Social-Ecological Soundscapes: Examining Aircraft-Harvester-Caribou Conflict In Arctic Alaska, Taylor R. Stinchcomb

Biological Sciences

As human development expands across the Arctic, it is crucial to carefully assess the impacts to remote natural ecosystems and to indigenous communities that rely on wild resources for nutritional and cultural wellbeing. Because indigenous communities and wildlife populations are interdependent, assessing how human activities impact traditional harvest practices can advance our understanding of the human dimensions of wildlife management. Indigenous communities across Arctic Alaska have expressed concern over the last four decades that low-flying aircraft interfere with their traditional harvest practices. For example, communities often have testified that aircraft disturb caribou (Rangifer tarandus) and thereby reduce harvest opportunities. Despite …

Evaluation Of Effectiveness And Cost-Benefits Of Woolen Roadside Reclamation Products, Rob Ament, Eli Cuelho, Monica Pokorny, Stuart Jennings

CESTiCC Project Reports

This research project developed three types of products for study: woolen erosion control blankets (ECBs), wool incorporated into wood fiber compost at a 40:1 ratio (compost to wool, by weight), and wool incorporated into silt fence. The project, supported by Montana Department of Transportation (MDT) and the Center for Environmentally Sustainable Transportation in Cold Climates, compared the wool products’ performance to roadside reclamation products commonly used for revegetating cut slopes: straw/coconut (coir) ECB, wood fiber compost and woven plastic silt fence. Three versions of wool silt fence were developed by the project, yet, even more versions are needed to arrive …

The Role Of Brain Stem 5-Ht1a And Gaba-A Receptors In The Thermoregulatory Response To Hypoxic Stress, Alexander Schmidt

Senior Honors Projects, 2010-2019

Sudden Infant Death Syndrome (SIDS) is a leading cause of infant mortality. Alterations in brainstem development of Serotonin (5HT) and γ-aminobutyric acid (GABA) are linked to its cause. The sympathetic premotor neurons located in the Nucleus of the Raphe Pallidus (NRP) in the brainstem have both 5-HT1A and GABA-A receptor subtypes that mediate protective cardiovascular responses to environmental stress. It is hypothesized that alteration in these receptors at the NRP will also modify protective thermoregulatory responses to hypoxic stress such as hypothermia. Using aseptic techniques, male and female Sprague-Dawley rats (230-385g) were instrumented with radiotelemetry probes to non-invasively measure core …

Pathological Personality Traits And Neuropsychological Function, Rui Tang

Psychology Theses and Dissertations

Traditional categorical diagnosis in DSM-5 has received widespread criticism due to its extreme heterogeneity, poor diagnostic reliability, poor validity and high comorbidity. The alternative trait model introduced the domain of psychoticism, which captures the trait of positive schizotypy. Positive schizotypy has been linked to vulnerability to schizophrenia spectrum disorders, which has shown several areas of neuropsychological dysfunction. Considerable evidence has demonstrated that the dimensional model has superior reliability and validity and ties to important clinical constructs such as neuropsychological function. Little research has tied the dimensional model of personality pathology to neuropsychological domains including processing speed and executive function. The …

Soil Morphological, Physical, And Chemical Parameters Affecting Longleaf Pine (Pinus Palustris) Site Quality And Ecosystem Restoration Potential In East Texas, Ryan Svehla, Kenneth W. Farrish

Electronic Theses and Dissertations

There has been a large decline in coverage of longleaf pine (Pinus palustris Mill.) within its range in the southeastern United States since the time of European settlement. Due to this decline, interest has developed in the re-establishment of this species on suitable sites. However, many attempts have been unsuccessful in re-establishment, likely in part due to the lack of emphasis on selection of suitable soils. Historically, longleaf pine was found on soils with a wide range of soil properties, including higher quality soils, due to frequent fires which kept many competing species suppressed. Decline in longleaf pine coverage …

The Mediating Role Of Trauma Symptoms In Teen Dating Violence Victimization, Caitlin Rancher, Ernest Jouriles, Renee Mcdonald, Jeff Temple, David Rosenfield

Psychology Theses and Dissertations

This research examined whether the frequency of recent physical and sexual teen dating violence (TDV) victimization is associated with re-experiencing, avoidance, and hyperarousal trauma symptoms, and whether they, in turn, predict the frequency of future TDV victimization. Participants were 104 (49% female) 14 to 17 year olds, recruited primarily from truancy courts to participate in three assessments, spaced three months apart. Adolescents reported on their trauma symptoms, experiences of physical and sexual dating violence victimization and characteristics of their romantic relationship at every assessment. Results indicated that the frequency of recent TDV victimization is related to re-experiencing, avoidance and hyperarousal …

Rgb Image-Based Pupillary Diameter Tracking With Deep Convolutional Neural Networks, Chatchai Wangwiwattana

Computer Science and Engineering Theses and Dissertations

Pupillary diameter monitoring has proven successful at objectively measuring cognitive load. This work presents three robust RGB video based pupillary diameter trackers and compares them for measuring cognitive load using commodity cameras. We investigate the use of modified starburst algorithm from previous work and propose two algorithms: 2-Level Snakuscules and a convolutional neural network which we call PupilNet. Our results show PupilNet outperforms other algorithms in measuring pupil dilation, is robust to various lighting conditions, and robust to different eye colors. In addition, this work explores various deep learning architecture for extracting the pupillary response as well as understand the …

Brain Motion, Deformation, And Potential Injury During Soccer Heading, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Working Papers

This paper addresses the problem of what is happening physically inside the skull during head-ball contact. Mathematical models based upon Newton’s laws of motion and numerical methods are used to create animations of brain motion and deformation inside the skull.

Initially a 1 cm gap filled with cerebrospinal fluid (CSF) separates the brain from the rigid skull in adults and older children. Whole head acceleration induces a pulse of artificial gravity within the skull. Because brain density differs slightly from that of CSF, the brain accelerates and strikes the inner aspect of the skull, undergoing viscoelastic deformation, ranging from 1 …

Stray Threads: Factory Women In Fiction From The Freehold Farm To The Rented Room, 1840-1875, Meghan Wadle

English Theses and Dissertations

As industrialism unmoored agrarian-based American values surrounding independence, individualism, and the gender roles attached to labor, it demanded imaginative solutions for these potentially broken ideologies in antebellum fiction. This project, in two parts, explores how factory women stood at the center of the industrializing U.S.’s cultural identity crisis. In Part One authors from Herman Melville to Harriet Jacobs imagine women laboring in the industrial marketplace as a form of deviant dependency. Here, sexualized depictions of female laborers symptomatize national anxieties about how economic change might transform political freedom by simultaneously modifying traditional forms of patriarchal control. In Part Two, Lucy …

Tattoo For Life And Afterlife, Kimberly Chin

Capstones

Man has searched for ways to live forever from time immemorial. But a curious group of tattoo enthusiasts developed a way to preserve one’s tattoo skin (at the least) post-mortem. Here’s a cultural exploration of a small albeit growing trend in which people’s perception of tattoos, burial rites and how to commemorate loved ones is examined and re-examined.

Predicted Suitable Habitat Declines For Midwestern United States Amphibians Under Future Climate And Land-Use Change Scenarios, Brock Struecker, Joseph Milanovich

Biology: Faculty Publications and Other Works

With current declines of vertebrate taxa meeting or exceeding those of historic mass extinction events, there is a growing need to investigate the main drivers of losses. Two of the main drivers of declines are global climate and land-use changes, both affecting multiple groups of taxa. Amphibians are at great risk from these two drivers of change and investigations into the impact of future change could assist with the formation of conservation plans to mitigate losses. Forecasting changes in suitable habitat with ecological niche modeling serves as a useful tool to begin to understand how species may respond to anthropogenic …

Unseen Science: Modern Discoveries Too Far Away Or Tiny For Human Eyes, Lucy Huang

Capstones

As science has progressed, scientists have realized that evidence goes beyond the realms of physical sight. Whether it is too small or difficult to find, scientists have developed different ways to get around this problem. We see this in cancer genomics and in extrasolar planetary research. Scientists use what they know and what they measure to validate their work.

Of Rats And Men, Thomas S. Walsh

Capstones

This capstone is a data-driven investigation into New York City's rat problem. By using publicly available government data to map rat activity in NYC, I identified several socio-economic variables that correlate with rat populations at the community district, borough, and city-scale. I used these findings (mainly that rat problems are linked to lower incomes) as the basis of an investigation, which includes interviews with residents, experts, and city officials. Prof. Bobby Corrigan, urban rodentologist and formerly with the NYC Department of Health criticizes the city's efforts for the first time on the record.

Small-Animal Models Of Zika Virus, Justin G. Julander, Venkatraman Siddharthan

Animal, Dairy, and Veterinary Science Faculty Publications

Zika virus (ZIKV) infection can result in serious consequences, including severe congenital manifestations, persistent infection in the testes and neurologic sequelae. After a pandemic emergence, the virus has spread to much of the new world and has been introduced to many countries outside of endemic areas as infected travelers return to their home countries. Rodent models have been important in gaining a better understanding of the wide range of disease etiologies associated with ZIKV infection and for the initial phase of developing countermeasures to prevent or treat viral infections. We discuss herein the advantages and disadvantages of small animal models …

Getting Girls In Stem & The Dangers Of Forgetting That Science Is Art - Someone Made It Up, Heidi Therese Dangelmaier, Camilla Hermann

The Transdisciplinary STEAM+ Journal

Encouraging girls to participate in STEM is a hot topic that has captured the concern of the world’s academic, business and scientific communities. The intention is noble, however the strategies being deployed are reinforcing the very bias society seeks to eliminate. If we wish to advance our evolutionary journey as a species, a shift from “feeling sorry for disadvantaged girls” to “fearing STEM without girls’ reformation” is imperative. This piece discusses the rise to an initiative to redesign culture: Girlapproved.

Creativity, Laterality And Critical State Balance In Learning, Jenny Rock, Asher Flatt

The Transdisciplinary STEAM+ Journal

Understanding the intersecting cognitive pathways that are integral to ways of thinking, creating and functioning in both art and science is an important grounding for a STEAM educational approach. We combine three divergent concepts, including creativity, hemisphere laterality, and critical state theory, to argue for a more balanced approach to learning as part of a modern meaning-centered education in STEAM. Reviewing the concept of hemisphere laterality, or how the two hemispheres of our brain have different (though not disconnected) ways of processing sensory information, we note how these two means of interpreting the world have become unbalanced in traditional modes …
