This study assessed the perception and use of digital applications for soil fertility management and conservation strategies among small-scale crop farmers in southwest Nigeria. A total of 376 farmers were randomly selected across the six southwest states. The data collected were analyzed using descriptive statistics. The majority of the farmers relied on perception and other non-scientific approaches such as the appearance of weeds and performance of crops in the previous season to assess soil fertility. Only 1.1% and 0.3% of the farmers assessed soil fertility through soil tests and digital applications, respectively. Most farmers adopted bush fallowing and the use …

Habitat Use And Movements Of Parrotfishes In A Hawaiian Coral Reef Seascape, Senifa F. Annandale, Jason P. Turner, Daniel L. Lippi, Michael Dance, R. J.David Wells, Jay R. Rooker

Faculty Publications

Parrotfishes (family Scaridae) are important to coral reef ecosystems and highly prized by both commercial and recreational fishers in the Hawaiian Islands. Although parrotfishes are known to be strictly diurnal, our knowledge of their habitat use and movement patterns across daily timescales in tropical systems is still somewhat limited. Here, acoustic telemetry was used to determine parrotfish habitat use and movements within a coral reef seascape at Puakō, Hawai‘i. An array of acoustic receivers was deployed in a nearshore reef to track fine-scale movements of two common species: ember parrotfish (Scarus rubroviolaceus) and palenose parrotfish (Scarus psittacus). Transmitters were mounted …

Seaweed As A Resilient Food Solution After A Nuclear War, Florian Ulrich Jehn, Farrah Jasmine Dingal, Aron Mill, Cheryl Harrison, Ekaterina Ilin, Michael Y. Roleda, Scott C. James, David Denkenberger

Faculty Publications

Abrupt sunlight reduction scenarios such as a nuclear winter caused by the burning of cities in a nuclear war, an asteroid/comet impact or an eruption of a large volcano inject large amounts of particles in the atmosphere, which limit sunlight. This could decimate agriculture as it is practiced today. We therefore need resilient food sources for such an event. One promising candidate is seaweed, as it can grow quickly in a wide range of environmental conditions. To explore the feasibility of seaweed after nuclear war, we simulate the growth of seaweed on a global scale using an empirical model based …

The Integrated Cyclone / Esp For Lunar Dust Filtration, Toma Benarfa Moyne, Joseph Jeon, Isabella Kam, Maia Kawamura, Emily Lukas, Emily Schuster, Maxwell Weiner

ENGS 89/90 Reports

The Integrated Cyclone/ESP is a novel air filtration technology developed to remove the entire respirable range of particles from human habitats in the lunar environment. Managing dust has been a major problem on past missions to the moon. Astronauts reported allergy-like symptoms and eye and lung irritation from frequent dust exposure. Moreover, the inhalation of fine particulate matter has been directly linked to long-term cardiovascular and respiratory disorders as well as strokes and premature death. NASA currently employs HEPA filters to purify air in human habitats. The HEPA filter is highly efficient, but requires frequent replacement of filters, which are …

Automated Mapping Of !Nara In Namibia’S Ephemeral River Corridors, Luc Cote, Elise Donovan, Dylan Lawler, Mara Mccollor, Kendall Weingart

ENGS 89/90 Reports

In this project we develop a user-friendly remote sensing program which, given satellite data, accurately returns locations of !nara melons—a keystone plant species local to the Namib Desert of Namibia. To do so, we utilize pre-existing image segmentation techniques in addition to employing a satellite frequency band-based classification approach on each image segment. This tool can be used to provide important information about how !nara distribution is changing temporally and spatially, an indicator for changes in the hydro-climate of the Namib Desert, thus extending researchers’ ability to track and understand climate change in this remote region in an affordable and …

Uv Self-Sterilizing Central Line Catheter, Madeleine Brown, Anna Byrd, Taylor Floyd, Eoin Hourihane, Anna Pahl

ENGS 89/90 Reports

Central-line associated bloodstream infections (CLABSI) are a potentially lethal side effect of central-line catheter insertion and use. Currently, there are no targeted approaches to reduce the risk of developing a CLABSI. This project aims to develop a UV-based sterilization system to sterilize incoming catheter fluid. The final design is a single-channel attachment that attaches to a patient catheter port via Luer locks, with UV-LED diodes placed on top of a quartz glass window in the channel to sterilize fluid as it flows through the device. This report describes four primary technical objectives, including measuring the radiation achieved by UV-LED diodes, …

Multidimensional Data Visualization And Synchronization For Revealing Hidden Pandemic Information, Qi Zhang, Nikhil Maram

Faculty Publications - Information Technology

Visualization is integral to uncovering hidden information in data and providing users with intuitive feedback for decision-making. Data visualization is crucial for transforming complex data into actionable insights across various domains. In recent years, coronavirus disease vaccines have become increasingly available to much of the population. However, the CDC (Centers for Disease Control and Prevention) often fails to consider multidimensional coronavirus pandemic data from a side-by-side perspective, limiting the ability of medical professionals and individuals to compare and interact with comprehensive data visualizations. Effectively displaying coronavirus and vaccination data collected from multiple sources is essential for interpreting pandemic transmission patterns …

Avian Extraembryonic Membranes Respond To Yolk Corticosterone Early In Development, Emily P. Harders, Mitch Agustin, Ryan T. Paitz

Faculty Publications – Biological Sciences

During times of maternal stress, developing embryos can be exposed to elevated levels of glucocorticoids which can affect development and permanently alter offspring phenotype. In placental species, the placenta mediates fetal exposure to maternal glucocorticoids via metabolism, yet the placenta itself responds to glucocorticoids to regulate offspring growth and development. In oviparous species, maternal glucocorticoids can be deposited into the egg yolk and are metabolized early in development. This metabolism is mediated by the extraembryonic membranes, but it is unknown if the extraembryonic membranes also respond to maternal glucocorticoids in a way comparable to the placenta. In this study, we …

Negated Identities In Dominican Art Education, Felix V. Rodriguez Suero

Faculty Publications – Art

Drawing from decolonial theories, I explore the history of art education in the Dominican Republic in the first half of the 20th century. I examine how racial hierarchies were activated in art classes in school through the romanticization of the countryside and the mystification of children’s material culture. A distorted use of rural imagery served to advance the elite’s narrative of White Dominican identity and to normalize a racial imaginary that negated the country’s African heritage. I analyze how national and global discourses that coupled modernity with Whiteness encouraged aesthetic preferences that permeated children’s visual culture and national art. I …

Trauma In Weird Literature: Weird Experiences And Neuropsychiatric Conditions, Mijin Cho

AUCTUS: The Journal of Undergraduate Research and Creative Scholarship

This study aims to explore the element of trauma or shock in weird fiction using H. P. Lovecraft’s “The Colour out of Space” as the focal text. I am interested in the cognitive estrangement and body disfigurement following encounters with the weird, which in this case would be the meteorite’s Colour, on the characters experiencing it in the story, including the Gardners and Ammi. The goal is to investigate our reactions to being pushed past our thresholds as human beings using analysis of characters, diction, and rhetoric in weird fiction stories and non-fiction patient narratives to better understand how weird …

A Three-Dimensional In Vitro Model Of Disease That Improves Preclinical Research By Incorporating Genetic Diversity And Increasing Physiological Accuracy, Akash Jagdeesh

AUCTUS: The Journal of Undergraduate Research and Creative Scholarship

Biomedical research is essential for the discovery of new medications and treatments, and is built upon the cooperation of preclinical (in vitro/vivo) research and clinical trials. However, 85% of treatments successful in vitro/vivo fail in clinical trials, suggesting that in vitro models are poor indicators of clinical success. The issue lies in conventional “two-dimensional” in vitro models containing genetically identical cells grown on a flat plate, which lack the variety of cell types and cooperation/structure found in real tissue. Moreover, 2D in vitro models do not simulate humans’ genotypic variability, which affects both pathophysiology and treatment effectiveness. In contrast, 3D …

Catecholamine Signaling In Ca1 Correlates With Novelty, Movement, And Sleep State, Meenakshi Kakani

AUCTUS: The Journal of Undergraduate Research and Creative Scholarship

Norepinephrine (NE) and dopamine (DA) signaling in the hippocampus are important for normal learning and memory. Genetically-encoded fluorescent indicators of catecholamine binding allow for imaging real-time neurotransmitter dynamics. Previous microdialysis studies have found an increase in hippocampal catecholamines in response to novel environmental exposure or exercise. Since animals move in response to contextual novelty, it is unknown whether the changes in transmitter release are due to novelty or other changes in behavior or arousal. Outside of the hippocampus, arousal, novelty detection, reward, and sleep state are all related to catecholamine signaling. In this study, we use the fluorescent indicators GRAB-DA …

Disability Accommodation And Improving Accessibility In Public Transportation, Alexander Burdette

These areas as specified are physical accessibility, which concerns the built and engineered environment of public transit and surrounding areas; informational accessibility, which concerns the availability and clarity of information passengers need to navigate transit; management accessibility, which refers to the way information processing is handled by transit agencies when exchanging information with transit users; and social accessibility, which deals with the interpersonal environment that public transit creates and facilitates. Specific areas of attention are …

Originalism & Judicially-Enacted Religious Exemptions: Revisiting Employment Division Of Oregon V. Smith, Eric Russell Coykendall

CGU Theses & Dissertations

In the 1963 case Sherbert v. Verner , the Supreme Court read the First Amendment’s Free Exercise Clause to mean that, in certain cases, religious believers should be exempted from otherwise applicable laws. In 1990, the Supreme Court essentially overturned that framework in the case Employment Division of Oregon v. Smith . The Smith case has proved quite controversial, and numerous public-interest law firms, especially those that defend religious litigants, have regularly asked the Court to overturn it in favor of a re-application of the Sherbert precedent. Their contention is often that the Smith ruling is inconsistent with the original …

The Specter Of Representation: Computational Images And Algorithmic Capitalism, Samine Joudat

CGU Theses & Dissertations

The processes of computation and automation that produce digitized objects have displaced the concept of an image once conceived through optical devices such as a photographic plate or a camera mirror that were invented to accommodate the human eye. Computational images exist as information within networks mediated by machines. They are increasingly less about what art history understands as representation or photography considers indexing and more an operational product of data processing.

Through genealogical, theoretical, and practice-based investigation, this dissertation project traces a lineage of computation through images from early cybernetics to contemporary machine learning under algorithmic capitalist conditions of …

Conceptualizations Of Data Visualization Use Beyond Efficiency In Evaluation, Sarah Douville

CGU Theses & Dissertations

Data visualization (data viz) is a valuable tool within evaluation for its ability to aid cognitive efficiency over text-based presentation of data (Card et. al., 1999; Evergreen, 2017, 2018; Few, 2012; Nussbaumer Knaflic, 2015; Tufte 2001). This exploratory multi-phase mixed methods research study considers purposes for using data viz in evaluation that can be achieved with that increased efficiency through the research question: “What conceptualizations of data viz use do program evaluators have beyond increased efficiency?”

In Phase I, secondary analysis of existing interview data with experts in both data viz and evaluation was used to better understand conceptualizations of …

Reaching Across The Divide: Tools For Bridging Structural And Viral Genomics Using A Combination Of Biophysical Principles And Machine Learning, Diana Yvette Lee

CGU Theses & Dissertations

Bacteriophages are the most ubiquitous biological entity on the planet, but most viruses found in nature cannot be cultured in the laboratory and encode genes whose sequences lack similarity with current nucleotide and protein databases. New predictive methods are thus necessary to determine the phenotype of viruses. In this work, we leverage the physical geometrical constraints of viruses to quantify the correlation between the geometric and genomic characteristics of tailed phages, and predict physical features such as architecture and genome length of uncultured viruses using allometric models and machine learning algorithms. Here, we present a model to predict the T-number …
