Foraging In Marine Habitats Increases Mercury Concentrations In A Generalist Seabird, Corey A. Clatterbuck, Rebecca L. Lewison, Rachael A. Orben, Joshua T. Ackerman, Leigh G. Torres, Robert M. Suryan, Pete Warzybok, Jaime Jahncke, Scott A. Shaffer

Faculty Research, Scholarly, and Creative Activity

Methylmercury concentrations vary widely across geographic space and among habitat types, with marine and aquatic-feeding organisms typically exhibiting higher mercury concentrations than terrestrial-feeding organisms. However, there are few model organisms to directly compare mercury concentrations as a result of foraging in marine, estuarine, or terrestrial food webs. The ecological impacts of differential foraging may be especially important for generalist species that exhibit high plasticity in foraging habitats, locations, or diet. Here, we investigate whether foraging habitat, sex, or fidelity to a foraging area impact blood mercury concentrations in western gulls (Larus occidentalis) from three colonies on the US west coast. …

Use Of Live And Robotic Assistance Animals For Psychological And Cognitive Health In Military Populations, Rachelle M. Cross

Dissertations

This literature review addresses the use of live and robotic animal-assisted therapy for psychological and cognitive health in military populations. More specifically, this literature review aims to address the benefits and limitations of the use of live animal-assisted therapy, complementary and alternative techniques (i.e., Combat and Emotional Stress Control Dogs and social robots) for military personnel, and possible attitudinal barriers regarding active duty and veteran soldiers, while utilizing literature conducted with the civilian population to augment. A systematic review of peer-reviewed quantitative and qualitative publications and book chapters was utilized to accomplish this. Results of the literature review indicated that …

An Evaluation Of Equity And Access For All Students In A School District's Career And Technical Education Programs, Cynthia M. Jaime

Dissertations

There is a great deal of research regarding the need for equity and access in Career and Technical Education (CTE); however, very little research exists acknowledging strategies to achieve it. The purpose of this study was to evaluate equity and access in CTE programs, as well as to determine any barriers to CTE program enrollment, participation, and completion faced by students identified as economically challenged, students with disabilities, or English language learners. The context of this inquiry was high school CTE programs in one school district in the United States of America. My study demonstrates both qualitative and quantitative data …

Desire, Culture, And The Body, Zoey Lavallee

Dissertations, Theses, and Capstone Projects

What is the nature of desire? In this dissertation I develop a theory of desire according to which desires are essentially enculturated states that play the role of presenting favorable outcomes that act as inputs to intention formation, and thereby intentional action. This analysis of desire debunks a common assumption shared by prominent accounts of desire in philosophy of mind, what can be called the dualist assumption: that bodily desires such as urges and appetites differ in kind from conceptual desires that are typically described as higher cognitive attitudes. I argue that the desires traditionally understood as bodily or appetitive …

Pilot Study Of The Effects Of Mobile Based Resonant Frequency Breathing On Cognitive Performance In Healthy Young Adults With Elevated Stress, Daniel Saldana

Dissertations, Theses, and Capstone Projects

Objective: Prior research has shown a bidirectional relationship between breathing, emotions, behavior, and cognitive functions thought to be mediated by the autonomic nervous system (ANS). Studies have shown that deep or diaphragmatic breathing interventions are associated with improved affect and decreased stress levels, but little attention has been paid to the effects of breathing training on cognition. The few studies that have looked at this have shown improved attention, memory, and executive functioning as a result of breathing interventions. While suggestive of positive benefits, these studies used control groups that are either inactive or inappropriate for determining their respective mechanisms …

Evaluating The Vulnerability Of Farming Communities To Winter Storms In Iowa, Us, Yiyi Zhang, Bingquing Liang

Faculty Publications

Winter storms have been reported as the second-most frequent catastrophe in the Midwest of the United States and can create non-negligible impacts on farming communities that highly rely on climatic-sensitive resources and activities. However, few studies have attempted to assess the vulnerability to winter storms in rural contexts. Focusing on all counties in Iowa, US, as the study area, this research aimed to evaluate the vulnerability of farming communities to winter storms and its major determinants. It first identified both climatic and non-climatic indicators for quantifying winter storm exposure, sensitivity, and adaptive capacity by reviewing previous related studies and examining …

Black-Throated Gray Warbler In Knox County, Nebraska, Mark A. Brogie

Nebraska Bird Review

The Nebraska Ornithologists’ Union Records Committee (NOURC) considers Black-throated Gray Warbler (Setophaga nigrescens) to be Accidental in Nebraska (NOURC 2017). Silcock and Jorgensen (2020) list a total of seven accepted records with only two occurring in fall: an adult male at the Hyannis Cemetery, Grant Co., 01 Sep 2002 (Brogie 2003) and a female at Oliver Reservoir, Kimball Co., 07 Sep 2001 (Silcock 2001). The following documents the third Nebraska fall record for Black-throated Gray Warbler, the third record east of the Nebraska Panhandle, the first for northeast Nebraska, and the only NOURC accepted record (#2338) in the last decade.

Waterfowl Use Of Wetland Habitats Informs Wetland Restoration Designs For Multi-Species Benefits, Michael L. Casazza, Fiona Mcduie, Scott Jones, Austen A. Lorenz, Cory T. Overton, Julie Yee, Cliff L. Feldheim, Joshua T. Ackerman, Karen M. Thorne

Faculty Research, Scholarly, and Creative Activity

Extensive global estuarine wetland losses have prompted intensive focus on restoration of these habitats. In California, substantial tracts of freshwater, brackish and tidal wetlands have been lost. Given the anthropogenic footprint of development and urbanization in this region, wetland restoration must rely on conversion of existing habitat types rather than adding new wetlands. These restorations can cause conflicts among stakeholders and species that win or lose depending on identified restoration priorities. Suisun Marsh on the San Francisco Bay Estuary is the largest brackish marsh on the US Pacific coast. To understand how conversion of brackish managed wetlands to tidal marsh …

Noninvasive Electrocardiographic Imaging (Ecgi) To Guide Catheter Ablation Of Scar-Related Ventricular Tachycardia, Omar Ahmed Gharbia

Theses

Scar-related VT is caused by local \textit{short circuits} of electrical propagation formed by slow-conducting channels of surviving tissue within a scar. Catheter ablation treats scar-related VT by destroying the critical channel of surviving tissues. Its efficacy heavily relies on how well the channels critical to the formation of VT circuits can be localized. Unfortunately, in current practice, this relies on invasive catheter mapping that falls short in several critical aspects: up to 90$\%$ of the VT circuits are too short-lived to be mapped, the mapping cannot be done non-invasively prior to the ablation procedure, and the mapping is restricted to …

Exogenous Inter-Α Inhibitor Proteins Prevent Cell Death And Improve Ischemic Stroke Outcomes In Mice, Louise D Mccullough, Meaghan Roy-O'Reilly, Yun-Ju Lai, Anthony Patrizz, Yan Xu, Juneyoung Lee, Aleah Holmes, Daniel C Kraushaar, Anjali Chauhan, Lauren H Sansing, Barbara S Stonestreet, Liang Zhu, Julia Kofler, Yow-Pin Lim, Venugopal Reddy Venna

Faculty, Staff and Students Publications

Inter-α inhibitor proteins (IAIPs) are a family of endogenous plasma and extracellular matrix molecules. IAIPs suppress proinflammatory cytokines, limit excess complement activation, and bind extracellular histones to form IAIP-histone complexes, leading to neutralization of histone-associated cytotoxicity in models of sepsis. Many of these detrimental processes also play critical roles in the pathophysiology of ischemic stroke. In this study, we first assessed the clinical relevance of IAIPs in stroke and then tested the therapeutic efficacy of exogenous IAIPs in several experimental stroke models. IAIP levels were reduced in both ischemic stroke patients and in mice subjected to experimental ischemic stroke when …

Continuous-Flow Left Ventricular Assist Device Support In Patients With Ischemic Versus Nonischemic Cardiomyopathy, Brendan P Chou, Andre Critsinelis, Harveen K Lamba, Gregory Long, Andrew B Civitello, Reynolds M Delgado, Subhasis Chatterjee

Faculty, Staff and Students Publications

To determine whether the cause of cardiomyopathy affects outcomes in patients who undergo continuous-flow left ventricular assist device support, we compared postimplant adverse events and survival between patients with ischemic and nonischemic cardiomyopathy. The inclusion criteria for the ischemic group were a history of myocardial infarction or revascularization (coronary artery bypass grafting or percutaneous coronary intervention), ≥75% stenosis of the left main or proximal left anterior descending coronary artery, or ≥75% stenosis of ≥2 epicardial vessels. From November 2003 through March 2016, 526 patients underwent device support: 256 (48.7%) in the ischemic group and 270 (51.3%) in the nonischemic group. …

Sex Chromosome Evolution Among Amniotes: Is The Origin Of Sex Chromosomes Non-Random?, Lukáš Kratochvíl, Tony Gamble, Michail Rovatsos

Biological Sciences Faculty Research and Publications

Sex chromosomes are a great example of a convergent evolution at the genomic level, having evolved dozens of times just within amniotes. An intriguing question is whether this repeated evolution was random, or whether some ancestral syntenic blocks have significantly higher chance to be co-opted for the role of sex chromosomes owing to their gene content related to gonad development. Here, we summarize current knowledge on the evolutionary history of sex determination and sex chromosomes in amniotes and evaluate the hypothesis of non-random emergence of sex chromosomes. The current data on the origin of sex chromosomes in amniotes suggest that …

The New Age Of Christian Healing Ministry And Spirituality: A Meta-Synthesis Exploring The Efficacy Of Christian-Adapted Complementary Therapies For Adult Survivors Of Familial Trauma, Amanda Lynne Brees

Doctoral Dissertations and Projects

Adult survivors of familial trauma present with many seemingly unrelated psychiatric and relational issues well into adulthood. Developmental and familial trauma is emerging in the research as a subset of complex posttraumatic stress disorder (C-PTSD). This specific type of trauma is rooted in attachment and family systems theory. Issues such as divorce, parental substance abuse, mental illness, enmeshment, parentification, abandonment, and abuse get passed down intergenerationally in vicious cycles until someone finds the courage to heal. Pastoral counselors are uniquely equipped to lead the third wave of cognitive-behavioral therapies proving effective in treating complex trauma includes mindfulness and complementary therapies …

Finding A Rule-Based Solution To The Appellate Body Crisis: Looking Beyond The Multiparty Interim Appeal Arbitration Arrangement, Henry S. Gao

Research Collection Yong Pung How School Of Law

The WTO dispute settlement system is in crisis due to the persistent blockage of the appointment of Appellate Body members by the United States. This paper reviews the US criticisms against the Appellate Body and argues that its allegations are unfounded and its approach is wrong. To deal with the US blockage, various proposals have been made, with the most popular being the Multiparty Interim Appeal Arbitration Arrangement (MPIA) set up by several key Members including the European Union and China. After a thorough analysis of the key features of the MPIA from both theoretical and practical perspectives, this paper …

Beyond The Mathematics Major: Identifying The Pedagogical Content Knowledge Exhibited By Preservice Secondary Mathematics Teachers, Steven R. Turner

Theses and Dissertations

The purpose of this study was to identify and characterize the pedagogical content knowledge (PCK) held by secondary mathematics preservice teachers. Task-based interviews were conducted to determine whether evidence of PCK exists in preservice teachers and, if so, what form that evidence took. Participants included preservice teachers near the end of their coursework and mathematics majors, whose experience ranged from having completed the calculus sequence to their first year in graduate school. Some experienced teachers were also included, allowing a comparison of their knowledge with the other groups. In this study I seek to gain a better understanding of the …

Emergency Procurement And Responses To Covid-19: The Case Of Singapore, Henry S. Gao

Research Collection Yong Pung How School Of Law

As one of the busiest trade and travel hubs in the world, Singapore quickly became the worst affected of all countries by COVID-19 in the very early stages of the pandemic. For example, on 5 February 2020, two weeks after the unprecedented lockdown in Wuhan by the Central Government of China, Singapore had the highest infection rate (24 cases out of a population of 5 million) in the world, higher than China (20,502 cases out of a population of 1.5 billion).1 Alongside the health emergency, Singapore also had to cope with another emergency as countries around the world, in a …

Perceiving The Body: On The Bodily Senses And The Nature Of Perception, Fiona C. Schick

Dissertations, Theses, and Capstone Projects

Visual perception dominates the philosophical study of perception. This dissertation shows that a complete understanding of the nature of perception as a general category requires a consideration of the nature of the bodily modalities such as interoception, proprioception, pain, touch, and thermoception. By understanding these modalities, we come closer to understanding the nature of perception (what it is, how it works, and what systems it encompasses). While non-visual modalities have been gaining more attention in philosophy, much of this work looks to philosophical issues particular to these modalities—not necessarily how they relate to questions about the nature of perception in …

Connecting Communities To Coastal Resilience: Enhancing Sustainability Through Public Participation In Salt Marsh Management And Restoration In Suffolk County, Ny, Jennifer L. Mcgivern

Dissertations, Theses, and Capstone Projects

Coastal resiliency is becoming significantly more critical to the livelihood of coastal communities as the frequency and intensity of storm events increases and is exacerbated by rising sea levels due to climate change. In October 2012 Superstorm Sandy impacted the New York-New Jersey area costing over $70 billion in storm damages and 147 lives lost, as storm surges surpassed record highs for the region. Protruding more than 100 miles into the Atlantic Ocean with over 1,000 miles of shoreline, Long Island is particularly vulnerable to the increasingly ferocious and numerous storms as well as the rising sea levels that climate …

Effects Of Prenatal Cannabis Exposure On Offspring Emotional Development And Stress Response, Alexandra Pritchett

Dissertations, Theses, and Capstone Projects

While cannabis may be used by women during pregnancy, its effects on their offsprings’ developing stress response system are still largely unknown. The binding sites for the active chemicals in cannabis are operational at early time points in fetal development and are expressed in key limbic brain structures. The body’s natural endocannabinoid system serves as an important regulator of the stress response. Longitudinal studies have associated prenatal exposure with increased fearfulness and mood disturbances in offspring, but, despite the growing evidence of emotional dysfunction, there remains a critical gap in knowledge explaining how early prenatal exposure may lead to future …

Machine Learning And Solvation Theory For Drug Discovery, Lieyang Chen

Dissertations, Theses, and Capstone Projects

Drug discovery is a notoriously expensive and time-consuming process; hence, developing computational methods to facilitate the discovery process and lower the associated costs is a long-sought goal of computational chemists. Protein-ligand binding, which provides the physical and chemical basis for the mechanism of action of most drugs, occurs in an aqueous environment, and binding affinity is determined not only by atomic interactions between the protein and ligand but also by changes in their interactions with surrounding water molecules that occur upon binding. Thus, a quantitative understanding of the roles water molecules play in the protein-ligand binding process is an essential …

Navigating Ocha: Lgbt Practitioners' Participation And Navigation Of Lucumí, Carlos M. Camacho

This work uses qualitative interviews and ethnographic observations to look at how LGBT people navigate ritual space and people politics in Lucumí. As part of contemporary social shifts, many are seeking alternative spaces of spiritual practice and that includes LGBT people. LGBT people and trans people in particular are seeking Lucumi and being drawn in, this dissertation looks at some of these mechanisms. In addition, this dissertation looks at how home is created or …

Spectral Urbanism: Modern Ghost Cities, Rare Earths, And Political Time At The Limits Of Materialism, Linsey Ly

Dissertations, Theses, and Capstone Projects

Contemporary urbanization in China is marked by speed, repetition, and similitude, key features of what I call spectral urbanism that also attends to the presence or absence, to recursivity and deferral. The mass development of empty, outmoded, and seemingly abandoned modern ghost cities in China’s borderlands come to be used as evidence of an interruption or lack in the veneer of Chinese modernity. The contours and quality of stalled development are measured, read in objects of the built environment that have yet to fulfill their anticipated function: vacant buildings, quiet roads that lead no one to empty parks, homes which …

Longitudinal Changes Of Regional Myelin Water Fraction During First Year After Moderate-To-Severe Diffuse Traumatic Brain Injury, Likowsky L. Desir

Dissertations, Theses, and Capstone Projects

Traumatic brain injury (TBI) is a worldwide health issue with a highly heterogeneous disease characterization, including widespread white matter damage in the brain. Most non-invasive white matter imaging methods currently available, including diffusion tensor imaging (DTI), cannot reliably measure the degree of neurodegeneration due to various confounds, making it challenging to select an endpoint measure for neuroprotective clinical trials. The present study investigates longitudinal white matter changes, measured by a novel imaging metric, apparent myelin water fraction (aMWF), and its relationship with neuropsychological measures during the first year after TBI. Data from 15 adult patients with moderate-to-severe TBI and 30 …

The Problem Of Leisure: A Modern History Of Work And Idleness, Lea S. Sanchez

Dissertations, Theses, and Capstone Projects

As our leisure time has increased in the twenty-first century, paradoxically, so too have social and cultural expectations about the nature and value of work. In this thesis, I argue that work in the modern world has taken on new shapes – the project of identity formation, image maintenance, and receptiveness to advertising – and how these new forms of work are fundamentally intertwined with leisure. I first aim to establish a timeline of Western attitudes to work, beginning with the works of Max Weber, Jon D. Wisman, and Matthew E. Davis. Then, through the lens of the 1970s punk …

The Effect Of Psilocybin On Personality, Ravital Labua

Dissertations, Theses, and Capstone Projects

As classic psychedelics are increasingly legalized and reintroduced into the psychotherapeutic frame, a deeper understanding of their effect on personality and overall wellbeing - as well as their clinical contraindications and potential pitfalls - will prove essential. As a result, this study represents a preliminary investigation into the effect of psilocybin exposure on a range of personality constructs.

Methods: Data was collected through a collaboration with The Psychedelic Society, an organization that legally administers psilocybin truffles in the Netherlands to self-selecting retreat attendees who have been screened for mental health disorders in accordance with Johnson et al.’s (2008) widely accepted …

The Psychological Allure Of Alford: Why Innocents Plead Guilty, Johanna Hellgren

Dissertations, Theses, and Capstone Projects

The Alford plea allows defendants to maintain their innocence while accepting a plea. Although this plea is more prevalent than jury trials, it is largely unknown to both lay people and researchers (Redlich & Özdoğru, 2009). Legal scholars have argued that the Alford plea may present an undue influence on innocent defendants who may not otherwise accept a plea, while other assert that the Alford plea is a beneficial alternative for defendants who want to preserve their reputation (Ronis, 2009; Ward, 2004). However, no research to date has explored either of these assumptions.

The goals of the current research were …
