A case study of seven participants in the STAT Internship Program was chosen to investigate five research questions. The research questions explored five broad areas: (1) the technology applications interns used, (2) issues that arose from their use of technology, (3) intern attitudes towards technology, (4)...

This study examined the professional identity of master's level students enrolled in a CACREP accredited training program. Professional identity was assessed through two instruments: the Beliefs about Counseling Scale and the Professional Identity and Engagement Scale which was developed for this study. The constructs of professional identity represented in the scales included belief in the acquisition of licensure and credentialing, the distinctiveness of professional counseling among other mental health professionals, pride in the counseling profession,...

This study identified a significant relationship between Adult Attention Deficit Disorder (Adult ADD) characteristics and the Old Dominion University Freshman Survey Probation Score. The Probation Score is used to identify potential academically at risk freshmen students. Academically at risk is defined as those students with less than a 2.0 GPA. The research found that as the number and severity of Adult ADD characteristics increased, as measured utilizing the Brown Adult ADD Scales, the higher the...

This research examined two similar groups of first grade students and two different approaches to reading instruction within a whole language/literature based curriculum. The sample population for this research was drawn from four randomly assigned first grade classes attending an elementary school with urban characteristics. Teacher selection was based on results from the Theoretical Orientation to Reading Profile. Teachers in the experimental group implemented an approach that utilized a daily format for reading instruction developed...

This case study seeks to provide insight into the community perception of character education in a large urban area that does not currently implement an explicit program in moral values. The community is established through adolescents in middle school, parents of the adolescents, school counselors and community members. Informants are selected in an attempt to ensure a diverse cross section of the middle school communities. Perceptions of character education are established through the process of...

This study is a comparative analysis of the structure, organization and activities of the nine non-profit (501 (c)(3)) mediation centers for the resolution of dispute (CDRC) in Virginia. Data for the analysis was collected through on-site interviews, in-depth case studies, and discussions with the leadership of the centers. The CDRCs suffer from funding shortfalls which pressure them to shift their attention away from their mission. They are dependent upon the state's court contracts for mediation...

Scheduling is an essential factor influencing the efficiency of any production system. The effectiveness of the scheduling system depends upon the interaction of the human and machine. Thus, to effectively design the interface between the human and the machine, the human factors professional must understand scheduling behavior and the information requirements of the scheduling task. The present study modeled human scheduling behavior and determined the information requirements of the scheduling task. The study also compared...

This study investigated the effect of client gender on several aspects of clinical decision-making processes and clinical judgement when a client presented with a combination of depressive and alcohol-dependent symptoms. Forty-four male and 44 female clinicians, who came from various mental health disciplines (i.e., psychology, social work, counseling, nursing, and psychiatry), volunteered to participate as subjects. The subjects were assigned to hear one of four audiotapes (two male tapes and two female tapes) in which...

A coupled structural-electrical modal finite element formulation for composite panels with integrated piezoelectric sensors and actuators is presented for nonlinear panel flutter suppression under yawed supersonic flow. The first-order shear deformation theory for laminated composite plates, the von Karman nonlinear strain-displacement relations for large deflection response, the linear piezoelectricity constitutive relations, and the first-order piston theory of aerodynamics are employed. Nonlinear equations of motion are derived using the three-node triangular MIN3 plate element. Additional electrical...

Obesity is an increasingly common public health problem with approximately one-half of the American adult population overweight and one-quarter considered obese. This alarming trend has led researchers to determine potential causative factors of excess weight gain in humans. However, it is difficult to discern whether perturbations that result in obesity are the cause or simply the result of the obese state. Diet-induced obesity is one of the animal models that allow researchers to address temporal...

The estimation of the adequacy of theoretical calculations on the atomic structure requires availability of the precise experimental data on radiative properties of the atoms. Such data is also required in astronomy and some important areas of technology. The lack of precision of traditional spectroscopic studies of atom presents a fundamental obstacle for progress in these areas. For example, in atomic rubidium, the best precision of the traditional spectroscopic results is on the order of...

The two-dimensional time dependent Navier-Stokes equations are used to investigate supersonic flows undergoing finite rate chemical reaction and radiation interaction for a hydrogen-air system. The explicit multi-stage finite volume technique of Jameson is used to advance the governing equations in time until convergence is achieved. The chemistry source term in the species equation is treated implicitly to alleviate the stiffness associated with fast reactions. The multi-dimensional radiative transfer equations for a nongray model are provided...

Observations arising from a linear regression model, lead one to believe that a particular observation or a set of observations are aberrant from the rest of the data. These may arise in several ways: for example, from incorrect or faulty measurements or by gross errors in either response or explanatory variables. Sometimes the model may inadequately describe the systematic structure of the data, or the data may be better analyzed in another scale. When diagnostics...

This research was designed to develop a model of organizational commitment by establishing a causal network among three individual characteristics--tenure, work motivation, and job satisfaction--two organizational/structural variables--decentralization and formalization,--and two job facets--the job characteristic model and job stress--as determinants of commitment. The proposed model was tested on male and female samples represented by five occupational groups ranging from blue collar to professional workers. Successive iterations of a path analytic technique indicated that across the five...

The problem solved in this dissertation is that of finding the stresses in an isotropic, linear, thermoelastic solid when a uniform heat flow is disturbed by the presence of an insulated circular hole with a radial edge crack. By superimposing a Mellin transform solution of the equations of thermoelasticity on a Michell series solution the author reduces the problem to a pair of singular integral equations which are then solved numerically. The stress intensity factors...

In an effort to reduce communication latency in mesh-type architectures, these architectures have been augmented by various types of global and reconfigurable bus structures. The static bus structures provide excellent performance in many areas of computation especially structured numerical computations, but they lack the flexibility required of many large numerical and non-numerical applications. Reconfigurable bus systems have the dynamic adaptability to handle a much wider range of applications. While reconfigurable meshes can often yield constant...

The generation mechanism of short wind waves is generally thought to be a viscous instability at the air-sea interface. The short, regular waves arising from a sudden wind on a still water surface have a dispersion relation which is characteristic of gravity-capillary waves. The effects of variable surface tension, viscosity and shear flow parameters on the behavior of these waves were studied. A numerical hydrodynamic stability analysis of a coupled laminar shear flow was accomplished...

Radiative transitions of hydrogenlike atoms in external magnetic fields of strength applicable to magnetic white dwarfs, i.e. B < 103 megagauss, have been investigated for field-free principal quantum numbers n < 6. Finite proton mass corrections are included. Relativistic corrections are also investigated. Transition probabilities are determined using the length, velocity, and acceleration forms of the electric dipole operator. Discrepancies between previous calculations and magnetic white dwarf observations of low-lying boundbound transitions have been studied....

This is a study of best approximation with certain geometric constraints. Two major problem areas are considered: best Lp approximation to a function in Lp (0,1) by convex functions, (m, n)-convex functions, (m, n)-convex functions and (m, n)-convex splines, for 1 < p < ∞ , and best uniform approximation to a continuous function by convex functions, quasi-convex functions and piecewise monotone functions.

The problem addressed in this dissertation is the existence and estimation of the parameters of a truncated Cauchy distribution. It is known that when a number of distributions with infinite support are truncated to a finite interval that the maximum likelihood estimator of the scale parameter fails to exist with positive probability. In particular, necessary and sufficient conditions which give rise to instances of non-existence have been found for the exponential (Deemer and Votaw (1955)),...

Investigation of the various chemical forms of selenium and sulfur in sediments and pore waters can provide information about various oxidation/reduction processes. Five cores were obtained from the Great Marsh, from April 1985 to June 1986. Sampling times coincided with the seasonal redox cycle known to occur within the marsh system. Sediments were analyzed for various selenium and sulfur phases. Iron monosulfides and elemental sulfur both display large seasonal changes in concentration and distribution with...
