Cognitive Strategy Training Effects On Reading Comprehension In Learning-Disabled Readers., Erin Cuccia Agostini Jan 1987

Cognitive Strategy Training Effects On Reading Comprehension In Learning-Disabled Readers., Erin Cuccia Agostini

LSU Historical Dissertations and Theses

This study was conducted to investigate the hypothesis that learning disabled children with reading deficits demonstrate a "production deficiency" by failing to spontaneously employ appropriate cognitive strategies in reading situations. Moreover, it was anticipated that providing them with explicit instruction regarding these strategies would improve their comprehension. Thirty learning disabled seventh- and eighth-grade students were randomly assigned to one of three training conditions: (a) summarization, (b) self-questioning, and (c) control. The effectiveness of the training strategies was assessed by having students write an 80-word summary and answer a 10-item multiple choice comprehension test on each of two passages during three …

Molecular Cloning And Sequencing Of The Bacillus Stearothermophilus 6-Phosphofructo-1-Kinase Gene And Of A Partial Rabbit Muscle 6-Phosphofructo-1-Kinase Complementary-Dna., Brent Arthur French

LSU Historical Dissertations and Theses

A system is presented for determining the relationships between structure and function in the allosteric enzyme 6-phosphofructo-1-kinase (PFK). The ATP-dependent phosphorylation of fructose 6-phosphate to fructose 1,6-bisphosphate catalyzed by PFK is the first reaction unique to the glycolytic pathway. The structure-function relationships in PFK can now be addressed by site-specific mutagenesis. This is a method for directly testing hypotheses concerning the functions of individual amino acids in a protein molecule. The main body of this dissertation is composed of three sections. The first two sections describe the development of a system by which the structure-function relationships in Bacillus stearothermophilus PFK …

The Effect Of Vocal Modeling On Pitch-Matching Accuracy Of Children In Grades One Through Six., Georgia A. Green Jan 1987

The Effect Of Vocal Modeling On Pitch-Matching Accuracy Of Children In Grades One Through Six., Georgia A. Green

LSU Historical Dissertations and Theses

The purpose of this study was to investigate the effect of adult female, adult male, and child vocal modeling on the pitch-matching accuracy of children in grades one through six. Because singing is a basic component of the elementary music curriculum and is a skill which a child will continue to use throughout his/her life, it is important to determine how a child can most successfully develop and use his/her singing voice. Existing literature indicates that those factors which most directly affect a child's singing ability are maturation, auditory discrimination, vocal range, and vocal modeling. Conflicting results exist as to …

Parameters Of Peat Formation In The Mississippi Delta (Holocene)., Elisabeth Catharina Kosters Jan 1987

Parameters Of Peat Formation In The Mississippi Delta (Holocene)., Elisabeth Catharina Kosters

LSU Historical Dissertations and Theses

The Mississippi Delta consists of six major Holocene deltaic complexes, that each had a life-span of about 1500 years. Emphasis of this study is on autochthonous peats of Barataria Basin, a large-scale interdistributary basin, between levees of the LaFourche and St. Bernard/Plaquemine deltas. A 6 m. thick set of lithostratigraphic units constitutes the aggradational basin-fill. Organic-rich beds occur in three phases, each representing an accumulating period that was interrupted by subsidence and the influx of detrital clastics from renewed nearby fluvio-deltaic sedimentation. Peats accumulated in eutrophic, non-domed environments in fresh water swamps and (often floating) marshes and average 81.7% organic …

The Rabbit Phosphofructokinase Genes: Molecular Cloning, Sequencing And Characterization., Ming-Ching Kao

LSU Historical Dissertations and Theses

Two rabbit phosphofructokinase (PFK) genomic clones were isolated from a lambda Charon 4A rabbit liver DNA library. A 180-bp rabbit muscle PFK cDNA encoding 60 amino acids in the C-terminal region of RM-PFK was used as a probe. By using the shotgun subcloning approach, we cloned, sequenced and characterized two rabbit PFK genomic clones. The two clones overlapped and represented a total length of 17 kb which encoded the entire RM-PFK protein. The organization of this gene was elucidated by restriction mapping and DNA sequencing. It contains 22 exons, ranging in size from 45 to 190 bp, separated by 21 …

Spacing Of Repetitions And Contextual Interference Effects In Motor Skill Learning., Harry John Meeuwsen Jan 1987

Spacing Of Repetitions And Contextual Interference Effects In Motor Skill Learning., Harry John Meeuwsen

LSU Historical Dissertations and Theses

Three experiments are reported that examined the possibility that the contextual interference effect in motor skill learning is a variation of a multiple trial spacing of repetitions effect. Specifically, the question why a non-spaced condition in a spacing of multiple trials motor learning paradigm has not produced predicted retention deficits. Subjects in all experiments learned to perform a simple motor skill in a criterion movement time. Experiments 1 and 2 examined why spacing of multiple trials did not produce expected retention performance benefits in previous spacing experiments. The results of Experiment 1 and 2 showed that the randomness of the …

An Investigation Of The Inference And Mapping Components Of The Componential Theory Of Analogical Reasoning., Catherine Sheard Jan 1987

An Investigation Of The Inference And Mapping Components Of The Componential Theory Of Analogical Reasoning., Catherine Sheard

LSU Historical Dissertations and Theses

Sternberg's componential theory of analogical reasoning (1977) provides a series of steps that may be followed in order to solve analogies. According to Sternberg, when given a simple analogy (in the form A:B::C: (D$\sb1$, D$\sb2$, D$\sb3$)) the reasoner: (a) encodes the terms of the analogy, (b) infers the relation between A and B, (c) maps the relation between A and C, (d) applies a relation analogous to the inferred one from C to each answer option, choosing the closer option, and (e) responds. The purpose of this research was to further investigate the inference and mapping processes of the componential …

Raison D'Etat And The American Philosophy Of Realism In World Affairs. (Volumes I And Ii)., Gregory T. Russell Jan 1987

Raison D'Etat And The American Philosophy Of Realism In World Affairs. (Volumes I And Ii)., Gregory T. Russell

LSU Historical Dissertations and Theses

The purpose of this study is to determine the extent to which the heritage of political thought shaping European raison d'etat is significant for the theory and practice of post-World War II realism in American foreign policy. Analysis is guided by the hypothesis that the response of postwar realists to the issues raised by an interdependent multistate system differs from the traditional rationale of raison d'etat intended for a Eurocentric international society characterized by common diplomatic objectives and values. Consideration is given to how the continental legacy has been modified and adapted by realist spokesmen to the exigencies of America's …

Insulin Receptors Of Erythrocytes And Liver Membranes In Dogs., Karen Johnson Wolfsheimer Jan 1987

Insulin Receptors Of Erythrocytes And Liver Membranes In Dogs., Karen Johnson Wolfsheimer

LSU Historical Dissertations and Theses

Insulin receptor assays using canine liver membranes and erythrocytes were validated for use in evaluating insulin receptor binding parameters within a healthy population of dogs. Association, dissociation, saturability and specificity were demonstrated for insulin receptors of canine liver membranes and erythrocytes. Assay precision was evaluated by measuring interassay coefficient of variation (liver membrane = 25.0%; erythrocytes = 9.3%). Because the number of high-affinity receptor sites and high-affinity K$\sb{\rm D}$ were determined using physiological concentrations of insulin, they were considered to be more physiologically important than the total number of receptor sites, low-affinity K$\sb{\rm D}$ and Ke, which were derived using …

Feeding And Microspatial Relationships Of Meiobenthic Harpacticoid Copepods With Microbial Flora., Alan William Decho Jan 1987

Feeding And Microspatial Relationships Of Meiobenthic Harpacticoid Copepods With Microbial Flora., Alan William Decho

LSU Historical Dissertations and Theses

Feeding processes and their relationship to microspatial patterns were examined for several harpacticoid species. Field evidences and laboratory radiolabel experiments suggest that diatoms comprise a major portion of the food resources ingested by harpacticoids. Bacteria and mucus-exopolymer secretions (associated with the bacteria and diatoms) are also ingested, coincidently while ingesting diatoms. Also, significant ontogenetic shifts in food resource utilization occur from naupliar to adult stages. Field grazing rate studies were conducted on an intertidal mudflat over different portions of a tidal cycle using several harpacticoid species (Scottolana canadensis, Microarthridion littorale, Paronychocamptus huntsmani). Highest grazing rates for S. canadensis occurred just …

An Experimental Investigation Into Carbon-Dioxide-Induced Organic Deposition., Josh Chia-Hsine Fu Jan 1987

An Experimental Investigation Into Carbon-Dioxide-Induced Organic Deposition., Josh Chia-Hsine Fu

LSU Historical Dissertations and Theses

Wettability change (or a relative permeability effect) has long been considered a mechanism for enhanced oil recovery. Reports show that adsorption of petroleum heavy ends, mainly asphaltenes and resins, onto a rock surface can alter its wettability. Reports also show that high concentrations of CO$\sb2$ will induce the formation of a solid phase in CO$\sb2$/crude mixtures. However, the propensity of a reservoir system for CO$\sb2$-induced hydrocarbon precipitation and how this deposition affects the rock wettability has not been yet investigated. Once variables such as oil composition, pressure, temperature, brine chemistry, and surface mineralogy are adequately defined it becomes possible to …

Regulation Of Dextransucrase Secretion By Proton Motive Force In Leuconostoc Mesenteroides., David Roland Otts Jan 1987

Regulation Of Dextransucrase Secretion By Proton Motive Force In Leuconostoc Mesenteroides., David Roland Otts

LSU Historical Dissertations and Theses

The relationship between proton motive force and the secretion of the enzyme dextransucrase (E.C. 2.4.1.5) in Leuconostoc mesenteroides was investigated. The transmembrane pH gradient was determined by measurement of the uptake of radiolabeled benzoate or methylamine while the membrane potential was determined by measurement of the uptake of radiolabeled tetraphenylphosphonium bromide. Leuconostoc mesenteroides was able to maintain a constant proton motive force of $-130$ mV when grown in fermenters at constant pH while a value of $-140$ mV was determined from concentrated cell suspensions. The contribution of the membrane potential and transmembrane pH gradient to the proton motive force varied …

A Rhetorical Analysis Of Selected Republican Speeches In The 1856 Presidential Election Campaign., Linda Jean Webster Jan 1987

A Rhetorical Analysis Of Selected Republican Speeches In The 1856 Presidential Election Campaign., Linda Jean Webster

LSU Historical Dissertations and Theses

The Republican party organized its first presidential campaign in 1856. The party was composed of men from a wide variety of political backgrounds, primarily from free soil and anti-slavery groups. The rhetoric of this first Republican campaign represented the efforts of these individual speakers to reconcile their free soil arguments with the official party platform. Although the party was loosely organized and poorly funded, many respected orators participated in the campaign. As background for the rhetorical analysis, the major political and historical events of the decade are identified in the first two chapters. Bleeding Kansas, abolitionism, and the reorganization of …

The Management Of Dying: Tasks And Social Relationships In Patient Care., Jeffrey Michael Clair Jan 1987

The Management Of Dying: Tasks And Social Relationships In Patient Care., Jeffrey Michael Clair

LSU Historical Dissertations and Theses

A grounded theory approach guides the interpretation of observational, semi-structured interviews, content analysis, and taped discourse data collected from a 48 bed oncology unit with 288 study patients. Data are presented to explicate generated concepts of regressive intervention and the dying role. Data indicate that when physicians no longer perceive their goals of cure achievable, they distance themselves from patients. Physicians use certain devices to facilitate this gradual or abrupt, but purposeful, withdrawal from patients' curative regimens. These devices are specified in discourse transcripts as use of the medical record, silence, and alternative interactions (family members). Physician-authority, cautious optimistic conversational …

A Supply Response Model For Rice And Soybeans In The Mississippi Delta., David Leon Hoppenstedt Jan 1987

A Supply Response Model For Rice And Soybeans In The Mississippi Delta., David Leon Hoppenstedt

LSU Historical Dissertations and Theses

This study examines the economic sources of variation in the supply of rice and soybeans in the Mississippi Delta. As farmers alter their land allocations to various crops, they cause fluctuations in the supply of agricultural products. Traditional theory posits that acreage planted is a function of lagged prices, but does not explicitly recognize some technological constraints. One prevalent technological constraint is that the monocropping of particular crops results in a significant decrease in land productivity. The model in this study attempts to improve the specification of the technological constraint of declining soil productivity due to monocropping. Two different statistical …
