D.Litt. et Phil. / The purpose of this research was to determine the status of e-readiness of Small and Medium-Sized enterprises (SMEs) in the ICT sector in Botswana with respect to information access using ICTs for competitiveness in the local and international markets. The population of study consisted of key informants from 114 SMEs in the ICT sector in Gaborone and Francistown, the capital city and the second largest city of Botswana respectively. The official list of ICT companies provided by the government of Botswana was used as the sampling frame. The research used a two-phase design - the preliminary survey and the main survey of the project. The preliminary survey consisted of two stages. During the first stage, a short structured questionnaire was administered to a census of 114 key informants from SMEs in the ICT sector. During the second stage, six focus group discussions were used to collect data from key stakeholders in the ICT sector who included representatives from: ICT companies, ICT professional body in Botswana, government utility corporations, academia and the business community. The participants in the focus group discussions involved representatives from 55 SMEs who were identified like in the first stage using the government official list of SMEs in Botswana. The quantitative data collected through questionnaire were analysed using SPSS while the qualitative data collected through focus group discussions and in-depth interviews were analysed using thematic tables. The results were represented using tables, pie charts, categories and narrations. The results of the preliminary survey of the project were used to characterise the ICT sector in terms of its size, key players, nature of businesses, products and services traded in, distribution of business by location and the issues that affected the sector. This characterisation was important in two main respects. Firstly, it provided a clear roadmap for the design of the main survey of the research since little information existed on the subject of e-readiness on Botswana in general and with respect to SMEs in particular. Similarly, the government had invested a lot of resources in ICT infrastructure development and was focusing on SMEs especially those in the ICT sector to diversify the economy from the dominant diamond mining to service industry. Secondly, the results of the preliminary survey of the project supported the development of a structured interview schedule that was used during the main survey of the project. During the main survey of the research data was collected from companies that participated in the focus group discussions. From the focus group list of participants, an alphabetical name list of 55 SMEs was created. There were 43 Small-Sized and 12 Medium-Sized enterprises that were represented during the focus group discussions. For the purpose of carrying out the structured interviews, SMEs were stratified into two (Small-Sized enterprises and Medium-Sized enterprises). From the Small-Sized enterprises stratum, 20 companies were systematically selected (from the 43) taking every other member on the list. On the other hand, in the Medium-Sized enterprises stratum, all the 12 enterprises were selected for interviews because the number of respondents was small. The data collected was analysed using categories and thematic tables because it was largely qualitative. The results were presented in the form of thematic tables and through narrations. The findings from the SMEs surveyed indicated that most of the SMEs in the ICT sector in Botswana were Small-Sized enterprises that were largely not e-ready to participate in the global electronic business environment because of several impediments such as: the lack of awareness, inadequate policy and legislative framework, poor telecommunication and electricity infrastructures, poor e-commerce infrastructure, inadequate government support, the lack of access to credit, investment barriers, the lack of critical ICT skills and more. The major outcomes of the project include an exposition of the e-readiness status of SMEs in the ICT sector in Botswana, a road map that can assist the government of Botswana to establish a strong export-oriented ICT sector. The weaknesses and strengths of Botswana’s e-readiness status with regard to SMEs are brought to the fore, thus creating awareness upon which the government can design interventions that are tailored to meet Botswana’s SMEs’ specific needs. Similarly, this project provides a framework upon which the government can benchmark against its counterparts in the rest of the world in order to define its investment priorities. The project also provides baseline information which the government could use to implement appropriate policy and legislative decisions in order to enhance the e-readiness of SMEs in the ICT sector in Botswana. Finally, the new integrated e-readiness tool that was developed in this project is the first of its kind to bring the different major components of e-readiness (such as enterprise, ICT, human resources, information and external environment readiness) into a single assessment tool with great attention paid to information access. The tool is also modular in design and thus can allow specific e-readiness assessment of individual segments of society to be modelled independently of each other. The tool also enriches the qualitative aspects of e-readiness that are only minimally addressed in a few of the existing macro e-readiness assessment tools. Among the key recommendations from the research is the need for the government of Botswana to promulgate relevant policies and implement pragmatic programmes that would enable SMEs in the ICT sector in the country to use various information technologies in order to gain access to relevant information regarding access to credit, investment opportunities, partnerships, education and training opportunities so that they can effectively participate in both the local and international markets. The policy changes and programmes to be undertaken by the government should be underpinned by an effective legislative and regulatory framework that would enable the small business firms to identify, acquire, process, organise, disseminate and apply information for competitive advantage through the effective deployment and application of ICTs.

The continuing requirement for computational processing power, multi-functional devices and component miniaturization have emphasised the need for thermal management systems able to maintain the temperature at safe operating condition. The thermal management industry is constantly seeking for new cutting edge, efficient, cost effective heat transfer enhancement technologies. The aim of this study is to utilize the electron beam treatment for the improvement of the heat transfer area in liquid cooled plates and experimentally evaluate the performance. Considering the complexity of the technology, this thesis focuses on the design and production of electron beam enhanced test samples, construction of the test facility, testing procedure and evaluation of thermal and hydraulic characteristics. In particular, the current research presented in this thesis contains a number of challenging and cutting edge technological developments that include: (1) an overview of the semiconductor industry, cooling requirements, the market of thermal management systems, (2) an integral literature review of pin-fin enhancement technology, (3) design and fabrication of the electron beam enhanced test samples, (4) upgrade and construction of the experimental test rig and the development of the test procedure, (5) reduction of the experimental data and analysis to evaluate thermal and hydraulic performance. The experimental results show that the capability of the electron beam treatment to improve the thermal efficiency of current untreated liquid cooled plates is approximately three times. The highest heat transfer rate was observed for the sample S3; this is attributed to the irregularities of the enhanced structure, which improves the heat transfer area, mixing, and disturbs the thermal and velocity boundary layers. Enhancement of heat transfer for all three samples was characterised by an increase of pressure drop. The electron beam enhancement technique is a rapid process with zero material waste and cost effective. It allows thermal management systems to be produced smaller and faster, reduce material usage, without compromising safety, labour cost or the environment.

This thesis presents work carried out over a number of years within the field of railway vehicle instrumentation. The railway industry is currently moving to be more heavily “data driven”. This means that railway organisations are putting policies into place whereby decisions have to be justified based on recorded and citable data. To achieve this, the railway industry is increasingly turning to greater and greater levels of instrumentation to deliver the data on which to base these decisions. This thesis considers not only this increased requirement for data, but the frameworks and systems that must be put into place in order first to obtain it, and then to extract useful information from it. In particular the author considers the issue of contextualisation of data, where multiple datastreams may be used to provide context for, or allow more accurate and beneficial interpretation of each other in order to support better decision making. In order to obtain this data, the thesis explores, through a series of case studies, a number of options for different instrumentation system architectures. This culminates in the development of a distributed system of embedded processors arranged in an extensible modular framework to provide a rich, coherent and integrated dataset which can then be processed contextually to yield a better understanding of the railway system.

Over the past decade there has been a dramatic increase in the volume of digital content created from museum, library and archive collections but research on how this material is actually used, particularly in digital learning environments, has fallen far behind the rate of supply. In order to address this gap, this thesis examines how communities of practice (CoPs) involved in the supply and use of digital artefacts in the Higher Education sector in the UK interact with content and what factors affect this process. It focuses on a case study involving the digitisation of Shakespeare collections used in postgraduate research, and the testing of use in a range of different learning environments. This produced a number of significant findings with implications for the HE and cultural sectors. Firstly, similar patterns of artefact use were found across all users suggesting there are generic ways in which everyone interacts with digital artefacts. However, distinct forms of use did emerge which correspond with membership of particular communities of practice. Secondly, members of a CoP appear to share a particular learning style and this is influenced by the learning environment. Finally, the research indicates that a mixed method for analysing and measuring use, piloted and tested in the case study, is possible.

Over the past decade (2000-), the management of vestibular schwannomas has been in a state of flux. An increasing availability of magnetic resonance imaging has allowed clinicians to monitor tumour progression and increasingly, it has become recognised that once diagnosed, a significant proportion of lesions do not continue to grow. As a result, a number of neurotological centres have advocated conservative management as appropriate for small-medium sized tumours. Birmingham has been one of these centres, and this thesis presents data gathered over the past fifteen years that reflects this change in management, drawing upon the Birmingham Vestibular Schwannoma Database maintained by the author. The thesis addresses issues pertinent to conservative management: growth rates among observed tumours, risk factors for growth, the evolution of hearing while under observation and proposes a radiological surveillance protocol. More broadly, the thesis examines other themes important in the management of patients with vestibular schwannomas: the role of functional surgery and the possibility of rehabilitation in single-sided deafness. A number of chapters from the thesis have been published in peer-reviewed journals and are presented here in updated or amended form.

The thesis addresses the evolution of West Africa’s djembe drumming, with particular reference to the changing habitus of the djembefola. It investigates how the djembe has developed from the rural system of tribal ritualistic music intended for ceremonies to a practice enacted in the Western world, in both geographical and virtual spaces, including the social networking platform Facebook. It also highlights how, at present, djembe related activities are subject to business transactions orientated towards generation of profit for both the djembefola and other parties. Conceptually, the thesis draws on Pierre Bourdieu’s Outline of a Theory of Practice (1972), Victor Turners approach to liminality in The Forest of Symbols (1967) and The Ritual Process (1997) and the concept of cultural paradigm, as used in anthropological studies (Douglas, 1985; Rogoff et al., 2014). Additionally, it explores the implications of the evolution of djembe drumming over time for our understanding of the organisation of the djembe. This is discussed in the context of the political, economic, social and technological conditions underlying djembe practice. Empirically, the research adopts an interpretive, ethnographic and netnographic approach, comprising four case studies. Fieldwork was conducted in the Gambia and in the virtual space represented by social media. The data included material obtained through interviews with djembe teachers and students, as well as Facebook posts contributed by members of djembe related interest groups. The analysis demonstrates that, at present, the djembe habitus has entered a new phase, which the thesis identifies as a fourth cultural paradigm, concomitant with the most contemporary version of the djembe habitus.

The Internet has revolutionized the way in which people are entertained, communicate and collect information. As people increase their ability to connect with the outside world from inside their homes, they hold the power to become their own gatekeepers filtering information as they see fit. Many question whether this will weaken the power of the traditional media sources that are often seen as elitist and potentially biased. This researcher hypothesized that people who cite high credibility ratings of news media channels are more likely to use traditional media channels such as television and newspapers and people who cite low credibility ratings of news media channels are more likely to use alternate media channels such as the Internet. While the researcher was unable to reject the null hypothesis, a pattern of general mistrust of traditional news media was revealed when nearly three-fourths of respondents gave traditional media channels a "not-credible" rating. / by Katrina Herring. / Thesis (M.A.)--Florida Atlantic University, 2010. / Includes bibliography. / Electronic reproduction.

Although early predictions that an emerging 'cyberspace' could exist in separation from offline life have been largely discarded, anthropological studies of the internet have continued to find notions of 'virtual reality' relevant as individuals use these technologies to fulfil the "pledges they have already made" (Boellstorff, 2008; Miller & Slater, 2001: 19) about their own selfhood and their place in the world. There are parallels between this concept of 'virtual reality' and the on-going spiritual labour of Charismatic Christians in the UK, who seek in the context of a secularising nation to maintain a sense of presence in the “coming Kingdom” of God. The everyday production of this expanded spiritual context depends to a large extend on verbal genres that are highly gendered. For women, declarations of faith are often tied to domestic settings, personal narratives, and the unspoken testimony of daily life (e.g. Lawless, 1988; Griffith, 1997). The technologies of the internet, whose emerging genres challenge boundaries between personal and social, public and private, can cast a greater illumination on this inward-focused labour. This doctoral thesis is based on ethnographic research in four Charismatic Evangelical congregations and examination of the online practices of churchgoers. I have found that the use of the internet by Charismatic Christian women fits with wider religious preoccupations and patterns of ritual practice. Words posted through Facebook, blogs, Twitter, and other online platforms come to resemble in their form as well as their content Christian narratives of a life with meaning.

Music collections available to listeners have grown at a dramatic pace, now spanning tens of millions of tracks. Interacting with a music retrieval system can thus be overwhelming, with users offered ‘too-much-choice’. The level of engagement required for such retrieval interactions can be inappropriate, such as in mobile or multitasking contexts. Music recommender systems are widely employed to address this issue, however tend toward the opposite extreme of disempowering users and suffer from issues of subjectivity and confounds, such as the equalisation of tracks. This challenge and the styles of retrieval interaction involved are characterised in terms of user engagement in music retrieval, and the relationships between existing conceptualisations of user engagement is explored. Using listening histories and work from music psychology, a set of engagement-stratified profiles of listening behaviour are developed. A dataset comprising the playlists of thousands of users is used to contribute a user-centric approach to feature selection. The challenge of designing music retrieval for different levels of user engagement is first explored with a proof of concept, low engagement music retrieval system enabling users to casually retrieve music by tapping its rhythm as a query. The design methodology is then generalised with an engagement-dependent system, allowing users to denote their level of engagement and thus the specificity of their music queries. The engagement-dependent retrieval interaction is then explored as a component in a commercial music system. This thesis contributes the engagement-stratified profiles and metrics of listening behaviour, a corresponding design methodology for interaction, and presents a set of research and commercial applications for music retrieval.

This study focused on measuring the importance and contribution of information obtained from the library, particularly electronic information services (EIS), to success in solving clinical problems in hospitals. Three research questions with three main hypotheses were advanced and tested on clinicians in 44 hospitals in Hong Kong. The findings were tested against the framework from Wilson's (1996) existing general information behaviour model, from which a new extended model for clinicians was built. Measures of EIS were then derived from the new model. The research was broadly divided into a series of five studies in two stages: nominal group, quantitative survey, and interviews in the first stage, and randomized controlled study as well as the analyses of statistical data and computer transaction logs in the second stage. The key results in Stage I led to the studies in Stage 11. The randomized controlled study in Stage 11 attempted to reduce the barriers identified in the information environment, with a view to test the results of an educational intervention, and to confirm that the hypotheses were true given reduced barriers and the presence of enabling conditions. The effects of the interventions in this experimental study were validated and verified by statistical data and transaction logs. Corroborative evidence from the two-stage studies showed that the three main inter-connected hypotheses were supported: success in problem-solving is related to the information sources used; user satisfaction is related to success in problem-solving; and EIS use is an indicator of user satisfaction. EIS use is determined by a number of factors: the preference for EIS, the use of the library, the skills and knowledge in searching, the profession of the user and the characteristics of the work environment. Educational intervention was found to improve success in problem-solving, the attitudes, skills and knowledge in searching, the satisfaction with and use of EIS, and is an important enabling condition. The research rejected part of the first hypothesis posed that success in problem-solving is related to clinical question posed and suggests that further research is needed in this area. The study supported the extension of the general model to clinical information needs and behaviours and found new relationships. The study found an additional determinant of EIS satisfaction, the satisfaction with the information obtained. EIS satisfaction would not be changed by educational intervention alone if the information obtained was not satisfactory. On the other hand, education can improve EIS satisfaction regardless of whether the problem has been solved. Of critical importance is the time factor in determining the use (or non-use) of EIS. There is new evidence that the awareness of the user of an answer in literature is a determining factor for active searching. Borrowing the concept of opportunity cost from economic theory, the researcher relates it with the differing levels of self-efficacy and postulates a model for planning EIS and related library services. From the new extended model of information behaviour, sixteen main measures or indicators were tested on a proposed framework in developing performance measures to diagnose information behaviours and predict EIS use, satisfaction and success in problem-solving. In measuring EIS, the researcher suggested the holistic approach in assessing traditional (non-electronic) library and information services as part of information behaviours of clinicians. The study pointed to the imbalance between self-efficacy and the actual skills and knowledge of users in their searching mentality and activities and the implication for library practice. Qualitative aspects that require further research on measurement were suggested. The study has important ramifications for theory and practice for the information professional. The new extended model of information behaviour for clinicians establishes deterministic relationships that help explain why an information search is pursued actively, continuously, or not at all. Measures that have been derived from these relationships can help diagnose and predict information behaviours. The study highlights the flexibility and utility of the general model of information behaviour. Also, this is the first time that such a methodological approach has been adopted to derive EIS measures. The application of the randomized controlled study methodology in information science was proven to be feasible and yielded definitive results. The researcher proposes that further development of information behaviour model should incorporate the element of knowledge generation process in an organization.
