Associations and Interactions between Retail Food Environments, Food Gentrification, and Neighbourhood-level Intersectionality in Toronto, Canada
(University of Waterloo, 2021-09-28)Diet-related disease and food insecurity are growing problems in Canada and globally. Over the last decade, prevalent rates of obesity and type 2 diabetes have increased across the country and Toronto currently has the ... -
Associations between Greenspace and street Crimes in Toronto: Evidence from a spatial analysis study at dissemination area level
(University of Waterloo, 2020-06-03)Introduction: Earlier criminologists have explored various factors generating or attracting crime in urban cities coupled with crime studies focusing on the influence of social, built and natural environments in urban ... -
The associations between insulin, hypoglycemia, and dementia: Combating threats to internal validity in a series of population-based cohort studies
(University of Waterloo, 2023-05-01)Although the association between type 2 diabetes and dementia is recognized, findings from the epidemiology literature on the effect of insulin and one of its side effects, hypoglycemia, are less clear. The currently ... -
Associations between Oil Additives in Base Oils Probed by Pyrene Excimer Fluorescence
(University of Waterloo, 2017-10-23)A recently developed method based on pyrene excimer fluorescence was used to probe the interactions of important polymeric oil additives. First, three ethylene-propylene (EP) copolymers representative of viscosity index ... -
Associations of Moral Disengagement, Passion, and Competitive Anger and Aggressiveness with Attitudes toward Performance Enhancing Drugs in Sport
(University of Waterloo, 2015-01-05)The main purpose of the study was to explore relationships between moral disengagement in sport and attitudes toward performance enhancing drugs. Additionally, the purpose was to explore specific mechanisms of moral ... -
Astra: Evaluating Translations from Alloy to SMT-LIB
(University of Waterloo, 2018-12-21)We present a variety of translation options for converting Alloy to SMT-LIB via Alloy's Kodkod interface. Our translations, which are implemented in a library that we call Astra, are based on converting the set and relational ... -
Asylum and the Politics of Irregularization: Refugee Claimants and Toronto’s Everyday Places
(University of Waterloo, 2018-06-25)While Canada is touted as having a universal healthcare system, not all of its residents have access to it, particularly precarious status noncitizens such as refugee claimants. As a signatory of international refugee ... -
Asymmetric Alkenylation of Enones and Other α,β-Unsaturated Carbonyl Derivatives Using Chiral 3,3′-Disubstituted Binaphthols and Boronates
(University of Waterloo, 2009-05-22)Various α,β-unsaturated carbonyl compounds and derivatives were explored in order to expand the range of substrates for the 1,4-addition of alkenylboronates using 3,3′-disubstituted binaphthols. Enones 2.60 were examined ... -
Asymmetric Conjugate Addition of Arylboronates to α,β-unsaturated Enones Catalyzed by Substituted Binaphthols
(University of Waterloo, 2009-10-01)Conjugate addition reactions are one of the most widely used carbon-carbon bond forming reactions in organic synthesis. This reaction can form a chiral center and can be used for the synthesis of structurally complex ... -
Asymmetric Conjugate Addition of Boronates to N-Acylimines and β-Silyl-α,β-unsaturated Ketones Catalyzed by 3,3'-Disubstituted Binaphthols
(University of Waterloo, 2009-01-23)In order to extend the scope of asymmetric conjugate alkenylation catalyzed by 3,3′-disubstituted binaphthols, two classes of compounds were examined. Asymmetric 1,4-addition of alkenylboronates onto N-acylimines was ... -
Asymmetric Conjugate Additions of Boronates to α,β-Unsaturated Trifluoromethyl Ketones and Strategies Towards Asymmetric Conjugate Additions of N-Boc-Pyrrole Boronic Acid
(University of Waterloo, 2016-08-24)An important class of organic molecules are those that contain fluorine. Fluorinated molecules have found widespread use in medicinal chemistry, as well as in agrochemicals. This is due to the ability of fluorine to act ... -
Asymmetric dependence and its effect on helping behaviour in work groups
(University of Waterloo, 2010-01-20)A case study of two software teams in a large American software company revealed evidence of a power imbalance and intergroup conflict. The case study was used to generate questions about the effects of task-dependence ... -
Asymmetric Synthesis using 3,3'-Disubstituted Binaphthol-modified Boronates
(University of Waterloo, 2006)A number of 3,3'-disubstituted binaphthol-modified allylboronates (<strong>2. 42a-m</strong>) were prepared from the reaction between triallylborane and the corresponding 3,3'-disubstituted binaphthols. These chiral ... -
Asymptotic Distribution of the Optimal Value in Random Linear Programs: Application to Maximum Expected Shortfall
(University of Waterloo, 2020-10-08)The properties of risk measures are of fundamental concern in quantitative finance, particularly in times of uncertainty. We study the behaviour of the asymptotic distribution of the maximum expected shortfall of a portfolio ... -
Asymptotic Distributions for Block Statistics on Non-crossing Partitions
(University of Waterloo, 2014-01-23)The set of non-crossing partitions was first studied by Kreweras in 1972 and was known to play an important role in combinatorics, geometric group theory, and free probability. In particular, it has a natural embedding ... -
Asymptotic Estimates for Rational Spaces on Hypersurfaces in Function Fields
(University of Waterloo, 2010-06-29)The ring of polynomials over a finite field has many arithmetic properties similar to those of the ring of rational integers. In this thesis, we apply the Hardy-Littlewood circle method to investigate the density of rational ... -
Asynchronous Joint Source-Channel Communication: An Information-Theoretic Perspective
(University of Waterloo, 2014-09-15)Due to the increasing growth and demand for wireless communication services, new techniques and paradigms are required for the development of next generation systems and networks. As a first step to better differentiate ... -
Asynchronous Optical Flow and Egomotion Estimation from Address Events Sensors
