Do Leaders Matter? How Personal Characteristics and Experiences Shape Electoral Violence
Creators: name: Akuamoah, Ernest
Publisher: name: The Australian National University
Year: 2023

description: While incumbents' role in electoral violence has received considerable scholarly attention, little is known about how political leaders themselves affect electoral violence. An increasing number of studies have shown that myriad political outcomes can be explained by focusing on leaders' personal attributes and life experiences. This thesis examines how political leaders' decisions and prior experiences affect their use of, or abstinence from, violent electoral strategies. I contend that (1) leaders with military experience, populist leaders, and those that have manipulated presidential term limits are more likely than their peers to resort to electoral violence and (2) leaders who had their university education in Western countries are less likely to employ electoral violence. The empirical results suggest that leaders from rebel backgrounds, populist leaders, and those that have overstayed their constitutionally mandated term limits are positively associated with their government's use of electoral violence. In contrast, the empirical evidence does not support my theoretical expectation that a leader's Western university education decreases the likelihood of electoral violence. Overall, this study's findings offer important insights into leader-specific drivers of electoral violence, and it broadens our understanding of why violence is such a persistent threat to electoral stability.

description: The formalism of the scattering matrix is applied to describe the transmission properties of multilayered structures with deep variations of the refractive index and arbitrary arrangements of the layers. We show that there is an exact analytical formula for the transmission spectrum, which is valid for the full spectral range and which contains only a limited number of parameters for structures satisfying the quarter-wave condition. These parameters are related to the poles of the scattering matrix, and we present an efficient algorithm to find them, which is based on considering the ray propagation inside the structure and subsequent application of the harmonic inversion technique. These results are significant to analyze the reshaping of ultrashort pulses in multilayered structures.

description: We study regularity of bound states pertaining to embedded eigenvalues of a self-adjoint operator $H$, with respect to an auxiliary operator $A$ that is conjugate to $H$ in the sense of Mourre. We work within the framework of singular Mourre theory which enables us to deal with confined massless Pauli-Fierz models, our primary example, and many-body AC-Stark Hamiltonians. In the simpler context of regular Mourre theory our results boils down to an improvement of results obtained recently in \cite{CGH}.

description: A three dimensional (3D) tomographic reconstruction of the local differential emission measure (LDEM) of the global solar corona during the whole heliosphere interval (WHI, Carrington rotation CR-2068) is presented, based on STEREO/EUVI images. We determine the 3D distribution of the electron density, mean temperature, and temperature spread, in the range of heliocentric heights 1.03 to 1.23 Rsun. The reconstruction is complemented with a potential field source surface (PFSS) magnetic-field model. The streamer core, streamer legs, and subpolar regions are analyzed and compared to a similar analysis previously performed for CR-2077, very near the absolute minimum of the Solar Cycle 23. In each region, the typical values of density and temperature are similar in both periods. The WHI corona exhibits a streamer structure of relatively smaller volume and latitudinal extension than during CR-2077, with a global closed-to-open density contrast about 6% lower, and a somewhat more complex morphology. The average basal electron density is found to be about 2.23 and 1.08 x 10^8 cm^-3, in the streamer core and subpolar regions, respectively. The electron temperature is quite uniform over the analyzed height range, with average values of about 1.13 and 0.93 MK, in the streamer core and subpolar regions, respectively. Within the streamer closed region, both periods show higher temperatures at mid-latitudes and lower temperatures near the equator. Both periods show beta>1 in the streamer core and beta<1 in the surrounding open regions, with CR-2077 exhibiting a stronger contrast. Hydrostatic fits to the electron density are performed, and the scale height is compared to the LDEM mean electron temperature. Within the streamer core, the results are consistent with an isothermal hydrostatic plasma regime, with the temperatures of ions and electrons differing by up to about 10% .. (continues)..

description: The application package "IONORT" for the calculation of ray-tracing can be used by customers using the Windows operating system. It is a program whose interface with the user is created in MATLAB. In fact, the program launches an executable that integrates the system of differential equations written in Fortran and importing the output in the MATLAB program, which generates graphics and other information on the ray. This work is inspired mainly by the program of Jones and Stephenson, widespread in the scientific community that is interested in radio propagation via the ionosphere. The program is written in FORTRAN 77, a mainframe CDC-3800. The code itself, as well as being very elegant, is highly efficient and provides the basis for many programs now in use mainly in the Coordinate Registration (CR) of Over The Horizon (OTH) radars. The input and output of this program require devices no longer in use for several decades and there are no compilers that accept instructions written for that type of mainframe. For this reason, the core of the program to perform numerical integration, after the necessary amendments, was passed to a modern compiler under the Windows operating system and the executable has been imported into a MATLAB program. Thus, all input and output operations are handled by modern MATLAB program that implements the Fortran program and importing the output. This provides great versatility to the entire application package with presentations in two dimensions (2D) and three-dimensional (3D) on real geo-referenced maps.

Vancouver NGOs as agents of settlement program delivery and the financing of immigration policy in Canada
Creators: name: De Luca, Suzanne Jolene
Publisher: name: University of British Columbia
Year: 2016

description: In 1971, Canada undertook a multicultural policy that dignified all Canadians as equal regardless of cultural background. It was a celebration of Canadian diversity. Immigration policy is very important in Canada, as approximately a quarter of a million newcomers make Canada their home every year. Since newcomers are settled into Canada by means of arms length organizations not direct government service delivery, it is important that the service delivery is assessed and continually improved upon. The following research questions will be explored: How are immigrant settlement programs funded in Vancouver? Does this result in issues with their advocacy work? The interviews reveal that the funding structure does result in issues with the advocacy work of settlement organizations. Several recommendations will be provided to improve Vancouver's settlement NGOs.

This result can be of practical relevance for posing some general limits on Eve's eavesdropping process. Finally, we also present a comparison between the bound for antiparallel spins and the bound for parallel spins.

description: We investigate the relation between N=(2,2) superconformal Lie group WZNW models and Lie supergroup WZNW models. The B-twist of an exactly marginal perturbation of the world-sheet superconformal sigma model is the supergroup model. Moreover, the superconformal currents are expressed in terms of Lie superalgebra currents in the twisted theory. As applications, we find protected sectors and boundary actions in the supergroup sigma model. A special example is the relation between string theory on AdS_3 x S^3 x T^4 in the RNS formalism and the U(1,1|2) x U(1|1) x U(1|1) supergroup WZNW model.

The Cooperative Commonwealth Federation and amateur theatricals in 1930's Vancouver, BC

Publisher: name: University of British Columbia
Year: 2016

description: This research investigates a collection of short one-act plays in the Arthur J. Turner Fonds held in the University of British Columbia Rare Books and Special Collections. These plays, written by Arthur J. Turner, Thorvald “Denny” Kristiansen and Hubert Evans in the mid-1930’s, formed part of the Cooperative Commonwealth Federation’s broader social and propaganda efforts to educate and indoctrinate new members in the basic tenets of Socialism and the CCF platform. Like agitprop plays created elsewhere in Canada, Britain and the United States, dramatic groups within CCF clubs wrote and performed such plays as one of many means of legitimization for parties and movements of the Left along with other educational, social and political activities. For the CCF, a recently formed political party built by the merger of many disparate groups and cultures, solidifying their voting base and creating new centres for progressive culture, social gatherings, shared political vision and party solidarity was vital in the 1930’s to ensure the continued existence of the party as well as electoral success and political change. This research seeks to situate these plays amid their social, cultural, historical and political contexts to show that their emergence was a result of the unique set of circumstances created in the Depression-era and a manifestation of the larger global workers’ theatre movement. Finally, this research seeks to recover and publicize the plays of the CCF drama groups that have been almost entirely erased from the broader discourse of Canadian theatre due to their amateur status and exclusion from the hegemonic archive.

description: We present a quasi-conjugate Bayes approach for estimating Generalized Pareto Distribution (GPD) parameters, distribution tails and extreme quantiles within the Peaks-Over-Threshold framework. Damsleth conjugate Bayes structure on Gamma distributions is transfered to GPD. Posterior estimates are then computed by Gibbs samplers with Hastings-Metropolis steps. Accurate Bayes credibility intervals are also defined, they provide assessment of the quality of the extreme events estimates. An empirical Bayesian method is used in this work, but the suggested approach could incorporate prior information. It is shown that the obtained quasi-conjugate Bayes estimators compare well with the GPD standard estimators when simulated and real data sets are studied.

description: This article presents a search for high mass e e or mu mu resonances in pp collisions at sqrt{s} = 7 TeV at the LHC. The data were recorded by the ATLAS experiment during 2010 and correspond to a total integrated luminosity of ~40/pb. No statistically significant excess above the Standard Model expectation is observed in the search region of dilepton invariant mass above 110 GeV. Upper limits at the 95% confidence level are set on the cross section times branching ratio of Z' resonances decaying to dielectrons and dimuons as a function of the resonance mass. A lower mass limit of 1.048 TeV on the Sequential Standard Model Z' boson is derived, as well as mass limits on Z* and E(6)-motivated Z' models.

description: Ratios of azimuthal angle correlations between two jets produced at large rapidity separation are studied in the N=4 super Yang-Mills theory (MSYM). It is shown that these observables, which directly prove the SL(2,C) symmetry present in gauge theories in the Regge limit, exhibit an excellent perturbative convergence. They are compared to those calculated in QCD for different renormalization schemes concluding that the momentum-substraction (MOM) scheme with the Brodsky-Lepage-Mackenzie (BLM) scale-fixing procedure captures the bulk of the MSYM results.

description: The cascade mass reconstruction approach was applied to simulated production of the lightest stop quark at the LHC in the cascade decay $\tilde{g} \to \sTop \, \Top \to \tildeχ_{2}^{0} \, \Top \, \Top \to \tilde{\ell}_{R} \, \ell \, \Top \, \Top \to \tildeχ_{1}^{0} \, \ell \, \ell \, \Top \, \Top$ with top quarks decaying into hadrons. The stop quark mass was reconstructed assuming that the masses of gluino, slepton and of the two lightest neutralinos were reconstructed in advance. A data sample set for the SU3 model point containing 400k SUSY events was generated which corresponded to an integrated luminosity of about 20 $\rm fb^{-1}$ at 14 TeV. These events were passed through the AcerDET detector simulator, which parametrized the response of a generic LHC detector. The mass of the $\tilde{t}_{1}$ was reconstructed with a precision of about $10\%$.

Using ultrasound in Sound Production Treatment for acquired apraxia of speech : a case study of multiple speech sound targets
Creators: name: Murphey, Winifred
Publisher: name: University of British Columbia
Year: 2016

description: Acquired apraxia of speech (AOS) is a disorder of speech production. Treatment approaches and advancements are limited. Technological approaches or additions to current treatment approaches may provide greater benefit to individuals with AOS. This case study examines the effects of treating AOS using an adapted Sound Production Treatment (SPT) hierarchy (Bailey, Eatchel & Wambaugh, 2015) that includes an ultrasound visual feedback component. The goal was to quantify the effects of two speech sound treatment blocks, one using SPT and one using SPT plus Ultrasound (U/S) for a single participant with AOS, and to compare the outcomes from each treatment block with one another. The number of articulatory mismatches for treated and untreated speech sounds were analyzed based on their similarity to the treated speech sounds in terms of phonologic and articulatory features that can be seen on ultrasound. Treated speech sounds showed increases in articulatory accuracy when using SPT with or without ultrasound. This was also true for untreated speech sounds that were maximally phonologically related to the treated speech sounds. Untreated speech sounds that shared articulatory/phonological features visible on ultrasound with the treated speech sounds showed increases in accuracy only in the SPT plus U/S condition. Untreated speech sounds that were minimally phonologically related to the treated speech sounds and were not visible on ultrasound showed limited improvement in either condition These findings suggest that including a visual feedback route in speech treatment for AOS can be used to induce transfer of learning effects to speech sound targets with visibly similar articulatory gesture as those being treated. Clinically, using ultrasound as visual biofeedback in an SPT treatment may be effective in promoting transfer of positive treatment effects to speech sound targets when trained and untrained targets share characteristics observable on ultrasound.

description: We present a study of the impact of different model groups in the detection of circumstellar debris disks. Almost all previous studies in this field have used Kurucz model spectra to predict the stellar contribution to the flux at the wavelength of observation thus determining the existence of a disk excess. Only recently have other model groups or families like Marcs and NextGen-Phoenix become available to the same extent. This study aims to determine whether the predicted stellar flux of a disk target can change with the choice of model family - can a disk excess be present in the use of one model family whilst being absent from another? A simple comparison of Kurucz model spectra with Mrcs and NextGen model spectra of identical stellar parameters was conducted and differences were present at near-infrared wavelengths. Model spectra often do not extend in wavelength to that of observation and therefore extrapolation of the spectrum is required. In extrapolation of model spectra to the Spitzer MIPS passbands, prediction of the stellar contribution differed by 5 % at 70mum for F, G and early K spectral types with differences increasing to 15% for early M dwarfs. Analysis of the Spitzer MIPS 24mum observations of 37 F, G and K solar-like stars in the Pleiades cluster was conducted. In using Kurucz model spectra, 7 disk excesses were detected while only 3 and 4 excesses were detected in using Marcs and NextGen-Phoenix model spectra respectively.

description: Hypothetical influences of variability of light velocity due to the parameters of the source of radiation, for the results of spectral measurements of stars to search for exoplanets are considered. Accounting accelerations of stars relative to the barycenter of the star - a planet (the planets) was carried out. The dependence of the velocity of light from the barycentric radial velocity and barycentric radial acceleration component of the star should lead to a substantial increase (up to degree of magnitude) semi-major axes of orbits detected candidate to extrasolar planets. Consequently, the correct comparison of the results of spectral method with results of other well-known modern methods of detecting extrasolar planets can regard the results obtained in this paper as a reliable test for testing the invariance of the velocity of light.

description: Providing physical-layer security for mobile users in future broadband wireless networks is of both theoretical and practical importance. In this paper, we formulate an analytical framework for resource allocation in a downlink OFDMA-based broadband network with coexistence of secure users (SU) and normal users (NU). The SU's require secure data transmission at the physical layer while the NU's are served with conventional best-effort data traffic. The problem is formulated as joint power and subcarrier allocation with the objective of maximizing average aggregate information rate of all NU's while maintaining an average secrecy rate for each individual SU under a total transmit power constraint for the base station. We solve this problem in an asymptotically optimal manner using dual decomposition. Our analysis shows that an SU becomes a candidate competing for a subcarrier only if its channel gain on this subcarrier is the largest among all and exceeds the second largest by a certain threshold. Furthermore, while the power allocation for NU's follows the conventional water-filling principle, the power allocation for SU's depends on both its own channel gain and the largest channel gain among others. We also develop a suboptimal algorithm to reduce the computational cost. Numerical studies are conducted to evaluate the performance of the proposed algorithms in terms of the achievable pair of information rate for NU and secrecy rate for SU at different power consumptions.

description: A common conception is that the singular focus of home economics educators and home economics education is the development of a technical perspective (technê) in students with the goal of producing a product through reasoned, instrumental action (poïesis). However, taking such a curricular and pedagogical focus reduces the opportunity for interaction with praxis and phronesis. By excluding thoughtful engagement with the topics in this subject area, teachers may unknowingly facilitate mindlessness in themselves and their students regarding everyday life actions, which has the potential to unintentionally propagate harmful ideas and actions. This research is positioned on the idea that attaining a mindful disposition can help educators develop curriculum and pedagogy that challenges students to think critically and, as a result, make thoughtful decisions about their actions in their everyday lives. The home economics curriculum engages with everyday life actions. While they are ‘small’, everyday life actions have the potential to be emancipatory. The purpose of this study is to investigate what non-meditative mindfulness looks like in the practice of a mindful home economics educator and to uncover connections between education, home economics, and mindfulness. Through the use of case study and action research methodology, the research investigates how a home economics teacher engages with and employs mindfulness in her curriculum and pedagogy. Data collected throughout the semester delivery of secondary school courses include a reflective personal journal on classroom activity; lessons and classroom documents; and feedback from students within the course. Four themes identified from the data that appeared to reduce mindless tendencies in my teaching practice were: i) having an intentionally evolving curriculum and pedagogy, ii) the inclusion of place-based learning opportunities, (iii) the inclusion of inquiry based learning opportunities, and iv) the importance of external validation. This research indicates that engaging with non-meditative mindfulness has an impact on both an educator’s thinking about his or her pedagogy and also on his or her practice. Employing non-meditative mindfulness may appeal to educators because it offers the opportunity for individuals to experience empowering, transformative ways of thinking without demanding that individuals commit significant amounts of time to modifying their practice.

description: The three-dimensional XY model is studied at finite chemical potential using complex Langevin dynamics. An adaptive stepsize algorithm is implemented to cure the problem of runaway solutions that appears when using a constant stepsize. The validity of complex Langevin dynamics is tested against calculations using imaginary chemical potential and the world line formalism. While complex Langevin dynamics is found to work correctly at larger beta, it fails for smaller beta, in the region of the phase diagram corresponding to the disordered phase. Diagnostic tests are developed to identify behaviour symptomatic of incorrect convergence. These indicate that the failure does not depend on the severeness of the sign problem, but has a different origin.

description: We consider an N=4 supersymmetric gauge theory on a curved space. We try to generalize Pestun's localization calculation on the four-sphere to a more general class of curved spaces. We calculated the Q-exact term to localize the path-integral, and when it becomes positive definite, we obtain a configuration where the path-integral localizes. We also evaluate the super Yang-Mills action in this configuration.

description: Recent experiments shown that graphene epitaxially grown on Silicon Carbide (SiC) can exhibit a energy gap of 0.26 eV, making it a promising material for electronics. With an accurate model, we explore the design parameter space for a fully ballistic graphene-on-SiC Tunnel Field-Effect Transistors (TFETs), and assess the DC and high frequency figures of merit. The steep subthreshold behavior can enable I_{ON}/I_{OFF} ratios exceeding 10^4 even with a low supply voltage of 0.15 V, for devices with gatelength down to 30 nm. Intrinsic transistor delays smaller than 1 ps are obtained. These factors make the device an interesting candidate for low-power nanoelectronics beyond CMOS.
Temporal variation in the traits of individuals and the extrinsic environment that influence nest success in an island songbird

description: Nest success is a key factor affecting the dynamics and life–history evolution of avian populations. While multiple factors affect nest success, their relative influence remains unclear, partly due to the short time periods over which many studies take place relative to the scales of temporal variation in the environment, and the traits of birds that make up populations. I examined the effects of two intrinsic (female age, inbreeding coefficient), two abiotic (rainfall, temperature), and three biotic (breeding densities, cowbird parasitism rates, and brood parasitism) factors potentially affecting nest success (≥ 1 fledged young) in an insular song sparrow (Melospiza melodia) population over 39 years. I also compared the influence of these factors in three 13–year intervals representing the early, mid and late periods of the study to estimate temporal influence. Over 39 years, song sparrow nesting success first increased (1 – 3 years), and then decreased with female age (3+ years), and declined in relation to the degree of inbreeding in females, increased rainfall during the nest period, and by increased breeding densities. Nests that were parasitized by brown–headed cowbirds, or that experienced increased risk of cowbird predation, tended to fail more often. Parallel analyses of nest success in the early, mid and late periods of the study showed that only female age and breeding densities explained success in all periods, whereas the effects of inbreeding, cowbirds, and rainfall were episodic through time. This discrepancy was due to temporal variation in abiotic or biotic conditions that affected which factors were most influential of success. Many studies of nest success in passerine birds are limited in duration and the number of variables that can be considered due to limits on the amount or quality of data, preventing the comparison of many biotic and abiotic factors reported to affect success in the literature. I show that over 39 years, the intrinsic effects of inbreeding, abiotic effects of climate and biotic effects of brood parasites on nest success were each influential but varied through time, indicating that any ranking of their relative influence on demography will also vary temporally.

description: We report the measurement of absolute excitation frequencies of 87Rb to nS and nD Rydberg states. The Rydberg transition frequencies are obtained by observing electromagnetically induced transparency on a rubidium vapor cell. The accuracy of the measurement of each state is < 1 MHz, which is achieved by frequency stabilizing the two diode lasers employed for the spectroscopy to a frequency comb and a frequency comb calibrated wavelength meter, respectively. Based on the spectroscopic data we determine the quantum defects of 87Rb, and compare it with previous measurements on 85Rb. We determine the ionization frequency from the 5S1/2(F=1) ground state of 87Rb to 1010.0291646(3) THz, providing the binding energy of the ground state with an accuracy improved by two orders of magnitude.

description: The capacity of the Gaussian wiretap channel model is analyzed when there are multiple antennas at the sender, intended receiver and eavesdropper. The associated channel matrices are fixed and known to all the terminals. A computable characterization of the secrecy capacity is established as the saddle point solution to a minimax problem. The converse is based on a Sato-type argument used in other broadcast settings, and the coding theorem is based on Gaussian wiretap codebooks. At high signal-to-noise ratio (SNR), the secrecy capacity is shown to be attained by simultaneously diagonalizing the channel matrices via the generalized singular value decomposition, and independently coding across the resulting parallel channels. The associated capacity is expressed in terms of the corresponding generalized singular values. It is shown that a semi-blind "masked" multi-input multi-output (MIMO) transmission strategy that sends information along directions in which there is gain to the intended receiver, and synthetic noise along directions in which there is not, can be arbitrarily far from capacity in this regime. Necessary and sufficient conditions for the secrecy capacity to be zero are provided, which simplify in the limit of many antennas when the entries of the channel matrices are independent and identically distributed. The resulting scaling laws establish that to prevent secure communication, the eavesdropper needs 3 times as many antennas as the sender and intended receiver have jointly, and that the optimimum division of antennas between sender and intended receiver is in the ratio of 2:1.

description: Topological subsystem codes proposed recently by Bombin are quantum error correcting codes defined on a two-dimensional grid of qubits that permit reliable quantum information storage with a constant error threshold. These codes require only the measurement of two-qubit nearest-neighbor operators for error correction. In this paper we demonstrate that topological subsystem codes (TSCs) can be viewed as generalizations of Kitaev's honeycomb model to trivalent hypergraphs. This new connection provides a systematic way of constructing TSCs and analyzing their properties. We also derive a necessary and sufficient condition under which a syndrome measurement in a subsystem code can be reduced to measurements of the gauge group generators. Furthermore, we propose and implement some candidate decoding algorithms for one particular TSC assuming perfect error correction. Our Monte Carlo simulations indicate that this code, which we call the five-squares code, has a threshold against depolarizing noise of at least 2%.
