Studies On Molecular And Morphological Evolution And Biogeography Of Squids, Abigail M. Pratt

Dissertations

The cephalopod clade Decapodiformes consists of Spirulida (ram’s horn squid), Sepiolida (bobtail squids), Sepiida (cuttlefishes), Myopsida (inshore squids), and Oegopsida (oceanic squids). While many unanswered questions remain regarding this clade, a thorough examination requires a multi-level taxonomic approach due to uneven data coverage within. This dissertation explores a diverse set of topics in decapodiform evolution and biogeography with a hierarchical approach, starting with the “superorder” Decapodiformes, moving to the “order” Oegopsida, and finally zooming in to the family level with Pyroteuthidae. addressing four main questions: 1) Does RNA editing affect the use of transcriptomics in cephalopod phylogenetics? 2) What is …

Impact Of Foreign Aid To Agriculture In Reducing Poverty In Developing Countries., Richard Amoako

Theses

The effectiveness of foreign aid in reducing poverty has been a contentious issue in development economics. This paper focuses specifically on aid directed towards agriculture, a sector critical for rural livelihoods and poverty alleviation. It investigates the empirical relationship between agricultural aid flows and poverty levels in 46 developing countries between 1997-2020. Fixed effects panel regressions estimate models with the $2.15/day (based on 2017 PPP) poverty headcount ratio as the outcome variable. The key finding is that agricultural aid has a statistically significant poverty-reducing impact. The regression coefficients indicate that on average, a 1% increase in agricultural aid is associated …

Effects Of Urban Borders On Synanthropic Mesopredator Movement And Risk Of Toxoplasma Gondii Infection In The Protected Lands Of Key Largo, Florida Usa, Kelly A. Crandall

Theses

Protected lands are an important source of food, shelter, and reproductive opportunities for wildlife, especially in urbanizing landscapes. When urban development abuts the edges of protected lands, synanthropic species can alter their foraging behaviors and movement to utilize human-supplemented resources throughout the urban-wild interface. Therefore, urban edges on protected lands can have pronounced effects on animal movement and ecosystem function. There is also increased risk of disease transmission where high densities of wild animals exist, or where domestic animals and wild species are interacting. In particular, members of the family Felidae, including domestic cats (Felis catus), can transmit the pathogenic …

Impacts Of Intensifying A Corn-Soybean Rotation With Winter Wheat (Triticum Aestivum) On Nutrient Leaching, Plant Available Nutrients, Crop Yields, And Nitrogen Dynamics In Southern Illinois, Abigail Leigh Spiers

Theses

The Midwestern United States is a nationally and globally important producer of agricultural products and uses intensive practices to achieve high grain yields. However, intensive agriculture is a major contributor of nitrogen and phosphorus export to the Mississippi River and the hypoxic zone in the Gulf of Mexico. Cover cropping is a recommended conservation practice for providing soil cover throughout the winter and taking up nutrients that may otherwise be lost in bare fallow systems, but the associated costs limit widespread adoption of this practice. Double cropping, which involves growing two crops in one year, is functionally similar to cover …

Essays On The Effects Of Resource Wealth And Us Influence On Employment, Education And Export Structure, Lyndrison Garthfield Lincoln

Dissertations

Although several studies have sought to identify the determinants of export diversity and sophistication, few have examined the role of historical events in shaping or reshaping them. In my first chapter I use data on CIA interventions during the Cold War period. I show that such interventions had a negative impact on the range of goods exported by affected countries. I provide evidence that this effect persisted in the long run. In my second chapter, I study the local impact of trade union strength on employment during resource booms. I use unionization and coverage rates along with the presence of …

Microglial Piezo1 Mechanosensitive Channel As A Therapeutic Target In Alzheimer's Disease, Erol D Ikiz, Erin R Hascup, Chilman Bae, Kevin N Hascup

Articles

Microglia are the resident macrophages of the central nervous system (CNS) that control brain development, maintain neural environments, respond to injuries, and regulate neuroinflammation. Despite their significant impact on various physiological and pathological processes across mammalian biology, there remains a notable gap in our understanding of how microglia perceive and transmit mechanical signals in both normal and diseased states. Recent studies have revealed that microglia possess the ability to detect changes in the mechanical properties of their environment, such as alterations in stiffness or pressure. These changes may occur during development, aging, or in pathological conditions such as trauma or …

Of the 30 PFAS monitored in this study, 14 were detected in the samples in various combinations. Short-chain PFAS (less than 8 carbon atoms) were observed in most samples. Water collected from the Arroyo Colorado showed significant spatial variabilities, with high total PFAS concentrations observed near possible point sources - a …

Matrix Training For Expanding The Communication Of Toddlers And Preschoolers With Autism Spectrum Disorder, Jacy Durdel, Maggie Ratcliff

Honors Theses

Children diagnosed with autism spectrum disorder (ASD) commonly display a range of deficits from communication skills to play skills. When the ability to generalize is improved, a greater number of stimuli can be learned without having to be directly taught, which can be done through matrix training. Matrix training provides a framework for actively teaching a singular exemplar of a target, and, through recombination, many more stimuli can be learned. Participant is a 4-year-old boy diagnosed with ASD who was taught noun-verb combinations through tactile movement of figurines. All targets are tested before and after the single stimulus of each …

The Practical Application Of In-Vitro Tissue Digestion As A Means Of Producing Species-Specific Larval Diets And The Impact Of Dietary Protein Composition On Growth And Metabolism In Freshwater Fish, Giovanni Settle Molinari

Dissertations

The heavy reliance on live feeds is currently restricting the growth and sustainability of the aquaculture industry, therefore, the overall goal of this research was to improve the utilization of formulated dry diets at first feeding of larval fish. This was done with a specific focus on the production and provision of the optimal dietary protein form and composition. Chapter 2 aimed to provide an efficient protein source for larval fish by using same-species muscle and endogenous enzymes to produce hydrolysates and by providing a series of diets with increasing molecular weight protein fragments through larval development. Largemouth Bass (Micropterus …

The Effect Of Altitude On Decomposition: Toward An Understanding Of The Postmortem Interval In The Rocky Mountain Region Of Colorado., Christiane Irene Baigent

Dissertations

The estimation of postmortem interval (PMI) is a critical component of medicolegal death investigation. An accurate PMI estimate has the potential to influence the allocation of investigative resources, establish the probative value of associated biological and material evidence, shape the analytical framework applied to skeletal analysis, and inform cause and manner of death. Forensic anthropologists are often tasked with PMI estimation throughout all stages of decomposition and typically rely on categorical phases of soft tissue and skeletal change purported to correspond to broad estimates of elapsed time. In an attempt to improve precision, Megyesi et al. (2005) developed the Total …

Selenate-Mediated Impacts On Mercury Methylation By Pseudodesulfovibrio Mercurii With Dissolved And Nanoparticulate Mercuric Nitrate, Md Sayeduzzaman Sarker

Theses

Inorganic mercury (Hg) is converted to potential neurotoxic methylmercury (MeHg) by a natural process called Hg methylation. MeHg can be biomagnified in the food chain, thus the consumption of Hg-contaminated fish contributes to harmful human health issues. Selenium (Se) inhibits the Hg bioavailability to the methylating bacteria by forming mercuric selenide (HgSe). Pseudodesulfovibrio mercurii, a type of sulfate-reducing bacteria (SRB) cultures were grown in anaerobic environments using an estuarine sulfate lactate growth medium to evaluate the effects of Hg concentrations, bacterial growth phase, and sodium selenate in the Hg methylation process. Bacterial cultures contained two types of mercuric (II) nitrate, …

The objective of this research was to evaluate the impact of strategical blending of by-products of pea protein extraction such as pea molasses (PMS) and pea starch and fiber (PSF) with canola meal (CM) or distillers dried grains (DDGS) on the growth performance, rumen fermentation, and total tract nutrient digestibility of beef cattle. Preliminary evaluation (study 1) involved 4 runs of in vitro and two runs of in situ to evaluate the rumen fermentation and nutrient degradation of strategically blended CM. The treatments included regular CM (CM), CM blends containing PMS and PSF at 5% (CM5) and 10% (CM10) levels …

Investigating Native Bamboo Practices For Reservoir Conservation And Habitat Restoration, Taryn Elizabeth Ann Bieri

Theses

Reservoirs are an important resource for both humans and wildlife. They provide drinking water, recreational opportunities, wildlife habitat and more. A major issue land managers face on reservoirs is shoreline erosion leading to water quality impairments, sedimentation, and habitat loss. Traditionally, riprap has been used to mitigate this issue, but is costly and has limited ability to provide habitat. A promising measure to mitigate shoreline erosion and provide habitat is the establishment of giant cane [Arundinaria gigantea (Walt.) Muhl], on shorelines. Giant cane, a bamboo species native to southern Illinois and the southeastern United States, forms monodominant stands called canebrakes. …

Despite the variety of research conducted on this species for nearly a century, populations continue to steadily decline, raising concern for future populations and highlighting the need for region-specific research. My research was conducted at Burning Star State Fish and Wildlife Area in northeastern Jackson County, Illinois from 2020-2022. My research addressed the following two objectives to provide insight on the population ecology of bobwhites at this site: (1) investigate the impact of multiple woody cover types within the home ranges …

The Impact Of Vehicular Noise On The Effectiveness Of Acoustic Indices, Rebecca Ducay

Theses

Passive acoustic monitoring (PAM) is a valuable tool in wildlife research, offering non-invasive and cost-effective means to collect acoustic data. However, the processing of PAM recordings can be time-consuming, prompting the use of acoustic indices to expedite analysis. Acoustic indices are numerical values that characterize biological information in sound recordings based on an environment’s acoustic characteristics. While acoustic indices have been correlated with species richness across ecological contexts, their reliability diminishes in areas with heightened vehicular noise. However, it is unclear if index biases caused by vehicular noise are consistent across all traffic levels, and which acoustic indices are most …

Neural Activation Patterns During Socially Transmitted Aggression, Elana Qasem

2024

Children who experience abuse or witness it are at an elevated risk of becoming either victims themselves or engaging in violent behavior later in life, possibly due to the observed behavior of the abuser or the abused. However, socially transmitted aggression remains understudied due to the absence of a suitable behavioral paradigm. This study addresses this gap by introducing a novel social transmission paradigm combined with fiber photometry to explore the brain regions implicated in socially transmitted aggression in mice, given the conservation of their circuity and impact on aggressive behavior. This study addresses this gap by introducing a novel …

The Effect Of Covid-19 Pandemic On U.S. Beef Exports To Its Major Trading Partners, Richard Bien

Research Papers

This study analyzed the effect of COVID-19 on U.S. beef exports to South Korea, Japan, China, Mexico, and Canada between June 2017 and July 2023. After accounting for potential factors influencing exports, the study finds that the pandemic’s impact was different in both magnitude and persistence among major trading partners. The drop in exports to Japan and Mexico were notable during the pandemic. The decline in exports began early in the year for Mexico and in March for South Korea. Exports to Canada on the other hand both increased and decreased during this period. Exports to China followed a different …

Retention In Research Administration, Kelly Alongi

Ed.D. Capstone Reports

The current study was conducted to gain insight into what factors are most important to research administrators when they are deciding whether to remain at or leave their current organization. Research administration, like many other professions, experiences a high rate of turnover. This is problematic because the time to train research administrators can be very lengthy and expensive. This exploratory study utilized a quantitative survey to find the most highly rated factors by research administrators when deciding whether to stay at or leave their position.

Teaching Philosophy As A Pedagogic Practice-Ing: Are You The Type Of Person That Says, “Everything Happens For A Reason”?, Valerie Oved Giovanini Ph.D.

Artizein: Arts and Teaching Journal

In this paper, I discuss a classroom activity that was intended to create an environment attentive enough for students to scrutinize whether their touted beliefs matched their implicit assumptions. Drawing upon Emmanuel Levinas’s ethics of the face-to-face relation, Carol A. Taylor’s posthuman orientations for pedagogical practice-ings, and Bickel’s and Fisher’s emergent theory of art-care, I explore my pedagogical approach in teaching philosophy to explain how affective encounters in communitas between teacher and learners can expand personal understandings and imagine new meaningful possibilities together. These affective encounters serve an ethic of concern where each is capable of a unique response and …
