Temporal Cycles, Sarah Anne Shearer Jan 2013

Temporal Cycles, Sarah Anne Shearer

LSU Master's Theses

Temporal Cycles explores how systems and changes in the human body parallel those in nature. The investigation takes the form of a print installation, which captures the essence of bodily processes. The serial nature of printmaking and the organic world plays an important role as biomorphic forms and hourglass shapes are repeated in numerous renditions that breathe, pulse, expand, wither, ovulate, and transform. Labyrinths of pattern, texture, and color connect the symbolic forms as the installation tracks the evolution of processes in the body, and the forms reveal themselves through their pictorial associations.

Lowbrow Art : The Unlikely Defender Of Art History's Tradition, Joseph R. Givens Jan 2013

Lowbrow Art : The Unlikely Defender Of Art History's Tradition, Joseph R. Givens

LSU Master's Theses

This thesis has as twofold purpose. First, it will show that Lowbrow Art fits into the framework of art history and is worthy of art history’s attention. Second, it will argue for a revalidation of “traditional” art historical methods by proving that the methods are applicable to a marginalized contemporary art movement. Lowbrow Art is one of the most distinctive and vibrant art movements in the world, but there has yet to be a thorough examination of this style. Despite the undeniable worldwide success of the Lowbrow Art movement, it remains relatively obscure in academic discourse. Perhaps one reason why …

Surface Studies Of Organic Thin Films Using Scanning Probe Microscopy And Nanofabrication, Venetia Denae Lyles

LSU Doctoral Dissertations

Porphyrins and metalloporphyrins have unique chemical and electronic properties and thus provide useful model structures for nanoscale studies of the role of chemical structure for electronic properties. Porphyrins have been proposed as viable materials for molecular-based information-storage devices, gas sensors, photovoltaic cells, organic light-emitting diodes and molecular wires. The function and efficiency of porphyrins in devices is largely attributable to molecular architecture and how the molecules are self-organized. Modifications of the porphyrin macrocycle, peripheral groups or bound metal ions can generate a range of electrical, photoelectrical or magnetic properties. The conductive properties are greatly influenced at the molecular level by …

Super-Aptamer Bio-Imprinted Hydrogels : An Investigation Into The Optimization And Characterization Of Cross-Linked Polymeric Materials Displaying Macromolecular Amplified Responses, Nicholas Alexander Gariano

LSU Doctoral Dissertations

It is becoming more important to detect ultra-low concentrations of analytes for biomedical, environmental, and national security applications. Equally important is that new methods should be easy to use, inexpensive, portable, and if possible allow detection using the naked eye. Detection of low concentrations of analytes generally cannot be achieved directly, but requires signal amplification by catalysts, macromolecules, metal surfaces or supramolecular aggregates. The rapidly progressing field of macromolecular signal amplification has been advanced using conjugated polymers, chirality in polymers, solvating polymers and polymerization/depolymerization strategies. The use of molecularly imprinted polymers is ideal for creation of novel sensors to meet …

Enculturational Practices In The Teaching Of Proof In Mathematics, Indira Venkata Chillara Jan 2013

Enculturational Practices In The Teaching Of Proof In Mathematics, Indira Venkata Chillara

LSU Doctoral Dissertations

Mathematics education reform is informed by constructivist theories that forefront student learning of concepts, and by sociocultural theories whose focus is on students’ mastery of mathematical practices. As Cobb (1994) pointed out, these theorizations are inconsistent with one another, leading to conflict as some theorists seek to promote their approach as the correct one. Alternatively, Cobb, and many others in the social constructivism or the situated cognition camps, seek some sort of integration or balancing of these priorities in pedagogical theorizing. Kirshner (2002, 2004, 2008) argued that instead of either selecting one theory or balancing/coordinating the two theories, we should …

Family-Related Risk Factors And Their Associations With Behavior Problems Of Children In Foster Care, Jena Leigh Ourso Jan 2013

Family-Related Risk Factors And Their Associations With Behavior Problems Of Children In Foster Care, Jena Leigh Ourso

LSU Master's Theses

Children in foster care are at risk for problems associated with breakdowns in their ecological system. Possible explanations for this may be that children’s daily interactions in early childhood are primarily with their parents. The relationship between child and parent (the dyad) is a crucial part of the way children grow and develop. Past research focuses on the child’s behavior problems as separate and isolated instead of focusing on the behavior problems as a symptom of the dysfunction in the dyad. This study explored the role of two specific risk factors for children in foster care and how these may …

Advancing The Field Of Polypeptoids Through The Synthesis Of Novel Architectures And Thermoresponsive Polymers, Samuel Henry Lahasky

LSU Doctoral Dissertations

Peptidomimetic polymers are an emerging class of polymers that are structurally related to polypeptides. Due to their structural similarities, these polymers can be used to study some of the physical aspects of polypeptides (for example, protein folding). They are also increasingly being used in the fields of biology and drug-delivery. Some members of peptidomimetic polymers include polyacrylamides, polyoxazolines and polypeptoids. Polymer synthesis and characterization has been performed for both polyacrylamides and polyoxazolines, with research dating back to the 1950s and 1980s respectively. Research in the field of polypeptoids has not been as extensive; however, emerging synthetic strategies are allowing for …

Effects Of A Brief Mindfulness Intervention On Negative Affect And Urge To Drink Among College Student Drinkers, Christine Vinci Jan 2013

Effects Of A Brief Mindfulness Intervention On Negative Affect And Urge To Drink Among College Student Drinkers, Christine Vinci

LSU Doctoral Dissertations

Problematic college student drinking can predict the subsequent development of severe alcohol use patterns. Several theories have proposed that negative affect (NA) plays a large role in the maintenance of substance use behaviors – a phenomenon supported in laboratory-based and clinical studies. It has been demonstrated that mindfulness meditation can improve the regulation of NA, suggesting that mindfulness may be very beneficial in treating problematic substance use behavior. The present study utilized a brief mindfulness intervention, followed by a NA mood induction in a sample of college student problematic drinkers (N = 207). A three by two by three factorial …

Development Of A Framework For Scaling Surfactant Enhanced Co₂ Flooding From Laboratory Scale To Field Implementation, Gbolahan I. Afonja Jan 2013

Development Of A Framework For Scaling Surfactant Enhanced Co₂ Flooding From Laboratory Scale To Field Implementation, Gbolahan I. Afonja

LSU Doctoral Dissertations

The efficiency of the use of CO2 as a displacement fluid in oil recovery is hampered by the existence of an unfavorable mobility ratio that is caused by the large difference in viscosity between the injected fluid (CO2) and the reservoir fluids. This viscosity contrast results in early CO2 breakthrough, viscous fingering, gas channeling, and consequently, the inability of CO2 to effectively contact much of the reservoir and the oil it contains. Improvement of sweep efficiency and mobility control in CO2 injection require solutions to these problems. The use of surfactants and other chemical means for mobility control has been …
