Restoration Is Repairing Relationships: Bridging Indigenous And Western Sciences To Assess The Socio-Ecological Restoration Of Wild Rice (Zizania Palustris) On Keweenaw Bay Indian Community Homelands, Cassandra M. Reed-Vandam

Dissertations, Master's Theses and Master's Reports

Manoomin (wild rice, Zizania palustris) is an ecologically and culturally significant plant relative for the Keweenaw Bay Indian Community (KBIC). Historically, manoomin was present across much of the Great Lakes, however, their presence has declined since the early 1900s and, by 1990, virtually disappeared within KBIC homelands. Employing ethnography, surveys, focus groups, and conversations with Ojibwa knowledge holders, this research defined successful manoomin restoration for KBIC and developed socio-ecological attributes and indicators to assess restoration presented in the Medicine Wheel Framework for Manoomin Restoration. Surface water, sediment, and pore water samples at six different manoomin sites were analyzed to …

Hydrologic Pathways Of A Northern Hardwood Catchment In The Great Lakes Basin Using End Member Mixing Analysis, Cory C. Burkwald

Dissertations, Master's Theses and Master's Reports

This study investigated the seasonality of hydrologic pathways, the role of wetlands in streamflow generation, and how hydrologic pathways affect the export of nutrients by streamflow in the Sturgeon River using endmember mixing analysis. The results indicated that streamflow consists of three main components: shallow subsurface water from wetland soils, shallow groundwater, and surface runoff from precipitation. Snowmelt plays a dominating role in regulating stream water chemistry (~80% volume at peak) during the snowmelt season and likely also after that. Wetland soils store snowmelt, together with rainwater though the fraction is unknown, and then gradually release through summer in the …

Sediment Carbon Storage In Subtidal Beds Of The Invasive Seagrass Halophila Stipulacea Along An Extreme Water Depth Gradient, St. Thomas, U.S. Virgin Islands, Demian A. Willette, Kelsey M. Vaughn, Allie Durdall, Marilyn Brandt, Sophia Costa, Kristin Wilson Grimes

Biology Faculty Works

Blue carbon ecosystems such as mangroves, salt marshes, and seagrass beds are found globally and are fundamental to fisheries production, storm surge protection, and carbon sequestration. The contribution of seagrass ecosystems to global carbon stocks is still not well understood, including in the United States Virgin Islands (USVI). No study has been published to-date assessing the sediment carbon density (SCD) in seagrass beds in the USVI. This study focused on the carbon storage ability of the invasive species, Halophila stipulacea, which is compact in size compared to common native seagrasses and has spread rapidly to become a dominant seagrass in …

Geographies Of Storage, Sayd Randle

Research Collection College of Integrative Studies

Resource storage has long played a key role in the production of socio-ecological arrangements and economic relations. Even so, storage as a concept has remained somewhat marginal within geographical scholarship, often obscured by an analytical focus on the dynamics of movement. Reviewing recent works from geography, science and technology studies, and anthropology that center sites and practices of storage, this essay elaborates the diverse ways in which storage arrangements mediate resource circulation and the production of space. This literature demonstrates that thinking systematically with storage can illuminate a range of novel temporal, material, and value entanglements in-the-making, pointing to potentially …

Developing Resources To Foster Farmed Animal Agency In Sanctuary Education, Emily Tronetti

Antioch University Dissertations & Theses

Farmed animal sanctuaries provide lifelong care to formerly farmed animals. Many strive to educate their community about farmed animals and promote more compassionate lifestyles, such as veganism. Important to this is cultivating empathy and concern for the well-being of individual farmed animals. Essential to well-being is agency, which is the capacity of a living being to engage with their environments and to make choices for themselves. Farmed animals outside of sanctuaries have had their agency systematically suppressed and denied. Sanctuary educators can bring awareness to this and inspire alternative, agency-centered relationships with not only farmed animals but all living beings. …

Univariate Extreme Value Analysis Of Quantitative Investment Management, George Agbenyega Zumanu

Graduate Research Theses & Dissertations

The evolution of product development within the variable annuity (VA) business have sparked interest in quantitative investment management, particularly as most VA issuers have integrated volatility-controlled funds into their annuity portfolios. Despite the existence of empirical research on statistical analysis of extreme values in conventional investments, there has been a notable gap in research focus towards risk modeling in volatility-controlled funds.

This study contributes by analyzing and modeling the extreme values of investments in volatility-controlled funds, comparing them to conventional equity funds. The financial returns of S&P Dow Jones Indices (SPDJI) indices - SPXTR, risk control SPXT18UT, and managed risk …

Assessment Of Potential Impacts Of Climate Change On Hydrology And Water Resource Availability In The Passaic River Basin, New Jersey, Felix Oteng Mensah

Theses, Dissertations and Culminating Projects

Streamflow dynamics in a basin is known to be a major driver of available water resources. In the context of climate change, it is expected that global warming will accelerate the global hydrologic cycle, which will drive more intense floods and droughts leading to changes in streamflow and water resource availability. Most researchers agree that the amount and intensity of precipitation have a direct impact on runoff. Yet, there is no consensus as to how warming can affect streamflow. Evapotranspiration (ET) plays a crucial role here. However, there is a shortage of real-world observations on it. And yet, ET is …

Fostering Entry Level Practitioner Knowledge, Confidence, And Competence In Trauma-Informed Care Application, Mollie Keyser, Mary A. Barnes

Journal of Occupational Therapy Education

Trauma is pervasive worldwide and is associated with poor health outcomes if left unaddressed, however, a gap in practice continues to exist in the implementation of trauma-informed care (TIC). Occupational therapy practitioners will encounter individuals, communities, and populations influenced by trauma, which warrants the need for TIC to improve overall service delivery across the lifespan. However, TIC is currently not systematically integrated into any Accreditation Council for Occupational Therapy Education (ACOTE) occupational therapy educational standards. The purpose of this study was to design, implement, and evaluate a TIC application-based workshop for a sample of entry-level occupational therapy doctorate (OTD) students. …

How Does A Global Climate Cycle Affect The Reproductive Output Of A Neotropical Migratory Bird?, Abby K. Bressette, Emma Cummings, Daniel Albrecht-Mallinger, Lesley Bulluck

Undergraduate Research Posters

El-Niño Southern Oscillation (ENSO) causes regional changes in climate and has been found to have varying effects on the survival, fecundity, and recruitment of migratory songbirds. This study seeks to better understand the effect of ENSO on the fecundity of Virginia-breeding Prothonotary warbler (Protonotaria citrea; PROW), a neotropical migratory songbird. PROW breed in the Eastern United States and spend the non-breeding season primarily in Panama and Colombia. Ongoing research in Virginia has found a positive relationship between spring precipitation and predicted number of PROW fledgelings during La Niña, but the opposite during El Niño. To better understand this relationship, we …

Effective Land Use Classification Through Hybrid Transformer Using Remote Sensing Imagery, Muhammad Zia Ur Rehman, Syed Mohammed Shamsul Islam, Anwaar Ulhaq, David Blake, Naeem Janjua

Research outputs 2022 to 2026

Recent advances in deep learning for hyperspectral image (HSI) classification have shown exceptional performance in resource management and environmental planning through land use classification. Despite these successes, challenges continue to persist in land use classification due to the complex topology of natural and man-made structures. The uneven distribution of land cover introduces spectral-spatial variability, causing inter- and intra-class similarity. To address this issue, this study adopts a hybrid approach that combines convolutional neural networks (CNNs) and a transformer model. The technique comprises three key components: a spectral-spatial convolutional module (SSCM), a spatial attention module (SAM), and a transformer module. Each …

Trace And Rare Earth Elements Analysis Of Oligocene And Miocene Diamictites In The Cape Roberts Project, Ross Sea, Antarctica, Celina Flores Garza

Theses, Dissertations and Culminating Projects

The West Antarctic Ice Sheet is a major contributor to global sea level rise, yet its origin and dynamics are poorly known. The geochemistry of 35 diamictite samples from the CRP-1 and CPR-2A cores recovered by the Cape Roberts Drilling Project in the Ross Sea, Antarctica is evaluated to understand glacial sedimentation and flow paths during the Oligocene and Miocene, a period of warmer than present climate in the past. The major hypothesis to be tested is if the early Miocene ice sheet advance was the first major West Antarctic ice advance in the Ross Sea. The provenance of older …

Predicting Radiation-Induced Immune Suppression In Lung Cancer Patients Treated With Stereotactic Body Radiation Therapy, Jonathan Colen, Cam Nguyen, Seth W. Liyanage, Eric Aliotta, Joe Chen, Clayton Alonso, Kara Romano, Sean Peach, Timothy Showalter, Paul Read, James Larner, Krishni Wijesooriya

Data Science Faculty Publications

BACKGROUND: Stereotactic body radiation therapy (SBRT) is known to modulate the immune system and contribute to the generation of anti-tumor T cells and stimulate T cell infiltration into tumors. Radiation-induced immune suppression (RIIS) is a side effect of radiation therapy that can decrease immunological function by killing naive T cells as well as SBRT-induced newly created effector T cells, suppressing the immune response to tumors and increasing susceptibility to infections.

PURPOSE: RIIS varies substantially among patients and it is currently unclear what drives this variability. Models that can accurately predict RIIS in near real time based on treatment plan characteristics …
