Principals’ Perceptions Of School Sponsored Field Trips, Melissa Suzanne Giannantonio

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this phenomenological study is to explore the views, attitudes, and ideas that school principals have on school-sponsored field trips. As society continues to change it is increasingly necessary to contemplate the growing significance of field trip facilities’ educational roles and garner “information about the audiences they serve” (Anderson et al., 2015, p. vii). Additionally, the past decade has seen a decline in the number of field trips taken by schools, and in 2020, field trips came to a complete halt due to COVID-19 (Center for Disease Control (CDC), 2020; Mathews, 2014; Mehta, 2008; Plummer, 2014; Reeves & …

Faculty, Staff and Student Publications

With the exponential growth in investment attention to brain health-solutions spanning brain wellness to mental health to neurological disorders-tech giants, payers, and biotechnology companies have been making forays into this field to identify technology solutions and pharmaceutical amplifiers. So far, their investments have had mixed results. The concept of open innovation (OI) was first coined by Henry Chesbrough to describe the paradigm by which enterprises allow free flow of ideas, products, and services from the outside to the inside and vice versa in order to remain competitive, particularly in rapidly evolving fields where there is abundant, relevant knowledge outside the …

Quantitative Techniques For Classifying Mouldings: An Exploration Of Logistic Regression Within Architectural Investigations, Chase Pilcher

All Theses

Since the passing of the National Historic Preservation Act in 1966, the realm of architectural history has evolved, becoming more interdisciplinary. There was a shift in focus from looking at architecture from a fine art point of view to looking at it through a social lens. The new social perspective approach focused not only on the buildings but also on the people that inhabited or constructed the space. Approaching architectural investigations in this manner has allowed for a deeper understanding of the influences that shaped the built environment. Advancements in technology have also aided in furthering our overall comprehension of …

Physical Accessibility And Historic Preservation In Historic House Museums Of The Southeast, Abby Milonas

All Theses

Museums are a public good, as they provide educational recreation and preserve cultural history, and so it is crucial that they are physically accessible to as many visitors as possible. The aim of this study was to understand what architectural features of historic house museums are the least accessible and what has been done to ameliorate these challenges. The survey used in the study was developed using the guidelines for making historic buildings accessible as described in the Americans with Disabilities Act and the Uniform Federal Accessibility Standards. It was distributed by email to representatives of 220 historic sites, of …

Bringing Vanished Landscapes To The Surface: A Multi-Tool Approach To Unearthing Charleston's Walled City, Alexis Allen

All Theses

The early 18^th century historic fortification system that surrounded the urban town of Charleston has been a focus of excavations and historical research within the past two decades. However, while the outline of early Charleston’s walled city is hypothesized through the analysis of historic maps and plats, very few fortification locations have been visually confirmed. In order to determine their accuracy, this thesis georeferenced eleven historic maps and four plats to the modern landscape. As a result, possible locations of Charleston’s walled city were predicted. These were surveyed as test sites and remote sensing methods were employed that helped …

“Provisioned, Produced, Procured,” And Purchased?: A Macrobotanical Study Of Enslaved Individuals’ Economic Engagement In The Shenandoah Valley, Linda A. Seminario

Graduate Masters Theses

This research investigates enslaved peoples’ economic engagement in the Shenandoah Valley during the first half of the 19th century. In 2017, archaeologists excavated two features at the Belle Grove enslaved quarters in Middletown, Virginia— a root cellar and subfloor pit that were filled in when a log cabin burned down. The preservation of the macrobotanicals has allowed for an in-depth analysis of the plants with which enslaved individuals engaged and the relationship between plant acquisition and enslaved people’s regional formal economic involvement at a 19th-century plantation in the Shenandoah Valley of Virginia. These data sets have also allowed for an …

Assessing Sexual Minority Women’S Barriers And Facilitators To Seeking And Accessing Mental And Physical Healthcare: A Mixed Methods Study, Charlotte A. Dawson

Psychology Theses & Dissertations

Sexual minority women (SMW) experience greater mental and physical health concerns when compared to heterosexual women. Three key areas of health SMW report these disparities are: mental health, binge eating/body size, and sexual and reproductive health. SMW also report difficulties accessing healthcare in these three areas. An exploratory sequential mixed methods design was utilized to assess barriers and facilitators to healthcare access for young SMW. Study 1 included 20 semi-structured interviews with SMW, resulting in themes of barriers and facilitators identified by participants. These themes were converted into scale items. In Study 2, an expert panel of mental and physical …

Vaccination Intention And Uptake Within The Black Community In Appalachia, Jamey T. Brumbaugh, Kalo C. Sokoto, Casey D. Wright, Sarah E. Francis, Jaliyah Hubbard, Linda Alexander, Daniel W. Mcneil

School of Dentistry Faculty Research and Publications

Objective:

Black communities have disproportionately experienced adverse health effects from the COVID-19 pandemic while simultaneously having less vaccination access and decreased vaccine utilization. As such, predictors of vaccination uptake within Black communities are a public health imperative. Black Americans from socio-geographic regions associated with health inequities (e.g., Appalachia), including vaccination disparities, represent an intersection of racial, economic, and ethnic social identities. To better understand the preventive health needs of Black communities in Appalachia and elsewhere, this study examined psychosocial predictors of vaccination intention or behavior.

Method:

Adults (n = 336) identifying as Black or African American from West …

The Role Of Justice In Colombia’S Renewable Energy Transition: Wind Energy Development In Wayúu Territory, Adriana P. Fajardo Mazorra

Dartmouth College Master’s Theses

Amidst the defining issue of our time – climate change – the world faces an imperative to shift from fossil fuels to renewable energy, aligning with the 2015 Paris Agreement goals. This global focus on low-carbon energy infrastructure has brought forth local socio-environmental conflicts, and at the heart of this transition lies La Guajira, a peninsula in northern Colombia, home to the indigenous Wayúu people and abundant wind energy resources. This research delves into the critical role of energy justice as large-scale wind energy projects expand in La Guajira. By examining the struggles faced by the Wayúu people provoked by …

Price Volatility, Human Rights, And Decarbonization Challenges In Global Solar Supply Chains, Dustin Mulvaney, Morgan Bazilian

Faculty Research, Scholarly, and Creative Activity

Abstract From 2020 through 2022 the solar industry experienced supply chain disruptions that caused price increases and trade restrictions, causing project delays and cancelations. News reports resurfaced allegations of human rights abuses in Xinjiang, China, where a significant share of the industry supply chain is concentrated, which raised new policy and ethical dilemmas about materials sourcing for governments and buyers, and revealed a vulnerable supply chain. Fixing the weak links in solar supply chain will require multiple interventions that diversify the geography of manufacturing and lead some countries to re-shore production. Increased attention to sustainability and low carbon manufacturing initiatives …

Cultural Mechanism Of Mothers' Perceptions Of Youth Psychopathology, Yen-Ling Chen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Cross-cultural research systematically identifies variations in cultural practices, meanings, and responses across different cultural groups. For example, psychiatric symptoms vary in their salience and degree to which they are reported across cultures. Cultural differences in causal attributions likely lead to differences in an individual’s help-seeking intention. However, there are limitations in previous cross-cultural studies about perceptions of psychopathology, including not measuring impairment level and parental distress, as well as the problematic use of categorical variables as predictors. To overcome limitations in previous work, the current project examined the cultural mechanism of mothers’ perceptions of externalizing and internalizing psychopathology in youth. …

Beyond The North–South Divide: Litigation's Role In Resolving Climate Change Loss And Damage Claims, Maria Antonia Tigre, Margaretha Wewerinke-Singh

Sabin Center for Climate Change Law

Within the international climate regime, legal aspects surrounding loss and damage (L&D) are contentious topics, implicating liability, compensation and notions of vulnerability. The attribution of responsibility and the pursuit of redress for L&D present intricate legal and governance challenges. The ongoing debates under the United Nations Framework Convention on Climate Change are characterized by a pronounced North–South divide and have done little to provide tangible support to those most affected by L&D. This apparent neglect has prompted exploration of alternative avenues for climate harm redress. The burgeoning field of litigation for liability and compensation of climate harm holds potential significance …

Abolition’S Informal Gatekeepers: The Role Of County Courts In The Making Of Pennsylvania’S ‘Free’ Border, Amanda Mcgee

Graduate Theses and Dissertations

Because Pennsylvania was the first state to implement legislation that slowly ended slavery within the state, contests over freedom and the enforcement of where it began and ended became an essential element of Pennsylvania’s border-making policies in the late eighteenth and early nineteenth century. The struggle over the territorial extent (by which I mean legal and geographical) of Pennsylvania abolition between enslavers intent on retaining their human chattel by any means necessary and enslaved men and women intent on asserting their freedom once they touched Pennsylvania “free soil” in turn, served to solidify the geopolitical boundary of the state in …

Holocaust Education In Arkansas: An Exploration Of Policy Process And Implementation, Toby Klein

Graduate Theses and Dissertations

The Holocaust was the attempted extermination of the Jewish people--a fact previously considered to be common knowledge. However, recent national surveys find that Arkansas students have the lowest levels of knowledge of the Holocaust in the United States. A recent law mandated the teaching of the Holocaust for 5-12th grade public school students in Arkansas, however, little is known about the policy process and implementation of such a mandate. Given the magnitude of the gaps in the literature on this topic, this dissertation uses a three article format to address specific gaps and make specific contributions to the literature by …

Acting Locally: Vegetable Gardening In Southern Illinois, Aimee L. Trojnar

Dissertations

This dissertation explores the everyday practice of home and community vegetable gardening in a small southern Illinois city. The project engages with questions of how diverse elements of practice interact over time in the development of both gardens and gardeners, dwelling particularly on how the material agency of nonhumans contributes to what emerges. Combining a broad investigation of societal influences and constraints involved in gardening practices with a granular focus on material interactions in the garden, I consider the kinds of relationships individuals forge with the nonhuman environment in a modern, Western context and how they do so. Understanding such …

The Aesthetics Of News: Narrative Construction And Media Illiteracy In Contemporary India, Shashidhar Nanjundaiah

Dissertations

Amidst the public’s declining trust in news, media prosumers—that is, media consumers who have also become producers of mediated texts—are not equipped with any credible alternative mechanism to better understand the world around them. Prior academic studies of news and its delivery have not adequately explored the ideological framework we need to confront this frightening situation. This dissertation does so. I problematize the narration of news as an aesthetic process. Such mass-mediated narration stitches together our world in ideological ways. A tidal flow of stories highlights and obscures selected truths in a frenzy of “new” news cycles, the frequency of …

Englacial Drainage Drives Positive Feedback Depression Growth On The Debris-Covered Ngozumpa Glacier, Nepal, R. M. Strickland, M. D. Covington, J. D. Gulley, R. B. Kayastha, J. M. Blackstock

Geosciences Faculty Publications and Presentations

The development of hummocky topography is a poorly understood aspect of down-wasting on debris-covered glaciers that is often attributed to variable debris thickness. Thousands of enclosed depressions pit the hummocky topography. To better understand depression growth, we examined the size distribution and geometry of depressions on the Ngozumpa Glacier, in the Everest Region of Nepal. The depressions exhibited a power-law size distribution, fractal perimeters, and power-law depth-area scaling, which suggest positive feedback growth. With a simple model, we showed that positive feedback growth produces similar power-law size distributions. Based on these findings, we propose a “sinkhole” hypothesis for the development …

Holocene Variations In The Asian Summer And Winter Monsoons Reconstructed From Extensive Lacustrine Sediments In The Mu Us Desert, Northern China, Xiaohao Wen, Matt W. Telfer, Baosheng Li, W Wang, Tim Daley, C Wang, Mengyuan Tian, Mingkun Qiu

School of Geography, Earth and Environmental Sciences

The Salawusu River Valley cuts through the Mu Us Desert in north central China, and lies at the interface of the East Asian Summer and Winter Monsoonal regions. Exposed at numerous locations in the valley side are extensive late Quaternary deposits, consisting of interbedded aeolian sands, fluvio-lacustrine units and palaeosols. Due to the importance of the location in potentially elucidating both summer and winter monsoonal regimes, and the quality of the sedimentary record, the region has a rich history of study, and yet even within the Holocene sequence, many conflicting interpretations have arisen based on studies on different sections. This …

Development Of The Navigator: A Lagrangian Smart Sensing System To Characterize Aquatic Ecosystems., Aashish Sanjay Khandelwal

Civil Engineering ETDs

Most freshwater aquatic studies rely on Eulerian monitoring, i.e., water quality and quantity are monitored using grab samples or semi-continuous sensors deployed at fixed cross-sections. While Eulerian monitoring is practical, it provides a limited understanding of spatial and temporal heterogeneity and their effects on environmental processes. This dissertation summarizes the design and application of The Navigator, an alternative Lagrangian monitoring system that offers cost-effective solutions for in-situ, real-time data collection in lotic and lentic freshwater ecosystems such as streams, rivers, ponds, and reservoirs. The Navigator features a suite of methods – an autonomous surface vehicle (ASV) with GPS and LTE …

An Investigation Of Freshwater Turtle Ecology Using Stable Isotopes, Jonathan Duran

Biology ETDs

In 2022 I investigated niche partitioning among native and invasive freshwater turtles across three sites in the Middle Rio Grande using bulk stable isotope analysis. I found high degrees of niche partitioning at sites in which Red-eared sliders (Trachemys scripta) have yet to establish. However, at sites in which red-eared sliders are now the most abundant species they overlapped greatly in isotopic niche with all native turtles, in particular the painted turtle (Chrysemys picta). Using these same techniques, I then examined the trophic interactions between red-eared sliders and their acanthocephalan parasites. My results suggest that acanthocephalans …

Post-Fire Plant Community Response In Subalpine Mixed Conifer Forest, Sasha Escamilla

Biology ETDs

Increased wildfire activity may lead to significant shifts in vegetation dynamics in high elevation mixed conifer forests. These changes raise concerns about the resilience of forests following wildfire, prompting the need for a deeper understanding of post-fire plant community response. We analyzed up to 11 years of post-fire vegetation data from Valles Caldera National Preserve in northern New Mexico to determine how burned vegetation sites were recovering following high severity wildfire, and whether or not plant communities were transitioning to montane grassland. We found burned understory herbaceous communities were not transitioning into distinctive montane grasslands and were instead recovering to …

Digitally Rural: Identifying How Technological Inequity Impacts Rural Students In First-Year Writing Courses, Jo Anna M. Nevada

English Language and Literature ETDs

To teach composition in this era means to engage students with technology; it is all but an unspoken requirement at the majority of universities. This dissertation theorizes, however, that the imbricated use of technology in first-year writing (FYW) classrooms places rural students at an inherent disadvantage, with issues of inadequate technological proficiency and inconsistent access causing a substantial learning disparity between this student population and their urban peers. Through mixed-methods data analysis of student survey responses and final FYW course portfolios, this study reveals that the expectation of technological access and presumption of digital literacy is detrimental to rural student …

Testing The Niche Center Hypothesis In The Fossil Record Of Atlantic Bivalves, Rhiannon Z. Nolan

Earth and Planetary Sciences ETDs

Paleoecological analyses of six shallow marine bivalves were conducted to test the Abundant Center Hypothesis using data from the fossil record of the Pleistocene through modern day. This hypothesis predicts the highest abundance of a species is at the center of the geographic or environmental range, decreasing toward the edges. In geographic space, distances to a centerline within a geographic range were variably correlated with population abundances, and some species displayed a sharp drop-off in abundance as distance increased. In environmental space, bivalve species showed moderate correlations between abundance and centrality when measured using cumulative data across the last 2.8 …

Projecting Vegetation Condition And Fire Risk In Southern California, Westin K. Guthrie

Geography ETDs

In the western US, relationships between fire, vegetation, climate, and urban areas are dynamic and evolving. This work used a forest landscape model, LANDIS-II, informed by future climate scenarios and projections of urban expansion to understand wildfire interactions within projected Wildland Urban Interface (WUI) areas. This simulation showed that in both 2050 and 2100 +93% of the WUI in southern California experienced fire. Future work needs to be done in parametrizing forest biomass to ensure the validity of projections. Additionally, increasing each climate scenario model's replicates will create more accurate projections.

Slavery And Architecture Across The Mediterranean, John Behnken

History ETDs

Enslaved people as architectural material, found in the cultural examples of the Great Mosque of Cordoba and the Hagia Sophia, provide a lens from which scholars can re-envision the historical narrative. The scholarship surrounding the development and transition of the Great Mosque of Cordoba from a mosque to a church, elicits new research into what medieval people thought about race, race-making, and cultural ownership. The conceptions of race are evident through the medieval paradigms of enslavement. Who could and could not become enslaved establish social, cultural, and phenotypic classifications which in turn become race. The work of scholars such as …

Ayllus And Haciendas: Social Reproduction Of Community And Reciprocity In Nineteenth Century Ecuador, Laura Powell

History ETDs

This dissertation argues that indigenous peons of nineteenth-century Ecuador maintained ayllu practices of community and reciprocity through the reconfiguration of kinships networks and the reinterpretation of reciprocity within the context of the hacienda system. This argument challenges prevalent beliefs that indigenous networks of kinship and reciprocity largely dissolved with the rise of the hacienda system and the oppressive exploitation of the institution of debt peonage known as concertaje. However, a close reading of the hacienda records shows that, first, indigenous peons used their ability to accrue debt in order to build and maintain communities of both real and fictive kinship …
