Grid Independence Studies Of Eddy-Resolving Models At The Scale Of A River Reach Along A Transect In Marble Canyon Of The Colorado River, Arizona, Rosa Elena España Urresty

Open Access Theses & Dissertations

This study presented a novel approach for evaluating the impact of changes in spatial resolution on field-scale models to identify turbulent flow patterns in hydraulic features in canyon-bound rivers. The methodological framework incorporated seven different computational domain resolutions to analyze the sensitivity of field-scale models to spatial resolution changes by employing techniques such as turbulent kinetic energy spectrum, spatiotemporal analysis of eddy structures, divergent Kullback-Leibler (KL) divergence, Nash-Sutcliffe (NS) model efficiency coefficient, wavelet power spectrum, and GCI calculation. Statistical and physical-based skill metrics are employed to quantifying information loss to evaluate a set of domain resolutions. Grid independence studies have …

Statewide Assessment Reveals Spatiotemporal Variability Of Iron In Iowa Lakes, Tania Leung, Elizabeth D. Swanner

Journal of Contemporary Water Research and Education

The micronutrient iron has been noted to play a crucial role in regulating phytoplankton growth; however, most studies have focused on large lakes with persistent phytoplankton blooms that are known to undergo iron limitation, such as Lake Erie. Iron abundance in boreal lakes is also known to correlate with dissolved organic carbon and increased iron concentrations causing "browning." To assess the spatial distribution of dissolved Fe (DFe) in lakes throughout Iowa, a landscape once dominated by prairies, DFe was measured in surface waters of 124 lakes distributed across the state over the 2018 summer season. Thirty lakes were selected for …

Continuous Hydrologic Modeling Of A Parking Lot And Related Best Management Practices With Pcswmm, Robson L. Pachaly, Don Guy V.V. Biessan, Jose G. Vasconcelos, Frances C. O'Donnell, Benjamin F. Bowers

Journal of Contemporary Water Research and Education

Permeable pavements are a green infrastructure stormwater management practice that can serve as a functional component of the site design. However, previous field studies suggest high uncertainty in the parameters used for performing hydrologic calculations for permeable pavements. The Environmental Protection Agency (EPA) Storm Water Management Model (SWMM) within the PCSWMM software package was used to simulate the hydrologic dynamics of a parking lot that is 25% covered with permeable interlocking concrete pavers in Auburn, AL. The model was calibrated to field observations of water level at two points where the pavement system outflows to a bioretention basin and rainfall …

Spatiotemporal Variability Comparisons Of Water Quality And Escherichia Coli In An Oklahoma Stream, Grant M. Graves, Jason R. Vogel

Journal of Contemporary Water Research and Education

Fecal indicator bacteria, Escherichia coli, for primary body contact recreation (PBCR) in Oklahoma waterbodies, is defined as the geometric mean of 10 samples from the recreation season, May 1 to September 30, with an impairment threshold of 126 colony forming units (cfu) per 100 mL. However, the water quality standards provide limited guidance on spatiotemporal and environmental factors that could influence samples collected and analyzed. In this study, two stream cross sections under baseflow conditions in a central Oklahoma urban perennial stream, Spring Creek, were densely sampled to investigate temporal and spatial variability of E. coli concentrations and water quality …

Total Microcystin Concentration Variability In Water Samples And Recommended Minimum Volume (20 Ml) For Freeze Thaw Cycles, Brian E. Haggard, Bradley J. Austin

Journal of Contemporary Water Research and Education

Cyanobacterial harmful algal blooms (cyanoHABs) continue to be a monitoring and research focus, particularly on the occurrence of toxins like total microcystins. The objectives of this study were to evaluate sampling and analytical variability in measured total microcystin concentrations and then to evaluate the volume of raw water needed in the freeze thaw cycle to reduce sampling variability. Water samples were collected from a recreational lake with annual cyanoHABs, and then 2 mL was used in freeze thaw cycles before total microcystin analysis. Then, sample volumes used in the freeze thaw cycles varied from 2 to 300 mL for total …

Diversity, Equity, Inclusion, And Justice In Water Dialogues: A Review And Conceptualization, Simone A. Williams, Susanna Eden, Sharon B. Megdal, Valerisa Joe-Gaddy

Journal of Contemporary Water Research and Education

In the United States, the lack of diversity, equity, inclusion, and justice (DEIJ) in water governance and management has been identified as a serious problem that affects the validity of decisions. Because water governance and management institutions, processes, and practices at all scales involve dialogue, it is important to understand DEIJ in water dialogues. This paper reports on the results of a systematic literature survey that was undertaken to guide efforts by The University of Arizona Water Resources Research Center to improve diversity and inclusion in its engagement practices and outreach strategies. Three questions are explored: 1) How is DEIJ …

Co-Alteration Network Architecture Of Major Depressive Disorder: A Multi-Modal Neuroimaging Assessment Of Large-Scale Disease Effects, Jodie P. Gray, Jordi Manuello, Aaron F. Alexander-Bloch, Cassandra Leonardo, Crystal Franklin, Sueng Choi, Franco Cauda, Tommaso Costa, John Blangero, David C. Glahn, Peter T. Fox

School of Medicine Publications

Major depressive disorder (MDD) exhibits diverse symptomology and neuroimaging studies report widespread disruption of key brain areas. Numerous theories underpinning the network degeneration hypothesis (NDH) posit that neuropsychiatric diseases selectively target brain areas via meaningful network mechanisms rather than as indistinct disease effects. The present study tests the hypothesis that MDD is a network-based disorder, both structurally and functionally. Coordinate-based meta-analysis and Activation Likelihood Estimation (CBMA-ALE) were used to assess the convergence of findings from 92 previously published studies in depression. An extension of CBMA-ALE was then used to generate a node-and-edge network model representing the co-alteration of brain areas …

Images In Service Marketing: Does Presentation Style Matter?, Can Trinh

Atlantic Marketing Journal

This research presents a pioneering attempt to examine whether the use of abstract images would be more effective than the use of concrete images in the case of service marketing. Based on construal level theory, we hypothesize that relative to the use of concrete images, the use of abstract images in service marketing will better match the intangible nature of services and will thus increase communication effectiveness. Two studies in this research provide evidence to support these propositions by showing that relative to the use of concrete images, the use of abstract images can enhance ad visuals, which in turn …

Marketing Orientation: A Longitudinal Study Of Community Banks, Stephen C. Carlson, Gerald Sullivan, Susanna Warnock, Margaret Ryder

Atlantic Marketing Journal

Marketing orientation has long been touted as a means of improved business performance and a key to success in marketing management (Kotler, Keller & Chernev, 2021). This is a longitudinal study of community banks examining marketing orientation and business performance using a survey instrument based on the work of Narver and Slater (1990) and Kohli and Jaworski (1990).

Four survey datasets cover the period preceding the Great Recession (2003-2005), the Great Recession and its fallout (2008-2010), a Post–Great Recession period (2014-2016), and the COVID-19 period (2020). Survey responses were gathered from a selected set of community bank CEOs in the …

Nation Branding Through Sports: The Impact Of Qatar’S Ownership Of Paris Saint-Germain (Psg) On Qatar’S Image By French Soccer Fans, Matthieu Bocquet, Vassilis Dalakas

Atlantic Marketing Journal

This study examined how French soccer fans perceive Qatar which owns French club Paris Saint-Germain (PSG). It compared perceptions of the country among PSG fans, fans of PSG’s rival club Olympique Marseille (OM), and fans of other French clubs. Furthermore, it examined how fans’ identification with PSG or its rival OM moderated their perceptions of Qatar. PSG fans had more favorable perceptions than the other fans and highly identified PSG fans had more positive perceptions than low-identification PSG fans. However, rival fans did not have more negative perceptions than the other fans and there was also no difference between highly …

The Impact Of Insult Ad Reads On Podcast Listeners, Jason L. Snyder, Mark D. Cistulli

Atlantic Marketing Journal

Audio podcasts have grown in popularity. Forty-six million Americans tune into an average of six podcasts each week (Nielson, 2020) and ad revenues are projected to top $4 billion by 2024 (IAB, 2022). To enhance the appeal of ads, many podcasters use humor in their ad reads. Although humor can be effective (Weinberger & Gulas, 1992) and reinforce the parasocial relationship between podcaster and audience, are there times when that humor has negative consequences? In this study, we are concerned primarily with the use of insult advertising in which the podcaster uses humor that targes the brand/product being endorsed. Participants …

The Membership Business Model: Great For Business But What About Consumers?, Cara Peters, Bradley W. Brooks

Atlantic Marketing Journal

Membership business models are increasingly prevalent, as they appear to be beneficial to companies. However, questions exist about the benefits of the membership business model to consumers. This paper examines consumer perspectives on the membership business model in the context of customer complaints related to Savage X Fenty’s business practices. Data were collected via 692 complaints posted to the Better Business Bureau website and analyzed according to protocols for phenomenology. Eight themes emerged from the data, beginning with membership sign-up and ending with being charged after-the-fact. The themes captured the different frustrations that consumers experienced with Savage X Fenty’s membership …

The Regional Mall’S Persona Wish List: The Hedonist, The Influencer And The Local Champion, Thomas M. Hickman, Michael Stoica, David P. Price

Atlantic Marketing Journal

This study investigates three consumer archetypes (hedonist, influencer, and local champion) and their potential to influence mall revitalization. Results show that a belief in the importance of the mall leads to a more enjoyable shopping experience, a subsequent willingness to pay more for locally owned stores, a greater propensity to spend more at the mall, and to engage in positive word-of-mouth. Findings suggest that local champions and influencers are vital for bringing patrons back to shopping centers in the aftermath of the COVID-19 pandemic. It is argued that the mall and its tenants will benefit from co-marketing; the mall offering …

Happy Campers Or Unhappy Prisoners: How Materialism Punishes Us In Lockdown Times, Banwari Mittal

Atlantic Marketing Journal

COVID-19 and the resulting lockdowns created an unprecedented upheaval in consumers’ daily lives and lifestyles. The purpose of this research was to understand the psychological experience of life under lockdowns and the role of individual difference variables in that experience. Using survey data from U.S. consumers, the research identified two opposite feelings, coexisting: happy camper feeling or unhappy prisoner feeling. Younger, lower income, and less educated consumers felt more like prisoners than campers. Ability to maintain life as usual, and positive pre-pandemic life conditions (health, social network, and job satisfaction) led to happy camper feelings. In contrast, pre-pandemic materialism led …

Identifying Dynamic Patterns Of Polypharmacy For Patients With Dementia From Primary Care Electronic Health Records: A Machine Learning Driven Longitudinal Study, Elisabetta Longo, Bruce Burnett, Sarah Bauermeister, Shang Ming Zhou

School of Nursing and Midwifery

It is unclear how medication use evolved before diagnosis of dementia (DoD). This study aims to identify varied patterns of polypharmacy before DoD, their prevalence and possible complications. We collected primary care e-health records for 33,451 dementia patients in Wales from 1990 to 2015. The medication uses in every 5-year period along with 20-years prior to dementia diagnosis were considered. Exploratory factor analysis was used to identify clusters of medicines for every 5-year period. The prevalence of patients taking three or more medications was 82.16%, 69.7%, 41.1% and 5.5% in the Period 1 (0-5 years before DoD) ~ Period 4 …

Deciding For Others: Local Public Good Contributions With Intermediaries, Andrej Angelovski, Praveen Kujal, Christos Mavridis

ESI Working Papers

Given the prevalence of local public goods, whose broader use is often limited by distance and borders, we propose a potential solution to the free-riding problem by having each participant/beneficiary delegate the public good contribution decision to a non-local intermediary who neither puts in own endowment into the public good nor benefits from it. Intermediaries make decisions under two compensation mechanisms where the incentives for the intermediary are either non-aligned (fixed) or aligned (variable) with those of the beneficiary. We find that the use of intermediaries, regardless of whether their compensation is aligned or not with that of the beneficiary, …

Intracellular Zinc Trafficking During Crotalus Atrox Venom Wound Development, Eric A. Albrecht, Jasmine D. Carter, Veronica Garbar, Abeeha Choudhary, Scott A. Tomlins

Faculty Articles

In this study, we examined zinc trafficking in human umbilical vein endothelial cells (HUVEC) stimulated with Crotalus atrox (CA venom) snake venom. We utilized MTS cytotoxicity assays to monitor the cytotoxic range of CA venom. HUVEC monolayers stimulated with 10 µg/mL CA venom for 3 h displayed cellular retraction, which coincided with 53.0 ± 6.5 percent viability. In contrast, venom concentrations of 100 µg/mL produced a complete disruption of cellular adherence and viability decreased to 36.6 ± 1.0. The zinc probe Fluozin-3AM was used to detect intracellular zinc in non-stimulated controls, HUVEC stimulated with 10 µg/mL CA venom or HUVEC …

Bloom: A 21st Century Mandolin Concerto, Ashley Hoyer

Electronic Theses and Dissertations

I have created a career performing various types of music on the mandolin. Very little of the concert repertoire, however, includes music originally written for the mandolin with most of it consisting of rearrangements of violin, cello, or piano music. This observation has led me down a path to learn why there is a lack of mandolin concert repertoire as well as to create new music specifically written for the instrument. In this thesis, an original mandolin concerto, Bloom, aims not only to add to the instrument’s repertoire, but bring it into the twenty-first century using contemporary compositional techniques. I …

Gluten Free Diet Ameliorates Si Enteropathy In Iga Deficient Mice, Ryan Albert William Ball

Theses and Dissertations

Secretory IgA is the most abundant antibody in the intestinal mucosal and functions as the first line of defense against pathogens and micro-organisms in the gut. Selective IgA deficiency is the most common form of antibody deficiency. Clinically, IgA deficient patients are largely asymptomatic, they are however at a higher risk of developing certain inflammatory conditions like Celiac disease; an SI-specific enteropathy triggered by exposure to dietary gluten. Interestingly, celiac patients are 10-15 times more likely to have an IgA deficiency. Recent studies have shown that IgA^-/- mice develop enteropathy specifically in the ileum. We confirmed this phenotype in …

Examining Associations Between Social Needs And Mental Health Among Youth And Young Adults With Diabetes, Andrea Danielle Brown

Theses and Dissertations

Household food insecurity (HFI) disproportionally affects people with diabetes living in the United States and is more likely to occur in households with children and in minority race/ethnicity households. Food insecure people with youth-onset diabetes likely have increased risk for poor mental health due to dealing with stress and cost related to diabetes management, especially if facing additional health-related social needs that intersect with HFI. If left untreated, poor mental health among youth and young adults (YYA) with diabetes can lead to diabetes-related complications, increased health care costs, and mortality. Yet few studies have examined associations between HFI and mental …

Portrayals Of Roman Catholicism In North American Children’S And Adolescent Literature Following Vatican Ii, Kathleen Anna Carroll

Theses and Dissertations

While American children’s literature scholars have analyzed issues of Christianity broadly, and there are many considerations of Roman Catholicism within European children’s literature scholarship, there is a lack of scholarly discourse regarding Roman Catholicism within children’s literature published in the United States. This dissertation considers how North American children’s and adolescent literature approach the issues that preoccupied North American Roman Catholicism post-Vatican II as well as how such portrayals have impacted readers’ understanding of the faith during this vital period of transition within the Church. Chapter 1 focuses on the way young adult literature published in the early 1970s addressed …
