Parent And Child Characteristics Impacting Identification Of Children With Developmental Language Disorder (Dld), Sarah E. Floyd

Graduate Student Theses, Dissertations, & Professional Papers

Purpose: Previous research has shown that children with developmental language disorder (DLD) and dyslexia are under-identified in the general population. Parent or caregiver concern is a primary referral tool for these conditions, but may fail to accurately align with the actual presence of a disorder. The purpose of this study was to examine child and parent characteristics related to a child’s likelihood of receiving a diagnosis of DLD.

Methods: Within a large, 5-year, longitudinal study, kindergartener performance on a battery of speech, language, and literacy measures was examined to identify children with and without DLD and possible risk of dyslexia. …

Mark My Words: The Linguistic Complexity Of The Journal Of Personality And Social Psychology Abstracts And Subsequent Citations, Alivia Lauren Zubrod

Graduate Student Theses, Dissertations, & Professional Papers

Through language, scientific communication can positively impact the progression and advancement of science. Given the value of scientific communication, it is important to explore what factors might be associated with influential scientific communication. Surprisingly, relatively little research has examined the linguistic properties of influential scientific communication. In effort to overcome this gap in the literature, I used integrative complexity, a well-validated linguistic variable, to assess the relation between article abstracts and subsequent number of citations from one of the most highly-cited social psychology journals (Journal of Personality and Social Psychology). In an analysis of over 1.4 million words from 9,884 …

Challenges And Promises Of The Agricultural Sector In The West Today, Jordan J. Unger

Graduate Student Theses, Dissertations, & Professional Papers

The transition from hunter-gatherers to a sedentary, agrarian based society was a pivotal point in history, fundamentally altering humanity’s trajectory. Early human’s domestication of plants and animals paved the way for modern civilization and drastically changed the way we lived and interacted. With agriculture, humans could invest more time into other activities besides procuring food while simultaneously being able to support increasingly large communities of people. Villages, city-states and, ultimately, states were formed – helping give rise to more complex social structures.

Until recently, agriculture has been the main economic backbone of every civilization. In 1970 in the United States, …

Facilitating Aquatic Invasive Species Management Using Satellite Remote Sensing And Machine Learning Frameworks, Sean C. Carter

Graduate Student Theses, Dissertations, & Professional Papers

The urgent decision-making needs of invasive species managers can be better met by the integration of biodiversity big data with large-domain models and environmental data products in the form of new workflows and tools that facilitate data utilization across platforms. Timely risk assessments allow for the spatial prioritization of monitoring that could streamline invasive species management paradigms and invasive species’ ability to prevent irreversible damage, such that decision makers can focus surveillance and intervention efforts where they are likely to be most effective under budgetary and resource constraints. I present a workflow that generates rapid spatial risk assessments on aquatic …

Lead is a cumulative toxin that can affect multiple systems in the human body. Exposure occurs through various sources, such as outdated and deteriorating infrastructure, paint, soil and drinking water. This project, a three-part audio series on lead exposure in Montana highlights various paths of exposure and how young children under age six years of age are particularly vulnerable. Part one is a story about a new state requirement to test all k-12 schools for lead in water fixtures. Part two: A house remodel exposes a family’s children to lead. Getting a diagnosis wasn’t easy. Part three: A look at …

Ghosts, Hauntings, Kinship, And Contamination: Key Tropes For Narrating Extinction In Jeff Vandermeer's Hummingbird Salamander And James Bradley's Ghost Species, Christopher Hardesty Nicholson

Graduate Student Theses, Dissertations, & Professional Papers

This thesis examines the narrative portrayals of issues pertaining to anthropogenic extinction in two contemporary speculative fiction novels: Jeff VanderMeer’s Hummingbird Salamander (2021) and James Bradley’s Ghost Species (2020). This focus leads to consideration of narrative genre, tropes, and affective resonance. The first half of this thesis centers the genres of tragedy and elegy, their tropes of ghosts and hauntings, and the affective processes of grief and horror. Within these narrative frameworks extinction is experienced as a claustrophobic site of horror in Hummingbird Salamander, and as a time-warping inspiration of grief in Ghost Species. However, in each novel …

Mansfield, Marines, And Mothers: The Politics Of Resistance To The American Intervention In North China From 1945-1946, James Robert Compton

Graduate Student Theses, Dissertations, & Professional Papers

At the conclusion of World War II, American citizens, including millions of deployed servicemen, reasserted the democratic freedoms they sacrificed to win the war. The American intervention in North China during the Chinese Civil War presented a ripe opportunity for civic restoration in late 1945. Controversial and seemingly at odds with the stated goals of the Second World War—namely the “Four Freedoms” and the Atlantic Charter—the US military presence in North China faced formidable domestic political obstacles. This thesis explores the nexus of domestic politics and foreign policy in the post-World War II era. Focusing on 1945-1946, this project steps …

A Qualitative Examination Of Teacher's Perspectives Of Social-Emotional Learning And Spirituality In The Public School Setting, Amy E. Violante

Graduate Student Theses, Dissertations, & Professional Papers

Spirituality is not often discussed in the field of school psychology or the public school setting. However, it is understood to be a factor supporting resilience and well-being among children. Aspects of spirituality align with the core components of social-emotional learning (SEL), which relate to awareness of self and others, relationship skills, and responsible decision-making. The aims of the current study were to explore public school teachers’ perspectives of spirituality and SEL in the classroom, of the relationship between these topics, and of supporting spiritual and SEL development in order to promote student well-being. Semi-structured interviews were conducted with twelve …

1-D Crustal Seismic Velocity Models For West-Central And Western Montana, Courtenay Duzet

Graduate Student Theses, Dissertations, & Professional Papers

In seismically active areas with infrequent, large-magnitude earthquakes, high-quality seismic data are critical for determining high-resolution, accurate seismic velocity models. Here, we present a new local-scale seismic velocity model for the crust in west-central Montana as well as a new regional-scale seismic velocity model for the crust and upper mantle across broader western Montana. The new models are constrained by phase arrivals from several passive seismic networks, including the University of Montana Seismic Network (UMSN), the Montana Regional Seismic Network (MRSN), the Advanced National Seismic System (ANSS), temporary deployments by the United States Geological Survey (USGS), and the USArray Transportable …

Bridging The Gap: Where Indigenous Knowledge And Western Science Come Together To Shape Environmental Stewardship, Bowman Leigh

Graduate Student Theses, Dissertations, & Professional Papers

In the era of climate change, humans are grappling with how to ensure that natural resources exist into the future. For millennia, Indigenous people have actively managed the environment, drawing upon deep connections to the land passed down through generations. The Western worldview, on the other hand, sees humans as separate from nature — an attitude that has led to many of the environmental crises we see today.

This portfolio examines places and programs where Western science and Indigenous knowledge (IK) or traditional ecological knowledge (TEK) come together to shape environmental stewardship. Western science and IK/TEK are inherently different ways …

Understanding Media Richness And Social Presence: Exploring The Impacts Of Media Channels On Individuals’ Levels Of Loneliness, Well-Being, And Belonging, Ashley M. Arsenault

Graduate Student Theses, Dissertations, & Professional Papers

Loneliness is a universal part of being human and is detrimental to well-being. The need-to-belong hypothesis claims that individuals frequently having positive interactions with people close to them mitigates their loneliness. Media richness theory adds that rich media channels allow individuals to perceive higher levels of social presence and maintain those vital, close relationships. Understanding how a given media channel impacts online interactions and, in turn, the interactants is vital. This study used a pretest-posttest equivalent groups experimental design to examine if individuals who interacted with a close relationship partner over a rich media channel would have a decrease in …

Subfamily Clustering Using Label Uncertainty (For Transposable Element Families), Audrey M. Shingleton

Graduate Student Theses, Dissertations, & Professional Papers

Biological sequence annotation is typically performed by aligning a sequence to a database of known sequence elements. For transposable elements, these known sequences represent subfamily consensus sequences. When many of the subfamily models in the database are highly similar to each other, a sequence belonging to one subfamily can easily be mistaken as belonging to another, causing non-reproducible subfamily annotation. Because annotation with subfamilies is expected to give some amount of insight into a sequence’s evolutionary history, it is important that such annotation be reproducible. Here, we present our software tool, SCULU, which builds upon our previously-described methods for computing …

Identifying Skeletal Trauma Markers Associated With Intimate Partner Violence (Ipv), Haley K. Omeasoo

Graduate Student Theses, Dissertations, & Professional Papers

Objectives: This is a validation study of Biddle (2019), where much of the same materials are used, with the addition of new data from other databases to include more Native American and minority samples. A comparison database will also be analyzed against this data, with known cases of live individuals assaulted and assessed by health officials, some in IPV situations. All data is analyzed to discover which fracture locations are most common in IPV situations and which ethnic, sex, and age groups are most affected. Most fractures analyzed are those of the maxillofacial area, concentrating on the Zygomaticomaxillary Complex (ZMC) …

Combined Effects Of Temperature And Heavy Metals On The Performance Of The Giant Salmonfly., James Frakes, Amanda Andreas, Benjamin P. Colman, Aurthur Woods

Graduate Student Theses, Dissertations, & Professional Papers

In many freshwater ecosystems, communities of aquatic insects are facing the combined stresses of warmer waters due to climate change and increased exposure to heavy metal toxicants. Although each stressor may threaten aquatic insects independently, they also likely interact in important ways to affect insect physiology and performance. Here we investigate this potential interaction using two populations of aquatic nymphs of the giant salmonfly, Pteronarcys californica, collected from adjacent rivers in Montana: naïve individuals from Rock Creek, a relatively pristine stream, and individuals from the Upper Clark Fork River, which has a history of heavy metal pollution and higher …

Looking To The Future Of Wildlife Conservation: Durable Wildlife Policy For The 21st Century, Charlie R. Booher

Graduate Student Theses, Dissertations, & Professional Papers

Wildlife conservation in the United States was built by the dollars of consumptive users. Monies from the sale of hunting licenses, as well as excise taxes on firearms, ammunition, and archery tackle through the Pittman-Robertson Federal Aid in Wildlife Restoration Act (PR), currently fuel a complex system of wildlife conservation via multiple levels of government. However, the number of hunters in this country is rapidly declining, the sale of firearms and ammunition is increasingly unrelated to hunting, and contemporary consumers tend to express different values than traditional hunters. These changes pose significant challenges of relevancy and funding to state and …

Keeping What You Sow: Intellectual Property Rights For Plant Breeders And Seed Growers, Paulina B. Jenney

Graduate Student Theses, Dissertations, & Professional Papers

Over the last 150 years, the food system in the present-day United States has undergone a transformational restructuring, from a diversified, decentralized, network of farmers and seed growers, to one in which the majority of crop production is controlled by a few industrial corporations. The consolidation of power has been under-girded by the application of intellectual property rights (IPR)—especially utility patents—to plant varieties and genetic traits, which are leveraged to exclude small-scale seed growers from accessing quality germplasm. Patents and restrictive licensing agreements recapitulate colonial structures by appropriating common and traditionally community-held resources for profit, and by creating reliance on …

Evaluating The Use Of Camera Traps To Monitor Populations Of Ungulate Prey In The Russian Far East, Scott Johnston Waller

Graduate Student Theses, Dissertations, & Professional Papers

Efforts to recover endangered carnivore populations are often limited by insufficient populations of prey. When recovering prey populations, estimates of population density are invaluable metrics to monitor recovery efforts. In Russia, wildlife managers use the Formozov-Malyushev-Pereleshin (FMP) snow tracking method to estimate densities of ungulate prey of the Amur tiger (Panthera tigris). Yet, increasing variability in snow conditions and other challenges have limited its reliability. Camera traps offer a promising alternative approach since managers already use cameras to monitor tigers. However, the assumptions and study design necessary to implement capture-recapture models for tigers are different from those needed …

Saving A Species: A Look Into Novel Techniques Being Used To Conserve Wildlife, Sierra R. Cistone

Graduate Student Theses, Dissertations, & Professional Papers

Wildlife is held in public trust, and the public plays an important role in management and conservation as voters, advocates and beneficiaries of the many services and enjoyment that wildlife provides. But understanding wildlife issues, conservation and management decisions can be challenging given the often complex science around wildlife ecology and diverse public perspectives. That is why careful and accurate reporting around wildlife and environmental topics is imperative and a requirement of a well-informed electorate. This master’s portfolio is a collection of extensively reported stories around wildlife issues that are designed to be accessible to general readers to fulfill that …

Evaluating The Management And Consequences Of Hybridization Between Nonnative Rainbow Trout And Native Westslope Cutthroat Trout, Anthony James Dangora

Graduate Student Theses, Dissertations, & Professional Papers

The introduction of nonnative fish is a major driver in the decline of native fish species. Nonnative rainbow trout (Oncorhynchus mykiss; RBT) introduced into the native range of westslope cutthroat trout (O. clarkii lewisi; WCT) have led to the introgressive hybridization between these two species. This widespread hybridization is a primary threat to the long-term persistence of WCT as it can cause population-level genomic extinction. Since there are no set management solutions for hybridization, there is a need to evaluate the different conservation approaches to ensure the persistence of WCT populations. Additionally, beyond propagule pressure, the array of drivers that …

Is Growing Food Wasting Water? Stories From A Surge Of Groundwater Regulations In California, Abigail Jean Lauten-Scrivner

Graduate Student Theses, Dissertations, & Professional Papers

This long-form feature story examines how the nascence of California’s new era of groundwater regulation is playing out for the farmers, families and agencies who must adapt to a sweeping new law against the backdrop of climate change.

California became the last state in the west to adopt a statewide management plan for the invaluable natural resource when it first embarked on a path toward groundwater sustainability in 2020. Known as the Sustainable Groundwater Management Act (SGMA), the 20-year plan requires California’s most depleted groundwater basins to become sustainable by 2040.

When SGMA matured in 2020, California’s next drought began …

A Thinking Person's Guide To Immigration And Environmental Racism At The Us - Mexico Border, Emma H. Kiefer

Graduate Student Theses, Dissertations, & Professional Papers

In recent years, more attention has been paid to the immigration crisis at the US-Mexico border thanks in part to the strict immigration restrictions from the Trump administration, such as the family separation policy. Immigration remains a widely misunderstood issue and arguments against increased immigration are often laced with racist stereotypes and perceptions that find their roots in centuries of US policy, court cases, and administrative rules. Similarly, the concept of environmental racism can be difficult for the American public to understand when modern-day racism alone has become more insidious. Intersectionality, a concept coined by sociologist Kimberlé Crenshaw, asks us …

A Machine Learning Algorithm Improves Surface Freeze-Thaw Classification, Fredrick Bunt

Graduate Student Theses, Dissertations, & Professional Papers

The frozen or thawed state of the land surface is an important factor affecting a wide range of natural processes such as surface water movement, the carbon cycle, and ecosystem development. It is also important for human endeavors such as permafrost engineering and agricultural planning. This makes having an accurate record important. The Freeze-Thaw (FT) Earth System Data Record (FT-ESDR) is a global, daily product that strives to be a reliable record of the FT ground state. In its current form, the FT-ESDR uses annual regression analysis of reanalysis surface air temperatures (SAT) and brightness temperatures (Tb) at each grid …

Conserving And Sharing Freshwater In The West, Kelsea Harris-Capuano

Graduate Student Theses, Dissertations, & Professional Papers

There are infinite stories to be told about water in the West. As an essential and finite resource, countries, states, tribal nations and neighbors must figure out how to manage this shared resource, whether for ecosystem sustainability, agricultural, household, or recreational use.

Sensitivity Of Lidar Derived Fuel Cells To Fire Modeling At Laboratory Scale, Anthony Albert Marcozzi

Graduate Student Theses, Dissertations, & Professional Papers

Computational models of wildfires are an important tool for fire managers and scientists. However, fuel inputs to wildfire models can be difficult to represent with sufficient detail to be both computationally efficient and representative of observations. Recent advances in fuel mapping with airborne and terrestrial laser scanning (LIDAR) techniques present new opportunities to capture variation in fuels within a tree canopy and on a landscape. In this paper, we develop a technique for building 3D representations of vegetation from point clouds created by Terrestrial Laser Scans (TLS). Our voxel based approach can be extended to represent heterogeneous crown fuels as …

For The Love Of Language: Microrituel In The Socialization Of Language Teachers, Rebekah Morgan Skoog

Graduate Student Theses, Dissertations, & Professional Papers

Language and social interaction have been determined to be intricately linked. Over the past century, studies surrounding how to learn languages have shifted the conversation on how to teach them. With the introduction of Hymes’ (1971) Communicative Competence into pedagogical literature, learning language within social context replaced the formally grammar based, traditional methods. During the early 1960’s the American Council for the Teaching of Foreign Language led the charge on providing standards and learning objectives to shift language learning towards a more integrated and communicative approach. However, based on the research of Celce-Murcia (2007), Aguilar (2007), and Ishihara & Cohen …

The Syndemic Landscape: A New Paradigm For Montana Suicide Prevention Grounded In Agricultural Renewal, Emory Chandler Padgett

Graduate Student Theses, Dissertations, & Professional Papers

Montana has had one of the highest suicide rates in the nation for half a century, and since 2000, it has risen almost 50%. Despite suicide’s alarming persistence in the state, there has been minimal academic study of suicide or mental health specifically in Montana, so this thesis attempts to answer a few questions: Why does Montana have such a high suicide rate? Is there something culturally, historically, or socially unique about Montana that contributes to suicide? Are current prevention efforts helpful, harmful, or lacking? Could a consideration of culture and land benefit an understanding of suicide in Montana? What …

Spatial Behavior, Foraging, And Population Dynamics Of A Subarctic Ungulate, Elizabeth (Libby) Parr Williamson Ehlers

Graduate Student Theses, Dissertations, & Professional Papers

The concept of density-dependence is foundational to our understanding of the ecology and management of large herbivores. As the abundance of large herbivores increases, competition for high-quality resources increases and animals select for lower-quality foods potentially resulting in reduced vital rates that cause declines in population growth. What remains unclear is how foraging at finer scales, like the ‘bite’, translates to demography. This is difficult because it’s challenging to scale bite-level foraging to population-levels. I test the fine-scale foraging mechanisms of density dependence in a large subarctic herbivore, Barrenground caribou (Rangifer tarandus granti). The nutritional landscape for arctic herbivores is …
