Modifying Risk Perceptions Of Japanese University Students Using A Culturally Compatible Mode Of Instruction, Susan F. Walsh May 1999

Modifying Risk Perceptions Of Japanese University Students Using A Culturally Compatible Mode Of Instruction, Susan F. Walsh

Graduate Theses, Dissertations, and Problem Reports (ETD)

Japanese university students who come to the United States present a particular challenge to universities to teach them about their risks to personal property. The usual method of delivering this message, a lecture during the orientation period, may not be the most effective way of presenting the information due to their limitations in understanding English. It was hypothesized that a manga, or comic book, would be an effective and culturally compatible mode of instruction.;A manga was developed and was tested on a group of incoming Japanese freshmen. Forty students (12 females, 28 males) were divided into two groups. One group …

In -Cylinder Combustion -Based Virtual Emissions Sensing, Michael L. Traver May 1999

In -Cylinder Combustion -Based Virtual Emissions Sensing, Michael L. Traver

Graduate Theses, Dissertations, and Problem Reports (ETD)

The development of a real-time, on-board measurement of exhaust emissions from heavy-duty engines would offer tremendous advantages in on-board diagnostics and engine control. In the absence of suitable measurement hardware, an alternative approach is the development of software-based predictive approaches. This study demonstrates the feasibility of using in-cylinder pressure-based variables as the inputs to predictive neural networks that are then used to predict engine-out exhaust gas emissions. Specifically, a large steady-state engine operation data matrix provides the necessary information for training a successful predictive network while at the same time eliminating errors produced by the dispersive and time-delay effects of …

Regulation Of The Synthesis And Protein Stability Of The Alternative Sigma Factor Rpos In Salmonella Typhimurium, Christofer Lee Cunning May 1999

Regulation Of The Synthesis And Protein Stability Of The Alternative Sigma Factor Rpos In Salmonella Typhimurium, Christofer Lee Cunning

Graduate Theses, Dissertations, and Problem Reports (ETD)

RpoS is an alternative sigma factor which is required for the expression of genes that help bacteria cope with environmental stress. The regulation of RpoS is multifactorial and occurs at the levels of synthesis and protein turnover. Our lab has previously identified a rpoS translation enhancing factor in Salmonella typhimurium, the RNA-binding protein HF-I. An antisense element consisting of rpoS mRNA secondary structure is predicted to sequester the rpoS ribosome binding site and inhibit translation. HF-I may interact with this element to increase translation. Using rpoS genetic fusions, we have shown that native rpoS promoters can be substituted with tac …

Assessing The *Discriminative Properties Of Response -Reinforcer Relations Using Concurrent Schedules Of Reinforcement, Josue P. Keely

Graduate Theses, Dissertations, and Problem Reports (ETD)

The discriminative properties of schedules of reinforcement have been assessed by making a choice response conditional upon some aspect of the schedule that produced the choice component. The discriminative properties of concurrent schedules of reinforcement and the effect of disruptions in the response-reinforcer relation were investigated using conditional-discrimination procedures. In the first experiment, choice components were produced by responding to one of two variable-interval (VI) schedules. Disruptions in the temporal contiguity between a VI response and a choice component were introduced by arranging a percentage of choice components according to a variable-time schedule. Choice responding was a function of the …

Regulation Of Heme Biosynthesis Targets The Key Enzyme Hema By A Mechanism Of Protein Stabilization In Salmonella Typhimurium, Liying Wang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Heme serves as a cofactor of cytochromes and catalases. It is essential for energy generation and in defense against toxic hydrogen peroxide in nearly all cells including Salmonella typhimurium and Escherichia coli. Indirect evidence has suggested that heme synthesis is a regulated process. Little is known about how heme synthesis is regulated in enteric bacteria even though the heme synthetic pathway is genetically well-defined. This research represents the first report that heme synthetic regulation affects the first committed heme pathway enzyme, glutamyl-tRNA reductase (HemA), by an unusual mechanism.;HemA, encoded by hemA gene, catalyzes the rate-limiting step of heme biosynthesis.

The Effects Of Teacher Clarity And Immediacy On Student Learning, Apprehension, And Effect., Joseph Lee Chesebro Jan 1999

The Effects Of Teacher Clarity And Immediacy On Student Learning, Apprehension, And Effect., Joseph Lee Chesebro

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study examined the effects clear and immediate teaching have on student learning, state receiver apprehension, and affect. Although teacher clarity and constructs conceptually similar to immediacy have been identified as effective teaching behaviors, few experimental studies have investigated the combined use of these behaviors. This is important because research related to clear teaching suggests that immediacy may be a necessary precursor to clear teaching and that the absence of immediacy may significantly threaten the effectiveness of clear messages. A review of this research is followed by the identification of attributes which characterize clear teachers. The results indicate that clarity, …

Programming Wizards: Generating Syntax-Free Conceptual Editors., Windell Hansford Goff Ii

Graduate Theses, Dissertations, and Problem Reports (ETD)

The objective of this project is to develop a generator for a class of syntax-free conceptual editors called "programming wizards". These editors provide a model of software that is especially suitable for novice software developers, freeing them from intricate syntactic details. The effectiveness of these editors is demonstrated by showing how they ease learning of component-based software engineering principles in introductory computer science classrooms. The notion of programming wizard generation is expected to be generally applicable for teaching other principles without the intrusiveness of particular specification / programming syntax.

Acoustic Signal During Hydraulic Fracturing., Jeremy Scott King Jan 1999

Acoustic Signal During Hydraulic Fracturing., Jeremy Scott King

Graduate Theses, Dissertations, and Problem Reports (ETD)

Well performance analysis using pressure/time data are historically collected over a time span of minutes and hours. Such pressure/time performance is controlled by Darcy type fluid seepage, and used to define the formation boundaries and permeability. A different pressure transient is used to determine the acoustic characteristics of the open flow passages of a well. A pressure transient can be induced by a sudden change in flow rate. The wave travels towards the casing perforations and back to the surface. The reflected signal contains the piping and fracture acoustic signature within it. The transient signal lasts less than a minute. …

A Study Of Protein Interactions By Electrospray Ionization Mass Spectrometry., Weiling Zhang Jan 1999

A Study Of Protein Interactions By Electrospray Ionization Mass Spectrometry., Weiling Zhang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Electrospray Ionization Mass Spectrometry is gaining recognition as a powerful tool for the study of proteins. It is a “soft” ionization source, which permits the preservation of noncovalent interactions prevailing in biological systems. It is able to form multiply charged ions, which facilitates analyses of very large molecules. The change of the protein conformations can be investigated by charge state distribution shifts in ESI-MS. The noncovalent interactions of proteins with other molecules can also be studied by ESI-MS because these interactions often change the shape of proteins. I examined the effect of various operating parameters on shape of the ESI-MS …
