Benefits, challenges, and limitations of fair trade as a social justice movement

This thesis answers some important questions about how Fair Trade is experienced and perceived by some Northern sellers, consumers, activists, advocates, practitioners, and an importer. As it relates to sellers, I focus only on small scale independent businesses (i.e. I do not include large corporate businesses in my interview sample). Fair Trade works to establish a dignified livelihood for many producers in the South. Some of the most important actors in the Fair Trade movement are the people who buy, sell, and/or advocate for Fair Trade in the North. Fair Trade is largely a consumer movement which relies on the purchase of Fair Trade products. Without consumers purchasing Fair Trade products, retailers providing the products for sale, and activists raising awareness of Fair Trade, the movement, as it is presently constituted, would be non-existent. This qualitative research is based on 19 in-depth i.nterviews with nine interviewees involved with Fair Trade in Canada. I focus on benefits, challenges, and limitations of Fair Trade in the context of their involvement with it. I describe and analyze how people become involved with Fair Trade, what motivates them to do so, what they hope to achieve, and the benefits of being involved. I also describe and analyze how people understand and deal with any challenges and limitations associated with their involvement with Fair Trade. I also explore whether involvement with Fair Trade influences how people think about other products that they purchase and, if so, in what ways. I focus mainly on the commodity of coffee, but my discussion is not limited to this single commodity. Interviewees' experiences with and participation in Fair Trade vary in terms of their level of involvement and interest in the broader Fair Trade movement (as opposed to just participating in the market component). This research reveals that while Fair Trade is a small movement, sellers, consumers, and activists have had much success in the advancement of Fair Trade. While challenges have not deterred interviewees from continuing to participate in Fair Trade, analysis and explanation of such challenges provides the opportunity for Fair Trade practitioners to develop effective solutions in an effort to meet the needs of various Fair Trade actors.

Profitable opportunities around macroeconomic announcements in the U.S. Treasury market

This thesis studies the impact of macroeconomic announcements on the U.S. Treasury market and investigates profitable opportunities around macroeconomic announcements using data from the eSpeed electronic trading platform. We investigate how macroeconomic announcements affect the return predictability of trade imbalance for the 2-year, 5-year, IO-year U.S. Treasury notes and 30-year U.S. Treasury bonds. The goal of this thesis is to develop a methodology to identify informed trades and estimate the trade imbalance based on informed trades. We use the daily order book slope as a proxy for dispersion of beliefs among investors. Regression results in this thesis indicate that, on announcement days with a high dispersion of beliefs, daily trade imbalance estimated by informed trades significantly predicts returns on the following day. In addition, we develop a trade-imbalance based trading strategy conditional on dispersion of beliefs, informed trades, and announcement days. The trading strategy yields significantly positive net returns for the 2-year T-notes.

The effects of a 12-week multifactorial exercise and balance training program on balance control in older adults

The current thesis investigated the effects of a 12-week multifactorial exercise and balance training program on balance control in older adults. Participants completed a baseline testing session which included a series of questionnaires, anthropometric measures, and 18 stance and walking tests. Those who were randomly assigned to the exercise group participated in the 12-week training program while the comparison group was asked not to change anything in his/her lifestyle during the 12-week control period, but were invited to participate in the training program after his/her control period. The same testing protocol was repeated after the 12-week period. The results indicated that there were improvements in the time to complete the walking tests but no change in trunk sway in both the exercise and comparison groups. No changes in stance durations or trunk sway were observed. The findings suggest that the current training program showed no significant improvement in balance control in healthy older adults.

The effect of a segmental, localized lower limb cooling protocol on muscular strength and balance

The human neuromuscular system is susceptible to changes within the thermal environment. Cold extrinsic temperatures can significantly reduce muscle and nervous system function and communication, which can have consequences for motor performance. A repeated measures design protocol exposed participants to a 12°C cold water immersion (CWI) up to the ankle, knee, and hip to determine the effect that reduced skin and muscle temperature had on balance and strength task execution. Although a linear reduction in the ability to perform balance tasks was seen from the control condition through to the hip CWI, results from the study indicated a significant reduction in dynamic balance (Star Excursion Balance Test reach distance) performance from only the hip CWI (P<0.05). This reduced performance could have been due to an increase in joint stiffness, increased agonist-antagonist co-contraction, and/or reduced isokinetic muscular strength. Reduced physical performance due to cold temperature could negatively impact outdoor recreational athletics.

The Political Economy of St. Catharines' Illicit Taxi Trade

The global restructuring of production has led to increasingly precarious working conditions around the world. Post-industrial work is characterized by poor working conditions, low wages, a lack of social protection and political representation and little job security. Unregulated forms of work that are defined as “irregular” or “illegal”, or in some cases “criminal,” are connected to sweeping transformations within the broader regulated (formal) economy. The connection between the formal and informal sectors can more accurately be described as co-optation and, as a subordinate integration of the informal to the formal. The city of St. Catharines within Niagara, along with much of Ontario’s industrial heartland, has been hard hit by deindustrialization. The rise of this illegal service is thus viewed against the backdrop of heavy economic restructuring, as opportunities for work in the manufacturing sector have become sparse. In addition, this research also explores the paradoxical co-optation of the growing illicit taxi economy and consequences for racialized and foreign credentialed labour in the taxi industry. The overall objective of this research is to explore the illicit cab industry as not only inseparable from the formal economy, but dialectically, how it is as an integrated and productive element of the public and private transportation industry. Furthermore the research examines what this co-optation means in the context of a labour market that is split by race.

Hyperosmotic Stress and the Impact on Metabolite Formation and Redox Balance in Saccharomyces cerevisiae and Saccharomyces bayanus strains

Wine produced using an appassimento-type process represents a new and exciting innovation for the Ontario wine industry. This process involves drying grapes that have already been picked from the vine, which increases the sugar content due to dehydration and induces a variety of changes both within and on the surface of the grapes. Increasing sugar contents in musts subject wine yeast to conditions of high osmolarity during alcoholic fermentations. Under these conditions, yeast growth can be inhibited, target alcohol levels may not be attained and metabolic by-products of the hyperosmotic stress response, including glycerol and acetic acid, may impact wine composition. The further metabolism of acetic acid to acetylCoA by yeast facilitates the synthesis of ethyl acetate, a volatile compound that can also impact wine quality if present in sufficiently high concentrations. The first objective of this project was to understand the effect of yeast strain and sugar concentration on fermentation kinetics and metabolite formation, notably acetic acid and ethyl acetate, during fermentation in appassimento-type must. Our working hypotheses were that (1) the natural isolate Saccharomyces bayanus would produce less acetic acid and ethyl acetate compared to Saccharomyces cerevisiae strain EC-1118 fermenting the high and low sugar juices; (2) the wine produced using the appassimento process would contain higher levels of acetic acid and lower levels of ethyl acetate compared to table wine; (3) and the strains would be similar in the kinetic behavior of their fermentation performances in the high sugar must. This study determined that the S. bayanus strain produced significantly less acetic acid and ethyl acetate in the appassimento wine and table wine fermentations. Differences in acetic acid and ethyl acetate production were also observed within strains fermenting the two sugar conditions. Acetic acid production was higher in table wine fermented by S. bayanus as no acetic acid was produced in appassimento-style wine, and 1.4-times higher in appassimento wine fermented by EC-1118 over that found in table wine. Ethyl acetate production was 27.6-times higher in table wine fermented by S. bayanus, and 5.2-times higher by EC-1118, compared to that in appassimento wine. Sugar utilization and ethanol production were comparable between strains as no significant differences were determined. The second objective of this project was to bring a method in-house for measuring the concentration of pyridine nucleotides, NAD+, NADP+, NADH and NADPH, in yeast cytosolic extract. Development of this method is of applicative interest for our lab group as it will enable the redox balance of the NAD+/ NADH and NADP+/ NADPH systems to be assessed during high sugar fermentations to determine their respective roles as metabolic triggers for acetic acid production. Two methods were evaluated in this study including a UV-endpoint method using a set of enzymatic assay protocols outlined in Bergmeyer (1974) and a colorimetric enzyme cycling method developed by Sigma-Aldrich® using commercial kits. The former was determined to be limited by its low sensitivity following application to yeast extract and subsequent coenzyme analyses, while the latter was shown to exhibit greater sensitivity. The results obtained from the kits indicated high linearity, accuracy and precision of the analytical method for measuring NADH and NADPH, and that it was sensitive enough to measure the low coenzyme concentrations present in yeast extract samples. NADtotal and NADPtotal concentrations were determined to be above the lower limit of quantification and within the range of the respective calibration curves, making this method suitable for our research purposes.

A Masters Student’s Journey: Trying to Balance Two Eyes of Research

This project is about a reflective research journey taken by a Masters student in the Child and Youth Studies Department at Brock University in St. Catharines Ontario. This journey consisted of a mixed method approach using the qualitative method of autoethnography along with the Indigenous research method of storytelling. The research was done using the concept of two-eyed seeing which consisted of trying to balance the two eyes of research: Indigenous and Western. The Non-Aboriginal researcher not only reflected on her own learning journey but also the lessons she learned from the voices of 48 women from Six Nations of the Grand River Territory. Like the trickster character Coyote, the researcher struggled, stumbled and was transformed by this journey.

Can Attention Focus Instructions Reduce the Effects of Fatigue on Balance Control?

Localized muscular fatigue has been identified to have detrimental effects on balance control, an important skill for everyday life. Manipulation of attention focus instructions has been shown to benefit performance of various motor skills including balance and has been found to facilitate endurance during fatiguing tasks. The purpose of this thesis was to determine if the use of attention focus instructions could attenuate the effects of muscular fatigue on balance control. Twenty-four participants performed a balance task (two-legged stance on an unstable platform) before and after a fatigue protocol. Trunk sway, platform excursions, and lower limb muscle activity was measured. Results suggest that use of either internal or external attention focus instructions can reduce the immediate effects of muscular fatigue of the lower limb on balance control as shown through reduced trunk sway and platform excursions. These results have relevance for individuals performing balance tasks in a fatigued state.

The Influence of Burnout Symptoms on the Relationship between Work-Life Balance and Self-Rated Health

The effects of stress at work are estimated to cost Canadian employers more than 20 billion dollars annually through absenteeism, sick leave and decreased productivity. Over the past two decades, Canadians have reported higher stress levels, increased work hours and more work performed outside of normal business hours. This work-life imbalance has far-reaching repercussions–affecting an employee’s performance as well as their health. Chronic exposure to these high levels of stress can also lead to burnout. The primary purpose of this study was to determine the magnitude in which burnout symptoms influence the relationship between work-life balance and self-rated health. The secondary purpose of this study was to determine if gender and age interactions exist in the relationship between burnout, work-life balance, and self-rated health. This cross-sectional study involved secondary analysis of 220 managers, workers and human service professionals who completed an Occupational Health Clinics for Ontario Workers’ Mental Injury Toolkit (MIT) survey for the launch of the MIT. The MIT survey is a modified form of the short version of the Copenhagen Psychosocial Questionnaire and includes expanded questioning around burnout, stress, sleep troubles, cognitive, and somatic symptoms. There were no significant differences in self-rated health based on a respondent’s gender or age, indicating that no interaction of gender and age would be required. Respondents with low self-rated health reported significantly higher burnout and work-life imbalance compared to those with high self-rated health. The regression analysis demonstrated that the magnitude in which burnout mediates the relationship between work-life balance and self-rated health was 96%. These findings support previous studies that associate high levels of work-life imbalance or burnout with poor self-rated health or health outcomes. In this study, the shared variance between work-life balance and burnout also supports recent efforts to redefine the context and causes of burnout to include non-work factors. Based on our findings, the potential exists for the development of workplace health promotion strategies that address maintaining a balance between work and home as they may improve employee health and reduce burnout.
