title: The ‘new’ Addis Ababa: shantytown or global city? An assessment of large-scale inner-city renewal, redevelopment and displacement for the construction of a ‘new’ Addis Ababa

description: The aim of this thesis is to assess large-scale, inner-city renewal, redevelopment, and displacement in Addis Ababa for the construction of a ‘new’ Addis Ababa, while referring to the wider historical, contextual, and the global setting in which this process takes place. This research followed an inductive, qualitative research strategy and used an embedded single-case study research design. Primary data was collected through in-depth, semi-structured interviews, for which thematic-based interview guides were developed; the data was then analysed thematically. The main argument of this thesis is that in Addis Ababa urban renewal and redevelopment have grown in volume and scale transforming into a new form of urban development. The construction of a ‘new’ Addis Ababa as a City-within-a-City on top of the exiting urban fabric is a type of New City development that seeks to re-make and re-model the city alongside Global and World City (GaWC) standards. This research found that the construction of the ‘new’ Addis Ababa is a form of new-built gentrification, which is producing social-economic spatial segregation through a form of social-spatial restructuring at a municipal scale, which can lead to distributional differences and spatial inequality. This research also found, while the construction of the ‘new’ Addis Ababa is still underway (and may always remain partial and incomplete), it is questionable if this urban transformation will ultimately lead to an improved position in global urban hierarchies. The city’s transformation has already had significant exclusionary effects on households displaced for the sake of inner-city renewal and redevelopment. Households without lawful land or tenancy rights are not compensated for their losses when they are displaced. This is a neglect of their basic rights to housing. Even though the transformation of Addis Ababa aims to prevent and reduce illegal settlements, it is instead forcing a specific group of low-income urban dwellers, whose demand is not addressed by the housing market, to migrate and reappear elsewhere in the city as illegal settlers. Households that do receive compensation may on the other hand not be able to afford the relocation associated costs, which puts them at risk for impoverishment. These households are relocated to peri-urban zones through an ex-situ strategy in a dispersed manner, which dismantles their social and economic neighbourhood based inter- and intra-community networks and leads to social and economic losses. The restoration of these social and economic networks post-relocation is hindered by a spatial and lifestyle change imposed on households, which furthermore prohibits them from returning to their old ways of life and hinders their ability to ‘bounce-back’.
title: Isolation and characterization of variants of polyoma transformed BHK 21 cells defective in adhesion to fibronectin
Creators: name: Salama, Nasr M.
Publisher: name: University of Glasgow
Year: 1986

description: In order to investigate the interplay between the cell surface and the cytoskeleton in adhesion, variants of polyoma-transformed BHK 21 cells were isolated with or without N-methyl-N-nitro-N-nitrosoguanidine as a mutagen, which are of very low adhesiveness towards surfaces coated with fibronectin. On culture surface the variants yield loosely attached colonies of very distinctive unspread morphology. Variants retain the ability to cap fluorescent Con A, and are unable to spread on any surface yet tested, including adsorbed serum, Con A, fibronectin, vitronectin or poly-L-lysine. In a flow-chamber adhesion assay, which minimises the contribution of gross spreading to adhesion, the variants are much less adhesive to fibronectin or serum films than the parental cells, but they adhere equally to poly-L-lysine. A high proportion (35%) of cells in a variant population showed spreading ability on a clean tissue culture plastic surface. The proportion of variants spread is less than that of parental cells. Mn at 10-4M did not stimulate these variants to spread 'to full extent, but there was an increase in spreading in response to manganese on tissue culture plastic in absence of serum. An f-actin specific fluorescent probe showed the distribution of f-actin in Py3 cells on a surface coated with fibronectin. Stress fibres appeared very distinct. No stress fibres were observed in the variants in the course of study. f-actin was seen underneath the plasma membrane and at cell-cell contact areas. Proteins retained in detergent insoluble residues of Py3 and variants were studied by various techniques. No differences in protein bands were seen. The alteration in these variants can be explained as follows: 1. There are simultaneous changes in the ability of cell surface to bind fibronectin and in the cytoskeletal control. 2. The putative fibronectin receptor, altered in the variant, is involved in some way in the spreading response on all surfaces.

description: Koopman mode decomposition and tensor component analysis (also known as CANDECOMP/PARAFAC or canonical polyadic decomposition) are two popular approaches of decomposing high dimensional data sets into low dimensional modes that capture the most relevant features and/or dynamics. Despite their similar goal, the two methods are largely used by different scientific communities and formulated in distinct mathematical languages. We examine the two together and show that, under a certain (reasonable) condition on the data, the theoretical decomposition given by tensor component analysis is the \textit{same} as that given by Koopman mode decomposition. This provides a "bridge" with which the two communities should be able to more effectively communicate. When this condition is not met, Koopman mode decomposition still provides a tensor decomposition with an \textit{a priori} computable error, providing an alternative to the non-convex optimization that tensor component analysis requires. Our work provides new possibilities for algorithmic approaches to Koopman mode decomposition and tensor component analysis, provides a new perspective on the success of tensor component analysis, and builds upon a growing body of work showing that dynamical systems, and Koopman operator theory in particular, can be useful for problems that have historically made use of optimization theory.

title: Sylvia Plath - the woman and her time: an intertextual approach
Creators: name: Brennan, Claire Josephine
Publisher: name: University of Glasgow
Year: 1996

description: Criticism of Sylvia Plath's writing has tended to privilege her personal history over the social and historical context that to a large extent constructs the personal. This thesis is concerned with placing the writing of Plath within its social and historical context, and aims to illustrate, through considering the process of the construction of self through society, the extent to which Plath's writing is involved with an era. Recent discussions considering Plath from a feminist perspective have concentrated on the expression of a woman's consciousness which arises from a sexualized, gendered conflict. While these discussions are relevant to this thesis, I argue for a more contextualized view of Plath's writing which insists on reading the conflicts and tensions of the writing as consistent with specific historical and social pressures. As an introduction to considering the way in which a self is constructed in Plath's writing, this thesis briefly considers the way in which Plath has been created by her biographers. This chapter reflects the critical response to Plath's work. The second chapter '"My Emulous Urge": American Women's Magazines' begins to engage with the idea of intertextuality and explores the relationship between Plath's writing and women's magazines. By considering Plath's involvement, both as a reader and as a young publisher, the styling, format and ideology is seen to influence aspects of Plath's writing. Initially prepared to construct a social self through the prescriptions of the magazines, Plath's writing undertakes a process of self construction which struggles with compliance and redefinition. This is considered in relation to the iconography of the female self. The third chapter "The Domestic State: Personal and Political", discusses the domestic context of much of Plath's writing, suggesting the significance of place and era in the consideration of mothering. Parallels are drawn between the isolated, inner worlds of the housewife, and the tensions generated by the American politics of the Cold War. Through figures such as Dr Spock, Ethel Rosenberg and J Edgar Hoover, Plath's writing can be seen to be imbued with fears and strictures of the time. This is further developed to consider the role of hospitalization in Plath's writing, which is seen as part of the social conditioning of women in this era. The final chapter to consider Plath's own awareness of context, 'Waist deep in History', considers the struggle for the articulation of a historical self in relation to historical events of the twentieth century. The impact of the Holocaust is considered in both an American and European context, finally suggesting that a historically sensitive and political voice is evident in Plath's writing. In conclusion, it has seemed important to recognize the contextualisation of Plath by other writers, in particular the generation of American writers who share a past with Plath, but who are unable to discuss the present.
Accidents Involving Vehicles Parked on Shoulders of Limited Access Highways

description: This study was conducted to quantify the extent of the problem of accidents involving vehicles on shoulders of limited access highways. Accident data for a three-year period (1985-1987) were collected along with a survey of vehicles stopped on the shoulder on interstates and parkways.  While the percentage of all accidents on interstates and parkways involving a vehicle on the shoulder is small (1.8 percent), the percentage of fatal accidents involving a vehicle on the shoulder is significant (11.1 percent). The accident data revealed that the majority of shoulder vehicles had stopped for an emergency stop as opposed to a leisure stop with a large number involving an abandoned vehicle. The most common reason for stopping was a mechanical failure. Tractor-trailers were overrepresented in shoulder accidents. An unusually high percentage occurred in the time period of midnight to 6 a.m. The major contributing factors were alcohol involvement and the driver on the mainline falling asleep.  Two types of observational surveys were taken. One survey represented what a driver would observe while driving from one point to another on an interstate or parkway. It indicated that a driver would pass (in his direction of travel) an average of about one vehicle on the shoulder every eight miles on an interstate and every 17 miles on a parkway. The second survey was conducted in a circular route such that almost all stops would be observed. The highest percentage of stops were over one hour in length.

description: It remains an open question as to how long ago the morphology that we see in a present-day galaxy was typically imprinted. Studies of galaxy populations at different redshifts reveal that the balance of morphologies has changed over time, but such snapshots cannot uncover the typical timescales over which individual galaxies undergo morphological transformation, nor which are the progenitors of today's galaxies of different types. However, these studies also show a strong link between morphology and star-formation rate over a large range in redshift, which offers an alternative probe of morphological transformation. We therefore derive the evolution in star-formation rate and stellar mass of a sample of 4342 galaxies in the SDSS-IV MaNGA survey through a stellar population "fossil record" approach, and show that the average evolution of the population shows good agreement with known behaviour from previous studies. Although the correlation between a galaxy's contemporaneous morphology and star-formation rate is strong over a large range of lookback times, we find that a galaxy's present-day morphology only correlates with its relatively recent (~2 Gyr) star-formation history. We therefore find strong evidence that morphological transitions to galaxies' current appearance occurred on timescales as short as a few billion years.

description: Possible variations in the dynamical behaviour of LiYF$_{4}$ due to its several structural changes under pressure are examined by making use of the complementary techniques of quasi-harmonic lattice dynamics and molecular dynamics simulations. The phonon spectra in the entire Brillouin zone together with the respective Gibbs free energies are calculated for the three high-pressure polymorphs of LiYF$_{4}$ (that are stable at T = 0) with a view to better understand their relative stabilities as functions of pressure and temperature. The present work predicts anomalous thermal expansion at low temperatures in phases I and IIa while irreversibilty of phase II $\to$ phase III transition on subsequent pressure release. Molecular dynamics simulations provide qualitative impressions about a temperature-driven second-order transition and also of kinetic effects in the subsequent pressure-driven first-order phase transformation.

In addition to an implicit algebraic form for the general solution, we also give a power series expression for all finite sets of multipole moments. As conjectured by Geroch we prove in the special case of axisymmetry, that there is a static space-time for any given set of multipole moments subject to a (specified) convergence criterion. We also use this method to confirm a conjecture of Hernandez-Pastora and Martin concerning the monopole-quadropole solution.

Control of atomic decay rates via manipulation of reservoir mode frequencies

description: We analyse the problem of a two-level atom interacting with a time-dependent dissipative environment modelled by a bath of reservoir modes. In the model of this paper the principal features of the reservoir structure remain constant in time, but the microscopic structure does not. In the context of an atom in a leaky cavity this corresponds to a fixed cavity and a time-dependent external bath. In this situation we show that by chirping the reservoir modes sufficiently fast it is possible to inhibit, or dramatically enhance the decay of the atomic system, even though the gross reservoir structure is fixed. Thus it is possible to extract energy from a cavity-atom system faster than the empty cavity rate. Similar, but less dramatic effects are possible for moderate chirps where partial trapping of atomic population is also possible.

description: Deep reinforcement learning is an emerging machine learning approach which can teach a computer to learn from their actions and rewards similar to the way humans learn from experience. It offers many advantages in automating decision processes to navigate large parameter spaces. This paper proposes a novel approach to the efficient measurement of quantum devices based on deep reinforcement learning. We focus on double quantum dot devices, demonstrating the fully automatic identification of specific transport features called bias triangles. Measurements targeting these features are difficult to automate, since bias triangles are found in otherwise featureless regions of the parameter space. Our algorithm identifies bias triangles in a mean time of less than 30 minutes, and sometimes as little as 1 minute. This approach, based on dueling deep Q-networks, can be adapted to a broad range of devices and target transport features. This is a crucial demonstration of the utility of deep reinforcement learning for decision making in the measurement and operation of quantum devices.
Roughing it in Phuket, but the Jones’ haven’t been there (yet) : reconceptualizing tourism and community development in southern Thailand
Creators: name: Kontogeorgopoulos, Nick
Publisher: name: University of British Columbia
Year: 2009

description: This thesis examines the contribution made by "alternative" tourism towards community development in the provinces of Phuket, Phangnga, and Krabi in southern Thailand. Aside from providing novel, adventurous, and presumably authentic travel experiences, "alternative" tourism promotes forms of community development characterized by equitable distribution of resources, quality of life, and environmental sustainability. Alongside conventional, mass tourism development in southern Thailand, nature-based "alternative" travel activities such as sea kayaking and jungle trekking have grown increasingly popular among foreign tourists and have emerged as measures of diversification within a slowly stagnating regional tourist trade. This study assesses "alternative" tourism along the lines of the tourism industry, tourist, and host perspectives, and addresses three key issues, or themes: "alternative" tourism as a theoretical and practical "alternative" to conventional, mass tourism; the role played by authenticity and ethical concern in distinguishing "alternative travellers" from mass tourists; and "alternative" tourism's contribution to community-based economic, social, and environmental development in southern Thailand. The results of this study are based upon several types of data, including selfadministered surveys, analysis of statistical and other documentary sources, field observations, and interviews with tourists, government officials, company owners, and Thais working in the tourism industry. Three central findings emerge from this research. First, "alternative" tourism in southern Thailand shares many structural and conceptual links with the existing mass tourism industry. Rather than signalling a true departure from conventional, packaged tourism, "alternative" tourism constitutes a regenerative niche in Phuket's mass tourism industry. Second, discrepant expectations of, and levels of desire for, authenticity serve to differentiate categories of "alternative" tourists, many of whom display insensitive behaviour and place inappropriate demands on their Thai hosts. Third, certain forms of "alternative" tourism, such as "mass ecotourism," foster equitable community development, while others, such as backpacking and adventure travel, remain limited as engines of economic development. In addition to discussing theoretical and policy implications, the thesis concludes with a localized model of "alternative" tourism in southern Thailand.

description: Diffractometric biosensing is a promising technology to overcome critical limitations of refractometric biosensors, the dominant class of label-free optical transducers. These limitations manifest themselves by higher noise and drifts due to insufficient rejection of refractive index fluctuations caused by variation in temperature, solvent concentration, and most prominently, non-specific binding. Diffractometric biosensors overcome these limitations with inherent self-referencing on the submicron scale with no compromise on resolution. Despite this highly promising attribute, the field of diffractometric biosensors has only received limited recognition. A major reason is the lack of a general quantitative analysis. This hinders comparison to other techniques and amongst different diffractometric biosensors. For refractometric biosensors, on the other hand, such a comparison is possible by means of the refractive index unit (RIU). In this publication, we suggest the coherent surface mass density, $Γ_{\rm{coh}}$, as a quantity for label-free diffractometric biosensors with the same purpose as RIU in refractometric sensors. It is easy to translate $Γ_{\rm{coh}}$ to the total surface mass density $Γ_{\rm{tot}}$, which is an important parameter for many assays. We provide a generalized framework to determine $Γ_{\rm{coh}}$ for various diffractometric biosensing arrangements which enables quantitative comparison. Additionally, the formalism can be used to estimate background scattering in order to further optimize sensor configurations. Finally, a practical guide with important experimental considerations is given to enable readers of any background to apply the theory. Therefore, this paper provides a powerful tool for the development of diffractometric biosensors and will help the field to mature and unveil its full potential.

description: The inelastic dark matter model is one kind of popular models for the light dark matter (DM) below $O(1)$ GeV. If the mass splitting between DM excited and ground states is small enough, the co-annihilation becomes the dominant channel for thermal relic density and the DM excited state can be long-lived at the collider scale. We study scalar and fermion inelastic dark matter models for $ {\cal O}(1) $ GeV DM at Belle II with $ U(1)_D $ dark gauge symmetry broken into its $Z_2$ subgroup. We focus on dilepton displaced vertex signatures from decays of the DM excited state. With the help of precise displaced vertex detection ability at Belle II, we can explore the DM spin, mass and mass splitting between DM excited and ground states. Especially, we show scalar and fermion DM candidates can be discriminated and the mass and mass splitting of DM sector can be determined within the percentage of deviation for some benchmark points. Furthermore, the allowed parameter space to explain the excess of muon $(g-2)_μ$ is also studied and it can be covered in our displaced vertex analysis during the early stage of Belle II experiment.

description: We present a simple method to derive the semiclassical equations of motion for a spinning particle in a gravitational field. We investigate the cases of classical, rotating particles (pole-dipole particles), as well as particles with intrinsic spin. We show that, starting with a simple Lagrangian, one can derive equations for the spin evolution and momentum propagation in the framework of metric theories of gravity and in theories based on a Riemann-Cartan geometry (Poincare gauge theory), without explicitly referring to matter current densities (spin and energy-momentum). Our results agree with those derived from the multipole expansion of the current densities by the conventional Papapetrou method and from the WKB analysis for elementary particles.

description: The work is a continuation of a paper by Iskhakov A.S. and Dinh N.T. "Physics-integrated machine learning: embedding a neural network in the Navier-Stokes equations". Part I // arXiv:2008.10509 (2020) [1]. The proposed in [1] physics-integrated (or PDE-integrated (partial differential equation)) machine learning (ML) framework is furtherly investigated. The Navier-Stokes equations are solved using the Tensorflow ML library for Python programming language via the Chorin's projection method. The Tensorflow solution is integrated with a deep feedforward neural network (DFNN). Such integration allows one to train a DFNN embedded in the Navier-Stokes equations without having the target (labeled training) data for the direct outputs from the DFNN; instead, the DFNN is trained on the field variables (quantities of interest), which are solutions for the Navier-Stokes equations (velocity and pressure fields). To demonstrate performance of the framework, two additional case studies are formulated: 2D turbulent lid-driven cavities with predicted by a DFNN (a) turbulent viscosity and (b) derivatives of the Reynolds stresses. Despite its complexity and computational cost, the proposed physics-integrated ML shows a potential to develop a "PDE-integrated" closure relations for turbulent models and offers principal advantages, namely: (i) the target outputs (labeled training data) for a DFNN might be unknown and can be recovered using the knowledge base (PDEs); (ii) it is not necessary to extract and preprocess information (training targets) from big data, instead it can be extracted by PDEs; (iii) there is no need to employ a physics- or scale-separation assumptions to build a closure model for PDEs. The advantage (i) is demonstrated in the Part I paper [1], while the advantage (ii) is the subject of the current paper.

description: We present an investigation of the metal enrichment of the intra-cluster medium (ICM) by galactic winds and merger-driven starbursts. We use combined N-body/hydrodynamic simulations with a semi-numerical galaxy formation model. The mass loss by galactic winds is obtained by calculating transonic solutions of steady state outflows, driven by thermal, cosmic ray and MHD wave pressure. The inhomogeneities in the metal distribution caused by these processes are an ideal tool to reveal the dynamical state of a galaxy cluster. We present surface brightness, X-ray emission weighted temperature and metal maps of our model clusters as they would be observed by X-ray telescopes like XMM-Newton. We show that X-ray weighted metal maps distinguish between pre- or post-merger galaxy clusters by comparing the metallicity distribution with the galaxy-density distribution: pre-mergers have a metallicity gap between the subclusters, post-mergers a high metallicity between subclusters. We apply our approach to two observed galaxy clusters, Abell 3528 and Abell 3921, to show whether they are pre- or post-merging systems. The survival time of the inhomogeneities in the metallicity distribution found in our simulations is up to several Gyr. We show that galactic winds and merger-driven starbursts enrich the ICM very efficiently after z=1 in the central (~ 3 Mpc radius) region of a galaxy cluster.

description: The realisation of precision cardiology requires novel techniques for the non-invasive characterisation of individual patients' cardiac function to inform therapeutic and diagnostic decision-making. The electrocardiogram (ECG) is the most widely used clinical tool for cardiac diagnosis. Its interpretation is, however, confounded by functional and anatomical variability in heart and torso. In this study, we develop new computational techniques to estimate key ventricular activation properties for individual subjects by exploiting the synergy between non-invasive electrocardiography and image-based torso-biventricular modelling and simulation. More precisely, we present an efficient sequential Monte Carlo approximate Bayesian computation-based inference method, integrated with Eikonal simulations and torso-biventricular models constructed based on clinical cardiac magnetic resonance (CMR) imaging. The method also includes a novel strategy to treat combined continuous (conduction speeds) and discrete (earliest activation sites) parameter spaces, and an efficient dynamic time warping-based ECG comparison algorithm. We demonstrate results from our inference method on a cohort of twenty virtual subjects with cardiac volumes ranging from 74 cm3 to 171 cm3 and considering low versus high resolution for the endocardial discretisation (which determines possible locations of the earliest activation sites). Results show that our method can successfully infer the ventricular activation properties from non-invasive data, with higher accuracy for earliest activation sites, endocardial speed, and sheet (transmural) speed in sinus rhythm, rather than the fibre or sheet-normal speeds.

description: The NSF funded EarthCube initiative began in 2011 with the vision to transform geoscience research by developing cyberinfrastructure to improve access, sharing, visualization, and analysis of all forms of geosciences data and related resources. As a community-governed effort, EarthCube's overarching scientific goal is to enable geoscientists to tackle the challenges of understanding and predicting complex and evolving solid Earth, hydrosphere, atmosphere, and space environment systems. In order to assist in the planning, the EarthCube Science Committee has developed a selection of resources for the NSF-GEO domain data workshops. The resources are intended: 1) to share some lessons learned from prior EarthCube NSF-sponsored domain workshops so that new ground can be covered, and 2) to offer both technology and community resources in data management for the Geosciences.

description: Confining sound is of significant importance for the manipulation and routing acoustic waves. We propose a Helmholtz resonator (HR) based subwavelength sound channel formed at the interface of two metamaterials, for this purpose. The confinement is quantified through (i) a substantial reduction of the pressure, and (ii) an increase in a specific acoustic impedance (defined by the ratio of the local pressure to the sound velocity) - to a very large value outside the channel. The sound confinement is robust to frequency as well as spatial disorder at the interface, as long as the interface related edge mode is situated within the band gap. A closed acoustic circuit was formed by introducing controlled disorder in the HR units at the corners, indicating the possibility of confining sound to a point.
