The Contribution Of Task Difficulty And Adult Reliability On Children's Academic Task Persistence, Ella M. Wheelbarger

Psychology Theses & Dissertations

Task persistence plays a crucial role in children's academic success and achievement of long-term goals. Contextual variables may influence child persistence such as reward source reliability, task difficulty, or task arrangement. We evaluated the effects of reward source reliability on children's academic task persistence with task difficulty. The perception of the reliability of the reward source was manipulated by making a commitment to provide a reward after completion of the task, but upon completion, delivery was delayed to the next day. The study was designed to examine the extent to which experiencing prior disappointments would decrease persistence times on subsequent …

Route 420: An Examination Of Cannabis Knowledge, Attitudes, And Use Behaviors Among Young Adults By Primary Route Of Administration, Samantha A. Fitzer

Psychology Theses & Dissertations

Cannabis use among young adults in the United States has reached unprecedented levels in recent years. Previous research suggests that the escalating legalization of cannabis across the U.S. has made cannabis use more socially acceptable as well as accessible (e.g., expanding routes of administration) to young adults. However, less is known about how combined individual-level factors (i.e., knowledge and attitudes) may predict cannabis use patterns among young adult college students. Using the Knowledge-Attitude-Behavior (KAB) model, the current study examined a) the mediating effect of cannabis beliefs on the association between cannabis knowledge and cannabis use behaviors (frequency and typical intoxication …

A Formal Simulation Model For Discrete Rate Simulation, Thomas J. Tracey

Electrical & Computer Engineering Theses & Dissertations

Simulation is an essential tool for virtualizing systems by creating a representative model of real or hypothetical systems and observing how they change over time. Two predominant simulation paradigms include Discrete Event Simulation (DES) and Continuous Simulation, which both have their strengths and weaknesses. DES does not handle continuous state variables, while continuous simulation handles continuous state variables but encounters errors where these variables have discrete changes in their behavior. This difficulty between the two predominant simulation paradigms prompted the creation of a new simulation paradigm to cover this gap: Discrete Rate Simulation (DRS). DRS as a simulation paradigm focuses …

Nontraditional college students face unique challenges as they pursue an undergraduate degree. Previous research has shown that nontraditional students withdraw from their undergraduate programs at rates significantly higher than that of traditional college students. This research has suggested that the numerous roles and responsibilities they manage make it difficult to persist in completing an undergraduate degree. Using situated expectancy value theory (SEVT), this phenomenology explored the perceptions of the lived experiences of motivation for pursuing and persisting in completing an undergraduate degree among seven nontraditional college students at a public university in the eastern central region of the United States. …

Process Of Determining Multilevel Performance Indicators To Assess Network Effectiveness: A Qualitative Case Study Of Usaid’S People-To-People Reconciliation Programs, Prapti Sedhain

School of Public Service Theses & Dissertations

Although the literature considers networks as effective mechanisms for resolving complex policy issues and delivering public services, assessing network effectiveness through proper evaluation is necessary to determine whether networks really work (Provan & Milward, 2001). However, evaluating effectiveness in networks is more complicated than in single organizations. Due to the multilevel structure of the network and the involvement of various key stakeholders with multiple and diverse interests, it becomes challenging for network managers and evaluation practitioners to determine relevant performance indicators for evaluation (Provan & Milward, 2001; Babiak, 2009; Herranz, 2019). Despite previous efforts by scholars to address this issue, …

Defining A 'Cells To Society' Research Framework For Appendiceal Tumours, Andreana N Holowatyj, Michael J Overman, Konstantinos I Votanopoulos, Andrew M Lowy, Patrick Wagner, Mary K Washington, Cathy Eng, Wai Chin Foo, Richard M Goldberg, Mojgan Hosseini, Kamran Idrees, Douglas B Johnson, Ardaman Shergill, Erin Ward, Nicholas C Zachos, Deborah Shelton

Faculty, Staff and Student Publications

Tumours of the appendix — a vestigial digestive organ attached to the colon — are rare. Although we estimate that around 3,000 new appendiceal cancer cases are diagnosed annually in the USA, the challenges of accurately diagnosing and identifying this tumour type suggest that this number may underestimate true population incidence. In the current absence of disease-specific screening and diagnostic imaging modalities, or well-established risk factors, the incidental discovery of appendix tumours is often prompted by acute presentations mimicking appendicitis or when the tumour has already spread into the abdominal cavity — wherein the potential misclassification of appendiceal tumours as …

From Flames To Change: An Exploration Of Housing, Fire, And Inequity, Helen Underhill, Charles R. Jennings, Brian Meacham, Danielle Antonellis

Publications and Research

Housing and fire safety are deeply connected: inadequate and poorly maintained housing poses heightened fire risk for occupants. An individual or household’s housing situation (including limited or constrained choice) interacts with issues such as affordability, access, location, quality, safety, occupancy levels, tenure type, and resident or immigration status. These dynamics shape vulnerability, and inequity becomes most visible in the event of a fire. The extreme end of this spectrum includes the unhoused, who occupy structures entirely outside of regulatory systems with little or no fire protection.

Working With Statutes, Anya Bernstein, Cristina Rodriguez

Faculty Scholarship

In its decision overruling the Chevron doctrine—which directed judges to accept an agency’s reasonable interpretation of ambiguous statutory language—the Supreme Court declares: “[A]gencies have no special competence in resolving statutory ambiguities. Courts do.” This Article shows why this statement exhibits a profoundly blinkered judicial hubris. Our interview-based empirical study, involving dozens of agency officials across the administrative state, shows agencies’ special, indeed unique, competence in working with statutes to make democratic enactments real.

Agencies, we show, act as a statute’s custodians, managing the statutory regime over a life cycle that exceeds any single governing coalition. Borrowing ideas from private law, …

Cost-Effectiveness Of Personalized Policies For Implementing Organ-At-Risk Sparing Adaptive Radiation Therapy In Head And Neck Cancer, Seyedmohammadhossein Hosseinian, Daniel Suarez-Aguirre, Cem Dede, Raul Garcia, Lucas Mccullum, Mehdi Hemmati, Aysenur Karagoz, Abdallah S R Mohamed, Stephen Y Lai, Katherine A Hutcheson, Amy C Moreno, Kristy K Brock, Fatemeh Nosrat, Clifton D Fuller, Andrew J Schaefer

Background and purpose: The principle of adaptive radiation therapy (ART) is to adjust radiation plans in response to anatomical changes during treatment. The purpose of this study was to develop a decision-making model for implementation of personalized ART that balances the costs and clinical benefits of radiation plan adaptations in head and neck cancer (HNC).

Materials and methods: Using retrospective imaging data from 52 HNC patients, a Markov decision process (MDP) model was developed to determine optimal timing for plan adaptations based on the difference in normal tissue complication probability (ΔNTCP) between planned and delivered doses to organs-at-risk. To capture …

Insulin-Like Growth Factor 2 As A Driving Force For Exponential Expansion And Differentiation Of The Neonatal Thymus, Seung Woo Kang, Bryan R Helm, Yu Wang, Shiyun Xiao, Wen Zhang, Anusha Vasudev, Ken S Lau, Qi Liu, Ellen R Richie, Laura P Hale, Nancy R Manley

Faculty, Staff and Student Publications

Like all organs, the thymus grows in size and function rapidly during development, but this growth comes to a halt after birth. However, the molecular mechanisms behind such a transition in the thymus remain obscure. Using single-cell RNA sequencing (scRNA-seq) of the murine thymic stroma, we identified that major transcriptomic changes occur in the endothelium and mesenchyme across the transition to homeostasis. Differentially expressed gene and intercellular network analyses of temporally resolved scRNA-seq data revealed fibroblast-derived insulin-like growth factor 2 (IGF2) as a candidate driving neonatal thymic expansion. We demonstrated that IGF2 activity promotes a cortical thymic epithelial cell-specific proliferation …

A New Cure Model Accounting For Longitudinal Data And Flexible Patterns Of Hazard Ratios Over Time, Can Xie, Xuelin Huang, Ruosha Li, Yu Shen, Nicholas J Short, Kapil N Bhalla

Faculty, Staff and Student Publications

With the advancement of medical treatments, many historically incurable diseases have become curable. An accurate estimation of the cure rates is of great interest. When there are no clear biomarker indicators for cure, the estimation of cure rate is intertwined with and influenced by the specification of hazard functions for uncured patients. Consequently, the commonly used proportional hazards (PH) assumption, when violated, may lead to biased cure rate estimation. Meanwhile, longitudinal biomarker measurements for individual patients are usually available. To accommodate non-PH functions and incorporate individual longitudinal biomarker trajectories, we propose a new joint model for cure, survival, and longitudinal …

Gatekeeping Girlhood: Tiktok As An Agent Of Gender And Racial Socialization, Kennedy Elyza Davis

Communication & Theatre Arts Theses

This thesis uses qualitative methods to study and analyze how TikTok users and the platform’s algorithm work together to redefine girlhood. By examining individual posts and the origins of the trends that they belong to, I will show why some users reject this new definition, as others have embraced it, and what this means for the future of girlhood. This research will complicate the question of what it means to be a girl on the Internet and the challenges that accompany this experience. Ultimately, I expand on the study of gender roles and the impact of social media as an …

A Theoretical Framework For Examination Of Context In Complex System Governance, Meggan M. Schoenberg

Engineering Management & Systems Engineering Theses & Dissertations

“A complex system’s identity and viability are directly related and affected by its context. It is important to identify, monitor, and manage (or mitigate risk) system contextual elements” (Keating C. B. et al., 2022, p. 209). Despite this importance, there is very limited research and literature on complex systems context. This research seeks to expand our understanding of complex system context and improve our ability to govern complex technology development programs effectively. The ability to analyze complex systems and their problems is necessary for this improvement.

A “clear understanding of the specific complex system context is fundamental to the process …

Linear Growth During Treatment With A Simplified, Combined Protocol: Secondary Analyses Of Severely Wasted Children 6-59 Months In The Compas Cluster Randomized Controlled Trial, Grace Heymsfield, Kevin Stephenson, Zachary Tausanovitch, André Briend, Marko Kerac, Heather Stobaugh, Jeanette Bailey, Suvi T Kangas

2020-Current year OA Pubs

A simplified, combined protocol treats children with moderate acute malnutrition (MAM), defined by mid-upper arm circumference (MUAC) of <  125 and ≥ 115 mm and no oedema, with 1 daily sachet of ready-to-use therapeutic food (RUTF) and those with severe acute malnutrition (SAM), defined by MUAC <  115 mm and/or oedema, with two daily sachets of RUTF. This protocol was previously shown to result in non-inferior recovery compared to standard treatment that used higher, weight-based RUTF dosing among children with SAM and ready-to-use supplementary food (RUSF) for MAM in a cluster-based randomised controlled trial in Kenya and South Sudan. We conducted a secondary analysis of this trial to compare linear growth among children admitted with MUAC <  115 mm. Linear and ponderal growth were calculated from admission to discharge and visualised using aggregate growth curves. HAZ change adjusted for admission characteristics was negative across the course of treatment but similar across arms [-0.21 ± 0.18 SE in the standard arm, -0.24 ± 0.18 SE in simplified; difference (95% confidence interval) 0.03 (-0.12, 0.18)]. The unadjusted mean ± SE linear growth velocity from admission to discharge was 1.8 ± 0.7 mm/week in the standard arm compared to 1.7 ± 0.7 mm/week in the simplified arm [difference = 0.09 (-0.36, 0.53)] and similar in adjusted analysis. MUAC and weight gain velocities were not significantly different by treatment arm. Reducing the RUTF dose prescribed to children during SAM treatment does not appear to affect linear growth or other growth velocities during treatment.
