Combined Middle Meningeal Artery Embolisation And Subdural Evacuation Port System Drainage For Chronic Subdural Haematoma: A Systematic Review, Single-Arm Meta-Analysis, Meta-Regression, And Cost-Benefit Analysis, Shiva A. Nischal, Santosh Guru, Shaan Patel, Ashviniy Thamilmaran, Mary Murphy

Department of Neurosurgery Faculty Papers

BACKGROUND: Chronic subdural haematoma (cSDH) is an increasingly prevalent condition in older, anticoagulated, and medically frail patients, in whom recurrence and perioperative risk remain substantial despite standard surgical evacuation. Growing recognition of cSDH as an angiogenic, inflammatory disorder has prompted interest in minimally invasive strategies that combine mechanical decompression with targeted modulation of the underlying vascular pathology. This study aimed to evaluate the safety, effectiveness, and health-economic profile of combined middle meningeal artery embolisation and subdural evacuation port system (MMAE-SEPS) drainage for cSDH, compared with conventional burr-hole evacuation.

METHODS: MEDLINE, Embase, and CENTRAL were searched from inception to 24th August …

Assessment Of Super Absorbent Polymer In Soybean Cultivation Under Variable Irrigation Conditions In Nebraska, Ankit Chandra, Abia Katimbo, Ronaldo Marchezan, Martha Nabaggala

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

Water limitation is a primary constraint to soybean productivity in both irrigated and rainfed systems. Soil-applied superabsorbent polymers (SAPs) have been proposed as a strategy to buffer crops against episodic drought stress; however, their physiological and agronomic performance under varying irrigation regimes remains insufficiently quantified. Here, we evaluate three biodegradable polymer formulations: broader granules (BB), original granules (OG), and powder (PWR) applied at low (17.7 lb/ac) and high (120 lb/ac) rates under full (100% ET), reduced (50% ET), and no irrigation conditions in western Nebraska. Polymer application had negligible effects under full irrigation, with yields comparable to untreated controls. Under …

Research On The Spatial Diffusion Process And Influencing Factors Of Traditional Chinese Medicine Brands: Evidence From Beijing Tong Ren Tang, Yuehua Shen

Dissertations and Theses Collection (Open Access)

Against the backdrop of the dual drivers of the revitalization and development of traditional Chinese medicine (TCM) and the rising demand for health-related consumption, the nationwide expansion of TCM chain brands has become a prominent issue of shared concern for both industry and policy circles. However, existing research largely treats cities as mutually independent units and overlooks the spatial externalities arising from geographic proximity. It also implicitly assumes that the driving factors remain stable over a brand's expansion life cycle. This makes it difficult to capture the dynamic evolution of the logic governing store expansion across different stages. Accordingly, this …

Uncertainty, Information, And Major Choice: Evidence From Chinese Gaokao, Sikun Dou

Dissertations and Theses Collection (Open Access)

An unresolved background risk makes people more averse to other, independent  risks—most of all when a high-stakes, irreversible choice must be made under that risk. College major choice is such a setting. In China, students are admitted directly into a major they cannot easily change, and in the early 2000s they had to commit before learning their exam scores, bearing a field’s academic risk on top of an unresolved admission risk. Because STEM fields carry more academic risk and women are on average more risk-averse, this burden falls hardest on women’s entry into STEM. Exploiting a reform that moved application …

Cannabinoid Modulation Of Metabolic Dysfunction Associated Steatotic Liver Disease In A Mouse Model, Kira Villarreal

Undergraduate Honors Theses

The liver plays an essential role in regulating metabolism. Though, when the physiology of the liver is thrown off, this can lead to pathological states. Metabolic dysfunction associated steatotic liver disease (MASLD) can be a consequence of irregular physiological state in relation to metabolism. MASLD is the leading chronic liver disease globally with estimated 30% of patients affected, and incidence rates expected to rise. MASLD is diagnosed when there is a >5% build up of lipids in the hepatocytes and is not associated with high alcohol consumption. There are many risk factors associated with MASLD, such as high fat or …

The Role Of Art-Based Pre-Performance Rituals For Collegiate Student-Athletes And Their Perceived Effects On Mental Preparation, Haylee P. Robinson

Undergraduate Honors Theses

This paper will explore whether collegiate student-athletes at the University of Northern Colorado (UNCO) engage with art-based pre-performance rituals (PPRs) and, if so, examine their perceived effects on mental preparation prior to competition. Research has discussed traditional preparatory routines (PRs)—breathing techniques, visualization, goal setting, and problem-solving—creating a gap for understanding how creative or symbolic rituals function in the realm of collegiate sports. Combining Clifford Geertz's (1973) anthropological framework of ritualized behaviors acting as “meaning-making systems” with empirical evidence supporting art therapy, this research positions symbolic art-based interventions as PPRs, helping athletes with focus, emotional regulation, and confidence prior to competition. …

The Impact Of The 2018 Zero Tolerance Policy On Children In The U.S Child Welfare System, Gabrielle Pelayo, Griselda Padron, Alexxis Garcia

Electronic Theses, Projects, and Dissertations

In 2018, the implementation of the Zero Tolerance Policy led to the forced separation of children from their parents at the United States/Mexico border, raising concerns about the potential effects on children’s attachment relationships and mental health. Guided by ecological systems theory and attachment theory, the study will explore how separation shaped children’s attachment relationships and mental health outcomes, and what these experiences reveal about gaps within the child welfare system’s capacity to respond effectively. The two guiding research questions are: (1) How have the experiences of children separated under the 2018 Zero Tolerance Policy influenced their attachment relationships and …

Electronic Theses, Projects, and Dissertations

Mass incarceration will have profound and disproportionate effects on Black and Latino families in the United States, extending beyond the incarcerated individual to impact family functioning, emotional well-being, and access to support systems. Rooted in structural racism and inequitable criminal justice policies, mass incarceration will contribute to long-standing social and economic disparities that will continue to shape the lived experiences of marginalized communities. This study will explore the psychological and social impacts of incarceration on Black and Latino families, with particular attention to emotional distress, family relationships, stigma, and resilience. Using a qualitative research design, the study will employ semi-structured …

Arrest Rates And Police Presence In East Bay Area Counties Of Northern California, Christiana M. Tyler

Electronic Theses, Projects, and Dissertations

In this research study, we discuss the social phenomenon of mass incarceration in the United States. Previous research has evidenced clear racial disparities within this social issue, but has yet to make a connection between high incarceration rates and the sheer volume of police officers in many communities. This descriptive study sets out to discover whether there is a difference in incarceration rates based on the level of police presence in select counties in Northern California. The study will measure police presence by the number of police officers, using secondary data from U.S. government and nonprofit agencies. The researcher hypothesizes …

Sleep Disturbances In Parkinson’S Patients With A History Of Head Injury, Melissa N. Pacheco

Electronic Theses, Projects, and Dissertations

Sleep disturbances are among the most prevalent and burdensome non-motor symptoms of Parkinson’s disease (PD), yet the contribution of prior traumatic brain injury (TBI) to these problems remains poorly understood. The purpose of this study was to examine whether the number and severity of lifetime head injuries predicted sleep disturbances in individuals with PD. Data from 3,055 PD patients enrolled in the Fox Insight study were analyzed, including 1,593 with a history of head injury. Participants completed self-report questionnaires assessing head injury history, motor and cognitive symptoms, and sleep disturbances. Generalized linear mixed models tested whether head injury history and …

Examining The Effects Of Boundary Management Practices Amongst Remote Workers In A Post-Pandemic World, Rosalia G. Casas

Electronic Theses, Projects, and Dissertations

With remote work on the rise after a world-wide pandemic, boundary management practices have been harder to establish for employees because of the high levels of integration that is seen when working from home. Identifying the impact that boundary management behaviors have on employees is important amongst remote workers because they are more often at risk for work-life spillover and conflict because of permeability between domains. This study looks at the relationship between work arrangements and employee outcomes such as work family conflict and job satisfaction with boundary preference and family supportive supervisor behaviors as moderators. Using linear regression models, …

Ableism In Higher Education: Platicas Framing Faculty Perception Of Student Accommodations And A Call To Action, Stephanie P. Rivas

Electronic Theses, Projects, and Dissertations

Academic ableism and traditional educational practices hinder the success of disabled students (Dolmage, 2017). As a student with disabilities, I have witnessed gradual improvements in the perception of disabilities in education. However, academic ableism persists in today’s higher education institutions, which can be disheartening for students like me, an unapologetically disabled person. This study employs framing theory, a communication theory that explains how people interpret and organize information (Goffman, 1947). These frames influence how accommodations are perceived, shaping attributes and connections between behaviors and potential causes (Tewksbury & Scheufele, 2019). Using platicas, a kind of cultural method of open conversational …

The Role Of Placement Experiences In Foster Youth Vulnerability To Commercial Sexual Exploitation, Viridiana Jauregui Estrada

Electronic Theses, Projects, and Dissertations

Youth involved in the child welfare system face a heightened risk of commercial sexual exploitation of children (CSEC), particularly those who experience placement instability or placement in congregate care settings. While existing research consistently documents the overrepresentation of foster youth among those impacted by CSEC, less attention has been given to how specific placement experiences function as mechanisms that shape vulnerability. Guided by the Complex Trauma Framework and the Socio-Ecological Theory, this study will examine how placement instability and placement type increase foster youths’ vulnerability to CSEC and explore the role of trauma-informed social work interventions in mitigating these risks. …

Inclusion And Equity In Early Childhood Special Education, Maranda Martinez

Electronic Theses, Projects, and Dissertations

The present study examined equity and inclusion in early childhood special education through the lived experiences of administrators, educators, and caregivers. Despite decades of legislation, preschool students of color with dis/abilities continue to experience disproportionate identification for special education, exclusionary discipline, and limited access to inclusive settings (DHHS & DE, 2023; NCD, 2018). Grounded in Disability Critical Race Theory (DisCrit), this study explores how intersecting systems of racism and ableism shape early childhood educational access and opportunity.

Guided by a phenomenological approach with a transformative paradigm, data were collected through semi-structured interviews with eighteen participants including administrators, early childhood special …

Impact Of Affirmative Care For Lgbtqsia2+ Youth In Foster Care, Jody Brown

Electronic Theses, Projects, and Dissertations

One of the major challenges within the child welfare system is that LGBTQSIA2+ youth often face discrimination, stigma and have limited access to mental health services. Although previous research has identified LGBTQSIA2+ youth being overrepresented in foster care, they face distinctive vulnerabilities that are inadequately addressed in present policies within child welfare practices. Despite experiencing higher levels of placement instability and being at greater risk of anxiety, depression and psychological distress, there remain gaps in tangible support and evaluating the effectiveness of intersectionality of lived experiences of LGBTQSIA2+ youth in the foster care. The purpose of this qualitative phenomenological research …

The Different Effects Of Housing First Policies On Homeless Men And Women With Substance Use Issues, John Carlin, Simon Ogom, Kimberly Quiles, Juan Zamudio

Electronic Theses, Projects, and Dissertations

Substance use is a prevalent issue in the homeless population, and in recent years, the homeless population has continued to grow. HF is a model where a homeless person is placed in housing with no preconditions. This model has been shown to be an effective tool in solving homelessness while also mitigating the rate of substance use in this population. However, there is no clear data on whether women benefit at the same rate as men in HF, and the majority of current studies are male-focused. Women often face unique issues like higher levels of assault while homeless, and it …

Beyond The System: A Critical Analysis Of Child Welfare Placement Practices For Children With Autism, Lauren Scott, Nicole Navarro

Electronic Theses, Projects, and Dissertations

Autism Spectrum Disorder (ASD) is a neurological condition that affects an individual’s communication, social interactions, and behavior. Approximately 1.7% of children in the United States are diagnosed with ASD. Families raising children with ASD face significant challenges, including limited support systems, caregiver fatigue, and financial strain. These difficulties increase the likelihood of maltreatment, leading to higher rates of children with ASD being referred to Child Welfare Agencies. Once involved in the system, children with ASD often encounter difficulties in finding appropriate long-term foster or kinship placements, which can result in high rates of placement instability. This research seeks to identify …

Girlhood, Interrupted: An Intersectional Feminist History Of Decolonizing And Reclaiming Womanhood, Ayden Kelly

Electronic Theses, Projects, and Dissertations

In the past few decades, social and political discourse surrounding womanhood and who is considered a "real" woman has led to the execration of transgender women. This work will explore how recent discourse and rhetoric surrounding who is and who is not a “real woman” can be traced to nineteenth century notions of “true womanhood” that excluded women of color. In the late 19th and early 20th centuries, with westward expansion, settler colonialism, residential schools, slavery, and post-emancipation serving as backdrops, this work will also analyze how ideologies of womanhood have interrupted and suppressed women of color throughout Western American …

Countering Anti-Immigrant Narratives: Promoting Socio-Emotional Well-Being Through Familism, Counter-Storytelling, And Community Building In Latinx Family Workshops, Sitlaly Irais Jimenez Preciado

Electronic Theses, Projects, and Dissertations

In recent decades, the United States has seen a growing anti-immigration climate marked by restrictive policies, racialized political rhetoric, and public discourse targeting immigrant communities. This environment has heightened fear, discrimination, and exclusion for immigrant families, especially those of Latinx origin, affecting daily life in schools, healthcare, and community spaces (Caballero et al., 2022; Roche et al., 2021). These families experience socio-emotional challenges, including anxiety, depression, and fear, alongside barriers to social and health services.

While research documents the harmful effects of anti-immigration policies and rhetoric on Latinx families, few interventions focus on protective factors that help Latinx families navigate …
