Turning Participation Into Power: A Water Justice Case Study, Jaime A. Lee

All Faculty Scholarship

This Article offers a revamped model of participatory governance—the Constituent Empowerment Model (CE Model)—which affirmatively shifts power to the voices of marginalized constituents so that they can influence governmental policy. The CE Model focuses on three concepts necessary to produce this shift in power to those who are traditionally unheard: operationalized (feasibly realized) participation; constituent primacy; and structural accountability. To illustrate how a CE system might be constructed, this Article examines a model recently adopted in the city of Baltimore, Maryland, that is designed to shift the balance of power between the water utility and its customers. Baltimore offers a …

Impactful Digital Technology: Connecting With Nature In Early Childhood, Kathleen A. White

Masters Projects

Young children are increasingly found to be spending their free time passively engaging with various types of digital technology. This has become one of the primary reasons why children’s time spent outdoors is diminishing. It has also led to an increase in negative health and developmental concerns. Children suffer from what has been deemed Nature Deficit Disorder, first coined by Richard Louv. Their lack of feeling connected with the natural world early on decreases the chances of them becoming a steward of that same world later in life. The studies have shown that although many believe young children should be …

Covid-19 Vaccine Hesitancy Among Non-Refugees And Refugees In Kenya, Ryan Rego, Anthony Ngugi, Antonia Johanna Sophie Delius, Stanley Luchters, Joseph C. Kolars, Furqan B. Irfan, Eileen Weinheimer-Haus, Amina Abubakar, Reena Shah, Ji Zhu

Population Health, East Africa

Factors associated with COVID-19 vaccine hesitancy (which we define as refusal to be vaccinated when asked, resulting in delayed or non- vaccination) are poorly studied in sub-Saharan Africa and among refugees, particularly in Kenya. Using survey data from wave five (March to June 2021) of the Kenya Rapid Response Phone Survey (RRPS), a household survey representative of the population of Kenya, we estimated the self-reported rates and factors associated with vaccine hesitancy among non-refugees and refugees in Kenya. Non-refugee households were recruited through sampling of the 2015/16 Kenya Household Budget Survey and random digit dialing. Refugee households were recruited through …

An Examination Of Public-School Discipline Policies And Implications For African American Students Within A Texas School District, Demeka Demeka Simmons

Dissertations (2016-Present)

National data illustrates that the use of exclusionary discipline practices has resulted in disproportionality and overrepresentation in school discipline. Additionally, research also illustrates that African Americans have been overrepresented in exclusionary discipline at higher rates than their White counterparts. The purpose of this study was to determine if there was a statistically significant difference in the percent of exclusionary discipline practices between African American students and White students based upon school district setting within Texas. The researcher analyzed archival data from 673 students in grades 3-12 enrolled in a Texas public school. The statistical tests used in the analysis of …

Police Militarization And Overuse Of Force: An Analysis Of The Efficacy Of Paramilitary Units And Society, Ronald R. Burnett

Dissertations (2016-Present)

The role of the police is to maintain social order and safety through the enforcement of law. They investigate, prevent, and detect criminal activity. However, the problem with police protection today is overuse of force which often comes through the term militarism regarding agency tenets and dogma. Also, social media has focused on police overuse of force, exacerbating race riots and retaliatory police killings. Because of this, police reform has become a significant concern, not only in the United States but also abroad. The methodological approach for this dissertation is a quantitative analysis, data used is secondary, statistical procedure is …

Parental Pains Of Imprisonment: A Critical Qualitative Examination Of Reentry Into Family Life, Mitchel B. Michael

Dissertations (2016-Present)

The purpose of this study is to grasp and become better informed about the experiences of formerly incarcerated mothers and fathers transitioning from correctional facilities (i.e., local jails, state & federal prisons) back into family life. Lacking in criminological literature on prisoner reentry is the intersection of parenthood and post-incarceration reintegration. Since available research often focuses on maternal and paternal reentry separately, this study encapsulates both to provide an in-depth analysis of experiences across race and gender. To gauge perspectives and experiences in-depth, this study is grounded in qualitative/triangulated methodologies. The data and findings from this study aim to assist …

Preclinical Development Of Novel Chemotherapeutic Agent Ac1lpszg: Formulation Optimization, In Vitro Characterization, And In Vivo Pharmacokinetics, Ritu Gupta

Dissertations (2016-Present)

Preclinical development of novel chemotherapeutic agent AC1LPSZG, a mammalian target of rapamycin (mTOR) inhibitor, involved development of sensitive reverse-phase ultra-performance liquid chromatography (UPLC) and LC-MS/MS methods for quantification of AC1LPSZG in in vitro study samples and rat plasma, respectively. Pharmacokinetic studies were done in SD rats after intravenous injection of cosolvent formulations. The resulting pharmacokinetic parameters were analyzed using non-compartmental analysis (NCA) and two-compartmental modeling. Poly (D, L-lactic-co-glycolic acid) (PLGA) is most used biodegradable synthetic polymer for nano drug delivery due to its non-toxic and biodegradable nature, and tunable release properties. PLGA nanoparticles (NPs) were prepared by ‘nanoprecipitation’ technique using …

What You See You Perceive: Public Opinions Of Potential Negative Consequences And Support For Officer Body-Worn Cameras, Jordyn Marian Sanders

UNLV Theses, Dissertations, Professional Papers, and Capstones

Officer-body worn cameras (BWCs) are used in policing to provide visuals from the perspective of the officer during interactions with the community. BWCs are often promoted for the ability to improve the relationship between the community and police by providing accurate and transparent accounts of the interactions. Millions of dollars have been spent to distribute BWCs to police departments across the Unites States, with an estimated 80% of departments implementing the devices through various policies and procedures (White & Malm, 2020). Most studies on BWCs have provided empirical evidence showing the potential benefits of the devices in policing (Lum et …

Using Teacher Noticing And Video-Mediated Professional Learning To Develop Preservice Teachers’ Knowledge For Teaching The Derivative, Alfred M. Limbere

Theses, Dissertations and Culminating Projects

This study investigated how problem-solving videos can be used in video-mediated professional learning to support secondary preservice mathematics teachers (PMTs) in developing teacher knowledge for noticing student thinking in the context of the derivative concept in calculus. A model of the trajectory of PMTs’ noticing was constructed as six PMTs viewed and analyzed videos of students’ problem solving. At the same time, the nature of video-mediated interactions that were found to be productive in supporting this knowledge development was examined. A design experiment was used as the research methodology. Data was collected from video recordings of eight semi-structured teaching episodes …

The Geriatric Nutritional Risk Index As A Predictor Of Complications In Geriatric Trauma Patients: Author Reply In Response To: “The Admission Serum Level Of Albumin Cannot Thoroughly Represent The Nutritional Status Of Trauma Patients”, Heather R Kregel, Patrick B Murphy, Mina Attia, David E Meyer, Rachel S Morris, Ezenwa C Onyema, Sasha D Adams, Charles E Wade, John A Harvin, Lillian S Kao, Thaddeus J Puzio

Faculty, Staff and Student Publications

BACKGROUND: Malnutrition is associated with increased morbidity and mortality after trauma. The Geriatric Nutritional Risk Index (GNRI) is a validated scoring system used to predict the risk of complications related to malnutrition in nontrauma patients. We hypothesized that GNRI is predictive of worse outcomes in geriatric trauma patients.

METHODS: This was a single-center retrospective study of trauma patients 65 years or older admitted in 2019. Geriatric Nutritional Risk Index was calculated based on admission albumin level and ratio of actual body weight to ideal body weight. Groups were defined as major risk (GNRI98). The primary outcome was mortality. Secondary outcomes …

Strategy For Generating Blinded Evidence For Single-Arm Trials With External Controls Using Expert Review Of Home Video, Bharti Manwani, Carson Finger, Lynda Lisabeth

Faculty, Staff and Student Publications

Stroke risk and prevalence increase with advanced age and women tend to be older than men at the time of their first stroke. Advanced age in women confers unique stroke risks that are beyond reproductive factors. Previous reviews and guidelines have largely focused on risk factors specific to women, with a predominant focus on reproductive factors and, therefore, younger to middle-aged women. This review aims to specifically describe stroke risk factors in elderly women, the population of women where the majority of strokes occur, with a focus on atrial fibrillation, hormone therapy, psychosocial risk factors, and cognitive impairment. Our review …

Diversity, Equity, And Inclusion: Three Essays In The Educational Context, James D. Paul

Graduate Theses and Dissertations

Many universities and K-12 public school systems express a significant, formal commitment to the ideals of diversity, equity, and inclusion (DEI). Relative to the emphasis on DEI in America’s educational institutions, however, there has been little research describing DEI trends and evaluating the efficacy of DEI bureaucracies. This three-chapter dissertation examines DEI trends that have been the subject of much discussion—but rarely studied empirically.

For example, chapter one analyzes how universities promote DEI when hiring new faculty. I audit a subset of academic job postings and present the first evidence on how many require DEI statements, as well as the …

Expression Of Claudins In Gill And Opercular Membranes In Relation To Osmoregulation In Euryhaline Atlantic Killifish, Fundulus Heteroclitus, Allison Mcfarland

Graduate Theses and Dissertations

Atlantic killifish (Fundulus heteroclitus) are euryhaline teleosts, which means they can thrive in environments with varying salinities, ranging from concentrated seawater (SW) to dilute fresh water (FW) and thus survive in estuaries. To be able to maintain ionic and osmotic homeostasis in these diverse salinities, osmoregulatory organs like gill and opercular membrane must be able to adjust the permeability and transport of water and ions. The surface epithelia in these organs need to prevent the passive flux of ions and water in a drastically changing environment, while being able to switch between active ion secretion or uptake dependent upon environmental …

Evaluation Of Life Cycle Costs, Benefits, And Public Perceptions Of Greywater Reuse Systems For Supplementing Conventional Water Delivery, Sreeganesh Reddy Yerri

All Dissertations

The water utility industry is under enormous pressure to meet the challenges of increasing demands due to population growth, lifestyle changes, and depleting freshwater resources. The current and predicted future deficit scenarios challenge water supply managers to come up with a sustainable and reliable alternative source while making the supply infrastructure smarter and resilient. One such alternative source is the greywater that is available at the point of consumption itself. With certain limitations, there have been studies performed to evaluate the life cycle costs and expected monetary benefits of decentralized greywater reuse systems, but the public and health bureaus are …

Feasibility Of Using Ultra-High-Performance Concrete (Uhpc) As A Repair Material Durability Performance, Rebar Coating, And Bond Characterization, Haitham Hussein

All Dissertations

Ultra-High Performance Concrete can be a very good material for use in repair works. The ability of chloride ions to pass through repaired concrete layers is suppressed if an impermeable concrete like UHPC is used. However, thickness of the UHPC layer and the orientation of the repair layer relative to the direction of chloride ingress may influence its effectiveness. This study is an attempt to evaluate the effect of varying thicknesses and cross sections areas of UHPC over a precast concrete and the direction of the UHPC layers relative to the direction of chloride ion movement on the resistance offered …

Computational Characterization Of Nonwoven Fibrous Materials: Transport And Wetting Properties, Fang Wang

All Dissertations

Nonwoven fibrous materials represent a platform of flexible material substrates. Nonwovens are widely used in the production of napkins, paper, filters, wound covers and face masks. In addition, for many applications, nonwoven materials interact with fluids. For example, in filtration applications, nonwoven materials are used to clean fluids containing solid particles or emulsified droplets. The filtration performance is affected not only by the geometrical arrangement of fibers in non-woven materials but also wettability of fibers. Understanding the transport properties of nonwoven materials and interactions between the dispersed droplets and solid substrate is crucial for the design and optimization of filter …

Radioluminescence Based Biochemical Sensing And Imaging Strategies To Measure Local Drug Release And Ph, Gretchen B. Schober

All Dissertations

In this dissertation we describe methods for measuring infection relevant biochemical analytes using radioluminescent and ultrasound luminescent materials. Films and nanoparticles fabricated with europium doped gadolinium oxysulfide (Gd₂O₂S:Eu³⁺) are used to quantitatively measure radiolabeled pharmaceutical concentration, specifically tritium labeled vancomycin (³H-vancomycin). Europium and dysprosium doped strontium aluminate is used to fabricate an ultrasound modulated, pH sensing film. These methods are indicated for theranostic evaluation of implant associated infection. Bacterial biofilms are inherently resistant to traditional antibiotic treatment and can coat biomedical implants. These biofilm related infections are difficult or impossible to eradicate …

Development Of A Reverse Engineered, Parameterized, And Structurally Validated Computational Model To Identify Design Parameters That Influence American Football Faceguard Performance, William Ferriell

All Dissertations

Traumatic brain injury (TBI) continues to have the greatest incidence among athletes participating in American football. The headgear design research community has focused on developing accurate computational and experimental analysis techniques to better assess the ability of headgear technology to attenuate impacts and protect athletes from TBI. Despite efforts to innovate the headgear system, minimal progress has been made to innovate the faceguard. Although the faceguard is not the primary component of the headgear system that contributes to impact attenuation, faceguard performance metrics, such as weight, structural stiffness, and visual field occlusions, have been linked to athlete safety. To improve …

Design And Operation Of A Microwave Flow Cytometer For Single Cell Detection And Identification, Jeffrey A. Osterberg

All Dissertations

Microwave dielectric sensing has become a popular technique in biological cell sensing for its potential in online, label-free, and real-time sensing. At microwave frequencies probing signals are sensitive to intracellular properties since they are able to penetrate cell membranes, making microwave flow cytometry a promising technology for label-free biosensing. In this dissertation a microwave flow cytometer is designed and used to measure single biological cells and micro particles. A radio frequency (RF)/microwave interferometer serves as the measurement system for its high sensitivity and tunability and we show that a two-stage interferometer can achieve up to 20 times higher sensitivity than …

Rewilding With Ar And Vr: Facilitating Care With Photography In Physically Immersive Apps, Kailan Sindelar

All Dissertations

In this dissertation I analyze two AR apps from Internet of Elephants, Safari Central and Wildeverse, and one VR app from National Geographic, National Geographic: Explore VR. These three apps use photography as the central tool for engagement, attempt to educate users, and prompt them to care about wildlife and wilderness. However, the ethical consideration of design has largely ignored representations of the environment, especially as it may intersect with facilitating care for wilderness and wildlife that is experiencing the effects of habitat destruction and environmental degradation. This project begins developing a critical discussion of how wilderness and …

Revealing The Role Of Electrostatics In Molecular Recognition, Ion Binding And Ph-Dependent Phenomena, Mihiri Hewa Bosthanthirige

All Dissertations

In this dissertation, we study the role of electrostatics in molecular recognition, ion binding and pH-dependent phenomena. In this work that includes three different research projects, the Poisson-Boltzmann (PB) model is used to describe the biological system and Delphi (which is a popular tool for solving the PB equation (PBE)) to study the electrostatics of biomolecular systems.

Chapter two aims to investigate the role of electrostatic forces in molecular recognition. We calculated electrostatic forces between binding partners separated at various distances. To accomplish this goal, we developed a method to find an appropriate direction to move one chain of protein …

Mitral Valve Tissue Engineering - A Dynamic Model For Investigating The Mechanism Of Valvular Pathology, Collin Owens

All Dissertations

Heart valve disease affects an average of 2.5% of the population in the United States. The mitral valve (MV) is the most complex of the heart’s four valves and is most associated with the disease by exhibiting altered extracellular matrix (ECM) which translates into stenosis or regurgitation. These diseases are typically degenerative in nature and can be accelerated by risk factors such as diabetes and hypertension. With diabetes and hypertension affecting 425 million and 1.39 billion people worldwide, further investigation into these risk factors is warranted. This study aims to develop and test an in vitro model of MV disease. …

Selected Female High School Athletic Directors Describe Their Career Trajectories, Mary Helen Coleman Martin

All Dissertations

ABSTRACT

There is an underrepresentation of women in the formal role of athletic directors in the interscholastic sport setting. Additionally, little is known about the lack of female representation at the interscholastic level. Utilizing phenomenological methodology, this study explored the career paths and lived experiences of interscholastic athletic directors. Using purposeful sampling, 13 female interscholastic athletic directors took part in semi-structured interviews. Emerging ideas from the lens of current female interscholastic athletic directors offer implications about direction and information needed to assist inspiring young females as they ascend the career ladder in becoming interscholastic athletic directors.

Patterns Of Evolutionary Conservation And Divergence In The Short-Term Hyposalinity Stress Response Of A Euryhaline Diatom, Skeletonema Marinoi, Kathryn Judy

Graduate Theses and Dissertations

Survival under fluctuating environmental conditions, such as those increasing in frequency and magnitude under environmental change, requires a successful response to stress. Interspecific differences in stress responses may result in differential survival of species, even within a lineage. Diatoms may constitute one such lineage, as salinity tolerance among extant species is diverse, and the observation of frequent historic habitat transitions between marine and freshwater environments indicates that diatoms successfully mitigated (low) salinity stress in the past, followed by adaptation and diversification over evolutionary time scales. To understand to what extent the diatom hypoosmotic stress response consists of conserved and variable …

Physiognomic Artificial Intelligence, Luke Stark, Jevan Hutson

Articles

The reanimation of the pseudosciences of physiognomy and phrenology at scale through computer vision and machine learning is a matter of urgent concern. This Article—which contributes to critical data studies, consumer protection law, biometric privacy law, and antidiscrimination law—endeavors to conceptualize and problematize physiognomic artificial intelligence (“AI”) and offer policy recommendations for state and federal lawmakers to forestall its proliferation.

Physiognomic AI, as this Article contends, is the practice of using computer software and related systems to infer or create hierarchies of an individual’s body composition, protected class status, perceived character, capabilities, and future social outcomes based on their physical …

Playing With The Music: Ecologies Of Attention And Understanding In The Classical Music Education Project Of Sesame Street Or The Bird, The Worm, And The Mushroom: Three Stories Of Listening, Eden Attar

Arts & Sciences Graduate Student Theses and Dissertations

This is a paper about the ecologies of attention and understanding evident in and emergent from the presentation of classical music on the classic children’s television program Sesame Street. The paper is written in two chapters. The first is an analysis of context, attention, and education on the program, framed through the analogy of bird-watching. I argue that the classical music education which is presented on the program deviates from the humanitarian norm of “uplift” and absolute aesthetics—the bird’s-eye view— and instead presents an understanding of music which resonates with ideas of “listening with”—the view of the bird watcher, …

The Intricate Interplay Between Cancer Stem Cells And Cell-Of-Origin Of Cancer: Implications For Therapeutic Strategies, Luis Alberto Vega, Misu A Sanson, María Belén Cubria, Shrijana Regmi, Brittany J Shah, Samuel A Shelburne, Anthony R Flores

Faculty, Staff and Student Publications

Antimicrobial resistance-encoding mobile genetic elements (MGEs) may contribute to the disease potential of bacterial pathogens. We previously described the association of Group A Streptococcus (GAS) derived from invasive disease with increasingly frequent antimicrobial resistance (AMR). We hypothesized that a 65-kb AMR-encoding MGE (ICESpyM92), highly conserved among closely related emergent invasive emm92 GAS, contributes to GAS disease potential. Here, we provide evidence that a combination of ICESpyM92- and core genome-dependent differential gene expression (DGE) contributes to invasive disease phenotypes of emergent emm92 GAS. Using isogenic ICESpyM92 mutants generated in distinct emm92 genomic backgrounds, we determined the presence of ICESpyM92 enhances GAS …

Pulmonary hypertension (PH) comprises a diverse group of disorders that share a common pathway of pulmonary vascular remodeling leading to right ventricular failure. Development of anti-remodeling strategies is an emerging frontier in PH therapeutics that requires a greater understanding of the interactions between vascular wall cells and their extracellular matrices. The ubiquitous matrix glycan, hyaluronan (HA), is markedly elevated in lungs from patients and experimental models with PH. Herein, we identified HA synthase-2 (HAS2) in the pulmonary artery smooth muscle cell (PASMC) layer as a predominant locus of HA dysregulation. HA upregulation involves depletion of NUDT21, a master regulator of …

The Experiences Of Sexually Abused Women With Disabilities Who Consulted Services In Zimbabwe: The Intersection Of Disability, Gender, And Poverty, Tafadzwa Oswell Rugoho, Michael Ashley Stein, Pamela Wright, Jacqueline E. W. Broerse

Dignity: A Journal of Analysis of Exploitation and Violence

Women have experienced sexual abuse, and very few of them report to the police or seek other services, such as medical attention. This study aims to gain insight into the barriers women with disabilities face when accessing police, health, and counseling services after experiencing sexual abuse. Barriers such as long distances, physical barriers at service sites, communication barriers, gender issues, lack of confidence in the service providers, and an overall lack of resources were reported. In a study undertaken in Zimbabwe, women with disabilities encountered intersecting barriers such as the intersection of disability, and gender, poverty, unemployment, and low levels …
