Aetius of Amida. Libri Medicinales Book 1: A Translation with Commentary

This work is the first translation into a modern language of book 1 of the Libri Medicinales of Aëtius of Amida, a Byzantine physician who wrote in the middle of the 6th century AD. It comprises a lengthy preface, describing the analysis of pharmacological materials in terms of the science of the time, followed by 418 chapters, listing such materials obtained from plants. Commentary is to be found in the Introduction, as well as a running commentary after each part of the preface and each chapter. As Aëtius’ book 1 is a synopsis of the plants section of Galen’s On the Mixtures and Capacities of Simple Drugs, particular attention is paid to comparison between Aëtius’ work and that of Galen. Evaluation of the efficacy and safety of the ancient drugs in the light of modern scientific knowledge, a relatively neglected area of research, has also been given serious consideration.

Cassius Dio's speeches and the collapse of the Roman Republic

This thesis argues that Cassius Dio used his speeches of his Late Republican and Augustan narratives as a means of historical explanation. I suggest that the interpretative framework which the historian applied to the causes and success of constitutional change can be most clearly identified in the speeches. The discussion is divided into eight chapters over two sections. Chapter 1 (Introduction) sets out the historical, paideutic, and compositional issues which have traditionally served as a basis for rejecting the explanatory and interpretative value of the speeches in Dio’s work and for criticising his Roman History more generally. Section 1 consists of three methodological chapters which respond to these issues. In Chapter 2 (Speeches and Sources) I argue that Dio’s prosopopoeiai approximate more closely with the political oratory of that period than has traditionally been recognised. Chapter 3 (Dio and the Sophistic) argues that Cassius Dio viewed the artifice of rhetoric as a particular danger in his own time. I demonstrate that this preoccupation informed, credibly, his presentation of political oratory in the Late Republic and of its destructive consequences. Chapter 4 (Dio and the Progymnasmata) argues that although the texts of the progymnasmata in which Dio will have been educated clearly encouraged invention with a strongly moralising focus, it is precisely his reliance on these aspects of rhetorical education which would have rendered his interpretations persuasive to a contemporary audience. Section 2 is formed of three case-studies. In Chapter 5 (The Defence of the Republic) I explore how Dio placed speeches-in-character at three Republican constitutional crises to set out an imagined case for the preservation of that system. This case, I argue, is deliberately unconvincing: the historian uses these to elaborate the problems of the distribution of power and the noxious influence of φθόνος and φιλοτιμία. Chapter 6 (The Enemies of the Republic) examines the explanatory role of Dio’s speeches from the opposite perspective. It investigates Dio’s placement of dishonest speech into the mouths of military figures to make his own distinctive argument about the role of imperialism in the fragmentation of the res publica. Chapter 7 (Speech after the Settlement) argues that Cassius Dio used his three speeches of the Augustan age to demonstrate how a distinctive combination of Augustan virtues directly counteracted the negative aspects of Republican political and rhetorical culture which the previous two case-studies had explored. Indeed, in Dio’s account of Augustus the failures of the res publica are reinvented as positive forces which work in concert with Augustan ἀρετή to secure beneficial constitutional change.

Speech and narrative: characterisation techniques in the "Aeneid"

The thesis provides a comprehensive analysis of the characterisation of two of the major figures in the Aeneid, Aeneas and Turnus. Particular attention is paid to their direct speeches, all of which are examined and, where relevant, compared to Homeric models and parallels. To this purpose considerable use is made of the indices in Knauer's Die Aeneis und Homer. A more general comparison is made between the dramatic (direct speech) role of Aeneas and those of Homer's Achilles (Iliad) and Odysseus (Odyssey). An appraisal is made (from the viewpoint of depiction of character) of the relationship between the direct and indirect speeches in the Aeneid. Reasons are given to suggest that it is not mere chance, or for the sake of variety, that certain speeches of Aeneas and Turnus are expressed in oratio obliqua. In addition, the narrative portrayal of Aeneas and Turnus is considered in apposition to that of the speeches. A distinction is drawn between Vergil's direct method of characterisation (direct speeches) and his indirect methods (narrative/oratio obliqua). Inevitably, the analysis involves major consideration of the Roman values which pervade the work. All speeches, thoughts and actions of Aeneas and Turnus are assessed in terms of pietas, impietas, furor, virtus, ratio, clementia, humanitas (etc.). It is shown that individual concepts (such as pietas and impietas) are reflected in Vergil's direct and indirect methods of characterisation. The workings of fate and their relevance to the pietas concept are discussed throughout.

Religion and narrative in the "Metamorphoses" of Apuleius

In this thesis I explore the narratological paradigm of conversion and its usefulness in interpreting the Metamorphoses of Apuleius. I believe that this paradigm is not useful in exploring the novel. However, a closely related paradigm - which I call a "narrative of metamorphosis" - can in fact help us interpret the novel and make sense of the final book of the novel known as the Isis book, which has generated much scholarly debate.

Reconsidering the relationship between early Gothic literature and the Greek classics: the cases of William Beckford and Matthew G. Lewis

The view that Gothic literature emerged as a reaction against the prominence of the Greek classics, and that, as a result, it bears no trace of their influence, is a commonplace in Gothic studies. This thesis re-examines this view, arguing that the Gothic and the Classical were not in opposition to one another, and that Greek tragic poetry and myth should be counted among the literary sources that inspired early Gothic writers. The discussion is organised in three parts. Part I focuses on evidence which suggests that the Gothic and the Hellenic were closely associated in the minds of several British literati both on a political and aesthetic level. As is shown, the coincidence of the Hellenic with the Gothic revival in the second half of the eighteenth century inspired them not only to trace common ground between the Greek and Gothic traditions, but also to look at Greek tragic poetry and myth through Gothic eyes, bringing to light an unruly, ‘Dionysian’ world that suited their taste. The particulars of this coincidence, which has not thus far been discussed in Gothic studies, as well as evidence which suggests that several early Gothic writers were influenced by Greek tragedy and myth, open up new avenues for research on the thematic and aesthetic heterogeneity of early Gothic literature. Parts II and III set out to explore this new ground and to support the main argument of this thesis by examining the influence of Greek tragic poetry and myth on the works of two early Gothic novelists and, in many ways, shapers of the genre, William Beckford and Matthew Gregory Lewis. Part II focuses on William Beckford’s Vathek and its indebtedness to Euripides’s Bacchae, and Part III on Matthew Gregory Lewis’s The Monk and its indebtedness to Sophocles’s Oedipus Tyrannus. As is discussed, Beckford and Lewis participated actively in both the Gothic and Hellenic revivals, producing highly imaginative works that blended material from the British and Greek literary traditions.

The subjunctive mood in Late Middle English adverbial clauses: the interaction of form and function

This thesis focuses on the history of the inflexional subjunctive and its functional substitutes in Late Middle English. To explore why and how the inflexional subjunctive declined in the history of English language, I analysed 2653 examples of three adverbial clauses introduced by if (1882 examples), though (305 examples) and lest (466 examples). Using a corpus-based approach, this thesis argues that linguistic change in subjunctive constructions did not happen suddenly but rather gradually, and the way it changed was varied , and that different constructions changed at different speeds in different environments. It is well known that the inflexional subjunctive declined in the history of English, mainly because of inflexional loss. Strangely however this topic has been comparatively neglected in the scholarly literature, especially with regard to the Middle English period, probably due to the limitations of data and also because study of this development requires very cumbersome textual research. This thesis has derived and analysed the data from three large corpora in the public domain: the Middle English Grammar Corpus (MEG-C for short), the Innsbruck Computer Archive of Machine-Readable English Texts (ICAMET for short), and some selected texts from The Corpus of Middle English Prose and Verse, part of the Middle English Compendium that also includes the Middle English Dictionary. The data were analysed from three perspectives: 1) clausal type, 2) dialect, and 3) textual genre. The basic methodology for the research was to analyse the examples one by one, with special attention being paid to the peculiarities of each text. In addition, this thesis draw on some complementary – indeed overlapping -- linguistic theories for further discussion: 1) Biber’s multi-dimensional theory, 2) Ogura and Wang’s (1994) S-curve or ‘diffusion’ theory, 3) Kretzchmar’s (2009) linguistics of speech, and 4) Halliday’s (1987) notion of language as a dynamic open system. To summarise the outcomes of this thesis: 1) On variation between clausal types, it was shown that the distributional tendencies of verb types (sub, ind, mod) are different between the three adverbial clauses under consideration. 2) On variation between dialects, it has been shown that the northern area, i.e. the so-called Great Scandinavian Belt, displays an especially high comparative ratio of the inflexional subjunctive construction compared to the other areas. This thesis suggests that this result was caused by the influence of Norse, relating the finding to the argument of Samuels (1989) that the present tense -es ending in the northern dialect was introduced by the influence of the Scandinavians. 3) On variation between genres, those labelled Science, Documents and Religion display relatively high ratio of the inflexional subjunctive, while Letter, Romance and History show relatively low ratio of the inflexional subjunctive. This results are explained by Biber’s multi-dimensional theory, which shows that the inflexional subjunctive can be related to the factors ‘informational’, ‘non-narrative’, ‘persuasive’ and ‘abstract’. 4) Lastly, on the inflexional subjunctive in Late Middle English, this thesis concludes that 1) the change did not happen suddenly but gradually, and 2) the way language changes varies. Thus the inflexional subjunctive did not disappear suddenly from England, and there was a time lag among the clausal types, dialects and genres, which can be related to Ogura and Wang’s S-curve (“diffusion”) theory and Kretzchmars’s view of “linguistic continuum”. This thesis has shown that the issues with regard to the inflexional subjunctive are quite complex, so that research in this area requires not only textual analysis but also theoretical analysis, considering both intra- and extra- linguistic factors.

Gestural communication of music structure during solo classical piano performance

The production and perception of music is a multimodal activity involving auditory, visual and conceptual processing, integrating these with prior knowledge and environmental experience. Musicians utilise expressive physical nuances to highlight salient features of the score. The question arises within the literature as to whether performers’ non-technical, non-sound-producing movements may be communicatively meaningful and convey important structural information to audience members and co-performers. In the light of previous performance research (Vines et al., 2006, Wanderley, 2002, Davidson, 1993), and considering findings within co-speech gestural research and auditory and audio-visual neuroscience, this thesis examines the nature of those movements not directly necessary for the production of sound, and their particular influence on audience perception. Within the current research 3D performance analysis is conducted using the Vicon 12- camera system and Nexus data-processing software. Performance gestures are identified as repeated patterns of motion relating to music structure, which not only express phrasing and structural hierarchy but are consistently and accurately interpreted as such by a perceiving audience. Gestural characteristics are analysed across performers and performance style using two Chopin preludes selected for their diverse yet comparable structures (Opus 28:7 and 6). Effects on perceptual judgements of presentation modes (visual-only, auditory-only, audiovisual, full- and point-light) and viewing conditions are explored. This thesis argues that while performance style is highly idiosyncratic, piano performers reliably generate structural gestures through repeated patterns of upper-body movement. The shapes and locations of phrasing motions are identified particular to the sample of performers investigated. Findings demonstrate that despite the personalised nature of the gestures, performers use increased velocity of movements to emphasise musical structure and that observers accurately and consistently locate phrasing junctures where these patterns and variation in motion magnitude, shape and velocity occur. By viewing performance motions in polar (spherical) rather than cartesian coordinate space it is possible to get mathematically closer to the movement generated by each of the nine performers, revealing distinct patterns of motion relating to phrasing structures, regardless of intended performance style. These patterns are highly individualised both to each performer and performed piece. Instantaneous velocity analysis indicates a right-directed bias of performance motion variation at salient structural features within individual performances. Perceptual analyses demonstrate that audience members are able to accurately and effectively detect phrasing structure from performance motion alone. This ability persists even for degraded point-light performances, where all extraneous environmental information has been removed. The relative contributions of audio, visual and audiovisual judgements demonstrate that the visual component of a performance does positively impact on the over- all accuracy of phrasing judgements, indicating that receivers are most effective in their recognition of structural segmentations when they can both see and hear a performance. Observers appear to make use of a rapid online judgement heuristics, adjusting response processes quickly to adapt and perform accurately across multiple modes of presentation and performance style. In line with existent theories within the literature, it is proposed that this processing ability may be related to cognitive and perceptual interpretation of syntax within gestural communication during social interaction and speech. Findings of this research may have future impact on performance pedagogy, computational analysis and performance research, as well as potentially influencing future investigations of the cognitive aspects of musical and gestural understanding.

A III-V channel field effect transistor for non-classical CMOS: process optimisation for improved gate stack function

This thesis describes a collection of studies into the electrical response of a III-V MOS stack comprising metal/GaGdO/GaAs layers as a function of fabrication process variables and the findings of those studies. As a result of this work, areas of improvement in the gate process module of a III-V heterostructure MOSFET were identified. Compared to traditional bulk silicon MOSFET design, one featuring a III-V channel heterostructure with a high-dielectric-constant oxide as the gate insulator provides numerous benefits, for example: the insulator can be made thicker for the same capacitance, the operating voltage can be made lower for the same current output, and improved output characteristics can be achieved without reducing the channel length further. It is known that transistors composed of III-V materials are most susceptible to damage induced by radiation and plasma processing. These devices utilise sub-10 nm gate dielectric films, which are prone to contamination, degradation and damage. Therefore, throughout the course of this work, process damage and contamination issues, as well as various techniques to mitigate or prevent those have been investigated through comparative studies of III-V MOS capacitors and transistors comprising various forms of metal gates, various thicknesses of GaGdO dielectric, and a number of GaAs-based semiconductor layer structures. Transistors which were fabricated before this work commenced, showed problems with threshold voltage control. Specifically, MOSFETs designed for normally-off (VTH > 0) operation exhibited below-zero threshold voltages. With the results obtained during this work, it was possible to gain an understanding of why the transistor threshold voltage shifts as the gate length decreases and of what pulls the threshold voltage downwards preventing normally-off device operation. Two main culprits for the negative VTH shift were found. The first was radiation damage induced by the gate metal deposition process, which can be prevented by slowing down the deposition rate. The second was the layer of gold added on top of platinum in the gate metal stack which reduces the effective work function of the whole gate due to its electronegativity properties. Since the device was designed for a platinum-only gate, this could explain the below zero VTH. This could be prevented either by using a platinum-only gate, or by matching the layer structure design and the actual gate metal used for the future devices. Post-metallisation thermal anneal was shown to mitigate both these effects. However, if post-metallisation annealing is used, care should be taken to ensure it is performed before the ohmic contacts are formed as the thermal treatment was shown to degrade the source/drain contacts. In addition, the programme of studies this thesis describes, also found that if the gate contact is deposited before the source/drain contacts, it causes a shift in threshold voltage towards negative values as the gate length decreases, because the ohmic contact anneal process affects the properties of the underlying material differently depending on whether it is covered with the gate metal or not. In terms of surface contamination; this work found that it causes device-to-device parameter variation, and a plasma clean is therefore essential. This work also demonstrated that the parasitic capacitances in the system, namely the contact periphery dependent gate-ohmic capacitance, plays a significant role in the total gate capacitance. This is true to such an extent that reducing the distance between the gate and the source/drain ohmic contacts in the device would help with shifting the threshold voltages closely towards the designed values. The findings made available by the collection of experiments performed for this work have two major applications. Firstly, these findings provide useful data in the study of the possible phenomena taking place inside the metal/GaGdO/GaAs layers and interfaces as the result of chemical processes applied to it. In addition, these findings allow recommendations as to how to best approach fabrication of devices utilising these layers.
