The Effect Of Step Rate Training On Running Economy And Biomechanics, Nahir Negron-Fernandez
The Effect Of Step Rate Training On Running Economy And Biomechanics, Nahir Negron-Fernandez
All NMU Master's Theses
It is known that running economy is a determinant of running performance. Increased step rate has been correlated with improved running economy, but it is unknown whether these improvements can be maintained with chronic training. The purpose of this study was to determine if a step rate training intervention improves running economy and improves lower body kinetic factors in distance runners. Nine participants were randomly assigned to either an intervention group (n = 7) undergoing a 6-week supplemental training program, or a non-training control group (n = 2). The intervention group trained three times a week, running at a higher …
The Impacts Of Embryo Development And Asynchronous Hatching On Morphology, Growth, And Development Of Larval Burbot (Lota Lota)., Andrew J. Shapiro
The Impacts Of Embryo Development And Asynchronous Hatching On Morphology, Growth, And Development Of Larval Burbot (Lota Lota)., Andrew J. Shapiro
All NMU Master's Theses
Burbot (Lota lota) are native fish in Lake Superior and typically spawn during the winter under the ice or by migrating up rivers. The early life history of larval burbot, where they dispurse, how fast they develop, and what their survival rates have not been extensively studied. Asynchronous hatching is a strategy used by other cod species as a bet-hedging strategy to ensure that some larvae are hatched in more advantageous conditions in a varying environment. Asynchronous hatching has been documented in burbot, but the extent of the period and the impacts that asynchrony has on the development of …
Attention Bias To Climate Change Images Following Emotional Inducements Of Pride And Guilt, Caleb W. Coughtry-Carpenter
Attention Bias To Climate Change Images Following Emotional Inducements Of Pride And Guilt, Caleb W. Coughtry-Carpenter
All NMU Master's Theses
Climate change is the most important issue facing modern day humans, and the solutions are not developing at a quick enough rate. In many cases, human-derived climate effects have crossed the threshold to becoming irreversible, and, as we remain inactive, are continuing to worsen as mitigating steps are not taken. Some of the most devastating effects facing humans include rising sea levels that threaten to flood coastal regions, and heatwaves of heightened intensity which threaten access to potable water and loss of food crops. Humans are not the only victims of climate change. Ecosystems are also greatly threatened by climate …
Correlation Between Scores On The Assessment And Learning In Knowledge Spaces Placement, Preparation, And Learning Test And General Chemistry Course Outcomes For Undergraduate Students At A Public Midsize Master's University, Crystal Kaye Keso
All NMU Master's Theses
This study examined the problem of gateway courses in Science, Technology, Engineering, and Mathematics (STEM), specifically, high-enrollment introductory chemistry courses with high rates of D, F, withdrawal, or incomplete grades. Previous research revealed a correlation between students’ prior mathematics knowledge and introductory chemistry course outcomes. Reports using the Assessment and Learning in Knowledge Spaces Placement, Preparation, and Learning (ALEKS PPL) test were limited in number. This study conducted a non-experimental retrospective correlational analysis between undergraduate students’ ALEKS PPL test scores and introductory chemistry course grades. The study’s theoretical framework was grounded in prerequisite and placement testing theories. The major findings …
Resting-State Functional Connectivity Correlates Of Attentional Bias In An Emotional Free Viewing Paradigm: An Eye-Tracking Investigation, Andrew Hauler
All NMU Master's Theses
Threat detection, the process of searching complex environments for harmful stimuli, represents a vastly important job that promotes the biological fitness of the organism. Decades of experimental evidence suggests individuals either diagnosed, or at risk for, affective disorders display altered patterns of attentional engagement (hypervigilance or maintenance) with external stimuli; referred to as attentional biases. To date, the extent to which underlying neural mechanisms drive attentional biases, both in affective disorders as well as unselected populations, remain to be resolved. Thus, using eye-tracking and a passive emotional free viewing task, this study set to clarify resting-state network contributions from three …
Effects Of Static Versus Dynamic Cupping On Ankle Dorsiflexion, Alexandria N. Schaub
Effects Of Static Versus Dynamic Cupping On Ankle Dorsiflexion, Alexandria N. Schaub
All NMU Master's Theses
PURPOSE: Cupping therapy involves lifting and separating fascial tissue to facilitate stretching and promote blood flow. Although cupping is a common treatment modality for pain, studies are inconsistent in regards to whether cupping improves other outcomes, like range of motion. Possessing a limited range of motion can lead to musculoskeletal injury. The aim of this research is to determine the acute effect of different methods of cupping therapy on ankle dorsiflexion. METHODS: A total of 35 healthy adults (age: 22.1±4.52 years) with an average ankle ROM of 34.68±4.22° at baseline were included in the study. Participants were randomly …
Control Of Pausing In Rich-Lean Transitions By Spatially Localized And Spatially Diffuse Stimuli, Carson S. Yahrmarkt
Control Of Pausing In Rich-Lean Transitions By Spatially Localized And Spatially Diffuse Stimuli, Carson S. Yahrmarkt
All NMU Master's Theses
Signaled transitions from rich (favorable) to lean (less favorable) schedules of reinforcement (i.e., rich-lean transitions) can disrupt operant behavior. Previous literature suggests that disruptions in these transitions could occur because individuals engage in other behavior that reduces contact with the schedule-correlated stimuli. My thesis project evaluated this possibility by using different stimuli to manipulate the ease by which rats could reduce contact with schedule-correlated stimuli during signaled rich-lean transitions. We arranged a two-component multiple fixed ratio-fixed ratio (FR-FR) schedule to evaluate effects of different types of schedule-correlated stimuli on pausing in rich-lean transitions using rat subjects. Components had equivalent FR …
The Effects Of Dormant Season Burning And Flooding On Invasive Cattail, Typha X Glauca, On Rainy Lake And Lake Kabetogama In Northern Minnesota, Erika Meints
All NMU Master's Theses
Typha x glauca is one of the most invasive plants in North America. The plant exhibits hybrid vigor and displaces native flora by rapidly forming dense monotypic stands that can break free from the substrate and form floating mat types when established. I tested the effects of prescribed burning, on Typha x glauca in wetlands to adjacent large lakes in Voyageurs National Park in northern Minnesota. My team surveyed four wetlands that were burned in late winter of 2020-21, and six that were unburned controls. Pre-burn data was also collected for all ten wetlands. Pre-flooding data from other wetlands within …
Appropriated Voices: William Blake’S “The Little Black Boy” And British Antislavery Poetry, Brett J. Mattson
Appropriated Voices: William Blake’S “The Little Black Boy” And British Antislavery Poetry, Brett J. Mattson
All NMU Master's Theses
British antislavery poetry in the late 1700s is well characterized by the first stanza of William Blake’s poem “The Little Black Boy” when his black speaker says “o! my soul is white; … But I am black as if bereav’d of light” (2-4). These statements that seem to exclude each other exemplify the discussions and arguments that antislavery poets had been publishing and would continue to deliberate after “The Little Black Boy” was printed in 1789. Other poets, while appropriating the voices of enslaved people or Africans, as Blake does in “The Little Black Boy,” often emphasize differences between their …
Sympatric Soil Microbe Interactions Between Streptomyces And Fusarium Isolates, Lehren A. Olk-Szost
Sympatric Soil Microbe Interactions Between Streptomyces And Fusarium Isolates, Lehren A. Olk-Szost
All NMU Master's Theses
Interkingdom interactions between soil bacteria and fungi may play a critical role in occurrence of disease suppressive soils, yet our understanding of these interactions remains limited. Streptomyces are well-known producers of antimicrobial compounds important to medicine and agriculture. Production of these secondary metabolites is often mediated by quorum sensing. Most Streptomyces research occurs in single species experiments, yet new metabolites have been discovered in interspecies co-culture experiments. Interspecies, intergenic, and interkingdom co-culture research will likely reveal many valuable compounds, and strengthen our understanding of complex ecological interactions in soil microbiomes. Interactions between sympatric Streptomyces and Fusarium isolates from disease suppressive …
Trophic Dynamics Of The Lake Superior Fish Community, Ariel Edwards
Trophic Dynamics Of The Lake Superior Fish Community, Ariel Edwards
All NMU Master's Theses
The Lake Superior food web has undergone many changes in recent decades, including the rehabilitation of the native apex predator lake charr (Salvelinus namaycush) and the introduction of several nonnative species. The trophic linkages and ecological requirements of the entire fish community, including predators and prey fishes, has not been assessed on a whole-lake scale in over a decade. Here, I investigated the trophic dynamics across multiple regions of the lake, and estimated the consumptive effect of lean lake charr in one region of Lake Superior. From April to October of 2021, a total of five predator, four …
Transactional And Transformational Leadership In The Superintendency: A Phenomenological Study Of Three Upper Peninsula Superintendents’ Experiences, Lisa A. Coombs-Gerou
Transactional And Transformational Leadership In The Superintendency: A Phenomenological Study Of Three Upper Peninsula Superintendents’ Experiences, Lisa A. Coombs-Gerou
All NMU Master's Theses
This study aimed to analyze and provide an understanding of how three rural public school superintendents in the Upper Peninsula of Michigan practiced transformational leadership. Transformational leadership includes the elements of idealized influence, inspirational motivation, intellectual stimulation, and individual consideration (Burns, 1978). Transformational superintendents must lead our schools to provide students with the best educational opportunity. The study focused on the superintendents experiences in deciding to become a superintendent, their beliefs about leadership, and how they approached decisions through a transactional or transformational process. The study also sought to provide insight into the relationship with their school board and how …
Sue, Heath Joseph Wooten
Sue, Heath Joseph Wooten
All NMU Master's Theses
Sue is a collection of poetry investigating the cyclical nature of grief through the lens of Eve Kosofsky Sedgwick’s schemas of paranoid and reparative readings. The poems employ motifs such as hunting, disease, and human remains to capture the temporal disorientation experienced in the wake of loss. Via an extensive use of metaphor and recurring poem titles, Sue exploits the multivalence of language to conjure a dense field of meaning, meant to capture the undecidability of language noted by philosopher Jacques Derrida. This collection also employs several vectors of derivation, including erasure of text lifted from the 2002 strategy video …
Science, Community, And Culture: A Holistic Approach To Ecological Research And Education, Laura Whipple
Science, Community, And Culture: A Holistic Approach To Ecological Research And Education, Laura Whipple
All NMU Master's Theses
Global biodiversity has declined at an alarming rate over the past century as a result of many complex human-induced environmental changes. Standardized surveys have historically been used to identify drivers of species declines, but such studies are often resource-intensive, resulting in significant spatial and temporal data gaps when researchers lack the resources necessary to maintain such studies. One promising solution for overcoming gaps in standardized studies is the integration of species observations by community members (e.g., community science). Along with improving modeling techniques to address biodiversity declines, the education of future ecologists on the importance of Indigenous ecological knowledge, robust …
Transcutaneous Electrical Stimulation Does Not Decrease Torque Loss Over High Intensity Repetitions, Ian Koskinen
Transcutaneous Electrical Stimulation Does Not Decrease Torque Loss Over High Intensity Repetitions, Ian Koskinen
All NMU Master's Theses
Transcutaneous Electrical Stimulation, TENS, has been used widely as an analgesic and ergogenic aid for many years. Compared to other modalities of electrical stimulation, TENS has been shown to provide some benefits in exercise performance by reducing pain and increasing endurance in low intensity applications, such as time trial cycling or isometric endurance. While TENS has been shown to have a significant effect on exercise induced pain in individuals performing endurance activities, to my knowledge it has not been examined in high intensity contractions. 18 active young adults (age: 23.11 years ± 2.08, resistance training experience: 7.08 years ± 3.79, …
Fecal Cortisol Metabolites: A Non-Invasive Method For Monitoring The Long-Term Health Of Free Ranging Brown Bears, Justin A. Pinero
Fecal Cortisol Metabolites: A Non-Invasive Method For Monitoring The Long-Term Health Of Free Ranging Brown Bears, Justin A. Pinero
All NMU Master's Theses
Ecotourism is a rapidly growing industry worldwide and has been used as a tool that can promote conservation. While ecotourism can serve as a mechanism to help conserve natural areas, increases in visitors present challenges for managers tasked with balancing conservation goals while ensuring positive visitor experiences. As such, managers and ecologists are increasingly using fecal cortisol metabolites (FCMs) to index stress associated with ecotourism. In this study, I sought to (1) quantify the relationship between blood cortisol levels and FCM concentrations in brown bears (Ursus arctos), and (2) evaluate whether ecotourism elicits a measurable stress response in …
Effect Of Covid-Protocols On Athletic Training Burnout, Harrison C. Garcia
Effect Of Covid-Protocols On Athletic Training Burnout, Harrison C. Garcia
All NMU Master's Theses
Burnout is a psychological condition consisting of emotional exhaustion, depersonalization, and a decreased sense of personal accomplishment and identity. Since the start of the pandemic, a significant increase in burnout has been reported by healthcare professionals, however, there is little known regarding the experiences of athletic trainers (ATs). PURPOSE: The purpose of our study was to investigate the association between burnout and COVID-19 related factors among ATs. METHODS: An electronic survey grouped by the Maslach Burnout Inventory – Human Services Survey, COVID-19 related workplace policies, and demographics was sent to 1,000 ATs through the National Athletic Trainer’s Association email listserv; …
The Possible Role For Basigin Receptor Function In The Induction Of Matrix Metalloproteinase Expression In Human Endometrial Stromal Cells, Amy Abel
All NMU Master's Theses
10-15% of couples worldwide are affected by infertility. The leading cause of infertility is implantation failure. Molecular communication in precise time and space between an implanting embryo and a receptive uterus is essential for successful implantation. Basigin has been shown to have vital functions within the implantation process. Basigin is best known for inducing the expression of matrix metalloproteinases. Basigin has been shown to induce MMP expression in vitro in human endometrial stromal cell lines (HESC). Understanding how basigin induces matrix metalloproteinases within normal cellular conditions will help researchers understand how these signaling cascades flow in the framework of implantation. …
The Status Of Invasive Dusky Slug (Arion) Species In The Upper Great Lakes: A Molecular Approach, Olivia W. Hall
The Status Of Invasive Dusky Slug (Arion) Species In The Upper Great Lakes: A Molecular Approach, Olivia W. Hall
All NMU Master's Theses
I update the distribution of two cryptic slug species, Arion fuscus and Arion subfuscus, in the Upper Great Lakes of the United States using molecular identification methods. Arion fuscus has not previously been reported in the literature in this region, and Arion subfuscus has previously been reported as abundant. However, all previous distribution studies were determined using visual identification tools, which can result in misidentification between cryptic species. To molecularly re-examine these distribution maps, I used a mitochondrial ribosomal subunit 16S PCR amplification and subsequent SSpI and MfeI restriction enzyme digest to identify slug specimens. I collected slugs in …
