Effect Of Exercise In Children, Jessica L. Moler

Graduate Student Theses, Dissertations, & Professional Papers

Although the health benefits of exercise in adults are well established (Ruegsegger & Booth, 2017), the role of physical activity in promoting health in children is often overlooked. This narrative review synthesizes current research on the physical, cognitive, and emotional benefits of exercise in children aged 5 to 18, with a focus on providing practical, evidence-based guidance for families, educators, and healthcare providers. Studies consistently show that moderate-to-vigorous physical activity reduces cardiovascular and metabolic risk factors (Dias et al., 2017; Kovács et al., 2009; Migueles et al., 2023), improves insulin sensitivity (Bell et al., 2007; Davis et al., 2012), and …

Slaying The Windigo: Fear And Faith In The Anthropocene, Daniel J. Irwin

Graduate Student Theses, Dissertations, & Professional Papers

This thesis examines the changing affect of fear in the environment and how it is influencing writing in the Anthropocene. Chapter one lays the groundwork for the present moment of ecocriticism, examining how the relationship with the environment has changed throughout the history of ecocritical writing. The second chapter examines how fear has been an intrinsic element of environmental storytelling, starting with the romantic ideas of the sublime. With the recognition of the impact that humanity has had on Earth over the past several centuries, and the accelerating acceptance of the idea of the Anthropocene since the turn of the …

Social Connection And Disability: A Longitudinal Experimental Study Of Intervention Effectiveness And Moderators, Krys Standley

Graduate Student Theses, Dissertations, & Professional Papers

Background: Social disconnection is an epidemic-level problem that is exacerbated for people with disabilities. There is a pressing need for theory-based research to illuminate the factors that contribute to effective interventions for improving social connection in this population.

Objectives: The objectives of this study were 1) to test the hypothesis that the Peer Collective, a six-week, online, group-based intervention centered on social support topics, would result in increased levels of social connection among community-dwelling adults with any types of disabilities and 2) to examine potential moderating effects in this hypothesized relationship.

Method: A longitudinal intervention study design with random assignment …

On Creating Bog Bodies: The Effects Of Ph Value On Dna Decomposition In A Bog Environment, Gabrielle B. Giangreco

Graduate Student Theses, Dissertations, & Professional Papers

Bog bodies have been a consistent area of interest in both archaeology and biological anthropology, due to their high rates of physical preservation. While there are many physical analyses that have been done on these remains, DNA analysis is lacking. Most studies focus on changes to the remains themselves or attempt to determine why they were placed in a bog. This study aims to examine the effects of pH level on the breakdown of DNA on remains placed inside a bog along with any larger differences in the preservation of the remains. The results of this study seem to point …

Theory Of Planned Behavior And Suicide Screening In Family Medicine, Jennifer Villa

Graduate Student Theses, Dissertations, & Professional Papers

General medical healthcare settings, particularly primary care and family medicine practices, serve as critical access points for addressing mental health concerns. This is especially true in rural communities, where specialized behavioral health services are often limited or unavailable. Given the elevated suicide risk in these settings and the shortage of mental health professionals, primary care providers are well-positioned to identify patients at risk through suicide screening. However, research shows that many established providers do not routinely screen for suicide, representing a missed opportunity for prevention, and little is known about resident attitudes towards suicide screening and prevention. Guided by the …

Evaluating The Accuracy Of Stature Estimation From Tibial Radiographs Using Known And Newly Developed Regression Formulas, Atlantis Kae Baron

Graduate Student Theses, Dissertations, & Professional Papers

This study assesses the accuracy of stature estimation from tibial radiographs using digital measurements as an alternative to traditional osteometric tools. Stature estimation is crucial in forensic anthropology for identifying individuals, especially cases involving skeletal remains. Traditional methods rely on physical measurements and established regression formulas, such as those by Trotter & Gleser (1958).

This research analyzed tibial radiographs from the Forensic Anthropology Skeletal Trauma (FAST) database with ImageJ software to measure tibial lengths digitally. The sample included 59 tibiae, with measurements compared against three regression formulas; Trotter & Gleser (1958), Simon et al. (2023), and a new regression formula …

Juvenile Arthritis, Body Image, And Disordered Eating: An Exploration Of Experiences, Katelyn Ann Melcher

Graduate Student Theses, Dissertations, & Professional Papers

This qualitative study examined eating and body experiences among youth with juvenile arthritis (JA). JA, an autoimmune condition affecting nearly 300,000 youth in the United States, poses significant challenges including chronic pain, disability, and psychological concerns such as anxiety and depression. Adolescence is a critical developmental time for body image and disordered eating concerns to emerge. However, no qualitative research has explored the interactions of JA, body image, and eating behaviors among youth. Twelve youth with a JA diagnosis participated in a semistructured qualitative interview examining their experiences with JA and their feelings about their bodies and food as they …

College Athlete Workload Management To Improve Performance, Brody Reid

Graduate Student Theses, Dissertations, & Professional Papers

Load management is an often used and misunderstood term within the realm of sport science. It has been described as the reason behind numerous soft tissue injuries as well as being the reason star athletes sit on the bench for games. This review aims to synthesize the existing literature regarding the workload management paradox within sport. Seminal work in this topic has been gathered mostly by Tim Gabbett in the paper “The Injury Prevention Paradox” where a relationship between fitness gain and fatigue accrued is outlined. This theory was first proposed by Roger Bannister in 1975. This paper …

Love At First Words: A Communication Competency Approach To Romantic Relationship Initiation, Grace E. Wiegand

Graduate Student Theses, Dissertations, & Professional Papers

Initial interactions are essential to romantic relationship formation, and both parties must desire a second interaction after an initial encounter for the relationship to advance. Many studies have explored the communication styles and tactics that are effective in a person desiring a second interaction from a dating initiation scenario. However, existing research has yet to explain why some communication strategies do or do not result in second interactions. The current study seeks to examine this phenomenon further, testing the extent to which perceived partner communication competence influences a person to want to see another again after an initial interaction. In …

Testing The Hefner (2009) Ancestry/Population Affinity Estimation Method On Japanese Bioarchaeological Populations And Observing Changes In Trait Frequency Distribution Over Time, Tristan Charnock Hershberger

Graduate Student Theses, Dissertations, & Professional Papers

Population affinity is the most controversial aspect of the biological profile to assess for forensic anthropologists due to an array of factors, both historical and in application. This has led to many calls for the abandonment of this type of estimation, however, many have challenged this by arguing for the category’s importance in the death investigation process. While the abandonment of population affinity estimation is unlikely, that does not mean that current approaches to population assessment should not be reassessed. This study attempts to reevaluate the category by applying an evolutionary lens to population affinity assessment. This project applied a …

Utilization Of Sprint Interval Training In Intermittent Sports, Marcus David Garcia

Graduate Student Theses, Dissertations, & Professional Papers

Sprint interval training (SIT) is a powerful training method that involves short, maximal sprint efforts followed by brief recovery periods. This modality shares similar physical demands of intermittent sports, where athletes repeatedly transition between maximal exertion and submaximal efforts or rest. The purpose of this paper is to explore the impact of SIT on key performance metrics in intermittent sports, such as sprint speed, repeated sprint ability (RSA), aerobic capacity, and anaerobic power. SIT not only enhances anaerobic performance but also promotes adaptations like faster phosphocreatine resynthesis, increased glycolytic enzyme activity, and shifts in muscle fiber composition. These adaptations contribute …

The Devil In The Bakken, Kennedy Lorraine Delap

Graduate Student Theses, Dissertations, & Professional Papers

In 2008 the oil boom hit North Dakota. The oil brought wealth and human health concerns to the state and specifically, the Fort Berthold Indian Reservation. In July of 2024 the largest Clean Air Act Settlement of its kind happened on the reservation due to Marathon Oil emitting thousands of tons more pollutants that regulations outlined. This story dives into the human health effects, advocacy and the difficulty in balancing health and wealth on the reservation.

An Exploration Of Resilience In Native American Older Adults, Georgie Victoria Ferguson

Graduate Student Theses, Dissertations, & Professional Papers

Native American older adults remain underrepresented in psychological research. The unique cohort of participants in this study (born 1924 - 1957) possesses experience and knowledge that can greatly enhance the knowledge base and contribute to the overall understanding of culturally embedded resilience. Participants contributed to the identification of Spirituality and Humor as positive, culturally embedded coping factors through a set of qualitative interviews, and the present study further investigates those specifically identified coping processes using quantitative measures. This research explores how these constructs (measured by the Spiritual Well-Being and Multidimensional Sense of Humor Scales) might counteract (main effect) or buffer …

Comparative Bioinformatic Methodologies In Paleogenetic Pathogen Identification In The Casas Grandes, Victoria Lynne Giovannangelo

Graduate Student Theses, Dissertations, & Professional Papers

The application of metagenomic tools to further elucidate ancient DNA (aDNA) holds promise in paleopathology, particularly for inferring disease patterns in ancient populations, especially in those that are understudied. This study conducts a comparative analysis of the efficacy of taxonomic pipelines--Kraken 2, HOPS/MALT, and HAYSTAC--in detecting pathogens within highly degraded aDNA samples extracted from 22 Medio Period Paquimé individuals from the Casas Grandes archaeological site in Northwest Mexico. The taxonomic results from the pipelines are compared with contamination detection program mapDamage, although concerns arose about the latter program’s ability to work with prokaryotes. Additionally, the findings are compared against prior …

A Novel Positive Allosteric Modulator Of Glun1/3 Nmda Receptors, Samuel A. Galindo

Graduate Student Theses, Dissertations, & Professional Papers

The GluN3-containing (GluN1/3) N-methyl-D-aspartate (NMDA) receptors are glycine activated ligand-gated ion channels that are members of the family of excitatory ionotropic glutamate receptors. Compared to the glycine/glutamate-activated GluN2- containing NMDA receptors (GluN1/2), which have been extensively studied, the GluN1/3 receptors are poorly understood, but are implicated in neuronal processes related to synaptic maturation and plasticity. GluN1/3 receptors are also implicated in a variety of neurological diseases. In addition to their poor understanding, we lack proper pharmacological tools for the study and modulation of these GluN1/3 receptors. In this study, we evaluate the activity and mechanism of action for AIMS-129 as …

Linking Empirical Data And Numerical Simulation To Characterize Dynamic Fire Behavior Associated With Interacting Firelines, Marta Sergeevna Jerebets

Graduate Student Theses, Dissertations, & Professional Papers

Understanding fuel pattern-fire process relationships is key for predicting fire behavior and effects with follow-on benefits to proactive fire management and model validation. To characterize dynamic fire behavior, this thesis leverages empirical data and numerical simulation through two complementary studies.

In the first study, longwave thermal sensors aboard unmanned aerial systems (UAS) were used to capture fine-scale fire behavior in two experimental grass burns. A novel paired design was used to quantify the effects of fuel arrangement on fire behavior with 3.66 m diameter treatments cut to a height of 0.15 m. The treatments ephemerally reduced fire rate of spread …

Cullet, Celia Alice Easton Koehler

Graduate Student Theses, Dissertations, & Professional Papers

“Cullet” is an industry term for the refuse and smashed-up glass added to new material in the process of making new glass. It is related to the word “cull” from the old french “to collect” or gather. This collection of poems picks up the term as a framework for investigating the piece-meal of daily life, tracing relations between the individual and collective, and also tracing vantage and scale; shifts of where and how the speaker directs their gaze. The poems are invested in assembling an ethos of the domestic that recasts “the domestic” to include more public sites of daily …

The Impact Of Ambient Air Quality On Asthma Outcomes In California, Abigail Obour

Graduate Student Theses, Dissertations, & Professional Papers

This study investigates the relationship between ambient air quality and asthma-related health outcomes in California, focusing on emergency department visits and hospitalizations from 2005 to 2022. Despite California’s strict air quality standards, individuals still face significant pollution challenges contributing to poor respiratory health, particularly among vulnerable populations. Therefore, this study looks at how fine particulate matter (PM2.5) affects asthma outcomes using panel data from 37 counties. A fixed effects regression model is employed to control for unobserved heterogeneities that are constant over time but vary across individual counties, ensuring robust estimates of the impact of pollution on health outcomes. This …

Mitochondrial Dna Diversity In West Mexico, Emma Zoiss

Graduate Student Theses, Dissertations, & Professional Papers

The long-standing movement of people, exchange of goods, and transmission of cultural traits are imprinted not only in the archaeological record but also within the genomes of individuals, making ancient DNA a powerful tool for uncovering past interactions and population dynamics. Despite attempts at systematic research, we are still missing critical information about pre-Columbian Mesoamerican populations in the Aztatlán region. This research will focus on those individuals recovered from archaeological sites located both in the highlands of the Lake Chapala Basin, as well as the coast of the Aztatlán core region. The integration of genetics into our understanding of the …

Graduate Student Theses, Dissertations, & Professional Papers

Learning in P-12 classrooms is filled with joy and social-emotional challenges. As a result, teachers are on the front line of addressing students’ social-emotional needs in the classrooms. Less is known, however, about how teachers integrate social-emotional learning (SEL) into teaching academic subjects and daily classroom activities to support their students. Using an explanatory sequential mixed-methods design, this study explored factors influencing teachers’ integration of SEL in their classrooms and their experiences in facilitating students’ SEL skills. 102 teachers in Montana participated in the initial quantitative phase of the study by completing surveys that examined whether and how teacher factors …

The Power Of The Visual Arts To Explore Who We Are And Where We Come From: A Qualitative Phenomenological Study, Jemina Watstein

Graduate Student Theses, Dissertations, & Professional Papers

Globalization has changed education, how external influences in our world make us who we are, and how we identify ourselves. Changes caused by globalization have had psychological consequences that have made formulating one’s identity more challenging than ever before, especially for a third culture kid (TCK) who lives a multicultural lifestyle and may attend a different school every year.

One developmentally appropriate way of reducing the adverse outcomes for TCKs is through visual art education. Engagement in genuine inquiry and creation through the process of making, perceiving, and reflecting provides students an opportunity to investigate their multicultural, mobile, and fluid …

Fungal Symbionts As Hidden Architects Of Forest Health: From Tree Immunity To Beetle Nutrition, Lorinda Sabin Bullington

Graduate Student Theses, Dissertations, & Professional Papers

Symbioses of fungi with trees and insects play outsized roles in forest ecosystems, influencing tree growth, defense, physiology, and nutrient cycling. While their functional contributions are widely recognized, they remain poorly understood. I integrate findings from three studies examining fungal interactions with conifers and with bark beetles to highlight their significance in tree resistance to disease, nutrient redistribution within the tree, and forest ecology.

First, I demonstrate that foliar fungal endophytes and ectomycorrhizal fungi, together and independently, can enhance resistance in Pinus monticola seedlings against Cronartium ribicola, the pathogen responsible for white pine blister rust. Symbiont inoculation induced host terpene …

Jurisprudence Of Problem-Solving Courts: A Study Of Structure, Success, And Sociological Theory, Lauren M. Boos

Graduate Student Theses, Dissertations, & Professional Papers

In response to the failures of mass incarceration and its disproportionate impact on marginalized communities, Problem-Solving Courts (PSCs) have emerged as alternatives to traditional prosecution. These courts employ therapeutic-informed and rehabilitative practices aimed at addressing the root causes of criminal behavior. While widely regarded as more effective than traditional courts, PSCs have developed largely without a formal theoretical foundation. This is notable given their alignment with Sociological Jurisprudence (SJ) and Therapeutic Jurisprudence (TJ), which view the legal system as a vehicle for promoting individual and community well-being.

Despite being celebrated as therapeutic innovations, PSCs often embody these principles unevenly. Using …

Situation Assessment Of Wildland Fire Preparedness Efforts In Missoula County: A Communities Of Practice Approach, Sylvia K. Coston

Graduate Student Theses, Dissertations, & Professional Papers

Due to the multi-jurisdictional nature and increased risk of wildland fire, collaboratives play an important role in creating long-term solutions for building prepared and resilient wildfire landscapes and communities. Drawing from Communities of Practice (CoP) theory, mutual engagement, shared repertoire, and negotiation of a joint enterprise are critical elements of establishing natural resource multi-stakeholder collaboratives or partnerships. This professional paper uses CoP theory to conduct and analyze a situation assessment of Missoula County Fire Protection Association (MCFPA). With the support of MCFPA, three focus groups (working meetings) and two interviews were conducted to identify the association’s successes, challenges, and needs. …

Visual Semiotics In Parks: Assessing Pictorial Symbol Effectiveness In Outdoor Recreation Settings, Miranda Jane Foster

Graduate Student Theses, Dissertations, & Professional Papers

As interest in outdoor recreation grows, so does the need for effective communication in parks and protected areas. With a larger, more diverse visiting population, managers face new challenges, including intensified recreational use, staffing demands, and barriers to communication presented by cultural and linguistic diversity (Manning et al., 2017; Perry et al., 2021). Effective, indirect communication tools, such as pictorial symbol signage, are essential for addressing these challenges. Pictorial symbol signs are widely used in recreational signage and serve as vital indirect management strategies for communicating to diverse visitors as a universal visual language (Davies et al., 1998). However, research …
