Using Auditory Evoked Potentials To Objectively Determine Backward Masking, Brittany Galvin, Allie Cope

University of Montana Conference on Undergraduate Research (UMCUR)

Backward Masking (BM) functions have been shown to relate to age, lead toxicity, and how they differentiate in children with language disorders. A number of studies have been done that support BM related to auditory processing deficits. This has been shown in both animal models and human studies. This proposed study will be used to see if Evoked Potentials (EP) could be utilized to obtain BM functions. A tonal stimulus, followed by an inter-stimulus interval (ISI) and a noise masker were combined to make the EP stimulus. All segments were studied individually in the appropriate temporal alignment. ISI’s of various …

Auditory Processing In Fluency Disorders, Harley B. Kincheloe

University of Montana Conference on Undergraduate Research (UMCUR)

One possible cause of stuttering could be related to Auditory Processing Disorders (APD). However, at the present time there are few research studies that are able to support the relationship of APD and stuttering. One suggested link between auditory dysfunction and stuttering is that the poorer auditory processing scores by stutters reflect a basic auditory deficit, which interferes with fluency because speech is monitored through auditory feedback. The first technique to study binaural masking is the Masking Level Difference (MLD). The MLD is the difference between the SoNo and the SpNo binaurally masked thresholds. For the SoNo condition noise stimuli …

Analysis Of The Activity Areas And Cleaned Zones Of Floor Iib Of Housepit 54 At The Bridge River Site (Eerl4), Nicole Musci

University of Montana Conference on Undergraduate Research (UMCUR)

The Bridge River Archaeological Project has been active since 2003 and consists of a collaborative partnership between The Department of Anthropology at The University of Montana, and Xwisten, the Bridge River Indian Band. Since the beginning of the project numerous studies and excavations have been conducted in the Bridge River area to develop an understanding of the ancient history of the area focusing on the ancient peoples who lived there during the past 2000 years. This project involves utilizing “heavy fractions,” which are rock and bone materials left over from a process that separates “light fraction” materials (such as botanicals), …

Defining An Agency: Animals, Fire, And The U.S. Forest Service, Ellen A. Ipsen

University of Montana Conference on Undergraduate Research (UMCUR)

Today, the United States Forest Service has established itself as an enduring authority on federal lands management. However, in 1905 when the federal government established the agency, its fate was far from secure. Prior to 1905, people living in the West had unchecked access to public land resources and many disapproved of an expansion of federal power. It was the issue of forest fire fighting that gained public support for the agency, and animals, in large part, helped them succeed. Horses and mules were used for transportation, scouting missions and trail building before adequate technology existed. Every ranger was required …

Factors Influencing Mountain Lion Kill Rates, Steven Cross

University of Montana Conference on Undergraduate Research (UMCUR)

Kill rate, defined as the number of prey killed per predator per unit time, is a key component to understanding predator-prey dynamics. A multitude of factors may affect kill rates, including, variation in age, sex, weight, or presence of offspring of either predator or prey species (intraspecific variation) and events such as the theft of a kill made by another animal (kleptoparasitism). These factors may influence the time a predator spends locating prey (search time) and the pursuing, killing, and consumption of prey (handling time). The sum of search time and handling time may be measured as the time between …

Respiratory Function Within A Novel Dystrophic Mice Model, Ronald T. Gallegos, Tiffany Quindry, Josh T. Selsby, John Quindry

University of Montana Conference on Undergraduate Research (UMCUR)

Respiratory Function Within a novel Dystrophic Mice model

Purpose: Duchene Muscular Dystrophy (DMD) is a genetic disease resulting in progressive heart and skeletal muscle degeneration. The disease is characterized by inadequate dystrophin content in muscle cells. With no known cure, it’s essential to discover a medical intervention for DMD pathology. This research group explored variations of a nutritional based therapy as a potential treatment to DMD pathology, including respiratory dysfunction. Early results suggest that dietary quercetin supplementation may improve respiratory function but strategies for maximizing quercetin efficacy are needed. In this investigation respiratory function was examined following a new dietary …

The Effect Of Visual Social Stimuli On Octodon Degus, Danielle Crandell

University of Montana Conference on Undergraduate Research (UMCUR)

Most vertebrates have evolved to recognize potential predators, prey, and social partners, but very little is known about how the brain detects and responds to such agents. One difficulty is experimentally controlling for cues that might signal agency, particularly in experimental models such as mice, which depend heavily on olfaction. We sought to test whether a more visual rodent, the diurnal, Chilean degu, would be differentially attracted or averse to social compared with non-social visual stimuli. Degus were placed in a chamber containing four, 3D printed objects made from white polylactic acid (PLA). Two objects were shaped as quadruped animals, …

Integrating Cellular Percolation Fire Spread Into An Existing Landscape Model, Michael D. Kinsey

University of Montana Conference on Undergraduate Research (UMCUR)

The U.S. Forest Service uses the Simulating Patterns and Processes at Landscape Scales (SIMPPLLE) application to simulate landscape ecological processes and evaluate treatment options on National Forests in Montana, Northern Idaho, and the Dakotas. Wildfires are an influential process on the landscape; therefore, the model must accurately simulate ecological processes over long time periods. OpenSIMPPLLE, an open-source version of SIMPPLLE, contains an algorithm that spreads fire in all directions, regardless of wind and elevation, resulting in rectangular fires, which does not reflect realistic fire behavior. We integrated a more accurate cellular percolation spread algorithm developed by Keane et al. (2006) …

Eaat This: How Eaat1 Knockdown In Astrocytes Alters Aggression In Drosophila Melanogaster, Haley N. Shepard

University of Montana Conference on Undergraduate Research (UMCUR)

How behavior and information is encoded in brain circuits and how individual neurons influence these brain circuits is a growing question in neuroscience. In the nervous system of many organisms, including humans and Drosophila, exists a subset of neurons that are capable of releasing more than one neurotransmitter, a phenomena called co-transmission. How co-transmission may alter circuits dedicated to behavior is a challenging question. To begin to answer this question we used the genetic tools available in Drosophila to investigate how the release of two neurotransmitters from a single neuron can alter aggression. Astrocytes surround the synapses of neurons …

Vulnerable Vietnam: Climate Change In The Mekong Delta, Lione Clare

University of Montana Conference on Undergraduate Research (UMCUR)

My “Vulnerable Vietnam: Climate Change in the Mekong Delta” photography storytelling project is an effort to communicate the significance of climate change effects on the people and environment of the Mekong Delta in a creative and effective way. It will not only focus on the effects of climate change in the Delta, but also include current adaptation and mitigation strategies.

The visual presentation of this project is still in progress, but the research was conducted during my recent time in Vietnam as part of the “Wintersession in Vietnam” study abroad program. In Vietnam, I learned about current and projected effects …

Scene Of A Changing Climate, Mona Nazeri Dr

Graduate Student Portfolios, Professional Papers, and Capstone Projects

For the last 500,000 years, the world climate has been in transition from warm to cold and vice versa. However, recent human-caused climate change has increased the rate of change in extreme and average climate conditions. Globally, people are facing higher than average temperatures as well as accelerated rates of drought and flooding. According to the Intergovernmental Panel on Climate Change (IPCC,) natural systems around the globe are being affected by regional climate change, mainly temperature increases. They IPCC found that 20-30% of plant and animal species are likely to be at increased risk of extinction if global average temperatures …

Taking A Bite Out Of Unwanted Data In The Animal Bite Syndrome, Erika Baldry, Tracy Miller, Jill Baber

UM Graduate Student Research Conference (GradCon)

Introduction. North Dakota collects syndromic surveillance data, de-identified reason-for-visit data, for all visits to participating emergency departments (EDs), walk in clinics, and ambulatory clinics throughout the state. Syndromic data is submitted daily and automatically through an electronic connection between health care providers and the state. Animal bites are not required to be specifically reported to the North Dakota Department of Health (NDDoH) by providers; however, NDDoH has utilized North Dakota’s syndromic surveillance program, BioSense 2.0, for routine surveillance by using an existing animal bites syndrome. We sought to evaluate the existing BioSense 2.0 animal bites syndrome and explore how the …

Fighting the Rape Culture Wars Through the Preponderance of the Evidence Standard

Rape By Malice, Kari Hong

Montana Law Review

When people seek to reform rape law, the focus is on changing the actus reus—either abandoning the force element or redefining consent. This article argues that both approaches overlook a critical opportunity for reform, which is the crime’s mens rea. Knowledge, or general intent, is the most common mens rea in rape offenses. The problem with this mental state is that proving what a defendant knew is one of the hardest parts of any criminal prosecution. Although scholars have explored reckless or negligent standards, this article proposes that states adopt the mens rea of malice—a callous indifference towards the risk …

Multi-Scaled Approaches For Protecting Montana's Watersheds And Water Resources, Elizabeth Yoder

Graduate Student Portfolios, Professional Papers, and Capstone Projects

The central theme carried among my four portfolio pieces is: using scientific and governmental approaches to conserve watershed health. For the purposes of this portfolio, I define watershed health as a very general term that describes the state of water quantity and quality that is available for human and ecosystem needs in a watershed. I see each of my portfolio pieces focusing on a different scale and method (i.e., science or government, including different levels of government, local, state and federal) for conserving watershed health. My first portfolio piece reviews water quality degradation caused by pharmaceuticals and personal care products …
