Educator Experiences Of Schoolwide Pbis Discipline Implementation: Exploring School Culture In Private Pk–12 Schools, Jessica L. Guarneri

Electronic Theses and Dissertations

The purpose of this phenomenological study was to explore educators’ lived experiences implementing schoolwide Positive Behavioral Interventions and Supports (PBIS) discipline systems and to understand how those experiences influenced school culture in private PK–12 schools. Historically, PBIS focused on specific outcomes, such as reductions in discipline referrals, suspensions, and behavioral incidents. Though these indicators are critical, they do not consider in what way educators experience disciplinary systems, nor how their lived experiences affect routine interactions with students. Educators play a key role in implementing PBIS; their experiences foster consistency, trust, and sustainability. The participants included certified educators and administrators employed …

A Qualitative Examination Of Tennessee Secondary Stem Teachers’ Perceptions On Professional Development Needs, Amber W. Ogle

Electronic Theses and Dissertations

The purpose of this qualitative phenomenological study was to research secondary STEM educators’ perceptions of PD needs. This study focused on the lived experiences of educators actively teaching in STEM subject disciplines in grades nine through 12. The essential question for this research study was: How do Tennessee secondary STEM teachers perceive the relevance, applicability, and impact of PD opportunities? The research was rooted in Knowles’ (1984) theory of adult learning, Andragogy, and Learning Forward’s (2022) Standards for Professional Learning.

Data were collected through 15 semi-structured, one-on-one online interviews. The transcripts of these interviews were analyzed, and frequently used language …

Design Of A Continuum Robot Test Bed Utilizing Model-Free Sliding Mode Control, Joseph Paul Streib

Theses

Continuum robots are a class of continually deformable robots inspired by snakes and tentacles that are commonly used in medical, search and rescue, and exploration applications. The robots are highly nonlinear and difficult to accurately model and control. Precise control of the pose of a continuum robot is typically reliant upon a system model. This work introduces a novel model free control algorithm for continuum robots that only relies upon the robot’s position in task space. The derived controller is built upon the foundation of a preexisting model free sliding mode controller and the q-state parameterized piecewise constant curvature kinematic …

Engineering Materials Function With Reconfigurable Colloids, Laura Galeano Tirado

Theses

The function of a material is defined not only by its chemical composition, but also by the structural organization of its constituents across multiple length scales, from the architecture of individual building blocks to their collective arrangement. Developing strategies to access, engineer, and reconfigure that structure on demand represents a central opportunity in the design of adaptive materials. Here, we present a thermoresponsive polymer-colloid platform that enables high-precision tuning of colloidal structures using only thermal stimuli. Rather than adsorbing to the surface, our polymers diffuse inside organosilica colloids to reshape them from within, allowing continuous modulation of their size, shape, …

Semiconductor Laser Calibration Through Photonic Chip With Microcontroller Driven Wavelength Inference, Clayton Acheson

Theses

Integrated Silicon Photonics leverages light-speed operation with lower power and higher data rates than electronic counterparts. To achieve this, light is sent through a silicon circuit, where it is manipulated to perform various operations. Primarily, the light for these circuits comes from laser sources. Semiconductor lasers are typically used for their small form factor and ability to be heterogeneously integrated into larger, more complex systems. Because the optical phase and wavelength of light respond to minute changes in local refractive index, light is increasingly used for high-sensitivity sensing in integrated photonic circuit applications. As such, schemes that integrate the laser …

Finding Balance: School-Based Yoga Interventions And Their Alignment Within Multi-Tiered Systems Of Support, Ursula Vogt

Educational Specialist, 2020-current

Biology Faculty Publications

Traumatic knee injury leads to posttraumatic osteoarthritis (PTOA) and significant skeletal muscle weakness, resulting in chronic disability. The current standard of care frequently fails to prevent musculoskeletal dysfunction, underscoring the need to identify therapeutic mechanisms of PTOA. Using an established preclinical anterior cruciate ligament (ACL) transection model of PTOA and leveraging an innovative SPiDER-senescence-associated β-galactosidase stain to discern senescent cells, we investigated cellular senescence at single-cell resolution and identified anti-inflammatory macrophages as a predominant contributor to the senescent cell burden in both muscle and knee joint after injury. Clearance of senescent cells using the senolytic dasatinib and quercetin (D + …

The True Scope Of Trusting Your Gut: A Study Into The Enteric Nervous System And The Relationship Between The Gut-Brain Axis And The Mind, Bryan Pham

Theses & ETDs

Since the early days of medicine, the “gut” had been associated as a seat of emotions and intuition, but as modern science marched forward, the brain itself was given complete dominion over mental health. But thanks to research into the enteric nervous system (ENS), which innervates the digestive tract and bilaterally communicates with the brain as a secondary function, we now know that, in a sense, the gut does indeed have a substantial impact on mental health outside of its primary functions. This profound discovery could potentially cause a massive rewrite for decades of modern neuroscience-based medicine. Overall, the study …

Molecular Refinement Of The Taxonomy Of Pyrgulopsis Springsnails In Western North America, Michael K. Young, Kristine L. Pilgrim, Eric S. Miskow, Chante L. Lundskog, Kathryn E. Perez, Michael K. Schwartz

School of Integrative Biological & Chemical Sciences Faculty Publications

Springsnails in the genus Pyrgulopsis in western North America have long been a dilemma for taxonomists. Defining species boundaries has been complicated by the presence of undiscovered or cryptic taxa, range over- or underestimation, species complexes representing an unknown number of species, and named species synonymous with other taxa. To address these issues, we conducted an array of molecular species delimitation analyses using sequences from up to 2 mitochondrial and 2 nuclear genes from over 5000 specimens representing 140 of the 151 currently recognized taxa. These analyses reaffirmed most species hypotheses, favored synonymy for some taxa and redrawing of species …

Predictors Of The Mother-Infant Bond: The Role Of Maternal Attachment Style, Parity, Race, And Motherhood Expectations, Samia Qadri

Theses, Dissertations and Culminating Projects

This study examined how maternal attachment style, parity, race, and motherhood expectations, individually and in interaction, predicted the quality of the mother-infant bond during the postpartum period. Grounded in a maternal feminist framework, the study used a quantitative, cross-sectional correlational design. Postpartum mothers aged 20–39 (N = 87) completed validated measures of maternal attachment style, motherhood expectations, mother-infant bonding, and depressive symptoms. Multiple regression compared a Primary Model containing the four focal predictors and planned interaction terms with a Secondary Model that added maternal depressive symptoms as a covariate. Depressive symptoms emerged as the strongest single predictor of bonding, and …

Validating The Expression Of Genes Potentially Involved In The Development Of Aggressive Melanoma Tumor In The Zebrafish Melanoma Model, Mayra Matos Diaz

Theses, Dissertations and Culminating Projects

Melanoma is an aggressive form of skin cancer characterized by rapid progression, metastatic potential, and the frequent development of resistance to targeted therapies. Although the Inducible cAMP Early Repressor (ICER) has been identified as a potential tumor suppressor in melanoma, the molecular mechanisms underlying its role in tumor progression remain poorly understood. Building upon the transcriptomic findings of Wheelan et al. (2025), this study investigates the relationship between ICER and ten candidate genes (gdf6a, pdgfra, col4a4, fgfr2, pdgfrb, cdkn1a, fgf5, akt1, met, and notch3) associated with BMP signaling. Quantitative polymerase chain reaction (qPCR) was used to compare gene expression between …

Temperature And Salinity Effects On The Physiology Of Bullfrog Tadpoles (Lithobates Catesbeianus) From A Suburban Temperate Wetland, Angela Brown

Theses, Dissertations and Culminating Projects

One of the most robust amphibians is the American Bullfrog, Lithobates catesbeianus, which is a widespread species that is invasive worldwide, and is broadly tolerant of a range of environmental conditions. Despite this tolerance, survival and performance of adult L. catesbeianus can be negatively affected by increasing temperatures and salinity resulting from anthropogenic impacts, such as climate change and road salts. This study focuses on the effects of acute salinity exposure (mimicking road salt influx into a pond) on L. catesbeianus tadpoles at different larval stages. Increased salinity was predicted to negatively affect two physiological performance measures. Critical maximum temperature …

Education Theses and Dissertations

This Improvement Science Dissertation in Practice concentrated on the persistent problem of freshman course failure at a large, diverse, Title I high school serving a military-connected community in Central Texas. Although intervention programs existed, an increasing number of ninth-grade students were consistently failing one or more courses during their first year of high school, which revealed several gaps in the campus’s system of support. The Improvement Science framework and two Plan-Do-Study-Act (PDSA) cycles were used to examine the factors contributing to freshman course failure and to assess the interventions implemented to improve academic success as students transitioned into high school. …

Evaluating The Discus Throw As An Ancient Greek Combat Training Tool Through Modern Performance Metrics, Daniel R. Porter

All Graduate Reports and Creative Projects, Fall 2023 to Present

This study’s purpose was to explore the correlations between peak velocity in a rotational throw with a medicine ball, peak force (PF) and rate of force development (RFD) in an isometric mid-thigh pull, time to failure in a plank test, and peak velocity in a sword thrust task, which was also tested for reliability. Twenty-seven recreationally trained male participants between the ages of 18-35 completed the study. The sword thrust task was significantly correlated with the medicine ball throw (p = 0.012, r = 0.475, r² = 0.226, 95% CI [0.724, 0.116]) and PF (p = 0.045, r …

Economic Efficiency Of End-Guns On Center Pivot Irrigation Systems For Utah Alfalfa Production, Sophia Moss

All Graduate Reports and Creative Projects, Fall 2023 to Present

This study looks at whether using an end-gun on a center pivot irrigation system is financially worthwhile for Utah alfalfa producers. End-guns are used to water extra acreage beyond the end of a pivot, they can also apply water less evenly, which may reduce production on those outer acres. To examine this tradeoff, the study compares farm returns with and without an end-gun using historical Utah alfalfa price and yield data along with estimates of irrigation cost, added acreage, and possible yield loss. The results suggest that end-guns can improve profitability in many cases, mainly because they bring more acres …

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 …

Temporal Legitimacy And Civilizational Logic: A Sociological Perspective On The Foundational Principles Of Chinese Civilization, Yuk Man Cheung

Comparative Civilizations Review

This article departs from the recent social-scientific analytical framework for comparative civilizations proposed by the sociologist Liah Greenfeld (2024a, 2024b, 2025) and puts forward several basic conjectures regarding the analysis of the characteristics of Chinese civilization, with the aim of assisting our understanding, execution, and integration of empirical studies. Precisely because these are conjectures, they differ from conventional academic research–especially the case-study-oriented research style dominant in contemporary Anglophone academia. Accordingly, this article can only be regarded as an attempt that, starting from sociological theory, offers preliminary conjectures and tentatively constructs a theoretical framework within which specialists from different fields may …

The Concept Of A ‘State-Civilization’ In Russia: The Contest For National Dignity In The Form Of A Civilizational Analysis, Ivan Nokhrin

Comparative Civilizations Review

This article examines the contemporary Russian concept of the “state-civilization” as articulated in official discourse, educational materials, and nationalist thought. It argues that the notion of Russian civilization functions primarily as a symbol of national dignity and exceptionalism rather than an analytically coherent concept. Through analyzing narratives surrounding traditional values, state-centrism, family, and patriotism, the study demonstrates that these themes largely reproduce longstanding patterns of Russian nationalism and its opposition to the West. Drawing on Greenfeld’s theory of civilization, the article contends that Russia is best understood as part of the broader monotheistic civilization rather than a distinct civilization of …

The Family As A Mechanism Of Civilizational Continuity: Absorption, Localization, And Rejection Of Modern Values In The Indic Case, Monika Monika

Comparative Civilizations Review

Contrary to the common view that the family socializes the individual into a given culture, this paper insists that the family performs a far more profound, indeed, a constitutive function. It is not simply the first school of civilizational values; it is the primary institutional site through which a civilization reproduces its symbolic order and, in so doing, acts as the gatekeeper of civilizational continuity and change. It is here that a civilization’s foundational principles are first internalized; and it is here, too, that modern values, or new norms thrust upon it by encounters with alien civilizations ⎯ are first …

Liah Greenfeld And Civilizational Dialogue: For Continuing A Legacy, Manindra Nath Thakur

Comparative Civilizations Review

One fine morning, I dropped into my room at the Centre for Political Studies, JNU. Monika took an appointment to meet and discuss her project. I was curious to know about her work and wanted to see if there was anything to learn from it. Within no time, I discovered that she was influenced by a professor and that we had many common concerns. I listened carefully and was convinced by her impression. We decided to initiate a conversation. Suddenly, a few months later, she informed me about Liah Greenfeld’s sad demise. Our conversation could not take off.
