Ivr Test & Survey: A Computer Program To Collect Data Via Computerized Telephonic Applications, Louis H. Janda, Michael Janda, Eric Tedford

Psychology Faculty Publications

Several studies have demonstrated the advantages of using interactive voice response (IVR) technology to collect self-report data from research participants and recipients of psychological/medical services. IVR allows participants to phone a computer and respond to recorded questions by pressing the appropriate touch-tone keys on their telephone. Because this technology offers substantial benefits in terms of cost and efficiency, it is surprising that it has not been more widely utilized by researchers and practitioners. Along with the automation of the administration and scoring of tests or surveys, IVR provides for questioning to be adapted to the participants' responses. One possible explanation …

The Time-Course Of Vascular Adaptations Following Localized Short Term Exercise Training, Jason David Allen

LSU Doctoral Dissertations

This is a series of 3 experiments in the area of vasoreactivity. The first study investigated the stability and reproducibility of brachial artery flow-mediated dilation (BAFMD). Twenty-six healthy volunteers underwent 3 scans on 2 days, performed by 2 ultrasonographers, and analyzed by 2 readers. All subjects were tested between 7 and 11am after refraining from food and exercise. Average baseline diameter was 3.48±0.53mm, which increased to 3.71±0.57mm (6.58±4.15%) at peak dilation. ICCC's for days, testers and readers were 0.9188, 0.9394, and 0.8982 respectively. To detect a difference in vasoreactivity of 60% (two-tailed), e.g. 5% vasodilation versus 8% vasodilation, at 90% …

Heavy Metal Distribution For Aqueous And Solid Phases In Urban Runoff, Snowmelt And Soils, Donald W. Glenn Iii

LSU Doctoral Dissertations

At the start of the third millennium, over 50% of the world’s population lives in urban areas. Anthropogenic activities associated with urban development such as traffic generate significant particulate and heavy metal mass loadings. Ten urban highway sites located throughout the metropolitan area of Cincinnati, Ohio were studied. Storm water, snow and transportation land use soil/residual complexes (RSCs) were collected at each site. For the storm water, results are presented for a series of eight rainfall runoff events over a two-year period and included analyses between dissolved and particulate-bound fractions of heavy metals (Pb, Cu, Cd and Zn), and water …

Breakdown Voltage In Thin Iii-V Avalanche Photodiodes, Mohammad A. Saleh

Electrical and Computer Engineering Faculty Research and Publications

1. The dead-space multiplication theory of Hayat et al. [Journal of Lightwave Technology 10, 1415 (1992)], in conjunction with the multiplication-width-independent ionization-coefficient model developed by Saleh et al. [IEEE Trans. Electron Devices 47, 625 (2000)], are shown to accurately predict breakdown voltages for thin avalanche photodiodes of GaAs, InP, In_0:52Al_0:48As, and Al_0:2Ga_0:8As, over a broad range of device widths. The breakdown voltage is determined from the analytical expression for the impulse-response-function decay rate.

Designing Molecular Recognition In The Context Of Hydrogen Bonding And Molecular Dynamics, Peter G. Willis

University of Kentucky Doctoral Dissertations

The effect of hydrogen bonding on the conformation of organic moleculesunifies two projects in this thesis. In one project, the stability of the intramolecularhydrogen bond in derivatives of 2-guanidinobenzimidazole was studied bydynamic 1H NMR spectrometry. The impact that this intramolecular hydrogenbond had on the bond order of the neutral guanidino group and on the dynamicconformation of these aromatic structures was related to the concept of hydrogenbond-assisted resonance. In another project, an oligomer possessing repetitiveconformation and capable of much inter- and intramolecular hydrogen bondingwas designed and synthesized. The sensitivity of this oligomer to changes inanion concentration, as well as its own …

Characterization Of Epitheliogenesis Imperfecta In Equus Caballus, Louis D. Lieto

University of Kentucky Doctoral Dissertations

Epitheliogenesis Imperfecta (EI) is a mechanobullous disease that occurs in newborn American Saddlebred and Belgian Draft foals. Necropsy evaluations of two American Saddlebred foals revealed broad skin lesions, dental abnormalities and oral mucosa lesions. Construction of a partial pedigree showing occurrences of EI in American Saddlebred horses was consistent with a recessive pattern of inheritance. An allelic frequency of 0.04 was estimated for the EI gene. The pathological signs of EI were similar to a disease in humans known as Herlitz Junctional Epidermolysis Bullosa (HJEB). HJEB is caused by a defect in one of the three subunits of the laminin …

Resistance Exercise Training Attenuates Wasting Of The Edl Muscle In Mice Bearing The Colon-26 Adenocarcinoma, Sadeeka Al-Majid, Donna O. Mccarthy

College of Nursing Faculty Research and Publications

Progressive wasting of skeletal muscle is a significant side effect of malignancy. Perturbations in protein metabolism contribute to this state of wasting. Resistance exercise increases protein synthesis and mass of healthy muscles and counteracts muscle wasting associated with several catabolic conditions. It is not known whether resistance exercise training can counteract cancer-induced muscle wasting. This study examined the effect of resistance exercise training on muscle mass and protein content in 9 mice bearing the colon-26 adenocarcinoma. The dorsiflexor (extensor digitorum longus [EDL] and tibialis anterior) and plantar flexor (soleus, plantaris, and gastrocnemius) muscles of 1 leg of the tumor-bearing and …

Cancer-Induced Fatigue And Skeletal Muscle Wasting: The Role Of Exercise, Sadeeka Al-Majid, Donna O. Mccarthy

College of Nursing Faculty Research and Publications

Fatigue is the most frequently reported symptom by cancer patients. Many of these patients perceive fatigue as the most distressing symptom associated with their illness because it imposes limitations on their physical activity level. Skeletal muscle wasting, which occurs as part of cancer cachexia, is one of the mechanisms that contribute to fatigue. Cancer induced skeletal muscle wasting may occur despite normal food intake and is not prevented by nutritional supplementation. Evidence suggests that endurance exercise ameliorates cancer-related fatigue. There is no compelling evidence to support that exercise induced reduction in fatigue is related to preservation of muscle mass. Resistance …

Synthesis Of Cyclopropanes Via Organoiron Methodology: Preparation Of 2-(2′-Carboxy-3′-Ethylcyclopropyl)Glycine, Kamil Godula, William A. Donaldson

Chemistry Faculty Research and Publications

A route to 1,2,3-trisubstituted cyclopropanes has been developed. The relative stereochemistry at the three cyclopropane centers is established by nucleophilic attack on the pentadienyl ligand on the face opposite to iron and subsequent oxidatively induced reductive elimination with retention of configuration. This methodology was applied to the synthesis of 2-(2′-carboxy-3′-ethylcyclopropyl)glycines. The diastereomeric glycine dimethyl esters are separable as their diphenylmethylene imines.

The conformationally restricted glutamate analogs (2S,1′S,2′S,3′R)- and (2R,1′S,2′S,3′R)-ECCG's 5a and5b were prepared in five steps (17 and 15% yield, respectively) from (pentadienyl)Fe(CO) …

Photooxidation Of Polymeric-Inorganic Nanocomposites: Chemical, Thermal Stability And Fire Retardancy Investigations, Adams Tidjani, Charles A. Wilkie

Chemistry Faculty Research and Publications

Nanocomposites of polypropylene-graft-maleic anhydride/clay and polypropylene/clay were prepared by melt blending using two different approaches. X-Ray diffraction results showed an intercalated structure. Samples of nanocomposites were exposed to UV light under atmospheric oxygen and their photo-oxidative stability was studied using FTIR and UV spectroscopy. The consequences of this photo-oxidation on the thermal stability and fire retardant performance of the nanocomposites were also addressed from thermogravimetry analysis and Cone calorimetry.

Xps Characterization Of Friedel-Crafts Cross-Linked Polystyrene, Jiangqi Wang, Jianxin Du, Hongyang Yao, Charles A. Wilkie

Chemistry Faculty Research and Publications

The combination of a difunctional alkylating agent, either hydroxymethylbenzyl chloride or α,α′-dichloroxylene with polystyrene or high-impact polystyrene together with a Friedel-Crafts catalyst, 2-ethylhexyldiphenylphosphate, and an amine to react with hydrogen chloride has been studied by X-ray photoelectron spectroscopy. The results confirm what had been suggested from previous investigations using thermogravimetric analysis; cross-linking of the polymer occurs as the temperature is raised and the alcohol-containing alkylating agent gives a greater amount of cross-linking than does the dichloro compound.

Lithospheric Flexure Of The Devils Lake Basin, North Dakota, Erica M. Peterson

Theses and Dissertations

Devils Lake is the largest lake in a chain of approximately 20 interconnected lakes in east central North Dakota. The Devils Lake drainage basin of approximately 8,600 km2, lies in a bowl sculpted by glaciation; thus it is closed and receives and loses water only through precipitation and evapotranspiration. Since 1940, the lake level has risen 14.4 m due to increased precipitation. Geological data show that in the past 10,000 years the lake has alternately dried up and filled due to climate fluctuations (Murphy et al., 1997). During this time it has reached its spill elevation of 444. 7 m …

The Role Of Experience And Active Learning In Web-Based Training For Applying Knowledge, Deborah L. Dunaway

LSU Doctoral Dissertations

The purpose of this study was to test a new method for presenting information on the internet in a format that enhances adaptive learning and transfer to real-world applications. This web-based training method, called Cognitive Toolboxes (Mathews, 2001) involves analyzing course content into goal-based categories (toolboxes) linked to sets of knowledge facets (tools) and applications (cases). Three experiments examined the effects of internet access to different aspects of toolbox content (tools, toolbox names and cases) on subsequent application of the material to real-world problems. Results show that access to the organizational aspects of the method (tools organized into toolboxes) facilitated …

"Encourager Le Commerce Et Répandre Les LumiʹEre" : The Press, The Provinces And The Origins Of The Revolution In France: 1750-1789, Stephen Auerbach

LSU Doctoral Dissertations

This dissertation examines the political, intellectual, and cultural significance of France's provincial newspaper press, called affiches, published between 1750-1789. Combining the histories of the press, provincial life, and the public sphere, this dissertation explores the ways in which the affiches became an indispensable part of local economic, cultural, and intellectual life while at the same time articulated a world view that was antithetical to the tenets of monarchical absolutism. The first part of the dissertation focuses on the origins, form and contents of the provincial press. Faced with the twin obstacles of laws governing censorship and privilege, provincial newspapers eschewed …

An Xps Investigation Of Thermal Degradation And Charring Of Cross-Linked Polyisoprene And Polychloroprene, Jianwei Hao, Charles A. Wilkie, Jiangqi Wang

Chemistry Faculty Research and Publications

Our interest in butadiene-containing polymers had led to an investigation of the thermal degradation of polyisoprene, PIP, and polychloroprene, PCP. The connection between cross-linking and thermal stability through an examination of PIP and PCP has been reported. Like the course of thermogravimetric analysis (TGA) the cross-linking and charring of polymers subjected to heat can also be experimentally observed as function of temperatures by the pseudo-in-situ XPS (X-ray Photoelectron Spectroscopy). Data acquisition of C1s spectra as function of temperature permits us to explore: (1) the extent of cross-linking and/or carbon accumulation of systems of PCP and PIP with/without initiators, BPO and …

The Thermal Stability Of Cross-Linked Polymers: Methyl Methacrylate With Divinylbenzene And Styrene With Dimethacrylates, Fawn Marie Uhl, Galina F. Levchik, Sergei V. Levchik, Caroline Dick, John J. Liggat, C.E. Snape, Charles A. Wilkie

Chemistry Faculty Research and Publications

Cross-linking of polymers is frequently presumed to enhance the thermal stability of polymer systems. Methyl methacrylate has been reacted with divinylbenzene and styrene with various dimethacrylates. These systems have been characterized by gel content, swelling ratio, infrared spectroscopy, thermal analysis, TGA/FT-IR, and solid state NMR. Both systems show enhanced thermal stability and char formation. This is most pronounced in the cases of methyl methacrylate with divinylbenzene and styrene with bisphenol A dimethacrylate.

Fire Properties Of Polystyrene-Clay Nanocomposites, Jin Zhu, Alexander B. Morgan, Frank K. Lamelas, Charles A. Wilkie

Chemistry Faculty Research and Publications

Polystyrene−clay nanocomposites have been prepared using a bulk polymerization technique. Three new “onium” salts have been used to prepare the nanocomposites, two are functionalized ammonium salts while the third is a phosphonium salt. By TGA/FTIR, both ammonium and phosphonium treatments have been shown to degrade by a Hofmann elimination mechanism at elevated temperatures. TGA/FTIR showed that the phosphonium treatment is the most thermally stable treatment when compared to the two ammonium salts. The nanocomposites were characterized by X-ray diffraction, transmission electron microscopy, strength and elongation at break, as a measure of the mechanical properties, thermogravimetric analysis, and cone calorimetry. The …

Thermal Degradation Of Pvc In The Presence Of Polystyrene, Qiang Yao, Charles A. Wilkie

Chemistry Faculty Research and Publications

The thermal degradation of poly(vinyl chloride) (PVC) and blends of PVC with polystyrene has been studied using thermogravimetric analysis coupled to Fourier transform infrared spectroscopy. The degradation of PVC commences at weak links by an ionic pathway, but there is evidence to suggest the presence of a radical pathway at high temperatures. While there is some chemical interaction between PVC and polystyrene, the principal mode of stabilization is a physical process.

Studies On The Mechanism By Which The Formation Of Nanocomposites Enhance Thermal Stability, Jin Zhu, Fawn Marie Uhl, Alexander B. Morgan, Charles A. Wilkie

Chemistry Faculty Research and Publications

Polystyrene−clay and polystyrene−graphite nanocomposites have been prepared and used to explore the process by which the presence of clay or graphite in a nanocomposite enhances the thermal stability of polymers. This study has been designed to determine if the presence of paramagnetic iron in the matrix can result in radical trapping and thus enhance thermal stability. Nanocomposites were prepared by bulk polymerization using both iron-containing and iron-depleted clays and graphites, and they were characterized by X-ray diffraction, transmission electron microscopy, thermogravimetric analysis, and cone calorimetry. The presence of structural iron, rather than that present as an impurity, significantly increases the …
