The study explored factors associated with English as Second Language (ESL) and English Literacy Development (ELD) students’ performance on the Ontario Secondary School Literacy Test (OSSLT) from three different yet interrelated aspects. These aspects were the relationship between test performance and the characteristics of ESL/ELD students; the relationship between ESL/ELD students’ aggregated school performance and their school-level socio-economic status; and a comparison of ESL/ELD and non-ESL/ELD students’ performance on three test formats in the reading component of the OSSLT (multiple-choice questions, constructed-response questions, and constructed-response questions with explanations). The study was conducted based on 4,311 ESL/ELD students’ test data, their responses to the Educational Quality and Accountability Office’s (EQAO) Student Questionnaire, and the test results of 5,003 non-ESL/ELD students. School-level socio-economic status data from the Education Quality and Indicators Program (EQUIP) were merged with the OSSLT test data. These data were analyzed using exploratory factor analysis, multiple regression and discriminant analysis. The results indicated that e-literacy activities, literature literacy activities...

Animal biovectors can focus nutrients and other substances to particular receptor sites through their natural behaviours and lifecycles, such as during breeding or migration. Since the late 1970s, double-crested cormorants (Phalacrocorax auritus) have experienced a striking population increase in the Great Lakes region. These birds can act as biovectors when they feed in aquatic ecosystems but concentrate waste substances to their small island nesting sites in the Great Lakes. We assessed the current ecological impacts and tracked the long-term influences of cormorants and other avian biovectors using diatoms and inferred chlorophyll-a concentrations from pond sediments of four closely situated island colonies in Lake Ontario. The fossil diatom assemblages in recent sediments of three of the sites record taxa that are characteristic of nutrient-enriched waters as a result of biovector deposits, while the sedimentary chlorophyll-a profiles of these sites demonstrate a rapid increase in primary production, likely due to the sudden onset of nutrient-rich waste inputs following cormorant colonization and proliferation. Two of the study ponds are low-lying and are likely periodically inundated with Lake Ontario water and associated diatoms...

The United Nations recently criticized the Canadian Government for lacking a unified federal policy for child programming; lacking a clear strategy in the development of youth rights, opportunities, and initiatives; and averting accountability as there is no assurance that these programs are effective due to the absence of evaluative methods. The UN went on to highlight that addressing these issues in Canada is particularly important for “vulnerable” youth such as Aboriginal, black, immigrant, and disabled children. Youth- that being anyone between the ages of 15 and 24- have been greatly, if not completely excluded from research that informs public policy and planning, and barred from the opportunity to meaningfully participate in planning processes that affect their lives. This has left industry professionals with a large anomaly when it comes to ensuring inclusive, effective, and sustainable planning practices within communities. Of the limited research that has been conducted, the majority is largely focused on the cognitive capacities of young people when participating within the adult dominated realm of planning. Overwhelmingly, researchers discover that young people do in fact have the ability and motivation to effectively participate in planning...

The use of wind power has become an increasingly attractive energy source as concerns over climate change and non-renewable energy intensify. This report focuses on the largest segment of wind turbine development in Ontario, which is developer-owned turbines on leased private or crown land. The useful life for a modern wind turbine is approximately 20 years, at which point, the facilities must be repowered or decommissioned if economic or social circumstances no longer support the project. Based on the results of applying evaluation criteria to four wind energy Decommissioning Plan Reports, this report provides a number of recommendations for improving the process of planning for decommissioning wind energy facilities in Ontario.

The Ontario Tobacco Control Act of 1994 imposed a total ban on smoking in schools, and on school property for every school in the province. The imposition of this policy created problems for school administrators. For instance, students who were smoking on walkways and properties adjacent to school boundaries, clashed with neighbouring property owners who were angry about the resulting damage and disruption. The enforcement of this policy consumes valuable resources at each school; therefore, knowledge about the impact of the policy is important. If effective, this policy has the potential to improve the health of students over their lifetime, by preventing or delaying smoking behaviour. Alternatively, an ineffective policy will continue to create administrative problems for the school and serve no legitimate purpose. Therefore, knowledge about the impact of the smoking ban policy on students' smoking intentions assists policy makers and school administrators in their understanding of the policy's impact within the schools. This research provided an impact evaluation of the ban on smoking in schools and on school property in Ontario. A total of 2069 students, from five high schools, in the Niagara Region, provided complete responses to a survey...

An essay submitted by Sean O'Sullivan to Professor W.A. Matheson, 25 April 1977. The focus of the essay is stable government, "As one of the chief, if not the predominant, force in giving Confederation its political shape, Ontario helped bring about a central government designed to promote, and dedicated to preserve, stability. In the governing of their own province, the people of Ontario have been faithful to that same goal of stability. Perhaps that steadfast attitude says more than anything else about the political culture of Ontario."

The present study was carried out to test the hypothesis that photosynthetic bacteria contribute a large portion of the food of filter feeding zooplankton populations in Crawford Lake, Ontario. The temporal and spatial variations of both groups of organisms are strongly dependent on one another. 14 By using C-Iabelled photosynthetic bacteria. the ingestion and clearance rates of Daphnia pulex, ~. rosea, and Keratella spp were estimated during summer and fall of 1982. These quantitative estimations of zooplankton ingestion and clearence rates on photosynthetic bacteria comprised an original addition to the literature. Photosynthetic bacteria comprised a substantial portion of the diet of all four dominant zooplankton species. The evidence for this is based on the ingestion and clearance rates of the dominant zooplankton species. Ingestion rates of D. pulex and D. rosea ranged 5 5 -1 -1 - -- 5 - -- 5 from 8.3X10 -1 to 14.6XlO -1 cells.ind. hr and 8.1X10 to 13.9X10 cells.ind. hr • Their clearance rates ranged from 0.400 to 1.000 -1 -1 -1 -1 ml.ind. hr. and 0.380 to 0.930 ml.ind. hr • The ingestion and clearance -1 -1 -1 -1 rates of Keratella spp were 600 cell.ind. hr and 0.40 ul.ind. hr respectively. Clearance rates were inversely proportional to the concentration of food cells and directly proportional to the body size of the animals. It is believed that despite the very short reg~neration times of photosynthetic bacteria (3-8 hours) their population densities were controlled in part by the feeding rates of the dominant zooplankton in Crawford Lake. By considering the regeneration times of photosynthetic bacteria and the population clearance rates of zooplankton...

Switchgrass (Panicum virgatum), a perennial C4 grass species, has the capacity to not only improve the quality of the soil in which it grows but also promote soil carbon storage to offset rising atmospheric CO2. This research investigated soil organic carbon (SOC) dynamics beneath switchgrass using natural abundance 13C and soil carbon fractionation following the establishment of this crop in a native and predominantly C3 plant region in southeastern Ontario. I investigated SOC dynamics by sampling adjacent commercial switchgrass fields and appropriate paired control fields at sites where the time since switchgrass establishment varied from 4-11 years. SOC and natural 13C abundance were measured in paired fields to assess management-induced changes in the quantity, source, and turnover time of soil carbon. To better elucidate carbon cycling dynamics over a relatively short time since switchgrass establishment, multiple soil fractionation techniques were applied to better understand carbon dynamics of soil organic matter with various mean residence times. Establishment of switchgrass results in marginal increases in SOC, primarily at sites where intensive soil management (i.e. tillage) practices preceded switchgrass establishment. Changes were observed in some of the more labile SOC pools...

The Ontario Tories' 42-year hegemony in government (1943-1985) was wrought through clever policies which often utilized Crown institutions to promote prosperity or to oblige or mollify vying interests. Ousted in 1985, though, they used their time in opposition to revise the Tory doctrine. In the 1995 election, the Tories emerged a tougher, more truculent group quite unlike their predecessors. Campaigning on their Common Sense Revolution (CSR) platform, they promised to eliminate red tape and vowed to obliterate all ostensible economic barriers which were impeding commerce in the province. In the CSR, the Tories identified Ontario Hydro (OH), the province's lauded publicly-owned power monopoly, as a troublesome and inefficient Crown entity which required fundamental reform. Portions of OH, they hinted, would likely be sold. Once elected, the Tories worked hurriedly to demolish OH and destroy public power in Ontario. For nearly 100 years, OH proved a pivotal component within the province's political economy for its provision of affordable, reliable power and its function as a policy tool to incite and direct development. A Tory government fought to instigate public power in the early 1900s and, in the late 1900s, a Tory government was fighting vigorously to rescind it. Why would they now renounce Crown power? It is the intent of this thesis to elucidate the Tory government's involvement in the transformation of Ontario's electricity industry from 1995 to 2003. Distinguishing electricity as a special...

The demand for home care increased dramatically in Canada in the past decade. This was because more patients were discharged from hospital, more emphasis was put on health care at the home and community levels, the continuing aging of the population, advancements in technology, and the adoption of a more cost-effective strategies. Though home care is still not a part of Canadian Health Act (CHA) and there are no national regulations for home care, people value the significance of home care. Home care is now one of the fastest growing sectors in Canada’s health care system. With a focus on the elderly population in the province of Ontario, this thesis uses data from the Canadian Community Health Survey (CCHS cycle 1.1, 2.1 and 3.1) to examine utilization patterns of home care considering social and geographical factors, the variation within home care service provision, and unmet home care need. The major findings of the thesis are that seniors with poorer health status, older age, female, with lower household incomes, marital status widowed/separated/divorced/single/never married, and living in urban areas are more likely to use home care. At the same time, seniors who are older, with poorer health status, and suffering from chronic condition are in a more vulnerable position to receive the home care they need. A large amount of responsibility was shifted to informal caregivers due to the budget constraints and the policy bias of the government. Access to home care is unequal on a geographical scale. Seniors living in rural and remote areas tend to have more unmet home care needs than seniors living in urban areas. People living in rural northern regions in Ontario have the least access to home care. Also...

The Ontario Clean Water Act (2006) mandated that eight and two municipal drinking water intakes in the Cataraqui Region Conservation Authority (CRCA) and the Ganaraska River Source Protection Agency (GRSPA) jurisdictions respectively, be protected from contaminants released into the surrounding waters through the delineation of Intake Protection Zones (IPZs). Toward these objectives, the Estuary and Lake Computer Model (ELCOM) was applied to simulate the hydrodynamics and contaminant transport in the eastern Lake Ontario and upper St. Lawrence River. Model hydrodynamics were comprehensively validated against field data collected during April-October, 2006. The flow was found to be predominantly wind induced in the southwestern lacustrine portion of the domain and hydraulically driven in the northeastern riverine portion with storm events resulting in river flow reversals. The modeled surface currents were applied to delineate IPZs surrounding the drinking water intakes. Passive tracers were simulated as surrogates for combined sewer outflows, tributary flows, municipal/wastewater and industrial discharges identified by CRCA as threats to drinking water intakes. Wind was found to be the most dominant forcing to transport contaminants...

This dissertation examines the role of memory in the construction of small-town Ontario in the work of a number of Ontario writers. After an initial overview of the vexed position the small town holds in Canadian and Ontarian cultural discourse, this dissertation then examines the role of distance - temporal, spatial, and cultural - in memorial reconstructions of small-town pasts, and claims that this distance is essential to nostalgic visions of the small town. This dissertation does not discuss the small town as merely an idyll or anti-idyll, but analyzes the effect of something Leo Marx calls the “pastoral design,” defined as the “larger structure of thought and feeling of which the ideal is a part” (24). The effect of this structure is most apparent in Stephen Leacock’s Sunshine Sketches of a Little Town, and this dissertation argues that Leacock’s Mariposa is the product of melancholics daydreaming of a better small-town past in order to soothe their contemporary urban anomie; however, Leacock also reveals the decidedly ambivalent effect the urban sphere has on its own nostalgic image. Chapter Three examines Sunshine Sketches’ influence on Deptford in Robertson Davies’ Fifth Business; Deptford is at once an acknowledgement of...

Lake Ontario's outflow and level have many effects on surrounding communities and down stream populations in northeastern United States. Since many people and industries rely on Lake Ontario for recreation, power generation, and navigation, to name a few, significant effort has focused on forecasting the water levels and water supplies. This analysis concentrates on forecasting the water supply into Lake Ontario. Independent time series models were developed for (1) Lake Ontario's supply from Lake Erie and for (2) the remaining "local" supply, also termed net basin supply, over the period from 1900 through 1992. These two models were combined to produce total supply predictions for Lake Ontario. In comparison, this model performed slightly better than another time series model based solely on past values of the Lake's total supply.

Computer-based, mathematical models that simulate spatially distributed and time dependent environmental processes are increasingly recognized to provide diagnostic and productive outputs for the assessments of environmental factors. Mathematical models have been utilized since 60's to study the water quality, the circulation structure and the seasonal changes of large water bodies such as the Great Lakes. Analysis of changes in water quality related to seasonal cycles such as the formation and the propagation of the thermal bar requires spatial and temporal models, with high resolution. The overall objective of this study was to integrate geo-referenced site-specific spatial data to a 3D hydrodynamic model (ALGE) and compare the outputs with geo-referenced remotely sensed thermal imagery. The motivation of this work is based on the idea that the spatial data provides a significant advantage of equipping the model with site specific data to manipulate site specific circulation patterns. Further since the input is geo-referenced and site specific, the output can be directly compared to geo-referenced remotely sensed imagery for model validation. Thus, the aspect of integration of spatial data to hydrodynamic models is an obvious and promising approach to study lake-wide hydrodynamic processors and seasonal changes. A specific objective of the study was to examine how different spatial patterns and weather conditions influence the formation and the propagation of the thermal bar temporally and spatially. Several preliminary studies were conducted on square lakes and lakes with false bathymetric profiles...

Sediment cores were obtained from 15 lake stations representing the three major basins and the Inshore Zone of Lake Ontario. Cores were sectioned for characterization of the surface sediments according to inorganic P chemical mobility. Physical mobility was characterized by measurement of P release from intact cores incubated under controlled laboratory conditions. The proportions of potentially chemically mobile inorganic P were usually high (30 to 60%) in the central basin sediments and low (2 to 8%) for the inshore zone sediments. Although the amounts of inorganic P desorbed after three successive equilibrations (in .lM NaC1) of Lake Ontario sediments represented only 3 to 17% of the potentially mobile inorganic P, sufficient inorganic P was desorbed to restore a large part of the original interstitial inorganic P concentrations. Interstitial inorganic P (mobile P) concentrations ranged from 14 to 1280 Ng/l and were higher than dissolved inorganic P concentrations in the overlying water. Diffusion rates estimated from the range of observed interstitial inorganic P values ranged from about 0.05 to 0.6 mg m-‘ day-’ and were in agreement with the range of 0.03 to 0.8 mg m-2 day-’ estimated from P release from intact cores incubated under controlled laboratory conditions. Based on an inorganic P flux of 0.2 mg estimated annual contribution of inorganic P to Lake Ontario water is equal to about 10% of the external P loading.; Enviromental Protection Agency

Settlements have historically taken root along bodies of water; however, lands adjacent to water bodies can face the risk of riverine flooding. In Southern Ontario, responsibility for representing provincial interest for plan input and review with respect to flooding hazards have been delegated to conservation authorities. While development and site alteration in the floodplain is generally not permitted or restricted, development may occur in certain areas with a reduced risk. These areas are referred to as the “flood fringe”, and the type of planning employed in such a mechanism is called the “two zone concept”. In this research, planning policies used by conservation authorities for the two zone concept are examined by answering the research questions, “how is the two zone concept of floodplain management applied by conservation authorities in Southern Ontario?” and “what are the strengths and weaknesses of the two zone concept of floodplain management as applied in Southern Ontario?” To answer the research questions, a multiple case study approach was employed. Through a literature review, components that make a high-quality natural hazard plan were examined and an evaluation framework was developed to compare planning documents that contained policies regarding the two zone concept. Planning documents released by Conservation Halton (2011)...
