Reconstituting Histories Of Filipino Families With Chinese Ancestry: Methodology, Sources, And Relevance, Richard T. Chu

Kritika Kultura

Conducting one’s family history can enrich not only one’s own sense of self but also a nation’s history, especially in a country like the Philippines where oligarchic families have historically had an impact on the nation’s society, economy, and society. Many of these families are Tsinoy (Chinese-Filipino). Only few, however, have undertaken to reconstitute their histories. This essay discusses the various methods, sources, resources, and various frameworks (e.g., transnational, gendered) that one can use in the reconstitution of Tsinoy family histories. It also explains the significance that such family histories have in reframing and broadening our understanding of Philippine history.

A Filter-Based Model Of Visual Recognition, Olivia Rose Bockler

Arts & Sciences Electronic Theses and Dissertations

Visual recognition, a key perceptual process, enables primates to identify faces, food, tools, and potential threats in their environment. Cortical neurons along the ventral visual stream—spanning from early visual cortex (V1) through inferotemporal cortex (IT), with long-range projections to ventrolateral prefrontal cortex (vlPFC)—are essential for visual recognition. Traditional models propose that neuronal representations increase in complexity in each stage of this pathway, culminating in object-specific representations in higher-order cortex. However, this hypothesis remains debated, particularly as artificial visual models have countered that individual neurons along this pathway may function more as filters contributing to distributed representations of objects. Thus, this …

The Role Of Mir-34a In Pathological Neovascularization As Seen In Age-Related Macular Degeneration, Jason Colasanti

Arts & Sciences Electronic Theses and Dissertations

Age-related macular degeneration (AMD) is a leading cause of irreversible vision loss among the elderly, affecting nearly 200 million people worldwide. AMD impacts the macula, which is the small, central area of the retina responsible for high-acuity vision. The exudative (wet) form of late-stage AMD is the most severe, accounting for ninety percent of the legally blind patients with AMD. Wet AMD is characterized by the abnormal growth of blood vessels and fluid leakage beneath the retina known as choroidal neovascularization (CNV), directly resulting in vision loss. While anti-VEGFa targeted therapies have been the gold standard for ameliorating wet AMD …

Technology Development Of High-Resolution Single-Cell Lineage Tracing For Cell Reprogramming Systems, Sadie Vanhorn

Arts & Sciences Electronic Theses and Dissertations

A critical element of cell identity is the cell that created the observed cell. This parent cell dictates many aspects of its identity, whether measured by function, phenotype, or specific assays. The cell’s lineage impacts the ability of the cell to differentiate into final cell types in development or successfully reprogram in direct cell reprogramming. Here, we evolve molecular barcoding techniques to increase the resolution of lineage recording at single-cell resolution. Using single-cell RNA-sequencing as the readout for this measurement, polyadenylated reporter gene transcripts with engineered 3’ untranslated regions were designed to initially label and then record lineage information. While …

Multi-Omic Analysis Of Phototrophic Extracellular Electron Uptake In Novel Rhodovulum Spp. Isolated From A Marine Estuary, Emily J. Davenport

Arts & Sciences Electronic Theses and Dissertations

Microbial metabolisms are incredibly versatile and dynamic, allowing adaptive strategies for growth in even the most limiting environments. For an ever-increasing number of microbes, this includes utilizing soluble or insoluble inorganic mineral species as electron donors, driving geochemical cycles and microbial metabolisms. This metabolic function of transporting electrons derived from the extracellular environment across cell membranes is called extracellular electron uptake (EEU). Within (photo)autotrophs, (p)EEU also sustains CO2 fixation to cell biomass, implicating a potentially fundamental role of microbial carbon cycling in aquatic and soil ecosystems. A model metabolic scheme of pEEU occurring in natural environments is photoferrotrophy, which pairs …

Results: The project showed strengths in system description, team task allocation, and data sharing, but had lower scores in engaging societal actors throughout the project cycle.

Discussion: We identified the underexplored influence of problem wickedness as a …

Discrimination, Depression, And Somatization: The Impact Of Spirituality And Covid-19, Katherine Aloisi

ETD Collection

The current study aims to fill gaps in the literature examining relationships between psychological symptoms (depressive, somatic), spirituality, ethnic discrimination, and stress related to the 2019 novel coronavirus (COVID-19) pandemic. It is hypothesized that stress caused by COVID-19 is associated with greater perceived discrimination, depressive symptoms, and somatic symptoms. It is also hypothesized that individuals experiencing heightened COVID-19 stress, and perceived discrimination would report increased depressive and somatic symptoms. Greater spiritual well-being is similarly hypothesized to decrease COVID-19 stress, depressive s, and somatic symptoms. Data was collected via self-report measures, including the COVID Stress Scale (CSS; Taylor et al., 2020), …

The Significance And Impact Of Traditional Naming Practices In The Meru Community Of Tanzania, Wariaeli Ismaeli Pallangyo, Eliakimu Sane

Capacity-Weighted Figures-Of-Merit For Battery Transport Metrics, Cj Sturgill, Christopher Sutton, Julian Schwenzel, Morgan Stefik

Faculty Publications

New battery materials with improved transport are needed. Typical measurements yield widely varying voltage-dependent diffusivities and reporting practices are diverse. Some materials (e.g. first-order phase change) have most redox occur at a specific voltage and may be sufficiently represented by singular transport metrics. Many rapid intercalation materials, however, exhibit second-order phase transitions with redox over a broad voltage range. How should such cases be compared? The use of capacity-weighted average values is suggested where voltage-dependent metrics are consolidated into representative descriptors as figures-of-merit. Examples are elaborated where differential capacity (dQ/dV) is used to derive a …

Tree Rings Reveal Mixtures Of Aspen And Spruce Exhibit Greater Drought Resilience In A Planted Field Experiment, Jéssica Chaves Cardoso, Linhao Wu, Marcel Schneider, Charles A. Nock

Aspen Bibliography

Boreal forests provide a wealth of ecosystem services, many of which are linked to forest productivity. Climate change is expected to increase the frequency, duration, and severity of drought, and undermine the productivity of western boreal forests. Favouring species mixtures has emerged as a potential strategy to increase forest resilience to drought. To test the hypothesis that mixtures of trembling aspen and white spruce were more productive than pure stands because they were more resistant and resilient to drought, we analyzed community and species responses to drought utilizing measurements of annual growth obtained from stem disc samples from a planted …

Does Market Accessibility Improve Household Food Security? Evidence From Small-Holder Maize Producers In Southern Tanzania, Monica Sebastian Kauky

Journal of Humanities and Social Sciences

This study investigated the impact of market accessibility on household food security among smallholder maize producers in Southern Tanzania, utilizing data from a sample of 407 households primarily engaged in maize farming. Tobit and probit models assessed the relationship between food security and market access. Contrary to expectations, the findings revealed no significant association between market access and food security. Instead, the results underscored the importance of resource availability, indicating that larger farm sizes and higher household wealth indices significantly reduce the risk of food insecurity. These findings suggest that rather than focusing exclusively on enhancing market access, policymakers should …

Mild Traumatic Brain Injury In Justice-Involved Individuals And Executive Function Consequences On Transition And Reintegration Into The Community, Alaina L. Randerson

Student Capstone Papers

The United States has the highest documented incarceration rate in the world (Carson, 2022), with an increasing number of justice-involved individuals (JII) potentially affected by mild traumatic brain injury (mTBI). Despite the high prevalence of mTBIs in the general population, limited research exists on the prevalence and impact of mTBIs in JII. Preliminary evidence suggests that the prevalence of mTBIs in incarcerated individuals is 50 times higher than in the general public (Siegler et al., 2017). This study aimed to explore the lived experiences of JII with mTBI, focusing on the origin of mTBIs, executive dysfunction, and the occupational barriers …

Social Learning And Cultural Enrichment For Fish Welfare, Chiawen Chiang, Becca Franks

Animal Sentience

This commentary examines how understanding animal culture—shared behaviors and knowledge transmitted through social learning—plays a role in advancing welfare practices for captive fishes. Despite extensive evidence of fishes' complex sociocultural capacities, their psycho-social needs remain underestimated and unmet in zoos and aquaria. We explore what considering fish culture might mean for welfare practices: diverse social learning opportunities, cultural development, and thoughtful group management. More knowledge about wild fishes' lives will help bridge the gap between their full, complex lives and current captive welfare practices.

Using Bivalves As An Indicator For Fecal Bacteria, Kamala Chuss

Honors Scholar Theses

This project focuses on the integration of fecal bacteria from warm-blooded animals into bivalve tissue, and the utilization of bivalves as an indicator for fecal bacteria in waterways. Bivalves may give a more representative long-term average of fecal bacteria in water as compared to direct water testing. The primary objective is to create a standard operating procedure to use bacterial testing of bivalves as a proxy for bacteria concentration in the water. This method can be used in places where bivalves do not already exist by adding them to a body of water, or by collecting bivalves that already exist …
