Quantitative analysis was conducted to determine the housing situations of the families and the relationships of these factors with the family economic and cognitive well-being and employment circumstances of study participants. Discriminant analysis was used to develop a model to predict the employment circumstances (employed, not employed) of the participants. Housing costs usually take the first and …

The Dual Paths Of A Political Movement: Convergence And Divergence In Contemporary Conservative Public Address, Lyman Davis Hunt

LSU Doctoral Dissertations

This study examines the rhetorical choices made in public addresses by members of the contemporary conservative movement in the United States during the 1990s. The contemporary conservative movement in this instance is defined as a post World War II phenomenon. Specifically, it is argued that the popular notion of a unified conservative ascendence in America is but an illusion. Rather, two distinct tribes of conservatives, the economic and the traditional conservative, participate in a rhetorical homology that serves to hide significant ontological differences beneath the dialectical God terms freedom and order. Additionally, the charismatic nature of the term freedom authorizes …

Improved Bottomhole Pressure Control For Underbalanced Drilling Operations, Carlos Perez-Tellez

LSU Doctoral Dissertations

Maintaining underbalanced conditions from the beginning to the end of the drilling process is necessary to guarantee the success of jointed-pipe underbalanced drilling (UBD) operations by avoiding formation damage and potential hazardous drilling problems such as lost circulation and differential sticking. However, maintaining these conditions is an unmet challenge that continues motivating not only research but also technological developments. This research proposes an UBD flow control procedure, which represents an economical method for maintaining continuous underbalanced conditions and, therefore, to increase well productivity by preventing formation damage. It is applicable to wells that can flow without artificial lift and within …

Investigation Of Bond Slip Between Concrete And Steel Reinforcement Under Dynamic Loading Conditions, John Henry Weathersby

LSU Doctoral Dissertations

Structural failures during recent earthquakes and terrorist attacks have demonstrated shortcomings in the design procedures for reinforced concrete structures. Earlier research has demonstrated that a major limitation of the Finite Element (FE) modeling of the response of reinforced concrete is the accurate modeling of the interaction of the concrete with the steel reinforcement. Presently, there are insufficient data on the dynamic nonlinear interaction between the concrete material and the steel reinforcement to develop a numerical model of this interaction. The primary objective of this study was to experimentally investigate the dynamic interaction (bond slip) of reinforcement with concrete and gain …

Optimal Excess Noise Reduction In Thin Heterojunction Al0.6Ga0.4As-Gaas Avalanche Photodiodes, Oh-Hyun Kwon, Majeed M. Hayat, Shuling Wang, Joe C. Campbell, Archie L. Holmes, Yi Pan, Bahaa E.A. Saleh, Malvin Carl Teich

Electrical and Computer Engineering Faculty Research and Publications

It has been recently found that the initial-energy effect, which is associated with the finite initial energy of carriers entering the multiplication region of an avalanche photodiode (APD), can be tailored to reduce the excess noise well beyond the previously known limits for thin APDs. However, the control of the initial energy of injected carriers can be difficult in practice for an APD with a single multiplication layer. In this paper, the dead-space multiplication recurrence theory is used to show that the low noise characteristics associated with the initial-energy effect can be achieved by utilizing a two-layer multiplication region. As …

Hydrodynamic And Sediment Transport Modeling Of Deltaic Sediment Processes, Hassan Shahid Mashriqui

There appears to be a consensus among educators that teaching with new technologies requires new methods of evaluation. Although there is a body of research investigating the effects of computer-assisted instruction on student learning with largely favorable results, few studies have examined the efficacy of technology in integrated classrooms. This study was designed to determine if teachers at Advanced Technologies Academy improved their management, instruction, and student learning with the use of technology.

Using survey research methodology, the study sample, consisting of 25 teachers, provided information on their perceptions regarding technology integration and instructional effectiveness, student benefits, utilization of technological …

"Above The Noise And The Glory": Tiers Of Propaganda In Great War Literature, Margaret L. Clark

LSU Doctoral Dissertations

"Above the Noise and the Glory:" Tiers of Propaganda in Great War Literature illuminates the literary responses of Rupert Brooke, Mary Borden, Alice-Dunbar Nelson and Willa Cather to the manner in which the threat to one's cultural community, as well as personal and physical landscape, transforms a nation's, and even a world's, people from a state of complacency or purposelessness to one of jingoistic fervor. Prompted and inspired by personal, political and cultural forces, these writers mobilized early twentieth-century private citizens' spirits of nationalistic pride and solidarity. Individual chapters place within historical and literary contexts how war propaganda, particularly British …

College of Nursing Faculty Research and Publications

Universal screening for domestic violence is recommended in many health care settings. This qualitative study was undertaken to explore the thoughts and feelings of Mexican American women regarding being asked questions about domestic violence by a health care provider. We wanted to further explore what characteristics about a nurse, or other health care provider, would give a woman confianza, the trust necessary to discuss this issue. Seven women, who self identified as abused or formerly abused, were recruited from a pool of Spanish-speaking women receiving services from a rural domestic violence agency in the midwestern United States. The researchers …

Nanocomposites Based On Poly (Ε-Caprolactone) (Pcl)/Clay Hybrid: Polystyrene, High Impact Polystyrene, Abs, Polypropylene And Polyethylene, Xiaoxia Zheng, Charles A. Wilkie

Chemistry Faculty Research and Publications

Nanocomposites of polystyrene, high impact polystyrene, acrylonitrile–butadiene–styrene terploymer, polypropylene and polyethylene have been prepared using an organically-modified clay that contains polycaprolactone—PCL-modified clay. Depending upon the mode of preparation of the PCL-modified clay, all three types of nanocomposites, immiscible, intercalated and exfoliated, may be produced. The materials have been characterized by X-ray diffraction, transmission electron microscopy, cone calorimetry, thermogravimetric analysis, and the evaluation of mechanical properties.

In Situ Reactive Blending To Prepare Polystyrene-Clay And Polypropylene-Clay Nanocomposites, Dongyan Wang, Charles A. Wilkie

Chemistry Faculty Research and Publications

Nanocomposites of polystyrene and polypropylene with organically-modified clay may be prepared by melt blending in a Brabender mixer the clay and the polymer. The presence of maleic anhydride increases the likelihood of nanocomposite formation for polystyrene but is less important for polypropylene. The materials that result are immiscible materials, in that the clay is not uniformly distributed throughout the polymer matrix, but there is polymer inserted between the clay layers. The results from cone calorimetry suggest that nanocomposite formation has occurred, since there is a significant reduction in the peak heat release rate.

A Stibonium-Modified Clay And Its Polystyrene Nanocomposite, Dongyan Wang, Charles A. Wilkie

Chemistry Faculty Research and Publications

Triphenylhexadecylstibonium trifluoromethylsulfonate has been prepared and ion-exchanged with sodium montmorillonite to obtain a new organically-modified clay. The clay has higher thermal stability than an ammonium clay; only a portion of the alkyl chain is lost during degradation and all of the antimony is retained. This clay has been used to prepare a polystyrene nanocomposite in which the clay is not uniformly distributed throughout the polymer. Nonetheless the polymer does insert into the clay layers and the d-spacing of the clay expands from 2.0 to 3.0 nm. The enhanced thermal stability of this system may mean that it could be …

Molecular Recognition Of No/No+ Via Multicenter (Charge-Transfer) Binding To Bridged Diarene Donors. Effect Of Structure On The Optical Transitions And Complexation Thermodynamics, Sergiy V. Rosokha, Sergey V. Lindeman, Rajendra Rathore, Jay K. Kochi

Chemistry Faculty Research and Publications

Bridged diarenes form very strong [1:1] complexes with nitrosonium/nitric oxide in which the NO moiety is optimally sandwiched in the cleft between a pair of cofacial aromatic rings which act as a molecular “Venus flytrap”. The spectral features of these associates are generally similar to those for [1:1] and [2:1] nitrosonium complexes with mononuclear alkyl-substituted benzenes, and they are appropriately described within the LCAO molecular-orbital methodology and the Mulliken (charge-transfer) formulation of donor/acceptor electronic transitions. The thermodynamics study indicates that the efficient binding is determined by (i) the close matching of the donor/acceptor redox potentials and (ii) the ability of …

Design And Synthesis Of Constrained Dipeptide Units For Use As Β-Sheet Promoters, Umut Oguz

LSU Doctoral Dissertations

The study of factors promoting beta-sheet formation has recently gained interest due to the suspected involvement of beta-sheets in brain degenerative diseases such as Alzheimer's disease (AD), Creutzfeldt-Jacob disease (CJD) and bovine spongiform encephalopathy. Understanding beta-sheet formation and the factors that stabilize beta-sheet structure may serve as a basis for future drug design. The extended structure of a beta-sheet can be stabilized by constrained amino acid analogs that are pre-organized to adopt the extended conformation. In this dissertation using innovative synthetic organic chemistry methods, two dipeptide units are designed and synthesized that are constrained to form the extended conformation and …

Design And Synthesis Of Handles For Solid-Phase Peptide Synthesis And Convergent Peptide Synthesis, Jose Giraldes

LSU Doctoral Dissertations

The recent popularity of methods for solid-phase peptide synthesis that use the 9-fluorenylmethyloxycarbonyl (Fmoc) group for N^α-amino protection has created a need for compatible anchoring linkages and handles. In an effort to develop mild new methods for use in solid-phase peptide synthesis (SPPS), a new ferrocene containing linker or “handle”, the 1’1-ferrocenyl carboxaldehyde handle was designed, synthesized, characterized and tested. This linker is analogous to those commercially available and developed by Barany. The ferrocenyl amine linker(FAL) releases C-terminal peptide amides upon acidolysis. Since the FAL handle is acid labile it is compatible with Fmoc and N^α-dithiasuccinoyl …

Barriers To Participation In Educational Programs As Perceived By First-Time Enrolling Freshmen In Higher Education, Julie Cason Mcdonald

LSU Doctoral Dissertations

Institutions of higher education face exceptional challenges in today’s environment. College costs are increasing, funding is decreasing and/or limited, public confidence is diminishing, the work-place is changing, and a shrinking pool of traditional-age college students exists. This creates an environment where colleges and universities find themselves competing for students. So that these institutions of higher education may better understand how to recruit, advise, and retain students, one must consider the barriers first-time freshmen encounter in the pursuit of formal learning as they enter college. The purpose of this study, therefore, was to determine the perceived barriers to educational participation held …

The Effects Of An Evening Structured Problem-Solving Procedure In Undergraduate College Students With Insomnia, Colleen E. Carney

LSU Doctoral Dissertations

Worry is often reported as interfering with sleep onset and sleep maintenance, and pre-sleep cognitive arousal can persist after successful behavioral treatment of insomnia. The present investigation will examine the effects of a "constructive worry" procedure in an undergraduate population with impaired sleep. Thirty-three undergraduate students who reported three or more nights per week in the last month of sleep onset and/or sleep maintenance problems, either recorded worries and possible solutions (experimental CW group) or recorded worries and completed worry questionnaires (control Worry group) for five nights. As hypothesized, the CW group had decreased pre-sleep cognitive and overall arousal relative …

In Chapter Two, I summarize Boal's career as an interactive theatre practitioner. My review includes synopses …

The Novelty Of Improvisation: Towards A Genre Of Embodied Spontaneity, David Alfred Charles

LSU Doctoral Dissertations

Improvisation has often been viewed and valued in terms of its service and resemblance to scripted traditions of theatre. Such a stance seriously undermines the significance and impact of this global performance modality, and has resulted in improvisatory modes being largely ignored or downplayed in modern historical accounts of theatre. This dissertation examines improvisation on its own terms, seeking to understand its unique features, functions and potentials, while freeing it from the heavy shadow of its scripted counterpart. To this end, the theories of literary critic, Mikhail Bakhtin, provide important methodological guideposts and allow the silhouette of the improvisational impetus …
