Dyslexic College Students: Quest For Literacy., Frances Grace Crochet Jan 1998

Dyslexic College Students: Quest For Literacy., Frances Grace Crochet

LSU Historical Dissertations and Theses

The initial purpose of this study focused on an Orton-Gillingham phonics remediation program and the effect the program had on college students. The emphasis of the study changed due to the fact that the Orton-Gillingham phonics program did not impact the college students' learning, which was mainly due to the students having previously received some form of phonics instruction. The students had learned to compensate for their poor spelling ability through invented spelling, and the use of the computer and the spell checker. The other accommodations that decreased their need for knowledge of a spelling program were the use of …

Concurrent Vs. Terminal Augmented Feedback In The Learning Of A Discrete Bimanual Coordination Task., Cynthia Marie Hadden Jan 1998

Concurrent Vs. Terminal Augmented Feedback In The Learning Of A Discrete Bimanual Coordination Task., Cynthia Marie Hadden

LSU Historical Dissertations and Theses

Two experiments compared the effects of concurrent and terminal augmented feedback in learning a bimanual coordination task. In the first experiment, twenty-four participants practiced a discrete bimanual task that required a 90$\sp\circ$ phase offset of the upper limbs under one of two feedback conditions: concurrent or terminal. Participants in the concurrent feedback group received feedback as they performed the task during acquisition. Participants in the terminal feedback group received feedback after they completed each acquisition trial. Results indicated that concurrent group was able to more accurately produce the target figure during acquisition than the terminal group. Unlike earlier studies which …

Serological And Molecular Biological Studies Of Marine Predator-Prey Systems., Marilyn J. Hoyt Jan 1998

Serological And Molecular Biological Studies Of Marine Predator-Prey Systems., Marilyn J. Hoyt

LSU Historical Dissertations and Theses

Two aspects of species identification were addressed; a molecular approach to identify anchovy larval and serological methods for prey detection in predator gut washes. Analysis of the pattern of restriction fragments of mitochondrial DNA (mtDNA) from adult anchovies from the Gulf of Mexico was employed to speciate four anchovy species. MtDNA isolated from white muscle of adult Anchoa mitchilli, A. hepsetus, A. nasuta and Engraulis eurystole produced an amplified 2.4 Kb DNA product when primers for NADH dehydrogenase 5 and 6 genes were used in polymerase chain reactions (PCR). Digestion of the amplified sequence with Dpn II produced a unique …

A System Approach To The Design Of Multirate Filter Banks., Jian Huang Jan 1998

A System Approach To The Design Of Multirate Filter Banks., Jian Huang

LSU Historical Dissertations and Theses

This dissertation studies the design of multirate filter banks by adopting a so-called system approach. The design issue of Johnston's method is first investigated in which an explicit expression of the reconstruction error is derived using Lyapunov stability theory, and new convergent iterative algorithms are proposed through non-linear optimization. The results are extended to the two-dimensional filter banks. The design issue of more general multirate filter banks is also investigated through model matching method. Using standard results from modern control theory, new design algorithms are developed which minimize the reconstruction error while completely eliminating the aliasing error. State-space realizations, inner-outer …

A Study Of The Influence Of Text In Morten Lauridsen's "Mid-Winter Songs"., Margaret Sue Hulley Jan 1998

A Study Of The Influence Of Text In Morten Lauridsen's "Mid-Winter Songs"., Margaret Sue Hulley

LSU Historical Dissertations and Theses

A close examination of any composer's work may yield a revealing picture of the importance placed on text by the composer. This paper focuses on the relationship between poetry and music in Morten Lauridsen's Mid-Winter Songs, settings of five poems of English poet Robert Graves. Chapter One's biography of Morten Lauridsen contains the history of Mid-Winter Songs, from its commission to its present form. The biography of Graves emphasizes those elements in his life that are referred to in the poems of Mid-Winter Songs. Chapter Two demonstrates how the texts of Mid-Winter Songs share a common vocabulary of poetic imagery; …

Meandering Processes And Channel Morphology In The Lower Mississippi River Prior To Major Human Disturbance., Paul Franklin Hudson Jan 1998

Meandering Processes And Channel Morphology In The Lower Mississippi River Prior To Major Human Disturbance., Paul Franklin Hudson

LSU Historical Dissertations and Theses

Although the Lower Mississippi River has been intensively studied, few studies have investigated meandering processes in the river when the channel was considered to be relatively free of major human disturbance. This research is significant in that it provides a detailed examination of meandering processes and channel adjustment in a large fine-grained alluvial setting, offering a departure from the base of knowledge on this topic that has evolved from studies on smaller coarse-grained river systems. The study spans the entire length of the Lower Mississippi River (1,704 km), from Cairo, IL to Head of Passes, LA. Two sets of hydrographic …

Dame Ethel Smyth's Concerto For Violin, Horn, And Orchestra: A Performance Guide For The Hornist., Janiece Marie Luedeke

LSU Historical Dissertations and Theses

Dame Ethel Smyth's Concerto for Violin, Horn, and Orchestra (1927) is a welcome addition to the horn concerto repertory. Moreover, Smyth's "Double Concerto" has the added distinction of being the first significant piece for horn by a female composer. The Double Concerto was first performed May 5, 1927, in the Queens Hall, London by the renowned Aubrey Brain, horn, and Jelly d'Aranyi, violin, with Sir Henry Wood conducting. The Concerto consists of three movements, each featuring beautiful thematic material that is expanded and exchanged between the two soloists and within the orchestra. The Finale is a heroic movement that makes …

Aflatoxin B(1) And Fumonisin B(1) Co-Contamination: Interactive Effects, Possible Mechanisms Of Toxicity, And Decontamination Procedures., Rebeca Lopez-Garcia

LSU Historical Dissertations and Theses

The current study evaluated interactions between the mycotoxins aflatoxin B$\sb1$ (AFB$\sb1$) and fumonisin B$\sb1$ (FB$\sb1$) in pure systems as well as in corn. During storage at 25$\sp\circ$C with high moisture (ca. 50%), corn contaminated with Aspergillus flavus (L13) and/or Fusarium moniliforme (A00102) presented different aflatoxin and fumonisin levels. Toxin production/degradation varied over storage time (0-45 days). Evaluation of the mutagenicity of unifungal or bifungal corn extracts with the Salmonella/microsomal assay (tester strains TA-100 and TA-98) with metabolic activation (S9) showed positive mutagenic responses. Different ratios of pure AFB$\sb1$/FB$\sb1$ produced divergent mutagenic responses (tester strains TA-100 and TA-98) with S9. The …

Lossless Set Compression Of Correlated Information., Oleg Stanislavovich Pianykh Jan 1998

Lossless Set Compression Of Correlated Information., Oleg Stanislavovich Pianykh

LSU Historical Dissertations and Theses

Set compression allows the compression a set of similar (correlated) images more efficiently than compressing the same images independently. Currently, set compression is performed with different inter-image predictive models, that forecast the common image properties from a few reference images. With sufficient inter-image correlation, one can predict any database image from a few templates, hence avoiding inter-image redundancy and achieving much improved compression ratios. This research focused on two major aspects of this technique: the practical limits of the predictive set compression, and the theoretical estimates of the compression efficiency. This includes a review of the previous work in set …

Characterization And Modeling Of Advanced Modified Surfaces., Vadim Gennadievich Palshin Jan 1998

Characterization And Modeling Of Advanced Modified Surfaces., Vadim Gennadievich Palshin

LSU Historical Dissertations and Theses

A promising approach to surface modification involves diamondlike carbon (DLC) coatings with "functionally-graded surfaces" (FGS) as substrates. Titanium nitride substrates have a great potential as a FGS for the DLC coating, since titanium and titanium alloy surfaces processed by enhanced glow discharge nitriding develop a nitrogen concentration profile that results in gradual increase in the material hardness in the surface region. An investigation of the atomic structure of DLC films and the surface layer structure produced in the enhanced glow discharge nitriding was conducted in the course of this work. DLC and Si-DLC films were found to be mainly amorphous, …

Behavior Of Red Snapper, Lutjanus Campechanus, In Relation To Trawl Modifications To Reduce Shrimp Trawler Bycatch., Donna Reeve Rogers

LSU Historical Dissertations and Theses

Behavioral responses of young-of-the-year red snapper, Lutjanus campechanus, to alterations in water flow were examined in the laboratory and the field in an effort to facilitate their release from shrimp trawls. Experiments with red snapper, collected by divers, were conducted in a racetrack flume. Four vertical and two horizontal mesh and solid panel types were examined. Four snapper (out of 96) escaped with vertical panels and thirteen fish (out of 48) exited with horizontal panels. Escapes occurred primarily with solid panels containing 0.95-cm holes drilled at 5-cm intervals. However, snapper that escaped with solid horizontal panels frequently went back into …

The Impact Of Specialist And Multiple Dealer Market Structures On Intraday Price Formation And Bid-Ask Spread Components., David Michael Michayluk Jan 1998

The Impact Of Specialist And Multiple Dealer Market Structures On Intraday Price Formation And Bid-Ask Spread Components., David Michael Michayluk

LSU Historical Dissertations and Theses

This dissertation investigates specialist and multiple dealer markets. In the first of four essays, simultaneous trading in two market structures on the Paris Bourse is used to evaluate intraday price formation. Specialists are found to exacerbate the end of day price rise. Stock volatility and bid-ask spreads are found to be larger when a specialist is present, in contrast to existing literature that compares market structures on different exchanges. The second essay estimates the components of the bid-ask spread and trade execution costs on the Paris Bourse. Estimates of the adverse selection cost component do not resolve the conflicting findings …

Vertebrate Paleontology And Magnetostratigraphy Of The Upper Aguja Formation (Late Campanian), Talley Mountain Area, Big Bend National Park, Texas., Julia Tippins Sankey Jan 1998

Vertebrate Paleontology And Magnetostratigraphy Of The Upper Aguja Formation (Late Campanian), Talley Mountain Area, Big Bend National Park, Texas., Julia Tippins Sankey

LSU Historical Dissertations and Theses

Considerable north-south latitudinal diversification existed among vertebrate faunas along the Western Interior Seaway during the late Campanian; this has caused difficulty correlating isolated faunas, especially southern ones, which contained endemic taxa and often lack non-paleontologic age control. The Talley Mt. local fauna is a late Campanian vertebrate fauna from the upper Aguja Formation, Big Bend National Park, Texas. It is one of the southernmost late Campanian vertebrate faunas, and is one of the few associated with magnetostratigraphy. The fauna is from five channel deposits, spanning 20 meters of section, from the lower portion of the upper shale member of the …

Photoionization Studies Of Intramolecular Dynamics: A Closer Look., Chuanyong Wu Jan 1998

Photoionization Studies Of Intramolecular Dynamics: A Closer Look., Chuanyong Wu

LSU Historical Dissertations and Theses

Using synchrotron radiation as an excitation source, dispersed fluorescence measurements of two different molecular systems are presented in this dissertation with the intention to study the two fundamental aspects of shape resonances-complexity and completeness. $\rm C\sb6F\sb6$ is a relative large and complex molecule in the sense that nonradiative transitions can take place unimolecularly in the free species. The elucidation of the ionization dynamics of this molecule helps to bridge the gap from simple molecules to matter in condensed phases. In the $\rm 2a\sb{2u}\sp{-1}$ photoionization study of $\rm C\sb6F\sb6,$ the non-Franck-Condon behavior of the vibrational distributions at around 20 eV indicates …

Development And Assessment Of A Property Rights-Based Measure Of State Regulatory Climate., Ferdinand Francis Wirth Iii Jan 1998

Development And Assessment Of A Property Rights-Based Measure Of State Regulatory Climate., Ferdinand Francis Wirth Iii

LSU Historical Dissertations and Theses

States implement many of the environmental laws enacted during the last thirty years. A key policy issue is the effect of differences in state institutions and environmental policies on the location of livestock agriculture. There is widespread belief that the stringency of state environmental regulations, known as regulatory climate, is an important factor influencing the location, growth and expansion decisions of livestock agriculture. Existing regulatory climate measures are not tailored to agriculture, and their use has given mixed results. Conceptual and empirical models were developed for the U.S. aquaculture industry, based on elements of public choice and firm location theories …

Winter Season Cold Front Variability In The Southern United States., Jeffrey W. Hardy Jan 1998

Winter Season Cold Front Variability In The Southern United States., Jeffrey W. Hardy

LSU Historical Dissertations and Theses

The variability of southern United States cold fronts was examined for 29 winter seasons, with particular emphasis placed on the identification of the upper-air circulation patterns associated with months when the region experienced extremes in cold front frequencies and intensities. The influence of atmospheric teleconnection patterns on cold front variability was first examined. For the Pacific/North American (PNA) teleconnection pattern, cold front passage frequencies in Florida were found to be significantly higher (lower) during meridional (zonal) months. An examination of the North Atlantic Oscillation (NAO) revealed that cold front passage frequencies were significantly higher (lower) in western and eastern Texas …

The Behavior Of Invert Sugar In Sugar Refining., Jianmei Yu Jan 1998

The Behavior Of Invert Sugar In Sugar Refining., Jianmei Yu

LSU Historical Dissertations and Theses

Alkaline degradation of pure invert and invert in refining materials including washed sugar liquor, melt liquor and affination syrup has been investigated. The pseudo-first-order reaction kinetics of invert alkaline degradation was demonstrated for a pH range of 9.0-11.0 and a temperature range of 70-90$\sp\circ$C. In this range, rate constants of invert degradation increased 5 to 6 times with one unit increase in pH. The effects of pH and temperature on rate constants were quantified and could be expressed as: log k = 19.42 - 6712/T - 0.712pOH. Rate constants of invert alkaline degradation at different pH-temperature-base combinations calculated by this …

Down Upon The Fold: Mercenaries In The Twelfth Century., Steven Wayne Isaac Jan 1998

Down Upon The Fold: Mercenaries In The Twelfth Century., Steven Wayne Isaac

LSU Historical Dissertations and Theses

Despite the trend in recent medieval historiography which has accepted the presence of paid warriors as no longer an aberration, the role of the mercenary within and outside twelfth-century society has still escaped in-depth analysis. Such an approach, however, has the dual merit of building an understanding of the mercenary phenomenon itself and of highlighting the often overlooked social and cultural relations, structures, and breakdowns that produce men willing to fight for profit. The period 1187-1218 provides one of the earliest, richest backgrounds against which to examine the mercenary. The accelerating return of a money economy, hardening of feudal structures, …

Arthur Miller In Montreal: Cultural Transfer Of American Plays In Quebec (1965-1997)., Bernard Lavoie Jan 1998

Arthur Miller In Montreal: Cultural Transfer Of American Plays In Quebec (1965-1997)., Bernard Lavoie

LSU Historical Dissertations and Theses

In the 1960s, American plays presented in Montreal were translated in France; the following decade saw the first of American plays translated or adapted in Quebec. In the 1980s, the translative practices employed in the seventies proved the dominant mode. In the 1990s, only exceptionally has an American play been presented in a translation originating outside of Quebec. It is now the rule that all foreign plays produced in Quebec are translated in the Quebecois idiom. This translative situation has stabilized, and the translation of American plays into Quebecois reflects an established practice. The tracing and analysis of this translative …

United States Foreign Policy And Media Coverage Of Uzbekistan: A Case Study., Mardon Nigmatovich Yakubov Jan 1998

United States Foreign Policy And Media Coverage Of Uzbekistan: A Case Study., Mardon Nigmatovich Yakubov

LSU Historical Dissertations and Theses

This study reviews the impact of U.S. political interests on media coverage of Uzbekistan, a Central Asian republic which became independent after the breakup of the Soviet Union. A content analysis of coverage from 1991 to 1996 in the New York Times, Washington Post, and Los Angeles Times was compared to American government documents and pronouncements on Uzbekistan. Striking similarities between U.S. policy towards Uzbekistan and the negative interpretation of events appearing in American newspapers were found. The democracy and human rights agendas advanced by U.S. officials apparently prompted editors and reporters to focus more on these subjects, while overlooking …

Aspects Of Searching And Tunneling Behavior In Resource Utilization By The Formosan Subterranean Termite, Coptotermes Formosanus Shiraki., Justin Carl Hedlund Jan 1998

Aspects Of Searching And Tunneling Behavior In Resource Utilization By The Formosan Subterranean Termite, Coptotermes Formosanus Shiraki., Justin Carl Hedlund

LSU Historical Dissertations and Theses

Formosan subterranean termites, Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae), were acclimated with different masses of pine or no wood (control) and then allowed access to a thin sand filled tunneling chamber. As available pine increased, termite survival and food consumption increased but search tunnel volume decreased. Increased food size resulted in termites excavating fewer exploratory tunnels due to decreases in secondary and tertiary branch tunnels. An increase in food size also decreased the total length of a search tunnel network, due to decreases in primary and secondary branch order lengths. Search tunnel networks had proportionally more length devoted to primary tunnels …
