Justice, constructivism, and the egalitarian ethos

This thesis defends John Rawls’s constructivist theory of justice against three distinct challenges.
Part one addresses G. A. Cohen’s claim that Rawls’s constructivism is committed to a mistaken thesis about the relationship between facts and principles. It argues that Rawls’s constructivist procedure embodies substantial moral commitments, and offers an intra-normative reduction rather than a metaethical account. Rawls’s claims about the role of facts in moral theorizing in A Theory of Justice should be interpreted as suggesting that some of our moral beliefs, which we are inclined to hold without reference to facts, are, in fact, true, because certain facts obtain. This thesis and the acknowledgement of the moral assumptions of Rawls’s constructivism help to show that Rawls does not, and does not need to, deny Cohen’s thesis.
Part two defends the characterization of the decision problem in Rawls’s original position as a decision problem under uncertainty. Rawls stipulates that the denizens of the original position lack information that they could use to arrive at estimates of the likelihood of ending up in any given social position. It has been argued that Rawls does not have good grounds for this stipulation. I argue that given the nature of the value function we should attribute to the denizens of the original position and our cognitive limitations, which also apply to the denizens of the original position, their decision problem can be characterized as one under uncertainty even if we stipulate that they know that they have an equal chance of being in any individual’s place.
Part three assesses the claim that a true commitment to Rawls’s difference principle requires a further commitment to an egalitarian ethos. This egalitarian ethos is offered as a means to bring about equality and Pareto-optimality. Accordingly, I try to undermine the case for an egalitarian ethos by challenging the desirability of the ends it is supposed to further or by showing that it is redundant. I argue that if primary goods are the metric of justice, then Pareto optimality in the space of the metric of justice is undesirable. I then argue that if the metric of justice is welfare, depending on the theory of welfare we adopt, an egalitarian ethos will either be redundant or will have objectionably paternalistic consequences.

Procopius and the Persian Wars

This thesis takes as its focus book I of Procopius' Persian Wars in an attempt to investigate both the events it describes and the way in which they are reported.
A two-fold approach has therefore been employed, on the one hand dealing with the actual events, and on the other with Procopius' handling of them compared to that of other sources. While the first chapter thus considers Procopius himself and the genre of 'classicising' history, the second provides the fifth-century background to the events. Subsequent chapters generally consider the events in question first, before going on to examine Procopius' account in detail.
The third chapter investigates Procopius' information on Sasanian history and the Hephthalite Huns, which is remarkably detailed. The following chapter considers his account of the war waged against the Persians under the Emperor Anastasius (502-506), and concludes that he is offering a very partial account. Chapters five and six consider the centrepiece of Persian Wars I: the campaigns of 530 and 531, including Belisarius' victory at Dara and defeat at Callinicum. Close comparison with the chronicler John Malalas is undertaken in the case of the latter battle.
Chapter seven analyses Procopius' excursus into southern Arabian affairs. where he seems to have had access to good geographical and historical information. Chapter eight considers the final events reported in Persian Wars I, which, it is argued, were added at a later stage; his account of the Nika riot in Constantinople is omitted from consideration, but his final detailed excursus on internal Persian history and his report on the coup at Dara are examined.
A conclusion is offered at the end, emphasising the general accuracy of Procopius, particularly concerning events of his own day, and seeking to account for his selectiveness in the deployment of information.
Towards and understanding of the role of associative learning in risk for mental health problems

The ability to prioritize information enables us to think and take action without being overwhelmed by external stimuli or internal thoughts and feelings. Neuroticism is associated with altered processing of emotional information but differences in the processing of emotional information may arise from basic differences in information processing, such as altered processes of attention, changes in sensitivity to salient information, or differences in the ability to encode conjunctions of information. Through this thesis, I explore the relationship between neuroticism and processing of non-emotional information, with a particular focus on learning about combinations of information.
Associative learning paradigms were used to test ability to learn about combinations of information and neuroticism was observed to be associated with strong non-linear discrimination learning. The tendency to focus on specific details was associated with weak non-linear discrimination learning. A novel model of associative learning is presented, offering an account for how variation in the ability to engage in non-linear discrimination learning might be understood.
Mechanisms underlying the association between neuroticism and strong non-linear discrimination learning were explored. Neuroticism was not found to be associated with a tendency to focus on specific details or shifts in attention towards goal relevant information. Neuroticism was not found to be associated with enhanced ability to identify feature conjunctions, altered sensitivity to the relative validity of stimuli or pre-exposure of stimuli.
The importance of understanding individual differences in processes of associative and the value of associative learning tasks to look at information processing biases underlying neuroticism are discussed.

Beltway battles: ideology and infighting in US foreign policy toward the Middle East 2001-2006

The record of American foreign policy in the Middle East between 2001 and 2006 is marked mostly by failures of the Bush Administration to achieve its stated objectives, including reducing terrorism, stopping the spread of weapons of mass destruction, and spreading liberal democracy. Still, there are also notable bright spots, including the case of Libya’s diplomatic rehabilitation. What is it, then, that accounts for this success in the face of so many other failures where the policy goals were markedly similar? I argue that a partial explanation of this discrepancy can be found in the nature of infighting between ideological realists and neoconservatives within the foreign policy bureaucracy. In doing so, process tracing is used to examine policy development toward four country cases: Iraq, Iran, Lebanon, and Libya, with Libya acting as the control. The object of these case studies is to demonstrate existence of a previously undescribed model of bureaucratic infighting, based on competing ideological differences regarding the fundamental direction and conduct of US foreign policy. I call this the Ideological Infighting, or I2, Model. Whereas previous works of US foreign policy analysis have focused only on the roles of individuals’ ideology or on bureaucratic interests, this study unites both. In doing so, it describes the policy effects that result from ideological disagreements within the executive agencies, rather than viewing a presidential administration as an ideologically coherent entity. It also refines understandings of the relationship between the President and his advisors. Finally, although this work deals specifically with the Middle East, the model is generalizable to all areas of US foreign policy.

Own- versus other-race face perception

The experiments in this thesis used behavioural measures and event-related potentials (ERPs) to investigate the influence of race on face processing in the brain. Previous behavioural research has highlighted an own-race effect in face processing, whereby individuals are more accurate at recognizing own-race compared to other-race faces. The current Thesis examined the own-race effect at perceptual and neural levels. Social influences on the own-race effect were also investigated, such as other-race experience, anxiety and implicit social bias, as these may account for differential own- versus other-race face processing. The main aim of the experiments contained in this thesis was to delve deeper into the examination of own and other-race face perception through a series of original experiments. Participants performed a variety of perceptual discrimination and identification tasks, and completed measures of explicit other-race experience and implicit racial bias to record their perceptions of other-race individuals. Chapters 2-4 saw the development of a new paradigm that tested the own-race effect in perception, in contrast to traditional recognition memory investigations. In Chapter 2 the own-race effect was investigated developmentally and found across three age-groups, and was larger in the two older age-groups. Chapters 3 and 4 found that the own-race effect differed across racial groups, and that social variables such as other-race experience influenced the strength of the own-race effect. In the latter experimental chapters, ERPs revealed that the behavioural own-race effect was evident at a neural level. Chapter 7 demonstrated that face-related stages of processing in the brain were sensitive to race of face. In Chapters 8 and 9, the sensitivity of face processing to own and other-race emotional expression processing was also examined. The additional social factor of emotional expression was explored in order to further the investigation of socially relevant information processing from the face. Findings from the last two experimental chapters demonstrated differential emotional face processing for own- versus other-race faces. Confirming the findings of the behavioural experiments, own- versus other-race emotion processing varied across racial groups and was subject to social influences such as other-race experience, intergroup anxiety and implicit racial bias. Overall, behavioural and neural investigations of the own-race effect demonstrated the influence of social variables such as other-race experience, intergroup anxiety and implicit racial bias on the way in which individuals processed own- versus other-race faces in the human brain.

Unsteady heat transfer measurements in a rotating gas turbine stage

As the performance required of high pressure turbines continues to increase, there is a need to investigate many details of the flow which occur in a gas turbine stage that were previously overlooked. These include the effects of rotation and three-dimensional flow as well as unsteady effects due to the relative motion of the blade rows. In order to obtain a better understanding of the turbine flowfield a new transient facility has been commissioned in which aerodynamic and heat transfer measurements can be undertaken in a full stage turbine at engine representative conditions.
The previously used technique of measuring the heat transfer rate by mounting thin film gauges on models manufactured from machineable glass ceramic was not suitable for use on the rotor blade because of the high stress levels involved. An alternative technique has been developed in which a metal turbine blade is coated with an insulating layer of enamel and thin film gauges painted on top. The developments in signal processing and calibrations which were necessary for the use of this type of thin film gauge are discussed in detail.
Signal conditioning electronics have been developed which permit amplification of the thin film gauge output to a higher level within the rotating frame before transmission through a slipring. Extensive tests have been undertaken, in a purpose built spinning rig, to establish the effects of rotation on the performance and mechanical integrity of the instrumentation and associated electronics.
The heat transfer measurements recorded in the rotor facility to date are presented and compared with data from a previous two-dimensional simulation of wake passing flow on the mid-height section of the same blade.

Computational methods for the estimation of cardiac electrophysiological conduction parameters in a patient specific setting

Cardiovascular disease is the primary cause of death globally. Although this group encompasses a heterogeneous range of conditions, many of these diseases are associated with abnormalities in the cardiac electrical propagation. In these conditions, structural abnormalities in the form of scars and fibrotic tissue are known to play an important role, leading to a high individual variability in the exact disease mechanisms. Because of this, clinical interventions such as ablation therapy and CRT that work by modifying the electrical propagation should ideally be optimized on a patient specific basis. As a tool for optimizing these interventions, computational modelling and simulation of the heart have become increasingly important. However, in order to construct these models, a crucial step is the estimation of tissue conduction properties, which have a profound impact on the cardiac activation sequence predicted by simulations. Information about the conduction properties of the cardiac tissue can be gained from electrophysiological data, obtained using electroanatomical mapping systems. However, as in other clinical modalities, electrophysiological data are often sparse and noisy, and this results in high levels of uncertainty in the estimated quantities.
In this dissertation, we develop a methodology based on Bayesian inference, together with a computationally efficient model of electrical propagation to achieve two main aims: 1) to quantify values and associated uncertainty for different tissue conduction properties inferred from electroanatomical data, and 2) to design strategies to optimise the location and number of measurements required to maximise information and reduce uncertainty. The methodology is validated in several studies performed using simulated data obtained from image-based ventricular models, including realistic fibre orientation and conduction heterogeneities. Subsequently, by using the developed methodology to investigate how the uncertainty decreases in response to added measurements, we derive an a priori index for placing electrophysiological measurements in order to optimise the information content of the collected data. Results show that the derived index has a clear benefit in minimising the uncertainty of inferred conduction properties compared to a random distribution of measurements, suggesting that the methodology presented in this dissertation provides an important step towards improving the quality of the spatiotemporal information obtained using electroanatomical mapping.

Managing nature, producing cultures: Inuit participation, science and policy in wildlife governance in the Nunavut Territory, Canada

In this thesis, a critical analysis is proposed of the relationships between Inuit participation, science and policy in wildlife governance in the Nunavut Territory, Canada. This analysis situates the emergence of a participatory regime for the governance of wildlife in Nunavut, explores its performance and examines the relations between the ways in which wildlife governance arrangements are currently represented in policy and how they are played out in practice across the territory.
To pursue these objectives, this research draws upon a number of theoretical perspectives and methodological strategies poised at a crossroads between environmental geography, science and technology studies, political ecology and ecological anthropology. It combines participant observation, semi-directed interviews and literature-based searches with approaches to the study of actor-networks, hybrid forums and scientific practices associated with Latour and Callon, as well as with Foucauldian and post-Foucauldian analyses of power, governmentality and subjectivity.
This analysis suggests that the overall rationale within which wildlife governance operates in Nunavut remains largely based on a scientific and bureaucratic framework of resource management that poses significant barriers to the meaningful inclusion of Inuit views. In spite of their participation in wildlife governance through a range of institutional arrangements, consultation practices and research initiatives, the Inuit of Nunavut remain critical of the power relations embedded within existing schemes, where significant decision-making authority remains under the control of the territorial (or federal) government, and where asymmetries persist with regard to the capacity of various actors to produce and mediate their claims. In addition, while the use of Inuit knowledge, or Inuit Qaujimajatuqangit, in wildlife governance in Nunavut has produced some collaborative research and management endeavours, it has also crystallised a divide between ‘Inuit’ and ‘scientific’ knowledge, generated unresolved conflicts, fuelled mistrust among wildlife co-management partners and led to an overall limited inclusion of Inuit observations, values and beliefs in decision-making.

Moving & feeling

This thesis focuses on tactile perception and aims at a comprehensive analysis of its characteristics over the time-course of various goal-directed movements. Tactile perception is assessed by means of discrimination and detection paradigms, as well as event-related potentials (ERPs). The main question investigated throughout the thesis is: ‘What changes in tactile perception, if any, take place over the time course of a goal-directed movement?’ In Chapter 2, the mechanisms related to such identified changes are examined: a facilitatory one – attention, and an inhibitory one – suppression. The experiment in Chapter 3
tests, at a brain level, amongst several explanations of the experimental results outlined in Chapter 2: timing-based, effector-based, and modality-based attentional/suppressive influences. In Chapter 4, other naturalistic movements are investigated (i.e., the movements involved in juggling and throwing/catching a basketball).
The results indicate a lack of facilitation in the processing of tactile information during the preparatory phase of the movement. Furthermore, differential changes are identified in tactile perception over the execution phase of the movement: At a behavioural level, tactile sensitivity significantly declines over the execution phase of the movement (though the detection of incoming tactile stimulation is enhanced), while at a neuronal level the same period exhibits significantly enhanced responses to somatosensory stimulation.
The experiments reported here thus bring evidence in favour of a dissociation between detecting and discriminating what is felt while moving. These results suggest that the quality of what is felt while moving may not be important for movement and, at the same time, that different pathways in the brain may be responsible for detecting and discriminating what is felt over the time course of a goal-directed movement. Based on these findings, in Chapter 5, the implications of these results are discussed and directions for further research are outlined.

The power of time: old age and old men in ancient Greek drama

The study of old age in the humanities has developed significantly in the last few decades, but there is still much scope for progress. This thesis, therefore, seeks to contribute to the growing academic discourse in this area by considering ageing as it is represented in ancient Greek theatre. At the same time, it seeks to take its place within Classical Studies by developing new readings of the plays. To develop a context for its analysis, this study begins with consideration of the contemporary demographics, social position, and stage portrayal of old age, and following this dedicates a chapter to each of the four surviving fifth century dramatists. In Aiskhylos’ Agamemnon, old age emerges as a crucial element in choral self-identity, and an important component of the authority that they display. Following this, the thesis considers the chorus of Euripides’ Herakles, in particular its use of metadramatic language, and the impact this has on plot-development and the representation of their age. The next chapter, on Oidipous Koloneus, shifts to consideration of the protagonist. The old age of Oidipous emerges as a powerful driver of his mental and spiritual power, and forms a striking background to the exploration of his character. The final chapter of the thesis examines how mechanisms of renewal that old men undergo in Aristophanes’ comedies (Knights, Akharnians, Peace, Wasps, Birds) differ across the dramas, and the impact this difference has on their interpretations. Such reassessments of ancient dramatic texts through the lens of old age can provide significant insight into the complexity of old men’s characterisations and of their involvement in the dramas. At the same time (from a gerontological perspective), this thesis’ analysis contributes to the developing discussion of the history of ageing, and highlights the differences between the ancient and modern worlds in this respect.
