Correlational Study of the UNT Neuropsych-Screen, the MMPI and Time among Chronic Pain Patients

Description: Although many theorists have speculated that chronic pain may be linked to some sort of central neuropsychological integration deficit, a review of the current literature reveals no empirical support for this theory. This study attempts to assess the severity, if any, of neuropsychological deficits in chronic pain subjects by using a neuropsychological screen developed at the University of North Texas. Also, presented are studies of correlations between the UNT Neuropsych-screen and the MMPI. t… more

Self Cognitions of Depressed Adolescents: a Personal Construct Approach

Description: The primary purpose of the study was to quantify the characteristics of certain self cognitions that occur in depressed adolescents. A secondary purpose was to assess the change that occurs in these self cognitions during a depressive episode. The intervention, in the form of guided imagery about a previous drug-using episode, was used to induce a mood change. The REP, a Personal Construct Theory measure, and the Beck Depression Inventory were used in a repeated measures design.

Polynomial Isomorphisms of Cayley Objects Over a Finite Field

Description: In this dissertation the Bays-Lambossy theorem is generalized to GF(pn). The Bays-Lambossy theorem states that if two Cayley objects each based on GF(p) are isomorphic then they are isomorphic by a multiplier map. We use this characterization to show that under certain conditions two isomorphic Cayley objects over GF(pn) must be isomorphic by a function on GF(pn) of a particular type.

Estimating Nonpoint Source Pollution in North Texas Watersheds through Remote Sensing and Geographic Information Systems

Description: Monitoring nonpoint source pollution in a large area is often impractical. However, estimating nonpoint pollution through use of empirical models such as the Universal Soil Loss Equation (USLE) provides a basis for identifying problem areas, and setting management priorities. The purpose of this study was to determine the feasibility of using Landsat imagery and existing geographic data to estimate the effects of land use changes on water quality in four North Texas watersheds over a twelve yea… more

Response of Freshwater and Saltwater Toxicity Test Species to Calcium and Salinity Concentrations Encountered in Toxicity Tests

Description: The responses of freshwater (Daphnia magna. Pimephales promelas) and saltwater (Mysidopsis bahia. Cyprinodon variegatus) toxicity test species to elevated calcium concentrations and changing salinity conditions were investigated. The use of salinity as a criterion for selection between saltwater and freshwater test species was investigated by conducting both calcium and salinity toxicity tests. Salinity was determined to be an inappropriate criterion under conditions encountered in this study.
