Water Sustainability In The Nile, Rileigh Hanley

Discovery Day - Daytona Beach

The 2020 World Expo in 2022 is being held in Dubai, United Arab Emirates. There is a heavy focus on global innovations when it comes to environmental sustainability. As constant damage is done to the Nile, there is heavy threat towards environmental and human security. The question, “How does the pollution of the Nile effect its surrounding countries and what innovations at the World Expo can be used to mitigate the long and short-term effects?” will be explored during this Expo. To research different innovations and different perspectives towards the threat, I will be attending conferences at the Expo that …

"Man Of The Machine": Ernst Jünger's Philosophy Of Technology And The Spiritualization Of The ��������������������������������, Andrea L. Wisniewski

LSU Master's Theses

This thesis examines how conservative German war veterans, in particular author Ernst Jünger, granted meaning to the First World War by affirming the technological encounter. Instead of succumbing to the feelings of powerlessness and inferiority engendered by the domination of machinery on the Front, Jünger and other conservative veterans elevated the Materialschlacht into a spiritual event, a battle between the spirit and the material in which the human spirit emerged victorious. Strengthened by their confrontation with the machine, humans gained the spiritual skills which would enable them to master the machine and, therefore, meet the demands of the technological world. …

"Building Dialogue In Feminist Classrooms, Part 2: Student-Generated Discussion Points", Barbara Barrow, Sera Mathew

Feminist Pedagogy

In Part 2 of these linked Original Teaching Activities, we turn to dialogue and the use of student-generated discussion points to further build community in the feminist classroom. Once students have mastered a common vocabulary, we argue, this informal discussion points homework exercise offers rich opportunities for students to practice terms and concepts, engage in productive dialogue and active listening with their instructor and peers, interpret and analyze the course materials, and build problem-solving skills by navigating moments of conflict.

A Mixed-Methods Assessment Of Human Well-Being Related To The Presence Of Companion Animals During The Covid-19 Pandemic, Bindi Bennett, Suzie Cosh, Jack Thepsourinthone, Amy Lykins

People and Animals: The International Journal of Research and Practice

COVID-19 and the measures used to curb the pandemic (e.g., lockdowns, isolation) have significantly impacted mental health and well-being. This study sought to investigate the role of companion animals in alleviating stress and improving mental health during the pandemic. In this study, 250 Australian adults completed measures of well-being and life satisfaction, animal dependency, perceived emotional support from animals, and animals’ effect on mood. Employment and living with others were the strongest predictors of positive life satisfaction and well-being, while greater dependency on companion animals for emotional support and companion animals’ negative effects on mood were associated with reduced life …

Biochemical Characterization Of Induced Pluripotent Stem Cell-Derived Cardiomyocytes As A Model Of Barth Syndrome, Alisha J. House

ETD Archive

Barth Syndrome (BTHS) is an X-linked inborn error of metabolism (IEM) which manifests as a multi-systemic disease. One of the primary symptoms is dilated cardiomyopathy, and alongside the cardiovascular disease that arises, patients often experience metabolic abnormalities such as 3-methylglutaconic aciduria, growth retardation, and neutropenia. There has been a need for the development of a suitable in vitro modeling system which will accurately recapitulate the biochemical and physical nature of BTHS. The purpose of this project has been to develop a model for studying the biochemical pathogenesis of Barth Syndrome using human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs). To achieve …

Shifting Identities: Professorial Identification During Covid-19, Anthony Survance

Masters Theses & Specialist Projects

Building on existing studies of identification, this paper melds crisis research with studies of identity to understand how crises influence workplace identities. To accomplish this, the study addresses two research questions: (a) How are professors’ identities enacted during the COVID-19 crisis? And, how, if at all, does university rhetoric shape the enactment of identity during the COVID-19 crisis? This paper uses qualitative methods to get rich descriptions of professorial identities allowing research to get at the heart of how changes during the pandemic affected professors’ organizational, personal, professional, and workgroup identities. Overall, this study shows the pandemic encouraged professors to …

A Multi-Spatial Analysis Of Land Use Effects On Freshwater Mussels In The Upper Cuyahoga River And Tinkers Creek, Tamar Atwell

ETD Archive

Mussels are considered one indicator of good water quality in rivers, but over the past 20 years mussel populations have continued to decline, while water quality improves. According to the Ohio Environmental Protection Agency (OEPA), water quality in the Cuyahoga River is now within safe levels for all parameters. However, what are safe levels for humans may not be safe for mussels. An analysis of freshwater mussel populations in two similarly sized watersheds, the Upper Cuyahoga River and Tinkers Creek was conducted. Correlations of mussel abundance and diversity were assessed by multivariate GIS/remote sensing tools to contrast water flow rates, …

Self-Healing With Reiki For Homeless Individuals Suffering From Past Traumatic Events, Kathryn Piha

Theses and Graduate Projects

Living with symptoms that resemble PTSD from past trauma can be detrimental to health, healing, and quality of life. Symptoms that resemble PTSD are intrusive and disruptive to daily life and can cause anxiety, vivid flashbacks and nightmares, and intense memories. Homeless individuals navigate challenges and are at increased risk for developing symptoms that resemble PTSD. This project explored Reiki as a healing modality to improve health, healing, and quality of life from the negative implications of past traumatic experiences. Guided by Martha Roher's SUHB Theory, this project connects Reiki with energy as healing. Understanding energy and energy fields can …

The Role Of Affect And The Autonomic Nervous System (Ans) In Visuospatial Learning And Set-Shifting: Modulating Cardiac Vagal Tone Through Heart Rate Variability (Hrv) Biofeedback To Improve Cognitive Performance, Breannan C. Howell

Psychology ETDs

The fields of psychology and neuroscience have found an interconnection between the autonomic nervous system (ANS), affect, and cognitive performance. Heart rate variability (HRV) may be a useful index of this relationship, representing the regulatory processes that facilitate adapting to emotions and environments to modulate mood and executive function. The current project consists of a series of experiments to investigate the relationship between trait affect, HRV, learning, and set-shifting performance. In the first experiment associations are found between negative affectivity, HRV, and set-shifting performance during an attentional set-shifting variant of the Virtual Morris Water Task (VMWT). Participants that exhibited both …

Heart Rate Variability Following Treatment For Ptsd: Testing The Polyvagal Theory, Brittany F. Goodman

Dissertations

Posttraumatic stress disorder (PTSD) has been linked to lower heart rate variability (HRV), including measures of vagal tone. Treatments targeting the autonomic nervous system (ANS) have demonstrated efficacy in improving vagal tone, but it is less clear whether similar effects can also be achieved with cognitive therapies. The polyvagal theory has suggested that symptoms of social dysfunction are linked to vagal tone through a phylogenetically organized response to stress. HRV was collected during rest, reactivity (exposure to personalized trauma scripts), and recovery using a scripted imagery paradigm in female PTSD positive physical and sexual assault survivors (N = 41) …

Canonical Sentence Processing And The Inferior Frontal Cortex: Is There A Connection?, Nicholas Riccardi, Chris Rorden, Julius Fridriksson, Rutvik H. Desai

Faculty Publications

The role of left inferior frontal cortex (LIFC) in canonical sentence comprehension is controversial. Many studies have found involvement of LIFC in sentence production or complex sentence comprehension, but negative or mixed results are often found in comprehension of simple or canonical sentences. We used voxel-, region-, and connectivity-based lesion symptom mapping (VLSM, RLSM, CLSM) in left-hemisphere chronic stroke survivors to investigate canonical sentence comprehension while controlling for lexical-semantic, executive, and phonological processes. We investigated how damage and disrupted white matter connectivity of LIFC and two other language-related regions, the left anterior temporal lobe (LATL) and posterior temporal-inferior parietal area …

Acute Oxygen-Sensing Via Mitochondria-Generated Temperature Transients In Rat Carotid Body Type I Cells, Ryan J. Rakoczy, Clay M. Schiebrel, Christopher N. Wyatt

Neuroscience, Cell Biology & Physiology Faculty Publications

The Carotid Bodies (CB) are peripheral chemoreceptors that detect changes in arterial oxygenation and, via afferent inputs to the brainstem, correct the pattern of breathing to restore blood gas homeostasis. Herein, preliminary evidence is presented supporting a novel oxygen-sensing hypothesis which suggests CB Type I cell “hypoxic signaling” may in part be mediated by mitochondria-generated thermal transients in TASK-channel-containing microdomains. Distances were measured between antibody-labeled mitochondria and TASK-potassium channels in primary rat CB Type I cells. Sub-micron distance measurements (TASK-1: 0.33 ± 0.04 µm, n = 47 vs TASK-3: 0.32 ± 0.03 µm, n = …

Emerging Themes And Future Directions Of Multi-Sector Nexus Research And Implementation, Jennifer Schmidt

ISER Articles

Water, energy, and food are all essential components of human societies. Collectively, their respective resource systems are interconnected in what is called the “nexus”. There is growing consensus that a holistic understanding of the interdependencies and trade-offs between these sectors and other related systems is critical to solving many of the global challenges they present. While nexus research has grown exponentially since 2011, there is no unified, overarching approach, and the implementation of concepts remains hampered by the lack of clear case studies. Here, we present the results of a collaborative thought exercise involving 75 scientists and summarize them into …

Data-Driven Learning How Oncogenic Gene Expression Locally Alters Heterocellular Networks, David Klinke Ii, Audry Fernandez, Wentao Deng, Atefeh Razazan, Habibolla Latifizadeh, Anika C. Pirkey

Faculty & Staff Scholarship

Developing drugs increasingly relies on mechanistic modeling and simulation. Models that capture causal relations among genetic drivers of oncogenesis, functional plasticity, and host immunity complement wet experiments. Unfortunately, formulating such mechanistic cell-level models currently relies on hand curation, which can bias how data is interpreted or the priority of drug targets. In modeling molecular-level networks, rules and algorithms are employed to limit a priori biases in formulating mechanistic models. Here we combine digital cytometry with Bayesian network inference to generate causal models of cell-level networks linking an increase in gene expression associated with oncogenesis with alterations in stromal and immune …

Something Fishy In Seafood Trade?, Kathy Baylis, Lia Nogueira, Linlin Fan, Kathryn Pace

Cornhusker Economics

The safety of food imports continues to be in the spotlight. Globally, each year, contaminated food causes almost 1 in 10 people to fall ill and 420 thousand people to die (WHO, 2017). Protecting consumers from unsafe foods is complicated by the increased role of international trade in our food system. The U.S. Centers for Disease Control and Prevention found that disease outbreaks associated with imported food increased from 1996 to 2014, with fish and produce being the main culprits (Gould et al., 2017). For example, in 2019, two separate cases of tuna from Vietnam were found to have sickened …

Neuronal Origins Of Reduced Accuracy And Biases In Economic Choices Under Sequential Offers, Weikang Shi, Sebastien Ballesta, Camillo Padoa-Schioppa

2020-Current year OA Pubs

Economic choices are characterized by a variety of biases. Understanding their origins is a long-term goal for neuroeconomics, but progress on this front has been limited. Here, we examined choice biases observed when two goods are offered sequentially. In the experiments, rhesus monkeys chose between different juices offered simultaneously or in sequence. Choices under sequential offers were less accurate (higher variability). They were also biased in favor of the second offer (order bias) and in favor of the preferred juice (preference bias). Analysis of neuronal activity recorded in the orbitofrontal cortex revealed that these phenomena emerged at different computational stages. …

Rapid Range Expansion Of A Marine Ectotherm Reveals The Demographic And Ecological Consequences Of Short-Term Variability In Seawater Temperature And Dissolved Oxygen, Benjamin P. Buford, Lauren A. Wild, Richard Schwarz, Ellen M. Chenoweth, Ashwin Sreenivasan, Robin Elahi, Nicholas Carey, Henk-Jan T. Hoving, Janice Straley, Mark W. Denny

Faculty

The distributions of marine ectotherms are governed by physiological sensitivities to long-term trends in seawater temperature and dissolved oxygen. Short-term variability in these parameters has the potential to facilitate rapid range expansions, and the resulting ecological and socioeconomic consequences may portend those of future marine communities. Here, we combine physiological experiments with ecological and demographic surveys to assess the causes and consequences of sudden but temporary poleward range expansions of a marine ectotherm with considerable life history plasticity (California market squid, Doryteuthis opalescens). We show that sequential factors related to resource accessibility in the core range—the buildup of large populations …

Simple But Not Easy: An Examination Of The Test-Retest Reliability Of The Perceived Stress Scale (Pss-10) And Exploration Of A Meditation App For Stress Management With High School Students, Eileen Kaskons

Counseling and Psychology Dissertations

Stress can have a negative effect on overall well-being, trigger physical disease, and contribute to mental health disorders. The 10-item Perceived Stress Scale (PSS-10) is frequently used in research. However, there are limited studies on the test-retest reliability of the PSS-10 with adults, and no studies could be identified that tested this issue with adolescents. Meditation apps are often recommended for stress reduction, but they have not been widely studied for use in high school. This study investigated the test-retest reliability of the PSS-10 and examined the feasibility of using a meditation app with high school students. First, a comprehensive …

Mtdna Heteroplasmy Gives Rise To A New Maternal Lineage In North Pacific Humpback Whales, Sophie P. Pierszalowski, Debbie J. Steel, Christine M. Gabriele, Janet L. Neilson, Phoebe B. Vanselow, Jennifer A. Cedarleaf, Janice M. Straley, C. Scott Baker

Faculty, Staff, and Students

Heteroplasmy in the mitochondrial genome offers a rare opportunity to track the evolution of a newly arising maternal lineage in populations of non-model species. Here, we identified a previously unreported mitochondrial DNA haplotype while assembling an integrated database of DNA profiles and photo-identification records from humpback whales in southeastern Alaska (SEAK). The haplotype, referred to as A8, was shared by only two individuals, a mature female with her female calf, and differed by only a single base pair from a common haplotype in the North Pacific, referred to as A-. To investigate the origins of the A8 haplotype, we reviewed …

Effects Of Spatially Heterogeneous Lakeside Development On Nearshore Biotic Communities In A Large, Deep, Oligotrophic Lake, Michael F. Meyer, Ted Ozersky, Kara H. Woo, Kirill Shchapov, Aaron W. Galloway, Julie B. Schram, Emma J. Rosi, Daniel D. Snow, Maxim A. Timofeyev, Dmitry Yu. Karnaukhov, Matthew R. Brousil, Stephanie E. Hampton

Sewage released from lakeside development can reshape ecological communities. Nearshore periphyton can rapidly assimilate sewage-associated nutrients, leading to increases of filamentous algal abundance, thus altering both food abundance and quality for grazers. In Lake Baikal, a large, ultra-oligotrophic, remote lake in Siberia, filamentous algal abundance has increased near lakeside developments, and localized sewage input is the suspected cause. These shifts are of particular interest in Lake Baikal, where endemic littoral biodiversity is high, lakeside settlements are mostly small, tourism is relatively high ( 1.2 million visitors annually), and settlements are separated by large tracts of undisturbed shoreline, enabling investigation of …

Living Between The Lines: How Japanese Crafts Taught Frank Lloyd Wright, Adolf Loos, And Eileen Gray To See Modern Domestic Space, Regina Nabil Emmer

Art & Art History ETDs

Histories of European and U.S. modernism conventionally accept that Enlightenment rational thought set modern architecture’s terms and criteria in the late-nineteenth and early-twentieth centuries. Rationalism privileges visual and material properties; distinguishes between art, architecture, and craft; and identifies space with the structure that frames it. It normalized the view that buildings stand fixed, independent of our interaction with them, and perpetuates assumptions about what physically defines domestic space. Consequently, Japan’s significance for modern domestic space in Europe and the U.S. has been interpreted as structurally evident. Simultaneously, the architecture of European and U.S. modernists who did not think like rationalists …
