Optimal Mechanisms for Machine Learning: A Game-Theoretic Approach to Designing Machine Learning Competitions
DownloadSpring 2013
In this thesis we consider problems where a self-interested entity, called the principal, has private access to some data that she wishes to use to solve a prediction problem by outsourcing the development of the predictor to some other parties. Assuming the principal, who needs the machine...

Legume-grass forage mixes for maximizing yield and competitiveness against weeds in early establishment
DownloadSpring 2010
A field experiment from 2003 to 2005 at two sites examined the impacts of forage species and legume proportion on forage sward production. Grasses generally established rapidly and out-yielded swards high in legume content, although legumes did improve forage quality. Alfalfa was retained at...

All organisms, including plants, experience variability in the environment which puts pressure on organisms to evolve flexible responses. The study of these responses by organisms falls into the discipline of behavioural ecology. In this thesis, I am interested in the foraging behaviour of plant...

Factors affecting larval growth and development of the boreal chorus frog Pseudacris maculata
DownloadFall 2010
The boreal chorus frog (Pseudacris maculata) is a widespread species but we know little of its ecology. I examined the nature and existence of competitive mechanisms operating between larvae of the boreal chorus frog and wood frog (Lithobates sylvaticus) from field, mesocosm and laboratory venues...

Kura clover (Trifolium ambiguum) is a perennial legume species that has been found to have exceptional persistence in the United States, Australia and New Zealand. There are two challenges that impede the incorporation of Kura clover into pasture mixtures in Alberta. The first is the lack of...

Competition in Arabidopsis thaliana (L.) Heynh., behaviour of Mimosa pudica L. and a new method to characterize roots demonstrated with Helianthus annuus L..
DownloadFall 2016
In this dissertation, I address 5 problems in the discipline of plant ecology: two problems in plant competition, two problems in plant behaviour and one problem in the phenotyping of plant roots. First, we directly test Darwin’s competition-relatedness hypothesis with a pairwise...

Fall 2013
The overall purpose of this dissertation is to identify the demand of fast moving consumer goods (FMCG) and to analyze the issues of brand level competition in FMCG markets product categories at the Canadian retail level. The analysis develops and applies industrial organization and price...

Relationships among diverse root foraging behaviours: understanding plant behavioural types
DownloadSpring 2014
Behaviours capture the functional response of plants to environmental factors. I explore behaviours for twenty co-occurring grassland species in response to common belowground environmental factors (competition, mycorrhizae, heterogeneous and high nutrients) and their relationship to plant...

To compete or cooperate? three essays on the relationship between unions and employee and organizational outcomes: the moderating effect of management's response
DownloadFall 2010
In their highly influential work on the labour market impact of unions termed the collective voice/institutional response model (CVIR), Freeman & Medoff (1984) proposed that whether the union’s monopoly or voice face would prevail greatly depended on the union’s and management’s willingness to...

Grassland plant community assembly: The role of environmental heterogeneity, evolutionary history, competition, and pollination
DownloadFall 2013
Plant community assembly is not a simple process; any factor that can affect the recruitment or coexistence of individuals can alter the outcome (e.g. nutrients, symbionts). In this thesis, I address a diverse subset of these potential factors, focusing on environmental variation, evolutionary...
