Fish Sound Production: The Swim Bladder, Michael L. Fine, Eric Parmentier

Biology Publications

Analogous to the syrinx in birds and larynx in mammals, the swim bladder is a major sound-producing organ in fishes. It also functions in hearing and is responsible for most returns from sonar. Historically, the swim bladder has been modeled as an underwater resonant bubble, whereas we provide evidence for a forced-response model in which viscous damping of the bladder wall inhibits resonance of the internal bubble. Further experimental work on the shape, wall structure, and mechanical behavior of the swim bladder is required.

An Investigation Of Bubble Resonance And Its Implications For Sound Production By Deepwater Fishes, Mark W. Sprague, Michael L. Fine, Timothy M. Cameron

Biology Publications

Although the continental slope and abyss comprise the largest habitat on earth, the absence of documented fish sounds from deep waters is striking. Fishes with sexually dimorphic muscles attached to their swim bladders suggests that sounds are likely used in male courtship on the upper, mid and lower continental slope. To investigate the effects of environmental extremes on fish sound production, the acoustic behavior of a driven bubble is examined. This study is also relevant to target strength of sonar returns from fish and hearing in auditory specialist fishes. A bubble is a classic, if imperfect, model for swim bladder …

Absent Fathers And Child Maintenance Rights In The Copperbelt Province Of Zambia: The Dilemma Of A Postcolonial Bemba Matrilineal Practice, Mutale Mulenga-Kaunda

Zambia Social Science Journal

Being matrilineal and matrilocal, the Bemba people believe that “children belong to the mother”. This cultural belief and practice is so resilient that even in the event of divorce men have lost paternity rights to their children. Colonisation shifted Bemba women’s status as men were forced to migrate to work in the mines on the Copperbelt, leaving women to raise children as single mothers often without support from their absent husbands. Yet, even though Bemba people believe that children belong to the mother, the responsibility of raising children was traditionally shared with the father of the child. In postcolonial Zambia, …

Vision And Radar Steering Reduces Agricultural Sprayer Operator Stress Without Compromising Steering Performance, Travis A. Burgers, Kelly J. Vanderwerff

Mechanical Engineering Faculty Publications

Self-propelled agricultural sprayer operators work an average of 15 h d^-1 in peak season, and steering is the task that causes the operator the most stress because of the large number of stimuli involved. Automatic guidance systems help reduce stress and fatigue for operators by allowing them to focus on tasks other than steering. Physiological signals like skin conductance (electrodermal activity, EDA) change with stress and can be used to identify stressful events. The objective of this study was to determine if using a commercially available vision and radar guidance system (VSN®, Raven Industries) reduces agricultural sprayer operators’ stress …

Code-Switching And Advising In Multilingual African Situations: An Analysis Of Radio Phone-In Programmes In Kenya And Cameroon, Billian Khalayi Otundo, Susanne Mühleisen

Journal of the Language Association of Eastern Africa

Radio phone-in programmes are relevant for linguistic analysis in multilingual contexts, like Kenya and Cameroon, because they provide relatively natural data in expert-user and user-user contexts in an often emotional interactive environment. Any topic on relationships is an emotive undertaking in any society given the varied cultural disparities. In radio phone-in programmes, speech activities such as advice-giving and advice-receiving are also performed symmetrically or asymmetrically. In this media format, code-switching is a highly important phenomenon that is an expected and unconscious part of the linguistic behaviour of multilingual speakers. Switches between languages are highly relevant since they provide evidence for …

Hispanic-Serving Institutions As Racialized Organizations: Elevating Intersectional Consciousness To Reframe The “H” In Hsis, Blanca Elizabeth Vega, Román Liera, Mildred Boveda

Department of Educational Leadership Scholarship and Creative Works

Conceptualizations of servingness must include an understanding of how racial ideologies shape Hispanic-Serving Institutions (HSIs). Three Latinx scholars offer testimonios on our experiences as students, faculty, and researchers at teaching and research-intensive HSIs. From our testimonios, we found that practices of Blanqueamiento (Whitening of a population) and Mestizaje (racial mixture) operate at HSIs to flatten our understanding of Hispanics in U.S. society. To make sense of our testimonios within these HSI contexts and constraints, we applied an intersectional consciousness perspective on racialized organizations. Findings include Whiteness operating as a credential, legitimizing unequal resources, diminishing agency among minoritized groups, and continued …

Effects Of Dissociation And Hyperarousal On Item And Association Memory, Naomi M. Wright

Electronic Theses and Dissertations

Dual representation theory (DRT) asserts that when an individual experiences an acutely stressful or traumatic event, encoding of memory of individual parts of an event (i.e., items) is enhanced, while connections between parts of an event (i.e., associations) is impaired due to peritraumatic changes in cognitive functioning. The current project sought to refine understanding of DRT by examining the differential effect of dissociation and hyperarousal, two common peritraumatic cognitive reactions, on memory for item and association information. Method: Using experimental methods from the cognitive study of memory, two studies evaluated how individual differences in cognitive states (Study 1) and experimentally …

Exploring The Intersections Of Stigma And Masculinity In The Illness Perceptions Of Men Living With Fibromyalgia: An Interpretative Phenomenological Analysis, Christine L. Motzny

Electronic Theses and Dissertations

Fibromyalgia is a musculoskeletal condition characterized by widespread pain, fatigue and cognitive problems. While it affects between 2-7% percent of the population in the United States, the biopsychosocial impacts of the disease on the lives of those affected are so substantial that it is considered to have one of the highest cost burdens comparative to other chronic pain conditions. Fibromyalgia has historically been deemed a contested illness due to the complexity of its presentation and lack of clear etiology. As a result, people with fibromyalgia often feel misunderstood and stigmatized. Like other pain conditions, fibromyalgia is more commonly diagnosed in …

Exploring Gaps In Understanding And Responding To Ageism: A Conceptual Model, Psychosocial Health, And Racialized Ageism, Andrew T. Steward

Electronic Theses and Dissertations

Ageism is an insidious, prevalent social justice issue which has harmful effects on the health of older adults. This dissertation includes three manuscripts which explore gaps in understanding and responding to ageism through three distinct methodological approaches. Two primary gaps are addressed in the three manuscripts: 1) conceptualizing and testing activities or interventions to reduce internalized ageism and enhance psychosocial health for older adults, and 2) exploring the intersectionality of ageism with racism.

The first manuscript draws from stereotype embodiment theory and theories of successful and productive aging to detail a conceptual model of interventions which may reduce internalized ageism …

Are You My Nurse? The Effects Of Patient-Delivered Gender Microaggressions On Women Trainees’ Clinical Work In Integrated Primary Care, Julia Ratchford Kauffmann

Electronic Theses and Dissertations

Gender microaggressions are a form of sexist discrimination that have detrimental effects on women’s psychological well-being. Unfortunately, these sexist occurrences are commonplace in the United States and can be experienced in a variety of ways. As such, there is a need to understand behavioral health providers’ experiences with patient-delivered gender microaggressions. In doing so, we may be able to better support women behavioral health trainees’ during their clinical development by potentially understanding the ways in which women trainees are affected by sexist patient encounters. Therefore, the present study sought to apply the Social Cognitive Model of Counselor Training and the …

Inhibitors Of Alpha-Synuclein Aggregation, Jemil Ahmed

Electronic Theses and Dissertations

Alpha-Synuclein (αS) – a neuronal, disordered, presynaptic protein – aggregates into amyloid fibrils and accumulates in the substantia nigra pars compacta of Parkinson's Disease (PD) patients. The aggregation and accumulation of αS amyloid fibrils leads to death of dopaminergic neurons; a hallmark of PD. Although it’s not clear why αS aggregates, prior studies have found that intrastriatal injection of fibril alone is sufficient to cause PD pathology in mouse and non-human primates models. These observations implicate αS as a therapeutic target against PD.

Unfortunately, there are three caveats when attempting to target αS. First, αS is a neuronal protein expressed …

The Role Of Ehd2 In Endothelial Cells, Rachael Judson

Electronic Theses and Dissertations

The role of EHD2 in terms of Cav1 interaction had not been previously characterized and was the main goal of this research. Cav1 has been shown to lead to the ubiquitination of Rac1. Because of this, the role of EHD2 in Rac1 regulation was investigated. An increase in long-term migration in endothelial cells was observed and suggested that EHD2 impacts the RhoA pathway instead of the Rac1 pathway. This lead to the hypothesis that EHD2 controls a part of the RhoA pathway. This hypothesis is supported by the loss of filamentous actin and an increase in serrated junctions in cells …

Responses Of Arthropods To Fire And How Pollinators And Pollination Services Are Affected By Fire Severity, Blyssalyn V. Bieber

Electronic Theses and Dissertations

Fires impact ecosystems globally and due to climate change, there are shifts in fire regimes that impact ecological communities which provide essential ecosystem services. Focusing on arthropods, fire can influence this ubiquitous animal group in various way. We performed a comprehensive meta-analysis evaluating how fires impact differing arthropod functional groups. We found that overall, fire negatively effects community level responses for most functional groups with herbivores as the only exception showing some positive effects of fire. We also studied mixed-severity fires that burned >20 years ago and compared floral visitor communities across fire severities. We implemented a pollinator exclusion experiment …

Characterization Of Cyclopropyl Synthases Involved In The Maturation Of Ribosomally Synthesized And Posttranslationally Modified Peptides, Yi Lien

Electronic Theses and Dissertations

Ribosomally synthesized and post-translationally modified peptides (RiPPs) are a large class of natural products with significant human health implications. RiPPs are synthesized from a genetically encoded precursor peptide that undergoes significant modifications by maturing enzymes, or maturases. Recently, radical-S-adenosylmethionine (rSAM) enzymes have emerged as an important family of RiPP maturases. rSAM enzymes have been shown to install ether, thioether, and carbon-carbon bonds on the precursor peptide. These modifications usually define the backbone structure of the mature RiPP. This thesis describes the characterization of a novel RiPP modification catalyzed by the radical S-adenosylmethionine enzyme TigE. TigE belongs to the TIG biosynthetic …

Exploring The Lives Of Parents Of Traditionally Marginalized Gifted Students, Lora Romero

Electronic Theses and Dissertations

The purpose of this study was to examine the lived parenting experiences of traditionally marginalized gifted students within the educational setting and at home. For this study, the researcher gathered information from seven parents of traditionally marginalized gifted students and told their stories. Since the families are traditionally marginalized the population consisted of those who have high intelligence and are a part of a historically oppressed racial/ethnic group. The study was developed using the lens of the Critical Race Theory (CRT). Through the CRT, Capper (2015), recognized that many schools analyze the function of race but lack the knowhow of …

Could Alexa Increase Your Social Worth?, Peter Tripp

Electronic Theses and Dissertations

People have historically used personal introductions to build social capital, which is the foundation of career networking and is perhaps the most effective way to advance a career (Lin, 2001). With societal changes, such as the pandemic (Venkatesh & Edirappuli, 2020), and the increasing capabilities of Artificial Intelligence (AI), new approaches may emerge that impact societal relationships. Social capital theory highlights the need for reciprocal agreements to establish the trust between parties (Gouldner, 1960). My theoretical prediction and focus of this research include two principles: The impact of reciprocity in evaluating trust of the source of the introduction and the …

An Intersectional Perspective On The Role Of Workplace Policy Among Employed Female Caregivers During The Coronavirus Pandemic, Jessica King Mclaughlin

Electronic Theses and Dissertations

Providing care for an older adult while working can be challenging, often leading to caregiver burden. The socioenvironmental context of the coronavirus pandemic creates additional complications for working caregivers. Women, who are the majority of informal caregivers, face unique stressors in the workplace (McKinsey & Company, 2019; Carnevale et al., 2018). Prior to and during the coronavirus pandemic, workplace policies have offered the potential of support, yet more information is needed on how working female informal caregivers of older adults of diverse identities receive, interpret, and experience these policies amidst the context of the pandemic. This study uses a phenomenological …

Improving Quantification Of Mitral Regurgitation Through Computational Fluid Dynamics And Ex Vivo Testing, Alexandra Flowers

Electronic Theses and Dissertations

Mitral regurgitation (MR) is a prominent cardiac disease affecting more than two million people in the United States alone. In order for patients to receive proper therapy, regurgitant volume must first be quantified. As there are an array of methods to do so, the proximal isovelocity surface area (PISA) method continues to be the most accurate and clinically used method. However, there are some difficulties obtaining the necessary measurements need for this when performing transthoracic echocardiography. This study aims to evaluate and present techniques that may be used to more accurately quantify regurgitation through ex vivo testing and computational fluid …

Perceptions Of Parental Care And Overprotection In Childhood: Influences On The Neurobiological Adaptation To Motherhood, Leah Grande

Electronic Theses and Dissertations

Recalled memories of caregiving in childhood are especially salient during the postpartum period and inform mothers’ conceptualization of her new parenting role. Positive perceptions of care received from one’s parents are related to improved maternal-infant bonding and positive parenting behaviors, whereas negative perceptions of care convey risk for maladaptive parenting. Few studies have investigated neural and biological mechanisms contributing to observed associations between childhood care and the adaptation to motherhood. The following studies address this gap by examining how perceptions of childhood parental care and overprotection are related to maternal behavior, oxytocin levels, and neural response. Methods: Perceived childhood maternal …

Assessing The Relationship Between White Privilege, White Fragility, And Masculine Gender Identity And Stressors In The Workplace, Anna Edelman

Electronic Theses and Dissertations

The current study examined how White privilege information avoidance and White fragility are related to aspects of traditional masculinity. Informed by Critical Race Theory and Critical Whiteness Studies, this study examined the link between traditional masculine norms, masculine gender identity stress, and White privilege reactions. A sample of White, working men were recruited both through snowball sampling and Amazon’s Mechanical Turk. Participants were first assessed on a variety of masculinity variables and then were randomly assigned to view one of two video vignettes. After viewing this video, their affective responses, White privilege information avoidance, and White fragility were assessed through …

Classification Of Electropherograms Using Machine Learning For Parkinson’S Disease, Soroush Dehghan

Electronic Theses and Dissertations

Parkinson’s disease (PD) is a neurodegenerative movement disorder that progresses gradually over time. The onset of symptoms in people who are suffering from PD can vary from case to case, and it depends on the progression of the disease in each patient. The PD symptoms gradually develop and exacerbate the patient’s movements throughout time. An early diagnosis of PD could improve the outcomes of treatments and could potentially delay the progression of this disorder and that makes discovering a new diagnostic method valuable. In this study, I investigate the feasibility of using a machine learning (ML) approach to classify PD …
