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, …

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) …

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 …

Flight Plan For The Future: Floatplane Pilots And Researchers Team Up To Predict Invasive Species Dispersal In Alaska, Jennifer Schmidt

ISER Articles

Aircraft can transport aquatic invasive species (AIS) from urban sources to remote waterbodies, yet little is known about this long-distance pathway. In North America and especially Alaska, aircraft with landing gear for water called floatplanes are used for recreation access to remote, often road-less wilderness destinations. Human-mediated dispersal of AIS is particularly concerning for the conservation of pristine wildlands, yet resource managers are often challenged by limited monitoring and response capacity given the vast areas they manage. We collected pathway data through a survey with floatplane pilots and used a Bayesian hierarchical model to inform early detection in a data-limited …

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 …

Integrated Nonmarital Property Rights, E. Gary Spitko

Faculty Publications

Nonmarital cohabitation has become a mainstream family structure in the United States. Yet, despite the increasing prevalence of nonmarital cohabitants, American family property law generally fails to support nonmarital couples. This inequality under the law disproportionately disadvantages persons of color, those with relatively less education, and couples with relatively fewer economic resources. This Article considers the post-Obergefell need for law reform to better support nonmarital families, examines the principles that should ground nonmarital property rights reform, and proposes a novel approach to nonmarital property rights that integrates the law of dissolution with the law of succession, unifies the law governing …

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

Faculty, Staff, and Students

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 …

Naps: A New Approach To Decrease Patient Adverse Outcomes, Ayesha Lakhani

MSN Capstone Projects

Hospitals have been short staffed, especially during the pandemic. Due to this many staff members have been overworked causing them to become stressed, exhausted, and not alert which is resulting in adverse patient outcomes (Aiken et al., 2004). One of the solutions suggested so far is nap. Nap is a low-cost solution which can help reduce the adverse outcomes of working and help promote positive patient outcomes. This benchmark study is a guide to institute naps and will provide a detailed step-by-step instruction to anyone to ensure a successful implementation of the project.

Telemedicine For Rheumatology Patients In Covid-19 Pandemic: Perspectives Of Patients, Muhammad Mehmood Riaz, Saad Bin Zafar Mahmood, Noreen Nasir

Section of Internal Medicine

Telemedicine use for patients with autoimmune rheumatic conditions during the pandemic mandates better characterization. We conducted a telephonic survey on patients who consulted rheumatologists remotely to determine their attitudes toward telemedicine. The study was conducted at Aga Khan University Hospital, a tertiary care hospital in Pakistan which is a lower-middle-income country. Descriptive analyses were performed. Fifty patients visited tele-rheumatology clinic, 35 (70.0%) were female with a mean (SD) age of 47.6 (18.1) years. Majority (27, 54.0%) learned about telemedicine from hospital website and outpatient clinic desk or helpline. Lack of examination was the biggest concern with teleconsultation (18, 22.2%). Most …

Naltrexone Alters Cardiovascular Function Following Acute Forced Swimming In Mice, Candace R. Longoria, Quadratullah Qadiri, Evan L. Matthews, Sara C. Campbell, John J. Guers

Department of Exercise Science and Physical Education Scholarship and Creative Works

Purpose Naltrexone (NTX) is an opioid antagonist that can reverse the physiological effects of opioid receptors when bound. Opioid receptors have been found to play a role in cardiovascular (CV) function, and thus, binding of NTX may alter CV activity at rest and in response to acute and chronic exercise (EX). We hypothesized that opioid receptor blockade will alter the typical CV responses following acute EX. Methods We assessed the effects of opioid receptor blockade on CV function via echocardiography in mice following an acute bout of forced swimming (FSw), a model of rodent EX. We administered opioid receptor antagonist, …

Valuation Of Dry And Wet Aged Beef By U.S. Consumers, Mario Ortez, Nicole Olynk Widmar, Nathan M. Thompson, Yuan H. Brad Kim

Department of Agricultural Economics Faculty Publications

Aged-beef has historically been available in high-end establishments, but investigation into consumer preferences for aging is increasingly important as it has become more readily available. Consumer perceptions of and willingness-to-pay (WTP) for aged-beef under two methods dry-aging and wet-aging, were studied in a representative sample of n = 1,275 US residents alongside USDA quality grades. In general, US residents are not knowledgeable regarding aged-beef but have a positive direct-stated perception of the practice. Respondents self-reported familiarity with USDA grades Prime and Choice and perceived them as superior beef attributes. Half of respondents were randomly assigned to receive a low information …

Role Of Extracellular Vesicles In Glia-Neuron Intercellular Communication, Shahzad Ahmad, Rohit K Srivastava, Pratibha Singh, Ulhas P. Naik, Amit K Srivastava

Department of Medicine Faculty Papers

Cross talk between glia and neurons is crucial for a variety of biological functions, ranging from nervous system development, axonal conduction, synaptic transmission, neural circuit maturation, to homeostasis maintenance. Extracellular vesicles (EVs), which were initially described as cellular debris and were devoid of biological function, are now recognized as key components in cell-cell communication and play a critical role in glia-neuron communication. EVs transport the proteins, lipids, and nucleic acid cargo in intercellular communication, which alters target cells structurally and functionally. A better understanding of the roles of EVs in glia-neuron communication, both in physiological and pathological conditions, can aid …

An Investigation Into The Protein Dynamics And Proton Transfer Mechanism Of Class-A Β-Lactamase (Ctx-Ms) By Nmr Spectroscopy, Radwan Ebna Noor

USF Tampa Graduate Theses and Dissertations

Extended-spectrum β-lactamases (ESBLs) of different Enterobacteriaceae (e.g. Escherichia coli, Klebsiella pneumoniae) have developed significant resistance mechanisms against antibiotics. ESBLs, like class A CTX-Ms (cefotaximases) enzymes hydrolyze the β-lactam ring of different antibiotics such as penicillins and third-generation oxyimino-cephalosporins. Although CTX-Ms are repeatedly found in many clinical and community settings, molecular-level information on their function/activity is currently limited to structural studies performed by X-ray crystallography. In order to gain further insights into the structure and functions of this class of proteins, it is also essential to fully understand their dynamic and chemical properties in solution. In order to better understand the …

Soil Depth And Precipitation Moderate Soil Textural Effects On Seedling Survival Of A Foundation Shrub Species, Kari E. Veblen, Kyle C. Nehring, Michael C. Duniway, Anna Knight, Thomas A. Monaco, Eugene W. Schupp, Janis L. Boettinger, Juan J. Villalba, Stephen Fick, Colby Brungard, Eric Thacker

Wildland Resources Faculty Publications

In drylands, there is a need for controlled experiments over multiple planting years to examine how woody seedlings respond to soil texture and the potentially interactive effects of soil depth and precipitation. Understanding how multiple environmental factors interactively influence plant establishment is critical to restoration ecology and in this case to broadscale restoration efforts in western U.S. drylands dominated by big sagebrush (Artemisia tridentata). We planted sagebrush seedlings across a range of soil textures and depths in the southern portion of the species' range, on the Colorado Plateau, USA. We evaluated survival of repeated plantings of caged and …
