An Examination Of The Spontaneously Generated And Retold Narratives Produced By Gifted/Learning-Disabled Adolescents From An Integrated Perspective Of Language Development., Phebe Archon Hayes Jan 1993

An Examination Of The Spontaneously Generated And Retold Narratives Produced By Gifted/Learning-Disabled Adolescents From An Integrated Perspective Of Language Development., Phebe Archon Hayes

LSU Historical Dissertations and Theses

Few studies have examined the narrative abilities of gifted children with learning disabilities. This study investigated the ability of eighth-grade gifted children with learning disabilities (gifted/LD) to produce oral and written narratives by comparing their stories to those produced by gifted peers with no learning deficits (nonLD/gifted). It was hypothesized that evidence of difficulty generating the stories relative to the macrostructure (organization of ideas across sentences) and the microstructure (organization of ideas within sentences) would be exhibited by the gifted/LD population. Twenty, 13-year-old eighth-graders served as subjects in the present investigation. All were identified as gifted by their local school …

Hydrogeochemistry Of Saline Waters In Aquifers Of Tertiary And Younger Age In Northeastern Louisiana And Southeastern Arkansas., Glenn Fredrick Huff Jan 1993

Hydrogeochemistry Of Saline Waters In Aquifers Of Tertiary And Younger Age In Northeastern Louisiana And Southeastern Arkansas., Glenn Fredrick Huff

LSU Historical Dissertations and Theses

Solute source tracing using Br/Cl and $\rm\sp{87}Sr/\sp{86}Sr$ ratios indicate that the source of brackish water in the Mississippi River alluvial and Jasper aquifers of Concordia Parish, Louisiana are brines and saline waters from the Wilcox aquifer. The proximity of maximum concentrations of dissolved solids to the location of plugged and abandoned oil wells and test holes indicates that brines and saline waters have migrated upward through these oil wells and test holes. Br/Cl ratios in the Wilcox aquifer suggest dissolution of halite as a major source of dissolved solids. Apparent thermodynamic equilibrium exists between plagioclase and kaolinite, plagioclase and Na-smectite, …

Mobilization Of A Hydrophobic Organic Compound Using Surfactant For Soil Washing., Minwen Liu Jan 1993

Mobilization Of A Hydrophobic Organic Compound Using Surfactant For Soil Washing., Minwen Liu

LSU Historical Dissertations and Theses

Soil washing using surfactants is a promising alternative for the conventional pump-and-treat method of removing hydrophobic organic compounds. The interactions and the transport of the chemicals have been studied by batch and column experiments. Sodium dodecylsulfate (SDS), an anionic surfactant, and anthracene, a hydrophobic organic, were chosen as the representative surfactant and contaminant, respectively. Fine sand and native soil were used as formation media. The experimental results indicated that the maximum loss of SDS on native soil from the solution was observed when the aqueous SDS concentration was in the region of the critical micelle concentration, and this loss was …

Development And Evaluation Of An Expert System Approach To Uneven-Aged Management Of Loblolly-Shortleaf Pine Stands In The West Gulf Region., Alfredo Baptista Lorenzo

LSU Historical Dissertations and Theses

Forest managers expend significant time and effort seeking, organizing, and synthesizing information relevant to making effective forestry decisions. Oftentimes, they must rely on the knowledge and experience of human experts, a resource that is in short supply, requires many years to acquire, and is concentrated in a few individuals. This research task suggests expert systems as one viable solution to the problems of technology transfer and automating and maintaining expertise in consistent and usable form. Expert systems are practical computer programs which solve problems that were previously considered only solvable by human expertise. The expert system developed in this research, …

The Impact Of Budget Variance, Fiscal Stress, Political Turnover, And Employment Sector On Compliance Reporting Decisions., Linda Achey Kidwell Jan 1993

The Impact Of Budget Variance, Fiscal Stress, Political Turnover, And Employment Sector On Compliance Reporting Decisions., Linda Achey Kidwell

LSU Historical Dissertations and Theses

The Governmental Accounting Standards Board (GASB) established that financial reports of governmental entities should assist users in assessing accountability of politicians and bureaucracies (GASB 1987, 100.103). Auditing standards promulgated for the governmental environment similarly emphasize administrative accountability to the public. Government Auditing Standards (GAS) require auditors to determine whether a governmental entity has complied with all applicable laws and regulations. If noncompliance is found to have a material effect on the financial statements, governmental auditors are required to report it. This study examined what level of reporting auditors use and what factors contribute to a lack of consensus in reporting …

The Antecedents And Consequences Of Transformational Leadership., Andrew J. Meibaum Iii

LSU Historical Dissertations and Theses

The present study examined the relations among theoretical antecedents and consequences of transformational leadership style. Thirty hospital CEOs completed questionnaires measuring self-esteem, autonomy, need for achievement, dominance, and hospital strategy. In addition, 214 subordinates rated the leadership style of the 30 CEOs. The hypothesized links between CEO personality and transformational leadership style were not supported. Also, the hypothesized relation between transformational leadership style and organizational effectiveness was not supported. Supplemental analyses revealed a direct relation between CEO self-esteem and organizational effectiveness and between organizational strategy and organizational effectiveness. Specifically, CEO self-esteem was positively related to organizational effectiveness, and a domain-offensive …

Predicting The Movement And Retention Of Pesticides In Soils: Physical And Chemical Nonequilibrium Modeling Approaches., Liwang Ma Jan 1993

Predicting The Movement And Retention Of Pesticides In Soils: Physical And Chemical Nonequilibrium Modeling Approaches., Liwang Ma

LSU Historical Dissertations and Theses

Atrazine retention and transport in a highly aggregated Sharkey clay soil were investigated through kinetic batch experiments, miscible displacement (column transport), and mathematical modeling. Batch results indicated that atrazine retention was kinetic and adsorption-desorption was hysteretic. Adsorption and desorption isotherms were well described using the Freundlich equation (S = KC$\sp{\rm N}).$ Fitted Freundlich K was a function of reaction time and initial atrazine input concentrations, whereas fitted N was only affected by reaction time. Desorption hysteresis was quantified by the maximum difference between adsorption and desorption isotherms, and showed a linear increase with reaction time. Atrazine adsorption kinetics was successfully …

Factors Affecting The Time-Course Of Auditory Stream Segregation., Lawrence Lee Mendoza Iii Jan 1993

Factors Affecting The Time-Course Of Auditory Stream Segregation., Lawrence Lee Mendoza Iii

LSU Historical Dissertations and Theses

Auditory scene analysis refers to the process through which sounds are heard as either belonging to separate sources or as perceptually grouped together and arising from a single source. Stream segregation describes the perceptual separation of sounds, while sequential integration is a term used to describe the linking together of sounds following one another in time. This study examined the minimum duration necessary for the perception of sequentially-presented sounds to change from sequential integration to stream segregation. The experimental stimuli were sequences of alternating sounds. Auditory scene analysis was examined under conditions in which the sequential sounds differed only in …

Electron-Pair Analysis For Doubly Excited Ridge States., Lijun Zhang Jan 1993

Electron-Pair Analysis For Doubly Excited Ridge States., Lijun Zhang

LSU Historical Dissertations and Theses

We study doubly excited states of atoms and negative ions by electron-pair analysis. The two-electron Schrodinger equation is analyzed in hyperspherical coordinates, with the electrons described throughout as a pair. In contrast to the current adiabatic hyperspherical method, which reverts at large distances to a description in terms of individual electrons, the pair aspect is preserved also asymptotically. Whereas the adiabatic potential wells converge to the single ionization limit, we develop potential wells converging to the double ionization limit of the system, and doubly excited states are then viewed as eigenstates of the pair in these wells. At the simplest …

Interconnection Networks Embeddings And Efficient Parallel Computations., Emadeddin Mohamed Abuelrub

LSU Historical Dissertations and Theses

To obtain a greater performance, many processors are allowed to cooperate to solve a single problem. These processors communicate via an interconnection network or a bus. The most essential function of the underlying interconnection network is the efficient interchanging of messages between processes in different processors. Parallel machines based on the hypercube topology have gained a great respect in parallel computation because of its many attractive properties. Many versions of the hypercube have been introduced by many researchers mainly to enhance communications. The twisted hypercube is one of the most attractive versions of the hypercube. It preserves the important features …

Energy Management In Louisiana's Public School Districts., Debra T. Acosta Jan 1993

Energy Management In Louisiana's Public School Districts., Debra T. Acosta

LSU Historical Dissertations and Theses

Revenues for public education are declining and school budgets are being evaluated for ways to cut waste. The maintenance and operations budget often falls victim to the budget ax as maintenance on equipment and buildings is deferred. It may be that as a result of the deferred maintenance, school districts are actually spending more on maintenance and operations and energy than before. This study sought to determine the status of energy use in Louisiana's 66 public school districts and to determine the need for an energy management education program in those districts. Data for the 1991-92 school year were collected …

Adrian Willaert's "Musica Nova" Selected Motets: Editions And Commentary. (Volumes I And Ii)., Bradley Leonard Almquist

LSU Historical Dissertations and Theses

Adrian Willaert was a pivotal figure in Renaissance music. As a composer, he contributed significantly to the secular repertories of the madrigal, canzone villanesca, and chanson. He was possibly the first madrigal composer outside of the genre's Roman/Florentine origins. In sacred music, Willaert contributed to the development of cori spezzati, the split-choir technique, generally associated with the Venetian School, composed at least nine masses, polyphonic settings of hymns, and approximately 173 motets. In addition to his compositions in the major vocal forms of the period, Willaert made considerable contributions to the teaching of music and music theory, establishing St. Mark's …

Rewriting The Masculine: The National Subject In Modern American Drama., Francis Granger Babcock Jan 1993

Rewriting The Masculine: The National Subject In Modern American Drama., Francis Granger Babcock

LSU Historical Dissertations and Theses

This dissertation traces the development of an American masculinity, using the concept of the national subject (borrowed from Frantz Fanon), through three different stages of the American capitalism: mercantile, or market, monopoly, and corporate, or late-capitalism. It constructs a genealogy of American maleness and then examines how this genealogy was altered and reconstituted during times of economic crisis and technological innovation. It argues that successive technological revolutions in the symbolic apparatus of American culture allowed elite political and economic interests to gain consensus by deploying the national subject using various media. In the early national period Franklin and Crevecoeur used …

Comparison Of Word Recognition And Story Retelling Under The Conditions Of Contextualized Versus Decontextualized Reading Events In At-Risk Poor Readers., Linda Cain Badon Jan 1993

Comparison Of Word Recognition And Story Retelling Under The Conditions Of Contextualized Versus Decontextualized Reading Events In At-Risk Poor Readers., Linda Cain Badon

LSU Historical Dissertations and Theses

This study investigated the relative effects of two instructional approaches on reading recognition and comprehension of passages read by low-SES first grade children. It was hypothesized that use of a contextualized instructional approach (i.e., Communicative Reading Strategies) (CRS) which facilitated written language processing (i.e., vocabulary acquisition, grammatical understanding, narrative structure, and passage comprehension) within the context of oral reading would result in better internalization of a written story than would decontextualized activities (i.e., Directed Reading) (DR) targeting the same behaviors immediately preceding or following the reading of a story. The efficacy of the two treatments was measured by (1) fluency …

First Ray Joint Mobility, Pressure And Ulceration Of The First Metatarsal Head In Diabetic Patients., James Allen Birke Jan 1993

First Ray Joint Mobility, Pressure And Ulceration Of The First Metatarsal Head In Diabetic Patients., James Allen Birke

LSU Historical Dissertations and Theses

This dissertation reviews the pathomechanics of plantar ulceration in patients with diabetes mellitus, and studies the relationship between joint mobility, pressure and the location of ulceration at the first metatarsal head. Neuropathy, mechanical stress and vascular disease have been shown to be the primary causes of ulceration in patients with diabetes. Sensory neuropathy is considered the permissive cause of plantar ulceration. Plantar ulcerations do not occur without loss of sensation in the foot. Other factors including motor neuropathy, autonomic neuropathy, abnormal mechanical stress, foot deformity, joint limitation, and hyperkeratosis are considered important component causes in plantar ulceration. Autonomic neuropathy and …

Genetic Algorithms And The Satisfiability Of Large-Scale Boolean Expressions., Thomas A. Bitterman

LSU Historical Dissertations and Theses

The two new genetic methods overpopulation and bitwise expected value are introduced. In overpopulation a temporary population of size Mn (M $>$ 1) is created using genetic operators and the n children with the highest estimated fitness values are selected as the next generation. The rest are discarded. Bitwise expected value (bev) is the fitness estimation function used. Overpopulation and bitwise expected value are applied to the NP-complete problem 3SAT (a special form of Satisfiability in which the boolean expression consists of the conjunction of an arbitrary number of clauses where each clause consists of the disjunction of 3 …

Split Abelian Extensions Of Calgebras., Mark Andrew Curole Jan 1993

Split Abelian Extensions Of Calgebras., Mark Andrew Curole

LSU Historical Dissertations and Theses

It is shown that the C* algebra of a groupoid with Haar system has a natural split abelian extension. For a split abelian extension of a C* algebra it is shown that all representations of the original algebra extend to the split abelian extension. Under a reasonable assumption it is shown that states extend to a split abelian extension. Definitions for quasi-invariant and ergodic measures are given for split abelian extension of C* algebras, and it is shown when the split abelian extension is the natural extension of the C* algebra of a groupoid with Haar system that these definitions …

Subordinate Independence: A Boundary Condition On The Effectiveness Of Transformational Leadership?, Terry Michael Dockery Jan 1993

Subordinate Independence: A Boundary Condition On The Effectiveness Of Transformational Leadership?, Terry Michael Dockery

LSU Historical Dissertations and Theses

The present study hypothesized that subordinate independence would act as a boundary condition on the effectiveness of transformation leadership; that is, that independence would moderate the relationship between transformational leadership and several dependent variables. More specifically, subordinates who responded favorably to transformational leaders were expected to be low in independence. The dependent variables employed in the study included subordinate reactions to the leader (satisfaction with the leader, perceived effectiveness of the leader, and willingness to exert extra effort due to the leader), individual subordinate performance, and discretionary subordinate organizational citizenship behavior. Study results did not support the hypotheses at the.05 …

Studies On The Energy Mobilizing Hormones In Insects., Subrata Das

LSU Historical Dissertations and Theses

Chemical factors controlling the energy mobilization in three species of insects were identified, partially characterized and their role in the process of energy mobilization were studied. High performance liquid chromatographic fractions were isolated from methanolic extracts of the corpora cardiaca (CC) from the honeybee Apis mellifera, the paper wasp Polistes exclamans and the house cricket Acheta domesticus. Each species had a single active fraction that was able to elevate the lipid titer in Acheta. Pyroglutamate aminopeptidase digestion of isolated active fractions indicated that these molecules are all peptides with a terminal pyroglutamate. Methanolic extracts of CC from Apis, Polistes and …

A Multiple Objective Formulation And Algorithm For The Layout Design Of Food Processing Facilities., Francisco A. Escobar Jan 1993

A Multiple Objective Formulation And Algorithm For The Layout Design Of Food Processing Facilities., Francisco A. Escobar

LSU Historical Dissertations and Theses

A multiple objective formulation, which incorporates robustness and constraint enforcement as design criteria, is utilized to model the layout of food processing facilities. These facilities are subject to the compliance with guidelines dictated by public health agencies, changes in product mix, and variation in production levels due to seasonality, which render existing layout design algorithms unsuitable for their design. The solution of the robust multiple objective formulation is implemented using a construction heuristic algorithm, MORCH, and an improvement heuristics, MOLAD. The MORCH/MOLAD hybrid algorithm performs comparably to well known heuristic algorithms where materials handling cost is used as the only …

Corporate Restructuring And The Information Hypothesis: An Empirical Analysis., Steven Randal Ferraro Jan 1993

Corporate Restructuring And The Information Hypothesis: An Empirical Analysis., Steven Randal Ferraro

LSU Historical Dissertations and Theses

The purpose of this dissertation is to explore the motivation behind various restructuring choices within a securities issuance context. Previous theoretical models and empirical evidence suggest that three methods of restructuring--equity carve-outs, sell-offs, and spin-offs, on average, signal favorable information about parent firms. This has been interpreted as reflecting either enhanced potential for efficiency gains, positive asymmetric information about the value of industry assets, or changes in agency costs. This dissertation presents an alternative framework by relating restructuring announcements to the effects of security issuance. Empirical tests are formulated to determine if these announcements contain valuable private information about the …
