Lessons Learned: Commissioning An Fgd Wastewater Treatment System, Bella Triolet, Mckale Grant, Louis Manigault

World of Coal Ash Proceedings

Stantec recently supported commissioning a flue gas desulfurization (FGD) Wastewater Treatment System in accordance with the 2020 Environmental Protection Agency (EPA) Effluent Limitations Guidelines (ELG) Rule, which requires that coal fired power plants meet their more stringent requirements by December 31, 2025. With the addition of the 2024 EPA ELG Rule, coal fired power plants will now be expected to move to zero liquid discharge (ZLD) systems or permanently cease coal combustion by 2034. Due to this change, it is likely that coal fired power plants will be looking to design and install ZLD systems within the next decade. While …

Breaking The Cycle: The C.A.R.E. Manager Model To Address Intergenerational Incarceration, Amber Pelan, Miranda Jacobsen

Criminology and Criminal Justice Theses and Dissertations

Generational incarceration is a significant social problem in which criminal justice involvement is repeated across multiple generations of the same family. Children of incarcerated parents face elevated risks of trauma, poverty, educational disruption, mental health challenges, and later justice system involvement. These patterns demonstrate that incarceration often harms the entire family rather than only the individual offender. This project examines why generational incarceration occurs and identifies strategies to interrupt the cycle. The project uses a literature review methodology to integrate criminological 4 theory, sociological research, and policy analysis. These theories explain how parental incarceration disrupts child development, weakens family bonds, …

Proactive Violence Prevention: A Universal Bi-Annual Violence-Needs Assessment Tool For Grades K-12, Millie Fritzler, Emily Linehan

Criminology and Criminal Justice Theses and Dissertations

“Violence prevention begins in the high chair, not the electric chair” (Reiner, as cited in Davis et al., 2002). Two elements are essential to successful violence prevention: interventions that start early and interventions that are consistent (Davis et al., 2002; Dodge et al., 2015). The first five years are crucial for development; therefore, violence prevention needs to happen as early as possible to identify and address potential risk factors before harmful behaviors become reinforced (Davis et al., 2002). Despite this knowledge for the need for early violence prevention, schools still lack a truly proactive, universal system for identifying violence-related risk …

Physical, Environmental, And Psychological Determinants Of Sleep Among Long-Distance South Asian Caregivers Of Older Adults: A Mixed-Methods Approach, Srujana Chekuri

Gerontology Theses, Dissertations, and Student Creative Activity

Long-distance caregiving is an increasingly common yet understudied form of family care, particularly among immigrant communities whose cultural expectations of flial responsibility remain strong despite geographic separation. Among South Asian caregivers of older adults, caregiving across borders is shaped by powerful norms of duty, emotional endurance, and family obligation, creating distinctive patterns of stress that may profoundly afect health. One of the most consequential but underexamined outcomes of this caregiving context is sleep. This mixed-methods dissertation examined the physical, environmental, and psychological determinants of sleep among long-distance South Asian caregivers of older adults living in the United States. Guided by …

Transition To Noninvasive Testing From The Gold Standard Of Liver Biopsy, Heidi Bien, Sabina Choudhry, Christine Pocha, University Of South Dakota Sanford School Of Medicine & Avera Health System

Scholarship Pathways Program

Purpose: Metabolic dysfunction–associated steatotic liver disease (MASLD), formerly known as non-alcoholic fatty liver disease, represents a rapidly growing public health concern, affecting roughly 30% of the global population. MASLD encompasses a spectrum from simple steatosis to its more progressive form, metabolic dysfunction–associated steatohepatitis (MASH). Early and accurate assessment of liver disease is critical for risk stratification and management, yet the current gold standard-liver biopsy remains invasive, costly, and limited by sampling variability and interpretive subjectivity. Noninvasive imaging modalities, particularly magnetic resonance elastography (MRE), have emerged as promising alternatives, but their concordance with biopsy in real-world clinical practice remains underexplored.

A Restoration By Mangroves: Marilao And Pasig River Plan For Restoration, Julian Luis Flores

Student Theses 2015-Present

This paper discusses the restoration of the Pasig Rivers of the Philippines using the wondrous magic of mangrove trees to bring back various aquatic, flora, and bird species. The Pasig River was once the Philippines’ most beautiful river, spanning the entire Metro Manila, with different floral species blooming, teeming marine life, and being a significant transportation route. However, throughout the years, urbanization has caused the state of the river to decline drastically. Improper waste segregation, disposal, and improper river maintenance have given it the title “Manila’s toilet.” This is why it is essential to restore the river to its status …

Environmental Law, Travis M. Trimble

Mercer Law Review

In 2025, in a Clean Water Act (“CWA”) citizen-suit challenge to a landowner’s filling of a tract of land on St. Simon’s Island, Georgia, under a nationwide dredge-and-fill permit issued by the United States Army Corps of Engineers (the “Corps”), the United States Court of Appeals for the Eleventh Circuit held that the landowner did not waive its right to challenge whether the tract was a wetland by virtue of submitting a form to the Corps in connection with its obtaining coverage under the permit that stated that the landowner accepted that the tract at issue was a jurisdictional water …

Real, Not Rhetorical: Children’S Rights As The Strongest Constitutional Defense Of Obergefell Against Religious-Liberty Challenges, Tanya Washington

Mercer Law Review

Justice Kennedy’s decision to center adults’ rights in the Obergefell majority opinion—despite his awareness of children’s legal vulnerabilities—created space for Justice Thomas, in his Davis statement, to ignore children altogether and to reframe the constitutional question as a clash between adults’ rights: the right to marry and to be free from discrimination versus the right to exercise one’s religious beliefs and to refuse to engage in conduct that abrogate those beliefs. This distorted constitutional framing eclipses entirely the rights of children in same-sex families and the concrete harms they will face if their parents are barred from marrying—harms that provide …

Assessing College Tuition And Wage Prospects For Careers In Archaeology, Angelina H. Gutierrez

Honors Capstones

The pressures of rising college tuition are raising questions about whether a degree in higher education is worth the return on investment in today's society and economy. This study aims to acknowledge the issues of affording college and the opportunities granted in the face of college wealth premiums from the perspective of the field of archaeology. The college wealth premium is understood as additionalopportunities and increased salaries offered to those with a degree in higher education compared to those without. Using the Midwestern United States as a case study, I discuss the gender/race wage gap, college debt, loan inequity, and …

Skeletal Muscle Characteristics Long-Living Dwarf Mice In Response To High Fat Diet, Landon Schumacher, Matthew Johnston, Jaspreet Osan, Holly Brown-Borg

Arts & Sciences Undergraduate Showcase

Introduction: The effects of high fat diet (HFD; 60% kcal: fat) on skeletal muscle in mice with postnatal growth hormone deficiency is relatively unknown. We compared the tibialis anterior (TA) muscle from middle aged female Ames Dwarf and Wildtype mice fed HFD for 16 weeks and standard diet (STD; 10%: fat) to see the impacts of a HFD on inflammation and fibrotic formation in the musculature.   Methodology: Mice were euthanized after diet duration (age 10-12 months), and TAs were collected and frozen in OCT for cross-sectional cryosection. Ten um thick muscle was fixed to slides and stained with Oil Red-O …

From Sunshine To Sight Lost: Amd In North Dakota, Sidney J. Leciejewski, Diane Darland

Arts & Sciences Undergraduate Showcase

Age-related macular degeneration (AMD) is a progressive eye disease that directly harms the macula, which could eventually cause vision loss. The macula is an area on the back of the eye that contains cone cells, which allow for our color vision. Its location also allows us to have our central vision. There are two kinds: the dry and wet form, where the wet form is more extreme. The disease, itself, is highly prevalent in North Dakota, which is why it is important to note its causes and prevention methods. Some causes of AMD include genetic risks,  health risks, and metabolic …

Monotone Traveling Waves In A General Discrete Model For Populations With K-Generation Long-Term Memory, Austin Kernel Sanders

Theses and Dissertations

We investigate the spatial dynamics of a population modeled by a general discrete integrodifference equation incorporating k-generation long-term memory. While classical models rely solely on the im- mediately preceding state to determine population growth and dispersal, introducing multiple past states causes the associated evolution operator to lose compactness. Consequently, standard fixed- point theorems are insufficient to prove the existence of traveling wave solutions. We overcome this difficulty by constructing a time-independent moving frame operator and employing the monotone iteration method. By assuming the fecundity function is locally Lipschitz, bounded, and nondecreasing on a specified interval, and by relaxing continuity requirements …

Working Alliance And Subjective Engagement With A Digital Avatar Cbt Platform (Ritch®Cbt): Comparing Young Adults With And Without Co-Occurring Substance Use And Depression, Victoria Pezzino, Cassandra Berbary, Courtney Mckinney, Celeste Sangiorgio, Emi Moriuchi, Korena S. Klimczak, Robert Kay Cooper Jr., Wonkyung Kniffen, Maya Hareli, Cory Crane, Caroline J. Easton

Psychology Student Research

Digital mental health interventions (DMHIs) can help bridge treatment gaps experienced by young adults with co-occurring substance misuse and depression. However, it remains unclear whether engagement with these interventions differs for young adults with co-occurring conditions compared to those experiencing substance misuse or depression alone. To investigate this issue, we assessed working alliance and subjective engagement with a digital avatar-assisted cognitive-behavioral therapy (CBT) treatment platform (RITch^®CBT), comparing young adults with substance use, depression, and the co-occurrence of the two. A secondary data analysis was conducted on a sample of 99 young adults aged 18–28 years who presented at …

Comparative Behavioral Impacts Of Neuroactive Pharmaceuticals On Crayfish Locomotion, Grace Elizabeth Smith

Masters Theses

Pharmaceuticals are increasingly recognized as contaminants of concern in aquatic ecosystems, often entering waterways due to incomplete removal by wastewater treatment plants. Despite frequent detection, the effects of these compounds on non-target, neurochemically sensitive organisms such as crayfish remains underexplored. Gabapentin, an anticonvulsant that binds to presynaptic voltage-gated calcium channels and reduces excitatory neurotransmitter release, is one such emerging contaminant. Given crayfish’s ecological importance and sensitivity to neuroactive substances, exposure to gabapentin may disrupt key behaviors such as locomotion. To place gabapentin’s effects in context, we also examined escitalopram (Lexapro), a selective serotonin reuptake inhibitor that elevates synaptic 5-HT, and …

Self-Rated Mental Health As A Predictor Of Five-Year Incidence Of Heart Conditions, Cancer, And Dementia, In Post-Menopausal Women From Nshap Rounds 2 And 3, Annelie M. Persson

Gerontology Theses, Dissertations, and Student Creative Activity

Population aging is accompanied by a rising incidence of chronic disease, highlighting the need to identify early indicators of disease risk to support prevention and delay onset. Mental health has gained attention as a potential predictor of health outcomes. Self-rated mental health (SRMH) has emerged as a validated measure capturing resilience, social support, and overall outlook. Few studies in older adults have examined the relationship between SRMH and incident chronic disease. Although mental health is associated with behavioral and psychosocial factors such as physical activity and happiness, these pathways have rarely been examined as mediators. Self-rated physical health (SRPH) is …

Clethra Alnifolia: A Fact Sheet For Seed Transfer Considerations, Taylor Houggy

Plant Science Articles

Clethra alnifolia is a highly prized fragrant deciduous shrub, often found in many home gardens across Eastern North America. Despite its popularity in the landscape industry, there is little research comparing C. alnifolia's natural habits in the wild to its habits as a landscaped cultivar. Information such as flowering phenology, genetic diversity, and growth habits have the potential to change considerably depending on C. alnifolia's location. Because of this, it is important that landscape growers as well as forest conservationists have access to ecological fact sheets in order to make informed decisions when transferring seed to different areas. In this …

From Stranger To Self: The Role Of Familiarity In Modulating The N170 And N250 Erp Components, Tabish Gul

Dissertations

This study investigated how varying levels of face familiarity modulate the N170 and N250 event-related potential (ERP) components, two neural markers of face perception and recognition. While the N250 is widely considered familiarity-sensitive, the N170 has traditionally been linked to the structural encoding stage of face perception. However, recent research suggests that face familiarity may also influence N170 amplitude and latency. While most previous studies have compared up to three familiarity levels, the present study examined five levels of familiarity: own face, friend’s face, famous face, experimentally familiar face, and unfamiliar face. Twenty-six participants viewed face images while completing a …

Brachial Macroparasite Loads In Estuarine Young-Of-Year Striped Mullet (Mugil Cephalus), Triston Rice

Honors Theses

Climate change is a growing threat to marine habitats globally. One ecological impact that warming water temperatures poses is the increased metabolic rate of many parasite species. Their promoted reproductive and feeding rates could pose a threat to the stability of many host populations. Parasites of the gills, or brachial parasites, are especially concerning to fish populations globally. As parasitism is not limited to a specific taxon and comprises a large diversity of ecomorphs and behaviors, geographically distinct areas may be differentially affected by the changing prevalence of parasites. This study aimed to survey current brachial parasite abundance and prevalence …

Neuroprotective Effects Of Estradiol And Genistein And Interactions With Aromatase Inhibitions Post Cerebellar Lesion In Male Zebra Finches, Grace E. Thompson, Anthony P. Irovic

Honors Theses

Across vertebrates, peripheral and brain-derived estradiol (E₂) promotes neuroplasticity. After injury, E₂ can be derived locally from testosterone via aromatase (AROM), an enzyme that is upregulated in glia at the site of neural injury. E₂disrupts testicular function and elevates cancer and stroke risk, primarily via binding to estrogen receptor alpha (ER α). Genistein (GEN), a phytoestrogen, is similar to E₂ but binds preferentially to estrogen receptor beta (ER β). It may offer neuroprotection without adverse effects of E₂. We used adult male zebra finches (ZF) to model neuroprotective effects of E_{2 …}
