Comparing Error Correction Strategies In Discrete Trial Training For Children With Autism, Rachael Litchford

All Graduate Theses and Dissertations, Fall 2023 to Present

Children diagnosed with Autism Spectrum Disorder (ASD) often require structured, evidence-based teaching methods to promote skill acquisition. Discrete Trial Training (DTT) is one such approach widely used in Applied Behavior Analysis (ABA) to teach skills through repeated learning opportunities. However, limited research has compared the efficiency of specific error correction procedures within DTT. This study examined the comparative effectiveness of two error correction strategies, Active Student Response (ASR) and Model-Only, when acquiring tacting skills for children ages 2-10 with ASD. An alternating treatments design (ATD) was used to evaluate each strategy’s impact on skill acquisition, as measured by the percentage …

The Influence Of Shape Complexity And Exploratory Behavior On Grasping, Mckenzie Gunter

Dissertations

People can orient and configure their hands in many ways in order to grasp objects. The current study investigates how object shape and hand placement influence graspability of objects, and how experimentally imposed constraints on grasping type alter grasping behavior. In a recent study, Gunter and Hajnal (under review) found that the ratio of object curvature and maximal handspan is the variable that defines the affordance of graspability. The current study aims to extend these findings by employing a more precise measurement of finger placement in two experiments using 3D printed objects as stimuli. To capture varying complexities of object …

Vulnerability In The Dark Triad: Insecure Attachment And Relational Aggression In The Peer Relationships Of College Students, Summer Boggs

Dissertations

Research on relational aggression (i.e., a type of aggression in which the aggressor harms others by damaging their relationships, reputation, and/or feelings of social acceptance) with college students has identified several important correlates, including anxious and avoidant attachment styles. Moreover, the personality traits captured by the Vulnerable Dark Triad (VDT; i.e., borderline, the antisocial component of psychopathy, and vulnerable narcissism; Miller et al., 2010) have demonstrated positive relationships with both relational aggression and insecure attachment. This study examined the relationship between insecure attachment and relational aggression among college students (N = 560), testing VDT traits as partial mediators of …

Implementation Of Phq-9 To Improve Depression Identification In Icu, Jenny C. Manoly Bsn, Rn

Doctor of Nursing Practice Final Project Abstract

PURPOSE This quality improvement project aimed to improve depression identification by screening 80% of eligible adults admitted to two heart failure intensive care units (ICU) using the Patient Health Questionnaire-9 (PHQ-9).

RESULTS Screening compliance increased from 42.1% to 85% by Week 13, exceeding the project goal. Of 101 patients screened, 16.8% screened positive for depression. Workflow changes, leadership support, and peer engagement improved compliance, though psychiatric referrals remained inconsistent.

BACKGROUND Depression is common among critically ill patients but is frequently underrecognized because ICU care primarily focuses on physiologic stabilization. Existing admission screening was limited to suicide risk assessment, delaying identification …

Impact Of Chronic Stress And Nutrition On Functional Connectivity And Neural Networks In Young Kichwa Children From The Ecuadorian Amazon Rainforest, Matthew L. Cook

All Graduate Theses and Dissertations, Fall 2023 to Present

Early childhood is a critical period for brain development. Positive and negative experiences during this time can have lasting effects on learning, health, and well-being. However, most research on children’s brain development has been conducted in wealthy, industrialized nations, leaving important gaps in our understanding of how children develop in other cultural and environmental contexts.

This study examined brain development in Indigenous Kichwa children living in two rural communities in the Ecuadorian Amazon Rainforest. The goal was to better understand how chronic stress and nutrition may influence a child’s developing brain during early childhood. Children participated in noninvasive brain assessments …

Challenges To Longevity Among Native Americans In The Four Corner States, Ashley Lenarz

All Graduate Theses and Dissertations, Fall 2023 to Present

Previous research has shown that Native Americans within the Four Corners States of the United States experience poor health outcomes and premature mortality.

Research examining COVID-19 pandemic outcomes has also suggested that Native peoples within the Four Corners States have been especially hard hit with high rates of infection and mortality. Our research seeks to (1) understand how life expectancy trends and differences changed among non-Hispanic Native Americans and Whites in the Four Corners States during the COVID-19 pandemic and (2) examine how much of these trends and differences …

Investigating Recruitment Bottlenecks Of Juvenile Native Fish In The Colorado River Basin, Utah, Anna R. Amidon

All Graduate Theses and Dissertations, Fall 2023 to Present

The first year of life is a vulnerable period for most fish species. Whether young fish survive this early stage determines how many individuals eventually survive and grow into reproductive adults, a process called recruitment. In desert rivers like the Colorado River Basin, native fish evolved alongside extreme natural conditions but now face additional pressure from drought and water storage infrastructure, which alter the shoreline habitats on which young fish depend. Long-lived, migratory native species with complex life cycles are especially vulnerable. We used four decades of monitoring data from the Upper Colorado River Basin to evaluate whether young-of-year (YOY, …

Mindful Classrooms: Teachers Co-Designing And Implementing Mindfulness Interventions, Mary L. Phan

All Graduate Theses and Dissertations, Fall 2023 to Present

The Influence Of Habitat And Individual Specialization On Mountain Lion (Puma Concolor) Hunting Strategy In A Multi-Prey System, Hannah B. Klugman

All Graduate Theses and Dissertations, Fall 2023 to Present

There is a growing recognition that animal species considered generalists (having a broad and varied diet), are actually specialists, a collection of individuals with different preferences and strategies known as specializations. The diet of a specialist depends on the variety and quantity of available food options, and their own ability to take what they need. Mountain lions (Puma concolor) are known for their ability and tendency to hunt large prey, such as elk (Cervus canadensis) and mule deer (Odocoileus hemionus), but despite the fact they overlap with other potential large prey, like feral horses …

Cultural Humility In Motion: A Graduate Student Hybrid Immersion In Self- And Other Awareness Through Dance, Emily Jeanne Slater

All Graduate Theses and Dissertations, Fall 2023 to Present

Universities bring together people from many different backgrounds, identities, and experiences. Yet university spaces often focus on mind-centered and discussion-based learning and overlook how the body plays a role in education. When education ignores the bodily experience of learning, students lose opportunities to reflect, connect, and make meaningful change in their lives and communities. To address this gap, this dissertation designed and implemented a learning experience for graduate students that creates space from them to examine their own assumptions, engage across differences, and share in inclusive practices. The learning experience draws on and advances cultural humility theory, which understands self-awareness, …

Drought And Diet Breadth: Does Insect Specialization Influence Herbivory When Plants Are Under Stress?, Jakob Palmer

All Graduate Theses and Dissertations, Fall 2023 to Present

Climate change will alter precipitation worldwide, causing more frequent and severe drought events worldwide. Drought affects many ecological processes, including plant-herbivore interactions, which are critical to biodiversity and ecosystem health. A variety of plant characteristics can influence herbivory – such as how hairy, nutritious, or toxic a leaf is – and drought has been shown to alter many of these traits. Unique characteristics of herbivore species are also important: herbivores can either feed on a variety of plants (generalists) or a group of closely related plants (specialists). Specialists can cope with traits of the plants they eat, while generalists are …

A Social-Ecological Systems Approach To Integrating Outdoor Recreation And Black Bear Management: A Michigan Case Study, Megan Dorothy Stone

All Graduate Theses and Dissertations, Fall 2023 to Present

Outdoor recreation sits at the intersection of social and ecological systems, representing one of the primary ways in which humans directly interact with their natural environment. As a result, outdoor recreation management must balance providing high-quality outdoor recreation opportunities while simultaneously protecting natural resources in protected areas. Balancing these concurrent management goals has become more challenging in recent years as participation in outdoor recreation increases. This can lead to numerous negative impacts on the environment, such as wildlife disturbance. In this study, I explore the challenges and opportunities for collaboration between managers of outdoor recreation and black bears in the …

Evaluating Data Management Practices And Ontology Development For Transportation Safety Assets, Brig Dean Adams

All Graduate Theses and Dissertations, Fall 2023 to Present

Data has begun to permeate transportation agencies, with every process, asset, and event generating a great volume of data. This data helps engineers and decision makers determine maintenance schedules, devise infrastructure investment strategies, improve safety, and plan for future needs. Due to the size of transportation agencies and the diversity of the data they collect, their data is often stored in different systems, managed by different groups, and described using inconsistent terminology. These challenges make it difficult to locate information, combine data from multiple sources, and confidently use data to support important decisions.

This research examined how transportation safety asset …

Behavioral And Landscape Factors Affecting The Effectiveness Of Egg-Bait Management For Common Ravens In The Great Basin, Usa, Sierra L. Pederson

All Graduate Theses and Dissertations, Fall 2023 to Present

Common Ravens have become increasingly common across the Great Basin of the western USA, largely because human activities, such as roads, agriculture, livestock operations, and human-made structures, provide them with abundant food, water, and nesting sites. As raven numbers have grown, so has their impact on vulnerable species like the greater sage-grouse. Like many other ground-nesting species, greater sage-grouse eggs and chicks are especially susceptible to predation. To help reduce raven numbers in sensitive areas, wildlife managers often place hard-boiled chicken eggs treated with a toxin (DRC-1339) on the landscape, expecting that ravens will die after eating these eggs and …

Public And Self-Stigma Toward Mental Health Among Individuals Of Mexican Heritage, Mitzi Escalante

Theses & ETDs

There are rising concerns about social isolation and declining mental health that have prompted increased attention to the role of culture in shaping mental health experiences, particularly through stigma. Although prior research suggests that mental health stigma varies across and within cultural groups, limited work has focused specifically on Mexican American populations. The present study examined the relationship between Mexican American cultural values and both public stigma and self-stigma toward mental illness. Measures included the Mexican American Cultural Values Scale (MACVS), the Community Attitudes toward the Mentally Ill scale (CAMI) to measure public stigma, and the Internalized Stigma of Mental …

Issue 26: Labour, Poverty, And Health Concerns Of Migrant Women And Girls Working As Kayayei In Ghana's Urban Centres, Comfort Baidoo, Robert Mcleman

International Migration Research Centre

Over the past four decades, growing numbers of women and girls have left northern Ghana for the country's cities, drawn by the promise of work, independence, and a chance to support their families. Many end up as kayayei, head porters who carry goods through Accra's crowded markets for a negotiated fee. Their labour keeps the informal economy moving, yet it comes at a steep personal cost: unpredictable earnings, punishing physical strain, unsafe housing, and a healthcare system that too often leaves them out. This brief draws together the available evidence on the economic and health conditions of kayayei in Greater-Accra. …

Content Mapping: An Experimental Analysis Of Missing Message Content, Jeannette Sutton

Emergency Preparedness, Homeland Security, and Cybersecurity Faculty Scholarship

The Warning-Response Model recommends the inclusion of five key content areas in warning messages to reduce information seeking that can lead to warning response delay: the message source, hazard (including its impact), affected location, recommended guidance, and time. Research has found that complete messages, that is, those that include all of five recommended content areas, help people make decisions about the protective actions they may take.  Unfortunately, a large majority of WEA messages omit information from one or more of the recommended content areas. This study examined the impact of omitting each of the five recommended content areas on message …

Human-Centered Electric Vehicle Adoption Framework For Smart Mobility: Modeling Perceived Range And Charging Anxiety As A Psychological Barrier, Fatemeh Nazari, Abolfazl (Kouros) Mohammadian, Thomas Stephens

Civil Engineering Faculty Publications

Electric vehicles (EVs) offer a transformative pathway toward reducing the environmental, economic, and health-related externalities of internal combustion engine vehicles in urban settings. Despite substantial advances in battery technology, charging infrastructure expansion, and supportive policy incentives, EV penetration remains limited which poses challenges for smart and sustainable mobility planning. A critical yet insufficiently modeled barrier to adoption lies in the psychological perceptions surrounding electric driving range and charging reliability, which is commonly framed as “range anxiety,” but more broadly reflecting perceived range and charging anxiety. To address this gap, this study introduces a latent psychological construct capturing individuals’ perceived range …
