School Days, Hope Rovelto

Theses

My thesis exhibition, 'School Days,' is a collection of autobiographical sculptures. My thesis is inspired by the difficult memories of my childhood education. During school I felt condescension from my teachers and peers; I felt like I was actually wearing a dunce cap. This body of work represents the feeling of being ostracized from others in a classroom. I used the form of school chairs for my sculpture. The school chairs are the primary metaphor reflecting my early formal education. We, western industrial society, have an almost universal relationship with the school chair. As an artist, I use its form …

The Effects Of Writing About Positive Reminiscence On Happiness With Adolescents, Alison M. Senter

Theses

Much research has been done with adults in the field of positive psychology, reminiscence, and journal writing. Previous findings reveal that reminiscing about positive memories enhances one's happiness, well-being, life satisfaction, and self-continuity. The current study sought to expand this to adolescence. A group of 19 male and female ninth graders from a northeastern, suburban high school were assigned to a positive reminiscence or a daily hassles journal writing group. Analyses revealed significant effects on participants' positive affect; journal writing in general and specifically writing only about positive memories both significantly increased participants' ratings of perceived positive affect. However, no …

Removal Of Manganese From An Alkaline Mine Drainage Using A Bioreactor With Different Organic Carbon Sources, Jared D. Edwards

University of Kentucky Master's Theses

The treatment of Mn and SO₄^2- contaminated mine drainage via a sulfate reducing bioreactor is expected to result in near-permanent immobilization of significant amounts of Mn and a portion of the sulfates within the matrix. This study tested several different combinations of organic amendments and inorganic substrates in an attempt to optimize sulfate reducing conditions and Mn removal capacity. Five different organic carbon sources, including corn mash, wood mulch, biosolids, soybean oil, and sorghum syrup in combination with five different inorganic substrates, including creek sediment, marble and limestone chips, polished gravel, and sand were tested in batch experiments. …

Precision Agriculture: Realizing Increased Profit And Reduced Risk Through Cost Map And Lightbar Adoption, Benjamin Michael Kayrouz

University of Kentucky Master's Theses

This thesis examines the use of two specific types of precision agriculture technologies: cost maps and lightbar. Cost maps visually depict spatial differences in production costs. The visual depictions of these costs are represented using ArcGIS in an attempt to aide farmers in further decision making. Results will show that cost maps have great possibilities in their addition to the set of tools that farmers use in decision making. This thesis will expand the understanding of lightbar from a partial budget study to a whole farm model incorporating competition across different enterprises for labor and capital. The results from the …

The Missing Link: Marital Virtues And Their Relationship To Individual Functioning, Communication, And Relationship Adjustment, Amanda Veldorale-Brogan

University of Kentucky Master's Theses

Relationship adjustment research is being expanded beyond established connections with communication and individual functioning. In recent years, researchers have looked to positive psychology and virtues. That research shifts the focus from psychopathology and communication to more core values and ways of being. The present study seeks to expand this knowledge base using Blaine Fowers (2000) framework of marital virtues. His framework views what a person puts into an intimate relationship as an important predictor of relationship adjustment. The present study uses this framework in conjunction with previous research to examine the direct and indirect links amongst individual functioning, marital virtues, …

Irritability, Executive Functioning, And The Alcohol-Aggression Relation, Aaron John Godlaski

University of Kentucky Master's Theses

The purpose of this investigation was twofold. First, to test the hypothesis that irritability and executive functioning (EF), two previously established risk factors for alcohol-related aggression, would interact to conjointly confer multiplicative risk for intoxicated violence that is not observed when testing either variable alone. Second, to test the hypothesis that irritability would mediate the relation between EF and alcohol-related aggression. EF was measured using seven well-established neuropsychological tests. Irritability was measured using the Caprara Irritability Scale-CIS. Participants were 310 male and female social drinkers between the ages of 21 – 35 years old. After consuming an …

An Evaluation Of Earthquake Ground-Motion Site Effects At Two Sites Underlain By Deep Soils In Western Kentucky, Jonathan Larry Mcintyre

University of Kentucky Master's Theses

Six earthquake acceleration time histories were used to evaluate the groundmotion response of two sites, VSAP and VSAS, near the New Madrid Seismic Zone. These earthquakes ranged in magnitude from M_w 3.6 to M_w 5.2 and were located 46 to 173 km away from the recording instruments. These two sites are underlain by thick sequences (100 and 590 m) of unlithified soil that have been shown to greatly influence earthquake ground motions.

Near-surface soil dynamic properties were characterized at the two sites using seismic SH-wave refraction, P-S suspension logging, borehole electrical logs, and geotechnical logging methods. The soil …

The purpose of this study is to gain a deeper understanding of the impact natural disasters have on IT professionals and their subsequent turnover decisions. The theoretical guide for this study was the Unfolding Model of Turnover (Lee and Mitchell 1994) that identifies …

Performing Photographs: Memory, History, And Display, Melanie A. Kitchens

LSU Doctoral Dissertations

In my study, I place concepts and practices of photography and performance in dialogue to enable our understanding of how photographs perform and how performance contains or can contain elements we attribute to photographs. The connection between photography and performance that most intrigues me is how they make memories and when collected or restored in some socially shared way make histories too. My specific aim is to understand how photographs and performance might benefit from each other in how they make and transmit memories and histories. To activate the study, I select and focus on five specific events in which …

Enriching Or Depleting: An Investigation Of Communication And Behavior Within The Family Business, Joyceia Marie Banner

LSU Doctoral Dissertations

Despite the prevalence of family firms, researchers often ignore the significant impact of the family on the business. Thus, if organizational scholars do not account for the family as a variable in their research, they will not account for a significant number of the organizations they purport to understand. The fact that family businesses comprise such a large percentage of organizations proves that the family business context deserves more attention from both organizational and organizational communication scholars. With this in mind, the original intent of this dissertation was to explore the impact of family relationships on communication practices and behaviors …

The Viability Of A Thermoelectric Fuel Conditioning System For A Diesel Engine Utilizing Biodiesel, Timothy Schriefer

Theses

Certain internal combustion engines, which run on hydrocarbon fuels, experience difficulty upon engine start-up in extreme cold weather. As ambient temperature decreases below the fuel cloud point and beyond, paraffin form in the fuel and eventually clog the fuel filter causing the engine to fail to start. This problem becomes more pronounced when the engine in question is a Diesel and the fuel utilized is biodiesel. As an alternative fuel source, biodiesel has many advantages; however, its cold weather performance is worse than even conventional diesel fuel. As biodiesel becomes more integrated into the world’s energy usage scenario, one of …

Crash History After Installation Of Traffic Signals (Warranted Vs. Unwarranted), Kenneth R. Agent, Eric R. Green

Kentucky Transportation Center Research Report

The objective of this study was to determine the change in crash history at intersections after installation of a traffic signal. Signals installed based on the warrants from an engineering study resulted in a decrease in angle collisions with an increase in the less severe rear end collisions. At intersections where signal warrants were not met, there was a smaller decrease in angle collisions and a larger increase in rear end collisions. The removal of unwarranted traffic signals did not result in a crash problem. The analysis shows that the warrants given in the MUTCD should be followed when determining …

Transmute, Joseph Montroy

Theses

Man has an enduring subconscious connection with anthropological imagery and narrative. This association extends to the methods and practices that place importance on certain objects over others. In every culture throughout history the shared understanding of existence has been determined by images, symbols and archetypes. Intuitive logic and shared unconscious knowledge pervaded the daily lives of pre-modern man. Early people maintained a stronger connection with nature, spirituality and the subconscious. Archaic man acknowledged one stone among many as possessing spiritual properties. That stone could become a sacred receptacle that differentiated it from all others and saturated it with meaning and …

Reincarnating The Micro Universe, Jeong Ah Bae

Theses

My “Reincarnation Series” traces the meaning of life, rebirth and the cycle of transformation. It is an outcome of my quest to bridge the internal and external worlds of human experience, rich with polarities and full of complementary forces and opposite energies, properties, and attributes. This blending of contrasts in our world creates beauty. My work stems from my belief in Buddhism and portrays the full engagement in the world of a person’s unreserved presence, including mental, emotional, physical, and spiritual energies. My work reveals how each individual is in a fluid web, within and without consciousness, receptive to growth. …

Indians, Land, And Ideology : The Disruption Of Nationalism In The Works Of Lydia Maria Child And Henry David Thoreau, Lynn Marie Fedele

Theses, Dissertations and Culminating Projects

This thesis discusses presentations of American Indian culture and civilization in mid-nineteenth century American literature, especially as written by two northern Abolitionist writers, Henry David Thoreau and Lydia Maria Child. Tracing how these presentations are used to work both with and against developing American nationalism, most importantly in terms of the morality of U.S. expansionism, this paper explores the connections between Indians and land. As race is critical in nineteenth century nationalism, and land is necessary to industrial capitalism and U.S. expansionism, how these constructs are linked ideologically serves to either uphold or challenge the spread ot the U.S. westward …

Anaerobic And Performance Adaptations To A “Live High–Train Low” Approach Using Simulated Altitude Exposure, Ian Ratz

Master's Theses and Doctoral Dissertations

The purpose of this study was to determine if a seven-day live high–train low (LHTL) simulated altitude exposure could improve (a) anaerobic and/or aerobic capacity (VO_2peak) in trained cyclists (n = 10) and (b) VO_2peak and/or 400m swimming performance in collegiate swimmers (n=8).

In procedures approved by the EMU Human Subjects Review Board, cyclists performed seven cycle ergometer trials to measure maximal mean power output (MMPO_4min), maximal accumulated oxygen deficit (MAOD), and VO_2peak, whereas swimmers completed five incremental arm ergometer trials (VO_2peak) and 400m swimming performance trials before and after LHTL. …

Differential Geometry In Cartesian Closed Categories Of Smooth Spaces, Martin Laubinger

LSU Doctoral Dissertations

The main categories of study in this thesis are the categories of diffeological and Fr\"olicher spaces. They form concrete cartesian closed categories. In Chapter 1 we provide relevant background from category theory and differentiation theory in locally convex spaces. In Chapter 2 we define a class of categories whose objects are sets with a structure determined by functions into the set. Fr\"olicher's $M$-spaces, Chen's differentiable spaces and Souriau's diffeological spaces fall into this class of categories. We prove cartesian closedness of the two main categories, and show that they have all limits and colimits. We exhibit an adjunction between the …

Modeling The Fate Of Pharmaceuticals And Personal Care Products In Sewage Treatment Plants, Craig D. Adams

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Chemical fate models can be used to estimate the transformation reactions and the partitioning behavior of pharmaceuticals and personal care products (PPCPs) in sewage treatment plants (STPs). Modeling the fate of PPCPs in a STP requires parameters such as rate constants or partition coefficients that are often unique to a specific STP, and that may exhibit significant temporal variability. Chemical fate models provide both a valuable test of our understanding of the fundamental underlying mechanisms regarding the fate of PPCPs in STPs, as well as a means of providing both qualitative and quantitative estimates for PPCP removal. This paper is …

Efficient Uncertainty Quantification Applied To The Aeroelastic Analysis Of A Transonic Wing, Serhat Hosder, Robert W. Walters, Michael Balch

Mechanical and Aerospace Engineering Faculty Research & Creative Works

The application of a Point-Collocation Non-Intrusive Polynomial Chaos method to the uncertainty quantification of a stochastic transonic aeroelastic wing problem has been demonstrated. The variation in the transient response of the first aeroelastic mode of a three-dimensional wing in transonic flow due to the uncertainty in free-stream Mach number and angle of attack was studied. A curve-fitting procedure was used to obtain time-independent parameterization of the transient aeroelastic responses. Among the uncertain parameters that characterize the time-dependent transients, the damping factor was chosen for uncertainty quantification, since this parameter can be thought as an indicator for flutter. Along with the …

Swimming Dynamics And Propulsive Efficiency Of Squids Throughout Ontogeny, Ian K. Bartol, Paul S. Krueger, Joseph T. Thompson, William J. Stewart

Biological Sciences Faculty Publications

Synopsis Squids encounter vastly different flow regimes throughout ontogeny as they undergo critical morphological changes to their two locomotive systems: the fins and jet. Squid hatchlings (paralarvae) operate at low and intermediate Reynolds numbers (Re) and typically have rounded bodies, small fins, and relatively large funnel apertures whereas juveniles and adults operate at higher Re and generally have more streamlined bodies, larger fins, and relatively small funnel apertures. These morphological changes and varying flow conditions affect swimming performance in squids. To determine how swimming dynamics and propulsive efficiency change throughout ontogeny, digital particle image velocimetry (DPIV) and kinematic …
