The evolution of two archaic Sicilian poleis

This study attempts to revive T.J. Dunbabin's multi-dimensional approach to the history of Early Iron Age Sicily in The Western Greeks (Oxford 1948). Dunbabin recognised that archaic Sicily had no real history, and that any historical account involved combining the very scant documentary record with the fuller and ever-growing body of archaeological evidence to produce a framework for writing social and economic history. These innovative methods ended with Dunbabin, however: today the field is dominated by scholars impeded artificially by disciplinary boundaries, which discourage the productive combination of historical and archaeological sources, leaving a number of important questions in a sort of academic no man's land. In the introduction an overview of the study of Sicily since Dunbabin is given, and Dunbabin's own weaknesses are explored: Dunbabin modelled Greek colonisation in Sicily on modern British colonisation; such a decision strait-jacketed his image of the past, causing him to draw conclusions unacceptable today. The increase in the quantity of archaeological evidence since Dunbabin means that it is no longer possible to make an in-depth study of the whole of Sicily in a single volume. Consequently, the focus has to be considerably more restricted than Dunbabin's; specific questions need to be selected.
Megara Hyblaia and Selinous offer two particular advantages for studying the evolution of Greek settlement in Sicily: besides being Megarian, both are sufficiently well explored archaeologically to make historical investigation profitable, but they were founded a century apart on different sides of the island, in different environmental and socio-political contexts. The study itself is divided into two main parts, the first focusing on Megara Hyblaia and the second on Selinous; each of these two parts consists of five chapters, in which the same questions are asked of the evidence from the two sites, for comparative purposes. Chapters I and VI explore the background to settlement, with such subjects as the native world encountered by the settlers at the time of colonisation, pre- and proto-colonial activity, and the respective foundations of the colonies examined. Settlement development is the subject of chapters II and VII; the emphasis here is to monitor the successive stages of the physical growth of the colonies, and also to study the size and nature of the settlement itself. Chapters III and VIII deal with demography (particularly population size). The following chapters (IV and IX) use archaeological and written evidence to reconstruct socio-political history. Chapters V and X investigate environment and economy. In the closing chapter, after a review of the conclusions reached, the question of why Selinous evolved so differently from it mother-city is addressed. The thesis ends with brief consideration of the (Megarian) Sicilian contribution to the study of the polis.
Martha Gellhorn

How war is depicted matters vitally to all of us. In the vast literature on war representation, little attention is paid to the fact that where the war recorder1stands crucially affects the portrayal. Should the writer be present on the battle-field, and, if so, where exactly? Should the recording figure be present in the text, and, if so, in what guise? 'Standing' differs from person to person, conflict to conflict, and between genders. Therefore, this thesis focuses on one particular war recorder in one particular war: the American journalist and fiction-writer, Martha Gellhorn (1908-98), in the European Theatre of Operations during World War Two. The fact that Gellhorn was a woman affected how she could and did place herself in relation to battle - but gender, though important, was not the only factor. Her course in and around war was dazzling: hitching rides, stowing away, travelling on dynamite-laden ships through mined waters, flying in ancient planes and deadly fighter jets, driving from battle-field to battle-field, mucking in, standing out. Her trajectory within her prose is equally versatile: she zooms in and out like a camera lens from impassiveness to intense involvement to withdrawal. The thesis is organised along the same spectrum. The first two chapters plot the co- ordinates forming the zero point on the graph of Gellhorn's Second World War writings (earlier American war correspondence, the 1930s' New Reportage, Gellhorn's upbringing and journalistic apprenticeship). Chapter Three then shows her in the guise of self-effacing, emotionally absent recorder. Moving from absence to presence, Chapter Four considers Martha Gellhorn in the field and Chapter Five 'Martha Gellhorn' in the text. Chapter Six describes the shift from presence to participation, before reaching the end of the parabola in Gellhorn's disillusionment in the power of writing to reform and her concerns about women's presence in the war zone. Given that positioning is the central concern, it is important to note the placement of Martha Gellhorn within the thesis itself. She stands as the central, pivotal example of the war recorder, illuminated by various contexts and comparisons with other writers (notably Ernest Hemingway, to whom she was married from 1940 to 1945). As a result of this approach, there are necessarily stretches of the text from which she is absent, as the survey turns to theoretical and comparative discussion. The hope is that this methodology reveals why Gellhorn, in the field and in the text, went where she did.

Fundamental flux enhancement modelling of membrane microfiltration

Membrane filtration is used in a variety of industries, including water treatment and the food industry. Membrane systems include microfiltration and reverse osmosis processes. Membranes used in reverse osmosis are nonporous or pores at 0.2-2 A. This work will focus on mechanical microfiltration. These filtration systems suffer from an accumulation of the rejected material near the membrane surface. This causes additional resistance to the flow through the membrane (flux), resulting in a decline in the performance of the system.
Sparging gas bubbles into the mixture has been shown to improve performance. The flow field promotes the transport of material away from the membrane surface and into the bulk. The goal is to predict the sparging that will achieve the maximum flux. Existing flux prediction models often assume steady shear at the membrane surface but in bubbling regimes the shear stresses are unsteady.
In this thesis a model is developed to calculate the flux based not solely on shear but on the behaviour and resistance of suspended particles in a gas-liquid flow field. The bubble shape and flow field is calculated using computation fluid dynamics (CFD). The flow around a bubble in gap between two parallel flat sheet membranes is investigated. The calculated bubble shape correlates well with the results seen in experiments. The bubble rise velocity with respect to gap width is shown to transition between that expected in the literature for extended flow for large gap widths and that for a two dimensional case for smaller gap widths. The transitional region however, does not behave as may be expected. The rise velocity does not monotonically decrease as the gap width is reduced.
The particle concentration is found by the solution of the convection-diffusion equation, where the convection velocity terms are given by the results of the CFD calculation. The permeate flux is then calculated using a resistance model giving the enhancement due to the bubble. The model is also applied to single phase crossflow. As the shear stresses are steady in this single-phase flow regime, established membrane shear linked mass-transfer coefficient methods can be employed. Good agreement is found between the model and theory.
The flux results obtained when the model is applied to the flow around the bubble show a peak in performance with respect to the gap between the membranes for a given bubble volume. The optimal flux enhancement is found to correlate well with the bubble size compared to the flow area. The results show a bubble width of around 60% of the flow width provides the best flux performance.

Structural and thermogravimetric studies of group I and II borohydrides

This thesis investigates the structure and thermal behaviour of LiBH4, NaBH4, KBH4, LiK(BH4)2, Ca(BH4)2 and Sr(BH4)2. LiK(BH4)2 is the first mixed alkali metal borohydride and was synthesised and characterised during this work. The crystal structures of these borohydrides were studied using variable temperature neutron and synchrotron X-ray diffraction. The synthesis of isotopically enriched samples of 7Li11BD4, Li11BD4, Na11BD4 and K11BD4 allowed high quality neutron diffraction data to be collected. Particular attention was paid to the exact geometry of the borohydride ions which were generally found to be perfect tetrahedra but with orientational disorder. New structures of Ca(BH4)2 were identified and the first crystal structure of Sr(BH4)2 was determined from synchrotron X-ray diffraction data. Solid state 11B NMR and Raman spectroscopy provided further information about the structure of these borohydrides. The thermal behaviour of the borohydrides was investigated using thermogravimetric analysis with mass spectrometry of the decomposition gas products. Hydrogen is the main decomposition gas product from all of these compounds but small amounts of B2H6 and BH3 were also detected during decomposition. Thermogravimetic analyses of Na11BD4 and K11BD4 were completed whilst collecting in-situ neutron diffraction data allowing information about structural changes and mass losses to be combined in order to better understand the decomposition process.

Series interconnects and charge extraction interfaces for hybrid solar cells

This thesis investigates novel hole extraction interfaces and series interconnects for applications in organic photovoltaics, specifically in single junction solid-state dye-sensitized solar cells (DSSCs) and tandem DSSC/polymer bulk heterojunction solar cells. Improvements in hole extraction and device performance by using materials compatible with scalable deposition methods are presented, including tungsten- and molybdenum-disulphide (WS2 and MoS2), and p-type doped spiro-OMeTAD (2,2',7,7'-tetrakis-(N,N-di-p-methoxyphenylamine)9,9'-spirobifluorene) nanoparticle dispersions. WS2 and MoS2 hole extraction layers increase averaged short circuit currents by 20% and 16% respectively, and power conversion efficiencies by 19% and 14% respectively when compared with control devices. Similarly, doped spiro-OMeTAD nano-particle layers improved short circuit current densities by 32% and efficiencies by 9%. Tandem device interconnects using these novel hole extraction formats have been fabricated, but although devices did exhibit rectification, overall performance was poor. Possible reasons for their limited success have been analysed.
Dye-sensitized solar mini-modules are also reported. In order to assure the scalability of DSSC technology, these larger area devices were constructed using doctor blade coating to deposit the hole transporter material. As well as achieving a respectable maximum power conversion efficiency of 2.6%, it has also been shown that the extent to which hole transporter infiltrates the mesoporous photoanode of these devices may be tuned by altering substrate temperature during deposition. It was found that an optimal coating temperature of 70 degrees C produced the best efficiency, with a corresponding pore-filling fraction of 41%.

"Dig for Bloody Victory"

Most people’s perceptions of the Second World War leave little room for static, attritional fighting; instead, free-flowing manoeuvre warfare, such as Blitzkrieg, is seen as the norm. In reality, however, much of the terrain fought over in 1939-45 was unsuitable for such a war and, as a result, bloody attritional battles and trench fighting were common. Thus ordinary infantrymen spent the majority of their time at the front burrowing underground for protection. Although these trenches were never as fixed or elaborate as those on the Western Front a generation earlier, the men who served in Italy, Normandy, Holland and Germany, nonetheless shared an experience remarkably similar to that of their predecessors in Flanders, Picardy, Champagne and Artois. This is an area which has been largely neglected by scholars. While the first war produced a mountain of books on the experience of trench warfare, the same cannot be said of the second war. This thesis will attempt to fill that gap by providing a comprehensive analysis of static warfare in the Second World War from the point of view of British infantry morale. It draws widely on contemporary letters and diaries, psychiatric and medical reports and official documentation – not to mention personal narratives and accounts published after the war – and will attempt to interpret these sources in light of modern research and organise them into a logical framework. Ultimately it is hoped that this will provide fresh insight into a relatively under-researched area of twentieth century history.

Limits of Islamism: ideological articulations of Jamaat-e-Islami in contemporary India and Bangladesh

My doctoral thesis analyses the political ideology of Islamism by taking the case study of a major Islamist organization, namely the Jamaat-e-Islami in contemporary India and Bangladesh. In doing so, I try to understand the similarities and differences of the ideological articulations of Islamism in a Muslim minority context of India and in a Muslim majority context of Bangladesh. The thesis is written from a political theory perspective in general and within the realm of ideology studies in particular. The study analyses how and why the Jamaat is responding to the economic and cultural issues of neoliberal India and Bangladesh. One cannot possibly ignore the neoliberal context within which Islamists are generating markedly new kinds of political articulations with an unprecedented set of political demands, never seen before in the history of Islamist movements. The ideological articulations of Jamaat have been studied by analyzing various primary sources—organisational literature, the party constitution, policy resolutions, press releases, election manifestos and political pamphlets of Jamaat-e-Islami. In addition, this dissertation has also relied on field interviews with the Jamaat leadership in India and Bangladesh. Magazines and internet sources have been also helpful for this study. My thesis analyses Islamist responses to neoliberalism by discussing the contrasting conditions of contemporary India and Bangladesh. In doing so, I conclude that in India, Jamaat is opposed to neoliberalism whereas in Bangladesh, it has a ambiguous character vis-à-vis neoliberalism. However, Islamists in both these countries are opposed to cultural issues like atheism, ‘blasphemous’ views, live-in relationships and homosexuality, which they construe as the products of ‘western cultural globalization’. In this respect, I try to analyse why the Islamists are opposed to ‘western cultural globalization’. Finally, I also explain how Islamism, as a politico-ideological project of populist mobilization is facing a crisis in contemporary India and Bangladesh.

Cell fate mechanisms in colorectal cancer

Colorectal cancer (CRC) arises in part from the dysregulation of cellular proliferation, associated with the canonical Wnt pathway, and differentiation, effected by the Notch signalling network. In this thesis, we develop a mathematical model of ordinary differential equations (ODEs) for the coupled interaction of the Notch and Wnt pathways in cells of the human intestinal epithelium. Our central aim is to understand the role of such crosstalk in the genesis and treatment of CRC.
An embedding of this model in cells of a simulated colonic tissue enables computational exploration of the cell fate response to spatially inhomogeneous growth cues in the healthy intestinal epithelium. We also examine an alternative, rule-based model from the literature, which employs a simple binary approach to pathway activity, in which the Notch and Wnt pathways are constitutively on or off. Comparison of the two models demonstrates the substantial advantages of the equation-based paradigm, through its delivery of stable and robust cell fate patterning, and its versatility for exploring the multiscale consequences of a variety of subcellular phenomena.
Extension of the ODE-based model to include mutant cells facilitates the study of Notch-mediated therapeutic approaches to CRC. We find a marked synergy between the application of γ-secretase inhibitors and Hath1 stabilisers in the treatment of early-stage intestinal polyps. This combined treatment is an efficient means of inducing mitotic arrest in the cell population of the intestinal epithelium through enforced conversion to a secretory phenotype and is highlighted as a viable route for further theoretical, experimental and clinical study.

An LFG approach to Old English constituent order

Old English (OE) differs from Present Day English (PDE) in many ways although the most noticeable is perhaps consituent order. Many generative analyses from van Kemenade (1987) to Pintzuk (1999) have sought to explain Old English word order, but no purely transformational account has successfully explained the data. In this thesis, I show how the multi-projection architecture of Lexical-Functional Grammar (LFG) can explain the data in a way unavailable to transformational accounts. While the thesis treats several different areas of grammar, there are consistent themes that emerge throughout. I will first survey the basic data that an analysis of Old English should seek to explain. This will be the focus of of Chapter 1. From there, I will consider previous analyses of OE including head-first accounts, head-final accounts, the competing grammars account, and Clark’s 2004 OT-LFG analysis in Chapter 3. Chapter 4 will introduce the basics of LFG with specific reference to Old English. The main body of the paper will focus on elements of my own lexical-functional analysis of Old English, which has been developed and tested using XLE (Crouch et al., 1998). Through the interplay of the f-structure and c-structure, LFG improves our understanding of OE syntax. Chapter 5 builds upon Clark (2004) by proposing a novel hierarchical verb cluster. Chapter 6 offers a discourse-based account of OE constituent order within the LFG framework. And Chapter 7 points the way towards an improved formal analysis of word order freezing in LFG. My conclusion offers final thoughts and directions for future research.
Although this project grew out of a desire to analyze Old English systematically and without stipulation, it has largely become an effort to develop and analyze the relationships between the multiple projections available in LFG, specifically the effects of these relationships on the constituent structure. Besides just offering a fascinating laboratory for testing the bonds that hold together various parts of syntactic structure, Old English is an important language to study for its diachronic implications. If we can develop a coherent picture of Old English syntax and understand how and why consitutents get ordered in OE in the way that they do, we are a step closer to understanding how and why the language has changed in the way that it has. For example, it is not insignificant that the verb cluster I propose in Chapter 5 is rare in Middle English and vanishingly rare by Shakespeare’s time. In the space available in this thesis, I will be unable to delve too deeply into these diachronic considerations. But I believe that much of what is presented here is essential to that project and can point to exciting new directions in diachronic syntax and ultimately contribute to a clearer picture of language change. And language change is a powerful window into the way that language works as a whole.

The Limba of Sierra Leone with special reference to their folktales or oral literature

The thesis la an annotated edition of Limba folktales or "oral literature". This is unusual In recent British anthropology in spite of the earlier interest in the subject, mainly because of the reaction against evolutionism, and the more recent structuralist and functionalist approach. Various approaches to folktales and myth are laid aside as irrelevant or unhelpful. The senses in which linguistic, structural and, in particular, sociological approaches are relevant to the present study are discussed, and various criticisms made of the narrowness or misleading implications of the more recent "sociological" attitudes to oral literature in non-literate societies. The present approach is to treat suoh material as having the status of literature ("oral literature"), rather than as being in some way utilitarian, and to relate the stories to their social background, discuss their contents, categories, delivery, and narrators systematically, and discover something of what they mean to those telling and hearing them.
