Fall 2017
The value of oat (Avena sativa L.) for the producer is a function of both grain yield and quality. Therefore, managing nitrogen fertilizer rates to optimize yield while meeting expected grain quality standards is essential in guaranteeing profitable production. To determine the effect of nitrogen...

Intermediation and Governance of Digital Flows: Canadian Internet Service Providers as Instruments of Public Policy
DownloadSpring 2018
The internet has often had a disintermediating effect, 'disrupting' and circumventing traditional middlemen and gatekeepers. This dissertation examines the related trend of intermediation, or the ascendance of new internet intermediaries and their growing significance in our lives. Among these...

Fall 2017
This study examined how model youth football coaches developed their leadership styles. Six model youth football coaches (M age = 46 years, SD = 6), and one athlete from each stage of the coaches’ careers (early, middle, recent; n = 18, M age = 24 years, SD = 4) were purposefully sampled. Each...

Experimental determination of nitrogen isotope fractionation associated with NH3 degassing at 0-70 ºC
DownloadFall 2017
Ammonia degassing is a common process in natural alkaline water systems (e.g., hydrothermal vents). Nitrogen isotope fractionation factor is an important parameter to quantitatively assess the nitrogen cycle in these systems, but still not constrained yet. In this study, we carried out laboratory...

Understanding the evolution of the membrane trafficking system in diverse eukaryotes through comparative genomics and transcriptomics
DownloadSpring 2018
Single-celled organisms represent the majority of eukaryotic diversity. Recent advances in sequencing technologies have been critical for understanding the evolutionary biology and cell biology of microbial eukaryotes. Comparative genomic analyses have shown that many genes that underlie...

Fall 2017
Model-free off-policy temporal-difference (TD) algorithms form a powerful component of scalable predictive knowledge representation due to their ability to learn numerous counter- factual predictions in a computationally scalable manner. In this dissertation, we address and overcome two...

Genetic variation for nitrogen use efficiency in Canada Western Red Spring wheat (Triticum aestivum L.) under conventional and organic management systems
DownloadSpring 2018
Improved nitrogen use efficiency in cereal-based agricultural systems can contribute to increasing grain production while reducing agriculture-related pollution caused by nitrogen leaching, volatilization and denitrification. Organic agriculture differs to conventional systems in terms of in...

Exploiting the Enhanced Permeability and Retention Effect for the Targeting of Tumors with 18F-SiFA Polymer Nanoparticles
DownloadFall 2017
Over the last several decades great progress has been made in cancer diagnosis and detection. One foundation of this progress has been improved imaging technologies. Among the most promising imaging technologies for cancer detection is Positron Emission Tomography (PET). PET imaging allows for...
