The EPs method is applied to investigate the ongoing phenomenon of Web communication, for the impact of emotional factors...

Investigation into the effect of wind power based embedded generators on distribution networks

Ibrahim Moh'd Ali Rida
Wind turbine-generators are usually integrated into utilities' electrical networks at distribution voltage levels, and they are commonly known as "Embedded Generators" (EGs). Recently, it has been reported that the integration of wind power-based embedded generators (WPBEGs) into distribution networks could cause maloperation of automatic voltage control (AVC) relays. Further investigation is therefore required to improve the performance of AVC relays in the presence of EGs. On the other hand, the dynamic effects of WPBEGs on...

The education of undergraduate product designers in the principles and practice of sustainable design

Kirsty Amanda Cull
There is a growing recognition that product designers have a responsibility to ensure that their designs are intrinsically sustainable and do not add to the growing pressures on the environment. Developing sustainable products requires designers to be aware of the conflicting issues and constraints that need to be taken into account as part of the design process. Finding appropriate ways to provide the essential knowledge to support designers so that they can develop sustainable products...

Changing society: pioneering women entrepreneurs in Saudi Arabia

Sosan Algahtani
The research examines the role of institutions influencing Saudi female entrepreneurs, and how they became enabled to be social agents and institutional entrepreneurs in a very traditional, family-orientated society - albeit facing pressures to change. In acknowledging the uniqueness of the social-cultural context in Saudi Arabia, this study adopts a qualitative design. Specifically, purposive and snowball sampling techniques were implemented to gather primary qualitative data. The data draw on 31 interviews with female entrepreneurs residing...

An environmental-psychological study of sustainable housing: a transactional approach

Tony Craig
The main aim of this thesis is to utilise the transactional approach from environmental psychology for the study of sustainable housing. The interdisciplinary field of environmental psychology has recognised for some time the importance of considering human behaviour not only in terms of personal psychological processes, but also in terms of the broader social and physical context in which behaviour occurs. This need to consider phenomena at different levels of analysis sits comfortably with the...

The search for missing pieces: a grounded theory of adult adoptees' experiences of searching and re-engaging with birth families

Clare Swan
The lived experience of adult adoptees in searching and re-engaging with birth families is an under-researched area, and receives limited focus in social work practice and policy. The aim of this study is to explore both the experience and the impact of searching and re-engaging with birth families on the emotional and psychological wellbeing of adult adoptees. The study adopted a constructivist grounded theory methodology, drawing on the principles of phenomenology and symbolic interactionism. The...

Dynamic relationship between oil price and macroeconomic variables: evidence from oil exporting and oil importing countries in Africa

Chinedu Nnenna Okoro
This study examines the asymmetric long-run and short-run relationship between oil price and key macroeconomic variables, within the context of net oil-exporting and importing countries in Africa. Using quarterly data ranging from 1996(Q1) to 2016(Q4), panel ARDL estimation is carried out to analyse how asymmetric changes in oil price affect macroeconomic activities in African countries and whether the effects are similar or different in oil importing and exporting African countries. The results show significant positive...

An exploration of the contribution of the arts to local economies in terms of human and social capital

Shauna Narine
Although research exists about the positive impacts of the arts on well-being and society, public funding towards this sector in the UK has decreased significantly over the past decade. Researchers suggest a demonstration of how the arts impact local economies is necessary to justify their funding. This thesis provides a demonstration that, in addition to being good in themselves, the arts have a positive effect on the economy. It utilised Critical Discourse Analysis (CDA) to...

An investigation of contemporary public building design with particular reference to disabled peoples' design needs and designer awareness

Joanne Milner
The hypothesis presented in this study is to test the theory that designers do not give adequate consideration to the needs of people with disabilities and that they perceive of people with disabilities as a separate minority who require 'special' provision. Within this context it is suggested that building designers would be more able to serve the needs of people with disabilities if building design education incorporated a more holistic and user-responsive syllabus. The research...

An exploration of the use of theory and visualisation in behaviour change interventions to help healthcare staff prevent and control healthcare-associated infections

Kostas Tsattalios
Changing healthcare staff's behaviours is of paramount importance in improving infection prevention and control (IPC), and decreasing healthcare-associated infections (HAIs). Thus many supportive interventions have been developed in pertinent areas, such as hand hygiene (HH). The concepts of theory and visualisation in behaviour change research are well described and embraced across the social sciences as they provide rigorous and innovative interventional solutions. However, the use of each of these concepts within interventions in IPC and...

An appraisal of wind energy conversion systems for agricultural enterprises

Susan Macmillan
A detailed wind prediction model is developed, which predicts wind regimes and energy outputs from wind turbine generators at locations that are remote from sites where long-term wind data is available. The model accounts for the local, directional influences on the wind flow of topography and surface characteristics. The model for the validation runs performs well and predicts energy outputs over several months to generally within 7% of the actual energy outputs. Experience is described...

Computational fluid dynamics modelling of multi-phase flow transition in presence of solid particles

David Alaita
Multi-phase flow is the type of flow common in the oil and gas industry, as oil reservoirs contain mixtures of oil, gas and water with sand particles from sandstone reservoirs. Accurate design of oil and gas production equipment greatly depends on detailed understanding of this flow phenomena. Previously, multi-phase studies relied upon empirical correlation and mechanistic equations developed from experimental data, but these approaches have limitations because of limited experimental data and underlying simplified assumptions....

The utility of mathematical fitness-fatigue models for assisting with the planning of physical training for sport: from in silico experiments employing synthetic data, lower-bound operational conditions and model estimation, to the development of software resources for future research

Benedict H. Stephens Hemingway
The greatest potential application of mathematical models in sport science is to predict future performance of individual athletes in response to training, with sufficient accuracy to assist with planning of training programs and short tapering periods. The most widely known and investigated set of mathematical models include the fitness-fatigue models (FFMs). However, despite over 45 years of FFM study, problems remaining within the research base and gaps in existing knowledge have limited interpretation of prior...

The importance of the protection of micro enterprises in B2B international commercial contracts

Oyefunke Adetoba
This thesis examines the growing disparity in the application of the doctrine of freedom of contract in international commercial contracts, because of the need to protect perceived weaker parties. Using the qualitative doctrinal legal research and adopting an interdisciplinary approach to enquiry, it weighs the current protection available to micro enterprises against the vast protection given to consumers in international commercial contracts, under the relevant EU Directives and Regulations, and under English law (pre- and...

The relationship between the social licence and law in the context of the Scottish fracking debate: a textual, thematic and comparative analysis of environmental and planning law governing onshore oil and gas authorisations in Scotland

Andrew Jones
The Governments of the constituent parts of the UK have, in recent years, considered promoting the exploitation of UK shale formations via fracking in order to recover oil and gas. In all jurisdictions, this has been met with opposition groups citing environmental risks. Various groups have called for either an outright ban on this process or for regulatory reform to address specific concerns. In Scotland, this led to an impasse, with the Scottish Government eventually...

The development of an electrochemical sensing device for controlled drugs

Stuart Waddell
Forensic chemists can be faced with a wide array of substances to test when attending clandestine drug manufacture crime scenes. Whilst many techniques exist at their disposal - such as chemical colour test reagents and immunoassays - these methods are at best semi-quantitative and often subject to false positives. Electrochemical methods of detection offer a potential solution to this problem, as the equipment is portable, cheap and robust. The analysis is quantitative and, if the...
