Bridging Gaps In Stem: An Evaluation Of A Stem Intervention Program And Its Impact On Degree Attainment And Career Pathways For Low-Income Undergraduate Students, Amanda L. Surman

Dissertations - ALL

Persistent disparities in Science, Technology, Engineering, and Mathematics (STEM) degree completion and career attainment continue to disadvantage students from low-income, firstgeneration, and underrepresented racial and ethnic backgrounds, despite sustained national efforts to diversify the STEM workforce. STEM Intervention Programs (SIPs) have emerged as promising strategies to address these inequities, yet limitations in SIP evaluation literature including the lack of comparison groups, limited longitudinal data, and minimal attention to psychosocial outcomes impede our understanding of their long-term impact. This dissertation uses a mixed-methods, three-project design to evaluate the Strategic Undergraduate STEM Talent Acceleration INitiative (SUSTAIN), a comprehensive SIP at a private, …

Subclinical Cardiometabolic Disease Risk In Adults With Autonomic Nervous System Dysfunction, Alaina Glasgow

Dissertations - ALL

Autonomic dysfunction (AD) is a precursor for cardiometabolic disease development; however, identifying AD and its associated risks presents significant challenges due to multi-system dysregulation and diverse symptom presentation. We examined subclinical cardiometabolic disease risk in AD and the utility of simple autonomic symptom assessments to identify subclinical disease risk. Study 1 thematically explored potential associations linking Postural Orthostatic Tachycardia Syndrome (POTS) to cardiometabolic disease risk. Neuropathic and hyperadrenergic POTS phenotypes may be related to metabolic dysregulation through autonomic neuropathy, sympathetic activity, inflammation, insulin resistance, and elevated vasoactive gut hormones. Study 2 investigated subclinical cardiovascular disease risk in POTS and whether …

I tried to understand this issue by using mixed methods, primarily consisting of semi-structured in depth interviews, supplemented by ethnographic fieldwork and a brief consultation of english-language newspaper archives. I conducted 95 interviews in total, and clocked in around 80 hours moving around the city and engaging in a mobile ethnography. The first empirical question that I asked relates to the state and urban transportation planning. I wanted to understand what assumptions regarding class-based, gender-based and …

Essays On The Health And Labor Market Effects Of Menopause And Menopause Hormone Therapy, Lucia Elvira Torres Frasele

Dissertations - ALL

This dissertation explores how menopause and its medical management affect women’s health and labor market outcomes. Despite the centrality of reproductive transitions in the life course of women, economic research has largely ignored menopause, a biologically and socially significant milestone marking the end of fertility. This omission is surprising, given well-established medical evidence that links menopause to increased risks of health conditions that may impair the ability to work. The dissertation addresses this gap through two chapters that examine the causal impact of menopause and Menopause Hormone Therapy (MHT) on health and labor supply using two distinct empirical strategies. The …

Co-Catalyst Modified Mn-Doped Semiconductor Hybrid Nanostructures For Enhanced Photocatalysis, Walker John Macswain

Dissertations - ALL

Semiconductor nanocrystals (NCs) are sought after for their applications in photocatalysis and photovoltaics and due to their impressive optical and electronic properties. In photocatalysis, an important green energy transformation is sunlight utilization to produce hydrogen gas via photocatalytic water splitting. However, the photocatalytic performance of pristine semiconductors is low due to their inherent fast charge recombination. The use of co-catalysts with semiconductor NCs leads to enhanced photocatalytic product generation; noble metal co-catalysts, such as Pt, Au, Ag, and Cu and noble-metal-free metal hydroxide co-catalysts on either chalcogenide CdS or perovskite CsPbX3 (X = Cl, Br) semiconductors were synthesized to study …

Security And Privacy In Deep Learning And Dynamic Decision Making, Feng Wang

Dissertations - ALL

Recent years have seen rapid advances in machine learning applications, such as deep reinforcement learning (DRL) for optimizing wireless resource allocation and federated learning (FL) for enabling privacy-preserving, distributed model training. In these systems, machine learning agents learn and control resources at the edge. However, these systems face significant vulnerabilities to adversarial threats. In a DRL-based mobile communication scenario, an intelligent attacker can selectively jam specific channels and cause critical failure in victim users' performance. In an FL system, a privacy adversary who eavesdrops on shared gradient information can reconstruct the users' private data. This dissertation focuses on both types …

Theorizing Technology Integration: The Case Of Smart Grid Technologies At Electrical Utilities In The United States, Ehsan Sabaghian

Dissertations - ALL

Over the past decade, the energy culture as a whole and electric industry specifically has been going through wide-scale disruptive and consequential transformation. The pressure for these changes comes from different fronts: Decarbonization (switching to renewable sources and implementing carbon reduction policies); Digitalization (adoption and investment on smart digital technologies, infrastructure, and networks), Decentralization (distributed nature of behind-the-meter resources), and Demand (growing demand from customers for high quality, affordable electricity). In response to these pressures, electric distribution utilities were continuously adopting smart grid technologies (most notably Advanced Meter Infrastructure (AMI) and enterprise-wide applications) to create new organizational capabilities. Now, utilities’ …

Distributed Sovereignty: Law, Community, And Authority In The Political Theories Of Al-Māwardī, Al-Juwaynī, And Al-Fārābī, Ahmet Çelik

Dissertations - ALL

ABSTRACT This dissertation examines the concept of sovereignty in classical Islamic political thought through a comparative analysis of three major thinkers—al-Māwardī (d. 450/1058), al-Juwaynī (d. 478/1085), and al-Fārābī (d. 339/950)—each representing a distinct epistemic tradition: jurisprudence (fiqh), speculative theology (kalām), and philosophy (falsafa). Employing a conceptual and textual methodology, the study reconstructs a theory of distributed sovereignty in Islamic thought, in which political authority is not centralized in a singular sovereign but dispersed across three interrelated domains: legitimate authority, lawgiving, and governance. Drawing on primary texts—including al-Aḥkām al-Sulṭāniyya, Tashīl al-Naẓar, Ghiyāth al-Umam, al-Madīna al-Fāḍila, al-Siyāsa al-Madanīyya, Kitāb al-Milla, and Iḥṣāʾ …

Race, Space, Taste In The Postwar U.S.: Three Independent Studies On Urban Restaurants In Syracuse, New York, Huseyin Zeyd Koytak

Dissertations - ALL

This dissertation examines how racial inequality shapes the survival, visibility, and strategic adaptation of restaurants in postwar Syracuse, New York. It investigates how commercial food spaces reflect, reinforce, and negotiate racialized patterns of urban development, consumer taste, and economic opportunity. Drawing on longitudinal business and demographic data, a computational content analysis of online restaurant reviews, and original interviews with immigrant restaurateurs, the study integrates quantitative, computational, and qualitative methods to illuminate how race and space co-produce outcomes in the urban food economy. The first empirical chapter shows that Black-majority neighborhoods face higher commercial volatility and shorter restaurant survival, while white-majority …

An Examination Of Student Adherence And Intervention Complexity Within A Class-Wide Cover-Copy-Compare Intervention, Kaytlin Ann Nelson

Dissertations - ALL

Cover-Copy-Compare is a self-management intervention strategy developed to improve students’ academic performance, particularly in spelling. In academic intervention research, it is often assumed that students are completing the intervention as intended, yet this is seldom examined during intervention implementation or subsequent data analysis. The purpose of the present study was to extend the empirical literature on students’ intervention adherence by examining Cover-Copy-Compare permanent products to assess whether the complexity of the intervention (i.e., targeting six versus nine spelling words) contributed to a student’s ability to adhere to core intervention components. For the purposes of the present study, data from one …

A Model Of Blind Quantum Diffusion, John Carver Vining

Dissertations - ALL

We introduce the Blind Quantum Diffusion Network (BQDN), a quantum computational framework designed for distributed systems operating under conditions of partial observability and asynchronous communication. BQDN generalizes the structure of Generalized Boolean Networks (GBNs) by replacing classical multivalued logic nodes with quantum registers, enabling the use of superposition, entanglement, and unitary evolution to model distributed computation and state propagation. Building on the properties of W-states and quantum teleportation protocols, the BQDN leverages entangled coin registers and a token-based control mechanism to implement blind diffusion across a graph. The system achieves synchronization-free evolution without classical coordination by embedding decision-making within quantum …

Lattice And Continuum Anomalies : Bridging The Gap, Arnab Pradhan

Dissertations - ALL

In this thesis, we explore anomalies both in the continuum and on the lattice, and attempt to establish a connection between the two frameworks. In the continuum limit, we work with Kähler-Dirac fields, while in the discrete setting, we focus on staggered fermions. To facilitate insights relevant to the growing field of quantum computing, we consider a Hamiltonian formalism in addition to the path integral. Anomalies offer a concrete bridge between ultraviolet (UV) and infrared (IR) physics, understanding how anomalies manifest on the lattice versus in the continuum provides a powerful predictive framework. By numerically studying lattice gauge theories, we …

Marine Heatwaves Detected By A Network Of Buoys Along The Entire Us West Coast Shelf, Gavin Plume, Ryan K. Walter, Piero L.F. Mazzini, Michael Dalsin

Physics

Marine heatwaves (MHWs), prolonged periods of anomalously warm waters, pose an increasing threat to marine ecosystems globally. While satellite-based data offer insights into MHW patterns, coastal upwelling regions are prone to satellite biases and require long-term in-situ datasets for accurate characterization. Using two decades of temperature data from 22 surface buoys distributed along the US West Coast continental shelf (10–50 km offshore) spanning nearly 2000 km of coastline, we investigated, for the first time, coast-wide patterns of MHWs in this valuable region. The spatial extent of MHWs varied from 100% of buoys during the 2014–2016 North Pacific MHW, to less …

Characteristics And Effectiveness Of Premarital Thalassaemia Educational Interventions Worldwide: A Scoping Review, Maisarah N. Anwar, Nik Nairan Abdullah, Dalila Roslan, Aimi N.M. Ruzlin

Sultan Qaboos University Medical Journal

Thalassaemia, a hereditary blood disorder, remains under-recognised due to limited awareness, particularly among young people. This scoping review aimed to evaluate the characteristics and effectiveness of premarital thalassaemia educational interventions globally. Following PRISMA-ScR guidelines, six databases were searched for English-language studies targeting adolescents and young adults. Eight studies met the inclusion criteria, and data were extracted using a standardised form adapted from the Joanna Briggs Institute, focusing on intervention characteristics, outcomes and key findings. Most studies involved school students and young adults from culturally diverse, resource-limited settings. The interventions—traditional, technology-based or culturally adapted—consistently improved knowledge (P < 0.001). However, behavioural outcomes, such as increased uptake of screening, were inconsistent. While educational strategies enhanced knowledge effectively, socio-cultural barriers limited the translation into behavioural changes. These findings support the need for future interventions to integrate behavioural change theories, leverage digital tools and address cultural sensitivities to improve their overall impact.

Innovative Approaches To Estimating Sessile Oak Stem Volume: Comparing Additive Models And Ensemble Machine Learning, Maria J. Diamantopoulou, Abbas Şahi̇n, Ramazan Özçeli̇k

Turkish Journal of Agriculture and Forestry

Sessile oak is an important deciduous forest tree species across Türkiye and Europe. Estimating individual tree and stand volumes is essential for growth and yield models, as these predictions play a critical role in assessing forest management, economics, and fire risk. In pursuit of this goal, nonlinear seemingly unrelated regression (NSUR) was used for the simultaneous fitting of stem volume components, and compared to three ensemble machine learning techniques: gradient boosting regression (GBr), XGBoost regression (XGBr), and random forest regression (RFr). NSUR accounts for correlations between error terms across different equations, leading to more efficient parameter estimates than if each …
