description: We derive an analytic connection between the screened self-consistent effective potential from density functional theory (DFT) and atomic effective pseudopotentials (AEPs). The motivation to derive AEPs is to address structures with thousands to hundred thousand atoms, as given in most nanostructures. The use of AEPs allows to bypass a self-consistent procedure and to address eigenstates around a certain region of the spectrum (e.g., around the band gap). The bulk AEP construction requires two simple DFT calculations of slightly deformed elongated cells. The ensuing AEPs are given on a fine reciprocal space grid, including the small reciprocal vector components, are free of parameters, and involve no fitting procedure. We further show how to connect the AEPs of different bulk materials, which is necessary to obtain accurate band offsets. We derive a total of 20 AEPs for III-V, II-VI and group IV semiconductors and demonstrate their accuracy and transferability by comparison to DFT calculations of strained bulk structures, quantum wells with varying thickness, and semiconductor alloys.

description: A key distinguishing feature of conversational recommender systems over traditional recommender systems is their ability to elicit user preferences using natural language. Currently, the predominant approach to preference elicitation is to ask questions directly about items or item attributes. Users searching for recommendations may not have deep knowledge of the available options in a given domain. As such, they might not be aware of key attributes or desirable values for them. However, in many settings, talking about the planned use of items does not present any difficulties, even for those that are new to a domain. In this paper, we propose a novel approach to preference elicitation by asking implicit questions based on item usage. As one of the main contributions of this work, we develop a multi-stage data annotation protocol using crowdsourcing, to create a high-quality labeled training dataset. Another main contribution is the development of four models for the question generation task: two template-based baseline models and two neural text-to-text models. The template-based models use heuristically extracted common patterns found in the training data, while the neural models use the training data to learn to generate questions automatically. Using common metrics from machine translation for automatic evaluation, we show that our approaches are effective in generating elicitation questions, even with limited training data. We further employ human evaluation for comparing the generated questions using both pointwise and pairwise evaluation designs. We find that the human evaluation results are consistent with the automatic ones, allowing us to draw conclusions about the quality of the generated questions with certainty. Finally, we provide a detailed analysis of cases where the models show their limitations.

description: We study the slippage of a gas along mobile rigid walls in the sphere-plane confined geometry and find that it varies considerably with pressure. The classical no-slip boundary condition valid at ambient pressure changes continuously to an almost perfect slip condition in a primary vacuum. Our study emphasizes the key role played by the mean free-path of the gas molecules on the interaction between a confined fluid and solid surfaces and further demonstrates that the macroscopic hydrodynamics approach can be used with confidence even in a primary vacuum environment where it is intuitively expected to fail.

description: In this work, the linear and gauge-invariant theory of cosmological perturbations in a class of anisotropic and shear-free spacetimes is developed. After constructing an explicit set of complete eigenfunctions in terms of which perturbations can be expanded, we identify the effective degrees of freedom during a generic slow-roll inflationary phase. These correspond to the anisotropic equivalent of the standard Mukhanov-Sasaki variables. The associated equations of motion present a remarkable resemblance to those found in perturbed Friedmann-Robertson-Walker spacetimes with curvature, apart from the spectrum of the Laplacian, which exhibits the characteristic frequencies of the underlying geometry. In particular, it is found that the perturbations cannot develop arbitrarily large super-Hubble modes.

description: Multiuser switched-diversity scheduling schemes were recently proposed in order to overcome the heavy feedback requirements of conventional opportunistic scheduling schemes by applying a threshold-based, distributed, and ordered scheduling mechanism. The main idea behind these schemes is that slight reduction in the prospected multiuser diversity gains is an acceptable trade-off for great savings in terms of required channel-state-information feedback messages. In this work, we characterize the achievable rate region of multiuser switched diversity systems and compare it with the rate region of full feedback multiuser diversity systems. We propose also a novel proportional fair multiuser switched-based scheduling scheme and we demonstrate that it can be optimized using a practical and distributed method to obtain the feedback thresholds. We finally demonstrate by numerical examples that switched-diversity scheduling schemes operate within 0.3 bits/sec/Hz from the ultimate network capacity of full feedback systems in Rayleigh fading conditions.

Year: 2004

description: Bibliography: p. 180-211
description: This study addresses the issue of consumer behaviour and foodways between two ethnic groups, the Indigenous and the Spaniards, during early Colonial Mexico and the Postclassic period. My research interest concentrates on how socio-economic differences influenced the consumer behaviour and foodways between these two ethnic groups. For my objective, I compared material culture excavated in trash middens associated with Spaniards in the city of Puebla and Indigenous groups in the city of Cholula. The research relies on form-function analysis of ceramics, acquisition of goods, analysis of animal bones, unpublished historical documents consulted in the archives of Puebla, ethnohistoric data and ethnographic information. This study offers different explanations for the archaeological trends revealed by the material analysis based on social status, income, wealth, and ethnicity, all predicated on the hypothesis that social as well as economic elements influenced consumer behaviour and foodways in the Spaniards of Puebla and Indians of Cholula.

description: A subroutine for very-high-precision numerical solution of a class of ordinary differential equations is provided. For given evaluation point and equation parameters the memory requirement scales linearly with precision $P$, and the number of algebraic operations scales roughly linearly with $P$ when $P$ becomes sufficiently large. We discuss results from extensive tests of the code, and how one for a given evaluation point and equation parameters may estimate precision loss and computing time in advance.

Women's transformation in nothingness: a feminist-existential-transpersonal interpretive account of women's transformative experience of existential crisis

Year: 2004

description: Bibliography: p. 429-451
description: 'What is women's experience in Nothingness as a transformational experience?' The study of this question, through conducting interviews of five women's accounts of their lived-experience in Nothingness, resulted in an interpretive analysis of women's transformative experience of existential crisis. This study included an initial analysis of the research question to reveal what may influence our understanding of women's transformational experience in Nothingness. Thus, areas of knowledge relating to Nothingness, women and transformation were explored, including Western existential philosophy and psychology, women's psychology, and transpersonal psychology. The research topic required a methodology that would help the researcher remain sensitive to a phenomenon that was not definitive, but transformative, in nature. Thus, a research approach embracing methodological pluralism was utilized by blending together feminist, existential, and transpersonal epistemologies to yield a feminist-phenomenological- integral hermeneutics framework for research. Using this framework, research interviews produced narratives of the lived-experience of Nothingness in the lives of ordinary women. By analyzing and interpreting the deep meanings embedded within the narratives, ten themes emerged in response to the research question. The themes were: 1) early developmental experiences of Nothingness as the devalued female self, 2) disconnecting from the deep self and embracing socio-cultural scripts, 3) existential crisis and the descent into Nothingness, 4) women's ways of coping with the pain of Nothingness, 5) experiences of awakening, 6) spiritual searching and revaluing of the feminine, 7) breaking through: experiencing the mystical fullness of Nothingness, 8) cutting ties: hanging alone, 9) the never-ending process, and 10) the difficulty of ineffability and the need for mentoring.

description: The macroscopic response of granular solids is determined by the microscopic fabric of force chains, which, in turn, is intimately linked to the history of the solid. To query the influence of gravity on powder flow-behavior, a granular material is subjected to compression by a piston in a closed container, on-ground and in microgravity. Results show that piston-probing densifies the packing, eventually leading to jamming of the material compressed by the piston, regardless of the gravitational environment. The onset of jamming is found to appear at lower packing fraction in microgravity ($φ^{\textrm{$μ$-g}}_J = 0.567 \pm 0.014$) than on-ground ($φ^{\text{gnd}}_J = 0.579 \pm 0.014 $). We interpret these findings as the manifestation of a granular fabric altered by the gravitational force field: in absence of a secondary load (due to gravitational acceleration) to stimulate reorganization in a different direction to the major compression stress, the particles' configuration becomes stable at lower density, as the particles have no external drive to promote reorganization into a denser packing. This is coupled with a change in interparticular force balance which takes place under low gravity, as cohesive interactions become predominant. We propose a combination of microscopic and continuum arguments to rationalize our results.

description: Trojan asteroids are minor planets that share the orbit of a planet about the Sun and librate around the L4 or L5 Lagrangian points of stability. They are important because they carry information on early Solar System formation, when collisions between bodies were more frequent. Discovery and study of terrestrial planet Trojans will help constrain models for the distribution of bodies and interactions in the inner Solar System. We present models that constrain optimal search areas, and strategies for survey telescopes to maximize the probability of detecting inner planet Trojans. We also consider implications for detection with respect to the Gaia satellite, and limitations of Gaia's observing geometry.

description: The low temperature relaxation of the magnetization in magnetic molecular solids such as Fe$_8$ is studied using Monte Carlo simulations. A set of rate equations is developed to understand the simulations, and the results are compared. The simulations show that the magnetization of an initially saturated samples deviates as a square-root in time at short times, as observed experimentally, and this law is derived from the rate equations analytically.

description: The relationship between Russia and the United States is one of the most important inter-state relationships in the post-Cold War era. The former Cold War superpowers have navigated a strategic relationship that has been characterized by both cooperation and conflict throughout the 1990' s and beyond. For their part, Westem scholars studying this relationship have tended to view Russian foreign policy toward the United States as reactionary; however, given the magnitude of Russia's political transformation, there are numerous domestic factors that inform any understanding of its foreign policy. This thesis contends that, under Yeltsin, a number of domestic influences on foreign policy, taken together, better explain Russian policy toward the United States in two key strategic areas: its opposition to NATO expansion and its management of the joint arms control regime with Washington. The thesis finds that among the most critical of these influences were weak foreign policy institutions, strong leadership, the absence of a domestic consensus on Russia's role in the new world order, especially one dominated by its former enemy, and Yeltsin's willingness and propensity to use the tools at his disposal to dominate the policy process where possible, to advance his agenda. In light of recent challenges to Russia-U.S. relations in the new millennium, an understanding of its Russian influences in its formative years is necessary and useful for students seeking a more comprehensive understanding of the strategic relationship into the future.

description: The present study examined patterns of teacher-child interactions on children's sociometric status. The effects of teacher awareness of interaction patterns on subsequent teacher behavior was also examined. Characteristics of students of differing levels of sociometric status were explored through the use of the Pyryt Mendaglio Self-Perception Survey (PMSPS) and the Social Skills Rating System (SSRS). Participants were 8 grade three students and 6 grade six/seven students and their respective teachers. Results revealed differential teacher-student interactions with students of differing sociometric status. Differences in patterns were noted between age groups. Some teacher behavior change following awareness feedback was evident. Varying self-perceptions and perceptions of social relationships were noted between children with different levels of sociometric status.

description: We construct N=1 supersymmetrisations of some recently-proposed theories of critical gravity, conformal gravity, and extensions of critical gravity in four dimensions. The total action consists of the sum of three separately off-shell supersymmetric actions containing Einstein gravity, a cosmological term and the square of the Weyl tensor. For generic choices of the coefficients for these terms, the excitations of the resulting theory around an AdS_4 background describe massive spin-2 and massless spin-2 modes coming from the metric; massive spin-1 modes coming from a vector field in the theory; and massless and massive spin-3/2 modes (with two unequal masses) coming from the gravitino. These assemble into a massless and a massive N=1 spin-2 multiplet. In critical supergravity, the coefficients are tuned so that the spin-2 mode in the massive multiplet becomes massless. In the supersymmetrised extensions of critical gravity, the coefficients are chosen so that the massive modes lie in a "window" of lowest energies E_0 such that these ghostlike fields can be truncated by imposing appropriate boundary conditions at infinity, thus leaving just positive-norm massless supergravity modes.

description: In the present work we derive a Differential Emission Measure (DEM) dis- tribution from a region dominated by spicules. We use spectral data from the Solar Ultraviolet Measurements of Emitted Radiation (SUMER) spectrometer on-board the Solar Heliospheric Observatory (SoHO) covering the entire SUMER wavelength range taken off-limb in the Northern polar coronal hole to construct this DEM distribution using the CHIANTI atomic database. This distribution is then used to study the thermal properties of the emission contributing to the 171 Å channel in the Atmospheric Imaging Assembly (AIA) on-board the Solar Dynamics Observatory (SDO). From our off-limb DEM we found that the radiance in the AIA 171 Å channel is dominated by emission from the Fe ix 171.07 Å line and has sparingly little contribution from other lines. The product of the Fe ix 171.07 Å line contribution function with the off-limb DEM was found to have a maximum at logTmax (K) = 5.8 indicating that during spicule observations the emission in this line comes from plasma at transition region temperatures rather than coronal. For comparison, the same product with a quiet Sun and prominence DEM were found to have a maximum at logT max (K) = 5.9 and logTmax (K) = 5.7, respectively. We point out that the interpretation of data obtained from the AIA 171 Å filter should be done with foreknowledge of the thermal nature of the observed phenomenon. For example, with an off-limb DEM we find that only 3.6% of the plasma is above a million degrees, whereas using a quiet Sun DEM, this contribution rises to 15%.

description: The swampland conjecture known as Festina Lente (FL) imposes a lower bound on the mass of all charged particles in a quasi-de Sitter space. In this paper, we propose the aFL (axionic Festina Lente) bound, an extension of FL to axion-like particles arising from type II string theory. We find that the product of the instanton action and the axion decay constant is bounded from below by the vacuum energy. This is achieved indirectly, using dimensional reduction on Calabi-Yau threefolds, and translating the FL result for dipoles into a purely geometric bound. We discuss axionic black holes evolution, and aFL constraints on Euclidean wormholes, showing that the gravitational arguments leading to the FL bound for U$(1)$ charged particles cannot be directly applied to axions. Moreover, we discuss phenomenological implications of the aFL bound, including constraints on string inflation models and the axion-photon coupling via kinetic mixing.

description: Vector spin chirality is one of the fundamental characteristics of complex magnets. For a one-dimensional spin-spiral state it can be interpreted as the handedness, or rotational sense of the spiral. Here, using spin-polarized scanning tunneling microscopy, we demonstrate the occurrence of an atomic-scale spin-spiral in finite individual bi-atomic Fe chains on the (5x1)-Ir(001) surface. We show that the broken inversion symmetry at the surface promotes one direction of the vector spin chirality, leading to a unique rotational sense of the spiral in all chains. Correspondingly, changes in the spin direction of one chain end can be probed tens of nanometers away, suggesting a new way of transmitting information about the state of magnetic objects on the nanoscale.

description: Raman excitation and emission spectra for the radial breathing mode (RBM) are reported, together with a preliminary analysis. From the position of the peaks on the two-dimensional plot of excitation resonance energy against Raman shift, the chiral indices (m, n) for each peak are identified. Peaks shift from their positions in air when different pressure media are added - water, hexane, sulphuric acid - and when the nanotubes are unbundled in water with surfactant and sonication. The shift is about 2 - 3 cm-1 in RBM frequency, but unexpectedly large in resonance energy, being spread over up to 100meV for a given peak. This contrasts with the effect of pressure. The shift of the peaks of semiconducting nanotubes in water under pressure is orthogonal to the shift from air to water. This permits the separation of the effects of the pressure medium and the pressure, and will enable the true pressure coefficients of the RBM and the other Raman peaks for each (m, n) to be established unambiguously.

description: This paper studies the coupling of internally guided learning and social interaction, and more specifically the improvement owing to demonstrations of the learning by intrinsic motivation. We present Socially Guided Intrinsic Motivation by Demonstration (SGIM-D), an algorithm for learning in continuous, unbounded and non-preset environments. After introducing social learning and intrinsic motivation, we describe the design of our algorithm, before showing through a fishing experiment that SGIM-D efficiently combines the advantages of social learning and intrinsic motivation to gain a wide repertoire while being specialised in specific subspaces.

description: We use a simple, collision-based, discrete, random abrasion model to compute the profiles for the stoss faces in a bedrock abrasion process. The model is the discrete equivalent of the generalized version of a classical, collision based model of abrasion. Three control parameters (which describe the average size of the colliding objects, the expected direction of the impacts and the average volume removed from the body due to one collision) are sufficient for realistic predictions. Our computations show the robust emergence of steady state shapes, both the geometry and the time evolution of which shows good quantitative agreement with laboratory experiments.

description: Most galaxies host central supermassive black holes. As two galaxies merge, the black holes also merge. The final single black hole may suffer a kick due to asymmetric gravitational radiation and may not be at the centre of the galaxy; off-centre black holes may also be produced by other means such as sustained acceleration due to asymmetric jet power. We model the main galaxy as a singular isothermal sphere and the black hole as an off-centre point lens, and study the critical curves and caustics using complex notation. We identify the critical parameters that govern the transitions in the topology of critical curves, caustics and pseudo-caustics, and find the number of images can be two, three, four and five. We show examples of image configurations, including cases where three highly de-magnified images are found close to the centre. The perturbation on the image magnification due to the black hole scales linearly with its mass in the off-centre case, and quadratically when the black hole is at the centre. Such images are difficult to observe unless high-contrast and high-resolution imaging facilities (e.g., the Square Kilometer Array in the radio) become available.

The experiences of gay men in counselling

Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 145-158
description: The purpose of this study was to achieve a deeper understanding of what it is like for gay men to see a counsellor. Eight participants volunteered for the investigation. All had previous or concurrent counselling experience and used a self-referent identity label of "gay male." Participants ranged in age from 21 to over 50 at the time of data collection and all were able to provide a description of their experience in English. Data were gathered using an open-ended interview protocol and were analyzed using an integration of procedures for phenomenological data reduction outlined by Colaizzi (1978), Creswell (1998), Giorgi (1985), Moustakas (1994), Osborne (1990), and Patton (2002). Three categories (Antecedents, Moderating Variables, and Outcomes) and thirteen main themes emerged. Findings suggest that there are common elements among the needs of gay male clients that, if attended to, can improve the effectiveness with which service is provided to gay men.

description: This paper considers the cooperation between a cognitive system and a primary system where multiple cognitive base stations (CBSs) relay the primary user's (PU) signals in exchange for more opportunity to transmit their own signals. The CBSs use amplify-and-forward (AF) relaying and coordinated beamforming to relay the primary signals and transmit their own signals. The objective is to minimize the overall transmit power of the CBSs given the rate requirements of the PU and the cognitive users (CUs). We show that the relaying matrices have unit rank and perform two functions: Matched filter receive beamforming and transmit beamforming. We then develop two efficient algorithms to find the optimal solution. The first one has linear convergence rate and is suitable for distributed implementation, while the second one enjoys superlinear convergence but requires centralized processing. Further, we derive the beamforming vectors for the linear conventional zero-forcing (CZF) and prior zero-forcing (PZF) schemes, which provide much simpler solutions. Simulation results demonstrate the improvement in terms of outage performance due to the cooperation between the primary and cognitive systems.

Assessing performances of ecotechnologies for the treatment of feedlot run-off
Creators: name: Rowell, Jennifer Anne
Publisher: name: University of Calgary

description: Bibliography: p. 106-111
description: Run-off from livestock holding pens has the potential to degrade surface water quality with suspended solids, nutrients, oxygen demand and coliforms. Expansion of the Alberta livestock industry may exacerbate this problem unless steps are taken to improve water quality through prudent management practices, including run-off control and treatment. Ecotechnologies offer an alternative means for treating feedlot run-off Two treatment cells; a constructed wetland and a floodable meadow, were established at Little Red Feeders, Innisfail, Alberta. A series of experiments were conducted to evaluate treatment cell efficacy in agricultural contaminant removal. Analysis revealed that ecotechnology cell performance was highly variable in treating lagoon effluent derived from the run-off of a 4000-head beef cattle feedlot. At the very least, treatment cells of this size and design can aid in the attenuation of concentrated run­off from medium-sized Central Albertan feedlots during and immediately following storm events.
