More Than Stories: Indigenous Environmental Reciprocity In The Poetry Of Kathy Jetñil-Kijiner, Rebecca Purse
More Than Stories: Indigenous Environmental Reciprocity In The Poetry Of Kathy Jetñil-Kijiner, Rebecca Purse
Theses and Dissertations
This thesis brings to the forefront the traditional stories Marshallese poet, performer, and climate change activist Kathy Jetñil-Kijiner shares in her published poetry. Indigenous studies scholars agree that Indigenous stories have power--power to change, power to inform, and power to heal. The traditional stories in Jetñil-Kijiner's poetry reveal the power of the environment and the potential relationships that can exist between humans and natural beings. While these traditional stories work to disrupt the narrative that Indigenous perspectives, knowledges, and cultures are somehow inferior to their colonial neighbors', they also assert the need for a return to environmental reciprocit--or the establishment …
Exposure To Nature: An Underutilized Component Of Student Mental Health, Jeremy S. Bekker
Exposure To Nature: An Underutilized Component Of Student Mental Health, Jeremy S. Bekker
Intuition: The BYU Undergraduate Journal of Psychology
Nature-exposure interventions on university campuses may serve as an effective addition to overburdened counseling and student support centers. Nature-exposure interventions can work as a preventative health measure on campuses, which can be used adjacently with existing health resources. This paper outlines the potential benefits of nature exposure for students’ physical health, mental well-being, and academic success. Previous research has demonstrated that nature exposure may help reduce cognitive load, decrease negative psychological symptoms, increase psychological coping ability, and lead to better physical health. Many campuses already contain green spaces, defined as any part of an environment that is predominately made of …

Experiential Education In The Writing Classroom: Developing Habits For Citizenship, Anika Shumway
Experiential Education In The Writing Classroom: Developing Habits For Citizenship, Anika Shumway
Theses and Dissertations
As political polarity and social divisiveness increase in the United States, more organizations and scholars are calling on institutions of higher education to rise to the occasion and incorporate into their objectives the development of competent citizenship (The National Task Force). Writing classrooms are particularly suited to these kinds of objectives as writing already proposes relationships between rhetor and audience that have ethical dimensions and require mutual honesty, accountability, and respect (Duffy, "The Good Writer"). Additionally, the Framework for Success, a document that has become central to shaping the goals of writing classrooms, articulates habits of mind, like openness and …

Make Yourselves Gods: Mormons And The Unfinished Business Of American Secularism, Michael Hubbard Mackay
Make Yourselves Gods: Mormons And The Unfinished Business Of American Secularism, Michael Hubbard Mackay
BYU Studies
Borrowing its title from Joseph Smith’s far-reaching Nauvoo theology, Make Yourselves Gods is somehow even more provocative than its title. The average Latter-day Saint reader will chafe under its vocabulary, struggle through its detailed contributions to the study of secularism, and be at odds with its use of queer critique. Furthermore, to the average reader’s disdain, this book will be chewed and discussed for a generation to come. It is not likely to be forgotten.
Global Heat Uptake By Inland Waters, Inne Vanderkelen
Global Heat Uptake By Inland Waters, Inne Vanderkelen
International Congress on Environmental Modelling and Software
Heat uptake is a key variable for understanding Earth system response to greenhouse gas forcing. Recent assessments highlighted that most of the excess energy is stored in the oceans, whereas the land, atmosphere and ice melt take up smaller amounts. However, despite the importance of this heat budget, heat uptake by inland waters has so far not been quantified. Here we use a unique combination of global-scale lake models, global hydrological models and Earth system models from the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP) to, for the first time, quantify global heat uptake by lakes, reservoirs and rivers over the …
Integrated Workflow For Use Of Unmanned Aerial Vehicles In Monitoring Water Resources, Mary Kay Camarillo
Integrated Workflow For Use Of Unmanned Aerial Vehicles In Monitoring Water Resources, Mary Kay Camarillo
International Congress on Environmental Modelling and Software
Unmanned aerial vehicles (UAVs) offer possibilities to enhance monitoring of river basins, wetlands, and other important water bodies. Opportunities to use UAVs in environmental studies include periodic and autonomous flights to detect and provide warnings of algal blooms, access to areas that are difficult to explore, and more rich data sets of water coverage, vegetation, and other features. In order to benefit from UAV technology, appropriate flight planning, data collection, and post-flight data processing strategies must be developed. In this study, we present recommendations for integrating UAVs into the study of water bodies. We first provide an overview of the …
Using Dynamic Risk Profiles To Create Adaptation Pathways For Flood Risk Management, Hedwig Van Delden
Using Dynamic Risk Profiles To Create Adaptation Pathways For Flood Risk Management, Hedwig Van Delden
International Congress on Environmental Modelling and Software
Floods pose a risk to societies all over the world. This risk is likely to increase due to a combination of drivers, including climate change, urbanization and changing demographics. Understanding how the future may unfold and what the key uncertainties are is critical in designing disaster risk management strategies, as we will only be able to reduce flood risk into the future if we account for these drivers. Accepting that we need to embrace uncertainty also means that we can no longer develop a single plan of risk reduction options that is effective for the coming decades and acceptable to …
Local Biogeophysical Effects Of Deforestation, Steven De Hertog
Local Biogeophysical Effects Of Deforestation, Steven De Hertog
International Congress on Environmental Modelling and Software
The impact of deforestation on climate is mostly pronounced through net carbon emissions (biogeochemical effects), leading to a global warming. However, deforestation also alters the water and energy cycles (biogeophysical effects), which can cause a local warming or cooling depending on the region. This additional warming can potentially offset or even exacerbate the initial global warming signal caused by the biogeochemical effect. The results of earth system models show a large spread on the magnitude of biogeophysical effects and can even vary on the sign of these impacts for some regions. Thus, uncovering the uncertainty related to the biogeophysical effect …
Towards A Multi-Criteria Approach To Validate Agent-Based Model For Socio-Ecological Systems Transitions, Quang Bao Le
Towards A Multi-Criteria Approach To Validate Agent-Based Model For Socio-Ecological Systems Transitions, Quang Bao Le
International Congress on Environmental Modelling and Software
Due to inherent complexity, path-dependency, deep uncertainty of socio-ecological systems (SES) in transition that agent-based models (ABM) are often meant to simulate, validation of ABM for SES is expanded beyond the straightforward evaluation of numerical fits between simulated and observed patterns in time and space. With a metaphorical thought about meaningful uses of the complex system models, the validity of this model type lies within the continuous review/evaluation with multiple criteria to inform users about the model’s usefulness, its limitations and development needs. From literature of model validation, we outline multiple criteria that should be considered in ABM evaluation: (1) …
Variable Uptake Of Selenium: Exposing Bryophytes In-Situ To A Se-Gradient Watershed, Del Wayne R. Nimmo, Scott J. Herrmann, James S. Carsella, Igor V. Melnykov
Variable Uptake Of Selenium: Exposing Bryophytes In-Situ To A Se-Gradient Watershed, Del Wayne R. Nimmo, Scott J. Herrmann, James S. Carsella, Igor V. Melnykov
Western North American Naturalist
We investigated the uptake of selenium (Se) at 14 sites in a Se-rich watershed, using an aquatic bryophyte (Hygrohypnum ochraceum). We expressed uptake using the symbol Kd to underscore the relationships between Se in water and Se in plants as “partitioning coefficients” related to the bases of aquatic food chains. A 2-way analysis of variance (ANOVA) was performed with Kd as the dependent variable and season and stream segment (location) as main effects. Selenium concentrations, measured as dissolved Se, total Se, and pore water Se, were also examined. There were significant differences in Kd values …
Analyzing The Effect Of Cmip5 Climate Projections On Streamflow Within The Pajaro River Basin, Ranjit Bhandari, Ajay Kalra, Sanjiv Kumar
Analyzing The Effect Of Cmip5 Climate Projections On Streamflow Within The Pajaro River Basin, Ranjit Bhandari, Ajay Kalra, Sanjiv Kumar
Open Water Journal
The current study evaluated the effect of climate change on regional streamflow using General Circulation Models (GCMs) from the Coupled Model Intercomparison Project (CMIP5) for the Pajaro River Watershed (PRW) in central California. The 1/8° latitude-longitude resolution bias-corrected and downscaled CMIP5 projections were utilized under four Representative Concentration Pathways (RCP2.6, RCP4.5, RCP6.0 and RCP8.5). Csiro-mk3-6 and canesm2 models projected an increase of 3.1°C in annual average daily maximum temperature and 3.4°C in annual average daily minimum temperature respectively in 2070-2099 period under RCP8.5 scenarios. The dry months would continue to receive diminished precipitation throughout the century. The streamflow was increasing …

Trajectory Optimization And Design For A Large Number Of Unmanned Aerial Vehicles, Jenna Elisabeth Newcomb
Trajectory Optimization And Design For A Large Number Of Unmanned Aerial Vehicles, Jenna Elisabeth Newcomb
Theses and Dissertations
An unmanned aerial vehicle (UAV) swarm allows for a more time-efficient method of searching a specified area than a single UAV or piloted plane. There are a variety of factors that affect how well an area is surveyed. We specifically analyzed the effect both vehicle properties and communication had on the swarm search performance. We used non-dimensionalization so the results can be applied to any domain size with any type of vehicle. We found that endurance was the most important factor. Vehicles with good endurance sensed approximately 90% to 100% of the grid, even when other properties were lacking. If …
Spatial Distribution Of Roots Across Three Dryland Ecosystems And Plant Functional Types, Jessica G. Swindon, William K. Lauenroth, Daniel R. Schlaepfer, Ingrid C. Burke
Spatial Distribution Of Roots Across Three Dryland Ecosystems And Plant Functional Types, Jessica G. Swindon, William K. Lauenroth, Daniel R. Schlaepfer, Ingrid C. Burke
Western North American Naturalist
Roots play a critical role in carbon storage, carbon cycling, and resource acquisition in dryland ecosystems, yet their distribution and production patterns are poorly understood. We aimed to compare the vertical and horizontal distribution of roots of the dominant plant functional types across 3 dryland ecosystems in the western Great Plains of the United States. We collected consecutive soil cores from directly under plants to 29 cm away from the center of plant individuals (horizontal plane), to a 20-cm depth (vertical plane). Across the 3 ecosystem types, grass root biomass decreased with depth and, for the sagebrush steppe, at a …

Impacts Of Climate Change On Groundwater Recharge In Wyoming Big Sagebrush Ecosystems Are Contingent On Elevation, Lukas W. Lindquist, Kyle A. Palmquist, Samuel E. Jordan, William K. Lauenroth
Western North American Naturalist
Water is the most limiting and important natural resource in drylands, where low precipitation, high evaporative demand, and drought events are common. Groundwater is the critical resource for human livelihoods to persist through the intra-annual dry periods in dryland ecosystems. Overexploitation of groundwater resources and the externalities associated with depleted aquifers make understanding the ecohydrology of drylands an essential issue. We focus on the water balance and climatic drivers of big sagebrush ecosystems, an important dryland ecosystem type in Wyoming that covers a large spatial extent. The goal of this project was to understand how groundwater recharge (GWR) may change …
