‘A Sense Of The Sea’: Grassroots Culture, Care, And Endurance In Swansea, Cymru, Katy Clark

Dissertations, Theses, and Capstone Projects

This thesis argues that under present conditions, everyday political-aesthetic life is not only about resistance or reproduction but about holding: the work of keeping people, practices, and attachment present and oriented as conditions change. Holding takes the form of care and maintenance; as practices of making, assembling, and imagining; and as the work that keeps open the possibility of renewed attachment to public things and to each other. In the field, this was named as ‘a sense of the sea’, an affective register characterized by wariness, attunement, attentiveness, orientation, and endurance. I am calling this a fragile infrastructure of …

New York City Women’S Experiences With Perinatal Depression Inquiries, Diagnosis, And Treatment Initiation, Caterina Pisciotta

Dissertations, Theses, and Capstone Projects

Perinatal depression represents a significant public health concern, yet many women who experience depression symptoms during the perinatal period (either during pregnancy and/or after birth) do not receive treatment. Initiatives, such as ThriveNYC, were designed to address these gaps by screening and treating perinatal women for maternal depression, integrating screening into routine perinatal care and strengthening pathways to treatment. Using representative survey data collected between 2016 and 2021 via the Center for Disease Control and Prevention’s Pregnancy Risk Assessment Monitoring System (PRAMS), this study examined trends in perinatal depression inquiries (a proxy for “screening”) and postpartum diagnosis, as well as …

Mesoscopic Scaling Of Microwave Transmittance And Disorder-Induced Alignment, Israel Kurtz

Dissertations, Theses, and Capstone Projects

This thesis presents microwave measurements and numerical simulations of wave propagation and transmission through random mesoscopic waveguides. We analyze the scaling of mesoscopic microwave conductance, including departures from Ohm’s law near channel openings, which are frequencies at which new propagating modes enter the system, and the evolution of modal phase alignment within the medium, which leads to the observed diversity of transmission eigenvalues. We extend the transmission matrix formalism to all sample depths using the flux matrix, which relates the flux amplitude within the sample to the incident flux, and decompose the flux at each sample depth into forward- and …

Ultrafast Spectroscopy Of Organic Materials In Strong Light–Matter Interaction And Terahertz Optics, Kamyar Rashidi

Dissertations, Theses, and Capstone Projects

Ultrafast spectroscopy is a powerful tool for investigating phenomena that occur on extremely short timescales and for probing ultrabroadband spectral responses enabled by its ultrashort laser pulses. These capabilities are essential for advancing both the fundamental understanding of light–matter interactions and the development of next-generation optoelectronic technologies. The first part of this thesis investigates the ultrafast dynamics of organic exciton–polaritons and their application to controlling molecular excited-state processes using momentum-resolved pump–probe spectroscopy. A major challenge in these systems is the dark-state problem, where photoexcitation predominantly populates long-lived excitonic reservoir states that obscure the in trinsic dynamics of the hybrid light–matter …

Opportunities For Learning Through Object Exploration During Early Physical Therapy: Physical Therapists’ And Caregivers’ Assistance And Interference Behaviors, Michele Goncalves Maia

Dissertations, Theses, and Capstone Projects

Early physical therapy (EPT) for infants with motor delays has traditionally emphasized motor milestone acquisition, yet growing evidence indicates that motor and cognitive development are fundamentally interconnected. Grounded in embodied cognition and developmental cascade theories, this dissertation conceptualized object exploration as a primary mechanism through which infants learn during EPT and examined how intervention approaches and adult behaviors shape opportunities for object exploration. Using retrospective analyses of video-recorded EPT sessions, two studies investigated how intervention approaches and adult behaviors influence infants' opportunities to learn through object exploration. Study 1 compared object exploration in the START-Play (SP) intervention and Usual Care …

Theoretical Analysis And Performance Interpretation In Thomas Adès’S Traced Overhead, Han Chen

Dissertations, Theses, and Capstone Projects

While many post-tonal composers avoid any inkling of tonality by embracing dissonance or breaking tonal resolutions, Thomas Adès does not shy away from the traditional harmonies that strongly relate to tonal music, such as the circle of fifths, major and minor triads, and the horn-call motif, but adopts several intervallic systems that govern all the notes, including aligned cycles, parsimonious voice leading, and the twelve-tone aggregate.

To examine how Adès uses these intervallic systems to repurpose traditional harmonies, this dissertation presents a close tonal analysis of his solo piano work Traced Overhead. Integrating historical, pianistic, and extramusical contexts, this …

Gene-Environment Interactions In Cardiovascular Aging: Volunteering, Polygenic Risk, And Biomarker Change In European And African Ancestry Populations, Seoyoun Kim, Byeongju Ryu, Erin Ware, Koichiro Shiba, Cal J. Halvorsen

Brown School Faculty Publications

Volunteering has been associated with better cardiovascular health, but whether this association varies by genetic susceptibility to cardiovascular disease remains unclear. This study examined associations between volunteering and cardiovascular biomarkers, assessed associations between biomarker-specific polygenic scores (PGSs) and these outcomes, and tested whether polygenic risk moderated volunteering–biomarker associations among U.S. adults aged 51 years and older.

Synthesis Of Fe-Doped Porous Carbon Catalyst Derived From Coconut Shell Waste Using Ferric Nitrate Nonahydrate (Fe(No3)3.9h2o) As An Iron Precursor, Ilham Lestadi Putra, Sukarni Sukarni, Heru Suryanto

Journal of Mechanical Engineering Science and Technology (JMEST)

Renewable energy from lignocellulosic biomass is a promising alternative to fossil fuels. Coconut shell (CS) waste is a favorable precursor for porous carbon due to its high carbon content, abundance, and non-food nature. However, conventional biochar often has limited surface area and catalytic active sites, hindering its effectiveness as a catalyst. While Fe-based modifications are promising, the use of ferric nitrate-assisted activation of coconut-shell-derived porous carbon remains underexplored. This research focused on developing an Fe-doped porous carbon catalyst from CS via ultrasound-assisted impregnation, followed by activation in a tube furnace. CS biochar was produced through pyrolysis at 550 °C and …

Prune: A Patching Based Repair Framework For Certifiable And Privacy-Robust Unlearning Of Neural Networks, Xuran Li, Jingyi Wang, Xiaohan Yuan, Peixin Zhang

Research Collection School Of Computing and Information Systems

Machine unlearning has emerged as a key mechanism for enabling the “right to be forgotten” in neural network models, allowing the selective removal of specific training data upon request. Existing approaches typically rely on retraining models with the remaining data, which is computationally expensive and difficult to verify, especially when deployed models are distributed or resource-constrained. To address this challenge, our prior conference work introduced PRUNE, a patching-based framework that formulates unlearning as a neural network repair problem. PRUNE achieves targeted forgetting by learning lightweight patch networks that redirect model predictions on the data to be unlearned while preserving performance …

Neural Symphony Of Flow Experience: Evidence For High-Dimensional Metastable Dynamics, Abdelrahman B. M. Eldaly, Kris Zhangguang Kang, Fiona Fui-Hoon Nah, Leanne Lai-Hang Chan, Keng Siau, Xiao Fan Liu, Richard Huskey, Langtao Chen, Tejaswini Yelamanchili, Rene Weber

Research Collection School Of Computing and Information Systems

Flow, an optimal experience characterized by deep immersion and engagement in an activity, has been extensively studied in behavioral research. However, its neural dynamic mechanism remains poorly understood. In a within-subject video gaming experiment, we captured neural activity underlying flow, boredom, and anxiety using a 64-channel electroencephalogram (EEG) system. Compared to boredom and anxiety, flow exhibits the highest global functional connectivity, metastability, and dimensionality of dynamic functional connectivity patterns, suggesting that flow is a highly adaptable process that is supported by high-dimensional neural dynamics. Unlike previous studies that focused on identifying static or localized brain activity, we examine the neural …

Generalized Logit Adjustment: Improved Fine-Tuning By Mitigating Label Bias In Zero-Shot Vision Models, Beier Zhu, Qianru Sun, Xun Yang, Hanwang Zhang

Research Collection School Of Computing and Information Systems

Foundation models like CLIP allow zero-shot transfer on various tasks without additional training data. Yet, the zero-shot performance is less competitive than a fully supervised one. Thus, fine-tuning and ensembling are also commonly adopted to better fit the downstream tasks. However, we argue that such prior work has overlooked the inherent biases in foundation models. Due to the highly imbalanced Web-scale training set, foundation models are inevitably skewed toward frequent semantics, and thus the subsequent fine-tuning or ensembling is still biased. In this study, we systematically examine the biases in foundation models and demonstrate the efficacy of our proposed Generalized …

Smart: When Is It Actually Worth Expanding A Speculative Tree?, Lifu Wang, Pan Zhou

Research Collection School Of Computing and Information Systems

Tree-based speculative decoding accelerates autoregressive generation by verifying a branching tree of draft tokens in a single targetmodel forward pass. However, existing methods prioritize maximizing token-level likelihood or the number of accepted tokens while ignoring a critical “efficiency paradox”: the computational overhead of drafting and verifying big trees can grow super-linearly, particularly at scale. This often leads to negative wall-clock speedup when batch sizes increase or hardware saturation limits are reached. To address this, we propose SMART, a System-aware Marginal Analysis framework for Runtime Tree construction. SMART reformulates tree expansion as a hardware-aware optimization problem that directly maximizes end-toend speedup. …

The Game Within: An Anthropological Approach To Games And Play, Nehal Maged Mohamed

Theses and Dissertations

This thesis is based on an eighteen-month ethnography of El Ghawasa, an Egyptian play-based organization that designs educational games, tools, and services. Claiming that El Ghawasa, with its ethos of play, seeks to create an alternative to the capitalist corporate structure. Through tracking how this organization navigates ruptures, negotiates constraints, and experiments with different practices and internal restructuring, I explore the possibilities and limitations of El Ghawasa, while attempting to resist absorption by the very system it opposes. I ask: when the rules keep changing (while the logic of the capitalist corporate structure remains the same), and the boundaries of …

All Works

Deepfake technology synthesizes and manipulates digital content to produce artificial videos in which an individual’s identity, facial appearance, or actions are convincingly altered. These forgeries can be highly realistic, posing serious risks to trust in digital media and undermining personal reputation, dignity, and the integrity of public discourse. This paper presents the Lightweight Deepfake Evaluation Framework (Light-wDEF)– a resource-efficient, reproducible framework tailored for large-scale evaluation of visual deepfake detectors on modest hardware. Light-wDEF combines deterministic frame sampling, batched MTCNN face extraction, streaming append-only storage with lazy offset indexing, online Albumentations augmentations, stratified splits with class-aware sampling, and robust training (AdamW, …

Inflation-Differential Rule Versus (De Facto Soft-Peg) Discretion: Exchange-Rate Management Approach In Developing Economies, Behnam Ebrahimi, Mohammad Vaez Barzani Dr.

Bulletin of Monetary Economics and Banking

Many developing and emerging economies officially report a managed floating exchange-rate regime tailored with a fundamental exchange rate management approach, while in practice operating a de facto soft peg, characterized by discretionary, near-constant exchange-rate depreciation aimed at dampening inflation expectations. This discretionary approach—often justified as a pragmatic response to inflationary pressure—produces a hybrid regime that lacks the transparency and credibility emphasized in IMF policy guidance. This study evaluates whether substituting Discretionary Soft-Peg Exchange Rate Management approach with an Inflation-Differential Rule of Exchange Rate Management approach, which links exchange-rate adjustments to the inflation differential between domestic and rest of the world, …

The Nusantara Capital City (Ikn) Relocation: Autocratic Legalism And The Marginalization Of Local Communities, Imam Syafi'i, Dian Aulia

The Indonesian Journal of Socio-Legal Studies

The first phase (2022–2024) of the Nusantara Capital City (IKN) relocation prioritizes the construction of the city's physical infrastructure under the “Nusa Rimba Raya” concept. During this phase, the massive development of supporting infrastructure, including government buildings, official residences, toll roads, ports, and the VVIP airport, has driven increased demand for materials and land, impacting areas beyond the delineation of IKN. However, the power-driven approach in the capital relocation policy has led to socio-ecological injustices for indigenous and local communities by disregarding meaningful public participation and environmental sustainability. Land acquisition through the Land Bank (Bank Tanah), which prioritizes investment, along …

Karhunen-Loève Modes For Coherent Arrays, Jack E. Mccrae, Santasri R. Bose-Pillai, Steven T. Fiorino

Faculty Publications

The optimal modes for correcting atmospheric turbulence on coherent arrays are determined. These Karhunen-Loève modes are eigenvectors of a covariance matrix. Creating this covariance matrix requires knowledge of the power spectrum of the turbulence, the aperture geometry, and a basis set for the matrix. The Kolmogorov power law is ordinarily chosen here for the turbulence spectrum. By choosing the phase on each array subaperture element minus the phase averaged over all subapertures as this basis, infinite values in the variances and covariances can be avoided. The piston mode of the whole array, which would otherwise also be infinite, is thus …

The Relationship Between Adverse Childhood Experiences, Protective And Compensatory Experiences, And Parenting Attitudes Among Fathers, Kylie Schmidt

Dissertations

Adverse childhood experiences (ACEs) are defined as potentially traumatic events that occur in childhood particularly between the ages of 0 and 17 years that negatively influence long-term health, relational functioning, and parenting practices (Centers for Disease Control and Prevention, 2026; Felitti et al., 1998; Merrick et al., 2019). Conversely, protective and compensatory experiences (PACEs) have emerged as protective factors that foster resilience and possibly buffer against the adverse outcomes of ACEs (Narayan et al., 2018). As the existing research has greatly focused on mothers, little is known about how men’s early life experiences shape their parenting attitudes, particularly during the …

Never Say Never: The Interdependence Of No-Till And Strategic Deep Tillage In Sustainable Production Systems, Therese Mcbeath, Stephen Davies, John A. Kirkegaard

Grain and Other Field Crops Research Articles

No-till (NT) farming systems are a defining feature of modern conservation agriculture (CA), providing benefits for soil and water conservation, operational efficiency, and resource use efficiency. However, long-term NT adoption across Australian dryland cropping systems has also intensified inherent and emergent soil constraints, including subsurface compaction, topsoil water repellence, acidity, and nutrient stratification. These constraints limit crop water use and yield potential. In the sandy soils of southern and western Australia, strategic deep tillage (SDT) has been developed in otherwise NT systems to alleviate these constraints. Advances in machinery design and controlled traffic systems have enabled deeper, more effective amelioration …
