A Dual-Emission Polymer-Dots/Gold-Nanoclusters Nanohybrid For Ratiometric Fluorescence Detection Of Hg²⁺, Sha Wu

Dissertations and Theses

Heavy metals, such as Hg, Cd, Pb, and Cr, become a serious environmental problem because they are highly toxic, bioaccumulation, and long-term persistence, required a high sensitivity and selectivity detection method. Although laboratory testing instruments, such as inductively coupled plasma mass spectrometry, offer high sensitivity, their practical application is limited because they rely on large-scale equipment and complex sample pre-treatment processes. Single-emission fluorescence probes are simpler but can be affected by variations in probe concentration, excitation intensity, and measurement conditions. In this study, a dual-emission nanohybrid that consists of poly(9,9-di-n-hexylfluorenyl-2,7-diyl) (PDHF) and bovine serum albumin (BSA), termed as PDHF-Pdots/BSA-AuNCs nanohybrid, …

Despite these advances, the field remains fragmented, with limited integration between nanomaterial design, biomarker selection, and data-driven analysis, and persistent challenges related to reproducibility, standardization, and clinical validation. …

Image-Derived 3d Hepatic Lobule Modeling Of Acetaminophen-Induced Hepatotoxicity, Rebecca Lauren Strauss

Selected Full-Text Master Theses 2021-

The liver’s highly structured vascular microarchitecture governs blood perfusion, metabolic zonation, and the spatial distribution of xenobiotic toxicity. Current computational models of hepatic drug metabolism often oversimplify this geometry, limiting their ability to capture realistic flow dynamics and cellular injury patterns. This study develops a multiscale computational framework to predict acetaminophen-induced hepatotoxicity using image-derived, three-dimensional hepatic lobule geometries. The model integrates computational fluid dynamics (CFD) with a mechanistic cellular injury module to simulate the interplay between perfusion, metabolism, and hepatocellular viability.

Realistic vascular reconstruction was achieved from histopathology liver slices, and the resulting geometry was meshed and solved using ANSYS …

Deep Learning For Eeg-Based Emotion Recognition With Temporal And Spectral Interpretability, Shruti Rameshbhai Shingala

Selected Full-Text Master Theses 2021-

Electroencephalography (EEG)-based emotion recognition has emerged as a critical component of affective computing and clinical neuroscience. Existing approaches to this problem primarily reduce the multi-dimensional EEG time series to a single averaged feature vector, thereby discarding the temporal structure of the emotional response. The present work addresses three identified gaps in the literature: the absence of temporal interpretability, the uniform use of frequency bands, and the use of single-scale temporal feature extraction. A deep learning architecture, MST-Mamba-Asym, is proposed, comprising four components: Asymmetry Attention, which encodes hemispheric asymmetry by computing signed left–right channel differences, FreqBandAttention, which learns differential weights across …

Gender, And Socioeconomic Status In School-Based Speech-Language Pathology Decision-Making For Adolescents With Traumatic Brain Injury: A Critically Appraised Topic, Geneva Renee Toledo

Selected Full-Text Master Theses 2021-

Purpose: Adolescents are at greater risk for traumatic brain injury (TBI), and TBI-related symptoms may contribute to disciplinary actions that increase their risk of entering the school-toconfinement pipeline. Given the disproportionate representation of racially marginalized male adolescents within this pipeline, this critically appraised topic (CAT) examined how race, gender, and socioeconomic status may influence school-based speech-language pathology (SLP) services and clinical decision-making following TBI. Method: A structured search of five electronic databases was conducted to identify studies examining speech-language pathologists’ (SLPs’) clinical decision-making and management of adolescents with TBI in relation to race, gender, and socioeconomic status. Relevant studies were …

Helpful Autism School-Based Services: Perspectives From The People That Received Services, Michael Angelo Grizzaffi

Dissertations and Theses

Transitioning high school students with autism, primarily with a level 1 diagnosis, from high school to independence in young adulthood has evidence-based practices. However, preferences of the students who are receiving services had not been considered before. This study reviews the thoughts of what prior high school students find helpful in the services they receive. Choosing individualized evidence-based practices is ideal for students. Prior high school students' experiences demonstrate the desire for more transition skills teaching. Leading special educators in the skills of some evidence-based practices is required for the individualization of these practices the students need to occur. Leading …

Large Language Model Communication And Data Transfer Across A Simulated Telephone Line, Jared Reyes

Dissertations and Theses

This thesis presents a proof-of-concept communication system in which two local large language model endpoints communicate across a simulated analog telephone line using legacy USB modems. The project combines modem voice mode, modem data mode, local speech processing, and structured machine messaging into a single staged session. During the voice phase, one endpoint places a call, the other answers, speech generated by a locally hosted LLaMA-family model is synthesized with Piper, transmitted through the modem voice path, captured on the remote side, and transcribed with Faster-Whisper to drive the next response. After the voice exchange, the system transitions to a …

Evaluating Motivation In Stem Education: A Positive Self-Talk Intervention, Tiffany L. Copeland

PCOM Psychology Dissertations

This study evaluated a social-emotional learning intervention that taught positive self-talk to high school students from underrepresented minority groups in science, technology, engineering, and math (STEM). The setting of this study was a place-based program that immersed students in hands-on STEM activities while located in Philadelphia’s life science hub. Before taking a science assessment, students set effort-based goals and learned to say self-talk statements such as “I will give my best effort” and “Even when it's hard, I will give 100%.” This mixed-methods program evaluation compared pre- and post-intervention data using a paired-samples t-test, linear regression, and correlation analyses. Data …

In Search Of Mozart: A History And Analysis Of The Pianos He Knew And Wrote For, Adele Benoit

Dissertations and Theses

The better one can understand what influenced and inspired a composer, the more informed and authentic one’s understanding and performance of that composer’s music will be. The musical world which influenced Mozart was a vastly different one from the musical world of the twenty-first century, and the pianos which Mozart was inspired by and wrote for were designed according to entirely different musical ideals than those according to which the modern piano was created. In order to understand the piano music of Mozart, it is important first to understand not only the musical world in which he wrote and the …

The Efficaciousness Of Generative Ai For Integrated Stem Planning And Its Impact On Stem Teacher Self-Efficacy, Julie Ann Olson

Dissertations and Theses

With evolving workforce needs, global challenges, and national science education initiatives calling for STEM instruction with purposeful connections between the four domains, there is a need for methods to support educators facing the challenges this pedagogical approach presents. Challenges may weaken teachers' self-efficacy, potentially reducing the probability that an integrated STEM (I-STEM) pedagogy would be sustained in the classroom. There is limited research addressing how generative artificial intelligence (GAI) has been used for I-STEM lesson development, combined with its effects on I-STEM teaching self-efficacy (SE) grounded in social cognitive theory. This study investigated how GAI influences I-STEM teaching SE, when …

PREPARING STUDENTS FOR WHAT COMES NEXT: A QUALITATIVE STUDY OF DISTRICT APPROACHES TO POSTSECONDARY AND CAREER READINESS

This qualitative study examines how Illinois school districts support students’ readiness for postsecondary success and career planning and exploration. Despite longstanding state and federal efforts to improve college and career readiness, many students continue to face challenges after high school, including lack of workforce readiness, underpreparedness for postsecondary education, unclear career pathways, and difficulty navigating complex transitions. Using semi-structured interviews, this study explores how districts conceptualize and implement career readiness frameworks, the ways readiness work is embedded within district systems, and the barriers …

What Do They Expect? Understanding Preservice Teachers' Views On A Social Studies Teaching Methodology Course, Jeanine A. Clark Bremer

Dissertations of Practice

This dissertation examined preservice teachers’ expectations of their social studies methods course. Methods courses serve as a transition point helping preservice teachers to take content knowledge and learn how to use it as an educator. Social studies methods was selected due to its unique position in elementary education. It is a subject area that is no longer a core subject. Despite that, teachers are still expected to provide students with the content knowledge. The expectations matter because of how they influence preservice teachers’ approaches to the course.

As a phenomenological case study, qualitative methods were employed to better understand how …

Rethinking Climate Change Education: Wyoming And New Jersey As Effective Models Of Climate Change In Education Standards, Jamie W. Miller

Pitzer Senior Theses

Education is an essential and oft-overlooked part of the conversation about climate change. As I’ll demonstrate in this thesis, education shapes how the public understands climate change and creates environmental knowledge, attitudes, behaviors, and intentions. Exploring and understanding climate change education allows us to understand how people form perspectives about climate issues. This topic is extremely important, but one we often gloss over when thinking about climate solutions. I analyzed three case studies of educational standards in the United States to understand how political context, writing focuses, and benchmarks impact the efficacy of climate change standards. My research found that …

Coupling Liquid Chromatography To Orbitrap Isotope Ratio Mass Spectrometry: Overcoming Isotope Effects Of Chromatography And Amount-Dependency By Peak Homogenization, Aoife Canavan, Leonhard Prechtl, Habib Al-Ghoul, Nils Kuhlbusch, Andrea M. Erhardt, Martin Elsner

Earth and Environmental Sciences Faculty Publications

Electrospray ionization Orbitrap mass spectrometry (ESI-Orbitrap-MS) has recently proven to be a powerful tool for compound- and position-specific stable isotope analysis, targeting isotopologues of multiple elements (H, C, N, O, S) in polar analytes. However, studies have so far mainly focused on pure analyte solutions via direct infusion. Here, we present the online coupling of liquid chromatography (LC) to ESI-Orbitrap-MS for stable isotope analysis of sulfamethoxazole (SMX), a synthetic antimicrobial, used as a model compound. Our study explored the fidelity of isotope values with two strategies for capturing and broadening chromatographic peaks after LC. When capturing the target analyte in …

Geoscience Mathematics Self-Efficacy Scale (Geomses) For Majors-Level Undergraduates: Psychometric Data, Michael Coe, Rory Mcfadden, Beth Pratt-Sitaula, Eric Baer

Science Education Resource Center (SERC)

Self-efficacy is often investigated as a key attitudinal component of academic persistence and performance, and self-efficacy surveys can serve in research models as efficient and non-threatening assessment tools to augment or substitute for achievement or performance measures. The Geoscience Mathematics Self-Efficacy Scale (GeoMSES) builds on prior work in measurement of self-efficacy for mathematics by focusing specifically on students’ capacity to apply mathematical skills to typical problems encountered in majors-level undergraduate geoscience courses or in professional geoscience settings. The scale was developed as part of program evaluation research for a set of learning modules designed to augment existing geoscience curricula. In …

One Decade, One Map: State Constitutional Limits On Re-Redistricting, Joshua A. Douglas

Minnesota Law Review Vols. 106:2 onward (2021-present)

In 2019, the U.S. Supreme Court closed the federal courthouse doors to claims of partisan gerrymandering, effectively permitting states to engage in what it called “constitutional political gerrymandering.” A few years later, several states embraced this invitation, redrawing maps mid-decade for openly partisan ends. State courts must now confront a different and more basic question than in a typical partisan gerrymandering case: When a state engages in re-redistricting, is pure partisanship allowable under the state constitution?

This Essay argues that, in these situations, state courts should adopt a presumption of unlawful partisanship under state constitutions. Virtually all state constitutions say …

Between “The Favela” And “The City”: Exploring The Daily Geographies Of Carolina Maria De Jesus Using Gis, Sterling D. Quinn

Geography Faculty Scholarship

Geographic information systems (GIS) enable interesting visual and analytical engagement with personal narratives. I offer a case study by constructing digital historical maps of Carolina Maria de Jesus’s São Paulo as described in her 1950s diary entries from Quarto de Despejo (published as Child of the Dark in English). Examining 48 locations mentioned in the book, I show how GIS algorithms such as standard deviation ellipses and kernel density estimation can summarize geographies of daily activities in the personal, institutional, and professional realms, including in the informal economy. I also employ ideas from feminist cartography to put Carolina’s own words …

Toward Conditions For Consensus Of Noisy Bounded-Confidence Models, Madeline Reeve

HMC Senior Theses

Models of opinion dynamics aim to describe the spread of opinions over time in a social network. However, many canonical models are deterministic and thus may fail to capture uncertainty present in social interactions. This work investigates the effect of adding noise into bounded-confidence models, a class of opinion dynamics models where agents are more likely to be influenced by opinions close to their own. In particular, we propose a noisy modification of the Deffuant–Weisbuch bounded-confidence model. We prove that in this model all agents eventually adopt the same opinion—that is, our model converges to consensus. In doing so, we …

Understanding Space Frontier Areas: Strategy In Cislunar Space And Beyond, Todd W. Pennington

INSS Strategic Perspectives

Space beyond geostationary Earth orbit, particularly cislunar space, is emerging as a strategically significant domain for national security, governance, and long-term competition. This paper introduces the concept of "Space Frontier Areas" to describe regions of space, including xGEO and the Earth–Moon system, where operations remain limited in scale but increasingly consequential. It argues that current strategic thinking about these areas is overly bipolar, framing activities as either near-term security concerns or long-term economic opportunities, thereby constraining nuanced policy choices. To address this limitation, the paper proposes an analytical framework organized around four strategic purposes—prestige, governance, security, and resources—that can be …

The Presence Of Predators Moderates Evolutionary Responses Of Trinidadian Killifish To A Novel Parasite, Anne E. Christian

Biology Dissertations

The Healthy Herds Hypothesis suggests the idea that prey populations derive a benefit from their predators: predators reduce the exposure of their prey to infectious disease, both by limiting prey population densities and by eliminating sick individuals. Much research has focused on the balancing effect that predators have on ecosystems. There is a current need for research into whether these effects cause evolutionary shifts in prey populations, where strong predation pressure prevents prey species from evolving physiological tolerance or resistance to infectious agents. Parasites especially often have rapid effects on host evolution, due to exploitative interactions.

I seek to address …
