Gwayak Ateg Onaakonigewi Dibenjigewin: Decolonizing Jurisdiction In Anishinaabe Tribal Courts, Kekek Jason Stark

Nebraska Law Review

It is generally understood as a matter of federal Indian law that determinations of tribal law should properly be interpreted by tribal courts. This is because tribal courts do not always adhere to the same legal philosophy as their settler colonial counterparts. Many tribal courts subscribe to traditional law, which is an “essential source” of tribal jurisprudence. Anishinaabe communities have maintained a rich body of traditional tribal law since time immemorial. However, these customary law principles are only recently being included in modern-day Anishinaabe tribal court determinations. This Article builds upon the Anishinaabe law principles articulated in recent opinions and …

Estimation Of Probability Of Habitat Use Of Roosevelt Elk On The Olympic Peninsula, Vincent Michael Gugliotti

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Estimating the probability of habitat use for a particular species is crucial to the direct management and conservation of that species. Without knowledge of habitat preferences, managers cannot effectively focus efforts on vital resources or landscape types. However, modelling probability of habitat use can be done in several ways which leaves room for variation and uncertainty in the estimates produced by each method. This study is an examination of the variation between two estimates of probability of habitat use while focusing on a particular subspecies of elk that inhabits a unique ecosystem relative to other elk subspecies. I modeled elk …

Post-Fire Hydrologic Analysis: A Tale Of Two Severities, Kendra Fallon, Shawn J. Wheelock, Mojtaba Sadegh, Jennifer L. Pierce, James P. Mcnamara, Megan Cattau, Victor R. Baker

Civil Engineering Faculty Publications and Presentations

Addressing post-fire impacts largely depends on burn “severity.” A singular severity classification that encompasses the holistic effects of fire on all ecosystem processes does not currently exist. Lumping vegetation burn severity and soil burn severity into one metric, or using them interchangeably, can induce large inaccuracies and uncertainties in the intended ecosystem response to forcing. Often, burn “severity” reflects fire impacts on vegetation, which can be measured through remote sensing. Vegetation burn severity is likely more apropos for ecological research, whereas soil burn severity is more relevant for hydrological analyses. This paper reviews different remotely sensed vegetation severity products currently …

Reports On The Cost Of Administration Of Criminal Justice In Omaha And Lincoln, Nebraska, 1933: A Facsimile Edition & Contextual Casebook., Hattie Plum Williams, Michael R. Hill, Mary Jo Deegan

Zea E-Books Collection

The professional life of Hattie Plum Williams (1878–1963) epitomized the first generation of professional women sociologists on the Great Plains. At the University of Nebraska, she became the first woman in the world known to hold a regular appointment as chair of a coeducational, doctoral department of sociology (1923–1928). Often characterized as a social worker, her professional allegiance remained to sociology. Williams’ unsung labors in the early 1930s on behalf of the National Commission on Law Observance and Enforcement (NCLOE) resulted in two detailed, typewritten accounts of crime and criminal justice in Omaha and Lincoln, Nebraska. Her data collection, along …

Altitude And Pitch Control Of A Tethered Multi-Rotor Autogyro Using A Reduced Order Model, Tasnia Noboni

Graduate Thesis and Dissertation 2023-2024

Long-duration deployment of UAVs for surveillance and communication purposes can be very energy-consuming and expensive. Tethered autogyro-based UAVs can provide an energy-efficient solution to this problem and produce energy in the presence of a strong and persistent wind field at higher altitudes. Instead of using an engine, the unpowered autogyro rotors produce lift by creating an upward thrust force while relative airflow passes up through the rotor blades. The tether provides mooring action and can be used bidirectionally for transmitting or receiving power from the autogyro. Thus, tethered autogyros can address recent environmental concerns by reducing carbon footprint via efficient …

Developing Machine Learning Models For Selection Of Management Zones, Sravanthi Bachina

Electronic Theses and Dissertations

Soil sampling and analyses play a crucial role in optimizing nutrient management and enhancing crop productivity. However, collecting representative samples across diverse landscapes is challenging due to knowledge gaps about spatial variability of soil properties, large fields, multiple samples, and analysis costs. Collecting soil samples based on the management zones can help farmers gather precise information about soil properties with fewer samples. Recent developments in precision agriculture and machine learning. This study aimed to develop machine learning models that can learn, analyze, and refine landscape and soil properties data for automated selection of soil sampling zones and generating prediction maps. …

Local Social Capital, Disaster Housing Damage, And Mental Health: Insights From Hurricane Harvey, Ethan J. Raker, Kevin T. Smiley

Faculty Publications

Community-level social capital has been theorized to shape mental health, particularly in disaster contexts, but methodological complexities hamper prior studies. Pairing zip-code-level data on social capital from Opportunity Insights with repeated cross-sectional health survey data before and after Hurricane Harvey in Houston, Texas, we examine how local social capital moderated the mental health consequences of disaster housing damage. We first document null associations between local social capital and residents’ mental health before the disaster. Next, we fit models predicting psychological distress and poor mental health days, revealing that local levels of economic connectedness and rates of volunteering offset adverse mental …

Considerations And Applications Of Environmental Dna In Biodiversity Studies, Sarah Tomke

Theses and Dissertations--Forestry and Natural Resources

Environmental DNA (eDNA) sampling—the detection of species through genetic material shed into the environment—has become an efficient and reliable method for biodiversity assessments. The method has grown in popularity due to its non-invasive and non-destructive nature, and has revolutionized monitoring efforts for rare, elusive, and cryptic species for which traditional sampling approaches are often costly and ineffective. Hundreds of studies have utilized this technique to study species occupancy, delineate distributions, and assess relative community composition. Although eDNA sampling is an effective strategy for many conservation and ecological studies, recently, light has been shed on some of its potential drawbacks and …

Looking For Love On A Chilly Night: The Colorado Brown Tarantula Mating Season, Dallas Haselhuhn

Master's Theses and Doctoral Dissertations

Aphonopelma hentzi is the most widespread and abundant tarantula species in the United States. While a distinct mating season is observed, it has not been well studied and the environmental drivers for the mating season are unknown. By conducting daily surveys on a peripheral population within Southeast Colorado, between August and November 2022, I found that after the first significant temperature drop, the number of mate-seeking males was significantly higher than prior to this temperature event. Mate-seeking males were significantly correlated with a drop in the water vapor pressure gradient, a rarely used biological metric for assessing potential water loss …

Conserving water for irrigation of crops has become a concern in the dry zone of Sri Lanka due to changes in climate patterns. In response, the United Nations Development Program (UNDP) has developed climate-resilient water management projects designed to build climate-resilience and water management practices among farmers. One such program called ‘Wew Gam Pubuduwa’ disseminates climate smart home gardening techniques, where women farmers receive sprinkler and drip irrigation systems, seeds and fertilizers, as well as training on water management methods. This study draws on a feminist political ecology framework to analyze the experiences of women home gardeners who …

The Relationship Between Internet Addiction Test Scores And Academic Achievement, Michael L. Houston, John Foubert

Growth: The Journal of the Association for Christians in Student Development

The purpose of this study was to analyze the relationship between the Internet Addiction Test (IAT) score and academic performance in college students. The IAT measured the students’ addiction to the internet based upon their use. Academic performance was measured by grade point average (GPA). A sample of 692 traditional-aged college students from both public and private institutions was used to examine if IAT scores were related to and predictive of GPA. This study found a negative relationship between students’ IAT scores and GPAs. As IAT scores increased, students’ GPAs decreased. A better understanding of how internet addiction is related …

Occupancy Of The Little Grass Frog (Pseudacris Ocularis), An Overlooked Longleaf Endemic, In A Managed Landscape, Anna M. Humphrey

Theses, Dissertations and Capstones

Amphibians are declining globally, with many declines associated with habitat loss. The longleaf pine (Pinus palustris) ecosystem historically covered most of the southeastern United States and supports a host of endemic amphibians. This ecosystem has declined by over 97% in the last two hundred years and many associated species have declined with it. The Little Grass Frog (Pseudacris ocularis) is a longleaf pine endemic anuran that has been understudied and under-surveyed; almost no information is known on the ecology of this species and no population studies have been conducted. My goals were to create an acoustic …

Applied Soft Classes And Fuzzy Confusion In A Patchwork Semi-Arid Ecosystem: Stitching Together Classification Techniques To Preserve Ecologically-Meaningful Information, Josh Enterkine, T. Trevor Caughlin, Hamid Dashti, Nancy F. Glenn

Biology Faculty Publications and Presentations

Dryland ecosystems have complex vegetation communities, including subtle transitions between communities and heterogeneous coverage of key functional groups. This complexity challenges the capacity of remote sensing to represent land cover in a meaningful way. Many remote sensing methods to map vegetation in drylands simplify fractional cover into a small number of functional groups that may overlook key ecological communities. Here, we investigate a remote sensing process that further advances our understanding of the link between remote sensing and ecologic community types in drylands. We propose a method using k-means clustering to establish soft classes of vegetation cover communities from detailed …

An Aggregation Of The Pandalid Shrimp, Heterocarpus Ensifer, On Deep Reef Habitats Of The West Florida Slope, Eastern Gulf Of Mexico, Steve W. Ross

Gulf and Caribbean Research

Heterocarpus ensifer A. Milne—Edwards (1881) (Crustacea: Pandalidae), armed nylon shrimp, is widely distributed in the western and eastern North Atlantic Ocean. In the western Atlantic this shrimp occurs from off North Carolina to Brazil and in the Gulf of Mexico (GOM), western Bahamas, and Caribbean Sea at depths of 170—885 m. Despite its widespread occurrence, ecology or biology information for this species are sparse, and in situ observations of abundance, behavior and habitat preferences are particularly lacking. During extensive submersible and ROV observations on and near deep—reefs in the north—central and eastern GOM, a remarkably large aggregation of H. ensifer …

Assessment Of The Extraction And Quantification Of Pfbs From Sprague Dawley Rat Adipose Tissues, Joshua O. Osaghae

Honors College Theses

Per- and polyfluoroalkyl substances (PFAS) are a group of complex synthetic chemicals that have applications ranging from automotives to consumer products. PFAS have been found to bioaccumulate in the ecosystem as their carbon-fluorine bonds are among the strongest bonds in organic chemistry. Perfluorobutanesulfonic acid (PFBS) compounds are used as surfactants in water- and stain-repellent coatings for fabrics and carpets, cleaning agents, and paints. The persistence of PFAS has led to their accumulation in sources of groundwater, making them ubiquitous drinking water contaminants of concern with evidence linking PFAS exposure to adverse health effects, including reduced kidney function, thyroid disruption, and …

Environment And Belief: Investigating The Dakota Archeological Record, Anna Kay Wiitanen-Eggen

All Graduate Theses, Dissertations, and Other Capstone Projects

The oral traditions and histories of a people’s belief systems are one means by which the relationships between a people and their environment are embodied. Environmental aspects of a people’s belief system are reflected in their use of their habited space(s) because beliefs help structure actions. Ergo, an examination of a people’s oral traditions and histories has the potential to provide valuable insight to the archeological record of the places potentially occupied by their ancestors or close relatives. Investigation of this aspect of archeology is a relatively new pursuit and is almost completely unexplored in Minnesota. The relationship between the …

The Influence Of Natural And Anthropogenic Drivers On Estuarine Food Webs At Various Spatio-Temporal Scales And Levels Of Complexity, Michelle Shaffer

Graduate Thesis and Dissertation post-2024

Global coastal ecosystems support human life by providing critical services like food, water purification, and coastal protection, yet these ecosystems are among the most threatened due to natural and human-driven disturbances. The long-term maintenance and restoration of these ecosystems is a complex challenge for resource managers due to the wide range of factors affecting these ecosystems ecological condition over long timespans. Most studies in marine ecology evaluate ecosystem change over relatively short temporal scales (ago), often resulting in shifting baseline syndrome. To effectively manage and restore these ecosystems, resource managers must consider long-term ecosystem baselines.

From Redlining To Greenlining, Danielle Stokes

Law Faculty Publications

For generations, marginalized communities have been impacted by discriminatory land use, zoning, and property valuation policies, from redlining in the 1930s to the siting of undesirable land uses that persists today. Because of these policies, marginalized communities are forced to contend with low property values, substandard infrastructure, and increased health risks. The very same mechanisms that created these injustices, however, may now be key to addressing them. This Article introduces “greenlining” as a land use planning mechanism that seeks to remediate historical housing, siting, and economic disparities while forging a path toward energy and environmental justice. Greenlining, the productive and …

Identifying Nutrient Dynamics And Relative Groundwater Contribution In Wetlands At Fish Lake Environmental Center, Lapeer Mi, Rose Allen

Senior Honors Theses and Projects

Wetlands are complex ecosystems that are dependent on hydrologic processes and water chemistry. Understanding the role that water chemistry and nutrients play in wetland ecosystems is crucial to wetland management and restoration. The Fish Lake Environmental Education Center near Lapeer Michigan, is glacially influenced, and contains a large bog. Between the bog and lake there are multiple kettles that contain ephemeral wetlands in the spring. Bogs are primarily precipitation sourced, whereas the kettle wetlands may be a combination of precipitation and groundwater sourced. Previous studies indicated that groundwater flow direction is towards Fish Lake, but it was unclear to what …

Effects Of Timber Harvest On Understory Vegetation Succession: A Time Series Study, Reese A. Poindexter, Trevor Weeks, Chad Bishop, Akasha Faist

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Timber harvest, as a necessary and common global practice, can significantly affect the ecosystems being harvested through opening the canopy, disturbing the understory, and resetting successional trajectories. This study examined how timber harvest influenced understory plant functional group dominance, understory species richness, and understory species dominance along a 40-year, or older, harvest timeline across two forest types (mesic and xeric) in Northwestern Montana, U.S.A. In our two forest types, vegetation sampling was completed at 208 sites with 1,040 quadrats across six timber-harvest timelines. Harvest timelines varied from the most recent at 1-5 years post-harvest to over 40 years as the …
