The Effects Of Varying Temperatures And Food Availability On The Reproductive Output Of The Acorn Barnacle: Chthamalus Fissus, Karina L. Rog

McNair Summer Research Program

Climate change is predicted to intensify ocean warming and the reduction in phytoplankton abundance, potentially disrupting reproductive processes in filter-feeding intertidal invertebrates. This study investigated the combined effects of water temperature increases and food availability on the reproductive output on Chthamalus fissus, a dominant intertidal barnacle species found along the Southern California coastline. Using a controlled laboratory experiment, adult barnacles collected from the nearshore rocky intertidal habitat in La Jolla, California, were exposed to two temperature regimes (ambient water temperature ~ 18°C and elevated water temperature ~ 20-21°C) and two food concentration treatments (low and high phytoplankton and rotifer …

Topological Homotopy Groups, Tyler Evans

Theses and Dissertations

In general, the homotopy groups of topological spaces fail to be topological groups when endowed with the quotient topology. In this thesis, we show that for Peano continua with Abelian fundamental group, the fundamental group endowed with the quotient topology is indeed a topological group. However, this result does not extend to higher homotopy groups; that is, there exists a Peano continuum whose nth homotopy group, endowed with the quotient topology, is not a topological group. Additionally, a new characterization of the quotient topology in terms of a limit operator is introduced.

Under What Conditions? A University Pathway Program Evaluation, Michael Burke

Electronic Theses and Dissertations

As U.S. universities face a declining domestic applicant pool, commonly referred to as the “enrollment cliff,” international student recruitment provides a practical strategy for offsetting domestic enrollment shortfalls. One such strategy for increasing international student enrollment is through the establishment of university pathway programs that grant conditional admission to international applicants who fail to meet English language proficiency requirements but are otherwise academically admissible. As a baseline program evaluation, this study utilized a quantitative methods approach employing logistical regression analysis to determine if incoming standardized English language proficiency test scores, English as a Second Language (ESL) course GPA, and student …

Adding Varying Degrees Of Performance Feedback Components To The Taped Problems Intervention, Alyson C. Honaker

Electronic Theses and Dissertations

Math fact fluency, the ability to quickly and accurately solve one-digit by one-digit math problems, is a common challenge for many school-aged children. Difficulties with fluency often lead to reliance on inefficient strategies, hindering progress in more advanced math skills. Evidence-based interventions like Taped Problems Intervention (TPI) have demonstrated effectiveness in improving math fluency. However, research suggests incorporating behavioral components such as Performance feedback (PF) and goal setting/reinforcement (GS/R) may enhance its effectiveness. The present study used a multiple-probe across-task design to evaluate the effects of three variations of TPI on the subtraction fluency of five elementary students in a …

The Application Of Macrophage-Targeted, Anti-Inflammatory Celecoxib Nanoemulgel For Nerve Regeneration In Peripheral Nerve Injury, Lu Liu

Electronic Theses and Dissertations

Peripheral nerve injury (PNI) refers to damage to the nerve located outside the brain and spinal cord. PNI is commonly caused by a physical accident (trauma) or medical operation^{1, 2}. The impact on the quality of life of PNI patients is directly correlated to neuropathic pain, resultant depression, and increased stress². Even after recovering from the PNI, patients still experience phantom pain and lose the ability to work due to the loss of tactile sensory or motor function^2-4. However, unlike damage to the central nervous system (CNS), peripheral nerves can regenerate because macrophages clean …

Promoting Inclusion Through Evidence-Based Behavior Management: Effective Interventions For Students With Asd In General Education, Emma Kaiser

Masters Projects

As diagnoses of autism spectrum disorder (ASD) continue to rise, general education classrooms are increasingly responsible for meeting the needs of students with ASD. However, many teachers lack the training and resources necessary to manage challenging behaviors effectively. This knowledge gap often results in exclusionary practices such as restraint, seclusion, and suspension, which act as barriers to inclusion. The purpose of this project is to equip educators with evidence-based behavior management strategies that support inclusive practices. Drawing from current research, the project organizes effective interventions into three key categories: preventing challenging behaviors, teaching alternative skills, and reinforcing positive behaviors. Each …

Assessing Greenhouse Gas Emissions From Michigan’S Drowned River Mouths Using In Situ And Remote Sensing Methods, Jillian A. Greene

Masters Theses

Freshwater estuaries are natural contributors to the carbon cycle including production and emission of methane (CH4) and carbon dioxide (CO2), potent greenhouse gases (GHGs); however, estimates of their contribution to regional and global GHG emissions is largely unconstrained. Few studies have examined the quantification and drivers of lake CH4 and CO2 production in the Great Lakes region and how it may differ in response to anthropogenic development. In this study, CH4 and CO2 emissions were measured from three drowned river mouth estuaries (DRMs) along the eastern shore of Lake Michigan in 2024. The DRMs exist along a latitudinal gradient ranging …

Development Of Numerical Tools And Performance Metrics For Analysis Of Optical Particle Counters, Doug Webb

Theses and Dissertations

Monitoring air quality is essential for understanding and mitigating the health impacts of airborne particulate matter (PM), which is linked to respiratory and cardiovascular disease. Optical particle counters (OPCs) are widely used for air quality monitoring, yet their precision and accuracy remain uncertain due to inconsistent performance evaluations. In this thesis, performance metrics are developed that can be used to assess the accuracy of OPCs in measuring PM concentrations and size distributions. Computational fluid dynamics (CFD) simulations are employed to analyze the behavior of particle-laden air streams through representative OPC models. The impact of design parameters is quantified using newly …

Teacher Challenges In Ela Instruction For Low-Achieving Elementary Students In Urban Title I Schools, Keshiea Tamika Chandler

Walden Dissertations and Doctoral Studies

The problem that was addressed through this study is that approximately 80% of upper elementary students do not reach proficiency in English Language Arts (ELA) at an urban Title I school district in Georgia, despite implementing intervention and literacy programs. Guided by Senge’s organizational learning theory and Vygotsky’s sociocultural theory, the purpose of this qualitative study was to investigate the challenges that elementary teachers face when providing ELA instruction to low-achieving students in a local Title I school district in Georgia. For this basic qualitative design, semistructured interviews were conducted with 12 ELA teachers across Grades 3-5. Data were analyzed …

From Age Estimation To Age-Invariant Face Recognition: Generalized Age Feature Extraction Using Order-Enhanced Contrastive Learning, Haoyi Wang, Victor Sanchez, Chang Tsun Li, Nathan Clarke

School of Engineering, Computing and Mathematics

Generalized age feature extraction is crucial for age-related facial analysis tasks, such as age estimation and age-invariant face recognition (AIFR). Despite the recent successes of models in homogeneous-dataset experiments, their performance drops significantly in cross-dataset evaluations. Most of these models fail to extract generalized age features as they only attempt to map extracted features with training age labels directly without explicitly modeling the natural ordinal progression of aging. In this paper, we propose Order-Enhanced Contrastive Learning (OrdCon), a novel contrastive learning framework designed explicitly for ordinal attributes like age. Specifically, to extract generalized features, OrdCon aligns the direction vector of …

Effect Of Histidine Tag On The Enzymatic Activity Of Pseudolysin And Its Interaction With The Streptomyces Metalloprotease Inhibitor (Smpi) Protein, Adewale Adeboye Adewole

Electronic Theses and Dissertations

Pseudolysin (PLN) protein is a major virulent factor in Pseudomonas aeruginosa infection. PLN belongs to the family of zinc-dependent metalloproteases. It is naturally inhibited by a smaller protein called streptomyces metalloprotease inhibitor (SMPI), secreted by Streptomyces nigrescens. Previous and current studies demonstrate that the interaction between PLN and SMPI offers unique mechanistic insights for drug development against infections caused by P. aeruginosa. This study investigated the effect of N-terminal Histidine (His) tag on the enzymatic activity of PLN and its interaction with SMPI. His-tagged PLN and SMPI proteins were expressed in bacteria and purified by affinity chromatography …

Wavelet Representation Of Singular Integral Operators, Jeremy Cummings

Arts & Sciences Graduate Student Theses and Dissertations

The idea of representing singular integral operators as averages dyadic shifts has proven fruitful since Petermichl's representation of the Hilbert transform, and its generalization by Hyt\"onen to prove the $A_2$ conjecture. These results employ a random dyadic decomposition of the operator in terms of Haar shifts of all complexities. An alternate approach to wavelet representation was provided by Di Plinio, Wick, and Williams (2022) in which the random dyadic grids are replaced by zero-complexity wavelet projections, providing finer control of smooth operators and a more efficiently computable representation. The goal of this thesis is to provide two main generalizations of …

School of Earth, Environmental, & Marine Sciences Faculty Publications

Hydroponic nutrient solution (HNS) has been established as an ideal conduit for pathogen contamination and proliferation. This study evaluated the efficacy of lactic acid bacteria and their metabolites in mitigating the risk of foodborne pathogens in HNS when compared to conventional chemical treatments. Hoagland’s HNS were prepared according to the manufacturer’s instructions and inoculated with Salmonella Typhimurium, Escherichia coli 0157:H7, and Listeria innocua at 105 CFU/mL cell concentration. These nutrient solutions were subjected to treatment with various concentrations of Lactobacillus rhamnosus live cells, a cell-free extract (CFE) of L. rhamnosus metabolites, sodium hypochlorite and peroxyacetic acid at 22 ± 1 …

Streamlining The Cleaning And Analysis Of Eye Tracking Data For Cross-Recurrence Analysis, Michael V. Rosalia

McNair Summer Research Program

The use of multimodal data to understand and support collaborative learning has grown in popularity recently as it allows researchers to study complex learning tasks from different facets. However, multimodal analysis is often computationally complex and often requires a strong set of technical skills and mathematical understanding to clean and process the data, creating barriers that restrict researchers without advanced programming skills from conducting these analyses. There are existing software packages that can help with this process, but they are often piecemeal requiring the user to understand how to put them together and what best practices may entail. This can …

The research location is focused on erosion-prone areas. The research consisted of a soil resource inventory and a vegetative conservation application. The vegetative conservation application method used a Randomized Block Design (RBD) pattern, composed of 2 factors. The first factor is mulching, namely: no mulching (M0) and mulching (M1), …

Meet The Fars: An Examination Of The Background, Roles, And Appointment Of Faculty Athletic Representatives At National Collegiate Athletic Association Member Institutions, Chris Corr, Christopher Atwater, Mark S. Nagel, Richard Southall, Rick Eckstein, Marek Taškár

Journal of Issues in Intercollegiate Athletics

As many National Collegiate Athletic Association (NCAA) member institutions continue to engage in athletic centric decision-making processes, academic integrity and the campus experience for college athletes is often marginalized. Mandated by the NCAA to represent athletes’ academic interests, the faculty athletics representative (FAR) position is designed to occupy a central role in maintaining the primacy of academia among college athletes. FARs, however, exist within an institutional setting muddled by competing and contradictory logics. Accordingly, given the inherent juxtaposition between the operation of collegiate athletics and the stated role of FARs, the present study sought to examine the characteristics and positional …

Journal of Educational Research and Practice

Significant equity gaps in introductory STEM courses create barriers in the STEM pathway. The current study investigated the impact of equitable access to course resources in the form of different e-textbooks in an introductory chemistry course. The purpose of the study was to determine if the use of a free textbook and/or the use of an interactive textbook enhances students’ academic performance, especially among students from marginalized backgrounds. We analyzed equity data for 199 general chemistry students. Overall, the pattern of course equity gaps suggests there was a positive impact of implementing a free textbook on students’ grades, with the …

The Distribution Of Some Soil Arthropods In A Manipulated Ecosystem, James H. Shaddy, James W. Butcher

The Great Lakes Entomologist

[Excerpt] Soil cultivation practices and agricultural utilization affect soil animal populations in various ways. Gisin (1955) and Schalk (1968) concluded that the effect was minimal. Others observed a deleterious effect (Karg, 1956; Sheals, 1956; Strebel, 1957; Aleinikova and Utrobina, 1975; Edwards and Lofty, 1975). However, some soil animals appear to be benefited (Aleinikova and Utrobina, 1975; Edwards and Lofty, 1975). The effects of cultivation and many other factors have been discussed thoroughly in reviews by Christiansen (1964), Burges and Raw (1967), Butcher, et al. (1971), Ghilarov (1975), and Wallwork (1976).

Orbital Evolution Of The Datura Asteroid Family, Skylar G. Butler

Beyond: Undergraduate Research Journal

To research the Datura Family of asteroids, we used an orbital evolution code to track the orbital decay of asteroid fragments released in an asteroid disruption. Different particle sizes of 10, 100, 500, 750, and 100 micrometers were tracked including the semi-major axis, eccentricity, and inclination in order to observe how certain particle sizes’ orbital elements evolve. Using a young asteroid family like the Datura family gives more insight into the parent asteroid structure and formation because the time is closer to before the asteroid’s breakup. We use these models to constrain the parameters of the dust by comparing the …

Non-Linear Atom-Laser Interactions Using Rubidium Pump-Probe Spectroscopy, Grace Neil

Beyond: Undergraduate Research Journal

An experiment was performed to demonstrate the pump-probe spectroscopy of Rubidium (Rb) vapor, revealing the nonlinear atom-laser interactions in the 5S1/2 ↔ 5D5/2 transition in Rb that can be used to generate quantum entanglement between two laser beams. The setup included a tunable infrared diode laser, optical mirrors, photodiode-detectors, a beam-splitter, and a temperature- regulated rubidium gas chamber, all of which are controlled by the TeachSpin laser controller and monitor. The output from the laser-diode was split into a pump (90%) and a signal probe (10%), which intersected in counter-propagating directions inside the Rubidium chamber. The analysis shows that in …
