This thesis examines James Joyce’s Ulysses (1922) and early cinema (c. 1895-1920) through Merleau-Pontian phenomenology. Instead of arguing for lines of direct influence between specific films and particular parts of Ulysses, I show that Joyce’s text and selected early films and film genres exhibit parallel philosophies. Ulysses and early cinema share similar ideas on the embodied nature of perception, the close relationship between mind and body, the intermingling of the human and the mechanical, intersubjectivity, and the subject’s inherence in the world. All of these shared ideas are inherently phenomenological. My phenomenological position on the Joyce-and-cinema relationship is at odds with a popular strain of scholarship which cites impersonality, neutrality, and automatism as the key linking factors between early cinema and modernist literature (including Joyce).
‘Joyce-and-cinema’ studies is a relatively large, and growing, field; as is ‘modernism-and-cinema’ studies. As well as ploughing my own path through an already crowded area, I analyse the different trends present (both historically and currently) in each area of study. I also add to the scholarship on phenomenological film theory by analysing the work of phenomenologically inflected film-philosophers and suggesting some new ways in which Maurice Merleau-Ponty’s phenomenology might be used in the analysis of films and literature.
I provide close analyses of several episodes of Ulysses and pay particular attention to ‘Ithaca’, ‘Circe’, ‘Nausicaa’, and ‘Wandering Rocks’. Several of Charlie Chaplin’s Mutual films are analysed, as are a select number of films by George Méliès. I also look at other trick-films, Irish melodrama, panoramas, ‘phantom rides’, and local actuality films (especially Mitchell and Kenyon’s Living Dublin series). Proto-cinematic devices – the Mutoscope and stereoscope – are also included in my analyses.
Analysis of nonlinear systems : large-scale, time-varying, non-polynomial and uncertain properties
Keywords: Nonlinear Systems

This thesis introduces, develops and applies methods for analysing nonlinear systems with the multiple challenges of time-varying, non-polynomial, uncertain or large-scale proper- ties. Both computational and analytic methods using Lyapunov functions are developed and the methods are applied to a range of examples. Generalised Absolute stability is introduced, which is a method of treating polynomial systems with non polynomial, uncertain or time-varying feedback. Analysis is completed with Sum of Squares programming, and this method extends both the applicability of sum of squares as well as existing absolute stability theory. Perturbation methods for invariant Sum of Squares and Semidefinite programs are introduced, which significantly improves scalability of computations and al- lows sum of squares programming to be used for large scale systems. Finally, invariance principles are introduced for nonlinear, time-varying systems. The concept of trajectories leaving sets uniformly in time is introduced, which allows a non-autonomous version of Barbashin-Krasovskii theorem.
Recognizing describable attributes of textures and materials in the wild and clutter
Keywords: Image Classification
Computer Vision
Material Recognition
Texture Understanding

Visual textures play an important role in image understanding because theyare a key component of the semantic of many images. Furthermore, texture representations, which pool local image descriptors in an orderless manner, have hada tremendous impact in a wide range of computer vision problems, from texture recognition to object detection. In this thesis we make several contributions to the area of texture understanding.
First, we add a new semantic dimension to texture recognition. Instead of focusing on instance or material recognition, we propose a human-interpretable vocabulary of texture attributes, inspired from studies in Cognitive Science, to describe common texture patterns. We also develop a corresponding dataset, the Describable Texture Dataset (DTD), for benchmarking. We show that these texture attributes produce intuitive descriptions of textures. We also show that they can be used to extract a very low dimensional representation of any texture that is very effective in other texture analysis tasks, including improving the state-of-the art in material recognition on the most challenging datasets available today.
Second, we look at the problem of recognizing texture attributes and materials in realistic uncontrolled imaging conditions, including when textures appear in clutter. We build on top of the recently proposed Open Surfaces dataset, introduced by the graphics community, by deriving a corresponding benchmarks for material recognition. In addition to material labels, we also augment a subset of Open Surfaces with semantic attributes.
Third, we propose a novel texture representation, combining the recent advances in deep-learning with the power of Fisher Vector pooling. We provide thorough evaluation of the new representation, and revisit in general classic texture representations, including bag-of-visual-words, VLAD and the Fisher Vectors, in the context of deep learning. We show that these pooling mechanisms have excellent efficiency and generalisation properties if the convolutional layers of a deep model are used as local features. We obtain in this manner state-of-the-art performance in numerous datasets, both in texture recognition and image understanding in general. We show through our experiments that the proposed representation is an efficient way to apply deep features to image regions, and that it is an effective manner of transferring deep features from one domain to another.
The susceptibility of leopards Panthera pardus to trophy hunting

The trophy hunting of African leopards Panthera pardus pardus may generate revenue to help foster their conservation. However, leopards are sensitive to hunting and populations decline if overharvested. The practice therefore requires careful management grounded in robust estimates of population density/status. Camera-trap surveys are commonly used to establish leopard numbers, and may guide harvest quotas. However, such surveys are limited over wide spatial scales and many African governments lack resources to implement them.
In this thesis I explore the potential use of a harvest composition scheme applied to puma Puma concolor in North America, to monitor leopards. The method hinges on the susceptibility of different leopard cohorts to hunting and if this varies, then predictions can be made about harvest composition. Susceptibility is likely to be governed by space use, encounter rates with bait lures (a common method used to attract leopards to hunting hides) and hunter selectivity. Thus in this thesis I explore leopard susceptibility to these factors using a protected leopard population in northern Zululand, South Africa. In my first chapter I examine using scent lures in camera-trapping. Against a backdrop of a passive survey I show adult males, females and sub-adults are captured at similar rates compared to a passive survey using lures. The use of lures does not appear to violate closure assumptions or affect spatio-temporal patterning, but their use appears limited as density estimate precision is not improved.
My second chapter examines ecological (likelihood of encountering a hunter) and anthropogenic (attractiveness to hunters) susceptibility of leopards to trophy hunting. I show that adult males are the most susceptible cohort to hunting (sub-adults least susceptible). I then take the incident rates from ecological and anthropogenic models and create a theoretical harvest composition using population parameters of protected leopards.
My third data chapter departs from hunting susceptibility and examines determinants of leopard trophy package price across Africa. I show that factors such as trophy quality, outfitter leopard hunting reputation and hunt success have little impact on price determination. Instead, overall outfitter reputation and the number of charismatic species in a package are positively correlated with price. These results have important consequences on several sustainable leopard hunting schemes proposed in the literature.
Novelty detection with extreme value theory in vital-sign monitoring
Keywords: order statistics

patient monitoring

Every year in the UK, tens of thousands of hospital patients suffer adverse events, such as un- planned transfers to Intensive Therapy Units or unexpected cardiac arrests. Studies have shown that in a large majority of cases, significant physiological abnormalities can be observed within the 24-hour period preceding such events. Such warning signs may go unnoticed, if they occur between observations by the nursing staff, or are simply not identified as such. Timely detection of these warning signs and appropriate escalation schemes have been shown to improve both patient outcomes and the use of hospital resources, most notably by reducing patients’ length of stay.
Automated real-time early-warning systems appear to be cost-efficient answers to the need for continuous vital-sign monitoring. Traditionally, a limitation of such systems has been their sensitivity to noisy and artefactual measurements, resulting in false-alert rates that made them unusable in practice, or earned them the mistrust of clinical staff. Tarassenko et al. (2005) and Hann (2008) proposed a novelty detection approach to the problem of continuous vital- sign monitoring, which, in a clinical trial, was shown to yield clinically acceptable false alert rates. In this approach, an observation is compared to a data fusion model, and its “normality” assessed by comparing a chosen statistic to a pre-set threshold. The method, while informed by large amounts of training data, has a number of heuristic aspects.
This thesis proposes a principled approach to multivariate novelty detection in stochastic time- series, where novelty scores have a probabilistic interpretation, and are explicitly linked to the starting assumptions made. Our approach stems from the observation that novelty detection using complex multivariate, multimodal generative models is generally an ill-defined problem when attempted in the data space. In situations where “novel” is equivalent to “improbable with respect to a probability distribution ”, formulating the problem in a univariate probability space allows us to use classical results of univariate statistical theory. Specifically, we propose a multivariate extension to extreme value theory and, more generally, order statistics, suitable for performing novelty detection in time-series generated from a multivariate, possibly multimodal model.
All the methods introduced in this thesis are applied to a vital-sign monitoring problem and compared to the existing method of choice. We show that it is possible to outperform the existing method while retaining a probabilistic interpretation.
In addition to their application to novelty detection for vital-sign monitoring, contributions in this thesis to existing extreme value theory and order statistics are also valid in the broader context of data-modelling, and may be useful for analysing data from other complex systems.
Hominin dispersals and the middle palaeolithic of Arabia
Keywords: middle palaeolithic

This thesis tests models on the dispersal of hominin populations in the Upper Pleistocene, specifically in relation to the Arabian Peninsula. It does so by conducting a quantified comparison of lithic assemblages from northeast Africa and southwest Asia. Lithic data from new excavations at the Jubbah Palaeolake in northern Saudi Arabia is compared to assemblages from Ethiopia, Sudan, Egypt, Jordan, Iran, Oman and other localities in Saudi Arabia. This is the first detailed inter-regional study of this area for Marine Isotope Stages 5 to 3, a critical spatial and temporal context in debates on both early modern human and Neanderthal demography and dispersal. The spatial and temporal character of the rich Arabian archaeological record correlate with emerging evidence for environmental change in Arabia; in particular the repeated dating of archaeological contexts to periods of climatic amelioration suggests that demographic growth was associated with periods of increased precipitation. The various factors influencing lithic variability and the methodologies by which they can be elucidated are reviewed. In particular this highlights the need for quantified and comparative analyses. A variety of analytical approaches are applied in this thesis, including the use of Correspondence and Principal Components Analyses to develop a nuanced view of lithic variability. Variability in cores is shown to largely reflect the related factors of size and reduction intensity. With analyses of debitage and retouched lithics a broadly similar picture emerges: assemblages which are heavily reduced have small cores and blanks and higher levels of retouch, and elements of shape variation also change in relation to reduction intensity. Elements of residual variability may reflect cultural differences. While it is felt that the evidence presented broadly orientates the Upper Pleistocene Middle Palaeolithic of Arabia to dispersals from Africa, this suggestion is subsumed with a problematization of using lithic evidence to understand dispersals. Aside from the need for further dated archaeological material from Arabia and surrounding countries, lithic analyses need to more thoroughly consider factors such as reduction intensity if we are to make robust inferences on population dispersals.
Dark energy and the inhomogeneous universe

Gibbs sampling

In this thesis, I study the relativistic effects of matter inhomogeneities on the accelerating expansion of the Universe. The acceleration is often taken to be caused by the presence of an exotic fluid called Dark Energy, or else a non-zero 'cosmological constant' term in the field equations of General Relativity. I consider whether this result could instead be an artefact caused by using an incorrect model to interpret observations. The standard 'concordance' cosmological model assumes the Cosmological Principle, which states that the matter distribution on large scales is homogeneous. One possibility is that correction terms appear in the field equations when small-scale inhomogeneities are smoothed over to produce this homogeneous model. These 'backreaction' effects could affect the dynamics of the spacetime, causing an apparent acceleration. I clarify the relationship between acceleration of the averaged spacetime and acceleration inferred from observable quantities, and show that they are closely related in statistically-homogeneous spacetimes.
Another possibility is that the Universe could be inhomogeneous on large scales. If there was a large ‘void’, with us at the centre, the lensing of light by the void could reproduce the observations that imply cosmic acceleration. I show that a popular class of void models, based on spherically-symmetric Lemaitre-Tolman-Bondi spacetimes, are unable to simultaneously fit a selection of observational data, thus effectively ruling-out this possibility. These data include the Kinematic Sunyaev-Zel'dovich (KSZ) effect, which is a distortion/shift of the Cosmic Microwave Background (CMB) frequency spectrum caused by the Compton scattering of photons by hot gas in galaxy clusters. This, and other distortions of the CMB frequency spectrum, are sensitive to the degree of anisotropy in the CMB about a scattering cluster. I suggest tests involving these observables that exploit the strong link between isotropy and homogeneity to (a) distinguish between different causes of a deviation from spatial flatness on the horizon scale, and (b) potentially confirm the Cosmological Principle using observations. Finally, I describe a novel Bayesian CMB component separation method for extracting the Sunyaev-Zel'dovich signal of clusters from CMB sky maps.
The power of legitimacy: local cooperation and the effectiveness of peace operations
Keywords: Cambodia

legitimacy

power

This thesis investigates how peace operations work. It contributes to the larger study of peace operation effectiveness by analysing the processes through which these institutions influence local actors in postconflict societies. Looking beyond traditional concerns with mandates and resources, it aims to understand how a peace operation seeks to achieve its goals, focusing on why local populations might cooperate with or obstruct its activities.
The thesis draws on theories of social power, compliance and legitimation to answer four central questions: what power do peace operations have to achieve their objectives? From where do peace operations derive power? How do local perceptions of an operation enable or constrain its effectiveness? How are peace operations legitimised at the local level, and with what effect?
It begins by critically reviewing the academic literature, arguing that existing approaches are unable to account for important dimensions of peace operation effectiveness because they neglect the local setting in which operations pursue their goals, and the extent to which the achievement of those goals requires local cooperation. It then develops an analytical framework to examine the processes of coercion, inducement and legitimacy through which peace operations seek to shape the decisions and actions of local actors.
This power-legitimacy framework is applied to study the effectiveness of the United Nations Transitional Authority in Cambodia (UNTAC) and the Regional Assistance Mission in Solomon Islands (RAMSI). By comparing variation in local cooperation between and within these cases, the thesis shows that the way a peace operation is locally perceived is an important but often overlooked determinant of its effectiveness. In particular, when local actors perceive a peace operation to be legitimate, they are more likely to behave in ways that assist the operation to achieve its goals. The thesis concludes by discussing the implications of this finding for the future study and practice of peace operations.
Satire in the Old Testament

Satire

In recent years, through the process of narrative and literary criticism, scholars have begun suggesting that satire is present in specific texts of the Old Testament. Thus the primary function of this thesis is to analyse the validity of these arguments alongside suggesting different places where satire may be found. To achieve this goal, the thesis begins by analysing and defining satire as a concept. A clear definition provides the thesis with the method needed to identify satire in texts which predate any defined understanding of the concept. The thesis also uses satirical works from throughout history as templates for understanding similar types of satire within the biblical works.
Once this methodology has been established, different genres of the Old Testament form the different chapters of the thesis. It identifies four different places where satire is deployed. Thus it examines satire in narratives, the book of Jonah, prophetic texts and wisdom literature. Each chapter combines new ideas with the analysis of previous scholastic arguments concerning the presence of satire. Within each genre a different type of satire with a range of complexity is deployed. The idol critiques in prophetic texts show simplistic satire. Narrative satire shows both situational and character-based satire. The book of Jonah is an example of hypocritical satire. Finally, satire in the wisdom literature contains a range of different satirical styles.
The thesis concludes that satire is present within the texts of the Old Testament. This has implication to the field of satire. It affirms the existence of pre-Hellenistic satire. Alongside this, it shows that satire is a subconscious human technique, deployable even when the proponent has no defined understanding of the concept. In the field of Old Testament studies it provides an alternative reading of many familiar texts. A satirical reading provides clear insight into authorial intent as well as offering different interpretations of the texts which are examined.

In this thesis a reduced dimensionality quantum scattering model is applied to the study of polyatomic reactions of type X + CH4 <--> XH + CH3.
Two dimensional quantum scattering of the symmetric hydrogen exchange reaction CH3+CH4 <--> CH4+CH3 is performed on an 18-parameter double-Morse analytical function derived from ab initio calculations at the CCSD(T)/cc-pVTZ//MP2/cc-pVTZ level of theory. Spectator mode motion is approximately treated via inclusion of curvilinear or rectilinear projected zero-point energies in the potential surface. The close-coupled equations are solved using R-matrix propagation. The state-to-state probabilities and integral and differential cross sections show the reaction to be primarily vibrationally adiabatic and backwards scattered. Quantum properties such as heavy-light-heavy oscillating reactivity and resonance features significantly influence the reaction dynamics. Deuterium substitution at the primary site is the dominant kinetic isotope effect. Thermal rate constants are in excellent agreement with experiment.
The method is also applied to the study of electronically nonadiabatic transitions in the CH3 + HCl <--> CH4 + Cl(2PJ) reaction. Electrovibrational basis sets are used to construct the close-coupled equations, which are solved via Rmatrix propagation using a system of three potential energy surfaces coupled by spin-orbit interaction. Ground and excited electronic surfaces are developed using a 29-parameter double-Morse function with ab initio data at the CCSD(T)/ccpV( Q+d)Z-dk//MP2/cc-pV(T+d)Z-dk level of theory, and with basis set extrapolated data, both corrected via curvilinear projected spectator zero-point energies. Coupling surfaces are developed by fitting MCSCF/cc-pV(T+d)Z-dk ab initio spin orbit constants to 8-parameter functions. Scattering calculations are performed for the ground adiabatic and coupled surface models, and reaction probabilities, thermal rate constants and integral and differential cross sections are presented. Thermal rate constants on the basis set extrapolated surface are in excellent agreement with experiment. Characterisation of electronically nonadiabatic nonreactive and reactive transitions indicate the close correlation between vibrational excitation and nonadiabatic transition. A model for comparing the nonadiabatic cross section branching ratio to experiment is discussed.
