▼ Many chemotherapy drugs act by inducing DNA damage leading to cell death, and the platinum analogue class of anticancer drugs are the most commonly used DNA damaging chemotherapeutic drugs. Despite extensive analysis of platinum-DNA interactions, particularly characterising the individual adducts and their effects on DNA replication, transcription and cell survival, measurement of these adducts in cells with higher sensitivity and precision is necessary. Previous work studying platinum-DNA adduct formation has been performed using DNA damage assays such as immuno-slot-blots to detect whole genome DNA damage, or with combinations of chromatography and mass spectrometry to characterise each adduct individually. The ability to measure platinum-induced DNA damage genome-wide with high resolution in human cells could have profound implications for basic mechanistic research, as well as clinical translational research and treatment stratification, by providing a tool with the potential for predicting clinical response to these agents. The achievement of this PhD was developing an assay to measure platinuminduced DNA damage induction at high resolution, density and precision within the genome of human cells. This was achieved using DNA immunoprecipitation coupled with analysis using DNA microarrays, allowing measurements of platinum-induced DNA damage to be made at high resolution throughout the human genome for the first time. This assay was initially developed to measure cisplatin and oxaliplatin induced DNA damage in the genome of the yeast model organism Saccharomyces cerevisiae and experimental profiles of cisplatin and oxaliplatin-induced DNA damage were validated by demonstrating close correlation with mathematically generated predicted profiles for platinum-induced DNA damage. The assay was then applied and validated to measure cisplatin, oxaliplatin and ultraviolet-induced CPD formation in human fibroblast cells, and again, experimental profiles of cisplatin and oxaliplatin-induced DNA damage and UV-induced CPD formation were shown to correlate well with predicted profiles of DNA damage. Novel comparative analytical approaches for studying microarray data from these genome-wide DNA damage datasets are demonstrated and further validation of the assay is provided by demonstrating the contrast between platinum-induced DNA damage and UV-induced CPD formation genome-wide and in the context of repeat sequences of DNA. Finally, cisplatin and oxaliplatin-induced histone H3 acetylation changes are examined and histone H3 K14 acetylation is demonstrated to be a prominent histone modification following exposure to platinum analogues. Novel analysis is performed to investigate the influence of chromatin on platinum adduct formation, and greater platinum-induced DNA damage is demonstrated in DNA samples treated in vitro compared with DNA samples taken from cells treated in culture. Comparisons were also performed between histone H3 acetylation in yeast cells following exposure to cisplatin or UV irradiation and this comparison…

▼ Saprotrophic fungi are the main agents of primary decomposition and nutrient cycling in woodland ecosystems. Powerful enzymatic capabilities enable then to break down the most recalcitrant components of wood and leaf litter, such as lignin and cellulose. Nutrients are retained by dynamic networks of mycelium, which are vulnerable to grazing by soil invertebrates. The studies reported in this thesis employed laboratory microcosm, mesocosm and field manipulations to further mechanistic understanding of climate change effects on basidiomycete fungal-dominated woodland decomposer community dynamics and ecosystem processes. Increased mycelial growth at elevated temperature can be prevented by collembola grazing in soil microcosms. The strength of this top-down effect varied with fungal palatability, which had a bottom-up effect on collembola populations and their responses to warming. A mesocosm multispecies collembola population was more strongly regulated by the bottom-up effect of inoculation with cord-forming fungi than climate change (warming, in combination with soil wetting or drying). Collembola can graze fungal cords, but thickness and chemical defences make them less palatable than soil microfungi, which are outcompeted by basidiomycete mycelia. In the absence of fungal biomass limitation by collembola, abiotic conditions regulated microbial community functioning. Warming stimulated fungal-mediated wood decomposition, particularly in drier soils. Moisture was the most important determinant of enzyme activity and displayed an interaction with temperature analogous to that for wood decay. Macro-invertebrates, such as woodlice, are better able to exploit nutritious, but thick and defensive, fungal cords. The consequences of macro-invertebrate grazing for fungal-dominated microbial community function were tested in a field manipulation of woodlouse (Oniscus asellus, Isopoda) population densities, predicted to increase due to climate warming. This provides the first evidence for bottom-up effects of fungal palatability on woodlouse populations. Body lipid analysis revealed fungi as a major component of the generalist woodlouse diet. Despite low population densities at the site, altered O. asellus abundance influenced aspects of microbial community functioning. The importance of biotic effects on decomposition may be more heterogeneous than abiotic influences, depending on microbial community dominance and the abundance of key macro-invertebrate taxa.

▼ Advances in data gathering have led to the creation of very large collections across different fields like industrial site sensor measurements or the account statuses of a financial institution's clients. The ability to learn classification rules, rules that associate specific attribute values with a specific class label, from this data is important and useful in a range of applications. While many methods to facilitate this task have been proposed, existing work has focused on categorical datasets and very few solutions that can derive classification rules of associated continuous ranges (numerical intervals) have been developed. Furthermore, these solutions have solely relied in classification performance as a means of evaluation and therefore focus on the mining of mutually exclusive classification rules and the correct prediction of the most dominant class values. As a result existing solutions demonstrate only limited utility when applied for data characterization tasks. This thesis proposes a method that derives range-based classification rules from numerical data inspired by classification association rule mining. The presented method searches for associated numerical ranges that have a class value as their consequent and meet a set of user defined criteria. A new interestingness measure is proposed for evaluating the density of range-based rules and four heuristic based approaches are presented for targeting different sets of rules. Extensive experiments demonstrate the effectiveness of the new algorithm for classification tasks when compared to existing solutions and its utility as a solution for data characterization.

▼ The freshwater pearl mussel (FPM) is an iconic bivalve mollusc whose presence in rivers is assumed to indicate a healthy, bio-diverse ecosystem, capable of providing a range of goods and services. However, excessive sedimentation has been shown consistently to have detrimental effects on FPM, at both the juvenile and adult life stages. As a major source of diffuse river pollution, previous studies have shown erosion rates rising with increasing precipitation, suggesting also increased risk under wetter, future climates. So far, however, most erosion studies have been at the small plot scale and hence it is not possible to make predictions at the catchment scale where risk assessments for FPM are most relevant. Furthermore, little research has focussed on how work to remediate sediment delivery might affect public appreciation of rivers as highly valued landscape features. This research focussed on three typical FPM rivers in the UK: the Ehen catchment in Northern England; the Conwy in North Wales and the Dee in East Scotland and asked 1) How will climate change predictions for the period 2010 – 2039 affect soil erosion at the catchment scale? 2) What factors influence public attitudes towards rivers, the FPM, and mitigation measures to control sediment movement? and 3) Can habitat management for FPMs take into account climate-driven environmental change and social values when constructing conservation goals? In respect of the first aim, the Pan-European Soil Erosion Risk assessment model, PESERA, showed that whilst soil erosion rates increased with rising precipitation, land cover was a more dominant driver of erosion rates over the period studied (2010-2039). Despite being flatter, arable land had higher erosion rates than those from forested portions of each catchment, which were in regions of steeper topography. Secondly, based on a mixture of qualitative focus groups and quantitative surveys, the majority of people had positive attitudes toward rivers, both in a general and local sense. The FPM was not a well-known aquatic species but information about possible human or ecological beneficiaries of mitigation to control sediment delivery into rivers did not affect how acceptable these measures were perceived to be. Factors increasing acceptability of mitigation measures included natural looking scenes that were accessible. In contrast, concerns about impacts on agriculture and food production led to lower levels of acceptability. Finally, this research highlighted crossovers between FPM habitat needs and ideal river scenes from a public perspective and concluded that social values of riverscapes can be included in habitat management plans for the FPM, without compromising conservation goals. A case study exemplifying the methodology used to do this, using the Dee catchment, Scotland and future scenarios from the National Ecosystem Assessment showed that conservation measures in aid of the FPM can accommodate different land management priorities and societal needs. As one of the first studies to assess interactions…

▼ The concept of organizational culture has been an enduring managerial fad, with more recent studies highlighting the benefits of fun workplace cultures. This thesis presents the findings from a longitudinal ethnographic study of the I.T organization, WebCo; an organization that emphasizes its unitary culture as the central driver of its success. The author conducted two separate periods of ethnographic research and interviews in order to understand the managerial attempts at sustaining WebCo’s strong organizational culture that exhibited many elements of fun. The dynamics between employees and the on-going managerial attempts at sustaining normative forms of control are used to explore the manageability of organizational culture debate. Furthermore, this thesis comprehensively analyzes the interrelationship between organizational culture and structure. Through the longitudinal research design, this study explores the use of a range of introduced structural practices in order to sustain the organizational culture through a period of rapid growth in organizational members. The results of this study contradict any notion of unitary culture and indicate major fractures between different sub-cultures located within WebCo. The highlighted complexity of social relationships critiques the dominance of functional literature in the area of organizational culture and attention is drawn to the knowledgeable employees and their agentic power in circumventing normative forms of control. A further finding of this study is that the management of culture can be effective, but only when supported with other aspects of ‘good work’. The study concludes therefore, by noting how organizational culture can be managed, yet not as a distinct and separate activity.

▼ Post structuralist research is increasingly influencing environmental knowledge – feminist/post-colonial authors have led the path for incorporating subjective and lived experiences of human-nature interactions into environmental discourses. In India's southern context, however, environmental literature, policy and governance are still dominated by structuralist discourses; hence wider environmental knowledge and governance remain detached from everyday life. Using a theoretical framework of "sustainable development" and "ecological citizenship", this PhD aims to rectify this literature gap through a qualitative analysis of agri-tourism in Maharashtra. Within peri-urban Mumbai and Pune, industrialization and urbanization are transforming the agrarian landscape. Although urbanization is displacing farmers from cultivation, it is also creating new opportunities through markets, education, employment and connectivity. These contribute to agriculture's transformation into serving multiple roles beyond food production – towards higher levels of multifunctionality. Agri-tourism is a form of agricultural multifunctionality. Farm owners provide urban visitors with accommodation, activities and entertainment on their privately owned farms. As a rural service, agri-tourism provides urban visitors a flavour of rural life and culture through recreation, farming activities and rural products. While revenue and jobs are created, there are also new opportunities for rural and urban interactions and environmental learning. Even though the news-media often portrays agri-tourism as "sustainable" and a low impact alternative to mainstream tourism, these claims have not been tested on the ground. Through fieldwork in three agri-tourism farms, this research unpacks how sustainability is interpreted in agri-tourism. It analyses how agri-tourism stakeholders (farm owners, urban visitors, employees and villagers) perceive notions of environmental responsibility and entitlements in the farm. Using narratives from over eighty semi-structured interviews, the analysis draws wider connections with neo-liberal policies in India. The study concludes that the most significant factor in shaping people's attitudes and values towards the environment is how they perceive "rurality" and "urbanization" in everyday life.

▼ As electronics become more and more miniaturised, there is much interest in increasing knowledge about the electronic and transport properties of nano-systems. In particular, there has been some focus on understanding the physics of nanowires with prescribed properties. Two different groups of systems have been considered that of 1D organic molecular nanowires and 2D interconnects based on graphene. In order to develop a deeper insight of the factors that determine the electronic structure and consequently the electrical transport properties, it is desirable to carry out computer simulation studies of these systems. The work reported in this thesis has focused on studying the porphyrin and DNA molecules as well as investigating the consequences of engineered 2D graphene interconnect. The latter class of systems has included graphene nanoribbons (GNRs), graphene sheets with grain boundaries (GGBs) and graphene nanomeshes (GNMs). The methodology was to use self-consistent extended Hückel theory (SC-EHT) and density functional theory (DFT) in combination with non-equilibrium Green functions (NEGFs) formalism to investigate the electronic and transport properties of these systems. The SC-EHT calculations were performed using an in-house developed C++ code named EHTransport. While the SIESTA package was employed for the DFT. It was found that the SC-EHT approach produced comparable results with that obtained by DFT. This supports the idea that the semi-empirical methods can be as valid as ab-initio approaches. The findings demonstrated that porphyrin, DNA, and graphene based systems are very promising candidates to incorporate in future electronics.

▼ The studies comprising this thesis were conducted to further understand how structural changes to the corneal extracellular matrix can affect the cornea’s unique properties, with the ultimate goal of improving novel treatments and their outcomes. Following refractive surgery, changes in matrix structure can cause loss of structural integrity and transparency, which may adversely affect the surgical outcome. The first objective was to define what governs corneal shape and ultrastructural organisation by analysing the abnormal post-hatch corneal collagen arrangement in an avian model (beg). Structural information was also obtained post-in vivo microwave keratoplasty to assess the treatment as a suitable alternative to more invasive correction procedures. In addition, modifying the resident cell type as a means of improving post-treatment wound healing following LASIK was also investigated using corneal stromal stem cells. Finally, the efficiency of transepithelial riboflavin/UVA collagen cross-linking in terms of riboflavin uptake and post-treatment corneal stiffness, was evaluated. X-ray scattering studies revealed that corneal flattening in beg chickens is related to biomechanical changes brought about by an alteration in collagen arrangement at the corneal periphery. This highlights the importance of the limbal fibril annulus in corneal shape preservation. X-ray studies also revealed that microwave keratoplasty may impact on peripheral vision by introducing spatial disruption of stromal collagen, resulting in localised corneal opacity in the treatment area. Loss of fibrillar structure and order could also have further implications for corneal biomechanics and shape. The application of human corneal stromal stem cells under LASIK-like flaps was revealed to be a promising approach for increasing flap adherence strength whilst maintaining corneal clarity. Introducing these cells in the early stages of flap-healing appears to improve the repair process, conceivably through an embryonic-like mechanism. Lastly, stress-strain and riboflavin uptake results for transepithelial riboflavin delivery during corneal cross-linking were encouraging, however refinements to the testing procedure are required to fully assess the treatment efficacy. Collectively these findings accentuate the importance of the precise stromal collagen fibril arrangement and composition for maintaining corneal transparency, shape and general functionality. All these factors must be taken into consideration when implementing novel correction procedures or modifying existing treatments for corneal defects.

▼ This thesis explores whether ‘business model innovation’ could hold the key to advancing the ultra-low and zero carbon vehicle industry in the United Kingdom. This thesis presents a critical comparison of two case studies drawn from qualitative research conducted with a broad cross-section of UK vehicle manufacturers (VMs) that are interested in introducing zero carbon vehicles to the marketplace. The two cases, looking at large established producers of vehicles with trans-national presence (herein termed TNC/MNC VMs) and smaller producers (herein termed SME VMs). The two cases consist of a number of grouped embedded cases focusing on the activities of vehicle producers that are in the process of introducing Ultra-Low Emission Vehicles (ULEVs) to the UK marketplace. These cases are constructed and informed by both primary research, semi-structured interviews conducted with representatives of these VMs, secondary analysis of interviews conducted with VM representatives and industry commentators and documentary analysis of contemporary sources and industry commentary. The thesis is framed within a broader academic debate regarding the nature of achieving socio-technical transitions. Within this frame of reference, particular attention is paid to the role of large incumbents vs. new start-up insurgents in bringing innovative technologies to the marketplace; innovative technologies being seen as a key component of a transition to a more sustainable world. In comparing the business models of large, well-established vehicle manufacturers, with smaller, newer, SME providers the ontology of Business Models developed by Osterwalder & Pigneur (2002) is used to interrogate, analyse and make comparisons between the business models of a range of companies that are very dissimilar in nature. Context is crucial to understanding the detail of case studies; as such, the thesis is also informed by the perspectives, gained through interviews, of a number of industry commentators, representatives of government organisations and automotive trade bodies. ~ xxviii ~ This thesis set out to explore a number of research themes and the contributions to knowledge that this thesis has made are: Establishing a theoretical linkage between Geels (2006) multi-level perspective of transitions literature and Osterwalder & Pigneur’s (2002) business model ontology. By bringing these two powerful tools together, it is proposed that a complimentary analysis of the business model on the micro level, embedded within an overall socio-technical transition at the macro level can be made. Furthermore, through an empirical analysis of business models in the car industry, a range of business model components, new directions for business models and “complementary” ancillary business models that support the introduction of ULEVs has been identified. Disappointingly, whilst some observation are made about the early stages of transitions, the slow uptake of ULEVs in the marketplace has shown that the incumbent regime is still reistant to transition – and no concrete…

▼ Environmental restoration is emerging as a major driver in the repair and reversal of some of the world’s most severely degraded landscape systems, with growing interest in the status and composition of restoration efforts. Although much has already been written about the theory and practice of environmental restoration, both positive and negative, hitherto the literature has tended to overlook the complexity bound up in defining restoration discourses, and perhaps more importantly, the physical, material consequences instilled through such human choice. The mutability of discourses of environmental restoration means that it can be moulded and (re-)shaped by different actors and contexts, with different values and meanings attached to ‘nature’. There exist multiple and contested natures of environmental restoration - nature(s) both in the sense o f the properties of restoration, and also that which is restored to a site. In this doctoral thesis, I demonstrate how discourses of environmental restoration are defined and interpreted, which discourses (if any) appear to dominate, and how these are mobilised to produce ‘restored nature’. Attention is also awarded to the environmental implications incurred when such discourses are played out on the ground. The research is grounded empirically through reference to the case studies o f the Eden Project (Cornwall, UK), the National Forest Company (Derbyshire, UK), and the Walden Woods Project (Lincoln, MA) and their adoption of restoration practices. Analysing the processes and practices of environmental restoration within a framework of social nature and cultural landscapes serves to destabilise the dualism distancing nature from society - a preserve of environmental ethics and philosophy - for such synergy not only highlights how ideas of (restored) nature are socially constructed, but also addresses the material production of nature, reinforcing the interactions between natural and societal actors.

▼ Background: A link between youth homelessness and mental illness is recognised (Bines, 1994; Craig & Hodson, 1998; Kamieniecki, 2001; Whitbeck, Johnson, Hoyt, Cauce, 2004). However, very little empirically robust research has examined the role mental health plays in the lives of young homeless people, particularly in the United Kingdom. In the UK, approximately 80,000 young people are known to experience homelessness each year. The actual figure is likely to be far larger as it does not take into account those young people who are ‘hidden homeless’ (DePaul UK, 2013). Young people with experiences of homelessness represent a highly vulnerable group in terms of their mental health (Hodgson, Shelton, van den Bree & Los, 2013). This thesis aimed to explore the relationship between psychopathology and youth homelessness and presents the findings of a prospective longitudinal study comprising of three interview stages over the course of two years. The design aims to address the gaps in our knowledge about these two phenomena. The thesis begins by providing an introduction to the area of youth homelessness in the UK (Chapter 1). The relationship between mental illness and homelessness is explored by drawing on a number of psychological theories including family systems, attachment, diathesis stress and the social support stress buffering hypothesis. This is followed by a systematic literature review examining the prevalence of mental health issues within this population and exploring the link between the two phenomena (Chapter 2). The review reveals high rates of psychopathology among young homeless people and identifies a possible reciprocal relationship between homelessness and mental illness. Chapter 3 provides a description of the research method and questionnaires. The longitudinal design used in this project involved three waves of data collection using a pack of questionnaires that explored a range of housing situations, family background, maltreatment, 2 criminality, self-control, loneliness and self-mastery. The interviews also included a full neuropsychiatric assessment in order to assess presence or absence of mental illness. In Chapter 4 a detailed description of the 121 participants recruited for the study revealed a sample representative of the youth homeless population as a whole. The sample had high levels of mental health problems (88%) and had a number of other areas of vulnerability including high rates of comorbidity, past abuse experiences, heavy use of drugs and alcohol, problematic family relationships and premature exits from education. Chapter 5 involved the analysis of the relationship between current disorder and future access to health and mental health services. The results revealed that while young homeless people had a particularly high rate of disorder they also had relatively low levels of access to appropriate services at follow up. However, access to emergency medical care was high. Some forms of disorder, such as depression, were particularly predictive of future health care use whereas…

▼ The purpose of this thesis is to critically highlight the development of solar absorption refrigeration technologies through time. The factors that have prompted the urgent need to reconsider this area of engineering will also be analyzed in depth. The relevant research in the area of solar absorption to date will be shown with specific emphasis on its contribution to industrial and domestic cooling systems. The Middle East may be awash with oil in the present circumstances with 48% of the known oil reserves in the world but challenges exist owing to fossil fuel being a finite resource and its exploitation fraught with environmental problems. Therefore developing solar cooling systems appears to be an essential and inevitable requisite for harnessing solar energy in order to make a lasting contribution to the development of the region, as well as the world Targeting the coefficient of performance (COP) of the solar absorption refrigeration systems was considered to be the fundamental part of this research. By investigating the absorber chamber in an absorption refrigeration system, it was found that enhancing the quality of the spray of the absorber fluid could raise the COP. Using a Phase Doppler Anemometry (PDA), a detailed analysis of the spray characteristics was achievable; this helped in targeting parameters which will have influence on the spray characteristics. These include the nozzle geometry, for instance, the size of orifice, as well as the internal forces of the liquid such as viscosity and surface tension. Operating parameters were also considered to influence the spray quality. The main operating parameter is to create a partial vacuum to simulate the absorber chamber working condition. Results revealed that high viscosity of the fluid and the vacuum had negative effects towards spray quality. But when combining these with a surfactant such as 2-ethyl-1-hexanol, the spray quality increases in terms of droplet diameter, which in turn decreases and thereby causes an increase in the surface area to volume ratio, resulting in the enhancement of COP.

▼ This thesis is part of a journey that has encompassed a lifetime love of horses. It evolved from horses being a childhood passion, and led to working with horses together with young people with various disadvantages and difficulties in a therapeutic and educational capacity. The PhD research study followed as an attempt to articulate and share some of the experiences of ‘The Yard’, the therapeutic horsemanship (TH) programme on which this thesis is based. Through a personal belief and understanding that contact with horses could be therapeutic in a number of ways I found myself in the fortunate position to be able to incorporate TH in my work as a social worker for a foster care company. Whilst initially this was limited to young people who were in foster placements with this particular company, the TH programme expanded through interest from outside agencies to include young people referred from youth offending and other organisations. The young people who attended the TH programme, named ‘The Yard’ for the purpose of this study, were generally considered to be ‘at-risk’ within the social work and allied professions due to their circumstances and histories. Substantial research within the literature concerned with risk and resilience claims there is a high likelihood of negative life outcomes as a result of experiencing adverse childhood experiences (Masten, Best, & Garmezy, 1990; Rutter, 1985). It cannot be claimed that this thesis is completely impartial or objective; on the contrary it is a deeply personal and reflexive account of my experiences alongside seven of the young people who attended The Yard and participated in the study. I can only hope that through the many hundreds of hours of the meticulous process that has made up this practitioner-researcher ethnography, that I have provided some kind of useful contribution to the knowledge base of TH. In any case, at the very least, it has certainly been a hugely worthwhile endeavour in terms of gaining invaluable insight into my own practice, together with associated personal and professional growth.

▼ This study examines the nature of a particular type of atypical reference. In [1], it is possible to understand ‘a man who…’ as a newly introduced referent or ‘type’. But once seen in context, where the identity of this particular man has been firmly established, it becomes clear that its function is more definite than indefinite. [1] […] a man who achieved the rare feat of becoming a pivotal member of the Cameron inner circle in the space of just a few months in the summer and autumn of 2007 Expressions such as that in [1], with the structure A(n)+NOUN+RESTRICTIVE RELATIVE CLAUSE are examined in the context of British English journalistic opinion writing from four different, but related perspectives: - Readers’ interpretations: Empirical evidence from two experiments shows that readers largely do not interpret the expression as referring to a ‘type’, but rather to the previously mentioned, fully-identified entity. The results also suggest that the amount and detail of conceptual information in the relative clause plays a role in the interpretation. - Cognitive processes in referring: The expression is examined and analysed alongside cognitive models of referring and it is shown that these expressions are considered ‘accessible’ in the mind of the addressee. - Lexical cohesive ties: The meaning relation of co-extension (Hasan 1985) is exploited to explain how these expressions become functionally definite within their specific context. Cohesive semantic ties (i.e. similarity chains)between the expression and the preceding text and on-going discourse aid the transformation from formally indefinite to functionally definite. - Insights on the discourse: Insights from linguists and journalists are brought together to examine the function of these expressions. It is suggested that they have a dual function, to refer to the identified individual as well as to others with similar features. This study concludes that this atypical expression carries both definite and indefinite information and to fully capture its use and function, the entire discourse event needs to be taken into consideration.

▼ Nurses in Palestine work in a significantly challenging environment within and outside their workplaces. Mental health services in Palestine are underdeveloped and under-resourced. For example, the total number of community mental health nurses (CMHNs) in the West Bank is seventeen, clearly insufficient in a total population of approximately 3 million. This thesis is concerned with the resilience of nurses who work in community mental health workplaces in Palestine. This research explored sources of resilience and daily challenges that Palestinian CMHNs face within and outside their demanding workplaces. The up to date understanding of resilience is drawn from the social ecological perspective. Within Arabic culture, resilience has traditionally been conceptualised as a prerequisite to understanding and achieving ‘Sumud’, meaning that the individual has to be resilient in order to remain steadfast in the face of daily challenges and not to leave their place or position. An interpretive qualitative design was chosen to explore resilience and the daily challenges. Fifteen face-to-face interviews were completed with participants. Thirty-two hours of observations of the day-to-day working environment and workplace routines were conducted in two communities’ mental health centres. Written documents relating to practical job-related policies were also collected from various workplaces. Thematic analysis was used across all data sources resulting in four main themes, which describe the challenges faced by CMHNs and their sources of resilience. These themes consist of the context of unrest, societal challenges, lack of resources and organisational challenges. These sources are Sumud and Islamic cultures, supportive relationships, making use of the available resources, and personal capacity. The study concludes with a better understanding of resilience in nursing which draws on wider cultural contexts and responses. The outcome of this thesis will be used to develop the resilience of CMHNs in Palestine.

▼ The theory of cometary panspermia is tested in the wake of two reported falls in Tissint, Morocco on July 18, 2011 and in the central province of Polonnaruwa, Sri Lanka on December 29, 2012. Samples of the Tissint and Polonnaruwa stones were studied using a variety of laboratory procedures and equipment including ICP-OES, GC-MS, SEM, EDAX, CHN, FTIR, Raman Spectroscopy, XRD and Optical Spectroscopy. Results of Tissint show the presence of several 5-50μm pyrite grains rimmed by a layer of reduced organic carbon with graphitisation levels consistent with other Martian meteorites. A complex precursor carbon inventory is demonstrated with peak temperatures ~ 250 OC and elemental ratios typical of high volatility bituminous coals. A theoretical model of the ecology of arsenic on early Mars is then developed and discussed involving microbial reduction of Fe-oxides. This hypothesis is shown to be supported by SEM observations of spherical chains of pits, with morphologies distinct from abiotic alteration features but closely comparable to biologically mediated microstructures created by Fe- and S-oxidising microbes. The contribution of core-mantle grains to mid-IR emission features is then modelled using extinction and scattering efficiencies for composite spheres based on the Guttler extension of the Mie formulae. Results show that kerogen-pyrite grains closely adhere to observed 9-13μm emission characteristics observed in the Trapezium nebula. Results of studies on Polonnaruwa show a highly porous Si-K-rich, Al-depleted, amorphous melt enclosing trace (commonly <1μm) anorthoclase, albite, anorthite and quartz. Bound H2O < 0.03wt% indicates origin from hypervelocity impact. SEM analysis revealed several fossil microorganisms similar to acritarchs, hystrichospheres and diatoms. Geologic age of the stones is determined by N/C atomic ratio depletion that indicate the presence of embedded fossil remains that date back to at least ~300 Ma. Triple oxygen isotope analysis provide values of Δ17O = - 0.335 with δ17O = 8.978 ± 0.050 and δ18O = 17.816 ± 0.100 that is shown to be consistent with non-terrestrial sources. Results are seen to substantially support the theory of cometary panspermia.

▼ Attention deficit hyperactivity disorder (ADHD) is a common and impairing neurodevelopmental disorder, which frequently co-occurs with autism spectrum disorder (ASD). Both disorders are highly heritable and recent studies report a substantial degree of overlap in genetic risks for ADHD and ASD. The overall objective of this thesis is to examine the clinical co-occurrence and shared genetic susceptibility of these conditions, as well as of related developmental problems. First, the presentation of ASD traits is examined in a clinical sample of children diagnosed with ADHD. This is followed by an assessment of whether the presence of ASD traits in children with ADHD is associated with additional cognitive or developmental difficulties. Lastly, it is investigated whether common genetic risk variants which are associated with clinically-diagnosed ADHD are also associated with ADHD traits, ASD-like social-communication difficulties and neurocognitive abilities (i.e. IQ, working memory, inhibitory control and facial emotion recognition) in children from a general population sample. The results show that ASD traits split into separate, albeit correlated dimensions of social-communication difficulties and restrictive, repetitive behaviours (RRBs) in children with ADHD. They also suggest that there may be some overlap of RRBs and hyperactive-impulsive ADHD symptoms. Increasing levels of ASD traits in children with ADHD are found to index more ADHD symptoms, as well as lower cognitive abilities and a greater likelihood of developmental difficulties. Finally, the results demonstrate that common genetic risk variants relevant to ADHD diagnosis are associated with ADHD and social-communication problems as well as cognitive difficulties (lower IQ and working memory abilities) in children in the general population. This thesis extends our understanding of the clinical importance of assessing ASD in the context of ADHD. Furthermore, the findings demonstrate that common genetic risk variants for childhood ADHD are also relevant to other neurodevelopmental and cognitive outcomes in the general population.

▼ The training and skills of educational psychologists (EPs) mean that they are uniquely qualified to deliver critical incident (CI) support to educational settings. One aspect of this support may involve producing written guidelines for schools; however such guidelines have received almost no attention in the research literature. An exploratory study was undertaken, in two phases, to explore current practice in the production and use of CI guidelines. Phase 1 involved the collection and content analysis of guidelines from a random sample of educational psychology services (EPSs) in England and Wales. Phase 2 involved semi-structured interviews with professionals, predominantly EPs; transcripts were analysed using thematic analysis. In phase 1, 97% of the sample stated that their EPS offered CI support to schools and 83% stated that they had produced written guidelines to support schools. Analysis found that the most frequently occurring content covered: how to initiate support (95%); recommended actions for CI preparation (68%) and CI response (95%); website addresses (68%) and booklists (50%); psycho-education about grief and trauma (64%) and examples of scripts and templates (55%). Recommendations and information were largely consistent with evidence in the academic literature. Interviewees described the benefits of written guidelines but maintained personal contact was an essential part of CI intervention. The role of guidelines, their limitations and implications for EP practice are discussed.

▼ The introductory chapter provides a brief exploration of the history of childhood, and childhood representations, in Western popular thinking over the last 500 years. It also provides a brief discussion of the implications of these representations on policy, the study of children, and adult social cognition. In Chapter 2, two experiments explore the potential effects of including children in representations of outgroups on attitudes towards the outgroup, with inconclusive findings. In Chapter 3, three experiments explore the effects of priming the category of children on impressions of a novel ambiguous target (the Donald paradigm). Methodological issues and inconsistent findings mar the interpretation of effects, but an improved set of category labels for future studies of child category priming are considered in the general discussion. In Chapter 4 I take a step back and systematically explore the ways in which different childhood age groups (babies, toddlers, children, and teenagers) are represented. The first stage of data collection determined the typical age boundaries identified for children and the labels by which we delineate these different age groups. The next stage identified the emotions, beliefs, and behaviours relevant to attitudes to these groups in an open-ended listing exercise. There were differences in the content and endorsement of attitude components towards the age groups, with broadly more negative components towards older child groups than younger ones. In addition, there were fewer nurturing related components but more reparative behaviours as the age of the child increased. Chapter 5 built on these findings by developing the Child Attitude Component Scale (CACS) and testing the convergent and discriminant validity of this scale. Scores on the CACS were related but distinct from scores on measures about beliefs about humanity in general, such as the Humanity Esteem Scale and Polarity Scale. The CACS was also distinct from individual differences in emotional regulation and appraisal, self-esteem, social desirability responding and beliefs about social hierarchy. Potential spheres for testing the CACS as a predictive tool in situations concerning children are discussed alongside limitations and future directions in Chapter 6.

▼ The aim of this PhD project is to develop a fuzzy knowledge-based approach in support of risk analysis in the Customs domain. Focusing upon risk management and risk analysis in the Customs domain, this thesis explores the relationship of risk with uncertainty, fuzziness, vagueness, and imprecise knowledge and it analyses state of the art detection techniques for fraud and risk. Special focus is given to fuzzy logic, ontological engineering, and semantic modelling considering aspects such as the importance of human knowledge and semantic knowledge in the context of risk analysis for the Customs domain. An approach is presented combining the fuzzy modelling and reasoning with semantic modelling and ontologies. Fuzzy modelling and reasoning is explored in the context of risk analysis and detection in order to examine approximate human reasoning based on human knowledge. Ontologies and semantic modelling are explored as an approach to represent domain knowledge and concepts. The purpose is to enable easier communication and understanding as well as interoperability. Risk management is broader, multi-dimensional process involving a number of task, activities, and practises. The presented approach is focused on examining the analysis and detection of the risk, based on the outputs of the risk management process with the use of ontologies and fuzzy rule-based reasoning. An ontological architecture is developed in the context of the presented approach. It is considered that such architecture is possible to enable modularity, maintainability, re-usability, and extensibility and can also be extended or integrated with other ontologies. In addition, examples are discussed to illustrate representation of concepts at various levels (generic or specific) and the modelling of various semantics. Furthermore, fuzzy modelling and reasoning are investigated. This investigation consists of literature research and the use of a generic research prototype (examination of Mamdani and Sugeno model types). From theoretical research, fuzzy logic enables the expression of human knowledge with linguistic terms and it could simulate human reasoning in the context of risk analysis and detection. In addition, Hierarchical Fuzzy Systems (HFS) or Hybrid Hierarchical Fuzzy Controllers (HHFC) approaches can be used to manage complexity especially for complex domains. Linguistic fuzzy modelling (LFM) is an aspect that should be considered during fuzzy modelling. From the generic research prototype, fuzzy modelling with the use of ontologies is demonstrated together with their integration in the context of fuzzy rule-based reasoning. It is also considered that Mamdani type of fuzzy models is easier to express human knowledge since the output can be expressed with linguistic terms. However, Sugeno type of fuzzy model could be used from adaptive techniques for optimisation purposes.

▼ Viral respiratory infection exacerbates asthma symptoms in almost all patients with allergic asthma. Asthma symptoms in viral associated asthma exacerbation are often severe and require urgent care as well as hospitalisation. Corticosteroids are the mainstay treatment for asthma. However, they are less effective in treating virus associated asthma exacerbation. The main aim of the thesis is to determine the role of virus infection in airway allergic inflammation and then define the effects of corticosteroids in virus associated exacerbations of airway allergic inflammation. Mice sensitised and challenged with ovalbumin demonstrated most of the main features of asthma including lung cellular inflammation with eosinophilia, early phase asthmatic responses (EAR), late phase asthmatic responses (LAR), and airway hyperresponsiveness (AHR) to methacholine provocations. Treatment with either systemic (dexamethasone: DEX) or inhaled (fluticasone propionate: FP) corticosteroids in the murine ovalbumin allergic airways inflammation model attenuated inflammatory cells influx and eosinophilia, LAR, and the AHR. Influenza A (H1N1/PR8) is the most infective to mice compared to human parainfluenza virus type 3 (HPIV3), and a synthetic dsRNA, poly (I:C). Influenza infection in mice caused a significant increase of inflammatory cell influx in the airways with marked neutrophilia, and AHR. Ovalbumin challenge in the acute course of influenza infection on a murine model of allergic airways inflammation exacerbated the inflammatory cells influx, LAR, and AHR. Treatment with either DEX or FP attenuated the airway cellular inflammation, LAR, but not the AHR. Mice only infected with influenza were resistant to the corticosteroids (DEX and FP) treatment. DEX but not FP showed antiviral activity against HPIV3 and influenza A in vitro. These data suggest that influenza infection in a murine model of allergic airways inflammation exacerbates the inflammation and alters the sensitivity toward corticosteroids. It is also suggested that some elements in the influenza associated exacerbation of murine model of allergic airways inflammation are refractory or not regulated by corticosteroid treatment.

▼ Despite many years work on the technology of pottery production by archaeologists it is perhaps surprising that the origins of the potter’s wheel in Egypt have yet to be determined. This present project seeks to rectify this situation by determining when the potter’s wheel was introduced to Egypt, establishing in what contexts wheel-made pottery occurs, and considering the reasons why the Egyptians introduced the wheel when a well-established handmade pottery industry already existed. The potter’s wheel is often thought to have originated in Mesopotamia in the 4th millennium B.C. and subsequently its use spread to the Levant and Egypt, but little analysis has been undertaken as to why this occurred, or how its use came to be so widespread. Through a thorough analysis of all available sources, such as manufacturing marks on pottery, provenance potter’s wheels and depictions of potters in art and texts this thesis will assess the evidence for the introduction of the potter’s wheel. Through examining manufacturing marks on pottery and determining characteristics of wheel made marks by comparing them to experimental examples it is hoped a more complete view of when and in what manner the Egyptians were manufacturing their pottery vessels on the wheel will be gained. The potter’s wheel is arguably the most significant machine introduced into Egypt during the Old Kingdom, second only perhaps to the lever. This thesis concludes that the potter’s wheel was introduced to Egypt from the Levant during the reign of Pharoh Sneferu in the 4th dynasty (c.2600 B.C.). Sneferu or a member of his court sponsored their potters to use the elite-stone basalt potter’s wheel in and entirely new way, to throw pottery. The impact of this innovation would not just have affected the Egyptian potters themselves learning a new skill but also signalled the beginnings of a more complex and technologically advanced society.

▼ Volunteer tourism is a burgeoning industry, and is similarly expanding as a field of academic interest. However, much of the extant literature on this phenomenon is concerned with the motivations of volunteer tourists and their interactions with indigenous and local populations or, in the field of environmental conservationism, impacts upon local environments. There are few thick, qualitative studies of the environments created by the phenomenon within this literature, and even fewer which engage rigorously with sociological theory. Drawing on ethnographic immersion in a small community of volunteer sea-turtle conservationists in Greece, this thesis explores the types of work volunteers perform within these environments, and frames these experiences in relation to broader sociological perspectives on work, employment, and leisure. The concept of flourishing is mobilised to understand the specific types of satisfaction which the participants exhibit and report during their time volunteering. This investigation combines fieldwork and qualitative interviews to develop an empirical understanding of the everyday life of volunteering and how the participants’ experiences and accounts contrast to but are also framed by dominant discourses such as personal growth, employability, and instrumentalism found in advanced neo-liberal capitalism. The ‘thickness’ of the data, providing detailed insights into the lived experiences of volunteers through the immersive ethnographic method, allows for the social complexity of the volunteer experience to be studied. It proposes that whilst volunteer tourists employ discourses of employability and self-improvement when asked why they volunteer, the actual experiences of volunteering provide less tangible rewards, such as sensual interactions with the natural environment and human relationships reinforced by the proximity of the volunteers’ living quarters and values. This research both contributes to a growing literature on the phenomenon of volunteer tourism and adds empirical weight to an established debate concerning the relationship of Marxism to environmentalism. Using the concept of species-being in relation to the teleology of both Marxist and Aristotelian theory, it is argued that conservation work can allow individuals to flourish – in an environment in which work and leisure are more hybridised than oppositional – and for a protected species, the sea turtle, to achieve its telos.

▼ This thesis details the necessary evolutions to Cardiff University's HF measurement system and current CAD model implementation to allow for input second harmonic and mixing models to be measured, generated, and simulated. A coherent carrier distribution system was built to allow four Agilent PSGs to be trigger linked, thus enabling for the first time three harmonic active source- and load-pull measurements at X-band. Outdated CAD implementations of the Cardiff Model were made dynamic with the use of ADS' AEL. The move to a program controlled schematic population for the model allows for any type of model to be generated and input into ADS for simulation. The investigations into isolated input second harmonic models have yielded an optimal formulation augmentation that describes a quadratic magnitude and phase dependency. Furthermore, augmentations to the model formulation have to comprise of a model coefficient and its complex conjugate in order to maintain real port DC components. Any additional terms that describe higher than a cubic phase dependency are not recommended as average model accuracy plateaus, at 0.89%, from the quartic terms onwards. Further model investigations into input and output harmonic mixing of coefficients has been detailed and shows that model coefficient mixing achieves better model accuracy, however, coefficient filtering is suggested to minimize model file sizes. Finally, exercising the modelling process from measurement to design, a generated source- and load-pull mixing model was used to simulate an extrinsic input second harmonic short circuit, an intrinsic input second harmonic short circuit, and input second harmonic impedance that half-rectified the input voltage waveform with Class-B output impedances. The tests were set up to see the impact of input second harmonic tuning on drain efficiency. Efficiencies of 77.31%, 78.72%, and 73.35% were observed for the respective cases, which are approximately a 10% efficiency improvement from measurements with no input second harmonic tuning. These results indicate that to obtain performances at X-band close to theory or comparable to performance at lower frequencies input waveform engineering is required.

▼ The selective oxidation of lower alkane components of natural gas, such as ethane, to partial oxygenates remains a major challenge for both industry and academia. At present 60% of industry’s 7.8 Mt annual acetic acid demand is met through the carbonylation of methane, the operation of which is highly energy intensive, leads to formation of corrosive iodide by-products and requires high pressures of CO. Meanwhile ethene, a feedstock of great industrial importance, is produced via steam cracking of alkanes such as ethane, a process which is typically operated at > 800 °C and accounts for ca. 40% of the petrochemical industry’s annual energy consumption. The development of an atom efficient, low temperature, environmentally benign process for the direct conversion of ethane to either of these molecules would circumvent the need for current practices and thereby represent an important milestone in the valorisation of natural gas. The heterogeneous catalyst system explored in this thesis is based upon zeolite (ZSM-5) catalysts, which may be modified via post synthesis deposition of either or both of iron and copper and are shown to selectively transform ethane to a variety of higher value products including but not limited to ethanol, acetaldehyde, acetic acid and ethene under mild, environmentally benign conditions (H2O2 as oxidant, water as solvent, temperatures of < 90 °C). C-C scission of C2 products led to formation of carbon centred radicals and yielded C1 products including methylhydroperoxide, methanol and formic acid, whilst deep oxidation yielded CO2, typically at selectivities of < 5%. The method by which catalysts were prepared was shown to impact significantly upon catalyst performance, with chemical vapour impregnation, a novel vapour deposition technique being shown to yield highly active catalysts. Investigations of reaction conditions such as ethane pressure, ethane partial pressure, temperature, oxidant concentration and catalyst mass [Chapter 1] III were conducted in a batch reaction system. All parameters were found to impact significantly upon both catalytic activity and product distributions allowing for directed selectivity to either ethanol or acetic acid as major product. Through extensive mechanistic studies, it was shown that a complex reaction scheme operates with these catalysts, which results in the primary C2 products ethanol, ethylhydroperoxide and ethene. Of these the former two were shown to undergo consecutive oxidation to acetaldehyde and acetic acid, whilst ethene was shown to react under test conditions to yield acetic acid. Additionally, upon deposition of Cu2+ onto ZSM-5 catalysts ethene was shown to become the major reaction product, with selectivities of 45.5% at 1.15% conversion. Following development under batch reaction conditions, the ZSM-5 catalysts were then applied under a continuous flow regime through co-feeding of an aqueous hydrogen peroxide solution and mixed ethane/ argon feed through a custom built fixed bed trickle bed reactor system. Through optimisation of…

▼ Initially, prostaglandins (PGs) were considered to only exist as free acid mediators. Although, formation of PG glycerol esters and PG ethanolamides by cellular cyclooxygenase (COX)-2 has been reported, generation of complex oxidised lipids via COX-1 has not been considered. In this study, formation of sixteen unique PG-containing phospholipids generated by agonist-activated human platelets is demonstrated using lipidomic approaches. Precursor scanning-tandem mass spectrometry identified a group of specific lipids comprising PGE2, PGD2 and two previously undescribed PG-like molecules (named PGb and PGc), attached to four phosphatidylethanolamine (PE) phospholipids (16:0p/, 18:1p/, 18:0p/ and 18:0a/). PGb and PGc were also detected as free eicosanoids and their structures remain to be characterised. These novel lipids formed within 2-5 minutes of platelet activation by thrombin, collagen or ionophore and required activation of several intracellular signalling intermediates, including cytosolic phospholipase A2 (cPLA2), p38 mitogen-activated protein kinase (MAPK), src tyrosine kinases, phospholipase C (PLC) and cytosolic calcium. Unlike free PGs that are secreted, PG-PEs remain cell associated, suggesting an autocrine mode of action. Aspirin supplementation in vivo (75 mg/day) or in vitro (1 mM) blocked their generation, indicating that COX-1 is required. Pharmacological studies using inhibitors of fatty acyl re-esterification significantly reduced formation of PG-PEs. Furthermore, purified COX-1 was unable to directly oxidise PE in vitro. Collectively, these indicate that PG-PEs are initially formed as free PGs via COX-1, and then rapidly esterified into PEs. In summary, this is the first demonstration of acute generation of PG-PEs in agonist-activated human platelets from endogenous substrate via COX-1. These unique lipids may represent additional bioactive molecules from this key platelet enzyme.

▼ This thesis investigates seafarers’ experiences of ill-treatment onboard ships. A sociological approach to ill-treatment is adopted, with a focus on characteristics of the work environment onboard which affect seafarers’ experiences of and responses to ill-treatment. A qualitative approach was employed to understand seafarers’ perceptions of ill-treatment. Semi-structured interviews based on the Negative Acts Questionnaire were conducted with seafarers and managerial personnel from one multinational and one Indian company. The seafarers were drawn from all ranks. Thematic analysis of the data revealed that seafarers’ perceptions, experiences and responses to ill-treatment were heavily influenced by characteristics of the work environment, including industry and company norms such as short-term contracts, the hierarchy, onboard, distance management and HR policies and training. Seafarers encountering ill-treatment can choose to exit their situation, raise their voice or remain silent. The findings showed that while support structures such as grievance procedures and union membership existed for seafarers experiencing ill-treatment, the majority of seafarers chose to remain silent because of complex interactions between a variety of workplace features. Fears included job insecurity, concern for career advancement, fear of blacklisting and personal financial concerns. Those seafarers that did choose to escape their situations found that there could be repercussions on their finances and their career ambitions, or that exercising their voice resulted in a reshuffle of seafarers but nothing of import changed. The professional socialisation process and culture onboard the ship are very important in influencing seafarers’ perceptions of ill-treatment, and play a role in the occurrence of preventative behaviour and use of coping mechanisms. In addition, the industry norms of short-term contracts, the purported manning crisis and a race to the bottom mentality force seafarers to be highly insecure in their jobs and encourage them to accept their situation until they can escape it.

▼ The research presented in this thesis describes the direct synthesis of hydrogen peroxide from H2 and O2 using supported palladium based catalysts. The direct synthesis of hydrogen peroxide offers a more straightforward and sustainable alternative to the current industrial anthraquinone autoxidation (AO) process. Au-Pd bimetallic catalysts have been proved to be highly active for the direct synthesis process. The work presented in this thesis attempted to produce less expensive catalysts through adding cheap secondary metal to Pd as an effective substitute to Au or using an effective preparation for a low metal loading of Au-Pd nanoparticles. In addition, a comprehension of the actual active sites over bimetallic and Pd monometallic particles for H2O2 direct synthesis was also attempted. The first part of this work aims to explain an interesting phenomenon – an increase of activity for H2O2 direct synthesis and a decrease of hydrogenation of H2O2 over carbon supported Ni-Pd bimetallic and Pd only catalysts after both hydrogen peroxide synthesis and storage under ambient conditions. Based on the results of XPS, XRD and CO-chemisorption integrated with previous publications, it was concluded that (i) both the reaction of hydrogen peroxide direct synthesis and catalyst storage led to an decrease of particle dispersion; (ii) relative to the active sites on high energy surfaces/small particles of Pd (0), those on low energy surfaces/large particles are more selective for H2O2 synthesis, as the latter demonstrates lower activity of dissociative adsorption of O2 and H2O2. The role of secondary metal-Ni added to Pd was also investigated for H2O2 direct synthesis in the thesis. For carbon supported Ni/Pd catalysts (including Ni monometallic, Pd monometallic and Ni-Pd bimetallic catalysts), the addition of Ni to Pd enhanced catalytic activity and selectivity for H2O2 synthesis. The results of MP-AES, XPS, XRD and TPR implied that metallic Pd may sit on the top of Ni oxides with a dissolution of metallic Ni in Pd to some degree. Electron transfer from Ni to Pd probably also occurred which was inferred by XPS analysis. The role of Ni in Pd for H2O2 direct synthesis was Preface III also investigated over TiO2 supported catalysts which led to an enhancement of H2O2 productivity, H2 conversion rate and H2O2 selectivity relative to Pd only catalyst. Based on the results of XPS, TPR and STEM, it was concluded that inactive Ni species diluted Pd sites as individual Pd atoms which are the selective active sites for H2O2 direct formation. The next part of the study addressed a modified impregnation method (MIm) for the preparation of Au-Pd nanoparticles. These nanoparticles have been proved previously by STEM which are well dispersed homogeneous particles because of excess amount of Cl- ions in the preparation. As a consequence, the resulted catalyst demonstrated a superior activity than conventional impregnation method (CIm) analogues even the latter loaded with a quintuple metal loading. Through tuning Pd metal loading in 1 wt% Au-Pd…

▼ This thesis presents a case study of Welsh innovation policy from the period of political devolution (1999) to the present day (2014), exploring the role of regional government as a driver of innovation and economic development. It proposes a multi-theoretical framework to be employed in the study of real world innovation interventions, to illicit nuanced insights into the Wales case study, and also to test the applicability of key regional innovation theories in a weaker region context. The four regional innovation theories identified as the most prominent in both academic literature and policy, and incorporated into the conceptual framework of this study are: systems of innovation, clusters, the learning region, and the triple helix. The case study presented consists of a systematic review of Welsh innovation and related policy since devolution and in-depth interviews with key stakeholders in the Welsh innovation system. The Welsh approach to innovation is found to have evolved in three distinct phases, whereby innovation is prioritised differently relative to other policy spheres, and the dominant approach to innovation varies over time. Innovation interventions have met with varying levels of success, and, interestingly, the most prominent approaches have been, on the whole, less successful in Wales. This thesis argues that no one theory is ideally suited to the analysis and development of innovation policy in weaker regions; instead it draws on the strengths of the four key theories identified. It argues against a “one-size-fits-all” approach to innovation policy, premised on exporting models from exceptional leading regions in a manner that is geographically, historically, and culturally blind. It supports a move away from normative approaches to the study and practice of innovation policy, instead drawing on the different theoretical elements that are particularly relevant to the case in question.

▼ This document contains three parts: a review of the literature relating to the subject area; an empirical review; and a reflective account. First, the literature review examines a selection of the literature relating to the conceptualization and measures of teacher-pupil relationships and also literature relating to the association between these relationships and a number of outcomes including children’s behaviour, academic attainment and engagement in the classroom. Secondly, the empirical review comprises a quantitative study carried out with a sample of 110 children and four teachers. It examines a specific construction of the teacher-pupil relationship, the classroom working alliance, investigating whether there is an association between children’s and teachers’ ratings of alliance and children’s ratings of classroom engagement. The study also examines whether children’s characteristics, specifically gender, have an effect on teachers’ and children’s ratings of alliance and/or engagement. Finally, the reflective account provides a more reflexive and personal exploration of the process of the research project. It includes: discussion of the inception of the research question and design; ethical and other issues that arose during the course of the study; possible implications for the practice of educational psychologists; and the contribution to knowledge at the level of personal professional development and also the contribution to the wider literature base.
