enable faster, simpler, effortless and secure transactions, yet our evidence shows that this focus on reducing transactional friction may ignore other important features around making payments. We draw from empirical data to consider user interactions around financial exchanges made on mobile phones. Our findings examine how the practices around making payments support people in making connections, to other people, to their communities, to the places they move through, to their environment, and to what they consume. While these social and community bonds shape the kinds of interactions that become possible, they also shape how users feel about, and act on, the values that they hold with their co-users. We draw implications for future payment systems that make use of community connections, build trust, leverage transactional latency, and generate opportunities for rich social interactions
Implications of cultural differences between West and East on User Experience and Interaction Design
Psychologists have until lately been rather likeminded when it comes to how the human brain is interpreting and processing different types of information. We react in certain ways when exposed to certain information but considering those reactions stem from experiments mainly conducted on Americans is not something that is considered to be of importance. Whereas these statements tend to hold true for many aspects, lately some studies executed on people from different countries with very different cultural background have investigated if those psychological rules indeed are applying on every individual being (Henrich, Heine, & Norenzayan, 2010). When it comes to how Westerners and Easterners (especially Americans and Chinese) process information, remarkably enough plenty of differences were discovered. This thesis will discuss those differences and attempt to analyse whether or not those inequalities could be used to understand how we may adjust technical products when it comes to designing products, mainly focusing on interaction design and user experience. It was found that there may be several relations to cultural background and that they might affect preference towards user interfaces. Even though the amount of participants lacked in some user groups, and more test subjects would be needed, some noticeable patterns were still discovered. It seems like a preference towards more interactivity and more complex and colourful design may be more appreciated by the typical Chinese user, while it seems like it’s basically the opposite for the typical western user
