Examination Of A Method For Increasing Adjustment To And Compliance With Nasal Continuous Positive Airway Pressure (Cpap) In Persons With Obstructive Sleep Apnea Syndrome., Jack Allen Johnson Jr Jan 2001

Examination Of A Method For Increasing Adjustment To And Compliance With Nasal Continuous Positive Airway Pressure (Cpap) In Persons With Obstructive Sleep Apnea Syndrome., Jack Allen Johnson Jr

LSU Historical Dissertations and Theses

Obstructive sleep apnea syndrome (OSAS) is a serious medical condition that occurs during sleep and consists of episodes of complete (respiratory pauses) or partial obstruction (hypoventilation) of the upper airway. Approximately 80% of persons diagnosed with OSAS are prescribed nasal Continuous Positive Airway Pressure (CPAP) treatment, which has proven to be the treatment of choice for OSAS. However, noncompliance with CPAP treatment in OSAS patients is a widely recognized problem, and many persons refuse CPAP as a treatment option or fail to use it reliably. Investigations of CPAP use in OSAS patients have generally found that nightly use averages less …

Parenting Practices As A Moderator Of Exposure To Community Violence., Nicole Francingues Lanclos Jan 2001

Parenting Practices As A Moderator Of Exposure To Community Violence., Nicole Francingues Lanclos

LSU Historical Dissertations and Theses

Numerous studies evidence that urban youth are exposed to epidemic proportions of community violence. Exposure to community violence has been associated with significant levels of distress including aggression, academic difficulties, anxiety, depression, and posttraumatic stress disorder. Although it is clear that children who experience chronic levels of violence exposure are at increased risk for poor developmental outcome, the consequences of exposure are not the same for all children. Parenting factors found to buffer the effects of community violence exposure include family size, parental presence in the home, family support, parenting resources, family cohesion, and strong parental monitoring. It is less …

Show Me The Money: An Analysis Of The Impact Of Voter Recognition On The Campaign Spending Effects Of House And Senate Candidates., Nicholas Chad Long Jan 2001

Show Me The Money: An Analysis Of The Impact Of Voter Recognition On The Campaign Spending Effects Of House And Senate Candidates., Nicholas Chad Long

LSU Historical Dissertations and Theses

The focus of this dissertation is campaign spending in congressional elections. I examine the benefits that candidates receive from campaign expenditures. I think that challengers receive greater benefits from spending than incumbents, but that the extent of these benefits depends on the type of challenger. High-quality challengers are those that have previous experience in an important elective office, while low-quality challengers lack this experience. Because of this experience, high-quality challengers enjoy a higher level of recognition among the electorate than low-quality challengers. I think that the benefits that challengers receive from expenditures are inversely related to the level of recognition …

Voluntary Accounting Policy Choices Of Lower -Level Firms In Multi -Firm Organizations., Allen Kenneth Hunt Jan 2001

Voluntary Accounting Policy Choices Of Lower -Level Firms In Multi -Firm Organizations., Allen Kenneth Hunt

LSU Historical Dissertations and Theses

This study investigates the determinants of accounting choices for subsidiary firms in multi-firm organizations. A "subsidiary" is defined as either a company that is controlled (i.e., more than 50 percent ownership) by another corporation (its "parent") or is a firm under the parent company's influence (i.e., between 20 and 50 percent ownership). Previous studies focus exclusively on the parent company; hence little is known about making accounting procedure choices for subsidiaries. As a separate legal entity, a subsidiary's accounting policies should be of interest to its creditors, regulators, and noncontrolling minority-interest shareholders. The accounting procedure choices investigated are depreciation and …

A World Of Deference: Paradoxes Of Victorian Paternalism In John Ruskin, Charles Dickens, And John Stuart Mill., Peter Mitchell O'Neill Jan 2001

A World Of Deference: Paradoxes Of Victorian Paternalism In John Ruskin, Charles Dickens, And John Stuart Mill., Peter Mitchell O'Neill

LSU Historical Dissertations and Theses

This study examines the residual paternalist ideology in three canonical Victorian texts: namely, John Ruskin's The Nature of Gothic, Charles Dickens's Hard Times, and John Stuart Mill's Autobiography. In exposing an epistemological tension between paternalist and liberal beliefs---especially a putative concern for the working class---that exists in these texts, this discussion concludes that not only are the cultural forces of benevolent authority insidious in Victorian culture, but that the paradoxes that emerge in these texts may reflect a public ambiguity toward the prevalent structures sustaining Victorian paternalism. The three texts examined inscribe hierarchical principles---while ironically exposing them---in generally similar ways: …

Effects Of Bilingualism On Cognitive Processing In Adults., Christy J. Witt Jan 2001

Effects Of Bilingualism On Cognitive Processing In Adults., Christy J. Witt

LSU Historical Dissertations and Theses

The primary objective of this dissertation was to empirically test the implications of the code-switching hypothesis (Peal & Lambert, 1962) for nonlinguistic cognitive abilities in bilingual adults. It was hypothesized that bilinguals, by virtue of their ability to switching between two linguistic systems, may enjoy cognitive advantages in the nonlinguistic domain for tasks that require abilities related to language switching. It was postulated that the underlying mechanisms of code switching are the bilingual's abilities to inhibit the processing of irrelevant information and activate previously suppressed information. To determine if a bilingual advantage exists for these abilities, bilingual and monolingual adults …

Appalachia On Stage: The *Southern Mountaineer In American Drama., Laura Grace Pattillo Jan 2001

Appalachia On Stage: The *Southern Mountaineer In American Drama., Laura Grace Pattillo

LSU Historical Dissertations and Theses

This study examines the portrayal of Southern Appalachian people and their culture in American drama, discussing works from time periods that range from the 1880s to the 1990s. The plays are grouped into categories that are reflective of mainstream America's perceptions of Appalachian culture: (1) the importance of family and gender roles, including the insider/outsider romance plot, (2) issues of violence and conflict between both internal and external forces within the region in the context of wars, feuds, and environmental and labor abuses, (3) the importance of folk practice and belief including tales of the supernatural, superstitious and astrological traditions, …

Meiofaunal Colonization Of Artificial Substrates., Nazan Atilla Jan 2001

Meiofaunal Colonization Of Artificial Substrates., Nazan Atilla

LSU Historical Dissertations and Theses

Meiofaunal colonization of artificial substrates was investigated in a shallow estuarine embayment. Meiofauna colonized various artificial substrates rapidly, at a rate of 1000 individuals collector-1 day -1 regardless of season, suggesting that high abundances of meiofauna commonly exist in the water column. These water-column meiofauna may be important in fish diets and may serve as a dispersing pool that aids recolonization after disturbance events. Colonization of artificial substrates by transient meiofauna of unknown origin(s) occurred through the water column. To determine the source of meiofauna colonizing artificial substrates, sediment and pier-piling meiofauna were sampled and compared to artificial-substrate colonists. Assemblages …

Activist Advertising: Case Studies Of United Colors Of Benetton's Aids -Related Company Promotion., Heidi Jolene Brough Jan 2001

Activist Advertising: Case Studies Of United Colors Of Benetton's Aids -Related Company Promotion., Heidi Jolene Brough

LSU Historical Dissertations and Theses

This study explores how advertising and company promotion may be used to address social issues. In particular, I examine how the clothing company United Colors of Benetton attempted to position itself within the AIDS crisis. Specifically, this study investigates through case studies how the Benetton Group used activist advertising and company promotion to bring about social change concerning AIDS-related issues. I also attempt to account for the controversy that the promotion elicited through establishing the anomalous status of the company's promotion within traditional advertising efforts. The study begins with information concerning the AIDS crisis and AIDS activism and then moves …

A Drifter Study Of Advection, Deformations, And Patch Variances With Application To Larval Transport And Dispersal In Barataria Bay, Louisiana., Terry L. Schaefer Jan 2001

A Drifter Study Of Advection, Deformations, And Patch Variances With Application To Larval Transport And Dispersal In Barataria Bay, Louisiana., Terry L. Schaefer

LSU Historical Dissertations and Theses

Field studies were conducted to characterize flow fields and their effect on larval transport and retention within Barataria Bay, Louisiana. Drifter tracking and passive larval sampling was conducted monthly during the spring and summer months from 1994 through 1996. Fifteen drifter tracking sessions were conducted over full tidal cycles (diurnal). Drifter positions were determined approximately every thirty minutes using a GPS receiver. A spline interpolation was used to estimate drifter positions at synchronous five-minute intervals. An analytical methodology of Okubo and coworkers was used to compute deformations; and changes in patch variances from the drifter positions. Mean tidal advection and …

Fabrication Of Nanometer-Sized Protein Patterns Using Atomic Force Microscopy And Selective Immobilization, Kapila Wadu-Mesthrige, Nabil A. Amro, Jayne C. Garno, Song Xu, Gang Yu Liu Jan 2001

Fabrication Of Nanometer-Sized Protein Patterns Using Atomic Force Microscopy And Selective Immobilization, Kapila Wadu-Mesthrige, Nabil A. Amro, Jayne C. Garno, Song Xu, Gang Yu Liu

Faculty Publications

A new methodology is introduced to produce nanometer-sized protein patterns. The approach includes two main steps, nanopatterning of self-assembled monolayers using atomic force microscopy (AFM)-based nanolithography and subsequent selective immobilization of proteins on the patterned monolayers. The resulting templates and protein patterns are characterized in situ using AFM. Compared with conventional protein fabrication methods, this approach is able to produce smaller patterns with higher spatial precision. In addition, fabrication and characterization are completed in near physiological conditions. The adsorption configuration and bioreactivity of the proteins within the nanopatterns are also studied in situ.

Dietary Effects Of Soy Isoflavones On Growth And Carcass Traits Of Commercial Broilers, R. L. Payne, T. D. Bidner, L. L. Southern, K. W. Mcmillin

Faculty Publications

Three experiments (EXP) were conducted to determine the effect of soy isoflavones (ISF) on growth and carcass traits of commercial broilers. The EXP were conducted simultaneously and a common control was used. In each EXP, treatments were replicated five times with five chicks each. Average initial and final BW were 102 and 2,890 g, 102 and 2,657 g, and 102 and 2,803 g for EXP 1,2, and 3, respectively, and the EXP were conducted from 9 to 52 d posthatching. In EXP 1, the effects of graded levels of supplemental ISF above those typically found in a corn-soybean meal (C-SBM) …

Faculty Publications

The complete genome sequences are reported here of two field isolates of bovine coronavirus (BCoV), which were isolated from respiratory and intestinal samples of the same animal experiencing fatal pneumonia during a bovine shipping fever epizootic. Both genomes contained 31028 nucleotides and included 13 open reading frames (ORFs) flanked by 5′- and 3′-untranslated regions (UTRs). ORF1a and ORF1b encode replicative polyproteins pp1a and pp1ab, respectively, that contain all of the putative functional domains documented previously for the closest relative, mouse hepatitis virus. The genomes of the BCoV isolates differed in 107 positions, scattered throughout the genome except the 5′-UTR. Differences …

Effect Of Phytase On Production Parameters And Nutrient Availability In Broilers And Laying Hens: A Review, L. F. Hatten, D. R. Ingram, S. T. Pittman Jan 2001

Effect Of Phytase On Production Parameters And Nutrient Availability In Broilers And Laying Hens: A Review, L. F. Hatten, D. R. Ingram, S. T. Pittman

Faculty Publications

An increase in poultry production in recent years has led to greater use of poultry manure as fertilizer, which has, in turn, increased the amount of phosphorus runoff from fields fertilized with poultry manure. Phosphorus excretion in poultry manure can lead to water pollution when the manure is used as fertilizer. The need to maintain sufficient dietary phosphorus levels while reducing phosphorus excretion in poultry manure has led to an increase in the application of phytase to poultry feed in recent years. The use of phytase reduces phosphorus excretion in poultry manure by allowing the birds to utilize more of …

Effects Of Initiation Age Of Skip-A-Day Feed Restriction On Skeletal Development In Broiler Breeder Males, D. R. Ingram, L. F. Hatten, B. N. Mcpherson Jan 2001

Effects Of Initiation Age Of Skip-A-Day Feed Restriction On Skeletal Development In Broiler Breeder Males, D. R. Ingram, L. F. Hatten, B. N. Mcpherson

Faculty Publications

This experiment was conducted over an 18-week period to determine the effects of initiating a skip-a-day (SAD) feed restriction program at 2, 4, and 6 weeks of age on male broiler breeders. For each of the SAD treatments, feed intake was manipulated so that the breeder's recommended target weight was reached by all groups at 18 weeks of age. Males were evaluated for shank and keel length and head width at 7 and 18 weeks of age. The results of this experiment show that starting a SAD feeding program at 2, 4, or 6 weeks of age will decrease shank …

A Phylogenetic Analysis Of Variation In Reproductive Mode Within An Australian Lizard (Saiphos Equalis, Scincidae), Sarah A. Smith, Christopher C. Austin, Richard Shine Jan 2001

A Phylogenetic Analysis Of Variation In Reproductive Mode Within An Australian Lizard (Saiphos Equalis, Scincidae), Sarah A. Smith, Christopher C. Austin, Richard Shine

Faculty Publications

Saiphos equalis, a semi-fossorial scincid lizard from south-eastern Australia, is one of only three reptile species world-wide that are known to display geographic variation in reproductive mode. Uniquely, Saiphos equalis includes populations with three reproductive modes: oviparous with long (15-day) incubation periods; oviparous with short (5-day) incubation periods; and viviparous (0-day incubation periods). No Saipho populations show 'normal' scincid oviparity (>30-day incubation period). We used mitochondrial nucleotide sequences (ND2 and cytochrome b) to reconstruct relationships among populations from throughout the species' distribution in New South Wales, Australia. Under the phylogenetic species concept, phylogenetic analyses are consistent with the oviparous …

Faculty Publications

We have analyzed 35 widely distributed, polymorphic Alu loci in 715 individuals from 31 world populations. The average frequency of Alu insertions (the derived state) is lowest in Africa (.42) but is higher and similar in India (.55), Europe (.56), and Asia (.57). A comparison with 30 restriction-site polymorphisms (RSPs) for which the ancestral state has been determined shows that the frequency of derived RSP alleles is also lower in Africa (.35) than it is in Asia (.45) and in Europe (.46). Neighbor-joining networks based on Alu insertions or RSPs are rooted in Africa and show African populations as separate …

Rickettsia Felis: Molecular Characterization Of A New Member Of The Spotted Fever Group, D. H. Bouyer, J. Stenos, P. Crocquet-Valdes, C. G. Moron, V. L. Popov, J. E. Zavala-Velazquez, L. D. Foil, D. R. Stothard, A. F. Azad, D. H. Walker

Faculty Publications

In this report, placement of Rickettsia felis in the spotted fever group (SFG) rather than the typhus group (TG) of Rickettsia is proposed. The organism, which was first observed in cat fleas (Ctenocephalides felis) by electron microscopy, has not yet been reported to have been cultivated reproducibly, thereby limiting the standard rickettsial typing by serological means. To overcome this challenge, several genes were selected as targets to be utilized for the classification of R. felis. DNA from cat fleas naturally infected with R. felis was amplified by PCR utilizing primer sets specific for the 190 kDa surface antigen (rOmpA) and …
