Impacts Of Artificial Habitat Structures On Overwinter Fish Survival And Fish Presence In South-Central Nebraska, Logan Dietrich

Biology Theses, Dissertations, and Student Creative Activity

Artificial lentic systems, such as borrow pits, often lack structural complexity due to construction practices and steep bathymetry, limiting features like vegetation and woody debris essential for fish communities. To address this, artificial structures made of materials such as polyvinyl chloride are increasingly used by state and federal agencies to supplement habitat. However, little information is known about the impact these structures have on fish communities. Thus, the objectives of this study were to examine the influence of Georgia cubes in borrow pit impoundments on overwinter survival of sub-stock and ≥ stock Bluegill (Lepomis macrochirus) and Largemouth Bass …

Wither, Religious Liberty, Amanda Harmon Cooley

BYU Law Review

During the oft-deemed Constitutional Revolution of 1937, the U.S. Supreme Court effected a significant sea-change in its substantive due process liberty analysis. In West Coast Hotel v. Parrish, the Court held that the Due Process Clause’s liberty provision does not protect absolute freedom of contract, signaling the demise of the Lochner era. Almost a century later, the current Supreme Court’s supermajority bloc is now infamous for its own seismic shift in liberty analysis. This Court’s incontrovertible Constitutional Revolution of 2022 was not limited to only substantive due process, which the Court shifted with its decision in Dobbs v. Jackson Women’s …

Hyperspectral Band Selection Via Heterogeneous Graph Convolutional Self-Representation Network, Junde Chen, Wenzhao Li, Surendra Maharjan, Hesham El-Askary

Mathematics, Physics, and Computer Science Faculty Articles and Research

Hyperspectral image (HSI) band selection (BS) plays a crucial role in HSI dimensionality reduction, aiming to identify a representative subset of bands with minimal redundancy. However, conventional BS approaches primarily operate in the Euclidean domain, often overlooking the structural characteristics of pixels and spectral bands, such as spatial continuity and spectral dependencies. In addition, they handle each HSI as an integrated unit to harness implicit spatial information, disregarding spatial distribution variations across different homogeneous regions. To fully leverage structural information, this study introduces a novel BS method, termed the dual heterogeneous graph convolutional network with enhanced self-representation (ESR-HGCN), for HSI …

Broken Rituals: Contending Gods And Sacred Cows In Religious Racial Reconciliation And Race Relations, Ewart E. Forde

LSU Doctoral Dissertations

Race remains one of the most important determinants of a host of sociological outcomes despite claims that social characteristics such as class matter more. For example, racial inequalities are apparent in educational outcomes and regarding to asset-ownership. Perhaps the most troubling evidence of persistent racial inequities is the killing of Black people by law enforcement officials or civilians while they are engaged in such mundane activities, such as jogging in a neighborhood or selling compact discs (CDs). In the aftermath of these unnatural killings, there are often calls for racial reconciliation, faith based racial reconciliation. In times where it appears …

This is the first report of S. granti in US waters of the Gulf of Mexico; previous eBird reports indicate occasional presence in Caribbean waters off Costa Rica (2018) and Colombia (2020). As many as 20% of all marine and waterbird species occurring in the Gulf of Mexico have core ranges in the Pacific Ocean or its continental margins. Dispersal by Pacific birds …

Nape Coloration Varies With Sex, Not Age, Among Great Shearwaters Ardenna Gravis, Ewan D. Wakefield, Anna R. Robuck, Kevin D. Powers, Robert A. Ronconi, Peter G. Ryan, David N. Wiley

Marine Ornithology

Most petrels (family Procellariidae) exhibit little or no obvious variation in plumage with age or sex, either because plumage performs no sexual function or does so in a way poorly perceptible to humans. This limits the inferences that can be made from visual observations of petrels at sea. However, it has been suggested that nape coloration of Great Shearwaters Ardenna gravis whitens with age. Here we test this supposition using observations of known-age-class individuals. We necropsied birds bycaught around Gough Island, a major breeding colony in the South Atlantic Ocean, and in Massachusetts Bay, a wintering area off the northeastern …

Modeling Breeding Habitat Preferences Of Tahiti Petrel Pseudobulweria Rostrata On Ta‘Ū, American Samoa, A. J. Titmus, C. A. Lepczyk

Marine Ornithology

Understanding the prevalence and use of breeding habitat of seabird species is important for evaluating appropriate conservation and management strategies. Seabirds are one taxonomic group for which we have relatively few species distribution studies, particularly on remote islands. To address this limitation, the goals of this study were to (1) build and use a species distribution model to identify which differences in habitat structure, physical characteristics, and environmental conditions affect Tahiti Petrel Pseudobulweria rostrata nesting presence on the island of Ta‘ū, American Samoa; and (2) evaluate how important nesting habitat characteristics can identify the fine-scale extent and location of suitable …

Black Oystercatcher Haematopus Bachmani Productivity In California And Oregon And The Effects Of Nest Site And Environmental Covariates, Anna Weinstein, Joseph Liebezeit, Daniel Orr, Ryan D. Carle, Timothy D. Meehan

Marine Ornithology

Black Oystercatcher Haematopus bachmani is a species of conservation concern due to its small global population, reliance on somewhat restricted intertidal habitat, and vulnerability to climate change impacts. Concern for this species, along with a lack of demographic information from the southern portion of its range, gave rise to a community science project to monitor pair productivity, nest characteristics, and nest disturbance from 2012 through 2022 across three study regions in Oregon and California. A clear spatial gradient existed in productivity, with relatively low values in the southern region (0.37 fledged young per pair per year, 95% confidence interval [CI] …

Distribution Of Alkylamines In Surface Waters Around The Antarctic Peninsula And Weddell Sea, Arianna Rocchi, Mark F. Fitzsimons, Preston Chebai Akenga, Ana Sotomayor, Elisabet L. Sà, Queralt Güell-Bujons, Magda Vila, Yaiza M. Castillo, Manuel Dall'osto, Dolors Vaqué, Charel Wohl, Rafel Simó, Elisa Berdalet

School of Geography, Earth and Environmental Sciences

Alkylamines, volatile organic nitrogen compounds with low molecular weight, are present in the surface ocean and participate in the marine biogeochemical nitrogen cycle, atmospheric chemistry and cloud formation. Alkylamines have been detected in polar regions, suggesting that these areas constitute emission hotspots of these compounds. However, knowledge of the sea surface distribution patterns and factors modulating alkylamines remain limited due to their high reactivity and low concentrations, which hamper accurate measurements. We investigated the presence and distribution of alkylamines in seawaters around the Antarctic Peninsula and the northern Weddell Sea during the late austral summer and explored their potential links …

Selective Ring-Opening Of Furfuryl Alcohol To 1,5-Pentanediol Over Pt/Aluminosilicates, Lee J. Durndell, Vannia C. Dos Santos-Durndell, Atal Shivhare, James A. Hunns, Karen Wilson, Adam F. Lee

School of Geography, Earth and Environmental Sciences

Biomass-derived diols are key chemical building blocks for the sustainable chemical manufacturing of textiles and plastics, however their synthesis by a selective, scalable process from holocellulose is challenging. Furfuryl alcohol (FALC) is a potential precursor to 1,5-pentanediol (1,5-PeD) through acid-catalysed hydrogenolysis, and hence the impact of oxide support acidity on this reaction over Pt nanoparticles was investigated under batch and continuous flow in toluene. Platinum dispersed over weakly acidic fumed silica and mesoporous SBA-15 supports was almost inactive towards furfuryl alcohol at 150 °C and 10 bar H2 and promoted decarbonylation and hydrodeoxygenation of FALC to furan and methyltetrahydrofuran, respectively. …

A Stakeholder Approach To The Regulation Of On-Premise Signs, Christopher Auffrey, Mathew S. Isaac, Steven W. Kopp, Hannah Marriott, Aparna Sundar, Charles R. Taylor, Franklin Velasco Vizcaino

Marketing Faculty Publications and Presentations

Using stakeholder theory, this article introduces a framework to inform decision making with respect to the regulation of on-premise signs. Because signage resides in a broader, shared environment and its regulation largely takes place at the local level of government, it can be considered unique among most other marketing-related communications. On-premise signs are important to individual businesses and the communities in which they are used, but at the same time, they are “out in the world,” cannot be avoided, and may not be relevant to or welcomed by many consumers who are exposed to them. A transformative consumer research lens …

The Journal of Values-Based Leadership

Laying the foundation for understanding ethical leadership, we begin this paper by identifying a framework for understanding the leader’s roles based upon five dimensions for understanding leadership’s duties and responsibilities. We present a model for ethical decision making that addresses the complex factors of ethical decision-making based upon a virtuous continuum. We then review five levels of leadership identified by Jim Collins (2001) in his research about leaders – identifying the special significance of Level 5 leaders who enabled their companies to evolve from “Good” to “Great.” We describe the characteristics of leaders in each of Collins’ five leadership levels …

The Language Of Film And Television

Communication Research Trends

An increasing number of people receive most of their news, entertainment and even religious inspiration through the visual media of film, television or illustrated magazines. We all "watch" television.James Monaco notes that some cats watch television attentively! But how well do we grasp the specific language of the visual media?

In countries such as the U.S., there is evidence that the post-1950 generation that has grown up with television has a pattern of thinking more attuned to the visual than to print media. Yet, some cross-cultural studies suggest that many American children, for all of the long hours of TV …

The Intersection Between Child Marriage And Climate Change: An Example Of Malawi, Musu Bakoto Sawo

Journal of African Policy Studies

Child marriage affects 39,000 girls daily, totaling 650 million women married before age eighteen globally. While driven by poverty, tradition, and limited education, climate change is emerging as a significant new factor, particularly in developing nations such as Malawi, where 42% of girls marry before age eighteen. An estimated 1.5 million girls in Malawi are at risk due to climate-exacerbated food insecurity and displacement. This paper, using feminist theories of intersectionality, postcolonial feminism, and feminist political ecology, examines the complex link between climate change and child marriage in Malawi. It critiques existing international, regional, and domestic policies, highlighting their inadequacy …

African Feminist Theories And The Gendered Dimensions Of Climate Change In Africa, Manase Kudzai Chiweshe

Journal of African Policy Studies

This paper analyzes how African feminist theories can provide nuanced insights into the gendered dimensions of climate change across the continent. African feminist theories provide essential insights into the everyday lived experiences of women within African spaces, allowing for a contextual analysis of the impacts of climate change. There has also been a growing recognition of the need to identify the gender-differentiated impacts of climate change. The main argument is not only that climate change will be experienced by men and women differently but also that the impacts will hurt women more severely. Yet this theorization must employ theoretical lenses …

District Impact On State-Wide Charter School Policy: Has Normandy Schools Collaborative Punctuated The Equilibrium? Charter School Policy Analysis Of The Missouri Department Of Elementary And Secondary Education, Tracey L. Cannon

Dissertations

Abstract

Punctuated Equilibrium Theory, as applied by Niles Eldredge and Stephen Jay Gould (1941-2002) to the study of species evolution, examined the infrequency of morphological change or stasis discontinuity.1 While groundbreaking in the field of Paleontology and the study of fossil change, the theory has been well-fitting to the decision sciences as introduced by Baumgartner and Jones2, in their 1993 and 2010 publications. Recognizing typical, incremental policy change, its use in this research looks at how stasis, stagnant policy can be punctuated by changes in political or societal views. This study examines the impact of heightened problem discussion for agenda …

A Narrative Study Of How Secondary School Teachers Experience Generative Ai Writing Tools In The English Language Arts Classroom, Nick Brodell

Doctor of Education (EdD)

With the presence of artificial intelligence (AI) programs such as ChatGPT commonplace in secondary English language arts (ELA) classrooms, scholars and practitioners are both curious and skeptical about the technology’s ability to help students improve their ELA skills. Teachers have been using tutoring software and Web 2.0 technologies for decades, yet AI writing tools offer new functionalities. Teachers and administrators have experiences engaging with the benefits and burdens of the technology, and scholars of composition pedagogy, ITS (intelligent tutoring systems), and ML (machine learning) have theories about students using it for skills acquisition and practice. This study collected and analyzed …
