A Phenomenological Study: The Lived Experience Of Jamaican Immigrant Teachers Practicing In Northeastern North Carolina, Dianne Campbell-Barton

Doctor of Education Dissertations

Public school districts across the United States (U.S.) have struggled with the hemorrhaging of teachers for many years and have become creative in staffing classrooms, which includes hiring overseas teachers. This qualitative phenomenological study explored the lived experiences of Jamaican exchange visitor program (EVP) teachers practicing in northeastern North Carolina K-12 public and charter schools. An amalgamation of Milton Gordon’s (1964) assimilation and John Berry’s (1977) acculturation theories guided the research. Semi-structured interviews were used to capture and examine the Jamaican EVP teachers' stories of success, challenges, and resilience. The study capitalizes on the power of Jamaican EVP teachers’ stories …

Plant Nutrient Contents And Spatial Distribution Patterns Of Toxic Element Concentrations In Mine Site Soils, Gülşen Tozsi̇n, Taşkin Öztaş

Turkish Journal of Agriculture and Forestry

Open-pit coal mining causes land and soil degradation and negatively affects soil properties. It is of great importance to determine variabilities in soil properties of the abandoned area after the mine is closed and to bring it back to nature by implementing appropriate rehabilitation programs. The aim of this study was to evaluate plant nutrient availability and toxic element pollution in an abandoned coal mine site. The results indicated that the amounts of plant-available P and K are quite low (<90 kg P₂O₅ ha^-1) and low to moderate (<170 kg K₂O ha^-1), respectively. The concentrations …

Between Disruption And Legitimation Of Development: A Critical Perspective On The Inspection Panel And A Call For More Radical Thinking Within The Accountability Community, Dustin Schäfer

Perspectives

The essay explores the Inspection Panel’s (the Panel) conflicting role of providing accountability for negatively affected people while facing political limitations. The Panel has proven its potential to disrupt harmful development practices. However, by reproducing “dev-speak” it also continuously contributes to legitimizing the same assumptions of “how to do development”, and thus to the continuation of harmful development practices. This ambivalent effect is inherent to the Panel because of its politically inhibited and depoliticized (i.e. technocratic) environment. To overcome this long-lasting and structural condition will require critical examination of the concept of development and the role it plays in …

Sagebrush Steppe Songbird Conservation: Inferences Using Remote Sensing Data And A Novel Reproduction Model, Kaitlyn Marie Reintsma

Graduate Student Theses, Dissertations, & Professional Papers

Anthropogenic land cover change continues to degrade and fragment wildlife habitats, threatening biodiversity at local, regional, and global scales. Songbird populations are sensitive to broad habitat changes and therefore can be used to assess and prioritize habitat for biodiversity. For example, biodiversity losses in the arid grass and sagebrush of western North America (Artemisia spp.; hereafter “sagebrush steppe”) are reflected in the rapid decline of songbird populations. However, the influence of the principal land use, livestock grazing, on songbird populations, and by inference biodiversity, is unclear. In this dissertation, I investigated sagebrush steppe songbird conservation in a grazed landscape by …

This excerpt from the novel Water Lake takes place at an undisclosed time in an undisclosed American location called Water Town. It primarily follows Jason and Holly, who are employees at Water Hardware and lifelong residents of the insular, religious, isolated town. Water Town is in constant industrial and environmental decay and hosts many mysterious natural and social phenomena such as an unusual amount of animal deaths, a gender ratio skewed disproportionately towards men, and a single seal in a local body of water hundreds of miles from the nearest ocean. During an episode of impulsivity induced by neurological trauma, …

Evaluating The Use Of Environmental Tracers To Reduce Conceptual Model Uncertainty Of Hydrogeologic Models, Andrew Nordberg, Jon Graham, W. Payton Gardner

Graduate Student Theses, Dissertations, & Professional Papers

Environmental tracer concentrations for CFC12, SF6, and tritium are used in groundwater simulations to assess the ability of these tracers to reduce conceptual model uncertainty due to uncertainty of a site’s geologic and recharge characterization. The resulting groundwater simulations are characterized by site-specific hydrologic and geologic data, and with coordination from a field team with years of knowledge about the site. First-order (conceptual) uncertainty is directly addressed by using a stochastic modeling approach for spatial variability of the proposed subsurface configurations. Simulations of environmental tracer concentrations and water levels are used to assess six alternate conceptual models that are based …

Beulahland: A Novel, Emily Ann Marie Nelson

Graduate Student Theses, Dissertations, & Professional Papers

Beulahland follows Esther and Beulah Baxter, a pair of orphaned sisters traveling across the American west with their evangelist uncle in 1994. Raised on the seedy motivational speaking circuit of small towns and youth groups, Esther is determined to free Beulah from this nomadic way of life under from the neglectful care of their uncle August, a fame-chasing bodybuilder who wants to bring the world to God through his demonstrations of physical strength. This plan is put on hold when Beulah falls ill during a routine performance in the wildfire-wracked town of Orchard, Washington, and almost dies; her near-death experience …

Blood And Oil: How Vampiric Literature Bolsters Big Oil’S Power, Sarah Marie Demond

Graduate Student Theses, Dissertations, & Professional Papers

This thesis examines the relationship between blood and oil, that is, the multitude of ways in which the petromodernity industries harvests and threatens vitality. The introduction of this thesis is concerned tracking how petromodernity is a byproduct, offspring, or extension of colonialism. In this way, petromodernity can be thought about as “petro-colonialism.” Ursula K. LeGuin’s “Carrier Bag Theory of Fiction” informs the argument that the way thay petro-colonialism came to be and also maintains itself is by utilizing the “killer story.” This thesis also employs autorheoretical techniques informed by Lauren Fournier to show how petro-colonialism or “oiliness” sticks to its …

Variation In Body Composition In Deer Mice: The Biogeography And Ecophysiology Of Energy Allocation, Cole Joseph Wolf

Graduate Student Theses, Dissertations, & Professional Papers

Body composition, the percent of lean and fat mass, is a snapshot of an individual’s energetic state at a moment in time. Wild organisms should allocate energy to optimize fitness, so tracking changes in body composition provides a window into how priorities may shift throughout the year or across environments. While seasonal variation in body composition is wellcharacterized in systems such migrating birds (Scott et al. 1994) and hibernating mammals (Hellgren 1998), much less is known about how this trait varies across species ranges and thus how organisms modify their body composition and to meet local environmental challenges. For my …

An Examination Of The Food System, Foodscape, Dietary Patterns, And Accolated Health Outcomes Of Salish People Within The Confederated Salish And Kootenai Nation, Joshua William Brown

Graduate Student Theses, Dissertations, & Professional Papers

Often an individualistic, consumerist strategy is promoted as the solution to decrease the growing prevalence of diet-related diseases. Unfortunately, this logic is ahistorical and apolitical while privileging pathological individualism, capitalistic consumerism, and prevalent diets within the United States. This reasoning fails to recognize diet construction across time by ideologies, policies, and practices. Such an outlook misses the reality that many people cannot escape the grip of the modern, pervasive, ultra-processed food system.

Several Native American populations find themselves plagued with high rates of diet-related diseases. Standard mantra shoulders these communities with their plight, often framing the discourse as personal responsibility …

Supervised Cancer Rehabilitation: Applications For Utilizing Existing Cardiopulmonary Rehabilitation Facilities For Cancer Patients And Survivors, Nancy A. Condit

Graduate Student Theses, Dissertations, & Professional Papers

Currently, the NIH reports there are approximately 18 million Americans with a history of cancer. Cancer statistics are projected to rise to 22.1 million by 2030. In addition to cancer, cardiovascular diseases are globally the leading causes of mortality and morbidity. The body of research in this area clearly demonstrates that greater amounts of physical activity correspond with a lower risk of cancer recurrence and all-cause mortality, including cardiovascular disease (CVD). Exercise rehabilitation success in cancer patients, both during and after treatment, is limited by several barriers, including the lack of facilities, trained personnel and financial resources. In response to …

Negotiating The Sacred: Understanding Impacts To Iks And Itek From Use Of Remote Sensing And Gis Technologies Within Tribal Landscapes, Renelda R. Freeman

Graduate Student Theses, Dissertations, & Professional Papers

How we see the world and ourselves in relation to it is largely achieved by the lens we are looking through and associated experiences within this relationship. This is additionally true when considering the acknowledged fact that Indigenous Knowledges are derived from natural and cultural sources and these assist in constituting the cultural identities of those Peoples associated with these sources. Presently there is a hunger for access and use of Indigenous Knowledges (IK) as never before seen in public ways, through a national Call for collaborative means to apply these knowledges to such as the issues we globally face …

Beaver Dam Analogs (Bdas) Alter Carbon Pools, Fluxes, And Concentrations Of Intermountain Headwater Streams, Hilary Schultz

Graduate Student Theses, Dissertations, & Professional Papers

Beaver dam analogs (BDAs) have emerged as a climate adaptation and restoration strategy for water resource management in the drought-prone Western U.S., yet the focus has been on their influence on water quantity, overlooking effects on broader ecological components. By increasing water residence time and facilitating sediment retention, BDAs have the potential to influence carbon pools, fluxes, and concentrations. To examine the influence of BDAs on instream and riparian organic C and trace gases, we studied three intermountain headwater streams restored with BDAs two years after restoration during the summer of 2021. We found that there were subtle differences in …

Electric Momentum: Dynamics Of Transportation Electrification And Stories From The Road, Amelia Liberatore, Amelia R G Liberatore

Graduate Student Theses, Dissertations, & Professional Papers

The climate is undeniably changing. The Intergovernmental Panel on Climate Change (IPCC) published yet another report this year outlining how extreme weather, brought on by our use of Earth's resources, causes loss of nature and human life around the world. The summer of 2023 broke records for high ocean temperatures and melting polar ice, and abnormally potent floods and fires touched all corners of the Earth. Industrial production of goods, and the personal choices that purchase them, are responsible for massive amounts of greenhouse gases (GHG), including carbon dioxide and methane. GHG emissions thicken the Earth's atmosphere and continue the …

Synthesis And Characterization Of Novel Biomaterials: The Use Of Hyaluronan For Otologic Applications And Silk Fibroin For Sensing Applications, Elizabeth Marie Arrigali

Graduate Student Theses, Dissertations, & Professional Papers

We have developed four projects using biomaterials including hyaluronan (HA) and silk fibroin (SF) for biomedical applications. First, we investigated an HA-antioxidant conjugate for topical application in sensorineural hearing loss (SNHL). Drug delivery to the ear is very difficult. Systemic approaches usually result in low concentration to the ear and topical approaches are difficult with the two anatomical membranes of the ear: the tympanic membrane (TM) and the round window membrane (RWM). We have chosen an HA-based drug conjugate as HA has been shown to permeate through anatomical membranes like the skin. Our hypothesis was that an antioxidant like DMethionine …

The Politics Of Abundance: American Philanthropy And The Political Economy Of Food In The Twentieth Century, Elizabeth Berit Barrs

Graduate Student Theses, Dissertations, & Professional Papers

“The Politics of Abundance: American Philanthropy and the Political Economy of Food in the Twentieth Century” uses food aid as a lens to understand how philanthropy became a significant new force in the twentieth-century political economy, both in the US and in the projection of American power abroad. I argue that US-based international food philanthropy joined with the state and the full breadth of the American food industry to structure the political economy of food in the twentieth century and to export it globally, impacting how much of the world produces and consumes food. Voluntary agencies and foundations provided a …

High-Frequency Observations Of Riverine Inorganic Carbon Variability Using In Situ Autonomous Sensors, Qipei Shangguan

Graduate Student Theses, Dissertations, & Professional Papers

Rivers and streams actively metabolize, emit, transport and store carbon of various forms received from terrestrial environments. Our current understanding of how rivers and streams contribute to the global carbon cycle remains limited, however, in part due to high temporal variability and complexity of inorganic carbon chemistry. In situ autonomous chemical sensors provide powerful tools to observe changes in rivers and streams and enable development of CO2-specific models to quantify riverine processes. In many aspects, our ability to utilize high-frequency sensor measurements remains limited.

This dissertation aims to improve our understanding of inorganic carbon cycling through sensor technology and numerical …

Conflict And Recreation Behaviors Among Snowmobilers: The Role Of Organizational Membership, Liam Carlson Harry Mr.

Graduate Student Theses, Dissertations, & Professional Papers

This study explores the relationship between conflict and recreation behaviors among snowmobilers at western Montana snowmobile access sites (WMSAS) and investigates whether organizational membership influences the types of conflict experienced and attitudes towards appropriate recreation behaviors. Data were collected through an intercept survey, and responses from 250 snowmobilers were analyzed. Descriptive statistics and chi-square tests were used to examine the research questions.

The findings suggest that snowmobilers at WMSAS experienced minimal conflict, with interpersonal conflict related to "hearing others" being the most observed. However, this conflict was not necessarily perceived as a problem by the majority of respondents. Snowmobilers demonstrated …

Climatological, Hydrological, And Economic Analysis Of Agriculture In Montana And The Western U.S.A., Zachary H. Lauffenburger

Graduate Student Theses, Dissertations, & Professional Papers

Many studies have addressed the impact of climate on agriculture; however, fewer studies addressed how farmers adapt to climate change, to what extent implementation of adaptation strategies mitigates economic losses or alters the hydrologic system. Analyses of how historical climate affected not only farmer decision making, but also the economic and hydrological consequences of farmers’ adaptations to climate variations, and projections of the spatiotemporal climatic regimes at finer regional scales are critical for aiding in actionable climate change adaptations. This dissertation helps fill knowledge gaps on the impacts of climate change in rural regions of the agricultural western U.S.A. and …

Fundamental Investigation On Anion Binding Employing The Hydrogen Bond Enhanced Halogen Bond, Jiyu Sun

Graduate Student Theses, Dissertations, & Professional Papers

Noncovalent interactions play a critical role in chemistry and biochemistry. Understanding how to modulate closely situated noncovalent interactions is of utmost importance in the design of functional materials, supramolecular assemblies, pharmaceuticals, and catalysts. Over the past two decades, there has been a significant surge in research and applications on halogen bonds, driven by their exceptional properties such as high directionality and unique tunability when compared to hydrogen bonds. Taking inspiration from nature and other synthetic anion-binding receptors that effectively employ multiple noncovalent interactions in a concerted manner, we have developed an innovative preorganization strategy termed the "Hydrogen Bond Enhanced Halogen …

Impacts Of Climate And Wildfire On Western Larch Regeneration, Spencer T. Vieira

Graduate Student Theses, Dissertations, & Professional Papers

Fire plays a critical role in forests of the western United States (US), but as wildfire and climate deviate from historical patterns, increasing fire activity may significantly alter forest ecosystems. To understand the impacts of changing climate and wildfire activity on conifer forests, we studied the impact of wildfire and annual post-fire climate on western larch (Larix occidentalis) regeneration. We destructively sampled 1651 seedlings from 57 sites within 32 fires that burned at moderate or high severity from 2000-2015 in the northwestern US. Using dendrochronological methods, we estimated germination years of seedlings to calculate annual recruitment rates. We …

Leveraging Hydrogen Bond Enhanced Halogen Bonding For Higher-Order Anion Helix Formation In Foldamers, Eric Arno John

Graduate Student Theses, Dissertations, & Professional Papers

The ubiquity of folding in biopolymers to induce critical functions like information storage, signal transduction, catalysis, and selective binding has inspired chemists to create synthetic analogs called “foldamers” as materials which emulate and complement the remarkable complexity observed in nature. The ingenuity of chemists has yielded unique methodologies to induce secondary structure (folding) for diverse applications in materials science, medicine, and nanotechnology.

Anion foldamers are a specific class of foldamers engineered to recognize and specifically bind anions through noncovalent interactions. Using anions to induce folding has unique challenges. Anions have diverse topologies, pH dependence, and high free energies of solvation …

Evolution And Diversification Of The Novel Chlorophyll D-Based Photosynthetic Apparatus, Nikea Jonelle Ulrich

Graduate Student Theses, Dissertations, & Professional Papers

The origin of novel traits is an important evolutionary process that generates biological diversity. However, we rarely know the underlying mechanisms of diversification following the innovation of a novel trait. Over two billion years ago, the innovation of chlorophyll (Chl) abased photosynthesis by cyanobacteria sparked the oxygenation of Earth, setting the stage for the emergence of multicellular life. Chl a was subsequently acquired by diverse algae and plants, and in the process, these organisms diversified their light-harvesting systems to absorb a range of visible wavelengths (400-700 nm) (1). Due to the ancient origins of Chl a, however, it is difficult …

Reinforcement Learning For Optimal Control In Simulated Greenhouses, Daithi Kahele Leilehua Martin

Graduate Student Theses, Dissertations, & Professional Papers

Demands on agricultural systems will increase as the world population continues to grow. Controlled Environment Agriculture (CEA) is an old idea gaining more recent momentum due to advances in automation, lighting, and climate control. One of the fundamental challenges of CEA is optimal control of the growing environment. We present a method for optimal control in CEA utilizing Deep Reinforcement Learning (DRL). DRL comprises a set of machine learning algorithms that optimize a user-defined reward function. We define this function such that the reward is high when the growing environment is ideal for crop production, and the reward is low …

Predicting Mountain Lion Resource Selection And Abundance In North America, William Connor O'Malley

Graduate Student Theses, Dissertations, & Professional Papers

The relationship between habitat quality and density is well documented in lower trophic levels but to what extent it can be extended to higher trophic levels is unknown. I tested the relationship between habitat quality, home-range size and density using a wide-ranging, well-studied, top carnivore, the mountain lion (Puma concolor). First, I created a second-order resource selection function (RSF) for mountain lions in their current North American range using GPS collar data from 476 individuals in 20 study sites and remotely-sensed landscape data. I used the RSF and home range estimates derived from collared animals to quantify mountain …

“Should Wellbeing Be The Same As Perfection?” A Case Study On Student Wellbeing In Higher Mathematics Education, Marcelo Alonso Almora Rios

Graduate Student Theses, Dissertations, & Professional Papers

Previous research has given the impression that reticent is our hunt for optimal teaching practices, educational goals, and nature of mathematical workings. In this regard, we have (seemingly) ended up with the following inquiries:

• What could the math classroom be for? and
• What has the math classroom been for?

These two questions touch on the scary horns of two other charged philosophical dandruffs. Namely:“What are the aims of teaching mathematics?” and “What should be our objectives in learning it?”

The term ‘positive education’ refers to an educational system engendering both the skills of positive wellbeing and traditional, academic achievement (Seligman …
