A Replication of “The Experience of Ethical Dilemmas, Burnout, and Stress Among Practicing Counselors”
DownloadSpring 2020
This study is a replication and expansion on the study completed by Mullen, Morris, and Lord in 2017 which aimed to determine how experience and reflection on ethical dilemmas impacts burnout amongst counselors. One hundred, sixty-four counselors completed an in-person survey that measured...

An examination of parent-child dyadic interaction and the impact of a parent-training program designed to support the language development of toddlers diagnosed with autism spectrum disorder (ASD)
DownloadFall 2010
Parents can effectively facilitate positive child behaviour change (Kaiser & Hancock, 2003). Their inclusion as interventionists is an essential component of autism intervention (NRC, 2001) and represents a natural step toward consistent early intervention. However, what constitutes effective...

Assessing stress in western Hudson Bay polar bears using hair cortisol concentration as a biomarker
DownloadFall 2015
The development of novel biomarkers to help assess whether polar bear (Ursus maritimus) health is impacted by long-term physiological stress associated with climate change represents an emerging area of research. With progressively greater reductions in sea ice cover and a corresponding decrease...

Bacterial stimulation of lipid vesicle production in green microalga Dunaliella tertiolecta
DownloadFall 2019
Algae and bacteria form complex interactions through the exchange of bioactive molecules and nutrients. A wide range of phenotypes, and often their very survival, are influenced by these chemically mediated relationships, shaping the ecology and diversity of marine communities. Here we sought to...

Development and Analysis of Magnetic Carbon Nanotube and Microbubble-Assisted High Centrifugation Field Techniques For The Increase of Cell Membrane Permeability
DownloadSpring 2014
To cure diseases at the gene level, therapeutic biomaterials need to enter the cells. However, since the cell membrane is a highly selective structure, its permeability is usually very low. In this thesis, we propose two innovative and efficient methods to increase cell membrane permeability....

Development and use of a gnotobiotic murine model for beef cattle to evaluate competitive exclusion of Escherichia coli O157:H7 using commensal Escherichia coli strains, and to ascertain the impact of physiological stress on the host-bacteria interaction
DownloadFall 2020
Enterohemorrhagic Escherichia coli (EHEC) serotype O157:H7 is an important foodborne pathogen, and cattle are considered the primary reservoir of this bacterium. Research was undertaken to ascertain factors that regulate competitive exclusion of E. coli O157:H7. A gnotobiotic (GB) murine model...

Early life exposure to stress can have life-long effects on an organism. These effects may be detrimental, or they may be adaptive if they allow the organism to develop an adult phenotype which better matches the environment predicted by the stressor. Early life stress influences many traits,...

Effect of Laying Hen Housing Environment and Genetic Strain on Meat Quality and Skeletal Muscle Physicochemical Properties
DownloadFall 2016
Skeletal muscle is an adaptable, multi-faceted tissue that is essential for whole body movement and metabolism. When a production animal is slaughtered, its muscle goes through complex physical and biochemical changes including a shift from aerobic to anaerobic metabolism resulting in the...

Electrocoalescence of Water Droplets in Oil Emulsions: Effect of Electric Fields, Surfactants, and Chemical Demulsifiers
DownloadSpring 2019
Stabilization of water-in-oil droplets during bitumen extraction and refining process poses a major challenge in the oil sands industry. These crude oil emulsions are stabilized by rigid films at water droplet-oil interfaces. The salty water remaining in oil causes equipment corrosion, catalyst...
