The object of this dissertation is to record and analyze the foreign policy of the Sultanate of Oman from the early twentieth century until 2004. It challenges the central assumption of the contemporary scholarship on the subject that Muscat's modern foreign policy begins in 1970. It is often presumed that the pre-1970 era does not merit a thorough investigation to understand Muscat's modus operandi today. This study argues that for a comprehensive understanding of Muscat's foreign policy since 1970, the frontier of the historical analysis of Oman's regional and international involvement should be pushed back to the 1930's, when the young Sultan Said assumed power over the country divided by the "Treaty" or the "Agreement" of Sib. Indeed, the thrust of this research lies at once in repudiating the conventional wisdom regarding both the persona of Sultan Said and the customary political/historical narrative of Said's reign. The critical analysis of this period is utilized to rebut the pervasive and largely inaccurate historical narrative of the events prior to 1970, to recount an original interpretation of the period, and to use the narrative as a preamble for subsequent foreign policy directions and initiatives. Furthermore, this dissertation covers the gaps in the literature resulting from the absence of any materials that either record or analyze Muscat's foreign policy from 1996 until 2004. In addition, his study provides new information and a fresh analysis of the international relations of the region, including great power rivalry, especially the competition between the United States and Great Britain, and the attitudes of major regional actors, such as Iran, Saudi Arabia, and Iraq. ^ The use of a thorough historical inquiry is vital to support the central claim of this dissertation; therefore, a large section of this dissertation is based almost exclusively on archival materials collected from the British Public Records Office, the University of Oxford and the Library of Congress. This project represents the most comprehensive use of archival materials on the subject matter to date. ^

Secrecy is fundamental to computer security, but real systems often cannot avoid leaking some secret information. For this reason, the past decade has seen growing interest in quantitative theories of information flow that allow us to quantify the information being leaked. Within these theories, the system is modeled as an information-theoretic channel that specifies the probability of each output, given each input. Given a prior distribution on those inputs, entropy-like measures quantify the amount of information leakage caused by the channel. ^ This thesis presents new results in the theory of min-entropy leakage. First, we study the perspective of secrecy as a resource that is gradually consumed by a system. We explore this intuition through various models of min-entropy consumption. Next, we consider several composition operators that allow smaller systems to be combined into larger systems, and explore the extent to which the leakage of a combined system is constrained by the leakage of its constituents. Most significantly, we prove upper bounds on the leakage of a cascade of two channels, where the output of the first channel is used as input to the second. In addition, we show how to decompose a channel into a cascade of channels. ^ We also establish fundamental new results about the recently-proposed g-leakage family of measures. These results further highlight the significance of channel cascading. We prove that whenever channel A is composition refined by channel B, that is, whenever A is the cascade of B and R for some channel R, the leakage of A never exceeds that of B, regardless of the prior distribution or leakage measure (Shannon leakage, guessing entropy leakage, min-entropy leakage, or g-leakage). Moreover, we show that composition refinement is a partial order if we quotient away channel structure that is redundant with respect to leakage alone. These results are strengthened by the proof that composition refinement is the only way for one channel to never leak more than another with respect to g-leakage. Therefore, composition refinement robustly answers the question of when a channel is always at least as secure as another from a leakage point of view.^

Information processing in the human brain has always been considered as a source of inspiration in Artificial Intelligence; in particular, it has led researchers to develop different tools such as artificial neural networks. Recent findings in Neurophysiology provide evidence that not only neurons but also isolated and networks of astrocytes are responsible for processing information in the human brain. Artificial neural net- works (ANNs) model neuron-neuron communications. Artificial neuron-glia networks (ANGN), in addition to neuron-neuron communications, model neuron-astrocyte con- nections. In continuation of the research on ANGNs, first we propose, and evaluate a model of adaptive neuro fuzzy inference systems augmented with artificial astrocytes. Then, we propose a model of ANGNs that captures the communications of astrocytes in the brain; in this model, a network of artificial astrocytes are implemented on top of a typical neural network. The results of the implementation of both networks show that on certain combinations of parameter values specifying astrocytes and their con- nections, the new networks outperform typical neural networks. This research opens a range of possibilities for future work on designing more powerful architectures of artificial neural networks that are based on more realistic models of the human brain.

To be at home means to be embedded in a dense pattern of relationships to people and place which gives rise to an inherently meaningful experience of the world. This order is neither abstract nor imposed from without, but crystallises from the shared experience of people inhabiting a concrete location. Home involves the localisation of meaning in a concrete setting and in the activities of everyday life, and this embodies an ongoing process of ‘cosmicisation’ which is vital for both social life and individual well-being. Home is not a fixed structure, static and frozen, which shuts out the external world; it is a dynamic centre which draws in experience and gives it meaning. It is a constellation of significance rather than a singular and unitary essence. It is produced by localising processes, which work to concentrate and stabilise value around a secure centre. The elaboration of seven interlinked localising processes forms the core of the thesis: The cultivation of place The accumulation of collective memory The crystallisation of life-ways and their evolution into tradition The generation of mutuality of being through sharing in fundamental biological processes which generate and preserve life Social circles of gift exchange and recognition which reinforce this mutuality of being The elaboration of symbolic boundaries The counterparts of localising processes are globalising ones. These involve the dismantling of the taken-for-granted relationships of everyday life and their reconstitution within spatially extended networks, governed by rationalised institutions, within separate spheres of economic production, commercial transactions, political administration and cultural exchange. The global market, the public arena, technological development and the bureaucratic state are all solvents of localised associations, which result in the dissipation and relativisation of value. However globalising processes never entirely displace localising ones. Even today, localising processes shape those areas of our lives which anchor our identities and provide a sense of meaning: the everyday interactions of home, family, community and intimate circles of friendship.

Skepticism regarding witchcraft, characteristic (but not exclusive) of the Spanish lands, corresponds with a particular view of evil’s etiology. Whereas paradigmatic texts of radical demonology, as the Malleus Maleficarum, gave a conclusive step towards the demonization of natural evil (as they put the blame on the devil and the witches for calamities and plagues), texts of Castilian origin, as Alonso de Espina’s Fortalitium fidei, embraced the traditional position: they considered the devil as a promoter of moral evil in the world, meanwhile natural evil is seen as a result of the wrath of God for the sins of His people –particularly, the sin of Christian princes. I argue that the distinction between these two ways of thinking the causality of the world’s misfortunes can be read in political terms.

Educational systems worldwide are facing an enormous shift as a result of sociocultural, political, economic, and technological changes. The technologies and practices that have developed over the last decade have been heralded as opportunities to transform both online and traditional education systems. While proponents of these new ideas often postulate that they have the potential to address the educational problems facing both students and institutions and that they could provide an opportunity to rethink the ways that education is organized and enacted, there is little evidence of emerging technologies and practices in use in online education. Because researchers and practitioners interested in these possibilities often reside in various disciplines and academic departments the sharing and dissemination of their work across often rigid boundaries is a formidable task. Contributors to Emergence and Innovation in Digital Learning include individuals who are shaping the future of online learning with their innovative applications and investigations on the impact of issues such as openness, analytics, MOOCs, and social media. Building on work first published in Emerging Technologies in Distance Education, the contributors to this collection harness the dispersed knowledge in online education to provide a one-stop locale for work on emergent approaches in the field. Their conclusions will influence the adoption and success of these approaches to education and will enable researchers and practitioners to conceptualize, critique, and enhance their understanding of the foundations and applications of new technologies.

Summary: This is a conceptual paper that aims to identify the key perspectives on business model innovation. Understanding the theoretical and conceptual underpinnings of business model innovation is crucial in facilitating organisation in reinventing their business models. Through a comprehensive literature review, three perspectives are identified. Business model innovation is a complex construct. There is no single approach or method in undertaking business model innovation. Successful undertaking of business model innovation depends on a number of factors. Dynamic capabilities and internal capabilities are just two of many important factors.

A fully coupled non-linear effective stress response finite difference (FD) model is built to survey the counter-intuitive recent findings on the reliance of pore water pressure ratio on foundation contact pressure. Two alternative design scenarios for a benchmark problem are explored and contrasted in the light of construction emission rates using the EFFC-DFI methodology. A strain-hardening effective stress plasticity model is adopted to simulate the dynamic loading. A combination of input motions, contact pressure, initial vertical total pressure and distance to foundation centreline are employed, as model variables, to further investigate the control of permanent and variable actions on the residual pore pressure ratio. The model is verified against the Ghosh and Madabhushi high acceleration field test database. The outputs of this work is aimed to improve the current computer-aided seismic foundation design that relies on ground’s packing state and consistency. The results confirm that on seismic excitation of shallow foundations, the likelihood of effective stress loss is greater in deeper depths and across free field. For the benchmark problem, adopting a shallow foundation system instead of piled foundation benefitted in a 75% less emission rate, a marked proportion of which is owed to reduced materials and haulage carbon cost.

This project investigates why people in Chile acquired so much consumer debt in contexts of material prosperity, and asks what the role of inequality and commodification is in this process. The case raises an important challenge to the literature. Insofar as existing accounts assume that the financialization of consumption occurs in contexts marked by wage stagnation and a general deterioration of the middle classes, they engender two contradictory explanations: while political economists argue that people use credit in order to smooth their consumption in the face of market volatility, economists maintain that concentration of wealth at the top pushes middle income consumers to emulate the expenditures of the rich and consume beyond their means. These explanations do not necessarily fit the reality of developing countries. Triangulating in-depth interviews with middle class families, multivariate statistical analysis and secondary literature, the project shows that consumers in Chile use credit to finance “ordinary” forms of consumption that do not aim either at coping with market instability or emulating and signaling status to others. Rather, Chileans use department store credit cards in order to acquire a standard package of “inconspicuous” goods that they feel entitled to have. From this point of view, the systematic indebtedness of consumers originates in a major concern with “rank”, “achievement” and "security" that – following De Botton -- I call “status anxiety”. Status anxiety does not stem from the desire to emulate rich consumers, but from the impossibility of complying with normative expectations about what a middle class family should be (and have) that outweigh wage improvements. The project thus investigates the way in which “status anxiety” is systematically reproduced by means of two broad mechanisms that prompt people to acquire consumer debt. The first mechanism generating debt stems from an increase of real wages and high levels of inequality. It is explained by a general sociological principle known as relative deprivation, which points to the fact that general satisfaction with one´s income, possessions or status, is assessed not in absolute terms such as total income, but in relation with reference groups. In this sense, I explore the mechanisms that operate as catalyzers of relative deprivation, by making explicit social inequalities and distorting the perception of others´ wealth. Despite upward mobility and economic improvement, Chileans share the perception of “falling behind,” which materializes in an “imaginary middle class” against which people compare their status, possessions and economic independence. Finally, I show that the commodification of education, health and pension funds does not directly prompt people to acquire consumer debt, but operate as “income draining” mechanisms that demand higher shares of middle class families’ “discretionary income.” In combination with “relative deprivation,” these “income draining” mechanisms leave families with few options to perform their desired class identities, other than learning how to bring resources from the future into the present with the help of department store credit cards.
