Design of a system to support policy formulation for sustainable biofuel production

The increased demand for biofuels is expected to put additional strain on the available agricultural resources while at the same time causing environmental degradation. Hence, new energy policies need to be formulated and implemented in order to meet global energy needs while reducing the impact of biofuels farming and production.
This research focuses on proving a decision support system which can aid the formulation of policies for the sustainable biofuel production. The system seeks to address policy formulation that requires reconciliation of the qualitative aspects of decision making (such as stakeholder’s viewpoints) with quantitative data, which often may be imprecise. To allow this, based on: Fuzzy logic and Multi Criteria Decision Making (MCDM) in the form of Analytical Hierarchy Process (AHP). Using these concepts, three software functionalities, “Options vs. Fuzzy Criteria Matrix”, “Analytical Hierarchy Process” and “Fuzzy AHP” were developed. These were added within the framework of pre-existing base software, Compendium (developed by the Open University, UK).
A number of case study based models have been investigated using the software. These models made use of data from the Philippines and India in order to pinpoint suitable land and crop options for these countries. The models based on AHP and Fuzzy AHP were very successful in identifying suitable crop options for India by capturing both the stakeholder viewpoints and quantitative data. The software functionalities are very effective in scenario planning and selection of policies that would be beneficial in achieving a desired future scenario. The models further revealed that the newly developed software correctly identified many of the important issues in a consistent manner.

The properties of nitrogen in silicon

The behaviour of nitrogen in silicon is investigated using the dislocation unlocking technique. Specimens containing well-ordered arrays of dislocations are isothermally annealed for a controlled duration, during which nitrogen segregates to and pins the dislocations. The stress required to unlock the dislocations is then measured by three-point bending at elevated temperature. By analysing the dependence of this unlocking stress on anneal duration and temperature, information about nitrogen's transport and interaction with dislocations can be deduced. Experiments are performed at anneal temperatures of 500 - 1050C using float-zone silicon with [N] = 2x10^15 cm^-3. The results are analysed to give an expression for nitrogen's effective diffusivity of D = 173,000 exp(-3.24eV/kT)cm^2 s^-1 in the 500 - 750C range, showing for the first time that nitrogen transport at low temperatures behaves in the same way as measured at higher temperatures by other groups using secondary ion mass spectrometry. If analysed in terms of monomer-dimer dissociative transport, the results give a nitrogen monomer diffusivity of D_1 = 28 exp(-(1.1 to 1.4 eV)/kT) cm^2 s^-1, which is similar to that found by another analysis in the literature. The measurements also show that nitrogen's dislocation locking strength measured at 550C is dependent on anneal temperature, peaking at 600 - 700C and falling towards zero above 1000C. The dislocation unlocking technique itself is also investigated and characterized. It is found that the measured unlocking stress is dependent on the three-point bend duration, falling with increasing duration. Analysis of these results in terms of the theory of release of dislocations from pinning points indicates that nitrogen dislocation locking is likely to be by an atomic species. This effect also has implications for the results of previous nitrogen dislocation unlocking experiments, and the technique has been modified so that a standardised set of conditions is used for every test. Other measurements show that nitrogen's dislocation locking effect is lessened by the presence of transition metal contamination, and that dislocation velocity in silicon may be affected by the nitrogen present in the material. A modified dislocation unlocking technique is developed to measure dislocation locking from near-surface ion-implanted impurities. Results from heavily N-implanted silicon show that nitrogen implantation can provide additional dislocation locking strength to that already given by the oxygen in the material. The scale of the dislocation locking effect in these experiments may provide evidence that nitrogen's effective diffusivity is reduced at high concentrations, indicating that nitrogen transport may be by a dissociative mechanism.

Liberalism and Marxism in the work of George Orwell

Orwell often treats liberal and radical figures sympathetically and explores his own political position through them. He discriminates between types of liberalism and strongly prefers nineteenth-century liberalism and radicalism to contemporary liberalism. His patriotism, and its distinction from nationalism, are influenced by G.K. Chesterton and by the 'Little England' section of the late nineteenth-century Liberal Party. Many of Orwell's other values, freedom of expression, privacy, and individual autonomy, are part of liberalism. He attacks Marxist forms of socialism which threaten liberal values, and becomes committed to socialism where it promises to protect or fulfil them, although such a form of socialism remains only a possibility. He is best described as a liberal committed to socialism.
Orwell was dissatisfied with the exclusion of historical considerations from most contemporary literary criticism. Marxism was an exception to this. He is influenced by Marxist criticism in his treatment of proletarian literature, and in his critical method of analysing a writer's work in terms of its political tendency and the writer's position in society. His knowledge of passages of Marx's work itself can be traced to The Adelphi. Orwell argues that the writer must be a liberal, and that prose literature is associated with liberalism, yet also admits the Marxist case that liberalism is a product of capitalism. He then doubts whether the culture of liberalism will continue to exist if capitalism is replaced by socialism, and finds it definitely incompatible with the growth of totalitarianism. An uneasy resolution of these dilemmas is reached in the distinction between a man as a writer and as a citizen, the preservation of the writer's liberal mind in a separate compartment from his activity as a man in an increasingly non-liberal society.
The witness-narrator of Orwell's reportage of the 1930s can be compared to the autonomous self preferred by liberalism. These works were not directly influenced by the contemporary documentary movement. Orwell's tendency to appeal to common sense and to argue from observation and experience can be connected with liberalism, as can his view of language as an instrument, and the validation of personal identity by sensation and memory in his work. The distance of the observing subject of his reportage from the observed person can disrupt attempts at empathy and run counter to his expressed socialism.

The statuettes and amulets of Thonis-Heracleion

This study catalogues and analyses 329 statuettes and amulets from Thonis- Heracleion, a sunken city off the coast of Egypt that flourished between the 7th and 2nd centuries BC. This is the first study of votive statuettes and amulets from the Late and Ptolemaic Periods that presents a comprehensive corpus from a single site, complete with detailed catalogue entries and photographs. Although some of the most exceptional pieces were previously published in an exhibition catalogue, the majority are unpublished and it is the first time they have been studied and viewed as a whole.
The material includes not only Egyptian-style bronzes, which are typical dedications of this period, but also a range of other materials including lead, terracotta, faience, and limestone. Some figures are represented in foreign style and attest to a small hellenized community at the site. By viewing multiple categories of votive material laterally and in context, important conclusions about cultural interactions and cult practice at Thonis-Heracleion come to light.
Chapter One details the find context of the statuettes and amulets, followed by a discussion of their types and the cults to which they attest in Chapter 2. Chapter 3 outlines the objects’ primary functions and demonstrates the ways that lead and bronze were utilised differently. Chapter 4 focuses on bronze and lead production methods, particularly methods of replicable production that are indicative of technological exchange with other Mediterranean cultures. Finally, in Chapter 5, I look at how the votives reflect the cultural community at Thonis-Heracleion, and how they compare to others at sites throughout Egypt. Each chapter highlights how the archaeological context informs us about cultural interactions between Egyptians and Greeks and about the dynamics of cult practice at a Delta site in the Late and Ptolemaic Periods.

The Middle Eastern novel in English: literary transnationalism after orientalism

This thesis focuses on the production, circulation, and reception of contemporary Middle Eastern literatures in Britain and the United States. I'm particularly interested in the novel form, and in assessing how both translated Middle Eastern novels and anglophone novels by migrant writers engage with dominant Anglo-American discourses of politics, gender, and religion in the region. In negotiation with Edward Said's Orientalism, I develop a materialist postcolonial critical model to analyse how such discourses undergird publishing and marketing strategies towards novels by Ibrahim Nasrallah, Hisham Matar, Yasmin Crowther, Orhan Pamuk, and others. I argue that as Middle Eastern novels travel, whether via translation or authorial acts of migration, across cultures and languages, they are reshaped according to dominant audience expectations. But, I continue, they also retain traces of their source cultures which must be brought to the surface in critical readings. Drawing on the work of David Damrosch, Pascale Casanova, Franco Moretti, and Aamir Mufti, I thus develop a reading practice, what I call 'post-Orientalist comparatism', that allows me to read past the domesticating strategies framing these novels and to newly reveal their more local, thus potentially transgressive, takes on Middle Eastern socio-political issues. I cumulatively suggest that Middle Eastern novels in English formally embody a dialectic of 'East' and 'West', of the local and the global, thus have important implications for our understanding of the English and world novel traditions.
I conceive of my thesis as a dual intervention into the fields of postcolonial studies and world literature. I am primarily concerned to reorient postcolonial theory around questions of Middle Eastern literary and cultural production, areas that have been traditionally neglected due to an entrenched, but unsustainable, anglophone bias. To do so, I turn to the work of Edward Said, and rethink the foundational problematic of Orientalism with an eye towards political, material, and cultural developments since 1978, the year in which Orientalism was first published, and towards the unique transnational positionality of the genre of the Middle Eastern novel in English. I also turn to theorists of world literature such as David Damrosch in order to develop a reading practice thoroughly attentive to issues of circulation, but, along the lines set out by Aamir Mufti, seek to interrogate their work for its occlusions of the impact of orientalist discourse in the historical development of the category of 'World Literature'. My thesis thus not only draws on postcolonial and world literary theory to analyse its object, the Middle Eastern novel in English, but also demonstrates how proper attention to this object necessitates a theoretical recalibration of these fields.

The dynamics of innovation contests using firm-hosted communities

Firms pursuing an open innovation strategy have increasingly turned to individuals as sources of new ideas. Two main approaches are often highlighted. First, firms can use online innovation contests, where individuals submit ideas in competition for a prize. Second, firms can use firm-hosted online communities, drawing from collaborative efforts of individuals with more intrinsic motivations to participate. A central challenge in both cases is that firms often struggle to sustain participation and effort of participants on an on-going basis. A third hybrid approach, where firms establish community-based innovation contests, has been largely ignored by research, but seems to help firms to engage participants on an on-going basis. This study focuses on community-based innovation contests to understand how firms engage communities to participate in contest over time. I conducted fieldwork at two firms that have successfully run them for many years, Chicago-based T-Shirt firm Threadless and Phoenix-based automotive firm Local Motors. Over ninety interviews with firm employees and community members, over six months of on-site observation at the two firms’ headquarters as well as internal documents and blog data have been collected and analysed. Based on this data the core of the thesis consists of three empirical chapters that examine how firms are able to engage the communities to participate in their contests on a regular basis. First, it shows that the addition of a community to contests increases contestants’ opportunities to learn. In experiential learning, contests provide experience whereas the community provides room for reflection and learning. These learning opportunities motivate contestants to come back and create contest entries on an on-going basis. Secondly, taking a social identity perspective, the research shows how the firms are able to engage the community members continuously by creating a joint firm-community identity. Lastly, it explains how these firms are able to influence community members’ perception of the tasks they are doing through the contest design. Firms are able to turn activities that have been traditionally regarded as work into a recreational activity.

Sacred polychoral music in Rome, 1575-1621

The object of this thesis is to lay open a repertory of music which has long been ignored, the music for two and more choirs composed by Roman composers of the generation of Palestrina and his immediate successors. Polychoral music is taken to mean music in which two or more independent and consistent groups of voices take part, singing separately and together; the parts should remain independent in tuttl sections, with the possible exception of the bass parts. By this definition, the first real polychoral music to be published in Rome was that by Giovanni P. da Palestrina in his Motettorum liber secundus of 1575. This is taken as the starting point for this study. Music which might have influenced Roman composers is examined, as well as eight-voice music by Roman composers which is not polychoral according to the above criteria. The development of polychoral music in the city is then traced through the reigns of the various popes from Gregory XIII to Paul V, whose death in 1621 is taken as a convenient place to end the study. Particular emphasis is laid on structural and textural aspects and the way these were adapted by successive composers. The ground for the Roman concerts to style was laid in the early experiments by composers such as Giovanni Animuccia, Palestrina and Tomas Luis de Victoria; this is traced through what is termed the 'fragmented' style of the last two decades of the sixteenth century to the full flowering of the large-scale concerts to motet after 1605.
The music is studied in the context of the institutions for which it was written. The archives of these Institutions have been researched for information on performance practice, which is presented here. The broader cultural, social and religious background which spawned the idiom is also examined and polychoral music related both to the new propagandist attitude of church leaders from Gregory XIII onwards, and to a general expansion in musical activity in the city of Rome through the period under investigation.
The various printed and manuscript sources for this music have been researched and the resulting catalogue of pieces by fifty or so composers who worked in the city is presented. A more detailed examination is carried out of the primary manuscript sources, from which valuable information on various aspects of the music can be obtained.
Worker responses to work reorganisation in a deep-level gold mining workplace: perspectives from the rock-face

In the early 1990s, South Africa’s re-entry into the competitive global marketplace and the first non-racial elections brought significant changes to an industry previously plagued by the racialisation of the labour process. South Africa’s post-apartheid work order led to the restructuring of the gold mining workplace, with a greatly increased emphasis on efficiency, productivity and equity. This period saw a number of gold mines reorganising work through new forms of working practices aimed at creating new kinds of workers who could identify with the goals of the company by expending rather than withdrawing effort at the point of production. There was a shift in the attitude of worker responses to managerial practices, from coercion to consent in the day-to-day running of the production process.
This thesis examines worker responses to the reorganisation of work and their impact on worker and workplace productivity in a deep-level gold mine. At the core of this thesis are the perceptions, views, experiences and reactions displayed by underground work teams to management initiatives. The thesis highlights the significance of worker agency in managerially defined work structures – the capacity of underground gold miners to reshape and adapt management strategies in ways that make sense and enable them to maintain control over production and the effort-bargain.
The findings presented in this thesis, particularly the gold miners’ informal or coping strategy of making a plan (planisa), reveal that underground work teams are not merely passive or docile reactors to management initiatives. They find opportunity to manipulate (and where necessary, avoid) new forms of management control in a variety of innovative ways that enable them to reassert their power and autonomy over their working day. Underground gold miners are not simply appendages to nor alienated beings in the production process but are able to take control of the production process, independent of management prescriptions, in ways which may embody resistance, consent or a subtle combination of the two. The thesis calls attention to workers’ subjective orientation, agency and resilience to new work structures – not just as recipients but also as shapers of such new work structures within the politics, limits and contradictions of capitalist production systems.

Recalibrating ancient mythology for contemporary performance: the Mises en scène of the Mahabharata by Peter Brook and Les Atrides by Ariane Mnouchkine

There is consensus in academic circles that the directors Peter Brook and Ariane Mnouchkine have similar approaches to theatre practice and occupy the same position in the landscape of theatre production in France. Yet there have not been any in-depth studies that unpack the similarities and differences between the two practitioners. Considering their stature on the national French and international stages, such a gap of scholarship needed to be filled. By examining the specificities of their practices via the analysis of their two most emblematic productions, the Mahabharata and Les Atrides, this thesis hopes to provide an appraisal of their practices at a time when they are moving away from theatre. More specifically, this thesis looks at how the two directors transferred ancient archetypal and mythological narratives to the contemporary French stage. It considers how they used successful, parallel methodologies to adapt and render present an Ancient Sanskrit epic on the one hand (Brook), and Ancient Greek drama on the other (Mnouchkine). I uncover in their work the matrix for adaptation, located in the discourse of storytelling and in the post-Brechtian concept of estrangement, that I label ‘décalage’. Moreover, the thesis hopes to provide an appraisal of the supremacy of directors on the French stage in the nineteen eighties and advocates for the cultural necessity of theatre as an art form, at a time of crisis in France.

Magnetic monopoles and hyperbolic three-manifolds

Let M = H3/andGamma; be a complete , non-compact , oriented geometrically finite hyperbolic 3-manifold without cusps. By constructing a conformal compactification of M x S1 we functorially associate to M an oriented , conformally flat , compact 4-manifold X (without boundary) with an S1-action. X determines M as a hyperbolic manifold.
Using our functor and the differential geometry of conformally flat 4-manifolds we prove that any andGamma; as above with a limit set of Hausdorff dimension andle;1 is Schottky , Fuchsian or extended Fuchsian. Furthermore , the Hodge theory for H2 (X;and#8477;) carries over to H1(M,anddelta;M;and#8477;) and H2(M;and#8477;) which correspond to the spaces of harmonic L2-forms of degree 1 and 2 on M. Comparison of lattices through the Hodge star gives an invariant h(M) andisin; GL(H2(M;and#8477;)/GL(H2(M;and#8484;)) of the hyperbolic structure.
Secondly we pay attention to magnetic monopoles on M which correspond to S1invariant solutions of the anti-self-duality equations on X. The basic result is that we associate to M an infinite collection of moduli spaces of monopoles , labelled by boundary conditions. We prove that the moduli spaces are not empty (under reasonable conditions), compute their dimension , prove orientability , the existence of a compactification and smoothness for generic S1-invariant conformal structures on X. For these results one doesn't need a hyperbolic structure on M , the existence of a conformal compactification X suffices.
A twistor description for monopoles on a hyperbolic M can be given through the twistor space of X , and monopoles turn out to correspond to invariant holomorphic bundles on twistor space. We analyse these bundles. Explicit formulas for monopoles can be found on handlebodies M , and for M = surface x and#8477; we describe the moduli spaces in some detail.
