Genetic And Seasonal Contributions To Variability In Vitamin D Levels Among American Indians, Jack W. Staples, Erica L. Woodahl, Erin E. Ellerbeck, Rachel Dalton, Kathleen M. George, Genevieve Krause, Tianna Leitch, Kenneth E. Thummel, Leeanna I. Muzquiz, Matthew G. Mcdonald, Deborah A. Nickerson

UM Graduate Student Research Conference (GradCon)

Purpose: Vitamin D is an essential hormone in maintenance of calcium and phosphate homeostasis for adequate bone mineralization with roles in the immune system as well. Sources of vitamin D include natural synthesis in the skin upon ultraviolet B (UVB) radiation, dietary intake from plant and animal sources, and supplementation. Vitamin D levels, measured by the primary circulating vitamin D metabolite, 25-hydroxyvitamin D (25(OH)D), are variable across individuals due to latitude, season, diet, gender, disease states, medication use, and genetics. Populations living at northern latitudes (~40⁰N) such as American Indians of the Confederated Salish and Kootenai Tribes (CSKT) …

A Wolf In Fox’S Clothing? Using Stable Isotopes To Quantify Ecological Replacement, Tyler James Clark

UM Graduate Student Research Conference (GradCon)

During the Anthropocene, human-induced extinctions, especially of large predators and herbivores, have resulted in catastrophic ecosystem collapses. Recently, conservation tools such as rewilding (e.g., re-introducing a species to its native habitat) have been used to mitigate the effects of extinction. Another increasingly popular conservation tool, ecological replacement, proposes to introduce functionally similar, non-native species to fill the ecological roles of extinct, native species, thereby restoring ecosystems towards their pre-Anthropocene state. For example, the non-native Aldabra giant tortoise was introduced to the Mauritian island of Ile aux Aigrettes to replace the ecological role of extinct Cylindraspis giant tortoises. However, the …

Are Robots Morally Culpable? The Role Of Intentionality And Anthropomorphism, Sarah Sweezy, Shailee Woodard

UM Graduate Student Research Conference (GradCon)

Culpability for one’s actions arguably hinges on their intentions: A negative outcome is judged more harshly when done purposely versus accidentally (Zelazo, Helwig, & Lau, 1996). However, do children similarly apply this rule to a robot? And is this affected by their propensity to anthropomorphize? To investigate these questions, we tested 3- and 5-year-olds’ inferences of intentions and culpability of two agents (human and robot) and whether their judgments were influenced by their general tendency to anthropomorphize.

Participants (current N=63; 46% female) in two age groups (3 years: n=32, M=3.60 years, SD=.58; 5 years: n=31, …

Cognitive Reserve And Sex Differences In An Alzheimer's Disease Population, Emily Hicks, Genna Mashinchi, Hannes Heppner

UM Graduate Student Research Conference (GradCon)

Objective: The rate of cognitive decline is not equivalent for all AD patients, as some are able to remain functionally independent longer than others despite similar levels of neuropathology. Cognitive reserve theory (CR) posits that some people maintain cognitive functioning due to the presence of protective factors, such as educational and occupational attainment. The present study sought to investigate relations between cognitive functioning and education within an AD sample. Additionally, the current study examined if the impact of education was influenced by participant age and sex, as previous research has noted higher rates of AD in women than men.

Coordination Of Transboundary Marine Protected Areas In The Sulu-Sulawesi Seascape, Lindsey Ellett

UM Graduate Student Research Conference (GradCon)

Transboundary protected areas consist of clearly defined protected areas which are connected across one or more international boundaries and involve cooperation between multiple countries. The number of transboundary protected areas has experienced a dramatic increase in recent decades, and there are currently over 200 transboundary conservation initiatives worldwide. However, relatively few transboundary protected areas have been established for marine environments. Transboundary conservation approaches are integral to managing marine areas due to migratory species and issues like marine pollution and over-exploitation often crossing political boundaries. The development of transboundary marine protected areas (TBMPAs) may strengthen management and conservation by facilitating increased …

Who, Me? Yes, You!- Consultation And Collaboration In The Museum As A Form Of Crisis Remediation, Micaela E. Connolly

UM Graduate Student Research Conference (GradCon)

Museums face what has been named the “curation crisis” in a variety of manners. The crisis itself ranges from lack of personnel, funding, depleted storage space, etcetera. The question then presents itself, how do we, as museum professionals, remediate the effects of the curation crisis and prevent it from growing and occurring in new institutions. One such manner must include an increased level of consultation between museum personnel and outside sources. Here, I analyze the uses of consultation in the museum setting, ranging types of museums, and the benefits that may or may not occur in remediation efforts using this …

Public Places, Intimate Spaces: An Archaeology Of Prostitution In Missoula, Montana, Kate Gonzales

UM Graduate Student Research Conference (GradCon)

My research examines artifacts recovered from Cranky Sam Public House (CSPH), a brewery located in downtown Missoula where, in the summer of 2019, construction uncovered a significant amount of archaeological evidence related to Missoula's historic red-light district and Chinese community. This red-light district began operating in the late nineteenth century and continued to grow significantly until its closure in 1916. While many perceptions of early sex workers in American West towns focus on the vice activity associated with their employment, I hope to shift toward a narrative that provides alternative perspectives of these diverse women's lives. My thesis questions how …

Understanding Students’ Immediacies And Integrative Arguments In Collaborative Reasoning Discussions, Rebekah Skoog, Sisilia Kusumaningsih

UM Graduate Student Research Conference (GradCon)

Collaborative Reasoning (CR) discussion, as a form of a dialogic learning, has been proven to enhance children’s reasoning skills (Clark et al., 2003; Nguyen-Jahiel, et al., 2007; Sun et al. 2015). In CR, students are presented with a story that contains controversial issues and are asked to present evidence to support their stance towards the issue. In addressing the main question in CR, children challenge their peers’ arguments and encounter cognitive conflicts, which facilitate the development of their thinking to a higher level (Kim et al., 2007). This is significant as it can lead to discussants partially accepting the counterargument …

Leucine Carboxyl Methyltransferase 1 Overexpression Protects Against Cognitive And Electrophysiological Impairments In Tg2576 App Transgenic Mice, Madhumathi Gnanaprakash, Agnieszka Staniszewski, Hong Zhang, Rose Pitstick, Michael P. Kavanaugh, Ottavio Arancio, Russell E. Nicholls

Biomedical and Pharmaceutical Sciences Faculty Publications

Background: The serine/threonine protein phosphatase, PP2A, is thought to play a central role in the molecular pathogenesis of Alzheimer’s disease (AD), and the activity and substrate specificity of PP2A is regulated, in part, through methylation and demethylation of its catalytic subunit. Previously, we found that transgenic overexpression of the PP2A methyltransferase, LCMT-1, or the PP2A methylesterase, PME-1, altered the sensitivity of mice to impairments caused by acute exposure to synthetic oligomeric amyloid-β (Aβ).

Objective: Here we sought to test the possibility that these molecules also controlled sensitivity to impairments caused by chronically elevated levels of Aβ produced in vivo. …

Supplemental Ascorbate Diminishes Dna Damage Yet Depletes Glutathione And Increases Acute Liver Failure In A Mouse Model Of Hepatic Antioxidant System Disruption, Colin G. Miller, Jean A. Kundert, Justin R. Prigge, Julie A. Amato, Allison E. Perez, Lucia Coppo, Gabrielle N. Rizzo, Michael P. Kavanaugh, David J. Orlicky, Colin T. Shearn, Edward E. Schmidt

Biomedical and Pharmaceutical Sciences Faculty Publications

Cellular oxidants are primarily managed by the thioredoxin reductase-1 (TrxR1)- and glutathione reductase (Gsr)-driven antioxidant systems. In mice having hepatocyte-specific codisruption of TrxR1 and Gsr (TrxR1/Gsr-null livers), methionine catabolism sustains hepatic levels of reduced glutathione (GSH). Although most mice with TrxR1/Gsr-null livers exhibit long-term survival, ~25% die from spontaneous liver failure between 4- and 7-weeks of age. Here we tested whether liver failure was ameliorated by ascorbate supplementation. Following ascorbate, dehydroascorbate, or mock treatment, we assessed survival, liver histology, or hepatic redox markers including GSH and GSSG, redox enzyme activities, and oxidative damage markers. Unexpectedly, rather than providing protection, ascorbate …

Energy Islands: Metaphors Of Power, Extractivism, And Justice In Puerto Rico, Catalina M. De Onís

University of Montana Staff Publications

Energy Islands provides an urgent and nuanced portrait of collective action that resists racial capitalism, colonialism, and climate disruption. Weaving together historical and ethnographic research, Catalina M. de Onís challenges the master narratives of Puerto Rico as a tourist destination and site of “natural” disasters. She demonstrates how fossil-fuel economies are inextricably entwined with colonial practices and policies and how local community groups in Puerto Rico have struggled against energy coloniality and energy privilege to mobilize and transform power from the ground up. This work decenters continental contexts and deconstructs damaging hierarchies that devalue and exploit disenfranchised rural, coastal communities. …

Gozen In The Kindergarten Co-Teach Classroom, Suzanne Johnstone

Graduate Student Theses, Dissertations, & Professional Papers

This study analyzes the relationship between social emotional regulation and the program entitled GoZen!, for ten Kindergarteners in a Montana School over the course of a consistent nineteen weeks. To do this, a group of ten Kindergarten students’ behaviors were observed to compare the baseline number of visible self-regulation strategies to that following the initial modules, as well as following the entire GoZen! program. The data showed great promise with a 75% reduction in physical disruptions, an 85% reduction in harmful disruptions and a 18% reduction in verbal disruptions. The program used consisted of watching two-hundred and four short cartoon …

Beside| |Between, Brooke J. Armstrong

Graduate Student Theses, Dissertations, & Professional Papers

Beauty and the grotesque both induce physical sensations in the body. Pleasure and displeasure are two points on the same line. They are not mutually exclusive. Like the body and the vessel, like the self and the other all things exist in reciprocity. The capability of holding brings agency, breaking down perceptions of of subject-object relationships. The works presented in this paper represent a merging and a transformation of perceived separate entities. Craft history and processes inform the work present in the thesis exhibition, Beside| |Between.

Reading The Bones: A Taphonomic Investigation Of Archaeofaunal Remains Recovered From Site 48pa551, Northwest Wyoming, Morgan H. Thurman

Graduate Student Theses, Dissertations, & Professional Papers

This is a preliminary taphonomy study of archaeofaunal remains found at site 48PA551, more commonly known as the Dead Indian Creek Site. 48PA551 is a well-known and commonly cited example of a McKean Complex occupation dating to between 3,800 and 4,800 B.P. The University of Montana held a field school at the site conducting small test excavations under the supervision of Dr. Anna Marie Prentiss in 2018. In the course of this testing a highly fragmentary bone bed consisting mostly of mammalian bone, cervids largely, was discovered eroding into the nearby creek. Ten 50 x 50 cm quadrants were excavated …

The Ecology Of Puha: Identity, Orientation, And Shifting Perceptions Reflected Through Material Culture And Socioreligious Practice, Aaron Robert Atencio

Graduate Student Theses, Dissertations, & Professional Papers

This dissertation explores the assertions that changes in form, function, practice, and perceptions of puha primarily arose from the dispossession of landscapes and oppression of specific religious practices due to Euro-American contact, resource depletion, and reservation confinement. The reservation era placed the indigenous populace into a state of purgatory where treaties and peace relations were consistently repositioned and reneged. The perceptions of the indigenous inhabitants pre and post Euro-American contact detail critical moments that assisted in shaping the dynamic relationship between socioreligious perceptions and the Eastern Shoshone’s identity. What is displayed is a unique set of circumstances that assisted in …

Links Between Interspecific Competition And Infectious Disease: A Mechanistic Investigation With A Directly-Transmitted Zoonotic System, Andreas Elefttheriou

Graduate Student Theses, Dissertations, & Professional Papers

Globally, biodiversity is declining while emerging infectious diseases are on the rise. To explain this pattern, the “dilution effect” hypothesis predicts that with lower diversity, disease increases, because diversity “dilutes” disease. Although there is strong support for this hypothesis, there is evidence to support the “amplification effect” hypothesis, which predicts lower disease with lower diversity. Recently, there has been a push to investigate underlying mechanisms than general patterns to create a more mechanistic framework across disease systems. However, mechanisms have been mostly examined with indirectly-transmitted disease systems (e.g., Lyme disease), while less attention has been directed towards directly-transmitted systems, such …

Buffalo In The Mountains: Mapping Evidence Of Historical Bison Prescence And Bison Hunting In Glacier National Park, Kyle Langley

Graduate Student Theses, Dissertations, & Professional Papers

This study explores 10,000+ years of bison presence and bison hunting within Glacier National Park. Despite significant faunal evidence of bison presence in the area, few people today associate bison with Glacier National Park. Previous archaeological studies have found bison faunal remains and evidence of bison hunting throughout the eastern half of the park going back thousands of years. Furthermore, local tribes such as the Kootenai and Blackfeet maintain oral traditions that detail ancestral hunting strategies and practice in the region. This project reviews all of these sources to contextualize the archaeological signatures of bison and tell the story of …

Exploring Indigenous Involvement In The Fur Trade At The Bridge River Pithouse Village, British Columbia, Rebekah Jean Engelland

Graduate Student Theses, Dissertations, & Professional Papers

Much research has been done on the Fur Trade period occupation of Housepit 54 at the Bridge River site. This thesis investigates the cause of resource intensification seen in the increase in projectile points, faunal remains, hide scrapers, and fire-cracked rock (FCR). In order to determine the impetus of this change, I compare the fracture patterns of FCR, the size of FCR, the densities of FCR, deer NISP, and slate scrapers, and the population estimate from the fur trade floor and roof to the last floor and roof of the previous occupation. This will determine whether the resource intensification was …

Mapping Ethnophysiographies: An Investigation Of Toponyms And Land Cover Of Missoula County, Montana, Emily L. Cahoon

Graduate Student Theses, Dissertations, & Professional Papers

This thesis investigates the ethnophysiography of Missoula County, Montana via place names. Toponyms and landscape have been observed to have a relationship that can be studied through many lenses. Ethnophysiography, the study of how language and landscape relate to each other via human conceptualization, is a lens that was applied to this thesis because it recognizes the embodied information that toponyms carry and investigates landscape accordingly. Thus, the following research seeks to understand if ethnophysiographic diversity exists between toponyms in the Salish and English languages of Missoula County, Montana by analyzing place names and land cover in GIS and analyzing …
