A Comparison of Cognitive Moral Development of Accounting Students at a Catholic University with Secular University Accounting Students

A Comparison of Cognitive Moral Development of Accounting Students at a Catholic University with Secular University Accounting Students

Date: April 1998
Creator: Koeplin, John P. (John Peter)
Description: Previous research has shown that accountants may be inadequate moral reasoners. Concern over this trend caused the Treadway Commission (1987) and the Accounting Education Change Commission (1990) to call for greater integration of ethics into the student's training. Ponemon and Glazer (1990) found a difference in cognitive moral development (CMD) between accounting students at a public university and a private university with a liberal arts emphasis. This study expands Ponemon and Glazer's research by examining two liberal arts universities, one a private, secular institution and one a Catholic institution. The primary research question asks if Catholic university accounting students manifest greater CMD growth than secular university accounting students. Additionally, this study examines and compares the priority that accounting students from the different institutions place on ethical values versus economic values. It was expected that Catholic university accounting students would manifest both greater CMD growth and a greater concern for ethical values over economic values when compared with non-Catholic university accounting students. The study utilized a two-phase approach. In the first phase, an organizational study of two institutions was made to determine how each strives to integrate moral development into their accounting students' education. In the second phase, lower-division and senior ...

Analysis of the Trypanosoma brucei Genome and Identification and Characterization of a Gene Family Encoding Putative EF-Hand Calcium-Binding Proteins

Analysis of the Trypanosoma brucei Genome and Identification and Characterization of a Gene Family Encoding Putative EF-Hand Calcium-Binding Proteins

Date: May 1998
Creator: DeFord, James H. (James Henry), 1956-
Description: The flagellum of Trypanosoma brucei contains a family of antigenically related EF-hand calcium-binding proteins which are called the calflagins. Genomic Southern blots indicated that multiple copies of calflagin genes occur in T brucei. All of the copies were contained in a single 23 kb Xhol-Xhol fragment. Genomic fragments of 2.5 and 1.7 kb were cloned that encoded calflagin sequences. Two new members of the calflagin family were found from genomic clone sequences. The deduced amino acid sequences of the genomic clones showed the calflagin genes were arranged tandemly along the genomic fragments and were similar to previously described calflagins. The calflagin genes were related by two unrelated 3' flanking sequences. An open reading frame that was unrelated to any calflagin was found at the 5' end of the 2.5 kb genomic fragment. Each encoded protein (~24,000u) contained three EF-hand calcium-binding motifs and one degenerate EF-hand motif. In general, variability among the T. brucei calflagins is greater than related proteins in T. lewisii and T. cruzi. This variability results from amino acid substitutions at the amino and carboxy termini, and duplication of internal segments.

Analysis of Thermoplastic Polyimide + Polymer Liquid Crystal Blends

Analysis of Thermoplastic Polyimide + Polymer Liquid Crystal Blends

Date: May 1998
Creator: Gopalanarayanan, Bhaskar
Description: Thermoplastic polyimides (TPIs) exhibit high glass transition temperatures (Tgs), which make them useful in high performance applications. Amorphous and semicrystalline TPIs show sub-Tg relaxations, which can aid in improving strength characteristics through energy absorption. The a relaxation of both types of TPIs indicates a cooperative nature. The semicrystalline TPI shows thermo-irreversible cold crystallization phenomenon. The polymer liquid crystal (PLC) used in the blends is thermotropic and with longitudinal molecular structure. The small heat capacity change (ACP) associated with the glass transition indicates the PLC to be rigid rod in nature. The PLC shows a small endotherm associated with the melting. The addition of PLC to the semicrystalline TPI does not significantly affect the Tg or the melting point (Tm). The cold crystallization temperature (Tc) increases with the addition of the PLC, indicating channeling phenomenon. The addition of PLC also causes a negative deviation of the ACP, which is another evidence for channeling. The TPI, PLC and their blends show high thermal stability. The semicrystalline TPI absorbs moisture; this effect decreases with the addition of the PLC. The absorbed moisture does not show any effect on the degradation. The addition of PLC beyond 30 wt.% does not result in an improvement ...

Anyone Lived in a Pretty How Hell: the Rhetoric of Universality in Bessie Head

Anyone Lived in a Pretty How Hell: the Rhetoric of Universality in Bessie Head

Date: May 1998
Creator: Edwards, George, Jr.
Description: This dissertation approaches the work of South African/Botswanan novelist Bessie Head, especially the novel A Question of Power, as positioned within the critical framework of the postcolonial paradigm, the genius of which accommodates both African and African American literature without recourse to racial essentialism. A central problematic of postcolonial literary criticism is the ideological stance postcolonial authors adopt with respect to the ideology of the metropolis, whether on the one hand the stances they adopt are collusive, or on the other oppositional. A key contested concept is that of universality, which has been widely regarded as a witting or unwitting tool of the metropolis, having the effect of denigrating the colonial subject. It is my thesis that Bessie Head, neither entirely collusive nor oppositional, advocates an Africanist universality that paradoxically eliminates the bias implicit in metropolitan universality.

A Behavioral Model for Detection of Acute Stress in Bivalves

A Behavioral Model for Detection of Acute Stress in Bivalves

Date: May 1998
Creator: Allen, H. Joel
Description: A behavioral model for acute responses in bivalves, was developed using time series analysis for use in a real-time biomonitoring unit. Stressed bivalves closed their shell and waited for the stressful conditions to pass. Baseline data showed that group behavior of fifteen bivalves was periodic, however, individuals behaved independently. Group behavior did not change over a period of 20 minutes more than 30 percent, however, following toxic exposures the group behavior changed by more than 30 percent within 20 minutes. Behavior was mathematically modeled using autoregression to compare current and past behavior. A logical alarm applied to the behavior model determined when organisms were stressed. The ability to disseminate data collected in real time via the Internet was demonstrated.

Biochemical Identification of Molecular Components Required for Cyanide Assimilation in Pseudomonas fluorescens NCIMB 11764

Biochemical Identification of Molecular Components Required for Cyanide Assimilation in Pseudomonas fluorescens NCIMB 11764

Date: May 1998
Creator: Chen, Jui-Lin
Description: Utilization of cyanide as a nutritional nitrogen source in P. fluorescens NCIMB 11764 was shown to involve a novel metabolic mechanism involving nonenzymatic neutralization outside of cells prior to further enzymatic oxidation within. Several cyanide degrading enzymes were produced by NCIMB 11764 in response to growth or exposure to cyanide, but only one of these cyanide, oxygenase (CNO), was shown to be physiologically required for assimilation of cyanide as a growth substrate.

Characterization of Aspartate Transcarbamoylase and Dihydroorotase in Moraxella Catarrhalis

Characterization of Aspartate Transcarbamoylase and Dihydroorotase in Moraxella Catarrhalis

Date: May 1998
Creator: Fowler, Michael A. (Michael Allen), 1961-
Description: Bacterial aspartate transcarbamoylases (ATCase's) are divided into three classes that correspond to taxonomic relationships within the bacteria. The opportunistic pathogen Moraxeila catarrhalis has undergone several reclassifications based on traditional microbiological criteria. The previously uncharacterized ATCase from M. catarrhalis was purified to homogeneity and its chemical properties characterized. The ATCase from M. catarrhalis is a class C ATCase with an apparent molecular mass of 480-520 kDa. The M. catarrhalis ATCase is a dodecomer composed of six 35 kDa polypeptides and six 45 kDa polypeptides. The enzyme has an unusually high pH optimum of greater than pH 10. The enzyme exhibited hyperbolic kinetic with a Km for aspartate of 2 mM. A single, separate 78 kDa dihydroorotase from M. catarrhalis was identified and it was not associated with ATCase. These data support the reclassification of M. catarrhalis out of the Neisseriaceae family.

Classification of Denial in Sex Offenders; an Investigation of Response Styles

Classification of Denial in Sex Offenders; an Investigation of Response Styles

Date: May 1998
Creator: Cruise, Keith R.
Description: Standard psychological assessment instruments have not produced consistent results by which decisions can be made regarding the appropriate placement and legal disposition of an individual who has committed a sexual offense. The purpose of the present study was to systematically investigate deception and dissimulation as measured by three assessment instruments commonly utilized with sex offenders. A denial classification system was utilized in order to classify offenders into categories based on their level of admission to the legal system. The four group classification system did not produce significant differences on all measures of deception and dissimulation. Contrary to previous research, admitters were found to respond more defensively than deniers on one of the assessment instruments. In addition, partial deniers were identified as responding significantly differently from both admitters and deniers on a separate instrument. The differences found suggest that sex offenders' level of deception is multifaceted. Difficulties in identifying classificatory strategies and implications for theoretical conceptions of denial within this population are discussed.

Conception and Design of Constructed Wetland Systems to Treat Wastewater at the Biosphere 2 Center with Use of Reaction Rate Models and the Habitat Evaluation Procedure to Determine the Effects of Designing for Wildlife Habitat on Treatment Efficiency

Conception and Design of Constructed Wetland Systems to Treat Wastewater at the Biosphere 2 Center with Use of Reaction Rate Models and the Habitat Evaluation Procedure to Determine the Effects of Designing for Wildlife Habitat on Treatment Efficiency

Date: May 1998
Creator: Clingenpeel, Glenn C. (Glenn Christopher)
Description: A study was undertaken to explore relationships between wetland characteristics which make them efficient water purifiers versus their ability to serve as wildlife habitat. The effects of designing constructed wetlands for improved habitat on water treatment efficiencies were quantified. Results indicate that some sacrifice in treatment efficiency is required and that the degree of efficiency reduction is dependant upon pollutant loading rates. However, sacrifice in efficiency is much smaller than increase in habitat quality, and can be offset by increasing wetland area. A practical, theoretical application was then attempted.

Convergence of Self and Other Ratings of Personality: a Structural Equation Analysis

Convergence of Self and Other Ratings of Personality: a Structural Equation Analysis

Date: May 1998
Creator: McElhenie, Michael K. (Michael Keith)
Description: Recently, multi-source feedback has been a popular way of providing performance-related feedback to individuals in many organizations. Many who use multi-source feedback consider Rating Convergence, others seeing target individuals as they see themselves, to be a positive outcome of this process. However, the variables that account for Rating Convergence are not known. This study investigated whether the personality factor Extroversion and Behavioral Consistency, acting as a moderator variable, could account for Self-other Rating Convergence, particularly the Convergence between self and peer Ratings. The sample consisted of 235 mid-level managers from a variety of industries who were participants in individual career development workshops. Using structural equation modeling, the results indicated that a model consisting of a single Extroversion factor could account for the convergence of self-peer ratings. This finding calls into question the significance of Rating Convergence when using multi-source rating instruments that provide feedback on trait characteristics since it may be heavily influenced by a single personality factor rather than observers' comprehensive understanding of the ratee's performance.

The Destruction of the Imagery of Saint Thomas Becket

The Destruction of the Imagery of Saint Thomas Becket

Date: May 1998
Creator: Cucuzzella, Jean Moore
Description: This thesis analyzes the destruction of imagery dedicated to Saint Thomas Becket in order to investigate the nature of sixteenth-century iconoclasm in Reformation England. In doing so, it also considers the veneration of images during the late Middle Ages and the Renaissance. Research involved examining medieval and sixteenth-century historical studies concerning Becket's life and cult, anti-Becket sentiment prior to the sixteenth century, and the political circumstances in England that led to the destruction of shrines and imagery. This study provides insight into the ways in which religious images could carry multifaceted, ideological significance that represented diversified ideas for varying social strata--royal, ecclesiastical and lay.

Development and Application of an Assessment Protocol for Watershed Based Biomonitoring

Development and Application of an Assessment Protocol for Watershed Based Biomonitoring

Date: May 1998
Creator: Schwartz, Joseph Howard
Description: With numerous bioassessment methodologies available, a regional protocol needs to be developed to ensure that results are comparable. A regional assessment protocol was developed that includes collecting five benthic macroinvertebrate samples, identifying organisms to genus, and calculating the following metrics: Number of Taxa, Total Number of Individuals, Simpson's Diversity Index, Shannon's Diversity Index, Percent Contribution of Dominant Taxa, Hilsenhoffs Biotic Index, and Percent Contribution of Dipterans. Once the protocol was developed, it was used to assess the Bayou Chico tributaries and watershed. All three tributaries had been significantly impacted by human activity as had the watershed as a whole. This study indicates that a regional protocol could be developed and is appropriate for biomonitoring at the watershed scale.

The Differences in the Media Constructions of the Narratives of Male and Female Political Candidates

Date: May 1998
Creator: Paschal, Lori L. (Lori Lynne)
Description: This study views the media as a powerful agent which constructs the narratives of political candidates. In order to determine whether the media constructs the narratives of male and female political candidates differently, newspaper articles were analyzed for two 1994 Congressional races, each involving a male and a female candidate (Thurman versus Garlits and Byrne versus Davis). The first research question posed the following question: Does the media devote more coverage to male or female candidates? The next question concerned media endorsements of the candidates. Third, the settings in which the media portrayed the male and female candidates were compared. Finally, differences in the media's attitude toward male and female candidates were analyzed.

The Effect of Decreasing Defect Probabilities on Quality Control Inspection

The Effect of Decreasing Defect Probabilities on Quality Control Inspection

Date: May 1998
Creator: Segal, Jo Ann
Description: This study was a follow up to P. C. Dams' (1996) unpublished University of North Texas masters thesis, The effect of defect probability during training on inspection accuracy in a quality control simulation. Graphics of computer circuit boards were presented in dyads with an error free sample on the left and a comparison on the right. Comparisons had either a rotation or transposition defect, or were error free. Subjects had 10-s to accept or reject the comparison as identical to the sample. They were trained using two different stimulus fading procedures (using descending defect probabilities) and immediate feedback. Defect probabilities for the Tens were 0.60, 0.50, 0.40, and 0.30 and for the Twenties were 1.00, 0.80, 0.60, and 0.40. The last 4 pretraining and posttraining sessions were compared and the posttraining performance of the Twenties, as compared to the Tens, demonstrated greater improvement over pretraining performance. No firm conclusions could be drawn as to the effectiveness of either training procedure. The significance of the current investigation and suggestions for future research are discussed.
