Intrinsic And Extrinsic Motivational Factors And Type A Behavior Pattern, Karen M. Ratliff, Sharon J. Hicks Jan 1998

Intrinsic And Extrinsic Motivational Factors And Type A Behavior Pattern, Karen M. Ratliff, Sharon J. Hicks

Modern Psychological Studies

In this study motivational factors were examined to determine if subjects were more intrinsically or extrinsically motivated. In addition, Type A behavior pattern was assessed to determine if a link exists between motivation and Type A behavior. A total of 176 students from a small midwestern university participated in this research. Intrinsic motivation was manipulated by using one of two movies, one interesting and one boring. Extrinsic motivation was measured by manipulating the number of extra credit points given for participation. Participants were assigned to one of four conditions: High intrinsic/low extrinsic, high intrinsic/high extrinsic, low intrinsic/low extrinsic, and low …

Influence Of Ground Cover On Spider Populations In A Table Grape Vineyard, Michael J. Costello, Kent M. Daane Jan 1998

Influence Of Ground Cover On Spider Populations In A Table Grape Vineyard, Michael J. Costello, Kent M. Daane

Horticulture and Crop Science

1. Cover crops and/or resident ground vegetation have been used in California vineyards to increase the number of predators and decrease the number of pestiferous herbivores. The most common resident predators in vineyards are spiders (Araneae). Several observational studies suggest that the addition of cover crops results in an increase in spider density and a decrease in insect pest densities. 2. To test experimentally the effects of cover crops and/or resident ground vegetation (hereafter collectively referred to as ground cover) on spider populations, a 3-year study was undertaken in a commercial vineyard. Large, replicated plots were established with and without …

Is Sound Just Noise, Joshua D. Coval, Tyler Shumway Jan 1998

Is Sound Just Noise, Joshua D. Coval, Tyler Shumway

Faculty Publications

This paper analyzes the information content of the ambient noise level in the Chicago Board of Trade's 30-year Treasury Bond futures trading pit. Controlling for a variety of other variables, including lagged price changes, trading volumes, and news announcements, we find that the sound level conveys information which is highly economically and statistically significant. In particular, we find increases in the sound level precede periods of high price volatility and increased trading volumes. Increases in the sound level also presage the placement of block trades and relative increases in customer-driven trading. Our results add to our understanding of the market …

The Physiological And Psychological Responses To Submaximal Exercise At Different Times In Renal Disease Patients., Marta Amaral-Melendez Jan 1998

The Physiological And Psychological Responses To Submaximal Exercise At Different Times In Renal Disease Patients., Marta Amaral-Melendez

LSU Historical Dissertations and Theses

This study investigated cardiorespiratory, hematological, and psychological responses to acute submaximal exercise, and recovery in end stage renal disease patients. Five African-American males on hemodialysis, were randomly assigned to three exercise treatments (30 minutes on the treadmill at 60% VO$\sb2$ peak): pre dialysis (2 hours before), post dialysis (1 hour after), and off dialysis (24 hours after last dialysis). The cardiorespiratory (CR) variables were: ventilation (V$\sb{\rm E}$), oxygen consumption (VO$\sb2$), carbon dioxide production (VCO$\sb2$), respiratory exchange ratio (R), and kilocalories (KCAL/min). The hematological variables were: blood urea nitrogen (BUN), creatinine (Cr), albumin (Al), total protein (Tp), glucose (Gl), sodium (Na$\sp{++}$), …

Form: The Fortran Object Recovery Model. A Methodology To Extract Object-Oriented Designs From Imperative Code., Bonnie Lynn Achee

LSU Historical Dissertations and Theses

A majority of legacy systems in use in the scientific and engineering application domains are coded in imperative languages, specifically, COBOL or FORTRAN-77. These systems have an average age of 15 years or more and have undergone years of extensive maintenance. They suffer from either poor documentation or no documentation, and antiquated coding practices and paradigms (Chik94) (Osbo90). The purpose of this research is to develop a reverse-engineering methodology to extract an object-oriented design from legacy systems written in imperative languages. This research defines a three-phase methodology that inputs source code and outputs an object-oriented design. The three phases of …

The Interactions Among The Subunits Of The Mcrbc Restriction System In E. Coli., Loganayaki Ganesh Jan 1998

The Interactions Among The Subunits Of The Mcrbc Restriction System In E. Coli., Loganayaki Ganesh

LSU Historical Dissertations and Theses

The McrBC system of Escherichia coli K12 restricts DNA containing modified cytosines within specific sites. The modified cytosines recognized may be 5-hydroxymethylcytosine, N$\sp4$-methylcytosine or 5-methylcytosine. In the mcrBC operon, the mcrB gene is expressed to produce the McrB$\sb{\rm L}$ protein (51 kDa) and the McrB$\sb{\rm S}$ protein (33kDa), which is translated from an inframe internal translation start site and lacks the N-terminal 161 amino acids of the long product. The McrC protein is a 39kDa protein and is required for the cleavage of most methylated substrates. Using a MalE-McrB$\sb{\rm L}$ fusion protein, the endonucleolytic McrB$\sb{\rm L}$ subunit was shown to …

Detection Of Mechanisms Of Profenofos Resistance In The Tobacco Budworm, Heliothis Virescens (F.)., John Ambrose Harold Jan 1998

Detection Of Mechanisms Of Profenofos Resistance In The Tobacco Budworm, Heliothis Virescens (F.)., John Ambrose Harold

LSU Historical Dissertations and Theses

Biochemical and physiological mechanisms of profenofos resistance in laboratory and field populations of the tobacco budworm, Heliothis virescens (F.) were studied. High frequencies of profenofos resistance were recorded in all field-collected strains and were strongly correlated with esterase (EST) activity and moderately correlated with glutathione S-transferase activity. Mean levels of acetylcholinesterase (AChE) sensitivity to inhibition by chlorpyrifos oxon were lower in some field strains than levels in an insecticide-susceptible strain; however, AChE sensitivity and resistance were poorly correlated in all field strains. There was no correlation between resistance and the activities of P450-monooxygenase or glutathione S-transferase measured. Studies with laboratory-selected …

Evolutionary Effects Of Irradiation In Cataclysmic Variables., Patrick Joseph Mccormick Jan 1998

Evolutionary Effects Of Irradiation In Cataclysmic Variables., Patrick Joseph Mccormick

LSU Historical Dissertations and Theses

We developed a simple stellar computational model consisting of two concentric polytropic shells in order to investigate compact binary evolution. In this thesis we focus the investigation on the effects of irradiation on the orbital evolution of cataclysmic variables (CVs). In these systems, when the companion is illuminated by a fraction of the accretion luminosity, the orbital evolution consists of irradiation-driven limit cycles on thermal timescales. These cycles are superimposed on the secular evolution toward shorter periods due to systemic angular momentum losses. When the irradiation instability is enhanced by consequential angular momentum losses $j\sb{\rm CAML}$ the net effect is …

An Exploratory Study Of The Consumer Behavior Of Working Adolescent Females., Diane Denais Sasser Jan 1998

An Exploratory Study Of The Consumer Behavior Of Working Adolescent Females., Diane Denais Sasser

LSU Historical Dissertations and Theses

Employment of high school students has been growing steadily since the mid-1960s (Cole, 1991). Today, more than 40% of all high school students who work are employed at least part-time (U.S. Bureau of Labor Statistics, 1995). Working adolescents may view their earnings as a sudden windfall of income to be used as discretionary income. This "premature affluence" may reinforce inappropriate consumer behaviors such as spending beyond means which may become established habits into their adult lives (Bachman, 1983). The cognitive development of these adolescents may be at the concrete operational thinking stage which inhibits them from handling adult behaviors in …

Purification And Antioxidant Properties Of Rice Bran (Gamma)-Oryzanol Components., Zhimin Xu Jan 1998

Purification And Antioxidant Properties Of Rice Bran (Gamma)-Oryzanol Components., Zhimin Xu

LSU Historical Dissertations and Theses

A high purity $\gamma$-oryzanol was obtained from crude rice bran oil using a normal phase preparative scale HPLC. It was used in implementing a reverse phase HPLC method for separating each individual component of $\gamma$-oryzanol present in rice bran oil. Ten fractions were isolated in the reverse phase HPLC method. The ten components of $\gamma$-oryzanol were identified. Three of these, cycloartenyl ferulate, 24-methylene cycloartanyl ferulate, and campesteryl ferulate, were major components of $\gamma$-oryzanol. The yield of $\gamma$-oryzanol without saponification was significantly higher than that with saponification in solvent extraction. The solvent mixture with 50% hexane and 50% isopropanol (v/v.) at …

The Structure And Stability Of Selected, 2-D Self-Gravitating Systems., Saied W. Andalib Jan 1998

The Structure And Stability Of Selected, 2-D Self-Gravitating Systems., Saied W. Andalib

LSU Historical Dissertations and Theses

Models of radially and vertically extended self-gravitating disks orbiting around a central point mass are relevant to the dynamics of astrophysical systems and are thought to be common in many galaxies. The gravity driven instabilities in these accretion disks are now believed to be a possible mechanism for star formation via disk fragmentation (Shu, Adams, & Lizano 1987, Adams, Rudin & Shu 1989; Christodoulou 1995). We quantify these regions of instability using a simple toroidal model of an accretion disk. We choose the two-dimensional axisymmetric, incompressible slender disks to examine and map out these principal modes of gravity driven instabilities. …

Identification Of Antigens Of Edwardsiella Ictaluri, The Causative Agent Of Enteric Septicemia Of Catfish (Esc)., Michelle Marie Moore

LSU Historical Dissertations and Theses

Edwardsiella ictaluri, causative agent of enteric septicemia of catfish (ESC), is the primary bacterial pathogen of commercially produced channel catfish (Ictalurus punctatus). The purpose of this study was to make progress towards development of a successful ESC vaccine by generating and characterizing a pool of E. ictaluri antigens and determining if they were protective against ESC in catfish. Antigenic protein expression was evaluated in E. ictaluri cells under different conditions of growth using two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) and western blotting with pooled convalescent catfish serum (CCS). Results showed protein bands separated by one-dimensional PAGE may consist of one or …

Structural Characterization Of Beta Carbonic Anhydrases From Higher Plants., Michael H. Bracey Jan 1998

Structural Characterization Of Beta Carbonic Anhydrases From Higher Plants., Michael H. Bracey

LSU Historical Dissertations and Theses

It is the goal of this dissertation research to reveal some aspects of the physical nature of spinach carbonic anhydrase as a representative $\beta$CA using the techniques of sequence comparison, molecular biology, and biophysics. Though both $\alpha$ and $\beta$ carbonic anhydrases are zinc dependent metalloenzymes, it is clear that the two isoforms do not adopt the same mechanism for coordinating the active site metal. While $\alpha$CA binds zinc through three histidine ligands, $\beta$CA cannot due to a lack of evolutionarily conserved histidines. Instead, the $\beta$ family has adopted a ligand scheme incorporating a single histidine and two cysteines. This has …

Microstructure Evolution And Its Influence On Thermal Expansion And Tensile Properties Of The Superalloy In738lc At High Temperatures., Ercan Balikci Jan 1998

Microstructure Evolution And Its Influence On Thermal Expansion And Tensile Properties Of The Superalloy In738lc At High Temperatures., Ercan Balikci

LSU Historical Dissertations and Theses

Three major aspects of the superalloy IN738LC are studied in this dissertation: (i) precipitate microstructure evolution, (ii) tensile mechanical properties, and (iii) thermal expansion characteristics. IN738LC is a Ni-base, $\gamma\sp\prime$ Ni$\sb3$Al(Ti) precipitate-strengthened alloy. This alloy includes $\sim$20-43 volume % $\gamma\sp\prime$ and also some (Ta,Ti)C at the grain boundaries and in the matrix. Different heat treatments were carried out to study the precipitate evolution mechanisms and kinetics in this superalloy. It was found that the proper solution treatment producing the single-phase supersaturated solid solution condition is 1235$\sp\circ$C/4h/WQ. Solution treatment at 1200$\sp\circ$C/4h/WQ, however, produces a refined precipitate microstructure. Aging treatments after both …

Locus Of Reform: From Reflection To Effectiveness Through The Voices Of Novice Teachers., Patricia Babin Caillouet

LSU Historical Dissertations and Theses

This descriptive multiple-case qualitative study focused on the professional and personal experiences of five novice teachers--three preservice student teachers and two first-year teachers. Research conducted in two exemplary elementary schools examined the following questions: (a) How do preservice and first-year teachers use reflective practice and self-assessment to develop effective teaching practices? (b) How do the preservice and first-year teachers' approaches to effective literacy instruction compare? (c) Why does reflection not translate into effectiveness? and (d) How is effectiveness perceived in the professional, social school environment of novice teachers? Results of the case studies determined that teacher education programs must go …

An Investigation Of The Relationship Between Teachers' Orientations In Reading Process And Instruction: Four Case Studies., Carrice Lou Cummins

LSU Historical Dissertations and Theses

The beliefs that teachers hold about how children learn are often reflected in the instructional practices they use to help children become readers. The purpose of this study was threefold: (a) to identify teachers' beliefs regarding how reading takes place and how reading develops, (b) to examine the instructional reading practices implemented in teachers' classrooms, and (c) to explore the relationships between teachers' theoretical beliefs and their instructional practices in providing appropriate reading instruction. Qualitative methods informed this study by providing case studies of four primary grade teachers, giving detailed accounts of their theoretical beliefs--process and instruction. Two of the …

Supplemental Organic Chromium For Dairy Calves., Christopher L. Depew Jan 1998

Supplemental Organic Chromium For Dairy Calves., Christopher L. Depew

LSU Historical Dissertations and Theses

In Exp. 1, 42 calves were fed milk replacer and then starter either with or without 1 ppm supplemental chromium (Cr) as Cr-picolinate. Neither Cr nor sex affected growth performance. With the exception of plasma nonesterified fatty acid concentrations (NEFA), weekly plasma metabolites were not affected by Cr or sex. Pre- and postfeeding plasma NEFA concentrations were lower in Cr-fed calves, but were not affected by sex. AU calves seemed to become less insulin sensitive with age, as plasma glucose became lower and insulin higher as calves became older. During i.v. glucose tolerance tests (IVGTT), calves cleared glucose faster at …

Techniques For Resolving Incomplete Systems In K-Systems Analysis., Gary J. Asmus Jan 1998

Techniques For Resolving Incomplete Systems In K-Systems Analysis., Gary J. Asmus

LSU Historical Dissertations and Theses

K-systems analysis is a generalization of reconstructability analysis (RA), where any general, complete multivariate system (g-system) can be transformed into an isomorphic, dimensionless system (a K-system) that has sufficient properties to be analyzed using probabilistic RA algorithms. In particular, a g-system consists of a set of states formed from a complete combination of the variables assigned specific values from a finite set of possible values and an associated system function value. The g-system must be complete in that all possible states must have an associated system function value. K-systems analysis has been applied to a variety of systems, but many …

An Analysis Of Factors Influencing The Teaching Of Biological Evolution In Louisiana Public Secondary Schools., Donald Wayne Aguillard Jan 1998

An Analysis Of Factors Influencing The Teaching Of Biological Evolution In Louisiana Public Secondary Schools., Donald Wayne Aguillard

LSU Historical Dissertations and Theses

Louisiana public school biology teachers were surveyed to investigate their attitudes toward biological evolution. A mixed method investigation was employed using a questionnaire and open-ended interviews. Results obtained from 64 percent of the sample receiving the questionnaire indicate that although teachers endorse the study of evolution as important, instructional time allocated to evolution is disproportionate with its status as a unifying concept of science. Two variables, number of college courses specifically devoted to evolution and number of semester credit hours in biology, produced a significant correlation with emphasis placed on evolution. The data suggest that teachers' knowledge base emerged as …
