Reclaiming Myth: Feminist Reinterpretations And The Creation Of A More Inclusive Narrative, Isabella Iurillo Jan 2025

Reclaiming Myth: Feminist Reinterpretations And The Creation Of A More Inclusive Narrative, Isabella Iurillo

All Student Theses and Dissertations

This thesis examines the role of mythological reinterpretation and its expansion of the literary canon to inclusively reflect human experiences. According to scholars of myth such as Kalloli, Tyagi, and Armstrong, myths are meant to reflect enduring human experiences, making them relatable classics even after thousands of years. However, as the majority of mythological women are largely silenced, misrepresented, or villainized in ancient myth, this reflection is both incomplete and distorted. This thesis examines three contemporary feminist reinterpretations-- Stone Blind by Natalie Haynes, Silence of the Girls by Pat Barker, and Circe by Madeline Miller—each of which gives a voice …

Comparing The Development And Viability Of Horseshoe Crab Eggs Laid In Beach And Salt Marsh Habitats, Daniel A. Sasson, Christopher C. Chabot, Jo-Marie Kasinak, Jennifer Mattei Ph.D., Elizabeth U. Scott, Fletcher K. Hall, Michael R. Kendrick

Biology Faculty Publications

The horseshoe crab, Limulus polyphemus, has recently been found to spawn regularly in salt marshes, despite the long-held assumption that salt marsh sediments are not conducive for embryonic development. Here, we tested the prediction that eggs laid in the salt marsh would develop more slowly and be less viable than eggs laid on beaches. We flagged the nests of spawning horseshoe crabs in the marshes and beaches of three states—South Carolina, Connecticut, and New Hampshire—and then excavated those nests one or three weeks later. We staged the excavated embryos to compare developmental progress between marshes and beaches. We found …


Attention's Loop: A Sculptor's Reverie On The Coexistence Of Substance And Spirit, Elizabeth King, Katherine Wetzel Jan 2025

Attention's Loop: A Sculptor's Reverie On The Coexistence Of Substance And Spirit, Elizabeth King, Katherine Wetzel

Attention's Loop

This is a book about attention and memory. I am a sculptor, so it is also a book about size, dirt, artifice, work, and eye. The text is a set of stories and interruptions that pile up to make a play of overlapping loops. My organizing principle is the image of the round-trip, so one may open the book and step into it at any point. Most of Katherine Wetzel’s photographs are of a single sculpture. It is a self-portrait, a particular kind of round-trip, and it is small: one-half life-size. Called Pupil, it is jointed and movable, and …


A Civil Rights Defense Of Gentrification, Carol Brown Jan 2025

A Civil Rights Defense Of Gentrification, Carol Brown

Law Faculty Publications

Scholars across disciplines such as sociology, economics, and urban planning are writing about gentrification. The literature and beliefs surrounding gentrification are very diverse, but what often connects the various views is a negative perception that gentrification always disadvantages and displaces low-income minority residents, physically or culturally. But the connotations of race and class associated with gentrification in the minds of many do not align with the empirical research and scholarly findings. Thus far in law, there is no thick legal account of gentrification and its legal or policy implications. Much of the legal writing is predicated upon an inaccurate conception …


Living The Good Life In The Anthropocene, Danielle Stokes Jan 2025

Living The Good Life In The Anthropocene, Danielle Stokes

Law Faculty Publications

The Stockholm Resilience Centre has concluded that the number of “planetary boundaries” we are crossing has increased from three in 2009, when the Centre’s researchers first introduced the concept, to six in 2023. Crossing these boundaries means humans are changing basic attributes of planetary systems to the point of risking the future of civilization. And the distinction between “safe” and “just” planetary boundaries raises questions regarding how to conceptualize the “good life.” In this latest in a biannual series of essays, members of the Environmental Law Collaborative explore conceptions of the “good” as well as the various elements necessary to …

Contemporary Normative Values For Five Common Static Standing Tasks On Firm And Compliant Floor Surfaces In Children Two To Thirteen Years, Nancy Darr

Funded Scholarship

Background/Objectives: Static upright tasks, including standing unsupported (SU), eyes closed (SEC), feet together (SFT), tandem (TS), and single limb (SLS), are routinely examined in children and are included in many norm-referenced measures. Existing normative values for these standing tasks may not apply to contemporary children and have not been established across wide age ranges. The primary purpose of this study was to investigate developmental trajectories of and relationships between four static standing positions (SPs [SU, SFT, TS, SLS]) in children aged 2 through 13 years who are developing typically. The effects of altered sensory input, including floor surface (firm and …


Repositioning Antimalarial Drugs As Anticancer Agents: Focus On Tafenoquine, Chris Barton Jan 2025

Repositioning Antimalarial Drugs As Anticancer Agents: Focus On Tafenoquine, Chris Barton

Funded Scholarship

Due to the expensive and lengthy process of drug design and approval, drug repurposing (or repositioning) has become another option for identifying preexisting molecules that may be used for alternative purposes. Recently, some antimalarial compounds have been shown to display efficacy against cancer cell proliferation. In this study, we provide evidence to suggest that multiple preexisting antimalarial drugs can reduce the viability of human cancer cells in culture. Furthermore, we provide the first evidence that one antimalarial, Tafenoquine (LD50 = 9.6 μM in HCT116 cells), is capable of decreasing viability with an efficacy comparable to Etoposide (LD50 = 15.2 μM …


Pedagogical Idealism, Race, And The Specter Of Africa In Josefina Aldecoa’S Historia De Una Maestra And Donato Ndongo’S Las Tinieblas De Tu Memoria Negra, Parker Lawson Jan 2025

Pedagogical Idealism, Race, And The Specter Of Africa In Josefina Aldecoa’S Historia De Una Maestra And Donato Ndongo’S Las Tinieblas De Tu Memoria Negra, Parker Lawson

Funded Scholarship

This article examines two contemporary Spanish novels, Josefina Aldecoa’s Historia de una maestra (1990) and Donato Ndongo’s Las tinieblas de tu memoria negra (1987), to assess the status of pedagogical idealism and experimentation with particular attention to Equatorial Guinea. Where previous scholarly attention to Aldecoa’s novel focuses on the protagonist’s credentials as a progressive pedagogue, this article draws attention to Gabriela’s etapa guineana to argue that the text cripples under the weight of postcolonial analysis as regards race, religion, class, and language. Drawing the novel into comparison with Ndongo’s text, the article argues that Spanish colonial pedagogy flattened, or sought …


Spectral Divergence Prioritizes Key Classes, Genes, And Pathways Shared Between Substance Use Disorders And Cardiovascular Disease, Everest Castaneda, Elissa Chesler, Erich J. Baker Jan 2025

Spectral Divergence Prioritizes Key Classes, Genes, And Pathways Shared Between Substance Use Disorders And Cardiovascular Disease, Everest Castaneda, Elissa Chesler, Erich J. Baker

Funded Scholarship

Substance use disorders (SUDs) are heterogeneous diseases with 

overlapping biological mechanisms and often present with co-occurring disease, 

such as cardiovascular disease (CVD). Gene networks associated with SUDs 

also implicate additional biological pathways and may be used to stratify 

disease subtypes. Node and edge arrangements within gene networks impact 

comparisons between classes of disease, and connectivity metrics, such as 

those focused on degrees, betweenness, and centrality, do not yield sufficient 

discernment of disease network classification. Comparatively, the graph 

spectrum’s use of comprehensive information facilitates hypothesis testing 

and inter-disease clustering by using a larger range of graph characteristics. 

By adding a connectivity-based …

A total of 14 healthy participants [7 male, 7 female; age: 23.46 ± 3.31 years; height: 173.85 ± 8.46 cm; mass: 82.19 ± 11.41 kg; shoe size (men’s): 9.03 ± 2.71 s] were …


Group And State-Specific Estimation In Animal Movement Models Using A Bayesian Approach, Anita Bhandari Sharma Jan 2025

Group And State-Specific Estimation In Animal Movement Models Using A Bayesian Approach, Anita Bhandari Sharma

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This research study investigates statistical approaches for modeling the movement patterns of white-tailed deer in Louisiana using GPS tracking data. We start by classifying the latent behavioral states using a hidden Markov model (HMM) and then integrate those inferred states into a state-dependent step selection framework to evaluate the land cover preferences. Standard HMMs, however, assume the same movement patterns for all animals, overlooking the differences due to characteristics such as sex, age, breeding season, etc.

To address this limitation, we extend the modeling framework to incorporate the group-level structure defined by similar characteristics or conditions to assess whether such …

Biological Sciences Faculty Publications

Heterotrophic feeding on plankton and particulate organic matter (POM) by tropical Scleractinian corals is known to aid in the resistance and recovery from thermally induced bleaching. However, the relative importance of heterotrophy in promoting bleaching resistance and recovery is likely to vary based on ecological context and the severity of heat stress. In 2019, the Pacific Island of Mo'orea experienced mass coral mortality during a widespread marine heatwave. Many Acropora hyacinthus colonies on the shallow reef slope (5 m) were resistant to bleaching, while colonies on the deeper fore reef (14 m) often bleached and subsequently recovered, despite similar thermal …
