Decoupled Diel Solutes: Linking Primary Production And Nitrate Uptake In A Montane Stream, Kimberly Bray

Graduate Student Theses, Dissertations, & Professional Papers

Tight coupling of surface water diel dissolved oxygen (DO) and nitrate-N (NO₃-N) signals reflects stoichiometric demand of carbon and nitrogen in stream ecosystems. However, DO and NO₃-N can become decoupled due to alternative drivers of diel solutes, resulting in conflicting estimates of stoichiometric and modeled NO₃-N uptake. In this study, I measured benthic biomass, hydrology, and dissolved solutes in a montane stream located in western MT over a growing season (June-October 2019). Daily stream metabolism and NO₃-N uptake were modeled using a single-station open-channel approach. Timing and amplitude of key diel signals …

Understanding Native American Hemp Production, Cynthia Marie Steckdaub Coleman

Graduate Student Theses, Dissertations, & Professional Papers

In this thesis, I take an in-depth look at Native American hemp production through the lens of three hemp projects. My research sits within the history of colonization and dispossession. I look at two tribal hemp projects and one individual Native American hemp farm and describe how each project reaches for tribal sovereignty through hemp production. I look at how hemp fits into tribal worldviews, cultures, and the relationship tribal farmers have with hemp. Focusing on key elements of relationship, like respect, reciprocity, and responsibility, I examine how hemp production can be incorporated into Indigenous communities. Beyond relationships with the …

Perceived Threat And Left-Wing Authoritarianism: The Effect Of Framing On Persuasive Messages, James Donald Mcfarland

Graduate Student Theses, Dissertations, & Professional Papers

Past research reveals a strong connection between feeling threatened and Right-Wing Authoritarianism (RWA). This relationship is considered to be an integral part of authoritarianism and the nature of its presence in the left-leaning populace is still being fully explored. This study examined the relationship between perceived threat and Left-Wing Authoritarianism (LWA) through the framing of persuasive messages. Participants (n = 256) were recruited through Amazon’s Mechanical Turk (MTurk) and given a list of reward- or threat-framed statements concerning the possible ramifications of voting in future elections and then asked to rate the quality and persuasiveness of the respective statements. …

Conceptions And Receptions: A Case Study Analysis Of Community Engagement At Four Local Museums, Mary L. Casey

Graduate Student Theses, Dissertations, & Professional Papers

The theme of community engagement has been a prevalent topic of debate and discussion among museum professionals across the country, and so this thesis seeks to examine how four local museums connect with their local audiences in meaningful and successful ways. I focus on local museums because they have the unique opportunity to intimately engage their immediate community’s perceptions of identity and heritage, and relate the interpreted past in innovative ways that effectively resonate with the contemporary lives of current residents.The Historical Museum at Fort Missoula, Strawbery Banke Museum, The Tuck Museum of Hampton History, and the James House Museum, …

Quantifying The Effects Of Non-Native Rainbow Trout (Oncohynchus Mykiss) Hybridization And Environmental Conditions On Fitnessrelated Traits Of Westslope Cutthroat Trout (Oncorhynchus Clarkii Lewisi), Jeffrey Thomas Strait

Graduate Student Theses, Dissertations, & Professional Papers

Human-mediated hybridization is a serious and growing threat to the conservation of biodiversity worldwide. Introgressive hybridization between introduced rainbow trout (Oncorhynchus mykiss, RBT) and westslope cutthroat trout (Oncorhynchus clarkii lewisi, WCT) is widespread across much of historical range of WCT and is considered one of the top threats to the persistence of remaining WCT populations. The ecological and evolutionary consequences of RBT hybridization and the role of environmental conditions in mediating those consequences is largely unknown but critical for making management decisions. I investigated three fitness-related traits across multiple populations to improve our understanding of the genetic basis of fitness …

Three-Dimensional Geometric Morphometric Sex Determination And Modeled Fragmentary Analysis Of The Human Pubic Bone, Katherine Scot Baca

Graduate Student Theses, Dissertations, & Professional Papers

Geometric morphometrics has become a more popular method in anthropology as three-dimensional data and research become more widely recognized and accessible. This research provides a refined method utilizing 3-D geometric morphometric analysis to determine sex from the human pubic bone. The study used a sample of N=378 individual pubic bones from the University of New Mexico Maxwell Documented Collection. Eight landmarks were digitized on each individual bone using a Microscribe Digitizer. Results from the Principal Components Analysis provide promising clustering between male and female groups, as well as indications that the method may be ancestry-specific, and that parity may have …

College Athletes And Alcohol Use: The Need For Effective Prevention/Intervention Programs, Paige M. Craig

Graduate Student Theses, Dissertations, & Professional Papers

The literature review investigates the relationship between alcohol and college athletes. College athletes are a high-risk drinking group; alcohol use amongst collegiate athletes is a major concern due to the consequences associated with use. It is important to review student-athlete behavior and influences that contribute to alcohol use in order to design a program that effectively prevents use and intervenes use when it occurs. Results from original articles were used to support the need for effective prevention/intervention programs for this population based on the severity and frequency of use, negative effects of alcohol, and lack of effective prevention/intervention programs. Coaches, …

Tending To The Tapestry: An Ecofeminist Interpretation Of Women Farmer-Artists' Stories, Aubrey Pongluelert

Graduate Student Theses, Dissertations, & Professional Papers

There is a disconnect in Western academia, between classroom conversations concerning the impact of environmental degradation on rural communities, and engagement with those communities whom we are discussing. Those working in environmental studies are confronted with the question of how to effectively communicate the concerns addressed by the field in ways which are accessible to, and engage broader audiences. Creative languages such as the visual arts, storytelling, and music are invaluable tools in this task because they offer accessible and culturally relevant means of conveying ideas, perspectives, and experiences. This project examines the ways in which these creative languages contribute …

Managing Forest Disturbances: Effects On Mule Deer And Plant Communities In Montana's Northern Forests, Teagan Ann Hayes

Graduate Student Theses, Dissertations, & Professional Papers

Mule deer (Odocoileus hemionus) are frequently the focus of population and habitat management in the western United States. Land and wildlife managers use disturbance to reset forests to earlier successional stages and improve the quality and quantity of forage available to mule deer. However, the effects of management practices on nutrition and selection vary widely, so the implementation of management practices raises ecological as well as management-related concerns. This work investigated how disturbance from wildfire, prescribed fire, and timber harvest influences the spatial and temporal distribution of nutritional resources in mule deer summer range, and therefore, how the …

Wonder: A Phenomenological Exploration, Henry R. Kramer

Graduate Student Theses, Dissertations, & Professional Papers

This paper presents a phenomenology of wonder through careful description of the internal state of wonder, defined here as “full engagement with something that bewilders you.” This phenomenology explores what is at stake in regards to our inhibitions toward wonder, how we can overcome those inhibitions, what the experience of wonder is like, and what effects wonder can have on our lives and ethical activity. This includes an investigation of the relationships between wonder and topics such as judgment, attention, engagement, imagination, play, and our ethical treatment of the more-than-human world. This paper demonstrates that by cultivating wonder we are …

Flowers From The Devil: An American Opiate Crisis, The Criminalization Of Marijuana, And The Triumph Of The Prohibition State, 1840-1940, Clinton David Lawson

Graduate Student Theses, Dissertations, & Professional Papers

This dissertation focuses on historic changes in public perception of narcotic use and abuse from the mid-nineteenth century to the mid-twentieth. From the 1840s to the outbreak of Civil War, politicians, physicians, the general public, and state and federal government remained largely ambivalent on the topic of drug use. Opium, morphine, and cannabis were legal, widely available in American pharmacies, and touted as essential medicines. Within the Bohemian community, artists and writers experimented with the recreational use of cannabis and their accounts of that style of consumption filled the pages of Harper’s, The New Yorker, and a host of other …

Fleshy Encounters: Meddling With Zoo And Aquarium Veterinarians, Irus Braverman

Journal Articles

This article aims to make visible expert practices that take place behind closed doors and that are perceived as being of no concern to the public, who wouldn’t understand them anyway. The experts that this article is concerned with are medical practitioners of a particular kind: zoo and aquarium veterinarians. I utilize both text and multimedia presentations to allow the veterinarians I interviewed to directly explain their work to the reader, who may then experience this work, the space and environment where it is performed, and the tools with which it is conducted, on a more affective and sensorial plane. …

Manuscripts, Articles, Book Chapters and Other Papers

OBJECTIVE: The SI gene encodes the sucrase-isomaltase enzyme, a disaccharidase expressed in the intestinal brush border. Hypomorphic SI variants cause recessive congenital sucrase-isomaltase deficiency (CSID) and related gastrointestinal (GI) symptoms. Among children presenting with chronic, idiopathic loose stools, we assessed the prevalence of CSID-associated SI variants relative to the general population and the relative GI symptom burden associated with SI genotype within the study population.

METHODS: A prospective study conducted at 18 centers enrolled 308 non-Hispanic white children ≤18 years old who were experiencing chronic, idiopathic, loose stools at least once per week for >4 weeks. Data on demographics, GI …

Rewilding Or Reviewing: Conservation And The Elephant-Based Tourism Industry, Ingrid Suter

Animal Sentience

Baker & Winkler (2020) provide a detailed examination of elephants in captivity, from an historical perspective to modern-day concerns. Concerns include the poor level of mahout skills and subsequent captive elephant welfare issues in the Thai elephant tourism industry. Rewilding is proposed as a method of rehabilitation and a way to include mahouts in the conservation process. This commentary argues that the tourism industry is making positive changes and mahout skills can be utilised successfully without the arduous task of rewilding. Animal rights groups and the transfer of misinformation surrounding captive elephant welfare are also examined, as these typically fail …

Physical Activity In Aging: Biological Outcomes, Functional Autonomy, And Policy Implications, Nathan Albert Schuler

Theses

A 2016 study concluded that the elderly spend 2.5 times the national average on health services (De Nardi 2016). Despite consisting of only 14 percent of the United States population, the elderly accounted for 34 percent of all medical spending, and accounted for 73 percent of all deaths (De Nardi 2016). In addition, current projections estimate that with the aging of the baby boomer generation, the percentage of the population that is older than 65 will swell to approximately 20 percent of the population by 2030 (Ortman 2014). If the medical spending holds, this will coincide with massive increases in …

Federalism As A Double-Edged Sword: The Slow Energy Transition In The United States, Roger Karapin

Publications and Research

Much literature on federalism and multi-level governance argues that federalist institutional arrangements promote renewable-energy policies. However, the U.S. case supports a different view, that federalism has ambivalent effects. Policy innovation has occurred at the state level and to some extent has led to policy adoption by other states and the federal government, but the extent is limited by the veto power of fossil-fuel interests that are rooted in many state governments and in Congress, buttressed by increasing Republican Party hostility to environmental and climate policy. This argument is supported by a detailed analysis of five periods of federal and state …

Improving Inverse Compton Sources By Avoiding Non-Linearities, B. Terzić, G. A. Krafft, V. Petrillo, I. Drebot, M. Ruijter

Physics Faculty Publications

We present a new, more nuanced understanding of non-linear effects in inverse Compton sources. Deleterious non-linear effects can arise even at low laser intensities, a regime previously viewed as linear. After laying out a survey of non-linear phenomena which degrade the effectiveness of inverse Compton sources, we discuss two powerful techniques designed to avoid these non-linearities. Starting with the known technique of non-linear longitudinal chirping of the laser pulse in the high laser field regime, we show that the simple stretching of the laser pulse, while keeping the energy constant, can significantly increase the spectral density of the scattered radiation …

Wearable Antennas Backed By Artificial Magnetic Conductor For Enhanced Gain And Reduced Back Radiation, Steven Jacobson

Theses

A Wireless Body Area Network (WBAN) is a system of wireless sensors and devices attached to a person’s body for continuous monitoring of physiological data. These measurements can be used for a variety of purposes such as fitness tracking, personal health management or as medical diagnostic tools. In many cases, WBANs need to communicate with an off-body device to send information to healthcare providers. Wireless Medical Telemetry provides numerous benefits but has a few challenges that need to be overcome. One of the key components in this system is the antenna, which is worn on the body and typically has …

Investigating The Effects Of Blood Flow On Muscle Fatigue And Recovery In The First Dorsal Interosseous Muscle, Nicole Nugent

Theses

The purpose of this study was to gain insight into the physiological principles driving blood flow and fatigue both during and following different levels of intermittent exertion. Utilizing diffuse correlation spectroscopy (DCS) allowed microvascular blood flow (BF) to be observed continuously, providing new insight into the behaviors of BF within the exerting muscle. This experiment was conducted with 11 healthy, adult participants, (5 male, 6 female), fatiguing the First Dorsal Interosseous (FDI) muscle through the abduction of the index finger. The study monitored BF and fatigue in response to 3 levels of intermittent exertion (20%, 30%, and 40% MVC) under …

Relationship Between Cognition And Moral Status Needs Overhaul, Carrie Figdor

Animal Sentience

I commend Mikhalevich & Powell for extending the discussion of cognition and its relation to moral status with their well researched and argued target article on invertebrate cognition. I have two small criticisms: that the scala naturae still retains its appeal to some in biology as well as psychology, and that drawing the line at invertebrates requires a bit more defense given the larger comparative cognitive-scientific context.

Affective Sentience And Moral Protection, Russell Powell, Irina Mikhalevich

Animal Sentience

We have structured our response according to five questions arising from the commentaries: (i) What is sentience? (ii) Is sentience a necessary or sufficient condition for moral standing? (iii) What methods should guide comparative cognitive research in general, and specifically in studying invertebrates? (iv) How should we balance scientific uncertainty and moral risk? (v) What practical strategies can help reduce biases and morally dismissive attitudes toward invertebrates?

The Necessity Of Human Attitude Change And Methods Of Avoiding Pandemics, Donald M. Broom

Animal Sentience

Humans share their biology with other animals and in each of their actions should consider the consequences for all life. A series of measures can be taken by governments and individuals that would minimise inter-specific transfer of pathogens from wildlife and reduce the development of antimicrobial resistance.

It Does Not Cost The Earth To Be Kind, Svetlana Feigin

Animal Sentience

The COVID-19 crisis is a wake-up call on a global scale. What lessons we learn from this crisis will determine our survival as a species. The global health crisis calls for individual and collective changes in our agricultural practices and our consumption habits. Most important, it is a call for us as a species to move towards an empathic way of living and interacting with nature.

Tribal Brains In The Global Village: Deeper Roots Of The Pandemic, Robert Gerlai

Animal Sentience

I briefly recap the messages of the target article by Wiebers & Feigin (2020) and the accompanying peer commentaries about what we learn from the COVID-19 pandemic. Using the rapid evolution of viruses as an example of the importance of prevention, I explore why it is difficult for our species to foresee and prevent unintended global changes resulting from human activity. I end with a discussion about the long-term future, the ultimate problem inherent in our current mindset and the structure of our economy: growth.

Feasibility Assessment Of Acid Mine Drainage And Municipal Wastewater Co-Treatment, Charles D. Spellman Jr.

Open Access Master's Theses

Acid mine drainage (AMD) and municipal wastewater (MWW) are two constituents that pose major environmental risks to surface waters if left untreated. Modern MWW treatment facilities are capable of removing organics and pathogens from wastewater before being discharged into surface waters. Although proven methods also exist for treating AMD, it is commonly untreated. Over the past few years, researchers have illuminated new approaches to simultaneously co-treat AMD and MWW. However, there is little research on combining the two waste streams within a conventional wastewater treatment plant for co-treatment. Co-treatment could facilitate metal removal from AMD while also improving MWW treatment …

Evolution Of A Subducted Carbon-Rich Filament On The Edge Of The North Atlantic Gyre, Alexis Johnson

Open Access Master's Theses

The oceanic biological carbon pump encompasses a variety of mechanisms by which CO2, fixed into organic form by phytoplankton, is transported from the sunlit surface layers to the interior ocean. Here, we investigate submesoscale and mixed layer subduction, the physical arm of the biological pump, estimated to represent approximately 20% of global organic carbon (POC) export. Seven biogeochemical Argo (BGC) profiling oats were analyzed for evidence of physical subduction of POC in the North Atlantic Ocean. While we do not yet have enough measurements to reveal basin wide spatial trends, a notable pattern is found in the seasonality, suggesting that …

The (En)Tangled Web They Weave: Stakeholder Perceptions Of The Large Whale Take Reduction Plan Process, Kimberly P. Ohnemus

Open Access Master's Theses

Negotiated rulemaking is a decision-making process that has been integrated into U.S. regulatory processes within the last three decades. Amendments to the Marine Mammal Protection Act in 1994 mandated the creation of Take Reduction Teams, stakeholder committees that use negotiated rulemaking to develop regulations to reduce marine mammal interactions with commercial fishing operations. The largest and least successful of these teams is the Atlantic Large Whale Take Reduction Team (ALWTRT), which is tasked with developing regulatory measures to protect the highly endangered North Atlantic right whale, as well as other large whale species. This study used semi-structured interviews with members …

Modeling Coral Reef Acoustic Propagation Loss, Kayla M. Thilges

Open Access Master's Theses

Quantification of an acoustic metric relating sound propagation on a coral reef to ecological parameters could enhance long-term ecological studies on coral reefs. The acoustic metric constructed in this study is coral reef propagation loss, or the sound intensity reduction with range, in a coral reef environment. Establishment of this benchmark parameterizes the geometric spreading and attenuation factors of the coral reef environment.

Two analyses are conducted in which both passive and active acoustics are used to measure the sound propagation environment across different fringing coral reef sites. In the first analysis, two passive acoustic studies in the literature captured …

Student Collaborations In Introductory Statistics Courses; A Network Study, Isabel S. Nowinowski

Open Access Master's Theses

Generation Z, also known as iGen, (individuals born between the mid-1990s and early 2010s), characterized as tech-savvy, independent, and visual, is beginning to graduate college and enter the workforce. While significant research effort has focused on understanding the learning preferences of the preceding Millennial generation (individuals born between the early 1980s and mid-1990s), less is known about the way technology has influenced the educational expectations and learning preferences of Generation Z. A deeper and broader understanding of the way this generation learns would allow universities to modify and enhance course structures and teaching methodologies to suit this incoming generation of …
