The Black Ceiling: The Underrepresentation Of African American Females In The Ces Professorate, Sharon Vanessa Lewis

Doctoral Dissertations and Projects

This qualitative phenomenological study highlighted the lived experiences of six African American female professors in the counseling education and supervision professorate. The professors were faculty within universities across the United States in the mid-Atlantic, southern, and midwestern regions. This study obtained data from semi-structured interviews as well as photovoice submissions from the interview participants in order to identify experiences which facilitated their persistence in the professorate and overcoming internal and external barriers. The research problem was the underrepresentation of African American females within the counseling education and supervision professorate, which further facilitates minority students’ attrition and underrepresentation. A thematic analysis …

The Jewish Origins Of The Ordinances Of Christianity: Worship Within Baptism And The Lord's Supper, John Edward Ross

Doctoral Dissertations and Projects

The modern evangelical denominations have worship services that include many forms of worship and functions to bring the worshiper into communion with the living God as a disciple of Christ. These worship forms include the two ordinances of baptism and the Lord’s Supper. Generations of denominational congregants have participated in these ordinances with little knowledge of the origin of these two rites. This qualitative historical study focuses on the roots of the ordinances of baptism and the Lord’s Supper formed within Christianity during the early church years. Using research from Christian and Messianic Jewish scholars along with Jewish sources, this …

Folk Physics In The Twenty-First Century: Understanding Tooling As Embodied, Dorothy M. Fragaszy, Madhur Mangalam

Journal Articles

Povinelli’s (2000) studies with chimpanzees (Pan troglodytes) reported in “Folk Physics for Apes” were firmly grounded in a Cartesian view of knowledge, which posits that humans use abstract concepts such as force, gravity, and shape to reason causally about events and plan our actions (with tools in the case of Folk Physics for Apes). Povinelli set out to examine if chimpanzees, like humans, used causal concepts to solve mechanical problems, as the Cartesian view predicts. However, Povinelli’s findings uniformly challenged his expectations. Povinelli’s book stimulated research and contributed to the development of alternate understandings of how animals (including humans) use …

Nutraceutical Potential For Alzheimer's Disease Treatment, Alex Gewecke

Undergraduate Research Journal

Alzheimer’s disease (AD) is a progressive disorder involving buildup of excessive amounts of proteins such as beta amyloid in the brain that leads to memory loss, inability to perform daily functions, and an early death. By 2060, the number of cases is forecast to nearly triple current numbers. Age is the primary risk factor for AD and no new drugs have been approved since 2003. Nutraceuticals, a broad category of substances that can be utilized for both medicinal and nutritional purposes may be able to help, which is why they are being more widely researched. Overall, a number of attempts …

Using Speech Screening Process For Preschool-Age Children: Do Results Lead To Action?, Autumn Rhoads

Undergraduate Research Journal

In this paper, we will discuss the concerns of a microstrip two patch antenna system. Coupling of the two-port system can be miniaturized using Electromagnetic Bandgap Structures (EBG) or Defected Ground Structures (DGS) centered between the two patch antennas half a wavelength in size. Different miniaturization methods were used in the design of the antenna system to change the properties of the signal. Changing via locations that are not found on EBG strips themselves, rather found on interleaved ledges between EBG strips allowed for further change in shifting the signals frequency.

The Conservation Treatment Of A 19th-Century Scottish Pastel On Paper, Perrine Le Saux

Art Conservation Master's Projects

A framed 19th century Scottish pastel portrait on paper, severely damaged after a fall, was admitted to the Garman Art Conservation Department at Buffalo State College for examination, research, and treatment. Conservation photography helped in documenting and understanding the extent of the damage. Research helped to reinforce the attribution of the drawing to Sir Daniel MacNee and to learn more about the man in the portrait: Robert Maxwell Jr. The drawing was torn significantly in its wood strainer as a result of the original glazing breaking and has suffered loss of media due in part to abrasion. The support …

Life History And Metabolic Responses Of Daphnia Magna Exposed To Effluents Of Urban Origin Treated By Advanced Oxidation, Benjamin Z. Szczygiel

Biology Theses

Modern sewage treatment processes do not remove many chemicals that pass through the sewer system, including pharmaceuticals and personal care products that have been shown to have negative effects in ecosystems. New processes have been developed to remove these chemicals, known as advanced oxidation processes (AOPs). In this study, Daphnia magna are used to examine the effects of wastewater effluent treated conventionally compared to effluent treated with AOPs (Peracetic Acid/Ultraviolet Light and Hydrogen Peroxide/Ultraviolet Light). For this purpose, two sets of experiments were preformed: a five-day survivorship trial, and a 14-day life history experiment. Growth, survival, and reproduction of Daphnia …

Impacts Of The Degraded Alpine Swamp Meadow On Tensile Strength Of Riverbank: A Case Study Of The Upper Yellow River, Peng Gao, Haili Zhu, Zhiwei Li, Jiangtao Fu, Guorong Li, Yabin Liu, Xilai Li, Xiasong Hu

Geography and the Environment - All Scholarship

In the meandering riverbank of the Upper Yellow River (UYR), the native alpine swamp meadow (AS) has continuously degenerated into an alpine meadow (AM) due to climate change and intensified grazing. Its implication on river morphology is still not well known. This study examined this effect by in situ measurings of (1) physical properties of roots and their distribution in the soil-root mixture of the upper bank layer, and (2) the tensile strength in terms of excavating tests for triggering cantilever collapses of AS and AM riverbanks. The results showed that the root number in AS was significantly greater than …

Democracy, Deference, And Compromise: Understanding And Reforming Campaign Finance Jurisprudence, Scott P. Bloomberg

Loyola of Los Angeles Law Review

In Citizens United, the Supreme Court interpreted the government’s interest in preventing corruption as being limited to preventing quid pro quo— cash-for-votes—corruption. This narrow interpretation drastically circumscribed legislatures’ abilities to regulate the financing of elections, in turn prompting scholars to propose a number of reforms for broadening the government interest in campaign finance cases. These reforms include urging the Court to recognize a new government interest such as political equality, to adopt a broader understanding of corruption, and to be more deferential to legislatures in defining corruption.

Building upon that body of scholarship, this Article begins with a descriptive …

Yield And Nutritional Composition Of Conventional And Bmr Pearl Millet Under Different Management Conditions, Madeline A. Oskey

All Theses

The main objectives of these studies were to evaluate the yield, composition and digestibility of conventional and BMR pearl millet (PM, Pennisetum glaucum) with different establishment dates or harvested at different maturity stages. A second objective was to evaluate the impact of mixing PM with cowpea on measured variables. Two trials were conducted in field plots (1.5 m x 6.1 m) as randomized complete block designs with a split plot arrangement of treatments. In trial 1, two varieties of PM (conventional and BMR) were planted at two different dates (14d apart) and harvested at early heading stage. In trial …

Spaces In-Between, Sara Mays

All Theses

In his book, The Poetics of Space, French philosopher Gaston Bachelard uses a phenomenological approach in which he explores and muses about objects such as the nest, the shell, and the corner. Through personal observation, his mode of examination is prolonged and generous to those things he observes. For him, those places he explores can be filled with our own thoughts and so, set them apart as spaces made anew. The inside of a shell becomes an entire house and a corner gives way to a whole room.

Habitat Relationships Of Bat Species Of Conservation Concern In Coastal South Carolina, Kyle Edward Shute

All Theses

Loss of forest habitat used for roosting and nocturnal activity by bats is a conservation concern in the southeastern United States. The northern long-eared bat (Myotis septentrionalis), southeastern myotis (Myotis austroriparius), tri-colored bat (Perimyotis subflavus), and northern yellow bat (Lasiurus intermedius) all occur within the Coastal Plain of South Carolina, where their greatest conservation threat is loss of critical roosting and foraging habitats. However, little research has been conducted on these species of conservation concern in this region, leaving gaps in information about habitat associations that would inform conservation and management as forest loss continues due to logging, agriculture, urban …

Enzymatic Targets For Improvement Of Malting Sorghum, Andrew Disharoon

All Theses

Sorghum bicolor (L.) Moench is a climate resilient grain cereal crop originating from Africa that has traditionally been used to make a variety of fermented beverages such as pito and baijiu. In western markets, the use of sorghum to produce beers and beverages has recently risen in part due to the visibility of a gluten sensitive/intolerant market and a growing interest in unique inputs for beverage production. As such, there is a developing body of research on sorghum as a malted input into beverages. A major limitation to the wider adoption of sorghum as a substrate in mashing is its …

Arsenic Exposure Decreases The Number And Signaling Of Distinct Intestinal Stromal Cells, Michael Kellett

All Theses

Arsenic is a natural toxicant commonly found in drinking water. Since its main route of exposure is oral, arsenic is continually in contact with the small intestine. While in vitro arsenic exposures of environmentally relevant concentrations can disrupt differentiation in cardiac and skeletal muscle, neurons, and keratinocytes, little is known of the impact of an in vivo arsenic exposure. Since the epithelium of the small intestine rapidly regenerates, we wanted to investigate whether arsenic alters the balance of renewal and differentiation. Small intestinal organoids (enteroids) were used to assess arsenic’s impact on intestinal homeostasis by exposure to 0, 1, and …

Role Of Cyp2b6 In Perfluorooctanesulfonic Acid (Pfos)-Induced Toxicity And Non Alcoholic Fatty Liver Disease (Nafld), Matthew C. Hamilton

All Theses

Perfluorooctanesulfonic acid (PFOS) is a persistent, toxic fluorosurfactant foam used in firefighting foams, textiles, and other industrial products. Human CYP2B6 is predominantly expressed in the liver and responsible for metabolizing xeno- and endobiotics. CYP2B is induced by PFOS and high-fat diets in rodents and therefore it was hypothesized that CYP2B contributed to PFOS-induced steatosis. Cyp2b-9/10/13-null (Cyp2b-null) and humanized CYP2B6-Tg (hCYP2B6-Tg) mice were treated with PFOS (0, 1, or 10 mg/kg/day) by oral gavage in mice fed either a typical chow diet (ND) or a high-fat diet (HFD). Our studies show human CYP2B6 is also inducible in vivo by PFOS. In …

Rendering Co-Products As Electron Donors For Subsurface Remediation, John K. Houston

All Theses

Chlorinated solvents are a widespread groundwater contaminant across the United States and worldwide. Bioremediation strategies for chlorinated solvents in groundwater environments often involve electron donor amendments to stimulate reductive dechlorination.

Electron donor amendment technologies have evolved over time, utilizing varying lipid or carbohydrate based compounds. Several popular electron donor amendments contain soybean based emulsified vegetable oil (EVO), or low molecular mass organic acid compounds including acetate and formate. This project seeks to develop a group of novel electron donor amendments based on animal co-products to outperform conventional products. These co-products are comprised of waste generated in the animal rendering process …

Improving Hazard Perception And Tracking Through Part-Task Training, Nathan Dumessa

All Theses

Safe driving requires wisely allocating focal attention among multiple changing events and comprehending those events. Research suggests that attentional skills can be improved by training. This study uses a low-fidelity driving simulator to train participants using part-task training on two attentional subskills: identifying (comprehending) and tracking potential hazards; and detecting and avoiding imminent hazards. Following initial familiarization with the driving simulator, each participant received training in one of these two attentional subskills. Hazard tracking probes train (and measure) identifying and tracking potential hazards by having participants watch a moving driving scenario and then select the vehicle that behaved hazardously during …

The Microbiome Of Southwestern Rattlesnakes, Erin Stiers

All Theses

The gut microbiota encompasses the microbial life present in animal digestive tracts, collectively termed the microbiome. These microbial communities are highly adapted to their environment and host, providing beneficial functions not encoded by the host genome. However, there is a lack of gut microbiome studies on wild, non-model organisms; because of the importance of microbiomes in host evolution, it is critical to understand how environment and host alike shape indigenous microbes in wild animal populations. Rattlesnakes (Crotalus and Sistrurus) provide a useful system to study microbiota differences due to their unique digestive process and locally adapted venoms, which function in …

Assessing The Value Of South Carolina’S Coastal And Timber Resources, Andrew Davis Purcell

All Theses

South Carolina is blessed with abundant natural resources that span from the southern edge of the Blue Ridge Mountains, across the Piedmont, and into the coastal plain that borders the Atlantic Ocean. These resources are known to hold tremendous value to the state but are often understudied, leaving little documentation to support the claim of their value. The purpose of this thesis is to identify South Carolina’s coastal natural resources, estimate the economic value of these coastal resources by individual habitat components, and to estimate the effect of timber tax on property inheritance in South Carolina. By doing so, these …

Novel Methods For Rgb Aerial Image Analysis, Brennan Teddy

All Theses

Multiple linear regression models were developed to predict sand and clay content along with soil organic matter content from RGB imagery from both commercially available satellite imagery as well as RGB UAV imagery. UAV Imagery was tested at two flight altitudes to determine if lower or higher altitude had an effect on prediction. In cases of sand, clay, and OM content, flight altitudes did not significantly differ in prediction abilities. Satellite imagery was evaluated using data from Planet Labs as well as Google Earth. Regression models were developed to predict sand, clay, and soil organic matter content from these satellite …

Investigation Of Consumer Acceptability Of Beverages Through Automated Facial Expression Analysis And Overall Liking, Funan Jiang

Using Two Reinforcement Contingencies To Alter Teachers' Rates Of Praise, Ashleigh Eaves

Dissertations

The current study evaluated the effects of a positive and negative reinforcement contingency on teachers’ use of behavior specific praise (BSP) in the educational setting. An alternating treatments design was used across four participants in a rural, Southern elementary to determine if one or both conditions was successful in increasing the use of BSP. Data were collected on teachers’ use of BSP, general praise, general reprimands, and behavior specific reprimands (BSR). Additionally, student engagement in academically-associated and/or disruptive behaviors was measured throughout baseline, treatment, and follow-up phases. Results indicate both the positive and negative reinforcement contingency were successful in improving …

Investigation Of An Elevational Gradient Reveals Strong Differences Between Bacterial And Eukaryotic Communities Coinhabiting Nepenthes Phytotelmata, Kadeem J. Gilbert, Leonora S. Bittleston, Mark Arcebal K. Naive, Anthony E. Kiszewski, Perry Archival C. Buenavente, David J. Lohman, Naomi E. Pierce

Biology Faculty Publications and Presentations

Elevation is an important determinant of ecological community composition. It integrates several abiotic features and leads to strong, repeatable patterns of community structure, including changes in the abundance and richness of numerous taxa. However, the influence of elevational gradients on microbes is understudied relative to plants and animals. To compare the influence of elevation on multiple taxa simultaneously, we sampled phytotelm communities within a tropical pitcher plant (Nepenthes mindanaoensis) along a gradient from 400 to 1200 m a.s.l. We use a combination of metabarcoding and physical counts to assess diversity and richness of bacteria, micro-eukaryotes, and arthropods, and …

From The Dinner Pot To Smoking Pot; How A Better Understanding Of Cannabidiol In Crayfish Could Alleviate Anxiety And Modulate Hunger, Christopher Michael Timmer

Masters Theses

Anxiety affects approximately 1/3 of the US population and presents in many different forms, ranging from social to panic disorders. It also presents with high comorbidity for other mental disorders. One treatment is Selective Serotonin Reuptake Inhibitors (SSRIs) which allow for increased activation of serotonin (5-HT) receptors. SSRIs come with an extensive list of side effects, which can fail to maintain quality of life. Cannabidiol (CBD) is a cannabis derived compound which has been shown to decrease anxiety by activation of multiple subtype 5-HT amine receptors. CBD has few side effects, is not psychoactive, and exhibits anti-psychotic properties. The current …

Competitive Interactions: Spatial And Temporal Niche Partitioning Between Brook And Brown Trout In Southwest Michigan, Frederick J. Glassen

Masters Theses

Niche diet partitioning between Brook Trout and Brown Trout were studied in two southwestern Michigan, USA streams, one dominated by Brook Trout, the other with both Brook and Brown Trout. Brook Trout are endemic to eastern North America and have been introduced throughout the world for sport fishing. Brown Trout were first introduced to Michigan in 1883 using a genetic strain from Germany. Stomach contents were collected from a population of Brook Trout in the absence of Brown Trout in Frost Creek, while the other population was in potential competition with Brown Trout in Cedar Creek. Absent Brown Trout, Brook …

Carbon Sequestration In A Restored West Michigan Oak Savanna: Implications For Management Practices, Jeffrey A. Heise

Masters Theses

The savanna system is an ecosystem (i.e. a transitional ecosystem) that lies between forest and grassland ecosystems. They occur across the world in various forms, but in the North American Midwest they are specifically oak savannas: systems where the open overstory is dominated by various species of oak (Quercus spp.) and the understory consists of carbon-rich prairie grasses and forbs. This ecosystem is a highly degraded ecosystem and has lost almost 99% of its former range due to agriculture and fire suppression. Since savannas are fire-evolved systems, they are maintained by and require fire as a regular disturbance to …

Differentiating Literacy Instruction Through Guided Reading, Emily Clare Ringquist

Masters Projects

Research reiterates how instilling a strong reading foundation in young students is vital to their growth in the future. Today, students need more support and individualized education to meet the diverse needs students enter school with. Whole group reading instruction does not benefit students in comparison to differentiated instruction. In order to differentiate instruction to meet the needs of the students as well as provide scaffolds to enhance literacy, teachers must incorporate small group instruction such as guided reading groups.

Guided reading are groups of students around the same developmental level that showcase similar learning needs exploring books. Teachers work …
