Textual Sediments: Genre And The Planetary Novel, William Bowden

Open Access Dissertations

This dissertation investigates how twenty-first-century prose fiction navigates the ecological and temporal dimensions of planetary crisis. In response to accelerating pressures - climate change, ecological collapse, and the intensification of capitalist modernity - literary studies has turned increasingly to the planetary as a conceptual frame. Yet this shift has often outpaced the development of adequate critical vocabularies and narrative methodologies. By drawing on ecocriticism, narrative theory, phenomenology, and related fields, Textual Sediments proposes a new framework for reading what it terms the planetary novel: a sedimentary genre characterized by temporal layering, formal hybridity, and a recursive engagement with scale. Through …

Reverse Geometric Dispersion In The Beaufort Sea: Dissecting Sound Propagation At Long Ranges In Ducted Profiles, Jessica Desrochers

Open Access Dissertations

Acoustic propagation in the Arctic is evolving as surface temperatures increase and ice melts, resulting in a changing sound propagation environment. This study investigates the acoustic arrival structure in the Canada Basin and its connection to the underlying sound speed profiles. Two Seagliders were deployed in the summer of 2016 and 2017, diving in a sawtooth pattern collecting conductivity, temperature, and depth (CTD) data as part of the Canada Basin Acoustic Glider Experiment (CABAGE). These data are used to calculate sound speed profiles used to predict and understand acoustic arrival structures.

Per- And Polyfluoroalkyl Substances (Pfas) Effects On Tissue Disposition, Proteome, And Health Effects, Juliana Agudelo Areiza

Open Access Dissertations

Per- and polyfluoroalkyl substances are a class of nonbiodegradable synthetic aliphatic environmental toxicants that are ubiquitous in the environment. A small subset, specifically perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA), have been designated as highly hazardous to human health by the Environmental Protection Agency (EPA) under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). PFOA and PFOS-associated adverse health effects include, but are not limited to, immune suppression, thyroid dysfunction, increased serum cholesterol, liver damage (i.e., alanine aminotransferase (ALT)), and developmental toxicity (i.e., low fetal birth weight and neurotoxicity). In this doctoral dissertation, it was hypothesized that environmental PFAS …

Essays On Human Decisions Related To Water Quality Problems In The United States, Sonia M. Refulio Coronado

Open Access Dissertations

Water pollution remains a pervasive and inequitable environmental threat in the United States, with mounting evidence that its burdens - whether in recreational or drinking water contexts - are unevenly distributed across communities. Urbanization, aging infrastructure, and industrial contamination have degraded both coastal waters and drinking water systems, posing serious public health and welfare concerns. At the same time, the extent to which water quality influences behavioral decisions, such as beach recreation or household adoption of water filters, remains poorly understood. Although drinking water pollution is widely ranked as a top environmental concern in national surveys, public knowledge of specific …

Stability And Global Dynamics Of Autonomous And Nonautonomous Discrete Population Models With Stocking, Harvesting, And Cooperation, Sam Habach

Open Access Dissertations

This dissertation investigates the local and global behavior of several classes of discrete population models involving stocking, harvesting, and cooperation. The study is divided into three major manuscripts, each offering new theoretical in sights, bifurcation results, and applications to real-world data.

In Manuscript 1, we study the Beverton-Holt population models with constant and proportional stocking and harvesting, as well as sigmoid Beverton-Holt models under constant stocking and harvesting, both in autonomous and non-autonomous settings. We analyze stability and explore global dynamics using established local and global dynamics theorems, bifurcation theory, and explicit solutions when available. Special attention is given to …

Incorporating Time-Varying Parameters And Climate Drivers Into Fisheries Models, Rachel Catherine Marshall

Open Access Dissertations

Commercial fishing is a highly valuable industry in the United States and globally, and as such, managing based on the best available science is necessary to maintain important fish stocks. Some parameters in stock assessment models that are assumed to be constant over age and time may actually vary to an extent that stock assessment modeling results could be improved by allowing the parameters to vary in the models. In the present dissertation, two stock assessment parameters that are typically held constant are explored for potential time or age variance. Potential environmental drivers of nonstationary parameters are also explored. Productivity, …

A Multispectral Analysis Of High Redshift Quasars And Their Energy Production Mechanisms, Erik Carlson

Open Access Dissertations

We present a complete sample of radio-loud (P_3.0 GHz = 10^27.26 W/Hz) high-redshift (z ≥ 2.5) quasars in the Northern Hemisphere (δ ≥ 0). Each source was imaged with a user-defined imaging protocol developed for the Very Large Array Sky Survey. Higher-resolution images were generated from archival observations and new Enhanced Very Large Array observations (Project Code: 24B-010).  We produced 407 images of galaxies, where we are likely the first humans to see them. Twenty of these sources were high-redshift jets which increased the number of known high-redshift jets by 69%. This sample represents one of the largest …

Millennial Pulses Of African Dust And Itcz Shifts In The Eastern Equatorial Pacific, Danielle E. Schimmenti, Franco Marcantonio, M. Roxana Sierra Hernández, Matthew W. Schmidt

OES Faculty Publications

We present high-resolution records of detrital Pb and Nd isotopes from marine core site MV1014-02-17JC (00° 10.8297’S, 85° 52.0042’W) in the Eastern Equatorial Pacific (EEP) and use a Bayesian isotope mixing model, MixSIAR, to quantify global dust source contributions since the onset of the last glaciation 30,000 yr ago. We find that in addition to South American dust from the Andean margin, North African dust from the Saharan desert makes up significant proportions of the EEP dust delivered to the site of study. The proportion of North African dust was significantly enhanced during the cold Northern Hemisphere stadials, Heinrich Stadial …

Multi-Centennial Spatial Coherency Among Atlantic Tropical Cyclones From Simulated And Reconstructed Storm Records, Richard M. Sullivan, Elizabeth Wallace, Sylvia Dee, Gabiel A. Vecchi, Wenchang Yang, Kerry Emanuel

OES Faculty Publications

Proxy-based reconstructions of long-term Atlantic tropical cyclone (TC) variability reveal low-frequency oscillations in regional TC landfalls over the Common Era. However, the limited spatial coverage and increased uncertainty of the proxy records complicates assessments of this feature. Here we present a new multi-ensemble set of synthetic TCs downscaled from the Last Millennium Reanalysis project, which is based on sea surface temperatures that more accurately reflect past conditions. Throughout ensemble members, there are coherent multi-centennial shifts in landfalls with persistent intervals of increased (decreased) occurrence along the eastern US concurrent with inverse activity in the southwest Caribbean and Gulf of Mexico, …

Optimizing An Image Analysis Protocol For Ocean Particles In Focused Shadowgraph Imaging Systems, Huanqing Huang, Alexander B. Bochdansky

OES Faculty Publications

A variety of imaging systems are in use in oceanographic surveys, and the opto-mechanical configurations have become highly sophisticated. However, much less consideration has been given to the accurate reconstruction of imaging data. To improve reconstruction of particles captured by Focused Shadowgraph Imaging (FoSI)—a system that excels at visualizing low-optical-density objects, we developed a novel object detection algorithm to process images with a resolution of ~ 12 μm per pixel. Suggested improvements to conventional edge-detection methods are relatively simple and time-efficient, and more accurately render the sizes and shapes of small particles ranging from 24 to 500 μm. In addition, …

Diving Into Watershed Science And Education: Blending Science, Storytelling, And Professional Practice In Northern Michigan, Mara Clare Pellerito

Graduate Student Portfolios, Professional Papers, and Capstone Projects

This portfolio expands understanding of the relationship between watershed education and science through storytelling, lived experiences, and research. In northern Michigan, the invasive Myriophyllum spicatum threatens watershed health by forming dense patches that block sunlight, exclude native plants and wildlife, and retain harmful nutrients later released by herbicide treatment. The Lake Leelanau Lake Association has managed this species with preventative and restorative practices since 2020, and this portfolio examines their results through scientific study and practical experience from the summers of 2024 and 25. It also explores how education serves as a stepping stone from childhood curiosity to a lifetime …

Exploring Pre-Kindergarten Teachers' Experiences With Engaging Black Boys In Literacy Instruction, Airreia Faith Pierce

Walden Dissertations and Doctoral Studies

Recent studies convey the critical need for teachers to use culturally relevant pedagogy (CRP) to engage Black boys in literacy instruction. The problem was that in the Sunshine School District (SSD: a pseudonym), pre-kindergarten (pre-K) teachers found it challenging to engage Black boys in literacy instruction. Framed by Ladson-Billings’s CRP, the purpose of this basic qualitative study was to explore how pre-K teachers engaged Black boys in literacy instruction and how teachers’ instructional practices aligned with CRP. To collect data, a purposeful sample of 11 pre-K teachers from SSD participated in semistructured interviews. Thematic analysis, using open coding, was applied …
