Adapting Near-Ultraviolet Colorimetry For Long-Term In Situ Monitoring Of Hexavalent Chromium In Groundwater Aquifers, Janine Carter

Graduate Student Theses, Dissertations, & Professional Papers

This paper briefly describes sources of hexavalent chromium [Cr(VI)] and the risk it poses to human health and the environment; current methods used to regulate, monitor, and measure Cr(VI); the basic design of a submersible, direct-reading sensor in development for long-term monitoring of Cr(VI) concentration in natural waters; and the means developed to correct sensor readings for two common analytical interferences, turbidity and pH, that could lead to an incorrect measurement of Cr(VI). The principal purposes of this study are to analyze the current methods used to compensate for sample turbidity, to develop methods to compensate for sample pH, and …

Src Family Kinases Mediate Individual Cell Responses To Receptor Tyrosine Kinase Signaling In Neuroblastoma Cells, Juan Enrique Palacios Moreno

Graduate Student Theses, Dissertations, & Professional Papers

Receptor Tyrosine Kinases (RTKs) are involved in proliferation, differentiation, cellular metabolism, and homeostasis. More than half of the RTKs in the human genome are expressed in neuroblastoma cell lines. RKTs activate downstream signaling pathways including the canonical pathways of ERK, AKT, PLCγ, and SRC Family Kinases (SFKs). Phosphoproteomic data showed high expression and phosphorylation levels of SFK scaffold PAG1, and SFKs FYN and LYN in neuroblastoma cell lines and endosomes. We hypothesized that FYN and LYN distinguish between proliferation- and differentiation-inducing signals from different RTKs in neuroblastoma cells.

To test this hypothesis, we measured changes in FYN and LYN’s intracellular …

Characterization Of The Assembly Of Human Cytomegalovirus Gh/Gl/Go And Gh/Gl/Ul128-131 Complexes And Studies On Their Functions During Virus Entry And Tropism, Momei Zhou

Graduate Student Theses, Dissertations, & Professional Papers

Human cytomegalovirus (HCMV) is a human pathogen that can cause severe diseases in immunocompromised individuals, and also is a leading cause for congenital infection, making it a major public health concern. Currently, there is no effective vaccine available and antiviral treatment is often associated with problems, like drug toxicity, and drug resistance. Intervention in the virus entry process during the replication cycle could serve as a useful therapeutic strategy. The overall aims of the research in this dissertation are to characterize the roles of HCMV two gH/gL glycoprotein complexes during virus entry and tropism, and to study the molecular basis …

Hazardready – A Geographically Based Natural Hazard Education And Preparedness Web Application, Carson C. Macpherson-Krutsky Ms.

Graduate Student Theses, Dissertations, & Professional Papers

Earthquakes, floods, wildfires, and other natural disasters are inevitable and costly both in terms of lives lost and money spent on recovery. Scientific research on natural hazards is widely shared within the scientific community, but is less often made more widely accessible, as methods or pathways for providing scientific natural hazard information and data in non-technical language are limited. Priorities for imparting hazard information include: 1) scientific accuracy, 2) spatial granularity, 3) integration of information about all relevant hazards, 4) nontechnical content, 5) appropriate preparedness activities, and 6) engagement with existing disaster response and mitigation capabilities. In response to these …

Mechanisms And Consiqences Of Lysosomal Membrane Permeabilization Following Exposure To Bioactive Particles, Forrest Connell Jessop

Graduate Student Theses, Dissertations, & Professional Papers

Exposure to bioactive environmental particles and engineered nanoparticles are a significant public health concern. Inhalation of bioactive particles can result in chronic inflammation, which drives tissue remodeling and fibrosis. Furthermore, chronic inflammation can increase individual susceptibility to other diseases including cancer and autoimmune diseases. The macrophage is the critical cell in particle clearance following exposure, and is central to the inflammatory responses and tissue remodeling. Phagocytosed bioactive particles within macrophages cause cytotoxicity and activation of the NLRP3 inflammasome, outcomes that are both essential to inflammation and disease development. However, mechanisms that regulate NLRP3 inflammasome activity and cytotoxicity have not fully …

Close Call With Nonexistence: A Memoir, Jeff Gailus

Graduate Student Theses, Dissertations, & Professional Papers

Fred Eduard Gailus was born on April 26, 1944, in Memelland, a place that no longer exists. It was a tiny sliver of Germandom on the far eastern edge of Hitler’s outsized German Reich. When the Soviet Red Army swept through on their way to Berlin, to end World War Two and the reign of terror perpetrated by the German people, the homeland of my father’s ancestors was wiped off the map forever. Thanks to the courage and tenacity of his mother, Fred survived the largest forced migration in human history to marry young and raise a family of four …

An Evaluation Of The Effectiveness Of Eukaryotic Dna Extraction From Burial Soil Samples, Ariane Thomas

Graduate Student Theses, Dissertations, & Professional Papers

DNA is a valuable resource as a unique identifier of physical characteristics at both the population and individual levels. Due to a variety of factors that contribute to genetic decay, forensic and bioarchaeological investigators have limited outlets in which to extract viable DNA after most of a body’s organic materials have fully decomposed. This preliminary research focused on extracting DNA from the soil surrounding buried Sus scrofa domesticus cadavers to confirm the presence of viable and analyzable DNA. After a decomposition period of five months in Montana, soils were collected at incremental distances above the remains and sequenced to identify …

Crossing The Line: Navigating A Polluted Transboundary Watershed, Celia T. Tobin

Graduate Student Theses, Dissertations, & Professional Papers

Montana’s Lake Koocanusa sits at the end of a river system that drains Canada’s most productive coal country. Today, the waters of the massive lake contain a mineral called selenium, a poorly understood byproduct of mine waste. This summer, the U.S. federal government will be in a position to declare that the selenium in the lake puts Canada in violation of its international treaty with the U.S. The Montana government, however, is preparing to argue otherwise through its own water analysis. The disagreement has U.S. ecologists frustrated with the state’s position, saying they won’t practice science that is slave to …

Patient-Reported Variables Associated With The Success Of Behavioral Intervention For Patients With Chronic Cough, Bridget Loomis

This study is a small sub-set of a larger, ongoing study, which aims to create and validate a screening tool that primary care physicians can use in order to refer patients early and appropriately for medical or behavioral intervention.

Methods: In this prospective, exploratory study, 20 adult participants, aged 29-68 years of age, answered a bank of questions developed by an expert panel, and the Leicester Cough Questionnaire (LCQ), before and after BCT. Questions …

A Review Of Natural And Engineered Enzymes Involved In Bioethanol Production, Ines Cuesta Urena

Graduate Student Theses, Dissertations, & Professional Papers

Alternative petroleum-derived fuels, such as biofuels, is another form to decrease the dependence of non-renewable energy. The most promising alternative energy is cellulosic ethanol because of the abundance of cellulose and the overall lack of concern for the food-versus-fuel dilemma.

In order to produce ethanol from cellulosic materials, pretreatment is required to “open” the lignocellulosic matrix and make cellulose more susceptible to enzymatic degradation. Enzymatic hydrolysis of lignocellulose is an important area of research due to the absence of negative effects in downstream processes in comparison with acid hydrolysis. Both natural enzymes and engineered enzymes can be used in the …

Post-Discharge Outcomes For Youth Served In A Residential Treatment Center, Tara Lynne Smart

Graduate Student Theses, Dissertations, & Professional Papers

This causal-comparative non-experimental study explores the pattern of post-discharge functioning for youth who received either short term or long term residential treatment at Intermountain Children’s Home. Post-discharge functioning was evaluated using the Youth Outcome Questionnaire, 2.0 (Y-OQ 2.0) which tracked the behavioral and subjective experience of the youth, as well as their ability to function in society. Additionally, functional outcomes were also assessed post-discharge via phone interview questions about meaningful life domains. The researcher found that youth in both short and long term residential care experienced significant decreases in their Y-OQ 2.0 scores from admission to discharge, admission to 6 …

A Spark That Starts The Fire: Climate Change In The American West, Nathaniel Hegyi

Graduate Student Theses, Dissertations, & Professional Papers

Climate change is a large, unwieldy, global phenomenon that acts like a spark in a dry field. A slight rise in the global temperature weakens the Gulf Stream and sends the East Coast into a deep freeze. A slight dip in the global temperature, caused by a volcanic eruption, alters weather patterns and dumps record amounts of rain in Southeast Asia. The three stories in this portfolio depict how climate change can alter the landscape and people of the American West. Chapter one is a narrative summarizing these stories, my reporting process, and publication plans. Chapter two is an embedded …

Gender Nonconformity, Psychosocial Stressors, And Psychopathology: Looking Beyond Sexual Orientation, Kathryn M. Oost

Graduate Student Theses, Dissertations, & Professional Papers

LGBT individuals experience disproportionately more victimization than their heterosexual and cisgender counterparts. Within these populations, perceived gender nonconformity predicts even higher rates of victimization. The current investigation examined relationships between gender nonconformity, experiences with victimization, and psychopathology among 671 students from the University of Montana, including 64 LGBT-identified individuals, who took part in an online study as part of course requirements. Hierarchical regressions were calculated to examine the relationships between gender expression, victimization, and psychopathology while controlling for sexual orientation, gender identity, and ethnicity. Gender nonconformity was a significant predictor of reported victimization, beyond sexual orientation and ethnicity (ΔR …

“The Most Poisonous Of All Diseases Of Mind Or Body”: Colorphobia And The Politics Of Reform, April J. Gemeinhardt

Graduate Student Theses, Dissertations, & Professional Papers

Focusing on the mid-1830s through 1865, this thesis explores colorphobia—the irrational fear and hatred of black people otherwise known as racial prejudice—as a reform tactic adopted by abolitionists. It argues that colorphobia played a pivotal role in the radical abolitionist reform agenda for promoting anti-slavery, immediate emancipation, equal rights, and black advancement. By framing racial prejudice as a disease, abolitionists believed connotations, stigmas, and fears of illness would elicit more attention to the rapidly increasing racial prejudice in the free North and persuade prejudiced white Americans into changing their ways. Abolitionists used parallels to cholera, choleraphobia (fear of cholera), and …

Bicycle Mobility In Glacier National Park: Assessing Going-To-The-Sun Road Travelers' Attitudes, Knowledge, And Perceptions Of Bicycling, Brian G. Battaglia

Graduate Student Theses, Dissertations, & Professional Papers

The central aim of this thesis assessed whether Going-to-the-Sun Road (GTSR) travelers have a positive or negative association with roadway bicycling and the degree of public support for GTSR bicycling in Glacier National Park (GNP). Secondarily, this thesis tested a control and treatment group’s knowledge of roadway cycling laws to determine the effectiveness of a “Bicycles May Use Full Lane” sign and brochure, which both reflected Montana’s cycling laws. Finally, an analysis of the necessity of GNP’s partial bicycle restriction on the GTSR was conducted by comparing the characteristics of two road segments using GIS, and by assessing the attitudes, …

Beyond Blood: Examining The Communicative Challenges Of Adoptive Families, Mackensie C. Minniear

Graduate Student Theses, Dissertations, & Professional Papers

This study examined how adoptive families discursively create family identity through their communication. Building on theories of discourse dependence and family communication patterns, this research examined how families whose identity does not meet a bio-genetic view of family must re-define family using communication. Often times, families that are created outside biological means must renegotiate family identity both within the family, and outside the family, from those who feel comfortable commenting and questioning their family composition. Communication becomes a tool that adoptees must use to understand their family identity, as well as their own adoptive identity. Furthermore, this study looked to …

POSTACTIVATION POTENTIATION PRACTICAL IMPLICATIONS IN THE COLLEGIATE SETTING

Chairperson: Matthew Bundle Ph.D.

Postactivation potentiation (PAP) induced by a voluntary conditioning activity (CA) has been shown to increase peak force and rate of force development during subsequent muscle contractions increasing performance. We examined existing PAP literature, the underlying physiological mechanisms responsible for PAP, and the various factors that affect protocols used to elicit the PAP response. Furthermore, we aimed to determine what combination of factors are optimal for eliciting a PAP response in training and competition. The proposed mechanism underlying …

Performance Measures Of Road Crossing Structures From Relative Movement Rates Of Large Mammals, Adam Andis

Graduate Student Theses, Dissertations, & Professional Papers

In recent decades, there has been an increase of engineering projects that seek to mitigate the barrier effect roads impose on wildlife by installing wildlife crossing structures that promote permeability of the road corridor. The 41 fish and wildlife crossing structures installed along a 90km stretch of US Highway 93 on the Flathead Indian Reservation in western Montana, represent one of the most extensive of such projects in North America. As mitigation efforts are increasingly considered and implemented in road construction projects, the need to assess these structures’ effectiveness grows. This study is the first to compare observations of animal …

Redskins Revisited: Competing Constructions Of The Washington Redskins Mascot, Eean Grimshaw

Graduate Student Theses, Dissertations, & Professional Papers

This project looks at how synecdoche and ideographs function in the construction of competing position in the controversy surrounding the Washington Redskins mascot. I examined the rhetoric produced by both the Washington Redskins organization and its fans, as well as the rhetoric of Change the Mascot, the Oneida Indian Nation of New York and other opponents between the years of 2013 and 2015. Based in part on Moore’s (1993, 1994, 1997) argument that synecdoche and ideographs often prevent resolution and produce irreconcilable conflict, I extend this notion insofar as the controversy surrounding the Redskins mascot appears to be shifted towards …

Preschool Writing Instruction: Modeling The Writing Stages, Shelby Swant

Graduate Student Theses, Dissertations, & Professional Papers

Writing is an essential component of language development and early literacy. With the growing focus on national and state education standards, the early foundation of writing and literacy skills proves to be an area of importance and concern; however, limited research has been conducted in the area of preschool writing instruction. This study investigated writing and other foundational literacy skills in preschoolers following three different instructional conditions. Preschoolers (n=85), who attended a preschool educational setting serving low-income families, were randomly assigned to classrooms in three research groups: control, comparison, and treatment. The control group participated in implicit writing …

Temporary Work On The Bakken Shale, Peter D. Ore

Graduate Student Theses, Dissertations, & Professional Papers

In this thesis, I explore what accounts for worker consent to precarious employment in the context of rapid industrial change in the rural United States. In recent years, domestic oil development has transformed the landscape of western North Dakota and Eastern Montana into a zone of oil production now known as “the Bakken.” The acute demand for labor brought about by this development resulted in vastly inflated wages, which in turn drew workers from around the U.S. and the world. State and private labor market intermediaries, including temporary labor agencies, formed to organize and market this labor force for employers …

Exploring The Potential For Geographic Transportation Modeling To Improve Food Assistance: A Case Study Of The Missoula Food Bank, Mary Buford French

Graduate Student Theses, Dissertations, & Professional Papers

Over the last ten years, the Missoula Food Bank has seen a greater need for its services leading to funding shortfalls. To meet the needs of an increasing number of clients with a limited budget, the Missoula Food Bank must look for ways to modify its operations while increasing efficiency of its services. As the Food Bank budget is used to acquire food and currently also transport it from warehouse locations to the food pantry in a crowded space, reducing distances and transport cost of hauling food would in turn free up funds to obtain more food. At the same …

The Western Stemmed Point Tradition: Evolutionary Perspectives On Cultural Change In Projectile Points During The Pleistocene-Holocene Transition, Lindsay D. Scott

Graduate Student Theses, Dissertations, & Professional Papers

In this thesis I analyze the cultural techniques of Paleoindians in North America by examining the diversification and fusion of stemmed projectile point traditions using an evolutionary analysis. The Western Stemmed Point tradition has an extensive regional and temporal distribution throughout the Intermountain West and High Plains during the Paleoindian period. In an effort to determine how stemmed projectile point technologies relate to each other, I applied a phylogenetic approach to construct heritable patterns of projectile point histories. By measuring the physical traits of those points and using a macro-evolutionary theoretical approach, changes in artifact form can be acquired and …

Knife River Flint Distribution And Identification In Montana, Laura Evilsizer

Graduate Student Theses, Dissertations, & Professional Papers

An examination of the spatial, temporal, and functional distribution of Knife River flint in Montana, and a study in misidentification of Knife River flint in archaeological assemblages. Lithic sourcing has the potential to provide a plethora of information to archaeologists: resource procurement strategies, mobility patterns, trade networks, and the preferencing of particular lithic material types. However, without proper identification it is impossible to study the distribution of lithic materials from their source. Knife River flint, a brown chalcedony, is a particularly fascinating material, geologically occurring in a small area, but culturally distributed over a large area. I analyze the distribution …

Another Day In The Oil Patch: Narratives Of Probation Work In Montana, Ally Guldborg

Graduate Student Theses, Dissertations, & Professional Papers

Job stress has been linked to several negative outcomes for workers in human service professions. Despite a wealth of knowledge on job stress in social service occupations, relatively little is known about the job stress of probation officers. In eastern Montana and western North Dakota’s Bakken region, a recent oil extraction boom and bust cycle has caused rapid socio-demographic change. Researchers have found that oil extraction in the Bakken region has led to several challenges for social service and police agencies in the area. In this study, I use qualitative interview methods to examine the stresses and challenges involved in …

Exploring Park Support: A Study Of Philanthropy And Other Support For Yellowstone National Park, Geoffrey G. Havens

Graduate Student Theses, Dissertations, & Professional Papers

Support for charitable causes has long been a topic studied in the hopes of uncovering the reasons for donations and other support behaviors. However, holistic examination of support for places, such as parks, has been relatively untouched as an area of research. One such place where understanding such support is important is Yellowstone National Park, the first designated National Park and one of the most visited parks in the United States. A lack in adequate government funding to meet increasingly heavy visitation has led the park to increasingly rely on outside support for the park.

The purpose of this study …
