Resilience and Adaptation in a World System Periphery

Gavin Davies
The Lake Atitlan Basin of highland Guatemala boasted fertile soils and was rich in natural resources, making it an attractive area for permanent settlement. However, the region lacked a number of important items, such as salt, cotton, and obsidian, all of which had to be obtained through trade. Good agricultural land was also scarce in certain parts of the lake and the steep hillslopes were easily eroded, making it necessary for communities to maintain access...

Curricular Optimization

William G. Thompson-Arjona
Considering the significant investment of higher education made by students and their families, graduating in a timely manner is of the utmost importance. Delay attributed to drop out or the retaking of a course adds cost and negatively affects a student’s academic progression. Considering this, it becomes paramount for institutions to focus on student success in relation to term scheduling. Often overlooked, complexity of a course schedule may be one of the most important factors...

Mortgage Loans and Financial Security Among Middle-Aged and Older Americans

Qun Zhang
Abstract: Mortgage loan debt is prevalent among middle-aged and older Americans. With higher average outstanding balances, many people are unlikely to pay off their mortgage debt by retirement. Meanwhile, as people age, health shocks are more likely to occur. Medical expenses may compete with mortgage payments and relate to financial insecurity in later years. In order to alleviate financial strain during times of financial hardship, senior homeowners may find reverse mortgage the solution they are...

Low-Silica and High-Calcium Stone in the Newman Limestone (Mississippian) on Pine Mountain, Harlan County, Southeastern Kentucky

Garland R. Dever, Jack R. Moody, Thomas L. Robl & Lance S. Barron
Abstract: The coal industry of Kentucky is an important market for limestone. Coal producers use limestone as rock dust for explosion abatement in underground coal mines and as a neutralizing agent in surface-mine reclamation and acid-drainage control. Crushed stone is also used for constructing and maintaining haulage roads. In the Eastern Kentucky Coal Field, the coal-bearing rocks of Pennsylvanian age generally do not contain limestones that are thick enough to quarry or mine economically. But...

Effectiveness of Prophylactic Lingual Strengthening Exercises for Patients with Head and Neck Cancer a Systematic Review

Cassidy Pickens
Radiation treatment for head and neck cancer has devastating effects on swallowing ability. Prophylactic swallowing exercises are often recommended. However, the evidence for these exercises is equivocal and information regarding critical components of an exercise program is lacking. The purpose of this systematic review was to examine the evidence regarding lingual strengthening exercises as a component of a prophylactic swallowing program.

Ecology, Monogamy, and the Evolution of Animal Families

Jacqueline Dillard
Family-living has been recognized as a necessary prerequisite for the evolution of advanced cooperative societies, yet the evolutionary and ecological processes that drive the coupling of different forms of cooperation in family-based societies are still poorly understood. In my dissertation, I investigate the correlated evolution of parental care, monogamy, and cooperative breeding in a variety of family-based taxa. I explore the mating and social behavior of family-living beetles with incipient cooperation to better understand the...

Thomas M. Parris, Stephen F. Greb & Brandon C. Nuttall
Abstract: Kentucky gets approximately 95 percent of its electricity from coal-fired power plants, which produce significant amounts of carbon dioxide (CO2). In 2005, Kentucky coal-fired plants vented 102.8 million short tons of CO2 into the atmosphere. The economic vitality of the state will be affected by its ability to develop and apply a portfolio of technologies that will mitigate input of CO2 into the atmosphere. One technology that has the potential to assist in this...

Alcohol-Induced Impairment of Simulated Driving Performance and Behavioral Impulsivity in DUI Offenders

Nicholas A. Van Dyke
Abstract: Licensed drivers arrested for driving under the influence (DUI) of alcohol have increased rates of vehicle crashes, moving violations, traffic tickets, and contribute to an estimated 120 million occurrences of impaired driving per year (Evans, 2004; Jewett et al., 2015). Survey research on DUI offenders indicates traits of impulsivity (e.g., sensation seeking). Together, these pieces of evidence suggest that DUI offenders display patterns of impulsive action and risk-taking while driving. However, to-date DUI offenders...

Investigation of Subsurface Tar-Sand Deposits in Western Kentucky

David A. Williams, Martin C. Noger & Patrick J. Gooding
Abstract: Tar sands (also referred to as asphaltic sandstones, heavy-oil deposits, or bitumen-impregnated sandstones) in western Kentucky have been recognized as a potential mineral resource for over l 00 years. Past commercial development has been restricted largely to use as paving material. However, because of the ever-expanding demands for energy, these deposits have become the subject of increasing interest as a potential petroleum resource. Previous studies have provided estimates of the potential resources of shallow...

Hydrogeology and Ground-Water Monitoring of Coal-Ash Disposal Sites in a Karst Terrane near Burnside, South-Central Kentucky

Shelley Minns Hutcheson, Lyle V. A. Sendlein, James S. Dinger, James C. Currens & Arsin M. Sahba
Abstract: The effects of two coal-ash disposal facilities on ground-water quality at the John Sherman Cooper Power Plant, located in a karst region of south-central Kentucky, were evaluated using dye traces in springs. Springs were used for monitoring rather than wells, because in a karst terrane wells are unlikely to intercept individual conduits. A closed-out ash pond located over a conduit-flow system discharges to three springs in the upper Salem and Warsaw Formations along Lake...

Mutations of FUS Cause Aggregation of RNA Binding Proteins, Disruptions in Protein Synthesis, and Dysregulation of Nonsense Mediated Decay

Marisa Kamelgarn
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by motor neuron death and subsequent muscle atrophy. Approximately 15% of ALS cases are inheritable, and mutations in the Fused in Sarcoma (FUS) gene contribute to approximately 5% of these cases, as well as about 2% of sporadic cases. FUS performs a diverse set of cellular functions, including being a major regulator of RNA metabolism. FUS undergoes liquid- liquid phase transition in vitro, allowing for...
