Efficacy Of Three Backward Masking Signals, Robert David Sears

Graduate Student Theses, Dissertations, & Professional Papers

Increased backward masking has been correlated with Auditory Processing Disorders (APD). An efficacious test of the backward masking function that is compatible with naïve listeners could have clinical utility in diagnosing APDs. In order to determine an appropriate probe for such a test, three 20-ms signal-types were compared for ease-of-task. Response times (RT) were taken as a proxy for ease-of-task. Seven participants used a method-of-adjustment to track threshold in the presence of a 50-ms broadband-Gausian-noise backward-masker. The signal-types yielded two comparisons: Linear rise-fall on a 1000Hz sine-wave versus a “chirp” (750 Hz-4000Hz); Linear rise-fall vs Blackman gating function on a …

Better Talking Heads: Concerning Fuller "Experience" In Environmental Philosophy, Christina Bovinette

Graduate Student Theses, Dissertations, & Professional Papers

Through this project, I demonstrate how professional environmental ethics is constrained by, what I call, a rationalist bias and I offer a different approach to environmental questions in the face of this observation. Intellectual life depends on material conditions and our necessary physical ties to Earth. I suggest that an emphasis on our physical connections with the planet can benefit professional environmental ethics. I draw from some feminist understandings to discuss the advantages of a professional environmental ethics that respects and integrates experiences outside of rational deliberation. I attempt to bring my discussion of experience, environmental ethics, and some feminist …

Individuals’ Perceptions Of Disordered Eating Pathology: Development And Validation Of The Inventory For Disordered Eating Attributions (Idea), Lindsay Katherine Crosby

Graduate Student Theses, Dissertations, & Professional Papers

Eating pathology may be triggered by a number of biological, environmental, personal, and social experiences. Research in the field of disordered eating has uncovered numerous intrinsic and extrinsic vulnerabilities to developing abnormal eating behavior, and these etiologies often impact the onset, severity, type, and prognosis of disordered eating behavior in varying ways. Further, a limited number of measures have been created to examine individualsÆ beliefs about why they are experiencing various mental health conditions (e.g. reasons for depression, developing substance dependence, etc.), which has implications for tailoring assessment and intervention. However, there is currently no such measure for individuals experiencing …

Chillisource Game Engine Particle System Study, Angela Gross

Graduate Student Theses, Dissertations, & Professional Papers

The majority of modern game engines utilize intricate objects called particle systems which are a collection of many particles that together represent an object without well-defined surfaces. This thesis discusses the results of studying and stressing particle systems within ChilliSource, an open-source game engine written in C++, with the goal of understanding a complex system and exploring possible optimizations that could be made to it. The studies performed were driven by metrics generated with custom profiling classes that kept track of things like the number of particles rendered, how long the engine spent rendering particles, or even how long a …

Autobiographical Memory Of Nature-Based Tourists: Formation Of Place Attachment And Influences On Visitor Behavior, Jacob Daniel Jorgenson

Graduate Student Theses, Dissertations, & Professional Papers

The National Park Service (NPS) is currently beginning the celebration of 100 years as a formal agency. Yellowstone National Park, the world’s 1st national park, catered to over 4 million visitors during 2015. Visitation is rising, but there are underlying issues that are highlighted in a recent guiding document; Revisiting Leopold (2012). Congressional budgets are decreasing, younger generations are losing interest in nature, and diverse populations have yet to become fully vested in the NPS. Realizing these pressing issues, Yellowstone sought to understand ways in which visitors can support the park and how to engage visitors to create long-lasting relationships. …

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 …

Graduate Student Theses, Dissertations, & Professional Papers

Leaders remain perpetually connected to their work because of the rapid advancement of information technology. This research, using a qualitative approach, explored how increased connective technology is affecting school leaders with the central question: How is hyperconnectivity experienced by school leaders? Using personal interviews, the lived experiences of fifteen international middle and high school principals with one-to-one student-to-device programs were collected. Raw transcriptions of their experiences were analyzed using the descriptive phenomenological approach as outlined by Giorgi (2009). This approach allowed for the data to be reduced into a single narrative description shared by all participants indicating the essences of …

Modulating Male Aggression And Courtship: Detecting External Pheromonal And Nutritional Information, Jonathan C. Andrews

Graduate Student Theses, Dissertations, & Professional Papers

Survival and reproduction in the natural world requires an organism to identify and react to the presence of environmental stimuli in a time and cue dependent manner. Such temporal specificity requires the development and use of specialized sensory organs that receive this external sensory information. Neurons within the specialized sensory organs respond to touch, taste, pheromones, chemicals, and light, and transduce this information to the central brain. In many systems, gustatory and olfactory chemosensation in particular, provides critical information regarding sex and species identification as well as the status of food resources. The output of neurons which receive chemical information …

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 …

Examining The Feasibility Of A Rural School-Family Initiative, Heather M. Halko

Graduate Student Theses, Dissertations, & Professional Papers

Increased prevalence of child psychological difficulties demonstrates a need for feasible mental health interventions that are available to children and families. Previous research shows evidence for the effectiveness of family-focused, school-based mental health programs in addressing child academic and behavioral problems. However, various barriers exist that prevent such programs from being implemented with fidelity: ability to identify high-risk children and families; school staff and caregiver attitudes, motivation, and satisfaction regarding use of the program; and program costs. The current study examined the feasibility of a rural school-family initiative that contained aspects of the Positive Family Support (PFS) program, including an …

Graduate Student Theses, Dissertations, & Professional Papers

Depression rates are high among adolescents, yet most young people do not receive treatment. Alternatives to in-person treatment are needed which are cost-effective and widely accessible. Teens use technology at high rates, but innovative methods of online treatment have not been widely researched in the United States. MoodGYM is a free, internet-based program designed to prevent depression in adolescents which has shown promise in research studies in Australia. To date, no studies with MoodGYM have been published in the United States. This pilot study was designed to evaluate the acceptability of usage of MoodGYM at home by adolescents to treat …

Political Ecology Of Cordyceps In The Garhwal Himalaya Of Northern India, Laura Bess Caplins

Graduate Student Theses, Dissertations, & Professional Papers

In the Garhwal, Indian Himalaya, rural mountain people labor to piece together their livelihoods in an ever changing world. One particular group, the Bhotiya (an ethnically and culturally distinct tribal group) were historically engaged in seasonal migration (i.e. transhumance) to take advantage of scarce mountain resources and trade relations with Tibet. This livelihood practice has all but disappeared; however, today one way the Bhotiya are adapting to these changing circumstances is by engaging in the collection and sale of a valuable alpine medicinal fungus locally known as keera jari, and commonly called the caterpillar fungus or cordyceps (Ophiocordyceps sinensis). The …

Determining The Barriers To And Opportunities For Community Involvement In The Management Of The Nanda Devi Biosphere Reserve, Uttarakhand, India, Trisha Singh

Graduate Student Theses, Dissertations, & Professional Papers

Today’s global political environment places a high value on social equality and economic well- being. In this climate, emphasizing biodiversity conservation over socio-economic development through exclusionary methods of habitat protection has become ethically questioned and politically dangerous. The goal of this research was to understand the barriers and opportunities for local involvement in the management of the Nanda Devi Biosphere Reserve in Uttarakhand, India. We attempted to understand the feasibility of local community involvement in the management of the NDBR from the perspective of policy-making organizations and that of the local communities.

Key findings highlight barriers to community participation at …

Conservation Genetics On The Frontline, Kenneth W. Rand

Graduate Student Theses, Dissertations, & Professional Papers

Conservation genetics stands out as an effective tool for discovering and monitoring rare, endangered or invasive populations of plants and animals. Particularly when compared to traditional search and capture methods, it provides more holistic studies to preserve the disappearing biodiversity of the American West and the world.

Three stories highlight the work done to preserve biodiversity through the use of conservation genetics:

1. Trout Rescue: A new hope for westslope cutthroat in Montana How to save a disappearing westslope cutthroat trout through genetic rescue by adding genetic diversity to ensuring future survival in increasingly warming waters more harm than good. …

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 …

It’S Rooted In The Land: How Managing Natural Resources Leads Native American Tribes To Sovereignty, Nicky Ouellet

Graduate Student Theses, Dissertations, & Professional Papers

Tribal management of land and natural resources within the boundaries of Native American reservations is often superseded by state and federal policy. But control of land and resources is, ultimately, what makes a nation a nation. The three stories in this portfolio depict tribes establishing control of natural resources to various degrees of success. Chapter one is a narrative outlining the stories, my reportage and plans for publication. Chapter two: Members of the Northern Cheyenne seek to establish a medical marijuana program after the federal government relaxed enforcement of cannabis bans. Chapter three: An activist on the Fort Berthold reservation …

Cyber-Victimization And Delinquency: A General Strain Perspective, Ian D. Greenwood

Graduate Student Theses, Dissertations, & Professional Papers

This study examines juvenile delinquency and cyber-victimization from a general strain perspective. General strain theory provides a model where strain is experienced through the (1) loss of something valued, (2) the presentation of noxious stimuli, or (3) the inability to achieve valued goals. As a coping mechanism for strain, some juveniles react through criminal or delinquent behavior. This thesis predicts that cyber-victimization increases the likelihood of physical fighting, weapon-carrying, and truancy at school. Using the 2013 National Crime Victimization Survey: School Crime Supplement, the hypotheses are analyzed using multivariate logistic regression models that include other known correlates of delinquency. Marginal …

Ecology Of The Alluvial Aquifer Of The Nyack Floodplain On The Middle Fork Of The Flathead River, Montana, Amanda Gay Delvecchia

Graduate Student Theses, Dissertations, & Professional Papers

The pristine Nyack Floodplain on the Middle Fork of the Flathead River in Northwestern Montana contains an expansive alluvial aquifer that is extremely limited in organic carbon, yet supports abundant and diverse hyporheic stoneflies.

This quantitative dissertation study explored the social media practices and perceptions of 452 leaders of 142 public and private non-profit four-year degree granting institutions in the western United States. Descriptive statistics were calculated for gender, position title, age, social media use, and attitudes regarding themes revealed in a review of current literature. Then, a Spearman Rho analysis was used to measure the strength of correlation between hours using social media and rank scores of social media attitudes. The study revealed that about 85% of leaders use social media for an average of 4.54 hours per week (SD=5.59, N=452). Social media …

Old Wet Paint, Michael G. Hansen

Graduate Student Theses, Dissertations, & Professional Papers

Contemporary living can cause stress that is detrimental to creativity. Most of the world’s population has grown dependent on technology to connect us to, and keep track of daily, monthly, and hourly actions. Our plans fill us with the illusion of control over random events. I do not trust technology to help me find my way in the world. I want to find my way in life using limited technology. My art practice is an example of this trajectory and has become my way of embracing random events. The logic I use to employ order in the pandemonium of everyday …

School Supports For Lgbtq Students: Counteracting The Dangers Of The Closet, Lauri Mae Lindquist

Graduate Student Theses, Dissertations, & Professional Papers

Researchers have reported that being proud and open about one’s sexual and/or gender identity is related to fewer negative psychological outcomes. However, this process of identity development is often impeded by environmental factors, such as minority stress. Through his minority stress hypothesis, Meyer (2003) suggests that suggests that living in a society that is intolerant of central features of the self (e.g., sexual orientation and gender identity) increases the level of stress in individuals with minority statuses. These environmental stressors are consistently shown by research to account for the disproportionate amount of negative psychological and academic outcomes experienced by sexual …

Landscape To Local: A Multi-Scale Evaluation Of Voluntary Efforts To Reduce Fragmentation And Enhance Management Of Rangelands For Sage-Grouse, Joseph Tyler Smith

Graduate Student Theses, Dissertations, & Professional Papers

For imperiled species, the hierarchical nature of habitat selection suggests the need for a hierarchical approach to conservation: address threats to persistence operating at broad scales on populations before focusing on the quality of patches or availability of particular resources used by individuals. We apply this approach to conservation and management of habitat for greater sage-grouse (Centrocercus urophasianus) in the eastern portion of their range where cropland conversion continues to fragment sagebrush grasslands. Using locations of active leks in portions of Montana, Wyoming, North Dakota, and South Dakota as spatial indices of populations, we found sage-grouse distribution was highly sensitive …

Impacts Of Recreational Aviation On Wildlife: The Physiological Stress Response In White-Tailed Deer (Odocoileus Virginianus) And Associated User Perceptions, Devin W. Landry

Graduate Student Theses, Dissertations, & Professional Papers

Recreational aviation on public lands may negatively impact wildlife. However, land-use decisions need to balance user need with wildlife impact. We know very little about 1) how back country airstrip use affects local wildlife, or 2) attitudes and perceptions of recreational pilots toward possible management actions. For my Master’s research, I investigated how aircraft activity influenced physiological measures of stress in white-tailed deer, while also modeling how psychometrics such as wildlife attitudes and place attachment predict the willingness of recreational pilots engage in impact-mitigating behaviors. I measured physiological stress through non-invasive sampling of stress hormones in fecal samples (fecal glucocorticoid …

Cold Lapse, Tressa Jones

Graduate Student Theses, Dissertations, & Professional Papers

cold lapse addresses the abstract notions of time and loss while conveying the value of observing the present. The postmodern view of time, the grid’s vernacular, and the aesthetics of postminimalism are my foundation for communicating time’s passage and its consequential sensations of absence. The duration of a slow drip, the cycle of breath and the sequential motion of a hand folding paper each mark passing moments. By observing these signs the phenomenon of time may be appreciated. Care and ephemerality in the work require the viewer’s sensitivity when encountering and witnessing it, much like the demands of observing the …

Synthesis Of Satellite Microwave Observations For Monitoring Global Land-Atmosphere Co2 Exchange, Lucas Alan Jones

Graduate Student Theses, Dissertations, & Professional Papers

This dissertation describes the estimation, error quantification, and incorporation of land surface information from microwave satellite remote sensing for modeling global ecosystem land-atmosphere net CO₂ exchange. Retrieval algorithms were developed for estimating soil moisture, surface water, surface temperature, and vegetation phenology from microwave imagery timeseries. Soil moisture retrievals were merged with model-based soil moisture estimates and incorporated into a light-use efficiency model for vegetation productivity coupled to a soil decomposition model. Results, including state and uncertainty estimates, were evaluated with a global eddy covariance flux tower network and other independent global model- and remote-sensing based products.
