Cultivating Mindsets And Transformative Practices Of Beginning Alternative Certified Teachers: A Teacher Perception Study, Rodney Keith Wilkerson

Theses and Dissertations

The shortage of qualified teachers in the United States has been a persistent issue for decades. The number of qualified candidates to fill teaching vacancies has fallen short as the number of teachers needed to educate today continues to increase (Carothers et al., 2019). Traditionally, teacher preparation programs were the primary source of certified teachers. However, these programs have been decimated by declining student enrollment and by criticisms that they do not meet the needs of prospective teaching candidates today (Darling-Hammond, 2020). In recent years, the shortage has become even more acute, with some regions facing severe teacher shortages (Carothers …

The Assessment Of Implicit Bias Among Police Personnel: A Systematic Review, Emily Deutsch

Theses and Dissertations

Due to the essential and powerful role police officers play within the communities they serve, systematic racism in law enforcement has become a key topic of public discourse, including increased demand for evidence-based changes in police selection. This includes recommendations or requirements to assess implicit bias in police candidates (e.g., California Assembly Bill 846). Implicit bias refers to the spontaneous/automatic associations or evaluations made of members of a particular group (Kim & Roberson, 2021). The California Commission on Peace Officer Standards and Training’s (POST’s) Bias Assessment Framework provides recommendations to police psychologists on the assessment of implicit bias, but curiously …

Resilience And Stress: Trauma, Grit, Resilience And Perceived Organizational Support In First Responders, Paige Gallas Parker

Theses and Dissertations

First responders comprise an underserved and under-researched population, despite consensus that their work involves exposure to potentially traumatic events. Inconsistent definitions of “first responder” and unclear prevalence rates of posttraumatic stress symptoms (PTSS) limit efforts to assess and promote resilience. This study examined the relationships between grit, resilience, perceived organizational support, and trauma symptoms in a sample of 234 first responders (69% firefighters, 29% lifeguards) employed by a large West Coast fire department. Measures included a demographics questionnaire, the Professional Exposure to Traumatic Events (PETE), the Posttraumatic Stress Disorder Checklist (PCL-5), the Connor-Davidson Resilience Scale (CD-RISC-10), the Short Grit Scale …

Using a transformative mixed methods design, the researcher analyzes enrollment patterns, the intersectionality of race and gifted identification in K-5, and teacher and leader perceptions of how organizational routines influence student enrollment in advanced academic courses, grades 9-12, in a school district in West Central Georgia. Redacted student …

To Be Loved Is To Be Seen: Gazing As A Form Of Interpretation In The Turn Of The Screw, Yasmin Mezayek

Theses and Dissertations

The heated discourse that would follow Henry James’s novella “The Turn of the Screw” centered on whether the ghosts were real or not. With Shoshana Felman’s groundbreaking article “Turning the Screw of Interpretation” a new-found focus on the ambiguities, as opposed to finding a singular, definitive meaning of the novella would usurp the Freudian and anti-Freudian arguments. With the governess’s sight being the main source of debate, reading the novella through the Lacanian lens of the Gaze, the Imaginary, and the Symbolic offer unprecedented explanations and arguments for the governess’s behavior. Given the contemporary shift to discussing the ambiguities of …

Wiring Attachment, Alexander K. Bacon

Theses and Dissertations

This thesis began with a question: can diagrams create understanding, or only reflect it? Through paintings that layer automotive wiring schematics with family photographs, I explore how the human attachment system resists easy mapping. Using digital tools like Photoshop and scanning, alongside analog methods such as papier-collé and photo transfer, I examine how systems built for clarity—like wiring diagrams—contrast with the layered, often messy realities of human relationships. Drawing from attachment theory’s empirical foundation, rather than the metaphorical leanings of psychoanalysis, my work investigates how emotional bonds form, falter, and repair over time. Material loss and layering are not flaws, …

Multitask Learning For Named Entity Recognition And Relationship Extraction, Adrienne D. Hembrick

Theses and Dissertations

Information Extraction (IE) is a fundamental task in Natural Language Processing (NLP), involving the identification of structured information from unstructured text. Two core components of IE—Named Entity Recognition (NER) and Relation Extraction (RE)—are widely used to extract key concepts and the relationships between them across various domains. However, the sequential dependency of RE on the output of NER makes it vulnerable to error propagation: inaccuracies in entity recognition can negatively affect downstream relation extraction.

To mitigate this issue, Multitask Learning (MTL) has been proposed as an approach that jointly models NER and RE, aiming to improve overall performance and reduce …

Theses and Dissertations

This research paper examines the factors influencing individual preferences for vehicle emissions and inspection programs. Drawing on the Value-Belief-Norm theory and Rational Choice Theory, the study examines how environmental attitudes, concerns, and the cost of inspection programs shape an individual’s support. The study analyzed survey responses from 326 individuals at Illinois State University and found that individuals with greater environmental concern and belief in the effectiveness of emissions testing were more likely to support requiring annual vehicle emissions and inspection programs. Furthermore, funding the cost of vehicle emissions and inspections through state taxes, rather than requiring individual vehicle owners to …

Investigating Heterogeneity Of Hydraulic Conductivity And Its Influence On Groundwater Flow Dynamics Within A Saturated Riparian Buffer In Central Illinois, Joseph L. Awuku

Theses and Dissertations

The use of Saturated Riparian Buffers (SRBs) in agricultural settings as a means of reducing contamination of surface water and groundwater resources has gained popularity due to their trapping ability and solute removal (nutrient recycling) capacity. In light of SRB’s nutrient-trapping and removal ability, numerous studies have been conducted to characterize the effectiveness of SRBs. However, most studies on SRBs have paid minimal attention to heterogeneity of hydraulic conductivity (K) and groundwater flow dynamics within SRBs. This study investigated the heterogeneity in horizontal K and estimated the vertical groundwater-specific discharge (q_v) between the upper weathered and its …

With a focus on how perceptions of race and socioeconomic class interact to influence friendships and peer acceptability, this study examined the social experiences of Black males with academic potential who come from low-income families. Using Critical Race Theory (CRT), Du Bois’ concept of double consciousness, and the framework of racial opportunity cost as guiding frameworks, the study examined how “smartness” functions as a cultural practice tethered to whiteness and how these dynamics affect identity and belonging.

This study was conducted using a qualitative research design, leveraging an interpretivist paradigm. To extract the stories of the research participants, semi-structured interviews …

The Impact Of Coaching On Teachers' Implementation Fidelity Of Goal Setting Strategy, Brandi M. Greene

Theses and Dissertations

Educational settings are filled with educators who have varying experiences in working with students who have disabilities and students who are considered at-risk. Typically, students who have disabilities or are considered at-risk struggle with self-regulation skills and require interventions to improve. However, literature has shown that there is very little training for teachers that will help them implement evidence-based strategies with fidelity. One of the strategies that can be used to improve self-regulation is goal setting, however, within the literature for the goal setting strategy, teachers are not well equipped to implement the strategy. Coaching has been deemed an effective …

Utilization Of Golden Pennycress In Broiler Diets, Marley M. Knowles

Theses and Dissertations

The objective of this study was to evaluate performance in broiler chickens fed diets containing golden pennycress meal (GPCM), with and without a flavor additive. Golden pennycress (Thlaspi arvense) is a winter cover crop grown in the Midwest that is rising in popularity as a cash crop used for biofuel production. After oil is pressed out of the seeds, a meal remains that is usually discarded. Incorporation of this meal (23% protein, 15% fat) into feedstuffs for broilers would be an efficient way to make biofuel production more sustainable. In one study, Cornish Cross three-day-old chicks (n=12) were …

Listening To The Body: Attunement And Advocacy In Women's Experiences Of Endometriosis, Rebekah E. Greenslaugh

Theses and Dissertations

Endometriosis is a chronic, inflammatory condition in which tissue similar to the endometrial lining grows outside the uterus, leading to severe pain, fatigue, and other debilitating symptoms. Despite its significant impact on daily life, many women with endometriosis report that their symptoms are dismissed in medical encounters, as their pain is minimized or normalized as an inherent aspect of womanhood. This medical dismissal, combined with a lack of definitive diagnostic tools and effective treatments, leads many to turn to online support communities to make sense of their symptoms, share experiences, and develop ways to cope with the condition. Drawing on …

The Biomechanics Of Braking Squat And Split Braking Squat: An Experimental Approach, Ariel Atias

Slovakian immigrants represent one group whose presence in the U.S. has not been studied. This thesis investigates how Slovakian immigrants navigate their immigration experience in the aftermath of what is known as the Velvet Divorce, focusing on economic-driven and family-driven migration and transnationalism. Using a qualitative approach, data were collected through ten semi-structured interviews with Slovakian immigrants within the greater Chicago area. The informants in this study recalled their reasons for leaving Slovakia, which …

Investigation Of The Human Temporal Styloid Process As A Bony Indicator Of Speech, Sommer A. Martin

Theses and Dissertations

The temporal styloid process in humans serves as an attachment point for the styloglossus, stylohyoid, and stylopharyngeus, which are involved in tongue movement and deglutition. I hypothesized that the length of the ossified styloid process in humans is the result of selection for increased musculature that would support tongue movements involved in speech. This hypothesis assumes that the relative length of the ossified temporal styloid process is unique to humans. A comparative analysis of the presence or absence of the temporal styloid process was conducted on ten genera of Old-World primates, and it was found that the length of this …

Skin And Bones: Transgenerational Trauma, Experimental Storytelling, And The Texture Of Hope, A Creative Dissertation, Janine Blue

Theses and Dissertations

This dissertation theorizes and enacts experimental storytelling as a method for engaging transgenerational trauma, highlighting how form shapes the ways histories are remembered, embodied, and reimagined across generations. Grounded in hope rehearsal as both a theoretical and creative framework, this project examines how BIPOC writers use experimental writing techniques to navigate the afterlives of historical trauma and reclaim storytelling as an act of meaning-making, communal care, and futurity. The dissertation begins with a critical chapter that explores these experimental techniques as strategies for recovery and resistance. The dissertations’ creative chapter, Andre Lyle: Skin and Bones, expands on these ideas …

High Throughput, Solid Sample Analysis With Cone-Based Mass Spectrometric Ionization Sources, Emily J. Wiggins

Theses and Dissertations

The widespread presence of environmental and consumer-product contaminants (e.g. trace metals, opium alkaloids) has underscored the need for rapid, reliable, and high-throughput analytical techniques that are capable of handling complex solid samples. While traditional mass spectrometric (MS) methods tend to have high sensitivity and accuracy, they often require labor-intensive and time-consuming sample preparation steps that limit throughput and field applicability. This thesis investigates the use of 3D-Printed Cone Spray Ionization-Mass Spectrometry (3D-PCSI-MS) as an ambient ionization technique for the direct screening of contaminants from solid matrices, eliminating the need for traditional sample preparation and allowing for real-time analysis.

Precipitation Forecast And Verification For Suas Applications, Patrick Britt

Theses and Dissertations

Small Unmanned Aerial Systems (sUAS) have become a fast-growing part of air traffic in the United States. This significant growth is due to the numerous uses these systems can provide, both recreationally and professionally. Due to the small nature of the sUAS, any weather, regardless of intensity, plays a vital role in flight operations and planning. In a survey of sUAS pilots, it was found that precipitation was the most significant hazard of concern, and the most time-sensitive hazard, as precipitation conditions are most often checked by operators in the immediate moments before flight. This project aimed to create, analyze, …

Hillslope Degradation: Coarse Sands May Move Faster But Fines Dominate Flux, Robert Chance

Theses and Dissertations

Hillslopes are one of the most pervasive landforms on Earth yet the details of the processes that drive their evolution are not completely understood. Excluding boulders, the majority of mass and volume in soil-mantled hillslopes is composed of sand-sized and finer grains. Understanding the transport rates and governing transport mechanisms of these grains is therefore key to advancing our knowledge of hillslope evolution.This research investigates sand-sized sediment transport through field experiments at 20 sites tracking surface sediment motion and 11 sites measuring depth-dependent transport. These empirical results are compared against outputs from a novel grain-based hillslope diffusion simulation (GBHDS), which …
