Three Essays In Green Product Development: Co-Opetition, Sustainability, And Regulations, Maryam Hafezi

Theses and Dissertations (Comprehensive)

Pollution, global warming, ozone depletion and the greenhouse effect have brought environmental issues to the fore. As a result, consumers, governments and NGOs have pressured firms to develop green products. Green products are those “that strive to protect or enhance the natural environment by conserving energy and/or resources and reducing or eliminating use of toxic agents, pollution, and waste’’. Pressures from those stakeholders are not the only reasons for firms to become involved in green product development. Other reasons include the opportunities for accessing new markets, enhancing competitive advantages, gaining cost efficiency, and building a better reputation.

Using Rainbow Trout Cell Lines As A Model For Understanding The Innate Anti-Fv3 Immune Response, Graeme Robert Jones Lisser

Theses and Dissertations (Comprehensive)

Ranavirus infections are on the rise and have been implicated in numerous species die-offs across the globe. Frog virus 3 (FV3) is the type-species of the genus, yet the immune mechanisms governing susceptibility remain poorly understood. Arguably the most important immune response to infection is the type I interferon (IFN) response. Type I IFNs trigger an “antiviral state” in host cells via the production of numerous interferon-stimulated genes (ISGs) that act to inhibit virus replication in various way, including the induction of apoptosis. Apoptosis is an important antiviral defense mechanism to limit virus replication within infected cells. This study employed …

Dsrna Sensing In Fish Cells: Using Chse-214 As A Model For The Study Of Class A Scavenger Receptors, Andrea Monjo

Theses and Dissertations (Comprehensive)

When infecting cells, most viruses produce dsRNA molecules at some point in their replicative cycle. When an infection results in cell lysis, these molecules are released into the extracellular space. Class A scavenger receptors (SR-As) on the surface of animal cells bind extracellular dsRNA and bring it into the cell where dsRNA triggers an innate immune response, enabling the cell to protect itself from an impending virus infection. Very few cells are unable to bind and respond to extracellular dsRNA, thus cell-based assays for studying extracellular dsRNA sensing via SR-As have been limited. CHSE-214 cells are a promising model for …

Reproductive Characterization Of Walleye (Sander Vitreus) And Lake Whitefish (Coregonus Clupeaformis) In Tathlina Lake, Nt, Grant M. Harrison Mr

Theses and Dissertations (Comprehensive)

Tathlina Lake, NT is an ecologically and culturally important lake to the Ka’a’gee Tu First Nation and supports a small commercial fishery for walleye (Sander vitreus) and a subsistence fishery for lake whitefish (Coregonus clupeaformis). The community is concerned about existing fluctuations in the fish populations. They are also concerned with environmental pressures, including potential future oil and gas development in the near-by Cameron Hills and climate change, and desires to institute long-range biomonitoring in the lake. Male and female adult walleye and lake whitefish, in pre- and post-spawning conditions, were collected biannually in March and …

Immigration, Integration And Ingestion: The Role Of Food And Drink In Transnational Experience For North African Muslim Immigrants In Paris And Montréal, Rachel D. Brown

Theses and Dissertations (Comprehensive)

This dissertation is motivated by two research questions: (1) how can food act as a means of reimagining, recreating, reaffirming, and expressing, sometimes complicated and contested identities for minority religious immigrant communities in highly secular contexts? (2) What impact does the context of reception, particularly the host society’s unique and complex history and interaction with colonialism, immigration, secularism, and nationalism, have on these identity negotiations? To examine these questions, I conducted a comparative ethnographic study of the foodways of North African Muslim immigrants in Paris, France, and Montréal, Canada, in 2012-13.

The results presented here show that food is often …

The Risk Of Risk: An Exploration Of The Impact Of “Risk” On Child Welfare Decision-Making, Jill K. Stoddart

Theses and Dissertations (Comprehensive)

Objective: In this paper, child welfare decision-making is critically assessed in relation to Beck’s (1992) concept of ‘risk society’. Three key decisions made by child welfare workers during the initial investigation are examined in order to illustrate how risk influences the type of investigative approach used, the determinations about child maltreatment, and the services provided to children and families and to link theory with policy and practice.

Methods: The three exploratory studies all utilize secondary data from several cycles of the Ontario Incidence Study, which collects information directly from frontline child protection workers about incidence of reported maltreatment. Two studies …

In Search Of Lost Selves: Memory And Subjectivity In Transnational Art Cinema, Anders J. Bergstrom

Theses and Dissertations (Comprehensive)

This dissertation begins from the position that cinema’s ongoing persistence as a specific operation of subjective perception is intimately related to the questions of self and memory it raises. Even as digitization and global capitalism have ostensibly led to the creation of a “post-cinematic” culture, cinematic forms and practices remain inextricably related to the larger (often unacknowledged) metaphysical concerns of the cultures and social contexts in which they continue to signify. These concerns—which include beliefs in perceptual realism, the relations between images and the past, and notions of selfhood—shape both the production and consumption of cinema as a tool which …

Uncovering The Processes And Consequences Of Egyptian Immigrant Parental Involvement In Their Children’S Education: Bridging Cultural Differences, Hend Shalan

Theses and Dissertations (Comprehensive)

Abstract

For more than a decade, researchers have concluded that immigrant parents face several barriers to becoming involved in their children’s education. All studies agree that language and cultural differences are the most significant barriers to immigrants’ involvement in their children’s education, yet we know little about what these cultural differences are and how these cultural differences influence the school involvement of immigrant parents. This study integrates theories of cultural differences, acculturation, and culture shock and the corresponding literature to investigate the lesser involvement of immigrant parents in school-related activities.

A focused ethnographic design was employed and a thematic analysis …

Size And Shape Control In Metal Nanoparticles And Nanocomposites, Tomendro Subedi

Theses and Dissertations (Comprehensive)

This thesis describes major findings on the shape transformation of the precursor silver decahedral nanoparticles (AgDeNPs) with pentagonal symmetry and twin defects into silver pentagonal prism nanoparticles (AgPPNPs) using Br¯ as a shape selective reagent. Silica-encapsulation of the gold-plated AgDeNPs was also carried out forming ordered arrays of silica encapsulated gold-plated AgDeNPs (SiO₂@Au@AgDeNPs) of different sizes. At first, synthetic procedures for AgDeNPs (pentagonal bipyramids), silver pentagonal rod nanoparticles (AgPRNPs) and gold-plating of AgDeNPs (Au@AgDeNPs) were optimized. Gold plating enhances the chemical stability of AgDeNPs and preserves the superior plasmonic properties of silver. This thesis deals with the transformation …

Exclusion From Rights Through Extra-Territoriality At Home: The Case Of Paris Roissy-Charles De Gaulle Airport's Waiting Zone, Pauline Gj Maillet

Theses and Dissertations (Comprehensive)

In this dissertation I argue that, since the 1980s, French airports have been designed to exclude people from legal, human and refugee rights. The particular space where this happens has been successively called “international zone”, “transit zone” and “waiting zone” and its scope has been significantly extended overtime. I contend that French authorities have used the concept of extra-territoriality in concert with the material design of the airport to sustain exclusion. While this research focuses on France, findings bear relevance to the global governance of migrants and refugees. The French case epitomizes how states creatively use the law (or absence …

Jailhouse Informants In Canadian Criminal Courts, Olena Beshley

Theses and Dissertations (Comprehensive)

Criminal justice systems in Canada and around the world have been established to deal with matters that require attention, punishment, and justice. An important function of criminal justice systems is the evaluation of evidence presented in the court of law. Evidence from jailhouse informants who testify that they have been privy to confessions of crimes is a contentious issue. Much of the scholarly literature available to date on wrongful conviction cases focuses on causes of insufficient and unreliable evidence obtained through different techniques and from different sources. Despite the high number of investigations into wrongful conviction cases, the subject of …

Why Be Moral? Moral Motivation Across Context And Age, Rosemary Victor Abdou

Theses and Dissertations (Comprehensive)

Research on moral identity has not provided evidence for age-related trajectories in moral identity development. There has been a focus on a specific age range, particularly adolescence and emerging adulthood, ignoring older age groups and their development. In addition, research has focused on broad notions of intrinsic versus extrinsic moral motivation, without taking into consideration the various contexts in which moral behavior is expressed. There exists no current research on age differences in moral motivation. This study investigated differences in moral motivation across four consecutive age groups; adolescence (14-18 years, n = 67, 41 females), emerging adulthood (19-25 years, n …

Differences In Frn And P300 Amplitudes Among Hockey Fans Versus Non-Hockey Fans In Response To Relevant And Irrelevant Information., Omar Rafiq

Theses and Dissertations (Comprehensive)

Sports bettors tend to rely on statistical information about an athlete or team’s past performance even though this type of information often has no predictive value. The belief that this statistical information can help predict future performance is typically held by experts and novices alike. A recent study conducted by Cheng and colleagues (in preparation) suggests that sports bettors do not process decision outcomes that are based on relevant information in the same way that they process decision outcomes based on irrelevant information. Specifically, they found differences in the event-related potential component known as Feedback-Related Negativity (FRN), such that FRNs …

Climate And Capitalism: English Perceptions Of Newfoundland's Natural Environment And Economic Value, 1610-1699, Joshua Tavenor

Theses and Dissertations (Comprehensive)

For English merchants, planters and politicians, colonizing Newfoundland required learning the limitations and opportunities afforded by the island’s natural environment. The crucial period for this learning process took place from 1610, the first English effort to colonize the island, to the 1699 passing of the Act to Encourage the Trade to Newfoundland, which defined the cod fishery as the island’s only viable industry. During these eighty-nine years, English enterprises and policies consistently failed to meet the expectations of their backers, and new information challenged accepted ideas about Newfoundland’s climate and natural resources, pressuring the supporters of those decisions to …

Based On Actual Events: Surveillance, Fear And Crime Control In Found-Footage Horror Films, Cassandra Persaud

Theses and Dissertations (Comprehensive)

In recent years, found-footage horror films have reappeared with increasing popularity, leading to its recognition as the current horror subgenre du jour. Its amateur style of filmmaking has allowed the subgenre to explore public concerns around the growth of technology, the use of surveillance, and crime control. Found-footage horror films offer a unique platform for analysis as they are framed around presenting the ‘footage’ in the film as factual or reality. In this research study, themes and narratives around the use of surveillance and the production of the docile body in found-footage horror films were examined. The study involved an …

Health-Related Quality Of Life And Physical Activity In University Employees, Meghan Hoefs

Theses and Dissertations (Comprehensive)

Background: Health-related quality of life (HRQL) reflects an individual’s subjective perception. The relationship between health-related quality of life and physical activity has been investigated in various populations, but is not well-documented in University employees. Additionally, variables such as an individual’s beliefs about physical activity and their satisfaction with functioning at work have yet to be investigated in this population. Little is known about the relationship between HRQL and these variables. Purpose: Evaluate the relationships among multiple measures of HRQL and physical activity in University employees and provide a descriptive picture of the University population. Methods: Participants (N …

Impact Of Linear Disturbances On A Discontinuous Permafrost Peatland Environment, Michael Braverman

Theses and Dissertations (Comprehensive)

Permafrost is ground that remains at or below 0°C for at least two consecutive years (PIWP, 2012). In the continuous permafrost zone its thickness may exceed 300 m, in lower latitudes, permafrost thickness is progressively decreasing, its occurrence becomes discontinuous and eventually sporadic (PIWP, 2012). At the southern fringe of permafrost in northwestern Canada, just about few meters. In subarctic peatlands permafrost is one of the main elements governing the hydrological processes. Being very thin and with temperature just fractions of the degree below 0^oC, it is very vulnerable to any changes in soil temperature and water content. …

Narrative Pleasures And Feminist Politics: Popular Women’S Historical Fiction, 1990-2015, Victoria Kennedy

Theses and Dissertations (Comprehensive)

This dissertation contributes to a developing body of work on women’s historical fiction and its significance to feminist discourse. Building from Diana Wallace’s 2005 study The Woman’s Historical Novel: British Women Writers, 1900-2000, I offer a modified definition of “the woman’s historical novel” and a transatlantic consideration of several of the most popular titles in the contemporary period, including The Other Boleyn Girl (2001), Outlander (1991), A Great and Terrible Beauty (2003), and Scarlett (1991). Several studies have followed Wallace’s, notably Ann Heilmann and Mark Llewellyn’s Metafiction and Metahistory in Contemporary Women’s Writing (2007) and Katherine Cooper and Emma …

Accountability, Conservation And Community: Measuring The Local Economic Impacts Of Protected Areas, Catharine A.M. Brazeau

Theses and Dissertations (Comprehensive)

As a signatory to the Convention on Biological Diversity, Canada has committed to help protect biodiversity through an increase in effectively and equitably managed systems of protected areas (PAs) by 2020. If Canada fulfills this commitment, the country will see the largest expansion of PA networks in its history. Although employing ‘equitable and effective management’ suggests PAs have a responsibility to consider their effects on local stakeholders, on the whole, Canada’s PA agencies do not publicly and systematically report on their jurisdictions’ local economic impacts. To address this gap, this thesis aims investigate mechanisms for PA agencies to identify and …

Two Essays On Marketing Capabilities, Hamed Mehrabi

Theses and Dissertations (Comprehensive)

A critical decision for any firm involves allocating investment to different types of marketing activities. One argument is that firms should invest resources in both explorative and exploitative activities to develop ambidexterity. Considering the extensive theoretical and practical implications of ambidexterity, several research gaps exist in this area provide opportunities for both theoretical and practical contributions. In this dissertation, I identify and explore three important research opportunities.

First, based on one argument regarding ambidexterity, firms should pursue exploration and exploitation in a balanced manner. This is even though there is little evidence confirming that being ‘out of balance’ actually hurts …

Appreciation And Respect: Understanding The Decision To Join The Caf After Black Bear Program Using Four Directions And Mixed Methods, Anna Harpe

Theses and Dissertations (Comprehensive)

The purpose of this study is to better understand the wholistic meaning that the Canadian Armed Forces embody for graduates of Black Bear Aboriginal Summer Training Program and the factors involved in the graduates’ decision to join the CAF after graduating Black Bear. This was done using an Indigenous Four Directions framework supported by a mixed methods cross-sectional online survey. Out of respect for the cultures involved, Elders and Cultural Advisors were consulted throughout all stages of the process. The findings suggest that perceptions formed within the Spiritual Direction are important indicators of CAF membership. Wholistically, the CAF maintains a …

Three Essays On Liquidity In Modern Markets, Konstantin Sokolov

Theses and Dissertations (Comprehensive)

Recent technological advancements have challenged financial markets. Academic researchers, regulators and market participants voice concerns that modern markets bear the negative externalities of such advancements. Specifically, they are concerned that today’s markets are becoming more fragile and unfair to less sophisticated traders. This work employs empirical methodology to test whether these concerns are justified. This thesis contains three essays:

The first essay studies whether modern markets become less liquid during intraday extreme price movements (EPMs). When a price moves in a certain direction, liquidity providers face two opposing incentives. The first incentive is to stay in the market to accumulate …

A Comprehensive Study Of Personal And Social Information Use In Female Brown-Headed Cowbirds, Molothrus Ater, Hayden Davies, David J. White

Theses and Dissertations (Comprehensive)

Brood parasites face considerable cognitive challenges when locating and selecting host nests for their young. One aspect of this challenge is determining how to use different sources of information to make decisions regarding the quality of a prospective nest. Here we investigate how female-brown-headed cowbirds, Molothrus ater, use information when prospecting for nests, and then expand upon this to investigate decisions related to foraging. In chapter 1, we demonstrated female could use social information acquired from observing the nest prospecting patterns of conspecifics to influence their own patterns of nest selection. Furthermore, we found a negative relationship between a …

First Nations And Adaptive Water Governance In Southern Ontario, Canada, Thomas Dyck

Theses and Dissertations (Comprehensive)

Water quality and quantity are prominent concerns for First Nations across Canada. The federal government shares the responsibility with First Nations to ensure water resources on-reserves meet the needs of First Nations. Federal approaches have been predominantly technical, focused on addressing issues related to infrastructure, maintenance, training, and monitoring. This approach is important. However, water issues concerning First Nations go beyond technical issues and relate to inadequate participation in decision making, poorly defined roles and responsibilities, and approaches to managing water resources on-reserve that have not accounted for local context. These issues parallel historical nation-to-nation (i.e., First Nations and federal …

"Going The Distance So Our Food Doesn't Have To": Case Studies Of Creative Public Procurement At Canadian And Uk Universities, Lori Stahlbrand

Theses and Dissertations (Comprehensive)

This dissertation explores three efforts to develop sustainable local food systems at public universities in Canada and the UK. One is a partnership between the Canadian non-profit, Local Food Plus (LFP), and the University of Toronto (U of T). The other two are partnerships between the UK non-profit, the Soil Association (SA), and two British universities – Nottingham Trent University (NTU) and the University of the Arts London (UAL). In all three cases studies, a formal certification program to support the transition to more sustainable local food systems was a central feature. The author of this dissertation was the founder …

This dissertation examines the development and implementation of federally funded scientific defence research in Canada during the earliest decades of the Cold War. With a particular focus on the creation and subsequent activities of the Defence Research Board (DRB), Canada’s first peacetime military science organization, the history covered here crosses political, social, and environmental themes pertinent to a detailed analysis of defence-related government activity in the Canadian North. Three contextual chapters on the history of federal defence research in Canada provide the foundation for a close study of defence research projects pursued and supported by the Canadian government. The dissertation …

Young Children's Source Monitoring: Exploring The Contexts Of Task Difficulty And Repeated Events, Becky Earhart

Theses and Dissertations (Comprehensive)

This dissertation had two over-arching goals. The first was to study the cognitive mechanisms underlying effective source monitoring by clarifying the role that developing executive function skills play in children’s increasing ability to monitor sources. The second goal was to examine whether a particular interview technique called “source-monitoring training” could help children to recall the sources of their memories more accurately. These two separate lines of research were furthered by the same methodology, and thus, these separate research questions were examined simultaneously within both of the experiments conducted for this dissertation.

In the first study, the difficulty of the source-monitoring …

Auditory Erp Differences Across A Continuum Of Psychotic Symptoms In Non-Clinical Population, Anaya Rehman

Theses and Dissertations (Comprehensive)

Psychosis is a term given to a mental state described as a loss of contact with the real world. The aim of this thesis was to examine early non-specific psychotic experiences in a healthy population by means of two self-report screening tools: Prime Screen and Youth Psychosis At-Risk Questionnaire-Brief, and place individuals on a psychosis continuum. Across this psychosis continuum, three event related potential (ERP) components were assessed: P300, Mismatch Negativity and N100. There is evidence that P300 and mismatch negativity amplitudes diminish in individuals with psychosis. Similarly, impaired N100 amplitude suppression (increased N100 amplitudes) during vocalization has been observed …

Infants, Toddlers And Mobile Technology: Examining Parental Choices And The Impact Of Early Technology Introduction On Cognitive And Motor Development, Karin Archer

Theses and Dissertations (Comprehensive)

Despite recommendations of no screen time for children under the age of 2, parents are introducing mobile technology to their children at very young ages (Rideout, 2013). While research on television use has found negative impacts in all areas of development (Barr, Lauricella, Zack & Clavert, 2010), research has yet to investigate the impact of mobile technology use with very young children. The current set of 3 studies included interviews, a survey, and direct observations of parents using mobile technology with children 1 to 2 years of age. The main finding across all studies was that parents introduce mobile technology …

The Ripple Effect: Youth Leadership Development And Influence On Environmental Engagement In The Community, Laine Bourassa

Theses and Dissertations (Comprehensive)

Youth leadership is a critical factor in creating momentum for a cultural shift in sustainability practices and can be fostered through youth leadership programs. While evidence exists showing youth environmental programs are able to promote program participant leadership, it is not yet known to what degree these participants are able to improve the environmental engagement of members of their social networks. This “ripple effect” is assessed in the current study through the context of the Make-A-Difference (MAD) Youth Sustainability Leadership Program in New Zealand. The program involves a 3-day social gathering (hui) and ongoing support for several following years. The …
