Effects Of Metals On Persulfate Activation For The Decomposition Of Pfas, Malu Deav Devadasan

Civil Engineering Dissertations

Per- and polyfluoroalkyl substances (PFAS) are persistent environmental contaminants widely used in industrial and consumer products due to their unique physicochemical properties. Their resistance to degradation, potential for bioaccumulation, and associated adverse health effects have prompted increasing regulatory attention, including the establishment of drinking water standards for six PFAS compounds by the U.S. Environmental Protection Agency in 2024.

Current PFAS treatment technologies are often energy-intensive and costly or generate secondary waste streams requiring further management. Meanwhile, this research investigated transition metal-catalyzed advanced oxidation processes for PFAS decomposition in water under ambient conditions. Previous studies demonstrated effective degradation of perfluorocarboxylic acids …

Gaussian Process Regression–Based Uncertainty Quantification For Unmanned Aircraft System Traffic Management And Advanced Air Mobility Applications, Aakarshan Khanal

Mechanical and Aerospace Engineering Dissertations

Uncertainty quantification has gained significant attention in recent years as a research area in dynamical systems. Mathematical representations of the physical system, combined with an understanding of model uncertainties, enable the propagation of uncertainty in temporal space, which allows us to make informed decisions. However, what if the true dynamics of the system is unknown or too complex to define explicitly? In such cases, the system’s behavior can instead be inferred or learned from observed input–output data rather than from an analytical or physics-based model. To this end, this dissertation focuses on developing a data-driven framework for nonparametric dynamics modeling, …

Guided by Cyber-Routine Activities Theory (Cyber-RAT), this study evaluates the pilot implementation of the Seniors Harnessing Internet Education for Lasting Defense (SHIELD) Training-the-Trainer program, designed to prepare law enforcement officers and community leaders to deliver cybercrime prevention education to older adults. A key innovation of SHIELD is its integration of interactive game-based simulations, which allow participants to practice verification, refusal, and reporting behaviors in realistic cybercrime scenarios. Following the December 2025 pilot session in Boston, semi-structured interviews were conducted with 12 participants from law enforcement, …

Vishing And Smishing Perpetrators And Their Victims In Nigerian Slums, Lateef J. Adeyemo, Tirimisiyu Y. Olabulo, Idenyi G. Peter

International Journal of Cybersecurity Intelligence & Cybercrime

This study investigates the personal accounts of both perpetrators and victims to better understand the techniques and strategies used in vishing and smishing schemes. It adopts a qualitative cross-sectional design across three Lagos slums (Ajegunle, Amukoko, and Ijora-Badia), using snowball sampling to recruit 20 victims and 10 perpetrators for in-depth interviews. Findings reveal that perpetrators impersonate trusted entities using low-tech tools (pre-registered SIMs, bulk SMS apps) to exploit trust. Selective morality emerges among offenders, with some repaying known victims due to guilt while exploiting strangers, alongside a mentorship culture where experienced scammers train newcomers. Poverty and peer influence normalize the …

From Authorization To Loss: A Blockchain Forensic Analysis Of Transaction-Level Mechanisms In Cryptocurrency Airdrop Scams, Chanwoo Shin, Kyung-Shick Choi

International Journal of Cybersecurity Intelligence & Cybercrime

This study examines how transaction-level mechanisms and offender strategies influence variation in monetary loss in airdrop scam incidents. Grounded in Cyber-Routine Activities Theory (Cyber-RAT), the study conceptualizes financial harm as occurring within decentralized environments where users’ online behaviors, particularly transaction authorization, intersect with limited digital capable guardianship. Data were drawn from 112 validated airdrop scam cases reported on Chainabuse.com between January and December 2025. Blockchain forensic analysis using Breadcrumbs was conducted to reconstruct transaction pathways, identify exchange interactions, and detect …

Cloud-Computing Costs And Financial Reporting: How Classification And Disclosure Choices Shape Comparability And Valuation, Salma Askar

Dissertations and Theses

Cloud computing has become a central component of firms’ information technology infrastructure, yet the accounting treatment and disclosure of cloud-related expenditures remain subject to managerial judgment under ASC 350-40. This thesis examines whether variation in cloud˗computing disclosures is associated with differences in firms’ information environments and reporting behavior. Using textual analysis of 10-K filings for U.S. public firms from 2004 to 2025, the study constructs measures of cloud-related disclosure volume, optimistic tone, and linguistic intensity. It examines their association with analyst forecast error, analyst forecast dispersion, financial statement comparability, and real earnings management. The results indicate that cloud disclosure characteristics …

Evolution Of A Novel Neuronal Sex-Specifically Spliced Gene In Mosquitoes, Yael Norohasimbola Tsitohay

Student Theses and Dissertations

Female mosquitoes from many species require a blood meal from an animal host as a protein source for egg development and successful reproduction. The majority of mosquito species are generalists in their host preference, feeding on a range of animals including mammals, birds, and amphibians. However, a small fraction of mosquito species have evolved a preference for human hosts. These species are mainly found in the genera Aedes, Culex, and Anopheles, and they have created a global health crisis due to their ability to transmit deadly human pathogens including dengue virus, Zika virus, West Nile Virus, and …

Ancient Immune Systems: Sensing And Signaling In Bacterial-Phage Conflict, Cameron Grace Roberts

Student Theses and Dissertations

Viruses are among the most significant selective pressures shaping the evolution of life on Earth. In the microbial world, bacteriophages (phage) are bacterial viruses and drive a continuous evolutionary arms race that has led to an extraordinary diversity of bacterial defense mechanisms [1]. These systems are thought to have provided the evolutionary foundation for numerous eukaryotic immune strategies [2]. Experimental studies have validated many of these anti-phage defense systems and revealed the mechanisms by which they disrupt phage infection [3]. Nonetheless, major gaps persist in our understanding of how bacterial immune systems recognize bacteriophage infection to trigger immunity. This dissertation …

The Influence Of Dna Methylation On Both H2a.Z Nucleosome Dynamics And The Zinc Finger And Homeoboxes Transcription Factor Family, Rochelle M. Shih

Student Theses and Dissertations

DNA methylation represents a widespread and heritable modification that exerts substantial influence on chromatin organization and function in many eukaryotic genomes. The presence of DNA methylation has been strongly linked to transcriptional regulation, in both activating as well as repressive ways, though exactly how a small chemical mark can enact such drastic and seemingly opposing effects on gene expression remains an open question. In my thesis work, I describe the influence DNA methylation has on two classes of chromatin proteins, the histone variant H2A.Z and the Zinc Finger and Homeoboxes (ZHX) family of transcription factors. DNA methylation and H2A.Z preferentially …

The Reinnervation Of Sensory Hair Cells Following Lesion Of The Lateral Line Cranial Nerve, Rohan S. Roy

Student Theses and Dissertations

Loss of hearing is a prevalent sensory pathology in the United States and worldwide. A significant proportion of deafness is attributed to sensorineural hearing loss, which often involves damage and retraction of the nerve fibers that relay auditory information between the mechanosensitive hair cells of the inner ear and the brain. The restoration of physiologic hearing would require the regeneration of nerve fibers back into the sensory epithelium of the cochlea, followed by the reinnervation of appropriate hair cell targets. Nerve regeneration studies in humans and other mammalian models are lacking due to the limited accessibility of the inner ear. …

Investigations Into Why Human (But Not Mouse) Ku70/80 Is Essential Reveal A Role For Human Ku70/80 In Ribosome Biogenesis, George Zakusilo

Student Theses and Dissertations

The requirement of Ku70/80 for ribosome biogenesis in higher primates explains otherwise perplexing essential nature of this double-strand break (DSB) repair factor. We have ruled out telomere protection or DSB repair as the essential function ofKu70/80. Instead, unbiased genome-wide analyses pointed to a role in ribosome biogenesis. Human Ku70/80, but not mouse Ku70/80 is enriched in the nucleolus at the Dense Fibrillar Component (DFC) periphery, likely via co-evolved protein-protein interactions with nucleolar factors. Consistent with its localization in the nucleolus, human Ku70/80 null cells exhibit ribosomal RNA (rRNA) processing defect and consequent shutdown of protein synthesis offer a direct explanation …

Influence Of The Solar Cycle And Interplanetary Shocks On Turbulence At 1 Au, Sujan Prasad Gautam

Dissertations

This thesis studies the effect of the solar cycle and interplanetary shocks on turbulent fluctuations at 1 AU. We examine the solar cycle dependence of turbulence cascade rates corresponding to the total turbulence energy using the methodology developed by Adhikari et al. that utilizes a Kolmogorov phenomenology. Turbulence cascade rates are derived using 25 years (1995–2020) of Wind spacecraft plasma and magnetic-field observations. We find that the total turbulence energy cascade rate changes with the solar cycle, such that the cascade rate is largest during solar maximum and smallest during solar minimum. It is positively correlated with the solar wind …

Comparative Visions For U.S. Group-Based Asylum Proposal, Lauren N. Hughes

Scholarly Articles

Images of asylum seekers and migrants desperate to enter the United States at the southern border abound in U.S. media. Less familiar to the American public, but intertwined with the highly politicized modern migration crisis, is the ever-growing backlog of pending asylum applications before both the Asylum Office and Immigration Courts. This backlog has many causes, including underresourced agencies, a growing number of asylum applicants, the high evidentiary burden and complexities inherent to asylum law, and the lack of counsel for many asylum seekers. In response to this crippling backlog, some scholars propose the adoption of a “group-based” asylum mechanism. …

The Complexities Of The Bilingual Advantage, Melisa Sierra

Behavioral Neuroscience Honors Papers

The bilingual advantage hypothesis, which proposes an enhancement of executive functions in bilinguals, remains heavily debated with inconsistent findings across studies. This study investigated working memory performance in bilingual and monolingual young adults using a modified n-back task with an interruption while recording EEG activity. Participants completed 1-back, 2-back, and 3-back conditions across the pre-interruption phase and a post-break 2-back condition. Behavioral measures (accuracy and response times) were analyzed alongside ERP, focusing on P300 and sustained activity components, were analyzed. Results showed a decrease in accuracy as task difficulty increased from 1-back to 3-back, indicating the expected effects of higher …
