Evaluating the Effects of a Fire Disturbance on Native Alvar Vegetation: Implications for Woody Species Management and Conservation of Open Alvar Habitat
(University of Waterloo, 2018-10-22)The decline and loss of certain habitat types can be attributed in some part due to a change of disturbance mechanisms or fire exclusion. This is of particular concern for globally-rare open alvar community types, and the ... -
Evaluating the Effects of Grain Size and Divalent Cation Concentration on the Attenuation of Viruses and Microspheres through Crushed Silica Sand
(University of Waterloo, 2006)Over the last decade in North America, an increasing number of microbiological drinking water regulations have been used to manage groundwater resources that are potentially influenced by surface water. Regulations such ... -
Evaluating the Effects of Spalling on the Capacity of Reinforced Concrete Bridge Girders
(University of Waterloo, 2011-09-01)Corrosion of the reinforcing steel is a primary deterioration mechanism for reinforced concrete bridges. Heavy use of de-icing salts is believed to be a major contributor in Ontario to severe girder soffit spalling in ... -
Evaluating the effects of strain selection on the attenuation of Bacillus subtilis spores through saturated porous media
(University of Waterloo, 2013-10-02)Increasingly stringent water quality regulations concerning microbiological parameters govern the use of groundwater resources that are vulnerable to mixing with surface waters. These drinking water sources are at higher ... -
Evaluating the Efficacy of Implicit Authentication Under Realistic Operating Scenarios
(University of Waterloo, 2016-08-10)Smartphones contain a wealth of personal and corporate data. Several surveys have reported that about half of the smartphone owners do not configure primary authentication mechanisms (such as PINs, passwords, and fingerprint- ... -
Evaluating the Estrogenicity of Municipal Wastewater Effluents
(University of Waterloo, 2013-05-02)Municipal wastewater treatment plants (MWWTPs) are point sources of environmental contamination that can cause adverse effects on fish species exposed to their effluents (MWWEs). Contaminants, such as endocrine disrupting ... -
Evaluating the Governance of Sustainability Reporting: Assessing Mandatory and Voluntary Sustainability Reporting Policies and Practices Around the World
(University of Waterloo, 2015-09-15)Sustainability reporting (SR) is the practice of communicating environmental, social, and economic information and initiatives of a company (largely non-financial) to their stakeholders. This practice has been inspired by ... -
Evaluating the Impact of Changes in School-Based Tobacco Interventions Among Never Smokers Between Year 2 and Year 3 of the COMPASS Study
(University of Waterloo, 2016-07-07)Objective:To examine how changes in school-based tobacco programming within a school influenced smoking susceptibility and smoking initiation outcomes among a sample of grade 9 to 12 students over time. Methods: This study ... -
Evaluating the Impact of Changes to School-Level Alcohol Prevention Policies and Programs on Youth Binge Drinking: A Longitudinal Analysis of the Year 2 and Year 3 Data of the COMPASS Study
(University of Waterloo, 2016-06-15)Objective: The purpose of this study was to investigate the effectiveness of alcohol prevention policies and programs implemented in a linked sample of Ontario COMPASS high schools in reducing youth binge drinking over ... -
Evaluating the Influence of Flooding on Aquatic Food-webs in Basins of the Peace-Athabasca Delta Using Isotopic Tracers
(University of Waterloo, 2010-06-18)Periodic flooding has been widely believed to serve an important role in maintaining water levels and productivity of aquatic basins in floodplain landscapes. Here, I analyze four basins of contrasting flood frequencies ... -
Evaluating the Progress of Municipal Natural Asset Management through Monitoring & Evaluation
(University of Waterloo, 2023-09-29)Contemporary environmental and land-use planning in many Canadian municipalities is challenged with two key problems that have grown with increasing urban development: 1) natural ecosystems decline and 2) grey infrastructure ... -
Evaluating the Prospective Benefits of Physical Demands Description (PDD) Data Created from Job Simulations
(University of Waterloo, 2020-02-12)A physical demands description (PDD) is a document that results from the systematic procedure to quantify, and evaluate all of the physical and environmental demand components of all essential and non- essential tasks of ... -
Evaluating the Retrofit of Highway Bridges Using Fluid Viscous Dampers
(University of Waterloo, 2012-01-23)Highway bridges function as the arteries of our society. Hence, it is essential that they remain operational following an earthquake. Unfortunately, a significant number of bridges worldwide, including in Canada, were ... -
Evaluating the role of local climate change on reduced freshwater availability at the Peace-Athabasca Delta using paleolimnology
(University of Waterloo, 2022-06-02)Abundant small, shallow lakes across northern freshwater landscapes are particularly sensitive to alteration of hydrological processes, which makes them vulnerable to multiple potential stressors. At the Peace-Athabasca ... -
Evaluating the Speed and Accuracy of Touch Input at the Edge of a Table
(University of Waterloo, 2019-12-11)Tables, desks, and counters are often nearby, motivating their use as interactive surfaces. However, they are typically cluttered with objects. As an alternative, we explore touch input along the 'edge' of table-like ... -
