Beyond The Belloni Decision: Sohappy V. Smith And The Modern Era Of Tribal Treaty Rights, Monte Mills

Articles

Indian tribes and their members are leading a revived political, legal, and social movement to protect the nation’s natural resources. In doing so, tribes and their allies employ many effective strategies but core to the movement are the historic promises made to tribes by the United States through treaties. Tribes are asserting treaty-protected rights, which the United States Constitution upholds as the supreme law of the land, to defend the resources on which they and their ancestors have relied for generations. Those claims have resulted in significant legal victories, igniting a broader movement in favor of tribal sovereignty and securing …

Police Officer Trauma In Rural Minnesota: A Narrative Study, John J. Littlewolf

Antioch University Dissertations & Theses

We call on police officers to respond to all of society’s tragedies. Whether in our metropolitan areas or our rural communities, law enforcement will respond when called upon. The culture of law enforcement is laden with traits of masculinity. These cultural traits can inhibit the processing of traumatic experiences in the individual. While the nature of law enforcement has remained the same, our scientific knowledge regarding trauma has grown. Trauma has a biological impact which can manifest as stress symptomology or PTSD. Our systematic response to trauma in law enforcement has not kept pace with the body of knowledge on …

Latinx Diversity Officers In Higher Education: Capacitating Cultural Values As Champions Of Equity, Diversity, And Inclusion, Maria Teresa Chavez-Haroldson

Antioch University Dissertations & Theses

The purpose of this research study is to share scholarly data that may assist in the recognition and cultural understanding of LatinX Chief DOs in higher education institutions. This multi-phase, qualitative study critically considers the participants’ sociopolitical, psychological, and, cultural situated-ness as equity, diversity, and inclusion (EDI) leaders in higher education institutions (HEIs). Despite the psychological stressors, the participants described how and why they are energized by their commitment to creating change as social justice campeonas (champions). This study explains why LatinX DOs leading EDI institutional change in the 21st century, places them in precarious sociopolitical circumstances. Cultural values are …

A Pedagogy Of Hope: Levers Of Change In Transformative Place-Based Learning Systems, Michelle G. Heaton

Antioch University Dissertations & Theses

In response to mounting wicked environmental problems and an outdated U.S. educational system, this dissertation investigates transformative place-based education as an adaptive boundary system that connects individual learning to positive social-ecological change. The research approaches learning through a systems lens through a novel framework of Social-ecological Systems, Place-based Education, and Transformative Learning Theories. A three-part mixed methods approach, including content analysis of the literature, phenomenological interviews with experts in place-based education, and fuzzy-logic cognitive mapping with educators at three schools practicing the principles of place-based education, is used to examine transformative place-based education from the perspectives of current U.S. place-based …

Developing An Odonate-Based Index For Monitoring Freshwater Ecosystems In Rwanda: Towards Linking Policy To Practice Through Integrated And Adaptive Management, Erasme Uyizeye

Antioch University Dissertations & Theses

Worldwide, the decline of biodiversity in freshwater ecosystems is occurring at an alarming rate, due to anthropogenic threats, which directly impact humans in a variety of ways. Freshwater ecosystems occupy an integral part of political, socio-economic and ecological spheres. Integrated Watershed Management (IWM) and Adaptive Management (AM) conceptual frameworks provide an underpinning holistic platform from which to evaluate the performance of policies and actions on the ground in relation to freshwater ecosystem management. I investigate the extent to which environmental policies and practices embrace IWM and AM frameworks in Rwanda. Furthermore, this dissertation develops an odonate-based ecological monitoring tool, referred …

Resource Selection And Calving Success Of Moose In Colorado, Forest P. Hayes

Graduate Student Theses, Dissertations, & Professional Papers

Across much of North America, moose populations (Alces alces) are declining due to disease, predation, climate, and anthropogenic pressures. Despite this, populations of moose in Colorado have continued to grow. Studying successful (i.e., persistent or growing) populations of moose can facilitate the continued conservation of the species by identifying habitat features critical for moose persistence.

First, I evaluated calving success of moose in Colorado and the impact of willow habitat quality and nutrition. I then estimated the probability of female moose having a calf using repeated observations in a Bayesian occupancy model. I assigned values for dry matter …

Generating Peptide Mass Spectrometry Ground Truth Data, Jessica L. Henning, Rob Smith

The software retains the first version’s capacity for loading, viewing, and navigating MS1 data in 2- and 3-D, and adds tools for capturing, editing, saving and viewing isotopic envelope and extracted isotopic chromatogram features. The software can also …

A New Classification System For Analyzing Burned Human Remains, Amanda Noel Williams

Graduate Student Theses, Dissertations, & Professional Papers

Fatal fires produce a range of physical alterations to the body that can be studied and analyzed to interpret perimortem events. Currently, the forensic community lacks a consistent, objective, and detailed scale to describe burn injuries or patterns in a variety of settings and conditions. There is a need to create a scale based on quantitative experimental data (e.g. duration and temperature of fire) that provides insight into the nature of the fire and cause of injuries contributing to the condition of the remains.

Observations from four main fire environments were used in developing a new classification system for analyzing …

Ethical Eating: Overcoming Alienation In The Industrial Food System By Aligning Our Practices With Our Principles, André Kushnir

Graduate Student Theses, Dissertations, & Professional Papers

This thesis arose out of a moment of discord, while an environmental philosopher was eating blackberries in the middle of a blizzard in Missoula, Montana. What follows is an attempt to bridge the gap between our principles and our practices, by asking the questions: What does ethical eating look like? Is it possible within our current industrial food system? and If not, what needs to change? Responding to the publication of the 2019 EAT-Lancet report, this essay moves beyond thinking of ethical eating as “healthy” and “sustainable” and challenges the networks of suffering and labour that we take for …

Alas, Poor Yorick: A Dna Analysis Of Ancestry Using Crania, Claire Hanson

Graduate Student Theses, Dissertations, & Professional Papers

Current methods for estimating ancestry in biological profiles provided to law enforcement and forensic collections rely heavily on the use of metric and non metric methods such as FORDISC 3.1 and “trait lists.” The reliance on these methods has led to inaccurate and ambiguous ancestry estimations, as many metric and non metric methods are subjective and cannot be statistically tested for error rates. As a result, forensic collections, such as the University of Montana Forensic Collection, could potentially house remains that have been inaccurately curated. In order to test the accuracy of curation in the UMFC, DNA samples were extracted …

Bird And Native Bee Responses To Habitat Treatments, Emily Bea Oja

Graduate Student Theses, Dissertations, & Professional Papers

As forests across the United States have been altered due to fire suppression in the last century, their structure has been altered, resulting in increased fuel loads. Subsequently, managers have been increasingly implementing habitat treatments including prescribed burning, mechanical thinning, and a combination of both treatments to reduce fuel loads and enhance habitat for ungulates. The Rocky Mountain Elk Foundation has partnered with agencies to complete over 10,000 of these treatments across the United States to enhance elk habitat. As treatment impacts to other wildlife species are not well understood, we evaluated the effects of these treatments on the bird …

Modeling Hydrologic Impacts Of Tribal Water Rights Quantification And Settlement On The Flathead Indian Irrigation Project, Jordan Andrew Jimmie

Graduate Student Theses, Dissertations, & Professional Papers

The Confederated Salish and Kootenai Tribes (CSKT) of the Flathead Reservation are a federally-recognized group of tribes (Kootenai, Salish, and Pend d’Oreille) located in western Montana. On the reservation lies the expansive Flathead Indian Irrigation Project (FIIP), which supplies irrigation water to approximately 127,000 acres of tribal and non-tribal agricultural land. The 1904 Flathead Allotment Act opened “surplus” land to non-native homesteaders without tribal consent, initiating the land ownership fragmentation observed on the reservation today. This legacy, combined with historically unquantified tribal reserved water rights and the antiquated state of the FIIP infrastructure, including water losses from unlined earthen canals, …

Acid Hydrolysis-Based Sugarcane Bagasse Biorefining For Levulinic Acid Production: Dynamic Mechanistic Modeling Under Varying Operating Conditions, Emília S. Lopes, Julio C.J. Gariboti, Luis H.Z. Feistel, Elmer Ccopa Rivera, Rubens Mac Iel Filho, Laura P. Tovar

Faculty Publications

© 2020, AIDIC Servizi S.r.l. The study on the lignocellulosic material conversion into bio-based platform chemicals, such as levulinic acid (LA), is one of the most promising routes to promote the development of advanced biorefineries. In this work, a dynamic mechanistic model is developed to simulate the LA production from lignocellulosic material. A wide operating range is used to estimate the parameters of the reaction kinetics. Because multi-parameter estimation problem is complex, a genetic algorithm-based optimization procedure is used to determine the optimum parameters values. Measurements are obtained for various reaction times (0 - 45 min) temperatures (150 - 200 …

The Covid-19 Vaccine Dilemma, Dorit R. Reiss

Faculty Scholarship

COVID-19 continues to lead to large numbers of deaths, harms, and financial costs. Without an effective vaccine, those will continue. The pressure to find a vaccine is high; and that pressure places a risk on the safeguards in place to assure that vaccines are safe and effective will be ignored. The United States has an extensive apparatus to oversee vaccine safety before and after licensing, including multiple federal committees and several monitoring systems, and that apparatus gave us, in 2020, an extraordinarily safe vaccine supply. This Article explains the different pressures that push for and against using the same apparatus …

The Prebiotic Provenance Of Semi-Aqueous Solvents, Jennifer L. Lago, Bradley T. Burcar, Nicholas V. Hud, Rio Febrian, Christopher A. Mehta, Paul J. Bracher, Zachary D. Atlas, Matthew A. Pasek

School of Geosciences Faculty and Staff Publications

The numerous and varied roles of phosphorylated organic molecules in biochemistry suggest they may have been important to the origin of life. The prominence of phosphorylated molecules presents a conundrum given that phosphorylation is a thermodynamically unfavorable, endergonic process in water, and most natural sources of phosphate are poorly soluble. We recently demonstrated that a semi-aqueous solvent consisting of urea, ammonium formate, and water (UAFW) supports the dissolution of phosphate and the phosphorylation of nucleosides. However, the prebiotic feasibility and robustness of the UAFW system are unclear. Here, we study the UAFW system as a medium in which phosphate minerals …

Eastern Equine Encephalitis virus (EEEV) is a virus found predominantly east of the Mississippi River in the United States that can be fatal to both equines and humans. The disease has previously been most prolific in states like Florida, but there has been an increase in the prevalence in other states further up north on the east coast of the United States in recent years. The purpose of this research is to use the ecological niche modelling program Maxent to model EEEV habitat suitability probability. This research utilized data of fatality incidence in equine hosts, versus sentinel chicken infection data, …

Optimizing Arbovirus Surveillance Using Risk Mapping And Coverage Modelling, Joni A. Downs, Mehrdad Vaziri, George Deskins, William Kellner, Kristi M. Miley, Thomas R. Unnasch

School of Geosciences Faculty and Staff Publications

Diseases carried by mosquitoes and other arthropods endanger human health globally. Though costly, surveillance efforts are vital for disease control and prevention This paper describes an approach for strategically configuring targeted disease surveillance sites across a study area. The methodology combines risk index mapping and spatial optimization modelling. The risk index is used to identify demand for surveillance, and the maximum covering location problem is used to select a specified number of candidate surveillance sites that covers the maximum amount of risk. The approach is demonstrated using a case study where optimal locations for sentinel surveillance sites are selected for …

A Hydrologic Landscapes Perspective On Groundwater Connectivity Of Depressional Wetlands, Brian P. Neff, Donald O. Rosenberry, Scott G. Leibowitz, Dave M. Mushet, Heather E. Golden, Mark C. Rains, J. R. Brooks, Charles R. Lane

School of Geosciences Faculty and Staff Publications

Research into processes governing the hydrologic connectivity of depressional wetlands has advanced rapidly in recent years. Nevertheless, a need persists for broadly applicable, non-site-specific guidance to facilitate further research. Here, we explicitly use the hydrologic landscapes theoretical framework to develop broadly applicable conceptual knowledge of depressional-wetland hydrologic connectivity. We used a numerical model to simulate the groundwater flow through five generic hydrologic landscapes. Next, we inserted depressional wetlands into the generic landscapes and repeated the modeling exercise. The results strongly characterize groundwater connectivity from uplands to lowlands as being predominantly indirect. Groundwater flowed from uplands and most of it was …

Codling Moth Mating Disruption, Marion Murray, Diane G. Alston

All Current Publications

Mating disruption became commercially available in the early 1990s, and was adopted by many Utah growers about a decade later. Use of this pest management technology can be daunting due to high up-front costs and monitoring requirements; however, after two to three seasons of use, the cost of mating disruption is the same or even less than conventional pest management.

Faulty Forensics: Bolstering Judicial Gatekeeping In Georgia Courts, Miranda S. Bidinger

Georgia Law Review

Forensic evidence is widely used in criminal cases
across the country and is accorded great weight by
juries. But critics have begun to question its reliability.
Its use has contributed to numerous wrongful
convictions, and though some individuals have been
exonerated, many remain incarcerated for crimes they
did not commit.
This Note explores a variety of forensic science
disciplines and their associated problems, the recent
push for forensic reform, and the current standards
governing the admissibility of forensic evidence at the
federal level and in Georgia courts, highlighting the
lenient standard embodied in the Georgia Code and

Hiv-Associated Neurocognitive Disorder (Hand) Biomarker Identification: Significance Analysis Of Microarrays And Two Persuasive Approaches With Random Forest, Hansapani Rodrigo, Bryan Martinez, Roberto De La Garza, Upal Roy

School of Mathematical & Statistical Sciences Faculty Publications

Background: HIV Associated Neurological Disorders (HAND) is relatively common among people with HIV-1 infection, even those taking combined antiretroviral treatment (cART). Genome-wide screening of transcription regulation in brain tissue helps in identifying substantial abnormalities present in patients’ gene transcripts and to discover possible biomarkers for HAND. This study explores the possibility of identifying differentially expressed (DE) genes, which can serve as potential biomarkers to detect HAND. In this study, we have investigated the gene expression levels of three subject groups with different impairment levels of HAND along with a control group in three distinct brain sectors: white matter, frontal cortex, …

Bayesian Modelling Of Nonlinear Poisson Regression With Artificial Neural Networks, Hansapani Rodrigo, Chris P. Tsokos

School of Mathematical & Statistical Sciences Faculty Publications

Modelling and prediction of count and rate responses have substantial usage in many fields, including health, finance, social, etc. Conventionally, linear Poisson regression models have been widely used to model these responses. However, the linearity assumption of the systematic component of linear Poisson regression models restricts their capability of handling complex data patterns. In this regard, it is important to develop nonlinear Poisson regression models to capture the inherent variability within the count data. In this study, we introduce a probabilistically driven nonlinear Poisson regression model with Bayesian artificial neural networks (ANN) to model count and rate data. This new …
