The meaning of violence : a journey of understanding through the Rift Valley of Kenya
Creators: name: Bicknell, Joshua
Publisher: name: University of British Columbia
Year: 2010

description: On the 30th December 2007, following the disputed presidential election fought between Raila Odinga of the ODM Party and Mwai Kibaki of the PNU Party, violence erupted in the Rift Valley of Kenya. Focusing on the Kalenjin and Kikuyu ethnicities this paper takes a hermeneutical approach and argues that explanations of violence will always be incomplete without a prior understanding of what violence means for the different communities involved. It argues that this understanding comes from the dominant traditions of violence that people grow up in, which are constructed and held in narrative form. From this theoretical approach and building on five weeks of fieldwork conducted in the Rift Valley of Kenya in the September and October of 2010, the argument proceeds that in both the Kikuyu and Kalenjin communities storylines were constructed by the elites and opinion makers, building on existing narratives and framing events and experiences. These storylines were then reproduced at a local level and constructed violence as legitimate, necessary and directly led to fighting. From this conclusion, the final part of this paper suggests that by comprehending the compelling narratives leading to violence, persuasive counter-narratives can be introduced and strengthened, which might deconstruct violence as legitimate and make communities want peace. Overall, it is suggested that a hermeneutical approach to violence is valuable and must be pursued where the overriding goal is peace and human dignity.

description: In the debate surrounding contemporary approaches to copyright law, the voice of songwriters has been significantly under-represented. This thesis presents the findings of seven interviews with practising Western Canadian singer-songwriters regarding the use of pre-existing intellectual property in their creative process, as well as their understanding of and attitudes towards copyright law. These findings are placed within the context of current theoretical approaches to creativity, and are compared to the beliefs about creativity inherent in current copyright law. While the laws are based on an individualistic view of creativity, the songwriters themselves show a tendency to draw heavily from songs, film and other media when creating their works, and tend to view copyright itself as largely irrelevant to their creative habits.

description: Background

Vitamin-D-binding protein (VDBP) is a low molecular weight protein that is filtered through the glomerulus as a 25-(OH) vitamin D 3/VDBP complex. In the normal kidney VDBP is reabsorbed and catabolized by proximal tubule epithelial cells reducing the urinary excretion to trace amounts. Acute tubular injury is expected to result in urinary VDBP loss. The purpose of our study was to explore the potential role of urinary VDBP as a biomarker of an acute renal damage.

Method

We included 314 patients with diabetes mellitus or mild renal impairment undergoing coronary angiography and collected blood and urine before and 24 hours after the CM application. Patients were followed for 90 days for the composite endpoint major adverse renal events (MARE: need for dialysis, doubling of serum creatinine after 90 days, unplanned emergency rehospitalization or death).

Results

Increased urine VDBP concentration 24 hours after contrast media exposure was predictive for dialysis need (no dialysis: 113.06 +/- 299.61ng/ml, n = 303; need for dialysis: 613.07 +/- 700.45 ng/ml, n = 11, Mean +/- SD, p < 0.001), death (no death during follow-up: 121.41 +/- 324.45 ng/ml, n = 306; death during follow-up: 522.01 +/- 521.86 ng/ml, n = 8; Mean +/- SD, p < 0.003) and MARE (no MARE: 112.08 +/- 302.00ng/ml, n = 298; MARE: 506.16 +/- 624.61 ng/ml, n = 16, Mean +/- SD, p < 0.001) during the follow-up of 90 days after contrast media exposure. Correction of urine VDBP concentrations for creatinine excretion confirmed its predictive value and was consistent with increased levels of urinary Kidney Injury Molecule1 (KIM-1) and baseline plasma creatinine in patients with above mentioned complications. The impact of urinary VDBP and KIM-1 on MARE was independent of known CIN risk factors such as anemia, preexisting renal failure, preexisting heart failure, and diabetes.

Conclusions

Urinary VDBP is a promising novel biomarker of major contrast induced nephropathy-associated events 90 days after contrast media exposure.

description: This report overviews studies accomplished in the U70 proton synchrotron of IHEP-Protvino during the recent two decades. Major attention is paid to a routine application of bent crystals for beam extraction from the machine. It has been confirmed experimentally that efficiency of beam extraction with a crystal deflector of around 85% is well feasible for a proton beam with intensity up to 1012 protons per cycle. Another trend is to use bent crystals for halo collimation in a high energy collider. New promising options emerge for, say, LHC and ILC based on the "volume reflection" effect, which has been discovered recently in machine study runs at U70 of IHEP (50 GeV) and SPS of CERN (400 GeV).

description: Linking together the processes of rapid physical erosion and the resultant chemical dissolution of rock is a crucial step in building an overall deterministic understanding of weathering in mountain belts. Landslides, which are the most volumetrically important geomorphic process at these high rates of erosion, can generate extremely high rates of very localised weathering. To elucidate how this process works we have taken advantage of uniquely intense landsliding, resulting from Typhoon Morakot, in the T'aimali River and surrounds in southern Taiwan. Combining detailed analysis of landslide seepage chemistry with estimates of catchment-by-catchment landslide volumes, we demonstrate that in this setting the primary role of landslides is to introduce fresh, highly labile mineral phases into the surface weathering environment. There, rapid weathering is driven by the oxidation of pyrite and the resultant sulfuric-acid-driven dissolution of primarily carbonate rock. The total dissolved load correlates well with dissolved sulfate - the chief product of this style of weathering - in both landslides and streams draining the area (R-2 = 0.841 and 0.929 respectively; p < 0.001 in both cases), with solute chemistry in seepage from landslides and catchments affected by significant landsliding governed by the same weathering reactions. The predominance of coupled carbonate-sulfuric-acid-driven weathering is the key difference between these sites and previously studied landslides in New Zealand (Emberson et al., 2016), but in both settings increasing volumes of landslides drive greater overall solute concentrations in streams.

Bedrock landslides, by excavating deep below saprolite-rock interfaces, create conditions for weathering in which all mineral phases in a lithology are initially unweathered within landslide deposits. As a result, the most labile phases dominate the weathering immediately after mobilisation and during a transient period of depletion. This mode of dissolution can strongly alter the overall output of solutes from catchments and their contribution to global chemical cycles if landslide-derived material is retained in catchments for extended periods after mass wasting.

description: In contrast to recent advances in projecting sea levels, estimations about the economic impact of sea level rise are vague. Nonetheless, they are of great importance for policy making with regard to adaptation and greenhouse-gas mitigation. Since the damage is mainly caused by extreme events, we propose a stochastic framework to estimate the monetary losses from coastal floods in a confined region. For this purpose, we follow a Peak-over-Threshold approach employing a Poisson point process and the Generalised Pareto Distribution. By considering the effect of sea level rise as well as potential adaptation scenarios on the involved parameters, we are able to study the development of the annual damage. An application to the city of Copenhagen shows that a doubling of losses can be expected from a mean sea level increase of only 11 cm. In general, we find that for varying parameters the expected losses can be well approximated by one of three analytical expressions depending on the extreme value parameters. These findings reveal the complex interplay of the involved parameters and allow conclusions of fundamental relevance. For instance, we show that the damage typically increases faster than the sea level rise itself. This in turn can be of great importance for the assessment of sea level rise impacts on the global scale. Our results are accompanied by an assessment of uncertainty, which reflects the stochastic nature of extreme events. While the absolute value of uncertainty about the flood damage increases with rising mean sea levels, we find that it decreases in relation to the expected damage.

description: The ionizing fluxes from quasars and other active galactic nuclei (AGN) are critical for interpreting the emission-line spectra of AGN and for photoionization and heating of the intergalactic medium. Using ultraviolet spectra from the Cosmic Origins Spectrograph (COS) on the Hubble Space Telescope (HST), we have directly measured the rest-frame ionizing continua and emission lines for 22 AGN. Over the redshift range 0.026 < z < 1.44, COS samples the Lyman continuum and many far-UV emission lines (Lya 1216, C IV 1549, Si IV/OIV] 1400, N V 1240, O VI 1035). Strong EUV emission lines with 14-22 eV excitation energies (Ne VIII 770,780, Ne V 569, O II 834, O III 833, 702, O IV 788,608,554, O V 630, N III 685) suggest the presence of hot gas in the broad emission-line region. The rest-frame continuum, F_nu ~ nu^{alpha_nu}, shows a break at wavelengths below 1000 A, with spectral index alpha_nu = -0.68 +/- 0.14 in the FUV (1200-2000 A) steepening to alpha_nu = -1.41 +/- 0.21 in the EUV (500-1000 A). The COS EUV index is similar to that of radio-quiet AGN in the 2002 HST/FOS survey (alpha_nu = -1.57 +/- 0.17). We see no Lyman edge (tau_HI < 0.03) or He I 584 emission in the AGN composite. Our 22 AGN exhibit a substantial range of FUV/EUV spectral indices and a correlation with AGN luminosity and redshift, likely due to observing below the 1000 A break.

description: Building biological models by inferring functional dependencies from experimental data is an important issue in Molecular Biology. To relieve the biologist from this traditionally manual process, various approaches have been proposed to increase the degree of automation. However, available approaches often yield a single model only, rely on specific assumptions, and/or use dedicated, heuristic algorithms that are intolerant to changing circumstances or requirements in the view of the rapid progress made in Biotechnology. Our aim is to provide a declarative solution to the problem by appeal to Answer Set Programming (ASP) overcoming these difficulties. We build upon an existing approach to Automatic Network Reconstruction proposed by part of the authors. This approach has firm mathematical foundations and is well suited for ASP due to its combinatorial flavor providing a characterization of all models explaining a set of experiments. The usage of ASP has several benefits over the existing heuristic algorithms. First, it is declarative and thus transparent for biological experts. Second, it is elaboration tolerant and thus allows for an easy exploration and incorporation of biological constraints. Third, it allows for exploring the entire space of possible models. Finally, our approach offers an excellent performance, matching existing, special-purpose systems.

description: This paper presents the frequency dependence of the spin current emission in a hybrid ferrimagnetic insulator/normal metal system. The system is based on a ferrimagnetic insulating thin film of Yttrium Iron Garnet (YIG, 200 nm) grown by liquid-phase-epitaxy (LPE) coupled with a normal metal with a strong spin-orbit coupling (Pt, 15 nm). The YIG layer presents an isotropic behaviour of the magnetization in the plane, a small linewidth, and a roughness lower than 0.4 nm. Here we discuss how the voltage signal from the spin current detector depends on the frequency [0.6 - 7 GHz], the microwave power, Pin, [1 - 70 mW], and the in-plane static magnetic field. A strong enhancement of the spin current emission is observed at low frequencies, showing the appearance of non-linear phenomena.

description: We discuss the unitary quantum dynamics of the Dicke model (spin and oscillator coupled). A suitable quasiprobabilty representing the quantum state turns out to obey a Fokker-Planck equation, with drift terms representing the underlying classical Hamiltonian flow and diffusion terms describing quantum fluctuations. We show (by projecting the dynamics onto a co-moving Poincaré section) how the interplay of deterministic drift and quantum diffusion generates equilibration to the microcanonical density, under conditions of global classical chaos. The pertinent photon statistics reveals macroscopic quantum fluctuations.

description: This supporting paper provides the chronological background development in relation to my studio practice, as an international student, an Iranian female artist, a newcomer to Canada, a dreamer, and a traveller, who is experiencing living in two cultures simultaneously. This paper contains reflective statements, critical statements, and a visual and written narrative about my journey of living in between places, moments, multiple identity constructions, and mixed language identities. In this paper, I have a thematic approach to each exhibition I installed throughout my two-year MFA program at the Department of Art at University of Calgary. I am a traveller who starts her story by narrating her personal perspective on the spatial changes in her life, displacement of identities and places, and her second language identity as a result of migration. In my research creation process, I constantly raise questions such as: How can I picture the sentiment of wavering between two simultaneous realities? How can I express the consequences of being ‘present’ in two separate cultures at once? How can I embody the swings in multiple added layers and fragments of my identity and their relation to place? And how can I address the notion of searching for the perception of belonging, while I am undergoing living and being in-between? My endeavour is to contextualize and articulate my creative research in a cohesive and clear way. I ask my reader to walk with me in every phase of this effort and experience part of my journey.

Year: 2019

description: Preference handling and optimization are indispensable means for addressing nontrivial applications in Answer Set Programming (ASP). However, their implementation becomes difficult whenever they bring about a significant increase in computational complexity. As a consequence, existing ASP systems do not offer complex optimization capacities, supporting, for instance, inclusion-based minimization or Pareto efficiency. Rather, such complex criteria are typically addressed by resorting to dedicated modeling techniques, like saturation. Unlike the ease of common ASP modeling, however, these techniques are rather involved and hardly usable by ASP laymen. We address this problem by developing a general implementation technique by means of meta-prpogramming, thus reusing existing ASP systems to capture various forms of qualitative preferences among answer sets. In this way, complex preferences and optimization capacities become readily available for ASP applications.

description: This study revealed that there are significant challenges to a superintendent’s and principals’ ability to effectively practice instructional leadership. These challenges to instructional leadership are categorized into five themes: vision/mission; teaching and planning time; managing classroom instruction; student success/progress; and positive atmosphere. Of these five themes the superintendent and principals effectively demonstrated instructional leadership except in the area of student success/progress. More focused attention and professional development is required in this area. Dealing with emergent issues, ensuring stakeholder input, working with reluctant staff members, financial limitations, and accountability requirements were found to be the most significant challenges to instructional leadership practices. This exploratory case study was conducted using semi-structured interviews and document analysis to collect data. The units of analysis were a superintendent, fifteen principals, and sixteen teachers from a high performing school district in Alberta. This study also describes eight recommendations related to superintendent and principal instructional leadership practices and five suggestions for future research. Recommendations for policy-makers (reduce the number and scope of accountability requirements), superintendents and principals (developed a comprehensive school district strategic plan), trustees and community stakeholders (provide training to ensure that roles and responsibilities are understood), and superintendent and principal preparation programs (establish mentoring and support) are specifically mentioned.

description: The paper considers the problem of estimating the parameters in a continuous time regression model with a non-Gaussian noise of pulse type. The noise is specified by the Ornstein-Uhlenbeck process driven by the mixture of a Brownian motion and a compound Poisson process. Improved estimates for the unknown regression parameters, based on a special modification of the James-Stein procedure with smaller quadratic risk than the usual least squares estimates, are proposed. The developed estimation scheme is applied for the improved parameter estimation in the discrete time regression with the autoregressive noise depending on unknown nuisance parameters.

description: In analogy to the Coulomb and the Pauli spin blockade, based on the electrostatic repulsion and the Pauli exclusion principle respectively, the concept of valley blockade in Silicon nanostructures is explored. The valley parity operator is defined. Valley blockade is determined by the parity conservation of valley composition eigenvectors in quantum transport. A Silicon quantum changeover switch based on a triple of donor quantum dots capable to separate electrons having opposite valley parity by virtue of the valley parity conservation is proposed. The quantum changeover switch represents a novel kind of hybrid quantum based classical logic device.

description: This dissertation characterizes the role of a small heat shock protein called alphaB-crystallin (αBC) in peripheral nerve regeneration. Peripheral nerve injuries are fairly common and often result in patient disability due to the partial and incomplete regeneration of nerves. The expression of αBC in the peripheral nervous system (PNS) has been known, but its role has not been determined. Because many protective and beneficial functions of the heat shock protein has been reported in a variety of cells and models, I explored whether αBC also has a beneficial role in the PNS particularly after sustaining an injury. Using 129S6 wild-type (WT) and αBC null (αBC-/-) mice, I discovered that αBC positively influenced PNS regeneration. Following sciatic nerve crush, I found that αBC-/- mice had decreased functional recovery, slower motor nerve conduction velocities, and thinner myelin sheaths 28 days post-injury. I additionally observed higher numbers of macrophages (mΦ) in the distal sciatic nerves of αBC-/- mice during the late time points post-injury that may explain the heightened sensitivity towards mechanical and thermal stimulation observed in these animals. I further elucidated that the injury deficits observed in the αBC-/- mice were due to aberrant neuregulin-1/ErbB2 and pAkt signaling. Cumulatively, these findings indicate that αBC positively modulates peripheral nerve regeneration by promoting remyelination and mediating clearance of macrophages in the distal nerve. Lastly, because of reduced expression of αBC with increasing age, I investigated whether αBC plays a role in deficits associated with the aging PNS. I found that αBC-/- mice displayed thinner myelin sheaths before and after injury at different ages. Moreover, 12-month-old αBC-/- mice displayed higher numbers of macrophages before and after injury and, lower numbers of squalene monooxygenase (SQLE), an important enzyme in cholesterol synthesis. These findings are consistent with previous reports that revealed in the aging PNS there is upregulation of genes associated with inflammation and downregulation of genes associated with lipid metabolism. Further exploration is needed to identify the mechanisms involved. Collectively, the work presented in this dissertation provides novel evidence of the significant roles of αBC following peripheral nerve injury.
Effect of organoclay reinforcement on pyrolytic-lignin-based carbon fibres
Creators: name: Qin, Wei

description: Pyrolytic lignin has negative effect on the quality of bio-oil in the application as fuel and energy source. On the other hand, pyrolytic lignin is also a potential alternative precursor for the manufacturing of general performance grade carbon fibre. Since clay or layered silicate reinforcement has been demonstrated to enhance the mechanical properties of many polymers, improvement of mechanical properties of carbon fibre fabricated in this work is expected. This thesis focuses on the proof-of-concept study of pyrolytic-lignin-based carbon fibres and investigates the potential of organoclay reinforcement in improving the mechanical properties of the resultant carbon fibres. In the process of carbon fibre preparation, the pretreatment (thermal treatment under reduced pressure) was found to be a critical step in the successful preparation of carbon fibres from pyrolytic lignin. Without pretreatment, the pyrolytic lignin tended to develop hollow structures during spinning and the spun fibres fuse when thermostabilized. In the pretreatment, higher temperatures and longer time (170-180oC and 4-6 hrs) led to poor fibre spinning of pyrolytic lignin, whereas lower temperature and shorter time (150oC and 0.5-2 hrs) resulted in lignin fibres fusing in the thermostabilization process. Only a narrow window between these two extremes is suitable for carbon fibre production. By choosing the treatment condition (160°C, 30KPa for 1h) that gives the best fibre spinning, pyrolytic-lignin-based carbon fibres were fabricated, with mechanical properties and yield comparable to those based on technical lignins. Two organoclays were employed containing modifiers with different hydrophobicity. The tensile strength of carbon fibres were improved by 12% to ~440 MPa at a 1 wt% organoclay Cloisite 30B loading. Increasing the organoclay content above 1 wt% resulted in a drop in tensile strength. The Young's modulus of pyrolytic-lignin-based carbon fibres dropped slightly upon addition of both types of organoclays (~32 GPa) and decreased as organoclay content increases. The addition of organoclay only slightly increased the overall yield of carbon fibre production from 45 wt% to 46-47%, which was independent of organoclay type and loading.

subject: Chronic Kidney Disease

description: The research focus is to investigate the lived experience of moral distress for registered nurses who care for patients with chronic kidney disease. Incidence of chronic kidney disease is growing in Canada, and retaining skilled nephrology nurses is essential. As the disease progresses, and the patient and family suffer losses, the nurse accompanies them on their journey. The concept of moral distress has been investigated within several areas of nursing but there are few research studies focusing solely on nephrology. Guided by the philosophy of Husserl with analysis supported by Giorgi’s method, constituents and essences were rendered from the findings. The relational ethics theory was used as a structural framework. The purpose of this research is to extend a voice to nephrology nurses, and contribute to a moral community. The findings from this research will offer a thematic structure for understanding the lived experience of moral distress for nephrology nurses.

description: We study role of the Hall diffusion in the magnetic star-disc interaction. In a simplified steady state configuration, the total torque is calculated in terms of the fastness parameter and a new term because of the Hall diffusion. We show the total torque reduces as the Hall term becomes more significant. Also, the critical fastness parameter (at which the total torque is zero) reduces because of the Hall diffusion.

description: Roadway construction work zone imposes travel delay on the road users. The monetary cost of the delay is called user delay cost (UDC). Limited work has been done on quantifying UDC in Canada and their focus were rural highways. If there is a realistic estimate of UDC, it could lead to less schedule overruns and more cost-effective work zone layouts. Considering interest of roadway agencies in quantifying UDC associated with urban arterial work zones, this research developed a probabilistic tool for monetizing UDC in urban setting using traffic microscopic simulation and Monte-Carlo simulation. Based on this tool, one hour of morning peak construction work on NB Crowchild Bridge created 169.2 hr of vehicles delay with average and 95 percentile UDC equal to $2,199 and $5,653, respectively. The application of the tool for selecting optimum work zone layout was demonstrated using the data from the rehabilitation of Bow Bridge in Calgary.
Rapid prototyping of microfluidic devices for culture of suspended cell sheets

Subjects: Biology--Cell

description: Embryogenesis is not only interesting as a research base perspective but also from applied tissue engineering point of view because this is how tissues are created naturally. In only a few days, a mammalian fertilized egg undergoes cell divisions and subsequent reorganization to progress through morula and then blastocyst. Some cells of the inner cell mass give rise to a surface layer known as primitive endoderm, and the others epithelialize to form the epiblast layer. This epiblast cell layer, pluripotent tissue, then undergoes gastrulation to develop all tissues and organs of the embryo. As these stages of development are not accessible in many organisms due to ethical and practical challenges, the bulk of our understanding is derived from mice. Therefore, an in vitro model is needed to replicate in vivo structure and microenvironment and study pre-implantation mammalian development in a physiologically relevant form. Overall, we could rapidly prototype a microfluidic platform in an easy, fast and low-cost manner that allows us to control concentration gradients of relevant signals over selected positions of suspended cell sheet, where there is a need. As we aimed to make microfluidic fabrication more accessible to biology labs with no expertise in microfluidic field, this work also led to an easy-to-use kit to make microfluidics available to non-experts. We could also successfully teach this technique to graduate students, professionals at the university level, and younger students (grade 6-8) at summer camp. Cell sheet formation was successful to some extent using an artificial extracellular matrix, StemAdhere, however, these suspended cell sheets could not resist the compression caused by clamping the device.

description: For relativistic quantum field theories, we consider Lorentz breaking, spatially homogeneous field configurations or states that evolve in time along a symmetry direction. We dub this situation "spontaneous symmetry probing" (SSP). We mainly focus on internal symmetries, i.e. on symmetries that commute with the Poincare group. We prove that the fluctuations around SSP states have a Lagrangian that is explicitly time independent, and we provide the field space parameterization that makes this manifest. We show that there is always a gapless Goldstone excitation that perturbs the system in the direction of motion in field space. Perhaps more interestingly, we show that if such a direction is part of a non-Abelian group of symmetries, the Goldstone bosons associated with spontaneously broken generators that do not commute with the SSP one acquire a gap, proportional to the SSP state's "speed". We outline possible applications of this formalism to inflationary cosmology.

description: This study examines the relation between social skills and emotional intelligence in adolescents with High Functioning Autism Spectrum Disorder following completion of the Program for the Education and Enrichment of Relational Skills (PEERS; Laugeson & Frankel, 2010). PEERS is a 14-week manualized, caregiver-assisted, evidence-based social skills intervention for adolescents designed to teach the skills required to develop and maintain meaningful relationships. Measures of social skills and emotional intelligence were examined one week prior to participation in PEERS (T1), one week after (T2), and 16 weeks following completion of PEERS (T3). Results indicate significant improvements in social skills and overall emotional intelligence from T1 to T2. A significant positive correlation between social skills and emotional intelligence was found at T1 and T2 for self-report, but caregiver-reported social skills and emotional intelligence were only significant at T1. Additionally, poor reliability of change scores prevented the prediction of social skills from emotional intelligence.
Causal Inference: Additive Hazard Model for Mediation Analysis with Measurement Error and Marginal Structural Models

Subjects: subject: Statistics

description: In epidemiologic and social science studies, researchers are often interested in understanding the causal effect from an exposure variable to an outcome variable. In this thesis, we develop two different models and methods to conduct causal inference: (1). causal mediation analysis under the additive hazards model with exposure-mediator interaction; (2). marginal structural additive hazards model. The existing literature requires accurate measurements of the mediator and the confounders, which could be infeasible in biomedical studies. Furthermore, the current identification results of causal effects under the additive hazards model do not allow for exposure-mediator interaction. In this thesis, we derive identification results of causal effects under the additive hazards model with exposure-mediator interaction. Furthermore, we propose consistent measurement error correction methods in the absence/presence of exposure-mediator interaction. In the second part of the thesis, we propose a marginal structural additive hazards model. We develop an estimation method for the marginal structural additive hazards model and apply the simulation-extrapolation (SIMEX) method to correct for the bias resulting from measurement error.
