Differential Vulnerability To Debris Flow Hazard In Two High Mountain Communities Of The Karakoram Himalaya, Northern Pakistan, Shauna Flanagan Jan 2003

Differential Vulnerability To Debris Flow Hazard In Two High Mountain Communities Of The Karakoram Himalaya, Northern Pakistan, Shauna Flanagan

Theses and Dissertations (Comprehensive)

This thesis presents the findings of a comparative study of vulnerability, coping and risk-averting strategies and social responses to environmental hazards, particularly debris flow and flooding hazards, in the Northern Areas of Pakistan. Two small village-scale settlements, the prevailing form of community in the region, were selected as case studies and are described in detail. The villages exhibit a comparable subsistence agro-pastoral economy and socio-cultural organization reflecting similarities in environmental opportunities and constraints, historical processes and religious beliefs. However, they differ greatly in their proximity to commercial centres and in the rate at which modernization processes are being introduced and …

Variability Of Metals In Soils In The Sudbury Area (Ontario), Vera Spektor Jan 2003

Variability Of Metals In Soils In The Sudbury Area (Ontario), Vera Spektor

Theses and Dissertations (Comprehensive)

Industrial development influences the natural and human environment. At the local scale, the most intensive industrial pollution is in the area of factories and industrial centers. Industrial pollution is concentrated in soil and vegetation (then, using water systems and trophic chains it may enter all ecosystem components). The industrial pollution of the Sudbury region includes mostly sulfur dioxide and heavy metals. The main goal of this study was to examine spatial variability in metal distribution in soil for the Sudbury area. Objectives of the work were to describe metal distribution depending on geographic factors such as topographic location, vegetation cover, …

The Relationships Of Vegetation And Bird Communities With Landforms And Geomorphic Processes On The Central Niagara Escarpment (Ontario), Robert John Milne Jan 2003

The Relationships Of Vegetation And Bird Communities With Landforms And Geomorphic Processes On The Central Niagara Escarpment (Ontario), Robert John Milne

Theses and Dissertations (Comprehensive)

This study has examined the relationships between geomorphic form and process, vegetation composition and dynamics, and avian populations for landscapes in the central Niagara Escarpment, Southern Ontario. This includes an area extending from Speyside Conservation area near Milton to Mono Cliffs Provincial Park north of Orangeville. Data was collected for geomorphic form and process parameters, vegetation species and structural parameters, and avian species. The physical parameters included a combination of landform characteristics including slope angle, aspect, and landscape position and geomorphic processes, such as creep and debris slides, measured as a level of disturbance. Human levels of disturbance were also …

The Meaning Of Engagement: An Exploration Of Generativity In The Domain Of Politics, Sean Curtis Cameron Jan 2003

The Meaning Of Engagement: An Exploration Of Generativity In The Domain Of Politics, Sean Curtis Cameron

Theses and Dissertations (Comprehensive)

Survey research has raised concerns over recent declines in political participation (Putnam, 2000). However, there has yet to be much research examining reasons for this from a narrative, life history perspective. In the current study, we examined intensive interviews of 94 midlife adults from the MacArthur Foundation Study on Successful Midlife Development, for levels of generative concern using the Loyola Generativity Scale, as well as political behaviours, values and beliefs using measures developed by the authors. This exploratory analysis focused on the accounts that men and women gave of political involvement, as well as predictors of these patterns. Generativity was …

Computer Implementation In Education: Hearing The Educator's Voice, Julie Lynn Mueller Jan 2003

Computer Implementation In Education: Hearing The Educator's Voice, Julie Lynn Mueller

Theses and Dissertations (Comprehensive)

Computer technology is pervasive in education systems around the world. Although computers are now available in almost every school, that presence has not guaranteed the use of computers as part of the instructional repertoire of educators. This thesis is an investigation of the factors that affect implementation of computers from the perspective of educators across a school board. Fifty-four randomly selected educators (37 elementary and 17 secondary) completed a written survey assessing computer access and use, predictors of integration, prevalence of barriers and supports, and, recommendations from the educators themselves. Results indicated that computers are indeed available and that educators …

The State Of Our Union: Appraisals Of Romantic Relationships, Stephen Allan Michael Gallant Jan 2003

The State Of Our Union: Appraisals Of Romantic Relationships, Stephen Allan Michael Gallant

Theses and Dissertations (Comprehensive)

How do romantic partners determine if they are happy in their current relationship? What standards do they use when appraising their romantic relationship? The present thesis examines people’s preferences among various comparison standards (social comparisons, temporal past comparisons, temporal future comparisons and previous relationship comparisons) for relationship appraisal, the direction in which people prefer to make various relationship comparisons and the reported and actual impact of these comparison standards on relationship appraisals. The present research also examines the hypothesis that certain relationship beliefs and characteristics (controllability and satisfaction) affect how one interprets these comparison standards. In study 1, 140 undergraduate …

French And English Word Reading And Word Decoding Performance In Bilingual Children: How Are Phonological Processing Skills Related?, Catherine Adèle Lafrance Jan 2003

French And English Word Reading And Word Decoding Performance In Bilingual Children: How Are Phonological Processing Skills Related?, Catherine Adèle Lafrance

Theses and Dissertations (Comprehensive)

The French (L1) and English (L2) reading development of bilingual children in French schools was examined using measures of oral language proficiency, letter-name and letter-sound knowledge, phonological processing (phonological awareness, naming speed and working memory), and word decoding over an eight month period. At Time 1 (Senior Kindergarten), a series of multiple regressions indicated that, when controlling for oral language proficiency, letter name knowledge and non-verbal reasoning, L1 phonological awareness was the only consistent and unique predictor of French and English word reading and word decoding performance. At Time 2 (Grade 1), French and English phonological awareness were consistent and …

Looking Forward To Fitness: The Effects Of Time Perception On Exercise Behaviour, Lianne Mclellan Jan 2003

Looking Forward To Fitness: The Effects Of Time Perception On Exercise Behaviour, Lianne Mclellan

Theses and Dissertations (Comprehensive)

Previous research has shown that people induced with a future-oriented time perspective were more likely to adhere to an exercise program because they were focused on the benefits of exercise and therefore better able to overcome short-term (ST) costs. The current research aimed to extend these findings by examining time perception—how close or distant the future benefits of exercise subjectively feel. Three studies examined participants’ perceptions of the ST and long-term (LT) benefits of exercise on their motivation to be physically active and their subsequent exercise behaviour. Study l found that having a future time perspective was related to higher …

Effect Of Conditioned Taste Avoidance Learning On Elevated Plus Maze Performance As A Measure Of Potentiated Fear, Shadna Rama Jan 2003

Effect Of Conditioned Taste Avoidance Learning On Elevated Plus Maze Performance As A Measure Of Potentiated Fear, Shadna Rama

Theses and Dissertations (Comprehensive)

The terms conditioned taste aversion and conditioned taste avoidance are often used interchangeably in the literature; however considerable evidence indicates that they may represent independent processes. Recent studies have demonstrated that conditioned taste aversion is mediated by conditioned sickness; however the mechanism(s) responsible for the establishment and expression of conditioned taste avoidance remains unknown. An early theory suggests that a taste that has been previously paired with a drug produces avoidance of that taste because it elicits some novel change in physiological state which signals danger to the rat. The emotional state produced may be one of conditioned fear. The …

Driving Without A Map: Father-Son Sexual Health Communication, Alison Elizabeth Pearson Jan 2003

Driving Without A Map: Father-Son Sexual Health Communication, Alison Elizabeth Pearson

Theses and Dissertations (Comprehensive)

Family sexual health communication is an important area to examine due to the high-risk sexual behaviours that some youth engage in and the influential role that parents can play in teaching and shaping sexual health values. Yet few research studies on family sexual health communication include sons as participants and even fewer include fathers. In this study I attempted to contribute to the literature by examining the perspective of fathers in terms of sexual health communication with their pre-adolescent sons. Eight fathers from Southwestern Ontario with sons between the ages of eight and twelve took part in a qualitative study …

Wheel Running As A Function Of Varying Effort Requirements In Rats, Doreen B. Weise Jan 2003

Wheel Running As A Function Of Varying Effort Requirements In Rats, Doreen B. Weise

Theses and Dissertations (Comprehensive)

These experiments explore a wheel running work-response function with the goal of paralleling the drug magnitude-response (dose-response) function, as a way of measuring the value of running for rats. Friction levels were manipulated by varying the amount of weight applied to running wheels. Experiment 1 examined how male running patterns changed in response to weights applied on alternate days and calculated the work-response scores for each weight. Experiment 2 explored how male running changed when weights were applied for only a portion of the night, on an alternate night schedule. Experiments 3 and 4 replicated the procedures used in Experiments …
