School Change For Sustainability, Ryder Delaloye

Graduate Student Theses, Dissertations, & Professional Papers

The welfare of current and future generations is diminished due to unprecedented levels of ecological degradation that is a result of accelerating levels of per capita consumption. Sustainability education is being widely embraced as an applied strategy for addressing both unchecked consumption and environmental degradation (Brown, 2003). Yet, little is known about how schools adopt and implement sustainability education. The means by which to engage and foster sustainability education is not well researched. This qualitative research study seeks to address the following research question: How did students and faculty at each school site go about the process of creating and …

Contributions Of Gene Copy Number Variation To Genome Evolution And Local Adaptation Of The Cyanobacterium Acaryochloris, Amy L. Gallagher

Graduate Student Theses, Dissertations, & Professional Papers

Acaryochloris is a recently discovered genus of cyanobacteria, unique in its use of an uncommon chlorophyll as its major photosynthetic pigment, and in its peculiar genome dynamics. Members of this genus exhibit increased genic copy number variation (CNV), which is thought to be primarily derived from gene duplications and horizontal gene transfer (HGT). Acaryochloris provides an ideal system to explore mechanisms behind maintenance of gene duplicates and the influence of CNV in local adaptation. Here, I propose a mechanism for retention of gene duplicates of the bacterial recombinase, RecA, in Acaryochloris genomes and provide preliminary evidence that these paralogs are …

Does Timing Of Herbicide Use Influence Rates Of Germination Or Seedling Biomass Of Native Plants Used For Restoration?, Christine Mcmanamen

Graduate Student Theses, Dissertations, & Professional Papers

Invasive plants can negatively impact native grasslands by changing their species composition, productivity, and function. Managers commonly use herbicides as a control method; however, this practice can lead to secondary invasion by other non-native invasive plants, unless measures are taken to promote natives. Because of this, managers often seed native plants after spraying herbicides. There is evidence, however, that chemical control of invasive plants may reduce the effectiveness of subsequent seed-addition treatments, but there is currently little quantitative information on optimal timing between spraying and seeding or on variation in herbicide sensitivity among native plants commonly used in seed mixes. …

Police Decision-Making And The Initial Detention Of Juveniles, Tessa G. Decunzo

Graduate Student Theses, Dissertations, & Professional Papers

Police decisions can have a direct impact on juvenile outcomes. These decisions are especially impactful in Montana as Montana law enforcement officers are provided statutory discretion pertaining to the decision to arrest and initially detain a youth. The goal of this study is to understand police officer decision-making as it pertains to the initial detention of juveniles and to inform future theory and policy. The research was guided by a focused hypothesis: The factors identified by law enforcement will be significant predictors of the factors associated with the likelihood of initial detention. In order to examine this issue, the current …

Further Investigating The Underlying Attentional Processes Of Brief Mindfulness-Based Interventions, Erin Rachelle Yosai

Graduate Student Theses, Dissertations, & Professional Papers

Mindfulness-based interventions (MBIs) incorporate components of mindfulness into treatment strategies for both general and specialized populations. Within the school setting, research shows that MBIs contribute to student improvement in cognitive functioning, and the brief MBIs (e.g., around 8 minutes) can improve scores on standardized tests (Mrazek et al., 2013; Zenner et al., 2014). However, it is unclear what cognitive processes may be improved through MBI implementation. The current project investigated components of attentional control through working memory capacity, inhibition, mind-wandering, mood, and task-switching as cognitive processes that may be improved by MBIs. University undergraduates (N=119) aged 18-25 (M=20.11, SD=1.94) participated …

Neon Is Trying To Tell You Something, Grace Arenas

Graduate Student Theses, Dissertations, & Professional Papers

The following is the manuscript of my poetry collection, “Neon is Trying to Tell You Something.” This manuscript represents my development of poetic voice and style over the course of the past two years. In these poems, images accrue and take on new meaning, while still retaining echoes of their original connotations. This is how the speaker’s mind makes sense of things: evolutionarily. As a collection, these poems do not attempt to world-build or use their foreign landscapes as the driving force of symbol, but rather they use these landscapes as the essential terminology for their logic puzzles, their syllogistic …

Lgbtq-Inclusive Sexuality Education In Montana Public High Schools: An Assessment Of The Needs Of Health Enhancement Teachers, Andrew G. Johnson

Graduate Student Theses, Dissertations, & Professional Papers

BACKGROUND

LGBTQ youth face many unique health challenges. Rates of depression and suicide are exponentially higher for LGBTQ youth than for their heterosexual, cisgender peers. Rates of HIV and STI infection are rising among this demographic. Comprehensive sexuality education has demonstrated the potential to address some of these health challenges. Specifically, it has been shown to delay the onset of sexual intercourse, and to reduce pregnancy and transmission rates of HIV and STIs among youth. Several studies have looked at LGBTQ-inclusive sexuality education from the perspective of LGBTQ students, but few have looked at this issue from the perspective of …

New Methods To Estimate Abundance From Unmarked Populations Using Remote Camera Trap Data, Anna K. Moeller

Graduate Student Theses, Dissertations, & Professional Papers

Abundance estimates are central to the field of ecology and are an important tool for wildlife managers. While many tools are available for estimating abundance from individually identifiable animals, it is much more difficult to estimate abundance of unmarked animals. Most species have no natural markings and capturing them to apply artificial marks is invasive. One step toward noninvasive abundance estimation is the use of passive “traps” such as remote cameras or acoustic recording devices. The continuous-time data from these traps can be used to estimate abundance, although most available methods still require individually identifiable animals. There is a great …

Concussion Knowledge Of Missoula Youth Hockey Participants And Their Parents, Samantha Riordan

Graduate Student Theses, Dissertations, & Professional Papers

Abstract:

Background: The Dylan Steigers Protection of Youth Athletes Act (DSPYAA) was passed by Montana legislature in 2013 which calls for mandatory concussion education of coaches, parents, and athletes. This law only applies to school sponsored sports, excluding those involved in youth sports organizations (YSO), such as youth hockey.

Hypothesis: Participating youth athletes and parents will not be able to identify signs and symptoms of a concussion and will not be able to identify future consequences of a poorly managed concussion.

Study Design: Cross sectional survey. Level of Evidence: Level 4

Methods: A descriptive questionnaire, Concussion Knowledge in Youth Sports …

Stream Restoration Effects On Hydraulic Exchange, Storage And Alluvial Aquifer Discharge, Christine M. Brissette

Graduate Student Theses, Dissertations, & Professional Papers

Stream restoration is increasingly being considered as a climate change mitigation tool, altering the storage and exchange capacities of streams and their adjacent alluvial aquifers. While previous research has shown that added geomorphic complexity and increased width-to-depth ratios can enhance hydraulic exchange and alluvial aquifer storage, few studies have used field data to link these changes in form to baseflow generation. In this paper, we quantify the effect of stream restoration on nested scales of hydraulic exchange and temporal patterns of alluvial aquifer recharge and discharge. Our work compares a restored and degraded reach on Ninemile Creek, Montana following extensive …

Predicting Habitat Distribution For Five Rare Plant Species Within The Blackfoot Swan Landscape Restoration Project, Annalisa Suzan Ingegno

Graduate Student Theses, Dissertations, & Professional Papers

This study predicted rare-plant habitat at the landscape scale. Using the Maximum Entropy (MaxEnt) algorithm, relationships to and between each environmental variable were quantified for five species in the Blackfoot Swan Landscape Restoration Project (BSLRP) study area in western Montana. This project is part of a greater vegetation assessment for BSLRP that utilizes remotely sensed products for planning and management purposes. The five rare plant species studied in this analysis were common camas (Camassia quamash), clustered lady’sslipper (Cypripedium fasciculatum), western pearlflower (Heterocodon rariflorum), Howell’s gumweed (Grindelia howellii), and crested shieldfern (Dryopteris cristata). Rare plant models typically do not address dispersal …

Visions Of Sovereignty: Tribal Sovereignty Through The Lenses Of Postcolonialism, Indigenous Film, And Visual Anthropology, Martin I. Lopez

Graduate Student Theses, Dissertations, & Professional Papers

Tribal sovereignty has been a topic of discussion since the beginning of colonization in America. Anthropological thought, especially postcolonialism theory, addresses how colonialism can be analyzed to gain a better understanding of Indigenous perspectives on sovereignty. Visual sovereignty, an example of Indigenous Film, is an interdisciplinary approach that can contextualize in specific histories and social interactions all while serving individual tribes, depending on which tribe the filmmaker represents. A film, for instance, can be edited in a way to convey Indigenous ideas of time and space and staged presentations of oral histories that are nearly impossible to display through written …

Chairperson: Dr. Anna Marie Prentiss

The Bridge River site is located near the confluence of the Bridge and Fraser Rivers in the Mid-Fraser canyon near Lillooet, British Columbia. This region has long been popular for archaeologists seeking to understand the emergence of wealth-based inequality in complex hunter-gatherers. Housepit 54 is one of over 80 pithouses or s7ístken that was continuously occupied throughout most of the village history. It …

The Balancing Act: Ecological Interventions And Decision Tradeoffs To Preserve Wilderness Character, Lucy A. Lieberman

Graduate Student Theses, Dissertations, & Professional Papers

Global climate change, land use intensification and increasing development are impacting federal wildernesses in new and unprecedented ways. Ecological restoration is one tool that that wilderness managers are using to combat degradation, though the decision to intervene in wilderness is complicated by the Wilderness Act’s legal mandate to preserve wilderness character and demonstrate managerial restraint. The purpose of this study is to document a baseline of ecological interventions that have occurred in the NWPS over the last five years, and to understand how wilderness managers make decisions related to ecological interventions. I sent a quantitative survey to over five hundred …

Are Maximum Ground Forces And Leg Compression In Phase? A Test Of The Classical Spring Mass Model Of Running Gaits, Seth Donahue

Graduate Student Theses, Dissertations, & Professional Papers

The mechanical understanding of human running has classically been described as a spring-mass system, with subsequent models predicting the movements of the body’s center of mass and the forces applied by the leg against the ground. A central requirement of any spring system is the phasic relationship between the length of the elastic elements and the forces applied to these structures. Specifically, elastic elements compress under load and extend as the load is released. We tested whether this model applies to individuals with specialization for extreme performance in human gait. Recent work from elite level sprint runners suggest that their …

Fertility And Reproduction's Niche: Human Sexual Diversity, Samuel W. Austin

Graduate Student Theses, Dissertations, & Professional Papers

Abstract: Biologically exploring the origins and forms of human sexuality is of paramount importance. Scientific research has indicated that homosexuality was linked to reproduction, fertility, and adaptive child caring strategies, traits that seem to display cross-cultural similarities. This suggests that sexual diversity may be one of human’s earliest adaptations. While most of the previous research has been on individuals of European descent, little research on Native American populations has been completed to test whether these patterns continue in their population.

The research presented here tests the Sexually Antagonistic Hypothesis for Male Homosexuality, Fraternal Birth Order Effect, and childhood atypical gender …

The Influence Of Tree Height On Lidar’S Ability To Accurately Characterize Forest Structure And Spatial Pattern Across Reference Landscapes, Haley L. Wiggins

Graduate Student Theses, Dissertations, & Professional Papers

Successful restoration of degraded forest landscapes requires reference models that adequately capture structural heterogeneity at multiple spatial scales. Field-based methods for assessing variation in forest structure are costly and inherently suffer from limited replication and spatial coverage. LiDAR is a more cost-effective approach for generating landscape-scale data, but it has a limited ability to detect understory trees. Increased understanding of appropriate height cut-offs for trees to be reliably included in LiDAR-based analysis could improve applications of LiDAR to assessments of landscape-scale forest structure. Toward that end, I investigated the effect of varying tree-height criterion (minimum height cutoffs of 6, 9, …

The Relationship Of Reading Self-Efficacy And Reading Achievement In Second Grade Students, Jennifer L. Hager

Graduate Student Theses, Dissertations, & Professional Papers

Academic self-efficacy has been positively related to academic achievement in previous studies with middle school, high school, and undergraduate students. This small-scale study investigated the relationship between student reading self-efficacy and student reading achievement with second grade students in central Montana. Participating students completed a Reading Self-Efficacy Questionnaire and benchmark assessments for reading. The 2011 Dibels Next Reading End of Year Benchmark test was used to measure fluency and the Northwest Evaluation Association Measures of Academic Progress (MAP) Reading for Primary grades test was used to measure the related reading skills of language and writing, foundational skills, literature and information …

Sharing Nature: Rival Visions Of Environmental Discourse, Charles B. Hayes

Graduate Student Theses, Dissertations, & Professional Papers

In this paper I compare and evaluate the work of Steven Vogel, Akeel Bilgrami, and Jedediah Purdy regarding the place of normative conceptions of nature in political discourse. I argue that it is not in principle undemocratic, nor is it theoretically illegitimate, nor domineering to hold and express ideas involving normative conceptions of nature. On the contrary, it is often exemplary political discourse, well suited for deeply questioning our impact on the world and for inspiring collective change.

Ecological Momentary Assessment Of Daily Microaggressions And Stigma-Based Substance Use Among Lesbian, Gay, And Bisexual Individuals, Nicholas Alexander Livingston

Graduate Student Theses, Dissertations, & Professional Papers

Background: People who identify as LGBTQ experience elevated rates of minority stress, which has been linked to higher rates of substance use. Unfortunately, most extant research on this disparity is predicated on cross-sectional or longitudinal research methods that are insensitive to the effects of daily microaggression experiences, or their possible relation to daily substance use risk. The aim of this study was to address this knowledge gap using ecological momentary assessment (EMA). Method: LGBTQ individuals (N = 50) were recruited from the University of Montana, attended a 90-minute orientation to complete baseline measures, and received instruction regarding the proper use …

Performing Whale-Watching In Juneau, Alaska, Chelsea Karthauser

Graduate Student Theses, Dissertations, & Professional Papers

Nature-based tourism activities provide special contexts for human-wildlife interaction. In Juneau, Alaska, summertime tourists seek encounters with humpback whales, hundreds of which feed seasonally in Southeast Alaska’s coastal waterways. Tourists support a thriving whale-watching industry in the region. Voices in nature-based tourism studies, departing from prior rigid conceptualizations of tourism, have identified the need to investigate activities using innovative frameworks to address the tourism experience as an ongoing and fluidly constructed phenomenon. The purpose of this study is to construct a new understanding of nature-based tourism using a performance metaphor. The flexibility provided in a metaphorical approach allows for a …

Poison In Pink, Sydney V. Cook

Graduate Student Theses, Dissertations, & Professional Papers

Humans slather, spray, mist, and cleanse their bodies with personal care products like lotion, hairspray, cologne, and shampoo every day. Our cupboards are stocked full of them, but few of us understand what is in those jars and bottles. We trust that if it’s on the shelf at the store, it’s safe. However, this is not always the case, and many personal care products contain chemicals that are harmful to human and environmental health.

My multi-disciplinary Environmental Studies thesis project combines evidenced-based research, interviews, nonfiction narrative, and science communication to create part of a book manuscript intended to educate general …

Understanding The Client’S Experience Of Counseling In Bhutan, Michaela Maureen Sacra

Graduate Student Theses, Dissertations, & Professional Papers

Bhutan is a small Himalayan country experiencing vast changes as its traditional, Buddhist, collectivist culture meets Westernized culture in the process of globalization. The significant differences in culture and the idealization of the West has led to an increase in mental health issues in Bhutan, especially among the youth population. The government has recognized this and supports the growth of mental health professions. Currently, there are few mental health workers in Bhutan, but they have recently initiated a Bachelors-level counselor training program and have provided brief training to teacher counselors in schools to better address the rising problems. However, there …

Exploring The Relationship Between Childhood Sexual Knowledge Acquisition And Adult Sexual Self-Esteem, Guy Ray Backlund

Graduate Student Theses, Dissertations, & Professional Papers

This dissertation investigated the relationship between sexual knowledge acquisition components (parents, sex education, religion, peers, siblings, media and pornography) in both learning and experience, age of first learning and first sexual experience, and quality of learning and first sexual experience in correlation to the construct of sexual self-esteem. Participants (N = 195) were college undergraduate students from the University of Montana and Gonzaga University between the ages of 18 and 25. A standard multiple regression analysis was performed, and between groups ANOVA post hoc analyses investigated comparisons of sexual knowledge acquisition components by Sexual Self-Esteem Inventory scores (SSEI) (Zeanah & …

Set The Net: The Heritage Significance Of Fish Camp And Wild Salmon In Bristol Bay, Alaska, Sarah Jane Braund

Graduate Student Theses, Dissertations, & Professional Papers

In over 10 years of environmental and socioeconomic studies surrounding the controversial Pebble Limited Partnership mine project design and permitting, commercial salmon fishers’ voices in Bristol Bay, Alaska remain unheard. To meaningfully participate in cultural resource management decision-making that affects them, communities need to speak, yet fisher communities rarely have an established voice. This dissertation uses critical collaborative ethnography and Indigenist research paradigms to describe how the recognition of living heritage communities can be facilitated through the identification of ethnographic landscapes. Such landscapes reflect the meaningful relationship of culture and place, concepts that are currently under-represented in Alaska. Not only …

What The Gringos Brought: A Critical Examination Of A Privately Protected Area In Chilean Patagonia, Elena Louder

Graduate Student Theses, Dissertations, & Professional Papers

Neoliberal ideology increasingly underscores many mainstream efforts to conserve biodiversity. This research explores this convergence through an in-depth case study of a privately owned park located in Chilean Patagonia. In two complementary chapters, I assess the social and cultural impacts of the project, and examine the role of discourse in the process of communicating and constructing the park. In the first chapter I draw from interview data collected from September through December of 2016 and explore the perspectives of local people with a variety of relationships to the project. In the second I employ a critical discourse analysis of park …

Day Hikers And Bear Safety: An Elaboration Perspective On Communication In Yellowstone National Park, Zachary David Miller

Graduate Student Theses, Dissertations, & Professional Papers

As the National Park Service (NPS) celebrates its 100th year, Yellowstone National Park – the world’s first national park - is dealing with a variety of difficult and complex challenges. Human-wildlife conflict has become a flashpoint for these challenges, as increased visitation results in fewer managers dealing with more people in the park. A recent spate of deaths of day hikers in the park due to grizzly bears set further focus on this point. Yellowstone officials realized that effective communication strategies are more important than ever before.

This research was part of a broader project designed to examine the effectiveness …

Evolution Of The Kinetics And Dynamics Of Heme-Crevice Loop Regulating Chemistry In Human Cytochrome C, Shiloh M. Nold

Graduate Student Theses, Dissertations, & Professional Papers

Cytochrome c, cytc, is a metalloprotein that plays primary roles in electron transport and intrinsic apoptotic pathways. Much of the chemistry that cytc is involved with is regulated by a highly conserved region known as the heme crevice loop, consisting of residues 70-85. Only three of these residues (those at positions 81, 83 and 85) are not universally conserved within the evolutionary timeline. Here I look to elucidate possible evolutionary roles for several of the key residues known to be important in regulating heme chemistry of cytc.

I first address the role that lysine …
