The meaning of home care and caring for aging relatives at home : the Haitian Canadian primary caregivers’ perspectives
Creators: name: Racine, Louise
Publisher: name: University of British Columbia
Year: 2009

description: Providing nursing care in pluralist countries such as Canada remains a challenge for nurses. Little is known about the impact of 'race,' gender, and social class in mediating Haitian Canadian caregivers' ways of caring for aging relatives at home. This critical ethnography, informed by a postcolonial feminist theoretical approach, was directed at addressing two questions: What are the Haitian Canadian caregivers' ways of caring for an aging relative at home? and What are the contextual factors that might impinge on Haitian Canadian caregivers' access to public home care services? The study was carried out in Eastern Canada. A sample of convenience, composed of 16 Haitian Canadian primary caregivers, nineteen aging persons, and four home care nurses, was formed. Twelve out of sixteen participants were women - mostly daughters who were caring for aging mothers. Participant observation and open-ended interviews were used to collect data from primary caregivers. Fieldwork was carried out during two periods. The first part was from November 2000 to August 2001, during which, 21 interviews and 15 sessions o f participant observation at caregivers' home were conducted. The second part was from October 2001 to February 2002, during which, 3 validity interviews were conducted with some participants to map out the data analysis. A postcolonial feminist framework guided data collection and analysis. A thematic content analysis was conducted. Results indicated that ways of caring are enmeshed in a complex nexus of social relations where power, race, gender, social class come into play to permeate each level of the caring commitment. Caring is a process of reciprocal growth. Ways of caring are structured by Haitian values, gendering of caring activities, immigration, social 'Othering,' health care reform, and cultural misunderstanding of mainstream health practitioners. These factors explain why this community tends to underutilize public home care programs. The study points to designing culturally safe nursing interventions and revising current neocolonial home care policies. The findings underline the need to redirect nursing cultural research to address racial, gendered, and social discrimination that influence the economic accessibility to home care support programs for low-income immigrant families in Canada, creating social inequities in our health care system.

description: Using the basic ingredient of supersymmetry, we develop a simple alternative approach to perturbation theory in one-dimensional non-relativistic quantum mechanics. The formulae for the energy shifts and wave functions do not involve tedious calculations which appear in the available perturbation theories. The model applicable in the same form to both the ground state and excited bound states, unlike the recently introduced supersymmetric perturbation technique which, together with other approaches based on logarithmic perturbation theory, are involved within the more general framework of the present formalism.

description: We present several improvements to the Cauchy-characteristic evolution procedure that generates high-fidelity gravitational waveforms at $\mathcal{I}^+$ from numerical relativity simulations. Cauchy-characteristic evolution combines an interior solution of the Einstein field equations based on Cauchy slices with an exterior solution based on null slices that extend to $\mathcal{I}^+$. The foundation of our improved algorithm is a comprehensive method of handling the gauge transformations between the arbitrarily specified coordinates of the interior Cauchy evolution and the unique (up to BMS transformations) Bondi-Sachs coordinate system of the exterior characteristic evolution. We present a reformulated set of characteristic evolution equations better adapted to numerical implementation. In addition, we develop a method to ensure that the angular coordinates used in the volume during the characteristic evolution are asymptotically inertial. This provides a direct route to an expanded set of waveform outputs and is guaranteed to avoid pure-gauge logarithmic dependence that has caused trouble for previous spectral implementations of the characteristic evolution equations. We construct a set of Weyl scalars compatible with the Bondi-like coordinate systems used in characteristic evolution, and determine simple, easily implemented forms for the asymptotic Weyl scalars in our suggested set of coordinates.
Cosmological particle-based simulations of galaxy formation; numerical loss of angular momentum and disk heating

description: We discuss the role that numerical effects have in cosmological N-Body/SPH simulations of disk galaxy formation. We show that the resolution of current state-of-the-art calculations, about $10^5$ SPH and dark matter particles within the virial radius of a Milky Way-sized halo at $z=0$, is just enough to avoid artificial losses of angular momentum and dramatic numerical disk heating during the phase of disk assembly. Instead both effects will still be an issue at earlier epochs, when the progenitors of the final galaxies are resolved by significantly less than $10^5$ particles.This must be at least partially responsible for why simulations show a ubiquitous low angular momentum spheroid that is too massive compared to that of typical disk galaxies

description: O estudo apresenta um relato de experiência sobre a construção de registros e materiais do artesanato de barro da Comunidade Água Boa II, norte do estado de Minas Gerais, Brasil. A pesquisa contempla entrevistas com duas artesãs que mantêm o modo tradicional de trabalhar com o barro, preservando o fazer artesanal. No período de 1980 a 2000, o artesanato de barro foi a base econômica da referida comunidade, porém, atualmente esta prática se faz cada vez menos presente no cotidiano dos moradores. Desse modo, o presente estudo teve como objetivo investigar o processo de confecção de peças artesanais como jarros, panelas e filtros, além da compreensão da relevância cultural e econômica desta prática, abordando questões referentes à cultura do trabalho feminino. Durante a pesquisa, percebemos que o artesanato tradicional sofreu uma queda, tanto na confecção quanto na geração de renda, exigindo que as artesãs se reinventassem para continuar praticando sua arte.

description: The morphological and electronic properties of isolated and monolayer phases of carboxyl- and amine-functionalized carboranethiols on unreconstructed Au(111) were determined using density functional theory calculations by including van der Waals interactions. The groups are effective in the assembly of pristine adlayers on gold and also offer functionality when exposed at the SAM-environment interface. Anisotropy brought by both functional groups increases tilting of carboranethiols relative to the surface normal and absolute values of the dissociative chemisorption energies. Positional isomerization and the functional groups modify the molecular dipole moments which influnce the adsorption characteristics. Even though carboxylic acid and amine groups have different chemical properties, they have similar effects on the adsoprtion characteristics of carboranethiols. Dense packing favors intermolecular interactions which gives a stronger binding relative to isolated adsorption. The carboranethiols with the functional groups can be arranged in the same lateral direction or in a dimer conformation with molecues facing each other. Carboxyl and amine groups offer functionalization of cabranethiol SAMs and in conjuction with positional isomerization shift tunability ranges of the work function of gold to higher energies.

description: Matrix product states provide a natural entanglement basis to represent a quantum register and operate quantum gates on it. This scheme can be materialized to simulate a quantum adiabatic algorithm solving hard instances of a NP-Complete problem. Errors inherent to truncations of the exact action of interacting gates are controlled by the size of the matrices in the representation. The property of finding the right solution for an instance and the expected value of the energy are found to be remarkably robust against these errors. As a symbolic example, we simulate the algorithm solving a 100-qubit hard instance, that is, finding the correct product state out of ~ 10^30 possibilities. Accumulated statistics for up to 60 qubits point at a slow growth of the average minimum time to solve hard instances with highly-truncated simulations of adiabatic quantum evolution.

description: The analysis of technical efficiency (TE) on the small-scale fishery is relevant for several reasons. While this type of fishery is highly common in developing countries like Mexico, there are a very limited number of analyses assessing their efficiency. Indeed, there is no precise information on the contribution of the small-scale fisheries to livelihoods and economies in developing nations. Exploring this gap in the research would be relevant for the decision making policy. On the one hand, small-scale fisheries can generate significant profits and be more resilient to shocks and crises; two important elements to poverty alleviation and food security. But on the other hand, small-scale fisheries may overexploit stocks, harming the environment and generating low profits. Certainly, it is desirable the preservation of resources of common access like lakes or reservoirs, at the same time it is desirable an efficient use of the fishery. The question is what factors constrain the efficiency? Aiming for a contribution on the knowledge of the small-scale fisher’s performance; this research applies “directed acyclic graphs”, an innovative technique to explore the causal relationship on the variables to explain the TE. To assess the fisher’s TE, this research uses “stochastic frontier analysis”, a method commonly used to estimate the efficiency. This study explores the causal pattern among the production function variables to corroborate, by estimating the TE, the hypothesis that: fisher’s skills favor the fisher performance. Compared to previous research, the results show an improvement on the assessment of the variables that constrain the efficiency. Getting a more precise TE assessment is valuable information. It would help to define the strategies for the assistance of the fishing communities; in a search for a policy to remedy the production inefficiencies and increase the competitiveness in small-scale fisheries.
Enzymatic Control of Intermolecular Interactions for Selective Targeting Golgi Apparatus

Subjects: Chemical Sciences

description: Nanoarchitectonics, as a technology to arrange nano-sized structural units such as molecules in a desired configuration, requires nano-organization, which usually relies on intermolecular interactions, a phenomenon ubiquitous in biology but relatively less explored by chemists and materials scientists. During the past two decades, nanoarchitectures generated intracellularly, extracellularly, or intercellularly exhibit diverse range of functions and result in rapid development. This thesis focuses on using enzymatic reactions to control intermolecular interactions for generating artificial nanoarchitectures in a cellular environment, especially at the sites of subcellular organelles to trigger various cellular responses and control the cell fate. Each chapter of this thesis highlights the design and modification of the enzyme substrates for intracellular noncovalent synthesis of nanoarchitectures, as well as their potential bioapplications. Through the exploration of these applications, the work in the thesis aims to update the use of enzymatic reaction in regulating intermolecular interactions for targeting subcellular organelles and stimulate new developments in this simple and versatile approach for addressing societal needs.

Civic tradition & planning processes : a comparative study of two resource communities in Northern Ontario
Creators: name: Lewis, Jill
Publisher: name: University of British Columbia
Year: 2009

description: This thesis studies the interplay between civic tradition and planning processes through a comparative case study of two Northern Ontario resource towns, Atikokan and Elliot Lake. It assesses the degree of community-wide social capital in these two towns and examines the origin and nature of their civic traditions. It addresses these questions: once a community's civic tradition has been established, how does this tradition affect the execution of planning processes? Do planning processes have the power to affect civic tradition? It is hypothesized that the structure of planning processes employed during the communities' formative years unintentionally wove the communities' social fabrics. Historical documents and interviews with key informants indicate that technocrats from the provincial government and private consulting firms planned Elliot Lake prior to the arrival of its citizens, while Atikokan was developed in the absence of a master plan and with little guidance from the state. Subsequently, both communities lost their major industries, re-doubled their efforts, and built new economic bases. In preparation for economic renewal, Elliot Lake employed an open, participatory planning process, while Atikokan's redevelopment took place behind closed doors. It is concluded that the structure of formative planning processes is a symptom, rather than a cause, of social capital formation. It is the philosophies, attitudes, and values of resource towns' 'founding fathers' (often managers from the resource companies or government-appointed administrators) and pioneers, as well as the resource companies' corporate cultures, that serve as the primary breeding grounds of its social capital. Once formed, social capital manifests itself in a community's conscious civic culture. This culture then passes on from generation to generation. A community's response to consequential disruptions in the macro-environment determines the way in which a community's civic tradition evolves. Planning processes merely reflect and reinforce a community's civic tradition; they do not fundamentally change it. Therefore, planners ought to understand the civic culture of the communities in which they work and they ought to employ planning techniques that are appropriate to a community's social, cultural, and political dynamics.

description: We have fabricated a Cooper-pair transistor (CPT) with parameters such that for appropriate voltage biases, the sub-gap charge transport takes place via slow tunneling of quasiparticles that link two Josephson-coupled charge manifolds. In between the quasiparticle tunneling events, the CPT behaves essentially like a single Cooper-pair box (SCB). The effective capacitance of a SCB can be defined as the derivative of the induced charge with respect to gate voltage. This capacitance has two parts, the geometric capacitance, C_geom, and the quantum capacitance C_Q. The latter is due to the level anti-crossing caused by the Josephson coupling. It depends parametrically on the gate voltage and is dual to the Josephson inductance. Furthermore, it's magnitude may be substantially larger than C_geom. We have been able to detect C_Q in our CPT, by measuring the in-phase and quadrature rf-signal reflected from a resonant circuit in which the CPT is embedded. C_Q can be used as the basis of a charge qubit readout by placing a Cooper-pair box in such a resonant circuit.

description: Bacteria have the option of initiating adaptive transcription to deal with the stress or to form a defensive community of a biofilm in order to survive. Here, we identified how bacteria utilize a modular toolkit of signaling proteins with exchangeable domains to survive in adverse environments. Two serine/threonine phosphatases activate the general stress response in B. subtilis, but how sensor proteins transduce species-specific signals to initiate the response is not known. Here we report the regulatory mechanism by which these phosphatases are activated. Both phosphatases require the phosphatase domains to be in the correct dimeric conformation in order for there to be metal cofactor binding and activation. Importantly, we present evidence that related coiled-coil linkers and phosphatase dimers transduce signals from diverse sensor domains to control the General Stress Response and other signaling across bacterial phyla. Additionally, we have shown that two unrelated members of this signaling toolkit come together to regulate biofilm formation in S. aureus. These biofilms assemble during infections or under laboratory conditions by growth on medium containing glucose, but the intracellular signal for biofilm formation and its downstream targets were unknown. Previous work identified genes needed for the release of extracellular DNA, including the gene for the cyclic-di-AMP phosphodiesterase GdpP, Biofilm formation is triggered by a drop in second messenger nucleotide cyclic-di-AMP. We additionally show that the downstream consequence of the drop in cyclic-di-AMP is inhibition of the “accessory gene regulator” operon agr, which is known to suppress biofilm formation through phosphorylation of the transcriptional regulator AgrA by the histidine kinase AgrC. Surprisingly we find that GdpP directly binds to autophosphorylated AgrC, which inhibits phosphotransfer to AgrA, allowing for biofilm formation. These results additionally resolve the mystery of how shared sensory domains control serine/threonine phosphatases, diguanylate cyclases and histidine kinases, revealing a common coiled-coil linker transduction mechanism.

description: This paper determines the dynamic interaction between prices of corn, soybean, grain sorghum (milo), wheat, feeder cattle and live (fed) cattle by taking into account the surge in corn consumption stemming from the boost of mandated ethanol production. Corn is a major carbohydrate-feed component of livestock, with grain sorghum and wheat serving as close substitutes. Moreover, soybean is an important protein-feed component. Being non-stationary data, a vector autoregressive (VAR) model (Sims, 1980) that includes an ‘error correction’ term is applied to the series; likewise known as a vector error correction (VEC) model (Engel and Granger, 1987 and Johansen, 1989). Two separate periods are estimated. The first considers prices prior to recent ethanol mandates. The second includes increased corn consumption from ethanol production, mandated by Energy Policy Acts of 2005 and 2007. Results are consistent with past literature regarding feeder and live cattle prices, among others. More importantly, we find support for the notion of modified feed rations in feedlot operations, given the increased corn prices following the post-ethanol mandated period. The finding is corroborated by two different methods, one via Granger Causality and other via impulse response functions.

description: My alternative dissertation investigates the New England Puritans’ communications media and beliefs in angels, discussing its findings through three different media objects: an online course on the Puritans’ media ecology, a scholarly research essay on Puritan women’s angel sightings and Cotton Mather’s views on them, and a pedagogical essay on teaching Cotton Mather’s Coelestinus. These objects can be read in any order, forming an alinear web, network, or environment of their own. My scholarly essay examines the significance of Cotton Mather’s writings about Puritan women encountering angels in the 1690s, arguing that Mather came to associate angels with the feminine and developed a viewpoint of women as spiritual models, even as he also seemed to have disparaged women’s spirituality in other ways. My pedagogical essay shows how instructors can use Cotton Mather’s Coelestinus to help students come to complex and nuanced understandings of the Puritans, arguing for the value of continuing to teach about the Puritans. Finally, my online course teaches its target audience of young professionals about diverse facets of the Puritan media ecology, through twenty-two audio lectures, discussion questions for each lecture, and group project options. My dissertation argues that the Puritans had a flourishing media ecology, which included psychologically direct, nonlinguistic impulses, shaped particularly by how angels seemed to have communicated with Puritan women. It also argues for teaching about the Puritans through a media lens in order to help students see them in a deeper and more refreshing way.

description: Recently there have been suggestions that for a proper description of hadronic matter and hadronic correlation functions within the NJL model at finite density/temperature the parameters of the model should be taken density/temperature dependent. Here we show that qualitatively similar results can be obtained using a cutoff-independent regularization of the NJL model. In this regularization scheme one can express the divergent parts at finite density/temperature of the amplitudes in terms of their counterparts in vacuum.

description: Extremely low density planets ('super-puffs') are a small but intriguing subset of the transiting planet population. With masses in the super-Earth range ($1-10$ M$_{\oplus}$) and radii akin to those of giant planets ($>4$ R$_{\oplus}$), their large envelopes may have been accreted beyond the water snow line and many appear to be susceptible to catastrophic mass loss. Both the presence of water and the importance of mass loss can be explored using transmission spectroscopy. Here, we present new HST WFC3 spectroscopy and updated Kepler transit depth measurements for the super-puff Kepler-79d. We do not detect any molecular absorption features in the $1.1-1.7$ $μ$m WFC3 bandpass and the combination of Kepler and WFC3 data are consistent with a flat line model, indicating the presence of aerosols in the atmosphere. We compare the shape of Kepler-79d's transmission spectrum to predictions from a microphysical haze model that incorporates an outward particle flux due to ongoing mass loss. We find that photochemical hazes offer an attractive explanation for the observed properties of super-puffs like Kepler-79d, as they simultaneously render the near-infrared spectrum featureless and reduce the inferred envelope mass loss rate by moving the measured radius (optical depth unity surface during transit) to lower pressures. We revisit the broader question of mass loss rates for super-puffs and find that the age estimates and mass loss rates for the majority of super-puffs can be reconciled if hazes move the photosphere from the typically assumed pressure of $\sim 10$ mbar to $\sim 10 \; μ$bar.

description: A multivariate binary choice model is used to examine the climate effects on cattle breed selection across Texas counties. Angus, Brangus, and Brahman are considered in the model. Results suggest that it is more efficient to estimate the binary choice equations jointly than separately. Counties having higher summer temperatures are more likely to choose Brahman and warmer winters increase the likelihood of adopting Brangus and Brahman. Angus price imposes positive effects on both Angus and Brangus. In general, the marginal probability of selecting Angus is much higher than that of Brangus or Brahman.

description: It is shown that difficulties in reconciling the values of the cross section e+e- -> J/psi+eta_c measured at BELLE and calculated within non-relativistic QCD (NRQCD) are caused not by some misinterpretation of the data or other exotic explanations, but by poor applicability of NRQCD to such processes. We use general theory of hard exclusive processes in QCD together with more realistic models of charmonium wave functions, and show that the BELLE result can be naturally explained.

Machine Learning

description: Graph learning focuses on predicting labels or properties of graph-structured data, such as social networks, molecular structures, and citation networks. Unlike traditional data formats, graphs encode both node-level features and edge-based relationships, which makes them complex yet rich sources of information. Traditional graph neural networks typically emphasize individual graph representations, neglecting the relational context that could help with graph learning. In this dissertation, we introduce novel frameworks for graph learning that address limitations in existing graph neural network methods by exploring relationships among graphs, graph augmentations, and intricate relational patterns captured within graphs. We provide new perspectives on graph learning, with implications for applications in games, power systems, and beyond.

description: Category systems are central components of knowledge bases, as they provide a hierarchical grouping of semantically related concepts and entities. They are a unique and valuable resource that is utilized in a broad range of information access tasks. To aid knowledge editors in the manual process of expanding a category system, this paper presents a method of generating categories for sets of entities. First, we employ neural abstractive summarization models to generate candidate categories. Next, the location within the hierarchy is identified for each candidate. Finally, structure-, content-, and hierarchy-based features are used to rank candidates to identify by the most promising ones (measured in terms of specificity, hierarchy, and importance). We develop a test collection based on Wikipedia categories and demonstrate the effectiveness of the proposed approach.

description: We analyze the effect of an emergence of biofuel industry on the Conservation Reserve Program. The government expenditure on Conservation Reserve Program needs to increase dramatically to keep the current scale of CRP program when the biofuel industry is considered. We propose that the development of bioenergy crops on expiring CRP land is a potential way to reconcile the conflict between a sharp increase in government CRP budget and its environmental protection goal. CRP program can also be combined with the Biomass Crop Assistance Program (BCAP) to achieve the goal of environmental protection and low carbon society at the same time.
A construct comparability analysis of cognitive ability tests in different languages
Creators: name: McCreith, Tanya Michelle
Publisher: name: University of British Columbia
Year: 2009

description: This research studies the construct comparability of the Woodcock-Johnson Battery - Third Edition Tests of Cognitive Ability (WJ III COG; Woodcock, McGrew, & Mather, 2001) and the Bateria III Woodcock-Munoz: Pruebas de Habilidad Cognitiva - Third Edition (Bateria III COG; Woodcock, Munoz-Sandoval, McGrew, Mather, & Schrank, in press-b), which are the English and Spanish versions of the same battery, respectively. These are measures of cognitive functioning that purport to be direct counterparts of one another. This study examined the degree of comparability and sources of incomparability of seven tests of cognitive ability that were translated from English to Spanish. The purpose of this study was to determine: (1) whether the dimensionality and structure of each of the selected tests of the WJ III COG and Bateria III COG were the same; (2) whether there were specific items from the selected tests of the WJ III COG and Bateria III COG that function differentially for English- and Spanish-speaking examinees; and (3) whether the sources of differences in constructs being assessed for the two language groups could be identified. Answers to the research questions stated above contributed to evidence relevant for determining the comparability of the inferences based on these test scores for two different language versions. Between the two language versions of the tests, at the scale as well as the item level, the results indicated that there were different levels of psychometric similarities and differences for some of the seven tests that may jeopardize the comparability of scores from these versions.
Precise measurement of CMB polarisation from Dome-C: the BRAIN and CLOVER experiments

description: The characterisation of CMB polarisation is one of the next challenge in observationnal cosmology. This is especially true for the so-called B-modes that are at least 3 order of magnitude lower than CMB temperature fluctuations. A precise measurement of the angular power spectrum of these B-modes will give important constraints on inflation parameters. In this talk, I will describe two complementary experiments, BRAIN and CLOVER, dedicated to CMB polarisation measurement. These experiments are proposed to be installed in Dome-C, Antarctica, to take advantage of the extreme dryness of the atmosphere and to allow long integration time.

description: O objetivo deste estudo foi analisar a influência do PRONAF - Programa Nacional de Fortalecimento da Agricultura Familiar sobre os indicadores agrícolas: produção, área plantada e produtividade das lavouras de subsistências beneficiadas pelo Programa no Estado do Ceará, no período de 1999 a 2005. A pesquisa aplicou análises tabular e gráfica para estudar o comportamento das variáveis. Os resultados registraram que as lavouras de subsistência mais beneficiadas pelo Programa foram: algodão, arroz, cana-de-açúcar, feijão, mandioca e milho. Uma comparação destas lavouras com outras não beneficiadas: banana, castanha de caju e mamona revelou que apesar do financiamento as lavouras beneficiadas pelo PRONAF obtiveram um desempenho inferior ao das não beneficiadas em relação aos indicadores agrícolas analisados. Concluiu-se que a influência do PRONAF no desempenho dos indicadores agrícolas das lavouras de subsistência é muito pequena. --------------------------------------------The objective of this study was to analyze influence the PRONAF - National Program of Fortifies of Familiar Agriculture on the agricultural pointers: production, planted area and productivity of subsistences the farmings benefited for the Program in the State of the Ceará, the period 1999 to 2005. The research applied tabulate analyses and graphical. The subsistences of farmings more benefited by the Program had been: cotton, rice, sugar cane-of-sugar, beans, cassava and maize. A comparison with others benefited not of these farmings: banana, chestnut and mamona disclosed that despite benefited the farmings financing for the PRONAF they had gotten an inferior performance to the one of not benefited in relation to the analyzed agricultural pointers. One concluded that the influence of the PRONAF in the performance of the agricultural pointers of the subsistence farmings is very small.

description: We present two approaches to the dynamics of a quench-induced phase transition in quantum Ising model. The first one retraces steps of the standard approach to thermodynamic second order phase transitions in the quantum setting. The second one is purely quantum, based on the Landau-Zener formula for transition probabilities in avoided level crossings. We show that the two approaches yield compatible results for the scaling of the defect density with the quench rate. We exhibit similarities between them, and comment on the insights they give into dynamics of quantum phase transitions.
