The Invisible Crop: Harnessing Root System Architecture In Heirloom Collards For Climate-Resilient Urban Agriculture, Vincent Antonio Brazelton

Arts & Sciences Graduate Student Theses and Dissertations

Growing food in urban spaces often means working within variable, resource-limited environments, creating a need for crops that can withstand heterogeneous growing conditions. Heirloom collards (Brassica oleracea var. viridis) are known for their aboveground diversity and cultural importance, but much less is known about the variation that exists belowground. This dissertation examines root system architecture (RSA) diversity across 19 historically underutilized heirloom collard accessions using a multi-scale phenotyping approach that includes controlled gel-based imaging of seedlings and 2D imaging of mature field-grown root systems. Across both seedling and mature stages, heirloom collards showed substantial variation in RSA. These differences revealed …

The Influence Of Circadian Rhythm Disruption And Apoe4 On The Prognosis And Progression Of Alzheimer’S Disease, Kayla Bradby

Graduate Student Dissertations, Theses, Capstones, and Portfolios

Alzheimer’s disease is characterized by cognitive decline and memory loss and is the most common form of dementia. Genetic factors such as apolipoprotein E have been significantly associated with AD development and progression, most specifically the APOE4 isoform. Emerging evidence has shown that when the body’s circadian rhythm, the 24-hour dark/light cycle, is disrupted, the potential to develop a neurodegenerative disease such as AD increases. The purpose of this literature review is to examine the relationship between AD, circadian rhythm, and the APOE isoforms. This review puts a particular emphasis on the APOE4 isoform, as it has been shown to …

Wille Zum Wald: Nietzsche’S Discovery Of Forest Bathing, Gary Shapiro

Philosophy Faculty Publications

In the fourth part of our “The Forest as a Living Foundation” series, the distinguished American Nietzsche scholar Gary Shapiro investigates new angles on Nietzsche’s bonds to the woods: the philosopher’s personal enthusiasm for what is increasingly called “forest bathing,” the science behind how this practice benefits body, mind, and spirit, and the sheer pleasure of breathing fresh air, in woodland and wherever else we can find it. Shapiro’s essay showcases why this particular Lebensraum matters, not just for our individual well-being, but for the health of the entire planet.

Nascent Adam17 Synthesis Potentiates Gpibα Cleavage In Resting And Stimulated Stored Platelets, Shayan Askari, Harriet Ghansah, Christopher D. Mansi, Timothy J. Stalker, Lawrence E. Goldfinger

Cardeza Foundation for Hematologic Research

Platelet concentrates stored at room temperature have a shelf life of 5 to 7 days. During storage, platelets undergo glycoprotein cleavage by metalloproteases, notably cleavage of glycoprotein Ibα (GPIbα) by a disintegrin and metalloprotease 17 (ADAM17), which leads to decreased posttransfusion reactivity and recovery. To investigate the putative roles of nascent synthesis of ADAM17 in GPIbα shedding and platelet function during room temperature platelet storage. Human platelets maintained in autologous plasma were treated with naked endonuclease-resistant ADAM17 or control short inhibitory RNA (siRNA) and monitored for molecular and cellular effects during storage. Platelet-specific Adam17-deleted mice were generated, and the dynamics …

The quiz invites students to select on a map those countries and territories they consider part of the Caribbean, prompting reflection on the diversity of perspectives shaping Caribbean identity. Drawing from the discourse of critical cartography and digital pedagogy, we …

Tun Up: Building Digital Dancehall Fashion Archives From An Artist’S Perspective, Grayson Chong

archipelagos: a journal of Caribbean digital praxis

This article investigates the opportunities and challenges of building a dancehall fashion archive with particular emphasis on the transition from the material to the digital. As an artist-scholar, I use my own dancehall fashion collection as a case study to explore the process of digitizing material artifacts (in this case, fashion and textiles). I focus on dancehall fashion in particular because it speaks to themes of resistance, self-fashioning, and creativity in the global fashion market. Throughout the article, I highlight what the transition between material and digital affords scholars and public audiences. In particular, I ask: "How do we retain …

A Metadata Analysis Of Anthropological Scholarship About Haiti And The Dominican Republic, Tess Kulstad González, Pauline Kulstad González, Zoe Grubbs, Hongyuan Zhang

archipelagos: a journal of Caribbean digital praxis

This article presents the results of a metadata and content analysis of anthropological research about Haiti and the Dominican Republic available in the Anthropological Literature database and in the Journal of Latin American and Caribbean Anthropology. This analysis shows that anthropological knowledge about Haiti and/or the Dominican Republic, produced in Haiti and the Dominican Republic, is included less than scholarship published outside the island. In addition, our analysis indicates that research that pertains to both countries, or that considers transnational and/or inter-island processes has been infrequent. Furthermore, that which exists is not as discoverable or visible as research that focuses …

“Un Compromiso Con La Tierra”: Digital Placemaking In The Art Of Rosaura Rodríguez’'S Instagram Stories, Jeannine Murray-Román

archipelagos: a journal of Caribbean digital praxis

From a recording of a hot pink flower on a foggy hillside, its leaves trembling slightly in the wind, to the ink made from its petals pooling onto white cardstock, Puerto Rican artist Rosaura Rodríguez shares her experimental processes on Instagram stories, fifteen seconds at a time. Instagram is a fraught platform that encourages aesthetic homogeneity, and yet, continues to function as a site for developing micro-poetic techniques. This article focuses on Rodríguez’s in-process Instagram Stories, and particularly the “Highlights” feature which allows her to archive her working processes for two of her projects: 1. Temporada, a self-published comic that …

Alterations In Intracellular Pathways By Structured Acoustics Across Mammalian Model Systems, Mary B. Holahan, A'Niya Jackson, Jose Rumbaut-Clark, Elaina Schuler, Arnav Chavda, Thanh Mai Nguyen, Junaina Nazneen, Ana Beatriz-Melgar, Sarah Hedenstad, Emily Hernandez

OneUSF Summer Undergraduate Research Symposium

Music can be defined as structured sound that serves as a “universal language” capable of influencing emotion, cognition, and social connectivity in humans. Its formal application into the medical profession began in the 20th century, following World War I and II.  Human subject research involving music therapy has since reported a myriad of health benefits such as those on emotional (e.g., anxiety, depression, and stress), neurological (e.g., cognitive impairment, sleep issues, and dementia), and physical well-being (e.g., pain, multiple sclerosis, fibromyalgia). However, the impact of such structured acoustics on biological processes at the cellular and molecular level remains unclear. Towards …

Memory-Based Lock-Free Inter-Process Communication, Vlad Popa, Andy Hung, Atneya Nair, Mikhail Naganov, Shunkai Yao, Eric Laurent, Jean-Michel Trivi

Defensive Publications Series

A lock-free inter-process communication (IPC) system can utilize shared memory to broadcast system events from a single writer process to multiple reader processes. The system employs a shared memory circular queue and an atomic sequence counter that increments before and after write operations, allowing readers to determine if an active write is occurring. By calculating an active queue index using the sequence counter, reader processes can safely access previously committed historical state data without blocking or busy-waiting. This non-blocking architecture prevents IPC message queue overflows for frozen or suspended background applications, eliminates priority inversion, and avoids the thundering herd problem …

Generative Synthesis Of Context-Aware Media Recaps And Alternative Narratives, Dev Daftari, Akash Verma

Defensive Publications Series

Systems and methods can use generative artificial intelligence to synthesize personalized media content. For example, when a user returns to a series, a system can generate a dynamic recap designed to be spoiler-free based on a user's last-viewed point, for instance, by retrieving relevant plot information from a media knowledge graph. The technology could also generate alternative narrative scenes based on user prompts, for example, by using system guardrails to promote stylistic consistency with the source material. These techniques may provide personalized user interactions, potentially improving viewer re-engagement with serialized content and extending interaction with media franchises within a media …

Natural Language Navigation Of Media Via Generative Ai And A Multimodal Index, Dev Daftari, Akash Verma

Defensive Publications Series

Finding specific moments in media can be challenging, as certain methods like timeline scrubbing or keyword searches may not align with a user's descriptive memory of a scene. A system can facilitate media navigation through natural language queries. For example, a system may create a time-stamped, multimodal index of a media asset by analyzing its visual, auditory, and textual content. When a user provides a descriptive query, a generative artificial intelligence model can semantically evaluate the request against the index to identify a corresponding media segment and its timecode. The system could then provide the timecode to a media player …

We Don't See Race, We See Blue: A Case Study Of Police Unions As Racialized Organizations, Sarahfina Aubrey Peterson

Dissertations and Theses

In the late 1960s, police began to unionize. Today, they are the most well-organized labor force in the United States, with 70% to 80% of sworn officers now represented by a union. Though it has been decades, little scholarship has developed about how police unions affect policing. Much of the research that does exist uses race-neutral frames to address an organization steeped in racial history. This study aims to address this gap in scholarship, in part, by introducing race as a motivation for and explanation of organizational output.

This research applies Victor Ray's racialized organizations theory to police unions. I …

The independent variable was a poster with humorous and factual elements displayed at the point of choice in the dining center. The primary dependent variable was the percentage of vegan entrees chosen out of the total number of vegan and meat entrees served. The secondary dependent variables were the number of vegan entrees prepped and served, and the percentage of each entree that was served out of …

Molecular Pathogenesis And Genomic Profiling Of Fusobacterium Nucleatum: A Review Of Virulence Determinants & Antimicrobial Resistance Mechanisms In Dental And Systemic Infections, Mawahb Hatem Mones, Thariat Abdualrahman Al-Joubori, Ibrahim Faisal Ibrahim

Muthanna Medical Journal

Fusobacterium nucleatum is one of the key bacteria in the oral microbiota, which plays a key role in the structural integrity of dental plaque, an anaerobic bacterium. Emerging clinical evidence has increasingly linked this opportunistic pathogen to severe systemic pathologies, notably colorectal cancer and adverse pregnancy outcomes. This review synthesizes current genomic and molecular insights to elucidate the complex mechanisms driving fusobacterial virulence and antimicrobial resistance (AMR). We critically discuss the roles of key adhesins, such as FadA and Fap2, in modulating host cell signaling and facilitating immune evasion. Furthermore, we determine the genomic architecture involved in the transfer …

Electrochemical Determination Of Terbutaline Using A Sno2 Nanoparticle-Modified Carbon Paste Electrode, Rauf Gulamov, Şenol Alpat, Si̇bel Kilinç Alpat

Turkish Journal of Chemistry

Terbutaline hemisulfate (THS), a selective beta-2 agonist, is preferred as a bronchodilator for the treatment of asthma and bronchitis, as well as a tocolytic agent to delay labor in acute situations during premature birth. The use of beta-2 agonists above a certain dose is considered doping in sports competitions. Therefore, it is important that they be determined with high sensitivity and selectivity within a short analysis time. In this study, a SnO2 nanoparticle-modified carbon paste electrode was developed for the determination of THS. Cyclic voltammetry and differential pulse voltammetry were employed as electrochemical methods. The operating conditions of the developed …

Chitosan Microparticle-Based Antibacterial Nasal Barrier Formulation And In Vivo Evaluations, Güli̇z Ak, Ayça Erek, Tuğba Karakayali, Şadi̇ye Çeti̇n, Şenay Şanlier

Turkish Journal of Chemistry

Microorganisms remain a major cause of infectious diseases, emphasizing the need for alternative and complementary antimicrobial strategies. In this context, plant-derived materials have attracted increasing attention for their antimicrobial and protective properties. Chitosan, a biocompatible and cationic biopolymer, has emerged as an effective carrier system for encapsulating such plant-derived components. In this study, chitosan microparticles were prepared through ionic gelation followed by spray drying and loaded with thyme oil and olive leaf extract. The resulting microparticles exhibited an average size of approximately 1.8 μm and a total phenolic content of 23 mg GAE/g. These microparticles were incorporated into a glycerin–starch …

Selective Loss Of Primary Cilia And Neurotrophic Signaling In G51d Α-Synuclein Mice Highlights A Common Pathway To Parkinson’S Disease, Yu-En Lin, Ebsy Jaimon, Youngdoo Kim, Annabeth Loftman, Aaran Vijayakumaran, Benjamin D W Belfort, Claire Y Chiang, Benjamin R Arenkiel, Huda Y Zoghbi, Suzanne R Pfeffer

Duncan NRI Faculty and Staff Publications

Parkinson's disease is characterized by dopaminergic neuron loss and accumulation of α-synuclein aggregates in the brain. G51D α-synuclein knock-in mice provide a genetically and clinically relevant model of disease, exhibiting early olfactory deficits, age-dependent motor impairment, and progressive phospho-α-synuclein accumulation. In multiple Parkinson's disease models, striatal cholinergic and parvalbumin interneurons, as well as astrocytes, lose primary cilia and the neurotrophic signaling needed to sustain dopaminergic neurons. We show here that G51D α-synuclein mice share these phenotypes. Phospho-Ser129 α-synuclein accumulation correlates with cilia loss in cholinergic interneurons but not in spiny projection neurons that accumulate higher phospho-α-synuclein levels. In the piriform …

Acemannan/Alginate Composite Hydrogels Promote Sto Cell Spreading And Metabolic Activity, Hong Yongxing, Tharasanit Theerawat

The Thai Journal of Veterinary Medicine

Alginate-based hydrogels are widely used as biocompatible scaffolds. However, their limited cell-adhesive properties restrict their application in tissue engineering. This study aimed to fabricate acemannan/alginate (ACE/ALG) composite hydrogels and evaluate their cytocompatibility and ability to support STO cell spreading and metabolic activity. Composite hydrogels were prepared by blending different concentrations of ACE with alginate, followed by Ca²⁺-mediated ionic crosslinking. Rheological analysis showed that ACE incorporation increased both the storage modulus (G′) and loss modulus (G″) of the hydrogels. Cell viability and morphology were evaluated using Live/Dead staining on day 7, and cellular growth was assessed using an MTT assay on …

The Thai Journal of Veterinary Medicine

Contamination of chicken meat with antimicrobial-resistant bacteria, particularly multidrug-resistant (MDR), colistin-resistant, and extended-spectrum β-lactamase (ESBL)-producing Escherichia coli (E. coli), threatens its safety for human consumption. This study was conducted to determine the prevalence and antimicrobial resistance (AMR) profiles, particularly ESBL production and colistin resistance in E. coli isolated from retail chicken meat in fresh markets in Bangkok, Thailand. A total of 200 (81.6%) E. coli isolates were recovered from 245 chicken meat samples collected from fresh markets across six regions of Bangkok. Among the isolates, 189 (94.5%) exhibited resistance to at least one antimicrobial agent tested, with the …

Spaces Of Transformation, Love, And Poetry: Autoethnographic Reflections On Learning During The 2024 Student Solidarity Encampments And The 2019 Lebanese Thawra, Anna Wessels

Gatherings

This paper utilizes autoethnographic modes to reflect on the student movement in solidarity with Palestine, specifically the spring 2024 student encampment in Washington, DC. I frame this reflection through my experience as a student in a Women and Gender Studies class during the semester of the encampment, as well as through feminist theories of teaching and learning as liberatory practices. I analyze two sites of learning that moved beyond the ideological and physical boundaries of the university into public protest spaces during times of political mobilization: downtown Beirut during the October 2019 Lebanese thawra (revolution) and the student encampments for …

Kinship As Ethical Caring In Genocidal Times, Khawla Badwan, Sunny Singh Prof

Gatherings

As the world bears witness to the first live-streamed genocide¹ in history with full collaboration of the so-called free world, whatever ethics had been defined and legally encoded by imperial powers in the aftermath of the Second World War are no longer functioning or indeed relevant. Instead at individual and collective levels, we must develop a more relational and nested approach to ethical caring; one that moves beyond saviourism and distant witnessing. To demonstrate this relationality, we present our thinking through a dialogic genre of creative and critical reflections and interventions. This dialogue draws and builds on entanglements of …

Conserving Seabirds: Actions Of The Pacific Seabird Group During Its First 40 Years., Craig S. Harrison

Marine Ornithology

The Pacific Seabird Group (PSG), founded in 1972, is “dedicated to the study and conservation of Pacific seabirds and their environment.” During its first 40 years, PSG undertook scores of conservation actions, although as an all-volunteer organization, PSG lacked the capacity to implement many programs or projects. It achieved its conservation goals through leadership, raising issues, bringing the best science to decision makers, and serving as a catalyst for others to act. PSG has been especially influential in six areas: (1) eradicating invasive alien animals from seabird colonies; (2) conserving Marbled Murrelets Brachyramphus marmoratus; (3) protecting seabird colonies in …
