Civil Rights Catch 22s, Jonathan Feingold

Faculty Scholarship

Civil rights advocates have long viewed litigation as a vital path to social change. In many ways, it is. But in key respects that remain underexplored in legal scholarship, even successful litigation can hinder remedial projects. This perverse effect stems from civil rights doctrines that incentivize litigants (or their attorneys) to foreground community plight—such as academic underachievement or overincarceration. Rational plaintiffs, responding in kind, deploy legal narratives that tend to track racial stereotypes and regressive theories of inequality. When this occurs, even successful lawsuits can harden the structural and behavioral forces that produce and perpetuate racial inequality.

Desired Properties Of Recycling-Derived Fertilisers From An End-User Perspective, Aoife Egan, Niamh Power

Grey Literature

The Interreg North-West (NW) Europe ReNu2Farm project aims to increase the recycling rates of the plant nutrients nitrogen (N), phosphorous (P) and potassium (K). Currently, farmers predominantly use mineral fertilisers that are a finite resource and in the case of nitrogen are energy-intensive to produce. Then again, there are several regions in NW Europe with a nutrient surplus and there have been many advances in technology that can recover these nutrients. However, there has been very little up-take overall, with these recycling derived fertilisers (RDFs). To explore the reason behind the reluctance of farmers to use these sustainable recycled products, …

Exploring The Relationship Between Drought And Population Change On The North American Great Plains, 1970-2010, George Heath

Theses and Dissertations (Comprehensive)

Through the second half of the 20th century, the North American Great Plains saw widespread rural out-migration, a continuation of trends that began with the Dust Bowl crisis during the Great Depression of the 1930s. As part of a wider academic focus on the roles climate and environmental changes have on migration, this research project sought to understand the relationship between drought conditions and rural population decline on the Great Plains. In this explorative research, census population data for Canada and the US from 1970-2010 were analyzed along with temperature, precipitation, and Palmer Drought Severity Index data for the same …

Agents At Work: Modeling How Space Can Influence People In The Workplace, Jovan Poposki

Theses and Dissertations (Comprehensive)

People interact with space in ways that are important to consider when designing an office. Not considering this relationship has led to the dissatisfaction of employees post-occupancy. In this thesis, I present an agent-based model that incorporates several characteristics of agents, such as work ethic and sociability, and explores their behaviours and social interactions in the workplace. The model is first tested on a commercial workspace, varying agent parameters to see how they change the behaviour of the model. I find that agents with extreme personalities are happiest, and show a bimodality in the distribution of time spent in various …

Walking In Both Worlds: Learning About Youth Priorities And Indigenous Food Sovereignty With DéLįNę’S Youth Council, Neala Macleod Farley

Theses and Dissertations (Comprehensive)

Indigenous food sovereignty is vital to the protection and restoration of Indigenous food systems and to many Indigenous peoples’ health, culture, and traditions. Working towards Indigenous food sovereignty can also help to enable the protection and continued development of Indigenous knowledge and worldviews, which are becoming increasingly recognized for their potential to help transform unsustainable food systems and combat climate change. In Délįnę, Northwest Territories (NWT), re-establishing intergenerational knowledge transfer to today’s youth is an essential aspect of food sovereignty and the continuation of Dene worldviews. However, this is challenging for many youth as they face conflicting pressures from Western …

Parental Incarceration And Stigma: A Qualitative Content Analysis Of Children's Books, Samantha Nguyen

Theses and Dissertations (Comprehensive)

Children of parental incarceration are often forgotten victims and have been noted to experience collateral consequences such as stigma, poor mental health, and isolation. Since children are often forgotten, there is a lack of information regarding their experiences, what resources are available to them, and whether or not these resources intended to be beneficial. One of the resources that are available to children, caregivers, and other adults are children’s books regarding parental incarceration. To determine whether or not these children's books act as a guide, this study examined the content and illustrations of 19 children’s books on parental incarceration. The …

The Untended Garden: How Adoptees Navigate Relationships With First Family Members, Dawn Michele Mccormick Tracz

Theses and Dissertations (Comprehensive)

This research explores how people who were adopted over the age of 6 years old in open adoption arrangements navigate ongoing relationships with first family members. It explores perceptions of how a connection with both adoptive and first family members impacts self-concept. Using an interpretivist-constructivist lens, the narratives of four women are presented and analyzed. In addition to qualitative interviews, each participant was invited to create images that represented relationships with significant family members. The narratives are re-presented in detail adhering closely to the teller’s organization and emphases. In the analysis, themes related to relationships with first family members and …

Femme Ex Machina: Sex Robots, Embodiment, And Posthuman Subjectivity, Julia A. Empey

Theses and Dissertations (Comprehensive)

Andrea Dworkin warned in her 1974 book Woman Hating that men would soon develop the technology to “create the sex objects that will gratify them” (199). This dissertation investigates one of those technologies: sex robots, as mediated through science fiction film and literature. While the sex robot is still an emerging technology, its embodiment, particularly when female-rendered, has been imagined and negotiated for centuries. Men creating women in a specific, desired image is not new, but the sex robot is currently being transformed from imagined representation to embodied subject. This dissertation traces a pattern of representation that has allowed us …

The Role Of Ovarian Hormones In Appetite-Regulation: Examining The Post-Exercise Appetite Response In Pre- Vs Post-Menopausal Females, Jessica A.L. Tucker

Theses and Dissertations (Comprehensive)

INTRODUCTION: Appetite fluctuates across the menstrual cycle, suggesting ovarian hormones are involved in the regulation of appetite hormones and energy intake. Exercise is another regulator of appetite with higher intensity exercise generating a greater and more consistent suppression. Considering there is limited evidence investigating the role of ovarian hormones in appetite regulation, menopause represents a stage of life where ovarian function declines, thus providing an opportunity to further explore the role of ovarian hormones in the appetite-regulatory response to exercise. PURPOSE: To examine the role of ovarian hormones on appetite-regulating hormones in pre- and post-menopausal females following a …

Fifth-Dimensional Warfare And National Security In Canada: Situating Microdeviation Theory Within C-59: An Act Respecting National Security Matters, Hayden Slight

Theses and Dissertations (Comprehensive)

In an era of rapid technological change, the growing threat environment in the cyber dimension will continue to influence how a sovereign nation contends with attacks that can occur from any corner of the world. The growing adaptation and expansion of technology belonging to the Internet of Things (IoT) and the increasing prevalence of social media (Facebook, Twitter) has also influenced the spreading of attack surfaces that can become victim to exploitation by motivated parties including foreign states and terrorist groups. Against this backdrop, Canada’s own efforts to modernize and reinforce its own national security agencies resulted in the developing …

Relationships Between Executive Functioning, Memory, And Source Judgements On Children’S Responses To Online Advertising, Samantha Barbosa

Theses and Dissertations (Comprehensive)

Children’s understanding of online content is a topic of interest, yet little is known about how children distinguish distracting and often misleading information (e.g., advertisements) from relevant information. Our aim is to measure the relationship between executive functioning, memory and source monitoring in a population that has heavy internet usage and are also the most at risk for mistakenly recalling false or irrelevant information. Children aged 7-12 years old (N = 30), with no known developmental or cognitive disorders, were recruited for the study. In an online session, the children viewed two novel online media sources (i.e., a website …

First Language Loss And Maintenance In Adolescents And Young Adults From Immigrant Backgrounds, Wanxin Li

Theses and Dissertations (Comprehensive)

Abstract

Language attrition is a documented phenomenon that occurs when individuals progressively lose their first language (Schmid et al., 2007). This is particularly common among individuals who relocate to a country that speaks a foreign language that differs from their first language, as the societal language eventually becomes their dominant language. Deterioration and loss of the first language (L1) may result in consequences such as loss of ethnic and cultural identity, leading to the loss of a link to one’s country of origin (Cho & Krashen, 1998). Thus, the present study examined factors that may contribute to L1 attrition. The …

Community Stress And Resilience During Covid-19: Assessing The Emotional Profile Of The City Of Hamilton Using A Social Media Analysis, Senyo Agbeyaka

Theses and Dissertations (Comprehensive)

This study investigated stress and resilience at the neighbourhood level in Hamilton Ontario in pre- and peri-pandemic conditions using a social media analysis. Sentiment analysis of geo-located Twitter posts produced within Hamilton census tract boundaries was conducted using Stresscapes and EMOTIVE, validated software that extract and code emotional information from human language expressions about stress and hope (a proxy for stress), respectively. Baseline levels of both emotions were measured using aggregate scores at the census tract level in Hamilton from tweets produced during two pre-pandemic periods (March 2019 to July 2019; and August 2019 to February 2020), with a replication …

Toxicity Of The Technology Critical Elements Germanium And Yttrium To Daphnia Magna And Hyalella Azteca And The Influence Of Toxicity Modifying Factors, Rashid Shah

Theses and Dissertations (Comprehensive)

Technology critical elements (TCEs) are increasingly used in high and green technologies but there is little aquatic toxicity data for TCEs, particularly in fresh water. The objective of this study was to investigate the toxicity of two TCEs, Ge and Y, to Daphnia magna and Hyalella azteca and to understand the role of natural organic matter and cations on toxicity modification. Testing followed standard methods. The 48 h EC50 for D. magna was 11.6 (95% CI of 9.64-13.8) mg Ge/L based on measured dissolved concentrations at test end. The addition of NOM at 10 mg DOC/L resulted in a significant …

Seasonal Variation And Deposition Of Atmospheric Organophosphate Esters In The Coastal Region Of Shanghai, China, Yuxin Ma, Yuchen Luo, Jincai Zhu, Jinghua Zhang, Guoping Gao, Wenying Mi, Zhiyong Xie, Rainer Lohmann

Graduate School of Oceanography Faculty Publications

The coastal megacity Shanghai is located in the center of the Yangtze River Delta, a dominant flame retardants (FRs) production region in China, especially for organophosphate esters (OPEs). This prompted us to investigate occurrence and seasonal changes of atmospheric OPEs in Shanghai, as well as to evaluate their sources, environmental behavior and fate as a case study for global coastal regions. Atmospheric gas and particle phase OPEs were weekly collected at two coastal sites - the emerging town Lingang New Area (LGNA), and the chemical-industry zone Jinshan Area (JSA) from July 2016–June 2017. Total atmospheric concentrations of the observed OPEs …

Rate Base The Charge Space: The Law Of Utility Ev Infrastructure Investment, Adam D. Orford

Faculty Scholarship

To fight climate change and support the transition to a zero- emissions transportation sector, the United States is setting out to build a huge fleet of electric vehicle (EV) charging stations. But EV charging infrastructure—often called EV supply equipment (EVSE)—is expensive, and how to pay for it is not straightforward. This Article explores the emerging law and policy of using the bill payments of millions of electric utility customers to solve the problem. State utility regulators, in obscure technical proceedings, have begun directing billions of ratepayer dollars toward EVSE. Is this an unfair and risky social spending experiment, as its …

How Do You Meme?: Using Memes For Information Literacy Instruction, Christina Boyle

Publications and Research

Memes, or image macros, have become a standard method of digital information sharing. This is especially true during times when current events ignite a heightened desire for information seeking among students. Memes can be sources of misinformation, such as during events of the past decade, including recent presidential elections, social justice movements such as Black Lives Matter, and the ongoing COVID-19 pandemic. Librarians need to address this format in their information literacy teachings. In this article, the author briefly outlines the rise of internet memes, discusses how higher education students are engaging with them, and highlights some problematic meme-sharing throughout …

What Are The Desired Properties Of Recycling-Derived Fertilisers From An End-User Perspective?, Aoife Egan, Amrita Saju, Ivona Sigurnjak, Erik Meers, Niamh Power

Publications

The circular economy aims to promote the use of recycled products and to close the nutrient cycle loop by avoiding nutrient leakage and detrimental environmental effects, while also reducing the dependency on fossil fuels. The production of nitrogen is energy-intensive, requiring natural gas, whereas, finite resources like phosphorus and potassium are mined. Recent developments in nutrient recovery technologies have resulted in different types of recycling-derived fertilisers (RDFs) with the potential to substitute commonly used synthetic mineral fertilisers. This study aims to understand perceptions and preferences regarding the properties and parameters that end-users find important in RDFs. A better understanding of …

Snake Iconography, Mythology, And The Meaning Of The Bronze Snake Image In Numbers 21:4–9 And 2 Kings 18:4, Mark A. Awabdy

The Asbury Journal

This study pursues the question of why Yhwh, who in the Decalogue prohibits the creation and worship of divine images, would order Moses to create a snake image as the mode of healing snake bites in the desert (Num 21:4–9). This question is legitimated as the Judahites subsequently burn incense to Moses’ bronze snake, which Hezekiah destroys as an act of loyalty to Yhwh. Adopting a definition of meaning from symbolic action theory in cultural psychology, this essay explores what the bronze snake image would have meant for the earliest audiences of these stories. In the core of the essay, …

Biological Sciences Faculty Publications

Marine species and ecosystems are widely affected by anthropogenic stressors, ranging from pollution and fishing to climate change. Comprehensive assessments of how species and ecosystems are impacted by anthropogenic stressors are critical for guiding conservation and management investments. Previous global risk or vulnerability assessments have focused on marine habitats, or on limited taxa or specific regions. However, information about the susceptibility of marine species across a range of taxa to different stressors everywhere is required to predict how marine biodiversity will respond to human pressures. We present a novel framework that uses life-history traits to assess species’ vulnerability to a …

Determinants Of Population Genetic Structure In Chamaecrista Fasciculata (Michx.) Greene (Fabaceae) In The Southeastern United States, Mahboubeh Hosseinalizadeh Nobarinezhad, Lisa E. Wallace

Biological Sciences Faculty Publications

Chamaecrista fasciculata is a widely distributed, phenotypically variable species in the eastern U.S. Whereas studies have demonstrated genetic structure and local adaptation in northern areas of its distribution, there has been no comparison of genetic variability among populations at the southern extent where phenotypic variation is more complex. We characterized genetic variation at 14 microsatellite loci for populations in Mississippi and Alabama and compared this to variation in a phenotypic trait, leaf pubescence. Geographic distance, climatic variables, and elevation were evaluated as factors to explain the observed patterns of genetic diversity. A significant amount of variation (19%) resided among populations, …

Significance Of Autumn And Winter Food Consumption For Reproduction By Southern Beaufort Sea Polar Bears, Ursus Maritimus, Blaine D. Griffen, John P. Whiteman, Sariah Pullan

Biological Sciences Faculty Publications

Polar bears (Ursus maritimus) in the southern Beaufort Sea experience long annual periods when preferred seal prey are scarce or are unavailable. Consumption of bowhead whale (Balaena mysticetus) carcasses from native Alaskan subsistence hunting is increasingly common for onshore polar bears, yet the energetic consequences of this consumption remain unclear. We use data on bears captured repeatedly over periods that encompassed autumn and winter, combined with calculations, to show that adult female bears likely consume an average of at least 4 seal equivalents during both autumn and winter periods and that considerable variation in energy intake …

Streamlining Sporozoite Isolation From Mosquitoes By Leveraging The Dynamics Of Migration To The Salivary Glands, Ashutosh K. Pathak, Justine C. Shiau, Blandine Franke-Fayard, Lisa M. Shollenberger, Donald A. Harn, Dennis E. Kyle, Courtney C. Murdock

Biological Sciences Faculty Publications

Background: Sporozoites isolated from the salivary glands of Plasmodium-infected mosquitoes are a prerequisite for several basic and pre-clinical applications. Although salivary glands are pooled to maximize sporozoite recovery, insufficient yields pose logistical and analytical hurdles; thus, predicting yields prior to isolation would be valuable. Preceding oocyst densities in the midgut is an obvious candidate. However, it is unclear whether current understanding of its relationship with sporozoite densities can be used to maximize yields, or whether it can capture the potential density-dependence in rates of sporozoite invasion of the salivary glands.

Methods: This study presents a retrospective analysis of Anopheles …

Marine protected areas (MPAs), particularly large MPAs, are increasing in number and size around the globe in part to facilitate the conservation of marine megafauna under the assumption that large-scale MPAs better align with vagile life histories; however, this alignment is not well established. Using a global tracking dataset from 36 species across five taxa, chosen to reflect the span of home range size in highly mobile marine megafauna, we show most MPAs are too small to encompass complete home ranges of most species. Based on size alone, 40% of existing MPAs could encompass the home ranges of the smallest …

Patterns Of Interdisciplinary Collaboration Resemble Biogeochemical Relationships In The Mcmurdo Dry Valleys, Antarctica: A Historical Social Network Analysis Of Science, 1907–2016, Stephen M. Chignell, Adrian Howkins, Poppie Gullett, Andrew G. Fountain

Geology Faculty Publications and Presentations

Co-authorship networks can provide key insights into the production of scientific knowledge. This is particularly interesting in Antarctica, where most human activity relates to scientific research. Bibliometric studies of Antarctic science have provided a useful understanding of international and interdisciplinary collaboration, yet most research has focused on broad-scale analyses over recent time periods. Here, we take advantage of a ‘Goldilocks’ opportunity in the McMurdo Dry Valleys, an internationally important region of Antarctica and the largest ice-free region on the continent. The McMurdo Dry Valleys have attracted continuous and diverse scientific activity since 1958. It is a geographically confined region with …

Crispr/Cas9-Mediated Genome Editing Reveals 12 Testis-Enriched Genes Dispensable For Male Fertility In Mice, Yuki Oyama, Haruhiko Miyata, Keisuke Shimada, Yoshitaka Fujihara, Keizo Tokuhiro, Thomas X Garcia, Martin M Matzuk, Masahito Ikawa

Faculty, Staff and Students Publications

Gene expression analyses suggest that more than 1000-2000 genes are expressed predominantly in mouse and human testes. Although functional analyses of hundreds of these genes have been performed, there are still many testis-enriched genes whose functions remain unexplored. Analyzing gene function using knockout (KO) mice is a powerful tool to discern if the gene of interest is essential for sperm formation, function, and male fertility in vivo. In this study, we generated KO mice for 12 testis-enriched genes, 1700057G04Rik, 4921539E11Rik, 4930558C23Rik, Cby2, Ldhal6b, Rasef, Slc25a2, Slc25a41, Smim8, Smim9, Tmem210, and Tomm20l, using the clustered regularly interspaced short palindromic repeats /CRISPR-associated …

Paraventricular Vitamin D Receptors Are Required For Glucose Tolerance In Males But Not Females, Jessie Beck, Silvania Da Silva Teixeira, Keisha Harrison, Gabrielle Phillips, Yanlin He, Stephanie Sisley

Faculty, Staff and Students Publications

When delivered directly into the brain, vitamin D, can improve glucose levels in male mice. Additionally, the loss of the vitamin D receptor (VDR) in male mice's paraventricular hypothalamus (PVH) results in impaired glucose tolerance. Data in humans shows that low vitamin D levels are detrimental to glucose homeostasis, an effect that may be more prominent in men. However, it is unknown if vitamin D action in the brain is required for normal glucose regulation in female mice. This study shows that in both viral and genetic models, male mice with obesity and PVH VDR loss have impaired glucose tolerance …

5g Mobility Management Using Satellites In Leo (Low Earth Orbit), Peter Knight

Master's Projects

As technology moves forward we find ourselves demanding faster and better quality internet. Towards that end, 5G was developed. While cell towers are already being built with 5G in mind, some of the built-in limitations of 5G mean that we may be seeing satellites with it in the near future. This development would require a drastic change in the current algorithms used for handovers. These algorithms fail to take into account the high relative velocity of the satellites and result in many unnecessary handovers which increases the likelihood of a dropped connection. This paper will propose and evaluate the effectiveness …
