description: Современная глобальная экономическая парадигма характеризуется усилением роли инноваций в создании условий устойчивого экономического роста. В данной ситуации использование таких экономических показателей, как ВВП, фокусирующиеся на темпах и объемах производства, для формирования объективного представления о сильных и слабых сторонах национальных экономик становится недостаточным. Игнорирование базового условия инновационной деятельности - достаточно высокого уровня человеческого капитала - приводит к ложным интерпретациям экономической действительности. По этой причине сегодня в рамках оценки национальной конкурентоспособности становится очевидной необходимость в поиске новых показателей роста благосостояния населения, фокусирующихся на различных аспектах человеческого потенциала, включая готовность к использованию инноваций. В данной статье предпринимается попытка определить ключевые международные рейтинги и индексы, чьи индикаторы могли бы лечь в основу такой оценки.
Mechanics and dynamics of line boring operation with process damping effect
Creators: name: Aygün, Adem
Publisher: name: University of British Columbia
Year: 2010

description: Rotating shafts are used in the power train components of aircraft and automotive engines. The shafts are turned on lathes. Engine cylinders and bearing housings are finish machined using boring bars with single or multiple inserts. The cutting forces excite the structural dynamics of the turned shafts or boring bars during machining, leading to a poor surface finish and possible damage to the machined parts. This thesis presents mathematical models of single and multiple point turning/boring operations with the aim of predicting their outcome ahead of costly physical trials on the shop floor. Turning and boring operations are conducted at low angular speeds where the system dynamics is dominated by the process damping mechanism. The dynamic forces are modeled proportional to the static and regenerative chip thickness, tool geometry, and velocities of the vibration. The process damping coefficients, which are dependent on the material, tool geometry, cutting speed and vibrations, are identified from chatter tests conducted at the critical speeds and depths. The structural dynamics of the long boring bars are modeled using the Timoshenko Beam elements in Finite Element model which allows parametric placement of the boundary conditions, such as the bearing supports. The dynamics of the interaction between the cutting process and the structure are modeled. The stability of the operations is solved in frequency domain, analytically when the velocity and vibration dependent process damping is neglected. When the process damping is included, but the periodicity of the dynamic forces is neglected, the stability of the process is solved using the Nyquist criterion. When the periodicity and process damping are considered, the dynamic system is represented by a set of differential equations with periodic, time delayed forces. The stability of such systems, which are found in the line boring of crank and cam shaft housings, is solved in the time domain using an analytical but semi-discrete method. The thesis presents a complete set of solutions in predicting the static and dynamic forces, as well as the critical depths of cuts and speeds to avoid chatter vibrations in single point, multi-point and line boring operations.

description: The information causality principle is a generalisation of the no-signalling principle which implies some of the known restrictions on quantum correlations. But despite its clear physical motivation, information causality is formulated in terms of a rather specialised game and figure of merit. We explore different perspectives on information causality, discussing the probability of success as the figure of merit, a relation between information causality and the non-local `inner-product game', and the derivation of a quadratic bound for these games. We then examine an entropic formulation of information causality with which one can obtain the same results, arguably in a simpler fashion.

description: We report a bipolar field effect tunneling transistor that exploits to advantage the low density of states in graphene and its one atomic layer thickness. Our proof-of-concept devices are graphene heterostructures with atomically thin boron nitride acting as a tunnel barrier. They exhibit room temperature switching ratios ~50, a value that can be enhanced further by optimizing the device structure. These devices have potential for high frequency operation and large scale integration.
Bifurcation along curves for the p-Laplacian with radial symmetry

description: We study the global structure of the set of radial solutions of a nonlinear Dirichlet problem involving the p-Laplacian with p>2, in the unit ball of $R^N$, $N \ges 1$. We show that all non-trivial radial solutions lie on smooth curves of respectively positive and negative solutions and bifurcating from the line of trivial solutions. This involves a local bifurcation result of Crandall-Rabinowitz type, and global continuation arguments relying on monotonicity properties of the equation. An important part of the analysis is dedicated to the delicate issue of differentiability of the inverse p-Laplacian. We thus obtain a complete description of the global continua of positive/negative solutions bifurcating from the first eigenvalue of a weighted, radial, p-Laplacian problem, by using purely analytical arguments, whereas previous related results were proved by topological arguments or a mixture of analytical and topological arguments. Our approach requires stronger hypotheses but yields much stronger results, bifurcation occuring along smooth curves of solutions, and not only connected sets.

description: We establish the time decay rates of the solutions to the Cauchy problem for the two-species Vlasov-Poisson-Boltzmann system near Maxwellians via a refined pure energy method. The negative Sobolev norms are shown to be preserved along time evolution and enhance the decay rates. The total density of two species of particles decays at the optimal algebraic rate as the Boltzmann equation, but the disparity between two species and the electric field decay at an exponential rate. This phenomenon reveals the essential difference when compared to the one-species Vlasov-Poisson-Boltzmann system in which the electric field decays at the optimal algebraic rate or the Vlasov-Boltzmann system in which the disparity between two species decays at the optimal algebraic rate. Our proof is based on a family of scaled energy estimates with minimum derivative counts and interpolations among them without linear decay analysis, and a reformulation of the problem which well displays the cancelation property of the two-species system.

description: Observations are revealing the ubiquity of filamentary structures in molecular clouds. As cores are often embedded in filaments, it is important to understand how line profiles from such systems differ from those of isolated cores. We perform radiative transfer calculations on a hydrodynamic simulation of a molecular cloud in order to model line emission from collapsing cores embedded in filaments. We model two optically thick lines, CS(2-1) and HCN(1-0), and one optically thin line, N2H+(1-0), from three embedded cores. In the hydrodynamic simulation, gas self-gravity, turbulence, and bulk flows create filamentary regions within which cores form. Though the filaments have large dispersions, the N2H+(1-0) lines indicate subsonic velocities within the cores. We find that the observed optically thick line profiles of CS(2-1) and HCN(1-0) vary drastically with viewing angle. In over 50% of viewing angles, there is no sign of a blue asymmetry, an idealised signature of infall motions in an isolated spherical collapsing core. Profiles which primarily trace the cores, with little contribution from the surrounding filament, are characterised by a systematically higher HCN(1-0) peak intensity. The N2H+(1-0) lines do not follow this trend. We demonstrate that red asymmetric profiles are also feasible in the optically thick lines, due to emission from the filament or one-sided accretion flows onto the core. We conclude that embedded cores may frequently undergo collapse without showing a blue asymmetric profile, and that observational surveys including filamentary regions may underestimate the number of collapsing cores if based solely on profile shapes of optically thick lines.

description: We report a new analysis of lattice simulation results for octet baryon masses in 2+1-flavor QCD, with an emphasis on a precise determination of the strangeness nucleon sigma term. A controlled chiral extrapolation of a recent PACS-CS Collaboration data set yields baryon masses which exhibit remarkable agreement both with experimental values at the physical point and with the results of independent lattice QCD simulations at unphysical meson masses. Using the Feynman-Hellmann relation, we evaluate sigma commutators for all octet baryons. The small statistical uncertainty, and considerably smaller model-dependence, allows a signifcantly more precise determination of the pion-nucleon sigma commutator and the strangeness sigma term than hitherto possible, namely σπN=45 \pm 6 MeV and σs = 21 \pm 6 MeV at the physical point.

description: The concrete biosand filter (BSF) is a viable household water treatment option. CAWST is a non-profit organization that trains local organizations to build, install, and operate BSFs. The objective of this study was to develop and pilot a quality control workshop to support decentralized production of high quality filters. The workshop was evaluated using the Kirkpatrick model. The overall reaction and reported learning to the workshop was positive. The slump test emerged as a viable quality control test. To formulate slump test recommendations, it was desired to optimize the water-to-cement ratio and curing method. Wet curing resulted in 17.3% stronger concrete than dry curing. Dry curing resulted in 0.06% shrinkage after 28 days (p<0.0001). Water-to-cement ratio did not affect shrinkage (p = 0.69) but had a significant effect (p < 0.0001) on the strength. The optimal range for the water-to-cement (mass) was 0.51 – 0.59, or 8.0 L– 9.3 L water/filter.

description: During pregnancy, pancreatic β-cells adapt to the increase in maternal insulin resistance by up-regulating β-cell mass, insulin synthesis, and lowering glucose-stimulated insulin secretion threshold. Signaling through prolactin receptor (PrlR) is critical for these adaptive responses. We hypothesize that PrlR present on β-cells are the primary determinant of β-cell adaptation to pregnancy. We found that β-cell specific deletion of PrlR in mice leads to higher fasted blood glucose and impaired glucose tolerance in comparison with wild type mice. Furthermore, we identified Lrrc55 (leucine rich repeat containing 55), an auxiliary subunit of BK channels as one of the potentially novel targets of PrlR. Results suggest that Lrrc55 overexpression protected INS-1 cells from H2O2, high glucose, palmitate, and high glucose+palmitate-induced apoptosis by attenuating ER stress and intrinsic apoptosis pathways and also maintaining healthy ER calcium reserves. Taken together, this study helps unravel components of PrlR signaling as possible therapeutic strategy to treat diabetes.
Music lessons : a cultural studies analysis of music's capacity for critical pedagogy and methodology
Creators: name: Hunt, L. A. Pearl
Publisher: name: University of British Columbia
Year: 2010

description: When expressing the phrase music lessons, one often visualizes students with their musical instruments practicing scales or compositions with the intent of memorizing the music. Although music can actualize as mnemonic practice, this dissertation focuses on other lessons that music teaches us by examining how musical knowledge is produced. Building on the ideologies articulated within a framework of cultural studies, the dissertation attempts a pedagogical praxis that establishes a fluid and dynamic conversation to express both my theoretical and empirical findings. The findings then are not definitive answers to the questions I pose about music’s effect, but operate as a process of opening up these questions to further reflection. The dissertation, by invoking a praxis-based structure, communicates both the theoretical “how” of music as praxis involved work and my practice of realizing music as culture-in-action. The dissertation aims to redress music – not only in terms of music making as transformative praxis but also to assert that music, as a means of producing knowledge within critical discourse, can be situated as the subject versus the object of effect. Because a core component of music is its ability to be inclusive of all cultures/peoples, the dissertation examines how the performative aspects of music intersects sites and people of differing class, gender, race and culture to articulate music’s capacity for negotiating difference. Pitched in this way, music can no longer be regarded by critical educators as being on the sidelines of critical discourse but rather will be seen as integral to transforming consciousness and realizing praxis. By informing and expanding upon the theory and practice of critical pedagogy, this music discourse not only seeks to influence a broader idea of social justice praxis but can also operate as a predominant cultural component in promoting peace education.

The equation of state parameter has exhibited quintessence-like behavior and from the plot of the deceleration parameter we have observed an ever accelerating universe.
Near-surface S-wave traveltime corrections and inversion: a raypath-consistent and interferometric approach

description: Removing near-surface effects in the processing of 3C data is key to exploiting the information provided by converted waves, particularly for the case of the PS mode where converted energy travels back to the surface as S-waves. The very low velocity of S-waves amplifies the distortions introduced by the near-surface in the PS-traveltimes. This is usually solved by computing the vertical traveltimes in the near-surface layer and removing them from the data in a surface-consistent framework. However, if the velocity change between the near-surface layer and the medium underneath is small, the vertical raypath assumption that supports the surface-consistent approach is no longer valid. This property results in a non-stationary change of the near-surface traveltimes that needs to be addressed to properly remove its effect. I show how the delays introduced by the presence of very low S-wave velocities in the near-surface can introduce raypath-dependent effects which can be larger than what can be considered a residual static. In this study, a raypath-consistent solution for removing near-surface traveltime effects is proposed. This is achieved by transforming the data, organized into receiver gathers, to the tau-p domain and performing crosscorrelation and convolution operations to capture and remove the near-surface delays from the data. The tau-differences captured during the interferometric processing of the near-surface effects are then used in an inversion algorithm to estimate the S-wave velocities in the near-surface. This processing work-flow provides not only a set of corrections but also a velocity model that is based on them. I tested this method on synthetic and field data. In both cases, removing near-surface time delays in a raypath-consistent framework improved coherency and stacking power of shallow and deep events simultaneously. Shallow events benefited most from this processing due to their wider range of reflection angles. This approach can be useful in the processing of wide-angle broadband data, where the kinematics of wave propagation are not consistent with vertical raypath approximations in the near-surface. Additionally, this method provides a near-surface S-wave velocity model that can be used for building migration velocity models or to initialize elastic full waveform inversions.

description: The Regge trajectories, upon which string theory is based, behave as rigid rotators rather than vibrating strings. The same relation, between the angular momentum, and the square of the mass, can be found in gravity, the electroweak, and strong interactions. The angle deficit for cosmic strings is shown to be an angle excess that is related to the increase of the circumference of a uniformly rotating disc. Schrödinger's time independent equation with a centrifugal barrier gives an automorphic function that can be constructed as the ratio of its two independent solutions for values of the angular momentum lying outside of their positive, integer values. If the fixed points 0 and $\infty$ in the z-plane correspond to $-i$ and $+i$ in the $ω$-plane, then elliptic substitutions tessellate the $ω$-plane in the form of cresents, while if the fixed points correspond to -1 and +1 in the $ω$-plane are source and sink, just like the lines of force between positive and negative charges. The unit disc undergoes a stretching by a Lorentz transform.

An Investigation of the Role of Low Frequencies in Seismic Impedance Inversion

description: Acoustic seismic impedance inversion is investigated using a migrated, stacked, reflectivity image. Basic inversion formulae are derived and sensitivity to the bandwidth of the reflectivity is analyzed. It is shown that high frequencies are responsible for the detail in the impedance image and low frequencies are responsible for the trend, where the low frequencies must be acquired from an external data type. External data must be matched to the reflectivity image. Methods for data amplitude balancing and phase rotation are discussed. A Hilbert envelope calibration algorithm is designed to calibrate the time-depth curves between the seismic reflectivity and the external data. Both the use of well logs and stacking impedances are explored, and while well logs produce the most accurate images, a combination of the two types is also acceptable. Inversions are sensitive to the amount of external data that is added and reliable impedance images can be produced by using just 1.5-2.5 Hz of the external data.
The Impact of Resistance on Line Loadability when Selecting Transmission Lines for Dynamic Thermal Line Rating

description: With increased focus on renewable generation, new ways to maximize the existing capacity of an electrical grid are being investigated. One method is to increase the transmission line capacity by using dynamic thermal line rating, or DTLR. One problem facing widespread implementation of DTLR is how to select which transmission lines would benefit most from DTLR installation. Traditionally, DTLR is only applied to transmission lines that are thermally rated. This thesis expands this notion by considering the relationship between conductor temperature and resistance to increase the rating of longer lines (over 80 km) that are not thermally limited. This thesis also determines which transmission lines are suitable for DTLR, based on the maximum thermally limited line length, and investigates how this length changes when DTLR is applied. This thesis then combines the two methods for DTLR to demonstrate the capacity increase for all lengths of transmission lines.
N-player quantum games in an EPR setting

description: The $N$-player quantum game is analyzed in the context of an Einstein-Podolsky-Rosen (EPR) experiment. In this setting, a player's strategies are not unitary transformations as in alternate quantum game-theoretic frameworks, but a classical choice between two directions along which spin or polarization measurements are made. The players' strategies thus remain identical to their strategies in the mixed-strategy version of the classical game. In the EPR setting the quantum game reduces itself to the corresponding classical game when the shared quantum state reaches zero entanglement. We find the relations for the probability distribution for $N$-qubit GHZ and W-type states, subject to general measurement directions, from which the expressions for the mixed Nash equilibrium and the payoffs are determined. Players' payoffs are then defined with linear functions so that common two-player games can be easily extended to the $N$-player case and permit analytic expressions for the Nash equilibrium. As a specific example, we solve the Prisoners' Dilemma game for general $ N \ge 2 $. We find a new property for the game that for an even number of players the payoffs at the Nash equilibrium are equal, whereas for an odd number of players the cooperating players receive higher payoffs.

description: The purpose of this qualitative case study of an urban school district in southern Alberta was to examine the role of school leaders in supporting the development of teacher beliefs and practices to foster critical thinking by students. In Alberta, this is particularly relevant to school leaders who are required to support teachers to implement the Ministerial Order on Student Learning (Alberta Education, 2013) requirement that students think critically across subject and discipline areas for learning, work, and life. The literature review examined definitions, development, and educational significance of critical thinking by all children. Current research concerning the relationship between teacher beliefs and teacher practices to foster critical thinking was explored. Leadership practices to support teacher change were surveyed, with a focus on setting clear goals and expectations, involvement in instructional programming, and promoting and participating in a positive school learning climate. Qualitative questionnaires, classroom observations, semi-structured interviews, focus group discussion, and document review methods were used to collect data and examine the phenomenon from multiple perspectives. Findings indicated that while teachers believe fostering critical thinking is an important goal of education, they believe some students are less able to benefit from critical thinking opportunities. Teachers and school leaders identified supportive leadership practices to help develop teacher beliefs and practices to foster critical thinking by students. The twelve findings are synthesized to provide meaningful recommendations for school leaders and for future research.

This study determined the incidence of CDI in Alberta, investigated risk factors associated with mortality amongst Alberta CDI patients, and investigated the inter-rater reliability between the Death Attribution Rules for Patients Infected by C. difficile (DARPIC) algorithm and IPC physicians. Incidence of CDI in Alberta hospitals, continuing care facilities, and the community provided a comprehensive understanding of CDI in Alberta. Although CDI is predominantly a nosocomial infection, 47% of the CDI cases identified in this study occurred in the community. Risk factors for mortality amongst hospitalized CDI patients were increasing age and comorbidity count, liver disease, and metastatic solid tumour. Attributing death to CDI is difficult and opinions vary by clinicians, to accurately and consistently report attributable CDI mortality a standardized approach is necessary.

Secondary School Counsellor Stress and Strategies to Cope
Creators: name: Lidster, Susan

Year: 2015
Subjects: subject: Education--Guidance and Counseling
subject: Counsellor

description: This qualitative, action research study was designed to examine the sources and effects of job-related stress for school counsellors and the strategies that may be used to minimize them. This study aimed to illuminate the work environment of school counsellors and the impact this may have on the students they serve. An on-line survey was developed and was completed by practicing school counsellors in School District #73 (Kamloops/Thompson), which provided insight into their perception of these issues. The findings from this study suggest that the participants experienced these job-related stressors: dealing with critical incidents, insufficient time to complete all required tasks, a lack of understanding of the role of the school counsellor by other stakeholders, work overload caused by staff reduction, and the inability to meet all of the needs of students. Peer support, positive self-care, and professional development opportunities related to job-related stress management were strategies that some school counsellors used to minimize the negative effects of job-related stress. Additionally, the findings show that school counsellors believed school and district administrators play a role in determining their role and improving their work environment. Practical recommendations to address the sources and effects of job-related stress for school counsellors in response to the collected data include: the development, in conjunction with other education stakeholders, of a clearer definition of the roles of school counsellors, the potential development of a provincial or a national model for school counsellors in Canada, and the creation of partnerships with practising school counsellors and educational leaders responsible for developing and implementing curriculum for school counsellor training programmes. These findings may be of interest to all educational stakeholders.
Knowledge is Power: Examining the Association Between Parents’ Knowledge of Attention- Deficit/Hyperactivity Disorder (ADHD), Parenting Stress, and Symptoms of Child Anxiety

description: This study investigated the roles of parents’ knowledge of ADHD and parenting stress on symptoms of anxiety in children with and without ADHD aged 8 to 12 years. Thirty-nine parent-child dyads from Calgary and Toronto were studied, with 21 dyads in an ADHD group and 18 dyads in a non-ADHD group. Results overall indicated no significant differences between groups in parents’ knowledge of ADHD scores; however, parenting stress was significantly higher in ADHD than in non-ADHD parents. Parenting stress was not a significant predictor of anxiety symptoms in children with ADHD, and parents’ knowledge of ADHD did not moderate this relationship. Parents’ knowledge of ADHD alone was, however, a significant predictor of anxiety symptoms in children with ADHD. Results of the current study suggest that additional research should focus on parents’ knowledge of ADHD as a possible risk factor for the development of anxiety symptoms in children with ADHD.

Moment densities of super-Brownian motion, and a Harnack estimate for a class of X-harmonic functions

description: This paper features a comparison inequality for the densities of the moment measures of super-Brownian motion. These densities are defined recursively for each $n \ge 1$ in terms of the Poisson and Green's kernels, hence can be analyzed using the techniques of classical potential theory. When $n = 1$, the moment density is equal to the Poisson kernel, and the comparison is simply the classical inequality of Harnack. For $n > 1$ we find that the constant in the comparison inequality grows at most exponentially with $n$. We apply this to a class of $X$-harmonic functions $H^ν$ of super-Brownian motion, introduced by Dynkin. We show that for a.e. $H^ν$ in this class, $H^ν(μ)

description: Seizures and epilepsy are known to alter motor map expression. Seizures also induce severe local brain hypoxia. Antiepileptics are drugs used to controls seizures in patients with epilepsy. Most of these drugs suppress seizures without preventing or reversing epileptogenesis. Therefore, they are preferably called anti-seizure drugs (ASDs). ASDs inhibit neuronal activation and/or suppress synaptic or neuromuscular transmission to control seizures. Although these drugs alter neuronal and neuromuscular function, their effects on motor maps expression have not been explored. The role of ASDs on prevention of severe seizure-induced hypoxia (SISHE) is also unknown. Moreover, a loop diuretic, bumetanide, has shown anticonvulsant activity in neonates and is currently under clinical trials for managing neonatal seizures. Anti-seizure activity of bumetanide are thought to be through reversing GABA depolarizing effect in immature neurons, by inhibiting Na+,K+ and Cl- co-transporter (NKCC1) which is the cellulullar chloride importer. Furthermore, bumetanide has recently reported to reduce seizure frequency in adult patients. Despite of these facts, study of bumetanide’s effects on motor maps expression is sparse and its role in controlling seizures in adults has not been given attention. In vivo experiments using young adult rats were carried out to determine the effects of several ASDs and bumetanide on motor maps expression. Intracortical microstimulation was done to derive the motor maps both pre- and post-drug application. Young adult rats were kindled and used to investigate the effects of bumetanide on seizure activity, which were measured 30 minutes post-bumetanide intraperitoneal treatment. Furthermore, kindling of rats was done to determine the effects of the ASDs and bumetanide on SISHE. Results showed that ASDs reduces the responsiveness of the motor cortex evidenced by forelimb map hypotrophy and elevated movement thresholds. This study has also demonstrated that bumetanide inhibits seizure activity in matured rats, which implies that anticonvulsant activity of this drug is not exclusively due to blockage of NKCC1. Further findings show that with the exception of ethosuximide which reduced the expression of SISHE, other ASDs and bumetanide neither affected brain oxygen level nor severity of SISHE.

description: We derive the requirements that a generic axion-like field has to satisfy in order to play the role of the inflaton field in the warm inflation scenario. Compared to the parameter space in ordinary natural inflation models, we find that the parameter space in our model is enlarged. In particular, we avoid the problem of having an axion decay constant $f$ that relates to the Planck scale, which is instead present in the ordinary natural inflation models; in fact, our model can easily accommodate values of the axion decay constant that lie well below the Planck scale.

Architecture, computation and nature: living and non-living natural models in computational architecture

description: Inspiration from nature is ever present in art and architecture. The complexity of natural systems results in shrinking and simplifying living or non-living natural models and patterns until they fit under technological capabilities of one point in time. More technology means a deeper understanding of nature. This allows new connections between nature as a tool and as a source of inspiration and imitation and architecture as a product. This thesis discusses and tests the relationship between computation as a tool and the natural world, both as a source of analogy and inspiration and as an instrument in contemporary computational architecture.
 Despite the relationship between programming as an instrument, nature as inspiration and tool and architectural design as a product, fields like computer science, mathematics, biology or physics are underrepresented or only metaphorically represented in the discourse and education on contemporary architecture.
 Using a practical reflective methodology, the thesis investigates how a cultural interest for science in the context of a network society penetrates advanced computational architecture. It also discusses the areas where using a corpus of scientific knowledge is distorted or superficial. The main idea was to highlight types of inspiration and analogy from living and non-living nature in architecture using computation as a tool (and only those that could not have been replicated effectively in any other way).
 The contribution of this research is to fill in small gaps in the discourse on advanced computational architecture and its tools. The contribution in terms of tools include: (1) a plug-in (a library) for the Grasshopper visual programming language which works with Rhino 3D, a NURBs modelling software; (2) a series of projects for which generative tools were developed in orded to produce architectural or artistic projects inspired from living and non-living nature. These tools can can be translated in different contexts. Finally, a methodology and a series of dynamic urban analyses which are alternatives for understanding dynamic cities. The methodology is applied to the city of Cluj-Napoca in Romania.
