The Blind Scientist: A Critique Of Neo-Darwinism's A Priori Assumptions, Alexander James Bonitto

Masters Theses

This paper investigates neo-Darwinian fallacies specifically regarding a priori presumptions, leading to weak scientific methodology and praxis. It was found that five concepts must be true for neo-Darwinism to be true. These are gradualism, the tree of life hypothesis, the evidence of micro-evolutionary change accounting for macro-evolutionary change, time and chance, and methodological naturalism. Prima facie, these concepts have tremendous explanatory power. However, with an attempt to carefully examine these concepts, all five seem to be assumed a priori in order to dictate the outcome of neo-Darwinism rather than letting the evidence speak for itself. Coincidentally, it appears that the …

The Impacts Of Road Salt On Water Quality And Phosphorus Dynamics In An Urban Lake, Ellen Foley

Masters Theses

Road salt runoff from de-icing applications has notably increased chloride concentrations in lakes throughout north temperate regions of the planet, with negative impacts on freshwater ecosystems. For the past 20 months, I have monitored the water quality of a chloride-impaired lake and associated tributary in Grand Rapids, Michigan. Chloride levels in the deepest part of the lake have reached up to 331 mg/L, above EPA chronic toxicity thresholds. The salt-induced density gradient has prevented the lake from completely mixing during my study period and created persistent hypoxia in the hypolimnion. Total phosphorus (TP) concentrations in the hypolimnion can exceed 7500 …

On Hydrophobic Deep Eutectic Solvents: Thermo-Physical Properties And Applications In Gas Solubility, Shan Khai Liew

Masters Theses

Carbon dioxide (CO2) has been widely recognized as one of the greenhouse gases (GHGs) in the atmosphere. GHGs cause global warming, which will bring a lot of problems and irreversible changes. To curb CO2 emissions, much effort has been done. There are many technologies available for CO2 capture, such as amine scrubbing, pressure or temperature swing adsorption, membrane separation, and many solvents and absorbents that have been proposed for CO2 capture (e.g., zeolite, silica materials, graphene, activated carbon, etc.) at every stage (pre-combustion, post-combustion, oxy-combustion). However, these materials have their own drawbacks. Hydrophobic deep eutectic solvents (HDES) is a green …

Assessment Of Industrial Policies In Ghana: A Case Study On The Current Policy Of One District One Factory Policy (1d1f), Ama Nyamekye Obenewa Otoo

Masters Theses

Industrialization has been the weakest link in Ghana’s economic development efforts. Import-substitution industrialization policy of the 1960s-1980s and the outward liberalized industrialization policy of 1990-2020 (Vision 2020), have failed to achieve the goals of industrialization. This is due to several reasons including the selfish interests of these political leaders and lack of technological advancement. In 2017, the elected New Patriotic Party (NPP), announced a new industrialization policy known as “one district, one factory" (1D1F), which was a political campaign promise to realign industrial strategies. The goal of this policy is to ensure that industries are spread equitably among the country's …

The Eye Of The King: Screenplay Adaptation As A Craft Tool, Nora Annette Graves

Masters Theses

Adaptation studies typically focus on a screenplay’s fidelity to its original text within the constraints imposed by the new genre. This thesis approaches adaptation as a craft tool: a rich source of fresh authorial insight into characters, settings, and plotlines. Experimentation, not fidelity, is the goal of the self-adapter; adaptations are valued and deemed successful based on the new levels of complexity they uncover or add to an ongoing story. The author’s screenplay adaptation of her original novel, The Eye of the King, served as a case study for testing the value of adaptation as a writer’s craft tool. Re-telling …

Turning Small Steps Into Giant Leaps: Nasa’S Genesis And Its Culmination In The Apollo Program, Hunter L. Maples

Masters Theses

On July 16, 1969, NASA astronaut Neil Armstrong dropped himself onto the dusty surface of the Moon, momentarily followed by his lunar module pilot, Buzz Aldrin. It is simple to recognize the clear historical significance of the Apollo moon landings. It can also be easy, however, to overlook the work of thousands of individuals and decades of development that culminated in a lunar voyage. Because the moon landings were unprecedented, the hardware required had to be developed from scratch and mission protocol had to be written. Additionally, the United States was competing against its Cold War adversary, the Soviet Union, …

More Than A Bulleted List: Rethinking The Traditional Resume As A Way To Present The Unique Personality Of An Applicant, Andrew Alleman White

Masters Theses

Every business has its own unique culture, and the traditional resume fails to denote the personality and individualism of the applicant; this leads to wasted time interviewing the wrong applicants and missed opportunities to employ culturally beneficial employees. A culturally beneficial employee is one that fits the company culture and improves the performance of the entire team with both their skills and personality. The most advanced technologies available, are still using the traditional resume as a baseline for the sourcing, sorting, and evaluation of a potential hire. Even with the implementation of artificial intelligence to sort through the predetermined meta …

The Enemy Of My Enemy Is My Friend: George Washington And France, Brent Kyle Meyers

Masters Theses

This thesis looks at how George Washington was able to overcome his personal animosity towards France and ally himself with them during the American Revolution. This animosity originates with Washington’s early interactions with the French during the French and Indian War. It examines how the events during Washington first miliary mission and journey to Fort Le Boeuf, his first military conflict and surrender at Jumonville Glenn, and his service under General Braddock all helped develop that animosity. However, the overcoming of these early negative feelings for Washington was the culmination of three key factors. The first major guiding force was …

Explanatory Ultimacy, Epistemic Access, And Evil: A Community Theodicy, Jonathan Michael Huls

Masters Theses

This is a work about meaning and value. How do human persons find meaning? Why do human persons have value—or do we? A stubborn problem of meaning is evidenced by the perennially treated theistic problem of evil. How is an all-powerful, all-knowing, and morally perfect God compatible with a world filled with violence and hate? If God is powerfully perfect, why is His world not perfect too? This project endeavors to notice that an answer to this problem depends on properly grounding human access to meaning—especially the meaning of the words God, and evil. It is argued herein that there …

As the Inertial Measurement System (IMS) being a potential alternative to the Optoelectronic Measurement System (OMS) in terms of capturing comprehensive and objective musculoskeletal data, they need to be verified concurrently with the OMS before we start using the IMS in clinical motion analysis. To achieve this, a concurrent validity experiment of the Xsens system (IMS) in comparison to the Vicon system (OMS) was conducted for both upper and lower extremity movements during walk, squat, and lateral lunge (left and right) to quantify the degree of similarity of kinematic data between the two systems by direct comparison, root mean square …

Effects Of Prescribed Fire On Planted Oak Growth And Survival In Restored Savannas, Allison Earl

Masters Theses

Most oak savannas in the Midwestern United States have been lost to agriculture and habitat degradation. Because of their rarity and ability to support high plant and animal diversity, savannas are often a target for restoration. Oak savanna restoration frequently relies on direct planting of oak seedlings to establish the necessary tree canopy. Returning fire to the system is critical to the herbaceous component of the savanna, but managers risk damaging or killing trees if burning is introduced too soon. I studied growth and physiological responses of three oak species (Quercus alba, Q. macrocarpa, and Q. velutina …

Evaluation Of Mesenchymal Stem Cells In Autoimmune Disease: A Systematic Review And Meta-Analysis, Hailey Nicole Swain

Masters Theses

"Mesenchymal stem cells, also known as multipotential stem/progenitor cells and mesenchymal stem/progenitor cells, are denoted by the acronym MSCs. MSCs can differentiate into multiple lineages from different germ layers in vitro, and in limited situations, in vivo. MSCs have broad anti-inflammatory and immune-modulatory properties, which is the greatest focus of MSCs in clinical testing. Despite their promise and use in over 950 clinical trials, pivotal questions remain unanswered. Recent clinical trials have demonstrated that when MSCs are harvested from autoimmune patients, they show a reduction in their therapeutic efficacy in comparison to MSCs from a healthy person.

Optimizing The Placement Of Multiple Uav--Lidar Units Under Road Priority And Resolution Requirements, Zachary Michael Osterwisch

Masters Theses

"Real-time road traffic information is crucial for intelligent transportation systems (ITS) applications, like traffic navigation or emergency response management, but acquiring such data is tremendously challenging in practice because of the high costs and inefficient placement of sensors. Some modern ITS applications contribute to this problem by equipping vehicles with multiple light detection and ranging (LiDAR) sensors, which are expensive and gather data inefficiently; one solution that avoids vehicle-mounted LiDAR acquisition has been to install elevated LiDAR instruments along roadways, but this approach remains unrefined. The eventual development of sixth-generation (6G) wireless communication will enable new, creative solutions to solve …

Rapid-Throughput Analysis Of 1,4-Dioxane In Plants By Centrifugal Sampling And Phytoforensic Analysis For Site Delineation And Assessing Enhanced Rhizodegradation, Anthony Eberechukwu Oha

Masters Theses

"Owing to its broad use and environmental persistence, 1,4-dioxane (dioxane) poses a notable threat to public health and is recalcitrant to traditional remedial systems. Dioxane moves readily in an aqueous environment and is an emerging contaminant in drinking water, surface water, groundwater, and wastewater. The extent of dioxane in the biosphere is also difficult to delineate, particularly in the subsurface. Phytoremediation has demonstrated the potential for dioxane groundwater remediation.
