Royalty and public in Britain

The thesis sets out to examine the interaction between the British royal family and its 'public' in the period between the Hanoverian succession and the recovery of George in from 'insanity' in 1789. Throughout, emphasis is given to the reception of royal activity by the press, who circulated information around the kingdom. It argues that the emergence of the domestic, popular monarchy in the middle of the reign of George III was the result of longterm considerations which arose from the activities of earlier generations of eighteenthcentury royalty, and were further developed by George III and his siblings. The growth of the royal family, and the physical and social limitations of the eighteenth-century court, led to its members finding avenues for self-expression outside the court and consequently to the expansion of the public sphere of the royal family.
The subject is approached through six chapters: the move from traditional - usually sacerdotal - manifestations of royal benevolence, to sponsorship of voluntary hospitals and similar charities; accession and coronation celebrations during the century; royal public appearances in general, including the theatre and the masquerade, as well as visits to the provinces; the royal residences; royal support for scientific endeavour; and the legacy of the seventeenth century on eighteenth-century royalty, including portraiture and the family's martial connections, and the appearance or absence of mythologized seventeenth-century images in relation to the Thanksgiving of 1789.
The thesis is intended to complement recent work on the emergence of national consciousness in Britain in the eighteenth century, as well as on royalty itself. It attempts to identify some of the questions concerning the place the royal family had in the society of eighteenth-century Britain, how its public image reflected that context, and how this helped the monarchy to survive as a stronger institution.
Miscible flow through porous media

This thesis is concerned with the modelling of miscible fluid flow through porous media, with the intended application being the displacement of oil from a reservoir by a solvent with which the oil is miscible. The primary difficulty that we encounter with such modelling is the existence of a fingering instability that arises from the viscosity and the density differences between the oil and solvent. We take as our basic model the Peaceman model, which we derive from first principles as the combination of Darcy’s law with the mass transport of solvent by advection and hydrodynamic dispersion. In the oil industry, advection is usually dominant, so that the Peclet number, Pe, is large. We begin by neglecting the effect of density differences between the two fluids and concentrate only on the viscous fingering instability. A stability analysis and numerical simulations are used to show that the wavelength of the instability is proportional to Pe−1/2, and hence that a large number of fingers will be formed. We next apply homogenisation theory to investigate the evolution of the average concentration of solvent when the mean flow is one-dimensional, and discuss the rationale behind the Koval model. We then attempt to explain why the mixing zone in which fingering is present grows at the observed rate, which is different from that predicted by a naıve version of the Koval model. We associate the shocks that appear in our homogenised model with the tips and roots of the fingers, the tip-regions being modelled by Saffman-Taylor finger solutions. We then extend our model to consider flow through porous media that are heterogeneous at the macroscopic scale, and where the mean flow is not onedimensional. We compare our model with that of Todd & Longstaff and also models for immiscible flow through porous media. Finally, we extend our work to consider miscible displacements in which both density and viscosity differences between the two fluids are relevant.
Determinants of neuronal firing patterns in the hippocampus

The activity of networks subserving memory and learning in the hippocampus is under the control of GABAergic interneurons. In order to test the contribution of distinct cell types, I have recorded extracellularly, labelled, and identified different types of interneuron in area CA3 of the hippocampus, a region implicated in the generation of gamma and theta oscillations, and the initiation of sharp-waves.
I present here a detailed analysis of the spike timing of parvalbumin-positive (PV) basket and physiologically identified pyramidal cells in area CA3, relative to various network states recorded in area CA3 and CA1 simultaneously. Additionally, I have shown by detailed analysis that five classes of previously recorded and identified CA1 interneuron fired with cell type specific firing patterns relative to local gamma oscillations.
In CA3, PV basket cells fired phase locked to theta and gamma oscillations recorded in CA1 as well as in CA3, and increased their firing rates during CA1 sharp-waves. Pyramidal cells in CA3 were also phase-locked, but fired at phases different from basket cells. During theta oscillations, CA3 pyramidal and PV basket cells were phase locked to both CA1 and CA3 theta equally, suggesting a wide coherence of these oscillations; in contrast, cells fired more strongly phase-locked to gamma oscillations in CA3 than in CA1, suggesting a specific role for CA3 in the generation of this rhythm. In contrast to theta and gamma oscillations, CA3 basket cells were phase-locked to ripples in area CA3 but not in CA1.
Overall, my results show that the spike timing of several types of interneuron in CA1, and PV basket cells in CA3, is correlated in a cell- and area-specific manner with the generation of particular states of synchronous activity.

Topics on backward stochastic differential equations. Theoretical and practical aspects

This doctoral thesis is concerned with some theoretical and practical questions related to backward stochastic differential equations (BSDEs) and more specifically their connection with some parabolic partial differential equations (PDEs). The thesis is made of three parts.
In the first part, we study the probabilistic representation for a class of multidimensional PDEs with quadratic nonlinearities of a special form. We obtain a representation formula for the PDE solution in terms of the solutions to a Lipschitz BSDE. We then use this representation to obtain an estimate on the gradient of the PDE solutions by probabilistic means. In the course of our analysis, we are led to prove some results for the associated multidimensional quadratic BSDEs, namely an existence result and a partial uniqueness result.
In the second part, we study the well-posedness of a very general quadratic reflected BSDE driven by a continuous martingale. We obtain the comparison theorem, the special comparison theorem for reflected BSDEs (which allows to compare the increasing processes of two solutions), the uniqueness and existence of solutions, as well as a stability result. The comparison theorem (from which uniqueness follows) and the special comparison theorem are obtained through natural techniques and minimal assumptions. The existence is based on a perturbative procedure, and holds for a driver whis is Lipschitz, or slightly-superlinear, or monotone with arbitrary growth in y. Finally, we obtain a stability result, which gives in particular a local Lipschitz estimate in BMO for the martingale part of the solution.
In the third and last part, we study the time-discretization of BSDEs having nonlinearities that are monotone but with polynomial growth in the primary variable. We show that in that case, the explicit Euler scheme is likely to diverge, while the implicit scheme converges. In fact, by studying the family of θ-schemes, which are mixed explicit-implicit, θ characterizing the degree of implicitness, we find that the scheme converges when the implicit component is dominant (θ ≥ 1/2 ). We then propose a tamed explicit scheme, which converges. We show that the implicit-dominant schemes with θ > 1/2 and our tamed explicit scheme converge with order 1/2 , while the trapezoidal scheme (θ = 1/2) converges with order 7/4.

A tale of two citizenships

This thesis examines the development of citizenship as a political concept in twentieth-century Britain, by considering how different political and intellectual circumstances shaped changes in ideas about citizenship. By examining how and why the conception of citizenship formulated in the early twentieth century by the idealist philosopher Henry Jones (1852-1922), differed from that articulated by the sociologist and theorist of the post-war welfare state T. H. Marshall (1893-1981) in the years after the Second World War, the work identifies a process by which changing structures of thought shifted the meaning of citizenship over the years.
The thesis consists of three major sections. In the first section, the contrasting personal histories of Jones and Marshall are presented. The effects of different social realities and personal contexts on the production of political ideas are considered. The next section then examines the different idea environments within which Jones and Marshall developed their thought. The differences between the idealist intellectual framework represented by Jones, and the systematic sociological approach represented by Marshall, are mapped out. Finally, the conceptual structures of the two different conceptions of citizenship that emerged in Britain in the course of the twentieth century are examined; and the way in which changing ideas about citizenship were played out in practical debates over social policy is outlined in an analysis of the debates over the Royal Commission on the Poor Laws of 1905-9 and the 1948 National Assistance Act.
By unravelling the intellectual and ideological processes that have occurred in the development and articulation of particular conceptions of citizenship, the work makes an original contribution to historical understandings of the distinction between 'idealist' and 'positivist' idea structures in twentieth-century Britain, and of the role played by such structures in shaping the development of the welfare state as a policy option.

Investigation of in-hospital norovirus transmission using whole genome sequencing

Norovirus is the commonest cause of viral gastroenteritis, affecting all age groups worldwide. Outbreaks frequently occur in semi-closed communities such as schools, cruise ships, prisons and hospitals. Within the healthcare environment, the economic and logistical burdens and the inconvenience caused by norovirus is significant, since ward closure remains central to infection control. The aim of this study was to investigate norovirus transmission dynamics during hospital outbreaks. The ultimate goal was to provide information that could, in future, lead to the development of novel, less disruptive approaches to curtailing the spread of infection.
The study explored the application of 'next generation' high throughput DNA sequencing technologies to the determination of large numbers of norovirus genomes. Whole genome sequences provide the highest possible level of discrimination among viruses, information which is essential to the identification of linked and independent cases of infection. The approach exploits the high norovirus mutation rate, which is typical of RNA viruses. Consequently, viruses within a single ward which differ by more than a few SNVs can be considered to represent independent introductions, rather than a single outbreak.
Whole genome sequence data (determined for noroviruses collected between 2009 and 2013) were combined with epidemiological data, providing further insights into transmission dynamics. These data identified multiple independent virus introductions during single ward outbreaks. The possible origin of such outbreaks in Oxfordshire hospitals were investigated using viruses originating in the local community, and in other healthcare environments distributed throughout the UK. Whole genome sequences of noroviruses from consecutive years were genetically divergent, confirming the rapid evolution of the virus over time and excluding the possibility of prolonged environmental contamination as a reservoir of infection. Such detailed information on norovirus transmission within the healthcare environment could inform alternative future approaches to optimising infection control within the healthcare setting.

Supersymmetry breaking in 4D string theory

In this thesis we address the problem of supersymmetry breaking in four dimensional string theory. We derive an effective Lagrangian describing the low energy degrees of freedom including the Goldstone mode associated with the spontaneously broken R-symmetry when a gaugino condensate forms.
We show the equivalence between our approach and those previously used for studying gaugino condensate in 4D string theory but we also show the need to include quantum effects due to the strong coupling constant in the hidden sector.
We determine the vacuum structure of the complete scalar potential and show that supersymmetry is broken and a large mass hierarchy may develop with a single gaugino condensate. Realistic phenomenological values for the gauge coupling constant, unification scale and soft supersymmetric breaking terms can be obtained. Consistency with the minimal supersymmetric extension of the standard model requires the hidden gauge group to be SU(6) or SO(9).

Studies in the history and function of the British theatre playbill and programme 1564-1914

This thesis offers a comprehensive account of the history, forms and content of playbills and theatre programmes; of the different contexts of their physical production, dispersal and varied uses; and, beyond their immediate utility as a record of author, work, cast, place and time of performance, considers the evidence they yield of the social contexts of theatregoing. Chapter one demonstrates the ways in which diverse approaches to the classification of playbills and programmes facilitate an understanding of their most basic ingredients. Chapter two offers an account of the production and distribution of playbills and programmes from the mid-sixteenth through the early-twentieth centuries. Chapter three explores the relationship between bills of the play and other theatrical documentation. The historical considerations undertaken in the second section, chapters four through six, represent a chronological overview of the numerous developments to the form and content of the British theatre bill occurring between 1564 and 1914. The functional considerations undertaken in the final section offer an analysis of the duties fulfilled by the British theatre bill, before, during and after a production. Chapter seven is concerned with the role of the playbill in anticipation of the future, as a source of both allure and information. Chapter eight examines the role of the programme in conjunction with the present, as a guide to both the play and the theatre. Chapter nine concludes the study, discussing the role of the bill of the play in reflection on the past, as a chronicler of both theatre history and social history.

Mathematical modelling of compaction and diagenesis in sedimentary basins

Sedimentary basins form when water-borne sediments in shallow seas are deposited over periods of millions of years. Sediments compact under their own weight, causing the expulsion of pore water. If this expulsion is sufficiently slow, overpressuring can result, a phenomenon which is of concern in oil drilling operations. The competition between pore water expulsion and burial is complicated by a variety of factors, which include diagenesis (clay dewatering), and different modes (elastic or viscous) of rheological deformation via compaction and pressure solution, which may also include hysteresis in the constitutive behaviours. This thesis is concerned with models which can describe the evolution of porosity and pore pressure in sedimentary basins.
We begin by analysing the simplest case of poroelastic compaction which in a 1-D case results in a nonlinear diffusion equation, controlled principally by a dimensionless parameter lambda, which is the ratio of the hydraulic conductivity to the sedimentation rate. We provide analytic and numerical results for both large and small lambda in Chapter 3 and Chapter 4. We then put a more realistic rheological relation with hysteresis into the model and investigate its effects during loading and unloading in Chapter 5. A discontinuous porosity profile may occur if the unloaded system is reloaded. We pursue the model further by considering diagenesis as a dehydration model in Chapter 6, then we extend it to a more realistic dissolution-precipitation reaction-transport model in Chapter 7 by including most of the known physics and chemistry derived from experimental studies.
We eventually derive a viscous compaction model for pressure solution in sedimentary basins in Chapter 8, and show how the model suggests radically different behaviours in the distinct limits of slow and fast compaction. When lambda << 1, compaction is limited to a basal boundary layer. When lambda >> 1, compaction occurs throughout the basin, and the basic equilibrium solution near the surface is a near parabolic profile of porosity. But it is only valid to a finite depth where the permeability has decreased sufficiently, and a transition occurs, marking a switch from a normally pressured environment to one with high pore pressures.

Topics in the economics of money substitutes in developing and transition countries

Recent research has shown that money substitutes - whether in the form of foreign currency or of more exotic instruments such as privately-issued moneys - are common in developing and transition countries, and have important consequences for macroeconomic and financial sector policy. The aim of this thesis is to advance our theoretical and empirical understanding of the determinants of money substitution in developing and transition economies.
We begin in Chapter 1 by addressing the need for a general theoretical framework for the analysis of money substitutes. Reviewing both the classical and the modern theoretical literature on money, we conclude that the Credit theory of money - an ancient but until recently neglected theory which conceives of money as a unilateral financial contract between its issuer and its bearer - is a useful framework for such analysis.
In Chapter 2, we undertake an empirical analysis of non-cash settlements (NCS) in Croatia. Using time series econometric analysis, we demonstrate that the instruments used to settle NCS are at least in part substitutes for the national currency, created endogenously by the enterprise sector in response to constraints on their participation in the official monetary and banking system.
We turn to the most important form of money substitute in developing and transition countries - foreign currency - in Chapter 3, where we present a new review of the theoretical and empirical literature on dollarisation. In particular, we track the evolution of theoretical models of dollarisation in response to the increasing empirical importance of financial dollarisation relative to currency substitution.
In Chapter 4 we undertake an empirical study of the determinants of deposit dollarisation in the two transition economies of Estonia and Lithuania by building and interpreting dynamic, multiple equation, econometric models. We find that a simple, portfolio theoretic account of the dollarisation process furnishes a good explanation, but also that data availability limits the level of analytical detail that this approach can attain.

In pursuit of salvation: Woodrow Wilson and American liberal internationalism as secularized eschatology

This work reinterprets the idea of progress at the heart of Woodrow Wilson’s liberal internationalism through the lens of secularization theory, which holds that modern philosophies of progress stand on religious foundations and represent secularized vestiges of biblical eschatology. Previous applications of this insight reveal a selective pattern: Whereas totalitarian and illiberal narratives of progress such as Nazism and Marxism-Leninism have received lavish attention and spawned extensive political religions literature, liberal progressivism has been ignored. This dissertation rectifies this neglect. Initial chapters present the biblical conception of history as the myth of salvation, introduce secularization through the writings of Karl Löwith and Hans Blumenberg, respectively its principal proponent and main critic, and test the limits of the concept to confirm its applicability to liberal progressivism. The main part aims secularization theory at Wilson’s idea of progress in the broader context of American liberal thought. From the 17th-century Puritan vision of a “city upon a hill” to the 19th-century doctrine of “manifest destiny”, biblical eschatology defined the way Americans envisioned history and their role in it, giving rise to a sort of liberal-republican millennialism. Wilson was no exception: Considering faith essential to authentic knowledge, he regarded history as a providential process, the United States as a divinely appointed redeemer nation, and himself as a Christian statesman performing God’s work in a fallen world. His foreign policy was fundamentally a religious mission to transform international relations according to the Bible, thereby fulfilling the prophecy of salvation. The dissertation demonstrates the eschatological foundations of his statecraft through specific examples and draws attention to their illiberal and totalizing implications. Final passages note the enduring relevance of Wilson’s principles and, based on their reinterpretation in this work, reflect critically on their suitability as a guide for future American foreign policy.

Rhodium catalysed hydroacylation reactions in the synthesis of heterocycles

Rhodium-catalysed hydroacylation provides a highly atom economic synthesis of ketone products from the combination of aldehydes and multiple bond systems by C-H bond activation. This work evaluates the combination of intermolecular hydroacylation for the synthesis of classical heterocycle precursors and their dehydrative cyclisation to give rise to a range of substituted heterocyclic compounds.
Chapter 1 outlines recent developments in the chemistry of hydroacylation. Particular attention is paid to the various chelation strategies employed in intermolecular hydroacylation. Chapter 2 discusses some relevant and recent developments in the field of pyridine and pyrrole synthesis.
Having established that β-sulphur chelation controlled hydroacylation can be used to synthesise pyridines in Chapter 3; attention was turned to hydroacylation of propargyl amines in Chapter 4. The methodology was expanded to provide a synthesis of γ-amino enones. The hydroacylation reaction and cyclisation is combined in a procedure that utilises thermal Boc-deprotection and cyclisation to give a range of highly-substituted pyrroles.
The regioselectivity of the hydroacylation of propargyl amines is investigated in Chapter 5 by application of statistical Design of Experiments methodology. Optimised conditions were identified with minor improvements in the selectivity of the reaction.
