Assessment And Monitoring Of Deltaic Wetlands And Fluvial Systems: Refining And Validating A Multimetric Index Of Resaca Ecosystem Health, David Lecusay Jr.

Theses and Dissertations

Resacas are ancient distributary channels of the lower Rio Grande River historically serving as floodwater drainage pathways onto the Laguna Madre, Texas. Resacas provide numerous ecosystem services and critical habitat for many species. Mainly influenced by urbanization, integrating a multimetric index for assessing and monitoring resaca ecosystem health is required for adaptive management. The Resaca Health Index (RHI) integrates structural and functional components: (1) nonredundant metrics describing fish communities (Fish Community Index); (2) Trophic State Index derived from Secchi depth; (3) decay constant from riparian vegetation leaf litter decomposing in the water column; and (4) a riparian quality index based …

The Model Of Development Of Precarious Practices During Covid-19 Pandemic: Society, Religion, And Individual, Оlena Honcharova, Valentyna Kuryliak

Occasional Papers on Religion in Eastern Europe

The article examines the phenomenon of precariousness and its development in the context of the COVID-19 pandemic. It is postulated that precariousness is a process of instability, which primarily affects the working class and destabilizes social relations at all levels, including the level of personal relationships. The human way of life has been shifted as a result of the epidemiological situation in the world caused by the COVID-19 infection. This process can be observed in the spheres of employment, medicine, religion, family, leisure activities, etc. Against the background of social turbulence, the processes of precariousness began to develop, which worsen …

Through A Glass, Darkly: Systemic Racism, Affirmative Action, And Disproportionate Minority Contact, Robin Walker Sterling

Michigan Law Review

This Article is the first to describe how systemic racism persists in a society that openly denounces racism and racist behaviors, using affirmative action and disproportionate minority contact as contrasting examples. Affirmative action and disproportionate minority contact are two sides of the same coin. Far from being distinct, these two social institutions function as two sides of the same ideology, sharing a common historical nucleus rooted in the mythologies that sustained chattel slavery in the United States. The effects of these narratives continue to operate in race-related jurisprudence and in the criminal legal system, sending normative messages about race and …

Young And Dangerous: The Role Of Youth In Risk Assessment Instruments, Ingrid Yin

Michigan Law Review

States are increasingly adopting risk assessment instruments (RAIs) to help judges determine the appropriate type and length of punishment for an offender. Although this sentencing practice has been met with a wide variety of scholarly criticism, there has been virtually no discussion of how RAIs treat youth as a strong factor contributing to a high risk score. This silence is puzzling. Not only is youth undoubtedly the most powerful risk factor in most RAIs, but youth also holds a special place in the criminal justice system as a “mitigating factor of great weight.” This Comment presents the first in-depth critique …

The goal of that LCA is to determine “environmental impacts of implementing electrochemical struvite recovery at the wastewater treatment plant, U.S watershed, and global scales” (Morrissey 2019). This project’s goal is to identify locations deemed more sensitive to eutrophication impacts. The results will be used as part of the life cycle inventory (LCI) accounting for geographically explicit phosphorus flows. The waters identified as impaired were sourced from the …

How The Value Of The Environment Controls Persistence In Visual Search, Michael R. Traner, Ethan S. Bromberg-Martin, Ilya E. Monosov

Open Access Publications

Classic foraging theory predicts that humans and animals aim to gain maximum reward per unit time. However, in standard instrumental conditioning tasks individuals adopt an apparently suboptimal strategy: they respond slowly when the expected value is low. This reward-related bias is often explained as reduced motivation in response to low rewards. Here we present evidence this behavior is associated with a complementary increased motivation to search the environment for alternatives. We trained monkeys to search for reward-related visual targets in environments with different values. We found that the reward-related bias scaled with environment value, was consistent with persistent searching after …

Neutrophil Extracellular Trap Inhibition Increases Inflammation, Bacteraemia And Mortality In Murine Necrotizing Enterocolitis, Hala Chaaban, Kathryn Burge, Jeffrey Eckert, Ravi S Keshari, Robert Silasi, Cristina Lupu, Barbara Warner, Marilyn Escobedo, Michael Caplan, Florea Lupu

Open Access Publications

Necrotizing enterocolitis (NEC) is a devastating gastrointestinal disease affecting primarily premature infants. The disease is characterized by intestinal inflammation and leucocyte infiltration, often progressing to necrosis, perforation, systemic inflammatory response and death. Neutrophil extracellular traps (NETs), denoting nuclear DNA, histone and antimicrobial protein release, have been suggested to play a role in NEC. This study aimed to determine the role of NETs in NEC and explore the effect of chloramidine, a NET inhibitor, on a murine NEC-like intestinal injury model. Blood and intestinal tissues were collected from infants diagnosed with ≥ Stage II NEC, and levels of nucleosomes and NETs, …

Writing Black Characters Out Of The Margins Of Fantasy With Secrets Of Candeo, Julienne Parks

Electronic Theses, Projects, and Dissertations

The crawling pace that the production of diverse fantasy books has set for itself continues to reveal that Black characters and the representation of Blackness in fiction is lacking in a detrimental way. Specifically speaking, this thesis focuses on the prevalent lack of Black characters in the fantasy genre, where Black people are cast as minor characters to a white protagonist’s story like Angela Johnson from Harry Potter; cast as abominations of anti-Black stereotypes in monsters like the Uruk-hai of Lord of the Rings; and cast as side(kick) characters like Vetch from Earthsea, aka Black characters who are …

Exploring Teacher And Student Experiences In A Nature-Based Mathematical Environment, Brian Holt Tucker

Dissertations

This research study explored the experiences of this teacher-researcher and eight student-participants in a Montessori-inspired, nature-based mathematical environment. I utilized an action research study framework with a critical event narrative analysis to describe mine and my student-participants’ experiences throughout this study, using Uhrmacher et al.’s (2017) instructional arc as a guide. I restoried each participants’ lived and told stories as the curriculum seamlessly moved through the arc: intended to operational to received curriculum. The restoried narratives revolved around the identified critical events each participant experienced throughout the mathematical learning experience. The multiple restoried narratives required data collection that included observations, …

Becoming Ourselves: A Photo-Narrative Inquiry Into Mindfulness In The Teaching Lives Of Urban Educators, John Brian Miller

Dissertations

This dissertation explored how mindfulness shapes the way educators find meaning and coherence to their narrative selves amid the complex interlocking contexts in urban schools. Drawing on the theoretical lens of a narrative concept of self found in MacIntyre and others, I used a photo-narrative inquiry, observations, and interviews to collect data from the five participants in this study. I then constructed narrative vignettes that highlighted themes internal to each participant’s way of storying their teaching lives in urban schools through the lens of mindfulness. Analysis of participant stories leads to the conclusion that mindfulness is a grounding for self …

Participants were four staff members of Utah’s SHIFT Professional Development program, and four of its teacher participants The study’s data collection included artifacts, an observation, and (primarily) interviews during the first full school year of COVID-19 (Fall, …

Developing And Piloting An E-Learning Module On Respiratory Protection, Emily Girard

Capstone Experience: Master of Public Health

Respiratory diseases are one of the most common causes of occupational illnesses in the United States. Many occupations use personal protective equipment (PPE) in the form of respirators to protect against respiratory hazards when other control methods are not effective. However, some workers may not have had adequate training on their use. An e-learning module was developed to provide information about respirators and their use in agriculture. The interactions of matching, sorting, and review questions require the user to be an active participant with the goal of reinforcing the information. It was hypothesized the average summative assessment score would increase …

Factors Contributing To Trust Of Occupational Healthcare Services In Meatpacking Plants, Gabriella Ochoa

Capstone Experience: Master of Public Health

Meatpacking refers to the slaughtering of livestock and processing and packaging it into meat and other byproducts. Meatpacking is a large industry employing thousands of workers from various racial and socioeconomic backgrounds in Nebraska. These workers have experienced disparities in accessing occupational health services such as language barriers, fear of job loss, or deportation due to immigration status if these services were used. The purpose of this study was to investigate how trust in occupational health services varied among employees at a meatpacking plant in Nebraska by demographic characteristics, particularly by ethnicity, gender, and English language proficiency.

Greenhouse Gas Emissions From Two Contrasting Beef Systems From Birth To Slaughter In Eastern Nebraska, Levi J. Mcphillips

Department of Animal Science: Dissertations, Theses, and Student Research

Over the last 15 years, the increase in land use for corn and soybean has come at the expense of acres of grasslands and perennial forages employed in conventional beef-production systems. Implementing alternative cow-calf production systems into existing cropping systems may be a solution for reduced land availability and reducing total greenhouse gas emissions (GHG). Therefore, GHG from a conventional (CONV) pasture-based cattle production system with cows wintered on corn residue and summer grazing of brome pasture were compared to partial-confinement system (ALT) with cows and calves in a drylot during the summer and grazing cover crops and corn residue …

Small Grain Cereal Cover Crops For Late Fall Or Early Spring Grazing, Kallie J. Calus

Department of Animal Science: Dissertations, Theses, and Student Research

Beef cattle operations are confronted with early spring and late fall forage deficiencies. Producers in integrated crop and livestock systems can fill forage gaps using cover crops as a forage source in between cash crops.

A five-year study evaluating forage production, growing calf performance and economics of grazing an oats cover crop planted after corn silage (CS) and high moisture corn (HMC) corn harvests was conducted. The economic analysis accounted for costs of establishing and grazing the oats and the value of calf gain to determine fall grazing system profitability. Steers had greater average daily gain grazing oats after CS …

Management Of Late Summer Planted Annual Forages For Grazing And The Impacts Of Novel Sweet Bran Plus Products On Performance And Carcass Characteristics Of Beef Finishing Steers, Devin Anthony Jakub

Department of Animal Science: Dissertations, Theses, and Student Research

Two separate grazing studies were conducted to evaluate: 1) the effects of rapeseed inclusion into late summer planted oats on the performance of growing steers during late fall and winter (Exp. 1) and 2) the effects of forage allocation on forage utilization and performance of steers grazing a late summer planted oat-rapeseed mix (Exp. 2). Variation in the corn wet milling process can result in negative effects on animal performance, nonetheless, there remains interest in further exploration and refinement of corn wet milling byproducts to achieve optimal byproduct compositions and cattle performance. Thus, another experiment was conducted to evaluate the …

Impact Of Wood-Sourced Biochar On Carbon And Nitrogen Capture In Beef Feedlot Systems, Jessica L. Sperber

Department of Animal Science: Dissertations, Theses, and Student Research

A feedlot growing and finishing experiment evaluated the effect of including pine-sourced biochar at 0.8 (growing) and 1.0% (finishing) of dietary DM on steer performance, carcass characteristics, and greenhouse gas (GHG) production (Exp 1). Two nutrient mass balance experiments were conducted during winter and summer seasons to evaluate the effect of spreading unprocessed red cedar biochar on the feedlot pen surface on manure nutrient capture and cattle performance (Exp 2). In Exp. 1, the inclusion of biochar in the growing diet did not impact steer performance. The inclusion of biochar in the finishing diet significantly reduced intake and gain, resulting …

Department of Animal Science: Dissertations, Theses, and Student Research

In recent years, the shift toward online education has revealed new challenges for learners to retain information, and for educators to find new and engaging ways to present content. This mixed methods, action research study explores the need and creation of online resources for competitive horse judging through surveys and pilot groups. The study was broken into four cycles. The first was an adult learner analysis survey, distributed through email Listservs and extension social media pages, to aid in answering the research questions: what expert horse judging instructors indicate their students should be learning, and what resources they need. Based …

Evaluation Of Cattle Management For Systems With Limited Perennial Pasture, Morgan Grabau

Department of Animal Science: Dissertations, Theses, and Student Research

Due to the conversion of perennial pasture and hay land to cropland in the western corn belt region, alternative methods of cow/calf management are being used to decrease reliance on perennial forages. These include grazing corn residue and feeding cow/calf pairs in confinement. Previous research has shown that limit-feeding a diet of low-quality forage and energy-dense co-products to cows in confinement is cost-effective. However, this strategy may limit the intake of the young calf and thus their performance. A study was conducted to evaluate the impacts of two alternative calf management strategies when pairs are in confinement, early weaning or …

An Increase In Racism During The Covid-19 Pandemic And The Ontology Of Race: Intercultural Comparison Of The European And Chinese Traditions, Jana S. Rošker

Economic and Business Review

The article treats intercultural problems of global-scale crises, focusing upon the pandemic of the viral disease COVID-19. It deals with the question of whether racism is universal or culturally conditioned, and shows that it is an ideological inheritance of the ontological status of the concept of race, which was developed and established in the context of the European ideational tradition. By presenting traditional Chinese models of relational and anti-essentialist concepts of the self, the article aims to point to new possibilities of understanding interpersonal and intercultural interactions that can help us to develop new strategies against the pandemic.

Characterizing Plasmids In Bacteria Species Relevant To Urinary Health, Cesar Montelongo Hernandez, Catherine Putonti, Alan J. Wolfe

Biology: Faculty Publications and Other Works

The urinary tract has a microbial community (the urinary microbiota or urobiota) that has been associated with human health. Whole genome sequencing of bacteria is a powerful tool, allowing investigation of the genomic content of the urobiota, also called the urinary microbiome (urobiome). Bacterial plasmids are a significant component of the urobiome yet are understudied. Because plasmids can be vectors and reservoirs for clinically relevant traits, they are important for urobiota dynamics and thus may have relevance to urinary health. In this project, we sought plasmids in 11 clinically relevant urinary species: Aerococcus urinae, Corynebacterium amycolatum, Enterococcus faecalis, Escherichia coli, …

Effects Of Static And Dynamic Visuals On The Learning Of Science Concepts In The Secondary-School Classroom, Theodore Johnson
