A Snapshot Of Ancient Microbial Life: Microorganisms And Organic Compounds In Primary Fluid Inclusions In Bedded Halite, Neoproterozoic Browne Formation Of Central Australia, Sara I. Schreder-Gomes

Graduate Theses, Dissertations, and Problem Reports (ETD)

Modern shallow brine environments contain an abundance of microorganisms. Microorganisms, mineral crystals, and air bubbles can be trapped with those brines in primary fluid inclusions in bedded halite as it grows in shallow saline surface waters. Primary fluid inclusions and their contents can be preserved, unaltered, for millions of years.

The ~830 million-year-old Browne Formation of central Australia contains intervals of bedded halite with unaltered primary fluid inclusions. Intervals of bedded halite were sampled in the Empress 1A core from ~1480 m – 1520 m depths. Here, I used petrography to describe suspect microorganisms and organic compounds that were trapped …

Factors That Influence Entrepreneurship And Digital Talent In The Rural Heartland: Missouri, Kansas, Oklahoma, And Arkansas, Chett Daniel

Murray State Theses and Dissertations

The current state of many rural communities demands new, more relevant economic development strategies. Traditional models of rural economic development often rely on farming, natural resource extraction, and industrial type jobs that rely on lower cost labor usually focused on manufacturing of product or food. Farm jobs declined decades ago. Offshoring, and more recently automation is rapidly reducing the number of jobs available in rural areas. Jobs and economic vitality are critical to sustaining or growing communities. While traditional methods of industry attraction are still viable strategies to spur economic activity, rural areas must develop concurrent economic strategies driven by …

Hazardous Metal Additives In Plastics And Their Environmental Impacts, Andrew Turner, Montserrat Filella

School of Geography, Earth and Environmental Sciences

Historically, many additives and catalysts used in plastics were based on compounds of toxic metals (and metalloids), like arsenic, cadmium, chromium(VI), and lead. Despite subsequent restrictions, hazardous additives remain in plastics in societal circulation because of the pervasiveness of many products and the more general contamination of recycled goods. However, little is understood about their presence and impacts in the environment, with most studies focusing on the role of plastics in acquiring metals from their surroundings through, for example, adsorption. Accordingly, this paper provides a review of the uses of hazardous, metal-based additives in plastics, the relevant European regulations that …

Can Stable Isotopes From Tree Rings Improve Our Understanding Of Past Variability In The Southern Annular Mode?, Zachary Grzywacz

Graduate Theses, Dissertations, and Problem Reports (ETD)

Few annually dated stable isotope records exist across Oceania. In mid- to high-latitude locations in South America, tree-ring stable isotopes provide information about past climate dynamics such as the Southern Annular Mode (SAM). The SAM drives latitudinal shifts in Southern Hemisphere westerly winds, influencing temperature and moisture delivery across the mid- to high-latitudes, including Tasmania. Combinations of paleoclimate proxies from across the Southern Ocean might provide insight into dynamic processes like the SAM that are difficult to measure with a single proxy. Measuring stable carbon and oxygen isotope ratios from tree rings in Tasmania could provide complementary data to contribute …

Assessing Synthetic Aperture Radar (Sar)-Derived Temporal Patterns And Digital Terrain Data For Palustrine Wetland Mapping, Jaimee L. Pyron

Graduate Theses, Dissertations, and Problem Reports (ETD)

Palustrine wetland systems are important ecosystems and provide numerous ecosystems services to support society. Unfortunately, they remain under constant threat of devastation due to land use practices and global climate change, which underscores the need to identify, map, and monitor these landscape features. This study explores harmonic coefficients and seasonal median values derived from Sentinel-1 synthetic aperture radar (SAR) data, as well as digital elevation model (DEM)-derived terrain variables, to predict palustrine wetland locations in the Vermont counties of Bennington, Chittenden, and Essex. Support vector machine (SVM) and random forest (RF) machine learning models were used with various combinations of …

Francis Poulenc: The Compositional Influences Of Les Six And Sergei Prokofiev On The Poulenc Oboe Sonata (1962), Evan Klein

Graduate Theses, Dissertations, and Problem Reports (ETD)

This research document contextualizes the compositional influences found within Francis Poulenc’s oboe sonata. In his lifetime, Poulenc was an extremely well-connected individual, often dedicating his works to his close friends and patrons. The Sonata for Oboe and Piano, in particular, is one of these compositions dedicated to his friend and famous composer Sergei Prokofiev. Written in 1962 toward the end of Poulenc’s life, he glanced back to the start of the twentieth century for inspiration and source material. The oboe sonata is then a collage of sorts—it takes on the shared contextual principles of Les Six in which he was …

Infusing Literacy Across The Curriculum Through Experience For Low Literacy-Ability Adolescents, Deborah Olive Jack

Walden Dissertations and Doctoral Studies

AbstractAdolescents are not acquiring the necessary literacy skills to engage with complex texts for high school, higher education, and eventual employment. However, it is unclear what strategies teachers use to infuse literacy instruction across the curriculum and how useful training they have received to use these strategies has been. Guided by Dewey’s theory of experience, this basic qualitative study sought to understand the strategies teachers use to infuse literacy through experience, training teachers received, and their views regarding how strategy training can be improved. Participants were 12 purposefully selected teachers from three junior secondary schools in an urban school district …

Theses and Dissertations

The purpose of this dissertation was twofold: to determine how graduates of North Dakota high schools perceived their educational experiences in relation to preparing them for their adult lives, and to determine how curriculum and graduation requirements at the time of this study in North Dakota Century Code (NDCC) 15.1-21, titled “Curriculum and Testing,” fulfilled the purpose of education in North Dakota. This study used a mixed-methods research design and includes a literature review and an online survey of 81 North Dakota high school graduates in the Dickinson area regarding the readiness of students who have graduated from North Dakota …

The Evolution Of An Institution And Student Misconduct Polices: A Study Of Minnesota State University Moorhead (Msum), 1887-2007, Ashley Jo Atteberry

Theses and Dissertations

An institution of higher education holds certain beliefs about the personal growth of students while they are enrolled. The behavior prohibited within the student misconduct policies reflect the norms within the larger society as well as the expectations specific to the learning environment within the institution. Students adhering to the expectations defined in these policies are perceived as embracing these beliefs, which enhances the character and resulting community member the student becomes upon graduation. In an opportunity to understand and resolve the concern of having an overly legalistic published policies for student misconduct, this qualitative study reviewed the content of …

North Dakota's New Frontier: Unmanned Aircraft, Matthew D. Dunlevy

Theses and Dissertations

Unmanned Aircraft, or drones, represent a modern-day frontier, one that is, as yet, neither fully explored nor fully developed. The state of North Dakota has moved into the frontier and is deeply involved in its exploration and development. The state has invested tens of millions of dollars in the Unmanned Aircraft Systems (UAS) industry, an investment that has helped to attract tens of millions of additional dollars from military sources and from private business firms. The University of North Dakota’s John D. Odegard School of Aerospace Sciences, long-recognized as among the leading aviation schools in the nation, is at the …

Elevated Growth And Biomass Along Temperate Forest Edges, Luca L. Morreale, Jonathan R. Thompson, Xiaojing Tang, Andrew Reinmann, Lucy R. Hutyra

Advanced Science Research Center

Fragmentation transforms the environment along forest edges. The prevailing narrative, driven by research in tropical systems, suggests that edge environments increase tree mortality and structural degradation resulting in net decreases in ecosystem productivity. We show that, in contrast to tropical systems, temperate forest edges exhibit increased forest growth and biomass with no change in total mortality relative to the forest interior. We analyze >48,000 forest inventory plots across the north-eastern US using a quasi-experimental matching design. At forest edges adjacent to anthropogenic land covers, we report increases of 36.3% and 24.1% in forest growth and biomass, respectively. Inclusion of edge …

Advanced Science Research Center

Ecosystems across the United States are changing in complex ways that are difficult to predict. Coordinated long-term research and analysis are required to assess how these changes will affect a diverse array of ecosystem services. This paper is part of a series that is a product of a synthesis effort of the U.S. National Science Foundation’s Long Term Ecological Research (LTER) network. This effort revealed that each LTER site had at least one compelling scientific case study about “what their site would look like” in 50 or 100 yr. As the site results were prepared, themes emerged, and the case …

Applying A Novel Systems Approach To Address Systemic Environmental Injustices: Constructing Soil For Limiting The Legacy Of Lead (Pb), Sara Perl Egendorf, Peter M. Groffman, Zhongqi Cheng, Michael Menser, Jan Mun, Howard Mielke

Advanced Science Research Center

The knowledge of unsustainable human and Earth system interactions is widespread, especially in light of systemic environmental injustices. Systems science has enabled complex and rigorous understandings of human and Earth system dynamics, particularly relating to pollution of Earth’s land, water, air, and organisms. Given that many of these systems are not functioning sustainably or optimally, how might this field enable both rigorous understanding of the issues and experiments aimed at alternative outcomes? Here, we put forth a novel, multiscale systems science approach with three steps: (1) understanding the systemic issues at hand, (2) identifying systemic interventions, and (3) applying experiments …

Synaptic Processes And Immune-Related Pathways Implicated In Tourette Syndrome, Douglas W. Woods

Psychology Faculty Research and Publications

Tourette syndrome (TS) is a neuropsychiatric disorder of complex genetic architecture involving multiple interacting genes. Here, we sought to elucidate the pathways that underlie the neurobiology of the disorder through genome-wide analysis. We analyzed genome-wide genotypic data of 3581 individuals with TS and 7682 ancestry-matched controls and investigated associations of TS with sets of genes that are expressed in particular cell types and operate in specific neuronal and glial functions. We employed a self-contained, set-based association method (SBA) as well as a competitive gene set method (MAGMA) using individual-level genotype data to perform a comprehensive investigation of the biological background …

Voice As A Tool For Learning: Using Personal Narratives To Eliminate Boundaries, Alexandra Reyes

Middle Grades & Secondary Education: Faculty Presentations (1999-2023)

In educational linguistics, educators rely on social interactions and real-world experiences to inform pedagogical practice. Such hands-on learning opportunities are not always accessible to students, due to a variety of external factors. Narratives have long been used as tools for teaching and learning in various contexts, particularly when field experiences are unavailable or unfeasible. Personal narratives can be especially powerful, as they provide insight to others’ lived experiences and transcend cultural, geographic, historical, generational, and linguistic worlds. In this presentation I explore the use of written and video personal narratives as a meaningful supplement to (and potential substitute for) field …

Functional Seizures Are Not Less Important Than Epilepsy, A A Asadi-Pooya, Francesco Brigo, Benjamin Tolchin, Kette D. Valente

Department of Neurology Faculty Papers

Functional seizures (FS) are frequently encountered in neurology clinics, often affect young adults, and have significant negative impacts on many aspects of a person's life. In the current narrative review, we searched the literature regarding some of the consequences of FS (i.e., psychiatric comorbidities, social consequences, costs that are associated with the condition, cognitive impairment in patients with FS, the quality of life of the people with FS, and the increased risk of mortality that is associated with FS). Evidence shows that FS have significant negative consequences, comparable in their magnitude to those affecting patients with epilepsy. The clinical and …

Navigating The Wreck: Writing Women’S Experience Of The Japanese Occupation Of Singapore. Salvaged From The Wreck: A Novel -And- Diving Into The Wreck: A Critical Essay, Dawn Nora Crabb

Theses: Doctorates and Masters

This thesis is in two parts. The first and major part consists of a historical novel followed, in part two, by an essay. The title of this thesis, “Navigating the Wreck”, refers metaphorically to the Fall of Singapore in 1942, the ensuing human tragedy unleashed on the people of Singapore and Malaya, and the literary and historical processes of exploring, interpreting and depicting the past. The Japanese occupation of Singapore has, to date, been described mostly by Western historians and former prisoners of war who have forged a predominant patriarchal narrative. In that narrative—despite the all-encompassing nature of the occupation …

Factors Associated With Intimate Partner Homicide In A West Australian Context, William Anthony Thompson

Theses: Doctorates and Masters

Domestic Violence (DV) is prevalent within Australian society with one in four women experiencing some form ofDV (ABS 2017) in their life. The Australian homicide rate is about 250 deaths per year, of which 52% are domestic related (Virueda & Payne 2010). Domestic homicides include Intimate Partner Homicide (IPH), where the victim and offender shared, or formerly shared an intimate relationship (for example married, defacto and ex partners; Bryant & Cussen 2015). This study analysed the factors of West Australian (WA) IPHs from 2012-2017 inclusive. The aim was to identify aetiologies of IPH offending across ethnicity and gender to understand …

What Boosts? What Drags? A Study Of Teacher Views About The Halt Certification Process Provided By The Australian Professional Standards For Teachers, John Cole

Theses: Doctorates and Masters

The Australian Institute for Teaching and School Leadership (AITSL) has offered certification for teacher career progression to Highly Accomplished and Lead teacher status since 2012. By 2020, about 800 teachers (from an Australian teacher workforce of 300,000) had achieved certification. At the same time, AITSL leadership has advocated for a HALT in every school – which would require 10,000 certified teachers. This research examines the views of teachers from one education sector, in one Australian territory, regarding teacher certification. This research identifies major factors encouraging these teachers to consider certification; drag factors encountered by the teachers during their consideration of …

Headteachers In Difficult Circumstances: A Study Of School Leaders In Post-Conflict, Post-Disaster Nepal, Rupak Dahal

Theses: Doctorates and Masters

School leadership in developing countries, with a particular focus on post-conflict and post-disaster, is an area of increasing importance to education researchers. However, this research has often been limited to the areas of educational achievement and outcomes, government policies and their impact on school systems, and comparing schools irrespective of their vastly different contexts.

This thesis reports on research into school leadership within Nepali government secondary schools, typically referred to as community schools. As a developing country, The Federal Democratic Republic of Nepal (Nepal), faces crucial educational challenges due to its cultural, ethnic, linguistic, and religious diversity, and associated socio-economic …

Antibiotic-Driven Intestinal Dysbiosis In Pediatric Short Bowel Syndrome Is Associated With Persistently Altered Microbiome Functions And Gut-Derived Bloodstream Infections, Robert Thänert, Anna Thänert, Jocelyn Ou, Adam Bajinting, Carey-Ann D Burnham, Holly J Engelstad, Maria E Tecos, I Malick Ndao, Carla Hall-Moore, Colleen Rouggly-Nickless, Mike A Carl, Deborah C Rubin, Nicholas O Davidson, Phillip I Tarr, Barbara B Warner, Gautam Dantas, Brad W Warner

Open Access Publications

Surgical removal of the intestine, lifesaving in catastrophic gastrointestinal disorders of infancy, can result in a form of intestinal failure known as short bowel syndrome (SBS). Bloodstream infections (BSIs) are a major challenge in pediatric SBS management. BSIs require frequent antibiotic therapy, with ill-defined consequences for the gut microbiome and childhood health. Here, we combine serial stool collection, shotgun metagenomic sequencing, multivariate statistics and genome-resolved strain-tracking in a cohort of 19 patients with surgically-induced SBS to show that antibiotic-driven intestinal dysbiosis in SBS enriches for persistent intestinal colonization with BSI causative pathogens in SBS. Comparing the gut microbiome composition of …

Race Youth In Twentieth-Century American Literature And Culture, Claire E. Lenviel

Theses and Dissertations--English

Race Youth in Twentieth-Century American Literature and Culture argues for the centrality of black youth, both real and literary, to the trajectories of African American literature and its repudiation of white supremacy. Drawing on research into the rise of the adolescent and teenager as distinct social categories, I argue that age-based subjectivity should inform how we read race-based subjectivity. My first chapter explores how early twentieth-century black periodicals push back against white supremacist theories of human development in an explicit appeal to what I call “race youth,” the children and adolescents who would take up the mantle of racial uplift. …

Anti-Modalities, David E. Pozen, Adam Samaha

Faculty Scholarship

Constitutional argument runs on the rails of “modalities.” These are the accepted categories of reasoning used to make claims about the content of supreme law. Some of the modalities, such as ethical and prudential arguments, seem strikingly open ended at first sight. Their contours come into clearer view, however, when we attend to the kinds of claims that are not made by constitutional interpreters – the analytical and rhetorical moves that are familiar in debates over public policy and political morality but are considered out of bounds in debates over constitutional meaning. In this Article, we seek to identify the …

Towards A Law Of Inclusive Planning: A Response To “Fair Housing For A Non-Sexist City”, Olatunde C.A. Johnson

Faculty Scholarship

Noah Kazis’s important article, Fair Housing for a Non-sexist City, shows how law shapes the contours of neighborhoods and embeds forms of inequality, and how fair housing law can provide a remedy. Kazis surfaces two dimensions of housing that generate inequality and that are sometimes invisible. Kazis highlights the role of planning and design rules – the seemingly identity-neutral zoning, code enforcement, and land-use decisions that act as a form of law. Kazis also reveals how gendered norms underlie those rules and policies. These aspects of Kazis’s project link to commentary on the often invisible, gendered norms that shape …

Mine The Gap: Using Racial Disparities To Expose And Eradicate Racism, James S. Liebman, Kayla C. Butler, Ian Buksunski

Faculty Scholarship

For decades, lawyers and legal scholars have disagreed over how much resource redistribution to expect from federal courts and Congress in satisfaction of the Fourteenth Amendment's promise of equal protection. Of particular importance to this debate and to the nation given its kaleidoscopic history of inequality, is the question of racial redistribution of resources. A key dimension of that question is whether to accept the Supreme Court's limitation of equal protection to public actors' disparate treatment of members of different races or instead demand constitutional remedies for the racially disparate impact of public action.

For a substantial segment of the …
