“I Call For The Resurgence And Reclamation Of Our Indigenous Ways”: Institutional Landscapes, Resistance, And The Experiences Of Mmir Advocates, Sara Tehrani

Graduate Studies Theses and Dissertations 2026

Indigenous Peoples across Turtle Island experience disproportionately high rates of violence and homicide compared to other racial groups. Rooted in coloniality and sustained by Western institutions, this epidemic is recognized as the Missing and Murdered Indigenous Relatives (MMIR) crisis. In response, Indigenous women have mobilized the MMIR Movement to raise awareness and advocate for institutional change. Although scholarship on MMIR has expanded, limited research has explored the experiences of MMIR advocates. This study interrogates the institutional landscapes that shape MMIR advocacy and explores the resistance strategies advocates employ to address the crisis. Using reflexive thematic analysis, this study examines semi-structured …

M-Type Star Spectral Analysis: Sco Line List Including The B²Σ⁺-X²Σ⁺ Band System, Léo Lavy, Jacques Liévin, Peter F. Bernath

Chemistry & Biochemistry Faculty Publications

An analysis of the B²Σ⁺ − X²Σ⁺ band system of ⁴⁵Sc¹⁶O is presented. ScO was excited in a hollow cathode discharge, and its Doppler-limited resolution spectrum was measured with a Fourier transform spectrometer. The spectroscopic constants of the B²Σ⁺ state with v ≤ 3 are reported, and equilibrium constants are derived. Ab initio transition dipole moment functions are calculated for the A²Π − X²Σ⁺ and B²Σ⁺ − X²Σ⁺ transitions and scaled using lifetime measurements. We report new line lists of hyperfine-resolved transitions for ⁴⁵Sc¹⁶O with recalculated Einstein A coefficients and oscillator strengths of the …

Global Characterization Of Stratospheric Sulfate Aerosols By The Atmospheric Chemistry Experiment (Ace), Peter Bernath, Manish Bhusal, Michael Lecours, Chris Boone

Chemistry & Biochemistry Faculty Publications

Stratospheric sulfate aerosol (SSA) is an important part of the Earth's climate system. SSA climate impact is determined in part by particle composition, which has been measured from orbit. The weight percent of sulfuric acid in SSA has been determined from atmospheric infrared transmittance spectra recorded with the Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) in limb geometry using the Sun as a light source (solar occultation). The global average SSA composition varies from about 50 to 80 percent with lowest values during the Antarctic winter. Atmospheric extinction at a wavelength of 1 μm was included in the analysis to …

Carbamate-Functionalized N-Acetyl-D-Glucosamine Derivatives For Gel Formation And Chemiluminescent Properties Of Their Metallogels, Pooja Sharma, Pramod Aryal, Richard Chen, Alice Mao, Guijun Wang

Chemistry & Biochemistry Faculty Publications

Sugar-based low-molecular-weight gelators are an interesting and useful class of compounds due to their many applications. Several carbamate derivatives of _D-glucose and _D-glucosamine have been previously reported as effective gelators, demonstrating that the fine-tuning of molecular structures can have a profound influence on molecular assembling properties. In this study, a series of 12 3-O-carbamate derivatives of N-acetyl-_D-glucosamine were synthesized in short steps with several derivatives found to be organogelators. The derivatives were screened in 11 different solvents for their gelation properties. Among the series of synthesized compounds, ten derivatives showed gelation in at least one of …

Reconciliation, Draper Matthews

Theses and Dissertations

This thesis exhibition, Reconciliation, examines how memory, loss, and lived experience shape personal identity over time. Through sculptural works composed of cast, blown, and hot-sculpted glass combined with mixed media, the exhibition explores the pressures that life events place upon individuals and the ways those pressures persist, transform, and become integrated into the self. The work considers identity not as a fixed state but as a continual process of negotiation between past experiences, present circumstances, and future possibilities.

Central to the project is the material analogy between glass and human experience. Glass, a material formed under extreme heat and pressure …

The Thing About Stuff: Exploring Consumerism Through Contemporary Print, Collage And Self-Reflection, Alexandra Lee Cox

Theses and Dissertations

The Thing about Stuff is an exhibition of editioned prints and book forms that pertain to personal and societal contradictions under capitalism. I use a combination of collage, design, print, traditional research and writing to form a better understanding of my place in capitalism by redefining my participation in it. Historical and contemporary research in combination with self-reflection and artmaking assists in my exploration of consumerism through the lens of human-object relationships. This body of work translates my own material desire for an audience through intentional composition, limited color pallets and intentional display. The accompanying supportive statement focuses on the …

Toxic Culture In All-Star Cheerleading: A Qualitative Research Study, Jodie Fairbank

Theses and Dissertations

All-star cheerleading emerged in the late 1980s. It has grown exponentially over the last thirty years. Today, over 250,000 individuals participate in competitive cheer. The nature of this sport pushes elite athletes and has organizations worldwide. It incorporates stunting, dance, tumbling, and performance. In recent years, there have been numerous news stories, documentaries, and court cases that indicate that, behind all the glitter and excitement of the sport, there may be many instances of a toxic culture that is allowing the youth who participate in this sport to be susceptible to environments that may be detrimental to them in many …

Sidelining The Public, Anya Bernstein, Glen Staszewski, Wendy E. Wagner

Faculty Scholarship

This Article challenges the widely held view that Congress is the American government’s institution closest to the people, while administrative agencies are unaccountable and unresponsive. Providing a systematic, side-by-side institutional analysis, we compare the actual practices and capacities of these two institutions to engage affected publics in policymaking. We find that despite the democratic bona fides of an elected legislature, agencies possess superior capacities, more evolved practices, stricter rules, and stronger incentives for meaningful public engagement. Yet these capacities have been eroded—particularly over the last 50 years—by intensifying legal, political, and managerial obstacles. The Supreme Court and political actors have …

Research Collection Lee Kong Chian School Of Business

Here we review recent work in the personnel selection field. We open with two sections, the first focusing on meta-analytic validity research on well-established predictors and the second on new measurement approaches. These include moving from a holistic to a modular view of predictors; from face-to-face to asynchronous video interviews; from resumes to social media assessments; from multiple choice to constructed response; and to using artificial intelligence to develop, administer, and score tests, among approaches. We then review developments in estimating validity, including issues in correcting validity estimates for error of measurement and restriction of range. We address technical issues …

Brand Collaborations: Spillover Effects Of A Broadened Mind, Jin K. Han, Yong Seok Sohn, Bernd H. Schmitt

Research Collection Lee Kong Chian School Of Business

The current research focuses on the overlooked spillover implications of brand collaboration on downstream consumer decisions. The authors propose that brand collaborations create a broader consumer mindset, which can inadvertently encourage choices beyond the brand franchise. The authors identify collectionist behavior (i.e., the tendency to collect items from specific product lines) and time-induced construal level as moderators of this unintended negative downside effect. A retail field study and five laboratory experiments provide evidence for the effect, the underlying mindset mediator and the moderating conditions. We recommend that retailers and brand owners assess both positive and negative outcomes of brand collaborations …

Workplace Mistreatment: A Systematic Review Of Interventions And Future Research Agenda, Gillian Leake, Albert Amankwaa, Irene Elisabeth De Pater

Research outputs 2022 to 2026

Workplace mistreatment has garnered increasing attention from scholars and so has calls for research on interventions to prevent or reduce this phenomenon. However, there has been a lack of broad systematic approaches to studying interventions and existing reviews on workplace mistreatment interventions have predominantly focused on workplace bullying and incivility in the healthcare sector. To address these gaps and set an agenda for future interventions research, our review focuses on interventions for all forms of mistreatment and across industries and organizations. We reviewed 40 intervention studies from 38 articles finding a wide variety of interventions for specific forms of workplace …

Reframing Narratives, Reclaiming Futures: Antiracist School Counseling And Black And Brown Girls In Stem, Renae D. Mayes, Lia D. Falco, Shontell Zenon, Dequindre Hughes, Yijia Chen, Lydia Ross, Medha Dalal

Journal of College Access

Black and Brown girls often have educational experiences that stifle their career aspirations, especially in STEM fields. These experiences can be exacerbated by educators who misunderstand and refuse to recognize their STEM potential, thus limiting their opportunity to build STEM identities. School counselors can disrupt these experiences through antiracist practices that cultivate homeplace and joy for Black and Brown girls to heal and grow while working to address harmful policies and practices. In this paper, authors discuss how school counselors can specifically use antiracist school counseling practices to support Black and Brown girls in STEM as a part of multi-tiered …

College Vs. Career School Counseling: How Role Differentiation Shapes Student Postsecondary Expectations And Outcomes, Sam Luby

Journal of College Access

This study examines how high school counselor role differentiation, specifically college preparation and workforce readiness, relates to students’ postsecondary expectations (2012) and early outcomes (2016) using nationally representative data from the High School Longitudinal Study of 2009 (HSLS:09). Multinomial logistic regression models controlling for academic achievement and socioeconomic factors indicate that the presence of college-preparation counselors significantly reduces the likelihood of students entering the workforce without postsecondary enrollment.

Workforce-preparation roles show no statistically significant association with postsecondary outcomes, though they are more common in schools serving higher-need populations. Academic performance and poverty status remain strong predictors across models. Findings underscore …

The Limits Of Daca: Affordability- And Access-Related Barriers To Health Professions Education, Nicole Perez, Laura Hirshfield

Journal of College Access

The U.S. is currently facing a shortage of health professionals from underrepresented backgrounds. One potential pathway to decrease this shortage is through the Deferred Action for Childhood Arrivals (DACA) program, a policy that provides temporary relief from deportation for individuals who migrated to the U.S. before age 16. This study, using 15 life-history narrative interviews, investigates the experiences of Latinx young adults who were pursuing health professions education or working as health professionals. Nine of the participants were DACA recipients, while the remaining six were second-generation (i.e., children of immigrants). An iterative, inductive approach to data analysis was used to …

Non-Gaussian Phenomena In Light Scattering And Applications, Shubham Atul Dawda

Graduate Studies Theses and Dissertations 2026

Physical reality is rarely deterministic; which, when probed by electromagnetic fields that also fluctuate, leads to observables that are most efficiently modelled as statistical processes. At equilibrium, this is usually achieved by invoking the Gaussian statistics of underlying physical processes, however, in practice, one often encounters out-of-equilibrium conditions where Gaussian descriptions may not suffice. Such situations are plentiful in nature– from biology to astronomy. This dissertation addresses several non-Gaussian phenomena associated with light scattering, and includes specific models’ derivations, experimental techniques developments, and demonstrations of potential applications. The systematic presentation will consider circumstances that infringe upon specific assumptions of the …

Exploring The Experiences Of Late Age-On-Arrival Multilingual Learners In Postsecondary Education, Robyn D. Ecklund

Graduate Studies Theses and Dissertations 2026

Multilingual learners (MLs) are the fastest growing population in the United States public school system (Biondi et al., 2024; Kanno & Cromley, 2013; Perez & Morrison, 2016; Varghese & Fuentes, 2020). Within this population of students, there is a subset of students that arrive in the United States during secondary school. These “late age-on-arrival” students face significant linguistic, cultural and social challenges in their pursuit of postsecondary success after high school (Kanno, 2021; Kanno & Cromley, 2013; Perez & Morrison, 2016). This interpretative phenomenological analysis sought to answer the research question: what are the lived experiences of late age-on-arrival MLs …

Independent And Interacting Effects Of Co-Presence And Social Media 'Likes' On Online Disinhibition, Margaret M. Doheny

Graduate Studies Theses and Dissertations 2026

Social media platforms have fundamentally transformed interpersonal communication by creating environments in which behaviors are publicly reinforced through visible social feedback systems such as “likes.” Although prior research has linked online environments with increased disinhibition and negative behavior, existing literature has primarily focused on anonymity and invisibility as the primary mechanisms underlying these effects. However, the mechanistic role of physical and psychological co-presence in driving online disinhibition has received little empirical investigation. The central aim of the present study was to determine whether reduced social presence and the selective reinforcement of negative content contribute to online disinhibition and anticipatory reward-seeking …

Optically-Pumped Semiconductor Optical Amplifiers, Dhruvkumar Desai

Graduate Studies Theses and Dissertations 2026

Semiconductor optical amplifiers (SOAs) offer a low-cost, compact solution for power amplification needs in an optical communication system compared with the dominant erbium-doped fiber amplifiers (EDFAs). They can also provide a wide gain bandwidth. However, conventional electrically-pumped SOAs suffer from larger noise figures, low saturation power, and polarization dependence, in comparison with EDFAs. We propose an optically-pumped SOA (OP-SOA) that will maintain the benefits of conventional SOAs while closing the gaps in other amplifier performance metrics. The underlying reasons for optical pumping are twofold. First, optical pumping allows higher carrier injection and thus "population inversion." Second, optical pumping decouples carrier …

Machine Learning Modeling Of In-Situ Effective Thermal Conductivities And Ablation Behaviors Of Ceramic Matrix Composites Under Hydrogen Combustion Environments For Gas Turbine Engines, Jayanta Bhusan Deb

Graduate Studies Theses and Dissertations 2026

Through the integration of experimental characterization, machine learning, deep learning, numerical modeling, and physics-informed artificial intelligence, this dissertation explores the thermal performance of polymer-derived ceramic matrix composites (CMCs) for hydrogen combustion environments. The polymer infiltration and pyrolysis (PIP) process was used to create Yttria-stabilized zirconia (YSZ)-fiber-reinforced ceramic matrix composites, which were then experimentally assessed under hydrogen torch and hydrogen combustion conditions typical of next-generation gas turbine and aerospace propulsion systems. Front- and back-surface temperature measurements were used to continually monitor thermal reactions, and post-test microstructural characterization and numerical simulations were carried out to evaluate material integrity and heat-transfer behavior. To …

Flow Field Characterization Of The Hyperreact Vitiated Hypersonic Wind Tunnel, Erik R. Fernandez

Graduate Studies Theses and Dissertations 2026

Reliable interpretation of hypersonic ground-test data requires knowledge of the thermochemical state delivered to the test section, especially in combustion-heated facilities where the gas is chemically altered before nozzle expansion. This thesis investigates the HyperReact vitiated hypersonic wind tunnel using the effective specific-heat ratio, γeff, as an experimentally inferred indicator of the coupled chemical and gas-dynamic behavior of hydrogen-air vitiated flow. HyperReact produces high stagnation temperatures through hydrogen-air combustion before expanding the mixture through interchangeable converging-diverging nozzles. During this expansion, temperature-dependent specific heats, molecular-weight changes, finite-rate chemistry, and internal energy relaxation can modify the relationship between Mach number, pressure ratio, …

Gaining Voice, Creating Opportunity: An Exploration Of Non-Native English-Speaking Students’ Sources Of Self-Efficacy In U.S. College Public Speaking Classrooms, Desiree M M Flores-Molina

Graduate Studies Theses and Dissertations 2026

This qualitative dissertation explores the sources of public speaking self-efficacy among non-native English-speaking international students enrolled in U.S. college public speaking courses. The study applies Bandura's social cognitive theory to examine how students describe the experiences that shape their confidence and perceived ability to succeed, with attention to mastery experiences, vicarious experiences, verbal persuasion, and physiological and affective states. It also considers how classroom practices and instructor support contribute to or constrain students' confidence.

Data were collected through semi-structured student interviews, guided reflection artifacts connected to major speech assignments, and key-informant interviews with public speaking instructors. Thematic analysis was used …

Lost Innocence, Found Martyrdom: Childhood War Exposure, Narratives, And Militancy In Hezbollah, Léa Faure

Graduate Studies Theses and Dissertations 2026

What explains participation in armed insurgent groups? Existing literature has examined psychological, individual, structural, and organizational dynamics of mobilization, but rarely looks at all three in tandem. This can be problematic, since these explanations cannot on their own explain variations in participation. Research on the effects of individual exposure to war-related violence also cannot explain why in conflict-ridden, organizationally dense environments, mobilization is still relatively rare despite widespread violent exposure. This study creates a unified theory of participation around the interaction between childhood exposure to war-related violence and relatable timely group narratives. Focusing on the case of Hezbollah in Lebanon, …

From Designation To Implementation: A Qualitative Study Of Support Structures For Latinx Students At A Hispanic-Serving Institution, Steven A. Freeman

Graduate Studies Theses and Dissertations 2026

This study addresses the persistent misalignment between the enrollment-based designation of Hispanic-Serving Institutions (HSIs) and the extent to which these institutions implement intentional practices that support Latinx student success. As HSIs continue to grow nationally, it is critical to examine whether institutional efforts move beyond symbolic designation toward meaningful “servingness,” particularly given the increasing reliance on these institutions to advance social mobility and educational attainment for Latinx students. The purpose of this qualitative study is to explore the support structures an HSI provides to promote Latinx student success and to examine Latinx students’ perceptions of the effectiveness of these supports. …

Minimizing Performance Overheads For Crash-Consistency In Disaggregated Persistent Memory, Khan Shaikhul Hadi

Graduate Studies Theses and Dissertations 2026

Compute express link (CXL) enables persistent memory disaggregation with memory pooling and hardware managed multi-host memory sharing capability, resulting in better resource utilization, increased scalability. Persistency-aware applications need to manage crash consistency across the system which results in significant performance overhead. This dissertation systematically investigates performance overhead to achieve crash consistency in disaggregated persistent memory and proposes solutions to enable persistency-aware application scaling for distributed system. First, we study persistent parallel programming to scale computation capability beyond single processor and determine the underlying hardware limitation to adopt lock-free data structure. We propose hardware support to design durable atomic instruction (DAI) …

Various experimental findings are validated through collaborations via density functional theory (DFT). By combining temporal, mass, and energy-resolved measurements, this work provides molecular-level insight into the elementary processes governing light-driven surface reactions. The photodissociation dynamics of CH₃I adsorbed on TiO₂(110), TiO₂(100), and amorphous silicon oxide surfaces are examined …

Examining Teachers’ Data Usage Using The Teacher Data Use Survey, Natasha L. Hawkins

Graduate Studies Theses and Dissertations 2026

The United States spends approximately 2.7 billion dollars on classroom assessments and local exams for K-12 students (SIMBA, 2019).  However, despite this financial investment and the adoption of data-driven frameworks such as Multi-Tiered System of Support, the U.S. Department of Education found that only 55% of teachers used student data to make instructional decisions (U.S. Department of Education, 2007).  This study aims to explore the psychological and organizational factors that influence teachers’ data use when making instructional decisions.

This study used the Teacher Data Use Survey (TDUS) to investigate the extent that teachers’ use of data could be predicted by …
