The stereochemical impact of chiral ionic liquids on [2+2] photochemical cycloadditions and aldol reactions
(2020)Eight chiral ionic liquids have been prepared for use as solvents to test whether they can induce enantioselectivity in both photochemical [2+2] cycloadditions and aldol reactions using a variety of starting materials. ... -
Stigma associated with seeking help for psychological distress: how public and self-stigma, help-seeking attitudes and intent, self-compassion, and empathy relate
College and university students experience high levels of psychological distress and would likely benefit from accessing mental health services. However, the stigma associated with seeking help as well as the stigma ... -

Stories of practice : preservice teachers' perceptions of information and communications technology
(2009-05-28)This thesis investigates the perceptions of information and communications technology (ICT) held by four preservice teachers as they engage in their first field-based practicum. Perceptions result from interactions between ... -
Stories of the cystorhood: exploring women’s experiences with Polycystic Ovarian Syndrome: implications for education, self-perception, and medicalization
(2016-01-05)The overarching purpose of this study is to explore the experiences of women with PCOS in more detail to provide further knowledge of the syndrome, to educate others, and reduce stigma – for all women, with or without ... -
Strategies to prevent falls in the elderly: effect of a 10-week Taiji training program on proprioception, functional strength and mobility, and postural adaptation
(2015-06-15)The impact of elderly falls on the Canadian health care system is widespread. Balance and motor coordination are commonly affected during the aging process due to declining proprioception (Ribeiro & Oliveira, 2007). In ... -
Strategies to reduce the decline of wild bumble bees in North America: are they working?
(2020)Bumble bees are major pollinators of the world’s agricultural crops and wild plants and, as such, play a key role in maintaining economic prosperity and biodiversity. The decline of wild bumble bees in North America has ... -
Stratigraphic architecture of a paleoproterozoic iron formation depositional system : the Gunflint, Mesabi and Cuyuna iron ranges
(1996)Understanding iron formation depositional processes has been hindered by the lack of precise modern analogues. However, by combining a regional basin analysis of sedimentary and volcanic rocks surrounding an iron formation ... -
Stratigraphy of the western Lake St. Joseph greenstone terrain, Northwestern Ontario
(1981)The western Lake St. Joseph area in Northwestern Ontario is underlain by Archean metavolcanic and metasedimentary rocks. The strata, referred to as the Lake St. Joseph Group comprise three formations representative of ... -
Stratigraphy of two late paleozoic basins : implication for the timing of final emplacement of the Meguma terrane
(1990)Paleoraagnetic studies indicate the Meguma terrane's final emplacement occurred between the Mid-Devonian and Early Permian. Lithostratigraphic units near the boundary of the terrane were investigated in order to provide ... -
Stratigraphy, structure and metamorphism of Archean rocks at Rainy Lake, Ontario
(1980)The rocks of the Rainy Lake area have been deformed during three distinctive episodes. Minor structures provide the geometry which characterizes each episode. The youngest structures include regional faults, a crenulation ... -

Structural and stratigraphic study of the Keewatin-type and Shebandowan-type rocks west of Thunder Bay, Ontario
(1985)Detailed mapping was carried out in the Shebandowan Lakes area and eastward to the Kaministiquia River to study the structural and stratigraphic relationships between the Keewatin and Timiskaming rocks (herein referred ... -
Structural determinations by analytical analysis of 7-phosphanorbornadiene derivatives and amino acid enantiomers
(2000)The purpose of Chapter 1 is to create a bicyclic, two-coordinate phosphorus derivative in the form of a 2,3-benzo-l,4,5,6-tetraphenyl-7-phosphanorbomadiene anion and measure its experimental 3,P NMR chemical shift. This ... -
Structural fire performance of bolted glulam beam-to-column concealed connections
(2018)Recent increased interest in the application of engineered-wood products, such as glued-laminated (glulam) timber and cross-laminated timber (CLT), in the Canadian building construction market has prompted amendments to ... -
