The Impact Of Natural Disasters On Employee Turnover: The Shocks And After-Shocks Of Hurricane Katrina On It Professionals, James Davis

LSU Doctoral Dissertations

Hurricane Katrina was the most destructive natural disaster in American history and created the need for organizations along the Gulf Coast to employ disaster management and recovery plans. With the ubiquitous nature of computers and technology, IT professionals were critical organizational assets in executing those plans in order to insure the safety and recovery of valuable information. 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 …

Nevertheless, these operations are needed in various cryptographic systems. This thesis examines various scalable implementations of elliptic curve scalar …

Solving An Mri Spin Relaxometry Problem Using Parallel Java, Hardik Parikh

Theses

Magnetic resonance imaging (MRI) is an imaging technique used primarily in the medical profession to produce high quality images of the inside of the human body, without using x-rays. The process of obtaining the spin density spectrum from the time samples of the spin signal for each pixel of a magnetic resonance image is known as MRI spin relaxometry. The spin density spectrum is obtained by performing linear regularization on samples of magnetic resonance images obtained at different times. The spin density spectrum obtained from the body is used by radiologists to diagnose disease in its early stage. However, the …

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 …

Nonlinear H(Infinity) Missile Longitudinal Autopilot Design With Theta-D Method, Ming Xin, S. N. Balakrishnan

Mechanical and Aerospace Engineering Faculty Research & Creative Works

In this paper, a new nonlinear H 1 control technique, called μ¡D H 1 method, is employed to design a missile longitudinal autopilot. The μ ¡D H 1 design has the same structure as that of linear H 1 , except that the two Riccati equations that are part of the solution process are state dependent. The μ ¡D technique yields suboptimal solutions to nonlinear optimal control problems in the sense that it provides an approximate solution to the Hamilton-Jacobi-Bellman (HJB) equation. It is also shown that this method can be used to provide an approximate closed-form solution to 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 …

Mycobacteriosis-Associated Mortality In Wild Striped Bass (Morone Saxatilis) From Chesapeake Bay, Usa, D. T. Gauthier, R. J. Latour, D. M. Heisey, C. F. Bonzek, J. Gartland, E. J. Burge, W. K. Vogelbein

Biological Sciences Faculty Publications

The striped bass (Morone saxatilis) is an economically and ecologically important finfish species along the Atlantic seaboard of the United States. Recent stock assessments in Chesapeake Bay (USA) indicate that non-fishing mortality in striped bass has increased since 1999, concomitant with very high (>50%) prevalence of visceral and dermal disease caused by Mycobacterium spp. Current fishery assessment models do not differentiate between disease and other components of non-fishing mortality (e. g., senescence, predation); therefore, disease impact on the striped bass population has not been established. Specific measurement of mortality associated with mycobacteriosis in wild striped bass is …

Framing Strategies Of Lesbian, Gay, Bisexual, Transgender Advocacy Organizations: The Case Of Let California Ring's 'Garden Wedding' Commercial, Helena Mica

Electronic Theses and Dissertations

Framing is the process of presenting a complicated argument by relying on the ideas and concepts that a person already has regarding a basic subject. The idea of same-sex marriage has traditionally been presented by Lesbian, Gay, Bisexual, Transgender (LGBT) advocacy organizations using a frame of equal rights, with same-sex couples seeking equal treatment under the law. However, due to a lack of support for this argument, the organization Let California Ring introduced the 'Garden Wedding' commercial in the fall of 2007 that presented same-sex marriage in a new, emotional frame. The purpose of this thesis is to examine the …

Influence Of A Collaborative Norming Process On Teacher Perceptions Of Middle Level Team Structure And Development, Brian Miller

Electronic Theses and Dissertations

The teaming concept has served as a cornerstone of middle level philosophy and education since the middle school movement began in the 1960s. The literature on teaming is quite extensive and the interpretations of that research often differ among schools. For the purpose of this study, teaming is defined as a small group of teachers with different content responsibilities who work with the same group of students in a school-within-a-school structure. Described as a signature practice in the middle school movement, teaming provides an organizational framework that allows schools to design and deliver effective learning to every student (Crow and …

Show And Tell: Learning With Interactive Videoconferencing In Kindergarten, Debra Piecka

Electronic Theses and Dissertations

The research investigated how kindergartners make meaning using interactive videoconferencing. The study explored two research questions: 1) What types of meanings are being formed by the kindergartners during interactive videoconferences and, 2) What are the nature of young children's emerging inquiries and dialogue surrounding their use of interactive videoconferencing in their classroom? The study embodied a Vygotskian perspective as the theoretical framework in order to meet demands associated with the young participants' vulnerability, developmental appropriateness, and the students' interactive learning environment. Employing an ethnographic, participant observation methodology, the research design was informed by three criteria: 1) a pilot study, 2) …

The Effect Of Selective Cholinergic Lesion Of Medial Septum On Recognition Memory, Li Cai

Electronic Theses and Dissertations

The objective of this study was to clarify the role of septal-hippocampal cholinergic neurons in object and spatial recognition memory. Stereotaxic-surgical infusion of the selective cholinergic neurotoxin, 192IgG-saporin (SAP), into the medial septum (MS) of Sprague-Dawley rats was utilized to establish an animal model of cholinergic deficit of the septal-hippocampal tract, which had been expected as a pathologic model of memory impairment for Alzheimer's disease (AD). Three types of recognition memory were examined: retrograde object recognition, anterograde object recognition, and anterograde spatial recognition. These were examined with a modified version of a standard object recognition paradigm. For retrograde memory retention …
