Planning for the planning school: making the case for enhanced applied learning opportunities at the University of British Columbia’s School of Community and Regional Planning
Creators: name: Nicol, Jerome Sowle
Publisher: name: University of British Columbia
Year: 2009

description: The nature and role of higher education is changing. The relationship between the University, the student, and greater society is shifting. Internal (e.g., concerns about accessibility and inclusion) and external (e.g., funding and market demands) forces are converging in a way that demands a reconceptulization of higher education and the learning process. This thesis tries to identify and integrate varying facets that contribute to the changing landscape of university education, specifically focusing on the increased interest in applied learning opportunities at the post-secondary level, and the ways in which different professional and academic programs are incorporating such opportunities into their programs. These findings are interpreted in the context of graduate planning education at the University of British Columbia's School of Community and Regional Planning (SCARP). This qualitative study is grounded in an analytical reflection informed by my own experiences as a graduate planning student, by a review of academic, professional, government, and public press literature, and by interviews with various academics, administrators, and practitioners. The thesis presents an overview of literature from the field of planning education, and an introduction to the literature of higher education. This is followed by an examination of graduate planning schools in Canada and analogous professional/academic programs in British Columbia, which provide ample evidence and support for the emerging practice of incorporating indifferent types of applied learning opportunities (e.g., co-op program, internship, and practicum). A summary of trends, models of innovation, best practice ideals, and recommendations for graduate planning education at SCARP conclude the thesis. Most importantly, the recommendation is made for the school to continue and improve its trial internship program as well as persist in exploring ways of providing applied learning opportunities to students. Programs in higher education must continue to link theory and practice in ways that best serve students in today's changing society.

description: We investigate the effects of bosonic trilinear interactions in preheating after chaotic inflation. A trilinear interaction term allows for the complete decay of the massive inflaton particles, which is necessary for the transition to radiation domination. We found that typically the trilinear term is subdominant during early stages of preheating, but it actually amplifies parametric resonance driven by the four-legs interaction. In cases where the trilinear term does dominate during preheating, the process occurs through periodic tachyonic amplifications with resonance effects, which is so effective that preheating completes within a few inflaton oscillations. We develop an analytic theory of this process, which we call tachyonic resonance. We also study numerically the influence of trilinear interactions on the dynamics after preheating. The trilinear term eventually comes to dominate after preheating, leading to faster rescattering and thermalization than could occur without it. Finally, we investigate the role of non-renormalizable interaction terms during preheating. We find that if they are present they generally dominate (while still in a controllable regime) in chaotic inflation models. Preheating due to these terms proceeds through a modified form of tachyonic resonance.

description: To enable automated software testing, the ability to automatically navigate to a state of interest and to explore all, or at least sufficient number of, instances of such a state is fundamental. When testing a computer game the problem has an extra dimension, namely the virtual world where the game is played on. This world often plays a dominant role in constraining which logical states are reachable, and how to reach them. So, any automated testing algorithm for computer games will inevitably need a layer that deals with navigation on a virtual world. Unlike e.g. navigating through the GUI of a typical web-based application, navigating over a virtual world is much more challenging. This paper discusses how concepts from geometry and graph-based path finding can be applied in the context of game testing to solve the problem of automated navigation and exploration. As a proof of concept, the paper also briefly discusses the implementation of the proposed approach.

description: Oblivious transfer between two untrusting parties is an important primitive in cryptography. There are different variants of oblivious transfer. In Rabin oblivious transfer, the sender Alice holds a bit, and the receiver Bob either obtains the bit, or obtains no information with probability $p_?$. Alice should not know whether or not Bob obtained the bit. We examine a quantum Rabin oblivious transfer (OT) protocol that uses two pure states. Investigating different cheating scenarios for the sender and for the receiver, we determine optimal cheating probabilities in each case. Comparing the quantum Rabin oblivious transfer protocol to classical Rabin oblivious transfer protocols, we show that the quantum protocol outperforms classical protocols, which do not use a third party, for some values of $p_?$. We find that quantum Rabin OT protocols that use mixed states can outperform quantum Rabin OT protocols that use pure states for some values of $p_?$.

The Silken Cord: Contemporaneous 20th Century Prime Ministerial Biography in Australia & Its Meaning
Creators: name: Wallace, Christine
Publisher: name: Canberra, ACT : The Australian National University
Year: 2015

description: Political biography as political intervention is explored in this thesis: biography as action rather than as passive publication. This idea is investigated through contemporaneous political biography in twentieth century Australia — specifically, biographies written in the lead up to, or during, the active political careers of Australia's prime ministers from Barton to Howard. Australia had 25 prime ministers in this first century of Federation, but only 17 contemporaneous biographies of them were written and published. Three-quarters of these were written in the post-war period, and half were written in the 20th century's final two decades. Most were written by journalists. Given that perceptions of politicians influence their electability, and that biography can influence perceptions, this is a highly prospective area for testing the idea of biography as action — in this case, as political intervention. Here the metaphor of biography as a silken cord composed of several strands — historical, philosophical, psychological and political — can be seen to operate with specific application. The silken cord of biography slips on easily because of its familiar form; it is capable of dragging a politician's reputation up or down and may even be designed to hang them. While the biographer makes the cord, someone else may be holding onto it or subsequently seize it for their own ends. Of the 17 contemporaneous biographies examined here, the majority were found to promote or burnish the subject's standing - the silken cord lifting the subject up. One biography unequivocally sought to diminish the subject's standing - the silken cord dragging them down. This thesis takes perceptions of biography from a simplistic 'authorised/unauthorised' binary to a more nuanced exposition of its character and dynamics.

description: Ferrimagnet (FiM), (FeCo)1-xGdx, attracts research attention due to its ultrafast magnetic dynamics and finite net magnetization. Incorporating FiM into the magnetic tunnel junction will be beneficial to further improve the writing speed of magnetic random access memory (MRAM). It is commonly assumed that the FeCo and Gd atoms are switched together due to the strong exchange coupling, which remains valid even if one performs the two-sublattice macrospin simulation. Interestingly, using the atomistic model developed by our group, it is clearly seen that different atoms are not switched together. In addition, our study reveals that the nature of switching is spatially nonuniform even in the small sample with the dimension of 20 nm-20 nm. Furthermore, the characteristics of nonuniformity are completely different for samples with different Gd composition (x). When x is close to the magnetization compensation point, successful switching cannot be obtained, but is accompanied by the stable oscillation. The atom type that dominates the oscillation is different from that predicted by the two-sublattice macrospin model. In addition, the size of singular region is a non-monotonic function of current density. All these results can only be understood by considering the spatial nonuniform magnetization dynamics.

description: Spacetime variations of physical constants can be associated with the existence of Higgs-like scalar field(s) that couple non-universally to the baryonic matter. Recent results of astronomical spectral measurements of the fractional changes in the electron-to-proton mass ratio, mu = m_e/m_p, at low (z ~ 0) and high (z ~ 6.5) redshifts are discussed. It is shown that the distribution of the most accurate estimates of Delta mu/mu = (mu_obs - mu_lab)/mu_lab ranging between z = 0 and z ~ 1100 can be approximated by a power low Delta mu/mu = k_mu (1+z)^p, with k_mu = (1.7 +/- 0.3)x10^-8 and p = 1.99 +/- 0.03, implying a dynamical nature of the scalar field(s).

A current-voltage model for double Schottky barrier devices

Year: 2020
Subjects: subject: Applied Physics (physics.app-ph)

description: Schottky barriers are often formed at the semiconductor/metal contacts and affect the electrical behaviour of semiconductor devices. In particular, Schottky barriers have been playing a major role in the investigation of the electrical properties of mono and two-dimensional nanostructured materials, although their impact on the current-voltage characteristics has been frequently neglected or misunderstood. In this work, we propose a single equation to describe the current-voltage characteristics of two-terminal semiconductor devices with Schottky contacts. We apply the equation to numerically simulate the electrical behaviour for both ideal and non-ideal Schottky barriers. The proposed model can be used to directly estimate the Schottky barrier height and the ideality factor. We apply it to perfectly reproduce the experimental current-voltage characteristics of ultrathin molybdenum disulphide or tungsten diselenide nanosheets and tungsten disulphide nanotubes. The model constitutes a useful tool for the analysis and the extraction of relevant transport parameters in any two-terminal device with Schottky contacts.

description: The dynamics of a triangular magnetocapillary swimmer is studied using the lattice Boltzmann method. Performing extensive numerical simulations taking into account the coupled dynamics of the fluid-fluid interface and of magnetic particles floating on it and driven by external magnetic fields we identify several regimes of the swimmer motion. In the regime of high frequencies the swimmer's maximum velocity is centered around the particle's inverse coasting time. Modifying the ratio of surface tension and magnetic forces allows to study the swimmer propagation in the regime of significantly lower frequencies mainly defined by the strength of the magnetocapillary potential. Finally, introducing a constant magnetic contribution in each of the particles in addition to their magnetic moment induced by external fields leads to another regime characterised by strong in-plane swimmer reorientations that resemble experimental observations.

description: We investigate the one-dimensional ferromagnetic Kondo lattice in the hole-rich region. Of interest to us is the intermediate situation where the ferromagnetic Kondo coupling (Hund's coupling) is comparable to the electron bandwidth. The forced alignment favors triplet states whereas singlet states enter in a quite low-density regime. The direct antiferromagnetic exchange between the core spins is assumed to still prevail over the double exchange. We discuss a solvable limit showing that short-range antiferromagnetism in the spin array will affect the coherent propagation of triplets, i.e., turns a light triplet onto a heavy singlet, resulting in a heavy electron ground state.

description: Synchronization manifests itself in oscillators adjusting their frequencies and phases with respect to an external signal or another oscillator. In the quantum case, new features appear such as destructive interferences that can result in the suppression of phase locking. A three-level (spin-1) oscillator with equal gain and damping rates and subject to an external drive does not exhibit any 1:1 phase locking but 2:1 phase locking, i.e., its phase distribution features two maxima. This bistable locking at two opposite phases is a signature of the quantum interference synchronization blockade. An analogous behavior was found for two identical coupled spin-1 oscillators. In this work, we consider two coupled spin-1 oscillators and a drive applied to the first spin. This leads to two interference blockades between the drive and the first spin as well as between both spins. Although both interference blockades persist for strong drive and coupling strengths, remarkably, the undriven spin does show a 1:1 phase locking to the external drive. The magnitude of the locking is proportional to the drive strength if the drive strength is small. In other words, the undriven oscillator synchronizes to the external drive through both interference blockades while the blockades persist. For a chain of three coupled spin-1 oscillators, we find synchronization between the first and third spins mediated via the blockaded, second spin.

description: Using the covariant spectator theory (CST), we present two one boson exchange kernels that have been successfully adjusted to fit the 2007 world np data (containing 3788 data) below 350 MeV. One model (which we designate WJC-1) has 27 parameters and fits with a chi2/N = 1.06. The other model (designated WJC-2) has only 15 parameters and fits with a chi2/N = 1.12. Both of these models also reproduce the experimental triton binding energy without introducing additional irreducible three-nucleon forces. One result of this work is a new phase shift analysis, updated for all data until 2006, which is useful even if one does not work within the CST. In carrying out these fits we have reviewed the entire data base, adding new data not previously used in other high precision fits and restoring some data omitted in previous fits. A full discussion and evaluation of the 2007 data base is presented.

description: An impact of the finite size effects on the vacuum free energy density of full QCD with $N_{\rm f}$ massless flavors in the presence of homogeneous (anti-)self-dual Abelian background gluon field is studied. The zero temperature free energy density of the four-dimensional spherical domain is computed as a function of the background field strength $B$ and domain radius $R$. Calculation is performed in the one-loop approximation improved by accounting for mixing of the quark and gluon quasi-zero modes with normal modes, with the use of the $ζ$-function regularization. It is indicated that, under plausible assumption on the character of the mixing, the quantum correction to the free energy density has a minimum as a function of $B$ and $R$. Within the mean field approach to QCD vacuum based on domain wall network representation of the mean field, an existence of the minimum may prevent infinite growth of individual domain, thus protecting the vacuum from the long-range ordering, and, hence, serving as the origin of disorder in the statistical ensemble of domain wall networks, driven by the minimization of the overall free energy of the dominant gauge field configurations.

C {\bf 74}, 031301(R) (2006) using synchrotron radiation near the Au $K$-edge. We predict the behavior of $σ_{N^*}$ as a function of the incident photon energy for nuclei $^{193}$Ir and $^{189}$Os. We reveal that the $^{189}$Os excitation begins when the energy of incident photons is below the $K$-shell ionization threshold in Os.

description: Diffusive random walks feature the surprising property that the average length of all possible random trajectories that enter and exit a finite domain is determined solely by the domain boundary. Changes in the diffusion constant or the mean-free path, that characterize the diffusion process, leave the mean path length unchanged. Here we demonstrate experimentally that this result can be transferred to the scattering of waves, even when wave interference leads to marked deviations from a diffusion process. Using a versatile microwave setup, we establish the mean path length invariance for the crossover to Anderson localization and for the case of a band gap in a photonic crystal. We obtain these results on the mean path length solely based on a transmission matrix measurement through a novel procedure that turns out to be more robust to absorption and incomplete measurement in the localized regime as compared to an assessment based on the full scattering matrix.

description: We discuss a polymer model for the 3D organization of human chromosomes. A chromosome is represented by a string of beads, with each bead being "colored" according to 1D bioinformatic data (e.g., chromatin state, histone modification, GC content). Individual spheres (representing bi- and multi-valent transcription factors) can bind reversibly and selectively to beads with the appropriate color. During molecular dynamics simulations, the factors bind, and the string spontaneously folds into loops, rosettes, and topologically-associating domains (TADs). This organization occurs in the absence of any specified interactions between distant DNA segments, or between transcription factors. A comparison with Hi-C data shows that simulations predict the location of most boundaries between TADs correctly. The model is "fitting-free" in the sense that it does not use Hi-C data as an input; consequently, one of its strengths is that it can -- in principle -- be used to predict the 3D organization of any region of interest, or whole chromosome, in a given organism, or cell line, in the absence of existing Hi-C data. We discuss how this simple model might be refined to include more transcription factors and binding sites, and to correctly predict contacts between convergent CTCF binding sites.

description: The local structure of CeTe3 in the incommensurate charge density wave (IC-CDW) state has been obtained using atomic pair distribution function (PDF) analysis of x-ray diffraction data. Local atomic distortions in the Te-nets due to the CDW are larger than observed crystallographically, resulting in distinct short and long Te-Te bonds. Observation of different distortion amplitudes in the local and average structures are explained by the discommensurated nature of the CDW since the PDF is sensitive to the local displacements within the commensurate regions whereas the crystallographic result averages over many discommensurated domains. The result is supported by STM data. This is the first quantitative local structural study within the commensurate domains in an IC-CDW system.

description: Most astrophysical accretion disks are likely to be warped. In X-ray binaries the spin evolution of an accreting neutron star is critically dependent on the interaction between the neutron star magnetic field and the accretion disk. There have been extensive investigations on the accretion torque exerted by a coplanar disk that is magnetically threaded by the magnetic field lines from the neutron stars, but relevant works on warped/tilted accretion disks are still lacking. In this paper we develop a simplified two-component model, in which the disk is comprised of an inner coplanar part and an outer, tilted part. Based on standard assumption on the formation and evolution of the toroidal magnetic field component, we derive the dimensionless torque and show that a warped/titled disk is more likely to spin up the neutron star compared with a coplanar disk.We also discuss the possible influence of various initial parameters on the torque.

description: It has been proven that in standard Einstein gravity, exotic matter is required to stabilize traversable wormholes. Quantum field theory permits these violations due to the quantum coherent effects found in any quantum field. Even reasonable classical scalar fields violate the energy conditions. In the case of the Casimir effect and squeezed vacuum states, these violations have been experimentally proven. It is advantageous to investigate methods to minimize the use of exotic matter. One such area of interest is extended theories of Einstein gravity. It has been claimed that in some extended theories, stable traversable wormholes solutions can be found without the use of exotic matter. There are many extended theories of gravity, and in this review paper, we first explore modified gravity theories and then explore some wormhole solutions in such theories, including Lovelock gravity and Einstein Dilaton Gauss Bonnet gravity. For completeness, we have also reviewed other wormholes such as Casimir wormholes, dark matter halo wormholes, thin-shell wormholes, and Nonlocal Gravity wormholes, where alternative techniques are used to either avoid or reduce the amount of exotic matter that is required.

Voices and roles of competing groups of elite women in Siam's political and social transitions, 1868-1942
Creators: name: Posrithong, Natanaree
Publisher: name: The Australian National University
Year: 2015

description: This dissertation studies the pivotal roles and voices of elite women of both aristocratic and commoner backgrounds in the significant period of Siam's political and social transitions from the late absolute monarchy to the early post-revolutionary period between 1868 and 1942. A key focus of this study is the competition between the two groups of aristocrats and commoner women. By analysing representations of women in Thai mainstream and official publications, this dissertation critiques the lack of emphasis on Siamese women's public roles and voices in dominant historiographical discourse. This study presents a counter-argument to these works by demonstrating elite women's agency in the four domains of: state public administration, education, print media, and politics. Siamese women entered the public sphere by taking administrative roles in the royal palace from the late nineteenth century during the absolutist reign of King Chulalongkorn. It was in this period that aristocratic women realised the importance of skills other than domestic training in arts and crafts, and they began initiatives in female public education from the end of the nineteenth century. As the result of women's improved access to education, a new class of commoner elite women emerged in the early twentieth century. These literate commoner women competed against aristocratic elite women in the print industry and in politics from the beginning of the post-absolutist period in the early 1930s. This dissertation highlights the competition between these two groups of women as a distinctive contribution to the field of Thai women's history. This study is based on analysis of personal memoirs from cremation volumes, archival records, and women's magazines. Through considering these source materials, this dissertation reveals the previously overlooked roles of women in Siam's transition from an absolute monarchy to a constitutional monarchy.

description: We investigated the interlayer coupling effect in homobilayer structures of MSi2X4 with M = Mo/W and X = N/P/As. Through the combination of first-principles calculations and analytical formulations, the equilibrium interlayer distance, layer energy difference and interlayer hopping strength are obtained for all six MSi2X4 materials, which are found to be insensitive to the type of M atom but differ significantly between X = N and X = P/As. In homobilayers with close to 0° twist angles, the interlayer charge redistribution introduces a stacking-dependent interlayer electrostatic potential with a magnitude reaching 0.1 eV in MSi2N4, suggesting that it can be an excellent candidate for studying the sliding ferroelectricity. The interlayer hopping strengths are found to be as large as several tens meV at valence band maxima positions K and Γ, and ~ 1 meV at the conduction band edge K. The resultant layer-hybridizations vary in a large range under different stacking registries, which can be used to simulate honeycomb lattice models with both trivial and non-trivial band topologies.

Labrum produced as triangular elevation, about as long as wide, with surface divided into facets by cuticular ridges and bearing at least four pores: two in posterior midline and additional pair of pores rather posteriorly along left and right labral margins. Caudal end broadly acute, terminating in 10 µm long dorso-caudal spine with one or two annulate ridges, this spine being flanked ventro-laterally by pair of tiny, pointed furcal spines, these being situated slightly ventral to, and forward from, base of dorso-caudal spine.
CYPRID VIEWED THROUGH CUTICLE OF LSN. Body pigmentation varying among examined specimens: one dark brown overall except in marginal areas, and telson with distinct, reddish-brown pigmentation; in another, only telson brown. Telson about as long as wide and half as long as thorax.
Identification and variation
Easy recognizable by its narrow-ovate form, dorso-ventrally flattened appearance and tiny furcal spines. Some variation was seen in the size of the furcal and dorso-caudal spines and in the pigmentation of the cyprid inside the LSN (see above).
Distribution
Japan (Sesoko Island, Okinawa).

description: Recently proposed consistency-based Semi-Supervised Learning (SSL) methods such as the $Π$-model, temporal ensembling, the mean teacher, or the virtual adversarial training, have advanced the state of the art in several SSL tasks. These methods can typically reach performances that are comparable to their fully supervised counterparts while using only a fraction of labelled examples. Despite these methodological advances, the understanding of these methods is still relatively limited. In this text, we analyse (variations of) the $Π$-model in settings where analytically tractable results can be obtained. We establish links with Manifold Tangent Classifiers and demonstrate that the quality of the perturbations is key to obtaining reasonable SSL performances. Importantly, we propose a simple extension of the Hidden Manifold Model that naturally incorporates data-augmentation schemes and offers a framework for understanding and experimenting with SSL methods.
Living leprosy in Vietnam: care, affliction and agency in the shadows of a cure

description: Today in Vietnam leprosy is deemed to be on the threshold of elimination as a result of a concerted public health program and the decades-long application of an effective multidrug cure. However, many thousands of people continue to live with the painful, debilitating and degrading effects of this chronic disease. Although integrated community care is the prescribed model for treatment, most leprosy sufferers still live in exclusive communities for leprosy patients. Despite official efforts to cure, normalise and destigmatise the disease, people with severe leprosy symptoms are readily visible in public spaces where they excite abhorrence and compassion among the alms-giving public. Presenting the results of ethnographic fieldwork in Quy Hoa leprosy village in South-Central Vietnam, one of the largest communities for leprosy sufferers in Vietnam, this thesis seeks to examine the lived realities of people afflicted with leprosy and account for the unexpected resilience of this disease. Through ethnographic exploration of the life experiences of leprosy sufferers, the thesis investigates the tenacity of leprosy as a lived reality and multidimensional affliction. The study examines the ethics and modalities of care for leprosy-afflicted people and their embodied memories as subjects of care and neglect. Exploring the reactions provoked by a disease diagnosis, the thesis tracks into the cultural construction of an affliction which, until only a generation ago, condemned its victims to social degradation and exile. Examining the therapeutic benefits to leprosy sufferers of living in segregated communities for people with the same disease, it documents the harmful persistence of leprosy stigma in the face of public health approaches designed to normalise the disease. It describes the chronic complications, disabilities, physical disfigurement and shame with which many leprosy sufferers live in the shadows of a dominant biomedical construction of leprosy as an easily curable disease. This research shows that the resilience of leprosy derives from its ingrained power as a cultural symbol and embodied identity. Public health discourses that declare leprosy to be on the verge of eradication exist in tension with the lived experiences of leprosy sufferers and the survival of popular images of the leper as a figure of misery and compassion. The thesis finds that while leprosy is debilitating, it also can be productive. The symbolic power of leprosy is instrumentalised as a form of illness capital by leprosy sufferers who display and enact the disease to secure charitable assistance in the context of declining state welfare support. The analysis thus sheds light on the multiple dimensions of care, embodied affliction and agency that contribute to the tenacious survival of this disease.
Multi-waveband quasi-periodic oscillations in the light curves of blazar CTA 102 during its 2016-2017 optical outburst

description: Quasi-periodic fluctuations in the light curves of blazars can provide insight into the underlying emission process. This type of flux modulation hints at periodic physical processes that result in emission. CTA 102, a flat spectrum radio quasar at $z=1.032$, has displayed significant activity since 2016. The multi-waveband light curve of CTA 102 shows signs of quasi-periodic oscillations during the 2016-2017 flare. Our goal is to quantify the presence of any periodicity in the emitted flux during the mentioned period and to explore the causes that can give rise to it. Techniques such as the Lomb-Scargle periodogram and weighted wavelet z-transform were employed to observe the power emitted at different frequencies. To quantify the significance of the dominant period, Monte-Carlo techniques were employed considering an underlying smooth bending power-law model for the power spectrum. In addition, the light curve was modeled using an autoregressive process to analytically obtain the significance of the dominant period. Lastly, the light curve was modeled using a generalized autoregressive integrated moving average process to check whether introducing a periodic component results in a statistically preferable model. Significant, simultaneous quasi-periodic oscillations (QPOs) were observed in the $γ$-ray and optical fluxes of blazar CTA 102 during its 2016-2017 flare. The periodic flux modulation had a dominant period of $\sim$ 7.6 days and lasted for $\sim$ 8 cycles (MJD 57710-57770). All of the methods used point toward significant ($>4σ$) quasi-periodic modulation in both $γ$-ray and optical fluxes. Several possible models were explored while probing the origin of the periodicity, and by extension, the 2016--2017 optical flare. The best explanation for the detected QPO appears to be a region of enhanced emission, moving helically inside the jet.

description: The $ν_e-^{56}$Fe cross section is evaluated in the projected quasiparticle random phase approximation (PQRPA). This model solves the puzzle observed in RPA for nuclei with mass around $^{12}$C, because it is the only RPA model that treats the Pauli principle correctly. The cross sections as a function of the incident neutrino energy are compared with recent theoretical calculations of similar models. The average cross section weighted with the flux spectrum yields a good agreement with the experimental data. The expected number of events in the detection of supernova neutrinos is calculated for the LVD detector leading to an upper limit for the electron neutrino energy of particular importance in this experiment
