description: This study aims to analyze the dependence of reservoirs (locally called tanks or wewas) in the headwaters of the Aruvi Aru catchment on precipitation and thus to evaluate their efficiency. The Aruvi Aru is located in the Dry Zone of Sri Lanka, and numerous human made reservoirs characterize the study area. The methodology is based on the application and correlation of climatic and hydrological drought indices. The Standardized Precipitation Index (SPI) is applied to precipitation data at different time scales and the Standardized Water-Level Index (SWLI) is applied to water-level data of five major tanks in the catchment. The results show that near normal present-day average precipitation is appropriate to fill the investigated tanks. The precipitation of the previous 6–12 months has the highest impact on water-level changes. A moderate to strong positive correlation between SWLI and SPI point to other factors besides precipitation affecting the water level of the tanks. These are: (i) catchment size together with the buffering capacity of the upstream catchment and (ii) management practices. As the overall conclusion of our study shows, the tanks functioned efficiently within their system boundaries.

description: Urban development without adequate soil erosion control measures is becoming a major environmental concern in developing urban areas across Africa. These environmental disturbances encompass rampart Land Use and Land Cover changes (LULC) due to a high population growth rate and increased economic activities. To understand the influence of accelerated LULC changes and urban expansion as major drivers in landscape degradation in the Epworth district of the Harare Metropolitan Province, the RUSLE model was employed. This considers land use, soil, climate and topography as input parameters in the assessment of the extent and impact of these drivers on soil erosion. The Revised Universal Soil Loss Equation (RUSLE) was used to predict the potential erosion between 1984 and 2018 and soil erosion risk for the years 2000 and 2018. The mean rate of the predicted potential soil erosion was 13.2 t ha−1 yr−1 (1984–2018); areas especially vulnerable to erosion were predicted for foot slope areas with direct tributaries to the major streams and steep sloping zones. The average soil erosion risk was estimated at 1.31 t ha−1 yr−1 for the year 2000 and 1.12 t ha−1 yr−1 for 2018. While the overall potential soil loss decreased between 2000 and 2018, the potential soil loss was observed to increase tremendously in residential areas, which doubled in extent between 2000 and 2018. The findings reveal that about 40% of the Epworth district was threatened by unsustainable soil loss resulting from increased soil erosion risk within the built-up areas.
title: Reclaiming Pusey for theology: allegory, communion, and sacrifice
Creators: name: Karlowicz, Tobias Amadeus
Publisher: name: University of St Andrews
Year: 2013

description: Edward Bouverie Pusey once towered over nineteenth-century British theology, but he has now fallen into almost entire insignificance. However, analysis of this decline (Chapter 1) leads to a reassessment. His development—especially his complicated relationship with pre-Tractarian High Church Anglicanism—shows a deep criticism of post-Enlightenment intellectual trends, from his early years through his association with the Oxford Movement and the Tracts for the Times, to the end of his life (Chapter 2). This criticism led him to the patristic use of allegory, both as a biblical hermeneutic and as a creative, complex, image-based approach to theology (Chapter 3). His development of High Church theology (seen especially through comparison with Waterland) and his use of allegory can be traced throughout his theology. His understanding of union with Christ and theosis reveals both: the sacraments have a strong symbolic dimension, while his positions on baptismal regeneration and the real presence of Christ in the Eucharist show a development rather than a rejection of earlier High Church theology (Chapters 4 and 5). His understanding of the atonement blends High Church reliance on sacrificial types with his unitive theology to reconfigure traditional satisfaction theory as restoration of love for God, rather than redemption from punishment—a position which marks Pusey as an important transitional figure in 19th c. theology (Chapter 6). The flexibility of Pusey’s allegorical approach also allows him to blend a High Church tradition of spiritual sacrifice with sacramental participation in Christ’s self-offering, so that sacrifice becomes an aspect of union with Christ (Chapter 7). Pusey’s use of allegory shows similarities to postmodern theology, while his development of High Church theology shows his originality (Chapter 8).
Stress and sleep : predictors of failure to recover
Creators: name: Ellis, Alena Talbot
Publisher: name: University of British Columbia
Year: 2010

description: Delayed recovery after cardiovascular response to a stressor is currently being recognized as a marker and likely contributing factor in the development of cardiovascular disease. Interestingly, the psychological variables that predict delayed recovery appear similar to those associated with poor sleep quality. As such, poor sleep may be another index of delayed recovery. This study attempted to expound the relationship between psychological predictors of recovery and sleep and determine whether these outcomes do indeed share common predictors. Sleep quality is defined as total sleep time determined by actigraph measurements. One hundred and thirty six participants were subjected to a mental stress task coupled with harassment after which speed of recovery was assessed. In these same individuals, sleep quality data for the night following the lab stress procedure were collected. Results were not in support of our overall hypothesis. Slower rates of recovery were associated with caffeine consumption prior to experiment time, as well as anger rumination, however, with identifiable gender effects, while total sleep time was predicted by hostility in the overall sample and by higher rates of worry in male participants.
Direct measurement of the interactions between cationic surfactant bilayers
Creators: name: Leivers, Matthew
Publisher: name: Imperial College London
Year: 2019

description: Understanding the interactions between vesicles within a vesicle dispersion is key to understanding the stability of the dispersion. If the interactions between the vesicles are sufficiently repulsive the system will be stable. Whilst this behaviour is relatively easy to predict for simple colloid and vesicle dispersions. In complex systems, containing various additives such as salts, polymers, and polyelectrolytes, the interactions effecting the stability of the dispersion are more complex. In this study methodologies for directly measuring the interactions between two supported cationic surfactant bilayers using the colloidal probe atomic force microscopy technique were successfully developed. The surfactant vesicle system of interest in this work was the double tailed, cationic surfactant DIPEDMAMS, often used in commercial fabric softeners. The system was observed to form two co-existing lamellar phases which melt to forma a single fluid lamellar phase at around $~$\SI{40}{\degreeCelsius}. The addition of different alkyl alcohols was used to modify the transition temperature to create supported bilayers for the colloidal probe technique. Electrolytes were observed to decrease the repulsive interactions between the bilayers with the identity of the salt determining the strength of the effect. Polyelectrolytes whilst having a similar impact as to the salts the depletion attraction was also observed and shown to be dependent on the molecular weight of the polymer. The interactions with uncharged polymers were complex due to the absorption of the polymer to the bilayers as observed by AFM imaging. The addition of fatty acids to simulate the breakdown of the surfactant molecules within the bilayers exhibited complex behaviour dependent on the nature of the fatty acid in question. All these measurements were supported by AFM imaging and x-ray scattering to decouple changes to the supported bilayers and the interactions between them. Finally, direct force measurements were compared to the behaviour of the bulk vesicle dispersions.

description: We investigate both from a qualitative as well as quantitative perspective the emergence of chaos in the QCD confining string in a magnetic field from a holographic viewpoint. We use an earlier developed bottom-up solution of the Einstein-Maxwell-Dilaton action that mimics QCD and its thermodynamics quite well. Surprisingly, our predictions depend on the used frame: the magnetic field tends to suppress the chaos in both perpendicular and parallel directions relative to the magnetic field in the string frame whilst in the Einstein frame, the chaos suppression only happens in the perpendicular direction, with an enhanced chaos along the magnetic field. The amount of suppression/enhancement in both frames does depend on the relative orientation of the string and magnetic field.

The warrior maiden and the divorcée : the universal past tense of the traditional chinese theatre
Creators: name: Stenberg, Joshua Sidney
Publisher: name: University of British Columbia
Year: 2010

description: in this essay, I examine two rather different “historical” narratives of the traditional stage in order to identify the specific temporal relationship between the historical record and the Chinese stage. The first example, the story of Zhu Maichen and his wife, traces the narrative of a female-initiated divorce from its initial appearance in canonical history, through fiction and poetry, and into late Imperial and ultimately modem and contemporary Kunju theatre, with reference to related theatre traditions. As social mores shifted, the narrative was alteredto fit with meanings appropriate to the times. The second example, “Slaying the Tiger,” (Ci hu) examines the story of a female assassin as it appears in unofficial and standard histories, and in the Kunju tradition. The narrative plays fast and loose with historical “fact” in order to enhance its theatrical effect. The character of the main character is formed not by historical record, but by xiqu convention. Costume and props do not indicate era. Representations of history in traditional Chinese theatre take place in a single, unspecific past tense; history is mined as a repository of “stories” (the vocabulary of the theatre) but does not bear on the manner of the telling.

description: In this paper we present new structural information about the multiplier algebra Mult (A) of a sigma-unital purely infinite simple C*-algebra A, by characterizing the positive elements a in Mult(A) that are strict sums of projections belonging to A. If a is not in A and is not a projection, then the necessary and sufficient condition for a to be a strict sum of projections belonging to A is that the norm ||a||>1 and that the essential norm ||a||_ess >=1. Based on a generalization of the Perera-Rordam weak divisibility of separable simple C*-algebras of real rank zero to all sigma-unital simple C*-algebras of real rank zero, we show that every positive element of A with norm greater than 1 can be approximated by finite sums of projections. Based on block tri-diagonal approximations, we decompose any positive element a in Mult(A) with ||a||>1 and ||a||_ess >=1 into a strictly converging sum of positive elements in A with norm greater than 1.

Interprofessional Collaboration: the attitudes of newly graduated physicians in Oman
Creators: name: Awadh, Heba
Publisher: name: Imperial College London
Year: 2019

description: Interprofessional collaboration (IPC) has gained acceptance among healthcare professionals as a means to improve communication and, therefore, the quality of services provided to patients. There is limited published evidence on IPC among newly graduated physicians (NGPs), who are often confronted with academic pressure, job demands and patient safety concerns. The study sought to assess the attitudes of NGPs to IPC and examine the perceptions of healthcare professionals in Oman of the enablers of and barriers to IPC. A mixed method design was adopted to comprehensively address the exploratory and explanatory research questions. The first phase of the study consisted of an online self-administered survey of NGPs using the Jefferson School of Attitudes Toward Physician-Nurse Collaboration (JSAPNC). The survey data were analysed using SPSS software version 24. The second phase consisted of focus group discussions, with each group comprising four to eight healthcare professionals. The focus group data were analysed using the interpretive phenomenological approach with N-Vivo software version 12. The findings indicated that a general ‗collaborative spirit‘ is prevalent among NGPs in Oman, with an overall JSAPNC score of 48. Male physicians expressed more favourable attitudes towards IPC and endorsed a more positive view of nurses‘ contribution to the psychological and educational aspects of patient care than did their female counterparts. Male physicians also demonstrated greater agreement with nurse involvement in decisions regarding patient care and policies. The study also showed that prior knowledge of IPC impacted positively on collaboration among professionals, which in turn is likely to impact on the healthcare delivery. It is therefore necessary to implement robust strategies, such as interprofessional education (IPE) and training, to promote IPC among healthcare professionals.

description: We develop structure preserving schemes for a class of nonlinear mobility continuity equation. When the mobility is a concave function, this equation admits a form of gradient flow with respect to a Wasserstein-like transport metric. Our numerical schemes build upon such formulation and utilize modern large scale optimization algorithms. There are two distinctive features of our approach compared to previous ones. On one hand, the essential properties of the solution, including positivity, global bounds, mass conservation and energy dissipation are all guaranteed by construction. On the other hand, it enjoys sufficient flexibility when applies to a large variety of problems including different free energy functionals, general wetting boundary conditions and degenerate mobilities. The performance of our methods are demonstrated through a suite of examples.

description: Unsharp POVM measurements allow the estimation and tracking of quantum wavefunctions in real-time with minimal disruption of the dynamics. Here we demonstrate that high fidelity state monitoring, and hence quantum control, is possible even in the presence of classical dephasing and amplitude noise, by simulating such measurements on a two-level system undergoing Rabi oscillations. Finite estimation fidelity is found to persist indefinitely long after the decoherence times set by the noise fields in the absence of measurement.

description: Competing short- and long-range interactions represent distinguished ingredients for the formation of complex quantum many-body phases. Their study is hard to realize with conventional quantum simulators. In this regard, Rydberg atoms provide an exception as their excited manifold of states have both density-density and exchange interactions whose strength and range can vary considerably. Focusing on one-dimensional systems, we leverage the van der Waals and dipole-dipole interactions of the Rydberg atoms to obtain the zero-temperature phase diagram for a uniform chain and a dimer model. For the uniform chain, we can influence the boundaries between ordered phases and a Luttinger liquid phase. For the dimerized case, a new type of bond-order-density-wave phase is identified. This demonstrates the versatility of the Rydberg platform in studying physics involving short- and long-ranged interactions simultaneously.

description: African American (AA) women have an excessive risk of developing triple-negative breast cancer (TNBC). We employed Assay for Transposase-Accessible Chromatin using sequencing to characterize differences in chromatin accessibility between nine commonly used TNBC cell lines de?rived from patients of European and African ancestry. Principal component and chromosome mapping analyses of accessibility peaks with the most variance revealed separation of chromatin profiles by patient group. Motif enrichment and footprinting analyses of disparate open chromatin regions revealed differences in transcription factor activity, identifying 79 with ancestry-associated binding patterns (FDR < 0.01). AA TNBC cell lines ex?hibited increased accessibility for 62 transcription factors associated with epithelial-to-mesenchymal transition, cancer stemness/chemotherapeutic resistance, proliferation, and aberrant p53 regulation, as well as KAISO, which has been previously linked to aggressive tumor characteristics in AA patients with cancer. Differential Assay for Transposase-Accessible Chromatin signal analysis identified 1,596 genes located within promoters of differentially open chromatin regions in AA-derived TNBC, identifying DNA methyltransferase 1 as the top upregulated gene associated with African ancestry. Pathway analyses with these genes revealed enrichment in several pathways, including hypoxia. Culturing cells under hypoxia showed ancestry-specific stress responses that led to the identification of a core set of AA-associated transcription factors, which included members of the Kruppel-like factor and Sp subfamilies, as well as KAISO, and identified ZDHHCI, a gene previously implicated in immunity and STING activation, as the top upregulated AA-specific gene under hypoxia. Together, these data reveal a differential chromatin landscape in TNBC associated with donor ancestry. The open chromatin structure of AA TNBC may contribute to a more lethal disease.

description: Preserving the quality of positron beams in plasma-based accelerators, where wakefields are generated in electron filaments, is challenging. These wakefields are characterized by transversely non-linear focusing fields and non-uniform accelerating fields. However, a nonzero plasma temperature linearizes the transverse wakefield within the central region of the electron filament. In this study, we employ 3D particle-in-cell simulations with mesh refinement to demonstrate that beams with emittances on the order of tens of nanometers are contained within the linearized region of the transverse wakefield. This enables emittance preservation to one percent, while positron beams with the same charge and micrometer emittances, which sample the non-linear part of the transverse wakefield, experience a relative emittance growth of ten percent. Additionally, we observe a significant reduction in the growth rate of the slice energy spread for the tens of nanometers emittance beams in comparison to the micrometer emittance beams. The utilization of warm plasmas in conjunction with low-emittance beams opens up new avenues for enhancing the beam quality across various plasma-based positron acceleration approaches.
Protecting applications using trusted execution environments
Creators: name: Priebe, Christian
Publisher: name: Imperial College London
Year: 2020

description: While cloud computing has been broadly adopted, companies that deal with sensitive data are still reluctant to do so due to privacy concerns or legal restrictions. Vulnerabilities in complex cloud infrastructures, resource sharing among tenants, and malicious insiders pose a real threat to the confidentiality and integrity of sensitive customer data. In recent years trusted execution environments (TEEs), hardware-enforced isolated regions that can protect code and data from the rest of the system, have become available as part of commodity CPUs. However, designing applications for the execution within TEEs requires careful consideration of the elevated threats that come with running in a fully untrusted environment. Interaction with the environment should be minimised, but some cooperation with the untrusted host is required, e.g. for disk and network I/O, via a host interface. Implementing this interface while maintaining the security of sensitive application code and data is a fundamental challenge. This thesis addresses this challenge and discusses how TEEs can be leveraged to secure existing applications efficiently and effectively in untrusted environments. We explore this in the context of three systems that deal with the protection of TEE applications and their host interfaces: SGX-LKL is a library operating system that can run full unmodified applications within TEEs with a minimal general-purpose host interface. By providing broad system support inside the TEE, the reliance on the untrusted host can be reduced to a minimal set of low-level operations that cannot be performed inside the enclave. SGX-LKL provides transparent protection of the host interface and for both disk and network I/O. Glamdring is a framework for the semi-automated partitioning of TEE applications into an untrusted and a trusted compartment. Based on source-level annotations, it uses either dynamic or static code analysis to identify sensitive parts of an application. Taking into account the objectives of a small TCB size and low host interface complexity, it defines an application-specific host interface and generates partitioned application code. EnclaveDB is a secure database using Intel SGX based on a partitioned in-memory database engine. The core of EnclaveDB is its logging and recovery protocol for transaction durability. For this, it relies on the database log managed and persisted by the untrusted database server. EnclaveDB protects against advanced host interface attacks and ensures the confidentiality, integrity, and freshness of sensitive data.

description: We study the turbulence induced in the dust layer of a protoplanetary disk based on the energetics of dust accretion due to gas drag. We estimate turbulence strength from the energy supplied by dust accretion, using the radial drift velocity of the dust particles in a laminar disk. Our estimate of the turbulence strength agrees with previous analytical and numerical research on the turbulence induced by Kelvin-Helmholtz and/or streaming instabilities for particles whose stopping time is less than the Keplerian time. For such small particles, the strongest turbulence is expected to occur when the dust-to-gas ratio of the disk is ~C_eff^(1/2) (h_g / r) ~ 10^(-2), where C_eff ~ 0.2 represents the energy supply efficiency to turbulence and h_g / r ~ 5 x 10^(-2) is the aspect ratio of the gas disk. The maximum viscosity parameter is alpha_max ~ C_eff T_s (h_g / r)^2 ~ 10^(-4) T_s, where T_s (<1) is the non-dimensional stopping time of the dust particles. Modification in the dust-to-gas ratio from the standard value, 10^(-2), by any process, results in weaker turbulence and a thinner dust layer, and consequently may accelerate the growth process of the dust particles.

Immersive social visual analytics

Publisher: name: Imperial College London
Year: 2019

description: Increase in data availability in the last decades started a new multi-disciplinary and data-driven approach to be taken in research projects. This new approach requires a matching set of data analytics methods that can target the broadness of data and mixture of expertise in those research projects. We believe that Large High Resolution Display (LHRD) based Immersive and Social Visual Data Analytics system is the solution. LHRDs are large scale display walls that are built for research purposes, which are ideal for conducting the visual data analytics these multi-disciplinary data-driven research approach requires, by providing unique properties in terms of immersion, collaboration, visualisation and interactivity. This thesis surveyed existing software in the literature for LHRDs and identified many challenges that needed to be solved, in order to conduct visual data analytics for this objective. Hence, this thesis introduces and demonstrates its novel Clustered Visualisation Services Paradigm (CVSP) in its Data Observatory Software Framework (GDO) for conducting Immersive and Social Visual Data Analytics on LHRDs. This paradigm enables system and visualisation app logics to have components on distributed locations of LHRD, where these components communicate, coordinate and form functionality through structured communication using APIs. Through this paradigm, we enable implementation of immersive and scalable display of versatile, modular, general, interactive, data-driven data visualisation applications and we also enable management of them through our underlying operating system. Furthermore, this paradigm enables collaging and syncing of applications for creating coordinated data visualisation scenes composed of multi-view visualisations that can implement complex interaction scenarios on LHRDs. In summary, this thesis presents architecture and implementation of Data Observatory Software Framework (GDO), which is used at KPMG Data Observatory, Data Science Institute, Imperial College London; its novel software paradigm: Clustered Visualisation Services Paradigm (CVSP) and many novel or critical functionality provided by this paradigm that overcomes challenges for conducting Immersive and Social Visual Data Analytics for multi-disciplinary data-driven research projects.

description: In materials science the phase field crystal approach has become popular to model crystallization processes. Phase field crystal models are in essence Landau-Ginzburg-type models, which should be derivable from the underlying microscopic description of the system in question. We present a study on classical density functional theory in three stages of approximation leading to a specific phase field crystal model, and we discuss the limits of applicability of the models that result from these approximations. As a test system we have chosen the three--dimensional suspension of monodisperse hard spheres. The levels of density functional theory that we discuss are fundamental measure theory, a second-order Taylor expansion thereof, and a minimal phase-field crystal model. We have computed coexistence densities, vacancy concentrations in the crystalline phase, interfacial tensions and interfacial order parameter profiles, and we compare these quantities to simulation results. We also suggest a procedure to fit the free parameters of the phase field crystal model.

The p-process nucleosynthesis in core-collapse supernovae
Creators: name: Roberti, Lorenzo
Publisher: name: Zenodo
Year: 2023

description: Neutron-capture processes made most of the abundances of heavy elements in the Solar System, however they cannot produce a number of rare proton-rich stable isotopes lying on the left side of the valley of stability. The p-process, or γ-process, is recognised and generally accepted as a feasible process for the synthesis of proton-rich nuclei in core collapse supernovae. However this scenario still leaves some puzzling discrepancies between theory and observations. My aim is to explore in more detail the p-process production from massive stars in different sets of models and using the latest nuclear reaction rates. Here I will show some of the result of my analysis, by identifying the p-process sites and focusing on supernova progenitors that experience a C-O shell merger just before the collapse of the Fe core. Finally, I will also discuss how the p-process depends on the different core-collapse supernova prescription.

description: Effective instructional design decisions can be made when they are founded on evidence-based research into the science of learning and the science of instruction. Together these disciplines form the foundation and provide the framework to guide the instructional design process to ensure successful student learning. This Project addresses the Critical Challenge Question (CCQ): How can an understanding of the science of learning and the science of instruction support effective instructional design practices for online learning? Through the process of conducting a literature review on this topic, many overlapping concepts and connections were found among the constructs, theories, principles, and models. This research was the basis for my MEdL Project Build, a website resource for myself and other educators who seek to design instruction that results in effective and successful learning for all students.

description: The overuse of antibiotics in treating urinary tract infections (UTIs) has led to increased bacterial resistance, complicating UTI management. Actinomycetota (previously known as Actinobacteria), are a prolific source of bioactive compounds with therapeutic potential. Saccharothrix algeriensis DSM 44581, a bacterium isolated from Algerian Saharan soil, produces various dithiolopyrrolone antibiotics depending on the composition of its culture medium. This study aimed to evaluate its antibacterial activity against multidrug−resistant uropathogenic bacteria. The antibacterial activity of S. algeriensis was assessed in a semi-synthetic fermentation broth under three conditions: semi-synthetic medium (SSM) without adding precursors, SSM supplemented with sorbic acid, and SSM added with cystine. Fifty uropathogenic strains were used as target bacteria, including forty strains from the family Enterobacteriaceae and ten strains of Staphylococcus saprophyticus, all with diverse antibiotic resistance profiles. Inhibition diameters varied with culture conditions: 0-40.33 mm in SSM without precursors, 0-39 mm in SSM with sorbic acid, and 0-35 mm in SSM with cystine. Furthermore, two specific antibiotics produced by S. algeriensis, thiolutin and 2-hexonyl-pyrrothine, were purified using high-performance liquid chromatography (HPLC), and their Minimum Inhibitory Concentrations (MICs) were determined against the uropathogenic strains. These antibiotics exhibited moderate to high activity against Staphylococcus saprophyticus, with MICs ≤75 μg/mL. In contrast, they showed low to no activity against Enterobacteriaceae, with MICs exceeding 150 μg/ mL. These findings suggest that S. algeriensis could be a promising source of antibiotics efficient against Staphylococcus saprophyticus.
2D-1D Wavelet Reconstruction As A Tool For Source Finding In Spectroscopic Imaging Surveys

description: Today, image denoising by thresholding of wavelet coefficients is a commonly used tool for 2D image enhancement. Since the data product of spectroscopic imaging surveys has two spatial and one spectral dimension, the techniques for denoising have to be adapted to this change in dimensionality. In this paper we will review the basic method of denoising data by thresholding wavelet coefficients and implement a 2D-1D wavelet decomposition to obtain an efficient way of denoising spectroscopic data cubes. We conduct different simulations to evaluate the usefulness of the algorithm as part of a source finding pipeline.

Globalization and the challenge of urban development in Uganda : implication on land use planning in Kampala
Creators: name: Hirabe, Nur Osman
Publisher: name: University of British Columbia

description: This study is concerned with the challenges of urban planning in Kampala, the capital city of Uganda, in the era of economic globalization. The emergence of the global economy, an important facet of globalization, has radically transformed urban landscapes around the world. It has increased urban populations (Zetter and Hamza, 2004), restructured the political economy of cities through decentralization (Frobel, et. al., 1980), created economic opportunities for some while impoverishing others, and changed the nature of urban development policies around the world. These transformations are exerting new forms of economic, political, and environmental pressures on Kampala's city authority. The study finds that while globalization has brought noticeable economic gains in Uganda, it has also created an ineffective decentralized system that compromised the effectiveness of the urban planning system of Kampala, which led to conflict and confusion over decision making responsibilities throughout all levels of governments including ministries and departments. Consequently, Kampala is growing without planning guidance. How has this come about?
Spin-orbital physics for p orbitals in alkali RO_2 hyperoxides --- generalization of the Goodenough-Kanamori rules

description: We derive a realistic spin-orbital model at finite Hund's exchange for alkali hyperoxides. We find that, due to the geometric frustration of the oxygen lattice, spin and orbital waves destabilize both spin and p-orbital order in almost all potential ground states. We show that the orbital order induced by the lattice overrules the one favoured by superexchange and that this, together with the large interorbital hopping, leads to generalized Goodenough-Kanamori rules. They (i) lift the geometric frustration of the lattice, and (ii) explain the observed layered C-type antiferromagnetic order in alkali hyperoxides. This is confirmed by a spin-wave dispersion with no soft-mode behavior presented here as a prediction for future experiments.

description: This paper presents the findings of a research project that sought to interrogate the possibilities of digital storytelling as a pathway towards a more complete understanding of treaties and the treaty relationship in western Canada. This research is situated in the province of Saskatchewan, where treaty education (that is, education about the history of the numbered treaties signed between First Nations people and the British Crown, as well as the subsequent history of the treaty relationship) has been mandatory for almost a decade.

The paper details a two-year journey alongside elementary educators as they used digital storytelling to take up treaty education in their classrooms. We present an overview of the research project as well as the narratives of a teacher, a researcher, and a Cree knowledge keeper, all of whom were involved in and reflected on the research journey. We consider the research findings alongside these narratives in order to explore the possibilities that digital storytelling might offer as we, as a Canadian nation, move towards reconciliation with Aboriginal people within a Canadian context of ongoing colonialism.

Questo articolo presenta i risultati di un progetto di ricerca che ha cercato di indagare sulle possibilità della narrazione digitale di storie (storytelling) come percorso verso una comprensione più completa dei trattati e del rapporto fra i trattati nel Canada occidentale. Questa indagine è situata nella provincia di Saskatchewan, dove l'istruzione sui trattati (cioè, l'educazione sulla storia dei trattati numerati firmati tra la Prima Nazione e la Corona Britannica, così come la storia successiva del rapporto fra i trattati) è stato obbligatorio per quasi un decennio.
Il saggio riporta un percorso di due anni con insegnanti di scuola elementare che hanno usato lo storytelling digitale per fare l'educazione ai trattati nelle loro classi. Presentiamo una panoramica del progetto di ricerca ed i racconti di un insegnante, di un ricercatore, e un guardiano Cree della conoscenza, i quali sono stati coinvolti nella ricerca e riflettono sul percorso svolto. Consideriamo i risultati dell’indagine insieme a questi racconti, al fine di esplorare le possibilità che la narrazione digitale potrebbe offrire dato che noi, come nazione canadese, procediamo verso la riconciliazione con gli aborigeni in un contesto canadese di colonialismo in corso.

description: Code switching and code mixing commonly happen to a speaker who speaks two or more language. Mostly code switching and code mixing occurs in oral speech. This research aims to describe code switching and code mixing on “Breakout” special episode of Jessie J.’s oral speech of host and guest star are the objects of this research. They often do code switching and code mixing on their oral speech. This study uses descriptive method. Technique of analyzing data is focused on host (Boy William) and guest star’s (Jessie J.) speech so we could know code switching and code mixing that happen also the factors itself. The result shows that there are seventeen code switching and code mixing’s data. There are three intern code switchings, seven extern code switchings, two word code mixings, and five phrase code mixing. Some factors which cause code switching and code mixing from “Breakout” are speakers and topic.
