Infrastructure Of Lack: Defining Caribbean Vernacular Networks, Luis Rivera Jiménez

archipelagos: a journal of Caribbean digital praxis

This article offers a theoretical reflection on the forms and meanings of networks in the Caribbean, moving beyond traditional definitions rooted in computation and formal infrastructure. By turning to vernacular, improvised, and culturally embedded modes of exchange—such as in "Club Nintendo" culture and BlackBerry Messenger (BBM) in the Dominican Republic, the DIY internet practices of Cuban users, and the ubiquity of memes and WhatsApp threads across diasporic communities—this piece reframes the concept of the “network” through a Caribbean lens. Rather than seeing the Caribbean as disconnected or technologically incipient, this approach understands the region as a space of creative, strategic, …

Linking Sea Ice Melt, Water-Column Structure, And Particle Distributions In The Weddell Sea, Daniel England

OneUSF Summer Undergraduate Research Symposium

Sea-ice melt strongly influences the coastal waters of Antarctica by lowering surface salinity, reducing vertical mixing, and changing MLD (mixed layer depth). These changes can affect phytoplankton biomass, particle formation, and carbon export. This poster examines how meltwater, and mixed layer depth relate to fluorescence, particle abundance, and particle biovolume in the Weddell Sea region of the Western Antarctic Peninsula. CTD (conductivity-temperature-depth) casts from the Polar Rapid cruise were used to analyze temperature, salinity, density, and fluorescence across multiple transects, and stations. Salinity was used to estimate meltwater percent in the water column, while density and temperature were used to …

Evaluating Biochar Composites For 3d Printing Wetland Restoration Media, Lily Boyer, Melody Ngaaso

OneUSF Summer Undergraduate Research Symposium

Nutrient pollution from urban stormwater and agricultural runoff drives eutrophication in coastal wetlands, threatening the ecological function of ecosystems that communities depend on for water quality, flood resilience, and habitat. Floating treatment wetlands offer a nature-based intervention, but conventional planting media provide limited nutrient adsorption capacity and little opportunity for design optimization at scale. This study investigates whether biochar, a porous, high-surface-area carbon material, can be incorporated into extrudable biocomposites to enhance ammonium, nitrate, and phosphate adsorption in floating wetland applications, while remaining safe for sustained contact with wetland plant roots. Four biochar composite recipes were fabricated as standardized cylindrical …

Stalling on sewer inspections is costing homeowners more money and potential health issues down the road. Homeowners play a critical role in the health of local water infrastructure. While it is the local government’s job to oversee that water infrastructure is being maintained, it is the homeowners’ responsibility to ensure the functionality of the private sewer lateral (PSL); the pipe that runs beneath their home and connects to a public sewer main. Immense damage to the home, the homeowner’s wallet, and the environment can result from the impairment of this private line. Previous studies by Tampa Bay Estuary Program (TBEP) …

Chemical Effects Of Microplastics On Photochemistry In A Coral-Associated Zooxanthella, Meghan A. Hennings, Matz Indergard, John E. Parkinson

OneUSF Summer Undergraduate Research Symposium

Coral bleaching is the process by which corals lose their symbiotic microalgae in response to stressful conditions. These photosymbionts, known as zooxanthellae, give corals their color and sustain host growth through mutualistic nutritional exchange. Bleaching events are becoming more common and severe, driving research into coral conservation and the resilience of each partner in the symbiosis. Yet it is unknown how certain pollutants, such as microplastics, may affect bleaching outcomes. Previous research in our laboratory has demonstrated that the presence of polyvinyl chloride (PVC) microplastics inhibits bleaching recovery in sea anemones (a coral model), but it remains unclear whether the …

A Method For Algorithmic Entropy Mitigation And Context Window Equilibrium In High-Dimensional Transformer Architectures, Christopher L. Eckes

Defensive Publications Series

High-dimensional Autoregressive Transformer architectures scale linearly or quadratically in computational, thermodynamic, and financial overhead relative to context window saturation. In continuous multi-turn token processing, models suffer from "Prompt Gravity"—a compounding mathematical distortion of the Softmax attention matrix driven by localized token accumulation. This distortion shifts in-context token weights, resulting in structural degradation, diminished operational return on investment (ROI), and severe "sandbox sycophancy" where factual grounding collapses into localized linguistic coherence.

This paper introduces a decentralized, low-entropy architecture designed to decouple structural grounding from active token processing. By utilizing localized, high-entropy open-weight nodes (e.g., legacy Llama architectures) to simulate an offline, …
