The effect of removing examinees with low motivation on item response data calibration
(2014-01-22)Many item-response models (IRM) used to estimate student abilities and test item parameters in large-scale assessments (LSA) do not account for the effect of student low motivation. This effect may pose a threat to the ... -
The effect of secoisolariciresinol diglucoside on oxidative stress and inflammation in cardiac iron overload
(2013-02-01)Chronic cardiac iron overload directly correlates with cardiac dysfunction and may ultimately cause heart failure. Although recent studies have suggested that altered calcium homeostasis and increased reactive oxygen ... -
The effect of sociodemographic and health system factors on the association between multimorbidity and colorectal cancer survival
(2021)This thesis aimed to assess the effect of multimorbidity (MMB) on colorectal cancer (CRC) patients’ survival and explored whether sociodemographic and health system factors affected this relationship or not. This thesis ... -
The Effect of Spring Loaded Single-Hip Support Cane Mechanisms on Upper and Affected Lower Limb Ground Reaction Forces, Muscle Activity, and Self-perceived Ease of Use
(2016)The primary purpose of this study was to determine the effect of commercial spring loaded single-tip canes on ground reaction forces, impulse, and EMG activation in the upper limb during ambulation. Ground reaction ... -
Effect of sulfate content on the evolutive fracture behavior and properties of fiber-reinforced cemented paste backfill
(2022)Backfilling technology is utilized globally to improve ore recovery, reduce mine-generated waste, and provide stability to underground voids. Cemented paste backfill (CPB), a mixture of mine tailings, cement binder, and ... -
The effect of variable type of practice on one handed catching in children with developmental disorders
(2017)Children with developmental disorders, such as DCD, struggle with interceptive tasks like ball catching. These problems may be due to less than optimal abilities to coordinate and control actions at intra- and inter-limb ... -
The effect of vertical internals on the hydrodynamics and phase dispersions in bubble columns: CFD simulation and population balance model
(2018)Vertical internals are widely installed in the bubble columns as heat exchangers or illuminating tubes. This research aims to investigate the effect of dense vertical internals (rods) on the performance of bubble columns. ... -
The Effect of warm-ups and elevated oxygen consumption on running performance in trained collegiate distance runners
(2014-01-22)The mobilization hypothesis (Andzel & Gutin, 1976) states that starting a performance with an elevated baseline oxygen consumption will improve performance by reducing the oxygen deficit at the beginning of the task, ... -
The effectiveness of a group-based tutorial direct instruction program for long-term foster care children: a randomized controlled trial
(2013-02-01)Children in foster care are frequently behind in educational achievement (Flynn, Ghzal, Legault, Vandermeulen, & Petrick, 2004) and perform below grade level (Trout, Hagaman, Casey, Reid, & Epstein, 2008 for a review). ... -
The Effectiveness of environmental communication with scuba divers : a case study comparing the curricula of BSAC, PADI, and SSI entry-level certification courses
(2012-11-10)The purpose of this study was to determine the effectiveness of the environmental communications contained in novice certification course manuals. This was accomplished by reviewing the effectiveness of these communications ... -
The effects of a reduced-exertion high-intensity interval training protocol on measures of cardiovascular and metabolic health in physically inactive individuals
(2020)Cardiometabolic diseases such as diabetes and cardiovascular disease are a growing threat to the quality of life of the population. Exercise is a frontline approach to treat and prevent cardiometabolic disease and its ... -
Effects of a second wood ash application to soil on Picea mariana (Mill.) B.S.P. and Picea glauca (Moench) voss growth and foliar nutrition and soil chemistry
(2022)As the Canadian biomass energy sector grows, so too does its production of by-products such as wood ash from the combustion of wood biomass for energy. Wood ash can be land applied with the goal of increasing the ... -
Effects of a virtual reality intervention on postural adaptation of children with movement and balance problems
(2012)The purpose of this study was to examine the effects of a 20-session Wii Fit intervention on postural adaptation of 10 children with movement and balance problems (M = 8.50 years; SD = 1.27 years). The children’s balance ... -
Effects of aging on the neural networks underlying visuomotor adaptation
(2016)Visuomotor adaptation is the ability to correct movements in response to an error and becomes increasingly important during the aging process when assistive devices may become necessary. Neuroimaging has observed age-related ... -
Effects of antipsychotic medications on older adults with dementia in Canadian complex and long-term care facilities / by Sarah Worobetz.
(2014)Dementia is a neurodegenerative disease that involves progressive cognitive and functional decline. Symptoms vary and commonly include behaviour and psychological disturbances that can result in patients being prescribed ... -
The effects of bilateral ankle bracing and sex on swing block jump height, agility, and sport related anxiety in volleyball players
(2023)Ankle braces are commonly worn in the athletic community both as a method of rehabilitation after sustaining an ankle injury, and prophylactically to prevent an injury. Within court sports such as volleyball, athletes ... -
The effects of climate change on the growth and spawning phenology of fishes in aquatic boreal environments
(2022)Global climate change is occurring and observed warming patterns have had significant impacts on aquatic environments as trends in water temperature are closely related to trends in air temperature. In ectothermic organisms ... -
