A Causal-Comparative Study Of The Relationship Of Mathematics, Science, Athletics And The Career Expectations Of Adolescent Women, Elwood Martin Bowers

Dissertations

The premise of this study is that high school women who complete course work in advanced mathematics and advanced science and participate in organized athletic programs will develop skills, knowledge, and attitudes that facilitate and encourage expanded options in their occupational expectations. It was hypothesized that such women would have occupational expectations that reflect a greater degree of gender integration or nontraditionality than women who do not participate in such activities. Other environmental or attribute variables such as parents' occupation, birth order, and constructs of self concept, were examined for intervening or modifying effects on the major premise.

A Bootstrap Method To Analyze An Intervention Model With Autoregressive Error Terms, Scott D. Mcknight

Dissertations

The analysis of a particular time-series intervention model involving lag one autoregressive (AR(1)) error terms is the focus of this dissertation. The method of ordinary least squares, and several two stage procedures that are commonly used to analyze this intervention model are examined. The two stage Cochrane-Orcutte, Durbin, and generalized least squares procedures each requires estimation of the AR(1) parameter in stage one before hypothesis testing about the intervention parameters can be performed in stage two. Using Monte Carlo experiments we show that the AR(1) estimates commonly used in these procedures are poor and consequently the stage two hypothesis tests …

The Theory And Applications Of Stratified Graphs, Reza Rashidi

Dissertations

Physical design is one of several stages in the design of a VLSI chip. In this stage, the specifications of an electrical circuit are converted into a geometrical model. Problems concerning the physical design stage can often be studied by means of graphs. The problems encountered here are routing problems and concern placement of vertices, which represent wires, into layers. All this gives rise to a class of graphs whose vertices are partitioned into classes. Such graphs are called stratified graphs. In this dissertation, we formally define stratified graphs, study their properties, and investigate various algorithmic problems related to these …

Effects Of Caffeine Consumption On Cardiovascular Indices, Attention, Task Performance, And Memory Retention In Children, Suzanne L. Keller

Dissertations

Caffeine is one of the most commonly used drugs in the western world today. Average intake of caffeine in the United States has been estimated at greater than 200 mg daily per person. Although plagued by inconsistencies, and methodological problems, research suggests that this level of caffeine ingestion may have significant effects on cardiovascular functioning, and behavioral processes such as attention, cognitive processing, memory, and task performance.

Although children consume significant quantities of caffeine, very little research has been done on the effects of caffeine in children. The limited findings suggest that caffeine consumption may affect the cognitive and behavioral …

Interim Outcomes And Change Processes: A Case Study Of School Restructuring, Meg V. Blinkiewicz

Dissertations

The purpose of this qualitative case study was two-fold: (1) to describe interim outcomes that occurred within a restructuring school district and the change processes related to each outcome; and (2) to confirm or expand what is known about educational restructuring. Individual interviews were conducted with fifty-five (55) persons including central office administrators, principals, teachers, support staff, parents, and School Board members. Approximately 120 hours were spent in the field observing meetings, classroom activities, and other events. Existing documentation (meeting minutes, policies, and procedures) also was reviewed.

This study produced detailed descriptions o f six categories of interim outcomes that …

Analytical And Simulation Models Of Weaving Area Operations Under Non-Freeway Conditions, Muhammad Shahid Iqbal

Dissertations

The Highway Capacity Manual covers adequately the operation of weaving areas on freeways. Weaving on non-freeway facilities, however, has not been addressed as yet. This research effort presents a state-of-the-art procedural analytical approach and simulation models for the analysis of the level of service and operation of non-freeway weaving areas. Weaving under non-freeway conditions is classified into two broad categories; basic weave and ramp weave. The analytical models for these two weaving categories are calibrated and validated based on data obtained from several sites selected in the states of New Jersey and New York. New level of service criteria are …

Local Thermal Stress Factor Of Pipe-Nozzle, David Chihwei Chen

Dissertations

A comprehensive study of local thermal stresses at the juncture of pipe-nozzle is presented in this thesis. The thermal loading is assumed to be a linear thermal gradient across the thickness of the pipe and nozzle. Currently, there exists neither experimental nor analytical data that is sufficient for pressure vessel designers to analyze the local thermal stresses at the juncture of pipe-nozzle. In order to provide a comprehensive database to calculate these thermal stresses, the finite element technique is used to provide a series of local thermal stress factor plots as a function of pipe-nozzle geometrical parameters.

For the local …

Local Stress Factors Of Pipe-Nozzle Under Internal Pressure, Jih-Lian Jack Ha

Dissertations

This thesis presents a comprehensive study of local stresses around a pipe-nozzle due to internal pressure. The finite element method (FEM) was employed to provide a numerical solution which will furnish a database for stress analysts to compute local stresses of pipe-nozzle due to internal pressure. The local pressure stresses for both the pipe and the nozzle around the pipe-nozzle juncture are first normalized into pressure stress factors which are then plotted as functions of geometrical parameters, beta, β, (nozzle mean radius / pipe mean radius) and gamma γ, (pipe mean radius / pipe thickness). These local pressure stresses at …

Behavior Of Concrete And Slender Reinforced Concrete Columns Under Cyclic Axial Compression With Bidirectional Eccentricities, Byong Youl Bahn

Dissertations

A rational analysis of reinforced concrete (R/C) structures requires satisfactory modeling of the behavior of concrete under general loading patterns. The behavioral characteristics of concrete dominantly depends upon its load history. For the study of concrete behavior, parametric study and experimental investigation into the behavior of concrete under load history of random cycles are performed. Through parametric study, the applicability of the previous concrete models is examined and a physically motivated modeling for the cyclic stress-strain relationships is proposed. The present modeling of concrete under general cyclic loading is initiated to provide substantial applicability, flexibility of mathematical expressions and furthermore …
