How Many Tiny Snails? Circumscription Of Three Species Of Pyrgulopsis (Mollusca: Gastropoda: Hydrobiidae)In Nevada Mountain Springs, Trenton Meadows

Theses and Dissertations

The springsnail genus Pyrgulopsis is one of the most diverse groups of freshwater gastropods in North America (Hershler, 2014), with many species displaying high levels of endemism (Hurt, 2003). This study attempts to circumscribe three putative species of springsnails: Pyrgulopsis serrata, Pyrgulopsis marcida, and a newly identified clade, referred to as Lineage C, from the Ruby Lake National Wildlife Refuge, Nevada, USA and nearby springs. Using an integrative taxonomic approach, we combined morphological, anatomical, and molecular data to examine species boundaries and evolutionary relationships.

Many lines of evidence were considered to determine species boundaries. Phylogenetic analysis of the mitochondrial …

Density Functional Theory And Machine Learning Analysis Of C—C Reductive Coupling From Terminal Cyanido And Cyaphido Complexes, Roberto Magdiel Escobar

Theses and Dissertations

Carbon–carbon (C–C) bond activation has gained increased attention as a direct method for the synthesis of pharmaceuticals and industrial chemistry. Due to the thermodynamic stability and kinetic inaccessibility of the C–C bonds, however, activation of C–C bonds by homogeneous transition-metal catalysts under mild homogeneous conditions is still a challenge. Most of the systems in which the activation occurs either have aromatization or relief of ring strain as the primary driving force. The activation of unstrained C–C bonds of phosphaalkynes does not have this advantage. This study employs Density Functional Theory (DFT) calculations using the Gaussian16 package to elucidate and compare …

Marriage, Courts, And Substantive Equality: A Transformative Interpretation, Kushagr Bakshi

Michigan Law Review

Courts in various jurisdictions have relied on either the right to privacy or the right to equality to offer protections to the LGBTQ+ community. The use of different rights to achieve similar ends may seem like an empty distinction. But the differences in the nature and function of each right evince the differences in the construction of rights across jurisdictions. In the traditional liberal method of conceptualizing rights, privacy is typically a negative right, restricting the state from interfering in intimate relationships between individuals. Courts operating within a transformative framework of rights interpretation, however, rely on the positive right to …

Urban Japanese, Rural American: How Regionality Shaped Nisei Girlhood In Prewar America, Lauren Reiko Yanase

University Honors Theses

This thesis explores Nisei girls' racial and cultural identity formation in the American West before their forced removal to the World War II Japanese American mass incarceration camps. Japanese American history has long been dominated by male narratives, from labor histories of the 1880's first-generation Issei to the American patriotism of the 1930's second-generation Nisei. Japanese American women are generally considered through generational categories, promulgating a linear story of American progress. I argue that regionality is the main factor that shaped Nisei girls' self-identity, employing transcribed interviews with Nisei women born 1924-1929 as primary sources to write narrative histories differentiated …

Cognitive Apprenticeship Strategies For The Media Literacy Classroom, Nate Floyd, Jaclyn Spraetz

Communications in Information Literacy

Inspired by the apprenticeship model of teaching and learning, two instructors report on their efforts to place current events at the center of a semester-long media and information literacy course. They discuss strategies to harness curiosity about contemporary topics (e.g., misinformation, climate change, algorithms, right-to-repair, blockchain, artificial intelligence, etc.), and create engagement-driven course content. The paper provides concrete examples of activities and assignments used to situate learning in real-world contexts and build students' confidence in navigating information independently. This case study offers insights for other educators seeking to apply cognitive apprenticeship principles to media and information literacy instruction.

Centering Relevance In Information Literacy Teaching And Learning, Anne Jumonville Graf

Use Of Electrocardiogram To Evaluate Welfare Of Laying Hens And Chicks During Different Life Stages And Events, Ashley Elizabeth Bigge

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

Three separate studies were conducted to evaluate the welfare of laying hens and chicks during different life stages. The stress responses of mature laying hens in two different scenarios were also investigated. All three studies utilized the electrocardiogram (ECG) as the chosen tool for data collection. Study 1 examined the startle response, prompted by an acute stressor that created sudden movement and noise, in White and Brown Leghorn hens housed in either cages or aviaries. The presence of a chronic stressor, a 23-hour feed failure, was also assessed as a factor. These hens had been surgically implanted with wireless ECG …

Examining The Use Of Problem Transformation Methods In Multi-Target Regression, Bradley Ryan Smith

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

Although the impact of machine learning methods in the educational sciences has been limited, recent opportunities have emerged that can benefit from these flexible methods capable of predicting both linear and non-linear relationships. One emerging area of interest, multi-target regression (MTR), is concerned with the simultaneous prediction of multiple, continuous target variables and is an extension of traditional supervised learning. Problem transformation methods are a subset of MTR methods that seek to exploit the dependencies amongst targets using stacking, chaining, ensembles, or combinations of the three by expanding the Single-Target approach. This is accomplished by using one or more base-learners, …

Examining Factors Of Variance In Energy Metabolism Of Dairy Cattle, Addison Lee Carroll

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

Variation is thought to occur in the use of dietary energy for production in dairy cattle. First, variance can be observed when new methane mitigation strategies are fed resulting in increased H₂ output potentially resulting in downstream effects on estimates heat production via the Brouwer (1965) equation. Therefore, in chapter 3 a review was created to systematically describe the mathematics and theory behind the Brouwer equation, and rederive a heat production equation to integrate H₂ production. Results indicate heat production using the classical Brouwer equation (1965) relative to the rederived equation resulted in an overestimation of heat production …

Mining Work Items To Streamline Software Maintenance Tasks, Salomé Perez-Rosero

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

Software engineering maintenance tasks often require associating code changes into groupings of related units of work to have as much information as possible about the developments toward addressing a specific code task. A comprehensive understanding of how a code task has evolved helps developers make better decisions about changes in the overall codebase, where a commit represents the set of code changes made to the codebase at a specific time. While the concept of work items as logically related code changes has been primarily theoretical, its impact on software maintenance tasks, such as tracing the origins of bugs or fixes …

Code Blue: How Police And Health Care Providers Disrupt Healing For Violently Injured Black Men, Cherrell Green

Kroc IPJ Research and Resources

While Black males are disproportionately impacted by gun homicide, they are also grossly impacted by non-fatal shootings. The impact of gun violence extends far beyond the immediate physical harm inflicted by bullets; this harm can permeate and disrupt personal relationships, create lasting psychological distress, and undermine a sense of safety within communities. However, the needs of injured Black men are often overlooked in public discourse. Despite the prevalence of these traumatic experiences in the lives of low-income Black men, their response to trauma is often treated as pathology, with fewer resources devoted to addressing the adverse consequences associated with these …

Development Of A Multidimensional Index Of Fall Risk For Older Adults: The Cache County Study, Alexandra G. Hammond

All Graduate Theses and Dissertations, Fall 2023 to Present

One out of four adults over the age of 65 are estimated to fall each year in the U.S. alone, with that number expected to rise to 52 million falls per year by the year 2030. Improving accuracy for identification of older adults at a higher risk of falling is increasingly important and may be integral in informing the distribution of limited resources and assist in preventing falls in older adults. This project examined the relationship between previously identified risk factors and fall risk to create multidimensional fall risk indexes for older adults, specific for each sex.

Mathematical And Statistical Methods To Harness Limited Data In Models For Ecological Space Use Under Global Change, Sarah C. Bogen

All Graduate Theses and Dissertations, Fall 2023 to Present

The dynamics of how plants and animals use space in their habitats has important implications for the fields of ecology and conservation. However, understanding and responding to these spatial and temporal dynamics is often limited by data availability, financial resources and biases. As average global temperatures increase, suitable habitats shift poleward and require local populations to move with suitable habitat, adapt to the changing environment, or risk extinction. Capacity to persist without movement may be estimated by considering changes to a combination of habitat characteristics. Capacity to track suitable habitat may be modeled through synthesizing information on species demographic mechanisms …
