A literature review was conducted alongside a global survey of 40 museum professionals to assess how freezing protocols are implemented, what materials are considered safe, and what challenges arise in real world applications. Results show that while freezing remains a widely …

The Use Of Ai In Canadian Courts, Shaughnessy Dow

Dalhousie Journal of Legal Studies

Like many other fields, there has been growing discussion about the potential benefits of AI for the law. In light of the Federal Court’s interim principles and guidelines on the use of AI, this paper considers whether AI applications can assist the judiciary with its decision-making function. In doing so, it starts by considering the role that judges play in our legal system, finding that they are often called upon to consider and weigh information with human, emotional qualities and to assess the broader policy implications of their legal rulings. This paper concludes that the optimism of proponents of AI …

A Framework For Interpreting Emojis In Legal Contexts, Anne Merritt

Dalhousie Journal of Legal Studies

In the 2023 case of South West Terminal Ltd. v. Achter Land & Cattle Ltd., a Saskatchewan court found that a thumbs-up emoji, as a standalone item of communication, constituted the acceptance of a contract between a buyer and seller. The trial judge noted that such communication was “the new reality in Canadian society” for which courts should be prepared to interpret novel units of language arising in the digital age. However, an analysis of recent Canadian cases involving emojis shows that courts have not been prepared, with inconsistencies in how emojis are represented in evidence, how they are …

The Reverse Onus At Bail For Intimate Partner Violence: An Unconstitutional And Ineffective Measure, Ella Peterson

Dalhousie Journal of Legal Studies

The recently adopted reverse onus at bail for repeat intimate partner violence is a piece of performative legislation that is ineffectual and may harm those it seeks to protect. Part I of this paper provides an overview of intimate partner violence in Canada in order to contextualize s. 515(6)(b.1) of the Criminal Code. Part II is a Charter assessment of the reverse onus provision at issue, focusing on sections 7 and 11(e). Part III concludes with a critique of the effectiveness of the reverse onus, which fails to address the root causes of intimate partner violence.

Canada's Foreign Fighter Problem: How Should The Federal Government Manage Suspected Isis Members Held In Syria?, Mira Stephenson

Dalhousie Journal of Legal Studies

Since the Islamic State of Iraq and Syria (ISIS) fell in 2019, the Autonomous Administration of North and East Syria (AANES) has arbitrarily detained tens of thousands of accused ISIS fighters and their families in Northern Syria. Among those detained are Canadian citizens. Although Canada has repatriated Canadian women and children from AANES custody, its policy approach to date has been inadequate.

Canada must take action to develop a cohesive policy for the approximately 17 Canadians remaining in AANES custody. In this paper, I will evaluate four potential policy options available to the Canadian government. First, that Canada could take …

Meaning In Occupational Therapy Practice: A Mixed Methods Study Exploring Perceived Meaning And Burnout In Occupational Therapists, Rebecca Lauren Reinhardt

Dissertations

Decreasing burnout and increasing retention of occupational therapists (OTs) is a pressing issue in the field as attrition rates and intention to leave the profession are on the rise. One of the core tenets of occupational therapy (OT) practice is supporting recipients with engaging in meaningful occupations to promote wellbeing. While burnout in the profession has been more widely researched, very little research has explored how OTs perceive meaning in their own practice. The purpose of this mixed methods study was to explore the lived experiences of how OTs perceive meaning and meaning gaps in the profession, as well as …

Emerging Adulthood, Identity Conflict, And Self-Compassion’S Impact On Mental Health Interference Of Collegiate Student-Athletes, Courtney Amber Shields

Dissertations

Prior research identified a strong connection between experiences of being a collegiate student-athlete with mental health-related struggles; however, little research has been conducted into how the competing identities of student and athlete within a heavy identity developmental period (emerging adulthood) might be impacting mental-health interference. The purpose of this quantitative study was to understand how emerging adulthood, student identity, athletic identity, and the conflicting role of student-athlete identity had in mental health interference on training, competition, and willingness to see a sports psychologist within collegiate student-athletes as well as how self-compassion moderated these relationships. The following research questions guided this …

Reinforcement Learning And Virtual Human Animation: A Novel Approach To Data-Driven Animation, Portraying Dynamic, Flexible Human-Like Behaviours, Vihanga Gamage

Dissertations

Virtual characters require animation capable of portraying dynamic, context-sensitive human-like behaviours. Several approaches to generating such animation have been developed, but each carries limitations. Motion capture can produce high-fidelity animation but is expensive and ill-suited to systems that must respond in real time. Physics-based reinforcement learning (RL) enables flexible, dynamic behaviour portrayal, yet relies on simulation feedback signals that are unavailable for social gestures. Supervised approaches can learn social behaviours from motion capture data but yield agents with limited flexibility and generalisation.

This thesis presents RLAnimate, a model-based, data-driven RL framework for character animation that enables a single agent to …

Synthesis Of Novel Derivatives From Machilin C/D As Antiproliferative Agents Against Triple Negative Breast Cancer, Alyson M. Ackerman, Chibuzor Olewele, Bert C. Lynn, Samuel G. Awuah

Chemistry Faculty Publications

Lignans are small polyphenolic compounds that play an active role in plant defense against pathogens and predators. Recently, lignan machilin D was reported to be effective as an anti-tumorigenic agent in triple negative breast cancer (TNBC) tumor-bearing mice. Previous studies have relied on plant-extracted material limiting scalability and diversification of the natural scaffold. Herein, we describe a generalizable one-pot synthesis of machilin D and its derivatives via an iron chloride-induced dimerization of isoeugenol. Employing this synthetic methodology allowed for a robust diversification campaign to access seven (7) new lignan derivatives of the machilin D family with superior anti-proliferative properties in …

The Role Of The Jnk Gene In Ovarian Cancer Inflammatory Pathways, Tashoy D. Campbell

Graduate Student Dissertations, Theses, Capstones, and Portfolios

Ovarian cancer, one of the leading causes of cancer-related deaths in women globally, presents a significant challenge due to its common late-stage diagnosis and chemoresistance (inability of the tumor to respond to drugs). The c-Jun N-terminal kinase (JNK) signaling pathway plays a crucial role in ovarian cancer progression, contributing to inflammation, tumor survival, metastasis, and chemotherapy resistance. This literature review examines the role of the JNK signaling pathway in ovarian cancer, with a focus on its role in inflammation, metastasis, and chemoresistance. JNK regulates key inflammatory cytokines, such as TNF-α and IL-6, which promote tumor growth and immune evasion. Moreover, …

Autoregressive Temporal Modeling For Advanced Tracking-By-Diffusion, Pha Nguyen, Rishi Madhok, Bhiksha Raj, Khoa Luu

Electrical Engineering and Computer Science Faculty Publications and Presentations

Object tracking is a widely studied computer vision task with video and instance analysis applications. While paradigms such as tracking-by-regression,-detection,-attention have advanced the field, generative modeling offers new potential. Although some studies explore the generative process in instance-based understanding tasks, they rely on prediction refinement in the coordinate space rather than the visual domain. Instead, this paper presents Tracking-by-Diffusion, a novel paradigm for object tracking in video, leveraging visual generative models via the perspective of autoregressive models. This paradigm demonstrates broad applicability across point, box, and mask modalities while uniquely enabling textual guidance. We present DIFTracker, a framework that utilizes …

A Qualitative Interpretative Meta-Analysis Of The Experiences Of Women Under Community Supervision, Gifty Kinful

Research Papers

Research reveals that women parolees or probationers encounter both challenges and support systems as they navigate their reintegration into the community. More specifically, most women returning from prison and those on probation are released into a society of stigma where access to housing, employment, education, transportation, and healthcare services is either severely limited or nonexistent. These serious obstacles can undermine their ability, motivation, and desire to succeed while on probation or parole. Support systems may be more or less available and effective. The qualitative literature on women under community supervision is large but to our knowledge, the diverse studies have …

Even In Death, Divided By Law: The Permanent Injustice Of Cemetery Segregation In Southern Illinois And The Legacy Of Isaac Burns, Local Civil War Veteran, Taylor Phillips

Southern Illinois University Law Journal

In death, are we truly equal? A Cemetery in Pinckneyville, Illinois, bears silent witness to a relentless history that preserves a racial divide thought to be buried away. Hidden in the segregated section lies Isaac Burns, an African American Civil War veteran, separated from those buried with honor. His grave lies alongside those of other African Americans buried in an area marked not by the unity of service but by the nation's refusal to see them as equals. Burn's grave is a reminder that the legacy of his sacrifice, once given in the name of unity and freedom, is overshadowed …

Advanced Interactions Of Directed Energy With Retinal Pigment Epithelial Cells And Their Photochemical And Photothermal Responses, Jin B. Ha

Theses & Dissertations

Excess optical radiation can injure the retina through either rapid heat deposition (photothermal damage) or cumulative photo‑oxidative stress (photochemical damage), yet current laser‑safety limits treat these mechanisms as independent. To test that assumption, this dissertation integrated systematic wavelength, duration and temperature‑controlled laser exposures with live/dead fluorescence imaging in a melanin‑loaded hTERT‑RPE1 monolayer model. First, concurrent 447 nm (blue) and 2 µm (infra‑red) beams delivered for 200 s demonstrated a strong thermal–photochemical synergy: each beam alone was sub‑threshold (≤25 % lethality) but together produced 100 % RPE death without exceeding 50 °C, proving that modest heating markedly lowers the photon dose …

Novel Sequential Modeling Framework Improves Phytoplankton Biomass Predictions In Response To Multiple Environmental Stressors, Zhuyin Tong, Jiayu Guo, Yikai Liu, Lizhen Lin, Jixin Chen, Xin Liu, Bangqin Huang, Edward A. Laws, Wupeng Xiao

Faculty Publications

Understanding the impacts of multiple environmental stressors on phytoplankton biomass is crucial for predicting marine ecosystem responses under global climate change. This study employed a sequential modeling framework integrating principal component analysis, generalized additive models, and artificial neural networks to improve predictions of phytoplankton chlorophyll a concentrations in the Taiwan Strait. Analyzing a decadal dataset, we found that a 2°C rise in sea surface temperature and a 0.2 pH decline will each lead to an 11.3% reduction in chlorophyll a biomass, whereas nitrogen enrichment is expected to increase it by only 2.8%. The combined effects of these stressors will result …

Cell Death Helps To Stabilize Populations Of Prochlorococcus, P. Wang, E. A. Laws, C. Liang, X. Liu, J. Chen, Y. Zhong, C. Li, B. Huang

Faculty Publications

Prochlorococcus is one of the dominant phytoplankton species in tropical and subtropical pelagic marine ecosystems. To maintain its population equilibrium in oligotrophic waters, the dominant species Prochlorococcus requires high loss rates to offset its high abundance and growth rates. While theoretical frameworks recognize multiple loss processes for Prochlorococcus (viral lysis, environmental stress, programmed cell death), prevailing population studies attribute main mortality to grazing. This oversight stems from in situ data gaps of non-grazing mortality processes. In this study, we firstly formulated simple differential equations that took account of population losses due to both grazing and cell death. We then used …

In The Name Of The Mother, The Nation, And The Race: White Women, The Jim Crow South, & Moralized White Supremacist Feminism, Shayna M. Lawson

Theses and Dissertations

This thesis introduces the concept of moralized white supremacist feminism to examine the central role white women played in constructing, legitimizing, and sustaining racial hierarchies in the Jim Crow South through a network of cultural and political organizing, particularly through the United Daughters of the Confederacy and Women’s Ku Klux Klan. Far from passive observers, white women were strategic agents of segregation, leveraging ideals of purity, motherhood, and moral virtue to enforce anti-Black violence and oppression through educational, civic, legal, and symbolic institutions, as well as extra-legal practices. Drawing from archival materials, oral histories, and critical race theory, this study …

Intergenerational Transmission Of Health: Evidence From Indonesia, Fatima Khan

Theses and Dissertations

This study estimates the causal transmission of health from mothers to their children. Intergenerational associations in health and other human capital outcomes are well established, but those associations may not be causal due to common unobserved factors between a mother and her child. This study employs two-stage least squares, using weather variation as an instrument, to causally identify the relationship between maternal health and child health outcomes in five dimensions: height-for-age, self-reported health, blood pressure, lung capacity, and hemoglobin levels. The data are from the Indonesian Family Life Survey (1993--2014), a longitudinal survey that provides a 21-year look into the …

A Quiet Privilege: Garrity, Internal Investigations, And The Need For A Preference Of Silence Among Public Employees, Jacob Abel

University of Florida Journal of Law & Public Policy

When a public employee is asked to testify against themselves or face termination, they are presented with a trilemma. They may choose to respond to questions falsely, answer truthfully, and suffer criminal sanctions, or remain silent and lose their job. In Garrity v. New Jersey, the Supreme Court resolved this trilemma by ruling that, when a public employee is compelled to answer questions, the Fifth Amendment grants the employee immunity for their testimony. The Supreme Court “solved” the trilemma again, in Gardner v. Broderick, by saying that an employee who is fired for invoking their Fifth Amendment right …
